Summary
Summary of the 8-K filed July 28, 2026. Cited figures are marked; the original filing is the authoritative source.
Corning Incorporated (NYSE: GLW) reported second-quarter 2026 results that management characterizes as strong, with GAAP net sales of $4.51 billiona (up 17% year over year) and core sales of $4.74 billion (up 17%).
GAAP diluted EPS was $0.64b (up 19%), and core EPS was $0.78 (up 30%). Growth was led by Optical Communications, where sales rose 32% to $2.07 billion, including a 65% increase in Enterprise Networks, and Solar, where sales rose 90% to $438 million. Core gross margin expanded 120 basis points to 39.6%, core operating margin expanded 190 basis points to 20.9%, and core ROIC improved to 14.9%.
Adjusted free cash flow was $1.42 billionc. Notably, GAAP operating cash flow included a sizable increase in customer deposits and government incentives ($880 million in the quarter), which investors should consider when assessing the quality of cash generation. Management reaffirmed and upgraded its internal Springboard Plan, targeting annualized sales run rates of $20 billion by end-2026, $30 billion by end-2028, and $40 billion by end-2030, implying a 19% sales CAGR from Q4 2026 to Q4 2030.
The company cited a multiyear, multibillion-dollar supply agreement with Amazon for optical fiber, cable and connectivity solutions, and a long-term NVIDIA partnership under which Corning will expand U.S. optical connectivity manufacturing capacity 10x and U.S. fiber capacity by more than 50%. For Q3 2026, management guided to core sales of $4.9 to $5.0 billiond (about 16% growth) and core EPS of $0.85 to $0.89 (about 28% growth), and expects Solar profitability to improve as its ramp continues toward more than $3 billion in revenue. Key considerations include the Springboard targets, which are internal aspirations rather than formal guidance; the heavy reliance on AI-driven optical demand; the Solar segment, which posted a GAAP net loss of $7 million in Q2 and depends on successful ramp execution; and the rising leverage and non-GAAP adjustments, including a new 'adjustment for hedged exposures' that replaced the prior constant-currency methodology and makes year-over-year growth comparisons less like-for-like.
The filing also shows GAAP net income attributable to Corning rose to $559 million, and total debt increased to $8.4 billion. This 8-K furnishes the earnings release under Item 2.02 and is not deemed filed for Section 18 purposes.

03—Questions
Frequently Asked Questions
How strong were Corning's Q2 2026 results compared with the prior year?
GAAP net sales rose 17% to $4.51 billion and GAAP diluted EPS rose 19% to $0.64. On a core (non-GAAP) basis, sales rose 17% to $4.74 billion and EPS rose 30% to $0.78. Core gross and operating margins expanded by 120 and 190 basis points, respectively.
What is the Springboard Plan, and how should investors interpret its targets?
The Springboard Plan is management's internal growth framework, targeting annualized sales run rates of $20B by end-2026, $30B by end-2028 and $40B by end-2030, and a 19% sales CAGR from Q4 2026 to Q4 2030 with faster earnings growth. These are internal aspirations rather than formal guidance, so their achievement depends on continued execution and demand, particularly in optical communications and solar.
What is driving growth, and how concentrated is it?
Optical Communications is the primary driver, with sales up 32%, including a 65% increase in Enterprise Networks, supported by AI data center demand. The Amazon supply agreement and the NVIDIA partnership (expanding U.S. optical connectivity capacity 10x and U.S. fiber capacity by over 50%) reinforce this. Solar sales grew 90%, but the segment posted a small GAAP loss in Q2. Concentration in AI-related demand is a key risk to monitor.
Why do GAAP and core EPS differ so much, and what changed in the non-GAAP methodology?
The gap reflects adjustments for hedged exposures, largely non-cash discrete tax items, and restructuring and impairment charges. Effective April 1, 2026, Corning replaced its constant-currency adjustment with an 'adjustment for hedged exposures,' which applies contractual hedge rates only to the hedged portion of exposure. The company notes that applying the new method to 2025 comparatives would have produced higher year-over-year core growth rates, so prior-period comparisons are not directly comparable.
What does the Q3 2026 outlook imply for investors?
Management guided Q3 core sales to $4.9–$5.0 billion (about 16% growth) and core EPS to $0.85–$0.89 (about 28% growth). It expects Solar profitability to improve as its ramp continues toward more than $3 billion in annual revenue. Guidance is provided only on a core basis because management cannot forecast certain items required for a GAAP reconciliation.
