MARKET AND INDUSTRY DATA

We obtained the industry, market and competitive position data in this prospectus from our own internal estimates, surveys and research as well as from publicly available information, industry and general publications and research, surveys and studies conducted by third parties, such as reports by CiteAb, a compiler and provider of citation data to the life science industry that uses its proprietary text mining technology and extensive human validation to search millions of scientific publications, EvaluatePharma, Pharmaprojects, Centers for Medicare and Medicaid Services and Pivotal Scientific.

Our estimates of our addressable market include several key assumptions based on our industry knowledge, industry publications, and third-party research, as well as other surveys. Moreover, these estimates of our addressable market are based on analyzing five specific markets, their current market size value and their estimated growth rates. These markets include: (1) Immunohistochemistry (a type of tissue diagnostic), (2) Tissue Diagnostic, (3) Diagnostic Specialty Antibody Market, (4) Research Antibodies and (5) Therapeutic Antibodies. The information and data we have relied on in determining our estimates is obtained from: (i) MarketsandMarkets; (ii) Grand View Research; (iii) Market Data Forecast; (iv) Market Study Report; (v) Future Market Insight; (vi) Transparency Market Research; (vii) Mordor Intelligence; (viii) Nova One Advisor; (ix) Research and Markets; (x) Biospace; and (xi) Polaris Market Research. While we believe that our internal assumptions are reasonable, the sources we have relied on may be based on a small sample size and may fail to accurately reflect market opportunities. Moreover, no independent source has verified such assumptions, and we did not commission any of the market and industry data presented in this prospectus. Industry publications, research, surveys, studies and forecasts generally state that the information they contain has been obtained from sources believed to be reliable but that the accuracy and completeness of such information is not guaranteed. Forecasts and other forward-looking information obtained from these sources are subject to the same qualifications and uncertainties as the other forward-looking statements in this prospectus. These forecasts and forward-looking information are subject to uncertainty and risk due to a variety of factors, including those described under “Risk Factors.” These and other factors could cause results to differ materially from those expressed in the forecasts or estimates from independent third parties and us.

RISK FACTORS

An investment in our ADSs involves a high degree of risk. You should carefully consider the risks and uncertainty described below, together with all of the other information in this prospectus, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes, before deciding to invest in our ADSs. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. Our business, financial condition or results of operations could be materially and adversely affected by any of these risks. The trading price and value of our ADSs could decline due to any of these risks, and you may lose all or part of your investment.

Risks Relating to our Business and Industry

A regional or global health pandemic, including COVID-19, could severely affect our business, operating results and financial condition due to impacts on our operations and supply chains, as well as actions taken to contain the disease or treat its impact and the speed and extent of the recovery.

We engage in business globally, which subjects us to a number of unpredictable or unexpected risks and factors outside our control, including risks associated with public health crises such as epidemics and pandemics. In December 2019, a novel coronavirus (SARS-CoV-2) was reported and in March 2020, the World Health Organization (“WHO”) characterized the COVID-19 outbreak as a pandemic. The COVID-19 pandemic has adversely affected global economies, financial markets and the overall environment in which we do business, and the extent to which it may impact our future results of operations and overall financial performance remains uncertain.

The COVID-19 pandemic is adversely affecting, and is expected to continue to adversely affect, elements of our business (including elements of our operations, supply chains and distribution systems) as a result of impacts associated with preventive and precautionary measures that we, other businesses, our communities and governments are taking. Many employers in our primary locations of business, including the United States, United Kingdom and China, temporarily closed sites and required their employees to work from home or not work at all. These site closures included some of our customers’ labs, which have caused and may continue to cause customers to delay or forego purchases of our products. During the pandemic, we have experienced significant and unpredictable reductions or increases in demand for certain of our products and may continue to experience such unpredictability in the future. Further, as the research community began to focus on COVID-19, other types of research were put on hold, which resulted in many of our customers’ research labs being forced to temporarily shut down or to operate at reduced capacity. As a substantial majority of our catalogue revenue is purchased for research use only, these shutdowns and reductions in capacity have negatively impacted the global demand for our products, which has resulted in a decrease in revenue. We also saw a reduction in demand due to the ongoing COVID-19 pandemic, particularly in North America where the number of COVID-19 cases is rising in several states with large research lab demand. While many of our customers’ labs have reopened, such labs may be required to continue to operate at reduced capacity, and there can be no assurance that our customers will not be subject to further shutdowns or reductions in capacity in the future, which could have a material adverse effect on our business and results of operations. As the impact of the COVID-19 pandemic remains uncertain, we may continue to experience decreased sales activity.

In an effort to halt the outbreak of COVID-19, many countries throughout the world have placed significant restrictions on travel, and many jurisdictions may continue to close borders, impose prolonged quarantines and further restrict travel and business activity, which could significantly impact our ability to support our operations and customers, the ability of our employees to get to their workplaces to produce products and provide services and the availability of materials for production of our products, as well as significantly hinder or increase the costs associated with our products from moving through the supply chain. Due to uncertainties that will be dictated by the length of time that the COVID-19 pandemic and related disruptions continue, there can be no assurance that our operations will not continue to be adversely impacted.

23

Table of Contents

During the COVID-19 pandemic, we asked that all employees who are able to do so work remotely, and it is possible that widespread remote work arrangements could have a negative impact on our operations, the execution of our business plans and productivity and availability of key personnel and other employees necessary to conduct our business, and of third-party service providers who perform critical services for us, or otherwise cause operational failures due to changes in our normal business practices necessitated by the outbreak and related governmental actions. If a natural disaster, power outage, connectivity issue, or other event occurred that impacted our employees’ ability to work remotely, it may be difficult or, in certain cases, impossible, for us to continue our business for a substantial period of time. The increase in remote working may also result in consumer privacy, IT security and fraud risks, and our understanding of applicable legal and regulatory requirements, as well as the latest guidance from regulatory authorities in connection with the COVID-19 pandemic, may be subject to legal or regulatory challenge, particularly as regulatory guidance evolves in response to future developments.

Further, in connection with the global COVID-19 pandemic and in an effort to increase the wider availability of needed medical and other supplies and products, we may elect to, or governments may require us to (for example pursuant to the U.S. Defense Production Act), allocate our products in a way that adversely affects our regular operations and financial results, results in differential treatment of customers and/or adversely affects our reputation and customer relationships. Although we do not currently elect to, nor have we been required to, allocate our products in this way, there can be no assurance that we will not have to allocate our products in this way in the future. In addition, unpredictable increases in demand for certain of our products could exceed our capacity to meet such demand, which could adversely affect our financial results and customer relationships and result in negative publicity.

The duration and extent of the impact from the COVID-19 pandemic depends on future developments that cannot be accurately predicted at this time, such as the severity and transmission rate of the virus, the extent and effectiveness of containment actions and the impact of these and other factors on our employees, customers, suppliers and partners. Such impact on our business, cash flows and/or financial condition, and results of operations could be material.

To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this “Risk Factors” section.

We may face challenges in implementing our strategies for revenue growth in light of competitive challenges.

We face significant competition from a diverse and fragmented base of competitors, many of whom focus on specific regions, customers and/or specific product segments. Competitors range from smaller, specialized companies, which may be able to more quickly respond to customers’ specific needs, to large multinational companies who provide a full suite of products to research labs, which may have greater financial, marketing, operational and research and development resources than we do. Such greater resources may allow our competitors to respond more effectively with new, alternative or emerging technologies. In addition, consolidation trends in the pharmaceutical, biotechnology and diagnostics industries have created concentrated purchasing decisions for some customers, resulting in increased pricing pressure on us. Moreover, customers may believe that consolidated businesses are better able to compete as sole-source vendors and therefore, prefer to purchase from such businesses. New procurement channels, such as e-procurement and aggregators, may prove more attractive to customers through better delivery of products or blocking other channels where we have strength, and a failure by us to sufficiently engage and participate in these channels may lead to a loss of customer relationships. Failure to anticipate and respond to our competitors’ actions may impact our future sales and earnings, in particular failure to react to competitors strengthening their brand, marketing or customer experience may negatively impact our ability to attract and retain customers.

We are pursuing a number of strategies to maintain and improve our revenue growth, including:

24

Table of Contents

We may not be able to successfully implement these strategies, and these strategies may not result in the expected growth of our business. Failure to anticipate and respond to our competitors’ actions may adversely affect our business, financial condition and results of operations.

We must develop new products and enhance existing products, adapt to significant technological and innovative changes and respond to introductions of new products by competitors to remain competitive.

We sell our products in industries that are characterized by significant technological changes, frequent new product and technology introductions and enhancements and evolving industry standards. As a result, our customers’ needs continue to evolve. If we do not appropriately innovate and invest in new products or technologies, our product offerings may become less desirable in the markets we serve, and our customers could move to new technologies offered by our competitors or even choose to make products themselves. Though we believe customers in our markets display a significant amount of loyalty to a particular product, we also believe that because of the initial time investment required by many of our customers to reach a purchasing decision for a new product, it may be difficult to regain that customer once the customer purchases a product from a competitor. In order to maintain positive relationships with and maintain the trust of our customers, it is crucial that we are able to continue to innovate and create new products that directly support our customers’ research goals in a cost effective, timely and efficient manner. If our competitors are able react more directly and effectively to a customer’s specific demand, this could harm our ability to retain our customers, even if we manufacture a product that is responsive to their needs. There is also a risk that we may invest significant amounts of time and resources into a new product or product enhancement that fails to meet our high quality standards or does not perform in the way that was intended, which could adversely affect our business. Without the timely introduction of new products, services and enhancements to existing products or adequately meeting the changing demands of the industry, our offerings will likely become less competitive over time, in which case our competitive position, sales and operating results could suffer. Further, if a competitor were able to create a product or service that either eliminated or reduced the need for RUO antibodies and the related tools and solutions, or if there were an innovative development in the industry that made the use of antibodies no longer necessary for life science research, this could have a material adverse effect on our business and results of operations. Accordingly, we focus significant efforts and resources on the research, development and identification of new products and services that are attractive to our customers and gain acceptance in the markets we serve to further broaden our offerings. It can take significant time to identify an unmet customer need and develop a product to meet that need, and to the extent we fail to adequately anticipate or meet our customers’ needs or fail to obtain desired levels of market acceptance, our business, financial condition or results of operations could be adversely affected.

Our estimates of our addressable market include several key assumptions based on our industry knowledge, industry publications, third-party research and other surveys, which may be based on a small sample size and may fail to accurately reflect market opportunities. While we believe that our internal assumptions are reasonable, no independent source has verified such assumptions. Industry publications, research, surveys, studies and forecasts generally state that the information they contain has been obtained from sources believed to be reliable but that the accuracy and completeness of such information is not guaranteed. If any of our assumptions or estimates, or these publications, research, surveys or studies prove to be inaccurate, then the actual market for our products may be smaller than we expect, and as a result, our product revenue may be limited and our business, financial condition or results of operations could be adversely affected.

We may not successfully identify or integrate acquired businesses or assets into our operations or be able to fully recognize the anticipated benefits of businesses or assets that we acquire.

A key element of our business strategy is to complement our organic growth with acquisitions. We routinely explore acquiring other businesses and assets, and we have completed five acquisitions in the last two years, including: Marker Gene Technologies, Inc. in March 2020, the gene editing platform and oncology product portfolio of Applied StemCell, Inc. in January 2020, the proteomics and immunology businesses from Expedeon AG in January 2020, the entire live cell line and lysates portfolio of EdiGene Inc. in July 2019 and Calico Biolabs Inc. in January 2019. In addition, we have acquired minority interests in SomaServe Limited and BrickBio Inc.

However, we may be unable to identify or complete promising acquisitions for many reasons, including any misjudgment of the key elements of an acquisition, competition among buyers, the high valuations of businesses in our industry, the need for regulatory and other approvals, lack of internal resources to actively pursue all attractive opportunities and availability of capital. When we do identify and complete acquisitions, we may face financial, managerial and operational challenges, including diversion of management attention and resources needed for existing operations, difficulty with integrating acquired businesses, acquiring business that are not consistent with our long-term strategies, integration of different corporate cultures, increased expenses, potential dilution of our brand, assumption of unknown liabilities, indemnities, potential disputes with the sellers and the need to evaluate the financial systems of and establish internal controls for acquired entities. Further, we seek out acquisitions of companies that maintain the same high quality standards that we maintain, and if we misjudge or overestimate a company’s product quality standards, we may not be able to use these products or implement the strategies that were the primary reason for the acquisition, which would lead to a significant loss both financially and in time spent by our teams trying to integrate the product or implement the strategy. There can be no assurance that we will engage in any additional acquisitions or that we will be able to do so on terms that will result in any expected benefits.

In addition, our ability to realize the benefits we anticipate from our acquisition activities, including any anticipated sales growth, cost synergies and other anticipated benefits, will depend in large part upon whether we are able to integrate such businesses efficiently and effectively. Integration is an ongoing process, and we may not be able to fully integrate such businesses smoothly or successfully, and the process may take longer than expected. Further, the integration of certain operations and the differences in operational culture following such activity will continue to require the dedication of significant management resources, which may distract management’s attention from day-to-day business operations. There may also be unasserted claims or assessments that we failed or were unable to discover or identify in the course of performing due diligence investigations of target businesses. If we are unable to successfully integrate the operations of acquired businesses into our business, we may be unable to realize the sales growth, cost synergies and other anticipated benefits of such transactions, and our business, results of operations and cash flow could be adversely affected.

Our business may be harmed if our customers discontinue or spend less on research, development, production or other scientific endeavors.

A majority of our revenue is derived from consumers who are publicly funded through research grants. We have three primary categories of customers including: academic institutions, research institutions and pharmaceutical, biotechnology and diagnostic companies. Many factors, including public policy spending priorities, available resources and product and economic cycles, have a significant effect on the capital spending policies of these entities. For example, the United Kingdom’s withdrawal from the European Union has caused, and is likely to continue to cause, uncertainty in the European markets regarding the availability of public funding for research, which has had an indirect, but not significant, impact on our U.K. business. Fluctuations in the research and development budgets of our customers could have a significant effect on the demand for our products. Our customers determine their research and development budgets based on several factors, including the need to develop new products, continued availability of governmental and other funding, competition and the

26

Table of Contents

general availability of resources. If research and development budgets are reduced, or if any funding source were to influence customer selection toward another supplier, the impact could adversely affect our business, financial condition and results of operations.

Our business depends on our ability to use and access information systems, and any failure to successfully maintain these systems or implement new systems to handle our changing needs could materially harm our operations.

We depend on standardized procedures and multiple information systems, including our online platform and distribution and ERP systems, for our operations, customer service and quality and safety procedures. Furthermore, we rely on information technology systems to process, transmit, store and protect electronic information, including confidential customer, supplier, employee or other business information. Through our online platform, we collect and store confidential information that customers provide in order to, among other things, purchase products and services and register on our website.

We are currently updating our systems and processes by implementing Oracle Cloud ERP and other software solutions to replace our legacy IT systems on a scale reflecting the increased size, scope and complexity of our operations, and the process of migrating our legacy systems could disrupt our ability to timely and accurately process information. Further, any significant delay, failure, increase in costs of this project, or any issues in transitioning from our legacy systems to new information systems could have a negative impact on our ability to upgrade our information systems and may consequently adversely affect our business, financial condition and results of operations. We utilize commercially available third-party technology solutions, software and software systems with some proprietary configurations. We also store data using third-party cloud services. Our information systems are subject to damage or interruption from power outages, computer and telecommunications failures, computer viruses, security breaches, vandalism, catastrophic events, natural disasters, terrorist attacks, hackers and other security issues as well as human error. Given the age and lack of support of some of our legacy systems, these risks may be greater. If our information systems are damaged, fail to work properly or otherwise become unavailable, particularly in light of the COVID-19 pandemic, we may incur substantial costs to repair or replace them, and we may experience a loss of critical information, customer disruption and interruptions or delays in our ability to perform essential functions and implement new and innovative services. If the cloud service providers we use were to experience unplanned downtime, delays or other issues delivering data to our information technology systems, including due to increased usage during the COVID-19 pandemic, it could significantly and adversely impact business operations. A compromise of our information systems or those with which we interact could harm our reputation and expose us to regulatory actions and claims from customers and other persons, any of which could adversely affect our business, financial condition and results of operations.

In addition, we may not have the necessary resources to enhance existing information systems or implement new systems where necessary to handle our increasing volume and/or our changing needs, and we may experience unanticipated delays, complications and expenses in implementing and integrating our systems. Any interruptions in operations would adversely affect our ability to properly allocate resources and timely deliver our products, which could result in customer dissatisfaction. We currently rely on certain legacy systems that are no longer supported by the manufacturers, with only a small number of current employees able to maintain these systems. Any failure of these systems could have a significant business impact. The failure to successfully implement and maintain information systems could have an adverse effect on our ability to obtain new business, retain existing business and maintain or increase our sales and profit margins, any of which could adversely affect our business, financial condition and results of operations.

Cyber security risks and the failure to maintain the confidentiality, integrity and availability of our computer hardware, software and internet applications and related tools and functions, could result in damage to our reputation, data integrity and/or subject us to costs, fines or lawsuits under data privacy or other laws or contractual requirements.

