CORNING INC /NY (GLW)

Corning Incorporated is a materials science company that traces its origins to a glass business established in 1851 and was incorporated in New York in December 1936 (renamed from Corning Glass Works in 1989). It applies expertise in glass science, ceramic science and optical physics, together with manufacturing and engineering capabilities, to develop products for industries including optical communications, display, mobile consumer electronics, automotive, life sciences, semiconductors and solar. It manufactures in 14 countries and invests heavily in research, development and engineering.

The company reports five segments. Optical Communications (38% of 2025 segment net sales) sells optical fiber, cable, hardware and connectivity solutions for carrier networks (fiber to the home, 5G) and enterprise networks (including hyperscale data centers supporting AI), with brands such as SMF-28e, ClearCurve, Evolv and Edge8. Display (23%) makes glass substrates for LCD and OLED panels using its proprietary fusion process, with products such as EAGLE XG, Astra and Lotus NXT. Specialty Materials (13%) offers more than 150 glass, glass-ceramic and crystal formulations, including Gorilla Glass for mobile devices, semiconductor optics such as HPFS Fused Silica and ULE glass, wafers and substrates, and aerospace and defense optics. Automotive (11%), formed in 2025 by combining Environmental Technologies and Automotive Glass Solutions, makes ceramic substrates and particulate filters for emissions control plus technical glass for vehicle interiors and exteriors. Life Sciences (6%) supplies lab consumables, labware, glassware and equipment under the Corning, Falcon, PYREX and Axygen brands. Other businesses (9%) are grouped as Hemlock and Emerging Growth Businesses, mainly Hemlock Semiconductor Group (high-purity polysilicon for solar and electronics), solar wafer and module operations, and pharmaceutical glass tubing and vials.

Customers include telecommunications carriers, enterprises, governments and hyperscale data center operators; flat panel makers; mobile device makers (the company cites a collaboration with Apple); semiconductor equipment and chip manufacturers; emission control system manufacturers who supply automotive and diesel vehicle and engine makers; and pharmaceutical, biotechnology, academic, hospital and government laboratories. Life sciences products are sold mainly through distributors. Markets are global, with display glass operations and customer service concentrated in Asia.

Manufacturing sites are in the U.S. (including North Carolina, Texas, New York, Virginia and several other states), China, South Korea, Taiwan, India, Poland, Germany, France, Mexico and Brazil. Production requires uninterrupted power, industrial water, precious metals and batch materials such as ores, minerals, polymers, lithium, helium and chemicals; some key materials and equipment are sole-sourced or limited-source, and some are subject to export restrictions. Competitors vary by segment and include Amphenol, Fujikura, Sumitomo and Prysmian in optical; AGC and Nippon Electric Glass in display; Schott, Heraeus and JENOPTIK in specialty materials; NGK Insulators, Ibiden and LENS in automotive; and Thermo Fisher, Avantor, Greiner, Eppendorf, Sarstedt and Danaher in life sciences. Corning owned about 11,375 unexpired patents at the end of 2025, and patents and trademarks are important to its competitive position.
