Notes to condensed consolidated interim financial statements

(Unaudited)

(Cdn$ thousands, except per share amounts and as noted)

1.	Cameco Corporation

Cameco Corporation is incorporated under the Canada Business Corporations Act. The address of its registered office is 2121 11th Street West, Saskatoon, Saskatchewan, S7M 1J3. The condensed consolidated interim financial statements as at and for the period ended September 30, 2026 comprise Cameco Corporation and its subsidiaries (collectively, the Company or Cameco) and the Company’s interests in associates and joint arrangements.

Cameco is one of the world’s largest providers of the uranium needed to generate clean, reliable baseload electricity around the globe. The Company has operations in northern Saskatchewan and the United States, as well as a 40% interest in Joint Venture Inkai LLP (JV Inkai), a joint arrangement with Joint Stock Company National Atomic Company Kazatomprom (Kazatomprom), located in Kazakhstan. Cameco also has a 49% interest in Westinghouse Electric Company (Westinghouse), a joint venture with Brookfield Renewable Partners and its institutional partners (collectively, Brookfield). Westinghouse is one of the world’s largest nuclear services businesses with corporate headquarters in Pennsylvania and operations around the world. Both JV Inkai and Westinghouse are accounted for on an equity basis (see note 7).

Cameco has two operating mines, Cigar Lake and McArthur River as well as a mill at Key Lake. The Rabbit Lake operation was placed in care and maintenance in 2016. Cameco’s operations in the United States, Crow Butte and Smith Ranch-Highland, are not currently producing as the decision was made in 2016 to curtail production and defer all wellfield development. See note 20 for the financial statement impact.

The Company is also a leading provider of nuclear fuel processing services, supplying much of the world’s reactor fleet with the fuel to generate one of the cleanest sources of electricity available today. It operates the world’s largest commercial refinery in Blind River, Ontario, controls a significant portion of the world UF₆ primary conversion capacity in Port Hope, Ontario and is a leading manufacturer of fuel assemblies and reactor components for CANDU reactors at facilities in Port Hope and Cobourg, Ontario.

2.	Material accounting policies

A.	Statement of compliance

These condensed consolidated interim financial statements have been prepared in accordance with IAS 34 Interim Financial Reporting. The condensed consolidated interim financial statements do not include all of the information required for full annual financial statements and should be read in conjunction with Cameco’s annual consolidated financial statements as at and for the year ended December 31, 2025.

These condensed consolidated interim financial statements were authorized for issuance by the Company’s board of directors on October 29, 2026.

B.	Basis of presentation

These condensed consolidated interim financial statements are presented in Canadian dollars, which is the Company’s functional currency. All financial information is presented in Canadian dollars, unless otherwise noted. Amounts presented in tabular format have been rounded to the nearest thousand except per share amounts and where otherwise noted.

The condensed consolidated interim financial statements have been prepared on the historical cost basis except for the following material items which are measured on an alternative basis at each reporting date:


Derivative financial instruments		Fair value through profit or loss (FVTPL)

Equity investments		Fair value through other comprehensive income (FVOCI)

Liabilities for cash-settled share-based payment arrangements		FVTPL

Net defined benefit liability		Fair value of plan assets less the present value of the defined benefit obligation

The preparation of the condensed consolidated interim financial statements in conformity with International Financial Reporting Standards (IFRS), as issued by the International Accounting Standards Board (IASB), requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenue and expenses. Actual results may vary from these estimates.

In preparing these condensed consolidated interim financial statements, the significant judgments made by management in applying the Company’s accounting policies and key sources of estimation uncertainty were the same as those that applied to the consolidated financial statements as at and for the year ended December 31, 2025.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in note 5 of the December 31, 2025, consolidated financial statements. In addition, significant estimates are required for the determination of fair value assets and liabilities acquired in a business combination. Further information about the techniques and assumptions used to measure acquisition fair values is included in note 4.

3.	Accounting standards

A.	Changes in accounting policy

A number of amendments to existing standards became effective on January 1, 2026, but other than the one noted below, they were not applicable to the Company’s financial statements.

i.	Classification and measurement of financial instruments

In May 2024, the International Accounting Standards Board (IASB) issued Amendments to the Classification and Measurement of Financial Instruments, amending IFRS 9 Financial Instruments and IFRS 7 Financial Instruments: Disclosures. The amendments clarified the recognition and derecognition dates of certain financial assets and liabilities, and amended the requirements related to settling financial liabilities using an electronic payment system. It also clarified the assessment of certain cash flow characteristics and additional disclosure requirements for financial instruments with contingent features and equity instruments designated at fair value through other comprehensive income. The amendments did not have a material impact on the Company’s financial statements and no additional disclosures were required.

