Microsoft announced a quarterly revenue of $21.46 billion for the quarter ended December 31, 2012. Operating income, net income, and diluted earnings per share for the quarter were $7.77 billion, $6.38 billion, and $0.76 per share. The Windows Division posted revenue of $5.88 billion, a 24% increase from the prior year period. Adjusting for the net deferral of revenue for the Windows Upgrade Offer and the recognition of the previously deferred revenue from Windows 8 Pre-sales, Windows Division non-GAAP revenue increased 11% for the second quarter. Microsoft has sold over 60 million Windows 8 licenses to date. Microsoft reaffirms fiscal year 2013 operating expense guidance of $30.3 billion to $30.9 billion.
“Our big, bold ambition to reimagine Windows as well as launch Surface and Windows Phone 8 has sparked growing enthusiasm with our customers and unprecedented opportunity and creativity with our partners and developers,” said Steve Ballmer, chief executive officer at Microsoft. “With new Windows devices, including Surface Pro, and the new Office on the horizon, we’ll continue to drive excitement for the Windows ecosystem and deliver our software through devices and services people love and businesses need.”
