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 its consolidated subsidiaries (collectively, the “Company”), consisting of its wholly-owned subsidiaries, partially-owned subsidiaries in which the Company holds a controlling financial interest through ownership of a majority of the voting interests and those entities in which the Company has a variable interest and of which the Company is 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 balances, 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, 2025 (“2025 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 related disclosures of contingent assets and liabilities on 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 non-controlling interest recorded on the consolidated financial statements represents amounts attributable to the minority shareholders of less-than-wholly-owned consolidated subsidiaries, including Hemlock Semiconductor Operations, a majority owned entity within our Solar segment, and US Conec, a variable interest entity within our Optical Communications segment, of which the Company is the primary beneficiary, and other subsidiaries.
Certain prior year amounts have been reclassified to conform to the current year presentation, including a recast of the Company’s segment related disclosures to align with its new reportable segments as of the first quarter of fiscal year 2026. Refer to Note 14 (Reportable Segments) for additional information. These reclassifications had no impact on the results of operations, financial position or changes in shareholders’ equity.

Contract Liabilities
As of June 30, 2026 and December 31, 2025, the Company had contract liabilities of $2.7 billion and $2.3 billion, respectively. Contract liabilities include customer deposits received prior to the satisfaction of performance obligations and deferred revenue related to non-refundable consideration received in advance of performance. Refer to Note 5 (Other Assets and Other Liabilities) for additional information.
Customer deposits allow customers to secure rights to products produced by Corning under long-term supply agreements, typically over periods of up to 10 years. As products are delivered, Corning recognizes revenue and reduces the related customer deposit liability by applying such amounts against customer receivables. During the second quarter of 2026, the Company recorded an approximate $0.7 billion net contract liability, consisting of a $1.0 billion customer deposit under a long-term supply agreement extending through December 31, 2029, partially offset by $296 million for a warrant issued to the customer, accounted for as consideration payable to the customer and measured at its grant-date fair value. The fair value of the warrant will be recognized as a reduction of revenue as sales occur under the agreement. Refer to Note 12 (Shareholders’ Equity) for additional information.
During the three and six months ended June 30, 2026, the Company applied $28 million and $214 million, respectively, of customer deposits included in the beginning-of-period contract liability balance to customer receivables. During the three and six months ended June 30, 2025, the Company applied $19 million and $81 million, respectively, of customer deposits included in the beginning-of-period contract liability balance to customer receivables.
Deferred revenue is tracked on a per-customer, contract-unit basis. As customers take delivery of committed volumes under the contract terms, deferred revenue is recognized on a per-unit basis upon transfer of control of the promised goods, based on units delivered relative to total contractual units. During the three and six months ended June 30, 2026, the Company recognized $73 million and $118 million, respectively of revenue that was included in the beginning-of-period contract liability balance. During the three and six months ended June 30, 2025, the Company recognized $44 million and $83 million, respectively of revenue that was included in the beginning-of-period contract liability balance.

Leases Leases
Recently commenced leases
For the six months ended June 30, 2026, the Company commenced and recognized $224 million of right-of-use assets and lease liabilities under various leases for equipment placed in service within the solar manufacturing facility in Hemlock, Michigan. These leases were classified as finance leases, with lease terms ranging from five to eight years. Related to these assets, the Company recognized $74 million in Advanced Manufacturing Investment Credits under Section 48D of the Internal Revenue Code, as amended under the One Big Beautiful Bill Act (“48D credits”), which reduced the carrying value of these right-of-use assets.
Leases not yet commenced
The Company has entered into various leases that have not yet commenced in an aggregate amount of $348 million as of June 30, 2026, on an undiscounted basis, primarily for production-related equipment associated with the solar manufacturing facility in Hemlock, Michigan. The leases are expected to commence in 2026 with lease terms ranging from five to 16 years. The leases are expected to be classified as finance leases and the amount of right-of-use assets and lease liabilities will be determined and recorded upon lease commencement. Once placed in service, the Company will reduce the amount of right-of-use assets by any 48D credits, which are estimated to be approximately $54 million

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 $7.4 billion and $7.3 billion compared to recorded book values of $7.8 billion and $7.6 billion as of June 30, 2026 and December 31, 2025, 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.
The Company maintains a revolving credit facility (the “Revolving Credit Facility”), which provides a committed $1.5 billion unsecured multi-currency line of credit and expires in 2030. As of June 30, 2026, there were no outstanding amounts under the Revolving Credit Facility.
Certain of Corning’s subsidiaries are the obligors to Chinese yuan-denominated unsecured variable rate loan facilities, whose proceeds are used for capital investment and related corporate purposes. During the three and six months ended June 30, 2026, the Company entered into new Chinese yuan-denominated variable rate loan facilities and incurred $22 million and $448 million, respectively, in short-term borrowings under these facilities. During the three months ended June 30, 2026, the Company repaid $313 million of principal balance under these facilities. As of June 30, 2026, the amount outstanding under these facilities totaled $536 million, of which $491 million is due within one year.

