"% 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 19 of 20 officers and directors. Left out: Carole Brown (held no vested shares at the start). 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. Anthony Smurfit sold 40K shares ($2.1M, 1.3% of starting holdings) 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 1.4% overall. As a group they ended with more shares than they started with. 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.

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.

20 of 20 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (20 exactly, 0 with a minor or footnoted difference). Percentages cover 19 of 20 officers and directors. Left out: Carole Brown (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: $3.4M across 65,562 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. $2.1M of it is Anthony Smurfit. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Anthony Smurfit, Feb 19, 2026
141,619 shares ($6.8M) 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.
Inferred rename: "Shares owned by spouse" is treated as the same holder as "Shares held by spouse", because the old name was never reported again and the new one opened with the same balance (3,188 shares). Old name, new name
External context: we only cite outside events when a documented connection exists. None is shown for this period.
All 285 Forms 3, 4 and 5 filed for Smurfit Westrock plc (SEC CIK 2005951) from Jul 9, 2024 to Sep 14, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages.
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".
