Common questions

Is the Carlisle Companies Inc CEO selling stock?

Yes. Christian Koch sold 36K shares ($15.0M) in the past 12 months, none of it under a trading plan disclosed in the filings.

Why are Carlisle Companies Inc 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 Carlisle Companies Inc insiders buying?

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

What explains the selling$28.2M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $28.2M across 68,522 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $28.2M

Sales with no 10b5-1 plan and no tax reference in the filing. $15.0M of it is Christian Koch. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Christian Koch, Feb 10, 2026

Taxes

18,238 shares ($6.2M) 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 uncertainty22 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Carlisle Companies Inc are held back until that check is finished. Sales, proceeds, plan and tax status, titles and dates come straight from individual filings and are complete.

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

Sources and methodology1,312 filings on record, 65 filed in the 12-month period, and how we read them

All 1,312 Forms 3, 4 and 5 on record for Carlisle Companies Inc (SEC CIK 790051), filed from Aug 12, 2003 to Sep 11, 2026; 65 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 16, 2026. Prices are the ones reported in each filing, often weighted averages.

Probable 2-for-1 stock split on or before Jun 13, 2007 (first filing that shows post-split balances). Splits aren't reported as transactions; 8 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".
