Corning Incorporated (NYSE: GLW) saw its stock price surge significantly in late March 2026, driven by a combination of bullish analyst sentiment and strategic announcements related to artificial intelligence (AI) infrastructure. On March 23, the stock jumped over 5%, closing between $131 and $133 after opening near $124.58. The rally continued, with shares reportedly climbing more than 9% in a subsequent session to reach approximately $143.38.
The immediate catalyst was a price target increase from Bank of America Securities. Analyst Wamsi Mohan raised the target to $155 from $144, maintaining a Buy rating. Mohan cited "increased confidence in the optical cycle playing out and even higher per GPU content in scale out," highlighting Corning's role in supplying the fiber optic connectivity essential for expanding AI data centers. This upgrade followed a prior target hike by BofA and similar bullish moves from other firms like Citigroup, which has a $170 target.
Concurrently, Corning made key technology announcements at the OFC 2026 conference. The company showcased advanced products for high-density AI networks, including multicore fiber and co-packaged optics. More significantly, Corning licensed its PRIZM TMT optical ferrule technology to US Conec. This technology enables more fiber connections in compact spaces, directly addressing the bandwidth and physical footprint challenges in AI data center scaling.
The company's financial performance underpins the optimism. Its most recent quarterly results showed sales up 20% to $4.22 billion and earnings per share (EPS) soaring 72% to $0.62. Optical communications, which contributed roughly 40% of net income, is expected to grow 15–20% annually, fueled by industry-wide AI capital expenditure. Corning has guided for next-quarter EPS between $0.66 and $0.70.
Despite the rally, the stock at $131.85 remained about 17.8% below its 52-week high of $160.43. The company plans $1.7 billion in capital expenditure for 2026 to expand capacity for AI-related and solar manufacturing. Potential headwinds include a high P/E ratio around 70, competitive pressure from technologies like NVIDIA's copper interconnects, and broader market volatility influenced by geopolitical factors.
