Cameco Announces 2025 Results; Solid Fourth Quarter and 2025 Performance; Increasing Long-Term Uranium Market Activity Reinforces Constructive Outlook; Disciplined Supply Strategy Expected to Position Company to Unlock Value From Growing Demand

SASKATOON, Saskatchewan–(BUSINESS WIRE)–$CCJ #cameco–Cameco (TSX: CCO; NYSE: CCJ) today reported its consolidated financial and operating results for the fourth quarter and year ended December 31, 2025, in accordance with International Financial Reporting Standards (IFRS).

“Our fourth quarter and year-end results reflect another year of disciplined execution across our uranium, fuel services, and Westinghouse segments, demonstrating the strength of our strategy in a market that continues to evolve in support of long‑term value creation,” said Tim Gitzel, Cameco’s CEO. “We delivered solid performance with strong contributions from our core assets and improved financial results tied to our disciplined long-term supply strategy in a constructive demand environment. As anticipated, our fourth‑quarter results were strengthened by robust contributions from all segments of our business, supporting a strong finish to the year. This outcome highlights our continued ability to navigate market developments with a measured, deliberate approach that aligns with our long‑term objectives.

“Across the nuclear industry, 2025 marked another year of accelerating global momentum. We saw renewed commitments to nuclear energy from governments, utilities, and industrial energy users around the world, including policies that continued to reinforce nuclear’s critical role in delivering secure, reliable and carbon-free baseload power. That support was accompanied by increasing long‑term contracting activity towards the end of the year, with a deepening focus on security of supply, and rising interest from existing and emerging nuclear markets, including traditional utilities and new industrial energy users that are considering nuclear. Utilities continue to seek dependable supply in an environment where finite secondary supplies are thinning, and it is becoming more obvious each day that potential new production is expected to be challenged by longer-than-advertised lead times, mounting inflationary pressures and geopolitical uncertainty. The underlying message is clear to us: the fundamentals that have been steadily improving over the past several years gained further traction in 2025, and we expect these trends to continue through 2026 and beyond.

“In this environment, our disciplined approach to supply in our uranium and fuel services segments remains a cornerstone of our strategy. We continued to align our production with our long‑term contract portfolio, maintaining a deliberate and conservative approach which, based on our decades of experience, we believe to be the prudent position. Combined with our strong balance sheet, and about 230 million pounds of uranium committed under long‑term contracts, we believe we are well positioned to unlock value in a strengthening market. We do not manage the business to satisfy short‑term themes in the market, nor do we chase volume for volume’s sake, or plan to bring forward uncommitted supply that risks recreating the overhangs that historically disrupted contracting cycles. Instead, we remain focused on protecting and extending the value of our tier‑one assets and investments, leveraging our integrated capabilities, and preserving the flexibility that allows us to respond to opportunities as the market continues its transition.

“Additionally, the value‑accretive contributions from our Westinghouse investment continue to outperform the acquisition case expectations. The segment continued to positively impact our overall results in 2025, including a 30% increase in adjusted EBITDA over 2024, reflecting strong underlying performance across its core businesses. We also benefited from a cash distribution from Westinghouse of US$350 million, with US$171.5 million representing our share, tied to its participation in the Dukovany nuclear project. While we don’t expect a comparable additional distribution this year, the 2026 guidance for Westinghouse remains strong and reinforces the value of our investment, highlighting Westinghouse’s role as a stable, long‑term player within a strengthening global nuclear market.

“Looking forward, we believe we will continue to see a durable trend of growth across the nuclear fuel cycle supported by electrification, energy security and decarbonization priorities, and the increasing recognition that nuclear must play a central role in addressing the world’s long‑term energy challenges. Cameco is well positioned to benefit from this global shift, driving long‑term value for our shareholders, our customers, and the communities where we operate.”

