New Mountain Capital

What New Mountain Capital does

New Mountain Capital is a New York-based alternative investment firm founded in 1999 by Steven Klinsky, managing approximately $60 billion in assets across private equity, strategic equity, credit, and net lease real estate strategies. The firm invests in more than 80 portfolio companies across carefully selected "defensive growth" industries — economically acyclical sectors such as healthcare/health tech, specialized software, business services, information and data, logistics, infrastructure services, financial services, and specialty chemicals. Its investment approach centers on intensive fundamental research, business building through organic growth and add-on acquisitions, moderate use of acquisition debt, and proactive top-down sector identification before auction processes begin, formalized through a proprietary framework of 24 Key Sustainability Metrics used in all due diligence.

The firm's revenue model is built on management fees and carried interest on a series of institutional fund vehicles, complemented by net lease rental income, BDC investment income (via majority-owned Nasdaq-listed NMFC), and reinsurance premium income through the newly launched VictoryRe platform. Distribution occurs through direct institutional fundraising to pension funds, insurance companies, endowments, family offices, RIAs, and HNW individuals, with a new Wealth Solutions team extending access to wealth management channels. The platform operates across the Americas, Europe, and Asia Pacific through offices in New York (global HQ), Tokyo, Seoul, and Mexico City, supported by approximately 300 investment professionals and staff including a 22-member Senior Advisor network.

New Mountain has built a vertically integrated multi-strategy platform: the flagship control-oriented New Mountain Partners funds (I–VII), the Strategic Equity non-control funds (SEF I, SEF II), the Credit platform spanning private credit, CLOs, and the NMFC BDC, a ~$4B Net Lease real estate portfolio, and two 2026-era expansions — Atlas (GP-led secondaries) and VictoryRe (reinsurance). Notable portfolio platforms include Smarter Technologies (AI-enabled healthcare RCM), Grant Thornton Advisors (multinational professional services), Azuria Water Solutions (water/wastewater infrastructure), and a growing cluster of power and grid engineering firms. Track record includes zero private equity portfolio company bankrupthips, a 0.2% annualized realized/unrealized loss ratio, and major realizations including Avantor ($3.8B IPO, 2019), Cumming Group ($3B sale to Leonard Green, 2026), Pearce Services ($1.2B+ to CBRE, 2025), and Citrin Cooperman (~$2B to Blackstone, 2025).
