This was another strong period for the Company with 
continued growth in routes to market and higher 
future visibility SaaS revenues. The enlarged Group 
added a number of contracts from existing and new 
clients, benefiting from the Acquisitions made during 
2021, while the core product suite and strong market 
backdrop continued to underpin organic growth.  
New contracts won during the Period provide further 
validation of our market position while our software 
suite also provides a firm foundation from which the 
Group can continue to evolve. The long-term nature 
of our contracts, combined with our growing range of 
solutions, underpin the Board’s continued confidence 
in our ability to deliver future success. 
Notwithstanding wider concerns around the funding 
environment for drug discovery and development, we 
have seen no evidence of slowdown to date and our 
focus remains strong, and our focus remains on further 
broadening our portfolio of products and solutions that 
are attractive across the spectrum. This will continue 
to drive value while demonstrating the strength of our 
proposition.
Looking forward, we have a strong order book, and 
the Company is well placed to benefit from industry 
consolidation as well as continued loyalty from existing 
clients. We have rationalised the non-core elements of 
our portfolio and positioned ourselves to benefit from 
increased cross selling, to win and service customer 
contracts of all sizes and we look forward to building 
on the strong start to trading during the current year. 
The post period-end launch of the Centrus product 
suite further enhances our In Silico portfolio. This is 
an integral part of our long-term growth strategy and 
a significant area of planned investment for us over 
the next 12 months or so, reflecting broader market 
trends and growing demand for data insight leveraging 
computational 
and 
artificial 
intelligence 
based 
solutions. We will continue to focus on organic and, 
where appropriate, acquisitive growth opportunities 
as we build out high-margin revenue lines while 
delivering on our commitment to help our clients bring 
their life enhancing products to market faster.

This was a highly successful and strategically very 
important year for the business, with concentration on 
two main activities: to fully complete the integration 
of the three companies acquired in 2021; then to 
ensure that the resultant consolidated business was 
ideally positioned to commence the next phase of its 
development in 2023 and beyond.
Being the first full year to benefit from the Acquisitions, 
as expected, the results were positively impacted by 
the greater solution suite and routes to market now in 
place. This transformation of the business has not only 
increased the scalability and reach of our operations 
but has improved the Group’s ability to win larger 
contracts and attract opportunities that were not 
previously available.
Strategically, we aim to ensure that our solutions enable 
a shortening of the time taken for drugs to come to 
market and that we have an increasing number of 
touchpoints across the drug discovery and development 
lifecycle. 
F I N A N C I A L  P E R F O R M A N C E
All parts of the business benefited from the extension 
of our product range, which is becoming increasingly 
relevant to a wider cross section of customers. 
Furthermore, our ability to provide a growing number 
of solutions has enabled us to increase cross-selling 
as well as to add new customers that were previously 
outside of our reach.
During the Period we were able to pass on essential 
price increases to customers, which helped to mitigate 
the global inflationary pressures now being experienced 
by all businesses. Importantly, we also benefited from 
a further change in our revenue mix, with additional, 
higher margin and visibility SaaS revenue streams from 
existing and new clients.
The performance during the Period was aligned with 
management expectations post the completion of the 
Acquisitions with notable progress on a number of key 
metrics. In particular, increasing levels of SaaS-driven 
business and strong client retention rates continue to 
be cornerstone objectives.
•	
SaaS-based revenues grew 41% to £13.7m
•	
Total recurring revenues grew 43% to £34.5m
•	
Recurring revenue retention rate >98% 
•	
Total Group revenues increased 28% to £58.9m
•	
Adjusted EBITDA grew 32% to £10.9m
•	
Net cash generated from operations of £9.9m
L O O K I N G  F O R WA R D
Following a strategic review of our operations and 
opportunities the next phase of the development of 
the business will be based on the achievement and 
maintenance of a growing portfolio of  ‘world leading 
life science workflow and data solutions.’ These are 
grouped into three market focussed sectors.
STUDY MANAGEMENT
This sector has historically been the bedrock of the 
overall business. The products and services of the 
PDS acquisition have now been merged with the 
equivalent pre-existing Instem products and services. 
Consequently, we are now the clear market leader in the 
pre-clinical study management market. In  addition, 
we have now broadened our study management scope 
into the discovery phase of pharma R&D through the 
acquisition of The Edge.
CLINICAL TRIAL ACCELERATION
Solutions for clinical trial acceleration now provide 
an important opportunity for the Company. This was 
the principle market focus of the d-Wise business. We 
believe that, this, combined with the resources and 
market reach of Instem, will significantly leverage the 
potential in this area. 
We have already seen these benefits, with the Company, 
in September 2022,  winning its largest contract to date 
– worth $12m over five years.
IN SILICO/DATA SCIENCE
Artificial Intelligence (“AI”) is now one of the most 
exciting supporting technology areas in Pharma R&D, 
with its potential to generate significant improvements 
both in cost and timescale for new product development.
We separately announced today, 15 May 2023, that 
Instem is taking on responsibility for the management 
and further enhancement of the ‘ToxHub’ database 
and software platform. ToxHub was created by 
e-TRANSAFE (a consortium of global pharma 
companies, universities and technology companies, 
supported by EU grant funding) and has benefited 
from c.€41m investment to date.
ToxHub has become a component of recently launched 
solution suite Centrus. Maximising the potential for 
this new solution suite is strategically important and 
now a major focus of investment for the Company. 
Initially Centrus will provide an exciting axis for further 
growth of our existing In Silico solutions. However, it 
also sets the stall for the next stage of the Company’s 
development, which will include an increased focus on 
In Silico solutions.

Post-period end, we were delighted to welcome Mary 
Dolson as an Independent Non-Executive Director to 
the Board and Chair of the Audit Committee. Mary 
also joined as a member of the Remuneration and 
Nomination Committees. Mary is an expert advisor 
on regulatory, financial and accounting compliance 
issues, with extensive experience advising businesses 
in the pharmaceutical, biotech and life science sectors. 
She is an experienced specialist in taking companies 
through periods of change, from start-up to venture 
capital investments to public offerings. Upon Mary’s 
appointment, membership of the Company’s audit, 
remuneration and nominations committees was revised 
accordingly and the Company will continue to review 
membership of the various committees periodically in 
line with good governance practice.
Following Mary’s appointment David Sherwin, Non-
Executive Director, stepped down from the Board 
effective 31 January 2023. We would like to thank 
David for his support and guidance during nearly 50 
years at Instem.
I N  S U M M A R Y
Increasing levels of SaaS-driven business and strong 
client retention rates continue to the be cornerstone 
of our model. We will continue to build on the fact 
that our solutions remain critical in shortening the 
time taken for drugs to come to market, resulting in 
significant revenue growth for our blue-chip client 
base as they provide life changing new products for 
consumers world-wide.
We remain focused on organic revenue growth, margin 
improvement and accretive M&A and believe that the 
Company is extremely well placed to deliver further 
success. The performance during the Period is a strong 
reflection of the hard work across all parts of the 
business and the foundations we now have in place are 
expected to underpin material upside opportunities.

In 2022 we stated our clear intention to make material 
progress in integrating the data from our broad 
portfolio of market leading applications to deliver 
compelling new capabilities to the market and are 
delighted that post-period end we completed the 
transfer of eTRANSAFE’s ToxHub application to 
Instem, announced 15 May 2023. 
We are very excited about the potential of our expanded 
In Silico and Translation Science (“ISTS”) business unit, 
with our new Centrus™ solution suite incorporating:
•	
the acquired ToxHub technology
•	
our previous In Silico solutions
•	
the 
Clinical 
Trial 
Transparency 
solutions 
(previously within our Clinical Trial Acceleration 
business unit)
•	
the emerging opportunities to leverage the SEND 
information assets that are rapidly growing within 
pharmaceutical companies and contract research 
organisations around the world.
The Group’s focus remains on helping clients to radically 
reduce the cost and time of life sciences research and 
development, with In Silico alternatives to traditional 
client experimental processes representing a significant 
opportunity. Instem offers a range of solutions including 
predictive data analytics, simulation and modelling that 
provide clients with services from early drug discovery 
to late-stage clinical trials and, while already leveraging 
machine learning and AI technologies, there is much 
more we can do in these areas. 
With our increased focus on ISTS and a clear objective 
to optimize our clients R&D activities, we decided to 
dispose of our Regulatory Information Management 
“RIM” software business and this transaction completed 
post period end. Most of our RIM revenue since the 
acquisition of Samarind in 2016 has been in support of 
our clients’ post-marketing activities, as they launched 
their regulated products around the world. The 
opportunity that we envisaged to build on our strength 
in the medical devices niche was constrained by slower 
introduction of helpful regulatory changes and a 
medical devices market that was one of few that Instem 
targets that was negatively impacted by the Covid 
pandemic.  We believe that Ennov, a competitor in the 
RIM market and acquirer of our RIM business, will 
be a good home for a small team of dedicated former 
Instem staff and our RIM clients.  RIM represented less 
than 2% of total revenue in 2022.
RIM was part of our Regulatory Solutions business 
unit, alongside our much larger SEND related business. 
Having moved the responsibility for solutions that 
leverage large volumes of SEND studies for insight 
generation to ISTS, we have moved our SEND creation 
software and services into our Study Management 
business unit.  The clients in these areas and the 
workflow technology applications overlap significantly; 
together they provide greater opportunity to optimize 
efficiency and effectiveness for Instem and our clients.
As 2022 was the first year that incorporated full 
contributions from the Acquisitions made during 
2021, the results reflect the benefits of scale. With an 
enhanced solution suite servicing a growing number of 
touchpoints across the drug discovery and development 
lifecycle the Company won multiple new contracts and 
clients, which further enhanced SaaS revenue streams 
in particular.
Organic growth remained strong, with retention of 
recurring SaaS and Annual Support revenue once 
again ahead of the Company’s 98% key performance 
indicator and new business win rates confirming 
market leadership across its broad portfolio.
The Company has created a strong market position 
and substantial recurring revenues through helping 
our clients orchestrate and automate their study 
workflows. We are building on this firm foundation 
with an increasing focus on the higher growth areas 
in our portfolio, particularly the ISTS solutions that 
contribute across the entire R&D value chain from 
drug discovery to late-stage clinical trials and beyond. 
The industry recognises and is investing in advanced 
information technologies, such as AI and other data-
centric solutions, to both lower the cost and accelerate 
its drug development activities. Our ISTS technology, 
plus our deep understanding of the high volumes 
of complex data, collected through our workflow 
solutions over several decades in this industry, leave 
us well-positioned to drive forward both current and 
innovative new solutions.
M A R K E T  R E V I E W
The market backdrop continues to be favourable 
for the Group, with global population growth and 
life expectancy underpinning increased demand 
for successful innovation in life sciences. Increasing 
amounts of money are being invested in the biotech 
industry with the pharmaceuticals sector investing 
heavily in drug development, underpinning a strong 
pipeline for Instem.

In the pharmaceutical industry, which represents the 
largest proportion of Instem's revenue, we refer again 
to the Pharma R&D Annual Review, the 2023 version 
of which was released by Pharma Intelligence in April 
2023. This report shows that the industry grew strongly 
in the last 12 months with a 5.9% increase (2021: 8.2%) 
in the total number of drugs in the regulatory stages of 
global R&D, continuing a multi-year growth trend that 
shows no sign of abating. 
B U S I N E S S  P E R F O R M A N C E
STUDY MANAGEMENT
Performance here remained strong with revenue 
growth of 27%, compared with prior period growth 
of 35%, with both of these years benefiting from the 
Acquisitions in 2021 and reflecting the continuing 
growth in non-clinical research and development, with 
the number of drugs in this stage of development up 
4.9% (2021: 11%). In December 2022 the Company 
announced that it had entered into a contract extension 
worth c.$1.4m for over 900 additional users of the 
Provantis non-clinical study management platform 
with an existing leading publicly traded global CRO, 
highlighting the continued strength of its offering, 
client relationships and underlying market.  
The continual functional and technological evolution 
of the study management portfolio, which has been a 
mainstay of the business for many years, resulted in a 
number of new business wins. New product versions 
helped to maintain high levels of client retention and 
to support the ongoing transition of client deployments 
from on-premise to Instem’s SaaS solution.  With CRO 
consolidation a significant feature over the last few 
years, it is very encouraging that clients have invariably 
chosen to consolidate on Instem’s Provantis software 
when companies combining, through merger or 
acquisition, look to harmonize on a single solution, 
rather than retain competing study management 
products. In total, over 3,000 additional Provantis users 
were licensed in 2022.
IN SILICO AND TRANSLATIONAL SCIENCE 
Instem’s In Silico and Translational Science solutions 
enable organizations around the world to unlock critical 
biomedical intelligence contained in both public and 
proprietary data resources. Insights, generated from 
information produced across the R&D continuum, are 
used to support operational efficiencies and scientific 
advances throughout discovery, development and 
clinical practice.
In November 2022 the Company announced the 
release of the latest edition of its Leadscope Model 
Applier Computational Toxicology software solution, 
and significant improvements were also made during 
2022 to the KnowledgeScan Target Safety Assessment 
(TSA) platform.  Enhancements to these AI-enabled 
solutions, used for the assessment of chemical and 
biological mechanisms, support client demand for the 
combined benefits of both tools. Clients license the 
technology on a project or enterprise basis, or access 
it through Instem’s innovative, technology enabled 
services. Our ‘translational science’ capability has also 
been recently enhanced by the addition of products 
and services in clinical trial transparency, where clients 
are provided access to anonymised clinical trial data 
for regulatory submission and secondary use.  
A growing demand for reliable alternatives to 
traditional testing methods and particularly animal-
based studies in pharmaceutical development was a 
key factor in the Company adding the ToxHub suite of 
products post period end, which has been combined 
with our existing In Silico solutions as part of a new 
Centrus solution suite. Instem’s highly successful, 
long-term collaborations with the US Food & Drug 
Administration and our role orchestrating large scale 
industry initiatives, such as the In Silico Protocols 
project, create an excellent framework for ongoing 
collaboration with the eTRANSAFE Consortium 
members, who jointly specified and invested in the 
creation of ToxHub.  Centrus is expected to provide a 
spring board for accelerated ISTS revenue growth. 
REGULATORY SOLUTIONS
The Regulatory Solutions business unit comprised 
our SEND related software and technology enabled 
outsourced services, together with the Samarind 
RMS RIM software suite. In the highly competitive 
and challenging RIM market revenue declined 7% 
to c.£1.2m.  Conversely, our SEND business grew 
by 24% to £10.8m. Every drug company is required 
to submit non-clinical data in SEND format to the 
FDA (Food and Drug Administration), as part of the 
process for testing and getting approval for each new 
drug. The combination of increased numbers of drugs 
in development and SEND being extended to cover a 
broader range of study types, provided a solid platform 
for continued growth.
Having acquired PDS in September 2021, a competitor 
in the SEND software and services market, we were 
able to reallocate some of our industry experts to 
further investigate the opportunity to generate 
insight from our clients’ rapidly growing SEND 
information repositories. Post period end this work 
has now transitioned to our ISTS business unit and 
our technology and services for SEND creation have 
become part of Study Management.  As a consequence 
of these changes, Regulatory Solutions will no longer 
be reported independently.

CLINICAL TRIAL ACCELERATION SOLUTIONS 
Instem plays a key role in the acceleration of analysis 
and tabulation activities for late-stage clinical trials 
through its Statistical Computing Environment (SCE) 
consultancy and solutions. Instem is acknowledged 
as an authority in the design, implementation and 
optimisation of SCEs for the biggest clinical trials 
organisations to the new entrants and innovative 
biotechs advancing novel drugs. The Company’s 
solutions for late-stage clinical trials are designed to 
expand as customer needs grow and mature, providing 
essential scalability to these organisations. At the 
same time, Instem's SCE operating platforms provide 
sponsors and CROs an essential transformational 
bridge to cloud computing and the benefits of 
automation through AI and a wide array of open 
source and cloud-native technologies. SCE solutions 
from Instem open a gateway for organisations to access 
a new value space in computing technology that can be 
leveraged to advance data science and accelerate drug 
development programs.
Significant new business wins included the largest 
ever contract win for the Company – worth in excess 
of $12m over five years. This contract, provides over 
2,000 users worldwide at an existing CRO client, access 
to Instem’s new Aspire™ SCE software solution.  Aspire 
is a cloud-based SaaS solution targeting the largest 
pharma and CROs in the world and is another example 
of the company's SaaS growth strategy.  For this client, 
Aspire will be deployed on the Amazon Web Services 
cloud platform. With the focus on Aspire product sales 
and this key customer launch in Q4 2023, the volume 
of custom SCE development consulting projects has 
predictably dropped.  Aspire is anticipated to drive 
value for clients by accelerating SCE deployment 
timelines, reducing client modernization costs, while 
increasing recurring revenue and profitability of this 
business area.
Instem continued to provide productised statistical 
computing environments for small to mid-sized 
pharma companies and CROs with a steady growth in 
new clients and annual recurring revenue.

In addition to the various Board changes, we welcomed 
Mark Poggi to the Executive Team, joining as Executive 
Vice President Global Sales. Mark previously worked 
at CAS, a 1,200 employee subsidiary of the American 
Chemical Society, where he had an international team 
of around 85 people, over 3x the number he will initially 
lead at Instem, and responsibility for approximately 
~$190m in annual sales.  Additionally, Eve Leconte has 
been promoted to join the Executive Team as Chief 
People & Culture Officer.
Finally, John Alarcon was appointed Vice President 
of Strategic Partnerships and Vice President of US 
Finance. John joined Instem on a contract basis in 
2019 and led the buy-side due diligence, modelling, 
and integration efforts on the d-Wise acquisition, 
and supported on those of The Edge and PDS. John 
was also Interim Controller for Instem's Clinical Trial 
Acceleration business unit.

Mission and Vision Statement
Instem is a leading provider of IT solutions and services 
to the life science market with a mission to enable our 
customers to bring their life enhancing products to 
market faster. 
The Group’s mission and values align well with many of 
its customers to accelerate the discovery, development 
and delivery of their life enhancing products while 
complying with the relevant regulations. Instem’s 
suite of In Silico Solutions, in particular, helps reduce 
reliance on animal-based testing, with a strong 
industry, regulatory and societal desire to only use 
animals when alternative methods are not sufficient to 
assess potential risk.
As part of the acquisition integration process, in 2022 
the Group introduced a new vision and values for 
the new  One Instem. The Group’s vision is the future 
transformed for the benefit of everyone, with intelligent 
solutions empowering collaboration and life enhancing 
science. 
The Groups values which were introduced and 
reinforced during 2022 are:
•	
We are a community that thrives together
•	
We are bold, creative and curious 
•	
We are optimistic and love what we do
•	
We are inspired to deliver value
The Group’s vision and values have an important role in 
strategy development.  They help to shape the Group’s 
culture and to inform near and longer-term objectives. 
The global events over the last three years have 
highlighted more than ever the need for businesses to

operate in a socially responsible and environmentally 
sustainable way and to look after their staff by providing 
a safe operating environment.
As the Group expands, it has formalised its efforts 
in Environmental, Social and Governance (ESG), 
and has established an ESG Committee, represented 
by a diversity of colleagues from across the Group. 
The Committee has focused on key environmental 
aspects and, in light of the global pandemic, charitable 
activities. 
The Group has made good progress this year with its 
initial ESG targets and it is committed to developing 
a comprehensive ESG strategy over the forthcoming 
years, which will include key risks and opportunities 
for the Group.  
In 2021, the Group received its first external ESG rating 
from Gaïa Research which placed the Group above 
the national benchmarks for its sector and turnover 
category.
The Group received a credible B rating for its ESG 
evaluation score from Integrum ESG (“Integrum”) in 
October 2022. The Group’s score was determined by a 
combination of sustainability and governance scores as 
shown on the graph below.
ENVIRONMENT
Our Environmental impact
As a software and services solutions business, Instem’s 
activities do not involve any energy-intensive processes 
or generate significant waste. Nonetheless, Instem is 
committed to reducing its environmental impact and 
is developing an environmental strategy across the 
group, with the objective of ensuring that the Group 
minimises its impact on the environment as part of 
its business activities. This will also build on what the 
business has achieved so far, embracing new remote, 
flexible and collaborative ways of working across a 
simplified and reduced leased property portfolio, 
significantly reducing commuting impacts. During 
2022, two office leases expired in Guildford and Bury 
St Edmunds, UK and were not renewed. Further details 
are contained in Note 9.
Instem cares about the environment and fully supports, 
and is committed to, the principles of promoting 
good environmental practice and sustainability in the 
conduct of its activities. The Group wishes to minimise 
adverse effects on the environment. Our environmental 
strategy is implemented through the ESG Committee 
and 
regulatory 
requirements, 
considering 
the 
requirements of Streamlined Energy and Carbon 
Reporting (SECR) and the Task Force on Climate 
Related Financial Disclosures (TCFD).  We intend to 
improve the overall environmental performance of the 
Group, considering both our organisational profile and 
the local laws and regulations in which Instem offices 
are located. 
The COVID-19 pandemic brought with it a number of 
operational changes and development of  new Group-
wide strategies, including many that reduced our 
environmental impact. These included significantly 
reduced business travel.
The Group places great emphasis on its sustainability and ESG responsibilities and recognises the importance many 
of its investors and other stakeholders place on this aspect of our business.

