We are tracking PremiStar's add-on acquisition of Mechanical Service and Systems, based in Salt Lake City, announced June 10, 2026, with advisor D.A. Davidson confirming the following day. This marks PremiStar's first entry into the Utah market.
Deal value undisclosed; no multiple disclosed. D.A. Davidson acted as exclusive financial advisor to the seller.
Mechanical Service and Systems covers commercial and industrial HVAC, plumbing, and building automation. Post-close, PremiStar operates sixty-two branches across nineteen states with more than three thousand one hundred employees.
This is roughly the fortieth add-on for the platform, which Partners Group backs after acquiring legacy Reedy Industries in 2021 at about $1,000,000,000 enterprise value. Secondary analysis puts total platform funding near $2,090,000,000.
Our data indicates PremiStar is the most active tracked platform this window, with two confirmed add-ons and steady geographic expansion. Partners Group continues compounding scale through disciplined regional infill rather than headline transactions.
