The shares were up $13.09 or almost 12 per cent at $123.93 in early afternoon trading on the Toronto Stock Exchange.
CoCounsel is the technology underlying the generative and agentic capabilities in the company's legal, tax, accounting, audit, risk, compliance and corporate solutions.
Thomson Reuters says the users are spread across 107 countries and territories.
