Item 9A. CONTROLS AND PROCEDURES (a) Evaluation of Disclosure Controls and Procedures As of the fiscal year ended December 31, 2025, under the supervision of the Chief Executive Officer and the Chief Financial Officer, the Company evaluated the effectiveness of its disclosure controls and procedures, as such term is defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”). Based on this evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that the Company’s disclosure controls and procedures are effective to ensure that information the Company is required to disclose in reports that are filed or submitted under the Exchange Act: (1) is recorded, processed and summarized effectively and reported within the time periods specified in SEC rules and forms, and (2) is accumulated and communicated to Company management, including the Chief Executive Officer and the Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. The Company’s disclosure controls and procedures include components of internal control over financial reporting. No matter how well designed and operated, internal controls over financial reporting can provide only reasonable, but not absolute, assurance that the control system’s objectives will be met. (b) Management’s Report on Internal Control Over Financial Reporting Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, the Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with US GAAP. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Because of the inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. As of December 31, 2025, management assessed the effectiveness of the Company’s internal control over financial reporting based on the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its assessment using those criteria, management concluded that the Company maintained effective internal control over financial reporting as of December 31, 2025. (c) Attestation Report of Registered Public Accounting Firm This annual report does not include an attestation report of the Company’s registered public accounting firm regarding internal controls over financial reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to law, rules and regulations that permit us to provide only management’s report in this annual report. 73 Table of Contents (d) Changes in Internal Controls over Financial Reporting No changes in our internal control over financial reporting occurred during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ​ Item 9B.

Headquartered in Casper, Wyoming Consolidated Financial Statements December 31, 2025 (expressed in thousands of U.S. dollars unless otherwise indicated) ​ F-2 Table of Contents Report of Independent Registered Public Accounting Firm Shareholders and Board of Directors Ur-Energy Inc. Casper, Wyoming Opinion on the Consolidated Financial Statements We have audited the accompanying consolidated balance sheets of Ur-Energy Inc. (the “Company”) as of December 31, 2025 and 2024, the related consolidated statements of operations and comprehensive loss, changes in shareholders’ equity, and cash flows for each of the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for the years then ended , in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matters ​ The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate opinion on the critical audit matters or on the accounts or disclosures to which they relate. ​ F-3 Table of Contents Assessment of impairment indicators of capital assets As described in Notes 2 and 10 to the consolidated financial statements, capital assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts of the asset may not be recoverable (“impairment indicators”). The net book value of the Company’s capital assets was $49.7 million as of December 31, 2025. Management applies significant judgment to assess capital assets for impairment indicators that could give rise to the requirement to conduct a recoverability test. Circumstances that could trigger a recoverability test include, but are not limited to: significant decreases in the market price of the asset; significant adverse changes in the business climate or legal factors; significant changes in expected capital, operating, or reclamation costs; current period cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and current expectation that the asset will more likely than not be sold or disposed of significantly before the end of its estimated useful life. Management did not identify impairment indicators that would require a recoverability test for the year ended December 31, 2025. We identified management’s assessment of impairment indicators of capital assets as a critical audit matter. Judgment is required by management when assessing whether there were indicators of impairment related to the Company’s capital assets, specifically related to assessing whether there were: (i) significant adverse changes in the business climate including significant adverse changes in legal factors; (ii) significant changes in expected capital, operating or reclamation costs; and (iii) significant decreases in the market price of the capital assets. Auditing these elements involved especially subjective auditor judgment due to the nature and extent of audit effort required to address this matter. The primary procedures we performed to address this critical audit matter included: ​ ● Evaluating whether there were significant adverse changes in the business climate by considering external market and industry data. ● Evaluating whether there were significant adverse changes in legal factors. ● Evaluating whether there were significant changes in expected capital costs, operating costs or reclamation costs through consideration of evidence obtained in other areas of the audit. ● Evaluating whether there were significant decreases in the market price of the capital assets by considering any prolonged declines in the Company’s market capitalization. ​ Accounting and Valuation for Convertible Notes, Conversion Option Derivative and Capped Call Derivative ​ As described in Notes 11, 13 and 14 to the consolidated financial statements, in December 2025 the Company issued a $120 million aggregate principal amount of convertible senior notes due 2031 (the “Convertible Notes”) which included an embedded conversion feature (the “Conversion Option Derivative”) that met the criteria for bifurcation and was recognized as a separate derivative instrument valued at $52.3 million as of December 31, 2025. In connection with the issuance of the Convertible Notes, the Company entered into a capped call transaction (the “Capped Call Derivative”) valued at $15.1 million as of December 31, 2025. Both the Conversion Option Derivative and Capped Call Derivative are remeasured each reporting period with changes in fair value being recorded within the consolidated statement of operations and comprehensive loss. ​ We identified the Company’s accounting and valuation for the Convertible Notes, Conversion Option Derivative, and Capped Call Derivative, as a critical audit matter. Determining whether the Conversion Option Derivative met the criteria for bifurcation to be recognized as a separate derivative instrument and whether the Conversion Option Derivative and the Capped Call Derivative met the criteria for equity classification involved the use of significant judgment in the application of complex accounting standards. Additionally, subsequent to assessment of the liability classification of the Conversion Option Derivative, and the asset classification of the Capped Call Derivative, management used key assumptions in determining their fair values, including volatility. Auditing these elements involved especially challenging, subjective, and complex auditor judgment due to the nature and extent of the audit effort required to evaluate management’s application of complex accounting standards to these elements, including the extent of specialized skills or knowledge needed. ​ F-4 Table of Contents The primary procedures we performed to address this critical audit matter included: ​ • Reading and analyzing the relevant agreements to identify relevant terms and conditions that affect whether the Conversion Option Derivative embedded within the Convertible Notes met the criteria to be bifurcated and recognized as a separate derivative instrument and whether the Conversion Option Derivative and the Capped Call Derivative met the criteria for equity classification. • Utilizing firm personnel with expertise in the relevant technical accounting, to assist in evaluating the Company’s conclusions regarding whether the Conversion Option Derivative met the criteria to be bifurcated and recognized as a separate derivative instrument and whether the Conversion Option Derivative and the Capped Call Derivative met the criteria for equity classification. • Utilizing personnel with specialized knowledge and skills in valuation to assist in evaluating the reasonableness of the volatility assumption used in the fair value calculations. ​ ​ /s/ BDO USA, P.C.

