SDI Group plc

("SDI", the "Company" or the "Group")

Exercise of Options and Total Voting Rights and

Proposed Secondary Placing of 1,260,000 Ordinary Shares in the Company

SDI Group plc, the AIM quoted group focused on the design and manufacture of scientific and technology products for use in digital imaging and sensing and control applications, announces that it has been informed by the Directors of the Company of their intention to sell, in aggregate, 1,260,000 ordinary shares of 1 pence each ("Ordinary Shares") in the capital of Company (the "Placing Shares") at a price of 195 pence per Placing Share (the "Placing").

Each of Ken Ford (Chairman), Mike Creedon (CEO), Jon Abell (CFO), David Tilston (Non-Executive Director) and Isabel Napper (Non-Executive Director) (together, the "Selling Shareholders") intend to participate in the Placing.

Exercise of Options

The Company also announces that it has issued and allotted a total of 1,889,129 new Ordinary Shares following the exercise of options by all of the directors (as named above). A number of these new Ordinary Shares will be sold in the Placing by certain directors of the Company to satisfy tax obligations.

Further information with regards to the exercise of options and Placing Shares can be found in the table below.

Admission and Total Voting Rights

Application has been made to the London Stock Exchange for the 1,889,129 new Ordinary Shares to be admitted to trading on AIM ("Admission") and it is expected that Admission will become effective and trading will commence at 8.00 a.m. on 20 January 2022.

After Admission, the total number of Ordinary Shares in issue will be 102,047,293 and the total number of voting rights will therefore be 102,047,293. This figure may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.

Placing Further Information

finnCap Ltd ("finnCap") is acting as sole bookrunner ("Bookrunner") in relation to the Placing.

The sale of the Placing Shares will be effected by way of an accelerated bookbuild to institutional investors which will be launched immediately following this announcement (the "Bookbuild"). A further announcement will be made following completion of the Bookbuild.

The timing for the close of the Bookbuild and the distribution of allocations will be at the absolute discretion of finnCap. The Selling Shareholders have entered into a secondary placing agreement with finnCap to act as Bookrunner.

The Placing Shares represent in aggregate 1.23 per cent. of the enlarged issued share capital of the Company following Admission. Details of the numbers of Placing Shares to be disposed of by the Selling Shareholders are as follows:

Information to Distributors

Solely for the purposes of the product governance requirements contained within: (a) EU Directive 2014/65/EU on markets in financial instruments, as amended ("MiFID II"); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the "MiFID II Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the Placing Shares have been subject to a product approval process, which has determined that the Placing Shares are: (i) compatible with an end target market of (a) retail investors, (b) investors who meet the criteria of professional clients and (c) eligible counterparties, each as defined in MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the "Target Market Assessment"). Notwithstanding the Target Market Assessment, distributors should note that: the price of the Placing Shares may decline and investors could lose all or part of their investment; the Placing Shares offer no guaranteed income and no capital protection; and an investment in the Placing Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Placing.  Furthermore, it is noted that, notwithstanding the Target Market Assessment, finnCap will only procure investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Placing Shares.

Each distributor is responsible for undertaking its own target market assessment in respect of the Placing Shares and determining appropriate distribution channels.