The Group:
•	
complies with relevant environmental legislation
•	
reduces waste, where practicable, re-using and 
recycling consumables
•	
promotes paperless processes using electronic 
records
•	
minimise the consumption of energy and resources 
in the Group’s operations
•	
where possible, increase the procurement of 
environmentally friendly products.
Streamlined 
energy 
and 
carbon 
reporting 
requirements (SECR) statement
The Group is committed to monitoring and reducing 
its emissions year-on-year. 
In accordance with the Companies Act 2006 (Strategic 
Report and Directors’ Report) Regulations 2013, we 
report on greenhouse gas (“GHG”) emissions as part 
of the strategic report. The Group is also aware of its 
reporting obligations under The Companies (Directors’ 
Report) and Limited Liability Partnerships (Energy and 
Carbon Report) Regulations 2019, which implement 
the government’s policy on Streamlined Energy and 
Carbon Reporting (SECR).
As such, this year the Group is required to measure 
and report on energy and carbon data across its 
UK business, providing data to assess its overall 
environmental impact for Scope 1 and 2. 
In 2021 the Group reviewed the requirements of 
the Environmental Reporting guidelines. For each 
Company in the Group that qualifies as large their total 
energy consumption was below 40MWh and therefore 
the Group and Company was not required to prepare 
an Energy and Carbon Report. In 2022 the Group met 
the regulatory threshold and was therefore required to 
report.
Scope 1 covers direct emissions from owned or 
controlled sources. Scope 2 covers indirect emissions 
from the generation of purchased electricity, steam, 
heating and cooling consumed by the reporting 
company report for strengthening its energy and 
carbon reporting to meet these new requirements and 
to increase the transparency with which environmental 
impact is communicated to the Group’s stakeholders.
The Group has identified that the key intensity ratio, 
an expression of the quantity of emissions in relation 
to a quantifiable factor of business activity, which is in 
tonnes of CO2e per the floor area of the occupied office 
buildings and spaces. The carbon footprint during 
2022 was 55 tCO2e the total floor size was 17 thousand 
sq ft therefore the intensity ratio was 3.25 tCO2e per 
1000 sqft.
The table below contains the carbon emissions for the 
reporting period January to December 2022. The results 
are in compliance with UK SECR legislation covering 
energy use and associated greenhouse gas emissions 
relating to gas, electricity and transport, intensity ratios 
and energy efficiency actions.

The Group is committed to responsible carbon 
management and energy efficiency throughout the 
organisation. The group recognises that climate 
change is one of the most serious environmental 
challenges currently threatening the global community 
and understands the need to reduce greenhouse gas 
emissions.
To increase businesses energy efficiency the Group 
encourages the following policies
•	
Hybrid working for staff
•	
Reduced business travel
•	
A reduced property portfolio

Task Force for Climate- related Financial Disclosures 
(TCFD)
The TCFD was established by the Financial Stability 
Board to assist companies to assess climate-related 
financial risks. The TCFD has developed a series 
of recommendations on the disclosures, which 
organisations should include in their annual report, 
covering:
•	
Governance
•	
Strategy 
•	
Risk Management
•	
Metrics and targets
As part of our responsibility to manage our contribution 
to long-term climate change, we have included the 
recommendations from the TCFD as part of our new 
Environmental Strategy. This will assist in informing 
our stakeholders of our climate-related financial risks 
and how we manage them. 
Currently Instem is not required to report under the 
TFCD due to its size. However, we have engaged a 
third-party specialist who will be supporting us and 
publishing a matrix of results in the 2023 annual report. 
IT Equipment Waste Management
We already ensure that, as a Group, we are participating 
in a programme to recycle or re-purpose the highest 
amount possible of information technology equipment 
used internally. 
This year the Group received exemption for submitting 
its annual Waste Electrical and Electronic Equipment 
(WEEE) return because its equipment is designed only 
for research and development use and only available 
via business to business (B2B).
SOCIAL 
As a supplier to the healthcare industry, Instem’s 
technological innovations, software and services 
solutions have a positive impact on society world-wide.
Employment Practices 
People are at the heart of every stakeholder connection 
that Instem builds. Instem’s staff are a key component 
in the success of the business and in respect of this 
Instem has a dedicated People and Culture team that 
has implemented policies to support staff during their 
employment. 
As of 31 December 2022, Instem employed more than 
500 people globally. The business ensures its actions, 
working environment and policies prioritise employee 
wellbeing. This includes reward and recognition 
schemes, a flexible and considerate working approach 
and a growing diversity and inclusion programme. 
Instem believes that making positive changes within 
the organisation contributes to a positive ripple effect 
on society as a whole.
Ethical Practices and Human Rights
Instem places high emphasis on conducting its 
business with honesty and integrity and this forms 
part of our core values. The highest ethical standards 
are expected of management and employees alike and 
we continuously strive to create a corporate culture of 
honesty, integrity and trust. 
As a vendor of software and associated services, Instem 
operates in the highly regulated and ethically minded 
life sciences industry where there is not a prevalence of 
human rights issues. 
Internally, Instem addresses Anti-Corruption, Anti-
Bribery and Corporate Criminal Offences through 
HR policies and handbooks, ensuring staff understand 
their responsibilities in relation to ethical matters. 
Ethics and Code of Conduct training is also mandatory 
training for all staff. 
Our Human Resources Policy and Culture handbooks, 
together with our procurement practices, require 
Instem and third-party staff to be treated fairly and 
employed in accordance with all relevant laws and 
regulations for the locations in which they are based.
Ensuring that equal opportunities exist for all
The Group is fully committed to offering equal 
employment opportunities to all and its policies are 
designed to attract, retain and motivate staff, who can 
demonstrate that they have the necessary skills and 
capabilities, regardless of protected characteristics, or 
any other conditions not relevant to the performance 
of the job. The Group gives proper consideration to 
applications for employment when these are received 
from persons with disabilities, taking account of any 
reasonable adjustments that may be required for 
candidates with a disability. The Group’s policies are 
consistent with the requirements of the Universal 
Declaration on Human Rights and the spirit of the 
International Labour Organisation core labour 
standards.
Employee’s diversity 
Instem has a diverse global workforce with staff located 
across the UK, Europe, North America and Asia. As 
of 31 December 2022, 67% (2021: 66%) of employees 
were located outside of the UK.
The Group recognises the importance of gender 
diversity on its Board and within senior management. 
In January 2023 the Group was delighted to announce 
the appointment of Mary Dolson as an independent 
Non-Executive Director and chair of the Audit 
Committee and the appointment of Eve Leconte as 
Chief People and Culture officer to the Executive Team.

1 6
S T R AT E G I C  R E P O R T  ( C O N T I N U E D )
As the Group has less than 250 employees for each 
separate legal entity, it is not a reporting requirement to 
publish a gender pay gap report. However, the Group’s 
internal processes ensure that salary levels and salary 
increases are fair and comparable across its staff in all 
regions.
Engagement with the workforce
Annual staff surveys, incorporating both Gallup Q12 
and Great Place to Work® concepts, are undertaken 
by the People & Culture team to ensure our staff have 
an opportunity to express views on a wide range of 
employment and social issues. Regular staff reviews 
offer additional opportunities for such communications 
as well as to guide training and skills development. The 
results of the 2022 staff survey demonstrated that 92% 
(2021: 90%) of employees regard Instem as a great place 
to work which is also reflected in the Group’s attrition 
rate which is traditionally below the global average. 
During the year the Group expanded its range of 
employee engagement activities ensuring that the 
views and opinions of employees are heard and that its 
corporate values are upheld. Activities included: 
•	
quarterly company performance meetings for all 
staff and interactive forums to raise questions, 
topics of interest, provide feedback or listen to 
others
•	
acquisition integration forum meetings, which 
provide the opportunity to ask questions about the 
integration process
•	
trading updates and monthly management reports 
are shared with all staff
•	
highlighting mental health issues and raising 
awareness through mental health panel interviews 
with staff, resilience and stress management 
webinars 
and 
mental 
wellness 
workshops 
sustaining the “Wellbeing Wheel” to support staff 
mental health.
•	
introduction of the Instem Leadership Academy to 
help develop senior employees and improve their 
leadership skills.
Health and well-being for staff was promoted through 
employee communication channels and subsidised 
healthcare provision. The leadership team is encouraged 
to make discussions on wellbeing a regular feature of 
staff meetings. 
The Group made LinkedIn Learning available to 
every employee during 2022, providing free access to 
expert courses on subjects relating to work or personal 
development topics. 
An internal Kudos Award programme has been 
implemented across the whole Group where staff and 
managers are able to recognise exceptional individual 
staff and team performance.
Due to the impact of COVID-19, the homeworking 
policy which was introduced in 2021 along with a 
series of flexible working and holiday policies have 
supported the workforce through the difficulties of 
balancing childcare with work commitments. Regular 
staff surveys were also conducted and provided staff 
with an opportunity to provide feedback on any issues 
they were facing, in order for Instem to provide support 
as appropriate. 
Share scheme 
The Group is a strong believer that having an effective 
employee share ownership programme helps to align 
employee interests with shareholders and continues 
to provide an effective tool in attracting, retaining and 
motivating employees. In 2020, the Group launched 
an annual share option award scheme to all employees 
which are subject to continued employment at the 
point of options vesting after three years, with the first 
vesting point arising in April 2023.
Customer Issues
Instem has a clear strategic objective of meeting 
customer needs and expectations in the products and 
services that are supplied. The following processes help 
Instem achieve this aim: 
Software Development and Deployment
Instem has a comprehensive Software Development 
Lifecycle and robust testing processes that are 
overseen by Instem’s ISO9001:2015 certified Quality 
Management System.  
SaaS deployment of Instem solutions has enabled our 
customers to reduce their own IT infrastructure. 
Customer Support
Instem offers various support services to help our 
customers use Instem solutions efficiently and 
effectively. These include installation and technical 
configuration support, training, validation, consultancy 
and a global helpdesk. 
Instem also strives to meet customers’ needs and 
expectations by regularly enhancing our software 
through new functionality and software changes. 
Data Protection 
Instem has a Group wide data protection policy and 
document framework that sets out processes and the 
legal conditions that must be satisfied in relation to the 

1 7
obtaining, handling, processing, storage, transferring 
and destruction of personal information in relation to 
the laws and regulations of countries and regions in 
which Instem operates.  
Information Security and Business Continuity
At Instem, Information Security is embedded into all 
aspects of our business and we use a combination of 
technical, administrative and procedural controls to 
protect IT and information from being compromised. 
Instem’s security controls are managed according to 
our ISO 27001:2013 certified information security 
management system (ISMS) and implemented through 
a combination of people, technology and processes.
Instem's Business Continuity, Disaster Recovery 
and 
Information 
Security 
policies, 
procedures 
and assessments are designed to protect sensitive 
information and enable effective response to cyber or 
security threats. Our programs are designed to create 
a resilient operating environment with pre-planned 
response and recovery strategies in the event of business 
disruption. These strategies focus on safeguarding our 
people, assets, information and clients. Comprehensive 
cyber insurance is in place across the entire Instem 
organisation.
Instem maintains programs with frameworks and 
methodologies 
designed 
to 
effectively 
manage 
business continuity risk. Established emergency and 
crisis management activities and protocols have been 
interwoven into the Business Continuity Process. The 
Business Continuity Management Policy and Standards 
outline the mandates and minimum requirements that 
the business must follow to plan for and respond to 
disruptive events. Methods the Group has used are 
based on a proven, certifiable discipline (ISO 22301), 
although it should be noted that Instem is not certified 
to this standard.
Community Involvement and Development
With employees around the globe, we believe it is 
important to consider how our presence can benefit the 
local communities in which we operate.
This year, the Instem Charity Committee grew to 
seven members representing the UK, India, and US. 
The Instem Charitable Contribution Policy  was also 
published which defines how the Group will financially 
support charitable causes that align with the company 
mission, vision, and values.
We also consider common cultural threads that unite 
us as a global organisation, whilst meeting the needs of 
our employees in every region, elements of this include:
•	
Supporting a number of charities, including 
matched-funding of employee fundraising events 
such as MIND – Mental Health, East Cheshire 
Hospice, Cancer Research UK, Boston Marathon 
Jimmy Fund, Community Food Bank of New 
Jersey, Last Night a DJ Saved My Life / Adobe 
Junior School, Lichfield City of Sanctuary, Lullaby 
Trust, UAGTCA Kids Track and Field, Connah’s 
Quay High School / F1 in Schools competition.
•	
Partnering with the INSPIRE Safety Pharmacology 
Horizon 2020 project, which includes funding two 
PhD students in France. 
•	
Plans to extend the Group’s graduate recruitment 
scheme and establish a graduate apprenticeship 
centre of excellence.
•	
Nature photography and children’s nature drawing 
competitions which involved the sponsoring of an 
endangered animal at a zoo  or issuing vouchers for 
an environmentally friendly shop. 
•	
Sponsoring of a local bee colony near the Stone, 
UK office.
•	
Helping to make a positive difference in the lives 
of children in Tanzania through involvement with 
School in a Bag. Access to basic education is a 
human right  and is part of a route out of poverty.
GOVERNANCE
Organisational Governance
At Instem, the Executive management team, under the 
direction of the Board of Directors, strives to attend 
to the interests of all its stakeholders. Shareholders’ 
interests are also aligned with the long-term incentive 
plans provided to senior management, achievement of 
which is based on increasing the value of the company 
through an increasing Instem share price. Instem’s 
Board of Directors is committed to an appropriate 
composition of the Board and considers ways of 
achieving this by soliciting institutional shareholders’ 
views. In January 2023, an additional independent 
non-executive director was appointed. 
Instem is committed to having effective governance 
practices to support the pursuit of its corporate 
objectives, using appropriate management processes 
and systems to deliver the highest standards of ethical 
business conduct and corporate governance.
To further support these goals, a Governance, Risk 
management and Compliance (GRC) department has 
been established, with the aim of providing Instem with 
a collection of capabilities that allow the business to 
reliably manage governance, identify and manage risks 
and to provide an independent, internal quality audit 
function to ensure the business remains in compliance.
The Board of Directors is responsible for oversight 
of risks and ESG matters facing the Group (such as 
social, ethical, environmental, legal and regulatory 
compliance, business model resilience). These matters 
are routinely included at each Group board meeting.  

1 8
S T R AT E G I C  R E P O R T  ( C O N T I N U E D )
S E C T I O N  1 7 2  S TAT E M E N T
The Board recognises the importance of setting high 
standards of corporate governance and complying with 
all legal requirements. In particular, the Directors are 
required to act in accordance with a set of general duties 
as detailed within section 172 of the UK Companies 
Act 2006. These duties are summarised as follows; 
A Director of a Company must act in a way they 
consider, in good faith, would be most likely to 
promote the success of the Group for the benefit of its 
shareholders as a whole and, in doing so, have regard 
(amongst other matters) to: 
•	
The likely consequences of any decisions in the 
long-term 
•	
The interests of the Group’s employees 
•	
The need to foster the Group’s business relationships 
with suppliers, customers and others 
•	
The impact of the Group’s operations on the 
community and environment 
•	
The desirability of the Group to maintain a 
reputation for high standards of business conduct; 
and 
•	
The need to act fairly as between shareholders of 
the Company.
In accordance with section 172 of the Companies 
Act 2006 the Directors, collectively and individually, 
confirm that during the year ended 31 December 2022 
they acted in good faith and have upheld their ‘duty to 
promote the success of the Group’ to the benefit of its 
stakeholder groups.
Directors acknowledge the importance of forming 
and retaining a constructive relationship with all 
stakeholder groups. Effective engagement with 
stakeholders enables the Board to ensure stakeholder 
interests are considered when making decisions and 
is crucial for achieving the long-term success of the 
Group. 
Instem identifies seven key stakeholder groups 
associated with our business:
•	
Employees
•	
Clients
•	
Shareholders
•	
Partners
•	
Communities in which we operate
•	
Suppliers
•	
Environment
The Board recognises its duty to consider the needs 
and concerns of the Group’s key stakeholders during 
its discussions and decision-making. The Board has 
had regard to the importance of fostering relationships 
with its stakeholders as set out below and also detailed 
in the strategic report and corporate governance report 
of this report. More information on how the Directors 
have discharged their duties under section 172 of the 
Companies Act 2006 is also available in the strategic 
report on pages 18 to 20 and corporate governance 
report on pages 30 to 33.
Employees
We recognise that our employees are critical to the 
success of our business and we focus considerable 
attention on their positive engagement. This commences 
from their initial induction into the Group where new 
joiners are introduced to our Group Values and our 
Culture Handbook, which provide a framework for 
ensuring an alignment between Group and employee 
interests.  
The Board is fully committed to ensuring that the 
opinions of employees across all regions and business 
areas are regularly sought and factored into its decision-
making process. The Group has put in place extensive 
measures to engage with its employees and these are 
described in full in the ESG section within this report 
on pages 15 to 17, including practical examples of 
how these have been applied during the year. Through 
these engagement activities the Board is able to gather 
opinions and ideas from the wider workforce, identify 
any communication gaps or common areas of concern 
and address these through the Group’s activities.
There is frequent and open communication with 
employees, who are encouraged to share their 
opinions, informally and through regular surveys, both 
attributable and anonymously.  We have consistently 
used the Gallup Q12 engagement questions in our 
surveys to identify trends and our survey questions 
have been expanded over recent years to align with 
those used by the Great Place to Work® organisation. 
Employee-led, 
location 
specific 
Action 
Groups 
propose and implement changes to address employee 
identified opportunities for improvement. Proposals 
are considered by the Executive management team and 
actioned accordingly. 
Clients
We are fortunate to operate in an industry that has a 
highly collaborative culture with many businesses and 
scientific related societies and organisations.  Instem 

1 9
participates widely in these groups, networking closely 
with our clients and prospects, often taking a leadership 
role based on the considerable expertise of our staff and 
the broad experience we gain from working with many 
clients.  In addition, Instem organises multiple client 
engagement forums related to sectors of our market, 
specific products and common industry practices or 
regulation.  These Special Interest Groups provide 
input to strategy and operations, allowing us to ensure 
that our products and services meet the needs of the 
entire client (and prospect) community.
The Group is proactive in engaging directly with its 
clients to monitor and continually improve its service 
delivery and client satisfaction levels. We survey our 
clients annually and, more regularly, at the completion 
of each project and as we address each client support 
call.  These surveys also help us to plan and prioritise 
changes to our products, services and the broader 
engagement we have with clients across our business. 
In the event that any concerns are raised by clients, the 
Group ensures that these are addressed swiftly and that 
proactive engagement occurs to ensure ongoing high 
standards of service delivery.
Our client Strategic Advisory Board (“SAB”), 
comprises senior individuals with a broad industry 
perspective,  from a variety of client organisations. 
The SAB, which meets twice per year, is tasked with 
informing/validating Instem’s business, product and 
service strategy. It provides guidance to ensure Instem 
is successful in its mission to enable its clients to bring 
their life enhancing products to market faster.
The Group’s social media presence and activity 
has increased and improved during the year. At 
least daily or weekly updates are provided through 
the Company’s corporate social media channels 
(LinkedIn) and contain key updates.  Finally during 
the year, the Group’s marketing team has enhanced 
its customer communications and the way in which 
campaigns, product launches and solution migrations 
are 
communicated. 
Targeted 
and 
personalised 
communications are agreed between the Group’s 
marketing team and customers’ account and service 
delivery managers, to ensure that the right customers 
are informed and guided through any changes which 
may affect them.
Shareholders
With the professional guidance of our joint broker and 
nominated adviser, Singer Capital Markets, joint broker 
Stifel Nicolaus Europe Limited and our financial public 
relations advisers, Walbrook PR, the Group engages 
with shareholders through multiple channels, aiming 
to provide clear and informative updates.  Regulated 
News Service releases are provided regularly, both 
those required as an AIM-listed business and additional 
releases to keep shareholders, and the wider market, 
informed about interesting business developments.  We 
undertake multi-day institutional investor roadshows 
following the announcement of interim and full-year 
results, which provide an opportunity to also engage 
with a wider group of financial analysts and media. 
We typically organise, or attend, retail investor events, 
to ensure all shareholders have access to executive 
management on a regular basis.
As broker research is typically not available to all 
shareholders, we engage Progressive Equity Research 
to produce additional analyst research, which is freely 
available from the Instem Investor Centre website 
and through other investor channels. In addition, we 
subscribe for services from Proactive Investor who make 
a range of Instem video and audio interviews available 
for shareholder and wider investor consumption, 
aggregated with their own financial journalist coverage 
of Instem news.
Our annual general meeting (AGM) provides a 
formal avenue to receive shareholder feedback and an 
opportunity for us to consider the implications should 
resolutions not pass unanimously. We also take note of 
feedback from shareholder representative groups, who 
typically provide structured feedback ahead of annual 
general meetings. We ensure that shareholders are 
treated equally and fairly, regardless of the size of their 
shareholding or their status as a private or institutional 
shareholder. The Group provides clear and timely 
communications to all shareholders in their chosen 
communication medium, as well as via the Group’s 
website and via Regulatory News Service.
Additionally, the Group’s annual report and accounts 
is made available to all shareholders both online and 
in hard copy where requested. All presentations and 
announcements and other key shareholder information 
is available on the investor section of the Group’s 
website.
Partners
Instem has a number of strategic partners, with whom 
we actively engage to enhance our portfolio of world-
leading products and services.  Formal agreements 
govern these relationships and nominated Instem 
employees are responsible for maintaining a regular 
and open dialogue to ensure ongoing alignment 
of interests.  We frequently engage our partners in 
the wide variety of methods of client engagement 
described above to ensure they have a direct two-way 
line of communication with the end-users.
The Group actively encourages feedback from the 
Group’s partner firms on the quality of its services and 
products to support continuous improvement.

