ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

**Differences in United States and Canadian Reporting Practices**

This MD&A has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ in certain material respects from the disclosure requirements promulgated by the Securities and Exchange Commission (the "**SEC**"). For example, the terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are Canadian mining terms as defined in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (the "**CIM**") - *CIM Definition Standards on Mineral Resources and Mineral Reserves*, adopted by the CIM Council, as amended. These definitions differ from the definitions in the disclosure requirements promulgated by the SEC. Accordingly, information contained in this MD&A may not be comparable to similar information made public by U.S. companies reporting pursuant to SEC disclosure requirements. The Company prepares its financial statements, which are referred to in this MD&A, in accordance with International Financial Reporting Standards ("**IFRS**") as issued by the International Accounting Standards Board ("**IASB**"), and the audit of its annual financial statements is subject to auditing and independence standards of the Public Company Accounting Oversight Board in the United States.

**Industry and Economic Factors that May Affect the Business**

The business of mining for minerals involves a high degree of risk. IsoEnergy 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.

As with other companies involved with mineral exploration and development, the Company is subject to cost inflation on exploration drilling and development activities and the Company may experience difficulty and / or delays in securing goods (including spare parts) and services from time-to-time.

The underlying value of the Company's exploration and development assets is dependent upon the existence and economic recovery of Mineral Reserves and is subject to, among others, 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 development assets. The Company does not have any current Mineral Reserves.

In particular, the Company does not generate revenue. As a result, IsoEnergy continues to be dependent on third party financing to continue exploration and development activities on the Company's properties. 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 some of which are described in the section entitled "*Risk Factors*" included below.

**ABOUT ISOENERGY**

IsoEnergy's principal business activity is the acquisition, exploration and development of uranium mineral properties in Canada, the United States, and Australia. The Company's common shares trade on the Toronto Stock Exchange (the "**TSX**") under the trading symbol "ISO", and as of May 5, 2025, trade on the NYSE American LLC (the "**NYSE American**") under the trading symbol "ISOU". The Company exists under the *Business Corporations Act (Ontario).*

On March 20, 2025, the Company completed the consolidation of its issued and outstanding common shares on the basis of one post-consolidation common share for every four pre-consolidation common shares and any fractional shares were rounded down to the nearest whole common share (the "**Share Consolidation**"). The Share Consolidation was implemented in connection with the Company's application to list its common shares on the NYSE American.

As of the date hereof, NexGen Energy Ltd. ("**NexGen**") holds approximately 29.9% of IsoEnergy's outstanding common shares.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

The Company is currently advancing its Larocque East Project in the Athabasca Basin, Saskatchewan, Canada, which is home to the Hurricane deposit ("**Hurricane**" or the "**Hurricane Deposit**"), which has the world's highest grade published Indicated uranium Mineral Resource – 48.6 million pounds of U<sub>3</sub>O<sub>8</sub> at an average grade of 34.5% contained in 63,800 tonnes. The Company also holds a portfolio of permitted, past-producing conventional uranium mines in Utah with toll milling agreements in place with Energy Fuels Inc. ("**Energy Fuels**"). These mines are currently on stand-by, ready for a potential restart as market conditions permit, positioning IsoEnergy as a near-term uranium producer. The Company also has a 50% interest in a joint venture with Purepoint Uranium Group Inc. ("**Purepoint Uranium**"), with respect to a portfolio of exploration projects in the Athabasca Basin (the "**Purepoint Joint Venture**"). The Company's portfolio includes projects and equity holdings in companies with uranium assets at varying stages of exploration and development, providing near, medium, and long-term leverage to rising uranium prices. None of the Company's projects are currently in production and no decisions have been made to bring any of the Company's projects to the production stage.

![](tm2613500d1_ex99-1img002.jpg)

\* Equity holdings include investments in NexGen, Premier American Uranium Inc., Atha Energy Corp., Purepoint Uranium, Future Fuels Inc., Jaguar Uranium Corp., and Orpheus Uranium Ltd. based on market close of April 27, 2026, and Royal Uranium Inc. at its implied fair value on the same date.

**YEAR-TO-DATE 2026 HIGHLIGHTS**

· **Exploration update in the Athabasca Basin and Utah** 

A total of 6,804 metres of drilling in 17 diamond drill holes were completed for the 2026 winter exploration program at the Larocque East Project. The program focused on drilling at the Hurricane Deposit and testing greenfield targets up to three kilometers along the Larocque regional geological-geophysical corridor (the "**Larocque Trend**") (Figure 2). Mineralization was intersected in multiple holes along the South Trend of the Larocque East Project. The 2026 exploration program at the Dorado Project, operated through the Purepoint Joint Venture, was completed in nine holes totalling 5,210 metres which was successful in extending the uranium mineralization at the project.

Mobilization of drilling equipment for the exploration program at the Flatiron Project in Utah has been completed. The drilling program at the Flatiron Project is expected to commence shortly, which plans for the drilling of seven surface rotary holes totalling 11,000 feet.

· **Commencement of key work programs at Tony M** 

The Company completed the mining component of a bulk sample program, which is a critical step in defining the scope and economics of potential future production. The results of the bulk sample program are currently being evaluated, and its results are intended to be used as inputs in other studies planned for 2026. The Tony M Mine remains fully permitted and the results of the completed bulk sample program and planned technical studies are expected to assist in the planning of future mining activities and the determination of a uranium price that may support mining activities at the Tony M Mine.

· **Base Shelf Prospectus** 

The Company filed a final base shelf prospectus (the "**Prospectus**") in Canada and a registration statement in the United States on January 13, 2026. The Prospectus provided for the offering up to $250 million in aggregate of common shares, warrants, units, debt securities, and subscription receipts of the Company in Canada and the United States for a period of 25 months following the filing of the Prospectus.

· **2026 Financing and Concurrent Private Placement** 

On January 27, 2026, the Company closed a "bought deal" financing whereby the Company issued 3,833,410 common shares at a price of $15.00 per share for gross proceeds of approximately $57.5 million (the "**2026 Financing**"). The underwriters were paid a cash commission of 5% of the gross proceeds of the 2026 Financing.

Concurrent with the 2026 Financing, the Company completed a non-brokered private placement whereby the Company issued 1,666,667 common shares to NexGen at a price of $15.00 per share for gross proceeds of approximately $25.0 million (the "**2026 Concurrent Private Placement**"). The 2026 Concurrent Private Placement enabled NexGen to maintain its pro-rata ownership interest in the Company.

· **Launch of At-The-Market equity program** 

On April 17, 2026, the Company entered into an equity distribution agreement (the "**Distribution Agreement**") with a group of agents (the "**Agents**"). The Distribution Agreements allows to Company to distribute up to $50.0 million of its common shares, through the Agents, through the NYSE American or TSX (the "**ATM Program**") at prices related to prevailing market prices or at negotiated prices.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

*<u>Larocque East Project</u>*

*Winter 2026 – Diamond Drilling*

The winter 2026 drilling program focused on testing resource expansion targets at the Hurricane Deposit and testing greenfield targets up to three kilometres east along the Larocque Trend. The Company initially planned for 13 diamond drill holes totalling 5,200 metres and successfully expanded the program to complete 17 diamond drill holes totaling 6,804 metres.

The winter 2026 drilling program focused on resource expansion targets along the North and South Trends (Figure 2). Uranium mineralization was intersected on both trends, which built upon intersections along these two trends from the 2025 exploration programs. Strongly elevated radioactivity was intersected in multiple holes along the South Trend in winter 2026, which emphasizes the growing scale and prospectivity of this trend. This was highlighted by drill hole LE26-248 which returned an average RS-125 spectrometer reading on drill core of 30,050 counts per second ("**cps**") over 1.0 metres within a broader zone of 11,275 cps over 3.5 meters, in the newly interpreted L Fault Zone within the South Trend (Figure 3).

The full suite of geochemical assays and structural interpretations of the winter 2026 drill program, once received, will be used to fully inform drill targets and exploration targets for the summer 2026 drill and exploration programs at Larocque East.

See the Company's press releases dated January 20, 2026 entitled "*IsoEnergy Commences 2026 Winter Drilling Program at the Larocque East Project, Athabasca Basin*" and April 7, 2026 entitled "*IsoEnergy Winter Drilling Intersects Radioactivity in Multiple Holes, Including 30,050 cps over 1.0 Metre, in a Newly Reinterpreted Fault Zone on the South Trend of the Hurricane Deposit*" for additional information regarding the plans and results for the winter 2026 exploration program.

*<u>Dorado Project (Purepoint Joint Venture)</u>*

*Winter 2026 – Drilling*

The winter 2026 drilling program at the Dorado Project, operated by Purepoint Uranium, was completed with nine holes totaling 5,210 metres. The winter 2026 drilling program focused on expanding the high-grade Nova Discovery (Figure 4) and the holes drilled successfully expanded uranium mineralization at the Nova Discovery and extended the geologic contact for a strike length of one kilometre. This was highlighted by drill holes NV26-05 which had an average of 17,700 cps over 1.8 metres and NV26-03A which had an average of 10,600 cps over 1.7 metres. The winter 2026 drill program resulted in establishing a refined targeting framework for continued expansion.

Drilling is planned at the Dorado Project in late June 2026 and an airborne Mobile MagnetoTellurics ("**MobileMT**") survey is planned over the entire Dorado project in the summer of 2026. Once the 2026 exploration programs at Dorado are completed and the full suite of geochemical assays and structural interpretations are received, the results will be used to fully inform future drill targets and exploration targets at the Dorado project.

*<u>Other Canadian projects</u>*

The majority of spending at other Canadian projects was for planning 2026 fieldwork and reporting on 2025 fieldwork at the Matoush project in Quebec. The Company also spent $8,276 to stake several claims extensions along the Larocque East, Hawk, and East Rim projects in the Athabasca Basin.

***United States***

Expenditure on the Company's properties in the United States during the three months ended March 31, 2026 was primarily at the Tony M Mine in Utah.

