Thomson Reuters Falls on Q3 Revenue and Profit Miss

The disappointment mattered because Thomson Reuters is not being valued like a slow-growing defensive publisher. Its portfolio of legal, corporate, tax, audit and accounting customers now accounts for 88% of revenue, and those “big three” segments still grew 10% in the quarter. That is a healthy performance, but not one that justifies a lofty multiple if investors believe the growth path is already well understood.

Management did offer a modestly better longer-term picture, lifting its forecast for 2026 revenue growth to 9.5% from 8% after the Oct. 1 sale of its global print business. But that guidance boost was not enough to offset the near-term earnings miss, particularly given the stock’s rich valuation. By one common measure, Thomson Reuters is trading at a PEG ratio of almost 4.7, far above the level many investors view as fair value.

The reaction also reflects a broader market pattern in which high-quality software and data names are being rewarded only when they beat by a wide margin. Thomson Reuters is still executing well, and the print divestiture should sharpen its focus on higher-margin digital businesses. But with the shares already sitting on elevated expectations, investors appear to want proof of accelerating growth, not just confirmation that the core franchise remains resilient.

For shareholders, the key question now is whether the company can turn its legal and professional-information businesses into sustained earnings upside fast enough to justify the premium. If growth in the core segments keeps compounding and the mix shift away from print continues, the stock can recover. If not, the pullback suggests the market is prepared to punish even decent results when the valuation leaves little room for error.
