WPP NOTICE OF 2026 AGM

EXPLANATORY NOTES TO THE NOTICE OF ANNUAL GENERAL MEETING

Resolutions 1 to 17 will be proposed as ordinary resolutions that will be passed if more than half of the votes are cast in favour of the particular resolution. Resolutions 18 to 20 will be proposed as special resolutions that will be passed if not less than two-thirds of the votes cast are in favour of the particular resolution.

Voting on all resolutions at the AGM will be by way of a poll rather than a show of hands. This reflects best practice and means that all the votes cast, and not just those of the shareholders present, are taken into account.

The poll results will be notified to the FCA and published on the Company's website wpp.com/investors as soon as possible after the conclusion of the Meeting.

RESOLUTION 1: REPORT AND ACCOUNTS

The Directors must present to shareholders at the Annual General Meeting the report of the Directors and the accounts of the Company for the year ended 31 December 2025. The report of the Directors, the accounts, the report of the Compensation Committee and the report of the Company's auditors on the accounts, are contained within the 2025 Annual Report and Accounts.

RESOLUTION 2: DECLARATION OF FINAL DIVIDEND

The amount of the final dividend recommended by the Directors is 7.5 pence per ordinary share to be paid on 3 July 2026 to the shareholders on the register at the close of business on 5 June 2026. Final dividends must be approved by shareholders but must not exceed the amount recommended by the Directors.

RESOLUTION 3: COMPENSATION COMMITTEE REPORT

Resolution 3 proposes the approval of the Compensation Committee report by shareholders.

The report, which is made on behalf of the full Board, explains the different elements which comprised executive compensation in 2025, including how base salaries and short-term and long-term incentive compensation were determined for Executive Directors of the Company and for Senior Executives of the Company and Group operating companies. Payments made to the Non-Executive Directors, as well as details of their shareholdings in the Company, are also set out in the Compensation Committee report. In addition, the Company's executive share ownership policy, the utilisation of the share incentive plans and the provision of other benefits are explained. The vote on this resolution is advisory in nature. Accordingly, payments made or promised to the Directors will not have to be repaid, reduced or withheld in the event that this resolution is not passed.

RESOLUTION 4: DIRECTORS' COMPENSATION POLICY

Resolution 4 proposes the approval of the Directors' Compensation Policy by shareholders. The policy is included in the Compensation Committee report in the 2025 Annual Report and Accounts on pages 103-114. The vote on the Directors' Compensation Policy is a binding vote and if approved, will take effect from the date of the Meeting. A new Directors' Compensation Policy will be put to shareholders again no later than the Company's AGM in 2029.

RESOLUTIONS 5 TO 14: RE-ELECTION OF DIRECTORS

In accordance with the Company's Articles of Association and Code, all Directors who held office on the date seven days before the date of the notice of Annual General Meeting will retire from office at the AGM and all will stand for election or re-election by the shareholders. Each of the Directors bring a wide range of skills, experience and knowledge to the Board which supports the Company's strategy. Our Non-Executive Directors demonstrate expertise from a range of industries including technology, marketing, financial services, fast-moving consumer goods and pharma, representative of our customer base. The individual and combined expertise and backgrounds of each Director makes a significant contribution to the functioning of the Board and its Committees and the long-term sustainable success of the Company.

Following the 2025 annual performance review exercise, the Board considers that each of the Directors standing for re-election continues to make an effective and valuable contribution to the Company and demonstrates commitment to their role. The Board is content that each Non-Executive Director offering himself or herself for re-election is independent in character and that there are no relationships or circumstances likely to affect his or her character or judgement. Accordingly, on the recommendation of the Nomination and Governance Committee, the Board recommends that all Directors standing for re-election continue to serve as Directors of the Company.

EXPLANATORY NOTES TO THE NOTICE OF ANNUAL GENERAL MEETING

WPP NOTICE OF 2026 AGM

RESOLUTIONS 15 AND 16: RE-APPOINTMENT OF AUDITORS

The auditors of the Company must be appointed at each Annual General Meeting. Resolution 15 proposes the re-appointment of PricewaterhouseCoopers LLP, to hold office until the conclusion of the next Annual General Meeting to be held in 2027.