• Consolidated performance: Strong fourth quarter results in the uranium and Westinghouse segments provided a boost to annual results, relative to 2024. Net earnings for the quarter and the year increased by $64 million and $418 million respectively, compared to 2024, while adjusted net earnings increased by $60 million and $335 million, respectively for the quarter and for the year compared to 2024. Full year adjusted EBITDA increased by approximately $398 million to $1.9 billion compared to 2024 mainly due to the contributions from the uranium segment, which reflects an improving price environment, as well as the increase in our share of Westinghouse’s annual revenue tied to its participation in the Dukovany construction project. See non-IFRS measures for more information.
• Strong balance sheet: Thanks to our risk-mitigated financial discipline, our balance sheet remains strong.
• As of December 31, 2025, we had $1.2 billion in cash and cash equivalents and short-term investments, with $1.0 billion in total debt.
• During the year, we repaid the remaining US$200 million on our US term loan, extinguishing the term loan.
• In February, we received US$49 million from Westinghouse as our first distribution since the acquisition closed and another US$171.5 million in October, related to Westinghouse’s participation in the Dukovany construction project. In early 2026, we received another US$49 million as a distribution from Westinghouse.
• In April, we received a cash dividend of US$87 million, net of withholdings, from JV Inkai.
• Dividend: In November, to reflect the improvement in our financial performance and the additional distribution received from Westinghouse, we advanced our dividend growth plan. We increased our annual dividend to $0.24 per common share in 2025, advancing our plan to increase the dividend to $0.24 per common share by one year. See Return in our annual MD&A for more information.

Of note in 2025:

• Uranium: Fourth quarter earnings before taxes decreased by $15 million and adjusted EBITDA increased by $5 million, compared to 2024, mainly as a result of lower sales volume due to timing of sales. Annual earnings before income taxes increased by $50 million and adjusted EBITDA increased by $76 million compared to 2024. See Financial results by segment – Uranium in our annual MD&A for more information.
• Fuel services: Fourth quarter earnings before taxes increased by $13 million and adjusted EBITDA increased by $14 million compared to 2024, mainly as a result of deliveries under contracts that were entered into in an improved price environment. Annual earnings before income taxes for the year increased by $71 million while adjusted EBITDA increased by $74 million compared to 2024. See Financial results by segment – Fuel Services in our annual MD&A for more information.
• Westinghouse: Westinghouse reported net earnings increased by $17 million (our share) for the fourth quarter, compared to the same quarter last year. Over the year, Westinghouse reported a net earnings increase of $276 million in comparison to 2024. To better reflect the underlying operating performance, we use adjusted EBITDA as a performance measure for Westinghouse. In the fourth quarter of 2025, our share of Westinghouse’s adjusted EBITDA increased by $49 million, compared to the fourth quarter of 2024, while over the year, adjusted EBITDA increased by $297 million compared to 2024. In October 2025, Westinghouse made a second cash distribution of US$350 million (US$171.5 million our share) to its owners associated with the cash received in 2025 for its participation in the construction project for two nuclear reactors at the Dukovany power plant in the Czech Republic, led by Korea Hydro & Nuclear Power. See Financial results by segment – Westinghouse in our annual MD&A for more information.

Of note in 2025:

• Uranium: We produced 21.0 million pounds of uranium (our share), exceeding our revised consolidated annual production guidance of up to 20 million pounds, announced on August 28, 2025. At Cigar Lake, we produced 19.1 million pounds (100% basis), exceeding our annual expectations by 1.1 million pounds. At McArthur River/Key Lake, we produced 15.1 million pounds (100% basis), meeting our revised annual production guidance. See Uranium production overview in our annual MD&A for more information. Our average realized price in our Uranium segment continued to show improvements as prices under base-escalated and market-related contracts increased. See Financial results by segment – Uranium in our annual MD&A for more information.
• JV Inkai: Total production from JV Inkai in 2025 was 8.4 million pounds (3.7 million pounds our share) compared to 7.8 million pounds (3.6 million pounds our share) in 2024. During 2025 we received shipments containing the remainder of our share of 2024 production, about 0.9 million pounds, and the entire 3.7 million pounds of our share of Inkai’s 2025 production. See Uranium – production overview in our annual MD&A for more information.
• Fuel services: At our Fuel Services division, we produced 14.0 million kgU, including 11.2 million kgU of UF6, a production record for our Port Hope conversion facility. The improvement of the average realized price in our Fuel Services segment was driven primarily by deliveries under contracts that were entered into in an improved price environment. See Financial results by segment – Fuel Services in our annual MD&A for more information.
• Deliveries and Inventory: In addition to our uranium production, we purchased a total of 9.6 million pounds of uranium (including JV Inkai purchases). We delivered 33.0 million pounds of uranium in alignment with the commitments under our contract portfolio, and finished 2025 with a uranium inventory of 9.7 million pounds, with an average inventory cost of $61.85 per pound. At fuel services, we delivered 13.1 million kgU of combined fuel services product under contract.
• Contracting: In our uranium segment, we continued contract negotiations, successfully adding to our long-term portfolio. After meeting our 2025 delivery commitments, we have long-term commitments to deliver about 230 million pounds of uranium, including an annual average delivery volume of about 28 million pounds over the next five years, that retain exposure to the improving fundamentals as our customers look to secure their long-term needs. In Fuel Services, with strong demand and historically high pricing in the UF6 conversion market, we were successful in adding new long-term conversion contracts that bring our total contracted volumes to about 83 million kgU of UF6 that will underpin our fuel services operations for years to come.