*<u>Tony M Mine</u>*

The Company completed a bulk sample program, which involved the extraction of approximately 2,100 wet tons of mineralized material. The bulk sample program was executed by the Company using contract mining services provided by GenX Mining Contractors, LLC. The results of the bulk sample program, once fully evaluated, are intended to be inputs in other studies planned for 2026. See the Company's press release dated April 23, 2026 entitled "*IsoEnergy Continues Systematic Drill Testing at Flatiron, Targeting Growth Near Tony M Mine, Utah and Provides Bulk Sample Update"* and "*Outlook*" below for additional information regarding an update of the bulk sample program and the Company's planned 2026 work program at the Tony M Mine, respectively.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

**OUTLOOK**

The Company intends to actively explore all its exploration projects as and when resources permit (other than at the Bulyea River project as discussed below in "*Summary of Quarterly Results*"). The nature and extent of further exploration on any of the Company's properties, however, will depend on the results of completed and ongoing exploration activities, an assessment of the Company's recently acquired properties and the Company's financial resources.

Activities in Canada for 2026 include completing analysis of the results of the 2026 winter exploration program and preparing for drilling in the summer of 2026 at Larocque East, with the continued focus of testing resource expansion potential near the Hurricane Deposit and evaluating greenfield targets along the Larocque Trend, as further outlined in "*Discussion of Operations*" above. Other planned activities in Canada for 2026 include completing geophysical surveys and interpretation at the Evergreen, East Rim, Ranger, Trident, and Hawk projects in the Athabasca Basin, as well as completing geological fieldwork at the Matoush project in Quebec. Remaining activities at the Dorado Project, operated by Purepoint Uranium, include completing a drilling program and a MobileMT survey during the summer of 2026. Once the evaluation of exploration results from the 2026 exploration programs are completed, this information will be used to propose future detailed exploration work.

The Company's planned work program at the Tony M Mine in 2026 includes completing the analysis of the results of the bulk sample program. The Company intends to commence a Preliminary Economic Assessment ("**PEA**") in 2026, incorporating the results from the bulk sample program. The PEA will provide an incentive uranium price for production and a basis for advancing detailed mine planning, finalizing potential restart sequencing, and assessing possible timing of a potential production decision. Activities in the US in 2026 also include completing the 2026 drilling program at the Flatiron Project and the 2026 exploration programs at the Daneros, and Sage Plain projects, in Utah. The target area of the planned drilling at the Flatiron Project is intended to follow up on the three drill holes completed in 2025.

The Company intends to complete internal technical studies on several non-material properties in 2026.

**SELECTED FINANCIAL INFORMATION**

**Financial Position**

The following financial data is derived from and should be read in conjunction with the Interim Financial Statements and the Annual Financial Statements. As an exploration stage company, IsoEnergy does not have revenues.

(1) Adjusted working capital is a non-IFRS financial measure, as discussed below, and is defined as current
assets less current liabilities, excluding flow-though share premium liabilities and convertible debenture liabilities.

In the three months ended March 31, 2026, the Company capitalized $7,172,099 of exploration and evaluation costs, before movements in foreign exchange rates, as further described in "*Discussion of Operations*" above. Total assets increased primarily due to $57,501,150 raised in the 2026 Financing and $25,000,005 raised in the January 2026 Concurrent Private Placement, with associated share issuance costs of $4,022,591. Total assets also increased from the receipt of $4,498,560 of common shares of Jaguar Uranium Corp. ("**Jaguar Uranium**") as the remaining consideration pursuant to the sale of the Company's Argentina assets that was completed in July 2024. Increases to total assets were partially offset by a decrease in the fair value of marketable securities of $9,857,333 during the three months ended March 31, 2026.

Current liabilities as at March 31, 2026, include a flow-through share premium liability of $2,909,206 relating to the February 2025 Financing (as defined herein). Accounts payable and accrued liabilities decreased by $338,873 during the three months ended March 31, 2026 mostly due to the completion of the 2026 winter exploration program at Larocque East. The fair value of the US$4 million in principle of unsecured convertible debentures issued on December 6, 2022 (the "**2022 Debentures**") increased by $574,096 during the three months ended March 31, 2026. Adjusted working capital increased during the three months ended March 31, 2026 mainly due to the 2026 Financing and 2026 Concurrent Private Placement.

<u>Proposed Transaction</u>

On October 12, 2025, the Company and Toro Energy Limited ("**Toro Energy**") entered into a scheme implementation deed (the "**SID**") pursuant to which IsoEnergy, through one of its wholly owned subsidiaries, has agreed to acquire all of the issued and outstanding ordinary shares of Toro Energy (the "**Toro Energy Shares**") by way of a scheme of arrangement under Australia's Corporations Act 2001 (Cth) (the "**Toro Scheme**"). Toro Energy is an Australian Securities Exchange ("**ASX**") listed company that owns 100% of the Wiluna uranium project in Western Australia, Australia, as well as other exploration stage uranium properties in Australia.

Under the terms of the SID, shareholders of Toro Energy (the "**Toro Energy Shareholders**") will receive 0.036 of a common share of IsoEnergy for each Toro Energy Share. Completion of the Toro Scheme is subject to various conditions, including but not limited to: approval of Toro Energy Shareholders; court approval; applicable regulatory approvals, including approval of the ASX, TSX, and NYSE American; and an independent expert concluding and continuing to conclude that the Toro Scheme is in the best interests of Toro Energy Shareholders. Following the completion of the Toro Scheme, the IsoEnergy common shares will continue to trade on the TSX and NYSE American and the Toro Energy Shares will be delisted from the ASX. The Toro Scheme is expected to close in the first half of 2026.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

Subsequent to March 31, 2026, IsoEnergy agreed to provide an unsecured bridge loan of up to AUD$2,000,000 million to Toro Energy (the "**Loan Agreement**"), with an interest rate of 10% per annum up to and including June 30, 2026, increasing to 15% per annum thereafter. The Loan Agreement has a maturity date of December 31, 2026, or earlier under certain circumstances. The principal amount and accrued interest on the Loan Agreement can be prepaid by Toro Energy, in its sole discretion, prior to the maturity date. Drawdowns pursuant to the Loan Agreement will be utilized for working capital and to satisfy other obligations of Toro Energy through to the closing of the SID. On May 6, 2026, Toro Energy drew down AUD$750,000 under the Loan Agreement.

***Three months ended March 31, 2026***

During the three months ended March 31, 2026, the Company recorded a net loss of $1,502,775, compared to net income of $5,105,615 in the three months ended March 31, 2025. The main driver of the difference between the two periods was a gain on disposal of $4,498,560 recorded in the current period from the receipt of the remaining consideration from the sale of the Argentina reporting segment, which was accounted for as a contingent asset until it was received, compared to $10,369,031 recorded in the prior period relating to the sale of the Mountain Lake property. The decrease from net income in the prior period to a net loss in the current period was also due to an increase in general and administrative costs of $991,723, as further described below. Other factors causing the difference between the two periods are further described below.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

*<u>General and administrative costs</u>*

Share-based compensation was $2,624,482 in the three months ended March 31, 2026, compared to $1,945,839 in the three months ended March 31, 2025. The share-based compensation expense is a non-cash charge based on the Black-Scholes value of stock options, calculated using the graded vesting method. Stock options granted to directors, consultants and employees typically vest in three tranches – 1/3 immediately, 1/3 on the first anniversary of the grant date, and the remaining 1/3 on the second anniversary of the grant date, with the corresponding share-based compensation expense being recognized over this period. The increase in the current period was primarily due to a higher number of stock options granted during the three months ended March 31, 2026 compared to the prior period.

Administrative salaries, contractor and directors' fees increased slightly from the prior period primarily due to the addition of the Vice President, Strategy and Commercial in the three months ended December 31, 2025.

Investor relations expenses relate primarily to costs incurred in communicating with existing and potential shareholders, conferences and marketing. The increase in the current period is primarily due to additional marketing activities in the United States, Europe, and Asia.

Office and administrative expenses primarily consist of office operating costs and other general administrative costs. Office and administrative expenses were similar in both periods.

Professional fees were lower than the prior period mainly due to legal and advisory fees related to the terminated transaction with Anfield Energy Inc. during the three months ended March 31, 2025.

Travel expenses primarily relate to travel and accommodation costs for conferences, business development activities, public relations activities, and general corporate purposes. Travel costs were similar in both periods.

Public company costs consist primarily of costs associated with the Company's continuous disclosure obligations, listing fees, directors and officers insurance, transfer agent costs, press releases and other shareholder communications. The increase in public company costs is primarily due to the additional costs of sustaining a listing on the NYSE American, including the amortization of the premium for additional Director and Officer insurance.

*<u>Other items</u>*

Interest expense on the Debentures (as defined herein) was $137,187 in the three months ended March 31, 2026, which decreased from $262,550 in the three months ended March 31, 2025. The 2022 Debentures bear interest of 10% per annum and is payable, with a combination of cash and common shares of the Company, on June 30 and December 31. The decrease is primarily due to the US$6 million principal of unsecured convertible debentures issued on August 18, 2020 (the "**2020 Debentures**") being fully converted by August 1, 2025.

The fair value of the 2022 Debentures on March 31, 2026 was $6,004,955 compared to $5,430,859 on December 31, 2025. The increase in fair value includes $573,612 recorded in the statement of income and a fair value increase attributable to the change in credit risk of $484 included in other comprehensive income (loss). The 2022 Debentures are classified as measured at fair value through profit and loss. In accordance with IFRS 9 – Financial Instruments, the part of a fair value change due to an entity's own credit risk is presented in other comprehensive income (loss). As of March 31, 2026, the time to maturity of the 2022 Debentures was 1.7 years.

Foreign exchange gain was $149,395 in the three months ended March 31, 2026, compared to a gain of $6,919 in the three months ended March 31, 2025, and mainly relates to exchange movements on an increased cash balance denominated in United States dollars held by the Company.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

Other income was $19,239 in the three months ended March 31, 2026, compared to $431,921 in the three months ended March 31, 2025. This primarily relates to timber sales earned from the Company's operations in the US in the prior period, of which no such sales occurred in the current period.

