NYSE American: URG • TSX: URE

August 2023

This presentation contains "forward-looking statements," within the meaning of applicable securities laws, regarding events or conditions that may occur in the future. Such statements include without limitation the Company's ability to timely and cost effectively ramp up at Lost Creek as planned, including maintaining experienced operational staff and hiring additional staff; the continued technical and economic viability of Lost Creek and whether the return to commercial operations is a return to low operational costs; whether and for how long Lost Creek will account for nearly all US uranium production; ability to secure additional uranium sales agreements; ability to further expand resources at the Lost Creek Property; the further exploration, development and permitting of Company projects, including in the Great Divide Basin and Shirley Basin; the technical and economic viability of Shirley Basin (including the estimated time for construction); the viability of ongoing R&D efforts, including the timing and cost to implement, permit and operate one or more of them; whether global support for nuclear energy development will continue and be sustained and the effects on the market; the effects of geopolitical events, including the Ukraine war; the long-term effects on the uranium market of supply and demand projections, including continuing acceptance of nuclear as integral to climate change initiatives; level of risks attendant to foreign uranium production held by non-public companies and the significance of investment in uranium and nuclear industry companies; and whether various prospective market catalysts including government support and possible legislation will occur and/or the effect(s) each may have on the market in the longer term. These statements 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. Numerous factors could cause actual events to differ materially from those in the forward-looking statements. Factors that could cause such differences, without limiting the generality of the following, include: risks inherent in exploration activities; volatility and sensitivity to market prices for uranium; volatility and sensitivity to capital market fluctuations; the impact of competition in the uranium sector; the ability to raise funds through private or public equity financings; imprecision in resource and reserve estimates; environmental and safety risks including increased regulatory burdens; unexpected geological or hydrological conditions; a possible deterioration in support for nuclear energy; changes in government regulations and policies, including trade laws and policies; demand for nuclear power; weather and other natural phenomena; delays in obtaining or failures to obtain required governmental, environmental or other project approvals; and other exploration, development, operating, financial market and regulatory risks. Although Ur-Energy Inc. believes the assumptions inherent in the forward-looking statements are reasonable, undue reliance should not be placed on these statements, which only apply as of the date of this presentation. Ur-Energy Inc. disclaims any intention or obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

Cautionary Note Regarding Projections: Similarly, this presentation also may contain projections relating to an extended future period and, accordingly, the estimates and assumptions underlying the projections are inherently highly uncertain, based on events that have not taken place, and are subject to significant economic, financial, regulatory, competitive and other uncertainties and contingencies beyond the control of Ur-Energy Inc. Further, given the nature of the Company's business and industry that is subject to numerous significant risk factors, there can be no assurance that the projections can be or will be realized. It is probable that the actual results and outcomes will differ, possibly materially, from those projected.

The attention of investors is drawn to the Risk Factors set out in the Company's Annual Report on Form 10-K, filed March 6, 2023, which is filed with the U.S. Securities and Exchange Commission on EDGAR (http://www.sec.gov/edgar.shtml) and the regulators in Canada on SEDAR (www.sedar.com).

Cautionary Note Concerning Estimates of Mineral Resources: Mineral resources that are not mineral reserves do not have demonstrated economic viability. Our mineral resource estimates, and the related economic analyses, are preliminary in nature and, in the case of the Lost Creek Report, include inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. The estimated mineral recovery used in our Technical Report Summaries is based on recovery data from wellfield operations to date at Lost Creek in the case of the Lost Creek Report, and Company personnel and industry experience at similar facilities in the case of the Shirley Basin Report. There can be no assurance that recovery at this level will be achieved.
