Richtech Robotics Investors Face Lead-Plaintiff Push in Microsoft Misrepresentation Suits

Firms say Richtech overstated ties to Microsoft, which Microsoft described as a noncommercial lab program.

Overview

National shareholder firms, including Hagens Berman, DJS Law Group and The Schall Law Firm, are urging Richtech buyers to seek lead-plaintiff status before Friday’s April 3 court deadline.
The suits seek to represent investors who bought RR between January 27 and January 29, 2026 and allege violations of Exchange Act Sections 10(b) and 20(a) and SEC Rule 10b-5.
Richtech announced a “hands-on collaboration” with Microsoft on January 27, 2026, and the stock jumped about 30% on heavy trading that day.
The company disclosed an at-the-market sale of about 8.5 million Class B shares on January 28, a day after the collaboration announcement.
Hunterbrook’s January 29 reporting quoted Microsoft calling the engagement a standard, noncommercial lab program, and Richtech shares fell about 21% to close at $4.02; no class has been certified and investors are not represented unless they retain counsel.
