Retail Offer to raise up to £0.3 million

EnSilica plc (AIM: ENSI), a leading fabless, application-specific chipmaker, announces a retail offer via the BookBuild Platform to raise up to £0.3 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 638,297 new Ordinary Shares (the "Retail Offer Shares") will be made available at an issue price of 47 pence per new Ordinary Share (the "Issue Price") to existing shareholders of the Company in the United Kingdom through financial intermediaries registered with Bookbuild.

In addition to the Retail Offer and as announced earlier today, the Company has conditionally raised gross proceeds of approximately £9.7 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 £4.54 million is expected to complete on or around 17 March 2026, and the second tranche of approximately £5.16 million is expected to complete on or around 8 April 2026 subject to the 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 announcement of 12 March 2026.

For the avoidance of doubt, the Retail Offer is not part of the Placing or the Subscription.

The issue of the Retail Offer Shares is conditional upon, inter alia, the passing of the Resolutions to be proposed at the 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 7 April 2026. Conditional upon the passing of the Resolutions, admission of the Retail Offer Shares to be issued pursuant to the Retail Offer being admitted to trading on the AIM market operated by the London Stock Exchange ("Retail Admission") is expected to occur at 8.00 a.m. on or around 8 April 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 22 April 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 the Retail Offer.
