INTRODUCTION

Invinity, proven grid-scale  
energy storage

We are surrounded by energy storage. There are batteries in our phones, 
computers, watches, cars, and, now, on the electric grid. The problem is 
that the battery technology that works so well in our pockets doesn’t work 
as well at grid scale; it wears out, limits use, and even catches fire. An 
alternative is required, and Invinity provides that alternative.

Invinity’s batteries are the size of shipping containers. They’re big, heavy 
and cost a bit more, but they don’t wear out, they can’t catch fire, and 
they can be operated continuously from full charge to full discharge for 
25 years. Built as a standardised product in a factory, our vanadium flow 
batteries transform a technology proven for decades from an engineering 
exercise into a vital part of the energy transition.

Invinity has 75,000 kilowatt-hours of its modular battery systems deployed 
or contracted for delivery to 82 projects across 18 countries – more than 
any other company in our space. We’ve deployed the largest flow battery 
systems in the U.S., Canada, Australia and the UK, our shareholders include 
the UK Infrastructure Bank alongside some of the world’s leading institutional 
investors and our customers include the U.S. Department of Energy, the UK 
Government and some of the world’s largest multinational energy companies.

Invinity is a global business with operations in the UK, Canada, the U.S., 
Australia and China. The Company is quoted in the UK on AIM and AQSE 
and trades in the U.S. on OTCQX.

Introduction
Foundations for Scale

An	unprecedented	level	of	attention	and	capital	is	flowing	
towards building a net zero grid by the customers, regulators 
and grid operators who make up global electricity markets. 

Matt Harper
Chief Commercial Officer

Wind and solar power are the least-cost form of generation 
almost everywhere. Markets that can take that low-carbon 
electricity and deliver it to users reliably and at low cost are 
the focus of policymakers worldwide. This is the opportunity 
on which Invinity is focused.

Over the past two years, the Invinity team has delivered ever-
larger projects – proving how our vanadium flow batteries can 
deliver the capabilities our customers want: durable, safe, long 
duration energy storage (“LDES”). With the launch of our next-
generation vanadium flow battery, code-named “Mistral”, expected 
later this year we will have the product that can deliver those 
capabilities to electric grids around the world at any scale. 

This combination of opportunity and capability in markets around 
the world are Invinity’s “foundations for scale”. As we look 
forward, we see tremendous opportunity from those foundations. 
Invinity will go from strength to strength by proving at increasing 
scale the benefits of durable long duration storage. If we do that 
job right, we believe our products will fundamentally inform the 
structure of, and be widely deployed across, the global energy 
system for decades to come.

Market Headwinds and Tailwinds
Tremendous commercial opportunities are emerging on the path 
to net zero. First and foremost, renewables are the world’s lowest 
cost source of new electric generating capacity. This is reflected in 
the massive solar farms being built from northern Canada to Dubai 
and the wind farms now serving Micronesia to northern Scotland.

However, headwinds are beginning to appear. In jurisdictions like 
California and Australia that have a large proportion of photovoltaic 
generating assets, negative electricity market prices are becoming 
common at peak solar generation times, challenging the 
economics of expanding such generation. More solar also means 
that fuel-powered generators are operating fewer hours per day, 
lowering asset utilisation and thus pushing up costs for peaking 
capacity. Even conventional low carbon sources are struggling: 
from Canada to Australia, hydro projects are taking longer and 
costing more, as are recent nuclear plants in the UK and U.S.

Fortunately, energy storage assets are increasingly proving their 
ability to “firm up” the output from intermittent renewables. Batteries 
are now meeting a significant portion of demand in some high 
renewables markets. LDES solutions promise to further extend the 
benefits of renewables when the sun isn’t shining and the wind isn’t 
blowing. Even in jurisdictions like California, the largest batteries in 
the world are only starting to fill in where solar power cuts off.

If batteries are going to facilitate an even higher proportion of 
our energy needs being served by renewables, critical questions 
remain: what kind of batteries will serve not just peak hours but 
power our businesses and homes 24 hours per day? How much 
capacity is required? Where should it be installed? And who will 
pay for it? 

Fortunately, Invinity is already helping to answer these questions. 
Our batteries are ideally suited for a 24-hour non-stop cycle 
shifting solar overnight, doing so for the life of the generating asset 
and with a chemistry safe enough to be installed alongside homes 
and critical infrastructure. Additionally, our team are actively 
engaging with policymakers and regulators worldwide to ensure 
their plans contemplate these advantages, seeding markets for the 
revenue and profits that will see our business grow and thrive.

The UK: Less Sun, More Wind but Similar Challenges  
to California
The UK’s transition towards a net zero grid saw a massive 
inflection point this winter, with wind outstripping fossil fuel 
generation in consecutive quarters for the first time ever. 
However, the UK battery market has struggled. Revenues for 
UK-based battery assets dropped significantly over the course 
of 2023, presenting challenging economics for asset operators 
and developers alike. 

We’ve also seen significant delays in permitting and grid 
interconnection, which have been particularly challenging in the 
context of our LODES project, which was awarded funds by the 
UK Department of Energy Security and Net Zero (“DESNZ”). 
Fortunately, as regulations adapt to the benefits that batteries 
can deliver to the grid, and as local planning councils awaken to 
the safety benefits of our flow batteries over lithium alternatives, 
we are seeing individual projects accelerate. 

The broad economic picture is improving as well. Revenues from 
installed assets on a £-per-MW basis have trended up over the 
first quarter of 2024, with LSE-listed Gresham House Energy 
Storage Fund reporting portfolio revenue of £77,900 per MW per 
year in April 2024 as compared with £43,800 per MW per year 
as recently as January 2024. While monthly variation can be 
expected, as more variable resources come online, we expect 
the overcapacity in the UK battery market to be absorbed and 
asset values return to an investable level.

Finally, on the regulatory front, 2024 so far has seen two 
exciting developments. In January, DESNZ released the 
first working paper on a proposed “Cap and Floor” scheme 
to accelerate the deployment of non-lithium, long duration 
storage on the UK grid. This scheme, on whose development 
the Department did and continues to seek Invinity’s input, is 
designed to ensure investable returns for operators of large-
scale LDES projects and inform the development of future 
markets for LDES services. 

Then in March, the House of Lords’ Science and Technology 
Committee released a paper titled “Long-duration energy 
storage: get on with it”, presenting a compelling vision for how 
batteries like Invinity’s can both advance the path to net zero 
while decreasing consumers’ electricity costs. We expect 
strongly positive policies and regulation will flow from this work.

INTRODUCTION

With DESNZ projecting that deploying up to 20 GW of LDES 
can save UK electricity ratepayers up to £24bn, there is ample 
reason to expect success. An election year always injects some 
uncertainty, but with both the current government’s “Powering 
up Britain” and the Labour party’s “Great British Energy” 
platforms firmly supporting long duration storage, we feel 
confident of our prospects.

The U.S.: Focused on Deployment
Where the UK has focused on market innovation to 
accelerate storage, the U.S. focus has been on individual 
technologies and the companies that build them. In March 
2023 the U.S. Department of Energy (“DOE”) published its 
“Pathways to Liftoff” paper presenting how various forms 
of energy storage can enhance integration of renewables. 
That paper was strongly supportive of storage that delivers 
inter-day shifting of renewable energy, the segment where 
Invinity focuses. In June 2023, the Invinity team presented 
a whitepaper based on the U.S. DOE’s analysis at the 
International Flow Battery Forum which identified the inter-
day LDES segment as the one that would deliver the largest 
amount of energy to the grid by 2040.

Based on that work, the DOE has set out to allocate up to 
$3.5 billion worth of funds to LDES projects. Results of the 
highly competitive first round of solicitations were announced 
in September 2023 with only 12 projects being funded, and 
Invinity being the only company to have been awarded funds 
twice. Upon delivery, our 12 MWh project at the DOE’s Pacific 
Northwest National Labs’ Grid Storage Launchpad, and our 72 
MWh of VFBs installed at five sites with the National Renewables 
Cooperative Organization, will be a massive leap forward in 
proving not just the deployability of our batteries at scale, but the 
impact they can have for the grid at large.

From Our Shores to Their Shores
The one undeniable trend all over the world has been towards 
the regional manufacturing of infrastructure equipment in 
general, components for a net zero grid in particular, and battery, 
solar and wind components specifically. 

We initially observed this trend in Asia where grid operators are 
increasingly nervous about security risks posed by products 
made in China. The trend accelerated with the introduction of 
the U.S. Inflation Reduction Act, which provides incentives for 
domestic battery manufacturing. While not every jurisdiction 
has the market power to shift an entire industry, in every country 
where we operate we consistently hear the fastest path to 
adoption is one that aligns with good, well-paying jobs and a 
strong domestic industry. 

Fortunately, Invinity has a tremendous advantage in this 
respect. Our supply chain already has global reach and does 
not rely on “gigafactory” scale production or highly specialised 
manufacturing. As we are proving with our new facility in 
Motherwell in Scotland that, upon completion, will take our UK 
capacity to over 500 MWh per year for customers in the UK 
and EU, we can expand manufacturing based on customer 
demand at a very low capital cost. As we expand our partnership 
strategy to deliver our products globally through capable regional 
partners, we will be able to further scale our business faster than 
either lithium incumbents or new entrants to our industry.

Delivering on Capability
Invinity’s plan to deliver the capabilities that will serve these 
massive and growing opportunities can be summed up in one 
word: Mistral. Mistral is, at its most fundamental, our platform for 
scale. The north star for our business is to build a battery that 
can deliver low-cost, low carbon renewable power on demand 
at a lower total cost of energy than any other source. With 
commercial rollout imminent, both we and our regional partners 
are getting ever more inbound sales inquiries, significantly 
enhancing our commercial pipeline.

Jonathan Wilkinson, Canada’s Minister of Energy and Natural 
Resources, launches Canada’s National Clean Energy Strategy from 
Invinity’s Vancouver facility – August 2023

Our business is highly regional. Mistral is designed for a global 
supply chain both inbound to Invinity and outbound to our 
regional partners, who will deliver the market-specific operating 
knowledge, regional installation capabilities and domestic 
sources of supply that are critical to success. However, we must 
also achieve ultra-low cost, protect our intellectual property and 
ensure consistently high product quality all while accelerating 
speed to market.

In support of those plans, we have been encouraged by our 
current and prospective partners’ response to the “license and 
royalty” model with which we intend to grow our international 
business. In this model, Invinity will deliver core technology 
components to our regional manufacturing partners, who will 
assemble and deliver products to their own regional client base. 
This will allow us to rapidly scale while remaining a capital-light 
business. Our first partner to adopt this model, Everdura in 
Taiwan, has begun work on their final assembly plant, and is 
painting a path for steadily evolving relationships in Australia, 
Eastern Europe and the Middle East.

Conclusion
The coming years for Invinity are all about scale. We need our 
products to be at a scale so they can solve grid operators’ and 
project developers’ most pressing challenges. We need our book 
of business to scale to where we can set the direction of a rapidly 
evolving global market and regulatory landscape. And we need 
our organisation to scale so we can deliver the revenue and 
profits that will see us continually enhance shareholder value.

The foundations for scale – both the opportunity we seek to 
serve and the capabilities we’ll deliver to do so – are clear. 
The need for durable, safe, long duration storage as a critical 
component of a high renewables net zero grid is no longer in 
question and plans to deliver on that need are being developed 
by the world’s most influential agencies, governments and 
regulators. With Mistral, Invinity will have the tool to deliver our 
vanadium flow batteries’ capabilities to the global market. This 
foundation is an incredible starting point, and I’m looking forward 
to delivering its potential alongside the Invinity team.

Chairman’s Report
Delivering progress

I’m pleased to report that Invinity continues to make further 
progress	on	its	Pathway	to	Profitability	Strategy	that	was	
set out on pages 12-13 of our 2022 Annual Report. Our 
achievements in 2023 were focused on our key themes of 
delivery and scaling our business. 

I am especially pleased to note that Invinity has secured 
significant orders for its vanadium flow batteries and grown its 
pipeline of confirmed commercial interest. Growing commercial 
traction underpins our current ramp-up and investment phase 
aimed at delivering a profitable, self-sustaining business. Our 
achievements in 2023 were delivered against a backdrop 
of rapidly growing global renewable energy production and 
storage. Long duration energy storage is a key enabler in 
delivering these plans and governments are being increasingly 
urged to “get on with it” as a means to unlock lower cost, lower 
carbon energy on demand. The launch of our next-generation 
product later this year will further open up this potentially huge 
addressable global market. 

ENGIE Belgium, Equans BeLux, Jan De Nul and the Belgian Energy 
Minister launch their Invinity VFB system – March 2024

Last year I stated that delivery is an important target for the 
Company and I am pleased to report that in 2023 Invinity 
delivered and commissioned more vanadium flow batteries 
in 12 months than ever before. This proven ability to deliver 
cements Invinity’s position as a world leading manufacturer 
of vanadium flow batteries that is meeting the needs of its 
customers. I have been to two site openings in the last 12 
months. One a large Canadian classic solar/storage site and 
secondly a European “behind-the-meter” project delivered by 
ENGIE Belgium, Equans BeLux and Jan De Nul with support 
from the Belgium Energy Ministry. These projects highlight the 
flexibility of our technology and its ability to generate value for 
our customers in a broad range of applications.

Neil O’Brien
Non-Executive Chairman

During 2023 we brought in our customer Everdura as a new 
strategic partner, enabling Invinity to gain operational and 
commercial access into a new market. Strategic partnerships 
are going to be of great importance to Invinity’s long term growth 
and I am pleased to note that our partnership with Everdura took 
a step further early in 2024 when they signed up to become an 
exclusive manufacturer of our next-generation product for the 
Taiwanese market. The partnership route will enable Invinity’s 
leading energy storage products to be deployed in more markets, 
quicker and more economically. 

I am also pleased to note more recently the strategic investment 
secured from the UK Infrastructure Bank (“UKIB”) and Korea 
Investment Partners, who participated in an oversubscribed 
fundraise alongside existing and new investors in May 2024. 
Their backing not only gives a valuable endorsement of Invinity 
and its technology but provides important growth capital which 
will further accelerate our progress towards profitability.

These successes are a testament to the foundations Invinity 
has laid over the last 18 months and I would like to take this 
opportunity to thank the entire team for their hard work and 
perseverance that made this possible. I would also like to thank 
all my Board colleagues for their support and assistance over 
the year, particularly Jonathan Marren who has taken on the 
role of Chief Financial Officer in addition to his role as Chief 
Development Officer. The years of experience, responsibility 
and focus that our Board collectively brings to bear will ensure 
that the Company continues to make the right decisions for its 
long-term future.

Invinity is making progress, having delivered more batteries than 
ever before and secured funding and contracts for almost 100 
MWh of our next generation product. I wish to express the thanks 
of the entire Board for the support we received for our recent 
oversubscribed fundraise. Invinity is now adequately capitalised 
to address the opportunity at hand. We can attract and retain 
quality staff, expand manufacturing capacity and deliver our next-
generation product to our clients. I look forward to this new phase 
in our development.

I have confidence in our team’s ability to deliver on our publicly 
stated strategy. The opportunity is huge and there is much to 
be done.

Getting on with it

Larry Zulch
Chief Executive Officer

I’ve taken inspiration for my report title from Baroness 
Brown who simply titled her recent report to the House  
of Lords “Long-duration energy storage: get on with it”;  
I feel it succinctly captures our challenge. The need is 
acute and progress is required.

Every step toward renewable energy from wind, solar, or 
the tides is simultaneously a call for more energy storage to 
reduce instability. While the most widespread use of energy 
storage—stabilising the grid over seconds or minutes—
remains important, grid stability over the course of a day, 
the “long-duration” referred to in the title, is increasingly 
vital. Invinity’s products can do both.

Scaling up manufacturing and improving our supply chain was a 
major focus in 2023. A new manufacturing facility in Vancouver 
added 200,000 kilowatt-hours of yearly capacity. I am pleased that 
we have recently expanded our capacity in the UK and plan to 
do the same in the U.S. as well in due course. Our supply chain 
improvements reduced costs while keeping environmental, social 
and governance obligations front of mind.

Invinity is progressing well. In 2023, we:

   Delivered more product than ever before;
   Recognised five times more revenue than in 2022;

 Closed significant new deals across each of our core 
markets;
 Secured funding for major projects using Mistral,  
our next-generation product; and 
 Progressed our strategic aim to deliver projects at positive 
gross margin, an important step towards net cash generation.

I am incredibly proud of our team for these accomplishments. 
We are receiving recognition for them: Bloomberg New Energy 
Finance included Invinity on its list of Global Tier 1 battery 
manufacturers for the first time, the only flow battery company and 
the only UK company they recognised.

But our 2023 accomplishments only serve to heighten our 
determination to rapidly and efficiently advance our products, 
their commercial recognition, and our ability to deliver ever-larger 
orders. Before looking forward, however, we should review our 
commitments from 2022.

Our 2023 Achievements
In my 2022 report, I outlined a four-part strategy that would  
enable Invinity to make demonstrable progress year-on-year.  
I am pleased to report significant progress in each area:

1) Deliver on Backlog
Invinity delivered more than 32,000 kilowatt-hours of our vanadium 
flow batteries (“VFBs”) to customers across four continents.

8

2) Close New Deals
2023 saw Invinity sign deals with eight new customers and 
enter into a number of commercial partnerships. We targeted 
and subsequently won a number of funding opportunities that 
will support progressing large high-profile projects toward 
financial close. 

Our sales pipeline, with continued application of strict criteria, 
has grown 170% year-on-year to over 6,000 megawatt-hours 
of qualified commercial demand, giving us confidence that the 
market opportunity remains very real and very large.

