Onterris, Inc.

What they do

Onterris operates through two reportable segments: Consulting and Treatment (environmental consulting, engineering, and implementation services) and Measurement and Analysis (environmental testing and laboratory services for air, water, and soil). The company also provides environmental emergency response and related recovery services, which are part of the Consulting and Treatment segment. Services span the full lifecycle of client environmental objectives from assessment and compliance to monitoring and remediation.

Revenue drivers

• Consulting and Treatment Services — This segment provides environmental consulting, engineering, and remediation implementation. It includes emergency response work, which is a significant but volatile revenue contributor. For 2026, management guided a $35-$45 million reduction in emergency response revenue from prior expectations.
• Measurement and Analysis — This segment offers environmental testing and laboratory services. Management describes it as relatively predictable and a source of underlying business growth. It likely generates a steady revenue base, though specific segment revenue figures are not disclosed.
• Pass-Through Revenue — Revenue generated on subcontractor and non-labor direct costs. Management guided a $35-$55 million reduction in 2026 pass-through revenue compared to prior expectations, indicating a material component of total revenue.

Recent performance

For Q2 2026, revenue was $186.7 million, down from $234.5 million a year ago, primarily due to historically low environmental emergency response activity. Net income attributable to common stockholders was $1.4 million ($0.04 diluted EPS) versus $18.4 million ($0.42 EPS) in Q2 2025. Adjusted EBITDA was $31.9 million (17.1% of revenue) compared to $39.6 million (16.9% of revenue) in the prior-year quarter. Full-year 2025 revenue was $830.5 million with a net loss of $843,000, and operating cash flow was $107.5 million.

Strategy

Management emphasizes cost discipline and margin expansion, aiming for 150 basis points of Adjusted EBITDA margin improvement in 2026 despite lower revenue. The company repurchased approximately 1.6 million shares for $30 million in the first half of 2026. Onterris is also pursuing a Board-led strategic review process. The company expects to continue being acquisitive, though no acquisitions closed in the first half of 2026. Management remains focused on converting a greater share of revenue into earnings and cash flow.

Risks

• Low Emergency Response Activity — Environmental emergency response revenue has been significantly below historical levels, directly pressuring top-line results and requiring downward guidance revisions.
• High Debt and Leverage — Long-term debt of $337.8 million against cash of $12.7 million; management targets a year-end 2026 leverage ratio of approximately 2.5x, which limits financial flexibility.
• Acquisition Integration and Contingent Payments — Goodwill and intangibles are significant, and the company faces up to $9.6 million in aggregate earn-out payments through 2027, with integration risks and potential fair-value adjustments.
• Cyclical and Event-Dependent Demand — Demand for environmental services, especially emergency response, depends on difficult-to-predict natural or manmade events, causing revenue fluctuations and customer concentration.

Outlook

For full-year 2026, management revised revenue guidance to $740-$790 million (from $840-$900 million) and Consolidated Adjusted EBITDA guidance to $117-$120 million (from $125-$130 million). Third quarter 2026 revenue is expected to be $190-$210 million with Adjusted EBITDA margin of 17-18%. Management expects 60% of full-year Adjusted EBITDA to convert to operating cash flow and year-end leverage of approximately 2.5x, with guidance excluding any benefit from future acquisitions or unoccurred environmental emergencies.
