Dear shareholder 
Progress happens together
Our global team is motivated by a mission to make Abcam the 
most influential company in life sciences. We exist to influence 
the community of discovery, and to shorten the time from first 
discovery to impact on society.
Over the last 25 years, Abcam has had an important role in 
providing tools and molecules to discovery scientists. As we grew 
our internal innovation capability and capacity over the last 10 
years, we have learned to create products that can consistently 
go the distance from discovery research to clinical applications. 
Beyond our leaps forward to scale product innovation, we have 
discovered that by bringing empathy and understanding to how 
science makes this journey, we have become a more integral 
part to making progress happen together.
As a company, we are opening opportunities to connect people, 
organisations, and stages of scientific progress together to 
bring efficiency and better outcomes to society. This mindset 
is shaping our brand, culture, partnerships, and our daily 
interactions with hundreds of thousands of dedicated life 
scientists around the world in Universities, Research Institutes, 
Hospitals, Government Organisations, Biopharma Organisations, 
Diagnostics, and a broad range of companies working to ensure 
society is healthy and safe.
Our success has been enabled by the tireless efforts of our 
approximately 1,800 employees working to advance science. 
We have created and continue to nurture a vibrant and 
dynamic culture through diversity, equity, and inclusion, thereby 
differentiating the Company and making us a great place to 
work. We believe that our growth is powered through our people, 
and our commitment to delivering excellence powers the pillars 
of our strategy:
	–
Sustain and extend our antibody and digital leadership
	–
Drive continued expansion into complementary market 
adjacencies
	–
Build organisational scalability and sustain value creation
Attacking constraints to durable growth
We have just completed the third year of the five-year strategic 
plan we set out in 2019. The implementation of this plan 
continues to attack internal constraints to enable our company 
to sustain long-term profitable growth that is higher than 
underlying market growth rates.
As we enter the final two years of our strategic cycle, we are 
spending more and more of our time refining what we have 
installed. We continue to allocate capital to areas that are 
critical to that effort: product innovation; digital transformation; 
and operational scaling. Many of these changes will support the 
Company’s growth for decades to come. In 2022, we completed 
three of these major milestones:
Change in listing
We consolidated all Abcam share trading on the Nasdaq stock 
exchange in 2022 with almost universal support of shareholders. 
The Company’s 2005 IPO on the AIM market funded the start of 
Abcam’s globalisation. Seventeen years later, 95% of company 
demand, approximately 60% of employees, and over 50% 
of shareholders are located outside of the UK. This was an 
incredibly successful period of global growth for the Company, 
and we are grateful for the flexibility that the AIM market 
provided in those formative years. With the sole Nasdaq listing, 
we are entering a new phase that allows greater access to 
industry savvy investors who want to invest in the Company’s life 
science growth story.
Core enterprise system upgrade
Abcam was built from scratch twenty-five years ago primarily 
as a software company to bring a better buying experience to 
researchers working with antibodies. Every process and aspect 
of how the Company historically operated, was custom built 
and programmed into a legacy home-grown enterprise system, 
controlling everything from the website content to how cash 
was collected.
By 2015, I could see that this core enterprise operating system 
was going to constrain our growth and posed a risk to the 
business. That system had fundamental and non-scalable 
design issues with its architecture, data, and performance, all of 
which were under strain from our growth. We needed change to 
enable Abcam to succeed in its strategy as an in-house product 
innovator/manufacturer, to become more scalable and efficient, 
to bring a modern personalised website buying experience, 
and to comply with the internal control environment of a 
publicly listed company. The business case for this programme 
was rooted in the fact that we had no choice but to make 
this change.
I am delighted that in 2022 we introduced a scalable and more 
robust Oracle Cloud ERP platform to grow Abcam for many 
years to come. With over 70 system integrations, we replaced 
the Company’s legacy technology and processes during H2 
2022. To say that reaching this milestone was challenging is 
an understatement.
Even with the expert help of IBM Consulting and Oracle 
Software, the go-live transition did not go as well as planned. 
Over September-October 2022, we experienced disruption to 
our ability to serve and invoice customers. During that period, 
our primary focus was to do everything we could to support 
customers whilst resolving data, software, and design issues that 
were compromising performance. We have apologised to those 
affected and we appreciate their understanding of the one-off 
nature of this change.

There was also a financial impact on our revenue (orders 
shipped and invoiced fell short of orders received) and cash 
(ability to invoice customers and collect cash for orders 
shipped). We continued to see strong demand for Abcam 
products throughout H2, and as we improved operations, the 
business returned to normal exiting the year. As with any process, 
we will seek to make further improvements to delivery on promise 
and invoicing as we learn to utilise and refine our new systems.
The major disruption to customers and our business are largely 
behind us and we look ahead to serving customers more as 
normal in 2023. We are taking all that we can learn from it to 
remain a durable and long-term growth company. We are 
confident these changes have strengthened Abcam and will 
allow us to scale and innovate in ways we could not otherwise 
have done.
Footprint/facilities/BioVision integration
In 2022, we continued our focus on expanding our global 
footprint with expansion in Waltham, Amsterdam, and Singapore. 
We have nearly completed building out Waltham’s approximate 
100,000 square feet for assay kits, our fastest growing product 
line. This expansion provided capacity to grow and made it 
possible to fully integrate the BioVision business we acquired in 
2021, whilst exiting their facility in Milpitas, CA in 2023. Expansion 
into Amsterdam improved our digital innovation capabilities, 
and Singapore ensures our ability to better serve the Asia-Pacific 
region. These initiatives increase our efficiency, add needed 
capacity, reduce risk, and ultimately enable the Company with 
increased scale.
2022 Performance
In 2022, Abcam continued the path to becoming a leading Life 
Sciences company offering in-house products and services. Our 
focus on innovation has helped drive new product development 
resulting in us achieving market share gains over the past few 
years. We have been recognised once again by CiteAb with the 
most industry awards including best acquisition (BioVision). We 
continue to build out capabilities to sustain our ability to drive 
long term and profitable growth. In addition, new and existing 
partnerships have extended Abcam research tools into clinical 
applications, accelerating our impact on drug discovery for the 
benefit on society.
The biggest contributor to Abcam’s growth and value is enabled 
by sales of our in-house products, including BioVision, and the 
main reason we are winning more market share is the portfolio of 
proprietary products developed and manufactured at Abcam. 
This burgeoning in-house library of recombinant antibodies, 
assays, conjugation kits, proteins, and cell lines are offering 
customers the right products, to the right pathways, with a promise 
to go the distance from discovery to clinic. Customer demand for 
this portfolio drove in-house revenue to £243.9m in 2022 (2021: 
£193.1m), equivalent to 18% annual CER growth and 26% on 
a reported basis, including BioVision. Our investment of 23% of 
revenue (own product) back into R&D enables sustainable growth 
and higher customer satisfaction in these areas.
2022 was a challenging year. We faced inflationary pressures 
on our costs, supply chain disruptions and the ongoing impact 
from COVID-19, particularly in China. However, even in this 
environment we delivered major change programmes aligned 
to our strategic priorities.
The Company completed business transformation projects 
including opening a Singapore office, full integration of BioVision, 
installing an Oracle Cloud ERP system and making a complete 
transition of our traded shares from AIM to Nasdaq. From a 
financial perspective, we achieved mid-teens reported revenue 
growth (high-single digit CER revenue growth), expanded our 
adjusted operating profit margin, to over 21%, and delivered 
adjusted diluted earnings per share growth of approximately 
21%. As we look ahead to the successful completion of our five-
year growth plan, I could not be more excited about the road 
ahead.
New product development
The success of our products depends on rigorous testing to drive 
product performance and reliability. Our internal investments in 
R&D and manufacturing have resulted in us achieving better 
control of out-of-the box quality, first time every time to the delight 
of scientists. We have over 400 full-time employees working 
in Research and Development, over 150 with PhDs, that are 
developing new products to further customer efforts in scientific 
development and advancement in areas such as Oncology, 
Immunology, and Neurobiology.
Our teams once again had a successful year of in-house 
new product development with ongoing progress across all 
product lines. As science moves from the use of Next Generation 
Sequencing to understand basic building blocks of human 
DNA, it becomes more vital now to understand the disease 
pathways and root cause of disease. Our product portfolio 
enables proteomics research by our customers and partners. The 
study of cellular mechanisms such as the role of signalling and 
regulatory proteins in biological pathways – ultimately leading 
to diagnostics and treatments for diseases such as cancer, 
immunodeficiencies and neurodegenerative disorders – are 
within our grasp. Enabling advancements in science is a core 
element of our innovation efforts.
Investments have helped innovate new products in antibodies, 
proteins, cell lines, conjugation kits, and immunoassays. 
We continue to build out into adjacent categories such as 
cellular and biochemical assay capabilities from the BioVision 
acquisition. We believe that their full suite of assay offerings 
is differentiated to better support the dual/mixed approach 
to drug discovery (target-based and phenotypic approach) 
being undertaken by BioPharma. In 2022, we are proud to 
have launched nearly 2,000 new Antibodies, approximately 
200 new bioactive proteins and over 1,500 engineered cell line 
products. In total, our team delivered approximately 5,500 new 
products, and achieved over 99% customer product satisfaction 
(measured by customer complaint rates); this is a testament to 
our team’s abilities and focus on out-of-the-box quality. These 
new product introductions combine to meet two objectives:

fill unmet needs in research and increase product quality. 
Continuing our focus on quality, we have added product 
validation using biophysical quality controls (a biopharma 
control check) and we will continue to monitor and delist third 
party supplied products that do not meet our quality standards. 
Together, these actions have substantially improved Abcam’s 
quality and our overall brand preference.
New in-house products introduced since 2019 represented 
approximately 10% of 2022 revenue and our own-product 
revenues (including Custom Products & Licencing), plus 
BioVision, contributed approximately 67% of total revenue in 
the last 12 months enabling favourable margin mix. According 
to the most recently available industry data, these innovations 
and other initiatives have led Abcam to become the most cited 
antibody company worldwide. Abcam products were cited 
approximately 80,000 times in scientific journals in 2021 and the 
business now has a citation share of over 23%, with continued 
share gains over the previous year (source: CiteAb, based on 
over 300,000 recorded citations for 2021 as of February 2023).
Partnerships
We furthered our efforts on ‘Abcam Inside’ by strengthening our 
position as a leading discovery partner to organisations looking 
to access high quality antibodies and antibody expertise for 
commercial use within their products and assays.
We established several new platform partnerships during the 
period while expanding existing co-development programmes 
with current partners, including recently announced strategic 
partnerships with WuXi Diagnostics, and Roche Holding AG. 
We continue to grow our specialty antibody portfolio – signing 
18 new outbound commercial agreements in 2022 that have 
the potential to lead to new diagnostic or therapeutic tools in 
years to come. The combined total of 33 new agreements and 
amendments also reflects the expansion of existing relationships.
In 2022, over 1,200 of our antibodies were validated for 
commercial use on third party platforms or as diagnostic tools. 
The total number of Abcam antibody clones commercialised to 
date is now over 2,000. We believe both areas remain significant 
long-term opportunities for the Group.
Diverse Team
We continue to work toward a more inclusive and diverse 
global team. Our organisation has access to and leads a wide 
range of employee resource groups to support diverse interests 
and needs. With their input, we designed and introduced 
enhanced family leave benefits in 2022 to support parents with 
growing families.
We also made progress in our multi-year goals to enhance 
gender diversity. In our most recent data, the Company has 57% 
women overall, 46% of our leaders are women, and we added a 
fourth female director to the board in 2022.
Attractive Outlook for 2023 and 2024
As we look ahead to the final stages and successful completion 
of our five-year growth plan, we are focused on ensuring the 
significant investment made in our innovation capabilities, 
systems and processes, facilities, and people support our 
long‑term growth aspirations.
In 2023, our priorities for the year will largely focus on refining 
what we have installed, learning from the market, continued 
development of new products to grow our revenue, and 
returning to historical levels of profitability by 2024 consistent with 
our stated goals.
I could not be more excited about the prospects ahead. Our 
confidence in the performance of the business is unwavering, 
and we continue to expect to achieve our revenue target of 
£450m-£525m by 2024.
Once again, I want to thank our global team for their dedication, 
our customers for the trust they place in us, as well as our Board 
of Directors and our shareholders for their continued support.

Our Served Markets
 
The life science industry 
which Abcam serves is 
experiencing increases 
in research funding and 
capital investment to support 
the growth of collaborative 
and global biomedical 
discovery networks.
The Group’s addressable markets are currently 
estimated to total approximately $8bn. This 
figure is comprised of an addressable market for 
proteomic research reagents of approximately 
$3bn and an addressable market for out-
licenced antibody development for diagnostic 
and therapeutic companies intended for clinical 
use, totalling approximately $5bn. Further 
information on our markets can be found on 
the investor section of our website at corporate.
abcam.com/investors/our-markets.
We expect the continuation of a number of 
industry forces to sustain long-term market 
growth trends across both research-use only 
(RUO) and clinical use markets, resulting in 
increasing long-term demand for our products 
and services.
Major long-term industry and macro drivers, 
include:
–	The funding environment for biomedical 
research
–	The increasing focus on research reproducibility
–	The growing significance of genomic and 
proteomic research
–	Demographic and epidemiological trends
–	The expansion and prioritisation of R&D 
in China
As a global supplier of high-quality life science 
research reagents and tools, Abcam helps life 
scientists to advance scientific discovery through 
their research. Our protein binding reagents, tools 
and solutions are increasingly used by academic, 
pharmaceutical and biotechnology organisations across 
a range of applications and research fields including 
oncology, cardiovascular, cell biology, epigenetics, 
infectious diseases, metabolism, developmental 
biology, immunology, microbiology, neuroscience, 
signal transduction and stem cell research.
Therefore, growth in the number of scientists conducting 
protein research around the world, and the support for 
those scientists – through increased research funding 
and capital investment, as well as new innovations 
that allow them to increase productivity – are all 
important contributors to the Group’s long-term growth 
prospects. The credibility and influence of a life science 
company, such as Abcam, is, in part, determined 
by the number of times their products are cited in 
scientific papers. The number of times our products 
are cited has grown consistently year-on-year since 
2010. According to industry data provider CiteAb, 
Abcam was the most cited company for antibodies 
globally in 2021, with approximately 80,000 citations, 
a market share of over 23% (based on over 300,000 
registered citations for 2021 as of February 2023).
Antibodies are also a critical component in many 
in-vitro diagnostic assays, including companion 
diagnostics, and can also be used as therapeutic 
agents for the treatment of diseases, including cancers 
and immune-related diseases. As well as developing 
these antibodies internally, biopharmaceutical 
and diagnostic organisations are increasingly 
outsourcing the initial discovery and development 
of antibodies to third party organisations able to 
provide these services on a contract basis.
In recent years, we have increased our focus on this area 
of the market, through both the custom development 
of new antibodies and the out-licencing of our existing 
antibodies to biopharmaceutical and diagnostic 
companies, extending the commercial application 
of our products into these markets. We believe that 
we are well positioned to leverage our expertise in 
protein binding reagents to support clinical and 
instrument platforms, capturing greater market share 
and driving growth within these markets as a result.

Our Business Model
As a global life sciences 
company, we provide 
highly validated antibodies 
and biological tools to the 
scientific community
The success of our customers’ work, from basic research 
to translational science, diagnostics, and therapeutic 
clinical programmes, relies on rigorous product quality, 
performance, and reliability.
Underlying our value chain is a set of defining strengths 
which set us apart from our competitors: our data 
and leading digital presence; our brand leadership 
in research use antibodies; our differentiated product 
innovation platform and product offering; our global 
scale and distribution platform; and our global team 
and culture.
Our strategy leverages these strengths to drive long-
term profitable growth, which in turn drives free cash 
flow and return on invested capital – and ultimately 
attractive returns for shareholders. Sustainable value 
creation means investing for the long-term.
Given the abundance of market opportunities for growth, 
in 2019 we set out a Five-Year Growth Plan to increase the 
pace of investment to accelerate our growth potential 
and generate long-term shareholder value.
Sustainable value creation also means operating in a 
responsible manner, which maximises positive impact 
and reduces negative impact. That is why at the heart 
of our business model and vision to grow our business 
is a commitment to increase our positive social 
impact whilst reducing our environmental footprint, 
in turn contributing to the United Nations Sustainable 
Development Goals.
Our strategy and business model continue to deliver 
growth that is consistent, competitive, profitable, 
and responsible. Notwithstanding the impact of the 
COVID-19 pandemic, in the nine years to 31 December 
2022, the Group delivered double digit compound 
annual sales growth. Over the same period, the number 
of times our antibodies were cited by researchers 
worldwide grew from ~14,000, to approximately 80,000 
annually, reflecting our growing influence within 
the scientific community.

Our mission is to provide life science 
researchers with highly validated products 
and services to advance biological research 
and achieve their goals faster. We do this by 
continuously innovating and providing our 
customers with high-quality tools, together 
with expert customer support. Our product 
offering includes an extensive portfolio of 
antibodies and related protein research 
tools that are fundamental to our customers’ 
research and experimental workflow. Our 
customers are primarily researchers in 
academic institutions, research institutes 
and pharmaceutical, biotechnology and 
diagnostics companies.
Headquartered in Cambridge, United Kingdom, we operate 
across 13 locations around the world, supported by our 
world‑class team of approximately 1,800 employees, including 
over 150 with PhDs, and have served customers in over 
130 countries.
Our addressable market can be broadly classified into two 
categories, based on the application of our products and type 
of customer they serve:
	–
Research use only proteomic tools. These products include 
protein binding reagents, such as primary and secondary 
antibodies and singleplex immunoassays, and related 
reagents, such as conjugation kits, proteins, peptides, lysates, 
cell lines and biochemicals. Our research products are used 
to help detect, quantify, visualize, and modify proteins in 
scientific research experiments, and enable our customers 
to develop insights about targets and pathways of interest. 
Our customers include academic labs for scientific research 
and clinical labs in pharmaceutical and biotechnology 
companies working in the drug discovery and diagnostic 
markets. Our catalogue revenue, the substantial majority of 
which is purchased for RUO, accounted for 94% of our total 
revenue for the year ended 31 December 2022 (2021: 94%).
	–
Antibody development for clinical application. In 
recent years, through the custom development of new 
antibodies and the out-licensing of our existing antibodies 
to biopharmaceutical and diagnostic companies, we 
have extended the commercial potential of our products 
into these markets. The substantial majority of our Custom 
Products and Licensing revenue, which includes custom 
development services, in vitro diagnostic medical devices 
(“IVD”) sales and royalty and license income, is generated 
from these activities, and accounted for 6% of our total 
revenue for the year ended 31 December 2022 (2021: 6%).
We have developed an industry leading innovation platform 
that is informed by data analytics, research area specialists and 
the relationships we have built with our customers, enable us to 
anticipate and align our innovation efforts with our customers’ 
research priorities. Today, nearly all of our primary antibody 
innovation pipeline is driven by our proprietary algorithms 
that interrogate a wide variety of internal and external data 
sources, including research literature and our web data, 
to predict product and market demand, which inform our 
development efforts. We leverage this data to anticipate which 
tools researchers will need in the future in order to help advance 
their research, as well as to identify breakthrough opportunities in 
areas where there is a lack of high-quality products or where we 
identify custom opportunities in collaboration with our customers.
We offer a large and differentiated portfolio of approximately 
90,000 products as of 31 December 2022. Our flexible sourcing 
model enables us to grow our product offering in line with 
researchers’ needs. This is achieved by developing and 
manufacturing in-house products, as well as sourcing products 
from our suppliers. We demand high product quality standards 
from our suppliers, and we enhance the utility of these products 
for our customers by providing additional data and product 
validation, as well as making them available through our global 
distribution platform and customer service. Over the last several 
years, we have increased focus on the development of in-house 
products for research areas we expect to have high demand 
for. Notably, our portfolio of proprietary recombinant monoclonal 
antibodies and immunoassays, which are recognized for their 
market leading high specificity, sensitivity and consistency, 
approximates to 29,000 as of 31 December 2022. Alongside 
these highly validated protein binders, we offer additional related 
tools and reagents that customers require to study biological 
pathways and diseases. This focus has seen our proprietary 
portfolio grow to represent 67% of our total revenue for the year 
ended 31 December 2022, compared to 61% of our total revenue 
in the year ended 31 December 2021. We are continuously 
expanding our portfolio to provide our customers with additional 
solutions and further expand within our addressable markets.
We make our extensive product characterization and validation 
data available to our customers across our portfolio. This data is 
sourced by our inhouse laboratories, our network of collaborators 
and independent consumer product reviews. Researchers use 
this to be able to select the right product for their highly specific 
needs. Stringent quality control and validation processes are 
carried out by our global laboratories to check the activity, 
stability, and performance of our products. Whether it is 
antibodies, kits, proteins or other products, the validation process 
is continuous, and the data obtained is made available on our 
product datasheets and in our protocols. We are continuing to 
invest in product validation to raise quality standards.

Financial statements
Since 2001, we have sold our products and services to 
customers in over 130 countries through a variety of channels, 
including our ecommerce sites, a network of distributors and a 
targeted field sales team. As of 31 December 2022, we estimate 
a global population of approximately one million life science 
researchers based within academic, research, government, and 
biopharmaceutical organizations that we aim to serve. As of 
31 December 2022, we had seven manufacturing facilities and 
a global distribution network that enables prompt delivery to our 
customers, with orders generally shipped within 24 to 48 hours of 
ordering. Our multilingual scientific support team, which is mostly 
comprised of individuals with PhDs, together with our customer 
support team are available to help customers around the world 
with technical and order-related queries.
We recorded revenue of £361.7 million, operating loss for the year 
of £10.1 million and Adjusted Operating Profit of £76.3 million 
for the year ended 31 December 2022. For the year ended 
31 December 2022, our revenue grew by 15% on a reported basis 
and 8% on a CER revenue growth basis compared to the year 
ended 31 December 2021.1
Products and Services
Catalogue Products
We offer a broad selection of products in our catalogue to 
support research on proteins in biological pathways. Ultimately, 
findings from this research can translate into treatments for 
diseases such as cancer and immune deficiency disorders.
In the year ended 31 December 2022, catalogue sales 
comprised 94% of our total revenue.
Principal catalogue product lines include the following:
	
–
Primary and secondary antibodies
We provide antibodies intended for basic research, or those 
that are typically used in academic, pharmaceutical and 
biotechnology laboratories to investigate fundamental 
scientific questions. High-quality research antibodies are 
critical to scientists’ research and their ability to reproduce 
experiments, as unreliable research reagents lead to wasted 
time and money. We strive to offer high-quality antibodies 
that provide specificity, sensitivity, and consistency, which 
help to increase confidence in research outcomes and 
reduce waste across the industry.
	
–
Conjugated antibodies and conjugation kits
Conjugation is the process of attaching a label to an 
antibody to enable visualization and measurement. 
Labels come in many forms, such as enzymes, fluorescent 
molecules, and metals. We offer directly conjugated 
primary antibodies and antibody conjugation labelling 
kits, which enable customers to conjugate their 
own antibodies.

 Please see Financial Highlights and Key Performance Indicator table on page 2.
	
–
Singleplex immunoassays
An immunoassay is a test that uses one or more antibodies 
to detect and quantify a molecule of interest within a sample. 
We offer ELISA kits, which are based on reliable and optimized 
matched antibody pairs. Our matched antibody pairs are 
recombinant, monoclonal antibodies that are developed 
and optimized for use in relevant sample types like plasma 
and serum for reliable performance.
Our antibodies and antibody pairs are also made available 
to a range of third parties developing either novel multiplex 
platforms or upgrading their existing platforms.
Proteins and peptides
We offer a range of peptides and proteins, which include 
cytokines (initiate an immune response), growth factors 
(used for culturing cells in a laboratory), and enzymes 
(catalyze reactions). Scientists use these proteins and peptides 
as part of more complex experiments to test how cells and 
organisms function.
Edited cell lines and lysates
Cell lines and lysates are an important emerging tool for 
antibody validation by both our customers and in our own 
labs. We offer a range of knockout cell lines and lysates, which 
are used for our in-house validation needs and are also made 
available to our customers for their own research.
Other products
We offer a wide variety of other products, including cellular 
activity kits, biochemicals and cell signalling pathway 
tools, which help researchers to find molecules needed for 
their research.
Custom Products and Licensing
Alongside our catalogue offering we provide a comprehensive 
range of solutions for custom antibody, protein, and cell line 
development. Our custom antibody development incorporates 
initial evaluation and target identification through to the delivery 
of purified, fit for purpose antibodies for research, diagnostic or 
therapeutic application.
In other situations, antibodies that are already available on 
our online catalogue for research use purposes are requested 
for potential clinical use. In such case, we work with those 
customers to provide a license for commercial use on third-
party platforms or within in vitro diagnostics. Antibody based 
IVD assays are tools typically used in a clinical setting, such 
as a hospital or medical institute laboratory, to help diagnose 
a disease or condition. These tools are used on patient 
samples (such as blood, urine, or tissue) and help clinicians 
to diagnose or assess the progression of a disease. IVD assays 
can also provide information on the type of treatment to use 
and assist with disease prognosis.
For the year ended 31 December 2022, Custom Products and 
Licensing revenue comprised 6% of our total revenue.

