(Unaudited)

1. 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 consolidated accounts of Corning Incorporated and its subsidiaries 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, which include 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 Form10-K for the year ended* December 31, 2023* (“2023 Form10-K”). The results of operations for the interim periods arenot 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 related 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 reported in future periods* may*be different from these estimates.

The non-controlling interest as recorded in the consolidated financial statements represents amounts attributable to the minority shareholders of Hemlock Semiconductor Group (“HSG”) and other less-than-wholly-owned consolidated subsidiaries.

Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications hadno material impact on the results of operations, financial position or changes in shareholders’ equity.

3. Revenue

Disaggregated Revenue

The following table presents revenues by product category (in millions):

Customer Deposits

As of* September 30, 2024* and* December 31, 2023*, Corning had customer deposits of approximately $1.2 billion. Most of these customer deposits were non-refundable and allowed customers to secure rights to products produced by Corning under long-term supply agreements, generally over a period of up toten years. As products are delivered to customers, Corning will recognize revenue and reduce the amount of the customer deposit liability.

For thethree months ended* September 30, 2024and2023*, customer deposits recognized were $36 million and $6 million, respectively. For thenine months ended* September 30, 2024and2023*, customer deposits recognized were $127 million and $88 million, respectively.

Refer to Note7 (Other Liabilities) for additional information.

Deferred Revenue

As of* September 30, 2024* and* December 31, 2023*, Corning had deferred revenue of approximately $883 million and $860 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 thethree andnine months ended* September 30, 2024* and2023, the amount of deferred revenue recognized in the consolidated statements of (loss) income wasnot material.

4. Income Taxes

The following table presents the provision for income taxes and the related effective tax rate (in millions, except percentages):

For thethree months ended* September 30, 2024*, the effective tax rate differed from the United States (“U.S.”) statutory rate of 21%, primarily due to certain pre-tax losses withno corresponding expected tax benefit, changes in estimates based on the final2023 U.S. Federal Income Tax Return, and the impact of foreign exchange losses. For thenine months ended* September 30, 2024,the effective tax rate differed from the U.S. statutory rate of 21%, primarily due to certain pre-tax losses withno* corresponding expected tax benefit.

For thethree months ended* September 30, 2023*, the effective tax rate differed from the U.S. statutory rate of 21%, primarily due to differences arising from foreign earnings partially offset by changes in estimates based on the final2022 U.S. Federal Income Tax Return. For thenine months ended* September 30, 2023,the effective tax rate differed from the U.S. statutory rate of 21%, primarily due to differences arising from foreign earnings, changes in estimates based on the final2022* U.S. Federal Income Tax Return and adjustments related to share-based compensation, partially offset by changes in valuation allowance assessments.

Corning Precision Materials, a South Korean subsidiary, is currently appealing certain tax assessments and tax refund claims for tax years2010 through2019. 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. During thesecond quarter of2023, $99 million wasno longer under dispute and was refunded to the Company. The non-current receivable balance was $265 million and $261 million as of* September 30, 2024and December 31, 2023*, respectively, for the amount on deposit with the South Korean government. Corning believes that it is more likely thannot the Company will prevail in the appeals process relating to these matters.

11. 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 Chapter11 Related Matters**

Until* June1,* 2016, Corning and The Dow Chemical Company (“Dow”) each owned 50% of the common stock of Dow Corning Corporation (“Dow Corning”). On* May31,* 2016, Corning and Dow realigned their ownership interest in Dow Corning. Following the realignment, Corningno longer owned any interest in Dow Corning. With the realignment, Corning agreed to indemnify Dow for 50% of Dow Corning’s non-ordinary course, pre-closing liabilities to the extent such liabilities exceed the amounts reserved for them by Dow Corning as of* May**31,* 2016, subject to certain conditions and limits. In* January 2024,we entered into an agreement to settle the Dow Corning Chapter11* Related Matters and the settlement amount wasnot material.

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 maybe required to indemnify Dow for up to 50% of such losses. As of September 30, 2024*, Corning has determined a potential liability for these environmental matters is probable and the amount reserved wasnot material.

Environmental Litigation

Corning has been designated by federal or state governments under environmental laws, including Superfund, as a potentially responsible party that* maybe liable for cleanup costs associated with 19 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 September 30, 2024* and* December 31, 2023*, Corning had accrued approximately $81 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.

Cross Currency Swap Contracts

Since inception of the Company’s Japanese yen-denominated debt, the Japanese yen has weakened and the US dollar value of these liabilities has decreased, generating unrealized foreign exchange gains that have been recognized over time in the consolidated statements of (loss) income. In thesecond quarter of2024, to economically lock in unrealized foreign exchange gains, the Company entered into a¥23 billion, or $215 million, fixed rate, three-year cross currency swap contract relating to a portion of the Company’s Japanese yen-denominated debt due in2027. At inception of this instrument, Corning received a net $68 million from the counterparty, representing an exchange of the notional amounts at a fixed foreign exchange rate of Japanese yen to US dollar and was initially recorded as a derivative liability. As of* September 30, 2024*, the fair value of this derivative liability is $64 million.

Net Investment Hedges

In* May 2023,the Company designated the full amount of its euro-denominated2026* Notes and2031 Notes with a total notional amount of€850 million, which are non-derivative financial instruments, as net investment hedges against our investments in certain European subsidiaries with euro functional currencies. As of* September 30, 2024*, the net investment hedges are deemed to be effective. During thethree andnine months ended* September 30, 2024*, foreign currency losses of $39 million and $9 million, respectively, associated with these net investment hedges were recognized in other comprehensive income (loss).

15. Reportable Segments

The Company has determined that it hasfive reportable segments for financial reporting purposes, as follows:

All other businesses that donot 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, Auto Glass Solutions and the Emerging Innovations Group.

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. 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 Display Technologies, Specialty Materials, Environmental Technologies 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 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 werenot* recast as the impact wasnot material. The most significant constant-currency adjustment relates to the Japanese yen exposure within the Display Technologies segment.

18

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* mayinclude, but arenot* limited to, foreign exchange forward or option contracts and foreign-denominated debt. The Company believes that the use of constant-currency reporting allows management to understand segment 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, even though we* maybe less than100%* hedged:

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 (loss) income attributable to Corning Incorporated. These items arenot used by the CODM in allocating resources or evaluating the results of the segments and include the following: 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 non-recurring non-operational items. 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 arenot allocated to the segments are included in the reconciliation of reportable segment net income (loss) to net (loss) income attributable to Corning Incorporated. Segment net income (loss)* may**not* be consistent with measures used by other companies.
