Invinity Energy Systems plc announced that it has entered into an agreement with its Taiwanese strategic partner, Everdura, to undertake domestic manufacturing of its next-generation vanadium flow battery ("VFB") product, code-named "Mistral", to serve the Taiwanese and other markets ("the Agreement"). Everdura has been Invinity's reseller since 1 December 2022. Everdura's parent company, Everbrite, made a PS2.5m strategic investment into the Company which was announced 22 February 2023.

On 14 September 2023, Everdura placed a 14.4 MWh pre-order for Mistral and entered into a MoU which proposed a strategic manufacturing partnership with Invinity which has now been superseded by this Agreement. Under the Agreement, Everdura will manufacture Mistral VFBs to fulfil orders it intends to secure under the terms of the existing reseller agreement which targets more than 255 MWh of product sales over a three-year period. The Agreement states that Everdura will pay Invinity a royalty fee based on a material percentage of the sale price of any Mistral products sold.

Everdura will also utilise Invinity's existing supply chain and purchase cell stacks directly from the Company, which will continue to be manufactured by Invinity at its facilities in the UK and Canada. In addition, further to its December 2023 Year-End Business Update, Invinity's product development team has successfully undertaken initial performance testing of the first operating Mistral prototype. The Company is delighted to report that these tests have verified Mistral's fundamental performance targets and operating parameters.

This significant development milestone enables Invinity to conclude the development of production tooling, processes and procedures required for manufacturing and delivery of initial Mistral modules and to build towards the planned commercial launch of the product later this year. Separately to the above developments and in line with its 18 December 2023 announcement, the Board is very pleased with the level of interest shown in the Company by a number of potential strategic partners. Discussions with these parties are now at an advanced stage and continue to progress positively.

On this basis, the Company estimates that it should be in a position to conclude an agreement with one or more of these partners within approximately four to six weeks.
