Quadrise Plc

(the "Company" and together with its subsidiaries the "Group" or "Quadrise")

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).

Retail Offer

The Company values its retail shareholder base and believes that it is appropriate to provide its existing retail shareholders in the United Kingdom the opportunity to participate in the Retail Offer.

The Company is therefore making the Retail Offer available in the United Kingdom through the financial intermediaries which will be listed, subject to certain access restrictions, on the following website: https://www.bookbuild.live/deals/6QG6K7/authorised-intermediaries  
Shore Capital Stockbrokers Limited ("Shore") will be acting as retail offer coordinator in relation to this Retail Offer (the "Retail Offer Coordinator").

Existing retail shareholders can contact their broker or wealth manager ("Intermediary") to participate in the Retail Offer. In order to participate in the Retail Offer, each Intermediary must be on-boarded onto the BookBuild platform and agree to the final terms and the retail offer terms and conditions, which regulate, inter alia, the conduct of the Retail Offer on market standard terms and provide for the payment of commission to any Intermediary that elects to receive a commission and/or fee (to the extent permitted by the FCA Handbook Rules) from the Retail Offer Coordinator (on behalf of the Company).

Any expenses incurred by any Intermediary are for its own account. Investors should confirm separately with any Intermediary whether there are any commissions, fees or expenses that will be applied by such Intermediary in connection with any application made through that Intermediary pursuant to the Retail Offer.

The Retail Offer will be open to eligible investors in the United Kingdom at 8.00 a.m. on 8 July 2026. The Retail Offer is expected to close at 2.00 p.m. on 13 July 2026. Investors should note that Intermediaries may have earlier closing times. The Retail Offer may close early if it is oversubscribed.

If any Intermediary has any questions about how to participate in the Retail Offer on behalf of existing retail shareholders in the Company, please contact BookBuild at email: support@bookbuild.live.

The Retail Offer the subject of this announcement is and will, at all times, only be made to, directed at and may only be acted upon by those persons who are, shareholders in the Company. To be eligible to participate in the Retail Offer, applicants must meet the following criteria before they can submit an order for Retail Offer Shares: (i) be a customer of one of the participating intermediaries listed on the above website; (ii) be resident in the United Kingdom and (iii) be a shareholder in the Company (which may include individuals aged 18 years or over, companies and other bodies corporate, partnerships, trusts, associations and other unincorporated organisations and includes persons who hold their shares in the Company directly or indirectly through a participating intermediary). For the avoidance of doubt, persons who only hold CFDs, Spreadbets and/or similar derivative instruments in relation to shares in the Company are not eligible to participate in the Retail Offer.

The Company reserves the right to scale back any order at its discretion. The Company reserves the right to reject any application for subscription under the Retail Offer without giving any reason for such rejection.

It is vital to note that once an application for Retail Offer Shares has been made and accepted via an intermediary, it cannot be withdrawn.

The Retail Offer Shares will, when issued, be credited as fully paid and will rank pari passu in all respects with existing Ordinary Shares including the right to receive all dividends and other distributions declared, made or paid after their date of issue.

The Retail Offer is offered in the United Kingdom under an exemption from the prohibition on public offers specified in Part 1 of Schedule 1 of the Public Offers and Admissions to Trading Regulations 2024 (the "POATR"). In addition, there is no requirement for publication of a prospectus pursuant to the POATR and the FCA Prospectus Rules: Admission to Trading on a Regulated Market Sourcebook (the "PRM"), or for approval of the same by the Financial Conduct Authority (the "FCA"). The Retail Offer is not being made into any jurisdiction other than the United Kingdom or to US Persons (as defined in Regulation S of the Securities Act).

No offering document, prospectus or admission document has been or will be prepared or submitted to be approved by the FCA (or any other authority) in relation to the Retail Offer, and investors' commitments will be made solely on the basis of the information contained in this announcement and information that has been published by or on behalf of the Company prior to the date of this announcement by notification to a Regulatory Information Service in accordance with the FCA's Disclosure Guidance and Transparency Rules and the Market Abuse Regulation (EU Regulation No. 596/2014) ("MAR") as it forms part of United Kingdom law by virtue of the European Union (Withdrawal) Act 2018 (as amended).

There is a minimum subscription of £100 per investor under the terms of the Retail Offer which is open to investors in the United Kingdom subscribing via the Intermediaries which will be listed, subject to certain access restrictions, on the following website: https://www.bookbuild.live/deals/6QG6K7/authorised-intermediaries  
There is no maximum application amount to apply in the Retail Offer. The terms and conditions on which investors subscribe will be provided by the relevant financial Intermediaries including relevant commission or fee charges.

Investors should make their own investigations into the merits of an investment in the Company. Nothing in this announcement amounts to a recommendation to invest in the Company or amounts to investment, taxation or legal advice.

It should be noted that a subscription for Retail Offer Shares and investment in the Company carries a number of risks. Investors should take independent advice from a person experienced in advising on investment in securities such as the Retail Offer Shares if they are in any doubt.

An investment in the Company will place capital at risk. The value of investments, and any income, can go down as well as up, so investors could get back less than the amount invested. Neither past performance nor any forecasts should be considered a reliable indicator of future results.

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.

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of Chapters 9A or 10A respectively of COBS; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Retail Offer Shares. Each distributor is responsible for undertaking its own target market assessment in respect of the Retail Offer Shares and determining appropriate distribution channels.

EU Product Governance Requirements

Solely for the purposes of the product governance requirements contained within: (a) EU Directive 2014/65/EU on markets in financial instruments, as amended ("MiFID II"); (b) Articles 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the "MiFID II Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the MiFID II 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 MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the "EU Target Market Assessment"). Notwithstanding the EU 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 EU Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Retail Offer.

For the avoidance of doubt, the EU Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase or take any other action whatsoever with respect to the Retail Offer Shares. Each distributor is responsible for undertaking its own target market assessment in respect of the Retail Offer Shares and determining appropriate distribution channels.
