The Three And Six Months Ended June 30, 2025 Compared to the Three And Six Months Ended June 30, 2024

Current report

Revenue for the six months ended June 30, 2025 increased $83.7 million or 25.5% as compared to the six months ended June 30, 2024. The increase was primarily driven by a $33.8 million higher emergency response revenue, strong organic growth of $28.4 million across all three segments, and $22.5 million of additional revenue from acquisitions. Revenue from environmental response was $62.4 million in the six months ended June 30, 2025 compared to $28.6 million in the six months ended June 30, 2024.

Current report

Cost of revenues for the six months ended June 30, 2025 compared to the six months ended June 30, 2024 increased by $40.6 million or 20.2% driven primarily by the increase in revenues. Cost of revenues as a percentage of revenue for the six months ended June 30, 2025 was 58.5%, compared to 61.1% for the six months ended June 30, 2024. This improvement was a result of similar drivers as those in the three months ended June 30, 2025.

Current report

Selling, general and administrative expense for the three months ended June 30, 2025 compared to the three months ended June 30, 2024 increased $14.4 million or 24.4% primarily due to an increase of $8.9 million in labor costs, mainly driven by a $6.0 million increase in bonus accrual as a result of better than expected performance in the second quarter, and a $4.8 million increase in bad debt expense primarily driven by aged receivables from the City of Tustin. Selling, general and administrative expense as a percentage of revenues decreased to 31.4% from 34.2% in the comparable period.

Current report

Selling, general and administrative expense for the six months ended June 30, 2025 compared to the six months ended June 30, 2024 increased $23.6 million or 20.3% primarily due to an increase of $14.9 million in labor costs mainly driven by a $7.9 million increase in bonus accrual, and a $6.1 million increase in bad debt expense, driven by the same factor described above. Selling, general and administrative expense as a percentage of revenues decreased to 33.9% from 35.4% in the comparable period.

Current report

Other income (expense), net for the six months ended June 30, 2025 was comprised of a fair value gain of $9.7 million related to the Series A-2 preferred stock conversion option, partially offset by losses of $1.6 million related to a fair value adjustment on our interest rate swaps. Other income (expense), net for the six months ended June 30, 2024 was comprised of losses related to fair value adjustments on the Series A-2 preferred stock conversion option of $0.6 million and on our interest rate swaps of $0.4 million, partially offset by $0.5 million of other non-operating income.

Current report

The income tax expense for the three months ended June 30, 2025 decreased compared to the three months ended June 30, 2024 primarily as a result of the tax expense having previously been recorded as of Q1 2025 as a result of an overall increase in pretax book income compared to that recorded as of June 30, 2024.

Current report

The income tax expense for the six months ended June 30, 2025 increased compared to the six months ended June 30, 2024 primarily as a result of an overall increase in the net deferred tax liability recorded as of June 30, 2025 relative to June 30, 2024, in addition to an increase in pretax book income as of June 30, 2025 relative to June 30, 2024.

Current report

The Three And Six Months Ended June 30, 2025 Compared to the Three And Six Months Ended June 30, 2024

Current report

Assessment, Permitting and Response segment revenues for the three and six months ended June 30, 2025 increased compared to the three and six months ended June 30, 2024 due to an increase in revenues from environmental emergency responses of $35.6 million and $33.8 million, respectively, organic growth within our non-response consulting and advisory services of $12.0 million and $5.4 million, respectively, and $2.8 million and $5.8 million, respectively, from acquisitions.

Current report

Remediation and Reuse segment revenues for the three and six months ended June 30, 2025 increased compared to the three and six months ended June 30, 2024, as a result of organic growth of $0.2 million and $9.6 million, respectively, and additional revenue from acquisitions of $2.5 million and $7.6 million, respectively.

Current report

Measurement and Analysis Segment Adjusted EBITDA, for the three and six months ended June 30, 2025 increased compared to the three and six months ended June 30, 2024 as a result of higher revenues driven by organic growth and higher Segment Adjusted EBITDA margin driven by the benefits of improved operating performance.

Current report

Remediation and Reuse Segment Adjusted EBITDA for the three and six months ended June 30, 2025 increased compared to the three and six months ended June 30, 2024 due to higher revenues.

