Definitive Healthcare reported Q2 fiscal 2026 revenue of $55.2 million, down 9% year-over-year, while adjusted EBITDA of $14.6 million exceeded guidance. The company generated $11.6 million in unlevered free cash flow during the quarter. CEO Kevin Coop said the firm's diversified and provider businesses, representing over 60% of revenue, are recovering faster than its life sciences segment. Trailing-12-month net dollar retention improved for the second consecutive quarter. The biopharma segment posted its strongest new-business quarter in three years outside Q4, including four returning customers. CFO Casey Heller noted that claims-data-related downselling has begun to lessen after adding new data sources, though it remains early to assess full impact.

Definitive Healthcare has launched an early adopter programme for its new AI-powered healthcare intelligence platform. The Nasdaq-listed company combines its healthcare data assets with conversational AI to surface insights across providers, organisations, claims, affiliations, and consumer datasets. The platform enables users to size market opportunities, optimise sales territories, identify high-value prospects, surface decision makers, and reduce patient leakage. Select customers from health systems, life sciences organisations, and other healthcare-focused industries are being invited to participate from August 2026. Feedback from early adopters will shape the final product before general availability launches in late 2026. The platform allows organisations to ask complex questions and make faster strategic, commercial, and product development decisions across the healthcare ecosystem.