The integrity and protection of our own data, and that of our customers and employees, is critical to our business. The regulatory environment governing information, security and privacy laws is increasingly demanding and continues to evolve. Implementing and maintaining compliance with applicable security and privacy regulations may increase our operating costs and/or adversely impact our ability to market our products and services to customers. Although our computer and communications hardware are protected through physical and software safeguards, they are still vulnerable to fire, storm, flood, power loss, earthquakes, telecommunications failures, physical or software break-ins, software viruses and similar events. These events could lead to the unauthorized access, disclosure and use of non-public information. We could be subject to risks caused by misappropriation, misuse, leakage, falsification, system malfunction or intentional or accidental release or loss of information maintained in our information systems and networks and those of our OEM suppliers. The techniques used by criminal elements to attack computer systems are sophisticated, change frequently and may originate from less regulated and remote areas of the world. As a result, we may not be able to address these techniques proactively or implement adequate preventative measures. We are also reliant on the quality of our training of employees to allow them to spot and appropriately respond to cyber security threats. We have been subject to a number of phishing attempts and require employees to remain vigilant to ensure that such attempts are unsuccessful. If our computer systems are compromised, we could be subject to fines, damages, litigation and enforcement actions, customers could curtail or cease using its applications, and we could lose trade secrets, the occurrence of which could harm our business.

If we are unable to maintain reliable information technology systems and appropriate controls with respect to global data privacy and security requirements and prevent data breaches, we may suffer regulatory consequences in addition to business consequences. As a global organization, we are subject to data privacy and security laws, regulations, and customer-imposed controls in numerous jurisdictions as a result of having access to and processing confidential, personal and/or sensitive data in the course of our business. There are numerous U.S. federal and state laws and regulations related to the privacy and security of personal information. In particular, regulations promulgated pursuant to the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) establish privacy and security standards that limit the use and disclosure of individually identifiable health information (known as “protected health information”) and require the implementation of administrative, physical and technological safeguards to protect the privacy of protected health information and ensure the confidentiality, integrity and availability of electronic protected health information. Determining whether protected health information has been handled in compliance with applicable privacy standards and our contractual obligations can require complex factual and statistical analyses and may be subject to changing interpretation. Although we take measures to protect sensitive data from unauthorized access, use or disclosure, our information technology and infrastructure may be vulnerable to attacks by hackers or viruses or breached due to employee error, malfeasance or other malicious or inadvertent disruptions. Any such breach or interruption could compromise our networks, and the information stored there could be accessed by unauthorized parties, manipulated, publicly disclosed, lost or stolen. Any such access, breach or other loss of information could result in legal claims or proceedings and liability under federal or state laws that protect the privacy of personal information, such as the HIPAA and the Health Information Technology for Economic and Clinical Health Act (“HITECH”) and may result in regulatory penalties. Notice of breaches must be made to affected individuals, the United States Department of Health and Human Services (“HHS”), and for extensive breaches, notice may need to be made to the media or state Attorneys General. Such a notice could harm our brand and reputation and adversely affect our ability to compete.

Additionally, the Gramm-Leach-Bliley Act of 1999 (along with its implementing regulations) (the “GLBA”) restricts certain collection, processing, storage, use and disclosure by covered companies of certain personal information, requires notice to individuals of privacy practices and provides individuals with certain rights to

28

Table of Contents

prevent the use and disclosure of certain non-public or otherwise legally protected information. The GLBA also imposes requirements regarding the safeguarding and proper destruction of personal information through the issuance of data security standards or guidelines. In addition, many U.S. states in which we operate now or may operate in the future have laws that protect the privacy and security of sensitive and personal information. Certain U.S. state laws may be more stringent or broader in scope, or offer greater individual rights, with respect to sensitive and personal information than federal, international or other state laws, and such laws may differ from each other, which may complicate compliance efforts. For example, the California Consumer Privacy Act of 2018 (the “CCPA”), which went into effect on January 1, 2020, imposes stringent data privacy and security requirements and obligations with respect to the personal information of California residents and households. Among other things, it requires covered companies to provide new disclosures to California consumers and provide such consumers new data protection and privacy rights, including the ability to opt-out of certain sales of personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for certain data breaches that result in the loss of personal information that may increase the likelihood of, and risks associated with, data breach litigation. The CCPA was amended in September 2018 and November 2019, and it is possible that further amendments will be enacted. It remains unclear how various provisions of the CCPA will be interpreted and enforced, and multiple states have enacted or are expected to enact similar laws. The effects of the CCPA and other similar state laws on our business are potentially significant and may require us to modify our data processing practices and policies and to incur costs and expenses in an effort to comply. State laws are changing rapidly, and there is discussion in U.S. Congress of a new federal data protection and privacy law to which we may be subject.

In Europe, laws, regulations and standards in many jurisdictions apply broadly to the collection, use, retention, security, disclosure, transfer and other processing of personal information. For example, in the European Economic Area (the “EEA”) and the United Kingdom, the collection and use of personal data is governed by the provisions of the General Data Protection Regulation (the “GDPR”). The GDPR came into effect in May 2018, superseding the European Union Data Protection Directive and imposing more stringent data privacy and security requirements on companies in relation to the processing of personal data of European Union data subjects. The GDPR, together with national legislation, regulations and guidelines of the European Union (the “EU”) member states and the United Kingdom govern the processing of personal data, impose strict obligations and restrictions on the ability to collect, use, retain, protect, disclose, transfer and otherwise process personal data. In particular, the GDPR includes obligations and restrictions concerning the consent and rights of individuals to whom the personal data relates, the transfer of personal data out of the EEA or the United Kingdom, security breach notifications and the security and confidentiality of personal data. The GDPR authorizes fines for certain violations of up to 4% of a company’s global annual revenue or €20 million, whichever is greater. Such fines are in addition to any civil litigation claims by customers and data subjects. European data protection authorities may interpret the GDPR and national laws differently and impose additional requirements, which contributes to the complexity of processing personal data in or from the EEA or United Kingdom. Guidance on implementation and compliance practices is often updated or otherwise revised. Further, while the United Kingdom enacted the Data Protection Act 2018 in May 2018 that supplements the GDPR and has publicly announced that it will continue to regulate the protection of personal data in the same way after the United Kingdom’s withdrawal from the European Union, the withdrawal has created uncertainty with regard to the future of regulation of data protection in the United Kingdom. Several other countries, such as China and Russia, have also passed laws that require personal data relating to their citizens to be maintained on local servers and impose additional data transfer restrictions, which could increase the cost and complexity of delivering our products and services.

We are also reliant on certain manual processes for collecting and processing data, and any failures in these processes or failure to handle the data collected in accordance with relevant regulations could lead to enforcement actions. Complying with all applicable laws, regulations, standards and obligations relating to data privacy, security and transfers may cause us to incur substantial operational costs or require us to modify our data processing practices and processes. Government enforcement actions can be costly and interrupt the regular operation of our business, and data breaches or violations of data privacy laws can result in significant fines,

reputational damage and civil lawsuits, any of which may adversely affect our business, financial condition and results of operations. We may not be able to respond quickly or effectively to regulatory, legislative and other developments, and these changes may in turn impair our ability to commercialize our products or increase our cost of doing business. In addition, if our practices are not consistent or viewed as not consistent with legal and regulatory requirements, including changes in laws, regulations and standards or new interpretations or applications of existing laws, regulations and standards, we may become subject to audits, inquiries, whistleblower complaints, adverse media coverage, investigations, loss of export privileges, severe criminal or civil sanctions or reputational damage. Any of the foregoing could have an adverse effect on our competitive position, business, financial condition, results of operations and prospects.

Our business may suffer if we do not successfully manage our current and potential future growth.

We have rapidly expanded our operations and anticipate expanding further as we pursue our growth strategies. Such expansion increases the complexity of our business and places a significant strain on our management, operations, technical systems, financial resources and internal control over financial reporting functions. Our current and planned personnel, systems, procedures and controls may not be adequate to support and effectively manage our future operations, especially as we employ personnel and maintain manufacturing facilities and distribution networks in several geographic locations. Across a range of business areas, we currently use systems and processes that are overly manual and reaching the limit of their scalability, and as we continue to grow and expand our business, these systems and processes will become outdated and will need to be replaced with more automated and up-to-date systems to maintain our growth. These systems and processes also interact with our inventory management and demand planning, and any failure in these systems or in the transition to updated systems may make it more likely we do not adequately anticipate and plan for business growth, potentially resulting in increased times for order fulfilment, order backlogs, reduced customer satisfaction and reduced order conversion. In addition, given the rapid growth of our business on these overly manual systems, there may be certain contractual terms, including royalties, that are not properly monitored. We may not be able to manage our expansion effectively, and failure to update and replace these systems and processes may adversely affect our reputation, business, financial condition and results of operations.

We are also continuously expanding our product portfolio, and establishing and developing these new products requires significant management time and attention. If these products do not achieve the anticipated success or require greater levels of time and investment to reach the expected levels, it could adversely affect our business, financial condition and results of operations. Failure to appropriately integrate new products and business lines into our existing operations and systems can also affect the success of these products, and failure to adequately anticipate and plan for this integration could affect the success of these products and may also negatively impact our existing product offerings.

Significant interruptions in our operations could harm our business, financial condition and results of operations.

Manufacturing, distribution, service and logistics problems can and do arise, particularly in light of the COVID-19 pandemic, and any such problems could have a significant impact on our business, financial condition and results of operations. Accordingly, any significant disruptions to the operations of our manufacturing or distribution centers or logistics providers for any reason, including labor relations issues, power interruptions, severe weather, fire or other circumstances beyond our control could cause our operating expenses to increase without coverage or compensation or seriously harm our ability to fulfill our customers’ orders or deliver products on a timely basis, or both. We must also maintain sufficient production capacity in order to meet anticipated customer demand, which carries fixed costs that we may not be able to offset if orders slow, which would adversely affect our operating margins. If we are unable to manufacture or source our products consistently, in sufficient quantities and on a timely basis, our sales, gross margins and our other operating results will be materially and adversely affected. Prompt shipment of our products is also very important to our business. We have experienced problems with or delays in our production, shipping and logistics capabilities, including as

30

Table of Contents

a result of the COVID-19 pandemic, that resulted in delays in our ability to ship finished products, and there can be no assurance that we will not encounter such problems in the future. If we experience significant delays in our manufacturing, shipping or logistics processes, this could cause disruption to our customers and damage our current and future customer relationships and may adversely affect our business. Such delays may also adversely impact our new product development. For example, if we were to lose one of our sites where new product development is undertaken, we may not be able to transfer or replicate that product development at another site, with the result of a loss of the time and financial costs of development of the new product. We also use small quantities of high-risk chemicals in the manufacture of certain of our products, which are subject to handling risks, and any disruption in our ability to source or appropriately store these chemicals could adversely affect our manufacturing operations.

In addition, as we are reliant on biological processes to manufacture many of our products, any loss or interruption to the systems that allow us to maintain optimal growth or storage conditions for our materials or products could lead to a loss of significant sections of our product portfolio, which may adversely affect our business, financial condition and results of operations. If a biological contaminant, such as bacteria, mold, yeasts, viruses or mycoplasma, were to affect our materials or our products, or if our materials or products were cross contaminated, it could affect the quality of our products, our inventory levels and disrupt our manufacturing and distribution processes, as well as those of our customers. We have quality control procedures in place to detect and correct such disruptions, but there can be no assurance that these procedures will always function properly. Any disruption to our manufacturing operations would disrupt our ability to serve our customers, which could have a material adverse effect on our reputation, business, financial condition and results of operations. Similarly, any contamination of our customers’ laboratories caused by our products could have a material adverse effect on our reputation, business, financial condition and results of operations.

Our offerings are highly complex, and, if our products do not satisfy applicable quality criteria, specifications and performance standards, we could experience lost sales, delayed or reduced market acceptance of our products, increased costs and damage to our reputation.

The products we offer are highly exacting and complex due to their biological nature and demanding customer specifications. Providing high-quality products in terms of specificity, sensitivity and consistency, together with extensive product validation data is a fundamental driver of customer loyalty and our reputation with life science researchers. Our operating results depend on our ability to execute and, when necessary, improve our global quality control systems, including our ability to effectively train and maintain our employees with respect to quality control. A failure of our global quality control systems could result in problems with facility operations or preparation or provision of defective or non-compliant products. In each case, such problems could arise for a variety of reasons, including equipment malfunction, failure to follow specific protocols and procedures, problems with critical materials and components, or environmental factors and damage to, or loss of, manufacturing operations. Such problems could affect production of a particular batch or series of batches of products, requiring the destruction of such products or a halt of facility production altogether.

Our success depends on our customers’ confidence that we can provide reliable, consistently high-quality products, which includes our ability to provide validated data to support our customers’ use of our products. We believe that customers in our target markets are likely to be particularly sensitive to our products failing to meet the specifications shown on our data sheets. Our reputation and the public image of our products and technologies may be impaired if our products fail to perform as expected or fail to meet applicable quality criteria, specifications or performance standards. High-quality reagents, for example, are necessary for critical research progress; unreliable reagents may impede researchers’ ability to reproduce experiments and can lead to wasted time and money. If our products experience, or are perceived to experience, a material defect or error, this could result in loss or delay of sales, damaged reputation, diversion of development resources and increased insurance or warranty costs, any of which could harm our business. These risks are amplified in respect of our new product lines as we implement appropriate quality control criteria. We are reliant to an extent on customer feedback on the quality of our products, and it may take additional time for new products to meet the desired

31

Table of Contents

quality. Such defects or errors could also result in our inability to timely deliver products to our customers, which could in turn cause disruptions to our customers’ ability to obtain results, narrowing the scope of the use of our products and ultimately hindering our or their success in relevant markets. Even after any underlying concerns or problems are resolved, any lingering concerns in our target markets regarding our technology, product defects or performance standards could continue to result in lost sales, delayed market acceptance and damaged reputation, among other things. If problems in preparation or manufacture of a product or failures to meet required quality standards for that product or other product defects are not discovered before such product is released to our customers, we may be subject to adverse legal or regulatory actions, including halting of manufacture and distribution, restrictions on our operations, civil sanctions, including monetary sanctions, and criminal actions. In addition, such problems or failures subject us to other litigation claims, including claims from our customers for reimbursement for the cost of lost or damaged materials. Our customers also require specific information regarding our products and their uses, and any inaccuracies in this information could lead to products being sold for the wrong uses and may result in our having to refund or replace the products in question. Any of the above problems may adversely affect our reputation, business, financial condition and results of operations.    

If we fail to maintain and enhance our brand and reputation, our business, results of operations and prospects may be materially and adversely affected.

We believe that maintaining and enhancing our brand and reputation are of significant importance to the success of our business. We work to set a very high standard for the quality of our products and our ethical business practices, and we believe that this has been crucial to our success. We have employed and will continue to employ different types of consumer experience and interaction touchpoints designed to gauge consumer satisfaction with our products, including our customer website, e-sales and digital marketing, and we also engage in rigorous product validation in order to continue to improve our product quality. We cannot assure you, however, that these activities will be successful or that we will be able to continue to maintain our brand and reputation as we expect. If our brand strength deteriorates, or if our brand is no longer associated with high-quality products, it could lead to fewer publication citations for our products, which could in turn further weaken our brand recognition and reputation. Customers often choose the most-cited brand or product, and if another brand were to overtake ours in frequency of citations, our business could be adversely affected. In addition, our competitors may increase the intensity of their consumer interactions or customer feedback processes, which may force us to increase our advertising spend to engage with our customer base and maintain brand and reputational awareness. Our ability to attract and retain customers is also influenced by our prominence in search engines. Any changes to our prominence in search engines, whether as a result of revised algorithms, improved search engine optimization by our competitors or failure to respond to changes in online activity may negatively impact our brand and reputation or to convert customer interactions into sales.

In addition, any negative publicity relating to our products or services, regardless of its veracity, could harm our brand and the perception of our brand in the market. With an increasing global focus on ethical business practices and good corporate behavior, and with such issues directly influencing consumer behavior, any failure to achieve or maintain the levels of corporate governance, social and environmental impact and corporate behaviors expected of us, including demonstrating dedication to the benefits of diversity, could negatively impact our brand and reputation. If our brand is harmed, we may not be able to gain new customers or continue to maintain positive relationships with our customers, and our business, prospects, financial condition and results of operations could be materially and adversely affected.

Part of our growth strategy is to increase direct customer interactions in multiple countries. Failure to anticipate and react to particular geographic requirements and sensitivities may have a negative impact on our brand and reputation, which may result in a decrease in sales or sales growth in such countries, which may adversely affect our business, prospects, financial condition and results of operations.

The loss of a significant number of customers or a reduction in orders from a significant number of customers could reduce our sales and harm our operating results.

Our operating results could be negatively affected by the loss of revenue from a significant number of our customers. Our sales are widely distributed, and many of our customers typically place smaller value orders in high volumes. We have other customers with whom we maintain close business relationships, working closely to build the specific custom tools they need, which will then become part of our product portfolio. These relationships often present larger commercial opportunities, and our operating results could be adversely affected by the loss of a significant number of these customers, particularly during the product development phase. For the year ended June 30, 2019, no single customer accounted for more than 5% of our revenue.

