Corning (GLW) Stock Could Be 22% Undervalued On Fresh AI Connectivity News

Simply Wall St·09/30/2026 08:22:54
Listen to the news

Corning has seen its stock price climb sharply in recent years, so the obvious question now is whether the cash the business is expected to generate can really support where the shares trade today.

  • Over the past 3 years, Corning has returned about 4.6x, which puts a lot of weight on whether its future cash flows can live up to the expectations now embedded in the share price.
  • The recent collaboration with Lumentum and Qualcomm on high density optical interconnects for AI systems may support investor hopes for stronger long term cash generation from Corning's connectivity business.
  • If you'd rather focus on earnings, this one's for you. See why Corning's 72.0x P/E tells a different valuation story.

The issue now is whether a Discounted Cash Flow (DCF) view of Corning's cash flows lines up with where the stock currently trades.

If you are weighing Corning's AI connectivity story against other options, a focused stock screen is a useful second reference point, especially one built around 88 AI infrastructure stocks.

Is Corning Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) model here takes Corning’s projected free cash flows and brings them back to today’s dollars. On the latest twelve month view, the business generated about $2.5b of free cash flow, and the model assumes that figure grows over time rather than shrinking, with 2030 cash flow projections also in the multibillion dollar range.

Those recovering cash flow estimates leave the estimated intrinsic worth meaningfully above the current share price of $158.71. Because the recent AI focused collaboration with Lumentum and Qualcomm has already pushed the stock higher, the remaining gap suggests the cash flow story supporting Corning is still stronger than what the market price reflects today.