The Company records a deferred tax recovery or expense which is comprised of a recovery on losses or expense on gains recognized in the period and, when applicable, the release of flow-through share premium liability which is offset by the renunciation of flow-through share expenditures to shareholders. In the three months ended March 31, 2026, this resulted in an expense of $633,051, compared to an expense of $830,871 in the three months ended March 31, 2026. The decrease in expense is mostly due to a lower gain on sale compared to the prior period.

---

(1) Net income (loss) per share amounts in the three latter quarters presented are retroactively restated on a post-Share Consolidation
basis. Refer to the discussion on the Share Consolidation above in "*About IsoEnergy* ".

(2) Loss from discontinued operations relates to the Argentina reporting segment which was disposed of during the three months ended September 30,
2024. IsoEnergy does not derive any revenue from its operations. Its primary focus is the acquisition, exploration and development of mineral properties. As a result, the income (loss) per period has fluctuated depending on the Company's activity level and periodic variances in certain items. Quarterly periods are therefore not comparable. As part of the Company's strategy to evaluate additional Merger and Acquisition ("**M&A**") opportunities throughout the life cycle of mineral properties, the Company may incur gains or losses related to such transactions or incur expenses for M&A opportunities that do not materialize. In the three months ended March 31, 2026, a gain of $4,498,560 was recorded on the receipt of common shares of Jaguar Uranium as the remaining consideration pursuant to the sale of the Argentina reporting segment; in the three months December 31, 2025, a gain of $2,250,000 was recorded on the receipt of common shares of Future Fuels as the remaining consideration pursuant to the sale of the Mountain Lake property; in the three months ended June 30, 2025, a gain of $820,394 was recorded on the sale of certain of the Company's royalty assets; in the three months ended March 31, 2025, a $10,369,031 gain was recorded on the sale of the Mountain Lake property; in the three months ended December 31, 2024, a loss of $25,616,241 was recorded from the contribution of exploration and evaluation assets to the Purepoint Joint Venture; and in the three months ended September 30, 2024, a $5,300,611 gain was recorded on the disposal of its Argentina assets.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

The Company also assesses for indicators of impairment on its property and equipment and exploration and evaluation assets quarterly, as required by the relevant IFRS. If such indicators are identified, an analysis to determine its recoverable value is performed and if such amount is lower than the carrying value, a loss is recognized for the difference. In the three months ended December 31, 2025, the Company expected to not currently continue exploration work at its Bulyea River property and recorded a write-down of $935,814. In the three months ended December 31, 2024, the Company identified indicators of impairment on certain exploration and evaluation assets located in the Athabasca Basin primarily as a result of the loss on the formation of the Purepoint Joint Venture and recorded a write-down of $14,342,736.

In the third quarter of 2020, the Company issued the 2020 Debentures and in the fourth quarter of 2022 issued the 2022 Debentures, both of which were and are, respectively, accounted for as measured at fair value through profit and loss, which has resulted in a gain on the revaluation of the Debentures in the three months ended September 30, 2024, three months ended December 31, 2024, three months ended June 30, 2025, three months ended September 30, 2025, three months ended December 31, 2025, and losses in every other period.

**LIQUIDITY AND CAPITAL RESOURCES**

IsoEnergy has no revenue-producing operations, earns only minimal interest income on cash, and is expected to have recurring operating losses. As of March 31, 2026, the Company had an accumulated deficit of $105,174,420.

During the three months ended March 31, 2026, the Company utilized cash on hand to invest $6,427,655 (net of changes in accounts payable) in exploration and evaluation assets, $2,634,898 for expenditure on its corporate and business development activities, including movements in working capital, and spent $3,931,793 (net of proceeds from disposals) to invest in common shares and/or warrants of marketable securities.

During the three months ended March 31, 2026, the Company received $78,478,564 in net proceeds from the 2026 Financing and the 2026 Concurrent Private Placement.

As of the date of this MD&A, the Company has approximately $128.5 million in cash, $53.1 million in marketable securities and $182.5 million in adjusted working capital.

The Company has fully funded its global exploration and pre-development activities, as well as any corporate initiatives and general working capital, up to the end of December 31, 2026. This includes costs associated with completing the Toro Scheme and funding future approved expenditures on the properties to be acquired from Toro Energy. The ability of the Company to continue as a going concern is dependent on its ability to obtain financing and achieve future profitable operations.

Should the Company require additional financing under its Prospectus or otherwise, Management will determine whether to accept any offer to finance, weighing such factors as the financing terms, the results of exploration programs and technical studies, the Company's share price at the time and current market conditions, among others.

Circumstances that could impair the Company's ability to raise additional funds include general economic conditions, the price of uranium and certain other factors set forth under "*Risk Factors*" below and above under "*Industry and Economic Factors that May Affect the Business*". A failure to obtain financing as and when required, could require the Company to reduce its exploration and corporate activity levels.

**Use of Proceeds**

On February 9, 2024, the Company completed a brokered "bought-deal" private placement for gross proceeds of $23.0 million (the "**February 2024 Private Placement**"). The proceeds from the February 2024 Private Placement were required to be and were spent on eligible "Canadian exploration expenses" that qualify as "flow-through critical mineral mining expenditures" by December 31, 2025.

On February 28, 2025, the Company completed a "bought deal" financing whereby the Company issued 1,333,825 "flow-through" common shares<sup>(1)</sup> at a price of $15.00 per share, for gross proceeds of approximately $20.0 million (the "**February 2025 Financing**"). Concurrent with the February 2025 Financing, the Company completed a non-brokered private placement whereby the Company issued 625,000 common shares<sup>(1)</sup> to NexGen for gross proceeds of approximately $6.3 million (the "**2025 Concurrent Private Placement**"). On June 24, 2025, the Company closed a "bought deal" financing whereby the Company issued 5,121,500 common shares at a price of $10.00 per share for gross proceeds of approximately $51.2 million (the "**June 2025 Financing**"). The proceeds from the February 2025 Financing are required to be spent on eligible "Canadian exploration expenses" that qualify as "flow-through critical mineral mining expenditures" (in each case as defined in the Income Tax Act (Canada) (the "**Tax Act**")) by December 31, 2026 and the Company was required to and did renounce the full amount of the gross proceeds of the financing to the subscribers of the flow-through shares no later than December 31, 2025. The proceeds of 2025 Concurrent Private Placement were to be used for other non-qualifying expenditures on the exploration of the Company's Canadian properties, costs associated with the listing on the NYSE American, and for working capital and general corporate purposes. The proceeds of the June 2025 Financing are expected to be used to fund continued development and further exploration of the Company's mineral properties, and for general corporate purposes.

On January 27, 2026, the Company received total gross proceeds of $82.5 million from the January 2026 Financing and 2026 Concurrent Private Placement. The proceeds of these two financings are expected to be used to fund continued development and further exploration of the Company's mineral properties, corporate development activities and investments, and for general corporate purposes.

The balance remaining in treasury are intended to be applied towards the intended uses of the subsequent financings described above. The Company's properties are in good standing with applicable governmental authorities. Other than the contractually agreed upon exploration budget in 2026 for the Purepoint Joint Venture, the Company does not have any contractually imposed expenditure requirements.

The Company has not paid any dividends and management does not expect that this will change in the near future. Working capital is mainly held in cash, cash deposits available on short-term demand, and marketable securities, all of which are highly liquid.

**COMMITMENTS AND CONTINGENCIES**

The Company's significant undiscounted commitments at March 31, 2026 are as follows. The 2022 Debentures are classified as a current liability, however the counterparty conversion option allows the principal to be converted to common shares.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

The Company expects to utilize cash and cash equivalents on hand to settle the above noted commitments and contingencies, should any of the contingencies materialize.

**Flow-through funding commitments**

The premium received for a "flow-through share" (as defined in the Tax Act), which is the consideration received for the share in excess of the market price of the share, is recorded as a flow-through share premium liability. This liability is subsequently reduced when the required exploration expenditures are made, on a pro rata basis, and accordingly, a recovery of flow-through premium is then recorded as a reduction in the deferred tax expense to the extent that deferred income tax assets are available.

As of March 31, 2026, the Company is obligated to spend $7,273,014 on eligible exploration expenditures by December 31, 2026 related to the February 2025 Financing.

**Contingent payment obligations**

The Company has an obligation to make a contingent payment of $500,000 related to the acquisition of the West Newcastle Range, Teddy Mountain and Ardmore East Projects, if either of the following milestones are met by 2030:

· a NI 43-101 compliant Mineral Resource estimate
for the West Newcastle Range and Teddy Mountain Projects is prepared where the Mineral Resource estimate is greater than or equal to 6.0
million pounds of U₃O₈; or

· with respect to the Ardmore East Project, the
Mineral Resources estimate is greater than or equal to 6.0 million pounds of U₃O₈ equivalent.

**Royalties and Environmental Obligations**

In addition to applicable federal, provincial/state and municipal severance taxes, duties and advance royalties, the Company's exploration and evaluation properties are subject to certain royalties, which may or may not be payable in future, depending on whether revenue is derived from the claims or leases to which these royalties are applicable.

The Company's mining and exploration activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and generally becoming more restrictive. The Company believes its operations are materially in compliance with all applicable laws and regulations. The Company has made, and expects to make in the future, expenditures to comply with such laws and regulations.

**Contractual arrangements**

The purchase agreement for the Bulyea River property, which closed on June 28, 2024, includes a provision for the return of the Bulyea River property to Critical Path Minerals Corp. ("**Critical Path Minerals**"), if the Company does not or chooses to not make the following payments to Critical Path Minerals by the following dates:

· On or before the 2<sup>nd</sup> anniversary of
the closing date of sale: $300,000 in cash or common shares or a combination thereof, at the election of the Company; and

· On or before the 3<sup>rd</sup> anniversary of
the closing date of sale: $350,000 in cash or common shares or a combination thereof, at the election of the Company.

