Richtech Robotics Hit With Securities Suits Over Microsoft Claims as April 3 Lead‑Plaintiff Deadline Nears

Overview

• Multiple investor law firms, including Berger Montague, Hagens Berman, the Rosen Law Firm, Faruqi & Faruqi, the Law Offices of Howard G. Smith, and Kirby McInerney, have filed or announced class actions and are soliciting lead plaintiffs.
• The complaints focus on a Jan. 27 press release in which Richtech touted a "hands-on collaboration" and "joint engineering effort" with Microsoft through the AI Co‑Innovation Labs.
• On Jan. 29, Hunterbrook Media reported that Microsoft called the engagement a standard customer program with no commercial element, and Richtech’s stock fell about 21% that day and nearly 30% by Jan. 30.
• Plaintiffs are also scrutinizing Richtech’s Jan. 28 at‑the‑market private placement of approximately 8.5 million Class B shares, characterizing it as dilutive.
• The proposed class period runs from Jan. 27 to Jan. 29, 2026 (with some notices specifying through 12:00 p.m. ET on Jan. 29), and notices emphasize that no class has been certified.
