Corning Stock's AI Surge: After The Meta Blockbuster, Is GLW Still A Buy?

Core Viewpoint - Corning's stock surged 16% to $110 following a significant $6 billion multi-year agreement with Meta Platforms to supply fiber-optic cables for AI data centers, marking a new 52-week high for the company [2][3]. Financial Performance - For Q4 2025, Corning is projected to achieve revenue of $4.36 billion and EPS of $0.71, reflecting a 12.5% increase in revenue and a 24.6% growth in EPS year-over-year [6]. - The optical communications segment has shown remarkable growth, with a 33% increase in revenue to $1.65 billion in Q3 2025, and a year-over-year sales growth of 58% [4][6]. - For the full year 2025, analysts predict an EPS of $2.52 on approximately $16.35 billion in revenue, with 2026 estimates adjusted upward to $3.09 per share, indicating a 23% year-over-year EPS growth [7]. Valuation - Corning's stock trades at a trailing P/E ratio of around 71x based on TTM EPS of $1.56, which drops to 46x when using adjusted EPS of $2.38 [8]. - The forward P/E ratio is approximately 36x based on 2026 estimates, which is significantly higher than the historical median P/E of 18x over the past 13 years [9][8]. - The current valuation reflects a premium compared to the broader technology sector average P/E of 32x and peers like Thermo Fisher Scientific and TE Connectivity [9]. Growth Potential - The agreement with Meta provides revenue visibility through 2030, and the shift towards fiber in AI infrastructure presents a multi-year growth opportunity [10]. - Corning's management is confident in expanding production capacity to meet increasing demand, with plans for its North Carolina facility to become the largest fiber-optic cable manufacturing plant globally [7]. Market Sentiment - Despite the positive outlook, the $6 billion deal contributes only about 8-10% to Corning's annual revenue, which raises questions about its transformative impact [11]. - The stock has already doubled in the past 12 months, increasing 114% year-over-year, suggesting that much of the growth narrative may already be priced in [12]. - Analysts from Bank of America have set price targets at $110, indicating limited upside potential from current levels [13]. Risk-Reward Assessment - The current valuation requires Corning to sustain 25-30% annual EPS growth for several years to justify its price, which is considered ambitious [14]. - The stock's performance is significantly above historical norms, and any execution missteps or slower-than-expected AI deployment could lead to a contraction in multiples [15].
