Frequently asked questions

Who runs investment decisions at Adelphi Capital Partners?

Joe May, Founder and Managing Partner, leads investment decisions. He built the firm after a 25-year career at The Graham Group and as a founder of Graham Partners, where he sat on the investment committee and shared responsibility for sourcing, structuring, and exiting deals. Adelphi’s website lists no other investment committee members, and the operating partners appear focused on diligence and portfolio-company value creation.

What kind of companies does Adelphi acquire?

Adelphi targets founder- and family-owned manufacturing and industrial-services businesses in the lower middle market, with revenue between $10 million and $100 million and EBITDA of $3 million to $15 million. The firm’s disclosed activity and operating partner backgrounds point toward building products, industrial technology, metal and consumer packaging, environmental-control systems, and advanced-manufacturing subsectors.

Does Adelphi invest outside the United States?

The firm’s stated geographic focus is the United States and Canada. Joe May’s prior experience at Graham Partners included cross-border M&A in France, Canada, the United Kingdom, Poland, Brazil, and Argentina, but Adelphi’s current criteria and portfolio appear concentrated in North America.