The Company also agreed to:

· Incur minimum expenditures of $2,000,000 within
36 months of the closing date of sale; and

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

shares or a combination thereof, at the election of the Company

**NON-IFRS FINANCIAL MEASURES**

Working capital and adjusted working capital are non-IFRS financial measures included in this MD&A, as discussed below. We believe that working capital and adjusted working capital, in addition to conventional measures prepared in accordance with IFRS, provide investors with an improved ability to evaluate the underlying financial position of the Company. These non-IFRS financial measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. This financial measure does not have any standardized meaning prescribed under IFRS and therefore may not be comparable to those of other issuers.

|:---|:---|
| Current assets | $185193085 |
| Current liabilities | (10853370) |

**CRITICAL ACCOUNTING JUDGMENTS, ESTIMATES AND ASSUMPTIONS**

The preparation of the Interim Financial Statements requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, and contingent liabilities at the date of the Interim Financial Statements and the reported amounts of revenues and expenses during the reporting period. 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 in the circumstances. Uncertainty about these judgments, estimates and assumptions could result in outcomes that require a material adjustment to the carrying amount of the asset or liability affected in future periods. Information about significant areas of judgement, estimation uncertainty and assumptions considered by management in preparing the Interim Financial Statements are the same as described in the Annual Financial Statements.

**CHANGES IN ACCOUNTING POLICIES INCLUDING INITIAL ADOPTION**

The Interim Financial Statements were prepared in accordance with IAS 34 and its interpretations adopted by the IASB, and follow the same accounting policies and methods as described in the Annual Financial Statements.

The following standard has been issued and is effective:

**Amendments to IFRS 9 and IFRS 7 – Classification and Measurement of Financial Instruments**

In May 2024, the IASB issued *'Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7)*'. The amendments clarify the date of recognition and derecognition of some financial assets and financial liabilities, with a new exception that permits companies to elect to derecognize certain financial liabilities settled via electronic payment systems earlier than the settlement date. The amendments apply for annual reporting periods beginning on or after January 1, 2026, and are applied retrospectively. There were no changes to the Interim Financial Statements from adopting these amendments.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

The following new standard has been issued and is not yet effective:

**IFRS 18 – Presentation and Disclosure in Financial Statements**

The IASB has issued IFRS 18 – *Presentation and Disclosure in Financial Statements* ("**IFRS 18**"), which replaces IAS 1 – *Presentation of Financial Statements*. IFRS 18 introduces new requirements for the presentation of financial performance, including revised categories in the statements of loss, enhanced disclosures on management-defined performance measures, and greater consistency in financial statement presentation. The standard is effective for annual reporting periods beginning on or after January 1, 2027 and applies retrospectively, with early adoption permitted.

The Company has not early adopted IFRS 18 and continues to evaluate the impact of the forthcoming standard in preparing the Interim Financial Statements.

**CAPITAL MANAGEMENT** **AND RESOURCES**

The Company manages its capital structure, defined as total equity plus debt, and adjusts it, based on the funds available to the Company, in order to support the acquisition, exploration and evaluation of assets. The Board does not impose 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 types of funding alternatives, including equity, debt and other means and is dependent on third party financing. 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 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.

Management reviews its capital management approach on an on-going basis and believes that this approach, given the relative size of the Company, is reasonable. 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.

**FINANCIAL INSTRUMENTS**

The Company's financial instruments consist of cash and cash equivalents, accounts receivable, marketable securities, accounts payable and accrued liabilities, and convertible debentures.

**Fair Value Measurement**

The Company classifies the fair value of financial instruments according to the following hierarchy based on the amount of observable inputs used to value the instrument:

· Level 1 – quoted prices in active markets
for identical assets or liabilities.

· Level 2 – inputs other than quoted prices
included in Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from
prices).

· Level 3 – inputs for the asset or liability
that are not based on observable market data.

The fair values of the Company's cash and cash equivalents, accounts receivable, and accounts payable and accrued liabilities approximate their carrying value, due to their short-term maturities or liquidity.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

The 2022 Debentures are re-measured at fair value at each reporting date with any change in fair value recognized in profit or loss, except for the change in fair value that is attributable to change in credit risk, which is presented in other comprehensive income (loss). The 2022 Debentures are classified as Level 2.

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). The common shares included in marketable securities are Level 1, except for the common shares of privately held marketable securities, which are Level 3 and their fair value is primarily based on the price of their most recent share issuances. The warrants included in marketable securities are Level 2. During the three months ended March 31, 2026, Jaguar Uranium and Verdera Energy Corp. completed public listings. As a result, the Company transferred its common shares held in these entities from Level 3 to Level 1. The fair value transferred is measured at the share price at the time of the public listing of each entity.

**Financial instrument risk exposure**

As of March 31, 2026, the Company's financial instrument risk exposure and the impact thereof on the Company's financial instruments are summarized below:

**(a)** **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. As at March 31, 2026, the Company has cash and cash equivalents on deposit with large banks in Canada, the United States, and Australia. Credit risk is concentrated as a significant amount of the Company's cash and cash equivalents is held at a Canadian financial institution. Management believes the risk of loss to be remote.

The Company's accounts receivable mostly consists of input tax credits receivable from the Governments of Canada and Australia and amounts receivable from related parties. Accordingly, the Company does not believe it is subject to significant credit risk.

**(b) Liquidity Risk**

Liquidity risk is the risk that an entity will encounter difficulty in raising funds to meet its obligations under financial instruments. The Company manages liquidity risk by maintaining sufficient cash balances that are accessible on deposit or on short-term notice. Liquidity requirements are managed based on expected cash flows to ensure that there is sufficient capital to meet short-term obligations. As at March 31, 2026, the Company had an adjusted working capital balance of $183,253,876, including cash and cash equivalents of $130,537,804.

**(c) Market Risk**

Market risk is the risk of loss that may arise from changes in market factors such as interest rates, foreign exchange rates and commodity and equity prices.

**(i)** **Interest Rate Risk** 

Interest rate risk is the risk that the future cash flows from a financial instrument will fluctuate due to changes in market interest rates. The Company holds its cash and cash equivalents 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 and cash equivalent balances as of March 31, 2026. The interest on the 2022 Debentures is fixed and not subject to market fluctuations.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

**(ii)** **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 of movements in individual equity prices or general movements in the level of the stock market on the Company's financial performance. Commodity price risk is defined as the potential adverse impact of commodity price movements and volatilities on financial performance and economic value. Future declines in commodity prices may impact the valuation of long-lived assets. The Company closely monitors the commodity prices of uranium, individual equity movements, and the stock market. The Company holds marketable securities which are subject to equity price risk.

**(iii)** **Foreign Currency Risk** 

The Company enters into transactions denominated in foreign currencies from time-to-time and in addition to Canada, the Company operates in the United States and Australia, and is therefore exposed to foreign exchange risk arising from transactions denominated in foreign currencies. Foreign exchange risk arises when future commercial transactions or recognized assets or liabilities are denominated in a currency that is not the Company's functional currency. Consequently, fluctuations of the Canadian dollar in relation to other currencies impact the fair value of financial assets, liabilities and operating results. Financial instruments subject to foreign currency risk include US dollar and Australian dollar denominated cash, US dollar and Australian dollar accounts receivable, US dollar and Australian dollar marketable securities, US dollar and Australian dollar accounts payable and accrued liabilities, and the 2022 Debentures. The Company maintains Canadian, US and Australian dollar bank accounts.

The Company is exposed to foreign exchange risk on its US dollar denominated cash, accounts payable and accrued liabilities, accounts receivable, marketable securities and 2022 Debentures. At its maturity date, the principal amount of the 2022 Debentures is due in full, and prior to then at a premium upon the occurrence of certain events, including a change of control. The Company holds sufficient US dollars to make all cash interest payments due under the 2022 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 2022 Debentures more costly to repay.

A 5% change in the Canadian/US dollar exchange rate can result in a net increase or decrease in the Company's US dollar denominated financial instruments of $675,540 that would flow through the consolidated statement of income and comprehensive (loss) income.

The Company is exposed to foreign exchange risk on its Australian dollar denominated cash, accounts receivable, marketable securities, and accounts payable and accrued liabilities. Accordingly, the Company is subject to risks associated with fluctuations in the Canadian/Australian dollar exchange rate that may impact on its operating results.

A 5% change in the Canadian/Australian dollar exchange rate can result in a net increase or decrease in the Company's Australian dollar denominated financial instruments by $241,327 that would flow through consolidated statement of income and comprehensive (loss) income.

**RISK FACTORS**

The operations of the Company are speculative due to the high-risk nature of its business which is the exploration and development of mineral properties.

**Regulatory Factors and International Trade Restrictions**

The international uranium industry, including the supply of uranium concentrates, is relatively small, highly competitive and heavily regulated. Worldwide demand for uranium is directly tied to the demand for electricity produced by the nuclear power industry, which is also subject to extensive government regulation and policies. The development of mines and related facilities is contingent upon governmental approvals that are complex and time consuming to obtain and which, depending upon the location of the project, involve multiple governmental agencies. The duration and success of such approvals are subject to many variables outside of the Company's control. Any significant delays in obtaining or renewing such permits or licences in the future could have a material adverse effect on the Company.

In addition, the international marketing and trade of uranium is subject to potential changes in governmental policies, regulatory requirements and international trade restrictions (including trade agreements, customs, duties and taxes), which are beyond the control of the Company. Changes in regulatory requirements, customs, duties or taxes may affect the supply of uranium to the United States and Europe, which are currently the largest consumption markets for uranium in the world, as well as the future of supply to developing markets, such as China and India.

The supply of uranium is, to some extent, impeded by a number of international trade agreements and policies. These and any similar future agreements, governmental legislation, policies or trade restrictions are beyond the Company's control and may affect the supply of uranium available in the United States, Europe and Asia, the world's largest markets for uranium. If the Company achieves commercial production but is unable to supply uranium to important markets in the United States or Europe, its business, financial condition and results of operations may be materially adversely affected. In addition, there can be no assurance that governments will not enact legislation or take other actions that restricts who can buy or supply uranium, which may have a material adverse effect on the price of uranium and the Company's financial condition and results of operations.

