Guidewire Software's stock plummeted 13.37% in post-market trading following the release of its third-quarter fiscal 2026 financial results.

The property and casualty insurance software provider reported adjusted earnings per share of $0.82, surpassing the consensus estimate of $0.74, while revenue of $372.5 million also beat expectations of $355.95 million. Despite the double beat, the stock reversed sharply lower. Analysts noted that shares had rallied over 6% during the regular trading session in anticipation of strong results, suggesting the positive earnings may have already been fully priced in by the market.

The company also provided its outlook, forecasting fourth-quarter revenue between $396 million and $406 million, compared to a FactSet estimate of $394.1 million, and raising its full-year revenue guidance to a range of $1.46 billion to $1.47 billion.
