resulting in a reduction of headcount of 40% and a lowering of the variable costs of the business. 

Executive Chairman, Iain Ross, commented: “During the last year the Company has undergone a complete 
transition including an organisational restructuring; a change in management and a strategic re-alignment, to 
create sustainable value for shareholders with the emphasis on the development, partnering and potential 
licensing of CustomEXTM, our proprietary drug delivery platform. During the year under review the underlying 
cost base has been reduced and resources re-aligned to meet the immediate needs of the business. I remain 
very excited about the Company’s potential as we are on course to generate validating data which would allow 
us to complete partnering and license deals in the coming year which will transform the Company.”

Executive Chairman’s Statement 

Dear Shareholders, 

Our immediate strategic focus remains primarily on our CustomEXTM Exosome Technology Platform, producing 
exosomes with unique tissue targeting capabilities to deliver a payload of choice to a preferred cell type. Our 
mission is, in collaboration with academic and industry partners, to develop novel exosome therapeutics for 
diseases with significant unmet needs. 

CustomEXTM provides a unique delivery mechanism for a variety of payloads including nucleic acids, proteins, 
and gene editing technologies. We use our conditionally immortalised induced pluripotent stem cell (CI-iPSC) 
platform to make allogeneic tissue cells of choice, which have the potential to produce exosomes with tissue 
specific targeting ability. Both platforms are supported by an extensive and proprietary intellectual property 
portfolio. 

Our overall strategic goal is to exploit the global drug delivery market opportunity by providing exosomes as 
a vector to facilitate the delivery of therapeutics. It is estimated that the supply of viral and non-viral vectors is 
worth c. $2.1 billion1 today increasing up to $3.9 billion1 by 2026 and there is considerable academic and 
industry interest in the development of next-generation delivery vectors such as exosomes. Over the past few 
years, peer companies have raised $403 million2 in support of exosome-based activities and secured exosome 
related license agreements with potential revenues in excess of $3 billion2. We believe our stem-cell derived 
exosomes  can  potentially  overcome  issues  such  as  tissue  specificity,  crossing  the  blood-brain  barrier  and 
unwanted immune activation, which have hampered first-generation drug delivery platforms. So, through the 
combination of our two proprietary platforms we are competitively well positioned to exploit this growing 
market opportunity.  

Financial highlights 
In January 2023, the Company undertook a restructuring of the business, reducing headcount by 40% and 
lowering variable costs of the business, with the latest forecasted cash runway now extending into mid-calendar 
year 2024. The full benefit of the cost savings from this restructuring will not be seen until financial year 2024. 
Revenue for the year was £0.5 million (2022: £0.4 million) related to income from partner funded development 
activities and royalty income. We also saw reduced operating costs of £7.6 million (2022: £11.6 million) primarily 
due to a reduction in clinical trial related costs following the strategic review in January 2022. This reduction 
was partly offset by additional investment made in the exosome technology platform.  

Net cash used in operating activities was £7.5 million (2022: £7.4 million). Cash used was higher than the loss 
for the year which is explained by changes in working capital and capital investment made to support exosome 
platform development. Cash, cash equivalents and bank deposits at 31 March 2023 were £7.2 million (31 March 
2022: £14.5 million). Loss for the year was £5.4 million (2022: loss of £9.7 million), the reduction being driven 
by lower costs and increased revenue as noted above. 

Corporate and organisational development 
There have been several senior leadership team changes over the last 12 months. In September 2022, the 
Company  announced  that  John  Hawkins  had  been  promoted  to  Chief  Financial  Officer  and  joined  the 
ReNeuron Board, Dr. Randolph Corteling assumed the role of Chief Scientific Officer, Suzanne Hancock was 
appointed as Chief Operations Officer and Simon Dew, an experienced business development professional 
with significant track record of dealmaking in the exosome filed, would be joining the Company as Chief 
Business Officer.  

In December 2022, Catherine Isted stepped down as Chief Executive Officer and Iain Ross was appointed as 
Executive Chairman. Subsequently the Company undertook a restructuring of the business with an internal 
operational re-alignment in line with the business needs resulting in a reduction of headcount of 40% and a 
lowering of the variable costs of the business.

Executive Chairman’s Statement 

continued

Professor Stefano Pluchino assumed the role of Chair of the new Scientific Advisory Board (SAB) combining 
working with ReNeuron with his academic work in Exosomes and Regenerative Neuroimmunology at the 
University of Cambridge. The new exosome focused SAB has also been established composed of leading 
academics and industry executives, Prof. Giuseppe (Beppe) Battaglia, Prof. Edit I Buzás, Prof. Dr. rer. nat. Bernd 
Giebel and Prof. Kenneth W. Witwer and chaired by Prof. Stefano Pluchino. This new SAB brings a world-class 
breadth of expertise across the extracellular vesicle (EV) field. Its role is to advise the Company on scientific 
matters relating to its exosome platform research and development strategy.  

Research & development 
In  FY22  the  Company’s  R&D  team  established  CustomEX™,  the  first  scalable,  consistent,  targeted  and 
customisable stem cell-derived exosome drug delivery platform. This unique exosome platform is based upon 
the exosomes produced from different stem cells having the unique cellular targeting properties of the stem 
cells from which the exosomes were produced. Proof-of-concept studies have determined unique in vitro 
targeting  and  delivery  characteristics  for  all  seven  exosome  populations  and  demonstrated  a  significant 
improvement in uptake and subsequent delivery of a therapeutic siRNA cargo using the CustomEX™ platform 
compared to current delivery methods and a HEK 293-derived exosome. 

Further  proof-of-concept  in  vitro  studies  are  ongoing  to  validate  the  benefits  observed  in  vitro  of  the 
CustomEXTM platform to deliver therapeutic cargoes 

To demonstrate the enhanced utility of the CustomEX™ drug delivery platform, the R&D team has made 
significant improvements to the loading of nucleic acid cargos. In-house optimisation and further modifications 
to the downstream manufacturing process has led to increases in exosome concentration and purity, leading 
to an approximate 30-fold increase in siRNA being associated with CustomEX™ exosomes.  In addition, further 
in  vitro  proof-of-concept  for  our  engineered  exosome  product,  Exo-BDNF  was  established  through  a 
collaboration with Cardiff University that demonstrated the products efficacy to improve retinal ganglion cell 
survival in a model of glaucoma.  

The Group’s iPSC platform continues to support the expansion of the CustomEX™ platform and following 
Dr Pell’s presentation at the 2nd iPSC derived Cell Therapy Summit in December, there is growing interest in 
the platform in its own right. ReNeuron’s iPSCs were developed from the Group’s conditionally immortalised 
CTX stem cell line. This immortalisation characteristic is retained by the iPSCs (conditionally immortalised iPSCs 
or CI-iPSCs), allowing subsequent cell lines to be rapidly developed that benefit from their highly stable and 
reproducible expansion. Investigation into the utility of CI-iPSCs continues with two groups at University College 
London (UCL), firstly investigating the potential use of CI-iPSCs to generate CAR-T / CAR-NK cells and secondly 
with a separate group at UCL investigating the ability to differentiate into Schwann cells for potential use in 
peripheral nerve damage repair. 

In July, ReNeuron negotiated and signed the CTX Technology Transfer Supplemental Terms Agreement with 
Fosun Pharma, underscoring Fosun Pharma’s continued commitment to the CTX stroke disability programme.  
The project to transfer both the CTX Drug Product and Working Cell Bank manufacturing processes and quality 
control  testing  know-how  to  Fosun  Pharma  has  continued  to  make  good  progress.  In  addition  to  the 
£320k  upfront  payment  received  in  January  2022  for  services  delivered  in  FY23,  ReNeuron  has  received 
approximately  a  further  £100k  for  supply  of  initial  CTX  working  cell  bank  vials  and  additional  ReNeuron 
resources and project related costs; with further milestone payments expected in accordance with defined 
project milestones. Under the Technology Transfer agreement there is potential for the Group to receive up to 
£5 million over the medium to long term, with further potential milestone payments of up to £74 million linked 
to the main license agreement signed in 2019. 

In 2022, Dr Corteling was a guest speaker at two international conferences where he presented, for the first 
time, the full breadth of the Group’s CustomEX™ exosome platform. Consisting of four distinct neural producer 
stem cell lines (cortical, striatal, hippocampal and mesencephalic), three non-neural stem cell lines (liver, retinal 
and pancreatic), and its conditionally immortalised induced pluripotent stem cell line (CI-iPSCs) which can be 
used to produce further exosome producer cell lines depending on the target required.

Outlook 
As of today, ReNeuron has seven proprietary, conditionally immortalised exosome producer stem cell lines. We 
believe that our catalogue of proprietary stem cells, from neural and non-neural tissue, differentiates us from 
competitors in the field and leads to a greater chance of success for optimised delivery of a payload to a 
particular target. The Company has years of experience and knowledge in the manufacture of consistent stem 
cell  banks  to  good  manufacturing  practice  (GMP),  including  two  investigation  new  drugs  (INDs),  and  is 
continuing to work with third parties to develop improvements in downstream processing and analytics.  

In summary, over the next 3-6 months the Company will continue to develop its exosomes platform, generating 
in vivo data exemplifying the cellular and tissue targeting capabilities of exosomes produced from its multiple 
conditionally  immortalised  producer  cell  lines  and  the  subsequent  functional  delivery  of  therapeutic 
payloads. Favourable  in vivo data will allow the Group to differentiate its exosome platform and progress 
ongoing  partnering  and  licensing  discussions.  The  Board  has  identified  a  number  of  potential  sources  of 
revenue and non-dilutive funding in order to maintain the business as a going concern and is confident it will 
be  able  to  conclude  third  party  transactions  and/or  issue  new  equity  as  required.  Such  transactions  will 
further strengthen and differentiate our exosomes platform, highlighting our potential leadership in the field. 

Finally, I would like to thank past and present members of the Board, Management team and staff for their 
continued  commitment  and  hard  work  throughout  what  has  been  a  tough  and  challenging  year.  I  would 
especially like to thank Catherine Isted for her contribution as CFO and latterly as CEO and to wish her well in 
the future.  

I look forward to an exciting and rewarding year ahead and would like to thank the shareholders for their 
continued support.

ReNeuron’s  stem  cell  derived  proprietary  exosome  technology  platform  CustomEX™  offers  a  delivery 
mechanism for a variety of potential payloads that could include siRNA, mRNA, proteins, small molecules and 
genes. 

What are exosomes? 
l      Naturally  occurring  biological  nano  particles  produced  by  every  cell  to  mediate  intercellular 

communication. 

l      Can encapsulate various biological molecules within their lipid bilayer membrane or within the lumen of 

the Exosome. 

l      Can be engineered to deliver drug cargos to target cells, offering an opportunity to treat diseases. 

The benefits of exosomes 
l      Proven ability to carry and deliver a variety of cargos including proteins and nucleic acids. 

l      Potential to deliver more than one bio-active cargo simultaneously. 

l      Target recipient cells via specific surface proteins that are determined by their cell of origin. 

l      Low or no immunogenicity, thereby evading immune detection. 

Current delivery mechanisms have limitations 
l      Viral vectors have been plagued by side effect issues and high costs, limitation on the type and size of 

cargo they can deliver. 

l      Lipid nanoparticles (LNPs) have no natural tissue and cell targeting capabilities with delivery therefore 

untargeted and mainly to the liver. 

l      Both have immunogenetic properties that can be problematic. 

CustomExTM: A customisable exosome platform 
l      Seven  proprietary conditionally  immortalised*  exosome  producer  stem  cell  lines  producing  unique 

exosome populations. 

l      ReNeuron’s iPSC platform allows production of exosomes that have the functional properties based on 

parent stem cells. 

l      Capable of delivering a variety of payloads including proteins and nucleic acids and the next generation 

for delivery of gene editing technologies. 

l      Data highlights increased uptake and delivery of payload when compared to a conventional HEK exosome 

approach. 

l      Our CustomExTM exosomes have distinct surface marker profiles (tropisms) enabling a greater tissue 

targeting capability. 

*Conditional immortalisation of stem cell exosome producer lines offers an elegant solution to not only 
consistently produce cell lines that are genetically stable and can be grown at scale, but also to produce a high 
yielding source of consistent exosomes for the delivery of complex drug modalities. The standard approach 
used by our competitors is to produce exosomes from a single generic cell line. A one-size-fits-all approach. 
A single cell line, giving rise to a single outcome.

