BUSINESS OVERVIEW

NexGen is a British Columbia corporation with a focus on developing into production the 100% owned Rook I Project (“Rook I Project” or the “Project”) located in the southwestern Athabasca Basin of Saskatchewan, Canada. NexGen has a highly experienced team of uranium industry professionals with a successful track record in the discovery of uranium deposits and in the development of projects from discovery to production. NexGen also owns a portfolio of highly prospective exploration uranium properties in the southwestern Athabasca Basin of Saskatchewan, Canada.

The Rook I Project is the location of the Company’s Arrow Deposit discovery in February 2014. The Arrow Deposit has measured and indicated Mineral Resources totalling 3.75 million tonnes (“Mt”) grading 3.10% U₃O₈ containing 257 million (“M”) lbs U₃O₈. The Probable Mineral Reserves were estimated at 240 M lbs U₃O₈ contained in 4.6Mt grading 2.37% U₃O₈. See “Feasibility Study” below.

The Company has also intersected numerous other mineralized zones on trend from Arrow along the Patterson Corridor on Rook I which are subject to further exploration before economic potential can be assessed. The Rook I Project consists of thirty-two (32) contiguous mineral claims totaling 35,065 hectares.

The Company is listed on the Toronto Stock Exchange (the “TSX”) and the New York Stock Exchange (the “NYSE”) under the symbol “NXE”, and on the ASX under the symbol “NXG”.

The Company currently holds 50.1% of the outstanding common shares of IsoEnergy.

6. Special waste in material between 0.03% and 0.26% U₃O₈ that must be extracted to access mining areas. 0.03% U₃O₈ is the limit for what is considered benign waste and material that must be treated and stockpiled in an engineered facility.

7. Mineral Reserves are estimated using a long-term metal price of US$50 per pound U₃O₈, and a 0.75 US$/C$ exchange rate (C$1.00 = US$0.75). The cost to ship the yellow cake product to a refinery is considered to be included in the metal price.

8. A minimum mining width of 3.0 m was applied for all long hole stopes.

9. Mineral Reserves are estimated using a combined underground mining recovery of 95.5% and total dilution (planned and unplanned) of 33.8%.

10. The density varies according to the U₃O₈ grade in the block model. Waste density is 2.464 t/m³.

11. Numbers may not add due to rounding.

Economic Results

The Rook I FS Technical Report was based on a uranium price estimate of US$50/lb U₃O₈ per pound, net of yellow cake transportation fees and a fixed USD:CAD conversion rate of 0.75 (the “Base Case”).

The economic analysis is based on the timing of a final investment decision (“FID”), and it does not include the pre-commitment early works capital costs, which are costs NexGen intends, in part or entirely, on expending prior to the FID. The pre-commitment early works scope includes preparing the site, completing initial freeze hole drilling, and building the supporting infrastructure (i.e., concrete batch plant, Phase I camp accommodations, and bulk fuel storage) required for the Rook I Project. Costs for the pre-commitment early works will total an estimated $158 million.

The Rook I FS Technical Report returned an after-tax NPV@8% of $3.47 billion and an IRR of 52.4% for the Base Case. The economic model was subjected to a sensitivity analysis to determine the effects of changing metals prices, grade, metal recovery, exchange rate, OPEX, CAPEX, labour and reagent costs. The NPV is most sensitive to metals prices, grade, metal recovery, and exchange rate. The sensitivity of the after-tax NPV and IRR are summarized in the following table using the price of uranium as the dependent variable.

NPV and IRR Sensitivity to Uranium Price

Uranium Price (US$/lb U3O8)	After-Tax NPV	After-Tax IRR
$100/lb U3O8	$8.13 Billion	81.6%
$90/lb U3O8	$7.20 Billion	76.8%
$80/lb U3O8	$6.27 Billion	71.5%
$70/lb U3O8	$5.33 Billion	65.8%
$60/lb U3O8	$4.40 Billion	59.5%
$50/lb U3O8 (Base Case)	$3.47 Billion	52.4%
$40/lb U3O8	$2.53 Billion	44.0%

Permitting, Regulatory, and Engagement

During the quarter, work advanced on the EA for the Project, with continued technical, modelling and assessment work conducted in support of the development of the draft EIS, and submission of the EIS was completed on June 21, 2022. On July 12, 2022, the CNSC announced their acceptance of the EIS which followed a 30-day period during which the CNSC conducted a conformance review of the EIS submission and confirmed no comments or conditions. Further, the acceptance marks the formal commencement of the 90-day period during which the CNSC will coordinate both the Federal technical and public review of the EIS.

