What the record says

Description, identity and filings, each with its source.

Every block cites its source. The colour of a finding marks its category — which document, who filed it — not how much it matters.

What the company does

MP Materials Corp. is an American rare-earth materials company headquartered in Las Vegas, Nevada. MP Materials owns and operates the Mountain Pass mine, the only operating rare earth mine and processing facility in the United States. MP Materials focuses its production on neodymium-praseodymium (NdPr), a rare-earth material used in high-strength permanent magnets that power the traction motors found in electric vehicles, robotics, wind turbines, drones, and other advanced motion technologies. MP Materials is listed on the New York Stock Exchange under the ticker symbol "MP". As of December 2021, JHL Capital Group, QVT Financial and CEO James Litinsky were the company's three largest shareholders, with about 7.7% of the company owned by Shenghe Resources, a Chinese company partly owned by the country's Ministry of Natural Resources. In July 2025, the United States Department of Defense announced a deal that would make it the largest shareholder of MP Materials.

The record reaches back to Jun 22, 20.

Corporate events are tracked from 2004-08-23, when the SEC renumbered 8-K items. Earlier filings use an incompatible numbering and are not classified here.

Ownership and control

Schedule 13D: stake and stated purpose

Filed by holders above 5% of a share class who cannot use the short form. It includes the investor's stated purpose: read it before assuming they seek influence.

Schedule 13G: short-form filing

The short form, for holders who meet specific requirements: institutional investors, passive investors without a control purpose, or exempt investors. Asset managers and index funds usually file it.

Structured 13D/G data starts 2023-12, when the SEC moved these filings to a machine-readable format. Earlier filings exist but are not parsed here.

  • No account

    This profile for every company we cover: closing prices with the record's facts on the curve, the SEC file in plain language, insider trades included, and links to its sector and exchange.

  • Pro

    What matters today, with its reason, is free with an account. Pro adds, in the profile, each company's notices and their explanation and the analysis of its insiders; in Radar, all the lenses, which notice each candidate carries, filters by notice type and «no dilution», and the cycle cohort filter; and in Watchlist, more companies and notice changes with their reason.

  • Pro+

    Adds the Lab: test a hypothesis on comparable cohorts before reusing it; and bring your lenses to Radar.

Are the prices real time?

No. It is one close per session, from the provider and with the date shown on the profile; it does not update during the trading day.

Which SEC documents appear here?

Those filed with the SEC by the company, its insiders and its major shareholders, within our coverage: periodic reports (10-K, 10-Q, 20-F), material events (8-K), proposed sale notices (Form 144), insider transactions (Form 4) and stakes above 5% (13D/13G). Each links to the original on EDGAR.

Why does a European company show no SEC records?

It depends on the company: some European issuers file a 20-F or 6-K with the SEC and others don't. The profile shows whatever is on record; when there is nothing, it says so rather than guessing why. Europe does not yet have a common filing archive like EDGAR in the United States. The EU will open its own, ESAP, in July 2027 (managers' transactions arrive in January 2028), and we plan to add it once it is available.

Before forming a view on a company,
