Notes: Completing your Proxy Card

• Whether or not you intend to attend the meeting in person or electronically, we strongly encourage you to appoint the Chair, as opposed to any other person, to act as your proxy to ensure your vote is counted (if, for instance, you or that other person are not able to attend the meeting in person or electronically). If the Chair is appointed as your proxy, he or she will vote in accordance with any instructions given to him or her; if he or she is given discretion as to how to vote, the Chair will vote in line with the Board's recommendation on all of the resolutions to be proposed at the AGM.
• To appoint someone other than the Chair as your proxy, write their name in the space provided. Please note, if you appoint someone other than the Chair as your proxy, you are responsible for ensuring that they attend the meeting and know how you wish to vote. If you or your proxy do not attend, your votes will not be cast.
• If your proxy is being appointed in relation to less than your full voting entitlement, please enter the number of shares in relation to which they are authorised to act as your proxy in the space provided. If left blank, your proxy will be deemed to be authorised in respect of your full voting entitlement (or if this Proxy Card has been issued in respect of a designated account for a shareholder, the full voting entitlement for that designated account).
• To appoint more than one proxy, you may photocopy this Proxy Card. Please indicate the proxy holder's name and the number of shares in relation to which they are authorised to act as your proxy (which, in aggregate, should not exceed the number of shares held by you). Please also indicate if the proxy instruction is one of multiple instructions being given by ticking the relevant box. All Proxy Cards must be signed and should be returned together in the same envelope. You must indicate the number of shares each proxy is authorised to act as your proxy on for your proxy to be valid.
• Place an X in black ink in the box where indicated showing how you wish to vote for each resolution. If you do not mark a resolution, your proxy can decide how to vote or decide to withhold your vote on that resolution and on any other business which may validly come before the AGM.
• Sign and date the Proxy Card in the spaces provided. Where shares are held in joint names, only one shareholder needs to sign. If the shareholder is a corporation, the form must be executed under its common seal or signed by an officer, attorney or other person duly authorised by the corporation.
• Any alterations to this Proxy Card should be initialled.
• Any power of attorney or other formal authority (if any) that has not already been lodged with Equiniti and under which the Proxy Card is signed, or a copy of such power or authority certified by a notary, must accompany the Proxy Card.
• Once completed, return the Proxy Card in the envelope provided (which is pre-paid in the UK) to Equiniti. To be valid, Proxy Cards must be received by 11.00am on Thursday 6 July 2023.

• The address to which Proxy Cards should be sent is: Equiniti, Aspect House, Spencer Road, Lancing, West Sussex BN99 6DA. Postage will be payable if the pre-paid envelope provided is not used.

• You can submit your proxy instructions electronically, rather than by returning your Proxy Card, at sharevote.co.uk by no later than 11.00am on Thursday 6 July 2023.

• Shareholders should note that while the number of votes withheld will be counted and reported with other votes, votes withheld have no legal effect and only votes for and against will be counted when deciding the outcome of polls.
• Only registered shareholders can appoint a proxy. If you have received this as a person nominated to receive copies of the Company's communications, the proxy rights do not apply to you. You may have a right under an agreement with the registered shareholder to be appointed (or have someone else appointed) as a proxy for the AGM and you are advised to contact them.

Please note that proxy votes can only be submitted via paper Proxy Cards returned to the address stated, or electronically via sharevote.co.uk, shareview.co.uk, CREST or Proxymity.

Proxy votes cannot be submitted via any other means of communication, unless expressly permitted by National Grid or Equiniti.