Though we often offer pricing and volume incentives, our customers are generally not obligated to purchase any fixed quantities of products, and they may stop placing orders with us at any time. If a significant number of customers purchase fewer of our products, defer orders or fail to place additional orders with us for any reason, our sales could decline, and our operating results may not meet our expectations. In addition, if those customers order our products, but fail to pay on time or at all, our liquidity and operating results could be adversely affected.

Our contracts generally do not contain minimum purchase requirements, and the majority of our sales are on a purchase order basis. Therefore, our sales are subject to changes in demand from our customers. The level and timing of orders placed by our customers vary for a number of reasons, including individual customer strategies, the introduction of new technologies, the desire of our customers to reduce their exposure to any single supplier and general economic conditions. If we are unable to anticipate and respond to the demands of our customers, if we have an inadequate supply of products, insufficient capacity in our sites or if we experience any disruptions to our supply chain or distribution network, we may lose customers. Alternatively, we may have excess inventory or excess capacity, and either of these factors may have a material adverse effect on our business, financial condition and results of operations.

Though we do generate a portion of our sales from long-term contracts, the majority of these contracts are non-exclusive and do not require a minimum purchase volume. This makes it difficult to estimate our customers’ demand for our products and our critical material and component needs. In addition, though we believe customers in our markets display a significant amount of loyalty to a particular product, we may not be able to renew a contract on favorable pricing terms if our competitors reduce their prices in order to procure business, or if a customer insists that we lower the price charged under the contract being renewed in order to retain the contract. In addition, if we enter into a contract with a customer on unfavorable terms, it may harm our ability to negotiate our future contracts with that customer or with other customers. The loss of sales obtained through long-term contracts or the reduced profitability of such sales could adversely affect our business, financial position and results of operations.

We are subject to risks associated with global operations.

We engage in business globally, with 63% and 61% of our catalogue revenue in the fiscal years ended June 30, 2020 and 2019, respectively, coming from outside the United States. Global operations subject us to a number of risks, many of which are exacerbated by the COVID-19 pandemic, including international economic, political and labor conditions; currency fluctuations; tax laws (including U.S. taxes on foreign subsidiaries); increased financial accounting and reporting burdens and complexities; unexpected changes in, or impositions of, legislative or regulatory requirements; failure of laws to protect intellectual property rights adequately; inadequate local infrastructure and difficulties in managing and staffing international operations; delays resulting from difficulty in obtaining import or export licenses; limitations on repatriation of funds; tariffs, quotas and other trade barriers and restrictions; transportation delays; operating in locations with a higher incidence of corruption and fraudulent business practices; limitations on our ability to enforce legal rights and remedies with third parties and other factors beyond our control, including terrorism, war, natural disasters, climate change and diseases.

Overall demand for our products could be reduced as a result of a global economic recession or political unrest, especially in areas such as healthcare, education and research. Customers or suppliers may experience cash flow problems, particularly in light of the COVID-19 pandemic and related response measures, and as a result, customers have and may continue to modify, delay or cancel plans to purchase our products. Any inability of current and/or potential customers to purchase and/or pay for our products due to, among other things, declining economic conditions as a result of inflation, rising interest rates, changes in spending patterns and the effects of governmental initiatives to manage economic conditions may have a negative impact on our financial condition and results of operations.

The U.S. administration has indicated an intention to ask Congress to make significant changes, replacement or elimination of the Patient Protection and Affordable Care Act, and government negotiation/regulation of drug prices paid by government programs. Changes in U.S. social, political, regulatory and economic conditions or laws and policies governing the healthcare system and drug prices, foreign trade, manufacturing and development and investment in the territories and countries where we or our customers operate could adversely affect our business and our operating results.

The application of laws and regulations implicating global transactions is often unclear and may at times conflict. Compliance with these laws and regulations may involve significant costs or require changes in our business practices that result in reduced revenue and profitability. For example, we may be exposed to any changes in national or international regulations governing the transport of biological products across borders. Non-compliance could also result in fines, damages, criminal sanctions, prohibited business conduct and damage to our reputation. We incur additional legal compliance costs associated with our global operations and could become subject to legal penalties in foreign countries if we do not comply with local laws and regulations, which may be substantially different from those in the United Kingdom or United States. Any such non-compliance, even if prohibited by our internal policies, could have an adverse effect on our business and result in significant fines or penalties.

If relations between China and the United States deteriorate, our business in the United States and China could be materially and adversely affected.

The relationship between China and the United States is subject to periodic tension. Changes in political conditions in the United States and China and changes in the state of China-U.S. relations are difficult to predict and could adversely affect our business. Most recently, on August 6, 2020, the President of the United States signed an executive order that prohibited, beginning 45 days after the date of the order, to the extent permitted under applicable law: any transaction related to WeChat by any person, or with respect to any property, subject to the jurisdiction of the United States, with Tencent Holdings Ltd., Shenzhen, China or any subsidiary of that entity. Our subsidiary in China has historically used social media platforms like WeChat, and during the COVID-19 pandemic it increased its use of WeChat as a service channel to ensure that customer service levels were maintained. Moreover, the U.S. administration has called for substantial changes to trade agreements and is imposing significant increases on tariffs on goods imported into the United States, particularly from China. Other countries have responded similarly, with tariffs on goods entering their countries. We currently sell products in China and have invested, and will continue to invest, in providing localized product support, operations and technology to better serve customers in China, and if the Chinese government makes any changes to its laws or policy concerning foreign ownership of companies or assets located within China, or imposes any significant increases on tariffs on goods imported into or out of China, it could have a significant impact on our business and financial results.

In addition, because of our continuing focus on strategic investment into providing more products to the life science and academic research market in China, any deterioration in political or trade relations might cause a public perception in the United States or elsewhere that may cause our products to become less attractive. We cannot predict what effect any changes in China-U.S. relations may have on our ability to access capital or effectively operate in China, which could have a material adverse effect on our business and results of operations.

The United Kingdom’s withdrawal from the European Union may have a negative effect on global economic conditions, financial markets and our business.

We are a multinational company headquartered in the United Kingdom with worldwide operations, including significant business operations in Europe. Following a national referendum and enactment of legislation by the government of the United Kingdom, the United Kingdom formally withdrew from the European Union on January 31, 2020 and entered into a transition period during which it will continue its ongoing and complex negotiations with the European Union relating to the future trading relationship between the parties. Significant political and economic uncertainty remains about whether the terms of the relationship will differ materially from the terms before withdrawal, as well as about the possibility that a so-called “no deal” separation will occur if negotiations are not completed by the end of the transition period. To prepare for the United Kingdom’s withdrawal, we set up a European distribution hub in The Netherlands to ensure consistent deliveries to our European customers, but there can be no assurance that the uncertainty regarding the United Kingdom’s withdrawal could continue to have an adverse effect on our business.

These developments, or the perception that any of them could occur, have had and may continue to have a material adverse effect on global economic conditions and the stability of global financial markets and could significantly reduce global market liquidity and restrict the ability of key market participants to operate in certain financial markets. Asset valuations, currency exchange rates and credit ratings have been and may continue to be subject to increased market volatility. Lack of clarity about future United Kingdom laws and regulations as the United Kingdom determines which European Union laws to replace or replicate, including free trade agreements, tax and customs laws, intellectual property rights, environmental, health and safety laws and regulations, immigration laws, employment laws and transport laws could increase costs, disrupt supply chains, depress economic activity and restrict our access to capital. Any of these factors could have a material adverse effect on our business, financial condition and results of operations.

As a multinational corporation, we are exposed to fluctuations in currency exchange rates, which could adversely affect our cash flows and results of operations.

International markets contribute a substantial portion of our revenue, and we intend to continue expanding our presence in these regions. The exposure to fluctuations in currency exchange rates takes on different forms. International revenue and costs are subject to the risk that fluctuations in exchange rates could adversely affect our reported revenue and profitability when translated into pounds sterling for financial reporting purposes. The majority of our revenue is denominated in U.S. dollars, and our costs are primarily in British pounds sterling. These fluctuations could also adversely affect the demand for products and services provided by us. As a multinational corporation, our businesses occasionally invoice third-party customers in currencies other than the one in which they primarily do business (the “functional currency”). Movements in the invoiced currency relative to the functional currency could adversely impact our cash flows and our results of operations. As our international sales grow, exposure to fluctuations in currency exchange rates could have a larger effect on our financial results. In the fiscal year ended June 30, 2020, currency translation had a favorable effect of £3.7 million on revenue due to the strengthening of the pound sterling relative to other currencies in which we sell products and services. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Quantitative and Qualitative Disclosure about Market Risk—Currency Risk.”

We are subject to product liability and other claims in the ordinary course of business.

Our business involves risk of product liability, claims related to providing incorrect product information at the time of purchase and other claims in the ordinary course of business arising from the products that we source from various manufacturers or produce ourselves. Furthermore, there may be product liability risks that are unknown or which become known in the future. Substantial, complex or extended litigation on any claim could cause us to incur significant costs and distract our management. For example, lawsuits by governmental authorities, employees, shareholders, suppliers, collaborators, distributors, customers, competitors or others could

35

Table of Contents

be very costly and substantially disrupt our business. Our exposure to such claims may increase as we seek to increase the geographic scope of our sourcing and sales activities and to the extent that we expand our manufacturing operations. We maintain insurance policies and in some cases, our suppliers, customers and predecessors of acquired companies have indemnified us against certain claims. We cannot assure you that our insurance coverage or indemnification agreements will be available in all pending or any future cases brought against us. Furthermore, our ability to recover under any insurance or indemnification arrangements is subject to the terms and conditions of such insurance or indemnification agreement, as well as the financial viability of our and such third parties’ insurers, as well as legal enforcement under the local laws governing these arrangements. Insurance coverage in general or coverage for certain types of liabilities, such as product liability in developing markets, may not be readily available for purchase or cost-effective for us to purchase. Furthermore, many of our insurance policies are subject to deductibles and retentions. Accordingly, we could be subject to uninsured and unindemnified future liabilities requiring us to provide additional reserves to address such liabilities. An unfavorable result in a case for which adequate insurance or indemnification is not available could adversely affect our business, financial condition and results of operations.

We are also involved in various disputes, litigation and regulatory matters incidental to and in the ordinary course of our business, including employment matters, commercial disputes, government compliance matters, environmental matters, and other matters arising out of the normal conduct of our business. Where merited, we will vigorously defend ourselves in such matters. While the impact of this litigation has or may be immaterial, there can be no assurance that the impact of the pending and any future claims will not be material to our business, financial condition or results of operations in the future.

Our business, financial condition and results of operations depend upon the availability of critical materials and components.

Our operations depend upon our ability to obtain high-quality third-party products and materials meeting our specifications and other requirements at reasonable prices, including various components, storage and growth media and other materials. Our ability to maintain an adequate supply of such critical materials and components could be impacted by the availability and price of those materials and maintaining relationships with suppliers. While we may seek to minimize the impact of price increases and potential shortages by, among other things, entering into long-term supply agreements, increasing our own prices and implementing cost-saving measures, our earnings and cash flows could be adversely affected in the event these measures are insufficient to cover our costs. Moreover, while we aim to maintain a large network of product suppliers, we are unable to predict any interruption or disruption in service from our key suppliers, particularly in light of the COVID-19 pandemic. Any interruption or disruption in service from particular suppliers of components and materials means that interruptions or stoppages in such deliveries could adversely affect our operations until arrangements with alternate suppliers, to the extent any alternate suppliers acceptable to us and, if applicable, to our customers, even exist. If this occurs, we could expend substantial expense and time in re-establishing relationships with third-party suppliers that meet the appropriate quality, cost and regulatory requirements needed for commercially viable manufacture of our products or in re-designing our products to incorporate different components and materials that are available from third-party suppliers. If we are unable to obtain the materials we need at reasonable prices or at all, we may not be able to produce certain of our products at a marketable price or at all. If our supply of materials and components is adversely affected, including as a result of the COVID-19 pandemic, we could impact our customers’ ability to conduct their research, damage our relationship with current and prospective customers and our operating results and financial condition could be adversely affected.

Moreover, we are dependent upon the ability of our suppliers to provide materials and components that meet our specifications, quality standards, other applicable criteria and delivery schedules. Our suppliers’ failure to provide expected materials or components that meet such criteria could adversely affect production schedules and contract profitability.

36

Table of Contents

The continued supply of high-quality third-party products and materials from our suppliers is subject to a number of risks, including:

If we experience problems with suppliers, we may not be able to find acceptable alternatives, and any such alternatives could result in increased costs for us and possible forward losses on certain contracts. Even if acceptable alternatives are found, the process of locating and securing such alternatives might be disruptive to our business, might lead to termination of our supply agreements with our customers and might disrupt the operations of our customers leading to potential claims, any of which could adversely affect our business, financial condition and results of operations.

Our business, financial condition and results of operations depend upon maintaining our relationships with suppliers.

Our ability to sustain our gross margins has been, and will continue to be, dependent in part upon our ability to obtain favorable terms from our suppliers. These terms may change from time to time, and such changes could adversely affect our gross margins over time. In addition, our results of operations and cash flows could be adversely impacted by the acceleration of payment terms to our suppliers and/or the imposition of more restrictive credit terms and other contractual requirements. Further, if for any reason we enter into a contract with a supplier on unfavorable terms, it may harm our ability to negotiate our future contracts with that supplier or with other supplier.

Some of our competitors are increasing their manufacturing operations both internally and through acquisitions of manufacturers, including manufacturers that supply products to us. In addition, we manufacture certain products that may compete directly with products we source from our suppliers. To date, we have not experienced an adverse impact on our ability to continue to source products from manufacturers that have been vertically integrated or otherwise compete with us, although there is no assurance that we will not experience such an impact in the future.

The loss of one or more of our large suppliers, including as a result of consolidation, a material reduction in their supply of products or provision of services to us, extended disruptions or interruptions in their operations or material changes in the terms we obtain from them, could have a material adverse effect on our business, financial condition and results of operations.

We are highly dependent on our management and employees. Competition for our employees is intense, and we may not be able to attract and retain the highly skilled employees that we need to support our business and our intended future growth.

Our success largely depends on the skills, experience and continued efforts of our management, including our Chief Executive Officer and our senior leadership. The replacement of certain members of our global leadership team would likely involve the expenditure of significant time and financial resources, and the loss of any such individual may significantly delay or prevent the achievement of our business objectives. As we continue to grow, our success also depends on our ability to attract, motivate and retain highly qualified individuals who will also fit within the Abcam culture. Competition for senior management and other personnel in our industry is intense, and the pool of suitable candidates is limited. If qualified personnel become scarce or difficult to attract or retain in our industry for compensation-related or other reasons, we could experience higher labor, recruiting or training costs. Further, new hires may require significant training and time before they achieve full productivity and may not become as productive as we expect. The failure to attract, retain and properly motivate members of our senior management team and other employees, to find suitable replacements for them in the event of death, illness or their desire to pursue other professional opportunities, or to maintain our corporate culture as we continue to grow, could have a negative effect on our operating results.

We are also reliant on contractors in certain key operational and leadership roles. While we are seeking to replace such contractors with permanent employees, until such appointments are made, we are subject to the risk inherent in the use of contractors, including the risk that they accept an alternative engagement or that they are not sufficiently motivated, incentivized or aligned to our commercial objectives.

We may be required to record a significant charge to earnings if our goodwill and other amortizable intangible assets or other investments become impaired.

We are required under IFRS to test goodwill for impairment at least annually and to review our goodwill, amortizable intangible assets and other investments, including those acquired through acquisition activity, for impairment when events or changes in circumstance indicate the carrying value may not be recoverable.

Factors that could lead to impairment of goodwill, amortizable intangible assets and other investments, including those acquired through acquisitions, include significant adverse changes in the business climate and actual or projected operating results and declines in the financial condition of our business. For example, for the fiscal year ended June 30, 2020, we experienced an impairment charge of £14.9 million in respect of the full impairment of the acquisition intangible in respect of AxioMx in vitro monoclonal antibody production technology (AxioMx acquired technology) and subsequent post acquisition expenditure is capitalized. This arose following an appraisal of the ability to utilize at scale this technology, whereby, although technical feasibility remains valid, the challenges to realize material commercial returns have resulted in the conclusion not to further pursue active development and substantive utilization of this specific acquired technology. Additionally, in the fiscal year ended June 30, 2019, we experienced an impairment of software assets under construction of £12.8 million as a result of changes in the scope and nature of our ERP program and the corresponding usability of historical work performed on certain outstanding modules. We may be required in the future to record additional charges to earnings if our goodwill, amortizable intangible assets or other investments become impaired. Any such charge would adversely impact our financial results.

Our reputation, ability to do business and results of operations may be impaired by improper conduct by any of our employees, agents or business partners.

