Market, Industry and Other Data

Throughout this prospectus, we refer to our market position or market share in various markets or regions. These references represent our best estimates of our market share at the time of this prospectus and are based on management’s knowledge of the industry and the market data and other statistical information obtained from independent industry publications, reports by market research firms or other published independent sources. We confirm that such information has been accurately reproduced and that, so far as we are aware, and are able to ascertain from information published by

iii

publicly available sources and other publications, no facts have been omitted which would render the reproduced information inaccurate or misleading. Industry publications, reports and other published data generally state that the information contained therein has been obtained from sources believed to be reliable. Certain other market and industry data included in this prospectus, including the size of certain markets, are based on estimates of our management. These estimates have been derived from our management’s knowledge and experience in the markets in which we operate, as well as information obtained from surveys, reports by market research firms, our customers, distributors, suppliers, trade and business organizations and other contacts in the markets in which we operate.

Unless specifically noted otherwise, information presented in this prospectus with respect to our position relative to other industry participants is based on information or sources for the year ended December 31, 2020. Market size and market growth information presented in this prospectus reflects estimates of market sizes and growth in such markets for the year ended December 31, 2020 and for the years ended December 31, 2020 through 2025, respectively. In each such case, management believes such information presented represents the most recent data available to the Company.

Projections, assumptions and estimates of our future performance and the future performance of the industry in which we operate are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described in “Risk Factors” in this prospectus and Ortho Clinical Diagnostics Holdings plc’s Annual Report on Form 10-K for the fiscal year ended January 3, 2021 (“Ortho’s 2020 Form 10-K”). These and other factors could cause results to differ materially from those expressed in our estimates and beliefs and in the estimates prepared by independent parties.

Use of Non-GAAP Financial Measures

Adjusted EBITDA, Management EBITDA, Adjusted Net Income and Core revenue constant currency growth rate are our key non-GAAP financial measures. For more information about how we use these non-GAAP financial measures in our business, the limitations of these measures and a reconciliation of these measures to the most directly comparable GAAP measures, see “Prospectus Summary—Summary Consolidated Financial Data.” Adjusted EBITDA consists of net loss before interest expense, net, provision for (benefit from) income taxes and depreciation and amortization and eliminates (i) non-operating income or expense and (ii) impacts of certain non-cash, unusual or other items that are included in net loss that we do not consider indicative of our ongoing operating performance. Management EBITDA consists of Adjusted EBITDA plus certain other management adjustments. Adjusted Net Income consists of net loss before amortization and the elimination of (i) non-operating income or expense and (ii) impacts of certain non-cash, unusual or other items that are included in net loss that we do not consider indicative of our ongoing operating performance. Core revenue constant currency growth rate refers to the growth rate of revenue generated in our Clinical Laboratories and our Transfusion Medicine lines of business, which historically make up more than 95% of our net revenue, with any local currency revenue for all reporting periods translated into U.S. dollars using internally-derived foreign currency exchange rates held constant for each year. As needed, we translate prior periods based on our internally-derived currency exchange rates used for the current period in order to remove the impact of foreign currency exchange fluctuation.

We use these financial measures in the analysis of our financial and operating performance because they assist in the evaluation of underlying trends in our business. Additionally, Management EBITDA was the basis we used for assessing the profitability of our geographic-based reportable segments and was also utilized as a basis for calculating certain management incentive compensation programs through January 3, 2021. During the fiscal first quarter ended April 4, 2021, we changed the basis by which we measure segment profit or loss and calculate certain management incentive compensation programs from Management EBITDA to Adjusted EBITDA. In the case of Adjusted

iv

EBITDA and Adjusted Net Income, we believe that making such adjustments provides management and investors meaningful information to understand our operating performance and ability to analyze financial and business trends on a period-to-period basis. We believe that the presentation of these financial measures enhances an investor’s understanding of our financial performance. We use certain of these financial measures for business planning purposes and measuring our performance relative to that of our competitors.

Other companies in our industry may calculate Adjusted EBITDA, Management EBITDA, Adjusted Net Income and Core revenue constant currency growth rate differently than we do. As a result, these financial measures have limitations as analytical and comparative tools and you should not consider these items in isolation, or as a substitute for analysis of our results as reported under GAAP. Adjusted EBITDA, Management EBITDA and Adjusted Net Income should not be considered as measures of discretionary cash available to us to invest in the growth of our business. In calculating these financial measures, we make certain adjustments that are based on assumptions and estimates that may prove to have been inaccurate. In addition, in evaluating these financial measures, you should be aware that in the future we may incur expenses similar to those eliminated in the presentation of these metrics included in this prospectus. Our presentation of Adjusted EBITDA, Management EBITDA and Adjusted Net Income should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

Adjusted EBITDA, Management EBITDA, Adjusted Net Income and Core revenue constant currency growth rate have important limitations as analytical tools and you should not consider them in isolation or as substitutes for analysis of our results as reported under GAAP. Some of these limitations include the fact that:

• Adjusted EBITDA and Management EBITDA:

• do not reflect the significant interest expense on our debt, including the Senior Secured Credit Facilities, the 2025 Notes and the 2028 Notes;

• eliminate the impact of income taxes on our results of operations; and

• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA and Management EBITDA do not reflect any cash requirements for such replacements;

• Adjusted Net Income eliminates the effects of amortization related to purchased intangibles; and

• Core revenue constant currency growth rate eliminates the effects of foreign currency exchange rate fluctuations.

We compensate for these limitations by relying primarily on our GAAP results and using these financial measures only as a supplement to our GAAP results. For an explanation of the components of Core revenue constant currency growth rate, see footnotes (2) and (3) in “Prospectus summary—Summary consolidated financial data,” and for an explanation of the components of Adjusted EBITDA, Management EBITDA and Adjusted Net Income, see footnotes (4) and (5) in “Prospectus summary—Summary consolidated financial data.”

In calculating these financial measures, we make certain adjustments that are based on assumptions and estimates that may prove to have been inaccurate. In addition, in evaluating these financial measures, you should be aware that in the future we may incur expenses similar to those eliminated in this presentation. Our presentation of these metrics should not be construed as an inference that our future results will not be affected by unusual or non-recurring items or changes in our customer base. Additionally, our presentation of Adjusted EBITDA may differ from that included in the

v

Credit Agreement, the 2025 Notes Indenture and the 2028 Notes Indenture for purposes of covenant calculation.

PROSPECTUS SUMMARY

This prospectus summary highlights selected information contained or incorporated by reference in this prospectus and may not contain all of the information that you should consider in making your investment decision. For a more complete understanding of our company and this offering and before making any investment decision regarding our ordinary shares, you should read this entire prospectus and the information incorporated by reference, including “Risk Factors.”

Our Company

We are a pure-play in vitro diagnostics (“IVD”) business driven by our credo, “Because Every Test is A Life.” This guiding principle reflects the crucial role diagnostics play in global health and guides our priorities as an organization. As a leader in IVD, we impact approximately 800,000 patients every day. We are dedicated to improving outcomes for these patients and saving lives through providing innovative and reliable diagnostic testing solutions to the clinical laboratory and transfusion medicine communities. Our global infrastructure and commercial reach allow us to serve these markets with significant scale. We have an intense focus on the customer. We support our customers with high quality diagnostic instrumentation, a broad test portfolio and market leading service. Our products deliver consistently fast, accurate and reliable results that allow clinicians to make better-informed treatment decisions. Our business model generates significant recurring revenues and strong cash flow streams from ongoing sales of high margin consumables. In 2020, these consumables contributed approximately 93% of our total revenue. We maintain close connectivity with our customers through our global presence, with approximately 4,700 employees, including approximately 2,200 commercial sales, service and marketing teammates. This global organization allows us to support our customers across more than 130 countries and territories.

We have been pioneering life-impacting advances in diagnostics for over 80 years, from our earliest work in blood typing, to our innovation in infectious diseases and our latest developments in laboratory solutions. In 2014, we were acquired by The Carlyle Group from Johnson & Johnson and became an independent organization, solely focused on delivering high quality IVD products and service to our diagnostic customer base. At the time of the separation, our business had global scale, a reputation for high quality products, a strong quality management system and a research and development team with extensive scientific expertise. Over the past six years, we have significantly invested in our business with the objective of creating a highly efficient, innovative and lean organization capable of scaling to meet our customers’ needs. These investments included the following focus areas:

• Infrastructure:    We invested over $500 million in IT, finance, supply chain and other support functions to build out our infrastructure and capabilities as a standalone business and drive long-term, profitable growth.

• Research and development:    We increased our focus on innovation by investing over $650 million in research and development to enhance our existing capabilities and develop new instruments and assays to supplement our portfolio.

• Commercial:    We redesigned our go-to-market strategy across all key regions, expanded our sales force, implemented new customer information systems and launched ORTHOCARE to enhance our service capabilities.

• Operations:    We consolidated and streamlined our manufacturing capabilities and other global functions to improve profitability and cash flow, achieving more than $200 million in savings since our acquisition by Carlyle.

1

• Leadership:    To capitalize on these investments, we recruited a highly qualified management team of experienced diagnostic and healthcare leaders focused on our customers and accelerated growth.

With these investments, we have reinvigorated our portfolio, transformed our commercial model and emerged as a focused leader in the IVD market, which we believe positions our business for future growth.

IVD testing is a critical tool in evaluating health in many different settings around the world. IVD is a core component of routine health care check-ups for those who are presenting with symptoms or require procedures, and it influences up to 70% of critical healthcare clinical decision-making. Consequently, our IVD solutions have a profound impact on the assessment of health and the delivery of care. IVD is also critical in monitoring the transmission and spread of infectious disease outbreaks, where Ortho’s longstanding excellence in infectious disease testing is particularly relevant. Our solutions are central to the operations of hospitals, clinics, blood banks and donor centers around the world, where they are used to help diagnose certain conditions, such as cancer or heart attacks, and infectious diseases, such as hepatitis, HIV, and most recently, COVID-19, where we have launched two antibody tests and an antigen test, and we are actively expanding our menu of tests to address the global pandemic.

We operate in an approximately $27 billion addressable market, which is expected to grow at a compound annual growth rate (“CAGR”) of approximately 5% from 2020 to 2025. We compete in the two largest IVD markets, Immunoassay and Clinical Chemistry, which together comprise our Clinical Laboratories business and represent approximately $25 billion of our current addressable market. We expect our Clinical Laboratories business will be favorably impacted by an aging population, an increased need for testing of chronic conditions, the expansion of access to healthcare services, the emergence of new disease states and other macro trends. We are also the global leader in Transfusion Medicine, which includes hospital-based Immunohematology and Donor Screening for blood and plasma at hospitals and other donation centers. Transfusion Medicine represents approximately $2 billion of our current addressable market. We expect our Transfusion Medicine business will be favorably impacted by increases in the number and type of surgical procedures, an aging population and other macro trends. There is significant overlap in our customer base given we currently sell to about 70% of the hospitals in the United States, and we are often able to leverage our leadership within Transfusion Medicine to cross-sell our Clinical Laboratories solutions. Because we focus primarily on acute or critical care diagnostics that are core to therapeutic decisions in hospitals, our markets are relatively resilient across business cycles. We offer our products and services globally, with distinct offerings targeted to the needs of customers in developed and emerging markets.

Today, we operate two lines of business, Clinical Laboratories and Transfusion Medicine, which together generate our core revenue:

• Clinical Laboratories:    Comprised of Clinical Chemistry, which is the measurement of target chemicals in bodily fluids for the evaluation of health and the clinical management of patients, and Immunoassay, which is the measurement of proteins as they act as antigens in the spread of disease, antibodies in the immune response spurred by disease, or markers of proper organ function and health.

• Transfusion Medicine:    Comprised of Donor Screening, where blood and plasma is screened at donation for blood type and target diseases, and Immunohematology, where blood is typed and screened at the hospital blood bank before being transfused into the patient.

2

Our broad offerings allow us to support our customer base and maximize the opportunity to provide each of our customers with a comprehensive array of products and services over time. We refer to this mutually beneficial approach as focusing on Lifetime Customer Value (“LCV”). Our focus on LCV underpins everything we do, from the design and execution of our commercial and service model, to our instrument and assay innovation, to the composition of our global footprint. Our approach has informed our choice to focus on medium- to high-volume laboratories, which in turn has helped us become a focused leader in our selected markets and transformed our financial profile. We intend to continue to invest in and evolve our LCV framework to best support our customers and maximize our financial results.

As an example, we may begin a Clinical Laboratories customer relationship by providing a standalone instrument (often a clinical chemistry analyzer) and a set of assays that are relevant to that customer’s specific testing needs. As the customer and its testing needs grow, we look to migrate the customer, where appropriate, to an integrated analyzer that performs both clinical chemistry and immunoassay testing. This migration helps us increase our customers’ testing capabilities as well as the revenue we generate from customers. For our larger customers, we ultimately may expand their testing throughput by installing automation tracks that connect multiple analyzers along the automation track, while providing the full suite of our ever-expanding assay menu. As we have significantly expanded our test menu offering, our integrated analyzers are now more often where our Clinical Laboratories relationship starts. In Transfusion Medicine, the life cycle is similar, as customers graduate from manual testing processes to semi-automated capabilities to fully-automated blood and plasma screening instrumentation as their testing volumes and technical competencies grow over time. We focus on building long-term customer relationships and continuing to enhance both our offering and the customer’s ability to care for their patients—ultimately deepening our commercial relationship and driving our financial model.

We believe that the strong clinical performance of our assays, our instruments’ ease-of-use and reliability, our best-in-class customer service and low total cost of ownership contribute to our high revenue retention rate of approximately 98% in 2020. We have longstanding relationships with customers, with an average Clinical Laboratories customer relationship of almost 13 years and an average Transfusion Medicine customer relationship of almost 15 years. Our customer relationships are particularly strong in the medium- to high-volume laboratories (our “Focus Markets”), which compares to the broader market that includes low- and ultra high-volume laboratories. In addition, our dry slide technology has an environmentally friendly profile as it doesn’t require water system plumbing, it reduces hazardous waste and it requires less space for liquid storage. All of these attributes resonate particularly well with customers who are pursuing environmental goals or customers who operate in regions with scarce water supply.

