4basebioAnnual Report & Financial Statements 2023 Strategic Report2. At a glance

4basebio PLC is a Cambridge, UK, AIM 
quoted holding and service company for the 
4basebio group of companies (“the Group”), 
which includes manufacturing and research & 
development subsidiaries across Cambridge, 
UK and Madrid, Spain.

4basebio is a technology group, which is 
a market leader in the development and 
commercialisation of large scale manufacture of 
synthetic DNA as well as nanoparticle delivery 
solutions. The Group continues to expand its 
commercial platform. Its customers are active 
in the cell & gene therapy and vaccine markets, 
across mRNA therapeutics and vaccines, AAV, 
gene editing and DNA vaccines.

The Group‘s technology platforms offer its 
customers application specific product and 
performance benefits, with its synthetic DNA 
also benefitting from much faster turnaround 
times relative to incumbent plasmid DNA. 
It also continues to invest in research and 
development activities to further develop its 
platforms and expand its product offering, 
particularly focussed on different DNA 
modalities including single stranded and circular 
synthetic DNA constructs.

Performance

During the course of 2023, 4basebio 
continued to scale up its commercial 
activities alongside ongoing product 
innovation. The emphasis during the 
year was on its synthetic DNA platform, 
with the Group recognising revenue on 
approximately 25 customer projects 
including the sale of its first High Quality 
DNA; it also took receipt of orders for GMP 
(“Good Manufacturing Practice”) grade 
product due for delivery in 2024.

The manufacture and sale of GMP grade 
synthetic DNA is a significant milestone for 
4basebio with the receipt of GMP orders 
an important step. While the Group’s 
journey to GMP has not been without its 
challenges, it is pleasing to reflect on the 
significant progress made. Evidence of 
the Group’s development also came in the 
form of its client, HelixNano Technologies 
Inc., announcing in March 2024 approval 
of its mRNA vaccine product for first 
in human trials in Australia. 4basebio 
opDNA™ was used in manufacturing the 
vaccine.

The Group also continued to develop its 
non-viral delivery platform, Hermes™. As 
announced during the year, 4basebio 
received grant funding from the Bill & 
Melinda Gates Foundation to pursue a 
research program to further advance its 
nanoparticle platform with enhanced 
thermostability for use in infectious 
disease vaccine applications.

Thermo-stability was an important 
consideration in the use of mRNA vaccines 
used during the Covid-19 epidemic. 
Those vaccines required -80C freezer 
storage to remain effective, presenting 
significant logistical challenges and 
cost considerations in the distribution of 
vaccines for pandemic response.

Preliminary findings demonstrate the 
Hermes™ product offers superior particle 
stability at higher temperatures, a 
commercially significant consideration 
in the context of meeting future vaccine 
demands, particularly in countries where 
cold supply chain logistics are challenging.

Alongside these commercial 
developments, the Group continues 
to invest in its intellectual property. 
During 2023 and early 2024, six new 
patent applications were filed and this is 
expected to continue. The Group now has 
17 patent families around its DNA platform 
and a further four patent families centred 
on its Hermes™ technology.

It is important that the Group acts to 
protect its intellectual property. As a 
result it has pursued legal action in Spain 
to protect against infringement and/
or misappropriation of its intellectual 

4

property. This has led to belated counter 
claims during the year which the Board 
and its legal advisors consider unfounded 
and without merit and is further described 
in note 26 to the financial statements.

which it can share with customers. It also 
means that 4basebio understands how its 
products will perform in the hands of its 
customers, a key consideration in meeting 
customer expectations.

With the objectives outlined above, the 
Group continued to invest during 2023 
with a resultant net loss for the year of 
£7.7 million.

Strengthening the Group’s commercial, 
client onboarding and operations teams 
was an important focus in the year, with 
overall headcount of 84 at year end.

The Board is pleased with the commercial 
progress made during 2023 and believes 
4basebio is well placed to grow revenues 
strongly in 2024. Nevertheless, 4basebio 
will remain loss making during 2024 
and the Group will utilise its loan facility 
with 2Invest AG, a major shareholder 
and former parent company, to fund its 
activities.

Strategy
4basebio’s principal objective is to 
become the leading provider of synthetic 
DNA products and non-viral delivery 
technology for the cell & gene therapy 
and vaccines markets. The Board believes 
the Group is well placed to do this, with 
a combination of a uniquely flexible 
synthetic DNA technology alongside its 
nanoparticle platform, a key competitive 
differentiator.

The flexibility in its DNA platform has 
facilitated the development of application 
specific products, which offer valuable 
performance benefits over alternative 
solutions. The overall objective is to 
continue developing and commercialising 
the most efficient and highest performant 
DNA products for each application.

An excellent example of this is supply of 
DNA for mRNA production; for this market, 
4basebio manufactures and supplies the 
requisite linearised open ended DNA, its 
opDNA™, required for in vitro transcription, 
the process of converting DNA into 
mRNA. This compares highly favourably 
with other products which require a 
further step of linearisation (in the case of 
plasmid DNA) or de-ending (in the case of 
alternative synthetic DNA).

Alongside this, the Group has also 
focussed on developing internal 
application relevant expertise, enabling 
the preparation and provision of data 
packages for prospective clients 
highlighting the benefits of 4basebio 
products in their specific field of 
application.

As a result, the Group has generated a 
breadth of highly relevant commercial data 

The Group continues to focus on 
working with each customer along their 
journey from research use through 
high quality batches and eventual GMP 
grade synthetic DNA. As the customer 
progresses, so does the requirement 
for both higher quality and quantity of 
product. As customers advance through 
their therapeutic development programs, 
the Group expects significant revenues to 
be generated from these projects.

Share Price
The share price opened the year at 
710 pence and softened during the course 
of the year to recover in November and 
December, to close at 680 pence. Trading 
volumes during the year represented 
approximately 4% of shares in issue, with 
a typical daily trading volume of 2,270 
shares

At year end, approximately 70% of 
the Company’s shares were closely 
held between the Company’s largest 
shareholders and Board directors. Whilst 
the Board has limited visibility on holdings 
below the reporting threshold of 3%, 
given shares are typically held in nominee 
accounts, the Board believes that a 
significant portion of the remaining shares 
is owned by long term shareholders.

People and Culture
As an innovative life sciences Group, 
4basebio is science led, with over three-
quarters of its workforce holding scientific 
degrees. This has facilitated the rapid 
development of the Group’s technology 
platforms, as well as commercial and 
manufacturing teams.

The Group strives to maintain an open, 
informal and supportive organisational 
culture. With the growth in headcount, 
maintaining the Group’s core values 
becomes ever more important and 
is a focus of staff at all levels of the 
organisation.

The Board would like to thank all staff for 
their commitment and dedication over the 
past year which has been instrumental in 
4basebio’s continued progress.

4basebioAnnual Report & Financial Statements 2023 Strategic Report4. Business model

Value Drivers

The business is focussed on developing and exploiting its portfolio of 
intellectual property by producing and commercialising application specific 
products underpinned by its technology. While the Group’s primary aim is the 
commercial exploitation of its technologies, the Board considers its intellectual 
property to have significant value in its own right.

The Group expects over time to develop a substantial contract manufacturing 
business, primarily supplying DNA for a range of customer applications within the 
cell & gene therapy and vaccine markets. The Group further expects that revenues 
will start to grow significantly as more of its clients progress towards GMP clinical 
product and eventually GMP commercial product.

In-house development
The Group has consistently adopted an in-house 
development approach, ensuring it has the expertise 
to develop and improve its products and technologies 
progressing into the manufacture and sale of those products. 
This has been complemented with in-house application 
validation and client onboarding teams which has provided 
a deep understanding and confidence about 4basebio’s 
product performance.

As a result, the Group has over time built up considerable 
expertise across all aspects of its business from research and 
development through to final manufacture and sale.

Technology Platforms
The Group continues to seek to exploit its complementary 
technology platforms in synthetic DNA and non-viral vectors. 
While research and development, commercialisation and 
revenues from these technologies are progressing along 
different timescales, many customers express an interest 
in both payload and delivery solutions demonstrating the 
commercial synergies of the platforms.

The revenue generation models of the two parts of the 
business may diverge over time, with DNA revenue stemming 
from a contract manufacturing business model, while non-viral 
delivery is more likely to use a fee-for-service and licensing 
model in due course.

55

4basebioAnnual Report & Financial Statements 2023 Strategic ReportStrategic Report5. Markets

4basebio operates in the cell & gene therapy and vaccines markets, supplying its synthetic DNA and delivery platform products 
and technologies as key components of the eventual therapy or vaccine its customers are developing.

The Group has identified several market segments where it believes its products are highly relevant:

Market

Market Scale

4basebio Offering

AAV and Lentivirus manufacture for use in 
gene therapies and vaccines

The viral vector manufacturing market size 
is estimated to be worth USD $1.5 billion in 
2023 and is projected to reach USD $5.5 
billion by 2035, growing at CAGR of 11% 
during the forecast period 2023-2035.1

hpDNA™, double stranded linear DNA, 
covalently closed with single strand 
hairpins at the 5’ and 3’ ends. This

The mRNA Synthesis and Manufacturing 
Services Market Size is valued at USD $49 
billion in 2022 and is predicted to reach 
USD 51.6 billion by 2031 at a 0.8% CAGR 
during the forecast period for 2023-20312. 
Overall market growth is expected to be 
modest due to the decline in Covid vaccines 
but with strong uptake in other areas.

