Thomson Reuters stock ripped higher after the company’s AI narrative finally came with a clean, measurable proof point and a capital-return catalyst. Shares jumped roughly 10% in the latest session as investors reacted to news that its AI assistant CoCounsel has reached one million professional users across legal, tax, risk and audit workflows—an adoption milestone that helps turn “AI potential” into “AI penetration.” Layer on a newly expanded buyback plan totaling US$600 million and a separate US$605 million return-of-capital move, and the day’s repricing starts to look less like a one-off pop and more like a story the market is trying to revalue in real time.
CoCounsel crosses one million users
For a company built on trusted content and workflow software, usage scale matters. Thomson Reuters said CoCounsel has now surpassed 1,000,000 professional users, spanning legal research and drafting, tax workflows, audit support, and risk and compliance tasks. The figure is important because it suggests AI is not stuck in pilot mode. It is increasingly embedded into day-to-day professional routines where switching costs are high and reliability expectations are unforgiving.
Leadership has framed CoCounsel around trust and accuracy rather than novelty—an approach tailored to regulated environments where “almost right” can be expensive. The platform is positioned as being grounded in licensed, authoritative content, supported by domain validation and designed with customer data ownership in mind. The company also pointed to deep specialist involvement, with 4,500+ subject-matter experts contributing to ongoing refinement and tax validation logic across its professional domains.
Anthropic recognition and a new CoCounsel Legal cycle
Beyond raw user counts, Thomson Reuters highlighted positive external attention for its AI direction, including recognition at a recent Anthropic briefing. That matters because the market has become more selective: investor appetite is strongest where AI claims come with credible technical partners, workflow integration, and clear pathways to monetization.
Thomson Reuters also signaled an upcoming launch of a new generation of CoCounsel Legal, described as an evolution that extends the AI rollout across its professional customer base and enables more conversational, task-oriented execution. If this release converts usage into broader seat expansion and pricing power, it could help re-anchor expectations around recurring revenue durability—one of the key reasons the stock tends to trade at a premium during confident cycles.
A repricing story, not just a rally
The market reaction arrives after a choppy stretch that has put valuation under the microscope. On the TSX listing, shares were referenced around CA$123.45 alongside a volatile recent return profile—an 8.8% gain over the past week, a roughly 27% decline over the past month, and a steep 50.9% decline over the past year. That combination points to a stock that has been heavily reassessed, with sentiment swinging between “steady compounder” and “multiple compression candidate.”
Analyst framing adds to the tension. A consensus target around CA$187.74 implies the stock is still roughly 34% below where the Street collectively sits. Some valuation models have described the shares as trading nearly 49.6% below estimated fair value, while near-term momentum has been clearly negative in the last month. The result is a classic setup: a business with durable franchises trying to prove a new growth lever at scale, while the market debates whether the current multiple fairly reflects execution risk.
$600M buyback and $605M return of capital
Capital allocation added a second leg to the move. Thomson Reuters announced plans to repurchase up to US$600 million of common shares under an amended normal course issuer bid approved by the TSX, with the updated program becoming effective February 27, 2026. Under the amended framework, the company may repurchase up to 16 million common shares, representing about 3.55% of its issued and outstanding shares (based on the stated reference share count in the program details).
Separately, the company outlined a US$605 million return-of-capital transaction expected to be completed in May, including an estimated special cash distribution of about US$1.36 per participating share, followed by a share consolidation designed to keep the economics proportional to the distribution. The package is intended to return proceeds associated with the prior sale of London Stock Exchange Group shares, while the buyback provides ongoing flexibility to manage share count and support per-share metrics.
For investors, the combined message is straightforward: Thomson Reuters is pursuing AI-led workflow expansion while also leaning into shareholder returns—an approach that can support valuation during periods when the market demands both growth credibility and disciplined capital use.

Key markers into the next earnings window
With the next earnings date referenced as April 30, 2026, the market will be looking for proof that AI adoption is translating into durable commercial outcomes rather than headline milestones alone. Focus is likely to remain on the pace of CoCounsel expansion into existing accounts, the pricing architecture across professional segments, and whether margins stabilize after the recent step-down that has been cited as a risk factor.
For now, the stock’s sharp move captures a moment when two forces aligned: a tangible AI adoption milestone and a capital-return blueprint that investors can model. If CoCounsel’s next product cycle extends usage into higher-value workflows and reinforces renewal strength, the valuation story can shift quickly. If not, the market’s recent tendency to punish uncertainty may reassert itself. The next few updates will decide whether this rally becomes a reset—or simply a bounce inside a longer repricing.
