Apple Inc. reported its fourth-quarter earnings, surpassing Wall Street's expectations, primarily driven by strong sales of the iPhone 16. The company generated $46.22 billion in revenue from iPhone sales during the quarter, alleviating concerns regarding the performance of its flagship product. However, revenue from other segments, including Mac, iPad, and services, fell short of analyst forecasts. Despite the positive news surrounding iPhone sales, Apple's stock experienced a dip due to a lower net income attributed to a one-time charge. Investors are now closely monitoring the initial sales performance of the iPhone 16 to gauge its potential impact on future earnings.
