NexGen Energy Ltd.

Notes to the Condensed Interim Consolidated Financial Statements

For the three and six months ended June 30, 2022 and 2021

(expressed in thousands of Canadian dollars, except as otherwise stated) - Unaudited

1. REPORTING ENTITY

NexGen Energy Ltd. (“NexGen” or the “Company”) is an exploration and development stage entity engaged in the acquisition, exploration and evaluation and development of uranium properties in Canada. The Company was incorporated pursuant to the provisions of the British Columbia Business Corporations Act on March 8, 2011. The Company’s registered records office is located on the 25th Floor, 700 West Georgia Street, Vancouver, B.C., V7Y 1B3.

The Company is listed on the Toronto Stock Exchange (the “TSX”) under the symbol “NXE”, and is a reporting issuer in each of the provinces of Canada other than Québec. On July 2, 2021, the Company commenced trading on the Australian Stock Exchange (the “ASX”) under the symbol “NXG”. On March 4, 2022 the Company up-listed from NYSE American exchange (the “NYSE American”) and began trading on the New York Stock Exchange (“NYSE”) under the symbol “NXE”.

In February 2016, the Company incorporated four wholly owned subsidiaries: NXE Energy Royalty Ltd., NXE Energy SW1 Ltd., NXE Energy SW3 Ltd., and IsoEnergy Ltd. (collectively, the “Subsidiaries”). The Subsidiaries were incorporated to hold certain exploration assets of the Company. In 2016, certain exploration and evaluation assets were transferred to each of IsoEnergy Ltd. (“IsoEnergy”), NXE Energy SW1 Ltd. and NXE Energy SW3 Ltd. Subsequent to the transfer, IsoEnergy shares were listed on the TSX-V. As of June 30, 2022, NexGen owns 50.1% of IsoEnergy’s outstanding common shares (December 31, 2021 – 51%).

2. NATURE OF OPERATIONS

As an exploration and development stage company, the Company does not have revenues and historically has recurring operating losses. As at June 30, 2022, the Company had an accumulated deficit of $344,800 and working capital of $157,417. The Company will be required to obtain additional funding in order to continue with the exploration and development of its mineral properties.

The business of exploring for minerals and development of projects 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. These risks include, but are not limited to, the challenges of securing adequate capital; development and operational risks inherent in the mining industry; changes in government policies and regulations; the ability to obtain the necessary environmental permits or, alternatively NexGen’s ability to dispose of its exploration and evaluation assets on an advantageous basis; as well as global economic and uranium price volatility; all of which are uncertain.

The underlying value of the 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 exploration and evaluation assets.

3. BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES

a) Basis of Presentation

These condensed interim consolidated financial statements have been prepared in accordance with International Accounting Standard (“IAS”) 34, Interim Financial Reporting, using accounting policies consistent with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board. Certain disclosures required by IFRS have been condensed or omitted in the following note disclosures as they are disclosed or have been disclosed on an annual basis only. Accordingly, these condensed interim consolidated financial statements should be read in conjunction with the consolidated financial statements for the years ended December 31, 2021 and 2020 (“annual financial statements”), which have been prepared in accordance with IFRS. These condensed interim consolidated financial statements follow the same accounting policies and methods of application as the annual financial statements.

On August 4, 2022, the Audit Committee of the Board of Directors authorized these financial statements for issuance.

(expressed in thousands of Canadian dollars, except as otherwise stated) - Unaudited

b) Basis of Consolidation

The accounts of the subsidiaries controlled by the Company are included in the condensed interim consolidated financial statements from the date that control commenced until the date that control ceases. Control is achieved where the Company has the power to govern the financial and operating policies of an entity so as to obtain benefits from its activities. The subsidiaries of the Company and their geographic locations at June 30, 2022 are as follows:

Name of Subsidiary	Location	Percentage Ownership
NXE Energy Royalty Ltd.	Canada	100%
NXE Energy SW1 Ltd.	Canada	100%
NXE Energy SW3 Ltd.	Canada	100%
IsoEnergy Ltd.	Canada	50.1%

Intercompany balances, transactions, income and expenses arising from intercompany transactions are eliminated in full on consolidation.

