Correction — October 27, 2026: The headline now describes a new fourth-quarter forecast. The release did not establish an increase to an existing fourth-quarter forecast.
Corning reported third-quarter core sales of $5.08 billion on October 27, up 19% from a year earlier, as optical-communications demand expanded.
Core earnings reached 91 cents per share. Core results are supplemental financial measures and differ from results calculated under generally accepted accounting principles.
Optical Communications sales increased 44% to $2.38 billion. Within that business, Enterprise Networks sales grew 84%, while sales of products for generative artificial intelligence more than doubled, according to the company.
Corning also reported 37% sales growth in its solar business. It said production continued increasing, though more slowly than anticipated.
The company secured four long-term, multibillion-dollar customer agreements during the quarter, including agreements with Verizon and AT&T.
For the fourth quarter, management expects core sales between $5.2 billion and $5.3 billion and core earnings of 96 cents to $1 per share. These ranges describe projected performance; they are not completed sales or earnings.