In particular, pursuant to an executive order, the United States has enacted significant new import tariffs on certain trade and transactions with Canada and other trading partners. Canada has enacted retaliatory import tariffs on certain trade and transactions from the United States. There is significant uncertainty surrounding further changes in governmental policy, particularly with respect to such trade policies, treaties and tariffs. These developments, and any similar further changes in governmental policy, may have a material adverse effect on global economic conditions and financial markets. The full economic impact of any such changes in governmental policy on the Company remains uncertain and is dependent on the severity and duration of the tariffs and any other measures imposed which, if prolonged, could increase costs and decrease demand for any minerals that may be extracted by the Company.

For a comprehensive list of the risks and uncertainties facing the Company, please see *"Risk Factors"* in the Company's AIF and the *"Industry and Economic Factors that May Affect the Business"* included above in the Overall Performance section of this MD&A. These are not the only risks and uncertainties that the Company 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. Further risk factors are discussed in more detail in the Company's AIF.

Significant variances in the geographic disclosure above are discussed in further detail in "*Discussion of Operations*" and "*Financial Position*".

**DISCLOSURE CONTROLS AND INTERNAL CONTROL OVER FINANCIAL REPORTING**

**Disclosure Controls and Procedures**

Disclosure controls and procedures are designed to provide reasonable assurance that material information is gathered and reported to management, including the Chief Executive Officer ("**CEO**") and Chief Financial Officer ("**CFO**"), as appropriate to allow for timely decisions about public disclosures. The Company's management, with the participation of its CEO and CFO, has evaluated the effectiveness of the design and operation of the Company's disclosure controls and procedures, as defined in the rules of the SEC and Canadian Securities Administrators. Based on the results of that evaluation, the Company's CEO and CFO have concluded that, as of March 31, 2026, the Company's disclosure controls and procedures framework provides reasonable assurance that the information required to be disclosed by the Company in reports it files is recorded, processed, summarized and reported, within the appropriate time periods and is accumulated and communicated to management, including the CEO and CFO, as appropriate to allow timely decisions regarding required information to be disclosed. Internal control over financial reporting ("**ICOFR**") are part of disclosure controls and procedures as they related to the production of financial statements in accordance with IFRS.

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

**Changes in Internal Control over Financial Reporting**

Management, including the CEO and CFO, has evaluated the Company's ICOFR to determine whether any changes occurred during the period that have materially affected, or are reasonably likely to materially affect, the Company's ICOFR. During the three months ended March 31, 2026 there have been no significant changes in ICOFR that have materially affected, or are reasonably likely to materially affect, the Company's ICOFR. Under the supervision and with the participation of management, including the CEO and CFO, management will continue to monitor and evaluate the design and effectiveness of its ICOFR and disclosure controls and procedures, and may make modifications from time to time as considered necessary.

**Limitations of Controls and Procedures**

The Company's management, including the CEO and CFO, believe that any control system, 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.

**NOTE REGARDING FORWARD-LOOKING INFORMATION**

*This MD&A contains "forward-looking information" and "forward-looking statements" within the meaning of applicable Canadian securities legislation and US securities laws (collectively, "**forward-looking information**"). Forward-looking information includes, but is not limited to, statements with respect to the activities, events or developments that the Company expects or anticipates will or may occur in the future, including, without limitation, the closing of the Toro Scheme; the potential issuance of additional securities under the Prospectus or otherwise, certain statements relating to "flow-through shares" as defined in the Tax Act, and the tax considerations relating thereto, the Company's planned exploration and development activities and the anticipated results of ongoing and future exploration and development activities; capital expenditures and proposed work programs at the Company's properties, the potential for, results of and anticipated timing of commencement of potential future commercial production at IsoEnergy's properties, including expectations with respect to any permitting, development or other work that may be required to bring any of the projects into development or production. 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 may also be deemed forward-looking information as they involve estimates of the mineralization that will be encountered if a mineral deposit is developed and mined.*

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

*Such forward-looking information and statements are based on numerous assumptions, including material assumptions and estimates related to the below factors that, while the Company considers them reasonable as of the date of this MD&A, they are inherently subject to significant business, economic and competitive uncertainties and contingencies. Such assumptions include among others, that the results of planned exploration activities are completed as anticipated, that the results of the planned exploration activities are as anticipated, that the anticipated cost of planned exploration activities are as anticipated, that the Company will be able to execute its strategy as expected, that new mining techniques will have beneficial applications as expected and be available for use by the Company, continued engagement and collaboration with the communities and stakeholders, that general business and economic conditions will not change in a material adverse manner, including the price of uranium, that financing will be available if and when needed and on reasonable terms, and that third party contractors, equipment and supplies and governmental and other approvals required to conduct the Company's planned exploration activities will be available on reasonable terms and in a timely 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.*

*Forward-looking information and statements also involve known and unknown risks and uncertainties and other factors, which may cause actual events or results in future periods to differ materially from any projections of future events or results expressed or implied by such forward-looking information or statements, including, among others: negative operating cash flow and dependence on third party financing, uncertainty of additional financing, risks associated with the uncertainty of exploration results and estimates and that the Mineral Resource potential will be achieved on exploration projects, the Company having no known Mineral Reserves, resources may not be converted to reserves, the limited operating history of the Company, the influence of a large shareholder, alternative sources of energy and uranium prices, aboriginal title and consultation issues, reliance on key management and other personnel, actual results of exploration activities being different than anticipated, changes in exploration programs based upon results, availability of third party contractors, availability of equipment and supplies, failure of equipment to operate as anticipated; accidents, effects of weather and other natural phenomena and other risks associated with the mineral exploration industry, environmental risks, changes in laws and regulations, community relations and delays in obtaining governmental or other approvals and the risk factors with respect to the Company set out in the AIF and the Company's other filings with the Canadian and US securities regulators and available under IsoEnergy's profile on SEDAR+ at <u>www.sedarplus.ca</u> and EDGAR at <u>www.sec.gov</u>.*

*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 implied by forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking information and statements will prove to be accurate, as actual results and future events could differ materially from those anticipated, estimated or intended. Accordingly, readers should not place undue reliance on forward-looking statements or information. The Company undertakes no obligation to update or reissue forward-looking information as a result of new information or events except as required by applicable securities laws.*

**HISTORICAL ESTIMATES**

*Each of the Mineral Resource estimates contained in this MD&A, except for the Larocque East Project and Tony M Mine, are considered to be "historical estimates" as defined under NI 43-101, and have been sourced as follows:*

· *Daneros Mine: Reported by Energy Fuels in a technical report entitled "Updated Report on the Daneros Mine Project, San Juan County, Utah, U.S.A.", prepared by Douglas C. Peters, C. P. G., of Peters Geosciences, dated March 2, 2018;* 

· *Sage Plain Project: Reported by Energy Fuels in a technical report entitled "Updated Technical Report on Sage Plain Project (Including the Calliham Mine)", prepared by Douglas C. Peters, CPG of Peters Geosciences, dated March 18, 2015;* 

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

· *Coles Hill: Reported by Virginia Uranium Holdings Inc. in a technical report entitled "NI43-101 preliminary economic assessment update (revised)", prepared by John I Kyle of Lyntek Incorporated dated August 19, 2013;* 

· *Dieter Lake: Dated 2006 and reported by Fission Energy Corp. in a company report entitled "Technical Report on the Dieter Lake Property, Quebec, Canada" dated October 7, 2011;* 

· *Matoush: Dated December 7, 2012 and reported by Strateco Resources Inc. in a press release dated December 7, 2012;* 

· *Ben Lomond: Dated as of 1982, and reported by Mega Uranium Ltd. in a company report entitled "Technical Report on the Mining Leases Covering the Ben Lomond Uranium-Molybdenum Deposit Queensland, Australia" dated July 16, 2005; and* 

· *Milo Project: Reported by Gmb Resources Ltd. in a scoping study entitled "Milo Project Scoping Study" prepared by Peter Owens and Basile Dean of Mining One Consultants, dated March 6, 2013.* 

*In each instance, the historical estimate is reported using the categories of Mineral Resources and Mineral Reserves as defined by the Canadian Institute CIM Definition Standards for Mineral Reserves, and Mineral Reserves at that time, and these "historical estimates" are not considered by IsoEnergy to be current. In each instance, the reliability of the historical estimate is considered reasonable, but a Qualified Person has not done sufficient work to classify the historical estimate as a current Mineral Resource, and IsoEnergy is not treating the historical estimate as a current Mineral Resource. The historical information provides an indication of the exploration potential of the properties but may not be representative of expected results.*

*For the Daneros Mine, as disclosed in the above noted technical report, the historical estimate was prepared by Energy Fuels using a wireframe model of the mineralized zone based on an outside bound of a 0.05% eU<sub>3</sub>O<sub>8</sub> grade cutoff at a minimum thickness of 1 foot. Surface drilling would need to be conducted to confirm resources and connectivity of resources in order to verify the Daneros historical estimate as a current Mineral Resource.*

*For the Sage Plain Project, as disclosed in the above noted technical report, the historical estimate was prepared by Peters Geosciences using a modified polygonal method. An exploration program would need to be conducted, including twinning of historical drill holes, in order to verify the Sage Plain historical estimate as a current Mineral Resource.*

*For the Coles Hill Project, as disclosed in the above noted revised preliminary economic assessment, the historical estimated was prepared by John I Kyle of Lyntek Incorporated. Twinning of a selection of certain holes would need to be completed along with updating of mining, processing and certain cost estimates in order to verify the Coles Hill Project historical resource estimate as a current Mineral Resource estimate.*

*For Dieter Lake, as disclosed in the above noted technical report, the historical estimate was prepared by Davis & Guo using the Thiessen (Voronoi) polygon method. Data constraints used were 200 ppm, 500 ppm, and 1000ppm U<sub>3</sub>O<sub>8</sub> over a minimum of 1 metre thickness. Polygons created had radii of 200 metres. A rock density of 2.67g/cm3 was used. An exploration program would need to be completed, including twinning of historical drill holes, in order to verify the Dieter Lake historical estimate as a current Mineral Resource.*

*For Matoush, as disclosed in the above noted press release, the historical estimate was prepared by RPA using block U<sub>3</sub>O<sub>8</sub> grades within a wireframe model that were estimated by ordinary kriging. The historical estimate was estimated at a cut-off grade of 0.1% U<sub>3</sub>O<sub>8</sub> and using an average long-term uranium price of US$75 per pound. Six zones make up the historical estimate at Matoush: am-15, mt-34, mt-22, mt-02, mt-06, and mt-36. Each zone is made up of one or more lenses, most of which strike north (009°) and dip steeply (87°) to the east. Outlines of the mineralized lenses were interpreted on ten-metre spaced vertical sections. Minimum criteria of 0.10% U<sub>3</sub>O<sub>8</sub> over 1.5 metre true thickness was used as a guide. An exploration program would need to be conducted, including twinning of historical drill holes, in order to verify the Matoush historical estimate as a current Mineral Resource.*

ISOENERGY LTD.

