An outbreak of a strain of coronavirus that was discovered in China in late 2019 evolved into a global pandemic. To stem the spread of COVID-19 disease, in early 2020 nearly all major markets began to implement “stay-at-home” orders, business shutdowns, including offices of eye care professionals, and the deferral of non-urgent surgical procedures, leading to a global economic standstill. While these “stay-at-home” orders were largely lifted by mid-2020, some markets reintroduced targeted “stay-at-home” orders throughout the remainder of 2020.

The magnitude of the continued negative impact of the COVID-19 pandemic on our business, net sales, financial condition, liquidity and cash flows depends on future developments that are unpredictable and most of which are outside of our control, including the duration and scope of the pandemic, related governmental advisories and restrictions to contain COVID-19, how quickly economic conditions improve once the COVID-19 pandemic subsides, the development of therapeutic medicines and vaccines and whether there are subsequent outbreaks. We may be unable

Moreover, the effects of vaccine mandates are not yet known. A growing number of countries are making vaccination compulsory for workers. Further, certain customers have issued vaccine requirements with respect to prevent or mitigate anyour associates who visit their facilities. Our efforts to comply with these mandates, including requiring that some or all of the pandemic's near- or long-term adverse impacts, which could be material, such as:

Our industry is highly competitive and, in both our surgical and vision care businesses, we face a mixture of competitors and intense competition from competitors' products. While we currently enjoy leading positions within our industry, our success highly depends on our ability to maintain or build on those leading positions. To compete effectively, we must continue to create, invest in or acquire advanced technology, incorporate this technology into our proprietary products, obtain regulatory approvals in a timely manner where required and manufacture and successfully market our products. We may experience design, manufacturing, marketing or other difficulties that could delay or prevent our development, introduction or marketing of new products or new versions of our existing products. As a result of such difficulties and delays, our development expenses may increase and, as a consequence, our results of operations could suffer. Our failure to respond to competitive pressures in a timely manner could have a material adverse effect on our business, financial condition and results of operations.

For example, in our surgical business, we face a mixture of competitors ranging from large manufacturers with multiple business lines to small manufacturers that offer a limited selection of specialized products. Development by other companies of new or improved products, processes or technologies may make our products or proposed products less competitive or obsolete. We also face competition from providers of alternative medical therapies such as pharmaceutical companies that have the potential to disrupt core elements of our business.

Shifts in industry market share can occur in connection with product issues, physician advisories, safety alerts and publications about our products. In the current environment of managed care, consolidation among healthcare providers, increased competition and declining reimbursement rates, and absent innovation, we must increasingly compete on the basis of price.

In addition, our vision care business operates within a highly competitive environment. In contact lenses, we face intense competition from competitors' products and may face increasing competition as other new products enter the market, for example, with increased product entries from contact lens manufacturers in Asia. New market entrants and existing competitors are also challenging distribution models with innovation in non-traditional, disruptive models such as direct-to-consumer, Internet and other e-commerce sales opportunities, which could adversely impact the traditional eye care professional ("ECP") channel in which Alcon has a significant presence. Our major competitors in contact lenses offer competitive products and differentiated materials, plus a variety of other eye care products including ophthalmic pharmaceuticals, which may give them a competitive advantage in marketing their lenses. Our vision care business also competes with manufacturers of eyeglasses and providers of other forms of vision correction including ophthalmic surgery. The market for contact lenses is intensely competitive and is characterized by declining sales volumes for older and reusable product lines and growing demand for daily lenses and advanced materials lenses. As the market for contact lenses shifts toward daily lenses, we expect our sales in daily lenses to, at least in part, cannibalize sales of our reusable contact lenses and contact lens care offerings. Furthermore, our ocular health product category is also highly competitive. We cannot predict the timing or impact of the introduction of competitive products, including new market entries, "generic" versions of our approved products, or private label products that treat the same conditions as those of our products. In addition, the introduction of alternatives in medical devices and medical prescriptions could also alter the dry eye product market and impede our sales growth. Our ability to respond to these competitive pressures will depend on our ability to decrease our costs and maintain gross margins and operating results, and to introduce new products successfully and on a timely basis and to achieve manufacturing efficiencies and sufficient manufacturing capacity and capabilities for such products.

Finally, our financial performance also depends on our ability to successfully build and expand our markets. For example, while we currently expect our key markets to grow, particularly in multifocal contact lenses and AT-IOLs, the size of the markets in which we compete may not increase above existing levels, we may not be able to regain or gain market share, expand our market penetration or the size of the market for our products or compete effectively, and the number of procedures in which our products are used may not increase above existing levels. Decreases in market sizes or our market share and declines in average selling prices or procedural volumes could materially adversely affect our results of operations or financial condition. Furthermore, our failure to expand our markets beyond existing levels could impact our ability to grow in line with or above current industry standards.

Our ability to continue to maintain and grow our business, to replace sales lost due to competition and to bring to market products that take advantage of new and potentially disruptive technologies depends heavily on the success of our research and development activities. Our success relies on our ability to identify and successfully develop cost-effective new products that address unmet medical and consumer needs. To accomplish this, we commit substantial financial, human and capital resources to product research and development, both through our internal dedicated resources and

new products that will enable us to replace sales lost to our competitors or increase revenue to grow our business. We may not be able to successfully identify and obtain value from our external business development and strategic collaborative efforts. In addition, our new products may cannibalize a portion of the revenues we derive from existing products, therefore driving replacement revenue instead of incremental revenue.

Further, even if we are able to secure regulatory approval and achieve initial commercial success of our products, our products may abruptly cease to be commercially viable due to the discovery of adverse health effects. See "—We may implement product recalls or voluntary market withdrawals of our products" below.products."

If we are unable to maintain a cost-effective flow of successful new products sufficient to maintain and grow our business, cover any sales erosion due to competition and take advantage of market opportunities, this lack of innovation could have a material adverse effect on our business, financial condition or results of operations. For a description of the government approval processes which must be followed to market our products, see "—Regulatory clearance and approval processes for our products are expensive, time-consuming and uncertain, and the failure to obtain and maintain required regulatory clearances and approvals could prevent us from commercializing our products" below and "Item 4. Information on the Company—4.B. Business Overview—Government Regulation".

The prices, sales and demand for some of our products, in particular our surgical products, could be adversely affected by the increased emphasis managed care organizations and governments continue to place on the delivery of more cost-effective medical therapies.reducing health care costs. In addition, some third-party payors will not provide reimbursement for a new product until

OutsideIn the US as well as outside the US, governmental programs that typically reimburse at predetermined fixed rates may also decrease or otherwise limit amounts available through reimbursement. For example, in the EU, member states impose controls on whether products are reimbursable by national or regional health service providers and on the prices at which medical devices are reimbursed under state-run healthcare schemes. Some member states operate reference pricing systems in which they set national reimbursement prices by reference to those in other member states. Countries implementing a volume-based procurement process, such as the one being introducedinitiated in China in 2018, can lead to decreased prices. Other governmental funding restrictions, legislative proposals and interpretations of policy may negatively impact amounts available through reimbursement, including by restricting payment increases to hospitals and other providers through reimbursement systems, or by restricting whether reimbursement is available for our products at all.