Communities
Instem has several offices around the world and 
many employees who work from home. We recognise 
our role as responsible employers and community 
representatives and encourage and support our staff in 
this regard, regularly providing matching funding for 
charitable activities.  There are regular staff organised 
fund raising events and other activities to support 
local causes that occur within our offices. Clearly this 
has been harder to accomplish during COVID-related 
office lockdown but we have done so wherever possible, 
for example we continued to pay our office cleaning 
staff despite offices being closed. 
Significantly, from a global community perspective, we 
also recognise the considerable role we play in helping 
our clients to provide their life enhancing products 
across the world.  We continually assess how we can 
optimise what we do to accelerate the availability of 
safe and effective drugs, vaccines and medical devices, 
as well as safer and more effective agrochemicals, that 
help to increase production to feed an ever-growing 
world population. 
The Board ensures that decisions made are responsible 
and ethical by taking into consideration the wider 
society external to the organisation. The Group is 
committed to contributing towards the community in 
which it operates.
Suppliers 
The Group engages closely with its suppliers and has 
internal procedures to ensure that appropriate due 
diligence is undertaken on these firms when they 
are engaged. Engagement with any new suppliers is 
subject to a formal process and requires final approval 
from Instem’s Governance, Risk management and 
Compliance (GRC) department.
Significant supplier contracts, of a recurring nature, 
require approval from the Board as a whole. These 
suppliers are chosen according to their ability to meet 
the Group’s own high standards and to demonstrate 
values that are consistent with those of the Group.
The Group is committed to building trusted 
partnerships with the Group’s suppliers, which are 
crucial to delivering many of our commitments.
The environment 
As a provider of software solutions, the Group’s 
operations have a relatively limited impact on the 
environment. However, the Board is committed to 
implementing measures that will result in incremental 
improvements to the Group’s environmental impact, 
such as minimising paper usage, considering the 
environmental credentials of its office spaces and by 
avoiding unnecessary travel and using video-based 
meeting facilities where appropriate.
We do encourage efficient energy usage and recycling 
in office.  Through investment in technology, staff in 
the right places and changing business practices, we are 
also striving to reduce the amount of air travel for staff 
between our international offices and to our globally 
dispersed client-base. For further details on this refer 
to page 13 to 15.
Finally, the Directors of the Group must act in a way 
they consider, in good faith, would be most likely to 
promote the success of the Group for the benefit of its 
shareholders as a whole and, in doing so, they have 
regard (amongst other matters) to the below: 
Maintaining a reputation for high standards of 
business conduct 
The Group is mindful that the continued growth and 
success of the Group is dependent upon maintaining 
high standards of business conduct, including:
•	
the ability to successfully compete within the 
market, to attract and retain clients, and to service 
these clients to a high standard; 
•	
the ability to attract and retain high quality 
employees; 
•	
the ability to attract investors and to meet their 
expectations of good governance and sound 
business conduct; and 
•	
the ability to meet the Group’s regulatory 
obligations, and to meet the expectations of 
relevant regulatory bodies.
This awareness underpins the formulation of the 
Group’s strategy and is evident throughout the Board’s 
decision making process. 
Ensuring that members of the Company are treated 
fairly 
The Group ensures that the Group’s shareholders are 
treated equally and fairly, regardless of the size of their 
shareholding or their status as a private or institutional 
shareholder. The Group provides clear and timely 
communications to all shareholders in their chosen 
communication medium, as well as via the Group’s 
website.

In addition, non-financial KPIs are periodically 
reviewed and assessed, including customer and staff 
satisfaction.
Instem’s revenue model consists of perpetual licence 
income with annual support and maintenance 
contracts, professional services, technology enabled 
outsourced services fees, SaaS subscriptions and 
consultancy services. 
Total revenues increased by 28% to £58.9m (2021: 
£46.0m) with constant currency revenue growth at 20%. 
This includes full year  revenue contributions from The 
Edge, d-Wise and PDS, which were acquired in March, 
April and September 2021 respectively. Recurring 
revenue, comprising Support & Maintenance contracts 
and SaaS subscriptions, increased during the year by 
43% to £34.5m (2021: £24.1m). Recurring revenue as a 
percentage of total revenue was 59% (2021: 52%). The 
recurring revenue as a percentage of total revenue has 
increased over the year primarily due to the change 
of d-Wise revenue mix moving towards recurring 
revenue instead of consulting services. Revenue from 
technology enabled outsourced services increased to 
£8.5m (2021: £6.4m).

* Recurring revenue includes Annual Support fees and SaaS subscription fees.
** Earnings before interest, tax, depreciation, amortisation, impairment of goodwill and non-recurring items.
Operating expenses excluding the non-recurring items 
increased by 27% in line with revenue reflecting the full 
year cost of the 2021 acquisitions, ongoing investment 
in operational teams and the increase in the rate of 
inflation, primarily in salaries. 
Adjusted earnings before interest, tax, depreciation, 
amortisation, impairment of goodwill and non-
recurring items (Adjusted EBITDA) increased by 32% 
to £10.9m (2021: £8.3m). For this measure of earnings, 
the margin as a percentage of revenue increased in 
the period to 18.4% from 17.9% in 2021, as the Group 
managed to increase the revenue in line with the salary 
inflation.
Non-recurring costs in the period were £1.2m (2021: 
£1.3m), consisting of £0.1m for legal expenses associated 
with an historical contract dispute and an additional 
provision of €1.2m (£1.0m) which relates to the full 
and final settlement of the dispute that originally arose 
in 2017. The historical contract dispute was settled in 
2022 for €1.5m (£1.3m). The non-recurring costs also 
include acquisition costs of £0.08m (2021: £1.0m) in 
respect of the earn out consideration of the Edge and 
d-Wise.  

2 2
S T R AT E G I C  R E P O R T  ( C O N T I N U E D )
Non-recurring income of €0.5m (£0.4m) relates to an 
insurance payment in relation to the historical contract 
dispute, refer to note 4 for non-recurring items.
The reported profit before tax for the year was £5.5m 
(2021: profit of £3.0m). The calculation of the adjusted 
profit before tax was changed in 2022 to include two 
additional components; the effect of foreign currency 
exchange and the unwinding of the financial liability 
included in finance income/(costs).  Those two 
components have been included to better reflect 
the normalised, ongoing operations of the Group. 
Adjusted profit before tax (i.e, adjusting for the effect 
of foreign currency exchange and the unwinding of the 
finance liability included in finance income/(costs), 
non-recurring items, impairment of goodwill and 
amortisation of intangibles arising on acquisitions) was 
£8.2m (2021: £5.9m, as restated).  
The total income tax charge in the year of £0.78m 
(2021: £1.3m) is an effective tax rate of 14.2% (2021: 
43.8%). The decrease in the tax charge is mainly due to 
the benefit from deferred tax of the UK corporation tax 
losses together with the US tax benefit available on the 
d-Wise acquisition. In the UK, the Group continues 
to receive additional tax relief on its research and 
development expenditure. 
The Group continues to maintain its investment in its 
product portfolio. Research and development costs 
incurred during the year were £7.5m (2021: £4.9m), of 
which £3.0m (2021: £2.2m) was capitalised. The Group 
has a development process in place and is committed to 
ensure its own technology continues to evolve to meet 
client needs.
The Group operates internationally and is exposed to 
foreign currency risk on transactions denominated in 
a currency other than the functional currency, and on 
the translation of the statement of financial position 
and statement of comprehensive income of foreign 
operations into Sterling.  The primary currency that 
exposed the Group to foreign currency risk in 2022 
were the US dollar transactions. In 2022, the revenue 
and Adjusted EBITDA growth on a constant currency 
basis, excluding the foreign exchange exposure was, 
20% and 19% respectively. The foreign exchange gain 
recorded during 2022 was £0.93m (2021: loss £0.04m), 
which is composed of realised and unrealised gains/
losses. 
Basic and diluted earnings per share calculated on an 
adjusted basis were 32.8p and 31.3p respectively (2021: 
21.5p basic and 20.4p diluted, as restated). The reported 
basic and diluted earnings per share were 20.8p and 
19.8p respectively (2021: 7.8p basic and 7.4p diluted). 
The Group cash generated from operations for the year 
was £9.9m (2021: £10.3m), a small reduction from 
prior year primarily due to working capital movement 
and the settlement of the historical contract dispute. 
The deferred and contingent consideration payments 
of £5.4m which related to the 2021 acquisitions were 
part of the net cash used in financing activities.  The 
net cash used in investing activities includes £3.0m 
(2021: £2.2m) from the capitalisation of software 
development. As a result, of the above the gross cash 
balance decreased from £15.0m at 31 December 2021 
to £14.0m at 31 December 2022. In addition to its 
organic cash reserves the Group has access to an HSBC 
debt facility of up to £20m, which was unutilised at the 
year end. 
The remaining financial obligations associated with The 
Edge and d-Wise acquisitions for 2023 are deferred and 
contingent consideration payments of £3.6m and £2.2m 
respectively in cash. The contingent consideration 
provision reflected management’s estimate that the 
entities would achieve their profitability targets and 
that the full amount of contingent consideration would 
be paid. This profitability target was confirmed in the 
period. 
Goodwill included in intangible assets reduced from 
31 December 2021 to 31 December 2022 due to an 
impairment loss of £0.11m on Samarind’s goodwill 
realised on disposal. Offsetting this there was an 
increase in d-Wise goodwill of £0.05m (US$0.06m) 
due to a change in the contingent consideration paid 
(note 12). 
The latest triennial actuarial valuation of the Group’s 
legacy defined benefit pension scheme as at 5 April 2020, 
was completed in July 2021. As part of the process, the 
Group has agreed a revised Schedule of Contributions 
with the Trustees of the Scheme, which are intended to 
clear the Scheme deficit by 30 September 2026 (note 
25).
On 31 December 2022, the IAS19 accounting pension 
deficit was unchanged at £2.0m (2021: £2.0m). The 
agreed Group cash contributions currently approximate 
to £0.6m per annum, payable through to September 
2026. The deficit at the 2022 year-end of £2.0m (2021: 
£2.0m) is represented by the fair value of assets of 
£8.4m (2021: £14.0m) and the present value of funded 
obligations of £10.4m (2021: £16.0m), after applying a 
discount rate of 4.8% (2021: 1.9%).
Movements in share capital and the share premium, 
merger and share based payment reserves reflect the 

2 3
exercise of share options during the period, the fair 
value of share options granted being charged to the 
Statement of Comprehensive Income and the issue of 
shares paid in lieu of cash as deferred consideration for 
d-Wise. The share capital of Instem at 31 December 
2022 was 22,704,308 ordinary shares of 10p each (note 
27).
In line with previous periods and given our policy 
of retaining cash within the business to capitalise on 
available growth opportunities, the Board has not 
recommended the payment of a dividend.

The calculation for the adjusted profit before tax was changed in 2022 compared with prior periods by including two 
additional components, the effect of foreign currency exchange and the unwinding of the finance liability included in 
finance income/(costs).  Those two components have been included as adjustments as they do not affect the ongoing 
operations of the Group. 
Adjusted profit before tax is after adjusting for the effect of foreign currency exchange and the unwinding of the 
finance liability included in finance income/(costs), non-recurring items, impairment of goofwill and amortisation 
of intangibles arising on acquisitions. The same adjustments are also made in determining adjusted earnings per 
share (“EPS”). The Board considers this adjusted measure of operating profit provides the best metric of assessing 
underlying performance.

An historical contractual licence dispute, which did 
not affect the ongoing operations of the Group, was 
settled in October 2022. 
As previously announced, the Group created a provision 
of £0.25m in 2017 and this was maintained in the 2021 
financial statements.  In 2022, the Group increased the 
provision equal to the amount that the legal dispute 
was settled of €1.48m (£1.3m), of which its insurer 
agreed to contribute €0.45m (£0.4m) resulting in a net 
payment due of approx. €1.0m (£0.9m). 
P R I N C I PA L  R I S K S  A N D 
U N C E R TA I N T I E S
The directors consider that the global pharmaceutical 
market is likely to continue to provide growth 
opportunities for the business. The combination of the 
high level of annual support renewals and low levels 
of customer attrition provides revenue visibility to 
underpin the Group strategy on product and market 
development. However, the Group’s products may be 
adversely affected if economic and market conditions 
are unfavourable and revenue may be affected by the 
impact of accounting or regulatory changes and/or 
funding restrictions in the industry.
The Group seeks to mitigate exposure to all forms of 
risk through a combination of regular performance 
review and a comprehensive insurance programme. 
Additionally, the Group has a significant proportion 
of recurring revenue (circa 59% of total) from annual 
support & maintenance and SaaS contracts from a well-
established global customer base.  Consequently, the 
Group ensures that it maintains a diversified portfolio 
in terms of customers, revenue mix, geography and 
markets.
Market and economic conditions
Market and economic conditions are recognised as 
principal risks in the current trading environment. 
The risk is mitigated by the monitoring of trading 
conditions and the constant search for ways to achieve 
efficiencies in the business without impacting levels 
of service. Additionally, the inflationary environment 
is being closely monitored. The Group is able to 
reduce the exposure in its client contracts with the 
vast majority allowing for inflationary increases to be 
applied to future fees.
The risk to the Group, as for most businesses, in regard 
to the COVID-19 pandemic appears to have peaked 
and we are not anticipating any material adverse impact 
on future trading. The Group has coped well with the 
COVID-19 pandemic, with staff working efficiently 
from home and the majority of the business relatively 
unaffected.
The Board considers the Group is relatively well 
protected against significant customer risk due to the 
Group’s diverse customer base. At the date of approval 
of these financial statements the macro-economic 
conditions remain unpredictable and as such remain 
a risk to the business which the Board continues to 
closely monitor.
Foreign currency risk
The Group operates internationally and is exposed to 
foreign currency risk on transactions denominated in 
a currency other than the functional currency and on 
the translation of the statement of financial position 
and statement of comprehensive income of foreign 
operations into Sterling.  The main currency giving 
rise to this risk is US dollars. The Group mitigates the 
foreign currency risk by having both cash inflows and 
outflows in the relevant foreign currency due to local 
revenue generation generally offset by a local cost base 
that creates a natural hedge. 
The Group generates material cash reserves through 
its Chinese subsidiary that are not readily available to 
the UK Group at short notice and, as such, the Group 
has to maintain sufficient working capital headroom 
in other territories to accommodate any delays in 
repatriating cash from China. In managing currency 
risks, the Group aims to reduce the impact of short-
term fluctuations on the Group’s cash inflows and 
outflows in a foreign currency. The Group continually 
assesses the most appropriate approach to managing 
its currency exposure in line with the overall goal of 
achieving predictable earnings growth. Over the longer 
term, changes in foreign exchange could have an impact 
on consolidation of foreign subsidiaries earnings.  A 
10% decrease in the average value of Sterling against 
the US dollar would have resulted in an increase in 
the Group’s profit before tax  by approximately £0.7m 
(2021: £0.6m).
Credit risk
Management aims to minimise the risk of credit losses.
The Group’s financial assets are bank balances and cash, 
and trade and other receivables, which represent the 
Group’s maximum exposure to credit risk in relation to 
financial assets.
The Group’s credit risk is primarily attributable to its 
trade receivables and the Group has policies in place 
to ensure that sales of products and services are made 
to customers with appropriate creditworthiness. No 
customer individually amounts to more than 10% of 
the Group revenue. At the 2022 year end the Group 
had a maximum credit risk exposure of £18.3m (2021: 
£14.9m).
The amounts presented in the statement of financial 
position are net of impairment provisions.

