As more fully described under Item 1. Business, in our Form 10-K Annual Report for Fiscal 2017, Uranium Energy Corp. was incorporated under the laws of the State of Nevada on May 16, 2003, and since 2004, we have been predominantly engaged in uranium mining and related activities, including exploration, pre-extraction, extraction and processing, on projects located in the United States and Paraguay. In November 2010, we commenced uranium extraction for the first time at the Palangana Mine utilizing ISR and processed those materials at the Hobson Processing Facility into drums of U₃O₈, our only sales product and source of revenue. We also hold uranium projects in various stages of exploration and pre-extraction in the States of Arizona, Colorado, New Mexico, Texas and Wyoming, in the Republic of Paraguay and in Canada. Since we completed the acquisition of the Alto Paraná Project located in the Republic of Paraguay in July 2017, we are also involved in mining and related activities, including exploration, pre-extraction, extraction and processing of titanium minerals.

As more fully described under "Liquidity and Capital Resources" of Item 2. Management's Discussion and Analysis of Financial Condition and Result of Operations, in our Form 10-Q Quarterly Report for the period ended January 31, 2018, we have a history of significant negative cash flow and net losses, with an accumulated deficit balance since inception of $236.2 million at January 31, 2018. Historically, we have been reliant primarily on equity financings from the sale of our common stock and, for Fiscal 2014 and Fiscal 2013, on debt financing in order to fund our operations. Although we generated revenues from sales of U₃O₈ during Fiscal 2015, Fiscal 2013 and Fiscal 2012 of $3.1 million, $9.0 million and $13.8 million, respectively, with no revenues from sales of U₃O₈ generated during the six months ended January 31, 2018, Fiscal 2017, Fiscal 2016, Fiscal 2014 or for any periods prior to Fiscal 2012, we have yet to achieve profitability or develop positive cash flow from our operations, and we do not expect to achieve profitability or develop positive cash flow from operations in the near term. As a result of our limited financial and operating history, including our significant negative cash flow and net losses to date, it may be difficult to evaluate our future performance.

At January 31, 2018, we had working capital of $15.1 million including cash and cash equivalents of $3.6 million and short-term investments of $12.2 million. As we do not expect to achieve and maintain profitability in the near term, our continuation as a going concern is dependent upon our ability to obtain adequate additional financing which we have successfully secured since inception, including those from asset divestitures. However, there is no assurance that we will be successful in securing any form of additional financing in the future and, therefore, substantial doubt exists as to whether our cash resources and/or working capital will be sufficient to enable our Company to continue our operations over the next twelve months from the date of this Registration Statement.

4

Our reliance on equity and debt financings is expected to continue for the foreseeable future, and their availability, whenever such additional financing is required, will be dependent on many factors beyond our control including, but not limited to, the market price of uranium, the continuing public support of nuclear power as a viable source of electrical generation, the volatility in the global financial markets affecting our stock price and the status of the worldwide economy, any one of which may cause significant challenges in our ability to access additional financing, including access to the equity and credit markets. We may also be required to seek other forms of financing, such as asset divestitures or joint venture arrangements, to continue advancing our uranium projects which would depend entirely on finding a suitable third party willing to enter into such an arrangement, typically involving an assignment of a percentage interest in the mineral project.

Our long-term success, including the recoverability of the carrying values of our assets and our ability to acquire additional uranium projects and continue with exploration and pre-extraction activities and mining activities on our existing uranium projects, will depend ultimately on our ability to achieve and maintain profitability and positive cash flow from our operations by establishing ore bodies that contain commercially recoverable uranium and to develop these into profitable mining activities. The economic viability of our mining activities, including the expected duration and profitability of the Palangana Mine and of any future satellite ISR mines, such as the Burke Hollow and Goliad Projects, located within the South Texas Uranium Belt, and the Reno Creek Project located in the Powder River Basin, Wyoming, and our projects in the Republic of Paraguay and in Canada, have many risks and uncertainties. These include, but are not limited to: (i) a significant, prolonged decrease in the market price of uranium and titanium minerals; (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 mineral extraction; (vi) significant delays, reductions or stoppages of uranium extraction activities; and (vi) the introduction of significantly more stringent regulatory laws and regulations. Our mining activities may change as a result of any one or more of these risks and uncertainties and there is no assurance that any ore body that we extract mineralized materials from will result in achieving and maintaining profitability and developing positive cash flow.

Our operations are capital intensive and future capital expenditures are expected to be substantial. We will require significant additional financing to fund our operations, including acquiring additional projects and continuing with our exploration and pre-extraction activities which include assaying, drilling, geological and geochemical analysis and mine construction costs. In the absence of such additional financing we would not be able to fund our operations or continue with our exploration and pre-extraction activities, which may result in delays, curtailment or abandonment of any one or all of our projects.

On February 9, 2016, we entered into the Second Amended Credit Agreement with our Lenders under which we had previously drawn down the maximum $20 million in principal. The Credit Facility requires monthly interest payments calculated at 8% per annum and other periodic fees, and principal repayments of $1.67 million per month over a twelve-month period commencing on February 1, 2019. Our ability to continue making these scheduled payments will be dependent on and may change as a result of our financial condition and operating results. Failure to make any one of these scheduled payments will put us in default with the Credit Facility which, if not addressed or waived, could require accelerated repayment of our indebtedness and/or enforcement by the Lenders against our assets. Enforcement against our assets would have a material adverse effect on our financial condition and operating results.

