Montrose Environmental Group NYSE: MEG reported what management described as a record year in 2025, citing new highs in revenue, adjusted EBITDA, and cash flow while introducing 2026 guidance that calls for continued growth and further margin improvement. Executives also pushed back on investor concerns that U.S. regulatory volatility could meaningfully weaken demand, pointing instead to private-sector driven activity and expanding opportunities in water treatment, emissions monitoring, and industrial end markets.
Record 2025 results and margin expansion
President and CEO Vijay Manthripragada said 2025 was “the strongest year” in the company’s history, with revenue of $830.5 million and consolidated adjusted EBITDA of $116.2 million. Revenue rose 19.3% versus 2024, including 12.7% organic growth, which management said exceeded its long-term target of 7% to 9%.
Consolidated adjusted EBITDA increased 21.3% year over year, and adjusted EBITDA margin expanded for the third consecutive year to 14% in 2025, representing 180 basis points of improvement since 2022, according to management.
Chief Financial Officer Allan Dicks added that fourth-quarter revenue rose to $193.3 million from $189.1 million a year earlier. Fourth-quarter consolidated adjusted EBITDA was $23.9 million, or 12.4% of revenue, compared with $27.2 million, or 14.4%, in the prior-year quarter. He attributed the quarterly margin decline to lower margins in Measurement and Analysis and Remediation and Reuse, plus expenses tied to winding down the renewables business, partially offset by improved consulting and advisory margins.
Cash flow strength and balance sheet actions
Management emphasized cash generation as a key 2025 highlight. The company reported $107 million in operating cash flow, which it said represented a 93% conversion of consolidated adjusted EBITDA, well above its long-term target of 50% or more. Montrose also generated $87 million of free cash flow, or 75% of adjusted EBITDA.
Dicks said the company fully redeemed the remaining $122 million of its Series A-2 preferred stock on July 1, 2025, six months ahead of schedule, eliminating future preferred dividends and simplifying its capital structure. Montrose ended 2025 with a 2.5x leverage ratio—below its target of under 3x—and $225 million of available liquidity.
Segment performance: consulting surge, lab and air quality margins, renewables wind-down impact
Dicks outlined full-year performance across Montrose’s three operating segments:
- Assessment, Permitting and Response (APR): Revenue increased 43% to $307.4 million, driven by organic growth in non-response consulting and advisory services, emergency response growth, and contributions from 2024 acquisitions. Segment adjusted EBITDA rose to $68.5 million from $48.0 million, with a margin of 22.3%, essentially flat year over year. Management said it expects margins to strengthen in 2026 due to demand, pricing discipline, and operational efficiency.
- Measurement and Analysis: Revenue grew 9.6% to $245.9 million, reflecting increased demand for air quality and laboratory services and 2024 acquisition contributions. Segment adjusted EBITDA improved to $64.4 million, or 26.2% of revenue, versus 22.5% in 2024, a 370 basis point margin expansion. Dicks said the company expects margins to remain elevated, though “modestly lower” than 2025.
- Remediation and Reuse: Revenue increased 7.8% to $277.3 million. Organic growth in water treatment and 2024 acquisition contributions were partially offset by $9.8 million of lower renewables revenue tied to a strategic wind down and exit. Segment adjusted EBITDA declined to $36.3 million from $38.3 million, with margin falling to 13.1%, primarily due to a $4.4 million loss associated with the renewables wind down. Management expects margins to improve in 2026 as water treatment grows and operating leverage increases.
Regulatory backdrop: methane, PFAS, and private-sector demand
Manthripragada addressed what he called a “persistent narrative” that U.S. regulatory volatility is a meaningful headwind, arguing the 2025 results demonstrate demand remains constructive. He said approximately 90% of Montrose’s clients operate in private-sector industries such as energy, utilities, transportation, manufacturing, chemicals, and technology, and that U.S. federal government exposure is less than 3% of revenue.
On methane, he said recent U.S. EPA framework changes are not expected to have a material near-term impact on Montrose’s services. He noted the company’s methane work is concentrated with large operators in states with stringent independent regulations, and pointed to the EU Methane Regulation as extending emissions monitoring and abatement requirements to exporters, including U.S. LNG and oil producers.
On PFAS, management said it is already a “high-margin growth driver.” Manthripragada cited EPA clarity on national PFAS standards in 2025 and ongoing state actions as demand drivers, including tightening expectations around landfill leachate. In the Q&A, he said PFAS-related revenue remains about 10% to 15% of the business, with double-digit growth expected into 2026.
He also stressed the company’s water treatment opportunity is broader than PFAS, characterizing Montrose as a “water technology business” and citing a water treatment total addressable market of more than $250 billion.
2026 guidance, cadence, and capital allocation priorities
Montrose introduced 2026 guidance of $840 million to $900 million in revenue and $125 million to $130 million in consolidated adjusted EBITDA. The guidance assumes no acquisitions. At the midpoint, management said it implies roughly 10% adjusted EBITDA growth versus 2025 and targets about 15% adjusted EBITDA margin.
Management said it expects revenue to be roughly split 50/50 between the first and second halves of 2026, while adjusted EBITDA is expected to be 40% in the first half and 60% in the second half, reflecting project timing. Within the first half, executives expect Q1 to be seasonally slower, with emergency response revenue a key variable. The company’s 2026 assumption for environmental emergency response revenue is $50 million to $70 million.
On cash conversion, Manthripragada said the company does not expect to repeat the 93% operating cash conversion level from 2025, but it is targeting 60% operating cash conversion in 2026, above its long-term 50%+ target. He added the company expects to generate approximately $180 million in cumulative operating cash flow across 2025 and 2026.
Montrose also outlined capital allocation plans following its balance sheet simplification. Manthripragada said the company plans to continue investing 1% to 2% of revenue annually in proprietary technology, software development, patents, R&D, and growth capital expenditures. He also said the company intends to begin returning capital to shareholders through its existing $40 million share repurchase authorization.
On M&A, management said it is positioned to return to acquisitions in 2026 after pausing in late 2024, with a focus on “highly strategic accretive tuck-ins.” In response to a JPMorgan question, Manthripragada said no deals appear imminent in Q1 or early Q2 and that potential bolt-on activity is more likely in the back half of 2026, with opportunities identified in testing and consulting across Australia, Canada, and the U.S.
