Corning reported an 18% increase in third-quarter net sales to US$4.855 billion on 27 October, alongside 44% growth in Optical Communications sales. Reported net income attributable to Corning rose 58% to US$680 million.
Reported and core results are different
For the quarter ended 30 September 2026, diluted earnings per share were US$0.78 under US generally accepted accounting principles (GAAP), compared with US$0.50 a year earlier.
Corning separately reported core sales of US$5.081 billion and core EPS of US$0.91, versus US$0.67. Core is the company’s non-GAAP measure: it makes specified adjustments and does not replace the reported accounts.
A material comparison caveat applies. From 1 April 2026, Corning prospectively replaced its constant-currency adjustment with an adjustment for hedged foreign-currency exposures. Prior-period core amounts were not recast using the new method. This is separate from its changed segment presentation, for which prior periods were recast.
Optical sales and the next-quarter outlook
Optical Communications sales reached US$2.379 billion, up from US$1.652 billion. These are segment sales, not the group’s total revenue or net profit.
For the fourth quarter, management forecasts core sales of US$5.2 billion–US$5.3 billion and core EPS of US$0.96–US$1.00. These are expectations, not completed results. The release says it cannot provide a GAAP outlook reconciliation because it does not forecast certain currency movements and other adjustments.
