Corporate governance

As Chairman of the Board of Directors, I believe that high standards of corporate governance are fundamental to our business and are implemented and supported through appropriate internal policies and procedures. The responsibility for ensuring this framework is effective lies with the Board.  The Board of Directors maintains robust standards of corporate governance and has a number of formally Retained Matters reserved for the Board.

We believe that good corporate governance improves long-term success and performance, simultaneously manages risks, and provides an underlying framework of commitment and transparent communications with stakeholders. Consequently, the Company has adopted the Quoted Companies Alliance Corporate Governance Code, which is appropriate for the Company’s size and structure. The Board issued a statement of compliance with the Code on 24 March 2026.
