What Is This Lawsuit About? The lawsuit alleges 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.

On January 20, 2026, Richtech filed its From 10-K, seven days past its extended deadline on January 13, 2026.

On January 27, 2026, Richtech announced a “hands-on collaboration” with Microsoft through Microsoft's AI Co-Innovation Labs to “jointly develop and deploy” agentic AI in robotic systems. On this news, the price of Richtech shares increased by $1.70 per share, or approximately 44.6%, from $3.81 per share on January 26, 2026 to close at $5.51 on January 27, 2026.

On January 28, 2026, Richtech announced a private placement of $38.7 million Class B shares. On this news, the price of Richtech shares declined by $0.43 per share, or approximately 7.8%, from $5.51 per share on January 27, 2026 to close at $5.08 on January 28, 2026.

On January 29, 2026, Hunterbrook Media issued a 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. On this news, the price of Richtech shares declined by $1.06 per share, or approximately 20.9%, from $5.08 per share on January 28, 2026 to close at $4.02 on January 29, 2026.

The Lead Plaintiff Appointment Process. The federal securities laws permit any investor who acquired eligible securities during the class period to seek appointment as lead plaintiff in a class action lawsuit. Courts typically appoint the investor(s) with the largest financial loss in the case and the ability to represent the class rather than investors with simply the largest investment portfolio. Courts regularly appoint individual investors, whether acting alone or as a group, as lead plaintiffs. The rights of any investor who bought shares during the class period are generally already protected. However, lead plaintiffs have the power to influence case strategy and have a say in settlement decisions, as well as decisions concerning allocation of settlement funds among class members.
