It has been about a month since the last earnings report for Corning (GLW). Shares have added about 23.2% in that time frame, outperforming the S&P 500.
Will the recent positive trend continue leading up to its next earnings release, or is Corning due for a pullback? Well, first let's take a quick look at its most recent earnings report in order to get a better handle on the recent drivers for Corning Incorporated before we dive into how investors and analysts have reacted as of late.
Corning Beats Q2 Earnings Estimates on Optical and Solar Growth
Corning reported second-quarter 2026 results with non-GAAP earnings of 78 cents per share, up 30% year over year and 2.6% above the Zacks Consensus Estimate. Core revenues of $4.74 billion increased 17% and surpassed the consensus mark by 2.9%.
Revenue growth was primarily led by Optical Communications and Solar segments. Enterprise Networks sales jumped 65%, supported by accelerating demand for generative artificial intelligence (AI) infrastructure. Core operating margin also expanded as higher volumes and improved execution strengthened profitability.
Optical Sales Accelerate on AI Demand
Optical Communications remained the company’s largest growth engine, with sales rising 32% year over year to $2.07 billion. Segment net income surged 77% to $438 million, reflecting strong demand and favorable operating leverage.
Enterprise Networks drove the improvement as hyperscale customers expanded AI-related data center capacity. Corning also announced multiyear agreements with Amazon and NVIDIA, supporting further demand for optical fiber, cable and connectivity products. The NVIDIA partnership includes plans to increase U.S. optical connectivity manufacturing capacity tenfold and expand domestic fiber production capacity by more than 50%.
Solar Business Posts Sharp Growth
Solar revenues climbed 90% year over year to $438 million, making the segment the company’s fastest-growing operation. Sales also increased 18% sequentially as Corning continued to scale its polysilicon, wafer and module businesses.
The segment recorded a net loss of $7 million against a net income of $2 million a year earlier. Results were affected by an extended maintenance shutdown and equipment upgrade at the solar wafer facility. Management expects profitability to improve in the third quarter as production resumes and operating efficiencies strengthen.
GLW Expands Core Margins and Profitability
Core gross margin improved 120 basis points year over year to 39.6%. Core operating margin expanded 190 basis points to 20.9%, while core operating income rose to $989 million from $770 million.
Core net income increased 30% to $680 million. The stronger margin profile reflected higher sales volumes, a favorable business mix and improved scale. Core return on invested capital advanced 180 basis points to 14.9%, indicating better returns from the company’s asset base and growth investments.
On a GAAP basis, operating income rose to $698 million from $573 million. Selling, general and administrative expenses increased to $608 million from $515 million, while research, development and engineering expenses rose to $299 million from $276 million.
Corning’s Other Segments Deliver Mixed Results
Glass Innovations generated sales of $1.46 billion, up 1% year over year. Segment net income increased 9% to $354 million, showing improved profitability despite modest revenue growth. Automotive sales advanced 2% to $471 million, while net income increased 4% to $82 million. The business also improved sequentially, with revenues rising 8% and profit increasing 17% from the first quarter. Life Sciences and Emerging Growth Businesses remained a weak spot. Revenues declined 15% year over year to $294 million, while the segment posted a net loss of $21 million compared with net income of $6 million in the prior-year quarter.
Cash Flow Strength Lends Support
Corning generated $1.72 billion in operating cash flow during the quarter, up from $708 million a year earlier. Adjusted free cash flow reached $1.42 billion compared with $451 million in the prior-year period.
Capital expenditures totaled $422 million. Cash and cash equivalents were $2.50 billion at June 30, 2026, while long-term debt stood at $7.76 billion.
Outlook
For the third quarter, management expects core sales between $4.9 billion and $5 billion, representing approximately 16% year-over-year growth. Core earnings are projected between 85 cents and 89 cents per share, implying growth of roughly 28%.
Corning continues to target an annualized sales run rate of $20 billion by the end of 2026 under its upgraded Springboard Plan. The company also aims to reach $30 billion by the end of 2028 and $40 billion by the end of 2030, supported by AI infrastructure, solar expansion and deeper customer partnerships.