Our revenue is driven by a “razor-razor blade” business model. Through this model, we generally sell or place instruments under long-term contracts, which support the ongoing sale of our assays, reagents and consumables. Our instruments are closed systems, requiring customers to purchase the assays, reagents and consumables from us. These sales generate a high proportion of recurring revenues. As of July 4, 2021, we had an installed base of approximately 20,300 instruments, which increased approximately 4% since June 28, 2020. We also generate non-core revenue, including through our contract manufacturing business and certain business collaborations, which accounted for approximately 3% of our net revenue during the fiscal year ended January 3, 2021. During the fiscal year ended January 3, 2021, we recorded net revenue of $1,766.2 million, net loss of $211.9 million and Adjusted EBITDA of $456.0 million. During the fiscal six months ended July 4, 2021, we recorded net revenue of $999.3 million, net loss of $59.1 million and Adjusted EBITDA of $280.6 million. As of July 4, 2021, we had total indebtedness of $2,295.0 million, and for the fiscal six months ended July 4,

3

2021, our interest expense was $76.4 million. We note that our net revenue for the fiscal six months ended July 4, 2021 was 25.2% higher as compared to the prior year period, mainly driven by our core lines of business, as we recorded higher revenues in all geographic segments of our Clinical Laboratories business, and in certain geographic segments of our Transfusion Medicine business as well as a positive impact from foreign currency fluctuations, which was primarily driven by the weakening of the U.S. dollar against a variety of currencies, primarily the Euro, British Pound and Chinese Yuan, partially offset by the strengthening of the Brazilian Real. We note that our net revenue for the 2020 fiscal year was impacted by the global COVID-19 pandemic primarily due to decreased shipments to customers, most notably during the fiscal second quarter ended June 28, 2020. However, during the fiscal third quarter ended September 27, 2020, we began to experience a rebound towards the positive quarterly trajectory we saw prior to the beginning of the pandemic. As an example of such quarterly trajectory, during the four quarters prior to the fiscal second quarter ended June 28, 2020, our quarterly core revenue (excluding local HCV) was growing in the range of approximately 3.8% to 5.8% on a constant currency basis as compared to the relevant prior year period. Beginning in the fiscal third quarter ended September 27, 2020, and continuing through the fiscal second quarter ended July 4, 2021, we have returned to growth in our core revenue (excluding local HCV) on a constant currency basis, most recently increasing 25.0% during the fiscal second quarter ended July 4, 2021 as compared to the prior year period.

Our Competitive Strengths

We believe we are well-positioned to drive sustained and profitable growth through our relentless focus on LCV. This customer-centric approach informs the execution of our commercial and service model and underpins our go-to-market strategy.

(3) When we use the term “constant currency,” it means that we have translated current period and prior period amounts from local currency to U.S. dollars using internally-derived currency exchange rates held constant for each year. As needed, we translate prior periods based on our internally-derived currency exchange rates used in the current period in order to remove the impact of foreign currency exchange fluctuation. This additional non-GAAP financial information is not meant to be considered in isolation from or as substitute for financial information prepared in accordance with GAAP. The following table reconciles core revenue to core revenue constant currency growth rate for the periods presented:

(4) Adjusted EBITDA consists of net loss before interest expense, net, provision for (benefit from) income taxes and depreciation and amortization and eliminates (i) non-operating income or expense and (ii) impacts of certain non-cash, unusual or other items that are included in net loss that we do not consider indicative of our ongoing operating performance. Management EBITDA consists of Adjusted EBITDA plus certain other management adjustments and was the basis we used for assessing the profitability of our geographic-based reportable segments. Additionally, Management EBITDA was utilized as a basis for calculating certain management incentive compensation programs. Beginning in the fiscal first quarter ended April 4, 2021, we began using Adjusted EBITDA as the basis for assessing the profitability of our geographic-based reportable segments and as a basis for calculating certain management incentive compensation programs. Adjusted Net Income consists of net loss before amortization and the elimination of (i) non-operating income or expense and (ii) impacts of certain non-cash, unusual or other items that are included in net loss that we do not consider indicative of our ongoing operating performance. In the case of Adjusted EBITDA and Adjusted Net Income, we believe that making such adjustments provides management and investors meaningful information to understand our operating performance and ability to analyze financial and business trends on a period-to-period basis.

(5) Adjusted EBITDA, Management EBITDA, Adjusted Net Income and Core revenue constant currency growth rate are not calculated or presented in accordance with GAAP and other companies in our industry may calculate Adjusted EBITDA, Management EBITDA, Adjusted Net Income and Core revenue constant currency growth rate differently than we do. As a result, these financial measures have limitations as analytical and comparative tools and you should not consider these items in isolation, or as a substitute for analysis of our results as reported under GAAP. Adjusted EBITDA, Management EBITDA and Adjusted Net Income should not be considered as measures of discretionary cash available to us to invest in the growth of our business. In calculating these financial measures, we make certain adjustments that are based on assumptions and estimates that may prove to have been inaccurate. In addition, in evaluating these financial measures, you should be aware that in the future we may incur expenses similar to those eliminated in this presentation. Our presentation of Adjusted EBITDA, Management EBITDA and Adjusted Net Income should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. For additional information regarding Adjusted EBITDA, Management EBITDA, Adjusted Net Income and Core revenue constant currency growth rate and our use and presentation of those measures and the related risks, see “Use of Non-GAAP Financial Measures.”

The following tables reconcile net loss to Adjusted EBITDA, Management EBITDA and Adjusted Net Income for the periods presented:

(a) Represents noncash unrealized gains and losses resulting from the remeasurement of transactions denominated in foreign currencies primarily related to intercompany loans. In the fiscal first quarter ended April 4, 2021, we initiated programs to mitigate the impact of foreign currencies related to intercompany loans in our results, and such non-cash net unrealized gains were approximately $13.8 million for the fiscal six months ended July 4, 2021. We expect these programs to continue to mitigate the impact of foreign currencies related to intercompany loans in our results of operations in future periods, and thus we did not exclude non-cash unrealized gains and losses resulting from the remeasurement of transactions denominated in foreign currencies from Adjusted EBITDA and Adjusted Net Income during the fiscal six months ended July 4, 2021 and onwards.

(b) Represents restructuring and severance costs related to several discrete initiatives intended to strengthen operational performance and to support building our commercial capabilities including a project announced in fiscal year ended January 3, 2016 to outsource equipment manufacturing operations in Rochester, New York and a project announced in fiscal year ended December 30, 2018 to transfer certain production lines among facilities.

(c) Represents stock-based compensation expense, including the impact of modifications to our stock option agreement of $6.0 million during the fiscal six months ended July 4, 2021 and $14.7 million during the fiscal year ended December 29, 2019.

(d) Represents the reversal of the impact of tax indemnification income with Johnson & Johnson, primarily related to certain state tax matters, for which we recorded a tax reserve and indemnification expense. These state tax matters primarily include the taxability of the sale of our assets on the Acquisition date from Johnson & Johnson. Additionally, during the fiscal second quarter ended June 30, 2019, we recorded indemnification expense related to the release of certain tax reserves upon the settlement of certain state tax matters that were settled for an amount lower than what we had estimated.

(e) Represents an initial, non-refundable upfront payment made to Quotient Ltd. (“Quotient”), one of our partners and suppliers. See note 9 to our unaudited consolidated financial statements and note 13 to our audited consolidated financial statements incorporated by reference in this prospectus for further discussion of the Quotient relationship.

(g) Represents realized foreign currency losses (gains), impact from adoption of accounting standards, costs in connection with COVID-19 and other immaterial management adjustments. During the fiscal first quarter ended April 4, 2021, we changed our measure of the profitability of our geographic-based reportable segments and basis for calculating certain management incentive compensation programs from Management EBITDA to Adjusted EBITDA. Accordingly, Management EBITDA for the fiscal six months ended July 4, 2021 and June 28, 2020 has not been separately presented.

(h) Non-GAAP adjustments were tax effected based on the nature of the expense and related jurisdiction, many of which are impacted by valuation allowances resulting in little to no tax impact.

(i) We exclude deferred tax resulting from changes in tax law and expiration of statutes, adjustments for uncertain tax positions, and other unusual items not related to current operating results.

(6) Adjusted EBITDA margin is defined as Adjusted EBITDA as a percentage of net revenue.

RISK FACTORS

Investing in our ordinary shares involves a high degree of risk. You should carefully consider the following risk factors together with all of the other information included or incorporated by reference in this prospectus, including our consolidated financial statements and related notes incorporated by reference herein, before deciding whether to invest in our ordinary shares. The occurrence of any of the events described below could harm our business, financial condition, results of operations and growth prospects. In such an event, the trading price of our ordinary shares may decline and you may lose all or part of your investment.

Risks Related to this Offering and Ownership of Our Ordinary Shares

The market price of our ordinary shares has been volatile and may continue to fluctuate substantially, which could result in substantial losses for purchasers of our ordinary shares.

The trading price of our ordinary shares has been and is likely to continue to be volatile. The stock market has experienced extreme volatility. This volatility often has been unrelated or disproportionate to the operating performance of particular companies. The market price of our ordinary shares has been highly volatile and may continue to fluctuate substantially due to a number of factors such as those listed in “Risk Factors” in this prospectus and in the documents incorporated by reference herein and the following:

• results of operations that vary from the expectations of securities analysts and investors;

• results of operations that vary from those of our competitors;

• changes in expectations as to our future financial performance, including financial estimates and investment recommendations by securities analysts and investors;

• declines in the market prices of stocks generally;

• strategic actions by us or our competitors;

• announcements by us or our competitors of significant contracts, new products, acquisitions, joint marketing relationships, joint ventures, other strategic relationships or capital commitments;

• changes in general economic or market conditions or trends in our industry or markets;

• changes in business or regulatory conditions;

• additions or departures of key management personnel;

• future sales of our ordinary shares or other securities by us or our existing shareholders, or the perception of such future sales;

• investor perceptions of the investment opportunity associated with our ordinary shares relative to other investment alternatives;

• the public’s response to press releases or other public announcements by us or third parties, including our filings with the SEC;

• announcements relating to litigation;

• guidance, if any, that we provide to the public, any changes in this guidance or our failure to meet this guidance;

• the development and sustainability of an active trading market for our ordinary shares;

• changes in accounting principles; and

17

• other events or factors, including those resulting from natural disasters, war, acts of terrorism or responses to these events.

These broad market and industry fluctuations may materially adversely affect the market price of our ordinary shares, regardless of our actual operating performance. In addition, price volatility may be greater if the public float and trading volume of our ordinary shares are low.

In the past, following periods of market volatility, shareholders have instituted securities class action litigation. If we were involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from our business regardless of the outcome of such litigation.

Our quarterly operating results fluctuate and may fall short of prior periods, our projections or the expectations of securities analysts or investors, which could materially adversely affect the price of our ordinary shares.

Our operating results have fluctuated from quarter to quarter at points in the past, and they may do so in the future. Therefore, results of any one fiscal quarter are not a reliable indication of results to be expected for any other fiscal quarter or for any year. If we fail to increase our results over prior periods, to achieve our projected results or to meet the expectations of securities analysts or investors, the price of our ordinary shares may decline, and the decrease in the price of our ordinary shares may be disproportionate to the shortfall in our financial performance. Results may be affected by various factors, including those described in these risk factors. We maintain a forecasting process that seeks to align expenses to backlog conversion. If we do not control costs or appropriately adjust costs to actual results, or if actual results differ significantly from our forecast, our financial performance could be materially adversely affected.

We are a holding company with no operations and may not have access to sufficient cash to meet our financial obligations.

We are a holding company and have limited direct operations. Our most significant assets are the equity interests we directly and indirectly hold in our subsidiaries. As a result, we are dependent upon dividends and other payments from our subsidiaries to generate the funds necessary to meet our outstanding debt service and other obligations and such dividends may be restricted by law or the instruments governing our indebtedness, including the Credit Agreement, the 2028 Notes Indenture, the 2025 Notes Indenture or other agreements of our subsidiaries. Our subsidiaries may not generate sufficient cash from operations to enable us to meet our financial obligations. In addition, our subsidiaries are separate and distinct legal entities and may be legally or contractually prohibited or restricted from paying dividends or otherwise making funds available to us. In addition, payments to us by our subsidiaries will be contingent upon our subsidiaries’ earnings. Additionally, we may be limited in our ability to cause any future collaborative arrangements under which our subsidiaries distribute their earnings to us. Subject to certain qualifications, our subsidiaries are permitted, under the terms of our indebtedness, to incur additional indebtedness that may restrict payments from those subsidiaries to us. We cannot assure you that agreements governing the current and future indebtedness of our subsidiaries will permit those subsidiaries to provide us with sufficient cash to fund our financial obligations.

We currently do not intend to declare dividends on our ordinary shares in the foreseeable future and, as a result, your only opportunity to achieve a return on your investment is if the price of our ordinary shares appreciates.

We currently do not expect to declare any dividends on our ordinary shares in the foreseeable future. Instead, we anticipate that all of our earnings in the foreseeable future will be used to provide

18

working capital, to support our operations and to finance the growth and development of our business. Any determination to declare or pay dividends in the future will be at the discretion of our board of directors, subject to applicable laws and dependent upon a number of factors, including our earnings, capital requirements and overall financial conditions. In addition, because we are a holding company, our ability to pay dividends on our ordinary shares may be limited by restrictions on our ability to obtain sufficient funds through dividends from subsidiaries, including restrictions under the covenants of the Credit Agreement, the 2025 Notes Indenture and the 2028 Notes Indenture, and may be further restricted by the terms of any future debt or preferred securities. Accordingly, your only opportunity to achieve a return on your investment in our company may be if the market price of our ordinary shares appreciates and you sell your ordinary shares at a profit. The market price for our ordinary shares may never exceed, and may fall below, the price that you pay for such ordinary shares.

