Corning forecasts first-quarter sales above estimates on strong optical fibre demand

Corning on Wednesday forecast first-quarter ‍sales above estimates, ​boosted by resilient demand for its ⁠fibre‑optic products, which generate nearly 40% of the company's revenue.

The Gorilla Glass maker, a key supplier ‌to Apple, ‌has stepped up investment in its optical communications business ‌as major technology companies race to expand data‑centre infrastructure to support rising AI workloads.

On Tuesday, Corning inked an up to $6 billion multi‑year deal with Meta Platforms to supply fibre-optic cables for the social ‌media giant's ‍AI‑focused data centres.


Corning's optical connectivity ‍hardware is central to handling the heavy ‌computing and data‑transmission requirements of modern AI infrastructure.

The company's shares have risen about 26% this year, extending their 84% gain in 2025.

For the first quarter of 2026, Corning expects core sales ‍in the range of $4.2 billion to $4.3 billion, the mid-point of which ‍is above ⁠analysts' estimates ⁠of $4.23 billion, according to data compiled by LSEG.

The company's optical communications division recorded net sales of $1.70 billion for the fourth quarter, in line with estimates.

Core sales for the quarter beat expectations at $4.41 billion, compared with estimates of $4.35 billion.
