Outlook

During the remainder of 2024 we plan to deliver against the near-term corporate goals and set in place the foundations for 2025 and beyond. We believe Long Duration Energy Storage remains critical to increasing the penetration of renewable energy and in advancing the path to net-zero - this is not capable of being achieved by lithium alone. Vanadium flow batteries remain, in our view, the most credible and advanced such alternative and if we can deliver on our corporate goals, the market opportunity remains very significant.

Invinity's executive team has set the following corporate goals to achieve within the next 12 months:

• Ship remaining VS3 orders to support revised 2024 year-end revenue forecasts;
• Launch the Mistral product for general sale before 2024 year-end;
• Close deals from commercial pipeline to support volume ramp in line with forecasts;
• Further advance the production cost reduction programme for the Mistral product and incrementally improve product margins across 2025 and beyond; and
• Review capital allocation across the business and drive operational efficiencies

Jonathan Marren, Chief Executive Officer at Invinity said:

"I have spent much of the past three weeks since my appointment as CEO meeting with our staff, customers and investors and it is clear there is enormous opportunity for our business. This was reinforced this week during many conversations with potential customers at the Solar and Storage Live trade show in Birmingham, where they see Invinity as the natural choice when considering the future role that LDES will play in the UK and the implementation of the long-awaited LDES cap and floor mechanism.

"There will be inevitable challenges to overcome as well but I am reassured that the launch of our next-generation product remains on track, further underlined by the sale announced today which we anticipate will be the first Mistral product to ship. This is an important achievement and gives me confidence in delivering on the five corporate priorities I've set out to achieve over the next 12 months. I look forward to updating on further positive progress in these areas before year end."

Chairman's Statement

Three days from now, Ratcliffe-on-Soar power station is set to shut down for the final time and the UK will no longer be powered by coal. This notable event underlines the UK's commitment to a cleaner electricity grid which, allied with the rapid increase in solar, wind and energy storage deployments, demonstrates that the transition to net zero is achievable and moving ahead at pace.

This example of leadership in decarbonising power production is helping to provide the necessary foundations for future clean economies around the world. Invinity has a crucial role to play in making 24/7 renewable energy a reality and we are grateful for the leaders who have played their role in our story to date, in particular, Larry Zulch, who as CEO was instrumental in guiding the Company to become a global leader in the field of modular flow batteries. For this we thank him and wish him all the best in his retirement.

Significant change can be challenging, but I am delighted that Jonathan Marren agreed to take over the leadership of the Company. As Chief Development Officer and then also as Chief Financial Officer, Jonathan has had a significant impact on the financial and strategic side of the business, not only improving operational and financial efficiencies across the whole Company but also securing vital strategic partnerships including the backing of UK Infrastructure Bank. As the new CEO, Jonathan's task now is to steer the Company towards profitability as a self-sustaining business and has set out five key priorities which signpost the way. Jonathan's appointment signals a new era for Invinity and the Board and I have every confidence that, with the support of Matt Harper as Chief Commercial Officer and the whole Invinity team, he will succeed.

Non-Executive Chairman

Chief Executive Officer's Report

I assumed the role of CEO three weeks ago and have spent much of this time speaking with our staff, shareholders, partners and customers. From these conversations, what is clear is that whilst the impact of short-term timing issues is clearly disappointing and reflected in the current share price, the medium- and long-term fundamentals underpinning our business remain unchanged. We have developed a competitive product, proven its abilities in customer operation around the world and manufactured and delivered more than 1,000 battery modules. The opportunity remains significant and my key priority is implementing steps immediately to ensure we can capture it and restore value to our shareholders whilst making a positive impact on the energy transition.

The key short-term priorities for the business include addressing delays in closing commercial deals in the year to date and completing the production cost reduction exercise on Mistral. Although we stated in May that revenues were likely to be significantly weighted towards H2 2024, the risk of these revenues being further pushed into 2025 has become increasingly likely as we announced in the trading update on 6 September.

As we set out in the trading update, the fundraise in May this year has provided Invinity with capital to achieve profitability. Demand for our next-generation Mistral product remains strong and supportive policy that encourages longer duration energy storage provides exciting upside for our business in our core markets.