Technology Overview

At ReNeuron, we have a portfolio of stem cell exosomes that have distinct properties. This allows us to choose 
the most appropriate exosome delivery vehicle, not only based upon its tissue targeting but also upon the 
specific requirements of the therapeutic payload in terms of the cellular compartment that the cargo needs to 
reach to achieve a therapeutic effect (i.e. the fluid that fills the cell (cytoplasm) for RNAi and the nucleus 
for DNA). 

The current portfolio of stem cell exosomes can also be rapidly expanded using ReNeuron’s proprietary CI-iPSC 
lines. Additional stem cell exosome producer lines from any cell lineage can be generated from our iPSCs if 
the specific exosome population does not already form part of our catalogue. 

EXOSOMES – The science in more detail 

Exosomes – a natural next-generation drug delivery vector 
Throughout  the  twentieth  century,  small  molecule  drugs  made  by  medicinal  chemists  drove  value  in  the 
pharmaceutical industry and comprised essentially all the world’s most innovative prescription medicines. As 
therapeutically  relevant  targets  became  harder  to  identify,  the  industry  turned  to  drug  targets  that  were 
unachievable using small molecules. More complex drug modalities such as monoclonal antibodies, therefore, 
became the predominant therapeutic class in several important disease areas and currently represent the fastest 
growing segment in the drug industry.  

More recently, various gene editing technologies such as RNAi and CRISPR have been used to modulate new 
classes of intracellular targets and will undoubtedly generate therapeutically useful drugs in the future. However, 
a major hurdle that continues to hold back the clinical development of many complex drug modalities is delivery.

Why stem cell exosomes? 
Stem cells naturally communicate with other cells by releasing exosomes, nano-sized delivery vehicles that 
carry biologically active molecules such as RNA and protein from one cell to another, thereby enhancing 
intracellular communication.  

The surface membrane of an exosome provides a protected and controlled internal microenvironment, allowing 
cargo within the exosome to travel long distances within tissues without degradation. Specific characteristics 
of the exosome (i.e. surface marker profile and lipid composition), determined by their stem cell type of origin, 
facilitate the delivery of their cargo in a targeted manner. Charts on page 10 – ELISA surface marker profile 
highlight the difference between exosomes produced from different cell types. The charts represent the surface 
marker profile of four different exosome types; three from our proprietary stem cell lines, compared to a generic 
HEK 293 cell. While the size distribution for each exosome population is similar for all exosomes, the charts 
illustrate the unique surface marker profile of the different exosome types. Even the classic markers of exosomes 
(CD9, CD63 and CD81) are expressed at different levels between the exosome types. This, coupled with the 
presence or absence of surface markers specific to the cell type of origin, facilitates interactions between the 
exosome and the target cell. Therefore, choosing the correct cell source is an important consideration when 
developing any exosome-based drug delivery vehicle.  

Interactions between the exosome and the target cell can occur through several different mechanisms, allowing 
active molecules on the surface or held within the exosome to deliver a functional effect. 

Studies have shown that entire exosomes can be internalised or can fuse directly with the cell surface to deliver 
their payload into the cytoplasm of the cell. Alternatively, proteins expressed on the surface of the exosome 
can activate specific receptors on the surface of the target cell. 

Either way, the net result of exosome-cell interactions is a functional change of the target cell, ultimately 
influencing the biology of the target tissue.  

A significant advantage of an exosome-based delivery vehicle is its superior safety profile. Exosomes have been 
shown to be non-toxic and non-immunogenic, potentially allowing for larger doses to be administrated and 
creating the possibility for re-administration, where existing delivery technologies such as lipid nanoparticles 
(LNPs) or viral vectors have failed.  

Other drug delivery systems  
Lipid nanoparticles and viral vectors such as lentivirus and adeno-associated virus (AAV) are recognised drug 
delivery  systems  for  certain  complex  drug  modalities  (see  table  1  overleaf  which  sets  out  the  relative 
capabilities of four delivery technologies with +++ being highest and + the lowest). The use of LNPs was first 
approved in 2018 for the delivery of small-interfering siRNA (Patisiran), however, they have become widely 
recognised following their use to deliver RNA-based COVID-19 vaccines in 2020. The first AAV-based therapy 
was  approved  in  2017  (Luxturna)  where  the  technology  was  used  to  deliver  a  replacement  gene  for  the 
treatment of an inherited eye disorder causing progressive blindness.

* ReNeuron predicts an advantage compared to exosomes derived from a single genetic cell line, when matching 
exosome source to target tissue. 

While both viral vectors and LNPs have demonstrated their use in certain situations, there are currently significant 
limitations to both technologies. Certain components of viral vectors share similarities to their parent viruses, which 
the mammalian immune system has evolved to recognise as an infectious agent, and this can therefore, trigger an 
immune response or activate pre-existing immunity.  

Key advantages over existing delivery technology 
l      Multiplex delivery (2 + payloads) 

l      Tissue targeting 

l      Safety profile – re-administration possible 

Payload versatility of exosomes 
Based on clinically proven technology, ReNeuron has developed a platform to exploit the natural function of stem 
cell-derived exosomes to enable the delivery of complex therapeutics to specific cells and tissues, thereby potentially 
overcoming many of the challenges facing the drug delivery and targeted therapy fields.  

Typical types of therapeutic cargos: 

l      siRNA 

l      Soluble protein 

l      Membrane-associated protein 

l      Small molecules 

l      Gene editing systems (i.e. CRISPR/Cas)  

Through either genetic modification of the stem cell line or direct loading of therapeutic modalities onto purified 
exosomes, ReNeuron has developed and patented the technology to modify the cargo of stem cell-derived exosomes 
to load a range of payloads either on the exosome surface, into the centre (lumen), or both simultaneously.

Genetic  engineering  of  our  proprietary  stem  cell  lines  allows  us  to  not  only  insert  (knock-in)  different  complex 
therapeutic molecules, such as proteins or nucleic acids, but also to permanently remove (knock-out) potentially 
unwanted components from stem cell-derived exosomes, reducing the possibility of off-target effects. This technique 
creates a stably modified stem cell line and highly consistent loaded exosomes for ease of manufacture at a scale 
relevant  for  clinical  development.  Furthermore,  the  same  approach  acts  as  a  blueprint  for  loading  a  variety  of 
therapeutic molecules, thus considerably reducing development timelines for other therapeutic candidates.  

Depending on the therapeutic modality, an alternative approach is to utilise the native stem cell-derived exosome 
and passively or actively load therapeutics into the centre or onto the surface of the exosomes. Depending upon the 
individual properties of the active molecule, loading can be achieved by simply mixing the two components or by 
utilising a concentration gradient. 

ELISA surface marker profile 
The charts overleaf clearly demonstrate that each exosome population produced from a specific cell line is unique. 
The presence or absence of different surface markers will allow the exosome to bind to specific cells to achieve 
targeted delivery of a payload.

Ability to load exosome through passive, active or genetic engineering 
Focus at ReNeuron is on specific loading of exosomes, either through passively loaded exosomes or engineered 
exosomes. For ‘passive loading’ (chemical) the exosomes are isolated first, then the cargo is loaded afterwards. In 
‘engineered’ (biological) exosomes you first start by genetically modifying the producer cell line.  

These  cells  are  instructed  to  produce  and  package  molecules  of  interest  during  exosome  generation.  These 
‘engineered’ exosomes are isolated as normal but now carry the intended additional cargo. It is also worth mentioning 
that the cargo can be placed either inside or outside the exosome, therefore, creating a vast number of possibilities 
for therapeutic agent delivery.

RENEURON’S EXOSOMES PLATFORM – What makes us different? 

OUR TECHNOLOGY 

CustomEX™, A customisable exosome delivery platform optimised for specific delivery needs 
At ReNeuron, we have developed seven proprietary, conditionally immortalised exosome producer cell lines, each 
with a distinct surface marker profile determined by their cell type of origin. We believe that this catalogue of exosome 
producing stem cell lines, from neural and non-neural tissue, differentiates us from others in the field by giving us a 
truly customisable platform and a greater chance of success when targeting specific tissues within the body.  

An essential feature of any delivery vehicle is consistency. Conditional immortalisation of stem cell exosome producer 
lines offers an elegant solution to not only produce cell lines that are genetically stable and can be grown at scale, 
but also to produce a high yielding source of consistent exosomes for the delivery of complex drug modalities.

The  standard  approach  used  by  our  competitors  is  to  produce  exosomes  from  a  single  generic  cell  line. 
A one-size-fits-all approach. A single cell line, giving rise to a single outcome. At ReNeuron, we have developed the 
CustomEX™ platform, a portfolio of stem cell exosomes that have distinct cell and tissue targeting capabilities. This 
allows us to choose the most appropriate exosome delivery vehicle, not only based upon its tissue targeting but also 
upon the specific requirements of the therapeutic payload in terms of the cellular compartment that the cargo needs 
to reach to achieve a therapeutic effect (i.e. the fluid that fills the cell (cytoplasm) for RNAi and the nucleus for DNA). 

The current portfolio of stem cell exosomes can also be rapidly expanded using ReNeuron’s proprietary CI-iPSC lines. 
Additional stem cell exosome producer lines from any cell lineage can be generated from our CI-iPSCs if the specific 
exosome population does not already form part of our catalogue. 

OUR KNOW-HOW 
The ReNeuron team has extensive know-how in the field with our Chief Scientific Officer having in excess of 15 years’ 
experience in stem cell and stem cell-based exosomes as well as extensive knowledge of the biology of the field. 

Through the years of experience gained in the manufacture of consistent stem cell banks to enable the manufacture 
of drug product, in accordance with good manufacturing practice (GMP), for use in two clinical stem cell programmes, 
the team has become expert in process and analytical development as well as manufacturing and technology transfer. 
All of which is highly valuable for the exosomes platform, which involves many of the same upstream processes for 
exosomes production.

OUR PATENTS 
ReNeuron believes it has the third largest patent estate globally in the field of exosomes, highlighting its strength 
and depth in the field. The Group has eight different patent families with patent lives in to the 2030s and beyond. 

One of our major patent families covers any neural stem cells that make exosomes. It has been granted in the EU 
and many other countries and is pending in the US. The Group already has a granted patent for the use of an exosome 
generated from any neural stem cell to treat Nestin positive cancers in the US, EU and other territories. 

The other key patent family surrounds ReNeuron’s conditional immortalisation technology and covers the use of a 
conditionally immortalised cell to produce exosomes. It encompasses a wide range of cell types including, but not 
limited to, mesenchymal stem cells (MSCs), haematopoietic stem cells, very small embryonic-like stem cells (VSELs), 
iPSCs, fibroblasts and dendritic cells. 

OUR INDUCED PLURIPOTENT STEM CELLS (iPSCs) 
Human  pluripotent  stem  cells  (hPSCs)  have  great  potential  in  cell  therapy  because  of  their  unique  ability  to 
differentiate into all cell types found in the human body. They provide, at least in theory, an inexhaustible supply of 
cells to treat any condition caused by cell loss. The archetypal hPSC is the embryonic stem cell (hESC), derived from 
the preimplantation embryo. Ethical issues surrounding the use of hESCs for medical applications have, however, 
driven the search for an alternative cell source.  

In a method first pioneered by Shinya Yamanaka in 2006, adult cells were reprogrammed to a pluripotent state 
generating induced pluripotent stem cells (iPSCs). This creates a cell source with all the benefits associated with 
pluripotency without the associated ethical issues of hESCs.  

ReNeuron’s neural stem cell line, CTX, is a clinical grade stem cell line capable of generating several types of neural 
cells. It is immortalised with a transgene whose activity is easily controllable with a synthetic drug. 

ReNeuron  have  successfully  reprogrammed  CTX  cells  to  pluripotency,  to  conditionally  immortalised  induced 
pluripotent  stem  cells  (CI-iPSCs),  and  have  demonstrated  that  CI-iPSCs  display  many  features  characteristic  of 
pluripotent cells. 

