Retail Offer to raise up to £1.2 million

Quadrise Plc (AIM:QED), the manufacturer of lower cost, lower emission, replacement fuels and biofuels for shipping and heavy industry, is pleased to announce a retail offer via the BookBuild Platform to raise gross proceeds of up to £1.2 million (the "Retail Offer") through the issue of new ordinary shares of £0.01 each in the capital of the Company ("Ordinary Shares").

Under the Retail Offer up to 120,000,000 new Ordinary Shares (the "Retail Offer Shares") will be made available at a price of 1.0 pence per Retail Offer Share (the "Issue Price").

In addition to the Retail Offer, and as announced by the Company earlier today, the Company has conditionally raised gross proceeds of £1.2 million by way of a placing (the "Placing") of 119,000,000 new Ordinary Shares (the "Placing Shares") and direct subscriptions (the "Subscription") for 1,000,000 new Ordinary Shares (the "Subscription Shares"), in each case at the Issue Price.

A separate announcement was released by the Company on 7 July 2026 which sets out the terms and conditions of the Placing and the Subscription together with the reasons for the Placing and the Subscription and the use of proceeds. Should the Retail Offer be fully subscribed, the net proceeds will provide additional resources to enable the Company to:

• Progress projects and trials to commercial revenue generation, with an expected positive cash contribution of approx. £3.6m to 30 June 2028.
• Support working capital requirements through to positive cashflows in FY 2028-29.
• Progress our carefully assessed near-term priority business development pipeline, R&D activity and digitalisation initiatives.

The Placing Shares, the Subscription Shares and the Retail Offer Shares (together, the "Fundraise Shares") will be issued and allotted under the Company's existing allotment and disapplication of pre-emption rights authorities obtained at the Company's last annual general meeting held on 28 November 2025.

The Retail Offer is not part of the Placing or the Subscription. Completion of the Retail Offer is conditional upon, inter alia, completion of the Placing and the Subscription and the Fundraise Shares being admitted to trading on the AIM market ("AIM") ("Admission") operated by London Stock Exchange plc (the "London Stock Exchange"). Completion of the Placing and the Subscription is not conditional on the completion of the Retail Offer.

Application will be made to the London Stock Exchange for the Retail Offer Shares to be admitted to trading on AIM ("Second Admission"). It is anticipated that Second Admission will become effective and that dealings in the Retail Offer Shares will commence on AIM at 8.00 a.m. on 16 July 2026 or such later time and/or date as Shore, VSA, Cavendish (in each case, as defined below) and the Company agree (being in any event no later than 8.00 a.m. on 10 August 2026).

UK Product Governance Requirements

Solely for the purposes of the product governance requirements of Chapter 3 of the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK MiFIR Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK MiFIR Product Governance Requirements) may otherwise have with respect thereto, the Retail Offer Shares have been subject to a product approval process, which has determined that the Retail Offer Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in paragraphs 3.5 and 3.6 of the FCA's Conduct of Business Sourcebook ("COBS"); and (ii) eligible for distribution through all permitted distribution channels (the "Target Market Assessment"). Notwithstanding the Target Market Assessment, distributors should note that: the price of the Retail Offer Shares may decline and investors could lose all or part of their investment; the Retail Offer Shares offer no guaranteed income and no capital protection; and an investment in the Retail Offer Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The Target Market Assessment is without prejudice to any contractual, legal or regulatory selling restrictions in relation to the Retail Offer.
