 to $473.8 million in the same period of 2024. This $37.8 million increase in operating cash flows was primarily due to improvement in working capital balances as compared to the prior year period, lower environmental expenditures and lower cash paid for taxes for the nine months ended September 30, 2025 compared to the same period in 2024.

Net cash used in investing activities

Net cash used in investing activities for the nine months ended September 30, 2025 was $276.6 million, a decrease of $536.4 million from the comparable period in 2024. In the nine months ended September 30, 2024, we paid $474.0 million for acquisitions, including the purchase of HEPACO and Noble. Additions to property, plant and equipment, net of proceeds from sale and disposal of fixed assets, decreased $75.6 million, primarily due to notable project spend of $63.3 million on the Kimball incinerator strategic project in the nine months ended September 30, 2024. Partially offsetting these lower cash outflows was a $13.5 million lower cash inflow due to the timing of transactions within our wholly owned captive insurance company.

Net cash (used in) from financing activities

Net cash used in financing activities for the nine months ended September 30, 2025 was $166.5 million, as compared to net cash from financing activities of $408.6 million for the nine months ended September 30, 2024. The primary difference in financing activities was the incurrence of term loans net of discount and deferred financing costs of $491.1 million in 2024 to fund the acquisitions executed during the period. Additionally, in 2025, the Company paid $86.8 million more for repurchases of common stock while also receiving an additional $3.4 million in proceeds from the ESPP.

Adjusted Free Cash Flow

Management considers adjusted free cash flow, a non-GAAP measure, to be a measure of liquidity that provides useful information to management, creditors and investors about our financial strength and our ability to generate cash. Additionally, adjusted free cash flow is a metric on which a portion of management incentive compensation is based. We define adjusted free cash flow as net cash from operating activities, less additions to property, plant and equipment, plus proceeds from sales or disposals of fixed assets. When necessary, management adjusts for the cash impact of items derived from non-operating activities. Additionally, adjusted
