Ur-Energy Releases 2019 Q2 Results

Littleton, Colorado (PR Newswire – August 2, 2019) Ur-Energy Inc. (NYSE American:URG)(TSX:URE) (the “Company” or “Ur-Energy”) has filed the Company’s Form 10-Q for the quarter ended June 30, 2019, with the U.S. Securities and Exchange Commission at www.sec.gov/edgar.shtml and Canadian securities authorities on SEDAR at www.sedar.com.

Ur-Energy CEO, Jeff Klenda said, “I am pleased to note that we generated $3.9 million of cash from operating activities during the current quarter, in which we sold 265,000 pounds at an average price of $43.31 for $11.5 million of gross sales. We expect to sell a total of 302,500 pounds at an average price of $53 per pound for gross sales of $15.9 million in the second half of 2019.”

Inventory, production and sales figures for the Lost Creek Project are presented in the following tables:

Notes:

1. Wellfield cash costs include all wellfield operating costs. Wellfield construction and development costs, which include wellfield drilling, header houses, pipelines, power lines, roads, fences and disposal wells, are treated as development expenses and are not included in wellfield operating costs.

2. Non-cash costs include the amortization of the investment in the mineral property acquisition costs and the depreciation of plant equipment, and the depreciation of their related asset retirement obligation costs. The expenses are calculated on a straight-line basis, so the expenses are typically constant for each quarter. The cost per pound from these costs will therefore typically vary based on production levels only.

3. Plant cash costs include all plant operating costs and site overhead costs.

4. Distribution cash costs include all shipping costs and costs charged by the conversion facility for weighing, sampling, assaying and storing the U₃O₈ prior to sale.

Note: U₃O₈ cost of sales include all production costs (notes 1, 2, 3 and 4 in the previous Production and Production Cost table) adjusted for changes in inventory values and excludes NRV.

During the quarter we sold 265,000 pounds under term contracts at an average price per pound of $43.31 per pound, of which 165,000 pounds were from production and the balance was purchased.

For the quarter, our uranium cost of sales totaled $9.0 million which included $2.8 million of purchase costs and $6.2 million of production costs. In 2019 Q2, we purchased 100,000 pounds at an average price of $27.80 per pound. The average cost per pound sold from production was $37.85.

Excluding the NRV adjustment of $2.1 million, the gross profit from uranium sales for 2019 Q2 was $2.4 million, which represents a gross profit margin of approximately 21%.

Note: The cost of sales per the financial statements includes ad valorem and severance taxes related to the extraction of uranium, all costs of wellfield, plant and site operations including the related depreciation and amortization of capitalized assets, reclamation and mineral property costs, plus product distribution costs. These costs are also used to value inventory and the resulting inventoried cost per pound is compared to the estimated sales prices based on the contracts or spot sales anticipated for the distribution of the product. Any costs in excess of the calculated realizable value are charged to the cost of sales per the financial statements as adjustments reflecting the lower of cost or NRV. These adjustments are excluded from U₃O₈ cost of sales because they relate to the pounds of U₃O₈ in ending inventories and do not relate to the pounds of U₃O₈ sold during the period.

Continuing Guidance for 2019

In 2019, we expect to deliver 665,000 pounds related to term contracts at an average price of approximately $48 per pound. Through June 30, 2019, we have sold 362,500 pounds of U₃O₈ at an average price of $48.86 and in Q2 we sold 265,000 pounds at $43.31 for $11.5 million in gross sales. Our remaining 2019 contractual sales commitments, by quarter, are as follows: 122,500 pounds in Q3 at an expected average price of $42 per pound; and 180,000 pounds in Q4 at an expected average price of $60 per pound.

For 2019, we put in place purchase contracts for 500,000 pounds at an average cost of $26 per pound. By quarter, our remaining 2019 purchase contract commitments are as follows: 122,500 pounds in Q3 at an expected average cost of $28 per pound; and 180,000 pounds in Q4 at an expected average cost of $24 per pound.

Gross profits from uranium sales are expected to be approximately $1.7 million in Q3 and $6.3 million in Q4, which represent gross profit margins of approximately 33% and 59%, respectively.

As at July 31, 2019, our unrestricted cash position was $6.1 million.

At the end of the second quarter of 2019, the average spot price of U₃O₈, as reported by UxC, LLC and TradeTech, LLC, declined to approximately $24.60 per pound because of low volumes and uncertainty over the Section 232 Trade Action. Subsequent to the end of the quarter and the announcement of the President’s decision regarding the Trade Action on July 12, the average spot price improved only slightly to $25.38 at the end of July.

Clearly, market fundamentals have not changed sufficiently to warrant further development of MU2. As a result, we do not anticipate any additional development for the remainder of this year, and we have reduced our production guidance to between 50,000 and 75,000 pounds at Lost Creek.

In response to the persistently weak uranium market, which continued as we awaited the outcome of the Section 232 Trade Action, we took aggressive measures in 2017 and 2018 to control costs. In response to the President’s decision regarding the Section 232 Trade Action, we will once again take aggressive cost cutting measures in 2019.

In 2017, we deliberately slowed development activities at MU2, reduced costs, focused on enhancing production efficiencies from our operating MU1 header houses and complemented our production with cost-effective purchases of uranium. In 2018, we implemented further cost reductions, purchased 100% of the uranium necessary to meet our 2018 contractual commitments, and increased our ending inventory position.

In the first half of 2019, we suspended further MU2 development activities, secured purchase contracts for 500,000 pounds of uranium at favorable prices, and sold 165,000 pounds related to 2020 obligations under existing term agreements.

The President’s July 12, 2019 Memorandum established a Working Group to develop recommendations for reviving and expanding domestic uranium production. The Working Group must report its recommendations back to the President within 90 days (October 10, 2019). There can be no certainty of the outcome of the Working Group’s findings and recommendations, if any, or the impact of actions taken in response to those findings and recommendations or the President’s Memorandum, and therefore the outcome of this continuing process and its effects on the U.S. uranium market is uncertain.

Ur-Energy CEO, Jeff Klenda, said further, “While our first half 2019 results remain solid, they are not sustainable in the current uranium market. We were disappointed in the President’s decision regarding the Section 232 Trade Action. I am completely perplexed by those who fail to recognize the inherent risk of allowing primary U.S. production to be unfairly reduced to less than 1% of U.S. demand by foreign practices seeking to restrict U.S. commerce. As a result, we once again find ourselves in the position where we must take aggressive cost control measures to ensure the future viability of the Company. Our intention is to maximize the amount of time, or “runway,” available to the Company while awaiting the results of the Working Group’s efforts. As always, avoidance of dilution to our shareholders remains among our highest priorities. At the same time, we will continue to pursue any and all remedies available to us, to remove such unfair practices in order to revive and expand domestic uranium production.”

In light of the President’s decision, Ur-Energy will now implement further cost reductions, including deep labor reductions, primarily at Lost Creek. We can no longer justify the added costs of maintaining full operational readiness as it relates to labor and have accordingly reduced staffing to the minimum levels necessary to maintain our facilities and meet regulatory compliance, while retaining core operational personnel who possess the critical knowledge necessary for the Company to ramp up when conditions warrant. This will enable the Company to maintain the Lost Creek facilities and preserve our ability to react to changing market conditions, while at the same time minimizing our need for additional funding during this protracted period of uncertainty.
