A definitive agreement has been signed to acquire EnviroServe for $470 million in cash, expanding the environmental services footprint with 40 locations and a national customer base. The deal is expected to close in the second half of 2026, funded by available cash and new debt. EnviroServe generates roughly $250 million in revenue and $27 million in adjusted EBITDA, and $25 million in cost synergies are projected over two years, bringing the post-synergy multiple to about 9x adjusted EBITDA. This is a meaningful tuck-in acquisition that strengthens the company's Technical Services and Field Services segments, though it adds leverage and integration risk.
