YORK CAPITAL MANAGEMENT

Jamie Dinan founded York Capital Management and serves as Chair of the firm’s Executive Committee.
Under his leadership, York Capital grew into one of the most respected global hedge funds specializing in event-driven investing, distressed credit, and special situations across international markets.
Dinan helped establish the firm’s reputation for disciplined risk management, deep fundamental research, and the ability to identify mispriced opportunities during periods of corporate change or market dislocation.

In 1991, he raised $3.6 million from former DLJ colleagues to launch York Capital, which would go on to become one of the top event-driven hedge funds on Wall Street.
Dinan has been widely featured in leading financial media outlets, including Forbes, Business Insider, Bloomberg, CNBC, The Wall Street Journal, and Institutional Investor, for his insights on markets, investing, and risk management.
