Corning Stock Plunges 18% Despite Strong Earnings as Investors React to AI-Driven Growth Expectations
Corning (NYSE: GLW) shares tumbled 18% on Tuesday despite the specialty glass and optical connectivity company reporting another quarter of strong financial growth and raising its long-term growth ambitions.
The company delivered an impressive second quarter, with core sales rising 17% year over year to $4.74 billion and core EPS increasing 30% to $0.78. GAAP revenue also climbed 17% to $4.51 billion, while operating cash flow reached $1.72 billion. Profitability continued to improve, with core gross margin expanding to 39.6% and core operating margin increasing to 20.9%.
Growth was led by the Optical Communications segment, where sales jumped 32% to $2.07 billion. Enterprise Networks revenue surged 65%, driven by accelerating demand for AI infrastructure and high-speed optical connectivity. The Solar business also delivered standout performance, with sales soaring 90%, and management expects profitability to improve further in the third quarter.
Corning also announced major strategic developments, including new long-term partnerships with Amazon and NVIDIA. Amazon signed a multiyear, multibillion-dollar agreement for optical fiber and connectivity products supporting its expanding U.S. data center footprint, while NVIDIA partnered with Corning to expand U.S. optical connectivity manufacturing capacity tenfold and increase domestic fiber production by more than 50% to meet growing AI infrastructure demand.
Looking ahead, management issued another strong outlook. Third-quarter core sales are expected to reach $4.9 billion to $5.0 billion, representing approximately 16% year-over-year growth, while core EPS is projected at $0.85 to $0.89, up roughly 28%. The company also upgraded its long-term Springboard Plan, targeting an annualized revenue run rate of $20 billion by the end of 2026, $30 billion by the end of 2028, and $40 billion by 2030.
Despite the robust results, the sharp selloff likely reflects valuation and expectations rather than operating performance. Corning had rallied significantly ahead of earnings on enthusiasm surrounding AI infrastructure spending and its expanding partnerships with hyperscalers. Although the company delivered strong results and maintained an optimistic outlook, investors may have viewed the report as lacking additional positive surprises after the recent rally, prompting profit-taking and sending the stock sharply lower.
