Mangrove Partners IM, LLC is a hedge fund and SEC-registered investment adviser headquartered in Greenwich, Connecticut.

Mangrove serves institutional and high-net-worth investors, focusing on opportunistic value investing and special situations across public and private markets.

Investment Strategy

Mangrove Partners employs a value-oriented, opportunistic investment strategy targeting special situations, catalyst-driven investments, and deep fundamental research. The firm focuses on long and short equity positions—often in misunderstood, undervalued or distressed securities, aiming to unlock returns through rigorous due diligence, active engagement, and event-driven strategies, primarily within North American markets but with global capability. Mangrove Partners seeks asymmetric risk-reward by investing in complex corporate actions, restructurings, and credits, with a philosophy centered on capital preservation and opportunistic alpha generation.
