Cameco announces 2023 results; strategically positioned to increase tier-one production as security of supply contracting cycle advances; maintaining disciplined financial management and growth; improving Westinghouse outlook

Saskatoon, Saskatchewan, Canada, February 8, 2024 .. . . . . . . . . . . . . . . .

Cameco (TSX: CCO; NYSE: CCJ) today reported its consolidated financial and operating results for the fourth quarter and year ended December 31, 2023, in accordance with International Financial Reporting Standards (IFRS).

“Our 2023 financial performance benefitted from higher sales volumes and realized prices in our uranium and fuel services segments. Our net earnings, adjusted net earnings, and cash from operations all more than doubled compared to 2022, with adjusted EBITDA up 93%. In 2024, we expect strong financial performance as we begin to realize the benefits from our investment in Westinghouse. We plan to continue to transition to our tier-one cost structure and make the capital and other expenditures we believe are necessary to position the company for continued sustainable growth. Growth that will be sought in the same manner as we approach all aspects of our business; strategic, deliberate, disciplined, and with a focus on generating full-cycle value,” said Tim Gitzel, Cameco’s president and CEO.

“Heightened geopolitical uncertainty, global production shortfalls, and transportation challenges in 2023 further highlighted the growing security of supply risk at a time when we believe the demand outlook is stronger and more durable than ever. The benefits of nuclear power have come clearly into focus, with 28 countries around the world declaring support for the tripling of capacity to help achieve global net-zero greenhouse gas emissions by 2050. The uncertainty about where nuclear fuel supplies will come from to satisfy growing demand has led to increased long-term contracting activity, and in 2023, about 160 million pounds of uranium was placed under long-term contracts by utilities. Prices across the nuclear fuel cycle continued to rise. Spot enrichment prices are up 38% and conversion prices continue to achieve record highs. Uranium spot prices have more than doubled from around $48 (US) per pound at the end of 2022 to $100 (US) per pound at the end of January 2024, after peaking at $106 (US) per pound earlier in the month, and the long-term price for uranium was $72 (US) per pound, an increase of about 38% over the same period.

“We continue to believe that Cameco remains an excellent opportunity to invest in the recovery of the nuclear fuel cycle. We have 35 years of experience in this market and have built a strong reputation as a proven and reliable supplier with a diversified production portfolio that provides us with the flexibility to work with our customers to ensure they maintain access to our reliable supplies to satisfy their ongoing fuel requirements. We have designed our strategy of full-cycle value capture to be resilient. We have multiple supply options, including production, purchases, inventory and loans we can draw on to help ensure we continue to meet our delivery commitments to our customers. Given the nature of our contracts, we have good visibility into when and where we need to deliver material, and we have put in place a number of tools that allow us to self-manage risk.

“We continue to have success gaining and preserving exposure to the improving market fundamentals under long-term contracts that will underpin the sustainable operation of our assets. In our uranium segment, our contracting focus has been on obtaining market-related pricing mechanisms, while also providing adequate downside protection. We continue to be strategically patient in our discussions to maximize value in our contract portfolio and to maintain exposure to higher prices with unencumbered future productive capacity.

“With ongoing improvements in the market, the new long-term contracts we have put in place and our pipeline of contracting discussions, we are planning to produce 18 million pounds (100% basis) at each of McArthur River/Key Lake and Cigar Lake in 2024. We have also converted 73.4 million pounds (100% basis) (40 million pounds our share) of resources to reserves at Cigar Lake, and plan to begin the work necessary to extend the estimated mine life to 2036. At McArthur River/Key Lake, we will undertake an evaluation of the work and investment necessary to expand production up to its annual licensed capacity of 25 million pounds (100% basis), which we expect will allow us to take advantage of this opportunity when the time is right.

“We are excited to have added a 49% interest in Westinghouse to our portfolio of investments in 2023. We believe Westinghouse is well-positioned for long-term growth driven by the expected increase in global demand for nuclear power. In 2024, we expect our share of its adjusted EBITDA to be between $445 million and $510 million. Further, over the next five years, we expect its adjusted EBITDA will grow at a compound annual growth rate of 6% to 10%.

“Thanks to the disciplined execution of our strategy, including our conservative financial management, our balance sheet remains strong. We expect it will enable us to continue executing our strategy and self-managing risk, including risks related to global macro-economic uncertainty and volatility. As of December 31, 2023, we had $567 million in cash and cash equivalents with approximately $1.8 billion in total debt. And, we recently initiated a partial repayment of $200 million (US) on the $600 million (US) floating-rate term loan that was used to finance the acquisition of Westinghouse. Our $1.0 billion credit facility continues to be undrawn.

“With the renewed recognition of the role nuclear power must play in providing clean and secure baseload power, we are optimistic about Cameco’s role in supporting the transition to a net-zero carbon economy. We have a plan to achieve a 30% absolute reduction from our total Scope 1 and 2 emissions level by 2030 from our 2015 baseline, which is the first major milestone on the journey to achieve our ambition of being net-zero. We believe our largest contribution to the net-zero transition comes from the uranium, nuclear fuel, services and technology that we supply to support the generation of nuclear power – 100% carbon-free electricity. Recently, we put further support behind our commitment to climate action and our vision of energizing a clean-air world by joining Net Zero Nuclear, an initiative between government, industry leaders and civil society to triple global nuclear capacity to achieve carbon neutrality by 2050.

“We believe we have the right strategy to achieve our vision of ‘energizing a clean-air world’ and we will do so in a manner that reflects our values. Embedded in all our decisions is a commitment to addressing the environmental, social and governance risks and opportunities that we believe will make our business sustainable over the long term.”

Summary of Q4 and 2023 results and developments:

•

2024 guidance: With the improvements in the market, the new long-term contracts we have put in place, and a pipeline of contracting discussions, our plan is to produce 18 million pounds (100% basis) at each of McArthur River/Key Lake and Cigar Lake in 2024. We also plan to begin the work necessary to extend the estimated mine life at Cigar Lake to 2036. In addition, at McArthur River/Key Lake, we plan to undertake an evaluation of the work and investment necessary to expand production up to its annual licensed capacity of 25 million pounds (100% basis), which we expect will allow us to take advantage of this opportunity when the time is right. Based on Kazatomprom’s (KAP) announcement on February 1, 2024, production in Kazakhstan is expected to remain 20% below the level stipulated in subsoil use agreements, similar to in 2023, primarily due to the sulfuric acid shortage in the country. We are still in discussions with JV Inkai and KAP to determine how this may impact production at Inkai in 2024 and thereafter and therefore our corresponding purchase obligation. At our Port Hope conversion facility, we plan to produce between 13.5 million and 14.5 million kgU, including 12 million kgU of UF₆ to satisfy our book of long-term business for conversion services and customer demand at a time when conversion prices are at historic highs. As a result of these plans, we expect strong financial performance in 2024, including cash flow generation. See Outlook for 2024 and Uranium – Tier-one operations in our 2023 annual MD&A.

•

Fourth quarter net earnings of $80 million; adjusted net earnings of $90 million: Fourth quarter results are driven by normal quarterly variations in contract deliveries and the continued execution of our strategy. Our results include the addition of a new segment with the close of the acquisition of Westinghouse Electric Company (Westinghouse) in the fourth quarter. Adjusted net earnings is a non-IFRS measure, see page 5.

- 2 -

•

Annual net earnings of $361 million; adjusted net earnings of $339 million: Annual results reflect the continued transition back to a tier-one cost structure. Our results also reflect higher sales volumes and the improvement in average realized prices as uranium and conversion prices continued to increase, catalyzed by security of supply concerns. In our uranium segment, we delivered 32 million pounds of uranium at an average realized price of $67.31. Production for 2023 was 17.6 million pounds in our uranium segment, slightly lower than anticipated in September. In our fuel services segment, we delivered 12 million kgU under contract at an average realized price of $35.61 and produced 13.3 million kgU. In addition, we generated $688 million in cash from operations and adjusted EBITDA of $831 million. Our annual results include $101 million in adjusted EBITDA from our investment in Westinghouse. Adjusted net earnings and adjusted EBITDA are non-IFRS measures, see page 5.

•

Disciplined long-term contracting continues: As of December 31, 2023, in our uranium segment, we had commitments requiring delivery of an average of about 27 million pounds of uranium per year from 2024 through 2028, with commitment levels higher than the average in 2024 and 2025, and below the average in 2026 through 2028. Our total portfolio of long-term contracts includes commitments for approximately 205 million pounds of uranium. These commitments only represent about 20% of our current reserve and resource base, providing us with a great deal of exposure to improving demand from our customers as they look to secure their long-term needs. We continue to have a large and growing pipeline of uranium business under discussion. Our focus continues to be on obtaining market-related pricing mechanisms, while also providing adequate downside protection. We continue to be strategically patient in our discussions to maximize value in our contract portfolio and to maintain exposure to higher prices with unencumbered future productive capacity. In addition, with strong demand in the UF₆ conversion market, we were successful in adding new long-term contracts that bring our total contracted volumes to over 75 million kgU of UF₆ that will underpin our Port Hope conversion facility for years to come.

•

JV Inkai shipments: The first shipment containing approximately two thirds of our share of Inkai’s 2023 production was received in the fourth quarter. The second shipment with the remaining volume of our share of 2023 production has arrived at a Canadian port. We continue to work closely with JV Inkai and our joint venture partner, KAP, to receive our share of production via the Trans-Caspian International Transport Route, which does not rely on Russian rail lines or ports. We could experience further delays to our expected Inkai deliveries if transportation using this shipping route takes longer than anticipated. To mitigate the risk of delays, we have inventory, long-term purchase agreements and loan arrangements in place we can draw on to meet our commitments. Depending on when we receive shipments of our share of Inkai’s production, our share of earnings from this equity-accounted investee and the timing of the receipt of our share of dividends from the joint venture may be impacted. See Uranium – Tier-one operations – Inkai in our 2023 annual MD&A.

•

Acquisition of Westinghouse: In November, we announced the closing of the acquisition of Westinghouse in a strategic partnership with Brookfield Asset Management alongside its publicly listed affiliate Brookfield Renewable Partners (Brookfield) and institutional partners. Cameco now owns a 49% interest and Brookfield owns the remaining 51% in Westinghouse. We believe bringing together our expertise in the nuclear industry with Brookfield’s expertise in clean energy positions nuclear power at the heart of the clean energy transition and creates a powerful platform for strategic growth across the nuclear sector. In 2024, we expect our share of its adjusted EBITDA to be between $445 million and $510 million. Further, over the next five years, we expect its adjusted EBITDA will grow at a compound annual growth rate of 6% to 10%. Adjusted EBITDA is a non-IFRS measure, see page 5. See Westinghouse Electric Company in our 2023 annual MD&A.

•

Strong balance sheet: As of December 31, 2023, we had $567 million in cash and cash equivalents and $1.8 billion in total debt. In addition, we have a $1.0 billion undrawn credit facility. We have a $500 million senior unsecured debenture maturing on June 24, 2024. Over the coming months, we will look for an opportunity to refinance this debenture, prior to maturity or as it comes due. Ultimately, our decision will be made with consideration for our cash generation, the interest rate environment and other capital allocation considerations. In addition, we have initiated a partial repayment of $200 million (US) on the $600 million (US) floating-rate term loan that was used to finance the acquisition of Westinghouse. The prepayment will be applied to the $300 million (US) tranche, which matures in November 2026. See Financing Activities in our 2023 annual MD&A for more information about the term loan.

•

Received dividends from JV Inkai: In the first quarter of 2023, we disclosed the receipt of a cash dividend payment from JV Inkai totaling $79 million (US), net of withholdings. JV Inkai distributes excess cash, net of working capital requirements, to the partners as dividends. See Uranium – Tier-one operations – Inkai in our 2023 annual MD&A.

•

Canada Revenue Agency (CRA) tax dispute: In March, we announced CRA issued revised reassessments for the 2007 through 2013 tax years, which resulted in a refund of $297 million of the $780 million in cash and letters of credit held by CRA at the time. The refund consisted of cash in the amount of $86 million and letters of credit in the amount of $211 million, which were returned in the second quarter. In the third quarter MD&A, we disclosed the receipt of $12 million from CRA for disbursements related to costs awarded by the courts, based on their decisions in our favour for the 2003, 2005 and 2006 tax years. The costs were in addition to the $10 million we received from CRA in April 2021 as reimbursement for legal fees. In late 2023, we received a reassessment for the 2017 tax year based on CRA’s alternate reassessing position and expect we will be required to provide letters of credit of about $70 million as security. See Transfer pricing dispute in our 2023 annual MD&A for more information.

•

Licence renewals: In January, the Canadian Nuclear Safety Commission (CNSC) granted a 20-year licence renewal for Cameco Fuel Manufacturing, which also allows for a slight increase to 1,650 tonnes as UO₂ fuel pellets (previously 1,200 tonnes). In October, the CNSC renewed the licences for McArthur River, Key Lake and Rabbit Lake. We were pleased to receive 20-year licences for McArthur River and Key Lake and a 15-year licence for Rabbit Lake. We believe that our commitment to protecting the health and safety of our employees, the public and the environment is reflected in the extended duration of the licences.

Non-IFRS measures

The non-IFRS measures referenced in this document are supplemental measures, which are used as indicators of our financial performance. Management believes that these non-IFRS measures provide useful information to investors, securities analysts, lenders and other interested parties in assessing our operational performance and our ability to generate cash flows to meet our cash requirements. These measures are not recognized measures under IFRS, do not have standardized meanings, and are therefore unlikely to be comparable to similarly-titled measures presented by other companies. Accordingly, these measures should not be considered in isolation or as a substitute for the financial information reported under IFRS. The following are the non-IFRS measures used in this document.

ADJUSTED NET EARNINGS

Adjusted net earnings (ANE) is our net earnings attributable to equity holders, adjusted for non-operating or non-cash items such as gains and losses on derivatives, adjustments to reclamation provisions flowing through other operating expenses, and bargain purchase gains, that we believe do not reflect the underlying financial performance for the reporting period. Other items may also be adjusted from time to time. We do not adjust this measure for items that equity-accounted investees make in arriving at other non-IFRS measures. Adjusted net earnings is one of the targets that we measure to form the basis for a portion of annual employee and executive compensation (see Measuring our results in our 2023 annual MD&A).

- 5 -

In calculating ANE we adjust for derivatives. We do not use hedge accounting under IFRS and, therefore, we are required to report gains and losses on all hedging activity, both for contracts that close in the period and those that remain outstanding at the end of the period. For the contracts that remain outstanding, we must treat them as though they were settled at the end of the reporting period (mark-to-market). However, we do not believe the gains and losses that we are required to report under IFRS appropriately reflect the intent of our hedging activities, so we make adjustments in calculating our ANE to better reflect the impact of our hedging program in the applicable reporting period. See Foreign exchange in our 2023 annual MD&A for more information.

We also adjust for changes to our reclamation provisions that flow directly through earnings. Every quarter we are required to update the reclamation provisions for all operations based on new cash flow estimates, discount and inflation rates. This normally results in an adjustment to our asset retirement obligation asset in addition to the provision balance. When the assets of an operation have been written off due to an impairment, as is the case with our Rabbit Lake and US ISR operations, the adjustment is recorded directly to the statement of earnings as “other operating expense (income)”. See note 16 of our annual financial statements for more information. This amount has been excluded from our ANE measure.

The bargain purchase gain that was recognized when we acquired our pro-rata share of Idemitsu Canada Resources Ltd.’s 7.875% participating interest in the Cigar Lake Joint Venture has also been removed in calculating ANE since it is non-cash, non-operating and outside of the normal course of our business. The gain was recorded in the statement of earnings as part of “other income (expense)”.

As a result of the change in ownership of Westinghouse when they were acquired by Cameco and Brookfield, their inventories at the acquisition date were revalued based on the market price at that date. As these quantities are sold, their cost of products and services sold reflect these market values, regardless of Westinghouse’s historic costs. Since this adjustment is non-cash, outside of the normal course of business and only occurred due to the change in ownership, it has been excluded from our ANE measure.

The following table reconciles adjusted net earnings with our net earnings for the three months and years ended December 31, 2023, and 2022.

EBITDA

EBITDA is defined as net earnings attributable to equity holders, adjusted for the costs related to the impact of the company’s capital and tax structure including depreciation and amortization, finance income, finance costs (including accretion) and income taxes.

ADJUSTED EBITDA

Adjusted EBITDA is defined as EBITDA adjusted for the impact of certain costs or benefits incurred in the period which are either not indicative of the underlying business performance or that impact the ability to assess the operating performance of the business. These adjustments include the amounts noted in the adjusted net earnings definition.

In calculating adjusted EBITDA, we also adjust for items included in the results of our equity-accounted investees. These items are reported as part of marketing, administrative and general expenses within the investee financial information and are not representative of the underlying operations. These include gain/loss on undesignated hedges, transaction costs related to acquisitions and gain/loss on disposition of a business.

- 6 -

We also adjust for the unwinding of the effect of purchase accounting on the sale of inventories which is included in our share of earnings from equity-accounted investee and recorded in the cost of products and services sold in the investee information (see note 12 to the financial statements).

The company may realize similar gains or incur similar expenditures in the future.

EBITDA and adjusted EBITDA are measures which allow us and other users to assess results of operations from a management perspective without regard for our capital structure. To facilitate a better understanding of these measures, the table below reconciles earnings before income taxes with EBITDA and adjusted EBITDA for the years ended 2023 and 2022.

The following Westinghouse financial outlook is reported in Canadian dollars and prepared in accordance with IFRS and reflects Cameco’s 49% ownership share. It reconciles the Westinghouse outlook for net earnings with EBITDA and adjusted EBITDA.


CAMECO SHARE (49%) ($Cdn MILLIONS - IFRS)	2024 OUTLOOK
Net earnings (loss)		(170-230	)
Depreciation and amortization		335-385
Finance income		(2-3	)
Finance costs		140-170
Income tax expense (recovery)		10-30

EBITDA		320-380
Adjustments on cost of products and services sold		55-60
Adjustments on marketing, administrative and general		50-65

Adjusted EBITDA		445-510

The outlook for Westinghouse’s Adjusted EBITDA for 2024 and its growth over the next five years are based on the following assumptions:

•

An exchange rate of $1.00 (US) for $1.30 (Cdn)

•

A compound annual growth rate in revenue from its core business of 4% to 6%, which is slightly higher than the anticipated average growth rate of the nuclear industry based on the World Nuclear Association’s Reference Case. In addition to orders for PWR reactor fuel and services, this includes orders for VVER and BWR fuel and services. The outlook assumes that work is fulfilled on the timelines and scope expected based on current orders received, and additional work is undertaken based on past trends. The expected margins on this work are aligned with the historic margins of 16% to 19%, with variability expected to come from product mix compared to in previous years.

•

Growth from new AP1000^® reactor projects is based on agreements that have been signed and announcements where the AP1000 technology has been selected, including Poland, Bulgaria and Ukraine. It is assumed that work on announced agreements and announced selections to be done by Westinghouse would proceed on the timelines and revenue pattern noted under the New Build Framework. The growth only assumes Westinghouse undertakes the Engineering and Procurement work required prior to a new reactor project breaking ground, which is a small component of the overall potential. A delay in project timelines or cancellation of announced projects would result in a growth rate near the bottom of the range.

•

Estimates and assumptions, including development timelines for both announced and potential reactor builds are subject to government and regulatory approval, as well as risks related to the current macro-economic environment, and may differ significantly from those assumed.

•

We also expect that investments in new technologies, including eVinci^™ microreactor and AP300^™ small modular reactor, will be made in accordance with Westinghouse’s current business plan and are expected to contribute to Westinghouse’s Adjusted EBITDA largely outside the 5-year time frame.

Caution about forward-looking information

This news release includes statements and information about our expectations for the future, which we refer to as forward-looking information. Forward-looking information is based on our current views, which can change significantly, and actual results and events may be significantly different from what we currently expect.

Examples of forward-looking information in this news release include: our expectation of strong financial performance as we begin to realize benefits from our investment in Westinghouse, including our belief that Westinghouse is well-positioned for long-term growth, and our expected share of its adjusted EBITDA for 2024 and over the next five years; our expectation that Westinghouse’s investments in new technologies will be made in accordance with Westinghouse’s current business plan and our expectations regarding the effects on Westinghouse’s adjusted EBITDA; our views regarding supply and demand for nuclear power and its growth across the near, medium and long term; our ability to benefit from market fundamentals and opportunities; the durability of growth in our uranium and conversion services contracting; our ability to operate our assets sustainably, and our expectations regarding the value they will generate for us; our expectations regarding the impact of the completion of a return to a tier-one run rate on our financial results; our views regarding the impact on the nuclear power industry of geopolitical events and ongoing focus on climate crisis; our belief that Cameco is an excellent opportunity to invest in the recovery in the uranium market; the durability of our growth, and our ability to pursue growth and generate full-cycle value; our contract portfolio strategy and ability to maintain exposure to higher prices with unencumbered future productive capacity; our supply plans, including production levels at McArthur River/Key Lake, Cigar Lake and Inkai, as well as at our Port Hope conversion facility; our intention to extend the estimated mine life at Cigar Lake to 2036, our ability to continue to receive production from Inkai without reliance on Russian rail lines or ports and our ability to mitigate the risk of shipment delays; our ability to expand production from our existing assets, and the production level we could achieve through our tier-one expansion opportunities; the factors we will consider in making decisions regarding expanding production; our ability to continue to be resilient; our optimism regarding our role in supporting a transition to a net-zero carbon economy, and expectations regarding our ability to achieve emissions level reductions within our expected timeframes; our vision of energizing a clean-air world and belief in our strategy for doing so in a manner that reflects our values; our expectations regarding refinancing our debenture prior to maturity or as it comes due; our expectations regarding letter of credit requirements in connection with CRA’s reassessment for the 2017 tax year; our views regarding the long-term sustainability of our business and our ability to self-manage risk; and the expected date for announcement of our 2024 first quarter results.

- 10 -

Material risks that could lead to different results include: unexpected changes in uranium supply, demand, long-term contracting, and prices; changes in consumer demand for nuclear power and uranium as a result of changing societal views and objectives regarding nuclear power, electrification and decarbonization; the risk that we may not continue with our supply discipline strategy; risks to Westinghouse’s business associated with potential production disruptions, the implementation of its business objectives, compliance with licensing or quality assurance requirements, or otherwise be unable to achieve expected growth; the risk that we may not be able to implement changes to future operating and production levels for Cigar Lake and McArthur River/Key Lake and Inkai, or at our Port Hope conversion facility, to the planned levels within the expected timeframes, or that the costs involved in doing so, exceed our expectations; the risk that our revenues and cash flows may not improve to the extent expected; the risk of Inkai shipment delays due to the continuation or outcome of the conflict between Ukraine and Russia; the risk that we may not be able to meet sales commitments for any reason; the risk that we may not be able to continue to be resilient or continue to improve our financial performance; the risks to our business associated with potential production disruptions, including those related to global supply chain disruptions, global economic uncertainty and political volatility; the risk that we may not be able to implement our business objectives in a manner consistent with our environmental, social, governance and other values; the risk that the strategy we are pursuing may prove unsuccessful, or that we may not be able to execute it successfully; the risk that we may not be successful in pursuing innovation or implementing advanced technologies; the risk that we may not be able to refinance our debenture on terms that are as favourable as we expect; and the risk that we may be delayed in announcing our future financial results.

In presenting the forward-looking information, we have made material assumptions which may prove incorrect about: uranium demand, supply, consumption, long-term contracting, growth in the demand for and global public acceptance of nuclear energy, and prices; our production, purchases, sales, deliveries and costs; the market conditions and other factors upon which we have based our future plans and forecasts; the success of our plans and strategies, including planned operating and production changes; assumptions about Westinghouse’s production, purchases, sales, deliveries and costs, the absence of business disruptions, and the success of its plans and strategies; the absence of new and adverse government regulations, policies or decisions; that there will not be any significant unanticipated adverse consequences to our business resulting from production disruptions, including those relating to supply disruptions, and economic or political uncertainty and volatility; and our ability to announce future financial results when expected.

Please also review the discussion in our 2023 annual MD&A and most recent annual information form for other material risks that could cause actual results to differ significantly from our current expectations, and other material assumptions we have made. Forward-looking information is designed to help you understand management’s current views of our near-term and longer-term prospects, and it may not be appropriate for other purposes. We will not necessarily update this information unless we are required to by securities laws.

2023 consolidated financial statements

February 7, 2024

Report of management’s accountability

The accompanying consolidated financial statements have been prepared by management in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board. Management is responsible for ensuring that these statements, which include amounts based upon estimates and judgments, are consistent with other information and operating data contained in the annual financial review and reflect the corporation’s business transactions and financial position.

Management is also responsible for the information disclosed in the management’s discussion and analysis including responsibility for the existence of appropriate information systems, procedures and controls to ensure that the information used internally by management and disclosed externally is complete and reliable in all material respects.

In addition, management is responsible for establishing and maintaining an adequate system of internal control over financial reporting. The internal control system includes an internal audit function and a code of conduct and ethics, which is communicated to all levels in the organization and requires all employees to maintain high standards in their conduct of the Company’s affairs. Such systems are designed to provide reasonable assurance that the financial information is relevant, reliable and accurate and that the Company’s assets are appropriately accounted for and adequately safeguarded. Management conducted an evaluation of the effectiveness of the system of internal control over financial reporting based on the criteria established in “Internal Control – Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that the Company’s system of internal control over financial reporting was effective as of December 31, 2023.

KPMG LLP has audited the consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States).

The board of directors annually appoints an audit and finance committee comprised of directors who are not employees of the corporation. This committee meets regularly with management, the internal auditor and the shareholders’ auditors to review significant accounting, reporting and internal control matters. Both the internal and shareholders’ auditors have unrestricted access to the audit and finance committee. The audit and finance committee reviews the consolidated financial statements, the report of the shareholders’ auditors, and management’s discussion and analysis and submits its report to the board of directors for formal approval.

Report of independent registered public accounting firm

To the Shareholders and Board of Directors of Cameco Corporation

Opinion on the consolidated financial statements

We have audited the accompanying consolidated statements of financial position of Cameco Corporation (the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of earnings, comprehensive income, changes in equity and cash flows for each of the years then ended, and the related notes (collectively, the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and its financial performance and its cash flows for each of the years then ended, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated February 7, 2024 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical audit matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit and finance committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Assessment of recoverability of deferred tax assets

As discussed in note 22 to the consolidated financial statements, as of December 31, 2023 the Company has recorded a deferred tax asset of $892,860,000. The realization of this deferred tax asset is dependent on the generation of future taxable income in certain jurisdictions during the periods in which the Company’s deferred tax assets are available. 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. As discussed in note 5D, the calculation of income taxes requires the use of judgment and estimates. The determination of the recoverability of deferred tax assets is dependent on assumptions and judgments regarding future market conditions and production rates, which can materially impact estimated future taxable income.

We identified the assessment of the recoverability of the deferred tax asset as a critical audit matter due to the high degree of judgment required in assessing the significant assumptions and judgments that are reflected in the projections of future taxable income.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s assessment of the recoverability of the deferred tax asset, including controls related to the assumptions and judgments used in the projections of future taxable income. To assess the Company’s ability to estimate future taxable income, we compared the Company’s previous forecasts to actual results. To assess the Company’s estimate of future taxable income, we evaluated certain significant assumptions in the projections. We compared forecast production rates to historical data, board approved budgets and life of mine plans. We involved income tax professionals with specialized skills and knowledge to assist in assessing the Company’s application of the tax regulations in relevant jurisdictions.

Report of independent registered public accounting firm

To the Shareholders and Board of Directors of Cameco Corporation

Opinion on internal control over financial reporting

We have audited Cameco Corporation’s (the “Company”) internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated statements of financial position of the Company as of December 31, 2023 and 2022, the related consolidated statements of earnings, comprehensive income, changes in equity and cash flows for each of the years then ended, and the related notes (collectively, the “consolidated financial statements”) and our report dated February 7, 2024 expressed an unqualified opinion on those consolidated financial statements.

Basis for opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of management’s accountability. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and limitations of internal control over financial reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to consolidated financial statements

For the years ended December 31, 2023 and 2022

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 consolidated financial statements as at and for the year ended December 31, 2023 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 12).

Cameco has two operating mines, Cigar Lake and McArthur River. Operations at McArthur River/Key Lake, which had been suspended in 2018, resumed in November of 2022. 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 29 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 consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB).

These consolidated financial statements were authorized for issuance by the Company’s board of directors on February 7, 2024.

B.	Basis of presentation

These consolidated 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 consolidated 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 consolidated financial statements in conformity with IFRS 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.

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.

This summary of material accounting policies is a description of the accounting methods and practices that have been used in the preparation of these consolidated financial statements and is presented to assist the reader in interpreting the statements contained herein. These accounting policies have been applied consistently to all entities within the consolidated group.

C.	Consolidation principles

i.	Business combinations

The acquisition method of accounting is used to account for the acquisition of subsidiaries by the Company. The Company measures goodwill at the acquisition date as the fair value of the consideration transferred, including the recognized amount of any non-controlling interests in the acquiree, less the net recognized amount (generally fair value) of the identifiable assets acquired and liabilities assumed, all measured as of the acquisition date. When the excess is negative, a bargain purchase gain is recognized immediately in earnings. In a business combination achieved in stages, the acquisition date fair value of the Company’s previously held equity interest in the acquiree is also considered in computing goodwill.

Consideration transferred includes the fair values of the assets transferred, liabilities incurred and equity interests issued by the Company. Consideration also includes the fair value of any contingent consideration and share-based compensation awards that are replaced mandatorily in a business combination.

The Company elects on a transaction-by-transaction basis whether to measure any non-controlling interest at fair value, or at their proportionate share of the recognized amount of the identifiable net assets of the acquiree, at the acquisition date.

Acquisition-related costs are expensed as incurred, except for those costs related to the issue of debt or equity instruments.

ii.

Subsidiaries

The consolidated financial statements include the accounts of Cameco and its subsidiaries. Subsidiaries are entities over which the Company has control. Subsidiaries are fully consolidated from the date on which control is acquired by the Company and are deconsolidated from the date that control ceases.

iii.

Joint arrangements

A joint arrangement can take the form of a joint operation or joint venture. All joint arrangements involve a contractual arrangement that establishes joint control.

A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the assets, and obligations for the liabilities, relating to the arrangement. A joint operation may or may not be structured through a separate vehicle. These arrangements involve joint control of one or more of the assets acquired or contributed for the purpose of the joint operation. The consolidated financial statements of the Company include its share of the assets in such joint operations, together with its share of the liabilities, revenues and expenses arising jointly or otherwise from those operations. All such amounts are measured in accordance with the terms of each arrangement.

A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the arrangement. A joint venture is always structured through a separate vehicle. It operates in the same way as other entities, controlling the assets of the joint venture, earning its own revenue and incurring its own liabilities and expenses. Interests in joint ventures are accounted for using the equity method of accounting, whereby the Company’s proportionate interest in the assets, liabilities, revenues and expenses of jointly controlled entities are recognized on a single line in the consolidated statements of financial position and consolidated statements of earnings. The share of joint ventures results is recognized in the Company’s consolidated financial statements from the date that joint control commences until the date at which it ceases.

When acquiring an additional interest in a joint arrangement, previously held interests are not remeasured at fair value. In an acquisition of an asset or group of assets that does not constitute a business, the directly attributable transaction costs are included in the cost of the asset or group of assets.

iv.

Investments in equity-accounted investees

Cameco’s investments in equity-accounted investees include investments in joint ventures and an associate.

Associates are those entities over which the Company has significant influence, but not control or joint control, over the financial and operating policies. Significant influence is presumed to exist when the Company holds between 20% and 50% of the voting power of another entity but can also arise where the Company holds less than 20% if it has the power to be actively involved and influential in policy decisions affecting the entity. A joint venture is an arrangement in which the Company has joint control, whereby it has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities.

Investments in the joint ventures and associate are accounted for using the equity method. The equity method involves the recording of the initial investment at cost and the subsequent adjusting of the carrying value of the investment for Cameco’s proportionate share of the earnings or loss and OCI and any other changes in the associates’ net assets, such as dividends. The cost of the investment includes transaction costs.

Adjustments are made to align the accounting policies of the joint ventures and associate with those of the Company before applying the equity method. When the Company’s share of losses exceeds its interest in an equity-accounted investee, the carrying amount of that interest is reduced to zero, and the recognition of further losses is discontinued except to the extent that the Company has incurred legal or constructive obligations or made payments on behalf of the associate. If the associate subsequently reports profits, Cameco resumes recognizing its share of those profits only after its share of the profits equals the share of losses not recognized.

v.	Transactions eliminated on consolidation

Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements. Unrealized gains arising from transactions with its equity-accounted investees JV Inkai and Westinghouse are eliminated against the investment to the extent of the Company’s interest in the investee. Unrealized losses are eliminated in the same manner as unrealized gains, but only to the extent that there is no evidence of impairment.

D.	Foreign currency translation

Items included in the financial statements of each of Cameco’s subsidiaries, associates and joint arrangements are measured using their functional currency, which is the currency of the primary economic environment in which the entity operates. The consolidated financial statements are presented in Canadian dollars, which is Cameco’s functional and presentation currency.

i.	Foreign currency transactions

Foreign currency transactions are translated into the respective functional currency of the Company and its entities using the average monthly exchange rates prevailing at the date of the transactions. At the reporting date, monetary assets and liabilities denominated in foreign currencies are translated to the functional currency at the exchange rate at that date. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the average monthly exchange rate at the date of the transaction. The applicable exchange gains and losses arising on these transactions are reflected in earnings with the exception of foreign exchange gains or losses on provisions for decommissioning and reclamation activities that are in a foreign currency, which are capitalized in property, plant and equipment.

ii.

Foreign operations

The assets and liabilities of foreign operations, including goodwill and fair value adjustments arising on acquisition, are translated to Canadian dollars at exchange rates at the reporting dates. The revenues and expenses of foreign operations are translated to Canadian dollars at the average monthly exchange rate at the dates of the transactions.

Foreign currency differences are recognized in other comprehensive income. When a foreign operation is disposed of, in whole, the relevant amount in the foreign currency translation account is transferred to earnings as part of the gain or loss on disposal.

