Key Highlights

  • Corning is expanding manufacturing capacity in North Carolina to address fiber shortages impacting U.S. data center and broadband projects.
  • The company has secured a multi-year, up-to-$6 billion agreement with Meta to support AI and data center infrastructure growth.
  • Corning’s optical communications sales increased by 24% in Q4, driven by enterprise and hyperscale data center demand.
  • Long-term agreements with major clients demonstrate Corning’s commitment to supporting next-generation connectivity solutions.
  • Despite supply chain challenges, Corning emphasizes innovation in high-density fiber and connectivity products to improve performance and reduce costs.

Speaking to investors during its fourth-quarter 2025 earnings call, Wendell Weeks, CEO and Chairman of Corning, noted that “there is enough fiber in the world to meet demand.”

Weeks emphasized that the company is seeing demand not only for fiber but also for cabling and connectivity products, such as its GlassWorks AI™ solutions for data centers and co-packaged optics (CPO), which are gaining momentum.

“Our capacity expansions are about our new high-density products in fiber, in cable, and in connectivity,” he said. “And for those, we are experiencing a very, very robust demand. That is why we continue to expand our capacity and improve our productivity for these products.”

He added that “over time, you'll see the mix impact of these more valuable innovations,” which will “enable our customers to have better and more reliable optical performance in about half the space with significantly reduced installation cost.”

Ramping long-term agreements

Regardless of any pending fiber shortage, Corning continues to ink agreements with key customers, including Meta.

On the eve of its fourth-quarter earnings announcement, Corning announced a multi-year up-to-$6 billion agreement to support Meta's apps, technologies, and AI plans using its fiber, cable, and connectivity solutions.

As part of the agreement, Meta will serve as the anchor customer for the expansion and upgrade of our manufacturing and technology capabilities across our North Carolina operations.

“This long-term partnership with Meta reflects our commitment to develop, innovate and manufacture the critical technologies to power next-generation data centers here in the U.S,” Weeks said.

While he did not call out specific customer names, Weeks noted that it is “concluding similar long-term agreements with other major customers to dedicate capacity for them as well.”

Enterprise, Gen AI drive optical growth

The ongoing adoption of our new Gen AI products led to Corning’s fourth-quarter Optical Communications results.

The fiber manufacturer’s Optical Communications fourth quarter sales were $1.7 billion, up 24% year-over-year. Net income was $305 million, up 57% year-over-year, and the net income margin was 18%.

For the full year of 2025, sales were $6.3 billion, up 35% year-over-year. Net income was $1 billion, up 71% year-over-year.

Edward Schlensinger, CFO of Corning, said an uptick in enterprise business sales drove the growth of 2025 full-year Optical Communications earnings.

“For the full year, our enterprise business, where we capture sales inside the data center, grew 61% year-over-year,” he said. “And the hyperscale data center portion of our business grew significantly faster.”

Likewise, Corning’s carrier networks business grew 15% year-over-year.  Schlesinger said sales primarily drove this “growth to interconnect data centers.”

Schlesinger added that we expect the [data center] segment to continue to drive significant growth,” and that “our recent Meta announcement is a great proof point.”

Looking ahead, Corning expects year-over-year sales growth to accelerate, with sales approximately 15% higher, in the range of $4.2 billion to $4.3 billion for data center interconnection and fiber-to-the-home (FTTH).
