Cameco Reports 2025 Third Quarter Results

Press Release

Cameco announces third quarter results: financial performance on track for strong finish to the year; nuclear fundamentals strengthened by transformational partnership to deploy Westinghouse reactors in the US; annual dividend declared

Cameco (TSX: CCO; NYSE: CCJ) today reported its consolidated financial and operating results for the third quarter ended September 30, 2025, in accordance with International Financial Reporting Standards (IFRS).

“Our year-to-date financial results demonstrate strong performance across our uranium, fuel services, and Westinghouse segments, underscoring the resilience of our strategy in a dynamic market that is being continually reinforced by tremendous positive momentum,” said Tim Gitzel, Cameco’s chief executive officer. “Driven by disciplined long-term contracting and management of our supply sources, alongside strategic partnerships that can add significant future value, we are positioned at the forefront of the global nuclear resurgence.

“As the global energy landscape evolves, nuclear continues on a path towards robust expansion and meaningful transformation. We’re seeing significant attention across all areas of the nuclear fuel cycle, beyond uranium mining – but a good narrative won’t turn a turbine. Cameco is in an exceptional position, with decades of experience operating unique and complex assets that are critical to the long-term health of the nuclear industry, and a deep understanding of how to build value across the nuclear fuel markets. That experience allows us to be selective in committing unencumbered productive capacity under long-term contracts, while ensuring alignment with customer needs, maintaining downside protection, and preserving exposure to future market price improvement.

“Our supply sourcing flexibility is a key advantage. We fulfill sales commitments through a mix of production, inventory, product loans, and both market and long-term purchases, all planned years ahead of time to provide for flexibility in how we source the supply we need. This quarter reflects that flexibility, as we adjusted a number of the supply levers we have at our disposal, including our planned market purchases and product loans, to help offset the impact of expected changes in our 2025 uranium production outlook. While the development delays at McArthur River and Key Lake that we announced in August have reduced our consolidated production forecast, we expect to meet our delivery commitments – just as we always have – by balancing all available sources with a focus on value creation, risk management, and sustainability.
“Beyond core operations, we were delighted to announce the transformative partnership with Brookfield Asset Management and the US Government last week, which we expect to accelerate global Westinghouse reactor deployment. The partnership provides for the US Government to arrange financing and facilitate the permitting and approvals of new Westinghouse nuclear reactors with an aggregate investment value of at least $80 billion (US). This milestone is expected to strengthen energy security, revitalize supply chains, and creates significant growth opportunities for both Westinghouse and for Cameco. It reaffirms our position as a driving force behind nuclear expansion and leverages our integrated fuel cycle and downstream investments to meet rising demand for carbon-free, reliable baseload power.

“Nuclear energy is gaining momentum worldwide with its reliability, scalability, and carbon-free attributes. That strength is reflected in Cameco’s improving performance as we navigate challenges and seize opportunities. We remain focused on strong partnerships and long-term value creation, enhancing energy and national security objectives, and advancing nuclear as a cornerstone of the clean energy transition.”

Third Quarter Highlights

Financial Highlights

• Consolidated performance: Results in the third quarter were comparable to 2024 with a small net loss, adjusted net earnings of $32 million, and adjusted EBITDA of $310 million. Although third quarter sales volumes were lower overall, our average realized prices continue to improve in both uranium and fuel services segments, and equity earnings from our investment in Westinghouse were stronger than in 2024. During the first nine months of the year, net earnings of $391 million, adjusted net earnings of $410 million and adjusted EBITDA of $1.3 billion were significantly higher than in 2024. See Consolidated financial results in the third quarter MD&A for more information.
• Strong balance sheet: Thanks to our risk-managed financial discipline, our balance sheet remains strong. As of September 30, 2025, we had $779 million in cash and cash equivalents, $1.0 billion in total debt and a $1.0 billion undrawn revolving credit facility.
• Uranium: In our core uranium segment, third quarter earnings before taxes were $172 million and adjusted EBITDA was $220 million compared to $171 million and $240 million in 2024, respectively, mainly as a result of lower sales volume than in the third quarter of 2024. Earnings before income taxes for the first nine months of the year were $681 million while adjusted EBITDA was $861 million, compared to $615 million and $788 million in 2024, respectively. Average realized price continued to show improvements as prices from fixed price contracts increased. See Financial results by segment – uranium in our third quarter MD&A for more information.
• Fuel Services: In our fuel services segment, third quarter earnings before taxes were $17 million and adjusted EBITDA was $24 million compared to $17 million and $28 million in 2024, respectively, mainly as a result of a decrease in sales volumes. Earnings before income taxes for the first nine months of the year were $129 million while adjusted EBITDA was $156 million, compared to $71 million and $96 million in 2024. See Financial results by segment – Fuel services in our third quarter MD&A for more information.
• Westinghouse: Westinghouse reported a net loss of $32 million (our share) for the third quarter, up from a loss of $57 million (our share) in the third quarter of 2024. Over the first nine months of the year, Westinghouse reported net earnings of $32 million, in comparison to a loss of $227 million in the same period in 2024. To better reflect the underlying operating performance, we use adjusted EBITDA as a performance measure for Westinghouse. In the third quarter of 2025, our share of Westinghouse’s adjusted EBITDA was $124 million, compared to $122 million in the third quarter of 2024, while for the first nine months adjusted EBITDA was $569 million, compared to $320 million in 2024. In October, Westinghouse received the cash associated with its participation in the construction project for two nuclear reactors at the Dukovany power plant in the Czech Republic, and a distribution was made to the partners in October. Cameco received $171.5 million (US) representing our 49% share. See Our earnings from Westinghouse, in our third quarter MD&A for more information.
• Dividend: With improving financial performance and the receipt of the additional distribution from Westinghouse in October, we are accelerating the increase of our dividend to $0.24 per common share, with our annual dividend to be paid on December 16, 2025. See Dividend in our third quarter MD&A for more information.

