About Montrose Environmental Group, Inc.

Montrose Environmental Group, Inc. is a U.S.-based environmental services company listed on the NYSE under the ticker MEG, with corporate headquarters in North Little Rock, Arkansas, United States. For French-speaking investors in France, Belgium and Switzerland, it stands out as a specialized environmental platform operating at the intersection of regulatory compliance, scientific consulting, engineering, testing, and remediation. The company describes itself as a leading environmental services provider with operations across North America, Australia and Europe, serving both government and commercial customers. ([sec.gov](https://www.sec.gov/Archives/edgar/data/0001643615/000095017025043826/2025_ars_final.pdf)) The company was founded roughly 14 years ago and has expanded through a combination of organic growth and selective acquisitions, building a broader platform by integrating complementary environmental capabilities. Montrose reports its business through three operating segments: Assessment, Permitting and Response; Measurement and Analysis; and Remediation and Reuse. The first segment covers scientific advisory services, environmental assessments, emergency response, toxicology support and permitting-related work. The second provides air measurement, emissions monitoring, laboratory analysis and environmental testing. The third focuses on remediation, reuse and certain treatment-related activities, including water treatment and contamination-related solutions. ([sec.gov](https://www.sec.gov/Archives/edgar/data/0001643615/000095017025043826/2025_ars_final.pdf)) From a competitive standpoint, Montrose benefits from a differentiated integrated model. Management has indicated that few competitors offer the same breadth of environmental solutions across science, field services, analysis and remediation. That breadth supports cross-selling, deeper client relationships and more resilient demand over time. The business also sits within a structurally supported industry, where regulation, industrial compliance, environmental risk management and cleanup obligations create recurring demand for specialized expertise. ([sec.gov](https://www.sec.gov/Archives/edgar/data/0001643615/000095017025043826/2025_ars_final.pdf)) Its core offerings include air quality measurement, laboratory services, environmental consulting, permitting support, emergency response services, engineering, remediation and water-treatment-related solutions. Geographically, Montrose has a diversified footprint across North America, Australia and Europe, which broadens its exposure to different regulatory regimes and industrial end markets.

In 2025, Montrose reported record results, citing strong organic growth, margin expansion and robust cash generation. The company also launched an inaugural share repurchase program and redeemed part of its preferred equity, while reiterating an acquisition pause to prioritize organic execution, balance-sheet improvement and capital discipline. More recently, in April 2026, Montrose announced a rebrand to Onterris, with a planned ticker change to ONT on May 4, 2026, underscoring a new strategic phase while maintaining the same environmental mission.
