Onterris.com 2 Press Release expansion compared to 2025 and 50 basis points above the Company's original guidance, given successful ongoing cost optimization. • Despite lower revenue, 2026 operating cash flow expectations are largely unchanged. The Company expects to convert 60.0% of full-year Consolidated Adjusted EBITDA1 into operating cash flow and generate $70.0 million to $80.0 million in operating cash flow in the second half of 2026. • Updated 2026 revenue guidance of $740.0 million to $790.0 million, from $840.0 million to $900.0 million. o Reduction driven by lower pass-through revenue (revenue generated on subcontractor and non- labor direct costs) of $35.0 million to $55.0 million, lower emergency response revenue of $35.0 million to $45.0 million, and other lower revenue of $15.0 million to $25.0 million. o The full-year 2026 revenue outlook does not include any benefit from future acquisitions or environmental emergencies which have not yet occurred. • Third quarter 2026 revenue is expected to be $190.0 million to $210.0 million, with Consolidated Adjusted EBITDA1 as a percentage of revenue expected to be 17.0% to 18.0% at the midpoint of the revenue range. • Onterris expects year-end 2026 leverage ratio of approximately 2.5x, consistent with prior year and inclusive of $30.0 million of share repurchases and $10.8 million of contingent consideration payments in the first half of 2026. Little Rock, Arkansas (August 5, 2026) – Onterris, Inc. (the “Company,” “Onterris” or “ONT”) (NYSE: ONT), a global environmental solutions company solving complex challenges for planet and progress, today announced results for the second quarter ended June 30, 2026. Onterris President and Chief Executive Officer, Vijay Manthripragada, commented, “While environmental emergency response activity and related services remain significantly below historical levels, as reflected in our updated 2026 revenue outlook, the underlying business continues to grow. We expect Consolidated Adjusted EBITDA1 growth in 2026 and approximately 150 basis points of margin expansion compared to 2025. Underlying growth in the business and improved profitability explain why full year cash flow expectations are largely unchanged from the start of the year. These expectations are grounded in our relatively predictable testing business and known consulting and treatment projects." Mr. Manthripragada continued, “We remain committed to achieving our long-term goals and are continuing to execute against the priorities within our control, including serving our clients, maintaining cost discipline and converting a greater share of our revenue into earnings and cash flow. That work is strengthening Onterris and supporting our objective of enhancing value for stockholders.” Second Quarter 2026 Results Revenue in the second quarter of 2026 was $186.7 million compared to $234.5 million in the prior-year quarter, a decrease of $47.9 million. The decrease was driven by lower Consulting and Treatment segment revenue of $46.2 million, primarily due to historically low environmental emergency response

Onterris.com 3 Press Release and related recovery service revenues in the current-year quarter compared to an abnormally high prior-year quarter driven by a single environmental event. Environmental emergency response revenue declined by $37.7 million. Measurement and Analysis segment revenue was lower by $1.7 million; despite this decrease there is strong client demand and acceleration into the second half of 2026. Income from operations in the second quarter of 2026 was $6.5 million, compared to $14.9 million in the prior-year quarter. The decrease primarily reflected lower revenue, partially offset by improved project mix and continued cost discipline. Net income in the second quarter of 2026 was $1.4 million, or $0.04 EPS, compared to net income of $18.4 million, or $0.42 EPS, in the prior-year quarter. The decrease in net income primarily reflected lower operating income and lower fair-value gain on financial instruments, partially offset by lower income tax expense. The $0.38 comparative period decline in EPS was due to lower net income, partially offset by the elimination of the Series A-2 dividend following full redemption of the shares on July 1, 2025, and a lower diluted weighted-average share count. Adjusted Net Income1 and Adj EPS1 in the second quarter of 2026 were $19.6 million and $0.51, respectively, compared to $27.4 million and $0.60, respectively, in the prior-year quarter. Adjusted Net Income1 decreased primarily due to lower revenues in the current period. The decrease in Adj EPS1 in the current period was partially offset by the elimination of the Series A-2 dividend and a lower fully diluted weighted-average share count. Consolidated Adjusted EBITDA1 in the second quarter of 2026 was $31.9 million, or 17.1% of revenue, compared to $39.6 million, or 16.9% of revenue, in the prior-year quarter. The decrease in Consolidated Adjusted EBITDA1 was primarily due to historically low emergency response and related recovery service revenues. Consolidated Adjusted EBITDA1 as a percentage of revenue improved due to successful ongoing cost optimization. Cash Flow, Liquidity and Capital Resources 2026 operating cash flow expectations are largely unchanged. Onterris expects to convert 60.0% of full-year Consolidated Adjusted EBITDA1 into operating cash flow and generate $70.0 million to $80.0 million in operating cash flow in the second half of 2026. Given consistent annual cash flow, Onterris expects a year-end 2026 leverage ratio of approximately 2.5x, consistent with prior year and inclusive of $30.0 million of share repurchases and $10.8 million of contingent consideration payments in the first half of 2026. Net cash used in operating activities for the six months ended June 30, 2026, was $5.5 million, compared to net cash provided by operating activities of $27.4 million in the prior-year period. This $32.9 million decrease primarily reflected lower earnings before non-cash items and higher seasonal working capital usage, including the payment of $27.7 million in first quarter 2026 for accrued annual 2025 bonuses due to financial outperformance, compared to $11.7 million paid for bonuses in the prior year. As of June 30, 2026, Onterris reported a leverage ratio under the 2025 Credit Facility of 3.2x, inclusive of $30.0 million of share repurchases and $10.8 million of contingent consideration payments in the first