Differentiation experiments show that CI-iPSCs can create cells from all three of the early cell lineages (endoderm, 
mesoderm and ectoderm), confirming that they are truly pluripotent and hence able to create all cell types in the 
body. This includes clinically important cell types such as mesenchymal stem cells, beating heart muscle, cells of the 
immune system, including the T-cells used in modern anti-cancer cell therapy, and various types of neural cells.  

The preferred therapeutic cells for a given application are often adult stem cells or progenitors rather than the 
differentiated cells lost in disease. Such cells can be difficult to manufacture, and their short lifespan limits their 
clinical use. 

ReNeuron’s unique conditionally immortalised iPSCs has the potential to resolve many of these issues. Following 
differentiation along a particular lineage, activation of the conditional immortalisation technology within CI-iPSCs 
allow the resulting cells to be purified, qualified, expanded and banked. Thus, enabling a large number of patients 
to be treated with CI-iPSC-derived cells or cell products (e.g. exosomes) as an “off-the-shelf” medicine. Furthermore, 
as these CI-iPSC-derived therapeutics are made from a cell line which has already passed clinical phase safety trials 
(CTX), their entry into clinical trials for new indications are likely to be more rapid.

During the financial year costs continued to be closely controlled with spend primarily directed towards progressing 
the CustomEXTM proprietary exosome platform. In January 2023, the Company undertook a restructuring of the 
business with headcount reducing by 40% and the variable costs of the business lowered. 

The  full  benefit  of  these  cost  savings  will  not  be  seen  until  the  next  financial  year,  but  the  decision  made  in 
January 2022 to shift away from clinical development programmes to the exosome platform has enabled a reduction 
in costs of £4.0 million compared to the year ended 31 March 2022. As a result, the total comprehensive loss for the 
year reduced to £5.4 million (2022: £9.7 million). 

At 31 March 2023, the Group had cash, cash equivalents and bank deposits of £7.2 million with the latest base case 
forecast showing a cash runway to July 2024. This base case forecast includes assumed further revenues/funding. 
Without such revenues/funding, the forecast indicates a cash runway until February 2024. Details on the Directors’ 
assessment on going concern is provided in note 3 to the financial statements.

Revenue and other operating income 
In the year to 31 March 2023, revenues, which relate to research and collaboration activities and royalty income, were 
£530,000 (2022: £403,000). 

Operating expenses 
Total operating expenses reduced in the year to £7.6 million (2022: £11.6 million). 

As  noted  above,  this  reduction  in  costs  follows  the  strategic  decision  made  in  January  2022  to  halt  clinical 
development and instead focus resources on the exosome platform. Research and development costs in the year 
reduced to £4.5 million (2022: £8.1 million), primarily reflecting the refocussing of activities as described above, 
together with other cost reductions. General and administrative expenses also reduced in the year to £3.2 million 
(2022: £3.6 million). 

Finance income/expense 
Finance income represents income received from the Group’s cash and investments and gains from foreign exchange. 

Finance income was £478,000 in the year (2022: £195,000), the increase on the prior year being explained by an 
increase in both interest receivable and foreign exchange gains. In the year, finance expense solely comprises lease 
interest of £20,000 (2022: £25,000). 

Taxation 
Taxation for the year at £1.2 million primarily comprises an R&D tax credit (2022: £1.4 million). The amount of the 
R&D tax credit for the year has reduced as a result of the lower research and development spend in the year.

Cash flow 
Net cash used in operating activities in the year increased to £7.5 million (2022: £7.4 million). Cash used was higher 
than the loss for the year explained by changes in working capital and capital investment made to support exosome 
platform development. 

The Group had cash, cash equivalents and bank deposits totalling £7.2 million as of 31 March 2023 (31 March 2022: 
£14.5 million). 

Statement of financial position 
Non-current assets – Property, plant and equipment have increased as we invest in our exosome technology platform. 

Current assets – Corporation tax receivable of £1.2 million comprises the amount due from R&D tax credits for the 
full year ended 31 March 2023 (2022: £1.4 million). This debtor is lower than 2022 due to the reduction in research 
and development expenditure. 

Current liabilities – Trade and other payables at £4.2 million have reduced (2022: £6.9 million). This reduction primarily 
reflects changes in the level of accruals (mainly across the legacy clinical trials).

entitlement and health insurance or gym membership. 

Details of the Group’s employee share schemes are set out in note 26 to the financial statements. 

Diversity 
The Board believes in a diverse and gender balanced workforce and the Group’s Equal Opportunities Policy 
ensures the provision of equal opportunities in all areas of employment. 

At 31 March 2023 the Group employed 13 men and 13 women across a diverse range of backgrounds and had 
20% female representation on the Board with 33% women on the Senior Management Team. Details of Board 
membership are on pages 23 to 25 and the Senior Management Team on pages 26 to 27. 

Employee engagement 
Employee engagement is described in the Section 172 Report on page 17. 

Development 
Employees have significant opportunities for learning and development, often identified from the annual 
appraisal process. Examples include PhD studies, process management and quality management skills such as 
Six Sigma Black Belt, as well as soft skills courses and various formal training courses identified as part of 
employees’ annual personal development plans. 

Health and safety 
Keeping its employees safe is a priority for the Group. A Health and Safety (H&S) Committee meets regularly, 
monitors  performance  and  drives  improvements  through  H&S  Committee  representatives.  A  number  of 
employees work in a laboratory environment and are trained and required to comply with the relevant regulations 
and best practice. The H&S Committee reports to the Group’s Senior Management Team and the Board. 

The Group also offers Employee Wellbeing support. 

Policies and procedures 
The Group has a comprehensive Employee Handbook and supporting policies which set standards for ensuring 
that the Group’s business activities are conducted in a responsible manner for the benefit of its shareholders, 
employees, research partners and suppliers. The Board believes that ensuring employees understand their 
responsibilities and act in an ethical way is vital to the Group’s future success. 

Our social impacts 
The  Group  endeavours  to  maintain  links  with  universities  and  local  schools.  University  students  and 
schoolchildren have visited the Pencoed site and been given an introduction to practical research based science. 
The Group has supported PhD research, and placements are provided from time to time. 

Environmental impact 
Due to the nature of the business, the Board considers that the Group has a low environmental impact. The Group 
seeks to minimise any environmental impact of its operations and complies with relevant regulations and legislation.

are 

significant 
There 
inherent risks in developing 
stem  cell  or  stem  cell-
based exosome therapies 
for commercialisation due 
to  the  long  and  complex 
development process. 

Any therapy that we or our 
partners/licensees wish to 
offer  commercially  in  the 
future  to  the  public  must 
be put through extensive 
research,  pre-clinical  and 
clinical development, all of 
which  takes  several  years 
and  is  extremely  costly. 
The  regulatory  process  is 
both  complex  and  multi-
jurisdictional. 

Clinical potential impact 

The Group or licensed partners may fail 
to successfully develop a drug candidate 
incorporating  the  Group’s  stem  cell  or 
delivery technologies because it cannot 
be demonstrated in clinical trials that it 
is safe and efficacious. 

The  Group  and  its  partners/licensees 
may  fail  to  successfully  out-license 
products  that  have  been  developed 
and/or products may be returned from 
partners. 

Delays in achieving regulatory approval 
of any product utilising the Group’s stem 
cell or delivery technology may impose 
substantial costs on the business. 

If a product is approved, the regulators 
may impose additional requirements, for 
example,  restrictions  on  the  therapy’s 
indicated  uses  or 
levels  of 
the 
reimbursement receivable. 

Once  approved,  the  product  and  its 
manufacture  will  continue 
to  be 
reviewed by the regulators and may be 
withdrawn or restricted. 

Regulatory potential impact  

Reduction of an income stream through 
regulation  could  adversely  affect  the 
commercial viability of a drug product. 

Withdrawal  of  a  drug  product  by  a 
particular  regulatory  agency  would 
prevent sale in that particular territory 
and  may  be  followed  by  regulators  in 
other territories.

The Group looks to employ suitably 
qualified  and  experienced  staff.  It 
also consults, where necessary, with

Additionally,  the  Group  seeks  to 
foster  a  culture  where  quality  is  a 
key priority.

The  Group  will  seek  via 
its 
partners/licensees  to  take  drug 
candidates, 
the 
Group’s  stem  cell  or  delivery 
technology, to the clinic by working 
in  partnership  with  other  parties. 
This  will  increase  the  pool  of 
expertise  available  to  the  Group 
and  mitigate  further  clinical  and

Both the Group and its clinical and

Going concern 
The operations of the Group and Company are financed from funds that have been raised from share placings, 
commercial partnerships and grants.  

The goal of the Group is to achieve the commercial validation of the CustomExTM platform by generating in 
vivo data aimed at differentiating the platform from that of the Group’s competitors. In addition, the plan is to 
realise value from the Group’s other assets via potential out-licencing and/or disposal. The Directors continue 
to seek opportunities to secure further revenues/funding sufficient for the short to medium term future needs 
of the business and favourable in vivo data should enhance those opportunities. 

As previously noted, in January 2023, the Group undertook a restructuring of the business with the underlying 
cost base reduced and resources re-aligned to meet the immediate needs of the business. Based on the 
Directors base case assessment, the current cash runway is forecast to extend until July 2024, at which point a 
further capital injection would be required. The base case assessment includes assumed upfront payments over 
the next 6 to 12 months from potential future partners and collaborators on the Group’s exosome platform, 
intellectual property (IP) and legacy assets and potential further equity fund raising. The Directors recognise 
that not all of these assumed inflows are fully within the control of the Group and Company and have prepared 
a further plausible but downside scenario which excludes these inflows and indicates a cash runway until 
February 2024. 

Based on the forecasts prepared and considered by the Board, the Directors consider it appropriate to continue 
to adopt the going concern basis in the preparation of these financial statements. However, there is no guarantee 
that attempts to secure adequate cash inflows from the Group’s exosome platform, IP and legacy assets or 
through equity fund raising with the timescales stated above will be successful. These conditions indicate the 
existence of a material uncertainty, which may cast significant doubt about the Group’s and Company’s ability to 
continue as a going concern. These financial statements do not include the adjustments that would result if the 
Group and Company were unable to continue as a going concern. 

Engagement with suppliers, customers and others 
The Group and Company’s engagement with suppliers, customers and others is detailed in the Strategic Report. 

Energy and carbon reporting  
The Company and its subsidiaries are low energy users and also fall below Streamlined Energy and Carbon 
Reporting requirements, hence no energy usage information is provided. 

Statement of Directors’ responsibilities in respect of the financial statements 
The Directors are responsible for preparing the Annual Report and Accounts 2023 and the financial statements 
in accordance with applicable law and regulation. 

Company law requires the Directors to prepare financial statements for each financial year. Under that law the 
Directors have prepared the Group and the Company financial statements in accordance with UK-adopted 
international accounting standards. 

Under company law, 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 Group and Company and of the profit or loss of the Group 
for that period. In preparing the financial statements, the directors are required to: 

l       select suitable accounting policies and then apply them consistently; 

l       state whether applicable UK-adopted international accounting standards have been followed, subject to 

any material departures disclosed and explained in the financial statements; 

l       make judgements and accounting estimates that are reasonable and prudent; and 

l       prepare the financial statements on the going concern basis unless it is inappropriate to presume that the 

Group and Company will continue in business.

The Directors are responsible for safeguarding the assets of the Group and Company and hence for taking 
reasonable steps for the prevention and detection of fraud and other irregularities. 

The Directors are also responsible for keeping adequate accounting records that are sufficient to show and 
explain the Group’s and Company’s transactions and disclose with reasonable accuracy at any time the financial 
position of the Group and Company and enable them to ensure that the financial statements comply with the 
Companies Act 2006. 

The directors are responsible for the maintenance and integrity of the Company’s website. Legislation in the 
United Kingdom governing the preparation and dissemination of financial statements may differ from legislation 
in other jurisdictions. 

Directors’ confirmations 
In the case of each Director in office at the date the Directors’ Report is approved: 

l       so far as the Director is aware, there is no relevant audit information of which the Group’s and Company’s 

auditors are unaware; and 

l       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 Group’s and Company’s auditors are 
aware of that information. 

Independent auditors 
The auditors, PricewaterhouseCoopers LLP, have indicated their willingness to continue in office and a resolution 
concerning their reappointment will be proposed at the Annual General Meeting. 

Annual General Meeting 
The date and location of the Annual General Meeting of the Company will be communicated separately.