The global gene editing market size is 
estimated to reach around USD $29.93 
billion by 2032, increasing from USD $6.94 
billion in 2022.3

The global DNA vaccine industry generated 
$433 million in 2021 and is expected to 
grow at a CAGR of 6.18% during 2022-2028 
to reach US$ ~654 million in 2028.4

Therapy and vaccine non-viral payload 
delivery

The global cell and gene therapy market 
size surpassed USD 15.5 billion in 2022 and 
is estimated to be worth around USD 82 
billion by 2032, growing at a healthy CAGR 
of 18.3% between 2023 and 2032.5

opDNA™ is a partially opened, linear, 
double stranded DNA product. A 3’ 
open end DNA template is ideally suited 
for in vitro transcription processes for 
the production of mRNA for use in 
vaccines and therapeutics.

oeDNA™, or open ended DNA, is a 
linear, double stranded DNA product 
ideal for genome editing

hpDNA™, described above is highly 
suitable for this application, along 
with osDNA™, or open stabilized DNA, 
a product incorporating nucleotide 
modifications within the DNA backbone. 
This feature not only provides resistance 
to exonuclease degradation but enables 
tuning of the immunostimulatory 
properties of the construct, making 
osDNA™ ideally suited for DNA vaccine 
applications.

The Hermes™ proprietary delivery 
platform for nucleic acid and protein 
payloads appears to offer an enhanced 
thermo-stable alternative to traditional 
lipid based delivery systems presently 
used. Like those lipid based systems, 
the particles have low immunogenicity, 
enabling repeat dosing strategies, 
unlike viral vectors.

4basebioAnnual Report & Financial Statements 2023 Strategic ReportStrategic Report6. Strategic goals 

As noted, 4basebio’s overall strategic objective is to become 
a leading supplier of synthetic DNA and non-viral vectors 
for the cell & gene therapy and vaccines markets and, at 
the same time, secure wide adoption of these technologies 
across these markets.

In the near term, the Group will continue to invest in the 
development of its technology platforms, continuing to 
demonstrate the flexibility and application specific benefits 
of those technologies and strengthening its patent portfolio.

In addition, 4basebio will establish contract manufacturing 
capabilities underpinned by the planned MHRA certification 
of its clean rooms for GMP manufacture.

The near term objective is to grow revenues to reach 
break-even and subsequent profitability; the timing of this 
is dependent on revenue growth as well as discretionary 
decisions around levels of research and development spend 
which the Group will continue to make.

4basebioAnnual Report & Financial Statements 2023 Strategic Report7. Key performance indicators

The Board monitors the progress towards the Group’s objectives through 
the assessment and review of operational plans, achievement of internal 
development milestones and results from activities undertaken with customers 
and partners.

Key indicators for the business are as follows:

Loss for the year:
Description: The Group’s loss for the financial year measures 
its overall financial performance during the period.

Performance: The Group expects to incur losses whilst 
investment in the business outpaces revenues. In the near 
term, the Group expects to reach break-even and profitability.

Revenues and Projects:
Description: The number of projects measures the long term 
trend in overall customer acquisition and revenue growth. 
Group revenues measure its progress in securing market and 
commercial validation.

Intellectual Property:
Description: Patent applications offer an indication of the 
progress in research and development activities of the Group 
and the value inherent in its technology platforms.

Performance: The Group expects strong revenue growth 
in 2024 compared to 2023. The expectation is to onboard 
significantly more projects, whilst also producing more HQ 
and GMP grade material than the previous year. Scheduling 
of projects and consequent revenue recognition is however 
dependent on customer planning, so the precise timing of 
revenues remains difficult to predict.

Performance: The Group now maintains 21 patent families, with 
further filings anticipated during 2024.

Cash flows:
Description: Given the funding requirements of the business to 
ensure successful commercialisation, the availability of cash is 
a key metric.

Performance: The Group closely monitors its cash position 
to ensure that its activities are developing as expected and 
that 4basebio continues to have available funding for the 
foreseeable future.

Employees:
Description: The Group uses headcount as a measure of 
investment in its activities and its underlying commercial 
capabilities.

The Group budgets carefully and is mindful of the available 
cash resources. The Group will continue to draw on the 2Invest 
AG facility as part of its cash management plans in 2024.

Performance: The Group will continue to build out its 
headcount during 2024, with headcount expansion expected 
to slow from 2025 onwards.

4basebioAnnual Report & Financial Statements 2023 Strategic ReportStrategic Report8.  Principal risks and uncertainties 

and risk management 

8.1  Risk management framework

The management of risk is a key responsibility of the Board of Directors. The Board ensures that the key risks are 
understood and appropriately managed in light of the Group’s strategy and objectives, and that an effective internal risk 
management process, including internal controls, is in place to identify, assess, minimise and manage significant risks.

The Audit Committee oversees risk management on behalf of the Board and the Group’s risk management policy and 
procedures to ensure they remain relevant. The key policy objectives include:

• 

• 

• 

establishing the importance of risk management in the successful operation of the business;

ensuring that the risk tolerances of the Board are fully understood by senior executives;

understanding the business risks that the Group faces and ensuring that they are appropriately managed or 
mitigated in line with the risk tolerances of the Board.

8.2  Principal risks

Risk description

Potential impact

Mitigation

Failure to protect intellectual property If the Group’s patents are successfully 

challenged or the patent portfolio is 
insufficient to protect the key commercial 
benefits of its products, this may 
significantly diminish the value of the 
Group’s intellectual property and therefore 
the valuation of the Group.

Commercialisation of technology is 
slow or delayed

If the Group is slow in commercialising 
its technology, the opportunity to grow 
revenues or realise value may be restricted 
by competitors or alternative technologies 
which may emerge. This would diminish the 
value of 4basebio.

The Group constantly monitors its 
patents and potential challenges and 
retains patent lawyers for the purpose 
of maintaining existing patents and filing 
new patents.
The Group also monitors the publication 
of new patent applications which 
may directly affect its own intellectual 
property and has and will take action 
where it considers those applications 
conflict with 4basebio intellectual 
property.

The Group constantly reviews its 
programs with a view to ensuring 
progress is as swift as possible. This 
includes collaborations with key 
partners.
The Group recognises the urgency in 
commercialising its technology, which 
has led to establishment of its client 
onboarding, manufacturing and quality 
assurance teams, alongside its business 
development activity.

Access to funding to support strategic 
objectives

The Group requires near term funding in 
order to pursue its strategic objectives until 
such time as the Group reaches break-even 
or an alternative valuation event.

The Group monitors its cash position 
very closely and will draw on the 2Invest 
AG facility over the course of 2024 and 
beyond.

4basebioAnnual Report & Financial Statements 2023 Strategic Report9.  Chief Executive Officer’s 

statement

9.1  Synthetic DNA platform
The demand for DNA continues to 
grow, with compound annual growth 
rate expected to exceed 20% for the 
foreseeable future. The market for DNA 
is expected to reach approximately 
$15bn by 2034, presenting an enormous 
opportunity for synthetic DNA to acquire 
market share, given the benefits it 
presents over the incumbent plasmid 
DNA.

There is clear momentum building in 
the adoption of synthetic DNA across 
various applications. During 2023 and 
early 2024, several announcements were 
made across the synthetic DNA market 
on the progression of the technology into 
clinical programs. This included 4basebio 
announcements relating to HelixNano 
Technologies, Inc. and the supply of HQ 
and GMP grade synthetic DNA into a tier 
one pharma company’s vaccine program.

It is clear that a key consideration for 
many customers is the speed of delivery, 
with synthetic DNA able to be supplied 
in a matter of weeks. Additionally, there 
are application specific product and 
performance benefits that 4basebio’s 
synthetic DNA offers, emphasising the 
significance of the platform flexibility.

The manufacture of mRNA via in vitro 
transcription or IVT, for example, is also 
an entirely synthetic process, so the 
adoption of synthetic DNA in this market 
is a natural progression. Meanwhile, for 
AAV production, the use of 4basebio 
synthetic DNA mitigates the risk of 
reverse packaging of plasmid backbone 
into viral vectors, a significant challenge 
for this market.

4basebio is now very focussed on its 
commercial development following the 
construction of its clean rooms. The 
Group is engaged with a multitude of 
clients requiring GMP in the near term, 
with the expectation that this level of 
demand will continue to grow as the 
Group secures its GMP certification and 
continues to supply product into clinical 
trials.

Alongside this, as in previous years, 
4basebio sees significant future value 
in continued innovation, both through 
development of intellectual property 
and bringing novel products to market. 
The Group will continue to invest into 
research and development alongside 
its commercial activities, including client 
onboarding, business development and 
project management capabilities.

This approach has enabled the Group to 
progress from the production of research 
grade product at nanogram scale 
(1 billionth of a gram) to clinical grade 
product at multi-gram scale in a matter of 
a few years. The Board expects this rate 
of progress to continue with appropriate 
investment in the Group’s capabilities.

The evolution of the Group since its 
admission to AIM in February 2021 has 
been profound and it is very satisfying 
to reflect on the progress made to date. 
The Board believes that 4basebio is now 
on the cusp of strong commercial growth 
and 2024 promises to be a very exciting 
year.

9.2  Non-viral delivery platform
The Group continues to invest in the 
development of the platform. The 
enhanced particle stability is a potentially 
highly significant commercial step for 
Hermes™ and with the support of the Bill 
& Melinda Gates Foundation, platform 

development has been expedited.

Hermes™ is being considered by 
customers as an alternative to 
conventional lipid nanoparticles, 
electroporation or viral vectors. The 
Hermes™ platform remains early in its 
development, but there are several very 
promising avenues to pursue.

The near-term objectives include the 
continued in vivo evaluation of particle 
formulations for a range of applications 
including vaccines, cancer therapy and 
other types of gene therapy, as well as 
completion of the initial Bill & Melinda 
Gates Foundation project.

9.3  Outlook
The Group expects to strongly grow 
its revenues in 2024, primarily through 
the sale of synthetic DNA. While the 
group has gained significantly improved 
commercial visibility during the course 
of 2023 and early 2024, a level of 
uncertainty remains around the timing 
of near-term revenue, in particular 
those projects requiring High Quality 
or GMP grades of material, given the 
dependency on clients’ development 
timelines.

