A COMPANY AND AN INDUSTRY RACE FORWARD

By Matt Harper, Chief Commercial Officer

Last year I talked about how Invinity was at a critical threshold where 
the three pillars of value, cost and proof – value to our customers, 
cost of delivering that value, and proof that we and our products 
can  deliver  –  were  the  foundation  for  significantly  growing  our 
commercial opportunities. Since that time we were able to solidify 
those pillars, and I’m thrilled that doing so massively accelerated 
the commercial acceptance of our product. 

THE THREE PILLARS
We and our customers now have data that shows the value our 
pioneering projects are delivering; going above and beyond traditional 
lithium-ion systems to deliver multiple value streams in parallel. At the 
Energy Superhub Oxford, for instance, our 5 MWh battery has been 
operating in wholesale electricity markets and performing ancillary 
services since the summer of 2022, proving the range of capabilities  

our  products  provide  for  customers.  Similarly  at  Scottish  Water 
Perth, our battery is increasing the on-site use of self-generated, 
low carbon electricity while also saving the site operator money by 
decreasing the amount of electricity they purchase when electricity 
tariffs are at their peak.

“ Our batteries can 
revolutionise energy 
storage applications  
the world over in 2023”

Matt Harper
ChiefCommercialOfficer

But even the most valuable assets need to be purchased and financed 
– so  cost matters, and Invinity made significant advancements in 
2022.  Product  design  simplifications,  new  supply  chain  partners 
and new, more streamlined facilities have decreased our production 
costs, allowing us to sell at prices that contribute to our bottom line 
while keeping customer business cases resoundingly positive. We 
have also worked to further decrease the costs our customers incur 
to operate and maintain our products over a service life measured 
in  decades  rather  than  years,  truly  maximizing  their  return  on 
investment. And perhaps most importantly, the focus on full lifecycle 
cost  reduction  has  set  the  stage  for  our  next  generation  product, 
code-named  “Mistral”,  whose  fundamentally  simpler,  lower-cost 
design will allow us to compete directly with the most aggressively 
priced energy storage systems on the market.

Finally, when we think about proof, we have made significant leaps 
in giving new partners – be they customers, financiers, resellers or 
regulators – confidence that our batteries are the right solution for 
solving the toughest problems on the electric grid. Not only have 
we implemented data analytics and reporting tools that show our 
existing  customers  how  our  products  are  befitting  them  both  in 

real-time and in aggregate, but we have developed assets such as 
a bankability report from global assurance and risk management 
leader DNV to prove how Invinity’s vanadium flow batteries deliver 
as expected.

FROM A STRONG FOUNDATION
And  it  worked.  Invinity  saw  tremendous  commercial  success 
through  the  latter  half  of  2022  building  directly  on  these  pillars, 
contracting for more business in that period than in the history of 
the Company to date. Excitingly this included projects that are in 
potentially  massive  new  segments  like  data  centres  (with  Kinetic 
Solutions in Arizona); that present a first engagement with regional 
partners who plan to revamp entire national electricity grids (with 
Hyosung in South Korea, Everdura in Taiwan and, more recently, 
both Equans and STS in Europe); and that will demonstrate how at 
any scale our batteries, combined with renewables, can decrease 
costs  and  accelerate  decarbonization  for  major  electricity  users 
(with  Indian  Energy  in  Southern  California).  With  each  of  these 
projects  progressing  towards  delivery,  we  are  looking  forward  to 
further proving how our batteries can revolutionise energy storage 
applications the world over in 2023.

over 35 MWh across four continents, embodying almost 
1000 individual flow batteries”

FROM ONE TO MANY
The  above-stated  developments  are  impressive,  and  I  am 
energized  every  day  by  being  part  of  a  team  that  continues  to 
deliver  commercial  success  year  after  year.  Beyond  Invinity’s 
walls, though, those same three pillars of value, cost and proof 
are  beginning  to  deliver  huge  leaps  forward  for  grid-connected 
energy storage in general. In the last year, industry associations 
like  the  Long  Duration  Energy  Storage  Council  have  worked 
to  advance  a  consensus  view  of  how  longer  duration  storage, 
especially  incorporating  non-lithium  technologies,  can  create 
enormous value while unlocking a renewables-fueled global path 
to  net  zero.  Across  the  nascent  long  duration  energy  storage 
(“LDES”)  industry  costs  are  decreasing  and  supply  chains  are 
normalizing; by contrast, the growing EV market is driving costs 
up and availability down for lithium-ion batteries, broadening the 
opportunity for competition. 

And the proof? One only needs to look to the funding governments 
and  regulators  are  putting  into  our  industry,  from  the  California 
Energy Commission (or CEC)’s US$380m for non-lithium LDES 
to the UK Department of Energy Security and Net Zero (DESNZ)’s 
£69m  for  Longer  Duration  Energy  Storage  (LODES)  solutions 
for  the  UK  grid.  We  are  delighted  to  see  broad  support  for  our 
sector and especially thrilled that, in both cases, Invinity is at the 
forefront, with the CEC and DESNZ providing financial support to 
our Viejas Resort and Casino project in California and our Phase 
2 LODES competition project in the UK, respectively. Additionally, 
the  U.S.  Department  of  Energy  has  recently  published  a  report 
titled  “Pathways  to  Commercial  Liftoff:  Long  Duration  Energy 
Storage”, which projects that the intra-day LDES market, on which 
Invinity is focused, is expected to be as large as 274 GW in the 
U.S.  alone  by  2050.  These  and  other  agencies  the  world  over 
are convinced long duration storage is critical to a net zero grid; 
their support of Invinity to date proves they see us as leaders in 
delivering that vision.

In  2023  Invinity  will  build  on  this  momentum.  First,  we  expect 
to  deliver  a  fleet  of  flow  batteries  totaling  over  35  MWh  across 
four continents, embodying almost 1000 individual flow batteries. 
That’s not just a commercial success; it will give us operational 
experience,  applications  expertise  and  an  unparalleled  dataset 
from  which  to  draw  the  customer,  technical  and  data-driven 
insights that will accelerate our progress and advance our market-
leading position.

Perhaps most exciting though are our plans to initiate on our first 
projects this year for our next-generation battery, Mistral. This isn’t 
just about developing a cheaper, higher-performance battery; we 
expect Mistral will define a new category of high-throughput grid-
connected energy storage. A major trend in renewables over the 
last  five  years  has  been  the  combination  of  solar  photovoltaic 
generation with storage as the dominant paradigm for utility-scale 
plants. By contrast, maximising intermittent wind output with fast-
responding,  durable  battery  storage  is  a  much  more  demanding 
service, requiring intervention by the second, by the hour and over 
days. The economics of delivering that level of throughput over the 
decades-long  service  life  of  a  wind  farm  by  lithium-ion  batteries 
simply do not add up.

Mistral, whose development draws from deep expertise from the 
wind  industry,  will  be  the  first  product  designed  from  the  ground 
up  to  maximise  the  benefits  storage  can  deliver  to  renewable 
generation. This matters because in the UK, wind dominates over 
solar; but even with recent increases in the cost of gas generation 
driven by geopolitical uncertainty, wind power’s intermittency has 
limited its ability to substitute for gas as prices rise. Mistral will close 
that gap, delivering energy on demand from wind and helping to 
stabilize UK energy prices with low-cost, low-carbon, domestically-
produced power.

No  matter  what  proportion  of  the  global  energy  storage  market 
Invinity is able to capture – and we think we are ideally positioned 
to capture a large slice of the pie – it is unequivocal that this is a 
revolutionary opportunity of the kind that comes about only once in 
a  generation.  The  last  two  decades  have  proven  that  renewables 
are an inexpensive, effective source of clean energy for the electric 
grid; the next two will prove that energy storage can turn that energy 
into on-demand, low-cost power our homes, our industry, and our 
institutions  in  a  net  zero  future.  The  year  ahead  will  see  Invinity 
continue to accelerate our part in making that future a reality.

BREAKING NEW GROUND

Chairman’s Report 

I  am  delighted  to  report  to  shareholders  that  Invinity  has 
accelerated  its  deployment  of  working  assets  and  built  up 
a significant order book for delivery in 2023 and 2024. We are 
focused on deploying and operating the units that have been 
shipped,  winning  new  contracts  and  developing  the  next 
generation of our vanadium flow battery which we believe will 
play a significant role in Invinity’s rapid progression through the 
current loss-making phase towards becoming a self-sustaining, 
profitable  business.  It  is  worth  restating  why  we  see  Invinity 
winning a significant market share in the global energy storage 
market.  Invinity  has  created  a  modular,  long-duration  battery 
with  a  20+  year  asset  life,  capable  of  achieving  some  of  the 
lowest possible levelised cost of storage metrics. This means our 
technology  is  an  ideal  solution  for  both  commercial  and  utility-
scale  customers  wishing  to  reduce  their  energy  costs,  utilise 
greater  amounts  of  renewable  energy  and  accelerate  progress 
towards net zero. Given the world’s urgent focus across these key 
areas, this opens up a potentially huge addressable global market 
for Invinity, who are uniquely positioned with a mature, production-
ready product which has already been proven in the field. 

2022 saw record global deployment of energy storage, particularly in 
the U.S. and the UK, and I am pleased to note Invinity’s own contribution 
to this trend. We sold a record number of vanadium flow batteries 
during  the  period  to  customers  in  both  new  and  existing  markets, 
making this our best commercial year to date, and underscoring my 
belief  that  the  Company  has  reached  a  key  milestone  in  terms  of 
commercial acceptance. One of the key drivers of this success was 
potential customers being able to see our batteries in operation at 
key sites and I was proud to represent Invinity at the launch of our 5 
MWh vanadium flow battery, the UK’s largest operational VFB, at the 
Energy Superhub Oxford in July 2022. Projects such as this attract 
worldwide attention and have helped to place Invinity at the forefront 
of many developers’ minds.

Delivery is an important target for Invinity. Signing contracts is the first 
step of the commercial process, but the follow through to delivery and 
handover generates revenue and ultimately long-term value for our 
shareholders. Having operational systems in the field is an important 
indicator of the significant progress the Company has made in this 
regard, but as a manufacturer of ‘emerging’ battery technology, at 
the core of our business will always be our ability to build and deliver 
our products effectively. Notably, the expansion of our manufacturing 
capabilities  has  set  us  on  the  path  towards  delivering  even  larger 
projects, faster and more economically than ever before. 

During 2022 the team successfully deployed funds that were raised 
in late 2021 to support our operational and commercial growth and 
I’m greatly encouraged to report demonstrable progress in both areas 
during  the  period.  The  funds  raised  at  the  beginning  of  2023  are 
already supporting the next steps of our growth as we progress from 
a revenue-generating to a profit-generating business. The work we 
have done means I remain confident that Invinity is now even better 
positioned  to  take  advantage  of  this  buoyant  market  evidenced  by 
our  well-developed  commercial  pipeline,  which  now  includes  a  first 
look at the over 1 GWh of qualified commercial interest for our next-
generation vanadium flow battery and confirms Invinity’s place as one 
of the global market leaders for vanadium flow battery technology.

Non-ExecutiveChairman

My  Board  and  I  have  ensured  Invinity  continues  to  follow  a 
clear  and  well-developed  strategy,  set  out  in  detail  later  in  this 
report.  Invinity’s  core  markets  remain  the  UK,  North  America 
and  Australia  and  we  maintain  our  belief  that  these  are  the 
most  appropriate  areas  for  focus  given  the  Company’s  current 
capabilities. However, new markets are also emerging in Europe 
and Asia and the formation of key partnerships that enable us to 
expand our reach commercially and operationally without the need 
for a full corporate presence and the associated overhead costs is 
another important strategic decision that has been made. 

To  this  end,  I  am  pleased  to  note  we  have  signed  three  new 
reseller partnerships in 2022 that enable us to access some of the 
fastest growing markets in the world, such as Korea and Taiwan. 
Encouragingly,  this  momentum  has  continued  into  2023  with 
entry into new European markets and further important business 
relationships initiated in our core UK and U.S. markets. The hard 
work carried out by our team in establishing and supporting these 
strategic  relationships  is  already  bearing  fruit  with  our  largest 
sale  of  2022  being  a  15  MWh  deal  with  our  Taiwanese  partner 
Everdura.

Looking  inward,  the  Invinity  team  is  operating  strongly,  winning 
new contracts, deploying our batteries and continuing to develop 
our leading-edge technology. I would like to take this opportunity to 
thank the entire team for their hard work and perseverance during 
2022  and  the  current  year  to  date.  I  would  also  like  to  thank  all 
my  Board  colleagues  for  their  support  and  assistance  over  the 
year,  particularly  to  Jonathan  Marren  who,  stepping  back  into 
an Executive role, is already making a significant impact on the 
strategic and financial side of the business.

