Corning (GLW) Raised Guidance After AI Deals, Is The Pullback A Bargain?

Simply Wall St·10/31/2026 19:32:24
Listen to the news

Corning (GLW) has become a focal point for investors after reporting strong third quarter and year to date results, followed by higher guidance tied to optical communications demand and AI focused data center agreements.

Despite strong Q3 results and upbeat guidance, Corning’s recent momentum has cooled, with the share price down about 20% over the past month and 11% over 90 days even as the year to date share price return is 36% and the 1 year total shareholder return is nearly 40%.

Spot 54 AI infrastructure stocks that, like Corning’s optical business, are tied directly to AI data center buildouts and could be setting up their next major move.

Corning now pairs strong reported earnings and upbeat AI linked contracts with a sharp pullback in the share price. Does that reset leave the risk reward skewed toward buyers or toward investors taking some caution here?

Most Popular Narrative: 33% Undervalued

Corning’s most followed narrative pegs fair value at about $182.76, well above the last close of $123.31. This frames today’s pullback against a richer long term story grounded in AI infrastructure and energy transition spending.

The numbers imply that Corning’s current valuation treats the stock as if execution risk, equity issuance and mixed end market conditions fully offset the multibillion long term growth opportunities in AI data centers, U.S. solar and photonics. This underpins the view that the shares are undervalued.

See why 107 investors see Corning as 33% undervalued.

Result: Fair Value of $182.76 (UNDERVALUED)

Still, the Corning story can break if Springboard execution wobbles, or if further equity raises dilute earnings more than current AI and solar plans assume.

Another View: Corning Through The Earnings Multiple

That DCF style fair value near $182.76 paints Corning as undervalued, yet the current P/E of 49.4x is well above the US Electronic industry on 28.7x, and only slightly below a peer average of 63.7x and a fair ratio of 52.9x. Is that a bargain or just a lot of optimism priced in?