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.

Environmental Claims
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 21 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, 2026 and December 31, 2025, Corning had accrued $85 million and $89 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.

Share-Based Compensation Share-Based Compensation
Total share-based compensation expense was $135 million and $250 million for the three and six months ended June 30, 2026, respectively, and $63 million and $117 million for the three and six months ended June 30, 2025, respectively. The income tax benefit realized from share-based compensation was $83 million and $117 million for the three and six months ended June 30, 2026, respectively, and $9 million and $17 million for the three and six months ended June 30, 2025, respectively.
The increase in share‑based compensation expense and the related income tax benefit for the three and six months ended June 30, 2026 was primarily driven by the Company’s higher stock price, which increased the fair value of performance-based restricted stock units, and the related income tax benefits realized from awards that vested during the period.

Effective tax rate6.2%14.4%13.7%16.9%
For the three months ended June 30, 2026, the effective tax rate differed from the United States (“U.S.”) statutory rate of 21%, primarily due to adjustments to share-based compensation, government incentives and foreign derived deduction eligible income. For the six months ended June 30, 2026, the effective tax rate differed from the U.S. statutory rate of 21%, primarily due to adjustments to share-based compensation, government incentives, changes in reserves and foreign derived deduction eligible income partially offset by the impact of an unfavorable tax ruling in South Korea.
For the three and six months ended June 30, 2025, the effective tax rate differed from the 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.
The Internal Revenue Service (“IRS”) is currently conducting examinations of the Company’s U.S. federal income tax returns for the years 2015 through 2018 and 2019 through 2020, including matters related to the one-time transition tax enacted under the Tax Cuts and Jobs Act of 2017. If challenged, Corning believes that it is at least more likely than not to sustain its position relating to these matters. However, if the Company is ultimately unsuccessful in defending its position, the impact could be material to its consolidated financial statements.
Corning Precision Materials, a South Korean subsidiary, is currently appealing certain tax assessments and tax refund claims for tax years 2013 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. On February 11, 2026, the Company received a final unfavorable ruling relating to a tax dispute for the tax years 2010 through 2012. As a result, the Company has reduced its receivable balance by $92 million through a noncash charge to the income tax provision in the first quarter of 2026. In addition, the Company has established an immaterial reserve against the remaining amount on deposit related to the tax year 2013. Corning continues to believe that it is more likely than not that the Company will prevail in the appeals process relating to the remaining matters. The non-current receivable balance was $134 million and $248 million as of June 30, 2026 and December 31, 2025, respectively, for the amount on deposit with the South Korean government.
Certain foreign subsidiaries in Luxembourg were subject to tax disputes for the tax years 2015 through 2018. While we maintained a more likely than not position with respect to these matters, on March 12, 2026, the Company received a final unfavorable ruling. As a result, during the first quarter of 2026, the Company reduced deferred tax assets associated with net operating loss carryforwards by $879 million and reduced the related valuation allowance by a corresponding amount. Because the reduction in deferred tax assets was offset by a corresponding reduction in the related valuation allowance, the final ruling had no impact on the Company’s income tax provision.

