B. Riley Securities, Inc. and H.C. Wainwright &amp; Co., LLC acted as co-managers for the offering.Ur-Energy's CEO, Matt Gili, commented, &#34;We are very pleased with the market's enthusiastic reception to this offering, which was oversubscribed and attracted participation from several well-known institutional investors who are new to Ur-Energy. The strong demand validates the market's confidence in our team, strategy and outlook. The notes, with an attractive annual coupon of 4.75% and a conversion price of $1.73, representing a 27.5% premium to the December 10, 2025 share price on the NYSE American, provide flexible capital to support the continued optimization of operations at Lost Creek and the start-up of our second in-situ recovery (&#34;ISR&#34;) mine, Shirley Basin-the fifth producing ISR mine in the United States. The capped call transactions will further mitigate dilution until our share price has potentially doubled from the reference price of $1.36 per share, allowing us to fund growth while protecting shareholder value.&#34;Strategic Capital Raise<ul><li>The proceeds from this strategic capital raise are expected to strengthen our balance sheet and enhance our ability to complete the critical ramp-up of production at our Lost Creek mine and finalize construction activities at Shirley Basin.</li><li>Flexible, Non-Covenant Structure: The offering is structured without restrictive covenants as seen in conventional debt, offering the Company enhanced operational and financial flexibility versus typical secured debt instruments.</li><li>Conversion Optionality: While convertible into common shares, no par value, of Ur-Energy (the &#34;common shares&#34;) under certain conditions, the notes will initially accrue interest like debt and are not immediately dilutive, and conversion features are structured at a premium, aligning interests with long-term shareholder value.</li><li>Lower Dilution vs. Equity: Compared to a straight equity offering, this structure allows Ur-Energy to raise meaningful capital with less near-term dilution to existing shareholders, particularly with conversion pricing set at a premium level.</li><li>Proceeds to Drive Growth: Proceeds will support the broader expansion of the Company's exploration program and development pipeline.</li></ul>Summary of the Offering<ul><li>Cash interest coupon of 4.75% per annum, payable semi-annually in arrears on January 15th and July 15th of each year, beginning July 15, 2026.</li><li>Conversion price of approximately $1.73 per common share, which represents a conversion premium of approximately 27.5% to the last reported sale price of the common shares on the NYSE American LLC (the &#34;NYSE American&#34;) on December 10, 2025, subject to adjustments in some events but will not be adjusted for any accrued and unpaid interest.</li><li>The potential economic dilution upon conversions of the notes was mitigated through the purchase of cash-settled capped call options with a cap price of $2.72 (representing a premium of 100% over the last reported sale price of the common shares on the NYSE American on December 10, 2025). The purchase price for the capped call options was approximately $16.6 million.</li><li>Conversions of the notes may be settled in common shares, cash or a combination of common shares and cash at Ur-Energy's election. Additionally, Ur-Energy will have the right to redeem the notes in certain circumstances and will be required to offer to repurchase the notes upon the occurrence of certain events.</li><li>The notes will mature on January 15, 2031 unless earlier converted, redeemed or repurchased.</li></ul>Forward-Looking StatementsThis release may contain &#34;forward-looking statements&#34; within the meaning of applicable securities laws regarding events or conditions that may occur in the future (including expectations with respect to the offering and the capped call transactions; expectations that the Company will be able to realize on proceeds from the capped call; the potential impact of the foregoing or related transactions on dilution to the common shares and the market price of the common shares or the trading price of the notes; expectations relating to the Company's project development plans and strategy; and the anticipated use of proceeds from the offering) and are based on current expectations that, while considered reasonable by management at this time, inherently involve a number of significant business, economic and competitive risks, uncertainties and contingencies.