Corporate Governance

The Directors remain committed to maintaining high standards of transparency, ethics and corporate 
governance. 

The Quoted Companies Alliance Corporate Governance Code (The QCA Code) 
ReNeuron  has  adopted,  as  far  as  possible,  the  principles  of  the  Quoted  Companies  Alliance  Corporate 
Governance Code (the “QCA Code”). 

The QCA Code identifies ten principles to be followed in order for companies to deliver growth in long-term 
shareholder value, encompassing an efficient, effective and dynamic management framework accompanied by 
good communication to promote confidence and trust. 

The following sections set out the ways in which the Group applies the ten principles of the QCA Code in 
support of the Group’s medium to long-term success. The Investor Centre (Corporate Governance section) on 
the Group’s website also contains an index setting out the locations of relevant disclosures on the website 
and/or in the Group’s Annual Report pertaining to the Group’s application of the QCA Code. 

1. Establish a strategy and business model which promote long-term value for 
shareholders 
The strategy and business operations of the Group are set out in the Strategic Report on pages 2 to 22. 

The Group’s strategy and business model, and amendments thereto, are developed by the Executive Chairman, 
the Chief Financial Officer and the rest of the senior management team, and approved by the Board. The senior 
management team, is responsible for implementing the strategy and managing the business at an operational 
level. 

The Group’s overall strategic objective is to develop a best-in-class exosomes delivery platform, harnessing its 
unique stem cell technologies to develop off-the-shelf treatments for diseases with significant unmet needs, 
either alone or with partners. 

The Group deploys its financial and other resources towards gaining collaborative development opportunities 
in areas of scientific and commercial interest for its exosome and induced pluripotent stem cell (iPSC) technology 
platforms. Concurrently, it continues to seek further out-licensing opportunities for its legacy CTX and hRPC 
therapeutic products, which have already been licensed to Fosun Pharma in China. Ultimately, the Directors 
believe that this approach will deliver significant long-term value for shareholders if the data are compelling. 

The short term strategy of the Group is to realise monetary value in a platform technology or a therapeutic 
product via high-value out-licensing deals with pharmaceutical or biotechnology companies with interests in 
the relevant therapeutic field and/or geographical territories. In the medium term, if resources permit, and with 
shareholder support, the Group may choose to advance a therapeutic candidate through early-stage clinical 
development unpartnered in order to increase value in the programme prior to out-licensing to a suitable 
partner to complete further clinical development. 

The Group operates in an inherently high risk and heavily regulated sector and this is reflected in the principal 
risks and uncertainties set out on pages 19 to 22. In executing the Group’s strategy and operational plans, 
management  will  typically  confront  a  range  of  day-to-day  challenges  associated  with  these  key  risks  and 
uncertainties, and will seek to deploy the identified mitigation steps to manage these risks as they manifest 
themselves. 

2. Seek to understand and meet shareholder needs and expectations 
The Group seeks to maintain a regular dialogue with both existing and potential new shareholders in order to 
communicate the Group’s strategy and progress and to understand the needs and expectations of shareholders. 

Beyond the Annual General Meeting, the Executive Chairman, Chief Financial Officer and, where appropriate, 
other members of the senior management team meet regularly with investors and analysts to provide them 
with updates on the Group’s business and to obtain feedback regarding the market’s expectations of the Group.

The Group’s investor relations activities encompass dialogue with both institutional and private investors. The 
Company is a regular presenter at private investor events, providing an opportunity for those investors to meet 
with representatives from the Group in a more informal setting. 

3. Take into account wider stakeholder and social responsibilities and their 
implications for long-term success 
The  Group  is  aware  of  its  corporate  social  responsibilities  and  the  need  to  maintain  effective  working 
relationships across a range of stakeholder groups. These include the Group’s employees, partners, suppliers, 
regulatory authorities and the patients that have been involved in the Group’s clinical development activities. 
The Group’s operations and working methodologies take account of the need to balance the needs of all of 
these stakeholder groups, while maintaining focus on the Board’s primary responsibility to promote the success 
of the Group for the benefit of its members as a whole. The Group endeavours to take account of feedback 
received  from  stakeholders,  making  amendments  to  working  arrangements  and  operational  plans  where 
appropriate and where such amendments are consistent with the Group’s longer-term strategy. 

The Group takes due account of any impact that its activities may have on the environment and seeks to 
minimise this impact wherever possible. Through the various procedures and systems it operates, the Group 
ensures full compliance with health and safety and environmental legislation relevant to its activities. 

4. Embed effective risk management, considering both opportunities and threats, 
throughout the organisation 
The Board is responsible for the systems of risk management and internal control and for reviewing their 
effectiveness. The internal controls are appropriate to a business of this size and complexity and are designed 
to manage rather than eliminate risk and provide reasonable but not absolute assurance against material 
misstatement or loss. Through the activities of the Audit Committee, the effectiveness of these internal controls 
is reviewed annually. Key elements of the system of internal control include: 

l       setting and communicating clear strategic goals; 

l       a comprehensive budgeting process is completed once a year and is reviewed and approved by the 

Board; 

l       the Group’s results, compared with the budget, are reported on a monthly basis; 

l       the Group reforecasts the budget as necessary during the financial year, with the results reviewed and 

approved by the Board; 

l       working within a defined set of delegated authorities, approved by the Board; and 

l       all material contracts are reviewed by an Executive Director of the Company and external legal advice is 

taken as appropriate. 

The Group’s regulated activities are governed by appropriate Standard Operating Procedures. Staff behaviour 
is governed by appropriate policies including an Anti-Bribery Policy. 

The Group maintains appropriate insurance cover in respect of actions taken against the Directors because of 
their roles, as well as against material loss or claims against the Group. The insured values and type of cover 
are comprehensively reviewed on a periodic basis. 

The senior management team meet at least twice monthly to consider new risks and opportunities presented 
to the Group, making recommendations to the Board and/or Audit Committee as appropriate. 

A summary of the principal risks and uncertainties facing the Group, as well as mitigating actions, are set out 
on pages 19 to 22.

5. Maintain the Board as a well-functioning, balanced team led by the Chair 
At 31 March 2023, the Board comprised the Executive Chairman, three Non-Executive Directors, and one 
Executive Director. 

Directors’ biographies are set out on pages 23 and 25. 

All of the Directors are subject to election by shareholders at the first Annual General Meeting after their 
appointment to the Board and will continue to seek re-election at least once every three years. 

The Board is responsible to the shareholders for the proper management of the Group and meets at least six 
times a year to set the overall direction and strategy of the Group, to review scientific, operational and financial 
performance and to advise on management appointments. All key operational and investment decisions are 
subject to Board approval. A schedule of Matters Reserved for the Board may be found in the Corporate 
Governance Policies on the Group’s website. 

There were 13 formal Board meetings held in the year ended 31 March 2023. 11 of these meetings were held 
remotely. 

A summary of Board and Committee meetings attended in the year ended 31 March 2023 is set out below:

The Board considers itself to be sufficiently independent. The QCA Code suggests that a board should have 
at least two independent Non-Executive Directors. Barbara Staehelin is Senior Independent Non-Executive 
Director (SINED). She, Dr Mike Owen and Martin Walton are regarded as independent Non-Executive Directors 
under the QCA’s Code’s guidance for determining such independence. 

The Board has deemed that Iain Ross who is Executive Chairman, is not independent because his remuneration 
package includes eligibility to receive share options with a performance condition. 

Non-Executive Directors receive their fees in the form of a basic cash fee. Non-Executive Directors do not 
receive share options as part of their remuneration package. The current remuneration structure for the Board’s 
Non-Executive Directors is deemed to be proportionate and in line with general market practice. 

The Executive Chairman has received share options which are set out in the Directors’ Remuneration Report 
on page 41. 

6. Ensure that between them, the Directors have the necessary up-to-date 
experience, skills and capabilities 
The Board considers that all of the Non-Executive Directors are of sufficient competence and calibre to add 
strength and objectivity to the Board, and bring considerable experience in scientific, operational and financial 
development of biopharmaceutical products and companies. 

Directors’ biographies are set out on pages 23 to 25. The Board regularly reviews its composition to ensure 
that it has the necessary breadth and depth of skills to support the ongoing development of the Group. 

The Executive Chairman, in conjunction with the Company Secretary, ensures that the Directors’ knowledge is 
kept up to date on key issues and developments pertaining to the Group, its operational environment and to

the Directors’ responsibilities as members of the Board. During the course of the year, Directors received 
updates from various external advisers on a number of corporate governance matters. 

Directors’ service contracts or appointment letters make provision for a Director to seek personal advice in 
furtherance of their duties and responsibilities, normally via the Company Secretary. 

7. Evaluate Board performance based on clear and relevant objectives, seeking 
continuous improvement 
The Board has a process for evaluation of its own performance, that of its committees and individual Directors, 
including the Executive Chairman. This process is conducted biennially and last took place in April 2021 and is 
scheduled  to  be  completed  in  June  2023.  The  Executive  Chairman  and  SINED  are  managing  the  2023 
evaluation  process.  Evaluation  criteria  include  Controls  and  Procedures,  Strategic  Aims,  Entrepreneurial 
Leadership and Communications and Relationships and will be conducted through a series of questionnaires 
and face to face interviews. 

The Board may utilise the results of the evaluation process when considering the adequacy of the composition 
of the Board and for succession planning. 

8. Promote a corporate culture that is based on ethical values and behaviours 
The Board seeks to maintain the highest standards of integrity and probity in the conduct of the Group’s 
operations. These values are enshrined in the written policies and working practices adopted by all employees 
in the Group. An open culture is encouraged within the Group, with regular communications to staff regarding 
progress and staff feedback regularly sought. Regular meetings are held with an opportunity for anonymous 
Q&A and suggestions on any aspect of the business. The Executive Committee regularly monitors the Group’s 
cultural environment and seeks to address any concerns that may arise, escalating these to Board level as 
necessary. 

The Group is committed to providing a safe environment for its staff and all other parties for which the Group 
has a legal or moral responsibility in this area. The Group operates a Health and Safety Committee, which 
meets bi- monthly to monitor, review and make decisions concerning health and safety matters. The Group’s 
health and safety policies and procedures are enshrined in the Group’s documented quality systems, which 
encompass all aspects of the Group’s day-to-day operations. 

9. Maintain governance structures and processes that are fit for purpose and 
support good decision-making by the Board 
The Board has overall responsibility for promoting the success of the Group. The Non-Executive Directors are 
responsible for bringing independent and objective judgement to Board decisions. 

Following the departure of the CEO, the Chairman has assumed executive responsibility for the running of the 
business and has regular meetings (at least every two weeks) with the SINED to discuss key developments and 
ongoing plans. The Chairman is also responsible for overseeing the running of the Board, ensuring that no 
individual or group dominates the Board’s decision-making and ensuring the Non-Executive Directors are 
properly briefed on matters. The Chairman has overall responsibility for corporate governance matters in the 
Group. 

Senior Independent Non-Executive Director 
The principal role of the SINED is to support the Executive Chairman in their role; to act as an intermediary for 
other Non-Executive Directors when necessary; to lead the Non-Executive Directors in the oversight of the 
Executive Chairman; and to ensure there is an appropriate division of responsibility between the Executive 
Chairman and the CFO and leadership team. 

The SINED provides an alternative to the Executive Chairman or CFO for communication with shareholders, 
providing an additional conduit for issues, concerns or observations to be expressed. Additionally, the SINED

will lead the Non-Executive Directors in the annual performance evaluation of the Executive Chairman, including 
the working relationship between the Executive Chairman, the CFO and the leadership team. 

The Executive Chairman is responsible for implementing the strategy of the Board and managing the day-to-
day business activities of the Group. The Company Secretary is responsible for ensuring that Board procedures 
are followed and applicable rules and regulations are complied with. 

Board committees 
The Board has established an Audit Committee, Remuneration Committee and Nominations and Corporate 
Governance Committee with formally delegated duties and responsibilities. 

