What is the Richtech Robotics Lawsuit About?

The lawsuit alleges that “Defendants made false and/or misleading statements and/or failed to disclose 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.”

Previously on January 27, 2026, Richtech Robotics had announced a “hands-on collaboration” with Microsoft through Microsoft's AI Co-Innovation Labs to “jointly develop and deploy” agentic AI in robotic systems. However, Hunterbrook Media claims that Microsoft denied having a partnership with the company, saying that Richtech Robotics is “just a customer,” and that it participated in the AI Co-Innovation Lab as “a standard customer engagement” that had “no commercial element.”

Additionally, Hunterbrook claims that just weeks earlier, Richtech Robotics missed its extended 10-K filing deadline. According to Hunterbrook, Richtech Robotics filed an NT 10-K (notification of late filing) in December 2025, which seemingly delayed its 10-K filing deadline to January 13, 2026. However, Richtech Robotics did not file the 10-K until seven days after the extended deadline, on January 20, 2026. As a result, Hunterbrook questions whether Richtech Robotics may have received a deficiency notice from NASDAQ but failed to publicly disclose it in accordance with NASDAQ’s requirements.

Following Hunterbrook’s report, shares of Richtech Robotics plummeted over 20% in intraday trading on January 29, 2026, causing significant harm to investors.