Additional highlights

• Westinghouse participation in construction of Dukovany power plant: In the second quarter of 2025, we announced the benefits expected for Westinghouse and Cameco as a result of Westinghouse’s participation in the construction of two nuclear reactors at the Dukovany power plant in the Czech Republic, which include:
• An increase of approximately US$170 million to our share of Westinghouse’s 2025 second quarter revenue.
• Significant expected financial benefits for Westinghouse, as a subcontractor, over the term of the Dukovany construction project and related to the provision of the fuel fabrication services required for both reactors for a specified period.
• Strategic Partnership with US Government: In the fourth quarter of 2025, we, alongside Brookfield and Westinghouse, entered into a strategic partnership with the US Government, which is expected to accelerate the deployment of Westinghouse nuclear reactors in the US and globally. This collaboration provides for the US Government to arrange financing and facilitate the permitting and approvals for new Westinghouse nuclear reactors to be built in the US, with an aggregate investment value of at least US$80 billion. The launch of a nuclear power plant construction program is expected to accelerate growth in Westinghouse’s energy systems segment during the construction phase, along with its core fuel fabrication and reactor services business for the life of the reactors, strengthening our integrated fuel cycle strategy, and supporting long-term growth through rising demand for nuclear fuel products, services and technologies.

NET EARNINGS

The following table shows what contributed to the change in net earnings and adjusted net earnings (non-IFRS measure) in the three months and year ended December 31, 2025, compared to the same period in 2024.

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. We are not able to reconcile our forward-looking non-IFRS guidance because we cannot predict the timing and amounts of discrete items, which could significantly impact our IFRS results. 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, unrealized foreign exchange gains and losses, share-based compensation, and adjustments to reclamation provisions flowing through other operating expenses, that we believe do not reflect the underlying financial performance for the reporting period. In 2024, we revised our calculation of ANE to adjust for unrealized foreign exchange gains and losses, as well as for share-based compensation because it better reflects how we assess our operational performance. We have restated comparative periods to reflect this change. 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. ANE 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 2025 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 2025 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 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.

As a result of the change in ownership of Westinghouse when it was acquired by Cameco and Brookfield, Westinghouse’s inventories at the acquisition date were revalued based on the market price at that date. As these quantities are sold, Westinghouse’s cost of products and services sold reflect these market values, regardless of their historic costs. Our share of these costs is included in earnings from equity-accounted investees and recorded in cost of products and services sold in the investee information (see note 12 to the financial statements). Since this expense is non-cash, outside of the normal course of business and only occurred due to the change in ownership, we have excluded our share from our ANE measure.

Westinghouse has also expensed some non-operating acquisition-related transition costs that the acquiring parties agreed to pay for, which resulted in a reduction in the purchase price paid. Our share of these costs is included in earnings from equity accounted investees and recorded in other expenses in the investee information (see note 12 to the financial statements). Since this expense is outside of the normal course of business and only occurred due to the change in ownership, we have excluded our share from our ANE measure.

The following table reconciles adjusted net earnings with our net earnings for the three months and years ended December 31, 2025, and 2024.

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, 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.

In calculating adjusted EBITDA, we also adjust for items included in the results of our equity-accounted investees.
