Energy Fuels Announces Q3-2025 Results

Increased uranium sales; continued strong low-cost uranium m ining poised to exceed production

guidance; successful “heavy” rare earth pilot production including 29 kilograms of Dy oxide through

September 30, 2025 and upcoming production of Tb oxide; post quarter completion of upsized $700

million 0.75% convertible senior notes boosts working capital to near $1 billion along with capped call

transactions that boost effective conversion price to $30.70 per share.

DENVER, November 3, 2025 - Energy Fuels Inc. (NYSE American: UUUU; TSX: EFR) (“Energy Fuels” or the

“Company”), a leading U.S. producer of uranium, rare earth elements (“REEs”), and other critical minerals,

today reported its financial results for the quarter ended September 30, 2025. The Company previously

announced details for its upcoming November 4, 2025, earnings call.

"The entire team continued to deliver on promises this quarter , including increased sales, increased

revenues and continued low-cost uranium production, which is resulting in significant cash margins as we

average down our cost of goods sold over time, and set the stage for increased gross margins in 2026,”

said Mark Chalmers, Energy Fuels’ Chief Executive Officer.

“We believe the performance of our uranium segment is well-timed, as we see several factors indicating

that demand for our domestically produced uranium is increasing. At the same time, we continue to make

remarkable progress in our rare earth segment, including ‘heavy’ rare earth pilot production at our White

Mesa Mill and qualification of our NdPr production for use by major automobile manufacturers. We also

received final government approvals for the development of our Donald Project rare earth and critical

mineral joint venture in Australia, along with receipt of a conditional Letter of Support from Export Finance

Australia for up to A$80 million in respect of senior debt project financing for the Project. To top it all off,

we completed an upsized offering of $700 million of convertible senior notes on very favorable terms ,

increasing our post-quarter working capital balance to nearly $1 billion.”

Q3-2025 Highlights

Unless noted otherwise, all dollar amounts are in U.S. dollars.

Financial Highlights:

• Robust Balance Sheet with Nearly $300 million of Liquidity: As of September 30, 2025 , the

Company had $298.5 million of working capital including $94.0 million of cash and cash

equivalents, $141.3 million of marketable securities (interest -bearing securities and uranium

equities), $12.1 million of trade and other receivables, $74.4 million of inventory, and no debt,

which puts the Company in a strong position as it advances its projects.

• Completion of Upsized $700 Million Convertible Senior Notes Offering Post-Quarter: On October

3, 2025, the Company closed its upsized offering of 0.75% Convertible Senior Notes due 2031 for

an aggregate principal amount of $700.0 million, including the exercise in full by the initial

purchasers of their option to purchase an additional $100.0 million of notes, on a deal led by

Goldman Sachs & Co. LLC . The notes have a conversion price of $20.34 per common share of

Energy Fuels ("Common Share"), which represents a premium of approximately 32.5% to the last

2

reported sale price of the Common Shares on the NYSE American on September 30, 2025, subject

to customary anti-dilution adjustments. The effective conversion price of the notes was increased

to $30.70 (representing a premium of 100% over the last reported sale price of the Common

Shares on the NYSE American on September 30, 2025) through the purchase of capped call

transactions.

• Over $15 Million of Additional Liquidity from Market Value of Finished Inventory: At October 31,

2025 commodity prices, the Company’s product inventory has a market value of approximately

$45.3 million, while the balance sheet reflects product inventory carried at historical cost of $30.3

million.

• Reduced Net Loss of $16.7 Million Compared to Q2 2025: During Q3-2025, the Company incurred

a net loss of $16.7 million, or $0.07 per common share, which is an improvement compared to a

net loss of $21.8 million, or $0.10 per common share during Q2 -2025, while at the same time

advancing the Company’s development projects and prepping the Company’s White Mesa Mill

(the “Mill”) for a conventional uranium ore processing run that commenced in early October 2025.

