One Equity Partners Closes $1 Billion Continuation Fund Co-led by AlpInvest Partners and HarbourVest Partners

Transaction to Enable Continued Acquisitions and Growth for USCO SpA and DWK Life Sciences

NEW YORK – May 10, 2023 – One Equity Partners, (“One Equity” or “OEP”) a middle market private equity firm, today announced the close of a $1 billion Continuation Fund (“the Fund”), co-led by AlpInvest Partners, a subsidiary of global investment firm Carlyle (NASDAQ: CG), and HarbourVest Partners that will support continued growth for two European portfolio companies.

The additional capital will help drive transformational acquisitions and continued growth at aftermarket construction parts manufacturer and distributor USCO SpA and laboratory glassware manufacturer DWK Life Sciences.

“One Equity Partners is proud to partner with AlpInvest and HarbourVest on this oversubscribed transaction that generates liquidity and attractive returns for our existing investors in two proven assets and gives us the opportunity to continue driving acquisitions and growth,” said David Lippin, Managing Director and Head of Investor Relations at One Equity. “We were able to garner support in this transaction from new investors and institutions across both North America and Europe who recognized the firm’s strong track record of creating and driving value via its unique transformative combination strategy.”

USCO, based in Modena, Italy, supplies aftermarket and OEM parts to the earthmoving machinery industry globally, including repair components and ground-engaging and undercarriage parts. Since investing in April 2017, OEP has helped drive completion of six acquisitions providing USCO with a global distribution network, OEM quality engineering capability and a competitive manufacturing footprint worldwide. Together with an organic growth push by the company, a market-leading earthmoving industry parts supplier was created.

DWK Life Sciences, based in Wertheim, Germany, is a leading global manufacturer of premium laboratory glassware, storage solutions and other products for the life science and pharmaceutical end markets. Employing a transformational acquisition strategy, OEP first acquired Duran Group in February 2015, a leading brand and global manufacturer of premium borosilicate glass used primarily for laboratory glassware. This was followed by the acquisitions of Wheaton, a laboratory consumables business in September 2015, and laboratory and scientific glassware manufacturer and distributor Kimble Chase in October 2016, to create DWK Life Sciences. The subsequent acquisition of tubular glass packaging material maker Müller + Müller in September 2020 helped expand DWK’s presence in the fast-growing pharmaceutical packaging segment.

“This Continuation Fund will allow OEP to enable further expansion for two strong investments within our industrials and healthcare portfolio,” said One Equity Managing Director Steven Lunau. “Our long-standing investment strategy of helping drive transformative and accretive acquisitions has allowed us to work with management to build these businesses into recognized industry leaders.”

“We are pleased to further our longstanding partnership with One Equity and its investors on this transaction, which aligns with our strategy of investing with strong GPs managing attractive assets that have strong growth potential,” said  Julian Rampelmann, Managing Director at AlpInvest. 

“We are delighted to partner with One Equity on this transaction. They have worked with strong management teams to build market-leading companies and we look forward to supporting their growth trajectories over the next phase of ownership,” said Greg Ciesielski, Managing Director at HarbourVest Partners. 

Kirkland and Ellis served as legal counsel on the transaction and Moelis & Co. served as advisor on the transaction for One Equity Partners. Ropes & Gray acted as legal counsel for AlpInvest Partners. Debevoise & Plimpton acted as legal counsel for HarbourVest Partners.