For the three months ended March 31, 2026 and 2025

*For Ben Lomond, as disclosed in the above noted technical report, the historical estimate was prepared by the Australian Atomic Energy Commission (AAEC) using a sectional method. The parameters used in the selection of the ore intervals were a minimum true thickness of 0.5 metres and maximum included waste (true thickness) of 5 metres. Resource zones were outlined on 25 metre sections using groups of intersections, isolated intersections were not included. The grades from the composites were area weighted to give the average grade above a threshold of 500 ppm uranium. The area was measured on each 25 metre section to give the tonnage at a bulk density of 2.603. An exploration program would need to be conducted, including twinning of historical drill holes, in order to verify the Ben Lomond historical estimate as a current Mineral Resource.*

*For the Milo Project, as disclosed in the above noted scoping study, the historical estimate was prepared by Peter Owens and Basile Dean of Mining One Consultants. An exploration program would need to be conducted, including twinning of a selection of certain holes, along with updating of mining processing and certain cost estimates in order to verify the Milo Project historical resource estimate as a current Mineral Resource estimate.*

**ISOENERGY LTD.**

**NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

(Unaudited, expressed in Canadian Dollars)

**FOR THE THREE MONTHS ENDED MARCH 31, 2026 AND 2025**

**1.** **REPORTING ENTITY** 

IsoEnergy Ltd. ("**IsoEnergy**", or the "**Company**") is engaged in the acquisition, exploration and development of uranium properties in Canada, the United States of America and Australia. The Company's registered and records office is located at 217 Queen Street West, Unit 401, Toronto, Ontario M5V 0R2. The Company exists under the *Business Corporations Act (Ontario)*. The Company's common shares are listed on the Toronto Stock Exchange (the "**TSX**") under the symbol "ISO". The Company's common shares began trading on the New York Stock Exchange American LLC ("**NYSE-A**") on May 5, 2025 under the symbol "ISOU".

The Company primarily holds its mineral interests directly or indirectly through the following wholly owned subsidiaries:

&nbsp;&nbsp;&nbsp;&nbsp;· Consolidated Uranium Inc. ()"**Consolidated Uranium**") (Ontario, Canada)

&nbsp;&nbsp;&nbsp;&nbsp;· ICU Australia Pty Ltd. (Australia)

&nbsp;&nbsp;&nbsp;&nbsp;· Management X Pty Ltd. (Australia)

&nbsp;&nbsp;&nbsp;&nbsp;· CUR Australia Pty Ltd. (Australia)

&nbsp;&nbsp;&nbsp;&nbsp;· 12942534 Canada Ltd. (Canada)

&nbsp;&nbsp;&nbsp;&nbsp;· Virginia Uranium Inc. (Virginia, United States)

&nbsp;&nbsp;&nbsp;&nbsp;· CUR Sage Plain Uranium, LLC (Utah, United States)

&nbsp;&nbsp;&nbsp;&nbsp;· CUR Henry Mountains Uranium, LLC (Utah, United
States)

&nbsp;&nbsp;&nbsp;&nbsp;· White Canyon Uranium, LLC (Utah, United States)

&nbsp;&nbsp;&nbsp;&nbsp;· 2596190 Alberta Ltd. (Alberta, Canada)

As of March 31, 2026, NexGen Energy Ltd ("**NexGen**") holds 29.9% of IsoEnergy's outstanding common shares.

**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 March 31, 2026, the Company had accumulated losses of $105,174,420 and adjusted working capital of $183,253,876 (adjusted working capital is defined as current assets less current liabilities, excluding flow-though share premium liabilities and debenture liabilities). The Company depends on external financing for its operational expenses.

The business of exploring for and mining of minerals involves a high degree of risk. As an exploration company, IsoEnergy is subject to risks and challenges similar to companies at a comparable stage. These risks include, but are not limited to, negative operating cash flow and dependence on third party financing; the uncertainty of additional financing; the Company's limited operating history; the lack of known mineral reserves; the influence of a large shareholder; alternate sources of energy and uranium prices; aboriginal title and consultation issues; risks related to exploration activities generally; reliance upon key management and other personnel; title to properties; uninsurable risks; conflicts of interest; permits and licenses; environmental and other regulatory requirements; political regulatory risks; competition; and the volatility of share prices.

These Unaudited Condensed Consolidated Interim Financial Statements for the three months ended March 31, 2026 and 2025 (the "**Interim Financial Statements**") have been prepared using International Financial Reporting Standards ("**IFRS**") applicable to a going concern, which assumes that the Company will be able to realize its assets and discharge its liabilities in the normal course of business for the foreseeable future. The ability of the Company to continue as a going concern is dependent on its ability to obtain financing and achieve future profitable operations.

The underlying value of IsoEnergy's exploration and evaluation assets is dependent upon the existence and economic recovery of mineral resources or reserves and is subject to, but not limited to, the risks and challenges identified above.

**3.** **BASIS OF PRESENTATION** 

**Statement of Compliance**

The Interim Financial Statements have been prepared in accordance with International Accounting Standard ("**IAS**") 34, *Interim Financial Reporting*. They do not include all of the information required by IFRS for annual financial statements and should be read in conjunction with the audited consolidated annual financial statements as at and for the year ended December 31, 2025.

**ISOENERGY LTD.**

**NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

(Unaudited, expressed in Canadian Dollars)

**FOR THE THREE MONTHS ENDED MARCH 31, 2026 AND 2025**

**3.** **BASIS OF PRESENTATION (continued)** 

**Basis of Presentation**

The Interim Financial Statements have been prepared on a historical cost basis, except for certain financial instruments which have been measured at fair value. In addition, the Interim Financial Statements have been prepared using the accrual basis of accounting except for cash flow information. All monetary amounts expressed in the Interim Financial Statements are referenced as Canadian dollar amounts ("**$**"), unless otherwise noted. Monetary amounts expressed in US dollars and Australian dollars are referenced as ("**US$**") and ("**AUD$**"), respectively. The Interim Financial Statements are presented in Canadian dollars, which is the functional currency of the Company's Canadian subsidiaries. The functional currency for the Company's subsidiaries in the United States is US dollars. The functional currency for the Company's subsidiaries in Australia is Australian dollars.

The Interim Financial Statements of the Company consolidate the accounts of the Company and its subsidiaries. All intercompany transactions, balances, and unrealized gains and losses from intercompany transactions are eliminated on consolidation. The Company holds a 50% interest in an unincorporated joint venture with Purepoint Uranium Group Inc. ("**Purepoint Uranium**"), comprising of a portfolio of exploration and evaluation assets located in Saskatchewan, Canada (the "**Purepoint Joint Venture**"). The Purepoint Joint Venture is governed by a formal joint venture agreement (the "**Joint Venture Agreement**") and not through any other separate legal vehicle or entity. The Company accounts for the Purepoint Joint Venture as a joint operation and has proportionately consolidated its share of assets, liabilities, incomes and expenses.

Subsidiaries consist of entities over which the Company is exposed to, or has rights to, variable returns as well as the ability to affect those returns through the power to direct the relevant activities of the entity. Subsidiaries are fully consolidated from the date control is transferred to the Company and are de-consolidated from the date control ceases.

**4.** **CRITICAL ACCOUNTING JUDGMENTS, ESTIMATES AND ASSUMPTIONS** 

The preparation of the Interim Financial Statements requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, and contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. 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 in the circumstances. Uncertainty about these judgments, estimates and assumptions could result in outcomes that require a material adjustment to the carrying amount of the asset or liability affected in future periods.

Information about significant areas of judgement and estimation uncertainty considered by management in preparing the financial statements are set out in Note 4 to the consolidated annual financial statements for the year ended December 31, 2025 and have been consistently followed in preparation of the Interim Financial Statements.

**5.** **MATERIAL ACCOUNTING POLICIES** 

The accounting policies followed by the Company are set out in the consolidated annual financial statements for the year ended December 31, 2025 and have been consistently followed in the preparation of the Interim Financial Statements.

The following standard has been issued and is effective:

**Amendments to IFRS 9 and IFRS 7 – Classification and Measurement of Financial Instruments**

In May 2024, the International Accounting Standard Board ("**IASB**") issued *'Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7)*'. The amendments clarify the date of recognition and derecognition of some financial assets and financial liabilities, with a new exception that permits companies to elect to derecognize certain financial liabilities settled via electronic payment systems earlier than the settlement date. The amendments apply for annual reporting periods beginning on or after January 1, 2026, and are applied retrospectively. There were no changes to the Interim Financial Statements from adopting these amendments.

The following standard has been issued and is not yet effective:

**IFRS 18 – Presentation and Disclosure in Financial Statements**

The IASB has issued IFRS 18 – *Presentation and Disclosure in Financial Statements* ("**IFRS 18**"), which replaces IAS 1 – *Presentation of Financial Statements*. IFRS 18 introduces new requirements for the presentation of financial performance, including revised categories in the statements of loss, enhanced disclosures on management-defined performance measures, and greater consistency in financial statement presentation. The standard is effective for annual reporting periods beginning on or after January 1, 2027 and applies retrospectively, with early adoption permitted.