• Well-Stocked to Capture Market Opportunities and to Meet Long-term Contract Obligations: As

of September 30, 2025 , the Company held a total of 2,125,000 pounds of U 3O8 in inventory,

including 485,000 pounds of finished U 3O8, 1,525,000 pounds of U 3O8 in ore and raw materials,

and 115,000 pounds of work -in-progress U 3O8. Inventory increased from last quarter due to

Pinyon Plain, La Sal and Pandora mine ore production , partially offset by sales . The Company

expects these uranium inventories to continue increasing as we continue to mine additional ore

from these mines and potentially purchase additional ore from third parties, offset by upcoming

contract uranium sales and pot ential spot sales. The Company continues to retain most of its

finished uranium product in inventory in anticipation of higher uranium prices. The Company also

held 905,000 pounds of finished vanadium (“V2O5”), 37,000 kilograms (“kg”) of finished separated

neodymium praseodymium (“NdPr”) oxide and 9,000 kg of finished high purity, partially separated

mixed "heavy" samarium-plus ("Sm+") rare earth carbonate (“RE Carbonate”) in inventory.

Uranium Milestones:

• Q3-2025 U3O8 Sales: The Company sold a total of 240,000 pounds of U3O8 for a weighted average

realized price of $72.38 per pound for total gross proceeds of $17.4 million and a gross margin of

26%. Spot uranium prices during the quarter were relatively weak, averaging approximately

$74.66 during Q3-2025. Therefore, the Company elected to make only one spot sale for 100,000

pounds of U3O8 during the quarter.

• Q3-2025 Uranium Mine Production: During Q3 -2025, the Company mined ore containing

approximately 465,000 pounds of uranium from its Pinyon Plain and La Sal mines for a total of

approximately 1,245,000 pounds of contained U 3O8 through September 30, 2025. Ore mined at

the Pinyon Plain mine during Q3-2025 had an average grade of 1.27% U3O8, which the Company

believes is one of the highest -grade uranium mines in U.S. history. Overall grades for mined ore

have averaged 1.67% for the life of the mine so far , which is almost three times the estimated

average grade of proven and probable reserves for the mine of 0.58% U3O8 as set out in the

Company’s pre-feasibility study filed under National Instrument 43-101 ("NI 43-101") and Subpart

1300 of Regulation S-K ("S-K 1300"). Ore from the mine is being stockpiled at the Mill for a large-

scale ore processing run that commenced in early October 2025.

• Expected 2025 Uranium Product Production: The Company continues to mine and stockpile ore

from its Pinyon Plain, La Sal and Pandora mines, which is expected to total approximately 875,000

to 1,435,000 pounds of U3O8 contained in approximately 55,000 to 80,000 tons of ore from these

mines during 2025. With a total of approximately 1, 245,000 pounds of contained U 3O8 mined

through September 30, 2025 , and the addition of ore expected to be mined in Q4-2025, the

Company is in a strong position to meet or exceed the high end of this guidance. The Company

also expects to continue to seek to purchase uranium ore from third-party miners in the region,

and there is the potential to receive additional alternate feed materials and mine cleanup

materials, expected to add a total of approximately 160,000 to 200,000 pounds of additional

contained uranium to ore inventories, all of which will be processed as market conditions, Mill

schedules, and contract requirements may warrant.

• Expected FY-2025 Finished Uranium Production: The Company currently expects to process up to

approximately 670,000 pounds of U 3O8 in Q4-2025 from stockpiled ore mined from its Pinyon

Plain, La Sal and Pandora mines. This ore processing run is expected to continue through at least

Q1-2026. Expected Q4-2025 production, combined with the Company's 330,000 pounds of

production through Q3-2025, is expected to result in the production of up to approximately

1,000,000 pounds of U 3O8 for 2025. This is expected to be within the previously reported 2025

production guidance of 700,000 to 1 million pounds of finished U3O8.

