Alibaba Group Holding missed analysts' estimates for quarterly sales on Friday, as lingering economic uncertainty sapped consumer spending in China and weighed on the e-commerce giant's domestic business.

Adjusted earnings before interest, taxes, depreciation and amortization declined about 4% to 47.33 billion yuan in its fiscal second quarter.

Alibaba Group, China's e-commerce, entertainment and tech giant, reported a 5% increase in revenues to RMB237 billion ($33.7 billion) in the three months to September. It reported a 63% increase in net profits to RMB43.
