Environmental Services direct revenues for the nine months ended September 30, 2025 increased $113.4 million from the comparable period in 2024 driven by incremental revenues from our legacy operations and acquisitive growth. Technical Services revenue increased $92.1 million from the comparable prior year period driven primarily by higher incineration and landfill volumes. On a comparative basis and excluding the impacts of the new incinerator in Kimball, Nebraska, utilization at our incinerators was 90% in the first nine months of 2025 as compared to 85% in the same period in 2024. Including the new Kimball incinerator, utilization at our incinerators was 85% during the nine months ended September 30, 2025. Revenues from Safety-Kleen core service offerings for the nine months ended September 30, 2025 grew by $51.6 million from the comparable period in 2024 due to improved pricing for our containerized waste, vacuum and parts washer services. Field and Emergency Response Services revenues for the nine months ended September 30, 2025 increased $14.2 million from the comparable period in 2024 driven by incremental revenue from the acquisition of HEPACO in late March 2024, partially offset by lower revenues from emergency response events in the second and third quarters. Revenue from our Industrial Services operations decreased $48.4 million due to lower turnaround activity and related high-value services as compared to 2024. Direct revenues for Canadian operations of the Environmental Services segment decreased by $9.4 million due to foreign currency translation.