2 6
S T R AT E G I C  R E P O R T  ( C O N T I N U E D )
Note 16 sets out the impairment provision for credit 
losses on trade receivables and the ageing analysis of 
overdue trade receivables. There were no impairment 
losses recognised on other financial assets.
Liquidity risk
Liquidity risk is the risk that the Group will not be able 
to meet its financial commitments as they fall due. The 
Group’s objective is to ensure that adequate facilities 
are available through use of bank overdrafts and leases. 
The Group manages liquidity risk through regular 
cash flow forecasting and monitoring of cash flows, 
management review and regular review of working 
capital and costs. The Group regularly monitors its 
available headroom under its borrowing facilities, for 
further details refer to the going concern review.  
The Group signed a new financing arrangement in April 
2022, which consists of a committed facility of £10.0m 
with HSBC UK Bank plc, to support the Group's 
working capital needs and its acquisition strategy. The 
facility can also be extended up to £20.0m, if needed, 
subject to additional bank approval. The financial 
covenants have been considered in the cash forecast to 
ensure compliance. 
The Group had positive gross cash reserves of £14.0m 
at the end of the period, although £3.2m of the cash 
was held in bank accounts in China, where it has been 
traditionally harder to repatriate funds quickly. 
Cyber risk 
The Group handles significant amounts of data 
electronically and is therefore extremely aware of the 
risks that a cyber-attack could have on its business. 
It has robust standards in place for establishing and 
maintaining systems and processes to ensure that the 
highest standards of data protection are in place. This 
also applies to any third party who is handling data 
on behalf of the Group and its customers, such as 
third-party hosting providers. All staff are trained in 
identifying and responding to any perceived, or actual, 
cyber attacks. The Group maintains separate insurance 
cover to protect against the financial implications of 
any cyber threat.
Technology risk
Due to the evolving nature of technology platforms 
there is a risk of obsolescence. The Group’s future 
performance depends on software development, by 
introducing new and enhancing existing products to 
meet customer demand. If the Group does not respond 
effectively to technological changes, changes in client 
requirements and regulatory industry changes then its 
business may be negatively affected.
The Group monitors this risk and develops strategic 
development plans to ensure it remains compliant 
with technological advances. Additionally, the Group 
produces roadmaps for its key software products 
through its close relationships with clients and 
partners. In addition, the Group reviews forthcoming 
regulations to identify any need to change existing 
products and to identify opportunities for developing 
new products and services.
Acquisition and integration risk
With a strategy for growth, the Group ensures that 
acquisitions are handled appropriately from the 
outset. Acquiring differing businesses with differing 
technologies, people, competencies and processes 
creates risk to both customers and the products and 
services being acquired plus the Group’s existing 
operating model. Given the Group’s acquisition 
strategy this is considered an ongoing risk. The Group 
considers this risk split into three main areas with the 
following mitigations in place: 
•	
Acquisition target risk – the risk that the Group 
is unable to identify suitable acquisition targets. 
This risk is managed by a combination of 
internal resource dedicated to identifying targets 
complemented by use of external advisors. 
•	
Acquisition integration risk – the risk that 
completed acquisitions are not integrated into 
the underlying business in an efficient or effective 
way leading to potential loss of customers and 
employees from the acquired business. The 
risk is managed by detailed planning to ensure 
acquisitions are integrated effectively. 
•	
Post-acquisition performance risk – the risk that 
the acquired business may not perform as well 
as expected or synergies may not be delivered as 
planned. This has the potential to adversely impact 
both cashflow and profits post acquisition. 
Due diligence and integration planning help manage 
this risk including the use of experts throughout the 
acquisition process. The Group manages this risk 
by regular reviews of the operational structure and 
resource required to deliver to customers without 
degrading service. 
Recruitment and retention risk
As its people are the Group’s major asset, it is critical 
to ensure that it recruits the best staff possible and 

2 7
that these individuals are rewarded and developed 
appropriately. If the Group is unable to attract and 
retain suitably qualified personnel it is unlikely to meet 
its growth objectives and stakeholder expectations. 
The Group has a global People and Culture team that 
manages the process of ensuring the staff benefit and 
reward packages are incentivising for both recruitment 
and retention purposes. This includes benchmarking 
against peers and industry norms and considers staff 
feedback through regular performance review. During 
2020 the Group implemented an all-staff share scheme 
for the first time and has made annual awards thereafter. 
The options from the 2020 award were vested and 
became exercisable in April 2023.

financial statements.
O U T L O O K
This was another strong period for the Company with 
continued growth in routes to market and higher 
future visibility SaaS revenues. The enlarged Group 
added a number of contracts from existing and new 
clients, benefiting from the Acquisitions made during 
2021, while the core product suite and strong market 
backdrop continued to underpin organic growth.  
New contracts won during the Period provide further 
validation of our market position while our software 
suite also provides a firm foundation from which the 
Group can continue to evolve. The long-term nature of 
our relationships, combined with our growing range of 
solutions, underpin the Board’s continued confidence 
in our ability to deliver future success. 
Notwithstanding wider concerns around the funding 
environment for drug discovery and development, we 
have seen no evidence of slowdown to date and our 
focus remains on further broadening our portfolio 
of products and solutions that are attractive across 
the spectrum. This will continue to drive value while 
demonstrating the strength of our proposition. 
Looking forward, we have a strong order book, and 
the Company is well placed to benefit from industry 
consolidation as well as continued loyalty from existing 
clients. We have rationalised the non-core elements of 
our portfolio and positioned ourselves to benefit from 
increased cross selling, to win and service customer 
contracts of all sizes and we look forward to building 
on the strong start to trading during the current year. 
The post period-end launch of the Centrus product 
suite further enhances our In Silico portfolio. This is 
an integral part of our long-term growth strategy and 
a significant area of planned investment for us over 
the next 12 months or so, reflecting broader market 
trends and growing demand for data insight leveraging 
computational 
and 
artificial 
intelligence 
based 
solutions. We will continue to focus on organic and, 
where appropriate, acquisitive growth opportunities 
as we build out high-margin revenue lines while 
delivering on our commitment to help our clients bring 
their life enhancing products to market faster.

McGoun and M Dolson. 
The members of the Remuneration Committee are

Committee invites any person it thinks appropriate

at its meetings.  The Remuneration Committee meets 
at least once a year and any other time as required by 
either the Chairman of the Remuneration Committee 
or the Chief Financial Officer of the Group.
The Remuneration Committee:

rewarded for their individual contributions to 
the overall performance of the Group but also 
ensures that the Group avoids paying more than is 
necessary for this purpose;
b.	 considers the remuneration packages of the 
executive directors and any recommendations 
made by the Chief Executive Officer for changes to 
their remuneration packages, including in respect 
of bonuses (including associated performance 
criteria), other benefits, pension arrangements 
and other terms of their service contracts and any 
other matters relating to the remuneration of or 
terms of employment applicable to the executive 
directors that may be referred to the Remuneration 
Committee by the Board;
c.	 oversees and reviews all aspects of the Group’s 
share option schemes including the selection of 
eligible directors and other employees and the

independent committee of the Board; and
e.	 considers and makes recommendations to the 
Board about the public disclosure of information 
about the executive directors' remuneration 
packages and structures in addition to those 
required by law, or by the London Stock Exchange.
The Chairman of the Remuneration Committee 
reports formally to the Board on its proceedings 
after each meeting on all matters within its duties 
and responsibilities. The Remuneration Committee 
produces an annual report which is included in the 
Group’s annual report and accounts.
The Remuneration Committee is authorised to:
a.	 investigate any activity within its terms of reference;
b.	 seek any information it requires from any employee 
of the Group;
c.	 assess the remuneration paid by other UK listed 
companies of a similar size in any comparable 
industry sector and to assess whether changes to the 
executive directors’ remuneration is appropriate 
for the purpose of making their remuneration 
competitive or otherwise comparable with the 
remuneration paid by such companies; and
d.	 obtain, at the Group’s expense, outside legal or 
other independent professional advice, including 
independent remuneration consultants, when the 
Remuneration Committee reasonably believes it 
is necessary to do so and secure the attendance of 
such persons to meetings as it considers necessary 
and appropriate.

Committee considers this reasonably necessary 
and appropriate.	
I N T E R N A L  C O N T R O L S
The directors are responsible for establishing and 
maintaining the Group’s system of internal control 
and reviewing its effectiveness. The system of internal 
control is designed to manage rather than eliminate 
the risk of failure to achieve business objectives and 
can only provide reasonable but not absolute assurance 
against material misstatement or loss.
The Board and senior executives meet to review both the 
risks facing the business and the controls established to 
minimise those risks and their effectiveness in operation 
on an ongoing basis. The aim of these reviews is to 
provide reasonable assurance that material risks and 
problems are identified and appropriate action taken 
at an early stage. This approach is also adopted for any 
corporate acquisition, whereby controls, systems and 
processes of the target company are assessed during 
C O R P O R AT E  G O V E R N A N C E  S TAT E M E N T  ( C O N T I N U E D )

3 3
the due diligence phase and any areas of remediation 
are included in the planning of the Integration process 
post-acquisition.
During 2022, there was a high emphasis on 
understanding the existing control environment 
with the new acquisitions, identifying and reporting 
the issues to the local management, assisting on 
implementing the appropriate controls and integrating 
with existing internal controls. There is an ongoing 
integration process into our certified management 
systems for all acquisitions and the Group target is to 
apply the same internal controls for the Edge, d-Wise 
and PDS.

the payment of ad hoc awards to reflect exceptional 
performance. Cash bonuses amounting to £nil were

In accordance with the Companies Act 2006 (Strategic

report on GHG emissions as part of the strategic report 
on page 13 to 15. As such, this year the Group required 
to measures and reports on energy and carbon data 
across its UK business, providing data to assess its 
overall environmental impact for Scope 1 and 2. 
In 2021 the Group reviewed the requirements of 
the Environmental Reporting guidelines. For each 
Company in the Group that qualifies as large their total 
energy consumption was below 40MWh and therefore 
the Group and Company was not required to prepare 
an Energy and Carbon Report. In 2022 the Group met 
the regulatory threshold and was therefore required to 
report.

The directors are responsible for preparing the 
Strategic Report and Directors’ Report, the Directors’ 
Remuneration Report and the financial statements in 
accordance with applicable law and regulations.
Company law requires the directors to prepare financial 
statements for each financial year. Under that law the 
directors have to prepare the financial statements in 
accordance with UK-adopted international accounting 
standards. 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 and profit or loss of the company and Group 
for that period. In preparing these 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-adopted international 
accounting standards have been followed, subject 
to any material departures disclosed and explained 
in the financial statements;
•	
prepare the financial statements on the going 
concern basis unless it is inappropriate to presume 
that the company will continue in business.
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 and the Directors’ Remuneration 
report 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 confirm that: 
•	
so far as each director is aware, there is no relevant 
audit information of which the company’s auditor 
is unaware; and
•	
the directors have taken all the steps that they 
ought to have taken as directors in order to make 
themselves aware of any relevant audit information 
and to establish that the company’s auditor is aware 
of that information.
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.

We have audited the financial statements of Instem 
Plc (the ‘parent company’) and its subsidiaries 
(the ‘Group’) for the year ended  31 December 
2022 which comprise the Consolidated Statement 
of Comprehensive Income, the Consolidated and 
Parent Company Statements of Financial Position, 
the Consolidated and Parent Company Statements of 
Cash Flows and the Consolidated and Parent Company 
Statements of Changes in Equity, and notes to the 
financial statements, including significant accounting 
policies. The financial reporting framework that has 
been applied in their preparation is applicable law and 
UK-adopted international accounting standards and 
as regards the parent company financial statements, 
as applied in accordance with the provisions of the 
Companies Act 2006. 
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 2022 and of the Group’s 
profit for the year then ended;
•	
the Group financial statements have been properly 
prepared 
in 
accordance 
with 
UK-adopted 
international accounting standards;
•	
the parent company financial statements have 
been properly prepared in accordance with UK-
adopted international accounting standards and 
as applied in accordance with the provisions of the 
Companies Act 2006; and 
•	
the financial statements have been prepared 
in accordance with the requirements of the 
Companies Act 2006.
B A S I S  F O R  O P I N I O N
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 and parent company 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. 
C O N C L U S I O N S  R E L AT I N G  T O 
G O I N G  C O N C E R N 
In auditing the financial statements, we have concluded 
that the directors’ use of the going concern basis 
of accounting in the preparation of the financial 
statements is appropriate. Our evaluation of the 
directors’ assessment of the Group’s and parent 
company’s ability to continue to adopt the going 
concern basis of accounting included: 
•	
Obtaining management’s cash flow forecasts for 
the going concern period being twelve months 
from the date of signing the financial statements;
•	
Ensuring the mathematical accuracy of the cash 
flow forecasts;
•	
Comparing actual results for the year to forecasts 
to assess the forecasting ability and accuracy of 
management;
•	
Holding 
discussions 
with 
management 
to 
understand the cash flow forecasts including the 
key inputs used and sources of these inputs;
•	
Challenging management on the appropriateness 
of key assumptions and judgements used; 
•	
Identifying events subsequent to the year-end, 
which would be expected to impact the Group 
and Parent Company and hence the directors' 
assessment of going concern, and challenging 
management thereon to ensure that they had been 
factored into managements and the directors’ 
assessment; and 
•	
Considering the inherent risks to the business 
model and performing an analysis of how those 
risks might affect the financial resources or ability 
to continue operations over the going concern 
period.
Based on the work we have performed, we have not 
identified any material uncertainties relating to events 
or conditions that, individually or collectively, may cast 
significant doubt on the Group’s or parent company’s 
ability to continue as a going concern for a period of at 
least twelve months from when the financial statements 
are authorised for issue.
Our responsibilities and the responsibilities of the 
directors with respect to going concern are described 
in the relevant sections of this report.

Group financial statements
Parent Company financial statements
Materiality for the financial 
statements as a whole
£442,000
£302,000
Basis of materiality
c. 0.75% of turnover
c. 0.5% of net assets
Rationale Benchmark
We considered revenue to be the most relevant 
performance indicator of the Group as it is a 
significant driver of profit or loss for the year.
The Parent Company operates primarily as a holding 
company which holds the main debt facility for the Group 
and as such, we consider net assets as the key metric.
Rationale Percentage
The percentage applied to the benchmark has been selected to bring into scope all significant classes of transactions, 
account balances and disclosures relevant for the shareholders, and also to ensure that matters that would have a 
significant impact on the results were appropriately considered.
Performance materiality – 70%
£265,000
£181,000
In determining performance materiality, we considered the following factors:
•	
the number and quantum of identified misstatements identified by the predecessor auditors;
•	
routine transactions are not complex 
•	
the consistency in the level of judgement required in key accounting estimates;
•	
the stability in key management personnel; and 
•	
the level of centralisation in the Group’s financial reporting controls and processes.
We use performance materiality to reduce to an 
appropriately low level the probability that the aggregate 
of uncorrected and undetected misstatements exceeds 
overall materiality. Specifically, we use performance 
materiality in determining the scope of our audit and 
the nature and extent of our testing of account balances, 
classes of transactions and disclosures, for example in 
determining sample sizes.
For each significant component in the scope of 
our audit, we allocated a materiality based on the 
maximum aggregate component materiality. The 
range of materiality allocated across components was 
between £186,000 and £207,000. Group materiality has 
been used for material non-significant components.
We agreed with the Audit Committee that we would 
report to them misstatements identified during our 
audit above £22,100 as well as misstatements below 
those amounts that, in our view, warranted reporting 
for qualitative reasons.
O U R  A P P R O A C H  T O  T H E  A U D I T
In designing our audit, we determined materiality, as 
above, and assessed the risk of material misstatement in 
the financial statements. We looked at areas involving 
significant accounting estimates and judgement by 
the directors and considered future events that are 
inherently uncertain. We also addressed the risk of 
management override of internal controls, including 
evaluating whether there was evidence of bias by 
management that represented a risk of material 
misstatement due to fraud.
The Group had 27 subsidiaries as at the reporting date. 
A full scope audit was performed on the complete 
financial information of four components (including 
Instem Plc) which were assessed as material and 
significant. 15 components were considered material 
but not significant to which we performed audits of 
material balances using a materiality that is less than 
the materiality determined for the Group financial 
statements. For the remaining components not 
considered material, we performed a limited scope 
analytical review together with substantive testing, as 
appropriate, on Group audit risk areas applicable to 
those components based on their relative size, risks in 
the business and our knowledge of the entity appropriate 
to respond to the risk of material misstatement.
All component audit was performed in London, 
conducted by PKF Littlejohn LLP using a team with 
specific experience of auditing technology companies 
and publicly listed entities. 
K E Y  A U D I T  M AT T E R S 
Key audit matters are those matters that, in our 
professional judgment, 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) 
we identified, including those which had the greatest 
effect on: the overall audit strategy, the allocation of 
resources in the audit; and directing the efforts of the 
engagement team. These matters were addressed in 
the context of our audit of the financial statements as a 
whole, and in forming our opinion thereon, and we do 
not provide a separate opinion on these matters.

KEY AUDIT MATTER 
Revenue recognition 
Note 2 – 2022: £58.9 million (2021: £46 million)
As required by the auditing standards, we 
identified fraud risk related to the Group’s revenue 
recognition for all revenue streams including: 
•	
license and hardware
•	
SaaS and maintenance
•	
Professional, technology and consulting 
services 
Whilst there are limited judgements relating to 
license and SaaS and maintenance revenue, the 
external focus on the revenue increases the risk of 
fraudulent premature revenue recognition.
There is a risk in ascertaining the correct revenue 
to be recognised for the period with reference 
to IFRS 15 given management’s judgements in 
relation to the percentage of completion and 
in turn the revenue recognised. Inappropriate 
determination of when revenue recognition 
commences and terminates for the longer 
contracts may result in a material misstatement.
HOW OUR SCOPE ADDRESSED THIS MATTER
Substantive audit procedures performed in respect of revenue 
recognition are detailed below:
We obtained an understanding of the information system 
and design and implementation of controls relevant to 
each material income stream through a detailed systems 
description and walkthrough process;
License and Hardware (non-service revenue)
We assessed on a sample basis whether revenue has been 
recorded in the correct period, that performance obligations 
have been satisfied in the correct period by ensuring delivery 
was before year end and the correct transaction price has 
been used in the revenue recognition calculation by agreeing 
this to the contract/purchase order/sales invoice.
SaaS and Maintenance (service revenue)
We assessed on a sample basis whether revenue has been 
recorded in the correct period, performance obligations 
has been satisfied in the correct period and the appropriate 
transaction price has been used in the revenue recognition 
calculation by agreeing this to the contract term and price to 
the source documentation.
We challenged managements’ percentage of completion 
and recalculated the contact assets and deferred income as 
at the balance sheet date to confirm that revenue has been 
recognised in the correct accounting period.
Professional, Technology and Consulting services.
We assessed on a sample basis whether revenue has been 
recorded in the correct period, performance obligations has 
been satisfied in the correct period and the correct transaction 
price has been used in the revenue recognition calculation 
by agreeing this to the contract term and price to the source 
documentation.
We assessed and challenged the key terms of the purchase 
orders and contracts; as well as the percentage of completion 
to consider Group’s assessment of the revenue recognition 
consideration in line with the requirement of IFRS 15. We 
substantively tested these projects in order to assess, in detail, 
the terms and period of the service contract, time allocated 
to the project (accuracy of costs) and substantiation provided 
by the relevant Project Manager regarding the allocated 
percentage completion figure of the project resulting in 
revenue recognition.
We challenged management’s percentage of completion 
and recalculated the accrued income and deferred income 
as at balance sheet date to confirm that revenue has been 
recognised in the correct accounting period.
We critically assessed the adequacy of the financial statements 
disclosure in relation to revenue recognition and assessed 
that the accounting policies are in line with the requirements 
of IFRS 15.

KEY AUDIT MATTER 
Internally generated intangible assets - 
Development costs
Note 12 Software – 2022: £7.6 million (2021: £5.6 
million)
There are significant judgements involved 
in assessing whether expenses related to the 
Group’s development of new technology meets 
the capitalisation criteria of IAS38, in particular, 
the point at which technical and economic 
feasibility are demonstrated. During the year the 
Group capitalised costs related to projects where 
probable future economic benefits is achieved via 
customer renewals which judgemental. 
Where the capitalisation criteria as set out in 
IAS38 are met, the Group makes judgements in 
estimating the amount of time employees spent 
on development activities to determine the 
appropriate amount to capitalise.
We identified a risk of misstatement related 
to both the judgement as to whether the cost 
associated to a project can be capitalised and the 
estimation of employees’ capitalisation time. 
As such, the determination of the capitalised 
development costs is subject to a high degree of 
estimation uncertainty, with a potential range of 
reasonable outcomes greater than our materiality 
for the financial statements as a whole. 
HOW OUR SCOPE ADDRESSED THIS MATTER
Our work included but was not limited to:
For a sample of projects newly capitalised in the year, we 
inspected internal documentation and external assessment 
documentation from project managers to evaluate whether 
the technological feasibility was demonstrated at the 
reporting date.  We evaluated the Group’s assessment that 
economic feasibility had been demonstrated by assessing the 
revenue by products.
We reviewed employees’ contracts on a sample basis to 
evaluate whether the work of these individuals was directly 
linked to the development of the project. We considered 
the different employees involved in the development of the 
applications and the time spent developing the application.
We challenged the assumptions on the rate used to capitalise 
the internal employee costs based on the evidence provided, 
our knowledge and experience of the businesses and the 
industry they operate in.
We recalculated the capitalised costs using the applicable rate 
for the employees identified.
We considered the adequacy of the financial statements 
disclosure in respect of the significant estimates and 
judgements used in the determination of whether the 
capitalisation criteria have been met and the degree of 
estimation uncertainty in determining the amount to be 
capitalised.
Goodwill other acquired intangible assets 
impairment 
Note 12 Intangible assets – 2022: £58.3 million 
(2021: £58.3 million)
The estimated value in use/fair value less cost to 
sell for each of the identified CGU’s is subjective 
due to the inherent uncertainty and complexity 
involved in forecasting and discounting future 
cash flows of the CGU’s. There are also judgements 
involved in the Group’s forecasts of the costs to be 
excluded from the value in use estimates as well 
as other assumptions such as the discount rate, 
revenue retention rates, revenue multiple rates 
(for the fair value less cost to sell method).
As a result, the carrying value of goodwill and 
other intangibles is subject to a high degree of 
estimation uncertainty, with a potential range of 
reasonable outcome greater than our materiality 
for the financial statements as a whole. 
Our work included but was not limited to:
We assessed the appropriateness of methods used to calculate 
the recoverable amounts. 
We critically assessed the forecasted amounts in comparison 
to post period actuals to assess management’s accuracy with 
respect to forecasting. In addition, we critically assessed 
other assumptions used such as the discount rate, growth 
rate, overhead allocation based on our understanding of 
the business, knowledge attained throughout the audit and 
experience of the businesses and the industry they operate in.
With the assistance from our valuations specialist, critically 
assessed the discount rates and developed our own estimate 
of range of possible discount rates for each of the CGU, 
based on external market data and our understanding of 
the businesses, and compared this to the discount rates 
determined by the Group. 
We critically assessed management’s sensitivity analysis using 
market data and industry outlooks while summarising the 
quantitative impact on the year-end goodwill balance.
We assessed the appropriateness of the possible outcomes 
using the assumptions noted above, both individually and 
in aggregate, and assessed whether the disclosures reflect the 
risks inherent in the recoverable amounts of the identified 
CGUs.