Furthermore, our Credit Facility includes restrictive covenants that, among other things, limit our ability to sell our assets or to incur additional indebtedness other than permitted indebtedness, which may restrict our ability to pursue certain business strategies from time to time. If we do not comply with these restrictive covenants, we could be in default which, if not addressed or waived, could require accelerated repayment of our indebtedness and/or enforcement by the Lenders against our assets.

5

Our uranium extraction and sales history is limited, with our uranium extraction to date originating from a single uranium mine. Our ability to continue generating revenue is subject to a number of factors, any one or more of which may adversely affect our financial condition and operating results.

We have a limited history of uranium extraction and generating revenue. In November 2010, we commenced uranium extraction at the Palangana Mine, which has been our sole source of U₃O₈ sold to generate the revenues during Fiscal 2015, Fiscal 2013 and Fiscal 2012 of $3.1 million, $9.0 million and $13.8 million, respectively, with no revenues from sales of U₃O₈ generated during the six months ended January 31, 2018, Fiscal 2017, Fiscal 2016, Fiscal 2014 or for any periods prior to Fiscal 2012.

During the six months ended January 31, 2018, we continued to operate the Palangana Mine at a reduced pace since implementing our strategic plan in September 2013 to align our operations to a weak uranium commodity market in a challenging post-Fukushima environment. This strategy has included the deferral of major pre-extraction expenditures and remaining in a state of operational readiness in anticipation of a recovery in uranium prices.  Our ability to continue generating revenue from the Palangana Mine is subject to a number of factors which 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. Furthermore, continued mining activities at the Palangana Mine will eventually deplete the Palangana Mine or cause such activities to become uneconomical, and if we are unable to directly acquire or develop existing uranium projects, such as our Burke Hollow and Goliad Projects, into additional uranium mines from which we can commence uranium extraction, it will negatively impact our ability to generate revenues. Any one or more of these occurrences may adversely affect our financial condition and operating results.

Exploration and pre-extraction programs and mining activities are inherently subject to numerous significant risks and uncertainties, with many beyond our control and including, but not limited to: (i) unanticipated ground and water conditions and adverse claims to water rights; (ii) unusual or unexpected geological formations; (iii) metallurgical and other processing problems; (iv) the occurrence of unusual weather or operating conditions and other force majeure events; (v) lower than expected ore grades; (vi) industrial accidents; (vii) delays in the receipt of or failure to receive necessary government permits; (viii) delays in transportation; (ix) availability of contractors and labor; (x) government permit restrictions and regulation restrictions; (xi) unavailability of materials and equipment; and (xii) the failure of equipment or processes to operate in accordance with specifications or expectations. These risks and uncertainties could result in: (i) delays, reductions or stoppages in our mining activities; (ii) increased capital and/or extraction costs; (iii) damage to, or destruction of, our mineral projects, extraction facilities or other properties; (iv) personal injuries; (v) environmental damage; (vi) monetary losses; and (vii) legal claims.

Success in mineral exploration is dependent on many factors, including, without limitation, the experience and capabilities of a company's management, the availability of geological expertise and the availability of sufficient funds to conduct the exploration program. Even if an exploration program is successful and commercially recoverable material is established, it may take a number of years from the initial phases of drilling and identification of the mineralization until extraction is possible, during which time the economic feasibility of extraction may change such that the material ceases to be economically recoverable. Exploration is frequently non-productive due, for example, to poor exploration results or the inability to establish ore bodies that contain commercially recoverable material, in which case the project may be abandoned and written-off. Furthermore, we will not be able to benefit from our exploration efforts and recover the expenditures that we incur on our exploration programs if we do not establish ore bodies that contain commercially recoverable material and develop these projects into profitable mining activities, and there is no assurance that we will be successful in doing so for any of our projects.

Whether an ore body contains commercially recoverable material depends on many factors including, without limitation: (i) the particular attributes, including material changes to those attributes, of the ore body such as size, grade, recovery rates and proximity to infrastructure; (ii) the market price of uranium, which may be volatile; and (iii) government regulations and regulatory requirements including, without limitation, those relating to environmental protection, permitting and land use, taxes, land tenure and transportation.

We have established the existence of mineralized materials for certain projects, including the Palangana Mine. We have not established proven or probable reserves, as defined by the SEC under Industry Guide 7, through the completion of a "final" or "bankable" feasibility study for any of our projects, including the Palangana Mine. Furthermore, we have no plans to establish proven or probable reserves for any of our projects for which we plan on utilizing ISR mining, such as the Palangana Mine. Since we commenced uranium extraction at the Palangana Mine without having established proven or probable reserves, there may be greater inherent uncertainty as to whether or not any mineralized material can be economically extracted as originally planned and anticipated. Any mineralized materials established or extracted from the Palangana Mine should not in any way be associated with having established or produced from proven or probable reserves.

Despite the fact that we commenced uranium extraction at the Palangana Mine in November 2010, we remain in the Exploration Stage as defined under Industry Guide 7, and will continue to remain in the Exploration Stage until such time proven or probable reserves have been established, which may never occur. We prepare our consolidated financial statements in accordance with United States generally accepted accounting principles ("U.S. GAAP") under which acquisition costs of mineral rights are initially capitalized as incurred while pre-production expenditures are expensed as incurred until such time we exit the Exploration Stage.  Expenditures relating to exploration activities are expensed as incurred and expenditures relating to pre-extraction activities are expensed as incurred until such time proven or probable reserves are established for that uranium project, after which subsequent expenditures relating to mine development activities for that particular project are capitalized as incurred.

