 Governance Code, with regard to the effectiveness of internal controls. This year the Committee considered the steps that are being taken to implement a “Material Control and Assurance Plan” to address the requirements of the new UK Corporate Code Provision 29, effective 1 January 2026. This is a top-down, risk-led methodology to support the new disclosures required with effect from the 2026 financial year. We aim to achieve a proportionate and practical response to the new declaration, and key to this is the identification of “material controls”. The foundation of the work we undertook was looking at the definition of material control, and we have worked with peers, accountancy firms and our auditors to understand emerging best practice in this area of corporate governance. We have an existing SOX program and have therefore considered the interaction between the two, ensuring that the frameworks are complementary. Throughout 2025, the team will review the mapping of controls to material risks and the Committee have oversight of this process. In 2024, the Committee, together with the Sustainability Committee, have continued to follow the landscape of environmental, social and governance (ESG) reporting requirements. This year we are adopting new climate disclosures in our reporting, and we are aiming to align with IFRS S2 on climate-related disclosures. We think this will place us in a good position for future years when reporting becomes mandatory. I have appreciated the support I have received from my fellow Committee members this year. In particular I would like to thank Simon McKeon for the insight and challenge that he brought as a member of the Audit & Risk Committee. The membership of the Committee was reviewed following Simon’s departure and as part of the planned refreshment of the Board. I am pleased that Kaisa Hietala, Joc O’Rourke and Sharon Thorne joined the Committee in 2024. Jennifer Nason also joined the Committee with effect from 17 February 2025. This has brought depth to the Committee both in number of members and the range of experience each Director brings. I trust you find this report a useful account of the work of the Committee during the year. Simon Henry Audit & Risk Committee Chair 19 February 2025 Audit & Risk Committee members 1,2,3,4
