New Mountain Capital is an alternative investment manager with approximately $60 billion in assets under management, operating three integrated platforms: private equity, credit, and net lease strategies. Founded in 1999 and headquartered in New York, the firm deploys capital across defensive growth sectors including healthcare, software, business services, information and data, logistics, specialty chemicals, federal services, financial services, and environmental services.
The firm's investment approach emphasises fundamental research and operational value creation rather than leverage-dependent returns. Portfolio companies benefit from systematic business building support and growth-oriented capital deployment across economically acyclical industries designed to deliver consistent long-term performance through market cycles. This sector specialisation reflects a deliberate strategy to develop deep operating expertise in defensive niches.
New Mountain Capital employs approximately 175 investment professionals who work across the three platforms in a coordinated manner. The firm systematically expands its sectoral expertise over time, allowing it to identify and execute complex transactions in mature, resilient industries. Credit and net lease strategies operate in tandem with private equity holdings, enabling multi-platform solutions for portfolio companies and diversified return generation across the investment portfolio.