If securities analysts do not publish research or reports about our business or if they downgrade our stock or our sector, our stock price and trading volume could decline.

The trading market for our ordinary shares relies in part on the research and reports that industry or financial analysts publish about us or our business or industry. We do not control these analysts. Furthermore, if one or more of the analysts who do cover us downgrade our stock or our industry, or the stock of any of our competitors, or publish inaccurate or unfavorable research about our business or industry, the price of our shares could decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, we could lose visibility in the market, which in turn could cause our share price or trading volume to decline.

Future sales, or the perception of future sales, by us or our existing shareholders in the public market following this offering could cause the market price for our ordinary shares to decline.

After this offering, the sale of our ordinary shares in the public market, or the perception that such sales could occur, could harm the prevailing market price of our ordinary shares. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

Our directors, our executive officers and certain significant equity holders have entered into lock-up agreements in connection with this offering, on substantially similar terms, which expire 90 days from the date of this prospectus. Upon completion of this offering, based on the number of ordinary shares outstanding on September 1, 2021, 122,176,446 of our ordinary shares (assuming no exercise of the underwriters’ option to purchase additional ordinary shares) will be restricted from sale as a result of lock-up agreements with the underwriters through the date that is 90 days from the date of this prospectus. Among other exceptions, the lock-up agreements entered into in connection with this offering permit our directors and executive officers to sell ordinary shares pursuant to existing trading plans pursuant to Rule 10b5-1 under the Exchange Act. Such sales could occur at any time, and could be substantial. See “Underwriting” for a description of the material terms of these lock-up agreements.

After this offering, the holders of an aggregate of 121,406,000 of our ordinary shares (assuming no exercise of the underwriters’ option to purchase additional ordinary shares), will have rights, subject to some conditions, to require us to file registration statements covering their ordinary shares or to include their ordinary shares in registration statements that we may file for ourselves or our shareholders. Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the Securities Act, except for shares held by our affiliates as defined in Rule 144 under the Securities Act. See “Shares Eligible for Future Sale.”

As restrictions on resale end or if these shareholders exercise their registration rights, the market price of our ordinary shares could drop significantly if the holders of these shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of our ordinary shares or other securities.

19

In addition, our ordinary shares reserved for future issuance under our 2021 Incentive Award Plan will become eligible for sale in the public market once those ordinary shares are issued, subject to provisions relating to various vesting agreements, lock-up agreements and Rule 144 under the Securities Act, as applicable. As of July 4, 2021, a total of 7,864,810 ordinary shares have been reserved for future issuance under the 2021 Incentive Award Plan (including shares subject to existing equity awards), which amount will increase on the first day of the fiscal year for up to 10 years by an amount equal to 3% of the ordinary shares outstanding on the last day of the prior fiscal year or such lesser amount as may be determined by our board of directors.

In the future, we may also issue our securities in connection with investments or acquisitions. The amount of our ordinary shares issued in connection with an investment or acquisition could constitute a material portion of our then-outstanding ordinary shares. Any issuance of additional securities in connection with investments or acquisitions may result in additional dilution to you.

Provisions in our organizational documents could delay or prevent a change of control.

Certain provisions of our articles of association and shareholders agreement may have the effect of delaying or preventing a merger, acquisition, tender offer, takeover attempt or other change of control transaction that a shareholder might consider to be in its best interest, including attempts that might result in a premium over the market price of our ordinary shares.

Subject to the provisions of the U.K. Companies Act 2006, these provisions provide for, among other things:

• the division of our board of directors into three classes, as nearly equal in size as possible, with directors in each class serving three-year terms and with terms of the directors of only one class expiring in any given year;

• the reappointment of any member of our board of directors initially appointed by the Principal Shareholder in the event such director is removed in accordance with our articles of association and pursuant to the UK Companies Act 2006;

• the ability of our board of directors to issue one or more series of preferred shares with voting or other rights or preferences that could have the effect of impeding the success of an attempt to acquire us or otherwise effect a change of control;

• advance notice for nominations of directors by shareholders and for shareholders to include matters to be considered at shareholder meetings;

• the right of the Principal Shareholder and certain of its respective affiliates to appoint the majority of the members of our board of directors for so long as the Principal Shareholder beneficially owns at least 25% of our ordinary shares, and such appointed members will serve as directors without standing for election by our shareholders;

• certain limitations on convening special shareholder meetings; and

• that certain provisions of our articles of association may be amended only with the consent of the Principal Shareholder for so long as the Principal Shareholder beneficially owns at least 5% of our ordinary shares.

These provisions could make it more difficult for a third party to acquire us, even if the third-party’s offer may be considered beneficial by many of our shareholders. As a result, our shareholders may be limited in their ability to obtain a premium for their ordinary shares. See “Description of Share Capital and Articles of Association.”

20

Private equity investment funds affiliated with the Principal Shareholder will continue to own a significant percentage of our equity after this offering and their interests may not be aligned with yours.

Upon the completion of this offering, the Principal Shareholder will own approximately 51.3% of our ordinary shares, or approximately 49.9% if the underwriters exercise in full their option to purchase additional ordinary shares, and will have the power to control or influence our affairs and policies. The Principal Shareholder will also control, to a large degree, the election of directors, the appointment of management, the entry into mergers, sales of substantially all of our assets and other extraordinary transactions. The directors so elected have authority to issue additional shares, implement stock repurchase programs, declare interim dividends and recommend final dividends, and make other decisions. The interests of the Principal Shareholder could conflict with your interests. For example, the Principal Shareholder may also have an interest in pursuing acquisitions, divestitures, financings or other transactions that, in its judgment, could enhance its equity investments. Additionally, the Principal Shareholder is in the business of making investments in companies, and may from time to time acquire interests in businesses that directly or indirectly compete with certain portions of our business or are suppliers or customers of ours.

We are a “controlled company” within the meaning of Nasdaq rules and the rules of the SEC. As a result, we qualify for, and rely on, exemptions from certain corporate governance requirements that provide protection to shareholders of other companies.

The Principal Shareholder owns, and, upon completion of this offering, will continue to own, a majority of our outstanding ordinary shares. As a result, we are a “controlled company” within the meaning of the corporate governance standards of Nasdaq. Under these rules, a company of which more than 50% of the voting power is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain corporate governance requirements, including:

• the requirement that a majority of our board of directors consist of “independent directors” as defined under the rules of Nasdaq;

• the requirement that we have a compensation committee that is composed entirely of directors who meet the Nasdaq independence standards for compensation committee members; and

• the requirement that our director nominations be made, or recommended to our full board of directors, by our independent directors or by a nominations committee that consists entirely of independent directors.

We currently rely on certain of the exemptions listed above. As a result, we may not have a majority of independent directors, our nominations committee and compensation committee will not consist entirely of independent directors and such committees may not be subject to annual performance evaluations. Accordingly, you will not have the same protections afforded to shareholders of companies that are subject to all of the corporate governance requirements of Nasdaq.

Failure to comply with requirements to design, implement and maintain effective internal controls could have a material adverse effect on our business and the price of our ordinary shares.

As a privately-held company, we were not required to evaluate our internal controls over financial reporting in a manner that meets the standards of publicly traded companies required by Section 404(a) of the Sarbanes-Oxley Act of 2002 (“Section 404” and the “Sarbanes-Oxley Act,” respectively). As a public company, we have significant requirements for enhanced financial reporting and internal controls. The process of designing and implementing effective internal controls that we

21

manage 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 are required, pursuant to Section 404, to furnish a report by management on, among other things, the effectiveness of our internal controls over financial reporting in our annual report on Form 10-K for the year ending January 2, 2022. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal controls over financial reporting. The rules governing the standards that must be met for our management to assess our internal controls over financial reporting are complex and require significant documentation, testing and possible remediation. Testing internal controls may divert our management’s attention from other matters that are important to our business.

In connection with the implementation of the necessary procedures and practices related to internal controls 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. 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 attestation report. While not required for our annual report on Form 10-K for the year ending January 2, 2022, our independent registered public accounting firm may be required to issue an attestation report on the effectiveness of internal controls over financial reporting in our annual report on Form 10-K for a fiscal year thereafter.

Our testing, or the subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses. A material weakness in internal controls could result in our failure to detect a material misstatement of our annual or quarterly consolidated financial statements or disclosures. We may not be able to conclude on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404. If we are unable to conclude that we have effective internal controls over financial reporting, investors could lose confidence in our reported financial information, which could have a material adverse effect on the trading price of our ordinary shares.

Our board of directors is authorized to issue and designate preferred shares in additional series without shareholder approval.

Our articles of association authorize our board of directors, without the approval of our shareholders, to issue preferred shares, subject to limitations prescribed by applicable law, rules and regulations and the provisions of our articles of association, as preferred shares in series, to establish from time to time the number of preferred shares to be included in each such series and to fix the designation, powers, preferences and rights of the preferred shares of each such series and the qualifications, limitations or restrictions thereof. The powers, preferences and rights of these additional series of preferred shares may be senior to or on parity with our ordinary shares, which may reduce their value.

Our articles of association include exclusive jurisdiction and forum selection provisions, which may impact the ability of shareholders to bring actions against us or increase the costs of bringing such actions.

Our articles of association provide that the courts of England and Wales shall have exclusive jurisdiction to determine any and all disputes brought by a shareholder in their capacity as a shareholder against us, our officers or our board of directors arising out of or in connection with our

22

articles of association or any non-contractual obligations arising out of or in connection with our articles of association, or otherwise. In addition, our articles of association provide that if a court were to find such provision invalid or unenforceable with respect to any complaint asserting a cause of action arising under the Securities Act, the federal courts of the United States will be the exclusive forum for resolving any such complaint. These limitations on the forum in which shareholders may initiate action against us may limit a shareholder’s ability to bring a claim in a judicial forum that it finds favorable and could increase the costs and inconvenience of pursuing claims or otherwise adversely affect a shareholder’s ability to seek monetary or other relief.

A court could decline to enforce these exclusive jurisdiction and forum provisions. If a court were to find these provisions to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions.

USE OF PROCEEDS

The selling shareholder is offering all of the ordinary shares in this offering, including any shares to be sold if the underwriters exercise their option to purchase additional shares, and will receive all of the net proceeds from the sale of ordinary shares in this offering. We are not offering any ordinary shares under this prospectus and will not receive any proceeds from the sale of ordinary shares by the selling shareholder.

27

DIVIDEND POLICY

We currently do not expect to declare any dividends on our ordinary shares in the foreseeable future. Instead, we anticipate that all of our earnings in the foreseeable future will be used to provide working capital, support our operations, finance the growth and development of our business and reduce our net debt. Any determination to declare dividends in the future will be at the discretion of our board of directors, subject to applicable laws, and will be dependent on a number of factors, including our earnings, capital requirements and overall financial condition. We are controlled by the Principal Shareholder, who has the ability to appoint a majority of the members of our board of directors and therefore control the payment of dividends. In addition, because we are a holding company, our ability to pay dividends on our ordinary shares may be limited by restrictions on our ability to obtain sufficient funds through dividends from subsidiaries, including restrictions under the covenants of the Credit Agreement, the 2025 Notes Indenture and the 2028 Notes Indenture, and may be further restricted by the terms of any future debt or preferred securities. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and capital resources—Debt capitalization” in Ortho’s 2020 Form 10-K and Ortho’s 2021 Q2 Form 10-Q, which are incorporated by reference in this prospectus, for more information about our Senior Secured Credit Facilities and our Senior Notes.

DESCRIPTION OF SHARE CAPITAL AND ARTICLES OF ASSOCIATION

General

We were incorporated as a public limited company under the laws of England and Wales with the legal name Ortho Clinical Diagnostics Holdings plc on December 16, 2020, with company number 13084624. Our registered office is Felindre Meadows, Pencoed, Bridgend, Mid Glamorgan, Wales, CF35 5PZ. The principal legislation under which we operate and our ordinary shares are issued is the U.K. Companies Act 2006.

Share Capital

As of July 4, 2021, our issued share capital was $2,349.21. The nominal value of our ordinary shares is $0.00001 per ordinary share. Each issued ordinary share is fully paid.

Options

As of July 4, 2021, there were options to purchase 15,857,759 ordinary shares outstanding with a weighted average exercise price of $9.76 per ordinary share.

Ordinary Shares

The following summarizes the rights of holders of our ordinary shares:

• each holder of our ordinary shares is entitled to one vote per ordinary share at a meeting of shareholders;

• the holders of the ordinary shares shall be entitled to receive notice of, attend, speak, and vote at our general meetings; and

• holders of our ordinary shares are entitled to receive such dividends as are recommended by our directors and declared by our shareholders.

Registered Shares

We are required by the U.K. Companies Act 2006 to keep a register of our shareholders. Under English law, the ordinary shares are deemed to be issued when the name of the shareholder is entered in our share register. The share register therefore is prima facie evidence of the identity of our shareholders and the ordinary shares that they hold. The share register generally provides limited, or no, information regarding the ultimate beneficial owners of our ordinary shares. Our share register is maintained by our registrar, Computershare Trust Company N.A.

Under the U.K. Companies Act 2006, we must enter an allotment of ordinary shares in our share register as soon as practicable and in any event within two months of the allotment. We will perform all procedures necessary to update the share register to reflect the ordinary shares being sold in an offering. We also are required by the U.K. Companies Act 2006 to register a transfer of ordinary shares (or give the transferee notice of and reasons for refusal) as soon as practicable and in any event within two months of receiving notice of the transfer.

We, any of our shareholders or any other affected person may apply to the court for rectification of the share register if:

• the name of any person, without sufficient cause, is wrongly entered in or omitted from our register of members; or

33

• there is a default or unnecessary delay in entering on the register the fact of any person having ceased to be a member or on which we have a lien, provided that such refusal does not prevent dealings in the ordinary shares taking place on an open and proper basis.