Similarly, work advanced on the Licence Application in order to obtain a Uranium Mine and Mill Licence from the CNSC for the Project.

The Company is continuing its longstanding engagement with the communities within the proximity to the Rook I Project, as per the Study Agreements entered into with four Indigenous groups in Q4 2019 (the “Study Agreements”). The Study Agreements provide the following:

● a framework for working collaboratively to advance the EA and exchange information that will be used to inform the Crown as it undertakes its duty to consult.

● funding to each Indigenous group and outline a collaborative process for formal engagement to support the inclusion of Indigenous knowledge in the EA.

● outline processes for identifying potential effects to Indigenous rights, treaty rights, and socio-economic interests, and determining avoidance and accommodation measures in relation to the Rook I Project.

The Company and the Indigenous communities have committed to engagement through Joint Working Groups (“JWGs”) to support the inclusion of each community’s traditional knowledge throughout the EA process, including incorporating traditional land use and dietary studies undertaken by each of the respective communities. The Company has and will continue to provide funding for all aspects of the above, including the JWGs, and to lead, review and independently confirm the Traditional Land Use studies for inclusion into the EA. Further, the Study Agreements confirm that the parties will negotiate benefit agreements in good faith.

In Q2 2022, the Company signed an IBA with the CRDN. During 2021, the Company signed an IBA with the BRDN and a Mutual Benefit Agreement (“MBA”) with the BNDN covering all phases of the Rook I Project.

OPERATIONS OUTLOOK

The Company intends to advance the development of the Rook I Project as outlined in the Rook I FS Technical Report. The work will include:

● completing FEED with Hatch Ltd. by advancing overall engineering to a 40-45% level of completion, that will form the control budget, and define a project execution schedule (Level 3 Schedule); and

● conducting site confirmation and process plant optimization studies to support FEED.

Through 2022, the Company will continue to advance the EA and licensing activities towards the submission of the Final EIS and Licensing application in order to obtain a Uranium Mine and Mill License from the CNSC, and continue engagement with regulators and communities.

Three months ended June 30, 2022 versus three months ended June 30, 2021

During the three months ended June 30, 2022 (the “Current Quarter”), NexGen recorded net income of $17.6 million or $0.03 basic earnings per share attributable to NexGen shareholders compared to the three months ended June 30, 2021 (the “Comparative Quarter”) with a net loss of $19.8 million or $0.04 basic loss per share attributable to NexGen shareholders, representing an improvement of $37.4 million quarter over quarter. The improved result was primarily due to the following:

● Salaries, benefits, and directors’ fees of $1.9 million in the Current Quarter remained consistent with the Comparative Quarter.

● Office, administrative, and travel costs increased by $0.9 million in the Current Quarter compared to the Comparative Quarter. The increase is primarily related to additional travel (in line with Covid-19 guidelines), implementation of a new enterprise resource planning system, and costs related to IsoEnergy expanding its executive team.

● Professional fees and insurance increased by $0.9 million from $0.5 million in the Comparative Quarter to $1.4 million in the Current Quarter primarily due to increased insurance costs, additional recruiting costs for new staff to support the Rook I Project, the timing of filing fee payments, and increased corporate development costs in IsoEnergy.

NexGen Energy Ltd.

Management’s Discussion and Analysis for the three and six months ended June 30, 2022

(expressed in thousands of Canadian dollars, except as noted)

● Share based compensation decreased by $5.1 million from $11.4 million during the Comparative Quarter to $6.3 million in the Current Quarter. The decrease is primarily due to the grant of stock options in the Comparative Quarter compared to no stock option granted in the Current Quarter. The remaining share based compensation relates to the amortization of the Black Scholes grant values of previous grants.

● The Company recognized a mark-to-market gain on the Convertible Debentures (as defined in the “Outstanding Convertible Debentures” section below) of $28.5 million during the Current Quarter compared to a mark-to-market loss of $5.9 million during the Comparative Quarter. Mark-to-market gains and losses result from the fair value re-measurement of the Convertible Debentures at each reporting date, with any changes in the fair value being recognized in the net income (loss) and comprehensive income (loss) for the period. The mark-to-market gain for the Current Quarter is mainly due to a decrease in the Company and IsoEnergy’s share price during the Current Quarter.

● Deferred income tax expense decreased by $0.8 million from a $0.5 million expense in the Comparative Quarter to a $0.3 million recovery in the Current Quarter. The difference is mainly due to the recognition of a deferred tax expense in the Comparative Quarter from the gain on sale of assets in IsoEnergy compared to none in the Current Quarter.

