Item 2 – Proposals from the Board of Directors

Item 2.a – Proposal to amend Article 9.1 of the Articles of Association to allow the Board of Directors to consist of up to seven members

The Board of Directors proposes to amend Article 9.1 of the Company’s Articles of Association to allow for the Board of Directors of the Company to consist of up to seven members, as the current Article 9.1 of the Articles of Association only allows the Board of Directors to consist of between three and six members.

Article 9.1 of the Articles of Association will be amended as follows:

Item 2.b – Proposal to elect one new additional member to the Board of Directors

With reference to item 2.a, under which it is proposed to amend Article 9.1 of the Company’s Articles of Association to change the maximum number of members of the Board of Directors, the Nomination Committee proposes to elect Mr. Thomas Thune Andersen as a new member of the Board of Directors for an initial term expiring upon the Company’s 2026 annual general meeting. The proposal under item 2.b is subject to item 2.a being adopted by the general meeting.

Description of Mr. Thomas Thune Andersen’s qualifications, including information on other management positions held:

Thomas Thune Andersen (Born 1955, nationality: Danish) currently serves as chair of the board of directors of Lloyd’s Register Group, Lloyd’s Register Foundation and VKR Holding A/S, Senior Independent Director of IMI plc and Non-Executive Director of BW Group Ltd and Lambert Energy. Additionally, Mr. Andersen has since 2018 been a member of the Danish Committee on Corporate Governance.

Previously, Mr. Andersen has served as chair of Ørsted A/S and Deep Ocean Group Holding, a non-executive Director of Green Hydrogen Systems A/S, BW Offshore and SSE plc, senior Independent Director of Petrofac plc and advisor to Hambro Perks and Arcus Infrastructure Partners. Mr. Andersen has participated in an Advanced Executive Programme (ISMP) in Economics at Harvard University, a Senior Management Programme at Columbia University and holds a Graduate Diploma in foreign relations (HD) from Copenhagen Business School. Mr. Andersen has extensive international experience from various leadership positions including at A. P. Moller Maersk and other non-executive directorships in both listed and privately held companies within energy, manufacturing, marine and related critical infrastructure, over the past years with a special focus on the energy transition.

The Board of Directors has made an independence assessment of Mr. Andersen in accordance with both the Norwegian Code of Practice for Corporate Governance and the corporate governance standards of the New York Stock Exchange and has reached the conclusion that it will consider Mr. Andersen an independent director, should he be elected at the general meeting.
