Montrose Environmental revenue falls to $168.5M in Q1 as severe weather disrupts field operations

Montrose Environmental Group, now operating as Onterris, reported first-quarter revenue of $168.5 million, down from $177.8 million in the prior year, as severe winter weather and reduced environmental emergency response activity impacted results. CEO Vijay Manthripragada attributed the decline to timing rather than weakening demand. Despite the revenue drop, profitability remained resilient with adjusted EBITDA at $17.8 million and margins nearly flat at 10.6%. The Consulting and Treatment segment saw improved margins, whilst Measurement and Analysis faced weather-related pressures. Management reaffirmed full-year 2026 guidance of $840 million to $900 million in revenue and $125 million to $130 million in adjusted EBITDA, expecting revenue to shift towards the second half. The company recently rebranded to Onterris following an 18-month integration effort.