• Uranium Sales During the Remainder of 2025: The Company expects to sell 160,000 pounds of

U3O8 in Q4-2025 under its existing long -term contracts with utilities. The Company may sell

additional uranium on the spot market during the remainder of 2025, depending on market

conditions.

• 2026 Preliminary Guidance: In 2026, the Company expects to sell between 620,000 and 880,000

pounds of U 3O8 under its current portfolio of long -term uranium sales contracts. The Company

may elect to sell additional uranium on the spot market or under new long -term contracts,

depending on Mill schedules and market conditions. The Company expects to produce between

430,000 and 730,000 pounds of U 3O8 during Q1-2026. Uranium and/or REE production for Q2 -

2026 and beyond is undetermined at this time, and will be based upon Mill schedules, market

conditions, and/or commercial or government demand for REEs.

• Expected Year End U3O8 Inventory: As a result of these sales, plus planned 2025 mine production,

at the end of 2025, the Company expects to hold a total of 1,985,000 to 2,585,000 pounds of U3O8

in ore inventories, including approximately 925,000 to 1,225,000 pounds of finished U 3O8

inventory, subject to any additional spot sales that may be made in 2025. This expected finished

goods uranium inventory is expected to be sufficient to satisfy the Company's 2025 and 2026

delivery requirements under existing contracts.

• Guidance: The Company's revised guidance for 2025 is as follows:

4

Current Guidance, as

Revised

Q2 2025

Low High

Mined (contained pounds of U3O8) 875,000 1,435,000

Alternate Feed Materials and other (contained pounds of U3O8)(1) 160,000 200,000

Processed (pounds of U3O8) 700,000 1,000,000

Sales (pounds of U3O8)(2) 350,000 350,000

Finished goods (pounds of U3O8) 925,000 1,225,000

Total inventories (contained pounds of U3O8)(2) 1,985,000 2,585,000

(1) "Other" includes ore purchases from 3rd party miners and potential cleanup from historic abandoned uranium mine s.

(2) Does not include any sales of inventory into the spot market, which the Company may make depending on market conditions. The Company expects to exceed

the high end of the range following its 100,000 pound spot sale in Q3-2025 that was not incorporated into this range.

• Uranium Costs Expected to Decline in Q4-2025 and FY-2026: The Company commenced

processing low-cost Pinyon Plain mine ores in Q4-2025 which is expected to continue through at

least Q1-2026, during which we expect to produce 1.1 to 1.4 million pounds of finished U 3O8.

During that Mill run, the average mining and transportation costs to the Mill for Pinyon Plain ore

are expected to be $10 to $14 per pound of recovered U 3O8 which together with an expected

milling cost of approximately $13 to $16 per pound of U 3O8, are expected to result in a total

weighted average cost of goods sold of approximately $23 to $30 per pound of U 3O8 recovered

(assuming royalty costs based on current market prices), ranking among the lowest costs for mined

uranium production in the world. These high -grade Pinyon Plain ores will be blended and

processed with the lower grade, higher cost, La Sal/Pandora ores through early 2026, after which

the Company can choose to pr ocess Pinyon Plain ores alone to maximize absolute margin, or in

conjunction with the La Sal/Pandora ore, purchased ores, and alternate feed materials to

maximize pounds of U3O8 produced, at the Company's discretion.

• Low Uranium Production Costs Expected for 2025: These low expected costs of mining are

expected to result in significant cash margins immediately upon the sale of mined uranium

product, and increasing gross margins as we average down our cost of goods sold over time. The

Company's inventories of finished U 3O8 had a weighted average cost of approximately $53 per

pound U 3O8 as of September 30, 2025, reflecting the weighted average cost of production and

purchase of finished inventories from various sources over the years, as the Company continues

to ramp up production and maximize economies of scale. These costs do not yet reflect the

expected lower costs of recently mined ores from the Pinyon Plain mine, which only recently

began to be processed. As the Company accounts for cost of goods sold as the weighted average

cost of its finished product inventories, sales of uranium produced in 2025 and into 2026 will

reflect the blended average of the existing 485,000 pounds of U3O8 finished inventories, plus the

cost of additional finished U3O8 produced from blended stockpiled Pinyon Plain and La Sal/Pandora

ores. This is expected to result in costs of goods sold of approximately $50 to $55 per pound for