Research & Development
We are constantly searching for new ways to bring more products 
in-house and to improve our internal innovation capabilities 
through the use of data analytics. Especially where we see that 
customer needs are not being fulfilled or if there is demand for a 
higher quality alternative. We are engaged in ongoing research 
and development in all our major product lines and believe 
that our future success depends, to a large extent, on our ability 
to continue to serve our customers’ needs and keep pace with 
changing technologies. In the year ended 31 December 2022 we 
developed approximately 5,500 new products.
Underpinning our differentiated and innovative product 
development capability is a strong and dedicated team of 
experts, which we increased by sixteen after we acquired 
BioVision in October 2021.
Manufacturing and Distribution
As of 31 December 2022, we have seven manufacturing facilities 
strategically located across four continents in close proximity to 
many of the largest clusters of life science research hubs. This 
enhances supply chain efficiency and ensures that, in most 
cases, our customers are able to have the product they require 
for their research within 24 to 48 hours of ordering. In October 
2021, we acquired BioVision, which added a manufacturing 
facility in Milpitas, California.
We have the expertise and government licenses to manage 
multiple controlled environments globally, enabling us to 
handle highly regulated chemicals and other materials in a 
compliant manner. We are committed to maintaining industry 
leading standards for our manufacturing processes at our 
global facilities in order to continue to provide our high-quality 
products to our customers. We follow strict global quality control 
procedures across all of our manufacturing facilities to ensure 
consistent lot-to-lot performance for our customers. We also 
impose the same quality standards on our third-party suppliers, 
to ensure that our customers receive a consistently high level of 
quality across products offered in our catalogue.
Our manufacturing site, based in Hangzhou, China, is ISO 
9001:2015 certified and all other sites work to these standards. 
The facility of our IVD group, located in Fremont, California, is 
registered as a medical device establishment with the FDA and 
is subject to the FDA’s Quality System Regulation (“QSR”) and 
in compliance with ISO 13485:2016. This facility has a Device 
Manufacturing License granted by the California Department of 
Public Health.
Customers
We have three primary categories of customers including: 
academic institutions, research institutions, and pharmaceutical, 
biotechnology and diagnostic companies. While across all 
categories our end customers are life science researchers, 
customer orders are received from individual scientists ordering 
on their own behalf, laboratory managers ordering on behalf 
of their lab teams, purchasing managers ordering on behalf of 
several labs, or central procurement teams ordering on behalf 
of labs, divisions or entire organizations. Orders can be received 
directly, through a variety of means, or via one of our distributors. 
As of 31 December 2022, 45% of our total revenue came from the 
Americas, with 55% of our total revenue originating from all other 
countries in which we operate.
As of 31 December 2022, we estimate a worldwide population 
of approximately one million life science researchers based 
within academic, research, government, and biopharmaceutical 
organizations that we aim to serve. For the year ended 
31 December 2022, excluding sales through our distribution 
partners, approximately 61% of our catalogue revenue was 
derived from academic institutions, and the remaining 
approximately 39% was derived from our other customers 
including research institutes and biopharmaceutical, 
biotechnology, and diagnostics companies. Our sales are widely 
distributed, and no single customer accounted for more than 3% 
of our revenue for the year ended 31 December 2022.
Sales Channels
Since 2001, we have sold our products and services to 
customers in over 130 countries through a variety of channels, 
including our ecommerce sites, a network of distributors and 
a targeted field sales team. These channels provide customers 
the flexibility to purchase our products quickly and from any 
location in the world. We continue to focus on ways to improve 
the ease and efficiency with which customers are able to find 
and access the products and services they need. In addition 
to our digital platform, we have an extensive range of offline 
channels, which include our global sales and customer and 
scientific support teams and Abcam and other industry hosted 
conferences, among others. In the year ended 31 December 
2022, approximately 70% of our total revenue was sold through 
our direct channels.
Suppliers
We maintain a large network of product suppliers and 
collaborators. We select suppliers that adhere to high-quality 
and ethical standards, and we monitor their performance 
through audits, reviewing the progress of any corrective action 
plans and measuring of key performance indicators. If any of 
our suppliers do not comply with our high quality and ethical 
standards or underperform on key performance indicators, we 
reassess our relationship with such supplier. In some cases, we 
delist a noncomplying third-party product from our platform and 
supply channels. Our product suppliers benefit from our global 
distribution network, digital platform, and recognized brand 
to support the sales of their products. Our suppliers are widely 
distributed, with no single third-party supplier accounting for more 
than 2% of our revenue for the year ended 31 December 2022.
We are transparent about how we work in terms of ethics, quality, 
the environment, and general business principles, and aim to 
build long term collaborative relationships based on trust.

Strategic Report
Corporate governance
Financial statements
Competition
We operate in a highly competitive environment with a diverse 
and fragmented base of competitors, many of whom focus on 
specific regions, customers and/or specific product segments. 
While many customers weigh and balance competitive factors 
differently in our industry, many focus upon consistency of 
product quality and performance, service and delivery, breadth 
of product line, consistency across products, price, customer 
support, online capabilities, and the ability to meet the special 
and local needs of our customers. Market success is primarily 
dependent upon product innovation and quality, selection 
of products, price, and reputation. For certain customers, 
competition is driven not only by the product quality across 
our industry, but also by the adaptability of the supplier as a 
developmental and commercial partner. We rely on our scale, 
expertise, deep customer access, depth of product offering, 
marketing strategies and sales force, acquisition strategy, 
financial profile, and management team to deliver superior 
solutions to our customers and provide extensive market 
channel access to our suppliers.
Although only a few competitors have significant global scale 
and liquidity, the marketplace for reagents and biological 
tools, including RUO antibody suppliers, is fragmented and 
competitive, reflecting the wide range of technologies and 
applications that use these products and the unregulated 
status of the market.
Intellectual Property and Licenses
Our success depends in part upon our ability to protect our 
core technologies and intellectual property. We own significant 
intellectual property, including patents, patent applications, 
technology, trade secrets, knowhow, copyrights and trademarks 
in the United States and other countries. Abcam is also licensed 
under domestic and foreign patents, patent applications, 
technology, trade secrets, knowhow, copyrights, and trademarks 
owned by others. In the aggregate, these intellectual property 
assets and licenses are of material importance to our business. 
We believe, however, that no single patent, technology, 
trademark, intellectual property asset or license is material in 
relation to Abcam’s business.
Training and Development
We offer a range of online and offline development opportunities 
to support personal and provisional growth. For the year ended 
31 December 2022, approximately 2,000 internal courses were 
delivered online and offline, and over 17,500 digital content items 
were delivered via our curated learning platform, Abcampus. 
In the year ended 31 December 2022, we offered 11 different 
apprenticeship standards at levels two to seven in the United 
Kingdom and had 24 active apprentices including 13 senior 
leaders masters apprenticeships and 6 digital and technology 
solutions degree apprenticeships. Our employees rate us in the 
top 10% for growth of benchmarked companies in our monthly 
employee survey. We aim to create a positive, collaborative 
culture, and we want to ensure everyone is aware of the 
contribution they can make across our business. We recognize 
that the work environment has an impact on productivity, 
innovation, and collaboration, which is why we have dedicated 
resources to building new facilities. We want employees to be 
engaged and motivated and have opportunities to develop 
and progress.
Compensation and Benefits
Overall, we believe that we maintain a good relationship with 
our employees.
We believe rewarding employees fairly, equitably, and 
competitively is crucial to attracting, retaining, and maintaining 
a motivated workforce. To that end, we offer a comprehensive 
and wide-ranging compensation and benefits program 
(which vary by region) including market competitive pay, 
broad based share awards and bonuses, healthcare benefits, 
pension contributions, paid time off and family leave, flexible 
work schedules, wellbeing education and resources. With an 
emphasis on flexibility and personalization, each year we review 
and implement enhancements to ensure our benefits are 
inclusive and meet of the needs of our people.
In particular, we are focused on fostering an ‘owner mindset’ 
throughout the organization through greater share ownership. 
A central initiative of this effort was our AbShare scheme, an 
all-employee share plan. The scheme vested in November 2021, 
with over 90% of our global employees becoming shareholders 
as a result. Two subsequent successor plans, the “Profitable 
Growth Incentive Plan” for senior leaders, and the “Abcam 
Growth Plan” for all other employees, have since been launched, 
which aligns our people with our customers and shareholders.

I am proud that as we continue to help 
life scientists achieve their mission faster, 
Abcam continues to be a good steward 
of capital, sustainable entity, and good 
corporate citizen. We remain unwavering 
in our commitment to our long-term 
sustainability commitments covering four 
priority areas: Product, People, Partners, 
and Planet. I am excited by the progress 
our Company is making. Here are some 
of the highlights of the year:
Planet
At Abcam, we are passionate about the environment; it is 
part of our culture, and manifests in a variety of ways across 
the business. In our global sites, we now have environmental 
champions and committees, who have made significant positive 
impact through new initiatives. Notable examples include 
the reduction of energy consumed by cold storage units and 
laboratories, through reduction of freezers and revisions to lab 
shutdown processes, respectively. We also reuse and recycle 
single-use laboratory plastics.
Abcam have helped avoid 956 tonnes of waste from going to 
landfill by using alternative disposal methods such as recycling, 
reuse, and energy from waste. Our APAC Marketing, Logistics and 
global Digital teams collaborated to launch a 1-page datasheet 
with QR code. This not only improves customer experience 
in receiving and checking goods but has also allowed us to 
reduce the amount of paper included in our product shipments. 
Our passions extend beyond the workplace. We regularly 
support community initiatives that address societal inequities.
Looking forward, we are preparing towards ISO14001 
accreditation for our Cambridge, UK and Waltham, US sites, 
as well as carrying out our third phase Energy Savings 
Opportunity Scheme (ESOS) audit in our Cambridge, UK site. 
Actions that surface will be replicated across sites, where 
applicable. Following some successful pilot programs to recycle 
laboratory plastics, we are looking into sustainable supply chain 
opportunities with partners.
Partners
Through our partners, we have a wider scope to influence within 
the industry. Our tender and third party contract templates have 
been updated to include requirements regarding Environmental, 
Social & Governance (ESG). In addition, 36 EcoVadis 
assessments were launched in the year. Targeted sustainability 
initiatives with specific suppliers are planned for 2023 as well as 
new supplier assessments with EcoVadis.
Product
Through each scientific publication and clinical applications that 
we enable through our products, Abcam brings societal benefit 
by positively impacting public health. Our commitment to an 
ascites-free catalogue has been a multi-year ongoing initiative 
to remove regulatory risk from our catalogue, reduce animal use 
in our replenishment processes, and deliver reagents with the 
highest batch-to-batch consistency for repeatability in scientific 
research. To date, we have eliminated all ascites reagents from 
our Primary Antibody portfolio and continue to monitor all product 
categories for ascites-based components, in order to successfully 
transition customers to higher performing alternatives.
People
An important aspect of our corporate culture is creating an 
engaging and inclusive environment where our people thrive. 
Not just in their roles, but in doing what they love for the benefit 
of all stakeholders. We value authenticity and encourage our 
employees to celebrate their identities openly. This is supported 
through our Employee Resource Groups (ERGs). Following 
the official launch of our two newest ERGs (for Mental Health 
and Disability/Neurodiversity), the total number now comes 
to seven. Our ERGs have a done a huge amount of work to 
increase awareness on Diversity, Equity & Inclusion (DEI), and to 
drive the development of inclusive policies and interventions. 
This includes introduction of the Transitioning at Work policy, 
which gives line managers valuable information about the 
nature of support that their direct reports require when they are 
transitioning. We have also introduced new guidance on support 
for menopause as well as additional leave for fertility treatment 
and premature child loss. To ensure fairness and equality 
across our processes, we have undertaken a successful global 
diversity monitoring program and have also incorporated equal 
opportunities monitoring into our new recruitment platform. 
We have also signed up to the Disability Confident Employer 
Scheme. Furthermore, Abcam is now a member of Business 
Disability Forum, Business In The Community, and Stonewall. These 
organisations will guide us in our continued efforts to employ 
best practices to embed inclusion across our organisation. 
Abcam participated in its first ever inclusion index submission, 
as part of application to the Stonewall Workplace Equality Index. 
In our monthly all employee survey, we rank in the top 5% of the 
benchmark employers for inclusion.
Our employee efforts have resulted in the Company winning 
three prizes at the EXA 22 employee experience awards:
	–
Gold for Learning and Development
	–
Silver for Best Company to work for
	–
Bronze for Reward and Recognition
Developing Sustainable Impact

In addition, we have won The Firm’s Recruitment Effectiveness 
Award, and the Best Innovation in Internal Recruitment Award at 
the Tiara Talent Acquisition Awards. But we are most grateful for 
recognition from our dedicated and highly engaged workforce. 
It is this strong engagement which powers our business. Our 
monthly survey gives leaders feedback and tools to make sure 
they understand how their teams are feeling.
Our people strategy focuses on realising and unlocking all of 
the potential of our talented global team:
	–
Raising trust and engagement through wellbeing
	–
Creating a personalised and human employee experience 
and culture
	–
Accelerating our growth through brilliant people
	–
Driving business decisions through people insight
Getting this right positions Abcam to serve our customers better, 
and pave the way for new discoveries, faster. Progress happens 
together.
Engaging with stakeholders through transparent and 
regular communication
Strong relationships and effective communication with 
our stakeholders are a key part of delivering on our 
Sustainability strategy.
Our second sustainability report, ‘Our Impact 2021’, our 
Gender Pay Gap Report, our Modern Slavery and Tax Strategy 
Statements, and our UN Global Compact Progress Report are 
all available for stakeholders to view on our website.
In addition to conversations with our employees, customers, and 
partners to understand their needs, we regularly engage with 
investors and ESG analysts to get their perspectives, and during 
the course of 2022 it has been my pleasure to meet a number 
of stakeholders to both share our approach and understand 
perspectives. Although we have made meaningful steps/progress, 
there is always more that can be done. Stakeholders are welcome 
to contact us via the email address sustainability@abcam.com.

All available emissions sources required under The Companies 
(Directors’ Report) and Limited Liability Partnerships (Energy and 
Carbon Report) Regulations 2018 are included. Going beyond 
compliance for SECR, we report on our Scope 1, 2 & 3 emissions 
globally, rather than just the UK. The disclosure also extends to 
fugitive emissions from the operation of facilities and chemical 
process emissions in the form of CO2 (liquid and dry ice).
The calculation for greenhouse gas emissions estimates 
covers all material sources of emissions for which Abcam is 
responsible. Scope 1 relates to emissions from activities for which 
the Company own or control, including combustion of fuel 
and operation of facilities. This includes all our UK and global 
operations that are consolidated in the financial statement, the 
offices leased to conduct these operations, activities for which 
Abcam own and control, and business travel carried out in 
employee-owned vehicles and rental vehicles. Scope 2 relates 
to emissions from the purchase of electricity, heat, steam, and 
cooling for use at the Group’s locations, all of which have been 
converted using government published conversion factors. 
Scope 3 captures all upstream and downstream emissions 
related to our business.
Note that this disclosure covers a 12-month period from 
1 January 2022 to 31 December 2022, compared with an 
18-month period from 1 July 2020 to 31 December 2021. 
Year‑over-year comparisons have been determined by 
annualising last year’s figures to a 12-month basis.

SECR performance trends
	– Total SECR Scope 1, 2 & 3 emissions of 
102.3 ktCO2e globally (12 months to 
31 December 2022).
	– Scope 3 emissions comprise 96% of total 
emissions.
	– A 98% increase in Purchased Goods and 
Services was associated with growth of 
the business and includes purchase of 
chemicals, construction etc.
	– YoY business travel grew supernormally 
high due to COVID-related restrictions in 
the previous year.
	– Scope 1 and 2 consumption (kWh) and 
associated carbon figures (tCO2e) increased 
29% YoY and 32% YoY, respectively.
	– There is significant reduction (-18%) in 
consumption in the UK, where BMS and 
other energy efficiency measures have 
been implemented.
	– Excluding the UK, this was a 56% 
increase. The US, where Abcam is 
growing significantly organically and 
through acquisitions, accounts for most 
of this increase.
	– Scope 1 & 2 carbon intensity (tCO2e per 
£m sales revenue) increased from 11.3 
(18 months to 31 December 2021) to 12.7 
(12 months to 31 December 2022). This is a 
13% increase, which reflects an increase in 
the revenue of the business plus an increase 
in our Scope 1 and 2 emissions due to 
acquisitions and organic growth.
	– 14% of energy sourced from renewables, 
saving over 118 tCO2e (12 months to 
31 December 2022).
	– By using alternative disposal methods such 
as recycling, reuse, and energy from waste, 
Abcam avoided 956 tonnes of waste going 
to landfill, in the year to 31 December 2022. 
This saving represented 52% of Abcam’s 
total waste by weight.
	– Largest waste stream generated was 
mixed recycling. It equated to 877 tonnes 
and 48% of total waste by weight.
	– The second largest waste category was 
575 tonnes incinerated regulated waste. 
Equating to 31% of total waste by weight.
	– 190 tonnes of waste sent to landfill.

Revenue
Our revenue primarily consists of catalogue product sales. 
Revenue from sales of goods, including revenue generated from 
products sold from our catalogue and IVD products, is recognized 
upon the earlier of delivery to the customer or the point at which 
the customer takes control of the goods, if this is sooner. We also 
earn revenue from custom products and licensing, which we call 
our Custom Products and Licensing revenue. Custom product 
and service revenue, which can be the provision of a service or 
the development of products for customers, is recognized at the 
point at which a milestone, as defined in the contract, has been 
completed. Every milestone is typically aligned to a customer 
deliverable. For example, the amount of services provided, a 
deliverable arising from the services or the number of products 
successfully developed and provided to the customers, and 
accordingly is considered to be a performance obligation. 
Each milestone has a defined transaction price. If it is identified 
that the costs will exceed contract revenue, the expected loss is 
recognized as an expense immediately. License fee income is 
recognized upon delivery of the licensed technology where our 
continued performance or future research and development 
services are not required. Royalty revenue is recognized on an 
accrual basis based on the contractual terms and the substance 
of the agreements with the counterparty, provided that the 
amount can be reliably measured, and it is probable that the 
economic benefit will flow to us.
We recorded revenue of £361.7 million, an operating loss 
for the year of £10.1 million and adjusted operating profit of 
£76.3 million for the year ended 31 December 2022. Revenue, 
including acquisitions, grew approximately 8% on a CER basis 
as reported revenues grew by approximately 15% for the year 
ended 31 December 2022, as compared to the year ended 
31 December 2021.1 During the year, two factors impacted 
revenue growth. First, the implementation of the new Oracle 
Cloud ERP system disrupted revenues in September and October. 
Second, China revenues were impacted by COVID-19 controls 
and outbreaks. Based on the differences between forecasts and 
actual results we estimate the aggregate impact to sales was 
approximately £30 million. We estimate this headwind negatively 
impacted revenue growth by approximately 10% on a reported 
and 9% on our CER growth rates.
We present our results of operations in the same way that we 
manage our business, evaluate our performance, and allocate our 
resources. We have determined that we only have one reportable 
segment, which is the sale of antibodies and related products.

Adjusted gross profit and gross margin
Our gross profit and gross margin may fluctuate from 
period to period. Such fluctuations may be influenced by 
changes in product mix and changes in foreign currency 
exchange rates. Gross margin is impacted by the mix of 
our products growing at different rates or differing growth 
rates within different geographic territories, as well as 
future acquisitions and productivity improvements to our 
manufacturing sites as we introduce more automation.
Reported gross profit margin of 74.8%. We recorded adjusted 
gross profit of £273.2 million for the year ended 31 December 
2022, equal to 75.5% adjusted gross margin as compared to 
£227.7 million equal to 72.2% adjusted gross margin in the prior 
period. Improvement in adjusted gross margins was enabled 
by favourable mix of in-house product sales and the acquisition 
impact from BioVision.
Selling, general and administrative expenses
Selling, general and administrative expenses primarily consist of 
salaries and related benefits. Other general and administrative 
costs include marketing expenses, facility related costs and 
professional services fees for auditing, tax, and general legal 
services, as well as expenses associated with the requirements of 
being a listed public company on Nasdaq.
Selling, general and administrative expenses increased by 
£34.8 million, to £224.5 million for the year ended 31 December 
2022 compared to £189.7 million for the year ended 31 December 
2021. Selling, general and administrative expenses before 
adjusted items, share-based payments and amortization of 
acquired intangibles increased by £25.7 million, to £176.3 million 
for the year ended December 31, 2022 compared to 
£150.6 million for the year ended December 31, 2021. The overall 
increase was due to an increase in salaries, IT systems and 
licenses, higher travel costs off a lower COVID base and increased 
headcount for our in-house teams and the inclusion of BioVision.

Research and Development expenses
Research activities, which are the early stages of product 
development, are expensed as incurred up until products reach 
commercial feasibility, after which point such development costs 
are capitalized and amortized over the anticipated commercial 
life of the asset. Such research and development expenses, which 
are expected to increase in the future, consist of salary related 
benefits, costs of related facilities, materials and equipment, costs 
associated with obtaining and maintaining patents and other 
intellectual property, depreciation of research and development 
of specific assets and amortization of capitalized research 
and development projects, and include an offset in respect 
of research and development tax credits as described further 
below. Development activities generally relate to creating new 
products, creating variations of existing products, modifying 
existing products to meet new applications, or developing new 
technology platforms from which to derive new products. But the 
latter costs are only capitalized once commercial feasibility is 
attained whereby this category of capitalized cost is described as 
Internally Developed Technology (“IDT”).
We carry out extensive research and development activities, 
and as a result, we benefit in the United Kingdom from HMRC’s 
Research and Development Expenditure Credit (“RDEC”), which 
provides relief against UK corporation tax. Broadly, RDECs provide 
a tax credit currently equal to 13% of “qualifying research and 
development expenditure” made from April 1, 2020 by certain 
companies where certain criteria are met. Based on criteria 
established by HMRC, a portion of expenditures incurred in 
relation to our research and development and manufacturing 
development activities are eligible for RDEC relief. Our qualifying 
research and development expenditures largely consist of 
employment costs for research staff, consumables and certain 
internal overhead costs incurred as part of research projects 
for which we do not receive revenue and are loss generating. 
To the extent a company cannot utilize the RDEC against UK 
corporation tax, then certain rules apply that allow the RDEC 
to reduce the tax liability of certain specified taxes. And to the 
extent it is not possible to utilize the RDEC in full, then the net tax 
credit is repaid to the Company by HMRC.
Research and development expenses increased by £28.3 million, 
to £56.1 million for the year ended 31 December 2022 compared 
to £27.8 million for the year ended 31 December 2021. Research 
and development expenses before adjusted items, share based 
payments and amortization of acquisition intangibles increased 
by £3.9 million, or 23.4%, to £20.6 million, for the year ended 
31 December 2022 compared to £16.7 million for the year ended 
31 December 2021. The overall increase was due to increases in 
salary, and related costs associated to the BioVision acquisition.
Adjusted Items
Adjusted items, share-based payments and amortisation of 
acquisition intangibles were £86.4 million for the year ended 
31 December 2022, compared to £53.3 million for the year 
ended 31 December 2021. This primary increase was driven 
by the impairment of assets held for sale. During the year 
ended 31 December 2022, the assets relating to Firefly BioWorks 
multiplex and assay technology were actively marketed and 
classified as held for sale on our balance sheet during the year. 
We were not successful in locating a buyer and a decision was 
made to discontinue our investment in these products and 
technology resulting in an impairment charge of £18.3 million. 
Acquisition, integration and reorganisation costs of £15.7 million 
for the year ended 31 December 2022 compared to £13.0 million 
for the year ended 31 December 2021, primarily related to 
the integration of BioVision, which was acquired in 2021, and 
expenses related to the cancellation of our ordinary shares from 
trading on AIM which was effective from 14 December2022.
Share-based payment expenses, as well as the associated 
employment taxes, of £26.2 million are included within this 
category in the year ended 31 December 2022 compared 
to £20.0 million for the year ended 31 December 2021. This 
was driven by the full year impact of a new share-based 
payment scheme under which grants were made mid-way 
through 2021. Other expenses consisted of amortisation of 
fair value adjustments of £2.7 million relating to the fair value 
of the inventory acquired in connection with our integration 
of BioVision, compared to £3.1 million in the year ended 
31 December 2021; systems process improvement costs of 
£6.6 million compared to £7.0 million for the year ended 
31 December 2021, related to the work performed on the Oracle 
Cloud ERP project in upgrading our IT systems that did not 
qualify to be capitalised and an impairment of a software asset 
developed as part of the Oracle Cloud ERP project that was no 
longer required; and amortisation of acquisition intangibles of 
£16.9 million for the year ended 31 December 2022, compared 
to £9.1 million for the year ended 31 December 2021.

