Strong gains: Several notable projects and macroeconomic tailwinds propelled Clean Harbors’ topline financial metrics during the second quarter. A variety of factors contributed to that performance, including global supply disruptions of refined products driving demand for Clean Harbors’ services. M&A announcement: In its earnings release, Clean Harbors announced a $305 million all-cash deal to acquire Louisiana-based ES&H, subject to final negotiations. ES&H also has an emergency response readiness plan development and training business, Forefront, which Clean Harbors plans to expand nationwide. Data center offering: Clean Harbors is also spending about $50 million on specialty equipment, tankage and vehicles for data center-related services.
