EnSilica plc

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

Retail Offer to raise up to £0.5 million

EnSilica (AIM:ENSI), a leading mixed signal chip maker, is pleased to announce a retail offer to existing shareholders of the Company in the United Kingdom via the BookBuild platform (the "Retail Offer") of new ordinary shares of 0.1p each ("Ordinary Shares") in the capital of the Company (the "Retail Offer Shares") to raise up to £0.5 million (before expenses) at an issue price of 70 pence per new Ordinary Share (the "Issue Price").

In addition to the Retail Offer, the Company also announced earlier today that it has conditionally raised £2.0 million before expenses through a placing and subscription of 2,857,143 new Ordinary Shares (the "Placing and Subscription Shares" and together with the Retail Offer Shares, the "Fundraise Shares") at the Issue Price (the "Placing and Subscription" and together with the Retail Offer, the "Fundraise").

A separate announcement has been made today with details of the Placing and Subscription and their respective terms and conditions and setting out the background to the Fundraise and use of proceeds. The net proceeds of the Retail Offer will be utilised in the same way as the proceeds of the Placing and Subscription.

The Retail Offer is not part of the Placing and Subscription. Completion of the Placing and Subscription is not conditional on the completion of the Retail Offer. However, completion of the Retail Offer is conditional upon, inter alia, (i) completion of the Placing and Subscription in accordance with their respective terms and (ii) the Placing and Subscription Shares being admitted to trading on AIM ("Admission"). It is currently anticipated that Admission will become effective and that dealings in the Placing Shares and the Subscription Shares will commence on AIM at 8.00 a.m. on or around 14 March 2023.

Application will be made to London Stock Exchange plc for the Retail Offer Shares to be admitted to trading on AIM ("Retail Admission"). It is currently anticipated that Retail Admission will become effective and that dealings in the Retail Offer Shares will commence on AIM at 8.00 a.m. on or around 15 March 2023.

The Placing Shares, the Subscription Shares and the Retail Offer Shares will rank pari passu with the existing Ordinary Shares in issue.

Expected Timetable in relation to the Retail Offer

Any changes to the expected timetable set out above will be notified by the Company through a Regulatory Information Service. References to times are to London times unless otherwise stated.

Dealing Codes

Retail Offer

The Company values its existing retail shareholder base, which has supported the Company alongside institutional investors since its Ordinary Shares were admitted to trading on AIM on 24 May 2022. Given the support of its existing retail shareholders, the Company believes that it is appropriate to provide its existing retail shareholders in the United Kingdom the opportunity to participate in the Retail Offer.

The Company is therefore making the Retail Offer available in the United Kingdom only through the financial intermediaries which will be listed, subject to certain access restrictions, on the following website: https://www.bookbuild.live/deals/KNQNKQ/authorised-intermediaries.

Allenby Capital Limited ("Allenby Capital") will be acting as coordinator in relation to the Retail Offer (the "Retail Offer Coordinator").

Existing retail shareholders can contact their broker or wealth manager to participate in the Retail Offer. In order to participate in the Retail Offer, each intermediary must be on-boarded onto the BookBuild platform and agree to the final terms and the retail offer terms and conditions, which regulate, inter alia, the conduct of the Retail Offer on market standard terms and provide for the payment of commission to any intermediary that elects to receive a commission and/or fee (to the extent permitted by the FCA Handbook Rules) from the Retail Offer Coordinator (on behalf of the Company).

Participation of any intermediary is in the Retail Offer is at the absolute discretion of the Retail Offer Coordinator.

Any expenses incurred by any intermediary are for its own account. Eligible Shareholders should confirm separately with any intermediary whether there are any commissions, fees or expenses that will be applied by such intermediary in connection with any application made through that intermediary pursuant to the Retail Offer.

The Retail Offer will be open to Eligible Shareholders in the United Kingdom at 8.00 a.m. on 10 March 2023. The Retail Offer is expected to close at 5:00 p.m. on 13 March 2023 but may, at the absolute discretion of the Retail Offer Coordinator, be closed early or cancelled. Eligible Shareholders should note that financial intermediaries may have earlier closing times. The Retail Offer may close early if it is oversubscribed or otherwise at the absolute discretion of the Retail Offer Coordinator or BookBuild.

If any intermediary has any questions about how to participate in the Retail Offer on behalf of Eligible Shareholders, please contact BookBuild at [email protected].

