GLW Corning Inc. 10-Q 2026-09-30 section summaries

Corning (GLW) — Q3 and 9M 2026

Consolidated results

Q3 gross margin was 37.3% of sales, compared with 37.1%. Operating expenses included SG&A of $563 million versus $624 million, R&D of $314 million versus $280 million, and purchased-intangible amortization of $22 million versus $27 million. Translated-earnings contract gains were $138 million in Q3 versus $33 million, materially contributing to earnings; 9M gains were $212 million versus $63 million. 9M interest expense was $273 million versus $243 million.

Q3 revenue by product category

Optical communications was the largest growth contributor; electronics glass and advanced optics declined. Corning recast prior-year product classifications to match its 2026 reporting structure.

Q3 segment performance

Segment net income is Corning’s measure for evaluating segment performance and allocating resources; it includes different allocations of shared costs and excludes certain items included in consolidated results.

Optical Communications and Solar led sales growth, while Glass Innovations sales and segment earnings declined. Effective in 2026, Corning reorganized reporting into Optical Communications, Glass Innovations, Automotive, and Solar; Life Sciences is reported with Emerging Growth Businesses. From April 1, Corning also replaced its prior constant-currency segment adjustment with an adjustment for hedged exposures. Because 2025 comparatives were not recast, results are not directly comparable; applying the new method to 2025 would have shown higher Glass Innovations sales and net-income growth.

Segment results reconcile to consolidated results through unallocated items. In Q3, the $892 million of segment net income including Life Sciences/Emerging Growth was affected principally by a $(216) million hedged-exposure adjustment, $138 million of translated-earnings contract gains, $(49) million of net interest expense, $(32) million of R&D expense, $(22) million of intangible amortization, and a $32 million income-tax benefit. Q3 2025 included a $(157) million constant-currency adjustment, $33 million of translated-earnings contract gains, $(62) million of net interest expense, and a $127 million tax benefit, among other items. The 9M 2026 reconciliation included $(424) million of hedged-exposure and $(180) million of pre-April constant-currency adjustments, $212 million of translated-earnings contract gains, $(123) million of restructuring, impairment and other charges, and a $321 million tax benefit.

Cash flow and investment

Cash flow included $639 million of customer deposits and government incentives, compared with a $49 million outflow in 9M 2025; inventory growth used $571 million versus $266 million. Financing included $961 million of debt repayments, $449 million of debt and short-term borrowing proceeds, $757 million of dividends, and $500 million of warrant proceeds. Cash and restricted cash increased $985 million during 9M, versus a $120 million decrease in 2025. Period-end cash and cash equivalents were $2.537 billion, or $2.551 billion including restricted cash.

Balance sheet, funding and equity

Long-term debt fair value was $6.5 billion versus carrying value of $7.3 billion; at year-end 2025, fair value was $7.3 billion versus carrying value of $7.6 billion. Corning’s $1.5 billion unsecured revolving facility was undrawn. Yuan-denominated variable-rate facilities totaled $539 million, including $497 million due within one year, at rates of 2.2%–2.9%; balances were $384 million at year-end 2025.

On May 6, Corning issued warrants tied to a long-term customer partnership intended to strengthen U.S. manufacturing for AI infrastructure: a warrant for up to 15 million shares at $180 per share and a pre-funded warrant for up to 3 million shares at $0.0001 per share. The traditional warrant was recorded as $296 million payable to a customer and credited to additional paid-in capital; the pre-funded warrant raised $500 million in cash, and its underlying shares count as outstanding for EPS. Diluted weighted-average shares were 871 million in Q3 and 870 million in 9M. Corning established a $2 billion at-the-market equity program in September but had issued no shares under it by quarter-end. No shares were repurchased; approximately $3.0 billion remained under the $5.0 billion repurchase authorization. Issued shares, rounded, were 1.8 billion at December 31, 2025 and 1.9 billion at September 30, 2026; treasury shares were 992 million and 994 million, respectively. Dividends of $0.28 per share were paid in each of the first three quarters, with another $0.28 declared for December.

