NEW YORK, July 7, 2025 – One Rock Capital Partners, LLC (together with its affiliates, “One Rock”), a value-oriented, operationally focused private equity firm, announced today the successful final closing of aggregate capital commitments of $3.97 billion for two new funds and related vehicles, including One Rock’s latest flagship fund: One Rock Capital Partners IV, L.P. (“Fund IV”), and its inaugural lower middle market-focused fund: One Rock Emerald Fund, L.P. (“Emerald Fund”). The closing marks the firm’s largest fundraise to date, surpassing the size of its prior fund which closed at $2.01 billion in 2021. As of the final closing, One Rock manages more than $10 billion of cumulative capital commitments.

Founded in 2010 by Managing Partners Tony W. Lee and R.

Since its inception, One Rock has invested in 67 companies, including platform investments and add-on acquisitions.

“We are deeply grateful for the strong support from our long-standing investors and are honored to welcome a diverse group of new institutional partners from around the world,” said R. Scott Spielvogel. “In a period of significant global uncertainty, we believe our track record of creating value by investing in complex situations in the industrial sectors of the economy continues to resonate within the institutional investor community.”

“Our investors’ support enables us to continue executing the value-oriented and operationally focused strategy that has defined One Rock for over fifteen years,” added Tony W. Lee. “Our approach is designed to be consistent across Fund IV and the Emerald Fund: to leverage the expertise and operational capabilities of our investment team and Operating Partners in identifying compelling opportunities, which are often obscured by complexity, and driving operational improvement in partnership with our portfolio companies. Our strategy remains focused on creating meaningful value at all points in the economic cycle.”

“We believe this milestone reflects the strong endorsement of an investor base diversified by type and geography,” said Managing Director, Head of Investor Relations & Capital Formation, Deepa Patil Madhani. “We are privileged to have earned support from a mix of public and private pensions, insurance companies, corporates, asset managers, endowments and foundations, and family offices, with six continents represented in our investor base.  We’re honored to continue serving as responsible stewards of our investors’ capital in an effort to consistently deliver strong results.”
