The PE group is based in Boston and won Mergers & Acquisitions’ 2015 M&A Mid-Market Award for Private Equity Firm of the Year.  In a separate announcement, Audax Private Equity portfolio company Active Day acquired acquired adult day car services provider Lowell Elder Care.

Private equity firms have been raising loan funds, reinforcing investors’ interest in the private debt landscape, which is not yet as crowded as it is among private equity firms. NXT Capital LLC closed its fourth debt fund at $900 million; the Carlyle Group LP (Nasdaq: CG) raised a CLO fund; and Monroe Capital closed a $800 million credit fund.
