Dear Sir/Madam,

Sub: Outcome of Board Meeting – Proposal for buyback of equity shares

This has reference to our letter dated September 8, 2025, regarding the captioned subject and in compliace with the Regulation 30 of the Securities and Exchange Board of India (Listing Obligations and Disclosure Requirements) Regulations, 2015, as amended (“LODR Regulations”). The Board of Directors of the Company at their meeting held on September 11, 2025, has considered and approved a proposal to buyback equity shares for an amount of ₹ 18,000 Crore (Rupees Eighteen Thousand Crore only) (“Buyback Size”) at a price of ₹ 1,800/- (Rupees One Thousand Eight Hundred only) per Equity Share (“Buyback Price”), payable in cash, comprising of a purchase of 10,00,00,000 fully paid-up equity shares of the Company of face value of ₹ 5/- each (“Equity Shares”) representing up to 2.41% of the total number of Equity Shares in the existing total paid-up Equity Share capital of the Company (on a standalone basis), from the equity shareholders of the Company as on a record date to be announced later (“Record Date”). The Buyback Size does not exceed 25% of the aggregate of the paid-up capital and free reserves, based on the latest audited interim condensed standalone and consolidated financial statements of the Company as on June 30, 2025. The buyback is proposed to be made from all equity shareholders of the Company as on the Record Date (including those who become equity shareholders as on the Record Date by cancelling American Depositary Shares (“ADSs”) and withdrawing underlying equity shares) on a proportionate basis through the tender offer route, in accordance with the provisions of the Securities and Exchange Board of India (Buy-Back of Securities) Regulations, 2018 (as amended) (“Buyback Regulations”) and the Companies Act, 2013 and the rules made thereunder (“Buyback”). The Buyback offer is subject to the approval of the shareholders by way of a special resolution through postal ballot by remote e-voting only and all other applicable statutory approvals in accordance with applicable law.

The Buyback Size does not include any expenses or transaction costs incurred or to be incurred for the Buyback, such as, brokerage, filing fees, advisory fees, intermediaries’ fees, public announcement publication expenses, printing and dispatch expenses, applicable taxes such as securities transaction tax, goods and services tax, stamp duty etc. and other incidental and related expenses.

The Board has constituted a buyback committee (the “Buyback Committee”), comprising of Chief Financial Officer, the Chief Legal Officer & Chief Compliance Officer and the Company Secretary of the Company. The Buyback Committee has the power to do all such acts, deeds, matters and things as it may, in its absolute discretion, deem necessary, expedient, usual or proper in connection with the Buyback. Further, The Board has appointed A.G.S. Manikantha, Company Secretary, as the Compliance Officer for the purposes of the proposed Buyback.

The Board also noted that, given the Company’s class of securities registered under Section 12 of the Securities Exchange Act of 1934 in the United States and the shareholding of US residents by way of ADSs and Equity Shares, it is necessary for the Company to seek and obtain exemptive relief from the U.S. Securities and Exchange Commission (“SEC”) on certain aspects of the tender offer procedures, due to conflicting regulatory requirements between Indian and U.S. laws for tender offer buybacks and the Company will be making application in this regard.

The Board noted that consistent with disclosures previously made in the Company’s Form 20-F, the holders of ADSs may be able to participate in the buyback if such ADS holders cancel the ADSs and withdraw the underlying Equity Shares to become equity shareholders of the Company as on the Record Date. Further, such ADS holders will be able to re-deposit against the creation of ADSs any of such Equity Shares that are not tendered in the Buyback, or if tendered, are not accepted in the Buyback. The ADS holders are advised to go through the postal ballot notice, which will be sent out in due course in accordance with the applicable regulations, and relevant SEC filings for further information in regard to conversion of ADSs into Equity Shares and vice versa.

The public announcement and other documents setting out the process, timelines and other statutory details of the Buyback will be released in due course in accordance with the Buyback Regulations.

The pre-Buyback shareholding pattern of the Company as on September 5, 2025 is attached hereto as Annexure A.

The Board Meeting commenced at 8:00 p.m. IST and concluded at 8:40 p.m. IST.

A detailed disclosure as required under Regulation 30 of LODR Regulations read with the SEBI Master Circular No. SEBI/HO/CFD/PoD2/CIR/P/0155 dated November 11, 2024 is enclosed as Annexure B.
