The call will see the final results of Apple’s last 2009 quarter, as the company reportedly moves to beef up its product offering with improvements in its iMac range as it enters the first quarter of the 2010 financial year, which customarily begins between September 28-30. New iMacs are expected in early October. Speaking during the most recent Q3-09 call, Apple CFO, Peter Oppenheimer, predicted revenue in this quarter in the range of $8.7-8.9 billion. “Looking ahead to the fourth fiscal quarter of 2009, we expect revenue in the range of about $8.7 billion to $8.9 billion,” he said, “and we expect diluted earnings per share in the range of about $1.18 to $1.23.” Apple’s last quarter was a success. It posted revenue of $8.34 billion and a net quarterly profit of $1.23 billion, or $1.35 per diluted share. Record results for the company in a non-holiday quarter. The results aren’t expected to see Apple apply the recently revised GAAP rules which will now allow the company to note revenues from iPhone and Apple TV sales in the quarter they take place. It’s likely the company will require more time to put new systems in place for new form reporting on these. The results will be revealed during a conference call, which will be made available for listening here.
