("Invinity" or the "Company")

Official Opening of New Manufacturing Facility in Scotland

Successful capital markets event held for investors and key stakeholders

Invinity Energy Systems plc (AIM: IES) (AQSE: IES) (OTCQX: IESVF) a leading global manufacturer of utility-grade energy storage, is delighted to announce that in line with plans set out in the Company's 3 June 2024 announcement, its new Motherwell manufacturing facility was officially opened yesterday.

This facility, located in Motherwell, North Lanarkshire is approximately six times the size of Invinity's existing facility in Bathgate and will increase the Company's UK assembly capacity to over 500 MWh per year, support the creation of more than 40 new jobs in the region and enable faster and more efficient delivery of vanadium flow batteries across the UK, Europe and further afield.

This achievement underlines the progress Invinity is making as part of its capex-light manufacturing strategy to ensure it can meet the more than 6 GWh of global demand currently in the Company's commercial pipeline. Supported by the UK Infrastructure Bank's recent investment into the Company alongside institutional and retail investors and the UK Government's growing focus on longer duration energy storage, Invinity is well-placed to ensure its batteries can be rapidly manufactured and deployed to help accelerate the country's transition to net zero.

Following the official launch, the Company hosted a Capital Markets Day for investors, analysts and key stakeholders including representatives from the Scottish Government at its Motherwell and Bathgate facilities. The event was well attended and included a tour of both facilities with opportunities to meet with Invinity's Board of Directors and hear from Invinity staff and partners through a number of 'deep dive' sessions. This included a live demonstration of Invinity's batteries charging and discharging from the Scottish grid and an overview of the Company's next-generation product, codenamed "Mistral" for which the pilot manufacturing stage has been initiated ahead of commercial launch later this year.

The Company is in the process of producing a recording of the event which will be made available on Invinity's website in due course.

Larry Zulch, Chief Executive Officer at Invinity said:

"Our Motherwell facility supports key pillars of Invinity's strategy: our transformation of vanadium flow batteries from bespoke engineering projects into factory-built products, with all of the benefits of quality, cost, and consistency derived therefrom, combined with our ongoing commitment to the UK market at every level from manufacturing through to deployment. We were pleased to share the opening of this facility with our investors and stakeholders participating in our very successful Capital Markets Day."
