Optical communications leads growth

Corning's third-quarter results and fourth-quarter outlook remain the main operating reference for investors. In its October 27 earnings release, the company said core sales increased 19 percent year over year to 5.08 billion US dollars, while core earnings per share rose 36 percent to 0.91 US dollars. Core figures are non-GAAP measures; Corning reported GAAP sales of 4.86 billion US dollars and GAAP diluted earnings per share of 0.78 US dollars.

Optical Communications generated third-quarter sales of 2.379 billion US dollars, up 44 percent from a year earlier. Enterprise Networks sales increased 84 percent, and sales of generative artificial intelligence products grew more than 100 percent year over year, according to Corning.

Fourth-quarter execution matters

Management expects fourth-quarter core sales of 5.2 billion to 5.3 billion US dollars, representing year-over-year growth of approximately 19 percent. Core earnings per share are expected in a range of 0.96 to 1.00 US dollars, with growth of approximately 36 percent.

The company also said it secured four long-term, multibillion-dollar customer agreements during the third quarter, including agreements with Verizon and AT&T. For investors, the next test is whether capacity additions and demand from AI data-center customers translate into sustained volume and profitability.
