Cautionary Note to U.S. Investors

This news release includes Mineral Reserves and Mineral Resources classification terms that comply with reporting standards in Canada and the Mineral Reserves and the Mineral Resources estimates are made in accordance with NI 43-101. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ from the requirements of the Securities and Exchange Commission ("SEC") set by the SEC's rules that are applicable to domestic United States reporting companies.  Consequently, Mineral Reserves and Mineral Resources information included in this news release is not comparable to similar information that would generally be disclosed by domestic U.S. reporting companies subject to the reporting and disclosure requirements of the SEC Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made public by companies that report in accordance with U.S. standards.

Forward-Looking Information

The information contained herein contains "forward-looking statements" within the meaning of applicable United States securities laws and regulations and "forward-looking information" within the meaning of applicable Canadian securities legislation. "Forward-looking information" includes, but is not limited to, statements with respect to mineral reserve and mineral resource estimates, the 2021 Arrow Deposit, Rook I Project and estimates of uranium production, grade and long-term average uranium prices, anticipated effects of completed drill results on the Rook I Project, planned work programs, completion of further site investigations and engineering work to support basic engineering of the project and expected outcomes. Generally, but not always, forward-looking information and statements can be identified by the use of words such as "plans", "expects", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", or "believes" or the negative connotation thereof or variations of such words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be achieved" or the negative connotation thereof. Statements relating to "mineral resources" are deemed to be forward-looking information, as they involve the implied assessment that, based on certain estimates and assumptions, the mineral resources described can be profitably produced in the future.

Forward-looking information and statements are based on the then current expectations, beliefs, assumptions, estimates and forecasts about NexGen's business and the industry and markets in which it operates. Forward-looking information and statements are made based upon numerous assumptions, including among others, that the mineral reserve and resources estimates and the key assumptions and parameters on which such estimates are based are as set out in this news release and the technical report for the property, the results of planned exploration activities are as anticipated, the price and market supply of uranium, the cost of planned exploration activities, that financing will be available if and when needed and on reasonable terms, that third party contractors, equipment, supplies and governmental and other approvals required to conduct NexGen's planned exploration activities will be available on reasonable terms and in a timely manner and that general business and economic conditions will not change in a materially adverse manner. Although the assumptions made by the Company in providing forward-looking information or making forward-looking statements are considered reasonable by management at the time, there can be no assurance that such assumptions will prove to be accurate in the future.

Forward-looking information and statements also involve known and unknown risks and uncertainties and other factors, which may cause actual results, performances and achievements of NexGen to differ materially from any projections of results, performances and achievements of NexGen expressed or implied by such forward-looking information or statements, including, among others, the existence of negative operating cash flow and dependence on third party financing, uncertainty of the availability of additional financing, the risk that pending assay results will not confirm previously announced preliminary results, conclusions of economic valuations, the risk that actual results of exploration activities will be different than anticipated, the cost of labour, equipment or materials will increase more than expected, that the future price of uranium will decline or otherwise not rise to an economic level, the appeal of alternate sources of energy to uranium-produced energy, that the Canadian dollar will strengthen against the U.S. dollar, that mineral resources and reserves are not as estimated, that actual costs or actual results of reclamation activities are greater than expected, that changes in project parameters and plans continue to be refined and may result in increased costs, of unexpected variations in mineral resources and reserves, grade or recovery rates or other risks generally associated with mining, unanticipated delays in obtaining governmental, regulatory or First Nations approvals, risks related to First Nations title and consultation, reliance upon key management and other personnel, deficiencies in the Company's title to its properties, uninsurable risks, failure to manage conflicts of interest, failure to obtain or maintain required permits and licences, risks related to changes in laws, regulations, policy and public perception, as well as those factors or other risks as more fully described in NexGen's Annual Information Form dated March 6, 2024 filed with the securities commissions of all of the provinces of Canada except Quebec and in NexGen's 40-F filed with the United States Securities and Exchange Commission, which are available on SEDAR+ at www.sedarplus.ca and Edgar at www.sec.gov .

Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in the forward-looking information or statements or implied by forward-looking information or statements, there may be other factors that cause results not to be as anticipated, estimated or intended. Readers are cautioned not to place undue reliance on forward-looking information or statements due to the inherent uncertainty thereof.

NexGen Energy Ltd. ("NexGen" or the "Company") (TSX: NXE) (NYSE: NXE) (ASX: NXG) is pleased to announce that it has entered into a binding term sheet with MMCap International Inc. SPC ("MMCap") for the purchase (the "Purchase") of 2,702,410 pounds natural uranium concentrate (" U 3 O 8 ") for an aggregate purchase price of US$250 million based on the five day average UxC spot price.

In satisfaction of the purchase price for the U ₃ O _8, the Company has agreed to issue US$250 million aggregate principal amount of unsecured convertible debentures (the "Debentures"). The Debentures will be convertible at the holder's option into approximately 23 million common shares of NexGen (the "Common Shares") equivalent to ~4.3% of the Company's issued and outstanding Common Shares.

Upon closing of the previously announced Australian Chess Depository Interest ("CDI") offering, as well as this transaction with MMCap, the Company will have ~C$600 million in cash and US$250 million worth of physical uranium on its balance sheet.

Leigh Curyer, Chief Executive Officer, commented: "At a time when available physical uranium is extremely tight and expected to continue to be scarce given the long-term supply deficit, this purchase represents a strong opportunity for the Company to bolster its marketing discussions and optimises the optionality of project financing structures under evaluation.  The Company is at a pivotal time, shaping the industry towards transparency, whilst prioritising local community engagement and participation in Saskatchewan and Canada , and providing the globe with clean energy fuel. The transaction is also a significant endorsement of NexGen's approach, role and opportunity in the nuclear sector.  Upon closing of the CDI offering and this strategic uranium purchase, the Company will hold cash and uranium worth over C$930 million and will significantly assist the Company in funding the anticipated capital needs to develop the Rook I Project."

In connection with the Debenture issuance, the Company will enter into an investor rights agreement with MMCap, containing voting alignment, standstill, and sale and transfer restriction covenants.

The Debentures will carry a 9.0% coupon (the "Interest") over a 5-year term. The Debentures will be convertible at the holder's option into Common Shares, at a conversion price (the "Conversion Price") per Common Share of US$10.73 ( C$14.70 per Common Share equivalent incorporating today's exchange rate) representing a 30% premium to the volume-weighted average trading price (the "VWAP") per Common Share on the Toronto Stock Exchange (the "TSX") for the 5-days ending on the day prior to the date of this announcement.

Two-thirds of the Interest (equal to 6% per annum) is payable in cash. One-third of the Interest (equal to 3% per annum) is payable in Common Shares issuable at a price equal to the 20-day VWAP on the New York Stock Exchange (the "NYSE") ending on, and including, the third trading day prior to the date such interest payment is due.

The Company will be entitled, on or after the third anniversary of the date of the issuance of the Debentures, at any time that the 20-day VWAP on the NYSE exceeds 130% of the Conversion Price, to redeem the Debentures at par plus accrued and unpaid Interest.

The Company agreed to issued to MMCap an aggregate of 909,090 Common Shares as an establishment fee in connection with the Debentures, representing 3% of the aggregate principal amount of the Debentures.

Closing of the Purchase is conditional upon the satisfaction of customary closing conditions prior to June 28, 2024 , including stock exchange approvals and third-party approvals required for the transfer of the U ₃ O ₈ and issuance of the Debentures and the completion of definitive documentation.

Farris LLP were legal advisors to NexGen and Wildeboer Dellelce LLP advised MMCap.