Notes to Consolidated Financial Statements December 31, 2025 (expressed in thousands of U.S. dollars, except share data, unless otherwise indicated) ​ ​ 1. Nature of Operations Ur-Energy Inc. (the “Company”) was incorporated on March 22, 2004 under the laws of the Province of Ontario. The Company continued under the Canada Business Corporations Act on August 8, 2006. The Company is an exploration stage issuer, as defined by the U.S. Securities Exchange Commission (“SEC”). The Company is engaged in uranium mining and recovery operations, with activities including the acquisition, exploration, development, and production of uranium mineral resources located in Wyoming. The Company commenced uranium production at its Lost Creek Project in Wyoming in 2013. Due to the nature of the uranium recovery methods used by the Company, the Company has not determined whether its properties contain mineral reserves. The recoverability of amounts recorded for mineral properties is dependent upon the discovery of economic resources, the ability of the Company to obtain the necessary financing to develop the properties and upon attaining future profitable production from the properties or sufficient proceeds from disposition of the properties. Furthermore, the Company currently has no plans to establish proven or probable reserves for any of its uranium projects for which the Company plans on utilizing in situ recovery (“ISR”) mining, such as the Lost Creek Property or the Shirley Basin Project, which would require completion of a bankable feasibility study for each project. As a result, and even though the Company commenced recovery of uranium at the Lost Creek Project in August 2013, the Company remains an exploration stage issuer, and will continue to remain an exploration stage issuer until such time as proven or probable mineral reserves have been established. 2. Summary of Significant Accounting Policies Basis of presentation These consolidated financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and include all the assets, liabilities and expenses of the Company and its wholly owned subsidiaries Ur-Energy USA Inc.; NFU Wyoming, LLC; Lost Creek ISR, LLC; and Pathfinder Mines Corporation. All inter-company balances and transactions have been eliminated upon consolidation. Ur-Energy Inc. and its wholly owned subsidiaries are collectively referred to herein as the “Company.” Exploration stage Because the Company commenced recovery of uranium at the Lost Creek Project without having established proven and probable reserves, any uranium resources established or extracted from the Lost Creek Project should not be in any way associated with having established proven or probable mineral reserves. Use of estimates The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The most significant estimates management makes in the preparation of these consolidated financial statements relate to the fair value of stock-based compensation, warrant liability, and capped call derivative using the factors associated with the Black-Scholes calculations, the fair value of the conversion option using the factors associated with the binomial lattice model, the estimation of the amount of recoverable uranium included in the in-process inventory, the impairment of long-lived assets including mineral properties, the estimation of the fair market value of non-produced inventory and the inventory derivative obligation, the estimation of inputs used to calculate asset retirement obligations such as credit-adjusted risk free discount rates and inflation rates, total cost and the time until the asset retirement commences and the offset of future income taxes through deferred tax assets. Actual results could differ from those estimates. ​ F-10 Table of Contents Ur-Energy Inc. Notes to Consolidated Financial Statements December 31, 2025 (expressed in thousands of U.S. dollars, except share data, unless otherwise indicated) ​ ​ Functional and reporting currency ​ The reporting currency for these consolidated financial statements is the U.S. dollar . Items included in the consolidated financial statements of each of the Company’s entities are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The functional currency of Ur-Energy Inc. is the Canadian dollar and the functional currency for Ur-Energy USA Inc. and its subsidiaries, all of which are wholly owned subsidiaries, is the U.S. dollar . ​ Cash and cash equivalents Cash and cash equivalents consist of cash balances and highly liquid investments with original maturities of three months or less. Cash equivalents are held for the purpose of meeting short-term cash commitments rather than for investment or other purposes. Restricted cash and cash equivalents Cash and cash equivalents that secure various instruments related to surety bonds, which secure reclamation obligations and a state lease, are shown as restricted cash. Restricted cash and cash equivalents are excluded from cash and cash equivalents and are included in non-current assets. Trade receivables Trade receivables are recorded at invoiced amounts. The Company has no history of credit losses and has contracts with its customers that specify payment terms of 30 days or less with recourse provisions if payments are not made on a timely basis. Due to the nature of its products and services, the Company’s sales are limited to a small number of customers who have high credit scores and stable businesses. Lease receivables The Company originates direct finance leases for drilling equipment. The residual value of the direct finance leases is specified in the lease agreement. Residual value payments owed to the Company at the conclusion of these leases amounted to $ 0.4 million at December 31, 2025, and are included in the carrying value of direct finance leases. Unearned lease revenue represents the difference between the Company’s investment in the property and the gross investment in the lease. Unearned revenue is accrued over the life of the lease using the effective interest method. Inventory In-process inventory represents uranium that has been extracted from the wellfield and captured in the processing plant and is currently being transformed into a saleable product. Plant inventory is triuranium octoxide (“U 3 O 8 ”) that is contained in yellowcake, which has been dried and packaged in drums, but not yet shipped to the third-party conversion facility. Conversion facility inventory is U 3 O 8 that has been shipped to the conversion facility. The amount of U 3 O 8 in the conversion facility inventory includes the amount of U 3 O 8 contained in drums shipped to the conversion facility plus or minus any final weighing and assay adjustments per the terms of our uranium supplier’s agreement with the conversion facility. Inventory values are calculated on a weighted average basis. The Company’s inventories are measured at the lower of cost or net realizable value (“NRV”) and reflect the U 3 O 8 content in various stages of the production and sales process including in-process inventory, plant inventory, and conversion facility inventory. F-11 Table of Contents Ur-Energy Inc. Notes to Consolidated Financial Statements December 31, 2025 (expressed in thousands of U.S. dollars, except share data, unless otherwise indicated) ​ ​ Mineral properties Acquisition costs of mineral properties are capitalized. Amortization is calculated on a straight-line basis as there are no proven reserves. The initial estimated life for the Lost Creek Project was 10 years which was used to amortize the mineral property acquisition costs. If properties are abandoned or sold, they are written off. If properties are impaired in value, the costs of the properties are written down to their estimated fair value at that time. Exploration, evaluation, and development costs Exploration and evaluation costs consist of annual lease and claim maintenance fees, and the associated costs of the exploration, evaluation, and regulatory departments as well as exploration costs including drilling and analysis on properties that have not reached the permitting or operations stage. These costs are expensed and included in operating costs. Development expenses relate to the Company’s Lost Creek, LC