Williams Companies insiders sold $11.1M in the past 12 months. How much of their stake is that?

Vested shares across all share classes, held directly and through trusts, LLCs and family members, as reported on SEC Forms 3, 4 and 5. Unvested awards and options are never counted as owned shares.

26 of 26 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (26 exactly, 0 with a minor or footnoted difference). Percentages cover 25 of 26 officers and directors. Left out: Lloyd Helms Jr. (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

Officer and director open-market sales: $11.1M across 150,869 shares. Plan status and stated purpose are separate questions, and a sale can have both.

Sales by month

In line with the past 5 years. 7 insiders sold; the average is 3 a year.

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.

All 1,686 Forms 3, 4 and 5 filed for Williams Companies (SEC CIK 107263) from Sep 3, 2002 to Oct 2, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 161 filings were left out because Williams Companies filed them as an owner of another company's stock. 41 older filings exist only on paper and could not be read.

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".
