Introduction
RHIM has successfully held virtual AGMs since 2020, which enabled greater attendance and access to the AGM. AGMs since 2023 have been convened as hybrid meetings and the 2026 AGM has also been convened as a hybrid meeting in order to continue to offer shareholders the ease and convenience of virtual participation.
The Directors will join the meeting virtually and there will be limited presence in the Netherlands. This is in order to make the AGM as efficient and cost-effective as possible, whilst still ensuring the access and rights of shareholders. Furthermore, it reduces the Company's impact on the environment.
Please ensure you login from 30 minutes before the AGM starts. If you join after the start of the meeting, you will be allowed guest entrance to watch the webcast, but not the ability to vote or submit questions.
Shareholders will not be on video nor able to be heard.
Please note, throughout this document 'shareholder' is used to indicate shareholders or depositary interest holders.

Q: How can I register to participate electronically as a shareholder at the AGM?A: As an RHI Magnesita shareholder, you will need to register before 6 May 2026 at 14:00 (CET) to attend the meeting as outlined in the instructions in the Notice of Meeting
Q: Where can I login to participate electronically in the AGM as a shareholder?A: Via web.lumiagm.com.
Q: I have already registered for online participation in the AGM, but now I would like to participate in person. Is that possible?A: We would not recommend participation in person as we believe that a virtual AGM preserves the rights and access of shareholders to the Board, whilst reducing travel time, impact on environment and the costs of an in-person AGM. We would therefore encourage virtual participation. Changing your attendance to be in person is technically possible, providing you have notified of your intention to do so by 6 May 2026 at 14:00 CET. This will override your online participation.
Q: I have already registered for online participation at the AGM, but now I would like to participate through a proxy. Is that possible?A: You can change to nominate a proxy as long as this is submitted before 6 May 2026 14:00 CET.
Frequently asked questions - registration process
Q: When can I login to the AGM?A: You can login from 30 minutes before the start of the meeting. Once you have done so you are counted as a shareholder attending the meeting, even if you leave before the start of or any time during the meeting (whether or not due to an internet connection failure). If you join after the start of the meeting, you will be allowed guest entrance to watch the webcast but will not have the ability to vote or submit questions.
Q: Can I follow/participate in the AGM if I'm not a shareholder?
A: The Company may permit guests to attend at its discretion. Should you wish to join the webcast as a guest please email companysecretary@RHIMagnesita.com and further details will be provided. Please note any attendance needs to be registered by 6 May 2026 at 14:00 CET.
Q: How do I know that I can vote during the AGM?A: Once the Chair of the meeting has opened the AGM and advised that the voting is open, you will be able to vote until the Chair declares that the voting will be closed, after the last voting item. The application will confirm that your vote(s) has/have been received, as shown in example on slide 9 of this guidance.
Frequently asked questions - shareholder meeting
Q: Can I ask questions in the AGM?A: Yes, shareholders are requested to submit their questions by 11 May 2026 at 14:00 CET (see the AGM Notice) to facilitate a smooth meeting. To submit questions or any comments during the AGM, you can click on the Q&A icon. All Q&A will be published on the website following the meeting.
Q: Can I also vote in advance of the AGM?A: Yes, you can by giving a proxy voting instruction via the instructions on the Notice of Meeting. We would recommend this as the easiest and most effective route for voting.
Q: I have already voted via a proxy, do I need to vote again?A: No, your proxy voting instruction will remain valid.
Q: I have already voted via a proxy, can I change my vote during the AGM?A: If you grant a proxy voting instruction your vote has, in fact, effectively been made before the meeting takes place and you will only be able to change your voting instruction up until 14:00 CET, 5 May 2026.

Frequently asked questions - general questions
Q: I don't have a smartphone, tablet or PC. Will I be able to participate in the AGM?A: Use of a smartphone, PC, or tablet is required to participate. If you do not have access to one, we recommend that you submit your votes by proxy in advance, or attend in person, as you will not be able to attend virtually.

Q: If there's a failure in my network connection, or my device stops working during the AGM will I be able to login and continue to participate in the AGM once the connection has been restored?A: Yes, assuming you have logged in successfully prior to the start of the AGM, you will be able to continue participating in the AGM after the network connection has been restored. You will also be able to vote on items that have been put to vote in the meantime. The polls for all items are open during the AGM and closed after the last voting item on the agenda has been discussed.
Q: My battery is almost empty. What do I do?A: The shareholder is responsible for a properly functioning and charged device.
Frequently asked questions - general questions
Q: The device that I will use for online participation has a camera installed: will, or can, I be made visible in the AGM to other participants or anyone else?A: No, that will not be the case. You will be able to see the Board of Directors, the Chair of the AGM and the Company Secretary.
Q: I appreciate the possibility to participate online at the AGM but how can RHI Magnesita ensure that online participation will be without issues?A: The application RHI Magnesita offers has been used for a number of shareholder meetings in the Netherlands since the outbreak of COVID-19. It has been successfully used in our AGMs since 2020.
RHI Magnesita offers the application through third parties who have substantial experience in organising and hosting virtual and hybrid shareholder meetings in the Netherlands. However, even though RHI Magnesita has made every effort to ensure that shareholders are offered a best-in-market service, it cannot guarantee that shareholders do not experience issues that are common to any first-generation, innovative application. If you are worried, you should submit your vote via proxy in advance. You will still be able to attend the meeting and ask questions and see the webcast, in the same way as for our previous AGMs.
Frequently asked questions - exercise of rights
Q: Are my votes valid when leaving early? Can I re-join after I have left?A: Yes, assuming you have logged in successfully prior to the start of the meeting this will not affect the votes cast up until the moment you left. Re-joining the meeting after you've left is possible and you will also be able to vote upon items that have been put to vote in the meantime. The polls for all items are open during the AGM and closed after the last voting item on the agenda has been discussed.
Q: I have registered for online participation but have subsequently sold my shares. Can I still vote on these shares?A: Yes, according to Dutch law the 28th day before the day of the AGM is decisive for who will be able to vote. As registration is only possible after that record date (15 April 2026), the right to vote remains even if you have already sold your shares in the meantime.
Q: Will the possibility of online participation affect the proceedings at the AGM?A: At the AGM the usual proceedings for general meetings of RHI Magnesita will be followed. There will be more time allowed for voting on items compared to a fully physical meeting; the polls for all items are open from the start of the business of AGM and will close after the last voting item on the agenda has been discussed.
