Corning Experiences Significant Stock Surge Amidst Major Connectivity Deals
On Tuesday, March 10, 2026, Corning Inc. (NYSE: GLW) shares demonstrated a robust performance, initially climbing 0.68% to $137.15 in after-hours trading, following a substantial 5.56% increase during the regular session, closing at $136.22. This upward trajectory is closely linked to a monumental announcement from AT&T Inc. (NYSE: T).

This partnership is crucial for AT&T's broadband expansion efforts, directly positioning Corning at the forefront of this extensive infrastructure project. Beyond its collaboration with AT&T, Corning also secured a substantial multi-year deal worth up to $6 billion with Meta Platforms (NASDAQ: META) in January 2026. Under this agreement, Corning will provide optical fiber, cable, and connectivity solutions for Meta’s advanced data centers across the U.S.

The company's Relative Strength Index (RSI) stands at 53.23, indicating a moderate momentum. Over the preceding 12 months, the large-cap stock has surged impressively, recording a gain of 202.64%. Currently, GLW’s stock is trading approximately 79.27% above its 52-week low, placing it firmly in the upper echelons of its annual trading range. Benzinga’s Edge Stock Rankings further highlight Corning’s strong Momentum, ranking it in the 96th percentile, which suggests a positive price trend across various timeframes.
Corning’s recent stock performance is a vivid illustration of how strategic partnerships and large-scale infrastructure investments can significantly influence a company’s valuation.