We expect that additional health care reform measures will be adopted in the future in the countries in which we operate, including those initiatives affecting coverage and reimbursement for our products, any of which could limit the amounts that governments will pay for health care products and services, which could adversely affect the growth of the market for our products or the demand for our products, or result in additional pricing pressures. We cannot predict the effect such reforms or the prospect of their enactment may have on our business.

Increasingly, a significant portion of our global sales are made to a relatively small number of distributors, retail chains and other purchasing organizations, as consolidation and vertical integration have the potentialcontinue to disrupt existing channels. The recent trend, which is present globally including in the United States (our largest market), has been toward further consolidation among distributors, retailers and other eye care industry customers, such as eye care professionals, including through the acquisition of consolidated ophthalmology practices by private equity and other venture fund investors. As a result, our customers are gaining additional purchasing leverage, which increases the pricing pressures facing our businesses.

In our surgical business, healthcare providers, physician practices, hospitals and surgery centers around the world continue to consolidate in response to declining reimbursement rates and intensifying pressure to reduce healthcare delivery expenses. In vision care, private label growth and retailer-branded lenses may drive the commoditization of contact lenses and further boost the bargaining power of our distributors and retailers. This consolidation is increasing the ability of large groups to negotiate price, accelerating the transition of the decision maker from physicians to cost-focused professional buyers and potentially increasing price transparency or price referencing in instances of consolidation across borders.

Further, as our customers consolidate, if one or more of our major customers experienced financial difficulties, the effect on us would be substantially greater than in the past, and could include a substantial loss of sales and an inability to collect amounts owed to us.

We market our surgical products to healthcare providers, including ECPs, public and private hospitals, ambulatory surgical centers, eye clinics and ophthalmic surgeons' offices and group purchasing organizations and our vision care products to retailers and distributors. We have developed, and strive to maintain, strong relationships with members of each of these groups who assist in product research and development and advise us on how to satisfy the full range of consumer and surgeon needs. We rely on these groups to recommend our products to their patients and to other members of their organizations. Travel restrictions such as those due to the COVID-19 pandemic have increased the difficulty in maintaining these strong relationships.

Contact lens and lens care consumers have a tendency not to switch products regularly and are repeat consumers. As a result, the success of these products relies on an ECP’s initial recommendation of our products, which may be based on our ability to educate the ECP on our products. Even if we are successful at educating ECPs on our products, ECPs may continue to lose influence in the consumer's selection of contact lenses, which would cause our business to become more dependent upon the success of educating consumers directly. If we had to increase our direct-to-consumer marketing, we could potentially face challenges in maintaining our good relationships with ECPs, who may view our direct-to-consumer marketing as a threat to their business.

In our surgical business, ophthalmic surgeons play a significant role in determining the course of treatment and, ultimately, the type of products that will be used to treat a patient for cataracts, vitreoretinal conditions, refractive errors and glaucoma, among other things. As a result, it is important for us to properly and effectively market our surgical products to surgeons. Acceptance of our surgical products also depends on our ability to train ophthalmic surgeons and their clinical staff on the safe and appropriate use of our products, which takes time. This training process may take longer than expected and may therefore affect our ability to increase sales. Following completion of training, we rely on the trained ophthalmic surgeons to advocate the benefits of our products in the broader marketplace. Convincing ophthalmic surgeons to dedicate the time and energy necessary for adequate training is challenging, and we may not be successful in these efforts. If we are not successful in convincing ophthalmic surgeons of the merits of our products or educating them on the use of our products, they may not use our products and we will be unable to fully commercialize or profit from such products.

We balance the need to maintain inventory levels that are sufficient to ensure competitive lead times against the risk of inventory obsolescence because of changing customer requirements, fluctuating commodity prices, changes to our products, product transfers or the life cycle of our products. To successfully manage our inventories, we must estimate demand from our customers and produce products in sufficient quantity that substantially corresponds to that demand. If we fail to adequately forecast demand for any product, or fail to determine the optimal product mix for production purposes, we may face production capacity issues in manufacturing sufficient quantities of a given product, such as our IOLs, daily contact lenses or certain ocular health products.product. In addition, failures in our information technology systems, issues created by the implementation of our new ERP system or human error could also lead to inadequate forecasting of our overall demand or product mix.

As the number of unique products (SKUs) we offer grows, particularly an increasing number of IOL and contact lens styles with varying diopters, the demand forecasting precision required for us to avoid production capacity issues will also increase. Accordingly, the continued proliferation of unique SKUs in our surgical and vision care portfolios could increase the risk of product unavailability and lost sales. Moreover, an increasing number of SKUs could increase global inventory requirements, especially for consigned products such as IOLs, negatively impacting our working capital performance and leading to write-offs due to obsolescence and expired products.

Compounding the risk of inaccurate forecasts, the manufacturing process for our products has lengthy lead times to acquire and install new equipment and product lines to ramp up production. Thus, if we fail to adequately forecast demand, then we may be unable to scale production in a timely manner to meet unexpected higher demand.

Finally, a significant portion of our vision care products are sold to major healthcare distributors and major retail chains in certain markets. Consequently, our sales and quarterly growth comparisons, as well as our estimates for required inventory levels, may be affected by fluctuations in the buying patterns of such buyers. These fluctuations may result from seasonality, pricing, a recall of a competitor’s product, large retailers' and distributors' buying decisions or other factors. If we overestimate demand and produce too much of a particular product, we face a risk of inventory obsolescence, leaving us with inventory that we cannot sell profitably or at all. By contrast, if we underestimate demand and produce insufficient quantities of a product, we could be forced to choose between producing additional unexpected quantities of that product at a higher price or foregoing sales.

We are engagedhighly dependent upon skilled personnel in manufacturing and sourcing of products and materials on a global scale. Our operations and thosekey parts of our suppliers organization, and we invest heavily in recruiting, training and retaining qualified individuals, including significant efforts to enhance the diversity of our workforce. The loss of the service of key members of our organization—including senior members of our scientific and management teams, high-quality researchers and development specialists and skilled personnel in developing countries—could delay or prevent the achievement of major business objectives.

In addition, our ability to hire qualified personnel also depends on the flexibility to reward superior performance and to pay competitive compensation. Laws, regulations and customary practice on executive compensation, including legislation and customary practice in our home country, Switzerland, may restrict our ability to attract, motivate and retain the required level of qualified personnel. For example, pay benchmarks for Swiss and other European companies may be disrupted byinconsistent with the current market in the United States, making it more difficult to recruit US talent. Further, certain associates will be required to travel frequently between Switzerland and the US. These associates may be unwilling or unable to make such a commitment. Finally, changes to immigration policies in the numerous countries in which we operate, including the United States, as well as restrictions on global travel as a result of local or global public health crises requiring quarantines or other precautions to limit exposure to infectious diseases, may limit our ability to hire or retain talent in, or transfer talent to, specific locations.

