"% 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.
Percentages cover 14 of 21 officers and directors. 7 are left out Disclosed company stock is not an insider's whole wealth.i
Left out: Paul Stebbins (most holdings were last confirmed in 2019); Markus Gloeckler, Kuntal Verma, Patrick Buehler and Samantha Sloan (most of their shares vested during the period, so a percentage would mislead); Nathan Theurer and Curtis Morgan (held no vested shares at the start).
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.
Officers and directors, Oct 2025 to Oct 2026. Each sale is counted once: under a disclosed plan, else to cover taxes, else no plan disclosed.
Michael Ahearn reported no open-market sales in the past 12 months. Large shareholders and the funds or companies that board members represent are not part of management, so they are left out of the figures above.
Yes. Mark Widmar sold 40K shares ($9.0M, 49% of starting holdings) in the past 12 months, 63% of it under a trading plan disclosed in the filings.
Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 70% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 23% were to cover taxes and 7% had no disclosed plan. A trading plan schedules sales in advance.
No. Officers and directors reported no purchases in the past 12 months.
About 29% overall. As a group they still hold 79% of their starting shares. The biggest individual seller, Georges Antoun, gave up 78% of starting holdings. 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.

Vested shares across all share classes, held directly and through trusts, LLCs and family members, as reported on SEC Forms 3, 4 and 5. Unvested awards and options are never counted as owned shares.

21 of 21 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (20 exactly, 1 with a minor or footnoted difference). Percentages cover 14 of 21 officers and directors. Left out: Paul Stebbins (most holdings were last confirmed in 2019); Markus Gloeckler, Kuntal Verma, Patrick Buehler and Samantha Sloan (most of their shares vested during the period, so a percentage would mislead); Nathan Theurer and Curtis Morgan (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.
Officer and director open-market sales: $43.4M across 188,420 shares. Plan status and stated purpose are separate questions, and a sale can have both.
The lighter segment is sales with no plan disclosed in the filing ($13.0M), including tax-related sales outside a plan.
Sales with no 10b5-1 plan and no tax reference in the filing. $1.8M of it is Paul Stebbins. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Paul Stebbins, Nov 7, 2025
$10.3M of sales (23.6%) cite tax obligations in their footnotes, $276K of them also under a plan. Separately, 332 shares ($75K) were withheld by the company for taxes, which isn't a market sale. Example: Samantha Sloan, Aug 17, 2026
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.
Every officer and director reconciles for this period.
Jason Dymbort: minor difference of -8,473 shares. Difference is stated in footnotes (unreported vesting, exempt acquisition or transfer).
External context: we only cite outside events when a documented connection exists. None is shown for this period.
All 1,959 Forms 3, 4 and 5 filed for First Solar (SEC CIK 1274494) from Nov 16, 2006 to Oct 2, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages. 2 filings were left out because First Solar filed them as an owner of another company's stock.
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".
