Common questions

Is the MP Materials Corp. CEO selling stock?

Yes. James Litinsky sold 2.12M shares ($137M) in the past 12 months, 28% of it under a trading plan disclosed in the filings.

Why are MP Materials Corp. insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 31% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 69% had no disclosed plan. A trading plan schedules sales in advance.

Are any MP Materials Corp. insiders buying?

Yes. 1 officer or director reported 2 purchases in the past 12 months (Form 4 code P; rows the filings describe as reinvested dividends, plan purchases, private deals or moves into the person's own trust are not counted).

What explains the selling$147M of sales by plan status, purpose, seller and month

No plan disclosed · $101M

Sales with no 10b5-1 plan and no tax reference in the filing. $98.8M of it is James Litinsky. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: James Litinsky, Dec 5, 2025

Taxes

250,291 shares ($15.7M) 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 uncertainty11 officers and directors not confirmed

Holdings and share of stake are being verified. Balances, unit counts and every share-of-stake figure for MP Materials Corp. 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 methodology283 filings on record, 39 filed in the 12-month period, and how we read them

All 283 Forms 3, 4 and 5 on record for MP Materials Corp. (SEC CIK 1801368), filed from Apr 29, 2020 to Sep 30, 2026; 39 of them were filed in the 12 months this page covers, retrieved from SEC EDGAR on Oct 13, 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".