We cannot provide assurance that our internal controls and compliance systems will always protect us from acts committed by employees, agents or business partners of ours (including third-party suppliers, distributors or of businesses we acquire or partner with) that would violate U.S. and/or other national laws, including the laws governing payments to government officials, bribery, fraud, kickbacks and false claims, pricing, sales and marketing practices, conflicts of interest, competition, export and import compliance, money laundering and data privacy. In particular, the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and similar anti-bribery laws

38

Table of Contents

in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business, and we operate in many parts of the world that have experienced corruption to some degree. All of our employees are required to undertake regular training on topics like anti-bribery, corruption and GDPR legislation, among others. Additionally, we require our suppliers and distributors to sign up and abide by our Supplier and Distributor Codes of Conduct; however, there can be no assurance that our employees, suppliers and distributors will not engage in improper actions. Any such improper actions or allegations of such acts could damage our reputation and subject us to civil or criminal investigations in the United States and in other jurisdictions, and any related shareholder lawsuits could lead to substantial civil and criminal, monetary and nonmonetary penalties and could cause us to incur significant legal and investigatory fees. In addition, a government may seek to hold us liable as a successor for violations committed by companies in which we invest or that we acquire. We also rely on our suppliers to adhere to our supplier standards of conduct, and material violations of such standards of conduct could occur that could have a material effect on our business, reputation, financial condition and results of operations.

The indemnification provisions of acquisition agreements by which we have acquired companies or businesses may not fully protect us, and we may face unexpected liabilities.

Certain of the acquisition agreements by which we have acquired companies or businesses require the former owners to indemnify us against certain liabilities related to the operation of the company or business before we acquired it. In most of these agreements, however, the liability of the former owners is limited, and certain former owners may be unable to meet their indemnification responsibilities. While we have limited escrow and retention agreements in place relating our acquisitions, these may not be enough to cover our exposure if a significant liability arose in connection with any acquisition agreement. We cannot assure you that these indemnification provisions, escrow agreements and retention agreements will protect us fully or at all, and as a result we may face unexpected liabilities that adversely affect our business, financial condition and results of operations.

Certain aspects of our business rely on relationships with collaborative partners, distributors and other third parties for development, supply and marketing of certain products and potential products, and such collaborative partners or other third parties could fail to perform sufficiently.

We believe that success in penetrating certain geographic markets depends in part on our ability to develop and maintain relationships with key distributors. Relying on distribution relationships is risky because, among other things, our distributors may: not devote sufficient resources to the sales of our products; fail to obtain approvals necessary to distribute our products; be acquired by other companies and terminate our distribution agreements or become insolvent; or decline to renew existing agreements on acceptable terms. Because these and other factors may be beyond our control, the distribution of our products in certain jurisdictions may be delayed or otherwise adversely affected. If we or any of our distributors terminate a distribution agreement, we may be required to devote additional resources to commercialization and distribution, which could adversely affect our business, financial condition and results of operations.

Changes in our tax rates, unavailability of certain tax credits or reliefs or exposure to additional tax liabilities or assessments could affect our profitability, and audits by tax authorities could result in additional tax payments for prior periods.

We are affected by various U.S. and non-U.S. taxes, including direct and indirect taxes imposed on our global activities, such as corporate income, withholding, customs, excise, value-added, sales and other taxes. Significant judgment is required in determining our provisions for taxes, and there are many transactions and calculations where the ultimate tax determination is uncertain.

The amount of income tax we pay is subject to ongoing audits by U.S. federal, state and local tax authorities and by non-U.S. tax authorities. If audits result in payments or assessments different from our reserves, our future results may include unfavorable adjustments to our tax liabilities, and our financial statements could be adversely affected. Any further significant changes to the tax system in the United States or in other jurisdictions (including changes in the taxation of international income as further described below) could adversely affect our business, financial condition and results of operations.

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 U.K. corporation tax. Broadly, RDECs provide a tax credit currently equal to 13% of “qualifying research and development expenditure” made from April 1, 2020 (the rate was previously 12% of qualifying research and development expenditure made from January 1, 2018 to March 31, 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 U.K. 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.

We also benefit from the U.K.’s “patent box” regime, which allows certain profits attributable to revenues from patented products (and other qualifying income) to be taxed at an effective corporation tax rate of 10%.

If, however, there are unexpected adverse changes to the RDEC scheme or the “patent box” regime, or for any reason we are unable to qualify for such advantageous tax legislation, then our business, results of operations and financial condition may be adversely affected.

Changes in tax law relating to multinational corporations could adversely affect our tax position.

The U.S. Congress, government agencies in non-U.S. jurisdictions where we and our affiliates do business, and the Organization for Economic Cooperation and Development (“OECD”) have recently focused on issues related to the taxation of multinational corporations. One example is in the area of “base erosion and profit shifting,” where profits are claimed to be earned for tax purposes in low-tax jurisdictions, or payments are made between affiliates from a jurisdiction with high tax rates to a jurisdiction with lower tax rates. The OECD has released several components of its comprehensive plan to create an agreed set of international rules for addressing base erosion and profit shifting.

As we operate in numerous taxing jurisdictions, the application of tax laws can be subject to diverging and sometimes conflicting interpretations by tax authorities of these jurisdictions. It is not uncommon for taxing authorities in different countries to have conflicting views, for instance, with respect to, among other things, whether a permanent establishment exists in a particular jurisdiction, the manner in which the arm’s length standard is applied for transfer pricing purposes, or with respect to the valuation of intellectual property. For example, if the taxing authority in one country where we operate were to reallocate income from another country where we operate, and the taxing authority in the second country did not agree with the reallocation asserted by the first country, we could become subject to tax on the same income in both countries, resulting in double taxation. If taxing authorities were to allocate income to a higher tax jurisdiction, subject our income to double taxation or assess interest and penalties, it could increase our tax liability, which could adversely affect our financial position and results of operations.

Due to the potential for changes to tax laws and regulations or changes to the interpretation thereof (including regulations and interpretations pertaining to recent tax reform in the United States), the ambiguity of tax laws and regulations, the subjectivity of factual interpretations, uncertainties regarding the geographic mix of earnings in any particular period, and other factors, our estimates of effective tax rate and income tax assets and liabilities may be incorrect and our financial statements could be adversely affected. The impact of the factors referenced in the first sentence of this paragraph may be substantially different from period-to-period.    

The application of indirect taxes could adversely affect our business and results of operations.

The application of indirect taxes, such as sales and use tax, value-added tax, provincial taxes, goods and services tax, business tax and gross receipt tax, to our business is a complex and evolving issue. Significant

judgment is required to evaluate applicable tax obligations. As a result, amounts recorded may be subject to adjustments by the relevant tax authorities. In many cases, the ultimate tax determination is uncertain because it is not clear how new and existing statutes might apply to our business. A number of jurisdictions globally have introduced (or are looking to introduce) additional reporting, record-keeping or value-added tax (or similar taxes) calculation, collection and remittance obligations on businesses like ours that are engaged in ecommerce.

Further, in the United States, states are able to tax their residents on remote sales. Following the U.S. Supreme Court’s decision in 2018 in South Dakota v. Wayfair, a U.S. state may require by way of “economic nexus laws” an online seller to collect sales taxes imposed by that state, even if the seller has no physical presence in that state, thus permitting a wider enforcement of such sales tax collection requirements against non-U.S. companies that have historically not been responsible for state or local tax collection unless they had physical presence in the U.S. customer’s state. Such legislation could require us to incur substantial costs in order to comply, including costs associated with legal advice, tax calculation, collection, remittance and audit requirements, which could make selling in such markets less attractive and could adversely affect our business.

We are required to comply with a wide variety of laws and regulations and are subject to regulation by various federal, state and foreign agencies.

The vast majority of our products are marketed and sold as being for research use only, and as such, they are not generally subject to the extensive laws and regulations that would apply if our products were to marketed and sold for diagnostic or therapeutic use.

RUO products are regulated by the U.S. Food and Drug Administration (the “FDA”) as medical devices, and include in vitro diagnostic products in the laboratory research phase of development that are being shipped or delivered for an investigation that is not subject to the FDA’s investigational device exemption requirements. Although medical devices are subject to stringent FDA oversight, products that are intended for RUO and are labeled as RUO are exempt from compliance with most FDA requirements, including premarket clearance or approval, manufacturing requirements, and others. A product labeled RUO but which is actually intended for clinical diagnostic use may be viewed by the FDA as adulterated and misbranded under the Federal Food, Drug, and Cosmetic Act (“FDCA”), and subject to FDA enforcement action. The FDA has indicated that when determining the intended use of a product labeled RUO, the FDA will consider the totality of the circumstances surrounding distribution and use of the product, including how the product is marketed and to whom. The FDA could disagree with our assessment that our products are properly marketed as RUOs, or could conclude that products labeled as RUO are actually intended for clinical diagnostic use and could take enforcement action against us, including requiring us to stop distribution of our products until we are in compliance with applicable regulations, which would reduce our revenue, increase our costs and adversely affect our business, prospects, results of operations and financial condition. In the event that the FDA requires us to obtain marketing authorization of our RUO products in the future, there can be no assurance that the FDA will grant any clearance or approval requested by us in a timely manner, or at all.

In the event that the applicable laws and regulations were to change such that our products were subject to greater regulatory control, it could have a significant impact on our ability to market and sell our products and could require us to spend significant amounts to ensure and monitor compliance with such laws and regulations such that our business, financial condition and results of operations could be adversely affected. Similarly, if we fail to appropriately market and sell our products as being for research use only, we may be found to be selling products for diagnostic use and in breach of the appropriate laws and regulations. Though we are careful to ensure that our products are clearly identified as being for research use only and have processes in place to ensure we are not selling our products to customers who may intend to use our products other than for research, including for diagnostic use, we cannot be certain that our customers will not use our products for purposes other than those for which they are manufactured, identified and marketed.

Generally, we are subject to various local, state, federal, foreign and transnational laws and regulations, which include the requirements of the FDA, the U.S. Department of Health and Human Services (the “HHS”)

41

Table of Contents

and other comparable agencies and, in the future, any changes to such laws and regulations could adversely affect us. In particular, for a very small number of our products which are regulated as non-RUO medical devices, we are subject to laws and regulations concerning current good manufacturing practices and certain other requirements applicable to medical devices. We also maintain certain quality management systems accreditations at our facilities in Cambridge, United Kingdom, Hangzhou, China (ISO9001) and Burlingame, California (ISO13485). Our subsidiaries may be required to register for permits and/or licenses with, and may be required to comply with the laws and regulations of, the FDA, the HHS, foreign agencies and/or comparable state agencies as well as certain accrediting bodies depending upon the type of operations and location of product distribution, manufacturing and sale. The manufacture, distribution and marketing of certain of our products are subject to extensive ongoing regulation by the FDA and other equivalent local, state, federal and non-U.S. regulatory authorities. In addition, we are subject to inspections by these regulatory authorities. Failure by us or by our customers to comply with the requirements of these regulatory authorities or quality accreditation agencies, including without limitation, remediating any inspectional observations to the satisfaction of these regulatory authorities, could result in warning letters, product recalls or seizures, monetary sanctions, injunctions to halt manufacture and distribution, restrictions on our operations, civil or criminal sanctions or withdrawal of existing or denial of pending approvals, including those relating to products or facilities. In addition, such a failure could expose us to contractual or product liability claims, contractual claims from our customers, as well as ongoing remediation and increased compliance costs, any or all of which could be significant.

We are also subject to a variety of federal, state, local and international laws and regulations that govern, among other things, the importation and exportation of products, animal welfare, the handling, transportation and manufacture of substances that could be classified as hazardous, laws governing government contracts and our business practices such as anti-corruption and antitrust laws. Although we believe that we comply in all material respects with applicable laws and regulations, there can be no assurance that a regulatory agency or tribunal would not reach a different conclusion concerning the compliance of our operations with applicable laws and regulations. In addition, there can be no assurance that we will be able to maintain or renew existing permits, licenses or other regulatory approvals or obtain, without significant delay, future permits, licenses or other approvals needed for the operation of our businesses. Furthermore, loss of a permit, license or other approval in any one portion of our business may have indirect consequences in other portions of our business if regulators or customers, for example, cease doing business with such other portion due to fears that such loss is a sign of broader concerns about our ability to deliver products or services of sufficient quality.

Any noncompliance by us with applicable laws and regulations or the failure to maintain, renew or obtain necessary permits and licenses could have an adverse effect on our business, financial condition and results of operations. Failure to comply with these laws and regulations can lead to agency action, including warning letters, product recalls, product seizures, monetary sanctions, injunctions to halt manufacturing or distribution, restrictions on our operations, withdrawal of existing or denial of future approvals, permits or registrations, including those relating to products or facilities and civil and criminal sanctions. To the extent these agencies were to take enforcement action, such action may be publicly available, and such publicity could harm our ability to sell these regulated products globally and may harm our reputation. In addition, such actions could limit the ability of our customers to obtain regulatory clearance or approval for their products in the United States or abroad and/or our customers may incur significant costs in obtaining or maintaining such regulatory clearances or approvals in the United States or abroad. In addition, any such failure relating to the products we provide exposes us to direct and third-party product liability claims as well as contractual claims from our customers, including claims for reimbursement for lost or damaged products, as well as potential recall liability, which could be significant. Customers may also claim loss of profits due to lost or delayed sales, although our direct contracts with end customers typically place limits on such claims. There can be no assurance that any such contractual limitation will be applicable or sufficient or fully enforced in any given situation.

Risks Relating to our Intellectual Property

If we are unable to obtain and maintain patent protection for our technology, products and potential products, or if the scope of the patent protection obtained is not sufficiently broad, we may not be able to compete effectively in our markets.

We rely, and will continue to rely, upon a combination of patents, trade secret protection and confidentiality agreements to protect the intellectual property related to our proprietary technologies, products and potential product. Our success depends in part on our ability to secure and maintain patent protection in the United States and other countries with respect to our technology, current products and potential products, and any future potential products and technology we may develop. We seek to protect our proprietary position by filing or collaborating with our licensors to file patent applications in the United States and abroad related to our proprietary technologies, products and potential products.

The patent prosecution process is expensive, time consuming and complex, and we may not be able to file, prosecute, maintain, defend, enforce or license all necessary or desirable patents at a reasonable cost or in a timely manner in all desirable jurisdictions. As a result, we may not be able to prevent competitors or other third parties from developing and commercializing competitive products in all such fields and jurisdictions.

It is possible that we will fail to identify patentable aspects of our research and development output or fail to take the necessary steps to seek patent protection before it is too late to obtain patent protection. We may not have the right to control the preparation, filing, and prosecution of patent applications, or to maintain the rights to patents licensed from third parties. Therefore, these patents and patent applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. The patent applications that we own or in-license may fail to result in issued patents with claims that cover our relevant proprietary products and technology, including current products, potential products, and any future potential products we may develop in the United States or in other foreign countries, in whole or in part. Our existing patents may have issued with claims that fail to cover our relevant proprietary products and technology, including current products, potential products and any future potential products we may develop in the United States or in other foreign countries, in whole or in part. Alternately, our existing patents and any future patents we obtain may not be sufficiently broad to prevent others from using our technology or from developing competing products and technologies. Patents may not be granted for a number of reasons, including known or unknown prior art, deficiencies in the patent application or the lack of novelty of the underlying invention or technology. In addition, publications of discoveries in scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases, not at all. Therefore, we cannot be certain that we or our licensors were the first to make the inventions claimed in our owned or licensed patents or pending patent applications or that we or our licensors were the first to file for patent protection of such inventions.

Even if patents do successfully issue and even if such patents cover our current products, current potential products and any future potential products we may develop, third parties may challenge their validity, ownership, enforceability or scope thereof, which may result in such patents being narrowed, invalidated, or held unenforceable or circumvented. We may become involved in proceedings challenging our owned or licensed patent rights, including, but not limited to, opposition, derivation, reexamination, inter partes review, post grant review or interference. Any successful challenge to these patents or any other patents owned by or licensed to us could deprive us of rights necessary for the successful commercialization of any of our products and may result in loss of patent rights or freedom to operate, loss of exclusivity, or patent claims being narrowed, invalidated or held unenforceable, any of which could limit our ability to stop others from using or commercializing similar or identical technology and products, or could limit the duration of the patent protection of our technology, products and potential products. Such proceedings also may result in substantial costs and require significant time from our management and employees, even if the eventual outcome is favorable to us. In addition, the issuance of a patent does not give us the right to practice the patented invention. Third parties may have blocking patents that

43

Table of Contents

could prevent us from marketing our products, if approved, or practicing our own patented technology. Our competitors may also be able to circumvent our patents by developing similar or alternative potential products in a non-infringing manner.

The patent position of life sciences companies can be uncertain, involves complex legal, scientific and factual questions, and is characterized by the existence of large numbers of patents and litigation based on allegations of patent or other intellectual property infringement, misappropriation, violation or invalidity. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are uncertain. If the patent applications we hold or have in-licensed with respect to our technology products and potential products fail to issue, if the validity, breadth or strength of protection of our patents and patent applications with respect to our technology, products and potential products is threatened or if they fail to provide meaningful exclusivity for any of our current or future technology products and potential products, it could dissuade companies from collaborating with us, encourage competitors to develop competing products or technologies and threaten our ability to commercialize future potential products. Any such outcome could harm our business.

In addition, we may in the future be subject to claims by former employees, consultants or other third parties asserting an ownership right in our owned or licensed patents or patent applications. An adverse determination in any such submission or proceeding may result in loss of exclusivity or freedom to operate or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar products, potential products or technology, without payment to us, or could limit the duration of the patent protection covering our products, potential products and technology. Such challenges may also result in our inability to develop, manufacture or commercialize our products, potential products and technologies without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our owned or licensed patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future products, potential products or technologies. Any of the foregoing could have an adverse effect on our competitive position, business, financial condition, results of operations and prospects.