Six months ended June 30, 2022 versus six months ended June 30, 2021

During the six months ended June 30, 2022 (the “Current Period”), NexGen recorded a net loss of $12.8 million or $0.03 basic loss per share attributable to NexGen shareholders compared to the six months ended June 30, 2021 (the “Comparative Period”) with a net loss of $87.9 million or $0.19 basic loss per share attributable to NexGen shareholders, representing a decrease in net loss of $75.1 million quarter over quarter. The decrease in net loss was primarily due to the following:

● Salaries, benefits, and directors’ fees decreased by $0.8 million from $4.5 million during the Comparative Period to $3.7 million for the Current Period. The Current Period included costs related to the increased workforce and the appointment of key personnel since the Comparative Period. The Comparative Period included the financial impact of the resignation of IsoEnergy’s former CEO.

● Office, administrative, and travel costs increased by $1.2 million in the Current Period compared to the Comparative Period. The increase is primarily related to additional travel (in line with Covid-19 guidelines), implementation of a new enterprise resource planning system, and costs related to IsoEnergy expanding its executive team.

● Professional fees and insurance increased by $0.7 million from $1.3 million in the Comparative Period to $2.0 million in the Current Period due to increased insurance costs, additional recruiting costs for new staff to support the Rook I Project and increased corporate development and legal fees in IsoEnergy.

● Share based compensation in the Current Period was $13.7 million compared to $13.6 million in the Comparative Period. The Current Period share based compensation primarily related to the amortization of Black Scholes grant values for the stock options granted in 2021. The Comparative Period share based compensation related primarily to the Black Scholes grant values of the stock options granted during the Comparative Period.

● The Company recognized a mark-to-market gain on the Convertible Debentures (as defined in the “Outstanding Convertible Debentures” section below) of $10.1 million during the Current Period compared to a mark-to-market loss of $64.9 million during the Comparative Period.

NexGen Energy Ltd.

Management’s Discussion and Analysis for the three and six months ended June 30, 2022

(expressed in thousands of Canadian dollars, except as noted)

Mark-to-market gains and losses result from the fair value re-measurement of the Convertible Debentures at each reporting date, with any changes in the fair value being recognized in net income (loss) and comprehensive income (loss) for the period. The mark-to-market gain for the Current Period is mainly due to a decrease in the Company and IsoEnergy’s share price during the Current Period.

● The interest expense on the Convertible Debentures decreased by $1.7 million from $2.7 million in the Comparative Period to $1.0 million in the Current Period. The decrease is due to the conversion of the 2016 and 2017 Debentures into common shares of the Company in the first quarter of 2021.

● Deferred income tax expense decreased by $0.8 million from a $0.3 million expense in the Comparative Period to a $0.5 million recovery in the Current Period. The difference is mainly due to the recognition of a deferred tax expense in the Comparative Period from the gain on sale of assets in IsoEnergy compared to none in the Current Period.

NexGen Energy Ltd.

Management’s Discussion and Analysis for the three and six months ended June 30, 2022

(expressed in thousands of Canadian dollars, except as noted)

Liquidity and Capital Resources

On March 11, 2021 and March 16, 2021, NexGen closed a bought deal equity offering (“the Offering”) for aggregate gross proceeds of approximately $150.3 million and the associated over-allotment option (the “Over-Allotment Option”) for aggregate gross proceeds of approximately $22.5 million, respectively, for total gross proceeds of approximately $172.8 million. The Company intends to apply the net proceeds of the Offering and Over-Allotment Option towards the development of the Rook I Project, including site investigations, process plant optimizations and engineering, pre-commitment early works, and for general working capital. The following table sets forth a comparison of the disclosure regarding NexGen’s estimated use of proceeds in its final short form prospectus dated March 8, 2021, which is available on SEDAR at www.sedar.com, and its actual use of such funds as at June 30, 2022:

$000s	Estimated Use of Net Proceeds		Actual Use of Net Proceeds
Development of Rook I Project
Site Investigation		$        9,000		$    8,267
Process Plant Optimizations		1,500		697
Engineering		35,000		24,426
Pre-Commitment Early Works		94,500		-
General working capital		23,290		-
Total1		$    163,290		$    33,390

¹ The net proceeds of the Offering and the Over-Allotment Option reflect the aggregate gross proceeds of $172.8 million after deducting underwriters’ fees and transaction expenses of $9.5 million.

The Company’s actual use of net proceeds from the Offering remains on schedule and as planned.