Alongside the anticipated commercial 
progression, 4basebio will continue to 
invest in its technologies and commercial 
development during 2024. By the 
end of the year, the Group expects to 
have in excess of 100 staff, which it 
considers a strong foundation on which 
to further expand its manufacturing and 
commercial activities.

The Group expects to continue to incur 
operating losses and cash outflows over 
the coming year; the Board remains 
confident these steps will provide strong 
growth in overall shareholder and 
stakeholder value.

4basebioAnnual Report & Financial Statements 2023 Strategic ReportStrategic Report10. Financial Review

Introduction

10.1 
The Group recorded a loss for the 
year of £7.7 million (2022: £5.2 million), 
consistent with its internal budgeting 
and closed the year with £3.1 million 
cash on hand, having utilised the 
2Invest AG loan facility during the year.

10.2  Revenues
Revenues were £506k for the year 
(2022: £268k), with a doubling of DNA 
and Hermes™ sales against the previous 
year; legacy revenue sales from Spain 
represent less than £100k of overall 
revenues in the year.

10.3  Cost of sales
Cost of sales for the year was £166k 
(2022: £29k) and comprises primarily 
labour, materials and overheads 
associated with sales of synthetic DNA 
and non-viral vectors, along with the 
amortisation of previously capitalised 
development costs associated with the 
products sold from 4basebio S.L.U..

10.4  Sales and marketing
Sales and distribution expenditure 
was £586k for the year (2022: £245k), 
reflecting ongoing investment in the 
Group’s business development and 
project management teams.

10.5  Administration
Administration expenditure was 
£3.3 million for the year (2022: 
£2.7 million) reflecting headcount 
increases during year as well as general 
scaling of the business.

10.6  Operations
Operations expenditure was £1.4 million 
for the year (2022: £928k), again 
reflecting the additional investment 
in headcount, property and overall 
resources to support the Group’s 
progression towards GMP manufacture.

10.7  Research and Development
Total expenditure for the year was 
£3.6 million for the year (2022: 
£2.1 million) in addition to capitalised 
development costs of £0.6 million 
(2022: £0.5 million) in relation to 
platform development in Spain. The 
growth in expenditure was across 
all R&D functions including platform 
development, client onboarding and 
application validation teams.

10.8  Tax
The Group is loss making and no 
deferred tax assets have been 
recognised in respect of tax loss 
carry forwards due to the inherent 
uncertainty of recovery. Claims for 
tax credits in the UK and Spain have 
been recognised, totalling £0.7 million 
(2022: £0.8 million), with the reduction 
reflecting the new R&D tax credit 
regime in the UK.

12

4basebioAnnual Report & Financial Statements 2023 Strategic Report10.11  Going Concern
As the Group continues to invest in its 
activities and sustain cash outflows, the 
Board has considered the adequacy of 
available funds to meet the needs of 
the business for at least 12 months from 
the date of approval of the financial 
statements. The Board of Directors is 
satisfied that the Group has adequate 
cash resources through a combination 
of cash on hand and continued support 
from 2Invest AG.

10.12 Financial Outlook
During the course of 2024, the Group 
expects to significantly improve 
revenues in comparison with 2023 
primarily from synthetic DNA product 
sales. Nevertheless the Group expects 
to continue to incur operating losses for 
the year and will draw on the 2Invest 
AG facility during the period.

10.9  Balance Sheet
Total assets stood at £11.9 million 
(2022: £11.7 million). Cash on hand was 
£3.1 million, down from £4.4 million 
in 2022. Total non-current assets 
increased to £6.9 million from £5.8 
million reflecting additions in property 
and equipment and intangible assets. 
Current assets were £5.0 million 
(2022: £5.9 million), reflecting the cash 
outflows during the year; this included 
other assets of £1.5 million (2022: 
£1.4 million) comprising primarily R&D 
tax credits and short term deposits. 
Total liabilities were £12.4 million (2022: 
£4.6 million), reflecting the funding of 
business operations during the year 
through drawdowns under the 2Invest

4basebioAnnual Report & Financial Statements 2023 Strategic ReportStrategic Report11. Section 172 statement

The Group employed between 61 and 
84 staff during 2023. The executive 
directors interact daily with employees. 
Management has implemented 
employee policies and procedures 
which are appropriate for the size of the 
Group. 

As a relatively small organisation the 
Group’s impact on the community 
and the environment is modest but 
the Board endeavours to ensure that 
the business acts ethically and in an 
environmentally conscious manner. 

The strategic report was approved on 
4 June 2024 by order of the Board.

Heikki Lanckriet 
Chief Executive Officer 
4 June 2024

Under s172 of the Companies Act 
2006 the Directors have a duty to 
act in good faith in a way that is 
most likely to promote the success 
of the Company for the benefit of its 
members as a whole, having regard to 
the likely consequences of decisions 
for the long term, the interests of the 
Company’s employees, the need 
to foster relationships with other 
key stakeholders, the impact on the 
community and the environment, 
maintaining a reputation for high 
standards of business conduct, and the 
need to act fairly as between members 
of the Company. 

Key decisions made by the Board 
during 2023 related primarily to 
Company’s operating activities and 
allocation of expenditure across 
operations, research and development 
and commercial activity, in particular 
increases in headcount across those 
functions.  The Board considers these 
decisions to be in the best long-term 
interests of shareholders.

Approximately 70% of the Company’s 
shares are held by five investors, which 
include the CEO, CFO and one non-
executive director, Joe Fernandez. The 
executive directors and other members 
of the Board communicate from time 
to time with other shareholders and 
have a good understanding of their 
interests. The executive directors meet 
regularly with other shareholders, both 
institutional and private, to explain 
and discuss the Group’s strategy and 
objectives and to understand the 
interests of smaller shareholders in the 
Company. The Board recognises its 
responsibility to act fairly between all 
shareholders of the Company.

provided in the Directors’ remuneration report on pages 19 
and 20. 

2.4.  Engagement with shareholders 

The Company endeavours to communicate with stakeholders 
through a number of channels. Senior management and, if

on a regular basis. Management also frequently holds

non-shareholders. In addition, management prepares

2.1.1.  The role of the Board
The Board is responsible for leading and controlling 
the activities of the Group, with overall authority for the 
management and conduct of the Group’s business, together 
with its strategy and development. The Board is also 
responsible for ensuring the maintenance of a sound system 
of internal control and risk management (including financial, 
operational and compliance controls), reviewing the overall 
effectiveness of controls and systems in place, the approval 
of the budget and the approval of any changes to the capital, 
corporate and/or management structure of the Group.

In 2023 the Board held three formal Board meetings with 
additional ad hoc meetings as required. A full briefing pack is 
circulated to the Board for review prior to each meeting. The 
Board delegates authority as appropriate to its committees and 
members of the Group’s management team.

AIM-quoted companies are required to apply a recognised 
corporate governance code. The Company has adopted the 
Quoted Companies Alliance Corporate Governance Code 
(the “QCA Code”).

2.2.  Accountability 

2.2.1.  Composition of the Audit Committee 
The Audit Committee is comprised of Tim McCarthy, Pilar de 
la Huerta, Hansjörg Plaggemars and Joe Fernandez. Both 
Tim McCarthy and Pilar de la Huerta are considered to be 
independent Non-Executive Directors. Hansjörg Plaggemars 
is the CEO of 2Invest AG, a significant shareholder in 4basebio 
PLC and hence is not considered independent. Joe Fernandez 
is a significant shareholder in 4basebio PLC and hence is 
not considered independent. Tim McCarthy is Chair of the 
Committee and is considered to have recent relevant financial 
experience being a qualified accountant and having previously 
held the role of CFO in both private and listed companies. The 
Committee has written terms of reference, which are available 
for inspection on request to the Company Secretary. The 
activities of the Audit Committee, including those in relation to 
the Group’s external auditor, are described in the audit and risk 
report on page 18.

2.2.2. Risk management and internal control 
The Board has overall responsibility for the adequacy of the 
Group’s internal control arrangements and consideration of its 
exposure to risk. It approves and adopts the annual update to 
the Group’s risk management plan, following recommendations 
made by the Audit Committee. The Directors have assessed the 
principal risks facing the Company and actions taken to mitigate 
them on page 10 of the annual report.

3. Audit and Risk Report 

3.1.  The Audit Committee 

The Audit Committee’s responsibilities include: 

• 

Oversight of the risk management framework and 
regular risk reviews.

•  Monitoring of the financial integrity of the financial 

statements of the Group and the involvement of the 
Group’s auditor in that process.

• 

• 

Reviewing the effectiveness of the Group’s internal 
controls and risk management systems and overseeing 
the process for managing risks across the Group, 
including review of the Group’s corporate risk profile; and

that an effective system of internal financial control is 
maintained.

The Audit Committee met twice during the year with all 
members in attendance.

The Audit Committee also reviewed and approved 
for publication the Annual Report for the year ended 
31 December 2022 and the Interim Report for the half year 
ended 30 June 2023.

3.3.  External audit 

The Group’s external auditor, Crowe LLP, is engaged to provide 
its independent opinion on the Group’s financial statements. 
The Senior Statutory Auditor for 2023 was Mr Stephen Bullock. 
The Audit Committee approves any non-audit services provided 
by the external auditor, with consideration to the threats posed 
to independence and safeguards in place.

3.4.  Internal audit 

The Committee is of the opinion that an internal audit function 
is not currently appropriate for the Group given its stage of 
development. The Committee will continue to review the 
appropriateness of these arrangements.

3.2.  Activities of the Audit Committee 

In December 2023, the Committee reviewed the latest risk 
register which had been prepared by management and 
circulated to the full Board.

