Corning Incorporated’s first-quarter earnings, reported April 28, 2026, showed strong demand for AI and new solar products that boosted margins and led the company to raise its near-term core outlook.
Quarter Results and Margins
Corning said in a Form 8-K that its core sales rose 18% year-over-year to $4.35 billion, excluding about $200 million of one-time adjustments. Core earnings per share (EPS) increased 30% to $0.70. The company reported a core gross margin of 39.1%, up 120 basis points year-over-year, and a core operating margin of 20.2%. Operating cash flow reached $362 million, with adjusted free cash flow at $188 million.
On a generally accepted accounting principles (GAAP) basis, sales rose 20% to $4.14 billion, while net income doubled to $371 million, or $0.43 per share, from $157 million, or $0.18 per share, a year earlier. Corning beat consensus estimates on core sales and core EPS but missed on GAAP sales and GAAP EPS, reflecting differences in core and GAAP definitions across analyst estimates.
AI and Solar Drivers
Optical Communications sales grew 36% year-over-year, with segment profit rising roughly in line. Solar sales surged 80%, driven by expanded shipments of new products. Corning finalized two additional hyperscale customer agreements similar in size and duration to its multiyear, up-to-$6 billion contract with Meta, signaling larger commercial commitments.
The company reorganized its reporting segments in the first quarter, grouping businesses into Optical Communications, Glass Innovations, Automotive, and Solar, with other activities classified under Life Sciences/Emerging Growth.
Guidance and Springboard Progress
Corning forecast second-quarter core sales of about $4.6 billion and core EPS between $0.73 and $0.77. This outlook includes roughly $30 million in additional expenses from an extended maintenance shutdown at its solar wafer facility.
Management described the quarter as progress under its Springboard plan compared with the fourth quarter of 2023, with core sales up 33%, core EPS up 79%, core operating margin improved by 390 basis points, and core return on invested capital (ROIC) up 470 basis points. Wendell P. Weeks, chairman and chief executive officer, said, “Our strong first-quarter results continued the powerful trajectory of our Springboard plan.”
