Kazatomprom is a multinational resource extraction company founded in 1997. It is the world’s largest producer and seller of natural uranium, providing over 40% of global primary uranium supply in 2018.

Kazatomprom's uranium is used solely for the generation of carbon-free nuclear power around the world. 

The company is Kazakhstan’s national operator for the export and import of uranium and its compounds, nuclear power plant fuel, special equipment and technologies.

This status allows the Company to benefit from certain privileges, including, among other things, obtaining subsoil use agreements through direct negotiation with the Government of the Republic of Kazakhstan, which effectively grants Kazatomprom priority access to the abundant, high-quality, low-cost, in-situ recovery (“ISR”)-conducive uranium deposits in the Republic of Kazakhstan.