Preemptive Rights

English law generally provides shareholders with preemptive rights when new shares are issued for cash; however, it is possible for the articles of association, or shareholders in a general meeting, to exclude preemptive rights. Such an exclusion of preemptive rights may be for a maximum period of up to five years from the date of adoption of the articles of association, if the exclusion is contained in the articles of association, or from the date of the shareholder resolution, if the exclusion is by shareholder resolution. In either case, this exclusion would need to be renewed by our shareholders upon its expiration (i.e., at least every five years). In connection with our initial public offering, our shareholders approved the exclusion of preemptive rights for a period of five years from the date of the approval in respect of the allotment of up to a maximum amount of one billion ordinary shares, which exclusion will need to be renewed upon expiration (i.e., at least every five years) to remain effective, but may be sought more frequently for additional five-year terms (or any shorter period).

Articles of Association

The following is a description of our articles of association.

Shares and Rights Attaching to Them

Objects

The objects of our company are unrestricted.

Share Rights

Subject to any special rights attaching to shares already in issue, our shares may be issued with or have attached to them any rights or restrictions as we may resolve by ordinary resolution of the shareholders or so far as the resolution does not make specific provision, as the board may determine.

Voting Rights

Without prejudice to any special rights, privileges or restrictions as to voting rights attached to any shares forming part of our share capital from time to time, all votes at a general meeting shall be taken on a poll and each holder of the shares of the class shall, on a poll, have one vote in respect of every share of the class held by them.

Restrictions on Voting

No shareholder shall be entitled to vote at any general meeting in respect of any share held by him unless all sums payable by him in respect of that share have been paid.

The board may from time to time make calls upon the shareholders in respect of any money unpaid on their shares and each shareholder shall (subject to at least 14 days’ notice specifying when and how the payment is to be made) pay at the time or times so specified the amount called on his shares.

34

Dividends

We may by ordinary resolution of the shareholders declare dividends out of profits available for distribution in accordance with the respective rights of shareholders but no such dividend shall exceed the amount recommended by the directors. The board may from time to time pay shareholders such interim dividends as appear to the board to be justified by our financial position but, if at any time, our share capital is divided into different classes the board may not pay such interim dividends in respect of those shares which confer on the holders thereof deferred or non-preferential rights with regard to dividends if, at the time of payment, any preferential dividend is in arrears.

Subject to any special rights attaching to or the terms of issue of any share, all dividends shall be declared and paid according to the amounts paid up on the ordinary shares and shall be apportioned and paid pro rata according to the amounts paid up on the ordinary shares during any part or parts of the period in respect of which the dividend is paid.

No dividend or other moneys payable by us on or in respect of any share shall bear interest against us unless otherwise provided by the rights attached to the share or the provisions of another agreement between the shareholder and us. Any dividend unclaimed after a period of 12 years from the date such dividend became due for payment shall be forfeited and cease to remain owing.

Dividends may be declared or paid in any currency and the board may decide the rate of exchange for any currency conversions that may be required, and how any costs involved are to be met, in relation to the currency of any dividend.

Any general meeting declaring a dividend may by ordinary resolution of shareholders, upon the recommendation of the board, direct payment or satisfaction of such dividend wholly or in part by the distribution of non-cash assets of equivalent value, including shares or other securities in any company.

The directors may, if authorized by an ordinary resolution of shareholders, offer any holders of ordinary shares the right to elect to receive in lieu of a dividend, or part of a dividend, an allotment of ordinary shares credited as fully paid up.

Change of Control

Our articles of association contain provisions that are intended to enhance the likelihood of continuity and stability in the composition of our board of directors. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile change of control and enhance the ability of our board of directors to maximize shareholder value in connection with any unsolicited offer to acquire us. However, these provisions may have the effect of delaying, deterring or preventing a merger or acquisition of our company by means of a tender offer, a proxy contest or other takeover attempt that a shareholder might consider in its best interest, including attempts that might result in a premium over the prevailing market price for the ordinary shares held by shareholders.

Distributions on Winding Up

If we are in liquidation, the liquidator may, if authorized by a special resolution of shareholders and any other authority required at law, divide among shareholders (excluding us to the extent we are a shareholder by virtue only of holding treasury shares) in specie or in kind the whole or any part of our assets (whether or not the assets consist of property of one kind or consist of properties of different kinds and the liquidator may for such purpose set such value as the liquidator deems fair upon any one or more class or classes of property and may determine how such division shall be carried out as

35

between the shareholders or different classes of shareholders), or vest the whole or any part of such assets in trustees upon such trusts for the benefit of the shareholders as the liquidator determines (and the liquidation of the Company may be closed and the Company dissolved), but no shareholder shall be compelled to accept any shares or other assets upon which there is any liability or potential liability.

Variation of Rights

All or any of the rights and privileges attached to any class of shares issued may be varied or abrogated only with the consent in writing of the holders of not less than three-fourths in nominal value of the issued shares of that class (excluding any shares held as treasury shares) or by special resolution passed at a separate general meeting of the holders of such shares, subject to the other provisions of the U.K. Companies Act 2006 and the terms of their issue. The U.K. Companies Act 2006 also provides a right to object to the variation of the share capital by the shareholders who did not vote in favor of the variation. Should 15% or more of the shareholders of the issued shares in question apply to the court to have the variation cancelled, the variation shall have no effect unless and until it is confirmed by the court.

Alteration to Share Capital

We may, by ordinary resolution of shareholders, consolidate all or any of our share capital into shares of larger amount than our existing shares, or sub-divide our shares or any of them into shares of a smaller amount. We may, by special resolution of shareholders, confirmed by the court, reduce our share capital or any capital redemption reserve or any share premium account in any manner authorized by the U.K. Companies Act 2006. We may redeem or purchase all or any of our shares as described in “—Other U.K. Law Considerations—Purchase of own shares.”

Preemption Rights

In certain circumstances, our shareholders may have statutory preemption rights under the U.K. Companies Act 2006 in respect of the allotment of new shares as described in “—Preemptive Rights” and “—Differences in Corporate Law—Pre-emptive rights” in this prospectus.

Transfer of Shares

Any shareholder holding shares in certificated form may transfer all or any of his shares by an instrument of transfer in any usual form or any other form approved by the board. Any written instrument of transfer shall be signed by or on behalf of the transferor and (in the case of a partly paid share) the transferee.

In the case of uncertificated shares, the directors may take such action as they consider appropriate to achieve a transfer. The Uncertificated Securities Regulations 2001 permit shares to be issued and held in uncertificated form and transferred by means of a computer based system.

The board may decline to register any transfer of any share:

• which is not a fully paid share;

• where the transfer is not lodged at our registered office or such other place as the directors have appointed;

• where the transfer is not accompanied by the share certificate to which it relates, or such other evidence as the board may reasonably require to show the transferor’s right to make the transfer, or evidence of the right of someone other than the transferor to make the transfer on the transferor’s behalf;

36

• where the transfer is in respect of more than one class of share; and

• where the number of joint holders to whom the share is to be transferred exceeds four.

If the board declines to register a transfer, it must return to the transferee the instrument of transfer together with notice of the refusal, unless the board suspects that the proposed transfer may be fraudulent.

Shareholder Meetings

Annual General Meetings

In accordance with the U.K. Companies Act 2006, we are required in each year to hold an annual general meeting in addition to any other general meetings in that year and to specify the meeting as such in the notice convening it. The annual general meeting shall be convened whenever and wherever the board sees fit, subject to the requirements of the U.K. Companies Act 2006, as described in “—Differences in Corporate Law—Annual general meeting” and “—Differences in Corporate Law—Notice of general meetings” in this prospectus.

Notice of General Meetings

The arrangements for the calling of general meetings are described in “—Differences in Corporate Law—Notice of general meetings” in this prospectus.

Quorum of General Meetings

No business shall be transacted at any general meeting unless a quorum is present. At least two shareholders present in person or by proxy and entitled to vote shall be a quorum for all purposes.

Class Meetings

The provisions in our articles of association relating to general meetings apply to every separate general meeting of the holders of a class of shares.

Directors

Number of Directors

We may not have less than two directors on the board of directors and not more than fifteen.

Appointment of Directors

Subject to the provisions of our articles of association, we may, by ordinary resolution of the shareholders or a decision of the directors, elect any person to be a director, either to fill a casual vacancy or as an addition to the existing board, provided the total number of directors does not exceed the maximum number fixed by or in accordance with the articles of association, provided, further, that a vacancy caused by the departure of a Principal Shareholder appointee may only be filled by the Principal Shareholder. However, any person that is not a director retiring from the existing board must be recommended by the board or the person must have confirmed in writing to the Company their willingness to be elected as a director.

Our articles of association provide for a staggered board consisting of three classes of directors. Directors of each class are chosen for three-year terms, with only one class of directors being elected

37

at each annual meeting of shareholders. At the first annual meeting of shareholders, the terms of the Class I directors (other than a Principal Shareholder appointee who is a Class I director) will expire and Class I directors (other than a Principal Shareholder appointee who is a Class I director) will be elected for a full term of three years. At the second annual meeting of shareholders, the terms of the Class II directors (other than a Principal Shareholder appointee who is a Class II director) will expire and Class II directors (other than a Principal Shareholder appointee who is a Class II director) will be elected for a full term of three years. At the third annual meeting of shareholders, the terms of the Class III directors (other than a Principal Shareholder appointee who is a Class III director) will expire and Class III directors (other than a Principal Shareholder appointee who is a Class III director) will be elected for a full term of three years. At each succeeding annual meeting, directors (other than Principal Shareholder appointees) will be elected for a full term of 3 years to succeed the directors of the class whose terms expire at such annual general meeting.

Directors’ Interests

If a situation arises in which a director has, or can have, a direct or indirect interest that conflicts, or possibly may conflict, with our interests (other than a situation that cannot reasonably be regarded as likely to give rise to a conflict of interest or a conflict of interest arising in relation to a transaction or arrangement with the Company), the board may authorize in accordance with the U.K. Companies Act 2006 the director’s interest and the continuing performance by the relevant director of his duties as a director on such terms as the board may determine.

A director shall not be accountable to us for any benefit which he derives from or in connection with a relationship involving a conflict of interest or possible conflict of interest which has been authorized by the directors or by the Company in a general meeting and any such transaction or arrangement shall not be liable to be avoided on the grounds of any such benefit.

Subject to the requirements under sections 175, 177 and 182 of the U.K. Companies Act 2006, a director shall declare the nature and extent of such conflicts.

A director may participate in the decision-making process and count in the quorum and vote on a proposed decision of the board which is concerned with such director’s interests (subject to any restrictions imposed by the other directors when providing such consent) if such director has declared the nature and extent of any interest of his and provided a majority of the other directors consent, or if one of the following situations applies:

• the director’s interest arises solely through an interest in shares, debentures or other securities of or otherwise in or through the Company;

• an ordinary resolution of the Company permits the director to count in the quorum and vote on the proposed decision;

• the conflict of interest arises from one of the following:

• the giving of a guarantee, security or indemnity in respect of money lent or obligations incurred by them or any other person at the request of or for the benefit of, the Company or any of its subsidiary undertakings;

• the giving of a guarantee, security or indemnity in respect of a debt or obligation of the Company or any of its subsidiary undertakings for which the director has assumed responsibility (in whole or part and whether alone or jointly with others) under a guarantee or indemnity or by the giving of security;

• a contract, arrangement, transaction or proposal concerning an offer of shares, debentures or other securities of the Company or any of its subsidiary undertakings for subscription or

38

purchase, in which offer they are or may be entitled to participate as a holder of securities or in the underwriting or sub-underwriting of which they are to participate;

• proposals concerning another company in which the director is interested directly or indirectly (whether as officer, shareholder or otherwise), if the director and any other persons connected with him do not to his knowledge hold an interest in shares representing 1% or more of the issued shares of any class of the equity share capital of that company (or of any third company through which his or their interest is derived) or of the voting rights available to shareholders of the relevant company;

• a contract, arrangement, transaction or proposal for the benefit of employees of the Company or of any of its subsidiary undertakings which does not award them any privilege or benefit not generally accorded to the employees to whom the arrangement relates; or

• a contract, arrangement, transaction or proposal concerning any insurance which the Company is empowered to purchase or maintain for, or for the benefit of, and directors of the Company or for persons who include directors of the Company.

A director shall not be counted in the quorum present at a meeting in relation to a resolution on which he is not entitled to vote.

If a question arises at a meeting of the board or of a committee of the board as to the right of a director to vote, the question may, before the conclusion of the meeting, be referred to the chair of the meeting and their ruling in relation to any director other than himself shall be final and conclusive, save where the nature of the interests of the direct have been fully disclosed.

Directors’ Fees and Remuneration

Each of the directors is entitled to remuneration as determined by the board for their service as directors and other services undertaken for the Company.

Each director may be paid his expenses in connection with such director’s attendance at meetings of the board or committees of the board or general meetings or separate meetings of the holders class of shares or of debentures, or otherwise in connection with the exercise of powers and the discharge of responsibilities in relation to the Company.

Indemnity

Every director, officer or former director or officer of our group may be indemnified against all costs, charges, losses, expenses and liabilities incurred by him in connection with any negligence, default, breach of duty, or breach of trust by him in relation to us or in connection with our activities as a trustee of an occupational pension scheme, in the actual or purported exercise of his powers or duties or otherwise as our officer, to the extent permitted under the U.K. Companies Act 2006.

Other U.K. Law Considerations

Mandatory Purchases and Acquisitions

Pursuant to Sections 979 to 991 of the U.K. Companies Act 2006, where a takeover offer has been made for us and the offeror has acquired or unconditionally contracted to acquire not less than 90% in value of the shares to which the offer relates and not less than 90% of the voting rights carried by those shares, the offeror may give notice to the holder of any shares to which the offer relates which the offeror has not acquired or unconditionally contracted to acquire that he wishes to acquire, and is

39

entitled to so acquire, those shares on the same terms as the general offer. The offeror would do so by sending a notice to the outstanding minority shareholders telling them that it will compulsorily acquire their shares. Such notice must be sent within three months of the last day on which the offer can be accepted in the prescribed manner. The squeeze-out of the minority shareholders can be completed at the end of six weeks from the date the notice has been given, subject to the minority shareholders failing to successfully lodge an application to the court to prevent such squeeze-out any time prior to the end of those six weeks following which the offeror can execute a transfer of the outstanding shares in its favor and pay the consideration to us, which would hold the consideration on trust for the outstanding minority shareholders. The consideration offered to the outstanding minority shareholders whose shares are compulsorily acquired under the U.K. Companies Act 2006 must, in general, be the same as the consideration that was available under the takeover offer.

