Launch of Retail Offer

MicroSalt is pleased to announce the launch of an exempt public offer of up to 666,666 new ordinary shares of £0.001625 each in the capital of the Company (the "Retail Offer Shares") to retail investors in the UK via BookBuild (the "Retail Offer"), at an issue price of 45 pence per Retail Offer Share (the "Issue Price").

In addition to the Retail Offer, the Company has also completed a fundraise by way of a subscription of 3,333,334 new ordinary shares of £0.001625 each in the capital of the Company (the "Subscription Shares" and together with the Retail Offer Shares, the "New Ordinary Shares") at the Issue Price (the "Subscription" and together with the Retail Offer, the "Fundraise"). A separate announcement has been made regarding the Subscription. For the avoidance of doubt, the Retail Offer is not part of the Subscription.

The Issue Price represents a discount of approximately 13.5 per cent. to the closing share price of 52.0 pence on 8 December 2025.

The Retail Offer is conditional on the Retail Offer Shares being admitted to trading on the AIM market operated by the London Stock Exchange plc ("Admission"). Admission of the Retail Offer Shares is expected to take place at 8:00 a.m. on 15 December 2025.

The net proceeds of the Fundraise will further strengthen the Company's balance sheet and provide additional funds for staffing, marketing and working capital.

Expected Timetable in relation to the Retail Offer
