In brief
- Corning Optical Communications sales rose 44% year over year to $2.38 billion in Q3 2026.
- Enterprise networks sales within the optical unit jumped 84%, tied to generative AI demand.
- Core sales rose 19% to $5.08 billion; core EPS of $0.91 topped consensus.
- Q4 core sales guidance stands at $5.2 billion to $5.3 billion, roughly 19% growth.
- Corning management targets $30 billion in annualized sales by end-2028 and $40 billion by end-2030.
Enterprise networks lead the quarter
The biggest number is inside the optical unit. Sales in its enterprise networks business jumped 84%, a gain Crypto Briefing tied to the push toward generative AI.
That's a big figure.
Crypto Briefing also reported that the enterprise growth has outpaced the growth of GPU shipments. The comparison comes from Crypto Briefing's report, and it's a useful data point for anyone tracking where AI infrastructure dollars actually land (chips are only one part of the bill).
At the company level, Corning's core earnings per share came in at $0.91, topping consensus estimates, according to the report.
Guidance and long-range targets
Corning guided fourth-quarter core sales to a range of $5.2 billion to $5.3 billion, which implies roughly 19% growth, Crypto Briefing said. Management's longer-range goals are bigger: $30 billion in annualized sales by the end of 2028 and $40 billion by the end of 2030.
Those are Corning's stated targets. They aren't results yet.
The company has also signed multibillion-dollar agreements with Verizon, AT&T and Nvidia, according to Crypto Briefing. The report didn't spell out deal terms, and we're not going to guess at them.
A volatile year for the stock
The share price tells a messier story. Corning's market capitalization sat at roughly $109 billion to $113 billion after the third-quarter report, per Crypto Briefing. Getting there hasn't been a straight line, though, because shares have been volatile throughout 2026 and at one point had fallen roughly 50% from their June highs.
Crypto Briefing attributed part of that pressure to wider unease about AI capital spending. It's the same worry that's hung over much of the AI hardware trade this year, and Corning's optical numbers now sit right in the middle of it.