In  summary,  2022  can  be  marked  as  a  key  inflection  point  in 
Invinity’s  progress,  with  almost  40  MWh  of  sales  signed,  a  
£23.7m  sales  orderbook  for  delivery  across  2023,  our  largest 
project to date launched and operational and a growing partnership 
network  that  is  already  bringing  commercial  benefits  to  the 
Company. An improved corporate and operational structure has 
set us up well for the future and 2023 is already shaping up to be 
another transformational year, supported by the successful March 
fundraise and continued commercial progress. 

I  remain  extremely  optimistic  in  the  outlook  for  Invinity.  I  am 
extremely  grateful  for  the  continued  support  from  you,  our 
shareholders,  without  which  we  would  not  be  in  our  strongest 
position yet to take this next step on our journey.

Chief Executive Officer’s Report 

Larry Zulch
ChiefExecutiveOfficer

Efforts from years past bore fruit in 2022. We closed deals for 
more energy storage than we had closed in our entire previous 
history.  As  expected,  we  reported  a  loss  for  2022,  but  were 
able  to  transition  from  closing  loss-making  deals  to  signing 
ones that are anticipated to yield positive gross margins. I’m 
pleased  to  report  that  all  but  one  of  the  contracts  closed  in 
2022 is forecast to achieve this requirement. We manufactured 
more  product  than  in  any  previous  year,  progressed  our 
next  generation  product  and  established  significant  new 
partnerships. Perhaps most importantly, we set the stage for 
an even better 2023 in every critical measure.

We  have  set  ourselves  to  a  task  that  is  not  easy.  The  significant 
investment we are making now will ensure Invinity is better prepared 
commercially,  operationally  and  financially  as  we  take  rapid  and 
significant strides towards profitability. We are passionately committed 
to building a profitable, self-sustaining company that creates a net zero 
future  where  vanadium  flow  batteries  deliver  renewable  power  on 
demand. This means delivering large amounts of high-performance 
stationary energy storage at a price that customers find compelling 
and signing contracts in sufficient volume and at low enough costs 
that  we  generate  corporate  profit.  We  believe  our  next  generation 
product “Mistral” will play a key role in achieving these goals. 

We know what we need to do to achieve this ambition and we are 
doing it. Our accomplishments in 2022 were largely presented as 
goals in 2021. In my report for that year, I said that we wanted to 
achieve demonstrable progress in the fields of sales, partnerships, 
and delivery, recognise revenue on our existing VS3 product, and 
progress  development  of  our  next-generation  product,  code-
named “Mistral”. Our accomplishments in these key areas, despite 
(or perhaps enhanced by) the challenges we’ve encountered and 
overcome marks progress toward our goals and will help us deliver 
long-term value to our shareholders. 

We believe our accomplishments in 2022 allow us to state that we 
have successfully navigated the difficult transition from a company 
delivering pilot projects to a commercial entity. Our work continues 
to require significant effort and resources as we progress, but we 
are moving purposefully and determinately along our pathway to 
profitability.

Current  installations  of  each  BESS  (Battery  Energy  Storage 
System;  an  industry-standard  acronym  for  stationary  storage) 
incorporating Invinity’s products undergo a multi-step process. 
Contracted project objectives are turned into a storage system 
architecture  and  expressed  in  plans  and  documentation.  Our 
customer  prepares  the  battery  system’s  foundations,  grid 
connections  and  supporting  infrastructure.  Once  site  works 
are  complete,  we  deliver  the  battery  modules,  ensure  those 
modules  are  installed  correctly  and  bring  the  system  online. 
Demonstrating  that  the  battery  system  can  properly  store  and 
discharge  energy  allows  us  to  declare  the  BESS  “energised.” 
Once the system is integrated with site-level controls and fully 
operating, we formally hand it over to the customer and consider 
it “commissioned.”

During  2022,  we  commissioned  our  largest  site  to  date,  the  5 
MWh  system  at  the  Energy  Superhub  Oxford,  in  addition  to  a 
number  of  behind-the-meter  systems  including  a  project  with 
Scottish  Water  and  one  with  a  Taiwanese  industrial  group. 
We  also  delivered  two  California  Energy  Commission-funded 
projects: for the Soboba Band of Luiseño Indians and at Marine 
Corps  Air  Station  Miramar  near  San  Diego.  In  August,  we 
energized our project with the European Marine Energy Centre 
in the Orkney islands.

Successfully closing a significant number of deals, delivering those 
products around the world and ensuring they meet our customers’ 
requirements provides important proof of our commercial status. 
It demonstrates that the market wants our batteries and that we 
have built an organisation  capable  of  converting market  interest 
into revenue.

We and our customers continued to experience various external 
challenges, including ongoing supply chain disruptions, in 2022. 
Those  disruptions  caused  some  delays  but  did  not  impact  our 
ability  to  sign  nearly  40  MWh  of  sales  contracts  for  our  VS3 
batteries. In doing so, the Company sold more batteries in the last 
three months of 2022 than in Invinity’s entire history. These sales 
were based in part on our ability to demonstrate to new customers 
how  existing  projects  are  already  delivered  and  operating.  I  am 
grateful to the entire Invinity team for the work they carried out to 
make this happen. 

DELIVERY AND SALES
Our success derives from delivering our proven technology to a 
growing list of customers. I am pleased to report that last year we 
delivered more than 100 individual VS3 modules and commissioned 
more than 200 to customers across three continents. At the time 
of  writing,  we  believe  we  have  delivered  more  individual  flow 
batteries—each  capable  of  operating  independently—than  all 
other flow battery companies combined across their histories.

Importantly, I believe these recent contract wins, expected to be 
delivered at positive gross margin, combined with robust growth 
in the Company’s sales pipeline, reflect an inflection point in the 
commercial  acceptance  of  Invinity’s  products.  The  Company  is 
increasingly well positioned to address the growing global demand 
for  commercial,  non-lithium  and  longer-duration  energy  storage 
solutions.

I  stated  in  my  previous  report  that  our  strategy  included  finding 
substantial  partners  who  can  represent  us  and  our  products 
by  providing  sales,  installation  and  service  support.  These 
partnerships are valuable for two reasons.

First,  they  allow  us  to  reach  a  wider  market  without  incurring 
significant costs that would delay profitable growth for the Company, 
particularly outside our core markets of Europe, North America and 
Australia. Second, our reputation is enhanced through association 
with established entities that have chosen to work with us because 
they  recognise  the  size  of  the  opportunity  and  the  advantages 
of our product. I am proud that Invinity has developed important 
relationships with Hyosung Heavy Industries in Korea, Everdura 
Technology Company and Bei Ying International in Taiwan, Indian 
Energy in the U.S., and post period, with Dawsongroup in the UK 
and Ideona Group and STS Group in the EU. I am delighted that 
we have  closed sales opportunities with each of these  partners 
and are developing further opportunities that have contributed to 
our growing pipeline of commercial deals.

Our partners recognise the critical need for energy storage, not just 
to use renewable energy effectively but to avoid relying on more 
expensive,  higher-emissions  sources  of  power  when  renewable 
sources—wind,  solar  and  tidal—are  not  available.  They  believe 
that  alternative  chemistries  are  vital  to  overcome  lithium-ion 
batteries’ limitations in safety and lifetime and because the demand 
for  lithium-ion  batteries  needed  to  support  the  electrification  of 
transport is already impacting global supplies and has increased 
the price of lithium and other battery materials significantly. 

Our  ability  to  deliver  our  product  has  been  enhanced  through 
establishing  a  manufacturing  relationship  with  long-time  Invinity 
supporter Suzhou Baojia New Energy Technology Co. (Baojia). They 
have taken on the manufacturing of our balance of system from our 
previous  manufacturing  partner,  BCI,  who  provided  an  important 

foundation  for  Invinity  in  the  early  years  and  for  whose  continued 
support we are grateful. With Baojia’s larger facilities, we are already 
achieving greater production scale, having so far shipped more than 
25 MWh of batteries directly to project sites and our facilities in both 
Bathgate  and  Vancouver.  This  level  of  output  bodes  well  for  the 
future, brings us greater cost efficiencies and enhances our ability to 
expand to meet the growing demand for our products.

PROGRESSING MISTRAL
Our  most  important  partnership  is  with  Gamesa  Electric  and 
Siemens Gamesa Renewable Energy (SGRE) as reflected in our 
previously announced Joint Development and Commercialisation 
Agreement.  Nothing  on  our  pathway  to  profitability  is  more 
important than the investment we are making to progress the joint 
development  of  our  next-generation  product.  The  objectives  for 
Mistral are simple, albeit quite challenging to realize: lower costs 
substantially  from  our  current  VS3  product  while  increasing  the 
suitable project size addressed by our product from 10s to 100s of 
MWh. These objectives are captured in a single metric: Levelized 
Cost of Storage (LCOS). LCOS captures the total cost of operating 
a BESS, including purchase, operating costs and efficiency, on a 
throughput (in MWh) basis. Mistral is targeting the best LCOS of 
any BESS, bar none, and to beat years early the U.S. Department 
of Energy’s LCOS target of $50/MWh by 2030.

We  are  pleased  with  the  progress  we  are  making  on  Mistral 
alongside  our  partner.  We  will  not  be  making  any  specific 
announcements of Mistral’s specifications until we can do so jointly 
and in full confidence that Mistral’s capabilities are validated in field 
trials and large-scale internal tests. While this discipline may not 
be  customary  in  our  field—we  often  hear  of  the  ‘revolutionary’ 
importance  of  what  is  only,  in  reality,  a  lab  demonstration,  or  of 
the ‘sales success’ of a company that signs deals at a fraction of 
their production cost or has yet to prove capabilities in the field—
it  is  what  you  should  expect  from  us  as  an  increasingly  mature 
multinational product company.

CORPORATE STRENGTH
We  continue  to  be  grateful  for  the  support  of  our  investors.  The 
funds we raised in late 2021 enabled us to progress our pipeline, 
sign a record volume of business and invest in Mistral. The support 
shown by our existing and new shareholders, particularly including 
Everbrite,  in  March  of  this  year  has  provided  sufficient  working 
capital to support and grow our existing operations and to advance 
Mistral to its next critical milestone.

We  are  not  alone  in  enduring  delays  and  having  challenges  to 
overcome  that  cost  more  than  anticipated.  The  pandemic  had 
a significant impact on Invinity as it did on countless companies. 
But we believe we are alone, and happily so, as the only provider 
of  products  for  non-lithium  BESS  that  is  successfully  deploying 
megawatt-scale  projects  to  customers  at  positive  gross  margin, 
and we are doing so in multiple countries. We celebrate this major 
step toward corporate profitability, a step we could not have taken 
without our shareholders’ support.

LOOKING TO THE FUTURE
A future electric grid without renewables as its primary energy 
source  simply  will  not  meet  global  objectives  for  carbon 
emission reduction. Yet that future renewable-intensive electric 
grid will be unstable—unless it incorporates adequate energy 
storage.  Grid  instability  is  already  increasing  with  greater 
renewable generation, and already significant disruption events 
have occurred in the UK, the U.S., Australia and elsewhere.

No single technology will meet all future needs for stationary battery 
energy  storage,  not  even  our  vanadium  flow  battery  technology. 
Instead,  battery  characteristics  will  be  matched  to  requirements. 
Governmental  initiatives  globally  seek  to  stimulate  more  energy 
storage generally and to support domestically produced alternatives 
to  lithium-ion  batteries  able  to  discharge  for  longer  durations  or 
operate with greater safety and lower total costs. Invinity has and 
will continue to be a significant beneficiary of these initiatives.

The  macro  environment  continues  to  strongly  support  the 
Company’s  business.  To  meet  this  opportunity,  Invinity  has 
determined that a four-part strategy is required: 1) deliver projects; 
2) close new and larger deals; 3) progress Mistral; and 4) advance 
our operational excellence. Our view of the significance of each of 
these priorities:

1)  Delivering  contracted-for  projects  is  not  just  an  obligation 
incurred upon signing a contract; rather, each one is an opportunity. 
Every  installation  further  demonstrates  that  our  technology  is 
proven and exceeds customer expectations. We gain critical field 
experience that further refines our product development. And we 
earn revenue.

2) Closing new deals enhances our position as the clear leader 
in  large-scale,  low-LCOS  energy  storage  that  can  be  deployed 
anywhere and provides for future revenue.

3) Mistral will transform our product offering from competitive 
to compelling for a great many applications, becoming a platform 
for profitable revenue growth bounded, we believe, not by demand 
but by supply.

