Japan’s Mizuho Financial Group has agreed to acquire US investment bank Greenhill in a deal worth around US$550 million, including assumed debt.

Greenhill is a leading independent investment bank focused on providing financial advice on significant mergers, acquisitions, restructurings, financings and capital raising to corporations, partnerships, institutions and governments in various sectors. Following the completion of the transaction, Greenhill will operate globally as Mizuho's M&A and restructuring advisory arm. The transaction will enable Mizuho's deal to accelerate its investment banking growth strategy, drawing on Greenhill's experience in advising clients on major mergers and acquisitions, restructurings and capital-raising operations. 

Citi and Mizuho are acting as financial advisors, and Paul, Weiss, Rifkind, Wharton & Garrison LLP and Davis Polk & Wardwell LLP are acting as legal advisors to Mizuho. Houlihan Loki serves as financial advisor and Wachtell, Lipton, Rosen and Katz serve as legal advisors to Greenhill.

The transaction is expected to be closed by the end of 2023.
