The airport handled an actual passenger traffic of 30.48 million passengers per annum (MPPA) during FY 2025-26 and has continued to witness steady growth in air traffic, reaffirming its strategic significance within India’s civil aviation network.

The genesis of RGIA dates back to November 2000, when the Government of Andhra Pradesh and the Airports Authority of India (AAI) executed a Memorandum of Understanding (MoU) for the development of a greenfield airport at Hyderabad under the Public-Private Partnership (PPP) model. Pursuant to this MoU, GMR Hyderabad International Airport Limited, hereinafter referred to as “GHIAL” or “the Airport Operator”, was incorporated on 17th December, 2002 to design, finance, construct, develop, operate and maintain a modern, efficient and world- class greenfield airport at Shamshabad, Hyderabad. The development of RGIA under the PPP framework represents a significant milestone in airport infrastructure development in India and reflects the policy objective of leveraging private sector participation for creation of aviation infrastructure.

The Concession Agreement for the development, construction, operation and maintenance of the Airport was executed on 20 December 2004 between the Government of India and GHIAL. Subsequently, the Airport commenced commercial operations on 23 March 2008 and has since evolved into one of the country’s key aviation gateways.

In accordance with the provisions of the AERA Act, 2008 and the applicable Concession Agreement, GHIAL has submitted its Multi-Year Tariff Proposal (MYTP) for the 4th Control Period (2026-2031) for consideration by the Authority. The MYTP comprises of:

(i) Revised True-up submissions pertaining to the Pre-Control Period Entitlement (PCPE), 1st Control Period, 2nd Control Period

(ii) True-up of the Third Control Period based on the audited financial statements for FY 2022–FY 2025 and the unaudited actuals for FY 2026;

(iii) Projections for the Fourth Control Period commencing from 1 April 2026 and ending on 31 March

2031.

The submissions include detailed information relating to traffic projections, Capital Expenditure (Capex), Operating Expenditure (Opex), Non-Aeronautical Revenue (NAR), and other relevant parameters forming the basis for determination of aeronautical tariff for the Fourth Control Period.

During the preparation of this Consultation Paper, the Authority undertook a comprehensive examination of the MYTP submissions and the supporting documents furnished by GHIAL. The assessment included scrutiny of the audited financial statements pertaining to the Third Control Period. For FY 2025-26, unaudited actual financials furnished by GHIAL were also relied upon for the purpose of preparation of this Consultation Paper.

Accordingly, the Authority has issued this Consultation Paper setting out its proposals as part of the tariff determination exercise for the Fourth Control Period in respect of Rajiv Gandhi International Airport, Hyderabad.

The Authority shall duly consider written, evidence-based comments, suggestions and feedback received from stakeholders on the proposals contained herein and shall issue the Final Tariff Order for aeronautical services after taking into account stakeholder submissions on merits.

Consultation Paper No: 02/2026-27 Page 2 of 308The Authority would further like to emphasise that the timelines prescribed for the consultation process cannot be altered and needs to be strictly adhered to. Stakeholders are, therefore, requested to submit their comments and inputs strictly within the timelines specified in this Consultation Paper.

1. BACKGROUND

1.1. Introduction

1.1.1. Rajiv Gandhi International Airport (hereinafter referred to as “RGI Airport”, “RGIA” or “the Airport”), Hyderabad, is a Major Airport as per the provisions of the Airports Economic Regulatory Authority of India Act, 2008, based on the annual passenger throughput criteria prescribed thereunder. GMR Hyderabad International Airport Limited (GHIAL) (hereinafter referred to as “GHIAL”, “HIAL”, or “the Company”) was incorporated on 17 December 2002 as a Special Purpose Vehicle (SPV) for the design, financing, construction, operation, and maintenance of a world-class greenfield international airport at Shamshabad, Hyderabad.

1.1.2. The development of RGIA traces its origin to the Memorandum of Understanding executed in November 2000 between the Government of Andhra Pradesh and the Airports Authority of India (AAI) for the establishment of a greenfield airport project under the PPP framework. Under the proposed structure, the Government and AAI together were envisaged to hold a 26% equity stake, while the remaining 74% was to be held by a private sector partner. Following a competitive international bidding process, the project was awarded to a consortium comprising GMR Group and Malaysia Airports Holdings Berhad (MAHB).

1.1.3. In September 2003, the project stakeholders executed the Shareholders’ Agreement and entered into arrangements relating to State support and subsidy of over Rs. 4 billion for project implementation.

Subsequently, a Concession Agreement was signed between Ministry of Civil Aviation (MoCA) and GHIAL on 20th December 2004 that authorized GHIAL for the Development, Construction, Operation and Maintenance of the Hyderabad International Airport.

1.1.4. In addition to financial support, the State Government facilitated land availability for the Airport project. A Land Lease Agreement (LLA) was executed in this regard between the State Government (Lessor) and GHIAL (Lessee) on 30th September 2003.

1.3. Tariff Setting Principles for GHIAL

1.3.1. Airports Economic Regulatory Authority of India (AERA) was established by the Government of India vide notification No. GSR 317(E) dated 12.05.2009. The function of AERA, in respect of Major Airports, are specified in section 13(1) of The Airports Economic Regulatory Authority of India Act, 2008 (‘AERA Act’ or ‘the Act’) read with AERA (Amendment) Act 2019 and 2021, which are as below:

a) To determine the tariff for aeronautical services taking into consideration i. Capital expenditure incurred and timely investment in improvement of airport facilities; ii. Quality of services provided and other relevant service-related considerations;

iii. Costs associated with improvement in efficiency; iv. Economic and viable operation of major airports; v. Revenue received from services other than aeronautical services; vi. Concessions offered by the Central Government under agreements, memoranda of understanding, or other arrangements; and vii. Any other factor considered relevant for the purposes of the Act.

Provided that different tariff structures may be determined for different airports having regard to all or any of the above considerations specified at sub-clauses (i) to (vii); b) to determine the amount of development fees in respect of major airports;

c) to determine the amount of passenger service fee levied under rule 88 of the Aircraft Rules,1937 made under Aircraft Act, 1934 (22 of 1934); d) to monitor the set performance standards relating to quality, continuity and reliability of service as may be specified by the Central Government or any authority authorized by it in this behalf;

e) to call for such information as may be necessary to determine the tariff under clause 13(1)(a). f) to perform such other functions relating to tariff, as may be entrusted to it by the Central Government or as may be necessary to carry out the provisions of this Act.”

1.3.2. The terms “aeronautical services” and “Major Airports” are defined in Sections 2(a) and 2(i) of the Act, respectively

Consultation Paper No: 02/2026-27 Page 24 of 308BACKGROUND

1.3.3. As per the AERA Act, 2008, the aeronautical service means any services provided: “

(a) for navigation, surveillance and supportive communication thereto for air traffic management;

(b) for the landing, housing or parking of an aircraft or any other ground facility offered in connection with aircraft operations at any Airport;

(c) for ground safety services at an Airport;

(d) for ground handling services relating to aircraft, passengers and cargo at an Airport;

(e) for the cargo facility at an Airport;

(f) for supplying fuel to the aircraft at an Airport; and

(g) for a stakeholder at an Airport, for which the charges, in the opinion of the Central Government for the reasons to be recorded in writing, may be determined by the Authority”

1.3.4. AAI (Airports Authority of India) under Ministry of Civil Aviation, Government of India, being the sole service provider, handles Air Navigation Services (ANS) across the country including the Hyderabad Airport. Thus, the tariff for ANS is presently determined and regulated by the Ministry of Civil Aviation

(MoCA) at national level to ensure uniformity across airports. All assets, expenses and revenues pertaining to ANS are accordingly considered separately by the MoCA while determining the tariff for ANS.

1.6. Matters before the Hon’ble Supreme Court

1.6.1. Authority vide its Order No. 12/2021-22 dated 31st August 2021, determined the Aeronautical tariff for the Third Control Period. GHIAL by filing an AERA Appeal No. 04/2021, before the Hon’ble Telecom Disputes Settlement and Appellate Tribunal (“TDSAT”) challenged certain decisions of the Authority contained therein. The Hon’ble TDSAT pronounced its judgment on February 14, 2024.

1.6.2. In its judgment dated 14th February 2024, Hon’ble TDSAT has decided certain issues by relying upon its earlier judgments dated 21.07.2023 and 06.10.2023, passed in DIAL 2nd & 3rd Control Period Appeals and MIAL 2nd & 3rd Control Period Appeals, respectively. In all these judgements including the judgment dated 14.02.2024, in respect of GHIAL 3rd Control Period appeal certain issues have been decided in favor of the Airport Operators and on certain issues the decisions of the Authority have been upheld. All these judgments of Hon’ble TDSAT have been challenged in the Hon’ble Supreme Court by AERA by filing Civil Appeals there and these Civil Appeals are presently sub-judice. Therefore, the issues raised in the Civil Appeals filed by AERA against Hon’ble TDSAT judgments dated 21.07.2023, 06.10.2023,

14.02.2024, are not yet finally adjudicated and hence yet to attain finality.

1.6.3. GHIAL, in its Multi-Year Tariff Proposal (MYTP) for the Fourth Control Period, has stated that the findings and directions of the Hon’ble TDSAT decided in favour of the Airport Operator have been factored into its tariff proposal and corresponding financial submissions.

Consultation Paper No: 02/2026-27 Page 28 of 308BACKGROUND

1.7. MYTP of GHIAL for the Fourth Control Period

1.7.1. GHIAL submitted the Multi-Year Tariff Proposal (MYTP) for the Fourth Control Period on 26th June 2025, for aeronautical services at Rajiv Gandhi International Airport, Hyderabad, for the Authority’s consideration seeking revision of tariffs for earlier Control Periods and approval of tariff for the ensuing Fourth Control Period, i.e., from 1st April 2026 to 31st March 2031. In its proposal GHIAL has factored the decisions of Hon’ble TDSAT as passed vide its judgment dated 14.02.2024, wherein, the Hon’ble TDSAT has decided certain issues by relying upon its earlier judgments dated 21.07.2023 and 06.10.2023, passed in DIAL 2nd & 3rd Control Period Appeals and MIAL 2nd & 3rd Control Period Appeals, respectively. As per GHIAL, these decisions/orders, have implications for True up of earlier Control Periods, including the Pre-Control Period Entitlement, First Control Period, Second Control Period and Third Control Period, as well as for the treatment of various Regulatory Building Blocks for the Fourth Control Period.

1.7.2. However, the Authority has challenged the decisions of the Hon’ble TDSAT by filing Civil Appeals in the Hon’ble Supreme Court under Section 31 of AERA Act, 2008. These Civil Appeals filed by AERA were opposed by the Airport Operators on the ground that AERA, being a Tariff determining Authority, is a quasi-judicial body and therefore, it cannot file Appeal against the judgement of Hon’ble TDSAT which is an appellate Authority.

1.7.3. The Hon’ble Supreme Court vide its judgement dated 18th October 2024, rejected the contentions of Airport Operators and has held that the appeals filed by the Authority under Section 31 of the AERA Act, 2008, against the Hon’ble TDSAT orders are maintainable on the ground that AERA is a necessary party in the Appeals filed before the Hon’ble TDSAT and the Authority is the custodian of public interest and for protecting public interest it can file Civil Appeal under Section 31 of the AERA Act, 2008. The Hon’ble Supreme Court has now listed these Civil Appeals filed by the Authority for hearing on merit and are pending before Hon’ble Supreme Court for final settlement and thus are sub-judice.

1.7.4. The Authority has carefully examined the issue of factoring the above-mentioned orders of the Hon’ble TDSAT in the Fourth Control Period Tariff Order. The Authority has utmost regards for the directions of the Appellate Authority. However, the Authority has challenged these orders in Hon’ble Supreme Court under section 31 of AERA Act, 2008, and Hon’ble Supreme Court is presently hearing these matters. Thus, the issues raised in these Civil Appeals filed by the Authority are not finally settled and the Hon’ble Supreme Court is seized of the matters. Therefore, the Authority notes that under such circumstances if it decides to implement the Hon’ble TDSAT order without finally settling the issues before the Hon’ble Supreme Court and revision in tariff is effected considering GHIAL’s submissions on the basis of Hon’ble TDSAT judgments, for the Fourth Control Period, then it shall lead to a significant increase in Aeronautical tariff which will have to be borne by the Airport users as GHIAL will start recovery of increased tariff from the Airport users. However, if at a later stage, the Civil Appeals filed by the Authority are upheld or decided in AERA’s favour, then it will not be possible to refund excess charges collected from the Airport users during this period on account of increase in tariff. Thus, there will be substantial over recovery by the Airport Operator at the cost of Airport Users. Due to all these factors, GHIAL would have unjust enrichment at the cost of Airport users. All these factors clearly establish that considering GHIAL submissions of giving effects to the Hon’ble TDSAT judgement without finally settling the issues before Hon’ble Supreme Court, is not in public interest, more so when the Hon’ble Supreme Court is seized up of all these issues and is hearing these Civil Appeals. On the contrary, Authority is of view that public interest

Consultation Paper No: 02/2026-27 Page 29 of 308BACKGROUND would be better served if Authority takes decisions on the basis of final decision of Hon’ble Supreme Court of India on these issues.

1.7.5. Considering the above and in public interest, the Authority proposes to continue the tariff determination exercise consistent with the decisions taken in the Tariff Order for the Third Control Period. The final decision with regard to the issues raised by the Authority in the Civil Appeals will be taken once the matters attain finality in the proceedings before the Hon’ble Supreme Court.

1.7.6. Further, GHIAL, vide email dated 02.05.2026, furnished actual operational and financial data for FY 2025- 26, including information relating to passenger and aircraft traffic, operating expenditure, non-aeronautical revenues, and Regulatory Asset Base (RAB). The aforesaid information was submitted to facilitate the Authority’s examination of the true-up exercise and the regulatory assumptions forming part of the MYTP for the Fourth Control Period.

1.7.7. As part of the tariff determination process for the Fourth Control Period, the Authority engaged M/s PricewaterhouseCoopers (PwC) as an independent Tariff Consultant to carry out a detailed review of the Multi-Year Tariff Proposal (MYTP) submitted by GHIAL. PwC assisted the Authority in verifying and validating the data and supporting documents submitted by GHIAL, including audited financial statements, Fixed Asset Register (FAR), construction and contract records, expenditure details, traffic and financial information. PwC also supported the Authority in examining whether the treatment of various regulatory building blocks is consistent with the Authority’s regulatory principles and tariff determination framework.

Also, the Authority engaged M/s RITES Limited as an independent Capital Expenditure (Capex) Consultant to evaluate the capital expenditure proposals submitted by GHIAL for the Fourth Control Period.

The review covered the need, scope, size, cost and capitalization schedule of the proposed projects, as well as their alignment with traffic growth and operational requirements. The assessment and recommendations of the independent Capex Consultant form an integral part of this Consultation Paper.

1.7.8. The independent consultant further assisted the Authority in assessing whether the proposed treatment of various regulatory building blocks is consistent with the Authority’s established regulatory principles, methodologies, and tariff determination framework.

1.7.9. The Authority, through the independent consultant, has sought from GHIAL additional information, supporting documents, and clarifications relating to the true-up exercise for previous control periods as well as the assumptions underpinning projections for the Fourth Control Period. Such information has been sought to facilitate a comprehensive examination of the MYTP and to ensure that the regulatory treatment accorded to various building blocks is supported by adequate justification, documentary evidence, and prudent forecasting assumptions. The timelines of various submissions made by GHIAL with regards to

the MYTP for the Fourth Control Period is as below:

Consultation Paper No: 02/2026-27 Page 45 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Authority’s examination regarding True Up of Traffic for the Third Control Period

5.3.5. The Authority has examined passenger traffic submissions made by GHIAL as part of its MYTP for the true-up of the Third Control Period. A comparison between passenger traffic projected by the Authority in the Tariff Order for the Third Control Period and actual passenger traffic reported by GHIAL is presented

in the table below:

Table 13: PAX Traffic Variation between the Authority’s projections and actuals for the Third Control Period FY ending March (in Mn) FY22 FY23 FY24 FY25 FY26 Total Total PAX Traffic decided by the

12.95 21.51 23.36 25.44 29.29 112.55 Authority in the TCP order (A) Total PAX Traffic as per actuals

5.3.6. The Authority, vide its Tariff Order for the Third Control Period (FY22 – FY26), had projected the total passenger traffic at Rajiv Gandhi International Airport, Hyderabad ("RGIA") at 112.55 million passengers cumulatively over the five-year control period. As against the said projection, the actual passenger throughput stood at 118.12 million passengers, reflecting an aggregate positive variation of approximately 5% over the control period.

5.3.7. Actual passenger traffic in FY22 stood at 12.43 million as against the projected 12.95 million, reflecting a shortfall of approximately 4%. The said shortfall is directly attributable to the second wave of the COVID- 19 pandemic.

5.3.8. Actual passenger traffic in FY23 was 21.00 million as against the projected 21.51 million, reflecting a marginal shortfall of approximately 2%. The variation is attributable to slower-than-anticipated recovery of international passenger traffic, particularly on long-haul routes.

5.3.9. Actual passenger traffic in FY24 stood at 25.04 million as against the projected 23.36 million, reflecting a positive variation of approximately 7%. The higher-than-projected throughput is attributable to pent-up travel demand following the easing of all pandemic-related restrictions.

5.3.10. Actual passenger traffic in FY25 stood at 29.17 million as against the projected 25.44 million, reflecting a significant positive variation of approximately 15%. The said variation is attributable to a confluence of factors, augmented terminal capacity enabling handling of higher passenger volume and launch of new domestic and international routes.

5.3.11. Actual passenger traffic in FY26 stood at 30.48 million as against the projected 29.29 million, reflecting a positive variation of approximately 4%. The said variation is attributable to sustained growth in air travel demand and continued expansion of domestic and international route networks.

5.3.12. The Authority further notes that actual passenger traffic for the Third Control Period exceeded the estimates considered by the Authority in the Tariff Order for the Third Control Period. The key factors contributing

to this growth include the following: • Improved connectivity to domestic and international destinations. • Increase in regional economic activity • Recovery and growth in travel demand after the COVID-19 pandemic

Consultation Paper No: 02/2026-27 Page 46 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.3.13. The Authority independently has also verified the passenger traffic data with the traffic data available on the Airports Authority of India website. The revised passenger traffic submitted by GHIAL for the Third Control Period is consistent with the data available from AAI.

5.3.14. The Authority has also examined the variation between Air Traffic Movements projected by the Authority at the time of tariff determination for the Third Control Period and the actual ATMs submitted by GHIAL.

The comparison is shown in table below:

Table 14: ATM Variation between the Authority’s Projections and Actuals for the Third Control Period FY ending March FY22 FY23 FY24 FY25 FY26 Total Total ATM Projected by the 113,485 185,235 199,483 217,341 251,032 966,576 Authority in the TCP order (A) Total ATM as per actuals (B) 113,926 158,747 176,286 202,395 207,900 859,194 Variation (B-A) 441 (26,488) (23,197) (14,946) (43,132) (107,382) Variation (%) – Increase/(Decrease) 0% (14%) (12%) (7%) (17%) (11%)

5.3.15. As can be seen in the table above, the actual ATMs during the Third Control Period were lower than the ATMs projected by the Authority at the time of tariff determination for the Third Control Period. The highest variation was observed in FY 2025-26, where actual ATMs were lower by approximately 17% compared to the projected ATMs.

5.3.16. The Authority notes that the lower-than-projected ATMs were primarily due to improvement in passenger load factors and changes in fleet deployment. The passenger load factors increased from around 68% in FY 2021-22 to around 84% in FY 2024-25, thereby enabling airlines to carry higher passenger volumes without a proportionate increase in aircraft movements. Further, the declining share of ATR aircraft from 26% to 22% in FY 2024-25 also contributed to more efficient capacity deployment and lower ATMs compared to projections.

5.3.17. The Authority independently has also verified the ATM data with the data available on the Airports Authority of India website. Revised ATM data submitted by GHIAL for the Third Control Period is consistent with the data available from AAI.

Cargo Traffic

5.3.18. The Authority has also examined the variation between cargo traffic projected by the Authority at the time of tariff determination for the Third Control Period and the actual cargo traffic submitted by GHIAL. The

comparison is shown in table below:

Table 15: Cargo Traffic Variation between the Authority’s Projections and Actuals for the Third Control Period FY ending March (MT) FY22 FY23 FY24 FY25 FY26 Total Cargo Traffic Projected by the Authority in 136,372 144,554 161,501 177,219 189,821 809,467 the TCP Order (A) Cargo Traffic as per actuals (B) 140,075 142,434 149,812 167,665 192,458 792,444 Variation (B-A) 3,703 (2,120) (11,689) (9,554) 2,637 (17,023) Variation (%) – Increase/(Decrease) 3% (1%) (7%) (5%) 1% (2%)

5.3.19. As seen from table above, the overall cargo traffic for the Third Control Period was lower than the projections considered by the Authority by around 2%. The variation was relatively higher in FY 2023-24 and FY 2024-25, while the variation in other years was comparatively limited.

Consultation Paper No: 02/2026-27 Page 47 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.3.20. The variation between projected and actual cargo traffic during the Third Control Period is primarily due to the impact of the COVID-19 pandemic and the uneven recovery that followed. As shown in the table above, disruptions led to slower and more volatile recovery in the initial years, with deviations narrowing as conditions stabilized in later years.

5.3.21. The Authority has also independently verified the cargo traffic data with the data available on the Airports Authority of India website. The revised cargo traffic submitted by GHIAL for the Third Control Period is consistent with the data available from AAI.

5.3.22. In view of the above facts and figures, the Authority proposes to consider Traffic for true-up of the Third Control Period as presented in Table 11.

5.4. True up of Capital Expenditure (Capex), Depreciation and Regulatory Asset Base (RAB) for the Third Control Period Capital Expenditure submitted by GHIAL for True up of the Third Control Period Expansion project for 34 MPPA

5.4.1. GHIAL has submitted that RGIA witnessed significant traffic growth during FY2017 to FY2019, which required GHIAL to revisit the earlier expansion plan approved by the Authority in Order No. 34/2019-20 for the determination of Second Control Period, for expansion to 20 MPPA. Accordingly, GHIAL revised the capacity expansion plan and initiated expansion of RGIA to 34 MPPA to cater to traffic growth expected during determination of the Third Control Period.

5.4.2. GHIAL has submitted a total capital expenditure of Rs. 7,177.51 Crores for true up of the Third Control Period as against the approved capital expenditure of 6,090.78 Crores in the Third Control Period tariff

order. The Asset category wise (head wise) details of CAPEX submitted by GHIAL for the Third Control

Period are presented below:

5.4.3. GHIAL has submitted that the expansion contract management was planned through a mix of independent packages and EPC contracts. In respect of EPC contracts, GHIAL invited tenders through International Competitive Bidding. Post negotiation of financial bids, the contracts were broken into two packages in

Consultation Paper No: 02/2026-27 Page 48 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

order to optimise project cost and avail input tax credit on supplies under Goods and Services Tax (“GST”).

The two packages comprised: i. All works other than Airport Systems, awarded to M/s Larsen & Toubro Limited (“L&T”). ii. Airport Systems, awarded to M/s Megawide Construction Corporation (“MCSP”) and M/s Beumer Group.

In addition, independent packages were awarded through competitive bidding to M/s MVR and M/s VNC for specific airside and road infrastructure works respectively.

5.4.4. GHIAL has submitted the actual cost incurred towards the 34 MPPA expansion project. As per GHIAL’s submission, the total expansion capex incurred amounts to Rs. 5,671.34 Crores before IDC, which is higher than the cost of Rs. 5,596.23 Crores submitted by GHIAL during the Third Control Period tariff determination and higher than the cost of Rs. 4,820.05 Crores before IDC approved by the Authority in

Order No. 12/2021-22.

5.4.5. The key reasons for increase in project cost over the amount approved by the Authority, as submitted by GHIAL, are as follows: a) L&T Contract – All works other than Airport Systems

5.4.6. GHIAL has submitted that the original L&T contract value, including changes submitted to the Authority during the Third Control Period tariff determination, was Rs. 3,063.98 Crores. The final cost of the L&T contract as submitted by GHIAL is Rs. 3,500.70 Crores, representing an increase of Rs. 436.72 Crores.

GHIAL has attributed the increase to the following: i. Changes in scope of works and utilisation of contingency budget – Rs. 228.11 Crores:

During execution of the expansion works, GHIAL undertook additional works from the contingency budget, including revised layout of south east remote apron along with taxilane works, four Rapid Exit Taxiways in compliance with CAT-II requirements, aviation fuel hydrant system works at west pier, additional filling at north west apron, electrical load enhancements from 14.8 MW to 37.6 MW, grid changes in the terminal building from 9m x 9m to 18m x 18m and 18m x 36m, façade modifications, enhancements in toilet specifications, increase in warehouse and office areas and other design enhancements.

Consultation Paper No: 02/2026-27 Page 49 of 308TRUE UP FOR THE THIRD CONTROL PERIOD ii. Extended stay cost – Rs. 112.10 Crores:

GHIAL has submitted that the project duration was extended for the terminal building from the original planned completion to FY2024 on account of multiple unforeseen lockdowns and restrictions due to COVID-19, logistics disruptions and manpower exodus, resulting in extended stay cost implications.

iii. Price escalation for L&T contract – Rs. 76.70 Crores:

GHIAL has submitted that price escalation was assessed and settled with L&T based on WPI evaluation, considering the extended project timeline. iv. Additional design manhours – Rs. 9.42 Crores:

GHIAL has submitted that L&T incurred additional manhours during execution due to changes in design, resulting in revised architectural, structural and MEP drawings. v. Decrease in scope of works – Rs. (102.07) Crores:

GHIAL has submitted that it revisited material specifications for certain materials used in airside and PTB works, length and breadth of certain civil works and configuration of RETs, i.e., 2 RETs at Code C and 2 RETs at Code E compliant, which resulted in reduction in cost.

b) Megawide Contract – Airport Systems

5.4.7. GHIAL has submitted that the original Megawide contract value, including changes submitted to the Authority during the Third Control Period tariff determination, was Rs. 875.04 Crores. The final cost submitted by GHIAL is Rs. 906.54 Crores, representing an increase of Rs. 31.50 Crores. The increase

comprises: i. Descoping of self-baggage drop and revision to scope of other works amounting to Rs. (32.71) Crores. ii. Claims from Megawide amounting to Rs. 64.21 Crores arising from multiple unforeseen events, including delay in approvals, COVID-19 lockdowns, Russia-Ukraine conflict and impact on supply chain, resulting in price escalations and extension of project timeline from FY2021 to FY2024.

c) Beumer Contract – Airport Systems

5.4.8. GHIAL has submitted that the original Beumer contract value was Rs. 138.32 Crores. The final cost submitted by GHIAL is Rs. 152.48 Crores, representing an increase of Rs. 14.16 Crores on account of prolongation cost due to extended project timelines.

5.4.9. Based on the above, GHIAL has submitted the total capitalisation up to March 31, 2025, for the true-up of the Third Control Period.

5.4.10. GHIAL has submitted independent auditor's certificates on its adopted basis for bifurcation of fixed assets into aeronautical and non-aeronautical assets for the FY22 to FY25.

5.4.11. GHIAL, for the purpose of allocation of assets between aeronautical and non-aeronautical assets for the Third Control Period, has submitted that it has followed the methodology adopted by the Authority as per the Independent Study by CRISIL on Allocation of Assets, which was adopted by the Authority vide Order No. 12/2021-22 for the Third Control Period.

5.4.12. GHIAL has further submitted that the allocation has been carried out after considering changes arising out of implementation of the Hon’ble TDSAT Judgement dated 14.02.2024.

5.4.13. GHIAL has submitted the following supporting documents along with MYTP in support of its asset

allocation methodology: i. Statutory Auditor’s report on allocation of assets from 01.04.2021 to 31.03.2025. ii. Statutory Auditor’s report on retrospective capitalisation of GST on civil portions from 01.04.2017 to 31.03.2024.

iii. Area Allocation Report post 34 MPPA expansion (Annexure 10 to MYTP for 4th Control Period) GHIAL’s submission on Aeronautical Capex

5.4.14. Based on the head-wise capex and the allocation ratios adopted by GHIAL, the aeronautical capex submitted by GHIAL for the true-up of the Third Control Period aggregates to Rs. 6,205.39 Crores as detailed in the table below. The aeronautical portion of the capital expenditure works out to 86.46% of the total capex.

5.4.15. The Authority, at the time of tariff determination for the Third Control Period for GHIAL, had decided the treatment of capital expenditure, asset allocation and depreciation for determination of Aeronautical Regulatory Asset Base (“RAB”) as per Order No. 12/2021-22. The Authority had considered the capital expenditure proposed by GHIAL towards expansion of RGIA to 34 MPPA, general maintenance capital expenditure, metro connectivity, PSF assets and other capital expenditure items to be considered on incurrence basis. Further, since the tariffs were being determined based on 30% shared till, the RAB excluded the portion of assets attributed to the provision of non-aeronautical services. The Authority had accordingly considered only the aeronautical portion of assets for determination of RAB and depreciation for the Third Control Period.

5.4.16. As per the Tariff Order for the Third Control Period, i.e., Order No. 12/2021-22, the Authority, based on the analysis of the capital expenditure plan submitted by GHIAL and findings of the M/s RITES Limited Report, had decided to allow Rs. 4,525.55 Crores (total capex) towards expansion capex, leading to capitalisation of Rs. 4,088.79 Crores in the Third Control Period. Further, the Authority had decided to allow Interest During Construction (“IDC”) of Rs. 436.76 Crores based on prudent means of financing.

Accordingly, the total expansion capex including IDC approved by the Authority for the Third Control Period was Rs. 4,525.55 Crores, i.e. total of Rs. 4088.79 Crores and Rs. 436.76 crores.

5.4.28. In order to examine the above variances, the Authority, through its Independent Consultant, has undertaken a detailed review and due diligence of the actual capital expenditure incurred by GHIAL during the Third Control Period vis a vis the Capital Expenditure allowed by the Authority in the Tariff Order of the Third Control Period.

The review includes examination of the Fixed Asset Register, procurement and bidding processes, project implementation details, capitalisation dates, work orders, invoices, completion certificates, auditor’s certificates and other supporting documentation submitted by GHIAL.

5.4.29. As part of the due diligence exercise, the Independent Consultant has also reviewed the need, essentiality and prudence of the capital expenditure, keeping in view the prevailing and projected traffic demand at RGIA. The assessment includes examination of the expansion works undertaken for enhancement of airport capacity to 34 MPPA, general maintenance capital expenditure, airside and terminal-related works, airport systems, road infrastructure, and other capital expenditure items submitted by GHIAL for true-up.

5.4.30. Further, the Independent Consultant engaged by the Authority examined the technical specifications, execution details and asset capitalisation schedule of the respective projects and assessed the reasonability and justification of the actual expenditure incurred. During site visits undertaken at RGIA, the Independent Consultant reviewed the major capital works executed from the standpoint of operational necessity, essentiality, cost reasonability and capitalisation. The asset category-wise analysis and the Authority’s examination thereof are presented in the following sections.

5.4.31. The Authority notes that GHIAL had submitted capital expenditure of Rs. 5,479.79 Crores towards expansion of RGIA to 34 MPPA. The Authority during the tariff determination exercise of Third Control Period, had engaged M/s RITES Limited as an independent consultant, to examine the scope, size, cost reasonableness of the expansion capex submitted by GHIAL. Based on its examination, M/S RITES LIMITED recommended an amount of Rs.

4,785.86 Crores. Further, after considering the submissions made by GHIAL and the comments received during

Consultation Paper No: 02/2026-27 Page 55 of 308TRUE UP FOR THE THIRD CONTROL PERIOD the stakeholder consultation process, the Authority allowed capitalisation of Rs. 4,525.55 Crores towards the 34 MPPA expansion project for the Third Control Period.

5.4.32. The Authority notes GHIAL’s submission that the expansion project timeline was extended from the original capitalization year of FY21 to actual capitalization year of FY24 on account of COVID-19 lockdowns, supply chain disruptions and other force majeure events, which resulted in additional interest costs during the extended construction period. GHIAL has further submitted that the increase in project cost before IDC from Rs. 5,654.02 Crores to Rs. 5,671.34 Crores required higher debt funding as well as extension of capitalization schedule leading to higher interest expenses, thereby increasing the IDC burden.

5.4.33. Based on the submissions made by the Airport Operator and the decisions taken by the Authority in the Tariff

Order for the Third Control Period, the Authority has decided to analyze the capital expenditure in two parts:

(A) Capital Expenditure towards expansion of RGIA to 34 MPPA; and

(B) General capital expenditure.

5.4.34. The analysis of the same is presented in the following paragraphs.

(A) Capital Expenditure pertaining Expansion to 34 MPPA Compliance with Concession Agreement and Approved Expansion Plan

5.4.35. The Authority notes that RGIA witnessed significant traffic growth during FY17–FY19, rendering the earlier expansion plan to 20 MPPA to be revisited in order to meet the growing demand. Accordingly, GHIAL revised the capacity expansion plan and initiated capacity expansion to 34 MPPA to cater to the growth in traffic in the Third Control Period (FY22–FY26).

5.4.36. The Authority notes that GHIAL had conducted an AUCC meeting on 7th September 2018 apprising the Authority and stakeholders of the overall expansion plan and the requirements therein. The Authority further notes that the expansion project was undertaken in accordance with the Concession Agreement and the development obligations of GHIAL as the airport operator.

5.4.37. The summary of the works executed by GHIAL for the purpose of meeting the 34 MPPA capacity for RGI Airport includes expansion of the passenger terminal building on both eastern and western sides with additional pier expansions, apron expansion on the west-side, construction of new Rapid Exit Taxiways, second parallel Taxiway (Taxiway-B), GSE Tunnel, 8-lane Main Access Road with elevated ramp, and associated airside and landside infrastructure. In total, an additional built-up area of 2,58,089 Sqm has been added to the existing terminal size of 1,21,281 Sqm, resulting in an integrated terminal of 3,79,370 Sqm, thereby increased the design capacity of the terminal building from 20 MPPA to 34 MPPA currently.

Bidding Procedure adopted by GHIAL

5.4.38. The Authority notes that GHIAL had planned the expansion contract management through a mix of independent packages and EPC contracts. In respect of the EPC contracts, GHIAL had invited tenders through International Competitive Bidding (ICB).

5.4.39. Request for Qualification (RFQ) for EPC works was published on 26.09.2017 to obtain Expression of Interest from interested applicants having prior experience in EPC work of similar nature. In response to the RFQ notification, Expressions of Interest were received from four firms:

i. M/s Larsen & Toubro Limited, India

Consultation Paper No: 02/2026-27 Page 56 of 308TRUE UP FOR THE THIRD CONTROL PERIOD ii. M/s Megawide Construction Corporation, Philippines iii. M/s Limak As, Turkey iv. M/s Shapoorji Pallonji & Company Private Limited, India

5.4.40. Based on the evaluation, three bidders namely M/s Larsen & Toubro Limited, M/s Megawide Construction Corporation and M/s Limak As, were pre-qualified to participate in the bidding. Subsequent to the pre- qualification process, GHIAL floated the invitation to tender on 01.12.2017 with the deadline for submission as 15.01.2018. Post pre-bid meeting and subsequent amendments, the final submission date was extended to 22.03.2018.

5.4.41. Tenders were opened on 24.03.2018 for technical evaluation and all bidders were technically qualified, with L&T scoring the highest technical score. The financial bids were opened on 04.07.2018, followed by two rounds of negotiations. At this stage, to optimize project cost and avail input tax credit on supplies under GST, GHIAL identified that the EPC contract can be split into two packages - Airport Systems and all works other than Airport Systems.

5.4.42. The final quotes received from the qualified bidders are summarised below:

Table 24: Final quotes by qualified bidders for 34 MPPA expansion (Rs.

5.4.43. By splitting the contract between L&T and Megawide, GHIAL managed to achieve a saving of Rs. 50.82 Crores compared to the lowest single bidder option. Accordingly, the contracts were awarded as follows:

i. All works other than Airport Systems: Awarded to M/s Larsen & Toubro Limited (L&T) ii. Airport Systems: Awarded to M/s Megawide Construction Corporation (MCSP) and M/s Beumer Group iii. Airside works: Independent package awarded to M/s MVR iv. Road and ramp infrastructure: Independent package awarded to M/s VNC Comparison of Project Cost

5.4.44. The Authority notes that the total expansion capex submitted by GHIAL in the MYTP for the Fourth Control Period amounts to Rs. 5,671.34 Crores (before IDC), as against the cost of Rs. 5,596.23 Crores submitted by GHIAL during the Third Control Period tariff determination and Rs. 4088.79 Crores (before IDC) as approved by the Authority in Order No. 12/2021-22.

5.4.45. The Authority through its Independent Consultant (PwC) has examined the reasons for the escalation in cost over the amount approved in Order No. 12/2021-22. The contract-wise examination is as follows:

L&T Contract (All works other than Airport Systems)

5.4.46. The Authority notes that the original L&T contract value including changes submitted to the Authority during the Third Control Period tariff determination was Rs. 3,063.98 Crores. The final cost of the L&T contract as submitted by GHIAL is Rs. 3,500.70 Crores, representing an increase of Rs. 436.72 Crores. The

Authority through its Independent Consultant has examined the reasons for this increase as follows:

5.4.47. The Authority notes that GHIAL utilized the contingency budget amounting to Rs. 228.11 Crores against the contingency budget of Rs. 243.01 Crores allowed during the Third Control Period submission. The key

works undertaken from the contingency budget include:

Airside Works i. Revised layout of south-east remote apron along with taxilane works ii. Four RETs in compliance to CAT-II requirements (as against CAT-I compliant) iii. Construct additional length of pavement beyond 6M (as per consideration) on either side of GSE Tunnel eastern ramp at North East remote ramp iv. Aviation fuel hydrant system works at west pier v. Additional filling at north-west apron and increase in retaining wall height vi. North West Apron: Due to level increase around 15,000 Sqm of existing rigid apron and flexible pavement was dismantled and reconstructed as per revised levels.

vii. South east taxiway and associated AGL works around 18,000 Sqm area (B2, H1) Electrical Works i. Instead of 5 no.s of 2,000 KVA, GHIAL procured 5 no.s of 2,500 KVA ii. Instead of 2 No. of 3 MVA, GHIAL procured 4 no.s of 2 MVA iii. 3 no.s of Transformers with capacity of 2.5 MVA iv. 3 no.s of 11 KV DG Sets with capacity of 2 MVA v. Electrical load enhancement vi. UPS for IT Equipment vii. Electrical Loads for Advertisement viii. IT Loads ix. Tenant Loads Based on the above changes, the following additional changes were required:

i. Bus Ducts: - 3200A bus duct needs to be upgraded to 4000A ii. Main LT Panels: - Incomer breaker & bus bar needs to be upgraded from 3200A to 4000A current rating iii. APFC Panels: - APFC Panel KVAR rating changed from 2000KVA to 2500KVA

Consultation Paper No: 02/2026-27 Page 59 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.4.48. This also considers all required and associated works like Bus Duct, HT cable, LT cable, HT panel, LT panel, Sub LT panel, Cable Tray, and earthing works. Further, the overall connected load increased from

14.8 MW to 37.6 MW.

Grid Change i. The existing Passenger Terminal Building was designed on a 9m x 9m structural grid, and the original tender drawings were also based on these dimensions. During execution, the structural grid was revised to 18m x 18m and 18m x 36m configurations. This change in grid dimensions had consequential impacts across multiple work packages including concrete works, shuttering, rebar, structural steel, façade systems, electrical works, HVAC ducting, and necessitated the provision of additional cable trenches in the apron area in lieu of routing through the bottom of the First Level Beam (FLB).Grid changes in the terminal building from 9m x 9m to 18m x 18m and 18m x 36m grids.

Other Items i. Enhancement of Front-of-House (FOH) toilet specifications and FOH false ceiling works in the arrival areas at E-level and C-level of the East and West Piers and D-level of the East and West Processor buildings, along with all counters (excluding gate portals), as per the revised Woods Baggot concept design;

ii. Increase in the overall toilet areas across the terminal; iii. Increase in the areas allocated for warehouse, office, SPS and STP office facilities; iv. Increase in the First Level Beam (FLB) area and enhancement of FLB glass thickness; and v. Enhancements in lighting specifications across the terminal in comparison to the original design specifications.

5.4.49. With respect to utilisation of the contingency budget amounting to Rs. 228.11 Crores, the Authority notes that the works undertaken from the contingency budget included, inter alia, the following:

• Revised layout of the south-east remote apron; • Four Rapid Exit Taxiways (“RETs”) in compliance with CAT-II requirements; • Aviation fuel hydrant system works; • Electrical load enhancement from 14.8 MW to 37.6 MW;

• Structural grid changes in the terminal building; • Façade modifications; • Enhancement in toilet specifications; and • Changes in lighting and other design requirements.

5.4.50. The Authority notes that these works were necessitated by operational requirements, regulatory compliance and design optimisation during execution of the brownfield expansion project. The Authority is of the view that such modifications are not uncommon in projects of this scale and complexity. Further, the utilisation of the contingency budget has remained within the originally provisioned amount of Rs. 243.01 Crores.

Consultation Paper No: 02/2026-27 Page 60 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.4.51. The Authority notes that the L&T contract cost has increased primarily on account of extended stay cost, price escalation, additional design manhours and utilisation of contingency budget. The key reasons for such increase, as submitted by GHIAL, are as follows:

• Extended stay cost of Rs. 112.10 Crores; • Price escalation of Rs. 76.70 Crores based on WPI evaluation; • Additional design manhours of Rs. 9.42 Crores; and • Utilisation of contingency budget amounting to Rs. 228.11 Crores against the provision of Rs.

