One Equity Partners

What One Equity Partners does

One Equity Partners (OEP) is a middle-market private equity firm founded in 2001 and headquartered in New York, with investment activity spanning North America and Europe. The firm invests across three core sectors — industrial, healthcare, and technology — and reports $13.5B+ in capital deployed across 125+ platform investments since inception. OEP's stated thesis centers on "TransformationalCombinations": buyouts, carve-outs, simultaneous mergers, and roll-up platforms, with operational support and add-on M&A as the primary value-creation levers. Named portfolio companies span specialty chemicals (Bozzetto, Clayens), industrial automation and robotics (Comau, F.EE Automation), hydraulic and engineered systems (Montanhydraulik, Leviat), safety technology (BARTEC), energy services (EthosEnergy, Guidant), IT services (Mythics Emergent Group, Digital Value, Kirey/Synergyc), wholesale distribution (Kitwave), and aftermarket parts (Wheeler Fleet Solutions, Associated Spring), among others.

The firm's core "product" is its private equity investment platform — a direct, relationship-driven origination model targeting owner-operators and corporate parents of middle-market businesses. There is no proprietary software or technical platform disclosed; OEP monetizes through standard PE economics: management fees on committed/invested capital across its funds plus carried interest on realized investment gains. Deal examples include the $175M buyout of Associated Spring from Barnes Group, the £400M carve-out of Amey Group from Ferrovial, a $150M equity investment in Polar Semiconductor, and the $2.1B exit of Eco Material Technologies to CRH. The firm also benefits from a JPMorgan Chase-sponsored SPAC vehicle (One Equity Partners Open Water I Corp., OTCMKTS:OEPWU) that provides an alternative capital-markets channel for deal execution.

OEP's go-to-market is sales-led and relationship-driven, with no traditional sales channels; deal flow originates from long-standing relationships built since 2001 with management teams, advisors, and corporate divestiture programs. The firm markets itself primarily through its corporate website, LinkedIn presence, and PR distribution via businesswire/PR Newswire/GlobeNewswire. Customer concentration at the portfolio level is diversified across multiple sectors and geographies, though as a PE firm its LPs are undisclosed. Headcount is in the 11-50 range, consistent with a lean middle-market platform.
