Optical Sales Accelerate on AI Demand
Optical Communications remained the company’s largest growth engine, with sales rising 32% year over year to $2.07 billion. Segment net income surged 77% to $438 million, reflecting strong demand and favorable operating leverage.
Enterprise Networks drove the improvement as hyperscale customers expanded AI-related data center capacity. Corning also announced multiyear agreements with Amazon and NVIDIA, supporting further demand for optical fiber, cable and connectivity products. The NVIDIA partnership includes plans to increase U.S. optical connectivity manufacturing capacity tenfold and expand domestic fiber production capacity by more than 50%.
Solar Business Posts Sharp Growth
Solar revenues climbed 90% year over year to $438 million, making the segment the company’s fastest-growing operation. Sales also increased 18% sequentially as Corning continued to scale its polysilicon, wafer and module businesses.
The segment recorded a net loss of $7 million against a net income of $2 million a year earlier. Results were affected by an extended maintenance shutdown and equipment upgrade at the solar wafer facility. Management expects profitability to improve in the third quarter as production resumes and operating efficiencies strengthen.

Core net income increased 30% to $680 million. The stronger margin profile reflected higher sales volumes, a favorable business mix and improved scale. Core return on invested capital advanced 180 basis points to 14.9%, indicating better returns from the company’s asset base and growth investments.
On a GAAP basis, operating income rose to $698 million from $573 million. Selling, general and administrative expenses increased to $608 million from $515 million, while research, development and engineering expenses rose to $299 million from $276 million.

Cash Flow Strength Lends Support

Capital expenditures totaled $422 million. Cash and cash equivalents were $2.50 billion at June 30, 2026, while long-term debt stood at $7.76 billion.

The company also aims to reach $30 billion by the end of 2028 and $40 billion by the end of 2030, supported by AI infrastructure, solar expansion and deeper customer partnerships.