Variability and developments in patent laws or patent jurisprudence could diminish the value of patents in general, thereby impairing our ability to protect our products and potential products.

As is the case with other companies in our industry, our success depends in part on obtaining, maintaining, enforcing and defending intellectual property, particularly patents. Obtaining and enforcing patents in the life science industry involves technological and legal complexity, and obtaining and enforcing life science patents is costly, time-consuming and inherently uncertain. Changes in either the patent laws or their interpretation in the United States or other jurisdictions may increase the uncertainties and costs surrounding the prosecution of our patents, diminish our ability to protect our inventions, obtain, maintain, defend, and enforce our intellectual property rights and, more generally, affect the value of our intellectual property or narrow the scope of our patent rights.

The Leahy-Smith America Invents Act (the “AIA”), which was passed in September 2011, resulted in significant changes to the U.S. patent system. An important change introduced by the AIA is that, as of March 16, 2013, the United States transitioned from a “first-to-invent” to a “first-inventor-to-file” system for deciding which party should be granted a patent when two or more patent applications are filed by different parties claiming the same invention. Under a “first-inventor-to-file” system, assuming the other requirements for patentability are met, the first inventor to file a patent application generally will be entitled to a patent on the invention regardless of whether another inventor had made the invention earlier. A third party that files a patent application in the United States Patent and Trademark Office (the “USPTO”), after March 16, 2013 but before us could therefore be awarded a patent covering an invention similar or indentical to one of ours even if we made our invention before the third party made theirs. This will require us to be cognizant going forward of the time from invention to filing of a patent application and be diligent in filing patent applications, but circumstances could prevent us from promptly filing patent applications on our inventions.

44

Table of Contents

Among some of the other changes introduced by the AIA are changes that limit where a patentee may file a patent infringement suit and provide additional opportunities for third parties to challenge any issued patent in the USPTO. This applies to all of our U.S. patents, even those issued before March 16, 2013. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in U.S. federal district courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action. It is not clear what, if any, impact the AIA will have on the operation of our business. However, the AIA and its implementation could increase the uncertainties and costs surrounding the prosecution of our or our licensors’ patent applications and the enforcement or defense of our or our licensors’ issued patents.

In addition, the United States federal government retains certain rights in inventions produced with its financial assistance under the Bayh-Dole Act. The federal government retains a “nonexclusive, nontransferable, irrevocable, paid-up license” for its own benefit. The Bayh-Dole Act also provides federal agencies with “march-in rights.” March-in rights allow the government, in specified circumstances, to require the contractor or successors in title to the patent to grant a “nonexclusive, partially exclusive, or exclusive license” to a “responsible applicant or applicants.” If the patent owner refuses to do so, the government may grant the license itself. Some of our licensed patents are subject to the provisions of the Bayh-Dole Act. If our licensors fail to comply with the regulations of the Bayh-Dole Act, they could lose title to any patents subject to such regulations, which could affect our license rights under the patents and our ability to stop others from using or commercializing similar or identical technology and products, or limit patent protection for our technology and products.

The United States and many other countries have adopted a doctrine of “patent exhaustion,” which provides that once a patentee sells one of its products, it can no longer exercise control over the specific product. This could limit our ability to rely on our patents to prevent the import of products we have placed into the market in one jurisdiction into another jurisdiction.

Additionally, the U.S. Supreme Court has ruled on several patent cases in recent years either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations, and there are other open questions under patent law that courts have yet to decisively address. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways and could weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future. In addition, European patent laws can be complex and uncertain, and there could be similar changes in the laws of foreign jurisdictions that may impact the value of our patent rights or our other intellectual property rights. Complying with these laws and regulations could limit our ability to obtain new patents in the future that may be important for our business, and changes in such laws may have an adverse effect on our patent rights and our ability to protect, defend and enforce our patent rights in the future, as well as on our competitive position, business, financial condition, results of operations and prospects.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

The USPTO, European Patent Office (“EPO”) and other patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. In addition, periodic maintenance and annuity fees on any issued patent are due to be paid to the USPTO, EPO and other patent agencies over the lifetime of the patent. While an inadvertent failure to make timely payment of such

45

Table of Contents

fees or to comply with such provisions can in many cases within a reasonable timeframe be cured by additional payment of a late fee or by other means in accordance with the applicable rules, there are situations and time frames in which non-compliance with such provisions will result in the abandonment or lapse of the patent or patent application, and the partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or patent application include failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents within prescribed time limits. If we or our licensors fail to maintain the patents and patent applications covering our products and potential products or if we or our licensors otherwise allow our patents or patent applications to be abandoned or lapse, it can create opportunities for competitors to enter the market, which would hurt our competitive position and could impair our ability to successfully commercialize our products.

We enjoy only limited geographical protection with respect to certain patents, and we may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents covering our technology, products and potential products in all countries throughout the world would be prohibitively expensive, and even in countries where we have sought protection for our intellectual property, such protection can be less extensive than those in the United States. The requirements for patentability may differ in certain countries, particularly developing countries, and the breadth of patent claims allowed can be inconsistent. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. In-licensing patents covering our products and potential products in all countries throughout the world may similarly be prohibitively expensive, if such opportunities are available at all. And in-licensing or filing, prosecuting and defending patents even in only those jurisdictions in which we develop or commercialize our products and potential products may be prohibitively expensive or impractical. Competitors may use our and our licensors’ technologies in jurisdictions where we have not obtained patent protection or licensed patents to develop their own products and, further, may export otherwise infringing products to territories where we and our licensors have patent protection, but where enforcement is not as strong as that in the United States or the European Union. These products may compete with our products, and our or our licensors’ patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many jurisdictions have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many jurisdictions limit the enforceability of patents against government agencies or government contractors. In these jurisdictions, the patent owner may have limited remedies, which could materially diminish the value of such patents. If we or any of our licensors are forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be adversely impacted, which could have a material adverse effect on our business.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal system in certain foreign jurisdictions, particularly those in certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property protection which could make it difficult for us to stop the infringement, misappropriation or other violation of our patents or other intellectual property rights, or the marketing of competing products in violation of our proprietary rights in these jurisdictions. Proceedings to enforce our patent and other intellectual property rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents and other intellectual property rights at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a commercial advantage from the intellectual property that we develop or license. Any of the foregoing could have an adverse effect on our competitive position, business, financial condition, results of operations and prospects.

Table of Contents

Patent terms may be inadequate to protect our competitive position on our products and potential products for an adequate amount of time.

The term of any individual patent depends on applicable law in the country where the patent is granted. In the United States, provided all maintenance fees are timely paid, a patent generally has a term of 20 years from its application filing date or earliest claimed non-provisional filing date. Extensions and adjustments may be available under certain circumstances, but the life of a patent and, correspondingly, the protection it affords is limited. Even if we or our licensors obtain patents covering our products and potential products, when the terms of all patents covering a product or potential product expire, our business may become subject to competition with respect to that product. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours for an adequate amount of time.

We may not be able to rely on our patents to stop certain activities by third parties.

The United States and many other countries have provisions that exempt certain activities from patent infringement. For example, in the United States, “safe harbor” provisions shield infringement activities that are reasonably related to obtaining regulatory approval for certain medicinal products. This may limit our ability to stop others from using our technology, products and potential products. Third parties might use our patented technology, make and sell our patented products or otherwise perform an act that infringes one or more of our patents. We may not have sufficient financial or other resources to conduct appropriate litigation or other proceedings to stop such infringing acts. This could diminish the value of our patents.

We depend on proprietary technology licensed from others. If we lose our existing licenses or are unable to acquire or license additional proprietary rights from third parties, we may not be able to continue developing our potential products.

We are a party to certain license agreements for certain intellectual property and proprietary technology, and we may enter into additional agreements, including license agreements, with other parties in the future that impose diligence, development and commercialization timelines, milestone payments, royalties, insurance and other obligations on us. If we fail to comply with our obligations to our licensors or any of our other current or future collaborators, our counterparties may have the right to terminate these agreements, in which event we might not be able to develop, manufacture or market any product, potential product or other technology that is covered by these agreements, which could adversely affect the value of the potential product being developed under any such agreement, or we may face claims for monetary damages or other penalties under these agreements. Termination of these agreements or reduction or elimination of our rights under these agreements may result in us having to negotiate new or reinstated agreements with less favorable terms, or cause us to lose our rights under these agreements, including our rights to important intellectual property or technology. In addition, such an event may cause us to experience significant delays in the development and commercialization of our products, potential products or technologies or incur liability for damages. If any such license is terminated, our competitors or other third parties could have the freedom to seek regulatory approval of, and to market, products and technologies identical or competitive to ours, and we may be required to cease our development and commercialization of certain of our products, potential products or technologies.

We may rely on third parties from whom we license proprietary technology to file and prosecute patent applications and maintain patents and otherwise protect the intellectual property we license from them. We may have limited control over these activities or any other intellectual property that may be related to our in-licensed intellectual property. For example, we cannot be certain that such activities by these licensors will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents and other intellectual property rights. We may have limited control over the manner in which our licensors initiate an infringement proceeding against a third-party infringer of the intellectual property rights, or defend certain of the intellectual property that may be licensed to us. It is possible that the licensors’ infringement proceeding or defense activities may be less vigorous than if we conduct them ourselves.

The growth of our business may depend in part on our ability to acquire or in-license additional proprietary rights. We may be unable to acquire or in-license any relevant third-party intellectual property rights that we identify as necessary or important to our business operations. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all, which would harm our business. In that event, we may be required to expend significant time and resources to redesign our products, potential products or technologies or the methods for manufacturing them or to develop or license replacement technology, all of which may not be feasible on a technical or commercial basis. If we are unable to do so, we may be unable to develop or commercialize the affected products, potential products or technologies, which could adversely impact our business, financial condition, results of operations and prospects. Even if we are able to obtain a license under such intellectual property rights, any such license may be non-exclusive, which may allow our competitors access to the same technologies licensed to us.

Disputes may arise regarding intellectual property subject to a license agreement, including:

In addition, the agreements under which we license intellectual property or technology from third parties are, and any such future license agreements are likely to be, complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our diligence, financial or other obligations under the relevant agreement, or we may face claims for monetary damages or other penalties under these agreements, any of which could have an adverse effect on our business, financial condition, results of operations, and prospects. Moreover, if disputes over intellectual property that we have licensed or any other dispute described above related to our license agreements prevent or impair our ability to maintain our licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected products, potential products or technologies. Any of the foregoing could have an adverse effect on our competitive position, business, financial condition, results of operations and prospects.

We may become involved in lawsuits to protect or enforce our intellectual property, which could be expensive, time consuming and unsuccessful and have an adverse effect on the success of our business.

Competitors or other third parties may infringe, misappropriate or otherwise violate our patents or other intellectual property. If we or one of our licensors were to initiate legal proceedings against a third party to enforce a patent covering one of our products or potential products, the defendant could counterclaim that our patent is invalid or unenforceable. In patent litigation in the United States and in European countries, defendant counterclaims alleging invalidity or unenforceability are commonplace. Third parties may initiate invalidity proceedings even in the absence of infringement proceedings. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, for example, lack of novelty, obviousness, lack of

48

Table of Contents

written description, non-enablement or lack of entitlement. Third parties might allege unenforceability of our patents in the United States because during prosecution of the patent an individual connected with such prosecution withheld relevant information, or made a misleading statement. Interference or derivation proceedings provoked by third parties or brought by us or declared by the USPTO may be necessary to determine the priority of inventions with respect to our patents or patent applications. The outcome of proceedings involving assertions of invalidity and unenforceability during patent litigation is unpredictable.

If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on our products, potential products and other technology, which may allow third parties to commercialize our technology or products and compete directly with us, without payment to us, or could require us to obtain license rights from the prevailing party in order to be able to manufacture or commercialize our products, potential products or technologies without infringing third-party patent rights. Even if a defendant does not prevail on a legal assertion of invalidity or unenforceability, our patent claims may be construed in a manner that would limit our ability to enforce such claims against the defendant and others. Furthermore, many of our current and potential competitors may have, or may gain, the ability to dedicate substantially greater resources to enforce and defend their intellectual property rights than we can. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon, misappropriating or otherwise violating our intellectual property rights. Thus, even if we were to ultimately prevail, or to settle at an early stage, such litigation could burden us with substantial unanticipated costs. Our patents and other intellectual property rights also will not protect our technology, products and potential products if competitors design around our protected technology, products and potential products without infringing our patents or other intellectual property rights.

Third parties may assert claims against us alleging infringement, misappropriations or other violations of their patents and proprietary rights, or we may need to become involved in lawsuits to defend or enforce our patents, either of which could result in substantial costs or loss of productivity, delay or prevent the development and commercialization of our products and potential products, or prohibit our use of proprietary technology or sale of products.

Our commercial success depends, in part, upon our ability to develop, manufacture, market and sell our products and other technologies without alleged or actual infringement, misappropriation or other violation of the patents and proprietary rights of third parties. However, our research, development and commercialization activities may be subject to claims that we infringe, misappropriate or otherwise violate patents or other intellectual property rights owned or controlled by third parties. Litigation relating to infringement or misappropriation of patent and other intellectual property rights in the life science industry is common, including patent infringement lawsuits, interferences, derivation and administrative law proceedings, inter partes review and post-grant review before the USPTO, as well as oppositions and similar processes in foreign jurisdictions. The various markets in which we plan to operate can be subject to litigation regarding patents and other intellectual property rights. Our competitors in both the United States and abroad, many of which have substantially greater resources and have made substantial investments in patent portfolios and competing technologies, may have applied for or obtained or may in the future apply for or obtain, patents that will prevent, limit or otherwise interfere with our ability to make, use and sell our products. In addition, many companies in intellectual property-dependent industries, including the life science industry, have employed intellectual property litigation as a means to gain an advantage over their competitors. Some claimants may have substantially greater resources than we do and may be able to sustain the costs of complex intellectual property litigation to a greater degree and for longer periods of time than we could. In addition, patent holding companies that focus solely on extracting royalties and settlements by enforcing patent rights may target us.

We may be subject to third-party claims including infringement, interference or derivation proceedings, post-grant review and inter partes review before the USPTO or similar adversarial proceedings or litigation in other jurisdictions. Even if we believe such claims are without merit, a court of competent jurisdiction could hold that these third-party patents are valid, enforceable and infringed, and the holders of any such patents may be

49

Table of Contents

able to block our ability to commercialize the applicable product or potential product unless we obtained a license under the applicable patents, or until such patents expire or are finally determined to be invalid or unenforceable. Because patent applications can take many years to issue, there may be currently pending patent applications which may later result in issued patents that our products, potential products or technologies may infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies, products and potential products infringes upon these patents. If any third-party patents were held by a court of competent jurisdiction to cover aspects of our products, potential products or technologies, the holders of any such patents may be able to prohibit our commercialization of the applicable product, potential product or technology until such patent expires or is finally determined to be invalid or unenforceable or unless we obtained a license.

In addition, defending such claims would cause us to incur substantial expenses and, if successful, could cause us to pay substantial damages if we are found to be infringing a third party’s patent rights. These damages potentially include royalties, increased damages (possibly treble damages) and attorneys’ fees if we are found to have infringed such rights willfully. Further, if a patent infringement suit is brought against us, our development, manufacturing or sales activities relating to the product, potential product or technology that is the subject of the suit may be delayed or terminated, as parties making claims against us may obtain injunctive or other equitable relief. As a result of patent infringement claims, or in order to avoid potential infringement claims, we may choose to seek, or be required to seek, a license from the third party, which may require payment of substantial royalties or fees, or require us to grant a cross-license under our intellectual property rights. These licenses may not be available on reasonable terms or at all. Even if a license can be obtained on reasonable terms, the rights may be nonexclusive, which would give our competitors access to the same intellectual property rights. If we are unable to enter into a license on acceptable terms, we could be prevented from commercializing one or more of our products, potential products or technologies, or forced to modify such products or potential products, or to cease some aspect of our business operations, which could harm our business significantly. We might also be forced to redesign or modify our products, potential products or technologies so that we no longer infringe the third-party intellectual property rights, which may result in significant cost or delay to us, or which redesign or modification could be impossible or technically infeasible.

Even if we were ultimately to prevail, any of these events could require us to divert substantial financial and management resources that we would otherwise be able to devote to our business. Intellectual property litigation, regardless of its outcome, may cause negative publicity, adversely impact prospective customers, cause product shipment delays, or prohibit us from manufacturing, importing, marketing or otherwise commercializing our products, potential products, services and technology. In addition, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments, and if securities analysts or investors view these announcements in a negative light, the price of our common stock could be adversely affected. Such litigation or proceedings could substantially increase our operating losses and reduce our resources available for development activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have an adverse effect on our ability to compete in the marketplace.

Our trade secrets may be misappropriated or disclosed, and confidentiality agreements with employees and third parties may not adequately prevent disclosure of trade secrets and protect other proprietary information.

We consider proprietary trade secrets, confidential know-how and unpatented know-how to be important to our business. We may rely on trade secrets and confidential know-how to protect our technology, especially where patent protection is believed by us to be of limited value. However, trade secrets and confidential know-how are difficult to protect, and we have limited control over the protection of trade secrets and confidential know-how used by our licensors, collaborators and suppliers.

