Key Details

• Transaction date: 2026-02-19; Filing date (accession): 2026-02-20 (timely).
• Reported price: $0.00 for both acquisition and disposition (no cash paid or received per filing).
• Shares owned after the transaction: not disclosed in the Form 4 filing.
• Relevant footnotes: F1–F4 indicate these were RSUs (each converts to one share), vesting was accelerated due to her retirement, RSUs are exercisable at vesting with no set expiration, and 1,469 RSUs were cancelled on retirement.
• Filing timeliness: filed the next day; not marked late.

Context

• This was an RSU vest/convert event rather than an open‑market buy or sale. The simultaneous “disposed” entry at $0.00 commonly reflects withholding or internal settlement associated with RSU conversion (tax withholding or company delivery) rather than an open‑market sale; the Form 4 notes do not show a market sale. For retail investors, such conversion/withholding events are routine after vesting or retirement and do not necessarily signal a buy/sell decision by the insider.
