Corning Jumps 11% After Bullish Analyst Signals on Tight Fiber Market

Overview

• Corning shares climbed about 11% after a Zacks upgrade to Buy and a UBS Buy reiteration tied to fresh industry checks.
• UBS kept a $171 price target following the Optical Fiber Communications conference, where participants described fiber as a seller’s market with scarce supply.
• The supply pinch points to firmer prices and clearer revenue visibility for Corning’s optical-communications unit that supplies data centers.
• The Zacks consensus for 2026 earnings per share has increased 3.3% over three months to roughly $3.10, reflecting a brighter profit outlook.
• UBS heard mixed timelines for swapping copper for fiber inside AI server racks, and Nvidia’s roadmap still funds both, leaving the speed of any upside uncertain.
