(1)		Consolidated Adjusted EBITDA, Adjusted Net Income (Loss) and Diluted Adjusted Net Income (Loss) per share are non-GAAP measures. See the appendix to this release for a discussion of these measures, including how they are calculated and the reasons why we believe they provide useful information to investors, and a reconciliation for historical periods to the most directly comparable GAAP measures.

Full Year 2025 Outlook

The Company announced an increase in the expected full-year 2025 Consolidated Adjusted EBITDA¹ by $8 million at the midpoint, to a range of $111.0 million to $117.0 million, and the expected full-year 2025 revenue by $45 million at the midpoint, to a range of $795.0 million to $835.0 million. The Consolidated Adjusted EBITDA¹ and revenue outlook does not include any benefit from future acquisitions.

Second Quarter 2025 Results

Revenue in the second quarter of 2025 was $234.5 million compared to $173.3 million in the prior year quarter, an increase of $61.2 million, or 35.3%. This increase was primarily due to incremental revenue from environmental emergency responses of $35.6 million; strong organic revenue growth in all segments totaling $17.1 million; and $9.1 million in contributions from acquisitions. Revenue from environmental emergency responses was $48.5 million in the second quarter of 2025, compared to $12.9 million in the prior year quarter.

In the second quarter of 2025, increased income from operations resulted from strong revenue growth, including organic growth, contributions from acquisitions, and improved margins in all three segments. Net income in the second quarter of 2025 was $18.4 million, or $0.42 EPS, compared to a net loss of $10.2 million, or $0.39 LPS, in the prior year quarter. This $28.5 million year-over-year improvement in net income primarily resulted from revenue growth, including organic growth, margin expansion, and a $10.0 million fair value gain related to the Series A-2 redemption. The $0.81 comparative period increase in EPS was due to strong revenue growth, margin expansion, and the Series A-2 redemption, partially offset by an increase in weighted average diluted common shares outstanding.

In the second quarter of 2025, Adjusted Net Income¹and Adj EPS¹ were $27.4 million and $0.63, respectively, compared to the prior year quarter Adjusted Net Income¹ and Adj EPS¹ of $10.8 million and $0.20, respectively. Both Adjusted Net Income¹ and Adj EPS¹ increased primarily due to strong revenue growth, margin expansion, and the Series A-2 redemption, with Adj EPS¹ in the current period also benefiting from lower dividends on the then outstanding Series A-2.

Second-quarter 2025 Consolidated Adjusted EBITDA¹ was $39.6 million, compared to $23.3 million in the prior year quarter. The $16.3 million increase in Consolidated Adjusted EBITDA¹ was primarily due to higher revenue, including higher organic growth, and margin expansion in all three segments. Consolidated Adjusted EBITDA¹ as a percentage of revenue increased 340 bps to 16.9% primarily due to significant operating performance improvement across all three segments.

First Six Months 2025 Results

Revenue in the first six months of 2025 was $412.4 million, compared to $328.7 million in the prior year period, an increase of $83.7 million, or 25.5%. This increase was primarily due to incremental revenue from environmental emergency responses of $33.8 million; strong organic revenue growth in all three segments totaling $28.4 million; and $22.5 million in contributions from acquisitions. Revenue from environmental responses was $62.4 million in the first six months of 2025, compared to $28.6 million in the prior year period.

In the first six months of 2025, higher income from operations resulted from strong revenue growth, including organic growth, contributions from acquisitions, operating leverage. Net loss in the first half of 2025 was $1.0 million, or $0.15 LPS, compared to a net loss of $23.5 million, or $0.91 LPS, in the prior year period. This $22.5 million year-over-year improvement in net loss primarily resulted from revenue growth, including strong organic growth, margin expansion, and a $9.7 million fair value gain related to the Series A-2 preferred stock redemption, partially offset by incremental interest and tax expenses. The $0.77 comparative period improvement in LPS primarily resulted from revenue growth, margin expansion, and the Series A-2 redemption, partially offset by an increase in weighted average diluted common shares outstanding.