Board-led Strategic Review Process The Onterris Board regularly evaluates opportunities to enhance stockholder value. Today, the Company announced a comprehensive Board-led strategic review, with the assistance of outside financial and legal advisors, of the Company’s business, portfolio, capital allocation, long-range strategic plan, and strategic alternatives. These alternatives include, among others, evaluating acquisition interest in the Company and other value-creating transactions (including acquisition opportunities), as well as evaluating operational initiatives and the continued execution of its standalone plan. The Board has not set a timetable for the conclusion of its review, and there can be no assurance that the review will result in any transaction or other outcome. Onterris does not intend to comment further regarding the review unless and until it determines that further disclosure is appropriate or necessary. Limited-Duration Rights Plan The Board also approved the adoption of a limited-duration stockholder rights plan (the “Rights Plan”) in response to significant and undisclosed accumulation of Onterris shares and derivative securities. The Rights Plan is intended to protect the best interests of all Onterris stockholders and the value of their investment, including by safeguarding the integrity of the Board-led strategic review process announced above. The Rights Plan is designed to reduce the likelihood that any person or group prevents Onterris stockholders from realizing the long-term value of their investment by acquiring negative or actual control without appropriately compensating the Company’s stockholders. It is also intended to afford the Board sufficient time and opportunity to make informed judgments that are in the best interests of the Company and all Onterris stockholders. The Rights Plan is effective immediately and has a one-year duration, expiring on August 4, 2027. The Board may consider an earlier termination of the Rights Plan as circumstances warrant. Further details about the Rights Plan will be contained in a Form 8-K to be filed by the Company with the Securities and Exchange Commission.

Onterris.com 11 Press Release 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 Adj EPS represents Adjusted Net Income attributable to stockholders divided by the weighted average number of shares of common stock outstanding during the applicable period. 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. Free cash flow is defined as the sum of net cash provided by (used in) operating activities and net cash used in investing activities, adjusted for the impact of certain other items, including contingent consideration and other purchase price true ups, minority investments, cash paid for acquisitions, net of cash acquired, and dividend payments to the Series A-2 holders. 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. Free cash flow is used by management as one of the means by which it assesses cash generation in excess of ongoing capital needs of the business. 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
Page 13
Onterris.com 12 Press Release 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. Free cash flow has certain limitations and should not be considered as an alternative to or in isolation from net cash provided by (used in) operating activities or any other measure of cash flow generation calculated in accordance with GAAP. In evaluating Free cash flow, you should be aware that Free cash flow does not represent residual cash flow available for discretionary expenditures. Additionally, we have provided estimates regarding Consolidated Adjusted EBITDA for 2026. 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, and fair value changes. 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.
