What's the endgame? The capital backs Ambient's next phase of growth — expanding technical capabilities and its national footprint across the full HVAC lifecycle. The company traces its roots to Gil-Bar, which Sbarra co-founded in Brooklyn in 1986, and has since grown by uniting local HVAC firms while preserving their regional identities.
Why it matters? Chris Bertrand, a partner at BDT & MSD, framed the investment as "central to our flagship strategy of providing patient, aligned capital to exceptional closely held businesses." That signals a long-hold approach rather than a control-changing buyout.
The transaction is expected to close in the fourth quarter of 2026, subject to customary closing conditions.