243.01 Crores.

5.4.52. The Authority notes that the extended stay cost of Rs. 112.10 Crores was attributable to the extension of the project timeline for the terminal building from the original planned completion, i.e., FY2021, to FY2024.

The extension was on account of multiple unforeseen events, including COVID-19 lockdowns and restrictions, logistics disruptions and manpower exodus. The Authority is of the view that these events were largely beyond the control of GHIAL and were force majeure in nature. Accordingly, the resultant cost impact on the project appears to be unavoidable.

5.4.53. The Authority further notes that the price escalation of Rs. 76.70 Crores was assessed and settled based on Wholesale Price Index (“WPI”) evaluation. The Authority considers WPI-based escalation to be a transparent and generally accepted methodology for computation of escalation in construction contracts.

Therefore, the Authority is of the view that the price escalation has been computed on a reasonable basis and reflects the inflationary impact during the extended project duration.

5.4.54. The Authority also notes that GHIAL has submitted additional design manhours of Rs. 9.42 Crores on account of changes in architectural, structural and MEP drawings. These changes were consequent to the design modifications and scope changes undertaken during execution. The Authority is of the view that such costs are directly attributable to the approved scope changes and appear to be reasonable.

5.4.55. Further, the Authority notes that GHIAL has also accounted for a reduction in cost of Rs. 102.07 Crores on account of decrease in scope of works. The reduction is attributable to revision in material specifications, changes in dimensions of certain civil works and reconfiguration of Rapid Exit Taxiways. The Authority notes that the said reduction has partially offset the overall cost escalations in the L&T contract.

5.4.56. Based on the above examination, the Authority is of the view that the cost escalations towards the L&T contract are attributable to factors that were largely beyond the control of GHIAL, including the impact of COVID-19, force majeure events, regulatory compliance requirements and design optimisation necessitated during execution of the brownfield expansion project. The Authority has also compared the actual cost incurred by GHIAL with the normative cost benchmarks and notes that the actual cost falls within the parameters of the normative cost. Accordingly, the Authority is of the view that the final L&T contract cost of Rs. 3,500.70 Crores as submitted by GHIAL is reasonable and efficient, and proposes to consider the same for the purpose of true-up of the Third Control Period.

(ii) Megawide Contract (Airport Systems) Table 27: Break-up of cost variations in Megawide Contract (Rs. In crores) Particulars Ref Amount EPC Contract awarded through tender including changes submitted during the 3rd CP A 875.04

5.4.57. The Authority notes that during the execution of the Airport Systems contract, GHIAL had undertaken a descoping exercise amounting to Rs. (32.71) Crores which included descoping of Self-Baggage Drops, revision in scope of PBB Tunnels, Ground Power Unit Converters and Hatch Pits, Pre-Conditioned Air Units, Screening Machines and VDGS. Simultaneously, the scope of works was increased in respect of CTX Screening Machines and Automated Tray Retrieval Systems, BHS Equipment and Pre-Conditioned Air Units and Ground Power Units proposed to be attached to the Passenger Boarding Bridges. The Authority is of the view that the descoping and scope enhancements were undertaken based on evolving design requirements and operational considerations during the course of execution.

5.4.58. The Authority further notes that multiple unforeseen events - including delays in approvals from various authorities, multiple lockdowns due to COVID-19 and associated bans, the Russia-Ukraine conflict and its impact on global supply chains and logistics - resulted in price escalations and extension of the project timeline from the originally planned completion in FY2021 to FY2024. These events, which were beyond the control of GHIAL, resulted in multiple claims from Megawide amounting to Rs. 64.21 Crores. The Authority noted that these claims were settled after careful evaluation and multiple rounds of negotiations by March 2025.

5.4.59. The Authority is of the view that the events leading to the claims were force majeure in nature and the resultant cost impact was unavoidable. The Authority is of the view that GHIAL has exercised due diligence in evaluating and negotiating the claims and the settlement amount of Rs. 64.21 Crores is reasonable.

Accordingly, the Authority proposes to consider the final Megawide contract cost of Rs. 906.54 Crores as submitted by GHIAL for the purpose of true-up of the Third Control Period.

(iii) Beumer Contract (Airport Systems)

5.4.60. The Authority notes that the original Beumer contract value was Rs. 138.32 Crores. The final cost is Rs.

152.48 Crores, an increase of Rs. 14.16 Crores on account of prolongation cost due to extended project timelines.

Table 28: Break-up of cost variations in Beumer Contract (Rs. In crores) Particulars Ref Amount EPC Contract awarded through tender A 138.32 Prolongation Cost B 14.16 Total cost for Airport Systems to Beumer (C = A + B) C 152.48

5.4.61. The Authority notes that the prolongation cost was attributable to the extension of the project timelines which was consequential to the overall delay in the 34 MPPA expansion project caused by COVID-19 lockdowns, supply chain disruptions and other force majeure events. The Authority is of the view that since the Beumer contract for Airport Systems was interlinked with the overall expansion project timeline, the prolongation cost arising from the extended project duration was unavoidable and beyond the control of GHIAL. Accordingly, the Authority is of the view that the prolongation cost of Rs. 14.16 Crores is reasonable and proposes to consider the final Beumer contract cost of Rs. 152.48 Crores as submitted by GHIAL for the purpose of true-up of the Third Control Period.

Consultation Paper No: 02/2026-27 Page 62 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

(iv) MVR and VNC Contracts

5.4.61. The Authority notes that the MVR contract for airside works was at Rs. 142.70 Crores, which was the same as the original contract value submitted during the Third Control Period. The VNC contract for road and ramp infrastructure was at Rs. 228.67 Crores as against Rs. 229.99 Crores submitted during the Third Control Period, representing a decrease of Rs. 1.32 Crores.

5.4.62. Accordingly, the summary of vendor wise Cost submitted by GHIAL is as follows:

Table 29: Summary of Contract Awarded for 34 MPPA Expansion as submitted by GHIAL (Rs. In crores) Particulars L&T MCSP MVR VNC Beumer Others Total Expansion of the Terminal Building 2,753.80 - - - - 162.23 2,916.03 including Piers Airport Systems - 906.54 - - 152.48 82.77 1,141.80 Expansion of Apron & Taxiways,

5.4.63. Further, the Authority had sought confirmation from GHIAL regarding the amount capitalized during FY 2026 against the proposed CWIP of ₹43.95 crore and amount of ₹234.10 crore carry forwarded from FY 25 to FY 26, which were earlier proposed to be capitalized in FY 2026.

5.4.64. In its revised submission, GHIAL has informed that an amount of Rs. 107.07 crore has been capitalized during FY 2026 and further, GHIAL has submitted that, as on 31 March 2026, the balance uncapitalized

amount comprises:

Table 30: Uncapitalized Balance by GHIAL Particulars Amount (₹ crore) CWIP as on 31.03.2026 92.53 Carry-forward as on 31.03.2026 75.97 Total balance not capitalized in FY 2026 168.50

5.4.65. GHIAL has further submitted that the above balance amount of ₹168.50 crore is expected to be capitalized in FY 2027.

5.4.66. Based on the submission made by GHIAL, the Authority has considered and allowed capitalization of only ₹107.07 crore during FY 2026, being the amount actually capitalized during the year. The remaining amount of ₹168.50 crore, comprising CWIP of ₹92.53 crore and carry-forward amount of ₹75.97 crore as on 31 March 2026, has not been considered for capitalization in FY 2026, since the same has not been capitalized/put to use during the year.

5.4.67. Accordingly, the Authority has deferred/shifted the remaining amount of Rs. 168.50 Crores to FY 2027 (i.e.

1st tariff year of the 4th Control Period) which includes Rs. 152.59 Crores towards hard cost, and Rs. 15.92 Crores pertaining to soft cost.

5.4.68. Accordingly, hard cost proposed to be considered by the Authority is as follows:

Consultation Paper No: 02/2026-27 Page 63 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Table 31: Hard Cost proposed to be considered by the Authority for True Up of the Third Control Period (Rs. In Crores) Particulars Amount Hard Cost regarding expansion to 34 MPPA project submitted by GHIAL (A) 5,380.43 Hard Cost deferred from Third Control Period to Fourth Control Period (B) 152.59 Hard Costs proposed to be considered by the Authority (C=A-B) 5,227.84 Soft Costs (PMC, Insurance, Preliminaries)

5.4.69. The Authority notes that at the time of tariff determination for the Third Control Period, M/s RITES Limited (Independent Capex Consultant) had recommended the following soft costs: i. Preliminaries, Insurance & Permits: Rs. 98.35 Crores (against GHIAL's submission of Rs. 120.20 Crores) ii. Design Development and PMC: Rs. 132.67 Crores (against GHIAL's submission of Rs. 202.94 Crores). M/S RITES LIMITED had noted that the PMC of Rs. 154.92 Crores had been awarded by GHIAL to its own group company GADL without any competition and had recommended reducing the PMC & Design fee to 3% of the hard cost.

iii. Contingencies: Rs. 132.67 Crores at 3% of hard cost (against GHIAL's submission of Rs. 243.01 Crores at 4.83% of hard cost)

5.4.70. The Authority notes that GHIAL has now submitted the following actual soft costs in the MYTP for the

Fourth Control Period: i. Preliminaries: Rs. 18.33 Crores ii. Insurance & Permits: Rs. 19.18 Crores iii. Design Development and PMC: Rs. 253.40 Crores iv. Contingencies: Rs. 0.00 Crores (fully utilised towards new works as described above)

5.4.71. The Authority notes that while the Preliminaries and Insurance & Permits at Rs. 37.51 Crores are significantly lower than the RITES-approved cost of Rs. 98.35 Crores, the Design Development and PMC cost at Rs. 253.40 Crores is significantly higher than the M/s RITES Limited-approved cost of Rs. 132.67 Crores. The contingency budget has been fully utilised towards new works awarded during execution.

5.4.72. With respect to Preliminaries and Insurance & Permits, the Authority notes that the actual cost submitted by GHIAL is Rs. 37.51 Crores, comprising Preliminaries of Rs. 18.33 Crores and Insurance & Permits of Rs. 19.18 Crores. The Authority notes that the said cost is significantly lower than the M/s RITES Limited- approved cost of Rs. 98.35 Crores considered in Order No. 12/2021-22. The Authority is of the view that GHIAL has demonstrated efficiency in managing the preliminary and insurance costs. However, the Authority also notes that out of the Preliminaries cost, an amount of Rs. 0.08 Crores remains under CWIP and Rs. 1.48 Crores has been carried forward as on 31.03.2026. Accordingly, these amounts aggregating to Rs. 1.56 Crores are not considered for capitalization during FY 2026 / Third Control Period and are proposed to be deferred for consideration in FY 2027, as per the submission of the airport operator.

Consequently, the Authority proposes to consider Rs. 35.95 Crores for Preliminaries and Insurance & Permits.

Consultation Paper No: 02/2026-27 Page 64 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.4.73. With respect to Design Development and PMC, the Authority notes that M/s RITES Limited had recommended a cost of Rs. 132.67 Crores in the Tariff Order for the Third Control Period. The Authority notes that at the time of the tariff determination for the Third Control Period, M/s RITES Limited had recommended restricting the soft cost, including PMC and Design fee, to 3% of the hard cost on the grounds that the PMC had been awarded by GHIAL to its group company, GADL, without competitive bidding.

5.4.74. The Authority notes that the actual hard cost of the expansion project proposed to be considered by the Authority is Rs. 5,227.84 Crores. In line with the approach adopted by RITES during the Third Control Period tariff determination, the Authority proposes to restrict the soft cost, including Design Development and PMC, to 3% of the actual hard cost. Accordingly, the allowable Design Development and PMC cost works out to Rs. 156.84 Crores as against the Design Development and PMC cost of Rs. 253.40 Crores submitted by GHIAL. The Authority therefore proposes not to deviate from the stand taken during the tariff determination for the Third Control Period and restrict the Design Development and PMC cost to Rs. 156.84 Crores for the purpose of true-up of the Third Control Period. Further, the amount remaining under CWIP amounting to Rs. 14.36 Crores as on 31.03.2026 shall not be considered for capitalization during Third Control Period and may be considered in FY2027, subject to actual capitalization and prudence check.

5.4.75. With respect to Contingencies, the Authority notes that the contingency budget of Rs. 243.01 Crores has been fully utilised towards new works awarded during execution as detailed in the preceding paragraphs, and no separate contingency amount has been claimed by GHIAL under soft cost. Further, no amount under Contingencies has been reported as CWIP or carry-forward as on 31.03.2026. The Authority is of the view that the contingency budget has been utilized towards works that were necessitated by operational requirements and design optimization during the course of the brownfield expansion.

5.4.76. The Authority notes that, as per the status submitted by GHIAL as on 31.03.2026, the following soft cost amounts remain either under CWIP or have been carried forward and are proposed to be capitalized in FY 2027:

Table 32: Summary of works pertaining to Soft Cost considered as CWIP/ Carry Forwarded to the Fourth Control Period (Rs. In Crores) Total CWIP as on Carry-forward as on Particulars (not considered in FY

5.4.77. Accordingly, against the total soft cost of Rs. 290.91 Crores submitted by GHIAL, the Authority proposes to consider Rs. 178.43 Crores for the purpose of true-up of the Third Control Period. The variation in the

soft cost is due to the following: • Disallowance of Rs. 96.56 Crores in Design Development and PMC as mentioned in para 5.4.74 above • Carry Forward of soft cost amounting to Rs. 15.92 Crores as per Table 32.

Consultation Paper No: 02/2026-27 Page 65 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Hence, the Authority has considered Rs. 178.43 Crores as soft costs for true up of the Third Control Period,

as given in the table below:

Table 33: Soft Cost proposed to be considered by the Authority for true up of the Third Control Period (Rs. Crores) Total Soft Cost as Total Soft Cost proposed to be Particulars submitted by GHIAL considered by the Authority Soft Costs 290.91 178.43 Interest During Construction (IDC)

5.4.78. The Authority notes that GHIAL has submitted IDC of Rs. 1,285.40 Crores as capitalized till March 2025 in the MYTP for the Fourth Control Period. This is significantly higher than the IDC of Rs. 436.76 Crores approved by the Authority in Order No. 12/2021-22. Further, pursuant to clarifications sought by the Authority, GHIAL clarified that the IDC amount considered for the purpose of calculation of tariff determination is Rs. 1,506.17 Crores. The details pertaining to IDC have been dealt with in the subsequent paragraphs.

5.4.79. The Authority noted that the means of finance for the expansion project as submitted by GHIAL was 70% Debt and 30% Internal Accruals.

5.4.80. The Authority notes that GHIAL funded the expansion project through a combination of Senior Secured Notes (SSN) denominated in USD and Non-Convertible Debentures (NCD) denominated in INR. The

summary of debt instruments utilised by GHIAL for the expansion project is as follows:

Table 34: Summary of Debt Instruments used by GHIAL for the Expansion Project Coupon All-in Cost Sr. Date of Nature of Instrument Amount Rate (INR Tenure No. Drawdown Hedging

Source: Annexure 5 — IDC, GHIAL MYTP for the Fourth Control Period

5.4.81. The Authority notes that the all-in cost of borrowing (inclusive of coupon interest, hedge premium and withholding taxes) ranged from 8.65% to 9.958% (INR equivalent) for the USD borrowings. The Authority further notes that GHIAL undertook a refinancing exercise in December 2022 and March 2023, whereby portions of the USD 300 Mn @ 5.375% and USD 300 Mn @ 4.75% borrowings were refinanced through domestic INR NCDs at coupon rates of 8.805% and 8.71% respectively. The Authority is of the view that this refinancing was a prudent measure undertaken by GHIAL to reduce the overall cost of borrowing. The Authority notes that all USD borrowings were hedged through recognised market instruments - Cross Currency Swaps and Call Spread Options with Coupon Only Swaps - to mitigate foreign exchange risk.

Consultation Paper No: 02/2026-27 Page 66 of 308TRUE UP FOR THE THIRD CONTROL PERIOD The Authority is of the view that the hedging strategy adopted by GHIAL is in line with prudent treasury management practices.

5.4.82. Further, the Authority notes that GHIAL has adopted the following methodology for computing IDC:

Table 35: IDC Computation Methodology adopted by GHIAL for the Fourth Control Period (Rs. In crores) Step Particulars Amount A Interest cost on total borrowings drawn 3,018.35

B Less: Interest cost pertaining to borrowings not utilised for the project purpose (1,085.36)

C Less: Interest cost subsequent to capitalisation of assets (475.47) D Net Interest Cost Capitalised (A − B − C) 1,457.53

E Add: Financing costs capitalised (arrangement fees, processing charges) 48.64 F Total IDC (D + E) 1,506.17

5.4.83. The Authority is of the view that the methodology adopted by GHIAL for computing IDC is transparent and consistent with the applicable accounting standards. GHIAL has correctly excluded: i. Interest cost pertaining to borrowings not utilised for the project purpose (Rs. 1,085.36 Crores), thereby ensuring that only the interest cost attributable to project borrowings has been capitalised; and ii. Interest cost subsequent to capitalisation of assets (Rs. 475.47 Crores), ensuring that IDC is not charged post-commissioning of the respective assets.

5.4.84. Furthermore, the year-wise IDC computation as submitted by GHIAL is presented below:

Table 36: Year-wise IDC Computation as submitted by GHIAL for the Third Control Period (Rs. In crores) Particulars FY18 FY19 FY20 FY21 FY22 FY23 FY24 Total Interest Cost on total borrowings 85.04 199.07 407.15 445.89 624.04 627.01 630.14 3,018.35 drawn (A)

5.4.85. The Authority notes that for the purpose of the Third Control Period true-up, only the IDC capitalised during the Third Control Period is relevant. The IDC capitalisation schedule as submitted by GHIAL is as

follows:

Consultation Paper No: 02/2026-27 Page 67 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Table 37: IDC Capitalisation Schedule as submitted by GHIAL (Rs. In crores) Particulars FY18 FY19 FY20 FY21 FY22 FY23 FY24 FY25 FY26 Total IDC Capitalised 0.00 10.68 35.94 0.00 35.14 454.90 969.51 0.00 0.00 1,506.17

Of which: 2nd CP (FY 17-

Of which: 3rd CP (FY 21-

35.14 454.90 969.51 0.00 0.00 1,459.55 22 to FY 25-26)

5.4.86. The Authority notes that the total IDC of Rs. 1,506.17 Crores pertains to the entire project period spanning FY 2017-18 to FY 2023-24. Of this: i. IDC of Rs. 46.62 Crores was capitalised during the Second Control Period (Rs. 10.68 Crores in FY 18-19 and Rs. 35.94 Crores in FY 19-20); and ii. IDC of Rs. 1,459.55 Crores was capitalised during the Third Control Period (Rs. 35.14 Crores in FY 21-22, Rs. 454.90 Crores in FY 22-23 and Rs. 969.51 Crores in FY 23-24).

5.4.87. The Authority noted that the IDC capitalised during the Second Control Period (Rs. 46.62 Crores) pertains to the assets that were capitalised during FY 18-19 and FY 19-20 (i.e., the Kerb & Approach Ramp and parking stands that were completed ahead of the main expansion works). The IDC attributable to these assets was duly capitalised in the Second Control Period and would have been considered as part of the Second Control Period true-up. Accordingly, for the purpose of the Third Control Period true-up, the Authority proposes to consider only the IDC capitalized during FY 2021-22 to FY 2025-26 amounting to Rs. 1,459.55 Crores, which corresponds to the expansion assets capitalised during the Third Control Period.

5.4.88. The Authority notes that the IDC of Rs. 436.76 Crores approved in Order No. 12/2021-22 was computed based on the approved project cost and the assumption that the project would be completed within the originally envisaged timeline. The actual IDC capitalised in the Third Control Period at Rs. 1,459.55 Crores is significantly higher. The Authority noted the following reasons for the increase:

Table 38: Reasons for increase in IDC over the approved amount for the Third Control Period Sr.

Factor Impact No.

1 Extension of project timeline from FY2021 to FY2024 due to Approximately 3 additional years of interest COVID-19 lockdowns, supply chain disruptions and force majeure costs during construction events 2 Increase in overall project cost from approved Rs. 4,820.05 Crores Higher debt quantum required to fund the (before IDC) to actual Rs. 5,671.34 Crores (before IDC) increased project cost 3 All-in hedged cost of USD borrowings (8.65% to 9.958%) inclusive Higher than the base coupon rate assumed in of coupon, hedge premium and withholding taxes the original IDC computation 4 Financing costs (arrangement fees, processing charges) of Rs. 48.64 Standard costs associated with capital market Crores borrowings capitalised as part of IDC

5.4.89. Further, the Authority notes that, based on the prudence check of the capital expenditure proposed for the Expansion to 34 MPPA project, the allowable capital cost, excluding IDC, has been assessed at Rs. 5,406.27 Crores as against Rs. 5,671.34 Crores submitted by GHIAL, as detailed in Table 40. Accordingly, the reduction in capital expenditure works out to Rs. 265.07 Crores, representing 4.67% of the capital expenditure, excluding IDC, submitted by GHIAL. The Authority further notes that GHIAL has submitted IDC of Rs. 1,459.55 Crores in respect of the said project, as detailed in Table 37. Since IDC is incidental

Consultation Paper No: 02/2026-27 Page 68 of 308TRUE UP FOR THE THIRD CONTROL PERIOD to, and arises from, the underlying capital expenditure, the Authority is of the view that IDC should be allowed only to the extent it is attributable to the capital cost found reasonable and efficient after prudence check. Accordingly, the Authority has proportionately disallowed IDC to the extent of 4.67%, in line with the disallowance made in the underlying capital expenditure. The proportionate IDC disallowance works out to Rs. 68.22 Crores.

5.4.90. Based on the above examination, the Authority is of the view that: i. The debt instruments used by GHIAL for funding the expansion project are from recognized capital market sources and the borrowing rates are reflective of the prevailing market conditions at the time of issuance;

ii. GHIAL's refinancing of a portion of higher-cost USD borrowings through domestic INR NCDs at lower rates demonstrates prudent treasury management; iii. The IDC computation methodology adopted by GHIAL is transparent, with proper netting-off of interest on borrowings not utilised for the project and interest subsequent to capitalisation of assets;

iv. The increase in IDC over the approved amount is a direct consequence of the extension of the project timeline and increase in project cost, both of which have been examined and accepted by the Authority in the preceding paragraphs; and v. The financing costs of Rs. 48.64 Crores are in the nature of arrangement fees and processing charges which are standard costs associated with capital market borrowings.

5.4.91. Accordingly, the Authority proposes to consider IDC of Rs. 1,459.55 Crores for the Third Control Period, being the IDC capitalised during FY 2021-22 to FY 2023-24 as per the capitalisation schedule submitted by GHIAL. The IDC of Rs. 46.62 Crores capitalised during the Second Control Period has been considered as part of the Second Control Period true-up and is not being double-counted. Further, IDC amounting to Rs. 68.22 Crores has been deducted from the IDC on proportionate basis.

Table 39: Summary of IDC proposed to be considered by the Authority for the Third Control Period (Rs. In crores) Particulars Amount IDC approved in Order No. 12/2021-22 for the Third Control Period 436.76 Total IDC as per GHIAL (entire project period FY 17-18 to FY 23-24) 1,506.17

Less: IDC reduced on proportionate basis (68.22) IDC proposed to be considered for the Third Control Period 1,391.33 GST Input Tax Credit

5.4.92. The Authority notes that GHIAL has submitted GST Input Tax Credit of Rs. 323.79 Crores on Plant & Machinery as part of the expansion capex capitalization.

5.4.93. The Authority notes that the GST ITC has been duly verified by the Statutory Auditors of GHIAL as part of the Statutory Auditor's report on retrospective capitalisation of GST on Civil Portions from 01.04.2017 to 31.03.2024 submitted along with the MYTP.

5.4.94. The Authority proposes to consider the GST ITC of Rs. 323.79 Crores as submitted by GHIAL for the purpose of determining the net capitalisation towards the expansion project.

Consultation Paper No: 02/2026-27 Page 69 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.4.95. The retrospective capitalisation relating to GST input amounting to Rs. 129.85 Crores, for the period prior to the Third Control Period has been considered as part of the opening RAB for the Third Control Period, since the claim for the same has been submitted as part of the true-up for the Third Control Period.

Capital Work in Progress (CWIP) and Carry Forwards

5.4.96. The Authority notes that as per GHIAL's submission, Rs. 43.95 Crores remains as Capital Work in Progress as on March 31, 2025 and a total carry forward of Rs. 234.10 Crores is yet to be incurred/capitalised.

Accordingly, the total amount pending for capitalisation/incurrence works out to Rs. 278.05 Crores as on March 31, 2025.

5.4.97. The Authority further notes that the pending works primarily pertain to Road Infrastructure (Rs. 135.37 Crores carry forward), Airport Systems (Rs. 28.92 Crores carry forward) and Apron & Taxiways (Rs. 40.35 Crores carry forward) and the same has not been considered for aeronautical asset allocation for the Third Control period.

(B) Examination of General Maintenance Capital Expenditure for the Third Control Period General Capex approved vs Actual

5.4.99. The Authority in Order No. 12/2021-22 for the Third Control Period had approved the following general

maintenance capital expenditure: i. Airfield pavement enhancement and airfield ground lighting upgrade: Capitalisation of Rs. 308.56 Crores ii. General and allied capital works: Rs. 1,256.67 Crores

5.4.100. The Authority has examined the general capex incurred and capitalised by GHIAL during the Third Control Period vis-à-vis the capital expenditure approved in Order No. 12/2021-22. The Authority notes that against the approved general maintenance capital expenditure of Rs. 1,565.23 Crores, GHIAL has submitted actual capitalisation of Rs. 1,483.89 Crores for the Third Control Period. The Authority further notes that the general capex submitted by GHIAL is lower than the overall amount approved by the Authority for the Third Control Period and has been incurred towards airfield pavement enhancement, airfield ground

Consultation Paper No: 02/2026-27 Page 70 of 308TRUE UP FOR THE THIRD CONTROL PERIOD lighting upgrade, general and allied capital works, maintenance, replacement and upgradation of airport facilities.

5.4.101. The Authority, based on its examination, is of the view that the general capex incurred by GHIAL during the Third Control Period is in line with the operational requirements of RGIA and is necessary for maintaining service quality, safety, reliability and operational efficiency of the airport. Accordingly, the Authority proposes to consider the general capex of Rs. 1,483.89 Crores as submitted by GHIAL for the purpose of true up of the Third Control Period.

5.4.102. The year-wise comparison of the approved general capex, the general capex submitted by GHIAL, and the

general capex proposed to be considered by the Authority is provided in the table below:

Table 41: General Capex approved by the Authority vs actual incurred by GHIAL in the Third Control Period (Rs. In crores) FY ending March 2022 2023 2024 2025 2026 Total Approved by the Authority in Order

5.4.103. The Authority notes that the general capex submitted by GHIAL for the Third Control Period forms part of the overall capitalisation considered for true up of the Third Control Period. The Authority further notes that, for the purpose of determination of additions to RAB, the general capex has been considered together with the expansion capex and other capital additions after carrying out the necessary asset classification and allocation between aeronautical, non-aeronautical and common assets in Fixed Asset Register.

Accordingly, the general capex is subsumed within the overall capex proposed to be considered by the Authority, and the total capex allowed for the Third Control Period shall be as per Table 40: Project cost for 34 MPPA Expansion proposed to be considered by the Authority for the Third Control Period.

5.4.104. Based on the above, the total expansion capex proposed to be considered by the Authority works out to Rs.

Consultation Paper No: 02/2026-27 Page 71 of 308TRUE UP FOR THE THIRD CONTROL PERIOD decided by the Authority in Order No. 12/2021-22. The principles adopted for segregation of assets are as

follows: i. Aeronautical Assets: Assets which are necessary or required for providing the aeronautical services at the airport and all such assets that GHIAL may procure in accordance with directions of GoI for or in relation to provision of any of the reserved activities. Assets directly related to the aeronautical services include runways, taxiways, aprons, airfield ground lighting, navigational aids, airside roads and related infrastructure.

ii. Non-Aeronautical Assets: Assets which are necessary for the performance of non-aeronautical services at the airport, including commercial concessions, advertising spaces, car parking infrastructure, and other revenue-generating assets not directly linked to aeronautical services.

iii. Common Assets: Assets which are not identifiable/ categorized into either aeronautical or non- aeronautical assets. These include the passenger terminal building (allocated using Terminal Area Ratio), site offices, new office building, common hardware, software and communication systems.

Table 43: Comparison of Regulatory Asset Base treatment for the Third Control Period GHIAL in MYTP is a vis treatment of assets proposed to be considered by the Authority Treatment by GHIAL as per the Fourth Treatment of assets proposed to be Allocation Control Period MYTP considered by the Authority Non Aeronautical (in line with TDSAT CGF, ICT, GPU Aeronautical Judgement) New Office Building 100% Common 60% Non-Aero, 40% Common

5.4.106. The methodology for allocation ratios adopted by the Authority in the Tariff Order of the Third Control Period has been considered for the purpose of True Up of the Third Control period by taking into

consideration the following: i. Each asset has been identified and verified from the Fixed Asset Register and classified into Aeronautical, Non Aeronautical and Common categories based on its nature and utility. Further, certain capital assets which are common in nature have subsequently been allocated between Aeronautical and Non Aeronautical activities on the basis of Aeronautical Gross Block for individual years.

ii. Assets related to the passenger terminal building have been apportioned between aeronautical and non-aeronautical assets using the Terminal Area Ratio of 84.6% (Aero) and 15.4% (Non-Aero) as adopted in the Third Control Period Tariff Order.

iii. Re-computation of Gross Fixed Asset Ratio for apportionment of common assets pertaining to assets other than the terminal building. The variation between the ratio submitted by GHIAL and the ratio proposed by the Authority is primarily on account of reclassification of certain assets based on AERA principles, including treatment of Cargo, Ground Handling and Fuel Farm (“CGF”) assets. While GHIAL has treated CGF assets as non-aeronautical, the Authority has continued to treat the same as

Consultation Paper No: 02/2026-27 Page 72 of 308TRUE UP FOR THE THIRD CONTROL PERIOD aeronautical in line with the treatment adopted in the previous Tariff Orders. Accordingly, the Gross

Fixed Asset Ratio proposed by the Authority is as follows:

Table 44: GFA proposed to be considered by the Authority for True up of the Third Control Period FY ending March FY22 FY23 FY24 FY25 FY26 GFA Ratio as submitted by GHIAL 88.16% 89.06% 88.29% 88.21% 87.03% GFA Ratio proposed by authority 91.24% 90.02% 88.92% 88.85% 88.77%

5.4.107. Accordingly, year-wise asset capitalization proposed to be considered by the authority after applying the

relevant aeronautical ratios is as follows:

5.4.114. GHIAL has computed depreciation for the assets based on the useful life of assets as per the Companies Act or the concession period, whichever is lower, consistent with Order No. 35/2017-18. The major asset category-wise useful life considered by GHIAL and proposed to be considered by the Authority is as

follows:

5.4.115. The Authority through its Independent Consultant (PwC) has examined the depreciation submitted by GHIAL for the Third Control Period based on the Fixed Asset Register. The Authority notes that the

Consultation Paper No: 02/2026-27 Page 74 of 308TRUE UP FOR THE THIRD CONTROL PERIOD depreciation has been recomputed after carrying out a detailed review of the assets capitalised during the Third Control Period and after reclassifying the assets into aeronautical, non-aeronautical and common categories in accordance with the principles adopted by the Authority in the previous Tariff Orders. For assets directly identifiable with aeronautical services, the depreciation has been considered fully under aeronautical depreciation. In respect of common assets, the depreciation has been apportioned based on the applicable allocation ratios, including the Terminal Area Ratio for terminal-related common assets and the Gross Fixed Asset Ratio for other common assets. Accordingly, the aeronautical portion of depreciation has been computed for the purpose of true up of RAB and ARR for the Third Control Period, subject to reasonableness and consistency with the applicable depreciation rates and asset classification principles.

5.4.116. The Authority notes that there were certain line items in the Fixed Asset Register where GHIAL had depreciated the entire remaining depreciable value of the asset, despite the useful life of such assets not being fully exhausted. The asset classes in which such accelerated depreciation was claimed by GHIAL included Buildings, Other Roads, and Plant & Machinery. Further, in respect of assets capitalised during the middle of the year, GHIAL had considered depreciation for the full year. The Authority has recomputed depreciation on a pro-rata basis from the date of capitalisation of the respective assets, in line with the principle that depreciation should be allowed only from the date on which the asset is capitalised and put to use.

5.4.117. The Authority notes that Advance Development Fund Grant (“ADFG”) has been considered as a grant for the purpose of regulatory tariff determination. Since assets funded through grant are not funded by the Airport Operator, the cost of such assets is not required to be recovered from airport users through aeronautical tariffs.

5.4.118. Accordingly, the Authority has reduced the amount of ADFG from the aeronautical RAB. Consequent to such reduction, depreciation attributable to the ADFG-funded portion of assets is also required to be excluded from the depreciation considered for tariff determination. Therefore, the depreciation corresponding to the ADFG-funded assets has been reduced from the total aeronautical depreciation.

5.4.119. The Authority is of the view that allowing depreciation on assets funded through ADFG would result in recovery of cost not incurred by the Airport Operator and would therefore not be appropriate from a regulatory perspective. Accordingly, the ADFG adjustment has been considered as a reduction from depreciation for the purpose of computation of ARR for the relevant Control Period.

5.4.120. The Authority, based on the adjustments and disallowances in the aeronautical asset additions to RAB in

the Third Control Period proposes to consider proportionate adjustment in depreciation as follows:

Table 50: Depreciation proposed to be considered by the Authority for true up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Depreciation on Aero RAB 179.92 223.69 320.27 420.77 406.49 1551.14 ADFG Adjustment 5.17 4.42 4.69 5.16 5.23 24.67 Depreciation (incl.

5.4.121. Considering the above, the Regulatory Asset Base for true up of the Third Control Period as submitted by

GHIAL is given in the table below:

5.4.124. The Authority through its Independent Consultant (PwC) examined the asset deletions for the Third Control Period based on the analysis of the Fixed Asset Register. The Authority notes that the deletions proposed to be considered have been arrived after examination of the Fixed Asset Register and reclassification of assets as per AERA principles. The variation between the deletions submitted by GHIAL and the deletions proposed by the Authority is mainly on account of reclassification of assets between aeronautical, non- aeronautical and common categories based on the principles adopted by the Authority in previous Tariff Orders. The adjustments proposed are as follows:

5.5.5 The Authority notes that the actual effective cost of debt for FY 2025-26 submitted by GHIAL works out to 8.88%, as against the projected effective cost of debt of 9.97% submitted earlier in the MYTP.

5.5.6 Accordingly, after taking into account the revised submission for cost of debt submitted by GHIAL, the weighted average cost of debt work out as 8.82%.

5.5.7 The Effective Cost of Debt has been arrived at based on the weighted average of Cost of Debt based on the average principal outstanding for the years in the Third Control Period.

Gearing Ratio

5.5.8 GHIAL has considered a gearing ratio of 48:52, i.e., 48% debt and 52% equity, for computation of the Weighted Average Cost of Capital for the Third Control Period.

Calculation of WACC:

5.5.9 GHIAL considered the same methodology for calculation of WACC as adopted by the Authority in the Tariff Order for the Third Control Period and the WACC as calculated by GHIAL stands at 12.12% with normative debt and equity at 48% and 52% respectively.

Table 59: WACC decided by the Authority as per the Tariff Order for the Third Control Period Particulars Cost of Funds Gearing Effective Rate Equity 15.17% 52.00% 7.89% Debt 8.99% 48.00% 4.31% WACC / FRoR 12.20% Authority’s Examination regarding True up of WACC for the third Control Period

5.5.17 The Authority examined the submission made by GHIAL and notes that GHIAL has adopted Cost of Equity at 15.17% which is consistent with the decision taken by the Authority during the tariff determination for the Third Control Period based on the Independent Study conducted by IIM Bangalore. Hence, the Authority proposes to consider the Cost of Equity at 15.17% towards True Up for the Third Control Period.

5.5.18 The Authority notes GHIAL's submission of Cost of Debt at 8.82% towards True Up for the Third Control Period. The Authority notes that the calculation is based on the weighted average of the year-wise effective cost of debt computed on the average principal outstanding during the Third Control Period. Accordingly, the year-wise effective cost of debt as submitted by GHIAL is 9.18% (FY22), 9.00% (FY23), 8.55% (FY24),

8.54% (FY25) and 8.88% (FY26), resulting in a weighted average cost of debt of 8.82% for the Third Control Period. It is to be noted that the Cost of Debt of 8.82% as submitted by GHIAL is lower than the effective cost of the individual debt instruments, primarily on account of the Interest Free Loan from the State Government and the refinancing of higher-cost USD borrowings through lower-cost domestic INR NCDs. The Authority therefore finds the submission of GHIAL towards the Weighted Cost of Debt of

8.82% reasonable. The Authority consistent with the decision taken at the time of tariff determination for the Third Control Period proposes to consider the normative debt-equity proportion of 48:52 as decided in

Order No. 12/2021-22 for the Third Control Period.

5.5.19 The Authority notes that GHIAL has considered a gearing ratio of 48:52, i.e., 48% debt and 52% equity, for computation of the Weighted Average Cost of Capital for the Third Control Period and the same has been considered for the purpose of computation of WACC.

WACC

5.5.20 Based on the above, the resulting WACC proposed to be considered by the Authority towards True Up for the Third Control Period works out to 12.12% , in line with GHIAL’s submission, as shown in the table

Consultation Paper No: 02/2026-27 Page 80 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Reason for increase in various heads of expenditure as per GHIAL Rates & Taxes

5.6.4 GHIAL has submitted that there has been a considerable increase in expenses in FY2023 which is on account of payment made to HMWSSB towards increasing the water supply capacity (Rs. 4.95 Cr) and on account of increase in property tax (Rs. 1.9 Cr) owing to phase wise commissioning of 34 MPPA.

Bank Charges & Forex Fluctuations

5.6.5 GHIAL has submitted that the substantial variation in Bank Charges during the Third Control Period is primarily on account of interest on working capital facilities availed by GHIAL and delayed payment interest on Concession Fee payable to the Ministry of Civil Aviation (MoCA). In FY22 alone, Bank Charges include an amount of Rs. 17.75 Crore towards interest on working capital facility and Rs. 5.62 Crore towards delayed payment interest on Concession Fee.

5.6.6. GHIAL has further submitted that a substantial rise in forex loss in FY23, which is attributed to refinancing FCB 2024 and FCB 2026 by raising domestic NCDs to mitigate forex exposure. The amount of Rs.90.77 Cr is on account of breaking of hedge contract.

Repair & Maintenance

5.6.6 GHIAL has submitted that, the Authority had considered 0.5% of the new additions as repairs & maintenance expenses instead of GHIAL proposal of 1.5%. This has resulted in the gap (of 112.48 Crores) between the Authority’s projection vs actual incurrence by GHIAL for the 3rd Control Period.

Stores & Spares (Consumables)

5.6.7. GHIAL has submitted that Stores and Spares are primarily utilised for the maintenance of the terminal building and airside infrastructure at RGIA and with the existing terminal building having been in continuous operation for a period in excess of fifteen (15) years, the consumption of Stores and Spares has progressively increased, on account of the higher maintenance intensity associated with ageing infrastructure.

5.6.8. GHIAL has further submitted that the Authority, in determining the Aeronautical Consumables expenses for the Third Control Period, had considered a COVID-19-impacted financial year as the base, with the corresponding expense being ₹ 3.84 Crore. GHIAL has contended that, in the preceding normal financial year, the actual expenses incurred amounted to ₹ 7.16 Crore, and the said normal-year figure ought to have been considered as the appropriate base for projecting the Aeronautical Consumables expenses for the Third Control Period.

Insurance Cost

5.6.9. GHIAL has submitted that the increase in insurance cost is primarily due to an increase in the sum insured, arising from incremental capitalisation of assets and an expanded coverage base.

Rent

5.6.10. GHIAL has submitted that the increase in Rent expenses during the Third Control Period is attributable to

the following factors:

(i) Hiring of additional office space to meet business requirements with effect from FY 2023–24, entailing an annual rental cost of approximately Rs. 3.70 Crore;

Consultation Paper No: 02/2026-27 Page 81 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

(ii) Hiring of additional office space with effect from FY 2024–25, entailing an annual rental cost of approximately Rs. 2.60 Crore; and

(iii) Year-on-year escalation provided for under the other rental contracts subsisting during the Third Control Period.

Manpower Hire Charges

5.6.11. GHIAL has submitted that Manpower Hire Charges represent the cost incurred towards contractors engaged for the deployment of outsourced personnel at Rajiv Gandhi International Airport, Hyderabad ("RGIA") and the contracts are structured to incorporate an annual escalation typically ranging between 5% and 8% per annum, in line with periodic revisions in the applicable statutory minimum wages. GHIAL has, accordingly, considered a realistic escalation rate of 7% per annum for the purposes of projecting Manpower Hire Charges. GHIAL has further submitted that the Authority, in its determination for the Third Control Period, did not adequately account for the said macroeconomic escalation factor, which has resulted in the approval of expense levels that are lower than the actual expenditure incurred by GHIAL during the said period.

5.6.12. GHIAL has additionally submitted that, on account of the expansion in airport operations, including the increase in terminal capacity and passenger throughput during the Third Control Period, the operating cost

incurred under this head has correspondingly increased:

5.6.13. GHIAL has further submitted that certain incremental costs, which were not envisaged at the time of the determination for the Third Control Period, have been incurred during the said period, the particulars of

which are as follows: i. Implementation of Digi Yatra Services: Pursuant to the "Digi Yatra" initiative introduced by the Ministry of Civil Aviation, Government of India ("MoCA"), GHIAL has incurred additional expenditure towards the implementation and ongoing operation of Digi Yatra services at RGIA.

