MP Materials vs. USA Rare Earth: Which Rare-Earth Stock Is a Better Buy in 2026?

As the global race for resource independence accelerates, the domestic rare earth supply chain has become a focal point for long-term investors. Choosing between MP Materials (NYSE:MP) and USA Rare Earth (NASDAQ:USAR) involves weighing established production against speculative future growth.

MP Materials focuses on scaling its existing mine in California while USA Rare Earth aims to build a new supply chain from scratch in Texas. Both companies seek to reduce global reliance on foreign sources for the essential minerals used in everything from electric vehicle motors to high-tech defense systems.

MP Materials produces critical minerals at its Mountain Pass facility and serves as a major player in the mining stocks landscape, precisely rare earths. It recently shifted away from selling concentrate to Chinese distributors and now serves clients like Apple (NASDAQ:AAPL) , General Motors (NYSE:GM) , and the U.S. Department of Defense (or the Department of War).

In FY 2025, revenue grew 35.1% to nearly $275.5 million. Despite this growth, the company reported a net loss of approximately $85.9 million and, therefore, a negative net margin.

As of its December 2025 balance sheet, the company maintained a current ratio of 7.2x, indicating its ability to cover short-term debt with current assets. Its debt-to-equity ratio of 0.4x compares total debt to shareholders’ equity, indicating a relatively low reliance on borrowed funds. Free cash flow (FCF), calculated as cash from operations minus capital spending, was nearly negative $328.1 million as the firm continues to develop and progress mines and production.

USA Rare Earth is developing a full domestic supply chain from its Round Top project in Texas. The company aims to provide metals and magnets directly to industrial customers.

In FY 2025, revenue reached nearly $1.6 million as the company moved toward its initial operations. However, it recorded a net loss of close to $297.6 million,  reflecting the massive costs associated with building out a mine-to-magnet value chain before commercial production begins.

As of its December 2025 balance sheet, the company reported a debt-to-equity ratio of 0.0x, showing it has no total debt relative to its equity. Its current ratio of 10.2x suggests a strong ability to cover immediate liabilities with existing assets. FCF was negative $86.3 million, representing cash from operations minus capital expenditures.