We have neither established nor have any plans to establish proven or probable reserves for our uranium projects for which we plan on utilizing ISR mining, such as the Palangana Mine. Companies in the Production Stage as defined by the SEC under Industry Guide 7, having established proven and probable reserves and exited the Exploration Stage, typically capitalize expenditures relating to ongoing development activities, with corresponding depletion calculated over proven and probable reserves using the units-of-production method and allocated to future reporting periods to inventory and, as that inventory is sold, to cost of goods sold. As we are in the Exploration Stage, it has resulted in us reporting larger losses than if we had been in the Production Stage due to the expensing, instead of capitalization, of expenditures relating to ongoing mill and mine pre-extraction activities. Additionally, there would be no corresponding amortization allocated to our future reporting periods since those costs would have been expensed previously, resulting in both lower inventory costs and cost of goods sold and results of operations with higher gross profits and lower losses than if we had been in the Production Stage. Any capitalized costs, such as acquisition costs of mineral rights, are depleted over the estimated extraction life using the straight-line method. As a result, our consolidated financial statements may not be directly comparable to the financial statements of companies in the Production Stage.

We are responsible for certain remediation and decommissioning activities in the future primarily for our Hobson Processing Facility, Palangana Mine, Reno Creek Project and Alto Paraná Project and have recorded a liability of $3.9 million on our balance sheet at January 31, 2018, to recognize the present value of the estimated costs of such reclamation obligations.  Should the actual costs to fulfill these future reclamation obligations materially exceed these estimated costs, it may have an adverse effect on our financial condition and operating results, including not having the financial resources required to fulfill such obligations when required to do so.

7

During Fiscal 2015, we secured $5.6 million of surety bonds as an alternate source of financial assurance for the estimated costs of the reclamation obligations of our Hobson Processing Facility and Palangana Mine, of which we have $1.7 million funded and held as restricted cash for collateral purposes as required by the surety. We may be required at any time to fund the remaining $3.9 million or any portion thereof for a number of reasons including, but not limited to, the following: (i) the terms of the surety bonds are amended, such as an increase in collateral requirements; (ii) we are in default with the terms of the surety bonds; (iii) the surety bonds are no longer acceptable as an alternate source of financial assurance by the regulatory authorities; or (iv) the surety encounters financial difficulties. Should any one or more of these events occur in the future, we may not have the financial resources to fund the remaining amount or any portion thereof when required to do so.

In general, where coverage is available and not prohibitively expensive relative to the perceived risk, we will maintain insurance against such risk, subject to exclusions and limitations. We currently maintain insurance against certain risks including securities and general commercial liability claims and certain physical assets used in our operations, subject to exclusions and limitations, however, we do not maintain insurance to cover all of the potential risks and hazards associated with our operations.  We may be subject to liability for environmental, pollution or other hazards associated with our exploration, pre-extraction and extraction activities, which we may not be insured against, which may exceed the limits of our insurance coverage or which we may elect not to insure against because of high premiums or other reasons. Furthermore, we cannot provide assurance that any insurance coverage we currently have will continue to be available at reasonable premiums or that such insurance will adequately cover any resulting liability.

From time to time we examine opportunities to acquire additional mining assets and businesses. Any acquisition that we may choose to complete may be of a significant size, may change the scale of our business and operations, and may expose us to new geographic, political, operating, financial and geological risks. Our success in our acquisition activities depends on our ability to identify suitable acquisition candidates, negotiate acceptable terms for any such acquisition and integrate the acquired operations successfully with those of our Company. Any acquisitions would be accompanied by risks which could have a material adverse effect on our business. For example: (i) there may be a significant change in commodity prices after we have committed to complete the transaction and established the purchase price or exchange ratio; (ii) a material ore body may prove to be below expectations; (iii) we may have difficulty integrating and assimilating the operations and personnel of any acquired companies, realizing anticipated synergies and maximizing the financial and strategic position of the combined enterprise, and maintaining uniform standards, policies and controls across the organization; (iv) the integration of the acquired business or assets may disrupt our ongoing business and our relationships with employees, customers, suppliers and contractors; and (v) the acquired business or assets may have unknown liabilities which may be significant. In the event that we choose to raise debt capital to finance any such acquisition, our leverage will be increased. If we choose to use equity as consideration for such acquisition, existing shareholders may suffer dilution. Alternatively, we may choose to finance any such acquisition with our existing resources. There can be no assurance that we would be successful in overcoming these risks or any other problems encountered in connection with such acquisitions.

Uranium exploration and pre-extraction programs and mining activities are subject to numerous stringent laws, regulations and standards at the federal, state and local levels governing permitting, pre-extraction, extraction, exports, taxes, labor standards, occupational health, waste disposal, protection and reclamation of the environment, protection of endangered and protected species, mine safety, hazardous substances and other matters. Our compliance with these requirements requires significant financial and personnel resources.

