Corning Announces Strong First-Quarter 2025 Financial Results (1)

CORNING, N.Y. — Corning Incorporated (NYSE: GLW) today announced its first-quarter 2025 results and provided its outlook for second-quarter 2025.

Wendell P. Weeks, chairman and chief executive officer, said, “Today, we announced strong first-quarter results that exceeded guidance. Core sales grew 13% year over year and core EPS grew three times faster. In Optical Communications, sales in our Enterprise business were up 106% year over year on continued strong demand for our new products for Gen AI.”

Weeks continued, “We remain confident in our ability to deliver our Springboard plan. We’re well positioned to maintain momentum despite a dynamic external environment because our growth is underpinned by powerful secular trends that are underway today. For example, we’re seeing remarkable customer response to both our innovations for Gen AI data centers and our U.S.-made solar products, and we are accelerating our production ramps for both.”

Ed Schlesinger, executive vice president and chief financial officer, said, “In the first quarter, we continued to improve our return profile. Year over year, core sales grew 13%, core EPS was up 42%, and we expanded operating margin 250 basis points and core ROIC 300 basis points. Our momentum is strong. In the second quarter, we expect to grow core sales to approximately $3.85 billion and to again grow core EPS significantly faster than sales to a range of $0.55 to $0.59. Our guidance factors in about $0.01 to $0.02 for the impact of currently enacted tariffs, along with $0.03 of temporarily higher cost as we ramp to meet increased demand for our Gen AI and solar products.”

First-Quarter 2025 Financial Highlights:

•GAAP sales were $3.45 billion. Core sales were $3.68 billion.

•GAAP EPS was $0.18. Core EPS was $0.54. The difference between GAAP and core EPS primarily reflected mainly non-cash, mark-to-market adjustments associated with the company’s translated earnings contracts and Japanese-yen-denominated debt and also reflected constant currency adjustments.

•GAAP gross margin was 35.2%. Core gross margin was 37.9%, reflecting 180-basis-point and 110-basis-point year-over-year improvements, respectively.

Second-Quarter 2025 Outlook:

•In the second quarter, management expects core sales of approximately $3.85 billion and core EPS to again grow significantly faster than sales to a range of $0.55 to $0.59; the guidance factors $0.01 to $0.02 for currently enacted tariffs, along with $0.03 of temporarily higher costs associated with production ramps to meet increased demand for Gen AI and solar products.

First-Quarter 2025 Results and Comparisons

(1)Core performance measures are non-GAAP financial measures. The reconciliation between GAAP and non-GAAP measures is provided in the tables following this news release as well as on the company’s website.

In Optical Communications, first-quarter sales were $1.36 billion, up 46% year over year, primarily driven by continued strong adoption of Corning’s new Gen AI products in the Enterprise portion of the business, which was up 106%. First-quarter net income was $201 million, up 101% year over year, driven by strong incremental profit on the higher volume.

In Display, first-quarter sales were $905 million, up 4% year over year, driven by volume and price increases. Net income was $243 million. Beginning in the first quarter, the company changed the Japanese yen constant-currency rate to 120 yen from 107 yen, to align with its new hedging instrument rates. Prior-year results are not recast and remain at 107 yen.

In Specialty Materials, first-quarter sales were $501 million, up 10% year over year, driven by continued strong demand for premium glass for mobile devices. Net income was $74 million, up 68% year over year.

In Automotive, first-quarter sales were $440 million, and net income was $68 million, both consistent with the previous quarter, primarily reflecting continued softness in European and North American light- and heavy-duty markets. As of Jan. 1, 2025, the company moved its Automotive Glass Solutions business out of Hemlock and Emerging Growth Businesses to be managed along with Environmental Technologies in a newly formed Automotive segment.

Prior-period results have been recast for comparison purposes.

In Life Sciences, first-quarter sales were $234 million, down 1% year over year. Net income was $13 million.

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.

The following table sets forth the computation of basic and diluted earnings per common share:

The following table sets forth the computation of core earnings per share:

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 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, Optical Communications, 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 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, please see 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, please see “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.

(a)Based upon statutory tax rates in the specific jurisdiction for each event.

(b)The calculation of the effective tax rate (“ETR”) for GAAP and Core excludes net income attributable to non-controlling interest (“NCI”) of approximately $28 million and $29 million, respectively.

(a)Based upon statutory tax rates in the specific jurisdiction for each event.

(b)The calculation of the ETR for GAAP and Core excludes net income attributable to NCI of approximately $16 million and $17 million, respectively.

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 March 31, 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) income, net in the consolidated statements of income was $(1) million and $6 million for the three months ended March 31, 2025 and 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 20.2% for the three months ended March 31, 2025 and 2024, respectively.

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, Optical Communications, Specialty Materials, Automotive and Life Sciences segments for the Japanese yen, 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 months ended March 31, 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 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. 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:

(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.

(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, 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)Loss on investments: Amount reflects the 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.

(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.
