Common questions

Is the GameStop Corp. CEO selling stock?

No. Ryan Cohen reported no open-market sales in the past 12 months.

Why are GameStop Corp. insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 35% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 51% were to cover taxes and 15% had no disclosed plan. A trading plan schedules sales in advance.

Are any GameStop Corp. insiders buying?

Yes. 5 officers or directors reported 15 purchases in the past 12 months (Form 4 code P, which includes private purchases).

How much of their stake did GameStop Corp. insiders sell?

About 8.6% overall. As a group they ended with more shares than they started with. The biggest individual seller, Mark Robinson, gave up 45% of starting holdings. These figures leave out Ryan Cohen, the largest holder (holdings couldn't be fully reconciled). 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.

6 of 7 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (6 exactly, 0 with a minor or footnoted difference). For 1 we show sales but not holdings; the ! icon on that row explains why. Percentages cover 5 of 7 officers and directors. Left out: Ryan Cohen (holdings couldn't be fully reconciled); Nat Turner (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$1.8M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $1.8M across 78,083 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

The lighter segment is sales with no plan disclosed in the filing ($1.1M), including tax-related sales outside a plan.

No plan disclosed · $256K

Sales with no 10b5-1 plan and no tax reference in the filing. $256K of it is Mark Robinson. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Mark Robinson, Jan 12, 2026

Taxes

$1.2M of sales (69.6%) cite tax obligations in their footnotes, $336K of them also under a plan. Example: Mark Robinson, Oct 1, 2026

Purchases · 5 buyers (15 trades)

5 officers and directors bought shares in this period, in 15 trades(Form 4 code P). Across all their filings on record there are 51 purchase trades.

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 uncertainty1 insider whose holdings couldn't be fully reconciled

Ryan Cohen: holdings couldn't be fully reconciled (difference of 37,347,842 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +37,347,842 shares on Jan 20, 2026 (Direct). Filing, Jan 20, 2026

Footnote: "Represents a weighted average price. These shares were purchased in multiple transactions at prices ranging from $20.8071 to $21.1997, inclusive. The Reporting Person undertakes to provide the Issuer, any security holder of the Issuer or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares purchased at each separate price within the range set forth in this footnote."

Inferred rename: "See Exhibit 5" is treated as the same holder as "See Exhibit 6", because the old name was never reported again and the new one opened with the same balance (80 shares). Old name, new name

Inferred rename: "See Exhibit 6" is treated as the same holder as "See Exhibit 7", because the old name was never reported again and the new one opened with the same balance (80 shares). Old name, new name

Inferred rename: "See Exhibit 8" is treated as the same holder as "See Exhibit 9", because the old name was never reported again and the new one opened with the same balance (80 shares). Old name, new name

Inferred rename: "See Exhibit 9" is treated as the same holder as "See Exhibit 10", because the old name was never reported again and the new one opened with the same balance (80 shares). Old name, new name

Inferred rename: the share class "Common Stock, par value $0.001 per share" is treated as the same class as "Class A Common Stock, par value $0.001 per share" on 1 holding line, because the old title was never reported again on those lines and each balance carried over exactly. Example (Edward Volkwein, 161,600 shares): old title, new title

Inferred rename: the share class "Common stock, par value $.001 per share" is treated as the same class as "Class A Common stock, par value $.001 per share" on 1 holding line, because the old title was never reported again on those lines and each balance carried over exactly. Example (Susan Kim, 72,926,984 shares): old title, new title

Inferred rename: the share class "Common Stock" is treated as the same class as "Class A Common Stock" on 1 holding line, because the old title was never reported again on those lines and each balance carried over exactly. Example (Lawrence Cheng, 12,000 shares): old title, new title

External context: we only cite outside events when a documented connection exists. None is shown for this period.

Sources and methodology730 filings from SEC EDGAR, and how we read them

All 730 Forms 3, 4 and 5 filed for GameStop Corp. (SEC CIK 1326380) from Oct 11, 2005 to Oct 5, 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 GameStop Corp. filed them as an owner of another company's stock.

Probable 2-for-1 stock split on or before Mar 6, 2007 (first filing that shows post-split balances). Splits aren't reported as transactions; 10 holding lines changed by exactly this ratio, so earlier share counts are restated.

Probable 4-for-1 stock split on or before Jul 21, 2022 (split date stated in a footnote). Splits aren't reported as transactions; 6 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".