Adjusted net earnings and adjusted EBITDA are non-IFRS measures, see page 5 of the full news release.

Operational Highlights

• Uranium: As announced in August, we now expect to produce between 14 million and 15 million pounds of U₃O₈ (100% basis; 9.8 million to 10.5 million pounds our share) in 2025 from McArthur River/Key Lake (previously 18 million pounds U₃O₈on 100% basis; 12.6 million pounds our share). Performance to date at Cigar Lake has been strong, creating an opportunity to potentially produce 19 million pounds U₃O₈ (100% basis) which would offset up to 1 million pounds (100% basis) of the shortfall at the McArthur River/Key Lake operation. See Our operations in our third quarter MD&A for more information.
• JV Inkai: JV Inkai continues to target 2025 production of 8.3 million pounds (100% basis) of uranium of which our purchase allocation is expected to be 3.7 million pounds. The first shipment from JV Inkai containing our remaining share of 2024 production (approximately 900,000 pounds) and approximately 2.0 million pounds of our share of Inkai’s 2025 production, is currently in transit and expected to arrive at the Blind River refinery in early November. The majority of our remaining share of 2025 production is expected to be delivered before the end of 2025. See Our operations- Uranium 2025 Q3 Updates in our third quarter MD&A for more information.
• Fuel Services: At our Fuel Services division, our annual production expectation, which includes UF6 conversion, UO2 conversion, and heavy water reactor fuel bundles, remains between 13 million and 14 million kgU. At Port Hope, we continue to work towards achieving a UF6 production rate of 12,000 tonnes per year, closely aligned with our licensed capacity, in order to satisfy our book of long-term commitments and demand for conversion services. See Our Operations – Fuel Services 2025 Q3 Updates in our third quarter MD&A for more information.

Marketing Highlights

• Deliveries and inventory: In the third quarter, we produced 4.4 million pounds of uranium (our share), purchased 1.4 million pounds (purchased at an average unit cost of $82.51 per pound ($60.13 (US) per pound)) and borrowed 2 million pounds under product loan facilities. See Financial results by segment – Uranium in our third quarter MD&A for more information. After delivering 6.1 million pounds in the third quarter, our uranium inventory was 10.0 million pounds on September 30, 2025, with an average inventory cost of $47.56 per pound.
• Contracting: In our uranium segment, over the next five years, we have contracts in place for average annual deliveries of over 28 million pounds of U₃O₈ per year, with commitments higher than the average in 2025 through 2027, and lower than the average in the years 2028 and 2029. As the market continues to improve, we expect to continue layering in volumes that capture greater future upside using market-related pricing mechanisms.

2025 Outlook Update

• Production: As a result of the changes in our production plans noted above, we now expect our share of production of U₃O₈ to be up to 20 million pounds for 2025.
• Market purchases: We have reduced our outlook for market purchases to up to 1 million pounds (previous outlook up to 3 million pounds) as a result of our utilization of standby product loan facilities to offset the impact of the expected reduction in our 2025 production on our inventory balance.
• Sales/delivery volumes: We have narrowed our guidance for the sales/deliveries volumes in our uranium segment to 32 to 34 million pounds (previously 31 to 34 million pounds) as we have greater confidence in the timing of potential uranium deliveries as we approach the end of the year.

Additional Highlights

• Strategic Partnership with US Government: Subsequent to the quarter, we, alongside Brookfield, entered into a strategic partnership with the US Government expected to accelerate the deployment of Westinghouse nuclear reactors in the US. This collaboration provides for the US Government to arrange financing and facilitate the permits and approvals for new Westinghouse nuclear reactors to be built in the US, with an aggregate investment value of at least $80 billion (US). 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.
• Changes to the executive team: consistent with prudent succession planning and with Cameco’s ongoing commitment to execution of its balanced and disciplined strategy, effective January 1, 2026, the following changes will be made to the executive team:
  • Lisa Aitken will be appointed senior vice-president and chief marketing officer
  • David Doerksen will assume the role of senior advisor, marketing until March 31, 2026, at which time he is retiring
• With these changes in the senior leadership team, we expect to continue to have the right people in the right positions, with the appropriate experience to help the company achieve its vision of powering a secure energy future.
