Thomson Reuters (TRI) shares plummeted 5.22% during intraday trading on Tuesday, despite the company reporting first-quarter earnings that surpassed analyst expectations.

The decline appears to be driven by persistent investor concerns about artificial intelligence disruption in the professional information services sector. According to a Barron's report, Thomson Reuters has been "one of the big victims of fears of artificial-intelligence disruption," with its stock remaining down more than 50% from highs above $200 in 2025 following a slide induced by AI concerns.

The company reported strong Q1 results with adjusted earnings of $1.23 per share on revenue of $2.09 billion, both representing 10% year-over-year growth and beating analyst estimates. However, investors remain focused on competitive threats from AI providers like Anthropic, which released a legal tool in February aimed at automating routine legal work. CEO Steve Hasker noted that Thomson Reuters is developing its own AI model for legal tasks and that 30% of the company's annualized contract value now comes from AI-enabled products.