Key principle

To provide appropriate alignment with investors’ expectations in 
relation to the Company’s strategy and outcomes.

Executive Director remuneration was approved by the 
Remuneration Committee. The base salary and a performance 
related bonus of up 60% of basic salary for the Chief Executive 
Officer (CEO) and Chief Financial Officer (CFO) remained 
unchanged from 2022. 

On 25 January 2021, Heikki Lanckriet was awarded 238,000

share options at market price. As reported at the time, on

211,863 share options. On the same date, David Roth exercised 
his rights over 179,000 share options.

The Remuneration Committee met twice during the year with all 
members in attendance.

4.2.  Key remuneration principles

The Group’s remuneration arrangements for Executive 
Directors are based on the key principles set out below. The 
group has articulated how those principles are addressed within 
the remuneration policy.

How this reflects in the policy
The Executive Directors’ remuneration opportunity is a balance 
of fixed and performance based which is earned only subject to 
the satisfaction of performance conditions.
Performance conditions for the annual bonus and any share 
option schemes are set such as to align with shareholders’ 
interests.

On the same date, the Remuneration Committee resolved 
that the long-term incentivisation for senior management 
in the event of a future sale of the Company will comprise a 
cash bonus calculated as to a percentage of any future sale 
price achieved for the Company that exceeds £85 million. The 
quantum that would be awarded to Heikki Lanckriet and David 
Roth in the event of a sale of the Company is 0.52 per cent. 
and 0.44 per cent. of the sale price in excess of £85 million, 
respectively.

Responsibilities

 in respect of the annual report 

and the financial statements

6. Statement of Directors’ Responsibilities 
in respect of the annual report and the 
financial statements 

The Directors are responsible for preparing the annual report 
and the Group and parent company financial statements in 
accordance with applicable law and regulations. Company law 
requires the Directors to prepare Group and parent company 
financial statements for each financial year.

Under the AIM Rules of the London Stock Exchange they 
are required to prepare the Group financial statements in 
accordance with International Financial Reporting Standards as 
adopted by the United Kingdom (IFRSs as adopted by the UK) 
and applicable law and they have elected to prepare the parent 
company financial statements on the same basis.

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

In preparing the parent company financial statements, the 
Directors are required to:

• 

select suitable accounting policies and then apply them 
consistently;

•  make judgements and accounting estimates that are 

reasonable and prudent;

• 

state whether applicable UK Accounting Standards 
have been followed, subject to any material departures 
disclosed and explained in the financial statements; and 
prepare the financial statements on the going concern 
basis unless it is inappropriate to presume that the 
Company will continue in business.

In preparing the Group financial and parent company financial 
statements, International Accounting Standard 1 requires that 
Directors:

• 

• 

• 

properly select and apply accounting policies;

present information, including accounting policies, in a 
manner that provides relevant, reliable, comparable and 
understandable information;

provide additional disclosures when compliance with the 
specific requirements in IFRSs are insufficient to enable 
users to understand the impact of particular transactions, 
other events and conditions on the entity’s financial 
position and financial performance; and

•  make an assessment of the Company’s ability to 

continue as a going concern.

The Directors are responsible for keeping adequate accounting 
records that are sufficient to show and explain the Company’s 
transactions and disclose with reasonable accuracy at any 
time the financial position of the Company and enable them to 
ensure that the financial statements comply with the Companies 
Act 2006. They are also responsible for safeguarding the 
assets of the Company and hence for taking reasonable 
steps for the prevention and detection of fraud and other 
irregularities. The Directors are responsible for the maintenance 
and integrity of the corporate and financial information included 
on the Company’s website. Legislation in the United Kingdom 
governing the preparation and dissemination of financial 
statements may differ from legislation in other jurisdictions. 
Each of the serving Directors, whose names and functions are 
set out on pages 15 and 16, confirm that, to the best of their 
knowledge:

• 

• 

• 

the Financial Statements, prepared in accordance with 
the relevant financial reporting framework, give a true 
and fair view of the assets, liabilities, financial position 
and profit or loss of the Company and the undertakings 
included in the consolidation taken as a whole;

the Strategic report includes a fair review of the 
development and performance of the business and the 
position of the Company and the undertakings included 
in the consolidation taken as a whole, together with a 
description of the principal risks and uncertainties that 
they face; and

the Annual Report and Financial Statements, taken as 
a whole, are fair, balanced and understandable and 
provide the information necessary for shareholders 
to assess the Company’s position and performance, 
business model and strategy.

to the Members of 4basebio Plc

Independent Auditor’s Report 
to the Members of 4basebio Plc 

The requirement for additional shareholder support indicates 
the existence of a material uncertainty which may cast significant 
doubt about the Group and Company’s ability to continue as 
a going concern. The financial statements do not reflect any 
adjustments that would be necessary should the going concern 
basis not be appropriate.

In auditing the financial statements, we have concluded that 
the directors’ use of the going concern basis of accounting in 
the preparation of the financial statements is appropriate. Our 
evaluation of the directors’ assessment of the ability of the group 
and the parent company continue to adopt the going concern 
basis of accounting included the following procedures:

• 

• 

• 

• 

• 

• 

obtaining management’s assessment of going concern 
and the underlying financial projections which support that 
assessment

testing to ensure the mathematical accuracy of the model 
presented;

reviewing the assumptions used about future cash flows 
and timings;

confirming the existence of cash balance which will be 
relied on;

reviewing the appropriateness of the disclosures in the 
financial statements.

obtaining confirmation from 2Invest AG of its willingness to 
provide appropriate support arrangements for a period of 
at least 12 months from the date of approval of the financial 
statements.

The going concern assessment period used by the Directors was 
at least 12 months from the date of the approval of the financial 
statements. We assessed the appropriateness of the approach, 
assumptions and arithmetic accuracy of the model used by 
management when performing their going concern assessment.

We evaluated the Directors’ assessment of the group’s 
ability to continue as a going concern, including challenging 
the underlying data and key assumptions used to make the 
assessment.

Further details of the Directors’ assessment of going concern is 
provided in Note 2.

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

Opinion
We have audited the financial statements of 4basebio Plc 
(the “parent company”) and its subsidiaries (the “group”) for 
the period ended 31 December 2023 which comprise the 
Consolidated statement of profit or loss and other comprehensive 
income, the Consolidated and Company statements of financial 
position, the Consolidated and Company statements of changes 
in equity, the Consolidated statement of cash flows and notes 
to the financial statements, including a summary of significant 
accounting policies. The financial reporting framework that has 
been applied in the preparation of the group financial statements 
is applicable law and UK adopted International Accounting 
Standards (‘UK IFRS’). The financial reporting framework that has 
been applied in the preparation of the parent company financial 
statements is applicable law and United Kingdom Accounting 
Standards, including Financial Reporting Standard 101 Reduced 
Disclosures Framework (United Kingdom Generally Accepted 
Accounting Practice).

In our opinion:

• 

• 

• 

• 

the financial statements give a true and fair view of the 
state of the group’s and of the parent company’s affairs as 
at 31 December 2023 and of the group’s loss for the period 
then ended;

the group financial statements have been properly prepared 
in accordance with UK IFRS;

the parent company financial statements have been 
properly prepared in accordance with United Kingdom 
Generally Accepted Accounting Practice; and

the financial statements have been prepared in accordance 
with the requirements of the Companies Act 2006.

Basis for opinion
We conducted our audit in accordance with International 
Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our 
responsibilities under those standards are further described 
in the Auditor’s responsibilities for the audit of the financial 
statements section of our report. We are independent of 
the group in accordance with the ethical requirements that 
are relevant to our audit of the financial statements in the 
UK, including the FRC’s Ethical Standard as applied to listed 
entities, and we have fulfilled our other ethical responsibilities 
in accordance with these requirements. We believe that the 
audit evidence we have obtained is sufficient and appropriate to 
provide a basis for our opinion.

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 disclosures 
made in note 2.2 to the financial statements concerning the 
Group and Company’s ability to continue as a going concern. 
The Directors believe that the current levels of cash, amounts 
available for drawdown under the existing loan facility provided 
by 2Invest AG, a shareholder in the Company, and continuing 
support from 2Invest AG provide the Company and the Group 
with sufficient cash to meet their obligations as they fall due for at 
least twelve months following the date of this auditor’s report.

(continued)

Independent Auditor’s Report 
to the Members of 4basebio Plc (continued) 

Materiality
In planning and performing our audit we applied the concept of 
materiality. An item is considered material if it could reasonably 
be expected to change the economic decisions of a user of the 
financial statements. We used the concept of materiality to both 
focus our testing and to evaluate the impact of misstatements 
identified.

• 

• 

• 

£450,000 (2022: £380,000) is the group level of materiality 
determined for the financial statements as a whole, this has 
been determined based on approximately 7% of average 
loss before tax for FY22 and FY23. The objective of the 
group is to generate profit/loss, we determined that an 
profit based metric was the most appropriate to use for 
determining materiality.

£315,000 (2022: £304,000) is the group level of 
performance materiality. Performance materiality is used 
to determine the extent of our testing for the audit of the 
financial statements. Performance materiality is set based 
on the audit materiality as adjusted for the judgements 
made as to the entity risk and our evaluation of the specific 
risk of each audit area having regard to the internal control 
environment. Where considered appropriate performance 
materiality may be reduced to a lower level, such as, for 
related party transactions and directors’ remuneration.

£22,500 (2022: £19,000) is the group level of triviality 
agreed with the Audit Committee. Errors above this 
threshold are reported to the Audit Committee, errors 
below this threshold would also be reported to the Audit 
Committee if, in our opinion as auditor, disclosure was 
required on qualitative grounds.