B.	New standards and interpretations not yet adopted

A number of new standards and amendments to existing standards are not yet effective for the period ended September 30, 2026, and have not been applied in preparing these condensed consolidated interim financial statements. Cameco does not intend to early adopt any of the standards and amendments and does not expect them to have a material impact on its financial statements. The one new standard that is expected to have an impact on the financial statement presentation and disclosures is described below.

i.	Presentation and disclosure in financial statements

In April 2024, the IASB issued IFRS 18, Presentation and Disclosure in Financial Statements (IFRS 18), replacing IAS 1, Presentation of Financial Statements. IFRS 18 is effective for periods beginning on or after January 1, 2027. Retrospective application is required, with early adoption permitted. IFRS 18 is expected to improve the quality of financial reporting by requiring the classification of income and expenses in the statement of profit or loss into five categories and the presentation of

two newly defined subtotals, requiring disclosures about management-defined performance measures, and introducing enhanced principles for aggregation and disaggregation of information. Cameco continues to assess the impact of this standard on its financial statements and disclosures.

4.	Acquisition of additional interest in Cigar Lake Joint Venture (CLJV)

On July 2, 2026, Cameco and Orano Canada Inc. (Orano) completed the acquisition of TEPCO Resources Inc.’s (TEPCO) 5.000% participating interest in the CLJV by acquiring their pro rata shares through an asset purchase. Cameco’s ownership stake in the Cigar Lake uranium mine in northern Saskatchewan is now 57.418% (previously 54.547%). The primary reason for the business combination was to increase our ownership interest.

Cash consideration of $113,197,000 was paid for the additional 2.871% interest. The additional interest has been proportionately consolidated with the results of Cameco commencing on July 2, 2026.

CLJV allocates uranium production to each joint operation participant and the joint operation participant derives revenue directly from the sale of such product. Mining and milling expenses incurred by joint operations are included in the cost of inventory. As such, there is no revenue or profit or loss of the acquiree included in the consolidated statements of earnings. If the acquisition had occurred at the beginning of the year, Cameco’s share of production would have included an additional 225,000 pounds. The impact to the financial statements would not have been material.

Acquisition costs of $1,025,000 have been included in administration expense in the consolidated statements of earnings for the nine-month period ended September 30, 2026.

Included in the identifiable assets and liabilities acquired at the date of acquisition are inputs, production processes and outputs. Therefore, Cameco has determined that together the acquired set is a business. In accordance with the acquisition method of accounting, the purchase price was allocated to the underlying assets and liabilities assumed based on their fair values at the date of acquisition. Fair values were determined based on discounted cash flows and quoted market prices. The values assigned to the net assets acquired were as follows:


Property, plant and equipment	$	165,136
Working capital		157
Reclamation provision		(1,664	)
Sales contracts		(15,275	)
Deferred tax liability		(9,457	)

Net assets acquired	$	138,897

Cash paid		113,197

Bargain purchase gain^(a)	$	25,700

(a)

The bargain purchase gain resulted from applying the measurement requirements under IFRS 3, Business Combinations. This standard requires the measurement of assets and liabilities that were acquired as part of the transaction to be measured at fair value at the acquisition date. The acquisition date fair values exceeded the amount paid due primarily to the impact of rising uranium price forecasts. The resulting gain is included in other income in the consolidated statement of earnings.

The accounting for the acquisition will be revised if, within one year of the acquisition date, new information is obtained about facts and circumstances that existed at the date of acquisition. Revision will occur if this new information identifies adjustments to the above amounts, or any additional provisions that existed at the date of acquisition.

(a)

Cameco is required to remit or otherwise secure 50% of the cash taxes and transfer pricing penalties, plus related interest and instalment penalties assessed, in relation to its dispute with Canada Revenue Agency (CRA). In light of our view of the likely outcome of the case, Cameco expects to recover the amounts remitted to CRA, including cash taxes, interest and penalties paid.

(b)	As a result of Cameco’s dispute with CRA, Cameco has drawn down the tax pools available to us and we were required to remit cash tax for the 2024 to 2026 tax years. Cameco expects to recover this amount.

