Greenhill & Co

What Greenhill & Co does

Greenhill & Co is an investment bank founded in 1996 in New York City, specializing in financial advisory services for large corporations, institutional investors and private equity clients. Its core offerings span M&A advisory (buy-side, sell-side, special committee, defense and activism), restructuring advisory (debtor, creditor and distressed M&A) and private capital advisory (primary fundraising and secondary liquidity for PE, credit, real asset and infrastructure firms). These are supported by capital markets and corporate banking product teams covering Equity Capital Markets, Debt Capital Markets, Leveraged Finance, Corporate Banking, and Derivative Risk Solutions.

In 2023, Greenhill was acquired by Mizuho Financial Group and now operates as the investment banking division of Mizuho Americas under the brand 'Mizuho | Greenhill'. The combined platform deploys approximately 1,000 bankers across 22 offices worldwide, organized into nine industry groups (Consumer+Retail, Energy, Financial Institutions, Financial Sponsors, Healthcare, Industrials, Power+Utilities+Infrastructure, Real Estate, and Technology+Media+Telecom). Mizuho's $2 trillion balance sheet and A credit rating underwrite the platform's capital and execution capability, while thought leadership is distributed via the 'Beyond the Obvious' content platform.

Greenhill generates revenue through transaction fees on M&A and capital markets advisory mandates, professional services fees on restructuring and private capital advisory engagements, and integrated fees across the full Mizuho product suite. The go-to-market motion is enterprise field sales through direct senior banker relationships with corporate boards, sponsors and institutional investors. Post-acquisition, the firm has expanded its competitive positioning against bulge-bracket franchises, evidenced by industry awards including Best Bank - Corporate Banking in the U.S. (Crisil Coalition Greenwich, 2026) and Financial Advisor of the Year, North America (IJGlobal, 2025).
