Richtech Robotics Inc (NASDAQ:RR) shares are trading lower Friday morning, extending Thursday’s selloff after a critical Hunterbrook Media report. The slide comes as investors reassess the company's recently announced relationship with Microsoft. Here’s what investors need to know.

• Richtech Robotics shares are sliding. What’s pressuring RR stock?

Microsoft Collaboration Disputed By Hunterbrook Report

Hunterbrook says Microsoft described Richtech's role as a standard AI Co-Innovation Lab customer engagement with "no commercial element," contradicting Richtech's earlier claim of a "close collaboration."

The report argues that excitement over the announcement lifted Richtech's market value by more than $370 million before the company revealed a $38.7 million private placement the next morning, fueling concern investors overestimated the tie-up.

Filing Delay Weighs On Sentiment

The report also highlights Richtech's delayed 10-K filing, warning it could complicate fundraising and potentially invite Nasdaq deficiency notices. The filing shows fiscal 2025 revenue of about $5 million against a net loss near $15.8 million, underscoring heavy cash burn and dependence on issuing new shares.

Hunterbrook's critique also follows earlier claims from short seller Capybara Research, which previously labeled Richtech a "China Hustle" and alleged rebranded robots and fabricated partnerships.

Hunterbrook Capital, an affiliate of Hunterbrook Media, disclosed a short position in RR, further pressuring the stock.