When the settlement of a monetary item receivable from or payable to a foreign operation is neither planned nor likely in the foreseeable future, foreign exchange gains and losses arising from such a monetary item are considered to form part of the net investment in a foreign operation, and are recognized in other comprehensive income and presented within equity in the foreign currency translation account.

E.	Cash and cash equivalents

Cash and cash equivalents consists of balances with financial institutions and investments in money market instruments, which have a term to maturity of three months or less at the time of purchase and are measured at amortized cost.

F.	Short-term investments

Short-term investments are comprised of money market instruments with terms to maturity between three and 12 months and are measured at amortized cost.

G.	Inventories

Inventories of broken ore, uranium concentrates, and refined and converted products are measured at the lower of cost and net realizable value. The cost of inventories is based on the weighted average method.

Cost includes direct materials, direct labour, operational overhead expenses and depreciation. Net realizable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and selling expenses.

Consumable supplies and spares are valued at the lower of cost or replacement value.

H.	Property, plant and equipment

i.	Buildings, plant and equipment and other

Items of property, plant and equipment are measured at cost less accumulated depreciation and impairment charges. The cost of self-constructed assets includes the cost of materials and direct labour, borrowing costs and any other costs directly attributable to bringing the assets to the location and condition necessary for them to be capable of operating in the manner intended by management, including the initial estimate of the cost of dismantling and removing the items and restoring the site on which they are located.

When components of an item of property, plant and equipment have different useful lives, they are accounted for as separate items of property, plant and equipment and depreciated separately.

Gains and losses on disposal of an item of property, plant and equipment are determined by comparing the proceeds from disposal with the carrying amount of property, plant and equipment, and are recognized in earnings.

ii.

Mineral properties and mine development costs

The decision to develop a mine property within a project area is based on an assessment of the commercial viability of the property, the availability of financing and the existence of markets for the product. Once the decision to proceed to development is made, development and other expenditures relating to the project area are deferred as part of assets under construction and disclosed as a component of property, plant and equipment with the intention that these will be depreciated by charges against earnings from future mining operations. No depreciation is charged against the property until the production stage commences. After a mine property has been brought into the production stage, costs of any additional work on that property are expensed as incurred, except for large development programs, which will be deferred and depreciated over the remaining life of the related assets.

The production stage is reached when a mine property is in the condition necessary for it to be capable of operating in the manner intended by management. The criteria used to assess the start date of the production stage are determined based on the nature of each mine construction project, including the complexity of a mine site. A range of factors is considered when determining whether the production stage has been reached, which includes, but is not limited to, the demonstration of sustainable production at or near the level intended (such as the demonstration of continuous throughput levels at or above a target percentage of the design capacity).

iii.

Depreciation

Depreciation is calculated over the depreciable amount, which is the cost of the asset less its residual value. Assets which are unrelated to production are depreciated according to the straight-line method based on estimated useful lives as follows:


Land			Not depreciated
Buildings			15 - 25 years
Plant and equipment			3 - 15 years
Furniture and fixtures			3 - 10 years
Other			3 - 5 years

Mining properties and certain mining and conversion assets for which the economic benefits from the asset are consumed in a pattern which is linked to the production level are depreciated according to the unit-of-production method. For conversion assets, the amount of depreciation is measured by the portion of the facilities’ total estimated lifetime production that is produced in that period. For mining assets and properties, the amount of depreciation or depletion is measured by the portion of the mines’ proven and probable mineral reserves recovered during the period.

Depreciation methods, useful lives and residual values are reviewed at each reporting period and are adjusted if appropriate.

iv.

Repairs and maintenance

The cost of replacing a component of property, plant and equipment is capitalized if it is probable that future economic benefits embodied within the component will flow to the Company. The carrying amount of the replaced component is derecognized. Costs of routine maintenance and repair are charged to products and services sold.

I.	Goodwill and intangible assets

Goodwill arising from the acquisition of subsidiaries is initially recognized at cost, measured as the excess of the fair value of the consideration paid over the fair value of the identifiable net assets acquired. Goodwill is subsequently measured at cost, less accumulated impairment losses.

Intangible assets acquired individually or as part of a group of assets are initially recognized at cost and measured subsequently at cost less accumulated amortization and impairment losses. Subsequent expenditure is capitalized only when it increases the future economic benefits embodied in the specific asset to which it relates. The cost of a group of intangible assets acquired in a transaction, including those acquired in a business combination that meet the specified criteria for recognition apart from goodwill, is allocated to the individual assets acquired based on their relative fair values.

Intangible assets that have finite useful lives are amortized using the units of production method over their estimated remaining useful lives. Amortization methods and useful lives are reviewed at each reporting period and are adjusted if appropriate.

J.	Leases

Cameco recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, which is the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred, less any lease incentives received, and subsequently at cost less any accumulated depreciation and impairment losses. The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the end of the lease term, unless the cost of the right-of-use asset reflects that the Company will exercise a purchase option, in which case the right-of-use asset will be depreciated on the same basis as that of property, plant and equipment.

The lease liability is measured at amortized cost using the effective interest method. It is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease, or, if that rate cannot be readily determined, the Company’s incremental borrowing rate. Generally, Cameco uses its incremental borrowing rate as the discount rate. Current borrowing rates available for classes of leased assets are compared with the rates of Cameco’s existing debt facilities to ensure that use of the Company’s incremental borrowing rate is reasonable.

The lease liability is subsequently increased by the interest cost on the lease liability and decreased by lease payments made. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, a change in the estimate of the amount expected to be payable under a residual value guarantee, or as appropriate, changes in the assessment of whether a purchase or extension option is reasonably certain to be exercised or a termination option is reasonably certain not to be exercised.

Cameco uses judgement in determining the lease term for some lease contracts that include renewal options. The assessment of whether the Company is reasonably certain to exercise such options impacts the lease term, which affects the amount of lease liabilities and right-of-use assets recognized.

The Company has elected not to recognize right-of-use assets and lease liabilities for leases of low-value assets and short-term leases that have a lease term of 12 months or less. The lease payments associated with these leases are recognized as an expense on a straight-line basis over the lease term.

K.	Finance income and finance costs

Finance income comprises interest income on funds invested. Interest income and interest expense are recognized in earnings as they accrue, using the effective interest method. Finance costs are comprised of interest and fees on borrowings and unwinding of the discount on provisions.

Borrowing costs that are not directly attributable to the acquisition, construction or production of a qualifying asset are expensed in the period incurred.

L.	Research and development costs

Expenditures on research are charged against earnings when incurred. Development costs are recognized as assets when the Company can demonstrate technical feasibility and that the asset will generate probable future economic benefits.

M.	Impairment

i.	Non-derivative financial assets

Cameco recognizes loss allowances for expected credit losses (ECLs) on financial assets measured at amortized cost and contract assets. It measures loss allowances at an amount equal to lifetime ECLs, except for debt securities that are determined to have low credit risk at the reporting date and other debt securities, loans advanced and bank balances for which credit risk has not increased significantly since initial recognition. For these, loss allowances are measured equal to 12-month ECLs.

Lifetime ECLs are the ECLs that result from all possible default events over the expected life of a financial instrument while 12-month ECLs are the portion of ECLs that result from default events that are possible within the 12 months after the reporting date (or a shorter period if the expected life of the instrument is less than 12 months). The maximum period considered when estimating ECLs is the maximum contractual period over which the Company is exposed to credit risk.

ECLs are a probability-weighted estimate of credit losses. Credit losses are measured as the present value of the difference between the cash flows due to the entity in accordance with the contract and the cash flows that the Company expects to receive. ECLs are discounted at the effective interest rate of the financial asset.

When determining whether the credit risk of a financial asset has increased significantly since initial recognition and when estimating ECLs, the Company considers reasonable and supportable information that is relevant and available without undue cost or effort. This includes both quantitative and qualitative information and analysis, based on the Company’s historical experience and informed credit assessment and including forward-looking information.

The Company considers a financial asset to be in default when the borrower is unlikely to pay its credit obligations in full, without recourse by Cameco to actions such as realizing security (if any is held).

The Company considers a debt security to have low credit risk when it is at least an A (low) DBRS or A- S&P rating.

Financial assets carried at amortized cost. A financial asset is ‘credit-impaired’ when one or more events that have a detrimental effect on the estimated future cash flows of the financial asset have occurred. Evidence can include significant financial difficulty of the borrower or issuer, a breach of contract, restructuring of an amount due to the Company on terms that the Company would not consider otherwise, indications that a debtor or issuer will enter bankruptcy or other financial reorganization, or the disappearance of an active market for a security.

Loss allowances for financial assets measured at amortized cost are deducted from the gross carrying amount of the assets. The gross carrying amount of a financial asset is written off when the Company has no reasonable expectations of recovering a financial asset in its entirety or a portion thereof.

ii.

Non-financial assets

The carrying amounts of Cameco’s non-financial assets are reviewed throughout the year to determine whether there is any indication of impairment. If any such indication exists, then the asset’s recoverable amount is estimated. Goodwill is tested annually for impairment.

For impairment testing, assets are grouped together into CGUs which are the smallest group of assets that generate cash inflows from continuing use that are largely independent of the cash inflows of other assets or CGUs. Goodwill arising from a business combination is allocated to CGUs or groups of CGUs that are expected to benefit from the synergies of the combination.

The recoverable amount of an asset or CGU is the greater of its value in use and its fair value less costs to sell. Value in use is based on the estimated future cash flows, discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or CGU. Fair value is determined as the amount that would be obtained from the sale of the asset or CGU in an arm’s-length transaction between knowledgeable and willing parties. For exploration properties, fair value is based on the implied fair value of the resources in place using comparable market transaction metrics.

An impairment loss is recognized if the carrying amount of an asset or its CGU exceeds its recoverable amount. Impairment losses are recognized in earnings. Impairment losses recognized in respect of CGUs are allocated first to reduce the carrying amount of any goodwill allocated to the CGU, and then to reduce the carrying amounts of the other assets in the CGU on a pro rata basis.

Impairment losses recognized in prior periods are assessed throughout the year, whenever events or changes in circumstances indicate that the impairment may have reversed. If the impairment has reversed, the carrying amount of the asset is increased to its recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized. A reversal of an impairment loss is recognized immediately in earnings. An impairment loss in respect of goodwill is not reversed.

N.	Exploration and evaluation expenditures

Exploration and evaluation expenditures are those expenditures incurred by the Company in connection with the exploration for and evaluation of mineral resources before the technical feasibility and commercial viability of extracting a mineral resource are demonstrable. These expenditures include researching and analyzing existing exploration data, conducting geological studies, exploratory drilling and sampling, and compiling prefeasibility and feasibility studies. Exploration and evaluation expenditures are charged against earnings as incurred, except when there is a high degree of confidence in the viability of the project and it is probable that these costs will be recovered through future development and exploitation.

Exploration and evaluation costs that have been acquired in a business combination or asset acquisition are capitalized under the scope of IFRS 6, Exploration for and Evaluation of Mineral Resources, and are reported as part of property, plant and equipment.

O.	Provisions

A provision is recognized if, as a result of a past event, the Company has a present legal or constructive obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are determined by discounting the risk-adjusted expected future cash flows at a pre-tax risk-free rate that reflects current market assessments of the time value of money. The unwinding of the discount is recognized as a finance cost.

i.	Environmental restoration

The mining, extraction and processing activities of the Company normally give rise to obligations for site closure and environmental restoration. Closure and restoration can include facility decommissioning and dismantling, removal or treatment of waste materials, as well as site and land restoration. The Company provides for the closure, reclamation and decommissioning of its operating sites in the financial period when the related environmental disturbance occurs, based on the estimated future costs using information available at the reporting date. Costs included in the provision comprise all closure and restoration activity expected to occur gradually over the life of the operation and at the time of closure. Routine operating costs that may impact the ultimate closure and restoration activities, such as waste material handling conducted as a normal part of a mining or production process, are not included in the provision.

The timing of the actual closure and restoration expenditure is dependent upon a number of factors such as the life and nature of the asset, the operating licence conditions and the environment in which the mine operates. Closure and restoration provisions are measured at the expected value of future cash flows, discounted to their present value using a current pre-tax risk-free rate. Significant judgments and estimates are involved in deriving the expectations of future activities and the amount and timing of the associated cash flows.

At the time a provision is initially recognized, to the extent that it is probable that future economic benefits associated with the reclamation, decommissioning and restoration expenditure will flow to the Company, the corresponding cost is capitalized as an asset. The capitalized cost of closure and restoration activities is recognized in property, plant and equipment and depreciated on a unit-of-production basis. The value of the provision is gradually increased over time as the effect of discounting unwinds. The unwinding of the discount is an expense recognized in finance costs.

Closure and rehabilitation provisions are also adjusted for changes in estimates. The provision is reviewed at each reporting date for changes to obligations, legislation or discount rates that effect change in cost estimates or life of operations. The cost of the related asset is adjusted for changes in the provision resulting from changes in estimated cash flows or discount rates, and the adjusted cost of the asset is depreciated prospectively.

ii.

Waste disposal

The refining, conversion and manufacturing processes generate certain uranium-contaminated waste. The Company has established strict procedures to ensure this waste is disposed of safely. A provision for waste disposal costs in respect of these materials is recognized when they are generated. Costs associated with the disposal, the timing of cash flows and discount rates are estimated both at initial recognition and subsequent measurement.

P.	Employee future benefits

i.	Pension obligations

The Company accrues its obligations under employee benefit plans. The Company has both defined benefit and defined contribution plans. A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. A defined benefit plan is a pension plan other than a defined contribution plan.

The liability recognized in the consolidated statements of financial position in respect of defined benefit pension plans is the present value of the defined benefit obligation at the reporting date less the fair value of plan assets. The defined benefit obligation is calculated annually, by qualified independent actuaries using the projected unit credit method prorated on service and management’s best estimate of expected plan investment performance, salary escalation, retirement ages of employees and expected health care costs. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating the terms of the related pension liability.

The Company recognizes all actuarial gains and losses arising from defined benefit plans in other comprehensive income, and reports them in retained earnings. When the benefits of a plan are improved, the portion of the increased benefit relating to past service by employees is recognized immediately in earnings.

For defined contribution plans, the contributions are recognized as employee benefit expense in earnings in the periods during which services are rendered by employees. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in future payments is available.

ii.

Other post-retirement benefit plans

The Company provides certain post-retirement health care benefits to its retirees. The entitlement to these benefits is usually conditional on the employee remaining in service up to retirement age and the completion of a minimum service period. The expected costs of these benefits are accrued over the period of employment using the same accounting methodology as used for defined benefit pension plans. Actuarial gains and losses are recognized in other comprehensive income in the period in which they arise. These obligations are valued annually by independent qualified actuaries.

iii.

Short-term employee benefits

Short-term employee benefit obligations are measured on an undiscounted basis and are expensed as the related service is provided. A liability is recognized for the amount expected to be paid under short-term cash bonus plans if the Company has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee, and the obligation can be measured reliably.

iv.

Termination benefits

Termination benefits are payable when employment is terminated by the Company before the normal retirement date, or whenever an employee accepts an entity’s offer of benefits in exchange for termination of employment. Cameco recognizes termination benefits as an expense at the earlier of when the Company can no longer withdraw the offer of those benefits and when the Company recognizes costs for a restructuring. If benefits are payable more than 12 months after the reporting period, they are discounted to their present value.

v.	Share-based compensation

For equity-settled plans, the grant date fair value of share-based compensation awards granted to employees is recognized as an employee benefit expense, with a corresponding increase in equity, over the period that the employees unconditionally become entitled to the awards. The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and vesting conditions are expected to be met, such that the amount ultimately recognized as an expense is based on the number of awards that meet the related service and non-market performance conditions at the vesting date.

For cash-settled plans, the fair value of the amount payable to employees is recognized as an expense, with a corresponding increase in liabilities, over the period that the employees unconditionally become entitled to payment. The liability is re-measured at each reporting date and at settlement date. Any changes in the fair value of the liability are recognized as employee benefit expense in earnings.

When the terms and conditions of equity-settled plans at the time they were granted are subsequently modified, the fair value of the share-based payment under the original terms and conditions and under the modified terms and conditions are both determined at the date of the modification. Any excess of the modified fair value over the original fair value is recognised over the remaining vesting period in addition to the grant date fair value of the original share-based payment. The share-based payment expense is not adjusted if the modified fair value is less than the original fair value.

Cameco’s contributions under the employee share ownership plan are expensed during the year of contribution. Shares purchased with Company contributions and with dividends paid on such shares become unrestricted on January 1 of the second plan year following the date on which such shares were purchased.

Q.	Revenue recognition

Cameco supplies uranium concentrates, uranium conversion services, fabrication services and other services. Revenue is measured based on the consideration specified in a contract with a customer. The Company recognizes revenue when it transfers control, as described below, over a good or service to a customer. Customers do not have the right to return products, except in limited circumstances.

Cameco’s sales arrangements with its customers are pursuant to enforceable contracts that indicate the nature and timing of satisfaction of performance obligations, including significant payment terms, where payment is usually due in 30 days. Each delivery is considered a separate performance obligation under the contract.

Uranium supply

In a uranium supply arrangement, Cameco is contractually obligated to provide uranium concentrates to its customers. Cameco-owned uranium may be physically delivered to either the customer or to conversion facilities (Converters).

For deliveries to customers, terms in the sales contract specify the location of delivery. Revenue is recognized when the uranium has been delivered and accepted by the customer at that location.

When uranium is delivered to Converters, the Converter will credit Cameco’s account for the volume of accepted uranium. Based on delivery terms in the sales contract with its customer, Cameco instructs the Converter to transfer title of a contractually specified quantity of uranium to the customer’s account at the Converter’s facility. At this point, control has been transferred and Cameco recognizes revenue for the uranium supply.

Toll conversion services

In a toll conversion arrangement, Cameco is contractually obligated to convert customer-owned uranium to a chemical state suitable for enrichment. Based on delivery terms in a sales contract with its customer, Cameco either (i) physically delivers converted uranium to enrichment facilities (Enrichers) where it instructs the Enricher to transfer title of a contractually specified quantity of converted uranium to the customer’s account at the Enricher’s facility, or (ii) transfers title of a contractually specified quantity of converted uranium to either an Enricher’s account or the customer’s account at Cameco’s Port Hope conversion facility. At this point, the customer obtains control and Cameco recognizes revenue for the toll conversion services.

Conversion supply

A conversion supply arrangement is a combination of uranium supply and toll conversion services. Cameco is contractually obligated to provide converted uranium to its customers. Based on delivery terms in the sales contract, Cameco either (i) physically delivers converted uranium to the Enricher where it instructs the Enricher to transfer title of a contractually specified quantity of converted uranium to the customer’s account at the Enricher’s facility, or (ii) transfers title of a contractually specified quantity of converted uranium to either an Enricher’s account or a customer’s account at Cameco’s Port Hope conversion facility. At this point, the customer obtains control and Cameco recognizes revenue for both the uranium supplied and the conversion service provided.

Fabrication services

In a fabrication services arrangement, Cameco is contractually obligated to provide fuel bundles or reactor components to its customers. In a contract for fuel bundles, the bundles are inspected and accepted by the customer at Cameco’s Port Hope fabrication facility or another location based on delivery terms in the sales contract. At this point, the customer obtains control and Cameco recognizes revenue for the fabrication services.

In some contracts for reactor components, the components are made to a customer’s specification and if a contract is terminated by the customer, Cameco is entitled to reimbursement of the costs incurred to date, including a reasonable margin. Since the customer controls all of the work in progress as the products are being manufactured, revenue and associated costs are recognized over time, before the goods are delivered to the customer’s premises. Revenue is recognized on the basis of units produced as the contracts reflect a per unit basis. Revenue from these contracts represents an insignificant portion of Cameco’s total revenue. In other contracts where the reactor components are not made to a specific customer’s specification, when the components are delivered to the location specified in the contract, the customer obtains control and Cameco recognizes revenue for the services.

Other services

Uranium concentrates and converted uranium are regulated products and can only be stored at regulated facilities. In a storage arrangement, Cameco is contractually obligated to store uranium products at its facilities on behalf of the customer. Cameco invoices the customer in accordance with the contract terms and recognizes revenue on a monthly basis.

Cameco also provides customers with transportation of its uranium products. In the contractual arrangements where Cameco is acting as the principal, revenue is recognized as the product is delivered.

R.	Financial instruments

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another.

Trade receivables and debt securities are initially recognized when they are originated. All other financial assets and liabilities are initially recognized when the company becomes a party to the contractual provisions of the instrument. A financial asset (unless it is a trade receivable without a significant financing component) or financial liability is initially measured at fair value plus, for an item not at fair value through profit or loss, transaction costs that are directly attributable to its acquisition or issue. A trade receivable without a significant financing component is initially measured at the transaction price.

i.	Financial assets

On initial recognition, financial assets are classified as measured at: amortized cost, fair value through other comprehensive income, or fair value through profit or loss based on the Company’s business model for managing its financial assets and their cash flow characteristics. Classifications are not changed subsequent to initial recognition unless the Company changes its business model for managing its financial assets, in which case all affected financial assets are reclassified on the first day of the first reporting period following the change in business model.

Amortized cost

A financial asset is measured at amortized cost if it is not designated as at fair value through profit or loss, is held within a business model whose objective is to hold assets to collect contractual cash flows and its contractual terms give rise to cash flows on specified dates that are solely payments of principal and interest on the principal amount outstanding. Assets in this category are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss, as is any gain or loss on derecognition. The Company’s financial assets measured at amortized cost include cash and cash equivalents, short-term investments and accounts receivable.

Fair value through other comprehensive income (FVOCI)

A debt investment is measured at FVOCI if it is not designated as at fair value through profit or loss, is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets and its contractual terms give rise to cash flows on specified dates that are solely payments of principal and interest on the principal amount outstanding. These assets are subsequently measured at fair value. Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses are recognized in other comprehensive income (OCI). On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss.

On initial recognition of an equity investment that is not held for trading, Cameco may irrevocably elect to present subsequent changes in the investments fair value in OCI. This election is made on an investment-by-investment basis. These assets are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of part of the cost of the investment. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss.

Fair value through profit or loss (FVTPL)

All financial assets not classified as measured at amortized cost or FVOCI are measured at FVTPL. This includes all derivative financial assets. On initial recognition, the Company may irrevocably designate a financial asset that otherwise meets the requirements to be measured at amortized cost or at FVOCI as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise. These assets are subsequently measured at fair value. Net gains and losses, including any interest or dividend income, are recognized in profit or loss. The Company’s financial assets measured at FVTPL include foreign currency contracts.

Derecognition of financial assets

Cameco derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred or in which it neither transfers or retains substantially all of the risks and rewards of ownership and it does not retain control of the financial asset.

If the Company enters into a transaction whereby it transfers assets recognized in its statement of financial position, but retains either all or substantially all of the risks and rewards of the transferred assets, the transferred assets would not be derecognized.

ii.

Financial liabilities

On initial recognition, financial liabilities are classified as measured at amortized cost or FVTPL. A financial liability is classified as FVTPL if it is classified as held-for-trading, is a derivative or is designated as such on initial recognition. Financial liabilities at FVTPL are measured at fair value and net gains and losses, including any interest expense, are recognized in profit or loss. Other financial liabilities are subsequently measured at amortized cost using the effective interest method. Interest expense and foreign exchange gains and losses are recognized in profit or loss as is any gain or loss on derecognition. The Company’s financial liabilities measured at amortized cost include accounts payable and accrued liabilities, lease obligations and long-term debt. The Company’s financial liabilities measured at FVTPL include foreign currency contracts and interest rate contracts.

A financial liability is derecognized when its contractual obligations are discharged or cancelled, or expire. The Company also derecognizes a financial liability when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value. On derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including any non-cash assets transferred or liabilities assumed) is recognized in profit or loss.

iii.

Derivative financial instruments

The Company holds derivative financial instruments to reduce exposure to fluctuations in foreign currency exchange rates and interest rates. Embedded derivatives are separated from the host contract and accounted for separately if the host contract is not a financial asset and certain criteria are met.

Derivative financial instruments are initially measured at fair value in the consolidated statements of financial position, with any directly attributable transaction costs recognized in profit or loss as incurred. Subsequent to initial recognition, derivatives are measured at fair value, and changes in fair value are recognized in profit or loss.

The purpose of hedging transactions is to modify the Company’s exposure to one or more risks by creating an offset between changes in the fair value of, or the cash flows attributable to, the hedged item and the hedging item. When hedge accounting is appropriate, the hedging relationship is designated as a fair value hedge, a cash flow hedge, or a foreign currency risk hedge related to a net investment in a foreign operation. While Cameco does not have any instruments that have been designated as hedge transactions at December 31, 2023 and 2022, its equity-investee Westinghouse does. These cash flow hedges are recognized in other comprehensive income.

S.	Income tax

Income tax expense is comprised of current and deferred taxes. Current tax and deferred tax are recognized in earnings except to the extent that it relates to a business combination, or items recognized directly in equity or in other comprehensive income.

Current tax is the expected tax payable or receivable on the taxable income or loss for the year, using tax rates enacted or substantively enacted at the reporting date, and any adjustments to tax payable in respect of previous years. Current tax assets and liabilities are measured at the amount expected to be paid or recovered from the taxation authorities.

Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. In addition, deferred tax is not recognized for taxable temporary differences arising on the initial recognition of goodwill. Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, based on the laws that have been enacted or substantively enacted by the reporting date. Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax liabilities and assets, and they relate to income taxes levied by the same tax authority on the same taxable entity, or on different tax entities, but they intend to settle current tax liabilities and assets on a net basis or their tax assets and liabilities will be realized simultaneously.

A deferred tax asset is recognized for unused tax losses, tax credits and deductible temporary differences, to the extent that it is probable that future taxable income will be available against which they can be utilized. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized.

The Company’s exposure to uncertain tax positions is evaluated and a provision is made where it is probable that this exposure will materialize.

T.	Share capital

Common shares are classified as equity. Incremental costs directly attributable to the issue of common shares are recognized as a reduction of equity, net of any tax effects.

U.	Earnings per share

The Company presents basic and diluted earnings per share data for its common shares. Earnings per share is calculated by dividing the net earnings attributable to equity holders of the Company by the weighted average number of common shares outstanding.

Diluted earnings per share is determined by adjusting the net earnings attributable to equity holders of the Company and the weighted average number of common shares outstanding, for the effects of all dilutive potential common shares. The calculation of diluted earnings per share assumes that outstanding options which are dilutive to earnings per share are exercised and the proceeds are used to repurchase shares of the Company at the average market price of the shares for the period. The effect is to increase the number of shares used to calculate diluted earnings per share.

V.	Segment reporting

An operating segment is a component of the Company that engages in business activities from which it may earn revenues and incur expenses, including revenues and expenses that relate to transactions with any of the Company’s other segments. To be classified as a segment, discrete financial information must be available and operating results must be regularly reviewed by the Company’s executive team. Cameco has three reportable segments, uranium, fuel services and Westinghouse.

Segment capital expenditure is the total cost incurred during the period to acquire property, plant and equipment, and intangible assets other than goodwill.

3.	Accounting standards

A.	Changes in accounting policy

A number of amendments to existing standards became effective January 1, 2023 but they did not have a material effect on the Company’s financial statements.

i.	Income taxes

In May 2023, the International Accounting Standards Board (IASB) issued International Tax Reform – Pillar Two Model Rules, which amended IAS 12, Income Taxes (IAS 12). The amendments are effective for annual periods beginning on or after January 1, 2023. The amendments apply to income taxes arising from changes to tax law enacted to implement the Pillar Two model rules published by the Organisation for Economic Co-operation and Development. Cameco applied the temporary mandatory exception from deferred tax accounting for the top-up tax related to Pillar Two income taxes. We have not included additional disclosures arising from this amendment in these consolidated annual financial statements for the year ended December 31, 2023 because the impact was not material.

ii.

Disclosure of accounting policies

In February 2021, the IASB issued an amendment to IAS 1, Disclosure of Accounting Policies (IAS 1). The amendment was effective for annual reporting periods beginning on or after January 1, 2023 and provided requirements and guidance to help entities make more effective accounting policy disclosures. We have reviewed our disclosures in note 2 and amended them to only include accounting policy information that we considered material based on the new guidance.

B.	New standards and interpretations not yet adopted

A number of amendments to existing standards are not yet effective for the year ended December 31, 2023 and have not been applied in preparing these consolidated financial statements. Cameco does not intend to early adopt any of the amendments and does not expect them to have a material impact on its financial statements.

4.	Determination of fair values

A number of the Company’s accounting policies and disclosures require the measurement of fair value, for both financial and non-financial assets and liabilities.

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.

Transfers between levels of the fair value hierarchy are recognized at the end of the reporting period during which the transfer occurred. There were no transfers between level 1, level 2, or level 3 during the period. Cameco does not have any recurring fair value measurements that are categorized as level 3 as of the reporting date.

Further information about the techniques and assumptions used to measure fair values is included in the following notes:

Note 6 - Acquisitions

Note 25 - Share-based compensation plans

Note 27 - Financial instruments and risk management

5.	Use of estimates and judgments

The preparation of the consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenues and expenses. Actual results may differ from these estimates.

Information about critical judgments in applying the accounting policies that have the most significant effect on the amounts recognized in the consolidated financial statements is discussed below. Further details of the nature of these judgments, estimates and assumptions may be found in the relevant notes to the consolidated financial statements.

A.	Recoverability of long-lived and intangible assets and investments

Cameco assesses the carrying values of property, plant and equipment, intangible assets and investments in associates and joint ventures when there is an indication of possible impairment. If it is determined that carrying values of assets cannot be recovered, the unrecoverable amounts are charged against current earnings. Recoverability is dependent upon assumptions and judgments regarding market conditions, costs of production, sustaining capital requirements, mineral reserves and the impact of geopolitical events. Other assumptions used in the calculation of recoverable amounts are discount rates, future cash flows and profit margins. A material change in assumptions may significantly impact the potential impairment of these assets.

B.	Cash generating units

In performing impairment assessments of long-lived assets, assets that cannot be assessed individually are grouped together into the smallest group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. Management is required to exercise judgment in identifying these CGUs.

C.	Provisions for decommissioning and reclamation of assets

Significant decommissioning and reclamation activities are often not undertaken until near the end of the useful lives of the productive assets. Regulatory requirements and alternatives with respect to these activities are subject to change over time. A significant change to either the estimated costs, timing of the cash flows or mineral reserves may result in a material change in the amount charged to earnings.

D.	Income taxes

Cameco operates in a number of tax jurisdictions and is, therefore, required to estimate its income taxes in each of these tax jurisdictions in preparing its consolidated financial statements. In calculating income taxes, consideration is given to factors such as tax rates in the different jurisdictions, non-deductible expenses, changes in tax law and management’s expectations of future operating results. Cameco estimates deferred income taxes based on temporary differences between the income and losses reported in its consolidated financial statements and its taxable income and losses as determined under the applicable tax laws. The tax effect of these temporary differences is recorded as deferred tax assets or liabilities in the consolidated financial statements. The calculation of income taxes requires the use of judgment and estimates. The determination of the recoverability of deferred tax assets is dependent on assumptions and judgments regarding future market conditions and production rates, which can materially impact estimated future taxable income. If these judgments and estimates prove to be inaccurate, future earnings may be materially impacted.

E.	Mineral reserves

Depreciation on property, plant and equipment is primarily calculated using the unit-of-production method. This method allocates the cost of an asset to each period based on current period production as a portion of total lifetime production or a portion of estimated mineral reserves. Estimates of life-of-mine and amounts of mineral reserves are updated annually and are subject to judgment and significant change over time. If actual mineral reserves prove to be significantly different than the estimates, there could be a material impact on the amounts of depreciation charged to earnings.

6.	Acquisitions

A.	Westinghouse Electric Company (Westinghouse)

On November 7, 2023, Cameco acquired a 49% interest in Westinghouse, one of the world’s largest nuclear services businesses, in partnership with Brookfield Asset Management alongside its publicly listed affiliate Brookfield Renewable Partners (Brookfield) and its institutional partners. Brookfield, with its institutional partners, owns the other 51%. The acquisition represents an investment in additional nuclear fuel cycle assets that the Company expects will augment the core of its business.

To finance its 49% share of the purchase price, $2,140,305,000 (US), Cameco used a combination of cash, debt and equity. The Company used $1,540,305,000 (US) of cash and $600,000,000 (US) in term loans (see note 14). In 2022, Cameco had issued 34,057,250 common shares pursuant to a public offering to help fund the acquisition (see note 17). At December 31, 2023, $50,000,000 (US) remained in escrow, to be paid upon finalization of the closing statement.

The purchase price was allocated to the underlying assets and liabilities assumed based on their fair values at the date of acquisition. The values assigned to Cameco’s share of the net assets acquired were as follows:


Net assets acquired (USD)
Cash and cash equivalents	$	254,800
Other current assets		938,413
Property, plant and equipment		787,278
Intangible assets		2,852,780
Goodwill		568,631
Non-current assets		346,891
Current liabilities		(1,164,621	)
Non-current liabilities		(2,443,867	)

Total	$	2,140,305

Cash		1,540,305
Term loans [note 14]		600,000

Total	$	2,140,305

Fair values were determined using a number of different valuation methodologies depending on the characteristics of the assets being valued. Methods included discounted cash flows, relief from royalty and multi-period excess earnings, quoted market prices and the direct cost method.

Intangible assets include customer relationships and contracts, developed technology, the Westinghouse trade name and product development costs. Goodwill reflects the value assigned to the expected future earnings capabilities of the organization. This is the earnings potential that we anticipate will be realized through new business arrangements.

The valuation of the assets and liabilities assumed was not finalized as of the date of these financial statements. The accounting for the acquisition will be revised when the valuation is complete. Following the completion of the valuation, if new information obtained within one year of the acquisition date about facts and circumstances that existed at the date of acquisition, identifies adjustments to the above amounts, or any additional provisions that existed at the date of acquisition, further revisions will be made.

