Item 1. Business




Corning traces its origins to a glass business established in 1851. The present corporation was incorporated in the State of New York in December 1936. The Company’s name was changed from Corning Glass Works to Corning Incorporated on April 28, 1989.


Corning Incorporated is a leading innovator in materials science. For 170 years, Corning has combined its unparalleled expertise in glass science, ceramic science, and optical physics with deep manufacturing and engineering capabilities to develop category-defining products that transform industries and enhance people's lives. We succeed through sustained investment in research and development, a unique combination of material and process innovation, and deep, trust-based relationships with customers who are global leaders in their industries.


Corning’s capabilities are versatile and synergistic, allowing the Company to evolve to meet changing market needs, while also helping customers capture new opportunities in dynamic industries. Today, Corning’s markets include optical communications, mobile consumer electronics, display technology, automotive emissions control, laboratory products and other glass products. Corning's industry-leading products include damage-resistant cover glass for mobile devices; precision glass for advanced displays; optical fiber and cable, wireless technologies, and connectivity solutions for state-of-the-art communications networks; trusted products to accelerate drug discovery and delivery; and clean-air technologies for cars and trucks.


Corning operates in five reportable segments: Display Technologies, Optical Communications, Specialty Materials, Environmental Technologies and Life Sciences, and manufactures products at 119 plants in 15 countries.


Display Technologies Segment


Corning’s Display Technologies segment manufactures glass substrates for flat panel displays, including liquid crystal displays (“LCDs”) and organic light-emitting diodes (“OLEDs”) that are used primarily in televisions, notebook computers, desktop monitors, tablets and handheld devices.  This segment develops, manufactures, and supplies high quality glass substrates using technology expertise and a proprietary fusion manufacturing process, which Corning invented and is the cornerstone of the Company’s technology leadership in the display glass industry.  Our highly automated process yields glass substrates with a pristine surface and excellent thermal stability and dimensional uniformity – essential attributes in the production of large, high-performance display panels.  Corning’s fusion process is scalable and we believe it is the most cost-effective process in producing large size substrates.




We are recognized as a world leader in precision glass innovations that enable our customers to produce larger, thinner, more flexible, and higher-resolution displays. Some of the product innovations we have launched over the past ten years utilizing our world-class processes and capabilities include the following:


Corning® EAGLE XG® Slim Glass, Corning’s flagship glass product enabling thinner televisions and monitors with larger-sized screens; it is trusted by the world’s leading panel makers for LCD displays with more than 35 billion square feet sold;

Corning Astra® Glass, an innovative glass solution designed to meet the emerging needs for high-resolution displays. This glass is designed for oxide backplanes, but enables a range of applications made using traditional aluminosilicate to specific low temperature polysilicon processes;

Corning Lotus™ NXT Glass, a high-performance display glass designed to withstand high-temperature processing requirements enabling highest-resolution displays in smaller and flexible devices; and

The world’s first Gen 10 and Gen 10.5 glass substrate sizes in support of improved efficiency in manufacturing large-sized displays.


Corning has display glass manufacturing operations in China, South Korea, Japan and Taiwan, and services its glass customers in all regions, utilizing its manufacturing facilities throughout Asia.


Patent protection and proprietary trade secrets are important to the Display Technologies segment’s operations. Refer to the material under the heading “Patents and Trademarks” for information relating to patents and trademarks.


The Display Technologies segment represented 26% of Corning’s consolidated net sales in 2021.


Optical Communications Segment


Corning invented the world’s first low-loss optical fiber in 1970. Since that milestone, we have continued to pioneer optical fiber, cable and connectivity solutions. As global demand driven by video usage grows exponentially, telecommunications networks continue to migrate from copper to optical-based systems that can deliver the required cost-effective capacity. Our experience puts us in a unique position to design and deliver optical solutions that reach every edge of the communications network.


This segment is divided into two main product groupings – carrier network and enterprise network. The carrier network group consists primarily of products and solutions for optical-based communications infrastructure for services such as video, data and voice communications. The enterprise network group consists primarily of optical-based communication networks sold to businesses, governments and individuals for their own use.


Our carrier network product portfolio encompasses an array of optical fiber products, including Vascade® optical fibers for use in submarine networks; LEAF® optical fiber for long-haul, regional and metropolitan networks; SMF-28® ULL and TXF® fiber for more scalable long-haul and regional networks; SMF-28e+™ single-mode optical fiber providing additional transmission wavelengths in metropolitan and access networks, and ClearCurve® ultra-bendable single-mode fiber for use in multiple-dwelling units and fiber-to-the-home applications.  For high performance across the range of long-haul, metro, access, and fiber-to-the-home network applications, SMF-28® Ultra and SMF-28® Contour fibers deliver industry-leading attenuation, compatibility, and improved macrobend performance in one fiber. A portion of our optical fiber is sold directly to end users and third-party cablers globally.

Corning is guided by an enduring set of Values that defines our relationship with employees, customers, and our communities:  Quality, Integrity, Performance, Leadership, Innovation, Independence and the Individual.  Our Values are the key to our business success, a source of pride and excitement for our employees, and the factor that ultimately sets us apart from our competitors.  In short, we believe that how we do things is as important as what we do.  We measure how we live our Values through the annual Corporate Values Survey.  We use the results to see what actions can be taken toward better achievement of the Values. Corning employees all contribute to the success of the Company by living our Values—all seven, all the time, all around the world. 


Diversity, Equity and Inclusion


We are focused on leveraging globally diverse teams and creating an inclusive environment for all employees.  Our global workforce is comprised of 61% men and 39% women.  In all regions of the world, we are continuing to invest in building our pipeline of female and underrepresented talent through targeted recruitment efforts, mentoring and coaching programs, networking opportunities, personalized development plans and proactive career management.   As a result of these efforts, we have made significant diversity gains within our leadership teams.  Since 2010, gender and ethnic diversity among members of the Corporate Management Group, which includes about 230 of the Company’s top global leaders, increased from 28% to 50%; corporate officer diverse representation has increased from 21% to 38%. 


In 2021, as planned, we achieved 100% pay equity for all salaried men and women in our worldwide operations and we continued to maintain pay equity across minority groups compared with white salaried employees in the U.S. We furthered our longstanding commitment to diversity, equity and inclusion in 2020 by creating the Office of Racial Equality and Social Unity (ORESU) to further our goal of a more equitable and inclusive culture at Corning and beyond. The efforts of this office have not only impacted policies, practices, communications, and our corporate culture, but have championed diversity and inclusion in the communities in which our employees live and work.  Since its creation, in addition to launching enterprise-wide Unconscious Bias training and entering a $5.5 million strategic partnership with North Carolina A&T University, ORESU is also engaging with local communities to enhance public safety and create places where students of color can thrive.


Corning proudly sponsors 16 different Employee Resource Groups ("ERGs") with 59 chapters worldwide. They represent employees who are women, Black, Asian, Latino, Native American, people with disabilities, members of the LGBTQ+ community, and veterans, among others. The ERGs are vital in raising awareness, recruiting and retaining diverse talent, and inspiring corporate leadership to adopt new policies, practices, and services.


Talent Management


Each year we formally evaluate the talent implications of our strategic business plans and align our actions and objectives accordingly.  As businesses grow organically or through acquisition, we create human capital objectives to ensure we have the right people with the right skills in place to deliver that growth.  In 2021, as a result of these objectives, our talent processes supported the net addition of approximately 11,100 employees worldwide, with significant growth in all regions.




Corning strives to attract and recruit diverse qualified candidates to maintain our culture of innovation and to foster creativity.  We have created a strategic talent pipeline through internships, co-operatives, rotational leadership programs, and partnerships with various universities, including Historically Black Colleges & Universities (HBCUs).  In addition, we collaborate with organizations such as the Society of Women Engineers, The Association of Latino Professionals for America, National Society of Black Engineers, National Association of Black Accountants, Out for Undergrad, and military veterans’ groups to introduce us to qualified, diverse candidates.


Businesses conduct climate surveys at least every two years, and ad hoc pulse surveys as needed, to measure engagement, satisfaction and alignment with our Values.  It is important to Corning that employees develop, grow and are inspired to continue their careers at the Company over the long-term.  We offer rich simulations, assessments, and experiences that are digital, classroom, and a blend of both, targeted to all levels in the organization.  We provide on-the-job learning experience, mentoring, and career planning to ensure immediate application and lasting impact.  Talent retention is an ongoing important focus area which aligns with our strategy of encouraging and supporting longer-term careers with Corning.  Historically, our talent retention has been consistently higher than the markets in which we compete for talent.  Although 2021 yielded some recruitment and retention challenges primarily in specific locations within our US operations, our talent management approach enabled our HR teams to mobilize quickly with plans in place to address those issues.  Salaried talent retention in 2021 was 94%.


At Corning, the health and safety of our workforce is always of paramount consideration.  Our safety standards always meet, and often exceed, local regulatory standards.  We continue to rank within the top quartile of our ORCHSE Strategies, LLC. (a National Safety Council membership-based workplace safety group) peer group in terms of total recordable incident rate (TRIR) performance with a Company-wide TRIR of just 0.50 in 2021.  We promote employee wellbeing through wellness programs which vary by region such as nutrition, mental health, and fitness-related offerings, smoking cessation programs, and smoke free campuses. With the continuation of the pandemic in 2021, we continued our Responsible Corning program with enhanced cleaning, screening, testing and other measures initiated in 2020. In addition, we encouraged COVID vaccinations and boosters among our employees and in the communities in which we operate, supplying more than 100,000 vaccines to employees, families and community members in locations such as Reynosa Mexico, Asan Korea and Pune India.

Item 1A. Risk Factors 


We operate in rapidly changing economic, political, and technological environments that present numerous risks. Our operations and financial results are subject to risks and uncertainties, including those described below, that could adversely affect our business, financial condition, results of operations, cash flows, our ability to successfully execute our strategy and the trading price of our common stock or debt. The following discussion identifies the most significant factors that may adversely affect the Company. This information should be read in conjunction with Management's Discussion and Analysis of Financial Conditions and Results of Operations ("MD&A") and the consolidated financial statements and related notes incorporated by reference into this report. The following discussion of risks is not all inclusive but is designed to highlight what we believe are important factors to consider, as these factors could cause our future results to differ from those in our forward-looking statements and from historical trends.


Risks Related to Our Business

The ongoing COVID-19 pandemic has, and may continue to, adversely impact the global economy and disrupt our operations and supply chains, which may have an adverse effect on our results of operations


COVID-19 has impacted and may further impact the global economy and could have additional impacts on economic growth, the proper functioning of financial and capital markets, foreign currency exchange rates, and interest rates. The pandemic has resulted in authorities around the world implementing numerous unprecedented measures such as travel restrictions, quarantines, shelter in place orders, vaccine mandates and facility shutdowns. These measures have impacted, and may continue to impact our workforce, operations and supply chains, and those of our customers, contract manufacturers and suppliers, particularly in the event of a significant global resurgence of the illness. There is considerable uncertainty regarding the duration, scope and severity of the pandemic and the impacts on our business and the global economy from the effects of the ongoing pandemic and response measures.  


Inflationary price pressures and uncertain availability of commodities, raw materials, utilities, labor or other inputs used by us and our suppliers, or instability in logistics and related costs, could negatively impact our profitability. 


Increases in the price of commodities, raw materials, utilities, labor or other inputs that we or our suppliers use in manufacturing and supplying products, components and parts, along with logistics and other related costs, may lead to higher production and shipping costs for our products, parts, and components. Further, increasing global demand for, and uncertain supply of, such materials could disrupt our or our suppliers’ ability to obtain such materials in a timely manner to meet our supply needs and/or could lead to increased costs. Any increase in the cost of inputs to our production could lead to higher costs for our products and could negatively impact our operating results, future profitability and ability to successfully deliver on our strategy. Increasing prices to our customers to offset the impact of higher costs, may cause certain of our customers to push out, cancel or refrain from purchasing our products, which could materially adversely impact demand for our products, and therefore also negatively impact our operating results, future profitability and ability to successfully deliver on our strategy.


Supply chain disruptions, manufacturing interruptions or delays, or the failure to accurately forecast customer demand, could affect our ability to meet customer demand, lead to higher costs, or result in excess or obsolete inventory; if we are unable to obtain the necessary equipment, raw and batch materials, natural resources or utilities required in our products or processes, our business will be negatively impacted


Corning’s business relies on its timely supply of materials, equipment, services and related products to meet the changing technical and volume requirements of its customers, which depends in part on the timely delivery of materials, equipment and services, from suppliers and contract manufacturers. Significant and sudden increases in demand for such materials, equipment and services, as well as delays in and unpredictability of shipments due to transportation interruptions, have resulted in, and may continue to result in, a shortage of materials, equipment and services needed to manufacture Corning’s products. Such shortages have adversely impacted, and may continue to adversely impact, our suppliers’ ability to meet our demand requirements and Corning’s manufacturing operations and its ability to meet customer demand. Some key materials, equipment and services are subject to long lead-times or available only from a single supplier or limited group of suppliers. Volatility of demand for manufacturing equipment can increase capital, technical, operational and other risks for Corning and for companies throughout our supply chain, and may cause some suppliers to exit businesses, or scale back or cease operations, which could impact our ability to meet customer demand.




Our ability to meet customer demand depends, in part, on our ability to obtain timely and adequate delivery of equipment, raw and batch materials, natural resources or utilities, equipment, parts, components and raw materials from our suppliers. We may experience shortages that could adversely affect our operations. Certain manufacturing equipment, components and raw materials are available only from single or limited sources, and we may not be able to find alternate sources in a timely manner. A reduction, interruption or delay of supply, or a significant increase in the price for supplies, such as manufacturing equipment, precious metals, raw materials, utilities including energy and industrial water, could have a material adverse effect on our business. 


Corning may also experience significant interruptions of its manufacturing operations, delays in its ability to deliver products or services, increased costs or customer order cancellations as a result of:


The failure or inability to accurately forecast demand and obtain sufficient quantities of materials, equipment and services on a cost-effective basis;

Volatility in the availability and cost of materials, equipment and services, including rising prices due to inflation or scarcity of availability;
Difficulties or delays in obtaining required import or export approvals;
Shipment delays due to transportation interruptions or capacity constraints;
A worldwide shortage of semiconductor components as a result of sharp increases in demand for semiconductor products in general;
Information technology or infrastructure failures, including those of a third-party supplier or service provider; and
Natural disasters, the impacts of climate change, or other events beyond Corning’s control (such as earthquakes, utility interruptions, tsunamis, hurricanes, typhoons, floods, storms or extreme weather conditions, fires, regional economic downturns, regional or global health epidemics, including the ongoing COVID-19 pandemic, geopolitical turmoil, increased trade restrictions between the U.S. and China and other countries, social unrest, political instability, terrorism, or acts of war) in locations where it or its customers or suppliers have manufacturing, research, engineering or other operations.


Cornings Display Technologies segment generates a significant amount of the Companys profits and cash flow; any significant decrease in display glass pricing or market share could have a material and negative impact on our financial results


Corning’s ability to generate profits and operating cash flow depends largely on the profitability of our display glass business, which is subject to continuous pricing pressure due to industry competition, potential over-capacity, and development of new technologies. If we are not able to achieve proportionate reductions in costs and/or increases in volume to offset ongoing pricing pressure, it could have a material adverse impact on our financial results.


Because we have a concentrated customer base, future sales and cash flows could be negatively impacted by the actions or loss of one or more key customers


A relatively small number of end customers accounted for a high percentage of our net sales.  This concentration subjects us to a variety of risks including:


The loss or insolvency of one or more of our key customers, could result in a substantial loss of sales and reduction in anticipated cash flows;

Customers may possess substantial leverage in negotiating contractual obligations, including liability provisions; and 

Mergers and consolidations between customers could result in further concentration of the customer base.


The following table details the number of combined customers of our segments that accounted for a large percentage of segment net sales:


    Number of combined end customers   % of total segment net sales in 2021

Display Technologies





Optical Communications





Specialty Materials





Environmental Technologies





Life Sciences








Events outside of Cornings control, or those of our contract manufacturers, could cause a disruption to our manufacturing operations and adversely impact our customers, resulting in a negative impact to Cornings net sales, net income, asset values and liquidity


Disruption to our manufacturing operations, or those of our contract manufacturers, could significantly impact Corning’s ability to supply its customers and could produce a near-term severe impact on our individual business units and the Company. Given the geographical concentration of certain of the Company's and our contract manufacturers' plants, the highly engineered nature of the facilities and the globally dispersed talent required to run these facilities, any event that adversely affects or restricts movement into or out of a specific geographic area where we, our contract manufacturers, our suppliers, or our customers have a presence, could adversely impact our results. Due to the specialized nature of our products and single-site manufacturing locations, in the event such a location experiences disruption, it we may not be possible to find replacement capacity or substitute production from other facilities. 


We may experience difficulties in enforcing our intellectual property rights, which could result in loss of market share, and we may be subject to claims of infringement of the intellectual property rights of others


We rely on patent and trade secret laws, copyright, trademark, confidentiality procedures, controls and contractual commitments to protect our intellectual property rights. Despite our efforts, these protections may be limited and we may encounter difficulties in protecting our intellectual property rights or obtaining rights to additional intellectual property necessary to permit us to continue or expand our businesses. We cannot provide assurance that the patents that we hold or may obtain will provide meaningful protection against our competitors. Changes in or enforcement of laws concerning intellectual property may affect our ability to prevent or address the misappropriation of, or the unauthorized use of, our intellectual property, potentially resulting in loss of market share. Litigation may be necessary to enforce our intellectual property rights. Litigation is inherently uncertain and outcomes are unpredictable. If we cannot protect our intellectual property rights against unauthorized copying or use, or other misappropriation, we may not remain competitive.


The intellectual property rights of others could inhibit our ability to introduce new products. Other companies hold patents on technologies used in our industries and are aggressively seeking to expand, enforce and license their patent portfolios. We periodically receive notices from, or have lawsuits filed against us by third parties claiming infringement, misappropriation or other misuse of their intellectual property rights and/or breach of our agreements with them. These third parties often include entities that do not have the capabilities to design, manufacture, or distribute products or that acquire intellectual property like patents for the sole purpose of monetizing their acquired intellectual property through asserting claims of infringement and misuse. Such claims of infringement or misappropriation may result in loss of revenue, substantial costs, or lead to monetary damages or injunctive relief against us.


Information technology dependency and cybersecurity vulnerabilities could lead to reduced revenue, liability claims, competitive or reputational harm, and result in material adverse effects on our operations and financial results


The Company is dependent on information technology systems and infrastructure (“IT systems”) owned and operated by the Company or managed by third-party service providers, suppliers and contract manufacturers. IT systems enable us to conduct, monitor and/or protect our business, operations, systems, data and other assets. In the ordinary course of our business, we and our providers collect, process, transmit and store sensitive data, including intellectual property, our proprietary information and that of our customers, suppliers and business partners, as well as personally identifiable information.  Intrusion into a supplier or contract manufacturer system not integrated with a Corning IT system could result in service disruption and/or loss of financial control.  


Our IT systems, and those of our providers, may be vulnerable to compromise or disruption due to human error or malfeasance, outdated applications, computer viruses or malware (e.g., ransomware), natural disasters, unauthorized access, cyber-attacks and other similar incidents and disruptions. Increased work-from-home, at both the Company and our providers, presents additional operational risk.  Companies that provide utilities, water, transportation, natural gas, and other resources and services across our supply chain, are critical to our manufacturing operations and are vulnerable to cyber-attacks. From time to time, both we and certain of our providers, have been subject to cyberattacks and security incidents.  We may be unable to anticipate, detect, prevent or remediate future attacks, particularly as attackers are becoming more sophisticated in their ability to circumvent controls and remove forensic evidence.




Any significant disruption, breakdown, intrusion, interruption or corruption, data breach, or compromise to the accessibility, security or integrity of our or our providers’ IT systems, or the misappropriation or disclosure of any confidential, proprietary or personally identifiable information, could result in the loss of data or intellectual property, equipment or systems damage, downtime, safety related issues and could have a material adverse effect on our business, including by harming our competitive position and reputation, disrupting our manufacturing, reducing the value of our investment in research and development and other strategic initiatives, impairing our ability to access suppliers, contract manufacturers, customers, and cloud-based services, subjecting us to litigation or regulatory investigations or fines, increasing the costs of compliance and remediation, or otherwise adversely affecting our business.  We may be required to invest significant additional resources to comply with evolving cybersecurity regulations and to modify and enhance our IT systems, information security and controls, and to investigate and remediate any security vulnerabilities. Any losses, costs or liabilities may not be covered by, or may exceed the coverage limits of, any, or all, of our applicable insurance policies. 


We may not earn a positive return from our research, development and engineering investments


Developing our products through our innovation model of research and development is costly and often involves a long investment cycle. We make significant investments in research, development and engineering that may not earn an economic return. If our investments do not provide a pipeline of products or technologies that our customers demand or lower our manufacturing costs, it could negatively impact our revenue and operating margins for both near- and long-term.


Our innovation model depends on our ability to attract and retain specialized experts in our core technologies


Our innovation model requires us to employ highly specialized experts in glass science, ceramic science, and optical physics to conduct our research and development and engineer our products and design our manufacturing facilities. The loss of the services of any member of our key research and development or engineering team without adequate replacement, or the inability to attract new qualified personnel, could have a material adverse effect on our operations and financial performance.


We are subject to strict environmental regulations and regulatory changes that could result in fines or restrictions that interrupt our operations


Some of our manufacturing processes generate chemical waste, wastewater, other industrial waste or greenhouse gases, and we are subject to numerous laws and regulations relating to the use, storage, discharge and disposal of such substances. We have installed anti-pollution equipment for the treatment of chemical waste and wastewater at our facilities. We have taken steps to control the amount of greenhouse gases created by our manufacturing operations. However, we cannot provide assurance that environmental claims will not be brought against us or that government regulators will not take steps to adopt more stringent environmental standards.


Any failure on our part to comply with any present or future environmental regulations could result in the assessment of damages or imposition of fines against us, or the suspension/cessation of production or operations. In addition, environmental regulations could require us to acquire costly equipment, incur other significant compliance expenses or limit or restrict production or operations and thus materially and negatively affect our financial condition and results of operations.


Changes in regulations and the regulatory environment in the U.S. and other countries, such as those resulting from the regulation and impact of global warming and CO2 abatement, may affect our businesses and their results in adverse ways by, among other things, substantially increasing manufacturing costs, limiting availability of scarce resources, especially energy, or requiring limitations on production and sale of our products or those of our customers.




General Risk Factors


We may have additional tax liabilities


We are subject to income taxes in the U.S. and many foreign jurisdictions, and are commonly audited by various tax authorities.  There are many transactions and calculations where the ultimate tax treatment is uncertain.  Judgment is required in determining our worldwide provision for income taxes.  Although we believe our tax estimates are reasonable, the final determination of tax, assessments, audits and any related litigation could be materially different from our historical income tax provisions and accruals, or result in the forfeiture of funds deposited with the relevant government authorities.  The results of an audit or litigation could have a material effect on our financial statements in the period or periods for which such a determination is made.  


The U.S., other countries and international organizations, such as Organisation for Economic Co-operation and Development (“OECD”), may change their laws or issue new international tax standards that may also impact our taxes. 


As a global company, we face many risks which could adversely impact our operations and financial results


We are a global company and derive a substantial portion of our revenue from, and have significant operations, outside of the U.S. Our international operations include manufacturing, assembly, sales, research and development, customer support, and shared administrative service centers. Additionally, we rely on a global supply chain for key components and capabilities that are central to our ability to invent, make and sell products.


Compliance with laws and regulations increases our costs. We are subject to both U.S. laws and the local laws where we operate which, among other things, include data privacy requirements, employment and labor laws, tax laws, anti-competition regulations, prohibitions on payments to governmental officials, import and trade restrictions and export requirements. Non-compliance or violations could result in fines, criminal sanctions against us, our officers or employees, and prohibitions on the conduct of our business. Such violations could result in prohibitions on our ability to offer our products and services in one or more countries and could also materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, our businesses and operating results. Our success depends, in part, on our ability to anticipate and manage these risks.


Corning is exposed to risks associated with an uncertain and inflationary global economy


Uncertain or adverse economic and business conditions, including uncertainties and volatility in the financial markets, national debt, fiscal or monetary concerns, inflation and rising interest rates in various regions, could materially adversely impact Corning’s operating results. Markets for our products depend largely on business and consumer spending and demand for network capacity, electronics and automotive products. Uncertain or adverse economic and business conditions that result in decreases in consumer spending and demand, or cause us to pass on increased costs to our customers, may cause certain of our customers to push out, cancel or refrain from purchasing our products, which could materially adversely impact demand for our products and our operating results. In addition, the COVID-19 pandemic, and transportation interruptions and other measures taken in response thereto, have had, and may continue to have, a significant adverse impact on the global and regional economic activity, as well as our ability to meet our customer demand.


Similarly, changes that result in sudden increases in consumer demand for electronic products have resulted in, and may continue to result in, a shortage of parts and materials needed to manufacture our products or the products in which our products are used. Such shortages, as well as shipment delays due to transportation interruptions, have adversely impacted, and may continue to adversely impact, our ability to meet our demand requirements.


Uncertain economic and industry conditions also make it more challenging for Corning to forecast its operating results, make business decisions, and identify and prioritize the risks that may affect its businesses, sources and uses of cash, financial condition and results of operations. If Corning does not appropriately manage its business operations in response to changing economic and industry conditions, it could have a significant negative impact on its business performance and financial condition. Even during periods of economic uncertainty or lower revenues, Corning must continue to invest in research and development and maintain a global business infrastructure to compete effectively and support its customers, which can have a negative impact on its operating margins and earnings.




We are also subject to a variety of other risks in managing a global organization, including those related to:


The economic and political conditions in each country or region and among countries;

Complex regulatory requirements affecting international trade and investment, including anti-dumping laws, export controls, the Foreign Corrupt Practices Act and local laws prohibiting improper payments. Our operations may be adversely affected by changes in the substance or enforcement of these regulatory requirements, and by actual or alleged violations of them;

Fluctuations in currency exchange rates, convertibility of currencies and restrictions involving the movement of funds between jurisdictions and countries;

Governmental protectionist policies and sovereign and political risks that may adversely affect Corning’s profitability and assets;

Tariffs, trade duties and other trade barriers including anti-dumping duties;

Geographical concentration of our factories and operations, and regional shifts in our customer base;

Periodic health epidemic or pandemic concerns, such as COVID-19;

Political unrest, geopolitical tensions, confiscation or expropriation of assets by foreign governments, terrorism and the potential for other hostilities;

Difficulty in protecting intellectual property, sensitive commercial and operations data, and information technology systems;

Differing legal systems, including protection and treatment of intellectual property and patents;

Complex, changing or competing tax regimes;

Difficulty in collecting obligations owed to us;

Natural disasters such as floods, earthquakes, tsunamis and windstorms; and

Potential loss of utilities or other disruption affecting manufacturing.


We have significant exposure to foreign currency movements


A large portion of our sales, profit and cash flows are transacted in non-U.S. dollar currencies. The Company expects to continue to experience fluctuations in the U.S. dollar value of these activities if it is not possible, cost-effective or should we not elect to hedge certain currency exposure.  Additionally, gains or losses may be experienced if the underlying exposure which has been hedged increases or decreases significantly.


The ultimate realized gain or loss with respect to currency fluctuations will generally depend on the size and type of cross-currency exposure that we have, the changes in exchange rates associated with those exposures, whether we have entered into foreign currency contracts to offset these exposures and other factors. 


These factors, which are variable and generally outside of our control, could materially impact our results of operations, anticipated future results, financial position and cash flows.


We may have significant exposure to counterparties of our related derivatives portfolio


We maintain a significant portfolio of over the counter derivatives to hedge our projected currency exposure.  We are exposed to potential losses in the event of non-performance by our counterparties to these derivative contracts. Any failure of a counterparty to pay on such a contract when due could materially impact our results of operations, financial position, and cash flows.


Current or future litigation or regulatory investigations may harm our financial condition or results of operations


As a global technology and manufacturing company, we are engaged in various litigation and regulatory matters. Litigation and regulatory proceedings may be uncertain, and adverse rulings could occur, resulting in significant liabilities, penalties or damages. Any such substantial legal liability or regulatory action could have a material adverse effect on our business, financial condition, cash flows and reputation.




Our business is subject to various governmental regulations, and compliance with these regulations may cause us to incur significant expense. If we fail to maintain compliance with applicable regulations, we may be forced to cease the manufacture and distribution of certain products, and we could be subject to administrative proceedings and civil or criminal penalties


Our products and operations are also subject to regulation by U.S. and non‐U.S. regulatory agencies, such as the U.S. Federal Trade Commission (“FTC”). From time to time, we may also be involved or required to participate in regulatory investigations or inquiries, into certain of our contracting and business practices, which may evolve into legal or other administrative proceedings. Growing public concern over concentration of economic power in corporations is likely to result in increased anti‐competition legislation, regulation, administrative rule making, and enforcement activity. Involvement in regulatory investigations or inquiries, can be costly, lengthy, complex and time consuming, diverting the attention and energies of our management and technical personnel.  If any pending or future governmental investigations result in an unfavorable resolution, we could be required to cease the manufacture and sale of the subject products or technology, pay fines or disgorge profits or other payments, and/or cease certain conduct and/or modify our contracting or business practices, which could have a material adverse effect on our business, financial condition and results of operations. We may be obligated to indemnify our current or former directors or employees, or former directors or employees of companies that we have acquired, in connection with regulatory investigations. These liabilities could be substantial and may include, among other things, the cost of government, law enforcement or regulatory investigations and civil or criminal fines and penalties.


Our global operations are subject to extensive trade and anti-corruption laws and regulations


Due to the international scope of our operations, we are subject to a complex system of import- and export-related laws and regulations, including U.S. regulations issued by Customs and Border Protection, the Bureau of Industry and Security, the Office of Anti-boycott Compliance, the Directorate of Defense Trade Controls and the Office of Foreign Assets Control, as well as the counterparts of these agencies in other countries. Any alleged or actual violation by an employee or the Company may subject us to government scrutiny, investigation and civil and criminal penalties, and may limit our ability to import or export our products or to provide services outside the U.S. We cannot predict the nature, scope or effect of future regulatory requirements to which our operations might be subject to, based on the way existing laws might be administered or interpreted.


In addition, the U.S. Foreign Corrupt Practices Act and similar foreign anti-corruption laws generally prohibit companies and their intermediaries from making improper payments or providing anything of value to improperly influence foreign government officials to obtain or retain business, or obtaining an unfair advantage. Recent years have seen a substantial increase in the global enforcement of anti-corruption laws. Our continued operation and expansion outside the U.S., including in developing countries, could increase the risk of alleged violations. Violations of these laws may result in severe criminal or civil sanctions, could disrupt our business, and result in an adverse effect on our reputation, business and results of operations or financial condition.


Moreover, several of our key customers are domiciled in areas of the world with laws, rules and business practices that may notably differ from those in the U.S., and we face the reputational and legal risk that our related partners may violate applicable laws, rules and business practices.


International trade policies may negatively impact our ability to sell and manufacture our products outside of the U.S.


Government policies on international trade and investment such as import quotas, tariffs, and capital controls, whether adopted by individual governments or addressed by regional trade blocs, can affect the demand for our products and services, impact the competitive position of our products or prevent us, our equity affiliates or joint ventures, from being able to sell and manufacture products in certain countries. The implementation of more restrictive trade policies, such as higher tariffs or new barriers to entry, together with anti-dumping claims, duties, slowed regulatory approvals and other restrictions, in countries in which we import raw materials and components or sell large quantities of products and services could negatively impact our business, results of operations and financial condition. For example, a government’s adoption of “buy national” policies or retaliation by another government against such policies could have a negative impact on our results of operations.

Total assets and capital expenditures by operating segment are included in Note 20 (Reportable Segments) to the consolidated financial statements. Information concerning lease commitments is included in Note 7 (Leases) and Note 14 (Commitments, Contingencies and Guarantees) to the consolidated financial statements.


Item 3. Legal Proceedings


Corning is a defendant in various lawsuits and is subject to various claims that arise in the normal course of business, the most significant of which are summarized in Note 14 (Commitments, Contingencies and Guarantees) to the consolidated financial statements. In the opinion of management, the likelihood that the ultimate disposition of these matters will have a material adverse effect on Corning’s consolidated financial position, liquidity, or results of operations, is remote.  


Environmental Litigation


Corning has been named by the Environmental Protection Agency (the Agency) under the Superfund Act, or by state governments under similar state laws, as a potentially responsible party for 15 active hazardous waste sites. Under the Superfund Act, all parties who may have contributed any waste to a hazardous waste site, identified by the Agency, are jointly and severally liable for the cost of cleanup unless the Agency agrees otherwise. It is Corning’s policy to accrue for its estimated liability related to Superfund sites and other environmental liabilities related to property owned by Corning based on expert analysis and continual monitoring by both internal and external consultants. At December 31, 2021 and 2020, Corning had accrued approximately $55 million (undiscounted) and $68 million (undiscounted), respectively, for the estimated liability for environmental cleanup and related litigation. Based upon the information developed to date, management believes that the accrued reserve is a reasonable estimate of the Company’s liability and that the risk of an additional loss in an amount materially higher than that accrued is remote.

Forward-Looking Statements




In response to the COVID-19 pandemic ("the pandemic") and the ensuing economic uncertainty, including changing market conditions, the Company has and will continue to focus on three core priorities: protecting employees and communities; delivering on customer commitments and preserving the financial health of the Company.  We are continuing to build a stronger, more resilient company that is committed to rewarding shareholders and supporting all global stakeholders.


Despite the pandemic and resulting global disruptions, Corning adapted rapidly and remained resilient. We acted quickly to preserve our financial strength by executing well and advancing major innovations with industry leaders. We have continued to effectively leverage our focused and cohesive portfolio to create value and outperform our underlying markets, contributing to sales and earnings growth and strong free cash flow in the second half of 2020 and full year 2021.


Corning announced the Strategy & Growth Framework in 2019, highlighting significant opportunities to sell more Corning content through each of our Market-Access Platforms.  The Company is focused on our cohesive portfolio and the utilization of our financial strength, supported by strong operating cash flow generation, which we expect to continue.  Corning has and will continue to use its cash to grow, extend its leadership and reward shareholders.  Our key growth drivers remain intact, and some are accelerating as key trends converge around Corning’s capabilities. 


Corning will continue to advance the objectives of the Strategy & Growth Framework, which sets its leadership priorities and articulates opportunities across its businesses.  Our probability of success increases as we invest in our world-class capabilities.  Corning is concentrating approximately 80% of its research, development and engineering investment along with capital spending on a cohesive set of three core technologies, four manufacturing and engineering platforms, and five Market-Access Platforms.  This strategy allows us to quickly apply our talents and repurpose our assets across the Company, as needed, to capture high-return opportunities.




2021 Results


Net sales in the year ended December 31, 2021 were $14.1 billion, a net increase of $2.8 billion, or 25%, when compared to the year ended December 31, 2020, driven by higher sales for all segments.


For the year ended December 31, 2021, we generated net income of $1,906 million, or $1.28 per diluted share, compared to a net income of $512 million, or $0.54 per diluted share, for 2020. When compared to 2020, the $1.4 billion increase in net income was primarily due to the following items (amounts presented after tax):


Higher net income of $505 million for reportable segments;
Lower restructuring, impairment and other charges of $543 million;
The positive impact of mark-to-market translated earnings contract gains of $309 million;

Higher translation gains on Japanese yen-denominated debt of $205 million; and

Lower net losses of $163 million for "All Other" primarily driven by full-year consolidation of HSG.


The increases in net income, outlined above, were partially offset by the absence of a gain on a previously held equity investment in HSG of $387 million in 2020.


Diluted earnings per share increased in 2021 by $0.74 per diluted share, or 137%, when compared to 2020, primarily driven by the increase in net income, described above, partially offset by the immediate repurchase and retirement of 35 million Common Shares which resulted in an $803 million one-time reduction to net income available to common shareholders during the second quarter of 2021.  Refer to Note 17 (Shareholders' Equity) and Note 18 (Earnings per Common Share) to the consolidated financial statements for additional information.


The translation impact of fluctuations in foreign currency exchange rates, including the impact of hedges realized in the current year, positively impacted Corning’s net income by approximately $104 million in the year ended December 31, 2021, when compared to the same period in 2020.


2022 Corporate Outlook


We believe 2022 will be another year of growth and strong cash-flow generation. We expect full year net sales of approximately $15 billion in 2022.

The adjustment was associated with a previously recorded commercial benefit asset, reflected as a prepayment, to a customer with a long-term supply agreement that substantially exited its production of LCD panels.


*    Percent change not meaningful.


For the year ended December 31, 2021, segment and "All Other" net sales increased by $2.7 billion, or 23%, when compared to the same period in 2020. The primary sales drivers by segment were as follows:


Display Technologies’ net sales increased by $528 million, primarily driven by volume increases of approximately mid-teens in percentage terms and pricing consistent with 2020;

Optical Communications’ net sales increased $786 million, as sales increased for carrier products by $588 million and enterprise products by $198 million, primarily driven by strong growth of 5G, broadband and cloud computing;

Net sales for Environmental Technologies increased $216 million, primarily due to increased sales of heavy-duty diesel products and gas-particulate filters;

Net sales in the Life Sciences segment increased by $236 million, primarily driven by ongoing increased demand to support the global pandemic response, continued recovery in research labs, and strong demand for bioproduction vessels and diagnostic-related consumables.;

Net sales increased in the Specialty Materials segment in the amount of $124 million, primarily driven by strong demand for premium cover materials and advanced optics content used in semiconductor manufacturing; and

Net sales for “All Other” increased by $778 million, primarily driven by full-year consolidation of HSG.


Movements in foreign exchange rates positively impacted Corning’s consolidated net sales by $83 million in the year ended December 31, 2021, when compared to the same period in 2020.


In 2021 and 2020, sales in international markets accounted for 68% and 70% of total net sales, respectively.


Cost of Sales


The types of expenses included in the cost of sales line item are: raw materials consumption, including direct and indirect materials; salaries, wages and benefits; depreciation and amortization; production utilities; production-related purchasing; warehousing (including receiving and inspection); repairs and maintenance; inter-location inventory transfer costs; production and warehousing facility property insurance; rent for production facilities; and other production overhead.




Gross Margin


In the year ended December 31, 2021, gross margin increased by $1,532 million, or 43%. Gross margin as a percentage of sales increased by 5 percentage points.  The increase in gross margin was primarily driven by higher sales in all segments, as well as lower charges for severance and capacity realignment costs of $89 million and $252 million, respectively, partially offset by increased expenses due to elevated freight, logistics and raw material costs for the year ended December 31, 2021.


Movements in foreign exchange rates had a positive impact of $77 million on Corning’s consolidated gross margin in the year ended December 31, 2021, when compared to the same period in 2020.


Selling, General and Administrative Expenses


When compared to the year ended December 31, 2020, selling, general and administrative expenses increased by $80 million, or 5%, in the year ended December 31, 2021.  The increase was primarily driven by higher litigation and share-based compensation costs.  Selling, general and administrative expenses decreased by 2 percentage points as a percentage of sales.


The types of expenses included in the selling, general and administrative expenses line item are: salaries, wages and benefits; stock-based compensation expense; travel; sales commissions; professional fees; and depreciation and amortization, utilities and rent for administrative facilities.


Research, Development and Engineering Expenses


For the year ended December 31, 2021, research, development and engineering expenses decreased by $159 million, or 14%, when compared to the same period in the prior year, primarily driven by the absence of a pre-tax asset impairment loss of $211 million related to the reassessment and reprioritization of research and development programs within “All Other” that was incurred in 2020.  As a percentage of sales, these expenses were 3 percentage points lower when compared to the same period last year.


Translated earnings contract gain (loss), net


Included in the line item translated earnings contract gain (loss), net, is the impact of foreign currency contracts which hedge our translation exposure arising from movements in the Japanese yen, South Korean won, new Taiwan dollar, euro, Chinese yuan and British pound and its impact on our net income.

Includes pre-tax realized losses related to the expiration of option contracts for the year ended December 31, 2021, 2020, and 2019 of $20 million, $20 million and $37 million, respectively.  These amounts were reflected in operating activities in the consolidated statements of cash flows.


The impact to income was primarily driven by Japanese yen, South Korean won, and euro-denominated hedges of translated earnings.




Income Before Income Taxes


The translation impact of fluctuations in foreign currency exchange rates, including the impact of hedges realized in the current year, positively impacted Corning’s income before income taxes by $134 million in the year ended December 31, 2021, when compared to the same period in 2020.


Provision for Income Taxes 


Our provision for income taxes and the related effective income tax rates were as follows (in millions):



Year ended December 31,








Provision for income taxes

    $ (491 )   $ (111 )   $ (256 )

Effective tax rate

      20.5 %     17.8 %     21.1 %


For the year ended December 31, 2021, the effective income tax rate differed from the U.S. statutory rate of 21% primarily due to the following:


A net provision of $52 million due to differences arising from foreign earnings, including the impact of intercompany asset sales;

A net benefit of $37 million related to share-based compensation payments; and

A net benefit of $62 million due to tax credits.


For the year ended December 31, 2020, the effective income tax rate differed from the U.S. statutory rate of 21% primarily due to the following:


Additional net provision of $73 million from changes to our tax reserves;

A net provision of $45 million due primarily to stronger foreign earnings relative to U.S. earnings in the current year, as well as U.S. income inclusion under the Internal Revenue Code (“Subpart F income”); and

A net benefit of $116 million due to a net operating loss carryback allowed under the CARES Act.


During 2021, the Company distributed approximately $2.3 billion from foreign subsidiaries to their respective U.S. parent companies.  As of December 31, 2021, Corning has approximately $2.4 billion of indefinitely reinvested foreign earnings.  It remains impracticable to calculate the tax cost of repatriating our unremitted earnings which are considered indefinitely reinvested. 


Refer to Note 8 (Income Taxes) to the consolidated financial statements for further details regarding income tax matters.

For the year ended December 31, 2021, comprehensive income increased by $528 million, when compared to the same period in 2020, primarily due to the following:


An increase in net income of $1.4 billion; and 
The positive change of $266 million of unamortized gains (losses) and prior service credits (costs) for postretirement benefit plans.


This gain was partially offset by the following:


The unfavorable change in foreign currency translation adjustments of $1.1 billion, largely driven by the Japanese yen, South Korean won and Chinese yuan.


Refer to Note 13 (Employee Retirement Plans) and Note 17 (Shareholders’ Equity) to the consolidated financial statements for additional details.







In managing the Company and assessing our financial performance, we adjust certain measures provided by our consolidated financial statements to exclude specific items to report core performance measures. These items include gains and losses on our translated earnings contracts, acquisition-related costs, certain discrete tax items and other tax-related adjustments, restructuring, impairment losses, and other charges and credits, certain litigation-related expenses, pension mark-to-market adjustments and other items which do not reflect on-going operating results of the Company or our equity affiliates. Corning utilizes constant-currency reporting for our Display Technologies, Environmental Technologies, Specialty Materials and Life Sciences segments for the Japanese yen, South Korean won, Chinese yuan, new Taiwan dollar and the euro.  The Company believes that the use of constant-currency reporting allows investors to understand our results without the volatility of currency fluctuations and reflects the underlying economics of the translated earnings contracts used to mitigate the impact of changes in currency exchange rates on our earnings and cash flows. Corning also believes that reporting core performance measures provides investors greater transparency to the information used by our management team to make financial and operational decisions.


Core performance measures are not prepared in accordance with Generally Accepted Accounting Principles in the U.S. (“GAAP”). We believe investors should consider these non-GAAP measures in evaluating our results as they are more indicative of our core operating performance and how management evaluates our operational results and trends. These measures are not, and should not be viewed as a substitute for, GAAP reporting measures. With respect to the Company’s outlook for future periods, it is not possible to provide reconciliations for these non-GAAP measures because the Company does not forecast the movement of foreign currencies against the U.S. dollar, or other items that do not reflect ongoing operations, nor does it forecast items that 

have not yet occurred or are out of the Company’s control. As a result, the Company is unable to provide outlook information on a GAAP basis.


For a reconciliation of non-GAAP performance measures to their most directly comparable GAAP financial measure, please see “Reconciliation of Non-GAAP Measures”.
