Apple Inc. (NASDAQ:AAPL)

The operating income demonstrates a consistent upward trajectory over the examined period, increasing from 1,650 million USD in 2005 to 123,216 million USD in 2024. Notably, the growth was particularly pronounced between 2009 and 2012, where figures surged from 7,658 million USD to 55,241 million USD. After a peak in 2015 at 71,230 million USD, operating income experienced some fluctuations, including a decrease in 2016, followed by gradual increases leading to a new peak in 2021 at 108,949 million USD. The last three years show some variability but remained elevated, ending with an increase to 123,216 million USD in 2024. This pattern suggests substantial expansion in core profitability with occasional compression, reflecting dynamic operational conditions or investments.

Net sales consistently rose from 13,931 million USD in 2005 to 391,035 million USD in 2024, indicating strong top-line growth. The trajectory is marked by rapid increases especially from 2009 onwards, doubling from 36,537 million USD in 2009 to 108,249 million USD in 2011, and continuing robust growth thereafter. There are slight decreases visible around 2016 and again in 2023, but overall the sales figures depict a clear long-term expansion in revenue generation capacity.

The operating profit margin shows an improving trend from 11.84% in 2005 to a peak level around 35.3% in 2012, highlighting increased efficiency or pricing power during this period. After reaching this high point, margins experienced a downward adjustment, stabilizing predominantly in the mid to high 20% range between 2013 and 2020. From 2021 onward, margins slightly rebounded to over 30%, implying some restoration in profitability relative to sales. This pattern suggests that while growth in sales and income was largely successful, the company faced challenges maintaining peak operational efficiency consistently, yet has managed to sustain strong margins overall.