(c)

Cameco loaned 5,400,000 pounds of uranium concentrate to its joint venture partner, Orano Canada Inc., (Orano). Orano is obligated to repay the Company in kind with uranium concentrate no later than December 31, 2028. As at September 30, 2026, 3,000,000 pounds have been returned as repayment on this loan (December 31, 2025 - 3,000,000 pounds).

Cameco also loaned Orano 1,148,200 kgU of conversion supply and an additional 1,200,000 pounds of uranium concentrate. Repayment to Cameco is to be made in kind with U₃O₈ quantities drawn being repaid by December 31, 2027 and quantities of UF₆ conversion supply drawn by December 31, 2035.

As at September 30, 2026, 3,600,000 pounds of U₃O₈ (December 31, 2025 - 3,600,000 pounds) and 1,148,200 kgU of UF₆ conversion supply (December 31, 2025 - 1,148,200 kgU) were drawn on the loans. The values of the loans are recorded at Cameco’s weighted average cost of inventory at the time the loans were drawn.

A.	Joint ventures

i.	Westinghouse

Westinghouse is a nuclear reactor technology original equipment manufacturer and a global provider of products and services to commercial utilities and government agencies. Cameco holds a 49% interest and Brookfield holds 51%. Cameco has joint control with Brookfield over the strategic operating, investing and financing activities of Westinghouse. The Company determined that the joint arrangement should be classified as a joint venture after concluding that neither the legal form of the separate entity, the terms of the contractual arrangement, or other facts and circumstances would give the Company rights to the assets and obligations for the liabilities relating to the arrangement. As a result, Cameco accounts for Westinghouse on an equity basis.

Westinghouse provides outage and maintenance services, engineering support, instrumentation and controls equipment, plant modification, and components and parts to nuclear reactors. Westinghouse has three fabrication facilities that design and manufacture nuclear fuel supplies for light water reactors. In addition, Westinghouse designs, develops and procures equipment for the build of new nuclear reactor plants.

ii.

Global Laser Enrichment LLC (GLE)

GLE is the exclusive licensee of the proprietary Separation of Isotopes by Laser Excitation (SILEX) laser enrichment technology, a third-generation uranium enrichment technology. Cameco owns a 49% interest in GLE with an option to attain a majority interest of up to 75% ownership. Cameco has joint control with Silex Systems Limited over the strategic operating, investing and financing activities and as a result, accounts for GLE on an equity basis. In 2014, an impairment charge was recognized for its full carrying value of $183,615,000. Following the impairment, under the equity method of accounting, Cameco discontinued recognizing its share of losses in GLE. Cameco’s contributions to GLE are recorded in earnings as research and development.

B.	Associate

i.	JV Inkai

JV Inkai is the operator of the Inkai uranium deposit located in Kazakhstan. Cameco holds a 40% interest and Kazatomprom holds a 60% interest in JV Inkai. Cameco does not have joint control over the joint venture and as a result, Cameco accounts for JV Inkai on an equity basis.

JV Inkai is a uranium mining and milling operation that utilizes in-situ recovery (ISR) technology to extract uranium. The participants in JV Inkai purchase uranium from Inkai and, in turn, derive revenue directly from the sale of such product to third-party customers.

The following tables summarize the total comprehensive income of JV Inkai (100%):

(a)

Cameco has standby product loan facilities with various counterparties. The arrangements allow us to borrow up to 2,707,000 kgU of UF₆ conversion services and 7,920,000 pounds of U₃O₈ until January 1, 2032 with repayment in kind up to March 31, 2032. Under the facilities, standby fees of up to 2.1% are payable based on the market value of the facilities and interest is payable on the market value of any amounts drawn at rates ranging from 0.5% to 2.2%. The loans are recorded at the best estimate of the cost to settle the liability using Cameco’s weighted average cost of inventory. Certain facilities permit the lender to demand repayment with 90 days’ notice and accordingly the balances subject to these demand repayment terms are classified as current.

During the nine months ended September 30, 2026, Cameco repaid 51,000 kgU of UF₆ conversion services. At September 30, 2026, we have 1,234,000 kgU of UF₆ conversion services (December 31, 2025 - 1,285,000 kgU) drawn on the loans with contractual repayment in the following years:

kgU of UF₆		139,000		750,000		—		—		—		345,000		1,234,000

While 750,000 kgU have contractual repayment dates in 2027 and 345,000 kgU have contractual repayment dates beyond 2030, these amounts are subject to demand repayment provisions.

