During Thursday night’s earnings call, Apple (AAPL) CEO Tim Cook highlighted a string of milestones, including the company’s best-ever June quarter, with revenue reaching $109.4 billion. iPhone revenue surged 22% year-over-year to $54.3 billion, while Mac revenue climbed to a record $10.4 billion.

Beyond the financial results, Cook reaffirmed Apple’s commitment to US manufacturing, announcing plans to invest $600 billion in the United States over the next four years. The investment, which the company said includes the reinvestment of tariff-related funds, expands Apple’s long-term domestic manufacturing strategy.

As part of that effort, Apple has entered a new multiyear agreement with Broadcom (AVGO) under its American Manufacturing Program. The partnership is expected to contribute more than $30 billion in investment to build an end-to-end silicon supply chain and advanced manufacturing equipment in the United States.