The laws, regulations, policies or current administrative practices of any government body, organization or regulatory agency in the United States or any other applicable jurisdiction may change or be applied or interpreted in a manner which may also have a material adverse effect on our operations. The actions, policies or regulations, or changes thereto, of any government body or regulatory agency or special interest group may also have a material adverse effect on our operations.

8

Uranium exploration and pre-extraction programs and mining activities are subject to stringent environmental protection laws and regulations at the federal, state, and local levels. These laws and regulations include permitting and reclamation requirements, regulate emissions, water storage and discharges and disposal of hazardous wastes. Uranium mining activities are also subject to laws and regulations which seek to maintain health and safety standards by regulating the design and use of mining methods. Various permits from governmental and regulatory bodies are required for mining to commence or continue, and no assurance can be provided that required permits will be received in a timely manner.

Our compliance costs, including the posting of surety bonds associated with environmental protection laws and regulations and health and safety standards, have been significant to date, and are expected to increase in scale and scope as we expand our operations in the future. Furthermore, environmental protection laws and regulations may become more stringent in the future, and compliance with such changes may require capital outlays in excess of those anticipated or cause substantial delays, which would have a material adverse effect on our operations.

To the best of our knowledge, our operations are in compliance, in all material respects, with all applicable laws, regulations and standards. If we become subject to liability for any violations we may not be able or may elect not to insure against such risk due to high insurance premiums or other reasons. Where coverage is available and not prohibitively expensive relative to the perceived risk, we will maintain insurance against such risk, subject to exclusions and limitations. However, we cannot provide any assurance that such insurance will continue to be available at reasonable premiums or that such insurance will be adequate to cover any resulting liability.

We may not be able to obtain, maintain or amend rights, authorizations, licenses, permits or consents required for our operations.

Our exploration and mining activities are dependent upon the grant of appropriate rights, authorizations, licences, permits and consents, as well as continuation and amendment of these rights, authorizations, licences, permits and consents already granted, which may be granted for a defined period of time, or may not be granted or may be withdrawn or made subject to limitations. There can be no assurance that all necessary rights, authorizations, licences, permits and consents will be granted to us, or that authorizations, licences, permits and consents already granted will not be withdrawn or made subject to limitations.

The marketability of uranium concentrates extracted by us will be affected by numerous factors beyond our control. These factors include macroeconomic factors, fluctuations in the market price of uranium, governmental regulations, land tenure and use, regulations concerning the importing and exporting of uranium and environmental protection regulations. The future effects of these factors cannot be accurately predicted, but any one or a combination of these factors may result in our inability to receive an adequate return on our invested capital.

Titanium is used in many "quality of life" products for which demand historically has been linked to global, regional and local GDP and discretionary spending, which can be negatively impacted by regional and world events or economic conditions. Such events are likely to cause a decrease in demand for products and, as a result, may have an adverse effect on our results of operations and financial condition. The timing and extent of any changes to currently prevailing market conditions is uncertain, and supply and demand may be unbalanced at any time. Uncertain economic conditions and market instability make it particularly difficult for us to forecast demand trends. As a consequence, we may not be able to accurately predict future economic conditions or the effect of such conditions on our financial condition or results of operations. We can give no assurances as to the timing, extent or duration of the current or future economic cycles impacting the industries in which we operate.

9

Historically, the market for large volume titanium applications, including coatings, paper and plastics, has experienced alternating periods of tight supply, causing prices and margins to increase, followed by periods of lower capacity utilization resulting in declining prices and margins. The volatility this market experiences occurs as a result of significant changes in the demand for products as a consequence of global economic activity and changes in customers' requirements. The supply-demand balance is also impacted by capacity additions or reductions that result in changes of utilization rates. In addition, titanium margins are impacted by significant changes in major input costs such as energy and feedstock. Demand for titanium depends in part on the housing and construction industries. These industries are cyclical in nature and have historically been impacted by downturns in the economy. In addition, pricing may affect customer inventory levels as customers may from time to time accelerate purchases of titanium in advance of anticipated price increases or defer purchases of titanium in advance of anticipated price decreases. The cyclicality and volatility of the titanium industry results in significant fluctuations in profits and cash flow from period to period and over the business cycle.

The uranium industry is highly competitive and our competition includes larger, more established companies with longer operating histories that not only explore for and produce uranium, but also market uranium and other products on a regional, national or worldwide basis. Due to their greater financial and technical resources we may not be able to acquire additional uranium projects in a competitive bidding process involving such companies. Additionally, these larger companies have greater resources to continue with their operations during periods of depressed market conditions.

The titanium industry is concentrated and highly competitive and we may not be able to compete effectively with our competitors that have greater financial resources or those that are vertically integrated, which could have a material adverse effect on our business, results of operations and financial condition.

The global titanium market is highly competitive, with the top six producers accounting for approximately 60% of the world's production capacity. Competition is based on a number of factors, such as price, product quality and service. Competition is based on a number of factors, such as price, product quality and service. Among our competitors are companies that are vertically-integrated (those that have their own raw material resources). Changes in the competitive landscape could make it difficult for us to retain our competitive position in various products and markets throughout the world. Our competitors with their own raw material resources may have a competitive advantage during periods of higher raw material prices. In addition, some of the companies with whom we compete may be able to produce products more economically than we can. Furthermore, some of our competitors have greater financial resources, which may enable them to invest significant capital into their businesses, including expenditures for research and development.

