Corning reported a 44% year-over-year increase in third-quarter 2026 Optical Communications revenue to $2.38 billion, driven by demand for optical connectivity in AI data centers. Enterprise Networks sales jumped 84%, while sales of products for generative AI applications more than doubled.

Across all its businesses, Corning reported strong third-quarter 2026 financial results, with core sales increasing 19% year over year to $5.08 billion and GAAP revenue rising 18% to $4.86 billion. Core earnings per share climbed 36% to $0.91, reflecting revenue growth and improved operating efficiency. Core gross margin expanded 150 basis points to 40.5%, while core operating margin improved 310 basis points to 22.7%. The company generated $661 million in adjusted free cash flow while investing approximately $545 million in capital expenditures to support manufacturing capacity and future growth. Looking ahead, Corning projects fourth-quarter core sales of $5.2 billion to $5.3 billion and core EPS of $0.96 to $1.00, positioning the company for continued year-over-year growth as demand for optical connectivity and other advanced materials expands.

Optical Communications segment net income rose 80% to $532 million from $295 million a year earlier. Revenue increased 15% sequentially from $2.07 billion in the second quarter.

Enterprise Networks generated approximately $1.53 billion in quarterly revenue. Carrier Networks grew 4% to approximately $854 million, supported by data center interconnect deployments. Chairman and CEO Wendell Weeks said generative AI product sales more than doubled during the quarter.

Corning’s overall third-quarter core sales increased 19% to $5.08 billion, while core EPS rose 36% to $0.91. GAAP revenue was $4.86 billion, up 18%. Core gross margin expanded 150 basis points to 40.5%, and core operating margin increased 310 basis points to 22.7%.

Long-Term Agreements Support Manufacturing Expansion

Corning secured four long-term, multibillion-dollar customer agreements during the third quarter, including commitments from Verizon and AT&T. The company recently announced a $585 million expansion of its Wilmington, North Carolina, optical fiber manufacturing campus, expected to add 414 jobs over five years.

Corning invested approximately $545 million in capital expenditures during the quarter and generated $661 million in adjusted free cash flow.

Springboard Targets $40 Billion Annualized Sales by 2030

Corning’s Springboard growth plan targets an annualized sales run rate of $30 billion by the end of 2028 and $40 billion by the end of 2030. For Q4 2026, Corning forecasts core sales of $5.2 billion to $5.3 billion and core EPS of $0.96 to $1.00.

Analysis

Corning’s third-quarter results underscore how AI infrastructure investment is translating into accelerating demand for optical connectivity. The 84% growth in Enterprise Networks, compared with 4% growth in Carrier Networks, highlights the expanding role of fiber and high-density connectivity inside hyperscale data centers. As GPU clusters grow larger and AI workloads become more distributed, additional switching layers, higher aggregate bandwidth, and increasing optical port counts can drive fiber consumption beyond the growth rate of accelerator shipments. The more than doubling of generative AI product sales suggests that Corning is capturing an increasing share of this infrastructure investment.

Equally significant is the improvement in profitability. Optical Communications segment net income increased 80% to $532 million, representing approximately 22.4% of segment revenue, compared with 17.9% a year earlier. Corning is supporting this growth with multibillion-dollar customer agreements and expanded manufacturing capacity, including its recently announced $585 million investment in Wilmington, North Carolina. These commitments provide greater visibility into future demand while supporting domestic optical fiber production. The key indicators ahead will be whether Enterprise Networks maintains its growth trajectory, how quickly new manufacturing capacity comes online, and whether optical profitability continues to improve as AI deployments scale.
