EnviroServe has about $250M revenue and ~$27M adjusted EBITDA, with ~85% recurring revenue.

How this was made
The 30-second read
Why it matters
For CLH, the key tradable elements are deal size, expected close timing (H2 2026), synergy magnitude ($25M over two years), and the implied post-synergy EBITDA multiple (~9x), plus financing via cash and additional debt.
Market read
This is a definitive M&A catalyst with explicit synergy and valuation framing, likely driving immediate deal-arbitrage and acquirer sentiment positioning.
What to watch
Financing mix (cash plus additional debt) can affect leverage and credit spreads; regulatory approvals and integration execution timing could delay accretion beyond the modeled two-year synergy window.
Background

Ticker impact
Clean Harbors agreed to acquire EnviroServe for $470M cash, targeting H2 2026 close and ~$25M cost synergies.
Likely positive bias while deal certainty and synergy accretion narrative dominate, but volatility around regulatory/financing details.
A definitive acquisition with quantified synergies and implied post-synergy EBITDA multiple is a direct, time-sensitive fundamental catalyst for the acquirer.
Market effects

No specific regional demand shift stated; impact is primarily US footprint expansion via 48-state permits.
Limited global relevance; transaction is US-focused with permits across states.
Counterpoint
Synergy and accretion assumptions may be optimistic versus integration costs, and the implied multiple could be less attractive if EBITDA quality or recurring revenue durability is weaker than stated.
