("Tristel" or the "Company")

Result of AGM

Tristel plc (AIM: TSTL), the manufacturer of infection prevention products, announces that at the Annual General Meeting ("AGM") held earlier today, all resolutions were duly passed.

Resolution 1, which sought to receive and adopt the Company's annual accounts for the financial year ended 30 June 2025, together with the Directors' report, the Directors' remuneration report and the auditor's report on those accounts, passed with 59% of votes cast. With respect to this resolution the Company received notice from one of the proxy voting advisers that they were recommending investors to vote against it, due to lack of a separate vote for remuneration policy and the level of loss of office payment to a former Director accompanied by limited disclosure.

Resolution 1 has been discussed with several of the institutional shareholders and within the Board. The Board undertakes that it will ensure any necessary future disclosure complies with best practice, along with committing to put the remuneration policy to a separate vote at future AGMs, in line with QCA guidance.

The Company would like to reiterate that it takes its shareholder responsibilities seriously and has a clear focus on striving for governance best practice, sharpening capital allocation and driving sustainable growth.

The results of the AGM will be made available on the Company's website: https://tristelgroup.com/invest/annual-general-meeting-agm/