Financial Overview continued
Net Finance Expenses
Finance costs consist mainly of interest expense on our 
revolving credit facility (“RCF”) that was drawn down during 
the year ended 31 December 2022 and is treated as short term 
debt. Finance costs additionally include the amortization of 
upfront fees incurred in setting up our RCF and other related 
facility fees, such as those for non-utilization. We have no other 
borrowings upon which interest could be incurred. Finance costs 
also include interest expense representing the unwinding of 
discounted lease liabilities in respect of assets now presented on 
our balance sheet in accordance with IFRS 16, which became 
effective on 1 July, 2019.
Tax
Our tax expense or credit consists of income taxes, with UK 
income being taxed at the UK rate of tax and taxation for other 
jurisdictions calculated at the rates prevailing in each respective 
jurisdiction. Tax also includes the unwinding of temporary 
differences caused mainly by the manner in which intangible 
assets related to acquisitions are recognized, and therefore 
amortized, in our consolidated financial statements compared 
to the individual entity financial statements, which is the basis 
upon which taxation is calculated.
We also benefit from the UK “Patent Box” regime that allows profits 
attributable to revenue from patents registered in the United 
Kingdom or European Union or patented products to be taxed 
at an effective rate of 10.0%, rather than the usual UK statutory 
rate of 19.0%.
Liquidity, cash, and cash equivalents
We assess our liquidity, in part, through our operations and an 
analysis of our working capital together with our other sources 
of liquidity, primarily our RCF. As of 31 December 2022, we had 
cash and cash equivalents of £89.0 million, with drawings of 
£119.6 million.
In February 2019, we entered into an RCF with a syndicate 
of banks for £200.0 million, with an additional £100.0 million 
accordion option, providing us with additional financial flexibility 
for future acquisitions. We drew down £120.0 million on the RCF 
during the year ended 31 December 2021 to fund the BioVision 
acquisition in October 2021, and our RCF remained drawn in this 
amount as of 31 December 2022. The term of this initial RCF was 
to expire on 31 January 2024.
In March 2023, we entered into a new RCF with a syndicate of 
banks for £300.0 million with no accordion option. The new RCF 
has a term of 4 years, with the option to extend for one further 
year. The amount of £120.0 million drawn down on our initial 
facility was rolled forward into the new facility.
Our working capital balance, which is comprised of inventories, 
trade and other receivables and trade and other payables, 
was £84.2 million, an increase of £34.5 million from £49.7 million 
for the year ended 31December 2021.  The increase in working 
capital was directly impacted by the implementation of the new 
Oracle Cloud ERP system and COVID-19 in China. Specifically, 
inventory and accounts receivables balances were negatively 
impacted by our inability to ship and invoice product sales and 
collect cash on a timely basis.

To deliver on our purpose, and for our 
business to thrive, we need to have strong 
relationships with our stakeholders – our 
customers, employees, partners, shareholders 
and communities and wider society.
We have to understand the needs of 
these stakeholders, and the most effective 
way to engage with them, as meeting 
and exceeding their expectations is an 
essential part of our value creation model 
and strategy.
How we discharged our s172 duties
In accordance with the Companies Act 2006 (the Act) as 
amended by the Companies (Miscellaneous Reporting) 
Regulations 2018, the Directors provide this statement to 
describe how they have engaged with and had regard 
to the interests of our key stakeholders when performing 
their duty to promote the success of the Company, 
under section 172 of the Act. The Directors consider, both 
individually and together, that they have acted in the 
way they consider, in good faith, would be most likely to 
promote the success of the Company for the benefit of its 
members as a whole (having regard to the stakeholders 
and matters set out in Section 172 of the Companies 
Act 2006) in the decisions taken during the year ended 
31 December 2022.
Given the importance of our stakeholders and the 
impact they have on our strategy, reputation and the 
Company’s long-term success, consideration has been 
given to them throughout this Annual Report.
Understanding the views and values of all our 
stakeholders is critical to Abcam’s success, and we value 
their broad range of perspectives. Details on how the 
business and the Board engage with our stakeholders 
are outlined over the following five pages.
At every Board meeting, each agenda item is specifically 
cross-referenced to all relevant responsibilities under 
section 172 of the Act and also to our key risks. The Board 
recognises that each decision made will not always 
result in a positive outcome for each of our stakeholders. 
However, by having good governance procedures in 
place for decision making, the Board aims to make 
sure that its decisions maintain a high standard of 
business conduct.

Stakeholder engagement 
during the period
Abcam’s principal 
stakeholders and the 
impact we have upon 
them, including details of 
how we have engaged 
with our employees, is 
discussed on pages 21 to 
25. Not all information 
is reported directly to 
the Board and not all 
engagement takes place 
directly with the Board. 
However, the output of 
this engagement informs 
business-level decisions, 
with an overview of 
developments and 
relevant feedback being 
reported to the Board.
Our Customers
Who they are and why 
they matter to us?
We serve a global population of 
approximately one million research 
scientists based within academic, 
research, government and 
biopharmaceutical organisations.
We exist to serve our customers. They 
are vital to the continued growth and 
development of our business. It is 
critical that we listen to them and offer 
the products and services they need.
How we engage 
with them
We engage with customers through 
the use of industry surveys delivered 
after interactions to obtain close 
to real-time feedback on our 
performance. We also regularly 
conduct focus groups with our 
customers and have key account 
managers who proactively engage 
with key customers to assess their 
needs and the challenges they face.
The Board receives updates on 
customer engagement at each Board 
meeting. All major decisions take 
the impact on the customers into 
consideration.
What has mattered 
to them this year and 
our response
Customers continue to tell us that 
product quality, service response speed 
and quality scientific support remain 
key drivers of loyalty and advocacy. 
Researchers’ continue to need access 
to a secure and reliable supply of 
high-quality products, with detailed 
and reliable data to save time and 
ensure that experiments are conclusive, 
consistent and repeatable.
Customers increasingly want an 
efficient and streamlined ordering 
experience that allows them to place 
and receive their orders, whether 
standard products or more customised 
solutions, quickly and conveniently.
We have responded to these 
requirements by:
	–
introducing a scalable and more 
robust Oracle Cloud ERP platform 
which will allow us to serve 
increasing customer demand for 
many years to come;
	–
supporting our customers whilst 
resolving data, software, and design 
issues, arising while we transitioned 
to our enterprise system upgrade;
	–
continuing to innovate and improve 
the tools, data and purchasing 
experience for customers;
	–
expanding our product offering to 
add complementary and adjacent 
technologies; and
	–
investing in our customer service 
and scientific support teams.

Our section 172 statement continued
Who they are and why 
they matter to us?
We currently employee approximately 
1,800 people globally, including 
full‑time, part-time employees and 
day‑rate contractors.
Our people are our most important 
asset. They are fundamental to our 
continued success, as their skill and 
dedication enable us to fulfil our vision 
and purpose.
How we engage 
with them
We carry out ‘pulse’ employee surveys 
every month to hear feedback and 
receive timely and actionable data on 
employee engagement. This is both 
qualitative and quantitative feedback.
We operate seven Employee Resource 
Groups aligned to our Diversity & 
Inclusion strategy. A sponsor from 
the Executive Leadership Team sits in 
each group.
Our CEO, CFO and other members of 
the Executive Leadership Team hold 
regular virtual town halls where the 
conversation is two-way.
The Board receives updates on 
employee engagement at each 
Board meeting and hold a regular 
‘Meet the Board’ session which gives 
all employees the opportunity to 
question, and hear directly from, 
Board members.
Our Employees
What has mattered to 
them this year and 
our response
Our employees continue to tell us they 
want a great career, and a positive 
and motivating work environment, all 
underpinned by a supportive culture 
in a sector that has positive impact 
in society.
Diversity and inclusion have always 
been important to our employees and 
we have increased participation in 
our Employee Resource Groups, with 
each group focused on different areas 
of diversity and inclusion, including 
the introduction in 2022 of a mental 
health focussed ERG. This year we 
also updated our global Family Leave 
Policy to provide additional leave for 
fertility treatment and premature child 
loss, and launched a Transitioning at 
Work Policy, which gives line managers 
valuable information about the nature 
of support that their direct reports 
require when they are transitioning. 
An element of management’s 
compensation is linked to improving 
ESG more broadly (but mostly diversity 
and inclusion) throughout Abcam.
Having an attractive total rewards 
package remains important for our 
global team and the Abcam Profitable 
Growth Incentive Plan continues to 
incentivize approximately 150 senior 
leaders across the business, and our 
Abcam Growth Plan, offers share 
schemes for all other permanent 
employees. These plans align 
employees’ rewards with Abcam’s 
strategic goals.
We have embedded an employee 
centred approach to performance 
management which we call 
Performance with Purpose. Colleagues 
set annual goals and then managers 
provide regular informal feedback to 
support and drive performance against 
these goals with an emphasis on praise 
and recognition as well as resolving 
any performance issues. The results 
have been impressive with significant 
increases in our growth (135%), learning 
(70%), mentoring (114%) and manager 
support (61%) engagement net 
promoter scores over the last 2 years.
We offer significant support to our 
leaders to enable them to grow and 
develop, through stretch assignments 
and increased internal mobility, 
through investing in leaders’ coaching 
and mentoring capability, through 
our Leading with Purpose leadership 
workshops (33 were delivered in 2022) 
and through Abcampus, our curated 
online learning system with over 35,000 
topics. We have relationships in place 
with educational partners to support 
people development. 14 colleagues 
completed external qualifications 
in 2022 with educational partners, 
six colleagues completed a project 
management accreditation, and 
14 colleagues were actively completing 
an apprenticeship.

Who they are and why 
they matter to us?
Our partners include those who 
have a direct working or contractual 
relationship, or share a mutual interest 
with us. This includes our strategic 
business partners, our suppliers, service 
providers, industry organisations, and 
local and central governments.
The vital contributions our partners 
provide to the business range from 
providing products, raw materials, 
services and advice through to the 
joint development and co-marketing of 
products to the life science community.
How we engage 
with them
We engage with our partners through 
relationship meetings with key partners 
and suppliers, through attending and 
running conferences and seminars 
on key issues, and through the use of 
questionnaires and due diligence.
We also engage through market 
insight and technologies, for example 
we have been able to propose and 
develop content for some of our 
partners’ proteomics platforms.
Our industry partners receive access 
to our products and technologies, 
supporting the development of 
antibodies and immunoassays that 
they are able to take to market for 
diagnostic and therapeutic use.
The Board receives updates on 
performance at each Board meeting.
Our Partners
What has mattered to 
them this year and 
our response
Our partners have looked to Abcam’s 
ability to support them as they develop 
and launch new products including 
clinical diagnostics to market. Our 
partners also expect a high-quality 
product to develop consistent 
solutions from early research to clinical 
diagnostic solutions.
Through the custom development 
of new antibodies and the out-
licensing of our existing antibodies to 
biopharmaceutical and diagnostic 
companies, we have extended the 
commercial potential of our products 
into these markets.
Our commitment to quality reassures 
our partners that they will achieve 
content portability from early research 
to clinical diagnostic solutions.
We have also continued working with 
our proteomic platform partners to co-
market and co-develop programmes 
that enable easy translation of Abcam 
content from early discovery through to 
clinical diagnostics.
We continue to align our product 
development pipeline to the needs 
of our partners to ensure they get the 
earliest access to our content portfolio 
and new products for testing and 
validation, to help drive new disease 
research forward. Our industry leading 
innovation platform, informed by data 
analytics, research area specialists 
and our strong customer relationships, 
enables us to anticipate which tools 
researchers will need in the future and 
align our innovation efforts with our 
customers’ research priorities.
Our partners are increasingly interested 
in the sustainability of our supply chain 
and gaining access to sustainability 
data. We have increased our disclosure 
and reporting in this area as a 
result, through the publication of our 
Impact Report and our partnership 
with EcoVadis.

Our section 172 statement continued
Who they are and why 
they matter to us?
Those who live and work in areas where 
we operate – and society as a whole.
We need to develop positive local 
relationships and understand local 
people’s needs in order to attract talent 
and deliver our goals.
How we engage 
with them
The Board receives updates on our 
sustainability and ESG initiatives and 
has appointed the CEO as the Board 
member responsible for ESG matters. 
It receives updates from the CEO at 
each Board meeting.
We promote access to STEM careers 
through our partnership with 
In2Science and other initiatives.
Our Communities
What has mattered to 
them this year and 
our response
We believe that the scientific community 
can go further, faster, when we go there 
together. We recognise that scientific 
breakthroughs are the product of 
whole teams and communities working 
together and we understand our role in 
generating a positive impact on science 
and ultimately health and wellbeing. 
Our communities also want us to act 
responsibly, reduce environmental 
impact and help them thrive.
Engagement from our communities 
on diversity and inclusion continues to 
increase, in particular on how we can 
create opportunities in STEM for those 
that are often overlooked.
Our ‘Employee Resource Groups’ 
which are employee-led, leader-
sponsored forums, educate on and 
champion the topics of gender, race, 
sexual orientation, mental health, 
social mobility, family networks and 
diverse abilities. They have organised 
partner events and speakers 
from the community, as have our 
charity committees.
We partner with local charities and 
agencies, which allows employees to 
see first-hand how we have impact in 
our communities, and we’ve continued 
to strengthen our partnerships in 
promoting STEM careers, adapting 
global onsite events to a digital format. 
Apprenticeships, work experience, 
career talks and insight days have all 
been delivered with In2Science, Access 
Accountancy, Form the Future and 
Cambridge Launchpad & selected 
education establishments around 
the globe.
We’ve continued our outreach into 
community schools in and around 
Boston and have maintained our 
Co‑ops and internship programmes 
both in the US and UK.
We are in our fifth year partnering with 
In2Science in the UK and our third year 
of funding STEM education for Henrietta 
Lacks’ great great grandchildren, 
through The Henrietta Lacks Foundation. 
We have also donated to the Actors’ 
Touring Company’s community 
workshops, in which they discuss 
Henrietta Lacks’ legacy. The workshops 
are being held to complement their 
tour of Family Tree, a play based on the 
life of Henrietta Lacks.
Our environmental impact is low but 
we continue to make incremental 
improvements. We offer incentives 
for combined deliveries to save on 
carbon emissions and use EcoVadis 
to assess our suppliers on things that 
our communities care a lot about 
(sustainability), so that we can work with 
them to improve their (and our) impact.

The Board is committed to maintaining 
an appropriate level of communication 
with shareholders. The Executive 
Directors and Vice President of Investor 
Relations are available throughout 
the year for investor meetings, and 
work with advisors to give investors 
the opportunity to engage with 
management at a range of forums, the 
most important being the year end and 
interim results presentations.
During the year, we undertook 
consultations with our major 
shareholders with regards to the 
cancellation of the trading of our 
shares on AIM, moving to a sole 
Nasdaq listing.
In May 2022 we published our second 
sustainability publication ‘Our Impact 
2021’ which builds on the Group’s 
sustainability framework following a 
completion of a review to understand 
our impact and prioritise areas of 
action. Our ESG Sponsor also met with 
investors and analysts.
Our website (corporate.abcam.

announcements, financial results and

Description
Total constant currency revenue growth 
of our in-house products published. 
Includes sales from Custom Products 
and Licencing and BioVision following 
the acquisition in October 2021
There are approximately 46,000 in‑house 
products published on our catalogue.
Transactional (often referred to as 
‘touchpoint’) Net Promoter Score (tNPS) 
is an industry standard benchmark 
used to gauge the loyalty of our 
customer relationships based on their 
interactions with us.
Why this metric 
is important
Innovating new, high-quality products 
and growing our in-house product 
portfolio is fundamental to our long-
term growth strategy.
Allows us to monitor customer 
satisfaction on a timely basis, helping to 
determine the likelihood of consumers 
recommending Abcam to a colleague.
How we performed
Growth includes BioVision and 
was negatively impacted by the 
implementation of Oracle Cloud ERP 
system and COVID-19 restrictions in 
China.
The 12-month tNPS score was negatively 
impacted by the implementation of a 
new Oracle Cloud ERP system.

2021: 72.2%
Description
Total revenue growth of the business on 
a constant exchange rate basis (CER). 
CER is achieved by applying the prior 
year’s actual exchange rates to the 
current year’s results.
Adjusted gross margin is calculated by 
dividing total gross profit achieved by 
total sales, before fair value adjustments 
on inventory relating to the BioVision 
acquisition.
Why this metric 
is important
Total revenue growth is a key metric for 
monitoring the Group’s performance 
and ability to drive growth.
Calculating growth on a CER basis 
allows management to identify the 
relative year-on-year performance 
by removing the impact of currency 
movements which are outside of 
management’s control.
Gross margin is a key metric for 
monitoring the Group’s earnings quality 
and potential.
How we performed
Total CER revenue growth includes the 
impact of BioVision and was negatively 
impacted by the implementation of 
the new Oracle Cloud ERP system and 
COVID-19 in China.
Gross margin was favourably impacted 
by increased sales of our in‑house 
portfolio and the inclusion of BioVision.

Description
Operating Profit based on the related 
IFRS measure but excluding adjusting 
items (see note 7 of the consolidated 
financial statements for more 
information).
Return on Capital Employed (ROCE) 
is calculated by dividing adjusted 
operating profit by total capital 
employed at the end of the period.
Capital employed is calculated 
by subtracting the Group’s current 
liabilities from its total assets.
Why this metric 
is important
The Board considers this measurement 
of profitability a viable alternative to 
underlying profit. It represents a key 
metric of overall business profitability.
The Board believes that ROCE is a key 
tool in measuring the Group’s financial 
efficiency and ability to create future 
growth in value.
The Group attempts to maintain ROCE 
at a level well above the Group’s 
estimated cost of capital.
How we performed
Adjusted operating profit increased 26% 
and resulted in an adjusted operating 
margin expansion of 21.1% from 19.2% 
in 2021
Return on capital employed improved 
as profitability improved and the capital 
employed by the business remained 
relatively stable compared with the

Description
Free cash flow comprises net cash 
generated from operating activities less 
net capital expenditure and transfer 
of cash from/(to) escrow in respect of 
future capital expenditure.
Adjusted diluted earnings per share 
(EPS) is calculated by dividing the 
Group’s profit after tax, after adjusting 
items, by the weighted average number 
of ordinary shares in issue, including 
those shares that may be awarded 
under future share option and awards.
Why this metric 
is important
The Board considers this measurement 
important for providing an indication 
of the amount of cash available for 
discretionary growth investment after 
removing capital-related items.
The Board considers this measurement 
an important indicator of the underlying 
profits generated for shareholders.

I am pleased to present 
the Corporate Governance 
Report for the 12 months 
ended 31 December 2022, 
which includes details 
about the Board and 
our individual roles and 
responsibilities and a 
summary of the activities 
of the Board. The Chair of 
each Board Committee 
also discusses the activities 
of that Committee during 
the past year to illustrate 
how we have discharged 
our responsibilities to 
all stakeholders during 
that time.
Abcam’s commitment to Corporate Governance
The Board believes that robust corporate governance is vital to 
maintaining the long-term sustainable performance and growth 
of our business. The Board is responsible for overseeing Abcam’s 
corporate governance measures and you can find further detail 
on Abcam’s approach to corporate governance in the following 
sections of this Governance report, with additional information 
contained in the Strategic report:
Board leadership and company purpose – pages 33 to 36;
Division of responsibilities – pages 34 and 35;
Composition, succession and evaluation – pages 37 and 38;
Audit, risk and internal control – pages 39 to 43;
Remuneration – pages 44 to 59.
Section 172
The Board, advised by the Company Secretary, is mindful of its duties 
under section 172(1)(a) to (f) of the Companies Act 2006 when 
considering any decisions and the impact those decisions may 
have upon all stakeholders. Abcam’s principal stakeholders and 
the impact we have upon them, including details of how we have 
engaged with our employees, is discussed at pages 20 to 59.
Board changes during FY22
Luba Greenwood joined the Board as a Non-Executive Director 
on 12 September 2022. Luba’s experiences focus on business 
development and strategy, and she has held a number of senior 
leadership and board positions in the healthcare industry.
What the Board has focused on in the last 12 months
On 17 October 2022, following a review by the Board of options 
to increase share liquidity and extensive consultation with 
shareholders, the Company announced that it intended to 
cancel the admission of its Ordinary Shares to trading on AIM 
and at 7.00 a.m. (London time) on 14 December 2022 the 
Company’s ordinary shares were cancelled from trading on AIM. 
The Board anticipates that maintaining a sole listing of ADSs 
on Nasdaq will further enhance the liquidity of trading in the 
Company’s securities by combining on Nasdaq the volume of 
transactions from both Nasdaq and AIM.
Abcam concluded the third year of its five-year growth plan by 
further building capabilities to drive long term and profitable 
growth, including the opening of a new Singapore business hub 
and installation of a new Oracle Cloud ERP system. The Board 
remain confident of the Company’s ability to meet its 2024 goals 
and this year we will begin to formulate our strategy for the next 
phase of Abcam’s growth beyond 2024.

Governance structure
Board
The Board has established a corporate governance structure 
with clearly defined responsibilities and accountabilities. The 
structure is designed to safeguard and enhance the long-term 
sustainable success of Abcam, creating value and benefit for 
our shareholders and other stakeholders.
Responsible for the long-term success of the Group, it 
sets strategy and oversees implementation, ensuring only 
acceptable risks are taken. It provides leadership and direction 
and is also responsible for corporate governance and the overall 
financial performance of the Group. The Chairman encourages 
rigorous debate at Board meetings on how Abcam is meeting its 
agreed goals and objectives, and he ensures that the Directors 
receive accurate, timely and clear information.
Matters reserved for the Board
To retain control of key decisions, the Board has identified certain 
reserved matters for its approval. Other matters, responsibilities 
and authorities are delegated to Board Committees. The 
schedule of matters reserved for the Board can be found, along 
with the terms of reference for each of its Committees, on the 
Company’s investor relations website at corporate.abcam.com.
Board meetings, information and support
The Board aims to meet in person six times during the year 
with further scheduled telephone conferences to approve the 
annual and interim accounts. In addition, ad hoc meetings may 
be called to discuss urgent matters arising during the course 
of the year. One such ad hoc Board meeting, two ad hoc Audit 
and Risk Committee meetings and two ad hoc Remuneration 
Committee meetings were called in the 12 months ended 
31 December 2022. Following the developments in working 
practices that occurred in response to the COVID-19 pandemic, 
the Board has continued to meet through a combination of 
in-person attendance and video conferences. This has allowed 
Board meetings to continue to be conducted in largely the 
same manner as prior to imposition of social distancing 
restrictions, save that Board members are no longer all present 
in the same location. The Chair expects Non-Executive Directors 
to provide sufficient commitment to the Company for advance 
preparation and attendance at Board and Committee meetings, 
together with ad hoc availability at other times.

Our percentage of women on the Board and on the executive 
leadership team increased to 40% as at 31 December 2022 
(36% as at 31 December 2021), and we continue to seek 
to increase the pipeline of women into both the Board and 
senior management.
Director independence
The Board considers all Non-Executive Directors to be 
independent within the meaning of the Nasdaq Rules. The Board 
considers that the Non-Executive Directors each demonstrate 
an appropriate degree of independence in character 
and judgement and are free from any business or other 
relationship which could materially interfere with the exercise of 
their judgement.
In determining the independence of the Non-Executive Directors, 
the Board specifically considers the beneficial interests of such 
Directors in the share capital of the Company. Those interests 
are set out on page 54 and do not in the opinion of the Board 
detract from their independent status.
In accordance with its procedures, all Directors are required to 
notify the Board of any conflicts of interest and a register of such 
interests is maintained by the Company Secretary and formally 
reviewed at Board meetings. Any planned changes to their 
interests, including directorships outside the Group, are notified 
to the Board. In addition, all directors are required to confirm 
annually all relationships that they have that may represent a 
conflict of interest.
The independent Non-Executive Directors declared no 
relationships in the period which were considered a conflict 
with Abcam’s business and therefore nothing was deemed to 
impact their independence.

during the year ended 31 December 2022 on page 22. The 
Board considers the measures taken on employee engagement 
to be effective because they create and foster open and honest 
dialogue between employees and the Board and maintain the 
Board’s awareness of employee sentiment, which in turn informs 
the Board’s decision making.
Shareholder engagement
The Board is committed to maintaining an open and 
constructive dialogue with shareholders to ensure there is a 
common understanding of the strategic objectives, governance 
and performance of the Company. Further detail of how we 
have engaged with shareholders throughout the year ended 
31 December 2022 can be found on page 25.

