"the announcement last week that 21 projects representing 16.7 gwh of endurium batteries have been confirmed eligible for the uk cap and floor scheme was a very significant step forward and endorsement for invinity and endurium. were all of these projects to be awarded, we estimate up to 1,000 durable, high quality manufacturing jobs could be created in scotland if the scheme assessors apportion appropriate benefit to uk-manufactured technology solutions, sourcing from uk supply chains. alongside our partners, we will continue make this case strongly to ofgem, the uk regulator who is administering the scheme.   "we have also recently broadened our partnerships with a strategic investment from atri energy which will enable us to target opportunities commercially and operationally in india, and in china where we signed a partnership with uesnt and an mou with fortune 500 company, c&d group.   "our focus on continuing to reduce the product cost of endurium remains unwavering and i am delighted that we continue to advance ahead of our previous expectations in this regard. this shows considerable progress over the last 12 months and, as we build the foundation for success in the years to come, the overwhelming feeling is one of growing momentum."   stay up to date with news from

are representative of our talented team rising to the challenge of delivering against the five goals i set out twelve months ago when i became ceo. whilst our work to deliver success in each of these areas never stops, i'm pleased to report that twelve months on, we have achieved important progress against every goal (summarised below) and materially advanced the business as a result.   goal 1 - recognise fy24 revenue in line with analyst forecasts - achieved invinity delivered revenue in line with revised analyst forecasts for fy24.   goal 2 - launch endurium before 2024 year-end - achieved endurium product successfully launched with products shipped before 2024 year-end. in september 2025, the company launched endurium enterprisetm, a further expansion to invinity's product range catering specifically to commercial and industrial customers.   goal 3 - close deals from commercial pipeline to support volume ramp up - on track invinity's commercial team has built a £20m 2025 order book expected to convert to revenue and project grant income in the current year and is working to secure additional orders which will support revenue and cash generation in 2025 and beyond. highlights include: ·    new customer orders totalling 11.7 mwh signed during the period, representing a nearly three-fold increase year-on-year. ·    securing approval to proceed on the 20.7 mwh lodes project, expected to be the largest commercially operating vfb in europe once commissioned. ·    securing a follow-on 4 mwh order in september 2025 from hungarian partner ideona for delivery later this year.   additionally, the company has successfully originated and secured a number of important strategic projects and relationships in the year to date which are expected to significantly increase production volumes over the next 5 years. these include: ·    21 project bids confirmed eligible for the uk cap and floor scheme, representing 16.7 gwh of potential endurium demand primarily for delivery from 2028 - 2030. pending the successful outcome of these bids, this is expected to support a significant scale up of the company's manufacturing capacity from 2027 onwards and represent billions of pounds of future revenue. the company estimates it could create up to 60 permanent jobs for every gwh awarded, potentially as many as 1,000 if all projects were to proceed, noting that there is no guarantee of this due to the competitive nature of the process, details of which are set out in the 23 september 2025 announcement. ·    entry into the chinese energy storage market following the signing of a licence and royalty agreement with guangxi united energy storage new materials technology limited ("uesnt") in july 2025 and further expanded in september with the signing of an mou with xiamen c&d cooperation limited ("c&d"). ·    entry into the indian market through a strategic partnership with atri energy which targets commercial opportunities in the region as well as an expansion of manufacturing and supply chain capabilities in india.   goal 4 - further advance the cost reduction programme for endurium and incrementally improve product margins - achieved in the year to date, invinity's team have achieved a 43% reduction to date in the cost of endurium as compared against the previous vs3 product. furthermore, the company is currently tracking ahead of management expectations in respect of cost reduction, which targets substantial reductions year-on-year through 2030.   the company's new semi-automated stack production line is now operational at its bathgate facility, which has doubled stack production and improved quality, whilst recent strategic partnerships announced in asia are expected to generate further opportunities to accelerate cost reduction through economies of scale and scope.   goal 5 - review capital allocation across the business and drive operational efficiencies - achieved ongoing projects related to minimising corporate overheads while expanding business operations have already delivered a modest reduction in year-on-year administration costs while expanding business operations. further initiatives such as the rollout of a new erp system and improving our supplier development processes are expected to drive further efficiencies in the coming months.   note: whilst management believe that these goals have been achieved in the 12 month period as anticipated, each of goals 3, 4 and 5 remain a priority of the company to continue to advance.   financial performance   six months ended 30 june 2025 six months ended 30 june 2024 year ended 31 december 2024  £m £m £m revenue 0.3 1.6 5.0 gross loss (1.9) (1.1) (3.5) project grant income 1.8 - - loss for the period (10.0) (11.1) (22.8) property, plant and equipment plus intangible assets 27.0 25.7 26.3 total inventory and pre-paid inventory 14.1 6.4 8.2 net cash 18.7 46.2 32.3 net assets 55.7 77.3 65.7   noting the significant uptick in h1 signed orders year-on-year, revenue recognition is again expected to be heavily h2 weighted in 2025 with maximum potential revenue & project grant income for the current year of £25.0m.   the company recognised £2.0m of revenue and project grant income in h1 (h1 2024: £1.6m) as part of a £20m order book of signed contracts to deliver against by the end of the year. the company is also in the final negotiation stage on contracts which could contribute approximately £5m of 2025 revenue, should negotiations be successful and final documentation executed in a timely fashion. management also notes that in the event that licence and royalty fees are recognised as anticipated from the agreement signed with uesnt in july 2025, this would likely have a significantly positive impact on net income.   loss from operating activities reduced to £10.2m (h1 2024: £11.4m) supported by a moderate reduction in administrative expenses, and the recognition of £1.8m project grant income received under the lodes project for which cash has since been received. within cost of goods sold, unabsorbed overheads of £0.9m reflect lower production volumes in h1 as the company transitioned from the vs3 to endurium product, and an increase in warranty costs which includes direct current voltage converters ("dc:dcs") that are being replaced by the supplier in h2. taken together, the loss for the period reduced to £10.0m (h1 2024: £11.1m).   inventory and prepaid inventory increased to £14.1m (h1 2024: £6.4m) in order to deliver against customer contract and project deliveries forecasted for h2 2025. cash at 30 june was £18.7m, which has increased to £39.7m at 29 september reflecting the total £25m strategic investment by atri energy and next gen which was approved by shareholders yesterday. the company remains debt-free (excluding leases).   commercial outlook the commercial revenue and project grant income outlook for the full year 2025 as at 30 september 2025 comprises the following:   commercial revenue and project grant income 2025 £m   order book 20 near-term contracts 5 development pipeline - maximum potential revenue & project grant income (based on above) 25   where: ·    order book includes signed contracts expected to generate revenue in the relevant year that have either been delivered (and revenue recognised), are in the fulfilment phase or are awaiting notice to proceed ("ntp"). invinity has higher confidence in assessing the timing of delivery and revenue for these projects, although risks related to supply chain, fulfilment and/or receipt of ntp remain. ·    near-term contracts includes projects where the customer has indicated an intent to proceed, and where final contracting is underway. invinity has lower confidence in assessing the timing of delivery and revenue for these projects as risks related to final negotiation and documentation remain. ·    development pipeline includes projects where the customer has engaged invinity in a procurement process, submitted invinity's products to a public procurement scheme or applied for relevant permits. revenue is expected to be recognised in the relevant year, however both commercial and development risks remain.     jonathan marren chief executive officer   unaudited financial results for the period ended 30 june 2025   unaudited consolidated statement of profit and loss for the six

