Current report
Financing costs are driven by interest incurred on our outstanding borrowings under our senior secured credit facilities, as well as fees paid on the unutilized capacity of the facility and outstanding letters of credit issued under the facility. Interest is also incurred on outstanding borrowings under the Aircraft Loan and amounts outstanding under our capital lease facilities. Financing costs also include the amortization or write-offs of deferred debt issuance costs and amounts paid under our interest rate swaps. Amounts received related to our interest rate swaps are netted off of Financing Costs.
Current report
The Three And Nine Months Ended September 30, 2025 Compared to the Three And Nine Months Ended September 30, 2024
Current report
Depreciation and Amortization for the three months ended September 30, 2025 remained relatively consistent with the three months ended September 30, 2024 primarily due to the absence of significant changes in the underlying property and equipment and intangible asset base.
Current report
Depreciation and Amortization for the nine months ended September 30, 2025 increased compared to the nine months ended September 30, 2024 primarily as a result of higher property and equipment balances.
Current report
The income tax expense for the three months ended September 30, 2025 increased compared to the three months ended September 30, 2024 primarily as a result of the continued utilization of tax attributes resulting in less indefinite-lived deferred tax assets available to offset the impact of indefinite-lived deferred tax liabilities.
Current report
The Three And Nine Months Ended September 30, 2025 Compared to the Three And Nine Months Ended September 30, 2024
Current report
Remediation and Reuse Segment Adjusted EBITDA for the three and nine months ended September 30, 2025 decreased compared to the three and nine months ended September 30, 2024 due primarily to losses incurred in our renewables business in the current year, partially offset by higher revenues in our water treatment business. Segment Adjusted EBITDA margin decreased as a result of losses incurred in our renewables business. Adjusted EBITDA in this business declined $1.5 million and $5.0 million in the three and nine months ended September 30, 2025, respectively. We anticipate that this business line will be fully wound down by December 31, 2025.

Previous report
Total debt at June 30, 2025 was $273.2 million net of deferred debt issuance costs, which was an increase of $50.6 million compared to December 31, 2024. The increase is primarily driven by the additional usage of our revolving line of credit, under which borrowings increased by $41.4 million, including in connection with the $60.0 million partial redemption of the series A-2 preferred stock in April 2025, which was partially funded by incremental borrowings under our revolving credit facility, and the refinanced term loan in connection with the 2025 Credit Facility, which increased the aggregate amount outstanding by approximately $10.8 million.

Interest expense, net was $4.8 million and $9.8 million in the three and six months ended June 30, 2025, respectively, and $4.0 million and $7.3 million in the three and six months ended June 30, 2024, respectively.

We also leveraged our 2025 Credit Facility to pay a portion of the redemption price for the Series A-2 preferred stock in April and July 2025.
Previous wording
In addition to the impact of seasonality on earnings, our emergency response business exposes us to potentially significant revenue and earnings fluctuations tied to large environmental emergency response projects following an incident or natural disaster or more broad scale events. Total revenue from emergency response related services was $48.5 million and $12.9 million for the three months ended June 30, 2025 and 2024, respectively, and $62.4 million and $28.6 million for the six months ended June 30, 2025 and 2024, respectively. The higher than normal emergency response revenue in the second quarter of 2025 was primarily driven by one large emergency response project. Demand for environmental emergency response services remains difficult to predict and as a result, revenues and earnings in the current and prior years may not be indicative of future results, making those periods particularly difficult comparisons for future periods. Earnings volatility is also driven by the timing of large projects, particularly in our Remediation and Reuse segment, and the impact of acquisitions. As a result of these factors, and because demand for environmental services is not driven by specific or predictable patterns in one or more fiscal quarters, our business is better assessed based on annual results.

The higher than normal emergency response and environmental services revenue in the nine months ended September 30, 2025 was primarily driven by one large emergency response project. Demand for environmental emergency response services remains difficult to predict and as a result, revenues and earnings in the current and prior years, or specific quarters or year-to-date periods within a given year, may not be indicative of future results, making those periods particularly difficult comparisons for future periods. Earnings volatility is also driven by the timing of large projects, particularly in our Remediation and Reuse segment, and the impact of acquisitions. As a result of these factors, and because demand for environmental services is not driven by specific or predictable patterns in one or more fiscal quarters, our business is better assessed based on annual results.

Liquidity describes the ability of a company to generate sufficient cash flows to meet the cash requirements of its business operations, including working capital needs, debt service, acquisitions, other commitments and contractual obligations.

Liquidity describes the ability of a company to generate sufficient cash flows to meet the cash requirements of its business operations, including working capital needs, debt service, acquisitions, other commitments and contractual obligations.

Previous wording
Our principal sources of liquidity have been borrowings under our credit facilities, other borrowing arrangements, proceeds from the issuance of common and preferred stock and cash generated by operating activities. Historically, we have financed our operations and acquisitions from a combination of cash generated from operations, periodic borrowings under senior secured credit facilities, and proceeds from the issuance of common and preferred stock. Our primary cash needs are for day to day operations, to fund working capital requirements, to fund our acquisition strategy and any related cash earn-out obligations, to pay interest and principal on our indebtedness and to make capital expenditures. Historically, our cash needs also included the payment of dividends on our Series A-2 preferred stock. Additionally, in connection with certain acquisitions, we agree to earn-out provisions and other purchase price adjustments that may require future payments. We may make up to $24.6 million in aggregate earn-out payments between the years 2025 and 2027 in connection with the acquisitions of Sensible, Vandrensning, Epic, Spirit and Origins, of which up to $11.5 million may be paid only in cash, up to $2.8 million may be paid only in common stock and up to $10.3 million may be paid in cash or, at our option, in common stock. See Note 7 to our unaudited condensed consolidated financial statements included in Part 1, Item 1. “Financial Statements.” As of June 30, 2025, we had $232.3 million available under the 2025 Credit Facility (without giving effect to any outstanding letters of credit, and subject to borrowing base limitations), and $10.5 million of cash on hand. In April and July 2025, we redeemed the remaining $122.2 million in aggregate stated value of the outstanding Series A-2 Preferred Stock using cash and borrowings under our revolving line of credit.
