Apple's gross margins and earnings per share were boosted by the tariff refunds the company received so far. Another $1 billion in tariff refunds are still unaccounted for. Apple's record-breaking quarter didn't need the help of the tariff refunds, but it does add some extra flair to the already outstanding results. Apple shared that its gross margin was 50.1% with a favorable impact of 2% provided by tariff refunds. Apple shared that it expects another 1% boost to revenue in the September quarter thanks to more tariff refunds.
