06:11 AM EDT, 05/02/2025 (MT Newswires) -- Apple ( AAPL ) Chief Executive Officer Tim Cook said the company estimates an additional $900 million in costs in fiscal Q3 June quarter "assuming the current global tariff rates, policies, and applications do not change for the balance of the quarter, and no new tariffs are added."

Cook went on to add in the company's fiscal Q2 earnings conference call late Thursday that the "estimate should not be used to make projections for future quarters, as there are certain unique factors that benefit the June quarter."

Responding to a question from Amit Daryanani, an analyst at Evercore ISI Institutional Equities, seeking further clarification on what the Apple ( AAPL ) CEO meant by "unique factors," Cook said "I wouldn't want to go through all of them."

"But as an example, the build ahead that is -- I mentioned earlier that's in the manufacturing purchase obligations is -- were helpful," Cook added.

Apple ( AAPL ) Chief Financial Officer Kevan Parekh said the company expects gross margins of between 45.5% and 46.5% in the June quarter, including the estimated impact of the $900 million of tariff-related costs.

"I wouldn't want to predict the mix of production in the future, but I wanted to give you clarity for the June quarter of where the country of origins are, so you can use that for your modeling," Parekh said on the call.

Additionally, Cook told call participants that 19 billion chips for its products are coming from 12 states in the US.

"We also have glass coming out of the US, and the Face ID module, and loads of chips," Cook said. "We're excited about bringing more production to the US."

Apple's ( AAPL ) shares were down 2.7% in premarket activity on Friday.