On February 11, 2026 and April 30, 2026, Corning’s Board of Directors declared dividends of $0.28 per share of common stock, which were paid on March 30, 2026 and June 29, 2026, respectively.
On June 24, 2026, Corning’s Board of Directors declared a quarterly dividend of $0.28 per share of common stock, which will be payable on September 29, 2026.
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, 2026, approximately $3.0 billion remains available under the Company’s 2019 Authorization.
During the three and six months ended June 30, 2026, no shares were repurchased. 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.
Issuance of Warrants
On May 6, 2026, in connection with the long-term partnership with a customer to strengthen U.S. manufacturing for AI infrastructure, the Company entered into a securities purchase agreement (the “Purchase Agreement”) under which the Company issued and sold (i) a warrant (the “Traditional Warrant”) to purchase up to 15 million shares of common stock of the Company at an exercise price of $180.00 per share, and (ii) a pre-funded warrant (the “Pre-Funded Warrant” and, together with the Traditional Warrant, the “Warrants”) to purchase up to 3 million shares of common stock at an exercise price of $0.0001 per share.
The Warrants are equity-classified awards and are exercisable at any time on or after the issuance date. The Traditional Warrant will expire on the earliest to occur of (a) the third anniversary of the issuance date, (b) the termination of the definitive agreement governing the long-term partnership, subject to certain exceptions, and (c) the consummation of a fundamental transaction by the Company. The Pre-Funded Warrant will expire on the earlier to occur of (x) the third anniversary of the issuance date and (y) the consummation of a fundamental transaction by the Company.
The Traditional Warrant was issued without separate consideration and does not convey rights to a distinct good or service. Accordingly, it was accounted for as consideration payable to a customer and, as an equity-classified award, was measured at its grant-date fair value of $296 million and recorded within additional paid-in capital on the consolidated balance sheets. Refer to Note 2 (Revenue) for additional information. Because the Traditional Warrant is equity-classified, it is not subsequently remeasured to fair value after issuance.
The grant-date fair value of the Traditional Warrant of $296 million was estimated using a binomial lattice valuation model and Level 3 inputs that incorporated path-dependent features, including potential early exercise and contractual restrictions such as lock-up provisions. Significant assumptions included expected volatility, expected term, risk-free rate and dividend yield. Expected volatility was based on the Company’s historical stock price volatility and, due to its subjective nature, is inherently uncertain. Changes in these assumptions, particularly expected volatility, could have materially affected the estimated grant-date fair value of the Traditional Warrant.
The Pre-Funded Warrant was issued for cash consideration of $500 million, which approximated its fair value at issuance, and recorded within additional paid-in capital on the consolidated balance sheets. In addition, as a result of the nominal exercise price, the underlying common shares are considered outstanding for purposes of calculating earnings per common share.

Reportable Segments

Segment Reporting [Abstract]  
Reportable Segments Reportable Segments
Effective in the first quarter of fiscal 2026, the Company revised its segment structure. This revision corresponds with changes in how our businesses are managed, which align with how our chief operating decision maker (“CODM”) reviews performance and allocates resources. As a result, the Company began managing its Display and Specialty Materials businesses as a single operating segment, referred to as Glass Innovations, and its Hemlock Semiconductor Group, solar wafer, and solar module businesses as a single operating segment, referred to as Solar. In addition, the Company’s Life Sciences business does not meet the quantitative threshold for separate reporting and therefore is no longer reported as a reportable segment and is included together with all other businesses that do not meet the quantitative threshold for separate reporting within Life Sciences and Emerging Growth Businesses. Optical Communications and Automotive remain unchanged and continue to be reported as separate reportable segments.

As a result of the above changes, the Company has determined it has four reportable segments for financial reporting purposes, organized primarily based on product offerings, 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.
•Glass Innovations – utilizes proprietary melting, precision forming, strengthening, and finishing processes to create advanced flat glass substrates for LCD and OLED displays and cover materials for mobile consumer electronics; and provides material formulations and optical fabrication for specialty glass, glass ceramic, fluoride crystal, and other precision materials and components for semiconductor, aerospace and defense, telecommunications, commercial, and industrial applications.
•Automotive – manufactures ceramic substrates and filter products for emissions control systems in mobile applications; as well as technical glass and optic products and solutions for the interior and exterior of vehicles.
•Solar – manufactures silicon materials and products for semiconductor and solar applications, including hyper-pure polysilicon produced by Hemlock Semiconductor Group, solar wafers, and solar modules. The segment’s products serve customers across the semiconductor and solar markets globally from a manufacturing footprint in the United States.

All other businesses that do not meet the quantitative threshold for separate reporting have been grouped as Life Sciences and Emerging Growth Businesses.

These changes reflect the Company’s internal management structure and align with the information regularly reviewed by the CODM.

