The company said net profit was $253 million, down from $265 million a year prior due to ballooning operating expenses associated with two multi-billion dollar acquisitions completed in recent months.
The results beat expectations of $13.71 billion in revenue and $200 million in net profit, according to analysts.
The Beijing-based company acquired American phone brand Motorola for $2.91 billion and IBM's low-end server unit for $2.1 billion to expand its business beyond the declining PC market.
Lenovo, which closed the Motorola purchase in late October and included two months of Motorola's results in this quarter's earnings, touted the American handset brand's early performance and said it achieved "hyper growth" in emerging markets outside China.
Motorola sold more than 10 million handsets during the quarter, a company record, and its purchase by Lenovo made the combined company the world No. 3 smartphone maker with 6.6 percent market share, Lenovo said.
Total sales from the mobile division rose 109 percent to $3.39 bln, or a quarter of the company's sales.
Lenovo continued to consolidate its hold on the shrinking PC market, reaching a record 20 percent share during the quarter with sales of $9.15 billion. Shipments rose 5 percent compared to a 3 percent decline in the broader industry, with growth particularly strong in Eastern Europe, Lenovo said.
