ReNew Energy Global Plc announces an agreement in principle on the key financial terms of a possible cash offer from Masdar, CPP Investments, ADIA and Sumant Sinha

ReNew Global Energy plc (“ReNew” or the “Company”) today announces that it has reached an agreement in principle on the key financial terms of a possible cash offer (the “Possible Offer”) from Abu Dhabi Future Energy Company PJSC-Masdar (“Masdar”), Canada Pension Plan Investment Board (“CPP Investments”), Platinum Hawk C 2019 RSC Limited as trustee for the Platinum Cactus A 2019 Trust (“Platinum Hawk”) (a wholly owned subsidiary of the Abu Dhabi Investment Authority, “ADIA”) and Sumant Sinha (the Founder, Chairman and CEO of ReNew) (together with Masdar, CPP Investments and Platinum Hawk, the “Consortium”) to acquire the entire issued and to be issued share capital of the Company not already owned by members of the Consortium for cash consideration of US$8.15 per share.

Proceeding with the Possible Offer is conditional on, inter alia, reaching agreement on the other terms and the conditions of any offer, including as to regulatory clearances, and the completion of confirmatory due diligence from the Consortium.

The Special Committee of ReNew (“Special Committee”), led by Manoj Singh, the Lead Independent Director, and advised by Rothschild & Co and Linklaters, has indicated to the Consortium that the key financial terms of the Possible Offer represent a value that it would unanimously recommend to ReNew shareholders to vote in favour of, should a final binding offer be made on these terms and subject to agreement on all other terms and conditions of such Possible Offer and definitive transaction documentation being agreed.

The Special Committee has also engaged with JERA Power RN B.V. (a wholly owned subsidiary of JERA Nex Limited) (“JERA Nex”), which owns approximately 11.6% of the issued share capital of ReNew1and 25.7% of the issued share capital of ReNew not already owned by the Consortium in relation to the Possible Offer2. JERA Nex has indicated that were the Special Committee to make a unanimous recommendation on customary terms to ReNew shareholders to vote in favour of a final binding offer made on these key financial terms, then - subject to JERA Nex being satisfied with all other terms and conditions of such final binding offer and with the definitive transaction documentation that had been agreed - JERA Nex is currently minded to vote in favour of this offer should it proceed to a scheme of arrangement vote.

Key terms of the Possible Offer

The Possible Offer represents:

No assurance can be given regarding the likelihood, terms or details of a potential transaction resulting from the Possible Offer received from the Consortium or any other potential transaction. Further decisions or disclosures by the Special Committee will be made as appropriate or required.

A further announcement will be made when appropriate.