Finally, our business, particularly the manufacturing of our products, requires a substantial number of factors, including: disruptionspersonnel. Any failure to retain stable and dedicated labor by us may lead to disruption to our business operations, including the manufacturing of our products. Although we have not experienced any material labor shortage to date, we have observed an overall tightening and increasingly competitive labor market. We have experienced, and expect to continue to experience, increases in logistics; strikeslabor costs to remain competitive in retaining talent. If we are unable to manage and control our labor costs, our business, financial condition and results of operations may be materially and adversely affected.

Financial markets may adversely affect our earnings, the return on our financial investments and the value of some of our assets. For example, inflation could continue to accelerate, which could lead to higher interest rates, increasing our costs of raising capital. Uncertainties around future central bank and other labor disputes; losseconomic policies in the United States and EU, as well as high debt levels in certain other countries, could also impact world trade. Sudden increases in economic, currency or impairment of key manufacturing sites; loss of key suppliers; supplier capacity constraints; raw materialfinancial market volatility in different countries have also impacted, and product quality or safety issues; industrial accidents or other occupational healthmay continue to impact, our business and safety issues; the impact on our suppliers of tighter credit or capital markets; epidemics and pandemics; and natural and man-made disasters, including climatic events (including any potential effect of climate change), power grid failures, acts of war or terrorism, political unrest, fires or explosions and other external factors over which we have no control.

Changes in exchange rates between the US dollar, our reporting currency and other currencies can also result in significant increases or rely on limited sources of supply for many components, raw materialsdecreases in our reported sales, costs and production services, suchearnings as sterilization, usedexpressed in US dollars, and in the productionreported value of our products. The lossassets, liabilities and cash flows. Despite any measures we may undertake in the future to reduce, or hedge against, foreign currency exchange risks, because a significant portion of one of these suppliers orour earnings and expenditures are in currencies other than the inability ofUS dollar, and the fact that our expenditures in Swiss francs and US dollars are significantly higher than our revenue in Swiss francs and US dollars, respectively, any such supplier to meet performanceexchange rate volatility may negatively and quality specifications, requested quantities or delivery schedules could causematerially impact our business, results of operations and financial condition, and may impact the reported value of our net sales, earnings, assets and profitability to decline and have a negative impactliabilities.

Any facility closures or disruption to the operations of these EtO suppliersforeign currency. Such exchange controls could delay or preventlimit our ability to commercializedistribute retained earnings from our products and leadlocal affiliates, or to product back orders for our customers, which could have a materially negative impact on our sales and profitability. In addition, any regulatory enforcement activities against us for our use of EtO could result in financial, legal, business and reputational harm to us. The need to sterilize equipment and personal protective equipment to combat COVID-19 has exacerbated the shortage of EtO. Moreover, a price increasepay intercompany payables due from a supplier where we do not have a supply alternative could cause our profitability to decline if we cannot increase our prices to our customers. To ensure sufficient supply, we may determine that we need to provide financing to some of our single-source suppliers, which could increase our financial exposure to such suppliers.

We have outstanding debt of $4.1 billion as of December 31, 2020,2021, and we may incur additional indebtedness in the future for various reasons, including fluctuations in operating results, capital expenditures and potential acquisitions.

Our indebtedness may:

The occurrence of any one of these events could have a material adverse effect on our business, financial condition or result of operations or cause a significant decrease in our liquidity and impair our ability to pay amounts due on our indebtedness.

We may need to raise additional funds to:

If we raise additional funds by issuing equity or convertible debt securities, the percentage ownership of our then-existing shareholders may be diluted, and holders of these securities may have rights, preferences or privileges senior to those of our then-existing shareholders.

We rely on a combination of patents, trademarks and copyrights to protect our intellectual property. The scope, strength and duration of those intellectual property rights can vary significantly from product to product and country to country. We also rely on a variety of trade secrets, know-how and other confidential information to supplement these protections. In the aggregate, these intellectual property rights are of material importance to our business.

The protections afforded by these intellectual property rights may limit the ability of competitors to commercialize products covered by the applicable intellectual property rights, but they do not prevent competitors from marketing alternative products that compete with our products. In addition, these intellectual property rights may be challenged by third parties and regulatory agencies, and intellectual property treated as trade secrets and protected through confidentiality agreements may be independently developed by third parties and/or subject to misappropriation by others. Furthermore, in certain countries, particularly in China, due to ambiguities in the law and enforcement difficulties, intellectual property rights may not be as effective as in Western Europe or the United States. Therefore, even if we protect our intellectual property to the fullest extent permitted by applicable law, competitors and other third parties may nonetheless develop and commercialize products similar or identical to ours, which could impair our ability to compete and have an adverse effect on our business, financial condition and results of operations.

We, from time to time, are, and may in the future be, subject to various investigations and legal proceedings that arise or may arise.

We also periodically receive inquiries from antitrust and competition authorities in various jurisdictions and, from time to time, are named as a defendant in antitrust lawsuits. For example, since the first quarter of 2015, more than 50 putative class action complaints have been filed in several courts across the US naming as defendants contact lens manufacturers, including Alcon, and alleging violations of federal antitrust law, as well as the antitrust, consumer protection and unfair competition laws of various states, in connection with the implementation of unilateral price policies by the defendants in the sale of contact lenses. The cases have been consolidated in the Middle District of Florida by the Judicial Panel on Multidistrict Litigation and the claims are being vigorously contested. See "Item 8. Financial Information—8.A. Consolidated Statements and Other Financial Information—Legal Proceedings".

In addition, from time to time, we are named as a defendant in product liability lawsuits and, to the extent we are, we may in the future incur material liabilities relating to such product liability claims, including claims alleging product defects and/or alleged failure to warn of product risks. The risk of material product liability litigation is increased in connection with

Because of our extensive international operations, we could be adversely affected by violations of worldwide anti-bribery laws, including those that prohibit companies and their intermediaries from making improper payments to government officials or other third parties for the purpose of obtaining or retaining business, such as the US Foreign Corrupt Practices Act (the “FCPA”),FCPA, and laws that prohibit commercial bribery. Our internal control policies and procedures may not always protect us from reckless or criminal acts committed by our associates or agents. Violations of these laws, or allegations of such violations, could disrupt our business and adversely affect our reputation and our business, results of operations, cash flows and financial condition.