3) Deliver Mistral
Mistral, the code name for our next-generation product currently 
being co-developed with Gamesa Electric and Siemens Gamesa 
Renewable Energy, promises to be more capable, more scalable, 
and more economical than other energy storage. That means 
it must operate continuously for decades without degradation, 
function at gigawatt-hour scale, and do so with a low lifetime 
cost per unit of energy stored and no risk of an expensive fire. 
Our current VS3 product has proven these goals are eminently 
achievable, and Mistral will deliver them.

Developing an ambitious new product is not easy, but I am 
pleased to report that the team made significant progress in 2023, 
achieving a fully operational prototype that validated Mistral’s 
fundamental performance targets and operating parameters. This 
major step gave us confidence to initiate pilot manufacturing in 
readiness for Mistral’s official launch later this year.

Performance verification enabled us to begin commercial activity 
for Mistral in 2023 and I am pleased that we met our target of 
securing a Mistral pilot project in the first half of 2023 and a 
commercial order for Mistral later in the year. Additional validation 
came from the U.S. Department of Energy (“DOE”) which 
awarded funding for 84,000 kilowatt-hours of Mistral projects 
after an extensive process evaluating Mistral and Invinity’s 
capability to deliver it.

4) Operational Excellence
Outward progress must be matched by internal capabilities, and 
in 2023 we focused on efficient delivery of more product than 
ever before and the processes that enable us to continue to grow. 
The delivery and commissioning of more than 28,000 kilowatt-
hours of our VS3 product demonstrates success.

We focus on making Invinity a great place to work; the best 
workforce allows us to produce the best VFBs.

Looking Forward
In our recent fundraise, we highlighted our strategy of utilising 
partnerships. In the U.S. and UK, our partners help us pursue 
capex-light manufacturing and direct sales. Outside these core 
markets, we are working with existing and pursuing new partners 
capable of commercial engagement, product and project 
support, and after-sales activities. Our relationship with rest-of-
world partners typically starts with reselling our products but can 
lead to manufacturing under a licence and royalty model.

the agreement for Everdura to set up domestic manufacturing in Taiwan 
– September 2023

1) The UK Market
Each year, the UK discards (“curtails”) enough renewable 
energy to power an estimated million homes. Much of this could 
be captured in LDES and used effectively. However, current 
regulatory support for energy storage focuses on grid stability 
and therefore shorter-duration batteries. We know LDES projects 
to be economically compelling but proving that requires financial 
returns from operating LDES projects. The UK Government is 
helping us provide that proof: 

 In April 2023, Invinity secured £11 million of matched funding 
under Phase 2 of the UK Government’s Longer Duration 
Energy Storage (“LODES”) Competition for the largest VFB 
deployed in the UK.
 The House of Lords released the aforementioned report from 
the Science and Technology Committee on LDES and its 
critical role in UK electricity supply.
 More recently, the UK Infrastructure Bank, wholly owned and 
backed by HM Treasury but operating independently, made a 
£25 million equity investment in Invinity to support UK LDES 
projects, manufacturing and jobs. 

The UK electricity market has great potential for Invinity given the 
significant need for LDES and the UK Government’s support for 
its deployment. Our manufacturing and electrochemical research 
in Scotland supports our focus on the UK. We envision an LDES 
growth phase occurring in the UK just as Mistral becomes 
available to dramatically expand our capabilities.

2) The North American Market
A somewhat different approach is required to address the 
enormous LDES market in North America, though in both 
markets, adoption of renewable energy is limited by the 
deployment of energy storage. Governments are stepping in to 
accelerate LDES projects with one prominent example being the 
U.S. Inflation Reduction Act of 2022 which provides tax credits 
that support energy storage projects. Further examples include:

  In June 2023, The British Columbia Centre for Innovation 
and Clean Energy provided funding to support the very first 
Mistral project;
 In September 2023, the U.S. DOE awarded funding 
for a 12,000 kilowatt-hour Mistral project at the Pacific 
Northwest National Laboratory (“PNNL”), an energy 
research lab with more than 6,000 scientists, engineers, 
and professional staff. This will be the largest battery 
system ever provided to PNNL; and 
 The September 2023 U.S. DOE announcement also 
announced funding for 72,000 kilowatt-hours of Mistral to 
be installed at five regional energy cooperatives.

Qualifying for government support in the U.S. requires 
meeting certain requirements for U.S. domestic content. 
Invinity has developed relationships with various partners to 
support a capex-light strategy to optimize our supply chain 
and U.S. manufacturing.

We see the North American market as having very high potential 
for Invinity. There is an emerging need for non-lithium LDES, and 
Invinity is in a prime position to address that need with Mistral.

3) Outside Core Markets
Invinity cannot address the worldwide need for LDES with a local 
presence in every area with potential. The solution is to identify 
partners able to fully represent our products.

An example is our relationship with Everdura in Taiwan. Everdura, 
whose parent Everbrite made an equity investment in 2023 in 
Invinity, has been pursuing commercial opportunities for Invinity’s 
products across the entire ASEAN region. In September 2023, 
Everdura became our first commercial customer to place a 
Mistral order.

In February 2024, Everdura signed a manufacturing agreement 
for Mistral that gives Invinity a royalty based on a percentage of 
their Mistral revenue in exchange for direct access to our supply 
chain and the ability to order our proprietary cell stacks and 
software directly from Invinity. 

We are pursuing other similar high-potential relationships and 
look forward to announcing them in due course.

Conclusion
Mistral is a differentiated product with compelling economics. 
It promises to operate continuously for decades with high 
throughput, no degradation, and zero chance of a fire (our water-
based electrolyte is entirely non-flammable). Bringing Mistral to 
market is our highest priority and I’m pleased to say it is going 
well, though certainly there are challenges, many we’ve met and 
some still to come. However, we view every challenge as an 
opportunity to prove our capabilities and take us further ahead of 
the competition.

Mistral in itself is not enough. We must have an appropriate 
strategy, tailored by region, for commercialization and 
manufacturing; embrace and enhance our relationships with 
partners; operate efficiently and effectively; and reduce the potential 
impact of events outside of our control. And, finally, we must rapidly 
become profitable, the ultimate measure of our success.

We are doing all of this with the finest team I have ever had the 
privilege of leading and the continued support of our investors 
and our partners. I am endlessly grateful for both.

Net Finance costs were £0.4 million (2022: £0.4 million income) 
with the majority of the difference being the costs associated with 
the repayment and termination of the convertible loan instrument 
that was entered into on 14 December 2022 to provide additional 
working capital for the business and was completed in the year.

Total inventory and pre-paid inventory reduced to £4.4 million 
(2022: £14.9 million) as a result of the conversion into revenue 
from the delivery of products during the year and in particular 
the Spencer Energy, Viejas Casino & Resort and Elemental 
Energy projects. Considering wider balance sheet items directly 
relating to product sales (i.e. Trade receivables, Accrued income, 
Deferred revenue, Trade payables, Provision for contract 
losses and Warranty provision), the net balance sheet position 
increased by £0.4 million to £3.6 million (2022: £3.2 million). 

2023 Financial Performance
I am pleased to report that total income including sales revenue 
and project related grant income increased significantly 
to £22.0 million in 2023 (2022: £3.6 million). Revenue is 
recognised against projects when specific performance 
obligations related to those projects have been satisfied. 

In the year, revenue was recognised on 15 projects across 
Australia, the U.S., Canada, the UK and Europe totalling over 
35 MWh of projects. This marks the first time the Company has 
recorded significant revenue and represents a major milestone. 

As in the prior year, grant funding specific to customer projects 
has been presented alongside the relevant project revenue and 
associated direct costs where that funding is project specific and 
represents a direct subsidy against project costs. Unlike 2022, 
such grant funding only constituted a negligible part of total 
revenue and grant income other than revenue.

The Company recorded a gross loss of £3.3 million (2022: 
gross profit of £0.7 million) but it is notable that the gross profit 
recorded in 2022 included the writing back of £3.2 million  
of provisions.

The Company has a strategic aim to move to delivering projects 
at positive gross margins and this positive trend continues with 
the majority of the gross loss being attributed to projects signed 
before 2022 and with the more recent projects being at broadly 
flat or small positive gross margins at the project level (before 
allocation of facility costs).

Administrative expenses did not change significantly from the 
prior year at £19.1 million (2022: £19.0 million) reflecting a 
continued focus on managing costs. Administrative costs were 
represented by an increased investment in people with staff costs 
of £12.8 million in 2023 (2022: £10.3 million) and professional 
fees decreased to £0.7 million in 2023 (2022: £3.0 million), 
benefiting from the one-off items in 2022 not recurring in the 
current year. Sales and marketing costs increased to £1.0 million 
(2022: £0.2 million) as a result of continuing investment in this 
area to support marketing the Company’s products, depreciation 
of £1.1 million (2022: £1.2 million) and IT costs of £0.9 million 
(2022 £1.2 million). Net research and development recoveries 
were £0.1 million (2022: £1.6 million costs) reflecting recoveries 
from Gamesa Electric S.A.U. (“Gamesa Electric”) under the 
Joint Development and Commercialisation Agreement (“JDCA”) 
whereby Gamesa Electric agreed to fund up to an aggregate 
US$4.62 million of Invinity’s activities towards the development of 
the Company’s next-generation product, code-named “Mistral”, 
payable as development milestones are met.

In addition, as part of the capital raise in March 2023, 
Everbrite Technology Co. Ltd. (Everbrite), a leading 
Taiwanese manufacturer of industrial technology, subscribed 
for £2.5 million of shares in the Company. The investment by 
Everbrite followed the 1 December 2022 reseller agreement 
and initial 15 MWh purchase order of vanadium flow batteries 
with Everdura Technology Company, a joint venture between 
Everbrite and Taiwanese clean energy company, Pronergy 
Technology Co. Ltd, covering Taiwan and Southeast Asia. 

These strategic investments underscore the development 
progress of the Company since the 2020 merger transaction 
that formed the Group as it is today and, in relation to the 
agreement with Everbrite, is intended to support a closer 
strategic relationship for the deployment of vanadium flow 
batteries in Taiwan and further afield. 

Going Concern
Following completion of the fundraising in May 2024, the 
Company had cash of £53.2 million as at 31 May 2024  
(2023: £15.4 million).

The Directors have prepared a cash flow forecast for the 
period from the balance sheet date until 30 June 2025. This 
forecast indicates that the Group would expect to remain 
cash positive during this period and without the requirement 
for further fundraising. The business continues to be in a 
cash outflow position, using funding generated from previous 
fundraises (although it is planning to move to a cash inflow 
position upon the launch and delivery of material volume of 
Mistral). As such, this cash flow forecast was stress-tested 
for a worst-case scenario of no positive cash receipts from 
sales. In this tested scenario, the business would remain 
cash positive for the 12 months from the date of approval of 
these financial statements. The accounts have therefore been 
prepared on a going concern basis.

Jonathan Marren
Chief Financial Officer and Chief Development Officer
26 June 2024

2023 Cash Performance
Year-on-year cash outflow from operations reduced to 
£19.7 million (2022: £21.9 million) principally as a result of a 
net improvement in operating assets and liabilities as set out 
in note 14. 

As stated above, the Company has a strategic aim to move to 
delivering projects at positive gross margin and this positive 
trend continues with the more recent projects being at broadly 
flat or small positive gross margins at the project level (before 
allocation of facility costs). Delivering on this margin is a key 
corporate priority and will make an important contribution to the 
Company being able to fund its administrative costs from cash 
from operations in the future.

To this end, the Company continues to develop Mistral. Mistral 
is expected to be manufactured at significantly lower cost than 
the Company’s existing product, the VS3 and, when deployed, 
will occupy a comparatively smaller physical footprint that will 
lead to lower costs for operations and maintenance. These 
characteristics are expected to enable the Company to sell this 
new product at a materially lower and more competitive price 
point than currently. This is anticipated to drive additional sales 
at a materially better gross margin thus leading to future cash 
generation and profitability.

Funding and Net Working Capital 
At 31 December 2023 the Company had cash and cash 
equivalents of £5.0 million (2022: £5.1 million). The Company’s 
cash balance during 2024 has been materially increased 
following the successful conclusion of a capital raising of 
£57.4 million which completed in May 2024.

At the prior year end, the Company had recorded a 
US$2.5 million convertible loan instrument taken out with 
Riverfort Global Opportunities PCC Ltd and YA II PN that 
was entered into on 14 December 2022 to provide additional 
working capital for the business. This convertible was entirely 
repaid during the period.

Accordingly, the Company was debt free as at 31 December 
2023 and remains so as at the date of this document.

Strategic Investment 
As noted last year, Invinity sees strategic partnerships and 
investment as an important pillar of its future corporate 
growth and it was delighted to conclude a material strategic 
investment from the UK Infrastructure Bank of £25.0 million 
and an investment from Korea Investment Partners of 
£3.0 million as part of a larger £57.4 million fundraising 
completed in May 2024.

and general alignment with national 
energy policy and regulation.

Whilst sales contracts are bilateral, 
they are usually part of multi-party 
projects.

Whilst Invinity contracts directly with 
the project developer, that same 
developer is contracting with a 
number of other parties as part of 
financial close, which may therefore 
be delayed for reasons unrelated to 
the Invinity contract.

Most near-to-medium term sales 
are expected to require an element

the local, regional or national 
governments.

A bankability study was completed 
during 2022 which should enable 
Invinity to ensure that the correct 
criteria are met as early as possible.

Commercialisation of the 
Company’s technology is still in 
process and therefore product 
may fall short of performance 
expectations.

With the first VS3 contracts

Sustainability Report
How Invinity is Supporting  
a Just and Equitable Transition

The impacts of Climate Change continue to be evidenced 
worldwide. Providing a solution to address this forms the 
fundamental tenet of our business and Invinity remains 
even more committed to our role as part of the solution to 
the global climate emergency. 

As chair of Invinity’s Environmental, Social and Governance 
(ESG) Committee which regularly presents the Company’s 
ESG progress to the Board, I am pleased to provide this report 
which focuses on Invinity’s environmental and societal progress 
throughout 2023. Invinity’s Board of Directors also believes that 
strong corporate governance and effective risk management 
are key to the delivery of shareholder value, and the Board has 
adopted the Quoted Companies Alliance Corporate Governance 
Code. Further details on this are covered in the Governance 
section of this Annual Report. 

A Just and Equitable Transition
Invinity believes that there is no contradiction between 
sustainable development, a healthy economy, and a clean 
and safe environment. The principal of operating sustainably 
sits at the heart of the Company’s business and is important 
to our future. 

It is widely acknowledged that the transition of energy away 
from fossil fuels will bring significant environmental benefits to 
communities around the world. The rapid deployment of energy 
storage alongside clean renewable generation, such as solar and 
wind, provides a secure route to lowering emissions by allowing 
clean energy to be dispatched 24/7.

However, this transition also has the potential to bring about 
significant social change as economies must adapt. Invinity 
believes it is important that no one is left behind as part of this 
transition. We recognise the significance of this change and it 
is why the Company is pleased to be undertaking a series of 
endeavours designed to make a positive societal contribution  
for the benefit of all stakeholders.

Invinity is proud that its safe, durable and reliable energy storage 
solution, and the manner in which we operate, has the ability to 
accelerate the Just and Equitable transition to net zero.

Environment
Credentials 
Invinity takes great pride in being recognised as a leader in 
clean energy. The Company was one of the first to be awarded 
the London Stock Exchange’s Green Economy Mark back in 
2019 and we are gratified to continue to maintain our status as 
a company that derives more than 50% of its revenues from 
products and services that are actively contributing to climate 
change mitigation and adaptation, pollution reduction and the 
circular economy.

The Company has been a signatory on the SME Climate 
Commitment since 2021, recognising that we cannot expect 
others to reduce their carbon footprint if we do not do so 
ourselves. Invinity continues to monitor, and is working to reduce, 
its carbon footprint across its operations and employs a quality 
audit to ensure its supply chain is in line with the Company’s 
long-term social, environmental and economic values that aim to 
generate further benefits.

Invinity continues to recognise that the Just Transition provides 
impetus for everyone towards meeting the United Nations 
Sustainable Development Goals. The Company is pleased 
with its ongoing contributions to, amongst other goals, Goal 7: 
‘Affordable and Clean Energy’, Goal 11: ‘Sustainable Cities and 
Communities’, and Goal 13: ‘Climate Action’.

Circular Economy
A major requirement of the Just Transition is that companies 
help build a more circular economy, one that reduces waste and 
creates further value for all. Invinity’s vanadium flow batteries are 
well-suited to support the transition because: 

 they are recyclable: almost 100% of an Invinity VFB can be 
fully recycled, ensuring virtually no waste is created at end-
of-life; 
 their lack of degradation means that nearly 100% of the 
vanadium itself will also be recovered for further use in other 
applications; and 
 our batteries do not contain any ‘conflict’ materials, such as 
cobalt, ensuring we have a socially sustainable product.

Invinity is proud of its efforts to date that are helping to further 
protect the environment, reduce our use of virgin raw materials 
and help to improve quality of life for all.

18

Invinity Energy Systems plc Annual Report and Financial Statements 2023  
  
  
Invinity is committed to further improve the sustainability of its 
products for the long term. The recognition of the sustainable 
role that our vanadium flow batteries play (see case studies 
below), and the knowledge that they will leave almost no 
waste behind at end-of-life, provides confidence to go further 
in our pursuit of an even more sustainable solution for the 
energy transition.

Carbon Footprint Reporting
Invinity is a fast-growing company that remains committed to 
taking action to reduce its own carbon footprint. The Company 
has a range of policies in place, which are reviewed and 
adopted annually at Board level, to ensure that our impact is 
minimised as we grow.

