News Summary
PositiveClean Harbors delivered record Q1 2026 revenue of $1.46B with an EPS beat and raised full-year 2026 Adjusted EBITDA guidance by $40M to $1.24-1.30B, driven by strong Environmental Services margin expansion (16th consecutive quarter of improvement) and Kimball incinerator ramp-up. Strategic acquisitions (DCI for $130M, Terra Nova for $225M) and regulatory tailwinds from EPA/DoD PFAS guidance recognition position the company for accelerating PFAS-related revenue growth (25-35% pipeline growth), though management transitions are underway with the retirement of Founder/Chair Alan McKim and General Counsel Michael McDonald.

- •Safety-Kleen segment revenue declined 7.1% YoY due to lower product pricing