Key responsibilities of the Committee
The Committee is responsible for reviewing Board composition 
and balance, considering the skills and capabilities required 
for each new Board appointment, leading the process for 
the Board in relation to new appointments and reviewing 
succession planning for the Board and senior leadership. 
The Committee continues to perform this with the utmost 
professionalism and diligence.
Board changes in the year
We have continued to review potential additions to the Board to 
ensure strong succession and the right mix of experience and 
skills. This year we have made one addition to the Board using 
the services of an executive search firm, with the appointment of 
Luba Greenwood on 12 September 2022.
Luba’s experience focuses on business development and 
strategy. She is a veteran biotech, pharmaceutical, tech, and 
life sciences investor and company builder. Luba has held 
a number of senior leadership and board positions in the 
healthcare industry. Currently, she serves as the managing 
partner of the Dana Farber Cancer Institute Venture Fund, Binney 
Street Capital (BSC), which she has built and launched. Luba is 
also the CEO of Kojin Therapeutics, a BSC portfolio company. Her 
previous experience includes increasing levels of responsibility at 
Google Life Sciences, Verily and F. Hoffman-La Roche.
Luba has extensive board experience, and currently serves 
on the board of directors of the following private institutions: 
MassBio, BenchSci, and In8Bio, Inc.
I have worked with the Executive Directors to support Luba’s 
onboarding with training, including our director onboarding 
training run by the Company Secretary, meeting the Executive 
leadership Team and also site visits. I am delighted to have 
Luba’s insight and experience as a member of the Board.
Board diversity and appointments procedure
Abcam recognises and embraces the benefits of having a 
diverse Board, and sees diversity at Board level as an essential 
element in maintaining a competitive advantage and the 
Company’s long-term sustainable success.
Board composition is central to the effective leadership of 
the Group and therefore prior to commencing any search 
for prospective Board members, the Committee draws up 
a specification, reflecting on the Board’s current balance of 
skills and experience and those that would be conducive to 
the delivery of the Company’s strategy. Selection for Board 
appointments is made on merit against this specification.

Gender diversity
Following the Board changes in the year, female representation 
on the Board stands at 44%. Abcam continues to see the 
development of female executive talent as an important area.
Activity in the year
We have been pleased to see the depth of succession building 
for the Executive Leadership Team and that Abcam has 
continued to be able to develop and grow talent internally, as 
well as attract great candidates from the external market.
This year we have refreshed our Board mentoring programme 
where members of our Executive Leadership Team are mentored 
by our Non-Executive Directors. This is positive at supporting 
our senior leaders with experience and insight to drive the 
performance of the business.
We have also been able to undertake site visits where those 
have been practical. This has included holding Board meetings 
in both the UK and US. This has enabled to Board to meet 
a broad range of employees and also to understand more 
about the business.
In the course of 2022 we have undertaken a number of training 
initiatives based on the Board assessment undertaken in 2021. 
This has included offering training to support the transition to 
NASDAQ listing, context on ESG reporting and updates on the 
life sciences market.
Priorities for 2023
The Committee will continue to focus on succession planning, 
particularly for Executive Leadership Team positions, as well as 
supporting the mentoring of the senior team. I will also continue 
to support the development of the Board in delivering the 
training identified from the Board Evaluation process. With the 
move to NASDAQ listing I have decided to postpone the Board 
Evaluation until 2023 where we can consider US requirements.

Introduction
As Chairman of the Committee, I am pleased to present the 
report of the Audit and Risk Committee for the 12 months ended 
31 December 2022.
This report sets out the work of the Committee over the 
12 months and offers insight into how the Committee has 
discharged the responsibilities delegated to it by the Board and 
the key areas of focus has considered in doing so.
In meeting its responsibilities, the Committee continues to 
consider the requirements of good corporate governance and 
the FRC Guidance on Audit Committees and the applicable 
requirements of the SEC and NASDAQ in relation to the listing 
of Abcam’s securities on NASDAQ. The Committee’s Terms of 
Reference are available on corporate.abcam.com.
The Committee works to a structured programme of activities 
which is focused on the Group’s reporting cycle, principal risks 
and risk appetite and keeps in mind a forward looking strategic 
agenda. These activities are supplemented throughout the year 
as key matters arise.
The Committee’s primary focus has been:
	–
monitoring the integrity of the Company’s external reporting 
and accounts. Of particular interest this year has been the 
preparation work for moving to quarterly reporting under US 
GAAP and in USD;
	–
appraising a formal update to the Group’s principal risks and 
risk appetite statements;
	–
review of the growing Internal Audit function and its outputs;
	–
assessing the progress made the second year of the 
Company’s SOX programme against the material 
weaknesses as reported by management in 2021;
	–
overseeing the judgements and estimates made in 
the accounting valuations of Biovision 12 months after 
acquisition, in particular in respect of intangible assets 
acquired; and
	–
Understanding the risks and mitigating strategies as a result 
of the Oracle Cloud ERP deployment in the second half 
of 2022.
In exercising its duties, the Committee undertakes a crucial role 
in providing effective governance over the Group’s financial 
reporting and internal control procedures thereby ensuring that 
shareholders’ interests are protected and the Company’s long 
term strategy is supported.
Committee governance
Membership
The Committee continues to be comprised exclusively of 
independent Non-Executive Directors.
Independence and experience
The Board has confirmed that it is satisfied that the Committee 
members provide an appropriate depth of financial, risk 
management and commercial experience across different 
industries including life sciences and in listed companies. The 
Committee acts independently of management. The Board 
has also confirmed that it is satisfied that Giles Kerr being 
a chartered accountant and having held other finance 
appointments meets the requirement for recent and relevant 
financial experience.
Meetings
The Chief Financial Officer, Vice President Global Finance, 
Company Secretary (acting as secretary to the Committee), 
Head of internal audit, other members of senior management 
and representatives of the Company’s external auditor 
(PricewaterhouseCoopers LLP (PwC)) attended by invitation.
Audit and Risk Committee

Abcam plc Annual Report and Accounts 2022

Audit and Risk Committee continued
Representatives of the Group’s external auditor meet with the 
Committee at least once a year without Executive Directors or 
management being present.
External advice
The Board makes funds available to the Committee to enable it 
to take independent legal, accounting or other advice when the 
Committee believes it necessary to do so.
Key Committee activities during 2022
Financial reporting
	–
Considering matters of accounting significance, 
estimation and judgement including those in respect 
of the Biovision acquisition;
	–
Monitoring the integrity of the Annual Report and 
Accounts, the Interim Statement, Form 20-F and any 
formal announcements or regulatory filings relating 
to financial performance, to ensure clarity and 
completeness of disclosures, including those relating to 
alternative performance measures (including adjusted 
performance measures);
	–
Receiving presentations from management on all financial 
reporting matters Including preparation for the move to 
reporting quarterly under US GAAP and In USD;
	–
Reviewing the results and conclusions of work performed 
by the external auditor;
	–
Reviewing the basis for the going concern statement in 
light of financial plans and reasonably possible scenarios 
especially considering the continued impacts on the 
business in China of COVID-19;
	–
Reviewing the longer-term viability statement (LTVS) including 
appraising the Board’s approach and use of its five-year plan 
on which the LTVS is based, linkage to strategy, principal risks, 
together with related scenario stress analysis; and
	–
Considering if the Annual Report and Accounts, when 
taken as a whole, is fair, balanced and understandable.
Fair, balanced and understandable
The Annual Report and Accounts continues to focus strongly 
on key strategic messages and the Committee has had due 
attention to this emphasis and balance where it may affect 
disclosures elsewhere in the Annual Report and Accounts. 
In ensuring that the Group’s reporting is fair, balanced and 
understandable, the Committee reviewed the classification of 
items between adjusted and reported performance measures 
and the clarity and comprehensiveness of disclosures around 
adjusting items.
In addition, the Committee gave due consideration to the 
integrity and sufficiency of information disclosed in the Annual 
Report and Accounts to ensure that they clearly explain the 
Group’s financial position, performance, business model 
and strategy. An assessment of the narrative reporting was 
also undertaken to ensure consistency with the financial 
statements, including appropriate disclosure of material or 
significant items necessary to aid a reader’s understanding 
and appropriate balance of reported and adjusted 
performance measures.
Risk management, internal control and SOX
The Committee receives updates on risk, internal control 
and SOX matters at each meeting. This regular monitoring 
allows timely identification of issues and formal tracking of 
remediation plans. The main areas of assessment were:
	–
Considering the formal review undertaken in the year 
of the Groups’ principal risks, emerging risks and risk 
appetite statements and recommending to the Board 
the adoption thereon;
	–
Monitoring continual improvements in risk management 
including reviewing actions to mitigate risk and 
challenging the assessment of risk mitigations in line with 
risk appetite;
	–
Reviewed the internal audit plan for the current and 
forthcoming year ensuring alignment with key risks;
	–
Reviewing the effectiveness and integrity of the internal 
controls framework with particular reference to the 
requirements of SOX this year. The Committee has reviewed 
progress against the material weaknesses identified in 2021 
under the requirements of SOX as reported by management 
and engaged with the associated remediation plan;
	–
Monitoring progress on the implementation and project 
governance of transformational projects; and
	–
Receiving updates on continual strengthening of cyber 
security measures.
Compliance
The Committee reviews and considers the operation of the 
Group’s compliance initiatives. These include the employee 
Code of Conduct ‘How we do things at Abcam’, a global 
whistleblowing hotline and portal, an anonymous messaging 
inbox for messaging the CEO, and compulsory online training 
for anti-bribery and corruption and GDPR.
During the year the Committee received updates from 
management on GDPR, the compliance requirements 
of the Sarbannes-Oxley Act and an annual governance 
‘health check’.

Financial statements
Matters of significant judgement
The Committee received reports from management setting out the significant accounting and financial reporting matters and 
judgements in respect of the financial statements as well as how these matters were addressed. The following sets out the main areas 
of judgement considered by the Committee. For each area, the Committee was satisfied with the accounting and disclosures in the 
Annual Report and Accounts and noted the work performed by the external auditor.
Matters of accounting significance and judgement
Committee’s review and conclusions
Costing of internally developed technology capitalised 
within intangible assets
Internal costs are capitalised as internally developed 
technology within intangible assets which is used to generate 
antibodies and kits.
The point at which such internal costs are included and 
capitalised as well as their magnitude (where the amount 
capitalised comprises mainly of attributable salary costs 
and consumables used in the manufacture process) is a 
key area of judgement.

The Committee discussed and challenged management’s 
review and also considered the report from the auditor on the 
results of its testing.
The Committee was satisfied that severe but plausible downside 
scenarios were appropriate whilst still supporting the Group’s 
longer term viability and its going concern statement.
Classification of costs associated with system 
process improvements
FY22 was the final year of the complex Oracle Cloud ERP 
transformation with numerous phases across multiple functions 
necessary to secure the Group’s longer- term growth ambitions. 
The work involved both internal and external costs and 
judgement is required both in respect of whether the amounts 
qualify for capitalisation and whether amounts which are 
expensed are incremental given that these are separately 
disclosed as such.
Primary oversight of this important programme at Board level 
has been maintained.

In line with last year, the Committee received reports from 
management and the external auditor regarding the 
classification of amounts expensed versus those capitalised 
and remained satisfied with the treatment.
Detailed aspects of the project evolved throughout the year 
and regular updates were provided at Board level.
Accounting adjustments related to the BioVision acquisition
The Group purchased BioVision in October 2021. As set out in 
note 29 to the consolidated financial statements, the Group 
has taken the opportunity to revise valuation estimates in the 
following 12 months as new information became available. 
The Committee received and reviewed reports from 
management and, where appropriate, challenged these 
judgements and estimates. 
Carrying Value of acquired intangibles
Throughout the year, management assesses for indicators 
of impairment and reports to the Committee. Specifically 
management reviewed assets relating to the Firefly Bioworks 
multiplex and assay technology. At the end of June 2022 
these assets were classified as held for sale as management 
had begun a sale process supported by a third party. During 
the second half of the year, when no sale was possible, 
management took the decision to close the business and as 
such impair all the assets. See note 9.
The Committee received and reviewed reports from 
management and, where appropriate, challenged the 
assumptions taken and the conclusion reached.
Provision for doubtful debts
The implementation of if the new ERP system has disrupted 
invoicing and cash collection to the extent that the trade 
debtors balance is higher at the end of the year than normal. 
As a result, it was deemed prudent to increase the provision 
from 2.3%, year ended 31st December 2021, to 3.4% for the year 
ended 31st December 2022
The committee reviewed managements’ recommended 
increase and the plan to return debtors to more normal levels. 
The committee concluded both were appropriate.

Audit and Risk Committee continued
Matters of significant judgement continued
Share based payments
With material new share based schemes (PGIP/AGP) in 
operation, the Group is required to assess the annual charge 
based on the probability of payout. Papers were presented that 
considered the likelihood of achieving revenue targets and the 
ROCE underpin. Internal and external drivers were considered 
in deriving the charge.
The committee reviewed the assessment and concluded that 
the charge was appropriate.
Going concern statement
Assumptions underlying the going concern statement made 
on page 61 are based upon the Group’s budget and five-
year financial and operating plans. These include appropriate 
scenario analysis and take into account the Group’s principal 
risks as well as the current economic disruption following 
Covid-19 and the ongoing war in Ukraine.
The Committee, in conjunction with the Board, reviewed the 
plans and scenarios and was satisfied that in respect of the 
going concern statement, a period of five years was suitable 
and concurred with management’s conclusions that the going 
concern statement is appropriate.
The Committee was satisfied that severe but plausible downside 
scenarios were appropriate whilst still supporting the Group’s 
longer term viability and its going concern statement.
Internal audit
The internal audit function provides independent and 
objective assurance over the design and operating 
effectiveness of the system of internal control though a risk-
focused approach. The function reports into the Committee and 
administratively to the CFO.
This is the second full year of the in-house internal audit function. 
KPMG is retained to conduct specific IT audits and CFGI to 
perform IT SOX testing.
Prior to the start of each financial year, the Committee reviews 
and approves the annual internal audit plan, a further 
review occurs during the year to take account of any need 
to refocus. The programme was refocused during the year to 
allow appropriate attention on the second year of the SOX 
programme with a particular focus on the material weaknesses 
as reported by management in FY21.
The Committee is satisfied that the internal audit programme 
remains risk focused, is functioning satisfactorily across the 
Group, that management is open to reviews and takes action on 
recommendations on a timely basis.
The Committee continues to review how the internal audit 
function will need to evolve in future years.
External auditor
Independence and objectivity
Both the Board and the external auditor (PwC) have safeguards 
in place to protect the independence and objectivity of 
the external auditor. The Committee receives details of any 
relationships between the Company and PwC that may have 
a bearing on their independence. These were reviewed by 
the Committee during the year and remain satisfactory. In 
accordance with International Standards on Auditing (UK), PwC 
formally confirmed to the Board its independence as auditor of 
the Company.
Non-audit fees
Any non-audit services require approval by the Committee and 
the amounts are set out in note 6 to the consolidated financial 
statements. Non-audit fees comprised fees in relation to interim 
reviews and the Group’s US filings.
Non-audit fees amounts to £667,000 (2020/21: £1,379,000) 
compared to £817,000 of audit fees (2020/21: £1,084,000). Audit 
fees for period to 31 December 2022 have increased due to the 
growth of Abcam and industry wide inflation in audit fees driven 
by increasingly regulatory pressure. The non-audit fees include 
assurance work in relation to Sarbanes-Oxley.

Auditor appointment and tendering
PwC has served as Abcam’s external auditor since September 
2013, when a full tender process was undertaken. The current 
audit partner, Sam Taylor, has served for four and a half years 
and is standing down at the end of the FY22 reporting year. 
Paul Norbury will take over in 2023. The Committee considers 
Paul an excellent candidate noting his life sciences experience 
combined with his US GAAP, PCAOB and SOX skills.
PwC’s objectivity, independence and performance are 
considered to remain strong and the Committee has 
recommended to the Board that PwC be re-appointed as 
external auditor for the 2023 financial year, subject to approval 
at the AGM.
Auditor effectiveness
The Committee undertakes an annual assessment of 
the effectiveness of the external auditor. This assessment 
incorporates the views of management in addition to the Non-
Executive Directors to facilitate continued improvement in the 
external audit process.
The assessment considered:
	–
Audit risk identification whereby this is a key factor in the 
delivery of a thorough, robust and efficient global audit in 
accordance with pre-set timescales. These risks remained 
broadly consistent with the prior financial year, but with 
additional focus on acquisitions given the activity in this area 
during the year;
	–
Provision of accurate, robust and perceptive advice on key 
accounting and audit judgements, technical issues and 
best practice;
	–
The level of professionalism and technical expertise 
consistently demonstrated and maintenance of continuity 
within the core audit team; and
	–
Strict adherence to independence policies and other 
regulatory requirements.
The Committee concluded that the above factors had 
been met, and that it continued to be satisfied with PwC’s 
performance and effectiveness.
Conclusions
The Committee’s oversight of financial reporting, external and 
internal audit, risk and the development of the SOX control 
environments have been areas of significant focus.
These are likely to remain so for the 2023 financial year as the 
Group grows and develops in line with its strategy.
The Committee remains focused on ensuring that finance and 
risk capability is enhanced appropriately to manage in an 
increasingly complex business and an increasingly regulated 
environment.
I am confident that the Committee has the necessary skills and 
experience to continue to meet the challenges ahead.

On behalf of the Board, I am pleased to present the Directors’ 
Remuneration Report for 2022
As I mentioned in my first report as Remuneration Committee 
chair last year, I have long been an admirer of Abcam’s 
commitment to its people and track record of aligning 
interests across the Company with those of our shareholders. 
This philosophy underpins our approach to reward: from our 
global multi-award-winning share plan, AbShare, which vested 
in 2021 to make over 90% of our employees shareholders, to 
the introduction of the Abcam Growth Plan (‘AGP’) and the 
extension to senior leaders of the Profitable Growth Incentive 
Plan (‘PGIP’) in 2022. Through these and a wide range of other 
people-centric initiatives, Abcam has continued to position 
itself as a great place to work, with employee engagement well 
above external benchmarks.
In this report, I am pleased to share an overview of the 
Committee’s key decisions over the year to 31 December 2022 
and how we are aligning our remuneration structure even 
more closely to the delivery of our strategy through our new 
Remuneration Policy approved by shareholders at the General 
Meeting in July 2021 and approved again at the AGM in May 
2022 (‘Policy’).
Our Remuneration Policy
Abcam’s new Remuneration Policy (‘Policy’) and Profitable Growth 
Incentive Plan (‘PGIP’) were both approved at the July 2021 
General Meeting and received a further positive vote at the May 
2022 Annual General Meeting which was required due to technical 
requirements of the Companies Act 2006. I would like to thank our 
shareholders for their engagement over the course of 2022.
The Remuneration Committee continues to believe that the 
remuneration package offered to Executive Directors is fair whilst 
remaining competitive amongst our peers, including in the US as 
the Americas is a key market for talent (>25% of our headcount) 
and our business (45% of our revenue). The Committee is 
committed to ensuring the Company’s leadership is motivated 
to deliver long-term sustainable growth through the successful 
implementation of the Five-Year Growth Plan to 2024. As such, 
the Policy and PGIP align all senior leaders to the delivery of 
Abcam’s strategic goals, with a continued focus on profitable 
growth and long-term sustainable value creation.
Remuneration in wider context
Alongside decisions made on executive remuneration, the 
Committee provides oversight of the remuneration of the 
Executive Leadership Team, broader workforce trends and inputs 
into the formulation of reward programmes across our global 
workforce. This includes the strategic review and approval of our 
incentive plans and their performance criteria to ensure each 
plan is aligned to the interests of our stakeholders and the long-
term success of the Company.
Remuneration Committee

Abcam plc Annual Report and Accounts 2022

Strategic Report
Corporate governance
Financial statements
An example of the Committee’s role in this regard was in the 
design and approval of our all employee share plan, the 
Abcam Growth Plan, which ensures that all employees globally 
are incentivised and meaningfully rewarded for delivering for 
customers and Abcam’s strategic goals to 2024. The first awards 
under this plan will vest in April this year and further annual 
awards will be made to employees. This programme builds on 
the success of AbShare with a further meaningful offer of equity 
participation for our people. Participants in the PGIP are not 
eligible to participate in the Abcam Growth Plan. There has also 
been a further award of the PGIP to senior managers below 
the executive leadership team where there are now a total of 
around 150 leaders that participate in the plan. The Committee 
also completed a review of the Company’s global mobility 
policies to support internal talent mobility for our people among 
jobs, projects, and geographies.
As a result of these initiatives, employee engagement 
scores on the topic of reward have been maintained over 
the year to 31 December 2022 and remains in the top 25% 
of comparator companies.
When making decisions on executive remuneration and setting 
our Directors’ Remuneration Policy, the Committee does so in 
consideration of our global workforce to ensure our total reward 
offer supports business priorities and is aligned to stakeholder 
interests, whilst supporting our culture and values. Further details 
on how the decisions made for Executive Directors compare to 
the wider workforce are provided on page 56.
2022 remuneration outcomes
The Committee always seeks to ensure that the remuneration 
of our Executive Directors reflects the underlying performance 
of the business, as summarised on pages 1 to 30 of the Annual 
Report. When approving outcomes, we therefore considered 
performance against our financial and strategic targets along 
with wider business and individual performance and believe 
that the decisions outlined below fairly reflect 2022 performance.
Annual Bonus Plan (ABP)
Annual bonus outcomes were considered in the context of 
financial, strategic, environmental, social and governance (ESG) 
and personal performance and the performance out-turn was 
as follows:
1 January to 31 December 2022 – out-turns were 12.5% 
(out of 50%) and 0% (out of 33%) of the maximum award for 
financial and strategic measures, respectively, reflecting the 
stretching targets and the impact of the go-live transition of the 
core Oracle Cloud ERP system over the second half of 2022, 
despite strong underlying performance. In combination with 
performance which exceeded targets under personal objectives 
and ESG targets the ABP will pay 25.3% of the maximum for the 
CEO and 27.0% of the maximum for the CFO.
30% of the earned bonus for the Executive Directors will be 
deferred into shares for two years. Further details regarding the 
achievement against each performance target are set out on 
page 50.
Long Term Incentive Plan (LTIP)
The 2019 awards were intended to reward and incentivise senior 
leaders over the three-year period from 1 July 2019 to 30 June 
2022. Under the 2019 LTIP, Alan Hirzel and Michael Baldock 
received two awards: (1) LTIP A, measured against Earnings Per 
Share (EPS) and Strategic KPIs; and (2) LTIP B, measured against 
Revenue Growth.
1.	 LTIP A – overall vesting of 21.6% of maximum award. 
Recombinant antibody revenue growth performance was 
above the maximum targets set and customer engagement 
(tNPS) performance above the threshold target. EPS 
performance was below the threshold target set due to the 
significant strategic investments made by the Company over 
the performance period.
2.	 LTIP B – overall vesting of 100% of maximum based on 
performance that was above the maximum target with 
revenues growing at a compound rate of 11.5% over the 
performance period.
No adjustments have been made to out-turns over the 
performance period. The EPS out-turn under LTIP A reflects 
the evolution of Abcam’s strategy and significant strategic 
investments focused on growth since the awards were granted.
The Committee considered that the formulaic out-turns for 
both the annual bonus and LTIP were appropriate in the 
context of wider business performance and reflective of the 
broader stakeholder experience. Further details regarding the 
achievement against the performance targets are on page 51.
Implementation for 2023
The CEO and the CFO did not receive a salary increase during 
2022, and hence continued on the same salary since 1 July 
2020. Following a comprehensive review by the Committee, 
the base salary for Alan Hirzel has been increased by 4% from 
£629,760 to £654,950 effective 1 January 2023. This compares 
to the UK average workforce increase of 10% over the period 
since his last salary increase in 1 July 2020. Michael Baldock 
relocated to the US effective from 1 January 2023, with 
support in accordance with the Company’s global mobility 
framework. His US salary was set relative to US based peers at 
a level of $610,000. The Committee believes that this salary is 
reflective of his exceptional personal performance since his 
appointment, the scope of his role (finance, legal and corporate 
development) and the competitiveness of the US market for 
senior finance talent.

Remuneration Committee continued
Both Alan Hirzel and Michael Baldock’s pension entitlement were 
aligned with the wider UK workforce following the reduction in 
pension entitlement for Alan Hirzel to 8% of base salary effective 
1 July 2020. Michael Baldock’s pension entitlement was originally 
aligned to the wider UK workforce from his appointment to end 
2022 while he was employed in the UK, and was maintained at 
this level on his relocation to the US.
The 2023 ABP design will be broadly unchanged from 2022, with 
targets updated in line with the financial plan and outlook for 
2023 in the usual way. The PGIP remains in-flight until 2024 and so 
there will be no new long-term incentives granted to Executive 
Directors during the year.
Policy developments as a result of the change in listing
During 2022 I led a review of our Remuneration Advisors. We 
were able to meet a number of companies through the tender 
process and the committee were pleased to appoint F.W. Cook 
in partnership with FIT Consulting to advise us. Their combination 
of experience and knowledge across the US and UK markets 
will make them a valuable partner to the Committee. With a 
sole listing on NASDAQ, the Company has eliminated certain 
complexities and duplication that comes from administering 
two different listing regimes. Whilst we do not intend to make 
significant changes to our remuneration approach in 2023, the 
Committee is mindful that US market and reporting requirements 
will require a transition process ahead of our next policy review 
in 2024.

