Richtech Robotics Inc., the developer behind the AI-powered bartender, barista, and beverage robot ADAM, is now facing a proposed class action lawsuit claiming the company misled investors about its collaboration with Microsoft. The suit asserts that the company exaggerated the scope of its involvement with the tech giant, artificially boosting its stock price before closing a major private placement deal.
The complaint, filed Monday in the U.S. District Court for the District of Nevada, alleges that Richtech overstated its relationship with Microsoft’s AI Co-Innovation Labs. The labs reportedly offered only a brief, week-long development sprint, contrary to Richtech’s claims of a joint engineering project. Investors were left with the impression of a broader, commercial collaboration that did not exist.
Investor Claims and Timeline
Investor Luis Gonzalez Diez, who filed the complaint, seeks to represent a class of shareholders impacted during the proposed period beginning January 27, 2026. On that morning, Richtech issued a press release announcing a partnership with Microsoft to enhance the ADAM robot, a device capable of making cocktails, coffee, and bubble tea.
Following the announcement, Richtech shares surged nearly 45%, closing at $5.51 on January 27. The next day, the company disclosed a $38.7 million private placement agreement, issuing 8.5 million new shares to an institutional investor. Richtech expected to close the deal on January 29, and the company later confirmed the transaction was completed as planned.
The lawsuit claims these events misled investors about the company’s financial stability and growth prospects. Gonzalez Diez asserts that the press release suggested a significant collaborative and commercial relationship with Microsoft that did not exist. According to the complaint, Microsoft described its program as a “standard customer offering with no commercial element.”
Once media coverage clarified the nature of the Microsoft collaboration, Richtech shares fell sharply from over $5 to below $3.60 within two trading days, representing a substantial market impact.
