Executive summary
Corning (GLW) at $172.06 (as of 15 Jul 2026) trades at a large premium to any defensible intrinsic value; I estimate fair value near $98 with low confidence given a wide scenario range. Corning is a genuinely high-quality, 175-year-old materials-science franchise with five segments (Optical Communications 38% of sales, Display 23%, Specialty Materials 13%, Automotive 11%, Life Sciences 6%) and a real growth engine: AI data-center demand for optical fiber and connectivity. Its Springboard plan hit its $3bn incremental-sales and 20% core-operating-margin targets a year early and was upgraded to $5.75bn. Q1'26 revenue rose 20% YoY.
The problem is price, not business quality. The stock has re-rated to ~82x trailing and ~40x forward earnings, ~35x EV/EBITDA on 2026E EBITDA, and ~13x book. A reverse-DCF shows the price bakes in ~36% FCF CAGR for five years. My base DCF yields $58, peer comps ~$83, and a probability-weighted scenario set ~$98. Even my bull case (~$155) sits below the current price. The AI-optical story is real, but the market is discounting a sustained supercycle that must not only occur but persist and hold a premium multiple. Verdict: expensive — a premium to fair value.