B.	Additional interest in Cigar Lake Joint Venture (CLJV)

On May 19, 2022, Cameco and Orano Canada Inc. (Orano) completed the acquisition of Idemitsu Canada Resources Ltd.’s (Idemitsu) 7.875% 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 54.547% (previously 50.025%). The primary reason for the business combination was to increase our ownership interest.

Cash consideration of $101,681,000 was paid for the additional 4.522% interest. While Cameco received the economic benefit of owning the additional interest as of January 1, 2022, the additional interest has been proportionately consolidated with the results of Cameco commencing on May 19, 2022.

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 296,000 pounds. The impact to the financial statements would not have been material.

Acquisition costs of $1,495,000 have been included in administration expense in the consolidated statements of earnings for the year ended December 31, 2022.

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	$	97,930
Deferred tax asset		28,196
Inventory		9,909
Working capital		(24	)
Reclamation provision		(2,528	)
Sales contracts		(9,000	)

Net assts acquired	$	124,483

Cash paid		101,681

Bargain purchase gain [note 21]^(a)	$	22,802

(a)

The bargain purchase gain resulted from applying the measurement requirements under IFRS 3, Business Combinations. This standard requires the measurement of tax attributes that were acquired as part of the transaction be in accordance with IAS 12, Income Taxes, rather than at fair value. The measured amount of these attributes exceeded the amount paid for them and the resulting gain is included in other income (expense) in the consolidated statement of earnings.

7.	Accounts receivable


	2023		2022
Trade receivables	$	413,792	$	167,688
GST/VAT receivables		6,772		5,856
Other receivables		1,769		10,400

Total	$	422,333	$	183,944

The Company’s exposure to credit and currency risks as well as credit losses related to trade and other receivables, excluding goods and services tax (GST)/value added tax (VAT) receivables, is disclosed in note 27.

8.	Inventories


	2023		2022
Uranium
Concentrate	$	511,654	$	537,426

Cameco has contractual capital commitments of approximately $60,525,000 at December 31, 2023. Certain of the contractual commitments may contain cancellation clauses, however the Company discloses the commitments based on management’s intent to fulfill the contract. The majority of this amount is expected to be incurred in 2024.

(a)

Asset retirement obligation assets are adjusted when the Company updates its reclamation provisions due to new cash flow estimates or changes in discount and inflation rates. When the assets of an operation have been written off due to an impairment, as is the case with our Rabbit Lake operation and some of our operations in the United States, the adjustment is recorded directly to the statement of earnings as other operating expense or income.

Cameco was 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. $86,097,000 was received during the year (see note 22).

(b)

Cameco loaned 5,400,000 pounds of uranium concentrate to its joint venture partner, Orano Canada Inc., (Orano). Orano was obligated to repay the Company in kind with uranium concentrate no later than December 31, 2023. During 2022, the repayment terms were extended to December 31, 2028. As at December 31, 2023, 3,000,000 pounds have been returned as repayment on this loan.

Cameco also agreed to lend to Orano up to 1,148,200 kgU of conversion supply and up to an additional 1,200,000 pounds of uranium concentrate over the period 2022 to 2024. Repayment to Cameco is to be made in kind with U₃O₈ quantities drawn being repaid by December 31, 2027 and quantities of UF₆ drawn by December 31, 2035.

As at December 31, 2023, 3,600,000 pounds of U₃O₈ (December 31, 2022 - 3,571,001 pounds) and 1,148,200 kgU of UF₆ conversion supply (December 31, 2022 - 700,000 kgU) were drawn on the loans and are recorded at Cameco’s weighted average cost of inventory.

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. Effective November 7, 2023, 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.

The following table summarizes the total comprehensive loss of Westinghouse (100%) for the period commencing November 7, 2023:

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 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 table summarizes the total comprehensive earnings of JV Inkai (100%):

Cameco has a $1,000,000,000 unsecured revolving credit facility that is available until October 1, 2027. Upon mutual agreement, the facility can be extended for an additional year on the anniversary date. In addition to direct borrowings under the facility, up to $100,000,000 can be used for the issuance of letters of credit and, to the extent necessary, it may be used to provide liquidity support for the Company’s commercial paper program. The agreement also provides the ability to increase the revolving credit facility above $1,000,000,000 by increments no less than $50,000,000, to a total of $1,250,000,000. The facility ranks equally with all of Cameco’s other senior debt. As of December 31, 2023 and 2022, there were no amounts outstanding under this facility.

Cameco has $1,771,663,000 (2022 - $1,756,754,000) in letter of credit facilities. Outstanding and committed letters of credit at December 31, 2023 amounted to $1,383,689,000 (2022 - $1,593,379,000), the majority of which relate to future decommissioning and reclamation liabilities (note 16).

On November 7, 2023, the Company utilized a term loan for $600,000,000 (US) with a syndicate of lenders. The proceeds of the term loan were used to finance the 49% acquisition of Westinghouse. The term loan consists of two $300,000,000 (US) tranches. The first tranche has a floating interest rate of SOFR plus 1.80% and matures on November 7, 2025. The second tranche has a floating interest rate of SOFR plus 2.05% and matures on November 7, 2026.

Cameco is bound by a covenant in its revolving credit facility and term loan. The covenant requires a funded debt to tangible net worth ratio equal to or less than 1:1. Non-compliance with this covenant could result in accelerated payment and termination of the revolving credit facility and term loan. At December 31, 2023, Cameco was in compliance with the covenant and does not expect its operating and investing activities in 2024 to be constrained by it.

The table below represents currently scheduled maturities of long-term debt:

A.	Reclamation provision

Cameco’s estimates of future decommissioning obligations are based on reclamation standards that satisfy regulatory requirements. Elements of uncertainty in estimating these amounts include potential changes in regulatory requirements, decommissioning and reclamation alternatives and amounts to be recovered from other parties.

Cameco estimates total undiscounted future decommissioning and reclamation costs for its existing operating assets to be $1,356,018,000 (2022 - $1,356,092,000). The expected timing of these outflows is based on life-of-mine plans with the majority of expenditures expected to occur after 2027. These estimates are reviewed by Cameco technical personnel as required by regulatory agencies or more frequently as circumstances warrant. In connection with future decommissioning and reclamation costs, Cameco has provided financial assurances of $1,060,769,000 (2022 - $1,035,348,000) in the form of letters of credit to satisfy current regulatory requirements.

The reclamation provision relates to the following segments:


	2023		2022
Uranium	$	874,773	$	870,877
Fuel services		176,394		190,219

Total	$	1,051,167	$	1,061,096

B.	Waste disposal

The fuel services segment consists of the Blind River refinery, Port Hope conversion facility and Cameco Fuel Manufacturing Inc.. The refining, conversion and manufacturing processes generate certain uranium contaminated waste. These include contaminated combustible material (paper, rags, gloves, etc.) and contaminated non-combustible material (metal parts, soil from excavations, building and roofing materials, spent uranium concentrate drums, etc.). These materials can in some instances be recycled or reprocessed. A provision for waste disposal costs in respect of these materials is recognized when they are generated.

Cameco estimates total undiscounted future costs related to existing waste disposal to be $9,681,000 (2022 - $8,919,000). The majority of these expenditures are expected to occur within the next three years.

A.	Common Shares


Number issued (number of shares)	2023		2022
Beginning of year		432,518,470		398,059,265

(a)	On October 17, 2022, Cameco issued 34,057,250 common shares pursuant to a public offering for a total consideration of $996,867,000. The proceeds of the issue after deducting expenses were $964,878,000. Excluding the deferred tax recoveries, the net cash proceeds amounted to $953,285,000.

All issued shares are fully paid. Holders of the common shares are entitled to exercise one vote per share at meetings of shareholders, are entitled to receive dividends if, as and when declared by our Board of Directors and are entitled to participate in any distribution of remaining assets following a liquidation.

The shares of Cameco are widely held and no shareholder, resident in Canada, is allowed to own more than 25% of the Company’s outstanding common shares, either individually or together with associates. A non-resident of Canada is not allowed to own more than 15%. In addition, no more than 25% of total shareholder votes cast may be cast by non-resident shareholders.

B.	Class B share

One Class B share issued during 1988 and assigned $1 of share capital entitles the shareholder to vote separately as a class in respect of any proposal to locate the head office of Cameco to a place not in the province of Saskatchewan.

C.	Dividends

Dividends on Cameco Corporation common shares are declared in Canadian dollars. For the year ended December 31, 2023, the dividend declared per share was $0.12 (December 31, 2022 - $0.12).

18.

Revenue

Cameco’s 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 table summarizes Cameco’s sales disaggregated by geographical region and contract type and includes a reconciliation to the Company’s reportable segments (note 29):

Deferred sales

The following table provides information about contract liabilities (note 15) from contracts with customers:


	2023			2022
Beginning of year	$	66,845		$	23,316
Additions		25,935			45,978
Recognized in revenue		(47,403	)		(2,463	)
Effect of movements in exchange rates		(5	)		14

End of year	$	45,372		$	66,845

Deferred sales primarily relates to advance consideration received from customers for future uranium and conversion deliveries as well as revenue related to the storage of uranium and converted uranium held at Cameco facilities. The revenue related to storage is recognized over time while the revenue related to future uranium and conversion deliveries is expected to be recognized between 2024 and 2030.

Cameco recognized a decrease of revenue of $648,000 (2022 - decrease of revenue of $194,000) during 2023 from performance obligations satisfied (or partially satisfied) in previous periods. This is due to the difference between actual pricing indices and the estimates at the time of invoicing.

Future sales commitments

Cameco’s sales portfolio consists of short and long-term sales commitments. The contracts can be executed well in advance of a delivery and include both fixed and market-related pricing. The following table summarizes the expected future revenue, by segment, related to only fixed-price contracts with remaining future deliveries as follows:


	2024		2025		2026		2027		2028		Thereafter		Total
Uranium	$	676,996	$	756,597	$	406,045	$	367,194	$	349,872	$	565,998	$	3,122,702
Fuel services		356,742		397,922		383,045		356,792		333,166		1,474,806		3,302,473

Total	$	1,033,738	$	1,154,519	$	789,090	$	723,986	$	683,038	$	2,040,804	$	6,425,175

The sales contracts are denominated largely in US dollars and converted from US to Canadian dollars at a rate of $1.30.

The amounts in the table represent the consideration the Company will be entitled to receive when it satisfies the remaining performance obligations in the contracts. The amounts include assumptions about volumes for contracts that have volume flexibility. Cameco’s total revenue that will be earned will also include revenue from contracts with market-related pricing. The Company has elected to exclude these amounts from the table as the transaction price will not be known until the time of delivery. Contracts with an original duration of one year or less have been included in the table.

Cameco has recorded a deferred tax asset of $892,860,000 (2022 - $984,071,000). The realization of this deferred tax asset 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.

F.	Reassessments

Canada

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. Due to a revised CRA reassessment position for certain years, CRA has released approximately $86,000,000 of cash held on account (see note 11).

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.

G.	Income tax losses

At December 31, 2023, income tax losses carried forward of $1,760,518,000 (2022 - $2,171,825,000) are available to reduce taxable income. These losses expire as follows:

Included in the table above is $1,447,529,000 (2022 - $1,329,261,000) of temporary differences related to loss carry forwards where no future benefit has been recognized.

23. Per share amounts

Per share amounts have been calculated based on the weighted average number of common shares outstanding during the period. The weighted average number of paid shares outstanding in 2023 was 433,382,879 (2022 - 405,494,353).


	2023		2022
Basic earnings per share computation
Net earnings attributable to equity holders	$	360,847	$	89,382
Weighted average common shares outstanding		433,383		405,494

Basic earnings per common share	$	0.83	$	0.22

Diluted earnings per share computation
Net earnings attributable to equity holders	$	360,847	$	89,382
Weighted average common shares outstanding		433,383		405,494
Dilutive effect of stock options		1,972		1,641

Weighted average common shares outstanding, assuming dilution		435,355		407,135

Diluted earnings per common share	$	0.83	$	0.22

In both 2023 and 2022, there were no options excluded from the diluted weighted average number of common shares because their inclusion would have been anti-dilutive.

Share-based compensation plans

The Company has the following plans:

A.	Stock option plan

The Company has established a stock option plan under which options to purchase common shares may be granted to employees of Cameco. Options granted under the stock option plan have an exercise price of not less than the closing price quoted on the Toronto Stock Exchange (TSX) for the common shares of Cameco on the trading day prior to the date on which the option is granted. The options carry vesting periods of one to three years, and expire eight years from the date granted.

The aggregate number of common shares that may be issued pursuant to the Cameco stock option plan shall not exceed 43,017,198 of which 32,196,059 shares have been issued.

Stock option transactions for the respective years were as follows:


(Number of options)	2023			2022
Beginning of year		3,053,571			3,458,001
Options granted		—			—
Options expired		—			(2,475	)
Options exercised [note 17]		(1,657,282	)		(401,955	)

End of year		1,396,289			3,053,571

Exercisable		1,396,289			3,053,571

Weighted average share prices were as follows:

Beginning of year	$	15.75	$	16.72
Options granted		—		—
Options expired		—		26.81
Options exercised		16.62		23.96

End of year	$	14.73	$	15.75

Exercisable	$	14.73	$	15.75

The weighted average share price at the dates of exercise during 2023 was $45.19 per share (2022 - $30.88).

Total options outstanding and exercisable at December 31, 2023 were as follows:


			Options outstanding				Options exercisable
Option price per share	Number		Weighted average remaining life		Weighted average exercisable price		Number		Weighted average exercisable price
$11.32 - 14.70		658,804		1.3	$	14.08		658,804	$	14.08
$14.71 - 16.38		737,485		3.0	$	15.32		737,485	$	15.32

		1,396,289						1,396,289

The foregoing options have expiry dates ranging from February 29, 2024 to February 28, 2027.

B. Executive performance share unit (PSU)

The Company has established a PSU plan whereby it provides each plan participant an annual grant of PSUs in an amount determined by the board. Each PSU represents one phantom common share that entitles the participant to a payment of one Cameco common share purchased on the open market, or cash with an equivalent market value, at the participant’s discretion provided they have met their ownership requirements, at the end of each three-year period if certain performance and vesting criteria have been met. The final value of the PSUs will be based on the value of Cameco common shares at the end of the three-year period and the number of PSUs that ultimately vest. During the vesting period, dividend equivalents accrue to the participants in the form of additional share units as of each normal cash dividend payment date of Cameco’s common shares. Vesting of PSUs at the end of the three-year period is based on Cameco’s ability to meet its annual operating targets and whether the participating executive remains employed by Cameco at the end of the three-year vesting period. If the participant elects a cash payout, the redemption amount will be based on the volume-weighted average trading price of Cameco’s common shares on March 1 or, if March 1 is not a trading day, on the first trading day following March 1. As of December 31, 2023, the total number of PSUs held by the participants, after adjusting for forfeitures on retirement, was 830,279 (2022 - 1,255,255).

C. Restricted share unit (RSU)

The Company has established an RSU plan whereby it provides each plan participant an annual grant of RSUs in an amount determined by the board. Each RSU represents one phantom common share that entitles the participant to a payment of one Cameco common share purchased on the open market, or cash with an equivalent market value, at the board’s discretion. The RSUs carry vesting periods of one to three years, and the final value of the units will be based on the value of Cameco common shares at the end of the vesting periods. In addition, certain eligible participants have a single vesting date on the third anniversary of the date of the grant. These same participants, if they have met or are not subject to share ownership requirements, may elect to have their award paid as a lump sum cash amount. During the vesting period, dividend equivalents accrue to the participants in the form of additional share units as of each normal cash dividend payment date of Cameco’s common shares. As of December 31, 2023, the total number of RSUs held by the participants was 814,683 (2022 - 1,131,493).

D. Phantom stock option

The Company has established a phantom stock option plan for eligible non-North American employees. Employees receive the equivalent value of shares in cash when exercised. Options granted under the phantom stock option plan have an award value equal to the closing price quoted on the TSX for the common shares of Cameco on the trading day prior to the date on which the option is granted. The options vest over three years and expire eight years from the date granted. As of December 31, 2023, the number of options held by participating employees was 45,551 (2022 - 94,135) with exercise prices ranging from $11.61 to $15.27 per share (2022 - $11.32 to $19.30) and a weighted average exercise price of $12.29 (2022 - $12.55).

E. Phantom restricted share unit (PRSU)

The Company has established a PRSU plan whereby it provides non-North American employees an annual grant of PRSUs in an amount determined by the board. Each PRSU represents one phantom common share that entitles the participant to a payment of cash with an equivalent market value. The PRSUs carry vesting periods of one to three years, and the final value of the units will be based on the value of Cameco common shares at the end of the vesting periods. In addition, certain eligible participants have a single vesting date on the third anniversary of the date of the grant. During the vesting period, dividend equivalents accrue to the participants in the form of additional share units as of each normal cash dividend payment date of Cameco’s common shares. As of December 31, 2023, the total number of PRSUs held by the participants was 28,000 (2022 - 21,148).

F. Employee share ownership plan

Cameco also has an employee share ownership plan, whereby both employee and Company contributions are used to purchase shares on the open market for employees. The Company’s contributions are expensed during the year of contribution. Under the plan, employees have the opportunity to participate in the program to a maximum of 6% of eligible earnings each year with Cameco matching the first 3% of employee-paid shares by 50%. Cameco contributes $1,000 of shares annually to each employee that is enrolled in the plan. Shares purchased with Company contributions and with dividends paid on such shares become unrestricted 12 months from the date on which such shares were purchased. At December 31, 2023, there were 2,838 participants in the plan (2022 - 2,603). The total number of shares purchased in 2023 with Company contributions was 100,379 (2022 - 116,530). In 2023, the Company’s contributions totaled $4,460,000 (2022 - $3,541,000).

G. Deferred share unit (DSU)

Cameco offers a DSU plan to non-employee directors. A DSU is a notional unit that reflects the market value of a single common share of Cameco. 60% of each director’s annual retainer is paid in DSUs. In addition, on an annual basis, directors can elect to receive 25%, 50%, 75% or 100% of the remaining 40% of their annual retainer and any additional fees in the form of DSUs. If a director meets their ownership requirements, the director may elect to take 25%, 50%, 75% or 100% of their annual retainer and any fees in cash, with the balance, if any, to be paid in DSUs. Each DSU fully vests upon award. Dividend equivalents accrue to the participants in the form of additional share units as of each normal cash dividend payment date of Cameco’s common shares. The DSUs will be redeemed for cash upon a director leaving the board. The redemption amount will be based upon the weighted average of the closing prices of the common shares of Cameco on the TSX for the last 20 trading days prior to the redemption date multiplied by the number of DSUs held by the director. As of December 31, 2023, the total number of DSUs held by participating directors was 564,401 (2022 - 547,304).

Equity-settled plans

Cameco records compensation expense under its equity-settled plans with an offsetting credit to contributed surplus, to reflect the estimated fair value of units granted to employees. During the year, the Company recognized the following expenses under these plans:


	2023		2022
Employee share ownership plan	$	4,460	$	3,541
Restricted share unit plan		3,692		3,273
Stock option plan		—		45

Total	$	8,152	$	6,859

Fair value measurement of equity-settled plans

The fair value of RSUs granted was determined based on their intrinsic value on the date of grant. Expected volatility was estimated by considering historic average share price volatility.

The inputs used in the measurement of the fair values at grant date of the equity-settled RSU plan were as follows:


	Grant date

Phantom stock option plan		1,908		751
Phantom restricted share unit plan		812		244

Total	$	59,225	$	24,369

At December 31, 2023, a liability of $79,771,000 (2022 - $59,577,000) was included in the consolidated statement of financial position to recognize accrued but unpaid expenses for cash-settled plans.

Fair value measurement of cash-settled plans

The fair value of the units granted through the PSU plan was determined based on Monte Carlo simulation and projections of the non-market criteria. The fair value of RSUs and PRSUs granted was determined based on their intrinsic value on the date of grant. The phantom stock option plan was measured based on the Black-Scholes option-pricing model. Expected volatility is estimated by considering historic average share price volatility.

The inputs used in the measurement of the fair values of the cash-settled share-based payment plans at the March 1, 2023 grant date were as follows:


							Phantom
	PSU			RSU			RSU
Number of units		232,160			162,930			9,997

Weighted average measurement date fair values	$	46.08		$	57.13		$	57.13		$	57.13

In addition to these inputs, other features of the PSU grant were incorporated into the measurement of fair value. The non-market criteria relating to realized selling prices and operating targets have been incorporated into the valuation at both grant and reporting date by reviewing prior history and corporate budgets.

26. Pension and other post-retirement benefits

Cameco maintains both defined benefit and defined contribution plans providing pension benefits to substantially all of its employees. All regular and temporary employees participate in a registered defined contribution plan. This plan is registered under the Pension Benefits Standard Act, 1985. In addition, all Canadian-based executives participate in a non-registered supplemental executive pension plan which is a defined benefit plan.

Under the supplemental executive pension plan (SEPP), Cameco provides a lump sum benefit equal to the present value of a lifetime pension benefit based on the executive’s length of service and final average earnings. The plan provides for unreduced benefits to be paid at the normal retirement age of 65, however unreduced benefits could be paid if the executive was at least 60 years of age and had 20 years of service at retirement. This program provides for a benefit determined by a formula based on earnings and service, reduced by the benefits payable under the registered base plan. Security is provided for the SEPP benefits through a letter of credit held by the plan’s trustee. The face amount of the letter of credit is determined each year based on the wind-up liabilities of the supplemental plan, less any plan assets currently held with the trustee. A valuation is required annually to determine the letter of credit amount. Benefits will continue to be paid from plan assets until the fund is exhausted, at which time Cameco will begin paying benefits from corporate assets.

Cameco also maintains non-pension post-retirement plans (“other benefit plans”) which are defined benefit plans that cover such benefits as group life insurance and supplemental health and dental coverage to eligible employees and their dependents. The costs related to these plans are charged to earnings in the period during which the employment services are rendered. These plans are funded by Cameco as benefit claims are made.

The board of directors of Cameco has final responsibility and accountability for the Cameco retirement programs. The board is ultimately responsible for managing the programs to comply with applicable legislation, providing oversight over the general functions and setting certain policies.

Cameco expects to pay $2,174,000 in contributions and letter of credit fees to its defined benefit plans in 2024.

The post-retirement plans expose Cameco to actuarial risks, such as longevity risk, market risk, interest rate risk, liquidity risk and foreign currency risk. The other benefit plans expose Cameco to risks of higher supplemental health and dental utilization than expected. However, the other benefit plans have limits on Cameco’s annual benefits payable.

The effective date of the most recent valuation for funding purposes on the registered defined benefit pension plans is January 1, 2021. The next planned effective date for valuations is January 1, 2024.

Cameco has more than one defined benefit plan and has generally provided aggregated disclosures in respect of these plans, on the basis that these plans are not exposed to materially different risks. Information relating to Cameco’s defined benefit plans is shown in the following table:


	Pension benefit plans						Other benefit plans

The percentages of the total fair value of assets in the pension plans for each asset category at December 31 were as follows:


	Pension benefit plans
	2023			2022
Asset category^(a)
Canadian equity securities		7	%		6	%
U.S. equity securities		12	%		11	%

Other^(b)		44	%		49	%

Total		100	%		100	%

(a)	The defined benefit plan assets contain no material amounts of related party assets at December 31, 2023 and 2022 respectively.

(b)	Relates mainly to the value of the refundable tax account held by the Canada Revenue Agency. The refundable total is approximately equal to half of the sum of the realized investment income plus employer contributions less half of the benefits paid by the plan.

The following represents the components of net pension and other benefit expense included primarily as part of administration.


	Pension benefit plans				Other benefit plans

Net pension and other benefit expense	$	22,540	$	19,204	$	1,676	$	1,641

The total amount of actuarial losses (gains) recognized in other comprehensive income is:


	Pension benefit plans						Other benefit plans
	2023			2022			2023		2022
Actuarial loss (gains)	$	6,343		$	(19,517	)	$	461	$	(5,720	)
Return on plan assets excluding interest income		(18	)		555			—		—

	$	6,325		$	(18,962	)	$	461	$	(5,720	)

The assumptions used to determine the Company’s defined benefit obligation and net pension and other benefit expense were as follows at December 31 (expressed as weighted averages):


	Pension benefit plans						Other benefit plans
	2023			2022			2023			2022
Discount rate - obligation		3.8	%		4.5	%		4.6	%		5.1	%
Discount rate - expense		4.5	%		2.3	%		5.1	%		2.9	%
Rate of compensation increase		2.9	%		3.0	%		—			—
Health care cost trend rate		—			—			5.0	%		5.0	%
Dental care cost trend rate		—			—			4.5	%		4.5	%

At December 31, 2023, the weighted average duration of the defined benefit obligation for the pension plans was 17.9 years (2022 - 17.1 years) and for the other benefit plans was 11.4 years (2022 - 11.3 years).

A 1% change at the reporting date to one of the relevant actuarial assumptions, holding other assumptions constant, would have affected the defined benefit obligation by the following:


	Pension benefit plans					Other benefit plans
	Increase			Decrease		Increase			Decrease
Discount rate	$	(7,739	)	$	9,817	$	(2,143	)	$	2,628

A 1% change in any of the other assumptions would not have a significant impact on the defined benefit obligation.

The methods and assumptions used in preparing the sensitivity analyses are the same as the methods and assumptions used in determining the financial position of Cameco’s plans as at December 31, 2023. The sensitivity analyses are determined by varying the sensitivity assumption and leaving all other assumptions unchanged. Therefore, the sensitivity analyses do not recognize any interdependence in the assumptions. The methods and assumptions used in determining the above sensitivity are consistent with the methods and assumptions used in the previous year.

In addition, an increase of one year in the expected lifetime of plan participants in the pension benefit plans would increase the defined benefit obligation by $1,583,000.

To measure the longevity risk for these plans, the mortality rates were reduced such that the average life expectancy for all members increased by one year. The reduced mortality rates were subsequently used to re-measure the defined benefit obligation of the entire plan.

27. Financial instruments and related risk management

Cameco is exposed in varying degrees to a variety of risks from its use of financial instruments. Management and the board of directors, both separately and together, discuss the principal risks of our businesses. The board sets policies for the implementation of systems to manage, monitor and mitigate identifiable risks. Cameco’s risk management objective in relation to these instruments is to protect and minimize volatility in cash flow. The types of risks Cameco is exposed to, the source of risk exposure and how each is managed is outlined below.

Market risk

Market risk is the risk that changes in market prices, such as commodity prices, foreign currency exchange rates and interest rates, will affect the Company’s earnings or the fair value of its financial instruments. Cameco engages in various business activities which expose the Company to market risk. As part of its overall risk management strategy, Cameco uses derivatives to manage some of its exposures to market risk that result from these activities.

Derivative instruments may include financial and physical forward contracts. Such contracts may be used to establish a fixed price for a commodity, an interest-bearing obligation or a cash flow denominated in a foreign currency. Market risks are monitored regularly against defined risk limits and tolerances.

Cameco’s actual exposure to these market risks is constantly changing as the Company’s portfolios of foreign currency and interest rate contracts change.

The types of market risk exposure and the way in which such exposure is managed are as follows:

A. Commodity price risk

As a significant producer and supplier of uranium and nuclear fuel processing services, Cameco bears significant exposure to changes in prices for these products. A substantial change in prices will affect the Company’s net earnings and operating cash flows. Prices for Cameco’s products are volatile and are influenced by numerous factors beyond the Company’s control, such as supply and demand fundamentals and geopolitical events.

Cameco’s sales contracting strategy focuses on reducing the volatility in future earnings and cash flow, while providing both protection against decreases in market price and retention of exposure to future market price increases. To mitigate the risks associated with the fluctuations in the market price for uranium products, Cameco seeks to maintain a portfolio of uranium product sales contracts with a variety of delivery dates and pricing mechanisms that provide a degree of protection from pricing volatility.

B. Foreign exchange risk

The relationship between the Canadian and US dollar affects financial results of the uranium business as well as the fuel services business. Sales of uranium product, conversion and fuel manufacturing services are routinely denominated in US dollars while production costs are largely denominated in Canadian dollars.

Cameco attempts to provide some protection against exchange rate fluctuations by planned hedging activity designed to smooth volatility. To mitigate risks associated with foreign currency, Cameco enters into forward sales and option contracts to establish a price for future delivery of the foreign currency. These foreign currency contracts are not designated as hedges and are recorded at fair value with changes in fair value recognized in earnings. Cameco also has a natural hedge against US currency fluctuations because a portion of its annual cash outlays, including purchases of uranium and conversion services, is denominated in US dollars.

Cameco holds a number of financial instruments denominated in foreign currencies that expose the Company to foreign exchange risk. Cameco measures its exposure to foreign exchange risk on financial instruments as the change in carrying values that would occur as a result of reasonably possible changes in foreign exchange rates, holding all other variables constant. As of the reporting date, the Company has determined its pre-tax exposure to foreign currency exchange risk on financial instruments to be as follows based on a 5% weakening of the Canadian dollar:


			Carrying value
	Currency		(Cdn)			Gain (loss)
Cash and cash equivalents		USD	$	144,149		$	7,207
Accounts receivable		USD		371,618			18,581
Accounts payable and accrued liabilities		USD		(302,364	)		(15,118	)
Long-term debt		USD		(786,397	)		(39,320	)
Net foreign currency derivatives		USD		11,942			(102,567	)

C. Interest rate risk

The Company has a strategy of minimizing its exposure to interest rate risk by maintaining target levels of fixed and variable rate borrowings. The proportions of outstanding debt carrying fixed and variable interest rates are reviewed by senior management to ensure that these levels are within approved policy limits. At December 31, 2023, the proportion of Cameco’s outstanding debt that carries fixed interest rates is 51% (2022 - 92%).

Cameco was exposed to interest rate risk during the year through its interest rate swap contracts whereby fixed rate payments on a notional amount of $75,000,000 of the Series H senior unsecured debentures were swapped for variable rate payments. Under the terms of the swap, Cameco makes interest payments based on the three-month Canada Dealer Offered Rate plus an average margin of 1.3% and receives fixed interest payments of 2.95%. At December 31, 2023, the fair value of Cameco’s interest rate swap net liability was $5,819,000 (2022 - $7,284,000).

Cameco is also exposed to interest rate risk through its term loan which consists of two $300,000,000 (US) tranches. The first tranche has a floating interest rate of SOFR plus 1.80% and matures on November 7, 2025. The second tranche has a floating interest rate of SOFR plus 2.05% and matures on November 7, 2026.

Cameco measures its exposure to interest rate risk as the change in cash flows that would occur as a result of reasonably possible changes in interest rates, holding all other variables constant. As of the reporting date, the Company has determined the impact on earnings of a 1% increase in interest rate on its variable rate financial instruments to be as follows:


	Gain (loss)
Interest rate contracts	$	(760	)
Floating rate term loan		(7,946	)

Counterparty credit risk

Counterparty credit risk is associated with the ability of counterparties to satisfy their contractual obligations to Cameco, including both payment and performance. The maximum exposure to credit risk, as represented by the carrying amount of the financial assets, at December 31 was:


	2023		2022
Cash and cash equivalents	$	566,809	$	1,143,674
Short-term investments		—		1,138,174
Accounts receivable [note 7]		415,561		178,088
Derivative assets [note 11]		28,467		2,807

Cash and cash equivalents

Cameco held cash and cash equivalents of $566,809,000 at December 31, 2023 (2022 - $1,143,674,000). Cameco mitigates its credit risk by ensuring that balances are held with counterparties with high credit ratings. The Company monitors the credit rating of its counterparties on a monthly basis and has controls in place to ensure prescribed exposure limits with each counterparty are adhered to.

Impairment on cash and cash equivalents has been measured on a 12-month ECL basis and reflects the short maturities of the exposures. The Company considers that its cash and cash equivalents have low credit risk based on the external credit ratings of the counterparties. Cameco has assessed its counterparty credit risk on cash and cash equivalents by applying historic global default rates to outstanding cash balances based on S&P rating. The conclusion of this assessment is that the loss allowance is insignificant.

Short-term investments

Cameco held no short-term investments at December 31, 2023 (2022 - $1,138,174,000). The Company mitigates its credit risk by requiring that the issuer/guarantor of the investment have a minimum short-term credit rating and/or a long-term debt rating at the time of purchase, according to the investment credit ratings as issued by DBRS or S&P, or the equivalent of the DBRS or S&P rating at another reputable rating agency.

In addition to the credit-rating requirement, Cameco also mitigates risk by prescribing limits by counterparty and types of investment products.

Cameco has assessed its counterparty credit risk related to short-term investments by applying historic default rates to outstanding investment balances based on S&P rating. The conclusion of this assessment is that the loss allowance is insignificant.

Accounts receivable

Cameco’s sales of uranium product, conversion and fuel manufacturing services expose the Company to the risk of non-payment. Cameco manages the risk of non-payment by monitoring the credit-worthiness of its customers and seeking pre-payment or other forms of payment security from customers with an unacceptable level of credit risk.

A summary of the Company’s exposure to credit risk for trade receivables is as follows:


	Carrying value
Investment grade credit rating	$	290,204
Non-investment grade credit rating		123,588

Total gross carrying amount	$	413,792
Loss allowance		—

Net	$	413,792

At December 31, 2023, there were no significant concentrations of credit risk and no amounts were held as collateral. Historically, Cameco has experienced minimal customer defaults and, as a result, considers the credit quality of its accounts receivable to be high.

Cameco uses customer credit rating data, historic default rates and aged receivable analysis to measure the ECLs of trade receivables from corporate customers, which comprise a small number of large balances. Since the Company has not experienced customer defaults in the past, applying historic default rates in calculating ECLs, as well as considering forward-looking information, resulted in an insignificant allowance for losses.

The following table provides information about Cameco’s aged trade receivables as at December 31, 2023:


	Corporate customers		Other customers		Total
Current (not past due)	$	393,296	$	2,366		395,662
1-30 days past due		16,531		889		17,420
More than 30 days past due		131		579		710

Total	$	409,958	$	3,834		413,792

Liquidity risk

Financial liquidity represents Cameco’s ability to fund future operating activities and investments. Cameco ensures that there is sufficient capital in order to meet short-term business requirements, after taking into account cash flows from operations and the Company’s holdings of cash and cash equivalents. The Company believes that these sources will be sufficient to cover the likely short-term and long-term cash requirements.

