About 13% overall. As a group they still hold 95% of their starting shares. The biggest seller whose stake can be measured, Allen Behr, gave up 58% of starting holdings.
No officer or director trades were reported for the past 30 days. The most recent before that:
| Who | Shares | Price | % of total stake | Total stake after | Trade date | Filed |
|---|---|---|---|---|---|---|
| Leon Topalian Chair and CEO | 1,800 | n/a | 1.3% | 138K | Aug 17, 2026 | Aug 19, 2026 |
"% 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.
Percentages cover 22 of 23 officers and directors. Left out: Leon Topalian (most of their shares vested during the period, so a percentage would mislead). Disclosed company stock is not an insider's whole wealth.
Officers and directors, past 12 months. Each bar is the insider's vested stake at the start of the period (Oct 8, 2025). The gold part is what they sold.
Officers and directors, Oct 2025 to Oct 2026. Each sale is counted once: under a disclosed plan, else to cover taxes, else no plan disclosed.
Yes. Leon Topalian sold 95K shares ($21.5M) in the past 12 months, none of it under a trading plan disclosed in the filings.
Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 0% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 100% had no disclosed plan. A trading plan schedules sales in advance.
No. Officers and directors reported no purchases in the past 12 months.
About 13% overall. As a group they still hold 95% of their starting shares. The biggest seller whose stake can be measured, Allen Behr, gave up 58% of starting holdings. That covers the 12 months to Oct 8, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

23 of 23 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (22 exactly, 1 with a minor or footnoted difference). Percentages cover 22 of 23 officers and directors. Left out: Leon Topalian (most of their shares vested during the period, so a percentage would mislead). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.
Officer and director open-market sales: $57.0M across 258,510 shares. Plan status and stated purpose are separate questions, and a sale can have both.
Sales with no 10b5-1 plan and no tax reference in the filing. $21.5M of it is Leon Topalian. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: David Sumoski, Apr 30, 2026
79,022 shares ($18.9M) were withheld by the company for taxes, which isn't a market sale.

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.
Every officer and director reconciles for this period.
Leon Topalian: minor difference of 3 shares. Difference is under 0.5% of holdings.
Inferred rename: "Daughter (ursala)" is treated as the same holder as "Daughter (Ursula)", because the old name was never reported again and the new one opened with the same balance (800 shares). Old name, new name
External context: we only cite outside events when a documented connection exists. None is shown for this period.
All 1,136 Forms 3, 4 and 5 filed for Nucor (SEC CIK 73309) from Aug 13, 2003 to Aug 19, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages.
Probable 2-for-1 stock split on or before Oct 15, 2004 (split date stated in a footnote). Splits aren't reported as transactions; 14 holding lines changed by exactly this ratio, so earlier share counts are restated.
Probable 2-for-1 stock split on or before May 31, 2006 (split date stated in a footnote). Splits aren't reported as transactions; 12 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".