The Company has not early adopted IFRS 18 and continues to evaluate the impact of the forthcoming standard in preparing the Interim Financial Statements.

**FOR THE THREE MONTHS ENDED MARCH 31, 2026 AND 2025**

**6.** **TRANSACTIONS** 

&nbsp;&nbsp;&nbsp;&nbsp;**(a)** **Sale of Argentina assets** 

On July 19, 2024, the Company completed the sale of all of its shares in a previously wholly held subsidiary, which held all the Company's assets in Argentina which primarily included the Laguna Salada project and the Huemul project, to a third-party buyer, Jaguar Uranium Corp. ("**Jaguar Uranium**").

Consideration received from the sale primarily included:

&nbsp;&nbsp;&nbsp;&nbsp;· US$10.0 million of common shares of Jaguar Uranium,
being 2,000,000 shares at a price of US$5.00 per share. Should Jaguar Uranium complete a public listing or a concurrent financing at less
than the price of US$5.00 per share, the Company is entitled to additional common shares ()"**Top Up Shares**") of Jaguar
Uranium such that the total common shares held maintains a value of US$10.0 million, with the amount of Top Up Shares issued limited to
a minimum price of US$4.00 per share. Should Jaguar Uranium not complete a public listing or not complete a concurrent financing within
12 months of the closing date, the Company is entitled to additional common shares of Jaguar Uranium (the "**Additional Jaguar Uranium Shares** ").

&nbsp;&nbsp;&nbsp;&nbsp;· Net Smelter Returns ()"**NSR** ")
royalty of 2% on all production from the Laguna Salada project ()"**Laguna Salada NSR** "). Jaguar Uranium retains a buy-back
option for 1% of the Laguna Salada NSR, exercisable for 7 years at a price of US$2.5 million.

&nbsp;&nbsp;&nbsp;&nbsp;· NSR royalty of 1% on all production from the
Huemul project ()"**Huemul NSR** "). The Company retained a buy-back option on an existing royalty agreement on the Huemul
project ()"**Huemul Buy-back Option** ").

During the three months ended March 31, 2026, Jaguar Uranium completed a public listing and a concurrent financing at a price of US$4.00 per share. As a result, the Company was issued and received the Additional Jaguar Uranium Shares and the Top Up Shares, for total of 1,000,000 common shares of Jaguar Uranium received with a fair value of $4,498,560 (US$3,300,000), which was recorded as a gain on sale of assets.

&nbsp;&nbsp;&nbsp;&nbsp;**(b)** **Terminated transaction with Anfield Energy Inc.** 

On October 1, 2024, the Company and Anfield Energy Inc. ("**Anfield Energy**") entered into a definitive agreement (the "**Arrangement Agreement**"), pursuant to which IsoEnergy would acquire all of the issued and outstanding common shares of Anfield Energy by way of a court-approved plan of arrangement (the "**AEC Arrangement**"). In connection with the AEC Arrangement, IsoEnergy provided a bridge loan in the form of a promissory note of approximately $6.0 million to Anfield Energy, with an interest rate of 15% per annum and a maturity date of April 1, 2025 (the "**Bridge Loan**"). The Bridge Loan was issued for purposes of satisfying working capital and other obligations of Anfield Energy through to the closing of the proposed transaction. IsoEnergy also provided an indemnity for up to US$3.0 million in principal with respect to certain of Anfield Energy's property obligations (the "**Indemnity**").

The Arrangement Agreement provided that either party could unilaterally terminate the Arrangement Agreement if all conditions precedent had not been satisfied by December 31, 2024. Anfield Energy terminated the Arrangement Agreement on January 14, 2025. Anfield Energy repaid the full amount due under the Bridge Loan of $6,168,995, including accrued interest, on January 21, 2025. The Company received a full and final release from the Indemnity on March 3, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;**(c)** **Joint Venture Agreement: Put Option exercise** 

The Company initially held a 60% interest and Purepoint Uranium initially held a 40% interest in the Purepoint Joint Venture. The Joint Venture Agreement included an option to adjust the interests to 50% for each party through the exercise of mutually exclusive put and call options, such that the Company had an option to sell (the "**Put Option**") and Purepoint Uranium had an option to acquire (the "**Call Option**") 10% of IsoEnergy's initial interest in exchange for 4,000,000 common shares of Purepoint Uranium. The Company exercised its Put Option on January 14, 2025 and the interests in the Purepoint Joint Venture for both the Company and Purepoint Uranium were adjusted to 50%. After the exercise of the put option, the Company's carrying amount in the Purepoint Joint Venture was reduced by $1,060,000, based on the closing share price of Purepoint Uranium on the exercise date. Through the Joint Venture Agreement, the Company held a further option to purchase an additional 1% interest in the Purepoint Joint Venture from Purepoint Uranium in exchange for $2.0 million (the "**Additional Option**"). The Additional Option expired on February 28, 2026.

The ownership interests of each party are subject to standard dilution if either party fails to contribute to approved programs or expenditures of the Joint Venture Properties. If either party's interest is reduced to 10% or less, then that party will relinquish its entire interest in the Purepoint Joint Venture in exchange for a 2% NSR royalty on the Joint Venture Properties. The remaining party can purchase 1% of the NSR royalty for $2.0 million.

Purepoint Uranium acts as the operator of the Joint Venture Properties in the exploration phase. Once the Joint Venture Properties advance to the pre-development stage, the Company will assume the role of operator.

**FOR THE THREE MONTHS ENDED MARCH 31, 2026 AND 2025**

**6.** **TRANSACTIONS (continued)** 

&nbsp;&nbsp;&nbsp;&nbsp;**(f)** **Proposed acquisition of Toro Energy Limited** 

On October 12, 2025, the Company and Toro Energy Limited ("**Toro Energy**") entered into a scheme implementation deed (the "**SID**") pursuant to which IsoEnergy, through one of its wholly owned subsidiaries, will acquire all of the issued and outstanding ordinary shares of Toro Energy (the "**Toro Energy Shares**") by way of a scheme of arrangement under Australia's *Corporations Act 2001 (Cth)* (the "**Toro Scheme**"). Toro Energy is an Australian Securities Exchange ("**ASX**") listed company that owns 100% of the Wiluna uranium project in Western Australia, Australia, as well as other exploration stage uranium properties in Australia.

Under the terms of the SID, shareholders of Toro Energy (the "**Toro Energy Shareholders**") will receive 0.036 of a common share of IsoEnergy for each Toro Energy Share. Completion of the Toro Scheme is subject to various conditions, including but not limited to: approval of Toro Energy Shareholders; court approval; applicable regulatory approvals, including approval of the ASX, TSX, and NYSE American; and an independent expert concluding and continuing to conclude that the Toro Scheme is in the best interests of Toro Energy Shareholders.

The SID includes customary representations and warranties for a transaction of this nature, as well as notification obligations and a matching right regime in the event any superior proposal is received by Toro Energy. The SID also provides for customary deal-protection measures, including a break fee of approximately AUD$700,000, payable by either IsoEnergy or Toro Energy in certain circumstances.

Following the completion of the Toro Scheme, the IsoEnergy Shares will continue to trade on the TSX and NYSE-A and the Toro Energy Shares will be delisted from the ASX. The Company retained an investment bank to advise on the Toro Scheme and provide a fairness opinion to the Company's Board of Directors, for which the investment bank is entitled to a fixed fee customary for this type of transaction, no part of which is contingent upon the opinion being favourable or upon completion the Toro Scheme or any alternative transaction. The Company has also agreed to pay an additional fee for the investment bank's advisory services in connection with the Toro Scheme, which is contingent on its successful completion.

Toro Energy Shareholders will be asked to approve the Toro Scheme at a shareholder meeting (the "**Toro Energy Shareholders Meeting**"). The Toro Scheme is expected to close after the Toro Energy Shareholders Meeting, which is expected to take place in the first half of 2026. Costs incurred as of March 31, 2026 in respect of the Toro Scheme of $828,735 are included in prepaid expenses.

**11.** **CONVERTIBLE DEBENTURES** 

**2020 Debentures**

On August 18, 2020, IsoEnergy entered into an agreement with Queen's Road Capital Investment Ltd. ("**QRC**") for a US$6 million private placement of unsecured convertible debentures (the "**2020 Debentures**"). The 2020 Debentures carried a coupon ("**Interest**") of 8.5% per annum, of which 6% was payable in cash and 2.5% payable in common shares of the Company, over a 5-year term. The principal amount of the 2020 Debentures (converted into Canadian dollars) was convertible into common shares of the Company at QRC's option at a conversion price (the "**Conversion Price**") of $3.52 per share, up to a maximum (the "**Maximum Conversion Shares**") of 2,301,577 common shares. The Company received gross proceeds of $7,902,000 (US$6,000,000) on issuance of the 2020 Debentures.

On January 19, 2025, QRC elected to convert US$3,000,000 of the principal of the 2020 Debentures for 1,221,818 common shares of the Company (Note 14). Fair value of $13,928,728 of the principal converted was derecognized, which was determined based on the closing share price of the Company on the date of conversion. Interest of $27,539 owed on the US$3,000,000 principal from January 1, 2025 to the date of the conversion was settled in cash.

On August 1, 2025, QRC elected to convert the remaining principal amount of the 2020 Debentures of US$3,000,000 for 1,195,250 common shares of the Company (Note 14). Fair value of $10,194,879 of the remaining principal converted was derecognized, which was determined based on the closing share price of the Company on the date of conversion. Interest of $30,357 owed on the US$3,000,000 remaining principal from July 1, 2025 to the date of conversion was settled in cash. A loss of $167,938 was recorded on the settlement of the remaining principal amount of the 2020 Debentures, being the difference between the remaining fair value derecognized and the fair value of the common shares issued, including the Maximum Conversion Shares and the common shares issued to settle the Exchange Rate Fee (as defined below).

