Publication of accounts and temporary suspension

Byotrol plc

PUBLICATION OF AUDITED RESULTS

FOR THE YEAR ENDED 31 MARCH 2019

TEMPORARY SUSPENSION OF TRADING IN SHARES FROM 1 OCTOBER

Byotrol plc ("Byotrol" or "the Company") has today released its Unaudited Preliminary Results for the year to 31 March 2019, which show good progress over the year.

Whilst the Directors are confident in the Unaudited Preliminary Results announcement and believe the statements are close to final form, those statements still remain subject to change, and the Group will not now be able to publish its audited annual report and accounts for the year ended 31 March 2019 (the "Accounts") by 30 September 2019 as required by Rule 19 of the AIM Rules for Companies .

The accounting and audit process has been extended this year by the complexities with the accounting for the Medimark acquisition and the restatement of our 2018 results for the effects of IFRS15. We are now in the process of finalising the audit process for the year and the Accounts will be published as soon as possible.

Dealings in the Company's ordinary shares will therefore be temporarily suspended from 7.30 a.m. tomorrow, 1 October 2019, until such time as the Accounts have been duly published in compliance with AIM Rule 19.

As set out in the preliminary results issued earlier, the Company continues to make good progress, had cash balances of £2.8m at the year end and the Directors remain confident in the outlook.
