Sep 23, 20265 executives had 10K shares ($915K) withheld by the company for taxes (not a market sale). That is between 0.7% and 1.6% of each person's total stake held that day (not shown for 2 people: the holdings on record that day are incomplete; why). 23K shares came in from vesting or option exercises the same day, so their combined holdings rose by 13K net.

"% 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 5-year average of 6.8K shares a year. 0 insiders sold; the average is 1 a year. Year by year

14 of 18 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (12 exactly, 2 with a minor or footnoted difference). For 4 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 7 of 18 officers and directors. Left out: Walter Hulse III, Julie Edwards and Lori Gobillot (most holdings were last confirmed in 2023); Mary Spears, Lyndon Taylor, Randy Lentz and Brian Derksen (holdings couldn't be fully reconciled); Pattye Moore (most holdings were last confirmed in 2017); Gerald Smith, Precious Owodunni and Mark McCollum (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

Is this normal? Selling year by year5 earlier years to compare with

Less than usual: no sales, against a 5-year average of 6.8K shares a year. 0 insiders sold; the average is 1 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.

Known gaps and uncertainty4 insiders whose holdings couldn't be fully reconciled

Mary Spears: holdings couldn't be fully reconciled (difference of 698 shares). Balance changed with no matching transaction and no footnote: +332.207 shares on Feb 22, 2026 (401(k)). Filing, Feb 22, 2026

Lyndon Taylor: holdings couldn't be fully reconciled (difference of 740 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +468.394 shares on Sep 23, 2026 (Direct). Filing, Sep 23, 2026

Footnote: "Restricted units awarded under the Issuer's Equity Incentive Plan on 9/23/25. Twenty percent of the award vested on 9/23/2026. During the vesting period, the award was credited with dividend equivalents that were paid out in shares of common stock at the time the underlying units vested and were issued. The award and credited dividend equivalents were payable in one share of the Issuer's common stock for each vested restricted unit, including additional restricted units resulting from dividend equivalents."

Randy Lentz: holdings couldn't be fully reconciled (difference of 259 shares). Balance changed with no matching transaction and no footnote: +258.731 shares on Jan 30, 2026 (Direct). Filing, Jan 30, 2026

Sources and methodology2,036 filings from SEC EDGAR, and how we read them

All 2,036 Forms 3, 4 and 5 filed for Oneok (SEC CIK 1039684) from Oct 11, 2002 to Sep 24, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 6 filings were left out because Oneok filed them as an owner of another company's stock. 53 older filings exist only on paper and could not be read.

Probable 2-for-1 stock split on or before Jun 15, 2012 (first filing that shows post-split balances). Splits aren't reported as transactions; 44 holding lines changed by exactly this ratio, so earlier share counts are restated.

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".
