Context
This was an option exercise (Form 4 code M): the option was converted into common shares rather than sold immediately, so the filing shows an acquisition of shares and the cancellation of the derivative. Because of repurchase rights noted in the footnotes, shares issued on exercise may be subject to the company’s buyback if they were issued before vesting. As a reported 10% owner and via NR‑PRL Partners, this filing reflects an institutional/partner-held position rather than a routine executive open-market trade.
