Thomson Reuters Stock Falls 7%: Revenue Rose, AI Costs Bit

Thomson Reuters stock fell about 7% on Tuesday, November 3, 2026, even as the company reported higher revenue and raised its full-year outlook — because investors focused on what its artificial intelligence push is costing. Shares traded at $113.46 on Nasdaq in the Reuters report, down from a prior close of $122.24, after third-quarter earnings of 81 cents a share came in just below expectations.

What happened

Thomson Reuters, the Toronto-based owner of the Westlaw legal database, the Reuters news agency and the Checkpoint tax and accounting service, reported a 10% rise in third-quarter revenue to $1.83 billion. Adjusted earnings per share were $0.81, missing consensus estimates of $0.82 to $0.83 by a cent and down from $0.85 a year earlier. Revenue was also just below the roughly $1.84 billion analysts had expected in some surveys.

At the same time, the company raised its outlook. It now expects full-year 2026 organic revenue growth of 8.5% to 9.0%, up from about 8% before, and total revenue growth of about 9.5%. In other words, the top line got stronger — but the share price went the other way.

Why it is blowing up

The sell-off is about margins, not demand. In the legal division, margins fell to 46.6% from 49%, pressured by higher AI spending, $22 million in severance costs and the impact of buying Noetica, an AI data and analytics platform. That combination landed on a day when investors were already punishing companies for the cost of the AI buildout, a theme that also weighed on Apple and Palantir in the same session.

Thomson Reuters is the latest example of a difficult trade-off now facing information companies. AI is driving new sales — revenue rose by double digits across its combined legal, tax and accounting and corporates segments, helped by recurring revenue and new AI upgrades to CoCounsel Legal and CoCounsel Tax, Audit and Accounting. But building and buying those AI tools costs money up front, and the market on Tuesday chose to price the cost before the payoff.

Key facts

• Revenue: $1.83 billion in Q3, up 10% year over year.
• Earnings: Adjusted EPS of $0.81, versus $0.85 a year ago and consensus around $0.82-$0.83.
• Share move: Down about 7% at $113.46 in Reuters reporting; other intraday reports put the fall at 8.3%, after a prior close of $122.24. The stock is down more than 14% so far in 2026.
• Guidance raised: Full-year organic revenue growth now seen at 8.5%-9.0%, up from about 8%.
• Margin pressure: Legal division margin 46.6%, down from 49%, with AI spending, $22 million of severance and the Noetica deal all weighing.
• Reuters news strength: Revenue at Reuters rose 12%, boosted by generative AI licensing, with transaction revenue in the news division up 56% to $44 million.
• Print exit: The company excluded its global print division after selling a majority stake; Baystreet reported the 51% stake sale to KKR for $500 million was completed.

Executives said they expect higher revenue from premium-tier pricing for AI agentic products to offset the AI spending in the legal division over time. That promise is central to the story: if premium pricing lands, Tuesday's margin squeeze looks temporary; if it does not, the costs keep recurring.

What is next

Watch two things. First, whether the legal margin recovers as CoCounsel premium tiers roll out — management's own test for whether the spending is working. Second, whether AI licensing continues to lift the Reuters news business at the pace seen this quarter, after transaction revenue jumped 56%. Thomson Reuters reports in a market that is currently rewarding AI revenue and punishing AI costs, sometimes in the same earnings release. Tuesday showed it can do both at once.
