Cameco outlines IPO registration plan while Westinghouse details AP1000 deployment pipeline

IPO registration and regulatory limits

Cameco announced it is registering for a proposed IPO of Westinghouse ahead of its quarterly results call. The company said the number of shares to be offered and the price range have not been determined and that the offering would be subject to market and other conditions. Cameco also said it is extremely limited in what it can disclose about the IPO under US Securities and Exchange Commission rules.

Westinghouse featured prominently in Cameco’s quarterly update for the quarter ended 30 June, including discussion of its technology platform across the nuclear power value chain and a global deployment pipeline for AP1000 projects. The business is currently owned 49% by Cameco and 51% by Brookfield, following a 2023 transaction that followed Westinghouse’s 2018 acquisition out of bankruptcy by Brookfield Business Partners.

Pipeline for 91 potential AP1000 reactors

Cameco said Westinghouse’s technology is used by 57% of the global operating fleet of 417 reactors. The materials it filed describe deployment opportunities for 91 potential AP1000 reactors totaling about 105GWe across global markets, with timing and ordering based on closeness to final investment decisions.

The pipeline includes up to 10 AP1000 units supported through American Nuclear Supply Chain Loans announced by the US Department of Energy earlier this year, with a commercial operation timeframe by the mid-2030s. It also cites up to 10 additional US units supported through a strategic partnership among Cameco, Brookfield and the US Department of Commerce announced in 2025, targeting commercial operation by the mid-to-late 2030s.

Other opportunities listed include resumption of the two-unit VC Summer project with early-to-mid 2030s commercial operation; three units at Lubiatowo-Kopalino in Poland with operations in the mid-2030s; two units each in Bulgaria (Kozloduy units 7 and 8) and Ukraine (Khmelnitsky units 5 and 6) for mid-to-late 2030s operation; 11 “FEED-Stage Projects” in the Netherlands, Slovenia, Finland/Sweden, and the USA with a late-2030s timeframe; and up to 51 units across Canada, India, Saudi Arabia, Slovakia, the USA and other European countries with a late-2030s to early-2040s deployment window.

Procurement and long-lead planning focus

Westinghouse’s management said the company’s complete reactor design and operating experience support procurement aspects of new projects and that few bottlenecks are perceived around construction, while also noting risks.

Cameco President and Chief Operating Officer Grant Isaac emphasized the significance of US government funding and the importance of securing long-lead items to support construction projects. Management also pointed to a standardized design, sequential construction projects, and “simplifying” projects by incorporating lessons learned as factors intended to reach Nth-of-a-kind deployments more quickly.

Cameco’s materials also included illustrative economics contrasting near-term deployments with Nth-of-a-kind deployments, including estimates that the nuclear construction period (from first nuclear concrete to commercial operation) is around 66 months per unit for near-term deployments and reduces by 20–30% for Nth-of-a-kind deployments.