Strategically aligned
Our remuneration structure reflects and is aligned with our 
business strategy and culture. Equity ownership is central to our 
approach to remuneration which we believe can drive the right 
long-term behaviour and alignment with stakeholders’ interest 
in the Company’s sustainable long-term profitable growth. To 
further align the interests of Executive Directors with those of 
stakeholders, they are required to build and maintain significant 
shareholdings in Abcam over time, equal to two-times their base 
salaries in value.
We have consistently demonstrated our commitment to 
employee share ownership through AbShare, our previous multi-
award winning share purchase plan, and more recently through 
the implementation of its successor programme, the Abcam 
Growth Plan. In line with our culture & behaviours, both plans are 
centred around dedication through company ownership. They 
are equally audacious and bold in ambition, enabling all of our 
people globally to share meaningfully in Abcam’s success. The 
Executive Directors and other senior leaders on the PGIP are not 
eligible to participate in the Abcam Growth Plan.
Pay for performance
The remuneration of our leaders is structured to promote the 
long-term success of the Company and to reward value creation 
for our stakeholders.
Short-term incentives
Assessment of short-term incentives under the Annual Bonus 
Plan (ABP) is made against a scorecard of performance 
measures built around Abcam’s key financial, strategic and ESG 
priorities for the relevant year. There is a deferral of shares under 
the ABP for Executive Directors and senior managers for a further 
two-year period following the initial year of performance.
Long-term incentives
Awards are linked to Abcam’s long-term profitable growth 
strategy. To further promote equity ownership and long-term 
performance, vesting occurs at the end of three-and-a-half years 
with holding periods applying after the awards vest.
Wellbeing
Flexibility and choice are key to our employee benefits package 
through which we aim to support colleagues financial, physical 
and mental wellbeing. We want to be there for our people when 
it really counts which is why all of our employees globally receive 
company-paid life insurance and offer an above market global 
family leave policy with 18 weeks fully paid maternity leave and 
six weeks fully paid paternity leave.
Market competitive
All elements of our remuneration are reviewed regularly to 
ensure they remain market competitive in order to attract and 
retain talent as well as to avoid excessive overpayment.
Fair pay
We are committed to paying our people fairly, ensuring that all 
our employees are appropriately and fairly rewarded.
Clear, transparent and simple
A key priority is to ensure that all of our employees understand 
how they are rewarded and we believe our remuneration 
structures should be as clear and simple as possible, so that 
everyone can understand how they are remunerated for 
performance.
Compliance and risk
The Committee’s role is to ensure our remuneration structures 
are compliant with the laws and corporate governance 
requirements that apply and risk assessment is a key 
consideration of all remuneration decisions.
Remuneration Principles

Abcam plc Annual Report and Accounts 2022

Executive Directors’ base salaries
The CEO and the CFO did not receive a salary increase 
during 2022, and hence continued at the same salary since 
1 July 2020. In November 2022, the Remuneration Committee 
reviewed the compensation packages of the CEO and the CFO 
against the market data for their roles in the UK and the US, and 
recommended new salary levels effective 1 January 2023. The 
CEO’s salary was increased 4% to £654,950, which compares 
to the UK average workforce increase of 10% over the period 
since his last salary increase in 1 July 2020. Effective 1 January 
2023 Michael relocated to the US and his salary was reviewed 
to $610,000, taking into account his starting salary in USD terms 
when he moved from the US in February 2020. The revised salary 
reflects market terms and conditions and peer benchmarks for 
the new location of his role in the US – an increase of 11% over 
the USD equivalent of his salary at 1 January 2022.

 The appreciation of the USD against GBP over 2022 (based on the balance sheet

above) results in the larger quoted increase compared to 11% (at an exchange 
rate of 1.34 USD/GBP at 31 December 2021).
Annual Bonus Plan
The overall framework under the Annual Bonus Plan (ABP) will be 
as follows.

At the Committee’s discretion, the bonus may be restricted if any 
of the four performance elements (financial, strategic, personal 
or ESG) shows serious underperformance, or if the Committee 
determines that there has been underperformance on the part 
of an Executive Director in their role.
Profitable Growth Incentive Plan (“PGIP”)
The PGIP, approved by shareholders at the General Meeting in 
July 2021, aims to align Abcam’s reward to shareholders and 
incentivise Executive Directors to deliver Abcam’s revenue growth 
ambition by the end of 2024, underpinned by Return on Capital 
Employed (‘ROCE’).
The one-off conditional share awards under the PGIP were 
granted on 14 July 2021 and are subject to a three-and-a-half 
year performance period from 1 July 2021 to 31 December 2024. 
Awards are subject to the delivery of Abcam’s revenue growth 
targets and a Return on Capital Employed (ROCE) underpin.
No further awards will be made to the existing Executive Directors 
over the life of the plan. The Committee does though reserve the 
right to make PGIP awards to any future new Executive Director 
hires during the plan period, albeit that there are no plans to 
recruit or increase the number of Executive Directors at this time.
Further details are set out on from page 53 of the 
Remuneration Report.
Pensions and flexible benefits
The Executive Directors are entitled to contributions from the 
Company into a flexible benefits fund which can be used for 
defined contribution pension plan contributions, a range of 
flexible benefits, or an equivalent cash supplement where their 
pension arrangements are fully funded. They also receive a 
range of core benefits such as life insurance, private medical 
cover and annual health screens. Alan Hirzel’s pension 
contribution is aligned with the wider UK workforce at 8% of base 
salary. Michael Baldock’s pension entitlement was originally 
aligned to the wider UK workforce from his appointment to end 
2022 while he was employed in the UK, and was maintained at 
this level on his relocation to the US.
Non-Executive Directors
During 2016 the Company put in place fee arrangements for 
all Non-Executive Directors where a portion of their fees would 
be delivered as a fixed number of fully paid ordinary shares. 
This structure will continue for 2023 and remain in place until 
2024. The level of fees, and the calibrated notional share 
price for converting a portion of the fee to share awards, is 
reviewed annually.

Annual Bonus Plan (ABP) – targets and performance outcomes
Annual bonus outcomes were considered in the context of financial, strategic, ESG and personal performance over the 12 months

the overall result is appropriate in the context of business performance and reflective of the wider stakeholder experience during the 
period. The Executive Directors’ maximum annual opportunity for the 12 months to 31 December 2022 was 150% of base salary. 30% of 
the earned bonus for the CEO and CFO will be deferred into shares for two years.

2022 single figure for total remuneration for the Chairman and the other Non-Executive Directors (NEDs)
The Company has a philosophy of share ownership which is extended to the Chairman and NEDs by delivering one third of their fees 
as Abcam shares. Shares for NEDs are awarded at the beginning of the first open period following the announcement of the annual 
results. PAYE and NI are deducted and the net amount is used to purchase the actual shares delivered to each NED. Each NED has 
committed not to transfer or sell these shares during the term of their non-executive directorship.

The 2022 Bonus Plan Deferred Share Award will vest on 28 March 2024, subject to continuous employment.
Share Incentive Plan (SIP)
Since 2018, no awards have been granted under the SIP, except for dividend reinvestments.
Directors’ beneficial shareholdings and share interests
A shareholding guideline of two-times salary for all Executive Directors has been in effect from the date of the 2015 AGM. This level is 
to be built up over a period ending on the later of the fifth anniversary of appointment or the fifth anniversary of introduction of the 
policy. Until the shareholding guideline is achieved, an Executive Director is prohibited from selling any shares they have acquired 
through a Company scheme. They can, however, sell sufficient shares to satisfy any tax liability that may arise on the release or 
exercise of an award.
Interests in share awards following departure from the Company enable Executive Directors to remain aligned with the interests of 
shareholders for an extended period post-employment. For good leavers, deferred annual share awards, and LTIP awards subject to 
holding periods, will typically vest within normal timeframes.

Percentage change in remuneration
Abcam has an international workforce of approximately 1,800 employees in 13 locations. Due to the differing local pay levels 
across each of our overseas offices, the Committee considers the most meaningful comparator group to be the average 
remuneration of UK employees.
The following table shows the percentage change in remuneration between the years ended 31 December 2021 and 31 December 
2022 for the CEO, CFO, Non-Executive Directors and this comparator group as well as the prior year information (which covers the

Annual Report on Remuneration continued
The comparison with UK employees is specified by the regulations. This group comprises approximately 42% of our total employee 
population. The regulations provide flexibility to adopt one of three methods of calculation. We have chosen Option B for all elements 
of pay for each of the three years illustrated in the table above. The ratios are based on total pay which includes base salary, pension 
and benefits, bonus and equity awards under our share plans. The CEO annualised pay figure for the 12 months ended 31 December 
2022 is as shown in the single total figure of remuneration table on page 52. For UK employees, quartile data has been determined 
with calculations based on actual pay data as applied for Gender pay gap reporting for the April date preceding the year end. The 
value of company provided benefits for the indicative employees is calculated based on value of flexible benefit allowance provided 
to UK based employees.
The year-on-year movement in the CEO pay ratio can be volatile as CEO pay is more heavily weighted towards variable pay, and 
hence more variable (in line with Company performance) than employee pay. We believe that our CEO pay ratio is consistent with 
our pay, reward and progression policies and this is reflected in the longer-term trends which are monitored by the Committee. We 
have recently implemented the Abcam Growth Plan as the successor programme to AbShare, which ensures that all employees 
globally are incentivised and meaningfully rewarded for delivering Abcam’s strategic goals to 2024. This programme builds on the 
success of AbShare with another generous offer of equity participation for our people. Through this and a wide range of other 
people-centric initiatives, Abcam has continued to position itself as a great place to work, with employee engagement well above 
external benchmarks.

Remuneration Committee
The Committee advises the Board on overall Remuneration Policy on behalf of the Board, and with the benefit of advice from external 
consultants, the SVP, Human Resources and the Global Reward Director, it also determines the remuneration of the Executive Directors 
and proposes a fee for the Chairman of the Board of Directors (with the Chairman not being present for any discussions on his fee). 
The remuneration of the NEDs is determined by the Chairman and the Executive Directors.
The Committee formulates and applies the policy with consideration to the prevailing economic climate in the major economies in 
which the Group operates. It also observes the spirit of the Group’s core values, including responsible leadership in the external and 
internal social environment. Consequently, the Committee closely considers the Company’s performance in building both long-term 
value and a secure future for all stakeholders.
The Committee currently comprises five NEDs, each of whom the Company deems to be independent: Peter Allen, Sally Crawford, 
Mara Aspinall, Mark Capone and Giles Kerr. Sally Crawford is Chair of the Committee.
The Chief Executive Officer, Company Secretary, the SVP, Human Resources and Global Reward Director attend the Committee 
meetings by invitation and assist the Committee in the execution of its objectives, except when issues relating to their own 
compensation are discussed.

Annual Report on Remuneration continued
No Director is involved in deciding his or her own remuneration.
While it is the Committee’s responsibility to exercise independent judgement, the Committee does request advice from management 
and professional advisors, so as to be informed on the internal and external environment.
No member of the Committee has any personal financial interest, other than as a shareholder, in the matters to be decided by the 
Committee. The five independent members of the Committee have no conflicts of interest arising from cross-directorships. Members of 
the Committee have no day-to-day involvement in the running of the Company. The Committee met six times during the year. Details 
of attendance can be found in the Corporate Governance Report (see page 33).

FIT Remuneration Consultants during the year was objective and independent.
Statement of voting at general meeting
The table below shows the advisory vote on the 2021 Annual Report on Remuneration and on the current Directors’ Remuneration 
Policy at the 2021 General Meeting.
Whilst we were pleased to gain support for the 2021 Remuneration Policy, we recognise that there were a significant number of votes 
opposing these resolutions. We recognise the importance of stakeholder engagement when considering our Remuneration Policy 
and its future implementation and consulted extensively with shareholders prior to the General Meeting. The Committee was grateful 
for the time and contribution of all those shareholders who participated in the consultation process, and for the broad indications of 
support for Abcam’s management team and the principles underlying our proposals.
During the process we reviewed the key areas on which we received feedback (the maximum opportunity under the PGIP, the lack of 
a cap and the number of employee participants) and responded to this by reducing the overall quantum available to the Executive 
Directors, implementing a cap on the plan, and extending the participation of the plan to approximately 150 senior leaders in the 
Company. In addition, the Company has recently launched a new all employee share incentive plan globally.

We recognise that the revisions to our original proposals, while generally well received, were not considered sufficient to secure 
support from all shareholders. The Company has continued to hold follow up meetings with shareholders since the AGM and 
the Remuneration Committee continues to believe that the remuneration opportunity offered to Executive Directors is fair and 
competitive; aligns with the Company’s strategy and culture; and will ultimately support the long-term success of the business and 
the continued creation of sustainable long-term shareholder value.

Dividends
The Board continues to believe that the best way to create 
shareholder value over the long-term is to maximise value 
from the Group’s investments and to focus on growing Abcam 
sustainably. Accordingly, the Board has decided not to declare 
a final dividend. The Board will continue to review the Group’s 
dividend policy, with future distributions reflecting the cash 
generation and capital needs of the Company. This means 
the total dividend for the year ended 31 December 2022 was 0 
pence per share (2020/21: 0 pence).
Control and share structure
Details of the authorised and issued share capital, together 
with details of the movements in the Company’s issued share 
capital during the year, are shown in note 24 to the consolidated 
financial statements. The Company has one class of ordinary 
share which carries no right to fixed income. Each share carries 
the right to one vote at general meetings of the Company. 
There are no specific restrictions on the size of a holding nor on 
the transfer of shares, which are both governed by the general 
provisions of the Articles of Association and prevailing legislation. 
The Directors are not aware of any agreements between the 
holders of the Company’s shares that may result in a restriction 
on the transfer of securities or on voting rights. No person has 
any special rights of control over the Company’s share capital 
and all issued shares are fully paid.
Details of employee share schemes are set out in note 27 to the 
financial statements. Shares held by Equiniti Share Plan Trustees 
Limited abstain from voting.
Agreements affected by change of control
The Company is not party to any material agreements that 
take effect, alter or terminate upon a change of control of the 
Company following a takeover.
There are no agreements between the Company and its 
Directors providing for compensation for loss of office or 
employment (whether through resignation, redundancy or 
otherwise) that occurs because of a takeover bid. However, 
members of the Executive Leadership Team, excluding the 
Executive Directors, are entitled to an agreed sum equal to 
six months’ basic salary in the event of a dismissal for any 
reason other than misconduct, subject to the satisfaction of 
certain conditions.
Purchase of own shares
At the end of the year, the Directors had authority, under a 
resolution passed at a General Meeting of the Company on 
18 May 2022, to purchase through the market 22,890,856 of the 
Company’s ordinary shares, subject to the conditions set out in 
that resolution. No shares were purchased under this authority 
during the year under review.
Directors
A list of the current Directors of the Company is set out on 
page 33. Luba Greenwood was appointed as a non-executive 
director on 12 September 2022. All other directors were in office 
throughout the year and up to the date of signing the financial 
statements.
The powers of the Directors are determined by UK legislation and 
the Company’s Articles of Association, together with any specific 
authorities that may be given to the Directors by shareholders 
from time-to-time (for example the authority to allot or purchase 
shares in the Company).
The beneficial and non-beneficial interests of the Directors in the 
Company’s ordinary shares of 0.2 pence are disclosed in the 
Annual Report on Remuneration.
Re-election of Directors
The Chairman has determined that each individual 
demonstrates commitment to his or her role and displays 
effective performance; he is therefore recommending the 
re‑election of all Directors seeking to remain on the Board.
All Directors shall retire and all Directors shall stand for re-election 
at the AGM to be held on 17 May 2023.

Articles of Association
The rules governing the appointment and replacement of 
Directors are contained in the Company’s Articles of Association. 
The Articles of Association may be amended only by special 
resolution at a general meeting of shareholders.
Qualifying third party indemnity provisions
The Company has made qualifying third party indemnity 
provisions for the benefit of its Directors during the reporting 
period and these remain in force at the date of this report.
Directors’ and officers’ insurance
The Company has purchased and maintained throughout the 
financial year directors’ and officers’ liability insurance to cover 
any claim for wrongful acts in connection with their positions. 
The insurance provided does not extend to claims arising from 
fraud or dishonesty.
Going concern
The Group meets its day-to-day working capital requirements 
from the cash surpluses generated as a result of normal trading. 
In considering going concern, the Directors have considered the 
Group’s principal risks set out on page 30 and have reviewed 
the Group’s forecasts and projections, taking account of 
reasonably possible changes in trading performance. These 
show that the Group should be able to operate within the limits 
of its available resources.
Annual General Meeting
The AGM will be held at our registered office at Discovery Drive, 
Cambridge Biomedical Campus, Cambridge, CB2 0AX, UK on 
17 May 2023 at 1.30pm. A presentation will be made at this 
meeting outlining the recent developments in the business. 
All voting at the meeting will be conducted by show of hands 
where every shareholder present in person or by proxy will have 
one vote, unless a poll is requested by a shareholder for which 
each shareholder present or by proxy will have one vote for each 
share of which they are the owner.
The Group will publish the results of the votes on its 
website after the AGM. Shareholders are invited to submit 
written questions in advance of the meeting. Questions 
should be sent to the Company Secretary by email to 
company.secretary@abcam.com.
Details of the resolutions to be proposed at the meeting are set 
out in the Circular and Notice of AGM 2023, which will be made 
available to all shareholders, together with a proxy card.
Disabled employees
Abcam is an equal opportunities employer and ensures that 
applications for employment from people with disabilities 
and other under-represented groups are given full and fair 
consideration. Such individuals are given the same training, 
development and job opportunities as other employees 
and Abcam provides an accessible working environment in 
which reasonable adjustments are made during recruitment 
and employment. Every effort is made to retain and support 
employees who become disabled during their employment, 
including flexible working to assist their re-entry into the 
workplace and making alternative suitable provisions, along 
with a zero-tolerance approach to discrimination, bullying and 
harassment based on protected characteristics.
Statement of Directors’ responsibilities
The directors are responsible for preparing the Annual Report 
and Accounts and the financial statements in accordance with 
applicable law and regulation.
Company law requires the directors to prepare financial 
statements for each financial year. Under that law the directors 
have prepared the group financial statements in accordance 
with UK-adopted international accounting standards and the 
company financial statements in accordance with United 
Kingdom Generally Accepted Accounting Practice (United 
Kingdom Accounting Standards, comprising FRS 101 “Reduced 
Disclosure Framework”, and applicable law).
Under company law, directors must not approve the financial 
statements unless they are satisfied that they give a true and 
fair view of the state of affairs of the group and company and 
of the profit or loss of the group for that period. In preparing the 
financial statements, the directors are required to:
	–
select suitable accounting policies and then apply 
them consistently;
	–
state whether applicable UK-adopted international 
accounting standards have been followed for the group 
financial statements and United Kingdom Accounting 
Standards, comprising FRS 101 have been followed 
for the company financial statements, subject to any 
material departures disclosed and explained in the 
financial statements;
	–
make judgements and accounting estimates that are 
reasonable and prudent; and
	–
prepare the financial statements on the going concern basis 
unless it is inappropriate to presume that the group and 
company will continue in business.

Abcam plc Annual Report and Accounts 2022
62
Directors’ Report continued
The directors are responsible for safeguarding the assets of the 
group and company and hence for taking reasonable steps for 
the prevention and detection of fraud and other irregularities.
The directors are also responsible for keeping adequate 
accounting records that are sufficient to show and explain 
the group’s and company’s transactions and disclose with 
reasonable accuracy at any time the financial position of the 
group and company and enable them to ensure that the 
financial statements comply with the Companies Act 2006.
The directors are responsible for the maintenance and integrity 
of the company’s website. Legislation in the United Kingdom 
governing the preparation and dissemination of financial 
statements may differ from legislation in other jurisdictions.
Directors’ confirmations
The directors consider that the Annual Report and Accounts 
and accounts, taken as a whole, is fair, balanced and 
understandable and provides the information necessary for 
shareholders to assess the group’s and company’s position and 
performance, business model and strategy.
In the case of each director in office at the date the directors’ 
report is approved:
	–
so far as the director is aware, there is no relevant audit 
information of which the group’s and company’s auditors are 
unaware; and
	–
they have taken all the steps that they ought to have taken 
as a director in order to make themselves aware of any 
relevant audit information and to establish that the group’s 
and company’s auditors are aware of that information.
Provision of information to the auditor
Each Director in office at the date the Directors’ Report is 
approved confirms that:
	–
so far as the director is aware, there is no relevant audit 
information of which the group’s and company’s auditors are

Report on the audit of the 
financial statements
Opinion
In our opinion:
	–
Abcam plc’s group financial statements and company 
financial statements (the “financial statements”) give a 
true and fair view of the state of the group’s and of the 
company’s affairs as at 31 December 2022 and of the 
group’s loss and the group’s cash flows for the year then 
ended;
	–
the group financial statements have been properly prepared 
in accordance with UK-adopted international accounting 
standards as applied in accordance with the provisions of 
the Companies Act 2006;
	–
the company financial statements have been properly 
prepared in accordance with United Kingdom Generally 
Accepted Accounting Practice (United Kingdom Accounting 
Standards, including FRS 101 “Reduced Disclosure 
Framework”, and applicable law); and
	–
the financial statements have been prepared in accordance 
with the requirements of the Companies Act 2006.
We have audited the financial statements, included within the 
Annual Report and Accounts 2022 (the “Annual Report”), which 
comprise: the consolidated and company balance sheets as 
at 31 December 2022; the consolidated income statement, 
the consolidated statement of comprehensive income, the 
consolidated cash flow statement, and the consolidated and 
company statements of changes in equity for the year then 
ended; and the notes to the financial statements, which include 
a description of the significant accounting policies.
Basis for opinion
We conducted our audit in accordance with International 
Standards on Auditing (UK) (“ISAs (UK)”) and applicable law. 
Our responsibilities under ISAs (UK) are further described in the 
Auditors’ responsibilities for the audit of the financial statements 
section of our report. We believe that the audit evidence we 
have obtained is sufficient and appropriate to provide a basis for 
our opinion.
Independence
We remained independent of the group in accordance with 
the ethical requirements that are relevant to our audit of the 
financial statements in the UK, which includes the FRC’s Ethical 
Standard, as applicable to listed entities, and we have fulfilled 
our other ethical responsibilities in accordance with these 
requirements.
Our audit approach
Overview
Audit scope
	–
We conducted audits of the complete financial information of Abcam plc, Abcam Inc, Abcam 
(Netherlands) B.V. and Abcam Trading (Shanghai) Co., Limited.
	–
We performed specified procedures over certain account balances and transaction classes at other 
Group companies, including four entities in the US and one entity in each of China, Japan and Australia.
	–
With the exception of the audit of Abcam Trading (Shanghai) Co., Limited and certain specified 
procedures performed over another Chinese operation, which were performed by a component auditor, 
the Group engagement team performed all of the audit procedures.
	–
Taken together, the Group companies, as well as the consolidation adjustments, over which we performed 
our audit procedures accounted for 87% of the absolute loss before tax (i.e. the sum of the numerical 
values without regard to whether they were profits or losses for the relevant reporting units) and 80% of 
revenue.

	–
Performance materiality: £1.8m (2021: £1.6m (group) and £1.3m (2021: £1.3m) (company).
The scope of our audit
As part of designing our audit, we determined materiality and 
assessed the risks of material misstatement in the financial 
statements.
Key audit matters
Key audit matters are those matters that, in the auditors’ 
professional judgement, were of most significance in the audit 
of the financial statements of the current period and include the 
most significant assessed risks of material misstatement (whether 
or not due to fraud) identified by the auditors, including those 
which had the greatest effect on: the overall audit strategy; the 
allocation of resources in the audit; and directing the efforts of 
the engagement team. These matters, and any comments we 
make on the results of our procedures thereon, were addressed 
in the context of our audit of the financial statements as a whole, 
and in forming our opinion thereon, and we do not provide a 
separate opinion on these matters.
This is not a complete list of all risks identified by our audit.