In the first six months of 2025, Adjusted Net Income¹ and Adj EPS¹were $32.7 million and $0.73, respectively, compared to the prior year period Adjusted Net Income¹and Adj EPS¹ of $19.3 million and $0.37, respectively. Both Adjusted Net Income¹ and Adj EPS¹ increased primarily due to strong revenue growth, margin expansion, and the Series A-2 redemption, with Adj EPS¹ in the current period also benefiting from lower dividends on the then outstanding Series A-2.

Consolidated Adjusted EBITDA¹ for the first six months of 2025 was $58.6 million, compared to $40.2 million in the prior year period. The $18.4 million increase in Consolidated Adjusted EBITDA¹ was primarily due to higher revenue in all three segments. Consolidated Adjusted EBITDA¹ as a percentage of revenue increased 200 bps to 14.2% primarily due to strong operating performance in the Measurement & Analysis segment.

Operating Cash Flow, Liquidity and Capital Resources

Net cash provided by operating activities for the six months ended June 30, 2025, was $27.4 million compared to cash used in operating activities of $21.1 million in the prior year period. This $48.5 million improvement was primarily due to an increase in earnings before non-cash items of $22.5 million and improved working capital performance with a $21.9 million reduction in cash outflow. Cash flow in full-year 2025 is expected to increase significantly versus the prior year.

As of June 30, 2025, Montrose's leverage ratio under the 2025 Credit Facility was 2.5x. As of June 30, 2025 Montrose had $242.8 million of available liquidity, including $10.5 million of cash and $232.3 million of availability on its revolving line of credit.

On July 1, 2025, the Company voluntarily fully redeemed all remaining issued and outstanding shares of Series A-2 held by an affiliate of Oaktree Capital. The Company used cash on hand and borrowings under its 2025 Credit Facility to redeem the outstanding stated value of Series A-2 Preferred Stock of $62.2 million and to pay $1.4 million of accrued and unpaid dividends thereon through the redemption date. Giving pro forma effect for the final redemption payment, the Company's leverage ratio was 2.99x.

Non-GAAP Financial Information

In addition to our results under GAAP, in this release we also present certain other supplemental financial measures of financial performance that are not required by, or presented in accordance with, GAAP, including, Consolidated Adjusted EBITDA, Adjusted Net Income and Basic and Diluted Adj EPS. We calculate Consolidated Adjusted EBITDA as net income (loss) before interest expense, income tax expense (benefit) and depreciation and amortization, adjusted for the impact of certain other items, including stock-based compensation expense and acquisition-related costs, as set forth in greater detail in the table below. We calculate Adjusted Net Income as net income (loss) before amortization of intangible assets, stock-based compensation expense, fair value changes to financial instruments and contingent earnouts, discontinued specialty lab, and other gain or losses, as set forth in greater detail in the table below. Basic and Diluted Adj EPS represents Adjusted Net Income attributable to stockholders divided by the fully diluted number of shares of common stock outstanding during the applicable period.

Consolidated Adjusted EBITDA is one of the primary metrics used by management to evaluate our financial performance and compare it to that of our peers, evaluate the effectiveness of our business strategies, make budgeting and capital allocation decisions and in connection with our executive incentive compensation. Adjusted Net Income and Basic and Diluted Adj EPS are useful metrics to evaluate ongoing business performance after interest and tax. These measures are also frequently used by analysts, investors and other interested parties to evaluate companies in our industry. Further, we believe they are helpful in highlighting trends in our operating results because they allow for more consistent comparisons of financial performance between periods by excluding gains and losses that are non-operational in nature or outside the control of management, and, in the case of Consolidated Adjusted EBITDA, by excluding items that may differ significantly depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which we operate and capital investments.

