Common questions

Is the Artivion, Inc. CEO selling stock?

Yes. James Mackin sold 251K shares ($9.7M) in the past 12 months, 29% of it under a trading plan disclosed in the filings.

Why are Artivion, Inc. insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 24% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 42% were to cover taxes and 35% had no disclosed plan. A trading plan schedules sales in advance.

Are any Artivion, Inc. insiders buying?

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

What explains the selling$20.7M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $20.7M across 539,267 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $4.9M · 24%

76%

The lighter segment is sales with no plan disclosed in the filing ($15.9M), including tax-related sales outside a plan.

No plan disclosed · $7.2M

Sales with no 10b5-1 plan and no tax reference in the filing. $2.8M of it is Marshall Stanton. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: James Mackin, Aug 19, 2026

Taxes

$8.7M of sales (41.8%) cite tax obligations in their footnotes. Example: Andrew Green, Aug 14, 2026

Charitable gifts · 750 shares

Gifts the filings describe as charitable. Gifts are not sales and are not included in the sale totals.

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 uncertainty15 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for Artivion, 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 methodology1,507 filings on record, 61 filed in the 12-month period, and how we read them

All 1,507 Forms 3, 4 and 5 on record for Artivion, Inc. (SEC CIK 784199), filed from Jan 9, 1996 to Sep 11, 2026; 61 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. 2 filings were left out because Artivion, Inc. filed them as an owner of another company's stock. 195 older filings exist only on paper and could not be read.

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".
