Notes to the Form of Proxy

1. As a member of Mondi plc you are entitled to appoint a proxy to exercise all or any of your rights to attend, speak and vote at the Annual General Meeting of Mondi plc. Each resolution is to be decided on a poll and a member or proxy shall have one vote for every share held. You can only appoint a proxy using the procedures set out in these notes. Full details of the resolutions to be proposed at the Annual General Meeting, with explanatory notes, are set out in the notice of Annual General Meeting.
1. Appointment of a proxy does not preclude you from attending the meeting and voting. If you have appointed a proxy and attend the meeting your proxy appointment will automatically be terminated.
1. A proxy does not need to be a member of Mondi plc but must attend the meeting to represent you. To appoint as your proxy a person other than the chair of the meeting, insert their full name in the box. If you sign and return this proxy form with no name inserted in the box, the chair of the meeting will be deemed to be your proxy. Where you appoint as your proxy someone other than the chair, you are responsible for ensuring that they attend the meeting and are aware of your voting intentions. If you wish your proxy to make any comments on your behalf, you will need to appoint someone other than the chair and give them the relevant instructions directly.
1. You may appoint more than one proxy provided each proxy is appointed to exercise rights attached to different shares. You may not appoint more than one proxy to exercise rights attached to any one share. To appoint more than one proxy, (an) additional form(s) may be obtained by visiting Equiniti's website at www.shareview.co.uk. Please indicate in the box provided 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 the proxy instruction is one of multiple instructions being given. All forms must be signed and should be returned together.
1. To direct your proxy how to vote on the resolutions mark the appropriate box with an 'X'. To abstain from voting on a resolution, select the relevant 'Vote Withheld' box. A vote withheld is not a vote in law, which means that the vote will not be counted in the calculation of votes for or against the resolution. If no voting indication is given, your proxy will vote or abstain from voting at their discretion. Your proxy will vote (or abstain from voting) as they think fit in relation to any other matter which is properly put before the meeting.
1. To appoint a proxy using this form, the form must be:
2. completed and signed;
3. sent or delivered to Equiniti, Aspect House, Spencer Road, Lancing, West Sussex, BN99 6DA, United Kingdom; and
4. received by Equiniti no later than 10:30 (UK time) on Tuesday 6 May 2025.

Please return the proxy form in the enclosed envelope.

Seniority is determined by the order in which the names of the joint holders appear in Mondi plc's register of members in respect of the joint holding (the first-named being the most senior).
1. If you submit more than one valid proxy appointment, the appointment received last before the latest time for the receipt of proxies will take precedence.
