On August 12, 2026, Clean Harbors announced a definitive agreement to acquire EnviroServe for $470 million in cash from an affiliate of One Rock Capital Partners. The transaction is expected to close in the second half of 2026, subject to regulatory approval and customary conditions. EnviroServe operates a network of 40 locations across 48 states with approximately $250 million in annual revenues and $27 million in Adjusted EBITDA. Clean Harbors anticipates realizing $25 million in cost synergies within two years, resulting in a post-synergy acquisition multiple of approximately nine times Adjusted EBITDA. The company plans to fund the deal using available cash and additional debt financing. This acquisition expands Clean Harbors' environmental services footprint through EnviroServe's 10-day transfer facilities, rail cleaning capabilities, and specialized fleet.
