CHAIR’S GOVERNANCE STATEMENT During the year, we began consultation with shareholders on a new compensation policy, including the introduction of more robust growth-related performance measures designed to strengthen alignment between pay, delivery and shareholder value creation. This formed part of a wider programme of engagement with our shareholders and other stakeholders, which I detail in my statement at the beginning of this Annual Report. I am pleased to report that this year’s Board evaluation, conducted internally by our Senior Independent Director, showed the Board is working effectively, while acknowledging the evaluation was conducted during a year of transition. More details on the evaluation, including key areas of focus identified for 2026, can be found in the Nomination and Governance Committee report on page 79. At WPP we have a robust and responsive approach to governance that is designed to serve the interests of our shareholders and wider stakeholders. The following pages provide further details of how we implemented that approach in 2025. We look forward to building on these foundations as we continue to evolve our governance practices in the year ahead. Philip Jansen Chair 19 March 2026 One of the principal outputs of this process was the new strategy announced by the management team in February. Monitoring and supporting the progress of its execution is our number one priority for the year ahead. The Board is fully aligned with the strategy and believes WPP has what it needs to succeed in today’s business and marketing environment. That said, market conditions are fast-changing, geopolitical and macroeconomic uncertainty is high, and any turnaround comes with risk. We describe our principal risks and uncertainties, and our approach to managing them, from page 55 of this report. Maintaining an appropriate balance of skills and experience at executive and Board level, and looking ahead to the next generation of leaders, is a continuous element of the Board’s oversight. The Board has engaged regularly with senior leaders and emerging talent, supporting the Company’s objective of a high-performing team today and a strong pipeline for the future. Cindy has made a number of leadership appointments and changes to align with the new strategy, which the Board has supported. While the Board itself has a good mix of sector background, expertise and length of tenure, we have continued to review composition to ensure we have the right make-up to support the new strategy. The Board recognises the importance of diversity to good governance and decision- making, and WPP continues to exceed the UK board diversity recommendations of the FTSE Women Leaders Review and the Parker Review. We are pleased that, as at the date of this report, we have gender parity on the Board, and that three of the most senior roles – CEO, CFO and Senior Independent Director – are held by women. On behalf of the Board, I am pleased to introduce the Corporate Governance section of WPP’s Annual Report for 2025. This section outlines how the Board has applied the principles of the UK Corporate Governance Code, and describes our most important activities during the year. Planning for and delivering leadership succession is a critical component of effective governance and in 2025 the Board oversaw the appointment of a new Chief Executive Officer following the announcement in June that Mark Read would be retiring from the role. In July we announced that Cindy Rose would step down as a Non-Executive Director and become CEO of the Company in September. You can find more details of this process in the Nomination and Governance Committee report on page 79. The Board’s job is to support the health and resilience of the Company and to ensure effective governance, controls and accountability. In 2025 that meant intensifying oversight and constructive challenge, and making sure the organisation was positioned for an effective reset. With a new Chair and CEO in place, the Board focused on how performance is monitored across the business, how issues are escalated, and how plans translate into delivery. We have given particular attention to growth in and retention of key client relationships, alongside new business performance, and to ensuring clear ownership of outcomes. We have also continued to look closely at performance management, career development and capability-building. At WPP we have a robust and responsive approach to governance that is designed to serve the interests of our shareholders and wider stakeholders.” PHILIP JANSEN CHAIR, WPP WPP ANNUAL REPORT 2025 64 CORPORATE GOVERNANCE