These non-GAAP measures do, however, have certain limitations and should not be considered as an alternative to net income (loss), earnings (loss) per share or any other performance measure derived in accordance with GAAP. Our presentation of Consolidated Adjusted EBITDA, Adjusted Net Income and Basic and Diluted Adj EPS should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items for which we may make adjustments. In addition, Consolidated Adjusted EBITDA, Adjusted Net Income and Basic and Diluted Adj EPS may not be comparable to similarly titled measures used by other companies in our industry or across different industries, and other companies may not present these or similar measures. Management compensates for these limitations by using these measures as supplemental financial metrics and in conjunction with our results prepared in accordance with GAAP. We encourage investors and others to review our financial information in its entirety, not to rely on any single measure and to view Consolidated Adjusted EBITDA, Adjusted Net Income and Basic and Diluted Adj EPS in conjunction with the related GAAP measures.

Additionally, we have provided estimates regarding Consolidated Adjusted EBITDA for 2025. These projections account for estimates of revenue, operating margins and corporate and other costs. However, we cannot reconcile our projection of Consolidated Adjusted EBITDA to net income (loss), the most directly comparable GAAP measure, without unreasonable efforts because of the unpredictable or unknown nature of certain significant items excluded from Consolidated Adjusted EBITDA and the resulting difficulty in quantifying the amounts thereof that are necessary to estimate net income (loss). Specifically, we are unable to estimate for the future impact of certain items, including income tax (expense) benefit, stock-based compensation expense, fair value changes and the accounting for the Series A-2 Preferred Stock. We expect the variability of these items could have a significant impact on our reported GAAP financial results.

In this release we also reference our organic growth. We define organic growth as the change in revenues excluding revenues from i) our environmental emergency response business, ii) acquisitions for the first twelve months following the date of acquisition, and iii) businesses held for sale, disposed of or discontinued. Management uses organic growth as one of the means by which it assesses our results of operations. Organic growth is not, however, a measure of revenue growth calculated in accordance with U.S. generally accepted accounting principles, or GAAP, and should be considered in conjunction with revenue growth calculated in accordance with GAAP. We have grown organically over the long term and expect to continue to do so.

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.

(1)		Represents amortization of intangible assets.
(2)		Represents non-cash stock-based compensation expenses related to (i) option awards issued to employees, (ii) restricted stock grants issued to directors and selected employees, (iii) and stock appreciation rights grants issued to selected employees. As of December 31, 2024, the performance-based stock appreciation rights granted to the Company's management in 2021 were cancelled and therefore, not included in the stock-based compensation expenses thereafter.
(3)		Includes financial and tax diligence, consulting, legal, valuation, accounting and travel costs and acquisition-related incentives related to our acquisition activity, including direct costs of integration.
(4)		Amounts relate to the change in fair value of the interest rate swap instruments and the embedded derivative attached to the Series A-2 preferred stock.
(5)		Amounts represent non-capitalizable expenses associated with refinancing and amending our debt facilities.
(6)		Amounts reflect the difference between the expected settlement value of acquisition related earn-out payments at the time of the closing of acquisitions and the expected (or actual) value of earn-outs at the end of the relevant period.
(7)		Amounts consist of operating losses before depreciation related to the Discontinued Specialty Lab.
(8)		Amounts for the three and six months ended June 30, 2025 consist primarily of non-recurring costs incurred to restructure the Company's renewable energy business, third party expenses associated with the independent review and analysis of assertions in a short seller report regarding the Company, and costs to centralize certain back-office functions. Amounts for the three and six months ended June 30, 2024 consist of costs associated with a lease abandonment.
(9)		The Company applied the estimated effective tax rate on portions of the adjustments related to our significant foreign entities, and determined the US portion of the adjustments do not have any tax impact since we are in a full deferred tax asset valuation allowance as of June 30, 2025.
(10)		Represents Adjusted Net Income attributable to stockholders divided by the weighted average number of shares of common stock outstanding.
(11)		Represents Adjusted Net Income attributable to stockholders divided by fully diluted number of shares of common stock.
(12)		The fully diluted share count increased year-over-year primarily due to a higher number of share equivalents related to the Series A-2 Preferred Stock due to lower common stock share price of $21.89 as of June 30, 2025, compared to $44.56 as of June 30, 2024, causing a higher conversion rate from the A-2 Preferred Stock to common shares.
