Corning (GLW) Stock Is Trending Overnight: Here's What Is Going On

Corning Inc. (NYSE:GLW) shares are trending on Tuesday night.

GLW edged higher in after-hours trading on Tuesday, rising 0.68% to $137.15.

The multinational technology company, which leverages expertise in glass science, ceramics and optical physics, closed the regular session up 5.56% at $136.22.

What's Driving The Rally?

The stock move came as investor interest spiked as AT&T Inc. (NYSE:T) unveiled a sweeping $250 billion U.S. connectivity investment commitment. Corning is a major supplier to AT&T.

AT&T CEO John Stankey announced the long-term investment commitment, citing a “most conducive” regulatory environment for infrastructure spending.

“Today, we’re committing more than $250 billion to increase U.S. connectivity competitiveness and expand access to AT&T’s leading fiber and wireless networks,” Stankey said.

Why Corning Is in Focus

The AT&T announcement carries direct supply-chain implications for the New York-based company.

In 2024, AT&T signed a multi-year purchase agreement with Corning to supply next-generation fiber, cable and connectivity solutions to expand AT&T's broadband footprint, which positions GLW as a critical upstream supplier.

In January, Corning also announced a multiyear deal worth up to $6 billion with Meta Platforms (NASDAQ:META) to supply optical fiber, cable and connectivity solutions for advanced U.S. data centers.