NexGen had a working capital surplus of $157.4 million as at June 30, 2022 (December 31, 2021 – $205.1 million). The Company currently has sufficient cash to fund its current operating and administration costs.

The decrease in working capital of $47.7 million from December 31, 2021 to June 30, 2022 was primarily attributable to expenditure to advance the Rook I Project.

The net change in cash position at June 30, 2022 compared to March 31, 2022 was a decrease of $26.3 million, attributable to the following components of the statement of cash flows:

● NexGen’s operating outflow before working capital adjustments was $4.3 million during the Current Quarter (Comparative Quarter – outflow of $2.9 million) due to the non-recurring nature of the resignation of IsoEnergy’s former CEO in the Comparative Quarter, offset by increased operational costs in the Current Quarter.

● Investing activities used $20.2 million in the Current Quarter, associated primarily with the development of the Rook I Project (Comparative Quarter – outflow of $5.1 million).

● Financing activities used $0.7 million in the Current Quarter (Comparative Quarter – inflow of $17.0 million) primarily due to the payment of interest. The Comparative Quarter inflow was due to stock option exercises resulting in $16.9 million of cash inflows compared to $0.2 million in the Current Quarter.

Management’s Discussion and Analysis for the three and six months ended June 30, 2022

(expressed in thousands of Canadian dollars, except as noted)

The net change in cash position at June 30, 2022 compared to December 31, 2021 was a decrease of $40.6 million, attributable to the following components of the statement of cash flows:

● NexGen’s operating outflow before working capital adjustments was $7.9 million during the Current Period (Comparative Period – outflow of $7.0 million) due to increased operational costs in the Current Period.

● Investing activities used $31.1 million in the Current Period, associated primarily with the development of the Rook I Project (Comparative Period – outflow of $13.4 million).

● Financing activities generated $0.1 million in the Current Period (Comparative Period – inflow of $181.4 million), primarily related to the proceeds from the exercise of stock options. The Comparative Period included the Offering and Over-Allotment Option for net proceeds of $163.5 million that did not occur in the Current Period.

Capital Management

The Company manages its capital structure, and adjusts it, based on the funds available to the Company, to support the acquisition, exploration and evaluation of assets. To effectively manage the entity’s capital requirements, the Company has in place a planning, budgeting and forecasting process to help determine the funds required to ensure the Company has the appropriate liquidity to meet its operating and growth objectives.

In the management of capital, the Company considers all components of equity and debt, net of cash, and is dependent on third-party financing, whether through debt, equity, or other means. Although the Company has been successful in raising funds to date, there is no assurance that the Company will be successful in obtaining the required financing in the future or that such financing will be available on terms acceptable to the Company.

The properties in which the Company currently has an interest are in the exploration and development stage. As such, the Company has historically relied on the equity markets to fund its activities. The Company will continue to assess new properties and seek to acquire an interest in additional properties if it determines that there is sufficient geologic or economic potential and if it has adequate financial resources to do so.

As discussed in the section above entitled “Liquidity and Capital Resources”, the Company completed the Offering and Over-Allotment Option, raising gross proceeds of approximately $172.8 million in the period ended March 31, 2021. The Company holds sufficient US dollars to make all interest payments due under the Convertible Debentures until maturity.

The Company is not subject to externally imposed capital requirements. There were no changes in the Company’s approach to capital management during the period ended June 30, 2022.

NexGen does not derive any revenue from its operations except for interest income from its cash. Its primary focus is the acquisition, exploration, evaluation and development of resource properties in addition to the development of the Rook I Project.

The significant fluctuations in income(loss) are mainly the result of mark-to-market gains or losses recognized on the fair value re-valuation of the Convertible Debentures at each quarter driven primarily by the change in share price of the Company and IsoEnergy, with any changes in the fair value being recognized in the income(loss) for the quarter.

Interest income recorded as finance income has fluctuated depending on cash balances available to generate interest and the earned rate of interest.

The income(loss) per period has also fluctuated depending on the Company’s activity level and periodic variances in certain items. Quarterly periods are therefore not comparable due to the nature and timing of exploration and development activities.

ACCOUNTING POLICY OVERVIEW

Critical Accounting Policies and Judgements

The critical judgements that the Company’s management has made in the process of applying the Company’s accounting policies, apart from those involving estimations, that have the most significant effect on the amounts recognized in the Company’s consolidated financial statements include impairment of exploration and evaluation assets, deferred income taxes, convertible debentures, and share-based payments. Refer to the Annual Financial Statements for further detail of the Company’s Critical Accounting Estimates.

