Corning’s AI Infrastructure Pivot Drives Triple-Digit Gains Amid Valuation Concerns

Corning (GLW) has emerged as a dominant force in the artificial intelligence build-out, with its shares skyrocketing 311% over the last twelve months, vastly outperforming the S&P 500's 29% gain. While historically recognized for its Gorilla Glass displays, the company's current growth is primarily driven by the insatiable demand for high-speed optical fiber used to interconnect AI processors. The company's strategic shift toward AI infrastructure is highlighted by a massive partnership with Meta Platforms. The two firms have broken ground on a North Carolina facility intended to be the world's largest fiber optic cable factory, part of a supply agreement valued at up to $6 billion. Fiscal 2025 results underscore this momentum, with annual revenue climbing 19% to $15.6 billion. Core net income rose 29% to approximately $2.2 billion, resulting in earnings per share of $2.52. Despite the strong performance, analysts anticipate a deceleration in 2026. Consensus revenue forecasts sit at $18.8 billion, representing a growth rate of less than 15%, while core net income per share is expected to reach $3.12. With a forward P/E of 55 and a price-to-sales ratio of 9.5, the stock is priced for perfection, raising concerns about a potential cyclical peak.