On the recommendation of the Audit Committee, the Board proposes that PricewaterhouseCoopers LLP be re-appointed as the Company's auditor.

The Audit Committee has confirmed to the Board that its recommendation is free from third party influence and that no restrictive contractual provisions have been imposed on the Company limiting the choice of auditor.

Resolution 16 gives authority to the Audit Committee to determine the auditor's remuneration. In line with the Code, the Audit Committee considers and approves audit fees. Details of the remuneration paid to the auditor for the year ended 31 December 2025 (including non-audit fees) are set out on page 89 of the Annual Report.

RESOLUTION 17: AUTHORITY TO ALLOT SHARES

Resolution 17 proposes to seek renewal of the authority given to the Directors to allot ordinary shares. The £71,920,157 nominal amount of relevant securities to which this authority will relate represents approximately 66.6% of the nominal amount of the issued ordinary share capital of the Company as at 12 March 2026 (excluding treasury shares). This amount complies with guidelines issued by the Investment Association. In accordance with the Investment Association guidelines, one-third of the Company's issued ordinary share capital (excluding treasury shares) as at 12 March 2026 will be applied (if at all) to pre-emptive rights issues only. The Directors are aware of the latest Share Capital Management Guidelines published by the Investment Association in February 2023, which update the previous guidance to allow this authority to incorporate all pre-emptive offers, not just pre-emptive rights issues. The Directors have decided that they will propose limiting the relevant limb of the allotment authority to rights issues in line with past practice and will continue to review market practice and consider the current limitation to rights issues provides sufficient flexibility to the Company at present. As at the date of this Notice, the Company holds 12,591,893 treasury shares which represent approximately 1.2% of the total ordinary share capital in issue (excluding treasury shares) as at 12 March 2026. Except pursuant to the employee share schemes and the satisfaction of deferred consideration under certain acquisition agreements to which the Company is a party, the Directors have no present intention of allotting ordinary shares. The authorities conferred pursuant to resolutions 17 and 18 to 20 will expire on the date of the Annual General Meeting in 2027 or 8 August 2027, whichever is earlier.

RESOLUTION 18: AUTHORITY TO PURCHASE OWN SHARES

In certain circumstances, it may be advantageous for the Company to purchase its own ordinary shares and resolution 18 seeks authority from shareholders to authorise the Directors to make such purchases in the market.

While the Directors have no present intention of exercising the authority sought under resolution 18, the Directors consider it desirable for this general authority to be available to provide additional flexibility in the management of the Company's capital resources. The Directors intend to implement the authority only when, in light of market conditions prevailing at the time, they believe that the effect of any such purchases will enhance earnings per share in the medium to long-term and will be in the best interests of the Company and its shareholders generally. Any ordinary shares purchased under this authority would ordinarily be cancelled and the number of ordinary shares in issue will be reduced accordingly, though the Company has the option to hold them as treasury shares. The purchase price will be paid out of distributable profits.

The total number of warrants and options to subscribe for ordinary shares that are outstanding as at 12 March 2026 is 28,525,475. The proportion of issued share capital that they represented at that time was 2.6% (excluding treasury shares) and the proportion of issued share capital that they will represent as at that date if the full authority to buy back ordinary shares (existing and being sought) is used and if the ordinary shares bought back are cancelled, will be 2.9% (excluding treasury shares).

Resolution 18 specifies the maximum number of ordinary shares which may be purchased (representing approximately 10% of the Company's issued ordinary share capital as at 12 March 2026, excluding treasury shares) and the minimum and maximum prices at which they may be bought, reflecting the requirements of the UK Listing Rules.