The 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 corporate 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 assess the performance for each segment.
Financial results for the reportable segments and Life Sciences and Emerging Growth Businesses 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, segment results provided to the CODM include an adjustment for hedged exposures, as defined in more detail below, to adjust for the impact of the Company’s foreign currency risk management program with respect to certain foreign currency exchange rate movements. Segment results also exclude specific items, detailed below, that are non-recurring or otherwise unrelated to the Company’s ongoing operations.
Items excluded from segment results include realized and unrealized gains and losses on our undesignated foreign exchange forward or option contracts and cross-currency swaps, which we refer to as our translated earnings contracts, and on the translation of our foreign-denominated debt. Other excluded items include 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 that do not reflect the ongoing operating results of the Company. These items are included in the unallocated amounts in the reconciliation of reportable segment net income to consolidated net income and are not used by the CODM in allocating resources or evaluating the results of the segments. 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 certain of 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 to consolidated net income.
Segment net income may not be consistent with measures used by other companies.
Prior to April 1, 2026, segment results included an adjustment that utilized long-term management-determined core rates, which were used in our presentation of the “constant-currency adjustment.” These core rates were applied to all foreign currency exposures for which we were significantly hedged during the applicable period, even though we may have been less than 100% hedged.
Effective April 1, 2026, we prospectively replaced constant-currency reporting with a new adjustment to derive our segment results, which we refer to as our “adjustment for hedged exposures” as discussed in more detail below. The prior constant-currency adjustment and the current adjustment for hedged exposures are distinct adjustments determined using different methodologies.
Because a significant portion of the Company’s revenues and expenses are denominated in currencies other than the U.S. dollar, the Company maintains a foreign currency risk management program whereby it hedges its foreign currency exposure to the Japanese yen, Mexican peso, Chinese yuan, South Korean won, euro and New Taiwan dollar. Management utilizes the adjustment for hedged exposures for the Optical Communications, Glass Innovations and Automotive segments to reflect the Company’s foreign currency risk management program with respect to these currencies, as applicable to each segment. The most significant adjustment relates to the Japanese yen exposure within the Glass Innovations segment.
The adjustment for hedged exposures is calculated by applying our hedge rates (as defined below) to the portion of foreign currency exposure that is hedged by the Company’s hedging instruments during the applicable period. These hedging instruments include our translated earnings contracts and non-derivative instruments such as foreign-denominated debt. The identification of hedged exposures is consistent with the Company’s documented foreign exchange risk management practices. The remaining portion of foreign currency exposure that is not hedged is not adjusted and continues to be reflected at the exchange rates used in the Company’s consolidated GAAP results during the applicable period. The currency rates used in calculating this adjustment for hedged exposures (our “hedge rates”) reflect the weighted average of the contractual exchange rates of the Company’s hedging instruments in place for foreign currency exposure for the applicable period. The realized and unrealized gains or losses from our translated earnings contracts and non-derivative instruments are excluded from our segment results and we include the adjustment for hedged exposures to reflect the underlying hedge rates related to these hedging instruments. The adjustment for hedged exposures, when applied to net sales, reflects only the impact of foreign currency exchange rate movements on the hedged portion of exposure.
The table below presents the hedge rates used in calculating the adjustment for hedged exposures for the three months ended June 30, 2026 as well as the percentage of exposure hedged for the same period. Percentages are calculated relative to after-tax earnings exposure.

The table below presents the rates that were used in calculating the constant-currency adjustment and were applied to all foreign exchange exposures during the three months ended March 31, 2026 and the three and six months ended June 30, 2025, even though we may have been less than 100% hedged:

Segment results for the comparative prior period as presented herein are the amounts as historically reported and adjusted only for the changes in segment reporting structure as described above. The prior constant-currency adjustment and the current adjustment for hedged exposures are distinct non-GAAP adjustments determined using different methodologies and reflect different foreign currency hedging approaches in the periods presented. Prior-period amounts have not been recast to the current-period presentation. Application of the current adjustment for hedged exposures in place of the prior constant-currency adjustment for the comparative 2025 periods would have resulted in higher year-over-year growth rates for segment net sales and segment net income for our Glass Innovations segment for the three and six months ended June 30, 2026. The impact to segment net sales and segment net income for all other segments would have been immaterial.
The following provides selected segment information. The comparative periods have been recast for the changes in the reportable segment structure, as described above. However, periods prior to April 1, 2026 have not been recast for the changes in the segment measures, as described above.

Principles of Consolidation
The consolidated financial statements include the accounts of Corning Incorporated and its consolidated subsidiaries (collectively, the “Company”), consisting of its wholly-owned subsidiaries, partially-owned subsidiaries in which the Company holds a controlling financial interest through ownership of a majority of the voting interests and those entities in which the Company has a variable interest and of which the Company is 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 balances, 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, 2025 (“2025 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 related disclosures of contingent assets and liabilities on 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.