The Retail Offer the subject of this announcement is and will, at all times, only be made to, directed at and may only be acted upon by those persons who are, shareholders in the Company.  To be eligible to participate in the Retail Offer, applicants must meet the following criteria before they can submit an order for Retail Offer Shares: (i) be a customer of one of the participating intermediaries listed on the above website; (ii) be resident in the United Kingdom; and (iii) be a shareholder in the Company (which may include individuals aged 18 years or over, companies and other bodies corporate, partnerships, trusts, associations and other unincorporated organisations and includes persons who hold their shares in the Company directly or indirectly through a participating intermediary). For the avoidance of doubt, persons who only hold CFDs, spreadbets and/or similar derivative instruments in relation to shares in the Company are not eligible to participate in the Retail Offer.

The Company and the Retail Offer Coordinator reserve the right to scale back any order at their absolute discretion. The Company and the Retail Offer Coordinator reserve the right at their absolute discretion to reject any application for subscription under the Retail Offer without giving any reason for such rejection.

It is vital to note that once an application for Retail Offer Shares has been made and accepted via an intermediary, it cannot be withdrawn.

The Retail Offer Shares will, when issued, be credited as fully paid and will rank pari passu in all respects with existing Ordinary Shares including the right to receive all dividends and other distributions declared, made or paid after their date of issue.

The Retail Offer is an offer to subscribe for transferable securities, the terms of which ensure that the Company is exempt from the requirement to issue a prospectus under Regulation (EU) 2017/1129 as it forms part of UK law by virtue of the European Union (Withdrawal) Act 2018. It is a term of the Retail Offer that the aggregate total consideration payable for the Retail Offer Shares will not exceed £500,000. Accordingly, the exemption from the requirement to publish a prospectus, set out in section 86(1)(e) of the Financial Services and Markets Act 2000 (as amended), will apply to the Retail Offer.

The Retail Offer is not being made into any jurisdiction other than the United Kingdom, and is not being made to US Persons (as defined in Regulation S of the US Securities Act 1933, as amended).

No offering document, prospectus or admission document has been or will be prepared or submitted to be approved by the Financial Conduct Authority, (or any other authority) in relation to the Retail Offer, and investors' commitments will be made solely on the basis of the information contained in this announcement and information that has been published by or on behalf of the Company prior to the date of this announcement by notification to a Regulatory Information Service in accordance with the Financial Conduct Authority's Disclosure Guidance and Transparency Rules and the Market Abuse Regulation (EU Regulation No. 596/2014) ("MAR") as it forms part of United Kingdom law by virtue of the European Union (Withdrawal) Act 2018 (as amended).

There is a minimum subscription of £100 per investor under the terms of the Retail Offer which is open to Eligible Shareholders in the United Kingdom subscribing via the intermediaries which will be listed, subject to certain access restrictions, on the following website: https://www.bookbuild.live/deals/KNQNKQ/authorised-intermediaries. There is no maximum application amount to apply in the Retail Offer except that the aggregate total consideration for the Retail Offer shall not exceed £500,000. The terms and conditions on which investors subscribe will be provided by the relevant financial intermediaries including relevant commission or fee charges.

Investors should make their own investigations into the merits of an investment in the Company. Nothing in this announcement amounts to a recommendation to invest in the Company or amounts to investment, taxation or legal advice. 

It should be noted that a subscription for Retail Offer Shares and investment in the Company carries a number of risks. Investors should take independent advice from a person experienced in advising on investment in securities such as the Retail Offer Shares if they are in any doubt.

UK Product Governance Requirements

Solely for the purposes of the product governance requirements of Chapter 3 of the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK MiFIR Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK MiFIR Product Governance Requirements) may otherwise have with respect thereto, the Retail Offer Shares have been subject to a product approval process, which has determined that the Retail Offer Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in paragraphs 3.5 and 3.6 of COBS; and (ii) eligible for distribution through all permitted distribution channels (the "UK Target Market Assessment").

Notwithstanding the UK Target Market Assessment, distributors should note that: the price of the Retail Offer Shares may decline and investors could lose all or part of their investment; the Retail Offer Shares offer no guaranteed income and no capital protection; and an investment in the Retail Offer 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 UK Target Market Assessment is without prejudice to any contractual, legal or regulatory selling restrictions in relation to the Retail Offer.

EU Product Governance Requirements

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 Retail Offer Shares have been subject to a product approval process, which has determined that the Retail Offer Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the "EU Target Market Assessment").

Notwithstanding the EU Target Market Assessment, distributors should note that: the price of the Retail Offer Shares may decline and investors could lose all or part of their investment; the Retail Offer Shares offer no guaranteed income and no capital protection; and an investment in the Retail Offer 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 EU Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Retail Offer.

For the avoidance of doubt, the UK Target Market Assessment and the EU Target Market Assessment do 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 Retail Offer Shares. Each distributor is responsible for undertaking its own target market assessment in respect of the Retail Offer Shares and determining appropriate distribution channels.
