Montrose Environmental Group, Inc. (NYSE: MEG) announced on April 21, 2026 that it will change its legal name to Onterris, Inc. and will begin trading under the new ticker symbol ONT on May 4, 2026. The name change became effective on April 17, 2026, and the ticker change will take effect on the New York Stock Exchange starting May 4.
The rebranding is part of a broader strategy to consolidate the company’s acquired brands—Montrose Environmental, ECT2, CTEH, Enthalpy Analytical, and Epic Environmental—into a single, science‑driven identity. By unifying its three integrated segments—Assessment, Permitting & Response; Measurement & Analysis; and Remediation & Reuse—Onterris aims to deliver a consistent client experience, strengthen market alignment, and support long‑term organic growth. The timing of the announcement, coinciding with Earth Day, underscores the company’s commitment to environmental stewardship.
Financially, the company reported a Q4 2025 earnings per share of $0.35 versus analyst expectations of $0.24, a beat of $0.11. Total revenue for the quarter was $193.27 million, up 19.3% year‑over‑year to $830.5 million in 2025, but the company experienced margin compression: operating margin fell to –1.3% and net profit margin to –4.3%. The Assessment, Permitting & Response segment contributed 44% of total revenues and grew 94% year‑over‑year, while the Measurement & Analysis and Remediation & Reuse segments saw lower operating margins. Despite the margin pressure, Onterris generated $87 million in free cash flow in 2025.
"Onterris is more than a new name. This brand reflects our company's evolution and role in solving some of the defining environmental challenges of our time. Our clients operate at the intersection of environmental responsibility, evolving regulatory frameworks and operational performance. By uniting our expertise across science, engineering, data and consulting, Onterris facilitates economic progress without compromising environmental stewardship, an approach that is especially meaningful as we celebrate Earth Day," said President and CEO Vijay Manthripragada.
"We believe this change will strengthen alignment, enhance client engagement and support continued long‑term organic growth," Manthripragada added.
The rebranding positions Onterris as a global pure‑play environmental solutions provider that leverages science, technology, data and field execution to help clients build resilience and reduce environmental and regulatory risk. The company’s patent‑pending VeriPlume Capture System™ for methane emissions measurement further differentiates its service offering. While margin compression remains a short‑term headwind, the company’s strong revenue growth, robust free cash flow and unified brand strategy are expected to drive long‑term value creation.
