Nouryon update

Quadrise Plc (AIM:QED), the manufacturer of lower cost, lower emission, replacement fuels and biofuels for shipping and heavy industry, provides an update to the announcement on 12 January 2026 of the extension of the Exclusive Global Collaboration and Emulsifiers Sales Agreement ("Agreement") between Quadrise International Limited ("QIL"), a subsidiary of the Company, and Nouryon Surface Chemistry AB ("NSC").

Following the expiry of the Agreement on 31 October 2026, the parties have agreed not to extend the Agreement or enter into a new one until such time as Quadrise projects and volume requirements are confirmed. NSC have however confirmed their interest in pursuing an agreement once the requirements are known and will also continue to support Quadrise’s trials with individual orders.

The Company has already undertaken significant development work on future additive supplies (including emulsifiers) to complement its extensive knowhow and IP position in oil-in-water emulsion fuels. This includes formulation testing using bespoke procedures at the Quadrise Research Facility to broaden the additive supply base for a global range of fuels and biofuel feedstocks. This work is directed to accord flexibility and reinforce the competitiveness of the Company's MSAR® and bioMSAR™ products respectively.
