NOTICE OF 2025 ANNUAL GENERAL MEETING OF SHAREHOLDERS

Notice is hereby given that the fourth annual general meeting (the “Annual General Meeting” or “AGM”) of ReNew Energy Global Plc (the “Company”) will be held at 02:00 p.m. (British Summer Time) on Thursday, September 18, 2025 at St. James’ Court, the Taj, 54 Buckingham Gate, London, SW1E 6AF, United Kingdom.

EXPLANATORY NOTES

The explanatory notes that follow form part of the notice of this AGM and provide important information regarding the items of business to be considered at the AGM. Resolutions 1 to 11 (inclusive) are proposed as ordinary resolutions. This means that for each of these resolutions to be passed, more than half the votes cast must be in favour of the resolution.

Resolution 1 (Companies Act annual reports and accounts)

The Board is required to lay its annual reports and accounts before a general meeting each year. The ‘2025 Annual Reports and Accounts’ comprise the Company’s directors’ report, strategic report, directors’ remuneration report, remuneration policy and annual accounts and auditor’s report for the financial year ended March 31, 2025, prepared in accordance with the Companies Act. The 2025 Annual Reports and Accounts were considered and approved unanimously by the Board on August 13, 2025.

This is the Company's routine submission of the Annual Reports and Accounts for the year ended March 31, 2025.

Resolution 2 (Directors’ remuneration report)

The Directors’ remuneration report sets out the pay and benefits received by each of the directors in respect of the financial year ended March 31, 2025, prepared in accordance with the Companies Act. The Company is required to seek shareholders’ approval of this report. The directors’ remuneration report can be found on pages 84 to 99 of the 2025 Annual Reports and Accounts. The remuneration report, which was based on the recommendations of the Remuneration Committee, was considered and approved unanimously by the Board on August 13, 2025.

The Resolution 2 is an advisory vote to approve the Directors’ Remuneration Report for the year ended March 31, 2025.

Resolution 3 (Directors’ remuneration policy)

The purpose of this resolution is to seek shareholder approval of the Company’s second directors’ remuneration policy (“2025 Policy”) set out on pages 100 to 111 of the 2025 Annual Reports and Accounts.

The first directors’ remuneration policy (the “2022 Policy”) was approved by the shareholders of the Company at the 2022 annual general meeting and was valid for three years. As the 2022 Policy will therefore expire at this AGM, the Company is required to seek shareholder approval for the 2025 Policy. The Board in its meeting held on August 13, 2025 unanimously approved the 2025 Policy in accordance with the recommendations of the Remuneration Committee.

The 2025 Policy sets out how the Company proposes to pay its directors, including every element of remuneration to which a director may be entitled, as well as how the 2025 Policy supports the Company’s long-term strategy and performance. It also includes details of the Company’s approach to recruitment and payments for loss of office.

If the 2025 Policy is approved, the Company will only be permitted to make remuneration payments and payments for loss of office to directors if they are consistent with the 2025 Policy or have been specifically approved by a shareholder resolution. The Company will not be permitted to make any such payments after the end of its current financial year without approval by a specific shareholder resolution if no remuneration policy has been approved.

If approved by shareholders, the 2025 Policy will apply for a three-year term from the conclusion of this AGM, unless it is replaced by a new remuneration policy approved by shareholders at a general meeting. After three years, a new remuneration policy must be proposed to shareholders.

Resolutions 4 to 9 (Approval of directors’ re-appointment)

All six Non-Executive Independent Directors were appointed / re-appointed (appointed Ms. Paula Gold-Williams, Ms. Nicoletta Giadrossi and Mr. Philip Graham New and re-appointed Mr. Manoj Singh, Sir Sumantra Chakrabarti and Ms. Vanitha Narayanan) with effect from August 23, 2023 and the same was approved by the Company’s shareholders at the 2023 annual general meeting of the Company. The respective term of office for each appointee will last until this AGM.

In anticipation of the expiry of their current tenure, the Board has considered the performance and qualifications of each director seeking confirmation of their re-appointment and determined that each of them contributes effectively

and demonstrates commitment to their role. The skills and experience of each director, as summarized in their biographies set out herein after, demonstrate why their contribution is important and how the contribution, commitment and performance they make continue to be important to the Company’s long-term sustainable success.

