NOTICE OF 2023 ANNUAL GENERAL MEETING

In accordance with Listing Rule 9.6.1, RHI Magnesita N.V. (LSE: RHIM) has submitted today the Notice of the 2023 Annual General Meeting (the "AGM Notice") to the National Storage Mechanism.

Given the successful virtual meetings since 2020, RHI Magnesita is enabling shareholders to attend and participate electronically again in 2023 and the AGM will be webcast as a hybrid meeting. Pursuant to Dutch law, there will be a physical presence at the Linklaters office in Amsterdam, but the Directors will be joining via webcast from their respective locations. A hybrid meeting will reduce costs and the environmental impact from air travel, whilst still providing open and direct contact with the Board for shareholders. 

More details can be found in the explanatory notes to the AGM Notice and in the AGM area of our Company website. Shareholders are invited to submit questions in advance and will be able to attend and vote in the AGM via webcast.

The AGM Notice will shortly be available for inspection at https://data.fca.org.uk/#/nsm/nationalstoragemechanism

A copy of the AGM Notice is available through the 'Investors' page within our website www.rhimagnesita.com.