Current report

Corporate and other costs for the three and six months ended June 30, 2025 when compared to the three and six months ended June 30, 2024 increased primarily due to higher bonus accrual of $5.1 million and $6.0 million, respectively, driven in part by an outperformance in the second quarter of 2025, as well as higher outside service costs of $0.9 million related to an IT migration, and, in the three months ended June 30, 2025, the timing of audit expenses.

Current report

Working capital increased by $48.1 million in the six months ended June 30, 2024, primarily due to an increase in account receivable of $38.0 million and a $7.9 million decrease in accrued payroll.

Current report

For the six months ended June 30, 2024, net cash provided by financing activities was $102.8 million. Cash provided by financing activities was driven by net proceeds from the issuance of common stock through a public offering of $121.8 million, proceeds from the issuance of an additional term loan of $50.0 million and proceeds from the exercise of stock options of $1.4 million, partially offset by a partial redemption of the Series A-2 preferred stock of $60.0 million, dividends on the Series A-2 preferred stock of $5.6 million, and aggregate repayments made on our term loan, finance leases and aircraft loan of $7.5 million.

Current report

On May 7, 2025, the Company announced that its Board of Directors has approved a stock repurchase program of up to $40.0 million. The repurchase program does not have a set expiration date. The Company did not make any stock repurchases in the three months ended June 30, 2025.

Previous report

Selling, general and administrative expense for the three months ended March 31, 2025 compared to the three months ended March 31, 2024 increased $9.2 million or 16.0%. Acquisitions contributed $2.6 million to this increase with the balance primarily attributable to higher labor costs of $5.7 million, higher bad debt expense of $1.3 million and higher stock-based compensation of $1.1 million.

Previous report

The income tax expense for the three months ended March 31, 2025 increased compared to the three months ended March 31, 2024 primarily as a result of certain tax inclusions from foreign acquisitions in 2024 and an increase in U.S. current federal tax expense as a result of the Company having previously utilized all pre-2018 net operating loss carryforwards that were available to offset 100% of taxable income, and therefore currently utilizing post-2017 net operating loss carryforwards which are limited to offsetting 80% of taxable income in any given year. The income tax expense is primarily related to operations in the United States, Canada and Australia.

Previous report

Assessment, Permitting and Response segment revenues for the three months ended March 31, 2025 decreased compared to the three months ended March 31, 2024 due to a decline in revenues from environmental emergency responses of $1.8 million and a decrease of $6.6 million due to several larger projects in the prior year quarter that did not repeat in the current year, partially offset by the impact of an acquisition, which contributed $3.0 million to the increase in the three months ended March 31, 2025 .

Previous report

Remediation and Reuse segment revenues for the three months ended March 31, 2025 increased compared to the three months ended March 31, 2024, primarily driven by strong demand for our treatment technologies solutions, and contributions from acquisitions. Specifically, organic growth contributed $9.3 million, and acquisitions contributed $5.1 million to the increase in revenues in the three months ended March 31, 2025.

Previous report

Assessment, Permitting and Response Segment Adjusted EBITDA and Segment Adjusted EBITDA margin for the three months ended March 31, 2025 decreased compared to the three months ended March 31, 2024 primarily due to a reduction in higher margin emergency response revenues, lower revenues from several high margin projects in the prior year quarter that did not repeat in the current year, and project mix.

Previous report

Measurement and Analysis Segment Adjusted EBITDA and Segment Adjusted EBITDA margin for the three months ended March 31, 2025 increased compared the three months ended March 31, 2024 primarily due to the operating leverage across all business lines driven by significantly higher revenue, as well as the benefit from acquisitions.

Previous report

Corporate and other costs for the three months ended March 31, 2025 increased $0.4 million primarily due to higher labor costs to support the increase in revenues. Corporate and other costs fell to 6.3% of revenue from 7.0% of revenue as a result of operating leverage and the timing of certain expenses.

Previous report

Working capital increased by $30.0 million in the three months ended March 31, 2024, primarily due to a decrease in accrued payroll and benefits of $10.0 million, due primarily to the payment of bonuses in the first quarter, an increase in accounts receivable and contract assets of $9.1 million, due in part to integration-related invoicing delays and collection delays on a single large government project, a seasonal decrease in accounts payable and other accrued liabilities of $7.8 million, and an increase in prepaid expenses and other current assets of $2.5 million.

