Clean Harbors (ISIN US1844961078) completed the EnviroServe and ES&H acquisitions for USD 775 million on October 5, 2026, according to Business Wire. The deal expands the companys technical services and field services businesses, making execution of the integration the central issue for Clean Harbors stock.

USD 775 million expansion

The company funded the combined purchase price with available cash and a recently completed USD 600 million senior notes offering. The notes carry a 6.250 percent annual interest rate and mature in 2034, according to StockTitan.

EnviroServe closed on October 2, 2026, while ES&H closed on September 18, 2026. The financing therefore links the latest growth push to higher debt service, a relevant counter-factor as management integrates two businesses.

Revenue growth supports the deal

Clean Harbors reported USD 1.74 billion of revenue in the second quarter of 2026, up 11.90 percent year over year, according to MarketBeat. Adjusted earnings per share reached USD 3.22 versus USD 2.81 consensus, a USD 0.41 comparison advantage.

The comparison with the second quarter of 2025 is also clear: earnings per share were USD 2.36 in the prior-year period, versus USD 3.22 in the latest quarter. For investors, the acquisition case depends on converting this operating momentum into the expected benefits without weakening balance-sheet flexibility.