Key Sources of Estimation Uncertainty

The preparation of consolidated financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and related notes to the consolidated financial statements. Estimates and assumptions are continuously evaluated and are based on management’s experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

The significant assumptions about the future and other major sources of estimation uncertainty as at the end of the reporting period that have a significant risk of resulting in a material adjustment to the carrying amounts of the Company’s assets and liabilities include impairment of exploration and evaluation assets, deferred income taxes, convertible debentures, and share-based payments. Refer to the Annual Financial Statements for further detail of the Company’s Critical Accounting Estimates.

Changes in Accounting Policies including Initial Adoption

The Company has had no significant changes in accounting policies. Refer to the Annual Financial Statements for further details of the Company’s changes in accounting policies.

FINANCIAL INSTRUMENTSAND RISK MANAGEMENT

The Company’s financial instruments consist of cash, amounts receivables, accounts payable and accrued liabilities and convertible debentures.

Financial instruments measured at fair value are classified into one of three levels in the fair value hierarchy according to the relative reliability of the inputs used to estimate the fair values.

The three levels of the fair value hierarchy are:

● Level 1 – unadjusted quoted prices in active markets for identical assets or liabilities

● Level 2 – inputs other than quoted prices that are observable for the asset or liability either directly or indirectly; and

● Level 3 – inputs that are not based on observable market data.

The fair values of the Company’s cash, amounts receivables, and accounts payable and accrued liabilities approximate their carrying values due to their short-term nature.

The marketable securities are re-measured at fair value at each reporting date with any change in fair value recognized other comprehensive income (loss). The marketable securities are classified as Level 1.

The Convertible Debentures are re-measured at fair value at each reporting date with any change in fair value recognized in profit or loss with the exception that under IFRS 9, the change in fair value that is attributable to change in credit risk is presented in other comprehensive income (loss). The Convertible Debentures are classified as Level 2.

Risk Factors

Readers of this Management’s Discussion and Analysis should give careful consideration to the information included or incorporated by reference in this document and the Company’s condensed interim consolidated financial statements and related notes for the three and six months ended June 30, 2022. For further details of risk factors, please refer to the most recent Annual Information Form dated February 25, 2022 filed on SEDAR at http://www.sedar.com, the Annual Financial Statements, and the below discussions.

Financial Risks

The Company is exposed to varying degrees of a variety of financial instrument related risks. The Board approves and monitors the risk management processes, inclusive of counterparty limits, controlling and reporting structures. The type of risk exposure and the way in which such exposure is managed is provided as follows:

Credit Risk

Credit risk is the risk that one party to a financial instrument will fail to discharge an obligation and cause the other party to incur a financial loss. Financial instruments potentially subject to credit risk are cash and amounts receivable. The Company holds cash with large Canadian banks. The Company’s amounts receivable consists of input tax credits receivable from the Government of Canada and interest accrued on cash. Accordingly, the Company does not believe it is subject to significant credit risk.

20

NexGen Energy Ltd.

Management’s Discussion and Analysis for the three and six months ended June 30, 2022

(expressed in thousands of Canadian dollars, except as noted)

The Company’s maximum exposure to credit risk is as follows:

	June 30, 2022		December 31, 2021
Cash	$	161,237	$	201,804
Amounts receivable		862		1,178
	$	162,099	$	202,982

Liquidity Risk

Liquidity risk is the risk that an entity will encounter difficulty in raising funds to meet commitments associated with financial instruments. Liquidity requirements are managed based on expected cash flows to ensure that there is sufficient capital to meet short-term obligations. The Company’s approach to managing liquidity risk is to ensure that it will have sufficient liquidity to meet liabilities when due. As at June 30, 2022, NexGen had cash of $161,237 to settle current liabilities of $13,475.

Foreign Currency Risk

The functional currency of the Company and its subsidiaries is the Canadian dollar. The Company is affected by currency transaction risk and currency translation risk. Consequently, fluctuations of the Canadian dollar in relation to other currencies impact the fair value of financial assets, liabilities and operating results. Financial assets and liabilities subject to currency translation risk primarily includes US dollar denominated cash, US dollar accounts payable, and the Convertible Debentures. The Company maintains Canadian and US dollar bank accounts in Canada.

The Company is exposed to foreign exchange risk on its US dollar denominated Convertible Debentures. At maturity the US$21 million principal amount of the Convertible Debentures is due in full, and prior to maturity, at a premium upon the occurrence of certain events. The Company holds sufficient US dollars to make all cash interest payments due under the Convertible Debentures until maturity but not to pay the principal amount. Accordingly, the Company is subject to risks associated with fluctuations in the Canadian/US dollar exchange rate that may make the Convertible Debentures more costly to repay.

