Vote online now - submit your proxy instruction no later than 2pm (UK time) on Monday 27 April 2026

We encourage all our shareholders to vote online. Voting online is the best way to make sure your vote is registered on time.

Visit shareview.co.uk – it's easy, fast and secure.

If you send in your paper voting form and fill in one online, we'll count the instruction we receive last.

You can still attend and vote at the meeting in person. Please refer to Step 5 below.

Visit aberdeenplc.com/agm for more information.

Your voting form – return no later than 2pm (UK time) on Monday 27 April 2026

Please use black ink and block capitals to complete this form.

Your voting form can't be transferred between shareholders – it can only be used by you.

Step 1 – Vote on the resolutions

Please cross (x) one box for each resolution. Any other mark in a box will count as a cross.

The Board recommends you vote 'For' all the resolutions as it considers them to be in the best interests of the Company and shareholders as a whole.

If you don't give instructions on how to vote on a resolution, the person appointed to vote for you can vote on it as they think fit. If any other business takes place at the meeting, or at any adjournment, they can vote (or not vote) on that business as they think fit.

Step 2 – Sign and date the form

You must sign in the signature box and insert the date on the other side of this form.

Signing under a power of attorney? Make sure you enclose an original or a certified copy of the power of attorney with your voting form.

Signing on behalf of a company? You must be a duly appointed officer or agent of the company and write the capacity in which you are signing below the signature box.

The Notice of Meeting explains more about using this form for companies and for shareholders who are unable to manage their own affairs.

Step 3 – Nominating a proxy

If you sign overleaf and do not write a name in the 'Nominating a proxy' box, you instruct the chair of the meeting to attend and vote in your name at the annual general meeting on Wednesday 29 April 2026 and at any adjournment.

Most people choose the chair of the meeting to vote on their behalf if they do not wish to attend the annual general meeting in person. If you prefer, you can appoint someone else to attend the meeting and vote on your behalf.

A nominated proxy does not need to be a shareholder of Aberdeen Group plc. Whoever it is will only be able to vote on your behalf by attending the meeting. If your nominated proxy isn't there, your vote will not count. A nominated proxy is entitled to speak and can vote on a poll. If you would like to appoint a nominated proxy to vote for you,

please write their full name in the 'Nominating a proxy' box on the other side of this form.

If you want to appoint more than one person to attend the meeting and vote on your behalf, you'll need to complete additional paper voting forms. Contact Equiniti to ask for these, or just photocopy this form. On each form, write the name of a nominated proxy. In the box next to their name, write the number of shares for which they are to be authorised to act as proxy on your behalf. If you don't write a number, we'll assume your instructions to your proxy relate to all your shares in the account which your voting form is for.

To tell us that your instruction is one of multiple instructions you are giving, put a cross (x) in the box beneath the 'Nominating a proxy' box. You must sign and date all the forms and should return them in the same envelope.

Step 4 – Return your form

Send your voting form in the pre-paid envelope provided. You can also deliver your form by hand or send it to Equiniti, Aspect House, Spencer Road, Lancing, West Sussex BN99 6DA. If you want to ensure we receive your instructions, you should use your own envelope and send it to the address above using a tracked or signed for service, or go online.

If your voting form arrives after 2pm (UK time) on Monday 27 April 2026, it will not count.

Step 5 – Coming to the meeting?

Shareholders can attend the meeting in person. If you want to attend the meeting in person, please still send us your voting form. If you send us your voting form and vote at the meeting, it will be your vote at the meeting that counts.

Please bring your letter from the Chairman and some other form of identification with you.

Shareholders planning to attend the meeting should refer to the Notice of Meeting for details of the attendance arrangements. The Notice of Meeting can be found at aberdeenplc.com/agm