2023 Group Carbon Intensity:

8.96g CO2e 

per £1 of recognised revenue

91% reduction 

in carbon intensity vs 2020  
(base year chosen as year of Invinity’s formation)

INVINITY CARBON FOOTPRINT 2020-23

Invinity reports its carbon footprint in compliance with the 
world’s most widely used greenhouse gas reporting framework, 
The Greenhouse Gas Protocol, and with the SME Climate 
Commitment. The Company reports on its direct emissions  
(Scope 1) and indirect emissions (Scope 2) and uses an 
operational control accounting approach which involves 
accounting for all emissions from operations over which the 
Company has control. Finally, as per SME Climate Commitment 
guidelines, as a “fast growing SME that provides solutions which 
avoid or remove emissions as their core business”, it is considered 
appropriate for Invinity to report its carbon footprint on an ‘intensity’ 
basis, using the metric of grammes of CO2 equivalent per £ of 
annual revenue.

Invinity is delighted to report that it has continued to reduce its 
Carbon Intensity and minimise the greenhouse gas emissions of 
its activities year on year. 

Social
As part of our strategy to maintain and improve Operational 
Excellence, Invinity encourages socially responsible 
practices within its global operations and is embedding them 
to help the Company on its pathway to profitability. Being a 
socially responsible business is an important part of the Just 
Transition and is of critical importance to Invinity as it will 
ensure the Company’s future operations continue to bring 
benefits to all stakeholders.

as they started it. This commitment is reflected throughout the workforce who are empowered to speak out on safety to ensure Invinity 
maintains the highest possible standards in this regard.

CASE STUDIES

Two of Invinity’s signature VFB projects, our 5 MWh VFB at the Energy Superhub Oxford and 
our 8.4 MWh VFB at Elemental Energy’s Chappice Lake Solar & Storage site, are helping their 
respective local grids to reduce their carbon emissions by dispatching clean energy on demand:

    In July 2023, Energy Superhub Oxford published data for its 

    In September 2023, the Chappice Lake Solar & Storage project 

first year of operation, noting particularly that it saved c.732.66 
tonnes of carbon (the equivalent of planting 4,300 trees) and had 
provided over 1.1 GWh of power to local residents. This battery, 
combined with the EV charging hub, low carbon heating network 
and smart energy management technologies together will help to 
eliminate 10,000 tonnes of CO2 per year, rising to 25,000 tonnes 
per year by 2032.

became operational and began supplying clean energy to the local 
Albertan Grid, enough to power around 3,000 homes. This project, 
which is also backed by the Cold Lake First Nation, is expected 
to achieve annual carbon savings of c.20,000 tonnes of CO2e. 
The Company is proud of its commitment to work with indigenous 
nations, particularly through its partnership with Indian Energy which 
covers North America, and the Chappice Lake project shows how 
government, industry and indigenous nations can work together to 
ensure everyone can benefit from the just transition.

Diversity
Invinity is committed to fostering a diverse, inclusive and 
equitable workplace. Workforce diversity has been proven to 
boost creativity and innovation, provide greater opportunities for 
professional growth and leads to better decision-making. The 
Company monitors the age distribution across its employees to 
ensure it is well-placed for the future and that its hiring policies 
are appropriately managed. Invinity is a keen supporter of 
Women in STEM roles and is proud to note that the Company 
hired its largest number of female staff in 2023, including into 
the engineering functions within the business. The Company 
also began measuring ethnic diversity within the Group in 2023 
to better identify and prevent bias as part of its Operational 
Excellence strategy. Invinity continually reviews its activities across 
each of these areas to ensure the Company is doing the right thing 
and that all Invinity stakeholders can benefit.

Initiatives and Programmes
Social responsibility programmes are recognised important tools 
that can boost employee morale, lead to greater productivity 
and increase customer retention and loyalty. A happy, diverse 
and motivated workforce not only leads to better outcomes for 
all stakeholders but also to increased brand recognition and 
awareness in the industry. Furthermore, these programmes will 
also enhance Invinity’s growing reputation as a company that 
takes its social responsibilities seriously as the world makes a Just 
Transition to net zero.

Invinity has a number of initiatives and programmes in place to 
ensure the Company is doing as much as is possible to enhance 
its social responsibility. Specific programmes include:

   Women in Tech Roundtable

 Set up in 2022, this initiative created an open forum for the 
women at Invinity to discuss a wide range of topics selected by 
female employees as well as a major focus on how to increase 
the number of female staff at Invinity. 

Invinity Leadership Council (ILC)
 The ILC, established in 2023, has a mandate to foster better 
culture, communication and collaboration across the entire 
organisation. The group includes the Company’s Senior 
Leadership Team as well as other senior staff members from 
across all facets of the business. Their purpose is to identify 
organisational challenges and discuss potential solutions 
through presentations and Q&A. Within the ILC, a sub-
committee also specifically focuses on employee engagement 
by gathering feedback and implementing initiatives designed 
to improve employee experience. This feedback is collected 
through open discussion meetings and is presented to the 
Executive Committee.

   Student Engagement

  Invinity continues to offer internships (in the UK) and Co-
ops (in Canada) for students to provide valuable first-hand 
experience in a professional setting and thereby enable 
Invinity to recruit future employees who are interested in 
the green economy. Over the past three years, Invinity 
has employed a significant number of students in both 
the UK and in Canada, many of whom have gone on to 
become full-time employees, with others gaining valuable 
experience that has helped them to start successful 
careers in the clean energy industry. In 2023 Invinity 
increased its student hires by 25% YoY and has plans to 
continue this trend throughout 2024 and beyond.

   Employee-led Social Initiatives

  Invinity is highly supportive of its employees carrying out 
activities that are designed to enhance inter-office links 
and support other social benefits, recognising that good 
employee cohesion is vital to the health and productivity 
of the workforce. Specific employee-led examples 
include charitable fundraising events held at Invinity’s 
Bathgate office and a global fitness event connecting 
UK, Canadian, American and Australian-based staff 
across the whole Company. Employees at all levels of the 
Company participated in these events and Invinity actively 
encourages and supports its staff as they look to undertake 
similar activities.

These initiatives are enabling Invinity not only to play an active 
role in the local community by sharing our knowledge and 
providing new opportunities for those in the local area, but also 
fostering inclusive and open attitudes and healthy activities 
amongst our staff.

Invinity’s commitment to sustainability for the environment and 
society, as well as the principles of the Just Transition, is a 
non-negotiable part of Invinity’s development. Furthermore, the 
Company is proud of the successes it has achieved and the 
enhanced initiatives it has deployed in 2023 in support of our 
hard-working team to make Invinity a great place to work. We 
fundamentally believe that good practices embedded now will 
ensure that Invinity is well set for the future.

committed to maintaining high standards of corporate governance 
for which the Directors are accountable to shareholders and

regularly reviewed as the Company grows to ensure that they 
remain appropriate and effective.

Board Composition
The Board currently consists of a Non-Executive Chairman, three 
Executive Directors, a Senior Independent Director and two other 
Non-Executive Directors.  

Board Meetings and Processes
The Board has around eight scheduled meetings each year with 
other meetings held as required. Informal meetings also take 
place between the Chairman and the Non-Executive Directors 
without the Executive Directors being present. 

During 2023, Jonathan Marren was confirmed as permanent 
Chief Financial Officer alongside his existing role as Chief 
Development Officer. 

The role of the Senior Independent Director is to provide a 
sounding board for the Chairman and to act as an intermediary 
for Board members and as a point of contact for shareholders 
who have concerns which have not been adequately addressed 
by the Chairman or Chief Executive Officer. 

Other than any shareholdings in the Company and the receipt 
of fees for acting as Directors, the Chairman and Non-Executive 
Directors have no financial interests in the Company or business 
relationships that would interfere with their independent judgement. 

Independence of Directors 
The Board considers that the Chairman and all the Non-
Executive Directors were independent for the whole of the 
2023 financial year notwithstanding circumstances which could 
indicate otherwise specifically the length of tenure of Michael 
Farrow and Neil O’Brien’s previous role as Executive Chairman. 
While recognising that Michael Farrow has been a Director for 
18 years, the practicalities of maintaining corporate residency in 
Jersey means that it is advantageous to have a knowledgeable 
and actively participative director located there. The Board 
has determined that both these individuals demonstrate 
independence of character and judgement and that there are no 
circumstances which are likely, or could be perceived to be likely, 
to affect their judgement. The Board also note their intention to 
redomicile the Company to the UK and expect this activity to 
include a restructuring of the board composition.

Role of the Board
The Board is collectively responsible for delivery of the strategy 
which is designed to promote the long-term success of the 
Company and to deliver shareholder value. The Board is 
responsible for formulation and approval of the Company’s 
long-term objectives and strategy, ensuring an appropriate 
organisational structure and knowledge to cater for changing 
external and internal environments. This would include approval of 
budgets, oversight of operations across the Group, maintenance 
of internal controls and risk management systems and approval of 
Group policies. The Board may delegate specific responsibilities 
but there is a schedule of matters specifically reserved for decision 
by the Board to ensure that it exercises control over the key 
matters which could impact on delivery of the Company’s strategy.  

Board Skills and Responsibilities 
The Directors have a wide range of skills and industry experience 
including technical, operational, commercial and financial both in the 
UK and internationally. The Chairman and Non-Executive Directors 
have held senior management, Board and advisory positions and 
bring relevant experience from their current and previous roles. 

A clearly defined organisational structure exists across the 
Group, with lines of responsibility and delegation of authority 
to executive management. 

At each Board meeting, the Board receives an update from the 
CEO on key current activities, including HSE, and considers the 
Commercial and Finance Reports and any papers relating to 
specific matters requiring consideration or approval. 

Non-Executive Directors affirm on joining the Company that they 
are able to allocate sufficient time to discharge effectively their 
responsibilities and are required to keep the Board updated of any 
changes in respect of their other commitments.

The letters of appointment of the Non-Executive Directors 
detail the expected time commitment which is around six Board 
meetings, one General Meeting and two meetings in respect 
of each of the Board Committees per annum and are required 
to devote to the Company’s business such additional time as 
is reasonably necessary by way of preparation for, or follow-up 
after, any meeting. The Non-Executive Directors may also be 
asked to participate in other events such as marketing, social and 
client functions with this commitment not exceeding around six 
days per annum.

In addition to the scheduled Board meetings shown above, 
a number of meetings were held to deal with administrative 
matters including exercises of warrants and grants and exercises 
of share options and approval of documentation required for 
grant funding applications. 

The  Board  has  also  established  a  Standing  Committee  of  the 
Board to deal with ad hoc matters arising between Board meetings. 
The Standing Committee is only used in exceptional circumstances 
where  it  is  not  practical  to  convene  a  full  Board  meeting.  All 
Directors  receive  notice  of  any  meetings  and  the  matters  to  be 
discussed and can attend the meeting or request that the matter 
under consideration be considered at a full Board meeting.

Board Performance Evaluation 
Post the successful fundraising in May 2024, there are a number 
of Board changes expected to occur as Invinity redomiciles to the 
UK and the UK Infrastructure Bank takes up their Board position. 
The Board will evaluate performance and any gaps in knowledge 
and experience that may occur with these changes later in 2024.

Board Induction, Training and Outside Advice
There is no set induction process but new Directors receive 
a briefing on AIM obligations from the Company’s NOMAD, 
Canaccord Genuity, as well as an appropriate induction 
according to their requirements. 

The Board supports Directors who wish to receive ongoing 
training and education relating to their duties. 

Independent legal advice is available to Directors at the 
Group’s expense if external advice is considered necessary 
and appropriate.

External Directorships and Interests 
Executive Directors are permitted to engage in other activities 
and businesses outside the Group providing that there is no 
risk of conflict with their duties or commitments and subject to 
full Board disclosure.

Non-Executive Directors are required to advise the Chairman as 
soon as practicable of any proposed Board appointments which 
could give rise to a conflict with their position as a Director of the 
Company. Details are circulated to other Board members who are 
invited to advise the Chairman if they have any concerns about 
the proposed appointment.

Conflicts	of	Interest	
The Board has in place a procedure for dealing with actual or 
potential conflicts of interest. All Directors are obliged not to put 
themselves into a situation which may give rise to a conflict of 
interest, however, if such circumstances do arise then they are 
required to make full disclosure to the Chairman. If requested by 
the Chairman, a Director will absent themselves from any Board 
discussions and decisions on matters where there is an actual 
or perceived conflict of interest.

Company Secretary 
The Company Secretary is Oak Secretaries (Jersey) Limited 
which is 100% owned by the Oak Group (Jersey) Ltd (Oak 
Group), a Jersey-based limited liability company regulated by 
the Jersey Financial Services Commission. Michael Farrow 
was a director of the Oak Group until his retirement from that 
company in May 2019. The Company has also engaged the 
services of a qualified company secretary to assist with the 
administration of the share option scheme, compliance and 
to provide corporate governance advice and general support 
to the Board and its Committees. 

Communication with Shareholders 
The Company engages with shareholders in a variety of ways:

Meetings
Executive Directors meet regularly with major shareholders 
and the investment community which allows exposure to new 
investors, either online or in person. This process includes 
presentations, one-to-one meetings and both buy and sell-
side analyst briefings. The Chief Executive Officer regularly 
briefs the Board on meetings held and relays the views 
expressed. Details of analyst research reports, press reports, 
share trading and register analyses are shared with Directors 
which ensures that they are kept up to date with the views of 
the investment community. 

Website
The Company’s website is updated regularly and includes 
a dedicated Investor Relations section. This includes all 
direct shareholder communications, external presentations, 
Q&As with Directors and other relevant documentation so 
that existing and potential investors have access to up-to-
date and relevant information.

Investor Relations 
The Company encourages direct contact from shareholders and 
potential investors by providing an email address and telephone 
number for investors on the website which is monitored by 
the Director of Communications & Investor Relations and the 
Corporate Relations Manager. This allows investors to address 
ad hoc queries to the Company.

Announcements 
The Company issues announcements via the Regulatory News 
Service (“RNS”) and press releases periodically to inform the 
market of significant news and developments.

Webinars
The Company hosts regular interactive webinars which give 
shareholders the chance to address questions to management. 

Annual Report 
The Company’s annual report gives a detailed overview of the 
Company, its strategy, operations, financial position, risk profile 
and remuneration structure and is available in hard copy and on 
the website. This ensures that existing and potential investors 
are provided with the information that they need to make an 
assessment of the Company’s performance and prospects.

Political and Charitable Donations 
The Group made no charitable or political donations during the 
year (2022: £nil).

Newsletter
The Company issues regular newsletters for Investors and any 
interested parties who have subscribed to receive updates on the 
Company’s activities beyond what is issued through the RNS. 

AGM
In addition to the formal AGM business, the executive team give 
an operational and financial update and shareholders have the 
opportunity to address questions to the Board.

Role
The core terms of reference of the Audit & Risk Committee include 
reviewing and reporting to the Board on matters relating to: 

  the audit plans of the external auditors; 
 the Group’s overall framework for financial reporting and 
internal controls including monitoring, overseeing and assessing 
the Group’s strategy and framework of policies, procedures, 
systems and controls to identify, assess, manage and report on 
compliance matters;

 the Group’s overall framework for financial reporting and 
internal controls; 
  the Group’s overall framework for risk management, focusing 
on financial risk; 
  the accounting policies and practices of the Group; 
  the annual and interim financial reporting carried out by the 
Group; and
  the independence and performance of the external auditor. 

The Committee is responsible for notifying the Board of any 
significant concerns that the external auditors may have 
arising from their audit work, any matters which may materially 
affect or impair the independence of the external auditors, any 
significant deficiencies or material weaknesses in the design 
or operation of the Group’s internal controls and any serious 
issues of non-compliance. 

No such concerns were identified during the financial period. 

Key Matters Considered by the Committee 
During the year, the issues considered by the Committee both 
during and outside formal Committee meetings included: 

  Group financial disclosures and accounting matters and 
policies relating to the preparation of the financial statements;
  Audit plan of the external auditors for the 2023 financial year;
  Reports of the external auditors concerning its audit and 
review of the financial statements of the Group; 
  2022 Annual Report and Accounts and 2023 interim financial 
statements; 
  External auditors’ fees; and 
  Change of external auditors. 

Going Concern
As part of the year end reporting process, management prepares 
a detailed report including detailed cashflow forecasts with a 
number of potential scenarios and sensitivity assumptions. The 
Committee reviews and challenges management’s assumptions 
and conclusions in order that it can provide comfort to the Board 
that management’s assessment has been challenged and is 
supported and that it is appropriate to prepare the financial 
statements on a going concern basis. Further details of the going 
concern assessment process are contained in Note 2 of the 
Group financial statements.

External Auditors
The Committee recommends to the Board the appointment of 
the external auditors, subject to the approval of the Company’s 
shareholders at a general meeting. Shareholders in a general 
meeting authorise the Board to fix the remuneration of the 
external auditors and the Board has delegated this responsibility 
to the Committee.

The Committee actively considers the effectiveness and 
quality of the external auditors on an ongoing basis and, if 
considered appropriate, will retender for the position of external 
auditor. During the year, the Committee undertook a tender 
process for the Group audit as a result of which the Committee 
recommended to the Board that BDO LLP be appointed as 
external auditors in place of PricewaterhouseCoopers LLP. BDO 
LLP were subsequently appointed as auditors to the Company 
from 30 November 2023. 

The Committee is responsible for the approval of the provision of 
all audit services and permitted non-audit services undertaken 
by the external auditors. Since the year end, the Committee 
has adopted a policy on the independence and objectivity of the 
external auditor which includes a list of permitted and prohibited 
non-audit services.

The Committee is responsible for assessing the effectiveness 
and quality of the external auditors.

