Notes to the Form of Proxy:

• (i) Every holder of ordinary shares is entitled to appoint as his/her/their proxy another person, who need not be a shareholder of the Company, to exercise all or any of his/her/their rights to attend, speak and vote at the meeting. Shareholders are permitted to restrict the rights of proxies. If you wish to restrict the rights of your proxy, please cross out either or both of the words 'speak' or 'vote' on the Form of Proxy as you deem appropriate. For convenience, the appointment of the Chair of the AGM has already been included. If the proxy is being appointed in relation to less than your full voting entitlement, please enter in the box next to the proxy holder's name (see reverse) the number of ordinary shares in relation to which they are authorised to act as your proxy. If left blank, your proxy will be deemed to be authorised in respect of your full voting entitlement. Unless you give specific instructions on how to vote on a particular resolution, your proxy may vote as he or she thinks fit.
• (ii) To appoint more than one person as your proxy, you may photocopy the Form of Proxy in relation to each proxy you wish to appoint, provided that each proxy is appointed to exercise the rights attaching to a different share or shares held by you. Each Form should clearly indicate the name of the proxy (see reverse), and the number of ordinary shares in relation to which they are authorised to act as your proxy. Please also indicate if the proxy instruction is one of multiple instructions being given. The Chair of the AGM may be appointed as one of your multiple proxies provided you follow the instructions set out in this Form. All Forms must be signed and should be returned together in the same envelope.
• (iii) The 'Vote withheld' option is provided to enable you to abstain from voting on any particular resolution. However, it should be noted that a 'Vote withheld' is not a vote in law and will not be counted in the calculation of the proportion of the votes 'For' and 'Against' a resolution.
• (iv) To be valid this Form must be signed and received by Link Group no later than 11:00 am on Tuesday 10 May 2022. Only the first named joint holder need sign the Form. If the holder is a corporation, the Form must show the company's common seal, or be signed on its behalf by an attorney or officer stating their capacity (e.g. director or secretary). Any power of attorney or other authority under which this Form of Proxy is signed (or a certified copy of such power or authority) must be included with this Form of Proxy.
• (v) UK shareholders should reply by posting their Form of Proxy to Link Group in the envelope provided. No stamp is required. Shareholders with addresses outside the UK should reply by posting their Form of Proxy in an envelope to: Link Group, PXS, 10th Floor, Central Square, 29 Wellington Street, Leeds LS1 4DL, United Kingdom.
• (vi) Shares held in uncertificated form (i.e. CREST) may be voted through the CREST Proxy Voting Service in accordance with the procedures set out in the CREST Manual and in the Notice of AGM.

eShareholder programme – your choice

An increasing number of shareholders now recognise the urgent need to reduce the environmental impact and associated costs of printing and posting shareholder documents such as the Notice of AGM.

Our eShareholder programme, where we use electronic and website communication, provides you with easy and convenient access to shareholder documents. It also saves paper and postage which helps us limit our environmental impact and reduce costs.

The Balfour Beatty Share Portal at www.balfourbeatty-shares.com enables you to access the full range of online shareholder services, including the ability to: view your holdings and indicative share price and valuation; view movements on your holdings and your dividend payment history; register a dividend mandate to have your dividends paid directly into your bank account; (for shareholders outside the UK) elect to receive dividends paid directly into your overseas bank account, or by currency draft, instead of by sterling cheque; change your registered address; sign up to receive electronic shareholder communications or access the online proxy voting facility; and download and print shareholder forms. It is easy to use.

You can choose from the options set out in the shareholder communication election form below. Where possible, we encourage shareholders to receive notifications from us by email which would reduce our environmental impact and costs.

We have a clear vision for operating sustainably, with specific goals. You will find evidence of this throughout our Annual Report and Accounts 2021 and by visiting our website at www.balfourbeatty.com/sustainability.
