Thomson Reuters: How CoCounsel Could Reshape Legal Workflows—Is Thomson Reuters Building the AI Assistant Leader?

Thomson Reuters reported its third-quarter 2025 earnings, showcasing both momentum in key areas and some challenges impacting overall growth projections. The company experienced strong organic revenue growth of 7%, with the “Big 3” segments—Legal Professionals, Corporates, and Tax & Accounting—driving 9% growth. Significantly, the Legal Professionals segment saw an acceleration to 9% organic growth, bolstered by the continued success of Westlaw and CoCounsel products. However, organic revenue growth for the full year is now expected to be closer to 3% and 7% due to external factors such as a slower ramp-up of commercial print volumes, U.S. federal government cancellations, and softer bookings in the Corporate segment. In terms of profitability, Thomson Reuters reported an adjusted EBITDA increase of 10% to $672 million, with margins improving 240 basis points to 37.7%, higher than anticipated due to beneficial revenue mix and cost management.
