Shares of Richtech Robotics fell over 20% on January 29, 2026, following the release of a Hunterbrook report alleging that the company mischaracterized a non-commercial participation in Microsoft’s AI Co-Innovation Labs as a “close collaboration.” According to the report, Microsoft stated that the engagement was a standard customer program with no commercial element, despite Richtech’s public statements implying a meaningful partnership. The report further noted that the announcement preceded a dilutive private placement and followed Richtech’s failure to file its Form 10-K in a timely manner, raising questions about the accuracy of the company’s prior disclosures.
A lawsuit has been filed against Richtech, alleging that: (1) Richtech claimed that it had a collaborative and commercial relationship with Microsoft when it did not; and (2) as a result, defendants’ statements about Richtech’s business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at all times. When the true details entered the market, investors suffered damages.
