Corning's Q1 sales jump 18% as AI and solar demand surge
Corning Inc. reported first-quarter core sales of $4.35 billion, up 18% year-over-year, as demand for AI-related optical equipment and solar products accelerated. The company beat analyst expectations and extended its streak to eight consecutive quarters of year-over-year growth.
Optical Communications sales grew 36%, while the company's newer Solar business jumped 80% in the quarter. These two segments drove the overall revenue beat.
The company also finalized two additional large, multiyear customer agreements similar in size and scope to a recently announced up-to-$6 billion deal with Meta. Corning did not name the new hyperscaler customers.
What this means for sales teams
For sales professionals, Corning's results signal where enterprise spending is flowing. Hyperscalers are locking in long-term supply agreements for optical networking gear-the infrastructure that powers AI data centers. These aren't one-time purchases but multiyear commitments worth billions.
The deals reflect a shift in how major tech companies buy. Instead of spot purchases, they're signing extended contracts to secure supply chains for AI buildout. Sales teams selling infrastructure or components into this ecosystem should expect customers to ask about long-term capacity and pricing certainty.
Corning's solar business growth also matters. The 80% year-over-year increase suggests demand for solar-related manufacturing equipment and materials is accelerating-a different customer base than the hyperscalers, but with similar growth trajectories.
Financial performance
Core earnings per share grew 30% year-over-year to $0.70. Core operating margin expanded 220 basis points, and core gross margin grew 120 basis points. The company's return on invested capital increased 190 basis points.
For the second quarter, Corning expects core sales of approximately $4.6 billion, up 14% year-over-year, and core EPS in the range of $0.73 to $0.77, up 25% year-over-year.
The company will take a $30 million hit in Q2 due to an extended maintenance shutdown at its solar wafer facility while it upgrades production equipment. This is included in guidance.
What's next
Corning plans to extend its Springboard growth plan through 2030 and will introduce a new Photonics Market-Access Platform at an investor event on May 6. The company said it will detail the technical and demand trends driving its AI product development.
For sales teams tracking enterprise spending, Corning's performance suggests the AI infrastructure build is moving from planning into execution-and customers are willing to commit capital and lock in supply agreements to make it happen.
