Apple's (AAPL) first quarter 2019 earnings results, by the numbers: Apple said Tuesday that its sales for the all-important holiday quarter hit $84.3 billion. The figure was slightly better than Apple had warned investors to expect earlier this month, but nonetheless represented a 5% decline from the same quarter a year ago.

The sales decline was driven by a dip in iPhone sales, which Apple CEO Tim Cook previously said was primarily due to a slowdown in China. Apple's iPhone revenue for the quarter fell 15%, to $51.98 billion.

Apple's sales in China also fell considerably. It reported revenue in the region of $13.17 billion, down from $17.95 billion in the same period a year ago.

Apple stock initially rose as much as 3% in after hours trading Tuesday following the report.
