What stands out

Outside holder FLUOR CORP, a 10% owner and not part of management, sold $1.83B of stock, 93% of the starting stake.Largest sale, Feb 13, 2026

Jose Reyes Jr. sold 26K shares (5.0% of starting holdings), but 73K more vested, so the stake grew (from 516K to 564K).Largest sale, Mar 2, 2026

Percentages cover 6 of 18 officers and directors. 12 are left out

Left out: Carl Fisher, Clayton Scott and Robert Hamady (most of their shares vested during the period, so a percentage would mislead); Shinji Fujino (holdings couldn't be fully reconciled); John Hopkins, Jacqueline Engel, Shahram Ghasemian, James Canafax, David Tonnel, William Cooper, Dale Klein and Stuart Harshaw (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.

Details

Common questions

Is the NuScale Power CEO selling stock?

Yes. John Hopkins sold 83K shares ($1.0M) in the past 12 months, none of it under a trading plan disclosed in the filings.

Why are NuScale Power insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 43% of sales by value ran under 10b5-1 trading plans disclosed in the filings, 54% were to cover taxes and 4% had no disclosed plan. A trading plan schedules sales in advance.

Are any NuScale Power insiders buying?

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

How much of their stake did NuScale Power insiders sell?

About 3.3% overall. As a group they ended with more shares than they started with. 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.

17 of 18 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (15 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 6 of 18 officers and directors. Left out: Carl Fisher, Clayton Scott and Robert Hamady (most of their shares vested during the period, so a percentage would mislead); Shinji Fujino (holdings couldn't be fully reconciled); John Hopkins, Jacqueline Engel, Shahram Ghasemian, James Canafax, David Tonnel, William Cooper, Dale Klein and Stuart Harshaw (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$4.8M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $4.8M across 392,081 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $2.1M · 43%

57%

The lighter segment is sales with no plan disclosed in the filing ($2.8M), including tax-related sales outside a plan.

No plan disclosed · $177K

Sales with no 10b5-1 plan and no tax reference in the filing. $177K of it is Shinji Fujino. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Shinji Fujino, Aug 18, 2026

Taxes

$2.6M of sales (53.6%) cite tax obligations in their footnotes. Example: Robert Hamady, Aug 27, 2026

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

Shinji Fujino: holdings couldn't be fully reconciled (difference of 8,681 shares). Balance changed without a matching transaction, and the footnote does not state the amount: +17,362 shares on May 29, 2026 (Direct). Filing, May 29, 2026

Footnote: "The amount of securities beneficially owned has been corrected in this Form 4 Amendment to reflect that the transaction reported on June 2, 2026, was an acquisition rather than a disposition. The previously reported Form 4 incorrectly reduced the Reporting Person's holdings by 8,681 shares. The Reporting Person's beneficial ownership following the transaction is 45,923 shares."

Kent Kresa: minor difference of 3,946 shares. Difference is stated in footnotes (unreported vesting, exempt acquisition or transfer).

Alan Boeckmann: minor difference of 3,470 shares. Difference is stated in footnotes (unreported vesting, exempt acquisition or transfer).

Inferred rename: "daughter" is treated as the same holder as "daughter, Katherine Mundy", because the old name was never reported again and the new one opened with the same balance (72 shares). Old name, new name

Inferred rename: "son" is treated as the same holder as "daughter", because the old name was never reported again and the new one opened with the same balance (1,732 shares). Old name, new name

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

Sources and methodology293 filings from SEC EDGAR, and how we read them

All 293 Forms 3, 4 and 5 filed for NuScale Power (SEC CIK 1822966) from Nov 23, 2020 to Oct 5, 2026, retrieved from SEC EDGAR on Oct 8, 2026. Prices are the ones reported in each filing, often weighted averages.

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".
