Law firm Robbins Geller has initiated a class action lawsuit against Richtech Robotics Inc., alleging the company made material misrepresentations regarding a business relationship with technology giant Microsoft. The complaint centers on Richtech's characterization of the partnership, which Microsoft clarified on January 29, 2026, was limited to a standard AI Co-Innovation Lab rather than a commercial collaboration as the company had implied.
The disclosure triggered a significant market reaction, with Richtech's stock declining more than 29% over a two-day trading period following Microsoft's public statement. The sharp correction suggests investors may have relied on representations about the nature and scope of the Microsoft engagement when making investment decisions. The lawsuit seeks to recover losses for shareholders who held positions during the period when the company's characterization of the partnership remained in dispute.
Investors interested in participating in the litigation have until April 3, 2026, to petition for appointment as lead plaintiff. The deadline marks an important date for shareholders seeking to take an active role in the case. Legal representatives are accepting inquiries from those who experienced substantial losses in Richtech securities during the relevant period.
