Why are they buying?

AI · discretionary · catalyst credible · documented

The open-market purchases by the CEO, CFO, and a director follow recent corporate milestones, including a $35 million private placement that eliminated going concern doubts, second-quarter financial results, and strategic additions to the Board of Directors.

Form 4 filings confirm open-market stock purchases by CEO Jaymes Winters, CFO Vlad Prantsevich, and Director Karin-Joyce Tjon in September 2026, closely trailing press releases detailing business developments and board governance updates.
