Mosaic Company insiders sold $509K in the past 12 months. How much of their stake is that?

"% 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.

Is this normal? Less than usual: about a quarter of the 5-year average. 1 insider sold; the average is 2 a year. Year by year

What stands out

Jody Kuzenko bought 685 shares for $17K, first on Nov 11, 2025. These are the first by current officers or directors since May 6, 2022.Purchase, Nov 11, 2025
Tax withholding outweighed market sales: the company withheld $891K of officers' and directors' shares for taxes, against $509K sold on the open market. The largest was Bruce Bodine ($206K withheld).Largest withholding, Mar 9, 2026

Percentages cover all 18 officers and directors. Disclosed company stock is not an insider's whole wealth.

Common questions

Is the Mosaic Company CEO selling stock?

No. Bruce Bodine reported no open-market sales in the past 12 months.

Why are Mosaic Company 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 Mosaic Company insiders buying?

Yes. 1 officer or director reported 1 purchase in the past 12 months (Form 4 code P, which includes private purchases).

How much of their stake did Mosaic Company insiders sell?

About 2.5% overall. As a group they ended with more shares than they started with. The biggest individual seller, Walter Precourt III, gave up 18% of starting holdings. 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.

18 of 18 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (16 exactly, 2 with a minor or footnoted difference). Percentages cover all 18 officers and directors. "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$509K of sales by plan status, purpose, seller and month

Officer and director open-market sales: $509K across 23,000 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

No plan disclosed · $509K

Sales with no 10b5-1 plan and no tax reference in the filing. $509K of it is Walter Precourt III. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Walter Precourt III, Aug 19, 2026

Taxes

33,211 shares ($891K) were withheld by the company for taxes, which isn't a market sale.

Purchases · 1 buyer (1 trade)

1 officer or director bought shares in this period, in 1 trade(Form 4 code P). Across all their filings on record there are 15 purchase trades.

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 uncertaintyEvery officer and director reconciles

Every officer and director reconciles for this period.

Gregory Ebel: minor difference of 71 shares. Difference is under 0.5% of holdings.

Bruce Bodine: minor difference of 22 shares. Difference is under 0.5% of holdings.

Inferred rename: "GNS I (U.S.) Corp" is treated as the same holder as "Cargill GNS I, LLC", because the old name was never reported again and the new one opened with the same balance (30,155,221 shares). Old name, new name

Inferred rename: "Cargill Fertilizer Inc" is treated as the same holder as "Cargill CFI, LLC", because the old name was never reported again and the new one opened with the same balance (243,972,618 shares). Old name, new name

Inferred typo: the share class "Commonn Stock" 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 McLellan, 44,991 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 methodology1,079 filings from SEC EDGAR, and how we read them

All 1,079 Forms 3, 4 and 5 filed for Mosaic Company (SEC CIK 1285785) from Oct 22, 2004 to Oct 2, 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".
