“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 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.”

Financial Highlights

Summary of 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.
• 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.