We hold certain mineral rights located in Paraguay through Piedra Rica Mining S.A., Transandes Paraguay S.A., Trier S.A. and Metalicos Y No Metalicos S.R.L, which are incorporated in Paraguay. Operations in foreign jurisdictions outside of the United States and Canada, especially in developing countries, may be subject to additional risks as they may have different political, regulatory, taxation, economic and cultural environments that may adversely affect the value or continued viability of our rights. These additional risks include, but are not limited to: (i) changes in governments or senior government officials; (ii) changes to existing laws or policies on foreign investments, environmental protection, mining and ownership of mineral interests; (iii) renegotiation, cancellation, expropriation and nationalization of existing permits or contracts; (iv) foreign currency controls and fluctuations; and (v) civil disturbances, terrorism and war.

In the event of a dispute arising at our foreign operations in Paraguay, we may be subject to the exclusive jurisdiction of foreign courts or may not be successful in subjecting foreign persons to the jurisdiction of the courts in the United States or Canada. We may also be hindered or prevented from enforcing our rights with respect to a government entity or instrumentality because of the doctrine of sovereign immunity. Any adverse or arbitrary decision of a foreign court may have a material and adverse impact on our business, prospects, financial condition and results of operations.

Although we have taken reasonable measures to ensure proper title to our interests in mineral properties and other assets, there is no guarantee that the title to any of such interests will not be challenged. No assurance can be given that we will be able to secure the grant or the renewal of existing mineral rights and tenures on terms satisfactory to us, or that governments in the jurisdictions in which we operate will not revoke or significantly alter such rights or tenures or that such rights or tenures will not be challenged or impugned by third parties, including local governments, aboriginal peoples or other claimants. The Company has had recent communications and filings with the Ministry of Public Works and Communications ("MOPC"), the mining regulator in Paraguay, whereby the MOPC is taking the position that certain concessions forming part of the Company's Yuty and Alto Parana projects are not eligible for extension as to exploration or continuation to exploitation in their current stages. While the Company remains fully committed to its development path forward in Paraguay, it now caused its legal counsel to file an appeal with the Administrative Courts in Paraguay to reverse the MOPC's position in order to protect the Company's continuing rights in those concessions. In the interim the Company also continues to pay all required maintenance fees and otherwise conducts its business in a manner to comply with all applicable mining laws in Paraguay. Our mineral properties may be subject to prior unregistered agreements, transfers or claims, and title may be affected by, among other things, undetected defects. A successful challenge to the precise area and location of our claims could result in us being unable to operate on our properties as permitted or being unable to enforce our rights with respect to our properties.

Due to the nature of our business, we may be subject to numerous regulatory investigations, securities claims, civil claims, lawsuits and other proceedings in the ordinary course of our business including those described under Item 1. Legal Proceedings in our Form 10-Q Quarterly Report for the period ended January 31, 2018. With respect to the Westminster Securities Corporation claim, the plaintiffs filed an appeal on March 22, 2018 to the District Court's order of dismissal, and subsequently the Company and the plaintiffs agreed to the dismissal of the appeal with prejudice effective April 18, 2018. The outcome of the other lawsuits is uncertain and subject to inherent uncertainties, and the actual costs to be incurred will depend upon many unknown factors. We may be forced to expend significant resources in the defense of these suits, and we may not prevail. Defending against these and other lawsuits in the future may not only require us to incur significant legal fees and expenses, but may become time-consuming for us and detract from our ability to fully focus our internal resources on our business activities. The results of any legal proceeding cannot be predicted with certainty due to the uncertainty inherent in litigation, the difficulty of predicting decisions of regulators, judges and juries and the possibility that decisions may be reversed on appeal. There can be no assurances that these matters will not have a material adverse effect on our business, financial position or operating results.

Our success is dependent on the efforts, abilities and continued service of certain senior officers and key employees and consultants. A number of our key employees and consultants have significant experience in the uranium industry. A loss of service from any one of these individuals may adversely affect our operations, and we may have difficulty or may not be able to locate and hire a suitable replacement.

The majority of our directors and officers are involved in other business ventures including similar capacities with other private or publicly-traded companies. Such individuals may have significant responsibilities to these other business ventures, including consulting relationships, which may require significant amounts of their available time. Conflicts of interest may include decisions on how much time to devote to our business affairs and what business opportunities should be presented to us. Our Code of Business Conduct for Directors, Officers and Employees provides for guidance on conflicts of interest.

11

The laws of the State of Nevada provide that our directors and officers will not be liable to us or to our stockholders for monetary damages for all but certain types of conduct as directors and officers. Our Bylaws provide for broad indemnification powers to all persons against all damages incurred in connection with our business to the fullest extent provided or allowed by law. These indemnification provisions may require us to use our limited assets to defend our directors and officers against claims, and may have the effect of preventing stockholders from recovering damages against our directors and officers caused by their negligence, poor judgment or other circumstances.

Several of our directors and officers are nationals and/or residents of countries other than the United States, and all or a substantial portion of such persons' assets are located outside of the United States. As a result, it may be difficult for investors to effect service of process on such directors and officers, or enforce within the United States any judgments obtained against such directors and officers, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state thereof. Consequently, stockholders may be effectively prevented from pursuing remedies against such directors and officers under United States federal securities laws. In addition, stockholders may not be able to commence an action in a Canadian court predicated upon the civil liability provisions under United States federal securities laws. The foregoing risks also apply to those experts identified in this document that are not residents of the United States.

