Quick Read – Corning CEO Wendell Weeks credits tariff immunity to a 90% domestic U.S. revenue base and only 1% of U.S. sales sourced from Chinese factories. – GLW has surged 93% year to date, backed by Q2 core EPS of $0.78 beating consensus and 32% Optical Communications revenue…
owth. – Corning’s customer-proximity model, which supplies Apple, Nvidia, and Amazon from U.S. factories, was built for innovation rather than tariff protection, but it ends up delivering both. – On Jim Cramer’s Mad Money on August 14, 2026, Corning (NYSE:GLW) Chair and CEO Wendell Weeks was asked a question that many retirement-focused shareholders have been asking themselves this year: are tariffs hurting the business? His answer was blunt. “No
Tariffs really have de minimis impact on us and that’s because of our philosophy,” Weeks said. “You got a sense of that today in the factory we locate close to our customers because the primary way that we win is with innovation.” The Two Numbers Behind the Claim Weeks then offered the specific figures that anchor the argument: “So as a result, let’s take the U.S. for example. 90% of our U.S. revenue is created by U.S. origin products. Only 1% of what we sell in the United States we make in China. So tariffs, because of our fundamental philosophy and our values tend not to have a significant impact on us.” Those two figures, attributed to Weeks on the broadcast rather than to a formal company disclosure, are the spine of the case.
If 90% of what Corning sells into the United States is made in there, and only 1% of U.S. sales originate from Chinese factories, the surface area exposed to Section 301 duties and the ongoing U.S.-China trade friction is narrow by construction. A Strategy That Wasn’t Designed as a Tariff Hedge The mechanism Weeks described predates the current tariff cycle. Corning has long placed plants near its largest customers and competed on product innovation rather than low-cost labor arbitrage.
