The company reported revenue in the fourth quarter of its 2013 fiscal year of $37.5 billion, up from $35.97 billion a year earlier. That number topped analysts' estimates of $36.84 billion and Apple's own guidance from last month of around $37 billion.
"We're pleased to report a strong finish to an amazing year with record fourth-quarter revenue, including sales of almost 34 million iPhones," said Tim Cook, Apple's chief executive, in a news release.
Apple had said revenue probably would fall at the higher range of its guidance of $35 billion to $37 billion after the company reported it sold a record 9 million new iPhones during the first weekend they were available.
Apple also said it had net income of $7.5 billion, down from $8.2 billion for the same quarter last year. Earnings per share fell to $8.31 from $8.76 a year earlier. Still, that topped analysts' consensus estimate of $7.93.
The results were driven by sales of 33.8 million iPhones, compared with 26.9 million in the year-earlier quarter. That increase of 26% is below the 58% rate of growth in iPhone sales the company posted a year earlier.
Perhaps more importantly to Wall Street, Apple said it expected revenue of $55 billion to $58 billion for its current quarter, which ends Dec. 31. That range would be a bit above the consensus estimate of $55.65 billion that analysts had been projecting for the crucial holiday season.
That projection apparently didn't please investors who sent Apple's stock tumbling in after-hours trading down $11.69, or 2.21%, to $529.88. The stock had closed in regular trading up $3.92, or less than 1%, to $529.88.
Apple is scheduled to discuss its results in a conference call at 2 p.m. Analysts will be looking for more information about whether Apple can make enough of its iPhone 5s to meet demand, and when the iPad Mini with a Retina display might be available.