Audit Committee 
The Audit Committee comprises Barbara Staehelin (Chair), Dr Mike Owen and Martin Walton. It normally meets 
twice a year, which the Board deems to be sufficiently frequent in order for the Committee to discharge its 
responsibilities in the normal course of annual events. It has responsibility for, amongst other things, planning 
and reviewing the Annual Report and Accounts and interim statements involving, where appropriate, the 
external auditors. The Committee also approves external auditors’ fees and ensures the auditors’ independence, 
as well as focusing on compliance with legal requirements and accounting standards. It is also responsible for 
ensuring that an effective system of internal control is maintained. The ultimate responsibility for reviewing and 
approving the annual financial statements and interim statements remains with the Board. 

The Audit Committee Report is set out on pages 37 to 38. 

Remuneration Committee 
The Remuneration Committee comprises Dr Mike Owen (Chair), Barbara Staehelin and Martin Walton. It meets 
as required, but at least once a year, has responsibility for making recommendations to the Board on the 
compensation of senior executives and determining, within agreed terms of reference, the specific remuneration 
packages for each of the Executive Directors. It also supervises the Company’s share incentive schemes and 
sets performance conditions for share options granted under the schemes. 

During the year ended 31 March 2023, the Remuneration Committee met 4 times. The Committee reviewed 
and approved: 

l       the degree of achievement of objectives for the year ended 31 March 2022; 

l       the corporate and personal objectives for the Group and Executive Directors for the year ended 31 March 

2023; 

l       the exercise of share options; 

l       Executive and senior management remuneration; and 

l       the granting of share options to Directors and employees. 

Award of share options 
Following the award of share options during the year ended 31 March 2023, the total outstanding options 
exceeded 10% of the total shares in issue. Whilst the 10% figure is regarded as best practice, the Board is 
conscious of the need to incentivise and retain valued employees in order to generate value for shareholders 
and is also mindful that many of the extant options are unlikely to become exercisable in the foreseeable future. 
Having consulted with several key investors, the Board therefore approved the award of options as set out in 
note 26. 

The Directors’ Remuneration Report is set out on pages 39 to 43. The Directors believe that this, together with 
the above mentioned summary of the work of the Remuneration Committee, constitutes sufficient disclosure 
to  meet  the  QCA  Code’s  requirement  for  a  Remuneration  Committee  Report.  Consequently,  a  separate 
Remuneration Committee Report is not presented.

Nominations and Corporate Governance Committee 
The  Nominations  and  Corporate  Governance  Committee  comprises  Iain  Ross  (Chair),  Barbara  Staehelin, 
Dr  Mike  Owen  and  Martin  Walton.  It  meets  as  required  and  has  responsibility  for  reviewing  the  size  and 
composition  of  the  Board,  the  appointment  of  replacement  or  additional  Directors,  the  monitoring  of 
compliance with applicable laws, regulations and corporate governance guidance and making appropriate 
recommendations to the Board. 

During the year ended 31 March 2023, the Nominations and Corporate Governance Committee did not meet, 
primarily because matters within its remit have been discussed by the full Board. 

Corporate Governance Policies 
The terms of reference of the above Committees are set out in the Company’s Corporate Governance Policies 
document, which is regularly updated and can be found in the Investors (Corporate Governance) section on 
the Group’s website. The Corporate Governance Policies also contain a schedule of matters specifically reserved 
for Board decision or approval and sets out the Company’s share dealing code and its public interest disclosure 
(“whistle-blowing”) policy and procedures. The background to the Corporate Governance Policies is set out in 
the Corporate Governance Memorandum. 

10. Communicate how the Group is governed and is performing by maintaining a 
dialogue with shareholders and other relevant stakeholders 
The Group places a high priority on regular communications with its various stakeholder groups and aims to 
ensure that all communications concerning the Group’s activities are clear, fair and accurate. The Group’s website 
is regularly updated and users can register to be alerted when announcements or details of presentations and 
events are posted onto the website. 

Historical Annual Reports and other governance-related material can be found on the Group’s website in the 
relevant sections in the Investor Centre section of the site. 

The results of voting on all resolutions in future General Meetings will be posted to the Group’s website, 
including any actions to be taken as a result of resolutions for which votes against have been received from at 
least 20% of independent shareholders. 

By order of the Board.

Audit Committee Report 

For the year ended 31 March 2023

As Chair of the Audit Committee, I am pleased to present the Committee’s 
Report for the year ended 31 March 2023. 
The Audit Committee is a subcommittee of the Board and is responsible for ensuring effective governance 
over financial reporting and internal controls. The Committee represents the interests of the shareholders in 
relation to the integrity of information and the effectiveness of audit processes in place. 

The Audit Committee consists of three Non-Executive Directors. It is chaired by me and its other members are 
Dr Mike Owen and Martin Walton. 

I am an independent Director and have relevant financial experience. Audit Committee meetings are also 
attended, by invitation, by the Chief Financial Officer and, where appropriate, other members of the Board. 
Representatives of the external auditors also attend by invitation and meet with the Audit Committee at least 
twice a year, with time allowed for discussion without any members of the Executive team being present, to 
allow the external auditors to raise any issues of concern. 

The Audit Committee acts independently of management to ensure that the interests of shareholders are 
protected in relation to the financial reporting and internal controls. 

The principal duties of the Committee are to: 

l       monitor the integrity of the Group’s financial reporting including the review of significant financial reporting 

issues and judgements; 

l       review  and  challenge  whether  appropriate  accounting  policies  have  been  adopted,  in  particular  for 

significant or unusual transactions where different approaches are possible; 

l       review the content of the Annual Report and financial statements and advise the Board on whether, taken 
as a whole, it is fair, balanced, understandable and provides the information for shareholders to assess 
the Group’s performance, business model and strategy; 

l       keep under review the adequacy and effectiveness of the internal financial controls and internal control 

and risk management systems; 

l       review and challenge, if appropriate, any significant related party transactions; 

l       oversee the external audit process including monitoring the external auditors’ independence, objectivity, 

effectiveness and performance; 

l       review the Group’s systems and controls for detecting fraud and preventing bribery; and 

l       monitor and review the Group’s whistle-blowing arrangements. 

The Audit Committee has primary responsibility for the relationship between the Group and the external 
auditors. 

This includes: 

l       considering and recommending to the Board, to be put to shareholders for approval at the Annual General 

Meeting, in relation to the appointment, reappointment and removal of the Group’s external auditors; 

l       considering the auditors’ independence, objectivity, qualifications and effectiveness; 

l       reviewing the audit plan presented by the auditors and considering the risks identified therein; 

l       reviewing the auditors’ findings reports on the Group’s Annual Report and Financial Statements; and 

l       approving the level of fees paid to the auditors for audit and non-audit services.

Audit Committee Report 

continued

During the year ended 31 March 2023, the Audit Committee met twice. The Committee reviewed and approved 
the financial statements and the auditors’ findings report for the year ended 31 March 2022, the interim results 
for the six months to 30 September 2022 and the external auditors’ plan and fee for the 2023 external audit. 
The Audit Committee considers risk areas in the financial statements throughout the year and before the audit 
commences. It also approved an updated Whistle Blowing Policy. 

The Committee considered the following items to be areas of risk. 

The Group is expected to incur further costs as it continues to develop its technologies through the research 
and pre-clinical development pathway. The Group recognises this expenditure in line with the management’s 
best  estimation  of  the  stage  of  completion  of  each  research  and  development  project.  This  includes  the 
calculation of accrued costs at each period end to account for expenditure that has been incurred. This requires 
management to estimate full costs to complete for each project and also to estimate its current stage of 
completion. The Committee pays particular attention to management’s estimates of these items, its analysis of 
any unusual movements and their impact on cost recognition. 

The Committee reviews the going concern basis upon which the accounts are prepared. The Group is in pre-
clinical-stage development and suffers significant planned operating losses from expenses incurred in research 
and development of its platform and therapeutic programmes, as well as from general and administrative costs. 
The Group expects to continue to incur significant operating losses for the foreseeable future as it furthers its 
exosome platform and therapeutic programmes. 

The Committee has reviewed cash balances and short and long-term cashflow forecasts as well as plans to 
raise funding and considers the going concern basis to be appropriate, whilst highlighting a material uncertainty 
as further referenced in note 3 to the financial statements.  

The Audit Committee has satisfied itself that the external auditor is independent. The Audit Committee has 
concluded that the external audit process was effective, that the scope of the audit was appropriate and that 
significant judgements have been robustly challenged.  

A resolution for the reappointment of PricewaterhouseCoopers LLP as the statutory auditor will be proposed 
at the forthcoming Annual General Meeting. 

No formal recommendations other than the approval of the Interim Results and Annual Report and Financial 
Statements  have  been  made  to  the  Board  by  the  Audit  Committee  and  no  external  reports  have  been 
commissioned on financial control processes during the year ended 31 March 2023. 

By order of the Board.

Directors’ Remuneration Report 

For the year ended 31 March 2023

This report sets out the remuneration policy operated by the Company in respect of the Executive and 
Non-Executive Directors, as of the date of this report. No Director is involved in discussions relating to 
their own remuneration. 

Remuneration policy for Executive Directors 
The Remuneration Committee sets the remuneration policy that aims to align Executive Director remuneration 
with shareholders’ interests and to attract and retain the best talent for the benefit of the Group. The Committee 
has sought independent advice when setting the remuneration policy. Executive Directors are appointed under 
service contracts with notice periods not exceeding 6 months. The basic contractual working week is 37.5 hours, 
but contracts stipulate that Executive Directors are required to work whatever hours are necessary in order for 
them to fulfil their Executive responsibilities. 

Remuneration for Executive Directors is composed of the following elements: 

Basic salary 
Basic salaries are reviewed annually and revised salaries take effect from the start of the financial year. The 
review process is managed by the Remuneration Committee with reference to market salary data and the 
Executive’s performance during the year. 

Bonuses 
Annual  bonuses  are  based  on  achievement  of  Group  strategic  and  operational  objectives,  and  personal 
performance objectives. The maximum annual bonus that may be payable in cash is set at 50% of base salary 
for the Executive Directors. This may be paid in cash or share options under the Company’s Long-Term Incentive 
Plan. 

Longer-term incentives 
In order to further incentivise Executive Directors and align their interests with shareholders, the Company 
operates a Long-Term Incentive Plan under which share options may be granted from time to time. The quantum 
of these awards is approved by the Remuneration Committee and are considered in line with market levels 
and consistent with positions held. 

Executive Directors are expected to build a direct stake in the Company’s shares over time, either through the 
purchase of shares in the market from time to time and/or through the future exercise of share options. 

The Company has the ability to grant share options under its active share option schemes which in accordance 
with best practice are ordinarily granted subject to a cap of up to 10% of total issued share capital in any ten-
year period. The rules of the share options scheme give the Board the flexibility to exceed this 10% limit. During 
the year, in accordance with the rules of the share option schemes, the Board approved the grant of share 
options to the Executive Chairman, Executive Director, senior management and staff which led to the 10% cap 
being exceeded. The Board took the decision following consultation with several key shareholders being 
conscious of the need to incentivise and retain valued employees in order to generate value for shareholders 
whilst also being mindful of the fact that many of the extant options were unlikely to become exercisable in the 
foreseeable future. 

Pension 
The Group operates a defined contribution pension scheme, which is available to all employees. The Company 
contribution in respect of Executive Directors (excluding the Executive Chairman) is currently set at 10% of base 
salary. An Executive Director may choose to take some or all of this benefit as a cash alternative, subject to the 
Company remaining cash neutral after relevant payroll taxes.

Other benefits 
Other benefits provided are life assurance, private medical insurance and professional subscriptions, where 
relevant  to  the  duties  of  the  Executive  Director  (disclosed  as  part  of  Salaries  and  fees  in  the  following 
remuneration table). 

Non-Executive Directors’ remuneration 
The  remuneration  of  the  Non-Executive  Directors  is  set  at  a  level  that  is  sufficient  to  attract  and  retain 
high-calibre non-executives who contribute to the business. Fee levels are determined by the Remuneration 
Committee  with  regard  to  market  comparatives,  Board  Committee  responsibilities  and  ongoing  time 
commitments. Non-Executive Directors are appointed for an initial three-year term via an appointment letter 
from the Company, with a three months’ notice period, with the exception of the Executive Chairman who has 
a six months’ notice period. The appointment term is renewable for further three-year terms after the initial 
term has expired. Appointment letters stipulate that the Non-Executive Director is expected to commit sufficient 
time to the role to meet the Company’s expectations. 