Substantial, complex or extended litigation could cause us to incur large expenditures, affect our ability to market and distribute our products and distract our management. For example, intellectual property litigation in which we are named as a defendant from time to time could result in significant damage awards and injunctions that could prevent the manufacture and sale of the affected products or require us to make significant royalty payments to continue to sell the affected products. Lawsuits by associates, shareholders, customers or competitors, or potential indemnification obligations and limitations of our director and officer liability insurance, could be very costly and substantially disrupt our business. Disputes with such companies or individuals from time to time are not uncommon, and we may be unable to resolve such disputes on terms favorable to us.

Even meritless claims could subject us to adverse publicity, hinder us from securing insurance coverage in the future or require us to incur significant legal costs. As a result, significant claims or legal proceedings to which we are a party could have a material adverse effect on our business, prospects, financial condition and results of operations.

We are obligated to comply with the laws of all of the countries around the world in which we operate and sell products. These laws cover an extremely wide and growing range of activities. Such legal requirements can vary from country to country and new requirements may be imposed on us from time to time as government and public expectations regarding acceptable corporate behavior change, and enforcement authorities modify interpretations of legal and regulatory provisions and change enforcement priorities. In addition, our associates, independent contractors, consultants, commercial partners and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, in violation of such laws and public expectations.

For example, we are faced with increasing pressures, including new laws and regulations from around the world, to be more transparent with respect to how we do business, including with respect to our interactions with healthcare professionals and organizations. These laws and regulations include requirements that we disclose payments or other transfers of value made to healthcare professionals and organizations, including by our associates or third parties acting on our behalf, as well as with regard to the prices for our products. We are also subject to certain privacy laws, including Swiss privacy laws, the EU's General Data Protection Regulation and the California Consumer Privacy Act, which include operational and compliance requirements that are different than those previously in place and also includes significant penalties for non-compliance.

In addition, we have significant activities in a number of developing countries around the world, both through our own associates and through third parties retained to assist us. In some of these countries, a culture of compliance with law may not be as fully developed as in other countries.

To help us in our efforts to comply with the many requirements that impact us, we have a significant global ethics and compliance program in place, and we devote substantial time and resources to efforts to conduct our business in a lawful and publicly acceptable manner. Nonetheless, our ethics and compliance program may be insufficient or associates may fail to comply with the training they received, and any actual or alleged failure to comply with law or with heightened public expectations could lead to substantial liabilities that may not be covered by insurance, or to other significant losses, and could affect our business, financial position and reputation.

In particular, in recent years, there has been a trend of increasing government investigations, legal proceedings and law enforcement activities against companies and executives operating in our industry. Increasingly, such activities can involve criminal proceedings and can retroactively challenge practices previously considered to be acceptable. For instance, in 2017 and 2018, Alcon and Novartis, as well as certain present and former executives and associates of Alcon and Novartis, received document requests and subpoenas from the DoJ and the SEC requesting information concerning Alcon accounting, internal controls and business practices in Asia and Russia, including revenue recognition for surgical equipment and related products and services and relationships with third-party distributors, both before and after Alcon

For additional information, including with respect to certain Novartis obligations to indemnify Alcon, see "Item 8. Financial Information—8.A. Consolidated Statements and Other Financial Information—Legal Proceedings". and "—If we breach the Deferred Prosecution Agreement with the US Department of Justice, then resulting actions by the DoJ could have a material adverse effect on our business, financial condition, results of operations or cash flows."

Such proceedings are inherently unpredictable, and large judgments or penalties sometimes occur. As a consequence, we may in the future incur judgments or penalties that could involve large cash payments, including the potential repayment of amounts allegedly obtained improperly and other penalties, including enhanced damages. In addition, such proceedings may affect our reputation, create a risk of potential exclusion from government reimbursement programs and may lead to civil litigation. As a result, having taken into account all relevant factors, we may in the future enter into major settlements of such claims without bringing them to final legal adjudication by courts or other such bodies, despite having potentially significant defenses against them, in order to limit the risks they pose to our business and reputation. Such settlements may require us to pay significant sums of money and to enter into corporate integrity or similar agreements intended to regulate company behavior for a period of years, which can be costly to operate under.

Any such judgments or settlements, and any accruals that we may take with respect to potential judgments or settlements, could have a material adverse impact on our business, financial condition or results of operations, as well as on our reputation.

The manufacturing and marketing of medical devices, including surgical equipment and instruments and pharmaceuticals, involve an inherent risk that our products may prove to be defective and cause a health risk. We are also subject to a number of laws and regulations requiring us to report adverse events associated with our products. Such adverse events

and potential health risks identified in our monitoring efforts or from ongoing clinical studies may lead to voluntary or mandatory market actions, including recalls, product withdrawals or changes to the instructions for using our devices.

Governmental authorities throughout the world, including the FDA, have the authority to require the recall of our commercialized products in the event of material deficiencies or defects in, for example, design, labeling or manufacture.

We may also voluntarily initiate certain field actions, such as a correction or removal of our products in the future as a result of component failures, manufacturing errors, design or labeling defects or other deficiencies and issues. If a correction or removal of one of our devices is initiated to reduce a health risk posed by the device, or to remedy a violation of the Federal Food, Drug, and Cosmetic Act ("FDCA") caused by the device that may present a risk to health, the correction or removal must be reported to the FDA. Similarly, field actions conducted for safety reasons in the European Economic Area must be reported to the regulatory authority in each country where the field action occurs.

We have voluntarily taken products off the market in the past, including the global voluntary market withdrawal of the CyPass micro-stent. In the year ended December 31, 2018, we recognized an impairment charge of $337 million in relation to the CyPass micro-stent market withdrawal. Based on this experience, we believe that the occurrence of a recall could result in significant costs to us, potential disruptions in the supply of our products to our customers and adverse publicity, all of which could harm our ability to market our products. A recall of one of our products or a similar competing product manufactured by another manufacturer could impair sales and subsequent regulatory approvals of other similar products we market and lead to a general loss of customer confidence in our products. A product recall could also lead to a health authority inspection or other regulatory action or to us being named as a defendant in lawsuits. See "—Litigation, including product liability lawsuits, and governmental investigations may harm our business or otherwise distract our management" above.management."

We are engaged in a multi-year implementation of a new ERP system across our global commercial and manufacturing operations, which is intended to enhance and streamline our existing ERP system. ERP implementations are inherently complex and time-consuming projects that involve substantial expenditures on system software, implementation activities and business process reengineering. Any significant disruption or deficiency in the design and implementation of our new ERP system could adversely affect our ability to process orders, ship our products, provide services and customer support, fulfill contractual obligations or otherwise operate our business. For additional information, see "Item 4. Information on the Company—4.A. History and Development of the Company—Significant Acquisitions, Dispositions and other Events".

