Microsoft Corp. said Wednesday that its profit for the October-December quarter grew 10% from the same time last year as it works to capitalize on the huge amounts of money it has spent to advance its artificial intelligence technology.

The tech giant’s revenue was up 12 percent to $69.6 billion, but investors are showing their nerves after a long boom for tech stocks.

Microsoft on Wednesday reported profits of $24.1 billion in the recently ended quarter, but shares slid on worries over its vital cloud computing business. Microsoft revenue grew to $69.6 billion and the amount of money taken in by its "intelligence cloud" unit climbed to $25.

Microsoft reported that its flagship cloud computing business experienced a slowdown in growth amid constraints on data center supply.

Microsoft reported slower-than-expected growth in its crucial Azure cloud business on Wednesday despite beating estimates for overall quarterly revenue, sending its shares down 4% in extended trading.