The table below outlines the Company’s available debt facilities at December 31, 2023:


	Total amount		Outstanding and committed		Amount available
Unsecured revolving credit facility [note 14]	$	1,000,000	$	—	$	1,000,000
Letter of credit facilities [note 14]		1,771,663		1,383,689		387,974

The tables below present a maturity analysis of Cameco’s financial liabilities, including principal and interest, based on the expected cash flows from the reporting date to the contractual maturity date:

Cameco has pledged $156,274,000 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.

Cameco has issued guarantees to certain banks in respect of the credit facilities granted to various subsidiaries. These facilities consist of daily overdraft limits and credit lines. At December 31, 2023 the Company has issued guarantees of up to $278,006,000 ($209,927,000 (US)), which is the maximum amount the Company could be exposed to at any point in time.

Cameco has not irrevocably designated a financial asset that would otherwise meet the requirements to be measured at amortized cost at FVOCI or FVTPL to eliminate or significantly reduce an accounting mismatch that would otherwise arise.

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

Net	$	(1,052,535	)	$	(1,069,545	)

The preceding tables exclude fair value information for financial instruments whose carrying amounts are a reasonable approximation of fair value. The carrying values of Cameco’s cash and cash equivalents, short-term investments, accounts receivable, and accounts payable and accrued liabilities approximate their fair values 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 3 as of the reporting date.

B.	Financial instruments measured at fair value

Cameco measures its derivative financial instruments and long-term debt at fair value. Derivative financial instruments and long-term debt are classified as a recurring level 2 fair value measurement.

The fair value of Cameco’s long-term debt is determined using quoted market yields as of the reporting date, which ranged from 3.1% to 4.9% (2022 - 3.3% to 4.2%). The fair value of the floating rate term loan is equal to its carrying value.

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 Dealer Offer Rate 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.

Capital management

Cameco’s management considers its capital structure to consist of bank overdrafts, long-term debt, short-term debt (net of cash and cash equivalents and short-term investments), non-controlling interest and shareholders’ equity.

Cameco’s capital structure reflects its strategy and the environment in which it operates. Delivering returns to long-term shareholders is a top priority. The Company’s objective is to maximize cash flow while maintaining its investment grade rating through close capital management of our balance sheet metrics. Capital resources are managed to allow it to support achievement of its goals while managing financial risks such as weakness in the market, litigation risk and refinancing risk. The overall objectives for managing capital in 2023 reflect the environment that the Company is operating in, similar to the prior comparative period.

The capital structure at December 31 was as follows:


	2023			2022
Current portion of long-term debt [note 14]	$	499,821		$	—
Long-term debt [note 14]		1,284,353			997,000
Cash and cash equivalents		(566,809	)		(1,143,674	)
Short-term investments		—			(1,138,174	)

Shareholders’ equity		6,094,305			5,836,054

Total equity		6,094,309			5,836,065

Total capital	$	7,311,674		$	4,551,217

Cameco is bound by certain covenants in its general credit facilities. These covenants place restrictions on total debt, including guarantees and set minimum levels for net worth. As of December 31, 2023, Cameco met these requirements.

29.

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 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 12). 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 as well as operational readiness costs for our operations that have resumed operations. Operational readiness costs include costs to complete critical projects, perform maintenance readiness checks, and recruit and train sufficient mine and mill personnel before beginning operations. Cameco expensed $50,615,000 of care and maintenance costs during the year (2022 - $218,439,000 of care and maintenance and operational readiness costs).

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

Joint operations

Cameco conducts a portion of its exploration, development, mining and milling activities through joint operations. Operations are governed by agreements that provide for joint control of the strategic operating, investing and financing activities among the partners. These agreements were considered in the determination of joint control. Cameco’s significant Canadian uranium joint operation interests are McArthur River, Key Lake and Cigar Lake. The Canadian uranium joint operations allocate 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.

Cameco reflects its proportionate interest in these assets and liabilities as follows:


	Principal place of business		Ownership			2023		2022
Total assets
McArthur River		Canada		69.81	%	$	1,048,746	$	998,368

MANAGEMENT’S DISCUSSION AND ANALYSIS 9

Market overview and developments

A market in transition

In 2023, geopolitical uncertainty and heightened concerns about energy security and climate change continued to improve the demand and supply fundamentals for the nuclear power industry and the fuel cycle that is required to support it. Increasingly, countries and companies around the globe are recognizing the critical role nuclear power must play in providing clean and secure baseload power. This growing support has led to a rise in demand as reactors are being saved from earlier retirement, 10- and 20-year life extensions are being sought and approved for existing reactor fleets in several countries, and numerous commitments and plans are being made for the construction of new nuclear generating capacity. In addition, there is increasing interest in small modular reactors (SMR), including smaller versions of existing technology and advanced technology designs, which are expected to add to demand in the decades to come, with several projects already underway.

While demand continues to increase, future supply is not keeping pace. Heightened supply risk caused by growing geopolitical uncertainty, shrinking secondary supplies and a lack of investment in new capacity over the past decade has motivated utilities to evaluate their near-, mid- and long-term nuclear fuel supply chains. The uncertainty about where nuclear fuel supplies will come from to satisfy growing demand has led to increased long-term contracting activity and in 2023, about 160 million pounds of uranium was placed under long-term contracts by utilities. While it is the highest annual volume contracted since 2012, it remains below replacement rate and includes our contract with Ukraine, which alone accounted for about 30 million of those pounds. Prices across the nuclear fuel cycle continued to rise in 2023, with spot enrichment prices up 38%, conversion prices continuing to achieve record highs, uranium spot prices more than doubling from around $48 (US) per pound at the end of 2022 to $100 (US) per pound at the end of January 2024, after peaking at $106 (US) per pound earlier in the month, and the long-term price for uranium increasing about 38% over the same period. We expect there will be continued competition to secure uranium, conversion services and enrichment services under long-term contracts with proven producers and suppliers who have a diversified portfolio of assets in geopolitically attractive jurisdictions, with strong environmental, social and governance (ESG) performance, and on terms that help ensure a reliable supply is available to satisfy demand.

DURABLE DEMAND GROWTH

The benefits of nuclear energy have come clearly into focus, supporting a level of durability that, we believe, has not been previously seen. The durability is being driven not only by accountability for achieving the net-zero carbon targets set by countries and companies around the world, but also by a geopolitical realignment in energy markets that is causing countries to reexamine how they plan to address their energy needs. Net-zero carbon targets are turning global attention to a triple challenge. First, about one-third of the global population must be lifted out of energy poverty by improving access to clean and reliable baseload electricity. Second, approximately 80% of the current global electricity grids that run on carbon-emitting sources of thermal power must be replaced with a clean, reliable alternative. And finally, global power grids must grow by electrifying industries, such as private and commercial transportation, and home and industrial heating, which today are largely powered with carbon-emitting sources of thermal energy. Additionally, geopolitical uncertainty has deepened concerns about energy security, highlighting the role of energy policy in balancing three main objectives: providing a clean emissions profile; providing a reliable and secure baseload profile; and providing an affordable, levelized cost profile. There is increasing recognition that nuclear power meets these objectives and has a key role to play in achieving decarbonization and energy security goals. The growth in demand is not just long-term and in the form of new builds, but medium-term in the form of reactor life extensions, and near-term with early reactor retirement plans being deferred or cancelled and new markets continuing to emerge. And, we are seeing even more long-term momentum building with the development of SMRs, where the use case extends beyond just power generation and numerous companies and countries are pursuing projects.

Demand and energy policy highlights

•

In September, the World Nuclear Association released its biennial Global Nuclear Fuel Report which provides scenarios for demand and supply availability across the fuel supply chain through 2040. This included a robust demand outlook showing global nuclear generating capacity increasing to 686 GWe by 2040 in the Reference Scenario, an average annual growth rate of 3.6%, compared to 2.6% in the 2021 report. This improvement was driven by improved government support, life extensions, new builds and importantly, that starting in the 2030s, the deployment of SMRs is forecasted to contribute to capacity growth. Additional key themes include assumed reductions to secondary supply and decreased availability of mobile inventories, along with the need for a growing volume of future uranium supply requiring higher incentive pricing to balance the market after 2030.

•

At the 28th annual Conference of Parties (COP28), the 2023 United Nations Climate Change Conference held in the United Arab Emirates, 22 countries (now 28) launched a declaration to triple nuclear energy capacity by 2050. For the first time at the conference, nuclear energy was recognized alongside other low-emissions technologies for the key role it must play in reaching global net-zero greenhouse gas emissions by 2050. In addition, the inaugural global stocktake was introduced at COP28, a process where countries and stakeholders can provide an update every five years to track the world’s progress toward the Paris Agreement targets. In 2023, the initiative concluded that more action is required, as emissions continue to rise and put 2030 targets at risk, reinforcing that in order to achieve net zero by 2050, the world needs “absolute economy-wide emission reduction targets”, which were estimated at a cost of “trillions of dollars”.

•

China Nuclear Energy Association published the “China Nuclear Energy Development Report 2023” in April, which highlighted China’s continuing growth. According to the report, the country is expected to lead the world in installed nuclear capacity with 110 GWe expected by 2030, rising to 150 GWe expected by 2035, and plans to build over 90% of their major nuclear power reactors domestically. Additionally, a proposal drafted by 15 Chinese national policy advisors was submitted to the government advocating for the development of new nuclear power plants at inland sites, which are now being considered following the end of a post-Fukushima moratorium on proposed inland nuclear power plants.

•

In Japan, Takahama unit 2 restarted in September, becoming the country’s 12th reactor to restart since Fukushima. Onagawa unit 2 and Shimane unit 2 are expected to restart in 2024. In November, the Nuclear Regulation Authority approved 20-year life extensions (beyond 40 years) for Sendai units 1 and 2; additionally, Takahama units 3 and 4 are expected to receive similar life extensions, pending generator work in 2026 and 2027. In addition, Japan enacted a bill in May allowing nuclear reactors to operate beyond the 60-year limit.

•

In South Korea, Korea Hydro and Nuclear Power (KHNP) announced in September that they successfully completed fuel loading at Shin Hanul unit 2, a new 1,400 MWe APR-1400 pressurized water reactor (PWR) unit. This followed an announcement from the Ministry of Industry and Energy that Shin Hanul units 3 and 4 would be completed by the end of 2024. Additionally, to help achieve the plans set out in their 10th Basic Plan for Electricity Supply and Demand 2030, which targets more than 30% of its power supply to come from nuclear, the Ministry confirmed a review of the need for new nuclear power plants was underway.

•

In India, the first domestically designed 700 MWe pressurized heavy water reactor, Kakrapar unit 3, reached full operating capacity in August. Three more units of the same design are expected to come online in the next few years. The country is targeting an expansion of nuclear generating capacity to 22.5 GWe by 2031.

•

In February, the European Nuclear Alliance was launched. Led by France, the initiative commits 11 European countries to cooperate across the nuclear fuel supply chain, and to promote new nuclear generation projects and technologies, including the advancement of SMRs. Throughout 2023, the alliance expanded and now includes a commitment from 16 European countries that will prepare a roadmap to develop an integrated European nuclear industry and target 150 GWe of nuclear power by 2050.

•

In France, plans were advanced to relaunch the country’s reactor construction program: the government committed to life extensions with a proposed “industrial build” program that initially includes six new European Pressurized Reactors (EPR), as well as eight additional EPRs in the future. Électricité de France filed an application to build the first pair of 1,650 MWe EPRs with construction scheduled to begin in 2028.

•

In January 2024, the United Kingdom (UK) announced that they are seeking to quadruple their nuclear power output by 2050. Under the “Civil Nuclear Roadmap”, the UK will invest into developing new advanced nuclear fuel, new regulations, and a new nuclear reactor.

MANAGEMENT’S DISCUSSION AND ANALYSIS 11

•

In June, Sweden’s parliament adopted a new energy target, changing its focus to “100% fossil-free” electricity as opposed to the previously stated focus of “100% renewable”. In August, the government announced a target to further expand the role of nuclear power and in November, announced its intention to build up to 2,500 MWe of new nuclear power capacity by 2035, and up to 10 new reactors by 2045, backed by an offer of loan guarantees.

•

In Belgium, the government and nuclear operator ENGIE reached an agreement following prolonged negotiations to extend the lifespans of the Doel unit 4 and Tihange unit 3 reactors by 10 years, with each now expected to operate until 2035.

•

In Bulgaria, the government issued its 30-year energy strategy to 2053, which envisions the construction of four new nuclear reactor units. In December, parliament approved a government proposal to inject up to 1.5 billion levs ($838 million (US)) into the state-owned Kozloduy Nuclear Power Plant to fund the planned construction of the first of two proposed reactors using Westinghouse’s AP1000^® technology.

•

In Poland, the government adopted a resolution committing to finance the country’s first nuclear power plant. The funds will go to Polish utility Polskie Elektrownie Jadrowe, which signed a contract with Westinghouse for multiple AP1000 reactors in February of 2023.

•

In the US, Vogtle unit 3 entered commercial service on July 31, after becoming the first Westinghouse AP1000 reactor in the US to successfully connect to the electrical grid. Vogtle unit 4 is expected to begin operating in the second quarter of 2024.

•

Throughout 2023, many US states expressed local support for nuclear: Ohio, Virginia, Kentucky, and Tennessee all began creating state-level advisory authorities to promote, research and develop nuclear power technologies, and Michigan formed a new Nuclear Caucus to support the reopening of the Palisades nuclear power plant, and also approved extending operations at the Monticello nuclear power plant through 2040.

•

In Canada, provincial support for nuclear increased in 2023. New Brunswick Power signed a three-year contract with Ontario Power Generation (OPG) to enhance the operational performance of the Point Lepreau nuclear power plant. In Ontario, the Minister of Energy announced support to advance the long-term planning required to explore nuclear expansion options for Bruce Power, outlining the need for nearly 18 GWe in new nuclear capacity to help the province reach its electrification and net-zero goals. Additionally, in Saskatchewan, Crown Investments Corporation provided around $479,000 to help local firms build small, advanced, and micro reactors supply chain capacity, while the Alberta government announced plans to invest around $7 million to study SMRs.

•

In January 2024, OPG announced plans to proceed with the refurbishment of the Pickering Nuclear Generating Station’s “B” units (units 5, 6, 7 and 8). Once the project is completed in the mid-2030s, Pickering would produce a total of 2 GWe of electricity, to help meet increasing electricity demand and fuel the province’s economic growth.

According to the International Atomic Energy Agency (IAEA), globally there are currently 438 operable reactors and 58 reactors under construction. Several nations are appreciating the clean energy and energy security benefits of nuclear power and have reaffirmed their commitment with plans underway to support existing reactor units and review policies to encourage more nuclear generation. Several other non-nuclear countries have emerged as candidates for new nuclear capacity. In the EU, specific nuclear energy projects have been identified for inclusion under its sustainable financing taxonomy and are therefore eligible for access to low-cost financing. In Canada, the government revised the Canada Green Bond Framework to include nuclear energy projects. In some countries where phase-out policies have been in place, policy reversals and decisions have been made to temporarily keep reactors running, with public opinion polls showing increasing support. With a number of reactor construction projects recently approved and many more planned, demand for uranium continues to improve. There is growing recognition of the role nuclear must play in providing safe, affordable, carbon-free baseload electricity to achieve a low-carbon economy, while being a reliable energy source that helps countries move away from Russian energy supply.

SUPPLY UNCERTAINTY

Geopolitical uncertainty remained the most notable factor impacting security of supply in 2023. Driven by the Russian invasion of Ukraine, and more recently, the coup d’état in Niger, many governments and utilities are re-examining supply chains and procurement strategies that rely on nuclear fuel supplies from these jurisdictions. In addition, sanctions on Russia and Niger, government restrictions, and restrictions on and cancellations of some cargo insurance coverages continue to create transportation and supply chain risks for nuclear fuel supplies coming out of Central Asia. There are also transportation risks to material being shipped from Australia to Europe as a result of the conflict in the Middle East. Despite the recent increase in market prices, the deepening geopolitical uncertainty and years of underinvestment in new uranium and fuel cycle service capacities has shifted risk from producers to utilities.

Supply and trade policy highlights

•

Sprott Physical Uranium Trust (SPUT) purchased about 4 million pounds U₃O₈ in 2023, bringing total purchases since inception to over 45 million pounds U₃O₈ and increasing the total net asset value to around $7 billion (US). Volatility in equity markets has impacted SPUT’s valuation (discount or premium to its net asset value) and therefore its ability to raise funds to purchase uranium.

•

In June, Kazatomprom (KAP) announced plans to start production at a new uranium deposit, Inkai 3 (100% owned by KAP). KAP expects approval of a Subsoil Use Agreement (SSUA) to produce 10.4 million pounds U₃O₈ annually for 25 years from Inkai 3’s uranium resources of about 216 million pounds U₃O₈.

MANAGEMENT’S DISCUSSION AND ANALYSIS 13

•

In September, KAP had restated its plan to increase production in 2024 to 90% of SSUAs and announced a ramp up to 100% of SSUAs in 2025, though the company also warned that geopolitical uncertainty, global supply chain issues, and inflationary pressure could create challenges. On January 12, 2024, KAP announced that it had faced challenges in completing the development required to achieve the planned 2024 production increase, and that it expected to lower its 2024 uranium production guidance due to limited availability of sulfuric acid and delays in the construction and development of new assets, including Budenovskoye 6 and 7. On February 1, 2024, KAP rescinded its 2024 target due to the shortage of sulfuric acid and construction delays in 2023, and they now plan to remain about 20% below SSUAs, expecting to produce between 55 million and 59 million pounds U₃O₈ in 2024 (previously 65 million to 66 million pounds U₃O₈). KAP also warned that if the acid, supply chain and construction issues persist throughout 2024, the company’s 2025 plan to increase production to 100% of SSUAs (79 million to 82 million pounds U₃O₈) may also be affected.

•

In April, five of the G7 countries (Canada, France, Japan, UK, and US), entered into a civil nuclear fuel security agreement that attempts to reduce Russia’s influence in the global nuclear fuel supply chain.

•

In December, Urenco announced its decision to expand enrichment capacity at their facility in Almelo, Netherlands, increasing capacity by 15% or approximately 750,000 separative work units (SWU), by 2027. This followed a prior announcement of plans to expand enrichment capacity at its Urenco USA site, increasing capacity there by 15% or approximately 700,000 SWU, by 2025.

•

In October, Orano announced a planned enrichment capacity extension project at Georges Besse 2. The project, forecasted to cost €1.7 billion, seeks to increase capacity by over 30% or approximately 2.5 million SWU, beginning in 2028.

•

In July, ConverDyn announced the restart of Honeywell’s Metropolis uranium conversion facility. The restart plan had been delayed by a safety equipment failure in June, resulting in a special inspection by the US Nuclear Regulatory Commission. The facility restarted production in July 2023.

•

In July, a coup d’état in Niger resulted in a group of military officers removing President Mohamed Bazoum and seizing power. All exports of uranium and gold to France were suspended and in September, Orano stated that it had halted uranium processing operations at the company’s majority-owned SOMAIR (Arlit) project in Niger due to logistical complications caused by international sanctions. This resulted in 2023 production dropping to 3.9 million pounds U₃O₈, compared to around 5.2 million pounds U₃O₈ in 2022.

•

In December, the US House of Representatives passed the Prohibiting Russian Uranium Impacts Act. The act proposes to prohibit the import of Russian low-enriched uranium (LEU) into the US, but includes waivers that allow the import of LEU from Russia if the US Energy Secretary determines no alternative source can be procured, or if the shipments are of national interest. The waivers would gradually reduce and eliminate Russian uranium imports by 2028. The bill is awaiting further action after it was blocked by the US Senate on grounds unrelated to the bill itself. Separately, the US Senate Energy and Natural Resources Committee passed the Nuclear Fuel Security Act of 2023, which directs the Department of Energy to create a “Nuclear Fuel Security Program” and strengthen the US nuclear fuel supply chain, including new LEU and high-assay low-enriched uranium (HALEU) capacity, though no new funding has yet been appropriated. Finally, a Supplemental Funding Bill is progressing through Congress and includes roughly $111 billion (US) for national security measures, including a provision for $2.72 billion (US) to be allocated to a new “American Energy Independence Fund”, which would acquire non-Russian LEU and HALEU, subject to the ban on Russian imports becoming law.

Long-term contracting creates full-cycle value for proven productive assets

Like other commodities, the demand for uranium is cyclical. However, unlike other commodities, uranium is not traded in meaningful quantities on a commodity exchange. The uranium market is principally based on bilaterally negotiated long-term contracts covering the annual run-rate requirements of nuclear power plants, with a small spot market to serve discretionary demand. History demonstrates that in general, when prices are rising and high, uranium is perceived as scarce, and more contracting activity takes place with proven and reliable suppliers. The higher demand discovered during this contracting cycle drives investment in higher-cost sources of production, which due to lengthy development timelines, tend to miss the contracting cycle and ramp up after demand has already been won by proven producers. When prices are declining and low, there is no perceived urgency to contract, and contracting activity and investment in new supply dramatically decreases. After years of low prices, and a lack of investment in supply, and as the uncommitted material available in the spot market begins to thin, security-of-supply tends to overtake price concerns. Utilities typically re-enter the long-term contracting market to ensure they have a reliable future supply of uranium to run their reactors.

UxC reports that over the last five years approximately 510 million pounds U₃O₈ equivalent have been locked-up in the long-term market, while approximately 780 million pounds U₃O₈ equivalent have been consumed in reactors. We remain confident that utilities have a growing gap to fill.

We believe the current backlog of long-term contracting presents a substantial opportunity for proven and reliable suppliers with tier-one productive capacity and a record of honoring supply commitments. As a low-cost producer, we manage our operations to increase value throughout these price cycles.

LOGO

In our industry, customers do not come to the market right before they need to load nuclear fuel into their reactors. To operate a reactor that could run for more than 60 years, natural uranium and the downstream services have to be purchased years in advance, allowing time for a number of processing steps before a finished fuel bundle arrives at the power plant. At present, we believe there is a significant amount of uranium that needs to be contracted to keep reactors running into the next decade.

UxC estimates that cumulative uncovered requirements are about 2.2 billion pounds to the end of 2040. With the lack of investment over the past decade, there is growing uncertainty about where uranium will come from to satisfy growing demand, and utilities are becoming increasingly concerned about the availability of material to meet their long-term needs. In addition, secondary supplies have diminished, and the material available in the spot market has thinned as producers and financial funds continue to purchase material. Furthermore, geopolitical uncertainty is causing some utilities to seek nuclear fuel suppliers whose values are aligned with their own or whose origin of supply better protects them from potential interruptions, including from transportation challenges or the possible imposition of formal sanctions.

MANAGEMENT’S DISCUSSION AND ANALYSIS 15

We will continue to take the actions we believe are necessary to position the company for long-term success. Therefore, we will continue to align our production decisions with our customers’ needs under our contract portfolio. We will undertake contracting activity which is intended to ensure we have adequate protection while maintaining exposure to the benefits that come from having uncommitted, low-cost supply to place into a strengthening market.

2023 performance highlights

It was another positive year for the nuclear energy industry. Demand for nuclear power, including support for existing reactors, continues to grow, catalyzed by the increasing recognition by policy makers and major industries that nuclear energy must play an important role in achieving the objectives of providing clean, secure, reliable and affordable energy. We recently announced our commitment to the Net Zero Nuclear initiative, which is calling for collaboration among government, industry leaders and civil society to triple global nuclear capacity to achieve carbon neutrality by 2050. We believe nuclear energy is back in durable growth mode, and we too are back in durable growth mode. This growth will be sought in the same manner as we approach all aspects of our business; strategic, deliberate, disciplined and responsible and with a focus on generating full-cycle value.

In our uranium segment, our portfolio of long-term contracts totals approximately 205 million pounds representing only about 20% of our current reserve and resource base, providing us with plenty of exposure to improving demand from our customers as they look to secure their long-term needs. We continue to have a large and growing pipeline of uranium business under discussion. Our focus continues to be on obtaining market-related pricing mechanisms, while also providing adequate downside protection. We continue to be strategically patient in our discussions to maximize value in our contract portfolio and to maintain exposure to higher prices with unencumbered future productive capacity. In addition, with strong demand in the UF₆ conversion market, we were successful in adding new long-term contracts that bring our total contracted volumes to over 75 million kgU of UF₆ that will underpin that operation for years to come.

At McArthur River/Key Lake, we produced 13.5 million pounds (100% basis) of packaged uranium concentrate (14.8 million pounds at the mine, 13.5 million pounds of which were packaged at the mill), slightly below our most recent estimate of 14 million pounds (100% basis). At Cigar Lake, we produced 15.1 million pounds (100% basis) of packaged uranium, which is in line with our most recent estimate of up to 16.3 million pounds (100% basis). Any pounds we did not produce in 2023 remain available to us and, with increasing supply pressures, have potentially become more valuable when delivered in the future.

Through our investment in Inkai, we were impacted by the 20% supply reduction enacted by Kazatomprom (KAP) across all uranium mines in Kazakhstan and the continued supply chain challenges it has faced. As well, delivery of our share of 2023 production from JV Inkai was delayed due to the challenges of transporting uranium via an alternate route that does not rely on Russian rail lines or ports. The first shipment, containing approximately two thirds of our share of Inkai’s 2023 production, arrived in the fourth quarter. The second shipment with the remainder of our share of 2023 production has arrived at a Canadian port.

Cameco has 35 years of experience in this market, and we have designed our strategy of full-cycle value capture to be resilient. Given the nature of our contracts, we have good visibility into when and where we need to deliver material, and we have put in place a number of tools that allow us to self-manage risk.

We have built a strong reputation as a proven and reliable supplier with a diversified production portfolio, that provides us with the flexibility to work with our customers to ensure they maintain access to our reliable supplies to satisfy their ongoing fuel requirements. In addition to our production, we can source material from market purchases today, and while these purchases would be more expensive than our production, our strategy positions us to benefit from added demand for nuclear fuel supplies and services. We have exposure to higher prices under the market-related contracts in our long-term portfolio and a pipeline of contracting discussions underway, which we expect will also benefit from the increased focus on securing access to scarce supplies and generate long-term value for Cameco. Also, we do not have to buy every pound in the spot market. We can source from inventory, to be replaced by production or purchases later. Further, we have the ability to pull forward long-term purchase arrangements that we put in place in a much lower-price environment, and with licensed storage facilities, we have secured the ability to borrow product under the terms of some of our storage agreements.

Global production shortfalls and transportation challenges in 2023 further highlighted the growing security of supply risk at a time when we believe the demand outlook is stronger and more durable than ever, with 28 countries around the world committing to triple nuclear power capacity by 2050. In this environment, uncertainty about where nuclear fuel supplies will come from to satisfy growing demand continues to drive long-term contracting as risk shifts from producers to utilities.

We delivered 32 million pounds of uranium and 12 million kgU in our fuel services segment to our customers in alignment with our contract portfolio and profitable opportunities in the market. We generated $688 million in cash from operations, with

MANAGEMENT’S DISCUSSION AND ANALYSIS 17

higher sales volumes and higher average realized prices in both our uranium and fuel services segments than in 2022. To meet our sales commitments and maintain a working inventory we purchased 11.3 million pounds of uranium at an average cost of $59.42 (US) per pound. While the unit cost of our purchases is significantly higher than the average production costs at McArthur River/Key Lake and Cigar Lake in 2023, we benefit from higher prices under the market-related portion of our long-term contract portfolio and higher prices benefit the pounds we have under negotiation. See 2023 financial results by segment – Uranium starting on page 61 for more information.

Thanks to our disciplined strategy, our balance sheet is strong, and we expect it will enable us to continue executing our strategy as well as to self-manage risk, including from global macro-economic uncertainty and volatility. As of December 31, 2023, we had $567 million in cash and cash equivalents with $1.8 billion in total debt. In addition, we have a $1.0 billion undrawn credit facility.

On November 7, 2023, we announced the closing of the acquisition of Westinghouse Electric Company (Westinghouse) in a strategic partnership with Brookfield Asset Management alongside its publicly listed affiliate Brookfield Renewable Partners (Brookfield) and institutional partners. Cameco now owns a 49% interest and Brookfield owns the remaining 51% in Westinghouse. We believe bringing together our expertise in the nuclear industry with Brookfield’s expertise in clean energy positions nuclear power at the heart of the clean energy transition and creates a powerful platform for strategic growth across the nuclear sector. See Westinghouse Electric Company beginning on page 94 for more information.

In the current environment, we believe the risk to uranium supply is greater than the risk to uranium demand and expect it will create a renewed focus on ensuring availability of long-term supply to fuel nuclear reactors. With the improvements in the market and to help meet our sales commitments, we plan to produce 18 million pounds (100% basis) at each of McArthur River/Key Lake and Cigar Lake in 2024. Based on KAP’s announcement on February 1, 2024, production in Kazakhstan is expected to remain 20% below the level stipulated in subsoil use agreements, similar to in 2023, primarily due to the sulfuric acid shortage in the country. We are still in discussions with JV Inkai and KAP to determine how this may impact production at Inkai in 2024 and thereafter and therefore our corresponding purchase obligation. We also plan to begin the work necessary to extend the mine life at Cigar Lake to 2036, subject to approval of Orano’s board, which we expect will be granted in the first quarter of 2024. In addition, at McArthur River/Key Lake, we plan to undertake an evaluation of the work and investment necessary to expand production up to its annual licensed capacity of 25 million pounds (100% basis), which we expect will allow us to take advantage of this opportunity when the time is right. See Uranium – Tier-one operations starting on page 73 for more information.

If we took advantage of all of the tier-one expansion opportunities available to us, our annual share of tier-one supply could be about 32 million pounds. However, we will continue to align our production with our contract portfolio and market opportunities, demonstrating that we continue to responsibly manage our supply in accordance with our customers’ needs.

In addition to our uranium production, at our Port Hope UF₆ conversion facility we plan to produce 12,000 tonnes in 2024 to satisfy our book of long-term business and demand for conversion services, at a time when conversion prices are at historic highs.

We will continue to look for opportunities to improve operational effectiveness, to improve our safety performance and reduce our impact on the environment, including through the use of digital and automation technologies to allow us to operate our assets with more flexibility and efficiency. This is key to our ability to continue to align our production decisions with our contract portfolio commitments and opportunities. With a solid base of contracts to underpin our productive capacity, and a growing contracting pipeline we plan to return to our tier-one cost structure, which we expect will generate strong financial performance.

As we execute on our strategy, we will continue to focus on protecting the health and safety of our employees, delivering our products safely and responsibly and addressing the ESG risks and opportunities that we believe will make our business sustainable and will build long-term value.

¹	Average of prices reported by TradeTech and UxC, LLC (UxC)

On the spot market, where purchases call for delivery within one year, the volume reported by UxC for 2023 decreased to 55 million pounds U₃O₈ equivalent, compared to 62 million pounds U₃O₈ equivalent in 2022. In 2023, total spot purchases by producers, junior uranium companies, financial funds and intermediaries was approximately 42 million pounds U₃O₈ equivalent, compared to approximately 53 million pounds U₃O₈ equivalent in 2022; in 2023, these purchases represented over 75% of spot market purchases compared to over 85% in 2022. At the end of 2023, the average reported spot price was $91.00 (US) per pound, up $43.33 (US) per pound from the end of 2022. During the year, the uranium spot price ranged from a month-end low of $50.48 (US) per pound to a month-end high of $91.00 (US) per pound, averaging $62.51 (US) for the year.

Long-term contracts generally call for deliveries to begin more than two years after the contract is finalized, and use a number of pricing formulas, including base-escalated prices set at time of contracting and escalated over the term of the contract, and market referenced prices (spot and long-term indicators) determined near the time of delivery, which also often include floor

prices and ceiling prices that are also escalated to time of delivery. The volume of long-term contracting reported by UxC for 2023 was about 160 million pounds U₃O₈ equivalent, up from about 125 million pounds U₃O₈ equivalent in 2022, including two contracts that combined totaled over 60 million pounds. Higher volumes can largely be attributed to utilities turning their attention to securing their long-term fuel needs to support the durable growth in demand for nuclear power and in light of the growing uncertainty of supply driven by heightened geopolitical tensions, and ongoing production challenges. The average reported long-term price at the end of the year was $68.00 (US) per pound, up $16.00 (US) from the end of 2022. During the year, the uranium long-term price steadily increased from a month-end low of $52.50 (US) per pound in January to a high of $68.00 (US) per pound in December, averaging $58.20 (US) for the year.

Since the Russian invasion of Ukraine in February 2022, conversion prices in both the North American and European markets have continued to increase. At the end of 2023, the average reported spot price for North American delivery reached a record high of $46.00 (US) per kilogram uranium as UF₆ (US/kgU as UF₆), up $6.00 (US) from the end of 2022. Long-term UF₆ conversion prices for North American delivery finished 2023 at $34.25 (US/kgU as UF₆), up $7.00 (US) from the end of 2022.

MANAGEMENT’S DISCUSSION AND ANALYSIS 21

Our vision, values and strategy

Our vision

Our vision – “Energizing a clean-air world” – recognizes that we have an important role to play in enabling the vast reductions in global GHG emissions required to achieve a resilient net-zero carbon economy. We support climate action that is consistent with the ambition of the Paris Agreement and the Canadian government’s corresponding commitment to limit global temperature rise to less than 2°C. We believe that this means the world needs to reach net-zero emissions by 2050 or sooner. The uranium we produce is used around the world in the generation of safe, carbon-free, affordable, base-load nuclear power.

We believe we have the right strategy to achieve our vision and we will do so in a manner that reflects our values. For 35 years, we have been delivering our products responsibly. Building on that strong foundation, we remain committed to our efforts to reduce our own, already low, greenhouse gas footprint in our ambition to reach net-zero emissions, while identifying and addressing the ESG risks and opportunities that we believe may have a significant impact on our ability to add long-term value for our stakeholders.

Committed to our values

Our values are discussed below. They define who we are as a company, are at the core of everything we do and help to embed ESG principles and practices as we execute on our strategy in pursuit of our vision. They are:

•

safety and environment

•

people

•

integrity

•

excellence

SAFETY AND ENVIRONMENT

The safety of people and protection of the environment are the foundations of our work. All of us share in the responsibility of continually improving the safety of our workplace and the quality of our environment.