We sponsor pension and other post-employment benefit plans in various forms. While most of our plans are now defined contribution plans, certain of our associates remain under defined benefit plans. For these defined benefit plans, we are required to make significant assumptions and estimates about future events in calculating the present value of expected future plan expenses and liabilities. These include assumptions used to determine the discount rates we apply to estimated future liabilities and rates of future compensation increases. Assumptions and estimates we use may differ materially from the actual results we experience in the future due to changing market and economic conditions, higher or lower withdrawal rates or longer or shorter life spans of participants, among other variables. For example, in 2020,2021, a decrease in the interest rate we apply in determining the present value of expected future total defined benefit plan obligations (consisting of pension and other post-employment benefit obligations) of one-quarter of one percent would have increased our year-end defined benefit obligation by $46$38 million. Any differences between our assumptions and estimates and our actual experience could require us to make additional contributions to our pension funds. Further, additional employer contributions might be required if plan funding falls below the levels required by local rules.

Our businesses are subject to varying degrees of governmental regulation in the countries in which we operate, and the general trend is toward increasingly stringent regulation. The exercise of broad regulatory powers by the FDA continues to result in increases in the amounts of testing and documentation required for the commercialization of regulated products and a corresponding increase in the expense of product introduction. Similar trends are also evident in the EU and in other markets throughout the world. Compliance with these laws and regulations is costly and materially affects our business. Among other effects, health care regulations substantially increase the time, difficulty and costs incurred in obtaining and maintaining approval to market newly developed and existing products.

market entry of our products. Even if the FDA or another regulatory agency or notified body approves a product, the approval may limit the indicated uses for a product, may otherwise limit our ability to promote, sell and distribute a product or may require post-marketing studies or impose other post-marketing obligations. We may be unable to obtain the necessary regulatory clearances or approvals for any product on a timely basis or at all. If a regulatory authority delays authorization of a potentially significant product, our market value and operating results may decline. Similarly, if we are unable to obtain regulatory approval or CE marking of our products, we will not be able to market these products, which would result in a decrease in our sales.

We may be unable to successfully maintain the registrations, licenses, clearances or other authorizations we have received or may receive in the future. We also routinely make minor modifications to our products, labeling, instructions for use, manufacturing process and packaging that may trigger a requirement to notify regulatory authorities or to update such registrations or authorizations. This may subsequently require us to manage multiple versions of individual products around the world, depending on the status of any re-registration approvals. Managing such multiple versions may require additional inventory in the form of "bridging stock", extensive redress operations and inventory increases that could exceed our manufacturing capacity or supply chain ability at the time. This could result in prolonged product shortages that could negatively impact our sales, both in terms of any unavailable products and the potential loss of customers that opt for another supplier.

The manufacture of our product portfolio is complex and heavily regulated by governmental health authorities around the world, including the FDA. Whether our products are manufactured at our own dedicated manufacturing facilities or by third parties, we must ensure that all manufacturing processes comply with current Good Manufacturing Practices, quality system requirements and other applicable regulations, as well as with our own high quality standards. In recent years, health authorities have substantially intensified their scrutiny of manufacturers' compliance with such requirements.

Any significant failure by us or our third-party suppliers to comply with these requirements or the health authorities' expectations may cause us to shut down our production facilities or production lines or we could be prevented from importing our products from one country to another. Moreover, if we fail to properly plan for manufacturing capacity, the complexity of our manufacturing process could lead to a long lead time to increase capacity. Any of these events could lead to product shortages, or to our being entirely unable to supply products to customers and consumers for an extended period of time. Such shortages or shutdowns have led to, and could continue to lead to, significant losses of sales revenue and to potential third-party litigation. In addition, health authorities have in some cases imposed significant penalties for such failures to comply with regulatory requirements. A failure to comply fully with regulatory requirements could also lead to a delay in the approval of new products to be manufactured at the impacted site.

The research, development, testing, manufacturing, sale and marketing of our products are subject to extensive governmental regulation. Government regulation includes inspection of and controls over testing, manufacturing, safety and environmental controls, efficacy, labeling, advertising, marketing, promotion, record keeping, tracking, reporting, distributing, import, export, samples, electronic records and electronic signatures.

Among other requirements, we are required to comply with applicable adverse event and malfunction reporting requirements for our products. For example, for our medical device products, in the US, we are required to report to the FDA any incident in which one of our marketed devices may have caused or contributed to a death or serious injury or has malfunctioned and the malfunction of the device or a similar device that we market would be likely to cause or contribute to death or serious injury if the malfunction were to recur. In addition, all manufacturers placing medical devices on the market in the European Economic Area are legally required to report any serious or potentially serious incidents involving devices produced or sold by the manufacturer to the relevant authority in those jurisdictions where any such incident occurred.

Failure to comply with statutes and regulations administered by the FDA and other regulatory bodies or failure to adequately respond to any notices of violation or any similar reports could result in, among other things, any of the following enforcement actions:

If any of these items were to occur, it could result in unanticipated expenditures to address or defend such actions, could harm our reputation and could adversely affect our business, financial condition and results of operations.

We are subject to various global laws pertaining to healthcare fraud and abuse, including anti-kickback laws and physician self-referral laws. For example, the US federal healthcare program anti-kickback statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to induce, or in return for, purchasing, leasing, ordering, arranging for or recommending the purchase, lease or order of any healthcare item or service reimbursable under Medicare, Medicaid or other federally financed healthcare programs. These US laws have been interpreted to apply to arrangements between medical device manufacturers, on the one hand, and prescribers, purchasers, formulary managers and other healthcare-related professionals, on the other hand. The US government may assertlaw provides that a claim includingfor federal healthcare program reimbursement for items or services resulting from a violation of the federal anti-kickback statute constitutes a false or fraudulent claim for purposes of the false claims statutes. Pricing and rebate programs for covered outpatient drugs reimbursed under federal healthcare programs must comply with the Medicaid drug rebate requirements of the Omnibus Budget Reconciliation Act of 1990, as amended, the Veterans Health Care Act of 1992, as amended, and the Deficit Reduction Act of 2005, as amended. The statutes and regulations governing the various price reporting requirements are complex and have changed over time, and the US government has not given clear guidance on many issues. In addition, recent statutory and regulatory developments have not yet been applied by the government or courts to specific factual situations. We believe that we are in compliance with all applicable government price reporting requirements, but there is the potential that the Centers for Medicare & Medicaid Services ("CMS"), other regulatory and law enforcement agencies or a court could arrive at different interpretations, with adverse financial or other consequences for us. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. All of these activities are also potentially subject to federal and state consumer protection and unfair competition laws. Some European Union bodies and most European Union member states and Japan impose controls and restrictions that are similar in nature or effect to those described above.

In recent years, the US government and several US states have enacted legislation requiring medical device companies to establish marketing compliance programs and file other periodic reports. Similar legislation is being considered in other US states. Many of these requirements are new and uncertain, and available guidance is limited. We could face enforcement action, fines and other penalties and could receive adverse publicity, all of which could harm our business, if it is alleged that we have failed to fully comply with such laws and regulations. Similarly, if the physicians or other providers or entities that we do business with are found to have not complied with applicable laws, they may be subject to sanctions, which could also have a negative impact on our business.

denial or withdrawal of pre-marketing product approvals, private "qui tam" actions brought by individual whistleblowers in the name of the government, or refusal to allow us to enter into supply contracts, including government contracts, any of which could have a material adverse effect on our business, financial condition or results of operations.

The global regulatory environment is increasingly stringent and unpredictable. Unexpected changes can have an adverse impact on our business, financial condition and results of operations.

First, it could be costly and onerous to comply with changes or new requirements relating to the regulatory approval process or postmarket requirements applicable to our products in various jurisdictions. As discussed in "Item 4. Information on the Company—4.B. Business Overview—Government Regulation—Product Approval and Monitoring" the EU has made recent changes to its regulatory regime. In addition, several countries that did not have regulatory requirements for medical devices have established such requirements in recent years, and other countries have expanded, or plan to expand, their existing regulations. While harmonization of global regulations has been pursued, requirements continue to differ significantly among countries. Further, the FDA is also pursuing various efforts to modernize its regulation of devices, including potential changes to the 510(k) pathway such as limiting reliance on older predicate devices and establishing an alternative 510(k) pathway that permits reliance on objective performance criteria. We expect this global regulatory environment to continue to evolve, which could impact the cost of, the time needed to approve and, ultimately, our ability to maintain existing approvals or obtain future approvals for, our products.

Second, new legislation and new regulations and interpretations of existing health care statutes and regulations are frequently adopted, any of which could affect our future business and results of operations. For example, in the US, there have been a number of health care reform legislative and regulatory measures proposed and adopted at the federal and state government levels that affect the health care system generally and that have had significant impact on our business.

Third, changes to current regulations in certain countries, including the United States, requiring a prescription for the purchase of contact lenses could have a significant impact on the way we market and distribute contact lens and contact lens care products, by limiting the role of the ECP as an intermediary in the sale of our vision care products. Such changes could require us to incur significant costs to update our marketing and distribution methodologies and could adversely affect the sales of our vision care products.

Finally, within our surgical business, a considerable portion of our sales and sales growth rely on patient-pay premium technologies, in markets where access to these technologies has been established. For example, in the US, two landmark rulings issued by the CMS established a bifurcated payment system for certain of our AT-IOLs pursuant to which part of the cost of the cataract surgery with such AT-IOLs would be reimbursed under Medicare, with the remaining cost paid out-of-pocket. For more details, see "Item 4. Information on the Company—4.B. Business Overview—Our Products—Surgical". To the extent regulatory bodies in the US, such as CMS, or other health authorities outside the US, decide to amend the regulations governing patient-pay reimbursement for advanced technologies, our sales and sales growth could be negatively impacted.

We are subject to numerous national and local environmental, health and safety laws and regulations, including relating to the discharge of regulated materials into the environment, human health and safety, laboratory procedures and the generation, handling, use, storage, treatment, release and disposal of hazardous materials and wastes. Our operations involve the use of hazardous and flammable materials, including chemicals and biological materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these hazardous materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our generation, handling, use, storage, treatment, release or disposal of hazardous materials or wastes, we could be held liable for any resulting damages, and any liability could materially adversely affect our business, operating results or financial condition. Our insurance may not provide adequate coverage against potential liabilities. If we fail to comply with applicable environmental, health and safety laws and regulations, we may face significant administrative, civil or criminal fines, penalties or other sanctions. In addition, we may incur substantial costs to comply with current or future environmental, health and safety laws and regulations, which have tended to become more stringent over time, including any potential laws and regulations that may be implemented in the future to address global climate change concerns. Compliance with current or future environmental, health and safety laws and regulations may increase our costs or impair our research, development or production efforts.

While operating as a division of Novartis, our subsidiary, Alcon Pharmaceuticals Ltd. (“APL”), benefited from an investment tax incentive granted by the Swiss State Secretariat for Economic Affairs in Switzerland and the Canton of Fribourg, Switzerland in respect of both Swiss federal taxes and Fribourg cantonal / communal taxes for the fiscal years ended

In connection with the Spin-off, our former parent retained certain assets of APL related to APL’s former pharmaceutical business. As a result, Novartis agreed with the Canton of Fribourg that each of APL and a subsidiary of Novartis (Novartis Ophthalmics AG, Fribourg) will have separate and standalone obligations and potential liabilities in connection with the five year claw-back period relating to the Fribourg investment tax incentive granted to APL. In particular, APL may be required to pay a "claw-back" amount of up to CHF 1.3 billion to the Fribourg tax authorities if APL fails to continue certain business activities in Fribourg and if Alcon Inc., APL and Alcon Services AG fail to (i) remain tax resident in Fribourg, and (ii) employ a certain minimum number of associates in Fribourg. Since December 31, 2018, our "claw-back" obligation has begun to be reduced each year by 20% of the original maximum amount and will expire on December 31, 2022. As of December 31, 2020,2021, the "claw-back" obligation amounted to CHF 520260 million.

We intend to conduct APL's operations so as to comply with these requirements in all respects; however, we may be unable to meet, or the Canton of Fribourg may successfully challenge our compliance with, these requirements. If the Canton of Fribourg successfully challenges our compliance with these requirements, we would be required to pay all or a portion of the "claw-back" amount.

We conduct operations in multiple tax jurisdictions, and the tax laws of those jurisdictions generally require that the transfer prices between affiliated companies in different jurisdictions be the same as those between unrelated companies dealing at arm's length and that such prices are supported by contemporaneous documentation. While we believe that we operate in compliance with applicable transfer pricing laws and intend to continue to do so, our transfer pricing procedures are not binding on applicable tax authorities. If tax authorities in any of these jurisdictions were to successfully challenge our transfer prices as not reflecting arm's length transactions, they could require us to adjust our transfer prices and thereby reallocate our income to reflect these revised transfer prices, which could result in a higher overall tax liability to us and possibly interest and penalties.

Additionally, the integrated nature of our worldwide operations can produce conflicting claims from tax authorities in different countries as to the profits to be taxed in the individual countries. The majority of the jurisdictions in which we operate have double tax treaties with other foreign jurisdictions, which provide a framework for mitigating the impact of double taxation on our revenues and capital gains. However, mechanisms developed to resolve such conflicting claims are largely untested, can be expected to be very lengthy and do not always contain a mandatory dispute resolution clause.