As at June 30, 2022, the Company’s US dollar net financial liabilities were US$35,959. Thus a 10% change in the Canadian dollar versus the US dollar exchange rates would give rise to a $4,630 change in net income (loss) and comprehensive income (loss).

The Company has not entered into any agreements or purchased any instruments to hedge possible currency risks at this time.

Equity and Commodity Price Risk

The Company is exposed to price risk with respect to commodity and equity prices. Equity price risk is defined as the potential adverse impact on the Company’s earnings due to movements in individual equity prices or general movements in the level of the stock market. Accordingly, significant movements in share price may affect the valuation of the marketable securities and Convertible Debentures which may adversely impact its earnings.

Commodity price risk is defined as the potential adverse impact on earnings and economic value due to commodity price movements and volatility. Future declines in commodity prices may impact the valuation of long-lived assets. The Company closely monitors commodity prices of uranium, individual equity movements, and the stock market to determine the appropriate course of action, if any, to be taken by the Company.

Management’s Discussion and Analysis for the three and six months ended June 30, 2022

(expressed in thousands of Canadian dollars, except as noted)

Interest Rate Risk

Interest rate risk is the risk that the future cash flows of a financial instrument will fluctuate due to changes in market interest rates. The Company holds its cash in bank accounts that earn variable interest rates. Due to the short-term nature of these financial instruments, fluctuations in market rates do not have a significant impact on the estimated fair value of the Company’s cash balances as of June 30, 2022. The Company manages interest rate risk by maintaining an investment policy for short-term investments. This policy focuses primarily on preservation of capital and liquidity. The Company monitors the investments it makes and is satisfied with the credit rating of its banks. The 2020 Debentures and IsoEnergy Debentures, in an aggregate principal amount of US$21 million, carry fixed interest rates of 7.5% and 8.5% respectively and are not subject to interest rate fluctuations.

Other Risk Factors

The operations of the Company are speculative due to the high-risk nature of its business which is the exploration of mining properties. For a comprehensive list of the risks and uncertainties facing the Company, please see “Risk Factors” in the Company’s most recent annual information form and below under “Industry and Economic Factors that May Affect the Business”. These are not the only risks and uncertainties that NexGen faces. Additional risks and uncertainties not presently known to the Company or that the Company currently considers immaterial may also impair its business operations. These risk factors could materially affect the Company’s future operating results and could cause actual events to differ materially from those described in forward-looking statements relating to the Company.

During 2020, the World Health Organization declared a global pandemic known as COVID-19 and governments around the world enacted measures to combat the spread of the virus. The duration and impact of the COVID-19 outbreak is not known at this time, but the risks to the Company may include, but are not limited to, delays in the previously disclosed timelines and activity levels associated with the Company’s baseline engineering, environmental assessment and the ability to raise funds through debt and equity markets. To date, the Company’s operations and ability to raise funds have not been significantly impacted. The Company has implemented proper COVID-19 protocols at each of its locations that are in line with the respective regional health authorities COVID-19 guidelines.

Negative Impacts by an Outbreak of Infectious Disease or Pandemic

An outbreak of infectious disease, pandemic or a similar public health threat, such as the COVID-19 pandemic, and the response thereto, could adversely impact the Company, both operationally and financially. The global response to the COVID-19 pandemic has resulted in, among other things, border closures, severe travel restrictions and extreme fluctuations in financial and commodity markets. Additional measures may be implemented by one or more governments around the world in jurisdictions where the Company operates. Labour shortages due to illness, Company or government-imposed isolation programs, or restrictions on the movement of personnel or possible supply chain disruptions could result in a reduction or interruption of the Company’s operations, including operational shutdowns or suspensions. The inability to continue ongoing exploration and development work could have a material adverse effect on the Company’s future cash flows, earnings, results of operations and financial condition. The extent to which COVID-19 and any other pandemic or public health crisis impacts the Company’s business, affairs, operations, financial condition, liquidity, availability of credit and results of operations will depend on future developments that are highly uncertain and cannot be accurately predicted, including new information which may emerge concerning the severity of and the actions required to contain the COVID-19 pandemic or remedy its impact, among others.