As explained more fully in the directors’ responsibilities 
statement, the directors are responsible for the 
preparation of the Group and parent company 
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 Group and parent company financial 
statements, the directors are responsible for assessing 
the Group 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.

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:
•	
We obtained an understanding of the Group and 
Parent Company and the sector in which they 
operate to identify laws and regulations that could 
reasonably be expected to have a direct effect 
on the financial statements. We obtained our 
understanding in this regard through discussions 
with management, application of cumulative audit 
knowledge and experience of the sector.
•	
We determined the principal laws and regulations 
relevant to the Group and Parent Company in this 
regard to be those arising from the: 
•	
Companies Act 2006;
•	
UK-adopted international accounting 
standards;
•	
Quoted Companies Alliance Code;
•	
Local laws and regulations in the jurisdictions 
of the subsidiary entities;
•	
AIM Rules;
•	
Health and Safety Laws; and
•	
Anti-bribery and anti-money laundering 
regulations.
•	
We designed our audit procedures to ensure the 
audit team considered whether there were any 
indications of non-compliance by the Group and 
Parent Company with those laws and regulations. 
These procedures included, but were not limited 
to:
•	
Holding discussions with management and the 
audit committee and considering any known 
or suspected instances of non-compliance 
with laws and regulations or fraud; 
•	
Reviewing board meeting minutes;
•	
Reviewing Regulatory News Service (RNS) 
announcements;
•	
Reviewing legal and regulatory 
correspondence. 
•	
We also identified the risks of material misstatement 
of the financial statements due to fraud. We 
considered, in addition to the non-rebuttable 
presumption of a risk of fraud arising from 
management override of controls, that the potential 
for management bias was identified in relation to 
the revenue recognition, valuation of goodwill and 
investments, capitalised development costs as well 
as the valuation of the defined benefit obligations, 
including the key actuarial assumptions applied. 
We addressed this by challenging the assumptions 
and judgements made by management when 
auditing that significant accounting estimate and 
ensuring that there were adequate disclosures 
included in the respective notes including the 
disclosures within critical accounting estimates.
•	
As in all of our audits, we addressed the risk of fraud 
arising from management override of controls 
by performing audit procedures which included, 
but were not limited to: the testing of journals; 
reviewing accounting estimates for evidence of 
bias; and evaluating the business rationale of any 
significant transactions that are unusual or outside 
the normal course of business.
Because of the inherent limitations of an audit, there is 
a risk that we will not detect all irregularities, including 
those leading to a material misstatement in the financial 
statements or non-compliance with regulation. This 
risk increases the more that compliance with a law or 
regulation is removed from the events and transactions 
reflected in the financial statements, as we will be less 
likely to become aware of instances of non-compliance. 
The risk is also greater regarding irregularities 
occurring due to fraud rather than error, as fraud 
involves intentional concealment, forgery, collusion, 
omission or misrepresentation.
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. 
U S E  O F  O U R  R E P O R T
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.

The consolidated financial statements incorporate those 
of the parent company, Instem plc, and its subsidiary 
undertakings made up to 31 December 2022 and 31 
December 2021.
In preparing the consolidated financial statements, any 
intra-group balances, unrealised gains and losses or 
income and expenses arising from intra-group trading 
are eliminated.  Where accounting policies used in 
individual financial statements of a subsidiary company 
differ from Group policies, adjustments are made to 
bring these policies in line with Group policies.
Subsidiaries
Subsidiaries are entities in which the Group has rights to 
variable returns from its involvement with the investee 
and has the ability to affect those returns through its 
power over the investee. Subsidiaries are consolidated 
from the date on which control is transferred to the 
Group up until the date that control ceases.
All subsidiary companies within the Group have 
a financial year end date of 31 December, with the 
exception of Instem India Pvt Limited which has 
a financial year end date of 31 March, in line with 
Government of India regulations.
B U S I N E S S  C O M B I N AT I O N S
The Group applies the acquisition method in accounting 
for 
business 
combinations. 
The 
consideration 
transferred in a business combination is measured 
at fair value, which is calculated as the sum of the 
acquisition date fair values of the assets transferred 
by the Group, liabilities incurred by the Group to the 
former owners of the acquiree and the equity interests 
issued by the Group in exchange for control of the 
acquiree.  Acquisition related costs are recognised in 
profit or loss as incurred.
At the acquisition date, the identifiable assets acquired 
and the liabilities assumed are recognised at their fair 
value, except that deferred tax assets or liabilities are 
recognised and measured in accordance with IAS 12 
‘Income taxes’.
Consideration may consist of deferred consideration 
and contingent consideration. Deferred consideration 
is not based on any performance related conditions 
and is payable on an agreed future date. Contingent 
consideration is based on certain performance related 
conditions and payable on an agreed future date, if 
those conditions are met. 
Deferred consideration and contingent consideration 
is measured at their acquisition-date fair value 
and are taken into account in the determination of 
goodwill. Changes in the fair value of the contingent 
consideration that qualify as measurement period 
adjustments 
are 
adjusted 
retrospectively, 
with 
corresponding adjustments against goodwill.  The 
subsequent accounting for changes in the fair value 
of the contingent consideration that do not qualify as 
measurement period adjustments depends on how the 
contingent consideration is classified.  
Contingent consideration that is classified as a liability 
is re-measured at subsequent reporting dates with the 
corresponding gain or loss being recognised in the 
statement of comprehensive income.

Background 
The Directors have adopted the going concern basis 
in preparing these financial statements after careful 
assessment of identified principal risks and the possible 
adverse impact on financial performance. The Directors 
have assessed the financial position and liquidity at the 
end of the reporting period and for the forecast period 
up to 31 December 2024, including sensitivity analysis. 
The going concern period covers the 12 months from 
the date of signing the financial statements. The process 
and key judgments in coming to this conclusion are set 
out below. 
The Group’s activities, including the factors likely 
to affect its future development, performance and 
position are set out in the Chairman’s Statement and 
Strategic report. The financial position of the Group, its 
cash flows, liquidity position and borrowing facilities 
are described in the Financial Review.
Current trading and liquidity
The Group’s trading performance for the year ended 
31 December 2022 has been strong with Revenues 
of £58.9m and Adjusted EBITDA of £10.9m. For this 
measure of earnings, the margin as a percentage of 
revenue increased in the period to 18.4% compared 
with 17.9% in 2021. The Group managed to increase its 
revenue in line with the salary inflation through sales 
price increases.
The Group signed a new financing arrangement on 8 
April 2022, which consists of a committed facility of 
£10.0m with HSBC UK Bank plc to support the Group's 
working capital needs and its acquisition strategy, 
which can be extended up to £20.0m if needed, subject 
to further bank approval. The financial covenants have 
been considered in the forecast to ensure compliance. 
Instem undertook an oversubscribed equity fund raise 
in July 2020, raising £15.0m net of expenses. The fund 
raise placed the Group in a strong cash position which 
helped to accelerate the Group’s acquisition strategy 
with the acquisitions of the Edge, d-Wise and PDS. 
Even though the Group spent £17.2m initially funding 
the acquisition of The Edge, d-Wise and PDS in 2021 
followed by £5.4m in 2022 on deferred and contingent 
consideration, the Group has a strong cash position 
with £14.0m in the bank as of 31 December 2022.
The Group cash generated from operations for the year 
was £9.9m (2021: £10.3m), a small reduction from 
prior year primarily due to working capital movement 
and the settlement of an historical contract dispute. The 
dispute, which did not affect the ongoing operations of 
the Group, was settled in October 2022. As previously 
announced the Group had already created provision 
of £0.25m in 2017, which was maintained in the 2021 
financial statements.  In 2022, the Group increased the 
provision equal to the amount that the legal dispute was 
settled at €1.48m (£1.3m), towards which its insurer 
contributed €0.45m (£0.4m) resulting in a net payment 
due of approx. €1.0m (£0.9m). 
The Group acquired the earnings enhancing, cash 
generative businesses of the Edge, d-Wise, and PDS, 
which have been steadily integrated within the Group 
during 2022. 
The remaining financial obligations associated with The 
Edge and d-Wise acquisitions for 2023 are deferred and 
contingent consideration payments of £3.6m and £2.2m 
respectively in cash. The contingent consideration 
provision reflected management’s estimate that the 
entities would achieve their profitability targets and 
that the full amount of contingent consideration would 
be paid. This profitability target was confirmed as 
achieved in the period. 
Sensitivity Analysis
The Company has considered two scenarios which 
are also linked to the company’s risks when modelling 
the forecast results and cash flow. The sensitivity 
assessment includes the trading performance and cash 
flows of Centrus, our new solution suite incorporating 
the acquired ToxHub technology (note 33).
(a) Base Case Scenario
The Group's detailed forecasts and projections, taking 
account of potential risks and uncertainties in the 
business, market and liquidity through sensitivity 
analysis, show that the Group has adequate resources to 
enable it to continue in operation through the forecast 
period ending 31 December 2024 from the approval 
date of these Consolidated Financial Statements. 
Accordingly, the Group continues to adopt the going 
concern basis in preparing its Consolidated Financial 
Statements.
The uncertainty as to the future impact on the Group 
of the current inflation outlook has been considered as 
part of the sensitivity analysis and as part of Group's 
adoption of the going concern basis.   Thus far we have 
not observed any material impact on our overall existing 
business or in the level of new business opportunities 
that are being presented to us in the markets in which 
we operate. 
The Group has a significant proportion of recurring 
revenue (circa 59% of total) from annual support & 
maintenance and SaaS contracts from a well-established 
global customer base.  Revenue is supported by a largely 
fixed cost base comprising staff and offices. 

5 6
(b) Sensitised Scenario
Further stress testing has been carried out to ensure 
that the Group has sufficient cash resources to continue 
its operations until at least 31 December 2024. In 
preparing this analysis the following key risks were 
included -  a 35% loss of new business for the next 
twelve months and the risk effect of foreign exchange 
movements, particularly between the USD and GBP. 
Despite the negative impact of these sensitivities 
the model demonstrated that the Group remained 
profitable and cash generative over the going concern 
period to December 2024. 
In a worse case scenario where many of the identified 
risks occurred, the Group would take remedial action 
to counter the reduction in profit and cash through 
a cost cutting and fund-raising exercise that would 
include staff redundancies and general cost control 
measures. These further downside scenarios are 
considered unlikely. 
Conclusion and Going Concern Statement
After considering the uncertainties described above, 
the directors have a reasonable expectation that 
the  Group has adequate resources to continue in 
operational existence for the foreseeable future and as a 
minimum until 31 December 2024. For these reasons, 
they continue to adopt the going concern basis in 
preparing this annual report and accounts.
R E V E N U E  R E C O G N I T I O N
The Group generates revenue from the provision of 
software licences, annual support, SaaS subscriptions, 
subscription and support, professional services, 
technology 
enabled 
outsourced 
services 
and 
consultancy services. 
At contract inception, an assessment is completed to 
identify the performance obligations in each contract. 
Performance obligations in a contract are either goods 
or services that are distinct or part of a series of goods 
or services that are substantially the same and have the 
same pattern of transfer to the customer.  Promises 
that are not distinct are combined with other promised 
goods or services in the contract, until a performance 
obligation is satisfied.  	
At contract inception, the transaction price is 
determined, being the amount that the Group expects 
to receive for transferring the promised goods or 
services. The transaction price is allocated to the 
performance obligations in the contract based on 
their relative standalone selling prices. The Group 
has determined that the contractually stated price 
represents the standalone selling price for each 
performance obligation.  
Revenue is recognised when a performance obligation 
has been satisfied by transferring the promised product 
or service to the customer. 
Software licences
Licence revenue comprises the sale of software licences 
across the Group and the sale of compound credits 
by Leadscope and resale of complementary products. 
The revenue from software licences is recognised 
when the customer takes possession of the software 
which is usually when the licence key is provided to 
the customer. This is because the software is functional 
at the time the licence transfers to the customer and 
the Group is not required or expected to undertake 
activities that significantly affect the utility of the 
intellectual property by the customer. The revenue 
from compound credits is recognised at the point in 
time when the actual credits have been exercised, as the 
promises in these contracts are a single performance 
obligation.
Annual support 
Customers typically enter into a support contract for 
a period of twelve months. This contract provides the 
customer with access to technical support and software 
upgrades. Customers pay a fixed amount in exchange 
for the use of a cloud based statistical computing 
environment, along with access to maintenance and 
support. The promises in these contracts constitute a 
single performance obligation, which is satisfied over 
time as the customer consumes the benefits of the 
service consistently over the contract term.  Revenue 
in respect of the single performance obligation is 
recognised evenly over the contract term.
SaaS subscription and support
Customers typically enter into a SaaS contract for a 
period of twelve months and pay a fixed amount in 
exchange for the usage of software on a hosted server 
over a specified period of time along with access to 
maintenance and support. Initial SaaS contracts may 
also include some installation or customisation of the 
software and training for staff. The promises in this 
contract are considered to be a single performance 
obligation as the subscription and support are 
highly interdependent on one another given that the 
customers are required to take the full package of both 
A C C O U N T I N G  P O L I C I E S  ( C O N T I N U E D )

5 7
the software and support services i.e Instem would 
not be able to provide the support services without 
the provision of the software nor provide the software 
without the support services. 
The revenue is recognised over the period of the contract 
on a straight-line basis as the customer simultaneously 
receives and consumes the benefits of the software and 
services provided by the Group consistently over the 
contract term.
Subscription and support
Customers typically enter into a Subscription contract 
for an agreed period which could be more than twelve 
months and pay a fixed amount in exchange for the 
usage of software on a hosted server, computer based 
version or customer server version (in customer 
premises) over a specified period of time along with 
access to maintenance and support.  In some cases the 
initial subscription contracts may also include some 
installation services. 
The promises in these contracts are considered to be 
a single performance obligation as the subscription 
and support are highly interdependent on one another 
given that the customers are required to take the full 
package of both the software and support services 
i.e Instem would not be able to provide the support 
services without the provision of the software nor 
provide the software without the support services. 
The revenue is recognised over the period of the contract 
on a straight-line basis as the customer simultaneously 
receives and consumes the benefits of the software and 
services provided by the Group consistently over the 
contract term.
Professional services and technology enabled 
outsourced services
Customers typically enter into a service contract to 
provide distinct service work based on clear statements 
of work. Service work includes, but is not limited to, 
implementation services, training and outsourced 
services work relating to SEND, KnowledgeScan and 
Blur. The promises in this contract are considered to 
be a single performance obligation given the services 
are interdependent and the revenue is recognised on a 
percentage completion basis for fixed price contracts or 
as services are provided in respect of time and materials 
contracts. The Group has elected to take the practical 
expedient to apply this policy to its portfolio of distinct 
service contracts given the similar characteristics in 
these types of contracts.
Professional services include the revenue from funded 
development projects where customers typically 
enter into a service contract to accelerate product 
development.  Revenue for funded development work 
is recognised on a percentage completed basis. The 
percentage completed is determined with reference to 
time required to complete the development. 
Consultancy services
Customers typically enter into a service contract 
to provide distinct service work based on clear 
statements of work which include consulting services 
for clinical trial applications.  The consultancy services 
are contracted for on either a time and materials or 
fixed priced basis. Time and materials consultancy is 
recognised in the period in which it is performed. Fixed 
price work is recognised on a percentage completion 
basis of the remaining unbilled milestones. The 
percentage completed is determined with reference to 
time incurred to date and time required to complete 
the development or consultancy.
Bundled contracts
Software licences, professional services, cloud based 
statistical computing environment, and annual support are 
often bundled together in a contract.
Where the contract assessment identifies that the sale 
does not meet the criteria to be a distinct performance 
obligation, due to a lack of interdependence between 
performance obligations, promises that are not distinct 
are combined with other promised goods or services in 
the contract, until a performance obligation is satisfied. 
Revenue in respect of this bundled performance obligation 
is recognised over the period of the contracted obligation 
on a straight-line basis.
Amounts recoverable on contracts and deferred income
In most cases, customers are invoiced and payment is 
received in advance of revenue being recognised in the 
income statement. Amounts recoverable on contracts 
and deferred income is the difference between amounts 
invoiced to customers and revenue recognised under 
the policy described above. 
For 
professional 
services, 
technology 
enabled 
outsourced services and consultancy services the 
group will raise an invoice to the customer only if the 
performance obligation based on the agreement would 
be met.
Consequently, if the amount of revenue recognised 
exceeds the amounts invoiced the excess amount is 
included within amounts recoverable on contracts.
In comparison if customers are invoiced and payment is 
received in advance of revenue being recognised in the 
income statement then deferred income is recognised. 
Contract fulfilment asset
Contract fulfilment assets are amortised over the 
expected contract period on a systematic basis 
representing the pattern in which control of the 
associated service is transferred to the customer.  

5 8
Practical exemptions
The Group has taken advantage of the following 
practical exemptions:
•	
not to account for significant financing components 
where the time difference between receiving 
consideration and transferring control of goods (or 
services) to its customer is one year or less; 
•	
expense the incremental costs of obtaining a 
contract when the amortisation period of the asset 
otherwise recognised would have been one year or 
less; and
•	
to not disclose information relating to performance 
obligations for contracts that had an original 
expected duration of one year or less, or where 
the right to consideration from a customer is an 
amount that corresponds directly with the value of 
the completed performance obligations.

During the Period, the business was divided into 
four operating segments to better manage and report 
revenues; Study Management, Regulatory Solutions, 
In Silico Solutions and Clinical Trial Acceleration 
(CTA), see note 1.  The fourth segment was established 
following the acquisition of d-Wise in April 2021.
There has been an internal project to enhance the 
quality of management information following the 
implementation of a new finance system in 2019. During 
2020 this system enabled more centrally recorded costs 
to be allocated to the individual segments and that 
process was further developed in recent years.  
The operations of the Group are managed centrally 
with group-wide functions including sales, marketing, 
software 
development, 
information 
technology, 
customer support, people & culture and finance & 
administration. The CTA segment already bears the 
majority of its costs directly and as such reports a lower 
direct contribution margin to central overheads than 
the other three segments. However, during 2022 CTA 
has  benefited from synergies resulting in an overall 
improvement on the direct contribution margin.

Transactions in foreign currencies are translated 
at the foreign exchange rate ruling at the date of 
the transaction.  Monetary assets and liabilities 
denominated in foreign currencies at the reporting 
date are translated at the foreign exchange rate ruling 
at that date.  Foreign exchange differences arising 
on translation are recognised in profit or loss.  Non-
monetary assets and liabilities that are measured 
in terms of historical cost in a foreign currency are 
translated using the exchange rate at the date of the 
transaction.  Non-monetary assets and liabilities 
denominated in foreign currencies that are stated at 
fair value are translated at foreign exchange rates ruling 
at the date the fair value was determined.  
The assets and liabilities of foreign operations, 
including goodwill and fair value adjustments arising 
on consolidation, are translated at foreign exchange 
rates ruling at the reporting date.  The revenue and 
expenses of foreign operations are translated at an 
average rate for the year where this rate approximates 
to the foreign exchange rates ruling at the dates of the 
transactions, or otherwise at the exchange rate ruling at 
the date of each transaction.
Exchange differences arising from the translation of 
foreign operations are taken directly to the translation 
reserve.  They are released into profit or loss upon 
disposal of the foreign operation.

