(&#34;Ur-Energy&#34; or the &#34;Company&#34;) (NYSE American:URG)(TSX:URE), today announced the pricing of $100 million aggregate principal amount of 4.75% Convertible Senior Notes due 2031 (the &#34;notes&#34;) in a private placement (the &#34;offering&#34;) to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the &#34;Securities Act&#34;).In addition, Ur-Energy granted the initial purchasers of the notes an option to purchase, during a 13-day period beginning on, and including, the date on which the notes are first issued, up to an additional $20 million aggregate principal amount of notes. The offering is expected to close on December 15, 2025, subject to the satisfaction of customary closing conditions.The notes will be general senior unsecured obligations of Ur-Energy and will accrue interest payable semiannually in arrears on January 15th and July 15th of each year, beginning on July 15, 2026, at a rate of 4.75% per year. The Notes will mature on January 15, 2031, unless earlier converted, redeemed or repurchased.Ur-Energy estimates that the net proceeds from the offering will be approximately $95.5 million (or approximately $114.8 million if the initial purchasers exercise their option to purchase additional notes in full) after deducting the initial purchasers' discounts and commissions and estimated offering expenses payable by Ur-Energy. Ur-Energy expects to use the net proceeds from the offering (i) to pay the approximately $13.9 million cost of the capped call transactions (as described below) (or approximately $16.6 million if the initial purchasers exercise their option to purchase additional notes in full) to be entered into with certain financial institutions (the &#34;option counterparties&#34;) and (ii) for project development and general corporate purposes. If the initial purchasers exercise their option to purchase additional notes, Ur-Energy expects to use a portion of the net proceeds from the sale of the additional notes to enter into additional capped call transactions with the option counterparties and the remaining net proceeds for the purposes described above.The notes will be convertible at the option of the holders in certain circumstances. The notes will be convertible into cash, common shares, no par value, of Ur-Energy (&#34;common shares&#34;) or a combination of cash and common shares, at Ur-Energy's election. The initial conversion rate is 576.7013 common shares per $1,000 principal amount of notes (equivalent to an initial 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 on December 10, 2025), and will be subject to adjustments in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date of the notes or if Ur-Energy delivers a notice of redemption, Ur-Energy will, in certain circumstances, increase the conversion rate of the notes for a holder who elects to convert its notes in connection with such a corporate event or convert its notes called (or deemed called) for redemption in connection with such notice of redemption, as the case may be.Ur-Energy may not redeem the notes prior to January 22, 2029, except upon the occurrence of certain changes to the laws governing withholding taxes as described below. Ur-Energy may redeem for cash all or any portion of the notes (subject to the partial redemption limitation described below), at its option, on or after January 22, 2029, if the last reported sale price of the common shares has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which Ur-Energy provides notice of redemption. Ur-Energy may also redeem for cash all but not part of the notes, at its option, subject to certain conditions, upon the occurrence of certain changes to the laws governing withholding taxes. Redemptions of notes, in either case, shall be at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. If Ur-Energy redeems less than all of the outstanding notes, at least $25 million aggregate principal amount of notes must be outstanding and not subject to redemption as of, and after giving effect to, delivery of the relevant notice of redemption.If Ur-Energy undergoes a &#34;fundamental change&#34; (as defined in the indenture governing the notes), then Ur-Energy will, subject to certain conditions and except as described in the indenture governing the notes, be required to make an offer to holders to repurchase for cash all or any portion of their notes in principal amounts of $1,000 or an integral multiple thereof. The fundamental change repurchase price will be equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.In connection with the pricing of the notes, Ur-Energy entered into privately negotiated cash-settled capped call transactions with the option counterparties. The capped call transactions will cover, subject to anti-dilution adjustments substantially similar to those applicable to the notes, the number of common shares initially underlying the notes. The capped call transactions are expected generally to compensate (through the payment of cash to Ur-Energy) for the potential economic dilution upon any conversion of notes and/or offset any cash payments Ur-Energy is required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap.The cap price of the capped call transactions relating to the notes is initially $2.72, which represents a premium of 100% over the last reported sale price of the common shares on the NYSE American on December 10, 2025, and is subject to certain adjustments under the terms of the capped call transactions.In connection with establishing their initial hedges of the capped call transactions, Ur-Energy expects that the option counterparties or their respective affiliates will enter into various derivative transactions with respect to the common shares and/or purchase common shares concurrently with or shortly after the pricing of the notes, including with, or from, certain investors in the notes. This activity could increase (or reduce the size of any decrease in) the market price of common shares or the trading price of the notes at that time.In addition, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to the common shares and/or purchasing or selling common shares or other securities of Ur-Energy in secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and are likely to do so during the 50-trading day period beginning on the 51st scheduled trading day prior to the maturity date of the notes and, to the extent the Company exercises the relevant election under the capped call transactions, following any earlier conversion, redemption or repurchase of the notes). This activity could also cause or avoid an increase or a decrease in the market price of the common shares or the notes, which could affect a holder's ability to convert the notes and, to the extent the activity occurs during any observation period related to a conversion of notes, it could affect the number of common shares, if any, and the value of the consideration that a holder will receive upon conversion of its notes.The notes and the common shares issuable upon conversion of the notes, if any, have not been registered under the Securities Act, any state securities laws or the securities laws of any other jurisdiction, and unless so registered, may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons, except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws. Offers and sales in Canada will be made only pursuant to exemptions from the prospectus requirements of applicable Canadian provincial and territorial securities laws. The notes issued and the common shares issuable upon the conversion of notes, if any, to purchasers in Canada will be subject to a statutory hold period in accordance with applicable Canadian provincial and territorial securities laws. The offering is subject to final acceptance of the Toronto Stock Exchange (&#34;TSX&#34;). In obtaining TSX conditional approval, Ur-Energy intends to rely on the Exemptions for Eligible Interlisted Issuers set forth in Section 602.1 of the TSX Company Manual, which provide that the TSX will not apply its standards to certain transactions involving &#34;Eligible Interlisted Issuers&#34; on a &#34;Recognized Exchange&#34; (each as defined in the TSX Company Manual), such as the NYSE American.This press release is neither an offer to sell nor a solicitation of an offer to buy any of the securities being offered in the offering nor shall it constitute an offer, solicitation or sale of any securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to the registration or qualification thereof under the securities laws of any such state or jurisdiction.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 statements concerning the anticipated completion of the offering and capped call transactions, 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, 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.
