JSC National Atomic Company “Kazatomprom” (“Kazatomprom” or “the Company”) announces the following update related to the Company’s 2014, 2015 and 2016 agreements (“agreements”) for expanding cooperation in the nuclear industry with China General Nuclear Power Corporation (“CGNPC”) and its subsidiaries, CGNPC Uranium Resources Company Limited (“CGNPC-URC”) and CGN Mining Company Limited (“CGN Mining”). Please see the Company’s 2018 IPO Prospectus for further information regarding the specific agreements.

Pursuant to the agreements, the parties created a joint venture, Ulba-FA LLP, for the construction of a fuel assembly plant (“Ulba-FA plant”) with an annual nameplate capacity of 200 tonnes of uranium metal content equivalent in the form of fuel assemblies (“UME”), located at the Ulba Metallurgical Plant in the East Kazakhstan Region. In accordance with the agreements, CGNPC-URC committed to procure 200 tonnes of UME annually from the Ulba-FA plant within 20 years (4,000 tonnes UME in total). The Company and CGNPC agreed that subject to Ulba-FA receiving the first fuel assembly contract from CGNPC-URC, the Company would sell to CGNPC or its affiliates up to a 49% interest in its wholly owned subsidiary, Ortalyk LLP, on market terms determined by a third-party valuation (which is underway).

Despite COVID-19-related delays in the final commissioning stages of the Ulba-FA plant, work has resumed, with commissioning and required licensing being completed in 2020. Under the current ramp-up and product qualification plan, and assuming no further delays, the first production from the Ulba-FA plant is expected near the end of 2021, with first delivery of finished, certified fuel assemblies to the customer in 2022. With respect to the purchase commitment from CGNPC-URC, the first five-year contract for the procurement of fuel assemblies was signed between Ulba-FA LLP and CGNPC-URC in December 2020, subject to approval by appropriate competent authorities. The subsequent transfer of a 49% interest in Ortalyk LLP to CGNPC is expected to be completed by 30 June 2021 (subject to corporate and governmental approvals).

Upon completing the sale of an interest in Ortalyk LLP, Kazatomprom will retain a 51% interest and CGNPC or its affiliates will acquire a 49% interest, with each partner purchasing a proportionate share of uranium production from the operation according to interest.
