Summary of Significant Accounting Policies Summary of Significant Accounting Policies
Basis of Presentation and Principles of Consolidation
In these notes, the terms “Corning,” “Company,” “we,” “us,” or “our” mean Corning Incorporated and its subsidiary companies.
The consolidated financial statements include the accounts of Corning Incorporated and our consolidated subsidiaries (collectively, the “Company”), consisting of our wholly-owned subsidiaries and those entities in which we have a variable interest and of which we are the primary beneficiary, and are consolidated in conformity with accounting principles generally accepted in the United States of America (“GAAP”). In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary to state fairly the financial position, results of operations and cash flows for the periods presented. All intercompany accounts, transactions and profits have been eliminated. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). These consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (“2024 Form 10-K”). The results of operations for the interim periods are not necessarily indicative of results which may be expected for any other interim period or for the full year.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities in the consolidated financial statements and accompanying notes. Significant estimates and assumptions in these consolidated financial statements require the exercise of judgment. Due to the inherent uncertainty involved in making estimates, actual results could differ materially from these estimates.
The results of businesses acquired in business combinations are included in the Company’s consolidated financial statements from the date of acquisition. Other than the acquisition detailed in Note 6 (Acquisition), acquisitions during the six months ended June 30, 2025 and 2024 were not significant, individually or in the aggregate.
The non-controlling interest as recorded in the consolidated financial statements represents amounts attributable to the minority shareholders of less-than-wholly-owned consolidated subsidiaries, including Hemlock Semiconductor Group (“HSG”) and other subsidiaries primarily within our Optical Communications segment.
Certain prior year amounts have been reclassified to conform to the current year presentation, including the recast of the Company’s segment related disclosures to align with the new reportable segments as of January 1, 2025. Refer to Note 16 (Reportable Segments) for additional information. These reclassifications had no impact on the results of operations, financial position or changes in shareholders’ equity.

There were no material restructuring, impairment and other charges and credits during the three and six months ended June 30, 2025.
During the three and six months ended June 30, 2024, the Company recorded $138 million and $129 million, respectively, in restructuring, impairment and other charges and credits, of which $141 million and $121 million, respectively, were reflected in cost of sales in the consolidated statements of income, primarily relating to asset write-offs in the second quarter associated with the closure of a display manufacturing plant.

Customer Deposits
As of June 30, 2025 and December 31, 2024, Corning had customer deposits of approximately $1.1 billion. Most of these customer deposits were non-refundable and allowed customers to secure rights to products produced under long-term supply agreements, generally over a period of up to ten years. As products are delivered to customers, Corning will recognize revenue and reduce the amount of the customer deposit liability.
For the three months ended June 30, 2025 and 2024, customer deposits recognized were $19 million and $11 million, respectively. For the six months ended June 30, 2025 and 2024, customer deposits recognized were $81 million and $91 million, respectively.
Refer to Note 8 (Other Liabilities) for additional information.
Deferred Revenue
As of June 30, 2025 and December 31, 2024, Corning had deferred revenue of approximately $763 million and $833 million, respectively. Deferred revenue was primarily related to the performance obligations of non-refundable consideration previously received by HSG from its customers under long-term supply agreements.
Deferred revenue is tracked on a per-customer contract-unit basis. As customers take delivery of the committed volumes under the terms of the contract, a per-unit amount of deferred revenue is recognized when control of the promised goods is transferred to the customer based upon the units delivered compared to the remaining contractual units. For the three and six months ended June 30, 2025 and 2024, the amount of deferred revenue recognized in the consolidated statements of income was not material.

Effective tax rate14.4%29.1%16.9%25.9%
For the three and six months ended June 30, 2025, the effective tax rate differed from the United States (“U.S.”) statutory rate of 21%, primarily due to foreign derived intangible income, adjustments to share-based compensation and non-taxable items, partially offset by certain pre-tax losses with no corresponding expected tax benefit.

