Kazatomprom

Kazatomprom (National Atomic Company Kazatomprom JSC) is the world’s largest uranium producer and a cornerstone of the nuclear-fuel and critical-minerals supply chain, headquartered in Astana, Kazakhstan. Majority-owned by the Kazakhstan sovereign wealth fund Samruk-Kazyna, it is dual-listed on the London Stock Exchange and Astana International Exchange (AIX) under the ticker KAP, with a market capitalization of roughly US$18-22 billion. The company’s attributable output represents about 20% of global primary uranium supply, and all of its mining operations are located in Kazakhstan, extracting uranium through low-cost in-situ recovery (ISR) technology. Kazatomprom also produces beryllium, tantalum and niobium products through subsidiaries such as Ulba Metallurgical Plant, positioning it within the broader critical-minerals and rare-metals space. In 2026 the company guided to a roughly 9% production increase, targeting 71.5-75.4 million pounds of uranium for the year.

Kazatomprom held 51% of Summit Atom Rare Earth Company (SARECO), a joint venture with Sumitomo Corporation set up in 2010 to recover rare earth elements from uranium-ore residue; Sumitomo reported that SARECO’s plant at Stepnogorsk opened on November 2, 2012. Lindian Resources says it has since acquired the SARECO processing facility, which it describes as previously developed and operated by Kazatomprom and Sumitomo.