A long-term supply agreement through December 31, 2029 included a $1.0 billion customer deposit, partly offset by a $267 million customer warrant whose fair value will reduce revenue as sales occur. Contract liabilities rose to $2.7 billion from $2.3 billion, supporting product access while creating future delivery and revenue-recognition obligations. Solar expansion also involved $253 million of commenced Hemlock equipment finance-lease assets, reduced by $84 million of Section 48D credits; a further $329 million of primarily Hemlock equipment leases had not commenced, with estimated future credits of approximately $98 million.

Other exposures and developments

Derivative notional amounts were $23.429 billion at September 30, 2026, versus $17.063 billion at year-end 2025; fair-value assets were $1.103 billion versus $805 million and liabilities were $802 million versus $466 million. Translated-earnings contracts accounted for much of the notional increase, rising to $18.802 billion from $10.816 billion. Q3 gains on undesignated derivatives were $176 million versus a $13 million loss; 9M gains were $191 million versus $146 million. These results included noncash pre-tax realized losses on expired option premiums of $74 million in Q3 and $239 million in 9M, compared with $94 million and $202 million in 2025. Euro-denominated debt designated as a net-investment hedge had a $622 million equivalent notional, down from $881 million. Derivative fair values use Level 2 inputs.

The Q3 income-tax provision was $222 million versus $80 million; effective tax rates were 22.9% and 14.5%. The 9M provision was $383 million versus $219 million, with effective rates of 17.8% and 15.9%. The 2026 rates reflected withholding taxes on foreign earnings no longer permanently reinvested, incentives, share-based-compensation adjustments, and an unfavorable South Korean tax ruling. Corning recorded a $92 million noncash tax charge in Q1 after that ruling for 2010–2012 and intends to appeal a judgment received October 1 on remaining matters. The disputed-tax deposit receivable was $150 million at September 30, down from $248 million at year-end. The IRS is examining 2015–2018 and 2019–2020, including the transition tax; Corning believes its position is more likely than not to be sustained, but an adverse outcome could materially affect its financial statements. A separate Luxembourg ruling reduced deferred tax assets by $879 million, offset by a corresponding valuation-allowance reduction, with no income-tax provision impact.

Share-based compensation expense was $48 million in Q3 and $298 million in 9M, versus $99 million and $216 million. Foreign-currency translation produced Q3 OCI gains of $403 million versus losses of $89 million, and 9M gains of $227 million versus $437 million. Corning was a potentially responsible party at 21 hazardous-waste sites; its accrued, undiscounted cleanup and related-litigation liability remained $89 million, and management considered a material adverse outcome remote. Solar manufacturing expansion, inventory growth to $3.646 billion from $3.077 billion, and the customer agreement’s future delivery obligations are notable execution and operating commitments.

Corning (GLW) — Q3 and nine months ended September 30, 2026

Results

GAAP sales grew 18% in both periods; gross margin was 37% of sales in Q3, unchanged year over year, and 37% for 9M versus 36%. Higher Optical Communications profit was partly offset by temporary Solar capacity-ramp costs. Q3 SG&A declined 10% to $563M from $624M, mainly reflecting lower share-based compensation as performance-award fair values changed with Corning’s stock price; 9M SG&A rose 9% to $1.759B from $1.610B. R&D and engineering expense increased 12% to $314M from $280M in Q3 and 8% to $891M from $826M for 9M.

Core results are management-defined non-GAAP measures. Adjustments for hedged exposures increased core sales by $226M in Q3 and $459M for 9M, and core net income attributable to Corning by $175M and $334M, respectively. Effective April 1, 2026, Corning replaced its prior constant-currency method with an adjustment for hedged exposures; 2025 comparatives were not recast, limiting comparability.

Segment performance

Q3 segment revenue and segment net income (loss), reported basis:

Optical Communications was the principal growth and profit engine: Enterprise demand, particularly for generative-AI products, drove strong sales and incremental profit. Glass Innovations’ Q3 decline primarily reflected lower volume as rising memory prices affected end markets. Solar’s production ramp lifted sales but expansion costs reduced profit; Life Sciences and Emerging Growth Businesses incurred higher losses, reflecting emerging-business R&D and, for 9M, Pharmaceutical Technologies. Automotive sales benefited from demand for diesel products and adoption of auto-glass solutions, but higher Q3 operating costs offset the sales benefit. Effective Q1 2026, Corning reorganized reporting into the segments shown above.

