What One Rock Capital Partners does
One Rock Capital Partners is an operationally-focused, value-oriented private equity firm headquartered in New York, founded in 2010 by Scott Spielvogel and Tony Lee. The firm primarily invests in "Real Economy" middle-market sectors — specifically Chemicals & Process Industries, Food & Beverage Manufacturing & Distribution, Specialty Manufacturing, and Business & Environmental Services — with a deliberate focus on complex situations including corporate carve-outs, turnarounds, and operational restructurings. Since inception, One Rock has raised over $10 billion in cumulative capital, completed 65+ acquisitions, and built a portfolio spanning 650+ facilities, 55,000+ employees, and 30+ countries.
The firm's core differentiator is its Operating Partners model — senior industrial executives embedded across portfolio companies to drive hands-on operational improvement — combined with the global resources of strategic partner Mitsubishi Corporation, which extends One Rock's cross-border deal sourcing and execution capabilities. Revenue is generated through conventional private equity fund management economics: management fees on committed and invested capital across multi-vintage funds, supplemented by carried interest realization upon portfolio exits (recent examples include the $360 million sale of NORPAC to International Paper in 2026). Notable recent transactions include Constantia Flexibles (2023, global packaging, 7,000+ employees), Europe Snacks (2024, European savory snacks), EnviroServe (2023, U.S. environmental services), Flexsys (2021, Eastman tire additives carve-out for $800M), and Kensing (2021, BASF specialty chemicals carve-out).
The firm is privately held with no publicly traded equity, employs 101–250 professionals across offices in New York, Los Angeles, London, and Dubai, and is regulated by the DFSA in the UAE through its Dubai Representative Office. Its business model is distribution-light: deal sourcing relies on industry relationships, repeat counterparty networks (BASF, Eastman, Emerson, Wendel, Silverfleet), and Mitsubishi's corporate channel rather than traditional marketing or sales infrastructure.
