What Moved Onterris (Up 32.71% in 1W)

Onterris, an environmental services company, closed the screener snapshot at USD 18.93 after a 17.33% latest session gain on top of a 32.71% weekly rise. The shares were USD 14.87 on October 26, 2026, so the climb is about 27.3% from that level (calculated). The November 4, 2026 release showed third quarter revenue of USD 203.0 million, down from USD 224.9 million because a USD 45.4 million emergency recovery event inflated the prior year. Excluding it, revenue rose about USD 23.6 million, or 13.1%. Net service revenue was USD 162.5 million versus USD 160.5 million, and diluted EPS was USD 0.24 versus USD 0.21.

Why Re-Rating Happens in a Stock Like This

The catalyst is a combination of an Earnings beat on margins, reiterated guidance and an open strategic review. The company said it has engaged with a number of strategic and financial parties, advised by Evercore, AEC Advisors and Kirkland and Ellis, and the board has set no timetable. No outcome is assured. Consensus adjusted EPS in the second quarter was USD 0.38 against USD 0.51 reported, while revenue of USD 186.7 million missed USD 199.31 million, so the market has rewarded profit over sales. Guidance implies at least 150 basis points of Margin expansion versus 2025 and 60.0% conversion of adjusted EBITDA into operating cash flow. The Earnings Call was set for November 5, 2026 at 8:30 a.m. ET.

Valuation, Liquidity and Risks After a Run

The 52-week range was USD 12.26 to USD 30.00 on October 26, 2026, when Market Value was USD 522.20 million on 35.12 million shares, or about USD 665 million at USD 18.93 (calculated). Trailing twelve month revenue was USD 773.34 million and trailing EPS negative USD 0.31, so no P/E applies. Cash was USD 20.1 million with total liquidity of USD 192.0 million, and Long Term Debt was USD 311.0 million. Analysts were split, with JPMorgan at Neutral with a USD 14 target and a USD 18.20 average. After a 32.71% run, a small number of trades can move the price, spreads can be wide, and a review may end without a deal.

Where Things Stand

Onterris (NYSE:ONT) rose 32.71% in a week on higher margins, reiterated guidance and an ongoing strategic review, not on revenue growth. It sits among the small cap weekly gainers in a published screener snapshot, behind leaders such as Universal Logistics at 83.75%. At USD 18.93 it remains below its USD 30.00 52-week high. Gains can reverse if the review ends without a transaction or the November 5 call disappoints.
