External evaluation

In line with the three‑year evaluation cycle, the 2026 evaluation was externally facilitated. Christopher Saul

was appointed as the independent evaluator, and the Chair and Group Company Secretary agreed the

scope and approach for the evaluation, ensuring alignment with the Company’s governance framework

and the 2024 Code. He attended the March Board and Committee meetings as an observer, and met

with Board members and members of the Group Executive Committee for their input. His report, with

recommendations, was presented to the Board at its May 2026 meeting and an update on the actions

will be provided in next year’sannual report. Christopher Saul has no other connection to the Company or

individual Directors.

Progress against our 2025 evaluation actions
ActionsProgress
Talent and Succession–Focus on senior leadership succession and the Board’s exposure to senior management.–With the creation of the People & Remuneration Committee, all non-Board people‑related matters have been consolidated under one Committee. This provides consistency and wider context around people discussions. This also provides clearer accountability around Board talent engagement, which is now led by the Chair of the Committee with the support of the Chief People Officer and Group Company Secretary.–As part of an induction for Directors into the new Committee, a focused deep‑dive session on people and culture was undertaken to support the expanded remit of the revised Committee led by senior management from the respective teams. –Across the year, a series of roundtable engagement sessions were held with participants from the talent leadership programme, increasing the Board’s exposure to senior management and the wider talent pipeline.–The appointment of Zoë Yujnovich as Chief Executive and Emma Hardaker-Jones as Chief People Officer in the year has demonstrated senior leadership succession in action and brought a refreshed approach to how talent exposure to the Board is managed.
Governance framework–Review the Committee structure particularly in respect of risk, sustainability, reputation, operational and financing matters.–Assess if the continued ownership of all the Company’s Group Principal Risks by the Audit & Risk Committee remains the most optimal and time efficient oversight model.–Building on the prior year action around committee structure and external benchmarking, a revised committee framework was implemented to better reflect the fast moving external environment that the Company operates in, while continuing to give appropriate focus to key elements of risk, safety and operational performance. This also included the re-allocation of Group Principal Risks. –Sustainability and reputation oversight: A Responsible Business Committee was established to provide focused oversight of sustainability and the environment.–Safety and capital delivery: A Safety & Operations Committee was established with responsibility for safety oversight and the capital delivery programme.–Risk management: Each committee now assumes responsibility for Group Principal Risks within its remit, enabling more focused and specialised risk reviews. The Audit & Risk Committee retains overall ownership of the risk framework, ensuring cohesive oversight across the organisation.