The said expenditure has resulted in incremental Manpower Hire Charges of approximately ₹ 12 Crore per annum, with effect from FY 2024–25; and ii. Deployment of GADL Personnel for General Capex Monitoring: GHIAL has engaged GMR Airports Developers Limited ("GADL") to deploy a team of sixteen (16) personnel for the purposes of monitoring and execution support in respect of the new General Capital Expenditure ("Capex") initiatives and projects undertaken at RGIA. The said engagement has resulted in incremental annual expenditure of ~5.40 Crore.

5.6.14. GHIAL has further submitted that the Authority, in determining the Manpower Hire Charges for the Third Control Period, had considered a COVID-19-impacted financial year as the base year, with the corresponding expense being ₹ 37.53 Crore. GHIAL has contended that, in the preceding normal (pre- COVID-19) financial year, the actual expenses incurred under this head amounted to ₹ 43.75 Crore, and the said normal-year figure ought to have been considered as the more appropriate and representative base for projecting Manpower Hire Charges for the Third Control Period.

CGF expense

5.6.15. GHIAL has submitted that the Authority, in determining the Fuel Farm expenses for the Third Control Period, had projected the said expense solely on the basis of inflation, without factoring in certain critical

Consultation Paper No: 02/2026-27 Page 82 of 308TRUE UP FOR THE THIRD CONTROL PERIOD growth drivers, including, inter alia, Air Traffic Movements ("ATMs") and fuel upliftment at Rajiv Gandhi International Airport, Hyderabad ("RGIA");

5.6.16. GHIAL submitted that the increase in actual Fuel Farm expenses observed during FY 2022–23 is principally attributable to a rise in fuel upliftment at RGIA of approximately 48% during the said financial year;

5.6.17. GHIAL has further submitted that increased maintenance costs, arising from the ageing of vehicles and equipment deployed for Fuel Farm operations, have additionally contributed to the higher operating expenses incurred under this head, particularly during FY 2025–26; and

5.6.18. GHIAL has additionally submitted that the Authority, in determining the Fuel Farm expenses for the Third Control Period, had considered a COVID-19-impacted financial year as the base year, with the corresponding expense being ₹ 12.62 Crore. GHIAL has contended that, in the preceding normal financial year, the actual expenses incurred under this head amounted to ₹ 18.29 Crore, and the said normal-year figure ought to have been considered as the more appropriate and representative base for projecting Fuel Farm expenses for the Third Control Period.

General Admin Expense

5.6.19. GHIAL has submitted that the base year considered for the projection of General Administration Expenses for the Third Control Period corresponded to a COVID-19-impacted financial year, during which several routine general administrative activities, travel and conveyance, business meetings and conferences, training and development, printing and stationery, and ancillary office expenses, stood temporarily moderated on account of the disruption in airport operations. With the post-pandemic normalisation of operations at Rajiv Gandhi International Airport, Hyderabad ("RGIA"), the said expenses have progressively reverted to, and progressed in line with, the steady-state operating profile of the Airport.

5.6.20. GHIAL has further submitted that the Third Control Period has witnessed a substantial expansion in the operational scale of RGIA on account of the increase in terminal capacity, passenger throughput, ATM volumes, manpower deployment, and operational complexity at the Airport. The said expansion has objectively necessitated a commensurate scaling-up of general administrative activities required to support the larger operational footprint and has correspondingly resulted in a structural increase in the said expense head.

Aeronautical allocation of Operating Expenses as submitted by GHIAL

5.6.21. GHIAL has submitted that the allocation of total O&M expenses between aeronautical and non-aeronautical

activities has been carried out based on the following methodology: i. All the expenditure attributable directly to Aeronautical services or Non-aeronautical services were allocated accordingly as Aero and Non-Aero costs. The classification of the expenditure is done based on the nature of the cost center and respective expenditure incurred in the cost center.

ii. For the common costs outside the Terminal, which cannot be directly allocated, the expenses are apportioned based on an appropriate driver such as the Gross Fixed Asset Ratio or the Aero-Non Aero Expense Ratio of Aeronautical and Non-Aeronautical for the relevant year.

5.6.29. The Authority’s analysis of aeronautical operating expenses for True up for the Third Control Period is based on the revised submissions made by GHIAL vide e-mail dated 02.05.2026.

5.6.30. The Authority, through the Independent Consultant, has examined the True-up of O&M Expenses for the Third Control Period based on detailed review of the submissions and records furnished by GHIAL. In this regard, the following documents / information have been considered by the Authority:

i. Ledgers and other internal records maintained by GHIAL in respect of O&M Expenses for the Third Control Period; ii. Audited Financial Statements of GHIAL for FY22-FY25 and unaudited Financial Statement for FY26;

iii. Explanations and clarifications furnished by GHIAL regarding the reasons for variation in various sub- items of Operating Expenses during the Third Control Period; and iv. Chartered Accountant certificates submitted by GHIAL, including those relating to the allocation of Operating Expenses between Aeronautical and Non-Aeronautical activities along with the basis / justifications thereof.

5.6.31. Based on the aforesaid examination, the Authority notes that GHIAL has submitted Aeronautical O&M Expenses of Rs. 3,277.23 Crores for True up of Third Control Period as against Rs. 2,750.57 Crores approved by the Authority in the Tariff Order for the Third Control Period with the resultant variation of

19.14%.

5.6.32. The Authority based on its examination and considerations has reevaluated the GFA (treating CGF assets as aeronautical) and Aero-Non Aero Expense Ratio (Aero Opex: Non-Aero Opex) to apportion the common

expenses as per the table below:

5.6.36. The Authority further notes that the major variation is primarily under certain expense heads such as Repair & Maintenance, Rates & Taxes, Manpower Hire Charges, Bank Charges, Consumables, Rent and General Admin Expense. Accordingly, after undertaking prudence check and examining the documentary evidence, supporting submissions and Chartered Accountant certificates furnished by GHIAL, the Authority has analyzed the reasons for such variation under each expense head including other heads, as discussed in the ensuing paragraphs.

Manpower Cost

5.6.37. The aeronautical Manpower expenses approved by the Authority for the Third Control Period and

aeronautical Manpower expenses as submitted by GHIAL for True up is provided in the table below:

5.6.38. The Authority notes that the Aeronautical Manpower expenses submitted by GHIAL for the Third Control Period in the MYTP for the Fourth Control Period (Rs. 632.80 Cr) is ~12.7% lower than the Aeronautical manpower expenses approved by the Authority in the Third Control Period (Rs. 725.45 Cr).

5.6.39. The Authority analysed the details pertaining to count of manpower deployed at the airport and the expense per employee as submitted by GHIAL. The same is provided below:

5.6.40. The Authority notes that the decrease in Manpower expenses witnessed during FY 2025–26 is attributable to certain manpower realignments undertaken across the GMR Group during the said financial year. GHIAL has, in this regard, furnished the following particulars in respect of the said manpower movements:

i. Transfer of Specialised Staff to Bhogapuram Airport: Certain specialised staff have been transferred to Bhogapuram International Airport (operated by an associate entity within the GMR Group), in view of the impending Commercial Operations Date ("COD") of the said airport;

ii. Transfer of Commercial Operations Team: Certain personnel from the commercial operations function have been transferred to GMR Airports Limited to meet the business requirements of the said entity;

iii. Transfer of Personnel to Shared Services: Certain personnel have been transferred to GMR Airports Limited to operate under a shared services arrangement, whereby the said personnel continue to discharge functions in support of GHIAL's operations on a shared basis;

iv. Continued Discharge of GHIAL Functions: GHIAL has further submitted that the aforesaid transfers have been undertaken to address resource requirements at the Group level, and that the transferred personnel continue to extend support to GHIAL on an additional-responsibility basis, to the extent feasible; and v. Transfer of CSR Personnel: Certain personnel engaged in Corporate Social Responsibility ("CSR") initiatives have been transferred to the GMR Varalakshmi Foundation, being the dedicated entity for undertaking CSR activities at the Group level.

5.6.41. The Authority also notes that the reduction in Manpower expenses during the Third Control Period is on account of delay in operationalization of Terminal Expansion plan, the said expansion having been commissioned in FY 2023-24 as against the originally envisaged timeline of FY 2020-21, and subsequent delay in hiring of manpower related to Terminal Expansion.

5.6.42. The Authority, in line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, proposes to allocate the Manpower expenses incurred by GHIAL during the Third Control Period on the basis of the GFA ratio.

5.6.43. Based on the above, the Aeronautical Manpower expenses proposed to be considered by the Authority for

True up for the Third Control Period is provided in the table below:

Table 74: Manpower expenses proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Manpower expenses 96.96 101.50 135.97 159.25 146.03 639.72

5.6.44. The Authority notes that GHIAL has submitted total Manpower expense of Rs. 737.76 Crores (ref. Table

70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non- aeronautical, the aeronautical Manpower expense as per GHIAL is Rs. 632.80 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Manpower expense attributable to aeronautical services has been computed at Rs. 639.72 Crores (ref. Table 74). In this context, it is pertinent to note that

Consultation Paper No: 02/2026-27 Page 91 of 308TRUE UP FOR THE THIRD CONTROL PERIOD the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement

(ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

Rates & Taxes

5.6.45. Rates & Taxes expense primarily comprises the property tax, and the yearly payment towards PUC.

5.6.46. The Aeronautical Rates and Taxes approved by the Authority for the Third Control Period and submitted

by GHIAL for True up are provided in the table below:

5.6.47. The Authority notes that the Aeronautical Rates & Taxes submitted by GHIAL for the Third Control Period in the MYTP for the Fourth Control Period (Rs. 35.78 Cr) is marginally higher than the Aeronautical Rates & Taxes approved by the Authority in the Tariff Order for the Third Control Period and the same has also been verified though relevant documents including CA certificates.

5.6.48. The Authority also notes the considerable increase in expenses in FY 2023 which was on account of payment made to HMWSSB towards increasing the water supply capacity (Rs. 4.95 Cr) and on account of increase in property tax (Rs. 1.9 Cr) owing to phase wise commissioning of 34 MPPA.

5.6.49. The Authority, in line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, proposes to allocate the Rates & Taxes expenses incurred by GHIAL during the Third Control Period on the basis of the GFA ratio.

5.6.50. The Authority notes that GHIAL has submitted total Rates & Taxes of Rs. 39.73 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Rates & Taxes as per GHIAL is Rs. 35.78 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the

Consultation Paper No: 02/2026-27 Page 92 of 308TRUE UP FOR THE THIRD CONTROL PERIOD allocation ratio considered by GHIAL, the Rates & Taxes attributable to aeronautical services has been computed at Rs. 36.20 Crores (ref. Table 76). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

Bank Charges and Forex Fluctuations

5.6.51. The Aeronautical Bank charges, Forex Fluctuations approved by the Authority for the Third Control Period

and submitted by GHIAL for True up are provided in the table below:

5.6.52. The Authority has examined the historical trajectory of Bank Charges incurred by GHIAL across the past Control Periods, and observes that the year-on-year movement in the said expense head has been highly variable and erratic, with the year-on-year growth rates oscillating across a wide range. The Authority is of the considered view that no discernible or consistent trend could be established on the basis of the said historical growth rates, the said variability being symptomatic of the event-driven and non-recurring nature of the constituents underlying this expense head.

5.6.53. The Authority further observes that the substantial variation in Bank Charges during the Third Control Period is primarily attributable to the following two non-routine constituents:

(a) Interest on Working Capital Facilities availed by GHIAL during the said period; and

(b) Delayed Payment Interest on Concession Fee payable to the Ministry of Civil Aviation ("MoCA").

5.6.54. The Authority has examined the variance between the total Bank Charges approved in the Tariff Order for the Third Control Period and the actual Bank Charges incurred by GHIAL during FY 2021-22, the said variance of Rs. 19.10 Crores is primarily attributable to two distinct cost components, both of which are directly traceable to the financial measures undertaken by GHIAL in response to the COVID-19 pandemic:

(i) Interest on Working Capital Facility – ₹17.75 Crores: The Authority observes that, in view of the severe and unprecedented impact of the COVID-19 pandemic on the revenue streams of Rajiv Gandhi International Airport, Hyderabad ("RGIA"), GHIAL availed working capital facilities during FY 2021- 22 to preserve adequate cash balances and to safeguard against further operational and financial uncertainties arising from the pandemic. The said facility entailed an interest cost of ₹17.75 Crores during the said financial year.

(ii) Interest on Deferred Concession Fee – ₹5.63 Crores: The Authority observes that, pursuant to the dispensation granted by the Ministry of Civil Aviation, Government of India ("MoCA"), GHIAL was permitted to defer the payment of the Concession Fee payable to the Ministry of Civil Aviation during the pandemic period, so as to conserve cash flows during the period of disruption. The said deferment carried a corresponding interest cost of ₹5.63 Crores, in terms of the MoCA communication on record.

5.6.55. The Authority observes that the Ministry of Civil Aviation, Government of India ("MoCA"), vide its communication dated 19.10.2022, has, in the matter of the deferment of Concession Fee payable by GHIAL during the COVID-19 pandemic period, recorded the following:

(i) Deferment of Concession Fee: Pursuant to the request of GHIAL, MoCA deferred the payment of the Concession Fee due on 30 June 2020 by a period of six (6) months, viz., until 31 December 2020, with a view to alleviating the cash flow stress occasioned by the pandemic-induced disruption in airport operations;

(ii) No Waiver of Interest: The said deferment, however, did not extend the original due date of payment, and no corresponding waiver of interest in respect of the deferred period was approved by MoCA; and

(iii) Liability for Interest at SBI PLR + 2%: GHIAL was, accordingly, required to discharge the Concession Fee payments for the deferred period together with interest computed at the State Bank of India Prime Lending Rate plus two per cent (SBI PLR + 2%), in terms of Clause 18.14 of the Concession Agreement subsisting between GHIAL and the Ministry of Civil Aviation.

5.6.56. The Authority observes that the interest cost incurred by GHIAL on the deferred Concession Fee payments during the Third Control Period is, accordingly, in the nature of a contractually binding cost, having been levied in accordance with the express terms of the Concession Agreement and pursuant to the directions issued by MoCA.

The said cost is, by its very nature, non-discretionary and exogenous to GHIAL, and is directly attributable to the exceptional pandemic-related circumstances that necessitated the deferment of Concession Fee payments to preserve operational liquidity during the said period.

5.6.57. The break-up of Interest on Working Capital Facility and Interest on Deferred Concession Fee incurred by GHIAL

is as per the table below:

Table 78: Break up of Interest on Working Capital Facility and Interest on Deferred Concession Fee as submitted by GHIAL Particulars FY 22 FY 23 FY 24 FY 25 FY 26 Interest on delayed payment of Concession Fee 5.63 10.18 - - - Working Capital Interest 17.75 17.32 2.48 - - Total 23.38 27.50 2.48

5.6.58. The Authority observes that the said variance is, in its entirety, attributable to exceptional pandemic-related circumstances and to the necessary financial measures undertaken by GHIAL to ensure (i) the maintenance of adequate liquidity, and (ii) the uninterrupted continuation of airport operations at RGIA during the pandemic. The said costs are, by their very nature, non-recurring, event-driven, and exogenous to the steady-state operating

Consultation Paper No: 02/2026-27 Page 94 of 308TRUE UP FOR THE THIRD CONTROL PERIOD profile of the Airport, and are not reflective of the routine Bank Charges ordinarily incurred in the conduct of airport operations.

5.6.59. Based on the foregoing, Aeronautical Bank charges proposed to be considered by the Authority for the Third

Control period is provided in the table below:

Table 79:Aeronautical Bank Charges proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Bank Charges 27.84 38.84 13.51 23.90 11.87 115.95

5.6.60. The Authority notes that GHIAL has submitted total Bank Charges of Rs. 130.43 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non- aeronautical, the aeronautical Bank Charges as per GHIAL is Rs. 115.22 Crores (ref. Table 77). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Bank Charges attributable to aeronautical services has been computed at Rs. 115.95 Crores (ref. Table 79). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement

(ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

Forex Fluctuations

5.6.61. The Authority notes a substantial rise in forex loss in FY23, which is attributed to refinancing FCB 2024 and FCB 2026 by raising domestic NCDs to mitigate forex exposure. The amount of Rs.90.77 Cr is on account of breaking of hedge contract.

5.6.62. The Authority, in this regard, sought a Cost-Benefit Analysis from GHIAL in respect of the Hedge Break Cost.

Upon examination of the "Note on Hedge Break Cost" submitted by GHIAL, the Authority observes that the FCBs which were due to mature in April 2024 and February 2026, were refinanced in Dec 2022 i.e. just 16 months and 26 months prior to their maturity date. Also, ECD 2024 was refinanced in March 2023.

Further, the Authority observes that the cost benefit analysis as submitted by GHIAL considers a period of 5 years. Considering only the remaining period to maturity for these FCDs and ECD, the computation resulted in net loss on account of breaking of Hedge for the existing FCDs and ECD.

5.6.63. Therefore, the Authority observes that the decision to break the hedge contract resulted in net loss to the airport users. In the absence of such cost-benefit substantiation, the Authority is of the considered view that the Hedge Break Cost of ₹90.77 Crore is not to be allowed as pass through to airport users, and accordingly proposes to disallow the same. Further the other marginal costs incurred on account of foreign exchange fluctuations related to travel and procurement etc during the Third Control Period amounting to Rs 1.78 Crores is also disallowed.

5.6.64. Based on the foregoing, the Authority proposes to consider the Aeronautical Bank Charges and Forex Fluctuations for the True-up of the Third Control Period at Rs. 115.95 Crores, as against Rs. 198.16 Crores submitted by GHIAL, as per the table below:

Consultation Paper No: 02/2026-27 Page 95 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Table 80: Aeronautical Bank Charges and Forex Fluctuations proposed by the Authority for True up of the Third Control Period (Rs.

5.6.65. The security expenses are primarily driven by the security-related requirements, particularly towards engagement of outsourced security personnel.

5.6.66. The Aeronautical Security expenses approved by the Authority for the Third Control Period and submitted by

GHIAL for True up are provided in the table below:

Table 81: Comparison of Security Expense as submitted by GHIAL for True up and as approved by the Authority in the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Security Expenses approved by the

5.6.67. The Authority notes that the Aeronautical security expenses submitted by GHIAL is ~58% lower than the expenses approved in the Tariff Order for the Third Control Period. The same have been verified with relevant documents, including CA certificates, and are found to be reasonable.

5.6.68. The Authority notes that these security personnel are deployed in terminal building as well as landside access, kerbside, common circulation areas, administrative offices, etc.

5.6.69. The Authority notes that the reduction in security expenses during the Third Control Period is on account of delay in operationalization of Terminal Expansion plan and subsequent delay in hiring of security personnel related to Terminal Expansion.

5.6.70. The Authority further notes that there has been a minor reduction in security expenses amounting to ₹2.67 crore in FY26, attributable to the ongoing development of the airport. As new concessionaires are onboarded on the landside, the associated security expenses are being borne by the respective concessionaires.

5.6.71. In line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, the Authority proposes to allocate the Security expenses incurred by GHIAL during the Third Control Period on the basis of the GFA ratio.

5.6.72. The Aeronautical Security Expense proposed to be considered by the Authority for the Third Control Period

are provided below:

Consultation Paper No: 02/2026-27 Page 96 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Table 82: Aeronautical Security Expense proposed by the Authority for True up of the Third Control period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Security Expense 12.97 18.61 19.12 18.37 16.21 85.29

5.6.73. The Authority notes that GHIAL has submitted total Security Expense of Rs. 100.53 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non- aeronautical, the aeronautical Security Expense as per GHIAL is Rs. 84.08 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Security Expense attributable to aeronautical services has been computed at Rs. 85.29 Crores (ref. Table 82). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement

(ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

Repairs and Maintenance Expenses

5.6.74. Repairs and Maintenance expenses include civil, electrical and mechanical maintenance works relating to the airport, including terminal, runways, taxiways, parking bays, aprons, aerobridges, power substations, IT systems, plant and machinery

5.6.75. The Aeronautical R&M expenses approved by the Authority for the Third Control Period and submitted by

GHIAL for True up are provided in the table below:

Table 83: Comparison of R&M Expense as submitted by GHIAL for True up and as approved by the Authority in the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical R&M Expenses approved by the

5.6.76. The Authority notes that the R&M expenses submitted by GHIAL for the Third Control Period in the MYTP for the Fourth Control Period (Rs. 469.18 Cr) is ~31.5% higher than the Aeronautical R&M expenses approved by the Authority in the Third Control Period (Rs. 356.70 Cr) and the expenses have been verified with relevant documents, including CA certificates.

5.6.77. The Authority observes that, while the R&M expenses for the Third Control Period were projected on a conservative basis with reference to the new asset additions, the actual expenditure incurred by GHIAL during the said period falls within a range of approximately 0.5% to 1% of the asset additions. The Authority

Consultation Paper No: 02/2026-27 Page 97 of 308TRUE UP FOR THE THIRD CONTROL PERIOD is of the considered view that the said actual range is linked to the operational and lifecycle-driven maintenance requirements of the asset base.

5.6.78. The Authority has further undertaken benchmarking analysis based on actual data for the period FY23 to FY25, with reference to Repair and Maintenance (R&M) cost per passenger and R&M cost per terminal area across comparable airports. Based on such analysis, Authority notes that GHIAL’s average R&M cost for the said three-year period works out to approximately Rs. 45 per passenger and Rs. 3,373 per square meter, which is observed to be lower than the corresponding levels of other comparable airports such as BIAL, MIAL and AIAL.

5.6.79. The Authority observes that the R&M expense as a percentage of Gross Block (Aero) has trended downward from 2.52% to 1.80% over the period, a reduction of approximately 72 basis points, the said decline being largely on account of the substantial expansion of the Gross Block consequent to the capitalisation of the Terminal Expansion and associated assets.

5.6.80. The Authority is, therefore, of the considered view that the actual incurrence reflects the true maintenance requirement of the asset base, particularly in light of the phase-wise commissioning of the 34 MPPA terminal expansion during the Third Control Period.

5.6.81. Having regard to the audited actuals furnished by GHIAL, supported by Chartered Accountant certification, and the absence of any indication of imprudence on the part of the Airport Operator, the Authority proposes to consider the actual R&M expenditure incurred during the Third Control Period for the purpose of the True-Up.

5.6.82. Based on the above, Aeronautical Repair & Maintenance expense proposed to be considered by the

Authority for the Third Control Period is shown in the table below:

Table 84: Aeronautical Repair & Maintenance expenses proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical R&M Expenses 56.67 81.34 105.58 113.96 113.37 470.92

5.6.83. The Authority notes that GHIAL has submitted total Repair & Maintenance expenses of Rs. 491.00 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Repair & Maintenance expenses as per GHIAL is Rs. 469.18 Crores (ref.

Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Repair & Maintenance expenses attributable to aeronautical services has been computed at Rs. 470.92 Crores (ref. Table 84). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

Consultation Paper No: 02/2026-27 Page 98 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Consumables (Stores & Spares)

5.6.84. The Aeronautical Consumables expenses approved by the Authority for the Third Control Period and

submitted by GHIAL for True up are provided in the table below:

Table 85: Comparison of Consumables expense as submitted by GHIAL for True up and as approved by the Authority in the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Consumables expenses approved by the

5.6.85. The Authority notes that the Aeronautical Consumables expenses submitted by GHIAL for the Third Control Period in the MYTP for the Fourth Control Period is ~121% higher than the Aeronautical Consumables expenses approved by the Authority in the Third Control Period. The same has also been verified through relevant documents including CA certificates.

5.6.86. The Authority observes that Stores and Spares Consumption, which forms part of the Aeronautical Consumables expenses, is incurred on the basis of planned maintenance activities undertaken at Rajiv Gandhi International Airport, Hyderabad ("RGIA"), and represents the cost of spares consumed in the course of the said maintenance activities. The said expense head is, by its very nature, directly correlated with the age, scale, and operational intensity of the underlying infrastructure being maintained.

5.6.87. Having regard to the materiality of the variance between the projected and actual figures, the Authority, in the course of its detailed examination, sought further clarification from GHIAL in respect of the underlying drivers contributing to the said variance.

5.6.88. The Authority, upon detailed examination of the submissions made by GHIAL and the supporting documentation furnished in respect thereof, identifies the following structural and operational factors as the drivers underlying the higher Aeronautical Consumables expenses incurred during the Third Control

Period:

(i) Nature and Purpose of Consumption: The Authority observes that the Stores and Spares are primarily deployed for the maintenance of the terminal building and airside infrastructure at RGIA. The consumption thereof is, by its very nature, non-discretionary and is dictated by the operational and safety requirements of maintaining critical airport infrastructure to the requisite serviceability and safety standards.

(ii) Lifecycle-Driven Increase in Maintenance Intensity: The Authority observes that the existing terminal building at RGIA has been in continuous operation for a period in excess of fifteen (15) years. As is consistent with the typical lifecycle cost profile of infrastructure assets, the maintenance intensity — and the corresponding consumption of Stores and Spares — progressively increases with the aging of the underlying assets. The said increase is bona fide, operationally inevitable, and reflective of the structural maintenance requirements of an aging terminal and airside infrastructure.

Consultation Paper No: 02/2026-27 Page 99 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

(iii) Post-Pandemic Normalisation of Maintenance Activities: The Authority observes that the base year figure of ₹3.84 Crores considered for projecting the Aeronautical Consumables expenses for the Third Control Period corresponded to a COVID-19-impacted financial year, during which the maintenance activities at the Airport stood temporarily moderated on account of the disruption in operations and the consequential deferral of certain non-critical maintenance interventions. The Authority observes that, in the immediately preceding pre-pandemic financial year, the actual expenses incurred under this head amounted to ₹7.16 Crores, the said figure being more reflective of the steady-state pre-pandemic maintenance profile of the Airport. Notably, the Authority observes that the actual Stores and Spares cost incurred during the Third Control Period is broadly comparable to the said pre-pandemic baseline, when adjusted for inflation and the lifecycle-driven uplift, indicating that the actual incurrence is representative of the true maintenance requirement of the Airport in normal operating conditions.

5.6.89. The Authority is, accordingly, of the considered view that the cumulative effect of the foregoing factors, viz., (i) the non-discretionary nature of the consumption; (ii) the lifecycle-driven increase in maintenance intensity associated with the aging terminal building; and (iii) the post-pandemic normalisation of maintenance activities, is reflective of the true maintenance requirement of the terminal building and airside infrastructure at RGIA, particularly having regard to the fact that the existing terminal building has been in continuous operation for a period in excess of fifteen (15) years.

5.6.90. The said expenses, having been duly substantiated by Chartered Accountant certificates and supporting documentation, are accordingly found to be prudent and justifiable for the purposes of the true-up exercise.

5.6.91. The Authority in line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, proposes to allocate the common expense pertaining to Stores & Spares incurred by GHIAL during the Third Control Period on the basis of the GFA ratio.

5.6.92. Based on the foregoing, Aeronautical Consumables expenses proposed to be considered by the Authority

for the Third Control Period is shown in the table below:

Table 86: Aeronautical Consumables expenses proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Consumables expenses 4.13 11.66 15.67 14.03 13.13 58.63

5.6.93. The Authority notes that GHIAL has submitted total Consumables expenses of Rs. 61.43 Crores (ref. Table

70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non- aeronautical, the aeronautical Consumables expenses as per GHIAL is Rs. 58.54 Crores (ref. Table 71).

The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Consumables expenses attributable to aeronautical services has been computed at Rs. 58.63 Crores (ref. Table 86). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical

Consultation Paper No: 02/2026-27 Page 100 of 308TRUE UP FOR THE THIRD CONTROL PERIOD revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

Insurance Cost

5.6.94. The Authority notes that the key insurance policies for the airport are as follows: • Large Risk Policy (Property Damage & Business Interruption (BI)) • AOL/3rd Party Liability Policy • Terrorism Policy • Cyber Security Policy

5.6.95. The Aeronautical Insurance expenses approved by the Authority for the Third Control Period and submitted

by GHIAL for True up are provided in the table below:

The Authority notes that the Aeronautical Insurance Expenses submitted by GHIAL for the Third Control Period in the MYTP for the Fourth Control Period is 23.92% higher than the Aeronautical Insurance Expenses approved by the Authority in the Third Control Period and the same has also been verified through relevant documents including CA certificates.

5.6.97. The Authority notes that the increase in insurance cost is primarily due to an increase in the sum insured,

arising from incremental capitalisation of assets and an expanded coverage base as shown in table below:

In line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, the Authority proposes to allocate the Insurance expenses incurred by GHIAL during the Third Control Period on the basis of the GFA ratio.

5.6.99. Based on the above, Aeronautical Insurance expense proposed to be considered by the Authority for the Third

Control Period is shown in the table below:

Table 89: Aeronautical Insurance expenses proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Insurance Expenses 5.08 5.40 6.41 6.80 8.14 31.83

5.6.100. The Authority notes that GHIAL has submitted total Insurance expenses of Rs. 35.57 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Insurance expenses as per GHIAL is Rs. 31.34 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Insurance expenses attributable to aeronautical services has been computed at Rs. 31.83 Crores (ref.

Table 89). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

Land Lease Rent

5.6.101. Rent expenses primarily comprise the lease rent paid to the Government of Telangana, along with other rental expenses.

5.6.102. The Aeronautical Rent expenses approved by the Authority for the Third Control Period and submitted by GHIAL

for True up are provided in the table below:

5.6.103. The Authority notes that the Aeronautical Rent expenses submitted by GHIAL for the Third Control Period in the MYTP for the Fourth Control Period, amounting to Rs. 58.49 Crore are approximately 3.5 times higher than the Aeronautical Rent expenses approved by the Authority in the Tariff Order for the Third Control Period. The Authority further notes that the said expenses have been verified with reference to relevant supporting documents, including Chartered Accountant certificates furnished by GHIAL.

5.6.104. The Authority notes that the increase in Rent expenses during the Third Control Period is attributable to the

following factors:

(i) Hiring of additional office space in the new office building (NOB), with effect from FY 2023-24, to meet the expanding operational requirements of the Airport, entailing an annual rental cost of approximately ₹3.70 Crores;

(ii) Hiring of further additional office space in the new office building (NOB), with effect from FY 2024- 25, in response to the continued growth in operational scale and manpower deployment, entailing an annual rental cost of approximately ₹2.60 Crores; and

(iii) Year-on-year contractual escalations provided for under the other rental contracts subsisting during the Third Control Period.

5.6.105. The Authority notes that an additional office space of 68,928 sq.ft area was leased starting from 12.04.2023 and 33,439 sq.ft starting from 03.01.2024.

5.6.106. The Authority observes that the office spaces in respect of which the aforesaid Rent expenses have been incurred have been taken on lease by GHIAL exclusively for the purposes of carrying out the operations of Rajiv Gandhi International Airport, Hyderabad ("RGIA").

5.6.107. The Authority further observes that the structural growth in the operational footprint of RGIA during the Third Control Period is on account of the substantial expansion in passenger throughput, ATM volumes, terminal area, and the consequential augmentation in operational, security, and administrative manpower which has necessitated the commensurate augmentation of office and operational space at the Airport. The leasing of additional office space is linked to the evolving operational requirements emerging at the airport.

5.6.108. Having regard to (i) the verification of the said expenses with reference to supporting documentation including Chartered Accountant certificates; (ii) the operational connection of the leased office spaces with the conduct of airport operations at RGIA; and (iii) the structural drivers underlying the augmentation in space requirements, the Authority is of the considered view that the Aeronautical Rent expenses incurred by GHIAL during the Third Control Period are justifiable.

Consultation Paper No: 02/2026-27 Page 103 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.6.109. The Authority further observes that the rental expenses incurred by GHIAL pertain partly to facilities used in common for both Aeronautical and Non-Aeronautical operations. In line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, the Authority proposes to allocate the Rent expenses incurred on common facilities by GHIAL during the Third Control Period on the basis of the GFA ratio.

5.6.110. Based on the foregoing, the Aeronautical Rent Expenses proposed to be considered by the Authority for the Third

Control Period are provided in the table below:

Table 91: Aeronautical Rent expenses proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Rent Expenses 6.76 10.99 10.49 15.04 15.74 59.01

5.6.111. The Authority notes that GHIAL has submitted total Rent expenses of Rs. 69.69 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Rent expenses as per GHIAL is Rs. 58.49 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Rent expenses attributable to aeronautical services has been computed at Rs. 59.01 Crores (ref. Table

91). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

Manpower Hire/Manpower Outsourcing Charges

5.6.112. The Manpower Hire expense pertains to manpower deputation and outsourced manpower services deployed for operational and project-related requirements. The key components include manpower deputation for general Capex activities, E&M support services for landscaping works in landside and airside areas, manpower deployment for landside building operations, and manpower supply for baggage handling and other operational support functions.

5.6.113. The Aeronautical Manpower Hire expense approved by the Authority and submitted by GHIAL for True up for

the Third Control Period are provided in the table below:

Consultation Paper No: 02/2026-27 Page 104 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.6.114. The Authority notes that the Aeronautical Manpower Hire expenses submitted by GHIAL in respect of the Third Control Period, as part of the Multi-Year Tariff Proposal ("MYTP") for the Fourth Control Period, are approximately 68.60% higher than the Aeronautical Manpower Hire expenses approved by the Authority in the Tariff Order for the Third Control Period. The said variance has been verified by the Authority with reference to the relevant documents furnished by GHIAL, including the certificates issued by the Statutory Auditors / Chartered Accountants ("CA Certificates").

5.6.115. Having regard to the materiality of the said variance, the Authority sought further clarification from GHIAL with respect to the deviation between the Aeronautical Manpower Hire expenses approved by the Authority in the Tariff Order for the Third Control Period and the actual expenses incurred by the Airport Operator during the said period, for the purposes of detailed examination.

5.6.116. The Authority, upon detailed examination of the submissions made by GHIAL and the supporting documentation furnished in respect thereof, identifies the following structural and operational factors as the drivers underlying

the higher Aeronautical Manpower Hire expenses incurred during the Third Control Period:

(i) Contractual Escalations Linked to Statutory Minimum Wages: The Authority notes that the underlying contracts pursuant to which outsourced personnel are deployed at Rajiv Gandhi International Airport, Hyderabad ("RGIA"), incorporate annual escalation clauses ranging between 5% and 8% per annum, the said escalations being aligned with the periodic revisions in the applicable statutory minimum wages notified by the Central / State Governments from time to time. The said escalations are contractually binding, statutorily anchored, and exogenous to the control of GHIAL, and have, over the course of the Third Control Period, contributed materially to the cumulative increase in the said expense head.

(ii) Expansion in Airport Operations: The Authority notes that the Third Control Period has witnessed a substantial expansion in the operational scale of RGIA, on account of the increase in terminal capacity, passenger throughput, ATM volumes, and operational complexity at the Airport. The said expansion has objectively necessitated the augmentation of outsourced manpower deployment across operational, security, and passenger-facing functions, and has consequently resulted in a structural and irreversible increase in the said expense head, commensurate with the enhanced operational footprint of the Airport.

(iii) Implementation of Digi Yatra Services pursuant to MoCA Mandate: The Authority notes that, pursuant to the "Digi Yatra" initiative introduced by the Ministry of Civil Aviation, Government of India ("MoCA") during the Third Control Period, GHIAL has been required to implement and operationalise the Digi Yatra framework at RGIA, the said implementation entailing incremental Manpower Hire Charges of approximately ₹12 Crores per annum, with effect from FY 2024-25. The Authority is of the view that the costs incidental to the said initiative are bona fide operational expenses incurred by GHIAL in compliance with a Government of India mandate, and constitute a legitimate driver of the higher expense incurred during the Third Control Period.

(iv) Deployment of General Capex Monitoring Personnel: The Authority observes that, in view of the substantial scale and complexity of General Capital Expenditure undertaken at RGIA during the Third Control Period, GHIAL engaged GMR Airports Developers Limited (“GADL”) for deployment of a dedicated team of sixteen (16) personnel for monitoring, technical oversight, coordination and execution support in respect of various capex projects. GHIAL submitted that the said deployment entailed an incremental annual expenditure of approximately ₹5.40 Crores. The Authority notes that the said expenditure was in addition to the Project Management Consultancy (“PMC”) deployed for the Southern Precinct Expansion project. The Authority further observes that this expenditure was not directly attributable to any

Consultation Paper No: 02/2026-27 Page 105 of 308TRUE UP FOR THE THIRD CONTROL PERIOD specific asset/project capitalized during the Third Control Period. Accordingly, GHIAL treated the same as part of Operating Expenditure instead of capitalizing it as part of project cost.

5.6.117. The Authority has examined the submission of GHIAL and notes that, given the scale of capex undertaken at RGIA during the Third Control Period, deployment of dedicated personnel for general monitoring, technical oversight and execution coordination was in the nature of enhanced project governance and execution oversight.

Since the expenditure was incurred for general monitoring and coordination of multiple capex projects and was not linked to any specific capital asset, the Authority considers the treatment of the same under Operating Expenditure to be appropriate for the purpose of true-up of the Third Control Period..

5.6.118. The Authority notes that the Manpower Hire Charges for the Third Control Period had been projected on the basis of a base year figure of ₹37.53 Crores, the said base year being FY 2020-21, viz., a financial year materially impacted by the COVID-19 pandemic, during which the operational footprint of the Airport, including the deployment of outsourced manpower, stood temporarily moderated on account of the disruption in airport operations. The Authority further observes that, in the immediately preceding pre-pandemic financial year, the actual expenses incurred under this head amounted to ₹43.75 Crores, the said figure being more reflective of the steady-state pre-pandemic operating profile of the Airport. The post-pandemic normalisation of airport operations during the Third Control Period, accompanied by the resumption and subsequent expansion of operational scale at RGIA, has resulted in the said expense reverting to, and progressively exceeding, the pre-pandemic baseline.

5.6.119. The Authority is, therefore, of the considered view that the actual incurrence of Aeronautical Manpower Hire expenses during the Third Control Period is reflective of the true operational manpower requirements at RGIA, particularly having regard to (i) the contractually mandated annual escalation in line with periodic revisions in the applicable statutory minimum wages; (ii) the expansion in airport operations, including the increase in terminal capacity and passenger throughput during the said period; and (iii) the incremental manpower requirements arising from regulatory mandates such as the implementation of Digi Yatra services and the monitoring of General Capex initiatives.

5.6.120. In line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, the Authority proposes to allocate the Manpower Hire expenses incurred on by GHIAL during the Third Control Period on the basis of the GFA ratio.

5.6.121. Based on the foregoing, Aeronautical Manpower Hire expense proposed to be considered by the Authority for

the Third Control Period is shown in the table below:

Table 93: Aeronautical Manpower Hire expense proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Manpower Hire expense 46.53 41.33 53.46 85.26 87.16 313.73

5.6.122. The Authority notes that GHIAL has submitted total Manpower Hire expense of Rs. 328.75 Crores (ref. Table

70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Manpower Hire expense as per GHIAL is Rs. 312.10 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Manpower Hire expense attributable to aeronautical services has been computed at Rs. 313.73 Crores (ref. Table 93). In this context, it is pertinent to note that the reclassification of CGF services

Consultation Paper No: 02/2026-27 Page 106 of 308TRUE UP FOR THE THIRD CONTROL PERIOD from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

Housekeeping Expenses

5.6.123. The Aeronautical Housekeeping expenses approved by the Authority for the Third Control Period and submitted

by GHIAL for True up are provided in the table below:

Table 94: Comparison of Housekeeping expense as submitted by GHIAL for True up and as approved by the Authority in the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Housekeeping Expenses approved by

5.6.124. The Authority notes that the Aeronautical Housekeeping Expenses submitted by GHIAL for the Third Control Period is ~29.6% lower than the Aeronautical Operating Expenses approved by the Authority in the Third Control Period and the same has also been verified through relevant documents including CA certificates.

5.6.125. The Authority notes that the housekeeping expenses submitted by GHIAL for FY26 reflect an increase of ~48% as compared to FY25. On examination of the submissions made by the Airport Operator, the Authority observes that the said increase is primarily attributable to the factors set out hereunder.

• The Authority notes that, although the 34 MPPA terminal expansion at Rajiv Gandhi International Airport, Hyderabad ("RGIA") was commissioned during FY24, the housekeeping contracts in respect of the expanded terminal interiors were awarded only during FY25 and remained operative for a limited duration of approximately three months in the said fiscal year. Consequently, only a partial cost impact of the said contracts was reflected in the housekeeping expenses for FY25 • The Authority further notes that the full annualised cost of the housekeeping contract for the expanded terminal amounting to approximately Rs. 9 Crore has been reflected in the housekeeping expenses for FY26.

• In addition to the above, the Authority notes that GHIAL has incurred an amount of approximately Rs. 9 Crore during FY 2025–26 towards a one-time deep cleaning activity carried out across the existing (legacy) terminal areas, with a view to aligning the hygiene and service standards thereof with those of the newly commissioned expanded facility.

5.6.126. The Authority, in line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, proposes to allocate the Housekeeping expenses incurred on by GHIAL during the Third Control Period on the basis of the GFA ratio.

5.6.127. Based on the foregoing, Aeronautical Housekeeping expense proposed to be considered by the Authority for the

Third Control Period is shown in the table below:

Consultation Paper No: 02/2026-27 Page 107 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Table 95: Aeronautical Housekeeping expenses proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Housekeeping Expenses 14.15 16.67 26.56 34.86 51.84 144.09

5.6.128. The Authority notes that GHIAL has submitted total Housekeeping expense of Rs. 171.24 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Housekeeping expense as per GHIAL is Rs. 143.73 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Housekeeping expense attributable to aeronautical services has been computed at Rs.

