1 WPP PLC DEALING CODE Effective on 3 July 2016 Updated March 2021 Introduction The purpose of this code is to ensure that the directors of WPP plc (the “Company”), and certain employees of the Company and its subsidiaries, do not abuse, and do not place themselves under suspicion of abusing, Inside Information and comply with their obligations under the Market Abuse Regulation. Part A of this code contains the Dealing clearance procedures which must be observed by the Company’s Directors and those employees who have been told that the clearance procedures apply to them. This means that there will be certain times when such persons cannot Deal in Company Securities. Part B sets out certain additional obligations which only apply to WPP plc directors. Failure by any person who is subject to this code to observe and comply with its requirements may result in disciplinary action. Depending on the circumstances, such non-compliance may also constitute a civil and/or criminal offence. Schedule 1 sets out the meaning of capitalised words used in this code. Part A – Clearance procedures 1. Clearance to Deal 1.1 You must not Deal for yourself or for anyone else, directly or indirectly, in Company Securities without obtaining clearance from the Company in advance. 1.2 Applications for clearance to Deal must be made in writing and submitted to the Company Secretary using the form set out in Schedule 2, unless paragraph 1.8 applies. 1.3 You must not submit an application for clearance to Deal if you are in possession of Inside Information. If you become aware that you are or may be in possession of Inside Information after you submit an application, you must inform the Company Secretary as soon as possible and you must refrain from Dealing (even if you have been given clearance). 1.4 You will receive a written response to your application, normally within three working days. The Company will not normally give you reasons if you are refused permission to Deal. You must keep any refusal confidential and not discuss it with any other person. You will not receive a written response where the Dealing is being carried out by the Company in relation to an employee share plan, as referred to in paragraph 1.8.

2 1.5 If you are given clearance, you must Deal as soon as possible and in any event within two working days of receiving clearance. 1.6 Clearance to Deal may be given subject to conditions. Where this is the case, you must observe those conditions when Dealing. 1.7 You must not enter into, amend or cancel a Trading Plan or an Investment Programme under which Company Securities may be purchased or sold unless clearance has been given to do so. 1.8 Different clearance procedures will apply where Dealing is being carried out by the Company in relation to an employee share plan (e.g. if the Company is making an option grant or share award to you, or shares are receivable on vesting under a long-term incentive plan). You will be notified separately of any arrangements for clearance if this applies to you. 1.9 If you act as the trustee of a trust, you should speak to the Company Secretary about your obligations in respect of any Dealing in Company Securities carried out by the trustee(s) of that trust. 1.10 You should seek further guidance from the Company Secretary before transacting in: (A) units or shares in a collective investment undertaking (e.g. a UCITS or an Alternative Investment Fund) which holds, or might hold, Company Securities; or (B) financial instruments which provide exposure to a portfolio of assets which has, or may have, an exposure to Company Securities. This is the case even if you do not intend to transact in Company Securities by making the relevant investment. 2. Further guidance If you are uncertain as to whether or not a particular transaction requires clearance, you must obtain guidance from the Company Secretary before carrying out that transaction. Part B – Additional provisions for WPP plc Directors 3. Circumstances for refusal You will not ordinarily be given clearance to Deal in Company Securities during any period when there exists any matter which constitutes Inside Information or during a Closed Period.

3 4. Notification of transactions 4.1 You must notify the Company and the FCA in writing of every Notifiable Transaction in Company Securities conducted for your account as follows: (A) Notifications to the Company must be made using the template in Schedule 3 and sent to the Company Secretary as soon as practicable and in any event within one working day of the transaction date. You should ensure that your investment managers (whether discretionary or not) notify you of any Notifiable Transactions conducted on your behalf promptly so as to allow you to notify the Company within this time frame. (B) Notifications to the FCA must be made within two working days of the transaction date. If you would like, the Company Secretary can assist you with this notification, provided that you ask him or her to do so within one working day of the transaction date. 4.2 If you are uncertain as to whether or not a particular transaction is a Notifiable Transaction, you must obtain guidance from the Company Secretary. 5. PCAs and investment managers 5.1 You must provide the Company with a list of your PCAs and notify the Company of any changes that need to be made to that list. 5.2 You should ask your PCAs not to Deal (whether directly or through an investment manager) in Company Securities during Closed Periods. 5.3 Your PCAs are also required to notify the Company and the FCA in writing, within the time frames given in paragraph 4.1, of every Notifiable Transaction conducted for their account. You should inform your PCAs in writing of this requirement and keep a copy; the Company Secretary will provide you with a letter that you can use to do this. If your PCAs would like, the Company Secretary can assist them with the notification to the FCA, provided that your PCA asks the Company Secretary to do so within one working day of the transaction date. 5.4 You should ask your investment managers (whether or not discretionary) not to Deal in Company Securities on your behalf during Closed Periods.