4)  Operational  excellence  is  based  on  putting  in  the  right 
processes and operations now and not waiting until the need is 
acute. This focus is vital to maintaining our growth trajectory and 
enabling us to adroitly address the inevitable challenges—whether 
supply chain, competition, macro events, or something else—that 
we encounter.

In  my  2021  report,  I  acknowledged  the  challenges  from  supply 
chain  disruptions  that  we  had  underestimated  and  sales 
processes that took longer than we anticipated. We continued to 
see challenges in 2022, but we have entered 2023 with what we 
believe  is  the  best  technology  we’ve  ever  deployed,  the  largest 
order  book  we’ve  ever  had,  and  the  most  sales  prospects  by 
far.  At  the  same  time,  we  have  made  great  strides  toward  the 
development  of  our  next-generation  VFB  which  promises  both 
improved performance and significantly increased margins. It is 
hard to contain our excitement at the future which lies ahead for 
us.  Energy  storage  is  the  key  to  unlocking  the  potential  for  the 
world to be powered by clean energy and we are well on our way 
to achieving a profitable position at the heart of this fundamentally 
important industry.

I remain highly optimistic for the future of our business and remain 
confident that we will realise our potential. I therefore thank you 
again for your support for Invinity and look forward to bringing you 
more success in 2023.

To  this  end,  the  Company  continues  to  develop  its  next-
generation battery, code-named “Mistral”. Mistral is expected to be 
manufactured at significantly lower cost than the Company’s existing 
product, the VS3, and 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  and  reducing  the  Company’s  reliance  on  external 
sources of funding.

2022 FINANCIAL PERFORMANCE
I am pleased to report that total income including sales revenue and 
project related grant income increased to £3.6 million in 2022 (2021: 
£3.2 million). Revenue is recognised against projects when specific 
performance obligations related to those projects have been satisfied. 
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.

Another positive development during the period was that the Company 
was  able  to  show  a  materially  reduced  cost  of  delivering  its  VS3 
products to customers, resulting in a significant £3.2 million reduction 
in the provision for contract losses. This contributed to an 12% year-on-
year reduction in operating loss and a material improvement in gross 
margin. Invinity was also able to narrow the loss before tax by 13% 
to £18.5 million for the year. These movements represent important 
progress as the Company moves along the path to achieving industry 
standard gross margins which are expected to be delivered with the 
launch of the Company’s next-generation product. 

Administrative  costs  were  £19.0  million  (2021:  £14.4  million),  an 
increase of £4.6 million primarily represented by investment in people 
with staff costs of £10.3 million in 2022 (2021: £9.0 million) and IT costs 
of £1.2 million in 2022 (2021: £0.6 million). Research and development 
costs  that  did  not  meet  the  threshold  for  capitalisation  and  were 
therefore expensed were £2.6 million (2021: £1.8 million). In addition, 
professional fees increased to £3.0 million in 2022 (2021: £2.0 million) 
as a result of predominantly non-recurring matters and costs of £1.0 
million  in  2022  (2021:  £0.2  million)  were  incurred  in  relation  to  the 
transfer of manufacturing from BCI to Baojia at year end.

Year-on-year  cash  outflow  from  operations  of  £21.9  million  (2021: 
£23.0 million) is largely consistent with the prior year. 

GROWTH AND INVESTMENT – LOOKING TO THE FUTURE
In  addition  to  the  delivery  and  commissioning  of  contracts  for 
battery systems with customers, 2022 has been a year of growth 
in  the  underlying  business  of  the  Company  as  evidenced  by  a 
significant  increase  in  the  number  of  new  contracts  for  battery 
systems closed in the year. In total, 7 new sales contracts were 
signed in 2022 with a total potential revenue value of £22.0 million. 
Each of these new contracts (other than one entered for strategic 
reasons) are currently expected to be delivered at a positive gross 
margin as improvements are made to the Company’s supply chain 
and  manufacturing  infrastructure.  As  a  Company,  we  continue 
build  on  the  experience  gained  from  systems  delivered  to  date 
and seek to use those learnings improve operational and financial 
performance related to contracts.

The  expected  growth  in  the  business  has  required  investment 
to  be  made  in  a  number  of  areas  including  people,  facilities, 
infrastructure and inventory. Headcount increased by 23 people 
to efficiently manage the backlog of orders for delivery in 2023 
and  beyond.  Other  specific  operational  investments  made  in 
2022 included leasehold improvements related to our production 
facilities and offices of £0.4 million and an increase in prepayments 
and deposits of £1.3 million. Buying the equipment necessary to 
build our batteries in advance helps the Company to reduce the 
delivery  timeframe  for  its  vanadium  flow  battery  systems  and 
accelerates  the  associated  construction  and  installation  of  the 
units,  advancing  revenue  recognition  and  as  a  result,  prepaid 
inventory rose £1.0 million to £5.0 million.

These investments are all focused on improving contract delivery, 
logistics and providing the necessary funding for further research 
and  development  as  Invinity  moves  forward  on  its  pathway  to 
profitability. That next stage will come as we mature and ultimately 
launch  our  next-generation  product,  code-named  “Mistral”, 
currently in joint development with Siemens Gamesa. 

All bar one of the Company’s most recent sales contracts have been 
signed with a forecast positive margin. 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.

FUNDING AND NET WORKING CAPITAL
At  31  December  2022  the  Company  had  net  working  capital 
of  £4.3  million,  inclusive  of  cash  and  cash  equivalents  of 
£5.1 million. The cash balance of £5.1 million included the net 
cash proceeds from the initial drawdown of US$2.5 million from

a US$10.0 million convertible loan instrument (the “Investment 
Agreement”) taken out with Riverfort Global Opportunities PCC 
Ltd (“Riverfort”) and YA II PN (“Yorkville”) that was entered into 
on 14 December 2022 to provide additional working capital for 
the business. 

The  Company  only  made  one  drawdown  under  the  Investment 
Agreement.  This  was  due  to  the  Company  successfully  raising 
additional  equity  capital  of  £23.0  million  through  a  placing, 
subscription and open offer in March 2023. Part of these proceeds 
were  used  to  redeem  in  full  the  balance  then  outstanding  under 
the  Investment  Agreement.  In  doing  so,  the  warrants  that  were 
issued alongside the Company entering the Investment Agreement 
were repriced to reflect the open offer price of 32p. Those repriced 
warrants  remain  in  place.  Notwithstanding,  any  proceeds  from 
the future exercise of the warrants held by each of Riverfort and 
Yorkville will be distributed 97% to the Company and 3% to Riverfort 
and Yorkville.

Strategic Investment 
Importantly, and 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. 

This strategic investment underscores the development progress 
of the Company since the 2020 merger transaction that formed the 
Group as it is today and is intended to support a closer strategic 

relationship  for  the  deployment  of  vanadium  flow  batteries  in 
Taiwan and further afield.

Invinity sees strategic partnerships and investment as an important 
pillar  of  its  future  corporate  growth  and  as  previously  disclosed, 
discussions with a number of potential strategic partners remain 
ongoing.  

GRANT FUNDING
The participation in grant schemes is an important source of funds 
for the Company. Grant awards may be project specific or general in 
nature. Grants that are more general in nature typically help to defray 
ongoing costs such as research and development where projects are 
seen as strategically important by local or national governments.

Other grant funding is more project specific and aimed at increasing 
the application of new technology and its commercial uses.

In 2022, the Company received £0.6 million of grant funding related to 
a specific customer project under Phase One of the UK Government’s 
Longer  Duration  Energy  Storage  (LODES)  Competition  that  is 
administered by the Department for Energy Security and Net Zero 
(DESNZ). As this income was project specific, it has been identified 
in the profit and loss account alongside but separate to revenue on 
account of it being recognised against direct costs. 

GOING CONCERN
In assessing whether the Group has the ability to continue as a 
going concern the Directors have modelled cash flow forecasts for 
a period up to 31 December 2024. The Directors have prepared a 
base case scenario that assumes the 14.5m Short-Term warrants 
originally  granted  in  2021  (“Short-Term  Warrants”),  the  terms  of

which are proposed to be amended as set out below are exercised 
before  June  2024.  Under  this  scenario  the  Group  would  expect 
to  remain  cash  positive  for  the  period  up  to  31  December  2024 
assessed for going concern purposes. The forecast does indicate 
that  the  Group  would  move  into  negative  cash  shortly  after  the 
period assessed for going concern as a result of working capital 
investment on future sales. The Group would defer any working 
capital investment if it were to result in exhausting all cash. This 
forecast is also based on delivering existing signed sales contracts 
during 2023 as per forecast gross margins and existing and future 
sales contracts during 2024 at anticipated positive gross margins. 
The  Directors  recognise  there  is  a  risk  that  the  Short-Term 
Warrants will not be exercised if they are not ‘in the money’ before 
the expiry date and given it is not at the discretion of the Group. 

Company is now planning to seek the approval of Warrant holders at 
a general meeting, notice of which will be given shortly, to make the 
following amendments to both the Short and Long-Term Warrants. 
The Company intends to seek approval to amend the Short-Term 
Warrant subscription period to 16 December 2023 (the Long-Term 
warrant subscription period will remain unchanged at 16 December 
2024) and amend the exercise prices of the Short and Long-Term 
warrants to 50p and 100p respectively. There can however be no 
certainty that such a change in the terms will be approved. 

In  assessing  going  concern  the  Directors  have  also  prepared  a 
severe but plausible downside scenario which forecasts delivery 
of existing and future sales being made during 2024 being delayed 
beyond  June  2024  and  forecasted  margins  not  being  achieved. 
Under this scenario the Group would exhaust all available cash by 
April 2024 and it will be necessary to raise further funding within 
the next 12 months in order to continue trading and deliver on the 
strategic objectives. 

The Directors are in the process of evaluating potential additional 
funding  options  from  potential  strategic  investors  but  no  such 
funding is committed as at the date of approval of these financial 
statements.  The  Group  has  been,  and  continues  in,  active 
discussions with a number of identified strategic investors and is 
confident that it will be able to conclude an equity investment from 
one or more of such parties within the period up to 31 December 
2024  assessed  for  going  concern  purposes.  The  Directors  also 
note  that  the  Company  concluded  an  initial  strategic  investment 
from Everbrite Technology Co., Ltd. for £2.5 million in March 2023 
which  gives  them  confidence  that  the  Company  is  capable  of 
attracting further strategic investment.

Due to the uncertainty in relation to obtaining additional funding this 
indicates the existence of a material uncertainty that may cast significant 
doubt about the Group’s ability to continue as a going concern.  

The  Directors  have  also  prepared  an  alternative  ‘adjusted  base 
case’ scenario which does not include the exercise of the Short-
Term  Warrants  but  also  adjusts  forecasted  costs.  The  Directors 
have a plan to adjust costs in a scenario where it does not look like 
the Short-Term Warrants will be exercised. This plan includes the 
following:

The financial statements do not include the adjustments that would 
result if the Group were unable to continue as a going concern. 

In addition to the issues discussed above, the directors have also 
reviewed  other  varying,  and  wide-ranging  information  relating  to 
both present and future conditions when reaching their conclusion 
regarding going concern. These included the:

   Non-payment or delayed payment of forecasted bonuses;
   No increase or delayed increase in salaries across the Group;
   Delayed recruitment of additional headcount; and

 Reduction in planned increase in research and development 
expenditure.

Under the adjusted base case the Group would expect to remain 
cash  positive  for  the  period  up  to  31  December  2024  assessed 
for going concern purposes. Therefore the Directors believe it is 
appropriate to prepare the accounts on a going concern basis. 

The  Short-Term  Warrants  were  initially  granted  in  2021  with  an 
exercise price of 150p and an expiry date of 15 September 2022. 
On 31 August 2022, the holders of the Short-Term Warrants agreed 
at a general meeting of Short-Term Warrant holders to amend the 
expiry date of the Short-Term Warrants to 15 September 2023. The

RISK MANAGEMENT REPORT 

The Group’s business exposes it to a broad range of risks. Invinity’s approach to managing these risks is to create a system of internal 
controls. This system looks to manage, rather than eliminate, risk and, whilst the Group has an Audit & Risk Committee (financial risk) and an 
Environmental, Social & Governance Committee (non-financial risk), it is seen as the responsibility of the entire Board.

SUSTAINABILITY – INVINITY’S APPROACH TO THE ESG AGENDA

As  a  Company,  and  as  individuals,  we  are  committed  to 
taking  action  on  climate  change.  We  also  understand  the 
importance of a ‘Just Transition’ to a low-carbon economy, 
with  no  one  left  behind.  This  commitment  underscores 
our  approach  to  operating  responsibly  and  sustainably  in 
the  pursuit  of  our  corporate  goals,  which  themselves  are 
intrinsically linked to accelerating the clean energy transition 
and achieving net zero. 

