USA Rare Earth, the Oklahoma company racing to build a Western alternative to China’s grip on critical minerals, has agreed to buy Serra Verde, one of Brazil’s few producing rare-earth mines, in a $2.8 billion cash-and-stock deal that marks one of the most ambitious attempts yet to diversify supply chains for the materials that power everything from electric motors to fighter jets.
The transaction calls for $300 million in cash and another $126.9 million in newly issued USA Rare Earth shares. If regulators and other closing conditions cooperate, the deal is expected to close in the third quarter of 2026.
For a company still developing its own U.S. projects, the acquisition hands USA Rare Earth immediate access to an operating mine already churning out some of the most strategically sensitive rare earths on the planet.

Rare earths, seventeen obscure elements whose unique magnetic properties make them indispensable in high-tech applications, have quietly become one of the sharpest points of friction between Washington and Beijing. China mines roughly 70 percent of the world’s supply and refines nearly 90 percent, including material shipped in from elsewhere. That dominance has left Western governments increasingly uneasy as demand for these minerals explodes with the shift to electric vehicles, wind power, and advanced defense systems.
“The world has become too dependent on a single source and it’s high time to break that dependency,” USA Rare Earth CEO Barbara Humpton told CNBC’s “Squawk Box” on Monday.
The deal, she added, delivers “access to a producing mine that produces the four magnetic rare earths that are going to be serving our industry.”
Those four—neodymium, praseodymium, dysprosium, and terbium—are the superstars of the rare-earth world. They form the backbone of high-performance permanent magnets used in EV motors, offshore wind turbines, and precision-guided munitions. Serra Verde already has a 15-year offtake agreement with a special-purpose vehicle backed by U.S. government entities and private capital that locks in 100 percent of its production of those four elements. In an industry where long-term, reliable supply contracts are gold, that agreement is a powerful calling card.
Serra Verde Group CEO Thras Moraitis framed the deal as a strategic nexus.
“Rare earths represent a strategic nexus where national and energy security, and technological supremacy, converge,” he said.
He noted that the U.S. government has been “very active” in trying to spur upstream investment, including ideas such as floor prices to make Western production more viable.
“The Western rare earth sector stands at a critical inflection point,” Moraitis added, “as governments and strategic industries urgently seek reliable sources of critical rare earths—particularly scarce heavy rare earths.”
The purchase is more than just an asset grab for USA Rare Earth, as it short-circuits years of permitting and construction timelines in the United States and instantly gives the company a foothold in the global market. It also diversifies its risk away from purely domestic projects that have faced the usual environmental, regulatory, and community hurdles.
Markets offered a mixed verdict. USA Rare Earth shares slipped 3.4 percent in premarket trading, a reminder that dilution from the new stock issuance and the sheer size of the bet can give investors pause. Still, the stock is up about 68 percent year-to-date, reflecting broader enthusiasm for companies that position themselves as part of the West’s critical minerals push.
The deal arrives at a moment when the conversation around supply-chain security has moved from polite concern to urgent policy. Washington has spent years layering incentives through the Inflation Reduction Act, the Defense Production Act, and various loan guarantees to coax domestic and allied production online.
Buying an existing, producing mine in Brazil, rather than starting from scratch, accelerates that timeline in a way that greenfield projects rarely can.
However, building out full refining and magnet-manufacturing capacity outside China is still a heavy lift. Environmental standards in Brazil, while improving, come with their own scrutiny. And Beijing has shown before that it can weaponize its market dominance when it chooses. Still, the Serra Verde acquisition gives USA Rare Earth something it lacked yesterday: real, near-term production of the exact materials defense contractors and automakers are scrambling to secure.
In the end, this is less a simple mining transaction than a calculated geopolitical maneuver dressed up in corporate clothing. By writing a $2.8 billion check for a Brazilian asset tied to long-term U.S. offtake contracts, USA Rare Earth is betting that governments and industries will pay a premium for certainty.