On July 29, 2025 the Board, on the recommendation of the Nomination and Board Governance Committee, unanimously approved the re-appointment of Mr. Manoj Singh, Sir Sumantra Chakrabarti, Ms. Vanitha Narayanan, Ms. Paula Gold-Williams, Mr. Philip Graham New and Ms. Nicoletta Giadrossi for a period of approximately two years from this AGM up to the annual general meeting of the Company scheduled to be held in the calendar year 2027. The terms of re-appointment of these directors are materially the same as their current terms, including the requirement for approval by the shareholders at this AGM following their appointment by the Board.

If any of these resolutions is not passed, the relevant director’s re-appointment will be terminated immediately from the conclusion of this AGM, in accordance with the terms of his or her appointment/ re-appointment.

Brief biographical details of each of the directors to which the resolutions relate are set out set out on pages 3 to 5 of this document.

Resolution 10 (Re-appointment of auditor)

The current appointment of KNAV Limited (“KNAV”) as Auditor of the Company will terminate at the conclusion of this year’s AGM. KNAV has expressed its willingness to continue in office. The Audit Committee and the Board have unanimously recommended that KNAV be re-appointed until the conclusion of the next general meeting of the Company at which the Company’s annual accounts and reports are laid.

Resolution 11 (Auditor’s remuneration)

The directors may set the remuneration of the auditor if authorized to do so by the shareholders. The Board has recommended that the Audit Committee be authorized to determine the remuneration of KNAV. This resolution seeks authority for the Board and the Audit Committee severally to set the remuneration of the Auditor for the financial year 2025-26.

FURTHER NOTES

     1.

     Some of the resolutions are items that are required to be approved by shareholders under the Companies Act and generally do not have an analogous requirement under United States laws and regulations. As such, while these resolutions may be familiar and routine to shareholders accustomed to being shareholders of companies incorporated in England and Wales, other shareholders may be less familiar with these routine resolutions and should review and consider each resolution carefully.


2.	In accordance with the Articles, all resolutions will be taken on a poll. Voting on a poll will mean that all votes attaching to each Voting Share represented in person or by proxy will be counted in the vote.


3.	All resolutions will be proposed as ordinary resolutions. The ordinary resolutions will be passed by a simple majority of the total voting rights of shareholders who vote on them, whether in person or by proxy.

     4.

If, however, shares in the Company within the systems of The Depository Trust Company (“DTC”) are held for you in a stock brokerage account or by a broker, bank or other nominee, you are considered the “beneficial owner” of those shares. Only shareholders of record have the right to attend, speak and (in respect of any Class A Ordinary Share, Class B Ordinary Share or Class D Ordinary Share (together “Voting Shares”)) vote at the AGM.

     5.

     Beneficial owners of Voting Shares as at the Record Date generally have the right to direct their broker or other agent how to vote the Voting Shares in their account and are also invited to attend the Annual General Meeting.

A shareholder of record may appoint more than one proxy in relation to the Annual General Meeting, provided that each proxy is appointed to exercise the rights attached to a different share or shares.

Further details regarding the process to appoint a proxy, voting and the deadlines therefor are set out in the “Voting Process; Appointment and Revocation of Proxies” section below.

If you make no election in respect of a particular resolution, your proxy will not vote on the resolution. In order to be valid, your voting election must be made no later than 02:30 p.m. BST on Tuesday, September 16, 2025.


15.	The appointment of a proxy will not preclude a shareholder of record from attending and voting in person instead of the proxy at the AGM.

Any voting direction submitted to the Company or its agent by you or on your behalf in accordance with these instructions will (unless the Company

If you give no direction in respect of a particular resolution, the proxy will not vote on the resolution (except that your broker may give instructions to the proxy to vote on certain resolutions at the broker’s discretion in accordance with applicable regulations or, if you return a paper voting instruction form, as described on that form).

Following receipt of your instructions, Computershare will instruct its nominee (which is the registered holder of the shares underlying your depositary receipts) to pass on your instructions to the Company’s agent, which will be deemed to constitute the appointment of the Chairman of the AGM (or some other person agreed by the Company and Computershare) as the nominee’s proxy for the AGM in respect of your shares and an instruction to the proxy to vote those shares in accordance with your directions. If you give no direction in respect of a particular resolution, the proxy will not vote on the resolution.