144.09 Crores (ref. Table 95). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

CGF Expense

5.6.129. The CGF Expense approved by the Authority for the Third Control Period and incurred by GHIAL for True up

are provided in the table below:

Table 96: Comparison of CGF expense as incurred by GHIAL for True up and as approved by the Authority in the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total CGF Expense incurred approved by the Authority in

13.20 13.81 14.44 15.11 15.80 72.36 TCP order (A) CGF Cost incurred by the Operator (B) 18.03 21.13 20.84 23.72 27.83 111.55 Variation (B-A) 4.83 7.25 6.4 8.52 11.97 38.96

5.6.130. The Authority notes that the Airport Operator, GHIAL, has not claimed the operating expenses pertaining to Cargo, Ground Handling and Fuel Farm (CGF) operations as part of the aeronautical operating expenditure in its Multi-Year Tariff Proposal (MYTP) for the Fourth Control Period. This stems from the Operator's treatment of the CGF assets as non-aeronautical in nature.

5.6.131. The Authority, however, has examined the said treatment in light of statutory definition and the established regulatory practice for services pertaining to Cargo, Ground Handling and Fuel Farm operations. Accordingly, the Authority proposes that both the revenues earned and the operating expenses incurred in respect of these services are required to be treated as aeronautical in nature for the purpose of tariff determination.

5.6.132. The Authority, at the outset, takes note of the nature of the expense heads under examination:

(a) Fuel Farm (FF) Expenses: Represent the operations and maintenance (O&M) costs payable by GHIAL to the fuel farm operator engaged for the operation of the fuel farm facility at Rajiv Gandhi International Airport, Hyderabad ("RGIA").

Consultation Paper No: 02/2026-27 Page 108 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

(b) Cargo Expenses: Pertain to the managerial and supervisory team deployed by GHIAL in respect of the cargo operations at RGIA.

(c) Ground Handling (BME) Expenses: With effect from FY 2024-25, Ground Handling (BME) services including, Pre-Conditioned Air ("PCA") and Ground Power Unit ("GPU") operations, have been awarded as a service contract by GHIAL to a third-party service provider, having been carried out in-house prior to the said financial year. The said outsourcing has consequently resulted in the said cost being recognised as an external operating expense, in lieu of being absorbed within the manpower and utility cost heads as in the preceding period.

5.6.133. The Authority notes that the Aeronautical Fuel Farm Cost submitted by GHIAL for the Third Control Period in the Multi-Year Tariff Proposal for the Fourth Control Period is higher than the corresponding figure approved by the Authority in the Tariff Order for the Third Control Period. The said expenses have been duly verified by the Authority with reference to the relevant supporting documents furnished by GHIAL, including the certificates issued by the Statutory Auditors / Chartered Accountants ("CA Certificates").

5.6.134. Having regard to the materiality of the variance between the projected and actual figures, the Authority, in the course of its detailed examination, sought further clarification from GHIAL in respect of the underlying drivers contributing to the said variance.

5.6.135. The Authority, upon detailed examination of the submissions made by GHIAL and the supporting documentation furnished in respect thereof, identifies the following structural and operational factors as the drivers underlying

the higher Aeronautical Fuel Farm expenses incurred during the Third Control Period:

(i) Linkage with Operational Drivers -ATMs and Fuel Upliftment: The Authority observes that Fuel Farm expenses, being O&M costs payable to the fuel farm operator, are inherently and directly correlated with the operational throughput at the fuel farm facility, viz., the volume of fuel upliftment at RGIA, which in turn is a function of the Air Traffic Movements ("ATMs") at the Airport. The Authority is of the considered view that the said expense head bears a direct cost-causation link with the operational scale of the Airport, and accordingly, is sensitive to growth in ATM volumes and fuel throughput.

(ii) Increase in Fuel Upliftment: The Authority observes that the actual Fuel Farm expenses witnessed a significant increase from FY 2022-23 onwards. The said increase is primarily attributable to the increase in fuel upliftment at RGIA by approximately 48% during FY 2022-23, driven by post-pandemic recovery in air traffic and the consequent increase in aircraft fueling activity at the Airport. The Authority notes that Fuel Farm expenses are closely linked to the volume of fuel handled/uplifted at the airport. Higher fuel upliftment results in increased operational requirements, including higher utilisation of fuel hydrant systems, pumps, filters, storage and dispensing infrastructure, increased manpower deployment, higher electricity consumption, enhanced maintenance of equipment, additional consumables, testing and quality control, safety inspections, statutory compliance and related O&M activities. Therefore, an increase in fuel throughput has a direct bearing on the operating and maintenance costs of the Fuel Farm. The Authority further observes that the increase in fuel upliftment reflects the recovery and growth in aircraft movements and airline operations at RGIA after the pandemic period. Accordingly, the corresponding increase in Fuel Farm O&M expenses is considered to be in line with the higher scale of operations and the increased throughput handled by the Fuel Farm facility during the Third Control Period.

(iii) Ageing of Vehicles and Equipment: The Authority observes that the vehicles and equipment deployed for Fuel Farm operations have, over the course of the Third Control Period, progressively aged, resulting in higher maintenance costs, particularly during FY 2025-26. The said increase in maintenance expenditure is operationally inevitable and is consistent with the typical lifecycle cost profile of fuel farm equipment.

Consultation Paper No: 02/2026-27 Page 109 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

(iv) Post-Pandemic Normalisation and Expansion of Operations: The Authority observes that the base year figure of ₹12.62 Crores considered for projecting the Fuel Farm expenses for the Third Control Period corresponded to a COVID-19-impacted financial year, during which the operational throughput at the fuel farm facility stood temporarily moderated on account of the disruption in airport operations. With the post- pandemic normalisation and subsequent operational expansion at RGIA, the said expense has progressively reverted to, and exceeded, the pre-pandemic baseline of ₹18.29 Crores, in line with the structural growth of the Airport's fueling activity.

5.6.136. The Authority observes that the cumulative effect of the foregoing factors ,viz., (i) the inherent linkage of the said expense head with operational throughput; (ii) the substantial increase in fuel upliftment in the post-pandemic period; (iii) the lifecycle-driven increase in maintenance costs of fuel farm vehicles and equipment; and (iv) the post-pandemic normalisation and expansion of operations, is reflective of a structural and operationally warranted, increase in the Aeronautical Fuel Farm expenses during the Third Control Period. The said expenses, having been duly substantiated by Chartered Accountant certificates and supporting documentation, are accordingly found to be prudent and justifiable.

5.6.137. The Authority further notes that the expenses pertaining to Cargo, Ground Handling and Fuel Farm operations, as submitted by GHIAL in its MYTP, are aeronautical in nature. Based on the foregoing and rationalization of the expense heads and their CGF component, the Authority proposes to consider the said expenses on actuals as per

table below:

Table 97: CGF Cost proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total CGF Cost 18.03 21.06 20.84 23.63 27.77 111.32 Operating Expenses

5.6.138. The Authority has analyzed GHIAL's submissions regarding Other Operating cost for the Third Control Period.

Operating expenses relate to day-to-day operational support services provided by various operators, including the GA Terminal Operator and Car Park Operator.

5.6.139. The Aeronautical operating expenses approved by the Authority for the Third Control Period and submitted by

GHIA for True up are provided in the table below:

5.6.140. The Authority notes that the Aeronautical Operating Expenses submitted by GHIAL for the Third Control Period in the MYTP for the Fourth Control Period is lower than the Aeronautical Operating Expenses approved by the Authority in the Third Control Period.

Consultation Paper No: 02/2026-27 Page 110 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.6.141. The said lower incurrence is reflective of the operational efficiencies achieved by GHIAL during the Third Control Period, and the same has been duly verified by the Authority with reference to the relevant supporting documents, including the Chartered Accountant Certificates furnished by GHIAL.

5.6.142. The Authority in line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, proposes to allocate the Operating expenses incurred on by GHIAL during the Third Control Period on the basis of the Aero-Non Aero Expense ratio.

5.6.143. Based on the above, Aeronautical Operating expense proposed to be considered by the Authority for the Third

Control Period is shown in the table below:

Table 99: Aeronautical Operating expenses proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Operating Expenses proposed to be

6.52 4.47 5.86 4.56 2.85 24.26 considered by the Authority

5.6.144. The Authority notes that GHIAL has submitted total Operating Expenses of Rs. 135.70 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Operating Expenses as per GHIAL is Rs. 23.11 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Operating Expenses attributable to aeronautical services has been computed at Rs. 24.26 Crores (ref.

Table 99). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

5.6.145. The Aeronautical Operating Expenses proposed to be considered by the Authority for the Third Control Period are marginally higher than GHIAL's submission on account of segregation of common Operating Expenses based on the Aero–Non-Aero Expense Ratio determined by the Authority, which is higher than the ratio submitted by GHIAL due to reclassification of certain expenses based on AERA principles, including treatment of Cargo, Ground Handling and Fuel Farm (“CGF”) expenses.

Collection Charges

5.6.146. The Collection charge incurred by GHIAL in the Third Control Period submitted by GHIAL in the MYTP for

the Fourth Control Period are provided in the table below:

5.6.147. The Authority observes that the Collection Charges payable by GHIAL pertain to the commission paid to airlines towards the collection of User Development Fee ("UDF") from departing passengers, the said expense being directly linked to the embarking passenger traffic at Rajiv Gandhi International Airport, Hyderabad ("RGIA").

The said charges are, by their very nature, traffic-driven, and are incurred in the ordinary course of UDF collection on behalf of GHIAL.

5.6.148. The Authority considers collection charges (UDF) as entirely aeronautical and proposes to consider collection charges as per operator’s submission.

5.6.149. Based on the above, Aeronautical Other Operating Cost proposed to be considered by the Authority for the Third

Control Period is shown in the table below:

The Authority notes that the Aeronautical General Administration Expenses submitted by GHIAL for the Third Control Period in the Multi-Year Tariff Proposal for the Fourth Control Period are higher (~88.3%) than the corresponding figure approved by the Authority in the Tariff Order for the Third Control Period. The said expenses have been duly verified by the Authority with reference to the relevant supporting documents furnished by GHIAL, including the certificates issued by the Statutory Auditors / Chartered Accountants ("CA Certificates").

Consultation Paper No: 02/2026-27 Page 112 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.6.153. Having regard to the materiality of the variance between the projected and actual figures, the Authority has examined the variance between the General Administration Expenses approved in the Tariff Order for the Third Control Period and the actual expenses incurred by GHIAL during the said period, and has identified the following

structural and operational factors as the principal drivers underlying the said variance:

(i) Post-Pandemic Normalisation of General Administrative Activities: The Authority observes that the base year considered for the projection of General Administration Expenses for the Third Control Period corresponded to a COVID-19-impacted financial year, during which several routine general administrative activities, travel and conveyance, business meetings and conferences, training and development, printing and stationery, and ancillary office expenses, stood temporarily moderated on account of the disruption in airport operations. With the post-pandemic normalisation of operations at Rajiv Gandhi International Airport, Hyderabad ("RGIA"), the said expenses have progressively reverted to, and progressed in line with, the steady-state operating profile of the Airport.

(ii) Expansion in Operational Scale of the Airport: The Authority observes that the Third Control Period has witnessed a substantial expansion in the operational scale of RGIA on account of the increase in terminal capacity, passenger throughput, ATM volumes, manpower deployment, and operational complexity at the Airport. The said expansion has objectively necessitated a commensurate scaling-up of general administrative activities required to support the larger operational footprint, and has correspondingly resulted in a structural increase in the said expense head.

(iii) Difference in Cost Allocation Methodology: The Authority observes that, in the Tariff Order for the Third Control Period, certain components of General Administration Expenses viz., travelling expenses and legal consultancy expenses, were classified as Aeronautical to the extent of 50%, on the basis of a direct identification approach. By contrast, the cost figures submitted by GHIAL in the Multi-Year Tariff Proposal for the Fourth Control Period have been classified as Aeronautical on the basis of the Gross Fixed Assets ("GFA") ratio applied to the said cost heads. The Authority observes that the said differential in classification methodology has, in part, contributed to the variance between the approved and submitted figures.

5.6.154. The Authority's examination of the various expense heads classified under General Admin Expenses is set out in

the below paragraphs:

A. Professional and Consultancy Expenses:

5.6.155. The professional and consultancy services are towards the various services availed from the external parties and

includes the following expenses: a. Technical Services from Consultants b. Retainer Fee various expertise personnel c. Placement Fee / Fee for recruitments d. Audit Services such as Internal Audit, Secretarial Audit etc., e. Training Fee paid to various consultants f. Legal Expenses g. Outsourcing Expenses etc.,

5.6.156. The Aeronautical Professional and Consultancy expenses as submitted by GHIAL in the MYTP for the Fourth

Control Period are provided in the table below:

Consultation Paper No: 02/2026-27 Page 113 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Table 103: Aeronautical Professional and Consultancy expenses submitted by GHIAL for the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Professional and Consultancy expenses

13.64 36.33 32.65 40.87 32.48 155.97 submitted by GHIAL

5.6.157. The Authority also notes the considerable increase in expenses in FY 2023 which is attributable to a series of strategic, operational, safety and technology-driven initiatives undertaken by GHIAL.

5.6.158. The Authority further submits that consultancy charges towards legal consultants constituted a significant portion

of Professional and Consultancy expenses as mentioned below:

Table 104: Proportion of Legal Charges in Professional and Consultancy Expenses in the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Total Professional and Consultancy expenses incurred

16.73 45.71 36.48 46.66 37.61 183.19 by GHIAL (A) Legal Consultancy charges forming part of Professional and Consultancy expenses as 4.33 17.35 4.24 2.71 2.38 31.01 submitted by GHIAL (B) % of Professional and Consultancy expenses (B/A) 25.88% 37.95% 11.66% 5.80% 6.32% 16.92%

5.6.159. The Authority also notes that the Legal expenses incurred by GHIAL during FY 2022–23 reflect a considerable increase, which has been attributed by the Airport Operator to advisory services rendered, and matters pertaining to Indirect Taxes, Direct Taxes, proceedings before the Authority, various pending writ petitions, matters relating to Passenger Service Fee ("PSF"), proceedings before the Competition Commission of India ("CCI"), and other related legal matters.

5.6.160. The Authority recalls that, in the Tariff Order for the Third Control Period, it had been specifically provided that Legal expenses, forming part of Professional and Consultancy expenses, shall be allowed only to the extent the same are incurred for purposes related to Aeronautical Services, and shall be subject to the tests of efficiency and necessity of incurrence.

5.6.161. Having regard to the Aeronautical Legal Expenses claimed by GHIAL, the Authority sought a detailed break-up of the legal expenses attributable to Aeronautical Services, along with the underlying basis of allocation as between Aeronautical and Non-Aeronautical Services, for the purposes of detailed examination.

5.6.162. GHIAL in its response submitted that:

(i) The legal expenses incurred during the Third Control Period pertain, inter alia, to AERA-related regulatory matters, Goods and Services Tax (GST), Service Tax, Income Tax matters, and other routine litigation and advisory engagements.

(ii) The fees payable to Senior Advocates are governed by established professional norms and confidentiality considerations, and accordingly, detailed disclosures in respect of such fees are not feasible.

(iii) The legal expenses incurred comprise a combination of case-specific fees and retainer arrangements covering multiple matters concurrently. Given the nature and scope of the said engagements, it is not

Consultation Paper No: 02/2026-27 Page 114 of 308TRUE UP FOR THE THIRD CONTROL PERIOD practicable to segregate or apportion such expenses across Aeronautical and Non-Aeronautical Services with precision.

(iv) The said legal expenses have been incurred primarily in connection with safeguarding and enforcing GHIAL's rights and obligations under the Concession Agreement, the said rights being intrinsically linked to the provision and regulation of Aeronautical Services at Rajiv Gandhi International Airport, Hyderabad ("RGIA"). Accordingly, GHIAL has submitted that the said expenses ought to be classified as Aeronautical in nature for regulatory purposes.

5.6.163. The Authority observes that the detailed break-up of the Legal expenses attributable to Aeronautical Services has not been furnished by GHIAL. In the absence of the requisite information, the Authority proposes to allocate the Legal expenses on the basis of the ratio of Aeronautical Revenue to the total income of GHIAL in the respective financial years, as set out in the table hereunder:

Table 105: Proportion of Aero Revenue to Total Income of GHIAL for the Third Control Particular FY22 FY23 FY24 FY25 FY26 Proportion of Aero Revenue to Total Income 49.71% 55.34% 62.93% 66.17% 72.15%

5.6.164. The legal expenses proposed to be considered by the Authority based on the above allocation methodology is

as follows:

2.15 9.60 2.67 1.79 1.71 17.92 considered by the Authority

5.6.165. Based on the analysis, the Aeronautical Professional and Consultancy charges proposed to be considered by the

Authority for the Third Control Period are provided below:

Table 107: Aeronautical Professional & Consultancy charges proposed by the Authority for True up of the Third Control Period (Rs.

5.6.166. The recruitment charges are payment made towards the recruiting agency of the newly joined employees.

5.6.167. The Aeronautical recruitment charges as submitted by GHIAL in the MYTP for the Fourth Control Period are

provided in the table below:

Consultation Paper No: 02/2026-27 Page 115 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Table 108: Aeronautical Recruitment Charges submitted by GHIAL for the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical recruitment charges submitted by

0.33 1.98 2.42 5.24 4.28 14.26 GHIAL

5.6.168. The Authority observes that, under the prevailing recruitment service arrangements, GHIAL is liable to pay to the recruitment agency a fee ranging between a minimum of two (2) months' and a maximum of six (6) months' salary of the newly recruited employee, the precise quantum within the said range being determined with reference to the category and seniority of the recruited employee, computed on the basis of the agreed Cost-to-Company ("CTC") of the said employee.

5.6.169. The Authority further observes that the level of Recruitment Charges incurred during the Third Control Period is reflective of the substantial manpower augmentation that became operationally imperative during the said period, on account of phased commissioning of the 34 MPPA terminal expansion, capitalised in FY 2023-24, the cost of which is reflected in the higher Recruitment Charges incurred during the said period.

5.6.170. The Authority in line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, proposes to allocate the common recruitment charges incurred on by GHIAL during the Third Control Period on the basis of the Aero-Non Aero Expense ratio.

5.6.171. The Aeronautical recruitment charges proposed to be considered by the Authority for the Third Control Period

are provided below:

Table 109: Aeronautical Recruitment Charges proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Recruitment Charges 0.37 2.19 2.54 5.45 4.50 15.04

5.6.172. The Authority notes that GHIAL has submitted total Recruitment Charges of Rs. 16.41 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Recruitment Charges as per GHIAL is Rs. 14.26 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Recruitment Charges attributable to aeronautical services has been computed at Rs.

15.04 Crores (ref. Table 109). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

C. Printing & Stationery

Consultation Paper No: 02/2026-27 Page 116 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.6.173. The Aeronautical Printing & Stationery expenses as submitted by GHIAL in the MYTP for the Fourth Control

Period are provided in the table below:

Table 110: Aeronautical Printing & Stationery Expense submitted by GHIAL for the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Printing & Stationery expenses

0.35 0.42 0.94 0.59 0.62 2.91 submitted by GHIAL

5.6.174. The Authority observes that the increase in the said expense head during FY 2023-24 is principally attributable to a corresponding increase in the cost of Security & Vigilance stationery and other consumables at the Airport.

The said increase is reflective of the scaling-up of security and vigilance operations consequent upon the phased commissioning of the 34 MPPA terminal expansion during FY 2023-24, which materially augmented the operational footprint and the security perimeter requiring active vigilance

5.6.175. The Authority in line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, the Authority proposes to allocate the Printing & Stationery expenses incurred on by GHIAL during the Third Control Period on the basis of the GFA ratio.

5.6.176. The Aeronautical Printing & Stationery expenses proposed to be considered by the Authority for the Third

Control Period are provided below:

Table 111: Aeronautical Printing & Stationery Expense proposed by the Authority for True up of the Third Control period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Printing & Stationery expenses 0.36 0.42 0.95 0.59 0.63 2.95

5.6.177. The Authority notes that GHIAL has submitted total Printing & Stationery expense of Rs. 3.31 Crores (ref. Table

70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Printing & Stationery expense as per GHIAL is Rs. 2.91 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Printing & Stationery expense attributable to aeronautical services has been computed at Rs. 2.95 Crores (ref. Table 111). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges.

Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

D. Travelling and Conveyance

5.6.178. The Authority analyzed GHIAL’s submission regarding Travelling and Conveyance expenses for the Third Control Period. Travelling and Conveyance expenses comprise expenses pertaining to Local Conveyance, Travel Charges for the employees (Domestic / Foreign) and Chartering Costs for senior management of GHIAL.

Consultation Paper No: 02/2026-27 Page 117 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.6.179. The Aeronautical Travelling and Conveyance expenses as submitted by GHIAL in the MYTP for the Fourth

Control Period are provided in the table below:

Table 112: Aeronautical Travelling and Conveyance Expense submitted by GHIAL for the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Travelling and Conveyance expenses

22.92 31.60 39.42 41.44 38.62 174.01 submitted by GHIAL

5.6.180. The Authority, upon detailed examination of the Travelling and Conveyance Expenses incurred by GHIAL during the Third Control Period, observes that the said expense head is predominantly attributable to business travel, the said component constituting approximately 78% of the total cost incurred. The balance of the said expense pertains to employee transportation and ancillary travel-related costs.

5.6.181. The Authority notes that the Aeronautical Travelling & Conveyance expenses of Rs. 174.01 Crores have been computed by GHIAL by considering aeronautical component of Rs. 12.83 Crores which is directly attributable to aeronautical services and the balance common component of Rs. 188.90 Crores apportioned into aeronautical and non-aeronautical using the Gross Fixed Assets (GFA) ratio as per Table 64.

5.6.182. The Authority notes that the Travel Costs incurred by GHIAL cannot be accurately segregated between Aeronautical and Non-Aeronautical Services on the basis of direct identification.

5.6.183. Accordingly, and consistent with the approach adopted in past tariff determinations, the Authority proposes to allocate the common Travelling & Conveyance Costs incurred by GHIAL during the Third Control Period between the Aeronautical and Non-Aeronautical in the ratio of 50:50.

5.6.184. Based on the foregoing, the Aeronautical Travelling and Conveyance expenses proposed to be considered by the

Authority for the Third Control Period are provided below:

Table 113: Aeronautical Travelling and Conveyance Expense proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aero Cost (A) 1.13 1.77 2.92 3.29 3.73 12.83 Common Cost (B) 26.46 36.76 41.63 43.73 40.32 188.90 Total Aeronautical Travelling and Conveyance

14.36 20.15 23.73 25.15 23.89 107.28 expenses (A+B*50%) E. Communication Cost

5.6.185. The Authority notes that Communication costs include the Leased Line Charges/VPN for GHIAL administration purposes across RGI airport, mobile expenses for operating staff. These costs are non-recoverable from any concessionaires.

5.6.186. The Aeronautical Communication Cost as submitted by GHIAL in the MYTP for the Fourth Control Period are

provided in the table below:

Consultation Paper No: 02/2026-27 Page 118 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Table 114: Aeronautical Communication Expense submitted by GHIAL for the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Communication Cost submitted by

2.02 2.02 1.7 1.86 1.91 9.51 GHIAL

5.6.187. In line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, the Authority proposes to allocate the Communication expenses incurred on by GHIAL during the Third Control Period on the basis of the GFA ratio.

5.6.188. The Aeronautical Communication Cost proposed to be considered by the Authority for the Third Control Period

are provided below:

Table 115: Aeronautical Communication Cost proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Communication Cost 2.09 2.05 1.71 1.87 1.94 9.66

5.6.189. The Authority notes that GHIAL has submitted total Communication cost of Rs. 10.81 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Communication cost as per GHIAL is Rs. 9.51 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Communication cost attributable to aeronautical services has been computed at Rs. 9.66 Crores (ref.

Table 115). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

F. Advertising and Sales Promotion

5.6.190. The Aeronautical Advertising and Sales Promotion expenses as submitted by GHIAL in the MYTP for the Fourth

Control Period are provided in the table below:

Table 116: Aeronautical Advertising and Sales Promotion expenses submitted by GHIAL for the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Advertising and Sales Promotion

4.98 6.07 13.26 18.63 13.75 56.69 expenses submitted by GHIAL

5.6.191. The Authority has examined the expenses incurred by GHIAL under the head "Advertisement and Business Promotion" during the Third Control Period and the projections proposed for the Fourth Control Period. Upon a detailed review of the nature, purpose, and beneficiary of each activity comprised within this head, the Authority

Consultation Paper No: 02/2026-27 Page 119 of 308TRUE UP FOR THE THIRD CONTROL PERIOD has classified the following sub-heads for the purpose of determining their appropriate treatment within the

aeronautical tariff framework:

Table 117: Classification of Expenses by the Authority under Advertisement & Sales Promotion S. No. Expense Sub-Head Nature Aero Allocation % 1 Business Promotion Common 50% 2 Event Management Expenses Common 50% 3 Guest Protocol Common 50% 4 Gifts & Compliments Non-Aeronautical 0% 5 Advertisement – Others Common 50%

Basis of Allocation:

Business Promotion

5.6.192. The Authority observes that the activities under this head — namely, website maintenance, corporate communication, social media presence, brand visibility of RGIA, stakeholder engagement, sponsorships (sports, tourism, trade), promotional events, and milestone events — serve to enhance the overall brand and reputation of RGIA as a whole, encompassing both its aeronautical and non-aeronautical dimensions. The benefits of these

activities flow to:

(i) Aeronautical users through enhanced airport visibility, route attractiveness, and passenger experience; and

(ii) Non-aeronautical users/concessionaires through increased footfall, brand value of the commercial estate, and visibility for retail/F&B/cargo/real estate activities.

5.6.193. Given that the said expenses are incurred for the joint benefit of aeronautical and non-aeronautical operations and contribute to the holistic brand-building of RGIA, the Authority accordingly determines the allocation as 50% Aeronautical / 50% Non-Aeronautical.

Event Management Expense

5.6.194. The Authority notes that this head comprises a heterogeneous mix of activities which simultaneously cater to aeronautical and non-aeronautical functions of the airport, including:

(i) Aviation industry events (APOC, National Energy Event)

(ii) Festival celebrations (Diwali, New Year), CEO townhalls, internal HR events

(iii) Public engagement initiatives (10K runs, FAB stall events)

5.6.195. Given that the said expenses are commonly incurred for the joint benefit of aeronautical and non-aeronautical operations, and in the absence of a verifiable activity-wise cost driver that would permit a more granular segregation, the Authority considers it just, fair, and reasonable to apportion the cost equally between the two functions. The Authority accordingly determines the allocation as 50% Aeronautical & 50% Non-Aeronautical.

Guest Protocol

5.6.196. The Authority observes that guest protocol expenses (manpower for guest handling, hospitality services, management fees for service providers catering to VIPs, dignitaries, and stakeholders) are extended to two broad

categories of visitors:

(i) Aviation regulators, DGCA officials, airline executives, ICAO/IATA representatives

Consultation Paper No: 02/2026-27 Page 120 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

(ii) Commercial partners, concessionaires, retail/F&B partners, and corporate visitors

5.6.197. As the guest protocol services are availed by aeronautical and non-aeronautical stakeholders without any clear or measurable basis for segregation, the Authority adopts the equal apportionment principle as a transparent and equitable approach. Accordingly, the allocation is determined as 50% Aeronautical and 50% Non-Aeronautical.

Gifts & Compliments

5.6.198. The Authority notes that expenses under this head, comprising mementos, bouquets, books, sweets, and similar items presented to guests, dignitaries, business partners, and stakeholders, are in the nature of corporate goodwill, courtesy, and relationship-building expenditure which is largely discretionary and commercial in character

5.6.199. The Authority notes that such discretionary courtesy expenses do not arise from the discharge of any aeronautical function or obligation and is of the considered view that passengers and airlines should not be made to bear any portion of this cost through the aeronautical tariff. The Authority accordingly determines the allocation as 100% Non-Aeronautical.

Advertisement – Others

5.6.200. The Authority has examined the activities grouped under this head, including sponsorships (CII, India Ideas Conclave), print and outdoor media advertisements, hoarding and branding initiatives, exhibition participation (Wings India), digital marketing (search engine marketing), and art café initiatives. The Authority observes that while certain elements of this expenditure (such as outdoor branding, exhibitions, and digital marketing) are aimed at attracting non-aeronautical patronage (concessionaires, retail tenants, cargo clients, advertisers), other elements (such as participation in aviation exhibitions like Wings India, sponsorships of aviation-linked forums, and digital outreach communicating airport connectivity, route information, and passenger services) also benefit the aeronautical user base by enhancing visibility of RGIA in the aviation ecosystem, communicating route, schedule, and passenger service information to potential travellers and strengthening the airport's positioning as an aviation hub for airlines considering route deployment.

5.6.201. Considering that the activities under this head, taken as a whole, generate dual benefits accruing to both aeronautical and non-aeronautical functions of the airport, the Authority determines the allocation as 50% Aeronautical and 50% Non-Aeronautical.

5.6.202. The Authority further notes that on examination of the sub-components of the said expense, an amount of Rs.

5.04 crore in FY25 towards a "Key Partnership Program" was extended to airlines.

5.6.203. The Authority recalls that during the tariff determination for the Third Control Period, this very issue had come up for consideration. At that time, the Authority had accepted the Voluntary Tariff Proposal (VTP) submitted by GHIAL except for the Key Partnership Program for freighter airlines, on the considered view that the said program was discriminatory in nature, hence the Authority proposes not to consider Rs.5.04 crores for True up.

5.6.204. Based on the foregoing, the Aeronautical Advertising and Sales Promotion expenses proposed to be considered

by the Authority for the Third Control Period are provided below:

Table 118: Aeronautical Advertising and Sales Promotion expenses proposed by the Authority for True up of the Third Control period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Advertising and Sales Promotion

2.48 3.44 5.96 6.91 8.27 27.06 expenses

Consultation Paper No: 02/2026-27 Page 121 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.6.205. The Aeronautical Advertising and Sales Promotion expenses proposed to be considered by the Authority for the Third Control Period is higher than GHIAL’s submission on account of segregation of common Advertisement & Sales expense based on Aero-Non Aero Expense ratio which is higher than the submission of GHIAL due to reclassification of certain expenses based on AERA principles, including treatment of Cargo, Ground Handling and Fuel Farm (“CGF”) expenses.

G. Corporate Cost

5.6.206. The Authority notes that the Corporate Cost arises from shared corporate functions performed by GAL (the holding company) through Centers of Excellence for the multi-airport group, with proportionate allocation to RGIA on a shared services basis.

5.6.207. The corporate cost is primarily driven by manpower costs allocated at the group level, as personnel-related expenses constitute the majority of corporate overhead.

5.6.208. The Aeronautical Corporate Cost as submitted by GHIAL in the MYTP for the Fourth Control Period based on the allocation ratio determined by GHIAL by treating CGF services as non-Aeronautical is provided in the table

below:

Table 119: Aeronautical Corporate Cost as submitted by GHIAL for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Corporate Cost expenses submitted by

28.03 28.60 42.90 53.90 67.38 220.80 GHIAL

5.6.209. The Authority has examined the Corporate Cost Allocation submitted by GHIAL for the Third Control Period, and observes that the said allocation reflects a substantial increase commencing FY 2023-24. The Authority has, accordingly, sought clarification from GHIAL in respect of the underlying drivers contributing to the said increase, for the purposes of detailed examination.

5.6.210. The Authority, upon detailed examination of the submissions made by GHIAL and the supporting documentation furnished in respect thereof, identifies the following structural and operational factors as the drivers underlying the increase in Corporate Cost Allocation from FY 2023-24 onwards:

(i) Augmentation of Group-Level Manpower commensurate with Operational Expansion: The Authority observes that the phased commissioning of the 34 MPPA terminal expansion at Rajiv Gandhi International Airport, Hyderabad ("RGIA"), in FY 2023-24, has resulted in a substantial augmentation of the operational footprint of the Airport, which has, in turn, necessitated a corresponding scaling-up of group-level manpower deployed for shared corporate functions. The said augmentation is bona fide and operationally warranted, having regard to the enhanced governance, oversight, and support requirements occasioned by the expanded operational base.

(ii) Employee-Related Costs: The increase in Corporate Cost Allocation is partly attributable to periodic increments granted to group-level employees in accordance with the prevailing Group Human Resource Policy and the management decisions taken from time to time, the said increments being consistent with prevailing industry compensation practices.

(iii) Establishment of Centers of Excellence: The Authority observes that, with effect from the said period, Centers of Excellence ("CoEs") have been established at the group level for the centralized performance of specialized functions, inter alia, book-keeping, construction management, and master planning. The said CoE model leverages economies of scale and specialization across the group's airport portfolio, and the

Consultation Paper No: 02/2026-27 Page 122 of 308TRUE UP FOR THE THIRD CONTROL PERIOD proportionate allocation of the costs thereof to RGIA is consistent with the shared services framework typically adopted in multi-airport groups.

(iv) Specialized Consultancy Services: The induction of specialized consultancy services at the group level in respect of (a) the impact of climate change on the assets of GMR Airports Limited ("GAL"), in line with evolving sustainability and ESG obligations applicable to infrastructure operators; and (b) the development of slot optimization tools to enhance airside efficiency has contributed to the upward movement in Corporate Cost Allocation. The Authority observes that the said consultancy initiatives are forward-looking and operationally relevant to the long-term sustainability and efficiency of airport operations at RGIA.

(v) Business Promotion and Industry Engagement: Expenditure incurred towards seminars, industry engagement, and high-level forums, including participation in IATA events, investor engagement events, and sponsorship of the World Economic Forum, represents part of the broader effort to position the GMR group's airports, including RGIA, on the global aviation map, and to facilitate strategic engagement with airline partners, investors, and regulators.

(vi) Capability Development Initiatives: Investments in new capability-building initiatives at the group level, in the areas of Master Data Management ("MDM") and digital transformation, are reflective of the growing imperative for digitalization, data integrity, and technology-led operational efficiency in airport operations.

(vii) Recruitment to Fill Vacant Corporate Positions: Recruitment expenditure incurred for filling up of vacant positions at the corporate level is reflective of the manpower augmentation undertaken to support the expanded operational footprint and enhanced governance requirements arising from the commissioning of the 34 MPPA terminal expansion.

5.6.211. The Authority, in line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, the Authority proposes to allocate the Corporate Cost incurred by GHIAL during the Third Control Period on the basis of the Aero-Non Expense ratio.

5.6.212. The Aeronautical Corporate cost proposed to be considered by the Authority for the Third Control Period are

provided below:

Table 120: Aeronautical Corporate Cost proposed to be considered by the Authority for the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Corporate cost 31.48 31.56 45.03 56.08 71.76 235.91

5.6.213. The Authority notes that GHIAL has submitted total corporate cost of Rs. 257.82 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical corporate expense as per GHIAL is Rs. 220.80 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the corporate cost attributable to aeronautical services has been computed at Rs. 235.91 Crores (ref.

Table 120). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase

Consultation Paper No: 02/2026-27 Page 123 of 308TRUE UP FOR THE THIRD CONTROL PERIOD in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

H. Directors Sitting Fee

5.6.214. The Aeronautical Directors Sitting Fee as submitted by GHIAL in the MYTP for the Fourth Control Period are

provided in the table below:

Table 121: Aeronautical Directors Sitting Fee submitted by GHIAL for the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Directors Sitting Fee submitted by

0.14 0.20 0.21 0.16 0.18 0.90 GHIAL

5.6.215. In line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, the Authority proposes to allocate the Director’s Sitting Fee incurred on by GHIAL during the Third Control Period on the basis of the Aero-Non Expense ratio.

5.6.216. Based on the foregoing, the Aeronautical Directors Sitting Fee proposed to be considered by the Authority for the

Third Control Period are provided below:

Table 122: Aeronautical Directors Sitting Fee proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Directors Sitting Fee 0.16 0.22 0.22 0.17 0.19 0.97

5.6.217. The Authority notes that GHIAL has submitted total Directors Sitting Fee of Rs. 1.06 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Directors Sitting Fee as per GHIAL is Rs. 0.90 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Directors Sitting Fee attributable to aeronautical services has been computed at Rs. 0.97 Crores (ref.

Table 122). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

I. Payment to Auditor

5.6.218. The Aeronautical Payment to Auditor as submitted by GHIAL in the MYTP for the Fourth Control Period are

provided in the table below:

Consultation Paper No: 02/2026-27 Page 124 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Table 123: Aeronautical Payment to Auditor submitted by GHIAL for the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Payment to Auditor submitted by

0.49 0.64 0.65 0.70 1.05 3.53 GHIAL

5.6.219. In line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, the Authority proposes to allocate the Payment to Auditor incurred on by GHIAL during the Third Control Period on the basis of the Aero-Non Expense ratio.

5.6.220. Based on the foregoing, the Aeronautical Payment to Auditor proposed to be considered by the Authority for the

Third Control Period are provided below:

Table 124: Aeronautical Payment to Auditor proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Payment to Auditor 0.55 0.70 0.68 0.73 1.12 3.78

5.6.221. The Authority notes that GHIAL has submitted total Payment to Auditor of Rs. 4.23 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Payment to Auditor as per GHIAL is Rs. 3.53 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Payment to Auditor attributable to aeronautical services has been computed at Rs. 3.78 Crores (ref.

Table 124). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

J. Other Admin Expense

5.6.222. The Other Admin Expense as submitted by GHIAL in the MYTP for the Fourth Control Period are provided in

the table below:

Table 125: Aeronautical Other Admin Expense submitted by GHIAL for the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Other Admin Expense submitted by

2.57 2.55 3.56 4.58 5.77 19.03 GHIAL

5.6.223. The Authority notes that the expenses classified by GHIAL under the head "Other Admin Expenses"

comprise the following components: • Membership fees paid to professional bodies such as CAPA (Centre for Aviation), CFO Next, APAO (Association of Private Airport Operators), CEO Next, and similar industry/professional forums;

Consultation Paper No: 02/2026-27 Page 125 of 308TRUE UP FOR THE THIRD CONTROL PERIOD • Subscription charges for books, periodicals, and professional publications; and • Meeting and seminar expenses incurred for internal team meetings and related engagements.

5.6.224. In line with the principles of cost allocation between Aeronautical and Non-Aeronautical activities, and consistent with the approach adopted by the Authority in earlier tariff determinations, the Authority proposes to allocate the Other Admin Expense incurred on by GHIAL during the Third Control Period on the basis of the GFA ratio.

5.6.225. The Aeronautical Other Admin Expense proposed to be considered by the Authority for the Third Control Period

are provided below:

Table 126: Aeronautical Other Admin Expense proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Other Admin Expense 2.65 2.57 3.57 4.61 5.88 19.27

5.6.226. The Authority notes that GHIAL has submitted total Other Admin Expense of Rs. 21.70 Crores (ref. Table 70) and after applying the allocation ratio as determined by GHIAL by treating CGF services as non-aeronautical, the aeronautical Other Admin Expense as per GHIAL is Rs. 19.03 Crores (ref. Table 71). The Authority has reclassified CGF services as aeronautical and accordingly revisited the allocation methodology and recalculated the expense allocation ratio. Based on the revised allocation ratio, which is higher than the allocation ratio considered by GHIAL, the Other Admin Expense attributable to aeronautical services has been computed at Rs.

19.27 Crores (ref. Table 126). In this context, it is pertinent to note that the reclassification of CGF services from non-aeronautical to aeronautical results in revenues from CGF services getting added to aeronautical revenue, ultimately offsetting the Aggregate Revenue Requirement (ARR) thereby reducing aeronautical charges. Though this approach results in some increase in the aeronautical portion of the related opex item but the corresponding increase in the aeronautical revenue provides a substantial benefit to airport users by allowing the full impact of CGF revenue for offsetting aeronautical charges, thereby ensuring consistency in the treatment of costs and revenues.

5.6.227. Based on the foregoing, the Authority proposes to consider General Admin Expense as per the table below:

Table 127: Aeronautical General Admin Expense proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical General Admin Expense 67.83 97.23 117.07 143.26 151.85 577.25 Assets Written off

5.6.228. The Aeronautical Assets Written off as submitted by GHIAL in the MYTP for the Fourth Control Period are

provided in the table below:

Consultation Paper No: 02/2026-27 Page 126 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Table 128: Aeronautical Assets Written off submitted by GHIAL for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Aeronautical Assets Written off submitted by

0.05 0.66 0.88 0.00 0.00 1.59 GHIAL

5.6.229. The Authority notes that the operator has not provided details on the salvage value recovered on account of the assets written off. In view of this the authority proposes to disallow the expenses associated with the assets being written off and may revisit again at the time of issuance of tariff order subject to submission of relevant data by the Airport Operator.

Bad Debts, Provision for Bad Debts, Donations and CSR Expenses:

5.6.230. The expenses for the Third Control Period submitted by GHIAL in the MYTP for the Fourth Control Period are

as follows:

Table 129: Bad Debts, Provision of Bad Debts, Donations and CSR Expenses submitted by GHIAL for the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Total Expenses submitted by GHIAL Bad Debt - 63.00 - - - 63.00 Provision of Bad Debt - - 5.06 1.17 0.15 6.38 Donation & Contribution to Electoral Fund 20.00 - - 7.50 0.85 28.35 CSR 8.20 8.20 8.50 8.50 11.95 45.35 Aero Portion of Expenses submitted by GHIAL Bad Debt - 51.13 - - - 51.13 Provision of Bad Debt - - 4.44 - - 4.44 Donation & Contribution to Electoral Fund 17.63 - - 6.62 0.74 24.99 CSR 6.76 6.65 7.45 7.42 10.34 38.62 CSR

5.6.231. The Authority took cognizance of the statutory provisions of the Companies Act, 2013 towards allowance of

CSR expenses and the extract of the same has been provided below: i. ‘Section 135 (1) of Companies Act, 2013 states that ‘Every company having net worth of rupees five hundred crore or more, or turnover of rupees one thousand crore or more or a net profit of rupees five crore or more during immediately preceding financial year shall constitute a Corporate Social Responsibility Committee of the Board consisting of three or more directors, out of which at least one shall be an independent director.’ Further section 135(5) states that ‘The Board of every company referred in section 135(1), shall ensure that the company spends, in every financial year, at least two percent of the average net profits of the company made during the three immediately preceding financial years, in pursuance of its Corporate Social Responsibility.’

