Berger Montague Initiates Class Action Against Upstart Holdings, Inc. for Investors

Investor Alert: Class Action Lawsuit Against Upstart Holdings

In recent news, the prominent plaintiffs' law firm Berger Montague has unveiled a class action lawsuit targeting Upstart Holdings, Inc. (NASDAQ: UPST). This legal action arises on behalf of investors who acquired shares during the period from May 14, 2025, to November 4, 2025. Individuals affected by this situation have until June 8, 2026, to take significant action and potentially become lead plaintiffs in the case.

Overview of the Case

Upstart, a financial services company based in San Mateo, California, utilizes an advanced AI-driven lending platform that automates loan approvals through its proprietary model known as Model 22. However, recent allegations indicate that this model may not be as reliable as previously claimed.

According to the filed complaint, serious concerns were raised regarding the statements made by Upstart's management about the operational efficacy of Model 22. Specifically, the lawsuit claims that the defendants provided fundamentally misleading statements regarding the model's performance, suggesting an accuracy in loan approvals that was far from reality. This purportedly led to overstated revenues and ultimately hurt shareholder value when the granularity of these claims was revealed.

The Timeline of Events

On November 4, 2025, Upstart disclosed its earnings for the third quarter, which notably fell short of both the firm’s guidance and market expectations. The company reported a revenue of $277 million, compared to an anticipated $280 million, marking a significant miss of about $2.62 million. Following this alarming announcement, which also included a downward revision of its revenue expectations for the fourth quarter and the entire fiscal year, Upstart witnessed a dramatic decline in its stock price, plummeting by $4.49, or 9.71%, to a closing price of $41.75 on November 5, 2025.

During the earnings call, executives attributed these less-than-ideal results to the overreactive nature of Model 22, which supposedly miscalibrated credit assessments amid unfavorable macroeconomic signals. This admission came as a stark contradiction to prior declarations about the model’s stability and reliability in evaluating loan applications. The disclosures triggered immediate fallout within the investor community and led to an erosion of trust and confidence in Upstart’s business model.

Legal Implications and Next Steps

As the class action progresses, affected investors are encouraged to come forward and explore their options for participation in the lawsuit. Berger Montague has placed a strong emphasis on investor rights, urging anyone who purchased Upstart shares during the specified period to engage with the firm for a detailed understanding of their legal standing.

This situation highlights the critical need for transparency in corporate communications, especially when dealing with advanced technology such as artificial intelligence in financial services. Investors must remain vigilant and informed about the complications that can arise in the rapidly evolving landscape of fintech.
