USAR Stock Just Bought a Brazilian Rare Earth Mine — and Wall Street Is Paying Attention

Seeing a small-cap miner that is still based in Stillwater, Oklahoma, announce a $2.8 billion acquisition in Brazil seems out of the ordinary. That’s the kind of transaction that completely changes a company’s narrative in a single morning, and USAR stock experienced something similar this week. Shares ended the session at 22.85, up another 1.2%, after rising more than 10% at Monday’s opening and cooling by Tuesday’s close. The after-hours tape continued to rise, reaching 23.14. That kind of move warrants a second look for a company that was trading close to $8 a year ago.

The news that USA Rare Earth would purchase 100% of Serra Verde Group, a Brazilian rare-earth miner that owns the Pela Ema mine in Goiás, served as the impetus. Investors would typically be alarmed by the structure’s $300 million in cash and approximately 126.8 million newly issued shares, but in this instance, they weren’t. The market was less afraid of the math and more fond of the reasoning. One of the very few facilities outside of Asia that produces heavy rare earths on a large scale is Serra Verde. These elements include dysprosium, terbium, yttrium, and erbium—names that sound unfamiliar until you realize they’re used in everything from EV motors to guided missiles.

Here, the strategic context is important. In an effort to free Western supply chains from Chinese hegemony, Washington has been gradually tightening its hold on rare-earth policy. The United States has already provided Serra Verde with a $565 million financing package. The International Development Finance Corporation lets you know who is interested. The Pela Ema asset, described by CEO Barbara Humpton as “one-of-a-kind,” is the only manufacturer outside of Asia that can supply all four magnetic rare earths on a large scale. It reads like a pitch deck, but in this instance, it’s largely true.

The story’s rapid evolution is what makes it intriguing. A few months ago, USA Rare Earth was primarily recognized for its acquisition of Less Common Metals in the UK and its Texas deposit. It now has a vertical integration pitch that would have seemed ambitious for a company ten times its size. Canaccord maintained a buy while raising its price target from $29 to $32. Even before the Serra Verde news, Wedbush had already started coverage with an Outperform rating and a $29 target. EBITDA is expected to reach between $550 and $650 million by 2027, with a long-term goal of approximately $1.8 billion by 2030. For a company that recently recorded $1.64 million in quarterly revenue, those are ambitious figures.

That’s the tension that underlies everything. With a $5 billion market capitalization and a 90% year-to-date gain, USAR is priced as though the transition has already begun, but the operational reality is still early. This quarter, the company started commissioning its first production line for rare-earth magnets. Only in 2024 did Serra Verde begin production. Here, there is both execution risk and belief, and it’s still unclear which will take center stage by the end of 2026.

As this develops, it’s difficult to ignore how rapidly rare earths have transformed from a minor geopolitical footnote to a major trade. The category’s original name was MP Materials. These days, USAR is striving to be something different—global, integrated, and strategically in line with US policy. The market keeps returning to the question of whether the Serra Verde deal actually closes cleanly in Q3 and whether USAR can scale production quickly enough to support the valuation. Traders are currently leaning in. The remainder is added later.