50

Table of Contents

To protect this type of information against disclosure or appropriation by competitors, our policy is to require our employees, consultants, contractors and advisors to enter into confidentiality agreements and, if applicable, material transfer agreements, consulting agreements or other similar agreements with us prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information, including our trade secrets. However, current or former employees, consultants, contractors and advisers may unintentionally or willfully disclose our confidential information to competitors, and confidentiality agreements may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. The need to share trade secrets and other confidential information increases the risk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements. Given that our competitive position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or other unauthorized use or disclosure would impair our competitive position and may have an adverse effect on our business and results of operations. Monitoring unauthorized uses and disclosures is difficult, and we do not know whether the steps we have taken to protect our proprietary technologies will be effective. Enforcing a claim that a third party obtained illegally and is using trade secrets and/or confidential know-how is expensive, time consuming and unpredictable, and the enforceability of confidentiality agreements may vary from jurisdiction to jurisdiction. Courts outside the United States are sometimes less willing to protect proprietary information, technology and know-how. Furthermore, if any of our trade secrets and confidential know-how were to be lawfully obtained or independently developed by a competitor or other third party, we would have no right to prevent them from using that technology or information to compete with us, and our competitive position would be harmed.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of their former employers or other third parties, and we may be subject to claims asserting ownership of what we regard as our own intellectual property.

We do and may employ individuals who were previously employed at universities or other life science companies, including our licensors, competitors or potential competitors. Although we seek to protect our ownership of intellectual property rights by ensuring that our agreements with our employees, consultants, collaborators, independent contractors and other third parties with whom we do business include provisions requiring such parties to assign rights in inventions to us and to not use the know-how or confidential information of their former employer or other third parties, we may be subject to claims that we or our employees, consultants, collaborators or independent contractors have inadvertently or otherwise used or disclosed know-how or confidential information of their former employers or other third parties. We may also be subject to claims that former employers or other third parties have an ownership interest in our patents. Litigation may be necessary to defend against these claims. There is no guarantee of success in defending these claims, and if we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable personnel or intellectual property rights, such as exclusive ownership of, or right to use, valuable intellectual property, which could result in customers seeking other sources for the technology, or in ceasing from doing business with us. Such intellectual property rights could be awarded to a third party, and we could be required to obtain a license from such third party to commercialize our technology or potential product. Such a license may not be available on commercially reasonable terms or at all. Even if we are successful, litigation could result in substantial cost and reputational loss and be a distraction to our management and other employees. Moreover, any such litigation or the threat thereof may adversely affect our reputation, our ability to form strategic alliances, engage with scientific advisors or hire employees or consultants, each of which would have an adverse effect on our business, financial condition and results of operations.

In addition, while we typically require our employees, consultants and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own. Furthermore, even when we obtain agreements assigning intellectual property to us, the assignment of intellectual property rights may not be self-executing, or

51

Table of Contents

the assignment agreements may be breached, each of which may result in claims by or against us related to the ownership of such intellectual property to determine the ownership of what we regard as our intellectual property. In addition, individuals executing agreements with us may have pre-existing or competing obligations to a third party, such as an academic institution, and thus an agreement with us may be ineffective in perfecting ownership of inventions developed by that individual. If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. Even if we are successful in prosecuting or defending any of the foregoing claims, litigation could result in substantial costs and be a distraction to our management and employees.

If our trademarks and trade names are not adequately protected, we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

If our trademarks and trade names are not adequately protected, we may not be able to build name recognition in our markets of interest and our business may be adversely affected. We currently own issued trademark registrations and have trademark applications pending, any of which may be the subject of a governmental or third-party objection, which could prevent the registration or maintenance of the same. We cannot assure you that any currently pending trademark applications or any trademark applications we may file in the future will be approved. During trademark registration proceedings, we may receive rejections and although we are given an opportunity to respond to those rejections, we may be unable to overcome such rejections. In addition, in proceedings before the USPTO and in proceedings before comparable agencies in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive such proceedings. If we are unsuccessful in obtaining trademark protection for our primary brand, we may be required to change our brand name, which could adversely affect our business.

We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition among potential partners or customers in our markets of interest. At times, competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our unregistered trademarks or trade names. Over the long term, if we are unable to successfully register our trademarks and trade names and establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively and our business may be adversely affected. Our efforts to enforce or protect our proprietary rights related to trademarks, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could result in substantial costs and diversion of resources and could adversely impact our financial condition or results of operations.

Intellectual property rights do not necessarily protect us from all potential threats.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may not adequately protect our business or permit us to maintain our competitive advantage. For example:

Should any of these events occur, they could have an adverse effect on our competitive position, business, financial condition or results of operations.

Risks Relating to Our ADSs and this Offering

The price of our ADSs may be volatile and may fluctuate due to factors beyond our control.

The initial public offering price for the ADSs was determined through negotiations between the underwriters and us, and may vary from the market price of ADSs following this offering. If you purchase ADSs in this offering, you may not be able to resell those ADSs at or above the initial public offering price. The market price of our ADSs may fluctuate significantly due to a variety of factors, including:

53

Table of Contents

These and other market and industry factors may cause the market price and demand for our ADSs to fluctuate substantially, regardless of our actual operating performance, which may limit or prevent investors from readily selling their ADSs and may otherwise negatively affect the liquidity of our ADSs. In addition, the stock market in general, and pharmaceutical, biotechnology and diagnostics companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. In the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the issuer. If any of the holders of our ADSs were to bring such a lawsuit against us, we could incur substantial costs defending the lawsuit and the attention of our senior management would be diverted from the operation of our business. Any adverse determination in litigation could also subject us to significant liabilities.

There has been no public market for our ADSs prior to this offering, and an active market may not develop in which investors can resell our ADSs.

Prior to this offering, there has been no public market for our ADSs, although our ordinary shares have traded on AIM. We cannot predict the extent to which an active market for our ADSs will develop or be sustained or how the development of such a market might affect the market price for our ADSs. The initial public offering price of our ADSs has been agreed upon between us and the underwriters based on a number of factors, including market conditions in effect at the time of the offering, which may not be indicative of the price at which our ADSs will trade following completion of the offering. Investors may not be able to sell their ADSs at or above the initial public offering price.

If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about our business, the price of our ADSs and our trading volume could decline.

The trading market for our ADSs will depend in part on the research and reports that securities or industry analysts publish about us or our business. Securities and industry analysts do not currently, and may never, publish research on us. If no or too few securities or industry analysts commence coverage on us, the trading price for our ADSs would likely be negatively affected. In the event securities or industry analysts initiate coverage, if one or more of the analysts who cover us downgrade our ADSs or publish inaccurate or unfavorable research about our business, the price of our ADSs would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our ADSs could decrease, which might cause the price of our ADSs and trading volume to decline.

We have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

Our management will have broad discretion in the application of the net proceeds from this offering and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our ADSs. The failure by our management to apply these funds effectively could result in financial losses or cause the price of our ADSs to decline. Pending their use, we may invest the net proceeds from this offering in a manner that does not produce income or that loses value.

The dual listing of our ordinary shares and our ADSs following this offering may adversely affect the liquidity and value of our ordinary shares and ADSs.

Following this offering and after our ADSs begin trading on Nasdaq, our ordinary shares will continue to be admitted to trading on AIM. We cannot predict the effect of this dual listing on the value of our ADSs and

54

Table of Contents

ordinary shares. However, the dual listing of our ADSs and ordinary shares may dilute the liquidity of these securities in one or both markets and may adversely affect the development of an active trading market for our ADSs in the United States. The price of our ADSs could also be adversely affected by trading in our ordinary shares on AIM. Although our ordinary shares are currently admitted to trading on AIM, we may decide to cancel the admission of our ordinary shares to trading on AIM. Cancellation of the admission of our ordinary shares to trading on AIM would require the requisite consent of shareholders in a general meeting prescribed by AIM Rules for Companies, unless the London Stock Exchange agrees otherwise. We cannot predict the effect such cancellation would have on the market price of our ADSs or ordinary shares.

We are an “emerging growth company,” and we cannot be certain if the reduced reporting requirements applicable to “emerging growth companies” will make our ADSs less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. As an emerging growth company, we are required to report only two years of financial results and selected financial data in our initial public offering registration statement, as compared to three and five years, respectively, for comparable data reported by other public companies. We may take advantage of these exemptions until we are no longer an emerging growth company. We could be an emerging growth company for up to five years, although circumstances could cause us to lose that status earlier, including if the aggregate market value of our ADSs and ordinary shares held by non-affiliates exceeds $700 million as of any December 31 (the end of our second fiscal quarter) before that time, in which case we would no longer be an emerging growth company as of the following June 30 (our fiscal year-end). We cannot predict if investors will find our ADSs less attractive because we may rely on these exemptions. If some investors find our ADSs less attractive as a result, there may be a less active trading market for our ADSs and the price of our ADSs may be more volatile.

We qualify as a foreign private issuer and, as a result, we will not be subject to U.S. proxy rules and will be subject to Exchange Act reporting obligations that, to some extent, are more lenient and less frequent than those of a U.S. domestic public company.

Upon the closing of this offering, we will report under the Exchange Act as a non-U.S. company with foreign private issuer status. Because we qualify as a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, including (i) the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act; (ii) the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time; and (iii) the rules under the Exchange Act requiring the filing with the SEC of quarterly reports on Form 10-Q containing unaudited financial and other specified information, or current reports on Form 8-K, upon the occurrence of specified significant events. In addition, foreign private issuers are not required to file their annual report on Form 20-F until 120 days after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their annual report on Form 10-K within 75 days after the end of each fiscal year. Foreign private issuers also are exempt from Regulation Fair Disclosure, aimed at preventing issuers from making selective disclosures of material information. As a result of the above, you may not have the same protections afforded to shareholders of companies that are not foreign private issuers, some investors may find the ADSs less attractive, and there may be a less active trading market for the ADSs.

As a foreign private issuer, we are permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from Nasdaq corporate governance listing standards. These practices may afford less protection to shareholders than they would enjoy if we complied fully with Nasdaq corporate governance listing standards.

As a foreign private issuer listed on Nasdaq, we will be subject to corporate governance listing standards. However, Nasdaq rules permit a foreign private issuer like us to follow the corporate governance practices of its home country in lieu of certain Nasdaq corporate governance listing standards, provided that we disclose which requirements that we have not complied with in any year and confirm the U.K. corporate governance practices we have complied with. Certain corporate governance practices in the United Kingdom, which is our home country, may differ significantly from Nasdaq corporate governance listing standards. For example, neither the laws of the United Kingdom nor our articles of association (“Articles of Association”) have quorum requirements similar to Nasdaq Rule 5602(c). Although we voluntarily comply with the higher corporate governance standards of the U.K. Corporate Governance Code, we could include non-independent directors as members of our nomination and remuneration committee, and our independent directors would not necessarily hold regularly scheduled meetings at which only independent directors are present. We may in the future elect to follow home country practices in the United Kingdom with regard to other matters. Therefore, our shareholders may be afforded less protection than they otherwise would have under Nasdaq corporate governance listing standards applicable to U.S. domestic issuers. See “Management—Corporate Governance Practices and Foreign Private Issuer Status.”

We may lose our foreign private issuer status, which would then require us to comply with the Exchange Act’s domestic reporting regime and cause us to incur significant legal, accounting and other expenses.

As a foreign private issuer, we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act applicable to U.S. domestic issuers. We may no longer be a foreign private issuer as of December 31, 2020 (the end of our second fiscal quarter in the fiscal year after this offering), which would require us to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act applicable to U.S. domestic issuers as of July 1, 2021. In order to maintain our current status as a foreign private issuer, either (a) a majority of our ADSs must be either directly or indirectly owned of record by non-residents of the United States or (b)(i) a majority of our executive officers or directors cannot be U.S. citizens or residents, (ii) more than 50 percent of our assets must be located outside the United States and (iii) our business must be administered principally outside the United States. If we lose our status as a foreign private issuer, we would be required to comply with the Exchange Act reporting and other requirements applicable to U.S. domestic issuers, including the requirement to prepare our financial statements in accordance with U.S. generally accepted accounting principles, which are more detailed and extensive than the requirements for foreign private issuers. We may also be required to make changes in our corporate governance practices in accordance with various SEC and Nasdaq rules. The regulatory and compliance costs to us under U.S. securities laws if we are required to comply with the reporting requirements applicable to a U.S. domestic issuer may be significantly higher than the cost we would incur as a foreign private issuer. As a result, we expect that a loss of foreign private issuer status would increase our legal and financial compliance costs and would make some activities highly time consuming and costly. If we lose foreign private issuer status and are unable to comply with the reporting requirements applicable to a U.S. domestic issuer by the applicable deadlines, we would not be in compliance with applicable SEC rules or the rules of the Nasdaq, which could cause investors could lose confidence in our public reports and could have a material adverse effect on the trading price of our ADSs. We also expect that if we were required to comply with the rules and regulations applicable to U.S. domestic issuers, it would make it more difficult and expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified members of our board of directors.

Failure to comply with requirements to design, implement and maintain effective internal control over financial reporting could have a material adverse effect on our business. We have identified a material weakness in our internal control over financial reporting.

As a U.K. public company traded on AIM, we were not required to evaluate our internal control over financial reporting in a manner that meets the standards of publicly traded companies required by Section 404(a) of the Sarbanes-Oxley Act.

As a public company in the United States, we must maintain effective internal control over financial reporting in order to report in an accurate and timely manner the results of our operations and financial condition. In addition, the Sarbanes-Oxley Act will require, among other things, that we assess the effectiveness of our internal control over financial reporting at the end of each fiscal year. The process of designing and implementing effective internal controls over financial reporting is a continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources to maintain a system of internal controls that is adequate to satisfy our reporting obligations as a public company. If we are unable to establish or maintain appropriate internal financial reporting controls and procedures, it could cause us to fail to meet our reporting obligations on a timely basis, result in material misstatements in our consolidated financial statements and harm our results of operations. In addition, we will be required, pursuant to Section 404(a), to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting in the second annual report following the completion of this offering. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting. The rules governing the standards that must be met for our management to assess our internal control over financial reporting are complex and require significant documentation, testing and possible remediation. Testing and maintaining internal controls may divert our management’s attention from other matters that are important to our business. In addition, it is currently anticipated that our independent registered public accounting firm will be required to issue an audit report on the effectiveness of our internal control over financial reporting in the fifth annual report following the completion of this offering or the fiscal year following the date upon which we are no longer an emerging growth company, whichever is the sooner.

In connection with the implementation of the necessary procedures and practices related to our internal control over financial reporting, we may identify deficiencies that we may not be able to remediate in time to meet the deadline imposed by the Sarbanes-Oxley Act for compliance with the requirements of Section 404(a). In addition, we may encounter problems or delays in completing the remediation of any deficiencies identified by our independent registered public accounting firm in connection with the issuance of their audit report.

For the fiscal year ended June 30, 2019, we identified a material weakness in our internal control over financial reporting relating to access to program and data controls within one of our key financial systems that we rely upon for certain figures within our consolidated financial statements. This material weakness remained in the fiscal year ended June 30, 2020. This system is a collection of internally built applications operated by different teams across the business. Access rights within these applications are managed via “Security Groups,” with a designated access owner in each team responsible for managing the users within these Security Groups. There are a number of Security Groups in relation to areas that impact the consolidated financial statements, but there is currently no overall formally documented policy prescribing how often the list of users within the Security Groups should be reviewed. As a result, for a number of the Security Groups, access change reviews were not performed sufficiently and regularly, and there was also no documented evidence that access change controls have been performed to ensure the appropriate individuals have the relevant access to this system.

The data from this system principally impacts two consolidated financial statement line items, namely inventory and Internally Developed Technology (“IDT”). Because the review controls that could act as compensating controls are not performed to the appropriate level of rigor and documented regularity, this has been assessed as a material weakness owing to the risk that unauthorized or inappropriate changes to underlying

57

Table of Contents

data in that system could be made, which are then relied upon and could then affect the two consolidated financial statement line items set out above. To date, we have not identified that this control weakness has led to any errors in our consolidated financial statements, however, there can be no assurance that we will not identify any such errors in the future. We are implementing measures designed to improve and remediate the deficiencies that are causing this material weakness through formal documentation of user access review. We expect the documentation for these measures to be in place and functioning soon, and we continue to invest in our IT systems and infrastructure to introduce further enhancements to our internal controls over financial reporting as relevant modules go live. There can be no assurance that such measures will be effective to remediate the material weakness.

Internal review of our internal controls over financial reporting or the subsequent testing of these by our independent registered public accounting firm may reveal other deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses that could result in a material misstatement of our consolidated financial statements or disclosures that may not be prevented or detected.

We may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404(a) or our independent registered public accounting firm may not issue an unqualified opinion. If either we are unable to conclude that we have effective internal control over financial reporting or our independent registered public accounting firm is unable to provide us with an unqualified opinion, investors could lose confidence in our reported financial information, which could have a material adverse effect on the trading price of our ADSs.

We will incur increased costs as a result of operating as a public company in the United States, and our management will be required to devote substantial time to new compliance initiatives and corporate governance practices.

