Update re. Publication of
Annual Report & Accounts

Further to the announcement made on 19 June 2024, Microsaic Systems plc (AIM: MSYS), the developer of micro-electronic instruments and provider of integrated analytical water testing solutions, provides an update on the expected publication date of its annual report and accounts for the year to 31 December 2023 (the "FY23 Accounts").

The Company continues to work with its auditors to complete the audit of the FY23 Accounts, which is progressing more slowly than expected due to unforeseen difficulties in the handover of prior year information between the former and current finance teams. The board have ensured strong financial and governance controls have remained effective throughout this transition. The Company will therefore not be in a position to publish the FY23 Accounts before the end of July 2024 as previously notified. As a result, trading in the Company's ordinary shares on AIM will continue to be suspended pending the publication of the FY23 Accounts.

Notwithstanding the temporary suspension of trading in the Company's ordinary shares, the Company will continue to make announcements as and when there are developments that require announcement in accordance with its obligations under the AIM Rules for Companies.