5.6.232. In this regard, the Authority is of the view that the CSR is a mandatory Social Responsibility of the Company (as per Section 135(1) of Companies Act). As the CSR expenditure is to be incurred by Companies out of their net profits, it is to be regarded as an element of appropriation of Net Profits and not as a part of their Operating Expenditure. Therefore, CSR expenses could not be construed as a passthrough expenditure of the companies,

Consultation Paper No: 02/2026-27 Page 127 of 308TRUE UP FOR THE THIRD CONTROL PERIOD otherwise, it would defeat the very purpose of the social responsibility entrusted on the companies. Further,

Section 37(1) of Income Tax Act also disallows CSR expenses, as these are not considered expenses incurred wholly and exclusively for the purpose of business of the entity.

5.6.233. The Authority hence proposes not to consider CSR expenses as part of Aeronautical O&M expenses for the Third Control Period.

Bad Debt

5.6.234. The Authority notes that GHIAL has availed the credit facilities of INR 4,200 Crore from Yes Bank Limited for the terminal expansion CAPEX in December 2019 and had paid 1.5% upfront non-refundable facility fee (INR 63 Crore). The Yes Bank credit facility was offered to GHIAL at 9.95%. However, due to change in the market conditions, GHIAL raised USD 300 Mn (INR 2067 cr) at a coupon rate of 5.375% + hedge cost in April 2019 (Effective cost of 9.96% plus Withholding tax). GHIAL further raised USD 300 Mn (INR 2,188 cr) in February 2021 at a coupon rate of 4.75% + hedge cost (Effective cost of 9.39% plus Withholding tax). The blended FCB rate including withholding tax was around 10.10%.

5.6.235. The Authority notes that although GHIAL availed the credit facility from Yes Bank but never drew the fund from it. Further, GHIAL opted to avail the FCBs with a blended rate of 10.10% vis-à-vis the Yes Bank credit facility of 9.95% (YBL MCLR + 0.10%) in order to manage their cashflows for repayment of the loan, which doesn’t have any direct bearing on the airport users and is solely a business decision. Therefore, the Authority is of the view that the Airport Users will not accrue any benefit on account GHIAL availing FCDs instead of the Yes Bank Credit facilities and may lead to a higher weighted average cost of debt for the calculation of Weighted Average Cost of Capital.

Donation to Electoral Fund

5.6.236. The Authority is of the considered view that donations to electoral funds, electoral bonds, or any form of political contributions cannot be treated as a legitimate cost recoverable through the aeronautical tariff, for the following

reasons:

(i) No Nexus with Aeronautical Service Delivery: Such contributions have no demonstrable connection with the provision of aeronautical services to airlines, passengers, or cargo operators. They neither contribute to the operations, maintenance, or development of the airport infrastructure, nor enhance the quality of aeronautical services rendered to the users.

(ii) Discretionary and Voluntary in Nature: Donations of this nature are wholly discretionary and voluntary acts of the corporate entity, undertaken in pursuit of considerations extraneous to the regulated aeronautical business. They do not arise from any statutory obligation, regulatory mandate, or operational necessity associated with the running of the airport.

5.6.237. Further, the Authority consistent with the decision taken in the past proposes not to consider Bad debt, Donations and Provisions for Bad Debts as part of Aeronautical O&M expenses for the Third Control Period.

Utility Expenses

5.6.238. The Utility expenses submitted by GHIAL and as approved by the Authority in the Tariff Order for the Third

Control Period is as follows:

Consultation Paper No: 02/2026-27 Page 128 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Table 130: Comparison of Utility expenses as submitted by GHIAL for True up and as approved by the Authority in the Third Control Period (Rs.

5.6.239. The Authority notes that the Utility expenses submitted by GHIAL for the Third Control Period in the MYTP for the Fourth Control Period is ~30.9% lower than the Utility Expenses approved by the Authority in the Third Control Period and the same has also been verified through relevant documents including CA certificates.

5.6.240. The Authority has analyzed the utility consumption of GHIAL along with the Utility charges submitted by

GHIAL towards true up for the Third Control Period:

Consultation Paper No: 02/2026-27 Page 129 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.6.241. The Authority further notes that the percentage of utility cost recovery from concessionaires has registered a noticeable improvement during FY26 as compared to the preceding year. Electricity recovery has increased to

55.32% in FY26 from 48.14% from the previous year and water recovery has increased to 33.62% in FY26 from

27.09% in FY25.

5.6.242. The Authority notes that the Utility expense submitted by GHIAL for the Third Control Period is lower than the Utility expense approved by the Authority in the Third Control Period and the same has also been verified through relevant documents including CA certificates and is found to be reasonable. Further it is submitted that the independent consultant has verified the necessary recoveries from various concessionaires and found that such recoveries are netted off from the above utility expenses.

5.6.243. The Authority has examined the submission made by GHIAL with respect to the Utility Expenses (comprising Electricity and Water charges) incurred during the Third Control Period (FY22-FY25) and the actuals for FY26, as detailed in table above. The Authority notes that the Utility Expenses reflected in the said table represent the net expenses borne by GHIAL after recovery of the proportionate utility charges from concessionaires, commercial occupants, and other third-party users of the airport infrastructure.

5.6.244. The Authority has reviewed the consumption pattern of electricity over FY22-FY26 and notes that while the total electricity demand at RGIA has more than doubled between FY22 and FY26 (largely on account of post-COVID traffic recovery and ongoing capacity expansion), the captive solar generation has remained largely stagnant, registering a growth of merely ~6% over the same period.

5.6.245. Based on the above, Aeronautical Utility expense proposed to be considered by the Authority for the Third Control

Period is shown in the table below:

Table 132: Aeronautical Utility expense proposed by the Authority for True up of the Third Control Period (Rs. In crores) FY ending March FY22 FY23 FY24 FY25 FY26 Total Utility expense proposed to be considered by the

5.6.247. The Authority notes that the Aeronautical Concession Fee submitted by the Operator for the Third Control Period actuals is lower than the amount approved by the Authority in the Third Control Period Tariff Order, the said variance being attributable solely to the divergent treatment of revenues from Cargo, Ground Handling and Fuel Farm (CGF) operations, while the Operator has classified CGF revenues as non-aeronautical and has

Consultation Paper No: 02/2026-27 Page 130 of 308TRUE UP FOR THE THIRD CONTROL PERIOD consequently excluded them from the aeronautical revenue base for computation of the Concession Fee, the Authority treats CGF revenues as aeronautical in nature.

5.6.248. Based on the treatment suggested, the concession fees has been calculated as 4% of the revised aeronautical

revenues as shown in the table below:

Table 134: Aeronautical Concession Fee proposed to be considered by the Authority for the Third Control Period (Rs. In crores) Particulars (In Rs.

5.6.249. The Aeronautical Concession Fee proposed to be considered by the Authority for the Third Control Period is higher than GHIAL’s submission on account of treatment of CGF revenue and MRO revenue as aeronautical revenue.

Strategic, Management and Technical Service Fee

5.6.250. The Authority took note of GHIAL’s submission regarding a new expense head, Strategic, Management and Technical Service Fee, proposed for the last financial year of the Third Control Period.

5.6.251. The Authority sought clarification from GHIAL on the details and justifications for projection of such expenses for the last financial year of the Third Control Period. GHIAL’s responses are as follows:

5.6.252. “GHIAL Board in its meeting dated 23.07.2025, has approved the payment of Strategic, Management and Technical Service Fee from FY26 to all its shareholders including GMR Airports Limited (GAL), Airport Authority of India and Government of Telangana. The Clauses 3.4 and 3.5 of the Shareholders Agreement defines the Role of the Sponsors which lists down the various activities that the Sponsors are to provide.

The Clause 5.10 of the Shareholders Agreement provides that all decisions of the Board shall be a simple majority of the Directors present and voting. The Clause 11.3 of the Shareholders Agreement mentions that GHIAL shall provide to each of its investors with a right to consult and advise management of GHIAL on various issues.

Consultation Paper No: 02/2026-27 Page 131 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.6.253. Hence the board of GHIAL has now decided to start paying, going forward, a consideration for the services being provided by shareholders to the Company towards its strategic leadership, governance and business sustainability @3% of stand-alone gross revenue from FY 2026 on a quarterly basis.”

5.6.254. The Authority notes that, as per the present shareholding pattern of GHIAL, 26% of the shareholding is held by Government entities, comprising 13% held by AAI on behalf of the Government of India, and 13% held by the Government of Telangana, while the remaining 74% is held by GMR Airports Limited (GAL).

GHIAL has referred to certain provisions of the Shareholders’ Agreement and submitted that the Board of GHIAL has decided to make payments to its shareholders towards services stated to be provided by them in relation to strategic leadership, governance and business sustainability. GHIAL has proposed that such consideration would be paid at the rate of 3% of standalone gross revenue, with effect from FY 2025-26, on a quarterly basis.

5.6.255. The Authority has analysed GHIAL’s submission and observes as under:

5.6.256. Clauses 3.4 and 3.5 of the Shareholders’ Agreement set out the roles of the Sponsors and the State Promoters in providing support to GHIAL. The activities listed for the State Promoters primarily relate to the initial support required for commencement of airport operations. The activities listed for the Sponsors also relate to commencement of airport operations and include reference to services to be provided in the ordinary course of business for operation, management and development of the airport and for provision of airport services.

5.6.257. The aforesaid clauses are general enabling provisions defining the broad roles and obligations of shareholders in relation to the airport project under the Concession Agreement framework. The Authority does not find any specific provision in the Shareholders’ Agreement which provides for payment of separate consideration to shareholders towards advice, consultation, strategic leadership, governance or business sustainability services.

5.6.258. The Authority is of the view that Hyderabad Airport was awarded to GAL through a transparent competitive bidding process with a clear mandate of development, construction, operation and maintenance of the airport for the concession period. Further, at the time of evaluation of the bids, GAL was shortlisted considering their ability to develop and manage the airport operations. Considering the Strategic, Management and Technical Service Fee to run the airport operations would defeat the above purpose and will lead to an additional fee being rendered to the shareholders in addition to the return on their invested equity.

5.6.259. The Authority further observes that GHIAL is a separate legal entity having its own senior management, personnel and functional structure for operating, managing and developing the airport. In addition, GHIAL already avails expert services from personnel of group companies and engages consultants/domain experts in various fields in the ordinary course of its business. Therefore, the Authority is of the view that a blanket quarterly payment to shareholders would lead to a risk of overlap between the proposed fees and costs already embedded in GHIAL’s existing expenditure base, including employee costs, administrative expenses, consultancy charges and other management-related expenses and may result in duplication of costs and consequential double recovery from airport users.

5.6.260. Accordingly, the Authority proposes not to consider the payment towards Strategic, Management, and Technical Service Fees to shareholders.

5.6.262. In view of the above, the Authority proposes to consider Aeronautical Operating Expenses of Rs. 3,090.14 Crores as per Table 135 for True up of the Third Control Period as against GHIAL’s submission of Rs. 3,277.23 Crores (as per Table 71).

5.6.263. The above variation is primarily attributable to non-consideration of Bad debts, Forex Fluctuations, Donation to Electoral Fund, CSR, Strategic, Management & Technical Service Fee and rationalization of expense heads such as Advertisement & Business promotions and Travelling & Conveyance allowance.

5.6.264. The Authority observed a substantial variation between the actual Operating Expenses incurred by the Airport Operator and the Operating Expenses approved by the Authority in the Tariff Order for the Third Control Period.

Upon examination, the Authority is of the view that the Airport Operator is expected to enhance operational efficiency through optimization of overall Operating Expenses, particularly employee costs and Operations &

Consultation Paper No: 02/2026-27 Page 133 of 308TRUE UP FOR THE THIRD CONTROL PERIOD Maintenance (O&M) expenses, including through leveraging technology and process improvements for cost rationalization.

5.6.265. The Authority further notes that any inefficient or avoidable expenditure arising from operational inefficiencies on the part of the Airport Operator ought not to be passed on to the airport users through tariffs. It is a well-recognized and consistently upheld regulatory principle that the inefficiency of one stakeholder cannot be transferred to, or borne by, another set of stakeholders. The Authority, therefore, considers it imperative that the Airport Operator undertakes appropriate measures to enhance operational efficiency and optimize such costs, so as to safeguard the interest of the passengers and prevent any avoidable financial burden being cast upon them.

GHIAL's Particulars Remarks No Submission GHIAL has classified Cargo Revenue as NAR in line with the TDSAT 1 Cargo Revenue 168.24 Order. The Authority, however, proposes to reclassify the same as Aeronautical Revenue.

2 Fuel 411.27 Same as above — proposed to be reclassified as Aeronautical Revenue Proposed to be reclassified as Aeronautical Revenue, consistent with 3 ICT & GH 311.04 the treatment adopted in the Third Control Period Tariff Order.

5.7.10 The Authority observes that the actual NAR for the Third Control Period has, on an aggregate basis, surpassed the projections considered in the Third Control Period Tariff Order. The line-item variance

analysis above demonstrates that the variance is primarily attributable to:

(i) Substantial Expansion of Commercial Footprint: The Authority observes that the commissioning of the 34 MPPA terminal expansion at Rajiv Gandhi International Airport, Hyderabad ("RGIA"), has enabled GHIAL to substantially augment its commercial footprint across multiple revenue streams,:

(a) Duty Free – expansion of the arrival store by 1,324 sq.m., addition of a last-minute departure store, and introduction of new lifestyle categories (perfumes, cosmetics, confectionery, etc.);

(b) Lounge – expansion of the operational area by 1,429 sq.m.; and

(c) Food & Beverage – expansion of the F&B operational area from 4,647 sq.m. to 8,767 sq.m., with the addition of new outlets.

(ii) Lounge concession – change of lounge operator, with the revenue share rising from 31% to 32%, accompanied by an increase in the Minimum Monthly Guarantee ("MMG") from ₹4 Million to ₹12 Million with effect from Q4 of FY 2022-23.

(iii) Post-Pandemic Traffic Recovery and Surge in International Footfall: The Authority observes that the post- pandemic recovery and subsequent acceleration of passenger traffic at RGIA — particularly international passenger footfall, which has registered a 3-year CAGR of 16.9%

(iv) Advertisement & Promotions – realisation of higher revenues on account of the post-pandemic recovery in advertising demand, coupled with aggressive advertising and brand-positioning strategies adopted by GHIAL; and

(v) Car Parking & Radio Taxi – higher net realisations on account of car parking operating at maximum efficiency.

Treatment of Revenue Streams

5.7.11 The Authority further notes that GHIAL has reclassified revenue from Cargo, Ground Handling and Fuel Farm services as Non-Aeronautical Revenue and has included the same in the computation of Non- Aeronautical Revenue for the purpose of true-up of the Third Control Period.

5.7.12 The Authority also notes that GHIAL has excluded other income, income from real estate and rentals from township from Non-Aeronautical Revenue for the purpose of True-up of the Third Control Period.

Consultation Paper No: 02/2026-27 Page 137 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.7.13 The Authority in line with the treatment adopted during Tariff determination of the Third Control Period

proposes the following treatment for the issues raised by GHIAL: • The Authority proposes to treat CGF services as aeronautical service and consequently the income from these services including cargo, ground handling and fuel farm including CSB and GPU as aeronautical revenue.

• The Authority proposes to treat income from ICT as aeronautical revenue. • The Authority in the Tariff Order for the Third Control has evaluated that township is housing both critical and non-critical employees. Critical employees are typically employed for handling aeronautical related services such as CISF, critical airport operations, airport fire safety services, security services etc. Hence the building blocks pertaining to Township are proposed to be treated based on critical staff ratio as aeronautical and remaining as non-aeronautical for purpose of tariff determination in this consultation Paper. This ratio is calculated every year based on actual occupancy and the Authority has decided to continue with the same treatment for the purpose of this Tariff Order. The Authority hence proposes to consider rental from township in the ratio of critical to non-critical staff (i.e. 85.7 % aero and 14.3% non-aero).

• The Authority, in the Tariff Order for the Third Control Period, has duly considered the submissions made by GHIAL with respect to the treatment of dividend income and interest income earned on investments, and is unable to accept the Operator's contention that revenue considered for the determination of the Aggregate Revenue Requirement (ARR) must invariably arise from assets forming part of the Regulatory Asset Base (RAB), the said contention being unsupported by any established regulatory principle. The Authority reiterates that, consistent with the classification adopted under the regulatory framework, the treatment of incidental income shall follow the classification of the underlying activity accordingly, cargo operations being classified as aeronautical, the income incidental thereto shall be treated as aeronautical, while duty-free operations being classified as non-aeronautical (as concurred with by GHIAL), the income incidental thereto shall be treated as non-aeronautical and reckoned for the purpose of computation of cross-subsidisation under the Shared Till framework. The Authority further proposes to treat Other Income and Income from Real Estate as non-aeronautical revenue.

• The Authority in the Tariff Order for the Third Control after giving due consideration to GHIAL's comments has decided to treat the fueling station on landside (city side) as common in the ratio of 50:50 (aeronautical: non-aeronautical) as this service is used by both airport users and other users as stated by GHIAL.

5.7.14 Based on the above treatment, the Non-Aeronautical Revenue proposed to be considered by the Authority for cross-subsidisation during the Third Control Period is shown in table below:

5.7.15 In view of the above, the Authority proposes to consider Non-Aeronautical Revenue of Rs. 3,482.87 Crores as per Table 140 for True up of the Third Control Period as against GHIAL’s submission of Rs. 3,520.43 Crores (as per Table 136) that includes Cargo, Ground Handling & Fuel Farm revenue as NAR.

5.7.16 In fact, the above variation is on account of: • CGF (Cargo, Ground Handling, Fuel Farm — including CSB and GPU) and ICT income excluded from Non Aeronautical Revenue and included in Aeronautical Revenue.

• Township rental income apportioned as 85.7% Aero : 14.3% Non-Aero, based on critical to non- critical staff ratio. • Consideration of Dividend & Interest income as Non-Aeronautical Revenue • ATC Rental income considered as Aeronautical Revenue.

• Real Estate Income treated as Non-Aeronautical revenue. • Landside Fueling Station treated as common (50:50), being availed by both airport and non-airport users.

5.8.6 The Authority, through its independent consultant, has verified the actual Aeronautical Revenues submitted by GHIAL for the true-up of the Third Control Period with reference to the audited financial statements and supporting information submitted by GHIAL.

5.8.7 The Authority notes that GHIAL while submitting the actual aeronautical revenues in Table 141 has not shown CGF revenues, CSB rentals under aeronautical revenue.

Consultation Paper No: 02/2026-27 Page 140 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.8.8 The Authority notes the submission of GHIAL that the Airports Authority of India (AAI) had disputed the license fee payments in respect of the CNS/ATM building at RGIA and had consequently stopped remitting the rentals with effect from April 2020. Pursuant to continuous follow-up by GHIAL, AAI has subsequently released the outstanding payments, and the said amount has been recognised as revenue in the FY26 financial statements of the Operator.

5.8.9 The Authority further notes that GHIAL, vide its letter No. GHIAL/AERA/2025-26/12131 dated

14.08.2025, requested the Authority to maintain the aeronautical tariffs for the fourth quarter of FY 2025- 26, i.e., January–March 2026, at the same level as applicable up to December 2025. GHIAL cited high capital expenditure requirements in the Fourth Control Period and carry-forward shortfall arising from accumulated under-recovery in the Third Control Period, inter alia due to higher transfer passenger traffic, as the basis for its request.

5.8.10 The Authority has analyzed the operators request through the Independent Consultant and notes that, on the basis of the information available in MYTP and subsequent clarifications thereon, even if the aeronautical tariff for the 4th Quarter of FY 2025-26 (January-March2026) is maintained at the same level as applicable till December,2025 there would be no likelihood of over recovery as there would actually be under recovery.

5.8.11 In view of the above, the Authority decided to maintain the Landing, Parking and UDF charges applicable from 01.04.2025 to 31.12.2025, as provided in Annexure I, for the last quarter of FY 2025-26, i.e., from

01.01.2026 to 31.03.2026.

5.8.12 The Authority proposes to consider CSB revenue as part of the aeronautical revenue, consistent with the decision undertaken during the tariff determination for the Third Control Period.

5.8.13 The Authority further notes the submission of GHIAL that the Cargo Satellite Building (CSB) was sold to GMR Hyderabad Aerotropolis Limited (GHAL) during FY 2023-24, pursuant to which the said asset has ceased to form part of GHIAL's asset base. Consequent upon the said transfer of ownership, the revenue from CSB has not been accounted for in GHIAL's books from FY25 onwards.

5.8.14 The Authority, through its independent consultant, sought details from GHIAL regarding revenue generated from Maintenance, Repair and Overhaul services. In response, GHIAL clarified that it does not earn any direct revenue from MRO activities, except for a 13% share of line maintenance revenue generated by the MRO service provider.

5.8.15 Based on the above examination, the revised Aeronautical Revenues proposed to be considered by the Authority for true-up of the Third Control Period is Rs. 5606.96 Crore, as shown in table below, as against GHIAL’s submission of Rs. 4685.74 crore.

5.9. True up of Aeronautical Taxes GHIAL’s Submission regarding True up of Aeronautical Taxes for the Third Control Period

5.9.1 GHIAL in its submission for true up for the Third Control Period as per MYTP for the Fourth Control Period has submitted the recalculated building block ‘T’ relating to Aeronautical Taxes. GHIAL has computed the earnings pertaining to regulated charges after considering aeronautical revenue, 30% of non- aeronautical revenue, operation and maintenance expenditure, concession fee, depreciation and interest expenses.

5.9.2 GHIAL has submitted that interest expenses have been computed as Approved RAB multiplied by approved / eligible debt gearing and approved cost of debt. GHIAL has further considered accumulated losses while computing the earnings on which normal tax is calculated. Accordingly, GHIAL has submitted that the taxes pertaining to regulated charges for the Third Control Period are Nil.

5.9.3 The Aeronautical Taxes submitted by GHIAL towards true up for the Third Control Period are shown in

5.9.4 As per the table above, GHIAL has submitted that there are no earnings on which normal tax is calculated during the Third Control Period after considering accumulated losses. Accordingly, GHIAL has submitted Aeronautical Taxes as Nil for the Third Control Period.

Recap of decisions taken by the Authority regarding Aeronautical Taxes for the Third Control Period

5.9.5 Decision No. 10.6.1: “To determine Aeronautical Taxes for the Third Control Period by allocating total taxes as per the aggregate Profit & Loss account between aeronautical and non-aeronautical components based on the ratio of taxes as per the aeronautical and non-aeronautical Profit & Loss accounts.”

5.9.6 The Aeronautical Taxes decided by the Authority for the Third Control Period are shown in the table below:

5.9.7 The Authority observes that GHIAL has considered 30% NAR in the estimation of aeronautical profit before tax (PBT), The fact that a part of NAR is used for cross-subsidization as per the hybrid till mechanism does not change nature of such revenue to aeronautical. Further, the cross subsidization as per the hybrid till mechanism is done to reduce tariff pressure on passenger and incentivize GHIAL to make effective investments in non-aeronautical income generating sources.

5.9.8 The Authority also notes that for the purpose of tax calculation, GHIAL has considered interest cost by applying notional gearing ratio. However, the Authority has considered actual aeronautical gearing for calculation of interest expenses.

Consultation Paper No: 02/2026-27 Page 143 of 308TRUE UP FOR THE THIRD CONTROL PERIOD

5.9.9 The Authority has relied upon the judgement of Hon'ble Supreme Court dated 11.07.2022 and worked out corporate tax based on regulatory accounts/regulatory building block. The Authority notes that Aeronautical Taxes are to be computed only on earnings pertaining to regulated charges after adjustment of accumulated losses. In case accumulated losses are available, the same are to be set off against the earnings pertaining to regulated charges before computing the tax liability.

5.9.10 GHIAL has computed the interest expenses considering that 48% of the average RAB is financed through debt. However, it is observed that, in actuality, 70% of the average RAB has been financed through debt.

Accordingly, the interest expenses have been reworked by considering debt financing at 70% of the average RAB.

5.9.11 Based on the above, the Authority proposes the Aeronautical Taxes for True Up for the Third Control

Period as shown in the table below:

6.1. GHIAL’s submission regarding Traffic projections for the Fourth Control Period

6.1.1 GHIAL has, in its MYTP for the Fourth Control Period, submitted traffic projections in respect of passenger traffic, Air Traffic Movements (ATM) and cargo for Rajiv Gandhi International Airport, Hyderabad ("RGIA") for the period FY 2026–27 to FY 2030–31. The said projections were developed by CAPA vide its traffic study dated 02.06.2025, which had projected total passenger traffic of 218.30 Mn, ATMs of 1,440.81 thousand and cargo of 1,319.30 thousand MT over the Fourth Control Period.

Passenger and ATM

6.1.2 CAPA has forecasted the passenger traffic movement for domestic and international flights at RGIA using a multi-faceted approach as set out hereunder: i. Demand-side forecasts have been developed on the basis of linear and exponential regression analyses undertaken at the national, state, and district levels;

ii. Supply-side forecasts have been formulated taking into account the prevailing fleet size and the operating characteristics of the airlines serving RGIA; iii. Industry-based assumptions, derived from prevailing analytical benchmarks, have been applied for the purpose of converting passenger forecasts into Air Traffic Movement ("ATM") forecasts;

iv. The aforesaid demand-side and supply-side analyses have been combined to arrive at the recommended primary forecast of passenger traffic and ATMs; and v. The said primary forecast has thereafter formed the basis for the derivation of secondary forecasts, including, inter alia, peak hour activity and transfer traffic.

Figure 1:Air Traffic Forecast Approach taken by CAPA

6.1.3 The transfer traffic projections in respect of Rajiv Gandhi International Airport, Hyderabad ("RGIA") for the Fourth Control Period have been developed separately for domestic and international transfers, and the

Consultation Paper No: 02/2026-27 Page 150 of 308TRAFFIC PROJECTIONS FOR THE FOURTH CONTROL PERIOD said projections have thereafter been aggregated to determine the total transfer passenger movements at the airport. The said exercise has been preceded by an examination of the historical distribution of transfer passengers across three principal segments, namely, Domestic-to-Domestic ("D-D"), Domestic-to- International / International-to-Domestic ("D-I/I-D"), and International-to-International ("I-I").

Cargo

6.1.4 For the purpose of forecasting cargo traffic at RGIA over the Fourth Control Period, CAPA has adopted the same regression-based econometric model used for passenger forecasting, duly supplemented with qualitative adjustments to account for the unique structural characteristics of cargo movements at RGIA.

6.1.5 CAPA in its report has submitted that, while the regression-based forecasting model linked to national, state, and catchment-area Gross Domestic Product ("GDP") provides a reasonable directional indicator of cargo volumes corresponding to the broader economic expansion, the said model does not, in itself, fully capture the commodity-specific drivers underlying the nature of cargo handled at RGIA, particularly with respect to international cargo.

6.1.6 CAPA has further submitted that, having regard to the commodity concentration of cargo at RGIA, it became necessary to factor in the dynamics of the pharmaceutical and Engineering & Aerospace industries while developing the cargo forecasts.

6.1.7 Based on the above methodology, CAPA has provided traffic forecasts for the Fourth Control Period. The growth rates considered for each traffic category, namely Passenger Traffic, ATM, and Cargo Traffic, are

presented in the table below:

Table 151: Growth Rates considered by CAPA towards Traffic Projections for GHIAL for the Fourth Control Period FY ending March 31 FY27 FY28 FY29 FY30 FY31 Passenger Traffic Domestic 11.56% 8.17% 9.97% 5.77% 7.01% International 12.10% 14.30% 13.90% 13.40% 10.80% ATM Domestic 11.20% 7.80% 8.90% 4.70% 5.50% International 11.90% 15.30% 12.40% 14.30% 9.60% Cargo Domestic 6.80% 6.80% 6.40% 6.30% 6.30% International 11.30% 11.50% 10.80% 10.80% 10.80%

6.1.8 Accordingly, GHIAL, in its MYTP, has submitted the traffic projections for the Fourth Control Period adopting the growth rates derived from the CAPA study, as detailed in the table below:

6.2. Authority’s examination regarding Traffic projections for the Fourth Control Period

6.2.1 The Authority has carefully examined the traffic projections submitted by GHIAL in respect of Rajiv Gandhi International Airport, Hyderabad ("RGIA") for the Fourth Control Period (i.e., FY 2026–27 to FY 2030–31), as developed by its independent traffic consultant, CAPA and undertaken a detailed examination of the methodology adopted.

Passenger Traffic and ATM

6.2.2 The Authority has examined the demand-side and supply side passenger forecasting methodology adopted by CAPA for Rajiv Gandhi International Airport, Hyderabad ("RGIA") for the Fourth Control Period, as submitted by GHIAL.

6.2.3 The Authority notes that the demand-side passenger forecasting methodology adopted by CAPA comprises an econometric regression-based three-tiered approach applied at the national, state, and district levels, supplemented by qualitative adjustments and validated through a back-testing exercise. The Authority is of the opinion that the said methodology is broadly consistent with established forecasting practices adopted

Consultation Paper No: 02/2026-27 Page 152 of 308TRAFFIC PROJECTIONS FOR THE FOURTH CONTROL PERIOD in past traffic forecasting exercises for major Indian airports and represents a methodologically sound framework for traffic projections.

6.2.4 The Authority further notes that the use of historical data spanning a period in excess of twenty (20) years lends robustness to the regression analysis. The three-tiered application of the model captures the layered economic drivers of demand at RGIA i.e. national-level inbound traffic, state-level economic activity in Telangana, and catchment-area economic activity.

6.2.5 The Authority notes that the methodology adopted by CAPA for the projection of transfer traffic comprises a segment-wise iterative approach, with separate treatment for the Domestic-to-Domestic ("D-D"), Domestic-to-International / International-to-Domestic ("D-I/I-D"), and International-to-International ("I- I") segments, and a combination of historical CAGR based extrapolation supplemented by qualitative adjustments. The Authority is of the view that the said segment-wise approach is broadly appropriate, having regard to the fact that each transfer segment is influenced by distinct demand drivers, competitive dynamics, and network considerations, and a uniform forecasting approach across all segments would not adequately capture the heterogeneity of transfer traffic at RGIA.

6.2.6 The ATM forecasting methodology adopted by CAPA, comprising hierarchical modelling at three levels and sequential four-step computation by aircraft type, is methodologically appropriate and consistent with established forecasting practices.

Cargo Demand

6.2.7 The Authority has carefully examined the cargo forecasting methodology adopted by CAPA for RGIA, comprising regression-based projections supplemented by commodity-specific qualitative adjustments, as submitted by GHIAL.

6.2.8 The Authority notes that CAPA has duly recognised the structural distinctiveness of cargo flows at RGIA being export-weighted and significantly concentrated in pharmaceutical and engineering commodities and has supplemented the regression-based forecasts with commodity-specific qualitative adjustments. The said approach is methodologically sound and represents a more granular treatment than a purely regression- based forecast, which would not adequately capture the commodity concentration at RGIA.

6.2.9 The Authority has also taken cognizance of the International Air Transport Association (IATA) report dated on the Air Passenger Market Analysis for the month of March 2026.

The key highlights of the IATA report are as follows: o The industry’s total Revenue Passenger-Kilometer (RPK) increased by 2.1% YoY in March, continuing to exceed historical records. Available Seat-Kilometer (ASK) fell by 1.7% YoY lagging demand growth.

o The Passenger Load Factor (PLF) improved by 3.1 percentage points compared to the previous year, reaching 83.6%, an all-time high for November. o Domestic traffic overall grew by 6.5% YoY. China led the main markets this month with a 13.7% rise in RPK. All monitored markets showed stable demand growth, although seat capacity in some areas plateaued.

o International passenger traffic for the industry declined marginally by 0.6% YoY in March.

Capacity on international routes fell by 6.2% YoY. With capacity contracting more than demand,

Consultation Paper No: 02/2026-27 Page 153 of 308TRAFFIC PROJECTIONS FOR THE FOURTH CONTROL PERIOD the international PLF rose by 4.7 percentage points to 84.1%, marking the highest March PLF on record for the international segment.

6.2.10 The Authority has further reviewed the historical traffic performance at Rajiv Gandhi International Airport, Hyderabad ("RGIA"), including the traffic growth rates witnessed over the preceding five financial years.

The Authority observes that passenger traffic at RGIA has registered a substantial recovery in the post- COVID-19 period, returning to pre-pandemic levels by FY 23. The said growth trajectory has been sustained thereafter, with passenger traffic having increased by 19.27% in FY 24 and 16.5% in FY 25 on a year-on-year basis, thereby reflecting a sustained momentum in air travel demand at the airport.

6.2.11 The Authority has examined the year-on-year growth rates considered by GHIAL for the purposes of its traffic projections, and notes that the actual passenger traffic at RGIA for FY 26 has fallen below the corresponding projection submitted by GHIAL. The said shortfall is attributable to certain global events and macroeconomic circumstances witnessed during the second half of the said financial year, which have moderated the pace of traffic growth.

6.2.12 In view of the above, the Authority (through its independent consultant) sought clarification from GHIAL on the rational for considering high growth rates in the traffic projection.

6.2.13 In response, GHIAL submitted revised forecasted passenger traffic for the Fourth Control Period, as

detailed below:

Table 153: Revised forecasted passenger traffic submitted by GHIAL for the Fourth Control Period Particulars FY27 FY28 FY29 FY30 FY31 Total Passenger Traffic (Mn) Domestic 28.7 32.1 36.4 38.6 41.2 177.0 Growth % 11.2% 11.8% 13.4% 6.0% 6.7% International 6.3 7.2 8.2 9.3 10.3 41.3 Growth % 10.5% 14.3% 13.9% 13.4% 10.8% Total 35 39.3 44.6 47.9 51.5 218.3 Growth % 11.1% 12.3% 13.5% 7.4% 7.5% Air Traffic Movements (Nos) Domestic 198,296 221,115 248,379 260,042 274,391 1,202,223 Growth % 12.2% 11.5% 12.3% 4.7% 5.5% International 36,419 41,978 47,168 53,919 59,110 238,594 Growth % 13.6% 15.3% 12.4% 14.3% 9.6% Total 234,715 263,093 295,547 313,961 333,501 1,440,817 Growth % 12.4% 12.1% 12.3% 6.2% 6.2%

6.2.14 The Authority has observed that comparatively higher year-on-year growth rates have been considered by GHIAL for the first three years of the Fourth Control Period in respect of the projected passenger traffic at Rajiv Gandhi International Airport, Hyderabad ("RGIA"). Accordingly, the Authority sought further clarification from GHIAL with regard to the basis and underlying assumptions for the said growth rates

6.2.15 The Authority has examined GHIAL's response in this regard, as furnished vide its e-mail dated 18.02.2026 and notes that the said comparatively higher growth rates have been projected having regard to the following

factors:

Consultation Paper No: 02/2026-27 Page 154 of 308TRAFFIC PROJECTIONS FOR THE FOURTH CONTROL PERIOD I. The expected normalisation of IndiGo's operations by the Summer 2026 schedule, based on the airline schedules filed by the said carrier;

II. The induction of new aircraft by Indian carriers towards the end of Q2 of FY 28 or the commencement of Q3 of FY 28; and III. The aggressive international network expansion plans of Indian carriers, including, inter alia, the

following: • IndiGo's announcement that 40% of its total operations shall be international by the year 2030; • Akasa Air's preparation for a phased international expansion; and • Air India's major international network expansion as part of its multi-year transformation under the Tata Group.

6.2.16 The Authority has examined the historical trajectory of passenger traffic at Rajiv Gandhi International Airport, Hyderabad ("RGIA"), with reference to the CAGR observed over various time horizons, viz., 10- year (FY 2015-16 to FY 2025-26) and 3-year (FY 2022-23 to FY 2025-26).

6.2.17 The Authority observes that the 3-year CAGR (FY 2022-23 to FY 2025-26), being the most recent and steady-state period in the post-pandemic recovery phase, provides a credible and forward-looking empirical basis for assessing the underlying growth momentum of passenger traffic at RGIA, free from the distortions of the pandemic-impacted base years that influence the longer-term CAGR.

6.2.18 The Authority observes the following key trends emerging from the said analysis:

(i) Robust Total Passenger Growth: The total passenger traffic at RGIA has registered a 3-year CAGR of 13.2%, which is materially higher than the 10-year CAGR of 9.3%, indicating a structural acceleration in the growth momentum of the Airport in the post-pandemic period. The said growth rate is reflective of the enhanced connectivity, expanded route network, and the strategic positioning of Hyderabad as a key aviation hub in southern India.

(ii) Strong International Traffic Growth: International passenger traffic has witnessed a 3-year CAGR of 16.9%, materially outpacing the 10-year

6.2.19 The Authority notes that the growth rates submitted by GHIAL for the projection of Passenger Traffic and ATMs over the Fourth Control Period have been applied to the projected base figure for FY26. With the actual traffic data for FY 26 now being available, the Authority is of the considered view that the actual figures for FY26, being more recent and empirically verifiable, ought to constitute the appropriate base for projecting traffic over the Fourth Control Period. The Authority, accordingly, proposes to determine the said growth rates to the actual FY26 base, in lieu of the projected base.

6.2.20 Based on the foregoing, the projected Passenger Traffic (Total and Billable), ATM and Cargo Traffic

proposed to be considered by the Authority for the Fourth Control Period is presented in the table below:

6.3. Authority’s proposal regarding Traffic projections for the Fourth Control Period Based on the material before it and its examination, the Authority proposes the following with respect to

Traffic projections for the Fourth Control Period:

6.3.1 To consider Traffic projections as per Table 154 for the Fourth Control Period.

6.3.2 To true up the traffic volume (Passenger, ATM and cargo) on the basis of actual traffic in the Fourth Control Period while determining tariff for the Fifth Control Period.

Consultation Paper No: 02/2026-27 Page 157 of 308CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE FOURTH CONTROL PERIOD 7 CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE

(RAB) FOR THE FOURTH CONTROL PERIOD

7.1. Background

7.1.1 Regulatory Asset Base (RAB) is one of the essential elements in the process of tariff determination. The return to be provided on the RAB constitutes a considerable portion of the Aggregate Revenue Requirement for an Airport Operator. To encourage the participation of the private sector in airport development and operations, investors must be fairly compensated for the capital investment made. At the same time, to safeguard the interests of the airport users, it must be ensured that the aeronautical capital additions are necessary, reasonable and justified.

7.1.2 GMR Hyderabad International Airport Limited (“GHIAL”) has submitted its MYTP for the Fourth Control Period in respect of Rajiv Gandhi International Airport, Hyderabad. As part of the MYTP, GHIAL has submitted its capital expenditure plan for the Fourth Control Period along with details of project-wise capital expenditure, means of finance, proposed capitalisation, and classification of assets into aeronautical, non-aeronautical, common and non-airport categories.

7.1.3 The capital expenditure plan submitted by GHIAL for the Fourth Control Period is primarily aimed at augmentation of airport capacity, strengthening of airside and landside infrastructure, development of terminal and associated facilities, and undertaking of other capital works required to cater to the projected traffic growth, operational requirements and service quality standards during the Fourth Control Period.

7.1.4 The Authority notes that RGIA has witnessed sustained traffic growth over the previous control periods and GHIAL has undertaken significant expansion in the Third Control Period to augment the airport capacity to 34 MPPA. In its MYTP for the Fourth Control Period, GHIAL has submitted a further capital expenditure plan to cater to the projected traffic growth and to create the required airport infrastructure over the next control period.

7.1.5 The Authority further notes that the capital expenditure submitted by GHIAL for the Fourth Control Period comprises various project heads including terminal-related development, airside infrastructure, landside infrastructure, support systems, utilities, and other allied works. GHIAL has also submitted the proposed year-wise capitalisation schedule and the allocation of such assets between aeronautical and non- aeronautical activities.

7.1.6 GHIAL has submitted that RGIA continues to be one of the major airports in India in terms of passengers, Air Traffic Movements (“ATMs”) and cargo handled. As per GHIAL’s submission, in FY 2024-25, RGIA handled about 7.1% of the total passengers and 7.0% of the total ATMs handled across all airports in India, thereby placing RGIA at the fourth position among Indian airports in terms of total passengers and ATMs handled, after Delhi, Mumbai and Bengaluru airports. GHIAL has further submitted that RGIA handled 1,82,426 metric tonnes of cargo in FY 2024-25, placing it amongst the top five airports in India in terms of cargo handled.

7.1.7 GHIAL has submitted that in FY 2024-25, RGIA handled 29.16 million passengers, including 24.43 million domestic passengers and 4.73 million international passengers. GHIAL has further submitted that RGIA was connected to 72 domestic destinations and 24 international destinations in FY 2024-25. While RGIA

Consultation Paper No: 02/2026-27 Page 158 of 308CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE FOURTH CONTROL PERIOD was the fourth busiest airport overall in terms of passenger traffic, GHIAL has stated that the airport recorded a faster domestic passenger growth rate compared to certain larger airports and was the sixth busiest airport in terms of international passengers, with one of the highest growth rates in international passenger traffic over the period FY 2014-15 to FY 2024-25.

