Apple announced its fourth quarter report, with revenue of $89.5 billion, a decrease of 1% year-on-year, and net profit of $22.956 billion, an increase of 11% year-on-year. Among them, iPhone revenue was $43.805 billion, an increase of 2.7% compared to $42.626 billion in the same period last year. Except for iPhone, Apple's other hardware product revenue in the quarter decreased year-on-year. Apple CEO Cook stated that the sales of the iPhone 15 model are better than those of the iPhone 14 model, but the supply of Pro and Pro Max is limited, which affects the total revenue of the iPhone. These two products are expected to achieve supply and demand balance later, and the Mac business will also have a significant improvement. In this fiscal quarter, Apple's revenue in Greater China was $15.084 billion, a decrease of 2.5% compared to the previous quarter. Cook stated that he is very optimistic about Apple's long-term prospects in the Chinese market. Regarding AI, Cook stated that many of Apple's products have already used AI technology, and Apple is investing a considerable amount of funds into the field of generative AI.