The  ESG  Committee,  formed  in  June  2022,  has  a  mandate  to 
oversee, inform and guide our approach to Environmental, Social 
and  Governance  (ESG)  issues  and  ensure  our  performance 
against ESG metrics generates additional value for our business, 
shareholders  and  wider  stakeholders.  The  Committee  is  also 
responsible  for  the  regular  and  transparent  disclosure  of  our 
performance on an ongoing basis and it is with this goal that I am 
pleased to report on progress achieved to date. 

GUIDING PRINCIPLES
Through  considered  discussion,  Invinity’s  Board  has  agreed  a 
defined set of ESG principles – outlined below - that play an integral 
role in helping to achieve our commitment to the ESG agenda:

 Accelerate, through our products and services, the global transition 
to support national and international net zero targets;
 Champion innovation and thought leadership in all we do;
 Be a great place to work;
 Work in collaboration with all of our stakeholders; 
 Engage with local communities to share knowledge capital and 
create opportunity.

A LEADER IN THE CLEAN ENERGY AND NET ZERO SECTOR
Invinity  is  proud  to  have  been  one  of  the  first  recipients  of 
the  London  Stock  Exchange’s  Green  Economy  Mark,  which 
recognises  companies  that  derive  50%  or  more  of  their  total 
annual revenues from products and services that contribute to the 
global green economy. The underlying methodology incorporates 
the  Green  Revenues  data  model  developed  by  FTSE  Russell, 
which helps investors understand the global industrial transition 
to a green and low carbon economy with consistent, transparent 
data and indices.

Invinity is also pleased to have been included as part of the Active 
Net Zero Clean Energy Index, a pan-European investment index 
established in 2021 to assist investors wishing to gain exposure 
to companies which are actively enabling the energy transition. 

CASE STUDY:  
Accelerating the energy transition with Invinity’s VFBs
Our  vanadium  flow  batteries  are  being  installed  at  sites  across 
the  world  to  complement  renewable  energy  generation  such  as 
solar  PV,  wind  turbines  and  tidal  power,  creating  ‘dispatchable’, 
on-demand, clean power. This already delivers significant carbon 
savings annually and enables renewables to compete directly with 
fossil fuel powered generation for the first time, accelerating the 
phase-out of coal and gas from the global generation mix, without 
having a destabilising effect on the grid.

Three  significant  installations  of  Invinity  batteries  will  alone 
contribute  a  reduction  of  more  than  24,000  tonnes  of  annual 
greenhouse gas emissions. These are the: 

ESG CHAMPIONS
Further  supporting  the  work  of  the  ESG  Committee  are  our 
ESG  Champions,  appointed  from  amongst  Invinity  staff  in  the 
Company’s  primary  manufacturing  locations  in  Scotland  and 
Canada. Their responsibilities include reporting to the Committee 
on progress of ongoing and focused ESG and CSR initiatives to be 
adopted, subject to the Committee’s agreement.

PLAYING OUR PART IN THE CIRCULAR ECONOMY
Invinity’s  VFBs  are  a  natural  fit  for  the  circular  economy  as  the 
key  product  components  consist  of  easily  and  widely  recyclable 
materials.  Our  batteries  do  not  contain  rare  earth  or  ‘conflict’ 
minerals, such as cobalt, and the vanadium electrolyte does not 
degrade with use, meaning that nearly 100% of the vanadium itself 
can be recovered from the electrolyte for use in other applications. 
This limits the need to constantly utilise newly mined raw materials 
during the life of the battery.

CASE  STUDY:  In  further  support  of  our  goal  to  promote  the 
circular economy, in January 2023, the Company was pleased to 
announce a partnership with one of the UK’s largest commercial 
asset rental businesses, Dawsongroup plc, which will see Invinity 
batteries  rented  to  commercial  customers  in  the  UK.  Together, 
Invinity and Dawsongroup aim to roll out an energy storage rental 
solution which could fundamentally change the economics of asset 
ownership for energy storage and vastly reduce waste by allowing 
Invinity’s batteries to be repositioned as customer needs evolve. 

MANAGING OUR IMPACTS
As  a  fast-growing  company  that  provides  solutions  which  help 
avoid  and  remove  emissions,  we  are  fully  committed  to  taking 
action  to  reduce  our  own  carbon  footprint.  In  recognition  of  the 
United  Nations  Race  to  Zero  Campaign,  Invinity  has  been  a 
signatory on the SME Climate Commitment since 2021.

The Company also recognises the importance that global supply 
chains play in our business and the role that manufacturers such 
as itself can play in challenging our suppliers to meet the same high 
levels of ESG compliance that we do. Invinity has a range of policies 
which are reviewed and adopted each year at Board level which 
relate to topics including a supplier code of conduct which stipulates 
that our suppliers must, in addition to conducting their business in 
compliance  with  law,  deliver  long-term  social,  environmental  and 
economic benefits for the communities in which they operate.

OUR CARBON FOOTPRINT
Invinity  reports  its  carbon  footprint  in  compliance  with  The 
Greenhouse  Gas  Protocol  (the  world’s  most  widely  used 
greenhouse gas reporting framework) and with the SME Climate 
Commitment. In line with these requirements, the Company reports 
primarily on its direct emissions (Scope 1) and indirect emissions 
arising from electricity, heat or steam consumption (Scope 2). For 
calculating our carbon footprint, we utilise an operational control 
accounting approach which involves accounting for all emissions 
from operations over which the Company has control. It does not 
include emissions from operations over which the Company may 
have an interest, but no control. 

In line with SME Climate Commitment guidelines, Invinity falls under 
the category of “fast growing SMEs that provide solutions which 
avoid or remove emissions as their core business”. Therefore, it 
is  considered  appropriate  for  the  Company  to  report  its  carbon 
footprint  on  an  ‘intensity’  basis,  using  the  metric  of  grammes  of 
CO2 equivalent per £ of annual revenue.

SOCIAL IMPACT
We empower our people, partners and customers to change the 
world.  Invinity  is  committed  to  driving  forward  the  social  value 
agenda and to making a positive change through our operations 
and  wider  activities.  Our  work  in  this  area  over  the  year  took  a 
number of different forms:

SupportingourHard-workingTeam
We remain committed to being a great place to work and, in support 
of this initiative, we provide health and wellbeing support for all our 
staff, helping our people to remain safe and healthy: 

   Invinity offers a standard benefits package which is accessible

laws, includes healthcare and other supplementary benefits.

   All Invinity employees also have access to an employee assistance 
programme, providing confidential legal and financial advice, along 
with access to counselling and other services at no cost to employees.

subscriptions  in  order  to  maintain  their  skills  and  support  their 
further professional development. 

PlayinganActiveRoleintheLocalCommunity
Approximately  50%  of  our  staff  live  less  than  10  miles  from  work 
and  we  are  committed  to  playing  a  role  in  our  local  communities, 
sharing  our  knowledge  and  providing  new  opportunities  to  those 
in the local area. Our work in this area is particularly focussed on 
partnerships with the education sector, providing the opportunity for 
work experience and internships and supporting national initiatives 
such as the UK Government’s STEM agenda. (See box) 

CASE STUDY: Invinity’s Internship / COOP programme

Commercial Internship Programme, London, UK
We have had four Energy Storage Analyst Interns who have joined 
our  UK-based  Commercial  team  since  2018  and  subsequently 
gone on to be permanent employees. They were all involved with 
early-stage discussions with clients, pulling together research and 
market analysis to further the case for energy storage developments 
and  identifying  future  commercial  opportunities.  This  internship 
was  designed  to  provide  valuable,  first-hand  experience  in  a 
professional setting and a chance to put their academic learning 
into practice within the green economy. Our interns reported that 
they gained valuable insights into the industry and learned how 
to conduct techno-economic analysis of energy storage projects, 
generate proposals and communicate with customers. Those who 
took  up  full  time  positions  with  Invinity  became  Energy  Storage 
or  Business  Development  Analysts  with  one  being  promoted 
subsequently to Commercial Programme Manager. In the nearly 
four years the programme has been running, it has proven to be 
valuable to all parties and Invinity intends to continue and expand 
the programme in the years to come.

COOP Programme, Vancouver, Canada 
A  third  year  Sustainable  Energy  Engineering  student  at 
Simon Fraser University joined us as an Energy Storage Intern 
for  the  September  2021  four-month  term.  They  were  primarily 
involved in supporting early-stage commercial discussions with 
clients and working on pulling together energy market research for 
North America to investigate the potential for long duration energy 
storage deployment in various territories. They also worked on

a number of small-scale projects carrying out techno-economic 
modelling  for  clients  to  help  support  the  development  of  the 
client’s business case. This was their first significant experience 
in dealing with electricity markets and utilities, providing a good 
opportunity  to  learn  the  fundamentals  of  the  various  energy 
markets  we  were  investigating  as  well  as  gain  a  selective 
understanding  of  the  various  mechanisms  by  which  energy 
utilities charge their customers. There was a significant amount 
of data processing and analysis which provided the student with 
an important opportunity to interface with many members of the 
global Invinity team and work with a number of proprietary end-
to-end energy modelling tools that we had created in-house.

Second year Engineering Physics student at the University 
of  British  Columbia  joined  us  as  a  Software  Co-op  for  the 
January 2022 four-month term. The focus for the co-op term 
was  to  develop  new  features  within  our  existing  software 
platform.  They  worked  in  the  software  team  and  during  their 
term developed a tool that upgrades our Firmware in the field. 
This was their first co-op experience and they gained valuable 
knowledge  of  software,  taking  further  what  they  had  learned 
on  engineering  development  in  their  degree  and  applying 
it  in  a  professional  setting.  It  was  an  opportunity  for  them  to 
make an impact in a team environment where their code had 
an  impact  on  others’  development  and  as  such  their  focus 
was on learning to build robust code that is maintainable and 
secure. They also gained first-hand skills and knowledge from 
experienced software engineers in the team.

ChampioningEquality,DiversityandInclusion
Invinity continues to expand our commitment to promoting Equality, 
Diversity, and Inclusion (EDI). We remain committed to maintaining 
and  improving  a  workplace  where  everyone  can  flourish  and 
our  approach  addresses  all  elements  of  our  operations  from 
recruitment to promotion, career development and the creation of 
an outstanding working environment.

CASE STUDY: Women in Technology Roundtable
In  2022,  Invinity’s  HR  team  started  a  Women  in  Technology 
roundtable. The purpose was to be an open forum for the women 
at  Invinity  and  their  specific  challenges.  All  women  from  all 
departments were invited to the monthly meetings. Topics raised 
for discussion were selected by female employees, and included; 
dealing  with  imposter  syndrome,  body  language,  increasing 
Women  in  STEM,  work  and  parenthood,  and  work-life  balance. 
Our intention is to continue the programme in 2023 and expand by 
inviting guest speakers to provide additional insight and guidance 
to our female employees. As a result, we hope to increase female 
representation both internally and externally.

GOVERNANCE
Invinity’s Board of Directors believes that strong corporate governance 
and risk management are key to the delivery of shareholder value. The 
business is underpinned by a comprehensive framework of policies 
and risk management systems and the Board has adopted the Quoted 
Companies  Alliance  Corporate  Governance  Code  2018  (the  QCA 
Code)  as  its  corporate  governance  code  which  it  believes  provides 
a flexible model allowing our corporate governance to evolve as the 
business grows.

Further details on the Company’s corporate governance practice and 
compliance with the principles of the QCA Code are provided in the 
Governance section of this Annual Report and on the website. Details 
of the risk management systems are provided in the Risk Management 
section of this Annual Report.

GOVERNANCE REPORT

INTRODUCTION ON THE GOVERNANCE REPORT  
FROM THE CHAIRMAN, NEIL O’BRIEN
Invinity is listed on the Alternative Investment Market (“AIM”) of the 
London Stock Exchange. The Company’s shares are also dual-listed 
on the Apex segment of the Aquis Stock Exchange Growth Market 
(AQSE) and the Company’s short-term and long-term warrants are 
listed  on  the  Access  segment  of  the  AQSE.  During  the  year,  the 
Company’s shares also started trading on the OTCQX in the U.S.

The Company is required to apply a recognised corporate governance 
code  and  the  Board  has  adopted  the  Quoted  Companies  Alliance 
Corporate Governance Code (the “QCA Code”), which is designed 
for  small  to  mid-sized  companies  and  which  has  been  adopted  by 
many AIM companies. The Board has concluded that the QCA Code 
remains  the  most  appropriate  corporate  governance  code  for  the 
Company. 

