Corning (GLW) stock fell about 1% after its earnings, despite a 250% increase in the past year. The company's first-quarter results showed that it is benefiting from a wave of AI data center buildouts, with Optical Communications revenue rising 36% year over year to $1.846 billion, while segment net income jumped 93% to $387 million. Corning also signed two new long-term hyperscaler agreements, providing the company with greater visibility and reducing risk of single build cycles. However, Solar, which is rapidly growing, has shown challenges due to rising costs and minimal earnings contribution. The next proof is whether margins continue to rise even as spending increases.
