The program ropes in key partners like Corning GLW.N, which will produce all iPhone and Apple Watch cover glass in Kentucky, and GlobalFoundries GFS.O, which will manufacture advanced wireless and power management chips at its New York facility.
GLW up 7.6% and GFS up 8.5% premarket.

The tariff push cost Apple $800 mln in June quarter.