Management's evaluation on the effectiveness of disclosure controls and procedures is designed to ensure that information required for disclosure in our public filings is recorded, processed, summarized and reported on a timely basis to our senior management, as appropriate, to allow timely decisions regarding required disclosure. Management's report on internal control over financial reporting is designed to provide reasonable assurance that transactions are properly authorized, assets are safeguarded against unauthorized or improper use and transactions are properly recorded and reported. However, any system of controls, no matter how well designed and operated, is based in part upon certain assumptions designed to obtain reasonable, and not absolute, assurance as to its reliability and effectiveness. Any failure to maintain effective disclosure controls and procedures in the future may result in our inability to continue meeting our reporting obligations in a timely manner, qualified audit opinions or restatements of our financial reports, any one of which may affect the market price for our common stock and our ability to access the capital markets.

On September 28, 2007, our common stock commenced trading on the NYSE American (formerly known as the American Stock Exchange, the NYSE Amex Equities Exchange and the NYSE MKT) and prior to that, traded on the OTC Bulletin Board.

The global markets have experienced significant and increased volatility in the past, and have been impacted by the effects of mass sub-prime mortgage defaults and liquidity problems of the asset-backed commercial paper market, resulting in a number of large financial institutions requiring government bailouts or filing for bankruptcy. The effects of these past events and any similar events in the future may continue to or further affect the global markets, which may directly affect the market price of our common stock and our accessibility for additional financing. Although this volatility may be unrelated to specific company performance, it can have an adverse effect on the market price of our shares which, historically, has fluctuated significantly and may continue to do so in the future.

In addition to the volatility associated with general economic trends and market conditions, the market price of our common stock could decline significantly due to the impact of any one or more events, including, but not limited to, the following: (i) volatility in the uranium market; (ii) occurrence of a major nuclear incident such as the events in Fukushima in March 2011; (iii) changes in the outlook for the nuclear power and uranium industries; (iv) failure to meet market expectations on our exploration, pre-extraction or extraction activities, including abandonment of key uranium projects; (v) sales of a large number of our shares held by certain stockholders including institutions and insiders; (vi) downward revisions to previous estimates on us by analysts; (vii) removal from market indices; (viii) legal claims brought forth against us; and (ix) introduction of technological innovations by competitors or in competing technologies.

Historically, we have relied on equity financing and, more recently, on debt financing, as primary sources of financing. A prolonged decline in the market price of our common stock or a reduction in our accessibility to the global markets may result in our inability to secure additional financing which would have an adverse effect on our operations.

We are authorized to issue 750,000,000 shares of common stock of which 160,392,106 shares were issued and outstanding as of June 6, 2018. Future issuances for financings, mergers and acquisitions, exercise of stock options and share purchase warrants and for other reasons may result in significant dilution to and be issued at prices substantially below the price paid for our shares held by our existing stockholders. Significant dilution would reduce the proportionate ownership and voting power held by our existing stockholders, and may result in a decrease in the market price of our shares.

We filed the 2014 Shelf which was declared effective on January 10, 2014, providing for the public offer and sale of certain securities of the Company from time to time, at our discretion, up to an aggregate offering amount of $100 million. We filed the 2017 Shelf, which was declared effective on March 10, 2017, and, as a result, it replaced the 2014 Shelf which was then deemed terminated. The 2017 Shelf provides for the public offer and sale of certain securities of our Company from time to time, at our discretion, up to an aggregate offering amount of $100 million, of which a total of $33.7 million has been utilized through public offerings as of January 31, 2018.

Our common stock is currently listed on the NYSE American.  In order to maintain this listing, we must maintain certain share prices, financial and share distribution targets, including maintaining a minimum amount of shareholders' equity and a minimum number of public shareholders.  In addition to these objective standards, the NYSE American may delist the securities of any issuer: (i) if, in its opinion, the issuer's financial condition and/or operating results appear unsatisfactory; (ii) if it appears that the extent of public distribution or the aggregate market value of the security has become so reduced as to make continued listing on the NYSE American inadvisable; (iii) if the issuer sells or disposes of principal operating assets or ceases to be an operating company; (iv) if an issuer fails to comply with the NYSE American's listing requirements; (v) if an issuer's common stock sells at what the NYSE American considers a "low selling price" and the issuer fails to correct this via a reverse split of shares after notification by the NYSE American; or (vi) if any other event occurs or any condition exists which makes continued listing on the NYSE American, in its opinion, inadvisable.

If the NYSE American delists our common stock, investors may face material adverse consequences, including, but not limited to, a lack of trading market for our securities, reduced liquidity, decreased analyst coverage of our securities and an inability for us to obtain additional financing to fund our operations.

This prospectus, including the documents that are and will be incorporated by reference into this prospectus, include statements and information about our strategy, objectives, plans and expectations for the future that are not statements or information of historical fact. These statements and information are considered to be forward-looking statements, or forward-looking information, within the meaning of and under the protection provided by the safe harbor provision for forward-looking statements as contained in the Private Securities Litigation Reform Act of 1995 and similar Canadian securities laws.

We will not receive any of the proceeds from the sale of 1,691,215 previously-issued shares of common stock by the Selling Securityholders pursuant to this prospectus.

