Corning's stock fell 2.5% after beating Q3 expectations, but the real story is explosive growth in AI data centers and a huge Apple deal. We're hiking our target to $95—here's why this dip screams buy...

Financial market analysis from 28/10/2025. Market conditions may have changed since publication.

Have you ever watched a stock you love take a sudden nosedive right after posting numbers that should make investors cheer? That’s exactly what happened with a certain high-tech glass manufacturer this week, and honestly, it felt like the market was missing the forest for the trees.

Shares dropped over two percent on a day when everything else pointed upward. But sometimes, these moments of collective short-sightedness create the best entry points. In my view, this wasn’t a red flag—it was a green light disguised as temporary weakness.

Why the Post-Earnings Dip Was a Gift

Let’s start with the basics. The company in question delivered core sales growth of 14% year-over-year, hitting $4.27 billion. That beat what analysts were expecting by a comfortable margin. Earnings per share? Up 24% to 67 cents, just nudging past estimates.

Yet the stock fell. Profit-taking, sure. But dig deeper, and you’ll find a business firing on all cylinders, particularly in areas that matter most for the future: artificial intelligence infrastructure and premium consumer devices.

I’ve followed turnaround stories for years, and this one stands out. Two years into a strategic overhaul, sales are up 31%. Operating margins have expanded by 330 basis points. Return on invested capital? A whopping 460 basis point improvement. These aren’t vanity metrics—they translate directly to shareholder value.

The Springboard Initiative Delivering Ahead of Schedule

Management launched what they call their Springboard plan with ambitious targets. The original goal: add $3 to $4 billion in annualized sales by 2026. They blew past that, hitting $4 billion already through the third quarter.

Now they’re raising the bar to $6 billion by the end of next year. And get this—they expect to reach a 20% operating margin in the current quarter, a full year earlier than planned. In a world where companies often push targets out, this kind of execution deserves attention.

We’ve added $4 billion of incremental annualized sales through Springboard, and we see much more growth ahead with additional springs to come.

That quote captures the confidence flowing from the top. But confidence alone doesn’t move stocks—what does is the substance behind it.

Data Centers: The Real Growth Engine

Everyone talks about AI, but few discuss the physical infrastructure making it possible. This company sits at the heart of that buildout through its optical communications segment, particularly products enabling massive data center expansion.

Third quarter sales in this division jumped 33% year-over-year. The enterprise side—think hyperscale data centers—grew even faster at 58%. Management reiterated a 30% compound annual growth rate expectation through 2027, but current momentum suggests they might exceed that.

Think about what drives this. Two forces: scale-out and scale-up.

  • Scale-out: Hyperscalers adding more GPU clusters means more connected AI nodes. Each connection requires fiber optic cable—the company’s specialty.
  • Scale-up: Advanced AI nodes pack more GPUs with initially copper connections that eventually migrate to fiber for better performance. One next-generation node might replace miles of copper with fiber.

The CEO put it bluntly: success in scale-up could make this opportunity two to three times larger than the current enterprise business. That’s not incremental growth—that’s transformative.

They’re already working with major cloud providers to upgrade infrastructure. New high-density fiber systems allow two to four times more capacity in existing conduits. One major partner is using these solutions to enhance cloud and AI services reliability.

A Landmark Deal Reshaping Mobile Glass

Beyond data centers, a $2.5 billion agreement stands out. For the first time, 100% of glass for certain flagship smartphones and smartwatches will be produced domestically at a Kentucky facility.

This isn’t just about patriotism—it’s smart business. It creates a larger, longer-term growth driver in mobile consumer electronics. The partnership expands capacity and secures supply chains in an increasingly uncertain world.

Visiting that Kentucky plant recently left quite an impression. The precision, the scale, the integration with device assembly—it’s the kind of manufacturing excellence that builds competitive moats.

Segment Performance Breakdown

Let’s look across the portfolio to understand the full picture.

SegmentQ3 GrowthKey Insight
Optical Communications+33%Enterprise up 58%, AI-driven
Specialty Materials+13%Mobile glass momentum building
Hemlock & Emerging+46%Solar polysilicon sold out
Display Technologies-7.5% YoYSequential improvement, margins strong
Environmental+6%China light-duty vehicle recovery

The display segment decline grabs headlines, but context matters. Sequential sales rose 5%, and management expects full-year profit at the high end of guidance with at least 25% margins. This remains a cash cow funding growth elsewhere.

Solar represents perhaps the most underappreciated opportunity. The core material business—polysilicon—has capacity sold out for 2025 and over 80% committed through the next five years. From $200 million quarterly run rate earlier this year, management sees a $2.5 billion business by 2028.

Guidance That Signals Confidence

Fourth quarter outlook: $4.35 billion in sales, adding another $300 million to annualized run rate. That’s above consensus. Core EPS guidance of 68-72 cents also beats expectations.

Perhaps most telling—the company bought back shares during the quarter and continues investing in capacity expansion. When management puts capital to work at these levels, it signals belief in sustained demand.

Valuation Perspective

Trading at roughly 18 times forward earnings with mid-teens growth doesn’t scream overvalued. Factor in the AI tailwinds, domestic manufacturing shift, and solar ramp, and the multiple feels reasonable.

Compare that to pure-play data center infrastructure names trading at 30-40 times earnings. This company offers similar exposure with diversification across display, environmental, and life sciences segments.

In my experience, the best investments combine growth visibility with reasonable valuations. This setup checks both boxes.

Risks to Consider

No investment is without risks. Display demand could remain soft longer than expected. Geopolitical tensions might disrupt supply chains. Competition in optical communications is fierce.

Yet the company’s technology leadership, patent portfolio, and customer relationships create meaningful barriers. The domestic production shift actually reduces certain risks that peers face.

Why We’re Raising the Target

Originally set at $93, we’re moving our price target to $95 per share. This reflects:

  1. Accelerated Springboard progress and raised internal targets
  2. Faster-than-expected data center growth
  3. Expanded domestic manufacturing footprint
  4. Strong free cash flow supporting buybacks and investment
  5. Multiple expansion potential as AI narrative gains traction

The buy rating remains firm. In fact, the post-earnings weakness provided an attractive entry point for new positions.


Looking ahead, 2026 feels like a pivotal year. The combination of AI infrastructure buildout, domestic premium device glass production, and solar market expansion could drive another leg higher.

Markets often overreact to short-term noise while underappreciating structural shifts. This feels like one of those moments. The fundamentals haven’t changed—the opportunity set has actually expanded.

For investors with a 12-24 month horizon, the current price levels offer compelling risk/reward. Sometimes the best opportunities come disguised as disappointments. This, I believe, is one of them.
