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

Who	Shares	Price	% of total stake	Total stake after	Trade date	Filed
Sanoke Viswanathan Chief Executive Officer, Director	8,065	$276.42	14%	50K	Sep 22, 2026	Sep 24, 2026

What stands out

Goran Skoko bought 500 shares for $126K, first on Nov 6, 2025.Purchase, Nov 6, 2025

Tax withholding outweighed market sales: the company withheld $2.9M of officers' and directors' shares for taxes, against $1.5M sold on the open market. The largest was Sanoke Viswanathan ($2.2M withheld).Largest withholding, Sep 22, 2026

Percentages cover 20 of 23 officers and directors. Left out: James McGonigle (most holdings were last confirmed in 2020); Gregory Moskoff (holdings couldn't be fully reconciled); Joshua Warren (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.

Laurie Siegel

Director

Common questions

Is the FactSet CEO selling stock?

No. Sanoke Viswanathan reported no open-market sales in the past 12 months.

Why are FactSet 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 FactSet insiders buying?

Yes. 1 officer or director reported 1 purchase in the past 12 months (Form 4 code P, which includes private purchases).

How much of their stake did FactSet insiders sell?

About 3.1% of the shares they held or received (after tax withholding) during the period. The usual measure, against starting holdings alone, can't be used here because most of the shares sold arrived during the period. 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.

The evidence

Who sold2 officers and directors: amount, % of holdings, trading plan

Who sold	Amount	% of holdings	Trading plan
Laurie Siegel Director	$762K 2.6K shares	61%† i † Most of the shares Laurie Siegel sold arrived during the period, so this is shares sold as a share of the 1K held at the start plus the 3.2K received, less 0 withheld by the company for taxes.	No plan disclosed
Malcolm Frank Director	$761K 2.6K shares	62%† i † Most of the shares Malcolm Frank sold arrived during the period, so this is shares sold as a share of the 879 held at the start plus the 3.3K received, less 0 withheld by the company for taxes.	No plan disclosed

22 of 23 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (20 exactly, 2 with a minor or footnoted difference). For 1 we show sales but not holdings; the ! icon on that row explains why. Percentages cover 20 of 23 officers and directors. Left out: James McGonigle (most holdings were last confirmed in 2020); Gregory Moskoff (holdings couldn't be fully reconciled); Joshua Warren (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$1.5M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $1.5M across 5,144 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $1.5M

Sales with no 10b5-1 plan and no tax reference in the filing. $762K of it is Laurie Siegel. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Laurie Siegel, Jan 8, 2026

Taxes

10,700 shares ($2.9M) were withheld by the company for taxes, which isn't a market sale.

Purchases · 1 buyer (1 trade)

1 officer or director bought shares in this period, in 1 trade(Form 4 code P). Across all their filings on record there are 5 purchase trades.

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

Less than usual: about one-twelfth of the 5-year average. 2 insiders sold; the average is 9 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 uncertainty1 insider whose holdings couldn't be fully reconciled

Gregory Moskoff: holdings couldn't be fully reconciled (difference of 45 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +24.818 shares on Nov 1, 2025 (Direct). Filing, Nov 1, 2025

Footnote: "Represents common stock received upon the vesting on November 1, 2025 of performance share units ("PSUs") granted on November 1, 2022."

Christopher Ellis: minor difference of 66 shares. Difference is under 0.5% of holdings.

Katherine Stepp: minor difference of 1 share. Difference is under 0.5% of holdings.

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

Sources and methodology1,200 filings from SEC EDGAR, and how we read them

All 1,200 Forms 3, 4 and 5 filed for FactSet (SEC CIK 1013237) from Mar 6, 1998 to Sep 30, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages. 143 older filings exist only on paper and could not be read.

Probable 3-for-2 stock split on or before Dec 21, 2005 (first filing that shows post-split balances). Splits aren't reported as transactions; 2 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".
