AI Summary

6.0
Neutral

Corning's AI-driven optical growth is reshaping it into an infrastructure play, but at ~56x earnings investors should only own or add if Optical Communications sustains high growth while materially expanding margins and ROIC; an AI-capex slowdown or weak earnings conversion could trigger a sharp de-rating.