The  Board  has  considered  how  the  Company  applies  the  ten 
principles of the QCA Code and the Governance Report includes the 
required disclosures and explanations where relevant. Further details 
of  the  Company’s  corporate  governance  practices  are  provided  on 
the  Company’s  website  in  the  Investors’  section  under  Corporate 
Governance. 

Corporate Governance Statement 
The  Board  recognises  that  good  governance  helps  to  underpin 
the  foundations  of  a  solid  and  successful  business  and  delivery  of 
shareholder value. Invinity’s Board, led by the Chairman, is committed 
to maintaining high standards of corporate governance for which the 
Directors are accountable to shareholders and other stakeholders and 
to ensuring that the Company’s values are communicated and upheld 
across the Group. The Board recognises that corporate governance 
practices will need to be regularly reviewed as the Company grows to 
ensure that they remain appropriate and effective. 

During 2021, the corporate governance framework was strengthened 
with  a  number  of  initiatives  including  the  appointment  of  a  Senior 
Independent  Director  and  a  new  Non-Executive  Director,  the 
introduction  of  a  Board  performance  appraisal  process  and  the 
streamlining of Board processes including risk management.

During 2022, the Board established an ESG Committee to ensure that 
the Company delivers on its objective of operating responsibly and 
sustainably. The Board also established a Standing Committee of the 
Board to deal with adhocmatters 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.

Corporate culture 
The  Company  is  committed  to  ensuring  that  there  is  a  healthy 
corporate culture. A number of policies and procedures have been put 
in place to ensure that ethical and transparent behaviour is recognised 
and followed across the Group and these include: 

    Code of Conduct
    Whistleblowing Policy 
    Equal Opportunities Policy
    Share Dealing Code 
    Anti-Bribery and Corruption Policy
    Health and Safety Policy 
    Modern Slavery Statement
     Procurement Policy
     Social Impact Policy
    Environmental Impact Policy

Annual Report and Financial Statements 2022UK  /  U.S.  /  CANADA  /  AUSTRALIA INTRODUCTIONSTRATEGIC REPORTGOVERNANCEFINANCIAL STATEMENTSInvinity Energy Systems plc 
 
Board composition
The  Board  currently  consists  of  a  Non-Executive  Chairman,  three 
Executive  Directors,  a  Senior  Independent  Director  and  two  other 
Non-Executive Directors. 

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

During  2022,  Rajat  Kohli  replaced  Jonathan  Marren  as  Senior 
Independent  Director  following  Jonathan  Marren’s  appointment  as 
Chief Development Officer and subsequently as Interim Chief Financial 
Officer following Peter Dixon-Clarke’s resignation as Chief Financial 
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. 

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. 

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. 

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. 

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. 

Independence of Directors 
The Board considers that the Chairman and all the Non-Executive 
Directors were independent for the whole of the 2022 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 17 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. 

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, 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. 

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.

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.

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.

Board performance evaluation 
Since  the  year  end,  an  internal  performance  evaluation  of  the 
Board  has  been  undertaken.  Each  Board  member  completed  a 
questionnaire which focused on strategy, risks and controls, Board 
structure  and  development,  Board  processes  and  the  work  and 
composition of the Board committees. The responses were collated 
and  summarised  by  an  external  company  secretary  and  the  key 
conclusions tabled at a Board meeting.

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.

present. The external auditors had discussions with the chairman 
of the Committee during the course of the year and also met the 
Committee members without management present. 

Only  members  of  the  Committee  have  the  right  to  attend  the 
meetings  of  the  Committee  but  the  Committee  can  invite  the

on financial risk; 
  the accounting policies and practices of the Group; 
  the  annual  and  interim  financial  reporting  carried  out  by  the

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.

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

REPORT OF CHAIR OF THE 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 2022. 

The Report is divided into two sections:

  The Policy report which sets out the current Remuneration Policy; 
  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 2022. It also sets out details of the implementation 
of the Remuneration Policy for Executive and Non-Executive 
Directors for the year ending 31 December 2023.

Executive  Director  compensation  had  not  been  adjusted  since 
May  2010  when  the  company  operated  as  redT  Energy  and 
therefore an outside review was warranted. 

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.

In early 2023, the Remuneration Committee engaged Alvarez and 
Marsal (“A&M”) to review Executive and Non-Executive Director 
compensation  and  provide  benchmarks  and  recommendations 
compared to its AIM-listed peers. It was noted that certain Non-

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 Development Officer (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. 

Performance metrics 

Not applicable for benefits and pension package. 

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

Annual Bonus 

Purpose and link to strategy  

To reward the achievement of corporate targets.

Operation  

Opportunity  

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.

 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.

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 

Maximum annual opportunity 

 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. 

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

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
a) Annual bonus 
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 
already left. 

b) Option Plan
In relation to awards granted under the Option Plan, all unvested options will lapse on cessation of employment. In Good leaver and 
Intermediate leaver circumstances (as defined in the Option Plan rules), all vested options will be retained and will be exercisable for a 
period of six months after the cessation of employment or 12 months in the case of death. The Committee has discretion to further extend 
the exercise period for Intermediate leavers and to allow the vesting of all or part of the unvested portion of an option for Good leavers. 

In the event of change of control of the Company, all vested options will remain exercisable for a period of six months after the change 
of control and the Committee has the discretion to allow the vesting of all or part of the unvested portion of an option. Subject to the 
agreement of any acquiring company, option holders may be offered the opportunity to exchange their options for equivalent options over 
shares in the acquiring company for a period of up to six months from the change of control taking effect.

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 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.

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,  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  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. 

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 24-
25, 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:

INDEPENDENT AUDITORS’ REPORT

to the members of Invinity Energy Systems plc

REPORT ON THE AUDIT OF THE FINANCIAL STATEMENTS

Opinion
In our opinion, Invinity Energy Systems PLC’s group financial statements:

 give a true and fair view of the state of the group’s affairs as at 31 December 2022 and of its loss and cash flows for the year then ended;

  have been properly prepared in accordance with UK-adopted international accounting standards; and
  have been prepared in accordance with the requirements of the Companies (Jersey) Law 1991.

We have audited the financial statements, included within the Annual Report and Financial Statements (the “Annual Report”), which 
comprise: the Consolidated statement of financial position as at 31 December 2022; the Consolidated statement of profit and loss; 
Consolidated statement of comprehensive income; Consolidated statement of changes in equity and Consolidated statement of cash 
flows for the year then ended; and the notes to the financial statements, which include a description of the significant accounting policies.

Basis for opinion
We conducted our audit in accordance with International Standards on Auditing (UK) (“ISAs (UK)”) and applicable law. Our responsibilities 
under ISAs (UK) are further described in the Auditors’ 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 remained independent of the company in accordance with the ethical requirements that are relevant to our audit of the financial 
statements in the UK, which includes the Financial Reporting Council’s (“FRC”) Ethical Standard, as applicable to listed public interest 
entities in accordance with the requirements of the Crown Dependencies’ Audit Rules and Guidance for market-traded companies, and 
we have fulfilled our other ethical responsibilities in accordance with these requirements.

Material uncertainty related to going concern
In forming our opinion on the financial statements, which is not modified, we have considered the adequacy of the disclosure made in 
note 2 to the financial statements concerning the Group’s ability to continue as a going concern. In assessing going concern the Directors 
have prepared a severe but plausible downside scenario which forecasts that delivery of existing and future sales contracts during 2024 
may not be at anticipated positive gross margins and may be delayed beyond June 2024. Under this scenario the Group would exhaust 
all available cash by April 2024 and it will be necessary to raise further funding within the next 12 months in order to continue trading and 
deliver on the strategic objectives. No such funding is committed as at the date of approval of the financial statements These conditions, 
along with the other matters explained in note 2 to the financial statements, indicate the existence of a material uncertainty which may 
cast significant doubt about the Group’s ability to continue as a going concern. The financial statements do not include the adjustments 
that would result if the Group were unable to continue as a 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:

 obtaining future cash flow forecasts, covering base case and a severe but plausible downside case, for a period of at least 12 
months from the date of approval of the financial statements. We assessed the forecast assumptions used in the base and severe 
but plausible downside scenarios;
 review of past forecasting accuracy by the directors;
 testing the mathematical accuracy of the forecasts;
 corroborating the forecast budgeted revenue with confirmed sales orders or revenue pipeline of the Group;
 comparing the assumptions used within the going concern model to the board approved budgets and business plans.
 corroborating the starting cash position at the beginning of the going concern period;
 reviewing and evaluating management’s sensitivities and performing additional sensitivity analysis over key assumptions in the 
model in order to assess the potential impact of a range of possible outcomes; and
 reading the disclosures in the financial statements and checking these were consistent with the Group’s plans for future fundraising 
and the Group’s current funding position.

Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this 
report.

Our audit approach
Context
Invinity Energy Systems plc is an independent, Jersey incorporated company. Its key subsidiaries are based in the UK, Canada and 
United States of America. The principal activities of the company and its subsidiaries relate to the manufacture and sale of vanadium 
flow battery systems plus associated installation, warranty and other services. Its manufacturing and assembly sites are located in the 
UK and Canada.

Overview
Audit scope

 We  conducted  full  scope  audits  on  four  components  and  the  audit  of  specified  balances  and  classes  of  transactions  on  one 
component. The scope of work at each component was determined by its contribution to the Group’s overall financial performance 
and its risk profile.
 We engaged our network firm in Canada to perform the audit procedures for components based in the United States of America and 
Canada. The work on the other components was performed by the UK firm.

  The components where audit work was performed accounted for approximately 99% of total assets.

Key audit matters
  Material uncertainty related to going concern.
  Accounting for the Riverfort and YA II PN Ltd arrangement.
  Completeness of Onerous Contracts Provision.

Impairment of Goodwill.

Materiality
  Overall materiality: £530,850 (2021: £650,000) based on 1% of Total Assets.
  Performance materiality: £398,000 (2021: £487,500).

The scope of our audit
As part of designing our audit, we determined materiality and assessed the risks of material misstatement in the financial statements.

Key audit matters
Key audit matters are those matters that, in the auditors’ professional judgement, were of most significance in the 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) 
identified by the auditors, 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, and any comments we make on the results of our procedures 
thereon, 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.

In addition to going concern, described in the Material uncertainty related to going concern section above, we determined the matters 
described below to be the key audit matters to be communicated in our report. This is not a complete list of all risks identified by our audit.

Accounting  for  the  Riverfort  and  YA  II  PN  Ltd  arrangement  is  a  new  key  audit  matter  this  year.  Warranty  provision  and  revenue 
recognition, which were key audit matters last year, are no longer included because of the reduced risk in relation to legacy products 
included within the warranty provision and the reduced risk of error in revenue recognition. Otherwise, the key audit matters below are 
consistent with last year.

Key audit matter 

How our audit addressed the key audit matter

Accounting for the Riverfort and YA II PN Ltd arrangement 
In December 2022 the Group entered into a $10m funding 
arrangement with Riverfort Global Opportunities and YA II PN 
Ltd (‘the noteholders’) of which $2.5m (£1.9m) had been drawn 
down by the balance sheet date. The initial drawdown included 
an issuance of warrants and the terms of the financing include a 
number of settlement features. 2,700,038 shares were issued to 
the noteholders as part of the arrangement.

We focused on this area due to the complexity in valuing the 
issued warrants and the settlement features of the contract. 
There was also judgement involved in identifying any embedded 
derivatives within the arrangement and anything which would 
meet the definition of an equity instrument. 

Refer to Notes 9, 25 and 29 for further details.

Completeness of Onerous Contracts Provision  
At the balance sheet date the Group has an onerous contract 
provision of £1.6m (2021: £4.9m). The onerous contract provision 
relates to 4 contracts.

We have focused on the completeness of this provision as 
determining the appropriate provision for contracts that are, 
or are expected to become, loss making requires a significant 
level of judgement. The calculation of the provision will require 
identification of the costs expected to be incurred and the 
benefits expected to be derived from individual contracts, 
including new contracts entered into in the period.

Refer to Note 21 for further details.

In  testing  the  accounting  for  the  funding  arrangement  we 
performed the following:

 We obtained the signed agreement with the noteholders and 
assessed the completeness of management’s assessment of 
the accounting for the terms of the agreement;
 Obtained management’s accounting paper detailing their 
assumptions and conclusions in relation to the accounting 
for the terms of the agreement. We challenged management 
on their conclusions against the requirements of IAS 32 and 
IFRS 9 particularly in relation to the issue of shares as part of 
the arrangement;
 Utilised PwC valuation experts to test management’s 
assumptions used in the valuation of the warrants and the 
derivatives;
 Confirmed the issuance of shares and warrant; and
 Evaluated the disclosures in the financial statements.

