"% of total stake" is the shares in this event against all the vested shares the person held that day, across every share class and holding entity, after that day's vesting. "n/a" means the person's holdings don't reconcile, or the row is a purchase. "Holdings record incomplete" means more shares were sold than the filings show the person held that day, so a percentage would be wrong.

Is this normal? Less than usual: no sales, against a 3-year average of 1.4K shares a year. 0 insiders sold; the average is 1 a year. Year by year

22 of 22 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (16 exactly, 6 with a minor or footnoted difference). Percentages cover 15 of 22 officers and directors. Left out: Julie Holzrichter, Khandpur Ashish, John Richardson, Bradley Halverson, Nneka Rimmer, Peter Oppenheimer and Andrew Novotny (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

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.

Sources and methodology241 filings from SEC EDGAR, and how we read them

All 241 Forms 3, 4 and 5 filed for Constellation Energy (SEC CIK 1868275) from Feb 10, 2022 to Oct 2, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages. 1 filing was left out because Constellation Energy filed them as an owner of another company's stock.

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".
