OUTLOOK

In the short term, Invinity's team remains focused on a number of key
objectives:

1)   Deliver against our order book and close out the remaining commercial
contracts that underpin 2025 revenue forecasts.

2)   Continue to meet or exceed Endurium cost down programme targets in
order to enhance product margins and compete even more effectively in new and
existing markets.

3)   Progress our global expansion plans with partners and scale the
business operationally to be capable of delivering against gigawatt-scale
demand through 2027-30.

 

Evidence of the demand supporting this global expansion is increasingly
apparent across Invinity's core markets, demonstrated most recently by the
16.7 GWh of projects incorporating Invinity's Endurium batteries that have
been confirmed eligible for the UK Cap and Floor programme which target
deliveries (with associated revenue recognised) predominantly through 2028-30.
The Company is also actively engaged in comparable procurement schemes in the
USA and Canada and has received notification from a number of developers who
have submitted early-stage applications with Invinity's technology totalling
multiple gigawatt-hours for delivery across 2027-29 and beyond.

 

Strategically, Invinity is at a significant juncture in its corporate journey
with a technologically advanced product, a demonstrated track record of
delivery and operation, a leading market position within the vanadium flow
battery sector and a growing network of strategic partners across the world.
This capability is timely, as the Company has observed significant increases
in global interest in both long duration energy storage and non-lithium
battery solutions.

 

Building scale and reducing product cost are Invinity's key objectives as
global demand for LDES continues to accelerate. The Company anticipates the
start of the globalisation of its manufacturing operations over the next 12
months in regions including the USA, India and China and aggressively pursuing
improvements across our product, our processes and our people to successfully
transition our business into the next phase of its growth over the coming 5
years.

 

 

Jonathan Marren, Chief Executive Officer at Invinity said:

 

"The energy storage market is fast moving, innovative and growing
substantially. This creates significant opportunities as well as challenges
and to be successful we need to move and develop quickly. Acknowledging
revenue recognition is heavily H2-weighted and reflective of the launch of
Endurium only in late 2024, the achievements in the period and year to date
demonstrate the transformational progress we've made across our business in
the past 12 months. We remain on target to achieve a substantial improvement
in our 2025 FY results compared to last year while continuing to build deal
flow into 2026 and beyond.

 

"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."

2025 Interim Report

 

Invinity's achievements throughout the Period and in the year to date 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 Enterprise(TM), 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.

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.

Notes

(forming part of the unaudited consolidated historical financial information)

 

1 General Information

Invinity Energy Systems plc (the "Company") is a public company limited by
shares incorporated and domiciled in the UK. The registered office address is
Office 207, New Broad Street House, 35 New Broad Street, London EC2M 1NH.

 

On 9 January 2025, under a Scheme of Arrangement between Invinity Energy
Systems Limited ("former plc"), the former holding company of the Group, and
its shareholders, under Article 125 of the Companies (Jersey) Law 1991, and as
sanctioned by The Royal Court of Jersey, all the issued shares in former plc
were cancelled. In exchange, an equivalent number of new shares in former plc
were issued to Invinity Energy Systems plc in consideration for the allotment
to shareholders of one ordinary share in the Company for each ordinary share
in former plc that they held on the date of record, 8 January 2025.

 

The Company was incorporated under the Companies Act 2006 on 12 August 2024 as
a private company and re-registered on 3 January 2025 as a public company. The
introduction of a new Parent Company constitutes a Group reconstruction and
has been accounted for as a reverse acquisition under common control by
applying predecessor accounting in accordance with IFRS requirements. Although
the Group reconstruction did not become effective until 9 January 2025, the
Consolidated Financial Statements of the Company are presented as if the
Company had always been part of the Group with historical results combined
without recognition of goodwill. As the Company had no financial activity
prior to the scheme, the comparative consolidated financial statements for
prior periods remain unchanged. Earnings per share are unaffected by the
reorganisation.

 

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

 

The principal activities of the Company and its subsidiaries (together the
"Group") relate to the manufacture and sale of vanadium flow battery systems
and associated installation, warranty and other services.

 

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 2024.

 

Basis of Preparation

This unaudited condensed consolidated interim financial information for the
six-months ended 30 June 2025 (the 'interim financial information') has been
prepared in accordance with IAS 34, 'Interim financial reporting' as adopted
for use in the United Kingdom. The financial information should be read in
conjunction with the Group's annual financial statements for the year ended 31
December 2024 that were prepared in accordance with International Financial
Reporting Standards as adopted for use in the United Kingdom.

 

The annual report and financial statements for the year ended 31 December 2024
are available on the Company's website (www.invinity.com
(http://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 2024. 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 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 Information

The Group derives revenue from a single business segment, being the
manufacture and sale of vanadium flow battery systems and related hardware
together with the provision of services directly related to battery systems
sold to customers.

 

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.

Additional potential shares used in the calculation of diluted earnings per
share primarily relate to potential shares outstanding at 30 June 2025 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.

 

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 lower loss per share.

11 Business Combination

During the period, Invinity Energy (UK) Ltd. acquired a group of 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:

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.

Goodwill

All goodwill is tested 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.

The warranty provision represents management's best estimate of the 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.

24 Events Occurring After the Reporting Period

Subsequent to the reporting period, on 1 July 2025, the Group's subsidiary,
Invinity Energy (South Africa) (PTY) Ltd., was formally dissolved in
accordance with the requirements of the Companies Act 61 of 1973. No
adjustments have been made to the financial statements as at 30 June 2025 and
the Group is assessing the potential impact of the dissolution on future
period financial results.

 

On 11 July 2025, the Company announced it had entered into a licensing and
royalty agreement with UESNT, a manufacturer of vanadium electrolyte and
battery products based in China. Together, they have identified an opportunity
for vanadium flow batteries to provide large-scale, commercially viable energy
storage solutions in China. The Company will support UESNT in establishing
manufacturing capacity, reducing costs, and marketing Endurium in this key
market. Revenue and financial impact from this agreement will be recognised in
future periods.

 

On 1 August 2025, the Company announced it had received planning approval for
its LoDES project in the South East of England and confirmation of a £10m
grant from DESNZ, the maximum available. Of the total expected grant, £2.78m
has been received on 10 July 2025. The Project Grant Income of £2.78m has
been partially recognised within other items of operating income and expense.
The portion relating to future expenditure has been deferred and recorded
within other current liabilities.

 

In addition, on 1 August 2025, the Company announced it had received a formal
Notice to Proceed ("NTP") from STS Group in respect of a 10.8 MWh Endurium
battery system in western Hungary, supported by the European Union. Following
NTP, a downpayment is due, allowing manufacturing and order fulfillment to
commence ahead of shipment. There is no financial impact on current reporting
period. However, this event will positively impact revenue and cash flow in
future periods.

 

On 9 September 2025, the Company announced it had entered into conditional
subscription agreements with two new investors, Atri Energy and Next Gen
(together the "Subscribers"), to raise a total of £25m through the issue of
128,205,128 new Ordinary Shares at a price of 19.5 pence per share. The funds
will be used to enhance global manufacturing, diversify the Company's supply
chain, support product development and cost reduction, and strengthen working
capital for expansion.