4. CRITICAL ACCOUNTING JUDGMENTS, ESTIMATES AND ASSUMPTIONS IN ACCOUNTING POLICIES

Judgments, estimates and assumptions are continually 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 judgments, estimates and assumptions made by management in applying the Company’s accounting policies are consistent with those that applied to the annual financial statements and actual results may differ from these estimates.

5. MARKETABLE SECURITIES

a) Clover, Gemini, and Tower uranium properties sale

In April 2021, the Company’s subsidiary, IsoEnergy, sold its interest in the Clover, Gemini and Tower uranium properties (“Properties”). IsoEnergy received cash of AUD $200 ($192) and 10,755,000 common shares of 92 Energy Pty Ltd. (“92 Energy”) at a price of $0.20 Australian Dollars (“AUD”) for a total value of AUD $2,151 ($2,068). In addition, IsoEnergy will retain a 2% Net Smelter Return (“NSR”) on the Properties.

The Properties had a book value of $24, which resulted in a gain of $2,236 in 2021.

b) Mountain Lake Option Agreement

In August 2021, IsoEnergy completed an option agreement (the “Option Agreement”) with International Consolidated Uranium Inc. (which subsequently changed its name to Consolidated Uranium Inc. (“CUR”)) to grant CUR the option to acquire a 100% interest in IsoEnergy’s Mountain Lake uranium property in Nunavut, Canada (the “Option”).

Under the terms of the Option Agreement and as consideration, CUR issued 900,000 common shares of CUR at a price of $1.64 per share for a total value of $1,476, and paid cash of $20. The Option is exercisable, at CUR’s election, on or before the second anniversary of receipt of TSXV approval (August 3, 2023) for additional consideration of $1,000 payable in cash or CUR shares. If the Option is exercised, IsoEnergy will be entitled to receive the following contingent payments in cash or CUR shares:

● If the uranium spot price reaches US$50 per pound, IsoEnergy will receive an additional $410

● If the uranium spot price reaches US$75 per pound, IsoEnergy will receive an additional $615

● If the uranium spot price reaches US$100 per pound, IsoEnergy will receive an additional $820

The spot price contingent payments will expire 10 years following the date the Option is exercised.

The Mountain Lake property had a book value of $126, which resulted in a gain of $1,370 in 2021.

At the date of these financial statements the Option has not been exercised by Consolidated Uranium.

On February 22, 2022, CUR completed its spin-out of Labrador Uranium Inc. (“LUR”) though a plan of arrangement (the “Arrangement”). Pursuant to the Arrangement, CUR distributed, on a pro-rata basis, 0.214778 of LUR shares for each CUR share held by CUR shareholders on February 22, 2022. Accordingly, IsoEnergy received 193,300 LUR shares.

During the three and six months ended June 30, 2022, the Company recognized a loss of $2,359 and $3,283, respectively, associated with the mark to market valuation of the 10,775,000 shares of 92 Energy, 900,000 shares of CUR and 193,300 shares of LUR (three and six months ended June 30, 2021 - $933 gain) which is recorded in the consolidated statement of net income (loss) and comprehensive income (loss). The fair value at June 30, 2022 of the marketable securities held in 92 Energy shares was $4,304 (December 31, 2021 - $6,732), CUR shares was $1,611 (December 31, 2021 - $2,583) and LUR shares was $118 (December 31, 2021 - $nil), for a total marketable securities value at June 30, 2022 of $6,033 (December 31, 2021 - $9,315).

2016 and 2017 Convertible Debentures

On February 18, 2021 and February 23, 2021, the holders of the 2016 and 2017 Debentures elected to convert their respective US$60 million aggregate principal amount of 7.5% unsecured convertible debentures, both due to mature on July 22, 2022, into common shares of the Company. The Company issued 25,794,247 and 22,289,088 common shares relating to the conversion of the principal of the 2016 and 2017 Debentures, respectively, and 89,729 and 87,316 common shares at a value of $848 relating to the accrued and unpaid interest up to the date of conversion for the 2016 and 2017 Debentures, respectively. The amounts recorded in other comprehensive income (loss) as a result of changes in credit risks of the 2016 and 2017 Debentures from inception through to conversion totaling losses of $4,016 were reclassified to accumulated deficit.

