Corning jumps as Q1 core EPS rises 30% and Q2 outlook tops expectations
Corning shares are rising after the company reported Q1 2026 results showing 18% core sales growth to $4.35 billion and 30% core EPS growth to $0.70. Investors also focused on upbeat Q2 guidance calling for about $4.6 billion in core sales and $0.73–$0.77 core EPS, despite a planned solar-wafer maintenance shutdown cost.
1) What’s moving the stock
Corning stock is moving higher after the company posted a strong first-quarter 2026 update and paired it with a confident second-quarter outlook. The report highlighted accelerating demand tied to Optical Communications and the company’s newer Solar business, helping offset concerns about a planned operational interruption in solar-wafer production.

2) The key numbers investors are reacting to
Corning reported Q1 2026 core sales of $4.35 billion, up 18% year over year, and core EPS of $0.70, up 30%. For Q2 2026, Corning guided to core sales of about $4.6 billion (about 14% year over year) and core EPS of $0.73 to $0.77, which investors are treating as confirmation that momentum is extending beyond a single quarter.

3) What matters next (and the main risk to watch)
Management flagged that Q2 guidance includes an extended maintenance shutdown at its solar wafer facility, including a transition to a permanent power system and equipment work intended to raise throughput in future quarters; the company also quantified a planned expense tied to that shutdown. The near-term debate is whether the shutdown-related cost and any volume timing impact are more than offset by continued strength in Optical Communications, where the company cited strong year-over-year growth.
