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 below.
• 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 below.
• 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 below. 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.

NET EARNINGS

The following table shows what contributed to the change in net earnings and adjusted net earnings (non-IFRS measure, see below) in the three months and year ended December 31, 2023, compared to the same period in 2022.

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).

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.

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.

For the year ended December 31, 2023:

For the year ended December 31, 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.

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.
