Summary
Q3 2026 results exceeded Corning’s guidance, and the company provided Q4 2026 outlook. Core sales rose 19% to $5.08B and core EPS rose 36% to $0.91, led by Optical Communications growth and Solar’s production ramp. Corning said the results show acceleration under its Springboard plan, which targets doubling its annualized sales run rate from $20B to $40B by the end of 2030. It also secured four long-term, multibillion-dollar customer agreements, including with Verizon and AT&T.

- Solar sales rose 37% to $436M as production ramped more slowly than anticipated. Corning said improving productivity should increase output and profitability; it is building toward a Solar revenue stream exceeding $3B. U.S. trade action under Section 232 improved the pricing environment and demand for U.S.-made solar products.
