Year-End 2025 Highlights

Lost Creek Ramp-up Continues

• Pounds of U3O8 drummed increased by 161,231 pounds, or 65%, during 2025 as compared to 2024, for a total of 410,440 pounds. We ended 2025 with a total of 406,089 pounds of U3O8 in inventory compared to 335,327 pounds at year-end 2024.

• Wellfield and plant operations at Lost Creek continued to improve in 2025, with pounds of U3O8 captured increasing by 105,147 pounds, or 40%, over 2024. We added four header houses in Mine Unit 2 in 2025 and increased average flow rates by 890 gallons per minute, or 69%. In 2026, we are continuing our focus on plant optimization and improving flow rates.

• The 2025 average price per produced pound of U3O8 sold was $63.20 and the average cash cost per produced pound sold was $42.89.

Shirley Basin - Significant Progress Towards Commissioning

• Shirley Basin wellfield development and plant construction advanced significantly, with all ion exchange columns installed. We have pilot drilled 469 wells in Mine Unit 1 through February 2026, supported by eight active drill rigs. The project is fully staffed.

• Pending approvals from the Wyoming Department of Environmental Quality ("WDEQ"), Header House 1-1 is ready to be brought online to commence initial injection in and recovery from the wellfield. Development of additional header houses is ongoing, positioning the project for production operations and phased production growth.

Workforce Expansion to Support Production Growth

The total number of our full-time employees grew to 157 at year-end 2025, up from 101 in 2024, representing a 55% year-over-year increase as the Company added talented team members to support Shirley Basin and our other projects. This growth strengthened our excellent operations, technical, and corporate teams, positioning the Company for commissioning activities, production growth, and additional exploration in 2026.

Financial Strength

• As of December 31, 2025, we had cash and cash equivalents of $123.9 million, an increase of approximately $47.8 million from the $76.1 million balance on December 31, 2024. Our cash position as of March 4, 2026, was $115.3 million.

• Our production increases from 2024 to 2025 led to lower cash and non-cash costs per pound of U3O8 sold (exclusive of taxes), higher U3O8 profit per pound sold, and higher U3O8 profit margin.

• In December 2025, the Company closed an offering of $120 million aggregate principal amount of its 4.75% Convertible Senior Notes due 2031 in a private placement, which included the exercise in full by the initial purchasers of their option to purchase an additional $20 million of notes.

• In February 2026, 24,684,999 warrants were exercised for 12,342,499 whole common shares of the Company at an exercise price of $1.50 per share for proceeds of $18.5 million. The proceeds will be received in March. Including warrants that were exercised in January 2026, proceeds from warrants exercised in 2026 total $28.7 million. All but an insignificant number of warrants were exercised before the warrants expired in February.

Growing Uranium Resource Base

• As detailed in the updated S-K 1300 Technical Report Summary for the Lost Creek Property (the "Lost Creek Report"), dated March 9, 2026, that was filed as an exhibit to our Form 10-K, ongoing delineation drilling has resulted in an increase in our estimated uranium mineral resources. See our separate press release on the Lost Creek Report issued today.

• Our combined estimated mineral resources for Lost Creek and Shirley Basin are 21.0 million pounds in the Measured and Indicated categories, and 10.4 million pounds in the Inferred category at December 31, 2025. The estimated mine life at Lost Creek through final wellfield production (but excluding additional restoration) has been extended by nearly three years, with the potential for additional cash flow and long-term growth. See our separate press release on the Lost Creek Report issued today.

Exploration Programs Continue to Advance

• Lost Soldier Project: Aquifer test wells were installed at our Lost Soldier Project in 2025, with hydrogeologic testing planned to begin in March 2026, to be followed by baseline environmental studies. Work on a technical report is also underway to establish a mineral resource estimate through detailed roll-front mapping. Located approximately 17 miles from Lost Creek, Lost Soldier offers possible satellite development and infrastructure synergies.

• North Hadsell Exploration: 32 of the planned 50 drill holes have been completed, returning significant mineralization, including 13 intercepts exceeding 0.20 grade-thickness ("GT"), which is the cut-off GT the Company uses at Lost Creek to evaluate economic mineral resources. Stacked roll-front horizons with grades and thicknesses comparable to Lost Creek indicate potential for ISR development at a meaningful scale.

• Potential Growth Near Lost Creek: Drilling is expected to shift from our North Hadsell Project to our LC South Project in summer 2026 with a planned 120-hole program, reinforcing long-term growth optionality in the Great Divide Basin.

Ur-Energy President and CEO Matt Gili commented: "2025 reflected strong execution across our operating and development portfolio. At Lost Creek, we delivered meaningful year-over-year improvements in production, throughput, and operating performance while continuing to expand our resources and extend mine life. At the same time, we advanced Shirley Basin toward commissioning, with significant construction complete, drilling well advanced, and a talented team in place. With two ISR platforms, a growing resource base at Lost Creek, and a robust exploration pipeline in the Great Divide Basin, we are well positioned to drive production growth and long-term value in 2026 and beyond."

Lost Creek ISR Project - Great Divide Basin, Wyoming

Focus on Operational Execution

During 2025, Ur-Energy advanced wellfield development and brought four additional header houses online at Lost Creek. The Company drummed 410,440 pounds of U3O8 in 2025, up from 249,209 pounds in 2024,and shipped 420,144 pounds, reflecting improved throughput and operating execution.

The Company continues to make progress proactively identifying and addressing operational challenges while advancing detailed engineering solutions to improve flow and plant performance.

In 2026, operational priorities remain focused on continued ramp-up, plant optimization, and sustained production rate increases. Several new header houses are expected to be brought online in MU1 Phase 2 during the first half of the year, with the first commissioned in February. Planned investments, including commencement of construction of a wastewater treatment facility, are expected to facilitate increased overall plant throughput over time.

Lost Creek is fully staffed, with ongoing emphasis on retention and training to support continued operational improvement and efficiency. With 15 active drill rigs, drilling and wellfield development remain on schedule, positioning the operation to continue increasing production.

Drilling at Lost Creek continues to demonstrate consistent success in expanding estimated mineral resources and extending mine life. As detailed in the Lost Creek Report, the mineral resource estimates for the Property reflect 11.9 million pounds in the Measured and Indicated categories, and 10.4 million pounds in the Inferred category. The estimated mine life through final wellfield production (but excluding additional restoration) has been extended by nearly three years, with the potential for additional cash flow and long-term growth. Historically, each phase of drilling has supported the addition of estimated mineral resources. Notably, only a relatively small portion of the Lost Creek Property has been drilled to date, underscoring the scale and growth potential of the asset base and supporting a potential longer-term production outlook.

Shirley Basin ISR Project, Shirley Basin, Wyoming

Significant Progress Towards Commissioning

During 2025, we made significant progress on wellfield development and initiated construction of the plant facility at Shirley Basin. Construction of the plant building is well advanced, with all ion exchange columns installed and key tanks set. Remaining interior construction, commissioning of production circuits, and construction of phase two infrastructure are expected to progress through 2026, followed by the ramp-up of operations.

Pending approvals from the WDEQ, Header House 1-1 is ready to be brought online to commence injection in and recovery from the wellfield. Development of additional header houses in Mine Unit 1 is ongoing, positioning the project for production operations and phased production growth as commissioning progresses.

The wellfield data package for Mine Unit 1 is currently under review by the WDEQ, which also began its pre-operational inspection in late February 2026. Additional site visits are expected as the inspection process continues. Following completion of the inspection and regulatory review, we expect approval to begin recovery from the wellfield and collection of uranium onto resin in the plant.

Drilling activity continues at a strong pace. Through February 2026, the Company has pilot drilled 469 injection and production wells in Mine Unit 1, currently supported by eight active drill rigs. With delineation drilling completed historically, activity is focused on efficient development and construction to support near-term production.

Shirley Basin has a licensed wellfield capacity of one million pounds of U3O8 per year. Total annual production from wellfield recovery and toll processing is permitted at up to two million pounds U3O8 equivalent. Shirley Basin is designed as a satellite operation, with loaded resin to be transported to Lost Creek for processing. We expect to be able to commence transporting loaded resin to Lost Creek for processing, drying, and drumming in summer 2026, subject to the receipt of additional regulatory approvals.

Staffing at Shirley Basin is substantially complete, with a focus on training and operational readiness. Leveraging Ur-Energy's operating experience at Lost Creek, the Company expects a disciplined ramp-up as Shirley Basin transitions into production, providing a second U.S. ISR production platform and meaningful growth in overall uranium output.

Expanded Exploration Programs to Advance the Development Pipeline

Lost Soldier Project

In 2025, the Company renewed exploration in Wyoming's Great Divide Basin, advancing the Lost Soldier Project with the installation of aquifer test wells to support ISR evaluation. Aquifer testing is scheduled to begin in March 2026, followed by baseline environmental studies to support potential permitting. Located approximately 17 miles from the Lost Creek plant, Lost Soldier offers possible satellite development optionality by leveraging existing infrastructure. Work is also underway on a technical report for the project.

North Hadsell and LC South Exploration

Drilling at the North Hadsell Project in the Great Divide Basin continues to deliver encouraging early results from the ongoing 50-hole program. Through February 2026, we have drilled 32 wide-spaced holes at North Hadsell totaling 32,965 feet, including seven holes intersecting significant uranium mineralization with 13 intercepts exceeding 0.20 GT. These grades and thicknesses closely resemble the mineralization at Lost Creek, where the Company applies a 0.20 GT cut-off in evaluating economic mineral resources.

Results also suggest the presence of multiple stacked roll-front horizons comparable to those at the Company's producing Lost Creek ISR mine, supporting ISR recovery potential. Two of the most compelling holes, located approximately 1.5 miles apart at similar depths, indicate meaningful potential scale to the mineralized system and reinforce North Hadsell's potential as a future development opportunity.

Drilling is expected to transition from North Hadsell to the LC South Project in summer 2026, where a larger 120-hole program is planned, reinforcing the Company's longer-term growth pipeline near Lost Creek.
