Corning (GLW) After New AI Connectivity Deals Looks Undervalued But Is It Priced In

Listen to the news

Corning (GLW) has entered the AI plumbing conversation through two new collaborations that focus on high-density optical links. Both projects target the wiring challenges inside modern data centers.

For context, Corning’s share price has climbed 72.9% year to date to US$156.74, helped by recent AI connectivity headlines, even though the 90 day share price return is down 38.7% and longer term total shareholder returns over 3 and 5 years remain very large by comparison to those shorter moves.

Corning has already run hard on AI plumbing hopes, then pulled back sharply. Does that recent swing justify stepping in now, or does it argue for patience and a better entry before the numbers do more of the talking?

Most Popular Narrative: 18% Undervalued

On the current narrative, Corning is priced at $156.74 against an implied fair value of $191.40, so the gap between story and screen is already clear before digging into the drivers behind it.

Corning's Springboard plan aims to add more than $4 billion in annualized sales by 2026, driven by strong demand in Optical Communications and Solar sectors due to powerful secular trends, positively impacting revenue growth.

The company sees substantial growth in Optical Communications, particularly in innovations for Gen AI data centers, which are expected to drive incremental revenue and accelerate operating margin improvements toward 20% by the end of 2026.

See why 91 investors see Corning as 18% undervalued.

Result: Fair Value of $191.40 (UNDERVALUED)

Still, Corning’s reliance on non GAAP metrics and its exposure to tariff and trade shocks could quickly challenge today’s AI heavy narrative.