Non-Executive Directors receive their fees in the form of a basic cash fee. The Executive Chairman receives 
share options as part of his remuneration package. Details are set out below. 

Non-Executive  Directors  do  not  receive  any  pension,  bonus  or  other  benefits  from  the  Company.  The 
remuneration of the Non-Executive Directors is reviewed by the Board annually.

give a true and fair view of the state of the group’s and of the company’s affairs as at 31 March 2023 and 
of the group’s loss and the group’s and company’s cash flows for the year then ended; 
have  been  properly  prepared  in  accordance  with  UK-adopted  international  accounting  standards  as 
applied in accordance with the provisions of the Companies Act 2006; and 
have been prepared in accordance with the requirements of the Companies Act 2006. 

We have audited the financial statements, included within the Annual Report, which comprise: the Group and 
Company Statements of Financial Position as at 31 March 2023; the Group Statement of Comprehensive 
Income, the Group and Company Statements of Changes in Equity, the Group and Company Statements 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 group in accordance with the ethical requirements that are relevant to our 
audit of the financial statements in the UK, which includes the FRC’s Ethical Standard, as applicable to listed 
entities, 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 3 to the financial statements concerning the group’s and the company’s ability 
to continue as a going concern. Based on the current financial forecasts, the directors expect that upfront 
payments from future partners and collaborators on their IP and legacy assets will enable a cash runway to July 
2024, at which point further capital injection would be required. If those upfront payments, which are not wholly 
within the control of the Group and Company, are not received then the cash runway would extend until 
February 2024. These conditions, along with the other matters explained in note 3 to the financial statements, 
indicate the existence of a material uncertainty which may cast significant doubt about the group’s and the 
company’s ability to continue as a going concern. The financial statements do not include the adjustments that 
would result if the group and the company 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.

Independent Auditor’s Report 

continued

Our evaluation of the directors’ assessment of the group’s and the company’s ability to continue to adopt the 
going concern basis of accounting included: 

•

•

•

•
•

we evaluated the directors’ model supporting their going concern assessment and considered whether 
the assumptions made supported their conclusion; 
we tested the mathematical accuracy of the model and considered the reasonableness of the assumptions 
made and the availability of cash throughout the going concern period; 
we compared underlying base assumptions against comparable costs incurred in the year to 31 March 
2023; 
we verified certain assumptions to supporting documentation; and 
we considered whether the key matters in relation to going concern are appropriately disclosed within 
the financial statements. 

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 

Overview 
Audit scope 

• We have performed full-scope audit procedures in respect of the Company, ReNeuron Group plc and it’s 

•

•

subsidiary ReNeuron Limited 
Our audit scope included limited desktop audit procedures on the subsidiary, ReNeuron Inc., which were 
performed by the Group engagement team 
Our audit procedures, all of which have been performed by the Group engagement team and which 
included  the  Group  finance  consolidation  and  financial  statement  disclosures,  covered  100%  of  the 
Group’s loss before tax for the year ended 31 March 2023. Our audit scope provided sufficient appropriate 
audit evidence as a basis for our opinion on the Group financial statements as a whole. 

Key audit matters

•
•

Material uncertainty related to going concern (group and company) 
Completeness of research and development accruals (group) 
Valuation of the Company’s investment in ReNeuron Limited (company) 

Materiality 

•
•

•

Overall group materiality: £332,900 (2022: £552,000) based on 5% of loss before tax. 
Overall company materiality: £282,000 (2022: £300,000) based on 5% of loss before tax, restricted to 85% 
of group materiality. 
Performance materiality: £249,600 (2022: £414,675) (group) and £211,500 (2022: £225,000) (company). 

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.

The key audit matters below are consistent with last year. 

Key audit matter                                                                    How our audit addressed the key audit matter 

Completeness of research and development accruals (group) 

Due to the nature of the clinical trials and general research, 
it is often difficult to estimate the amount of time a particular 
trial is going to take. The Group outsources most of its 
research and development to third parties which restricts 
visibility and the ability to monitor the progression of a piece 
of research, or a trial’s stage of completion. As a result, it 
can be difficult for the Group to measure which costs have 
been incurred in relation to a trial at a particular point in 
time and as such, based on billings received, whether 
project accruals are reasonably estimated. 

Our audit risk is focussed on whether the relevant accruals 
have been appropriately calculated and reflected on the 
balance sheet including assessing whether any releases have 
appropriate justification. As at 31 March 2023, the Accruals 
and deferred income balance for the group amounted to 
£3.8m. 

Valuation of the Company’s investment in ReNeuron Limited 
(company) 

The Group’s market capitalisation as at 31 March 2023 was 
£5.2m compared to investments in its subsidiary, ReNeuron 
Limited, of £23.3m pre any impairment. Accordingly, 
management has identified that an impairment indicator 
exists and an impairment assessment has been undertaken. 
The impairment assessment compares the carrying value to 
the recoverable amount, which is calculated as the higher of 
the value in use and the fair value less costs to sell. 

Management has performed a value in use calculation, 
based on its forecasts for the next five years. In the absence 
of other information, management has used the market 
capitalisation of the Company at 31 March 2023 as a proxy 
for the fair value less costs to sell. The recoverable amount, 
based on using the higher of these two models, is £nil, after 
taking into account the other assets that are held by the 
Company and which are considered as part of the Group’s 
market capitalisation. Accordingly an impairment of £23.3m 
has been recorded. There is complexity and judgement 
involved in calculating the valuation of the investments. 

The key judgement in regard to this balance is using market 
capitalisation as a proxy for fair value less costs to sell. The 
key estimate in regards to the value in use calculation is the 
revenue growth and R&D expenditure over the next 5 years.

We performed the following procedures: 
• We verified the status of projects through a 
meeting with the Chief Operations Officer where 
the progress and status of each project was 
discussed. 
• We obtained management’s calculations that 
support the research and development costs 
incurred during the year and verified the 
mathematical formulae used. 
• We sampled management’s calculations back to 
invoices and contracts 
• We obtained management’s calculation of the 
accrual and verified the mathematical formulae. 
• We reviewed invoices received and payments 
post 31 March 2023 and performed analytical 
procedures to identify any costs not included in 
management’s schedules 

We concluded that management’s recording of 
the accruals balance as at 31 March 2023 was 
appropriate. 

We have performed the following procedures: 
• Assessed whether market capitalisation is 
appropriate, recalculated the exercise and 
concluded that the exclusion of costs to sell and 
control premium in the fair value less costs to sell 
calculation was reasonable. 
• Considered any post year-end movements in 
share price and concluded that none were 
indicative of conditions existing before year end 
and should not therefore be reflected in the year-
end fair value less costs to sell calculation. 
• We have confirmed the mathematical accuracy 
of the value in use model, confirmed the growth 
forecasts are in line with the Board-approved plan 
and that the growth assumptions are in line with 
IAS 36. 

We have concluded that management’s 
assessment that an impairment of £23.3m is 
required in relation to the carrying value of the 
investment is appropriate.

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 and the company, the 
accounting processes and controls, and the industry in which they operate.

ReNeuron Group plc’s shares are admitted to trading on the Alternative Investment Market (“AIM”) of the 
London  Stock  Exchange  and  its  principal  activities  are  research  and  clinical  development  of  cell-based 
therapeutics. The Group’s accounting function is structured around a local finance function based in the United 
Kingdom. There are three active entities in the Group; ReNeuron Group plc (which raises the equity to support 
the  principal  activity  of  the  Group),  ReNeuron  Limited  (which  records  the  majority  of  Group  activity)  and 
ReNeuron, Inc. (which incurs certain operating costs and recharges these back to ReNeuron Limited). For each 
active entity we determined whether we required an audit of their complete financial information (“full scope”) 
or whether specified procedures addressing specific risk characteristics of particular financial statement line 
items would be sufficient. It was assessed that ReNeuron Group plc and ReNeuron Limited required full scope 
audit procedures whilst ReNeuron, Inc. did not as it contributed less than 1% of the loss before tax and 1% of 
Group total assets and contain no financial statement items that comprise more than 15% of the Group total. 

The impact of climate risk on our audit 
As part of our audit we made enquiries of management to understand the extent of the potential impact of 
climate risk on the group’s and company’s financial statements, and we remained alert when performing our 
audit procedures for any indicators of the impact of climate risk. Our procedures did not identify any material 
impact as a result of climate risk on the group’s and company’s 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: 

                             Financial statements - group            Financial statements - company

Based on the benchmarks used in the Annual Report, 
loss before tax is the most relevant measure in 
assessing the performance of the group and company 
and is a generally accepted auditing benchmark. In the 
prior year total assets was the most appropriate 
measure for the company since the principal activity of 
the company was to hold the investment in subsidiary. 
However in the current year, this investment has been 
fully impaired and the primary activity is now expense 
based. Materiality has been restricted in line with 
Group scoping in 2023 and 2022.

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 £282,000 and £316,000. Certain 
components  were  audited  to  a  local  statutory  audit  materiality  that  was  also  less  than  our  overall  group 
materiality.

Independent Auditor’s Report

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% (2022: 75%) of overall materiality, amounting to £249,600 (2022: £414,675) for the group financial 
statements and £211,500 (2022: £225,000) for the company 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 at the 
upper end 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 £16,645 (group audit) (2022: £27,600) and £14,100 (company audit) (2022: £15,000) as well as 
misstatements below those amounts 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, except to the extent otherwise explicitly stated in this report, 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. 

With respect to the Strategic report and Directors’ Report, we also considered whether the disclosures required 
by the UK Companies Act 2006 have been included. 

Based on our work undertaken in the course of the audit, the Companies Act 2006 requires us also to report 
certain opinions and matters as described below. 

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 March 2023 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 company and their 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 Directors’ responsibilities in respect of the financial statements, 
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 and the company’s 
ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using 
the going concern basis of accounting unless the directors either intend to liquidate the group or the company 
or to cease operations, or have no realistic alternative but to do so.

Independent Auditor’s Report 

continued

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  product  safety  (including  but  not  limited  to  drug  regulation)  and 
employment legislation (including health & safety regulation), 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 tax legislation and the Companies Act 
2006. 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 
inappropriate journal entries and management bias in accounting entries. Audit procedures performed by the 
engagement team included: 

•

•
•
•

Discussions  with  management,  including  consideration  of  known  or  suspected  instances  of  non-
compliance with laws and regulations and fraud; 
Reviewing Board minutes and legal expenses; 
Identifying and testing journal entries, in particular those having unusual account combinations; and 
Designing audit procedures to incorporate unpredictability around the nature, extent and timing of our 
testing. 

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 Chapter 3 of Part 16 of the Companies Act 2006 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.

2. Accounting policies and basis of preparation  
The principal accounting policies adopted in the preparation of these financial statements are set out below. 
These policies have been consistently applied to all of the financial years presented for both the Group and 
the Company. The accounting policies relate to the Group unless otherwise stated. 

Basis of preparation 
The  financial  statements  have  been  prepared  in  accordance  with  UK  adopted  International  Accounting 
Standards (IFRS) and with the requirements of the Companies Act 2006 as applicable to companies reporting 
under those standards. 

These financial statements have been prepared on a historical cost basis unless otherwise specified. 

As permitted by Section 408 of the Companies Act 2006, the Parent Company’s statement of comprehensive 
income has not been presented in these financial statements. 

Basis of consolidation 
The consolidated financial statements include the financial statements of the Company and its subsidiary 
undertakings made up to 31 March 2023. 

The purchase method of accounting is used to account for the acquisition of subsidiaries by the Group. The 
cost of an acquisition is measured as the fair value of the assets given, equity instruments issued and liabilities 
incurred or assumed at the date of exchange, plus costs directly attributable to the acquisition. Identifiable 
assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially 
at their fair values at the acquisition date, irrespective of the extent of any minority interest. The excess of the 
cost of acquisition over the fair value of the Group’s share of the identifiable net assets acquired is recorded as 
goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the 
difference is recognised directly in the Group statement of comprehensive income. 

Intercompany transactions and balances and unrealised gains on transactions between Group companies are 
eliminated. 

Unrealised  losses  are  also  eliminated,  but  considered  an  impairment  indicator  of  the  asset  transferred. 
Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies 
adopted by the Group. 

The Group elected not to apply IFRS 3 Business Combinations retrospectively to business combinations which 
took place prior to 1 April 2006 that have been accounted for by the merger accounting method. 