Sell Out

The U.K. Companies Act 2006 also gives our minority shareholders a right to be bought out in certain circumstances by an offeror who has made a takeover offer for all of our shares. The holder of shares to which the offer relates, and who has not otherwise accepted the offer, may require the offeror to acquire his shares if, prior to the expiry of the acceptance period for such offer, (i) the offeror has acquired or unconditionally agreed to acquire not less than 90% in value of the voting shares, and (ii) not less than 90% of the voting rights carried by those shares. The offeror may impose a time limit on the rights of minority shareholders to be bought out that is not less than three months after the end of the acceptance period. If a shareholder exercises his rights to be bought out, the offeror is required to acquire those shares on the terms of this offer or on such other terms as may be agreed.

Disclosure of Interest in Shares

Pursuant to Part 22 of the U.K. Companies Act 2006, we are empowered to give notice in writing to any person whom we know or have reasonable cause to believe to be interested in our shares, or to have been so interested at any time during the three years immediately preceding the date on which the notice is issued requiring such persons, within a reasonable time to disclose to us particulars of that person’s interest and (so far as is within his knowledge) particulars of any other interest that subsists or subsisted in those shares.

Under our articles of association, if a person defaults in supplying us with the required particulars in relation to the ordinary shares in question, or default shares, within the prescribed period, the directors may by notice direct that:

• in respect of the default shares, the relevant shareholder shall not be entitled to attend or vote (either in person or by proxy) at a general meeting or at a separate meeting of the holders of that class of shares or on a poll;

• in respect of the default shares:

• no payment shall be made by way of dividend and no share shall be allotted pursuant to scrip dividend;

• no transfer of any default share shall be registered unless:

(A)    the shareholder is not himself in default as regards to supplying the information requested and the transfer when presented for registration is accompanied by a certificate by the shareholder in such form as the board may in its absolute discretion require to the effect that after due and careful enquiry the shareholder is satisfied that no person in default as regards supplying such information is interested in any of the shares the subject of the transfer; or

(B)    the transfer is an approved transfer.

Purchase of Own Shares

Under English law, a limited company may only purchase its own shares out of the distributable profits of the company or the proceeds of a fresh issue of shares made for the purpose of financing the purchase, provided that they are not restricted from doing so by their articles. A limited company may not purchase its own shares if, as a result of the purchase, there would no longer be any issued shares of the company other than redeemable shares or shares held as treasury shares. Shares must be fully paid in order to be repurchased.

We may purchase our own fully paid shares otherwise than on a recognized investment exchange pursuant to a purchase contract authorized by resolution of shareholders before the purchase takes place. Any authority will not be effective if any shareholder from whom we propose to purchase shares votes on the resolution and the resolution would not have been passed if he had not done so. The resolution authorizing the purchase must specify a date, not being later than five years after the passing of the resolution, on which the authority to purchase is to expire.

Distributions and Dividends

Under the U.K. Companies Act 2006, before a company can lawfully make a distribution or dividend, it must ensure that it has sufficient distributable reserves (on a non-consolidated basis). The basic rule is that a company’s profits available for the purpose of making a distribution are its accumulated, realized profits, so far as not previously utilized by distribution or capitalization, less its accumulated, realized losses, so far as not previously written off in a reduction or reorganization of capital duly made. The requirement to have sufficient distributable reserves before a distribution or dividend can be paid applies to us and to each of our subsidiaries that has been incorporated under English law.

It is not sufficient that we, as a public company, have made a distributable profit for the purpose of making a distribution. An additional capital maintenance requirement is imposed on us to ensure that the net worth of the company is at least equal to the amount of its capital. A public company can only make a distribution:

• if, at the time that the distribution is made, the amount of its net assets (that is, the total excess of assets over liabilities) is not less than the total of its called up share capital and distributable reserves; and

• if, and to the extent that, the distribution itself, at the time that it is made, does not reduce the amount of the net assets to less than that total.

On May 5, 2021, we capitalized $2,643,998,527 standing to the credit of our merger reserve by paying up the nominal value in full of 264,399,852,700 deferred shares (the “Capital Reduction Shares”), each with a nominal value of $0.01, and an aggregate nominal value of $2,643,998,527. On May 7, 2021, we applied to the High Court of Justice in England and Wales (the “Court”) seeking the Court’s approval for (i) the cancellation of the Capital Reduction Shares and the reduction of our share capital accordingly and (ii) the cancellation of $1,417,569,531, being the amount standing to credit in our share premium account as of June 14, 2021 (the “Capital Reduction”). The Capital Reduction was approved by the Court and took legal effect on June 15, 2021. The purpose of the Capital Reduction was to create distributable reserves in the amount of $4,061,568,058 in our books of account.

Compromises and Arrangements

Where we and our creditors or shareholders or a class of either of them propose a compromise or arrangement between us and our creditors or our shareholders or a class of either of them (as

41

applicable), the High Court of Justice in England and Wales may order a meeting of the creditors or class of creditors or of our shareholders or class of shareholders (as applicable) to be called in such a manner as the court directs. Any compromise or arrangement approved by a majority in number present and voting at the meeting representing 75% or more in value of the creditors or 75% or more of the voting rights of shareholders or class of either of them (as applicable) if sanctioned by the court, is binding upon us and all the creditors, shareholders or members of the specific class of either of them (as applicable).

Whether the capital of the Company is to be treated as being divided into a single or multiple class(es) of shares is a matter to be determined by the court. The court may in its discretion treat a single class of shares as multiple classes, or multiple classes of shares as a single class, for the purposes of the shareholder approval referred to above taking into account all relevant circumstances, which may include circumstances other than the rights attaching to the shares themselves.

City Code on Takeovers and Mergers

The U.K. City Code on Takeovers and Mergers (the “Takeover Code”) applies, among other things, to an offer for a public company whose registered office is in the United Kingdom and which is considered by the Panel on Takeovers and Mergers (the “Takeover Panel”), to have its place of central management and control in the United Kingdom, the Channel Islands or the Isle of Man (in each case, a “Code Company”). This is known as the “residency test.” Under the Takeover Code, the Takeover Panel will determine whether we have our place of central management and control in the United Kingdom, the Channel Islands or the Isle of Man by looking at various factors, including the structure of our Board, the functions of the directors, and where they are resident.

If at the time of a takeover offer, the Takeover Panel determines that the residency test is satisfied and we have our place of central management and control in the United Kingdom, we would be subject to several rules and restrictions, including but not limited to the following: (i) our ability to enter into deal protection arrangements with a bidder would be extremely limited; (ii) we might not, without the approval of our shareholders, be able to perform certain actions that could have the effect of frustrating an offer, such as issuing shares or carrying out acquisitions or disposals; and (iii) we would be obliged to provide equality of information to all bona fide competing bidders. The Takeover Code also contains certain rules in respect of mandatory offers for Code Companies. Under Rule 9 of the Takeover Code, if a person:

• acquires an interest in shares of a Code Company that, when taken together with shares in which persons acting in concert with such person are interested, carry 30% or more of the voting rights of the Code Company; or

• who, together with persons acting in concert with such person, is interested in shares that in the aggregate carry not less than 30% and not more than 50% of the voting rights in the Code Company, acquires additional interests in shares that increase the percentage of shares carrying voting rights in which that person is interested, the acquirer, and, depending on the circumstances, its concert parties, would be required (except with the consent of the Takeover Panel) to make a cash offer (or provide a cash alternative) for the Code Company’s outstanding shares at a price not less than the highest price paid for any interests in the shares by the acquirer or its concert parties during the previous 12 months.

A majority of our Board currently resides outside of the United Kingdom, the Channel Islands and the Isle of Man. Based upon our current and intended plans for our directors and management, for the purposes of the Takeover Code, we anticipate that the residency test will not be met and that we will be considered to have our place of central management and control outside the United Kingdom, the Channel Islands or the Isle of Man. Therefore, the Takeover Code should not apply to us. It is possible

42

that in the future changes in the Board’s composition, changes in the Takeover Panel’s interpretation of the Takeover Code, or other events may cause the Takeover Code to apply to us.

Exchange Controls

There are no governmental laws, decrees, regulations or other legislation in the United Kingdom that may affect the import or export of capital, including the availability of cash and cash equivalents for use by us, or that may affect the remittance of dividends, interest, or other payments by us to non-resident holders of our ordinary shares, other than withholding tax requirements. There is no limitation imposed by English law or in our articles of association on the right of non-residents to hold or vote shares.

Differences in Corporate Law

The applicable provisions of the U.K. Companies Act 2006 differ from laws applicable to U.S. corporations and their shareholders. Set forth below is a summary of certain differences between the provisions of the U.K. Companies Act 2006 applicable to us and the General Corporation Law of the State of Delaware relating to shareholders’ rights and protections.

	England and Wales	Delaware
Number of directors	Under the U.K. Companies Act 2006, a public limited company must have at least two directors and the number of directors may be fixed by or in the manner provided in a company’s articles of association.	Under Delaware law, a corporation must have at least one director and the number of directors shall be fixed by or in the manner provided in the bylaws.
Removal of directors	Under the U.K. Companies Act 2006, shareholders may remove a director without cause by an ordinary resolution (which is passed by a simple majority of those voting in person or by proxy at a general meeting) irrespective of any provisions of any service contract the director has with the company, provided 28 clear days’ notice of the resolution has been given to the company and its shareholders. On receipt of notice of an intended resolution to remove a director, the company must forthwith send a copy of the notice to the director concerned. Certain other procedural requirements under the U.K. Companies Act 2006 must also be followed such as allowing the director to make representations against his or her removal either at the meeting or in writing.	Under Delaware law, any director or the entire board of directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors, except (a) unless the certificate of incorporation provides otherwise, in the case of a corporation whose board of directors is classified, shareholders may effect such removal only for cause, or (b) in the case of a corporation having cumulative voting, if less than the entire board of directors is to be removed, no director may be removed without cause if the votes cast against his removal would be sufficient to elect him if then cumulatively voted at an election of the entire board of directors, or, if there are classes of directors, at an election of the class of directors of which he is a part.

43

	England and Wales	Delaware
Vacancies on the board of directors	Under English law, the procedure by which directors, other than a company’s initial directors, are appointed is generally set out in a company’s articles of association, provided that where two or more persons are appointed as directors of a public limited company by resolution of the shareholders, resolutions appointing each director must be voted on individually.	Under Delaware law, vacancies and newly created directorships may be filled by a majority of the directors then in office (even though less than a quorum) or by a sole remaining director unless (a) otherwise provided in the certificate of incorporation or by-laws of the corporation or (b) the certificate of incorporation directs that a particular class of stock is to elect such director, in which case a majority of the other directors elected by such class, or a sole remaining director elected by such class, will fill such vacancy.
Annual general meeting	Under the U.K. Companies Act 2006, a public limited company must hold an annual general meeting in each six-month period following the company’s annual accounting reference date.	Under Delaware law, the annual meeting of shareholders shall be held at such place, on such date and at such time as may be designated from time to time by the board of directors or as provided in the certificate of incorporation or by the bylaws.
General meeting	Under the U.K. Companies Act 2006, a general meeting of the shareholders of a public limited company may be called by the directors. Shareholders holding at least 5% of the paid-up capital of the company carrying voting rights at general meetings (excluding any paid up capital held as treasury shares) can require the directors to call a general meeting and, if the directors fail to do so within a certain period, may themselves convene a general meeting.	Under Delaware law, special meetings of the shareholders may be called by the board of directors or by such person or persons as may be authorized by the certificate of incorporation or by the bylaws.
Notice of general meetings	Under the U.K. Companies Act 2006, 21 clear days’ notice must be given for an annual general meeting and any resolutions to be proposed at the meeting. Subject to a company’s articles of association providing for a longer period, at least 14 clear days’	Under Delaware law, unless otherwise provided in the certificate of incorporation or bylaws, written notice of any meeting of the shareholders must be given to each shareholder entitled to vote at the meeting not less than ten nor more than 60 days before the date of the meeting and shall specify the

