Notes to the Condensed Interim Consolidated Financial Statements
For the three and six months ended June 30, 2023 and 2022
(expressed in thousands of Canadian dollars, except as otherwise stated) - Unaudited

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, 2023, NexGen owns 49.7% of IsoEnergy’s outstanding common shares (December 31, 2022 - 50.1%).

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, 2023, the Company had an accumulated deficit of $415,546 and working capital of $102,397. Although the Company will be required to obtain additional funding in order to continue with the exploration and development of its mineral properties, the Company has sufficient working capital to meet its current obligations for the next twelve months.

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.

BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES

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, 2022 and 2021 (“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 8, 2023, the Audit Committee of the Board of Directors authorized these financial statements for issuance.

NexGen Energy Ltd.

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, 2023 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	49.7%

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

CRITICAL ACCOUNTING JUDGMENTS, ESTIMATES AND ASSUMPTIONS IN ACCOUNTING POLICIES

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.

MARKETABLE SECURITIES

Marketable securities consist of 10,755,000 common shares of 92 Energy Pty Ltd (“92 Energy”), 900,000 common shares of Consolidated Uranium Inc. (“CUR”), 5,907,600 common shares of Latitude Uranium Inc. (previously Labrador Uranium Inc.) (“Latitude Uranium”) and 2,857,150 warrants of Latitude Uranium exercisable at a price of $0.50 any time on or before April 5, 2026. As at June 30, 2023 IsoEnergy’s shareholding in 92 Energy represents 11.6% of the outstanding capital of 92 Energy.

On February 22, 2022, CUR completed its spin-out of Latitude Uranium through a plan of arrangement (the “Arrangement”). Pursuant to the Arrangement, CUR distributed, on a pro-rata basis, 0.214778 of Latitude Uranium shares for each CUR share held by CUR shareholders on February 22, 2022. Accordingly, IsoEnergy received 193,300 Latitude Uranium shares. On April 5, 2023, IsoEnergy subscribed to 5,714,300 subscription receipts of Latitude Uranium (“Subscription Receipts”) at a price of $0.35 per Subscription Receipt for total consideration of $2,000. On June 19, 2023, after completion of Latitude Uranium’s acquisition of a 100% interest in the Angilak Uranium Project in Nunavut Territory from ValOre Metals Corp., the Subscription Receipts were exercised into one unit of Latitude Uranium, consisting of one common share of Latitude Uranium and one-half of one common share purchase warrant, exercisable at a price of $0.50 at any time on or before April 5, 2026.

The carrying value of marketable securities is based on the estimated fair value of the common shares and warrants, respectively determined using published closing share prices and the Black-Scholes option pricing model.

During the three and six months ended June 30, 2023, the Company recognized a loss of $173 and $562, respectively, associated with the mark to market valuation of the 10,755,000 shares of 92 Energy, 900,000 shares of CUR, and 5,907,600 shares and 2,857,150 warrants of Latitude Uranium (three and six months ended June 30, 2022 - loss of $2,359 and $3,283, respectively) which is recorded in the consolidated statement of net income (loss) and comprehensive income (loss). The fair value at June 30, 2023 of the marketable securities held in 92 Energy shares was $3,697 (December 31, 2022 - $4,253), CUR shares was $1,283 (December 31, 2022 - $1,458), Latitude Uranium shares was $1,772 (December 31, 2022 - $64) and Latitude Uranium warrants was $460 (December 31, 2022 - $nil), for a total marketable securities value at June 30, 2023 of $7,212 (December 31, 2022 - $5,775).

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, 2023			December 31, 2022
Equity	$	481,887		$	455,417
Convertible debentures (Note 8)		78,986			80,021
		560,873			535,438
Less: Cash		(100,571	)		(134,447	)

FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

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

NexGen Energy Ltd.

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 and warrants 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 and the warrants as Level 2.

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, amounts receivable, and lease 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. The lease receivable is secured by the leased equipment. 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, 2023		December 31, 2022
Cash	$	100,571	$	134,447
Amounts receivable		1,119		1,801
Lease receivable		4,100		—
	$	105,790	$	136,248

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, 2023, NexGen had cash of $100,571 to settle current liabilities of $17,721.

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, 2020 IsoEnergy Debentures and 2022 IsoEnergy Debentures. At maturity, the US$25 million principal amount of the 2020 Debentures, 2020 IsoEnergy Debentures and 2022 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, 2020 IsoEnergy Debentures and 2022 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, 2020 IsoEnergy Debentures and 2022 IsoEnergy Debentures more costly to repay.

As at June 30, 2023, the Company’s US dollar net financial liabilities were US$47,394. Thus a 10% change in the Canadian dollar versus the US dollar exchange rates would give rise to a $6,276 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, 2023. 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, 2020 IsoEnergy Debentures and 2022 IsoEnergy Debentures, in an aggregate principal amount of US$25 million, carry fixed interest rates of 7.5%, 8.5% and 10.0% respectively and are not subject to interest rate fluctuations.