East, Lucky Mc and Shirley Basin projects, which are more advanced in terms of economic assessment, permitting, and operational status. Development expenses include all costs associated with exploring, delineating, and permitting the projects; and the costs associated with the construction and development of permitted mine units including wells, pumps, piping, header houses, roads, and other infrastructure related to the preparation of a mine unit to begin extraction operations as well as the cost of drilling and completing disposal wells. These costs are expensed and included in operating costs. Equipment purchases and costs associated with constructing the plant building as well as mine site access roads and the plant site are capitalized and amortized on a straight line basis over the initially estimated life of the mine. Production stage issuers, as defined by the SEC, having established proven and probable reserves, typically capitalize expenditures relating to ongoing development activities, with corresponding depletion calculated over proven and probable reserves using the units-of-production method. Depletion is then allocated to inventory and as the inventory is sold, to cost of sales. We are an exploration stage issuer which has resulted in the Company reporting larger losses than if we were a production stage issuer, due to the expensing, instead of capitalization, of expenditures relating to ongoing mine development activities. Additionally, there would be no corresponding depletion allocated to future periods of the Company since those costs had been expensed previously, resulting in both lower inventory costs and cost of sales, and results of operations with higher gross profit and lower gross loss than if we would have been in the production stage. As a result, our consolidated financial statements may not be directly comparable to the financial statements of production stage issuers. Capital assets Property, plant, and equipment assets, including machinery, processing equipment, enclosures, and vehicles are recorded at cost including acquisition, installation costs, and expenditures that extend the life of such assets. The enclosure costs include both the building enclosure and the processing equipment necessary for the extraction of uranium from impregnated water pumped in from the wellfield to the packaging of uranium yellowcake for delivery into sales. These enclosure costs are combined as the equipment and related installation associated with the equipment is an integral part of the structure itself. The costs of self-constructed assets include direct construction costs, direct overhead, and allocated interest during the construction phase. Depreciation is calculated using a declining balance method for most assets, except the plant enclosure and related equipment. Depreciation of the plant enclosure and related equipment is calculated on a straight-line basis. Estimated lives for depreciation purposes range from three years for computer equipment and software to 20 years for the plant enclosure and the nameplate life of the related equipment. F-12 Table of Contents Ur-Energy Inc. Notes to Consolidated Financial Statements December 31, 2025 (expressed in thousands of U.S. dollars, except share data, unless otherwise indicated) ​ ​ Impairment of long-lived assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Management applies significant judgment to assess mineral properties and capital assets for impairment indicators that could give rise to the requirement to conduct a formal impairment test. Circumstances that could trigger a review include, but are not limited to: significant decreases in the market price of the asset; significant adverse changes in the business climate or legal factors; significant changes in expected capital, operating, or reclamation costs; current period cash flow or operating losses combined with a history of losses or a forecast of continuing losses associated with the use of the asset; and current expectation that the asset will more likely than not be sold or disposed of significantly before the end of its estimated useful life. When potential impairment is indicated, management calculates the estimated undiscounted future net cash flows relating to the asset or asset group using estimated future prices, recoverable resources and operating, capital, and reclamation costs. When the carrying value of an asset exceeds the related undiscounted cash flows, the asset is written down to its estimated fair value, which is determined using discounted future net cash flows, or other measures of fair value. Changes in these estimates may materially impact the carrying value of the assets. Management did not identify impairment indicators that would require a formal impairment test for the years ended December 31, 2025 and 2024. Lost Creek has been the Company’s sole source of uranium concentrates produced and sold to generate sales revenues since 2013. The economic viability of the Company’s mining activities, including the expected duration and profitability of Lost Creek and of any future ISR mines, such as Shirley Basin, has many risks and uncertainties. These include, but are not limited to: (i) a significant, prolonged decrease in the market price of uranium; (ii) difficulty in marketing and/or selling uranium concentrates; (iii) significantly higher than expected capital costs to construct the mine and/or processing plant; (iv) significantly higher than expected extraction costs; (v) significantly lower than expected uranium extraction; (vi) significant delays, reductions or stoppages of uranium extraction activities; and (vii) the introduction of significantly more stringent regulatory laws and regulations. Long-term debt Long-term debt is carried at amortized cost. Debt issuance costs, debt premiums and discounts are included in the long-term debt balance and amortized using the effective interest method over the contractual terms of the long-term debt. Derivative financial instruments The Company records derivative financial instruments on the consolidated balance sheets at fair value as either an asset or a liability with changes in fair value recognized in earnings. Derivative financial instruments are classified as either current or non-current based upon the related classification of the host contract. The inventory derivative obligation is adjusted to fair value using the average current spot uranium price before subtracting the related cash deposit held by the lender. The warrant liability and capped call derivative are adjusted to fair value using the Black Scholes valuation model. The conversion option derivative is adjusted to fair value using a binomial lattice valuation model. Asset retirement obligations For mining properties, various federal and state mining laws and regulations require the Company to reclaim the surface areas and restore groundwater quality to the pre-existing quality or class of use after the completion of mining. The Company records the fair value of an asset retirement obligation as a liability in the period in which it incurs an obligation associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development and/or normal use of the assets. F-13 Table of Contents Ur-Energy Inc. Notes to Consolidated Financial Statements December 31, 2025 (expressed in thousands of U.S. dollars, except share data, unless otherwise indicated) ​ ​ Asset retirement obligations consist of estimated final well abandonments, plant closure and removal, and the associated reclamation and restoration costs to be incurred by the Company in the future. The estimated value of the asset retirement obligation is based on the current estimated reclamation cost escalated at an inflation rate and then discounted at a credit adjusted risk-free discount rate. This liability is recorded, and a corresponding asset is capitalized as part of the cost of the related asset. The asset is amortized over its remaining estimated productive life. The liability accretes until it reaches the estimated future reclamation cost and remains until the Company settles the obligation. Financing lease liabilities and right of use assets We categorize leases with contractual terms longer than