The Selling Securityholders may sell all or a portion of the shares of common stock beneficially owned by them from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of common stock are sold through underwriters or broker-dealers, the Selling Securityholders will be responsible for underwriting discounts or commissions or agent's commissions. The shares of common stock may be sold on the NYSE American, any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale, or in transactions otherwise than on these exchanges or systems and in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions.

The Selling Securityholders, Uranerz Energy Corporation and Haywood Securities Inc. are offering, from time to time, up to an aggregate of 1,691,215 shares of common stock under this prospectus.

On November 1, 2017, we entered into a purchase agreement (the "Purchase Agreement") with Uranerz Energy Corporation ("Uranerz"), a Nevada corporation and a wholly-owned subsidiary of Energy Fuels Inc., to acquire 100% of Uranerz's North Reno Creek project located immediately adjacent to and within the Company's existing Reno Creek Project permitting boundary in the Powder River Basin, Wyoming, comprised of unpatented mining claims and mining leases, mining agreements and surface use and damage agreements (the "Mining Rights"), including, but not limited to, data and property documentation relating to the Mining Rights or the lands subject to the Mining Rights and water rights as described in the mining leases (collectively, the "Purchased Assets"), free and clear of all Encumbrances other than Permitted Encumbrances as such terms are defined in the Purchase Agreement. On February 15, 2018 and on March 9, 2018, we entered into amending agreements to the Purchase Agreement (the "Amendments") with Uranerz whereby the parties agreed to extend the closing date to allow time for Uranerz to obtain the required consents and releases to allow for closing.

Pursuant to the Purchase Agreement as partial consideration for the Purchased Assets, we issued 1,625,531 restricted shares of common stock to Uranerz as more particularly set forth in our Form 8-K filed with the SEC on May 4, 2018.

On May 8, 2017, we entered into a financial advisor letter agreement (the "Financial Advisory Agreement") with Haywood Securities Inc. ("Haywood"), which was amended on October 11, 2017, pursuant to which Haywood provided financial advisory services to us with respect to the Purchase Agreement. As consideration for Haywood's financial advisory services related to the Purchase Agreement, on May 1, 2018, we issued 65,684 restricted shares of common stock to Haywood pursuant to the terms of the Financial Advisory Agreement.

We agreed to file the registration statement of which this prospectus forms a part with the SEC in accordance with the requirements of the Securities Act in order to register such 1,691,215 shares of common stock for resale by the Selling Securityholders.

The securities issued with respect to the Purchase Agreement were issued in reliance on Rule 506(b) of Regulation D of the Securities Act based on representations and warranties contained in the Purchase Agreement. The securities issued with respect to the Financial Advisory Agreement were issued in reliance on Rule 903 of Regulation S of the Securities Act as the securities were issued to a person who was not a "U.S. person", within the meaning of Regulation S, and who was otherwise outside of the United States.

The following table sets forth information as of June 6, 2018 regarding the ownership of the shares of common stock to be sold by the Selling Securityholders.

Information with respect to "Number of shares owned prior to this offering" includes shares issuable upon exercise of warrants, if applicable, held by the Selling Securityholders and other shares held of record by the Selling Securityholders. The "Number of shares being offered" consists of the 1,691,215 shares which may be resold by the Selling Securityholders pursuant to this prospectus.

Information with respect to "Number of shares to be owned upon completion of this offering" assumes the sale of all of the shares being offered by this prospectus and no other purchases or sales of our common stock by the Selling Securityholders.

Except as described below and to our knowledge, the named Selling Securityholders own and have sole voting and investment power over all shares or rights to these shares. Except for their ownership of common stock described below, none of the Selling Securityholders had or have any material relationship with us. The Selling Securityholders may have sold or transferred, in transactions exempt from the registration requirements of the Securities Act, some or all of the common stock held by them since the date as of which information is presented below.

The applicable percentages of beneficial ownership are based on an aggregate of 160,392,106 shares of our common stock issued and outstanding on June 6, 2018, adjusted as may be required by rules promulgated by the SEC.

16

(1)       Beneficial ownership calculation under Rule 13d-3 of the Securities Exchange Act of 1934, as amended. Under Rule 13d-3, a beneficial owner of a security includes any person who, directly or indirectly, through any contract, arrangement, understanding, relationship, or otherwise has or shares: (i) voting power, which includes the power to vote, or to direct the voting of shares; and (ii) investment power, which includes the power to dispose or direct the disposition of shares. Certain shares may be deemed to be beneficially owned by more than one person (if, for example, persons share the power to vote or the power to dispose of the shares). In addition, shares are deemed to be beneficially owned by a person if the person has the right to acquire the shares (for example, upon exercise of an option) within 60 days of the date as of which the information is provided. In computing the percentage ownership of any person, the amount of shares outstanding is deemed to include the amount of shares beneficially owned by such person (and only such person) by reason of these acquisition rights.

(2)       The "Number of shares being offered" for each Selling Securityholder consists of the shares which are being registered pursuant to the registration statement of which this prospectus forms a part, that is, the 1,625,531 shares of common stock issued on May 1, 2018 pursuant to the Purchase Agreement, as amended, and the 65,684 shares of common stock issued on May 1, 2018 pursuant to the Financial Advisory Agreement, as amended.