We are committed to keeping people safe and conducting our business with respect and care for both the local and global environment.

22 CAMECO CORPORATION

Our strategy

We are a pure-play investment in the growing demand for nuclear energy, focused on taking advantage of the near-, medium-, and long-term growth occurring in our industry. We provide nuclear fuel and nuclear power products, services, and technologies across the fuel cycle, augmented by our investment in Westinghouse, that support the generation of clean, reliable, secure, and affordable energy. Our strategy is set within the context of what we believe is a transitioning market environment. Increasing populations, a growing focus on electrification and decarbonization, and concerns about energy security and affordability are driving a global focus on tripling nuclear power capacity by 2050, which is expected to durably strengthen the long-term fundamentals for our industry. Nuclear energy must be a central part of the solution to the world’s shift to a low-carbon, climate resilient economy. It is an option that can provide the power needed, not only reliably, but also safely and affordably, and in a way that will help avoid some of the worst consequences of climate change.

Our strategy is to capture full-cycle value by:

•

remaining disciplined in our contracting activity, building a balanced portfolio in accordance with our contracting framework

•

profitably producing from our tier-one assets and aligning our production decisions in all segments of the fuel cycle with contracted demand and customer needs

•

being financially disciplined to allow us to:

•

execute our strategy

•

invest in new opportunities that are expected to add long-term value

•

to self-manage risk

•

exploring other emerging opportunities within the nuclear power value chain, which align with our commitment to manage our business responsibly and sustainably, contribute to decarbonization, and help to provide secure and affordable energy

We expect our strategy will allow us to increase long-term value, and we will execute it with an emphasis on safety, people and the environment.

URANIUM

Uranium production is central to our strategy, as it is the biggest value driver of the nuclear fuel cycle and our business. We have tier-one assets that are licensed, permitted, long-lived, and are proven reliable with capacity to expand. These tier-one assets are backed up by idle tier-two assets and what we think is the best exploration portfolio of mineral reserves and resources that in some cases can leverage our existing infrastructure. Currently, we believe that we have ample productive capacity with the ability to expand as the demand for nuclear energy and nuclear fuel grows.

We are focused on protecting and extending the value of our contract portfolio, on aligning our production decisions with our contract portfolio and market opportunities thereby optimizing the value of our lowest cost assets. We also prioritize maintaining a strong balance sheet, and on efficiently managing the company. We have undertaken a number of deliberate and disciplined actions, including a focus on operational effectiveness to allow us to operate our assets more efficiently and with more flexibility.

FUEL SERVICES

Our fuel services segment supports our strategy to capture full-cycle value by providing our customers with access to refining and conversion services for both heavy-water and light-water reactors, and CANDU fuel and reactor component manufacturing for heavy-water reactors.

As in our uranium segment, we are focused on securing new long-term contracts and on aligning our production decisions with our contract portfolio that will allow us to continue to profitably produce and consistently support the long-term needs of our customers.

In addition, we are pursuing non-traditional markets for our UO₂ and fuel fabrication business and have been actively securing new contracts for reactor components to support refurbishment of Canadian reactors.

WESTINGHOUSE

In 2023, we completed the acquisition of Westinghouse, a global provider of mission-critical and specialized technologies, products and services for light-water reactors across most phases of the nuclear power sector, in a strategic partnership with Brookfield. We own a 49% interest in Westinghouse.

MANAGEMENT’S DISCUSSION AND ANALYSIS 23

We are enhancing our ability to compete for more business by investing in additional nuclear fuel cycle assets that we expect will augment the core of our business and offer more solutions to our customers across the nuclear fuel cycle. Like Cameco, Westinghouse has nuclear assets that are strategic, proven, licensed and permitted, and that are in geopolitically attractive jurisdictions. We expect these assets, like ours, will participate in the growing demand profile for nuclear energy.

Westinghouse has a stable and predictable core business generating durable cash flows. Like Cameco, Westinghouse has a long-term contract portfolio, which we believe positions it well to compete for growing demand for new nuclear reactors and reactor services, as well as the fuel supplies and services needed to keep the global reactor fleet operating safely and reliably. This strong base of business also helps protect Westinghouse from macro-economic headwinds as utility customers run their critical nuclear power plants. Its durable and growing business is expected to allow Westinghouse to self-fund its approved annual operating budget, to service its annual financial obligations from de-risked cash flows, and to pay annual distributions to its owners. See Westinghouse starting on page 94 for more information.

OTHER NUCLEAR FUEL CYCLE INVESTMENTS

We continually evaluate investment opportunities within the nuclear fuel value chain, which align well with our commitment to manage our business responsibly and sustainably, increase our contributions to decarbonization and help provide energy security. Expanding our participation in the fuel cycle is expected to complement our tier-one uranium and fuel services assets, creating new revenue opportunities, and it enhances our ability to meet the increasing needs of existing and new customers for secure, reliable nuclear fuel supplies, services and technologies.

In particular, we are interested in the second largest value driver of the fuel cycle, enrichment, and have a 49% interest in Global Laser Enrichment LLC (GLE). GLE is the exclusive licensee of the proprietary SILEX laser enrichment technology, a third-generation uranium enrichment technology. We are the commercial lead for the GLE project with an option to attain a majority interest of up to 75% ownership. See Global Laser Enrichment starting on page 99 for more information.

Additionally, we have signed a number of non-binding arrangements to explore several areas of cooperation to advance the commercialization and deployment of small modular reactors in Canada and around the world.

We will make an investment decision when an opportunity is available at the right time and the right price. We strive to pursue corporate development initiatives that will leave us and our stakeholders in a fundamentally stronger position. As such, an investment opportunity is never assessed in isolation. Investments must compete for investment capital with our own internal growth opportunities. They are subject to our capital allocation process described under Capital Allocation – Focus on Value, starting on page 30.

BUILDING A BALANCED PORTFOLIO

The purpose of our contracting framework is to deliver value. Our approach is to secure a solid base of earnings and cash flow by maintaining a balanced contract portfolio that optimizes our realized price.

Contracting decisions in all segments of our business need to consider the nuclear fuel market structure, the nature of our competitors, and the current market environment. The vast majority of run-rate fuel requirements are procured under long-term contracts. The spot market is thinly-traded where utilities buy small, discretionary volumes. This market structure is reflective of the baseload nature of nuclear power and the relatively small proportion of the overall operating costs the fuel represents compared to other sources of baseload electricity. Additionally, about half of the fuel supply typically comes from diversified mining companies that produce uranium as a by-product, or by state-owned entities with production volume strategies or ambitions to serve state nuclear power ambitions with low-cost fuel supplies. We evaluate our strategy in the context of our market environment and continue to adjust our actions in accordance with our contracting framework:

•

First, we build a long-term contract portfolio by layering in volumes over time. In addition to our committed sales, we will compete for customer demand in the market where we think we can obtain value and, in general, as part of longer-term contracts. We will take advantage of opportunities the market provides, where it makes sense from an economic, logistical, diversification and strategic point of view. Those opportunities may come in the form of spot, mid-term or long-term demand, and will be additive to our current committed sales.

•

As we build our portfolio of long-term contracts, we decide how to best source material to satisfy that demand, planning our production in accordance with our contract portfolio and other available sources of supply. We will not produce from our tier-one assets to sell into an oversupplied spot market.

24 CAMECO CORPORATION

•

We do not intend to build an inventory of excess uranium. Excess inventory serves to contribute to the sense that uranium is abundant and creates an overhang on the market, and it ties up working capital on our balance sheet.

•

Depending on the timing and volume of our production, purchase commitments, and our inventory volumes, we may be active buyers in the market in order to meet our annual delivery commitments. Historically, prior to the supply curtailments that we began in 2016, we have generally planned our annual delivery commitments to slightly exceed the annual supply we expect to come from our annual production and our long-term purchase commitments and have therefore relied on the spot market to meet a small portion of our delivery commitments. In general, if we choose to purchase material to meet demand, we expect the cost of that material will be more than offset by the volume of commitments in our sales portfolio that are exposed to market prices at the time of delivery over the long-term.

In addition to this framework, our contracting decisions always factor in who the customer is, our desire for regional diversification, the product form, and logistical factors.

Ultimately, our goal is to protect and extend the value of our contract portfolio on terms that recognize the value of our assets, including future development projects, and pricing mechanisms that provide adequate protection when prices go down and exposure to rising prices. We believe using this framework will allow us to create long-term value. Our focus will continue to be on ensuring we have the financial capacity to execute on our strategy and self-manage risk.

LONG-TERM CONTRACTING

Uranium is not traded in meaningful quantities on a commodity exchange. Utilities have historically bought the majority of their uranium and fuel services products under long-term contracts that are bilaterally negotiated with suppliers. The spot market is discretionary and typically used for one-time volumes, not to satisfy annual demand. We sell uranium and fuel products and services directly to nuclear utilities around the world as uranium concentrates, UO₂ and UF₆, conversion services, or fuel fabrication and reactor components for CANDU heavy water reactors. We have a solid portfolio of long-term sales contracts that reflect our reputation as a proven, reliable supplier of geographically stable supply, and the long-term relationships we have built with our customers.

In general, we are active in the market, buying and selling uranium when it is beneficial for us and in support of our long-term contract portfolio. We undertake activity in the spot and term markets prudently, looking at the prices and other business factors to decide whether it is appropriate to purchase or sell into the spot or term market. Not only is this activity a source of profit, but it also gives us insight into underlying market fundamentals.

We deliver the majority of our uranium under long-term contracts each year, some of which are tied to market-related pricing mechanisms quoted at time of delivery. Therefore, our net earnings and operating cash flows are generally affected by changes in the uranium price. Market prices are influenced by the fundamentals of supply and demand, market access and trade policy issues, geopolitical events, disruptions in planned supply and demand, and other market factors.

The objectives of our contracting strategy are to:

•

optimize realized price by balancing exposure to future market prices while providing some certainty for our future earnings and cash flow

•

focus on meeting the nuclear industry’s growing annual uncovered requirements with our tier-one production

•

establish and grow market share with strategic and regionally diverse customers

We have a portfolio of long-term contracts, each bilaterally negotiated with customers, that have a mix of base-escalated pricing and market-related pricing mechanisms, including provisions that provide exposure to rising market prices and also protect us when the market price is declining. This is a balanced and flexible approach that allows us to adapt to market conditions, put a floor on our average realized price and deliver the best value over the long term.

This approach has allowed our realized price to outperform the market during periods of weak uranium demand, and we expect it will enable us to realize increases linked to higher market prices in the future.

Base-escalated contracts for uranium: use a pricing mechanism based on a term-price indicator at the time the contract is accepted and escalated to time of each delivery over the term of the contract.

MANAGEMENT’S DISCUSSION AND ANALYSIS 25

Market-related contracts for uranium: are different from base-escalated contracts in that the pricing mechanism may be based on either the spot price or the long-term price, and that price is generally set a month or more prior to delivery rather than at the time the contract is accepted. These contracts may provide for discounts, and typically include floor prices and/or ceiling prices, which are established at time of contract acceptance and usually escalate over the term of the contract.

Fuel services contracts: the majority of our fuel services contracts use a base-escalated mechanism per kgU and reflect the market at the time the contract is accepted.

OPTIMIZING OUR CONTRACT PORTFOLIO

We work with our customers to optimize the value of our contract portfolio. With respect to new contracting activity, there is often a lag from when contracting discussions begin and when contracts are executed. With our large pipeline of business under negotiation in our uranium segment, and a value driven strategy, we continue to be strategically patient in considering the commercial terms we are willing to accept. We layer in contracts over time, with higher commitments in the near term and declining over time in accordance with utilities growing uncovered requirements. Demand may come in the form of off-market negotiations or through on-market requests for proposals. We remain confident that we can add acceptable new sales commitments to our portfolio of long-term contracts to underpin the ongoing operation of our productive capacity and capture long-term value.

Given our view that additional long-term supply will need to be incented to meet the growing demand for safe, clean, reliable, carbon-free nuclear energy, our preference today is to sign long-term contracts with market-related pricing mechanisms. However, we believe our customers expect prices to rise and prefer to lock-in today’s prices, with a fixed-price mechanism. Our goal is to balance all these factors, along with our desire for customer and regional diversification, with product form, and logistical factors to ensure we have adequate protection and will have exposure to rising market prices under our contract portfolio, while maintaining the benefits that come from having low-cost supply to deliver into a strengthening market.

With respect to our existing contracts, at times we may also look for opportunities to optimize the value of our portfolio. In cases where there is a changing policy, operating, or economic environment, we may consider adjusting our contracts in a manner that allow us to maintain our customer relationships and is mutually beneficial.

CONTRACT PORTFOLIO STATUS

We have executed contracts to sell approximately 205 million pounds of U₃O₈ with 37 customers worldwide in our uranium segment, and over 75 million kilograms as UF₆ conversion with 33 customers worldwide in our fuel services segment.

Customers – U₃O₈:

Five largest customers account for 62% of commitments

LOGO

MANAGING OUR CONTRACT COMMITMENTS

We allow sales volumes to vary year-to-year depending on:

•

the level of sales commitments in our long-term contract portfolio

•

market opportunities

•

our sources of supply

To meet our delivery commitments and to mitigate risk, we have access to a number of sources of supply, which includes uranium obtained from:

•

our productive capacity

•

purchases under our JV Inkai agreement, under long-term agreements and in the spot market

•

our inventory in excess of our working requirements

•

product loans

OUR SUPPLY DISCIPLINE

As spot is not the fundamental market, true value is built under a long-term contract portfolio and is measured over the full commodity cycle. Therefore, we align our uranium production decisions with our contract commitments and market opportunities to avoid carrying excess inventory or having to sell into an oversupplied spot market. In accordance with market conditions, and to mitigate risk, we evaluate the optimal mix of our production, inventory and purchases in order to satisfy our contractual commitments and in order to realize the best return over the entire commodity cycle. During a prolonged period of uncertainty, this could mean leaving our uranium in the ground. For the years 2016 through 2022, we left more than 130 million pounds of uranium in the ground (100% basis) by curtailing our production. We purchased more than 60 million pounds including spot and long-term purchases and in 2018 we drew down our inventory by almost 20 million pounds. That totals over 210 million pounds (100% basis) of uranium that were not available to the market.

However, today we believe the uranium market is in transition, driven by the growing demand for nuclear energy and the increasing recognition that it is essential to the clean-energy transition and to energy security. As the market continues to transition, we expect to continue placing our uranium under long-term contracts and meet rising demand with production from our best margin operations.

MANAGEMENT’S DISCUSSION AND ANALYSIS 27

With the improvements in the market, the new long-term contracts we have put in place, and a pipeline of contracting discussions, we plan to produce 18 million pounds (100% basis) at McArthur River/Key Lake and Cigar Lake in 2024. Based on KAP’s announcement on February 1, 2024, production in Kazakhstan is expected to remain 20% below the level stipulated in subsoil use agreements, similar to in 2023, primarily due to the sulfuric acid shortage in the country. We are still in discussions with JV Inkai and KAP to determine how this may impact production at Inkai in 2024 and thereafter and therefore our corresponding purchase obligation. We also plan to begin the work necessary to extend the mine life at Cigar Lake subject to approval of Orano’s board. In addition, we plan to undertake the evaluation of the work and investment necessary to expand production at McArthur River/Key Lake up to its annual licensed capacity of 25 million pounds, which we expect will allow us to take advantage of this opportunity when the time is right.

Our production decisions will continue to be aligned with market opportunities and our ability to secure the appropriate long-term contract homes for our unencumbered, in-ground inventory, demonstrating that we continue to responsibly manage our assets in accordance with our customers’ needs.

In addition to our uranium production plans, we plan to produce 12,000 tonnes at our Port Hope UF₆ conversion facility in 2024 to satisfy our book of long-term business for conversion services and customer demand, at a time when conversion prices are at historic highs.

Our production plans for McArthur River/Key Lake and Cigar Lake are expected to generate strong financial performance by allowing us to source more of our committed sales from the lower-cost produced pounds. In addition, with conversion demand elevated, we have been successful in securing long-term sales commitments that will support increased UF₆ production at Port Hope, which is expected to further improve its contribution to our financial results. However, this is not an end to our supply discipline. We expect to continue to adjust our production in accordance with our contract portfolio. This will remain our production plan until we see further improvements in the uranium market and contracting progress, once again demonstrating that we are a responsible fuel supplier.

MANAGING OUR COSTS

Production costs

In order to operate efficiently and cost-effectively, we manage operating costs and improve plant reliability by prudently investing in production infrastructure, new technology, and business process improvements. Like all mining companies, our uranium segment is affected by the cost of inputs such as labour and fuel.

LOGO

*	Production supplies include reagents, fuel and other items. Contracted services include utilities and camp costs, air charters, mining and maintenance contractors and security and ground freight.

28 CAMECO CORPORATION

Over the last number of years, the annual cash cost of production reflected the operating cost of mining and milling our share of Cigar Lake as this was our only operating site. With the restart of the McArthur River/Key Lake operations the annual cost of production will reflect a combined cost of all our operating uranium assets. See 2023 financial results by segment – Uranium starting on page 61 for more information. In 2024, our cash production costs may continue to be affected by inflation, the availability of personnel with the necessary skills and experience, supply chain challenges impacting the availability of materials and reagents, and our continued efforts to ramp up to planned production at McArthur River/Key Lake.

Operating costs in our fuel services segment are mainly fixed. In 2023, labour accounted for about 56% of the total. The largest variable operating cost is for anhydrous hydrogen fluoride, followed by zirconium, and energy (natural gas and electricity).

We continue to look to adopt innovative and advanced digital and automation technologies to improve efficiency and operational flexibility and to further reduce cost.

Care and maintenance costs

In 2024, we expect to incur between $50 million and $60 million in care and maintenance costs related to the suspension of production at our Rabbit Lake mine and mill, and our US operations. Production at these operations are higher-cost and a restart is less certain. We continue to evaluate our options in order to minimize these costs.

Purchases and inventory costs

Our costs are also affected by the purchases of uranium and conversion services we make under long-term contracts and on the spot market.

To meet our delivery commitments, we make use of our mined production, inventories, purchases of our share of material from Inkai, purchases under long-term contracts, purchases we make on the spot market and product loans. In 2024, we expect the price for the majority of our purchases will be quoted at the time of delivery.

The cost of purchased material may be higher or lower than our other sources of supply, depending on market conditions. The cost of purchased material affects our cost of sales, which is determined by calculating the average of all of our sources of supply, including opening inventory, production, and purchases, and adding royalties, selling costs, and care and maintenance costs. Our cost of sales could be impacted if we do not achieve our annual production plan, or if we are unable to source uranium as planned, and we are required to purchase uranium at prices that differ from our cost of inventory.

Financial impact

The growing demand for nuclear power due to its safety, clean energy, reliability, security and affordability attributes has contributed to increased demand for nuclear fuel products and services. As a result, we have seen significant price increases across the nuclear fuel value chain, which reflect the need for capacity increases to satisfy the projected growth.

The deliberate and disciplined actions we took to curtail production and streamline operations over the past decade came with near-term costs like care and maintenance costs, operational readiness costs, and purchase costs higher than our production costs. However, we considered these costs as investments in our future.

Today, thanks to our investments, and with our continued ability to secure new long-term sales commitments, we believe we are well-positioned for growth. Our core growth is expected to come from our existing tier-one mining and fuel services assets. We do not have to build new capacity to pursue new opportunities. We have sufficient productive capacity to expand, a position we have not enjoyed in previous price cycles.

And, with the acquisition of a 49% interest in Westinghouse, we expect to be able to expand our growth profile by extending our reach in the nuclear fuel cycle at a time when there are tremendous tailwinds for the nuclear power industry. We are extending our reach with an investment in assets, that like ours, are strategic, proven, licensed and permitted, that are located in geopolitically favourable jurisdictions, and that we expect will be able to grow from their existing footprint. These assets are also expected to provide new opportunities for our existing suite of uranium and fuel services assets.

We believe our actions and investments have helped position the company to self-manage risk and as we make the transition back to a tier-one run rate, we expect to generate strong financial performance, allowing us to execute on our strategy while rewarding our stakeholders for their continued patience and support of our strategy to build long-term value.

MANAGEMENT’S DISCUSSION AND ANALYSIS 29

CAPITAL ALLOCATION – FOCUS ON VALUE

Delivering long-term value is a top priority. While we navigate by our investment-grade rating, we continually evaluate our investment options to ensure we allocate our capital in a way that we believe will:

•

sustain our assets and grow our core business in a manner that we expect will create sustainable long-term value

•

maintain a strong balance sheet that will allow us to execute on our strategy, take advantage of strategic opportunities and self-manage risk

•

allow us to sustainably execute on our dividend while considering the cyclical nature of our earnings and cash flow

To deliver value, free cash flow must be productively reinvested in the business. We start by determining how much cash we have to invest (investable capital). Investable capital takes into account, our expected cash flow from operations, including the expected cash distributions from JV Inkai and our Westinghouse investment, minus the cash required to satisfy our financing costs, for working capital purposes, and the other uses of cash we consider to be higher priority, such as dividends. This investable capital can be reinvested in the core business of the company, including to manage the physical and transition risks and opportunities associated with changing climate conditions, or to take advantage of new opportunities in line with our long-term strategy. If after consideration of investment opportunities there is excess investable capital available, it can be considered for debt reduction, or shareholder returns.

Reinvestment

We have a multidisciplinary capital allocation committee that evaluates all sustaining, capacity replacement, or growth investment opportunities.

These opportunities are ranked using return criteria that includes both financial and non-financial metrics, with a current priority focus on five main value drivers:

•

cost reduction

•

emission reduction

•

operational flexibility

•

improving safety performance

•

enabling digital technology

Only those that meet the required risk-adjusted return criteria are considered for investment. We also must identify, at the corporate level, the expected impact on cash flow, earnings, and the balance sheet. All project risks must be identified, including the risks of not investing. Allocation of capital only occurs once an investment has cleared these hurdles.

This may result in some opportunities being held back in favour of higher return investments and should allow us to generate the best return on investment decisions when faced with multiple prospects, while also controlling our costs and meeting ESG objectives, including achieving the 30% reduction in our GHG emissions by 2030 compared to 2015 levels.

Return

We believe in returning cash to shareholders under appropriate circumstances but are also focused on protecting the company and rewarding those shareholders who understand and support our strategy to build long-term value. If we have excess cash and determine the best use is to return it to shareholders, we can do that through a share repurchase or dividend—an annual dividend, one-time supplemental dividend or a progressive dividend. The decision to return capital and the type of return is evaluated regularly by our board of directors with careful consideration of our cash flow, financial position, strategy, and other relevant factors including appropriate alignment with the cyclical nature of our earnings. For example, in 2022, the board increased the dividend by 50% to reflect the expected improvement in our financial performance as we began the transition to our tier-one run rate.

In Action

The current objective of our capital allocation will be to ensure we have the financial capacity to execute on our 2024 production plan and to return to our tier-one cost structure. In addition, we expect to allocate the capital necessary to allow us to begin work on extending the mine life at Cigar Lake and to undertake evaluation of the work and investment required to expand production at McArthur River/Key Lake up to its licensed capacity of 25 million pounds per year (100% basis).

30 CAMECO CORPORATION

We will maintain our focus on improving operational effectiveness across the company through for example, the use of digital and automation technologies. The particular goals of this work being to reduce operating costs, increase operational flexibility, improve our safety performance and reduce our impact on the environment, including the reduction of our GHG emissions.

Over the coming months, we will look for an opportunity to refinance the $500 million senior unsecured debenture maturing on June 24, 2024, prior to maturity or as it comes due. Ultimately our decision will be made with consideration for our cash generation, the interest rate environment and other capital allocation considerations. In addition, we have initiated a partial repayment of $200 million (US) on the $600 million (US) floating-rate term loan that was used to finance the acquisition of Westinghouse. The prepayment will be applied to the $300 million (US) tranche which matures in November 2026. See Liquidity and capital resources – Financing Activities starting on page 54 for more information about the term loan.

We will continue to navigate by our investment-grade rating through close management of our balance sheet metrics, maintaining sufficient liquidity, including a minimum cash balance for working capital requirements and that would allow us to pursue other value-adding opportunities. If the market transition continues as expected, our priorities might include consideration of:

•

the opportunities available to add value with our licensed and permitted tier-two assets and brownfield infrastructure

•

further value-adding opportunities in the nuclear fuel value chain

•

the return of excess cash to shareholders

Any opportunities will be rigorously assessed by our capital allocation committee before an investment decision is made.

Shares and stock options outstanding

At February 6, 2024, we had:

•

434,175,752 common shares and one Class B share outstanding

•

1,396,289 stock options outstanding, with exercise prices ranging from $11.32 to $16.38

Dividend

In 2023, our board of directors declared a dividend of $0.12 per common share, which was paid December 15, 2023. See the section titled Return on page 30 for more information regarding the factors the board considers in deciding to declare an annual dividend.

MANAGEMENT’S DISCUSSION AND ANALYSIS 31

Our ESG principles and practices

A key part of our strategy, reflecting our values

We are committed to delivering our products responsibly. We integrate ESG principles and practices into every aspect of our business, from our corporate objectives and approach to compensation, to our overall corporate strategy, risk management, and day-to-day operations, and they align with our values. We seek to be transparent with our stakeholders, keeping them updated on the risks and opportunities that we believe may have a significant impact on our ability to achieve our strategic plan and add long-term value. We recognize the importance of integrating certain ESG factors, such as safety performance, a clean environment and supportive communities, into our executive compensation strategy as we see success in these areas as critical to the long-term success of the company.

Our board of directors holds the highest level of oversight for our business strategy and strategic risks, including ESG matters and climate-related risks. Oversight of ESG and climate-related reporting and disclosure has been delegated by the board to the Safety, Health and Environment (SHE) committee of the board. We also have a multi-disciplinary ESG steering committee, chaired by our senior vice-president and chief corporate officer that includes representatives from across the organization whose role is to review our ESG governance and reporting, and our current approach to sustainability, against evolving trends. Additional information about our governance of ESG matters is included in our most recent ESG report.

In an effort to continually evolve the robustness of our sustainability commitments and communications, starting in 2020, we aligned our ESG performance indicators with the ones recommended by the Sustainability Accounting Standards Board (SASB). In addition, we began addressing the recommendations of the Task Force on Climate-Related Financial Disclosures (TCFD) in our ESG report. In 2022, we continued to progress our work, conducting a gap analysis to identify how we could better align to TCFD recommendations. Key findings from this work were actioned throughout 2022 and 2023, including the undertaking of physical and transition-related climate scenario analyses to inform our overarching climate strategy. In 2023, the IFRS published its first two sustainability standards, S1 sustainability disclosure standard and S2 climate-related disclosure via the International Sustainability Standards Board. While it is unclear when and to what extent the Canadian Securities Administrators may adopt these standards at this point, we have begun the work to better understand the requirements under these standards and how our current reporting aligns with these standards.

In July 2023, we published our 2022 ESG report. The report sets out our strategy and the policies and programs we use to govern and manage ESG issues that are important to our stakeholders. In addition to SASB and TCFD, the report provides key ESG performance indicator data based on the Global Reporting Initiative’s Sustainability Framework as well as some unique corporate indicators, to measure and report our performance on environmental, social and economic impacts in the areas we believe have a significant impact on our sustainability in the long-term and are important to our stakeholders. This is our ESG report card to our stakeholders. You can find our report at cameco.com/about/sustainability.

ENVIRONMENT

We recognize the critical nature of the fight against climate change, and want our employees, customers, investors, and community partners near our operations to know we are committed to being an active and constructive partner in addressing this challenge. The reduction of carbon and greenhouse gas (GHG) emissions is important and necessary in Canada and around the world. Policy makers and major industries recognize that nuclear power must be a central part of the solution to the world’s shift to a low-carbon, climate-resilient economy. Several nations have reaffirmed their commitments to nuclear power and are developing plans to support existing reactors and are reviewing their policies to encourage more nuclear capacity. There are now 28 countries that have signed on to the declaration that was launched at COP28 to triple nuclear energy capacity by 2050.

As one of the world’s largest producers of the uranium needed to fuel nuclear reactors, we believe this represents a significant opportunity for us to be part of the solution to combat climate change given 100% of our product is used to produce clean, carbon-free base-load electricity. We enable vast emissions reductions globally through nuclear power and are committed to transforming our already low operational GHG emissions footprint to achieve our ambition of having net-zero emissions while delivering significant long-term business value. In the 35 years we have been in business, we have sold over 954 million pounds of product for nuclear power generation. By reducing the need for fossil-fuel based electricity, this has avoided up to 16 billion tonnes of CO₂e emissions, equivalent to removing all gas-powered vehicles in the world from operation for 3.5 years.

32 CAMECO CORPORATION

Recently, we put further support behind our commitment to climate action and our vision of energizing a clean-air world by joining Net Zero Nuclear as a corporate partner. Net Zero Nuclear is an initiative between government, industry leaders and civil society to triple global nuclear capacity to achieve carbon neutrality by 2050. We join the initiative as a Gold Partner, deepening industry support for this initiative, which was launched by the World Nuclear Association and the Emirates Nuclear Energy Corporation, with the support of the Atoms4NetZero initiative launched by the International Atomic Energy Agency at the 2023 World Nuclear Symposium in London.

In 2022, we undertook a planning process to outline our overarching Low Carbon Transition Plan. Within this plan, we set a target to reduce our Scope 1 and 2 GHG emissions by 30% by 2030, from 2015 levels. We also identified the practical and achievable actions that we expect to take to decarbonize our operations and manage climate-related risks. In doing so, we are demonstrating our alignment with the ambitions of the Paris Agreement to, “limit global temperature rise to well below 2 degrees Celsius (°C), above pre-industrial levels, and to pursue efforts to limit global temperature rise even further to 1.5°C”. Our Low Carbon Transition Plan provides a foundation for managing our climate-related physical and transition risks, and it supports us in better aligning with the Government of Canada’s Net Zero Accountability Act and 2030 Emission Reduction Plan.

We recognize that climate change, including shifts in temperature, precipitation and more frequent severe weather events could affect our operations in a range of possible ways. As part of our Low Carbon Transition Plan, we have completed climate change scenario analyses to understand how projected long-term changing climate conditions could impact our employees, assets, and operations in northern Saskatchewan and Ontario, Canada. We leveraged internal subject matter expertise with help from a third-party expert to complete the assessments.

The physical risk assessment studies were undertaken to deliver initial forward-looking physical climate risk assessments and identify possible risk management and adaptation options across our mining, milling and fuel services operations. In 2024, we will focus on updating the findings from these physical climate risk assessments into our internal risk management review and developing an adaptation action plan template. The template will support the development of site-specific adaptation plans for each of our Canadian operations. We are targeting the completion of physical climate risk assessments for all our majority owned and operated facilities by the end of 2026.

We will continue to explore climate change projections for the areas where we operate and those critical to moving supplies and products through our value chain. We will use this information to identify where our existing climate-related acute and chronic risk management practices are expected to remain sufficient in the years to come and where adaptation and other enhancements may be required.

When it comes to climate change, we have tracked and reported our GHG emissions for more than two decades. A summary of our activities to understand and mitigate the risks associated with climate change scenarios is reported to the board of directors on a regular basis in accordance with our Enterprise Risk Management program, including the mitigating controls and management actions taken to reduce these risks.

To support achieving our 2030 GHG emissions reduction target, we implemented a 2023 compensable target to create tailored decarbonization pathways for each operationally controlled site. The 2023 work included an evaluation of over 160 decarbonization project ideas solicited from across the organization. Project ideas were evaluated based on cost, emissions reduction potential, implementation timeline, and other co-benefits as outlined by the climate action factors recently integrated within our Capital Allocation Committee process. The site-specific decarbonization pathways also included the development of practical project implementation timelines considering life of asset plans for each operation and technological readiness of the relevant technologies. Decarbonization efforts are already underway across our five decarbonization themes: efficiency, electrification, waste to value, fuel switching and carbon economy.

MANAGEMENT’S DISCUSSION AND ANALYSIS 33

Over the past few years, we have put significant effort towards efficiency, our first decarbonization theme. We have been focused on improving the visibility of energy consumption within our organization and implementing improvements to reduce energy consumption. We have already enjoyed some significant success in our efforts to reduce our energy use and GHG emissions to date. For example, at our Port Hope conversion facility, we have achieved a 28% reduction to peak power demand and more than $2.1 million in annual energy savings with projects such as HVAC and compressed air system upgrades and lighting efficiency retrofits. In 2023, the Port Hope Closed Loop Cooling Water system was commissioned, eliminating the need to draw water from the nearby harbour. With the new closed loop system, the operation is no longer dependent on the temperature or quality of the lake water. This project has positive benefits for both the overall reliability and our environmental footprint, decreasing the energy required to change the temperature of the water and eliminating the risk of environmental releases to the lake.

At our northern Saskatchewan mining and milling operations, recent efforts have focused on the implementation of an Energy Management Information System (EMIS) in alignment with our larger digital transformation efforts. The EMIS improves our ability to visualize, monitor, and manage our energy use and emissions profile in real time. Ultimately, EMIS gives those operations the ability to identify where our highest impact emissions reduction opportunities exist and assurance that the actions we have taken are maintained over time. Two projects were advanced in 2023 at our northern Saskatchewan operations: LED lighting updates to Key Lake and Ventilation-on-Demand at McArthur River. At Key Lake, we have made upgrades in lighting, updating to LED, translating to annual reductions of approximately 725,000 kWh electricity savings or 375 tonnes of CO₂e. Additionally, this project improves operator comfort and safety when working in these areas. At McArthur River, the Ventilation-on-Demand project is currently underway. It includes mine ventilation upgrades to surface heater fans and underground ventilation dampers to enable a reduction in both electricity and propane consumption.

SOCIAL

Our relationships with our workforce, Indigenous Peoples, and local communities are fundamental to our success. The safety and protection of our workforce and the public is our top priority in our assessment of risk and planning for safe operations and product transport. To deliver on our vision, we invest in programs to attract and retain a diverse and skilled workforce that better reflects the communities in which we operate and to increase the participation of underrepresented groups in trades and technical positions. We want to build a workforce that is dedicated to continuous improvement and shares our values.