7.1.8 GHIAL has submitted that between FY 2014-15 and FY 2024-25, RGIA’s compound annual growth rate (“CAGR”) significantly outpaced the national average across all major categories. As per GHIAL, RGIA recorded CAGR of 10.9% in total passenger traffic against the all-India average of 8.0%, CAGR of 5.4% in freight against the all-India average of 3.9%, and CAGR of 8.0% in aircraft movements against the all- India average of 6.1%, despite the impact of COVID-19. GHIAL has further submitted that amongst major airports, RGIA recorded the highest CAGR for domestic passenger traffic movements.

7.1.9 GHIAL has submitted that based on its internal assessment, the current capacity of the Southern Precinct can be enhanced to handle up to 47 MPPA through certain modifications to operational processes and infrastructure, including terminal, airside and landside infrastructure. GHIAL has stated that this approach involves maximising utilisation of existing assets through marginal capital expenditure before undertaking extensive new infrastructure development. As per GHIAL, by optimising processes and undertaking strategic enhancements to the current infrastructure, the Southern Precinct can accommodate higher traffic volumes without immediate requirement for large-scale new construction. GHIAL has categorised such works as capacity enhancement works for the Southern Precinct.

7.1.10 With respect to development of the Northern Precinct, GHIAL has submitted that initiation of the same is necessary considering both airside and terminal-side capacity constraints expected during the Fourth Control Period. GHIAL has stated that while the current Passenger Terminal Building is designed to process 34 MPPA, the runway currently has 42 approved movements per hour and is handling an average of around 36 peak hour movements. GHIAL has submitted that with high-intensity operations, subject to requisite approvals, the airside capacity may be enhanced to 46 ATMs per hour. However, as per the traffic study undertaken by CAPA, demand for 46 ATMs per hour is expected to be exceeded during FY 2028-29.

(E) General Capex

Consultation Paper No: 02/2026-27 Page 166 of 308CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE FOURTH CONTROL PERIOD

7.3.2. While examining the capital expenditure proposed by GHIAL for the Fourth Control Period, the Authority has taken into consideration the traffic projections submitted by GHIAL, the capacity available at the existing Southern Precinct, the revised capacity assessment of the existing terminal building, and the requirement for development of additional airport infrastructure over the Fourth Control Period.

7.3.3. The Authority notes that GHIAL had initially submitted that the existing airport infrastructure, even after the capacity augmentation undertaken during the Third Control Period, would require further enhancement to cater to the projected traffic growth at RGIA. GHIAL had proposed that the enhancement of the Southern Precinct would increase the terminal capacity from 34 MPPA to 47 MPPA, and that the proposed development of the Northern Precinct would add another 20 MPPA, thereby increasing the total terminal capacity to 67 MPPA.

7.3.4. Subsequently, GHIAL, based on Jacob’s study on “Terminal 1 Capacity Assessment”, bearing Report No.

GHIAL-JAC-P-MPL-V-PDR-004 dated 28.02.2026, has made a revised submission that the Terminal 1 can maintain stable operational performance up to approximately 37 MPPA (pending implementation of long-term terminal development initiatives) which through peak spreading and process improvements can achieve a maximum capacity of 40 MPPA.

7.3.5. The Authority notes GHIAL’s submission that the Jacob’s study assessment is based on all key passenger processing systems considering existing infrastructure, BCAS requirement and operational parameters currently in use at the airport. The Authority further notes from the submission of GHIAL that Terminal 1 is approaching its practical operating limits, with domestic capacity primarily constrained by baggage reclaim facilities and international capacity limited by check-in processing. The Authority further notes that baggage make-up positions and kerbside operations have also been identified as critical pressure points.

7.3.6. The Authority notes that the targeted operational and infrastructure interventions proposed by GHIAL, including upgrades to the BHS/BMA systems, reconfiguration of check-in facilities, expansion of domestic security screening capacity, enhancement of baggage reclaim flexibility, conversion from Self Bag Drops to Assisted Bag Drops, conversion of swing PESCs, addition of one machine in the PESC area for domestic- to-domestic transfer, and other miscellaneous works, are expected to improve the operational performance of Terminal 1 up to 37 MPPA. Any incremental increase in annual traffic beyond 37 MPPA and up to 40 MPPA would be achievable primarily through effective spreading of peak traffic.

7.3.7. Accordingly, the Authority proposes to consider 40 MPPA as the capacity that can be achieved through the proposed Southern Precinct enhancement. However, the Authority further expects GHIAL to maintain the required service standards at the airport after carrying out the aforesaid modification/upgradation at Terminal 1.

Capex Evaluation through an Independent Capex Consultant

Soft Costs

7.3.73. For soft cost components, M/s RITES Limited has considered the rates broadly in line with the approach adopted for finalisation of capex for the Third Control Period. The soft cost components comprise preliminaries and other costs, permits and insurance, design and PMC, and contingencies.

7.3.74. The Authority, upon review of GHIAL’s submission, explanations and relevant supporting documents, has

the following views with respect to the soft cost proposed by GHIAL for the Fourth Control Period: • The Authority notes that GHIAL has proposed soft cost at 14% of the project cost. The Authority observes that in the case of other PPP airports such as BIAL, DIAL, etc., similar costs such as Preliminaries, Design, Project Management Consultancy, Insurance, Permits and other related soft costs have generally been considered in the range of 8% to 11% of the project cost. Accordingly, the Authority is of the view that the soft cost of 14% claimed by GHIAL is on the higher side and requires moderation.

• The Authority also notes that certain capex items proposed by GHIAL relate to airside and operational works, including pavement works, stand conversion and other infrastructure augmentation. For such works, PMC and related soft cost requirements are generally lower and are normally observed to be in the range of 1% to 3%, depending upon the nature and complexity of the work.

• The Authority further observes that GHIAL has proposed soft cost on an overall basis across capex items, including works such as procurement of equipment, IT systems, security systems, vehicles, plant and machinery, and other bought-out / SITC items. The Authority is of the view that applying a uniform soft cost percentage on all such items may result in overstatement of the eligible cost, particularly where the scope already includes installation, commissioning and vendor-related support.

7.3.75. Accordingly, considering the nature of the capex proposed by GHIAL, the mix of civil works, bought-out items and SITC contracts, the benchmark observed in other PPP airports, and the need to avoid loading of excessive soft costs on all capex items, the Authority proposes to restrict the allowable soft cost to 10% of

Consultation Paper No: 02/2026-27 Page 183 of 308CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE FOURTH CONTROL PERIOD the aeronautical capex of the projects allowed by the Authority for the Fourth Control Period, as against 14% claimed by GHIAL. The amount towards soft cost shall accordingly be computed on the aeronautical portion of the capex approved by the Authority and considered for inclusion in the Regulatory Asset Base, subject to actual capitalization, reconciliation with audited financial statements / Fixed Asset Register and prudence check.

Table 191: Soft Costs assessed by M/s RITES Limited for Northern Runway and Associated Airside Works (Rs. In crores) Particulars Amount Hard Costs 3705.28 Soft Costs (10%) 370.53

7.3.76. Based on the above analysis, the Authority proposes to consider Rs. 4,075.81 Crores towards Northern Runway and associated airside works for the Fourth Control Period. The item-wise cost proposed to be

considered by the Authority is shown below:

(C) Northern Precinct development – Landside Works Figure 5: Conceptual View of the Proposed Northern Passenger Terminal Building (NPTB) — 2,25,000 sqm C1. Terminal Building

7.3.78. The Authority has examined GHIAL’s proposal for development of the New Northern Passenger Terminal Building of 2,25,000 sqm with a design capacity of 20 MPPA, along with capacity enhancement works at the existing Southern Terminal. The Authority notes that the Southern Terminal capacity enhancement is proposed to be achieved through targeted operational and infrastructure interventions such as BHS/BMA upgrades, check-in reconfiguration, expansion of domestic security screening areas and baggage reclaim improvements, without any material addition to the existing terminal floor area. With these interventions, the Southern Terminal capacity is expected to increase from 34 MPPA to 40 MPPA, and together with the proposed NPTB, the combined terminal capacity at RGIA is expected to increase to around 60 MPPA.

7.3.79. The Authority has assessed the proposed terminal sizing with reference to projected traffic growth, peak- hour passenger demand, IMG/IATA planning norms and comparable airport benchmarks. For the purpose of assessment, the Authority has considered a Peak Hour Passenger (“PHP”) factor of 0.03% for the combined terminal system, which results in a combined PHP of 18,000 passengers for 60 MPPA capacity.

The Authority notes that the combined terminal area of 6,04,370 sqm results in an area provision of around

33.58 sqm/PHP, which is within reasonable bounds when compared with applicable planning norms and benchmarks for integrated terminals.

7.3.80. The Authority further notes that both the existing Southern Terminal and the proposed NPTB are integrated terminals handling domestic and international traffic with swing capability. Accordingly, integrated terminal norms are relevant for assessing the reasonableness of terminal area. The area per PHP norms

considered by the Authority are set out below:

Table 194: Area per PHP Norms considered for Terminal Planning Standard Domestic Terminal International Terminal Integrated Terminal IMG 20 sqm/PHP 27.5 sqm/PHP 25 sqm/PHP IATA 25 sqm/PHP 35 sqm/PHP ~30 sqm/PHP

7.3.81. The Authority notes that M/s RITES Limited has examined the proposed NPTB area of 2,25,000 sqm.

RITES has assessed the NPTB using the IATA ADRM peak-hour factor of 0.035%, resulting in PHP of 7,000 passengers and area provision of 32.14 sqm/PHP. M/s RITES Limited has observed that the proposed NPTB area is in line with applicable norms and comparable airport benchmarks and has not recommended any reduction in the proposed area. The Authority also notes that the Southern Terminal enhancement works have been reviewed by RITES and no reduction in the proposed scope has been recommended.

Table 195: Summary of Area Considered for Hyderabad Terminals Particulars Value Combined Terminal Capacity in Fourth Control Period 60 MPPA Combined PHP at 0.03% 18,000 Existing Southern Terminal area unchanged 3,79,370 sqm Proposed NPTB Phase 1 area 2,25,000 sqm Combined Terminal area 6,04,370 sqm Combined Area per PHP 33.58 sqm/PHP RITES-assessed NPTB Area per PHP at 0.035% 32.14 sqm/PHP

7.3.82. Accordingly, based on the assessment of PHP, terminal area norms, comparable airport benchmarks and the findings of RITES, the Authority proposes to consider the NPTB area of 2,25,000 sqm for 20 MPPA capacity as proposed by GHIAL for the purpose of cost assessment.

7.3.83. For the proposed Northern Passenger Terminal Building, M/s RITES Limited has considered the approved rate of terminal building works determined during the Second Control Period and escalated the same using WPI-based inflation up to the expected year of capitalisation. The Authority notes that the proposed Northern Passenger Terminal Building is planned with an area of 2,25,000 sqm and is intended to provide additional passenger handling capacity in the Northern Precinct.

M/s RITES Limited has considered a unit rate of Rs. 78,898.73 per sqm and an area of 15,750 sqm, based on which the cost works out to Rs. 124.27 Crores. Since the cost proposed under this item is lower than the cost assessed by M/s RITES Limited, the Authority proposes to consider Rs. 81.00 Crores towards underpass extension along east-west road.

D7. North-South Road

7.3.110. For the North-South Road, M/s RITES Limited has assessed the cost based on CPWD DSR rates. M/s RITES Limited has considered a rate of Rs. 1,81,56,151.58 per km and a quantity of 21 km, based on which the cost works out to Rs. 38.13 Crores. Accordingly, the Authority proposes to consider Rs. 38.13 Crores towards North-South Road as against Rs. 44 Crores submitted by GHIAL.

7.3.111. For the 18m Road (2+2), M/s RITES Limited has assessed the cost based on CPWD DSR rates. M/s RITES Limited has considered a rate of Rs. 1,81,56,151.58 per lane-km and a quantity of 12.40 km, based on which the cost works out to Rs. 22.51 Crores. Since the cost proposed under this item is lower than the cost assessed by M/s RITES Limited, the Authority proposes to consider Rs. 15.00 Crores towards 18m Road (2+2).

Figure 9: Proposed Alignment of 18m Wide Road (2+2 Lanes) along the South-East Side Connecting East- West Road and Golf Course Road Soft Costs

7.3.112. For the soft cost components, M/s RITES Limited has considered the rates broadly in line with the approach adopted for capex assessment, comprising preliminaries and other costs, permits and insurance, design and PMC, and contingencies. The soft costs have been considered as a percentage of the hard costs.

7.3.113. The Authority, upon review of GHIAL’s submission, explanations and relevant supporting documents, has

the following views with respect to the soft cost proposed by GHIAL for the Fourth Control Period: • The Authority notes that GHIAL has proposed soft cost at 14% of the project cost. The Authority observes that in the case of other PPP airports such as BIAL, DIAL, etc., similar costs such as Preliminaries, Design, Project Management Consultancy, Insurance, Permits and other related soft costs have generally been considered in the range of 8% to 11% of the project cost. Accordingly, the Authority is of the view that the soft cost of 14% claimed by GHIAL is on the higher side and requires moderation.

• The Authority also notes that certain capex items proposed by GHIAL relate to airside and operational works, including pavement works, stand conversion and other infrastructure augmentation. For such

Consultation Paper No: 02/2026-27 Page 193 of 308CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE FOURTH CONTROL PERIOD works, PMC and related soft cost requirements are generally lower and are normally observed to be in the range of 1% to 3%, depending upon the nature and complexity of the work.

• The Authority further observes that GHIAL has proposed soft cost on an overall basis across capex items, including works such as procurement of equipment, IT systems, security systems, vehicles, plant and machinery, and other bought-out / SITC items. The Authority is of the view that applying a uniform soft cost percentage on all such items may result in overstatement of the eligible cost, particularly where the scope already includes installation, commissioning and vendor-related support.

7.3.114. Accordingly, considering the nature of the capex proposed by GHIAL, the mix of civil works, bought-out items and SITC contracts, the benchmark observed in other PPP airports, and the need to avoid loading of excessive soft costs on all capex items, the Authority proposes to restrict the allowable soft cost to 10% of the aeronautical capex of the projects allowed by the Authority for the Fourth Control Period, as against 14% claimed by GHIAL. The amount towards soft cost shall accordingly be computed on the aeronautical portion of the capex approved by the Authority and considered for inclusion in the Regulatory Asset Base, subject to actual capitalization, reconciliation with audited financial statements / Fixed Asset Register and prudence check.

Table 204: Soft Costs assessed by M/s RITES Limited for Airport Connectivity and Transport Systems (Rs. In crores) Particulars Amount Sub-total: Hard Cost 859.95 Soft Costs 86.00

7.3.115. Accordingly, the Authority proposes to consider Rs. 945.95 Crores towards Airport Connectivity and Transport Systems for the Fourth Control Period, subject to actual capitalisation and asset allocation at the time of true-up. The item-wise cost proposed to be considered by the Authority is shown below:

(E) General Capex

7.3.116. The Authority notes that GHIAL has proposed a total General Capital Expenditure of Rs. 1,302.3 Crores for the Fourth Control Period. The proposed capex is spread across various departments to support airport

Consultation Paper No: 02/2026-27 Page 194 of 308CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE FOURTH CONTROL PERIOD operations, infrastructure augmentation, maintenance requirements, security, and technology-related initiatives.

7.3.117. The Authority observes that the major allocations proposed by GHIAL include Rs. 391.8 Crores towards Security and Vigilance, Rs. 389.5 Crores towards Project, Engineering & Maintenance, Rs. 197.0 Crores towards IT infrastructure, and Rs. 131.5 Crores towards Strategic Initiatives. Further, GHIAL has proposed Rs. 94.8 Crores towards Terminal Operations, Rs. 53.4 Crores towards Landscape Development, and Rs.

44.2 Crores towards Airport Rescue and Fire Fighting.

7.3.118. The Authority notes that GHIAL has proposed total General Maintenance CAPEX of Rs. 1,302 Crores for the Fourth Control Period. The Authority further notes that the General Maintenance CAPEX approved by AERA, vide Tariff Order for the Third Control Period, was Rs. 1,527.74 Crores.

7.3.119. Since the General Maintenance Capex proposed by GHIAL for the Fourth Control Period is broadly in line with, and lower than, the General Maintenance Capex approved for the Third Control Period, the Authority finds the same to be reasonable. Accordingly, the Authority proposes to consider General Maintenance Capex of Rs. 1,302 Crores for the Fourth Control Period.

Table 206: General Capex proposed to be considered for the Fourth Control Period (Rs. In crores) Particulars FY 27 FY 28 FY 29 FY 30 FY 31 Total General Maintenance Capital Expenditure 552.91 268.01 142.42 175.11 163.81 1302.26

(F) Capital Expenditure deferred from Third Control Period to Fourth Control Period

7.3.120. The Authority notes that capital expenditure amounting to Rs. 168.50 Crores, comprising assets which remained under CWIP and carry-forward items as on 31.03.2026, was not considered for capitalization during the Third Control Period, since the same had not been capitalized / put to use during FY 2026.

7.3.121. GHIAL has submitted that the said deferred capital expenditure is proposed to be capitalized in FY 2027, i.e., during the Fourth Control Period. The Authority notes that the deferred amount primarily relates to residual works of the expansion project, including terminal expansion, apron and taxiway works, road infrastructure, ICT cost, enabling works and related soft costs, which form part of the overall expansion capital expenditure.

7.3.122. The Authority is of the view that since the amount of Rs. 168.50 Crores was deferred from the Third Control Period only on account of non-capitalization as on 31.03.2026, and not on account of prudence disallowance, the same may be considered in the Fourth Control Period upon actual capitalization by GHIAL.

7.3.123. Accordingly, the Authority proposes to allow the deferred capex of Rs. 168.50 Crores (from Third Control Period) in the Fourth Control Period, subject to GHIAL capitalizing the assets in FY 2027, submission of requisite supporting documents, and reconciliation with the audited financial statements / fixed asset register.

Interest During Construction

7.3.124. The Authority has examined the IDC submitted by GHIAL for the capital projects proposed during the Fourth Control Period. GHIAL has submitted the IDC computation based on the proposed debt drawdown, utilisation of debt for eligible capital expenditure, assumed cost of debt and the capitalisation schedule of

Consultation Paper No: 02/2026-27 Page 195 of 308CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE FOURTH CONTROL PERIOD the projects. The Authority notes that GHIAL has considered interest cost at 10.00% on the average debt utilised for the project during the construction period.

7.3.125. The Authority has examined the methodology adopted by GHIAL for computation of IDC and finds the same to be reasonable. However, since the Authority has proposed certain adjustments to the capital cost based on the examination of project scope, quantities, applicable benchmarks and reasonableness of costs, the IDC has also been recomputed on a proportionate basis corresponding to the capital cost proposed to be considered by the Authority. Accordingly, IDC has been allowed only to the extent attributable to the eligible capital cost proposed to be considered for the Fourth Control Period.

7.3.136. The Authority proposes to reduce 1% of the uncapitalized project cost from the ARR / target revenue as re-adjustment in case any particular capital project is not completed/ capitalized as per the approved capitalization schedule. It is further proposed that if the delay in completion of the project is beyond the timeline given in the capitalization schedule, due to any reason beyond the control of GHIAL or its contracting agency and is properly justified, the same would be considered by the Authority while truing up the actual cost at the time of determination of tariff for the next Control Period. The re-adjustment in the ARR/ Target Revenue is to protect the interest of the stakeholders who are paying for services provided by GHIAL and is also encouragement for GHIAL to commission/ capitalize the proposed assets as per the approved CAPEX plan/schedule.

961.50 Crores has been classified as aeronautical, Rs. 69.60 Crores as non-aeronautical, Rs. 213.07 Crores as common and Rs. 58.10 Crores as non-aeronautical CGF.

7.3.144. Based on the above, GHIAL has submitted total General Capex of Rs. 1,302.26 Crores for the Fourth Control Period, of which Rs. 961.50 Crores has been classified as aeronautical capex. The common capex has been separately identified by GHIAL for allocation between aeronautical and non-aeronautical components.

Authority’s examination regarding Asset Allocation for the Fourth Control Period

7.3.145. The Authority has examined the classification of total capital expenditure proposed by GHIAL for the Fourth Control Period into aeronautical and non-aeronautical components. The Authority notes that GHIAL has classified certain assets differently from the asset classification principles adopted by AERA for regulatory tariff determination. Accordingly, the Authority has reclassified such assets in line with the AERA principles. Further, the soft costs have been apportioned in line with the aeronautical proportion of the underlying hard costs. The Authority has computed the aeronautical capex separately for each of the capital expenditure heads proposed for the Fourth Control Period.

7.3.146. For the purpose of determination of RAB, the Authority proposed to apportion the common assets related to passenger terminal into Aero and Non-Aero assets utilising the Terminal Area Ratio of

84.6% (Aero) and 15.4% (Non Aero). Whereas, the common assets pertaining to functions other than the terminal building are proposed to be apportioned utilising the average Gross Fixed Asset ratio for the Third Control Period i.e. 89.56% (Aero) and 10.44% (Non Aero).

7.3.147. The project-wise analysis of asset allocation, along with the rationale for changes in classification proposed by the Authority, is provided below:

7.3.148. The rationale for the reclassification of asset allocation proposed by the Authority is set out below: • Improvement of Departure & Arrival Entry & Exit NAKA: The assets shall jointly be used by all terminal visitors like passengers, visitors and the staff of airport & airport concessionaires. Hence, the Authority proposes to classify the same as common, to be allocated in the ratio of Terminal Area Ratio.

• Other Miscellaneous: The exact nature and usage of the assets under this head have not been separately identified. Since such assets may be used jointly by passengers, visitors and staff of airport & airport concessionaires, the Authority proposes to classify the same as common, to be allocated in the ratio of Terminal Area Ratio.

7.3.149. The rationale for the reclassification of asset allocation proposed by the Authority is set out below: • External Utilities: External infrastructure such as DG sets, UPS, substations, power distribution boards, LT switchboards and HT cables serve both aeronautical and common airport assets. Accordingly, these assets are required to be bifurcated based on their usage for appropriate allocation.

• GSE Building: Assets pertaining to ground handling are to be considered Aero. • GSE Parking: Assets pertaining to Ground handling are to be considered Aero.

7.3.150. The rationale for the reclassification of asset allocation proposed by the Authority is set out below: • Landside Ancillary Buildings, Landscaping and Landside Roads: The Authority notes that landside connectivity infrastructure is used by aeronautical passengers, users of non-aeronautical commercial facilities, airport employees and the general public. Accordingly, the Authority proposes to classify such assets as common assets.

• External Utilities: External infrastructure such as DG sets, UPS, substations, power distribution boards, LT switchboards and HT cables serve both aeronautical and common airport assets. Accordingly, these assets are required to be bifurcated based on their usage for appropriate allocation.

7.3.151. The Authority notes that the assets are expected to be used jointly by passengers, visitors, airport staff and staff of airport concessionaires. Accordingly, the Authority proposes to classify the same as common assets, to be allocated between aeronautical and non-aeronautical components in the Terminal Area Ratio.

7.3.152. The elements forming part of General Capex have also been examined from the perspective of their nature, end-use and beneficiary profile. The Authority observed that certain assets proposed under General Capex are not exclusively used for aeronautical activities and are expected to serve multiple user groups, including passengers, visitors, airport employees, concessionaires and users of non-aeronautical commercial facilities. Accordingly, such assets have been reclassified, wherever required, based on the

Consultation Paper No: 02/2026-27 Page 205 of 308CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE FOURTH CONTROL PERIOD above observations and in line with the asset allocation principles adopted by AERA for regulatory tariff determination.

7.3.153. Further, for the capital expenditure deferred from the Third Control Period to the Fourth Control Period, the Authority has considered the aeronautical allocation in the same proportion as proposed to be considered during the Third Control Period. The Authority notes that these items were originally part of the capital expenditure proposed for the Third Control Period and their asset classification and aeronautical allocation had already been examined in the context of the Third Control Period tariff determination.

7.3.154. Accordingly, the project-wise aeronautical allocation of capex proposed to be considered by the Authority

is provided in the tables below:

GHIAL has considered the weighted average rate of depreciation at 5.65% for computing depreciation on the assets proposed to be capitalised during the Fourth Control Period.

7.5.2. The Authority has examined the depreciation computation submitted by GHIAL with reference to the Fixed Asset Register and the actual asset class-wise data submitted by GHIAL. Based on such examination, the Authority has recomputed the weighted average rate of depreciation, which works out to 5.75%. The Authority notes that the useful life considered by GHIAL for various asset classes is broadly in line with the useful life considered by the Authority. The asset class-wise useful life considered by GHIAL and proposed to be

considered by the Authority is shown in the table below:

8.2.2. The Authority proposes to continue to adopt the Cost of Equity of 15.17% for the Fourth Control Period.

The Authority also proposes to continue with the notional debt-equity ratio of 48%:52% as considered for the Third Control Period.

Cost of Debt

8.2.3. The Authority notes the submission made by GHIAL with regards to Cost of Debt. GHIAL has projected the Cost of Debt based on the outflows of the existing loans as on March 31, 2025 at the original drawdown foreign currency rate. GHIAL has also considered additional debt proposed to be raised for capital projects including construction of Northern Precinct and airport connectivity projects during the Fourth Control Period.

8.2.4. The Authority notes that GHIAL has proposed to raise additional debt of Rs. 9,872 Crores for the capital projects during the Fourth Control Period at an interest rate of 10% p.a. for a tenure of 10 years, with repayment starting at the end of the fifth year. The Authority further noted GHIAL’s submission that the proposed cost of debt has been considered keeping in view project execution risks, regulatory approvals, global uncertainties and prevailing economic conditions.

The year-wise effective cost of debt ranges from 9.15% in FY 2026-27 to 9.88% in FY 2030-31. The Authority observed that the weighted average Cost of Debt of 9.72% is reflective of the existing debt portfolio as well as the proposed new debt for the capital projects during the Fourth Control Period.

Consultation Paper No: 02/2026-27 Page 216 of 308WEIGHTED AVERAGE COST OF CAPITAL (WACC) FOR THE FOURTH CONTROL PERIOD

8.2.6. The Authority is of the view that the Cost of Debt proposed by GHIAL is reasonable considering the nature and scale of capital projects proposed during the Fourth Control Period, including development of the Northern Precinct and airport connectivity projects. The Authority also notes that the proposed debt for new capital projects has been considered at 10% p.a., while the overall weighted average Cost of Debt for the Control Period works out to 9.72%.

8.2.7. The Authority has examined the weighted average cost of debt submitted by GHIAL for the Fourth Control Period. GHIAL has submitted a weighted average cost of debt of 9.72%. The Authority notes that GHIAL has a credit rating of AA+, and accordingly, a benchmark of SBI MCLR plus 100 basis points appears reasonable for assessing the cost of debt. The Authority further notes that the submitted weighted average cost of debt is broadly in line with the prevailing benchmark lending rates, being around the SBI MCLR as on 1 April 2026 plus 100 basis points. Accordingly, the Authority is of the view that the weighted average cost of debt of 9.72% submitted by GHIAL appears reasonable and proposes to consider the same for the purpose of tariff determination for the Fourth Control Period.

Gearing Ratio

8.2.8. The Authority notes that GHIAL has considered a gearing ratio of 48:52, i.e., 48% debt and 52% equity, for computation of the Weighted Average Cost of Capital for the Fourth Control Period and accordingly, the same has been been considered for the computation of FroR.

WACC / FRoR for the Fourth Control Period

8.2.9. Based on the above, the Authority proposes to consider the WACC / FRoR as 12.56% for the Fourth Control Period based on Cost of Equity of 15.17%, Cost of Debt of 9.72% and notional debt-equity ratio of 48%:52%, as follows:

Table 238: WACC / FRoR proposed to be considered by the Authority for the Fourth Control Period Particulars Cost of Funds Gearing Effective Rate Equity 15.17% 52.00% 7.89% Debt 9.72% 48.00% 4.67% WACC / FroR 12.56%

8.2.10. The Authority notes that since the debt-equity mix has been considered based on notional gearing of 48%:52%, the Authority proposes to not true up the debt-equity ratio based on actual gearing during the tariff determination for the next Control Period.

8.2.11. The Authority further proposes to true up the Cost of Debt for the Fourth Control Period based on actuals at the time of tariff determination for the Fifth Control Period, subject to reasonableness and efficiency.

8.3. Authority’s proposals regarding WACC for the Fourth Control Period Based on the material before it and its examination, the Authority proposes the following regarding WACC / FRoR for the Fourth Control Period:

8.3.1. To consider Cost of Equity, Cost of Debt, notional debt-equity ratio and WACC / FRoR for the Fourth Control Period as per Table 238.

8.3.2. To true up the Cost of Debt for the Fourth Control Period based on actuals (or) SBI average 1-year MCLR plus 100 bps (whichever is lower) at the time of tariff determination for the Fifth Control Period.

10.1 GHIAL’s submission regarding O&M Expenses for the Fourth Control Period

10.1.1 GHIAL has projected O&M Expenses for the Fourth Control Period based on the following assumptions

in their MYTP: • Base Year: Projected figures of FY26, the last year of the Third Control Period, has been considered as the base year for forecasting expenses for the Fourth Control Period, with applicable growth percentages applied thereon.

• Inflationary Increase: GHIAL has applied an inflationary increase to certain expense heads. A CPI inflation rate of 4.2% has been considered for the Fourth Control Period, based on the results of the 94th Round of the Survey of Professional Forecasters on Macroeconomic Indicators by the RBI.

• Impact of Northern Precinct Expansion: Following the expansion of the Southern Precinct, the commissioning of assets for the northern precinct would entail incremental cost, an additional increase of 39.23% i.e., 2/3rd of the increase in terminal area, spread equally over 2 year i.e., FY 2030 and FY

2031. The increased terminal area is expected to result in higher expenses on account of Repairs & Maintenance, Housekeeping, Manpower Hire Charges, and Security to manage the expanded operational area. Additionally, the increased passenger handling capacity is expected to drive an increase in Manpower and Administrative & General expenses.

10.2 Authority’s examination regarding Aeronautical Operation and Maintenance (O&M) Expenses for the Fourth Control Period

10.2.1 The Authority has carefully examined GHIAL's submissions related to Operation and Maintenance (O&M) Expenses for the Fourth Control Period taking into account the tariff setting principles to ensure that only the efficient, justified and reasonable expenses are allowed.

10.2.2 The Authority has reviewed the O&M Expenses and proposes to adopt the following broad methodology

for determining the Operating Expenses for the Fourth Control Period:

(i) Base year: The Authority proposes to adopt the actual aeronautical expenditure of FY 2025-26 (as per Table 135) as the base year for forecasting expenses for the Fourth Control Period.

(ii) Inflationary increase: The Authority proposes to adopt WPI inflation rate for the Fourth Control Period based on the results of 99th round of professional forecasters on macroeconomic indicators by RBI as the standard escalator across most O&M expenses, except in the case of:

▪ Employee costs, where an inflationary rate of 6% Y-o-Y has been considered; ▪ R&M cost on new asset additions, which is forecasted using the phased percentage-of-CAPEX methodology linked to asset gross block; and

(iii) Terminal Area increase factor: GHIAL's adoption of the Terminal Area Increase Factor of 39.23% (as stated in Table 241) to be applied in equal proportion over FY 2029-30 and FY 2030-31, observes that the literal application of the said proposal, a step-up of 19.61% in FY 2029-30 followed by a further step-up of 19.61% in FY 2030-31 (over the FY 2029-30 base), would result in a compounded aggregate increase of ~43%, which exceeds the intended two-thirds of the terminal area expansion (i.e., 39.23%).

The Authority hence proposes to consider terminal area increase factor of 18.01% in FY2030 and FY2031.

(iv) Manpower Growth Factor: The Authority notes that GHIAL considered increase in manpower by the factor of 39.23% (equivalent to two-thirds of the terminal area expansion) distributed evenly over FY2029 and FY2030. The Authority further notes, that the capitalisation of the Northern Precinct Terminal Building is scheduled to occur in the latter half of FY 2029-30, and the corresponding

Consultation Paper No: 02/2026-27 Page 225 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD operational requirement for additional manpower would, accordingly, arise from FY 2029-30 onwards.

Accordingly, the Authority proposes to moderate the Manpower Growth Factor to 18.01% in FY 2029- 30 and 18.01% in FY 2030-31, which on a compounded basis, yields an aggregate increase of approximately 39.23% corresponding to the two-thirds of the terminal area expansion factor adopted by GHIAL.

(v) Concession Fee, which is computed at 4% of the forecasted aeronautical revenue

10.2.3 The summary of the key growth/ escalation factors proposed to be considered by the Authority for projecting O&M expenses for the Fourth Control Period is as follows:

Table 247: Key Growth/Escalation Factors proposed to be considered by the Authority for the Fourth Control Period FY ending March FY27 FY28 FY29 FY30 FY31

Inflation: WPI 4.7% 3.6% 3.6% 3.6% 3.6% Terminal Area Increase Factor - - - 18.01% 18.01% Manpower Growth Factor - - - 18.01% 18.01%

10.2.4 As part of the tariff determination exercise for the Fourth Control Period, the Authority, has applied rationalized growth/escalation factors to the aeronautical expense heads for projection of aeronautical O&M for the Fourth Control Period.

10.2.5 The Authority proposes not to consider expenses viz. Assets written off, CSR, Donation & Contribution to Electoral Fund, Provision for Bad Debts/Doubtful advance, Bad Debts for arriving at Aeronautical Operating Expenditure for projecting the expense for the Fourth Control Period

10.2.6 The Authority has examined GHIAL’s submission regarding Aeronautical O&M for the Fourth Control

Period and has presented its examination in the subsequent paragraphs:

Manpower Expense:

10.2.7 The manpower expenses submitted by GHIAL for the Fourth Control Period is as follows:

Table 248: Aeronautical Manpower Expenses submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Staff Cost 217.50 245.08 330.02 452.58 509.54 1754.72

10.2.8 The Authority has examined GHIAL's submission in respect of the Manpower Expenses for the Fourth Control Period, and notes that GHIAL has adopted the projected costs for FY26 as the base, with the said base being escalated by applying

(a) a real year-on-year growth rate of 8% per annum, in addition to

(b) an inflation rate of 4.2% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Manpower Growth Factor of 19.61% in FY29 and 19.61% in FY30, on account of the headcount addition associated with the Northern Precinct expansion.

10.2.9 The Authority has assessed the historical Compound Annual Growth Rate (CAGR) of the Manpower expenses incurred by GHIAL during the Third Control Period (i.e., FY22 to FY26) and observes that the said expenses grew at a CAGR of ~11.4% during the Third Control Period. The Authority further observes

Consultation Paper No: 02/2026-27 Page 226 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD that the said growth rate is largely attributable to the increase in manpower headcount consequent to the terminal expansion undertaken during the Third Control Period (i.e., the commissioning of the 34 MPPA terminal expansion).

10.2.10 The Authority further takes note of the manpower count submitted by GHIAL for the Fourth Control Period

as per the table below:

Table 249: Manpower Count and Expense per Employee as submitted by GHIAL (Rs. In crores) Manpower Count at the closing of FY27 FY28 FY29 FY30 FY31 FY Aero Manpower (A) 367 367 494 648 664 Common Manpower (B) 518 518 645 792 857 GFA Ratio (C) 86.92% 87.08% 87.12% 89.37% 89.43% Total Aero Manpower (D=A+B*C) 817 818 1,056 1,356 1,431 Total Aeronautical Manpower Cost (E)

0.27 0.30 0.31 0.33 0.36 Crores)

10.2.11 The Authority notes that the manpower count and the corresponding manpower expenses submitted by GHIAL in the Multi-Year Tariff Proposal were premised on the projected FY 2025-26 base figures, the said projections being framed at the time of submission of the Tariff Proposal. The Authority observes that the actual FY 2025-26 manpower count, as subsequently furnished by GHIAL vide its submission dated

02.05.2026, is now available on record. Consistent with the regulatory principle that forward-looking projections ought to be anchored to the most recent and verifiable empirical data, the Authority accordingly proposes to adopt the actual FY 2025-26 manpower count as the base for projecting the Salaries and Wages over the Fourth Control Period, in lieu of the projected base figure originally submitted.

10.2.12 The Authority observes that Rajiv Gandhi International Airport, Hyderabad ("RGIA"), having been operational since 2008, is a mature airport with established operational systems, processes, and manpower deployment frameworks. The Authority is of the considered view that, in the case of an airport at this stage of operational maturity, the Airport Operator ought to have, in the ordinary course, implemented adequate measures to ensure operational efficiency, particularly in respect of manpower deployment, allocation, and productivity.

10.2.13 The Authority further observes that GHIAL has, in the Multi-Year Tariff Proposal, projected substantial investments in technology and digitalisation initiatives during the Fourth Control Period, inter alia, on account of automation, digital workflows, and process re-engineering. The Authority is of the considered view that the progressive implementation of the said technology investments ought to yield commensurate efficiency gains in manpower deployment, and consequently, GHIAL ought to be in a position to moderate the growth trajectory of its manpower costs over the Fourth Control Period. Allowing an escalation in Salaries and Wages materially above the prevailing rate of inflation, in the face of the said technology-

Consultation Paper No: 02/2026-27 Page 227 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD driven efficiency potential, would result in airport users bearing a cost that is neither reflective of the optimisation expected from a mature airport nor consistent with the principle of economic efficiency.

10.2.14 Having regard to (i) the operational maturity of RGIA; (ii) the substantial technology investments envisaged during the Fourth Control Period; and (iii) the historical trend of Salaries and Wages, the Authority proposes to:

(a) escalate the Salaries and Wages at a growth rate of 6% per annum, the said rate being marginally above the prevailing rate of inflation, so as to allow for a reasonable real-term escalation while preserving the efficiency imperative; and

(b) consider a manpower growth factor of 18.01% in FY 2029-30 and a further 18.01% in FY 2030-31, on account of the augmentation in operational requirements consequent upon the commissioning of the expanded terminal capacity.

10.2.15 Based on the foregoing, the Authority accordingly proposes the Manpower Count and Manpower expense

as per the table below:

Table 250: Manpower Count and Manpower expense proposed by the Authority for the Fourth Control Period (Rs. In crores) Manpower Count & Expense FY27 FY28 FY29 FY30 FY31 Total Total Aero Manpower (A) 783 783 783 924 1,090 Increase % 0% 0% 0% 18.01% 18.01% Expense per Employee (in Crores)

154.79 164.08 173.93 217.57 272.15 982.52 Expenses (C=B*A) Rates & Taxes

10.2.16 The Authority has examined GHIAL's submission in respect of the Rates and Taxes for the Fourth Control Period, and notes that GHIAL has projected the said expense by escalating the FY 2025-26 base figure at the CPI inflation rate of 4.2% per annum, supplemented by a one-time Terminal Area Increase Factor of

39.23% to be applied in equal proportion over FY30 and FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion.

10.2.17 On this basis, GHIAL has requested the Authority to consider the Rates & Taxes as per the table below:

Table 251: Aeronautical Rates & Taxes Expenses submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Rates & Taxes Expenses submitted by 8.73 9.11 9.50 12.13 15.13 54.60 GHIAL

10.2.18 The Authority, on the basis of its analysis of the historical Rates and Taxes expenses incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, on account of the inherent nature of the underlying components, comprising principally property

Consultation Paper No: 02/2026-27 Page 228 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD tax, the quanta of which are determined by the relevant governmental authorities and are subject to periodic and discretionary revisions.

10.2.19 The Authority is of the view that, given the highly variable nature of Rates and Taxes expenses, projection on the basis of historical CAGR would not yield a reliable estimate. The Authority is, accordingly, of the considered view that escalation at the prevailing rate of inflation, supplemented by the Terminal Area Increase Factor (to capture the impact of the Northern Precinct expansion on property-related taxes), constitutes a reasonable and methodologically sound basis for the projection of Rates and Taxes expenses for the Fourth Control Period.

10.2.20 The Authority hence proposes to project Rates & Taxes at inflation on rationalized FY26 base figure along with the moderated terminal area increase factor of 18.01% each in FY30 and FY31 on account of the increase in terminal area consequent to the Northern Precinct expansion.

10.2.21 Based on the foregoing, the Aeronautical portion of Rates & Taxes proposed to be considered by the

Authority for the Fourth Control Period is as follows:

Table 252: Aeronautical Rates & Taxes Expenses proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Rates & Taxes

10.2.23 The Authority analysed GHIAL’s submission regarding Bank Charges i.e. amortization of upfront fee incurred towards loans for Expansion Capex in the Fourth Control Period and notes that total Bank Charges have been projected by GHIAL, cumulatively, to be Rs. 81.14 Cr over the five years in the Fourth Control Period. The break-up of the Bank Charges submitted by GHIAL is as follows:

10.2.24 The Authority is of the view that given the adjustments proposed by the Authority in the Project Cost for Expansion Capex in the Fourth Control Period, similar adjustment was to be considered for the Bank Charges as the Debt requirement to fund the Project Cost reduces proportionately.

10.2.25 The adjustment factor proposed to be considered by the Authority for adjustment of Bank Charges proportionate to the adjustments proposed to be considered by the Authority for Expansion Capex is

0.37 0.42 0.47 0.53 0.59 2.38 GHIAL

10.2.29 The Authority has examined GHIAL's submission in respect of the Foreign Exchange Fluctuation Cost (hereinafter, "Forex Fluctuations") for the Fourth Control Period, and notes that GHIAL has projected the said cost by escalating the projected FY26 base figure at:

(a) a real year-on-year growth rate of 8% per annum, in addition to

(b) an inflation rate of 4.2% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum.

10.2.30 The Authority observes that the Forex Fluctuations during the Third Control Period have exhibited highly variable behavior, with the said cost recording negative values (i.e., foreign exchange gains) in certain years and positive values (i.e., foreign exchange losses) in others. The Authority is of the view that the said variability is inherent to the nature of the underlying item namely, the mark-to-market revaluation of foreign currency-denominated obligations which is driven by exogenous currency movements rather than by airport operations.