Previous report

For the three months ended March 31, 2024, net cash provided by financing activities was $73.3 million. Cash provided by financing activities was driven by borrowing under our credit facility of $216.9 million, partially offset by repayments of borrowing of $82.3 million, and by the repayment on the Series A-2 preferred stock of $60.0 million.

As a result of our acquisitions, goodwill and other intangible assets represent a significant proportion of our total assets, and amortization of intangible assets has historically been a significant expense. Our historical financial statements also include other acquisition-related costs, including costs relating to external legal support, diligence and valuation services and other transaction and integration-related matters. 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

Our segments and our business lines within each segment generate different levels of profitability and, accordingly, shifts in the mix of revenues between segments can impact our consolidated reported net income, net loss margin, Segment Adjusted EBITDA and Segment Adjusted EBITDA margin from quarter to quarter and year to year. Inter-company revenues between business lines within segments have been eliminated. See Note 19 to our unaudited condensed consolidated financial statements included in Part 1, Item 1 “Financial Statements.”

Previous wording

Our revenues and certain expenses, including selling, general and administrative expense, vary from period to period due primarily to changes in organic growth, the incremental contribution from recent acquisitions and strategic decisions we may make from time to time. When we refer to changes driven by organic growth, we are referring to the contribution from businesses that have been part of Montrose for more than 12 months, with certain limited exclusions as discussed in greater detail above. In a given reporting period, when we refer to revenue changes driven by acquisitions, we are referring to the revenue contribution from any acquisition from its closing date through the first 12 months of that acquisition, at which point any subsequent contribution therefrom would be organic.

Previous wording

Total debt at March 31, 2025 was $241.8 million net of deferred debt issuance costs, which was an increase of $19.1 million compared to December 31, 2024. The increase is primarily driven by the refinanced term loan in connection with the 2025 Credit Facility, which increased the aggregate amount outstanding by approximately $10.8 million, and additional usage of our revolving line of credit, under which borrowings increased by $9.7 million. This increase was partially offset by repayments and amortization of the various debt noted.

Current wording

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.

Previous wording

Interest expense, net was $5.1 million in the three months ended March 31, 2025 and $3.3 million in the three months ended March 31, 2024. We expect interest expense to remain a significant cost as we continue to leverage our credit facility to support our operations and future acquisitions.

Current wording

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 expect interest expense to remain a significant cost as we continue to leverage our credit facility to support our operations and future acquisitions.

Previous wording

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. Additionally, due to the field-based nature of certain of our services, weather patterns generally impact our field-based teams’ ability to operate in the winter months. As a result, our operating results in our Measurement and Analysis segment and our Remediation and Reuse segment, experience some quarterly variability with generally lower revenues and lower earnings in the first and fourth quarters and typically we experience higher overall revenues and earnings in the second and third quarters. As we continue to grow and expand into new geographies and service lines, quarterly variability in our Measurement and Analysis and Remediation and Reuse segments may deviate from historical trends.

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 $13.9 million and $15.7 million for the three months ended March 31, 2025 and 2024, 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 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.

Current 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.

Previous wording

Revenue for the three months ended March 31, 2025 increased $22.5 million or 14.5% as compared to the three months ended March 31, 2024. The increase was primarily comprised of organic growth in the Remediation and Reuse and Measurement and Analysis segments of $17.8 million, and contribution from acquisitions of $13.5 million, partially offset by $5.8 million reduction in the Assessment, Permitting and Response segment revenue, due to several larger projects that were performed in the prior year quarter that did not repeat in the current year, and a $1.8 million reduction in environmental emergency response service revenues. Environmental emergency response revenues were $13.9 million and $15.7 million in the three months ended March 31, 2025 and 2024, respectively.

Current wording

Revenue for the three months ended June 30, 2025 increased $61.2 million or 35.3% as compared to the three months ended June 30, 2024. The increase was primarily driven by $35.6 million higher emergency response revenue, strong organic growth of $17.1 million driven primarily by the Assessment, Permitting and Response and Measurement and Analysis segments, and $9.1 million of additional revenue from acquisitions. Environmental emergency response revenues were $48.5 million in the three months ended June 30, 2025, compared to $12.9 million in the three months ended June 30, 2024.

