Apple

2016 Revenue: $215.6 billion
One-year Revenue Change: -7.7%

Investors worried when, for the first time since 2001, the iPhone maker (aapl, +1.82%) reported an annual drop in revenue. That metric fell 7.7% in 2016, while profits slid 14.4% to $45.7 billion, as Apple struggled to compete with locally made phone brands in China. Still, many are hopeful that Apple’s next iPhone, variously known as the iPhone 8 or iPhone X, could come with major revamps that will lure new consumers. And despite a subpar year, Apple still boasts the highest profits of any company on the list.
