CASPER, WY / ACCESS Newswire / August 10, 2026 / Ur-Energy Inc. (NYSE American:URG)(TSX:URE) ("Ur-Energy" or the "Company"), America's largest and fastest-growing domestic ISR uranium producer, is pleased to announce its financial and operating results, along with development and exploration highlights, for the second quarter ended June 30, 2026.

Financial and Operating Highlights

• New Record for Pounds Drummed: Processed and packaged 140,873 pounds of U3O8 during the quarter, an increase of 47.4% over the first quarter of 2026 and 25.7% over the second quarter of 2025, and the most drummed in a calendar quarter since the start of ramp up at Lost Creek in 2022.

• Continued Increase of Pounds Shipped: Shipped 149,747 pounds of U3O8 to the conversion facility during the second quarter, an increase of 44.0% over the first quarter of 2026 and 42.2% over the second quarter of 2025.

• Delivered on Contracted Sales: Sales for the second quarter under contracted deliveries totaled 215,000 pounds of U3O8 as projected, generating $14.4 million in product sales revenue.

• Continued Low-Cost Production: The cash cost per pound of U3O8 sold during the quarter remained low at $40.20, compared to $37.51 for the first quarter of 2026 and $42.83 for the second quarter of 2025.

• Strong Liquidity: Unrestricted cash and cash equivalents totaled $95.3 million at June 30, 2026.

• Ending Inventory: Ended the second quarter with 348,292 pounds of finished inventory at the conversion facility, which was a 16.5% decrease from the first quarter of 2026 and 10.4% more than the second quarter of 2025.

Matt Gili, President & CEO of Ur-Energy, stated, "The second quarter of 2026 marked an inflection point for Ur-Energy. The continued ramp up at Lost Creek and the commencement of production at Shirley Basin has transformed us into both the largest and the fastest-growing ISR producer of uranium in the United States. We continue to expand our production, our operating costs remain among the lowest in the country, and our organic growth pipeline is advancing at pace."

Development and Exploration Highlights

• Final Regulatory Approval at Shirley Basin: In late June 2026, the Company received final state regulatory authorization to commence full production operations at Shirley Basin, including the transportation of uranium-loaded resin to Lost Creek for processing and shipping.

• Shirley Basin Ready to Commence Full Operations: All plant infrastructure and processes are in place at Shirley Basin to transport uranium-loaded resin to Lost Creek and launch full production operations only two and a half years after the build out decision. The first shipment is expected imminently.

• Production Optimization at Lost Creek: Continued to increase flow rates and further increase production, adding header houses, installing a sand filtration system and breaking ground on the planned wastewater treatment facility in July, and advancing initiatives to optimize wellfield chemistry.

• Rapid Progress on Near-Mine Exploration: Completed test well clusters and began baseline environmental studies at Lost Soldier in anticipation of potential permitting as a satellite mine feeding Lost Creek. Also commenced planning and preparations for a 120-hole exploration drilling program at Lost Creek South - a highly prospective, under explored approximately 16-square mile property immediately adjacent to the Lost Creek operation.

Summary of Selected Second Quarter Results

1. All sales were under long-term contracts.

2. Pounds in inventory at the conversion facility.

3. Includes ad valorem and severance taxes but excludes non-cash costs.

Lost Creek Production Growth and Continued Optimization

At Lost Creek, Ur-Energy's flagship uranium ISR mining project, the Company drummed 140,873 pounds of U3O8, an increase of 47.4% over the first quarter of 2026 and 25.7% over the second quarter of 2025. The Company also shipped 149,747 pounds during this time, an increase of 44.0% over the first quarter of 2026 and 42.2% over the second quarter of 2025.

Wellfield development and surface construction remain on schedule for the Company's 2026 operating plans. Subject to regulatory approval, the Company expects to commence wellfield construction and installation in the fifth mine unit by year-end 2026, where 15 header houses are planned from late 2026 through 2028. At quarter-end, 17 drill rigs were actively supporting the Lost Creek drilling program - an increase of two from the previous quarter.

A sand filtration system was installed at Lost Creek during the quarter and brought online in July to increase flow rates while the new wastewater treatment facility is completed. Development of the wastewater treatment facility accelerated during the quarter, and the Company broke ground in July 2026. Completion and operation are planned for the first quarter of 2027. Additionally, the Company expects to complete implementation of an enhanced maintenance program and improvements to the reverse osmosis system by year-end 2026.

Shirley Basin Ready for Full Production Operations

In April 2026, the Company commenced limited initial operations to extract and capture uranium at Shirley Basin. While the project is permitted as a second production and processing hub operation to maximize future optionality in the emerging Great Divide Basin uranium district, Shirley Basin is designed as a spoke of the Lost Creek hub to optimize capital efficiency.

While conducting only limited operations, the Company succeeded in capturing 10,634 pounds of U3O8 at the Shirley Basin plant during the second quarter of 2026. In late June 2026, the Company received final authorization from the State of Wyoming to commence full production operations, including the transportation of extracted and captured uranium to Lost Creek. By the end of July 2026, all plant infrastructure and processes for transportation were in place. As of the date of this release, the Company was preparing a trailer for the first shipment to Lost Creek to transition Shirley Basin to full production operations.

Various additional plant construction activities are expected to continue through 2026 as the Company continues to deliver on its optimization strategy.

Exploration Activities in the Great Divide Basin

Lost Creek South: Totaling approximately 16-square miles immediately adjacent to the Lost Creek operation, Lost Creek South has clear potential as a low-cost, near-mine expansion opportunity. During the second quarter, the Company carried out planning and preparation activities for a 120-hole exploration program that is expected to commence in the third quarter of 2026 with three drill rigs.

Lost Soldier: With approximately 4,000 historic drill holes and related data indicating mineralization, and close proximity to the Company's Lost Creek operation, Lost Soldier has superb potential as a satellite operation. During the second quarter of 2026, the Company completed pump testing of two of the three aquifer test well clusters and began work on baseline environmental studies in anticipation of possible permitting. Additionally, completion of a technical report including a resource estimate for the project is expected by year-end 2026.

North Hadsell: The Company drilled 33 holes totaling approximately 33,800 feet in the first quarter of 2026, with 13 holes hitting mineralization that closely resembles that of Lost Creek. During the second quarter, the Company advanced the opportunity by completing abandonment of the previously drilled holes.

Sales and Inventory

During the second quarter, the Company sold 215,000 pounds of U3O8 at an average price of $66.85 per pound, generating $14.4 million in product sales revenue. A total of 348,292 pounds of finished inventory was held at the conversion facility at quarter-end, compared to 417,231 pounds at the end of the first quarter of 2026 and 315,607 pounds at the end of the second quarter of 2025.

Including the 270,000 pounds delivered in the first half of 2026, the Company expects to make base deliveries of 1.0 million pounds of U3O8 in 2026. After the end of the quarter, the Company proactively entered into transactions to defer delivery of 150,000 pounds to 2027 and 150,000 pounds to 2029. The deferral transactions increase the Company's ability to make subsequent 2026 deliveries from existing inventory and new production. A larger number of expected 2026 deliveries were scheduled in the latter part of the year to coincide with the ramp-up and startup schedules for Lost Creek and Shirley Basin.