The Group issues equity-settled share-based payments 
to certain employees. Equity-settled share-based 
payments are measured at fair value at the date of grant 
by reference to the fair value of the equity instruments 
granted.  The fair value determined at the grant date 
of equity-settled share-based payments is expensed on 
a straight-line basis over the vesting period, based on 
the Group’s estimate of the number of instruments that 
will eventually vest with a corresponding adjustment to 
equity.  Fair values are measured by use of the Binomial, 
Monte Carlo or Black Scholes models.  The expected 
life used in the model has been adjusted, based on 
management’s best estimate, for the effect of non-
transferability, exercise restrictions, and behavioural 
considerations.
Non-vesting and market vesting conditions are taken 
into account when estimating the fair value of the 
option at grant date. Service and non-market vesting 
conditions are taken into account by adjusting the 
number of options expected to vest at each reporting 
date. Market vesting conditions are linked to the 
Group’s share price performance.  Non-market vesting 
conditions are linked to trading performance and 
service over defined time periods.
Cancelled or settled options are accounted for as an 
acceleration of vesting.  The unrecognised grant date 
fair value is recognised in profit or loss in the year 
that the options are cancelled or settled.  Where the 
terms of the options are modified and the modification 
increases the fair value or number of equity instruments 
granted, measured immediately before and after the 
modification, the incremental fair value is spread over 
the remaining vesting period.
Options over the Company’s shares granted to 
employees of the subsidiaries are recognised as a capital 
contribution in the subsidiaries and added to the cost 
of investment within Instem plc.
TA X AT I O N 
Taxation expense includes the amount of current 
income tax payable and the charge for the year in 
respect of deferred taxation.
The income tax payable is based on an estimation of the 
amount due on the taxable profit for the year.  Taxable 
profit is different from profit before tax as reported in 
the statement of comprehensive income, because it 
excludes items of income or expenditure which are not 
taxable or deductible in the year as a result of either 
the nature of the item or the fact that it is taxable or 
deductible in another year.  The Group’s liability for 
current tax is calculated by using tax rates that have 
been enacted or substantively enacted by the reporting 
date.
Income tax credits for research and development 
activities are recognised on a cash basis or when their 
receipt is reasonably certain.
Deferred tax is accounted for on the basis of temporary 
differences arising from the differences between the tax 
base and accounting base of assets and liabilities.
Deferred tax is recognised for all taxable temporary 
differences, except to the extent where it arises from the 
initial recognition of an asset or liability in a transaction 
that is not a business combination.  Deferred tax assets 
are recognised only to the extent that it is probable that 
future taxable profits will be available, against which 
temporary differences can be utilised. Deferred tax is 
recognised on income or expenses from subsidiaries 
that will be assessed, or allow for tax in future periods 
except where the Group is able to control the reversal of 
the timing difference and it is probable that the timing 
difference will not reverse in the foreseeable future.
Deferred tax is charged or credited to the statement of 
comprehensive income, except when it relates to items 
charged or credited directly to equity, in which case it is 
dealt with within equity.  It is calculated at the tax rates 
that are expected to apply to the period when the asset 
is realised or the liability is settled.

Intangible assets purchased separately from a business 
are capitalised at their cost. 
Intellectual Property, Customer Relationships, 
Brand Names and Patents
The Group makes an assessment of the fair value 
of intangible assets arising on acquisitions. These 
include Intellectual Property, Customer Relationships, 
Brand Names and Patents.  An intangible asset will 
be recognised as long as the asset is identifiable and 
its fair value can be measured reliably.  An intangible 
asset is identifiable if it is separable or if it was obtained 
through contractual or legal rights.  Amortisation is 
provided on the fair value of the asset and is calculated 
on a straight-line basis over its useful life.  The useful 
life for Intellectual Property, Customer Relationships, 
Brand Names and Patents is between five and fifteen 
years.  Amortisation is recognised within the statement 
A C C O U N T I N G  P O L I C I E S  ( C O N T I N U E D )

6 1
of comprehensive income.  All intangible assets except 
Goodwill are amortised and are tested for impairment 
whenever events or changes in circumstances indicate 
the carrying amount may not be recoverable.
Goodwill
Goodwill on acquisitions, being the excess of the fair 
value of the cost of acquisition over the Group’s interest 
in the fair value of the identifiable assets and liabilities 
acquired, is capitalised and tested for impairment 
on an annual basis.  Goodwill is carried at cost less 
accumulated impairment losses.
Any impairment is recognised immediately in profit or 
loss and is not subsequently reversed.  For the purpose 
of impairment testing goodwill is allocated to cash 
generating units of Instem plc, which represent the 
smallest identifiable group of assets that generates cash 
inflows that are largely independent of the cash inflows 
from other assets or groups of assets.
Computer Software
Computer software is carried at cost less accumulated 
amortisation and any impairment loss.  Externally 
acquired computer software and software licences are 
capitalised and amortised on a straight-line basis over 
their useful economic lives of three years.  Costs relating 
to development of computer software for internal use 
are capitalised once the recognition criteria of IAS 
38 “Intangible Assets” are met.  When the software is 
available for its use, these costs are amortised over the 
estimated useful life of the software.
Internally generated intangible assets 
Expenditure on research activities is recognised in the 
statement of comprehensive income as incurred.
Expenditure arising from the Group’s development of 
software for sale to third parties is recognised only if all 
of the following conditions are met:
•	
an asset is created that can be identified;
•	
it is probable that the asset created will generate 
future economic benefits; 
•	
the development cost of the asset can be measured 
reliably;
•	
the Group has the intention to complete the asset 
and the ability and intention to use or sell it;
•	
the product or process is technically and 
commercially feasible; and 
•	
sufficient resources are available to complete the 
development and to either sell or use the asset.
Capitalised development costs are those which are 
directly attributable to the development activity and 
include employee costs, overheads and direct third 
party costs.
Where the criteria have not been met, development 
expenditure is recognised in profit or loss in the period 
in which it is incurred. 
Internally-generated intangible assets are amortised, 
once the product is available for use, on a straight-line 
basis over their useful lives (five to eight years) and are 
tested for impairment whenever events or changes in 
circumstances indicate the carrying amount may not 
be recoverable. Any capitalised internally developed 
software that is not yet complete is not amortised but is 
subject to impairment testing.
Gains or losses arising from derecognition of an 
intangible asset are measured as the difference between 
the net disposal proceeds and the carrying amount of 
the asset and are recognised in profit or loss when the 
asset is derecognised.
P R O P E R T Y,  P L A N T  &  E Q U I P M E N T 
Property, plant and equipment are stated in the 
statement of financial position at cost less accumulated 
depreciation and provision for impairments.
Depreciation is provided on all assets so as to write off 
the cost less estimated residual value on a straight-line 
basis as follows:
•	
Short leasehold property - Over term of lease	
•	
IT hardware and software - 25% - 33% per annum
The expected useful lives and residual values of 
property, plant and equipment are reviewed on an 
annual basis and, if necessary, changes in useful lives 
are accounted for prospectively.  
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 the statement of comprehensive 
income.
L E A S I N G
The Group as a lessee
The Group makes use of leasing arrangements 
principally for the provision of office space and IT 
equipment. The Group does not enter into sale and 
leaseback arrangements. All the leases are negotiated 
on an individual basis and contain a wide variety 
of different terms and conditions such as purchase 
options and escalation clauses.
The Group assesses whether a contract is a lease 
or contains a lease at inception of the contract. A 
lease conveys the right to direct the use and obtain 
substantially all of the economic benefits of an identified 
asset for a period of time in exchange for consideration.
Some lease contracts contain both lease and non-lease 
components. These non-lease components are usually 

6 2
associated with facilities management services at 
offices. The Group has elected to not separate its leases 
for offices into lease and non-lease components and 
instead accounts for these contracts as a single lease 
component.
Measurement and recognition of leases as a lessee
All leases are accounted for by recognising a right of 
use asset and a lease liability except for: 
•	
Leases of low value assets; and 
•	
Leases with a term of 12 months or less. 
Lease liabilities are measured at the present value of 
the contractual payments due to the lessor over the 
lease term, discounted using the Group’s incremental 
borrowing rate because as the lease contracts are 
negotiated with third parties it is not possible to 
determine the interest rate that is implicit in the lease. 
The incremental borrowing rate is the estimated rate 
that the Group could have to pay to borrow the same 
amount over a similar term and with similar security to 
obtain an asset of equivalent value. This rate is adjusted 
should the lessee entity have a different risk profile to 
that of the Group. 
Lease payments included in the measurement of the 
lease liability are made up of fixed payments (including 
in substance fixed) and variable payments based on an 
index or rate.
In such cases, the initial measurement of the lease 
liability assumes the variable element will remain 
unchanged throughout the lease term. Other variable 
lease payments are expensed in the period to which 
they relate.
On initial recognition, the carrying value of the lease 
liability also includes: 
•	
amounts expected to be payable under any residual 
value guarantee; 
•	
the exercise price of any purchase option granted 
in favour of the Group if it is reasonably certain to 
assess that option; 
•	
any penalties payable for terminating the lease, if 
the term of the lease has been estimated on the 
basis of termination option being exercised. 
Right of use assets are initially measured at the amount 
of the lease liability, reduced for any lease incentives 
received, and increased for: 
•	
lease payments made at or before commencement 
of the lease; 
•	
initial direct costs incurred; and 
•	
the amount of any provision recognised where 
the Group is contractually required to dismantle, 
remove or restore the leased asset (typically 
leasehold dilapidations).
Subsequent to initial measurement lease liabilities 
increase as a result of interest charged at a constant rate 
on the balance outstanding and are reduced for lease 
payments made. Right of use assets are amortised on 
a straight-line basis over the remaining term of the 
lease or over the remaining economic life of the asset if, 
rarely, this is judged to be shorter than the lease term. 
When the Group revises its estimate of the term of 
any lease (because, for example, it re-assesses the 
probability of a lessee extension or termination option 
being exercised), it adjusts the carrying amount of 
the lease liability to reflect the payments to make over 
the revised term, which are discounted at the revised 
discount rate at the date of re-assessment or effective 
date of a lease modification is used. The carrying value 
of lease liabilities is similarly revised when the variable 
element of future lease payments dependent on a rate 
or index is revised. The lease liability is remeasured only 
when the adjustment to lease payments takes effect and 
the revised contractual payments for the remainder 
of the lease term are discounted using an unchanged 
discount rate. In both cases an equivalent adjustment 
is made to the carrying value of the right of use asset, 
with the revised carrying amount being amortised over 
the remaining (revised) lease term. 
When the Group renegotiates the contractual terms of 
a lease with the lessor, the accounting depends on the 
nature of the modification: 
•	
if the renegotiation results in one or more additional 
assets being leased for an amount commensurate 
with the standalone price for the additional rights-
of-use obtained, the modification is accounted for 
as a separate lease in accordance with the above 
policy 
•	
in all other cases where the renegotiation results in 
an increase in the scope of the lease (whether that 
is an extension to the lease term, or one or more 
additional assets being leased), the lease liability is 
remeasured using the discount rate applicable on 
the modification date, with the right of use asset 
being adjusted by the same amount 
A C C O U N T I N G  P O L I C I E S  ( C O N T I N U E D )

6 3
•	
if the renegotiation results in a decrease in the 
scope of the lease, both the carrying amount of 
the lease liability and right of use asset are reduced 
by the same proportion to reflect the partial of 
full termination of the lease with any difference 
recognised in profit or loss.  The lease liability is 
then further adjusted to ensure its carrying amount 
reflects the amount of the renegotiated payments 
over the renegotiated term, with the modified lease 
payments discounted at the rate applicable on the 
modification date. The right of use asset is adjusted 
by the same amount. 
In determining the lease term, the Group assesses 
whether it is reasonably certain to exercise, or not 
to exercise, options to extend or terminate a lease. 
This assessment is made at the start of the lease and 
is re-assessed if significant events or changes in 
circumstances occur that are within the lessee’s control.
The Group has elected to account for short-term leases 
assets using practical expedients. Instead of recognising 
a right-of-use asset and lease liability, the payments in 
relation to these are recognised as an expense in profit 
or loss on a straight-line basis over the lease term.
The Group applies judgement in determining whether 
individual leases can be accounted for as a portfolio. 
The judgements include an assessment of whether the 
leases share similar characteristics and whether the 
financial statements would be materially different if 
each lease was accounted for individually. The Group 
leases a number of properties in the jurisdictions 
from which it operates. In these jurisdictions the 
periodic rent is fixed over the lease term, with 
inflationary increases incorporated into the fixed 
payments stipulated in the lease agreements. Where 
rental agreements include market rate escalations, 
the lease liability is re-measured when the change in 
cash payments takes effect. The Group also leases one 
vehicle. Leases of vehicle comprise only fixed payments 
over the lease terms.
The Group as a lessor
The Group acts as a lessor in relation to a sublease of 
part of one of the properties it leases. As a lessor the 
Group classifies its leases as either operating or finance 
leases. A lease is classified as a finance lease if it transfers 
substantially all the risks and rewards incidental to 
ownership of the underlying asset and classified as an 
operating lease if it does not.
As the lease term is for the major part of the economic 
life of the underlying right of use asset this has been 
treated as a finance lease. The right of use asset has 
therefore been derecognised and a net investment 
in the lease recognised instead. Interest income is 
recognised on the lease receivable.

The carrying value of property, plant and equipment 
and intangible assets (excluding goodwill) is reviewed 
for impairment whenever events or changes in 
circumstances indicate the carrying value may not be 
recoverable.  
At each reporting date the Group reviews the carrying 
value 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 in order to determine the extent of 
the impairment loss.
Where the asset does not generate cash flows that are 
independent from other assets the Group estimates 
the recoverable amount of the cash generating unit 
(‘CGU’) to which the asset belongs.  A CGU is the 
smallest identifiable group of assets that generates cash 
inflows that are largely independent of the cash inflows 
from other assets or groups of assets.
Recoverable amount is the higher of fair value less 
costs to sell 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 as an expense 
immediately.
Where an impairment loss subsequently reverses, 
the carrying amount of the asset is increased to the 
revised estimate of its recoverable amount, but so that 
the increased carrying amount does not exceed the 
carrying amount that would have been determined 
had no impairment loss been recognised for the asset 
in prior years.  A reversal of an impairment loss is 
recognised in profit or loss immediately.
I M PA I R M E N T  T E S T I N G  O F 
G O O D W I L L
For impairment assessment purposes, assets are 
grouped at the lowest levels for which there are largely 
independent cash inflows (CGUs).
CGUs to which goodwill has been allocated are tested 
for impairment at least annually.
An impairment loss is recognised for the amount by 
which a CGU’s carrying amount exceeds its recoverable 
amount, which is the higher of fair value less costs of 
disposal and value-in-use. 

6 4
To determine the value-in-use, management estimates 
expected future cash flows from each CGU and 
determines a suitable discount rate (WACC) in order 
to calculate the present value of those cash flows.
The data used for impairment testing procedures are 
directly linked to the Group’s latest approved budget, 
adjusted as necessary to exclude the effects of future 
reorganisations and asset enhancements. The budgeted 
unallocated departmental costs are assigned to each 
CGU using an approach agreed by the board. 
To determine the fair value less cost to sell, management 
estimates the cash flow that will be received by selling 
the CGU at the end of the reporting period. They 
then assess the characteristics of that particular CGU 
from the perspective of the market participants at the 
measurement date. 
Impairment losses for CGUs reduce first the carrying 
amount of any goodwill allocated to that CGU. Any 
remaining impairment loss is charged pro rata to the 
other assets in the CGU.
With the exception of goodwill, all assets are 
subsequently reassessed for indications that an 
impairment loss previously recognised may no longer 
exist. An impairment loss is reversed if the asset’s 
or CGU’s recoverable amount exceeds its carrying 
amount.
I N V E N T O R Y 
Inventory is stated at the lower of cost and net realisable

Provisions are recognised when there is a present legal 
or constructive obligation as a result of a past event, for 
which it is probable that an outflow of economic benefit 
will be required to settle the obligation and where the 
amount can be reliably estimated. 
No liability is recognised if an outflow of economic 
resources as a result of a present obligation is not 
probable. Such situations are disclosed as contingent 
liabilities unless the outlow of resources is remote.

Financial assets
The Group classifies its financial assets at amortised 
cost. The classification depends on the purpose for 
which the financial assets were acquired. Management 
determines the classification of its financial assets at 
initial recognition.
Financial assets at amortised cost 
These assets arise principally from the provision of 
goods and services to customers (eg trade receivables), 
but also incorporate other types of financial assets where 
the objective is to hold these assets in order to collect 
contractual cash flows, and the contractual cash flows 
are solely payments of principal and interest.  They are 
initially recognised at fair value plus transaction costs 
that are directly attributable to their acquisition or 
issue, and are subsequently carried at amortised cost, 
less provision for impairment.   
The Group's financial assets measured at amortised 
cost comprise trade and other receivables, and cash 
and cash equivalents in the consolidated statement of 
financial position.  
Trade receivables
Trade and other receivables are amounts due from 
customers for services performed in the ordinary 
course of business. If collection is expected in one 
year or less (or in the normal operating cycle of the 
business, if longer) they are classified as current assets, 
if not, they are presented as non-current assets. 
Trade and other receivables are measured at the 
transaction price in accordance with IFRS 15.
The Group applies the IFRS 9 simplified approach to 
measuring expected credit losses which uses a lifetime 
expected loss allowance for all trade receivables and 
contract assets. To measure the expected credit losses, 
trade receivables and contract assets have been grouped 
based on shared credit risk characteristics and the 
days past due. The expected loss rates are based on the 
payment profiles of sales over a period of 5 years before 
31 December 2022 (2021: 31 December 2021) and 
the corresponding historical credit losses experienced 
within this period. The historical loss rates are adjusted 
to reflect current and forward-looking information 
on macroeconomic factors affecting the ability of the 
customers to settle the receivables.  The contract assets 
relate to unbilled revenue, which have performance 
obligations to be completed. Other than performance 
risk, the contract assets have substantially the same 
A C C O U N T I N G  P O L I C I E S  ( C O N T I N U E D )

6 5
risk characteristics as the trade receivables for the same 
types of contracts. The Group has therefore concluded 
that the expected loss rates for trade receivables are 
a reasonable approximation of the loss rates for the 
contract assets.
At each reporting date management assesses whether 
any events have occurred which have had a detrimental 
effect on the estimated future cash flows of the asset 
causing a financial asset to become credit-impaired. If 
the credit risk is significant a provision is posted based 
on the recoverable amount the Group is expected 
to receive per management’s assessment.  Specific 
provisions of this nature are excluded from the 
simplified credit loss calculation using the provision 
matrix.
Cash and cash equivalents
Cash and cash equivalents comprise cash in hand and 
cash deposits which are readily convertible to a known 
amount of cash.  Cash and cash equivalents in the 
statement of financial position include bank overdrafts. 
An offset position is reported as the Group has a legal 
right to offset and any settlement would be on a net 
basis. For the purposes of the cash flow statement, cash 
and cash equivalents include bank overdrafts which are 
repayable on demand and are an integral part of Group 
cash management.   
Investments
Investments in subsidiaries are recorded at cost in 
the statement of financial position.  They are tested 
for impairment when there is objective evidence of 
impairment.  Any impairment losses are recognised in 
the statement of comprehensive income in the period 
they occur.
Intercompany receivables
Impairment provisions for receivables from related 
parties and loans to related parties are recognised 
based on a forward looking expected credit loss 
model.  The methodology used to determine the 
amount of the provision is based on whether there has 
been a significant increase in credit risk since initial 
recognition of the financial asset.  For those where 
the credit risk has not increased significantly since 
initial recognition of the financial asset, twelve month 
expected credit losses along with gross interest income 
are recognised.  For those for which credit risk has 
increased significantly, lifetime expected credit losses 
along with the gross interest income are recognised. 
For those that are determined to be credit impaired, 
lifetime expected credit losses along with interest 
income on a net basis are recognised. The amount of 
any provision is recognised in the income statement 
within other operating costs.
Financial liabilities and equity
Financial liabilities and equity instruments are 
classified according to the substance of the contractual 
arrangements entered into.  
Interest-bearing government loans are recorded 
initially at their fair value, net of direct transaction 
costs. Such loans are subsequently carried at their 
amortised cost and finance charges are recognised in 
the statement of comprehensive income over the term 
of the instrument using an effective rate of interest.
An equity instrument is any contract that evidences 
a residual interest in the assets of the Group after 
deducting all of its liabilities.
Bank borrowings and loan notes
Interest-bearing loan notes and bank overdrafts 
are recorded initially at their fair value, net of direct 
transaction costs. Such instruments are subsequently 
carried at their amortised cost and finance charges are 
recognised in the statement of comprehensive income 
over the term of the instrument using an effective rate 
of interest.  
Finance charges are accounted for on an accruals basis 
to the statement of comprehensive income.  Overdrafts 
are offset against cash and cash equivalents when the 
Group has a legal right of off-set.
Trade and other payables
Trade and other payables are not interest bearing and 
are initially recognised at fair value and subsequently 
at amortised cost.
Ordinary share capital
For ordinary share capital, the par value is recognised 
in share capital and the premium in the share premium 
reserve.
P O S T - E M P L O Y M E N T  B E N E F I T S 
Defined contribution schemes
A defined contribution scheme is a pension plan 
under which the Group pays a fixed contribution 
to a scheme with an external provider.  The amount 
charged to the statement of comprehensive income in 
respect of pension costs and other post-employment 
benefits is the total of contributions payable in the year. 
Differences between contributions payable in the year 
and contributions actually paid are shown as either 
other payables or other receivables in the statement of 
financial position.  The Group has no further payment 
obligations once the contributions have been paid.
Defined benefit scheme
A defined benefit scheme is a pension plan under 
which the Group pays contributions in order to fund 
a defined amount of pension that the employees 

