STAA insider ownership: who sold, why, and what they still hold

What stands out

Tax withholding outweighed market sales: the company withheld $2.4M of officers' and directors' shares for taxes, against $0 sold on the open market. The largest was Warren Foust ($1.0M withheld).Largest withholding, Jul 31, 2026

No officer or director sold shares in this period. 11 are left out

Left out: Christopher Wang, Warren Foust, Nathaniel Sisitsky, Wei Jiang, Richard LeBuhn, Magda Michna, Deborah Andrews, Elizabeth Lin, Lilian Zhou, Arthur Butcher and Lou Silverman (share of stake is being verified).

Disclosed company stock is not an insider's whole wealth.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Known gaps and uncertainty11 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Staar Surgical Co are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology736 filings on record, 35 filed in the 12-month period, and how we read them

All 736 Forms 3, 4 and 5 on record for Staar Surgical Co (SEC CIK 718937), filed from May 30, 2003 to Aug 18, 2026; 35 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 13, 2026. Prices are the ones reported in each filing, often weighted averages.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