The Company is committed to conducting all of its business 
dealings in a responsible, honest and ethical manner. All

I am pleased to present the report of the Nomination Committee 
for the year ended 31 December 2023.

taken to ensure that appointees have enough time to devote to 
the job. 

Succession Planning 
The Company is committed to appointing, retaining and

that the Company needs in order to support delivery of the agreed 
strategic objectives. 

The Committee recognises the need for progressive refreshing 
of the Board and the benefits of diversity and the Committee 
will have regard to these when considering succession 
planning. When considering new Board appointments, the 
Committee will be committed to recruiting on merit measured 
against objective criteria. 

The management of human resources across the Group is 
a matter for the Executive Directors but the Non-Executive

of senior appointments.

Report of Chair of the  
Remuneration Committee

Kristina Peterson
Chair, Remuneration Committee

Introduction by the Remuneration Committee Chair, 
Kristina Peterson 

I am pleased, on behalf of the Remuneration Committee, to 
present the Directors’ Remuneration Report (‘Report’) for the year 
ended 31 December 2023. 

The Report is divided into two sections:

  The Policy report which sets out the current Remuneration 
Policy; and 
  The Annual Report on Remuneration which sets out details of 
the operation of the Remuneration Committee and details of 
the Directors’ remuneration packages for the year ended 31 
December 2023. It also sets out details of the implementation 
of the Remuneration Policy for Executive and Non-Executive 
Directors for the year ending 31 December 2024.

In early 2023, the Remuneration Committee engaged Alvarez 
& Marsal Tax LLP (“A&M”) to review Executive and Non-
Executive Director compensation and provide benchmarks and 
recommendations compared to its AIM-traded peers. A&M’s 
report was used as the basis of the salary and incentives review 
undertaken during the year, details of which are in the Director’s 
Remuneration Report which follows. 

The Committee is satisfied that the outcomes, in respect of the 
incentives and remuneration during the financial year under 
review, are appropriate. The Committee will continue to ensure 
that the Company’s Remuneration Policy and practices are 
kept under review to ensure that they remain appropriate for 
the Company at its stage of development and that they do 
not encourage any unnecessary risk taking by the Executive 
Directors.

We recommend our Report to shareholders although do not 
seek their formal approval. I would be happy to discuss any of the 
above matters with individual shareholders should they so wish.

Directors’ Remuneration Report

REMUNERATION POLICY
This part of the Report sets out the remuneration policy for the Company. The policy for the Executive Directors is determined by 
the Committee and the Committee recommends to the Board any adjustments to salary and bonus awards. The Committee also 
makes recommendations to the Board in respect of the remuneration packages of certain members of the senior team based on 
recommendations from the Chief Executive Officer. Authority is delegated to the Executive Directors to manage the remuneration 
packages of all other employees. Awards of share options to employees under the Company’s Share Option Plan are the responsibility 
of the Board which considers recommendations from the Chief Executive Officer in respect of employees.

The aim of the Committee is to ensure that the remuneration packages are sufficiently competitive to attract, retain and motivate 
individuals of the quality required to contribute towards the strategic objectives of the Group and thereby enhance shareholder value. 
The Committee also aims to ensure that all employees receive rewards that fairly reflect their seniority, level of work and contribution to 
the Company. 

The Company is committed to promoting equal opportunities in employment with all employees and potential employees receiving 
equal treatment. 

EXECUTIVE DIRECTOR POLICY
The summary of the remuneration policy for the Executive Directors is set out below. Full details of the remuneration packages are given in the 
Report on Remuneration.

Salary

Purpose and link to strategy 

To provide an appropriate salary level to support retention and recruitment of Executive Directors. 

Operation 

Executive Directors receive the same annual salary. 

 Base salaries are reviewed annually on 1 January with regard to the external economic environment and 
salary adjustments across the Company.

 The salaries of the Chief Executive Officer (CEO) and Chief Commercial Officer (CCO) are designated 
in sterling but paid in local currencies. The salaries are re-based annually to allow for differentials arising 
through foreign exchange. 

Opportunity 

Salary increases will be awarded taking into account the outcome of the review. 

 Salary increases will usually be in line with increases awarded to other employees but the Committee may 
make additional adjustments where there has been a change in role or responsibilities or to reflect a gap in 
market positioning.

Performance metrics  

Not applicable for base salaries.

Pension	and	Benefits	

Purpose and link to strategy  

 To provide an appropriate range of benefits and pension contributions to assist in the attraction and 
retention of the calibre of Executive Directors required for delivery of corporate and strategic objectives.

Operation  

 The CEO, based in the U.S., does not receive any benefits or employer contributions to a pension plan.

 The Chief Financial Officer and Chief Development Officer (CFO & CDO), based in the UK, has income 
protection, life assurance cover and private medical insurance. Benefits are administered internally and a 
review of providers and prices is conducted annually through a broker to ensure that the level of rates and 
cover remain competitive. A matching employer contribution of up to 5% of annual base salary is made to 
the Group personal pension plan. 

 The CCO, based in Canada, has private medical and dental insurance and life assurance cover. He does 
not receive any employer pension contributions to a pension plan.

Opportunity  

 The benefits and pension packages, which are tailored to the individual Executive Directors, are set at a 
level that the Committee considers is appropriate. 

The value of benefits will vary each year according to the cost of provision.

Performance metrics 

Not applicable for benefits and pension package. 

Annual Bonus 

Purpose and link to strategy  

To reward the achievement of corporate targets.

Operation  

Objectives are set as early as possible in the financial year. 

 The bonuses may be paid in cash and/or shares after the end of the financial year to which they relate.

Opportunity  

 The annual bonus award is determined as a percentage of base salary based on performance against 
pre-agreed objectives. When deciding on the level of bonus awards, the Committee will have regard to 
the extent to which achievement of the objectives has contributed to progress against the Company’s 
strategic drivers.

The bonus is contractual but at the discretion of the Committee.

The maximum bonus potential for Executive Directors is 100% of salary. 

Performance metrics  

 The targets for the Executive Directors comprise the corporate, strategic and financial objectives 
agreed by the Board. There are no individual objectives.

 The Committee uses its judgement, supported by measurable evidence, to decide the extent to which 
the objectives have been achieved and exercises its discretion to decide on the level of bonus awards 
to be paid.

 The Committee considers whether operations have been completed to acceptable HSE standards and 
considers whether there were any HSE incidents when considering the level of bonus payments.

Share Option Plan (Option Plan)

Purpose and link to strategy 

To support alignment with shareholders through the link to the creation of shareholder value. 

Operation  

The Option Plan was introduced in 2018 to replace historical long-term incentive arrangements.

 The Committee makes awards of options at an exercise price based on the prevailing market price of the 
Company’s shares as at the date of grant. The options will vest in equal tranches after one, two and three 
years’ further continuous employment subject to leaver provisions. Options granted to Executive Directors 
in July 2023 will cliff-vest after three years and will have a one year holding period post-vesting.

Opportunity  

 Option awards are usually made for a three-year term but the Committee has discretion over the 
frequency and quantum of awards. 

Performance metrics 

None.

Further Details on the Policy
Performance measurement
Annual bonus – the annual bonus is based on a range of corporate objectives that the Board have agreed are key to progressing and 
delivering the Company’s strategy. These can be operational, strategic and financial. Performance targets are designed to be stretching but 
achievable having regard to the Company’s strategic priorities from time to time. 

Option Plan – the Option Plan ensures alignment with shareholders being focused on share price growth over the medium to long term. 
Vesting of equity awards is phased with options vesting in equal tranches in years 1, 2 and 3 after the date of grant. Options granted in 
exchange for options in predecessor companies at the time of the Merger vest in accordance with the terms of the original option grant. The 
Option Plan for the Executive Directors is the same as that for all other employees. 

Remuneration policy for other employees and consultation
The Company’s policy for all employees is to provide remuneration packages that reward them fairly for their contribution and role within the Company. 

All employees are entitled to receive the full range of Company benefits but with different qualifying periods and levels of cover depending on 
seniority. The most senior employees below Board level are eligible to receive an annual bonus based on performance against corporate targets. 

All permanent employees have been granted options under the Option Plan on the same terms as the Executive Directors but proportionate 
to their employment contracts and their ability to contribute towards the Company’s strategic objectives. This ensures that an element of 
remuneration is deliverable through a scheme that aligns participants with shareholders. 

The Company does not consult with employees on the effectiveness and appropriateness of the policy but, in considering individual salary 
increases, the Committee does have regard to salary increases across the Company. 

Recruitment 
In the case of recruiting a new Executive Director, the Committee can use all the existing components of remuneration as set out in the policy table. 

The salary of a new appointee will be determined by reference to the experience and skills of the individual, market data, internal comparatives 
and the candidate’s current remuneration. New appointees may be entitled to receive the full range of Company benefits on joining and, if the 
Committee considers it appropriate, a matching employer contribution of up to 5% of annual base salary to the Group personal pension plan. 

In relation to any elements of variable pay, the Committee will take the following approach:

Component 

Annual Bonus 

Option Plan 

Approach 

 The annual bonus would operate as  
outlined in the Policy for existing Executive  
Directors. The relevant maximum will be pro-rated  
to reflect the period of employment over the year.  
Consideration will be given to the appropriate  
performance targets at the time of joining. 

 The Option Plan would operate as outlined  
in the policy for existing Directors. An award of  
options may be granted on joining subject to the  
Company being in an open dealing period. 

Maximum annual opportunity 

100% of base salary in respect of the  
current financial year.

The Directors’ service contracts are available to view at the Company’s registered office and prior to each Annual General Meeting at 
the venue for the meeting. 

The notice period for the Executive Directors is six months’ notice in writing by either party. The Company has the right to make 
a payment in lieu of notice of six months’ salary and, in the case of the CEO, a reimbursement of certain benefits if relevant. The 
Committee will consider termination payments on a case-by-case basis. It will consider the terms of the Director’s contract and the 
circumstances of the termination and might consider making an ex-gratia payment where the circumstances and/or a Director’s 
contribution to the Company justifies this. If an ex-gratia payment is to be made, the Committee will ensure that it is satisfied that it is in 
the best interests of the Company to make such a payment and that there is no “reward for failure”.

The Committee also has discretion to settle any other amounts which it considers are reasonably due to the Director such as where the 
parties agree to enter into a settlement agreement and the individual is required to seek independent legal advice. The Committee can 
approve new contractual arrangements with a departing Director covering matters such as confidentiality or restrictive covenants and/or 
consultancy arrangements where it believes this is in the best interests of the Company.

Treatment of incentives for leavers and following a corporate event

In relation to annual bonuses, a bonus payment will not usually be made if the Director is under notice at the bonus payment date or has

The Option Plan rules include malus and clawback provisions whereby the Committee has discretion to reduce the number of 
shares subject to an existing Option award in the event that an Option has been granted or has vested on the basis of any incorrect 
information relevant to the setting of any performance condition or condition of satisfaction including a material misstatement in the 
published financial results or in the event of fraud or misconduct by an Option holder including where an Option holder has been 
dismissed for cause. In the case of an Option which has been exercised, the Committee can require the Option holder to repay the 
Company an amount equal to the benefit by way of a transfer of shares or cash. 

The Board or Committee can amend the Option Plan rules at any time provided that an option holder’s existing rights cannot be 
adversely affected without the Option holder’s consent.

Additional Information in Respect of Single Figure Table of Remuneration for the Year Ended 31 December 2023
Base salaries 
During the year, the Committee considered the results of the A&M Executive Director compensation and benchmarking review. A&M 
benchmarked the remuneration packages of each of the Executive Directors against a peer group comprising AIM quoted companies 
with a similar market capitalisation to Invinity’s and concluded that the Executive Directors’ salaries and pension contribution levels 
were below market in each case. The Committee agreed that it was appropriate to increase the Executive Directors’ base salaries and 
agreed the following adjustments with effect from 1 January 2023: 

Lawrence Zulch: £250,000 p.a.
Matthew Harper: £220,000 p.a.
Jonathan Marren: £220,000 p.a.

Chairman and Non-Executive Director fees
The fees for the Chairman and Non-Executive Directors had not been reviewed since the merger between redT energy PLC and 
Avalon Battery Corporation in April 2020 or the date of appointment in the case of Rajat Kohli and Kristina Peterson. The Board of 
Directors considered the outcome of the benchmarking exercise undertaken by A&M and agreed the following adjustments to fees 
with effect from 1 January 2023: 

Chairman fee: £72,000 
Non-Executive Director basic fee: £40,000
Committee membership fee (except Nomination Committee): £2,500

Annual bonus
In respect of the financial period, the Committee agreed that the Executive Director annual bonus opportunity would be up to 100% 
of base salary. The Committee had agreed objectives with a range of weightings relating to gross revenue, closing cash, share price 
target and next-generation product rollout. 

The Committee concluded that the final bonus calculation for 2023 was 50%.

Awards of share options during the financial year
The Board considered the outcome of the A&M benchmarking review in respect of long-term incentives which concluded that the 
Executive Directors’ long-term incentives opportunity was significantly below market and noted that the CEO had not received any share 
options since joining the Company. The Board agreed that it was appropriate to make a one-off grant of share options to cover the next 
three performance years with three-year cliff vesting at the end of the performance period and a one year holding period post vesting 
subject to continued employment. The table below summarises the options granted to Executive Directors during the financial year.

Implementation of Executive Director Remuneration Policy for 2024
Base salaries
The Committee agreed that a company-wide 4% salary increase effect from 1 June 2024 would also apply to the Executive Directors’ salaries. 
This increase was implemented to assist staff with the rising cost of living due to inflationary pressure in the UK, the U.S. and Canada.  

Annual bonus
For 2024, the Executive Directors’ annual bonus will be determined as a percentage of base salary based on performance against pre-agreed 
corporate objectives. The maximum bonus potential is 100% of base salary with on target bonuses being 50%. 

For the financial year ending 31 December 2024, the Committee has agreed objectives with a range of weightings relating to gross 
revenue, fundraising, next-generation product rollout and delivery, product development partnerships and UK project development. 

Option Plan
The Committee does not plan to make any awards of share options to Executive Directors under the Option Plan during the 2024 financial year. 

Benefits and pension contributions 
The Executive Directors will receive the benefits and pension contributions in line with the policy.

Implementation of Non-Executive Director Remuneration Policy for 2024
No adjustments to Non-Executive Director fees are planned for the 2024 financial year.

Statement of Directors’ responsibilities
in respect of the Financial Statements

Legal and Regulatory Framework 
The Directors are responsible for preparing the Annual Report 
and financial statements in accordance with applicable law 
and regulations. As a Company incorporated in Jersey and 
with its ordinary shares admitted to trading on the Alternative 
Investment Market (AIM) of the London Stock Exchange and on 
the APEX segment of the AQSE Growth Market of AQSE, the 
Company is subject to the FCA’s Listing Rules and Disclosure 
and Transparency Rules, as well as to all applicable laws and 
regulations in Jersey. 

The Directors are also responsible for the maintenance and 
integrity of the corporate and financial information included on 
the Company’s website. Legislation in the Jersey governing the 
preparation and dissemination of financial statements may differ 
from legislation in other jurisdictions. 

Responsibility Statement 
Each of the Directors, whose names and functions are listed in 
the Corporate Governance section – Board of Directors on pages 
22-23, confirm that to the best of their knowledge that:   

 the Financial Statements, which have been prepared in 
accordance with IFRS, give a true and fair view of the assets, 
liabilities, financial position and loss of the Company taken as 
a whole;  
 the Strategic Report includes a fair review of the development 
and performance of the business and the position of the 
Company taken as a whole, together with a description of the 
principal risks and uncertainties that it faces; and  
 the Annual Report and Financial Statements, taken as a 
whole, are fair, balanced and understandable and provide 
the information necessary for shareholders to assess the 
Company’s position and performance, business model 
and strategy. 

In the case of each director in office at the date the Directors’ 
report is approved:

 so far as the Director is aware, there is no relevant audit 
information of which the Company’s auditors are unaware; 
and  
 they have taken all the steps that they ought to have taken as 
a Director in order to make themselves aware of any relevant 
audit information and to establish that the Company’s auditors 
are aware of that information. 

This responsibility statement was approved by the Board of 
Directors and is signed on its behalf by: 

Jonathan Marren
Chief Financial Officer and Chief Development Officer
26 June 2024

The Companies (Jersey) Law 1991 requires the Directors to 
prepare financial statements for each financial year. Under that 
law, the Directors have prepared these Financial Statements 
under International Accounting Standards (“IAS UK”) as adopted 
in the United Kingdom. 

Under Jersey company law, the Directors must not approve the 
financial statements unless they are satisfied that they give a true 
and fair view of the state of affairs of the Company and of the 
profit or loss of the Company for that period. 

In preparing these Financial Statements, the Directors should: 

 select suitable accounting policies and then apply them 
consistently;  
 state whether applicable IFRS have been followed, subject 
to any material departures disclosed and explained in the 
Financial Statements;  
 make judgements and accounting estimates that are 
reasonable and prudent; and  
 prepare the Financial Statements on the going concern basis 
unless it is inappropriate to presume that the Group  
will continue as a going concern. 

The Directors are responsible for keeping adequate accounting 
records that are sufficient to show and explain the Company’s 
transactions and disclose with reasonable accuracy at any 
time the financial position of the Company and enable them 
to ensure that the Financial Statements comply with the 
Companies (Jersey) Law 1991. They are also responsible for 
safeguarding the assets of the Company and hence for taking 
reasonable steps for the prevention and detection of fraud and 
other irregularities. 

The Directors are responsible for preparing the Annual Report 
and financial statements, which includes a Strategic Report, 
Directors’ Report, Directors’ Remuneration Report and 
Corporate Governance Statement that comply with applicable 
laws and regulations.