We have a five-pillar approach to develop and maintain long-term relationships and provide opportunities to those living in areas near our operations. The five-pillars include workforce development, business development, community investment, environmental stewardship, and community engagement. To strengthen relationships and shape them into mutually beneficial partnerships, we have collaboration agreements in northern Saskatchewan and Ontario that follow this approach. These agreements allow us to collaboratively determine focus areas based on a community’s unique needs, optimizing benefits to the community, providing certainty around community investment and local business opportunities.

GOVERNANCE

We believe that sound governance is the foundation for strong corporate performance. Our diverse and independent board of directors’ primary role is to provide strategic direction and risk oversight in order to help the company achieve its vision of “energizing a clean-air world”. The board guides the company to operate as a sustainable business, to optimize financial returns while effectively managing risk, and to conduct business in a way that is transparent, independent, and ethical.

The board has formal governance guidelines that set out our approach to governance and the board’s governance role and practices. The guidelines ensure we comply with all of the applicable governance rules and legislation in Canada and the US, conduct ourselves in the best interests of our stakeholders, and meet industry best practices. The guidelines are reviewed and updated regularly.

Our corporate governance framework includes an established and recognized management system that describes the policies, processes and procedures we use to help us fulfill all the tasks required to achieve our objectives and strategy. It sets out our vision, values, and measures of success. It speaks to our strategic planning process, leadership alignment and accountability, compliance and assessment, people and culture, process identification and work management, risk management, communications and stakeholder support, knowledge and information management, change management, problem identification and resolution, and continual improvement.

Risk and Risk Management

Our board of directors oversees management’s implementation of appropriate risk management processes and controls. We have a Risk Policy that is supported by our formal Risk Management Program.

Our Risk Management Program involves a broad, systematic approach to identifying, assessing, monitoring, reporting and managing the significant risks we face in our business and operations, including consideration of ESG and climate-related risks and cyber risks that could impact our four measures of success. The program is based on the ISO 31000 Risk Management guidelines. ISO 31000 provides guidance on risk management activities with internationally recognized practices and provides sound principles for effective management and governance of risks. Our program applies to all risks facing the company, including climate-related risks. The program establishes clear accountabilities for employees throughout the company to take ownership of risks specific to their area and to effectively manage those risks. The program is reviewed annually to ensure that it continues to meet our needs.

We use a common risk matrix throughout the company. Any risk that has the potential to significantly affect our ability to achieve our corporate objectives or strategic plan is considered an enterprise risk and is brought to the attention of senior management and the board. We continually update our risk profile by performing regular monitoring of risks across the organization. Regular monitoring helps us to properly manage risks and identify any new risks. Detailed risk reporting is provided on a quarterly basis to senior management and the board and its committees on the status of the mitigating and/or monitoring plans for each of the enterprise risks. Management also reviews monthly updates on the company’s progress in managing these risks.

In addition to considering the other information in this MD&A, you should carefully consider the material risks discussed starting on page 4, under the heading Managing the risks, starting on page 70, and the specific risks discussed under each operation, advanced project, and other fuel cycle investment update in this document. These risks, however, are not a complete list of the potential risks our operations, advanced projects, or other investments face. There may be others we are not aware of or risks we feel are not material today that could become material in the future.

We recommend you also review our annual information form, which includes a discussion of other material risks that could have an impact on our business.

MANAGEMENT’S DISCUSSION AND ANALYSIS 35

Measuring our results

Targets and Metrics: The link between ESG factors and executive pay

Each year, we set corporate objectives that are aligned with our strategic plan. These objectives fall under our four measures of success: outstanding financial performance, safe, healthy and rewarding workplace, clean environment and supportive communities. Performance against specific targets under these objectives forms the foundation for a portion of annual employee and executive compensation. See our most recent management proxy circular for more information on how executive compensation is determined.

While we saw a significant improvement in our financial performance (earnings and cash flow) as our tier-one production increases and our average realized price reflects the improving market, our results still do not reflect our expected long-term run rate performance. As our long-term contract portfolio continues to grow and our tier-one production continues to ramp up, we believe that the strategic actions we have taken have helped to pave the way to stronger financial performance over time. Additionally, we will not compromise our commitment to safety, people and our environment.

2023 consolidated financial results

During the fourth quarter, we announced the closing of the acquisition of a 49% interest in Westinghouse. Effective November 7, 2023, we began equity accounting for this investment. Our share of Westinghouse’s earnings has been reflected in our financial results from that date.

In the second quarter of 2022, we along with Orano acquired Idemitsu Canada Resources Ltd.’s 7.875% participating interest in the Cigar Lake Joint Venture. Our ownership stake in Cigar Lake now stands at 54.547%, 4.522 percentage points higher than it was prior to the transaction. Effective May 19, 2022, we have reflected our share of production and financial results based on this new ownership stake.

See 2023 Financial results by segment on page 61 for more detailed discussion.

THREE-YEAR TREND

In 2022, revenue increased by 27% compared to 2021 due to an increase in the average realized price and sales volume in the uranium segment. In our fuel services segment, revenue decreased by 10% as a result of a decrease in sales volume partially offset by an increase in average realized price.

In 2023, revenue increased by 39% compared to 2022 due to a 45% increase in the uranium segment and a 17% increase in our fuel services segment. Both segments saw increases in the average realized price and sales volume. See notes 18 and 29 in our annual financial statements for more information.

SALES DELIVERY OUTLOOK FOR 2024

For 2024 we have committed sales volumes in our uranium segment of between 32 and 34 million pounds. In general, we are active in the market, buying and selling uranium when it is beneficial for us and in support of our long-term contract portfolio.

40 CAMECO CORPORATION

In our uranium and fuel services segments, our customers choose when in the year to receive deliveries. As a result, our quarterly delivery patterns and, therefore, our sales volumes and revenue can vary significantly. We expect the quarterly distribution of uranium deliveries in 2024 to be more heavily weighted to the first and fourth quarters as shown below. However, not all delivery notices have been received to date and the expected delivery pattern could change. Typically, we receive notices six months in advance of the requested delivery date.

Non-IFRS measures

The non-IFRS measures referenced in this document are supplemental measures, which are used as indicators of our financial performance. Management believes that these non-IFRS measures provide useful supplemental information to investors, securities analysts, lenders and other interested parties in assessing our operational performance and our ability to generate cash flows to meet our cash requirements. These measures are not recognized measures under IFRS, do not have standardized meanings, and are therefore unlikely to be comparable to similarly-titled measures presented by other companies. Accordingly, these measures should not be considered in isolation or as a substitute for the financial information reported under IFRS. The following are the non-IFRS measures used in this document.

ADJUSTED NET EARNINGS

Adjusted net earnings (ANE) is our net earnings attributable to equity holders, adjusted for non-operating or non-cash items such as gains and losses on derivatives, adjustments to reclamation provisions flowing through other operating expenses, and bargain purchase gains, that we believe do not reflect the underlying financial performance for the reporting period. Other items may also be adjusted from time to time. We adjust this measure for certain of the items that our equity-accounted investees make in arriving at other non-IFRS measures. Adjusted net earnings is one of the targets that we measure to form the basis for a portion of annual employee and executive compensation (see Measuring our results starting on page 36).

MANAGEMENT’S DISCUSSION AND ANALYSIS 41

To facilitate a better understanding of these measures, the table below reconciles adjusted net earnings with our net earnings for the years ended 2023, 2022 and 2021.

EBITDA

ADJUSTED EBITDA

Adjusted EBITDA is defined as EBITDA, as further-adjusted for the impact of certain costs or benefits incurred in the period which are either not indicative of the underlying business performance or that impact the ability to assess the operating performance of the business. These adjustments include the amounts noted in the adjusted net earnings definition.

The company may realize similar gains or incur similar expenditures in the future.

ADJUSTED FREE CASH FLOW

Adjusted free cash flow is defined as adjusted EBITDA less capital expenditures for the period.

ADJUSTED EBITDA MARGIN

Adjusted EBITDA margin is defined as adjusted EBITDA divided by revenue for the appropriate period.

MANAGEMENT’S DISCUSSION AND ANALYSIS 43

EBITDA, adjusted EBITDA, adjusted free cash flow, and adjusted EBITDA margin are measures which allow us and other users to assess results of operations from a management perspective without regard for our capital structure. To facilitate a better understanding of these measures, the table below reconciles earnings before income taxes with EBITDA and adjusted EBITDA for the years ended 2023 and 2022.

CASH COST PER POUND, NON-CASH COST PER POUND AND TOTAL COST PER POUND FOR PRODUCED AND PURCHASED URANIUM

Cash cost per pound, non-cash cost per pound and total cost per pound for produced and purchased uranium are non-IFRS measures. We use these measures in our assessment of the performance of our uranium business. These measures are not necessarily indicative of operating profit or cash flow from operations as determined under IFRS.

¹	Direct administration and stock-based compensation are supplementary financial measures. They are components of administration expense as shown on the statement of earnings and calculated according to IFRS.

Direct administration costs in 2023 were $43 million higher than in 2022 largely due to the impacts of inflation, higher costs as a result of digital initiatives, and the restart at McArthur River/Key Lake.

We recorded $60 million in stock-based compensation expenses in 2023, $35 million higher compared to 2022 due to the increase in our share price from the comparative period. See note 25 to the financial statements.

Administration outlook for 2024

We expect direct administration costs to be between $190 million to $200 million.

EXPLORATION AND RESEARCH & DEVELOPMENT

Our 2023 exploration activities were focused primarily on Canada. Our spending increased from $11 million in 2022 to $18 million in 2023 and reflects higher planned expenditures.

We also had research and development expenditures in 2023 of $21 million compared to $12 million in 2022. These expenses are related to our investment in Global Laser Enrichment LLC (GLE). See Global Laser Enrichment on page 99.

Exploration and research & development outlook for 2024

We expect exploration expenses to be about $20 million in 2024. The focus for 2024 will be on our core projects in Saskatchewan. We expect research and development expenses to be about $37 million in 2024, primarily related to our investment in GLE. See Global Laser Enrichment on page 99.

MANAGEMENT’S DISCUSSION AND ANALYSIS 45

FINANCE COSTS

Finance costs were $116 million, an increase from $86 million in 2022 due to interest and standby fees on the facilities put in place to finance the acquisition of Westinghouse as well as higher costs related to the unwinding of the discount on our reclamation provisions. See note 20 to the financial statements.

FINANCE INCOME

Finance income was $112 million compared to $37 million in 2022 mainly due to higher interest rates and a higher short-term investments balance throughout 2023 due to the proceeds from the October 2022 share issuance that were used to partially finance the Westinghouse acquisition.

GAINS AND LOSSES ON DERIVATIVES

In 2023, we recorded $38 million in gains on our derivatives compared to $73 million in losses in 2022. The gains reflect a stronger Canadian dollar compared to the US dollar in 2023 compared to 2022. See Foreign exchange on page 49 and note 27 to the financial statements.

INCOME TAXES

We recorded an income tax expense of $126 million in 2023 compared to a recovery of $4 million in 2022 primarily as a result of higher earnings in Canada. Equity-accounted investees are included in both Canadian and foreign earnings net of tax paid in the jurisdictions in which they operate. Foreign earnings include losses in some jurisdictions for which no future tax benefit has been recognized.

In 2023, we recorded earnings of $562 million in Canada compared to earnings of $100 million in 2022, while in foreign jurisdictions, we recorded a loss of $75 million compared to a loss of $15 million in 2022.

TRANSFER PRICING DISPUTE

Background

Since 2008, Canada Revenue Agency (CRA) has disputed our marketing and trading structure and the related transfer pricing methodology we used for certain intercompany uranium sale and purchase agreements.

For the years 2003 to 2014, CRA shifted Cameco Europe Limited’s income (as recalculated by CRA) back to Canada and applied statutory tax rates, interest and instalment penalties, and, from 2007 to 2011, transfer pricing penalties. In addition, for 2014 to 2017, CRA has advanced an alternate reassessing position, see Reassessments, remittances and next steps below for more information.

In September 2018, the Tax Court of Canada (Tax Court) ruled that our 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 (2003, 2005 and 2006). On June 26, 2020, the Federal Court of Appeal (Court of Appeal) upheld the Tax Court’s decision.

46 CAMECO CORPORATION

On February 18, 2021, the Supreme Court of Canada (Supreme Court) dismissed CRA’s application for leave to appeal the June 26, 2020 decision of the Court of Appeal. The dismissal means that the dispute for the 2003, 2005 and 2006 tax years is fully and finally resolved in our favour. Although not technically binding, there is nothing in the reasoning of the lower court decisions that should result in a different outcome for the 2007 through 2014 tax years, which were reassessed on the same basis.

Refund and cost award

The Minister of National Revenue issued new reassessments for the 2003 through 2006 tax years in accordance with the decision and in July 2021, refunded the tax paid for those years. In October 2023, pursuant to a cost award from the courts, we received a payment of approximately $12 million for disbursements which is in addition to the $10 million we received from CRA in April 2021 as reimbursement for legal fees.

Reassessments, remittances and next steps

The Canadian income tax rules include provisions that generally require larger companies like us to remit or otherwise secure 50% of the cash tax plus related interest and penalties at the time of reassessment. Following the Supreme Court’s dismissal of CRA’s application for leave to appeal, we wrote to CRA requesting reversal of CRA’s transfer pricing adjustments for 2007 through 2013 and the return of the $780 million in cash and letters of credit we paid or provided for those years. Given the strength of the court decisions received, our request was made on the basis that the Tax Court would reject any attempt by CRA to defend its reassessments for the 2007 through 2013 tax years applying the same or similar positions already denied for previous years.

In March 2023, CRA issued revised reassessments for the 2007 through 2013 tax years, which resulted in a refund of $297 million of the $780 million in cash and letters of credit held by CRA at the time. The refund consisted of cash in the amount of $86 million and letters of credit in the amount of $211 million, which were returned in the second quarter. CRA continues to hold $483 million ($209 million in cash and $274 million in letters of credit) that we have remitted or secured to date.

The series of court decisions that were completely and unequivocally in our favour for the 2003, 2005 and 2006 tax years, determined that the income earned by our foreign subsidiary from the sale of non-Canadian produced uranium was not taxable in Canada. In accordance with these decisions, CRA issued reassessments reducing the proposed transfer pricing adjustment from $5.1 billion to $3.3 billion, resulting in a reduction of $1.8 billion in income taxable in Canada compared to the previous reassessments issued to us by CRA for the 2007 through 2013 tax years.

The remaining transfer pricing adjustment of $3.3 billion for the 2007 to 2013 tax years relates to the sale of Canadian-produced uranium by our foreign subsidiary. We maintain that the clear and decisive court decisions described above apply, and that CRA should fully reverse the remaining transfer pricing adjustments for these years and return all cash and security being held.

In October 2021, due to a lack of significant progress on our points of contention, we filed a notice of appeal with the Tax Court for the years 2007 through 2013. We have asked the Tax Court to order the complete reversal of CRA’s transfer pricing adjustment for those years and the return of all cash and letters of credit being held, with costs.

In 2020, CRA advanced an alternate reassessing position for the 2014 tax year in the event the basis for its original reassessment, noted above, is unsuccessful. Subsequent to this, we received a reassessment for the 2015 and 2016 tax years and in late 2023, we received a reassessment for the 2017 tax year, all reflecting this alternative reassessing position. CRA did not require additional security for the tax debts they considered owing for 2014 through 2016 but do require additional letters of credit related to the tax debts they considered owing for 2017 as discussed above, which we expect will be about $70 million.

The new basis of reassessment is inconsistent with the methodology CRA has pursued for prior years and we are disputing it separately. Our view is that this alternate methodology will not result in a materially different outcome from our 2014 to 2017 filing positions. On October 12, 2022, we filed an appeal with the Tax Court for the years 2014 and 2015, and in March 2023, filed a notice of objection for 2016. We plan to file a notice of objection for 2017.

MANAGEMENT’S DISCUSSION AND ANALYSIS 47

We will not be in a position to determine the definitive outcome of the dispute for any tax year other than 2003 through 2006 until such time as all reassessments have been issued advancing CRA’s arguments and final resolution is reached for that tax year. CRA may also advance alternative reassessment methodologies for years other than 2003 through 2006, such as the alternative reassessing position advanced for 2014 through 2017.

Caution about forward-looking information relating to our CRA tax dispute

This discussion of our expectations relating to our tax dispute with CRA and future tax reassessments by CRA is forward-looking information that is based upon the assumptions and subject to the material risks discussed under the heading Caution about forward-looking information beginning on page 2 and also on the more specific assumptions and risks listed below. Actual outcomes may vary significantly.

Assumptions

•

the courts will reach consistent decisions for subsequent tax years that are based on similar positions and arguments

•

CRA will not successfully advance different positions and arguments that may lead to a different outcome for other tax years

Material risks that could cause actual results to differ materially

•

the possibility the courts may accept the same, similar or different positions and arguments advanced by CRA to reach decisions that are adverse to us for other tax years

•

the possibility that we will not be successful in eliminating all double taxation

•

the possibility that CRA does not agree that the court decisions for the years that have been resolved in Cameco’s favour should apply to subsequent tax years

•

the possibility CRA will not return all or substantially all of the cash and security that has been paid or otherwise secured by Cameco in a timely manner, or at all

•

the possibility of a materially different outcome in disputes for other tax years

Tax outlook for 2024

Our consolidated tax rate is a blend of the statutory rates applicable to taxable income earned or tax losses incurred in Canada and in our foreign subsidiaries. Since 2017, our global marketing organization has been mainly consolidated in Canada in order to achieve efficiencies, resulting in more income earned in Canada. In addition, equity-accounted investees are included in Canadian and foreign earnings net of tax paid in the jurisdiction in which they operate. We continue to expect our consolidated tax rate will trend toward the Canadian statutory rate in the longer term.

The actual effective tax rate will vary from year-to-year, primarily due to the actual distribution of earnings among jurisdictions and differences between accounting earnings and income for tax purposes. In addition, the Organization for Economic Co-operation and Development has proposed the introduction of rules that would impose a global minimum tax rate of 15% beginning in 2024. Switzerland, Luxembourg, and Germany have all enacted or substantively enacted these rules.

FOREIGN EXCHANGE

The exchange rate between the Canadian dollar and US dollar affects the financial results of our uranium and fuel services segments.

We sell the majority of our uranium and fuel services products under long-term sales contracts, which are routinely denominated in US dollars. While our product purchases are denominated in US dollars, our production costs are largely denominated in Canadian dollars. To provide cash flow predictability, we hedge a portion of our net US/Cdn exposure (e.g. total US dollar sales less US dollar expenditures and product purchases) to manage shorter term exchange rate volatility. Our results are therefore affected by the movements in the exchange rate on our hedge portfolio, and on the unhedged portion of our net exposure.

Our risk management policy is based on a 60-month period and permits us to hedge 35% to 100% of our expected net exposure in the first 12-month period. Our normal practice is to layer in hedge contracts over a three- to four-year period with the hedge percentage being highest in the first 12 months and decreasing hedge percentages in subsequent years. The portion of our net exposure that remains unhedged is subject to prevailing market exchange rates for the period. Therefore, our results are affected by the movements in the exchange rate on our hedge portfolio (explained below), and on the unhedged portion of our net exposure. A weakening Canadian dollar would have a positive effect on the unhedged exposure, and a strengthening Canadian dollar would have a negative effect.

Impact of hedging on IFRS earnings

We do not use hedge accounting under IFRS and, therefore, we are required to report gains and losses on all hedging activity, both for contracts that close in the period and those that remain outstanding at the end of the period. For the contracts that remain outstanding, we must treat them as though they were settled at the end of the reporting period (mark-to-market).

However, we do not believe the gains and losses that we are required to report under IFRS appropriately reflect the intent of our hedging activities, so we make adjustments in calculating our ANE to better reflect the impact of our hedging program in the applicable reporting period.

Impact of hedging on ANE

We designate contracts for use in particular periods, based on our expected net exposure in that period. Hedge contracts are layered in over time based on this expected net exposure. The result is that our current hedge portfolio is made up of a number of contracts which are currently designated to net exposures we expect in 2024 and future years and we will recognize the gains or losses in ANE in those periods.

For the purposes of ANE, gains and losses on derivatives are reported based on the difference between the effective hedge rate of the contracts designated for use in the particular period and the exchange rate at the time of settlement. This results in an adjustment to current period IFRS earnings to effectively remove reported gains or losses on derivatives that arise from contracts put in place for use in future periods. The effective hedge rate will lag the market in periods of rapid currency movement. See Non-IFRS measures on page 41.

The table below provides a summary of our hedge portfolio at December 31, 2023. You can use this information to estimate the expected gains or losses on derivatives for 2024 on an ANE basis. Additionally, if we add contracts to the portfolio that are designated for use in 2024 or if there are changes in the US/Cdn exchange rates in the year, those expected gains or losses could change.

The value of the US dollar relative to the Canadian dollar was $1.00 (US) for $1.32 (Cdn), down from $1.00 (US) for $1.36 (Cdn) at December 31, 2022. The exchange rate averaged $1.00 (US) for $1.35 (Cdn) over the year.

•

The mark-to-market position on all foreign exchange contracts was a $12 million gain compared to a $48 million loss at December 31, 2022. The mark-to-market position is a component of gain on derivatives as shown on the statement of earnings and calculated in accordance with IFRS.

We manage counterparty risk associated with hedging by dealing with highly rated counterparties and limiting our exposure. At December 31, 2023, all of our hedging counterparties had a Standard & Poor’s (S&P) credit rating of A or better.

For information on the impact of foreign exchange on our intercompany balances, see note 27 to the financial statements.

Outlook for 2024

Our outlook for 2024 reflects the continued transition of our cost structure back to a tier-one run rate, as we plan our production to satisfy the growing long-term commitments under our contract portfolio. With our plan to produce 18 million pounds (100% basis) at each of Cigar Lake and McArthur River/Key Lake, and to produce 12,000 tonnes UF₆ at our Port Hope conversion facility, we expect strong financial performance, including cash flow generation.

Our financial performance and the amount of cash generated will be dependent on sourcing the material required to meet our deliveries as planned, including achieving our production plans. Therefore, our cash balances may fluctuate throughout the year.

As in prior years, we will incur care and maintenance costs for the ongoing curtailment of our tier-two assets, which are expected to be between $50 million and $60 million.

2023 outlook compared to actual

Our actual results were largely in-line with the outlook provided in our third quarter MD&A. In 2022 we announced the restart of McArthur River/Key Lake. Throughout 2023, the operations continued to ramp up production. We set a production target of 20.3 million pounds (our share) at the beginning of 2023. In September, we revised this to up to 18.7 million pounds (our share), and we achieved 17.6 million pounds (our share), consisting of 9.4 million pounds (our share) of production at McArthur River/Key Lake and 8.2 million pounds of production (our share) at Cigar Lake, both slightly below our forecast. See Uranium – Tier-one production on page 73 for more information.

At the end of the third quarter, average realized price was expected to be $65.50 per pound. This was based on a uranium spot price of $70.00 (US) per pound (the UxC spot price as of September 25, 2023) and a long-term price indicator of $61.00 (US) per pound (the UxC long-term indicator on September 25, 2023). The spot price averaged $82.21 (US) per pound during the fourth quarter, and as a result, the actual average realized price was $67.31 per pound, resulting in revenue slightly above the forecasted range for the uranium segment.

MANAGEMENT’S DISCUSSION AND ANALYSIS 51

We do not provide an outlook for the items in the table that are marked with a dash.

The following assumptions were used to prepare the outlook in the table above:

•

Production – we achieve 22.4 million pounds of production (our share) in our uranium segment. If we do not achieve 22.4 million pounds, the consolidated revenue outlook and outlook for the uranium segment could vary.

•

Market purchases – reflect the market purchases we plan to make in 2024. Market purchases may vary if planned production varies. In addition, if we decide to increase our working inventory from current levels our market purchases could be higher. Our market purchases could also be lower if, instead of making market purchases, we choose to source the required volumes by temporarily reducing inventory levels, by pulling forward long-term purchase commitments, or by drawing on loan arrangements we have in place.

•

Committed purchases – are based on the 4.7 million pounds we currently have commitments to acquire under contract in 2024 and our JV Inkai purchases, which we have assumed will be equivalent to our 2023 purchase volume of 4.2 million pounds. If Inkai production and/or deliveries vary, committed purchases may vary and we may have to rely on our other sources of supply described above. We equity account for our minority ownership interest in JV Inkai. We record our share of its production as a purchase. However, this does not reflect our share of the economic benefit. Our share of the economic benefit is based on the difference between our purchase price and JV Inkai’s lower production cost and is reflected in the line item on our statement of earnings called, “share of earnings from equity-accounted investees”. As a result, increases in the spot price increase our cost of purchases from JV Inkai and also our “share of earnings from equity-accounted investees”. The benefit is realized, through receipt of a cash dividend, when declared and paid by JV Inkai.

•

Our 2024 outlook for sales/delivery volume does not include sales between our uranium and fuel services segments.

•

Sales/delivery volume is based on the volumes we currently have commitments to deliver under contract in 2024.

•

Uranium revenue and average realized price are based on a uranium spot price of $91.00 (US) per pound (the UxC spot price on December 25, 2023), a long-term price indicator of $68.00 (US) per pound (the UxC long-term indicator on December 25, 2023) and an exchange rate of $1.00 (US) for $1.30 (Cdn)

•

Uranium average unit cost of sales (including D&A) is based on the expected unit cost of sales for produced material, the planned market purchases and committed purchases noted in the outlook at an anticipated average purchase price of about $100 (Cdn) per pound and includes care and maintenance costs of between $50 million and $60 million. We expect overall unit cost of sales could vary if there are changes in production and market or committed purchase volumes or the mix of supply sources used to meet our contract deliveries, uranium spot prices, and/or care and maintenance costs in 2023.

•

The Adjusted EBITDA outlook for Westinghouse is based on the assumptions listed in the section titled, Westinghouse – Future Prospects starting on page 94.

•

Westinghouse and JV Inkai are accounted for using the equity method for our share. Under equity accounting Westinghouse and JV Inkai capital expenditures are not presented within our consolidated financial statements and are therefore not included in our outlook for capital expenditures.

The following table shows how changes in the exchange rate or uranium prices can impact our outlook.


		IMPACT ON:
FOR 2024 ($ MILLIONS)	CHANGE	REVENUE			ANE			CASH FLOW
Uranium spot and long-term price¹	$5(US)/lb increase		9			(21	)		(49	)
Uranium spot and long-term price¹	$5(US)/lb decrease		(22	)		12			37
Value of Canadian dollar vs US dollar	One cent decrease in CAD		22			7			5
Value of Canadian dollar vs US dollar	One cent increase in CAD		(22	)		(7	)		(5	)

¹	Assuming change both UxC spot price $91.00 (US) per pound on December 25, 2023 and the UxC long-term price indicator $68.00 (US) per pound on December 25, 2023.

We have sensitivity to the uranium price through both our sales and purchase commitments. However, at the current price levels many of the market-related sales contracts we are delivering into in 2024 are subject to ceiling prices and therefore are generally less sensitive than our purchase commitments.

This sensitivity assumes that 2 million pounds of purchases are sourced from the market. To the extent that our market purchases vary, our sensitivity of ANE and cash flow to changes in the spot and long-term prices may be impacted. In the case of decreased market purchasing, our sensitivity would be reduced. In the case of increased market purchasing, our sensitivity would be greater.

Price sensitivity analysis: uranium segment

As discussed under the Long-term contracting section on page 25, our average realized price is based on pricing terms established in our portfolio of long-term contracts, which includes a mix of base-escalated and market-related contracts that are layered in over time. Each confidential contract is bilaterally negotiated with the customer and delivery generally does not begin until two years or more after signing.

•

Base-escalated contracts will reflect market conditions and pricing at the time each contract was finalized, with escalation factors applied based on when the material is delivered.

•

Market-related contracts reference a pricing mechanism that may be based on either the spot price or the long-term price, and that price is generally set a month or more prior to delivery, subject to specific terms unique to each contract, such as floors and ceilings set relative to market pricing at time of negotiation and typically escalated to time of delivery.

As a result of these contracting dynamics, changes to our average realized price will generally lag changes in market prices in both rising and falling price conditions. The magnitude and direction of the deviation can vary based on the degree of market price volatility between the time the contract price is set, and the time the product is delivered.

To help understand how the pricing under our current portfolio of commitments is expected to react at various spot prices at December 31, 2023, we have constructed the table that follows.

The table is based on the volumes and pricing terms under the long-term commitments in our contract portfolio that have been finalized as at December 31, 2023. The table does not include volumes and pricing terms in contracts under negotiation or those that have been accepted but are still subject to contract finalization. Based on the terms and volumes under contracts that have been finalized, the table is designed to indicate how our average realized price would react under various spot price assumptions at a point in time. In other words, the prices shown in the table would only be realized if the contract portfolio remained exactly as it was on December 31, 2023, using the following assumptions:

•

The uranium price remains fixed at a given spot level for each annual period shown

•

Deliveries based on commitments under finalized contracts include best estimates of the expected deliveries and flexibility under contract terms

•

To reflect escalation mechanisms contained in existing contracts, the long-term US inflation rate target of 2% is used, for modeling purposes only

It is important to note, that the table is not a forecast of prices we expect to receive. The prices we actually realize will be different from the prices shown in the table. We intend to update this table each quarter in our MD&A to reflect deliveries made and changes to our contract portfolio. As a result, we expect the table to change from quarter to quarter.

As of December 31, 2023, we had commitments requiring delivery of an average of about 27 million pounds per year from 2024 through 2028, with commitment levels in 2024 and 2025 higher than the average and in 2026 through 2028 lower than the average, reflecting our disciplined approach to contracting. As the market improves, we expect to continue to layer in volumes capturing greater upside using market-related pricing mechanisms.

MANAGEMENT’S DISCUSSION AND ANALYSIS 53

Liquidity and capital resources

Our financial objective is to ensure we have the cash and debt capacity to fund our operating activities, investments and other financial obligations in order to execute our strategy and to allow us to self-manage risk. We have a number of alternatives to fund future capital requirements, including using our operating cash flow, drawing on our existing credit facilities, entering new credit facilities, and raising additional capital through debt or equity financings. We regularly consider our financing options so we can take advantage of favourable market conditions when they arise. In addition, with improving prices under our long-term contract portfolio and the plan to return to our tier one cost structure, we expect to continue to see strong earnings and cash flow generation in 2024.

To finance our 49% share of the purchase price of Westinghouse, on November 7, 2023, we used $1.5 billion (US) of cash and drew the full amount of both $300 million (US) tranches of the term loan. See Westinghouse on page 94 for more information. At the end of 2023, we had cash and cash equivalents of $567 million, while our total debt amounted to $1.8 billion. Our cash balances and investments are held in government securities or with banks that are party to our lending facilities. We have a risk management policy that we follow to manage our exposure to banking counterparties, which limits the amount and tenor of cash or investments based on counterparty credit rating. Our investment decisions prioritize security and liquidity and consider concentration amongst our banking partners. The majority of our cash balances are with Schedule I Canadian banks.

We have large, creditworthy customers that continue to need our nuclear fuel products and services even during weak economic conditions, and we expect the contract portfolio we have built to continue to provide a solid revenue stream. In our uranium segment, from 2024 through 2028, we have commitments to deliver an average of 27 million pounds per year, with commitment levels in 2024 and 2025 higher than the average and in 2026 through 2028 lower than the average.

We expect the increased production from our tier one assets will continue to generate strong cash flows. It will allow us to source more of our committed sales from lower-cost produced pounds. However, cash flow from operations for 2024 will be dependent on our ability to source the material required to meet our deliveries as planned, including achieving our production plans.

We expect our cash balances and operating cash flows to meet our capital requirements during 2024, based on the assumption that we will refinance our $500 million debenture on or prior to its June 2024 maturity. With our expected strong cash flow generation, and in conjunction with our capital allocation priorities, we plan to reduce total debt, with a focus on the floating rate term loan. See below for more information on Investing Activities, Financing Activities and Off-Balance Sheet Arrangements and our Capital Allocation section on page 30 for more information.

With the Supreme Court’s dismissal of CRA’s application for leave, the dispute of the 2003 through 2006 tax years are fully and finally resolved in our favour. Furthermore, we are confident the courts would reject any attempt by CRA to utilize the same position and arguments for tax years 2007 through 2014, or its alternate reassessing position for tax years 2014 through 2017 and believe CRA should return all cash and letters of credit (to date, $483 million for 2007 through 2014) being held. However, timing of any further payments is uncertain, and there can be no assurance that the courts will take this position. Additionally, we expect to provide approximately $70 million in letters of credit to secure the tax debts CRA considers owing for 2017. See page 46 for more information.

CASH FROM OPERATIONS

Cash from operations in 2023 was higher than in 2022 due to higher earnings, the $86 million cash refund from CRA, higher interest received due to higher cash and investment balances, and lower working capital requirements. Purchases in 2023 were 11.3 million pounds compared to 18.3 million pounds in 2022. Not including working capital requirements, our operating cash flows in the year were up $330 million. See note 24 to the financial statements.

MANAGEMENT’S DISCUSSION AND ANALYSIS 55

INVESTING ACTIVITIES

Cash used in investing includes acquisitions and capital spending.

Capital spending

We classify capital spending as sustaining, capacity replacement or growth. As a mining company, sustaining capital is the money we spend to keep our facilities running in their present state, which would follow a gradually decreasing production curve, while capacity replacement capital is spent to maintain current production levels at those operations. Growth capital is money we invest to generate incremental production, and for business development. We have a capital allocation process to approve our capital spend. See Capital Allocation beginning on page 30 for more information.

Our 2024, 2025 and 2026 capital spending estimates assume that we produce 18 million pounds (100% basis) per year at McArthur River/Key Lake and at Cigar Lake and produce 12,000 tonnes per year at our UF₆ conversion facility. If our production plans change, then our capital spending estimates may change.

Our estimate for capital spending in 2024 has been increased to between $215 million and $250 million (previously between $150 million and $200 million) due to the capital required to meet production targets sustainably and reliably, commencement of work on the Cigar Lake extension and the rescheduling of some expenditures planned in 2023 to 2024.

