The shares were recorded at $0.67 each for a total of approximately $17,290 on August 20, 2026. This was a tax-withholding/net-share settlement (transaction code F), not an open-market sale driven by a new decision to liquidate holdings.

Context

• This was a routine net-share settlement to cover withholding tax on vested RSUs (common when equity awards vest). Such transactions do not necessarily signal a change in the insider’s view of the company since shares are surrendered to meet tax obligations rather than sold for cash on the open market.