(3)       Assumes that the Selling Securityholders sell all of the shares which are being registered under the registration statement of which this prospectus forms a part.

(4)       Based on 160,392,106 shares of our common stock issued and outstanding as of June 6, 2018.

(5)       Uranerz Energy Corporation is a wholly owned subsidiary of Energy Fuels Inc. Mr. Mark S. Chalmers, President and CEO of both Uranerz Energy Corporation and Energy Fuels Inc. has voting and dispositive power over these shares.

(6)       This figure consists of 1,625,531 shares of common stock only.

(7)       Each of John Tognetti, the Chairman of Haywood Securities Inc. ("Haywood"), David Lyall, the Vice Chairman of Haywood, Robert Blanchard, the CEO of Haywood and Peter Virvilis, the CFO of Haywood, have voting and dispositive power over these shares.

(8)       This figure consists of 65,684 shares of common stock only.

The Selling Securityholders may sell all or a portion of the shares of common stock beneficially owned by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of common stock are sold through underwriters or broker-dealers, the Selling Securityholders will be responsible for underwriting discounts or commissions or agent's commissions. The shares of common stock may be sold on the NYSE American, any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale, or in transactions otherwise than on these exchanges or systems and in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions.

The shares may be sold by means of one or more of the following methods:

17

1. a block trade in which the broker-dealer so engaged will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;
2. purchases by a broker-dealer as principal and resale by that broker-dealer for its account pursuant to this prospectus;
3. ordinary brokerage transactions in which the broker solicits purchasers;
4. through options, swaps or derivative;
5. privately negotiated transactions; or
6. in a combination of any of the above methods.

The Selling Securityholders may sell their shares directly to purchasers or may use brokers, dealers, underwriters or agents to sell their shares. Brokers or dealers engaged by the Selling Securityholders may arrange for other brokers or dealers to participate. Brokers or dealers may receive commissions, discounts or concessions from the Selling Securityholders, or, if any such broker-dealer acts as agent for the purchaser of shares, from the purchaser in amounts to be negotiated immediately prior to the sale. The compensation received by brokers or dealers may, but is not expected to, exceed that which is customary for the types of transactions involved. Broker-dealers may agree with a Selling Securityholder to sell a specified number of shares at a stipulated price per share, and, to the extent the broker-dealer is unable to do so acting as agent for a Selling Securityholder, to purchase as principal any unsold shares at the price required to fulfill the broker-dealer commitment to the Selling Securityholder. Broker-dealers who acquire shares as principal may thereafter resell the shares from time to time in transactions, which may involve block transactions and sales to and through other broker-dealers, including transactions of the nature described above, in the over-the-counter market or otherwise at prices and on terms then prevailing at the time of sale, at prices then related to the then-current market price or in negotiated transactions. In connection with resales of the shares, broker-dealers may pay to commissions or receive from commissions the purchasers of shares as described above.

If our Selling Securityholders enter into arrangements with brokers or dealers, as described above, we are obligated to file a post-effective amendment to the registration statement of which this prospectus forms a part, disclosing such arrangements, including the names of any broker dealers acting as underwriters.

The Selling Securityholders and any broker-dealers or agents that participate with the Selling Securityholders in the sale of the shares may be deemed to be "underwriters" within the meaning of the Securities Act. In that event, any commissions received by broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

Pursuant to the Purchase Agreement, Uranerz agrees that it cannot sell on any single trading day any shares covered by this prospectus representing more than ten percent (10%) of the average volume of UEC's common shares on the NYSE American measured over the five-day period immediately preceding the date on which Uranerz proposes to make such sale.

Any shares of common stock covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act, may be sold under Rule 144 rather than pursuant to this prospectus.

We have advised the Selling Securityholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the Selling Securityholders and their affiliates. Regulation M under the Exchange Act prohibits, with certain exceptions, participants in a distribution from bidding for, or purchasing for an account in which the participant has a beneficial interest, any of the securities that are the subject of the distribution. Accordingly, the Selling Securityholder is not permitted to cover short sales by purchasing shares while the distribution is taking place. Regulation M also governs bids and purchases made in order to stabilize the price of a security in connection with a distribution of the security. In addition, we will make copies of this prospectus available to the Selling Securityholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act.

18

Under the securities laws of some states, the shares may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares may not be sold unless the shares have been registered or qualified for sale in the state or an exemption from registration or qualification is available and is complied with.

We are bearing all costs relating to the registration of the common stock. The Selling Securityholders, however, will pay any commissions or other fees payable to brokers or dealers in connection with any sale of the common stock.

Our authorized capital stock consists of 750,000,000 shares of common stock with a par value of $0.001 per share. As of June 6, 2018 there were 160,392,106 shares of our common stock issued and outstanding.

Upon liquidation, dissolution or winding up of our company, the holders of common stock are entitled to share ratably in all net assets available for distribution to common stockholders after payment to secured convertible promissory note holders and creditors. The common stock is not convertible or redeemable and has no pre-emptive, subscription or conversion rights. Each outstanding share of common stock is entitled to one vote on all matters submitted to a vote of stockholders. There are no cumulative voting rights. The holders of outstanding shares of common stock are entitled to receive dividends out of assets legally available therefore at such times and in such amounts as our Board of Directors may from time to time determine. In the event of a merger or consolidation all holders of common stock will be entitled to receive the same per share consideration.