44

	England and Wales	Delaware
	notice is required for any other general meeting. In addition, certain matters, such as the removal of directors or auditors, require special notice, which is 28 clear days’ notice. The shareholders of a company may in all cases consent to a shorter notice period, the proportion of shareholders’ consent required being 100% of those entitled to attend and vote in the case of an annual general meeting and, in the case of any other general meeting, a majority in number of the members having a right to attend and vote at the meeting, being a majority who together hold not less than 95% in nominal value of the shares giving a right to attend and vote at the meeting.	place, date, hour, and purpose or purposes of the meeting.
Pre-emptive rights	Under the U.K. Companies Act 2006, “equity securities”, being (i) shares in the company other than shares that, with respect to dividends and capital, carry a right to participate only up to a specified amount in a distribution (“ordinary shares”) or (ii) rights to subscribe for, or to convert securities into, ordinary shares, proposed to be allotted for cash must be offered first to the existing equity shareholders in the company in proportion to the respective nominal value of their holdings, unless an exception applies or a special resolution to the contrary has been passed by shareholders in a general meeting or the articles of association provide otherwise in each case in accordance with the provisions of the U.K. Companies Act 2006.	Under Delaware law, shareholders have no preemptive rights to subscribe to additional issues of stock or to any security convertible into such stock unless, and except to the extent that, such rights are expressly provided for in the certificate of incorporation.
Authority to allot	Under the U.K. Companies Act 2006, the directors of a company must not allot shares or grant of rights to subscribe for or to convert any security into shares unless an	Under Delaware law, if the corporation’s charter or certificate of incorporation so provides, the board of directors has the power to authorize the issuance of stock. It

	exception applies or an ordinary resolution to the contrary has been passed by shareholders in a general meeting or the articles of association provide otherwise in each case in accordance with the provisions of the U.K. Companies Act 2006.	may authorize capital stock to be issued for consideration consisting of cash, any tangible or intangible property or any benefit to the corporation or any combination thereof. It may determine the amount of such consideration by approving a formula. In the absence of actual fraud in the transaction, the judgment of the directors as to the value of such consideration is conclusive.
Liability of directors and officers	Under the U.K. Companies Act 2006, any provision, whether contained in a company’s articles of association or any contract or otherwise, that purports to exempt a director of a company, to any extent, from any liability that would otherwise attach to him in connection with any negligence, default, breach of duty or breach of trust in relation to the company is void. Any provision by which a company directly or indirectly provides an indemnity, to any extent, for a director of the company or of an associated company against any liability attaching to him in connection with any negligence, default, breach of duty or breach of trust in relation to the company of which he is a director is also void except as permitted by the U.K. Companies Act 2006, which provides exceptions for the company to (a) purchase and maintain insurance against such liability; (b) provide a “qualifying third party indemnity” (being an indemnity against liability incurred by the director to a person other than the company or an associated company or criminal proceedings in which he is convicted); and (c) provide a “qualifying pension scheme indemnity” (being an indemnity against liability incurred in connection with the company’s	Under Delaware law, a corporation’s certificate of incorporation may include a provision eliminating or limiting the personal liability of a director to the corporation and its shareholders for damages arising from a breach of fiduciary duty as a director. However, no provision can limit the liability of a director for: •  any breach of the director’s duty of loyalty to the corporation or its shareholders; •  acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law; •  intentional or negligent payment of unlawful dividends or stock purchases or redemptions; or •  any transaction from which the director derives an improper personal benefit.

	activities as trustee of an occupational pension plan).
Voting rights	Under English law, unless a poll is demanded by the shareholders of a company or is required by the chairman of the meeting or the company’s articles of association, shareholders shall vote on all resolutions on a show of hands. Under the U.K. Companies Act 2006, a poll may be demanded by (a) not fewer than five shareholders having the right to vote on the resolution; (b) any shareholder(s) representing not less than 10% of the total voting rights of all the shareholders having the right to vote on the resolution (excluding any voting rights attaching to treasury shares); or (c) any shareholder(s) holding shares in the company conferring a right to vote on the resolution (excluding any voting rights attaching to treasury shares) being shares on which an aggregate sum has been paid up equal to not less than 10% of the total sum paid up on all the shares conferring that right. A company’s articles of association may provide more extensive rights for shareholders to call a poll. Under English law, an ordinary resolution is passed on a show of hands if it is approved by a simple majority (more than 50%) of the votes cast by shareholders present (in person or by proxy) and entitled to vote. If a poll is demanded, an ordinary resolution is passed if it is approved by holders representing a simple majority of the total voting rights of shareholders present, in person or by proxy, who, being entitled to vote, vote on the resolution. Special resolutions require the affirmative vote of not less than 75% of the votes cast by shareholders present (in person or by proxy) at the meeting. If a poll is demanded, a special resolution is passed if it is approved by holders	Delaware law provides that, unless otherwise provided in the certificate of incorporation, each shareholder is entitled to one vote for each share of capital stock held by such shareholder. Generally, under Delaware law, unless the certificate of incorporation provides for the vote of a larger portion of the stock, completion of a merger, consolidation, sale, lease or exchange of all or substantially all of a corporation’s assets or dissolution requires: •  the approval of the board of directors; and •  approval by the vote of the holders of a majority of the outstanding stock or, if the certificate of incorporation provides for more or less than one vote per ordinary share, a majority of the votes of the outstanding stock of a corporation entitled to vote on the matter.

47

	England and Wales	Delaware
	representing not less than 75% of the total voting rights of shareholders present (in person or by proxy) who (being entitled to vote) vote on the resolutions. The U.K. Companies Act 2006 provides for schemes of arrangement, which are arrangements or compromises between a company and any class of shareholders or creditors and used in certain types of reconstructions, amalgamations, capital reorganizations, or takeovers. These arrangements require: •  the approval at a shareholders’ or creditors’ meeting convened by order of the court, of a majority in number of shareholders or creditors representing 75% in value of the capital held by, or debt owed to, the class of shareholders or creditors, or class thereof present and voting, either in person or by proxy; and •  the approval of the court.
Standard of conduct for directors	Under English law, a director owes various statutory and fiduciary duties to the company, including: •  to act in the way he considers, in good faith, would be most likely to promote the success of the company for the benefit of its members as a whole; •  to avoid a situation in which he has, or can have, a direct or indirect interest that conflicts, or possibly conflicts, with the interests of the company; •  to act in accordance with the company’s constitution and only exercise his powers for the purposes for which they are conferred;	Delaware law does not contain specific provisions setting forth the standard of conduct of a director. The scope of the fiduciary duties of directors is generally determined by the courts of the State of Delaware. In general, directors have a duty to act without self-interest, on a well-informed basis and in a manner they reasonably believe to be in the best interest of the shareholders. Directors of a Delaware corporation owe fiduciary duties of care and loyalty to the corporation and to its shareholders. The duty of care generally requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar

48

	England and Wales	Delaware
	•  to exercise independent judgment; •  to exercise reasonable care, skill, and diligence; •  not to accept benefits from a third party conferred by reason of his being a director or doing, or not doing, anything as a director; and •  a duty to declare any interest that he has, whether directly or indirectly, in a proposed or existing transaction or arrangement with the company.	circumstances. Under this duty, a director must inform himself of all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he reasonably believes to be in the best interests of the corporation. He must not use his corporate position for personal gain or advantage. In general, but subject to certain exceptions, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Delaware courts have also imposed a heightened standard of conduct upon directors of a Delaware corporation who take any action designed to defeat a threatened change in control of the corporation. In addition, under Delaware law, when the board of directors of a Delaware corporation approves the sale or break-up of a corporation, the board of directors may, in certain circumstances, have a duty to obtain the highest value reasonably available to the shareholders.
Shareholder suits	Under English law, generally, the company, rather than its shareholders, is the proper claimant in an action in respect of a wrong done to the company or where there is an irregularity in the company’s internal management. Notwithstanding this general position, the U.K. Companies Act 2006 provides that (i) a court may allow a shareholder to bring a derivative claim (that is, an action in respect of and on behalf of the	Under Delaware law, a shareholder may initiate a derivative action to enforce a right of a corporation if the corporation fails to enforce the right itself. The complaint must: •  state that the plaintiff was a shareholder at the time of the transaction of which the plaintiff complains or that the plaintiffs shares thereafter devolved on the plaintiff by operation of law; and

company) in respect of a cause of action arising from a director’s negligence, default, breach of duty or breach of trust and (ii) a shareholder may bring a claim for a court order where the company’s affairs have been or are being conducted in a manner that is unfairly prejudicial to some of its shareholders.

•  allege with particularity the efforts made by the plaintiff to obtain the action the plaintiff desires from the directors and the reasons for the plaintiff’s failure to obtain the action; or •  state the reasons for not making the effort. Additionally, the plaintiff must remain a shareholder through the duration of the derivative suit. The action will not be dismissed or compromised without the approval of the Delaware Court of Chancery.

SHARES ELIGIBLE FOR FUTURE SALE

General

We cannot predict what effect, if any, market sales of ordinary shares or the availability of ordinary shares for sale will have on the market price of our ordinary shares prevailing from time to time. Nevertheless, sales of substantial amounts of ordinary shares, including shares issued upon the exercise of outstanding options, in the public market, or the perception that such sales could occur, could materially and adversely affect the market price of our ordinary shares and could impair our future ability to raise capital through the sale of our equity or equity-related securities at a time and price that we deem appropriate. See “Risk Factors—Risks Related to this Offering and Ownership of Our Ordinary Shares—Future sales, or the perception of future sales, by us or our existing shareholders in the public market following this offering could cause the market price for our ordinary shares to decline.”

As of July 4, 2021, we had 234,921,002 ordinary shares outstanding. All shares sold in this offering will be freely tradable without registration under the Securities Act and without restriction, except for shares held by our “affiliates” (as defined under Rule 144). The ordinary shares held by the Principal Shareholder and certain of our directors, officers, employees and other shareholders after this offering will be “restricted” securities under the meaning of Rule 144 and may not be sold in the absence of registration under the Securities Act, unless an exemption from registration is available, including the exemptions pursuant to Rule 144 under the Securities Act.

Pursuant to Rule 144, the restricted shares held by our affiliates and other shareholders will be available for sale in the public market at various times after the date of this prospectus following the expiration of the applicable lock-up period.

In addition, as of July 4, 2021, a total of 7,864,810 our ordinary shares have been reserved for issuance under the 2021 Incentive Award Plan (subject to adjustments for stock splits, stock dividends and similar events). The number of shares initially available for issuance will be increased by an annual increase on the first fiscal day of each calendar year beginning in 2022 and ending in and including 2031, equal to the least of (A) 3% of the ordinary shares outstanding on the final day of the immediately preceding calendar year and (B) a smaller number of shares determined by our board of directors. No more than 79,670,000 ordinary shares may be issued under the 2021 Plan upon the exercise of incentive stock options. Shares issued under the 2021 Plan may be authorized but unissued shares, shares purchased on the open market or treasury shares. We intend to file one or more registration statements on Form S-8 under the Securities Act to register ordinary shares issued or reserved for issuance under the 2021 Incentive Award Plan. Any such Form S-8 registration statement will automatically become effective upon filing. Accordingly, shares registered under such registration statement will be available for sale in the open market, unless such ordinary shares are subject to vesting or other contractual restrictions or the lock-up restrictions described below.

Rule 144

In general, under Rule 144, as currently in effect, a person (or persons whose shares are deemed aggregated) who is not deemed to be or have been one of our affiliates for purposes of the Securities Act at any time during 90 days preceding a sale and who has beneficially owned the ordinary shares proposed to be sold for at least six months, including the holding period of any prior owner other than an affiliate, is entitled to sell such ordinary shares without registration, subject to compliance with the public information requirements of Rule 144. If such a person has beneficially owned the ordinary shares proposed to be sold for at least one year, including the holding period of a prior owner other

51

than an affiliate, then such person is entitled to sell such ordinary shares without complying with any of the requirements of Rule 144.

Under Rule 144, our affiliates or persons selling shares on behalf of our affiliates, who have met the six-month holding period for beneficial ownership of “restricted shares” of our ordinary shares, are entitled to sell within any three-month period, a number of shares that does not exceed the greater of:

• 1% of the number of our ordinary shares then outstanding, which will equal approximately 2,349,210 shares immediately after this offering; or

• the average reported weekly trading volume of our ordinary shares on Nasdaq during the four calendar weeks preceding the filing of a notice on Form 144 with respect to such sale.

Sales under Rule 144 by our affiliates or persons selling shares on behalf of our affiliates are also subject to certain manner of sale provisions and notice requirements and to the availability of current public information about us. The sale of these shares, or the perception that sales will be made, could adversely affect the price of our ordinary shares after this offering because a great supply of shares would be, or would be perceived to be, available for sale in the public market.

Rule 701

In general, under Rule 701 of the Securities Act as currently in effect, any of our employees, consultants or advisors who received shares from us in connection with a compensatory stock or option plan or other written agreement in a transaction in reliance on Rule 701 that was completed before the effective date of the registration statement on Form S-1 for our initial public offering are now eligible to resell such ordinary shares in reliance on Rule 144, but without compliance with certain restrictions, including the holding period, contained in Rule 144. Such sales may, however, remain subject to the restrictions related to the lock-up agreements discussed below.

Registration Rights

Our Principal Shareholder has certain registration rights with respect to our ordinary shares pursuant to the Principal Shareholders Agreement. See “Certain Relationships and Related Party Transactions—Shareholders agreements—Principal Shareholders Agreement” in Ortho’s 2020 Form 10-K which is incorporated by reference in this prospectus.

Lock-up Agreements

In connection with this offering, we, our directors and executive officers, and the selling shareholder have each agreed with the underwriters, subject to certain exceptions, not to dispose of or hedge any of our or their ordinary shares or securities convertible into or exchangeable for ordinary shares during the period from the date of this prospectus continuing through the date 90 days after the date of this prospectus, except with the prior written consent of certain representatives of the underwriters.

Immediately following the consummation of this offering, equity holders subject to lock-up agreements will hold 122,176,446 of our ordinary shares (assuming no exercise of the underwriters’ option to purchase additional ordinary shares), representing approximately 51.6% of our then outstanding ordinary shares, or 118,876,446 of our ordinary shares if the underwriters exercise in full their option to purchase additional ordinary shares representing approximately 50.2% of our then outstanding ordinary shares.

52

We have agreed not to issue, sell or otherwise dispose of any our ordinary shares during the 90-day period following the date of this prospectus. We may, however, grant options to purchase ordinary shares, issue ordinary shares upon the exercise of outstanding options, issue ordinary shares in connection with certain acquisitions or business combinations or an employee stock purchase plan and in certain other circumstances.

MATERIAL TAX CONSIDERATIONS

Material U.S. Federal Income Tax Considerations

The following summary describes certain material U.S. federal income tax considerations generally applicable to U.S. Holders (as defined below), and solely to the extent described below under the heading “U.S. Foreign Account Tax Compliance Act,” to persons other than U.S. Holders, of an investment in the ordinary shares pursuant to this offering. This summary applies only to U.S. Holders that hold the ordinary shares as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”), that have acquired the ordinary shares in this offering and that have the U.S. dollar as their functional currency.