In the trading update I set out a number of areas in which I promised to highlight progress on at the announcement of our H1 results. I'm pleased to report the following:

We have in recent weeks significantly enhanced the capabilities of our Commercial team. We have added a new Director of Market Intelligence who brings to the team significant expertise in UK and European energy markets and is already providing deeper analytical capabilities to better inform commercial targeting. We have also taken steps to enhance our regional capabilities in Invinity's core UK and U.S. markets. Our new Head of Sales for the UK and Europe brings over 25 years of sales experience with leading global energy and energy services companies to bear in accelerating deal flow. Our recently hired Vice President of Business Development will help refine the Company's longer-term commercial strategy while enhancing relationships with key stakeholders such as the UK's Department for Energy Security and Net Zero ("DESNZ") and the U.S. Department of Energy ("DOE"). I will be monitoring this area of the business closely in the coming months.

Operationally, a new semi-automated stack production line is now on order and expected to be operational at our Bathgate facility during H1 2025. This is in line with the plans we set out during our fundraise in May this year and is expected to result in a material reduction in stack production costs. In the past week we have secured approval to use the "Made in Britain" mark on our UK-manufactured products - this recognition underlines our commitment as a UK domestic battery manufacturer and we believe this positions us well for the future. Additionally, discussions are advancing positively in the U.S. with a number of partners across our supply chain and our intention remains to achieve domestic content requirements in the U.S. in time for Mistral volume production.

We will continue to make important progress on these areas outlined above but in the medium- to longer-term, my focus as CEO is to ensure Invinity delivers for all its stakeholders and rewards the support we have received to date. As such, my priorities for the next 12 months are to:

• Ship remaining VS3 orders to support revised 2024 year-end revenue forecasts;
• Launch the Mistral product for general sale before 2024 year-end;
• Close deals from commercial pipeline to support volume ramp in line with forecasts;
• Further advance the production cost reduction programme for the Mistral product and incrementally improve product margins across 2025 and beyond; and
• Review capital allocation across the business and drive operational efficiencies.

I look forward to providing further updates as we advance in each of these areas.

H1 2024 Financial Results

The £1.6m total income, including sales revenue and project related grant income (H1 2023: £14.8m), refers primarily to the delivery of the 2.1 MWh project for OPALCO as well as other associated revenues from projects in our core geographies of North America, the UK, Europe and Australia in the Period.

The £11.4m operating loss (H1 2023: £12.6m) incorporates an improved gross loss position of £1.1m (H1 2023: £3.3m) in the Period alongside a small increase in Administrative Expenses to £10.3m (H1 2023: £9.3m) relating primarily to payroll costs and research and development costs.

Finance income and finance costs relates to interest received on cash balances held as a result of the equity funding secured during the period.

Total inventory and pre-paid inventory of £6.4m relates to projects expected to be delivered by the end of 2024 as follows. Net related working capital at the end of the period is £4.8m (H1 2023: £4.7m) as a result of the sales activity.

During the Period, the Company raised £57.4m from an equity fundraising including a £25m strategic investment from UK Infrastructure Bank. The Company remains debt-free excluding leases.

Commercial and Operational

During the Period, Invinity closed 4 MWh of new VS3 sales (H1 2023: 5.4 MWh of VS3 sales). 6.2 MWh of batteries were manufactured, of which 2.1 MWh were delivered with the balance expected to be shipped by year end.

The Period also included significant milestones enhancing the Company's position in the global energy storage market. In January, the Company was recognised by BloombergNEF as the world's first non-lithium Tier 1 battery supplier - a significant achievement. In March, our Chairman Neil O'Brien attended a high-profile launch event, at which the Belgian Minister for Energy was present, of the Invinity VFB system owned by Equans Belgium and delivered in partnership with European heavyweight customers Engie Belgium and Jan De Nul.

Since last reported in June, the Company's commercial pipeline remains materially unchanged. Invinity continues to receive strong qualified interest in its products from customers across the world, enhancing Management's confidence in the Company's commercial prospects. Closing further deals, in addition to the 1.2 MWh order announced today, remains a key priority for the Commercial team.

