Corning (GLW) is back in focus after announcing a multiyear partnership with Nvidia that aims to expand its U.S. optical connectivity manufacturing capacity tenfold, supported by a multibillion dollar Nvidia investment.

The Nvidia partnership lands on top of a strong run, with Corning’s share price up 10.32% over 30 days and 33.60% over 90 days. The 1 year total shareholder return of 307.31% and 3 year total shareholder return of roughly 6x point to powerful momentum that has invited both enthusiasm and valuation concerns.

With Corning trading within roughly 2% of the average analyst price target and some services flagging the stock as richly valued, the real question is whether the recent AI optimism leaves room for upside or whether markets already price in future growth.

Most Popular Narrative: 39.4% Overvalued

At a last close of $194.05 versus a narrative fair value of $139.21, Corning is framed as richly priced, with the story hinging on aggressive AI and data center expectations.

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.

Curious how this growth story backs up such a rich price tag? Revenue rising fast, margins stepping higher, and a punchy future earnings multiple sit at the center of this narrative, with detailed assumptions on how AI data centers and solar demand reshape Corning’s earnings profile.

Result: Fair Value of $139.21 (OVERVALUED)

However, this story can be challenged if AI and solar demand disappoint or if tariffs and competition squeeze the 13.96% margin that underpins current assumptions.
