Advent International, a privately owned firm headquartered in the US, was founded in 1984 and employs approximately 970 individuals. It operates as venture capital and private equity principals, investing in sectors including technology, media and telecoms, financial services, and healthcare.
On September 3, 2026, Definitive Healthcare Corp. (DH) announced it received a non-binding take-private offer from Advent International L.P. to acquire the company's remaining Class A common shares and Definitive OpCo Units not already owned by Advent or founder Jason Krantz for $1.02 per share or unit in cash. Concurrently, Definitive Healthcare named Clay Ritchey CEO. Earlier the same day, Bank of America shifted its rating on Definitive Healthcare to "No Rating" following the acquisition proposal announcement, citing takeover speculation as the primary driver for the stock's price action rather than underlying business fundamentals. This follows the September 2 confirmation by Definitive Healthcare's special committee of the board that it received Advent International's non-binding going-private proposal, which was dated September 1, 2026. Advent International L.P. originally submitted this proposal to acquire all outstanding Class A common stock and associated units not already held by Advent and Executive Chairman Jason Krantz.