twelve months as operating or financing leases. Financing leases are generally those leases that allow us to substantially utilize or pay for the entire asset over its estimated life. Right of use assets acquired under finance leases are recorded in capital assets (net). All other leases are categorized as operating leases. Our leases generally have terms that range from three to five years for equipment. Right of use assets are recognized based on the initial present value of the fixed lease payments plus any direct costs from executing the leases or lease prepayments. Finance lease right of use assets are amortized within operating expenses on a straight-line basis over the lease term. The interest component of a finance lease is included in interest expense and recognized using the effective interest method over the lease term. Lease liabilities are recognized at the present value of the fixed lease payments. In determining the present value of lease payments, we use our incremental borrowing rate based on the information available at the lease commencement date. Revenue recognition Our revenues are primarily derived from the sale of U 3 O 8 under either long-term (deliveries typically in two to five years) or spot (immediate delivery) contracts with our customers. The contracts specify the quantity to be delivered, the price or specific calculation method of the price, payment terms, and the year(s) of the delivery. When a customer delivery is approved, the Company notifies the third-party conversion facility with instructions for a title transfer to the customer. For sales of U 3 O 8 , the single performance obligation is met, the transaction price is known, and revenue is recognized at the time of the transfer of control of the agreed-upon quantities to the customer at the third-party conversion facility. Stock-based compensation Stock-based compensation cost from the issuance of stock options and restricted share units (“RSUs”) is measured at the grant date based on the fair value of the award and is recognized over the related service period using the straight-line method. Stock-based compensation costs are charged to cost of sales, exploration and evaluation, development, and general and administrative expense on the same basis as other compensation costs. The Company does not estimate the potential for forfeiture of stock-based compensation awards when determining the fair value of awards on the grant date. In the case of a stock-based compensation award that is either canceled or forfeited prior to vesting, the amortized expense associated with the unvested award is reversed. Awards of options that provide for an exercise price that is not denominated in: (a) the currency of a market in which a substantial portion of the Company's equity securities trades in, (b) the currency in which the employee's pay is denominated, or (c) the functional currency of the employer’s operations, are required to be classified as liabilities. The Company previously used the substantial portion trading exception to classify the Canadian dollar denominated options awards issued to U.S. based employees as equity. However, the decrease in the number of shares traded in the Canadian market for the Company’s trading symbol, URE, as compared to the number of shares traded on the NYSE American for the Company’s trading symbol, URG, following our July 29, 2024 underwritten public offering resulted in the reclassification of outstanding stock options that were issued to US based employees which were denominated in Canadian dollars from equity-classified to liability-classified options (see note 19). The reclassification is accounted for as a share option modification in accordance with FASB’s ASC 718 – Compensation – Stock F-14 Table of Contents Ur-Energy Inc. Notes to Consolidated Financial Statements December 31, 2025 (expressed in thousands of U.S. dollars, except share data, unless otherwise indicated) ​ ​ Compensation (“ASC 718”). Under ASC 718, when an award is reclassified from equity to liability, if at the reclassification date the original vesting conditions are expected to be satisfied, then the minimum amount of compensation cost to be recognized is based on the grant date fair value of the original award. Fair value changes below this minimum amount are recorded in additional paid-in capital. For each reporting period after the modification date, the stock option liability is adjusted so that it equals the portion of the requisite service provided multiplied by the modified award’s fair value at the end of the reporting period. Increases in the fair value of the liability in excess of the minimum grant date compensation cost described above are recognized as share-based compensation in operating expenses in the consolidated statements of operations and comprehensive loss. For all grants of liability-classified option awards, the compensation cost is remeasured at each reporting period until the settlement date. Income taxes The Company accounts for income taxes under the asset and liability method which requires the recognition of deferred income tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. The Company provides a valuation allowance on deferred tax assets unless it is more likely than not that such assets will be realized. Earnings and loss per share calculations Diluted earnings per common share are calculated by including all options that are in-the-money based on the average stock price for the period as well as RSUs that are outstanding. The treasury stock method was applied to determine the dilutive number of options. Warrants are included only if the exercise price is less than the average stock price for the quarter. The convertible notes utilize the if-converted method which assumes convertible securities are converted into common shares and the numerator is reduced by interest expense incurred. In periods of loss, the diluted loss per common share is equal to the basic loss per common share due to the anti-dilutive effect of outstanding stock awards and convertible securities. All share awards and convertible securities were anti-dilutive for all periods presented. Segments We regularly review our reportable segments and the approach used by management to evaluate performance and allocate resources. The Company operates as a single operating segment . Our determination that we operate as a single segment is consistent with the financial information as presented in the consolidated statements of operations and comprehensive loss, which is regularly reviewed by the chief operating decision maker (CODM), considered to be the Chief Executive Officer, Chief Operating Officer, Chief Financial Officer, Vice President Finance, and General Counsel, for purposes of evaluating performance, allocating resources, setting incentive compensation targets, and planning and forecasting for future periods. Our CODM allocates resources and assesses financial performance on a consolidated basis with consideration given to key financial metrics, including gross profit (loss), operating loss, and net loss. All revenues are earned within the U.S., and all of the Company’s long-lived assets are within the U.S..

Fair value is the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation models involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. The valuation hierarchical levels are based upon the transparency of the inputs to the valuation of the asset or liability as of the measurement date. The three levels are defined below: ​ Level 1 - Valuations based on quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 - Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. Level 3 - Valuations based on inputs that are unobservable and significant to the overall fair value measurement. ​ The Company's financial assets and liabilities as of December 31, 2025 and 2024 include cash, trade receivables, lease receivables, restricted cash, accounts payable and accrued liabilities, and lease liabilities. These financial assets and liabilities are carried at cost, which approximates fair value due to their short-term maturities. Long-term debt is also carried at cost in the consolidated balance F-16 Table of Contents Ur-Energy Inc.

