Elementis plc

Result of 2025 AGM

The Company's AGM was held today (29 April 2025) at the offices of A&O Shearman LLP, One Bishops Square, London, E1 6AD and all resolutions proposed were passed on a poll.

For information, the following table shows the poll results for the Meeting. The total number of shares in issue (ISC) as at 25 April 2024 was 592,396,347. (Total voting rights: 592,396,347). The percentage figure shown in each column is the percentage of the total number of votes validly cast (under law) for each resolution (i.e. excludes votes withheld).

*     Resolutions 19 to 22 were passed as special resolutions.

The Board notes that all resolutions were passed at today's AGM and thanks shareholders for their engagement and support. The Board notes that 24.01% of the votes cast in relation to Resolution 6 (to elect Christopher Mills as a director) were against the resolution. The Board understands that this is due to one of the proxy agents having recommended a vote against Christopher Mills' election due to perceived overboarding, based on the criteria used by that proxy agent. The views of shareholders are important to the Board, and the Chair will engage with the shareholders who voted against this resolution to consider any feedback received in relation to this result.

In accordance with Listing Rule 9.6, copies of the resolutions, designated as being special business, passed at the AGM will be submitted to the National Storage Mechanism and will be available shortly for inspection at: https://data.fca.org.uk/#/nsm/nationalstoragemechanism

These voting results will also be available on the Company's website at https://www.elementis.com/investors/shareholder-information/annual-general-meeting/ later this afternoon.