6 6
under the scheme will receive on retirement.  The 
cost of providing the benefits is determined using the 
projected unit credit method with actuarial valuations 
being carried out regularly. 
An asset or liability is recognised equal to the present 
value of the defined benefit obligation, adjusted for 
unrecognised past service costs and reduced by the fair 
value of plan assets.
Actuarial gains and losses are recognised in the 
statement of other comprehensive income in the 
year in which they occur, whilst expected returns on 
plan assets, servicing costs and financing costs are 
recognised in the statement of comprehensive income.
The rate used to discount the benefit obligations is 
based on market yields for high quality corporate 
bonds with terms and currencies consistent with those 
of the benefit obligations.
C L I M AT E -  R E L AT E D  M AT T E R S
Risks induced by climate changes may have future 
adverse effects on the Group’s business activities. These 
risks include transition risks (eg regulatory changes 
and reputational risks) and physical risks (even if the 
risk of physical damage is low due to the company 
activities and geographical locations).
Consistent with the prior year, as at 31 December 2022, 
the Group has not identified significant risks induced 
by climate changes that could negatively and materially 
affect the Group’s financial statements. Management 
continuously assesses the impact of climate-related 
matters.
S I G N I F I C A N T  J U D G E M E N T S 
A N D  E S T I M AT E S 
In the process of applying the Group’s accounting 
policies, which are described above, management have 
made judgements and estimations about the future 
that have the most significant effect on the amounts 
recognised in the financial statements. The estimates 
and underlying assumptions are reviewed on an on-
going basis. Revisions to accounting estimates are 
recognised in the period in which the estimate is 
revised if the revision affects only that period, or in the 
period of revision and future periods if the revision 
affects both current and future periods.
Significant judgements
The following judgments have the most significant 
effect on the financial statements.
Revenue Recognition
The Group generates revenue from the provision of 
software licences, annual support, SaaS subscriptions, 
subscription and support, professional services, 
technology 
enabled 
outsourced 
services 
and 
consultancy services. Software licences, professional 
services and annual support are often bundled together 
in a contract which do not meet the criteria to be 
distinct performance obligations. 
The promises to provide services to the customer may 
be separately identifiable. However, the services are 
highly interdependent, interrelated. The Group would 
not be able to fulfil its promise by transferring each 
service independently.
Judgement is applied in determining how many 
performance obligations there are within each 
contract and the period in which these obligations 
will be fulfilled and recognised as revenue. For SaaS 
subscription, subscription and support and annual 
support the Group determines for each contract 
whether the promise is considered to be a single 
performance obligation. The subscription and support 
are highly interdependent; customers are required to 
take both the software and support services Instem 
would not be able to provide the support services 
without the provision of the software nor provide the 
software without the support services. 
Impairment of goodwill
In 2022, the CGUs are identified by the fact they are 
separate legal entities and so have their own intangible 
and tangible assets, other current assets and generate 
cash from their products and services that are separately 
identifiable from one another. In 2023, we expect 
that the CGU composition will move in line with the 
operating segments as the operations of the Group 
will become even more integrated due to the current 
year’s reorganizational changes.The judgements were 
made in respect of the WACC, the revenue growth rate 
applied and the allocation of costs across the CGUs. 
The carrying value of goodwill must be assessed for 
impairment annually. This requires a value in use 
estimate which is dependent on estimation of future 
cash flows and the use of an appropriate discount rate 
to discount those cash flows to their present value. The 
carrying value of goodwill as at 31 December 2022 was 
£34.6m (2021: £34.6m). Refer to note 12 for further 
detail.

rates that reflect current market assessments of the time

value of money and any risks specific to the CGUs. The 
rates used to discount the future cashflows are based 
on the Business Unit pre-tax weighted average cost of 
capital. Where a CGU operates in multiple operating 
segments weighted average based on 2022 revenue of 
the relevant WACCs has been used. 
The revenue growth rates and margins are based 
on current Board-approved budgets and forecasts 
covering a period of five years. Management estimates 
are considering business growth rates, payroll and 
other cost base increases; further details are provided 
in note 12.
The data used for impairment testing procedures are 
directly linked to the Group’s latest budget, adjusted as 
necessary to exclude the effects of future reorganisations 
and asset enhancements.  The budgeted unallocated 
departmental costs are assigned to each CGU applying 
a standard methodology approved by the Board. 
Development Costs
The Group invests on a continual basis in the 
development of software for sale to third parties. 
There is a continual process of enhancements to and 
expansion of the software with judgement required 
in assessing whether the development costs meet 
the criteria for capitalisation. These judgements have 
been applied consistently year on year. In making this 
judgement, the Group evaluates, amongst other factors, 
whether there are future economic benefits beyond the 
current period, the stage at which technical feasibility 
has been achieved, management’s intention to complete 
and use or sell the product, the likelihood of success, 
availability of technical and financial resources to 
complete the development phase and management’s 
ability to measure reliably the expenditure attributable 
to the project. Judgement is therefore required in 
determining the practice for capitalising development 
costs.
Asset held for sale (AHFS) and discontinued operation 
On 1 April 2023, Instem completed the disposal of 
Samarind Limited with consideration receivable up 
to £1.0m, of which £0.8m was satisfied by cash receipt 
on completion, plus or minus estimated net cash, and 
the remaining balance of £0.2m payable contingent on 
Samarind’s future performance that would be payable 
in cash. 
The Group did not classify Samarind Limited as AHFS 
as Management concluded that the disposal was not 
highly probable to be completed under the IFRS 5 
requirement and based on the available information as 
of 31 December 2022. 
Samarind Limited was acquired 27 May 2016 without 
the view of resale but the decision to sell this unit was 
concluded when the Group reviewed and assessed their 
future strategic plans. 
As the IFRS 5 criteria were not met as of 31 December 
2022, Samarind’s Limited disposal is disclosed as a non- 
adjusting subsequent event (note 33). Additionally, 
the Consolidated financial statements and related 
notes represent results from continuing operations, 
there being no discontinued operations in the years 
presented. However, the offer price from the buyer was 
used on the impairment testing (note 12).
Estimation uncertainty
Information about estimations and assumptions that 
may have the most significant affect on recognition and 
measurement of assets, liabilities, income and expenses 
is provided below. Actual results may be substantially 
different.
Contingent consideration
Where acquisition consideration includes consideration 
contingent on performance outcomes being met, the 
consideration is valued at the acquisition date based 
on performance forecasts available at the time. Those 
forecasts are reviewed at the reporting date and the 
consideration revised where materially different  (note 
20).
Pension scheme
As stated above the Group operates a defined benefit 
pension scheme. At the end of each six monthly 
reporting period the Group seeks external expert 
actuarial advice on the assumptions to apply to the 
calculation of the scheme’s liabilities. The Group 
then engages a separate, independent firm of pension 
advisors to calculate the scheme surplus or deficit at the 
reporting date for accounting purposes. The scheme 
deficit at 31 December 2022 was £2.0m (2021: £2.0m).
Revenue Recognition
For Professional services and technology enabled 
outsourced services revenue recognition there is a 
significant estimation of the planned project hours, 
which determines the percentage of completion of 
service revenue contracts. Before the project is started, 
the project manager estimates the budgeted hours 
needed for the agreed services. If the project is expected 
to overrun then the project manager will amend the 
expected budgeted hours in accordance with the new 
available information which also mitigates the risk of 
early revenue recognition.

The Group has disaggregated revenue revenue into various categories in the following tables which are intended to 
depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.
The Group’s Chief Operating Decision Maker (CODM) has been identified as the Board of Directors. The Board 
is responsible for monitoring the performance of these operating segments as well as deciding on the allocation of 
resources to them. 
Over recent years the Group has expanded both organically and through acquisition, increasing the number of 
products and services offered and in 2020 the Group reported through three operating segments, Study Management, 
Regulatory Solutions and In Silico Solutions. During 2021 the fourth segment, Clinical Trial Acceleration (CTA), was 
established following the acquisition of d-Wise. 
There has been an internal project to enhance the quality of management information following the implementation 
of a new finance system in 2019. During 2020 this system enabled more centrally recorded costs to be allocated to 
the individual segments and that process was further developed during recent years.  The operations of the Group 
are managed centrally with group-wide functions including sales, marketing, software development, information 
technology, customer support, people & culture and finance & administration. The CTA segment already bears the 
majority of its costs directly and as such reports a lower direct contribution margin. However, during 2022 CTA has 
benefited from synergies which result in an overall improvement on the direct contribution margin.
The analysis provided below reflects costs directly attributable to the respective segments in 2022 and 2021, which 
are primarily third party costs of sale and costs of allocated employees. The remaining indirect operational costs are 
accounted for centrally and are not allocated to specific segments.
Additionally, the Group CODM is managing and monitoring the assets and liabilities as a whole since the finance 
system records the assets and liabilities by legal entity. The CODM consider that any such allocation of assets and 
liabilities to the operating segments would be arbitrary and sensitive.

a.	 Contract Balances (continued)
Amounts recoverable on contracts and deferred income are included within “trade and other receivables” and “deferred 
income” respectively on the face of the statement of financial position.
Amounts recoverable on contracts predominately relate to fulfilled obligations on service contracts where billing is in 
arrears. At the point where completed work is invoiced, a corresponding receivable is recognised.
Deferred income relates to consideration received from customers in advance of work being completed plus 
maintenance and support which is invoiced in advance.
b.	 Remaining performance obligations
The majority of the Group’s contracts are for the delivery of software and services within the next 12 months for which 
the practical expedient in paragraph 121(a) of IFRS 15 applies. 
Additionally, the Group applies the practical expedient in paragraph 121 (b) and does not need to disclose the 
information for a performance obligation as the Group recognises revenue from the satisfaction of the performance 
obligation in accordance with paragraph B16.
The following table details the value of future contracted revenue resulting from the Group’s fixed price long term 
contracts which is yet to be recognised in the income statement due to the relevant contractual performance obligations 
not being satisfied before the year end. The majority of these performance obligations are unbilled at the Balance Sheet 
date and therefore not reflected in these accounts.
The amount of revenue that will be recognised in future periods on these contracts is as follows:
Less than 1 year

Greater than 2 years
£000
Revenue expected to be recognised

c.	 Contract Costs
It is expected that commissions paid are recoverable. These have therefore been capitalised as an asset and are It is 
expected that commissions paid are not recoverable. These have therefore not been capitalised as an asset. 
As of 31 December 2022, the carrying value of costs to obtain contracts which have been capitalised is the amount of 
£nil (2021: £nil). Amortisation of £nil (2021: £nil) was recognised during the year. 
The entity has applied the practical expedient available in paragraph 94 of IFRS 15 to recognise the incremental 
costs of obtaining a contract as an expense when incurred where the amortisation period of the asset that the entity 
otherwise would have recognised is one year or less.

provision of £0.25m in respect of this dispute in the previous years.  In October 2022, Instem paid €1.48m (£1.3m), of 
which its insurer agreed to contribute €0.45m (£0.4m) resulting in a net payment due of approx. €1.0m (£0.9m). The 
insurance contribution of €0.45m (£0.4m) was included in the non-recurring income.

Nature of leasing activities in the capacity of lessee
The Group leases a number of offices in the jurisdictions from which it operates. In these jurisdictions the periodic 
rent is fixed over the lease term, with inflationary increases incorporated into the fixed payments stipulated in the 
lease agreements. Where rental agreements include market rate escalations, the lease liability is re-measured when 
the change in cash payments takes effect. The Group also leases one vehicle.  The vehicle lease comprises only fixed 
payments over the lease term. With the exception of short term leases and leases of low value underlying assets, each 
lease is reflected on the balance sheet as a right of use asset and a lease liability. 
In 2022, the lease equipment  expired and the Group has opted to continue leasing the equipment under the current 
terms, but the contract can terminated by either parties with a 2 month notice period. Therefore, the lease equipment 
qualifies as a short term lease after the expiration of the lease agreement and all the cost has been recorded in the 
consolidated statement of comprehensive income.   
Additionally, during 2022 three office leases  expired in which only one of the three was renewed for less than one year. 
Therefore that lease qualified as a short term lease.
Each lease generally imposes a restriction that, unless there is a contractual right for the Group to sublet the asset to 
another party, the right of use asset can only be used by the Group. Leases are either non cancellable or may only be 
cancelled by incurring a termination fee.  Some leases contain an option to extend the lease for a further term. For 
office leases the Group must keep those properties in a good state of repair and return the properties in their original 
condition at the end of the lease.

The Group has elected not to recognise a lease liability for short term leases (leases with an expected term of 12 months 
or less) or for leases of low value assets. Payments made under such leases are expensed on a straight-line basis.

Nature of leasing activities in the capacity of lessor
The Group also acts as a lessor in relation to a sublease of part of one of the properties rented. As the lease term is for 
the major part of the economic life of the underlying right of use asset this has been treated as a finance lease. The right 
of use asset has therefore been derecognised and a net investment in the lease recognised instead. Interest income is 
recognised on the lease receivable.

Equity-Settled Share Option Plan
The Remuneration Committee can grant options to employees of the Group. Options are granted with a fixed exercise 
price at the date of grant and the contractual life is generally ten years from the grant date. Options generally vest and 
become exercisable after three years if certain performance criteria have been met. 
There are two types of share option awards:
•	
Share options awarded to all employees as part of their annual bonus, providing they have met certain annual bonus 
targets, subject to continued employment (normally three years) and with no further performance conditions.
•	
Share options awarded to directors and senior employees generally carry profitability (EBITDA) or market-based 
performance conditions
Share options awarded to all employees
In 2020, the Group introduced the share options to all employees as part of the annual bonus award.  If the employees 
meet certain annual bonus targets, they are then subject to continued employment and passage of time (normally 
three years) with no further performance conditions. This share option has been awarded to all employees in 2020, 
2021 and 2022. 
In 2022, the Group granted 64,511 of nil-cost share options to all employees subject to continued employment, passage 
of time and no other performance conditions
Share options awarded to directors and senior employees
Share options issued to directors and senior employees generally carry profitability (EBITDA) or market-based 
performance conditions.  During 2022, the Group did not issue performance related share option awards to directors 
and senior employees. 
The following share awards issued to directors and senior employees that have not lapsed as of 31 December 2022 
relate to:
LTIP awards prior to 2018
The share options awarded prior to 2018  have vested but not lapsed as of 31 December 2022. 
2018 LTIP awards
An award under the Instem Long Term Incentive Plan (“LTIP”) was made in 2018 which entitles participants to shares 
at the end of a three year performance period based on achievement against an absolute share price performance 
condition. Awards are in the form of nil-cost share options. 
The award is in the form of 3 tranches, with performance testing at the end of each financial year over the 3 year 
performance period. A maximum of 25% of the total award vests for each of the first two tranches and a maximum of 
50% vests under the third tranche. Performance is measured at the end of each financial year and if the relevant target 
is not met the portion under that tranche lapses with no retesting.
The share options awarded in 2018  have vested but not lapsed as of 31 December 2022.

2020 LTIP awards
In addition to the share options awarded to all employees as part of the annual bonus in 2020, the Group awarded 
directors and senior employees with LTIP awards linked to performance targets.  
The performance awards vest when certain share price conditions are met. The award is in the form of 3 tranches, with 
performance tested at the end of each financial year over a 3 year performance period. A maximum of 30% of the total 
award vests for each of the first two tranches and a maximum of 40% vests under the third tranche. The performance 
criteria for this share options award were met.
2021 LTIP award with performance target
On 1 September 2021 and 27 September 2021, the Group granted awards of nil-cost options to participating employees 
which vest after three years subject to the performance conditions of either end share value or EBITDA. 
The award is in the form of 3 tranches, with performance testing at the end of each financial year over the 3 year 
performance period. A maximum of 30% of the total award vests for each of the first two tranches and a maximum of 
40% vests under the third tranche.

A charge of £1.377m (2021: £1.061m) arose in respect of share based payments.
The fair value of options granted in the year was £0.4m (2021: £2.6m).
During the year, the average share price in respect of share options exercised was £6.51 (2021: £7.90)
In 2022, the Group granted 64,511 of nil-cost share options to all employees subject to continued employment, passage

market price of Instem’s shares at the grant date. 
In 2021, the Group granted new options for 431,479 shares. The Monte-Carlo option-pricing model has been used 
where option conditions are market related and Black-Scholes where option conditions are EBITDA related. The fair

The UK corporation tax is calculated at the prevailing rate of 19%. Foreign tax liabilities are calculated at the prevailing 
tax rates applying in the overseas tax jurisdictions.
In the Spring Budget 2021, the UK Government announced that from 1 April 2023 the corporation tax rate will 
increase to 25%. As the proposal to increase the rate to 25% had been substantively enacted at the balance sheet date, 
its effects are included in the financial statements as a change from 19% to 25% on deferred tax.

The gross carrying amount and accumulated amortisation within Software includes internally generated and externally 
acquired elements. The cost of internally generated software amounts to £13.9m (2021: £10.8m) with accumulated 
amortisation of £5.7m (2021: £4.5m).  Software additions for the year include £3.0m relating to internal development 
(2021: £2.2m). 
The amortisation of software is included in “amortisation of internally generated intangibles” and the amortisation of 
acquired intangibles is included in “amortisation of intangibles arising on acquisitions”.
The increase of the gross carrying amount of goodwill in 2022 relates to a change in d-Wise contingent consideration 
paid. As per the share purchase agreement, any of d-Wise accounts receivables which were not included in the closing 
working capital, but were subsequently collected by d-Wise during the twelve month period following the date of final 
determination of closing working capital have been added and paid in the first deferred payment. As the changes in 
the fair value of the contingent consideration qualified within the measurement period adjustments of twelve months 
then the amount of £0.05m was adjusted retrospectively with corresponding adjustments against goodwill and cost 
of investments. 
An impairment loss of £0.11m was recognised on goodwill for Samarind which is part of the Regulatory Solutions 
business segment.  The fair value less cost to sell method was used to calculate the recoverable amount as the recoverable 
amount is the higher between value in use and FV less cost to sell method.

Identification of the Cash Generating Units (CGUs)
In 2022 and in previous years, the CGUs have been based on the Group's legal structure. The assessment has been 
performed at the legal entity level given the significant amount of judgement in assessing what level the cashflows are 
independent of each other. 
However, in 2023 we are considering restructuring of the CGUs in response to the ongoing changes of the Group's 
internal and external activities. We expect that the CGU composition will move in line with the operating segments 
as the operations of the Group will become even more integrated due to the current year’s reorganizational changes.
Gross carrying amount of goodwill
In 2022, the CGUs are identified by the fact that they are separate legal entities and so have their own intangible and 
tangible assets, other current assets and generate cash from their products and services that are separately identifiable 
from one another. 
The 10 CGUs identified in 2021 for impairment purposes were Instem LSS Limited Group, Instem Scientific Limited, 
Perceptive Instruments Limited, Samarind Limited, Notocord SA, Leadscope Inc, Instem Clinical Holdings Limited, 
the Edge Consultancy Limited, d-Wise Technologies Inc and PDS Pathology Data Systems Limited. 
In 2022, PDS Pathology Data Systems Limited has been fully integrated within the Group’s existing product entities 
therefore we were unable to identify the forecast cash flow for PDS only. As a result, in 2022 we identified the 9 
CGUs as Instem LSS Limited & PDS Pathology, Instem Scientific Limited, Perceptive Instruments Limited, Samarind 
Limited, Notocord SA, Leadscope Inc, Instem Clinical Holdings Limited, the Edge Consultancy Limited,and d-Wise 
Technologies Inc.

