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

What stands out

Two directors sold $3.5M with no disclosed plan: Rita Heise ($1.8M) and Reyne Wisecup ($1.7M). The filings don't state a reason.Rita Heise: largest such sale, Aug 5, 2026 · Reyne Wisecup: largest such sale, Mar 5, 2026

Four directors bought shares: Hsenghung HSU (2K shares, $83K), Stephen Eastman (1K shares, $41K) and Daniel Johnson (1K shares, $40K), plus 1 more.Hsenghung HSU: purchase, Oct 16, 2025 · Stephen Eastman: purchase, Nov 12, 2025 · Daniel Johnson: purchase, Nov 17, 2025

Selling rose in the last 90 days but the year remains well below the 5-year average: officers and directors sold 50K shares, against an average of 17K per 90 days earlier in the period. Most of it was Rita Heise (35K shares in the last 90 days) and Donnalee Papenfuss (9.3K shares in the last 90 days); 0% of these sales were under disclosed plans.Rita Heise: largest recent sale, Aug 5, 2026 · Donnalee Papenfuss: largest recent sale, Aug 13, 2026

Percentages cover 12 of 21 officers and directors. 9 are left out

Left out: Michael Ancius and Rita Heise (holdings couldn't be fully reconciled); James Jansen (most holdings were last confirmed in 2020); Reyne Wisecup and Donnalee Papenfuss (most of their shares vested during the period, so a percentage would mislead); Noelle Oas, Irene Quarshie, Brady Ericson and Max Tunnicliff (held no vested shares at the start).

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

Who sold, and how much of their stake

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.

Common questions

Is the Fastenal CEO selling stock?

No. Daniel Florness reported no open-market sales in the past 12 months.

Why are Fastenal insiders selling?

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.

Are any Fastenal insiders buying?

Yes. 4 officers or directors reported 5 purchases in the past 12 months (Form 4 code P, which includes private purchases).

How much of their stake did Fastenal insiders sell?

About 1.8% overall. As a group they ended with more shares than they started with. The biggest seller whose stake can be measured, Scott Satterlee, gave up 32% 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.

Reconciliation: minor difference of 345 shares. Difference is stated in footnotes (unreported vesting, exempt acquisition or transfer).

19 of 21 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (18 exactly, 1 with a minor or footnoted difference). For 2 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 12 of 21 officers and directors. Left out: Michael Ancius and Rita Heise (holdings couldn't be fully reconciled); James Jansen (most holdings were last confirmed in 2020); Reyne Wisecup and Donnalee Papenfuss (most of their shares vested during the period, so a percentage would mislead); Noelle Oas, Irene Quarshie, Brady Ericson and Max Tunnicliff (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$5.0M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $5.0M across 103,106 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $5.0M

Sales with no 10b5-1 plan and no tax reference in the filing. $1.8M of it is Rita Heise. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Reyne Wisecup, Mar 5, 2026

Purchases · 4 buyers (5 trades)

4 officers and directors bought shares in this period, in 5 trades(Form 4 code P). Across all their filings on record there are 154 purchase trades.

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

Less than usual: about one-fifth of the 5-year average. 5 insiders sold; the average is 8 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 uncertainty2 insiders whose holdings couldn't be fully reconciled

Michael Ancius: holdings couldn't be fully reconciled (difference of -2,000 shares). Balance changed without a matching transaction, and the footnote does not state the amount: -2,000 shares on Oct 14, 2025 (Direct). Filing, Oct 14, 2025

Footnote: "On May 22, 2019 and May 21, 2025, the Common Stock of Fastenal Company split 2-for-1 and the amounts reported have been adjusted to reflect the stock split. | This amount includes 42,168 shares held in a revocable trust over which the reporting person and his wife share voting and investment power and 12,022 shares held in the reporting person's self-directed IRA."

Rita Heise: holdings couldn't be fully reconciled (difference of -20,000 shares). Balance changed without a matching transaction, and the footnote does not state the amount: -20,000 shares on Aug 5, 2026 (Direct). Filing, Aug 5, 2026

Footnote: "On May 21, 2025, the Common Stock of Fastenal Company spit 2-for-1 and the amounts reported have been adjusted to reflect the stock split."

Donnalee Papenfuss: minor difference of 345 shares. Difference is stated in footnotes (unreported vesting, exempt acquisition or transfer).

Inferred rename: "401(K) Plan" is treated as the same holder as "Held in issuer 401(K) Plan", because the old name was never reported again and the new one opened with the same balance (3,064 shares). Old name, new name

Inferred rename: "Spouse" is treated as the same holder as "reporting person", because the old name was never reported again and the new one opened with the same balance (4,780,800 shares). Old name, new name

Inferred rename: "Revocable living trust" is treated as the same holder as "trust", because the old name was never reported again and the new one opened with the same balance (3,191,232 shares). Old name, new name

Inferred rename: "Spouse" is treated as the same holder as "Owned by Spouse", because the old name was never reported again and the new one opened with the same balance (3,357,280 shares). Old name, new name

Inferred rename: "Custodian for Minor Children" is treated as the same holder as "Held in custodian account for minor children", because the old name was never reported again and the new one opened with the same balance (320 shares). Old name, new name

Inferred rename: "Held in custodian account for minor children" is treated as the same holder as "Held in custodian account for children", because the old name was never reported again and the new one opened with the same balance (320 shares). Old name, new name

Inferred rename: "Held in custodial account for Son" is treated as the same holder as "Held in custodian account for Son", because the old name was never reported again and the new one opened with the same balance (628 shares). Old name, new name

Inferred rename: "Owned by father" is treated as the same holder as "father", because the old name was never reported again and the new one opened with the same balance (2,504 shares). Old name, new name

Inferred typo: the share class "Common Stcok" is treated as the same class as "Common Stock" on 1 holding line, because the two spellings are nearly identical and each balance carried over exactly. Example (Nicholas Lundquist, 112,000 shares): old title, new title

Sources and methodology1,065 filings from SEC EDGAR, and how we read them

All 1,065 Forms 3, 4 and 5 filed for Fastenal (SEC CIK 815556) from Jul 3, 2003 to Aug 17, 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 Nov 17, 2005 (first filing that shows post-split balances). Splits aren't reported as transactions; 11 holding lines changed by exactly this ratio, so earlier share counts are restated.

Probable 2-for-1 stock split on or before Jul 21, 2011 (first filing that shows post-split balances). Splits aren't reported as transactions; 7 holding lines changed by exactly this ratio, so earlier share counts are restated.

Probable 2-for-1 stock split on or before May 22, 2019 (split date stated in a footnote). Splits aren't reported as transactions; 20 holding lines changed by exactly this ratio, so earlier share counts are restated.

Probable 2-for-1 stock split on or before May 21, 2025 (split date stated in a footnote). Splits aren't reported as transactions; 13 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".
