Corning (GLW) stock is moving higher today after the company announced a multi-year, $3 billion fiber and cable supply deal with AT&T. The agreement, which aims to expand AT&T’s network to meet surging data demand, has driven the stock to a session high of $160.56. The deal builds on a similar arrangement between Corning and Verizon earlier this month and underscores the growing need for high-density optical fiber as household data usage increases.

What Happened

The partnership with AT&T will see Corning supply fiber and cable to support the mobile carrier’s network expansion. The companies cited rising data consumption, with household usage projected to reach 2, 2.5 terabytes by 2030. The deal is expected to span multiple years and aligns with Corning’s broader strategy to capitalize on infrastructure demand driven by AI and broadband growth. The stock opened with a 0.5% gap and has risen more than 5% in early trading. The move follows a broader trend of telecom providers securing fiber supply agreements to meet the needs of a data-driven economy.

What The Data Shows

The stock is trading at $160.03, up from an open of $152.36. The session volume of 1.7 million shares is significantly below the 3-month average, indicating a relatively quiet start to the day. The stock is currently within its 52-week range of $77.39 to $271.78 and has risen 1.2% over the past eight sessions. Corning’s fundamentals remain strong, with a revenue growth of 19.4% in the trailing twelve months and a P/E ratio of 69.9. The stock has also hit 15 fresh 52-week highs in the last session, reflecting continued investor confidence.

What To Watch

The stock will likely remain in focus as more details about the AT&T partnership emerge. Investors should also monitor the breadth of coverage in the coming days, as the initial 11 stories from 10 sources suggest strong media interest in the deal.
