• Long-term outlook (through 2030) projects revenue CAGR of ~15% and adjusted EBITDA CAGR of ~25%, assuming ~10% organic revenue growth (up from the previous 7-9% range).
• Year-end leverage is expected to settle around 2.5x, inclusive of recent acquisition investments.
• Management anticipates elevated growth in the water treatment sector and continued margin expansion due to favorable project mix and operational efficiencies.
• A rebranding from Montrose Environmental Group to OnTerrace (completed in early 2026) is driving integrated commercial offerings and cross-selling opportunities.

Business Segments and Product Lines:

• Consulting and Treatment Segment: Revenue was $142 million (down from $161.9M); adjusted EBITDA margin expanded to 21.7% (from 18.4%) driven by core consulting strength and water treatment growth, excluding the prior year recovery event.
• Measurement and Analysis Segment: Revenue declined to $61.1 million (from $63 million), primarily due to lower field services; adjusted EBITDA margin was 26.1% (down from 27.5%) due to a lower revenue base and project mix.
• New Products/Regulations: Emerging opportunities identified in emissions management driven by EPA proposals to reconsider Clean Air Act methane regulations, leveraging optical gas imaging and software capabilities.
• Acquisitions: Completed three strategic acquisitions totaling ~$14 million, including assets in U.S. mountain states (air monitoring), ECOS Environmental Consultants (Australia), and Permian Basin Environmental Lab (Texas), enhancing geographic reach and technical capabilities.

Market and Competitive Landscape:

• Ranked the 5th largest global environmental pure-play company by ENR; business remains resilient across political election cycles due to a predominantly private-sector client base and reliance on state/local regulations.
• Market trends indicate a shift toward regulatory certainty post-election, expected to be a net positive despite volatility.
• Water treatment market is expanding beyond PFAS to include broader industrial wastewater and municipal drinking water, particularly in onshoring sectors (pharma, semiconductor, waste).
• Rebranding to OnTerrace is improving market perception as an integrated provider, leading to more bundled service requests and longer-term client awards.

Risks and Challenges:

• Revenue volatility remains a risk due to the non-recurring nature of environmental emergency response events, which accounted for significant prior-year comparisons.
• Regulatory volatility at the federal level could fluctuate, though management believes state/local requirements provide a stabilizing underpinning.
• The strategic review announced in August 2026 is ongoing with no timetable for conclusion, introducing uncertainty regarding potential transactions.
• Year-to-date results include a net loss of $2.3 million due to lower fair value gains on financial instruments (following a $20M gain in the prior year) and higher interest expenses.

Management Commentary and Tone:

• Tone was confident and optimistic, emphasizing strong execution against Q2 expectations and record margin performance.
• Management highlighted "structural improvements" in operating leverage and cost discipline rather than one-time gains.
• Emphasis placed on the resiliency of the business model and the strategic value of the recent rebranding and acquisitions.
• Leadership reiterated commitment to disciplined capital allocation, targeting small, accretive bolt-on acquisitions to maintain leverage targets.

Analyst Questions and Answers:

• EBITDA Margins (William Blair): Management confirmed expectations for margins to reach high teens/low 20s by 2030, driven by mix and corporate expense leverage.
• Cash Flow & DSO (William Blair): Q3 cash flow strength attributed to seasonality, the completion of the annual incentive payment cycle in Q1, and natural receivables unwind in Q4.
• Organic Growth Drivers (JP Morgan): The 10% CAGR is a long-term trend rather than 2027 guidance; key drivers include expanded water treatment opportunities beyond PFAS and broader industrial client engagement.
• Cross-Selling Impact (Clear Street): While specific cross-sell percentages are not yet disclosed, management reported an integrated commercial approach leading to larger, multi-service awards and better client visibility into bundled offerings.
• Acquisition Impact (Capital One): The $14M in acquisitions is de minimis for 2026 but expected to be accretive to 2027-2030; the deal pipeline remains robust with a focus on disciplined, small bolt-ons.
• Political Landscape (Capital One): Recent election results are viewed as reducing regulatory volatility, offering a net positive, though the business is deemed resilient regardless of federal power shifts.

Other Key Points:

• The company realigned reportable segments in 2026, aggregating Permitting/Response and Remediation/Reuse into a single "Consulting and Treatment" segment.
• A $40 million share repurchase program was announced, with $30 million utilized (1.6M shares) and $10 million capacity remaining.
• The Series A2 preferred shares were fully redeemed in the prior year, contributing to adjusted EPS benefits in the current period.
• Management is in active discussions with clients regarding the EPA's proposed methane regulations, expecting these to drive recurring testing revenue.