Strategic Report

Financial statements
The provision for expected credit losses of trade receivables in Abcam Inc. is a new key audit matter this year. The valuation of 
BioVision, Inc. acquired intangible assets and the impairment assessment of all acquired intangible assets, which were key audit 
matters last year, are no longer included because of the one-off nature of the BioVision, Inc. acquisition and the decrease in 
estimation uncertainty around the impairment of acquired intangible assets, following the decision by management to discontinue 
the group’s investment in the Firefly Bioworks products and technology.
Key audit matter
How our audit addressed the key audit matter
Provision for expected credit losses of trade receivables in 
Abcam Inc. (group)
As described in Note 4 to the consolidated financial 
statements, accounts receivable and the provision for 
expected credit losses (‘ECL’) of trade receivables in Abcam 
Inc. was $54.8 million and $2.2 million, respectively, as of 
December 31, 2022. Management assesses the requirement 
for a provision of expected credit losses in line with the 
lifetime expected credit loss for trade receivables. The ECL 
is based upon the Group’s historical credit loss experience 
that is then adjusted to account for factors that are specific 
to the individual customer balances, the general economic 
conditions and the forecast conditions at the balance sheet 
date. In September of 2022, a new sales and distribution 
module within the ERP system was implemented which 
interrupted operations and resulted in delays in the Group’s 
(in particular Abcam Inc’s) ability to perform credit checks 
and distribute invoices timely. Amounts collected may be 
less than amounts billed due to untimely invoice distribution, 
prolonged delays in collection, and other reasons unrelated 
to credit risk. Management applied complex and subjective 
judgment in estimating the provision for ECL of trade 
receivables.
Addressing the matter involved performing procedures and 
evaluating audit evidence in connection with forming our 
overall opinion on the consolidated financial statements. These 
procedures included, among others, (i) testing management’s 
process for developing the estimate of the provision for ECL 
of trade receivables, (ii) evaluating the relevance and use of 
historical experience data as an input into the estimate, (iii) 
testing the completeness and accuracy of underlying data used 
in the estimate, (iv) testing, on a sample basis, the existence and 
accuracy of invoicing transactions and cash collections from the 
billing and collection data used in management’s estimate (v) 
understanding management’s plans for collecting outstanding 
accounts receivable and evaluating the ability to carry out those 
plans and (vi) performing subsequent cash receipt testing by 
comparing actual cash collections received subsequent to year-
end to related accounts receivable outstanding as of year-end to 
evaluate the reasonableness of management’s estimate..
We found no material exceptions in our testing.
How we tailored the audit scope
We tailored the scope of our audit to ensure that we performed enough work to be able to give an opinion on the financial 
statements as a whole, taking into account the structure of the group and the company, the accounting processes and controls, and 
the industry in which they operate.
The consolidated financial statements are a consolidation of 26 reporting units, comprising the Group’s operating businesses and 
holding companies. We performed audits of the complete financial information of Abcam plc, Abcam Inc, Abcam (Netherlands) B.V. 
and Abcam Trading (Shanghai) Co., Limited reporting units, which were individually financially significant, and over the consolidation 
adjustments. We also performed specified audit procedures over certain account balances and transaction classes that we 
regarded as material to the Group at seven further reporting units, four based in the US and one in each of China, Japan and 
Australia.
The Group engagement team performed all audit procedures, with the exception of the audit of Abcam Trading (Shanghai) Co., 
Limited and certain specified procedures performed over another Chinese operation which were performed by a component auditor 
in China. Our involvement in the work of the component auditor in China included regular communication, both before and during 
the performance of the procedures. In addition, the senior statutory auditor held discussions with the component auditor in China 
and the Group engagement team conducted a review of the working papers. Taken together, the Group companies as well as the 
consolidation adjustments, over which we performed our audit procedures, accounted for 87% of the absolute loss before tax (i.e. the 
sum of the numerical values without regard to whether they were profits or losses for the relevant reporting units) and 80% of revenue.
The impact of climate risk on our audit
As part of our audit we made enquiries of management to understand the extent of the potential impact of climate risk on the 
group’s and company’s financial statements, and we remained alert when performing our audit procedures for any indicators of the 
impact of climate risk. Our procedures did not identify any material impact as a result of climate risk on the group’s and company’s 
financial statements.
Materiality
The scope of our audit was influenced by our application of materiality. We set certain quantitative thresholds for materiality. These, 
together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our 
audit procedures on the individual financial statement line items and disclosures and in evaluating the effect of misstatements, both 
individually and in aggregate on the financial statements as a whole.

Abcam plc Annual Report and Accounts 2022

Based on our professional judgement, we determined materiality for the financial statements as a whole as follows:
Financial statements – group
Financial statements – company
Overall Group materiality
£3.6m (2021: £3.2m).
£2.7m (2021: £2.5m).
How we determined it
1% of revenue.
1% of revenue.
Rationale for benchmark applied
We believe that revenue is the primary 
measure used by the shareholders in 
assessing the performance of the Group 
and is a generally accepted auditing 
benchmark. Revenue is a key metric used 
in the Group’s five-year growth plan and 
also a key metric utilised within the Group’s 
incentive schemes, including the Group’s 
Profitable Growth Incentive Plan.
We believe that revenue is the primary 
measure used by the shareholders in 
assessing the performance of the Group, 
and is a generally accepted auditing 
benchmark. Revenue is a key metric used 
in the Group’s five-year growth plan and 
also a key metric utilised within the Group’s 
incentive schemes, including the Group’s 
Profitable Growth Incentive Plan.
For each component in the scope of our group audit, we 
allocated a materiality that is less than our overall group 
materiality. The range of materiality allocated across 
components was between £1.0m and £3.3m. Certain 
components were audited to a local statutory audit materiality 
that was also less than our overall group materiality.
We use performance materiality to reduce to an appropriately 
low level the probability that the aggregate of uncorrected 
and undetected misstatements exceeds overall materiality. 
Specifically, we use performance materiality in determining the 
scope of our audit and the nature and extent of our testing 
of account balances, classes of transactions and disclosures, 
for example in determining sample sizes. Our performance 
materiality was 50% (2021: 50%) of overall materiality, amounting 
to £1.8m (2021: £1.6m) for the group financial statements and 
£1.3m (2021: £1.3m) for the company financial statements.
In determining the performance materiality, we considered a 
number of factors – the history of misstatements, risk assessment 
and aggregation risk and the effectiveness of controls – and 
concluded that an amount at the lower end of our normal 
range was appropriate.
We agreed with those charged with governance that we would 
report to them misstatements identified during our audit above 
£0.18m (group audit) (2021: £0.16m) and £0.13m (company 
audit) (2021: £0.13m) as well as misstatements below those 
amounts that, in our view, warranted reporting for qualitative 
reasons.
Conclusions relating to going concern
Our evaluation of the directors’ assessment of the group’s and 
the company’s ability to continue to adopt the going concern 
basis of accounting included:
	–
We reviewed the Directors’ analyses and models. These 
included base case forecast assumptions and severe but 
plausible downside scenarios and considered whether these 
were reasonable and appropriate in light of our knowledge 
of the Group and Company.
	–
We challenged the forecasts and assumptions and 
confirmed the mathematical accuracy of the model.
	–
We validated the liquidity position of the Group and 
Company and in particular the extent of available cash and 
bank facilities and considered the extent of headroom these 
resources provided against the downside scenarios and 
loan covenants.
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 and the 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.
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.
However, because not all future events or conditions can be 
predicted, this conclusion is not a guarantee as to the group’s 
and the company’s ability to continue as a going concern.
Our responsibilities and the responsibilities of the directors with 
respect to going concern are described in the relevant sections 
of this report.
Reporting on other information
The other information comprises all of the information in the 
Annual Report other than the financial statements and our 
auditors’ report thereon. The directors are responsible for the 
other information. Our opinion on the financial statements 
does not cover the other information and, accordingly, we do 
not express an audit opinion or, except to the extent otherwise 
explicitly stated in this report, any form of assurance thereon.
In connection with our audit of the financial statements, our 
responsibility is to read the other information and, in doing 
so, consider whether the other information is materially 
inconsistent with the financial statements or our knowledge 
obtained in the audit, or otherwise appears to be materially 
misstated. If we identify an apparent material inconsistency or 
material misstatement, we are required to perform procedures 
to conclude whether there is a material misstatement of the 
financial statements or a material misstatement of the other 
information. If, based on the work we have performed, we 
conclude that there is a material misstatement of this other 
information, we are required to report that fact. We have nothing 
to report based on these responsibilities.
With respect to the Strategic report and Directors’ report, we 
also considered whether the disclosures required by the UK 
Companies Act 2006 have been included.
Based on our work undertaken in the course of the audit, the 
Companies Act 2006 requires us also to report certain opinions 
and matters as described below.

Financial statements
Strategic report and Directors’ report
In our opinion, based on the work undertaken in the course 
of the audit, the information given in the Strategic report and 
Directors’ report for the year ended 31 December 2022 is 
consistent with the financial statements and has been prepared 
in accordance with applicable legal requirements.
In light of the knowledge and understanding of the group and 
company and their environment obtained in the course of the 
audit, we did not identify any material misstatements in the 
Strategic report and Directors’ report.
Directors’ Remuneration
In our opinion, the part of the Annual Report on Remuneration to 
be audited has been properly prepared in accordance with the 
Companies Act 2006.
Responsibilities for the financial statements and the audit
Responsibilities of the directors for the financial statements
As explained more fully in the Statement of Directors’ 
Responsibilities, the directors are responsible for the preparation 
of the financial statements in accordance with the applicable 
framework and for being satisfied that they give a true and fair 
view. The directors are also responsible for such internal control 
as they determine is necessary to enable the preparation of 
financial statements that are free from material misstatement, 
whether due to fraud or error.
In preparing the financial statements, the directors are 
responsible for assessing the group’s and the company’s ability 
to continue as a going concern, disclosing, as applicable, 
matters related to going concern and using the going concern 
basis of accounting unless the directors either intend to liquidate 
the group or the company or to cease operations, or have no 
realistic alternative but to do so.
Auditors’ responsibilities for the audit of the financial 
statements
Our objectives are to obtain reasonable assurance about 
whether the financial statements as a whole are free from 
material misstatement, whether due to fraud or error, and to 
issue an auditors’ report that includes our opinion. Reasonable 
assurance is a high level of assurance, but is not a guarantee 
that an audit conducted in accordance with ISAs (UK) 
will always detect a material misstatement when it exists. 
Misstatements can arise from fraud or error and are considered 
material if, individually or in the aggregate, they could 
reasonably be expected to influence the economic decisions of 
users taken on the basis of these financial statements.
Irregularities, including fraud, are instances of non-compliance 
with laws and regulations. We design procedures in line with our 
responsibilities, outlined above, to detect material misstatements 
in respect of irregularities, including fraud. The extent to which 
our procedures are capable of detecting irregularities, including 
fraud, is detailed below.
Based on our understanding of the group and industry, we 
identified that the principal risks of non-compliance with laws 
and regulations related to the Companies Act 2006 and 
tax legislation, and we considered the extent to which non-
compliance might have a material effect on the financial 
statements. We evaluated management’s incentives and 
opportunities for fraudulent manipulation of the financial 
statements (including the risk of override of controls), and 
determined that the principal risks were related to posting 
inappropriate accounting entries to manipulate the financial 
statements and bias in estimates. The group engagement team 
shared this risk assessment with the component auditors so that 
they could include appropriate audit procedures in response to 
such risks in their work. Audit procedures performed by the group 
engagement team and/or component auditors included:
	–
discussions with management and those charged with 
governance, including known or suspected instances of non- 
compliance with laws and regulation and fraud;
	–
identifying and testing journal entries, in particular certain 
journal entries posted with unusual account combinations;
	–
designing audit procedures to incorporate unpredictability 
around the nature, timing or extent of our testing;
	–
reviewing meeting minutes, including those of the board of 
directors; and
	–
assessing assumptions made by management in their 
significant accounting estimates, including the provision for 
expected credit losses of trade receivables in Abcam Inc.
There are inherent limitations in the audit procedures 
described above. We are less likely to become aware of 
instances of non-compliance with laws and regulations that 
are not closely related to events and transactions reflected 
in the financial statements. Also, the risk of not detecting a 
material misstatement due to fraud is higher than the risk of 
not detecting one resulting from error, as fraud may involve 
deliberate concealment by, for example, forgery or intentional 
misrepresentations, or through collusion.
Our audit testing might include testing complete populations 
of certain transactions and balances, possibly using data 
auditing techniques. However, it typically involves selecting a 
limited number of items for testing, rather than testing complete 
populations. We will often seek to target particular items for 
testing based on their size or risk characteristics. In other cases, 
we will use audit sampling to enable us to draw a conclusion 
about the population from which the sample is selected.
A further description of our responsibilities for the audit of the 
financial statements is located on the FRC’s website at: www.frc.
org.uk/auditorsresponsibilities. This description forms part of our 
auditors’ report.
Use of this report
This report, including the opinions, has been prepared for and 
only for the company’s members as a body in accordance with 
Chapter 3 of Part 16 of the Companies Act 2006 and for no other 
purpose. We do not, in giving these opinions, accept or assume 
responsibility for any other purpose or to any other person to 
whom this report is shown or into whose hands it may come 
save where expressly agreed by our prior consent in writing.
Other required reporting
Companies Act 2006 exception reporting
Under the Companies Act 2006 we are required to report to you 
if, in our opinion:
	–
we have not obtained all the information and explanations 
we require for our audit; or
	–
adequate accounting records have not been kept by the 
company, or returns adequate for our audit have not been 
received from branches not visited by us; or
	–
certain disclosures of directors’ remuneration specified by law 
are not made; or
	–
the company financial statements and the part of the 
Annual Report on Remuneration to be audited are not in 
agreement with the accounting records and returns.
We have no exceptions to report arising from this responsibility.

Financial statements
1. Presentation of the financial statements
a) General information
Abcam plc (the Company) is a public limited company whose 
shares have been listed on NASDAQ since 2020 and were 
listed on the Alternative Investment Market (AIM) of the London 
Stock Exchange up until 14 December 2022 when Abcam plc 
delisted from AIM, is incorporated and domiciled in the UK and is 
registered in England under the Companies Act 2006.
b) Basis of preparation and consolidation
The consolidated financial statements incorporate the financial 
statements of the Company and the entities under its control 
(together the ‘Group’). Control is achieved when the Company 
has power to control the financial and operating policies of an 
entity either directly or indirectly and the ability to use that power 
to affect the returns it receives from its involvement with the entity.
The consolidated financial statements have been prepared 
in accordance with UK-adopted International Accounting 
Standards and with the requirements of the Companies Act 2006 
as applicable to companies reporting under those standards.
The consolidated financial statements have been presented in 
Sterling, the functional currency of the Company, and on the 
historical cost basis, except as modified to include revaluation of 
certain financial instruments to fair value.
On 2 June 2021, the Group announced that it was extending 
its current period from 30 June to 31 December. The financial 
statements are therefore presented for the year ended 
31 December 2022, while the comparatives are for the 18 month 
period ended 31 December 2021. As such, amounts presented 
in the financial statements are not directly comparable.
Consolidation of a subsidiary begins when the Group obtains 
control over the subsidiary and ceases when the Group loses 
control of the subsidiary. Where necessary, adjustments are 
made to the financial statements of subsidiaries to bring the 
accounting policies in line with those used by the Group. All 
intra-group transactions, balances, equity, income and expenses 
are eliminated on consolidation.
The Group’s directly and indirectly held subsidiary undertakings 
are disclosed in note C8 to the Company financial statements.
c) Adjusted performance measures
Adjusted performance measures are used by the Directors and 
management to monitor business performance internally and 
exclude certain cash and non-cash items which they believe 
are not reflective of the normal day-to-day operating activities 
of the Group. The Directors believe that disclosing such non-IFRS 
measures enables a reader to isolate and evaluate the impact 
of such items on results and allows for a fuller understanding of 
performance from year to year. Adjusted performance measures 
may not be directly comparable with other similarly titled 
measures used by other companies. A detailed reconciliation 
between reported and adjusted measures is presented in note 7.
d) Going concern
The Group meets its day-to-day working capital requirements 
from the cash surpluses generated as a result of normal trading. 
In considering going concern, the Directors have reviewed the 
Group’s forecasts and projections, taking account of reasonably 
possible changes in trading performance. These show that the 
Group should be able to operate within the limits of its available 
resources.
On 7 March 2023, the Group replaced its existing RCF which 
was due to expire on January 31 2024. The new RCF has a term 
of 4 years, with the option to extend for one further year, for an 
amount of £300m and with no accordion option. The amount of 
£120m drawn down on the previous RCF was rolled forward into 
the new facility. See note 31 for further details.
Accordingly, the Directors have a reasonable expectation that 
the Group has adequate resources to continue in operation 
for the foreseeable future and at least one year from the date 
of approval of the financial statements. For this reason, they 
continue to adopt the going concern basis in preparing its 
consolidated financial statements.

3. Principal accounting policies
The following paragraphs describe the main accounting 
policies, which have been applied consistently.
Revenue and income recognition
Revenue is measured at the fair value of the consideration 
received or receivable and represents amounts receivable 
for goods and services, net of discounts, VAT and other sales-
related taxes.
Revenue from sales of goods, including revenue generated from 
products sold from the Group’s catalogue and IVD and which 
represents the significant majority of the Group’s revenue, is 
recognised upon delivery to the customer or the point at which 
the customer takes control of the goods if this is sooner.
Custom product and service revenue, which can be the 
provision of a service or the development of products for 
customers, is recognised at the point at which a milestone, as 
defined in the contract, has been completed. Each milestone 
is typically aligned to a customer deliverable, for example, the 
amount of services provided, a deliverable arising from the 
services or the number of products successfully developed 
and provided to customers, and accordingly is considered to 
be a performance obligation. Every milestone has a defined 
transaction price. If it is identified that the costs will be in excess 
of the contract revenue, the expected loss is recognised as an 
expense immediately.
Licence fee income is recognised upon delivery of the licensed 
technology where the Group’s continued performance or future 
research and development services are not required. Royalty 
revenue is recognised on an accruals basis based on the 
contractual terms and the substance of the agreements with 
the counterparty, provided that the amount can be reliably 
measured and it is probable that the economic benefit will flow 
to the Group.
Leasing
Leased assets are capitalised on inception of the lease as right-
of-use assets. A corresponding lease liability, representing the 
present value of the lease payments is also recognised and split 
between current and non-current liabilities accordingly.
The lease liability includes; fixed payments, variable lease 
payments dependent on an index or rate (initially measured 
using the index or rate on the lease commencement date) and 
in substance fixed payments. The variable aspect of variable 
payments are recognised when the rate or index takes effect 
resulting in an adjustment to the liability and right-of-use asset. 
Currently the Group’s lease portfolio does not contain variable or 
in substance lease payments.
The discounted lease liability is calculated where possible 
using the interest rate implicit in the lease or where this is 
not attainable the incremental borrowing rate is utilised. The 
incremental borrowing rate is the rate the Group would have 
to pay to borrow the funds necessary to obtain a similar asset 
under similar conditions. The Group calculates the incremental 
borrowing rate using risk free rate of the country where the asset 
is held, adjusted for length of the lease and a risk premium.
Lease payments are allocated against the principal and 
finance cost. Finance costs, representing the unwinding of 
the discount on the lease liability are charged to the income 
statement to produce a constant periodic rate of interest on the 
remaining liability.
Right-of-use assets are measured at cost including; the 
discounted initial lease liability, lease payments made at or 
before the commencement date, any initial direct costs and 
reduced by any lease incentives received.
Right-of-use assets are depreciated over the shorter of the non-
cancellable lease period and any extension options that are 
considered reasonably certain to be taken or the useful life of 
the asset. The Group’s current leases run from 1–20 years.
Modifications to lease agreements result in remeasurement of 
the lease liability and right-of-use asset.
Short-term leases, defined as less than one year, and also 
of low value, are recognised on a straight-line basis in the 
income statement.
There are no material lease agreements where the Group acts 
as a lessor.
Foreign currencies
Foreign currency transactions are booked at the exchange 
rate ruling at the date of the transaction. Monetary assets and 
liabilities denominated in foreign currency are retranslated at the 
rates of exchange ruling at the balance sheet date. Exchange 
differences arising on settlement or retranslation of monetary 
assets and liabilities are included in the income statement.
The results of overseas subsidiaries are translated into Sterling 
using the average exchange rates during the year. Assets and 
liabilities are translated at the rates ruling at the balance sheet 
date. Goodwill arising on the acquisition of a foreign operation 
is treated as an asset of that foreign operation and as such is 
translated at the relevant foreign exchange rate at the balance 
sheet date. Exchange differences arising on this translation 
are recognised through other comprehensive income in the 
translation reserve.
Other exchange differences are recognised in the income 
statement in the period in which they arise except for where 
items are designated as hedging instruments or where there is a 
net investment hedge.
Retirement benefit costs
Payments to defined contribution retirement benefit schemes 
are charged as an expense as they fall due. The Group has no 
further obligations once the contributions have been paid.

3. Principal accounting policies continued
Taxation
Current tax payable is based on taxable profit for the year using 
tax rates that have been enacted or substantively enacted by 
the balance sheet date. Taxable profit differs from net profit as 
reported in the income statement because it excludes certain 
items of income or expense that are taxable or deductible in 
other years and further excludes items that are never taxable or 
deductible. Where the current tax deduction in respect of share 
option exercises exceeds the share option accounting charge 
for the period, the excess is recorded in equity rather than the 
income statement.
The benefit of UK research and development is recognised 
under the UK’s Research and Development Expenditure Credit 
(RDEC) scheme. The benefit is recorded as income included 
in profit before tax, netted against research and development 
expenses, as the RDEC is of the nature of a government grant.
Deferred tax is the tax expected to be payable or recoverable on 
differences between the carrying amount of assets and liabilities 
in the financial statements and the corresponding tax bases 
used in the computation of taxable profit, and is accounted for 
using the balance sheet liability method. Deferred tax liabilities 
are generally recognised for all taxable temporary differences 
and deferred tax assets are recognised to the extent that it is 
probable that taxable profits will be available against which 
deductible temporary differences can be utilised. Such assets 
and liabilities are not recognised if the temporary difference 
arises from the initial recognition of goodwill or from the initial 
recognition of other assets and liabilities in a transaction that 
affects neither the taxable profit nor the accounting profit.
Deferred tax liabilities are recognised for taxable temporary 
differences arising on investments in subsidiaries except where 
the Group is able to control the reversal of the temporary 
difference and it is probable that the temporary difference 
will not reverse in the foreseeable future. The Group’s liability 
for deferred tax is calculated using tax rates that have been 
enacted or substantively enacted by the balance sheet date 
that are expected to apply in the period when the liability 
is settled or the asset is realised. Deferred tax is charged or 
credited in the income statement, except where it relates to 
items charged or credited directly to other comprehensive 
income or reserves, in which case the deferred tax is also dealt 
with in other comprehensive income or reserves respectively.
Deferred tax assets and liabilities are offset when there is a 
legally enforceable right to set off current tax assets against 
current tax liabilities, they relate to income taxes levied by the 
same taxation authority and the Group intends to settle on a 
net basis.
Business combinations
Business combinations are accounted for using the acquisition 
method. On the acquisition of a business, fair values are 
attributed to the identifiable assets, liabilities and contingent 
liabilities unless the fair value cannot be reliably measured in 
which case the value is subsumed into goodwill.
If the initial accounting for a business combination is incomplete 
by the end of the reporting period in which the combination 
occurs, the Group reports provisional amounts for the items for 
which the accounting is incomplete. Those provisional amounts 
are adjusted during the measurement period or additional 
assets or liabilities are recognized to reflect new information 
obtained about facts and circumstances that existed as at 
the acquisition date that, if known, would have affected the 
amounts recognized as of that date. The measurement period 
is the period from the date of acquisition to the date the Group 
obtains complete information about facts and circumstances 
that existed as of the acquisition date – and is subject to a 
maximum of one year. Where measurement period adjustments 
are identified, comparative prior period is revised to reflect the 
change to the acquisition accounting.
Acquisition-related costs are expensed to the consolidated 
income statement in the period they are incurred.
Goodwill
Goodwill represents the excess of the fair value of the 
consideration over the fair value of the net assets acquired. 
Where the fair value of the consideration is less than the fair 
value of the acquired net assets, the deficit is recognised 
immediately in the income statement as a bargain purchase.
Goodwill is not amortised, but is subject to an impairment 
review at least annually and is carried at cost less accumulated 
impairment losses. Any impairment is recognised immediately in 
the income statement and is not subsequently reversed.
For the purpose of impairment testing, goodwill is allocated 
to cash generating units (CGUs). The CGU to which goodwill 
has been allocated is tested for impairment annually, or more 
frequently when there is an indication that the carrying value 
may not be recoverable.
Intangible assets
Acquisition intangibles:
Acquisition intangibles comprise licence fees, customer 
relationships and distribution rights, patents, technology and 
know-how and trade names. These are capitalised at fair value 
and amortised on a straight-line basis over their estimated useful 
lives. The principal expected useful lives are as follows:
Licence fees
Term of licence
Customer relationships and distribution rights
4 to 10 years
Patents, technology and know-how
10 to 16 years
Trade names
8 to 11 years
Patents, technology and know-how assets are only amortised 
once the development is complete and being utilised for their 
intended purpose; until this point the assets are deemed to be in 
progress.
Other intangibles:
These comprise software and expenditure on capitalised 
internally developed technology. Internally developed 
technology costs are recognised as an asset if and only if they 
meet the recognition criteria set out in IAS 38 ‘Intangible Assets’ 
which are that:
	–
the project must be technically feasible;
	–
there must be the intention to complete the project;
	–
there must be adequate resources to be able to complete 
the project;
	–
the ability to use or sell the asset or product is secure;
	–
the future economic benefits must exceed the costs; and
	–
the ability to reliably measure costs.

