New Mountain Capital has closed its second non-control private equity vehicle, New Mountain Strategic Equity Fund II, L.P. and related vehicles (SEF II), with $1.2 billion in total commitments, exceeding the fund’s stated $1 billion “hard cap” after limited partners supported an increase to accommodate additional demand. The New York-based alternative investment firm said general partner commitments totaled more than $150 million, making the GP the fund’s largest investor and representing commitments from roughly 115 internal team members.
SEF II is dedicated to minority, non-control investments in founder- and sponsor-backed businesses, with New Mountain positioning the strategy as partnership-oriented and focused on operational support and business-building rather than control buyouts. The firm said the fund will continue its emphasis on “defensive growth” sectors that it views as acyclical, applying a research-driven underwriting approach and operational value-creation resources to middle-market companies.
New Mountain’s first strategic equity fund, SEF I, closed in 2020 with approximately $640 million and is now fully invested, the firm said, and it generated a “significant level” of co-investment opportunities for its limited partners. For SEF II, New Mountain said the investor base includes pension funds, insurance companies, asset managers, endowments, family offices, RIAs and high-net-worth individuals, and that a majority of SEF I investors returned for the successor fund.
The firm said SEF II will focus on targeted areas including infrastructure services, life sciences and advanced materials, healthcare technologies, advanced data and analytics, software, financial and insurance services, and technology-enabled business services, among others, using minority investments where it can provide operational and strategic support. Ahead of the final close, SEF II invested in one platform company, Wipfli LLP, which New Mountain described as a middle-market provider of accounting, tax and advisory services, citing prior investments in the accounting sector including Citrin Cooperman Advisors and Grant Thornton through its control private equity funds.
New Mountain said it now manages approximately $60 billion in assets across private equity, strategic equity, GP-led single-asset secondaries, credit and net lease strategies, and employs more than 300 professionals. Simpson Thacher & Bartlett served as legal advisor to the fund.