EXPLANATORY NOTES TO THE NOTICE OF ANNUAL GENERAL MEETING

WPP NOTICE OF 2026 AGM

RESOLUTIONS 19 AND 20: DISAPPLICATION OF PRE-EMPTION RIGHTS

The authority being sought in resolutions 19 and 20 to allot shares without first offering them to existing shareholders enables the Company to raise capital quickly and easily when needed. This is in line with institutional shareholder guidance, and in particular with the Pre-emption Group's revised Statement of Principles on Disapplying Pre-Emption Rights published in November 2022 (the Statement of Principles).

The authority granted in resolution 19 would be limited to:

(a) allotments or sales in connection with pre-emptive offers and offers to holders of other equity securities if required by the rights of those securities, or as the Board otherwise considers necessary;

(b) otherwise, allotments or sales up to an aggregate nominal amount of £5,394,011 (representing approximately 5% of the issued ordinary share capital of the Company (excluding treasury shares) as at 12 March 2026, the latest practicable date prior to publication of this Notice).

Resolution 20 is intended to give the Company flexibility to make non-pre-emptive issues of ordinary shares in connection with acquisitions and other capital investments as contemplated by the Statement of Principles. The power under resolution 20 is in addition to that proposed by resolution 19 and would be limited to allotments or sales of up to an aggregate nominal amount of £5,394,011 (representing an additional 5% of the issued ordinary share capital of the Company (excluding treasury shares) as at 12 March 2026, the latest practicable date prior to publication of this Notice).

The Directors confirm that there are presently no plans to allot ordinary shares wholly for cash other than pursuant to the employee share schemes and the satisfaction of deferred consideration under certain acquisition agreements. Shares allotted under an employee share scheme are not subject to the pre-emption rights.

For this purpose, an acquisition or specified capital investment means one that is announced contemporaneously with the issue of share capital, or that has taken place in the preceding 12-month period and is disclosed in the announcement of the issue.

Whilst, at this time, the Directors have not proposed the adoption of the increased limits of 10% set out in the Pre-Emption Group's most recent Statement of Principles for the purposes of each of resolutions 17 and 18, nor are they proposing to provide specifically for follow-on offers, they intend to continue to review market practice.

If the powers sought by resolutions 19 and 20 are used in relation to a non-pre-emptive offer, the Directors confirm their intention to have regard to the shareholder protections in Part 2B of the Statement of Principles. While the resolutions do not specifically provide for follow-on offers, where relevant, the Directors confirm their intention to follow the expected features of a follow-on offer as set out in paragraph 3 of Part 2B of the Statement of Principles.

WPP NOTICE OF 2026 AGM

IMPORTANT NOTES

However you choose to participate, the AGM is a valuable opportunity for the Board to communicate directly with shareholders. The Company has determined to hold its AGM as a physical meeting and therefore shareholders (and their proxies) are welcome to attend in-person, should they wish to do so. As in previous years, we will also be offering shareholders the opportunity to follow the business of the AGM via a live webcast. This will allow shareholders to watch the presentations and ask questions during the Meeting, as they would if they were attending in-person. Please note that voting will not be possible via the live webcast. Further details on how you can join us virtually and ask questions are set out on page 13 of this Notice.

In-person admission is from 9.15am and light refreshments will be served after the Meeting.

Please note, if you are unable to attend the AGM on the day to vote in person, you are strongly encouraged to lodge a vote by proxy ahead of the Meeting.

