Defined terms used in this announcement have the same meaning as  in the Circular sent to shareholders on 19 January 2021 and available on the Company's website, www.microsaic.com.

Microsaic, the high technology company which develops point-of-need mass spectrometers, designed to improve the efficiency of chemical and biological workflows, is pleased to announce that further to the announcement of the Placing on 19 January 2021 the Broker Option has now closed. The Broker Option was substantially oversubscribed and has been exercised in respect of the maximum 500,000,000 New Ordinary Shares available under the option. This will raise a further £500,000 in gross proceeds for the Company, bringing the total funding conditionally raised from the Placing and the Broker Option (before ex;4penses) to £5.5 million.

Turner Pope, the Company's Placing Agent, has determined all Broker Option Share allocations at its discretion (after consultation with the Company) and has notified counterparties of the number of Broker Option Shares they have been allocated.

Application will be made in due course to the London Stock Exchange for 5,620,000,000 Ordinary Shares, including the Placing Shares, the Fees Shares and the Broker Option Shares, to be admitted to trading on AIM. It is expected that Admission will occur and dealings will commence on 5 February 2021 at 8.00 a.m.. The Transaction is conditional upon, amongst other things, Admission becoming effective and is subject to approval at the General Meeting on 4 February 2021.

Following Admission, the Company will have 6,076,365,146 Ordinary Shares in issue. Therefore, the Company hereby confirms that the total number of voting rights in the Company will, following Admission, be 6,076,365,146. This figure will be confirmed following the result of the General Meeting on 4 February 2021.

Unicorn Asset Management, a substantial shareholder in the Company (and therefore a related party of the Company for the purposes of the AIM Rules), has subscribed for 600,000,000 Placing Shares and 75,000,000 Broker Option Shares at the Placing Price.