For the three and six months ended June 30, 2024, the effective tax rate differed from the U.S. statutory rate of 21%, primarily due to certain pre-tax losses with no corresponding expected tax benefit. The losses were mostly driven by asset write-offs associated with the closure of a display manufacturing plant. Refer to Note 2 (Restructuring, Impairment and Other Charges and Credits) for additional information.
Corning Precision Materials, a South Korean subsidiary, is currently appealing certain tax assessments and tax refund claims for tax years 2010 through 2019. The Company was required to deposit the disputed tax amounts with the South Korean government as a condition of its appeal of any tax assessment. The non-current receivable balance was $265 million and $253 million as of June 30, 2025 and December 31, 2024, respectively, for the amount on deposit with the South Korean government. Corning believes that it is more likely than not the Company will prevail in the appeals process relating to these matters.
On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the United States. The OBBBA includes various tax law changes, including the permanent extension of certain provisions originally enacted under the Tax Cuts and Jobs Act, modifications to the international tax framework and the reinstatement of favorable treatment for certain business tax provisions. These include 100% bonus depreciation, immediate expensing of domestic research and development costs and revised limitations on the deductibility of business interest expense. The provisions of the OBBBA are subject to multiple effective dates, with some effective beginning in 2025 and others phased in through 2027. The Company is currently evaluating the provisions of the OBBBA and is assessing the potential impact on its consolidated financial statements.

Business Combination, Asset Acquisition, Transaction between Entities under Common Control, and Joint Venture Formation [Abstract]  
Acquisition Acquisition
In April 2025, the Company acquired 100% of the equity interests in a U.S. solar module manufacturing facility. The total fair value of purchase price consideration was $278 million, consisting of $17 million in cash paid at closing, $111 million in notes payable due within 2025, and $150 million in potential contingent consideration. The contingent consideration is comprised of annual earn-out payments with a final payment due in the sixth post-closing year. Earn-out payments are based on cumulative free cash flow, with no limitation on the total amount, and the final payment is the lesser of $98 million or an amount based on the net liquidation value of the acquired entity at the time payment is due.

The contingent payments are classified as liabilities and measured at fair value utilizing the income approach with Level 3 inputs. Fair value at the acquisition date and as of June 30, 2025 was $104 million for the earn-out payments and $46 million for the final payment. Key assumptions include projections for revenue, margins, market prices and discount rates. Subsequent changes in fair value are recognized on a recurring basis and reflected within other (expense) income, net in the consolidated statements of income.

The total purchase price of $278 million was allocated to the identifiable assets acquired and liabilities assumed based on their estimated fair values at the acquisition date and consisted of the following (in millions):

Inventories$41 
Property, plant and equipment167 
Accounts payable(36)

(1)Includes approximately $64 million in other assets and $64 million in other liabilities relating to acquired operating leases for the manufacturing facility.
(2)Goodwill reflects the expected synergies, expanded market opportunities and other benefits from vertically integrating the acquired solar module business into the Company’s operations. The goodwill is not deductible for tax purposes and has been assigned to a reporting unit within Hemlock and Emerging Growth Businesses.

The revenue, earnings contribution and transaction-related costs were not material to the Company's consolidated financial results for the three and six months ended June 30, 2025.

Debt Disclosure [Abstract]  
Debt Debt
Based on borrowing rates currently available to us for loans with similar terms and maturities, the fair value of long-term debt was $6.3 billion and $6.4 billion compared to the carrying value of $6.7 billion and $6.9 billion as of June 30, 2025 and December 31, 2024, respectively. The Company measures the fair value of its long-term debt using Level 2 inputs based primarily on current market yields for its existing debt traded in the secondary market.
During the three and six months ended June 30, 2025, the Company repaid ¥10.0 billion (equivalent to $69.6 million) aggregate principal amount of its 0.722% debentures due 2025.
Corning is the obligor to Chinese yuan-denominated variable rate loan facilities, whose proceeds are used for capital investment and general corporate purposes. During the six months ended June 30, 2025, the Company repaid $209 million of its existing loan amounts outstanding. In addition, the Company entered into new Chinese yuan-denominated variable rate loan facilities and incurred $285 million in borrowings under these facilities during the six months ended June 30, 2025. As of June 30, 2025 and December 31, 2024, amounts outstanding under these facilities totaled $394 million and $314 million, respectively, and these facilities had variable interest rates ranging from 2.2% to 3.4% and 2.8% to 3.9%, respectively, and maturities ranging from 2025 to 2032. As of June 30, 2025, Corning had ¥0.2 billion Chinese yuan of unused capacity, equivalent to approximately $22 million.
On July 28, 2025, the Company entered into a new credit agreement (the “New Credit Agreement”), which replaces the Company’s existing $1.5 billion credit agreement dated June 6, 2022 (the “Existing Credit Agreement”). The New Credit Agreement provides a committed $1.5 billion unsecured multi-currency line of credit and expires July 28, 2030. As of June 30, 2025, there were no outstanding amounts under the Existing Credit Agreement or the New Credit Agreement.
During the first quarter of 2025, the Company de-designated €100 million ($117 million equivalent as of June 30, 2025) notional of the €300 million ($351 million equivalent as of June 30, 2025) 3.875% Notes due 2026 as a net investment hedge. Refer to Note 13 (Financial Instruments) for additional information.

