“Heavy” Rare Earths Produced by Energy Fuels Qualified for Use by Largest Permanent

Magnet Manufacturer in Japan

With today’s announcement of terbium oxide qualification, Energy Fuels is one step closer

to commercially producing the full portfolio of “light” and “heavy” rare earth oxides for

permanent magnets.

DENVER – August 19, 2026 – Energy Fuels Inc. (NYSE American: UUUU) (TSX: EFR) (ASX:

EF2), a leading U.S. producer of rare earth elements (REE), uranium, and other critical

materials, today announced that its terbium (Tb) oxide has successfully passed all

qualifications for use by one of the world's largest manufacturers of rare earth permanent

magnets outside China.

The Japan-based manufacturer has informed Energy Fuels that the Tb oxide produced at its

White Mesa Mill in Utah meets their specifications and is approved for use in commercial

REPM production with no further qualification or validation required.

"This latest qualification of Energy Fuels’ heavy rare earth oxides marks another significant

milestone in establishing a secure, diversified supply chain for critical rare earth materials, "

said Ross Bhappu, President and CEO of Energy Fuels. "Successful qualification of our

terbium oxide by one of the largest Japanese rare earth permanent magnet manufacturers

represents one of the strongest endorsements of our product quality and industry leading

rare earth processing capabilities to supply the heavy rare earth materials needed for

automobiles, advanced electronics, robotics, aerospace, defense systems, and other

advanced technologies. "

Terbium is among the most valuable and strategically important rare earth elements,

serving as a critical input that improves the heat resistance and performance of high-

strength NdFeB permanent magnets used in a variety of advanced technologies. Reflecting

its extreme scarcity and limited production in the West, terbium oxide currently

commands a market price of approximately $5.5 million per tonne according Benchmark

Mineral Intelligence (CIF Europe),

Energy Fuels previously announced the qualification of its neodymium-praseodymium

(NdPr) and dysprosium (Dy) oxides for the manufacture of rare earth permanent magnets.

Upon closing of the pending acquisitions of Australian Strategic Materials (ASM) and

Vacuumschmelze (VAC), Energy Fuels expects to become the leading vertically integrated

“mine-to-rare earth permanent magnet” producer in the U.S. and Europe. The NdPr, Tb and

Dy oxides produced by the Company at the White Mesa Mill will be key components of the

Company’s supply chain.
