Invinity Energy Systems (AIM:IES), in its financial results for 2025, said it is expecting to see accerlerated growth.
In terms of numbers, the company reported combined Revenue and Other Income of £8.7m and Project Grants of £9.1m, totalling £17.8m for the year ended 31 December 2025, a 256% increase versus 2024.
Revenue growth was accompanied by a sixfold rise in sales to 31.4 MWh (504% YoY), product shipments of 24.9 MWh (241% YoY), a narrowing gross loss to £2.9m (2024: £3.5m), and a year-end cash balance of £28.8m with the Group remaining debt free (2024 cash: £32.4m).
"The results reflect a business that has deliberately invested in its foundations and is now clearly entering a new phase of accelerating growth," Chief Executive Jonathan Marren said.
The company, a manufacturer of vanadium flow batteries, highlighted commercial progress, including its first Endurium Enterprise sale, inclusion of 16.7 GWh across UK LDES Cap & Floor bids and a track record of 9 GWh dispatched by deployed products.
Post-period milestones include selection to design up to a 1.5 GWh VFB for FlexBase in Switzerland, completion of VFB deliveries to the Copwood VFB Energy Hub in May 2026 and a 2 MWh sale to a US Department of Energy-funded C&I project in Wisconsin.
Management said it is on target to achieve a forecast minimum 66% reduction in unit costs for Endurium versus the VS3 product within two years, with much of the programme completed ahead of schedule.
