Corning Slips 0.5% Despite Strong Q3 Growth and Upbeat Q4 Outlook
Corning (NYSE: GLW) shares fell about 0.5% even after the company reported third-quarter results above guidance, driven by strong demand in Optical Communications and continued AI infrastructure growth.
Core sales increased 19% year over year to $5.08 billion, while core EPS rose 36% to $0.91. GAAP sales increased 18% to $4.86 billion, and GAAP EPS climbed 56% to $0.78.
Optical Communications was the main growth engine, with sales up 44% to $2.38 billion. Enterprise Networks revenue increased 84%, while Gen AI-related product sales more than doubled. Solar sales also rose 37%, although production ramped more slowly than expected and the segment posted a $7 million loss.
Margins improved meaningfully. Core gross margin expanded 150 basis points to 40.5%, while core operating margin increased 310 basis points to 22.7%. Adjusted free cash flow was $661 million for the quarter.
For the fourth quarter, Corning expects core sales of $5.2 billion to $5.3 billion, representing about 19% growth, and core EPS of $0.96 to $1.00, up roughly 36% year over year.
The slight 0.5% decline appears to reflect a muted reaction to otherwise strong results, with investors possibly weighing slower-than-expected solar execution and weakness in Glass Innovations against robust AI-related optical demand, expanding margins and a strong Q4 outlook.