Financial instruments, including the inventory derivative obligation, warrant liability, conversion option derivative, and capped call derivative are adjusted to fair value on a recurring basis. ​ The Company has certain non-financial assets that are measured at fair value on a non-recurring basis when there is an indicator of impairment, and they are recorded at fair value only when impairment is recognized. These assets include mineral properties and capital assets. The Company did not record impairment to any non-financial assets in the years ended December 31, 2025 and 2024 and does not have any non-financial liabilities measured and recorded at fair value on a non-recurring basis. ​ The following table sets forth the estimated fair values and fair value hierarchies of the Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2025 and 2024: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Hierarchy as of December 31, 2025 ​ Fair Value Hierarchy as of December 31, 2024 ​ ​ Level 1 ​ Level 2 ​ Level 3 ​ Total ​ Level 1 ​ Level 2 ​ Level 3 ​ Total ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial instrument assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash equivalents ​ 2,938 ​ — ​ — ​ 2,938 ​ 65,096 ​ — ​ — ​ 65,096 Restricted cash equivalents ​ 11,472 ​ — ​ — ​ 11,472 ​ 11,011 ​ — ​ — ​ 11,011 Capped call derivative ​ — ​ 15,108 ​ — ​ 15,108 ​ — ​ — ​ — ​ — ​ ​ 14,410 ​ 15,108 ​ — ​ 29,518 ​ 76,107 ​ — ​ — ​ 76,107 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial instrument liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Inventory derivative obligation (net) ​ — ​ 16,638 ​ — ​ 16,638 ​ — ​ 14,408 ​ — ​ 14,408 Warrant liability ​ — ​ 1,541 ​ — ​ 1,541 ​ — ​ 2,529 ​ — ​ 2,529 Stock option liabilities ​ — ​ 1,346 ​ — ​ 1,346 ​ — ​ 1,758 ​ — ​ 1,758 Conversion option derivative ​ — ​ — ​ 52,258 ​ 52,258 ​ — ​ — ​ — ​ — ​ ​ — ​ 19,525 ​ 52,258 ​ 71,783 ​ — ​ 18,695 ​ — ​ 18,695 ​ ​ ​ ​ 3. New Accounting Pronouncements Income Tax Disclosures In December 2023, the FASB issued ASU 2023-09, which requires additional disaggregation of the reconciliation between the statutory and effective tax rate for an entity and of income taxes paid. The amendments improve the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, and is applied either prospectively or retrospectively at the option of the Company. The Company adopted this standard retrospectively on January 1, 2025, which resulted in expanded income tax disclosures in these consolidated financial statements. ​ Reporting Comprehensive Income ​ In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures, which includes amendments to require the disclosure of certain specific costs and expenses that are included in a relevant expense caption on the face of the income statement. Specific costs and expenses that would be required to be disclosed include: purchases of inventory, employee compensation, depreciation and intangible asset amortization. Additionally, a qualitative description of other items is required, equal to the difference between the relevant expense caption and the separately disclosed specific costs. The amendments in ASU 2024-03 are effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, and are applied either prospectively or retrospectively at the option of the Company. We are evaluating the impact of the amendments on our consolidated financial statements and disclosures. F-17 Table of Contents Ur-Energy Inc.

Assets acquired in this transaction include the Lost Creek Project, other Wyoming properties, and development databases. NFU Wyoming, LLC was acquired for aggregate consideration of $ 20 million plus interest. Since 2005, the Company has increased its holdings adjacent to the initial Lost Creek acquisition through staking additional claims and making additional property purchases and leases. There is a royalty on each of the State of Wyoming sections under lease at the Lost Creek, LC West and EN Projects, as required by law. We are not recovering U 3 O 8 within the State section under lease at Lost Creek and are not subject to royalty payments currently. Other royalties exist on certain mining claims at the LC South, LC East and EN Projects. There are no royalties on the mining claims in the Lost Creek, LC North, or LC West Projects. Shirley Basin Project The Company acquired additional Wyoming properties in 2013 when Ur-Energy USA Inc. purchased 100 % of Pathfinder Mines Corporation (“Pathfinder”). Assets acquired in this transaction include the Shirley Basin Project, other Wyoming properties, and development databases. Pathfinder was acquired for aggregate consideration of $ 6.7 million, the assumption of $ 5.7 million in estimated asset reclamation obligations, and other consideration. Other U.S. Properties Other U.S. properties include the acquisition costs of several prospective mineralized properties, which the Company continues to maintain through claim payments, lease payments, and other holding costs in anticipation of future exploration efforts. ​ F-20 Table of Contents Ur-Energy Inc.

Capped Call Derivative As discussed in note 2, the Company’s functional currency is the Canadian dollar and as discussed in note 13, the capped call transaction (the “Capped Call”) cap price is $ 2.72 per common share. Because the Capped Call is priced in U.S. dollars, relative to the Company’s functional currency, US GAAP requires the Capped Call to be accounted for as a stand-alone derivative instrument (the "Capped Call Derivative"). The Capped Call Derivative is recorded at fair value on the Company’s consolidated balance sheets and mark-to-market changes in fair value are recorded in earnings. Using Level 2 inputs of the fair value hierarchy under US GAAP, the Capped Call Derivative is measured and recorded at fair value using the Black-Scholes model described below as there is no active market for the Capped Call. ​ The fair value of the Capped Call Derivative asset was $ 16.6 million as of December 15, 2025, the issuance date of the Convertible Notes and Capped Call, and was based on the $ 16.6 million option premium paid to the counterparty banks. The Capped Call Derivative fair value was $ 15.1 million at December 31, 2025, which resulted in a $ 1.5 million mark-to-market loss for the year ended December 31, 2025. The Capped Call Derivative fair value was determined using a fair value model with the following assumptions: ​ ​ ​ ​ ​ ​ ​ Capped Call Derivative Fair Value Model Assumptions ​ December 31, 2025 ​ ​ ​ Expected life (years) ​ 5.0 Volatility ​ 49.8 % - 70.4 % Risk free rate ​ 3.70 % Expected dividend rate ​ —% Exercise prices (capped call floor) ​ $ 1.73 Exercise prices (capped call ceiling) ​ $ 2.72 Current market price ​ $ 1.39 ​ ​ F-21 Table of Contents Ur-Energy Inc.