To this end, tripartite discussions on the LODES project between Invinity, a major international renewable energy project developer and DESNZ are progressing strongly, with the parties actively engaged in finalising the project's structure and contracts. The large-scale DOE-funded deals first announced in September 2023 also continue to progress positively, the closure of which are a key priority for Invinity's new U.S.-based VP of Business Development.

The Company recently presented details of the first of these DOE-funded projects, to be located at the Pacific Northwest National Labs ("PNNL"), at the DOE's annual Energy Storage Grand Challenge Summit alongside the PNNL programme lead. The Company was also pleased to note the visit by DOE Loan Programs Office ("LPO") director Jigar Shah to partner Indian Energy's project at the Viejas Resort and Casino in California, where 44 VS3s with a total capacity of 10 MWh are now installed and commercial operation is expected before the end of 2024.

The Company continues to evolve its engagement with partners in non-core markets, including its relationship with Taiwanese partner Everdura. Together, the companies are progressing towards certification of Mistral for the Taiwanese grid, a key requirement for large national battery procurement programmes expected in 2025. Invinity and Everdura are also progressing operational plans for the delivery of Invinity products in the context of the Company's license and royalty model, whereby Invinity will benefit from Everdura's enhancing local competitiveness by using domestic supply chains, assembly facilities and support services.

Without accounting for any other deals within Invinity's existing pipeline, the potential revenue contribution from the LODES project (match-funded, but yet to close) and the 14.4 MWh order from Everdura (closed in September 2023) substantially covers 2025 revenue forecasts, with the aforementioned DOE projects representing a material portion of 2026 revenue.

Policy & Government Engagement

During the Period, there were a number of strong policy developments in support of long duration energy storage. This included the launch of a consultation in January by DESNZ for a Cap and Floor mechanism to support the UK LDES market which specifically excludes lithium-ion. Additionally in March, the House of Lords Science and Technology Committee, led by Baroness Brown, published its report titled "Get on with it" that looked at the importance of long duration energy storage in the UK and quoted evidence provided by Invinity to the Committee's enquiry into long duration energy storage for the UK grid. Finally, Invinity continued its work engaging with policymakers in its core markets, of which a particular highlight during the Period was Matt Harper's policy roundtable with David Eby, Premier of British Columbia, Canada.

Post-Period, the Company held a Capital Markets Day for shareholders and investors and two further visits for Cabinet Ministers from the Scottish and UK Governments at its new Motherwell facility which provides enhanced manufacturing capabilities to Invinity ahead of the next-generation product launch later this year. These visits are a continuation of the Company's strong government engagement that is of increasing importance as LDES policy in the UK and elsewhere continues to progress.

Next-Generation Product

Invinity's next-generation product development programme continues to advance with the support of the Company's development partner and a number of pilot customers. The Mistral production prototype is currently connected to the grid at Invinity's product development centre in Vancouver, Canada and has not only achieved performance targets, but has exceeded technical expectations in certain areas.

Commercial launch, which will see the product offered for general sale by Invinity, will occur by the end of this year. Although volume rollout of the product will now occur later in 2025, the first shipment of the Mistral product is still expected to occur on schedule. To this end, the Company is pleased to announce the sale of a 1.2 MWh Mistral battery system to Gamesa Electric, details of which are disclosed above.

In parallel with the Mistral commercial launch and first customer delivery, Invinity is advancing plans for a cost reduction exercise as announced in the Company's Trading Update of 6 September 2024. Initiatives already underway expect to deliver reduced product costs through both design improvements and enhanced supplier efficiencies. Design improvements include changes to decrease part count and simplify assembly procedures. Supplier efficiencies will be achieved by evolving manufacturing of high-value components from one-off bespoke production to methods suitable for higher volume, while transitioning from flexible but low-volume localised suppliers to global best-cost regions suitable for delivering significant production volumes.

Corporate and Strategic

The Company's relationship with Taiwanese partner Everdura took a further step forward with the signing of a strategic manufacturing agreement in February. This agreement will see Everdura market and sell Invinity products in Taiwan and other markets under its existing reselling agreement with the Company. Everdura will manufacture Mistral VFBs, purchasing cell stacks directly from the Company, and Invinity will be paid a royalty fee based on a material percentage of the sale price of any Mistral products sold.

