Apple Chief Executive Officer Tim Cook joined President Donald Trump in the Oval Office to unveil an expanded domestic spending plan that will take the company’s U.S. outlays to roughly $600 billion over the next four years—$100 billion more than the commitment Apple made in February. Branded the American Manufacturing Program, the initiative is designed to deepen the iPhone maker’s U.S. supply chain and create tens of thousands of jobs. The pledge comes as the White House threatens to impose a 100 percent tariff on imported chips and semiconductors. Trump said firms that manufacture, or commit to manufacture, in the United States will be exempt and singled out Apple as a beneficiary. The concession spares the company from steep new levies while it continues to diversify final assembly, including production shifts to India made during earlier rounds of tariff pressure. Apple said it will source all iPhone and Apple Watch cover glass from Corning’s factory in Kentucky, expand chip partnerships with Texas Instruments in Texas and Utah, and become the anchor customer for Taiwan Semiconductor Manufacturing Co.’s new plant in Arizona. The outlays also cover additional data-centre capacity in North Carolina, Iowa, Nevada and Oregon and funding for an Amkor packaging facility in Arizona. To mark the occasion, Cook presented the president with a one-of-a-kind glass disc mounted on a 24-karat-gold base crafted from U.S. materials.