Based  on  work  performed  we  identified  no  matters  that  would 
suggest management’s assessment of the funding arrangement 
were materially misstated.

In testing the completeness of the onerous contract provision we 
performed the following:

 Obtained the complete list of contracts signed with customers 
to check if an onerous contract provision had been 
recognised or at least considered for each one;
 Obtained management’s onerous contract provision 
calculation and tested the constituent parts to management’s 
assumptions and corroborating evidence. Part of this test was 
to assess whether or not what was recognised was sufficient 
in light of the evidence obtained;
 Considered losses made on contracts to date and compared 
this to the calculated forecasted losses on contracts to identify 
any inconsistencies between future contracts with previous 
contracts and corroborating managements explanations for 
any change in the expected costs;
 For contracts identified where there was no provision we 
obtained corroborating evidence to support the expected 
costs for delivering these contracts and compared that to the 
expected revenue under the contract; and
 Verified the adequacy of relevant disclosures in the Group 
financial statements.

Based on work performed we identified no indicators that would 
suggest management’s assessment was materially misstated.

Key audit matter 

How our audit addressed the key audit matter

Impairment of Goodwill 
The Group holds goodwill of £23.9m. IAS 36 Impairment of 
assets requires an annual impairment assessment to be carried 
out for all indefinite life intangibles (goodwill) and whenever there 
are any indications of impairment for all other assets.

We focused on this area due to the material nature of the goodwill 
and given that the Group is currently incurring losses, there is a 
risk that the value of goodwill may not be recoverable.

Management has determined the recoverable amount of the 
relevant cash generating unit as at 31 December 2022 based on 
fair value less costs of disposal (in line with the approach adopted 
in 31 December 2021). 

Refer to note 15 for further details.

In auditing the impairment assessment we performed the following: 

 We considered the appropriateness of using the fair value 
less costs to sell approach; 
 We corroborated the share price at the balance sheet date 
and checked the accuracy of the market capitalisation 
calculation; 
 Assessed the inclusion of all appropriate assets and liabilities 
in the cash generating unit carrying value calculation and 
agreed that all relevant balances had been included; and 
 Verified the adequacy of relevant disclosures in the Group 
financial statements.

Based on the work performed, we determined that the 
assumptions used, and the approach taken, were reasonable. 
The recoverability of the goodwill is interlinked with the going 
concern assumption therefore the recoverability of the asset is at 
risk should the group not continue as a going concern.

How we tailored the audit scope
We tailored the scope of our audit to ensure that we performed enough work to be able to give an opinion on the financial statements 
as a whole, taking into account the structure of the Group, the accounting processes and controls, and the industry in which it operates.

The Group has one segment and cash generating unit, the group has two manufacturing and assembly locations in the UK and Canada. 
The accounting and financial reporting functions are also based in these two regions.

Our Group scoping was based on total assets within each component. We identified four components (the company, Invinity Energy 
(UK) Limited, Invinity Energy Systems (Canada) Corporation and Invinity Energy Systems (US) Corporation) which comprised a high 
proportion of total Group assets which required an audit of their complete financial information. One other component was subject to 
procedures over the provisions and contract liabilities financial statement line item level to obtain sufficient coverage.

The  audit  work  was  performed  by  the  Group  engagement  team  based  in  the  UK  and  component  auditors  based  in  Canada.  We 
maintained regular communication and conducted formal interim and year-end conference calls with the component team, as well as 
reviewing their audit work and reports to us.

Together  the  above  scoping  gave  appropriate  coverage  of  all  material  balances  at  a  Group  level.  On  a  consolidated  basis,  these 
provided coverage of 99% of total assets.

The impact of climate risk on our audit
Our audits considered the impact of climate change. As part of our audit, we made enquiries with management to understand the 
process adopted to assess the extent of the potential impact of climate risk on the Group’s financial statements and to support the 
disclosures made in the Sustainability section in the Strategic Report. We also read the Group’s governance process in response 
to climate risk. Using our knowledge of the business, we focused our work on how the impact of climate commitments made by the 
Group would impact the assumptions within the discounted cash flows prepared by management that are used in the Group’s going 
concern assessment. We challenged the completeness of management’s climate impact assessment by reading the external reporting 
made by management as well as internal climate plans and Board minutes. We also considered the completeness of the impact on 
financial statement line items by comparing management’s assessment of the impact of climate risk, including the potential impact on 
the underlying assumptions and estimates as outlined in the basis of preparation in note 2 to the Group financial statements.

Materiality
The scope of our audit was influenced by our application of materiality. We set certain quantitative thresholds for materiality. These, 
together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our audit 
procedures on the individual financial statement line items and disclosures and in evaluating the effect of misstatements, both individually 
and in aggregate on the financial statements as a whole.

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

Overall Group materiality 

£530,850 (2021: £650,000).

How we determined it 

1% of Total Assets

Rationale for benchmark applied 

 We believe that total assets is an appropriate measure for the Group given the current stage  
of development of the business and products.

For each component in the scope of our group audit, we allocated a materiality that is less than our overall group materiality. The range 
of materiality allocated across components was £224,000 to £450,000. Certain components were audited to a local statutory audit 
materiality that was also less than our overall group materiality.

We use performance materiality to reduce to an appropriately low level the probability that the aggregate of uncorrected and undetected 
misstatements exceeds overall materiality. Specifically, we use performance materiality in determining the scope of our audit and the 
nature and extent of our testing of account balances, classes of transactions and disclosures, for example in determining sample 
sizes. Our performance materiality was 75% (2021: 75%) of overall materiality, amounting to £398,000 (2021: £487,500) for the Group 
financial statements.

In determining the performance materiality, we considered a number of factors – the history of misstatements, risk assessment and 
aggregation risk and the effectiveness of controls - and concluded that an amount in the middle of our normal range was appropriate.

We agreed with those charged with governance that we would report to them misstatements identified during our audit above £25,000 
(2021: £32,500) as well as misstatements below that amount that, in our view, warranted reporting for qualitative reasons.

REPORTING ON OTHER INFORMATION
The other information comprises all of the information in the Annual Report other than the financial statements and our auditors’ report 
thereon.  The  directors  are  responsible  for  the  other  information.  Our  opinion  on  the  financial  statements  does  not  cover  the  other 
information and, accordingly, we do not express an audit opinion or any form of assurance thereon.

In connection with our audit of the financial statements, 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 audit, or otherwise 
appears  to  be  materially  misstated.  If  we  identify  an  apparent  material  inconsistency  or  material  misstatement,  we  are  required  to 
perform procedures to conclude whether there is a material misstatement of the financial statements or a material misstatement of the 
other information. 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 based on these responsibilities.

Strategic report and Directors’ Report
In our opinion, based on the work undertaken in the course of the audit, the information given in the Strategic report and Directors’ 
Report for the year ended 31 December 2022 is consistent with the financial statements and has been prepared in accordance with 
applicable legal requirements.

In light of the knowledge and understanding of the Group and its environment obtained in the course of the audit, we did not identify any 
material misstatements in the Strategic report and Directors’ Report.

RESPONSIBILITIES FOR THE FINANCIAL STATEMENTS AND THE AUDIT
Responsibilities of the directors for the financial statements
As explained more fully in the Statement of the Directors’ responsibilities, the directors are responsible for the preparation of the financial 
statements in accordance with the applicable framework and for being satisfied that they give a true and fair view. The directors are also 
responsible for such internal control as they 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 Group’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 Group or to cease operations, or have no realistic alternative but to do so.

Auditors’ 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  auditors’  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.

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.

Based on our understanding of the Group and industry, we identified that the principal risks of non-compliance with laws and regulations 
related  to  employment  law,  and  we  considered  the  extent  to  which  non-compliance  might  have  a  material  effect  on  the  financial 
statements. We also considered those laws and regulations that have a direct impact on the financial statements such as Companies 
(Jersey) Law 1991 and tax legislation. We evaluated management’s incentives and opportunities for fraudulent manipulation of the 
financial statements (including the risk of override of controls), and determined that the principal risks were related to manipulation of 
financial results (such as revenue) and potential management bias in accounting estimates to improve the performance of the Group. 
The Group engagement team shared this risk assessment with the component auditors so that they could include appropriate audit 
procedures in response to such risks in their work. Audit procedures performed by the Group engagement team and/or component 
auditors included:

  Evaluation of the design effectiveness of management’s controls designed to prevent and detect irregularities;

 Inquiries with the Board of Directors and Chief Financial Officer, including consideration of known or suspected instances of non-
compliance with laws and regulations and fraud;
 Review of board minutes;
 Challenging assumptions made by management in its significant accounting estimates, in particular in relation to impairment of 
intangible assets, provision for warranty, inventory and onerous contracts; and
 Identifying  and  testing  the  validity  of  journal  entries,  in  particular  any  journal  entries  posted  with  unusual  revenue  account 
combinations.

There  are  inherent  limitations  in  the  audit  procedures  described  above.  We  are  less  likely  to  become  aware  of  instances  of  non-
compliance with laws and regulations that are not closely related to events and transactions reflected in the financial statements. Also, 
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 or intentional misrepresentations, or through collusion.

Our  audit  testing  might  include  testing  complete  populations  of  certain  transactions  and  balances,  possibly  using  data  auditing 
techniques. However, it typically involves selecting a limited number of items for testing, rather than testing complete populations. We 
will often seek to target particular items for testing based on their size or risk characteristics. In other cases, we will use audit sampling 
to enable us to draw a conclusion about the population from which the sample is selected.

A further description of our responsibilities for the audit of the financial statements is located on the FRC’s website at: www.frc.org.uk/
auditorsresponsibilities. This description forms part of our auditors’ report.

Use of this report
This report, including the opinions, has been prepared for and only for the company’s members as a body in accordance with Article 
113A of the Companies (Jersey) Law 1991 and for no other purpose. We do not, in giving these opinions, accept or assume responsibility 
for any other purpose or to any other person to whom this report is shown or into whose hands it may come save where expressly agreed 
by our prior consent in writing.

OTHER REQUIRED REPORTING

COMPANIES (JERSEY) LAW 1991 EXCEPTION REPORTING
Under the Companies(Jersey) Law 1991 we are required to report to you if, in our opinion:

 we have not obtained all the information and explanations we require for our audit; or
 proper accounting records have not been kept by the company or proper returns adequate for our audit have not been received from 
branches not visited by us;
 the company financial statements are not in agreement with the accounting records and returns.

We have no exceptions to report arising from this responsibility.

NOTES

(forming part of the consolidated historical financial information)

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 listed 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 Summary of significant 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
In assessing whether the Group has the ability to continue as a going concern the Directors have modelled a base cash flow forecast for a 
period up to 31 December 2024. The Directors have prepared a base case scenario that assumes the 14.5m Short-Term warrants originally 
granted in 2021 (“Short-Term Warrants”), the terms of which are proposed to be amended as set out below are exercised before June 2024. 
Under this scenario the Group would expect to remain cash positive for the period up to 31 December 2024 assessed for going concern 
purposes. The forecast does indicate that the Group would move into negative cash shortly after the period assessed for going concern as 
a result of working capital investment on future sales. The Group would defer any working capital investment if it were to result in exhausting 
all cash. This forecast is also based on delivering existing signed sales contracts during 2023 as per forecast gross margins and existing and 
future sales contracts during 2024 at anticipated positive gross margins. The Directors recognise there is a risk that the Short-Term Warrants 
will not be exercised if they are not ‘in the money’ before the expiry date and given it is not at the discretion of the Group. 

The Directors have also prepared an alternative ‘adjusted base case’ scenario which does not include the exercise of the Short-Term 
Warrants but also adjusts forecasted costs. The Directors have a plan to adjust costs in a scenario where it does not look like the Short-
Term Warrants will be exercised. This plan includes the following:

   Non-payment or delayed payment of forecasted bonuses;
   No increase or delayed increase in salaries across the Group;
   Delayed recruitment of additional headcount; and
   Reduction in planned increase in research and development expenditure;

Under the adjusted base case the Group would expect to remain cash positive for the period up to 31 December 2024 assessed for 
going concern purposes. Therefore the Directors believe it is appropriate to prepare the accounts on a going concern basis. 

