Corning: A Fiber of Doubt and Potential

by

Herr Huang, of Nvidia—a name now synonymous with the feverish pursuit of artificial intelligence—declares that data centers may soon consume four trillion dollars annually in upgrades. A sum that chills the soul, does it not? To imagine such profligacy… yet, it is a testament to our age—an age obsessed with the intangible, the digital, the ethereal. Nvidia, naturally, will feast. But to assume it is alone in this banquet… that would be a dangerous simplification. There are others, hidden in the shadows, quietly weaving the very fabric of this new reality.

Corning, a name perhaps more readily associated with the fragile glass protecting our pocket idols—the iPhones—is one such entity. A seemingly humble supplier, yet essential. But to fixate solely on the glass is to miss the deeper currents. It is the fiber optic cables—the veins and arteries of the digital world—that truly reveal its significance. These strands, thinner than a human hair, are becoming the indispensable conduits for the relentless flow of information, surpassing the limitations of antiquated copper.

In the year now passing, 2025, Corning’s stock has ascended, a startling 84% rise, leaving even Nvidia’s respectable 39% gain in its wake. A curious disparity. Is it mere chance? A fleeting anomaly? Or does it betray a fundamental miscalculation in the market’s assessment of value? On January 28th, the company will unveil its final quarterly report, a reckoning of sorts. A moment of truth. And with it, the first glimpse into the coming year—a year that may well determine whether this ascent was a genuine awakening or a cruel illusion.

The Unfolding Drama of Fiber and Copper

The pursuit of artificial intelligence demands an insatiable hunger for computational power, a craving satisfied within the cavernous confines of data centers. Thousands of chips, humming with energy, locked in a perpetual dance of calculation. Graphics processing units—the favored instruments of this digital orchestra—rely on a supporting cast of processors, memory, and storage. But even the most powerful instruments are useless without a means of communication.

Data, like a restless spirit, must flow between these components with the utmost speed and efficiency. Copper, once the standard, now falters, its limitations painfully apparent. Fiber optic cables, however, offer a solution—a pathway for information to travel at near-light speed, over vast distances, with minimal loss. It is a matter of physics, yes, but also a matter of foresight.

Currently, a typical Nvidia NV-Link node—a nexus of processing power—requires approximately two miles of copper cabling to connect its 72 GPUs. A labyrinthine network, prone to bottlenecks and inefficiencies. Corning predicts—and I suspect correctly—that this antiquated system is rapidly giving way to fiber. And as each new generation of AI software demands ever greater computational capacity, the nodes will inevitably grow larger, requiring even more cabling. The implications are staggering.

Wendell Weeks, Corning’s CEO, speaks of a potential doubling, even tripling, of the data center fiber market. An optimistic projection, perhaps. But I see within it a kernel of truth. A recognition that the future belongs to those who control the flow of information. And Corning, it seems, is positioning itself to be a key player in this unfolding drama.

A Year of Reckoning and Promise

Through the first three quarters of 2025, Corning generated $12 billion in core revenue—a 13% increase from the previous year. But it is the optical communications segment that truly captures the imagination—$4.57 billion in revenue, growing at an astonishing 39%. And within that segment, enterprise optical communications—the heart of the AI-driven demand—soared by a staggering 58%. These are not mere numbers; they are symptoms of a fundamental shift in the technological landscape.

On January 28th, Corning will unveil its fourth-quarter results, and management anticipates $4.35 billion in core revenue. This would bring the total for 2025 to $16.3 billion—a 13% increase from the prior year. A notable acceleration, indeed. In 2024, Corning achieved only 7% growth. This is not simply progress; it is a metamorphosis.

But the true test lies in the guidance for 2026. Wall Street consensus predicts 13% growth, bringing total revenue to $18.4 billion. A reasonable projection, perhaps. But I suspect Corning may exceed these expectations, fueled by the insatiable demand for data center fiber. The market, however, remains skeptical. It prefers the familiar narrative, the established giants. But sometimes, the most profound transformations occur in the shadows, unnoticed by the masses.

A Question of Value and Perception

Over the past four quarters, Corning has generated adjusted earnings of $2.38 per share, resulting in a price-to-earnings ratio of 39.5. Nvidia, by comparison, trades at a lofty 45.9. And Broadcom, another major semiconductor equipment supplier, commands an even more exorbitant 51.5. A discrepancy, to be sure. Is Corning undervalued? Or is the market simply recognizing the inherent risks associated with a company that relies on a single, albeit promising, segment?

Looking ahead to 2026, Wall Street anticipates earnings of $3.09 per share, placing Corning’s forward price-to-earnings ratio at a mere 30.5. This means the stock would have to climb by 29.5% just to maintain its current P/E ratio. A daunting task, perhaps. But if Corning delivers on its promises, the potential upside is considerable.

The surging demand for fiber optic cables is granting Corning an enviable degree of pricing power. Its optical communications business is highly profitable, accounting for half of the company’s total net income. If this momentum continues, Corning’s earnings could surpass expectations, rewarding investors with an even greater return. The question is not whether Corning is a good company, but whether the market is capable of recognizing its true potential. A question that, like so many in the realm of finance, remains shrouded in doubt.