Significant accounting judgements, estimates and assumptions 
The preparation of financial statements in conformity with IFRS requires the use of accounting estimates and 
assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements 
and the reported amounts of income and expenses during the reporting period. Although these estimates are 
based on management’s best knowledge of current events and actions, actual results ultimately may differ from 
those estimates. IFRS also requires management to exercise its judgement in the process of applying the 
Group’s accounting policies. 

The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates 
are significant to the consolidated financial statements are as follows:

Recognition of research and development expenditure 
The  Group  incurs  research  and  development  expenditure  from  third  parties.  The  Group  recognises  this 
expenditure in line with the management’s best estimation of the stage of completion of each research and 
development  project.  This  includes  the  calculation  of  accrued  costs  at  each  period  end  to  account  for 
expenditure that has been incurred. This requires management to estimate full costs to complete for each 
project and also to estimate its current stage of completion. Costs relating to clinical research organisation 
expenses in the year were £0.1 million, none of which met the criteria for capitalisation. The related accruals 
were £1.1 million. 

Estimated future recoverability of investment in subsidiary companies 
The Company holds an investment balance with its subsidiary companies. This is reviewed for impairment 
annually or more frequently if events or changes in circumstances indicate a potential impairment.  

The directors have considered the Group’s market capitalisation at 31 March 2023 and the carrying value of 
other assets held by the Parent Company when making an assessment of the fair value less costs to sell of its 
investment in subsidiaries. Consequently, this has been written down to £nil, giving rise to an impairment charge 
of £23.3 million (2022: £62.9 million). 

Foreign currency translation 
The consolidated financial statements are presented in pounds sterling (£), which is the Company’s functional 
and presentational currency. Foreign currency transactions are translated into the functional currency using the 
exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from 
the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and 
liabilities denominated in foreign currencies are recognised in the Group statement of comprehensive income 
in the year in which they occur. 

Revenue 
Revenue is accounted for in line with the principles of IFRS 15 Revenue from Contracts with Customers. It is 
measured at the fair value of the consideration received or receivable, net of discounts and sales-related taxes. 

Licensing agreements may contain a number of elements and provide for varying consideration terms, such as 
initial  fees,  sales,  development  and  regulatory  milestones  together  with  sales-based  royalties  and  similar 
payments. Such arrangements are within the scope of IFRS 15 and are assessed under its five-step model to 
determine revenue recognition. The distinct performance obligations within the contract and the arrangement 
transaction price are identified. The fair value of the arrangement transaction price is allocated to the different 
performance obligations based upon the relative stand-alone selling price of those obligations together with 
the performance obligation activities to which the terms of the payments specifically relate. The allocated 
transaction price is recognised over the respective performance period of each performance obligation. 

Initial fees relating to the immediate transfer of intellectual property are non-refundable and are recognised as 
revenue upon signature of the contract. 

Development and regulatory approval milestone payments are recognised as revenue when the respective 
milestones are achieved. 

Sales-based royalty income and related milestone payments are recognised in the period when the related 
sales occur or when the relevant milestone is achieved. 

Agreements that are related to development activities or technology transfer can contain a number of elements 
and provide for varying consideration terms such as payment for utilisation of staff resources and for the 
purchase of cell line related products. Such arrangements are within the scope of IFRS 15 and are assessed 
under its five-step model to determine revenue recognition. The distinct performance obligations (that can 
include agreed assigned staff resources) within the contract and the arrangement transaction price are identified. 
The fair value of the arrangement transaction price is allocated to the different performance obligation based 
on the stand-alone selling price of that obligation together with the performance obligation activity to which 
the terms of payment specifically relate. The allocated transaction price relating to the utilisation of staff is 
recognised over time and that relating from the sale of cell lines is at a point in time. 

Where the Group acts as principal in a transaction, it recognises the gross revenue to which it is entitled. If the 
Group acts as agent in a transaction, it recognises the fee or commission received.

Research and development expenditure 
Capitalisation of expenditure on product development commences from the point at which technical feasibility 
and commercial viability of the product can be demonstrated and the Group is satisfied that it is probable that 
future economic benefits will result from the product once completed. No such costs have been capitalised to 
date, given the early stage of the Group’s intellectual property.

Expenditure on research and development activities that do not meet the above criteria, including ongoing 
costs associated with acquired intellectual property rights and intellectual property rights generated internally 
by the Group, is charged to the Group statement of comprehensive income as incurred. 

Pension benefits 
The Group operates a defined contribution pension scheme. Contributions payable for the year are charged 
to the Group statement of comprehensive income. Differences between contributions payable in the year and 
contributions actually paid are shown as either accruals or prepayments in the Group and Parent Company 
statements of financial position. The Group has no further payment obligations once the contributions have 
been paid. 

Leases 
IFRS 16 Leases applies a single recognition and measurement approach for all applicable leases under which 
the Group is the lessee. 

A lease is defined as “a contract, or part of a contract, that conveys the right to use an asset (the underlying 
asset) for a period of time in exchange for consideration”. To apply this definition, the Group assesses whether 
the contract meets two key evaluations, which are whether: 

l

l

the contract contains an identifiable asset; and 

the Group has the right to obtain substantially all of the economic benefits from use of the identified asset 
throughout the period of use. 

At lease commencement date, the Group recognises a right-of-use asset and a lease liability on the balance 
sheet. The right-of-use asset is measured at cost. The Group depreciates the right-of-use assets on a straight-
line basis from the lease commencement date to the earlier of the end of the useful life of the right-of-use asset 
or the end of the lease term. The Group also assesses the right-of-use asset for impairment when such indicators 
exist. 

At the commencement date, the Group measures the lease liability at the present value of the lease payments 
unpaid at that date, discounted using the Group’s incremental borrowing rate. Lease payments included in the 
measurement of the lease liability are made up of fixed payments (including in substance fixed), variable 
payments based on an index or rate, amounts expected to be payable under a residual value guarantee and 
payments arising from options reasonably certain to be exercised. Subsequent to initial measurement, the 
liability will be reduced for payments made and increased for interest. 

Payments associated with short-term leases and all leases of low-value assets are recognised on a straight-line 
basis as an expense in profit or loss. Short-term leases are leases with a lease term of 12 months or less without 
a purchase option. Low-value assets comprise IT equipment. 

Government and other grants 
Revenue grants are credited to other income within the Group statement of comprehensive income, assessed 
by the level of expenditure incurred on the specific grant project, when it is reasonably certain that amounts 
will not need to be repaid.

Share-based payments 
The Group operates a number of equity-settled share-based compensation plans. The fair value of share-based 
payments under such schemes is expensed on a straight-line basis over the vesting period, based on the 
Group’s  estimate  of  shares  that  will  eventually  vest  and  adjusted  for  the  effect  of  market-based  vesting 
conditions. Vesting periods are estimated to be two years for options issued under the deferred bonus and 
four years for other schemes. 

The fair value calculation of share-based payments requires several assumptions and estimates as disclosed in 
note 26. The calculation uses the Black-Scholes model. At each balance sheet date, the Group reviews its 
estimate of the number of options that are expected to vest and recognises any revision to original estimates 
in the Group statement of comprehensive income, with a corresponding adjustment to equity. 

For equity-settled share-based payments, where employees of subsidiary undertakings are rewarded with shares 
issued by the Parent Company, a capital contribution is recorded in the subsidiary, with a corresponding increase 
in the investment in the Parent Company. 

Warrants 
Where warrants have been issued together with Ordinary shares, the proportion of the proceeds received that 
relates to the warrants is credited to reserves. 

Where warrants have been issued as recompense for services supplied, the fair value of warrants is charged to 
the Group statement of comprehensive income over the period the services are received and a corresponding 
credit is made to reserves. 

Intangible assets 
Intangible assets relating to licence fees have infinite lives and are not amortised but are tested for impairment 
annually. Intangible assets relating to intellectual property rights acquired through licensing or assigning patents 
and know-how are carried at historical cost less accumulated amortisation and any provision for impairment. 
Milestone payments associated with these rights are capitalised when incurred. Where a finite useful life of the 
acquired intangible asset cannot be determined, the asset is not subject to amortisation but is tested for 
impairment annually or more frequently, whenever events or changes in circumstances indicate that the carrying 
amount may not be recoverable. No amortisation other than historical impairment has been charged to date 
as the products underpinned by the intellectual property rights are not yet available for commercial use. 

Property, plant and equipment 
Property, plant and equipment are stated at cost, net of depreciation and any provision for impairment. Cost 
includes the original purchase price of the asset and the costs attributable to bringing the asset to its working 
condition for its intended use. Depreciation is calculated so as to write off the cost less their estimated residual 
values on a straight-line basis over the expected useful economic lives of the assets concerned. The principal 
annual periods used for this purpose are: 

Plant and equipment

Computer equipment

3–8 years  

3–5 years 

The residual values and estimated useful lives are reviewed annually. 

Profits or losses on disposal of property, plant and equipment reflect the difference between net selling price 
and carrying amount at the date of disposal and are recognised in the consolidated income statement. 

Investments in subsidiaries 
Investments in subsidiaries are shown at cost less any provision for impairment. Any monies paid to subsidiaries 
are deemed to be a capital contribution. 

Current income tax 
The credit for current income tax is based on the results for the year, adjusted for items that are non-assessable 
or disallowed. It is calculated using tax rates that have been enacted or substantively enacted at the financial 
year-end.

Deferred tax 
Deferred tax is provided in full, using the liability method, on temporary differences arising between the tax 
bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, 
deferred tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other 
than a business combination that at the time of the transaction affects neither accounting nor taxable profit or 
loss. Deferred tax is determined using tax rates and laws that have been enacted or substantively enacted by 
the balance sheet date and are expected to apply when the related deferred tax asset is realised or the deferred 
tax liability is settled. 

Deferred tax assets are recognised to the extent that it is probable that future taxable profit will be available, 
against which the temporary differences can be utilised. 

Trade and other receivables 
Trade and other receivables are recognised initially at fair value and subsequently measured at amortised cost 
using the effective interest method, less loss allowance. The Group assesses, on a forward-looking basis, the 
expected credit losses associated with its trade and other receivables carried at amortised cost. The impairment 
methodology applied depends on whether there has been a significant increase in credit risk. 

Bank deposits, cash and cash equivalents 
Cash and cash equivalents in the Group and Parent Company statements of cash flows and the Group and 
Parent Company statements of financial position include cash in hand and deposits with banks with original 
maturities of three months or less. Bank deposits with original maturities in excess of three months are classed 
as investments and measured at amortised cost using the effective interest rate method. Bank deposits with 
maturities between four and 12 months are disclosed within current assets and those with maturities greater 
than 12 months are disclosed within non-current assets. 

The prior year statement of cash flows has been restated due to a reclassification from financing activities to 
investing activities of a £2.5m cash inflow relating to the maturity of short term investments. This restatement 
does not impact the opening or closing cash balances. 

Trade and other payables 
These amounts represent liabilities for goods and services provided to the Group prior to the end of the financial 
year, which are unpaid. The amounts are unsecured and are, when correctly submitted, usually paid within 30 
days of recognition. Trade and other payables are presented as current liabilities unless payment is not due 
within 12 months after the reporting period. They are recognised initially at their fair value and subsequently 
measured at amortised cost using the effective interest method. 

Capital redemption reserve 
Section 733 of the Companies Act 2006 provides that where shares of a company are redeemed or purchased 
wholly out of the Company’s profits, or by a fresh issue, the amount by which the Company’s issued share 
capital is diminished on cancellation of the shares shall be transferred to a reserve called the “capital redemption 
reserve”. It also provides that the reduction of the Company’s share capital shall be treated as if the capital 
redemption reserve were paid-up capital of the Company. 

Provisions 
Provisions are recognised when the Group has a contractual or constructive obligation as a result of past events, 
for which it is probable that an outflow of resources will be required to settle the obligation and the amount 
can be reliably estimated. 

Contractual milestone payments 
The Group is expected to incur future contractual milestone payments linked to the future development of its 
therapeutic programmes. These costs will be recognised as and when a contractual milestone is expected to 
be achieved.

3. Going concern 
The operations of the Group and Company are financed from funds that have been raised from share placings, 
commercial partnerships and grants.  