U3O8 sales through the end of 2025, which is expected to drop to the $30 to $40 per pound range

in Q1-2026, depending on the quantity of any additional spot sales of inventory that may be made

in Q4-2025. The Company's ability to blend and match various sources of uranium feeds to satisfy

5

contract delivery requirements is a unique element of the Company's production capabilities that

no other producer has in North America.

• Increasing Gross Margins on Uranium Production: The Company expects to earn significant cash

margins immediately as uranium from its Pinyon Plain mine is sold. In addition, based on expected

decreasing cost of goods sold , the current portfolio of long -term contracts, and conservative

uranium price forecasts, gross margins from the Company’s uranium sales are expected to

increase over time through the end of 2026.

• Nichols Ranch and Whirlwind Update: The Company continues to observe positive results from

ongoing drilling at its Nichols Ranch in-situ recovery (“ISR”) Project in Wyoming. Both the Nichols

Ranch Project and Whirlwind Mine in Colorado are being prepared for production, as market

conditions warrant. If a positive production decision is made, production from these mines, when

combined with production from the Company’s Pinyon Plain, La Sal and Pandora mines, alternate

feed materials, uranium from monazite, and third -party uranium ore purchases, would be

expected to increase the Company’s production run-rate to approximately 2.5 million pounds per

year by as early as 2026.

• Roca Honda, Bullfrog, and Sheep Mountain Update: The Company continued advancing

permitting and other pre -development activities on its large -scale Roca Honda and Bullfrog

uranium projects during Q3 -2025, which together with its Sheep Mountain Project, have the

potential to expand the Company's uranium production to a run-rate of up to five million pounds

of U3O8 per year in the coming years. Roca Honda is currently on a Fast-41 transparency project

timeline.

• Uranium Market Update: As of October 31, 2025, the spot price of U 3O8 was $82.50 per pound

and the long-term price of U3O8 was $86.00 per pound, according to data from TradeTech.

Rare Earth Element Milestones:

• Significant Improvements in REE Market: REE markets have improved significantly over the last

three months, with NdPr prices increasing by approximately 25% from $61.88 per kg on June 30,

2025 to $77.73 on September 30, 2025, according to Asian Metals. According to Benchmark, as of

September 30, 2025, European NdPr, dysprosium ("Dy") and terbium ("Tb") prices of $87.50 per

kg, $850 per kg and $3,600 per kg according to Benchmark exceed the published Chinese prices

of $77.73 per kg, $226 per kg and $990 per kg, respectively, by 13%, 276% and 264%, respectively.

• Pilot Scale Production of Heavy REEs Currently Underway: On August 21, 2025, the Company

announced it successfully completed production of 99.9% purity Dy oxide, which is well in excess

of the 99.5% commercial specification . W e believe Energy Fuels is the first U.S. company to

publicly report Dy production volumes and purities. To date, the Mill has produced 29 kilograms

of Dy oxide in its pilot circuit. Pilot production of Tb oxide is targeted for December 2025.

• Commercial Scale Production of Heavy REEs: Based on the success of its “heavy” REE pilot, t he

Company intends to construct and commission commercial-scale Dy, Tb and potentially samarium

(“Sm”) separation capacity at the Mill, which could be operational as soon as Q4-2026. Multiple

magnet manufacturers and OEMs have expressed strong interest in obtaining Dy samples, further

validating the Company’s strategy to establish a fully non -Chinese rare earth supply chain for

commercial and defense applications.