HOW OUR BOARD ENGAGES WITH STAKEHOLDERS Our stakeholders are central to our strategy and critical to the long-term success of our business. PRINCIPAL DECISIONS The Board oversees our approach to stakeholder engagement as we seek feedback and make decisions for the long-term benefit of WPP. For each matter that comes before the Board for decision, the Board considers the likely consequences of any decision in the long term, identifies stakeholders who may be affected, and carefully considers their interests and any potential impact as part of the decision-making process. THE COMPANY’S STAKEHOLDER GROUPS: SHAREHOLDERS GOVERNMENTS AND REGULATORS CLIENTS, PARTNERS AND SUPPLIERS PEOPLE KEY DECISION €1 BILLION BOND ISSUANCE KEY DECISION ELEVATE28 STRATEGY BACKGROUND The Board regularly reviews the Company’s debt profile, liquidity and opportunities to strengthen the balance sheet. In December 2025, we successfully issued a €1 billion bond, rated ‘BBB’ by S&P and ‘Baa2’ by Moody’s, consistent with an investment-grade rating. BACKGROUND In July we announced that Cindy Rose would step down as a Non-Executive Director and become CEO of the Company in September. Along with our Interim Results in August, the Company also announced that a review of the strategy would be undertaken, which would be led by Cindy. DECISION This decision garnered significant interest and demand, evidenced across a series of well attended investor meetings. The transaction proceeded to generate a total order book exceeding €2.9 billion from a diverse array of institutional investors. This robust oversubscription of 2.9 times underscores investor confidence in WPP’s credit profile and leading market position. DECISION On taking the role, Cindy had a clear thesis about what we need to do differently. In her first six months as CEO, that thesis was tested through detailed analysis and, more importantly, direct conversations with shareholders, clients and feedback from our people. The Board received varied and comprehensive insights throughout the strategy review process. Insights were robustly and representatively informed by stakeholder views in addition to competitor analysis. Feedback from clients was clear and consistent: they value our talent, capabilities and scale, but want WPP to be easier to navigate, genuinely integrated and able to move at the pace modern marketing demands. The Board considered this feedback, alongside wider stakeholder input, in determining the outcome of the strategic review. STAKEHOLDERS CONSIDERED STAKEHOLDERS CONSIDERED OUTCOME The Company intends to use the net proceeds from the offering to fund general corporate purposes, including the refinancing of existing indebtedness as WPP continues its prudent capital allocation and financing strategy. The issuance also pre finances the 2026 maturity, strengthening liquidity and reducing near term refinancing risk. OUTCOME In February 2026 we announced Elevate28, our multi‑year plan to simplify WPP, restore growth, and create a company that is fit for the future and built to win. Monitoring and supporting the progress of execution for Elevate28 is our number one priority for the year ahead. See page 10 for further details. WPP ANNUAL REPORT 2025 72 CORPORATE GOVERNANCE


 
OUR APPROACH TO ENGAGEMENT Our stakeholder engagement processes enable our Board to understand what matters to stakeholders most, consider all relevant factors and select the course of action that best delivers long-term value for our stakeholders and protects their interests, reflecting what are referred to as Section 172 factors. As a Jersey incorporated company, WPP is not subject to UK legislation. However, as a matter of good governance and in order to comply with the provisions of the 2024 UK Corporate Governance Code (the 'Code’), the Board considers the matters described in Section 172 of the Companies Act 2006 in its decision-making. Section 172 factors are not only considered at Board level – they are part of our culture and help drive our business. Illustrations of this can be found throughout the Strategic Report. Please see page 87 for details of ongoing preparatory work for the introduction of Provision 29 of the Code ENGAGEMENT IN ACTION DURING 2025 The table below illustrates our direct and indirect Board engagement with various stakeholders, in addition to details on how the Company has engaged with each of these stakeholder groups on an operational level and the outcomes achieved.

Shareholders are being asked to approve an updated Policy at our 2026 AGM. For more detail see page 93.

Leadership succession planning and delivery are essential to effective governance. In 2025, the Board oversaw the process to appoint a new Chief Executive Officer after the announcement in June that Mark Read would be stepping down from the position. Russell Reynolds, who were formally appointed to assist with the search, remained independent of the Company and all the Directors, in addition to being a signatory of the voluntary code of conduct for executive search firms. Further information on the appointment search and process can be found on page 80. Following the announcement in July 2025 that Cindy Rose would step down as a Non-Executive Director and become CEO of the Company on 1 September 2025, the Committee reviewed - and continues to review - succession planning across the Board and its committees to support the execution of the Company’s corporate strategy. The 2025 Board performance review, conducted internally by the Senior Independent Director, was another key focus. I am pleased that this review affirmed the continued effective operation of both the Committee and the Board, while also pinpointing specific opportunities for development in 2026. The Committee continued to implement the Board Diversity Policy, in accordance with the UK Corporate Governance Code, and review progress made against the agreed objectives within it, details of which can be found on page 65, alongside gender and ethnicity information. The Board recognises the importance of diversity to good governance and decision-making and we are pleased that, at the time of reporting, we have gender parity on the Board and that three of the most senior roles – CEO, CFO and Senior Independent Director – are held by women, in addition to two members of our Board being from non- white ethnic minority backgrounds.

Further detail on the key stages of the succession process is outlined below: CHIEF EXECUTIVE OFFICER APPOINTMENT PROCESS Succession planning for all Directors, including the Executive Directors, is considered on an ongoing basis. The Committee also has oversight of succession at Executive Committee and senior management levels to promote effective leadership succession, and ensure that it is fully aligned to the Company’s strategy. After 30 years with the Company, including seven years as CEO, Mark Read stepped down from the Board and as CEO, effective 1 September 2025. The Committee, led by the Chair, oversaw the search for and appointment of a new CEO. The process was thorough and inclusive.
