Law firm investigates Upstart Holdings for possible securities fraud after Q3 miss.

Pomerantz LLP is investigating claims against Upstart Holdings and some of its officers for potential securities fraud following the company's announcement on November 5, 2025, that it missed third-quarter expectations due to reduced borrower approvals and conversion rates from its Model 22 underwriting system. This news caused Upstart's stock price to drop sharply, harming investors. The investigation could lead to a class action lawsuit as the firm seeks to protect investors' rights and recover damages.
