\n| \n \n(1)<\/p>\n<\/td>\n | | \n\n \nConsolidated 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.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n Full Year 2025 Outlook<\/b><\/p>\n \nThe Company announced an increase in the expected full-year 2025 Consolidated Adjusted EBITDA1<\/sup> 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<\/sup> and revenue outlook does not include any benefit from future acquisitions.<\/p>\nSecond Quarter 2025 Results<\/b><\/p>\n \nRevenue 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.<\/p>\n \nIn 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.<\/p>\n \nIn the second quarter of 2025, Adjusted Net Income1 <\/sup>and Adj EPS1<\/sup> were $27.4 million and $0.63, respectively, compared to the prior year quarter Adjusted Net Income1<\/sup> and Adj EPS1<\/sup> of $10.8 million and $0.20, respectively. Both Adjusted Net Income1<\/sup> and Adj EPS1<\/sup> increased primarily due to strong revenue growth, margin expansion, and the Series A-2 redemption, with Adj EPS1<\/sup> in the current period also benefiting from lower dividends on the then outstanding Series A-2.<\/p>\n\nSecond-quarter 2025 Consolidated Adjusted EBITDA1<\/sup> was $39.6 million, compared to $23.3 million in the prior year quarter. The $16.3 million increase in Consolidated Adjusted EBITDA1<\/sup> was primarily due to higher revenue, including higher organic growth, and margin expansion in all three segments. Consolidated Adjusted EBITDA1<\/sup> as a percentage of revenue increased 340 bps to 16.9% primarily due to significant operating performance improvement across all three segments.<\/p>\nFirst Six Months 2025 Results<\/b><\/p>\n \nRevenue 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.<\/p>\n \nIn 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.<\/p>\n \nIn the first six months of 2025, Adjusted Net Income1<\/sup> and Adj EPS1 <\/sup>were $32.7 million and $0.73, respectively, compared to the prior year period Adjusted Net Income1 <\/sup>and Adj EPS1<\/sup> of $19.3 million and $0.37, respectively. Both Adjusted Net Income1<\/sup> and Adj EPS1<\/sup> increased primarily due to strong revenue growth, margin expansion, and the Series A-2 redemption, with Adj EPS1<\/sup> in the current period also benefiting from lower dividends on the then outstanding Series A-2.<\/p>\n\nConsolidated Adjusted EBITDA1<\/sup> 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<\/sup> was primarily due to higher revenue in all three segments. Consolidated Adjusted EBITDA1<\/sup> as a percentage of revenue increased 200 bps to 14.2% primarily due to strong operating performance in the Measurement & Analysis segment.<\/p>\nOperating Cash Flow, Liquidity and Capital Resources<\/b><\/p>\n \nNet 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.<\/p>\n \nAs of June 30, 2025, Montrose\u2019s 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.<\/p>\n \nOn 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.<\/p>\n Webcast and Conference Call<\/b><\/p>\n \nThe Company will host a webcast and conference call on Thursday, August 7, 2025, at 8:30 a.m. Eastern Time to discuss second quarter results.

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.<\/p>\n \nConsolidated 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.<\/p>\n \nThese 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.<\/p>\n \nAdditionally, 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.<\/p>\n \nIn 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.<\/p>\n \nIn 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.<\/p>\n \n\n| \u00a0<\/td>\n<\/tr>\n | \n| \n Montrose Environmental Group, Inc.