The goal of the Group is to achieve the commercial validation of the CustomExTM platform by generating in 
vivo data aimed at differentiating the platform from that of the Group’s competitors. In addition, the plan is to 
realise value from the Group’s other assets via potential out-licencing and/or disposal. The Directors continue 
to seek opportunities to secure further revenues/funding sufficient for the short to medium term future needs 
of the business and favourable in vivo data should enhance those opportunities. 

As previously noted, in January 2023, the Group undertook a restructuring of the business with the underlying 
cost base reduced and resources re-aligned to meet the immediate needs of the business. Based on the 
Directors’ base case assessment, the current cash runway is forecast to extend until July 2024, at which point 
a further capital injection would be required. The base case assessment includes assumed upfront payments 
over the next 6 to 12 months from potential future partners and collaborators on the Group’s exosome platform, 
IP and legacy assets and potential further equity fund raising. The Directors recognise that not all of these 
assumed inflows are fully within the control of the Group and Company and have prepared a further severe but 
plausible downside scenario which excludes these inflows and indicates a cash runway until February 2024. 

Based on the forecasts prepared and considered by the Board, the Directors consider it appropriate to continue 
to  adopt  the  going  concern  basis  in  the  preparation  of  these  financial  statements.  However,  there  is  no 
guarantee that attempts to secure adequate cash inflows from the Group’s exosome platform, IP and legacy 
assets or through equity fund raising with the timescales stated above will be successful. These conditions 
indicate  the  existence  of  a  material  uncertainty,  which  may  cast  significant  doubt  about  the  Group’s  and 
Company’s ability to continue as a going concern. These financial statements do not include the adjustments 
that would result if the Group and Company were unable to continue as a going concern.

4. Segment analysis 
The Group has identified the Executive Chairman, as the Chief Operating Decision Maker (CODM). The CODM 
manages the business as one segment, the development of cell-based therapies, and activities and assets are 
predominantly based in the UK. Since this is the only reporting segment, no further information is included. 
The information used internally by the CODM is the same as that disclosed in the financial statements.

12. Loss for the financial year 
As permitted by Section 408 of the Companies Act 2006, the Parent Company’s statement of comprehensive 
income for the current year has not been presented in these financial statements. The Parent Company’s loss 
and total comprehensive loss for the financial year was £24,539,000 (2022: £64,520,000). The loss in the current 
year was primarily derived from the impairment of investment in subsidiaries.

13. Basic and diluted loss per ordinary share 
The basic and diluted loss per share is calculated by dividing the loss for the financial year of £5,408,000 (2022: 
£9,689,000) by 57,125,960 shares (2022: 56,975,677 shares), being the weighted average number of one pence 
ordinary shares in issue during the year. 

65

Potential dilutive ordinary shares relating to share options are anti-dilutive as they would have decreased the 
loss per share and are excluded from the calculation of diluted loss per share. Therefore, the weighted average 
shares outstanding used to calculate both the basic and diluted loss per share are the same. 

The weighted average number of diluted one pence ordinary shares (including potential dilutive ordinary shares 
related to share options) is 58,607,176 shares (2022: 58,751,314 shares).

The Company has invested in ReNeuron Limited to allow it to carry on the trade of the Group. A capital 
contribution arises where share-based payments are provided to employees of subsidiary undertakings settled 
with equity to be issued by the Company. 

The main element of the Group’s funds are raised by ReNeuron Group plc, with funds then being passed to 
subsidiary  companies  via  intercompany  transactions.  The  resultant  intercompany  debtor  is  reclassified  to 
investment in subsidiaries as a capital contribution. At 31 March 2023 the Group’s market capitalisation was 
£5.2 million as determined by the closing share price, which, when taking into account other assets held by 
the Parent Company, resulted in a further impairment of £23,335,000. The directors consider this to be a 
reasonable representation of fair value less costs to sell. The Company’s investments comprise interests in 
Group undertakings, details of which are shown below:

23. Financial risk management 

Capital management 
The Group’s key objective in managing its capital is to safeguard its ability to continue as a going concern. 
In  particular,  it  has  sought  and  obtained  equity  funding  alongside  non-dilutive  grant  support  commercial 
partnerships and collaborations to pursue its programmes. The Group strives to optimise the balance of cash 
spend between research and development and general and administrative expenses and, in so doing, maximise 
progress for all pipeline products. 

Risk 
The financial risks faced by the Group include liquidity and credit risk, interest rate risk and foreign currency risk. 

Liquidity and credit risk 
The Group seeks to maximise the returns from funds held on deposit balanced with the need to safeguard the 
assets of the business. 

The agreed policy is to invest surplus cash in interest-bearing current/liquidity accounts and term deposits and 
to spread the credit risk across a number of counterparties, the selection criteria being as follows: 

l

UK-based banks; 

l minimum credit rating with Fitch and/or Moody’s (long-term A-/A3; short-term F1/P-1); and 

l

familiar and respected names. 

At  31  March  2023  and  31  March  2022,  no  current  asset  receivables  were  aged  over  three  months. 
No receivables were impaired or discounted.

Interest rate risk 
A portion of the Group’s cash resources are placed on fixed deposit, with an original term of between three 
and 12 months, to secure fixed and higher interest rates. The Directors do not currently consider it necessary 
to use derivative financial instruments to hedge the Group’s exposure to fluctuations in interest rates.

Foreign currency risk 
The  Group  holds  part  of  its  cash  resources  in  US  dollars  and  euros  to  cover  payments  committed  in  the 
immediate future. At 31 March 2023, cash of £1,114,000 (2022: £4,213,000) was held in these currencies. 
Creditors of the Group include £1,400,000 (2022: £429,000) denominated in US dollars and £66,000 (2022: 
£149,000) denominated in euros. Of the Group’s debtors, £nil (2022: £6,000) is denominated in euros. The 
remainder are denominated in pounds sterling. 

At 31 March 2023, if pounds sterling had weakened/strengthened by 5% against the US dollar with all other 
variables held constant, the recalculated post-tax loss for the year would have been £31,000 (2022: £156,000) 
higher/lower. 

At 31 March 2023, if pounds sterling had weakened/strengthened by 5% against the euro with all other variables 
held constant, the recalculated post-tax loss for the year would have been £14,000 (2022: £25,000) higher/lower. 

The Group has not entered into forward currency contracts.

Note 1: These options were issued under the Non-Executive Directors’ Scheme and were subject to clinically 
related performance targets. 

Note 2: With the exception of 388,400 options held by current and former Executive Directors, these options 
were issued subject to performance conditions. These performance conditions may be market related or relating 
to clinical, scientific or commercial targets. Certain options issued from 2018 on were issued as a parallel option, 
exercisable either as a tax-advantaged option (with an exercise price equal to the market price on the date of 
grant) or as a non-tax advantaged option (with an exercise price of one pence). 

Note 3: These options were issued under the Group’s 2016 Non-Executive Share option Scheme. They vest 
over three years on a straight-line basis and with the exception of 750,000 options held by Mr Iain Ross, they 
carry no performance conditions. 750,000 of the options held by Mr. Ross are subject to share price based 
performance targets.

* Certain of these non-tax advantaged options were issued in parallel with tax advantaged CSOP options, either 
of which lapses upon the exercise of the other.

The assumed vesting period is four years. No lapses are assumed until they take place. Assumed volatility is 
based on historical experience up to the date of the grant.

Glossary of Scientific Terms

Adeno associated virus (AAV): 
AAV based vectors are small and are generally administered directly to patients into target tissues or into the blood. 

They allow expression of the therapeutic protein in cells that generally do not divide such as in the liver, the brain 
or eye. 

Allogeneic: 
Where a tissue donor and recipient of the cells are from different individuals. 

CAR-T/CAR-NK Cells: 
These are T-cells or NK cells that have been modified or engineered to produce proteins on their surface called 
chimeric antigen receptors (CARs). CAR-T cells main use is as a cancer therapy. 

Cell line: 
A well characterised cell culture that has been demonstrated to be consistent. Cell lines may comprise a family of 
cells isolated from a single tissue or organ, or may be clonally derived from a single ancestor cell. 

Cell therapy: 
A process by which healthy cells are introduced into a tissue or an organ to reconstruct or promote regeneration in 
order to treat disease. 

CMC: 
To  appropriately  manufacture  a  pharmaceutical  or  biologic  product,  specific  manufacturing  processes,  product 
characteristics and product testing must be defined in order to ensure that the product is safe, effective and consistent 
between batches. These activities are known as chemistry, manufacturing and controls (CMC). 

Cryopreservation: 
Maintenance of the viability of cells using agents to protect them from damage that can occur during cooling and 
storage at very low temperatures. 

Cytoplasm: 
Clear, gel-like substance that fills the inside of a cell but excluding the nucleus. 

Differentiation: 
Development of a stem cell into a more specialised cell type. 

DNA: 
Deoxyribonucleic acid (DNA) is a molecule that carries genetic information. 

Ectoderm: 
One  of  the  three  primary  germ  layers  formed  in  early  embryonic  development.  It  is  the  outermost  layer  and 
differentiates to form epithelial and neural tissues (spinal cord, peripheral nerves and brain). 

Endocytosis: 
A cellular process in which substances are brought into the cell. The material to be internalised is surrounded by an 
area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested material. 

Endoderm: 
The innermost of the three germ layers, or masses of cells (lying within ectoderm and mesoderm), which appears 
early in the development of an animal embryo.

Exosomes: 
These are nanoparticles secreted from many different types of cells, including the Company’s proprietary CTX stem 
cell line. They play a key role in cell-to-cell signalling. 

FDA: 
US Food and Drug Administration (FDA) is responsible for protecting the public health by assuring the safety, 
effectiveness, quality, and security of human and veterinary drugs, vaccines and other biological products, and 
medical devices.

Good Manufacturing Practice (GMP): 
Regulations, codes and guidelines to ensure that products are consistently produced and controlled according to 
quality standards appropriate to their intended use and as required by the product specification (GMP refers to current 
good manufacturing practice). 

Immortalised cell line: 
A population of cells from a multicellular organism, which would normally not proliferate indefinitely but, due to 
mutation, have evaded normal cellular senescence and instead can keep undergoing division. The cells can, therefore, 
be grown for prolonged periods in vitro. 

Immunogenicity: 
Immunogenicity can be stated as the ability of a substance to provoke an immune response or the degree to which 
it provokes an immune response. 

Immunosuppressants: 
An agent that can suppress or prevent the body’s immune response. 

Induced pluripotent stem cells (iPSC): 
iPSCs are cells that are reprogrammed back into an embryonic-like pluripotent state that enables the development 
of an unlimited source of any type of human cell needed for therapeutic purposes. 

In vitro vs in vivo: 
“In vitro” is in an artificial environment whereas “in vivo” is in a more natural environment (animal model). 

Lentivirus: 
Lentiviral based vectors integrate into patients’ cells and give rise to long term expression and can be used in both 
dividing and non-dividing cells. 

Ligand: 
A substance that forms a complex with a biomolecule to serve a biological purpose. 

Lipid nanoparticles: 
Lipid nanoparticles (LNPs) are a mixture of lipids manufactured in the laboratory to a specific size and density to mimic 
low-density lipoproteins, which allow them to be taken up into living cells. 

Mesoderm: 
One of the three primary germ layers in the very early embryo. The other two layers are the ectoderm (outside layer) 
and endoderm (inside layer), with the mesoderm as the middle layer between them. 

MHRA: 
Medicines and Healthcare products Regulatory Agency (MHRA) is an Executive agency of the Department of Health 
and Social Care in the United Kingdom which is responsible for ensuring that medicines and medical devices work 
and are acceptably safe.

miRNA: 
A short segment of RNA that regulates gene expression by binding to complementary segments of messenger RNA 
to down regulate the subsequent formation of protein. 

Monoclonal antibodies: 
Identical antibodies derived from a group of identical cloned cells or from an expression vector. Monoclonal antibodies 
recognise only one kind of antigen, i.e. they bind to the same site on a protein. 

mRNA: 
Messenger RNA is a type of single stranded RNA that carries codes from the DNA in a cell’s nucleus to the sites of 
protein synthesis in the cell’s cytoplasm. One of the uses of synthetic mRNA is in the development of vaccines. 

Nano-sized:
