CASPER, WY / ACCESS Newswire / May 8, 2026 / Ur-Energy Inc. (NYSE American:URG)(TSX:URE) (the "Company," "Ur-Energy" or "we"), a domestic uranium producer with ISR projects that are among the largest and lowest-cost in the United States, is pleased to announce its financial and operational results for the first quarter ended March 31, 2026. The Company will host a conference call and webcast on Monday, May 11. Details are provided below.

First Quarter 2026 Financial and Operating Results

Lost Creek Operations:

• Pounds Captured: We captured 110,314 pounds of U₃O₈, a 41% increase over Q4 2025 and a 48% increase over Q1 2025, reflecting improved flow rates following plant modifications and repairs.

• Production: We dried and packaged 95,599 pounds and shipped 103,956 pounds of U₃O₈.

• Inventory: We ended the quarter with 417,231 pounds of finished inventory at the conversion facility. This represents a 14% increase over Q4 2025 and a 13% increase over Q1 2025.

Financial Performance

• Contracted Sales: We sold 55,000 produced pounds of U₃O₈ as anticipated, generating $3.9 million in revenue, with a majority of our 2026 deliveries scheduled for the latter part of the year to complement the ramp-up and start-up schedules of Lost Creek and Shirley Basin.

• Increased U₃O₈ Sales Price: The average price per pound sold during Q1 2026 of $70.98 was $7.78 higher than Q4 2025, driven by deliveries under contracts negotiated in 2024 that contain a more favorable mix of base-escalated and market-based pricing.

• Lower Production Costs: The cash cost per pound of U₃O₈ sold was $37.51 in Q1 2026, a decrease of approximately 13% compared to Q4 2025.

Looking Ahead: Production Expansion and Advancing Exploration

• Lost Creek Operations: We drummed 57,479 pounds in April 2026, our highest monthly total since our 2023 ramp up decision. With a sand filtration system expected to come online this quarter and other optimization initiatives underway, we are positioned for improved flow rates and continued momentum.

• Shirley Basin Operations & Ramp-Up: We commenced operations at our second ISR mining facility in April 2026, reviving a historic uranium district. First shipments of uranium-loaded resin to Lost Creek are expected this summer, subject to final regulatory approval.

• Great Divide Basin Exploration: We continue to advance exploration projects toward production decisions. We have identified 13 ore grade intercepts at North Hadsell; recently commenced aquifer testing at Lost Soldier; and plan to commence an approximately 120-hole program at LC South this summer with the potential to extend Lost Creek mine units.

• Liquidity: Unrestricted cash and cash equivalents totaled $122.8 million at March 31, 2026. Our unrestricted cash position was $107.5 million as of April 30, 2026.

   Percentages may not recalculate precisely due to rounding.

Ur-Energy President and CEO, Matthew Gili, commented: "While most of our contracted deliveries are scheduled for later in the year, our first quarter results reflect higher contract sales pricing and continued operational improvements at Lost Creek, where our primary focus is driving higher production and efficiency. We are actively optimizing flow rates, bringing new header houses online, and enhancing plant performance to deliver sustained improvements. The start of operations at Shirley Basin, our second ISR mining facility, marks a major milestone for Ur-Energy and greatly expands our potential U.S. uranium production capacity. We look forward to commencing uranium-loaded resin shipments to Lost Creek this summer as we continue to execute on our growth strategy."

Lost Creek Operations

In Q1 2026, we sold 55,000 pounds of U₃O₈ at an average price of $70.98 per pound, generating $3.9 million in revenue. We dried and packaged 95,599 pounds of U₃O₈, an increase of 15% over Q1 2025, and shipped 103,956 pounds, compared to 138,337 pounds in Q4 2025 and 106,301 pounds in Q1 2025. Finished inventory at the conversion facility increased to 417,231 pounds at quarter-end, up 14% from Q4 2025 and 13% from Q1 2025.

Lower drummed and shipped volumes reflect reduced flow rates in late 2025 to allow the plant to make processing modifications and perform additional repairs, which limited pounds available for processing in the quarter. In Q1 2026, pounds captured totaled 110,314, up 41% from Q4 2025, as flow rates improved. These modifications, largely completed in Q4 2025, enhance processing efficiency and are expected to support higher annual production.

During the quarter, 15 header houses ("HHs") were in operation, with 13 in MU2 and two brought online in MU1 Phase 2. Development at MU1 Phase 2 remains on schedule, with all planned wells drilled and cased and seven of 10 planned HHs constructed. We continued delineation and development in MU4 and MU5 and initiated wellfield pattern planning for MU5. At quarter-end, 15 drill rigs were actively supporting our Lost Creek drilling program.

Optimization efforts are underway to improve flow rates affected by fine particles from the host formation, including the installation of a sand filtration system, which is expected to be online in Q2 2026. We are also actively developing a water treatment facility to further address fine particles and reduce wastewater.

We remain focused on increasing uranium production through the transition to MU1 Phase 2, bringing additional HHs online, optimizing wellfield chemistry, and enhancing maintenance and plant systems.

Shirley Basin: Operations Commenced in April 2026

By the end of Q1 2026, we had significantly advanced wellfield development and plant construction at Shirley Basin, our second ISR mining facility, a satellite operation integrated with Lost Creek, where uranium captured on resin will be transported to Lost Creek for final processing, drying, and drumming. The project is designed with three shallow mine units and is expected to enhance operational flexibility and scale.

During Q1 2026, in our first mine unit ("MU1"), HH 1-1 was connected to the plant, and installation of HH 1-2 progressed, with the main pipeline completed for the first four header houses. Wellfield development continued across HH 1-3 through HH 1-8. As of March 31, 2026, 540 wells had been pilot drilled, 312 of those wells had been cased, and eight drill rigs were active. Five HHs have been constructed, with additional units underway.

Construction progressed during the quarter across all major workstreams, with key infrastructure substantially complete, including roads, power, support facilities, evaporation ponds, and the plant structure. Ion exchange columns and most tanks have been installed, with ongoing work focused on piping, electrical systems, and interior plant construction.

Following completion of pre-operational inspections by the Wyoming Department of Environmental Quality, HH 1-1 was brought online in April 2026, marking the start of initial operations, with uranium-bearing solution now flowing through the plant and uranium being captured on resin. Uranium concentrations are expected to increase as the wellfield is further conditioned and additional circuits come online.

Subject to final regulatory approval, we expect to transport uranium-loaded resin to Lost Creek this summer. This milestone will represent the transition of Shirley Basin to commercial operations, substantially increase our production capacity, and add a much-needed domestic uranium supply to support the expanding nuclear energy industry.

Construction will continue through 2026, with additional plant systems planned for 2027. The site is fully staffed, supported by a phased hiring and training program aligned with operational ramp-up.

First Quarter 2026 Great Divide Basin Exploration Activities

Exploration activities continued across our Great Divide Basin projects. At Lost Soldier, located 17 road miles from the Lost Creek plant, aquifer testing commenced in April 2026 on test wells installed in 2025. Baseline environmental studies are planned this year to support potential permitting. With approximately 4,000 historic drill holes and proximity to Lost Creek, Lost Soldier has strong potential as a satellite operation. A technical report is underway with completion expected by year-end 2026.

At North Hadsell, 33 framework drill holes totaling approximately 33,800 feet were completed prior to seasonal sage grouse restrictions in March 2026. Seven holes returned significant mineralization, including 13 intercepts exceeding 0.20 GT (Grade (%eU₃O₈) times Thickness (ft)), which closely resembles the mineralization at Lost Creek. Results indicate a stacked roll-front system with up to eight individual roll fronts at ISR-amenable depths of about 300 to 800 feet.

Reclamation work at North Hadsell is planned this summer ahead of future drilling, and an approximately 120-hole exploration drill program is expected to commence at LC South in summer 2026.