From time to time, the Company enters into various cross currency swap contracts to economically lock in unrealized foreign exchange gains relating to a portion of the Company’s Japanese yen-denominated debt. Refer to Note 13 (Financial Instruments) for additional information.

Leases [Abstract]  
Leases Leases
During the first quarter of 2025, Corning entered into a lease primarily for production related equipment, that has not yet commenced, of approximately $261 million on an undiscounted basis. The lease is expected to commence late in 2026 with a lease term of 16 years. This lease is expected to be classified as a finance lease and the amount of right-of-use asset and lease liability will be determined and recorded upon lease commencement.
Corning entered into an equipment lease (“Equipment Lease”) on June 17, 2024, with an initial estimated purchase and installation cost of $365 million, for the equipment to be installed and operated within the solar manufacturing facility in Hemlock, Michigan. The Company is the procurement and installation agent on behalf of the lessor. On May 9, 2025, the Equipment Lease was amended to increase the aggregate commitment amount (“Amended Equipment Lease”). As of June 30, 2025 the estimated purchase and installation cost subject to this Amended Equipment Lease is $586 million.
The Amended Equipment Lease is expected to commence in the latter part of 2025 and has a lease term of five years with obligations to purchase the equipment at lease maturity. The Equipment Lease is expected to be classified as a finance lease and the amount of right-of-use asset and lease liability will be determined and recorded upon lease commencement. Based on the current estimate of the purchase and installation cost, the estimated undiscounted lease payments are approximately $680 million, of which $80 million, $155 million, $146 million and $138 million to be paid in 2026, 2027, 2028 and 2029, respectively, and $161 million to be paid thereafter.

Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingencies Commitments and Contingencies
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 below. 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.

Dow Corning Environmental Claims
Beginning in September 2019, Dow formally notified Corning of certain environmental matters for which Dow asserts that it has or will experience losses arising from remediation and response at a number of sites. Subject to certain conditions and limits, Corning may be required to indemnify Dow for up to 50% of such losses. Costs incurred were not material to the periods presented and, as of June 30, 2025, the amount reserved was not material.
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 June 30, 2025 and December 31, 2024, Corning had accrued approximately $92 million and $78 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.

Cross Currency Swap Contracts
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. During 2025 and 2024, the Company entered into various cross currency swap contracts relating to a portion of the Company’s Japanese yen-denominated debt in order to economically lock in unrealized foreign exchange gains. At inception of these instruments, Corning receives a net amount from the counterparties, representing an exchange of the notional amounts at a fixed foreign exchange rate of Japanese yen to U.S. dollar and initially records this amount as a derivative liability. During the six months ended June 30, 2025 and 2024, Corning received net payments of $24 million and $68 million, respectively. As of June 30, 2025 and December 31, 2024, the fair value of the derivative liability associated with these contracts is $156 million and $148 million, respectively.
Net Investment Hedges
In May 2023, the Company issued €300 million ($351 million equivalent as of June 30, 2025) 3.875% Notes due 2026 (“2026 Notes”) and €550 million ($644 million equivalent as of June 30, 2025) 4.125% Notes due 2031 (“2031 Notes”). The proceeds from the 2026 Notes and 2031 Notes were received in euros and converted to U.S. dollars on the date of issuance. In 2023, the Company designated the full amount of its euro-denominated 2026 Notes and 2031 Notes with a total notional amount of €850 million ($995 million equivalent as of June 30, 2025), which are non-derivative financial instruments, as net investment hedges against its investments in certain European subsidiaries with euro functional currencies. During the first quarter of 2025, the Company de-designated €100 million ($117 million equivalent as of June 30, 2025) notional of the 2026 Notes as a net investment hedge.
During the first quarter of 2025, the Company entered into various foreign exchange forward contracts with notional amounts totaling €110 million ($129 million equivalent as of June 30, 2025) and ¥40.2 billion ($277 million equivalent as of June 30, 2025) and designated these forward contracts as net investment hedges against its investments in certain European subsidiaries with euro functional currencies and its Taiwanese subsidiary with Japanese yen functional currency, respectively.
During the second quarter of 2025, the Company entered into various foreign exchange forward contracts with notional amounts totaling €270 million ($316 million equivalent as of June 30, 2025) and ¥34.4 billion ($237 million equivalent as of June 30, 2025) and designated these forward contracts as net investment hedges against its investments in certain European subsidiaries with euro functional currencies and its Taiwanese subsidiary with Japanese yen functional currency, respectively. Additionally, the Company de-designated €180 million ($211 million equivalent as of June 30, 2025) and ¥34.4 billion ($237 million equivalent as of June 30, 2025) of existing net investment hedges.
As of June 30, 2025, these net investment hedges are deemed to be effective.

