What the filing says
Clean Harbors agreed to acquire EnviroServe, a national environmental and waste management provider with 40 locations and ~2,500 customers, from One Rock Capital Partners for $470 million in cash. The target generated ~$250M revenues and ~$27M adjusted EBITDA annually. Clean Harbors projects $25M in cost synergies over two years, yielding a 9× post-synergy EBITDA multiple; closing expected H2 2026.
Why this rating
Deal is ~4% of Clean Harbors' $11.7B market cap—material but not transformational. Strategic bolt-on with synergies and accretion. Financing via cash and debt manageable for large-cap company.