As a U.S. public company, and particularly after we no longer qualify as an emerging growth company, we will incur significant legal, accounting and other expenses that we did not incur previously. The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of Nasdaq and other applicable securities rules and regulations impose various requirements on non-U.S. reporting public companies, including the establishment and maintenance of effective disclosure and financial controls and corporate governance practices. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more time consuming and costly. For example, we expect that these rules and regulations may increase the cost of our director and officer liability insurance.

However, these rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, we will be required to furnish a report by our senior management on our internal control over financial reporting. However, while we remain an emerging growth company, we will not be required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. To prepare for eventual compliance with Section 404, once we no longer qualify as an emerging growth company, we will be engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that we will not be able to conclude, within the

58

Table of Contents

prescribed timeframe or at all, that our internal control over financial reporting is effective as required by Section 404. If we identify one or more material weaknesses, it could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements.

Future sales, or the possibility of future sales, of a substantial number of our ADSs could adversely affect the price of our ADSs.

Future sales of a substantial number of our ADSs, or the perception that such sales will occur, could cause a decline in the market price of our ADSs. Based upon the number of shares outstanding as of September 30, 2020, after giving effect to this offering, we will have 225,171,370 ordinary shares outstanding. ADSs sold in this offering may be resold in the public market immediately without restriction, unless purchased by our affiliates. Upon completion of this offering, we will have 225,171,370 ordinary shares outstanding, approximately 18,478,237 of which will be subject to 90-day, or in the case of Mr. Milner, 45-day, lock-up agreements entered into by our directors and officers and certain of our shareholders described in “Ordinary Shares and ADSs Eligible for Future Sale” and “Underwriters.” The representatives of the underwriters may, in their sole discretion, release all or any portion of the equity securities subject to the lock-up agreements prior to the expiration of the lock-up agreements. If, after the end of such lock-up agreements, these shareholders sell substantial amounts of ADSs in the public market, or the market perceives that such sales may occur, the market price of our ADSs and our ability to raise capital through an issue of equity securities in the future could be adversely affected.

If you purchase ADSs in this offering, you will suffer immediate dilution of your investment.

We expect the initial public offering price of our ADSs in this offering to be substantially higher than the net tangible book value per ADS prior to this offering. Therefore, if you purchase ADSs in this offering, you will pay a price per ADS that substantially exceeds our net tangible book value per ADS after this offering. To the extent outstanding options are exercised for ordinary shares, you may experience further dilution. Based on the initial public offering price of $17.50 per ADS, you will experience immediate dilution of $16.01 per ADS, representing the difference between our net tangible book value per ADS and per ordinary share after giving effect to this offering. See “Dilution.”

If we issue shares in future financings, shareholders may experience dilution and, as a result, our ADS price may decline.

We may from time to time issue additional shares at a discount from the trading price of our shares. As a result, our shareholders would experience immediate dilution upon the issuance of any of our shares at such discount. In addition, as opportunities present themselves, we may enter into financing or similar arrangements in the future, including the issuance of debt or equity securities. If we issue shares or securities convertible into shares of our share capital, our shareholders would experience additional dilution and, as a result, our ADS price may decline.

Because we may not pay any cash dividends on our ADSs in the future, capital appreciation, if any, may be your sole source of gains and you may never receive a return on your investment.

Under current U.K. law, a company’s accumulated realized profits, so far as not previously utilized by distribution or capitalization, must exceed its accumulated realized losses so far as not previously written off in a reduction or reorganization of capital duly made (on a non-consolidated basis), before dividends can be paid. Therefore, we must have distributable profits before issuing a dividend. In the future, our board of directors may decide, in its discretion, whether dividends may be declared and paid. As a result, capital appreciation, if any, on our ADSs may be your sole source of gains, and you will suffer a loss on your investment if you are unable to sell your ADSs at or above the offering price. See “Dividend Policy.”

Securities traded on AIM may carry a higher risk than securities traded on other exchanges, which may impact the value of your investment.

Our ordinary shares are currently traded on AIM. Investment in equities traded on AIM is sometimes perceived to carry a higher risk than an investment in equities quoted on exchanges with more stringent listing requirements, such as the main market of the London Stock Exchange, New York Stock Exchange or Nasdaq. This is because AIM imposes less stringent corporate governance and ongoing reporting requirements than those other exchanges. In addition, AIM requires only half-yearly, rather than quarterly, financial reporting. You should be aware that the value of our ordinary shares may be influenced by many factors, some of which may be specific to us and some of which may affect AIM-quoted companies generally, including the depth and liquidity of the market, our performance, a large or small volume of trading in our ordinary shares, legislative changes and general economic, political or regulatory conditions, and that the prices may be volatile and subject to extensive fluctuations. Therefore, the market price of our ordinary shares, our ADSs, or of the ordinary shares underlying our ADSs, may not reflect the underlying value of our company.

You may not be able to exercise your right to vote the ordinary shares underlying your ADSs.

ADS holders may only exercise voting rights with respect to the ordinary shares underlying their respective ADSs in accordance with the provisions of the deposit agreement, which provides that a holder may vote the ordinary shares underlying any ADSs for any particular matter to be voted on by our shareholders either by withdrawing the ordinary shares underlying the ADSs or, to the extent permitted by applicable law and as permitted by the depositary, by requesting a temporary registration as shareholder and authorizing the depositary to act as proxy. However, you may not know about the meeting far enough in advance to withdraw those ordinary shares, and after such a withdrawal you would no longer hold ADSs, but rather you would directly hold the underlying ordinary shares. You also may not know about the meeting far enough in advance to request a temporary registration.

The depositary will try, as far as practical, to vote the ordinary shares underlying the ADSs as instructed by the ADS holders. In such an instance, if we ask for your instructions, the depositary, upon timely notice from us, will notify you of the upcoming vote and arrange to deliver our voting materials to you. We cannot guarantee that you will receive the voting materials in time to ensure that you can instruct the depositary to vote your ordinary shares or to withdraw your ordinary shares so that you can vote them yourself. If the depositary does not receive timely voting instructions from you, it may give a discretionary proxy to a person designated by us to vote the ordinary shares underlying your ADSs; provided, however, that no such discretionary proxy shall be given with respect to any matter to be voted upon as to which we inform the depositary that (i) we do not wish such proxy to be given, (ii) substantial opposition exists, or (iii) the rights of holders of ordinary shares may be adversely affected. Voting instructions may be given only in respect of a number of ADSs representing an integral number of ordinary shares or other deposited securities. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that you may not be able to exercise any right to vote that you may have with respect to the underlying ordinary shares, and there may be nothing you can do if the ordinary shares underlying your ADSs are not voted as you requested. In addition, the depositary is only required to notify you of any particular vote if it receives notice from us in advance of the scheduled meeting.

You will not be directly holding our ordinary shares. Holders of the ADSs will not be able to exercise the preemptive subscription rights related to the ordinary shares that they represent and may suffer dilution of their equity holding in the event of future issuances of our ordinary shares.

English law generally provides shareholders with preemptive rights when new shares are issued for cash. Shareholders’ preemptive subscription rights, in the event of issuances of ordinary shares against cash payment, may be disapplied by a special resolution of the shareholders at a general meeting of our shareholders. On November 13, 2019, our shareholders approved the exclusion of preemptive rights, with such authority expiring

60

Table of Contents

at the conclusion of our next annual general meeting or, if earlier, the date 15 months after the date of approval. Such exclusion will need to be renewed upon expiration (i.e., on the conclusion of our next annual general meeting or, if earlier, the date 15 months after November 13, 2019) to remain effective, but may be sought more frequently for additional five-year terms (or any shorter period). The absence of preemptive rights for existing equity holders may cause dilution to such holders.

Furthermore, the ADS holders would not be entitled, even if such rights accrued to our shareholders in any given instance, to receive such preemptive subscription rights related to the ordinary shares that they represent. Rather, the depositary is required to endeavor to sell any such subscription rights that may accrue to the ordinary shares underlying the ADSs and to remit the net proceeds therefrom to the ADS holders pro rata. In addition, if the depositary is unable to sell rights, the depositary will allow the rights to lapse, in which case you will receive no value for these rights. Further, if we offer holders of our ordinary shares the option to receive dividends in either cash or ordinary shares, under the deposit agreement, ADS holders will not be permitted to elect to receive dividends in ordinary shares or cash, but will receive whichever option we provide as a default to shareholders who fail to make such an election.

Purchasers of ADSs in this offering may not receive distributions on our ordinary shares in the form of ADSs or any value for them if it is illegal or impractical to make them available to holders of ADSs.

The depositary for our ADSs has agreed to pay to purchasers of ADSs in this offering the cash dividends or other distributions it or the custodian receives on our ordinary shares or other deposited securities after deducting its fees and expenses. Purchasers of our ADSs will receive these distributions in proportion to the number of our ordinary shares their ADSs represent. However, in accordance with the limitations set forth in the deposit agreement, it may be unlawful or impractical to make a distribution available to holders of ADSs. We have no obligation to take any other action to permit the distribution of our ADSs, ordinary shares, rights or anything else to holders of our ADSs. This means that purchasers of ADSs in this offering may not receive the distributions we make on our ordinary shares or any value from them if it is unlawful or impractical to make them available to them. These restrictions may have a material adverse effect on the value of a purchaser’s ADSs.

Purchasers of ADSs in this offering may be subject to limitations on transfer of their ADSs.

ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to time when it deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason in accordance with the terms of the deposit agreement.

ADS holders may not be entitled to a jury trial with respect to claims arising under the deposit agreement, which could result in less favorable outcomes to the plaintiff(s) in any such action.

The deposit agreement governing the ADSs representing our ordinary shares provides that, to the fullest extent permitted by applicable law, holders and beneficial owners of ADSs irrevocably waive the right to a jury trial of any claim that they may have against us or the depositary arising from or relating to our ordinary shares, our ADSs or the deposit agreement, including any claim under the U.S. federal securities laws. The waiver continues to apply to claims that arise during the period when a holder holds the ADSs, even if the ADS holder subsequently withdraws the underlying ordinary shares.

However, you will not be deemed, by agreeing to the terms of the deposit agreement, to have waived our or the depositary’s compliance with U.S. federal securities laws and the rules and regulations promulgated thereunder. In fact, you cannot waive our or the depositary’s compliance with U.S. federal securities laws and the rules and regulations promulgated thereunder. If we or the depositary opposed a demand for jury trial relying on

61

Table of Contents

above-mentioned jury trial waiver, it is up to the court to determine whether such waiver was enforceable considering the facts and circumstances of that case in accordance with the applicable state and federal law.

If this jury trial waiver provision is prohibited by applicable law, an action could nevertheless proceed under the terms of the deposit agreement with a jury trial. To our knowledge, the enforceability of a jury trial waiver under the federal securities laws has not been finally adjudicated by a federal court or by the United States Supreme Court. Nonetheless, we believe that a jury trial waiver provision is generally enforceable under the laws of the State of New York, which govern the deposit agreement, by a federal or state court in the City of New York. In determining whether to enforce a jury trial waiver provision, New York courts will consider whether the visibility of the jury trial waiver provision within the agreement is sufficiently prominent such that a party has knowingly waived any right to trial by jury. We believe that this is the case with respect to the deposit agreement and the ADSs. In addition, New York courts will not enforce a jury trial waiver provision in order to bar a viable setoff or counterclaim sounding in fraud or one which is based upon a creditor’s negligence in failing to liquidate collateral upon a guarantor’s demand, or in the case of an intentional tort claim, none of which we believe are applicable in the case of the deposit agreement or the ADSs. If you or any other holders or beneficial owners of ADSs bring a claim against us or the depositary relating to the matters arising under the deposit agreement or our ADSs, including claims under federal securities laws, you or such other holder or beneficial owner may not have the right to a jury trial regarding such claims, which may limit and discourage lawsuits against us or the depositary. If a lawsuit is brought against us or the depositary according to the deposit agreement, it may be heard only by a judge or justice of the applicable trial court, which would be conducted according to different civil procedures and may have different outcomes compared to that of a jury trial, including results that could be less favorable to the plaintiff(s) in any such action.

Moreover, as the jury trial waiver relates to claims arising out of or relating to the ADSs or the deposit agreement, we believe that, as a matter of construction of the clause, the waiver would likely continue to apply to ADS holders who withdraw the ordinary shares from the ADS facility with respect to claims arising before the cancellation of the ADSs and the withdrawal of the ordinary shares, and the waiver would most likely not apply to ADS holders who subsequently withdraw the ordinary shares represented by ADSs from the ADS facility with respect to claims arising after the withdrawal. However, to our knowledge, there has been no case law on the applicability of the jury trial waiver to ADS holders who withdraw the ordinary shares represented by the ADSs from the ADS facility.

ADS holders have limited choice of forum, which could limit your ability to obtain a favorable judicial forum for complaints against us, the depositary or our respective directors, officers or employees.

The deposit agreement governing our ADSs provides that, (i) the deposit agreement and the ADSs will be interpreted in accordance with the laws of the State of New York, and (ii) as an owner of ADSs, you irrevocably agree that any legal action arising out of the deposit agreement and the ADSs involving us or the depositary may only be instituted in a state or federal court in the city of New York. Any person or entity purchasing or otherwise acquiring any our ADSs, whether by transfer, sale, operation of law or otherwise, shall be deemed to have notice of and have irrevocably agreed and consented to these provisions. This choice of forum provision may increase your cost and limit your ability to bring a claim in a judicial forum that you find favorable for disputes with us, the depositary or our and the depositary’s respective directors, officers or employees, which may discourage such lawsuits against us, the depositary and our and the depositary’s respective directors, officers or employees. However, it is possible that a court could find such choice of forum provisions to be inapplicable or unenforceable. The enforceability of similar choice of forum provisions has been challenged in legal proceedings. It is possible that a court could find this type of provisions to be inapplicable or unenforceable.

To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created

62

Table of Contents

by the Securities Act or the rules and regulations thereunder. Accordingly, actions by our ADS holders to enforce any duty or liability created by the Exchange Act, the Securities Act or the respective rules and regulations thereunder must be brought in a federal court in the city of New York. Our ADS holders will not be deemed to have waived our compliance with the federal securities laws and the regulations promulgated thereunder.

The rights of our shareholders may differ from the rights typically offered to shareholders of a U.S. corporation.

We are incorporated under English law. The rights of holders of ordinary shares and, therefore, certain of the rights of holders of ADSs, are governed by English law, including the provisions of the U.K. Companies Act 2006 (the “Companies Act 2006”), and by our Articles of Association. These rights differ in certain respects from the rights of shareholders in typical U.S. corporations. See “Description of Share Capital and Articles of Association—Differences in Corporate Law” in this prospectus for a description of the principal differences between the provisions of the Companies Act 2006 applicable to us and, for example, the Delaware General Corporation Law relating to shareholders’ rights and protections.

Claims of U.S. civil liabilities may not be enforceable against us.

We are incorporated under English law. Substantially all of our assets are located outside the United States. The majority of our management and board of directors reside outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon such persons or to enforce judgments obtained in U.S. courts against them or us, including judgments predicated upon the civil liability provisions of the U.S. federal securities laws.

The United States and the United Kingdom do not currently have a treaty providing for recognition and enforcement of judgments (other than arbitration awards) in civil and commercial matters. Consequently, a final judgment for payment given by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not automatically be recognized or enforceable in the United Kingdom. In addition, uncertainty exists as to whether U.K. courts would entertain original actions brought in the United Kingdom against us or our directors or senior management predicated upon the securities laws of the United States or any state in the United States. Any final and conclusive monetary judgment for a definite sum obtained against us in U.S. courts would be treated by the courts of the United Kingdom as a cause of action in itself and sued upon as a debt at common law so that no retrial of the issues would be necessary, provided that certain requirements are met. Whether these requirements are met in respect of a judgment based upon the civil liability provisions of the U.S. securities laws, including whether the award of monetary damages under such laws would constitute a penalty, is an issue for the court making such decision. If an English court gives judgment for the sum payable under a U.S. judgment, the English judgment will be enforceable by methods generally available for this purpose. These methods generally permit the English court discretion to prescribe the manner of enforcement.

As a result, U.S. investors may not be able to enforce against us or our executive officers, board of directors or certain experts named herein who are residents of the United Kingdom or countries other than the United States any judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities laws.

If we are classified as a passive foreign investment company for U.S. federal income tax purposes, U.S. Holders may incur adverse tax consequences.

Based on the nature and composition of our income, assets and operations and the income, assets and operations of our subsidiaries, we do not believe that we are currently a passive foreign investment company for U.S. federal income tax purposes (a “PFIC”), and we do not expect to be a PFIC in the foreseeable future. However, this is a factual determination that depends on, among other things, the nature and composition of our income and assets, and the market value of our shares and assets, including the nature and composition of income

63

Table of Contents

and assets and the market value of shares and assets of our subsidiaries, from time to time, and thus the determination can only be made annually after the close of each taxable year. Therefore, no assurance can be given that we will not be classified as a PFIC for the current taxable year or any future taxable year.

If we are considered a PFIC at any time that a U.S. Holder (as defined below under “Material Tax Considerations—Material United States Federal Income Tax Considerations”) holds the ordinary shares or ADSs, U.S. Holders may suffer material adverse tax consequences, including with respect to any “excess distribution” received from us and any gain from a sale or other taxable disposition of the ordinary shares or ADSs. U.S. Holders should consult their tax advisors about the potential application of the PFIC rules to an investment in the ordinary shares or ADSs and the potential consequences related thereto. See “Material Tax Considerations—Material United States Federal Income Tax Considerations—Passive Foreign Investment Company Considerations.”