Notes to the consolidated financial statements continued
Year ended 31 December 2022
3. Principal accounting policies continued
Intangible assets are amortised on a straight-line basis over 
their estimated useful lives. Assets under construction are 
not amortised.
The principal expected useful lives are as follows:
Software
3 to 10 years
Internally developed technology
3 to 16 years
Patents and licences
2 to 3 years
During the period to 31 December 2021, the Group revised its 
estimate of the useful life of its software assets from 3 to 5 years 
to 3 to 10 years. Further details are shown in note 14.
Property, plant and equipment
Property, plant and equipment is stated at cost less 
accumulated depreciation and, where appropriate, provision for 
impairment in value. Cost includes the original purchase price 
of the asset and the costs attributable to bringing the asset to its 
working condition for its intended use. Depreciation is charged 
so as to write off the cost of assets over their estimated useful 
lives, using the straight-line method, as follows:
Laboratory equipment 
2 to 5 years
Cell line assets
10 years
Office fixtures, fittings and other equipment
2 to 5 years
Leasehold improvements
Term of lease
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 
income statement. Residual values of assets and their useful lives 
are assessed on an ongoing basis and adjusted, if appropriate, 
at each balance sheet date. Assets under the course of 
construction are not depreciated.
Impairment of property, plant and equipment and intangible 
assets excluding goodwill
A review is undertaken upon the occurrence of events or 
circumstances which indicate that the carrying amount may not 
be recoverable. In addition, any assets not yet available for use 
are tested for impairment annually.
The 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 it is not possible to determine the recoverable amount for an 
individual asset, the assessment is made for the asset’s cash-
generating unit (CGU).
Assets held for sale
Non-current assets and disposal groups are classified as held for 
sale only if available for immediate sale in their present condition 
and a sale is highly probable and expected to be completed 
within one year from the date of classification. Such assets are 
measured at the lower of carrying amount and fair value, less 
the cost of disposal, and are not depreciated or amortised.
Inventories
Inventories and work in progress are stated at the lower of cost 
and net realisable value. Cost comprises direct materials and, 
where applicable, direct labour costs and an attributable 
portion of production overheads that have been incurred in 
bringing the inventories to their present location and condition. 
The valuation methodology is on a weighted average cost basis, 
depending on the nature of the inventory, and net realizable 
value represents the estimated selling price less all estimated 
costs of completion and costs to be incurred in marketing, 
selling and distribution. Provision is made for obsolete, slow-
moving or defective items where appropriate.
Financial assets
Financial assets and financial liabilities are recognised on the 
Group’s balance sheet when the Group becomes a party to the 
contractual provisions of the instrument. The Group’s financial 
assets comprise cash and cash equivalents, receivables which 
involve a contractual right to receive cash from external parties, 
and investments.
Investments
Investments in shares are held at fair market value, with 
any revaluation gain or loss recorded through other 
comprehensive income.
Trade and other receivables
Trade receivables (excluding derivative financial assets) are 
recognised at cost less allowances for expected credit loss. The 
provision is based on the Group’s expected credit loss, which is 
calculated using the simplified approach for trade receivables 
based on historical data adjusted for forward looking information.
Cash and cash equivalents
Cash and cash equivalents comprise cash on hand and 
demand deposits and other short-term, highly liquid investments 
that are readily convertible to a known amount of cash and are 
subject to an insignificant risk of changes in value.
Financial liabilities
Financial liabilities are those which involve a contractual 
obligation to deliver cash to external parties at a future date.
Trade and other payables
Trade payables (excluding derivative financial liabilities) are 
non-interest bearing and are stated at cost which equates to 
their fair value.
Equity instruments
Equity instruments issued by the Group are recorded as the 
proceeds received, net of direct issue costs.
Derivative financial instruments
The Group uses forward contracts to manage the exposure 
to fluctuating foreign exchange rates in relation to forecast 
future transactions.

Financial statements
3. Principal accounting policies continued
Derivatives are initially recognised at fair value at the date a 
contract is entered into and are subsequently remeasured to 
their fair value at each balance sheet date. The resulting gain 
or loss is recognised in the income statement immediately 
unless the derivative is designated and effective as a hedging 
instrument, in which event the timing of the recognition 
in the income statement depends on the nature of the 
hedge relationship.
Hedge accounting
At the inception of a hedge relationship, the Group documents 
the relationship between the hedging instrument and the 
hedged item, its effectiveness along with its risk management 
objectives, and its strategy for undertaking various hedge 
transactions. The effectiveness is repeated on an ongoing basis 
during the life of the instrument to ensure that the instrument 
remains effective.
Hedge effectiveness is assessed via the dollar offset method, 
being the ratio of change in the cumulative fair value of the 
hedging instrument divided by the cumulative change in 
present value of the hedged item attributed to changes in the 
stated currency pair forward rate.
Cash flow hedges
The Group designates certain derivatives as cash flow hedges of 
highly probable forecast foreign currency transactions.
The effective portion of changes in the fair value of derivatives 
which are designated and qualify as cash flow hedges is 
deferred in other comprehensive income. Gains or losses relating 
to the ineffective portion are recognised immediately in the 
income statement.
Amounts deferred in other comprehensive income are recycled 
to the income statement in the periods when the hedged item is 
recognised in the income statement.
Hedge accounting is discontinued when the Group revokes 
the hedging relationship, the hedging instrument expires or is 
sold, terminated or exercised, or it no longer qualifies for hedge 
accounting. Any cumulative gain or loss in other comprehensive 
income at that time remains in other comprehensive income 
and is recognised when the forecast transaction is ultimately 
recognised in the income statement. When a forecast 
transaction is no longer expected to occur, the cumulative 
gain or loss in other comprehensive income is recognised 
immediately in the income statement.
Share-based payments
Equity settled share-based payments are measured at fair value 
(excluding the effect of non-market-based vesting conditions) at 
the date of grant and is expensed on a straight-line basis over 
the vesting period, based on the Group’s estimate of the number 
of shares that will eventually vest.
Share-based payments where vesting is by reference to external 
performance criteria (such as growth in an external index) 
are measured using the Monte Carlo simulation. Those which 
are subject only to internal performance criteria or service 
conditions are measured using the Black-Scholes model.
For all schemes, the number of options expected to vest 
is recalculated at each balance sheet date based on 
expectations of leavers prior to vesting. The number of options 
expected to vest for schemes with internal performance criteria 
is also adjusted based on expectations of performance against 
targets. No adjustments are made for expected performance 
against external or ‘market-based’ targets. Charges made to 
the income statement in respect of equity settled share-based 
payments are credited to equity.
For cash settled share-based payments, the Group recognises 
a liability for the services acquired, measured initially at the fair 
value of the liability. This liability is remeasured at each balance 
sheet date and at the date of settlement, with any changes in 
fair value recognised in the income statement.
Own shares
No gain or loss is recognised in the income statement on 
the purchase, sale, issue or cancellation of the Group’s own 
shares. Any difference between the carrying amount and the 
consideration is recognised in equity.
4. Critical accounting judgements and sources of estimation 
uncertainty
The preparation of financial statements requires management 
to make judgements, estimates and assumptions about the 
application of its accounting policies which affect the reported 
amounts of assets, liabilities, revenue and expenses. Actual 
amounts and results may differ from those estimates.
Judgements and estimates are evaluated regularly and are 
based on historical experience and other factors, including 
expectations of future events that are believed to be reasonable 
under the circumstances. Any revisions to accounting estimates 
are recognised in the period in which the estimate is revised.
a) Key accounting judgements
Capitalisation of intangible assets – internal software 
development
The Group capitalises internal software development costs, in 
particular internal staff costs, relating to the enhancement of 
the Group’s core IT systems architecture and developments. 
Judgement is required in applying the capitalisation criteria of 
IAS 38 ‘Intangible Assets’, differentiating between enhancements 
and maintenance. Those costs which are not treated as capital 
but are directly attributable to the Group’s system and process 
improvement project are treated as adjusting items.
In establishing the principles on which costs are capitalised, 
consideration is given to the nature of work being performed, 
whether the costs and the activities are incremental and 
whether the associated deliverables meet the characteristics of 
an asset. Processes are in place to evaluate this, and the same 
processes are used to confirm whether the expensed costs are 
related to the system and process improvement project so that 
classification as an adjusting item is appropriate.

4. Critical accounting judgements and sources of estimation 
uncertainty continued
Capitalisation of intangible assets – internally developed 
technology
The Group capitalises internal costs associated with internally 
developed technology as intangible assets as described further 
in notes 3 and 14. This requires judgement to determine that the 
characteristics of such assets meet the relevant criteria if IAS 38 
‘Intangible Assets’ for classification as an intangible asset.
Internal costs are capitalised as internally developed technology 
within intangible assets which are used to generate antibodies 
and kits. The point at which such internal costs are capitalised 
as well as their magnitude (whereby the amount capitalised 
comprises mainly of attributable salary costs and consumables 
used in the manufacture process) is a key area of judgement. 
A key area in respect of the stage of development of internally 
developed technology is subject to judgement as to when 
a product’s future economic value justifies capitalisation. 
Management reviews regularly these factors in order to 
determine that the costs meet the criteria for capitalisation as 
intangible assets.
During the prior period, an impairment was booked for assets 
relating to AxioMx where changes in scope of the project 
impacted on the usability of the historical work performed, 
details of which can be seen in notes 7 and 14.
Assessment of cash generating units (CGUs)
For the purposes of impairment testing, the Group identifies the 
CGU that is appropriate for the asset to be measured against if 
it is not possible to estimate the recoverable amount individually. 
The goodwill acquired in a business combination is allocated 
at acquisition to the CGU which is expected to benefit from that 
business combination.
The Group applies judgement in determining how integrated the 
acquired business is within the Group. Consideration is given to 
the product branding and ranges, whether the manufacturing 
and research and development has broadened since 
acquisition, whether sales and marketing activity is separate 
from the Group and how the business is monitored.
For the BioVision acquisition in October 2021, the Group had 
determined that the business was not sufficiently integrated into 
the Group at 31 December 2021 and therefore the goodwill 
associated with this acquisition was tested separately as part 
of a separate BioVision CGU. As at 31 December 2022, the 
acquired BioVision business had been fully integrated in to the 
Group’s operations and product portfolio and so the Goodwill 
arising from the BioVision acquisition has also been allocated to 
the Group CGU. Full details can be found in note 13.
b) Key sources of estimation uncertainty
Performance conditions associated with share based payment 
schemes
The Group operates a number of share-based payment 
schemes for its employees, many of which need to meet non-
market-based performance conditions in order to either partially 
or fully vest at the end of the vesting period. Management uses 
forecast financial information, such as expected revenue growth, 
to assess the likelihood of achieving performance conditions 
throughout the vesting period and adjusts the share-based 
payment charge to reflect the expected proportion of issued 
share awards that will vest. Where actual performance differs 
from management expectations during the vesting period, or 
there are changes to management’s estimates, this can result in 
a material change to the share-based payment charge in the 
period in which this change occurs.
Impairment assessment of assets held for sale
During the year ended 31 December 2022, the assets relating 
to Firefly BioWorks multiplex and assay technology were actively 
marketed, along with other assets relating to this technology 
and product range, which included an allocation of goodwill 
(£1.6m). Accordingly, these assets were classified as held for sale 
on the Group’s balance sheet during the year.
The group was not successful in locating a buyer and a decision 
was made by the directors to discontinue the group’s investment 
in these products and technology. As such an impairment 
charge of £18.3m has been recognised within R&D expenses 
within the income statement, with the carrying amount of the 
assets classified as held for sale written down to £nil. Further, 
associated deferred tax liabilities of £4.1m and other liabilities 
of £0.2m were also released to the income statement, as well as 
other costs associated with this decision of £0.2m. Details can be 
found in note 9.
Provision for expected credit losses
During the financial year a new ERP system module for sales 
and distribution was implemented which, in September 2022, 
interrupted operations and resulted in delays in Abcam’s ability 
to perform credit checks and distribute invoices in a timely 
manner, in particular in Abcam, Inc. Amounts collected may be 
less than amounts billed due to untimely invoice distribution, 
prolonged delays in collection and other reasons unrelated 
to credit risk. These factors make the valuation of accounts 
receivable more subjective.
Abcam assesses the requirement for a provision against bad or 
doubtful debts in line with the lifetime expected credit loss (‘ECL’) 
for the trade receivables. The ECL is based upon the Group’s 
historical credit loss experience that is then adjusted to account 
for factors that are specific to the individual customer balances, 
the general economic conditions and the forecast conditions at 
the balance sheet date. The evaluation of these historical and 
other factors involves complex, subjective judgments.
The valuation of trade receivables is adjusted for the expected 
credit loss in the form of a provision for bad and doubtful debts. 
Our collection procedures include: review of account aging; 
review of current sales activity; and direct contact with our 
payors. An uncollectible amount is written off to the provision 
after reasonable collection efforts have been exhausted. As of 
31 December 2022, the provision for bad and doubtful accounts 
balance was £2.4 million (31 December 2021: £0.8 million) which 
is included in accounts receivable, net of allowances on the 
Group’s Consolidated Balance Sheets and of which there is a 
provision of $2.2m (£1.8m) against a gross accounts receivable 
balance of $54.8m (£46.0m) within Abcam Inc.
Details on the ageing of trade receivables can be found in 
note 20.

5. Operating segments
Products and services from which reportable segments derive their revenues
The Directors consider that there is only one core business activity and there are no separately identifiable business segments which 
are engaged in providing individual products or services or a group of related products and services which are subject to separate 
risks and returns. The information reported to the Group’s Chief Executive Officer, who is considered the chief operating decision 
maker, for the purposes of resource allocation and assessment of performance is based wholly on the overall activities of the Group. 
The Group has therefore determined that it has only one reportable segment, which is ‘sales of antibodies and related products’. The 
Group’s revenue and assets for this one reportable segment can be determined by reference to the Group’s income statement and 
balance sheet.
The Group has no individual product or customer which contributes more than 10% of its revenues.
Geographical information
Revenues are attributed to regions based primarily on customers’ location. The Group’s revenue from external customers and 
information about its non-current segment assets (excluding deferred tax) is set out below:

(i)	 Comprises amortisation of fair value adjustments relating to the acquisition of BioVision, Inc as detailed in note 29. Following the acquisition, the Group recognised a fair value 
uplift of £5.8m ($7.7m) to inventory carried on the Group’s balance sheet. This adjustment is being amortised over 4 months from November 2021. Such costs are included 
within cost of sales.
(ii)	 During the year ended 31 December 2022, the assets relating to Firefly BioWorks multiplex and assay technology were actively marketed, along with other assets relating to this 
technology and product range. Accordingly, these assets were classified as held for sale on the Group’s balance sheet, which included an allocation of goodwill (£1.6m). The 
group was not successful in locating a buyer and a decision was made by the directors, in the second half of 2022, to discontinue the group’s investment in these products 
and technology. As such an impairment charge of £18.3m has been recognised within R&D expenses within the income statement, with the carrying amount of the assets 
classified as held for sale written down to £nil. Further, associated deferred tax liabilities of £4.2m and other liabilities of £0.2m were also released to the income statement, 
as well as other costs associated with this decision of £0.2m. Details can be found in note 9. The impairment charge is included within research and development expenses. 
During the year ended 31 December 2021 this charge comprises an impairment of internally developed technology assets relating to AxioMx, following an assessment of the 
work performed and costs capitalised to date. Following the review, it was concluded that as a result of changes in the scope and nature of the project to which the costs 
related, and the corresponding usability of historical work performed, £1.1m of internally developed technology assets were impaired. The impairment charge is included 
within research and development expenses.
(iii)	Comprises costs of the strategic ERP implementation which do not qualify for capitalisation and, for the year ended 31 December 2022, impairment charges of £0.7m (period 
ended 31 December 2021: £2.1m), as a result of a software asset developed as part of the ERP project that was no longer required. Such costs are included within selling, 
general and administrative expenses.
(iv)	Period ended 31 December 2021: Comprises legal and other professional fees associated with the acquisition of BioVision and other aborted acquisitions. Such costs are 
included within selling, general and administrative expenses.
(v)	 Year ended 31 December 2022: Integration and reorganisation costs relate to the integration of the acquired BioVision business as described in note 29 of £8.6m, the 
accelerated depreciation of a property lease that is no longer in use of £2.9m and de-listing and other set-up costs associated with having a sole listing on Nasdaq of £4.2m. 
£0.1m of integration and reorganisation costs are included within research and development expenses and the remaining £15.6m is included within selling, general and 
administrative expenses.
	
Period ended 31 December 2021: Integration and reorganisation costs relate to the integration of the acquired BioVision business a(comprising mainly legal and professional 
fees) of £1.0m, integration costs relating to Expedeon of £0.7m, and reorganisation costs in the US and Asia Pacific, relating to the ongoing reorganisation of the Group’s 
property portfolio of £4.0m
(vi)	Amortisation of £14.5m (period ended 31 December 2021: £10.1m) is included within research and development expenses, with the remaining £2.4m (period ended 
31 December 2021: £3.4m) included within selling, general and administrative expenses.
(vii)	Comprises share-based payment charges of £23.3m (period ended 31 December 2021: £25.2m) and employer’s tax contributions of £2.9m (period ended 31 December 
2021: £3.8m) thereon for all the Group’s equity- and cash-settled schemes. Charges of £2.6m (period ended 31 December 2021: £5.1m) are included in research and 
development expenses, with the remaining £23.6m (period ended 31 December 2021: £23.9m) included within selling, general and administrative expenses.

The criteria for classification as an Asset Held for Sale under IFRS 5 was met in May 2022, when active marketing of these assets had 
commenced, and these assets were classified as held for sale on the group’s balance sheet.
The group was not successful in locating a buyer and a decision was made by the directors, in the second half of 2022, to 
discontinue the group’s investment in these products and technology. As such an impairment charge of £18.3 m has been 
recognised within R&D expenses within the income statement, with the carrying amount of the assets classified as held for sale 
written down to £nil. Further, associated deferred tax liabilities of £4.1m and other liabilities of £0.2m were also released to the income

(i)	 Adjusted income tax charge excludes the tax effects of adjusting items which are set out in note 7.
The Group reported a net tax credit of £7.1m (period ended 31 December 2021: charge of £3.1m). The net tax charge is reduced 
below the standard rate of UK corporation tax due to the credit from the ‘patent box’ benefit in the UK, where a lower rate of tax is 
applied to profits on patented income. The effective tax rate on adjusted profits is 23.4% (period ended 31 December 2021: 14.9%).
The UK corporation tax rate for the year was 19.0% (31 December 2021: 19.0%). Taxation for other jurisdictions is calculated at the 
rates prevailing in the respective jurisdictions.
The Finance Act 2021 increased the UK corporation tax rate to 25% with effect from 1 April 2023. This 25% rate has been applied in the 
deferred tax valuations based on the expected timing of when such assets and liabilities will be recovered.

Basic EPS and adjusted basic EPS are calculated by dividing the earnings attributable to the equity shareholders of the parent by the 
weighted average number of shares outstanding during the year/period. Diluted EPS and adjusted diluted EPS are calculated on the 
same basis as basic EPS but with a further adjustment to the weighted average number of shares outstanding to assume conversion 
of all potentially dilutive ordinary shares. Such potentially dilutive ordinary shares comprise share options and awards granted to 
employees where the exercise price is less than the average market price of the Company’s ordinary shares during the year/period 
and any unvested shares which have met, or are expected to meet, the performance conditions at the end of the year/period.

See note 29 for details related to the measurement period adjustment to the accounting for the acquisition of BioVision.
Goodwill is converted at the exchange rate on the date of acquisition and retranslated at the balance sheet date.
Goodwill acquired in a business combination is allocated at acquisition to the Cash Generating Unit (CGU) which is expected to 
benefit from that business combination. Following the acquisition of BioVision, Inc. (as described in note 29), the acquired business 
has not been fully integrated into the Group’s operations as at 31 December 2021. As such, as at 31 December 2021 BioVision was 
considered a separate CGU, and goodwill arising from this acquisition has been allocated to a separate CGU and the remainder 
of the Group was considered to be one CGU, as previous acquisitions have been fully integrated into the Group’s operations and 
product portfolio. As at 31 December 2022, the acquired BioVision business had been fully integrated in to the Group’s operations 
and product portfolio and so the Goodwill arising from the BioVision acquisition has also been allocated to the Group CGU.
During the year ended 31 December 2022, the assets relating to Firefly BioWorks multiplex and assay technology were actively 
marketed, along with other assets relating to this technology and product range. Accordingly these assets were classified as Assets 
held for sale, which included an allocation from goodwill of £1.6m. The goodwill was allocated on the basis of the relative values of 
the operation disposed of and the portion of the cash-generating unit retained. This was determined with reference to the proportion 
of revenue related to these assets in comparison to the total revenue for the group, as recognised in the first half of 2022 which was 
when these assets were classified as an asset held for sale.
Goodwill is subject to an annual impairment review or more frequently if there are any indications that goodwill might be impaired. 
The review assesses the carrying amount of the group’s CGU, which is equivalent to the net assets of the group, in comparison to its 
recoverable amount. In the event that the CGU were impaired, the impairment loss would be allocated against the recorded goodwill 
first before any other assets within the CGU.
The reviews are carried out using the following criteria:
	–
The recoverable amount of the CGU is determined by fair value less costs to sell;
	–
The fair value less is determined with reference to the market capitalization of the Abcam plc group as at 31 December 2022;
	–
Costs to sell are deemed to be negligible in comparison to the overall recoverable amount.
The key assumptions considered most sensitive for the fair value calculations are:
	–
Movements in the share price and exchange rate
Based on the results of this analysis, management is satisfied that the recoverable amount of the group’s CGU, inclusive of the 
recorded goodwill, exceeds its carrying amount.
Management has performed a sensitivity analysis on each of the key assumptions mentioned above. Due to the significant 
headroom which exists between the recoverable amount and the carrying value, the Directors have concluded that there are no 
reasonable possible changes in any of these key assumptions which would cause the goodwill to exceed its recoverable amount.

Amortisation of £12.0m (period ended 31 December 2021: £14.5m) is included within research and development expenses and 
£14.4m (31 December 2021: £14.3m) is included within selling, general and administrative expenses.
During the year ended 31 December 2022, the assets relating to Firefly BioWorks multiplex and assay technology were actively 
marketed for sale, along with other assets relating to this technology and product range. These assets which included acquired 
patents, technology and know-how, software, and internally developed technology with a total carrying amount of £15.8m were 
classified as assets held for sale in May 2022.
During the year ended 31 December 2022, a £0.7m impairment charge was recognized in respect of capitalized software 
development that will no longer be used in the Group’s ERP implementation project (year ended 31 December 2021: £2.1m 
impairment charge). These impairment charges are included within selling, general and administrative expenses.
A further £0.3m impairment charge on internally developed technology was recorded in the year ended 31 December 2022 (£0.6m 
in the year ended 31 December 2021), relating to certain technology assets. The impairment charge is included within selling, general 
and administrative expenses.

14. Intangible assets continued
During the period ended 31 December 2021, an impairment was made of internally developed technology assets relating to the 
AxioMx business unit, following an assessment of the work performed and costs capitalised to date. Following the review, it was 
concluded that as a result of changes in the scope and nature of the project to which the costs related, and the corresponding 
usability of historical work performed, £1.1m of internally developed technology assets were impaired. The impairment charge is 
included within research and development expenses and is included in adjusting items.
Capital commitments at 31 December 2022 amounted to £2.3m (2021: £5.4m).

The average credit period taken for sales is 61 days (31 December 2021: 35 days). Trade and other receivables are non-interest 
bearing and generally on terms between 30 to 90 days. Trade receivables are provided for based on estimated irrecoverable 
amounts determined by specific circumstances as described in note 4.
The Group does not hold any collateral or other credit enhancements over its trade receivables, nor do they have a legal right to 
offset against any amounts owed to the counterparty.

See note 29 for details related to the measurement period adjustment to the accounting for the acquisition of BioVision.
At 31 December 2022, the Group had an average of 38 days of purchases (31 December 2021: 37 days) outstanding in trade 
payables (excluding accruals and deferred income). The Group has financial risk management policies in place to ensure that 
all payables are paid within the credit timetable. The Directors consider that the carrying amount of trade and other payables 
approximates to their fair value.
Deferred income includes contract liabilities of £3.2m (2021: £3.1m) which represent consideration received for performance 
obligations not yet satisfied, in delivering products or services to customers. All deferred income is to be recognised within the next 
financial year.