Leased Precious Metals Contracts
The carrying amount of the leased precious metals pool, which is included within property, plant and equipment, net of accumulated depreciation in the consolidated balance sheets, is $52 million and $58 million as of June 30, 2025 and December 31, 2024, respectively. The carrying amount of the leased precious metals pool includes cumulative fair value losses of $25 million and $108 million as of June 30, 2025 and December 31, 2024, respectively. These losses are offset by changes in the fair value of hedges.

Fixed Rate Cumulative Convertible Preferred Stock, Series A
The Company had 2,300 outstanding shares of Fixed Rate Cumulative Convertible Preferred Stock, Series A (the “Preferred Stock”) as of December 31, 2020. On January 16, 2021, the Preferred Stock became convertible into 115 million common shares. On April 5, 2021, Corning and Samsung Display Co., Ltd. (“SDC”) executed the Share Repurchase Agreement (“SRA”) and the Preferred Stock was fully converted as of April 8, 2021. Immediately following the conversion, Corning repurchased and retired 35 million of the common shares held by SDC for an aggregate purchase price of approximately $1.5 billion.
Pursuant to the SRA, with respect to the remaining 80 million common shares outstanding held by SDC, 58 million common shares are subject to a seven-year lock-up period expiring in 2027. The remaining 22 million common shares 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 June 30, 2025 and December 31, 2024, the fair value of the liability associated with this option, measured using Level 2 significant other observable inputs, was not material.
Share Repurchase Program
In 2019, the Board authorized the repurchase of up to $5.0 billion of additional common stock (“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. As of June 30, 2025, approximately $3.0 billion remains available under the Company’s 2019 Authorization.
During the three and six months ended June 30, 2025, the Company repurchased 0.7 million shares and 2.8 million shares, respectively, for approximately $33 million and $133 million, respectively. During the three and six months ended June 30, 2024, the company repurchased 3 million common shares for $105.4 million pursuant to the terms of the SRA, as discussed above.

Segment Reporting [Abstract]  
Reportable Segments Reportable Segments
As of January 1, 2025, the Company began managing its Automotive Glass Solutions business together with its Environmental Technologies business, forming the Automotive segment. In addition, the Display Technologies segment has been renamed to Display.
The segment information presented below has been recast for the comparative period presented for the Automotive segment.

As a result of the above changes, the Company has five reportable segments for financial reporting purposes, as follows:

•Optical Communications – manufactures carrier network and enterprise network components for the telecommunications industry; 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, including hyperscale data centers, sold to businesses, governments and individuals for their own use.
•Display – manufactures high quality glass substrates for flat panel displays, including liquid crystal displays and organic light-emitting diodes that are used primarily in televisions, notebook computers, desktop monitors, tablets and handheld devices.
•Specialty Materials – manufactures products that provide material formulations for glass, glass ceramics and crystals, as well as precision metrology instruments and software to meet demand for unique customer needs across a wide variety of commercial and industrial markets, including materials optimized for mobile consumer electronics, semiconductor equipment optics and consumables, aerospace and defense optics, radiation shielding products, sunglasses and telecommunications components.
•Automotive – manufactures ceramic substrates and filter products for emissions control systems in mobile applications; as well as glass products for the interior and exterior of vehicles.
•Life Sciences – develops, manufactures, and supplies laboratory products, including labware, equipment, media, serum and reagents, enabling workflow solutions for drug discovery and bioproduction.