The fair value of the 2016 and 2017 Debentures at conversion was based on the number of shares issued at the closing share price on the conversion date. The closing share price on February 18, 2021 was $4.69 and $4.88 on February 23, 2021 and the conversion price for the 2016 Debentures was US$2.33 and US$2.69 for the 2017 Debentures. The fair value of the shares issued for interest was based on the closing share price on the date of issuance and recorded as interest expense in the consolidated statement of net income (loss) and comprehensive income (loss).

2020 Convertible Debentures

On May 27, 2020, the Company issued US$15 million principal amount of unsecured convertible debentures (the “2020 Debentures”). The Company received proceeds of $20,889 (US$15 million) and a 3% establishment fee of $627 (US$450) was paid to the debenture holders through the issuance of 348,350 common shares and a consent fee of $355 was paid to the investors of the 2016 and 2017 Debentures in connection with the financing through the issuance of 180,270 common shares. The fair value of the 2020 Debentures on issuance date was determined to be $20,262 (US$14,550). The 2020 Debentures bear interest at a rate of 7.5% per annum, payable semi-annually in US dollars on June 10 and December 10 in each year. Two thirds of the interest (equal to 5% per annum) is payable in cash and one third of the interest (equal to 2.5% per annum) is payable, subject to any required regulatory approval, in common shares of the Company, using the volume-weighted average trading price (“VWAP”) of the common shares on the exchange or market that has the greatest trading volume in the Company’s common shares for the 20 consecutive trading days ending three trading days preceding the date on which such interest payment is due. The 2020 Debentures are convertible, from time to time, into common shares of the Company at the option of the debenture holders under certain conditions. During the period ended June 30, 2022, the Company issued 42,252 shares for a value of $251 and paid $474 (US$375) associated with the interest payment.

The 2020 Debentures were valued using a convertible bond pricing model based on a system of two coupled Black-Scholes equations where the debt and equity components are separately valued based on different default risks and assumptions. The inputs used in the pricing model as at June 30, 2022 and December 31, 2021 are as follows:

13. CAPITAL MANAGEMENT

The Company manages its capital structure and adjusts it, based on the funds available to the Company, to support the acquisition, exploration, development 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. The Board of Directors does not establish quantitative return on capital criteria for management, but rather relies on the expertise of the Company’s management to sustain the future development of the business.

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 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 and convertible debt 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.

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.

In the management of capital, the Company includes the components of equity, and convertible debentures, net of cash.

Capital, as defined above, is summarized in the following table:

	June 30, 2022		December 31, 2021

14. FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

The Company’s financial instruments consist of cash, marketable securities, amounts receivable, 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.

For the three and six months ended June 30, 2022 and 2021

(expressed in thousands of Canadian dollars, except as otherwise stated) - Unaudited

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 receivable, 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 in other comprehensive income (loss) (Note 5). 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 the consolidated statement of net income (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) (Note 8). The convertible debentures are classified as Level 2.

Financial Risk

The Company is exposed to varying degrees of a variety of financial instrument-related risks. The Board approves and monitors the risk management processes, 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.

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.

The Company’s significant undiscounted commitments at June 30, 2022 are as follows:

	Less than 1 year		1 to 3 years		4 to 5 years		Over 5 years		Total
Trade and other payables	$	12,738	$	-	$	-	$	-	$	12,738
Convertible debentures (Note 8)		-		61,716		-		-		61,716

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, 2020 Debentures and IsoEnergy 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 2020 Debentures and IsoEnergy Debentures. At maturity, the US$21 million principal amount of the 2020 Debentures and IsoEnergy 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 2020 Debentures and IsoEnergy 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 2020 Debentures and IsoEnergy 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.

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.

15. NON-CONTROLLING INTERESTS

As at June 30, 2022, NexGen held 100% ownership of the subsidiaries with the exception of IsoEnergy, where it retained 50.1% of IsoEnergy’s outstanding common shares (December 31, 2021 – 51%) (Note 3b).

For financial reporting purposes, the assets, liabilities, results of operations, and cash flows of the Company’s wholly owned subsidiaries and non-wholly owned subsidiary, IsoEnergy, are included in NexGen’s consolidated financial statements. Third party investors’ share of the net income (loss) of IsoEnergy is reflected in the net income (loss) and comprehensive income (loss) attributable to non-controlling interests in the consolidated statements of net income (loss) and comprehensive income (loss).

As at June 30, 2022, the non-controlling interests in IsoEnergy was $29,619 (December 31, 2021 - $27,740).