consistently applied across all group entities for the purpose of producing this interim financial information.   the financial information included in this document does not constitute the company's statutory accounts within the meaning of section 434 of the companies act 2006. the comparative figures for the financial year ended 31 december 2024 represent the company's statutory accounts for that year, which were prepared under the companies (jersey) law 1991, reported on by the company's auditors, and delivered to the jersey financial services commission.   the statutory accounts for the year ended 31 december 2024 received an unqualified audit report under the companies (jersey) law 1991. statutory accounts for subsequent financial periods will be prepared and filed in accordance with the companies act 2006 with the registrar of companies in england and wales.   the group's business activities, together with factors likely to affect its future development, performance and position, are set out in the operations and financial review sections of this report.   the financial position of the group, its cash flows and liquidity position are described in the financial review section.   going concern the directors are satisfied that the group has adequate resources to continue to operate as a going concern for the foreseeable future and that no material uncertainties exist which could cause significant doubt with respect to this assessment. in making this assessment, the directors have considered the group's balance sheet position and forecast earnings and cash flows for the period from the date of approval of these financial statements to 30 september 2026.   the group has relied on fundraising in previous years. following the completion of a strategic investment of £25m by atri energy and next gen announced on 9 september 2025, the group significantly strengthened its liquidity position. the group held cash of £18.7m as at 30 june 2025 (30 june 2024: £49.2m).   as part of the going concern assessment the directors have prepared a cash flow forecast which indicates that the group would expect to remain cash positive during this period and without the requirement for further fundraising. the business continues in a cash outflow position, using funding generated from previous fundraises. however, it plans to move to a cash inflow position upon the launch and delivery of material volume of the next generation product.   this cash flow forecast was stress-tested for a worst-case scenario of no positive cash receipts from sales. in these tested scenarios, the business would remain cash positive for the 12 months from the date of approval of these financial statements.   therefore, the directors believe it is appropriate to prepare the accounts on a going concern basis.   3 critical accounting judgements and key sources of estimation uncertainty the preparation of interim financial information requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets and liabilities and of items of income and expense. actual results may differ from these estimates.   in preparing this interim financial information, the significant judgments made by management in applying the group's accounting policies were the same as those that applied to the consolidated financial statements for the year ended 31 december 2024. similarly, the key sources of estimation uncertainty related to the financial information were the same as those encountered when applying the group's accounting policies in relation to the preparation of the consolidated financial statements for the year ended 31 december 2024.   in preparing the condensed consolidated financial information, management is required to consider the principal risks and uncertainties facing the group. in management's opinion the principal risks and uncertainties facing the group are unchanged since the preparation of the consolidated financial statements for the year ended 31 december 2024. those risks and uncertainties, together with management's response to them are described in the risk review section of the annual report and financial statements for the year ended 31 december 2024.   4 revenue from contracts with customers and income from government grants segment