• Export Finance Australia Issues Conditional Letter of Support for the Donald Project: On October

21, 2025, Export Finance Australia (“EFA”) issued a non-binding, conditional Letter of Support to

6

Energy Fuels and Astron Limited for up to AUD$80 million of senior debt financing for the Donald

Project. The Donald Project, which is expected to require approximately AUD$520 million in total

funding with a targeted 50:50 debt-to-equity ratio structure, is planned to commence production

in the second half of 2027 and is expected to produce ~7,200 tonnes per annum of rare earth

oxide concentrate, including ~1,000 tonnes of NdPr oxide, ~92 tonnes of Dy oxide, and ~16 tonnes

of Tb oxide. The Company expects to purchase 100% of the rare earth concentrate under a life-of-

mine offtake agreement for processing at the Mill. This conditional support from EFA marks a

significant step toward advancing project financing and reinforces the strategic importance of the

Donald Project in strengthening the Australia–U.S. critical minerals supply chain.

• U.S. Mined and Processed Rare Earths Successfully Manufactured into Permanent Magnets for

Use in EVs and Hybrids: On September 9, 2025, the Company announced that the high-purity

NdPr oxide produced at its Mill was manufactured into commercial scale rare earth permanent

magnets by South Korea's largest manufacturer of drive unit motor cores, pursuant to a previously

announced MOU, and has passed all quality assurance and quality control (QA/QC) benchmarks

for use in EV drive unit motors sold to major automotive manufacturers. This included the

successful manufacture of Energy Fuels' NdPr oxide into NdPr metal, neodymium -iron-boron

(“NdFeB”) alloy sintered blocks (45H grade), and high-performance, high-temperature NdFeB rare

earth permanent magnets (“REPMs”).

• Energy Fuels and Vulcan Elements Join Forces to Advance U.S. Rare Earth Magnet Security: On

August 26, 2025, the Company and Vulcan Elements, a U.S. manufacturer of REPMs, announced

that the companies have signed a Memorandum of Understanding ( “MOU”) to collaborate on

creating a resilient domestic supply chain for REPMs independent of China. Under the

collaboration, Energy Fuels has agreed to supply initial quantities of high -purity "light" and

"heavy" separated rare earth oxides to Vulcan in Q4 of 2025. Upon receipt, Vulcan will validate

Energy Fuels' NdPr and Dy oxides for production of REPMs. After validating the oxides, Vulcan and

Energy Fuels intend to negotiate additional long -term supply agreements for both NdPr and Dy

oxides. NdPr and Dy are key raw materials required for the manufacture of REPMs. The NdPr and

Dy oxides that Energy Fuels will provide to Vulcan under the MOU for validation will be sourced

exclusively from U.S. mines.

• Technology Applicable to a Wide Range of Feedstocks: Unlike other companies who are

experimenting with “heavy” REE production via recycling, we believe Energy Fuels is the only U.S.

company producing separated “heavy” REE oxides from commercial REE ores. The REE separation

techniques being utilized by Energy Fuels can also be applied to a wide range of feedstocks,

including mixed REE concentrates and recycled materials.

• Planned Expansion of Commercial Throughput of REEs: The Company continues the process of

updating the Mill's AACE International ("AACE") Class 4 Pre-Feasibility Study (not a Pre-Feasibility

Study subject to or intended to be compliant with NI 43 -101 or S-K 1300), originally released in

Q2-2024 to increase throughput by 50,000 tonnes per annum (" tpa") of monazite, producing

approximately 5,000 tpa of NdPr, 150 to 225 tpa of Dy, and 50 to 75 tpa of Tb. The Mill PFS

referenced above can be viewed on the Company's website, www.energyfuels.com.

