Corning Incorporated (NYSE:GLW) reported better-than-expected second-quarter earnings on Tuesday, but investors focused on weaker-than-anticipated guidance for the third quarter, sending the specialty glass and materials manufacturer’s shares down 11.2%.
The company posted adjusted earnings per share of $0.78, exceeding the analyst consensus estimate of $0.75. Quarterly revenue reached $4.74 billion, ahead of expectations of $4.62 billion and up 17% from $4.05 billion in the same period last year.
Third-Quarter Forecast Falls Short of Market Expectations
Despite delivering a solid quarterly performance, Corning’s outlook for the third quarter failed to impress investors.
The company expects adjusted earnings per share of between $0.85 and $0.89 during the third quarter. The midpoint of $0.87 was viewed as slightly below Wall Street expectations.
Corning also forecast third-quarter revenue in the range of $4.9 billion to $5.0 billion. The midpoint of $4.95 billion came in below the analyst consensus estimate of $5.0 billion.
The weaker guidance overshadowed the company’s quarterly results and updated long-term growth ambitions, contributing to the sharp decline in the share price.
Optical Communications and AI Demand Drive Growth
Optical Communications remained Corning’s strongest-performing business during the quarter, with revenue rising 32% year over year to $2.07 billion.
Within the segment, Enterprise Networks revenue surged 65%, supported by robust demand for products linked to generative artificial intelligence infrastructure.
The Solar business also delivered strong top-line growth, with revenue climbing 90% to $438 million. However, the segment recorded a net loss of $7 million following an extended maintenance shutdown.
“In the second quarter, we delivered outstanding results, and we upgraded our Springboard Plan to grow sales to an annualized 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,” said Wendell P. Weeks, chairman and CEO.
Strategic Partnerships and Margin Expansion Support Long-Term Outlook
During the quarter, Corning announced a multiyear, multibillion-dollar agreement with Amazon to supply optical fibre and connectivity solutions.
The company also unveiled a long-term partnership with NVIDIA aimed at increasing US-based optical connectivity manufacturing capacity by tenfold.
Operational performance continued to improve, with adjusted gross margin expanding by 120 basis points to 39.6% and adjusted operating margin rising by 190 basis points to 20.9%.
Corning generated adjusted free cash flow of $1.42 billion during the quarter, reflecting continued strength in cash generation despite the softer near-term guidance.
