Insights

M&A analyst

Consortium signals intent with a best and final non-binding bid.

A group led by Masdar, CPP Investments, an ADIA subsidiary, and Sumant Sinha submitted a best and final non-binding offer to acquire ReNew’s shares they do not already own. This indicates coordinated buyer interest but remains preliminary without binding terms or a disclosed price.

Because the offer is non-binding, completion depends on formal agreements, customary approvals, and deal terms that are not included in the excerpt. The presence of existing shareholders among bidders may simplify negotiations, but specifics are not provided.

Actual impact will hinge on confirmed consideration and structure if parties proceed. Subsequent company disclosures may provide pricing, conditions, and timing.