10.2.31 The Authority observes that GHIAL has projected costs on account of foreign exchange fluctuations for the Fourth Control Period arising from the timing differential between the date of incurrence of the underlying expense/liability and the date of its actual realisation or settlement. The Authority, however, notes that GHIAL has not furnished a detailed breakup of the said projection, including the underlying transactions, the currency exposure profile, the assumed exchange rates, and the basis of estimation.

Accordingly, the Authority proposes not to consider the said cost at this stage for the purpose of computation of the Aggregate Revenue Requirement (ARR) for the Fourth Control Period, and the same shall be trued up at the time of tariff determination for the Fifth Control Period, on the basis of the actual forex losses incurred during the Fourth Control Period, supported by appropriate documentation and prudence justification.

Security Charges

10.2.32 The Authority analysed GHIAL’s submission regarding security expenses for the Fourth Control Period and noted that GHIAL has considered costs for FY 2026 as the base for projecting the expenses for the Fourth Control Period. GHIAL has considered annual growth rate of 8% p.a. along with an inflation rate of

4.2% p.a. i.e. an effective growth rate of 12.53% p.a. In addition to this, GHIAL has considered terminal

Consultation Paper No: 02/2026-27 Page 231 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD area increase factor of 19.61% in FY30 and 19.61% in FY31 respectively. On this basis, GHIAL has

requested the Authority to consider the Security Expenses as per the table below:

Table 259: Aeronautical Security Expenses submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Security Expenses submitted by 22.69 25.58 28.80 39.73 53.51 170.31 GHIAL

10.2.33 The Authority has analysed the historical growth rates pertaining to the security expense and observes that the same have been highly inconsistent over the relevant period. The Authority further notes that there is a decline in security expenses in FY26 as compared to FY25, and that no discernible trend could be established on the basis of the past growth rates.

10.2.34 The Authority further notes that security expense head is primarily driven by the increase in security-related requirements, particularly towards engagement of outsourced security personnel and the expense is largely manpower-driven in nature.

10.2.35 The Authority notes that these security personnel are planned for deployment in terminal building as well as landside access, kerbside, common circulation areas, administrative offices, etc.

10.2.36 In view of the foregoing, and consistent with the approach adopted by the Authority in past tariff determinations, the Authority proposes to escalate the Security expenses over the Fourth Control Period at the rate of 6% on rationalized FY26 base figure, marginally higher than the inflation. Further, the Authority proposes to apply an adjusted terminal area expansion factor of 18.01% in FY30 and 18.01% in FY31, so as to align with the commissioning of the Northern Precinct Terminal.

10.2.37 The Aeronautical Security Expense proposed to be considered by the Authority for the Fourth Control

Period is as follows:

Table 260: Aeronautical Security Expense proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Security

18.38 19.48 20.65 25.83 32.31 116.65 Expenses Increase % 6.0% 6.0% 6.0% 25.1% 25.1% Repairs & Maintenance

10.2.38 The Authority analysed GHIAL’s submission regarding Repairs and Maintenance expenses (Building, Plant & Machinery, IT and Others) which have been projected considering 1.5% of asset additions, inflation rate of 4.6% p.a., along with terminal area expansion factor of 19.63 % and 19.63 % in FY30 and FY31 respectively. On this basis, GHIAL has requested the Authority to consider the R&M as per the table below:

Consultation Paper No: 02/2026-27 Page 232 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD Table 261: R&M Expense submitted by GHIAL for the Fourth Control Period FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical R&M Expenses

142.17 153.65 162.17 203.42 253.57 914.99 submitted by GHIAL

10.2.39 The Authority has analysed the historical growth rates pertaining to the R&M expense and observes that the same have been highly inconsistent over the relevant period. The Authority further notes that there is a decline in R&M expenses in FY26 in comparison to the previous year, and that no discernible trend could be established on the basis of the past growth rates.

10.2.40 Having regard to the foregoing examination, and consistent with the approach adopted by the Authority in past tariff determinations (including the Tariff Order(s) for the Third Control Period), the Authority proposes to project the Aeronautical Repairs and Maintenance Expenses for the Fourth Control Period on

the following basis: a. Base Component: The Repairs and Maintenance Expenses for the FY26 base year, escalated at the inflation rates set out at Table 240 of this Consultation Paper b. Incremental Component on New Asset Additions: An additional allowance equivalent to 0.5% of the value of the asset additions capitalized during each year of the Fourth Control Period, to address the incremental Repairs and Maintenance expenditure attributable to the said additions.

10.2.41 The Aeronautical Repair & Maintenance Expense proposed by the Authority for the Fourth Control Period

is as per the table below:

Table 262: R&M Expense proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) Total FY ending March FY26 FY27 FY28 FY29 FY30 FY31 (FY27- FY31) Asset Addition (A) 720.96 332.76 130.87 10915.64 157.91 Incremental Component on new asset addition 3.60 1.66 0.65 54.58 0.79 61.29 (B= A*0.5%) Base Component (C) 113.37 122.39 128.40 133.65 190.93 Inflation (D) 4.7% 3.6% 3.6% 3.6% 3.6% Total Aeronautical R&M Expenses 113.37 122.31 128.37 133.65 193.04 200.78 778.14 E=B+C*(1+D) Increase % 7.9% 4.96% 4.11% 44.44% 4.01% Stores & Spares (Consumables)

10.2.42 The Authority has examined GHIAL's submission in respect of the Stores and Spares Expenses for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY26 base figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum,

Consultation Paper No: 02/2026-27 Page 233 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Terminal Area Increase Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis,

GHIAL has requested the Authority to consider the Consumables expense as per the table below:

Table 263: Aeronautical Stores & Spares (Consumables) submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Stores & Spares (Consumables) 17.69 19.91 22.40 30.19 40.64 130.83 submitted by GHIAL

10.2.43 The Authority, on the basis of its analysis of the historical Stores and Spares Expenses incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in FY25 and FY26.

10.2.44 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Stores and Spares Expenses, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical experience.

10.2.45 The Authority hence proposes to consider escalation at inflation rate on rationalized FY26 base figure along with consideration of moderated terminal area expansion factor of 18.01% and 18.01% in FY30 and FY31 respectively for projecting Stores & Spares expenses.

10.2.46 The Aeronautical Stores & Spares (Consumables) Expense proposed by the Authority for the Fourth

Control Period is as per the table below:

Table 264: Aeronautical Stores & Spares (Consumables) Expense proposed by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Stores &

10.2.47 The Authority has examined GHIAL's submission in respect of the insurance expenses for the Fourth Control Period, and notes that GHIAL has projected the key insurance policies for the airport including Large Risk Policy (Property Damage & Business Interruption (BI)), AOL/3rd Party Liability Policy, Terrorism Policy and Cyber Security Policy by escalating the projected FY26 base figure at 10%. On this basis, GHIAL has submitted the insurance expense as per the table below:

Table 265: Aeronautical Insurance Expense submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Insurance

17.65 20.50 23.65 35.81 49.83 147.44 submitted by GHIAL

Consultation Paper No: 02/2026-27 Page 234 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD

10.2.48 GHIAL has computed premium on Large Risk Policy based on the closing Gross Block and gross revenue during the policy period. The premiums on other insurance policies are escalated at 10% p.a.

10.2.49 The Authority undertook an analysis of the historical trend of insurance premium expenditure actually incurred by GHIAL during the Third Control Period. The Authority observed that the insurance premium has registered a Compounded Annual Growth Rate (CAGR) of 13.8% during the period FY22 to FY26, as derived from the audited/actual figures submitted by GHIAL.

10.2.50 Upon comparing the proposed escalation of 10% per annum with the historical CAGR of 11.8% (FY22- FY25), the Authority observes that the escalation sought by GHIAL for the Fourth Control Period is lower than the actual growth trend witnessed during the Third Control Period. The proposed rate is therefore conservative in nature and does not result in any over-projection of costs to be recovered from airport users.

10.2.51 The Authority notes that the said growth in premium is broadly attributable to the expansion in the insured asset base of the airport consequent to the ongoing capacity augmentation and capital expenditure program and finds the escalation of 10% p.a. on premiums for other insurance policies is reasonable.

10.2.52 The Aeronautical Insurance Expense proposed by the Authority for the Fourth Control Period is as per the

table below:

Table 266: Aeronautical Insurance Expenses proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Insurance

8.95 9.85 10.84 11.92 13.11 54.67 Expense Increase % 10.0% 10.0% 10.0% 10.0% 10.0% Land Lease Rent

10.2.53 The Authority has examined GHIAL's submission in respect of the Rent Expenses for the Fourth Control Period, and notes that GHIAL has projected the said expenses, comprising principally the lease rent payable to the Government of Telangana, by applying a contractual escalation of 5% on a year-on-year basis, consistent with the contractual provisions governing the said rentals. On this basis, GHIAL has submitted

the Rent expense as per the table below:

Table 267: Aeronautical Land Lease Rent Expenses submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Land Lease Rent Expenses submitted by 16.37 17.20 18.07 19.26 20.23 91.13 GHIAL

10.2.54 The Authority notes that as per the Land Lease Agreement, GHIAL is liable to pay Rent towards the leased at 5% yearly escalation to the Government of Telangana and is of the view that GHIAL’s projection of Aeronautical Land Lease Rent Expenses based on contractual rate is reasonable and accordingly proposes to consider GHIAL’s submission.

Consultation Paper No: 02/2026-27 Page 235 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD

10.2.55 The Aeronautical Land Lease Rent expenses proposed to be considered by the Authority for the Fourth

Control Period is as follows:

Table 268: Aeronautical Land Lease Rent Expenses proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Land Lease

10.2.56 The Authority has examined GHIAL's submission in respect of the Manpower Hire Charges for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY26

base figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Manpower Growth Factor of 19.61% in FY29 and 19.61% in FY30, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis,

GHIAL has submitted the Manpower Hire Charges as per the table below:

Table 269: Aeronautical Manpower Hire Charges submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Manpower Hire Charges submitted by 117.54 132.34 178.17 241.68 272.03 941.77 GHIAL

10.2.57 The Authority, on the basis of its analysis of the historical Manpower Hire Charges incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in FY23.

10.2.58 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Manpower Hire Charges, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical experience.

10.2.59 The Authority notes that this expense pertains to manpower deputation and outsourced manpower services deployed for operational and project-related requirements. The key components include manpower deputation for general Capex activities, E&M support services for landscaping works in landside and airside areas, manpower deployment for landside building operations, and manpower supply for baggage handling and other operational support functions.

10.2.60 In view of the foregoing, and consistent with the approach adopted by the Authority in past tariff determinations, the Authority proposes to escalate the Manpower Hire charges over the Fourth Control Period at the rate of 6% on rationalized FY26 base figure, marginally higher than the inflation. Further, the

Consultation Paper No: 02/2026-27 Page 236 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD Authority proposes to apply an adjusted terminal area expansion factor of 18.01% in FY30 and 18.01% in FY31, so as to align with the commissioning of the Northern Precinct Terminal.

10.2.61 The Aeronautical Manpower Hire Charges proposed by the Authority for the Fourth Control Period is as

per the table below:

Table 270: Aeronautical Manpower Hire Charges proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Manpower

92.39 97.93 103.81 129.85 162.44 586.42 Hire Charges Increase % 6.0% 6.0% 6.0% 25.1% 25.1% Housekeeping Expenses

10.2.62 The Authority has examined GHIAL's submission in respect of the Housekeeping Expenses for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY 2025- 26 base figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Terminal Area Increase Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis,

GHIAL has submitted the Housekeeping expense as per the table below:

Table 271: Aeronautical Housekeeping expense submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Housekeeping Charges submitted by 43.87 49.38 55.57 75.03 101.01 324.86 GHIAL

10.2.63 The Authority, on the basis of its analysis of the historical Housekeeping Expenses incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable on account of full annualized impact of the housekeeping contract for the expanded terminal is reflecting in FY26 and a one-time deep cleaning activity undertaken (amounting Rs 9 Crores) during FY26 across the old terminal areas to align hygiene and service standards with the newly expanded facilities.

10.2.64 The Authority observes that the said one-time deep cleaning expenditure is, by its very nature, non-recurring and non-representative of the steady-state housekeeping cost profile reasonably expected to obtain over the Fourth Control Period. Accordingly, the inclusion of the said one-time cost in the FY 2025-26 base figure

Consultation Paper No: 02/2026-27 Page 237 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD would result in an artificially elevated base, which, when subjected to compounding escalation over the Fourth Control Period, would yield an unwarranted build-up of Housekeeping Expenses.

10.2.65 The Authority accordingly proposes to revise the FY 2025-26 base figure by excluding the one-time deep cleaning expenditure for projection of Housekeeping cost for the Fourth Control Period.

10.2.66 Having regard to the foregoing examination, and consistent with the approach adopted by the Authority in past tariff determinations (including the Tariff Order(s) for the Third Control Period), the Authority proposes escalation at inflation rate on rationalized FY26 base figure, along with the moderated terminal area increase factor of 18.01% in FY30 and 18.01% in FY31 for projection of Housekeeping Expense for the Fourth Control Period.

10.2.67 The Aeronautical Housekeeping Expenses proposed by the Authority for the Fourth Control Period is as

per the table below:

Table 272: Aeronautical Housekeeping Charges proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Housekeeping

44.85 46.46 48.14 58.85 71.95 270.25 Charges Increase % -13.5% 3.6% 3.6% 22.3% 22.3%

Admin and General Expenses:

10.2.68 The Admin and General Expenses comprise of Professional and Consultancy Expenses, Recruitment Charges, Printing and Stationery, Travelling and Conveyance, Communication Costs, Director’s Sitting Fee, Advertising and Sales Promotion, Corporate Cost Allocation, Payment to Auditors and Other Admin Expenses.

10.2.69 Authority’s Examination of the expenses under Admin & General Expenses are in the subsequent paragraphs.

Advertisement & Business Promotions

10.2.70 The Authority has examined GHIAL's submission in respect of the Advertisement & Business Promotions Expenses for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY26 base figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Terminal Area Increase Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis, GHIAL has submitted the Advertisement & Business Promotion expense as per the table below:

Consultation Paper No: 02/2026-27 Page 238 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD Table 273: Aeronautical Advertisement & Business promotion submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Advertisement & Business promotion 23.67 26.64 30.00 40.31 54.04 174.66 submitted by GHIAL

10.2.71 The Authority, on the basis of its analysis of the historical Advertisement & Business Promotions expense incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in FY26.

10.2.72 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Advertisement & Business Promotions expense, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical precedent.

10.2.73 The Authority notes that RGIA is a mature airport operating in a large metropolitan, technology-oriented, and commercially developed environment, having already established its brand identity, passenger engagement framework, and commercial ecosystem during the preceding Control Periods. In such a steady- state operational context, Advertising & Business Promotion expenses are recurring in nature and are not driven by the expansion of the airport's operations, and are not, therefore, expected to escalate in proportion to traffic growth or terminal area augmentation. Accordingly, the Authority is of the considered view that the prevailing rate of inflation constitutes the most appropriate escalation factor for projection of the said expenses for the Fourth Control Period, being consistent with the maturity profile of the airport.

10.2.74 The Authority, pursuant to the classification and apportionment framework adopted for True up of Advertisement & Business promotion expenses for the Third Control Period, has projected the Advertisement and Business Promotion expenses for the Fourth Control Period by escalating the rationalized FY26 figure at inflation rate.

10.2.75 The Aeronautical Advertisement & Business promotion expenses to be considered by the Authority for the

Fourth Control Period is as follows:

Table 274: Aeronautical Advertisement & Business Promotion Expenses proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Advertisement

8.66 8.97 9.29 9.63 9.97 46.52 & Business promotion Increase % 4.7% 3.6% 3.6% 3.6% 3.6% Professional & Consultancy Charges

10.2.76 The Authority has examined GHIAL's submission in respect of the Professional & Consultancy Charges for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY26 base figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum,

Consultation Paper No: 02/2026-27 Page 239 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Terminal Area Increase Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis, GHIAL has submitted the Advertisement & Business Promotion expense as per the table below:

Table 275: Aeronautical Professional and Consultancy expenses submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Professional and Consultancy expenses 52.29 58.86 66.30 88.95 118.80 385.20 submitted by GHIAL

10.2.77 The Authority, on the basis of its analysis of the historical Professional & Consultancy Charges incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in FY24 and FY26.

10.2.78 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Professional & Consultancy Charges, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical experience.

10.2.79 The Authority is further of the considered view that the Professional & Consultancy Charges do not bear a direct or proportionate correlation with the increase in the terminal area at the Airport. The said position is borne out by the historical experience during the Third Control Period itself, wherein the said expense head, in fact, registered a decrease in FY 2023-24, being the year of capitalisation of the 34 MPPA terminal expansion, notwithstanding the substantial augmentation in the terminal area in the said year.

10.2.80 The Authority has examined the details of Legal costs incurred by GHIAL during the Third Control Period.

The Authority is of the view that such legal consultancy expenses are not critical or necessary for the Aeronautical Operations of the Airport and are, by their nature, expenses incurred towards legal cases / proceedings with other stakeholders. Such expenses do not add value to the services offered to airport users and, therefore, ought not to form part of the Aeronautical cost base for tariff determination.

10.2.81 The Authority has also noted that even in the concession agreements executed by the Government of India for recent airports, legal expenses are excluded from the Operating Expenses considered as pass-through for the purpose of tariff determination. Accordingly, the Authority proposes to exclude the legal expenses incurred by GHIAL from the base year expenditure considered for projecting Professional and Consultancy / Consultancy and Legal costs for the Fourth Control Period.

10.2.82 The Authority hence proposes to exclude legal expenses of Rs. 1.71 Crores incurred by GHIAL in FY 2025- 26 from the rationalized base year and escalate the balance Professional & Consultancy costs year-on-year by inflation.

10.2.83 Based on the foregoing, the Aeronautical Professional & Consultancy Charges expenses proposed to be

considered by the Authority for the Fourth Control Period is as follows:

Table 276: Aeronautical Professional and Consultancy expenses proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores)

10.2.84 The Authority has examined GHIAL's submission in respect of the Corporate Cost Allocation for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the FY26 base figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Terminal Area Increase Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis,

GHIAL has submitted the Corporate Cost Allocation as per the table below:

Table 277: Aeronautical Corporate Cost submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Corporate Cost

69.08 77.77 87.61 117.50 156.77 508.74 submitted by GHIAL

10.2.85 The Authority notes that the Corporate Cost arises from shared corporate functions performed by GAL (the holding company) through Centers of Excellence for the multi-airport group, with proportionate allocation to RGIA on a shared services basis.

10.2.86 The Authority further notes GHIAL’s submission that the allocated costs are largely composed of group- level employee costs, consultancy services, capability-building initiatives, and business promotion expenditure, all of which are headquarter-centric in nature and do not have a direct link/connection with the level of airport operation or the extent of terminal area of the airport.

10.2.87 The Authority, on the basis of its analysis of the historical Corporate Cost Allocation incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in FY23.

10.2.88 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Corporate Cost Allocation, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical experience.

10.2.89 The Authority notes that GHIAL has adjusted the Corporate Cost Allocation to factor in the increase in the passenger terminal area consequent to the ongoing capacity expansion at the airport. The Authority, however, is of the considered view that the Corporate Cost Allocation is predominantly driven by the employee cost at the corporate/headquarter level, which does not bear a direct connection with the increase in the terminal building area. Accordingly, the Authority does not propose to escalate the said allocation on the basis of terminal area expansion, and instead proposes to project the same at an annual escalation of 6% on rationalized FY26 base figure, in line with the methodology discussed in the foregoing paragraphs.

Consultation Paper No: 02/2026-27 Page 241 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD Further detailed working and basis of allocation of corporate cost needs to be submitted by GHIAL to assess the reasonableness and efficiency of corporate cost allocation by GHIAL for True up during the tariff determination of the Fifth Control Period.

10.2.90 Based on the foregoing, the Aeronautical Corporate Cost Allocation expenses proposed to be considered

by the Authority for the Fourth Control Period is as follows:

Table 278: Corporate Cost submitted by GHIAL and proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Corporate Cost 76.07 80.63 85.47 90.60 96.03 428.79 Increase % 6.0% 6.0% 6.0% 6.0% 6.0% Communication Cost

10.2.91 The Authority has examined GHIAL's submission in respect of the Communication Cost for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY26

base figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Terminal Area Increase Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis,

GHIAL has submitted the Communication Cost as per the table below:

Table 279: Aeronautical Communication Cost submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Communication Cost 2.32 2.61 2.94 4.05 5.46 17.39 submitted by GHIAL

10.2.92 The Authority notes that Communication costs include the Leased Line Charges/VPN for GHIAL administration purposes across RGI airport, mobile expenses for operating staff. These costs are non- recoverable from any concessionaires.

10.2.93 The Authority, on the basis of its analysis of the historical Communication Cost incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in FY24.

10.2.94 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Communication Cost, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical experience.

10.2.95 The Authority is further of the considered view that the Communication Cost do not bear a direct or proportionate correlation with the increase in the terminal area at the Airport. The said position is borne out

Consultation Paper No: 02/2026-27 Page 242 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD by the historical experience during the Third Control Period itself, wherein the said expense head, in fact, registered a decrease in FY 2023-24, being the year of capitalisation of the 34 MPPA terminal expansion, notwithstanding the substantial augmentation in the terminal area in the said year.

10.2.96 Having regard to the foregoing examination, and consistent with the approach adopted by the Authority in past tariff determinations (including the Tariff Order(s) for the Third Control Period), the Authority proposes escalation at inflation rate on rationalized FY26 base figure, for projection of Communication Cost for the Fourth Control Period.

10.2.97 The Aeronautical Communication Cost proposed to be considered by the Authority for the Fourth Control

Period is as follows:

Table 280: Communication Cost proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical

2.03 2.11 2.18 2.26 2.34 10.92 Communication Cost Increase % 4.7% 3.6% 3.6% 3.6% 3.6% Printing & Stationery

10.2.98 The Authority has examined GHIAL's submission in respect of the Printing & Stationery Expense for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY26 base figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Terminal Area Increase Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis, GHIAL has submitted the Aeronautical Printing & Stationery expense as per the table below:

Table 281: Aeronautical Printing and Stationery expenses submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Printing and Stationery expenses 0.73 0.83 0.93 1.28 1.72 5.49 submitted by GHIAL

10.2.99 The Authority, on the basis of its analysis of the historical Printing & Stationery Expense incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in FY25.

10.2.100 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Printing & Stationery Expense, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical experience.

10.2.101 The Authority further observes that GHIAL, in its Tariff Proposal, has placed on record its intent to undertake comprehensive digitalisation and automation of airport operational processes during the Fourth

Consultation Paper No: 02/2026-27 Page 243 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD Control Period. The Authority is of the view that the progressive implementation of such digital initiatives ought to result in a commensurate and tangible reduction in the consumption of physical printing and stationery materials across the airport's operational and administrative functions.

10.2.102 Having regard to the foregoing examination, and consistent with the approach adopted by the Authority in past tariff determinations (including the Tariff Order(s) for the Third Control Period), the Authority proposes escalation at inflation rate on rationalized FY26 base figure, for projection of Printing & Stationery Expense for the Fourth Control Period.

10.2.103 The Aeronautical Printing & Stationery Expense proposed to be considered by the Authority for the Fourth

Control Period is as follows:

Table 282: Printing & Stationery Cost proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Printing and

0.66 0.68 0.71 0.73 0.76 3.54 Stationery expenses Increase % 4.7% 3.6% 3.6% 3.6% 3.6% Recruitment Charges

10.2.104 The Authority has examined GHIAL's submission in respect of the Recruitment Charges for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY26

base figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Manpower Growth Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis,

GHIAL has submitted the Aeronautical Recruitment charges as per the table below:

Table 283: Aeronautical recruitment Charges submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Recruitment expenses submitted by 6.71 7.56 8.51 11.42 15.24 49.44 GHIAL

10.2.105 The Authority notes GHIAL pays the recruiting agency a minimum of 2 months’ salary (up to 6 months’ salary, based on the category of the employees) of the newly joined employee based on the agreed CTC and has assumed these costs to increase in line with the manpower growth.

10.2.106 The Authority, on the basis of its analysis of the historical Recruitment Charges incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in FY26.

Consultation Paper No: 02/2026-27 Page 244 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD

10.2.107 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Recruitment Charges, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical experience.

10.2.108 Having regard to the foregoing examination, and consistent with the approach adopted by the Authority in past tariff determinations (including the Tariff Order(s) for the Third Control Period), the Authority proposes escalation at inflation rate on rationalized FY26 base figure, along with moderated Manpower Growth Factor of 18.01% in FY30 and 18.01% in FY31 for projection of Recruitment Charges for the Fourth Control Period.

10.2.109 The Aeronautical Recruitment Charges proposed to be considered by the Authority for the Fourth Control

Period is as follows:

Table 284: Aeronautical Recruitment expenses proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Recruitment

4.71 4.88 5.05 6.18 7.55 28.36 expenses Increase % 4.7% 3.6% 3.6% 22.3% 22.3% Travelling & Conveyance

10.2.110 The Authority has examined GHIAL's submission in respect of the Travelling & Conveyance Expense for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY26 base figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Terminal Area Increase Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis GHIAL has submitted the Travelling & Conveyance expense as per the table below:

Table 285: Aeronautical Travelling & Conveyance expenses submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Travelling & Conveyance expenses 53.04 59.72 67.26 90.24 120.48 390.74 submitted by GHIAL

10.2.111 The Authority, on the basis of its analysis of the historical Travelling & Conveyance Expense incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in FY26.

Consultation Paper No: 02/2026-27 Page 245 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD

10.2.112 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Travelling & Conveyance Expense, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical experience.

10.2.113 Having regard to the foregoing examination, and consistent with the approach adopted by the Authority in past tariff determinations (including the Tariff Order(s) for the Third Control Period), the Authority proposes escalation at inflation rate on rationalized FY26 base figure for projection of Travelling & Conveyance Expense for the Fourth Control Period.

10.2.114 The Aeronautical Travelling & Conveyance Expense proposed to be considered by the Authority for the

Fourth Control Period is as follows:

Table 286: Travelling & Conveyance expenses proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Travelling &

10.2.115 The Authority has examined GHIAL's submission in respect of the Directors' Sitting Fee Expenses for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY26 base figure at the CPI inflation rate of 4.2% per annum, without applying any real growth factor or other escalation. On this basis, GHIAL has submitted the Directors Sitting Fee as per the table below:

Table 287: Aeronautical Directors Sitting Fee submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Directors Sitting Fee submitted by 0.18 0.19 0.19 0.20 0.21 0.97 GHIAL

10.2.116 The Authority is of the view that GHIAL’s submission of projecting the Directors Sitting Fee with inflation as escalation rate is justifiable and hence proposes to project the Aeronautical Directors' Sitting Fee Expenses for the Fourth Control Period by escalating the rationalized FY26 base figure only at the inflation rate.

Table 288: Directors Sitting Fee proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Directors

10.2.117 The Authority has examined GHIAL's submission in respect of the Payment to Auditors for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY26

Consultation Paper No: 02/2026-27 Page 246 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD base figure at the CPI inflation rate of 4.2% per annum, along with real growth factor of 8%. On this basis,

GHIAL has submitted the Payment to Auditor expense as per the table below:

Table 289: Aeronautical Payment to Auditor submitted by GHIAL for the Fourth Control Period (Rs. In Crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Payment to

0.90 1.01 1.14 1.28 1.43 5.75 Auditor

10.2.118 The Authority, on the basis of its analysis of the historical Payment to Auditors incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in FY24.

10.2.119 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Payment to Auditors, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical experience.

10.2.120 Having regard to the foregoing examination, and consistent with the approach adopted by the Authority in past tariff determinations (including the Tariff Order(s) for the Third Control Period), the Authority proposes escalation at inflation rate on rationalized FY26 figure for projection of Payment to Auditors Expense for the Fourth Control Period.

Table 290: Payment to Auditor Fee proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Payment to

1.17 1.22 1.26 1.30 1.35 6.30 Auditor Increase % 4.7% 3.6% 3.6% 3.6% 3.6%

10.2.121 The Aeronautical Payment to Auditors Expenses proposed for consideration by the Authority for the Fourth Control Period are marginally higher than GHIAL’s submission, owing to the higher actual base figure for FY26 used in projecting the said expenses.

Other Admin Expenses

10.2.122 The Authority has examined GHIAL's submission in respect of the Other Admin Expenses for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the projected FY26

base figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Terminal Area Increase Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis,

GHIAL has submitted Other Admin Expense as per the table below:

Table 291: Aeronautical Other Admin Expense submitted by GHIAL for the Fourth Control Period (Rs. In crores)

Consultation Paper No: 02/2026-27 Page 247 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Other Admin Expense

5.71 6.44 7.25 9.95 13.40 42.75 submitted by GHIAL

10.2.123 The Authority notes that the expenses classified by GHIAL under the head "Other Administrative Expenses" comprise the following components: • Membership fees paid to professional bodies such as CAPA (Centre for Aviation), CFO Next, APAO (Association of Private Airport Operators), CEO Next, and similar industry/professional forums;

• Subscription charges for books, periodicals, and professional publications; and • Meeting and seminar expenses incurred for internal team meetings and related engagements.

10.2.124 The Authority, on the basis of its analysis of the historical Other Admin Expenses incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in certain years.

10.2.125 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Other Admin Expenses, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical experience.

10.2.126 The Authority, in the absence of a detailed sub-component-wise break-up of the expenses booked under this head and the consequent inability to undertake a granular prudence and efficiency assessment, proposes to project the expense for the Fourth Control Period by adopting 50% of the rationalized FY26 base as the starting point, with annual escalation at the prevailing inflation rate.

10.2.127 Having regard to the foregoing examination, the Aeronautical Other Admin Expenses proposed to be

considered by the Authority for the Fourth Control Period is as follows:

Table 292: Other Admin Expense proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Other Admin Expense 3.08 3.19 3.30 3.42 3.54 16.53 Increase % -47.7% 3.6% 3.6% 3.6% 3.6% CSR Expenses

10.2.128 The Authority notes GHIAL’s submissions regarding Corporate Social Responsibility (CSR) expenses which has been considered at the rate of 2% of the average PAT for the preceding three years.

10.2.129 The Authority took cognizance of the statutory provisions of the Companies Act, 2013 towards allowance

of CSR expenses and the extract of the same has been provided below: i. Section 135 (1) of Companies Act, 2013 states that ‘Every company having net worth of rupees five hundred crore or more, or turnover of rupees one thousand crore or more or a net profit of rupees five crore or more during immediately preceding financial year shall constitute a Corporate Social Responsibility Committee of the Board consisting of three or more directors, out of which at least one shall be an independent director.’ Further section 135(5) states that ‘The Board of every company referred in section 135(1), shall ensure that the company spends, in every financial year, at least two percent of the average net profits of the company made during

Consultation Paper No: 02/2026-27 Page 248 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD the three immediately preceding financial years, in pursuance of its Corporate Social Responsibility’.

10.2.130 In this regard, the Authority is of the view that the CSR is a mandatory Social Responsibility of the Company (as per Section 135(1) of Companies Act). As the CSR expenditure is to be incurred by Companies out of their net profits, it is to be regarded as an element of appropriation of Net Profits and not as a part of their Operating Expenditure. Therefore, CSR expenses could not be construed as a passthrough expenditure of the companies, otherwise, it would defeat the very purpose of the social responsibility entrusted on the companies.

10.2.131 Further, Section 37(1) of Income Tax Act also disallows CSR expenses, as these are not considered expenses incurred wholly and exclusively for the purpose of business of the entity.

10.2.132 The Authority proposes not to consider CSR expenses as part of Aeronautical O&M expenses for the Fourth Control Period.

Operating Expenses:

10.2.133 The Authority has examined GHIAL's submission in respect of the Other Operating Expenses for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the FY26 base

figure at:

(a) an inflation rate of 4.2% per annum, in addition to

(b) a real year-on-year growth rate of 8% per annum, resulting in a combined effective annual escalation of approximately 12.53% per annum. In addition, GHIAL has proposed a one-time Terminal Area Increase Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis,

GHIAL has submitted the Operating Expenses as per the table below:

Table 293: Aeronautical Operating Expenses submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Operating Expenses 5.69 6.40 7.21 9.69 12.99 41.98

10.2.134 The Authority notes that operating expenses relate to day-to-day operational support services provided by various operators, including the GA Terminal Operator and Car Park Operator.

10.2.135 The Authority, on the basis of its analysis of the historical Other Operating Expenses incurred by GHIAL during the Third Control Period, observes that the year-on-year growth rates of the said expense were highly variable, with the said expenses recording negative growth in FY23.

10.2.136 The Authority is of the view that, given the highly variable and bidirectional nature of the year-on-year movements in Other Operating Expenses, the application of a real growth rate of 8% per annum to the said expense is not supported by the historical experience.

10.2.137 Having regard to the foregoing examination, and consistent with the approach adopted by the Authority in past tariff determinations (including the Tariff Order(s) for the Third Control Period), the Authority

Consultation Paper No: 02/2026-27 Page 249 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD proposes escalation at inflation rate on rationalized FY26 figure for projection of Other Operating Expenses for the Fourth Control Period.

10.2.138 The Aeronautical Other Operating Expenses proposed to be considered by the Authority for the Fourth

Control Period is as follows:

Table 294: Operating Expenses proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Operating Expense 2.98 3.09 3.20 3.32 3.44 16.03 Increase % 4.7% 3.6% 3.6% 3.6% 3.6% Collection Charges

10.2.139 The Authority has examined GHIAL’s submission regarding Collection Charges for the Fourth Control Period wherein the expenses are escalated at the passenger growth rate.

Table 295: Aeronautical Collection Charges submitted by GHIAL for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Collection Charges

6.57 7.38 8.38 9.00 9.67 41.00 submitted by GHIAL

10.2.140 The Authority is of the view that GHIAL’s submission of projecting the Collection Charges with PAX growth as escalation factor is justifiable and hence proposes to project the Collection Charges for the Fourth Control Period by escalating the FY26 base figure only at the PAX growth rate for the Fourth Control Period.

Table 296: Collection Charges proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Aeronautical Collection Charges 6.79 7.63 8.65 9.30 9.99 42.36 Increase % 14.7% 12.4% 13.4% 7.5% 7.4%

10.2.141 The Aeronautical collection charges proposed by the Authority are higher than those submitted by GHIAL, the said variation is attributable to the application of the FY 2026-27 passenger growth rate to the actual FY 2025-26 passenger base, as against the application of the said growth rate to the projected FY 2025- 26 passenger base as adopted by GHIAL in its Multi-Year Tariff Proposal.

Utility Expense

10.2.142 The Authority has examined GHIAL's submission in respect of the Utility Expenses for the Fourth Control Period, and notes that GHIAL has projected the said expenses by escalating the FY26 base figure at an inflation rate of 4.2% per annum. In addition, GHIAL has proposed a one-time Terminal Area Increase Factor of 19.61% in FY30 and 19.61% in FY31, on account of the increase in terminal area consequent to the Northern Precinct expansion. On this basis, GHIAL has submitted the Utility Expenses as per the

table below:

Table 297: Utility Expenses submitted by GHIAL for the Fourth Control Period (Rs. In crores)

Consultation Paper No: 02/2026-27 Page 250 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD FY ending March FY27 FY28 FY29 FY30 FY31 Total Utility Expense 65.29 68.03 70.89 88.36 110.13 402.7

10.2.143 The Authority has examined the methodology adopted by GHIAL for projecting the Utility Expenses over the Fourth Control Period. GHIAL has proposed to escalate the said expenses considering two principal drivers, namely:

(i) the prevailing rate of inflation, to account for the year-on-year increase in tariffs of utilities such as power, water, and other allied services; and

(ii) the expansion in the Terminal Area of RGIA consequent to the ongoing capacity augmentation, which results in a corresponding increase in the consumption of utilities (lighting, HVAC, water, etc.).

10.2.144 The Authority further notes that Utility Expenses reflected in the said table represent the net expenses borne by GHIAL after recovery of the proportionate utility charges from concessionaires, commercial occupants, and other third-party users of the airport infrastructure.

10.2.145 The Authority further notes that the percentage of utility cost recovery from concessionaires has registered a noticeable improvement during FY26 as compared to the preceding year. Electricity recovery has increased to 55.32% in FY26 from 48.14% from the previous year and water recovery has increased to

33.62% in FY26 from 27.09% in FY25.

10.2.146 The Authority, considering the improving trajectory of utility cost recovery from concessionaires, proposes to project the recovery percentages for the Fourth Control Period at the FY26 actual levels of

55.32% (electricity) and 33.62% (water) as the minimum baseline, with the expectation that GHIAL shall progressively enhance the said recoveries through improved metering, billing, and contractual enforcement.

10.2.147 The Authority notes that linking utility expenses to the Terminal Area is a rational and technically sound basis, inasmuch as utility consumption at an airport terminal is directly correlated with the built-up area being operated, maintained, illuminated, and air-conditioned. The use of inflation as a secondary escalator further captures the price-side movement, independent of the volume/area-side movement.

10.2.148 In view of the foregoing, the Authority finds the growth rate considered by the Operator to be justifiable and reasonable. Accordingly, the Authority proposes to project the Utility Expenses for the Fourth Control

Period in the following manner:

(i) Base Year: Actual Utility Expense incurred in FY26 shall be taken as the base.

(ii) Escalation – Price Component: The base figure shall be escalated annually by the prevailing inflation rate over the Control Period.

(iii) Escalation – Volume/Area Component: In addition to the inflation-linked escalation, a moderated Terminal Area increase factor of 18.01% shall be applied in FY30 and again in FY31, to capture the step-up in utility consumption arising from the commissioning of the expanded terminal facilities.

10.2.149 The Authority has taken note of the detailed breakup of utility expense for FY26 and has projected the

10.2.150 Based on the above, Utility expense proposed to be considered by the Authority for the Fourth Control

Period is as per the table below:

Consultation Paper No: 02/2026-27 Page 252 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD Table 299: Utility expense proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Utility Expense 50.11 51.91 53.78 65.75 80.39 301.94 Increase % 4.7% 3.6% 3.6% 22.3% 22.3% CGF Expense

10.2.151 The Authority notes that GHIAL, in its Multi-Year Tariff Proposal (MYTP) for the Fourth Control Period, has treated Cargo, Ground Handling and Fuel Farm (CGF) Services as Non-Aeronautical in nature, and has not submitted the operating expenses pertaining to CGF operations for the purpose of computation of the Aggregate Revenue Requirement (ARR).

10.2.152 The Authority notes that the expenditure submitted by GHIAL under the head Cargo, Ground Handling and Fuel Farm (CGF) primarily pertains to expenses relating to the Fuel Farm facility. The Authority observes that, in respect of Cargo and Ground Handling activities, dedicated concessionaires have been appointed, who are responsible for undertaking the related capital expenditure as well as operating and maintenance expenditure for the respective facilities/services. Accordingly, the operating expenses of the Airport Operator under the CGF head are not materially attributable to Cargo and Ground Handling activities. However, the Fuel Farm facility is operated by the Airport Operator itself, and the related operating and maintenance expenses, including manpower, utilities, repair and maintenance, consumables, safety compliance and other operational costs, are therefore incurred by GHIAL. Hence, the Authority has considered the expenditure under the CGF head as being primarily related to Fuel Farm operations.

10.2.153 The Authority further observes that fuel offtake at an airport is closely linked to the level of aircraft operations and therefore has a correlation with growth in Air Traffic Movements (ATMs). As the number of ATMs increases, the scale of fueling operations also increases, resulting in higher operational requirements in terms of manpower deployment, equipment usage, utilities, repairs and maintenance, safety checks, quality control, consumables and other related O&M activities. Accordingly, the Authority is of the view that ATM growth is an appropriate driver for estimating the escalation in O&M expenses relating to Fuel Farm operations. Therefore, for the purpose of projecting CGF/Fuel Farm expenses for the Fourth Control Period, the Authority proposes to allow cost escalation over FY 2025-26 actuals based on the year-on-year growth rate in ATMs.

10.2.154 Based on the foregoing, and rationalization of the expense heads and their CGF component, the Authority

proposes to consider the said expenses as per the table below:

Table 300: CGF Expenses proposed to be considered by the Authority for the Fourth Control Period (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total CGF Cost 27.15 30.43 34.19 36.32 38.58 166.66

Consultation Paper No: 02/2026-27 Page 253 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD Digitization Expenses

10.2.155 The Authority took note of GHIAL’s submission regarding Digitization expenses in the MYTP for the Fourth Control Period wherein starting in FY27, Rs. 40 Cr has been projected for each year.

10.2.156 GHIAL vide email dated 22.02.2025, submitted the revised year wise breakup of the digitalization cost as per

the table below:

Table 301: Revised year wise breakup of the digitalization cost as submitted by GHIAL (Rs. In crores) Particulars (Rs Cr) FY27 FY28 FY29 FY30 FY31 Total Digitization Cost 52 52 52 52 52 260

10.2.157 The Authority, in the course of its examination of the operating expenditure projections submitted by GHIAL for the Fourth Control Period, observed that a new line item under the head "Digitization Expenses" has been introduced commencing from FY27, with no corresponding expenditure reflected in the preceding years of the Third Control Period. In view of the materiality of the said projection and the absence of any historical baseline, the Authority sought clarification from GHIAL on the rationale, scope, and justification for the said expenditure.

10.2.158 In response, GHIAL submitted that the Digitization Expenses are envisaged to be incurred from FY27 onwards, and are driven by planned investments in advanced technology platforms, automation, and digital infrastructure.

The stated objectives of the said expenditure, as submitted by the Operator, include:

(i) Improvement in operational efficiency;

(ii) Enhancement of passenger experience;

(iii) Modernization of airport processes;

(iv) Process optimization across functions; and

(v) Compliance with global best practices in airport operations.

