Non-Integral Shareholding in Wintershall Dea

In May 2019, Wintershall Holding GmbH and DEA Deutsche Erdoel AG merged to form Europe’s leading independent natural gas and oil company: Wintershall Dea.

The company with German roots and headquarters in Kassel and Hamburg explores for and produces gas and oil in 11 countries worldwide in an efficient and responsible manner. With activities in Northern Europe, Latin America and the MENA region (Middle East and North Africa), Wintershall Dea has a global upstream portfolio. Furthermore, with its participation in natural gas transport, it is also active in the midstream business. The company stands for over 120 years of experience as an operator and project partner along the entire E&P value chain. The company employs around 2,500 people worldwide from almost 60 nations.

Due to increasing restrictions on its ability to influence its investments in Russia, largely as a result of government interference, Wintershall Dea deconsolidated its Russian segment in the fourth quarter of 2022 and subsequently recognized it as a financial asset measured at fair value in accordance with IFRS 9. In addition, on January 17, 2023, Wintershall Dea announced its full exit from Russia in compliance with all legal requirements.

Following the approval of all relevant authorities, BASF and LetterOne successfully completed the merger of Wintershall and DEA on May 1, 2019. BASF holds 72.7% of the ordinary shares in Wintershall Dea AG; 27.3% are held by LetterOne. The preference shares previously held by BASF were converted into ordinary shares on May 1, 2022.

In 2022, Wintershall Dea had revenues and other income of €18.7 billion (€16.9 billion excluding segment Russia), income from operations before depreciation, amortization and exploration (EBITDAX) of €7.7 billion (€5.9 billion excluding segment Russia) and adjusted net income of €2.4 billion (€928 million excluding segment Russia). Total production of Wintershall Dea (excluding Libya onshore) was 597,000 barrels of oil equivalent per day (BOEPD) (321,000 BOEPD excluding segment Russia). As of December 31, 2022, proven and probable reserves stood at 1.4 billion BOE, corresponding to a reserve to production ratio of 12 years.