During the nine months ended September 30, 2026, Cameco borrowed an additional 750,000 pounds of U₃O₈ and repaid 132,000 pounds of U₃O₈. At September 30, 2026 we have 3,975,000 pounds of U₃O₈ (December 31, 2025 - 3,357,000 pounds) drawn with contractual repayment in the following years:


	2026		2027		2028		2029		2030		Thereafter		Total

Share capital

At September 30, 2026, there were 435,532,978 common shares outstanding. Options in respect of 39,063 shares are outstanding under the stock option plan and are exercisable up to 2027. For the quarter ended September 30, 2026, there were no options that were exercised resulting in the issuance of shares (2025 - 19,710). For the nine months ended September 30, 2026, there were 75,000 options exercised that resulted in the issuance of shares (2025 - 95,075).

12.

Revenue

Cameco’s uranium and fuel services sales contracts with customers contain both fixed and market-related pricing. Fixed-price contracts are typically based on a term-price indicator at the time the contract is accepted and escalated over the term of the contract. Market-related contracts are based on either the spot price or long-term price, and the price is quoted at the time of delivery rather than at the time the contract is accepted. These contracts often include a floor and/or ceiling prices, which are usually escalated over the term of the contract. Escalation is generally based on a consumer price index. The Company’s contracts contain either one of these pricing mechanisms or a combination of the two. There is no variable consideration in the contracts and therefore no revenue is considered constrained at the time of delivery. Cameco expenses the incremental costs of obtaining a contract as incurred as the amortization period is less than a year.

The following tables summarize Cameco’s sales disaggregated by geographical region and contract type and includes a reconciliation to Cameco’s reportable segments (note 20):

Cameco has recorded $595,934,000 of deferred tax assets (December 31, 2025 - $666,457,000). The realization of these deferred tax assets is dependent upon the generation of future taxable income in certain jurisdictions during the periods in which the Company’s deferred tax assets are available. The Company considers whether it is probable that all or a portion of the deferred tax assets will not be realized. In making this assessment, management considers all available evidence, including recent financial operations, projected future taxable income and tax planning strategies. Based on projections of future taxable income over the periods in which the deferred tax assets are available, realization of these deferred tax assets is probable and consequently the deferred tax assets have been recorded.

Reassessments

On February 18, 2021, the Supreme Court of Canada (Supreme Court) dismissed Canada Revenue Agency’s (CRA) application for leave to appeal the June 26, 2020 decision of the Federal Court of Appeal (Court of Appeal). The dismissal means that the dispute for the 2003, 2005 and 2006 tax years is fully and finally resolved in the Company’s favour.

In September 2018, the Tax Court of Canada (Tax Court) ruled that the marketing and trading structure involving foreign subsidiaries, as well as the related transfer pricing methodology used for certain intercompany uranium sales and purchasing agreements, were in full compliance with Canadian law for the tax years in question. Management believes the principles in the decision apply to all subsequent tax years, and that the ultimate resolution of those years will not be material to Cameco’s financial position, results of operations or liquidity in the year(s) of resolution.

As CRA continues to pursue reassessments for tax years subsequent to 2006, Cameco is utilizing its appeal rights under Canadian federal and provincial tax rules.

Cameco has pledged $245,947,000 of cash as security against certain of its letter of credit facilities. This cash is being used as collateral for an interest rate reduction on the letter of credit facilities. The collateral account has a term of five years effective November 1, 2023. Cameco retains full access to this cash and, accordingly, it is included in cash and cash equivalents.

B.	Fair value hierarchy

The fair value of an asset or liability is generally estimated as the amount that would be received on sale of an asset, or paid to transfer a liability in an orderly transaction between market participants at the reporting date. Fair values of assets and liabilities traded in an active market are determined by reference to last quoted prices, in the principal market for the asset or liability. In the absence of an active market for an asset or liability, fair values are determined based on market quotes for assets or liabilities with similar characteristics and risk profiles, or through other valuation techniques. Fair values determined using valuation techniques require the use of inputs, which are obtained from external, readily observable market data when available. In some circumstances, inputs that are not based on observable data must be used. In these cases, the estimated fair values may be adjusted in order to account for valuation uncertainty, or to reflect the assumptions that market participants would use in pricing the asset or liability.

All fair value measurements are categorized into one of three hierarchy levels, described below, for disclosure purposes. Each level is based on the transparency of the inputs used to measure the fair values of assets and liabilities:

Level 1 – Values based on unadjusted quoted prices in active markets that are accessible at the reporting date for identical assets or liabilities.

Level 2 – Values based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the asset or liability.