Our estimate for capital spending in 2025 has been increased to between $200 million and $250 million (previously between $100 million and $150 million) due to the rescheduling of expenditures and work on the Cigar Lake extension.

Capital expenditures for JV Inkai are expected to be covered by JV Inkai cash flows in 2024 and Westinghouse capital expenditures are expected to be covered by Westinghouse cash flows, both are included in our overall equity investment.

Major capital expenditures in 2024 include:

•

Investments required to refresh aging infrastructure to help ensure reliable and sustainable production at all our operations as planned

•

Fuel services – continued work on our Vision in Motion project

•

Cigar Lake – begin work on the Cigar Lake extension. See Cigar Lake starting on page 77.

This information regarding currently expected capital expenditures for future periods is forward-looking information and is based upon the assumptions and subject to the material risks discussed on pages 4 to 6. Our actual capital expenditures for future periods may be significantly different.

FINANCING ACTIVITIES

Cash from financing includes borrowing and repaying debt, and other financial transactions including paying dividends and providing financial assurance.

¹	Debt and interest on debt is calculated assuming that all debt is held to maturity and as such does not incorporate the expected reduction in 2024 of the term loan outstanding, or any other reductions, and the associated impact on interest payments.

We have contractual capital commitments of approximately $61 million at December 31, 2023. Certain of the contractual commitments may contain cancellation clauses; however, we disclose the commitments based on management’s intent to fulfil the contracts.

We have sufficient borrowing capacity with available unsecured lines of credit totalling about $2.7 billion, which include the following:

•

A $1.0 billion unsecured revolving credit facility that matures October 1, 2027. Each calendar year, upon mutual agreement, the facility can be extended for an additional year. We may increase the revolving credit facility above $1.0 billion, by increments of no less than $50 million, up to a total of $1.25 billion. The facility ranks equally with all of our other senior debt. At December 31, 2023, there were no amounts outstanding under this facility.

•

Financial assurance facilities with various financial institutions and insurers of approximately $1.7 billion. At December 31, 2023, we had approximately $1.4 billion outstanding on these facilities. We use these facilities mainly to provide financial assurance for future decommissioning and reclamation of our operating sites, for our obligations relating to the CRA dispute, and as overdraft protection.

In total we have $1.0 billion in senior unsecured debentures outstanding:

•

$500 million bearing interest at 4.19% per year, maturing on June 24, 2024 (classified as current)

•

$400 million bearing interest at 2.95% per year, maturing on October 21, 2027

•

$100 million bearing interest at 5.09% per year, maturing on November 14, 2042

Additionally, we have approximately $800 million in term loan debt. We have drawn the full amount of the single advance

$600 million (US) term loan that was put in place concurrently with the execution of the Westinghouse acquisition agreement, of which $300 million (US) matures in November 2025 and $300 million (US) matures in November 2026. We have initiated a partial repayment of $200 million (US) on the $300 million (US) tranche which matures in November 2026. The term loan facility requires interest rate elections on each tranche, priced at the applicable rate of:

•

Term Secured Overnight Financing Rate (SOFR) plus a credit spread adjustment of 0.10% and a margin that currently ranges from 1.7% to 1.95%, or

•

US base rate, plus a margin that currently ranges from 0.7% to 0.95%

The margins are dependent on the company’s credit rating and as such could change over the term if the credit rating changes.

MANAGEMENT’S DISCUSSION AND ANALYSIS 57

The $280 million (US) bridge commitment that we also secured concurrently with the acquisition agreement was not required to complete the transaction and was terminated.

Debt covenants

Our credit agreements include the following financial covenants:

•

our funded debt to tangible net worth ratio must be 1:1 or less

•

other customary covenants and events of default

Funded debt is total consolidated debt less non-recourse debt, $100 million in letters of credit, cash and cash equivalents and short-term investments.

Not complying with any of these covenants could result in accelerated payment and termination of our credit agreements. At December 31, 2023, we complied with all covenants, and we expect to continue to comply in 2024.

OFF-BALANCE SHEET ARRANGEMENTS

We had three kinds of off-balance sheet arrangements at the end of 2023:

•

purchase commitments

•

financial assurances

•

other arrangements

Purchase commitments

We make purchases under long-term contracts where it is beneficial for us to do so and to support our long-term contract portfolio. The following table is based on our purchase commitments in our uranium and fuel services segments at December 31, 2023², but does not include purchases of our share of Inkai production. These commitments include a mix of fixed-price and market-related contracts. Actual payments will be different as a result of changes to our purchase commitments and, in the case of contracts with market-related pricing, the market prices in effect at the time of delivery. We will update this table as required in our MD&A to reflect material changes to our purchase commitments and changes in the prices used to estimate our commitments under market-related contracts.

²	These amounts have been adjusted for any additional purchase commitments that we have entered into since December 31, 2023, but does not include deliveries taken under contract since December 31, 2023.

We have commitments of $529 million (Cdn) for the following:

•

approximately 8.4 million pounds of U₃O₈ equivalent from 2024 to 2028

•

approximately 0.3 million kgU as UF₆ in conversion services in 2024

•

about 0.4 million Separative Work Units (SWU) of enrichment services to meet existing forward sales commitments under agreements with a non-Western supplier

The suppliers do not have the right to terminate agreements other than pursuant to customary events of default provisions.

Financial assurances

We use standby letters of credit and surety bonds mainly to provide financial assurance for the decommissioning and reclamation of our mining and conversion facilities.

Once we have permanently stopped mining and processing activities at an operating site, we are required to decommission the site to the satisfaction of the regulators. We have developed preliminary decommissioning plans for our operating sites and use them to estimate our decommissioning costs. Regulators review and accept our preliminary decommissioning plans on a regular basis. As the site approaches or goes into decommissioning, regulators review the detailed decommissioning plans. This can result in further regulatory process, as well as additional requirements, costs and financial assurances.

58 CAMECO CORPORATION

We have submitted updates to all Saskatchewan operations’ Preliminary Decommissioning Plan (PDP) and Preliminary Decommissioning Cost Estimate (PDCE) documents in accordance with the five-year timeline specified in the regulations. Upon acceptance of the PDP and PDCE documents by the Saskatchewan Ministry of Environment and Canadian Nuclear Safety Commission (CNSC) staff, a formal Commission proceeding will be required for final approval of the PDP and PDCE by the Commission. All Saskatchewan mining operations have received the necessary approvals for the current PDP and PDCE and all required financial assurances are in place.

The PDP and PDCE for the Blind River refinery were revised in 2020. The CNSC approved the PDCE in February 2022 and the financial assurance was updated in March 2022. The Cameco Fuel Manufacturing PDP and PDCE were revised in 2021, and the revised PDCE was approved by the Commission in February 2022 and the financial assurance was updated in March 2022. The PDP and PDCE for the Port Hope conversion facility were revised in 2022 and submitted to CNSC staff in September 2022 and are currently under review by CNSC staff. A decision on the PDCE is expected by the Commission in April 2024, after which the financial assurance will be updated.

For Smith Ranch-Highland, the 2023 surety was approved and the credit instruments are being reviewed by the State of Wyoming. For Crow Butte, the 2023 annual update was submitted to the federal Nuclear Regulatory Commission and Nebraska Department of Environmental Quality in September 2023.

At the end of 2023, our estimate of total decommissioning and reclamation costs was $1.36 billion. This is the undiscounted value of the obligation and is based on our current operations. We had accounting provisions of $1.05 billion at the end of 2023 (the present value of the $1.36 billion). Regulatory approval is required prior to beginning decommissioning. The expected timing for these costs in based on each mine or fuel service facility’s expected operating life. Our required costs for decommissioning and reclamation in each of the next five years are not expected to be material. However, we may choose to undertake progressive reclamation activities, for example, as we do at our US assets and through our Vision in Motion project at our Port Hope fuel services facilities.

We had a total of about $1.06 billion in financial assurances supporting our reclamation liabilities at the end of 2023. All of our North American operations have financial assurances in place in connection with our preliminary plans for decommissioning of the sites.

We are also providing letters of credit until the CRA dispute is resolved.

Our financial assurances renew automatically on an annual basis, unless otherwise advised by the issuing institution. At December 31, 2023 our financial assurances totaled $1.4 billion, down from $1.6 billion at December 31, 2022, largely due to the return of letters of credit in the amount of $211 million from CRA. See Transfer pricing dispute on page 46.

Other arrangements

We have arranged for standby product loan facilities with various counterparties. The arrangements allow us to borrow up to 2.0 million kgU of UF₆ conversion services and 3.5 million pounds of U₃O₈ over the period 2020 to 2026 with repayment in kind up to December 31, 2026. Under the loan facilities, standby fees of up to 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 2.0%. At December 31, 2023, we have 1.8 million kgU of UF₆ conversion services and 2.8 million pounds of U₃O₈ drawn on the loans.

Total product inventories increased by 4% to $692 million this year due to the higher cost of purchased material. At December 31, 2023, our average cost for uranium was $49.62 per pound, up from $43.45 per pound at December 31, 2022. As of December 31, 2023, we held an inventory of 10.3 million pounds of U₃O₈ equivalent (excluding broken ore).

MANAGEMENT’S DISCUSSION AND ANALYSIS 59

At the end of 2023, our total assets amounted to $9.9 billion, an increase of 15% compared to 2022, due mainly to the addition of Westinghouse as an equity-accounted investee, partially offset by the decrease in cash and cash equivalents and short-term investments used to fund the acquisition. In 2022, the total asset balance increased by $1.1 billion compared to 2021, due mainly to an increase in investment balances resulting from the October 2022 issuance of common shares in preparation for the closing of the Westinghouse transaction as well as higher inventories.

Production volumes in 2023 increased by 69% compared to 2022. See Uranium – production overview on page 72 for more information.

Uranium revenues this year were up 45% compared to 2022 due to an increase in sales volumes of 25% and an increase of 16% in the Canadian dollar average realized price due to the impact of the increase in average US dollar spot price on market-related contracts as well as the weakening of the Canadian dollar. For more information on the impact of spot price changes on average realized price, see Price sensitivity analysis: uranium segment on page 53.

Total cost of sales (including D&A) increased by 26% ($1.71 billion compared to $1.36 billion in 2022) due primarily to an increase in sales volume of 25% as well as a 1% increase in unit cost of sales. Unit cost of sales is slightly higher than in the same period in 2022 due to the higher cost of purchased material in 2023 compared to the same period in 2022 mostly offset by higher operational readiness costs at McArthur River/Key Lake operations in 2022.

The net effect was a $323 million increase in gross profit for the year.

The following table shows the costs of produced and purchased uranium incurred in the reporting periods (see Non-IFRS measures starting on page 41). These costs do not include care and maintenance costs, operational readiness costs, selling costs such as royalties, transportation and commissions, nor do they reflect the impact of opening inventories on our reported cost of sales.

Due to equity accounting for JV Inkai, our share of production is shown as a purchase at the time of delivery. JV Inkai purchases will fluctuate during the quarters and timing of purchases will not match production. In 2023 we purchased 4.2 million pounds at a purchase price per pound of $92.72 ($67.69 (US)) (2022 – 3.3 million pounds at a purchase price per pound of $62.78 ($47.33 (US))).

MANAGEMENT’S DISCUSSION AND ANALYSIS 61

The average cash cost of production was 25% higher compared to 2022, due to lower production at Cigar Lake in 2023 as well as well as inflationary pressures and the ongoing ramp up of production at McArthur/Key Lake.

In 2024, we expect the average unit cost of production at McArthur River/Key Lake to continue to be higher than the average unit life of mine operating costs reflected in our most recent annual information form as we complete the ramp up of production and continue work to realize the benefits from the operational improvements that have been made. The average unit production cost at Cigar Lake is expected to trend down with higher planned production. The estimated average unit life of mine operating costs reflected in our most recent annual information form are $16 per pound at McArthur River/Key Lake and $18 per pound at Cigar Lake.

We equity account for our share of JV Inkai. As a result, we record our share of its production as a purchase, which under Kazakhstan’s pricing regulations, requires we purchase the material at a price equal to the uranium spot price, less a 5% discount. However, this does not reflect the economic benefit to Cameco. Our share of the economic benefit is based on the difference between our purchase price and JV Inkai’s lower production cost and is reflected in the line item on our statement of earnings called, “share of earnings from equity-accounted investees.” This benefit is realized through receipt of a cash dividend, when declared and paid by JV Inkai. Excess cash, net of working capital requirements is distributed to the partners as dividends. If there is a significant disruption to JV Inkai’s operations for any reason, it may not achieve its production plans, there may be a delay in production, and it may experience increased costs to produce uranium.

Our purchases in 2023, totaled about $916 million, representing an average annual cost of $81.02 per pound, about $45.00 per pound higher than our total unit production cost for the year. Although purchased pounds are transacted in US dollars, we account for the purchases in Canadian dollars. The average cost of purchased material in Canadian dollar terms increased by 58% this year compared to 2022. The average cash cost of purchased material was $81.02 (Cdn), or $59.42 (US) per pound, compared to $51.36 (Cdn), or $39.45 (US) per pound in the same period in 2022.

ROYALTIES

We pay royalties on the sale of all uranium extracted at our mines in the province of Saskatchewan. Two types of royalties are paid:

•

Basic royalty: calculated as 5% of gross sales of uranium, less the Saskatchewan resource credit of 0.75%.

•

Profit royalty: a 10% royalty is charged on profit up to and including $28.182/kg U₃O₈ ($12.78/lb) and a 15% royalty is charged on profit in excess of $28.182/kg U₃O₈. Profit is determined as revenue less certain operating, exploration, reclamation and capital costs. Both exploration and capital costs are deductible at the discretion of the producer.

As a resource corporation in Saskatchewan, we also pay a corporate resource surcharge of 3% of the value of resource sales.

Total cost of products and services sold (including D&A) increased 21% ($301 million compared to $248 million in 2022), due to the 8% increase in sales volume as well as a 13% increase in average unit cost of sales compared to 2022 due to higher input costs.

The net effect was a $7 million increase in gross profit.

Westinghouse

OUR 2023 EARNINGS FROM WESTINGHOUSE

On November 7, 2023, we announced the closing of the acquisition of Westinghouse in a strategic partnership with Brookfield. Cameco now owns a 49% interest and Brookfield owns the remaining 51%. Under the equity method of accounting, beginning on November 7, 2023, we have included our share of Westinghouse’s earnings in our financial results.

Key things to note:

•

The timing of customer requirements, which tends to vary from quarter to quarter, drives revenue in the uranium and fuel services segments, meaning quarterly results are not necessarily a good indication of annual results due to the variability in customer requirements.

•

Net earnings do not trend directly with revenue due to unusual items and transactions that occur from time to time. We use adjusted net earnings, a non-IFRS measure, as a more meaningful way to compare our results from period to period (see page 41 for more information).

•

Cash from operations tends to fluctuate as a result of the timing of deliveries and product purchases in our uranium and fuel services segments.

Production volumes this quarter increased by 54% compared to the fourth quarter of 2022. See Uranium – production overview on page 72 for more information.

Uranium revenues were up 76% due to a 42% increase in sales volume due to the timing of sales, which were in line with the delivery pattern disclosed in our 2022 annual MD&A, and a 24% increase in the Canadian dollar average realized price. While the average US dollar spot price for uranium increased by 65% compared to the same period in 2022, the Canadian dollar average realized price increased by 24% due to the timing of market changes on our contract portfolio. For more information on the impact of spot price changes on average realized price, see Price sensitivity analysis: uranium segment on page 53.

Total cost of sales (including D&A) increased by 62% ($605 million compared to $373 million in 2022). This was primarily the result of the 42% increase in sales volume as well as an increase of 14% in the average unit cost of sales which was due to the higher cost of purchased material.

The net effect was a $72 million increase in gross profit for the quarter.

Due to equity accounting for JV Inkai, our share of production will be shown as a purchase at the time of delivery. JV Inkai purchases will fluctuate during the quarters and timing of purchases will not match production. During the quarter we purchased 2.8 million pounds at a purchase price per pound of $105.74 ($77.13 (US)) (Q4 2022 – 2.6 million pounds at a purchase price per pound of $61.27 ($45.60 (US))).

MANAGEMENT’S DISCUSSION AND ANALYSIS 67

The average cash cost of production for the fourth quarter was 8% higher compared to the same period in the prior year. Cash cost was higher due to the effect of supply chain challenges and inflationary pressures.

Although purchased pounds are transacted in US dollars, we account for the purchases in Canadian dollars. In the fourth quarter, the average cash cost of purchased material was $89.89 (Cdn) per pound, or $65.67 (US) per pound in US dollar terms, compared to $57.02 (Cdn) per pound, or $42.18 (US) per pound in the fourth quarter of 2022.

MANAGEMENT’S DISCUSSION AND ANALYSIS 71

Uranium – production overview

Our share of production in our uranium segment in the fourth quarter was 5.7 million pounds, 54% higher compared to the same period in 2022, while production for the year was 17.6 million pounds, 69% higher than in 2022. In 2022, there was no production from McArthur River and Key Lake until the fourth quarter. Total production in 2023 was 1.1 million pounds below the revised production plan we announced in September.

The Rabbit Lake operation remained in a safe and sustainable state of care and maintenance, and we are no longer developing new wellfields at Crow Butte and Smith Ranch-Highland. See Uranium – Tier-one operations starting on page 73 and Uranium – Tier-two operations beginning on page 85 for more information.

PRODUCTION OUTLOOK

We remain focused on taking advantage of the long-term growth we see coming in our industry, while maintaining the ability to respond to market conditions as they evolve. Our strategy includes a focus, in our uranium segment, on protecting and extending the value of our contract portfolio, on aligning our production decisions with our contract portfolio and market opportunities in order to increase long-term value, and to do that with an emphasis on safety, people and the environment.

In 2024, we are planning production of 22.4 million pounds (our share).

Due to equity accounting, our share of production from Inkai is shown as a purchase. Based on KAP’s announcement on February 1, 2024, production in Kazakhstan is expected to remain 20% below the level stipulated in subsoil use agreements, similar to in 2023, primarily due to the sulfuric acid shortage in the country. We are still in discussions with JV Inkai and KAP to determine how this may impact production at Inkai in 2024 and thereafter and therefore our corresponding purchase obligation. We expect to purchase the remaining share of our 2023 production entitlement, which has arrived at a Canadian port.

MANAGEMENT’S DISCUSSION AND ANALYSIS 73

BACKGROUND

Mine description

The mineral reserves at McArthur River are contained within seven zones: zones 1, 2, 3, 4, 4 South, A and B. There are currently two active mining zones (zone 2 and 4), one with development significantly advanced (zone 1), and one in the early stages of development (zone 4 South).

Zone 2 has been actively mined since production began in 1999. The ore zone was initially divided into three freeze panels. As the freeze wall was expanded, the inner connecting freeze walls were decommissioned to recover the inaccessible uranium around the active freeze pipes. Mining of zone 2 is almost complete. About 3.5 million pounds of mineral reserves remain, and we expect to recover them using a combination of raisebore and blasthole stope mining.

Zone 4 has been actively mined since 2010. The zone was divided into four freeze panels, and like in zone 2, as the freeze wall was expanded, the inner connecting freeze walls were decommissioned. Zone 4 has 103.9 million pounds of mineral reserves secured behind freeze walls, and it will be the main source of production for the next several years. Raisebore and blasthole stope mining will be used to recover the mineral reserves.

Zone 1 is the next planned mine area to be brought into production. Freeze hole drilling was completed in 2023 and brine distribution construction work has resumed. A small section of the planned freeze wall is currently actively freezing. Once brine distribution construction is complete and an active freeze wall has been established, drill and extraction chamber development will need to be completed prior to the start of production. Once complete, an additional 48.0 million pounds of mineral reserves will be secured behind freeze walls. Blasthole stope mining is currently planned as the main extraction method in zone 1.

Zone 4 South is in the early development stages. Access development for the freeze drifts has resumed on the lower levels and freeze drilling began at the end of 2023 on the upper freeze drifts which were established prior to the 2018 shutdown.

We have successfully extracted over 340 million pounds (100% basis) since we began mining in 1999.

Mining methods and techniques

All the mineralized areas discovered to date at McArthur River are in, or partially in, water-bearing ground with significant pressure at mining depths.

There are three approved mining methods at McArthur River: raisebore mining, blasthole stope mining and boxhole mining. However, only raisebore and blasthole stope mining remain in use. Before we begin mining an area, we freeze the ground around it by circulating chilled brine through freeze holes to form an impermeable frozen barrier.

Blasthole stope mining

Blasthole stope mining began in 2011 and is the main extraction method planned for future production. It is planned in areas where blastholes can be accurately drilled and small stable stopes excavated without jeopardizing the freeze wall integrity. The use of this method has allowed the site to improve operating costs by increasing overall extraction efficiency by reducing underground development, concrete consumption, mineralized waste generation and improving extraction cycle time.

Raisebore mining

Raisebore mining is an innovative non-entry approach that we adapted to meet the unique challenges at McArthur River, and it has been used since mining began in 1999. This method is favourable for mining the weaker rock mass areas of the deposit and is suitable for massive high-grade zones where there is access both above and below the ore zone.

Initial processing

McArthur River produces two product streams, high grade slurry and low-grade mineralized rock. Both product streams are shipped to Key Lake mill to produce uranium ore concentrate.

The high-grade material is ground and thickened into a slurry underground and then pumped to surface. The material is then thickened and blended for grade control and shipped to Key Lake in slurry totes using haul trucks.

The low-grade mineralized material is hoisted to surface and shipped as a dry product to Key Lake using covered haul trucks. Once at Key Lake, the material is ground, thickened and blended with the high-grade slurry to a nominal 5% U₃O₈ mill feed grade. It is then processed into uranium ore concentrate and packaged in drums for further processing offsite.

74 CAMECO CORPORATION

Tailings capacity

Based on the current licence conditions, tailings capacity at Key Lake is sufficient to mill all the known McArthur River mineral reserves and resources, should they be converted to reserves, with additional capacity to toll mill ore from other regional deposits.

Licensed annual production capacity

The McArthur River mine and Key Lake mill are both licensed to produce up to 25 million pounds (100% basis) per year. To achieve annual production at the licensed capacity, additional investment will be required.

2023 UPDATE

Production

The McArthur River and Key Lake operation was in a state of safe care and maintenance from 2018 through 2021 due to weak market conditions. The operation began transitioning back to production through the first three quarters of 2022, with no packaged pounds until the fourth quarter of 2022. Production ramp-up activities continued in 2023.

Total packaged production from McArthur River and Key Lake in 2023 was 13.5 million pounds (9.4 million pounds our share), slightly less than the announced September 3, 2023, forecast of 14 million pounds (9.8 million pounds our share).

The McArthur River mine continued to operate well and achieved its planned mine production for the year. Any ore from McArthur River that was not immediately processed at Key Lake is stored in inventory for future milling. All required mine activities have now resumed at McArthur and the site is now considered to be back in normal mine operations.

At the Key Lake mill, the extended period of time the mill was on care and maintenance, the operational changes made, aging infrastructure, the availability of personnel with the necessary skills and experience, and the impact of supply chain challenges on the availability of materials and reagents combined to impact production in 2023.

Licensing

In October 2023, the Canadian Nuclear Safety Commission (CNSC) granted 20-year renewals to the licences for both McArthur River and Key Lake. The renewed licences are expected to allow McArthur River and Key Lake to operate until October 2043.

Exploration

Underground exploration at McArthur River resumed in June 2023 with the resumption of infill drilling of zone B. Infill drilling of zone B will continue in 2024.

PLANNING FOR THE FUTURE

Production

We plan to produce 18 million pounds (100% basis) in 2024. Over the last three months, the mill has been running at a rate that, when annualized, would allow this operation to achieve its 2024 planned production. In 2024, we plan to undertake an evaluation of the work and investment necessary to expand production up to its annual licensed capacity, which we expect will allow us to take advantage of this opportunity when the time is right. We will continue to plan our production to align with our contract portfolio and market opportunities, demonstrating that we continue to be a responsible supplier of uranium fuel.

MANAGING OUR RISKS

The McArthur River deposit presents unique challenges that are not typical of traditional hard or soft rock mines. These challenges are the result of mining in or near high pressure ground water in challenging ground conditions with significant radiation concerns due to the high-grade uranium. We take significant steps and precautions to reduce the risks. Mine designs and mining methods are selected based on their ability to mitigate hydrological, radiological and geotechnical risks. Operational experience gained since the start of production has resulted in a significant reduction in risk. However, there is no guarantee that our efforts to mitigate risk will be successful.

MANAGEMENT’S DISCUSSION AND ANALYSIS 75

In addition to the risks listed on pages 70 to 71, in 2024 we are focused on the management of the following risks:

Mine and mill ramp up

With the extended period of time the assets were on care and maintenance, the operational changes made, aging infrastructure, and commissioning issues that we have worked through at the mill, which caused delays to the production schedule in 2022 and 2023, there is continued uncertainty regarding the timing of a successful ramp up to planned 2024 production and the associated costs. In addition, inflation, the availability of personnel with the necessary skills and experience, and the potential impact of supply chain challenges on the availability of materials and reagents carry with them the risks of not achieving our production plans, production delays and increased costs.

Labour relations

The collective agreement with the United Steelworkers local 8914 expired in December 2022, and we are in negotiations to reach a new agreement. As in the past, work continues under the terms of the expired collective agreement while negotiations proceed. There is a risk to the production plan if we are unable to reach an agreement and there is a labour disruption.

Water inflow risk

All the mineralized areas discovered to date at McArthur River are in, or partially in, water-bearing ground with significant pressure at mining depths. This high-pressure water source is isolated from active development and production areas to reduce the inherent risk of an inflow. McArthur River relies on pressure grouting and ground freezing, and sufficient pumping, water treatment and above ground storage capacity to mitigate the risks of the high-pressure ground water.

McArthur River has not experienced a significant disruption to its mining or development activities resulting from a water inflow since 2008. The consequences of another water inflow at McArthur River would depend on its magnitude, location and timing, but could include a significant interruption or reduction in production, a material increase in costs or a loss of mineral reserves.

BACKGROUND

Mine description

Cigar Lake’s geological setting is similar to McArthur River’s. However, unlike McArthur River, the Cigar Lake deposit is horizontally oriented.

Mine development is carried out in the basement rocks below the ore horizon. New mine development is required throughout the mine life to gain access to the ore above.

Mining method

At Cigar Lake, the permeable sandstone which overlays the deposit and basement rocks, contains large volumes of water at significant pressure. Before we begin mining, we freeze the ore zone and surrounding ground. We use a jet boring system to mine the ore.

MANAGEMENT’S DISCUSSION AND ANALYSIS 77

Jet boring system (JBS) mining

As a result of the unique geological conditions at Cigar Lake, we are unable to utilize traditional mining methods that require access above the ore, which necessitated the development of a non-entry mining method specifically adapted for this deposit. After many years of test mining, we selected jet boring, and it has been used since mining began in 2014. This method involves:

•

drilling a pilot hole into the frozen orebody, inserting a high pressure water jet and cutting a cavity out of the frozen ore

•

collecting the ore and water mixture (slurry) from the cavity and pumping it to a storage sump, allowing it to settle

•

using a clamshell, transporting the ore from the storage sump to an underground grinding and processing circuit

•

once mining is complete, filling each cavity in the orebody with concrete

•

starting the process again with the next cavity.

We have divided the orebody into production panels and at least three production panels need to be frozen at one time to achieve the annual production rate. One JBS machine is located below each frozen panel. Three JBS machines are currently in operation. Two machines actively mine at any given time while the third is moving, setting up, or undergoing maintenance.

We have successfully extracted approximately 138.4 million pounds (100% basis) since we began mining in 2014.

Initial processing

We carry out initial processing of the extracted ore at Cigar Lake before shipping it to McClean Lake. To accomplish this, we:

•

grind the ore and mix it with water to form a slurry in our underground circuit

•

pump the slurry 500 metres to the surface and store it in one of two ore slurry holding tanks, where it is blended and thickened to remove excess water

•

the final slurry, at an average grade of approximately 17% U₃O₈, is pumped into transport truck containers and shipped to McClean Lake mill on a 69-kilometre all-weather road

Water from this process, including water from underground operations, is treated on the surface. Any excess treated water is released into the environment.

Milling

All of Cigar Lake’s ore slurry is being processed at the McClean Lake mill, operated by Orano. Given the McClean Lake mill’s capacity, it is able to:

•

process up to 18 million pounds U₃O₈ per year

•

process and package all of Cigar Lake’s current mineral reserves

Licensing annual production capacity

The Cigar Lake mine is licensed to produce up to 18 million pounds (100% basis) per year. Orano’s McClean Lake mill is licensed to produce 24 million pounds annually.

2023 UPDATE

Production

Total packaged production from Cigar Lake in 2023 was 15.1 million pounds U₃O₈ (8.2 million pounds our share) compared to 18.0 million pounds U₃O₈ (9.8 million pounds our share) in 2022.

Productivity was impacted as we completed development and commissioning activities in the first quarter and achieved first production from a new mining area. We had expected to recover from these delays in the second half of the year. However, in the third quarter, we determined maintenance work was required on one of the underground circuits, which had not been planned. The additional time required to complete this work did not allow for the delayed production volumes to be recovered prior to year-end.

During the year, we:

•

executed planned 21-day annual maintenance activities in September

•

executed production activities from four production tunnels in the eastern part of the orebody and one, for the first time, from the western part of the orebody

78 CAMECO CORPORATION

•

in alignment with our long-term production planning, brought two new panels online

•

continued underground header construction activities and expanded our ground freezing program to ensure continued frozen ore inventory

•

completed our freeze hole drilling program in the second quarter

Underground development

Underground mine development continued in 2023. We completed our second production crosscut in the western portion of the orebody in preparation for ore mining starting in the second quarter of 2024.

PLANNING FOR THE FUTURE

Production

In 2024, we expect to produce 18 million pounds (100% basis) at Cigar Lake; our share is approximately 9.8 million pounds.

In 2024, we plan to:

CIGAR LAKE EXTENSION

Completion of a prefeasibility study of the indicated resources contained in the Cigar Lake extension orebody (referred to as Phase 2 in the technical report filed in 2016), demonstrated the economic feasibility of extracting those resources, allowing us to convert 73.4 million pounds (100% basis) (40 million pounds our share), to probable reserves and extending the estimated mine life to 2036. Based on our analyses, we expect our share of the up-front capital cost to complete the mine development and other capacity replacement projects necessary to access these reserves to be between $250 million and $300 million. We expect the average life of mine unit cash operating costs for Cigar Lake production to increase to between $19 per pound and $20 per pound (previously $18.13 per pound) and our share of annual production to be between 9.5 million pounds and 10.0 million pounds.

A new NI 43-101 technical report for Cigar Lake is in the process of being finalized and is expected to be filed under Cameco’s profile on SEDAR+ within 45 days of this release. More detailed descriptions of the scientific and technical information on which the mineral reserves and mine plan are based will be included in the relevant sections of the technical report. Once filed, the new technical report will supersede and replace the current technical report titled “Cigar Lake Operation, Northern Saskatchewan, Canada” dated March 29, 2016, with an effective date of December 31, 2015. A copy is available on SEDAR+ (www.sedarplus.com), on EDGAR (www.sec.gov/edgar.shtml), and on Cameco’s website (www.cameco.com/media/media-library).

MANAGING OUR RISKS

The Cigar Lake deposit presents unique challenges that are not typical of traditional hard or soft rock mines. These challenges are the result of mining in or near high-pressure ground water in challenging ground conditions with significant radiation concerns due to the high-grade uranium and elements of concern in the orebody with respect to water quality. We take significant steps and precautions to reduce the risks. Mine designs and the mining method are selected based on their ability to mitigate hydrological, radiological, and geotechnical risks. Operational experience gained since the start of production has resulted in a significant reduction in risk. However, there is no guarantee that our efforts to mitigate risk will be successful.

In addition to the risks listed on pages 70 to 71, in 2023 we are focused on the management of the following risks:

Inflation, labour shortages, and supply chain challenges

Inflation, the availability of personnel with the necessary skills and experience, and the impact of supply chain challenges on the availability of materials and reagents carry with them the risk of not achieving our production plans, production delays and increased costs in 2024 and future years.

MANAGEMENT’S DISCUSSION AND ANALYSIS 79

Transition to new mining areas

In order to successfully achieve the planned production schedule, we must continue to successfully transition into new mining areas, which includes mine development and investment in critical support infrastructure, and deployment of the jet boring method in new areas. If development or infrastructure construction work is delayed for any reason, including availability of storage capacity for waste rock, or if the performance of our jet boring method is materially different than previously mined areas, our ability to meet our future production plans may be impacted.

Water inflow risk

The sandstone that overlays the Cigar Lake deposit and basement rocks is water-bearing with significant pressure at mining depths. This high-pressure water source is isolated from active development and production areas in order to reduce the inherent risk of an inflow. Cigar Lake relies on ground freezing and sufficient pumping, water treatment and above ground storage capacity to mitigate the risks of the high-pressure ground water.

Cigar Lake has not experienced a significant disruption resulting from a water inflow since 2008. The consequences of another water inflow at Cigar Lake would depend on its magnitude, location and timing, but could include a significant interruption or reduction in production, a material increase in costs or a loss of mineral reserves.

MANAGEMENT’S DISCUSSION AND ANALYSIS 81

BACKGROUND

Mine description

The Inkai uranium deposit is a roll-front type orebody within permeable sandstones. The more porous and permeable units host several stacked and relatively continuous, sinuous “roll-fronts” of low-grade uranium forming a regional system. Superimposed over this regional system are several uranium projects and active mines.

Inkai’s mineralization ranges in depths from about 260 metres to 530 metres. The deposit has a surface projection of about 40 kilometres in length, and the width ranges from 40 to 1600 metres. The deposit has hydrogeological and mineralization conditions favourable for use of in situ recovery (ISR) technology.

