In 2022, NAC Kazatomprom JSC (hereinafter - Kazatomprom or the Company) became its leader.

Disclosure of information on environmental, social and governance aspects is a call of the time and the global community, contributing to long-term and sustainable business development. Qualitative disclosure of ESG information allows us to identify significant risks and opportunities of the current business model, which contributes to more effective adaptation to new challenges. Today, ESG indicators are increasingly influencing the investment attractiveness of a company in the global market, and their disclosure is also becoming an important factor in access to capital markets.

The PwC rating is based on the results of a study that evaluates the quality, completeness and availability of ESG information in the public reporting of Kazakh companies.

Since 2019, Kazatomprom has been reporting information on approaches to sustainable development management and contribution to the achievement of the UN Global Sustainable Development Goals. With the independent assurance of non-financial information disclosed in the integrated annual report for 2021, the Company's ESG team ensured full compliance with the GRI (Global Reporting Initiative): Core Option, and also improved the quality of disclosure in accordance with the best international practices.

It should be noted that last year, Kazatomprom was second in the TOP 10 of PwC's ESG Disclosure Rating. The improvement of the Company's position is due to the fact that for Kazatomprom, the development and improvement of sustainable development practices is a significant factor in ensuring the long-term stability and competitiveness of the Company, as well as its ability to create additional value for all stakeholders, making a significant contribution to the sustainable development of the country, society and the uranium industry.
