Investment thesis

New Mountain Capital applies a 'defensive growth' investment philosophy centered on business building and growth in economically acyclical industries. Its private equity strategy acquires and builds high-quality leaders in carefully selected defensive growth sectors. Its credit strategy extends the same philosophy to corporate lending opportunities, while its net lease strategy targets operationally critical real estate assets owned by sponsor-backed companies in defensive growth industries. The firm emphasizes growth and value creation rather than financial engineering alone.