included in calculating diluted earnings per share.   where additional potential shares have an anti-dilutive impact on the calculation of loss per share calculation, such potential shares are excluded from the weighted average number of shares used in the calculation.   additional potential shares are anti-dilutive where their inclusion in the calculation of loss per share results in a

four companies where invinity energy (uk) ltd. holds 100% of the equity in invinity energy bess holdings ltd.; invinity energy bess holdings ltd. owns 100% of the equity in uckfield bess ltd.; uckfield bess ltd. holds 100% of the equity in uckfield energy centre ltd.; uckfield energy centre ltd. holds 100% of the equity in uckfield solar electric forecourt ltd. consequently, the group exercises full control over each subsidiary through successive, direct ownership at each level. the total consideration paid for the acquisition was £300,000.   on 31 march 2025, the acquisition date, the consideration given was allocated to the fair value of assets acquired and liabilities assumed or discharged based on their assessed fair values. the fair value of the total consideration was allocated as follows:   assets acquired and liabilities assumed at 31 march 2025  fair value £'000 non-current assets  property, plant and equipment 197 right-of-use asset 847 current liabilities  lease liability (10) non-current liabilities  lease liability       (734) net identifiable assets acquired 300 goodwill - consideration for acquisition of forecourt 300   fair value adjustments made property, plant and equipment relates to assets under construction for the development of a 20.7 mwh vanadium flow battery system ("vfb bess project") at the group's uckfield location in the south east of england. given the early stage of development of the project, the group recognised the fair value of expenditures incurred up to the acquisition date rather than the fair value of the project as a whole.   the right-of-use asset was subject to a purchase price allocation (ppa) uplift due to qualitative factors identified during the acquisition. these included the strategic location of the site, proximity to a grid connection substation, a successful planning application, and an agreement in place to construct necessary infrastructure. as a result, the carrying value of the right-of-use asset was increased by £132,684 as part of the acquisition accounting. this uplift is being amortised over the remaining lease term and depreciation is capitalised until asset is available for use.    the lease liability represents the group's interest in leased land designated as the site for the vfb bess project. the fair value of the lease liability has been determined to be equivalent to its carrying value. this assessment reflects the terms of the lease which include annual inflationary adjustments tied to the consumer price index. additionally, the lease liability was remeasured at the acquisition date to incorporate an updated incremental borrowing rate and revised management assumption regarding the lease extension option.     goodwill in the business combination the fair value of the identifiable net assets acquired was equal to the total consideration transferred and no goodwill was recognised.   this reflects that the purchase price was fully absorbed by the fair value of the identifiable net assets acquired, and no intangible future economic benefits beyond those assets and liabilities were identified at acquisition.   revenue and profit contribution the acquired group contributed no revenue or profit to the consolidated group for the period from 31 march 2025 to 30 june 2025.   if the acquisition had taken place on 1 january 2025, consolidated pro-forma revenue and net loss for the period ended 30 june 2025 would have been unchanged from the reported consolidated revenue and net loss for the period.   12 goodwill and intangible assets  goodwill

annually for impairment. at 31 december 2024, goodwill was tested for impairment using the fair value less cost of disposal method. the closing share price on 30 june 2025 was 23.75 pence giving a market capitalisation of £104.6 million which is more than £48.8 million higher than the net assets value of the company on this date. the share price would need to have dropped below 12.65 pence for the market value to be below the net asset value of the company at that date. based on the above, no impairment loss was identified in relation to goodwill.   patents and certifications there have been no events or circumstances that would indicate that the carrying value of patents and certifications may be impaired at 30 june 2025.   13 property, plant and equipment  computer and office

costs anticipated to be incurred related to warranty claims, both current and future, from customers in respect of goods and services sold that remain within their warranty period. the estimate of future warranty costs is updated periodically based on the company's actual experience of warranty claims from customers.   the element of the provision related to potential future claims is based on management's experience and is judgmental in nature. as for any product warranty, there is an inherent uncertainty around the likelihood and timing of a fault occurring that would cause further work to be undertaken or the replacement of equipment parts.   a standard warranty of up to two years from the date of commissioning is generally provided to customers on goods and services sold and is included in the original cost of the product. customers are also able to purchase extended warranties that extend the warranty period for up to a total of ten years.   provision for contract losses a provision is established for contract losses when it becomes known that a contract has become onerous. a contract is onerous when the unavoidable costs of fulfilling the group's obligations under a contract are greater than the revenue that will be earned from it.   the unavoidable costs of fulfilling contract obligations will include both direct and indirect costs.   the creation of an additional provision is recognised immediately in profit and loss. the provision is used to offset subsequent costs incurred as the contract moves to completion.   18 trade receivables  30 june 2025

receivables are amounts due from customers for sales of vanadium flow battery systems in the ordinary course of business. trade receivables do not bear interest and generally have 30-day payment terms and therefore are all classified as current.   an allowance for potential credit losses of £nil (2024: £nil) has been recognised.   19 cash and cash equivalents  30 june 2025 30 june 2024 31 december