Heavy Mineral Sands:

• The Toliara Project: Since acquiring the Toliara Project in Madagascar (the “Toliara Project”) on

October 2, 2024 , the Company has been in discussions with the Government of Madagascar to

7

establish the necessary legal regime to support development of the Project, which will be required

before a positive FID can be made. These discussions have been focused on, among other things,

mechanisms for achieving legal and fiscal stability, select ta x and customs benefits, necessary

adjustments to foreign exchange rules, protections from expropriation and access to international

arbitration for dispute resolution. The Company has also been seeking clarification of existing

procedures for adding monazi te to the Project's mining permit, which currently allows for the

production of ilmenite, rutile, and zircon. Recent discussions with the Government have focused

on addressing these issues through an investment agreement to be approved by Parliament or

through revisions to existing Malagasy law applicable to large scale mining investments.

On October 17, 2025, a new President of Madagascar was sworn in by the Country's High

Constitutional Court following a period of social unrest and political instability that resulted in the

removal of the Country's prior President, and, on October 20, 2025 , a new Prime Minister was

appointed. Shortly thereafter, on October 28, 2025, a new cabinet was announced. At this time,

it is too early to determine whether and to what extent recent social and political developments

in Madagascar may impact the Toliara Project, whether positively or negatively, including with

respect to the Project's development prospects or timelines, the ability to achieve suitable fiscal

or other terms applicable to the Project or the ability to achieve a positive FID. These

developments have not had an impact on the financial results of the Company at this time . The

Company will continue to monitor events as they unfold and intends to further engage with the

Government when appropriate.

• The Donald Project: The Company continued to advance the Donald Project, a large monazite -

rich heavy mineral sands (“ HMS”) project in Australia, pursuant to its joint venture with Astron

Corporation Limited. Having received the final major regulatory approval required to construct

and operate the Donald Project, along with advancing commercial and financing avenues, the

Company expects that an FID could be made on the Donald Project as early as Q4-2025 or early

2026. The Donald Project is of particular interest as the monazite concentrate has exceptional

concentrations of the "heavy" rare earth elements, including Dy, Tb, and Sm.

• The Company also obtained its exploration permit and plans to restart its drilling program at the

Bahia Project in Q4 -2025 with the goal of getting enough information to declare an S -K 1300-

compliant initial assessment and NI 43-101-compliant technical report in 2026.

Medical Isotope Highlights:

• During Q3-2025, the Company continued to utilize its research and development ("R&D") license

for the potential recovery of R&D quantities of Ra-226 at the Mill. During the remainder of 2025

and in early 2026, Energy Fuels plans to complete its process development engineering and, upon

successful completion of such engineering, expects to set up the first stages of the pilot facility

and produce R&D quantities of Ra -226 for testing by end -users of the product. Upon successful

production of R&D quantities of Ra-226, Energy Fuels plans to develop capabilities at the Mill for

the commercial -scale production of Ra -226 in 2027 -2028, conditional on completion of

engineering design, securing sufficient offtake agreeme nts for final radium production, and

receipt of all required regulatory approvals and project financing. At the same time, parallel with

its Ra-226 process development activities, the Company has applied for a license to concentrate

8

R&D quantities of Ra -228 at the Mill and is currently performing engineering on its process

development and R&D pilot facility for Ra-228 production.

Director Retirements

• On October 15, 2025, longtime Director Robert W. Kirkwood stepped down from his position

with the Company. Mr. Kirkwood served on the Board for over eight years, during which time he

served in a number of capacities, including most recently as Chair of the Compensation

Committee. Mr. Kirkwood was a highly respected and valued contributor, notable for his

balanced and well-reasoned insights.

• On October 29, 2025, Director Ivy V. Estabrooke stepped down from her position with the

Company. Ms. Estabrooke served on the Board for nearly four years, including on various

committees. Ms. Estabrooke brought to the Company insightful perspectives on government

relations and strategy and was an engaged and active participant in a range of valuable

discussions.

The Company extends its sincerest thanks to Mr. Kirkwood and Ms. Estabrooke for their dedicated

service to the Company and wishes each of them well in their future endeavors.

Mr. Chalmers continued:
