ITEM 1A. RISK FACTORS
Item 1A. Risk Factors
We operate globally in a rapidly changing economic, political and technological environment that presents 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
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, among other factors, 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 our prices 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 thereby also negatively impact our operating results, future profitability and ability to successfully deliver on our strategy.
Factors such as 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, utilities and other essentials required in our products or processes, our business will be negatively impacted
Corning’s business relies on the timely supply of raw materials, precious metals, natural resources or utilities including energy and industrial water, equipment, parts and components, 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 or 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 are available only from a single supplier or limited group of suppliers and we may not be able to find alternate sources in a timely manner. 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, scale back or cease operations, which could impact our ability to meet customer demand and 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, labor strife or capacity constraints;
•A worldwide shortage of semiconductor components or other issues;
•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 crisis events, 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.
Health crisis events, such as epidemics or pandemics, have adversely impacted, and may continue to impact, the economy and disrupt our operations and supply chains, which may have an adverse effect on our results of operations
Health crisis events, including epidemics or pandemics, such as COVID-19, have impacted and may further impact the economy and could have additional impacts on economic growth, supply chains, the proper functioning of financial and capital markets, foreign currency exchange rates and interest rates. Recently, the COVID-19 pandemic 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 our workforce, operations and supply chains, and those of our customers, contract manufacturers and suppliers, and may continue to have an impact particularly in the event of another significant global health crisis. There is considerable uncertainty regarding the duration, scope and severity of a health crisis event and the impacts on our business and the economy from the effects of such an event and response measures.
Corning’s Display Technologies segment generates a significant amount of the Company’s profits and cash flow; any significant decrease in display glass pricing, volume or market share could have a material and negative impact on our financial results
Corning’s ability to generate profits and operating cash flow could be significantly impacted by the profitability of our display glass business, which is subject to pricing pressure, exchange rate movements, industry competition, potential over-capacity, development of new technologies and operational and regulatory risks. If we are not able to achieve proportionate reductions in costs and/or increases in volume or price to offset the aforementioned factors, 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 account for a high percentage of our net sales in each of our business segments. 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 reportable segments that accounted for a large percentage of segment net sales, not adjusted for constant currency:
Number of combined end customers % of total segment net sales in 2024
Optical Communications 2 27 %
Display Technologies 4 67 %
Specialty Materials 2 43 %
Environmental Technologies 3 71 %
Life Sciences 2 42 %
Events outside of Corning’s control, or those of our contract manufacturers, could cause a disruption to our manufacturing operations and our ability to serve our customers, resulting in a negative impact to Corning’s 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 in Asia Pacific, 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, suppliers, or 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 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 decreased sales and profits, 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 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 entities that acquire intellectual property, including 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. Inadequate account security or organizational security practices may also result in unauthorized access. 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. Our security processes and initiatives may not be capable of anticipating, detecting, preventing or remediating all attacks, particularly as attackers are becoming more sophisticated in their ability to circumvent controls and remove forensic evidence. The rapid development and increasing adoption of emerging technologies, such as artificial intelligence and machine learning, may further complicate our ability to anticipate and implement effective protective measures against cyber events.
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, or if our products or technologies become obsolete or disrupted by emerging technologies, 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 expertise
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 and reduce 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 the many other countries in which we operate, such as those resulting from the regulation and impact of climate change, CO2 abatement and emission reduction targets, may affect our businesses and results in adverse ways by, among other things, substantially increasing manufacturing costs, limiting availability of scarce resources, especially energy, or requiring limitations on production or sales 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, 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 multiple legal and regulatory requirements 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 a global economy, including government fiscal and monetary policies
Uncertain or adverse economic and business conditions, including uncertainties and volatility in the financial markets, national debt, fiscal or monetary concerns, availability of government incentives, 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 recessionary business conditions, among other factors, that could 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.
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 relationships 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;
•Adverse changes relating to government grants, tax credits or other government incentives;
•Tariffs, trade duties and other trade barriers including anti-dumping and countervailing duties;
•Geographical concentration of our factories and operations, and regional shifts in our customer base;
•Health crisis events, including epidemic or pandemic concerns;
•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 disruptions 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, primarily the Japanese yen, South Korean won, New Taiwan dollar, Mexican peso, Chinese yuan and euro. 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 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. 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 obtain 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 country’s adoption of nationalistic policies or retaliation by another government against such policies could have a negative impact on our results of operations. Further, these actions in conjunction with any trade tensions may restrict us from participating in a specific market or may prevent us from competing effectively.

ITEM 3. LEGAL PROCEEDINGS
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 12 (Commitments, Contingencies and Guarantees) in the accompanying notes 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 the Company’s consolidated financial position, liquidity, or results of operations, is remote.
Environmental Litigation
Corning has been designated by federal or state governments under environmental laws, including Superfund, as a potentially responsible party that may be liable for cleanup costs associated with 20 hazardous waste sites. It is Corning’s policy to accrue for its estimated liability related to such hazardous waste sites and other environmental liabilities related to property owned by Corning based on expert analysis and continual monitoring by both internal and external consultants. As of December 31, 2024 and 2023, Corning had accrued approximately $78 million and $88 million, respectively, for the estimated undiscounted 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.

OVERVIEW
Corning is vital to progress - in the industries we help advance and in the world we share. For more than 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. Our materials science and manufacturing expertise, boundless curiosity and commitment to purposeful invention place us at the center of the way the world works, learns and lives. In addition, our sustained investment in research, development and engineering capabilities means we are always ready to solve the toughest challenges - alongside our customers.
Our capabilities are versatile and synergistic, allowing Corning to evolve to meet changing market needs, while also helping customers capture new opportunities in dynamic industries. Corning strives to be a catalyst for positive change and to help move the world forward. The Company drives profitable multiyear growth by inventing, making and selling life-changing products - all of which is based on a set of vital capabilities that are increasingly relevant to profound transformations that touch many facets of daily life. Today, Corning's markets include optical communications, mobile consumer electronics, display, automotive, solar, semiconductor and life sciences.
Going into 2024, we introduced our three-year Springboard plan to add more than $3 billion in annualized sales by the end of 2026. As we capture this growth, we expect to deliver powerful incrementals because we already have the required production capacity and technical capabilities in place, and the cost and capital are already reflected in our financials. Additionally, we expect to achieve an operating margin target of 20% by the end of 2026.
In 2024, we began marking important milestones toward our Springboard plan - including the implementation of price increases in Display Technologies and growth in Optical Communications driven by increased demand for our new Generative AI products. And in the fourth quarter of 2024 compared to 2023 we grew quarterly sales while growing profit significantly faster, resulting in a strong close to the first year of Springboard.
Overall, we expect our businesses to benefit from a convergence of cyclical and secular trends, driving sales and profit growth across the company through 2026, and we are energized about the tremendous value Springboard creates for shareholders.
2025 Corporate Outlook
We expect core net sales of approximately $3.6 billion for the first quarter of 2025.

Net Sales
Net sales for the year ended December 31, 2024 increased by $530 million, or 4%, when compared to the same period in 2023. The increase was primarily driven by an increase in sales for telecommunication products of $645 million and specialty glass products of $146 million, partially offset by a decrease in sales for polycrystalline silicon products of $149 million and environmental substrate and filter products of $95 million. Refer to the “Segment Analysis” section of our MD&A below for a discussion of net sales by segment.
In 2024 and 2023, sales in international markets accounted for 64% and 67% of total net sales, respectively.
Cost of Sales / Gross Margin
The types of expenses included in cost of sales 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; freight and logistics costs; and other production overhead.
Gross margin increased by $345 million, or 9% and gross margin as a percentage of net sales increased by 2 percentage points when compared to 2023. The increase in gross margin is primarily driven by the increase in net sales, as discussed above. Since 2023, actions were taken by management to improve profitability, including raising prices, restoring our productivity levels and normalizing inventory levels, which has resulted in improvements in gross margin as a percentage of net sales.
Selling, General and Administrative Expenses
The types of expenses included in selling, general and administrative expenses are: salaries, wages and benefits, including variable compensation and share-based compensation expense; travel; sales commissions; professional fees; and depreciation and amortization, utilities and rent for administrative facilities.
Selling, general and administrative expenses increased by $88 million, or 5%, when compared to 2023 primarily due to the increase in net sales, as discussed above, and remained consistent as a percentage of net sales.
Research, Development and Engineering Expenses
Research, development and engineering expenses increased by $13 million, or 1%, and decreased as a percentage of net sales by 1 percentage point when compared to 2023.
Translated earnings contract gain, net
Included in translated earnings contract gain, net, is the impact of foreign currency contracts which economically hedge the translation exposure arising from movements in the Japanese yen, South Korean won, New Taiwan dollar, euro, Chinese yuan, Mexican peso and British pound and its impact on net income.
The following table provides detailed information on the impact of translated earnings contract gain, net (in millions):
Income before tax Net income Income before tax Net income Income before tax Net income
2024 vs. 2023
Hedges related to translated earnings:
Realized gain, net (1) (2)
$ 194 $ 149 $ 247 $ 198 $ (53) $ (49)
Unrealized loss, net
(111) (85) (86) (68) (25) (17)
Total translated earnings contract gain, net $ 83 $ 64 $ 161 $ 130 $ (78) $ (66)
(1)For the years ended December 31, 2024 and 2023, amount includes non-cash pre-tax realized losses of $85 million and $68 million, respectively, related to the premiums of expired option contracts.
(2)For the year ended December 31, 2023, amount excludes an $11 million gain related to a forward contract designated as a net investment hedge, which was reflected within investing activities in the consolidated statements of cash flows.
The impact to income from realized activity for the year ended December 31, 2024 was primarily driven by realized gains from our Japanese yen-denominated hedges, partially offset by realized losses from our South Korean won, Chinese yuan, new Taiwan dollar and Mexican peso-denominated hedges. The impact to income for the year ended December 31, 2023 was primarily driven by realized gains from our Japanese yen-denominated hedges, partially offset by realized losses from our South Korean won and Chinese yuan-denominated hedges.
The impact to income from unrealized activity for the year ended December 31, 2024 was primarily driven by unrealized losses from our South Korean won, Japanese yen, new Taiwan dollar and Chinese yuan-denominated hedges, partially offset by unrealized gains from our euro-denominated hedges. The impact to income for the year ended December 31, 2023 was primarily driven by unrealized losses from our Japanese Yen, South Korean won and euro-denominated hedges.
Income before income taxes
Income before income taxes remained flat for the year ended December 31, 2024 as compared to 2023, driven by an increase in operating income of $245 million as a result of the increase in net sales and cost of sales, as discussed above, partially offset by the increase in selling, general and administrative expenses, as discussed above. The improved operating income for the year ended December 31, 2024 as compared to 2023 is offset by increases of non-operating expenses of $248 million, primarily due to the recognition of $145 million of non-cash cumulative foreign currency translation losses in 2024 related to the substantial liquidation and disposition of foreign entities, which was recorded in other (expense) income, net in the consolidated statements of income, and $49 million of non-cash charges recognized in 2024 in one of our Emerging Growth Businesses relating to a customer that recently entered into a multi-jurisdictional restructuring effort including insolvency filings in certain countries. These charges primarily relate to the full write-down of upfront payments made to the customer, which were determined to be nonrecoverable, and recorded as a charge to net sales in the consolidated statements of income.
Provision for Income Taxes
For the year ended December 31, 2024, the effective tax rate differed from the U.S. statutory rate of 21% primarily due to non-deductible items, including the release of cumulative translation losses and changes in tax reserves, partially offset by non-taxable items, tax credits generated, foreign derived intangible income and changes in valuation allowance assessments.
For the year ended December 31, 2023, the effective tax rate differed from the U.S. statutory rate of 21% primarily due to tax credits generated, non-taxable items, foreign derived intangible income and stock compensation windfall deductions, partially offset by changes in valuation allowance assessments, non-deductible items and tax reserves.
The effective tax rate for the year ended December 31, 2024 increased compared to the year ended December 31, 2023 primarily due to the release of cumulative translation losses, non-deductible items and tax credits generated, partially offset by changes in valuation allowance assessments.
Refer to Note 6 (Income Taxes) in the accompanying notes to the consolidated financial statements for further details regarding income tax matters.
The U.S. enacted the Inflation Reduction Act of 2022 (“IRA”) in August 2022, which, among other sections, creates a new book minimum tax of at least 15% of consolidated pre-tax income for corporations with average book income in excess of $1 billion. The IRA also provides credit incentives to taxpayers based on the type and amount of manufacturing activity performed. None of the provisions within the IRA are expected to have a material impact on our results of operations, financial position or cash flow.
In December 2022, the European Union (“EU”) Member States formally adopted the EU Pillar Two Framework (“Pillar Two Framework”), which generally provides for a 15% global minimum effective tax rate, based on the Organization for Economic Cooperation and Development guidelines. Certain countries have enacted this tax law change, with an effective date starting January 1, 2024 and January 1, 2025, for certain aspects of the directive. The impact of the Pillar Two Framework is not material to our results of operations, financial position or cash flow as of and for the year ended December 31, 2024.
SEGMENT ANALYSIS
Financial results for the reportable segments and Hemlock and Emerging Growth Businesses are prepared on a basis consistent with the internal disaggregation of financial information to assist the chief operating decision maker (“CODM”) in making internal operating decisions, which is more fully discussed within Note 17 (Reportable Segments) in the accompanying notes to the consolidated financial statements and includes a reconciliation of our segment information to the corresponding amounts in our consolidated statements of income.

CORE PERFORMANCE MEASURES
In managing the Company and assessing our financial performance, we adjust certain measures included in our consolidated financial statements to exclude specific items to arrive at our core performance measures. These items include the impact of translating the Japanese yen-denominated debt, the impact of the translated earnings contracts, acquisition-related costs, certain discrete tax items and other tax-related adjustments, restructuring, impairment and other charges and credits, certain litigation, regulatory and other legal matters, pension mark-to-market adjustments and other items which do not reflect the ongoing operating results of the Company.
In addition, because a significant portion of our revenues and expenses are denominated in currencies other than the U.S. dollar, management believes it is important to understand the impact on sales and net income of translating these currencies into U.S. dollars. Therefore, management utilizes constant-currency reporting for the Display Technologies, Specialty Materials, Environmental Technologies and Life Sciences segments to exclude the impact from the Japanese yen, South Korean won, Chinese yuan, New Taiwan dollar and euro, as applicable to the segment. In addition, effective January 1, 2024, the Company began utilizing constant-currency reporting for the Optical Communications segment to exclude the impact from the Mexican peso on segment results. Prior periods were not recast as the impact was not material. The most significant constant-currency adjustment relates to the Japanese yen exposure within the Display Technologies segment. The constant-currency rates established for our core performance measures are internally derived long-term management estimates, which are closely aligned with our hedging instrument rates. These hedging instruments may include, but are not limited to, foreign exchange forward or option contracts and foreign-denominated debt. For details of the rates used, refer to the footnotes to the “Reconciliation of Non-GAAP Measures” section.
We believe that the use of constant-currency reporting allows management to understand our results without the volatility of currency fluctuations, analyze underlying trends in the businesses and establish operational goals and forecasts.
Core performance measures are not prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). We provide investors with these non-GAAP measures to evaluate our results as we believe they are indicative of our core operating performance and provide greater transparency to how management evaluates our results and trends and makes financial and operational decisions. These measures are not, and should not be viewed as a substitute for, GAAP reporting measures. With respect to the outlook for future periods, it is not possible to provide reconciliations for these non-GAAP measures because management 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 management’s control. As a result, management 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, refer to “Reconciliation of Non-GAAP Measures.”

RECONCILIATION OF NON-GAAP MEASURES
We utilize certain financial measures and key performance indicators that are not calculated in accordance with GAAP to assess our financial and operating performance. A non-GAAP financial measure is defined as a numerical measure of a company’s financial performance that (i) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the comparable measure calculated and presented in accordance with GAAP in the consolidated statements of income or statements of cash flows, or (ii) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the comparable measure as calculated and presented in accordance with GAAP in the consolidated statements of income or statements of cash flows.
Core net sales, core net income and core earnings per share are non-GAAP financial measures utilized by our management to analyze financial performance without the impact of items that are driven by general economic conditions and events that do not reflect the underlying fundamentals and trends in our operations.
Refer to “Items Adjusted from GAAP Measures” for the descriptions of the footnoted reconciling items.

Refer to “Items Adjusted from GAAP Measures” for the descriptions of the footnoted reconciling items.
Items Adjusted from GAAP Measures
Items adjusted from GAAP measures to arrive at core performance measures are as follows:
(1)Constant-currency adjustment: As a significant portion of revenues and expenses are denominated in currencies other than the U.S. dollar, management believes it is important to understand the impact on sales and net income of translating these currencies into U.S. dollars. The Company utilizes constant-currency reporting for Display Technologies, Specialty Materials, Environmental Technologies and Life Sciences segments for the Japanese yen, Korean won, Chinese yuan, New Taiwan dollar and euro, as applicable to the segment. In addition, effective January 1, 2024, the Company began utilizing constant-currency reporting for the Optical Communications segment to exclude the impact from the Mexican peso on segment results. Prior periods were not recast as the impact was not material.
The constant-currency rates established for our core performance measures are internally derived long-term management estimates, which are closely aligned with our hedging instrument rates. These hedging instruments may include, but are not limited to, foreign exchange forward or option contracts and foreign-denominated debt. For the year ended December 31, 2024, the adjustment primarily relates to our Japanese yen exposure due to the difference in the average spot rate compared to our core rate.
We believe that the use of constant-currency reporting allows management to understand our results without the volatility of currency fluctuation, analyze underlying trends in the businesses and establish operational goals and forecasts.
Constant-currency rates used are as follows and are applied to all periods presented and to all foreign exchange exposures during the period, with the exception of the Mexican peso as discussed above, even though we may be less than 100% hedged:
Currency Japanese yen Korean won Chinese yuan New Taiwan dollar Euro Mexican peso
Rate ¥107 ₩1,175 ¥6.7 NT$31 €0.81 MX$20
(2)Translation of Japanese yen-denominated debt: Amount reflects the gain or loss on the translation of our yen-denominated debt to U.S. dollars, net of a $15 million loss for the year ended December 31, 2024, related to the change in the fair value of our cross currency swap contracts, recorded in other (expense) income, net in the consolidated statements of income.
(3)Translated earnings contract: Amount reflects the impact of the realized and unrealized gains and losses from the Japanese yen, South Korean won, Chinese yuan, euro, New Taiwan dollar and Mexican peso-denominated foreign currency hedges related to translated earnings, as well as the unrealized gains and losses of our British pound-denominated foreign currency hedges related to translated earnings.
(4)Acquisition-related costs: Amount reflects intangible amortization, inventory valuation adjustments and external acquisition-related deal costs, as well as other transaction related costs.
(5)Discrete tax items and other tax-related adjustments: Amount reflects certain discrete period tax items such as changes in tax law, the impact of tax audits, changes in tax reserves and changes in deferred tax asset valuation allowances, as well as other tax-related adjustments.
(6)Restructuring, impairment and other charges and credits: Amount reflects certain restructuring, impairment losses and other charges and credits, as well as other expenses, including severance, accelerated depreciation, asset write-offs and facility repairs resulting from power outages, and the recognition of cumulative foreign currency translation adjustments upon the substantial liquidation or disposition of a foreign entity, which are not related to ongoing operations. For the year ended December 31, 2024, amount includes $131 million of non-cash cumulative foreign currency translation losses required to be recognized upon the substantial liquidation or disposition of foreign entities, which was recorded in other (expense) income, net in the consolidated statements of income. Amount also includes $49 million of non-cash charges in one of our Emerging Growth Businesses relating to a customer that recently entered into a multi-jurisdictional restructuring effort including insolvency filings in certain countries. These charges primarily relate to the full write-down of upfront payments made to the customer, which were determined to be nonrecoverable, and recorded as a charge to net sales in the consolidated statements of income. Other charges recorded during 2024 related to asset write-offs associated with the exit of certain facilities and product lines. The activity in 2023 primarily relates to asset write-offs associated with the exit of certain facilities and product lines and severance charges across all segments.
(7)Litigation, regulatory and other legal matters: Amount reflects developments in commercial litigation, intellectual property disputes, adjustments to our estimated liability for environmental-related items and other legal matters.
(8)Pension mark-to-market adjustment: Amount primarily reflects defined benefit pension mark-to-market gains and losses, which arise from changes in actuarial assumptions and the difference between actual and expected returns on plan assets and discount rates.
(9)Loss (gain) on investments: Amount reflects the loss or gain recognized on investments due to mark-to-market adjustments for the change in fair value or the disposition of an investment.
(10)Loss (gain) on sale of assets: Amount represents the loss or gain recognized for the sale of assets, recorded in cost of sales, in the consolidated statements of income.
(11)Loss on sale of business: Amount reflects the loss recognized for the sale of a business, recorded in other (expense) income, net in the consolidated statements of income, and includes $14 million for the year ended December 31, 2024 of non-cash cumulative foreign currency translation losses related to the disposition of a foreign entity.
LIQUIDITY AND CAPITAL RESOURCES
Our financial condition and liquidity are strong. We are not aware of any known trends, demands, commitments, events or uncertainties that will result in or that are reasonably likely to result in a material decrease in our liquidity. In addition, other than items discussed, there are no known material trends, favorable or unfavorable, in our capital resources and no expected material changes in the mix of such resources.
Our major sources of funding for 2025 and beyond will be our operating cash flow, our existing balances of cash and cash equivalents and proceeds from any issuances of debt. We believe we have sufficient liquidity to fund operations and meet our obligations for the foreseeable future. Such obligations may include requirements for acquisitions, capital expenditures, debt repayments, dividend payments and share repurchases. We will continue to generate cash from operations and maintain access to our revolving credit facilities and commercial paper programs as discussed in more detail below.
Key Balance Sheet Data
We fund our working capital with cash from operations and, periodically, short-term and long-term borrowings. In addition, from time to time, we receive upfront cash from customers relating to long-term supply agreements, as well as cash incentives from government entities generally for capital expansion and related expenses.
The following table presents balance sheet and working capital measures (in millions):
December 31,
Working capital $ 3,073 $ 2,893
Current ratio 1.6:1 1.7:1
Trade accounts receivable, net of doubtful accounts $ 2,053 $ 1,572
Days sales outstanding 53
Inventories $ 2,724 $ 2,666
Inventory turns 3.2 3.2
Days payable outstanding (1)
54 52
Long-term debt $ 6,885 $ 7,206
Total debt $ 7,211 $ 7,526
Total debt to total capital 39% 39%
(1)Includes trade payables only.
We perform comprehensive reviews of our significant customers and their creditworthiness by analyzing their financial strength at least annually or more frequently for customers where we have identified a measure of increased risk. We closely monitor payments and developments to identify potential customer credit issues. We are not aware of any customer credit issues that could have a material impact on our liquidity.
We participate in accounts receivable management programs, including factoring arrangements to sell certain accounts receivable to third-party financial institutions or accelerate collections through our customer’s supply chain financing arrangements. Sales of accounts receivable are reflected as a reduction of accounts receivable in the consolidated balance sheets and the proceeds are included in cash flows from operating activities in the consolidated statements of cash flows. By utilizing these types of programs, we accelerated the collection of $182 million in accounts receivable during the three months ended December 31, 2024, which would have been collected during the normal course of business in the following quarter.
Cash Flows
The following table presents a summary of cash flow data (in millions):
Year ended December 31,
Net cash provided by operating activities $ 1,939 $ 2,005
Net cash used in investing activities $ (744) $ (1,000)
Net cash used in financing activities $ (1,164) $ (883)
Net cash provided by operating activities decreased by $66 million for the year ended December 31, 2024, when compared to the same period in the prior year, primarily driven by the decrease in net income partially offset by improvements in working capital.
Net cash used in investing activities improved by $256 million for the year ended December 31, 2024, when compared to the same period last year, primarily driven by lower capital expenditures of $425 million, partially offset by higher premiums paid on hedging contracts of $89 million.
Net cash used in financing activities increased by $281 million for the year ended December 31, 2024, when compared to the same period last year. During the year ended December 31, 2024, net cash used in financing activities primarily related to dividend payments of $986 million and purchases of common stock for treasury of $165 million. During the year ended December 31, 2023, net cash used in financing activities primarily related to dividend payments of $989 million and the redemption of preferred stock of $507 million, partially offset by $918 million in proceeds received from the issuance of euro-denominated notes in May 2023.
Sources of Liquidity
We generate strong ongoing cash flows from operations, which is our principal source of liquidity. During the years ended December 31, 2024 and 2023, cash flows provided by operating activities were $1.9 billion and $2.0 billion, respectively.
As of December 31, 2024, our cash and cash equivalents and available credit capacity included (in millions):
December 31, 2024
Cash and cash equivalents $ 1,768
Available credit capacity:
U.S. dollar revolving credit facility $ 1,500
Chinese yuan facilities $ 31
Cash and Cash Equivalents
We ended 2024 with $1.8 billion of cash and cash equivalents. Our cash and cash equivalents are held in various locations throughout the world and are generally unrestricted. We utilize a variety of strategies to ensure that our worldwide cash is available in the locations in which it is needed. As of December 31, 2024, approximately 64% of the consolidated cash and cash equivalents were held outside the U.S.
During the year ended December 31, 2024, the Company distributed an immaterial amount from foreign subsidiaries to their respective U.S. parent companies. As of December 31, 2024, Corning had approximately $1.6 billion of indefinitely reinvested foreign earnings. If we distribute our foreign cash balances to the U.S. or to other foreign subsidiaries, we could be required to accrue and pay withholding taxes. We do not foresee a need to repatriate any earnings for which we asserted permanent reinvestment. However, to help fund cash needs of the U.S. or other international subsidiaries as they arise, we repatriate available cash from certain foreign subsidiaries whose earnings are not permanently reinvested.
Debt Facilities and Other Sources of Liquidity
We have a commercial paper program pursuant to which we may issue short-term, unsecured commercial paper notes up to a maximum aggregate principal amount outstanding at any one time of $1.5 billion. Under this program, we may issue commercial paper from time to time and will use the proceeds for general corporate purposes. As of December 31, 2024, we did not have any commercial paper outstanding.
Our $1.5 billion Revolving Credit Agreement is available to support obligations under the commercial paper program and for general corporate purposes, if needed. There were no outstanding amounts under this facility as of December 31, 2024 and 2023.
Our Revolving Credit Agreement includes affirmative and negative covenants with which we must comply, including a leverage (debt to capital ratio) financial covenant. The required leverage ratio is a maximum of 60%. As of December 31, 2024, our leverage using this measure was approximately 39%. As of December 31, 2024, we were in compliance with all such covenants.
Our debt instruments contain customary event of default provisions, which allow the lenders the option of accelerating all obligations upon the occurrence of certain events. In addition, some of our debt instruments contain a cross default provision, whereby an uncured default exceeding a specified amount on one debt obligation, also would be considered a default under the terms of another debt instrument. As of December 31, 2024, we were in compliance with all such provisions.
We have access to certain Chinese yuan-denominated unsecured variable rate loan facilities, whose proceeds are used for capital investment and general corporate purposes. As of December 31, 2024, borrowings totaled $314 million and these facilities had variable interest rates ranging from 2.8% to 3.9% and maturities ranging from 2025 to 2032. As of December 31, 2024, Corning had 0.2 billion Chinese yuan of unused capacity, equivalent to approximately $31 million.
As a well-known seasoned issuer, we filed an automatic shelf registration statement with the SEC on December 1, 2023. Under this shelf registration statement we may offer, from time to time, debt securities, common stock, preferred stock, depository shares and warrants.
Refer to Note 10 (Debt) in the accompanying notes to the consolidated financial statements for additional information.
Customer Deposits, Deferred Revenue and Government Incentives
We receive cash deposits or consideration, generally non-refundable, from customers under long-term supply agreements. In addition, we receive government assistance, typically in the form of cash incentives primarily for capital expansion projects and tax credits that are refundable or transferable.
Refer to Note 1 (Summary of Significant Accounting Policies) and Note 3 (Revenue) in the accompanying notes to the consolidated financial statements for additional information.
Uses of Cash
Share Repurchase Agreement
Pursuant to the Share Repurchase Agreement (“SRA”) with Samsung Display Co., Ltd. (“SDC”), 22 million common shares held by SDC can be offered to be sold to Corning in specified tranches from time to time in calendar years 2024 through 2027. Corning may, at its sole discretion, elect to repurchase such common shares. If Corning elects not to repurchase the common shares and SDC sells the common shares on the open market, Corning is required to pay SDC a make-whole payment, subject to a 5% cap of the repurchase proceeds that otherwise would have been paid by Corning. As of December 31, 2024 and 2023, the fair value of the liability associated with this option, measured using Level 2 inputs, was not material.
Refer to Note 14 (Shareholders’ Equity) in the accompanying notes to the consolidated financial statements for additional information.
Share Repurchases
In 2019, the Board authorized the repurchase of up to $5.0 billion of additional common stock (“2019 Authorization”).
As of December 31, 2024, approximately $3.1 billion remains available under our 2019 Authorization, which does not have an expiration date and may be amended or terminated by the Board of Directors at any time without prior notice.
Refer to Note 14 (Shareholders' Equity) in the accompanying notes to the consolidated financial statements for additional information.
Common Stock Dividends
The Board’s decision to declare and pay future dividends will depend on our income and liquidity position, among other factors. We expect to declare quarterly dividends and fund payments with cash from operations.
On February 12, 2025, our Board of Directors declared a quarterly dividend of $0.28 per share of common stock, which will be payable on March 28, 2025.
Capital Expenditures
Capital expenditures were $1.0 billion, $1.4 billion and $1.6 billion during the years ended December 31, 2024, 2023 and 2022, respectively. We expect our 2025 capital expenditures to be approximately $1.3 billion.
Current Maturities of Short and Long-Term Debt
As of December 31, 2024, the maturity schedule of our existing long-term debt does not require significant cash outflows, with approximately $1.4 billion due over the next five years, of which $326 million is due in less than one year.
Refer to Note 10 (Debt) in the accompanying notes to the consolidated financial statements for additional information.
Defined Benefit Pension Plans
Our global pension plans, including our unfunded and non-qualified plans, were 86% funded as of December 31, 2024. Our largest single pension plan is our U.S. qualified plan, which accounted for 78% of our consolidated defined benefit pension plans’ projected benefit obligation, was 98% funded as of December 31, 2024.
The funded status of our pension plans is dependent upon multiple factors including actuarial assumptions, interest rates at year-end, prior investment returns and contributions made to the plans. During the year ended December 31, 2024, Corning made no voluntary contributions to our domestic defined benefit pension plan and cash contributions to our international pension plans were $9 million. During 2025, the Company anticipates making cash contributions of $10 million to the international pension plans.
Refer to Note 11 (Employee Retirement Plans) in the accompanying notes to the consolidated financial statements for additional information.
Commitments, Contingencies and Guarantees
A summary of our contractual obligations and other commercial commitments as of December 31, 2024 and details of our commitments as of December 31, 2024 related to executed leases that have not yet commenced are included within Note 12 (Commitments, Contingencies and Guarantees) and Note 5 (Leases), respectively, in the accompanying notes to the consolidated financial statements.
Off Balance Sheet Arrangements
Off balance sheet arrangements are transactions, agreements, or other contractual arrangements with an unconsolidated entity for which we have an obligation to the entity that is not recorded in our consolidated financial statements.
Our off balance sheet arrangements include guarantee and indemnity contracts. At the time a guarantee is issued, we are required to recognize a liability for the fair value or market value of the obligation it assumes. In the normal course of our business, we do not routinely provide significant third-party guarantees. Generally, third-party guarantees provided by us are limited to certain financial guarantees, including stand-by letters of credit and performance bonds. These guarantees have various terms and none of these guarantees are individually significant. We believe a significant majority of these guarantees and contingent liabilities will expire without being funded.
Refer to Note 12 (Commitments, Contingencies and Guarantees) in the accompanying notes to the consolidated financial statements for additional information.
ENVIRONMENT
Refer to Item 3. Legal Proceedings and Note 12 (Commitments, Contingencies and Guarantees) in the accompanying notes to the consolidated financial statements for information.
CRITICAL ACCOUNTING ESTIMATES
Our consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America. This requires us to make estimates and assumptions that affect reported amounts and related disclosures. Actual results could differ from those estimates. The following estimates are considered by management to be the most critical to the understanding of the consolidated financial statements as they require significant judgments that could materially impact our results of operations, financial position and cash flows.
Impairment of assets held for use
We are required to assess the recoverability of the carrying value of long-lived assets when an indicator of impairment has been identified. We perform this review each quarter and exercise judgment in assessing whether impairment indicators are present.
Manufacturing equipment includes certain components of production equipment that are constructed of precious metals, primarily platinum and rhodium. These metals are not depreciated because they have very low physical losses and are repeatedly reclaimed and reused in our manufacturing process over a very long useful life. The physical loss of precious metals in the manufacturing and reclamation process is treated as depletion and these losses are accounted for as a period expense based on actual units lost. Precious metals are reviewed for impairment as part of our assessment of long-lived assets. This review considers all our precious metals that are either in place in the production process; in reclamation, fabrication, or refinement in anticipation of re-use; or awaiting use to support increased capacity. Precious metals are only acquired to support our operations and are not held for trading or other non-manufacturing related purposes.
Examples of events or circumstances that may be indicative of impairments include, but are not limited to:
•A significant decrease in the market price of an asset;
•A significant change in the use of a long-lived asset or its physical condition;
•A significant adverse change in legal factors or in the business climate that could affect the value of the asset, including an adverse action or assessment by a regulator;
•An accumulation of costs significantly more than the amount originally expected for the acquisition or construction of an asset;
•A current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of an asset; and
•A current expectation that, more likely than not, an asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life.
For purposes of recognition and measurement of an impairment loss, a long-lived asset or assets is grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. We must exercise judgment in assessing the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Our assessment is performed at the operating segment level. For most of our operating segments, we concluded that locations or businesses within these segments which share production along the supply chain must be combined to appropriately identify cash flows that are largely independent of the cash flows of other assets and liabilities.
For long-lived assets, when impairment indicators are present, we compare estimated undiscounted future cash flows, including the eventual disposition of the asset group at market value, to the assets’ carrying value to determine if the asset group is recoverable. This assessment requires the exercise of judgment in assessing the future use of and projected value to be derived from the assets to be held and used. Assessments also consider changes in asset utilization, including the temporary idling of capacity and the expected timing for placing this capacity back into production.
For an asset group that fails the test of recoverability, the estimated fair value of long-lived assets is determined using an “income approach” that starts with the forecast of all the expected future net cash flows, including the eventual disposition at market value of long-lived assets, and considers the fair market value of all precious metals, if applicable. If there is an impairment, a loss is recorded to reflect the difference between the assets’ fair value and carrying value. Our estimates are based upon our historical experience, our commercial relationships and available external information about future trends. We believe fair value assessments are most sensitive to market growth and the corresponding impact on volume and selling prices and that these are also more subjective than manufacturing cost and other assumptions. We believe our current assumptions and estimates are reasonable and appropriate.
Income taxes
We are subject to income tax laws and regulations of the many jurisdictions in which we operate. These tax laws and regulations are complex and involve uncertainties in the application to our facts and circumstances that may be open to interpretation. We recognize benefits for these uncertain tax positions based upon a process that requires judgment regarding the technical application of the laws, regulations and various related judicial opinions. We record uncertain tax positions only when they are believed to have a less than 50% likelihood of being sustained on their technical merits and then only to the extent of the amount of tax benefit that is less than 50% likely of being realized upon settlement. In estimating these amounts, we must exercise judgment around factors such as the weighting of the tax law in our favor or alternatively, consider a negotiated compromise, and our willingness to dispute a tax authorities’ assertion to the level of appeal we believe is required to sustain our position. As a result, it is possible that our estimate of the benefits we will realize for uncertain tax positions may change when we become aware of new information affecting these judgments and estimates.
We must also assess the likelihood that we will be able to recover our deferred tax assets against future sources of taxable income and reduce the carrying amount of deferred tax assets by recording a valuation allowance if, based on all available evidence, it is more likely than not that all or a portion of such assets will not be realized. Inherent in this estimation process is the requirement for us to estimate future book and taxable income and possible tax planning strategies. These estimates require us to exercise judgment about our future results, the prudence and feasibility of possible tax planning strategies and the economic environments in which we do business. It is possible that actual results will differ from assumptions and require adjustments to allowances.
Fair value measures
As required, we use two kinds of inputs to determine the fair value of assets and liabilities: observable and unobservable. Observable inputs are based on market data or independent sources, while unobservable inputs are based on our own market assumptions. Once inputs have been characterized, we prioritize the inputs used to measure fair value into one of three broad levels. Characterization of fair value inputs is required for those accounting pronouncements that prescribe or permit fair value measurement. In addition, observable market data must be used when available and the highest-and-best-use measure should be applied to non-financial assets. Our major categories of financial assets and liabilities required to be measured at fair value are short-term and long-term investments, certain pension asset investments and derivatives. These categories use observable inputs only and are measured using a market approach based on quoted prices in markets considered active or in markets in which there are few transactions.
Derivative assets and liabilities may include foreign exchange forward contracts and foreign exchange option contracts that are measured using observable quoted prices for similar assets and liabilities. Included in our foreign exchange forward contracts and foreign exchange option contracts are foreign currency hedges that hedge our cash flow and translation exposure resulting from movements in the Japanese yen, South Korean won, New Taiwan dollar, Chinese yuan, British pound, euro and Mexican peso. In arriving at the fair value of our derivative assets and liabilities, we have considered the appropriate valuation and risk criteria, including such factors as credit risk of the relevant party to the transaction. Amounts related to credit risk are not material.
Refer to Note 13 (Financial Instruments) in the accompanying notes to the consolidated financial statements for additional information.
Loss contingencies
Accruals are recorded for various contingencies including legal proceedings, environmental matters and other claims that arise in the normal course of business. The accruals are based on judgment, the probability of losses, where applicable, the consideration of opinions of internal and/or external counsel and actuarial determined estimates. Refer to Item 3. Legal Proceedings and Note 12 (Commitments, Contingencies and Guarantees) in the accompanying notes to the consolidated financial statements for a discussion of Corning’s material litigation and environmental matters.
Pension and other postretirement employee benefits (“OPEB”)
We offer employee retirement plans consisting of defined benefit pension plans covering certain domestic and international employees and postretirement plans that provide health care and life insurance benefits for eligible retirees and dependents. The costs and obligations related to these benefits reflect our assumptions related to general economic conditions (particularly interest rates), expected return on plan assets, rate of compensation increase for employees and health care trend rates. The cost of providing plan benefits depends on demographic assumptions including retirements, mortality, turnover and plan participation. While management believes that the assumptions used are appropriate, differences in actual experience or changes in assumptions may affect our employee pension and other postretirement obligations, and current and future expense.
