Montrose Environmental Group Is Now Onterris
Earth Day launch of new, unified brand highlights commitment “For Planet & Progress”
Little Rock, AR, April 21, 2026 — Montrose Environmental Group (NYSE: MEG, changing to ONT May 4, 2026) will mark Earth Day by rebranding to Onterris. The new, unified brand reflects a purpose and broader role in tackling complex environmental challenges with scientific rigor, operational quality and precise execution. It also aligns expertise and market awareness to position the Company for its next phase of growth. Founded 14 years ago and operating across the U.S., Canada and Australia, the Company is a leading pure-play environmental solutions provider. While the name is new, the mission remains unchanged: advancing our way of life without compromising the integrity of our environment.
At the heart of the new brand is a guiding principle: For Planet & Progress.
“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,” said Vijay Manthripragada, President and CEO of Onterris. “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.”
A brand inspired by the Earth and the responsibility we share
The Onterris brand draws inspiration from the “pale blue dot,” the image of Earth captured by NASA’s Voyager 1 from more than four billion miles away. That perspective reinforces the shared responsibility for our home. Combining “on,” symbolizing motion and intent, with “terris,” meaning earth, the name reflects a belief in practical, innovative, science-driven solutions to the real-world challenges that communities and industries face every day.
One name, many solutions
Onterris unites the Company’s distinctive environmental consulting, testing and treatment expertise under one global identity. The transition brings together brands, including Montrose Environmental in the U.S. and Canada, as well as ECT2, CTEH and Enthalpy Analytical in the U.S., and Epic Environmental in Australia, creating a clearer, more consistent experience for clients and partners across regions and services. We believe this change will strengthen alignment, enhance client engagement and support continued long-term organic growth.
Built for a changing operating environment
Environmental challenges are increasingly interconnected. Resource constraints, public health impacts, climate pressures and a rapidly changing regulatory environment continue to reshape industries and redefine how organizations manage risk and support growth. Onterris uses science, technology, data and field execution through a unified, evolving platform, helping clients build resilience and reduce environmental and regulatory risk to protect air, water and soil. We believe bringing these capabilities together under the unified Onterris brand will enhance client service and scale solutions to meet growing demand. This approach reflects a core belief that environmental responsibility and human progress are fundamentally intertwined.
Exhibit 99.1
In connection with its name change, the Company will change the common stock ticker symbol as listed on the New York Stock Exchange from ‘MEG’ to ‘ONT’. Both the name and ticker symbol changes will become effective on the New York Stock Exchange at the start of trading on May 4, 2026.