In addition to advancing its strategic relationship with Taiwanese partner Everdura, covered in detail in the Commercial and Operational section above, the Company secured significant financial backing from two further strategic partners in the May 2024 fundraise, being UK Infrastructure Bank, which has provided £18m of ringfenced capital to support the deployment of LDES projects within the UK, and Korea Investment Partners. Part of UKIB's investment also includes a Board position that will support the Company's ongoing governance and development as well as provide valuable financial expertise.

In May 2024 Invinity stated its commitment to redomicile the Company back to the UK. The Company confirms this process is underway and is expected to complete early in the new year.

The Company is quoted on the AIM Market of the London Stock Exchange with the ticker symbol IES.L, on the AQSE Growth Market in the United Kingdom with the ticker symbol IES and on the OTCQX Best Market in the United States of America with the ticker symbol IESVF.

2 Accounting Policies

The accounting policies applied in this condensed consolidated financial information are consistent with those applied in preparing the financial statements for the year ended 31 December 2023.

Basis of Preparation

This unaudited condensed consolidated interim financial information for the six-months ended 30 June 2024 (the 'interim financial information') has been prepared in accordance with IAS 34, 'Interim financial reporting' as adopted by the European Union. The financial information should be read in conjunction with the Group's annual financial statements for the year ended 31 December 2023 that were prepared in accordance with International Financial Reporting Standards as adopted by the European Union.

The annual report and financial statements for the year ended 31 December 2023 are available on the company's website (www.invinity.com).

This interim financial information has been prepared using the historical cost basis of accounting. The accounting policies applied across all the Group's subsidiaries when preparing the financial information are consistent with those adopted and disclosed in the annual financial statements for the year ended 31 December 2023. The accounting policies have been consistently applied across all Group entities for the purpose of producing this interim financial information.

The financial information included in this document does not comprise statutory accounts within the meaning of Companies (Jersey) Law 1991. The comparative figures for the financial year ended 31 December 2023 are not the Company's statutory accounts for that financial year within the meaning of Companies (Jersey) Law 1991. Those accounts have been reported on by the Company's auditors and delivered to the Jersey Financial Services Commission.

The report of the auditors included in the annual report and financial statements for the year ended 31 December 2023 was unqualified.

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 June 2025.

The Group has relied on fundraising in previous years and following the completion of successful fundraising in May 2024, the Group had cash of £49.2 million as at 30 June 2024 (30 June 2023: £12.9 million).

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.

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 2023. 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 2023.

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 2023. 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 2023.

4 Revenue from Contracts with Customers and Income from Government Grants

Segment Information

The Group is organised internally to report on its financial and operational performance to its chief operating decision maker, which has been identified as the Executive Directors as a group.

All revenues were derived from continuing operations.

Revenue from Contracts with Customers

Grant Income other than Revenue

The Group receives grant income to help fund certain projects that are eligible for support, typically in the form of innovation grants. The total grant income that was received in the period was as follows:

9 Loss per Share

The weighted average number of shares used to calculate basic and diluted loss per share as presented in the consolidated statement of comprehensive loss was as follows:

Additional potential shares used in the calculation of diluted earnings per share primarily relate to potential shares outstanding at 30 June 2024 that may be issued in satisfaction of 'in-the-money' employee share options. Potentially dilutive shares related to 'in-the-money' outstanding warrants to subscribe for ordinary shares in the Company are also included in calculating diluted earnings per share.

Additional potential shares are anti-dilutive where their inclusion in the calculation of loss per share results in a lower loss per share.

10 Cash Flows from Operating Activities

Goodwill

All goodwill is tested annually for impairment. At 31 December 2023, goodwill was tested for impairment using a fair value less costs of disposal methodology by reference to the Company's quoted market capitalisation using the price of 35.0 pence per share at that date. No impairment loss was identified in relation to goodwill.

The closing share price on 25 September 2024 was 9.25p, giving a market capitalisation of £40.53m which does not indicate impairment of 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 2024.

12 Property, Plant and Equipment

The Group has no assets pledged as security. No amounts of interest have been capitalised within property, plant and equipment at 30 June 2024 (2023: £nil).

13 Inventory

The amount of revenue recognised in the period that was included in contract liabilities at the end of the prior year was £203,997 (2023: £8,097,770).
