(Reuters) -Long seen as the safest Big Tech bet, Apple is heading into Thursday’s earnings with its business facing pressure from U.S. tariffs, tough competition in China and a high-stakes artificial intelligence race it has been late to enter. U.S. President Donald Trump has targeted the consumer electronics giant for its reliance on overseas manufacturing, threatening 25% tariffs on foreign-made iPhones. To limit the damage, Apple shifted production of U.S.-bound iPhones to India, further drawing Trump’s ire.
