Revenue by Segment
Breaks revenue down by service line (for example remediation, monitoring, or consulting), showing which parts of the business drive growth and which rely on cyclical end-markets. Helps investors see whether Montrose’s revenue mix is diversifying or concentrated in higher-risk areas.
Measurement & Analysis is the steady, margin-accretive engine delivering consistent growth, while Assessment, Permitting & Response drove the 2025 jump but is clearly lumpy—reflecting emergency response timing that management flags as volatile. Remediation & Reuse has moved higher in revenue but suffered margin pressure from a strategic renewables wind‑down; its recovery will be key to sustaining consolidated margins. In short, organic momentum looks genuine, but near‑term earnings cadence and margins will hinge on emergency‑response timing and remediation margin normalization.
