The Globe and Mail reports in its Wednesday edition that Thomson Reuters posted higher third-quarter revenue Tuesday, boosted by investments in artificial-intelligence products in its legal and tax and accounting divisions. A Reuters dispatch to The Globe says the content and technology company also reaffirmed its full-year 2025 guidance of a 7-per-cent to 7.5-per-cent rise in organic revenue, which tracks income from existing businesses on a constant currency basis. Thomson Reuters shares fell as much as 5 per cent on the Canadian and New York stock exchanges. They had fallen 5.4 per cent this year up to Monday's market close, underperforming a 16.5-per-cent rise in the S&P 500, which has been lifted by big tech stocks. The owner of Westlaw legal database, Reuters news agency and the Checkpoint tax and accounting service reported Q3 adjusted earnings per share of 85 U.S. cents. Revenue rose 3 per cent to $1.78-billion (U.S.), meeting expectations for the third quarter, during which it launched new AI features in products in its legal and tax and accounting businesses. CEO Steve Hasker told Reuters that investments in AI in the legal division directly contributed to its 9-per-cent rise in organic revenue.