Annual Report and Financial Statements 2023

Invinity Energy Systems plc 

Invinity Energy Systems plc Annual Report and Financial Statements 2023Independent Auditors’ Report
to the Members of Invinity Energy Systems plc

Opinion on the Financial Statements
In our opinion:

 the financial statements give a true and fair view of the state of the Group’s affairs as at 31 December 2023 and of the Group’s loss for 
the year then ended;
the Group financial statements have been properly prepared in accordance with UK adopted international accounting standards; and

  have been prepared in accordance with the requirements of Companies (Jersey) Law 1991.

We have audited the financial statements of Invinity Energy Systems Plc (the ‘Group’) for the year ended 31 December 2023 which 
comprise the consolidated statement of profit and loss, the consolidated statement of financial position, the consolidated statement of 
changes in equity, the consolidated statement of cash flows and notes to the financial statements, including a summary of material 
accounting policy information. The financial reporting framework that has been applied in their preparation is applicable law and UK 
adopted international accounting standards.

Basis for Opinion
We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities 
under those standards are further described in the Auditor’s responsibilities for the audit of the financial statements section of our report. 
We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. 

Independence
We remain independent of the Group in accordance with the ethical requirements that are relevant to our audit of the financial statements 
in the UK, including the FRC’s Ethical Standard as applied to listed entities, and we have fulfilled our other ethical responsibilities in 
accordance with these requirements. 

Conclusions Relating to Going Concern
In auditing the financial statements, we have concluded that the Directors’ use of the going concern basis of accounting in the preparation 
of the financial statements is appropriate. Our evaluation of the Directors’ assessment of the Group’s ability to continue to adopt the 
going concern basis of accounting included:

 We evaluated the Directors papers assessing going concern for the forecast period, including the Director’s assessment of risks 
and uncertainties, together with the supporting cash flow forecasts prepared by the Directors. In doing so, we formed our own 
assessment of risks and uncertainties based on our understanding of the business and current economic conditions; 
 We examined the cash flow forecasts and challenged the significant assumptions made by the Directors in preparing the 
projections including comparing revenue from contracts to business plans and budget;
 Where available, we obtained signed contracts on supply of batteries underlying expected future cash flows, enquired with Chief 
Commercial Officer on the project pipeline, future capital program and ability to meet the rollout targets as per product road map, 
compared forecast costs of sale to budgets, compared projected contract margins with actual margins. In addition, we evaluated 
the forecast of general and administrative costs to recent actuals; 
 We reviewed the forecast data to actual results post year-end and latest available cash position as of 31 May 2024;
 We examined evidence related to received gross proceeds in the amount of £57.4 million from a share offering subsequent to 
year-end. We inspected the terms relevant to this offering to conclude on whether any restrictions may be placed on the Directors’ 
ability to use the related funds to support their operation;
 We considered the Director’s sensitivity analysis and performed our own sensitivity analysis on the forecasts in respect of 
discretionary spending in adverse scenarios of lower sales compared to base case scenario and ran stress tests to estimate cash 
balances through the going concern period in the scenario of reduced sales; and
 We reviewed the adequacy of the disclosures in the financial statements in respect of going concern based on the results of our 
evaluation.

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually 
or collectively, may cast significant doubt on the Group’s ability to continue as a going concern for a period of at least twelve months from 
when the financial statements are authorised for issue.

An Overview of the Scope of Our Audit
Our Group audit was scoped by obtaining an understanding of the Group and its environment, including the Group’s system of internal 
control,  and  assessing  the  risks  of  material  misstatement  in  the  financial  statements.  We  also  addressed  the  risk  of  management 
override of internal controls, including assessing whether there was evidence of bias by the Directors that may have represented a risk 
of material misstatement.

We  identified  five  significant  components,  being  Invinity  Energy  Systems  Plc  (Parent  Company),  Invinity  Energy  (UK)  Ltd.,  Invinity 
Energy Systems (Ireland) Ltd., Invinity Energy Systems (Canada) Ltd. and Invinity Energy Systems (U.S.) Ltd. The Group Audit team 
performed full scope of audit of the Parent Company, Invinity Energy (UK) Ltd. and Invinity Energy Systems (Ireland) Ltd. The Canadian 
and U.S. subsidiaries (Invinity Energy Systems (U.S.) Ltd. and Invinity Energy Systems (Canada) Ltd.) were subject to a full scope audit 
by a BDO member firm. The remaining non-significant components were subject to analytical review. 

Our involvement with component auditors
For the work performed by component auditors, we determined the level of involvement needed in order to be able to conclude whether 
sufficient appropriate audit evidence has been obtained as a basis for our opinion on the Group financial statements as a whole. Our 
involvement with component auditors included the following:

 Detailed Group reporting instructions were sent to the component auditor, which included the significant areas to be covered by the 
audit (including Revenue Recognition that was considered to be a key audit matter as detailed below) and set out the information 
required to be reported to the Group audit team. 
 We performed both remote and on-site reviews of the component audit file in Canada using our online audit software platform and 
held regular calls and video-conferences with the component audit team. In addition, we visited Canada to meet with the component 
auditor and component management to consider relevant audit findings and conclusions. 
 The Group audit team was actively involved in the direction of the audits performed by the component auditor for Group reporting 
purposes,  along  with  the  consideration  of  findings  and  determination  of  conclusions  drawn.  We  performed  our  own  additional 
procedures in respect of the significant risk areas that represented Key Audit Matters in addition to the procedures performed by the 
component auditor.

Key audit matters
Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements 
of the current period and include the most significant assessed risks of material misstatement (whether or not due to fraud) that we 
identified,  including  those  which  had  the  greatest  effect  on:  the  overall  audit  strategy,  the  allocation  of  resources  in  the  audit,  and 
directing the efforts of the engagement team. These matters were addressed in the context of our audit of the financial statements as a 
whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Key Audit Matter 

Revenue Recognition
(Notes 2 and 4)
Key audit matters

Revenue generated for the year ended 
31 December 2023 amounted to £22.0 million 
(2022: £3.6 million). 

The Directors are required to assess 
whether performance obligations under 
contractual arrangements were met for 
each individual contract scenario. There are 
certain complexities inherent to contractual 
arrangements and, in particular, delivery 
terms and bill-and-hold arrangements. This, 
as a result, increases the risk that the cut-off 
of revenue is inappropriately applied. Based 
on the above, this is deemed to be a Key 
Audit Matter. 

How the Scope of Our Audit Addressed the Key Audit Matter

   We obtained the listing of revenue 
transactions and selected 100% of the 
reported transactions for testing. We obtained 
signed revenue agreements related to 
each transaction and reviewed their terms, 
including delivery terms, volume and pricing;
   We obtained evidence regarding transfer 
of control, including shipping documents, 
correspondence with customers evidencing 
acceptance of the product by the customer 
and other relevant documents, evidencing 
meeting performance obligations under 
related agreement terms and, in particular, 
terms of delivery. 
   Performed a cut-off test of revenue 
transactions, including revenue recognised 
in respect of goods in transit by inspecting 
related documentation and correspondence 
for evidence of customers’ acceptance. 
We examined supporting contracts of sale 
to confirm the point at which control over 
the underlying inventory transferred to 
the customer including review of related 
terms of delivery based on Incoterms. 
Where applicable, we also corroborated the 
evidence by reviewing associated freight, 
insurance and other applicable arrangements 
related to the delivery of the product.
   We traced the movement of inventory to 
the cost of sales ledger to confirm that 
related cost of sales has been appropriately 
recognised pre and post year end;
   For bill and hold arrangements for which 
revenue was recognised during the year, we 
obtained Directors’ assessment supporting 
the recognition of revenue, inspected related 
documentation and correspondence for 
evidence of customers’ acceptance of the 
product. Where applicable, we corroborated 
the evidence by reviewing associated 
storage and insurance arrangements. Based 
on the above we concluded on whether the 
revenue recognised, where bill and hold 
arrangements were present, meets the 
requirements per IFRS 15; and 
   We examined financial statements 
disclosures and accounting policies for 
compliance with IFRS 15.

Key observations:
Based on the audit procedures performed we 
considered that revenue recognised in the year 
is appropriate.

UK  /  U.S.  /  CANADA  /  AUSTRALIAFINANCIAL STATEMENTSAnnual Report and Financial Statements 2023Our Application of Materiality
We apply the concept of materiality both in planning and performing our audit, and in evaluating the effect of misstatements. We consider 
materiality to be the magnitude by which misstatements, including omissions, could influence the economic decisions of reasonable 
users that are taken on the basis of the financial statements. 

In order to reduce to an appropriately low level the probability that any misstatements exceed materiality, we use a lower materiality level, 
performance materiality, to determine the extent of testing needed. Importantly, misstatements below these levels will not necessarily 
be evaluated as immaterial as we also take account of the nature of identified misstatements, and the particular circumstances of their 
occurrence, when evaluating their effect on the financial statements as a whole. 

Based on our professional judgement, we determined materiality for the financial statements as a whole and performance materiality 
as follows: 

Key Audit Matter 

Materiality

Group Financial Statements
2023
£m

0.33

Basis for determining materiality

1.5% of Revenue

Rationale for the benchmark  
applied

The Group is in a loss making position and focused on expanding revenue. 
Revenue is considered to be an appropriate materiality benchmark and 
constitutes a key performance measure.

Performance materiality

0.2

Basis for determining  
performance materiality

60% of overall materiality

Rationale for the percentage applied  
for performance materiality

Given the nature of business activity, a lower level of performance 
materiality was considered appropriate.

For the purposes of our Group audit opinion, we set materiality for each significant component of the Group based on a percentage 
of between 30% and 90% of Group materiality dependent on the size and our assessment of the risk of material misstatement of that 
component. Component materiality ranged from £100k to £300k. In the audit of each component, we further applied performance 
materiality levels of 60% of the component materiality to our testing to ensure that the risk of errors exceeding component materiality 
was appropriately mitigated.

Reporting threshold 
We agreed with the Audit Committee that we would report to them all individual audit differences in excess of £6,600. We also agreed 
to report differences below this threshold that, in our view, warranted reporting on qualitative grounds.

Other Information
The Directors are responsible for the other information. The other information comprises the information included in the Annual Report 
and Financial Statements other than the financial statements and our auditor’s report thereon. Our opinion on the financial statements 
does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of 
assurance conclusion thereon. 

Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent 
with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If 
we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to 
a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a 
material misstatement of this other information, we are required to report that fact.

We have nothing to report in this regard.

46

Invinity Energy Systems plc Annual Report and Financial Statements 2023Other Companies (Jersey) Law 1991 Reporting
We have nothing to report in respect of the following matters where the Companies (Jersey) Law 1991 requires us to report to you if, in 
our opinion:

 proper accounting records have not been kept, or proper returns adequate for our audit have not been received from branches not 
visited by us; or
the financial statements are not in agreement with the accounting records and returns; or

  we have not received all the information and explanations we require for our audit.

Responsibilities of Directors 
As explained more fully in the Directors responsibilities statement, the Directors are responsible for the preparation of the financial 
statements and for being satisfied that they give a true and fair view and for such internal control as the Directors determine is necessary 
to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the Directors are responsible for assessing the Company’s ability to continue as a going concern, 
disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the Directors either 
intend to liquidate the Company or to cease operations, or have no realistic alternative but to do so. 

Auditor’s Responsibilities for the Audit of the Financial Statements 
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, 
whether  due  to  fraud  or  error,  and  to  issue  an  auditor’s  report  that  includes  our  opinion.  Reasonable  assurance  is  a  high  level  of 
assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement 
when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could 
reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

Extent to which the audit was capable of detecting irregularities, including fraud
Irregularities,  including  fraud,  are  instances  of  non-compliance  with  laws  and  regulations.  We  design  procedures  in  line  with  our 
responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our 
procedures are capable of detecting irregularities, including fraud is detailed below:

Non-compliance with laws and regulations
We obtained an understanding of the legal and regulatory frameworks that are applicable to the Group. We determined that the most 
significant which are directly relevant to specific assertions in the financial statements are those related to the reporting framework (UK 
adopted international accounting standards, the Companies (Jersey) Law 1991, the AIM rules and the QCA Corporate Governance 
Code) and local taxation legislation in the countries where the Group operates, and the terms and requirements included in the Group’s 
operating and exploration licences.

Our audit procedures included the following:

 Reviewing the financial statement disclosures and testing to supporting documentation to assess compliance with the relevant 
laws and regulations noted above.
 Enquiries of Management, the Audit Committee of any known or suspected instances of non-compliance with laws and 
regulations;
 Reading minutes of meetings of those charged with governance, and reviewing correspondence with local tax and regulatory 
authorities to identify potential litigation and claims and non-compliance with laws and regulations;
 Performing a review of local and international tax compliance with the involvement of our tax specialists;
 Reviewing of legal expenditure accounts to understand the nature of expenditure incurred and obtaining external legal 
confirmations, where applicable.

Fraud
We assessed the susceptibility of the financial statements to material misstatement, including fraud. Our risk assessment procedures 
included:

 Enquiring of Management and the Audit Committee of known or suspected instances of fraud, potential litigation and claims. 
We read minutes of meetings of those charged with governance, and reviewed correspondence with local tax and regulatory 
authorities;
 Holding discussions within the audit engagement team as to how and where fraud might occur in the financial statements and 
where any potential indicators of fraud may arise in the Group in order to consider how our audit strategy should reflect our 
considerations;
 Testing the appropriateness of journal entries made throughout the year, to supporting documentation, by applying specific criteria 
to detect possible irregularities or fraud;

47

UK  /  U.S.  /  CANADA  /  AUSTRALIAFINANCIAL STATEMENTSAnnual Report and Financial Statements 2023 
 
 
 
 
 
 
 
 
 
 
 Assessing and challenging key areas of judgement and estimation made by Management and the Directors, including the 
accounting policy over revenue recognition and its application (see Key Audit Matter above), the Directors’ assessment of the 
going concern position of the Group and key accounting estimates;
 Performing substantive testing on revenue to ensure that cut-off was appropriately applied (see Key Audit Matter above); 
 Undertaking unpredictability testing through substantive work on a number of selected general ledger balances; 
 Obtaining an understanding of, and evaluating the design and implementation of, relevant controls surrounding the financial 
reporting close process such as controls over the posting of journals and the consolidation process and obtaining an 
understanding of the segregation of duties in these processes;

With regards to compliance with laws and regulations at the component level, we instructed the component auditor to report to us on any 
instances of non-compliance with local laws and regulations that could result in a risk of material misstatement in the Group financial 
statements. We reviewed the component auditor’s working papers over laws and regulations compliance.

We also communicated relevant identified laws and regulations and identified fraud risks to all engagement team members (including 
component engagement teams) and remained alert to any indications of fraud or non-compliance with laws and regulations throughout 
the audit. For component engagement teams, we also reviewed the result of their work performed in this regard.

Our audit procedures were designed to respond to risks of material misstatement in the financial statements, recognising that the risk of 
not detecting a material misstatement due to fraud is higher than the risk of not detecting one resulting from error, as fraud may involve 
deliberate concealment by, for example, forgery, misrepresentations or through collusion. There are inherent limitations in the audit 
procedures performed and the further removed non-compliance with laws and regulations is from the events and transactions reflected 
in the financial statements, the less likely we are to become aware of it.

A further description of our responsibilities is available on the Financial Reporting Council’s website at: 
https://www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report.

Use of Our Report
This report is made solely to the Company’s members, as a body, in accordance with Article 113A of the Companies (Jersey) Law 1991. 
Our audit work has been undertaken so that we might state to the Company’s members those matters we are required to state to them in 
an auditor’s report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone 
other than the Company and the Company’s members as a body, for our audit work, for this report, or for the opinions we have formed.

Notes to the Consolidated Financial Statements  
for the year ended 31 December 2023

1 General Information
Invinity Energy Systems plc (the ‘Company’) is a public company limited by shares incorporated and domiciled in Jersey. The registered 
office address is Third Floor, IFC5, Castle Street, St. Helier, JE2 3BY, Jersey.

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. 

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
Basis of preparation
These  consolidated  financial  statements  have  been  prepared  in  accordance  with  International  UK-adopted  International Accounting 
Standards, the associated interpretations issued by the IFRS Interpretations Committee (together ‘IFRS’) and in accordance with the 
Companies (Jersey) Law 1991.

Separate presentation of the parent company financial statements is not required by the Companies (Jersey) Law 1991 and, accordingly, 
such statements have not been included in this report.

The significant accounting policies applied in preparing these consolidated financial statements are set out below. These policies have 
been consistently applied throughout the period and to each subsidiary within the Group.

The financial statements have been prepared under the historical cost convention except where stated.

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 £53.2 million as at 31 May 2024 (2022: £15.4 million).

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.

New standards, amendments and interpretations effective and adopted by the Group in 2023
Amendments to existing standards previously issued by the IASB with effective dates during the year ended 31 December 2023 are 
summarised below. There was no effect on the Group’s consolidated financial statements for the year ended 31 December 2023 as a 
result of the adoption of these amendments.

IFRS 17 Insurance Contracts
The Group has adopted IFRS 17 and the related amendments for the first time in the current year. IFRS 17 establishes the principles for 
the recognition, measurement, presentation and disclosure of insurance contracts and supersedes IFRS 4 Insurance Contracts.

IFRS 17 outlines a general model, which is modified for insurance contracts with direct participation features, described as the variable fee 
approach. The general model is simplified if certain criteria are met by measuring the liability for remaining coverage using the premium 
allocation approach. The general model uses current assumptions to estimate the amount, timing and uncertainty of future cash flows and it 
explicitly measures the cost of that uncertainty. It considers market interest rates, and the impact of policyholders’ options and guarantees. The 
Group does not have any contracts that meet the definition of an insurance contract under IFRS 17.