All other businesses that do not meet the quantitative threshold for separate reporting have been grouped as Hemlock and Emerging Growth Businesses. Net sales for this group are mainly attributable to HSG, an operating segment that produces solar and semiconductor products. The emerging growth businesses primarily consist of Pharmaceutical Technologies and the Emerging Innovations Group.
The chief operating decision maker (“CODM”) of the Company is the Company's chief executive officer. The CODM assesses performance and decides how to allocate resources, including employees, financial or capital resources, based on segment net income, which includes certain overhead allocations directly attributable to each of the segments. The CODM considers actual-to-actual variances on a quarterly basis when making decisions about allocating capital and other resources to the segments and to assesses the performance for each segment.
Financial results for the reportable segments are prepared on a basis consistent with the internal disaggregation of financial information to assist the CODM in making internal operating decisions. As a significant portion of segment revenues and expenses are denominated in currencies other than the U.S. dollar, management believes it is important to understand the impact on segment net sales and segment net income of translating these currencies into U.S. dollars. Therefore, the Company utilizes constant-currency reporting for the Optical Communications, Display, Specialty Materials, Automotive and Life Sciences segments to exclude the impact on segment sales and segment net income from the Japanese yen, South Korean won, Chinese yuan, New Taiwan dollar, Mexican peso and euro, as applicable to the segment. The Company believes 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. The most significant constant-currency adjustment relates to the Japanese yen exposure within the Display segment.
The constant-currency rates established for core performance measures are long-term management-determined rates, which are closely aligned with the Company’s hedging instrument rates. These hedging instruments may include, but are not limited to, foreign exchange forward or option contracts and foreign-denominated debt. Effective January 1, 2025, management updated the constant-currency rates and the updated rates were applied prospectively beginning with reporting periods in 2025. Comparative results were not recast and are reported based on the 2024 rates.

Constant-currency rates used are as follows and are applied to the respective periods presented and to all foreign exchange exposures during the period, even though the Company may be less than 100% hedged:
CurrencyJapanese yenSouth Korean wonChinese yuanNew Taiwan dollarMexican pesoEuro
2024 Rate¥107₩1,175¥6.7NT$31MX$20€0.81
2025 Rate¥120₩1,250¥6.9NT$31MX$21€0.88
In addition, certain income and expenses are excluded from segment net income (loss) and included in the unallocated amounts in the reconciliation of reportable segment net income (loss) to net income. These items are not used by the CODM in allocating resources or evaluating the results of the segments and include the following: the impact of translating foreign 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 segment. Although these amounts are excluded from segment results, they are included in reported consolidated results.
Corning’s administrative and staff functions are performed on a centralized basis and such costs and expenses are allocated among the segments differently than they would be for stand-alone financial reporting purposes. These include certain costs and expenses of shared services, such as information technology, human resources, legal, finance and supply chain management. Expenses that are not allocated to the segments are included in the reconciliation of reportable segment net income (loss) to net income. Segment net income (loss) may not be consistent with measures used by other companies.

In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary to state fairly the financial position, results of operations and cash flows for the periods presented. All intercompany accounts, transactions and profits have been eliminated. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). These consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (“2024 Form 10-K”). The results of operations for the interim periods are not necessarily indicative of results which may be expected for any other interim period or for the full year.
Principles of Consolidation
The consolidated financial statements include the accounts of Corning Incorporated and our consolidated subsidiaries (collectively, the “Company”), consisting of our wholly-owned subsidiaries and those entities in which we have a variable interest and of which we are the primary beneficiary, and are consolidated in conformity with accounting principles generally accepted in the United States of America (“GAAP”). In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary to state fairly the financial position, results of operations and cash flows for the periods presented. All intercompany accounts, transactions and profits have been eliminated. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). These consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (“2024 Form 10-K”). The results of operations for the interim periods are not necessarily indicative of results which may be expected for any other interim period or for the full year.
Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and the disclosure of contingent assets and liabilities in the consolidated financial statements and accompanying notes. Significant estimates and assumptions in these consolidated financial statements require the exercise of judgment. Due to the inherent uncertainty involved in making estimates, actual results could differ materially from these estimates.
