Corning (GLW.DE) Stock Analysis & Winston Score
Corning makes specialty glass and materials that go inside everyday products. Its most famous product is Gorilla Glass, the tough screen cover used on smartphones made by Apple, Samsung, and other phone brands. The company also makes fiber-optic cables used to carry internet data, glass for TV screens, and materials used in cars and laboratories. Corning earns money by selling these materials to large manufacturers around the world. It operates globally, with major customers in the United States, Asia, and Europe, and generates roughly $14 billion in annual revenue. Its main competitive advantage is deep technical expertise in specialty glass that is very hard for competitors to copy. The biggest growth driver right now is demand for fiber-optic cable, as telecom companies and data center operators spend heavily to expand high-speed internet networks — though a slowdown in smartphone sales or capital spending by telecom companies remains a key risk.
