Please monitor the Company’s website (https://investor.renewpower.in/) for any updates, including the latest safety measures in place, should you wish to attend the AGM.

If you do use this facility, you will not be considered to be formally present at the meeting and you will not be able to vote or speak through the facility.

You will find an explanation of each resolution to be proposed at the AGM within the Explanatory Notes on page 4 of this document. The Company’s board of directors (the ‘‘Board’’) considers that all these resolutions are in the best interests of the Company and its shareholders as a whole and are most likely to promote the success of the Company. The Board unanimously recommends that you vote in favor of each of the proposed resolutions, as the members of the Board intend to do in respect of their beneficial holdings (if any).

Notice is hereby given that the first Annual General Meeting (the ‘‘AGM’’) of ReNew Energy Global Plc (the ‘‘Company’’) will be held at 3:00 p.m. (British Summer Time) on Friday, August 19, 2022 at St. James’ Court, the Taj, 54 Buckingham Gate, London, SW1E 6AF, United Kingdom.

The business of the AGM will be to consider and, if thought fit, pass the resolutions below. All resolutions will be proposed as ordinary resolutions. Explanations of the resolutions are given in the Explanatory Notes on page 4 of this document and additional information on voting at the Annual General Meeting can be found on pages 7 to 8. All resolutions will be put to vote on a poll.

Certain of the resolutions that shareholders of the Company will be asked to consider may not be familiar to them because, unlike many companies with shares traded on the Nasdaq Capital Market, the Company is incorporated under the laws of England and Wales and is therefore subject to the U.K. Companies Act 2006 (the ‘‘Companies Act’’). The Companies Act obliges the Company to propose certain matters to shareholders for approval that would generally not be subject to periodic approval by shareholders of companies incorporated in the United States but are routine items for approval by shareholders of companies incorporated in England and Wales.

THAT the directors’ remuneration report of the Company for the financial year ended March 31, 2022, as set forth on pages 63 to 81 of the 2022 Annual Reports and Accounts but excluding the directors’ remuneration policy set out on pages 73 to 81, be approved.

The Board is required to lay its annual reports and accounts before a general meeting each year. The 2022 Annual Reports and Accounts comprise the Company’s directors’ report, strategic report, directors’ remuneration report and annual accounts and auditor’s report for the financial year ended March 31, 2022, prepared in accordance with the Companies Act.

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, 2022, prepared in accordance with the Companies Act. The Company is required to seek shareholders’ approval of this report (excluding the directors’ remuneration policy it contains). The directors’ remuneration report can be found on pages 63 to 81 of the 2022 Annual Reports and Accounts (excluding the directors’ remuneration policy set out on page 73 to 81).

The purpose of this resolution is to seek shareholder approval of the Company’s directors’ remuneration policy set out on pages 73 to 81 of the 2022 Annual Reports and Accounts.

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

The Company has appointed independent non-executive directors for a period of two years from August 23, 2021 to August 22, 2023. In accordance with the terms and conditions of their appointment, their appointment is required to be approved by shareholders at the next AGM after their appointment. As this is the first AGM being held after their appointment, the Company intends to propose resolutions to approve their appointment. If any of these resolutions is not passed, the relevant director’s appointment will be terminated in accordance with the terms of his or her appointment.

The Board considers, that each director seeking confirmation of their appointment contributes effectively and demonstrates commitment to their role. The Board therefore recommends their confirmation. 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.

Brief biographical details of each of the directors to which the resolutions relate are set out set out on pages 5 to 6.

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 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.

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 2022-23.

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.

‘‘Shareholders of record’’ are those persons registered in the register of members of the Company in respect of at least one share in the Company at 23:59 (Eastern Daylight Time) on July 14, 2022 (the ‘‘Record Date’’). 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. Changes to the register of members after the deadline above will be disregarded in determining the rights of any person to attend and vote at the meeting.

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. However, as beneficial owners are not shareholders of record of the relevant Voting Shares, they may not vote their Voting Shares at the Annual General Meeting unless they request and obtain a legal appointment as proxy from their broker or agent.

The proxy form effecting this appointment must be delivered to the Company in accordance with the instructions for the delivery of proxy forms by shareholders of record given below no later than 5:00 p.m. BST on Wednesday, August 17, 2022.

In accordance with the provisions of the Companies Act, and in accordance with the Articles, a shareholder of record is entitled to appoint another person as his or her proxy to exercise all or any of his or her rights to attend and to speak and vote at 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. Such proxies need not be shareholders of record, but must attend the Annual General Meeting and vote in accordance with any instructions given by the shareholder of record. Further details regarding the process to appoint a proxy, voting and the deadlines therefor are set out in the ‘‘Voting Process and Revocation of Proxies’’ section below.

Pursuant to section 527 of the Companies Act, shareholders meeting the threshold requirements set out in that section have the right to require the Company to publish on its website a statement setting out any matter that the members propose to raise at the AGM relating to:

Section 528 of the Companies Act specifies requirements for the Company to make the statement available on the website.
