Result of Retail Offer & Notice of GM

£10 million conditionally raised pursuant to the Placing, Subscription and the Retail Offer

On 13 March 2026 EnSilica plc (AIM: ENSI), a leading fabless, application-specific chipmaker, announced that it had conditionally raised gross proceeds of approximately £9.7 million at the Issue Price of 47 pence per share through (i) the Placing of 20,632,297 Placing Shares to new and existing institutional investors and (ii) the Subscription for 6,000 Subscription Shares. Shortly thereafter EnSilica also announced the launch of the Retail Offer to existing shareholders of the Company.

The Retail Offer closed at 4.00 p.m. yesterday, 17 March 2026, and the Directors are pleased to announce that it was significantly oversubscribed with total demand received over £0.9 million. Consequently, demand has been scaled back to within the previously set maximum of £0.3 million.

Allocations were made to existing Shareholders, applying the principles of soft pre-emption1. Given the significant demand, existing Shareholders received 100 per cent. of their soft pre-emptive allowance, when their order matched or exceeded their soft pre-emptive allowance. Where the order was greater than the soft pre-emptive allowance shareholders received c. 1.24% of their additional demand1.

Accordingly, subject to the passing of certain Resolutions at the forthcoming General Meeting (as detailed below), the Retail Offer will result in the issue of a total of 638,297 Retail Offer Shares at the Issue Price, to raise gross proceeds of approximately £0.3 million. As a result, the Company has conditionally raised a total of approximately £10 million pursuant to the Placing, Subscription and the Retail Offer (together, the "Fundraising").

Notice of General Meeting and posting of Circular

The first tranche of the Fundraising, with gross proceeds of approximately £4.54 million, completed on 17 March 2026. Completion of the Retail Offer, the Subscription and the Second Tranche Placing are subject to, inter alia, the passing of certain Resolutions at a General Meeting of the Company on 7 April 2026 to enable the allotment of new Ordinary Shares pursuant to the Second Tranche Placing, the Subscription and the Retail Offer.

The Company will today post a Circular to Shareholders containing details of the Fundraising and the notice of General Meeting to be held on 7 April 2026. A copy of the Circular will be available on the Company's website later today at www.ensilica.com.

Admission to AIM

Application has been made to the London Stock Exchange plc for the 11,616,531 new Ordinary Shares to be issued pursuant to the Second Tranche Placing, the Subscription and the Retail Offer to be admitted to trading on AIM and, subject to the passing of the Resolutions, it is expected that such Admission will become effective and dealings in such new Ordinary Shares will commence on AIM at 8.00 a.m. on 8 April 2026.

1Soft pre-emptive allowance calculation: Existing shares X 22.025% (Dilution from total new shares being issued) = Soft pre-emptive allowance allocation shares.

Additional Demand: (Total Order shares - Soft Pre-emptive allowance allocation shares) x c.1.24% = Additional demand allocation shares.

Unless otherwise defined, definitions contained in this Announcement have the same meaning as set out in the announcement made by the Company on 12 March 2026.