UK  /  U.S.  /  CANADA  /  AUSTRALIAFINANCIAL STATEMENTSAnnual Report and Financial Statements 2023Notes to the Consolidated Financial Statements 
continued for the year ended 31 December 2023

Amendments to ‘IAS 1 Presentation of Financial Statements and IFRS Practice Statement 2 – Making Materiality Judgements – Disclosure 
of Accounting Policies’
The Group has adopted the amendments to IAS 1 for the first time in the current year. The amendments change the requirements in 
IAS 1 with regard to disclosure of accounting policies. The amendments replace all instances of the term ‘significant accounting policies’ 
with ‘material accounting policy information’. Accounting policy information is material if, when considered together with other information 
included in an entity’s financial statements, it can reasonably be expected to influence decisions that the primary users of general-purpose 
financial statements make on the basis of those financial statements.

The supporting paragraphs in IAS 1 are also amended to clarify that accounting policy information that relates to immaterial transactions, 
other events or conditions is immaterial and need not be disclosed. Accounting policy information may be material because of the nature 
of the related transactions, other events or conditions, even if the amounts are immaterial. However, not all accounting policy information 
relating to material transactions, other events or conditions is itself material.

The IASB has also developed guidance and examples to explain and demonstrate the application of the ‘four-step materiality process’ 
described in IFRS Practice Statement 2.

Amendments to ‘IAS 12 Income Taxes – Deferred Tax related to Assets and Liabilities arising from a Single Transaction’
The Group has adopted the amendments to IAS 12 for the first time in the current year. The amendments introduce a further exception 
from the initial recognition exemption. Under the amendments, an entity does not apply the initial recognition exemption for transactions 
that give rise to equal taxable and deductible temporary differences. Depending on the applicable tax law, equal taxable and deductible 
temporary differences may arise on initial recognition of an asset and liability in a transaction that is not a business combination and affects 
neither accounting profit nor taxable profit. Following the amendments to IAS 12, an entity is required to recognise the related deferred tax 
asset and liability, with the recognition of any deferred tax asset being subject to the recoverability criteria in IAS 12.

Amendments to ‘IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors – Definition of Accounting Estimates’
The Group has adopted the amendments to IAS 8 for the first time in the current year. The amendments replace the definition of a change 
in accounting estimates with a definition of accounting estimates. Under the new definition, accounting estimates are “monetary amounts in 
financial statements that are subject to measurement uncertainty”. The definition of a change in accounting estimates was deleted.

New standards and interpretations not yet adopted 
Certain new accounting standards and interpretations have been published that are not mandatory for 31 December 2023 reporting 
periods and have not been early adopted by the Company. These standards are not expected to have a material impact on the entity in 
the current or future reporting periods or on foreseeable future transactions and are summarised below: 

IAS 1 Classification of Liabilities as Current or Non-Current (effective for periods beginning on or after 1 January 2024);
 IFRS 10 and IAS 28 Sale or Contribution of Assets between an Investor and its Associate or Joint Venture (the effective date of the 
amendments has yet to be set by the IASB);
IAS 1 Non-current Liabilities with Covenants (effective for periods beginning on or after 1 January 2024);
IAS 7 and IFRS 7 Supplier Finance Arrangements (effective for periods beginning on or after 1 January 2024); and
IFRS 16 Lease Liability in a Sale and Leaseback (effective for periods beginning on or after 1 January 2024)

Foreign currency
Presentation currency
The consolidated financial statements are presented in Great British Pounds (GBP) rounded to the nearest thousand (£000), except 
where otherwise indicated. 

Functional currency 
Items included in the financial information of the individual companies that comprise the Group are measured using the currency of the 
primary economic environment in which each subsidiary operates (its functional currency).

Whilst Jersey uses the Jersey Pound as its currency, Jersey is in a currency union with the United Kingdom and so the functional currency 
of the parent company of the Group has been determined to be GBP.

Foreign currency transactions
Transactions  in  currencies  other  than  an  entity’s  functional  currency  (foreign  currencies)  are  translated  using  the  exchange  rate  on 
the date of the transaction. Foreign exchange gains and losses resulting from the settlement of transactions denominated in a foreign 
currency are translated into functional currency using the relevant exchange rate at the date of the transaction.

Foreign  exchange  gains  and  losses  resulting  from  the  settlement  of  foreign  currency  transactions  and  from  the  translation  at  the 
balance sheet date of monetary assets and liabilities denominated in foreign currencies, are recognised in the consolidated statement of 
comprehensive loss within gains/(losses) on foreign currency transactions.

Foreign currency gains/(losses) realised on the retranslation of subsidiaries as part of the year-end consolidation are recorded in the 
translation reserve that forms a part of shareholders’ funds in the consolidated financial statements of the Group.

Consolidation of subsidiaries
Subsidiaries are all entities over which the Company has control. The Company controls an entity when it is exposed to, or has rights 
over, variable returns from its involvement with the entity and can affect those returns through its ability to exercise control over the entity. 
Subsidiaries are consolidated in the Group financial statements from the date at which control is transferred to the Company. 

Subsidiaries are deconsolidated from the date that control ceases. The ability to control an entity may cease because of the sale of a 
subsidiary or other change in the Company’s shareholding in that subsidiary, voting rights or board representation.

Foreign currency operations
Subsidiaries of the Company may have functional currencies that are different from that of the Company. Since the Group financial 
statements are presented in GBP, the assets and liabilities of foreign currency subsidiaries consolidated into these financial statements 
are translated into the Group’s presentational currency using exchange rates prevailing at the end of the reporting period. Income and 
expense items are similarly translated using the average rate for each month during the year. The exchange rates on the actual dates 
of transactions are used where exchange rates fluctuate significantly within a month. Exchange differences arising on consolidation are 
recognised in other comprehensive income and are accumulated as part of shareholder’s equity.

Transaction between entities within the Group
Transactions and balances between companies forming part of the Group together with any unrealised income and expenses arising from 
intra-group transactions are eliminated in the preparation of the consolidated financial statements of the Group.

Operating segments
The Group is organised internally to report to the Executive Directors as a whole. The Executive Directors comprise the Chief Executive 
Officer, the Chief Commercial Officer, and the Chief Financial Officer and Chief Development Officer. The Executive Directors, as a 
group, have been determined, collectively, to prosecute the role of chief operating decision maker of the Group. The chief operating 
decision maker is ultimately responsible for entity-wide resource allocation decisions, the evaluation of the financial, operating and ESG 
performance of the Group.

The Group’s activities have been determined to represent a single operating segment being the provision of vanadium flow batteries and 
ancillary services, principally comprising installation and integration services, and the provision of extended warranties for battery units sold.

Revenue
The Group generates revenue from the sale of battery storage systems integration hardware, installation, extended warranty and other 
services. These multiple elements are separate performance obligations that are derived from contractual arrangements with customers. 
The sales contracts do not include a general right of return. 

For contracts that contain multiple elements or promises, the Group accounts for individual goods and services separately if they are 
distinct. A product or service is distinct if it is separately identifiable from other items in the agreement and where a customer can benefit 
from the good or service on its own or together with other resources that are readily available.

The consideration paid for each performance obligation is typically fixed. A significant portion of the aggregate payment due under a 
contract for sale is normally due before delivery or completion of the service. The total consideration under the contract is allocated 
between the distinct performance obligations contained in the contract based on their stand-alone selling prices. The stand-alone selling 
price  is  estimated  using  an  adjusted  market  assessment  approach  that  looks  to  industry  benchmarks  or  pricing  surveys  for  certain 
standalone products or services.

55

UK  /  U.S.  /  CANADA  /  AUSTRALIAFINANCIAL STATEMENTSAnnual Report and Financial Statements 2023Notes to the Consolidated Financial Statements 
continued for the year ended 31 December 2023

The Group measures revenue based on the consideration specified in the contracts for sale with customers. Revenue is recognised 
when a performance obligation is satisfied by transferring control over a good or service to a customer. With respect to the battery system, 
associated control systems and integration hardware, control is transferred at a point in time and is usually based on the contractual 
shipping terms. In certain instances, the battery system and integration hardware may be ready for delivery although the customer is not 
ready to receive the product. The Group will recognise revenue in accordance with IFRS 15 as a Bill-and-Hold arrangement if all of the 
following conditions are satisfied:

   The reason for the bill and hold arrangement is substantive; 
   The battery systems and hardware are identified separately as belonging to the customer;
   The battery systems and hardware are currently ready for physical transfer to the customer; and
   The Company does not have the ability to use the product or to direct it to another customer.

With respect to the services that includes installation and commissioning, the performance obligation is usually satisfied at a point in time 
when a when a commissioning certificate or site performance report has been issued to the customer. Revenue excludes any taxes such 
as sales taxes, value added tax or other levies that are invoiced and collected on behalf of third parties, such as government tax authorities. 

In addition, under the terms of its contracts for sale, the Group may be responsible for other services such as storing and delivering battery 
systems to its customers. When this is the case, the Group will invoice the relevant customer for, and will recognise as revenue, any charges 
incurred together with any associated handling costs. Revenue is recognised for the storage services over time as the services are delivered 
and for shipping services at a point in time when the goods are delivered to the agreed upon location. The related costs incurred by the Group 
for storage, shipping and handling services are recognised as cost of sales concurrent with the recognition of the associated revenue. 

Grant income
Government and other grants received are recognised in the consolidated statement of profit and loss in the period that the related 
expenditure is incurred. Grant income received in respect of costs incurred is presented net within the associated cost category. Capital 
grants are similarly netted against the relevant asset acquired or constructed.

Grant income received in advance of the associated expenditure is presented as deferred income within contract liabilities and released to 
profit and loss as the associated expenditure is incurred. Grant income receivable is presented as accrued income within contract assets 
until such time as it can be claimed or is received.

Finance income and costs
Finance income comprises interest on cash deposits, foreign currency gains and the unwind of discount on any assets that are carried at 
amortised cost. Interest income is recognised as it accrues using the effective interest rate method.

Finance costs include foreign currency losses and the unwind of the discount on any liabilities held at amortised cost, such as lease 
liabilities arising from lease contracts.

Employee benefits
Short-term benefits
Benefits provided to employees that are short-term in nature are recognised as expenses in the statement of profit and loss as the related 
service is provided. The principal short-term benefits given to employees are salaries, associated holiday pay and other periodic benefits 
such as healthcare and pension contributions made by the Group for the benefit of the employee. A liability is recognised for the amount 
expected to be paid under short-term cash bonus plans if there is either a present legal or constructive obligation to pay the amount and 
the amount can be reliably estimated.

Share-based payments
The  Group  operates  equity-settled  share-based  compensation  plans,  under  which  it  compensates  employees  for  services  rendered 
through the issue of equity instruments, deferred share awards or options to subscribe for ordinary shares of the Group. The fair value of 
the employee services received in exchange for the grant of the equity instruments, shares or options is recognised as an expense. The 
total amount to be expensed is determined by reference to the fair value of the options granted:

 including any market conditions (for example, the Group’s share price);
  excluding the impact of any service and non-market performance vesting conditions (for example, profitability, sales, growth targets, 
and the requirement to remain as an employee of the Group over a specified period); and
including the impact of any non-vesting conditions.

56

Invinity Energy Systems plc Annual Report and Financial Statements 2023  
  
  
Non-market performance and service conditions are included in the assumptions regarding the number of options that are expected to 
vest. The total expense is recognised over the vesting period, which is the period over which all the specified vesting conditions are to 
be satisfied.

In some circumstances, employees may provide services in advance of the grant date and therefore the grant date fair value is estimated 
for the purposes of recognising the expense during the period between service commencement and the grant date.

At the end of each reporting period, the Group revises its estimates of the number of options that are expected to vest based on the non-
market vesting conditions. It recognises the impact of the revision to original estimates, if any, in the consolidated statement of profit and 
loss, with a corresponding adjustment to equity. 

Any social security contributions payable in connection with the grant of the share options is considered an integral part of the grant itself, 
and the charge will be treated as a cash-settled transaction.

Taxes
The  total  tax  charge  or  credit  recognised  in  the  statement  of  profit  and  loss  comprises  both  current  and  deferred  taxes. Taxation  is 
recognised in the consolidated statement of profit and loss except to the extent that it relates to a business combination or items recognised 
directly in equity or other comprehensive income.

Current tax
The current tax charge is based on the taxable profit for the year. Taxable profit or loss is different from the profit or loss reported in 
the statement of profit and loss as it excludes items of income and/or expense that are taxable or deductible in other years (temporary 
differences) and it further excludes items that are never taxable nor deductible (permanent differences).

Deferred tax
Deferred tax is the tax that is expected to be payable or recoverable on differences between the carrying value of assets and liabilities in 
the financial statements and the corresponding value of those assets and liabilities used to calculate taxable profit or loss.

Deferred tax assets are recognised for all deductible temporary differences, the carry forward of unused tax credits and any unused tax 
losses. Deferred tax assets are recognised to the extent that it is probable that taxable profit will be available against which the deductible 
temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilised.

Deferred tax assets and liabilities are recognised using the liability method for all taxable temporary differences, except in respect of 
taxable temporary differences associated with investments in subsidiaries and associates. Where the timing of the reversal of temporary 
difference arising from such investment related assets and liabilities can be controlled and it is probable that the temporary difference will 
not reverse in the foreseeable future then the Group does not recognise deferred tax liabilities on these items. 

A deferred tax asset or liability is not recognised if a temporary difference arises on initial recognition of an asset or liability and, at the time 
of the transaction, affects neither the accounting profit nor taxable profit or loss. 

Current and deferred tax is calculated using tax rates and laws that have been enacted or substantively enacted at the balance sheet date. 
Deferred tax balances are presented on a gross basis. Refer to note 18, deferred tax balances.

Earnings per share
The Group presents basic and diluted earnings per share (“EPS”) data for its ordinary shares. Basic EPS is calculated by dividing the 
profit or loss attributable to ordinary shareholders of the Company by the weighted average number of ordinary shares outstanding during 
the year.

Diluted EPS is determined by adjusting the weighted average number of ordinary shares outstanding used in the EPS calculation to 
include all potentially dilutive ordinary shares, which, in the case of the Company, represents additional shares that could be issued in 
relation to ‘in-the-money’ convertible notes, warrants or share options.

The effects of anti-dilutive potential ordinary shares are ignored in calculating diluted EPS. Anti-dilution is when an increase in earnings per 
share or a reduction in loss per share would result from the exercise of such options, warrants or convertible instruments.

continued for the year ended 31 December 2023

Intangible assets
Goodwill
The Group allocates the fair value of the purchase consideration on the acquisition of a subsidiary to the assets acquired and liabilities 
assumed based on an assessment of fair value at the acquisition date. Any excess of purchase consideration is recognised as goodwill. 
Where goodwill is recognised, it is allocated to the cash generating units (CGUs) in a systematic manner reflective of how the Group 
expects to recover the value of the goodwill. Because the Group has been determined to consist of a single business unit, the carrying 
value of goodwill is tested for impairment based on the recoverable value of the Group as a whole.

Goodwill is tested for impairment on an annual basis, and the Group will also test for impairment at other times if there is an indication 
that an impairment may exist. Determining whether goodwill is impaired requires an estimation of the value-in-use of the CGU. The key 
estimates are therefore the selection of the suitable discount rates and the estimation of future growth rates which may depend on specific 
risks and the anticipated economic and market conditions related to the CGU.

As part of determining the value in use of the CGU, sensitivities have been considered on the underlying inputs included within the value-
in-use calculations used for impairment reviews and no impact exists on the carrying value of goodwill, given the headroom identified as a 
result of the impairment test. Goodwill is impaired where circumstances indicate that the recoverable amount of the underlying CGU may 
no longer support the carrying value of the CGU. An impairment charge is recognised in the statement of profit and loss for the period in 
which it is determined the goodwill is no longer recoverable. Impairment losses related to goodwill cannot be reversed in future periods.

Internally generated intangible assets – research and development costs
Research
Expenditure on research activities is recognised as an expense in the period in which it is incurred. Research activities are aimed at 
creating new knowledge or the use of existing knowledge in new or creative ways to generate new concepts. Research activity does not 
typically have a defined commercial objective at the outset. 

Development
Where projects evolve toward commerciality or are related to a specific commercial objective they are assessed to determine whether the 
activity constitutes development that is associated with a commercial objective or practical application. 

The associated costs represent development costs and can be capitalised if, and only if, the following conditions can be demonstrated:

 the technical feasibility of completing the intangible asset so that it can be made available for use or sale;
the intention to complete the intangible asset for use or sale;
 the availability of adequate technical, financial and other resources to complete the development and to use or sell it;
 an asset is created that can be separately identified for use or sale;
 it is probable that the asset created will generate future economic benefits; and
the development cost of the asset can be measured reliably.

Development work undertaken by the Group typically relates to the refinement of design, materials selection, construction techniques, 
firmware  and  control  systems  to  enhance  battery  system  performance  over  successive  generations.  Where  development  costs  are 
capitalised, they are amortised over the expected period to the introduction of the next generation of battery system. 

Amortisation is recorded over that period on a straight-line basis with the corresponding amortisation charge recognised in the statement 
of profit and loss as a component of administrative expenses.

Four years has historically been the typical cycle time between successive generations of battery system design.

Other intangible assets
Intangible assets other than goodwill that are acquired by the Group are stated at their historical cost of acquisition less accumulated 
amortisation and any impairment losses. 

Software and purchased domain names
Third-party software is initially capitalised at its cost of purchase. Amortisation is charged to administrative expenses over the expected 
useful life of the software which has been assessed as three years from the date of acquisition.

Acquired domain names are initially capitalised at cost of purchase. Amortisation is charged to administrative expenses over the expected 
useful life of the domain name which has been assessed as ten years from the date of acquisition.

