Oct 28, 2026
Corning’s shares fell 1.1% after earnings, a roughly flat reaction. Q3 growth and Q4 guidance were strong in absolute terms, but the transcript does not identify a specific disappointment behind the move.
Key takeaways
- Q3 sales rose 19% year over year to $5.1 billion, and core EPS increased 36% to 91¢; both were above guidance.
- Gross margin expanded 150 basis points to 40.5%, while operating margin rose 310 basis points to 22.7%.
- Free cash flow was $661 million after more than $500 million of capacity investment.
- For Q4, Corning guided to sales of $5.2 billion–$5.3 billion and EPS of 96¢–$1, representing about 19% and 36% year-over-year growth, respectively.
- Management said the Q3 sales run rate was $20.3 billion and forecast a $21 billion run rate at Q4’s guidance midpoint, above its $20 billion year-end 2026 SpringBoard target.
Q2 2026
Jul 30, 2026
Shares fell 13.5% following the earnings release, reflecting investor disappointment with the cautious outlook and potential deceleration implied in management’s longer-term guidance. Despite strong revenue and profit growth in the quarter, the market focused on tempered forward growth assumptions and less optimistic end-market conditions.
Key takeaways
- Q2 sales grew 17% year-over-year to $4.74 billion, supported by a 32% increase in Optical Communications sales to over $2 billion.
- EPS increased 30% to $0.78, and gross margin expanded 120 basis points to 39.6%, driven by operating margin improvement of 190 basis points to 20.9%.
- Free cash flow rose to $1.42 billion, reflecting solid cash conversion.
- Management reiterated a 19% sales CAGR target for 2027-2030 but incorporated assumptions of flat end markets in TV, IT, and smartphones, plus declining internal combustion engine demand partially offset by automotive content gains.
- Despite upgrades in solar wafer capacity and significant multi-billion dollar customer agreements, guidance appears cautious, with risk-adjusted plans factoring in weaker growth potential, which likely weighed on investor sentiment.
Q1 2026
Apr 29, 2026
Corning shares fell 9.6% after Q1 results, as investors reacted negatively to the company’s updated outlook, citing higher-than-expected expenses for the coming quarter and a slower-than-anticipated ramp in the key solar wafer facility, which will undergo an extended maintenance shutdown.
Key takeaways
- Q1 sales rose 18% year-over-year to $4.35 billion, with EPS up 30% to $0.70 and operating margin expanding to 20.2%.
- Solar segment sales grew 80% year-over-year; however, production issues delayed the ramp of the new U.S. wafer facility, which now faces an extended shutdown for upgrades.
- Management built $30 million of additional expense into Q2 guidance related to solar facility downtime, weighing on near-term profitability.
- Optical Communications segment drove strong growth, including large new long-term supply agreements with hyperscale customers.
- Despite positive sales trends and upgraded long-term targets, operational execution and higher costs overshadowed reported Q1 strength in the market’s view.
