01—Abstract
Summary
Summary of the 8-K filed April 28, 2026. Cited figures are marked; the original filing is the authoritative source.
Corning reported first-quarter 2026 results that beat its own growth trajectory.
Core sales rose 18% year over year to $4.35 billiona, and core EPS rose 30% to $0.70. GAAP sales were $4.14 billion (up 20%), and GAAP diluted EPS was $0.43, up from $0.18. Optical Communications sales grew 36% and the new Solar segment grew 80%, driven by demand for Gen AI products and the ramp of new solar products.
Management also said two additional hyperscale customers signed large, long-term agreements similar in size and duration to the recently announced multiyear, up-to-$6 billionb Meta agreement. For the second quarter, Corning guided to core sales of about $4.6 billion (up roughly 14%) and core EPS of $0.73 to $0.77 (up roughly 25%). The guidance includes about $30 million of additional expense from an extended maintenance shutdown at the solar wafer facility, which includes a transition to a permanent power system.
Investors should also note that Solar sales rose 80% while Solar segment net income fell 74% year over year, and that GAAP operating cash flow of $362 millionc and adjusted free cash flow of $188 million are modest relative to capital expenditures of $332 million. The 8-K also recasts segment results to a new four-segment structure (Optical Communications, Glass Innovations, Automotive, Solar), with Life Sciences and Emerging Growth Businesses grouped as other.
The recast is voluntary, does not change GAAP consolidated results, and gives investors restated 2024 and 2025 segment data ahead of the 2026 10-Q and 10-K filings. Corning will update its Springboard plan through 2030 and introduce a Photonics Market-Access Platform at its May 6, 2026 investor event at the NYSE.
02—Key points
Key Highlights
- Q1 2026 core sales of $4.35B (+18% y/y) and core EPS of $0.70 (+30% y/y); GAAP sales of $4.14B (+20%) and GAAP diluted EPS of $0.43 (vs. $0.18 in Q1 2025).
- Optical Communications sales rose 36% y/y to $1.85B, and Solar sales rose 80% y/y to $370M, with Solar segment net income down 74% y/y to $7M.
- Two additional hyperscale customers signed large, long-term agreements similar to the recent multiyear, up-to-$6 billion Meta agreement, supporting the AI data center thesis.
- Q2 2026 guidance: core sales of about $4.6B (+14% y/y) and core EPS of $0.73 to $0.77 (+25% y/y), including about $30M of extra expense from an extended solar wafer maintenance shutdown.
- Core operating margin of 20.2% (+220 bps y/y), core gross margin of 39.1% (+120 bps), and core ROIC of 13.5% (vs. 11.6%); management says the polysilicon business is above its 20% corporate operating margin target.
- Cash generation was modest: GAAP operating cash flow of $362M and adjusted free cash flow of $188M, against capital expenditures of $332M. Total debt rose to about $8.97B from about $8.43B at year-end 2025.
- Segment recast to four reportable segments (Optical Communications, Glass Innovations, Automotive, Solar) with 2024 and 2025 restated; the recast is voluntary and does not change GAAP consolidated results. Springboard plan extension and a new Photonics Market-Access Platform will be presented at the May 6, 2026 investor event.
03—Questions
Frequently Asked Questions
How strong was Corning's Q1 2026 performance relative to last year?
Core sales grew 18% to $4.35 billion and core EPS grew 30% to $0.70. GAAP sales rose 20% to $4.14 billion, and GAAP diluted EPS rose to $0.43 from $0.18. Growth was led by Optical Communications (+36%) and Solar (+80%), while Glass Innovations grew only 1% and Automotive was flat to down slightly.
What is driving the growth in Optical Communications and Solar?
Management attributes Q1 growth to robust demand for Gen AI products, including hyperscale data center demand, and to the ramp of new solar products. Two additional hyperscale customers signed large, long-term agreements similar to the recent multiyear, up-to-$6 billion Meta agreement.
What should investors expect for Q2 2026?
Management guided to core sales of about $4.6 billion (up about 14% y/y) and core EPS of $0.73 to $0.77 (up about 25% y/y). The outlook includes an additional $30 million of expense from an extended maintenance shutdown at the solar wafer facility, which includes a transition to a permanent power system and equipment upgrades intended to raise throughput in future quarters.
Why did Solar segment earnings fall even though sales rose sharply?
Solar sales rose 80% to $370 million, but segment net income fell 74% to $7 million from $27 million a year earlier. The 8-K does not explain the drivers in detail. Q4 2025 Solar net income was $30 million, so the segment's profitability is volatile. Management said its polysilicon business performed above the 20% corporate operating margin target, while the module business is expected to cross over in Q2 2026.
Why did Corning recast its segment results, and does it change reported financials?
The company revised its segments to match how its chief operating decision maker reviews performance: Display and Specialty Materials were combined into Glass Innovations, Hemlock and the solar businesses became Solar, and Life Sciences was folded into Life Sciences and Emerging Growth Businesses. The recast is voluntary, is not a restatement, and does not change GAAP consolidated net income, EPS, operating income, or total assets and liabilities for any previously reported period.
