The squeeze-out of the remaining innogy minority share- holders was completed in June. As a result of this, the legal integration of innogy was concluded as well. In addition, the antitrust requirements for the divestment of parts of the Company were successfully completed. The Covid-19 pandemic presented the company with major challenges-both in the market and in terms of internal processes and procedures, which were successfully overcome. The Super- visory Board would like to thank the Management Board and all employees for all the special efforts that were and are connected with these matters. In the 2020 financial year the Supervisory Board carefully performed all its duties and obligations under law, the Company’s Articles of Association, and its own rules and procedures. It advised the Management Board in detail about the Company’s management and continually monitored the Management Board’s activities, assuring itself that the Company’s management was legal, purposeful, and orderly. At four regular meetings and one extraordinary meeting, it addressed all issues relevant to the Company. In addition, it carried out one written resolution procedure. On a regular basis, the shareholder representatives and the employee representa- tives made separate preparations for these meetings with the participation of one Dr. Karl-Ludwig Kley, or all members of the Management Board. Three Supervisory Board members were Chairman of the Supervisory Board unable to attend individual Supervisory Board meetings in 2020. Apart from that, all members attended all meetings. The Management Board regularly provided the Supervisory Board with timely and comprehensive information about significant business transactions in both written and oral form. At the meetings of the full Supervisory Board and its com- mittees, the Supervisory Board had sufficient opportunity to actively discuss the Management Board’s reports, motions, and proposed resolutions. After thoroughly examining and discussing the resolutions proposed by the Management Board, the Super visory Board voted on them when it was required by law, the Company’s Articles of Association, or the Supervisory Board’s rules and procedures. Further- more, the Supervisory Board also met on a recurring basis without the Management Board being present. In addition, there was a regular exchange of information between the Chairman of the Supervisory Board and the members of the Management Board, in particular the Chairman, during the entire financial year. In the case of particularly pertinent issues, the Chairman of the Supervisory Board was kept informed at all times. He likewise maintained contact with the members of the Supervisory Board outside of board meetings.
