Quadrise plc

("Quadrise", "QED" or the "Company")

Publication of 2025 Sustainability Report

Quadrise plc (AIM: QED), the technology company focused on the decarbonisation of shipping and heavy industry through deployment of low emission fuels and biofuels, is pleased to announce the publication of its fourth annual Sustainability Report, which is now available on the Company's website: Sustainability Report 2025

Highlights:

·   Formal adoption of the 2023 QCA Corporate Governance Code, reinforcing transparent decision‑making and proportionate oversight appropriate to Quadrise's growth stage.

·    Strengthened Company's own operational performance by lowering emissions intensity per Full Time Equivalent ("FTE") by 21%.

·    Focus in 2026 on commencing commercial trials with MSC and progressing core projects in the USA, Panama and Morocco.

Selected outcomes aligned to disclosure themes:

·   Sparkle Power trial: Proof‑of‑concept and validation testing of MSAR® and bioMSAR™ on Everllence four‑stroke engines demonstrated stable operation up to 74% engine load using existing equipment.

·    Sustainable Ships tool: Launch of a free, online fuel‑comparison calculator to model MSAR® and bioMSAR™ against conventional fuels for real trade parameters, supporting transparent, evidence‑based choices.

·    SEASTARS: Continued participation in the EU‑funded SEASTARS Innovation Action alongside shipowners, technology developers and research organisations.

·    First commercial licensing agreement executed with Valkor (Utah, USA).

·    Completed the first engine trials of bioMSAR™ Zero - a very important step toward a future net zero emulsion fuel.

Outlook:

·    The Company sees no substantive impact from the delayed International Maritime Organisation´s ("IMO") Net-zero Framework decision and expects regional measures to continue shaping compliance.

·    The Company continue to advance the commercialisation of bioMSAR™ and develop bioMSAR™Zero.

·    Positioning MSAR® and bioMSAR™ as complementary to other measures available to lower emissions for existing vessels, solutions that are available today at low cost.

Commenting on the report Andy Morrison Chair of Quadrise, said:

"We are delighted to publish our latest Sustainability Report which updates on the business, our approach to sustainability, our values and how we believe our proposition can help shape the future of energy particularly in the maritime industry.

"MSAR® and bioMSAR™ are practical transition fuels for the shipping industry that provide the opportunity for immediate emissions reductions for existing fleets, without the need for substantial retrofitting.

"The Company´s priority in the year ahead is to further build on our strategy and to accelerate progress on our key projects and to build the evidence required for adoption of MSAR® and bioMSAR™. The Board believes the Company remains well positioned to contribute to the energy transition and to build long-term value for shareholders."
