Corning Earnings: Why Did Optical Sales Jump 44% in the Third Quarter?

Corning (NYSE:GLW) reported on Tuesday, October 27, core earnings per share of $0.91 for the third quarter, up 36% from $0.67 a year earlier. On a GAAP basis, diluted EPS was $0.78, up 56% from $0.50. The EPS estimate as screened was $0.88, so the core figure came in 3.41% above it as screened.

Core net sales were $5.081 billion, up 19% from $4.272 billion, and GAAP net sales were $4.855 billion, up 18% from $4.100 billion. The main driver was Optical Communications, where sales rose 44% year over year to $2.379 billion, up from $2.072 billion in the second quarter, and where Enterprise Networks sales rose 84%.

Management said sales of products used in generative AI data centers more than doubled, outpacing growth in GPU unit volumes. It credited faster customer adoption of Corning innovations.

Corning Segments and Springboard: Which Businesses Held Back the Quarter?

Glass Innovations sales fell 3% to $1.506 billion, and segment net income fell 10% to $328 million. Management said the unit outperformed television, notebook and smartphone markets that were weighed by memory pricing.

Solar sales rose 37% to $436 million, but the segment posted a loss of $7 million because production ramped more slowly than planned. Management said productivity gains should lift output and profit, and it expects a U.S. Section 232 trade action to support pricing for U.S.-made solar products.

The company said it signed four long-term, multibillion-dollar customer agreements in the quarter, including with Verizon (NYSE:VZ) and AT&T (NYSE:T). It said the acceleration of its Springboard Plan has begun, with a target of doubling the annualized sales run rate from $20 billion to $40 billion by the end of 2030, and that capacity additions are backed by agreements that share cost and risk.
