Wendell P. Weeks, chairman, chief executive officer, and president, said, “In the second quarter, we delivered outstanding results, and T4we upgraded our Springboard Plan to grow sales to an annualized run rate of $20 billion by the end of 2026, $30 billion by the end of 2028, and $40 billion by the end of 2030. We’re entering a new phase of accelerating growth, and we expect to deliver a sales CAGR of 19% from Q4 2026 to Q4 2030 – while growing earnings faster than sales, with significantly higher returns on invested capital and substantially more free cash flow.”

Weeks continued, “We continue to deepen our long-term customer partnerships with industry leaders, most recently with Amazon and NVIDIA. These partnerships provide strong proof points supporting our exciting Springboard Plan.”

Ed Schlesinger, executive vice president and chief financial officer, said, “In the second quarter, we delivered our ninth consecutive quarter of year-over-year growth and continued to enhance our financial profile. We grew core sales 17% to $4.74 billion and core EPS 30% to $0.78. T5We expanded core gross margin 120 basis points to 39.6% and core operating margin 190 basis points to 20.9%. T6We also grew core ROIC 180 basis points to 14.9% and delivered strong adjusted free cash flow of $1.42 billion.”

Schlesinger continued, “In the third quarter, we expect core sales to grow approximately 16% year over year to a range of $4.9 billion to $5 billion and core EPS to grow about 28% year over year to a range of $0.85 to $0.89. We also expect an improving impact on earnings from Solar starting in Q3 as our ramp continues, building toward a revenue stream of more than $3 billion with strong profit and cash flow. Overall, we are off to a great start on our upgraded Springboard plan to capture a new phase of accelerating growth.”

Second-Quarter 2026 Financial Highlights:

•GAAP sales were $4.51 billion, up 17% year over year. Core sales were $4.74 billion, up 17% year over year.

•GAAP EPS was $0.64, up 19% year over year. Core EPS was $0.78, up 30% year over year. The difference between GAAP and core EPS principally reflects adjustments for hedged exposures, along with largely non-cash discrete tax items and restructuring and impairment charges. A complete quantitative reconciliation of these and other reconciling items appears in the tables accompanying this release.

•GAAP gross margin was 36.1%. Core gross margin expanded 120 basis points to 39.6%.

•GAAP operating margin was 15.5%. Core operating margin expanded 190 basis points to 20.9%.

•GAAP operating cash flow was $1.72 billion, and adjusted free cash flow was $1.42 billion.

Third-Quarter 2026 Outlook:

•In the third quarter, management expects core sales to grow approximately 16% year over year to a range of $4.9 billion to $5 billion and core EPS to grow approximately 28% year over year to a range of $0.85 to $0.89.

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

Management uses non-GAAP financial measures (our “core performance measures”), together with GAAP financial measures, to evaluate operating performance, make financial and operational decisions, and allocate resources. Management believes that core performance measures, when considered together with the Company’s GAAP results, provide investors with useful supplemental information by facilitating a functional view of operating results and providing additional insight into factors and trends affecting the Company’s performance.

Specifically, in managing the Company and assessing our financial performance, we supplement certain measures included in our consolidated financial statements by excluding specific items and making certain adjustments to arrive at our core performance measures. These measures are intended to supplement, and should not be viewed as a substitute for, the Company’s GAAP financial measures.

Items excluded from certain core performance measures 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.

Prior to April 1, 2026, we included an adjustment to derive our core performance measures 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 non-GAAP adjustment, 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 non-GAAP 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. Management believes that this adjustment for hedged exposures is useful for analyzing underlying business trends and establishing operational goals and forecasts by illustrating results aligned with the currency environment established by the Company’s foreign currency risk management program.

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 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 core performance measures in our GAAP to core reconciliation, 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

Management believes the adjustment for hedged exposures provides investors with useful supplemental information regarding operating performance by reflecting the effect of the Company’s foreign currency risk management program on the portion of exposure actually hedged during the applicable period.

Core performance measures for the comparative prior period as presented herein are the amounts as historically reported. 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 core net sales, core net income and core earnings per share for the three and six months ended June 30, 2026.

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 (losses) 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 June 30, 2026 and 2025 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 was a loss of $5 million and $11 million for the three months ended June 30, 2026 and June 30, 2025, 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 hedged exposures reporting for the three months ended June 30, 2026 and an adjustment for constant currency reporting for the three months ended June 30, 2025, as described within “Core Performance Measures.” For the three months ended June 30, 2025, the difference also included an adjustment of $12 million for restructuring charges associated with an affiliated company as described within the “Reconciliation on non-GAAP Measures.”

(3)Income tax amounts are calculated based on the core effective tax rate of 18.5% and 19.5% for the three months ended June 30, 2026 and June 30, 2025, respectively.

Items Adjusted from GAAP Measures

Items adjusted from GAAP measures to arrive at core performance measures are as follows:

(1)Adjustment for hedged exposures: Effective April 1, 2026, the Company replaced its prior constant-currency adjustment with an adjustment for hedged exposures. 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 exposure to the Japanese yen, Mexican peso, Chinese yuan, South Korean won, euro and New Taiwan dollar. Management uses the adjustment for hedged exposures for the Optical Communications, Glass Innovations and Automotive segments to reflect the impact of that program, as applicable to each segment. The most significant adjustment relates to Japanese yen exposure within the Glass Innovations segment, which primarily impacts net sales.

The prior constant-currency adjustment and the current adjustment for hedged exposures are distinct non-GAAP adjustments determined using different methodologies. Under the prior methodology, management-determined 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. Under the current adjustment for hedged exposures, contractual hedge rates are applied only to the portion of exposure actually hedged during the applicable period, and the remaining unhedged exposure is reflected at the exchange rates included in the Company’s consolidated GAAP results. The prior-period amounts presented herein are the amounts as historically reported.

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.

(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, Mexican peso, Chinese yuan, South Korean won, euro and New Taiwan dollar 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)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.

(9)Gain or loss on sale of business: Amount reflects the gain or loss recognized for the sale of a business, recorded in other expense, net, on the consolidated statements of income.

(10)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.

(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.

(12)Equity in losses of affiliated companies: Amount reflects costs not related to continuing operations of affiliated companies, such as restructuring, impairment losses, inventory adjustments, and other charges and credits.