The parent company materiality was assessed as £250,000 
(2022: £250,000) based on approximately 3% of net assets. 
As the parent company does not trade in its own right we 
determined that an asset based metric was the most appropriate 
to use for determining materiality. Parent company performance 
materiality was £200,000 (2022: £200,000) and triviality was 
£12,500 (2022: £19,000).

Overview of the scope of our audit
There are three significant components in the group in addition 
to the parent company, 4basebio S.L.U., 4basebio UK Limited and 
4basebio Discovery Limited. We audited the parent company, 
4basebio UK Limited & 4basebio Discovery Limited and our audit 
was conducted from the UK. Audit work on the significant non-UK 
component, 4basebio S.L.U., was carried out by a member of the 
Crowe Global international network as component auditor.

We engaged with the component auditor at all stages during 
the audit process and directed the audit work on the non-UK 
subsidiary undertaking. We directed the component auditors 
regarding the audit approach at the planning stage, issued 
instructions that detailed the significant risks to be addressed 
through the audit procedures and indicated the information we 
required to be reported.

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

We identified going concern as the only key audit matter. This 
is dealt with in ‘Material uncertainty relating to going concern’ 
above.

Our audit procedures in relation to these matters were designed 
in the context of our audit opinion as a whole. They were not 
designed to enable us to express an opinion on these matters 
individually and we express no such opinion.

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

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 such material inconsistencies or apparent material 
misstatements, we are required to determine whether there 
is a material misstatement in 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 in this regard.

Opinion on other matter prescribed by the 
Companies Act 2006
In our opinion based on the work undertaken in the course of our 
audit:

• 

• 

the information given in the strategic report and the 
directors’ report for the financial year for which the financial 
statements are prepared is consistent with the financial 
statements; and

the strategic report and the directors’ report have been 
prepared in accordance with applicable legal requirements.

(continued)

Independent Auditor’s Report 
to the Members of 4basebio Plc (continued)   

Matters on which we are required to report by 
exception
In the light of the knowledge and understanding of the group 
and the parent company and their environment obtained 
in the course of the audit, we have not identified material 
misstatements in the strategic report or the directors’ report.

We have nothing to report in respect of the following matters in 
relation to which the Companies Act 2006 requires us to report 
to you if, in our opinion:

• 

• 

• 

• 

adequate accounting records have not been kept by the 
parent company, or returns adequate for our audit have not 
been received from branches not visited by us; or

the parent company financial statements are not in 
agreement with the accounting records and returns; or

certain disclosures of directors’ remuneration specified by 
law are not made; or

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

Responsibilities of directors
As explained more fully in the directors’ responsibilities 
statement set out on page 23, the directors are responsible for 
the preparation of the financial statements and for being satisfied 
that they give a true and fair view, and for such internal control as 
the directors determine is necessary to enable the preparation 
of financial statements that are free from material misstatement, 
whether due to fraud or error.

In preparing the financial statements, the directors are 
responsible for assessing the group’s and the parent 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 parent company or to cease operations, or have 
no realistic alternative but to do so.

Auditor’s responsibilities for the audit of the 
financial statements
Our objectives are to obtain reasonable assurance about 
whether the financial statements as a whole are free from 
material misstatement, whether due to fraud or error, and to 
issue an auditor’s report that includes our opinion. Reasonable 
assurance is a high level of assurance, but is not a guarantee 
that an audit conducted in accordance with ISAs (UK) will always 
detect a material misstatement when it exists.

Misstatements can arise from fraud or error and are considered 
material if, individually or in the aggregate, they could reasonably 
be expected to influence the economic decisions of users taken 
on the basis of these financial statements.

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:

26

We obtained an understanding of the legal and regulatory 
frameworks within which the Group operates, focusing on 
those laws and regulations that have a direct effect on the 
determination of material amounts and disclosures in the financial 
statements. The laws and regulations we considered in this 
context were relevant company law and taxation legislation 
in the UK and Spain. Technical, clinical or regulatory laws and 
regulations which are inherent risks in the development of 
clinical products are mitigated and managed by the Board and 
management generally, in conjunction with expert regulatory 
consultants in order to monitor the latest regulations and planned 
changes to the regulatory environment.

We identified the greatest risk of material impact on the financial 
statements from irregularities, including fraud, to be the override 
of controls by management. Our audit procedures to respond to 
these risks included enquiries of management about their own 
identification and assessment of the risks of irregularities, sample 
testing on the posting of journals and reviewing accounting 
estimates for biases.

Owing to the inherent limitations of an audit, there is an 
unavoidable risk that we may not have detected some material 
misstatements in the financial statements, even though we have 
properly planned and performed our audit in accordance with 
auditing standards. We are not responsible for preventing non-
compliance and cannot be expected to detect non-compliance 
with all laws and regulations.

These inherent limitations are particularly significant in the 
case of misstatement resulting from fraud as this may involve 
sophisticated schemes designed to avoid detection, including 
deliberate failure to record transactions, collusion or the provision 
of intentional misrepresentations.

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

Use of our report
This report is made solely to the company’s members, as a body, 
in accordance with Chapter 3 of Part 16 of the Companies Act 
2006. Our audit work has been undertaken so that we might 
state to the company’s members those matters we are required 
to state to them in an auditor’s report and for no other purpose. 
To the fullest extent permitted by law, we do not accept or 
assume responsibility to anyone other than the company and the 
company’s members as a body, for our audit work, for this report, 
or for the opinions we have formed.

Notes to the financial statements 
For the year ended 31 December 2023 

1.  General information

4basebio PLC (the “Company” or “4basebio”) is registered in England and Wales with company number 13519889.

The Company is domiciled in England and the registered office of the Company is 25 Norman Way, Over, Cambridge CB24 5QE. 
4basebio PLC is the parent of a group of companies (together, “the Group”). The Group focusses on life sciences and in particular 
the development of synthetic DNA and nanoparticles suitable for inclusion in, or delivery of, therapeutic payloads for gene 
therapies and gene vaccines.

The Company trades on London Stock Exchange’s AIM market, having been admitted on 17 February 2021. The international 
securities number (ISIN) number for its AIM traded shares is GB00BMCLYF79; its ticker symbol is 4bb.l.

The consolidated financial statements of 4basebio PLC and its subsidiaries for the year ended 31 December 2023 were authorised 
for issue in accordance with a resolution of the directors on 4 June 2024.

2.  Accounting policies

2.1  Company
Basis of preparation
The Company’s financial statements of 4basebio PLC for the financial year ending 31 December 2023 have been prepared in 
accordance with the historical cost convention and in accordance with Financial Reporting Standard 101, Reduced Disclosure 
Framework (FRS 101) and the Companies Act 2006. Those financial statements present information about the Company as an 
individual entity. Accounting policies have been applied consistently throughout the year.

In preparing its financial statements the Company has taken advantage of certain disclosure exemptions conferred by FRS 101.

Therefore, these financial statements do not include:

 — certain comparative information as otherwise required by international accounting standards;

 — a statement of cash flows;

 — the effect of future accounting standards not yet adopted;

 — the disclosure of the remuneration of key management personnel; and

 — disclosure of intercompany transactions with wholly owned subsidiary companies.

In addition, and in accordance with FRS101 further disclosure exemptions have been adopted because equivalent disclosures are 
included in these consolidated financial statements and hence do not include Company only disclosures in respect of:

 — financial instruments;

 — fair value measurement

As permitted by Section 408 of the Companies Act 2006, the Company has not presented its own income statement. The loss for 
the financial year per the accounts of the Company was £1.3 million. The principal accounting policies adopted are set out below.

Investments in subsidiaries
Investments in subsidiaries and joint ventures are stated at cost less, where appropriate, provisions for impairment. The Company 
tests the investment balances for impairment annually or when there are indicators of impairment. 

Share-based payments
The fair value of employee share option plans is calculated at the grant date using the Black-Scholes model. The resulting cost is 
charged to the Company income statement over the vesting period. The value of the charge is adjusted to reflect expected and 
actual levels of vesting.

Financial instruments
Financial assets and financial liabilities are recognised in the Company balance sheet when the Company becomes party to the 
contractual provisions of the instrument.

2.2  Group
Basis of preparation
The consolidated financial statements of 4basebio UK PLC (or “the Group”) for the financial year ending 31 December 2023 have 
been prepared using UK adopted international accounting standards.

The consolidated financial statements comprise the results of 4basebio PLC, 4basebio S.L.U., 4basebio UK Limited and 4basebio 
Discovery Limited for the whole year.

The financial statements have been prepared on the historical cost basis. Historical cost is generally based on the fair value of the 
consideration given in exchange for goods and services. For calculation reasons, rounding differences of +/- one unit (£’000, % etc.) 
may occur in the information presented in these financial statements.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market 
participants at the measurement date, regardless of whether that price is directly observable or estimated using another valuation 
technique. In estimating the fair value of an asset or a liability, the Group takes into account the characteristics of the asset or 
liability if market participants would take those characteristics into account when pricing the asset or liability at the measurement 
date. Fair value for measurement and/or disclosure purposes in these consolidated financial statements is determined on such a 
basis, except for leasing transactions that are within the scope of IFRS 16.

The principal accounting policies adopted are set out below.

Going concern
The directors have, at the time of approving the financial statements, a reasonable expectation, taking into account the support 
from 2Invest AG, a shareholder in 4basebio PLC that the Company and the Group will continue as a going concern. As set out in 
note 22, the Company has a loan facility with 2Invest AG. In addition, 2Invest AG has provided to the Board of 4basebio PLC a 
letter confirming its willingness to support the Company, should the Company and the Group require working capital in addition 
to amounts available for drawdown under the existing loan facility for a period of at least 12 months from the date of approval of 
these financial statements, to enable the Company and the Group to continue to meet their obligations as they fall due. Thus, the 
directors continue to adopt the going concern basis of accounting in preparing the financial statements.