The following table presents our actual and expected return (loss) on assets, as well as the corresponding percentages (in millions, except percentages):
December 31,
Actual return (loss) on plan assets - Domestic plans $ 303 $ 281 $ (728)
Expected return on plan assets - Domestic plans 179 176 210
Actual (loss) return on plan assets - International plans
(6) 10 (139)
Expected return on plan assets - International plans 16 13 9
Weighted-average actual and expected return on assets:
Actual return (loss) on plan assets - Domestic plans 11.74 % 10.94 % (20.05) %
Expected return on plan assets - Domestic plans 6.75 % 6.75 % 6.00 %
Actual (loss) return on plan assets - International plans
(1.19) % 2.54 % (26.26) %
Expected return on plan assets - International plans 4.34 % 3.85 % 1.64 %
As of December 31, 2024, the Projected Benefit Obligation (“PBO”) for U.S. pension plans was $3.2 billion.
The following table presents the estimated increases (decreases) in future ongoing pension expense and projected benefit obligation assuming a 25 basis point change in the key assumptions for our U.S. pension plans (in millions):
Change in ongoing pension expense Change in projected benefit obligation
25 basis point decrease in each spot rate $ (1) $ 75
25 basis point increase in each spot rate $ 1 $ (72)
25 basis point decrease in expected return on assets $ 7
25 basis point increase in expected return on assets $ (7)
The above sensitivities reflect the impact of changing one assumption at a time. Economic factors and conditions often affect multiple assumptions simultaneously and the effects of changes in key assumptions are not necessarily linear. These changes in assumptions would have no effect on our funding requirements.
The following table presents the estimated increases (decreases) in future ongoing pension expense and the Accumulated Postretirement Benefit obligation (“APBO”) assuming a 25 basis point change in the key assumptions for our U.S. OPEB plans (in millions):
Change in ongoing OPEB expense Change in APBO
25 basis point decrease in each spot rate $ 1 $ 9
25 basis point increase in each spot rate $ (1) $ (8)
The above sensitivities reflect the impact of changing one assumption at a time. Economic factors and conditions often affect multiple assumptions simultaneously and the effects of changes in key assumptions are not necessarily linear.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Item 7A. Quantitative and Qualitative Disclosures About Market Risks
We operate and conduct business in many foreign countries and as a result are exposed to movements in foreign currency exchange rates. Our exposure to exchange rates has the following effects:
•Exchange rate movements on financial instruments and transactions denominated in foreign currencies that impact earnings; and
•Exchange rate movements upon conversion of net assets and net income of foreign subsidiaries for which the functional currency is not the U.S. dollar.
Our most significant foreign currency exposure relates to the Japanese yen, South Korean won, New Taiwan dollar, Chinese yuan, euro and Mexican peso. We seek to mitigate the impact of exchange rate movements in our consolidated statements of income by using over-the-counter (“OTC”) derivative instruments including foreign exchange forward and option contracts. In general, these hedges expire coincident with the timing of the underlying foreign currency commitments and transactions.
We are exposed to potential losses in the event of non-performance by our counterparties to these derivative contracts. However, we minimize this risk by maintaining a diverse group of highly-rated major financial institutions as our counterparties. We do not expect to record any losses as a result of such counterparty default. Neither we nor our counterparties are required to post collateral for these financial instruments.
Our cash flow hedging activities utilize OTC foreign exchange forward contracts to reduce the risk that movements in exchange rates will adversely affect the net cash flows resulting from the sale of products to foreign customers and purchases from foreign suppliers. We also use OTC foreign exchange forward and option contracts that are not designated as hedged instruments. These contracts are used to offset economic currency risks. The undesignated hedges limit exposure to foreign functional currency fluctuations related to certain subsidiaries’ monetary assets, monetary liabilities and net earnings in foreign currencies. A significant portion of our non-U.S. revenue is denominated in Japanese yen. When this revenue is translated back to U.S. dollars, we are exposed to foreign exchange rate movements in the Japanese yen. To protect translated earnings against movements in the Japanese yen, we have entered into a series of option contracts and average rate forwards. Since inception of the Company’s Japanese yen-denominated debt, the Japanese yen has weakened and the U.S. dollar value of these liabilities has decreased, generating unrealized foreign exchange gains that have been recognized over time in the consolidated statements of income. In 2024, to economically lock in unrealized foreign exchange gains, the Company entered into the cross currency swap contracts relating to a portion of the Company’s Japanese yen-denominated debt.
We use a sensitivity analysis to assess the market risk associated with foreign currency exposure. Market risk is defined as the potential change in fair value of assets and liabilities resulting from an adverse movement in foreign currency exchange rates. As of December 31, 2024, with respect to open foreign exchange forward, option and cross currency swap contracts and foreign denominated debt with values exposed to exchange rate movements, a 10% adverse movement in quoted foreign currency exchange rates could result in a loss in fair value of these instruments of $0.8 billion compared to $0.6 billion as of December 31, 2023. Specific to the Japanese yen, a 10% adverse movement in quoted yen exchange rates could result in a loss in fair value of these instruments of $0.3 billion as of December 31, 2024 and 2023, respectively. Management expects that these hypothetical losses from a 10% adverse movement in quoted foreign currency exchange rates on the derivative financial instruments should largely offset gains on the assets, liabilities and future transactions being hedged.

Corning’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the U.S. Corning’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of Corning’s assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the U.S., and that Corning’s receipts and expenditures are being made only in accordance with authorizations of Corning’s management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of Corning’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.
Management conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting based on the framework in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
Based on this evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2024. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2024 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report which is included in Part IV, Item 15 of this Annual Report on Form 10-K.
(b)Changes in Internal Control Over Financial Reporting
There were no changes in the Company’s internal control over financial reporting identified by the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during the most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, internal control over financial reporting.