Patents and certifications
Patent  rights  and  certifications  are  initially  capitalised  at  the  cost  of  applying  for  relevant  patent  rights  and  other  protections,  and 
certifications. Amortisation is charged to administrative expenses over the expected useful life of the patents and certifications which has 
been assessed as five years from the date of acquisition.

Property, plant and equipment
Items of property, plant and equipment are stated at historical cost less accumulated depreciation and any impairment losses. Historical 
cost includes expenditure that is directly attributable to the acquisition of the items. Subsequent expenditure is only included in the asset’s 
carrying amount or recognised as a separate asset, as appropriate, when it is probable that future economic benefits associated with that 
item will flow to the Group.

Costs that do not enhance the value of an asset such as repair and maintenance costs are charged to the statement of profit and loss 
in the period in which they are incurred.

Depreciation is charged to write off the cost of assets over their estimated useful lives on a straight-line basis. Depreciation commences 
on the date the assets are available for use. Work-in-progress assets are not depreciated until they are available for use and transferred 
to the appropriate category of property, plant and equipment.

Estimated useful lives for property, plant and equipment and other intangible assets are:

Depreciation methods, useful lives and residual values of assets are reviewed, and adjusted prospectively as appropriate, at each 
reporting date.

Where an asset is disposed of, the corresponding gain or loss on disposal is determined by comparing the sales proceeds received with 
the carrying amount of that asset at the date of disposal. Gains or losses on disposal of fixed assets are included within other items of 
operating income and expense in the statement of profit and loss.

Impairment of tangible and intangible assets 
The Group reviews the carrying values of its tangible and intangible assets, other than goodwill, at each balance sheet date to determine 
if any indicators exist that could mean those assets are impaired. Where an indicator of impairment exists the recoverable amount of the 
relevant asset (or CGU) is estimated to determine the amount of any potential impairment loss.

Recoverable amounts are determined using a discounted cash flow model related to each asset or CGU being assessed. The discount 
rate applied to the cash flows in the model is a pre-tax discount rate that reflects market assessment of the time value of money and risks 
specific to the groups of assets being considered.

If the recoverable value estimated in the cash flow model for a specific asset (or CGU) is lower than the carrying value, then the carrying 
value of the asset is reduced to its estimated recoverable value with a corresponding charge immediately recognised in the statement of 
profit and loss.

Where the condition that gave rise to an impairment loss reverses in a subsequent period, the impairment loss is similarly reversed and 
the carrying value of the asset increased to the revised estimate of its recoverable value. The carrying value of an asset immediately 
following the reversal of an impairment cannot exceed the carrying value that the asset would have had if the original impairment had not 
been made and the asset was depreciated as normal. A reversal of an impairment loss is recognised immediately in profit or loss.

continued for the year ended 31 December 2023

The value of any impairment (or reversal of impairment) of an asset is recorded in the same financial statement line item where depreciation 
or amortisation of the asset would normally be shown.

Where it is impractical to meaningfully assess recoverable amount using a discounted cash flow model, for instance where near term 
cash flows are low or negative, an assessment of the fair value adjusted for the costs that would be incurred in the disposal of an asset or 
operation is used. This is typically the case for development stage assets, operations or associated intangible assets (including goodwill) 
where the underlying products or technologies have not yet been commercialised.

Provisions
Provisions are established when the Group has a present legal or constructive obligation because of past events, it is probable that an 
outflow of resources will be required to settle the obligation and the amount of that outflow can be reliably estimated.

Provisions  are  measured  at  the  Group’s  best  estimate  of  the  expenditure  required  to  settle  the  obligation  at  the  financial  position  date, 
considering the risks and uncertainties of the obligation, and are discounted to present value of the expenditures that are expected to be 
incurred in settling the obligation using a pre-tax discount rate that reflects current market assessment of the time value of money and the risks 
related to the obligation. The initial recognition of a provision results in a corresponding charge to profit or loss. Where discounting is used, the 
carrying amount of a provision increases in each period to reflect the passage of time, this increase is recognised as borrowing cost.

Leases
Group entities only participate in lease contracts as the lessee. Lease contracts typically relate to facilities.

On inception of a contract, the Group assesses whether it contains a lease. A contract is a lease or contains a lease if it conveys the 
right to control the use of an identified asset for a period of time in exchange for consideration. The right to control the use of an identified 
asset is determined based on whether the Group has the right to obtain substantially all the economic benefits from the use of the asset 
throughout the period of use, and if the Group has the right to direct the use of the asset.

Obligations under a lease are recognised as a liability with a corresponding right-of-use asset, these are recognised at the commencement 
date of the lease.

The lease liability is initially measured at the present value of the lease payments that have not yet been paid at the inception of the lease, 
discounted using the interest rate implicit in the lease contract. Where the interest rate implicit in the lease contract cannot be readily 
determined, the Group’s incremental borrowing rate is used.

Variable lease payments that do not depend on an index or rate are not included in the measurement of the lease liability. The lease 
liability is measured at amortised cost using the effective interest rate method.

The lease liability is subsequently measured at amortised cost using the effective interest method. It is remeasured when: 

 there is a change in future lease payments arising from a change in an index or rate;
 there is a change in the Group’s estimate of the amount expected to be payable under a residual value guarantee; or 
 the Group changes its assessment of whether it will exercise a purchase, extension or termination option.

When a lease liability is remeasured under one of these scenarios, a corresponding adjustment is made to the carrying value of the right-
of-use asset or in profit and loss when the carrying amount of the asset has already been reduced to zero.

The corresponding right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability plus any lease 
payments made at or before the commencement date, any initial direct costs incurred and an estimate of the costs required to remove or 
restore the underlying asset, less any lease incentives received. The right-of-use asset is amortised over the shorter of the asset’s useful 
life and the lease term on a straight-line basis.

The Group has elected not to recognise right-of-use assets and corresponding lease liabilities for short-term leases, those existing leases 
with a lease term of less than 12 months and leases related to low value assets with an annual lease cost of £5,000 or less. The payments 
for the exempt leases are recognised as an expense on a straight-line basis over the lease term.

The  Group  has  elected  not  to  separate  non-lease  components  from  lease  components,  by  class  of  underlying  asset.  Each  lease 
component and any associated non-lease components are accounted for as a single lease component.

Inventory
Inventory is stated at the lower of cost and net realisable value. Cost comprises direct materials and, where applicable, direct labour costs 
and those overheads that have been incurred in bringing the inventories to their current location and condition. Cost is calculated using 
the first-in, first-out method.

Net realisable value is calculated as the estimated selling price for an item of inventory less estimated costs of completion.

Prepaid inventory
Prepaid inventory is recognised on inventory payments where physical delivery of that inventory has not yet been taken by the Group and 
is stated at the lower of cost and net realisable value.

Financial instruments
Financial  assets  and  liabilities  are  recognised  by  the  Group  and  recorded  in  the  statement  of  financial  position  when  the  Group  is 
contractually bound to the terms of the financial instrument. Financial assets and liabilities are derecognised when the Group is no longer 
bound by the terms of the financial instrument through settlement or expiry.

Financial assets
Financial assets are classified, at initial recognition, as subsequently measured at amortised cost, fair value through other comprehensive 
income (OCI), and fair value through profit or loss. 

The classification of financial assets to which the Group is a party is determined by the nature of the underlying financial instrument and 
the characteristics of the contractual cash flows expected to be received under the terms of instrument.

Financial assets are not reclassified after their initial recognition unless there is a contractual change in the nature of the cash flows under 
the instrument or the business purpose of the instrument has changed.

For a financial asset to be classified and measured at amortised cost or fair value through OCI, it needs to give rise to cash flows that are 
‘solely payments of principal and interest (SPPI)’ on the principal amount outstanding. This assessment is referred to as the SPPI test and 
is performed at an instrument level. Financial assets with cash flows that are not SPPI are classified and measured at fair value through 
profit or loss, irrespective of the business model.

Financial assets that the Group is party to are classified and measured as follows:

Financial asset 

Trade receivables 
Cash and cash equivalents 

Measurement basis

Amortised cost 
Amortised cost

Amortised cost 
On initial recognition, the Group measures amortised cost for financial assets based on the fair value of each financial asset together with 
any transaction costs that are directly attributable to the financial asset.

After  initial  recognition,  amortised  cost  is  measured  for  each  financial  asset  held  using  the  effective  interest  rate  method  less  any 
impairment loss identified. Interest income is recognised for all financial assets, other than those that are classified as short-term, by 
applying the effective interest rate for the instrument. Interest income on short-term financial assets is not considered to be material. Short-
term financial instruments are determined as those that have contractual terms of 12-months or less at inception.

Interest income, foreign exchange gains and losses, impairment, and any gain or loss on derecognition are recognised in profit or loss.

Impairment of financial assets
A loss allowance for financial assets is determined based on the lifetime expected credit losses for financial assets. Lifetime expected 
credit losses are estimated based on factors including the Group’s experience of collection, the number and value of delayed payments 
past the average credit periods across the Group’s financial assets. The Group will also consider factors such as changes in national or 
local economic conditions that correlate with default on receivables and financial difficulties being experienced by the counterparty.

Financial assets are impaired in full and a corresponding charge is recognised in profit or loss where there is no reasonable expectation 
of recovery.

Financial liabilities
The classification of financial liabilities is determined at initial recognition. Financial liabilities are classified and measured as follows:

Financial liability 

Trade and other payables 
Derivative Financial Instrument 
Lease liabilities 

Measurement basis

Amortised cost 
Fair value through Profit and Loss 
Amortised cost

Amortised cost
At  initial  recognition,  the  Group  measures  financial  liabilities  at  amortised  cost  using  the  fair  value  of  the  underlying  instrument  less 
transaction costs directly attributable to the acquisition of the financial liability.

Derecognition of financial liabilities
The  Group  derecognises  financial  liabilities  when  the  Group’s  obligations  under  the  relevant  instrument  are  discharged,  expired  or 
cancelled.

Derivative financial instruments
Derivatives are initially recognised at fair value on the date a derivative contract is entered into, and they are subsequently remeasured 
to their fair value at the end of each reporting period. Changes in the fair value of any derivative instrument are recognised immediately in 
profit or loss and are included in other gains/(losses).

Cash and cash equivalents
Cash and cash equivalents comprise cash in hand and on demand deposits, and other short-term highly liquid investments that are 
readily convertible to a known amount of cash and are subject to an insignificant risk of change in value.

Equity instruments
Instruments are classified as equity instruments if the substance of the relative contract arrangements evidences a residual interest in the 
assets of the Group after deducting all of its liabilities. Equity instruments issued by the Company are recorded as proceeds received, net 
of direct issue costs not charged to income.

Offsetting
Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statement of financial position if there 
is a currently enforceable legal right to offset the recognised amounts and there is an intention to settle on a net basis, to realise the assets 
and settle the liabilities simultaneously.

3 Critical accounting judgments and key sources of estimation uncertainty
The preparation of the financial statements in conformity with generally accepted accounting practice (GAAP) requires management to 
make estimates and judgments. Those estimates and judgments can affect the reported values for assets and liabilities as well as the 
disclosure of contingent assets and liabilities at the balance sheet date.

Management is also required to make estimates and judgments related to the reported amounts of revenues and expenses and related 
to the timing of the recognition of those revenues and expenses.

Judgments made and estimates applied are based on historical experience and other factors including management’s expectations 
of future events that are considered relevant. Actual results may differ from these estimates. The estimates, judgments and underlying 
assumptions made are reviewed on an ongoing basis and specifically in the preparation of the interim and annual published financial 
information.

Revisions to accounting estimates are recognised in the period in which the estimate is revised and applied consistently in future periods 
subject to the ongoing reassessment of estimates.

Invinity Energy Systems plc Annual Report and Financial Statements 2023 
 
 
 
Critical judgments for the year under review
Going concern
The Directors are required to assess whether it is appropriate to prepare the financial statements on a going concern basis. In making this 
assessment the Directors need to be satisfied that the Group can meet its obligations as they fall due and will remain cash-positive for a 
period of at least 12 months from the date of approval of the financial statements. Potential additional funding that is not yet committed at 
the date of approval of the financial statements cannot be anticipated in making the assessment of going concern.

The Directors make their assessment based on a cash flow model prepared by management and based on its expectation of cash flows 
for the 18-month period from the date of approval of the financial statements. The extended period in the model provides additional 
comfort that the 12-month solvency requirement can be met when making the assessment of going concern.

In preparing the cash flow model, assumptions have been made regarding the timing of cash collection from customers based on the 
expected cash receipt under contracts that require milestone payments to be made by customers. The timing of the receipt of milestone 
payments may not always align with or precede the costs incurred by the Company in performing its obligations under a contract.

Downside sensitivities have been applied to the cash flows primarily related to no sales being made. Refer to ‘Basis of preparation’ for 
details of the going concern analysis performed and the Directors’ conclusions regarding going concern.

The Directors expect that the business will continue to be viable throughout the model period and, accordingly, the financial statements 
have been prepared on a going concern basis.

Revenue recognition
Sales contracts are assessed in accordance with the Group accounting policy for revenue recognition. The policy requires the identification 
of the performance obligations, or promises, under the contract and a determination of the conditions and implications of each performance 
obligation. Revenue is recognised only when a distinct and appropriate performance obligation under a contract is satisfied.

Some  performance  obligations  are  satisfied  separately  such  as  the  delivery  of  the  battery  systems  and  integration  hardware.  Other 
obligations may be satisfied in conjunction with other contract promises or where a contract calls for equipment sold under the contract to 
be integrated into a larger project before formal acceptance is notified by the customer.

Where the ability of a customer to benefit from a product or service is dependent on the satisfaction of other performance obligations, 
more than one promise may need to be bundled together as a combined performance obligation that must be satisfied before the revenue 
related to each element can be recognised.

Identifying where hardware or services are readily available from other providers is a key determinant as to whether a contract promise represents 
a separate performance obligation or if it should be bundled with other promises that, together, represent a single performance obligation.

Sources of estimation uncertainty for the year under review
Warranty provision
The Company provides time-limited standard warranties in its contracts for sale of battery systems. In addition, customers may elect to 
purchase separate, standalone extended warranties. Extended warranties are for periods greater than the standard warranties that are 
provided with the purchase of all battery systems.

Estimating the costs that may be incurred by the Company in servicing warranty agreements requires management to estimate the number 
of expected claims in relation to the total number of battery systems sold. In addition, an estimate of costs that the Company could expect to 
incur to remedy each warranty claim should also be made to determine the amount of the total provision that should be recorded for warranties.

Provisions made in respect of expected warranty obligations are reassessed and remeasured where actual experience indicates the 
claim rate may be higher or lower than initially expected or where costs to remedy warranty claims differ from the assumptions used in 
calculating the provision. The release of an over-provision of warranty costs results in other operating income being recognised in the 
period whereas an additional provision for warranties results in a charge being recognised.

A 20% increase in the number of warranty claims or a 20% increase in the cost to remedy warranty issues would increase the provision 
by £120,436. A 40% increase in the number of warranty claims or a 40% increase in the cost to remedy warranty issues would increase 
the provision by £240,872.

Refer to note 21, contract related balances.

UK  /  U.S.  /  CANADA  /  AUSTRALIAFINANCIAL STATEMENTSAnnual Report and Financial Statements 2023Notes to the Consolidated Financial Statements 
continued for the year ended 31 December 2023

Provision for onerous contracts
A contract is onerous when the unavoidable costs of meeting the Company’s obligations under the contract are expected to be greater 
than the revenue earned under that contract. 

The assessment of unavoidable costs includes direct costs such as parts and labour and indirect costs, such as production overhead or 
indirect labour, that are expected to be incurred in servicing a warranty claim.

The assessment of future costs is inherently subjective and requires the use of estimates in determining the appropriate amount of 
provision that may be required.

A 20% increase in unavoidable costs would increase the provision by £66,493. A 40% increase in unavoidable costs would increase the 
provision by £132,986. 

Refer to note 21, contract related balances.

Notes to the Consolidated Financial Statements 
continued for the year ended 31 December 2023

A total of 39,956 employee options were exercised during the year (2022: 87,678) with a weighted average exercise price of 14.64 pence 
per share (2022: 4.34p).

The grant-date fair value of share options issued is calculated using a Black-Scholes methodology at the date of grant. Key inputs to 
the model include the share price at the date of grant, the option exercise price, the term of the award, share price volatility, the risk-free 
interest rate (by reference to government bond yields) and the expected dividend yield rate, which has historically been and continues to 
be zero, reflective of the development-stage nature of the Group.

The Long-term Incentive Plan, Camco 2006 Executive Share Plan and redT 2015 Plan are closed and all options have expired in 2023. 
No further option awards will be made under any of these plans.

The aggregate number of options granted, vested, exercised and forfeited during the year under the plans are summarised and analysed 
between unvested and vested awards as follows:

Plans with standard performance conditions
The primary share plan that remains outstanding at 31 December 2023 is the 2018 plan. The 2018 plan was adopted by the Board on 14 
May 2018 and introduced HMRC scheme rules related to certain non-taxable option grants. The plan contains a provision to issue options 
as CSOP, EMI or unapproved awards.

Parallel options issued
In addition, certain legacy redT options were reissued in 2020 as they were considered by the Board to be sufficiently ‘out-of-the-money’ 
such that they no longer provided a performance incentive to the holders of the options. As a mechanism to adjust the terms of the 
unfavourable options, new parallel options were issued on a one-for-one basis with the same terms as the original awards excepting that 
they were issued with a lower exercise price.

Both the original and parallel option schemes remain in existence. However, the exercise by an employee of a single option from either 
pool (original or parallel) allocated to them will cause the equivalent value in the other pool to be forfeited. Accordingly, the number of 
options disclosed above has been adjusted to remove the number of options that is equivalent to the number of parallel options issued.

