Microsaic Systems plc

("Microsaic" or the "Company")

FY22 Annual Report and Accounts

Further to the Company's announcement on 26 June 2023 (the "Prior Announcement"), the Board of Microsaic (AIM: MSYS) now confirms that the Company's annual report and accounts for the year ended 31 December 2022 ("FY22") will not be published by 30 June 2023, being the deadline for publication under the AIM Rules for Companies.  Consequently, the Company's shares will be suspended from trading on AIM with effect from 3 July 2023, pending publication of the FY22 annual report and accounts.

The Board noted in the Prior Announcement that, as of 31 May 2023, Microsaic had £0.65m in cash and on deposit, with no bank borrowings. The Company also stated that it continues to meet its obligations as they fall due. In light of the challenges associated with making further recovery of the outstanding debtor balance from DeepVerge plc, and that  the conversion of its growing pipeline and the speed and scale of revenue generation are uncertain, the Prior Announcement noted that it was likely that Microsaic will need to raise further working capital during Q3 2023.

The Company confirms that it is working to that end and intends to conclude a fundraising within that period, and to seek reinstatement of its shares to trading on AIM shortly aftewards, subject also to having published the FY22 report and accounts on a going concern basis. Such fundraising is likely to be subject to shareholder approval to issue and allot new shares.

Further announcements will be made as appropriate.
