Context

• The 100,000-share sale was executed under a pre-established 10b5-1 plan (adopted May 23, 2026), which generally indicates a pre-planned sale schedule rather than an ad-hoc market-timing decision.
• The grants (RSUs, stock award, and options) are awards — not open-market purchases — and will vest over time per the schedules noted above. The 4,547-share disposal was a tax-withholding event (common when RSUs or awards settle).
• For retail investors: awards increase future share exposure if they vest, while sales under a 10b5-1 plan are often routine. The filing is factual and does not indicate management’s intent beyond the transactions disclosed.
