Energy Fuels Announces Closing of Upsized US$700.0 Million Convertible Senior Notes Offering and Full Exercise of Initial Purchasers' Option to Purchase Additional Notes

DENVER, Oct. 3, 2025 /PRNewswire/ - Energy Fuels Inc. (UUUU)?("Energy Fuels" or the "Company") today announced the closing of its previously announced upsized offering of 0.75% Convertible Senior Notes due 2031 (the "Notes") for an aggregate principal amount of?US$700.0 million (the "offering"), including the exercise in full by the initial purchasers of their option to purchase an additional US$100.0 million of Notes.?

Goldman Sachs & Co. LLC acted as sole book-running manager for the offering. Cantor acted as a lead manager and capped call coordinator for the offering.? Morgan Stanley acted as a lead manager for the offering. BMO Capital Markets and Canaccord Genuity acted as co-managers for the offering.

Energy Fuels (UUUU)' CEO,?Mark Chalmers, commented?"We are pleased to announce the completion of a significant financing milestone, as we capitalized on the robust market environment. We believe the convertible notes, with an attractive annual coupon of 0.75%, compare favorably to traditional debt financing. In addition, we purchased capped call options, which offset dilution for conversions at maturity until our share price has potentially doubled from the reference price of $15.35 per share.

This strategic capital raise strengthens our balance sheet and enhances our ability to accelerate our rare earth initiatives, including the expansion at our White Mesa Mill and Donald Project in Australia. We are pleased to announce the closing of this offering, reflecting strong investor sentiment not only regarding our rare earth initiatives, but also our low-cost, US-leading uranium production, that enabled an additional $67.5 million upsizing. We believe this outcome represents a clear vote of confidence in our team and strategy."