Long-Term Debt Convertible Notes On December 15, 2025, the Company issued $ 120.0 million aggregate principal amount of Convertible Senior Notes (the “Convertible Notes”). The Convertible Notes bear interest at a rate of 4.75 %, annually, payable semiannually in arrears, beginning July 15, 2026, and mature on January 15, 2031. The net proceeds from the offering of the Convertible Notes were approximately $ 114.8 million, after deducting debt issuance costs. The Company used $ 16.6 million of the net proceeds from the Convertible Notes offering to pay the costs of entering into a Capped Call transaction in connection with the Convertible Notes. The Convertible Notes were issued pursuant to, and are governed by, an indenture, dated December 15, 2025 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”). The initial conversion rate for the Convertible Notes is 576.7013 shares per $1,000 principal amount of the Convertible Notes, which represents an initial conversion price of approximately $ 1.73 per common share, and is subject to adjustment upon the occurrence of certain specified events as set forth in the Indenture. Upon conversion, the Company will pay or deliver, as applicable, cash, common shares or a combination of cash and common shares. Upon the occurrence of a “make-whole fundamental change” (as defined in the Indenture), the Company will in certain circumstances increase the conversion rate for a specified period of time. In addition, upon the occurrence of a “fundamental change” (as defined in the Indenture), holders of the Convertible Notes may require the Company to repurchase their Convertible Notes at a cash repurchase price equal to the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest, if any. Prior to October 15, 2030, a holder may convert all or any portion of its Convertible Notes at any time after March 31, 2026, but only if the last reported sale price per common share for at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130 % of the conversion price on each applicable trading day. On or after October 15, 2030, a holder may convert all or any portion of its Convertible Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date. The Convertible Notes may be redeemed, in whole or in part, at the Company’s option at any time, and from time to time, on or after January 22, 2029 and on or before the 30th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest, if any, but only if the last reported sale price per common share exceeds 130 % of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice, and (ii) the trading day immediately before the date the Company sends such notice. The indenture contains specified events of default and our failure to pay principal, interest or other amounts when due or within the relevant grace period on our Convertible Notes would constitute an event of default under the Indenture, which could result in an acceleration of the maturity of the Convertible Notes. The Convertible Notes do not contain sinking fund requirements and maturities for each of the following five years are nil . The $ 120.0 million principal amount is due and payable in January 2031, should the Convertible Notes not be settled or converted prior to their maturity date. F-22 Table of Contents Ur-Energy Inc. Notes to Consolidated Financial Statements December 31, 2025 (expressed in thousands of U.S. dollars, except share data, unless otherwise indicated) ​ ​ The Convertible Notes’ components upon issuance as of December 15, 2025 and December 31, 2025, were as follows: ​ ​ ​ ​ ​ ​ Convertible Senior Notes due January 2031 ​ December 31, 2025 ​ December 15, 2025 ​ ​ ​ ​ ​ Notes issued at face value ​ 120,000 ​ 120,000 ​ ​ ​ ​ ​ Unamortized debt discount ​ ( 48,690 ) ​ ( 49,105 ) Unamortized debt issuance costs (debt discount) ​ ( 5,205 ) ​ ( 5,249 ) Foreign exchange loss (gain) ​ 316 ​ - ​ ​ ​ ​ ​ Long-term debt, net ​ 66,421 ​ 65,646 ​ Carrying value and fair value information for the Convertible Notes from issuance through December 31, 2025 is presented below: ​ ​ ​ ​ ​ ​ ​ ​ Convertible Senior Notes due January 2031 ​ Carrying Value ​ Fair Value (1) ​ Valuation Level ​ ​ ​ ​ ​ ​ ​ Balance, December 15, 2025 ​ 65,646 ​ 85,351 ​ ​ ​ ​ ​ ​ ​ ​ ​ Amortization of debt discount ​ 459 ​ ​ ​ ​ Foreign exchange loss (gain) ​ 316 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance, December 31, 2025 ​ 66,421 ​ 85,414 ​ Level 3 (1) The reported fair value of the Convertible Notes relates only to the debt component of such security and excludes the fair value associated with the related Conversion Option Derivative that has been bifurcated and accounted for separately. Refer to note 14 for fair value information related to the Conversion Option Derivative. The Conversion Option Derivative (see note 14) is treated as a debt discount, and its initial issuance fair value amount will be amortized to interest expense with an increase to the Convertible Notes’ carrying amount over its five -year term. Using Level 3 inputs of the fair value hierarchy under US GAAP, the Conversion Option Derivative is measured and recorded at fair value using a binomial lattice model which utilizes a debt host (without) methodology. For the year ended December 31, 2025, the Company recognized Convertible Notes’ interest expense of $ 0.2 million and amortization of debt discount, inclusive of debt issuance cost amortization, of $ 0.5 million, all of which are recorded as interest expense in the consolidated statements of operations and comprehensive loss. The effective interest rate on the Convertible Notes is 19.1 %. Capped Call Transaction As discussed in note 11, in connection with the Convertible Notes issued in December 2025, the Company entered into Capped Call transactions with three counterparty banks. The Capped Call has the same term and maturity as the Convertible Notes and covers, subject to anti-dilution adjustments, the number of common shares underlying the Convertible Notes, and is expected generally to reduce the potential dilution to the common shares upon any conversion of Convertible Notes and/or offset any potential cash payments that the Company is required to make in excess of the principal amount of converted Convertible Notes, as the case may be, with such reduction and/or offset subject to a cap, based on the cap price of the Capped Call. To the extent, however, that the market price of our common shares, as measured under the terms of the Capped Call, exceeds the cap price of $ 2.72 , there would nevertheless be dilution and/or there would not be an offset of such cash payments to the extent of the excess. F-23 Table of Contents Ur-Energy Inc. Notes to Consolidated Financial Statements December 31, 2025 (expressed in thousands of U.S. dollars, except share data, unless otherwise indicated) ​ ​ Like the Convertible Notes, the Capped Call matures in January 2031. If upon exercise of the Capped Call, the market price of the Company’s common shares exceeds the $ 2.72 cap price, then the Company will receive a cash payment equal to the difference between the $ 2.72 cap price and the $ 1.73 initial conversion price multiplied by the number of common shares underlying the Convertible Notes. If the market price of the Company’s common shares is less than the cap price but higher than the initial conversion price, then the Company will receive a cash payment equal to the difference between the market price of a common share and the initial conversion price multiplied by the number of common shares underlying the Convertible Notes. If the market price of the Company’s common shares is less than the initial conversion price, no payment will be due to the Company under the Capped Call. Notes Payable On October 23, 2013, we closed a $ 34.0 million Sweetwater County, State of Wyoming, Taxable Industrial Development Revenue Bond financing program loan (“State Bond Loan”). The State Bond Loan called for payments of interest at a fixed rate of 5.75 % per annum on a quarterly basis, which commenced January 1, 2014. As amended, the principal was payable in quarterly installments with the last payment due on October 1, 2024. On March 27, 2024, the remaining $ 4.4 million balance due on the State Bond Loan was prepaid in full. The State Bond Loan was secured by all the assets of the Lost Creek Project. All releases of collateral have been obtained following the final repayment of the facility. 14. Conversion Option Derivative As discussed in note 2, the Company’s functional currency is the Canadian dollar and as discussed in note 13, the Convertible Notes’ conversion price is approximately $ 1.73 per common share. Because the conversion option is priced in U.S. dollars, relative to the Company’s functional currency, US GAAP requires the embedded conversion option to be bifurcated and accounted for as a stand-alone derivative instrument (the "Conversion Option Derivative"). The Conversion Option Derivative is recorded at fair value on the Company’s consolidated balance sheets and mark-to-market changes in fair value are recorded in earnings. The Convertible Notes were initially recorded at their face amount of $ 120.0 million less debt issuance costs of $ 5.2 million and the fair value of the Conversion Option Derivative, which was determined to be $ 49.1 million. The fair value of the Conversion Option Derivative liability was $ 49.1 million and $ 52.3 million as of the December 15, 2025 Convertible Notes’ issuance date and December 31, 2025, respectively, which resulted in a $ 3.2 million mark-to-market loss for the year ended December 31, 2025.