Other options
On 10 May 2021, the Company granted an option for 8,672,273 shares to Gamesa Electric S.A. Unipersonal (GaE), a wholly-owned 
subsidiary of Siemens Gamesa Renewable Energy S.A. The options were granted to GaE in consideration of its entering into a joint 
development and commercialisation agreement with Invinity Energy Nexus Limited, a wholly-owned subsidiary of the Company. 

The exercise price of the options is 175 pence and upon exercise of those options then for as long as GaE holds at least 5% of the issued 
share capital of the Company it shall be entitled, subject to certain conditions, to nominate one non-executive director to the Board of the 
Company. The options expire on 10 May 2025.

Warrants issued in the period or outstanding
The Company had 909,090 warrants outstanding at 31 December 2023 in relation to a 2020 investment agreement with Riverfort Global 
Opportunities (“Riverfort”) which expired 2 April 2024. 

VSA Capital was awarded 340,000 warrants with an exercise price of 82.5 pence in April 2020, at the time of the merger. These warrants 
are outstanding and expire on 2 April 2025. In June 2023, the exercise price was amended to 50 pence with the expiry date remaining 
unchanged. 

In December 2021, the Company issued 14,464,571 ‘placing units’ comprised of one share, one short-term warrant and one long-term 
warrant.

At  31  December  2023,  the  Company  had  nil  (2022:  14,464,317)  short-term  warrants  and  14,463,665  (2022:  14,646,317)  long-term 
warrants outstanding. 

Short-term warrants expired 16 December 2023. The long-term warrants’ subscription price was amended to 100 pence per ordinary 
share, giving the holder the right to subscribe to one new ordinary share at any time from Second Admission until 16 December 2024. 
The warrants are trading on the Aquis Stock Exchange (AQSE) and have been deemed to have no fair value based on the price at which 
they are currently quoted. 

In December 2022, the Company issued 1,350,020 warrants as part of the convertible loan facility with Riverfort Global Opportunities and 
YA II PN Ltd (“Noteholders”). Each warrant gives the holder the right to subscribe for one new ordinary share at a price of 32 pence per 
ordinary share until 14 December 2026.

In consideration of the Noteholders undertakings, the Company has agreed to grant a further 449,980 warrants at an exercise price of 32 
pence which will expire on 14 December 2026.

Additional potential shares used in the calculation of diluted earnings per share primarily relate to potential shares outstanding at 31 
December 2023 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.

For impairment testing goodwill acquired through business combinations and patents and certifications with indefinite useful lives are 
allocated to the single CGU.

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 
and the discounted cash flow forecasts used to estimate the recoverable amounts. The discount rate used in the calculation amounted 
to 15%. Change of discount rate by 5% would not result in impairment of goodwill given significant headroom was maintained under all 
sensitivity scenarios run. No impairment loss was identified in relation to goodwill. 

On 24 May 2024, the Company announced the results of a placing, subscription and open offer. The fundraising raised total proceeds of 
£57.38 million through placing of 121,739,130 new ordinary shares, subscription of 121,739,130 new ordinary shares and open offer of 
6,011,983 new ordinary shares at 23.0 pence per share. 

The  closing  share  price  on  30  May  2024  was  22.00  pence,  giving  a  market  capitalisation  of  £42.0  million  which  does  not  indicate 
impairment of goodwill or net assets.

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 
31 December 2023.

1   During the year, adjustments were made to remove variable payments related to non-lease components from the lease liability and right-of use assets.  

2   During the year, right-of-use assets were transferred to property, plant and equipment upon completion of lease terms.

Right-of-use assets relate to buildings, vehicles and equipment held under leases with third-party lessors. A right-of-use asset represents 
the Company’s right to use a leased asset over the term of the lease. The Company’s rights to use specific buildings, items of equipment 
or specific vehicles under lease arrangements represent assets to the Group.

The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be readily determined, which is generally 
the case for leases in the Group, the lessee’s incremental borrowing rate is used, being the rate that the individual lessee would have 
to pay to borrow the funds necessary to obtain an asset of similar value to the right-of-use asset in a similar economic environment with 
similar terms, security and conditions.

To determine the incremental borrowing rate, the Group: 

 where possible, uses recent third-party financing received by the individual lessee as a starting point, adjusted to reflect changes in 
financing conditions since third party financing was received;
 uses a build-up approach that starts with a risk-free interest rate adjusted for credit risk for leases held by the Group, which does not 
have recent third-party financing; and
 makes adjustments specific to the lease, e.g. term, country, currency and security.

Group had the following tax losses carried forward available for use in future periods:

Under current tax legislation tax losses in the United Kingdom and Ireland can be carried forward indefinitely and be offset against future 
profits arising from the same activities at the tax rate prevailing at that time. There is a portion of the tax losses in the United States of 
America that will begin to expire in 2035, whereas the majority can be carried forward indefinitely. The tax losses in Canada can be carried 
forward 20 years and will begin to expire in 2035.

Due  to  the  uncertainty  regarding  the  timing  and  extent  of  future  profits  within  these  subsidiaries,  no  deferred  tax  assets  have  been 
recognised in respect of these tax losses. Deferred tax is also not recognised on the timing differences between accounting and tax 
treatment in these subsidiaries given the offsetting tax losses on which no deferred tax has been recognised.

The UK Government announced that the Corporation Tax rate increased from 19% to 25% on profits of over £250,000, effective 1 April 
2023. Profits below £50,000 continue to be chargeable to Corporation Tax at 19%. In computing the UK deferred tax asset, management 
has assumed that as neither the deferred tax assets nor the deferred tax liabilities will crystallise in the immediate future, calculations based 
on 19% are appropriate.

(6,138)

The amount of revenue recognised in the year that was included in contract liabilities at the end of the prior year was £8,097,770 (2022: 
£428,417).

The aggregate position on customer contracts included in the statement of financial position will change according to the number and 
size of contracts in progress at a given year-end as well as the status of payment milestones made by customers toward servicing those 
contracts. The Group structures payment milestones in its customer contracts to cover upfront expenditure for parts and materials and 
other working capital requirements associated with the delivery of promises under customer contracts to better manage Group cash flow.

The timing of revenue recognition is based on the satisfaction of individual performance obligations within a contract and is not based on 
the timing of advances received. Customer advances are recognised as contract liabilities in the statement of financial position and are 
released to income progressively as individual performance obligations are met. The difference in timing between the receipt of contract 
advances and the timing of the satisfaction of performance obligations for revenue recognition can cause values to remain in deferred 
income. The amount of such deferrals is related to both the overall size of the underlying contract and the planned pace of delivery in the 
related work schedule. This is expected to occur where satisfaction of performance obligations is evidenced by customer acceptance of 
the good or service that is the subject of the performance obligation.

Warranty provision
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 provided to all 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 legacy products
Where it is considered of commercial value, management has elected to provide for the costs of ongoing maintenance for certain legacy 
products. Provisions in respect of legacy products have fully unwound in 2023 and are no longer provided.

Provision for contract losses
A provision is established for contract losses when it becomes known that a customer 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.

In determining the amount to be provided, management has evaluated the likelihood of input costs continuing to rise against a backdrop of 
inflation and instability due to current macro-economic factors such as, the increasing price of oil feeding through to production and shipping 
costs and continuing supply chain issues.

Provisions in respect of contract losses relate to contracts which are expected to be delivered in 2024 and will therefore unwind during 
that year. Provisions in respect of contract losses relating to extended warranties for up to a total of ten years will unwind over that period.

All trade receivables relate to receivables arising from contracts with customers.

Trade 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.

The actual credit loss over 2023 was determined to be less than 1% of total sales (2022: less than 1%). An allowance for potential credit 
losses of £139,639 (2022: £23,953) has been recognised.

Investment funding arrangement 
On 14 December 2022, the Company entered into an investment agreement with Riverfort Global Opportunities PCC Limited and YA 
II  PN  Ltd.  (“Noteholders”).  The  instrument  was  entered  by  way  of  an  initial  drawdown  in  the  amount  of  US$2.5  million  and  related 
subscription of 2,870,038 shares priced at nominal value of €0.01 and to be used to facilitate the conversion of amounts advanced under 
the investment agreement.

Pursuant to the facility, the Noteholders were granted warrants exercisable at 67.35p to subscribe for 1,350,020 ordinary shares for a 
period of up to four years. These warrants remain outstanding and have been repriced to 32p being the price per share achieved in the 
2023 capital raise. In consideration of the Noteholders undertakings, the Company has agreed to grant a further 449,980 warrants at an 
exercise price of 32p which will expire on 14 December 2026.

Company’s option and carried a redemption premium of 10% paid to the Noteholders at the date of prepayment totalling US$208,107.

Following the redemption of the investment agreement, proceeds from the sale of the conversion shares were split 97% to the company 
and 3% to the Noteholders, resulting in net proceeds to the Company of £742,601.

During the year, 72,059,618 new shares were issued with a nominal value of £631,857. The total gross proceeds were £23,045,832 
with the balance of £22,413,975 credited to the share premium account. Total costs of issuance were £1,117,307 and these costs were 
charged directly to the share premium account.

On 22 November 2022, the Company subdivided each ordinary share of €0.50 nominal value into one ordinary share of €0.01 each and 
one Deferred A Share of €0.49 each. The Deferred A Shares do not have any voting rights and are not admitted to trading on AIM or any 
other market. They carry only a priority right to participate in any return of capital or in any dividend to the extent of €1 in aggregate over 
the class. The Deferred A Shares are, for all practical purposes, valueless and it is the Board’s intention, at an appropriate time, to have 
the Deferred A Shares cancelled in accordance with Companies Law. 

Ordinary shares have a par value of €0.01. The holders of ordinary shares are entitled to receive dividends as may be declared from time

Invinity Energy Systems plc Annual Report and Financial Statements 2023 
 
28 Financial assets and liabilities
All financial assets are held at amortised cost. There were no financial assets measured at fair value through other comprehensive 
income nor through profit and loss in either period presented.

The maximum exposure to credit risk at the end of the reporting period is the carrying amount of each class of financial asset presented 
above. The carrying value of the financial assets approximate their fair values due to the short-term maturities of these instruments.

The Group does not currently use derivative instruments for managing financial risk. All financial liabilities are held at amortised cost.

Recognised fair value measurements
The Group uses the following hierarchy for determining and disclosing the fair value of financial instruments by valuation technique:

Level 1:  

 The fair value of financial instruments traded in active markets (such as publicly traded derivatives, and trading securities) 
is based on quoted market prices at the end of the reporting period.

 The battery systems manufactured by the Company use vanadium metal as a key component in the electrolyte. Vanadium 
is an actively traded commodity for which quoted market prices are available.

 The Company does not currently hold inventories of vanadium. Vanadium purchased from third parties is solely for the use 
in electrolyte and open purchase contracts are not accounted for as derivatives.

Level 2: 

 The fair value of financial instruments that are not traded in an active market (for example, over-the-counter derivatives) is 
determined using valuation techniques that maximise the use of observable market data and rely as little as possible on 
entity-specific estimates. If all significant inputs required to fair value instrument are observable, the instrument is included 
in Level 2. 

 At 31 December 2023, the Company held warrants issued to Riverfort Global Opportunities and YA II PN Ltd as part of the 
December 2022 financing event. The warrants are valued using Level 2 inputs as they do not represent a fixed-for-fixed 
equity instrument and are valued using observable market factors such as the share price at the date of the grant, the term 
of the award, the share price volatility and the risk-free interest rate.

Level 3: 

If one or more of the significant inputs is not based on observable market data the instrument is included in Level 3. 

 The  Group  did  not  hold  any  financial  assets  or  liabilities  that  were  required  to  be  valued  using  Level  3  inputs  at  31 
December 2023 (2022: none). 

 No other financial instruments were outstanding at the period end that required to be valued using a methodology that 
uses Level 1, 2 or 3 inputs.

Market risk – foreign exchange risk
The Group is primarily exposed to foreign exchange risk related to bank deposits, receivables or payables balances and other monetary 
working capital items that are denominated in a currency other than the Company’s functional currency which has been determined to 
be GBP.

The Group does not speculate on foreign exchange and aims to mitigate its overall foreign exchange risk by holding currency in line 
with forecast regional operating expenses, providing an element of natural hedge against adverse foreign exchange movement.

Sensitivity – exchange rates
The sensitivity of profit or loss to changes in quoted exchange rates for currencies to which the Group is exposed is as follows, based on 
each relevant exchange rate strengthening (or weakening) by 5%.

There is no impact on other components of equity as the Group is not party to any derivative financial instruments, such as hedging 
instruments, where currency gains and losses would be recognised in other comprehensive loss.

Market risk – commodity price risk
The Group’s batteries use an electrolyte incorporating vanadium. Vanadium is an elemental metal and is used primarily to strengthen 
steel, particularly for the construction industry.

Whilst it is not a mature market traded commodity, such that one can buy forward or derivative contracts, market prices for vanadium 
pentoxide (V2O5) at 98% purity are quoted in US dollars per pound. 

Vanadium forms about two-thirds of the value of the electrolyte, which in turn forms about a quarter of the landed cost of a battery, and so 
a fluctuation in the price of vanadium will impact the profitability of battery sales. An increase or decrease in the market price of vanadium 
of 5% could cause the value of the electrolyte component of a battery to increase or decrease by approximately 3%.

Credit risk – cash held on deposit with banks
Credit risk arises from cash and cash equivalents and deposits with banks and other financial institutions.

Credit risk related to holdings with financial institutions is managed by only maintaining bank accounts with reputable financial institutions. 
The Group aims only to place funds on deposit with institutions with a minimum credit rating of B2 Moody’s.

The Group’s cash at bank and short-term deposits are held with institutions with credit ratings as follows:

Credit risk – trade and other receivables
Past due but not impaired
The Group’s credit risk from receivables encompasses the default risk of its customers and other counterparties. Its exposure to credit 
risk is influenced mainly by the individual characteristics of each customer or counterparty. The creditworthiness of potential and existing 
customers is assessed prior to entering each new transaction. A credit analysis is performed, and appropriate payment terms implemented 
that may include increased level of upfront deposits for the purchase of battery units. The Group’s standard terms of trade provide that up 
to 90% of the sales price of a battery unit is paid prior to delivery. 

Receivables are considered for impairment on a case-by-case basis when they are past due or where there is objective evidence that the 
customer or counter party may be a default risk. The Group takes into consideration the customer or counter party payment history, its 
credit worthiness together with the prevailing economic environment in which it operates to assess the potential impairment of receivables. 
The assessment reflects the probability-weighted outcome, the time value of money and reasonable and supportable information that is 
available at the reporting date about past events, current conditions and forecasts of future economic conditions.

On an ongoing basis, receivable balances attributable to each customer or other counterparty are monitored and appropriate action 
is taken when the relevant balance becomes or is considered likely to become overdue. The maximum exposure to loss arising from 
receivables is equal to invoiced value.

The ageing of trade receivable balances was:

Liquidity risk
Liquidity risk relates to the Group’s ability to meet its obligations as they fall due. 

The Group generates cash from its operations that are principally related to the manufacture and installation of vanadium flow batteries. 
The  market  for  reliable  and  flexible  grid-scale  storage  solutions  for  energy  generated  from  renewable  sources  is  growing  and  the 
technology continues to develop.

The development of new and enhanced storage technologies can be capital intensive and the Group has historically funded development 
and early-stage commercial activity primarily from equity investment but also using cash from operations and loan funding.

The Group forecasts cash generation using a comprehensive company financial model and monitors the timing and amount of its payment 
obligations.

The following table shows the Group’s financial liabilities by relevant maturity grouping based on contractual maturities. The amounts 
included in the analysis are contractual, undiscounted cashflows.

Invinity Energy Systems plc Annual Report and Financial Statements 202332 Contingent liability 
The Group is involved in legal proceeding with a landlord with a received claim which has a possible range from £nil to £693k. While the 
outcome of this matter is uncertain and difficult to predict, management believes that, based on the information currently available, the 
ultimate resolution of these matters will not have a material adverse effect on the Group’s financial position.

33 Events occurring after the report period
On 26 February 2024, the Company announced that it had entered into an agreement with its Taiwanese strategic partner, Everdura, 
to undertake domestic manufacturing of its next generation vanadium flow battery (“VFB”) product, code-named “Mistral”, to serve the 
Taiwanese and other markets (“the Agreement”). Under the Agreement, Everdura will manufacture Mistral VFBs to fulfil orders it intends 
to secure under the terms of the existing reseller agreement which targets more than 255 MWh of product sales over a three-year period. 
The Agreement states that Everdura will pay Invinity a royalty fee based on a material percentage of the sale price of any Mistral products 
sold. Everdura will also utilise Invinity’s existing supply chain and purchase cell stacks directly from the Company, which will continue to 
be manufactured by Invinity at its facilities in the UK and Canada.

In addition, on 24 May 2024, the Company announced it had raised gross proceeds of £57.4 million through the issue of 249,490,243 new 
ordinary shares of €0.01 each at the issue price of 23 pence per new ordinary share. Of this amount, £25.0 million was raised through a 
subscription by the UK Infrastructure Bank (the British state-owned policy bank), £3.0 million by Korean Investment Partners (an affiliate 
of Korea Investment Holdings, a leading financial conglomerate in the Republic of Korea) acting through an investment fund, £28.0 million 
through an oversubscribed placing with institutional and other investors and £1.38 million from an open offer of 3 open offer shares for 
every 20 ordinary shares held to existing shareholders. 

The fundraising shares were admitted to trading on the AIM market of the London Stock Exchange and the APEX segment of the AQSE 
Growth Market on 24 May 2024.