10.2.159 GHIAL has further submitted that these cost escalations are aligned with the airport's long-term strategic objectives of positioning RGIA as a technologically advanced and globally benchmarked airport.

10.2.160 The Authority, while taking note of the broad strategic intent articulated by GHIAL, observed that the submission was generic in nature and lacked the requisite granularity to enable a meaningful regulatory assessment. Accordingly, the Authority sought from GHIAL a detailed activity-wise breakdown of the proposed Digitization Expenses, including the specific initiatives, the underlying cost build-up, and the expected outcomes.

10.2.161 In response to the said requisition, GHIAL submitted that the projected expenditure of Rs. 260 crore for the Fourth Control Period has been arrived at on the basis of benchmarking with comparable Indian airports handling passenger traffic in the range of 35-50 MPPA. Specifically, GHIAL has cited the following references:

(i) MIAL: proposed allocation of approximately Rs. 149.10 crore for ICT modernization in the Fourth Control Period;

(ii) BIAL: proposed allocation of approximately Rs. 263.54 crore for modernization initiatives in the Third Control Period.

10.2.162 GHIAL has submitted that, in light of the comparable passenger traffic profile and the planned modernization initiatives at RGIA, a provision of Rs. 260 crore is reasonable. GHIAL has further informed

Consultation Paper No: 02/2026-27 Page 254 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD the Authority that an independent consultant has been engaged to identify the key priority initiatives under this head, and that the activity-wise details would be furnished to the Authority in due course.

10.2.163 GHIAL via email dated 22.03.2026, shared the indicative use cases that would be developed over the next five years as part of the airport digital platform.

10.2.164 While focusing on this, GHIAL submits that it aims to appoint a strategic digital partner through a competitive bidding process who will be responsible for owning, developing, deploying, maintaining, and operating the digital platform that will enable these use cases.

10.2.165 The Authority observes that it is a challenging task to clearly differentiate the costs of Digitization between Aeronautical and Non-Aeronautical services. The Authority notes that GHIAL, in its MYTP submission, had allocated the 100% of the proposed digitalization cost as aeronautical.

10.2.166 The Authority is reaching a conclusion that the allocation of the costs must be based on the utility of the service coverage through the digital platform, the nature of revenues generated through the platform and the passenger feedback rather than employing cost drivers alone.

10.2.167 For the purposes of Aeronautical Allocation of the Digitization Cost, the Authority proposes to implement a Multi-Criteria Decision Analysis (MCDA) approach to allocate the Costs between Aeronautical and Non- Aeronautical.

10.2.168 This MCDA approach employs a list of variables to segregate the costs. Each variable has been assigned a score between 1 to 5, where 1 being the lowest and 5 being the highest. The Aeronautical and Non- Aeronautical Services offered in the App have been grouped into different categories based on the nature / similarity of their functions. Following which, each of the categorizations is assigned a score under each variable based on their function. Each variable and its categorization is detailed below:

i. Different variables have been assigned and segregated into Aeronautical and Non-Aeronautical

Services availed at the Airport using the Digitalization App: a. Necessity (Is it a Necessary Service for an Airport Passenger?) b. Channel Usefulness (Is it an Exclusively Provided Service / Information for an Airport Passenger? And how useful is it for them?) c. Revenue Generating Capacity (Is it a Revenue Generating Service or Not?)

Consultation Paper No: 02/2026-27 Page 260 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD

10.2.169 Each variable has been given a judgmental score between ‘1’ to ‘5’ (‘1’ being the lowest and ‘5’ being the highest).

Table 303: 5-Scale Rating Definitions for Evaluation Criteria Rating Necessity Channel Usefulness Revenue Generating Capacity 5 Critical Highly useful Very High 4 High Useful High 3 Moderate Average Moderate 2 Low Limited Use Low 1 Not necessary Not Useful Negligible/None

10.2.170 The use cases have been classified into different categories (Aeronautical, Non-Aeronautical and Common) based on the kind/variety of services they offer and ranked for each of the variables mentioned above.

10.2.171 Using these scores of Aeronautical and Non-Aeronautical, the allocation percentage is identified as below:

Table 305: Digitization Cost Aeronautical Allocation as proposed by the Authority Total Score’s Total Aeronautical Score (a) 108 Total Non-Aeronautical Score (b) 59 Total Common Score (c) 37 Total (d) = (a) + (b) + (c) 204 Aeronautical Allocation (%) (e = a/(a+b)) 64.67%

10.2.172 Therefore, as seen from the preceding table, the Digitization Cost can be allocated at 64.67% and the Authority is seeking stakeholder response before concluding on this aspect.

10.2.173 Thus, applying this 64.67% only on the proposed Digitization cost payable to the Digital Service Provider,

the cost allocable to Aeronautical services is as below:

10.2.174 The Authority recognises that digital transformation is critical to the next phase of aviation growth, enabling seamless end-to-end passenger services through targeted digital use cases. It acknowledges the importance of emerging technologies in improving operational efficiency, passenger experience, and real- time KPI monitoring. Accordingly, the Authority agrees to accept the related expenditure, subject to prudence checks and supporting documentation, with final true-up to be considered in the next Control Period based on actual costs and demonstrated benefits.

Strategic, Management and Technical Service Fee

10.2.175 The Authority took note of GHIAL’s submission regarding a new expense head, Strategic, Management and Technical Service Fee, proposed for the Fourth Control Period.

10.2.176 The Authority sought clarification from GHIAL on the details and justifications for projection of such expenses for the Fourth Control Period. GHIAL’s responses are as follows: “GHIAL Board in its meeting dated 23.07.2025, has approved the payment of Strategic, Management and Technical Service Fee from FY26 to all its shareholders including GMR Airports Limited (GAL), Airport Authority of India and Government of Telangana. The Clauses 3.4 and 3.5 of the Shareholders Agreement defines the Role of the Sponsors which lists down the various activities that the Sponsors are to provide.

The Clause 5.10 of the Shareholders Agreement provides that all decisions of the Board shall be a simple majority of the Directors present and voting. The Clause 11.3 of the Shareholders Agreement mentions that GHIAL shall provide to each of its investors with a right to consult and advise management of GHIAL on various issues.

Hence the board of GHIAL has now decided to start paying, going forward, a consideration for the services being provided by shareholders to the Company towards its strategic leadership, governance and business sustainability @3% of stand-alone gross revenue from FY 2026 on a quarterly basis.”

10.2.177 The Authority notes that, as per the present shareholding pattern of GHIAL, 26% of the shareholding is held by Government entities, comprising 13% held by AAI on behalf of the Government of India, and 13% held by the Government of Telangana, while the remaining 74% is held by GMR Airports Limited

(GAL). GHIAL has referred to certain provisions of the Shareholders’ Agreement and submitted that the Board of GHIAL has decided to make payments to its shareholders towards services stated to be provided by them in relation to strategic leadership, governance and business sustainability. GHIAL has proposed that such consideration would be paid at the rate of 3% of standalone gross revenue, with effect from FY 2025-26, on a quarterly basis.

10.2.178 The Authority has analysed GHIAL’s submission and observes as under: i. Clauses 3.4 and 3.5 of the Shareholders’ Agreement set out the roles of the Sponsors and the State Promoters in providing support to GHIAL. The activities listed for the State Promoters primarily relate to the initial support required for commencement of airport operations. The activities listed for the Sponsors also relate to commencement of airport operations and include reference to services to be provided in the ordinary course of business for operation, management and development of the airport and for provision of airport services.

Consultation Paper No: 02/2026-27 Page 263 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD ii. The aforesaid clauses are general enabling provisions defining the broad roles and obligations of shareholders in relation to the airport project under the Concession Agreement framework. The Authority does not find any specific provision in the Shareholders’ Agreement which provides for payment of separate consideration to shareholders towards advice, consultation, strategic leadership, governance or business sustainability services.

iii. The Authority is of the view that Hyderabad Airport was awarded to GAL through a transparent competitive bidding process with a clear mandate of development, construction, operation and maintenance of the airport for the concession period. Further, at the time of evaluation of the bids, GAL was shortlisted considering their ability to develop and manage the airport operations.

Considering the Strategic, Management and Technical Service Fee to run the airport operations would defeat the above purpose and will lead to an additional fee being rendered to the shareholders in addition to the return on their invested equity.

10.2.179 The Authority further observes that GHIAL is a separate legal entity having its own senior management, personnel and functional structure for operating, managing and developing the airport. In addition, GHIAL already avails expert services from personnel of group companies and engages consultants/domain experts in various fields in the ordinary course of its business. Therefore, the Authority is of the view that a blanket quarterly payment to shareholders would lead to a risk of overlap between the proposed fees and costs already embedded in GHIAL’s existing expenditure base, including employee costs, administrative expenses, consultancy charges and other management-related expenses and may result in duplication of costs and consequential double recovery from airport users.

10.2.180 Accordingly, the Authority proposes not to consider the payment towards Strategic, Management, and Technical Service Fees to shareholders.

Concession Fee

10.2.181 GHIAL has proposed the following concession fee for the Fourth Control Period Table 307: Concession Fee submitted by GHIAL (Rs. In crores) FY ending March FY27 FY28 FY29 FY30 FY31 Total Concession Fee submitted by GHIAL 176.07 201.33 232.58 259.81 290.27 1,160.06

10.2.184 In view of the above, the Authority proposes to consider Aeronautical Operating Expenses of Rs. 5,156.40 Crores as per Table 309 for the Fourth Control Period as against GHIAL’s submission of Rs. 9,291.37 Crores (as per Table 246).

10.2.185 The Authority observes a substantial variation between the Operating Expenses submitted by the Airport Operator and those proposed by the Authority for the Fourth Control Period. The said variation is attributable to:

(a) Adoption of unaudited actuals as the base figure for projection, in preference to the projected base considered by the Operator;

(b) Rationalisation of specific expense heads, including Manpower Expenses, Bank Charges, Repairs & Maintenance, and General Administrative Expenses; and

(c) Non-consideration of certain expense items, namely Corporate Social Responsibility (CSR), Donation to Electoral Fund, and Strategic Management & Technical Service Fee.

Consultation Paper No: 02/2026-27 Page 265 of 308AERONAUTICAL OPERATION & MAINTENANCE (O&M) EXPENSES FOR THE FOURTH CONTROL PERIOD

10.2.186 Upon examination, the Authority is of the view that the Airport Operator is expected to enhance operational efficiency through optimization of overall Operating Expenses, particularly employee costs and Operations & Maintenance (O&M) expenses, including through leveraging technology and process improvements for cost rationalization.

10.3 Authority’s proposals regarding Aeronautical Operation and Maintenance (O&M) Expenses for the Fourth Control Period Based on the material before it and its examination, the Authority proposes the following with respect to Aeronautical Operation and Maintenance (O&M) Expenses for the Fourth Control Period:

10.3.1 To consider Aeronautical O&M Expenses for the Fourth Control Period as per Table 309.

10.3.2 To true up Aeronautical O&M Expenses for the Fourth Control Period based on actuals at the time of tariff determination for the Fifth Control Period, subject to reasonableness and efficiency.

Consultation Paper No: 02/2026-27 Page 266 of 308NON-AERONAUTICAL REVENUE FOR THE FOURTH CONTROL PERIOD 11 NON-AERONAUTICAL REVENUE FOR THE FOURTH CONTROL PERIOD

11.1 GHIAL’s submissions regarding Non-Aeronautical Revenue for the Fourth Control Period

11.1.1 GHIAL has forecasted the Non-Aeronautical Revenues for the Fourth Control Period based on the

following key growth drivers: • ATM growth rate • Total passenger traffic growth rate • International passenger traffic growth rate • Cargo volume growth rate • Contractual (Rentals, Common Area Maintenance etc.) and • CPI Increase • Fully Operated 34 MMPA Terminal throughout from FY 2026 to FY 2031 • Northern Precinct Terminal to be operated from 01.10.2029

11.1.2 The key drivers for different non-aeronautical revenue streams as submitted by GHIAL is given in the

below table:

Table 310: Growth Drivers for Non-Aero Revenue projections submitted by GHIAL as per MYTP International Cargo ATM Growth Passenger Passenger throughput linked revenue Growth linked Others Growth linked growth linked streams revenue streams revenue streams revenue streams ➢ Revenue share ➢ Rental Income ➢ Fuel Farm from In-flight ➢ Revenue share ➢ Revenue from revenues kitchen from Duty Free ➢ Revenue Share Advertisement ➢ Revenue share ➢ Retail & F&B ➢ Public from Cargo ➢ Other from ground revenues Admission Fee Miscellaneous handling ➢ Plaza Lounge ➢ Forex income ➢ Car Parking

11.1.3 Further, GHIAL in its submission acknowledged that the revenues from Cargo, Ground Handling & Fuel Farm have been treated as non-aeronautical in nature. Also, the Profit Before Tax (PBT) of non- aeronautical revenues has been considered for cross subsidization purpose by GHIAL.

11.1.4 Projections of the different non-aeronautical revenues streams as per GHIAL’s submission are summarized

below:

Table 311: Basis of projection for NAR as adopted by GHIAL for the Fourth Control Period S Revenue Growth Basis of Projection No Stream Driver GHIAL has considered fuel farm revenues as non-aeronautical in nature 1 Fuel Farm ATM Growth and charges fuel infrastructure charge of Rs 1500/KL as per the GHIAL 3rd Control Period order.

Consultation Paper No: 02/2026-27 Page 267 of 308NON-AERONAUTICAL REVENUE FOR THE FOURTH CONTROL PERIOD S Revenue Growth Basis of Projection No Stream Driver The revenue that accrues to GHIAL from Ground Handling – Registered Ground 2 ATM Growth Parties is directly proportional to the ATMs handled. Hence, GHIAL has Handling considered the revenue growth linked to the overall growth of ATMs.

GHIAL expects to continue the existing charge of USD 1.25 per UDF billable passenger for the 4th Control Period. GHIAL receives revenue 3 ICT PAX Growth share of 3% on the ICT charges which is projected to increase through passenger growth.

GHIAL has considered overall passenger growth for projecting the In- In-Flight flight Kitchen revenues along with a yearly inflationary increase (CPI at 4 PAX Growth Kitchen 4.2%). For flight kitchen rentals, GHIAL has considered rental growth of 5% on yearly basis.

GHIAL in its MYTP submission has stated that the performance of F&B, Food & Retail and Lounge concessionaries are directly linked to the passenger Beverages, 5 PAX Growth growth. Hence, GHIAL has considered the passenger growth rates for Retail and projecting the revenue share from the concessionaries for the 4th Control Lounge income Period Car Parking & GHIAL has projected revenues from Car Park and Radio Taxi based on 6 PAX Growth Radio Taxi passenger traffic growth rate during the 4th Control Period.

Duty Free operations have been concessioned out for setting up, developing, operating, maintaining, and managing the duty-free outlet at International RGI Airport. GHIAL has submitted that Duty Free performance is linked 7 Duty Free Passenger to international passenger growth and has accordingly projected Duty Free Growth revenue using the international passenger growth rate.

For Duty Free rentals, GHIAL has applied a yearly contractual rental growth of 5%.

International GHIAL has considered the projected Public Admission Fee revenue of FY Public 8 Passenger 2026 as the base year, with subsequent years projected on the basis of Admission Fee Growth international passenger growth.

GHIAL has submitted that, due to the increasing adoption of credit cards International and the proposed extension of UPI to foreign nationals, no growth is 9 Forex Passenger anticipated in Forex revenues. Accordingly, GHIAL has projected Forex Growth revenue to remain constant at FY 2025 levels throughout the Fourth Control Period.

GHIAL has granted a concession to GMR Air Cargo and Aerospace Engineering Limited (GACAEL). A second cargo operator has also been onboarded, with operations expected to commence during FY 2026 at a revenue share of 26%. GHIAL has assumed the cargo volume to be shared Cargo 10 Cargo between the two operators in the ratio of 80:20, resulting in a blended Throughput revenue share of 19.6%, which has been applied to projected cargo volumes. Further, rental income from the Cargo Terminals has been projected with a contractual increase of 5% per annum during the Fourth Control Period

Consultation Paper No: 02/2026-27 Page 268 of 308NON-AERONAUTICAL REVENUE FOR THE FOURTH CONTROL PERIOD S Revenue Growth Basis of Projection No Stream Driver GHIAL has reached its saturation in land & space across the terminal.

Thus, GHIAL has considered only contractual increase of 5% for every year. Further increase in rental area in FY 30 & FY 31 is considered on account of Northern Precinct Expansion. The increase has been considered

as below:

11 Rental Income Others For FY2030, increase in rentals is calculated for 3 months of the entire year. The factor used is 50% of the proportion of increase in Northern precinct terminal area to the total expanded terminal area.

For FY2031, increase in rentals is calculated for the entire year. The factor used is 67% ( i.e., 2/3rd) of the proportion of increase in Northern precinct terminal area to the total expanded terminal area.

GHIAL has concessioned out advertising rights at RGI Airport to Laqshya Hyderabad Airport Media Pvt Ltd (LHAMPL). LHAMPL provides advertising space within the terminal as well as in the broader airport area.

GHIAL has noted that the conventional brick-and-mortar advertisement business is increasingly facing competition from digital advertisement, 12 Advertisement Others with corporate spending shifting towards digital platforms. Further, in light of the broader economic slowdown and cost rationalization measures by businesses, advertisement and promotion budgets have come under pressure. Considering these factors, GHIAL has projected advertisement revenues for the Fourth Control Period based solely on the overall passenger growth rate.

Miscellaneous Income includes revenues from Airport Entry Passes (AEP), Other IT, permits, airline security, filming and paid porters. As these are ancillary 13 Miscellaneous Others revenues and are not contractual in nature, the revenue under this head is Income proposed to remain constant at FY2025 levels for the 4th Control Period.

11.1.5 Based on the above approach, GHIAL has projected the Non-Aeronautical Revenue for the Fourth Control

Period as per the table below:

11.2 Authority’s examination regarding Non-Aeronautical Revenue for the Fourth Control Period

11.2.1 The Authority analyzed the trend of the Non-Aeronautical Revenues over the past two Control Periods as

per AERA principles which is given below:

11.2.2 The Authority also compared the actual revenues vis-a-vis revenues projected by GHIAL at the time of

tariff determination for the past two Control Periods based on AERA principles which is given below:

Comparision of Projected and Actual NAR in Rs. Crs 1000 900 800 700 600 500 400 300 200 100 0 FY17 FY18 FY19 FY20 FY21 FY22 FY23 FY24 FY25 FY26 GHIAL Projection Actual NAR Figure 11: Comparison of Projected and Actual Non-Aeronautical Revenue

11.2.3 The Authority has examined the trend of the actual Non-Aeronautical Revenues (NAR) generated by GHIAL vis-à-vis the corresponding projections submitted by GHIAL in the Multi-Year Tariff Proposal

(MYTP), over the period FY 2016-17 to FY 2025-26, viz., encompassing both the Second Control Period and the Third Control Period. The comparative position is depicted in the chart hereinabove.

11.2.4 The Authority notes that the actual NAR has consistently surpassed the corresponding projections submitted by GHIAL in the MYTP across nearly all years of the said period, save for FY 2020-21 and FY 2021-22, where the actuals were broadly in line with, or marginally below the projections, the said deviation being

Consultation Paper No: 02/2026-27 Page 271 of 308NON-AERONAUTICAL REVENUE FOR THE FOURTH CONTROL PERIOD squarely attributable to the disruption caused by the COVID-19 pandemic and the consequent moderation in passenger throughput and concessionaire activity.

11.2.5 This was then compared to the revenue trends projected by GHIAL (considering revenue heads as per AERA) for the Fourth Control Period, as detailed below:

NAR projection by GHIAL for the 2nd, 3rd and 4th Control Period in Rs. Crs 1400 1200 1000 800 600 400 200 0 FY17 FY18 FY19 FY20 FY21 FY22 FY23 FY24 FY25 FY26 FY27 FY28 FY29 FY30 FY31 Figure 12: Category wise Non-Aeronautical Revenue for the Second, Third and Fourth Control Period

11.2.6 While optically, the trend of the amounts projected for the Fourth Control Period are in line with the trend in the Second and the Third Control Period, the Authority further delved into detailed analysis taking into consideration the CAGR for each of the two Control Periods. CAGR computed for the Second, Third and the Fourth Control Period (under consideration) as per Authority principles is provided below:

Table 313: CAGR for the Second and the Third Control Periods based on actuals and for the Fourth Control Period based on NAR as proposed by GHIAL CAGR for 4th CP Particulars CAGR for 2nd CP CAGR for 3rd CP (under consideration) Passenger Linked Revenue 15.47% (FY17- FY20) 17.28% (FY23-FY26) 9.78% Other Non-Aeronautical

4.80% (FY17-FY20) 9.03% (FY23-FY26) 10.87% Revenue

11.2.7 The Authority notes that the high CAGR for Third Control Period (FY 23-FY26) was on account of the delayed revenue recovery post Covid.

11.2.8 The Authority notes from the above table that the growth trends in Non-Aeronautical Revenue across the Second Control Period, Third Control Period and the Fourth Control Period projections do not exhibit a uniform or consistent CAGR pattern. While Passenger Linked Revenue has shown relatively higher growth during the Second and Third Control Periods, the CAGR proposed for the Fourth Control Period is comparatively lower. Conversely, Other Non-Aeronautical Revenue reflects a lower CAGR during the

Consultation Paper No: 02/2026-27 Page 272 of 308NON-AERONAUTICAL REVENUE FOR THE FOURTH CONTROL PERIOD Second Control Period, an increase during the Third Control Period, and a further increase in the Fourth Control Period projections.

11.2.9 In view of the varying growth trends across different components of Non-Aeronautical Revenue, the Authority considers it appropriate to undertake a more granular, head-wise examination of the Non- Aeronautical Revenue proposed by GHIAL for the Fourth Control Period, taking into account the nature of each revenue stream, its linkage with passenger traffic or other operating parameters, historical performance, contractual arrangements, and other relevant business drivers.

11.2.10 The Authority after examination of GHIAL’s submission of inflation rate for projecting Non-Aeronautical Revenue under certain heads for the Fourth Control Period proposes to consider inflation rate (WPI) (as per Table 240) for the Fourth Control Period as per the “Results of the Survey of Professional Forecasters on Macroeconomic Indicators – Round 99” published by the RBI.

11.2.11 A summary of the head wise proposals of the Authority in comparison with the basis of projection as

adopted by GHIAL is provided below:

Consultation Paper No: 02/2026-27 Page 274 of 308NON-AERONAUTICAL REVENUE FOR THE FOURTH CONTROL PERIOD measures by businesses, advertisement and promotion budgets have come under pressure.

Considering these factors, GHIAL has projected advertisement revenues for the Fourth Control Period based solely on the overall passenger growth rate.

Miscellaneous Income includes revenues from Airport Entry Passes (AEP), IT, permits, airline Other security, filming and paid porters. As these are The Authority proposes to use the inflation rate 9 Miscellaneous ancillary revenues and are not contractual in as annual escalation rates as the growth driver Income nature, the revenue under this head is proposed for all the years.

to remain constant at FY2025 levels for the 4th Control Period.

11.2.12 The Authority further notes that no income has been projected under the head “Other Income (interest and dividend income)” and has examined the same.

Other Income2

11.2.13 The Authority notes that Other Income primarily comprises of Interest Income on Bank deposits and Dividend income.

Interest Income

11.2.14 The Authority has examined the position in relation to the Cash and Bank Balance available with GHIAL for the purpose of determining whether any Excess Cash is available with GHIAL, the income from which would otherwise have been required to be considered as a deduction from the Aggregate Revenue Requirement for the Fourth Control Period. In this regard, the Authority observes that:

a. the Cash and Bank Balance available with GHIAL as on 31 March 2026, as per the unaudited financial statements of GHIAL, stands at ₹114.05 Crore; and b. GHIAL has, in its MYTP submission, proposed Capital Expenditure aggregating to ₹15,377.62 Crore (inclusive of Interest During Construction (IDC)) for the Fourth Control Period.

11.2.15 The Authority is of the considered view that, given the substantial capital expenditure proposed to be undertaken by GHIAL during the Fourth Control Period for which the Cash and Bank Balance available will be required to be deployed (whether towards direct funding of capital expenditure or towards bridging working capital requirements during the construction phase) there would be no Excess Cash available with GHIAL during the Fourth Control Period that could be deployed to generate investment income.

Accordingly, the Authority, proposes to True up the actual revenue accrued on account of interest income at the time of tariff determination for the Fifth Control Period.

Dividend Income 2 (incl. interest income, dividend income, profit on sale of investments, provisions no longer written back, other non- operating income etc.)

Consultation Paper No: 02/2026-27 Page 275 of 308NON-AERONAUTICAL REVENUE FOR THE FOURTH CONTROL PERIOD

11.2.16 The Authority notes that GHIAL has accounted for dividend income of Rs. 14.57 Crores in its books of accounts for FY 2025-26. Consistent with the approach adopted by the Authority during tariff determination for the Third Control Period, the Authority proposes to consider the actual dividend income for FY 2025-26 as the base for projecting dividend income for the Fourth Control Period. The Authority further proposes that the dividend income considered for the Fourth Control Period.

Revenue from CGF, ICT

11.2.17 The Authority notes that GHIAL has treated revenue from Cargo, Ground Handling, Fuel Farm and ICT services as Non-Aeronautical Revenue. The Authority has examined the matter and is of the view that revenues from Cargo, Ground Handling and Fuel-related services are in the nature of Aeronautical Revenue as per Section 2(a) of the AERA Act, 2008. Further, ICT services, including CUTE, CUSS, BRS and related IT services, are integral to airport operations and facilitate the provision of aeronautical services. Therefore, in line with provisions of AERA Act and the consistent regulatory treatment adopted by the Authority from the First Control Period onwards, the Authority has considered revenues from Cargo, Ground Handling, Fuel Farm and ICT services as Aeronautical Revenue and has excluded the same from the computation of Non-Aeronautical Revenue.

Real Estate Income

11.2.18 As mentioned in Para 1.6.1, 1.6.2, 1.6.3, 1.7.1, 1.7.2, 1.7.3, 1.7.4 and 1.7.5 of this Consultation Paper, with regard to the issues raised by the Authority in the Civil Appeal against the judgements of the Hon’ble TDSAT, the Authority is of the view that presently it needs to continue the tariff determination exercise in line with the decisions taken in the Tariff Order for the Third Control Period as the matter is sub-judice before the Hon’ble Supreme Court. And accordingly proposes treat revenue from real estate development as non-aeronautical in nature.

11.2.19 Based on the above, the Authority proposes to consider the Non-Aeronautical Revenue for the Fourth

Control Period as per the table below:

11.3 Authority’s proposals regarding Non-Aeronautical Revenue for the Fourth Control Period Based on the material before it and its examination, the Authority proposes the following with respect to Non-Aeronautical Revenue for the Fourth Control Period:

11.3.1 To consider Non-Aeronautical Revenues for RGIA in accordance with Table 315.

11.3.2 To True up NAR for the current control period, at the time of determination of tariff for the next control period, subject to the minimum threshold as proposed by the Authority in Table 315.

Consultation Paper No: 02/2026-27 Page 277 of 308AERONAUTICAL TAXES FOR THE FOURTH CONTROL PERIOD 12 AERONAUTICAL TAXES FOR THE FOURTH CONTROL PERIOD

12.1 GHIAL’s submission regarding Aeronautical Taxes for the Fourth Control Period

12.1.1 GHIAL in the MYTP has computed the building block ‘T’ towards taxes pertaining to regulated charges for the Fourth Control Period. GHIAL has computed the same based on Aeronautical Revenue, 30% of non-aeronautical revenue, Operation and Maintenance Expenditure, Concession Fee, Aeronautical Depreciation and Aeronautical Interest expenses.

12.1.2 GHIAL has submitted that the Aeronautical Interest expenses have been computed as Approved RAB multiplied by approved / eligible debt gearing and approved cost of debt. GHIAL has further considered accumulated losses while computing the earning on which normal tax is calculated.

12.1.3 The Aeronautical Taxes submitted by GHIAL for the Fourth Control Period are shown in the table below:

12.2 Authority’s examination regarding Aeronautical Taxes for the Fourth Control Period

12.2.1 The Authority observes that GHIAL has considered 30% NAR in the estimation of aeronautical profit before tax (PBT), The fact that a part of NAR is used for cross-subsidization as per the hybrid till mechanism does not change nature of such revenue to aeronautical. Further, the cross subsidization as per the hybrid till mechanism is done to reduce tariff pressure on passenger and incentivize GHIAL to make effective investments in non-aeronautical income generating sources.

12.2.2 The Authority notes that GHIAL has considered opening accumulated losses of Rs. -394.03 Crores in FY 2026-27 and has set off the same against the earnings pertaining to regulated charges in FY 2026-27, while computing the earning on which normal tax is calculated.

Consultation Paper No: 02/2026-27 Page 278 of 308AERONAUTICAL TAXES FOR THE FOURTH CONTROL PERIOD

12.2.3 GHIAL has computed the interest expenses considering that 48% of the average RAB is financed through debt. However, it is observed that, in actuality, 70% of the average RAB has been financed through debt.

Accordingly, the interest expenses have been reworked by considering debt financing at 70% of the average RAB.

12.2.4 The Authority has relied upon the judgement of Hon'ble Supreme Court dated 11.07.2022 and worked out corporate tax based on regulatory accounts/regulatory building block. The Authority notes that Aeronautical Taxes are to be computed only on earnings pertaining to regulated charges after adjustment of accumulated losses. In case accumulated losses are available, the same are to be set off against the earnings pertaining to regulated charges before computing the tax liability.

12.2.5 Based on the above, the Aeronautical Taxes for the Fourth Control Period proposed to be considered by

the Authority are shown in the table below:

13.2.5 The Authority also notes the methodology carried out by ACI for arriving at the ASQ ratings for Airports

as follows: i. ACI ASQ is a quarterly benchmarking programme measuring passenger’s satisfaction and experience about an Airport with participation from around 350-400 airports across the world.

Consultation Paper No: 02/2026-27 Page 280 of 308QUALITY OF SERVICE FOR THE FOURTH CONTROL PERIOD ii. The passenger experience is measured based on passenger emotions and their impact to arrive at Emotional Score.

iii. The passenger satisfaction is measured based on various service quality parameters as mentioned

below: a. Arrival at the airport (Ease of getting to the Airport, Signage to access terminal and parking facilities) b. Check-in (Ease of finding check-in area, waiting time at check-in, courtesy and helpfulness of staff) c. Security screening (Ease of going through security screening, waiting time at the security screening and courtesy and helpfulness of security screening staff) d. Border/passport control (Waiting time at Border/passport control and courtesy and helpfulness of staff) e.

14.2.4 The Authority based on its examination has proposed an Aggregate Revenue Requirement of Rs. 13,221.10 Cr (Rs. 10,118.57 Cr. in PV terms) against an Aggregate Revenue Requirement of 27,851 Cr (Rs. 20,025 Cr. in PV terms) as submitted by GHIAL. The major reasons for the variance between GHIAL’s submission and Authority’s proposals are as below:

Consultation Paper No: 02/2026-27 Page 284 of 308AGGREGATE REVENUE REQUIREMENT FOR THE FOURTH CONTROL PERIOD • Consideration of Under recovery to be trued up from the Third Control Period of Rs.319.80 Cr against GHIAL’s submission of Under recovery of Rs. 5,528.41 Cr for the same period. Difference is mainly due to non consideration of the impact of TDSAT judgement.

• Rationalization of Capital Expenditure and O&M Expenses for the Fourth Control Period by the Authority vis-a-vis the submission made by GHIAL. • Revision in Non-Aeronautical Revenue for the Fourth Control Period based on realistic growth rates vis a vis the growth rates as considered by GHIAL.

14.3 Incremental ARR Approach on User Pay Principle for identified High-Capex Projects

14.3.1 It can be seen from the above table that in the financial year 2029-30, the capital addition of Northern Passenger Terminal Building of 20 MPPA and related infrastructure with aero capex of Rs. 5,328.45 Crore and Northern Precinct airside works comprising of new Runway, Taxiways, Aprons and other airside related works with capex of Rs. 4,585.49 Crore is taking place together accounting for almost 79% of the overall capital additions for the fourth control period which is significantly impacting the return on RAB & Depreciation. These capital assets are getting capitalised and shall be put to use in 2029-30, whereas their impact is getting applied on the passenger travelling in the 1st year of the Control Period. This is not in consonance with the fundamental principle of Airport Charges that user pays for the facilities and services that are available for use. Further, in this context it is pertinent to mention that: -

(i) Principles embodied in the International Civil Aviation Organization (ICAO) Policies on Charges for Airports and Air Navigation Services recognize that users should ultimately bear their full and fair share of the costs associated with the provision of airport infrastructure and services. Implicit in this principle is the expectation that charges should bear a reasonable relationship to the facilities and services made available to users. Where users are required to pay enhanced charges significantly in advance of the creation and operationalization of such facilities, concerns may arise regarding inter-generational equity, cost causation, and the alignment between charges and service delivery.

(ii) The regulatory procedure that allows recovery of return on RAB, depreciation, and associated costs based solely on projected capitalization may not sufficiently incentivize timely execution and commissioning of capital projects. Where tariff recovery is substantially assured irrespective of actual project completion timelines, there may be limited regulatory impetus for ensuring adherence to committed implementation schedules. The Authority has actually observed that, in several past instances, major capital expenditure projects projected for commissioning within a Control Period are subsequently delayed, rescheduled, phased differently, or, in certain instances, not executed at all. Such deviations between projected and actual capitalisation can lead to a mismatch between tariff recovery and asset availability. As a result, airport users may bear charges based on investments that have not yet materialised, while the Airport Operator may receive revenue recovery in advance of the corresponding asset being put into use. Such an outcome may not be consistent with the broader objectives of efficiency, accountability, and performance-based regulation.

14.3.2 In the light of the foregoing considerations, the Authority is of the view that in cases where large and significant capex items are part of the 5 year capex plan and these capex having significant impact on aeronautical tariffs are expected to be commissioned during the latter part of the Control Period, particularly

Consultation Paper No: 02/2026-27 Page 285 of 308AGGREGATE REVENUE REQUIREMENT FOR THE FOURTH CONTROL PERIOD during the last two years of the Control Period then it is most appropriate that these capex items be put under the ‘user pay principle’ and factored in the regulatory framework from the expected date of its capitalisation in the later part of the Control Period so that the burden of these big ticket capital items is not borne from the beginning of the 5 year Control Period by the passengers & airlines and other airport users even when these capital items are yet to capitalise and made available for users.

14.3.3 Accordingly, the Authority proposes to adopt, on a project-specific basis, an Incremental ARR Approach on user pay principle for identified high-capex projects. Under this approach, the base ARR and corresponding aeronautical tariffs for a Control Period shall be determined excluding the impact of specified future capital projects. Simultaneously, the Authority for ensuring regulatory certainty and encouraging timely completion of planned capital projects of airport shall determine, ex ante, the incremental ARR and YPP impact of each identified project based on prudently assessed project costs, financing assumptions & scheduling assumptions, and incremental ARR shall be given effect through revised aeronautical tariffs as and when each identified project is capitalised and put to operational use.

14.3.4 The Authority considers that such an approach would provide multiple regulatory benefits. First, it would ensure closer alignment between tariff recovery and the actual availability of airport infrastructure and services. Second, it would protect airport users from premature tariff burdens arising from assets that are yet to be commissioned. Third, it would strengthen incentives for timely execution and commissioning of capital projects by linking revenue recovery more directly to project delivery. Fourth, it would reduce the risk of over-recovery associated with delays, deferments, or non-execution of forecast capital expenditure.

Finally, it would continue to preserve the Airport Operator's legitimate right to recover prudently incurred investment costs and earn a reasonable return on capital once the relevant assets are brought into service.

14.4 Proposed Methodology

14.4.1 The methodology for the incremental ARR Approach on user pay principle for identified high-capex

projects shall be as follows:

(a) Identification of Eligible High-Value Capital Expenditure Projects

14.4.2 The Authority, based on the facts and circumstances of each case, shall identify the list of eligible projects and their approved capital costs as part of the tariff determination order.

(b) Exclusion of Project-Specific ARR Components for Determination of Base ARR

14.4.3 For each project identified under the Incremental ARR Approach, the Authority shall determine the projected Aggregate Revenue Requirement (ARR) attributable to such project. The project-specific ARR may include, inter alia:

(i) Return on the associated Regulated Asset Base (RAB);

(ii) Depreciation on the capitalized asset;

(iii) Any other component considered appropriate by the Authority.

14.4.4 The Authority shall calculate the ARR and corresponding Yield Per Passenger (YPP) attributable to each identified project based on the approved project cost, financing assumptions, capitalization schedule, and other regulatory parameters applicable for the relevant Control Period.

14.4.5 Thereafter, the ARR and YPP associated with such identified projects shall be excluded from the overall projected ARR for the purpose of determining the Base ARR and Base Yield applicable at the commencement of the Control Period.

Consultation Paper No: 02/2026-27 Page 286 of 308AGGREGATE REVENUE REQUIREMENT FOR THE FOURTH CONTROL PERIOD

14.4.6 The Base ARR shall therefore represent the revenue requirement associated with existing assets and capital projects that are not subject to the Incremental ARR framework, thereby ensuring that airport users are not required to bear tariff increases in anticipation of infrastructure that is yet to be commissioned and made available for operational use.

(c) Determination of Aeronautical Charges Based on Base ARR

14.4.7 The Authority shall determine the aeronautical tariffs applicable at the commencement of the Control Period based on the approved Base ARR and corresponding Base Yield.

14.4.8 The tariffs determined on this basis shall remain applicable unless and until additional ARR associated with identified high-value capital expenditure projects becomes eligible for recovery in accordance with the mechanism specified by the Authority.

14.4.9 This approach seeks to establish a tariff structure that reflects only those assets and services that are available, or reasonably expected to be available, to users during the relevant tariff period, thereby promoting tariff stability and fairness.

(d) Intimation of Project Completion and Put-to-Use by Airport Operator

14.4.10 For the purpose of operationalizing the Incremental ARR framework, the Airport Operator shall be required to formally intimate the Authority regarding the completion and commencement of operational use of any project identified under this mechanism.

14.4.11 To facilitate orderly regulatory review and implementation, and to bring predictability to the review process, the Authority proposes to establish two reporting windows during each financial year:

Window I: Projects completed and put to use during the period from 1st April to 30th September.

Window II: Projects completed and put to use during the period from 1st October to 31st March.

14.4.12 The Airport Operator shall submit the requisite intimation, together with supporting documentation and certifications as may be prescribed by the Authority, within one month from the closure of the relevant reporting window.

14.4.13 For example, where an identified project is completed and put to use at any time during the period from April 2029 to September 2029, the Airport Operator shall submit the relevant intimation and supporting documents by October 2029.

14.4.14 The Authority may prescribe the format, evidentiary requirements, certification standards, and other procedural requirements necessary for establishing that the relevant asset has been completed, capitalized, and put to operational use.

(e) Determination of Incremental Aeronautical Charges Upon Commissioning

14.4.15 Upon receipt of the Airport Operator's intimation, the Authority shall undertake an examination of the submitted information to verify compliance with the conditions specified under the tariff order and to confirm that the relevant asset has been completed, capitalized, and put to operational use.

14.4.16 Following such examination, the Authority will issue an appropriate order providing for recovery of the pre-approved incremental ARR and corresponding YPP associated with the identified project. The order will also specify the resulting revision in aeronautical tariffs and the effective date from which such revised tariffs shall become applicable.

Consultation Paper No: 02/2026-27 Page 287 of 308AGGREGATE REVENUE REQUIREMENT FOR THE FOURTH CONTROL PERIOD

14.4.17 By way of illustration, where an Airport Operator submits an intimation in October 2029 in respect of a project completed and put to use during the April–September 2029 reporting window, the Authority, after completing the necessary evaluation, issue an order enabling the revised aeronautical tariffs to become effective from 1st January 2030.

14.4.18 The Authority clarifies that the purpose of this exercise shall be limited to operationalization of the pre- approved incremental ARR framework and verification of commissioning and put-to-use conditions.

Accordingly, no re-assessment of project costs, financing assumptions, regulatory building blocks, or other cost parameters shall ordinarily be undertaken at this stage.

14.4.19 Any variation between approved and actual project costs, capitalization values, financing costs, operational expenditure, or other relevant parameters shall be examined separately during the True-Up process in accordance with the applicable regulatory framework. The True-Up exercise shall remain the appropriate mechanism for determining the prudence and admissibility of actual costs and for addressing any consequential under-recovery or over-recovery arising from such variations.

Expected Regulatory Outcomes

14.4.20 The Authority is of the view that the proposed framework would:

(a) align tariff recovery more closely with the actual availability of airport infrastructure and services;

(b) protect airport users from premature tariff increases relating to assets that are not yet operational;

(c) strengthen incentives for timely project execution and commissioning;

(d) reduce the likelihood of over-recovery arising from project delays, deferments, or non-execution; and

(e) preserve the Airport Operator's entitlement to recover prudently incurred costs and earn a reasonable return on investment upon commencement of service delivery.

14.4.21 In the light of the above, for the Rajiv Gandhi International Airport, Hyderabad, the capex items identified for incremental ARR approach on user pay principle are –

(i) Northern Passenger Terminal Building of 20 MPPA and related infrastructure - Rs. 5,328.45 crore

(ii) Airside works for Northern Precinct comprising of new Runway, Taxiway, Aprons and related works with capex of Rs. 4,585.49 Crore

14.4.22 These capex items have been identified in view of the fact that they involve substantial capital investment (forming almost 79% of the total Capital additions for the fourth control period) and are expected to be commissioned during fourth year of the control period.
