The Corning story

What drives the business

• Corning builds on expertise in glass science, ceramics and optical physics across communications, displays, mobile devices, automotive products and life sciences, and is the largest worldwide producer of glass substrates for flat panel displays.
• Its multiyear, multibillion-dollar Amazon agreement covers optical fiber, cable and connectivity for American data centers, while its NVIDIA partnership calls for expanding American optical connectivity manufacturing capacity by 10x and fiber production capacity by more than 50%.
• Optical Communications represented 38% of total segment net sales in 2025, and its sales grew 32% to $2.07 billion in the quarter to June 2026 as generative AI products grew significantly faster than the segment overall.
• Glass Innovations combined Display and Specialty Materials in the first quarter of 2026, bringing together display substrates, Gorilla Glass and semiconductor optics, with customer relationships including Apple's use of Ceramic Shield.
• Solar includes Hemlock Semiconductor and solar wafer and module manufacturing, and its sales grew 90% in the quarter to June 2026 as Corning completed an extended maintenance shutdown and equipment upgrade at its wafer facility.

What the price assumes

At $168.97, the reverse DCF implies that free cash flow after stock pay grows 26.0% a year for ten years, using a 10.3% discount rate.

Corning delivered 12.8% annual growth on that measure over the last 5 years, while the TenQ check sets an 8.4% bar by slowing that record halfway to 4%.

Revenue growth accelerated to 19.4% over the last twelve months from a 3.3% annual pace over the last three years, but sustained cash growth at the implied rate remains above Corning's record.

What could change the story

• The optical expansion requires capital spending to stay aligned with customer demand, while return on capital employed of 9.6% falls short of the TenQ check's 10.0% bar.
• Solar recorded a segment net loss in the quarter to June 2026 despite rapid sales growth, leaving manufacturing execution and the availability of government incentives important to its profitability.
• Operating cash flow of $1.72 billion in the quarter to June 2026 included $880 million from customer deposits and government incentives, making the timing of those receipts important when assessing repeatable cash generation.
• Total debt of $8.4 billion exceeds cash and short-term investments of $2.5 billion, and the debt-to-equity ratio increased to 0.67 from 0.57 five years earlier.
• Shares increased 1.6% over 3 years, and the September 2026 Equity Distribution Agreement with Goldman Sachs creates a further potential source of dilution.

What to watch next

• For the third quarter of 2026, management expects core sales of $4.9 billion to $5 billion, growing approximately 16%, and core EPS of $0.85 to $0.89, growing approximately 28%.
• Solar's segment earnings will show whether the completed wafer facility upgrade supports management's expectation of an improving earnings contribution starting in the third quarter of 2026.
• Optical sales, margins and free cash flow will show progress toward the Springboard Plan's annualized sales run rate of $20 billion by the end of 2026 and $30 billion by the end of 2028.
• Core results also warrant comparison with GAAP results because Corning changed its currency adjustment methodology in April 2026 without recasting prior periods.
