Section 16 (SEC Forms 3/4/5) only — US SEC filers. A role held without a Section-16 filing obligation does not appear here, and this is not a proxy-statement biography.
The officer/director ROSTER is rebuilt from filings 2015-07-01 → 2026-06-30; the TRANSACTION record reaches back to the store's start. An issuer with transactions but no roster row is one the person filed at before that window.
Titles are as filed on the person's most recent form at that issuer — a departure shows only when they next file, so check 'last filed'.
Open-market totals count purchases (P) and sales (S) only, through the same cleaned engine as the OWN tab and the screener, so the three never disagree. Rows the price guards removed are still listed below with the reason.
Names are as entered by the filer and drift between filings; every spelling on record is listed rather than normalised into one invented form.
Nothing here infers motive; we have no 10b5-1 plan dates, so a scheduled sale and a discretionary one look the same here.
