The 2025 1p & 2p Warrantholders General Meeting of Sundae Bar PLC to be held at the offices of the Company's Solicitors, Druces LLP, 6th Floor, 99 Gresham Street, London, EC2V 7NG at 11:15 a.m. on 15 June 2026.

Further information on the Warrantholders GMs and background to the proposed modifications to the existing 1p and 2p Warrants

There are currently in issue 60,250,000 2023 1p Warrants, 35,000,000 2025 1p Warrants and 2,897,620 2025 2p Warrants (together "Warrants") to subscribe for ordinary shares at either 1p or 2p respectively.

The business to be conducted at the 2023 1p WGM consists of consideration of the following resolutions:-

Resolution 1: Varying the exercise price from 1p to 1.5p per 2023 1p Warrant.

Resolution 2: Varying the exercise period to commencing on 15 June 2026 and ending on 15 June 2028.

Resolution 3: Varying the clauses to reflect a lock-in on exercising or disposing of 2023 1p Warrants from 15 June 2026 for a 12 month period.

Resolution 4: Varying the drafting given the deletion of the original clause 6.2 which will no longer be included.

The business to be conducted at the 2025 1p & 2p WGM consists of consideration of the following resolutions:-

Resolution 1: Varying the exercise price from 1p to 1.5p per 2025 1p Warrant, and from 2p to 2.5p per 2025 2p Warrant.

Resolution 2: Varying the subscription period to commencing on 15 June 2026 and ending on the Expiry Date.

Resolution 3: Varying the Expiry Date to 15 June 2028.

Resolution 4: Including a clause to provide for a lock-in on exercising or disposing of 2025 1p & 2p Warrants from 15 June 2026 for a 12 month period.

The Board believes that Sundae Bar is at an important stage in its development, and that the next two years represent a significant opportunity for the Company to grow and create long-term value for all stakeholders. The Board would like to offer Warrantholders the opportunity to be able to participate fully in that potential, and the proposed extension is designed to give you the time to do so.

The Warrants were issued a few years ago at a materially lower exercise price relative to the Company's present market valuation and are approaching expiry. In their current form, the Warrants create a significant risk of concentrated short-term conversion and disposal activity which may create unnecessary volatility in the Company's share price, adversely affect market confidence, and potentially undermine shareholder value.

The Board is confident in the Company's prospects and believes that the extended exercise window gives Warrantholders a meaningful opportunity to realise value from their investment at the right time. The Board believes the proposed amendments to the Warrants are in the best interests of the Company and all shareholders.

In summary, it is the belief of the Board that the variation proposals contained in the circular and detailed in 2023 and 2025 Resolutions are appropriate for the needs of the Company and are in the interests of 2023 Warrantholders as well as 2025 1p & 2p Warrantholders.
