About Greenhill & Co INC

Greenhill & Co., Inc. (ticker: GHL) is a U.S.-based investment banking advisory firm that was historically listed on the NYSE in the United States. Founded in 1996 by Robert F. Greenhill, a former senior executive at Morgan Stanley and Smith Barney, the firm built its reputation as an independent, senior-led advisory boutique. Its headquarters are in New York, and its business model has traditionally relied on highly experienced bankers providing strategic advice to corporations, financial sponsors, institutions, and governments on complex transactions. Greenhill’s core activities have centered on three main service lines: mergers and acquisitions (M&A), financing and restructuring, and capital advisory. In practical terms, that means advising clients on buy-side and sell-side transactions, mergers, recapitalizations, debt restructurings, capital raises, and advisory work for institutional investors in alternative assets. The company has long emphasized that it is not a balance-sheet-driven business; instead, its value proposition comes from advisory expertise, sector knowledge, and the seniority of its client teams. That model makes earnings more sensitive to transaction volumes and market conditions, but it also allows for a focused, high-margin advisory franchise when deal activity is strong. From a competitive standpoint, Greenhill has operated in a crowded advisory market alongside other independent boutiques such as Lazard, Evercore, and PJT Partners, as well as the advisory divisions of major universal banks. Its differentiation has historically come from independence, confidentiality, cross-border execution, and a broad sector footprint. The firm states that it has worked across most major industry groups and on strategically significant transactions. Greenhill also developed a meaningful international presence over time, with offices across North America, Europe, Asia, and Australia, including New York, London, Paris, Frankfurt, Hong Kong, Singapore, Sydney, Toronto, and other major financial centers. For investors, the key appeal of Greenhill has been its pure-play exposure to M&A and restructuring cycles. Revenue trends are closely tied to corporate confidence, credit conditions, sponsor activity, and the broader backdrop for capital markets. In periods of rising deal flow, the model can generate strong operating leverage; in slower markets, activity can soften materially. This makes Greenhill particularly relevant for investors looking at SEC Form 4 insider transactions, because insider behavior in advisory firms can sometimes reflect management’s view on the transaction cycle and the outlook for advisory demand. A major recent development was the 2023 announcement that Mizuho would acquire Greenhill’s M&A and restructuring advisory business, underscoring ongoing consolidation among independent advisory houses. That transaction is an important context item for any analysis of recent filings and insider activity. Overall, Greenhill remains a notable name in global investment banking advisory, with a long history, a recognized brand, and a business model closely linked to the health of worldwide dealmaking.