In the three months ended March 31, 2025, the Company incurred interest expense of $119,032 on the 2020 Debentures.

**2022 Debentures**

On December 6, 2022, IsoEnergy entered into an agreement with QRC for a US$4 million private placement of unsecured convertible debentures (the "**2022 Debentures**" and together with the 2020 Debentures, the "**Debentures**"). The 2022 Debentures carry Interest at 10% per annum, of which 7.5% is payable in cash and 2.5% payable in common shares of the Company, over a 5-year term. The principal amount of the 2022 Debentures (converted into Canadian dollars) is convertible into common shares of the Company at the holder's option at a Conversion Price of $17.32 per share, up to 366,070 Maximum Conversion Shares. The Company received gross proceeds of $5,459,600 (US$4,000,000) on issuance of the 2022 Debentures.

In the three months ended March 31, 2026, the Company incurred interest expense of $137,187 (2025: $143,518) on the 2022 Debentures.

The Company is entitled, at any time the 20-day VWAP of the Company's shares listed on the TSX exceeds 130% of the applicable Conversion Price, to redeem the 2022 Debentures at par plus accrued and unpaid Interest.

Upon completion of a change of control (which also requires in the case of the holders' right to redeem the 2022 Debentures, a change in the Chief Executive Officer of the Company), the holders of the 2022 Debentures or the Company may require the Company to purchase or the holders to redeem, as the case may be, any outstanding 2022 Debentures in cash at 115% of the principal amount, plus accrued but unpaid interest, if any. In addition, upon the public announcement of a change of control that is supported by the Board of Directors, the Company may require the holders of the 2022 Debentures to convert the 2022 Debentures into common shares at the Conversion Price provided the consideration payable upon the change of control exceeds the Conversion Price and is payable in cash.

**General terms of the Debentures**

Interest is payable semi-annually on June 30 and December 31, and common shares of the Company issued as partial payment of Interest are, subject to TSX approval, issuable at a price equal to the 20-day volume-weighted average trading price ("**VWAP**") of the Company's common shares on the TSX on the twenty days prior to the date such Interest is due.

On the conversion of any portion of the principal amount of the Debentures, if the number of common shares to be issued on such conversion, taking into account all common shares issued in respect of all prior conversions of such Debentures, would result in the common shares to be issued exceeding the Maximum Conversion Shares for such Debentures, on conversion QRC shall be entitled to receive a payment (an "**Exchange Rate Fee**") equal to the number of common shares that are not issued as a result of exceeding the Maximum Conversion Shares, multiplied by the 20-day VWAP. IsoEnergy can elect to pay any such Exchange Rate Fee in cash or, subject to the TSX approval, in common shares of the Company.

**FOR THE THREE MONTHS ENDED MARCH 31, 2026 AND 2025**

**12.** **COMMITMENTS (continued)** 

**Flow-through funding commitments**

The Company has raised funds through the issuance of flow-through shares. Based on Canadian tax law, the Company is required to spend this amount on eligible exploration expenditures by December 31 of the year following the year in which the shares were issued.

The premium received for a flow-through share, which is the price received for the share in excess of the market price of the share, is recorded as a flow-through share premium liability. This liability is subsequently reduced when the required exploration expenditures are made, on a pro rata basis, and accordingly, a recovery of flow-through premium is then recorded as a reduction in the deferred tax expense to the extent that deferred income tax assets are available.

**16.** **FINANCIAL INSTRUMENTS** 

The Company's financial instruments consist of cash and cash equivalents, accounts receivable, marketable securities, accounts payable and accrued liabilities, and convertible debentures.

**Fair Value Measurement**

The Company classifies the fair value of financial instruments according to the following hierarchy based on the amount of observable inputs used to value the instrument:

&nbsp;&nbsp;&nbsp;&nbsp;· Level 1 – quoted prices in active markets
for identical assets or liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;· Level 2 – inputs other than quoted prices
included in Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from
prices).

&nbsp;&nbsp;&nbsp;&nbsp;· Level 3 – inputs for the asset or liability
that are not based on observable market data.

The fair values of the Company's cash and cash equivalents, accounts receivable, and accounts payable and accrued liabilities approximate their carrying value, due to their short-term maturities or liquidity.

(Unaudited, expressed in Canadian Dollars)

**FOR THE THREE MONTHS ENDED MARCH 31, 2026 AND 2025**

**16.** **FINANCIAL INSTRUMENTS (continued)** 

**Fair Value Measurement (continued)**

The 2022 Debentures are re-measured at fair value at each reporting date with any change in fair value recognized in profit or loss, except for the change in fair value that is attributable to change in credit risk, which is presented in other comprehensive income (loss) (Note 11). The 2022 Debentures are classified as Level 2.

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 7). The common shares included in marketable securities are Level 1, except for the common shares of privately held marketable securities, which are Level 3 and their fair value is primarily based on the price of their most recent share issuances. The warrants included in marketable securities are Level 2.

During the three months ended March 31, 2026, Jaguar Uranium and Verdera Energy Corp. completed public listings. As a result, the Company transferred its common shares held in these entities from Level 3 to Level 1 (Note 7). The fair value transferred is measured at the share price at the time of the public listing of each entity.

**Financial instrument risk exposure**

As at March 31, 2026, the Company's financial instrument risk exposure and the impact thereof on the Company's financial instruments are summarized below:

&nbsp;&nbsp;&nbsp;&nbsp;**(a)** **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. As at March 31, 2026, the Company has cash and cash equivalents on deposit with large banks in Canada, the United States, and Australia. Credit risk is concentrated as a significant amount of the Company's cash and cash equivalents is held at a Canadian financial institution. Management believes the risk of loss to be remote.

The Company's accounts receivable mostly consists of input tax credits receivable from the Governments of Canada and Australia and amounts receivable from related parties. Accordingly, the Company does not believe it is subject to significant credit risk.

&nbsp;&nbsp;&nbsp;&nbsp;**(b)** **Liquidity Risk** 

Liquidity risk is the risk that an entity will encounter difficulty in raising funds to meet its obligations under financial instruments. The Company manages liquidity risk by maintaining sufficient cash balances that are accessible on deposit or on short-term notice. Liquidity requirements are managed based on expected cash flows to ensure that there is sufficient capital to meet short-term obligations. As at March 31, 2026, the Company had an adjusted working capital balance of $183,253,876 (adjusted working capital is defined as current assets less current liabilities, excluding flow-though share premium liabilities and debenture liabilities), including cash and cash equivalents of $130,537,804.

&nbsp;&nbsp;&nbsp;&nbsp;**(c)** **Market Risk** 

Market risk is the risk of loss that may arise from changes in market factors such as interest rates, foreign exchange rates and commodity and equity prices.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(i)** **Interest Rate Risk** 

Interest rate risk is the risk that the future cash flows from a financial instrument will fluctuate due to changes in market interest rates. The Company holds its cash and cash equivalents 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 and cash equivalent balances as of March 31, 2026. The interest on the 2022 Debentures is fixed and not subject to market fluctuations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(ii)** **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 of movements in individual equity prices or general movements in the level of the stock market on the Company's financial performance. Commodity price risk is defined as the potential adverse impact of commodity price movements and volatilities on financial performance and economic value. Future declines in commodity prices may impact the valuation of long-lived assets. The Company closely monitors the commodity prices of uranium, individual equity movements, and the stock market. The Company holds marketable securities which are subject to equity price risk.

(Unaudited, expressed in Canadian Dollars)

**FOR THE THREE MONTHS ENDED MARCH 31, 2026 AND 2025**

**16.** **FINANCIAL INSTRUMENTS (continued)** 

**Financial instrument risk exposure (continued)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(iii)** **Foreign Currency Risk** 

The Company enters into transactions denominated in foreign currencies from time-to-time and in addition to Canada, the Company operates in the United States and Australia, and is therefore exposed to foreign exchange risk arising from transactions denominated in foreign currencies. Foreign exchange risk arises when future commercial transactions or recognized assets or liabilities are denominated in a currency that is not the Company's functional currency. Consequently, fluctuations of the Canadian dollar in relation to other currencies impact the fair value of financial assets, liabilities and operating results. Financial instruments subject to foreign currency risk include US dollar and Australian dollar denominated cash, US dollar and Australian dollar accounts receivable, US dollar and Australian dollar marketable securities, US dollar and Australian dollar accounts payable and accrued liabilities, and the 2022 Debentures. The Company maintains Canadian, US and Australian dollar bank accounts.

The Company is exposed to foreign exchange risk on its US dollar denominated cash, accounts payable and accrued liabilities, accounts receivable, marketable securities and 2022 Debentures. At its maturity date, the principal amount of the 2022 Debentures is due in full, and prior to then at a premium upon the occurrence of certain events, including a change of control. The Company holds sufficient US dollars to make all cash interest payments due under the 2022 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 2022 Debentures more costly to repay.

A 5% change in the Canadian/US dollar exchange rate can result in a net increase or decrease in the Company's US dollar denominated financial instruments of $675,540 that would flow through the consolidated statement of income and comprehensive (loss) income.

The Company is exposed to foreign exchange risk on its Australian dollar denominated cash, accounts receivable, marketable securities, and accounts payable and accrued liabilities. Accordingly, the Company is subject to risks associated with fluctuations in the Canadian/Australian dollar exchange rate that may impact on its operating results.

A 5% change in the Canadian/Australian dollar exchange rate can result in a net increase or decrease in the Company's Australian dollar denominated financial instruments by $241,327 that would flow through consolidated statement of income and comprehensive (loss) income.

**17.** **SEGMENT INFORMATION** 

The Company has identified its operating segments based on the internal reports that are reviewed and used by the chief executive officer and the executive management in assessing performance and in determining the allocation of resources. The Company has one operating segment, being the acquisition, exploration and development of uranium properties.

Geographically, the Company's non-current assets are identified by country, being Canada, the United States, and Australia, with the corporate office in Canada. Geographic disclosure is as follows.