This discussion is based on the tax laws of the United States, including the Code, as in effect on the date hereof and on U.S. Treasury regulations as in effect or, in some cases, as proposed, on the date hereof, as well as judicial and administrative interpretations thereof available on or before such date. All of the foregoing authorities are subject to change or differing interpretations, which change or differing interpretation could apply retroactively and could affect the tax consequences described below. No ruling will be requested from the Internal Revenue Service (the “IRS”) regarding the tax consequences of this offering and there can be no assurance that the IRS will agree with the discussion set out below. This summary does not address any estate or gift tax consequences, the alternative minimum tax, the Medicare tax on net investment income or any state, local or non-U.S. tax consequences.

This summary also does not address the tax consequences that may be relevant to persons in special tax situations such as:

• banks;

• certain financial institutions;

• insurance companies;

• regulated investment companies;

• real estate investment trusts;

• individual retirement accounts and other tax-deferred accounts;

• broker-dealers;

• traders that elect to mark to market their securities;

• U.S. expatriates;

• tax-exempt entities;

• persons that own the ordinary shares as part of a “straddle,” “hedge,” “conversion transaction” or integrated transaction;

• persons that actually or constructively own 10% or more of the Company’s share capital (by vote or value);

• persons that are resident or ordinarily resident in or have a permanent establishment in a jurisdiction outside the United States;

• persons who acquired the ordinary shares pursuant to the exercise of any employee share option or otherwise as compensation;

• persons liable for alternative minimum tax of the Medicare contribution tax on net investment income;

54

• persons subject to special tax accounting rules as a result of any item of gross income with respect to the ordinary shares being taken into account in an applicable financial statement; or

• pass-through entities or arrangements, or persons holding ordinary shares through pass-through entities or arrangements.

THE SUMMARY OF U.S. FEDERAL INCOME TAX CONSIDERATIONS SET OUT BELOW IS FOR GENERAL INFORMATION ONLY. PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR TAX ADVISORS AS TO THE APPLICATION OF THE U.S. FEDERAL TAX RULES TO THEIR PARTICULAR CIRCUMSTANCES AS WELL AS THE STATE, LOCAL, NON-U.S. AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE ORDINARY SHARES.

As used herein, the term “U.S. Holder” means a beneficial owner of the ordinary shares that is, for U.S. federal income tax purposes:

• an individual who is a citizen or resident of the United States;

• a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof or the District of Columbia;

• an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

• a trust that (1) is subject to the primary supervision of a court within the United States and the control of one or more U.S. persons for all its substantial decisions or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

If an entity or other arrangement treated as a partnership for U.S. federal income tax purposes holds ordinary shares, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. Partnerships considering an investment in ordinary shares and partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences of owning and disposing of ordinary shares.

Taxation of Dividends and Other Distributions on the Ordinary Shares

Subject to the passive foreign investment company rules discussed below, the gross amount of any distributions made by the Company with respect to our ordinary shares (including the amount of non-U.S. taxes withheld therefrom, if any) generally will be includible in a U.S. Holder’s gross income as dividend income on the date of receipt, but only to the extent the distribution is paid out of the Company’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because the Company does not maintain calculations of its earnings and profits under U.S. federal income tax principles, a U.S. Holder should expect all cash distributions to be reported as dividends for U.S. federal income tax purposes. Such dividends will not be eligible for the dividends received deduction allowed to U.S. corporations with respect to dividends received from other U.S. corporations.

With respect to certain non-corporate U.S. Holders, including individual U.S. Holders, dividends may be taxed at the lower capital gain rates applicable to “qualified dividend income,” provided that (i) the ordinary shares are readily tradable on an established securities market in the United States, (ii) certain holding period and at-risk requirements are met and (iii) the Company is not a passive foreign investment company (as discussed below) with respect to the relevant U.S. Holder for either the taxable year in which the dividend was paid or the preceding taxable year. In this regard, the ordinary shares will generally be considered to be readily tradable on an established securities market in the United States if they are listed on Nasdaq.

55

Dividends on the ordinary shares generally will constitute foreign source income for foreign tax credit limitation purposes. Subject to certain complex conditions and limitations, foreign taxes withheld on any distributions on ordinary shares, if any, may be eligible for credit against a U.S. Holder’s federal income tax liability. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividends distributed by the Company with respect to ordinary shares will generally constitute “passive category income.” However, if the Company is a “United States-owned foreign corporation,” solely for foreign tax credit purposes, a portion of the dividends allocable the Company’s U.S.-source earnings and profits may be re-characterized as U.S. source. A “United States-owned foreign corporation” is any foreign corporation in which United States persons own, directly or indirectly, 50% or more (by vote or by value) of the stock. Under an exception, dividends will not be allocated to U.S.-source income if less than 10% of the earnings and profits of the United States-owned foreign corporations are attributable to sources within the United States. We cannot provide any assurances that we will not be characterized as a “United States-owned foreign corporation.” If we are a United States-owned foreign corporation, if 10% or more of our earnings and profits are attributable to sources within the United States, the portion of the dividends paid on the ordinary shares allocable to our United States source earnings and profits would be treated as U.S.-source, and a U.S. Holder would not be permitted to offset any foreign tax withheld as a credit against U.S. federal income tax imposed on that portion of the dividends. The rules relating to the determination of the U.S. foreign tax credit are complex. U.S. Holders should consult their tax advisors regarding the availability of a foreign tax credit in their particular circumstances and the possibility of claiming an itemized deduction (in lieu of the foreign tax credit) for any foreign taxes paid or withheld.

Taxation of Disposition of the Ordinary Shares

Subject to the passive foreign investment company rules discussed below, upon a sale or other taxable disposition of ordinary shares, a U.S. Holder will recognize capital gain or loss in an amount equal to the difference between the amount realized and the U.S. Holder’s adjusted tax basis in such ordinary shares. In general, a U.S. Holder’s adjusted tax basis in its ordinary shares will be equal to the cost of such ordinary shares to the U.S. Holder. Any such gain or loss generally will generally be treated as long-term capital gain or loss if the U.S. Holder’s holding period in the ordinary shares exceeds one year. Non-corporate U.S. Holders (including individuals) generally will be subject to U.S. federal income tax on long-term capital gain at preferential rates. The deductibility of capital losses is subject to significant limitations. Gain or loss, if any, recognized by a U.S. Holder on the sale or other disposition of ordinary shares generally will be treated as U.S. source gain or loss for U.S. foreign tax credit limitation purposes.

Passive Foreign Investment Company Rules

The Company will be classified as a passive foreign investment company (a “PFIC”) for any taxable year if either: (a) at least 75% of its gross income is “passive income” for purposes of the PFIC rules or (b) at least 50% of the value of its assets (determined on the basis of a quarterly average) is attributable to assets that produce or are held for the production of passive income. For this purpose, the Company will be treated as owning its proportionate share of the assets and earning its proportionate share of the income of any other corporation in which it owns, directly or indirectly, 25% or more (by value) of the stock.

Under the PFIC rules, if the Company were considered a PFIC at any time that a U.S. Holder holds ordinary shares, the Company would continue to be treated as a PFIC with respect to such investment unless (i) the Company ceases to be a PFIC and (ii) the U.S. Holder has made a “deemed sale” election under the PFIC rules.

56

Based on the recent, current and anticipated composition of the income, assets and operations of the Company and its subsidiaries, the Company does not expect to be treated as a PFIC for the taxable year ended January 3, 2021 or the current taxable year. This is a factual determination, however, that depends on, among other things, the composition of the income and assets, and the market value of the shares and assets, of the Company and its subsidiaries from time to time, and thus the determination can be made only annually after the close of each taxable year. Therefore there can be no assurances that the Company will not be classified as a PFIC for the taxable year ended January 3, 2021, the current taxable year or for any future taxable year.

If the Company is considered a PFIC at any time that a U.S. Holder holds ordinary shares, any gain recognized by the U.S. Holder on a sale or other disposition of the ordinary shares, as well as the amount of any “excess distribution” (defined below) received by the U.S. Holder, would be allocated ratably over the U.S. Holder’s holding period for the ordinary shares. The amounts allocated to the taxable year of the sale or other disposition (or the taxable year of receipt, in the case of an excess distribution) and to any year before the Company became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge would be imposed. For purposes of these rules, an excess distribution is the amount by which any distribution received by a U.S. Holder on ordinary shares exceeds 125% of the average of the annual distributions on the ordinary shares received during the preceding three years or the U.S. Holder’s holding period, whichever is shorter. Certain elections may be available that would result in alternative treatments (such as qualified electing fund treatment or mark-to-market treatment) of our ordinary shares if we are considered a PFIC. We do not intend to provide the information necessary for U.S. Holders of our ordinary shares to make qualified electing fund elections, which, if available, would result in tax treatment different from the general tax treatment for an investment in a PFIC described above. If we are treated as a PFIC with respect to a U.S. Holder for any taxable year, the U.S. Holder will be deemed to own shares in any of our subsidiaries that are also PFICs. However, an election for mark-to-market treatment would likely not be available with respect to any such subsidiaries.

If the Company is considered a PFIC, a U.S. Holder would also be subject to annual information reporting requirements. Failure to comply with such information reporting requirements may result in significant penalties and may suspend the running of the statute of limitations. U.S. Holders should consult their tax advisors about the potential application of the PFIC rules to an investment in ordinary shares.

Information Reporting and Backup Withholding

Dividend payments with respect to ordinary shares and proceeds from the sale, exchange or redemption of ordinary shares may be subject to information reporting to the IRS and U.S. backup withholding. A U.S. Holder may be eligible for an exemption from backup withholding if the U.S. Holder furnishes a correct taxpayer identification number and makes any other required certification or is otherwise exempt from backup withholding. U.S. Holders who are required to establish their exempt status may be required to provide such certification on IRS Form W-9. U.S. Holders should consult their tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a U.S. Holder’s U.S. federal income tax liability, and such U.S. Holder may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing an appropriate claim for refund with the IRS and furnishing any required information.

57

Information with Respect to Foreign Financial Assets

Certain U.S. Holders who are individuals (and certain entities) that hold an interest in “specified foreign financial assets” (which may include the ordinary shares) are required to report information relating to such assets, subject to certain exceptions (including an exception for ordinary shares held in accounts maintained by certain financial institutions). U.S. Holders should consult their tax advisors regarding the effect, if any, of this requirement on their ownership and disposition of the ordinary shares.

U.S. Foreign Account Tax Compliance Act (FATCA)

Certain provisions of the Code and the Treasury regulations (commonly collectively referred to as “FATCA”) generally impose withholding at a rate of 30% on “foreign passthru payments” made by a “foreign financial institution” (as defined in the Code) (an “FFI”). If the Company were to be treated as an FFI, such withholding may be imposed on such payments to any other FFI (including an intermediary through which an investor may hold the ordinary shares) that is not a “participating FFI” (as defined under FATCA) or any other investor who does not provide information sufficient to establish that the investor is not subject to withholding under FATCA, unless such other FFI or investor is otherwise exempt from FATCA. In addition, under those circumstances, the Company may be required to report certain information regarding investors to the relevant tax authorities, which information may be shared with taxing authorities in the United States. Under current guidance, the term “foreign passthru payment” is not defined. Consequently, it is not clear whether or to what extent payments on the ordinary shares would be considered foreign passthru payments. Withholding on foreign passthru payments would not be required with respect to payments made before the date that is two years after the date of publication in the Federal Register of final regulations defining the term “foreign passthru payment.” Prospective investors should consult their tax advisors regarding the potential impact of FATCA, any applicable inter-governmental agreement relating to FATCA, and any non-U.S. legislation implementing FATCA on the investment in the ordinary shares.

THE DISCUSSION ABOVE IS A GENERAL SUMMARY. IT DOES NOT COVER ALL TAX MATTERS THAT MAY BE IMPORTANT TO YOU. EACH PROSPECTIVE PURCHASER SHOULD CONSULT ITS OWN TAX ADVISOR ABOUT THE TAX CONSEQUENCES OF AN INVESTMENT IN ORDINARY SHARES UNDER THE INVESTOR’S OWN CIRCUMSTANCES.

Material U.K. Tax Considerations

The following statements are of a general nature and do not purport to be a complete analysis of all potential United Kingdom tax consequences of acquiring, holding and disposing of the ordinary shares pursuant to this offering. They are based on current United Kingdom tax law and on the current published practice of HMRC (which may not be binding on HMRC), as of the date of this prospectus, all of which are subject to change, possibly with retrospective effect. They are intended to address only certain United Kingdom tax consequences for holders who are tax resident in (and only in) the United Kingdom, and in the case of individuals, domiciled in (and only in) the United Kingdom (except where expressly stated otherwise) who are the absolute beneficial owners of the ordinary shares and any dividends paid on them and who hold the ordinary shares as investments (other than in an individual savings account or a self-invested personal pension). They do not address the United Kingdom tax consequences which may be relevant to certain classes of holders such as traders, brokers, dealers, banks, financial institutions, insurance companies, investment companies, collective investment schemes, tax-exempt organisations, trustees, persons connected with the Company, persons holding its ordinary shares as part of hedging or conversion transactions, holders who have (or are deemed to have) acquired their ordinary shares by virtue of an office or employment, and holders who are or have been officers or employees of the Company. The statements do not apply to any holder who either

58

directly or indirectly holds or controls 10% or more of the Company’s share capital (or class thereof), voting power or profits.

The following is intended only as a general guide and is not intended to be, nor should it be considered to be, legal or tax advice to any particular prospective subscriber for, or purchaser of, the ordinary shares. Accordingly, prospective subscribers for, or purchasers of, the ordinary shares who are in any doubt as to their tax position regarding the acquisition, ownership or disposition of the ordinary or who are subject to tax in a jurisdiction other than the United Kingdom should consult their own tax advisers.

(1) Taxation of Dividends

Withholding Tax

The Company will not be required to withhold United Kingdom tax at source when paying dividends. The amount of any liability to United Kingdom tax on dividends paid by the Company will depend on the individual circumstances of a holder.

