Corning's Stock Falls Despite Strong Optical Growth, Raising Questions for Coherent Investors
On July 28, Corning (GLW) reported a significant drop in its stock price of over 20%, despite achieving strong optical growth. The company’s second-quarter core sales rose by 17% year-over-year to $4.74 billion and earnings increased by 30%. Optical Communications revenue surged 32% to $2.07 billion, with Enterprise Networks growing at a faster rate of 65%, driven largely by generative AI product demand. However, the stock decline followed Corning’s third-quarter guidance falling short of Wall Street expectations. The company projected core sales between $4.9 billion and $5.0 billion for Q3—slightly below forecasts—and optical growth slowed from a 36% increase in Q1 to 32%. Coherent (COHR), which supplies active components used alongside Corning’s fiber infrastructure, also saw its stock fall sharply. Despite the drop, recent data suggests that demand remains strong for both companies. Coherent reported a revenue rise of 21% and expanded capacity due to robust AI network demands. While Corning's guidance may signal slower growth in optical deployments, it does not necessarily reflect weaker performance from Coherent.