Impairment testing
The Group tests annually for impairment, or more frequently if there are indications that goodwill might be impaired.

8 6
12.	 I N TA N G I B L E  A S S E T S  ( C O N T I N U E D )
Key assumptions
The recoverable amounts of the CGUs are determined from value-in-use calculations and the fair value less cost to 
sell method. 
The key assumptions for the value in use calculations are those regarding discount rates, growth rates, margins and 
cashflows.
Additionally, the key assumption for the FV less cost to sell method is the sales multiple and price increase applied, 
which was  based on market activity at the time.
Discount rates
Management estimates discount rates using pre-tax rates that reflect current market assessments of the time value of 
money and any risks specific to the CGUs. The rates used to discount the future cashflows are based on the operating 
segment pre-tax weighted average cost of capital. Where a CGU operates in multiple operating segments weighted 
average WACCs based on revenue has been used. 
After performing further sensitivity analysis, management approved the use of the different pre-tax WACC across the 
the 9 CGUs:

operating segment. 
Where a CGU operates in multiple operating segments a weighted average was used based on the current year’s

for Perceptive Instruments, 5% for Notocord SA, 5% Instem Clinical Holdings Limited , 10% for Samarind and 10% 
for The Edge and d-Wise businesses.
For the perpetuity calculation (2028 and onwards) a 3.3%, growth rate was applied to all CGUs which management 
estimates as reasonable considering the current inflation rate, payroll and other cost base increases (2021: 2.5% 
perpetuity growth rate was applied to all CGUs) and the terminal value is calculated using the Gordon Growth Model. 
Sensitivity analysis
Management has carried out sensitivity analyses on the key assumptions used in recoverable amount calculations. 
The carrying amount of our investments includes goodwill, other intangible assets, tangible assets and right of use 
assets. 
The table below shows the headroom of recoverable amount over the carrying amount, sensitivities for the additional 
increase in the discount rate and reduction in forecast revenues. The sensitivities below show the percentage change

The value in use calculations are reliant on the accuracy of management’s forecast and the assumptions that underlie 
them as well as the discount rate and growth rates applied. 
The recoverable amount of the Instem Clinical, Samarind  and Notocord CGUs using the value-in-use calculation 
did not exceed the carrying amount of these CGUs. However, using the FV less cost to sell method to calculate 
the recoverable amount shows that the recoverable amount is more than the carrying amount for Instem Clinical 
and Notocord CGUs. As per IAS 36, the recoverable amount is the higher between value in use and FV less cost to 
sell method which means that there was no impairment charge required for both CGUs. The Goodwill related to a 
CGU, being Instem Clinical Holdings Limited, was fully impaired in 2019 therefore the CGU is not sensitive to any 
assumptions. 
The key assumptions for the FV less cost to sell method were:
- the sales multiple applied, 
- revenue lines which the sales multiple was applied and, 
- the price rate increase. 
Instem plc is a financial instrument categorised in Level 1 as it is traded on the AIM Market. However, Notocord SA 
and Clinical Limited which are direct subsidiaries of Instem plc are not traded in an active market. Both CGUs are 
included within the Study Management opearating segments.

As per IFRS 13 inputs other than quoted prices included within Level 1 that are observable for the assets either directly 
or indirectly are categorised in Level 2. Therefore, level 2 sales values of Notocord SA and Clinical Limited have been 
derived using the sales multiple comparison approach with other entities within the same operating segment of the 
Study Management. Management compared the sales multiples for Instem plc against similar entities within the same 
operating segment and decided to use 3.2 sales multiples on recurring revenue which is lower than the sales multiple 
calculated for Instem plc and the average of the entities included in the Study Management segment. 
Additionally, for the FV less cost to sell method management decided to exclude from the model any non-recurring 
revenue. Therefore, for calculating the recoverable amount management took into consideration only annual support 
and SaaS subscription and support in the FV less cost to sell model. Any other revenue types have been removed for 
the valuation assessment. Management also included a 6% price rate increase in the FV less cost to sell model which 
was lower than global inflationary pressures.
The table below shows the headroom for the key assumption on which Management has based its determination of 
the unit’s recoverable amount:

On 1 April 2023, Instem completed the transaction and disposed Samarind Limited which is part of the Regulatory 
Solutions business segment. The consideration receivable is up to £1.0m, of which £0.8m is satisfied by cash receipt 
on completion plus or minus estimated net cash and the remaining £0.2m payable contingent on Samarind Limited 
future performance payable in cash. The offer price was used for the impairment testing. 
Therefore, using the net realisable value calculations based on sales multiples the Group concluded a goodwill 
impairment of £0.11m should be recognised in 2022 in relation to Samarind Limited. 
Review of carrying value of goodwill
Following the review of the carrying value of goodwill as at 31 December 2022, which has been undertaken across the 
Group as required by IAS 36 – Impairment of Assets, the Directors have concluded that there is no need to recognise 
an impairment loss in 2022 except for Samarind Limited. 
As of 31 December 2021, the recoverable amount for each of the CGUs was measured using the value in use calculation. 
The key assumptions used for the value in use calculations were those regarding discount rates, growth rates, margins 
and cashflows. In 2021, management concluded that there are no indicators for impairment on the CGUs as the 
recoverable amount for each CGU was higher than its carrying value. However, PDS, Instem Scientific, Notocord and 
Samarind CGUs were highlighted as sensitive to increases in discount rate and fall in revenue growth rates.
The value in use calculations are reliant on the accuracy of management’s forecast and the assumptions that underlie 
them as well as the discount rate and growth rates applied.
Other intangible assets
As of 31 December 2022 and 2021, there were no indications that any other intangible assets may be impaired.

In December 2022, Instem Life Science Systems Limited (ILSS) issued ordinary shares with a value of £4.8m to Instem 
Plc in exchange for a reduction in the amount owed from ILSS to Instem Plc. The appropriate documentations were 
drafted and filed with Companies House in respect of the issue of shares. 
ILSS transferred its investment in Instem LSS Limited to Instem Plc at book value £11.7m in exchange for an 
intercompany balance. 
Finally, the amount of £1.4m relates to the share options that Instem plc awarded all employees of its subsidiaries 
subject to continued employment. Instem plc received the services indirectly through subsidiary in a form of an 
increased investment. 
An impairment provision of £1.4m has been made in 2022 against the carrying value of the investment in Samarind 
which is part of the Regulatory Solutions business segment.  
The Group tests annually for impairment against investments held.

Definition of default
A loss allowance on all financial assets is measured by considering the probability of default.
Receivables are considered to be in default based on an assessment of past payment practices over a 5 year period prior 
to 31 December 2022 and the likelihood of such overdue amounts being recovered. 
Impairment of trade receivables
The probability of default is determined at the year-end based on the ageing of the receivables and historical data 
about default rates. That data is adjusted if the Group determines that historical data is not reflective of expected 
future conditions due to changes in the nature of its customers and how they are affected by external factors such as 
economic and market conditions.
The calculated simplified expected credit loss of trade receivables is deemed immaterial in the current year (2021: 
immaterial). The directors therefore do not deem it necessary to increase the impairment provision which is in relation 
to specific credit-impaired receivables.
The average credit period taken on sale is 75 days (2021: 77 days). No interest has been charged on overdue receivables.
Before accepting any new significant customer, the Group obtains relevant credit references to assess the potential 
customer’s credit quality. Credit limits are defined by the customer.
The directors consider that the carrying amount of trade and other receivables approximates to their fair value.
Impairment of amounts owed by group companies
The Company assesses the expected credit loss in respect of group receivables based on their ability to repay and 
recover the balance.  In the absence of agreed terms this consideration is given over the expected period of repayment 
and any expected credit loss. As at the period end the Company has charged a provision of £0.2m for amounts owed by 
group companies (2021: reversed a provision of £0.02m).  The amount of the provision was £0.4m as of 31 December 
2022 (2021: £0.2m).

The Group signed a new financing arrangement with HSBC UK Bank plc in April 2022, which consists of a committed 
facility of £10.0m for general corporate purposes, which can be extended up to £20.0m if needed, subject to further 
bank approval. The financial covenants have been considered in the forecast to ensure compliance. 
The cash and cash equivalents in the 2021 statement of financial position includes a bank overdraft of £9.0m with 
NatWest Bank plc.  The bank overdraft was secured by fixed and floating charges over certain Group assets and was 
repayable on demand. An offset position was reported as the Group had a legal right to offset any settlement would 
be on a net basis. 
During 2022, the Group settled the bank overdraft balance of £9.0m with former bankers NatWest Bank plc prior to 
entering into the new financing arrangement with HSBC UK Bank plc.

Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either 
directly (i.e. as prices) or indirectly (i.e. derived from prices).
Level 3: Inputs for the asset or liability that are not based on observable market data (unobservable input).

Measurement of fair value of financial instruments
The following valuation technique is used for instruments categorised as Level 3:
Contingent consideration (Level 3) 
As of 31 December 2022, the fair value of contingent consideration related to the acquisitions of The Edge and d-Wise 
which were acquired in March 2021 and April 2021 respectively. The contingent considerations were estimated using 
a present value technique. 
The Edge’s contingent consideration of £1.0m fair value was estimated in 2021 based on the approved cash flow 
projections and forecast discounted at 30.9% to adjust for risk. The probability weighted cash outflows before discounting 
are £1.0m and reflect management’s estimate of a 100% probability that the Edge’s target level of profitability will be 
achieved. The profitability target was confirmed during the period. 
Finally, d-Wise’s contingent consideration of US$1.4m (£1.2m) fair value was estimated in 2021 based on the approved 
cash flow projections and forecast discounted at 18.6% to adjust for risk. The probability weighted cash outflows 
before discounting are US$1.5m (£1.2m) and reflect management’s estimate of a 100% probability that  d-Wise’s target 
level of profitability will be achieved. The profitability target was confirmed during the period.

CREDIT RISK
Financial risk management
Management aims to minimise the risk of credit losses. The Group’s financial assets are bank balances and cash and 
trade and other receivables, which represent the Group’s maximum exposure to credit risk in relation to financial 
assets.
The credit risk in respect of cash balances held with banks are only with major reputable financial institutions. 
The Group’s credit risk is primarily attributable to its trade receivables and the Group has policies in place to ensure 
that sales of products and services are made to customers with appropriate creditworthiness. The Group generates 
external revenue from no customer that individually amounts to more than 10% of the Group revenue. At the 2022 
year end the Group had a maximum credit risk exposure of £18.3m (2021: £14.9m).
The amounts presented in the statement of financial position are net of impairment provisions.
The Group’s exposure to losses from defaults on trade receivables is reduced due to contractual terms which require 
installation, training, annual licensing and support fees to be invoiced and paid annually in advance. Note 16 sets out 
the impairment provision for credit losses on trade receivables and the ageing analysis of overdue trade receivables. 
There were no impairment losses recognised on other financial assets.
The Group undertakes procedures to determine whether there has been a significant increase in the credit risk of 
its other receivables, including group balances, since their initial recognition.  Where these procedures identify a 
significant increase in credit risk, the loss allowance is measured based on the risk of a default occurring over the 
expected life of the instrument rather than considering only the default events expected within 12 months of the year-
end.

LIQUIDITY RISK 
Financial risk management
Liquidity risk is the risk that the Group will not be able to meet its financial commitments as they fall due.
The Group’s objective is to ensure that adequate facilities are available through use of bank overdrafts and leases. 
The Group manages liquidity risk through regular cash flow forecasting and monitoring of cash flows, management 
review, and regular review of working capital and costs.
The Group regularly monitors its available headroom under its borrowing facilities. On 8 April 2022, the Group 
signed a new financing arrangement which consists of a committed facility of £10.0m with HSBC UK Bank plc to 
support the Group's working capital needs and its acquisition strategy, which can be extended up to £20.0m if needed, 
subject to further bank approval. As of 31 December 2022, the borrowing facility was undrawn however the relevant 
covenant calculations have been calculated and considered. The Group had positive cash reserves of £14.0m at the 
2022 year end, in addition to the £10.0m undrawn working capital facility, although £3.2m of the cash was held in 
bank accounts in China, where it has been traditionally harder to repatriate funds quickly.

MARKET RISK
Market risk - Foreign currency risk
The Group operates internationally and is exposed to foreign currency risk on transactions denominated in a currency 
other than the functional currency and on the translation of the statement of financial position and statement of 
comprehensive income of foreign operations into Sterling.  The currencies giving rise to this risk are primarily US 
dollars.  The Group has both cash inflows and outflows in this currency that create a natural hedge.  
In managing currency risks the Group aims to reduce the impact of short-term fluctuations on the Group’s cash 
inflows and outflows in a foreign currency.  
Over the longer term, changes in foreign exchange could have an impact on consolidation of foreign subsidiaries 
earnings.  A 10% decrease in the average value of Sterling against the US dollar would have resulted in an increase in 
the Group’s profit before tax by approximately £0.7m (2021: £0.6m).

Interest rate risk 
The Group operates an interest rate policy designed to minimise interest costs and reduce volatility in reported 
earnings.
As of 31 December 2022, the indications are that the UK bank base interest rate could materially change over the next 
12 months. During 2022, the UK base rate increased by 3.25 percentage points to 3.5%. On the basis of the Group cash 
position at 31 December 2022 and assuming no other changes occur (such as material changes in currency exchange 
rates) a change in interest rates should not have a material impact on net interest income/(expense). Finally as of 31 
December 2022, the Group’s new financing arrangement which consists of a committed facility of £10.0m with HSBC 
UK Bank plc to support the Group's working capital needs and its acquisition strategy was undrawn.

Other timing differences are predominantly related to share based payment and capitalised development. 
Management have recognised deferred tax assets in relation to tax losses based on forecast profitability of the Group 
companies concerned.
Unrecognised tax losses not included at 31 December 2022 were £22.0m (2021: £3.0m) due to uncertainty over the 
timing of the recoverability of these losses.

The Group provides post-employment benefits through various defined contribution schemes and a closed UK 
defined benefit scheme.
Defined contribution pension schemes
The Group pays fixed contributions into independent entities in relation to several retirement plans and insurances for 
individual employees. The Group has no legal or constructive obligations to pay contributions in addition to its fixed 
contributions, which are recognised as an expense in the period that related employee services are received.
Defined benefit pension scheme
The Group also operates a legacy defined benefit pension arrangement called the Instem LSS Pension Scheme (the 
Scheme). The Scheme provides benefits based on final salary and length of service on retirement, leaving service or 
death. This scheme was closed to new members with effect from 8 October 2001. 
The Scheme is subject to the Statutory Funding Objective under the Pensions Act 2004. A valuation of the Scheme 
is carried out at least once every three years to determine whether the Statutory Funding Objective is met. As part of 
the process, the Group must agree with the Trustees of the Scheme the contributions to be paid to meet the Statutory 
Funding Objective. The future contributions required to meet the Statutory Funding Objective do not currently affect 
the statement of financial position of the Scheme in these accounts. 
The most recent comprehensive actuarial valuation of the Scheme was carried out as at 5 April 2020 and the next 
valuation of the Scheme is due as at 5 April 2023. In the event that the valuation reveals a larger deficit than expected 
the Group may be required to increase contributions above those set out in the current Schedule of Contributions. 
Conversely, if the position is better than expected, it is possible that contributions may be reduced. 
The following Schedule of Contributions has been prepared by the Trustees of the Scheme after obtaining the advice 
of the Scheme Actuary appointed by the Trustees. The contributions are intended to clear the Scheme deficit by 30 
September 2026 and were agreed in June 2021.

The Group currently expects to pay contributions of £518,000 in the year to 31 December 2023 as the £50,000 was 
already paid in the year to 31 December 2022. The cash contributions have been considered in the future cash flow 
and going concern review. 
The weighted average duration of the defined benefit obligation is expected to be around 15 years.
The Scheme is managed by a Board of Trustees appointed in part by the Group and part from elections by members of 
the Scheme. The Trustees have responsibility for obtaining valuations of the Scheme, administering benefit payments 
and investing the Scheme’s assets. The Trustees delegate some of these functions to their professional advisors where 
appropriate.

25.	 P O S T- E M P L O Y M E N T  B E N E F I T S  ( C O N T I N U E D )
The Scheme exposes the Group to a number of risks: 
•	
Investment risk. The Scheme holds investments in asset classes, such as equities, which have volatile market values 
and while these assets are expected to provide the real returns over the long-term, the short-term volatility can 
cause additional funding to be required if a deficit emerges.
•	
Interest rate risk. The Scheme’s liabilities are assessed using market yields on high quality corporate bonds to 
discount the liabilities. As the Scheme holds assets such as equities the value of the assets and liabilities may not 
move in the same way.
•	
Inflation risk. A significant proportion of the benefits under the Scheme are linked to inflation. Although the 
Scheme’s assets are expected to provide a good hedge against inflation over the long-term, movements over the 
short-term could lead to deficits emerging.
•	
Mortality risk. In the event that members live longer than assumed a deficit will emerge in the Scheme.
There were no Scheme amendments, curtailments or settlements during the year.
The employer pays the Pension Protection Fund levy each year in respect of the scheme.  It is intended that all other 
expenses associated with the running of the Scheme will be met from the Scheme’s assets.
Risk mitigation strategies
The investment manager has previously been instructed as to the permissible ranges for asset allocations as set out in 
the Scheme’s current Statement of Investment Principles. Over the year, the Scheme invested in a portfolio of liability-
driven assets, designed to hedge against interest rate and inflation risk.
The net interest on the net defined benefit liability was determined by considering the expected returns available on 
the assets underlying the current investment portfolio.  Expected yields on bonds are based on gross redemption 
yields at the reporting date whilst the expected returns on the equity and property investments reflect the long-term 
real rates of return experienced in the respective markets.

As previously announced the Group created a provision of £0.25m in respect of historical contract disputes that arose 
in 2017 with a a maximum exposure of approximately €4.5m. The maximum exposure includes additional claims 
for consequential losses. During the year an additional provision of €1.2m (£1m) was provided for full and final 
settlement of this contract dispute. 
In October 2022, the Group paid €1.48m (£1.3m), of which its insurer agreed to contribute €0.45m (£0.4m) resulting 
in a net payment due of approx. €1.0m (£0.9m).
The balance of £0.04m relates to the general provision that PDS provided for warranty and remained unchanged as of 
31 December 2022 based on management estimates.

Basic and diluted earnings per share
Basic earnings per share are calculated by dividing the profit attributable to ordinary shareholders by the weighted 
average number of ordinary shares in issue during the year.  Diluted earnings per share is calculated by adjusting the 
weighted number of ordinary shares outstanding to assume conversion of all dilutive potential shares arising from the 
share option scheme. 
The deferred and contingently issuable shares in relation to d-Wise acquisition which could potentially dilute the basic 
EPS in the future were not included in the calculation of diluted EPS because they are antidilutive for the period of 
2021. The deferred and contingently issuable shares in relation to the d-Wise acquisition were settled in April 2022. 
The dilutive impact of the share options is calculated by determining the number of shares that could have been 
acquired at fair value (determined as the average market share price of the Company’s shares) minus the issue price. 
The number of the ordinary shares that could have been acquired at their average market price during the period are 
ignored. However, the shares that would generate no proceeds and would not have effect on profit or loss attributable 
to ordinary shares outstanding are included.

Adjusted earnings per share
Adjusted earnings per share is calculated after adjusting for the effect of foreign currency exchange and the unwinding 
of the finance liability included in finance income/(costs), non-recurring items, amortisation of intangibles on 
acquisitions and impairment of goodwill. The adjusted profit after tax has been amended in 2022 to ensure that the 
foreign exchange movements and the unwinding of the finance liability do not impact and distort the earnings per 
share calculation.
Diluted adjusted earnings per share is calculated by adjusting the weighted number of ordinary shares outstanding 
to assume conversion of all dilutive potential shares arising from the share option scheme.  The dilutive impact of the 
share options is calculated by determining the number of shares that could have been acquired at fair value (determined 
as the average market share price of the Company’s shares) based on the monetary value of the subscription rights 
attached to the outstanding share options.
