Retail Offer to raise up to £1 million

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, announces a retail offer via the BookBuild Platform to raise up to £1 million (the "Retail Offer") through the issue of new ordinary shares of 0.1 pence each in the capital of the Company ("Ordinary Shares").

Under the Retail Offer up to 1,098,901 new Ordinary Shares (the "Retail Offer Shares") will be made available at an issue price of 91 pence per new Ordinary Share (the "Issue Price") to new retail investors and existing shareholders of the Company in the United Kingdom through financial intermediaries registered with the Bookbuild Platform.

In addition to the Retail Offer and as announced earlier today, the Company has conditionally raised gross proceeds of approximately £14 million through a placing and subscription of new Ordinary Shares (respectively, the "Placing Shares" and the "Subscription Shares", and together with the Retail Offer Shares, the "New Ordinary Shares") at the Issue Price (respectively, the "Placing" and the "Subscription", and together with the Retail Offer, the "Fundraise"). The first tranche of the Placing of approximately £10.73 million is expected to complete on or around 10 July 2026, and the second tranche of the Placing and Subscription of approximately £3.27 million is expected to complete on or around 29 July 2026, subject to the passing of resolutions at a General Meeting as detailed below.

Net proceeds from the Retail Offer will be used for the same purposes as funds raised from the Placing and Subscription as set out in the Company's announcement of 6 July 2026.

The issue of the Retail Offer Shares is conditional upon, inter alia, the passing of resolutions to be proposed at a General Meeting, which is expected 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. Conditional upon the passing of the resolutions at the General Meeting, the Retail Offer Shares to be issued pursuant to the Retail Offer are expected to be admitted to trading on the AIM market operated by the London Stock Exchange ("Retail Admission") 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)).

Completion of the Retail Offer is conditional, inter alia, upon the completion of the Placing and the Subscription. However, completion of the Placing and the Subscription is not conditional on the completion of, or part of, the Retail Offer.

Key investment risks

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's Ordinary Shares or amounts to investment, taxation or legal advice.

An investment in the Company will place capital at risk. The value of investments, and any income, can go down as well as up, so investors could get back less than the amount invested. The return of your investment is not guaranteed, and you may get back less than you originally invested. Neither past performance nor any forecasts should be considered a reliable indicator of future results.

Unless otherwise defined, definitions contained in this Announcement have the same meaning as set out in the announcement made by the Company on 6 July 2026.