In recent years, tax authorities around the world have increased their scrutiny of company tax filings and have become more rigid in exercising any discretion they may have. As part of this, the Organization for Economic Co-operation and Development ("OECD") has proposed certain changes to the International tax standards that have resulted and will continue to result in local tax law changes under its Base Erosion and Profit Shifting ("BEPS") Action Plans to address issues of transparency, coherence and substance. Most recently, the OECD has released its plans for proposing further amendments to the international tax standards, including a new attribution of the right to tax corporate profits where customers are located and a mechanism ensuring that all corporate profits would be subject to a minimum taxation level. In December 2021, the OECD released preliminary guidance as to how to calculate the minimum 15% tax rate that multinational companies are expected to be subject to in each country they operate in. These rules, when enacted, are likely to lead to an increase of our tax expense and effective tax rate.

Furthermore, Switzerland and the various Swiss cantons in which Alcon is present have adopted their own corporate tax reform. The main elements of the Swiss tax reform became effective in 2020 and have resulted in an increase in Alcon’s tax burden and effective tax rate in Switzerland.

In general, tax reform efforts, including with respect to tax base or rate, transfer pricing, intercompany dividends, cross border transactions, controlled corporations and limitations on tax relief allowed on the interest on intercompany debt, will require us to continually assess our organizational structure and could lead to an increased risk of international tax disputes, an increase in our effective tax rate and an adverse effect on our financial condition.

We carry a significant amount of goodwill and other intangible assets on our consolidated balance sheet,Consolidated Balance Sheet, primarily due to the value of the Alcon brand name, but also intangible assets associated with our technologies, acquired research and development, currently marketed products and marketing know-how. As a result, we may incur significant noncash impairment charges if the fair value of the intangible assets and the groupings of cash generating units containing goodwill would be less than their carrying value on our consolidated balance sheetConsolidated Balance Sheet at any point in time. For example, in 2021, we recognized $225 million in impairment charges.

For a detailed discussion of how we determine whether an impairment has occurred, what factors could result in an impairment and the impact of impairment charges on our results of operations, see "Note 3. Selected Accounting Policies—Goodwill and intangible assets—Impairment of goodwill, Alcon brand name and definite lived intangible assets" to our Consolidated Financial Statements included elsewhere in this Annual Report.

Increasingly, in addition to the importance of their financial performance, companies are being judged by their performance on a variety of environmental, social and governance ("ESG") matters, which are considered to contribute to the long-term sustainability of companies’ performance.

A variety of organizations measure the performance of companies on such ESG topics, and the results of these assessments are widely publicized. In addition, investment in funds that specialize in companies that perform well in such assessments are increasingly popular, and major institutional investors have publicly emphasized the importance of such ESG measures to their investment decisions. Topics taken into account in such assessments include, among others, the company’s efforts and impacts on climate change and human rights, diversity and inclusion, ethics and compliance with law and the role of the company’s board of directors in supervising various sustainability issues. In addition to the topics typically considered in such assessments, in the healthcare industry, issues of the public’s ability to access our products and solutions are of particular importance.

We actively manage a broad range of such ESG matters, taking into consideration their expected impact on the sustainability of our business over time and the potential impact of our business on society and the environment. However, in light of investors’ increased focus on ESG matters, there can be no certainty that we will manage such issues successfully, or that we will successfully meet society’s expectations as to our proper role. Any failure or perceived failure by us in this regard could have a material adverse effect on our reputation and on our business, share price, financial condition or results of operations, including the sustainability of our business over time.

In the future, your percentage ownership in Alcon may be diluted because of equity issuances from acquisitions, capital markets transactions or otherwise, including equity awards that we may grant to our directors, officers and associates under our associate participation plans. These additional issuances will have a dilutive effect on our earnings per share, which could adversely affect the market price of our shares.

Our shares trade on the NYSE in US dollars and on the SIX in Swiss francs, which may result in price differentials between the two exchanges for a variety of factors, including fluctuations in the US dollar/Swiss franc exchange rate and differences in trading schedules.

Although Alcon expects that it will continue to recommend the payment of a regular cash dividend based upon the prior year’s core net income, we may not pay or declare dividends in the future. Due to the economic uncertainties resulting from the COVID-19 pandemic, our Board chose to recommend not paying a dividend in 2020. The declaration, timing and amount of any dividends to be paid by Alcon will be subject to the approval of shareholders at the relevant General Meeting of shareholders. The determination by the Board as to whether to recommend a dividend and the approval of any such proposed dividend by the shareholders will depend upon many factors, including our financial condition, earnings, corporate strategy, capital requirements of our operating subsidiaries, covenants, legal requirements and other factors deemed relevant by the Board and shareholders.

In addition, any dividends that we may declare will be denominated in Swiss francs. Consequently, exchange rate fluctuations will affect the US dollar equivalent of dividends received by holders of shares held via DTC or shares directly registered with Computershare Trust Company, N.A. in the US If the value of the Swiss franc decreases against the US dollar, the value of the US dollar equivalent of any dividend will decrease accordingly.

We report under the Securities Exchange Act of 1934, as amended ("Exchange Act"), as a non-US company with foreign private issuer status. Because we qualify as a foreign private issuer under the Exchange Act and although we are subject to Swiss laws and regulations with regard to such matters and intend to continue to furnish quarterly financial information to

the SEC, we are exempt from certain provisions of the Exchange Act that are applicable to US domestic public companies, including (i) the sections of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the Exchange Act, (ii) the sections of the Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time and (iii) the rules under the Exchange Act requiring the filing with the SEC of quarterly reports on Form 10-Q containing unaudited financial and other specified information, or current reports on Form 8-K, upon the occurrence of specified significant events. In addition, foreign private issuers are not required to file their annual report on Form 20-F until four months after the end of each financial year, while US domestic issuers that are large accelerated filers are required to file their annual report on Form 10-K within 60 days after the end of each fiscal year. Foreign private issuers are also exempt from the Regulation Fair Disclosure, aimed at preventing issuers from making selective disclosures of material information.

In addition, as a foreign private issuer, we are entitled to rely on exceptions from certain corporate governance requirements of the NYSE. As a result of the above, you may not have the same protections afforded to shareholders of companies that are not foreign private issuers.

Furthermore, we prepare our financial statements under IFRS. There are, and may continue to be, certain significant differences between IFRS and US Generally Accepted Accounting Principles, or US GAAP, including but not limited to potentially significant differences related to the accounting and disclosure requirements relating to associate benefits, nonfinancial assets, taxation and impairment of long-lived assets. As a result, our financial information and reported earnings for historical or future periods could be significantly different if they were prepared in accordance with US GAAP, and you may not be able to meaningfully compare our financial statements under IFRS with those companies that prepare financial statements under US GAAP.

We are a foreign private issuer and therefore we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act applicable to US domestic issuers. To maintain our status as a foreign private issuer, either (a) a majority of our shares must be directly or indirectly owned of record by non-residents of the United States or (b)(i) a majority of our executive officers or directors may not be United States citizens or residents, (ii) more than 50 percent of our assets cannot be located in the United States and (iii) our business must be administered principally outside the United States.