Only shareholders whose names appear on the register of members of the Company at 10.00am on Wednesday 6 May 2026 or 48 hours before any adjourned meeting (excluding any day that is not a working day) shall be entitled to vote at the AGM in person or by proxy and the number of ordinary shares then registered in their respective names shall determine the number of votes such persons are entitled to cast at the Meeting. Changes to the register of members of the Company after the relevant deadline shall be disregarded in determining the rights of any person to attend and vote at the Meeting.
A shareholder entitled to vote at the Meeting may appoint one or more proxies to vote instead of him or her. A shareholder may appoint more than one proxy in relation to the Meeting provided that each proxy is appointed to exercise rights attached to a different share or shares held by him or her. A proxy need not be a shareholder of the Company. A proxy form (Form of Proxy) to appoint a proxy and give proxy instructions accompanies this Notice (if you received this Notice in the post) or see paragraph 5 to appoint your proxy and submit instructions online.
To be valid, the Form of Proxy for use at the Meeting and power of attorney or other authority, if any, under which it is signed or a notarially certified or office copy of such power or authority, must be received at the offices of Computershare Investor Services (Jersey) Limited, c/o The Pavilions, Bridgwater Road, Bristol BS99 6ZY, by 10.00am on Wednesday 6 May 2026 or not less than 48 hours before any adjourned meeting (excluding any day that is not a working day). Completion and return of the Form of Proxy, other such instrument or Crest Proxy Instruction (as described in note 7) will not prevent you from attending and voting at the Meeting instead of your proxy, if you wish to do so.
As an alternative to completing and returning the printed Form of Proxy, you may appoint your proxy and submit instructions online by 10.00am on Wednesday 6 May 2026 or not less than 48 hours before any adjourned meeting (excluding any day that is not a working day), by accessing the Company's website, wpp.com/investors/shareholder-centre/shareholder-meetings.

For security purposes, shareholders will need to provide their shareholder reference number (SRN), control number and personal identification number (PIN) to validate the submission of their proxy online. Shareholders' individual SRNs and PINs are shown on the printed Form of Proxy or email sent to them.

A person to whom this Notice is sent who is a person nominated to enjoy information rights (a Nominated Person) may, under an agreement between him/her and the shareholder by whom he/she was nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the AGM. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he/she may, under any such agreement, have a right to give instructions to the shareholder as to the exercise of voting rights. The statements of the rights of shareholders in relation to the appointment of proxies in paragraphs 3, 4 and 5 above and paragraph 7 below do not apply to a Nominated Person. The rights described in these paragraphs can only be exercised by registered members of the Company.
CREST members who wish to appoint a proxy or proxies by utilising the CREST electronic proxy appointment service may do so for the Meeting and any adjournment(s) thereof by utilising the procedures described in the CREST Manual, which is available on the Euroclear website. CREST personal members or other CREST sponsored members and those CREST members who have appointed a voting service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf.

In order for a proxy appointment made by means of CREST to be valid, the appropriate CREST message (a CREST Proxy Instruction) must be properly authenticated in accordance with Euroclear's specifications and must contain the information required for such instructions, as described in the CREST Manual. The message, whether it constitutes the appointment of the proxy or an amendment to the instruction given to a previously appointed proxy must, in order to be valid, be transmitted so as to be received by the issuer's agents, Computershare Investor Services (Jersey) Limited (ID3RA50), by no later than 10.00am on Wednesday 6 May 2026 or not less than 48 hours before any adjourned meeting (excluding any day that is not a working day). For this purpose, the time of receipt will be taken to be the time (as determined by the time stamp applied to the message by the CREST application's host) from which the issuer's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time, any amendment to the instruction given to a proxy appointed through CREST should be communicated to the proxy through other means.

CREST members and, where applicable, their CREST sponsors or voting service providers should note that Euroclear does not make available special procedures in CREST for any particular messages. Normal system timing and limitations will therefore apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member or sponsored member or has appointed a voting service provider(s) to procure that their CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members and, where applicable, their CREST sponsors or voting service providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timing.

The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Article 34 of the Companies (Uncertificated Securities) (Jersey) Order 1999.