Cash flow and financial position

Operating cash flow benefited from higher net income and a $1.0B upfront customer deposit under a long-term supply agreement. Higher capex accounted for $449M of the increased investing outflow, partly offset by $231M of higher realized gains on translated-earnings contracts. Financing outflow included $679M of incremental debt payments and $207M higher employee stock-award withholding-tax payments, partly offset by $500M of pre-funded warrant proceeds and $164M higher debt and short-term borrowing proceeds. Full-year 2026 capex is expected to be approximately $2.0B.
*Approximate prior-period amount implied by the reported $449M increase.

At September 30, 2026, cash and cash equivalents were $2.537B, approximately 66% held outside the U.S.; total debt was $8.200B versus $8.434B at December 31, 2025, and long-term debt was $7.267B versus $7.630B. Debt to total capital fell to 36% from 41%, below the revolver covenant maximum of 60%; Corning reported covenant compliance. The $1.5B committed revolver, expiring July 2030, and $1.5B commercial-paper program were undrawn. $0.9B of debt and short-term borrowings is due within one year, expected to be funded from cash, operations, committed capacity and, if appropriate, refinancing.

Working capital rose to $4.757B from $3.308B; the current ratio was 1.7:1 versus 1.6:1. Net trade receivables were $3.101B versus $2.779B, with DSO improving to 57 from 60; inventory increased to $3.646B from $3.077B. Non-recourse factoring and supply-chain programs accelerated collection of $442M of receivables by September 30, compared with $277M a year earlier.

Strategy, earnings drivers and risks

Corning extended its Springboard plan in May 2026, targeting a $20B annualized core-sales run rate by year-end; Q3 reached $20.3B, one quarter early, from a $13B run rate when the plan began in Q3 2023. Management intends to pursue profitable growth, stronger returns on invested capital and free cash flow, investing where customer demand supports attractive returns.

Net translated earnings contract gains were $138M pretax and $106M net in Q3, versus $33M and $25M; 9M gains were $212M pretax and $162M net, versus $63M and $48M. These realized and unrealized hedge effects materially contributed to pretax growth. Q3 tax provision was $222M versus $80M (22.9% effective rate versus 14.5%); 9M provision was $383M versus $219M (17.8% versus 15.9%). Rate drivers included foreign withholding taxes, incentives, share-based compensation, reserves and an unfavorable South Korean tax ruling. IRS examinations cover 2015–2020 federal returns, including transition-tax matters; an adverse outcome could materially affect results.

Key sensitivities include global demand, major-customer orders and creditworthiness, pricing and competition, supply-chain and critical-material availability, cost and timing of capacity investment, currency and commodity volatility, interest rates, tariffs and geopolitical events, and Solar ramp-up and profitability. Other risks include technology change, product performance, cyber and IP disruption, litigation, regulation and tax-law changes. Corning reported no material change to critical accounting estimates since its 2025 Form 10-K.

Corning reported no material change in its exposure to market risk since its 2025 Form 10-K. Its international operations expose earnings to foreign-exchange movements affecting foreign-currency-denominated financial instruments and transactions. Currency movements also affect reported results when Corning translates foreign subsidiaries’ non-U.S.-dollar net assets and net income into U.S. dollars. For details of its exposures and mitigation practices, Corning refers investors to its 2025 Form 10-K.

As of September 30, 2026, Corning concluded that its disclosure controls and procedures were effective. Management reported no changes during the period that materially affected, or were reasonably likely to materially affect, internal control over financial reporting. This section reports no financial results, business risks, or strategic developments.

Risk Factors

Corning’s report does not detail specific risk factors in this section. It directs readers to the risk factors in its 2025 Form 10-K and to the “Forward-Looking Statements” section of this report. The company cautions that the disclosed risks are not exhaustive: unknown risks, or factors currently considered immaterial—including economic, business, competitive, regulatory, or other factors—could materially adversely affect its business, financial condition, or operating results. This section provides no financial metrics or specific new risks or changes from prior periods.

During Q3 2026, the three months ended September 30, no Section 16 reporting persons adopted, modified, or terminated a Rule 10b5-1 trading plan or a non-Rule 10b5-1 trading arrangement.
