Shares of Intuit (INTU), the maker of TurboTax and QuickBooks, plummeted 5.41% in after-hours trading on Thursday following the release of its fourth-quarter earnings report and disappointing first-quarter revenue growth forecast. Despite beating expectations for the fourth quarter, investors focused on the company's cautious outlook for the upcoming quarter.

Intuit reported strong fourth-quarter results, with adjusted earnings per share of $2.75, surpassing analysts' estimates of $2.66. Revenue for the quarter came in at $3.83 billion, also beating the expected $3.75 billion. However, the company's forecast for first-quarter revenue growth of 14% to 15% fell short of Wall Street's expectations of 16.1% growth, triggering the sell-off.

The weaker-than-expected guidance for Q1 appears to be primarily driven by challenges in Intuit's Mailchimp marketing platform, which is part of its Global Business Services segment. CFO Sandeep Aujla acknowledged these issues, stating, "The one area that we call out, which is a near term temperament to growth, is Mailchimp, but we have plans to make sure that scores correctly, and that's exiting the year at good pace."

Despite the near-term headwinds, Intuit provided a full-year fiscal 2026 outlook that was largely in line with analyst expectations, projecting revenue between $21 billion and $21.19 billion. The company continues to focus on integrating artificial intelligence across its product suite and recently launched AI agents for its QuickBooks portfolio. Additionally, Intuit announced a new $3.2 billion share buyback authorization, suggesting management's confidence in the company's long-term growth prospects.