Inventory Derivative Obligation On November 20, 2024, we executed an agreement to borrow up to 250,000 pounds of U 3 O 8 from a counterparty. The agreement is for one year and calls for interest payments of 5.25 % per annum on the value of any uranium borrowed. In addition, there is a requirement to pay 1.5 % per annum interest on any pounds not borrowed. The uranium loan value and interest expense calculations are based on the current average spot price. At the end of each period, the loan is subject to mark-to-market adjustments to reflect the current loan valuation. In addition, the Company is required to post a minimum deposit of $ 15 per pound on any pounds borrowed. If the average uranium prices increase above certain thresholds, an additional $ 5 per pound will be deposited with the counterparty. Conversely, if the average uranium price declines below the thresholds, the Company can request a deposit refund of $ 5 per pound, subject to the minimum $ 15 per pound deposit. The uranium loan was originally due November 30, 2025, and was extended to November 30, 2026. On October 16, 2025, we executed a second agreement to borrow up to 150,000 pounds of U 3 O 8 from the same counterparty with similar provisions. The second agreement is due November 30, 2026. No uranium has been borrowed under the second agreement. On December 1, 2024, the Company exercised the option to borrow 250,000 pounds, which were subsequently sold into a uranium sales agreement, and posted the minimum $ 15 per pound deposit. The Company can return borrowed uranium at any time with 30 days ’ notice without penalty and with the right to reborrow the uranium before the termination of the loan. Upon return of borrowed uranium, the counterparty will refund the respective posted deposit to the Company. During 2024, the loan value was initially recorded at $ 77.13 per pound and was subsequently adjusted to $ 72.63 per pound resulting in a mark-to-market gain of $ 1.1 million in 2024. The loan value is recorded at $ 81.55 per pound as of December 31, 2025, which resulted in a $ 2.2 million mark-to-market loss for the year ended December 31, 2025.

As of December 31, 2025, 38,273,500 warrants to purchase 19,136,750 common shares were outstanding. As discussed in note 2, the Company’s functional currency is the Canadian dollar and because the warrants are priced in U.S. dollars, a derivative financial liability was created (the “Warrant Liability”). The Warrant Liability is recorded at fair value on the Company’s consolidated balance sheets and mark-to-market adjustments in fair value are recorded in earnings. Using Level 2 inputs of the fair value hierarchy under US GAAP, the liability created is measured and recorded at fair value, using the Black-Scholes model described below as there is no active market for the warrants.

The Option Plan was most recently approved by the shareholders on June 2, 2023. Eligible participants under the Option Plan include directors, officers, employees, and consultants of the Company. Under the terms of the Option Plan, grants of options will vest over a three-year period: one-third on the first anniversary, one-third on the second anniversary, and one-third on the third anniversary of the grant.

The total intrinsic value of options exercised was $ 2.0 million and $ 1.7 million for the years ended December 31, 2025 and 2024, respectively. We received $ 1.2 million and $ 1.3 million from options exercised in the years ended December 31, 2025 and 2024, respectively. Stock-based compensation expense from stock options was $ 1.1 million and $ 0.8 million for the years ended December 31, 2025 and 2024, respectively. The expense created an increase in our deferred tax assets of $ 0.1 million and $ 0.1 million as of December 31, 2025 and 2024, respectively. As of December 31, 2025, there was approximately $ 3.3 million unamortized stock-based compensation expense related to the Option Plan.

Operating Costs Operating expenses include exploration and evaluation expense, development expense, general and administration (“G&A”) expense, and mineral property write-offs. Exploration and evaluation expense consists of labor and the associated costs of the exploration and evaluation departments as well as land holding and exploration costs including drilling and analysis on properties which have not reached the permitting or operations stage. Development expense relates to properties that have reached the permitting or operations stage and include costs associated with exploring, delineating, and permitting a property. Once permitted, development expenses also include the costs associated with the construction and development of the permitted property that are otherwise not eligible to be capitalized. G&A expense relates to the administration, finance, investor relations, land, and legal functions, and consists principally of personnel, facility, and support costs. Operating costs consist of the following: ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ December 31, Operating Costs ​ 2025 ​ 2024 ​ ​ ​ ​ ​ Exploration and evaluation ​ 4,899 ​ 3,803 Development ​ 54,430 ​ 41,509 General and administration ​ 8,880 ​ 8,044 Accretion of asset retirement obligations ​ 1,245 ​ 760 ​ ​ 69,454 ​ 54,116 ​ ​ 23. Supplemental Information for Statement of Cash Flows Cash and cash equivalents, and restricted cash and cash equivalents within the consolidated statements of cash flows consists of the following: ​ ​ ​ ​ ​ ​ Cash and Cash Equivalents, and Restricted Cash and Cash Equivalents ​ December 31, 2025 ​ December 31, 2024 ​ ​ ​ ​ ​ Cash and cash equivalents ​ 123,863 ​ 76,055 Restricted cash and cash equivalents ​ 11,484 ​ 11,023 ​ ​ 135,347 ​ 87,078 ​ On December 1, 2024, the Company exercised an option to borrow 250,000 pounds, which were subsequently sold into a uranium sales agreement. The loan value was initially recorded at $ 77.13 per pound, which was the value applied to the cost of the sale (see note 15). The cost of sale on the borrowed inventory was a non-cash transaction. ​ ​ ​ ​ ​ ​ Non-cash Operating Activity ​ December 31, 2025 ​ December 31, 2024 ​ ​ ​ ​ ​ Drill rigs converted from capital assets to leases receivable ​ 1,620 ​ 1,331 Non-cash cost of sales on borrowed inventory ​ — ​ 19,282 ​ Estimated reclamation costs increased $ 6.4 million and $ 4.9 million in the years ended December 31, 2025 and 2024, respectively.

