WSTWest Pharmaceutical Services · Insider ownership research

West Pharmaceutical Services insiders sold $6.6M in the past 12 months. How much of their stake is that?

About 0.4% 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, through vesting or option exercises.

"% 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.

Who sold, and how much of their stake

Officers and directors, past 12 months. Each bar is 100% of that person's own stake; not comparable between people. The stake is the vested shares held at the start of the period (Oct 9, 2025); the gold part is what they sold.

Common questions

Is the West Pharmaceutical Services CEO selling stock?

No. Eric Green reported no open-market sales in the past 12 months.

Why are West Pharmaceutical Services insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 41% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 59% had no disclosed plan. A trading plan schedules sales in advance.

Are any West Pharmaceutical Services insiders buying?

No. Officers and directors reported no purchases in the past 12 months.

How much of their stake did West Pharmaceutical Services insiders sell?

About 0.4% 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, through vesting or option exercises. That covers the 12 months to Oct 9, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

15 of 20 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (6 exactly, 9 with a minor or footnoted difference). For 5 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 13 of 20 officers and directors. Left out: Eric Green, Annette Favorite, Paolo Pucci, Molly Joseph and Shane Campbell (holdings couldn't be fully reconciled); Robert McMahon and Norman Finch Jr. (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$6.6M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $6.6M across 19,372 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 ($3.9M), including tax-related sales outside a plan.

No plan disclosed · $3.9M

Sales with no 10b5-1 plan and no tax reference in the filing. $3.6M of it is Annette Favorite. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Annette Favorite, Sep 8, 2026

Taxes

6,945 shares ($2.0M) 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.

Known gaps and uncertainty5 insiders whose holdings couldn't be fully reconciled

Inferred typo: the share class "Common stocks" 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 (Richard Luzzi, 31,340 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 methodology2,634 filings from SEC EDGAR, and how we read them

All 2,634 Forms 3, 4 and 5 filed for West Pharmaceutical Services (SEC CIK 105770) from Jul 1, 2003 to Oct 2, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages.

Probable 2-for-1 stock split on or before Oct 6, 2004 (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 Sep 27, 2013 (first filing that shows post-split balances). 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".