If a United States person is treated as owning at least 10% of the ordinary shares or ADSs, such holder may be subject to adverse U.S. federal income tax consequences.

If a United States person (as defined in the Internal Revenue Code of 1986, as amended) is treated as owning (directly, indirectly, or constructively) at least 10% of the value or voting power of the ordinary shares or ADSs, such person may be treated as a “United States shareholder” with respect to each “controlled foreign corporation” (a “CFC”) in our group (if any). Under current law, if our group includes one or more U.S. subsidiaries, certain of our non-U.S. subsidiaries could be treated as CFCs regardless of whether or not we are treated as a CFC (although there is currently a pending legislative proposal to significantly limit the application of these rules). A United States shareholder of a CFC may be required to report annually and include in its U.S. taxable income its pro rata share of “Subpart F income,” “global intangible low-taxed income” and investments in U.S. property by CFCs, regardless of whether the Company makes any distributions. An individual that is a United States shareholder with respect to a CFC generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a United States shareholder that is a U.S. corporation. Failure to comply with these reporting obligations may subject a United States shareholder to significant monetary penalties and may prevent the statute of limitations with respect to such United States shareholder’s U.S. federal income tax return for the year for which reporting was due from starting. We cannot provide any assurances that we will assist holders of the ordinary shares or ADSs in determining whether we or any of our non-U.S. subsidiaries are treated as a CFC or whether any holder of the ordinary shares or ADSs is treated as a United States shareholder with respect to any such CFC or furnish to any United States shareholders information that may be necessary to comply with the aforementioned reporting and tax paying obligations. The United States Internal Revenue Service has provided limited guidance on situations in which investors may rely on publicly available information to comply with their reporting and taxpaying obligations with respect to foreign-controlled CFCs. A U.S. Holder should consult its advisors regarding the potential application of these rules to an investment in the ordinary shares or ADSs.

USE OF PROCEEDS

We estimate that the net proceeds to us from this offering will be approximately $142.8 million (or approximately $164.7 million if the underwriters exercise their option to purchase additional ADSs from us in full), after deducting the underwriting commission and estimated offering expenses payable by us, based on an initial public offering price of $17.50 per ADS.

The principal purposes of this offering are to create a public market for our ADSs, facilitate greater access to the public equity markets, increase our visibility in the marketplace, as well as to obtain additional capital. We intend to use the net proceeds from this offering for working capital, general corporate purposes and to fund incremental growth, including for possible acquisitions. However, we do not currently have any definitive or preliminary plans with respect to the use of proceeds for such purposes.

The amount of what, and timing of when, we actually spend for these purposes may vary significantly and will depend on a number of factors, including our future revenue and cash generated by operations and the other factors described in “Risk Factors.” Accordingly, we will have broad discretion in deploying the net proceeds of this offering.

DIVIDEND POLICY

In the future, our board of directors may decide, in its discretion, whether dividends may be proposed (in respect of final dividends) or declared and paid (in respect of interim dividends). Under English law, among other things, we may only pay dividends if we have sufficient distributable reserves (on a non-consolidated basis), which are our accumulated realized profits that have not been previously distributed or capitalized less our accumulated realized losses, so far as such losses have not been previously written off in a reduction or reorganization of capital.

In the years ended June 30, 2019 and 2020, we declared and paid dividends of an aggregate of £24.9 million and £25.0 million, respectively.

CAPITALIZATION

The following table sets forth our cash and cash equivalents and total capitalization as of June 30, 2020, as follows:

You should read this information in conjunction with our consolidated financial statements and the related notes appearing at the end of this prospectus and “Use of Proceeds,” “Selected Consolidated Financial and Other Data” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other financial information contained in this prospectus. For the convenience of the reader, we have translated pound sterling amounts in the table below as of June 30, 2020 into U.S. dollars at the noon buying rate of the Federal Reserve Bank of New York on June 30, 2020, which was £1.00 to $1.2369. These translations should not be considered representations that any such amounts have been, could have been or could be converted into U.S. dollars at that or any other exchange rate as of that or any other date.

As of June 30, 2020, we had 216,173,277 ordinary shares outstanding.

As adjusted equity amounts shown in the table above exclude the impact of:

DILUTION

If you invest in our ADSs, your interest will be diluted to the extent of the difference between the initial public offering price per ADS and the as adjusted net tangible book value per share immediately following the consummation of this offering. Unless otherwise stated, we translated pound sterling amounts into U.S. dollars in dilution calculations based on the noon buying rate of the Federal Reserve Bank of New York on June 30, 2020, which was £1.00 to $1.2369.

At June 30, 2020, we had a historical net tangible book value of $192.2 million, corresponding to a net tangible book value of $0.89 per share or $0.89 per ADS based on an ordinary share to ADS ratio of one to one. Net tangible book value per share represents the amount of our total assets less our total liabilities, excluding goodwill and other intangible assets, divided by the total number of our ordinary shares outstanding.

After giving effect to the sale by us of 8,945,218 ADSs (representing an aggregate of 8,945,218 ordinary shares) in this offering at the initial public offering price of $17.50 per ADS, after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value at June 30, 2020 would have been approximately $335.0 million, representing $1.49 per share or $1.49 per ADS. This represents an immediate increase in net tangible book value of $0.60 per share or $0.60 per ADS to existing shareholders and an immediate dilution in net tangible book value of $16.01 per share or $16.01 per ADS to new investors purchasing ADSs in this offering at the initial public offering price. Dilution in net tangible book value per ADS to new investors is determined by subtracting as adjusted net tangible book value per ADS after this offering from the initial public offering price per ADS paid by new investors.

The following table illustrates this dilution to new investors purchasing ADSs in the offering.

If the underwriters exercise their option to purchase additional ADSs from us in full, our as adjusted net tangible book value per ADS after this offering would be $1.58 per ADS, representing an immediate increase in as adjusted net tangible book value per ADS of $0.69 per ADS to existing shareholders and immediate dilution of $15.92 per ADS in as adjusted net tangible book value per ADS to new investors purchasing ADSs in this offering, based on an initial public offering price of $17.50 per ADS.

Overview

We are a global life science company focused on identifying, developing and distributing high-quality reagents and tools for our customers at the forefront of life science research. Our products are used by researchers to study biological pathways, which is critical for scientific research, diagnostics and drug discovery. 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 scientists and researchers in academic institutions, research institutes and pharmaceutical, biotechnology and diagnostics companies. Headquartered in Cambridge, United Kingdom, we operate across 15 locations around the world, supported by our world-class team of approximately 1,500 employees, including over 200 with PhDs, and have served customers in over 130 countries.

We offer a large and differentiated portfolio of approximately 100,000 products with over 300,000 SKUs as of June 30, 2020. 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 OEM 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 by making them available through our global distribution platform and customer service. Over the last five years, we have increased focus on the development of in-house products for research areas we expect to have high demand. This focus has seen our proprietary product portfolio grow to represent 51% of our total revenue for the fiscal year ended June 30, 2020, compared to 28% of our total revenue in the fiscal year ended June 30, 2012.

We are continuously expanding our portfolio to provide our customers with additional solutions and further expand within our addressable markets. Utilizing the foundations laid by our innovation platform and strategic acquisitions, our strategy is to leverage our capabilities to continue expansion into adjacencies and more comprehensive product offerings, including primary conjugated antibodies, singleplex and multiplex immunoassays, proteins and edited cell lines. In addition, through partnerships with biopharmaceutical and diagnostic companies, the potential application of our products is being extended into diagnostic and therapeutic markets.

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. In the fiscal year ended June 30, 2020, our worldwide customer base consisted of approximately 750,000 life science researchers. As of June 30, 2020, 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.

We recorded revenue of £260.0 million, profit for the year of £12.5 million and Adjusted Operating Profit of £44.5 million for the fiscal year ended June 30, 2020. Revenue was broadly flat for the fiscal year ended

June 30, 2020, as compared to the same period in the prior year. For the definition of Adjusted Operating Profit and reconciliation of Adjusted Operating Profit to profit for the year, please see “Prospectus Summary—Summary Consolidated Financial and Other Data—Non-IFRS Financial Measures.”

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.

Factors Affecting Our Performance

Our financial condition and results of operations have been, and will continue to be, affected by a number of important factors, including the following:

Strategic Acquisitions

We have made, and intend to continue to make, strategic acquisitions in our existing and adjacent customer markets to supplement our organic growth, solidify our current market presence and expand into new markets. We acquired the proteomics and immunology businesses of Expedeon AG (the “Expedeon Acquisition”) in January 2020 for £104.2 million, and we also made other acquisitions for a total consideration of £14.3 million in the fiscal years ended June 30, 2019 and 2020, comprising:

Our strategic acquisitions may affect our business growth and the comparability of our financial results. With the exception of the Expedeon Acquisition, the effects that these acquisitions had on our overall revenue and profitability in the fiscal years that they were acquired were relatively small. The Expedeon Acquisition contributed £5.9 million to revenue and £0.3 million to profit before tax for the period from acquisition to June 30, 2020. If the Expedeon Acquisition had been completed at the beginning of the fiscal year ended June 30, 2020, our revenue and profit before tax would have increased by £10.7 million and decreased by £0.3 million, respectively.

We intend to continue to selectively pursue strategic acquisitions to further strengthen our competitiveness. We will evaluate and execute opportunities that complement and scale our business, optimize our profitability, help us expand into adjacent markets and add new capabilities to our business.

Product Mix, Growth and Innovation

We offer a variety of products, and the products in our portfolio are sold at different prices and in different volumes. In any particular period, changes in the volume of particular products sold across our various markets and the prices of those products relative to other products will impact our cost of sales, our gross profit and our gross margin. We continue to increase our focus on our innovation platform to extend and improve our in-house proprietary product offering, which we believe will continue to expand our market share in research use markets and enable us to extend our product offering. Sales of in-house products generate a substantially higher gross margin than OEM product sales, and we also believe that in-house products will support continued market share expansion in research use markets while also enabling us to extend our product offering, through industry partners, to clinical applications. We expect to continue to devote significant resources to developing innovative new products, both as part of our existing portfolio and in complementary and adjacent markets. The acceptance and growth of such new products may vary. The volume of our products sold during a given period in any particular market will depend in part on our successfully introducing new products that generate additional demand as well as the extent to which new products may impact our sales of existing products.

Seasonality

We experience modest seasonal customer demand, generally as a result of vacation and academic schedules of our worldwide customer base. We typically see minor slowdowns around the summer and winter holidays and a slight increase during the academic year. We believe that this is caused by factors unique to those particular product markets such as customer manufacturing schedules, inventory levels in the supply chain and government approval processes. As a result, we may see fluctuations across periods as the timing of our customers’ demand for certain products may change.

Currency Exchange Rates

We have substantial global operations whose financial condition and results of operations have been and will continue to be impacted by changes in the exchange rate of the pound sterling into other currencies. See “—Quantitative and Qualitative Disclosure about Market Risk—Currency Risk” below.

Impact of COVID-19 Pandemic

The COVID-19 pandemic has adversely affected, and is expected to continue to adversely affect, elements of our business (including elements of our operations, supply chains and distribution systems). We are continuing to monitor closely how the pandemic and related response measures are affecting our business. Our production and manufacturing facilities are located around the world, so while certain facilities were shut down or operating at reduced capacity, our other locations were able to continue operating as normal. The pandemic reduced demand during the second half of the fiscal year ended June 30, 2020 as research laboratories globally were temporarily shut down or operating at reduced capacity, resulting in a decline in revenue in the second half of the fiscal year of approximately 10% compared with the second half of the fiscal year ended June 30, 2019. Our monthly revenue compared to the same period in the prior year decreased by 37.6% in April, 26.2% in May and 0.2% in June 2020. Although we have seen a reduction in demand due to the ongoing COVID-19 pandemic, we have not observed any significant changes in our underlying customer base, and we have been and will continue to serve our customers even at a reduced level until their activities return to normal. In April 2020, we began to see the reopening of laboratories in certain countries in Europe, and we have continued to see a gradual increase in activity across all regions since then. The gradual recovery of revenue we have seen compared with previous levels reflects the underlying factors affecting demand, including the easing of lockdown restrictions and the partial or full reopening of academic and biopharmaceutical research laboratories around the world.

We have not furloughed any of our staff and have not elected to participate in any of the other COVID-19 related government assistance schemes that have been implemented globally. On March 17, 2020, we drew £25 million on our revolving credit facility to provide sufficient flexibility through the COVID-19 pandemic. We have not sought or obtained any other funding as a result of the COVID-19 pandemic.

While we see demand and revenue returning, there remains significant uncertainty and geographical variation with regards to our outlook, particularly in North America where the number of COVID-19 cases is rising in several states with large research lab demand. We expect that our fiscal year 2021 results will be impacted by the COVID-19 pandemic; however, it is not possible to predict the ultimate impact of the developments described above or the full duration and impact of the pandemic.

Operating Expenses

Our operating expenses increased from the fiscal year 2019 to the fiscal year ended June 30, 2020. Consistent with our previously announced growth strategy, we intend to continue to increase our rate of investment in growth projects and expect our operating expenses will continue to increase in the fiscal year ended June 30, 2021 and the medium term as a result. In particular, we expect such increases in operating expenses relative to prior periods as we (i) continue to increase our investment in research and development, digital marketing and e-commerce, (ii)

76

Table of Contents

continue to expand into adjacent markets and build scalability into our operational infrastructure, including through further investment in our IT systems, infrastructure and business processes, and (iii) continue to invest in our people and increase our headcount. For the fiscal year ended June 30, 2020, our operating profit margin was 4.0% and our adjusted operating profit margin was 17.1%, and we expect our operating profit margins to continue to be lower as a result of the effects of COVID-19 and our investment plans in the short to medium-term.

Key Indicators of Performance and Financial Condition

The key indicators of performance and financial condition we monitor are set forth below. The following table sets forth our key financial and operating performance indicators for the fiscal years ended June 30, 2019 and 2020.

Components of Our Results of Operations

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, and which represents the significant majority of our revenue, 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 be in excess of the 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 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 us.

Cost of sales. Cost of sales primarily consists of:

78

Table of Contents

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.

Selling, general and administrative. Selling, general and administrative expenses primarily consist of salaries and related benefits, including share-based compensation for all functions other than research and development. 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 AIM. We expect that our general and administrative costs will increase in the future as our business expands and we increase our headcount to support the expected growth in our operating activities. These increases will likely include increased costs related to the hiring of additional personnel and fees to outside consultants, lawyers and accountants, among other expenses. Additionally, we anticipate increased costs associated with being a U.S. public company, including expenses related to services associated with maintaining compliance with stock exchange rules and SEC requirements, director compensation, insurance and investor relations costs.

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, including share-based compensation for research and development staff, costs of related facilities, materials and equipment, costs associated with obtaining and maintaining patents and other intellectual property, depreciation of research and development 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 these 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 RDEC, which provides relief against U.K. corporation tax. Broadly, RDECs provide a tax credit currently equal to 13% of “qualifying research and development expenditure” made from April 1, 2020 (the rate was previously 12% of qualifying research and development expenditure made from January 1, 2018 to March 31, 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 U.K. corporation tax, then certain rules apply that allow the RDEC to reduce the tax liability of

79

Table of Contents

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.

Exceptional items and amortization of acquisition intangibles. Exceptional items and amortization of acquisition intangibles is comprised of certain cash and non-cash items that we believe are not reflective of the normal course of our business and where the separate disclosure of such items enables a reader to isolate and evaluate the impact of such items on results and allows for a fuller understanding of underlying performance of the business. We identify and determine items to be exceptional based on their nature and incidence or by their significance. As a result, the composition of exceptional items may vary from year to year. Current components consist of impairment of intangible assets, systems and process improvement costs associated with our strategic ERP implementation which commenced in 2016, acquisition costs and integration and reorganization costs. Amortization of acquisition intangibles relates to the amortization of intangible assets brought onto the balance sheet at a fair value in accordance with IFRS 3 and arising specifically from acquisition activity.

Finance income. Finance income is comprised of interest received or receivable on cash deposits.

Finance costs. Finance costs consist mainly of the amortization of upfront fees incurred in setting up our revolving credit facility and other related facility fees, such as those for non-utilization. Finance costs additionally include interest expense on our revolving credit facility that was drawn down during the fiscal year ended June 30, 2020 and is treated as short term debt. 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 for us on July 1, 2019.

Tax. Our tax credit or expense consists of income taxes, with U.K. income being taxed at the U.K. 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 U.K. “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 effective rate of 10%, rather than the usual U.K. statutory rate of 19%.

Segment Reporting

We present our results of operations in the same way that we manage our business, evaluate our performance and allocate our resources. We have concluded that we have only one core business activity, and there are no separately identifiable business segments that provide individual products or services or a group of related products and services that would be subject to separate risks and returns. The financial information reported to our Chief Executive Officer, who is considered our chief operating decision maker, for the purposes of resource allocation and assessment of performance is based wholly on our overall activities. Therefore, we have determined that we only have one reportable segment, which is the sale of antibodies and related products.