Previous wording

Cost of revenues for the three months ended March 31, 2025 compared to the three months ended March 31, 2024 increased primarily due to the increase in revenues. Cost of revenues as a percentage of revenue for the three months ended March 31, 2025 was 61.0%, compared to 62.2% for the three months ended March 31, 2024. This percentage decrease was driven primarily by operating leverage across all business lines within our Measurement and Analysis businesses, and improved margins in our treatment technology business.

Current wording

Cost of revenues for the three months ended June 30, 2025 compared to the three months ended June 30, 2024 increased by $28.7 million or 27.6% driven primarily by the increase in revenues. Cost of revenues as a percentage of revenue for the three months ended June 30, 2025 was 56.6%, compared to 60.1% for the three months ended June 30, 2024. This improvement was driven primarily by high margin emergency response revenues in our Assessment, Permitting and Response segment and operating leverage across all business lines within our Measurement and Analysis businesses.

Previous wording

The increase in depreciation of property and equipment and the amortization of intangible assets and finance leases were primarily driven by an increase of $1.0 million in amortization of intangible assets during the three months ended March 31, 2025 compared to the three months ended March 31, 2024. See Note 8 to our unaudited condensed consolidated financial statements included in Part 1, Item 1. “Financial Statements.”

Current wording

The increase in depreciation of property and equipment and the amortization of intangible assets and finance leases in both the three and six months ended June 30, 2025 was primarily driven by higher property and equipment balances during the applicable periods. See Notes 5 and 6 to our unaudited condensed consolidated financial statements included in Part 1, Item 1. “Financial Statements.”

Previous wording

Other (expense) income, net for the three months ended March 31, 2025 was comprised of losses of $0.9 million related to a fair value adjustment on our interest rate swaps and a $0.3 million charge related to a fair value adjustment on the Series A-2 Preferred Stock conversion option, partially offset by $0.4 million of other income. Other (expense) income, net for the three months ended March 31, 2024 was mainly comprised of income of $0.3 million related to a fair value adjustment on our interest rate swaps and $0.2 million of other income.

Current wording

Other income (expense), net for the three months ended June 30, 2025 was comprised of a fair value gain of $10.0 million related to the Series A-2 preferred stock conversion option, partially offset by losses of $0.7 million related to a fair value adjustment on our interest rate swaps. Other income (expense), net for the three months ended June 30, 2024 was comprised of losses related to fair value adjustments on our interest rate swaps of $0.7 million and the Series A-2 preferred stock conversion option of $0.5 million, partially offset by $0.3 million of other non-operating income.

Previous wording

Interest expense, net for the three months ended March 31, 2025 increased primarily as a result of higher average debt balances and a loss of $0.9 million related to the write-off of unamortized debt issuance costs upon repayment of the 2021 Credit Facility in February 2025.

Current wording

Interest expense, net for the three and six months ended June 30, 2025 and 2024 increased primarily as a result of higher interest rates and higher debt balances. Interest expense in the six months ended June 30, 2025 was also impacted by the write off of deferred debt issuance costs of $0.9 million as a result of the refinancing of our senior credit facility in February 2025.

Previous wording

Weighted average interest rates as of March 31, 2025 and March 31, 2024 were 6.3% and 7.3%, respectively. See “—Key Factors that Affect Our Business and Our Results—Financing Costs” and Notes 12 and 13 to our unaudited condensed consolidated financial statements included in Part I, Item 1. “Financial Statements.”

Current wording

Weighted average interest rates as of June 30, 2025 and June 30, 2024 were 6.2% and 7.4%, respectively. See “—Key Factors that Affect Our Business and Our Results—Financing Costs” and Notes 12 and 13 to our unaudited condensed consolidated financial statements included in Part I, Item 1. “Financial Statements.”

Previous wording

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 dividends on our Series A-2 Preferred Stock, and to make capital expenditures. 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 $26.7 million in aggregate earn-out payments between the years 2025 and 2027 in connection with the acquisitions of Sensible, Vandrensning, Epic, 2DOT, Spirit and Origins, of which up to $12.0 million may be paid only in cash, up to $2.8 million may be paid only in common stock and up to $11.9 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 March 31, 2025, we had $263.9 million available under the 2025 Credit Facility (without giving effect to any outstanding letters of credit, and subject to borrowing base limitations), and $30.3 million of cash on hand. In April 2025, we redeemed $60.0 million in aggregate stated value of the outstanding Series A-2 Preferred Stock using cash and borrowings under our revolving line of credit.