Additional support from 2Invest AG may be subject to certain conditions and therefore represents a material uncertainty in 
relation to going concern; such support having been made available by 2Invest AG to 4basebio PLC since its spin out in December 
2020. The financial statements do not reflect any adjustments that would be necessary should the going concern basis not be 
appropriate. 

Operating segments
Operating segments are presented using the ‘management approach’, where the information presented is on the same basis as 
the internal reports provided to the Chief Operating Decision Makers (‘CODM’), the board of directors. The CODM are responsible 
for the allocation of resources to operating segments and assessing their performance. For the years ended 31 December 2023 
and 31 December 2022, the Group comprised one operating segment.

Business combinations
The consolidated financial statements include 4basebio PLC and its subsidiaries over which the Company can exercise control. 
Control exists if 4basebio has a risk burden from or is entitled to fluctuating returns from its involvement in a company and it can 
also use its power of disposal over the associated company to influence these returns. In general, ownership of a majority of voting 
rights (direct or indirect) is presumed to result in control. The financial statements of subsidiaries to be included in the consolidated 
financial statements are included in the consolidated financial statements from the date on which the possibility of exercising 
control begins until the date on which the possibility of exercising control ends.

Revenue recognition
Revenue from contracts with customers is recognised at the point that control of the goods is transferred to the customer. This 
is generally the point of delivery. Recognition amount is the amount of the consideration that the Group will likely receive in 
exchange for these goods or services. The usual payment profile comprises an upfront payment of up to 50% at the time an order 
is placed with the balance settled 30 to 90 days following delivery. The Group has concluded that it acts as a principal in its sales 
transactions, as the Group usually has control over the goods or services before they are transferred to the customer.

The Group checks contracts with customers to see whether the contracts contain other commitments which represent separate 
performance obligations to which a part of the transaction price must be allocated (e.g. warranties).

34

heading 1heading 24basebioAnnual Report & Financial Statements 2023Financial StatementsNotes to the financial statements 
(continued) 

Leases
The Group as lessee
The Group assesses whether a contract is or contains a lease, at inception of the contract. The Group recognises a right-of-use 
asset and a corresponding lease liability with respect to all lease arrangements in which it is the lessee, except for short-term 
leases (defined as leases with a lease term of 12 months or less) and leases of low value assets (such as tablets and personal 
computers, small items of office furniture and telephones). For these leases, the Group recognises the lease payments as an 
operating expense on a straight-line basis over the term of the lease unless another systematic basis is more representative of the 
time pattern in which economic benefits from the leased assets are consumed.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, 
discounted by using the rate implicit in the lease. If this rate cannot be readily determined, the Group uses its incremental 
borrowing rate.

Lease payments included in the measurement of the lease liability comprise:

 — Fixed lease payments (including in-substance fixed payments), less any lease incentives receivable; and

 — Payments of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease.

The lease liability is presented as a separate line in note 22.

The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the 
effective interest method) and by reducing the carrying amount to reflect the lease payments made.

The Group remeasures the lease liability (and makes a corresponding adjustment to the related right-of-use asset) whenever:

 — The lease term has changed or there is a significant event or change in circumstances resulting in a change in the assessment 
of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments 
using a revised discount rate.

 — A lease contract is modified and the lease modification is not accounted for as a separate lease, in which case the lease liability 

is remeasured based on the lease term of the modified lease by discounting the revised lease payments using a revised 
discount rate at the effective date of the modification.

The right-of-use assets comprise the initial measurement of the corresponding lease liability, lease payments made at or before the 
commencement day, less any lease incentives received and any initial direct costs. They are subsequently measured at cost less 
accumulated depreciation and impairment losses

Right-of-use assets are depreciated over the shorter period of lease term and useful life of the right-of-use asset. If a lease transfers 
ownership of the underlying asset or the cost of the right-of-use asset reflects that the Group expects to exercise a purchase 
option, the related right-of-use asset is depreciated over the useful life of the underlying asset. The depreciation starts at the 
commencement date of the lease.

The Group applies IAS 36 to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss as 
described in the ‘Property, Plant and Equipment’ policy.

Foreign currencies
The functional currency of the Group is British Pounds.

In preparing the financial statements of the Group entities, transactions in currencies other than the entity’s functional currency 
(foreign currencies) are recognised at the rates of exchange prevailing on the dates of the transactions. At each reporting date, 
monetary assets and liabilities that are denominated in foreign currencies are retranslated at the rates prevailing at that date.

Exchange differences are recognised in profit or loss in the period in which they arise except for:

 — exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither 
planned nor likely to occur in the foreseeable future (therefore forming part of the net investment in the foreign operation), 
which are recognised initially in other comprehensive income and reclassified from equity to profit or loss on disposal or partial 
disposal of the net investment.

For the purpose of presenting consolidated financial statements, the assets and liabilities of the Group’s foreign operations 
(4basebio S.L.U.) are translated at exchange rates prevailing on the reporting date. Income and expense items are translated at the 
average exchange rates for the period, unless exchange rates fluctuate significantly during that period, in which case the exchange 

35

heading 1heading 24basebioAnnual Report & Financial Statements 2023Financial StatementsFinancial StatementsNotes to the financial statements 
(continued) 

rates at the date of transactions are used. Exchange differences arising, if any, are recognised in other comprehensive income and 
accumulated in a foreign exchange translation reserve.

The principal currency rates of the Group have developed as follows in relation to the British Pound (GBP/£):

Euro
US Dollar

Grants
Grants are not recognised until there is reasonable assurance that the Group will comply with the conditions attaching to them and 
that the grants will be received. Where grant funds are received in advance of satisfying conditions for recognising grant income, 
the grant is recognised as a short term liability. Grant income is recognised in other operating income.

On government loans advanced at a below-market rate of interest, the benefit is treated as a government grant, measured as the 
difference between proceeds received and the fair value of the loan based on prevailing market interest rates.

Retirement and termination benefit costs
Payments to defined contribution retirement benefit plans are recognised as an expense when employees have rendered service 
entitling them to the contributions. Payments made to state-managed retirement benefit plans are accounted for as payments to 
defined contribution plans where the Group’s obligations under the plans are equivalent to those arising in a defined contribution 
retirement benefit plan.

Short-term employee benefits
A liability is recognised for benefits accruing to employees in respect of wages and salaries, annual leave and sick leave in the 
period the related service is rendered at the undiscounted amount of the benefits expected to be paid in exchange for that service.

Liabilities recognised in respect of short-term employee benefits are measured at the undiscounted amount of the benefits 
expected to be paid in exchange for the related service.

Share-based payments
Employees (including senior executives) of the Group receive remuneration in the form of share-based payments, whereby 
employees render services as consideration for equity instruments (equity-settled transactions). The fair value of options granted is 
recognised as an expense of employment in the statement of comprehensive income with a corresponding increase in equity.

The fair value is measured at the date of grant and spread over the period during which the employees become unconditionally 
entitled to the options. The fair value of options granted under the share option schemes is measured using a Black Scholes model 
taking into account the performance conditions under which such options were granted. At each financial year end, the Group 
revises its estimate of the number of options that are expected to become exercisable based on forfeiture such that at the end of 
the vesting period the cumulative charge reflects the actual options that have vested, with no charge for those options which were 
forfeit prior to vesting. When share options are exercised the proceeds received are credited to equity.

Taxation
The income tax expense represents the sum of the tax currently payable and deferred tax.

Current tax
The tax currently payable is based on any taxable profit for the year. Taxable profit differs from net profit as reported in profit or 
loss because it excludes items of income or expense that are taxable or deductible in other years and it further excludes items 
that are never taxable or deductible. The Group’s liability for current tax is calculated using tax rates that have been enacted or 
substantively enacted by the end of the reporting period.

A provision is recognised for those matters for which the tax determination is uncertain but it is considered probable that there 
will be a future outflow of funds to a tax authority. The provisions are measured at the best estimate of the amount expected to 
become payable. The assessment is based on the judgement of accounting professionals and in certain cases based on specialist 
independent tax advice.

36

heading 1heading 24basebioAnnual Report & Financial Statements 2023Financial Statements 
Notes to the financial statements 
(continued) 

Deferred tax
Deferred tax is the tax expected to be payable or recoverable on differences between the carrying amounts of assets and liabilities 
in the financial statements and the corresponding tax bases used in the computation of taxable profit and is accounted for using 
the liability method. Deferred tax liabilities are generally recognised for all taxable temporary differences and deferred tax assets 
are recognised to the extent that it is probable that taxable profits will be available against which deductible temporary differences 
can be utilised.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer 
probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered.

Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised 
based on tax laws and rates that have been enacted or substantively enacted at the reporting date.

The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which 
the Group expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax 
liabilities and when they relate to income taxes levied by the same taxation authority and the Group intends to settle its current tax 
assets and liabilities on a net basis.

Current tax and deferred tax for the year
Current and deferred tax are recognised in the profit or loss, except when they relate to items that are recognised in 
other comprehensive income or directly in equity, in which case, the current and deferred tax are also recognised in other 
comprehensive income or directly in equity respectively. Where current tax or deferred tax arises from the initial accounting for a 
business combination, the tax effect is included in the accounting for the business combination.

Property, plant and equipment
Land and buildings held for use in the production or supply of goods or services or for administrative purposes, are stated in the 
statement of financial position at cost less any accumulated depreciation and accumulated impairment losses.

Freehold land is not depreciated.

Plant, machinery, fixtures and fittings are stated at cost less accumulated depreciation and accumulated impairment loss.

Depreciation is recognised so as to write off the cost or valuation of assets (other than freehold land and properties under 
construction) less their residual values over their useful lives, using the straight-line method, on the following bases:

Buildings  

5 per cent per annum

Plant and machinery 

10 per cent – 25 per cent per annum

Fixtures and fittings 

10 per cent – 30 per cent per annum

The estimated useful lives, residual values and depreciation method are reviewed at the end of each reporting period, with the 
effect of any changes in estimate accounted for on a prospective basis.

