Onterris (NYSE: ONT) received a Defense Innovation Unit Success Memo after completing a prototype project treating PFAS-contaminated groundwater in Pennsylvania. The project at Former Naval Air Station Joint Reserve Base Willow Grove met performance objectives under its Other Transaction Authority agreement. The memo gives federal agencies a pathway to pursue follow-on production and deployment without additional competitive processes; it is not itself a deployment award.
The company's regenerable ion exchange resin technology treated 2.5 million gallons of groundwater to U.S. Environmental Protection Agency drinking water maximum contaminant levels for PFAS over eight months. Three regeneration cycles each restored initial treatment performance. The prototype was selected following a competitive evaluation of 64 submissions.
Onterris (ONT) plans to release its third-quarter fiscal 2026 results on November 4, 2026, after New York Stock Exchange trading closes.
The company plans to discuss the results and forward outlook on a conference call on November 5, 2026, at 8:30 a.m. Eastern Time. A live webcast and webcast replay will be available on its investor website.
Onterris (ONT) advanced to No. 5 among pure-play environmental firms in Engineering News-Record's latest Top 200 Environmental Firms rankings. The company moved up from No. 7 in 2025. Pure-play firms focus on environmental services rather than operating across broader industries.
ENR publishes the rankings annually, evaluating firms based on environmental services revenue and performance across environmental disciplines. The recognition covers Onterris's position among environmental specialists, rather than its position across the entire Top 200 list.
Onterris (ONT) hosted EPA Administrator Lee Zeldin at its Portland, Maine office last week to discuss PFAS drinking-water treatment.
The presentation featured SORBIX RePURE, which uses specialized resins to capture PFAS chemicals from water and regenerates the resins for reuse. Onterris says regeneration can reduce waste and long-term operating costs compared with replacing and disposing of single-use treatment media.
Onterris has sold NSF-certified regenerable resin systems for drinking-water applications in North Carolina and Maine, with additional deployment planned in Ohio. The company is investing in U.S. regeneration capacity and advancing plans for a dedicated U.S. drinking-water media regeneration facility.

Onterris (ONT) has been awarded an environmental services contract worth more than C$9 million for construction of a C$3 billion natural gas transmission project in Canada, with revenue expected through the end of 2027.
The unnamed leading Canadian energy infrastructure company’s project is designed to support growing energy demand and long-term economic development, and once operational is expected to deliver more than 1 billion cubic feet of natural gas per day. Onterris previously supported earlier engineering phases, and this award extends its role into construction, interim reclamation, and final clean-up activities.
Scope includes wildlife and aquatic habitat protection, wetlands and vegetation management, contamination response, invasive species control, regulatory compliance, and GIS-enabled spatial data management, supported by an integrated digital platform using enterprise GIS, cloud-based field data tools, dashboards, and automated reporting. The project adds to Onterris’s North American energy infrastructure portfolio and aligns with its lifecycle environmental services strategy.
Onterris (NYSE: ONT) reported securing more than $9 million in new project awards in the first half of 2026 from one of the world’s largest integrated energy companies. These awards build on a multi-million-dollar, five-year global assessment, remediation, and reclamation contract awarded in 2025.
