Corning CEO Wendell Weeks stated that the company's tariff immunity is due to 90% of its U.S. revenue being generated by U.S.-origin products, with only 1% of U.S. sales sourced from Chinese factories. The company's stock (GLW) has surged 93% year-to-date, supported by Q2 core EPS of $0.78, which beat consensus, and 32% growth in Optical Communications revenue.