As discussed in note 13, interest expense recognized associated with the Convertible Notes’ debt discount amortization of $ 0.5 million is non-cash in nature. Further, $ 0.2 million of Convertible Notes’ accrued interest is non-cash in nature and included within accounts payable as of December 31, 2025. ​ ​ ​ ​ ​ ​ Cash and Non-cash Interest Expense ​ December 31, 2025 ​ December 31, 2024 ​ ​ ​ ​ ​ Cash interest expense ​ 1,244 ​ 304 Non-cash interest expense ​ 703 ​ 32 ​ ​ ​ ​ ​ ​ ​ 1,947 ​ 336 ​ Accounts payable included $ 4.6 million and $ 0.2 million in equipment and other purchases as of December 31, 2025 and 2024, respectively. As these did not affect cash balances at the respective dates, they have been adjusted on the consolidated statements of cash flows. 24. Income Taxes Income (loss) before income taxes on which the provision for income taxes was computed was as follows: ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, Income (Loss) before Income Tax Provision ​ 2025 ​ 2024 ​ ​ ​ ​ ​ Canada ​ ( 10,618 ) ​ 1,568 United States ​ ( 64,280 ) ​ ( 54,757 ) ​ ​ ( 74,898 ) ​ ( 53,189 ) ​ There was no federal or state income tax provision (benefit) in the years presented above. Deferred income taxes reflect the net tax effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and (b) operating losses and tax credit carryforwards. ​ F-36 Table of Contents Ur-Energy Inc. Notes to Consolidated Financial Statements December 31, 2025 (expressed in thousands of U.S. dollars, except share data, unless otherwise indicated) ​ ​ The tax effects of significant items comprising the Company’s deferred tax assets and liabilities are as follows: ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, Deferred Tax Assets ​ 2025 ​ 2024 ​ ​ ​ ​ ​ Deferred tax assets ​ ​ ​ ​ Cumulative Eligible Capital Deduction ​ 20 ​ 20 Share Issues Cost ​ 1,096 ​ 1,537 Fixed Asset ​ 9,837 ​ 7,571 Lease Liability ​ 1 ​ 2 Net Operating Loss ​ 70,336 ​ 60,235 ITC Credits ​ 247 ​ 235 Compensation Accruals ​ 174 ​ 145 Asset Retirement Obligation ​ 12,389 ​ 10,332 Equity Compensation ​ 925 ​ 822 Total deferred tax assets ​ 95,025 ​ 80,899 ​ ​ ​ ​ ​ Deferred tax liabilities ​ ​ ​ ​ Unrealized Gain/Loss ​ ( 1 ) ​ ( 1 ) ROU Asset ​ ( 1 ) ​ ( 2 ) Total Deferred tax liabilities ​ ( 2 ) ​ ( 3 ) ​ ​ ​ ​ ​ Valuation allowance ​ ( 95,023 ) ​ ( 80,896 ) ​ ​ ​ ​ ​ Net deferred taxes ​ — ​ — ​ ASC 740 requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income within the carryforward period. Because of the Company’s recent history of operating losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly, has recorded a valuation allowance. The valuation allowance increased by $ 14,127 and $ 18,808 during 2025 and 2024, respectively. Net operating losses and tax credit carryforwards as of December 31, 2025, are as follows: ​ ​ ​ ​ ​ ​ Income Tax Loss Carryforwards ​ Amount ​ Expiration Years ​ ​ ​ ​ ​ Net operating losses, Canada (CAD$) ​ 82,969 ​ 2026 - 2044 Net operating losses, federal (Pre January 1, 2018) ​ 79,699 ​ 2029 - 2035 Net operating losses, federal (Post December 31, 2017) ​ 145,257 ​ No expirations Net operating losses, state ​ 223,457 ​ Varies by state Tax Credits, Foreign (CAD$) ​ 339 ​ 2026 - 2029 ​ ​ F-37 Table of Contents Ur-Energy Inc. Notes to Consolidated Financial Statements December 31, 2025 (expressed in thousands of U.S. dollars, except share data, unless otherwise indicated) ​ ​ The effective tax rate of the Company’s provision (benefit) for income taxes differs from the federal statutory rate as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, Income Tax Rate Reconciliation ​ 2025 ​ 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ Canadian Statutory Rate ​ ( 11,235 ) ​ 15.0 % ​ ( 7,979 ) ​ 15.0 % Change in valuation allowance ​ 1,007 ​ ( 1.3 )% ​ 1,232 ​ ( 2.3 )% Nondeductible items ​ ​ ​ ​ ​ ​ ​ ​ Mark-to-Market Warrants ​ 560 ​ ( 0.8 )% ​ ( 819 ) ​ 1.5 % Other ​ 87 ​ ( 0.1 )% ​ 59 ​ ( 0.1 )% Other ​ ​ ​ ​ ​ ​ ​ ​ Share Issuance Costs ​ ( 60 ) ​ 0.1 % ​ ( 707 ) ​ 1.3 % Foreign tax effects ​ ​ ​ ​ ​ ​ ​ ​ United States ​ ​ ​ ​ ​ ​ ​ ​ Rate differential ​ ( 3,857 ) ​ 5.1 % ​ ( 3,285 ) ​ 6.2 % Stock compensation ​ ( 133 ) ​ 0.2 % ​ ( 109 ) ​ 0.2 % Nondeductible items and other ​ 23 ​ 0.0 % ​ 22 ​ 0.0 % Change in valuation allowance ​ 13,608 ​ ( 18.2 )% ​ 11,586 ​ ( 21.8 )% ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ — ​ 0.0 % ​ — ​ 0.0 % ​ The Company follows a comprehensive model for recognizing, measuring, presenting, and disclosing uncertain tax positions taken or expected to be taken on a tax return. Tax positions must initially be recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions must initially and subsequently be measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and relevant facts. The Company currently has no uncertain tax positions and is therefore not reflecting any adjustments for such in its deferred tax assets. The Company’s policy is to account for income tax related interest and penalties in income tax expense in the accompanying consolidated statements of operations and comprehensive loss. There have been no income tax related interest or penalties assessed or recorded in the years ended December 31, 2025 and 2024. Other comprehensive loss was not subject to income tax effects. ​ F-38 Table of Contents Ur-Energy Inc.

Financial instruments The Company’s financial instruments consist of cash and cash equivalents, trade receivables, lease receivables, restricted cash and cash equivalents, accounts payable and accrued liabilities, notes payable, the inventory derivative obligation, warrant liability, conversion option derivative, and capped call derivative. The Company is exposed to risks related to changes in interest rates and management of cash and cash equivalents. Credit risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, and restricted cash and cash equivalents. These assets include Canadian dollar and U.S. dollar denominated certificates of deposit, money market accounts, and demand deposits. These instruments are maintained at financial institutions in Canada and the U.S. Of the amount held on deposit, approximately $ 0.6 million is covered by the Canada Deposit Insurance Corporation, the Securities Investor Protection Corporation, or the U.S. Federal Deposit Insurance Corporation (“FDIC”), leaving approximately $ 134.7 million at risk on December 31, 2025, should the financial institutions with which these amounts are invested be rendered insolvent. The Company does not consider any of its financial assets to be impaired as of December 31, 2025. F-39 Table of Contents Ur-Energy Inc.
