By accepting to receive shareholder communications via our website, or by registering to receive email communications, you would be helping us to reduce the environmental impact of our activities and assisting us in managing our printing and postage costs.

	Action required
An email from the Company, notifying you of where to find the communication online	Register online for Shareview at www.shareview.co.uk
Written notification of where to find a communication online	Do nothing
Paper copy of communications	Tick this box and return this form in the reply paid envelope provided
	What you will receive

11 April 2024

Dear Shareholder

With environmental and cost issues in mind, and given the ever growing size of the Annual Report due to the increasing number of regulatory disclosures, we are writing to ask whether you wish to continue to receive hard copy communications from us, or whether in future you would prefer to receive an email or website notification explaining where you can find the relevant documents online.

Please select your preference as set out in "Shareholder Communications – Your Choice" below and take the relevant action required.

You may wish to note that if you opt to receive "website communication" (or choose to take no action), you would currently receive, for this AGM communication, a document similar to the enclosed Notification of BAE Systems plc Annual Report 2023 and AGM which would direct you to our AGM website to view the full Annual Report and AGM Notice, and to vote on the resolutions.

Yours sincerely

David Parkes Company Secretary

BAE Systems plc Registered in England & Wales No. 1470151 6 Carlton Gardens, London SW1Y 5AD

Notes for completion of the Form of Proxy

• 1. This Form of Proxy is only for the use of Ordinary Shareholders and/or Ordinary Shareholders who hold their shares in BAE Systems plc via SHAREport (Equiniti Corporate Nominees Limited) ("the Nominee"). Where shares are held via SHAREport, references on this card to "Form of Proxy" should be read as "Form of Direction".
• 1. If you wish to appoint someone other than the Chair of the Meeting as your proxy, you may delete the reference to the Chair, and insert in block letters the name of the person you wish to appoint in the space provided and initial the alteration. A proxy need not be a member of the Company.

If the proxy is being appointed in relation to less than your full voting entitlement, please enter in the box entitled "Number of shares over which the proxy is appointed" the number of 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.

• 1. You may appoint more than one proxy, who may be the same person, provided each proxy is appointed to exercise rights attached to different shares. To do so you should photocopy the proxy form and indicate in the box entitled "Number of shares over which the proxy is appointed" the number of shares in relation to which they are authorised to act as your proxy. Please also indicate by ticking the box provided if more than one proxy is being appointed. All forms must be signed and should be returned together in the same envelope.
• 1. Please indicate how you wish your proxy to vote or if you wish them to abstain from voting by placing an 'X' in the appropriate boxes. In the absence of instructions the proxy or proxies may vote or abstain from voting the shares with respect to which he or she has been appointed as he or she thinks fit on both: (i) the resolutions specified overleaf; and (ii) on any other business or matter (including amendments to resolutions and procedural resolutions) which may come before the meeting.
• 1. The 'Vote Withheld' option overleaf is provided to enable you or your proxy to abstain 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 votes 'For' and 'Against' a resolution.
• 1. If the appointor is a corporation, the Form of Proxy must be under its common seal or under the hand of an officer or attorney duly authorised in writing. For further information on voting by corporate representatives, please see the 2024 AGM Notice of Meeting.
• 1. In the case of joint holders the signature of any one of them will suffice.
• 1. To be effective the completed and signed Form of Proxy, together with the power of attorney or other authority (if any) under which it is signed or a duly certified copy thereof, must be lodged at the office of the Company's Registrar, Equiniti, Aspect House, Spencer Road, Lancing BN99 6DA no later than 9.30am UK time on 7 May 2024.
• 1. If the card is posted in the UK, IOM or Channel Islands there is no postage to pay. Please use the reply-paid envelope provided.
• 1. If the card is posted from outside the UK, IOM or Channel Islands, please place it in an envelope, address it to: Equiniti, Aspect House, Spencer Road, Lancing BN99 6DA, United Kingdom, and affix the relevant postage so as to be received no later than 9.30am UK time on 7 May 2024.
• 1. You may register proxy appointments electronically by logging onto www.sharevote.co.uk and using the Voting ID, Task ID and Shareholder Reference Number given overleaf. If you are a CREST member you may also register proxies electronically by using the procedures described in the CREST Manual (Issuer's agent ID: RA19). Electronic proxy appointments will not be accepted unless received by 9.30am UK time on 7 May 2024.
• 1. The Company, pursuant to Regulation 41 of the Uncertificated Securities Regulations 2001, specifies that only those Ordinary Shareholders registered in the Register of Members of the Company as at 6.30pm on 7 May 2024 shall be entitled to attend or vote at the Annual General Meeting in respect of the number of shares registered in their name at that time. Changes to entries on the share register after 6.30pm on 7 May 2024 shall be disregarded in determining the rights of any person to attend and vote at the meeting.

How to use the Form of Proxy
