- Net income down 4.8% to $126.9 m; diluted EPS $2.36 vs $2.46. 6M-25 earnings fell 8.6% to $185.6 m.
- Segment mix: Environmental Services rose 2.5% to $1.33 bn, offset by a 14% drop in Safety-Kleen Sustainability Solutions (SKSS) to $219.7 m as base-oil pricing softened.
- Margins: Operating margin slipped 30 bp to 13.6%; cost discipline partially offset weaker product pricing. SG&A decreased 5.9% YoY.
- Balance sheet: Cash $600 m (-$87 m YTD) after $208.7 m capex and $67 m share buybacks. Net debt essentially unchanged at $2.17 bn; leverage ∼2.1× EBITDA (based on trailing twelve-month figures).
- Equity climbed 5.4% to $2.71 bn, helped by earnings and FX gains.
- Cash flow: Operating cash inflow $209.6 m (-11% YoY); FCF negative as heavy growth capex continued (new incinerator build, fleet additions).
- Acquisitions: Finalized purchase accounting for 2024 HEPACO ($392 m) and Noble Oil ($68.7 m); goodwill now $1.48 bn.
- Regulation & tax: Newly enacted U.S. tax law (One Big Beautiful Bill Act) expected to have no material impact.
Overall, Q2 shows resilient service demand but product-linked SKSS weakness and higher depreciation lowered profitability; liquidity and leverage remain solid.