WPP NOTICE OF 2026 AGM

If you are an institutional investor you may also be able to appoint a proxy electronically via the Proxymity platform, a process which has been agreed by the Company and approved by the Company's registrar. For further information regarding Proxymity, please go to www.proxymity.io. Your proxy must be lodged by 10.00am on Wednesday 6 May 2026 or not less than 48 hours before any adjourned meeting (excluding any day that is not a working day), in order to be considered valid. Before you can appoint a proxy via this process you will need to have agreed to Proxymity's associated terms and conditions. It is important that you read these carefully as you will be bound by them and they will govern the electronic appointment of your proxy.
If you return more than one proxy appointment in respect of the same share, either by paper or electronic communication, the appointment received last by the Company's registrar before the latest time for the receipt of proxies will take precedence.
If more than one of the joint holders of a share tenders a vote on the same resolution, whether in-person or by proxy, the vote of the senior who tenders a vote shall be accepted to the exclusion of the vote(s) of the other joint holder(s); and for this purpose seniority shall be determined by the order in which the names stand in the register in respect of the relevant share.
Any shareholder attending the AGM has the right to ask questions. There are three ways that shareholders can ask questions, either in advance, or at the Meeting:
pre-submitted questions: by emailing them to [email protected] by 10.00am on Wednesday 6 May 2026;
during the Meeting via the live webcast. For instructions on how to submit a question via the live webcast, please see page 13; and
in person at the Meeting.

To enable the Board to answer as many shareholder questions as possible, we encourage you to submit questions in advance and we will endeavour to respond to all questions emailed in advance at the Meeting.

Answers to common questions submitted in advance by email and a transcript of all the questions asked and answered during the AGM will be published on our website at wpp.com/investors following the conclusion of the AGM. Shareholders may also use the above email address shortly after the Meeting to follow up on any answers given to questions.

Following the Meeting, shareholders will be able to access details of the business conducted at the AGM (including responses to questions and any presentation materials) on our website: wpp.com/investors. The Chair of the Meeting will ensure that any question relating to the business being dealt with at the AGM receives a response, but no response shall be given if: (i) to do so would interfere unduly with the business of the Meeting or involve the disclosure of confidential information; (ii) the answer has already been given on the Company's website, wpp.com, in the form of an answer to a question; or (iii) the Chair of the Meeting determines that it is undesirable in the interests of the Company or the good order of the AGM that the question be answered. Please also be advised that unacceptable behaviour – including in relation to language, disruption to the Meeting and line of questioning adopted during Q&A sessions, will not be tolerated at the Meeting and will be dealt with accordingly by the Chair of the Meeting.

As at 12 March 2026 (being the latest practicable date prior to publication of this Notice) the Company's issued share capital consists of 1,091,394,251 ordinary shares carrying one vote each of which 12,591,893 shares are held in treasury.

Therefore, the total voting rights in the Company as at 12 March 2026 are 1,078,802,358.

Any body corporate which is a member of the Company can authorise one or more persons to act as its representative at any general meeting of the Company. Where more than one person is authorised to represent a body corporate and more than one person purports to exercise a power on behalf of that body corporate, the power will not be treated as exercised if each such person does not purport to exercise the power in the same way.

SHAREHOLDER SECURITY

We are aware that some of our shareholders have received unsolicited and suspicious phone calls or mail from purported 'brokers' who offer to buy their shares at a price far in excess of their market value. It is unlikely that firms authorised by the Financial Conduct Authority (FCA) will contact you with offers like this. As such, we believe these calls are part of a scam, commonly referred to as a 'boiler room'. The callers obtain your details from publicly available sources of information, including the Company's share register. The callers can be very persistent and persuasive and it is not just the novice investor that has been tricked in this way.

Shareholders are advised to be very wary of any unsolicited advice, offers to buy shares at a discount, sell shares at a premium, incentives to participate in 'green' or carbon reduction projects, offers of free company reports or requests to complete confidentiality agreements with the caller. Check the firm on the FS register at www.fca.org.uk/register. The Financial Services Register is a public record of all the firms and individuals in the financial services industry that are regulated by the Financial Conduct Authority (FCA).

ASKING QUESTIONS VIA WEBCAST

Shareholders may ask questions via the live webcast by typing and submitting their question in writing. To ask a question, you should select the 'Ask a question' tab from within the navigation bar at the top right corner of the screen to open the message box and type your question. Once finished, press the 'Submit' button to the right of the message box to submit your question. Select 'Slides' tab within the navigation bar to return to the AGM presentation.

Questions sent via the 'Ask a question' box on the live webcast will not be visible to any other attendees and will be moderated before being sent to the Chair of the Meeting.

TECHNICAL SUPPORT