The Short-Term Warrants were initially granted in 2021 with an exercise price of 150p and an expiry date of 15 September 2022. On 
31 August 2022, the holders of the Short-Term Warrants agreed at a general meeting of Short-Term Warrant holders to amend the 
expiry date of the Short-Term Warrants to 15 September 2023. The Company is now planning to seek the approval of Warrant holders 
at a general meeting, notice of which will be given shortly, to make the following amendments to both the Short and Long-Term Warrants. 
The Company intends to seek approval to amend the Short-Term Warrant subscription period to 16 December 2023 (the Long-Term 
warrant subscription period will remain unchanged at 16 December 2024) and amend the exercise prices of the Short and Long-Term 
warrants to 50p and 100p respectively. There can however be no certainty that such a change in the terms will be approved. 

In assessing going concern the Directors have also prepared a severe but plausible downside scenario which forecasts delivery of 
existing and future sales being made during 2024 being delayed beyond June 2024 and forecasted margins not being achieved. Under 
this scenario the Group would exhaust all available cash by April 2024 and it will be necessary to raise further funding within the next 12 
months in order to continue trading and deliver on the strategic objectives. 

55

Annual Report and Financial Statements 2022UK  /  U.S.  /  CANADA  /  AUSTRALIAINTRODUCTIONSTRATEGIC REPORTGOVERNANCEFINANCIAL STATEMENTSInvinity Energy Systems plcNOTES

(forming part of the consolidated historical financial information)

The Directors are in the process of evaluating potential additional funding options from potential strategic investors but no such funding 
is committed as at the date of approval of these financial statements. The Group has been, and continues in, active discussions with a 
number of identified strategic investors and is confident that it will be able to conclude an equity investment from one or more of such 
parties within the period up to 31 December 2024 assessed for going concern purposes. The Directors also note that the Company 
concluded an initial strategic investment from Everbrite Technology Co., Ltd. for £2.5 million in March 2023 which gives them confidence 
that the Company is capable of attracting further strategic investment.

Due to the uncertainty in relation to obtaining additional funding this indicates the existence of a material uncertainty that may cast 
significant doubt about the Group’s ability to continue as a going concern. 

The financial statements do not include the adjustments that would result if the Group were unable to continue as a going concern. 

In addition to the issues discussed above, the directors have also reviewed other varying, and wide-ranging information relating to both 
present and future conditions when reaching their conclusion regarding going concern. These included the:

  operational performance of the Company’s products delivered to customer sites to date;
 value of contracts signed for delivery in 2023 and 2024;
 growing sales pipeline of 2,470.3 MWh in May 2023 vs 686.2 MWh in May 2022; 
 growing opportunities presented by the emergent energy storage market;  
 growing levels of Government engagement and support in the three key markets; and
 positive discussions with potential strategic partners regarding making an equity investment into the Company.

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 GBP 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 operations
Subsidiaries of the Company that are based in countries other than the UK or Jersey 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 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 month-end rate for each month during the year.

NOTES

(forming part of the consolidated historical financial information)

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.

Investments in associates and joint arrangements
Associates are entities where the Company can exert significant influence but is not able to exercise control.

Joint arrangements may be incorporated, where an entity exists, or may be unincorporated, where the venture or joint operation is 
governed by contract or other arrangement between two or more parties. The Company is not currently party to any unincorporated 
joint arrangements.

The Group accounts for its interests in associates and incorporated joint ventures using the equity method of accounting where the 
relevant investment is initially recorded at the cost to acquire the interest. After initial recognition, the Group recognises its share in the 
post-acquisition income and expenses of the associate in the statement of profit and loss with a corresponding increase (for income) or 
decrease (for losses) in the carrying value of the investment in the associate.

Dividends received by the Company from an associate are treated as a reduction in the carrying value of the associate (as its net assets 
have reduced by it giving the dividend) and income for the Group (as its net assets have increased by receiving the dividend).

The Group assesses the carrying value of associates for impairment at each reporting period end or at any other time where there is an 
indication that an impairment may exist. Where there is an indication of impairment of an investment, the Group assesses if an actual 
impairment loss exists by comparing the carrying value of the investment to its recoverable amount which is the lower of its fair value 
less cost to sell or its value in use.

Fair value less costs to sell is determined by reference to the proceeds that could be expected to be received should the interest in the 
associate be sold less the costs of doing so. Value-in-use is typically calculated by reference to the value of the discounted cash flows 
expected to be received from the associate.

Where there is a deficit of recoverable value as compared to the carrying value of the investment then an impairment loss is recognised 
in the consolidated statement of profit and loss in the amount of the calculated deficit. The carrying value of the investment in the 
associate is also reduced by a corresponding amount.

Acquisitions
The Group allocates the purchase consideration given in respect of the acquisition of a subsidiary to the assets acquired and liabilities 
assumed based on an assessment of their individual fair values at the date of acquisition. Any excess of the cost of the acquisition over 
the fair value of assets acquired and liabilities assumed in the business combination is recognised as goodwill.

The assessment of fair value is made by comparing the discounted value of the future net cash flows expected to be generated from 
the CGU to which the goodwill has been allocated to the net book value of the assets and liabilities of that CGU including the allocated 
goodwill. Where a deficit of discounted cash flows compared to the carrying value of the CGU’s net assets and allocated goodwill exists, 
the goodwill is reduced to its recoverable amount with a corresponding amount recognised as an impairment charge in profit or loss. 
A corresponding reduction is made to the carrying value of goodwill and then to the net assets of the CGU if goodwill is insufficient to 
absorb the loss. Goodwill may also be tested for impairment under the fair value less costs to sell method where the recorded value of 
goodwill is compared to the market or value of the Company calculated by reference to its share price.

Any such impairment loss is recognised in profit and loss in the period in which it is identified. Impairment losses related to goodwill 
cannot be reversed in future years.

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.

Discontinued operations
A discontinued operation is a component of the Company’s business that represents a separate major line of business or geographical 
area of operations that has been disposed of or is held for sale. Classification as a discontinued operation occurs on actual disposal or 
earlier if the operation meets the criteria to be held for sale. When an operation is classified as a discontinued operation, the comparative 
consolidated statement of profit and loss is restated as if the operation had been discontinued from the start of the comparative period.

Disposal of subsidiaries
Transactions that result in the loss of control of a subsidiary are accounted for as disposals. The previously consolidated assets and 
liabilities and the carrying amount of any non-controlling interests in the subsidiary are derecognised. Any retained interest in the former 
subsidiary is recognised at its fair value at the date when control is lost. A gain or loss on disposal is recognised as the difference 
between the fair value of the consideration received together with the fair value adjustment made in respect of any retained interest in 
the subsidiary as offset by the carrying value of the assets and liabilities derecognised. Any gains or losses of the disposed entity that 
were previously recognised in other comprehensive income or loss and that require to be recycled to profit or loss also form part of the 
gain or loss on disposal.

New standards, amendments and interpretations effective and adopted by the Group in 2022
Amendments to existing standards previously issued by the IASB with effective dates during the year ended 31 December 2022 are 
summarised below. There was no effect on the Group’s consolidated financial statements for the year ended 31 December 2022 as a 
result of the adoption of these amendments.

Amendment to ‘IFRS 16 Leases’
On 28 May 2020, the IASB issued an amendment to the standard related to the treatment of rent concessions given by lessors in relation 
to COVID-19. The Group did not receive any rent concessions related to COVID-19 that would require consideration of the amendment 
to IFRS 16 and, accordingly, the amendment had no impact on the consolidated financial statements for the years ended 31 December 
2021 or 2022.

Amendments to ‘IFRS 3 Business Combinations’
On 2 July 2021, the IASB published amendments to references to the 2018 version of the Conceptual Framework for Financial Reporting. 
The amendment was effective on or after 1 January 2022. 

Amendments to ‘IAS 16 Property, Plant and Equipment – Proceeds before Intended Use’ 
On 2 July 2021, the IASB published an amendment to IAS 16 which prohibits deducting from the cost of an item of property, plant and 
equipment the proceeds from selling items produced before that asset is available for use. The Company does not deduct revenue from 
the cost of assets before they are available for use and therefore, there is no impact on the Group financial statements for the year ended 
31 December 2022. The amendment was effective on or after 1 January 2022

Amendment to ‘IAS 37 Provisions, contingent liabilities and contingent assets’
On 2 July 2021, the IASB published an amendment which requires the provision in respect of an onerous contract to also include an 
assessment of the indirect costs, such as production overhead or indirect labour, that are expected to be incurred in servicing a contract 
considered to be onerous. The amendment was effective on or after 1 January 2022.

Annual Improvements 2018-2020

 Improvement to ‘IFRS 1 First-time Adoption of IFRS’ (effective for periods beginning on or after 1 January 2022)
Improvement to ‘IFRS 9 Financial Instruments’ (effective for periods beginning on or after 1 January 2022)
Improvement to illustrative examples to ‘IFRS 16 Leases’ 
Improvement to ‘IAS 41 Agriculture’ (effective for periods beginning on or after 1 January 2022)

New standards and interpretations not yet adopted 
Certain new accounting standards and interpretations have been published that are not mandatory for 31 December 2022 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 summarized below. 

IAS 1 Classification of Liabilities as Current or Non-Current (effective for periods beginning on or after 1 January 2024);
 IAS 1 and IFRS Practice Statement 2 Disclosure of Accounting Policies from significant to material (effective for periods beginning 
on or after 1 January 2023);
IAS 8 Amendments to Definition of Accounting Estimates (effective for periods beginning on or after 1 January 2023);
 IAS 12 Deferred Tax related to Assets and Liabilities arising from a Single Transaction (effective for periods beginning on or after  
1 January 2023); and
IFRS 17 Insurance Contracts (effective for periods beginning on or after 1 January 2023).

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.

NOTES

(forming part of the consolidated historical financial information)

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.

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 in 2024 and insufficient Short-
Term Warrants being exercised. Refer to ‘Basis of preparation’ for details of the going concern analysis performed and the Directors’ 
conclusions regarding going concern.

Notwithstanding the material uncertainty articulated in relation to the basis of preparation, 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 – examples include the delivery of equipment. 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 equipment or, more likely, 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.

The assessment of what constitutes a performance obligation can be complex and requires judgment. Revenue is only recognised for 
each performance obligation under a contract when that performance obligation, bundled or otherwise, is satisfied. The requirement to 
bundle combinations of goods and/or services together as a single performance obligation could delay the timing of revenue recognition 
where the separate promises comprising the performance obligation are delivered sequentially.

Key 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.

59

Annual Report and Financial Statements 2022UK  /  U.S.  /  CANADA  /  AUSTRALIAINTRODUCTIONSTRATEGIC REPORTGOVERNANCEFINANCIAL STATEMENTSInvinity Energy Systems plcNOTES

(forming part of the consolidated historical financial information)

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 10% increase in the number of warranty claims or a 10% increase in the cost to remedy warranty issues would have a corresponding 
effect on warranty cost in a given period.

Refer to note 21, contract related balances.

Provision for legacy products
Management has elected to provide ongoing maintenance for certain legacy contracts not otherwise covered under warranty. Management 
has determined that it is necessary to provide for the costs of this ongoing maintenance or to provide for outright decommissioning.

Refer to note 21, contract related balances.

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. Previously, assessment of the unavoidable costs under a contract only required direct 
costs such as parts and labour to be considered. 

An amendment to ‘IAS 37 Provisions, contingent liabilities and contingent assets’ was published in May 2020 and requires the provision 
in respect of an onerous contract to also include an assessment of the indirect costs, such as production overhead or indirect labour, that 
are expected to be incurred in servicing a warranty claim. The Company elected to early adopt the amendment as of 1 January 2020 
and therefore has applied the provisions of the standard in the current and prior years.

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.

Refer to note 21, contract related balances.

Share based payments, warrants and employee options
The Company determines the fair value of share-based payments and employee options using a Black-Scholes methodology. Black-
Scholes uses certain assumptions to determine fair value including measures of share price volatility, expected conversion or exercise 
rates and levels of employee retention, among others.

In estimating the value of future share price volatility, a key input of the Black-Scholes methodology, the Company uses historic data 
relating to its share price. As the short and long-term warrants are listed, and therefore can be publicly traded, this provides an alternative 
arms-length determination of fair value.

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 Development Officer and Interim Chief Financial 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.

3 Accounting policies
Revenue
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. Control is usually considered to 
have transferred to a customer on delivery of equipment to the customer’s site of operations or when title to the equipment is transferred 
to the customer (if stored offsite). 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. 

The Group generates revenue from the sale of battery storage systems and related hardware and services. The main portion of sales 
is derived from contractual arrangements with customers that have multiple elements (or performance obligations), those elements 
usually being the sale of battery systems, system related options, installation, and extended warranties. 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.

In addition, under the terms of its contracts for sale, the Group may be responsible for 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. The related costs incurred by the Group for 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 Company 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 Company. 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 Company’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 (for example, the requirement for an employee to save).

