• 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.

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.”

Little Rock, Arkansas (May 6, 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 first quarter ended March 31, 2026.
Onterris President and Chief Executive Officer, Vijay Manthripragada, commented, “We delivered first quarter Adjusted EBITDA and margin consistent with our expectations, despite lower revenue, reflecting continued operating efficiency gains. First quarter revenue was impacted by timing-related factors, most notably unseasonably severe winter weather in North America that limited field activity and delayed lab volumes, as well as lower environmental emergency response activity. We view both dynamics as transitory, with underlying demand remaining strong and continuing to grow across our core services. Our full year outlook is unchanged, with performance expected to build through the year. This confidence is supported by recent awards, visibility into our project pipeline and continued operational discipline."
