Philadelphia, Pennsylvania--(Newsfile Corp. - April 15, 2026) - National plaintiffs' law firm Berger Montague PC announces a class action lawsuit against Upstart Holdings, Inc. (NASDAQ: UPST) ("Upstart" or the "Company") on behalf of investors who purchased or acquired Upstart shares during the period from May 14, 2025 through November 4, 2025 (the "Class Period").

Investor Deadline: Investors who purchased or acquired Upstart securities during the Class Period may, no later than June 8, 2026, seek to be appointed as a lead plaintiff representative of the class. To learn your rights, CLICK HERE.

Upstart, headquartered in San Mateo, Calif., operates an AI-driven lending platform that automates loan approvals and credit risk assessment through its proprietary Model 22.

The Complaint alleges that defendants overstated the performance of Upstart's AI-driven lending platform, specifically Model 22, while failing to disclose that the model overreacted to macroeconomic signals, and that this overresponsive[ness] had a significant negative effect on revenue.

The true state of the Company's operations began to be revealed on November 4, 2025, when Upstart reported Q3 2025 revenue of $277 million, below guidance and consensus estimates. The Company also projected Q4 revenue of $288 million and revised FY 2025 revenue downward to $1.035 billion from prior guidance of $1.055 billion. During the earnings call, defendants admitted that Model 22's calibration had been "more conservative on the credit side" and that the model's overresponsive[ness] would continue to negatively impact revenue.

On this news, Upstart's stock declined $4.49 per share, or 9.71%, to close at $41.75 per share on November 5, 2025.
