Business-Segment Outlook:

• Measurement and Analysis: Focus remains on resource utilization and disciplined execution; segment revenue growth expected to be moderate compared to water treatment.
• Emissions Management: Anticipated expansion of market opportunity for optical gas imaging and software/data capabilities following U.S. EPA's proposed reconsideration of Clean Air Act methane regulations.

Market and Competitive Outlook:

• Regulatory Trends: Expect recent environmental regulatory volatility to subside, creating a net positive for client certainty and business trajectory.
• Demand Drivers: Increased client engagement regarding PFAS deadlines (pushed to ~2030) and interest in water stewardship from onshoring industries (semiconductor, pharma, waste).
• Competitive Positioning: Rebranding to "OnTerrace" and unified portfolio expected to drive higher cross-selling of bundled services; clients viewing the company as a larger, integrated provider, resulting in larger and longer-term awards.
• Industry Structure: No material structural changes anticipated; business remains resilient across election cycles due to private-sector client base and state/local regulatory requirements.

Macro / Industry Outlook:

• Economic/Political Environment: Recent shift in Washington D.C. balance of power expected to reduce federal regulatory volatility; business thesis unchanged despite political shifts.
• Geopolitical/Regulatory: Federal regulatory volatility expected to decrease, benefiting clients and the company's trajectory.

Strategic Initiatives:

• M&A: Completed three acquisitions totaling ~$14M investment (U.S. Mountain States ambient air monitoring, ECOS Environmental Consultants in Australia, Permian Basin Environmental Lab in Texas). These are expected to be de minimis for 2026 but accretive to the 2027–2030 timeframe.

• Capacity: Newly constructed Houston lab to be strengthened by Permian Basin acquisition.
• Share Repurchases: 1.6M shares repurchased in 2026 (~$30M); ~$10M remaining capacity under the $40M authorization. No specific future repurchase volumes disclosed beyond subject-to-governance.
• Strategic Review: Board-led strategic review ongoing with no timetable for conclusion; no assurance of a transaction outcome.

Risks and Headwinds to Outlook:

• Execution Risks: Revenue variability may occur due to the normalization of recovery services following a significant environmental event in 2025.
• Strategic Review: No assurance that the ongoing strategic review will result in a transaction or specific outcome.
• Regulatory Timeline: EPA methane regulations are currently proposed; final rule-making timeline and specific impact magnitude depend on the completion of the regulatory process.
• Acquisition Timing: Recent acquisitions occurred post-quarter-end, limiting 2026 impact but introducing integration variables for future periods.
