Richtech Investors Face Friday Deadline in Lawsuit Over Microsoft Tie Claims

Overview

• Richtech shareholders face a lead‑plaintiff filing deadline Friday, April 3, as multiple investor-rights firms seek to represent a class.
• The suit centers on a January 27 press release touting a "hands‑on collaboration" with Microsoft’s AI Co‑Innovation Labs that sent the stock up about 30% on heavy trading.
• Richtech announced an at‑the‑market sale of 8.5 million Class B shares on January 28, a move plaintiff firms describe as dilutive to existing investors.
• Hunterbrook Media reported at noon on January 29 that Microsoft called the engagement a standard customer prototyping program with no commercial element, and the stock fell more than 20% that day and nearly 30% by January 30.
• No class has been certified, and law firms say they are probing whether investors who bought between January 27 and January 29 were misled, with some inviting whistleblowers to share non‑public information.