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 as deductible temporary differences only where it is probable that taxable profits will be generated 
against which the carrying value of the deferred tax asset can be recovered. Deductible temporary differences exist where there is a 
difference in the timing of the recognition of an item of income or expense between the statement of profit and loss and the calculation 
of taxable profit or loss (a temporary difference).

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, associates and interests in joint operations. 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 in a transaction 
that is not a business combination 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.

NOTES

(forming part of the consolidated historical financial information)

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.

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.

Goodwill arising is recognised as an intangible asset in the balance sheet and is subject to annual reviews for impairment. Goodwill is 
written off where circumstances indicate that the recoverable amount of the underlying CGU may no longer support the carrying value of 
the goodwill. 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.

In testing for impairment, goodwill recognised on business combinations is allocated to the Group of CGUs representing the lowest level 
at which it will be monitored. 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.

The recoverable amount of a CGU or a group of CGUs is based on the higher of its assessed fair value less costs of disposal or its 
value-in-use. Value-in-use is calculated by reference to the expected future cash flows from the CGU, after discounting to take account 
of the time value of money. Fair value less costs to sell can be based on a similar cash flow measure adjusted for disposal costs or can 
be estimated by reference to similar comparable reference transactions.

Because the Company is listed, fair value can also be assessed by reference to the Company’s market capitalisation. Where cash flows 
are used, they are risk weighted to reflect an assessment of future commercial success.

The key assumptions in assessing cash flows relate to the ability of the Company to develop existing markets and applications and 
to establish new markets and applications for the sale and use of its battery systems. Prospective cash flows are also sensitive to the 
Company’s ability to realise economies of scale as market penetration grows.

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.

NOTES

(forming part of the consolidated historical financial information)

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 asset is brought into use. Work-in-progress assets are not depreciated until they are brought into 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.

(forming part of the consolidated historical financial information)

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 Company or 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. 

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 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.

The increase in a provision as the discount rate unwinds due to the passage of time, is recognised in the statement of profit and loss as 
other items of operating income and expense.

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

(forming part of the consolidated historical financial information)

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 remaining lease term of less than 12 months at 1 January 2022 and leases related to low value assets with an annual 
lease cost of £3,500 or less.

The Group recognises these lease payments as an expense on a straight-line basis over the lease term.

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 and the costs 
that would be incurred in the marketing, selling and distribution of an item of inventory.

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
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.

A financial asset is recorded at amortised cost where it is expected to be held to maturity and the objective of the Group is to collect the 
contractual cash flows under the financial instrument based on specified contractual terms, including the timing of receipt of cash flows.

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

Financial asset 

Trade receivables and accrued income 
Other current assets 
Contract assets 
Cash and cash equivalents

(forming part of the consolidated historical financial information)

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 is recognised immediately in profit or loss and are included in other gains/(losses).

Cash and cash equivalents
Cash and cash equivalents include cash on hand, deposits held with financial institutions that can be called on demand together with 
other short-term, highly liquid investments with maturities of three months or less and are readily convertible to known amounts of cash.

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
A financial asset and a financial liability are offset and the net amount presented in the statement of financial position when, and only 
when, the Group:

  has a legally enforceable right to set off the recognised amounts; and

intends either to settle on a net basis, or to realise the asset and settle the liability simultaneously.

The Group maintains its principal production and assembly facilities in Bathgate, Scotland and Vancouver, Canada. These facilities 
include office space for design, sales and administrative teams. The Group also has offices, operations and management based in 
London, England and San Francisco, California.

The Group does not consider that the locations of its operations constitute geographic segments as they are managed centrally by the 
executive management team. The location of the manufacturing plants and business development activity is a function of time-zone 
when servicing customers both pre-sale and during product delivery. The geographic location of offices, facilities and management is 
not related to distinct markets or customer characteristics at the present time.

Significant customers and concentration of revenue
Revenue from contracts with customers was derived from three (2021: two) customers who each accounted for more than 10% of total revenue 
as follows:

Plans with non-standard performance conditions
Long-term incentive plan (LTIP) 
The LTIP for Directors and employees was approved by the Board in 2008 and entitled Directors and employees to receive equity settled 
payments annually based on the achievement of certain market and non-market performance conditions.

The LTIP is now closed. At the end of the year, there were 15,000 (2021: 15,000) options vested and exercisable at €0.50 per share.

CAMCO 2006 executive share plan (the plan)
The plan was established in 2017 to make awards of shares up to an aggregate of 10% of the share capital of the Company over a 
period of ten years.

The plan is now closed. At the end of the year there were 68,127 (2021: 68,127) options vested exercisable at €0.50 per share.

redT 2018 plan
Options with non-standard performance conditions were also issued under the 2018 plan. At the end of the year there were 70,000 (2021: 
70,000) options vested and exercisable at 400p per share.

Plans with standard performance conditions
The primary share plan that remains outstanding at 31 December 2022 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.

In the year ended 31 December 2020 the Board approved the expansion of awards to be made under the 2018 plan with grants expected 
to be made more frequently going forward and to a potentially wider group of employees. The intention of the increase in frequency 
and quantity of employee share options granted was to incentivise and to better align employee compensation with shareholder return.

Options issued to legacy Avalon employees at the merger date
Following the merger transaction, 1,432,000 options were granted to legacy Avalon employees to replace options held by them in the 
former Avalon employee share plan. 

Parallel options issued
In  addition,  certain  legacy  redT  options  were  reissued  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.

Warrants issued in the period or outstanding
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 2022, the Company had 14,464,317 short-term warrants and 14,464,478 long-term warrants outstanding. 

Each short-term warrant gives the holder the right to subscribe for one new Ordinary Share at a price of 150 pence per Ordinary Share 
at any time from Second Admission until 15 September 2023. Each long-term warrant gives the holder the right to subscribe for one new 
Ordinary Share at a price of 225 pence per Ordinary Share at any time from Second Admission until 16 December 2024.

The warrants were admitted to trading on the Aquis Stock Exchange (AQSE) on 9 March 2022. There was no adjustment to the issue 
price in respect of the attached warrants and they have been deemed to have no fair value based on the price at which they are currently 
being 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 67.35 
pence per Ordinary Share until 14 December 2026.

Subsequent to year-end, the Company was required to amend the exercise price of these warrants to 32 pence, being the issue price of 
the Placing and Open Offer on 22 February 2023. 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.

Goodwill
All goodwill is tested annually for impairment. At 31 December 2022, 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 43.0 pence per share at that date. 
No impairment loss was identified in relation to goodwill. 

On 15 March 2023, the Company announced the results of a placing, open offer, and subscription. The fundraising was oversubscribed 
and together raised total proceeds of £23.0 million through placing of 72,012,592 new Ordinary Shares at 32.0 pence per share. 

The  closing  share  price  on  30  May  2023  was  35.5  pence,  giving  a  market  capitalisation  of  £67.8  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 2022.

1  In 2022, a lease on a right-of-use asset in South Africa was curtailed by five months. There was a corresponding decrease in the outstanding 
lease creditor and a gain on curtailment recognised in the consolidated statement of profit and loss in 2022. 

2  In 2021, a lease on a right-of-use asset in Canada was curtailed, with the termination date changing from June 2027 to June 2023. There was 
a corresponding decrease in the outstanding lease creditor and a gain on curtailment recognised in the consolidated statement of profit and 
loss in 2021.

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.

NOTES

(forming part of the consolidated historical financial information)

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.

The Company’s subsidiaries carry on business in other tax regimes where the corporation tax rate is not zero. At 31 December 2022, the Group 
had the following tax losses carried forward available for use in future periods:

United States of America

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.

In  March  2021,  the  UK  Government  announced  that  the  rate  of  Corporation  Tax  will  increase  from  19%  to  25%  on  profits  of  over 
£250,000, effective 1 April 2023. Profits below £50,000 will continue to be chargeable to Corporation Tax at 19% and profits between 
the two thresholds charged at the marginal rate of 26.5%. 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.

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.

21 Contract related balances
The Group has recognised the following assets and liabilities related to revenue from contracts with customers that are in progress at the 
respective year-ends:

Amounts due from customer contracts included in trade receivables 
Contract assets (accrued income for work done not yet invoiced)   
Contract liabilities (deferred revenue related to advances on customer contracts)

(6,138)

(5,142)

(3,135)

The amount of revenue recognised in the year that was included in contract liabilities at the end of the prior year was £428,417 (2021: 
£2,231,000).

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 ongoing maintenance for certain legacy products not 
otherwise covered under warranty. Management has determined that it is necessary to provide for the costs of this ongoing maintenance 
or to provide for outright decommissioning. 

Provisions in respect of legacy products are expected to unwind over the next two years when maintenance is either terminated or the 
products are decommissioned.

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, albeit receding, impact of COVID-19, 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 2023 and will therefore unwind during 
that year.

All trade and other 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 2022 was determined to be less than 1% of total sales (2021: 0%). An allowance for potential credit losses of 
£23,953 (2021: £nil) has been recognised.

Information about the Group’s exposure to interest rate, foreign currency and liquidity risks is included in Note 29. 

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. Following the redemption of the investment agreement any proceeds from the sale of the conversion shares 
are to be split 97% to the company and 3% to the Noteholders.

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 
capital raise.

Prepayment was at the Company’s option and carried a redemption premium of 10% paid to the Noteholders at the date of prepayment. 

The convertible notes balance was fully repaid by 31 March 2023 using funds from the 2023 capital raise. The warrants issued to the 
Noteholders were repriced to the price achieved in the 2023 capital raise of 32p per share.

See Note 32 for detailed events occurring after the report period.

During the year, 2,959,085 new shares were issued with a nominal value of £25,974. The total gross proceeds were £80,927 with the 
balance credited to the share premium account. Total costs of issuance were £82,442 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. 

In addition, the shares of the Company were admitted to trading on the AQSE Growth Market in the UK and the OTCQX Best Market 
in the U.S. during the year.

The holders of ordinary shares are entitled to receive dividends as may be declared from time to time and are entitled to one vote per 
share at meetings of the Company.

Share-based payment reserve
The share-based payment reserve comprises the equity component of the Company’s share-based payments charges.

Currency translation reserve
The translation reserve comprises foreign currency differences arising from the translation of the financial statements of foreign operations.

Other reserve
Other reserve comprises the portion of the consideration paid for redT energy Holdings (Ireland) Limited’s minority interests over the 
fair value of the shares purchased.

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 2022, 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 (2021: none).

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 2022 (2021: 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.

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.

Prior year sensitivity of profit or loss was restated to consistently use monetary working capital as basis for analysis.

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

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. 

Notwithstanding the above, 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.

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:

(forming part of the consolidated historical financial information)

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.

32 Events occurring after the report period
On 23 February 2023, the Company announced it had raised gross proceeds of £19 million through a placing of 59,375,000 new 
ordinary shares of €0.01 each and £2.5 million through subscription by Everbrite Technology Co., Ltd. of 7,812,500 new ordinary shares, 
both at an issue price of 32 pence per new ordinary share. 

The Company also offered to all qualifying shareholders the opportunity to participate in an open offer to raise up to £4 million at issue 
price. The open offer was made on the basis of: 2 open offer shares for every 19 ordinary shares held.

On 14 March 2023, the Company announced it had received valid acceptances from qualifying shareholders in respect of 4,825,092 
open offer shares, therefore raising an additional £1.5 million of proceeds.

As part of the placing and open offer, the Directors subscribed for new ordinary shares which raised gross proceeds of approximately 
£60,000 in aggregate.

The Company has therefore raised, in aggregate, gross proceeds of approximately £23 million through the placing, subscription and 
open offer.

In addition, on 3 March 2023, the Company announced it had entered into a repayment agreement to repay the outstanding drawn 
amount of the convertible loan facility with Riverfort Global Opportunities PCC Ltd and YA II PN Ltd (“Noteholders”). The Company has 
settled the outstanding drawn amount together with the redemption premium of 10% (US$208,107.53). 

Pursuant to the facility, on 14 December 2022 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. In accordance with the terms of the warrant instrument, the Company was required 
to  amend  the  exercise  price  of  these  warrants  to  32p,  being  the  issue  price  of  the  recently  announced  placing  and  open  offer.  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.

As part of the facility, 2,700,038 ordinary shares were issued to the Noteholders to effect initial conversions relating to the initial advance. 
Any shares held by Noteholders after the facility has been repaid will be sold with relevant net proceeds remitted to the Company. At 
3 March 2023, 1,779,640 of the Initial Shares are remaining and held by the Noteholders. 

The ongoing events in Ukraine have led to international macro-economic instability. The impact on sterling has fed through to increased 
input costs and these are expected to continue while the situation remains unresolved.
