On October 1, Corning rose 3.33% in regular trading, trading at $159.16/share, with turnover of $322 million. The rally was driven by continued bullish sentiment surrounding AT&T's multi-year agreement with Corning valued at over $3 billion, under which Corning will supply optical fiber and cable to support AT&T's network expansion.

The landmark order, initially announced on September 29, has served as a strong catalyst over multiple sessions, reinforcing Corning's dominant position in optical communications infrastructure. The deal's substantial scale has also helped alleviate market concerns over equity dilution stemming from a previously disclosed equity distribution agreement with Goldman Sachs for up to $2 billion in share sales, which had triggered a sharp selloff of over 13% in mid-September.

Broader sector strength provided additional tailwinds, with peer Coherent surging 10.16% during the session. Meanwhile, Corning's recent collaboration with Qualcomm and Lumentum showcasing high-density optical die-to-die interconnect solutions for AI scale-up systems at ECOC has further bolstered investor confidence in its AI data center optical communications outlook. The company is scheduled to report next quarter earnings on October 27.
