[SCHEDULE 13D/A] ReNew Energy Global plc SEC Filing

Rhea-AI Filing Summary

Amendment No. 4 reports that Abu Dhabi Investment Authority and related entities jointly disclose beneficial ownership of 58,170,916 Class A ordinary shares, representing 23.8% of the outstanding Class A shares based on a total of 244,405,376 shares. The filing adds a best and final non-binding proposal from the consortium to acquire the issuer at $8.15 per share on a fully diluted basis. The Revised Proposal is explicitly non-binding and does not create any agreement until definitive documents are executed. The amendment also lists prior agreements and exhibits that document the consortium structure and prior proposals.

Positive

• Consortium disclosed a clear purchase price of $8.15 per share as its best and final offer
• Large disclosed stake of 58,170,916 shares representing 23.8%, providing meaningful influence

Negative

• Proposal is explicitly non-binding, so no transaction is assured
• No definitive agreement or financing details are disclosed in this amendment, leaving execution risk

Insights

Corporate Finance Analyst

TL;DR: A large strategic stake and a $8.15 non-binding buyout proposal materially alter control dynamics.

The filing shows a substantial 23.8% stake via ADIA and affiliates, which is large enough to influence board-level outcomes if coordinated with other holders. The Revised Proposal at $8.15 per share is the consortium's stated best and final offer and is presented on a fully diluted basis.

The offer's non-binding status means no transaction exists yet; material investor outcomes depend on whether definitive agreements are reached and on competing bids or board responses in the near term.

Investor Relations Specialist

TL;DR: The amendment increases transparency on ownership and the acquisition attempt but confirms uncertainty.

Filing the Revised Proposal and enumerating exhibits clarifies the consortium participants and the deal process, which helps stakeholders assess near-term strategic risk to the public float. The detailed exhibit list ties this amendment to earlier proposals and governance arrangements that shape execution pathways.

Stakeholders should monitor whether a definitive agreement is announced and any supplementary disclosures regarding financing, regulatory clearances, or competing offers within customary transaction timelines.
