GLW Doubles Down On Long-Term Growth Targets

Corning CEO Wendell Weeks said that the company is entering a “new phase of accelerating growth” after delivering what he described as an outstanding second quarter.

The company upgraded its Springboard Plan and now expects to reach an annualized sales run rate of $20 billion by the end of 2026, $30 billion by the end of 2028, and $40 billion by the end of 2030.

Weeks added that Corning expects to deliver a 19% compound annual growth rate in sales from the fourth quarter (Q4) of 2026 through Q4 of 2030.

He also pointed to Corning's expanding partnerships with major technology companies as validation of its long-term strategy.

During the quarter, Amazon.com Inc. (AMZN) signed a multiyear, multibillion-dollar agreement for Corning's optical fiber and connectivity products.

Nvidia Corp. (NVDA) also announced a long-term partnership that will see Corning expand its U.S. optical connectivity manufacturing capacity tenfold and increase domestic fiber production by more than 50% to meet rising AI infrastructure demand.

Weeks said these partnerships provide “strong proof points” supporting the company's Springboard growth plan.