Level 3 – Values based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement.

When the inputs used to measure fair value fall within more than one level of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement in its entirety.

The following tables summarize the carrying amounts and level 2 fair value measurements of Cameco’s financial instruments:

As at September 30, 2026


	Carrying value			Fair Value
Derivative liabilities [note 9]
Foreign currency contracts		(100,486	)		(100,486	)
Interest rate contracts		(1,647	)		(1,647	)
Long-term debt [note 8]		(996,952	)		(1,022,360	)

Net	$	(1,099,085	)	$	(1,124,493	)

As at December 31, 2025


	Carrying value			Fair Value
Derivative assets [note 6]
Foreign currency contracts	$	21,166		$	21,166
Derivative liabilities [note 9]
Foreign currency contracts		(17,244	)		(17,244	)
Interest rate contracts		(1,677	)		(1,677	)
Long-term debt [note 8]		(996,348	)		(1,046,819	)

Net	$	(994,103	)	$	(1,044,574	)

The preceding tables exclude fair value information for financial instruments whose carrying amounts are a reasonable approximation of fair value. The carrying value of Cameco’s cash and cash equivalents, short-term investments, accounts receivable, and accounts payable and accrued liabilities approximates its fair value as a result of the short-term nature of the instruments.

There were no transfers between level 1 and level 2 during the period. Cameco does not have any financial instruments that are classified as level 1 or level 3 as of the reporting date.

C.	Financial instruments measured at fair value

Cameco measures its derivative financial instruments at fair value which is classified as recurring level 2 fair value measurement.

Cameco’s long-term debt is carried at amortized cost. The fair value is measured for disclosure purposes and determined using quoted market yields as of the reporting date, which ranged from 2.7% to 4.1% (2025—2.5% to 3.7%). Long-term debt is classified as a recurring level 2 fair value measurement.

Foreign currency derivatives consist of foreign currency forward contracts, options and swaps. The fair value of foreign currency options is measured based on the Black Scholes option-pricing model. The fair value of foreign currency forward contracts and swaps is measured using a market approach, based on the difference between contracted foreign exchange rates and quoted forward exchange rates as of the reporting date.

Interest rate derivatives consist of interest rate swap contracts. The fair value of interest rate swaps is determined by discounting expected future cash flows from the contracts. The future cash flows are determined by measuring the difference between fixed interest payments to be received and floating interest payments to be made to the counterparty based on Canada Overnight Repo Rate Average forward interest rate curves.

Where applicable, the fair value of the derivatives reflects the credit risk of the instrument and includes adjustments to take into account the credit risk of the Company and counterparty. These adjustments are based on credit ratings and yield curves observed in active markets at the reporting date.

D.	Derivatives

The following table summarizes the fair value of derivatives and classification on the consolidated statements of financial position:


	Sep 30/26			Dec 31/25
Non-hedge derivatives:
Foreign currency contracts	$	(100,486	)	$	3,922

Segmented information

Cameco has three reportable segments: uranium, fuel services and Westinghouse. Cameco’s reportable segments are strategic business units with different products, processes and marketing strategies. The uranium segment involves the exploration for, mining, milling, purchase and sale of uranium concentrate. The uranium segment also includes our share of earnings from our equity-accounted investee, JV Inkai (see note 7). The fuel services segment involves the refining, conversion and fabrication of uranium concentrate and the purchase and sale of conversion services. The Westinghouse segment reflects our earnings from this equity-accounted investment (see note 7). Westinghouse is a nuclear reactor technology original equipment manufacturer and a global provider of products and services to commercial utilities and government agencies. It provides outage and maintenance services, engineering support, instrumentation and controls equipment, plant modification, and components and parts to nuclear reactors.

Cost of sales in the uranium segment includes care and maintenance costs for our operations that have had production suspensions, including annual maintenance and other temporary shutdowns. Cameco expensed $33,120,000 of care and maintenance costs during the third quarter of 2026 (2025 - $35,094,000). For the nine months ended September 30, 2026, Cameco expensed $95,980,000 (2025 - $76,572,000).

Accounting policies used in each segment are consistent with the policies outlined in the summary of material accounting policies.

Business segments

Consistent with the presentation of financial information for internal management purposes, Cameco’s share of Westinghouse’s financial results has been presented as a separate segment. In accordance with IFRS, this investment is accounted for by the equity method of accounting in these consolidated financial statements and the associated revenue and expenses are eliminated in the “Adjustments” column.