Right-of-use assets are depreciated over the shorter period of the lease term and the useful life of the underlying asset. If a lease 
transfers ownership of the underlying asset or the cost of the right-of-use asset reflects that the Group expects to exercise a 
purchase option, the related right-of-use asset is depreciated over the useful life of the underlying asset.

An item of property, plant and equipment is derecognised upon disposal or when no future economic benefits are expected to 
arise from the continued use of the asset. The gain or loss arising on the disposal or retirement of an asset is determined as the 
difference between the sales proceeds and the carrying amount of the asset and is recognised in profit or loss.

Internally-generated intangible assets – research and development expenditure
The amount initially recognised for internally generated intangible assets is the sum of the expenditure incurred from the date 
when the intangible asset first meets the recognition criteria listed below. Where no internally- generated intangible asset can be 
recognised, development expenditure is recognised in profit or loss in the period in which it is incurred.

37

heading 1heading 24basebioAnnual Report & Financial Statements 2023Financial StatementsFinancial Statements 
Notes to the financial statements 
(continued) 

Subsequent to initial recognition, internally generated intangible assets are reported at cost less accumulated amortisation and 
accumulated impairment losses, on the same basis as intangible assets that are acquired separately.

Intangible assets are generally recognised initially at cost. The cost of intangible assets acquired in business combinations is the 
fair value at the time of acquisition. With the exception of capitalised development costs and internally generated patents, no 
internally generated intangible assets are recognised in the consolidated statement of financial position of the Group. Instead, 
the corresponding expenses are recognised as expenses in the consolidated income statement in the period in which they were 
incurred. Development costs are only capitalised as intangible assets if the Group can demonstrate that the specific recognition 
criteria according to IAS 38.57 are met.

Research and non-capitalisable development costs are recorded as expenses in the period in which they are incurred and reported 
in a separate line in the consolidated income statement (“Research and non-capitalised development costs”).

For the purposes of subsequent measurement of intangible assets, IFRSs distinguish between intangible assets with finite and 
indefinite useful lives. The consolidated financial statements of the 4basebio Group only contain intangible assets with a finite 
useful life. These are amortised over their useful economic life and tested for possible impairment if there are indications that 
the intangible asset may be impaired. In the case of capitalised development costs, amortisation begins upon completion of the 
development phase and from the point at which the asset can be used. During the development phase, an annual impairment test 
is carried out. Amortisation is recognised for capitalised development costs within cost of sales and for all other intangible assets 
within the expense category that corresponds to the function of the intangible asset in the 4basebio Group. Depreciation periods 
and methods are reviewed at least at the end of each reporting period. If changes in the expected useful life or the expected 
pattern of consumption of future economic benefits embodied in an intangible asset necessitate changes in the amortisation 
method or amortisation period, these changes are treated as changes in accounting estimates and recognised prospectively in 
profit or loss for the period.

An intangible asset is derecognised either upon disposal or when no further economic benefit is expected from the continued 
use or sale of the recognised asset. Gains or losses arising from derecognition of intangible assets are measured as the difference 
between the net disposal proceeds and the carrying amount of the asset and are recognised in profit or loss in the period in which 
the intangible asset is derecognised.

The accounting and valuation methods applied to the intangible assets of the Group are summarised as follows:

  Patents and  Licences

Useful life
Amortisation method 

Type of asset

Finite
Amortised on a straight-line basis over the term 
of the licence
Acquired

Capitalised development costs
Finite
Amortised on a straight-line basis over the period of 
expected future sales from the related project
Internally generated

Patents and licences
The expenditure associated with the granting of a patent or licence is measured initially at purchase cost and are amortised on a 
straight-line basis over their estimated useful lives.

Impairment of property, plant and equipment and intangible assets
At each reporting date, the Group reviews the carrying amounts of its property, plant and equipment and intangible assets to 
determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the 
recoverable amount of the asset is estimated to determine the extent of the impairment loss (if any).

Recoverable amount is the higher of fair value less costs of disposal and value in use. In assessing value in use, the estimated 
future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the 
time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset is estimated to be less than its’ carrying amount, the carrying amount of the asset is reduced 
to its recoverable amount. An impairment loss is recognised immediately in profit or loss.

Inventories
Inventories are stated at the lower of cost and net realisable value. Cost comprises direct materials and, where applicable, direct 
labour costs and those overheads that have been incurred in bringing the inventories to their present location and condition. Cost 

38

heading 1heading 24basebioAnnual Report & Financial Statements 2023Financial StatementsNotes to the financial statements 
(continued) 

is calculated using the weighted average cost method. Net realisable value represents the estimated selling price less all estimated 
costs of completion and costs to be incurred in marketing, selling and distribution.

Financial instruments
Financial assets and financial liabilities are recognised in the Group’s statement of financial position when the Group becomes a 
party to the contractual provisions of the instrument.

Financial assets and financial liabilities are initially measured at fair value, except for trade receivables that do not have a significant 
financing component which are measured at transaction price. Transaction costs that are directly attributable to the acquisition or 
issue of financial assets and financial liabilities (other than financial assets and financial liabilities at fair value through profit or loss) 
are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition.

Financial liabilities and equity
Classification as debt or equity
Debt and equity instruments are classified as either financial liabilities or as equity in accordance with the substance of the 
contractual arrangements and the definitions of a financial liability and an equity instrument.

Equity instruments
An equity instrument is any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities. 
Equity instruments issued by the Group are recognised at the proceeds received, net of direct issue costs.

Financial liabilities
All financial liabilities are measured subsequently at amortised cost using the effective interest method. The effective interest 
method is a method of calculating the amortised cost of a financial liability and of allocating interest expense over the relevant 
period. The effective interest rate is the rate that exactly discounts estimated future cash payments (including all fees and points 
paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through 
the expected life of the financial liability, or (where appropriate) a shorter period, to the amortised cost of a financial liability.

Derecognition of financial liabilities
The Group derecognises financial liabilities when, and only when, the Group’s obligations are discharged, cancelled or have 
expired. The difference between the carrying amount of the financial liability derecognised and the consideration paid and payable 
is recognised in profit or loss.

Provisions
Provisions are recognised when the Group has a present obligation (legal or constructive) as a result of a past event, it is probable 
that the Group will be required to settle that obligation and a reliable estimate can be made of the amount of the obligation.

The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the 
reporting date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the 
cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows (when the effect 
of the time value of money is material).

When some or all the economic benefits required to settle a provision are expected to be recovered from a third party, a receivable 
is recognised as an asset if it is virtually certain that reimbursement will be received and the amount of the receivable can be 
measured reliably.

3.  Adoption of new and revised standards

The following new standards and amendments were mandatory for adoption for periods ending 31 December 2023. Changes to 
disclosure of accounting policies requiring disclosure of material policies has been reflected in note 2 to these financial statements. 
The remaining standards and amendments do not affect the Group: 

 — Disclosure of Accounting Policies (Amendments to IAS 1 and IFRS Practice Statement 2) 

 — Definition of Accounting Estimates (Amendments to IAS 8) 

 — Deferred Tax related to Assets and Liabilities arising from a Single Transaction (Amendments to IAS 12) 

 — International Tax Reform – Pillar Two Model Rules (Amendments to IAS 12) – Application of the exception and disclosure of  

that fact 

The Group has not early adopted any other standard, interpretation or amendment that has been issued but is not yet effective.

4.  Critical accounting judgements, estimates and assumptions

The following are the critical judgements, apart from those involving estimations (which are presented separately below), that the 
directors have made in the process of applying the Group’s accounting policies and that have the most significant effect on the 
amounts recognised in financial statements.

Capitalisation of development expenditure
The Group capitalises the costs of product development projects if the recognition criteria according to IAS 38.57 are met. The 
capitalisation of development costs is based on management’s assessment that the technical and economic feasibility has been 
demonstrated. This is generally the case when a product development project has reached a certain milestone in an existing 
project management model. For determining the amounts to be capitalised, management makes assumptions about the amount 
of expected future cash flows from the project, the discount rates to be applied and the timing of inflow of the expected future 
benefit. As at 31 December 2023 the carrying amount of capitalised development costs amounted to £2.1 million (31 December 
2022: £1.7 million).

Included in grant income are public loans received by 4basebio S.L.U which carry either a minimal or nil interest rate and are hence 
also referred to as soft loans. The benefit accruing to the Company from low interest loans has been accounted for as grant income. 
The fair value of loans received has been calculated on the basis of an arm’s length rate of interest of 4%, with imputed interest 
charges being recognised over the period of the loans.

The consequential difference between funds received and the underlying fair value of the loans has been recognised as deferred 
grant income within financial liabilities. This benefit is amortised over the life of each loan giving rise to grant income recorded in 
other operating income.

Tax reconciliation statement
The difference between the expected income tax expense and the income tax expense actually reported is shown in the following 
reconciliation. To determine the expected tax expenses, a weighted average UK and Spain tax rate of 23.7% was used for 2023 
(2022: 20%) and was multiplied by the loss before taxes.

The calculation of the basic and diluted earnings per share for continuing operations was based on the weighted average number 
of shares as determined above. The numerator is defined as result after tax from continuing operations. The average number of 
share options outstanding during the period was 653,771 (2022: 642,878) which have not been included in the calculation of the 
diluted Earnings per share because they would be anti-dilutive since the business is loss making.

18.  Trade receivables

Trade receivables do not bear interest and generally fall due within 30 to 90 days. An impairment on trade receivables for 
expected credit losses of £2k (2022: £1k) was recognised in 2023.

The default risk from receivables from customers is managed based on the guidelines, procedures and controls of the 4basebio 
Group for default risk management for customers. Outstanding receivables from customers are monitored regularly.

