Update on Strategic Investor Discussions

Invinity Energy Systems plc (AIM: IES) (AQSE: IES) (OTCQX: IESVF), a leading global manufacturer of utility-grade energy storage, is pleased to provide the following update on its discussions with strategic investors.

The Company has made significant progress towards securing a material investment from multiple strategic partners who have each completed comprehensive due diligence on Invinity and are now working towards finalising binding investment agreements. Invinity is extremely pleased that this includes a proposed investment by a Tier 1 investor which, if concluded, will materially enhance the Company's business and reputation in both the UK and internationally.

The Directors believe that this proposed investment has stimulated further interest from other high quality strategic partners who have all indicated their willingness to proceed with an investment and are currently in the process of concluding their approval processes, which have taken slightly longer than anticipated due to the challenge of coordinating negotiations with multiple partners across different jurisdictions. While there can still be no certainty that all, or any, of these parties will complete their planned investment in Invinity, the Company expects to finalise investment agreements with these partners in the coming weeks.

Invinity views strategic relationships as a key part of the Company's strategy to grow market share within core markets and continue implementing a licencing and royalty-focussed growth programme in other markets, as evidenced by the agreement with Everdura announced 26 February. This strategy will allow the Company to remain capital light and generate significant cash flows as it grows globally whilst retaining tight ownership of its core intellectual property and securing a leading position within its home markets.

A further announcement will be made as soon as practical.
