Fiber business powers sharp sales uptick at Corning

Corning, one of the world’s major players in glassmaking and a pioneer in optical fiber production, has posted a sharp increase in sales revenues - thanks largely to a major uptick in demand for both optical communications and solar panel applications.

At just under $5.1 billion for the three months ending September 30, total sales were up 19 per cent on the same period last year. That means the firm is well on track to hit its end-of-year run-rate sales target of $20 billion, and making early progress with its latest “Springboard” growth plan to increase that annualized sales run-rate to $30 billion by the end of 2028, and $40 billion by the end of 2030.

Long-time CEO Wendell Weeks told an investor conference call discussing the latest quarter: “Our strong results provide excellent proof points of the acceleration of growth outlined in our ‘20-30-40’ Springboard Plan.”

Central to that acceleration is the huge uptick in demand for high-speed optical fiber links in AI data center architectures, with the CEO adding: “We continue to successfully expand our content within customers’ ecosystems and outperform our underlying markets. For example, in optical communications, faster adoption of our innovations helped us double our Gen AI sales year-over-year in the quarter, outpacing GPU unit growth.”

Overall, Corning’s optical communications unit reported a 44 per cent year-on-year increase in sales to $2.38 billion, with the AI-related growth underpinned by major deals signed with the likes of Amazon and Meta in recent months.

Weeks also highlighted a key point contained in generative AI pioneer Anthropic’s “S-1” filing this week. In the document, which lays out the thinking behind what is expected to result in a $100 billion initial public offering (IPO) of stock, the firm behind the “Claude” large-language models says its number-one constraint right now is compute power.

“And we provide the networking for that compute [power],” said Weeks. “What we see in our demand is a continued press from our customers to do more and more.”

Also growing quickly right now are the firm’s solar-related sales, which were up 37 per cent year-on-year to $436 million while the glass, automotive, and life sciences business units were close to flat.

On the bottom line, Corning was able to post a net income figure of $795 million overall, with the communications division contributing $532 million to that total - up 80 per cent on the same period last year.

Commenting on the way that the company shares share its technology and development plans with key customers to help meet challenging production ramps, Weeks noted:

“One example of a tool that we have used successfully in our glass and solar businesses - and have now applied in optical communications - is to have our customers provide up-front cash to fund our capacity.

“We then simply return the cash to our customers as they purchase committed volumes. This helps to both de-risk our capacity investments, and give our customers supply-chain assurance.”

Looking ahead, Weeks and his colleagues are expecting the current momentum to continue, with sales of around $5.25 billion in the closing quarter of the year likely bringing the 2026 total close to $19.5 billion.
