Thomson Reuters (TRI) stock plummeted 5.04% in pre-market trading on Wednesday following the release of its second-quarter earnings report. Despite beating earnings estimates, the company's revenue fell short of analyst expectations, causing investor concern.

The information and media giant reported adjusted earnings of $0.87 per share, surpassing the analyst consensus of $0.82. However, quarterly sales of $1.785 billion missed the estimated $1.792 billion by a narrow margin. While this represents a 2.59% increase from the same period last year, the revenue miss appears to have overshadowed the earnings beat.

A key factor contributing to the stock's decline was the performance of Thomson Reuters' Legal Professionals segment, which saw revenues decrease by 3% at constant currency. This decline in the company's largest segment likely raised concerns among investors about future growth prospects. However, it's worth noting that the company maintained its full-year 2025 outlook for organic revenue growth, adjusted EBITDA margin, and free cash flow, suggesting confidence in its overall business trajectory.

Despite the market's negative reaction, Thomson Reuters highlighted some positive developments, including the launch of new AI solutions for its legal, tax, and accounting markets. CEO Steve Hasker emphasized the company's focus on product innovation and leveraging AI technology. However, these initiatives did not appear to offset immediate investor concerns about the revenue miss and segment performance.
