Richtech Robotics Faces Securities Class Action Over Microsoft Tie as Firms Seek Lead Plaintiff

Overview

• Plaintiffs filed Diez v. Richtech Robotics Inc., No. 26-cv-00231 (D. Nev.), alleging violations of Sections 10(b) and 20(a) and SEC Rule 10b-5.
• The complaint centers on claims that Richtech portrayed a collaborative, commercial relationship with Microsoft that Microsoft described as a standard, noncommercial Co‑Innovation Lab engagement.
• Hunterbrook Media’s January 29 report quoting Microsoft preceded a sharp selloff, with shares down 20.87% that day and about 29% over two trading days, according to filings.
• Disclosures cited in notices include a January 27 press release touting a collaboration, a January 28 at‑the‑market private placement of 8.5 million Class B shares, and concerns tied to a delayed Form 10‑K.
• Robbins Geller, Pomerantz, and Hagens Berman are soliciting investors for the lead‑plaintiff process, with the class period spanning January 27, 2026 to noon ET on January 29, 2026.
