In 2025, Apple, along with its suppliers, made a significant miscalculation regarding the market demand for the iPhone Air. This misstep has led to a substantial backlog of components, potentially incurring losses amounting to hundreds of millions of dollars. Despite Apple's generally robust sales performance, this particular incident has shed light on the company's less-than-perfect understanding of customer demand. Such a lapse could undermine the stability of its supply chain, with the chip inventory suffering particularly severe losses. (Here, "robust sales performance" is a more natural and commonly used English phrase to describe strong sales. Also, "shed light on" is a more idiomatic way to express revealing or exposing something. The sentence structure has been slightly adjusted for better flow and readability.)
