Lenovo Group Ltd said on Tuesday its quarterly revenue hit $14.1 billion in October-December period, a 31 percent increase year-on-year.

Recently completed mergers of smartphone maker Motorola Mobility and IBM Corp's x86 server unit helped to boost the revenue, it said.

Yang Yuanqing, chairman and CEO of Lenovo, said: "This quarter, we are at the starting line of a new race, but the results show that we have the right strategy, we made the right acquisitions and we executed well globally, so I am confident we are ready to win."

Revenues generated in the North and South America area were $4.3 billion, up 88 percent year-on-year.

The region now contributes 30 percent of the company's worldwide revenue, Lenovo said.
