Result of Retail Offer

Further to the announcement by the Company in respect of the Retail Offer dated 3 July 2026 (the "Retail Offer Announcement"), Ilika plc (AIM: IKA), is pleased to announce that the Retail Offer, which was oversubscribed, successfully completed and closed at 4:30 p.m. on 7 July 2026, and that it has conditionally raised approximately £0.5 million in the Retail Offer through the issue of 1,785,714 Retail Offer Shares at the Issue Price of 28 pence per share.

Consequently, it is anticipated that 16,199,996 Placing Shares, 71,429 Director Subscription Shares and 1,785,714 Retail Offer Shares (together, the "New Ordinary Shares") will be issued in relation to the Capital Raising, resulting in a total of 18,057,139 New Ordinary Shares being issued. The total gross monies raised (before expenses) is approximately £5.0 million. The net proceeds of the Capital Raising will be used to advance the commercial status of the Company's two product lines, specifically supporting the commercial launch and ramp up of the small format Stereax technology, and the continued development and delivery of the large format Goliath technology, through to a position where it will be possible to secure commercial licensing agreements with commercial partners.

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.70.1 per cent of their additional demand2.

Total Voting Rights and Admission

Application has been made to the London Stock Exchange for the New Ordinary Shares to be admitted to trading on AIM. It is expected that dealings in the New Ordinary Shares will commence on or around 8.00 a.m. on 9 July 2026 (or such time and/or date as the Company and Cavendish may agree, being not later than 8.00 a.m. on 23 July 2026 the Long Stop Date).

Following Admission of the New Ordinary Shares, the Company will have 198,889,314 Ordinary Shares in issue with the Company holding no Ordinary Shares in treasury. Therefore, the total number of voting rights will also be 198,889,314. This figure may be used by shareholders 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 share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.

Other than where defined, capitalised terms used in this announcement have the meanings given to them in the Retail Offer Announcement.
