Result of oversubscribed Placing and Subscription

On 6 July 2026, EnSilica plc (AIM: ENSI), a leading fabless microchip maker with a growing portfolio of reusable IP, serving the Space and Communications, Industrial, and Automotive markets, announced a proposed equity fundraising by way of an accelerated bookbuild (the "Fundraising Announcement").

The Board is pleased to announce that the Bookbuild has concluded and that it has conditionally raised gross proceeds of approximately £14 million at the Issue Price of 91 pence per share through: (i) the Placing of 15,381,315 Placing Shares to new and existing institutional investors; and (ii) the Subscription for 3,300 Subscription Shares.

The net proceeds of the Placing and the Subscription will enable the Company to accelerate new products and projects and its growing contract pipeline, as set out in the Fundraising Announcement.

Due to the limited existing share authorities available to issue new Ordinary Shares, the Placing will be conducted in two tranches, as follows:

• a placing of 11,787,723 Placing Shares (the "First Tranche Placing Shares") at the Issue Price, raising approximately £10.73 million, to be issued pursuant to the Company's existing authorities to issue and allot equity securities on a non-pre-emptive basis (the "First Tranche Placing"). The First Tranche Placing is conditional upon, inter alia, First Admission becoming effective on or around 10 July 2026; and
• a conditional placing of 3,593,592 Placing Shares (the "Second Tranche Placing Shares") at the Issue Price, raising approximately £3.27 million, to be issued conditional, inter alia, on the passing of the Resolutions at the General Meeting (the "Second Tranche Placing"). The General Meeting is expected to take place on 27 July 2026, notice of which will be sent to shareholders later this week.

In addition to the Placing and the Subscription, the Company expects to shortly announce a separate Retail Offer through the BookBuild Platform. This is expected to remain open until 12.00 p.m. on 9 July 2026.

The Second Tranche Placing, the Subscription and the Retail Offer (together the "Conditional Fundraising") are conditional upon, inter alia, the passing of the Resolutions to be proposed at the General Meeting to be held at the offices of Fieldfisher LLP at Riverbank House, 2 Swan Lane, London, EC4R 3TT at 10.00 a.m. on 27 July 2026 and Second Admission becoming effective on or around 29 July 2026.

A Circular, containing details of the Fundraising and the notice of General Meeting is expected to be despatched to Shareholders on or around 10 July 2026. Further details in relation to the expected Fundraising timetable is appended below.

The Placing is also conditional on the Placing Agreement not being terminated in accordance with its terms.

Director participation

Kristoff Rademan, EnSilica's Chief Financial Officer, has conditionally subscribed for a total of 3,300 new Ordinary Shares at the Issue Price in the Subscription. On Second Admission and excluding the Retail Offer, Kristoff Rademan will hold 19,300 Ordinary Shares representing approximately 0.014 per cent. of the enlarged issued share capital.

The FCA notification in respect of this director dealing, made in accordance with the requirements of UK MAR, is appended further below.

Substantial shareholder participation

Esterhuyzen Limited ("Esterhuyzen"), a substantial shareholder of the Company for the purpose of the AIM Rules for Companies ("AIM Rules"), has subscribed for 6,000,000 Placing Shares at the Issue Price. On First Admission, Esterhuyzen will hold 21,500,000 Ordinary Shares representing approximately 16.58 per cent. of the enlarged issued share capital.

The participation by Esterhuyzen in the Placing is deemed to be a related party transaction for the purpose of AIM Rule 13 (the "Transaction"). The independent Directors, which excludes Kristoff Rademan, consider having consulted with the Company's nominated adviser, Allenby Capital Limited, that the terms of the Transaction are fair and reasonable insofar as the Company's shareholders are concerned.

Change to significant shareholding in the Company

As a result of the issue of the First Tranche Placing Shares, the shareholding of Ian Lankshear, CEO of the Company, will be diluted on First Admission to approximately 12.37 per cent. (the number of Ordinary Shares he holds will remain the same at 16,040,358).

Admission to AIM

Application has been made to the London Stock Exchange plc for the admission of the First Tranche Placing Shares to trading on AIM and it is expected that First Admission will occur at 8.00 a.m. on or around 10 July 2026.

Application will be made to the London Stock Exchange plc for the admission of the Second Tranche Placing Shares, the Subscription Shares and the Retail Offer Shares (the "Conditional Fundraising Shares") to trading on AIM and, subject to, inter alia, approval of the Resolutions by Shareholders at the General Meeting, it is expected that Second Admission will become effective and dealings in the Conditional Fundraising Shares will commence at 8.00 a.m. on or around 29 July 2026 (or such later time and/or date as the Bookrunners and the Company may agree (being in any event no later than 8.00 a.m. on 12 August 2026)).

Total voting rights

Immediately following First Admission, the Company will have 129,664,953 Ordinary Shares in issue, each with one voting right. There are no shares held in treasury. Therefore, the Company's total number of Ordinary Shares in issue and voting rights will be 129,664,953 and this figure may be used by shareholders from First Admission 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 Company under the FCA's Disclosure Guidance and Transparency Rules.

Subject to, inter alia, the passing of the Resolutions, a further announcement will be made in due course in relation to the total number of voting rights of the Company from Second Admission.

Unless otherwise defined, definitions contained in this Announcement have the same meaning as set out in the Fundraising Announcement.