The loan comprises drawings on the Group’s three year £200.0m RCF which was entered into in February 2019 and is shown net of 
unamortised facility arrangement fees. The RCF has a £100.0m accordion option which may be requested with prior notice at any time 
up to six months of the termination date. The initial term of this RCF had two extension options of one year each whereby the Company 
exercised the option for a two year extension on 17 December 2020 such that on 7 January 2021, the Company received approval from 
all syndicate banks. This extends the expiry of the facility to 31 January 2024. All other terms of the facility remain unchanged.
On 23 November 2020, the Group repaid in full the sum of £107.0m which was drawn up until that point. On 19 October 2021, the 
Group drew £120.0m to fund the purchase of BioVision (as set out in note 29).
The Group is subject to financial covenants on the RCF and has complied with these at all testing points in both 2021 and 2022.
On 7 March 2023, the Group replaced its existing RCF which was due to expire on January 31 2024 with a new RCF for an amount 
of £300m. See note 31 for further details.

26. Financial instruments
Capital risk management
The capital structure of the Group comprises of cash and cash equivalents, a Revolving Credit Facility of £200m (with a £100m 
additional accordion option and an initial term of three years which was entered into in February 2019) and total equity attributable 
to the owners of the parent. The Group maintains a capital structure with the following objectives:
	–
to protect the ability of the Group to continue as a going concern and maintain sufficient available resources as protection for 
unforeseen events;
	–
to provide flexibility of resource for strategic growth and investment where opportunities arise; and
	–
to provide reasonable returns to shareholders whilst maintaining a limited level of risk.
As part of achieving these objectives the Group identifies the principal financial risk exposures that are created by the Group’s 
financial instruments and monitors them on a regular basis. These are considered to be foreign currency risk (a component of market 
risk), credit risk and liquidity risk.
Where appropriate the Group uses financial derivatives to help mitigate the key risks, the use of which is governed by the Group’s 
policies approved by the Board of Directors. The Group does not enter into or trade financial instruments, including derivative financial 
instruments, for speculative purposes.
Foreign currency risk
This is the risk that a change in currency rates causes an adverse impact on the Group’s performance or financial position.
The Group has transactions denominated in various currencies with the principal currency exposure being fluctuations in US Dollars 
(USD), Euros, Japanese Yen and Chinese Renminbi (RMB). Collectively these currencies make up approximately 90% of the Group’s 
revenue and cash inflows. Whilst a large portion of the manufacturing and research and development costs are USD and RMB, giving 
a natural offset against the currency inflows, the majority of administration costs remain as Sterling leaving an overall net currency 
inflow in the Group’s cash flows.
This remaining currency exposure is centrally managed with the objective being to secure a level of certainty of Sterling value for up 
to 90% of the future net exposure based on forecast cash flows expected to occur up to 18 months ahead. The Group uses forward 
currency contracts to achieve this objective and applies hedge accounting where applicable. Foreign currency forward contracts 
are valued using quoted forward exchange rates and yield curves matching maturities of the contracts.
No hedges were designated as ineffective in the year ended 31 December 2022.

Currency risk sensitivity analysis
The following table shows the sensitivity of the Group’s financial instruments to changes in exchange rates by detailing the impact on 
profit and other comprehensive income of a 10% change in the Sterling exchange rate against the relevant foreign currencies.
10% represents management’s assessment of a reasonably possible change in foreign exchange rates over a 12 month period.
The sensitivity analysis below only includes financial instruments denominated in non-functional currency and forward currency 
contracts outstanding at the reporting date and represents the impact of an immediate change in Sterling against other currencies.

The sensitivity analysis is limited to the year end exposure and therefore does not reflect the exposure and inherent risk during the year.
Liquidity risk
This is the risk that the Group will have insufficient funds available in the right currency to settle its obligations as they fall due.
The Group generates funds from operational activities in excess of its operational requirements and has substantial cash balances 
available for its current investment activities.
The Board reviews the funding requirement of the Group as part of the budgeting and long-term planning processes and considers 
as necessary alternative possible sources of funding where the requirement is not satisfied by the Group’s forecast operational cash 
generation.
The Group manages liquidity risk by maintaining an adequate level of easily accessible cash reserves, in a currency profile 
representative of the Group’s cost base and matching customer and supplier terms where possible. The Group also has access to 
daily currency trading facilities which provides the ability to convert currency within the agreed settlement limits as required.
On 7 March 2023, the Group replaced its existing RCF which was due to expire on January 31 2024. The new RCF has a term of 4 
years, with the option to extend for one further year, for an amount of £300.0m and with no accordion option. The amount of £120.0m 
drawn down on the previous RCF was rolled forward into the new facility. See note 31 for further details.

Credit risk
This refers to the risk that a counterparty will default on its contractual obligations resulting in financial loss to the Group.
The Group is exposed to credit risk on its financial assets; however, there is not deemed to be a significant exposure due to the nature 
of its customer base and the types of transaction that are undertaken.
Trade receivables consist of a large number of customers spread globally with the majority being in economically strong 
geographies. The Group’s customer base is predominantly government-funded institutions, pharmaceutical companies conducting 
research, and local distributors. The perceived risk of default is deemed to be low.
Further information on the Group’s trade receivable ageing and impairment can be found in note 20.
The Group generates significant levels of operational cash. Cash in excess of local operational requirements is remitted and managed 
centrally. Exposure to counterparty default risk is managed by limiting the concentration of funds and contracts held with individual 
financial institutions and ensuring funds are only placed with institutions or in products rated BBB- or above by Standard & Poor’s.
Interest rate risk
This refers to the risk that a potential change in interest rates will increase the group’s exposure to greater net finance costs and 
increased cash outflows in servicing debt. The Group is exposed to fluctuations in interest rates on its cash, cash equivalents and 
borrowings.
The Group’s interest rate risk consists of:
Floating interest rate risk, arising on any drawings under the RCF. Changes in floating interest rates affect finance expense and cash 
flows. Interest rates are set with reference to market interest rates such as SONIA; and interest rate risk associated with the Group’s cash 
deposits. The Group’s overall objective with respect to holding these deposits is to maintain a balance between security of funds, 
accessibility and competitive rates of return.
Exposure to interest rate risk is managed through optimizing the return on surplus funds, whilst maintaining sufficient liquidity to 
manage operating cash flows, as well as regular monitoring of debt levels and the cost of servicing these.
A 1% increase in the interest rates would have increased net annual finance expenses by £1.0m (2021: £0.6m). A 1% decrease would 
have decreased net annual finance expense by £1.0m (2021: £1.2m).

Financial instruments held at fair value
Financial instruments that are measured at fair value are classified using a fair value hierarchy that reflects the source of inputs used 
in deriving the fair value. The three classification levels are:
	–
Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;
	–
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); and
	–
Level 3: inputs for the asset or liability that are not based on observable market data (unobservable market inputs).

Level 1 investments comprise listed equity securities in Plexbio, Inc. See note 17 for further information.
Level 2 derivative financial instruments comprise forward foreign exchange contracts. The fair value is remeasured on a monthly basis 
with reference to available forward market rates and comparative instrument pricing.
Level 3 investments comprise non-listed equity securities in respect of a 13% stake in Brickbio, Inc. and, for the period ended 
31 December 2021, a 14% stake in Somaserve Limited. The fair value is determined to be equal to the carrying amount of the 
investment and is reviewed periodically based on information available about the performance of the underlying business.

The volatility of the options is based on the average of standard deviations of historical daily continuous returns on Abcam plc shares, 
looking back over the same period as the expected life of the option. The dividend yield is based on Abcam plc’s actual dividend 
yield in the past. The risk-free rate is the yield on UK government gilts at each date of grant.
LTIP: Full details of the performance conditions for the LTIP are shown in the Annual Report on Remuneration on page 51. All awards 
are subject to achievement of the performance conditions and can be exercised up to ten years after the grant date. Save as 
permitted in the LTIP rules, awards lapse on an employee leaving the Company.

DSA: For those employees entitled to participate in the annual bonus plan, a portion of the bonus is awarded in the form of shares 
for which there is a compulsory holding period of two years and a requirement for continued employment before these fully vest to 
the employees (deferred shares). The number of deferred shares granted is dependent on certain performance criteria, comprising a 
one-year profit target and achievement of strategic and personal objectives.
Share award plans: PGIP
In Summer 2021, the Company approved a new share scheme PGIP (Profitable Growth Incentive Plan) which aims to align the 
reward to shareholders and incentivise key management employees & the executive directors to deliver the revenue growth ambition 
underpinned by ROCE. Upon vesting in April 2025, and subject to certain performance conditions being met, vested shares will be 
released as soon as practicable and will expire 30 days from the vesting date. Certain awards within the PGIP are subject to tranche 
vesting with 25% of vested shares released immediately; 25% after six months; 25% after 12 months; and 25% after 18 months.

Abcam Growth Plan (AGP)
In Spring 2022, the Company launched a share scheme (Abcam Growth Plan) under which all employees globally, excluding those 
eligible for the PGIP, were eligible to receive shares. The scheme is split in to two components; an annual incentive and a strategic 
incentive. Participants can receive up to 10% of their salary annually under the annual incentive where annual customer focused 
and financial targets are met over the three year period of the scheme. The strategic incentive pays out at up to 30% of salary, where 
the Group’s growth targets are achieved by the end of the 2024 financial year.

AbShare
In Autumn 2018, the Company launched a share scheme (AbShare) where all employees globally, excluding Executive Directors, 
are eligible to participate. Each employee who participates is required to contribute 5% of their salary spread across three years 
(therefore equating to 1.67% per annum). Upon vesting in November 2021, and subject to certain performance conditions being met, 
the funds contributed have been used as consideration for the issue of the predetermined number of shares to the employee with 
the Company issuing a further 10 shares for each share issued.

SIP
Up until October 2018, all UK-based employees were eligible to participate in the SIP whereby employees could purchase shares in 
the Company. These shares are referred to as Partnership Shares and are held in trust on behalf of the employee. For every Partnership 
Share bought by the employee up to a limit of £1,800 per tax year the Company will give the employee one share (Matching Shares), 
provided the employee remains employed by the Company for a period of at least three years.
Employees must withdraw their shares from the plan upon leaving the Company and will not be entitled to the Matching Shares if 
they leave within three years of purchasing the Partnership Shares.
In addition to this, also up until October 2018, the Company also awarded shares to employees (Free Shares) with a value of up to 
£3,600 per tax year. There are no vesting conditions attached to the Free Shares, other than being continuously employed by the 
Company for three years from the date of grant.
The fair value of Matching Shares and Free Shares is determined as the market value of the shares at the date of grant. No valuation 
model is required to calculate the fair value of awards under the SIP. The fair value of an equity-based payment under the SIP is the 
face value of the award on the date of grant because the participants are entitled to receive the full value of the shares and there 
are no market-based performance conditions attached to the awards.

pension provider. For each member the Company contributes a fixed percentage of salary to the scheme.
Employees of the Group’s subsidiaries in the US, Japan, China and Hong Kong are members of state-managed retirement benefit 
schemes. Depending on location, the subsidiaries are required to contribute a specified percentage of payroll costs to the retirement 
benefit schemes to fund the benefits.

29. Business combinations
Year ended 31 December 2022
No business combinations were undertaken during the period.
During the 12 month period after the BioVision acquisition was completed, several measurement period adjustments were identified 
for new information obtained about facts and circumstances that existed as of the acquisition date.
Following the completion of the acquisition, Abcam successfully claimed $18.0m (£13.1m at the exchange rate on the date of 
acquisition) from the escrow account established for the purpose of the BioVision acquisition following the discovery of previously 
undisclosed contractual terms with a significant customer of BioVision. A reduction in consideration of $18.0m (£13.1m) has been 
recognised in relation to this, as well as a corresponding liability for exiting this contract (which had been paid during the 12 months 
ended 31 December 2022). A deferred tax asset of $3.8m (£2.7m at the exchange rate on the date of acquisition) which has also 
been recognised on the opening balance sheet of BioVision in relation to this transaction.
In addition to the above, other liabilities totalling $2.0m (£1.4m at the exchange rate on the date of acquisition) were identified 
during the year after the acquisition was completed. The total adjustment to goodwill was $1.8m (£1.3m at the exchange rate on the 
date of acquisition).
As at 31 December 2021, there was a claim for a £1.1m adjustment to the consideration, which was adjustable for certain net 
working capital balances for which an estimate had been provided at the acquisition completion date. This was recognised as a 
receivable on the Group’s consolidated balance sheet as at 31 December 2021 and the claim was resolved and the cash for this 
was received during the 12 months ended 31 December 2022.
Period ended 31 December 2021
On 26 October 2021, Abcam US Group Holdings Inc., a subsidiary of Abcam Plc, acquired 100% of the issued share capital of NKY 
Biotech US, Inc. from Boai NKY Biotech Co. Ltd for initial total cash consideration of $349.9m (£253.8m) and acquisition expenses of 
£7.8m. NKY Biotech US, Inc. has one wholly owned subsidiary, BioVision, Inc. (collectively ‘BioVision’). BioVision is a leading provider of 
biochemical and cell-based assays for biological research. It also develops, produces, and sells a wide portfolio of other products 
including recombinant proteins, antibodies, enzymes, and biochemical compounds.
The acquisition accelerates Abcam’s strategic ambitions within the adjacent biochemical and cellular assay market and aligns with 
existing areas of research focus including oncology, immuno-oncology, neuroscience, and epigenetics.

Prior to acquisition, BioVision was a supplier of products to Abcam and there was a trading balance of £1.4m outstanding at the 
acquisition. As such, the consideration and total identifiable net assets acquired have been adjusted to reflect this pre-existing 
relationship, which was effectively settled upon acquisition.
The goodwill recognised is attributable to the expertise of the assembled workforce, potential new technology and products and 
leveraging Abcam’s global channels to market.
Since the date of acquisition to 31 December 2021 the acquisition contributed £2.6m to the Group’s revenue and a loss before tax 
of £2.6m. The effect on adjusted profit before tax was £1.4m which is before taking into account the effects of the amortisation of 
acquisition intangibles and amortisation of fair value adjustments as described in note 7.
Had BioVision been acquired on 1 July 2020, the Group revenue would have been £490.4m, the profit before tax would have been 
£29.3m and the adjusted profit before tax would have been £110.4m.

31. Subsequent events
On 7 March 2023, the Group replaced its existing RCF which was due to expire on January 31 2024 with a new RCF for an amount 
of £300m.
In February 2019, the Group entered into an RCF with a syndicate of banks for £200m with an additional £100m accordion option. The 
Group drew down £120m on the RCF to fund the BioVision acquisition in October 2021, and the RCF remained drawn in this amount 
as of 31 December 2022.
The new RCF has a term of 4 years, with the option to extend for one further year, for an amount of £300m and with no accordion 
option. The amount of £120m drawn down on the previous RCF was rolled forward into the new facility.
Borrowings under both the existing facility and the new facility are unsecured but are guaranteed by certain of our material 
subsidiary companies.

Notes to the Company financial statements
Year ended 31 December 2022
C1. Basis of preparation
The Company is incorporated in the United Kingdom and the separate financial statements of the Company have been presented 
as required by the Companies Act 2006.
The financial statements have been prepared under the historical cost convention (as modified to include revaluation of certain 
financial instruments to fair value) and on the going concern basis (see note 1 to the consolidated financial statements). The 
Company meets the definition of a qualifying entity under FRS 100 (Financial Reporting Standard 100) issued by the Financial 
Reporting Council. Accordingly, the financial statements have been prepared in accordance with FRS 101 ‘Reduced Disclosure 
Framework’ except for the departure explained in note C4 and in accordance with the Companies Act 2006 as applicable to 
companies using FRS 101.
As permitted by FRS 101, the Company has taken advantage of the disclosure exemptions available under that standard in relation to:
	–
Business combinations.
	–
Share-based payments.
	–
Financial instruments.
	–
Fair value measurement.
	–
Statement of cash flows.
	–
Certain related party transactions including those with subsidiaries.
	–
Certain plant, property and equipment disclosure.
	–
Certain impairment testing related disclosures.
	–
The effects of new but not yet effective IFRSs.
The basis for the above exemptions is because equivalent disclosures are included in the Group financial statements in which the 
entity is consolidated.
The adopted principal accounting policies, which have been applied consistently, are the same as those set out in note 3 to the 
consolidated financial statements except as noted below in respect of those which are Company specific.
Investments
Investments in subsidiaries are stated at cost plus capital contributions less, where appropriate, provisions for impairment. Where 
applicable, acquisition costs incurred in acquiring the subsidiary are capitalised as part of the investment cost.
Critical accounting judgements and estimates
The preparation of the Company financial statements in conformity with FRS 101 requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities at the 
date of the Company financial statements and the reported amounts of revenue and expenses during the reporting period. Actual 
results could differ from those estimates. The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions 
to accounting estimates are recognised in the period in which the estimate is revised. The critical accounting judgements and 
estimates are those set out in note 4 of the consolidated financial statements. These judgements have been applied consistently 
within the Company financial statements, where applicable.
C2. Income statement
In accordance with the exemption permitted by section 408 of the Companies Act 2006, the Company has elected not to present its 
own income statement or statement of comprehensive income for the year.

C3. Employees and remuneration
Details of Directors’ remuneration, share-based payments and pension entitlements in note 30 to the consolidated financial 
statements and the Annual Report on Remuneration on pages 49 to 59 form part of these Company financial statements. Information 
on the main employee share-based payments is given in note 27 of the consolidated financial statements. Details of the key 
management personnel are given in note 30 of the consolidated financial statements.
The average monthly number of employees (including Executive Directors) was:

The Companies Act Accounting Regulations require goodwill to be amortised, however, the Company has chosen not to do so 
but instead an annual impairment test is performed with any impairment identified being recognised as a charge to the income 
statement. This is a departure from the Companies Act 2006, for the overriding purpose of providing a true and fair view in line with 
the requirements of FRS 101.
A finite life for the goodwill has not been identified; however, the effect of amortising over a useful life of 20 years would be an income 
statement charge of £2.1m (period ended 31 December 2021: £3.2m) and a reduction of £7.5m (period ended 31 December 2021: 
£5.4m) in the carrying value of goodwill in the balance sheet.
Impairment review
Goodwill is tested for impairment on an annual basis in accordance with IAS 36 ‘Impairment of assets’ or more frequently if there are 
any indications that the goodwill might be impaired. These reviews are carried out using the same criteria as set out in note 13 to the 
consolidated financial statements.
A sensitivity analysis has been performed on each base case assumption used for assessing the goodwill with other variables held 
constant. Consideration of the sensitivities to key assumptions can evolve from one financial year to the next. The Directors have 
concluded that there are no reasonably possible changes in key assumptions which would cause the carrying amount of goodwill 
to exceed its value in use.

The Group’s performance is assessed using a number of financial measures which are not defined under IFRS and are therefore non-
GAAP (or alternative) performance measures. These are set out as follows:
	–
CER is a measure which allows management to identify the relative year-on-year performance of the business by removing the 
impact of currency movements which are outside of management’s control.
	–
Margin percentages (which are calculated by dividing the relevant profit figure by revenue) for each of the relevant profit metrics 
provide management with an insight into relative year-on-year performance.
	–
Adjusted profit measures, as described in note 1(c) to the consolidated financial statements, are believed by the Directors to 
enable a reader to obtain a fuller understanding of underlying performance since they exclude items which are not reflective of 
the normal course of business. Furthermore, such measures are reflective of how performance is measured internally including 
targets against which compensation is determined. Adjusted profit measures are derived and reconciled to their reported IFRS 
equivalent on the face of the consolidated income statement as well as in note 7 to the consolidated financial statements.
	–
The key adjusted profit measures comprises adjusted operating profit.
	–
Adjusting items (which are excluded to arrive at adjusted performance measures) are also described on the face of the income 
statement and in note 7 to the consolidated financial statements.
	–
Adjusted earnings per share measures are derived from adjusted profit after tax with the rationale for their use being the same as 
for adjusted profit metrics and are reconciled to their IFRS equivalent in note 11 to the consolidated financial statements.
	–
Free Cash Flow is defined on the face of the consolidated cash flow statement and provides management with an indication of 
the amount of cash available for discretionary investing or financing after removing capital related items.

Technical glossary
Agonists, Antagonists, Activators and Inhibitors (AAAI)
Biochemicals which activate or inhibit biological pathways.
Affinity Binder
A reagent that binds specifically to an antigen – antibodies are 
a subset of affinity binders.
Amino acids
The basic building blocks of proteins and peptides.
Antibody
A protein made by the immune system that binds specifically to 
an antigen. When an antibody detects this antigen in the body, 
it will contribute to an immune response to rid the body of the 
antigen.
Antigen
A molecule that is recognised by the immune system and which 
can be specifically bound by an antibody.
Assay
A laboratory test for assessing the presence, amount or 
functional activity of a chemical or biological molecule.
Biological pathway
A series of molecular interactions that leads to a change in a 
cell in response to a stimulus. For example, biological pathways 
can trigger the assembly of new molecules, turn genes on and 
off, or spur a cell to move.
Biological therapeutics
Any pharmaceutical drug product manufactured in, extracted 
from, or semi-synthesised from biological sources. Different from 
totally synthesised pharmaceuticals, they include vaccines, 
blood, blood components, allergenics, somatic cells, gene 
therapies, tissues, recombinant therapeutic protein, and living 
cells used in cell therapy.
Biomarker
A measurable indicator of a biological state or condition. For 
example, increased amounts of a particular protein in a blood 
sample may indicate the presence of a particular disease.
Conjugated antibody
Antibodies that are chemically bound to molecules that enable 
detection of the antibody. For example, an antibody might be 
bound to a fluorescent dye.
CRISPR CAS9
An experimental technique allowing effective and specific 
editing of genetic sequences.
DNA
Deoxyribonucleic acid – a polymeric molecule that comprises 
both the coding and non-coding elements of the genome of an 
organism. Coding elements are transcribed into RNA, while non-
coding elements exert cellular control functions.
ELISA
Assay that uses antibodies to detect and quantify proteins and 
peptides in a biological sample. Acronym for enzyme-linked 
immunosorbent assay.
Epigenetics
The study of changes in organisms caused by modification of 
gene expression rather than alteration of the genetic code itself.
ERP
Acronym for Enterprise Resource Planning. It refers to business 
process management software that allows an organisation to 
use a system of integrated applications to manage the business 
and automate many back-office functions related to technology, 
services and human resources.
Gene
A section of DNA that acts as the blueprint for making a 
particular protein. Every human being (except identical twins) 
has a unique set of genes, half of which came from their mother 
and the other half from their father.
Immunoassay
A test that uses the binding of antibodies to antigens to detect 
and quantify a biological molecule in a sample.
Immunology
A branch of biology that focuses on immune systems.
Immunohistochemistry (IHC)
The process of selectively imaging antigens (proteins) in cells of 
a tissue section by exploiting the principle of antibodies binding 
specifically to antigens in biological tissues
In vitro
Describes studies that are performed with microorganisms, cells 
or biological molecules outside their normal biological context. 
For example, an in vitro experiment might involve extracting a 
blood sample from a patient and performing an assay on that 
sample in a test tube.
In vivo
Describes a biological process that takes place in a living cell or 
organism, including animals and plants.
In vitro diagnostics (IVD)
Tests done on samples such as blood or tissue that have been 
taken from the human body. In vitro diagnostics can detect 
diseases or other conditions, and can be used to monitor a 
person’s overall health to help cure, treat, or prevent diseases.
Kits and assays
Multi-component products comprising antibodies and other 
reagents that can be used to detect a wide range of biological 
molecules.
Knockout cell lines
A cell line that has had a particular gene removed (or ‘knocked 
out’). The protein that the knocked-out gene encodes for is 
therefore not produced.
Lysate
The fluid produced by lysis of cells and tissues. Lysates are used 
as controls in biological experiments to confirm the absence or 
presence of proteins of interest.
Lysis
The disruption of cells by mechanical, chemical or enzymatic 
means.
M-phase phospho-proteins
A family of proteins with diverse roles in cellular signalling and 
gene expression.

Technical glossary
Matched antibody pairs
A pair of antibodies that binds to an individual protein at 
different sites, meaning that both antibodies of the pair can bind 
the protein at the same time. Matched antibody pairs are used 
in assays such as ELISA.
microRNA or miRNA
Small RNAs that are involved in regulating gene expression.
Monoclonal antibodies
Identical antibodies derived from a group of identical cloned 
cells or from an expression vector. Monoclonal antibodies 
recognise only one kind of antigen, i.e. they bind to the same site 
on a protein.
Multiplex immunoassays
Immunoassays that can detect multiple proteins at once within 
a single sample. They allow scientists to increase the efficiency 
and scope of their experiments.
Next generation sequencing
An experimental technique allowing high throughput analysis 
of genetic sequences. Used by Abcam to analyse the immune 
response to select the best monoclonal antibodies for a given 
target or application.
