CORNING, N.Y. — Corning Incorporated (NYSE: GLW) today announced its third-quarter 2025 results and provided its outlook for fourth-quarter 2025.
Wendell P. Weeks, chairman and chief executive officer, said, “We delivered another excellent quarter. Year over year, core sales grew 14% to $4.27 billion, and core EPS grew 24% to $0.67. Overall, as we approach the second anniversary of Springboard, the plan has been a tremendous success. We have added $4 billion to our annualized sales run rate, and we have significantly improved our profitability – with an expected operating margin of 20% in the fourth quarter, a year ahead of plan.”
Weeks continued, “Beyond our strong third-quarter performance, we see significant growth ahead, fueled by powerful secular trends. To share just a few examples, we are ramping to meet remarkable demand for both our new Gen AI and U.S.-made solar products, and Apple’s recent $2.5 billion commitment to produce 100% of iPhone and Apple Watch cover glass at our Kentucky facility creates a larger, longer-term opportunity.”
Ed Schlesinger, executive vice president and chief financial officer, said, “Our outstanding third-quarter results reflect sales growth and margin expansion across multiple businesses. Year over year, core sales grew 14% while core operating margin expanded 130 basis points to 19.6%, core EPS grew 24%, and core ROIC grew 160 basis points to 13.4%. Additionally, we delivered strong adjusted free cash flow of $535 million. Overall, we continue to significantly enhance our returns as we execute Springboard.”
Schlesinger continued, “We expect continued strong growth in the fourth quarter, driven by ongoing robust demand for our Gen AI products and sales of solar wafers. We're guiding to core sales of approximately $4.35 billion, with core EPS growing faster than sales to a range of $0.68 to $0.72. Additionally, we are on track to achieve our Springboard operating margin target of 20% in the fourth quarter, a year ahead of plan. This represents a 370-basis-point improvement from our Q4-2023 starting point – and establishes a strong return profile as we continue to grow sales.”

•GAAP sales were $4.10 billion. Core sales were $4.27 billion.

Presentation of Information in this News Release
This news release includes non-GAAP financial measures. Non-GAAP financial measures are not in accordance with, or an alternative to, GAAP. Corning’s non-GAAP financial measures exclude the impact of items that are driven by general economic conditions and events that do not reflect the underlying fundamentals and trends in the company’s operations. The company believes presenting non-GAAP financial measures assists in analyzing financial performance without the impact of items that may obscure trends in the company’s underlying performance. Definitions of these non-GAAP financial measures and reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures can be found on the company’s website by going to the Investor Relations page and clicking “Quarterly Results” under the “Financials and Filings” tab. These reconciliations also accompany this news release.
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.

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 measures that are not calculated in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and exclude specific items that are non-recurring, related to foreign exchange volatility, or unrelated to continuing operations. These measures are our core performance measures.
Management uses core performance measures, along with GAAP financial measures, to make financial and operational decisions and certain of these measures also form the basis of our compensation program metrics. Management believes that our core performance measures are indicative of our core operating performance and provide investors with greater visibility into how management evaluates our results and trends and makes business decisions. These measures are not, and should not be viewed as a substitute for, GAAP reporting measures.
Items that are excluded from certain core performance calculations include: the impact of translating the 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 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 Optical Communications, Display, Specialty Materials, Automotive and Life Sciences segments to exclude the impact from the Japanese yen, South Korean won, Chinese yuan, New Taiwan dollar, Mexican peso and euro, as applicable to the segment. The most significant constant-currency adjustment relates to the Japanese yen exposure within the Display segment. The constant-currency rates established for our core performance measures are long-term management-determined rates, 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.
For a reconciliation of non-GAAP performance measures to their most directly comparable GAAP financial measure, refer to “Reconciliation of Non-GAAP 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.

Core return on invested capital (“core ROIC”) is a non-GAAP measure used by management and can be used by investors to review our investment and capital allocation decisions. We define core ROIC as the after-tax core operating income, inclusive of core equity earnings from affiliated companies, as a percentage of invested capital, calculated as total equity plus total long-term debt. Core ROIC for the three months ended September 30, 2025 and 2024 is calculated by annualizing the after-tax return for the respective period.

(1)Refer to the reconciliation of operating income as reported in our GAAP results to core operating income within the “Reconciliation of non-GAAP measures.”
(2)Equity earnings in affiliated companies as reflected within other expense, net in the consolidated statements of income (loss) was $1 million and $2 million for the three months ended September 30, 2025 and September 30, 2024, respectively. The difference between equity earnings in affiliated companies as reported in our GAAP results and as reflected as a non-GAAP core performance measure is an adjustment for constant currency reporting, as described within “Core Performance Measures.”
(3)Income tax amounts are calculated based on the core effective tax rate of 19.5% and 19.1% for the three months ended September 30, 2025 and September 30, 2024, respectively.

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 Optical Communications, Display, Specialty Materials, Automotive and Life Sciences segments for the Japanese yen, South Korean won, Chinese yuan, New Taiwan dollar, Mexican peso and euro, as applicable to the segment. 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. For the three and nine months ended September 30, 2025 and 2024, the constant-currency adjustment primarily relates to our Japanese yen exposure due to the difference in the average spot rate compared to our core rate.
The constant-currency rates established for our core performance measures are long-term management-determined rates, 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. 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 period presented and to all foreign exchange exposures during the period, even though we may be less than 100% hedged:

Korean won
Chinese yuan
New Taiwan dollar

(2)Translation of foreign denominated debt, net: Amount reflects the gain or loss on the translation of our yen-denominated and euro-denominated debt to U.S. dollars, net of gains or losses on related hedging instruments.
(3)Translated earnings contract, net: Amount reflects the impact of the realized and unrealized gains and losses from the Japanese yen, South Korean won, Chinese yuan, New Taiwan dollar, Mexican peso and euro-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 of a foreign entity, which are not related to ongoing operations.
(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)Gain or loss on investments: Amount reflects the gain or loss recognized on investments due to mark-to-market adjustments for the change in fair value or the disposition of an investment.
(10)Loss on sale of assets: Amount represents the loss recognized for the sale of assets, recorded in cost of sales, in the consolidated statements of income (loss).
(11)Equity in losses of affiliated companies: Amount reflects costs not related to continuing operations of affiliated companies, such as restructuring, impairment losses, inventory adjustments, other charges and credits.
(12)Loss on sale of business: Amount reflects the loss recognized for the sale of a business, recorded in other expense, net in the consolidated statements of income (loss).