Management’s Discussion and Analysis for the three and six months ended June 30, 2022

(expressed in thousands of Canadian dollars, except as noted)

Negative Operating Cash Flow and Dependence on Third Party Financing

The Company has no source of operating cash flow and there can be no assurance that the Company will ever achieve profitability. Accordingly, the Company is dependent on third-party financing to continue exploration activities on the Company’s properties, maintain capacity and satisfy contractual obligations. Accordingly, the amount and timing of expenditures depends on the Company’s cash reserves and access to third-party financing. Failure to obtain such additional financing could result in delay or indefinite postponement of further exploration and development of the Company’s properties, including the Rook I Project, or require the Company to sell one or more of its properties (or an interest therein). In particular, there can be no assurance that the Company will have achieved profitability prior to the maturity date and may be required to finance the repayment of all or a part of the principal amount of the Convertible Debentures. Failure to repay the Convertible Debentures in accordance with the terms thereof would have a material adverse effect on the Company’s financial position.

Uncertainty of Additional Financing

As stated above, the Company is dependent on third-party financing, whether through debt, equity, or other means. Although the Company has been successful in raising funds to date, there is no assurance that the Company will be successful in obtaining required financing in the future or that such financing will be available on terms acceptable to the Company. The Company’s access to third-party financing depends on several factors including the price of uranium, the results of ongoing exploration, the Company’s obligations under the Convertible Debentures, a claim against the Company, a significant event disrupting the Company’s business or uranium industry generally, or other factors may make it difficult or impossible to obtain financing through debt, equity, or other means on favourable terms, or at all. As previously stated, failure to obtain such additional financing could result in delay or indefinite postponement of further exploration and development of the Company’s properties, including the Rook I Project, or require the Company to sell one or more of its properties (or an interest therein).

The Price of Uranium Price and Alternate Sources of Energy

The price of the Company’s securities is highly sensitive to fluctuations in the price of uranium. Historically, the fluctuations in these prices have been, and are expected to continue to be, affected by numerous factors beyond the Company’s control. Such factors include, among others: demand for nuclear power; political and economic conditions, including the outbreak of war or levying of sanctions, in or by uranium producing and consuming countries; public and political response to a nuclear accident; improvements in nuclear reactor efficiencies; reprocessing of used reactor fuel and the re-enrichment of depleted uranium tails; sales of excess inventories by governments and industry participants; and production levels and production costs in key uranium producing countries.

In addition, nuclear energy competes with other sources of energy like oil, natural gas, coal and hydroelectricity. These sources are somewhat interchangeable with nuclear energy, particularly over the longer term. If lower prices of oil, natural gas, coal and hydroelectricity are sustained over time, it may result in lower demand for uranium concentrates and uranium conversion services, which, among other things, could lead to lower uranium prices. Growth of the uranium and nuclear power industry will also depend on continuing and growing public support for nuclear technology to generate electricity. Unique political, technological and environmental factors affect the nuclear industry, exposing it to the risk of public opinion, which could have a negative effect on the demand for nuclear power and increase the regulation of the nuclear power industry. An accident at a nuclear reactor anywhere in the world could affect acceptance of nuclear energy and the future prospects for nuclear generation.

All of the above factors could have a material and adverse effect on the Company’s ability to obtain the required financing in the future or to obtain such financing on terms acceptable to the Company, resulting in material and adverse effects on its exploration and development programs, cash flow and financial condition.

Exploration Risks

Exploration for mineral resources involves a high degree of risk and few properties that are explored are ultimately developed into producing mines. The risks and uncertainties inherent in exploration activities include but are not limited to: general economic, market and business conditions, the regulatory process and actions, failure to obtain necessary permits and approvals, technical issues, new legislation, competitive and general economic factors and conditions, the uncertainties resulting from potential delays or changes in plans, the occurrence of unexpected events and management’s capacity to execute and implement its future plans. There is also no assurance that even if commercial quantities of ore are discovered that it will be developed and brought into commercial production. The commercial viability of a mineral deposit once discovered is also dependent upon a number of factors, most of which factors are beyond the control of the Company and may result in the Company not receiving adequate return on investment capital.

Uninsurable Risks

Mining operations generally involve a high degree of risk. Exploration, development and production operations on mineral properties involve numerous risks, including but not limited to unexpected or unusual geological operating conditions, seismic activity, rock bursts, cave-ins, fires, floods, landslides, earthquakes and other environmental occurrences, and political and social instability, any of which could result in damage to, or destruction of life or property, environmental damage and possible legal liability. Although the Company believes that appropriate precautions to mitigate these risks are being taken, operations are subject to hazards such as equipment failure or failure of structures, which may result in environmental pollution and consequent liability. It is not always possible to obtain insurance against all such risks and the Company may decide not to insure against certain risks because of high premiums or other reasons. Should such liabilities arise, they could reduce or eliminate the Company’s future profitability and result in increasing costs and a decline in the value of the common shares. While the Company may obtain insurance against certain risks in such amounts as it considers adequate, the nature of these risks is such that liabilities could exceed policy limits or be excluded from coverage. The potential costs that could be associated with any liabilities not covered by insurance or in excess of insurance coverage may cause substantial delays and require significant capital outlays, thereby adversely affecting the Company’s business and financial condition.