The need for impairment is analysed at each balance sheet date using an impairment matrix to determine the expected credit 
losses. The impairment rates are determined on the basis of the number of days past due for various customer segments (grouped 
together according to criteria such as geographic region, product type, customer type, and credit rating) with similar default 
patterns. The calculation includes the probability-weighted result, taking into account the interest effect as well as appropriate and 
reliable information on past events, current circumstances and expected future economic conditions available at the balance sheet 
date. Trade receivables are generally impaired if they are more than one year overdue and not subject to enforcement action.

The maximum default risk at the balance sheet date corresponds to the carrying amount of each class of financial assets reported. 
The 4basebio Group holds no collateral.

Authorised Share Capital
The Annual General Meetings of 14 June 2023 and 9 June 2022 conferred authority to the board of directors to issue additional 
8,623,629 and 8,211,648 ordinary shares of €1 each respectively, with such authority to expire on the earlier date of the next 
Annual General Meeting or 15 months following the previous Annual General Meeting.

3,695,841 of those shares (2022: 4,105,824 shares) were generally and unconditionally authorised pursuant to section 551 of the 
Companies Act 2006; a further 4,927,788 of those shares (2022: 4,105,824 shares) were generally and unconditionally authorised 
pursuant to section 560 of the Companies Act 2006. As part of such authorities totalling 8,623,629 shares (2022: 8,211,648), up to 
1,231,947 shares (2022: 1,231,747 shares) were also authorised to be issued pursuant to section 570 of the Companies Act 2006 for 
cash consideration and 1,231,947 shares (2022: 615,873 shares) were also authorised to be issued pursuant to section 570 of the 
Companies Act 2006 as part of an acquisition.

Share Premium
The share premium represents the excess of the capital contributions over and above the number of €1 par value shares issued to 
date.

Merger Reserve
The merger reserve arises from the spin out accounting as described in note 13 of the 2021 financial statements and in relation to 
the acquisition of 4basebio S.L.U and 4basebio Limited (now 4basebio UK Limited) by 4basebio UK Societas (now 4basebio PLC). 
The merger reserve represents the difference between the net equity of 4basebio UK Societas (now 4basebio PLC), the legal 
acquiror, and the net equity of 4basebio S.L.U. on the date of the reverse acquisition, 8 December 2020 as well as the net assets 
acquired of 4basebio Limited (now 4basebio UK Limited).

Capital Reserve
The capital reserve represents the capital contribution from 4basebio AG (now 2Invest AG) of £11.7million in 2020 along with the 
share-based payments accounting arising in 2023 and previous periods.

Foreign Exchange translation reserve
The reserve represents the movement in pounds arising on the translation of 4basebio S.L.U. from its functional currency, the Euro.

As disclosed in note 2, for the purpose of presenting consolidated financial statements, the assets and liabilities of the Group’s 
foreign operations (4basebio S.L.U.) are translated at exchange rates prevailing on the reporting date. Income and expense items 
are translated at the average exchange rates for the period. Exchange differences arising are recognised in other comprehensive 
income and accumulated in a foreign exchange translation reserve.

Profit and Loss reserve
The reserve represents historic losses from 4basebio S.L.U. prior to the 2020 spin out as explained in note 3 to the 2021 financial 
statements, along with consolidated losses arising since that date.

other operating income.

The loan facility with 2Invest is denominated in Euros and is for up to €23 million which can be drawn, with notice, at the discretion 
of 4basebio PLC until 31 October 2026. Interest is charged at 5% per annum on all loan amounts outstanding and compounds 
annually on all loan tranches outstanding. The capital and interest are due to be repaid in a single payment on 31 October 2028. 
Early repayment is permitted. No other fees are due under this facility.

Retirement benefit plans
Defined contribution plans
The Group operates a voluntary defined contribution retirement benefit plans for all qualifying employees of its UK companies. The 
assets of the plans are held separately from those of the Group in funds under the control of trustees.

The employees of the 4basebio S.L.U. are members of a state-managed retirement benefit plan operated by the government of 
Spain. The subsidiary is required to contribute a specified percentage of payroll costs to the retirement benefit plan to fund the 
benefits. The only obligation of the Group with respect to the retirement benefit plan is to make the specified contributions.

The total expense recognised in profit or loss of £259k (2022: £190k) represents contributions payable to these plans by the Group 
at rates specified in the rules of the plans. As at 31 December 2023, contributions of £21k (2022: £22k) due in respect of the current 
reporting period had not been paid over to the plans.

24.  Share based payments

The Group operates a share option scheme under which it grants and has granted share options in share capital to eligible 
employees of Group companies. These are accounted for as equity settled in the consolidated financial statements. The scheme 
was recognised as an Enterprise Management Incentive Scheme in the UK for tax purposes. Under the scheme both HMRC-
approved and unapproved options were issued to employees.

Notes to the financial statements 
(continued) 

On 18 December 2023, the Enterprise Management Incentive Scheme ceased to qualify as a tax efficient scheme for UK purposes, 
following transactions between shareholders in 4basebio PLC which meant that a single shareholding group exercised control 
over more than 50% of the voting shares in 4basebio PLC at that date and as reported on 1 February 2024. From that date, all share 
options awards by the Company will be treated as unapproved share options.

Share options awards made are as follows:

Of the 597,500 share options awarded on 25 January 2021, 92,475 vested on grant and 68,500 have lapsed. Of the remaining 
number, 244,600 options will vest equally on the first, second, third and fourth anniversary of award; 177,075 options will vest on 
certain share price targets being achieved after the first anniversary of the award; and 14,850 options will vest on a combination 
of time served and share price target. On 7 February 2023, the Company received a notice of exercise over 2,000 options.

26.  Additional information on financial instruments

Financial instruments
Management has determined that the carrying amounts in all measurement categories are reasonable approximations of the fair 
value of the respective financial instruments.

The financial liabilities of the 4basebio Group consist primarily of loans and trade payables. The main purpose of these financial 
liabilities is to finance the business activities of the 4basebio Group. The financial assets of the 4basebio Group essentially consist 
of trade receivables, cash and cash equivalents, and short-term deposits that result directly from its business activities.

The 4basebio Group is exposed to various financial risks in the course of its business activities. These include credit, liquidity and 
market risks. The management of these risks is the responsibility of the management of the 4basebio Group. The guidelines for 
managing the risks described below are reviewed and approved by management.

Credit risks
Credit risk is the risk that a business partner fails to meet its obligations under a financial instrument or customer contract and this 
leads to a financial loss. The 4basebio Group is exposed to credit risks in the course of its operating activities (in particular with 
regard to trade receivables) as well as risks in the course of its financing activities, including those from deposits with banks and 
financial institutions, foreign exchange transactions, and other financial instruments. On the basis of the positive experience to 
date, the 4basebio Group estimates the probability of occurrence to be low and the financial impact to be extremely low.

The credit risk from credit balances with banks and financial institutions is managed in accordance with Group guidelines s which 
requires a distribution of Group deposits across at least two banks.

Concentrations of risk arises when several counterparties engage in similar business activities or activities in the same geographic 
region or have economic characteristics that cause them to be equally affected in their ability to meet their contractual obligations 
in the event of changes in the economic or political situation or other conditions. The Group does not consider there to be undue 
risk concentration presently but regularly review this position.

Liquidity risk
The 4basebio Group monitors the risk of a possible liquidity bottleneck using regular budget and planning measures. The aim of 
the 4basebio Group is to ensure adequate liquidity in order to bridge short-term liquidity bottlenecks.

The following table shows the financial liabilities by maturity class based on the remaining time to maturity at the respective 
balance sheet date. A reconciliation of the amounts shown in the consolidated balance sheet is not possible, as the table shows 
non-discounted cash flows.

Market risk
Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate due to changes in market prices. 
Market risk includes currency and interest rate risks.

Currency risk is the risk that the fair value or future cash flows of a financial instrument are exposed to fluctuations due to changes 
in exchange rates. Exchange rate fluctuations have an impact on the presentation of assets and liabilities in the consolidated 
financial statements of 4basebio PLC prepared in GBP, insofar as assets and liabilities are denominated in currencies other than 
GBP. To control currency risk the 4basebio Group tries to carry out foreign cash flows in and out as promptly as possible and in a 
manner appropriate to that currency. Hedging transactions are not currently used. The assets and liabilities of the 4basebio Group 
reported in foreign currency largely relate to assets and liabilities denominated euros, which essentially result from the Group’s 
business activities. The 4basebio Group reviews currency requirements in the course of the year in order to reduce currency risk if 
needed.

The following table shows the effects on the result for the period before taxes and equity, which result from a five percent positive 
or negative development of the euro against the pound, the most important currency in which the 4basebio Group carries out 
transactions in addition to the pound:

Contingent liabilities and other financial obligations
4basebio SLU commenced legal proceedings in August 2022 in the Spanish Courts (Madrid and Valancia) against Tyris Tx, 
an entity wholly owned by Columbus Venture Partners, and other parties including partners of Columbus Venture Partners, 
concerning breach of confidentiality and entitlement of patent applications filed in the name of Tyris Tx. The Board does not 
consider the proceedings material to the Group’s commercial activities. The matter remains ongoing.

In May 2023, in what appears to be responsive proceedings, Tyris Tx commenced legal proceedings in the Spanish Courts (Madrid) 
against 4basebio SLU and 4basebio Discovery Limited, concerning breach of confidentiality and joint entitlement of certain patent 
applications in the names of 4basebio SLU and 4basebio Discovery Limited. Notice of the proceedings were received via linkedin 
messages. Since that time, court documents have been received in relation to 4basebio SLU; filings against 4basebio Discovery 
Limited have not yet been received. The Board and its legal representatives consider the claims received to be without merit. The 
matter remains ongoing.