Mining and milling method

JV Inkai uses conventional, well-established, and very efficient ISR technology, developed after extensive test work and operational experience. The process involves five major steps:

•

leach the uranium in situ by circulating an acid-based solution through the host formation

•

recover it from solution with ion exchange resin (takes place at both main and satellite processing plants)

•

precipitate the uranium with hydrogen peroxide

•

thicken, dewater, and dry it

•

package the uranium peroxide product in drums

Production

Through our investment in Inkai, production continued to be impacted by the 20% supply reduction enacted by KAP across all uranium mines in Kazakhstan and the continued supply chain challenges it has faced. KAP has the ability to flex production 20% above or below planned production levels (8.3 million to 12.5 million pounds per year). Total 2023 production from Inkai was 8.3 million pounds (100% basis), the same as in 2022. In 2023, Inkai experienced a number of operational issues related to interruptions in reagent delivery and wellfield drilling.

The first shipment, containing approximately two thirds of our share of Inkai’s 2023 production, arrived in the fourth quarter. The second shipment with the remainder of our share of 2023 production has arrived at a Canadian port. We continue to work closely with JV Inkai and our joint venture partner, KAP, to receive our share of production via the Trans-Caspian International Transport Route, which does not rely on Russian rail lines or ports.

Production purchase entitlements

Under the terms of a restructuring agreement signed with our partner KAP in 2016, our ownership interest in JV Inkai is 40% and KAP’s share is 60%. However, during production ramp-up to the licensed limit of 10.4 million pounds, we are entitled to purchase 57.5% of the first 5.2 million pounds of annual production, and as annual production increases over 5.2 million pounds, we are entitled to purchase 22.5% of such incremental production, to the maximum annual share of 4.2 million pounds. Once the ramp-up to 10.4 million pounds annually is complete, we will be entitled to purchase 40% of such annual production, matching our ownership interest.

Based on an adjustment to the production purchase entitlement under the 2016 JV Inkai restructuring agreement, for 2023 we were entitled to purchase 4.2 million pounds, or 50% of JV Inkai’s planned 2023 production of 8.3 million pounds. Timing of our JV Inkai purchases will fluctuate during the quarters and may not match production, and, in particular, in 2023, timing was impacted by shipping delays. Total purchases in 2023 were 4.2 million pounds, of which 2.8 million pounds were related to our 2023 entitlement.

Cash distribution

Excess cash, net of working capital requirements, will be distributed to the partners as dividends. In 2023, we received a cash dividend from JV Inkai of $79 million (US), net of withholdings. Our share of dividends follows our production purchase entitlements as described above.

PLANNING FOR THE FUTURE

Production

Based on KAP’s announcement on February 1, 2024, production in Kazakhstan is expected to remain 20% below the level stipulated in subsoil use agreements, similar to in 2023, primarily due to the sulfuric acid shortage in the country. We are still in discussions with JV Inkai and KAP to determine how this may impact production at Inkai in 2024 and thereafter and therefore our corresponding purchase obligation.

Our share of production is purchased at a discount to the spot price and included at this value in inventory. In addition, JV Inkai capital is not included in our outlook for capital expenditures.

MANAGING OUR RISKS

In addition to the risks listed on pages 70 to 71, JV Inkai also manages the following risks:

Production forecast

Presently, JV Inkai is experiencing procurement and supply chain issues, most notably, related to the availability of sulfuric acid. It is also experiencing challenges related to construction delays and inflationary pressures on its production costs. Production plans for 2024 and subsequent years are uncertain and being reassessed. A significant disruption to JV Inkai’s previous production plans for 2024 and subsequent years could result in penalties and further escalation of production costs. In addition, JV Inkai’s costs could be impacted by potential changes to the tax code in Kazakhstan and by possible increased financial contributions to social and other state causes, although these risks cannot be quantified or estimated at this time.

Depending on production levels at Inkai and the outcome of our discussions related thereto with JV Inkai and KAP, our share of production and earnings from this equity-accounted investee and the amount and timing of our dividends from the joint venture may be impacted.

Transportation

The geopolitical situation continues to cause transportation risks in the region. We could continue to experience delays in our expected Inkai deliveries from 2023 and for 2024. To mitigate this risk, we have inventory, long-term purchase agreements and loan arrangements in place we can draw on. Depending on when we receive shipments of our share of Inkai’s production, our share of earnings from this equity-accounted investee and the timing of the receipt of our share of dividends from the joint venture may be impacted.

MANAGEMENT’S DISCUSSION AND ANALYSIS 83

Political

Kazakhstan declared itself independent in 1991 after the dissolution of the Soviet Union. Our investment in JV Inkai is subject to the greater risks associated with doing business in developing countries, which have significant potential for social, economic, political, legal and fiscal instability. Kazakhstan laws and regulations are complex and still developing and their application can be difficult to predict. The other owner of JV Inkai is Kazatomprom, an entity majority owned by the government of Kazakhstan. We have entered into agreements with JV Inkai and Kazatomprom intended to mitigate political risk. This risk includes the imposition of governmental laws or policies that could restrict or hinder JV Inkai paying us dividends, or selling us our share of JV Inkai production, or that impose discriminatory taxes or currency controls on these transactions. The restructuring of JV Inkai, which took effect January 1, 2018, was undertaken with the objective to better align the interests of Cameco and Kazatomprom and includes a governance framework that provides for protection for us as a minority owner of JV Inkai.

For more details on this risk, please see our most recent annual information form under the heading political risks.

JV Inkai manages risks listed on pages 70 to 71.

PLANNING FOR THE FUTURE

2024 Planned activity

No work is planned at Millennium, Yeelirrie or Kintyre in 2024.

MANAGEMENT’S DISCUSSION AND ANALYSIS 87

MANAGING THE RISKS

Project approval

The approval received for Kintyre from the prior state government required substantial commencement of the project by March 2020, being within five years of the grant of the approval, and this was not achieved. The current government declined to grant us an extension to achieve it. In the future, we can apply for an extension of time to achieve substantial commencement of the project. If granted by a future government we could commence the Kintyre project, provided we have all other required regulatory approvals.

The approval for the Yeelirrie project, received from the prior state government, required substantial commencement of the project by January 2022, and this was not achieved. The current government declined to grant us an extension to achieve it. In the future, we can again apply for an extension of time to achieve substantial commencement of the project. If granted by a future government we could commence the Yeelirrie project, provided we have all other required regulatory approvals. Approval for the Yeelirrie project at the federal level was granted in 2019 and extends until 2043.

For all of our advanced projects, we manage the risks listed on pages 70 to 71.

Uranium – exploration

Our exploration program is focused on replacing mineral reserves as they are depleted by our production, which is key to sustaining our business, meeting our commitments, and ensuring long-term growth. Our global exploration activity is adjusted annually in line with market signals and at a pace aligned with Cameco’s mining plans and sourcing needs. In recent years, we have increased exploration spending in response to the significant, positive momentum in the nuclear fuel market that has provided a clear signal that more uranium production will be required in the next decade, setting the stage for a renewed exploration cycle.

Our position as one of the world’s largest uranium producers and our continued growth across the nuclear fuel cycle has been driven by decades of experience and our history of exploration, discovery and mining success. Our land position totals 740,000 hectares (1.8 million acres) that cover exploration and development prospects in Canada, Australia, Kazakhstan and the US that are among the best in the world. In northern Saskatchewan alone, we have direct interests in 650,000 hectares (1.6 million acres) that cover many of the most prospective areas of the prolific Athabasca Basin.

In northern Saskatchewan, our well-established infrastructure includes fully licensed and fully permitted uranium mills and mines in the eastern Athabasca basin, along with a supporting network of roads, airstrips and electricity supply. That infrastructure provides us with an advantage that not only underpins the potential development of our advanced exploration projects, but also supports our ongoing work to both delineate existing prospects and deposits, and to identify future undiscovered uranium potential of the region. Additionally, our decades of work to establish a positive corporate reputation by prioritizing our relationships with northern Saskatchewan Indigenous communities, confirms our long-term commitment to continually engage and provide ongoing benefits to the people that call the region home.

The uranium endowment of the Athabasca Basin, where we are involved in 39 projects (including partner-operated joint ventures), is well known and combined with the basin’s unique geological history, it creates a remarkable mining jurisdiction hosting the highest uranium grades and some of the largest uranium deposits in the world. On our projects, we have identified numerous uranium occurrences, prospects, and undeveloped deposits of variable grades and sizes that have progressed through multiple stages of evaluation. Depending on the potential deposit size, ore and ground quality, evolving mining technologies and the uranium market environment, some of these prospects are expected to become viable, economic deposits in a uranium market and price environment that supports new primary production and provides an adequate risk-adjusted return.

LOGO

MANAGEMENT’S DISCUSSION AND ANALYSIS 89

The combination of our large land position and proven expertise in discovering and developing world class uranium mines provides the foundation for future mill-supported exploration projects, ranging from early to advanced stages of greenfield exploration and for brownfield opportunities to extend the lives of our existing operations.

LOGO

2023 UPDATE

Brownfield and advanced exploration

Brownfield and advanced exploration activities include exploration near our existing operations and expenses for maintaining advanced projects and delineation drilling where uranium mineralization is being defined. In 2023, we spent about $4.5 million in Saskatchewan, $1 million in Australia and $1 million in the US on brownfields and advanced exploration projects. The spending in Saskatchewan was primarily focused on advancing the extension of the mine life at Cigar Lake and advanced exploration on the Dawn Lake project.

The Dawn Lake project is located approximately 45 km northwest of the Rabbit Lake operation, on the La Rocque Lake corridor which hosts several historic discoveries and deposits. In 2023, exploration drilling at Dawn Lake expanded the footprint of known uranium mineralization with mineralized intercepts in excess of 60% U₃O₈ over several metres. Although the deposit remains at a very early stage of exploration, the high-grade results and geological conditions observed to date are comparable to those of other mines and known deposits in the Athabasca Basin, generating interest and a focused effort to better understand its potential.

Regional exploration

Regional exploration is defined as projects that are considered greenfield. In 2023, we spent about $11 million on regional exploration programs that are comprised of target generation geophysical surveys and diamond drilling primarily in northern Saskatchewan.

PLANNING FOR THE FUTURE

We plan to continue to focus on our core projects in Saskatchewan under our long-term exploration framework. Our leadership position and industry expertise in both exploration and corporate social responsibility makes us a partner of choice and for properties and projects that meet our investment criteria, we may partner with other companies through strategic alliances, equity holdings and traditional joint venture arrangements to optimize our exploration activity and spending.

Brownfields and Advanced Exploration

In 2024, we plan to spend about $7 million on brownfields and advanced Exploration, primarily to expand the footprint of the mineralization identified on in the La Rocque Lake corridor of the Dawn Lake project.

Regional Exploration

We plan to spend about $13 million on diamond drilling and target generation geophysical surveys on our core regional projects in Saskatchewan, in 2024.

Port Hope conversion facility cleanup and modernization (Vision in Motion)

Vision in Motion is a unique opportunity that demonstrates our continued commitment to a clean environment. It has been made possible by the opening of a long-term waste management facility by the Government of Canada’s Port Hope Area Initiative project. There is a limited opportunity during the life of this project to engage in clean-up and renewal activities that address legacy waste at the Port Hope Conversion facility inherited from historic operations. Good progress was made over the past year with the removal of old buildings and structures on site, and the project will continue to be active in the year ahead.

PLANNING FOR THE FUTURE

Production

We plan to produce between 13.5 million and 14.5 million kgU in 2024. This includes increasing annual production at our Port Hope UF₆ conversion facility to 12,000 tonnes to satisfy our book of long-term business and demand for conversion services.

Licensing

In January 2023, the CNSC granted a 20-year renewal to the licence for CFM. The licence renewal also grants CFM’s request for a slight production increase to 1,650 tonnes as UO₂ fuel pellets.

MANAGING OUR RISKS

We take significant steps and precautions to reduce risk. However, there is no guarantee that our efforts to mitigate risk will be successful.

In addition to the risks listed on pages 70 to 71, in 2024 we are focused on the management of the following risk:

Production plans

Inflation, the availability of personnel with the necessary skills and experience, aging infrastructure, and the potential impact of supply chain challenges on the availability of materials and reagents carry the risk of not achieving our production plans, production delays, and increased costs in 2024 and future years.

Labour relations

The collective agreement with unionized employees at our fuel manufacturing operations in Port Hope and Cobourg expires in June 2024. During past negotiations, work has continued under the terms of the expired collective agreement while negotiations to reach a new agreement proceeded. There is a risk to the production plan if we are unable to reach an agreement and there is a labour dispute.

MANAGEMENT’S DISCUSSION AND ANALYSIS 93

Westinghouse Electric Company

Westinghouse is a nuclear reactor technology original equipment manufacturer (OEM) and a leading provider of highly technical aftermarket products and services to commercial nuclear power utilities and government agencies globally. Westinghouse’s history in the energy industry stretches back over a century, during which time the company became a pioneer in nuclear energy.

•

It is the OEM or a technology provider to about 50% of the global nuclear reactor fleet, delivering capacity of about 190,000 carbon-free MWe.

•

It has three fuel fabrication facilities, one in the US, one in Sweden and one in the United Kingdom.

•

In addition, it has about 90 facilities, engineering centers, and workshops, with a presence in more than 20 countries.

The company has strong recurring and predictable revenue and cash flow profiles due to the critical and non-discretionary nature of its products and services to the operation of nuclear power plants around the world.

Like Cameco, Westinghouse enables carbon-free baseload and dispatchable energy that is needed to support the energy transition and we believe is therefore well-positioned for long-term growth.

Bringing together Cameco’s expertise in the nuclear industry with Brookfield’s expertise in clean energy positions nuclear power at the heart of the energy transition and creates a powerful platform for strategic growth across the nuclear sector.

The total enterprise value at time of close was $7.9 billion (US) and was adjusted for working capital balances at that time, resulting in a final enterprise value of $8.2 billion (US). At time of close, Westinghouse had $3.8 billion (US) in outstanding debt commitments, for which it maintains responsibility, and which reduced the equity cost of the acquisition.

To finance Cameco’s 49% share of the purchase price, equaling $2.1 billion (US), we used $1.5 billion (US) of cash and drew the full amount of both $300 million (US) tranches of the term loan put in place concurrently with the execution of the acquisition agreement, and which mature two years and three years from the date of close. The $280 million (US) bridge commitment that we also secured concurrently with the acquisition agreement was not required to complete the transaction and was terminated.

The acquisition of Westinghouse was completed in the form of a limited partnership with Brookfield. The board of directors governing the limited partnership consists of six directors, three appointed by Cameco and three appointed by Brookfield. Decision-making by the board corresponds to percentage ownership interests in the limited partnership (51% Brookfield and 49% Cameco). However, decisions with respect to certain reserved matters under the partnership agreement, such as the approval of the annual budget, require the presence and support of both Cameco and Brookfield appointees to the board as long as certain ownership thresholds are met.

We believe Westinghouse is well-positioned for long-term growth driven by the expected increase in global demand for nuclear power. As of November 7, 2023, we receive the economic benefit of our ownership in Westinghouse. We account for our proportionate interest in Westinghouse on an equity basis.

94 CAMECO CORPORATION

We expect this strategic acquisition will be transformative and accretive to Cameco. We are enhancing our ability to compete for more business by investing in additional nuclear fuel cycle assets that we expect will augment the core of our business and offer more solutions to our customers across the nuclear fuel cycle. Like Cameco, Westinghouse has nuclear assets that are strategic, proven, licensed and permitted, and that are in geopolitically attractive jurisdictions. We expect these assets, like ours, will participate in the growing demand profile for nuclear energy.

Cash distributions

Annually, we and Brookfield (the partners) approve a budget and business plan which outline Westinghouse’s financial projections and capital allocation priorities. The determination of whether to make cash distributions to the partners will be reviewed quarterly based on the approved budgeted expenditures and capital allocation priorities, including growth investment opportunities, as well as available cash balances. However, the timing of cash distributions is expected to be aligned with the timing of Westinghouse’s cash flows, which are typically higher in the fourth quarter.

Westinghouse debt

As at December 31, 2023, Westinghouse had the following outstanding debt:

•

$3.5 billion (US) term loan with a maturity of August 2025

•

credit facilities of $400 million (US), which had drawings of $115 million (US) and mature in June 2026

•

drawn financial assurances including letters of credit of $474 million (US) and surety bonds of $262 million (US)

Effective January 25, 2024, Westinghouse refinanced its existing debt and entered into various credit agreements which now provide total borrowing capacity of $4.6 billion (US), comprised of:

•

$3.5 billion (US) term loan which now matures on January 25, 2031, and has quarterly repayments of $8.75 million (US), with any remaining amounts due at maturity. The term loan is priced at the applicable term SOFR rate plus a margin that is currently 2.75%.

•

credit facilities totaling $500 million (US), which mature in January 2029

•

financial assurances including letters of credit in the amount of about $570 million (US) and surety bonds of $262 million (US)

The credit agreements are non-recourse to Cameco, but come with certain covenants, which if breached, could result in all amounts outstanding thereunder to be immediately due and payable by Westinghouse. We expect Westinghouse to continue to comply with these covenants in 2024.

WESTINGHOUSE NON-IFRS MEASURES

EBITDA, adjusted EBITDA and adjusted free cash flow and adjusted EBITDA margin are supplemental measures which are used by us and other users, including our lenders and investors, to assess the results of operations for Westinghouse from a management perspective without regard to its capital structure. We believe that these measures are useful to management, lenders and investors in assessing the underlying performance of Westinghouse’s ongoing operations and its ability to generate cash flows to fund its cash requirements. See Non-IFRS measures starting on page 41.

The financial information in the table below is provided to allow comparison to, and is in line with the outlook provided in our November 7, 2023, news release. It is derived from the consolidated financial statements of Westinghouse, which are reported in US dollars and prepared in accordance with US GAAP, and does not reflect Cameco’s ownership share.

FUTURE PROSPECTS

Amid the ongoing demand growth and global energy security concerns, we expect there will be new opportunities for Westinghouse to compete for and win new business. Westinghouse’s reputation as a global leader in the nuclear industry and its position as the only fully European supplier for certified VVER fuel assemblies are expected to benefit its core business as Eastern European countries seek to develop a reliable fuel supply chain independent of Russia.

In addition to growth in its core business, the focus on the importance of nuclear power in providing carbon-free, secure and affordable baseload power as an essential part of the electricity grid in many countries is creating new opportunities for Westinghouse’s proven AP1000 reactor design, as well as the smaller reactor designs it has in development. Its technology and experience provide a competitive advantage as the engineering and procurement aspects of new build programs are initiated.

The following financial outlook is reported in Canadian dollars and prepared in accordance with IFRS and reflects Cameco’s 49% ownership share.

In 2024, we expect our share of Adjusted EBITDA from our equity investment in Westinghouse to be between $445 million and $510 million. Over the next five years, we expect its Adjusted EBITDA will grow at a compound annual growth rate of 6% to 10%. Adjusted EBITDA is a non-IFRS measure (see Non-IFRS Measures starting on page 41).

The outlook for Adjusted EBITDA for 2024 and its growth over the next five years are based on the following assumptions:

•

An exchange rate of $1.00 (US) for $1.30 (Cdn)

96 CAMECO CORPORATION

•

Growth from new AP1000 reactor projects is based on agreements that have been signed and announcements where the AP1000 technology has been selected, including Poland, Bulgaria and Ukraine. It is assumed that work on announced agreements and announced selections to be done by Westinghouse would proceed on the timelines and revenue pattern noted under the New Build Framework. The growth only assumes Westinghouse undertakes the Engineering and Procurement work required prior to a new reactor project breaking ground, which is a small component of the overall potential. A delay in project timelines or cancellation of announced projects would result in a growth rate near the bottom of the range.

•

It is also expected that investments in new technologies, including eVinci^™ microreactor and AP300^™ small modular reactor, will be made in accordance with the current business plan and are expected to contribute to Adjusted EBITDA largely outside the 5-year time frame.

New Build

New Build framework

Westinghouse undertakes its role in the design, development, engineering and procurement of equipment for new reactors. It does not provide construction services or assume any construction risk. This segment has the potential to add significant long-term value during the construction phase, and then to the core of the business through reactor services and fuel supply contracts once the reactor begins commercial operation.

Following an announcement of a successful bid, there are a number of contracts that must be signed before work commences and revenue is realized. The chart below is an illustrative framework and the assumptions used for the expected timing of revenue flows and profitability as these large, one-time decisions by utilities to construct new nuclear power plants using Westinghouse’s proven AP1000 reactor design are made.

Assumptions and estimates:

•

Cost to construct new AP1000 reactor in the US based on an MIT (Massachusetts Institute of Technology) study: $6 billion to $8 billion (US), although it can vary significantly depending on in-country labour and construction productivity rates. There is a measured and noticeable scale effect where multiple reactors have been built – for example, in China, where four AP1000 reactors are in operation and six more are under construction, and the US, where two were built and one is in operation.

•

Engineering and procurement work: 25% to 40% of total plant cost, depending on the scope of the project – excluding China, where Westinghouse scope is typically less than 10% of the total project cost.

•

EBITDA margin for new build activity is expected to be aligned with the overall core business, although it can vary between 10% to 20%.

MANAGEMENT’S DISCUSSION AND ANALYSIS 97

Illustrative framework of Westinghouse revenue flow for reactor new build project

LOGO

Other growth opportunities

In addition to its AP1000 reactor design, Westinghouse has submitted its pre-application Regulatory Engagement Plan with the US Nuclear Regulatory Commission for the development of its AP300 small modular reactor, which is based on the proven and licensed AP1000 reactor design. Its eVinci microreactor design was recently awarded US Department of Energy funding for a test reactor FEED (front-end engineering design) at Idaho National Lab. The AP300 small modular reactor and the eVinci microreactor are expected to offer the same carbon-free baseload benefits as larger nuclear reactor technologies, but are tailored for specific applications, including industrial, remote mining, off-grid communities, defense facilities and critical infrastructure. As with the AP1000 reactor, they are expected to have applications beyond electricity generation, including district and process heat, desalination and hydrogen production. We are optimistic about the future competitiveness of these technologies and their potential to make a meaningful contribution to Westinghouse’s long-term financial performance. However, they are presently still in the development phase.

Caution about forward-looking information relating to Westinghouse

This discussion of our expectations relating to the future prospects of Westinghouse is subject to the assumptions and risks that are discussed under the heading Caution about forward-looking information beginning on page 2 and may be subject to the risks listed under the heading Managing the risks, starting on page 70, which include:

Assumptions

•

the market conditions and other factors upon which we have based Westinghouse’s future plans and forecasts

•

Westinghouse’s ability to mitigate adverse consequences of delays in production and construction, and the success of its plans and strategies

•

the absence of new and adverse government regulations, policies or decisions, and that Westinghouse will comply with nuclear licence and quality assurance requirements at its facilities

•

Material risks that could cause actual results to differ materially

•

the risk that Westinghouse may not be able to meet sales commitments for any reason

•

the risk that Westinghouse may not achieve the expected growth or success in its business

•

the risk that Westinghouse’s strategies may change, be unsuccessful, or have unanticipated consequences

Global Laser Enrichment

Global Laser Enrichment LLC (GLE) is the exclusive worldwide licensee of the proprietary Separation of Isotopes by Laser EXcitation (SILEX) laser uranium enrichment technology, a third-generation enrichment technology. Cameco is the commercial lead for the GLE project with a 49% interest and we hold an option to attain a majority interest of 75%. Silex Systems Ltd. (Silex Systems) owns the other 51% interest in GLE and is the licensor of the SILEX laser enrichment technology and the technology lead for GLE.

Subject to completion of the technology demonstration program and its progression through to commercialization, GLE has the potential to offer a variety of advantages to the global nuclear energy sector, including:

•

re-enriching depleted uranium tails leftover as a by-product of first-generation gaseous diffusion enrichment operation, repurposing legacy waste into a commercial source of uranium and conversion products to fuel nuclear reactors and aiding in the responsible clean-up of legacy tails inventories, as per GLE’s agreement with the US Department of Energy (DOE);

•

producing commercial low-enriched uranium (LEU) to fuel the world’s existing and future fleet of large-scale light-water reactors (and depending on market developments, SMR’s that also require LEU-based fuel) with greater efficiency and flexibility than current enrichment technologies; and

•

producing high-assay low-enriched uranium (HALEU), if a market for that fuel stock develops to serve a number of small modular reactor (SMR) and advanced reactor designs that might be commercially deployed and require HALEU-based fuel.

Our view is that re-enriching US government inventories of depleted uranium tails into a commercial source of uranium and conversion is GLE’s lowest-risk path to the market. This opportunity is underpinned by an agreement GLE has with the DOE to upgrade depleted uranium tails leftover from DOE’s historic enrichment operations, which may help address the growing supply gap for Western nuclear fuel supplies and services.

With the support of both Cameco and Silex Systems, GLE has accelerated its technology demonstration project activities to target an earlier delivery of the successful demonstration of Technology Readiness Level 6 (TRL-6). TRL-6 achievement will confirm large-scale system performance under relevant conditions (pilot-scale demonstration), which represents a major step up in a technology’s demonstrated readiness. Of note, GLE received the second full-scale laser system module from Silex Systems last year, which was installed in GLE’s pilot demonstration facility in the US. GLE’s efforts to bring forward planned activities and expenditures under the technology demonstration program are intended to demonstrate TRL-6 this year. Earlier TRL-6 demonstration may provide optionality for GLE to pursue government and industry support and funding related to potential commercial deployment opportunities (LEU and, potentially, HALEU) that could precede tails re-enrichment if the right conditions exist.

Unless another commercial deployment opportunity materializes, GLE will continue its work to complete the technology demonstration project with the potential to deploy its enrichment technology at a commercial scale in Western Kentucky under its agreement with the DOE no later than 2030. GLE’s path to commercialization depends on several factors, including but not limited to the successful progression and completion of GLE’s technology demonstration and maturation program, a clear commercial use case, sound market fundamentals, clarity regarding future Russian fuel imports, the ability to secure substantial government support and funding (specifically, accelerated commercial pathways related to LEU and, potentially, HALEU are reliant on government funding) and long-term industry support.

MANAGING OUR RISKS

GLE is subject to the risks relating to the nuclear industry discussed under the heading Caution about forward-looking information beginning on page 2.

MANAGEMENT’S DISCUSSION AND ANALYSIS 99

Mineral reserves and resources

Our mineral reserves and resources are the foundation of our company and fundamental to our success.

We have interests in a number of uranium properties. The tables in this section show the estimates of the proven and probable mineral reserves, and measured, indicated, and inferred mineral resources at those properties. However, only three of the properties listed in those tables are material uranium properties for us: McArthur River/Key Lake, Cigar Lake and Inkai. Mineral reserves and resources are all reported as of December 31, 2023.

We estimate and disclose mineral reserves and resources in five categories, using the definition standards adopted by the Canadian Institute of Mining, Metallurgy and Petroleum Council, and in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (NI 43-101), developed by the Canadian Securities Administrators. You can find out more about these categories at www.cim.org.

About mineral resources

Mineral resources do not have to demonstrate economic viability but have reasonable prospects for eventual economic extraction. They fall into three categories: measured, indicated and inferred. Our reported mineral resources are exclusive of mineral reserves.

•

measured and indicated mineral resources can be estimated with sufficient confidence to allow the appropriate application of technical, economic, marketing, legal, environmental, social and governmental factors to support evaluation of the economic viability of the deposit

•

measured resources: we can confirm both geological and grade continuity to support detailed mine planning

•

indicated resources: we can reasonably assume geological and grade continuity to support mine planning

•

inferred mineral resources are estimated using limited geological evidence and sampling information. We do not have enough confidence to evaluate their economic viability in a meaningful way. You should not assume that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource, but it is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration.

Our share of uranium in the following mineral resource tables is based on our respective ownership interests. Reported mineral resources have not demonstrated economic viability.

About mineral reserves

Mineral reserves are the economically mineable part of measured and/or indicated mineral resources demonstrated by at least a preliminary feasibility study. The reference point at which mineral reserves are defined is the point where the ore is delivered to the processing plant, except for ISR operations where the reference point is where the mineralization occurs under the existing or planned wellfield patterns. Mineral reserves fall into two categories:

•

proven reserves: the economically mineable part of a measured resource for which at least a preliminary feasibility study demonstrates that, at the time of reporting, economic extraction could be reasonably justified with a high degree of confidence

•

probable reserves: the economically mineable part of a measured and/or indicated resource for which at least a preliminary feasibility study demonstrates that, at the time of reporting, economic extraction could be reasonably justified with a degree of confidence lower than that applying to proven reserves

For properties where we are the operator, we use current geological models, an average uranium price of $54 (US) per pound U₃O₈, and current or projected operating costs and mine plans to report our mineral reserves, allowing for dilution and mining losses. We apply our standard data verification process for every estimate. For properties in which we have an interest but are not the operator, we will take reasonable steps to ensure that the reserve and resource estimates that we report are reliable.

100 CAMECO CORPORATION

Our share of uranium in the mineral reserves table below is based on our respective ownership interests.

LOGO

Changes this year

Our share of proven and probable mineral reserves increased from 469 million pounds U₃O₈ at the end of 2022, to 485 million pounds at the end of 2023. The change was primarily the result of:

•

mineral resource estimate update at Cigar Lake Extension and subsequent conversion of indicated mineral resources adding 40 million pounds to probable reserves.

partially offset by:

•

production at Cigar Lake, Inkai and McArthur River, which removed 22 million pounds of proven and probable reserves from our mineral inventory

The remaining changes are attributable to other adjustments based on the mineral resource and reserve estimate updates at Cigar Lake, McArthur River and Inkai.

Our share of measured and indicated mineral resources decreased from 451 million pounds U₃O₈ at the end of 2022, to 409 million pounds at the end of 2023. Our share of inferred mineral resources decreased from 154 million pounds U₃O₈ to 153 million pounds.

Important information about mineral reserve and resource estimates

Although we have carefully prepared and verified the mineral reserve and resource figures in this document, the figures are estimates, based in part on forward-looking information.

Estimates are based on knowledge, mining experience, analysis of drilling results, the quality of available data and management’s best judgment. They are, however, imprecise by nature, may change over time, and include many variables and assumptions, including:

•

geological interpretation

•

extraction plans

•

commodity prices and currency exchange rates

•

recovery rates

•

operating and capital costs

There is no assurance that the indicated levels of uranium will be produced, and we may have to re-estimate our mineral reserves based on actual production experience. Changes in the price of uranium, production costs or recovery rates could make it unprofitable for us to operate or develop a particular site or sites for a period of time. See page 2 for information about forward-looking information.

Please see our mineral reserves and resources section of our most recent annual information form for the specific assumptions, parameters and methods used for McArthur River, Inkai and Cigar Lake mineral reserve and resource estimates.

Important information for US investors

We present information about mineralization, mineral reserves and resources as required by National Instrument 43-101 – Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators (NI 43-101), in accordance with applicable Canadian securities laws. As a foreign private issuer filing reports with the US Securities and Exchange Commission (SEC) under the Multijurisdictional Disclosure System, we are not required to comply with the SEC’s disclosure requirements relating to mining properties. Investors in the United States should be aware that the disclosure requirements of NI 43-101 are different from those under applicable SEC rules, and the information that we present concerning mineralization, mineral reserves and resources may not be comparable to information made public by companies that comply with the SEC’s reporting and disclosure requirements for mining companies.

In our uranium and fuel services segments, we are required to estimate the cost of decommissioning and reclamation for each operation, but we normally do not incur these costs until an asset is nearing the end of its useful life. Regulatory requirements and decommissioning methods could change during that time, making our actual costs different from our estimates. A significant change in these costs or in our mineral reserves could have a material impact on our net earnings and financial position. See note 16 to the financial statements.

Carrying value of assets

We depreciate property, plant and equipment primarily using the unit-of-production method, where the carrying value is reduced as resources are depleted. A change in our mineral reserves would change our depreciation expenses, and such a change could have a material impact on amounts charged to earnings.

We assess the carrying values of property, plant and equipment, intangibles and investments in associates and joint ventures every year, or more often if necessary. If we determine that we cannot recover the carrying value of an asset, we write off the unrecoverable amount against current earnings. We base our assessment of recoverability on assumptions and judgments we make about future prices, production costs, our requirements for sustaining capital, our ability to economically recover mineral reserves and the impact of geopolitical events. A material change in any of these assumptions could have a significant impact on the potential impairment of these assets.

Taxes

When we are preparing our financial statements, we estimate taxes in each jurisdiction we operate in, taking into consideration different tax rates, non-deductible expenses, valuation of deferred tax assets, changes in tax laws and our expectations for future results.

We base our estimates of deferred income taxes on temporary differences between the assets and liabilities we report in our financial statements, and the assets and liabilities determined by the tax laws in the various countries we operate in. We record deferred income taxes in our financial statements based on our estimated future cash flows, which includes estimates of non-deductible expenses, future market conditions, production levels and intercompany sales. If these estimates are not accurate, there could be a material impact on our net earnings and financial position.

Controls and procedures

We have evaluated the effectiveness of our disclosure controls and procedures and internal control over financial reporting as of December 31, 2023, as required by the rules of the US Securities and Exchange Commission and the Canadian Securities Administrators.

MANAGEMENT’S DISCUSSION AND ANALYSIS 105

Management, including our Chief Executive Officer (CEO) and our Chief Financial Officer (CFO), supervised and participated in the evaluation, and concluded that our disclosure controls and procedures are effective to provide a reasonable level of assurance that the information we are required to disclose in reports we file or submit under securities laws is recorded, processed, summarized and reported accurately, and within the time periods specified. It should be noted that, while the CEO and CFO believe that our disclosure controls and procedures provide a reasonable level of assurance that they are effective, they do not expect the disclosure controls and procedures or internal control over financial reporting to be capable of preventing all errors and fraud. A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

Management, including our CEO and our CFO, is responsible for establishing and maintaining internal control over financial reporting and conducted an evaluation of the effectiveness of our internal control over financial reporting based on the Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2023.

There have been no changes in our internal control over financial reporting during the year that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

New standards adopted

A number of amendments to existing standards became effective January 1, 2023, but they did not have an effect on our financial statements.

A number of amendments to existing standards are not yet effective for the year ended December 31, 2023, and have not been applied in preparing these consolidated financial statements. We do not intend to early adopt any of the amendments and do not expect them to have a material impact on our financial statements.
