MP Materials Stock Is Having a Great Year so Far. Can the Run Continue?

MP Materials has experienced a 358% stock surge, driven by its unique position as the sole operational U.S. rare earth mine and strategic partnerships, including a DoD agreement for a new magnet manufacturing facility with a 10-year purchase commitment and a supply deal with Apple starting 2027. Despite these tailwinds for U.S. supply chain reshoring, the company faces significant challenges: it remains largely dependent on China for refined rare earth metals due to limited domestic refining capacity, and its current valuation of 48x TTM sales, against a $12.6 billion market cap, implies substantial execution risk and high expectations not fully supported by projected DoD revenues.

Analysis

It's been an outstanding year to own MP Materials (MP 0.56%) stock. From the end of 2024 through Oct. 3, 2025, Shares of the rare earth metals and magnets producer rose 358%. The U.S. Government's push to reshore manufacturing is the tailwind pushing this stock forward. Magnets made from rare earth elements, especially neodymium, are essential components in electronic vehicles, military drones, and everyday consumer electronics. The first thing to know about rare earth magnets is that China is the world's leading supplier of refined rare earth metals. This April, China halted exports of rare earth metals to the U.S. to strengthen its position when negotiating new tariffs. That decision has plenty of American businesses eager to build a more secure supply chain. In the right place at the right time As the only operational rare earth mine operator in the U.S., MP Materials is an obvious beneficiary of a reshoring push. Recently, USA Rare Earth has collected a great deal of capital with the intention of creating an end-to-end magnet production chain. The potential competitor acquired some mining rights in Texas, but it hasn't begun extracting any minerals yet. As the only magnet manufacturer with an operational mine, MP Materials is in a good position to receive government assistance. In July, the company entered a partnership with the U.S. Department of Defense (DoD) to build up the country's rare earth magnet supply chain. MP Materials intends to use government funds to construct a second domestic magnet manufacturing facility to be called the 10x Facility. Once complete, DoD has agreed to ensure the sale of every magnet the new facility produces for 10 years. The company thinks it can produce 10,000 kilograms annually with help from the new facility, once it's built. Also in July, MP Materials announced an agreement to sell magnets to Apple for use in its popular devices. Magnet shipments to the iPhone manufacturer are expected to begin in 2027. Missing the most important part of the supply chain Before getting too excited about MP Materials, it's important to understand that its facilities for refining ore into metal that can be used to manufacture magnets are small. This is why the deal with Apple involves recycling old magnets, not producing new ones from ore the company dug up in its Californian mining operation. The 10x Facility to be built in partnership with DoD is for manufacturing magnets. It isn't the big refinery that the company needs to actually remove China from its supply chain. The company only expects to improve the minor refining operation at its Mountain Pass, California facility. It's unlikely that MP Materials' planned improvements will allow for much independence from Chinese imports. Rare earth metal refining is a chemically intensive process that produces heaps of health-threatening pollution. It's hard to imagine environmental regulators in California letting such a refinery operate at scale. NYSE: MP Key Data Points Why MP Materials' stock is risky Investors who buy MP Materials at recent prices need the company to overcome some extremely high expectations, or they could suffer heavy losses. Most basic materials companies trade at price-to-sales multiples in the low single digits. With a market cap north of $12.6 billion, this stock is trading at 48 times trailing 12-month sales. The DoD established a guaranteed minimum price of $110 per kilogram of neodymium and praseodymium (NdPr) to be processed at the 10x Facility. The company hasn't broken ground yet. Even if we can assume it will rapidly complete construction and begin selling 10,000 kg annually to DoD at that price, we can only expect about $1.1 billion annually. A bet on MP Materials now is a bet that its new battery recycling program with Apple succeeds. New investors are also betting on perfect execution regarding its partnership with DoD. Those bets entail more risk than most investors should feel comfortable with. It's probably best to keep this company on a watchlist for now and revisit it after its 10x Facility is up and running. MP Materials (MP) has experienced a significant 358% stock appreciation, driven by its strategic position as the sole operational rare earth mine in the United States. This has been amplified by geopolitical tailwinds, including a U.S. government push to reshore critical supply chains and China's halt of rare earth exports. The company has secured high-profile agreements, notably a partnership with the Department of Defense (DoD) to construct a new magnet facility with a 10-year offtake guarantee, and a future supply deal with Apple for recycled magnets beginning in 2027. However, these positive developments are offset by substantial risks and operational gaps. A critical weakness is the company's lack of at-scale domestic refining capacity, which maintains its dependence on China for processing ore into magnet-ready metals and is underscored by the Apple deal's focus on recycling. Furthermore, the stock's valuation appears stretched, trading at 48 times trailing sales with a market capitalization exceeding $12.6 billion. This premium valuation suggests the market has priced in flawless and timely execution of its new facility and partnerships, leaving minimal room for potential setbacks or delays and creating significant downside risk for investors at current levels.

Key Decisions for Investors

• Given the stock's 48x price-to-sales multiple and extreme run-up, investors should exercise caution as the valuation appears to price in perfect execution of future projects, suggesting significant downside risk if delays or challenges arise.
• Monitor progress on the construction and commissioning of the '10x Facility', as its successful and timely completion is a critical catalyst that is already factored into the current stock price.
• Closely track any announcements or capital allocation towards developing at-scale domestic refining capabilities, as this remains the primary strategic bottleneck preventing the company from achieving full supply chain independence.
• Consider the stock a high-risk holding; it may be prudent for new investors to wait for tangible progress in de-risking operations, such as the new facility becoming operational, before initiating a position.
