Corning Announces Strong First-Quarter 2026 Financial Results (1)


CORNING, N.Y. — Corning Incorporated (NYSE: GLW) today announced its first-quarter 2026 results and provided its outlook for second-quarter 2026.
News Summary:
First-quarter core sales grew 18% to $4.35 billion, and core EPS grew 30% to $0.70 versus Q1-2025.
Robust demand for Gen AI products and the ramp of new solar products drove Q1 growth.
Optical Communications sales grew 36%, and Solar sales were up 80% year over year.

Two additional hyperscale customers entered into large, long-term agreements with Corning.
Deals are similar in size and duration to the recently announced multiyear, up-to-$6 billion agreement with Meta.
Agreements highlight customers’ commitment to develop, innovate, and manufacture the critical technologies that power next-generation AI data centers in the United States.

Corning plans to upgrade and extend its Springboard plan through 2030 and introduce a new Market-Access Platform at the company’s May 6 NYC investor event.
Optical Communications new Photonics Market-Access Platform will serve Gen AI OEM customers.

For the second quarter, management expects to grow core sales about 14% year over year to approximately $4.6 billion and core EPS about 25% year over year to a range of $0.73-$0.77.
Second-quarter guidance includes an extended maintenance shutdown at Corning’s solar wafer facility, including the transition to a permanent power system while the company repairs, upgrades, and modifies production equipment to increase throughput in future quarters. This will cause an additional $30 million of expense in Q2 versus Q1 and is included in guidance.


(1) First-quarter GAAP results: Sales were $4.14 billion, gross margin was 36.9%, operating margin was 15.4%, EPS was $0.43, and operating cash flow was $362 million.

Wendell P. Weeks, chairman, chief executive officer, and president, said, “Our strong first-quarter results continued the powerful trajectory of our Springboard plan. Versus Springboard’s Q4-2023 starting point, we grew core sales 33% and core EPS 79%, and we expanded core operating margin and core ROIC by 390 basis points and 470 basis points, respectively. Additionally, we finalized two more hyperscaler deals similar in size and duration to our recently announced multiyear, up-to-$6 billion agreement with Meta. In total, we have powerful momentum across our Market-Access Platforms.”

Weeks continued, “Based on strong demand for our innovations, we plan to upgrade and extend our Springboard plan through 2030 at our May 6 investor event. We will introduce our new Photonics Market-Access Platform and explain the underlying technical and demand trends driving our Gen AI product development.”

Ed Schlesinger, executive vice president and chief financial officer, said, “Our first-quarter results show continued excellent performance on our Springboard plan. We delivered our eighth consecutive quarter of year‑over‑year growth, with core sales up 18% led by Optical Communications and our new Solar business, which was up 80%. Our solar ramp continues with our polysilicon business performing above our 20% corporate operating margin target in the first quarter, and our module business is on track to cross over in the second quarter. We continued to enhance the company's financial profile, growing core EPS 30% year over year, while expanding core operating margin 220 basis points, core gross margin 120 basis points, and core ROIC 190 basis points.”

Schlesinger continued, “In the second quarter, we expect to grow core sales about 14% year over year to approximately $4.6 billion and to grow core EPS about 25% year over year to a range of $0.73 to $0.77. We have built into our second-quarter forecast an extended maintenance shutdown at our solar wafer facility, including the transition to a permanent power system while we repair, upgrade, and modify our production equipment to increase throughput in future quarters. This will cause an additional $30 million of expense versus the first quarter.”

First-Quarter 2026 Financial Highlights:
GAAP sales were $4.14 billion, up 20% year over year. Core sales were $4.35 billion, up 18% year over year.
GAAP EPS was $0.43, up 139% year over year. Core EPS was $0.70, up 30% year over year. Differences between GAAP and core EPS include constant currency adjustments as well as primarily non-cash items, including acquisition-related costs; discrete tax items and other tax-related adjustments; and restructuring, impairment, and other charges and credits.
GAAP gross margin was 36.9%. Core gross margin expanded 120 basis points to 39.1%.
GAAP operating margin was 15.4%. Core operating margin was 20.2%.
GAAP operating cash flow was $362 million, and adjusted free cash flow was $188 million.

Second-Quarter 2026 Outlook:
For the second quarter, management expects to grow core sales about 14% year over year to approximately $4.6 billion and core EPS about 25% year over year to a range of $0.73-$0.77.
Second-quarter guidance includes an extended maintenance shutdown at Corning’s solar wafer facility, including the transition to a permanent power system while the company repairs, upgrades, and modifies production equipment to increase throughput in future quarters.

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 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, Glass Innovations and Automotive 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 Glass Innovations 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, cross-currency swaps 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 March 31, 2026 and 2025 is calculated by annualizing the after-tax return for the respective period.

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, Glass Innovations and Automotive 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 months ended March 31, 2026 and 2025, 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, cross-currency swaps and foreign-denominated debt.

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 may be less than 100% hedged:
CurrencyJapanese yenKorean wonChinese yuanNew Taiwan dollarMexican pesoEuro
Rate¥120₩1,250¥6.9NT$31MX$21€0.88
(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 derivative instruments.
(3)Translated earnings contract, net: Amount reflects the impact of the realized and unrealized gains and losses on our derivative instruments used to hedge Japanese yen, South Korean won, Chinese yuan, New Taiwan dollar, Mexican peso and euro foreign currency exposure related to translated earnings.
(4)Acquisition-related costs: Amount reflects intangible amortization, inventory valuation adjustments, contingent consideration 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, changes in deferred tax asset valuation allowances and stock compensation windfall or shortfall, 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)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.
(8)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.
(9)Gain or loss on sale of assets: Amount represents the gain or loss recognized for the sale of assets, recorded in cost of sales, on the consolidated statements of income.
(10)Loss on sale of business: Amount reflects the loss recognized for the sale of a business, recorded in other expense, net, on the consolidated statements of income.
(11)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.
