Apple Inc. reported its fastest quarterly revenue growth in more than three years, easily topping Wall Street estimates, after demand picked up for the iPhone and products in China.

Apple may be the tech company most exposed to the Trump-era global tariffs, with the majority of its iPhones still manufactured in China. But the company calmed Wall Street’s concerns with its latest financial results, which showed a surge in iPhone sales. CEO Tim Cook also laid out a roadmap to ease the impact of levies.

The results came at a precarious time for the company long seen as Big Tech’s safest bet. Beyond the tariff threats facing its manufacturing hubs China and India, Apple has been slow to move on artificial intelligence technology that its software and devices rivals have embraced as their next big growth driver.