Income Tax

An individual holder who is resident for tax purposes in the United Kingdom may, depending on his or her particular circumstances, be subject to United Kingdom tax on dividends received from the Company. An individual holder who is not resident for tax purposes in the United Kingdom should not be chargeable to United Kingdom income tax on dividends received from the Company unless he or she carries on (whether solely or in partnership) any trade, profession or vocation in the United Kingdom through a branch or agency to which the ordinary shares are attributable. There are certain exceptions for trading in the United Kingdom through independent agents, such as some brokers and investment managers.

All dividends received by a United Kingdom tax resident individual holder from the Company or from other sources will form part of the holder’s total income for income tax purposes and will constitute the top slice of that income. A nil rate of income tax will apply to the first £2,000 of taxable dividend income received by the holder in a tax year. Income within the nil rate band will be taken into account in determining whether income in excess of the nil rate band falls within the basic rate, higher rate or additional rate tax bands. Where the dividend income is above the £2,000 dividend allowance, the first £2,000 of the dividend income will be charged at the nil rate and any excess amount will be taxed at 7.5%. to the extent that the excess amount falls within the basic rate tax band, 32.5%. to the extent that the excess amount falls within the higher rate tax band and 38.1%. to the extent that the excess amount falls within the additional rate tax band.

Corporation Tax

Corporate holders which are resident for tax purposes in the United Kingdom should not be subject to United Kingdom corporation tax on any dividend received from the Company so long as the dividends qualify for exemption (as is likely) and certain conditions are met (including anti-avoidance conditions). If the conditions for exemption are not met or cease to be satisfied, or such a holder elects for an otherwise exempt dividend to be taxable, the holder will be subject to United Kingdom corporation tax on dividends received from the Company, at the rate of corporation tax applicable to that holder (the main rate of United Kingdom corporation tax is currently 19%).

Corporate holders who are not resident in the United Kingdom will not generally be subject to United Kingdom corporation tax on dividends unless they are carrying on a trade, profession or vocation in the United Kingdom through a permanent establishment in connection with which the ordinary shares are used, held, or acquired.

59

A holder who is resident outside the United Kingdom may be subject to non-United Kingdom taxation on dividend income under local law.

(2) Taxation of Capital Gains

United Kingdom Resident Holders

A disposal or deemed disposal of ordinary shares by an individual or corporate holder who is tax resident in the United Kingdom may, depending on the holder’s circumstances and subject to any available exemptions or reliefs, give rise to a chargeable gain or allowable loss for the purposes of United Kingdom taxation of chargeable gains.

Any chargeable gain (or allowable loss) will generally be calculated by reference to the consideration received for the disposal of the ordinary shares less the allowable cost to the holder of acquiring such ordinary shares.

The applicable tax rates for individual holders realising a gain on the disposal of ordinary shares is, broadly, 10% for basic rate taxpayers and 20% for higher and additional rate taxpayers. For corporate holders, corporation tax is generally charged on chargeable gains at the rate applicable to the relevant corporate holder.

Non-United Kingdom Holders

Holders who are not resident in the United Kingdom and, in the case of an individual holder, not temporarily non-resident, should not be liable for United Kingdom tax on capital gains realised on a sale or other disposal of ordinary shares unless (i) such ordinary shares are used, held or acquired for the purposes of a trade, profession or vocation carried on in the United Kingdom through a branch or agency or, in the case of a corporate holder, through a permanent establishment or (ii) where certain conditions are met, the Company derives 75% or more of its gross value from United Kingdom land. Holders who are not resident in the United Kingdom may be subject to non-United Kingdom taxation on any gain under local law.

Generally, an individual holder who has ceased to be resident in the United Kingdom for United Kingdom tax purposes for a period of five years or less and who disposes of ordinary shares during that period may be liable on their return to the United Kingdom to United Kingdom taxation on any capital gain realised (subject to any available exemption or relief).

(3) United Kingdom Stamp Duty (“Stamp Duty”) and United Kingdom Stamp Duty Reserve Tax (“SDRT”)

The statements in this paragraph 3 are intended as a general guide to the current position relating to stamp duty and SDRT and apply to any holder irrespective of their place of tax residence. Certain categories of person, including intermediaries, brokers, dealers and persons connected with depositary receipt arrangements and clearance services, may not be liable to stamp duty or SDRT or may be liable at a higher rate or may, although not primarily liable for the tax, be required to notify and account for it under the Stamp Duty Reserve Tax Regulations 1986.

Transfers of ordinary shares within a clearance service or depositary receipt system should not give rise to a liability to stamp duty or SDRT, provided that no instrument of transfer is entered into and that no election that applies to the ordinary shares is, or has been, made by the clearance service under Section 97A of the United Kingdom Finance Act 1986.

60

Transfers of ordinary shares within a clearance service where an election has been made by the clearance service under Section 97A of the Finance Act 1986 will generally be subject to SDRT (rather than stamp duty) at the rate of 0.5% of the amount or value of the consideration.

Transfers of ordinary shares that are held in certificated form will generally be subject to stamp duty at the rate of 0.5% of the consideration given (rounded up to the nearest £5). An exemption from stamp duty is available for a written instrument transferring an interest in ordinary shares where the amount or value of the consideration is £1,000 or less, and it is certified on the instrument that the transaction effected by the instrument does not form part of a larger transaction or series of transactions for which the aggregate consideration exceeds £1,000. SDRT may be payable on an agreement to transfer such ordinary shares, generally at the rate of 0.5% of the consideration given in money or money’s worth under the agreement to transfer the ordinary shares. This charge to SDRT would be discharged if an instrument of transfer is executed pursuant to the agreement which gave rise to SDRT and stamp duty is duly paid on the instrument transferring the ordinary shares within six years of the date on which the agreement was made or, if the agreement was conditional, the date on which the agreement became unconditional.

If ordinary shares (or interests therein) are subsequently transferred into a clearance service or depositary receipt system, stamp duty or SDRT will generally be payable at the rate of 1.5% of the amount or value of the consideration given or, in certain circumstances, the value of the shares (save to the extent that an election has been made under section 97A of the United Kingdom Finance Act 1986). This liability for stamp duty or SDRT will strictly be accountable by the clearance service or depositary receipt system, as the case may be, but will, in practice, generally be reimbursed by participants in the clearance service or depositary receipt system.

61

UNDERWRITING

The selling shareholder is offering the ordinary shares described in this prospectus through a number of underwriters. Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC are acting as representatives of the underwriters. The selling shareholder has entered into an underwriting agreement with the underwriters. Subject to the terms and conditions of the underwriting agreement, the selling shareholder has agreed to sell to the underwriters, and each underwriter has severally agreed to purchase from the selling shareholder, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus, the number of ordinary shares listed next to its name in the following table:

Name	Number of shares
Goldman Sachs & Co. LLC		4,840,000
J.P. Morgan Securities LLC		4,840,000
Morgan Stanley & Co. LLC		3,080,000
BofA Securities, Inc.		2,200,000
Barclays Capital Inc.		2,200,000
Citigroup Global Markets Inc.		770,000
Cowen and Company, LLC		770,000
Credit Suisse Securities (USA) LLC		770,000
UBS Securities LLC		770,000
Evercore Group L.L.C.		440,000
Piper Sandler & Co.		440,000
ING Financial Markets LLC		220,000
Macquarie Capital (USA) Inc.		220,000

Samuel A. Ramirez & Company, Inc.		55,000
Siebert Williams Shank & Co., LLC		55,000
Total		22,000,000

The underwriters are committed to purchase all the ordinary shares offered by the selling shareholder if they purchase any shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters propose to offer the ordinary shares directly to the public at the public offering price set forth on the cover page of this prospectus and to certain dealers at that price less a concession not in excess of $0.42 per share. After the initial offering to the public, the offering price, concession or any other term of the offering may be changed. The offering of the shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The underwriters have an option to buy up to 3,300,000 additional ordinary shares from the selling shareholder to cover sales of shares by the underwriters which exceed the number of shares specified in the table above. The underwriters have 30 days from the date of this prospectus to exercise this option to purchase additional shares. If any shares are purchased with this option to purchase additional shares, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional ordinary shares are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

62

The underwriting fee is equal to the public offering price per share of ordinary shares less the amount paid by the underwriters to the selling shareholder per share of ordinary shares. The underwriting fee is $0.70 per share. The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

	Without exercise of option to purchase additional shares		With full exercise of option to purchase additional shares exercise
Per share	$	0.70	$	0.70
Total	$	15,400,000	$	17,710,000

We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees and legal and accounting expenses, but excluding the underwriting discounts and commissions, will be approximately $1.1 million.

A prospectus in electronic format may be made available on the web sites maintained by one or more underwriters, or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters and selling group members that may make Internet distributions on the same basis as other allocations.

We have agreed that we will not (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, or file with the SEC a registration statement under the Securities Act relating to, any of our ordinary shares or securities convertible into or exercisable or exchangeable for any of our ordinary shares, or publicly disclose the intention to make any offer, sale, pledge, loan, disposition or filing, or (ii) enter into any swap or other arrangement that transfers all or a portion of the economic consequences associated with the ownership of any ordinary shares or any such other securities (regardless of whether any of these transactions are to be settled by the delivery of ordinary shares or such other securities, in cash or otherwise), in each case without the prior written consent of each of Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC for a period of 90 days after the date of this prospectus, subject to certain exceptions, including any shares to be sold in this offering.

The restrictions on our actions, as described above, do not apply to certain transactions, including (i) the issuance of ordinary shares or securities convertible into or exercisable for our ordinary shares pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options (including net exercise) or the settlement of RSUs (including net settlement), in each case outstanding on the date of the underwriting agreement and described in this prospectus; (ii) grants of stock options, stock awards, restricted stock, RSUs, or other equity awards and the issuance of our ordinary shares or securities convertible into or exercisable or exchangeable for our ordinary shares (whether upon the exercise of stock options or otherwise) to our employees, officers, directors, advisors, or consultants pursuant to the terms of an equity compensation plan in effect as of the closing of this offering and described in this prospectus; or (iii) our filing of any registration statement on Form S-8 relating to securities granted or to be granted pursuant to any plan described in this prospectus or any assumed benefit plan pursuant to an acquisition or similar strategic transaction.

Our directors and executive officers, and the selling shareholder (such persons, the “lock-up parties”) have entered into lock-up agreements with the underwriters prior to the commencement of

63

The selling shareholder has agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act.

Our ordinary shares are currently traded on Nasdaq under the symbol “OCDX”.

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling ordinary shares in the open market for the purpose of preventing or retarding a decline in the market price of the ordinary shares while this offering is in progress. These stabilizing transactions may include making short sales of ordinary shares, which involves the sale by the underwriters of a greater number of ordinary shares than they are required to purchase in this offering, and purchasing ordinary shares on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional shares referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the ordinary shares in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M of the Securities Act of 1933, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the ordinary shares, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase ordinary shares in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the ordinary shares or preventing or retarding a decline in the market price of the ordinary shares, and, as a result, the price of our ordinary shares may be higher than the price that otherwise might exist in the open market. The underwriters may carry out these transactions on Nasdaq, in the over-the-counter market or otherwise.

Neither we, the selling shareholder, nor the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our ordinary shares. In addition, neither we, the selling shareholder, nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

EXPERTS

The financial statements incorporated in this Prospectus by reference to the Annual Report on Form 10-K for the year ended January 3, 2021 have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP (“PwC”), an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

PwC completed an independence assessment to evaluate the services and relationships with the Company and its affiliates that may bear on PwC’s independence under the SEC and the PCAOB (United States) independence rules for an audit period commencing January 1, 2018, PwC informed us that certain of its member firms within PricewaterhouseCoopers International Limited, each member firm of which is a separate legal entity (“PwC member firm”), were engaged to perform non-audit services by and had relationships with entities that are under common control with Ortho Clinical Diagnostics Holdings plc. These non-audit services and relationships are not in accordance with the SEC and PCAOB auditor independence rules and are described below:

• From April 2019 to September 2020, a PwC member firm assisted in the preparation and submission of two statistical reports to a non-tax authority for an entity under common control with the Company. The fees for these services were approximately $1,600.

• From April 2018 to March 2019, a PwC covered person, who was not involved in the audit of the Company, held an impermissible financial interest in an affiliate of the Company.

• From August 2017 to January 2018, a PwC member firm had a business relationship with an entity under common control with the Company. The fees for these services were approximately $180,000.

• From November 2018 to February 2019, a PwC member firm provided an expert service to an entity under common control with the Company. The fees for these services were approximately $360,000 (fees for the services were not invoiced or collected).

• During March 2019, a PwC member firm held custody of documents and provided a registered office address for an entity under common control with the Company. There were no fees earned for this service.

PwC provided an overview of the facts and circumstances surrounding the services and relationships to our audit committee and management, including the entities involved, the nature of the relationships, where applicable, an approximation of the fees earned related to the services and relationships and other relevant factors. Considering the facts presented, our audit committee and PwC have concluded that the relationships would not impair PwC’s application of objective and impartial judgment on any matters encompassed within the audit engagement performed by PwC for our consolidated financial statements for each of the three years in the period ended January 3, 2021, and that no reasonable investor would conclude otherwise.

ENFORCEMENT OF JUDGMENTS

U.K. TopCo is a public limited company organized under the laws of England and Wales. As a result, the rights of holders of our ordinary shares is governed by U.K. law and our articles of association. The rights of shareholders under U.K. law may differ from the rights of shareholders of companies incorporated in other jurisdictions. A substantial amount of our assets are located outside the United States. As a result, it may be difficult for investors to enforce in the United States judgments obtained in U.S. courts against us based on the civil liability provisions of the U.S. securities laws. It is doubtful whether courts in England and Wales will enforce judgments obtained in other jurisdictions, including the United States, against us or our directors or officers under the securities laws of those jurisdictions or entertain actions in England and Wales against us or our directors or officers under the securities laws of other jurisdictions.

Our registered address in the United Kingdom is Felindre Meadows, Pencoed, Bridgend, Mid Glamorgan, Wales, CF35 5PZ.
