The Three and Nine Months Ended September 30, 2026 Compared to the Three and Nine Months Ended September 30, 2025
Current report
Revenue for the three months ended September 30, 2026 decreased $21.8 million or 9.7% as compared to the three months ended September 30, 2025. The decrease was driven by a significant environmental response event in the prior year that generated $45.4 million of revenues, which did not recur in the current year, and lower Measurement and Analysis revenues of $1.9 million, partially offset by $25.5 million of higher emergency response, core consulting, recovery, and treatment revenues excluding the impact of the single event in the prior year.
Current report
Revenue for the nine months ended September 30, 2026 decreased $79.0 million or 12.4% as compared to the nine months ended September 30, 2025. The decrease was primarily driven by a significant environmental response event in the prior year that generated $99.0 million of revenues, which did not recur in the current year, and lower Measurement and Analysis revenues of $8.7 million, partially offset by $28.8 million of higher emergency response, core consulting, and recovery revenues excluding the impact of the single event in the prior year.

Historically, the Company had three business segments—Assessment, Permitting and Response, Measurement and Analysis and Remediation and Reuse. Effective in the first quarter of 2026, we realigned two of our reportable segments to reflect updates made to our organizational structure and operating model. As a result of these changes, we aggregated the Assessment, Permitting and Response and Remediation and Reuse segments into a newly created Consulting and Treatment segment. The Company's Measurement and Analysis and corporate segments were not affected by the realignment.

Although we did not consummate any acquisitions in the three and six months ended June 30, 2026, or the year ended 2025, we have been, and expect to continue to be, an acquisitive company.

Although we did not consummate any business acquisitions as defined in the relevant accounting guidance in the three and nine months ended September 30, 2026, or the year ended December 31, 2025, we entered into an asset purchase agreement to acquire certain assets, including customer contracts, on September 15, 2026, for a purchase price of $5.1 million, and expect to continue to be, an acquisitive company.

In addition, in any year gains and losses from changes in the fair value of business acquisition contingencies such as earn-outs could be significant.

Previous wording
In addition to the impact of seasonality on earnings, our environmental 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 $10.8 million and $48.5 million for the three months ended June 30, 2026 and 2025, respectively, and $18.9 million and $62.4 million for the six months ended June 30, 2026 and 2025, respectively. Demand for environmental emergency response services remains difficult to predict and as a result, we may have experienced revenues and earnings in prior years that are not 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 Consulting and Treatment 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.

In addition to the impact of seasonality on earnings, our environmental 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.

Our principal sources of liquidity have been cash generated by operating activities, borrowings under our senior secured credit facilities, other borrowing arrangements, and proceeds from the issuance of common stock. 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 and, more recently, we have begun repurchasing shares of common stock pursuant to our share repurchase program. 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 $7.0 million in aggregate earn-out payments between the years 2026 and 2027 in connection with certain of our acquisitions of which up to $3.8 million may be paid only in cash, up to $2.8 million may be paid only in common stock and up to $0.4 million may be paid in cash or, at our option, in common stock.