Reliance upon Key Management and Other Personnel

The Company relies on the specialized skills of management in the areas of mineral exploration, geology and business negotiations and management. The loss of any of these individuals could have an adverse effect on the Company. The Company does not currently maintain key-man life insurance on any of its key employees. In addition, as the Company’s business activity continues to grow, it will require additional key financial, administrative and qualified technical personnel. Although the Company believes that it will be successful in attracting, retaining and training qualified personnel, there can be no assurance of such success. If it is not successful in attracting, retaining and training qualified personnel, the efficiency of the Company’s business could be affected, which could have an adverse impact on its future cash flows, earnings, results of operation and financial condition.

Imprecision of Mineral Resource Estimates

Mineral Resource figures are estimates, and no assurances can be given that the estimated levels of uranium will be produced. Such estimates are expressions of judgment based on knowledge, mining experience, analysis of drilling results and industry practices. Valid estimates made at a given time may significantly change when new information becomes available. While the Company believes that its Mineral Resource estimate is well established and reflects management’s best estimates, by their nature, Mineral Resource estimates are imprecise and depend, to a certain extent, upon statistical inferences which may ultimately prove unreliable. Should the Company encounter mineralization or formations different from those predicted by past sampling and drilling, resource estimates may have to be adjusted.

These are not the only risks and uncertainties that NexGen faces. Additional risks and uncertainties not presently known to the Company or that the Company currently considers immaterial may also impair its business operations. These risk factors could materially affect the Company’s future operating results and could cause actual events to differ materially from those described in forward-looking statements relating to the Company.

Industry and Economic Factors that May Affect the Business

The business of mining for minerals involves a high degree of risk. NexGen is an exploration and development company and is subject to risks and challenges similar to companies in a comparable stage and industry. These risks include, but are not limited to, the challenges of securing adequate capital, exploration, development and operational risks inherent in the mining industry; changes in government policies and regulations; the ability to obtain the necessary permitting; as well as global economic and uranium price volatility; all of which are uncertain.

The underlying value of the Company’s exploration and evaluation assets is dependent upon the existence and economic recovery of mineral reserves and is subject to, but not limited to, the risks and challenges identified above. Changes in future conditions could require material write-downs of the carrying value of the Company’s exploration and evaluation assets.

In particular, the Company does not generate revenue. As a result, the Company continues to be dependent on third-party financing to continue exploration and development activities on the Company’s properties, maintain capacity and satisfy contractual obligations including servicing the interest payments due on the Convertible Debentures and repaying the principal amount thereof at maturity (or sooner in the event of redemption in accordance with the terms of the Convertible Debentures). Accordingly, the Company’s future performance will be most affected by its access to financing, whether debt, equity or other means.

Access to such financing, in turn, is affected by general economic conditions, the price of uranium, exploration risks and the other factors described in the section entitled “Risk Factors” in the Company’s most recent annual information form.

For further information on Risk Factors, refer to those set forth in the Company’s Annual Information Form dated February 25, 2022, filed under the Company’s profile on SEDAR at www.sedar.com on EDGAR at www.sec.gov.

DISCLOSURE CONTROLS, PROCEDURES,AND INTERNAL CONTROLS OVER FINANCIAL REPORTING

Management maintains appropriate information systems, procedures and controls to provide reasonable assurance that information that is publicly disclosed is complete, reliable and timely. The Chief Executive Officer (the “CEO”) and Chief Financial Officer (the “CFO”) of the Company, along with the assistance of management under their supervision, have designed disclosure controls and procedures to provide reasonable assurance that material information relating to the Company is made known to the CEO and CFO, and have designed internal controls over financial reporting to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS.

Changes in Internal Controls

During the six months ended June 30, 2022, there were no changes in the Company’s internal control over financial reporting that materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

Limitations of Controls and Procedures

The Company’s management, including the Chief Executive Officer and Chief Financial Officer, believe that any disclosure controls and procedures or internal controls over financial reporting, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, they cannot provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been prevented or detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by unauthorized override of the control. The design of any systems of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Accordingly, because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.
