What this company does
Corning makes specialty glass, ceramics, and optical fiber for industries including telecom networks, smartphone displays, automotive emissions, life sciences labware, and solar-grade silicon through its Hemlock subsidiary. The company earns money primarily by selling these engineered materials and components to manufacturers and carriers, with Optical Communications and Display Technologies as its largest revenue segments. Sales jumped 21% year-over-year to $4.1 billion in Q3 2025 as Corning rides surging demand for AI data center optical connectivity, swinging from a prior-year loss to $430 million in net income.

- Working capital drain: receivables +$429M and inventories +$266M YTD outpaced sales growth, signaling potential demand softness or channel buildup.
