8.6 million Lumia handsets sold by Microsoft during its fiscal third quarter
For the fiscal third quarter, Microsoft took in $1.4 billion in revenue from Lumia sales, a decline of 16% from a year ago. Microsoft said that the drop in revenue was due to a "higher mix of low royalty devices."
In addition, a strong performance by the Microsoft Surface Pro 3 in the third fiscal quarter led Microsoft to rake in $713 million for its Surface tablet division during the three month period that ended in March. That is a 44% year-over-year revenue increase for the company. Gross margins in this sector improved over the last year as increased sales of the higher priced Surface Pro 3 resulted in a higher price sales mix for Microsoft. As usual, the company did not disclose how many tablets it sold during the quarter. It did unveil the Microsoft Surface 3 on the last day of the three month period. The tablet doesn't launch until May 5th.
