5 terms

rare earth elements technical

"a leading producer of rare earth elements and vanadium, and is an emerging"

Rare earth elements are a set of 17 chemical metals used to make powerful magnets, batteries, catalysts and many tiny components inside electronics, renewable energy equipment and defense systems. They matter to investors because they are essential inputs for fast‑growing industries, and limited or concentrated supply can drive prices, create production bottlenecks or shift competitive advantage — like a factory running short of a specialized ingredient that halts output and affects profits.

uranium technical

"Today, Energy Fuels is the largest U.S. producer of uranium, a leading producer"

Uranium is a naturally occurring metallic element used primarily as the fuel for nuclear power plants, where a small amount produces large amounts of heat and electricity; think of it as a super-dense battery that powers reactors. It matters to investors because uranium supply, mining costs, and geopolitical or regulatory changes drive the prices of uranium and the profits of mining and utility companies, so shifts in availability or demand can meaningfully affect related stocks and energy markets.

vanadium technical

"a leading producer of rare earth elements and vanadium, and is an emerging"

Vanadium is a hard, silvery chemical element used to make metals and chemicals stronger and more durable, and as an ingredient in certain large-scale batteries for storing electricity. Investors care because vanadium’s price and availability affect the cost and profitability of steelmaking, manufacturing and energy-storage projects; shifts in supply, mining activity or demand for grid batteries can change costs and the value of companies tied to those markets.

titanium technical

"emerging global leader in the production of titanium and zircon minerals, which"

Titanium is a strong, lightweight, silver-gray metal known for resisting rust and heat, often used where durability and low weight matter, like airplanes, medical implants, and high-performance components. For investors, titanium's role as a critical industrial material means its availability, extraction costs, and price swings can affect mining companies, manufacturers, and industries that rely on it much like gasoline prices influence transport-heavy businesses.

zircon technical

"production of titanium and zircon minerals, which together are essential to"

Zircon is a naturally occurring mineral made of zirconium and silica, often found as small, hard crystals in sand or rock. Investors care because zircon is a raw material for ceramics, refractory products and certain industrial uses, so its supply, demand and price can affect mining companies and commodity markets much like cocoa or copper do for their industries — think of zircon as a specialty building block for high‑heat and high‑precision products.

DENVER, April 15, 2026 /PRNewswire/ - Energy Fuels Inc. (NYSE: UUUU) (TSX: EFR), a leading U.S. producer of uranium, rare earths, and critical materials, announced that Ross R. Bhappu has been appointed the Company's Chief Executive Officer, effective April 15, 2026.

Mr. Bhappu has served as President of Energy Fuels since August 2025 and brings more than three decades of leadership across mining, critical minerals, finance, and international resource development. He has held senior executive and board roles in the global mining sector, with extensive experience in project development, operations, government engagement, and capital markets. As President, Mr. Bhappu has been closely involved in advancing Energy Fuels' strategic priorities and supporting the execution of the Company's long-term growth strategy.

Mr. Bhappu succeeds Mark S. Chalmers, who is retiring after more than eight years as CEO and a distinguished career spanning five decades in the uranium and critical materials industry. Both Mr. Bhappu and Mr. Chalmers have been working closely for the past several months in anticipation of the transition. Following his retirement, Mr. Chalmers has agreed to serve as an exclusive uranium and rare earth consultant to the Company for a two-year period, providing continuity and strategic support as Energy Fuels advances its growth initiatives.

As CEO, Mr. Chalmers led the transformation of Energy Fuels from a small U.S. uranium producer into a diversified critical materials company with global reach. Today, Energy Fuels is the largest U.S. producer of uranium, a leading producer of rare earth elements and vanadium, and is an emerging global leader in the production of titanium and zircon minerals, which together are essential to clean-energy technologies, advanced manufacturing, and U.S. national security. Under his leadership, Energy Fuels leveraged its unique assets, infrastructure, and technical expertise to establish a domestic platform for critical material production and processing.

"Ross is a proven leader with deep industry experience and a strong understanding of Energy Fuels' operations and strategic direction," said Bruce D. Hansen, Chair of the Board of Directors. "At the same time, the Board extends its sincere gratitude to Mark for his extraordinary leadership, vision, and decades of service. Mark was instrumental in positioning Energy Fuels as the leading U.S. uranium producer and in guiding the Company's disciplined expansion into both upstream and downstream rare earth production. The Board is confident that Ross will build on this strong foundation as Energy Fuels continues to execute its long-term strategy."

Mr. Bhappu commented, "I am honored to be appointed Chief Executive Officer of Energy Fuels and deeply appreciative of Mark's leadership and vision. Mark's work laid the groundwork for Energy Fuels' evolution into a diversified critical materials company and I look forward to leading the company as it pursues a substantial growth initiative including the permitting and construction of a number of new mines, the planned expansion of the White Mesa Mill and the addition of REE metal and alloy making through the planned acquisition of Australian Strategic Materials Limited.  Energy Fuels has a talented team and Board of Directors, and I look forward to executing our strategic plan together."

Mr. Chalmers remarked, "Serving as CEO and guiding Energy Fuels' development into the leading U.S. critical materials company has been an honor, particularly considering my humble beginnings as a uranium miner in Colorado in the 1970s. I am confident that Ross will continue to inspire and lead our company to even greater heights."