If we were to lose our foreign private issuer status, we would be required to comply with the Exchange Act reporting and other requirements applicable to US domestic issuers, which are more detailed and extensive than the requirements for foreign private issuers. For instance, we would be required to change our basis of accounting from IFRS as issued by the IASB to US GAAP, which we expect would be difficult and costly and could also result in potentially material changes to historical financial statements previously prepared on the basis of IFRS. We may also be required to make changes in our corporate governance practices in accordance with various SEC and NYSE rules. The regulatory and compliance costs to us under US securities laws could be significantly higher than the costs we will incur as a foreign private issuer. As a result, a loss of foreign private issuer status would increase our legal and financial compliance costs and would make some activities highly time-consuming and costly. If we were required to comply with the rules and regulations applicable to US domestic issuers, it would make it more difficult and expensive for us to obtain director and officer liability insurance, and we could be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These rules and regulations could also make it more difficult for us to attract and retain qualified members of our Board.

Swiss law reserves for approval by shareholders certain corporate actions over which a board of directors would have authority in some other jurisdictions. For example, shareholders must approve the payment of dividends and cancellation of treasury shares. Swiss law also requires that our shareholders themselves resolve to, or authorize our Board to, increase our share capital. While our shareholders may authorize share capital that can be issued by our Board without additional shareholder approval, Swiss law limits this authorization to 50% of the issued share capital at the time of the authorization. The authorization, furthermore, has a limited duration of up to two years and must be renewed by the shareholders from time to time thereafter in order to be available for raising capital. Additionally, Swiss law grants pre-

as do the laws of some other jurisdictions. These Swiss law requirements relating to our capital management may limit our flexibility, and situations may arise where greater flexibility would have provided benefits to our shareholders.

We are organized under the laws of Switzerland. As a result, it may not be possible for investors to effect service of process within the United States upon us or upon such persons or to enforce against them judgments obtained in US courts, including judgments in actions predicated upon the civil liability provisions of the federal securities laws of the United States. We have been advised by our Swiss counsel that there is doubt as to the enforceability in Switzerland of original actions, or in actions for enforcement of judgments of US courts, of civil liabilities to the extent predicated upon the federal and state securities laws of the United States. Original actions against persons in Switzerland based solely upon the US federal or state securities laws are governed, among other things, by the principles set forth in the Swiss Federal Act on International Private Law. This statute provides that the application of provisions of non-Swiss law by the courts in Switzerland shall be precluded if the result is incompatible with Swiss public policy. Also, mandatory provisions of Swiss law may be applicable regardless of any other law that would otherwise apply.

Switzerland and the United States do not have a treaty providing for reciprocal recognition and enforcement of judgments in civil and commercial matters. The recognition and enforcement of a judgment of the courts of the United States in Switzerland are governed by the principles set forth in the Swiss Federal Act on Private International Law. This statute provides in principle that a judgment rendered by a non-Swiss court may be enforced in Switzerland only if:

We generally organize our manufacturing facilities along product categories, with most plants being primarily dedicated to the manufacture of either our Surgical or Vision Care product offerings. As of December 2020,2021, we employed approximately 4,000 people to manufacture surgical products at 10 facilities in the US, Belgium, Switzerland, Ireland, Germany and Israel and approximately 5,3005,500 people to manufacture Vision Care products at eight facilities in the US, Germany, Singapore, Malaysia and Indonesia. Our functional division of plants reflects the unique differences in regulatory requirements governing the production of surgical medical devices as well as the different technical skills required of associates in these manufacturing environments. All of our manufacturing plants are ISO 1348513485:2016 and ISO 14001:2015 certified. Currently, we manufacture approximately 90% of our products internally and rely on third-party manufacturers (including Novartis) for a limited number of products.

The goal of our supply chain strategy is to efficiently produce and distribute high quality products. To that end, we employ cost-reduction programs, known as continuous improvement programs, involving activities such as cycle-time reductions,

The manufacture of our products is complex, involves advanced technology and is heavily regulated by governmental health authorities around the world, including the FDA.world. Risks inherent to the medical device industry, specifically as they relate to Class III devices,and pharmaceutical industries are part of our operations. If we or our third-party manufacturers fail to comply fully with regulations, there could be a product recall or other shutdown or disruption of our production activities. We have implemented a global manufacturing strategy to maximize business continuity in case of such events or other unforeseen catastrophic events.

Product quality and patient safety are vitally important for Alcon and our industry. Our customers and patients must always feel safe when using our products. Our Quality Management Systems group ("QMS") is responsible for establishing and maintaining a robust and compliant quality control system across Alcon. QMS regularly monitors industry trends, as well as global and regulatory changes, and adjusts our processes and procedures to adhere to current standards and best practices. In addition, our Quality Compliance group audits our internal processes and suppliers for compliance with approved processes and procedures.

The components used in certain of our Surgical products, such as viscoelastics, and our ocular health products, such as our products for dry eye, are sourced from facilities that meet the regulatory requirements of the FDA or other applicable health regulatory authorities. Because of the proprietary nature and complexity of the production of these components, a number of them are only available from a single or limited number of FDA-approvedhealth regulatory authority-approved sources. The majority of active chemicals, biological raw materials and selected inactive chemicals used in our products are acquired pursuant to long term supply contracts. The sourcing of components used in our Surgical products differs widely due to the breadth and variety of products, with a number of the components sourced from a single or limited number of suppliers. When we rely upon a sole source or limited sources of supply for certain components, we try to maintain a sufficient inventory consistent with prudent practice and production lead-times and to take other steps necessary to ensure our continued supply. The prices of our suppliesraw materials are generally not volatile.stable; however, we continue to monitor established indices for key raw materials and negotiate any price impact with the supplier.

We believe that our patents are important to our business but that no single patent, or group of related patents, currently is of material importance in relation to our business as a whole. Our strategy is to develop patent portfolios for our research and development projects in order to obtain market exclusivity for the innovative features of our products in our major markets. The scope and duration of protection provided by a patent can vary significantly from country to country.

We routinely monitor the activities of our competitors and other third parties with respect to their use of our intellectual property. When appropriate, we will enforce our intellectual property rights to ensure that we are receiving the protections they afford us. Similarly, we will staunchly defend our right to develop and market products against unfounded claims of infringement by others. We will aggressively pursue or defend our position in the appropriate courts if the dispute cannot otherwise be promptly resolved.

In addition to our patents and pending patent applications in the US and selected non-US markets, we rely on proprietary know-how and trade secrets in our businesses and work to ensure the confidentiality of this information, including through the use of confidentiality agreements with associates and third parties. In some instances, we also acquire, or obtain licenses to, intellectual property rights that are important to our businesses from third parties.

All of our major products are sold under trademarks that we consider in the aggregate to be important to our businesses as a whole. We consider trademark protection to be particularly important in the protection of our investment in the sales and marketing of our contact lens care and ocular health products. The scope and duration of trademark protection varies widely throughout the world.
