GLW: AI Fiber Demand May Prove Insufficient To Justify Elevated Expectations

Analysts have raised their price targets for Corning, lifting our fair value estimate from about $50 to roughly $70 per share. This follows a series of target hikes that cited stronger than expected performance in Display and Specialty Materials, along with growing conviction in long term Optical, fiber, and polysilicon driven growth tied to data center and AI demand.

Analyst Commentary

Street research has turned more constructive on Corning, with multiple firms lifting their price targets to reflect stronger than expected results in Display and Specialty Materials and an improving outlook for Optical and polysilicon related growth. Targets now range from the mid $70s up to just over $100 per share, with most analysts highlighting Corning's leverage to data center spending, artificial intelligence infrastructure, and ongoing transitions from copper to fiber.

Despite the generally positive skew, ratings remain balanced, with several Neutral or Equal Weight stances signaling that a portion of the recent upside is already reflected in the valuation. These more measured voices point to the need for continued execution in Optical and Solar to justify premium multiples and sustain the step up in long term earnings growth that more bullish forecasts imply.

More optimistic commentary emphasizes that Corning is well positioned across multiple secular growth vectors. Rising hyperscaler investment in connectivity, margin expansion in connector and fiber solutions, and incremental contributions from polysilicon are all cited as potential drivers of a higher earnings base into the second half of the decade.

At the upper end of the target range, certain banks argue that the market is still underestimating the magnitude and duration of Optical fiber demand tied to AI deployments, implying a structurally higher earnings growth profile than currently embedded in consensus. Others view Corning as a core beneficiary of data center buildouts over the next one to two years, with further upside as fiber penetration in data centers increases over time.

Still, the mix of ratings and language across recent notes indicates that the Street is not unanimously bullish, and that some of the expected acceleration in growth is contingent on resolving supply issues, sustaining demand, and maintaining discipline on capital allocation and margins.

Bearish Takeaways

• Bearish analysts are maintaining Neutral or Equal Weight ratings even as targets move higher, signaling concern that recent share price strength may already reflect much of the anticipated recovery in Display and Specialty Materials.
• Several notes emphasize that Optical remains the key driver of the current valuation, raising execution risk if ramp timing slips or near term demand for AI related networking equipment proves more volatile than expected.
• Cautious commentary highlights that growth in Solar and fiber dependent businesses must accelerate and remain durable to support elevated earnings growth assumptions, leaving downside if macro or supply constraints delay project rollouts.
• Some Bearish analysts prefer to see clearer evidence of sustained margin expansion and capital discipline across segments before assigning a higher multiple, underscoring concerns that near term beats could be more mix driven than structurally repeatable.
