Energy Fuels Inc. (UUUU) shares jumped Friday after the company announced a breakthrough that matters more than you might think: its high-purity dysprosium oxide just passed all the quality tests from a major South Korean automotive manufacturer. Why does this matter? Because dysprosium is one of those materials that makes modern technology actually work, and almost all of it comes from China.

The Material That Makes Magnets Matter

Dysprosium oxide is a key ingredient in neodymium-iron-boron (NdFeB) permanent magnets, which sounds technical until you realize these magnets are everywhere. They boost durability and magnetic strength in electric vehicles, hybrid cars, advanced robotics, and a whole range of commercial technologies. Without dysprosium, those magnets lose performance at high temperatures, which is a problem when you're trying to power a car or fly a drone.

Speaking of defense, dysprosium oxide shows up in missiles, jet engines, guidance systems, and even control rods in Naval reactors. It's not just a nice-to-have material.

Why This Milestone Matters

"Production of dysprosium oxide that meets stringent magnet specifications is yet another key milestone in the Company's critical materials strategy, demonstrating Energy Fuels' unique and rapidly expanding capabilities in the rare earth sector, and in particular our ability to produce high-purity separated 'heavy' rare earth oxides from monazite at our White Mesa Mill in Utah," said Mark Chalmers, CEO of Energy Fuels.

The qualification is especially significant because supplies of "heavy" rare earth oxides outside China are extremely limited. China imposed export controls on seven rare earth elements in April 2025, including dysprosium, terbium, and samarium. Those restrictions remain in place, making domestic production increasingly valuable.

Energy Fuels shares were up 8.87% at $15.22 at the time of publication on Friday.
