The Chinese company paid US$2.9 billion for Motorola Mobility and $2.1 billion for IBM's x86 server business. Prior to the acquisitions, Lenovo typically reported strong earnings on continued PC demand in its home market.
The impact of the acquisitions was not unexpected. The Chinese PC maker has said its net profit will fall in the short-term, following the acquisitions last year.
During the quarter, Lenovo's net profit was $100 million, down from $158 million a year ago. Revenue, however, hit $11.3 billion, up 21 percent year over year, the company reported Thursday.
To fuel its future growth, the company has been expanding into mobile devices and the enterprise sector. Its purchase of Motorola Mobility, for example, will give Lenovo an instant foothold in smartphone markets such as the U.S.
The Motorola purchase has made Lenovo the world's third largest smartphone vendor, behind Apple and Samsung, according to research firm IDC. But the company still faces the challenge of making its smartphone business profitable.
Its business in smartphones, tablets, servers and other products now accounts for 37 percent of its revenue, the company said in its earnings statement. That figure is up from 17 percent points a year ago.
PCs, however, still remain the company's main business. It ranks as the world's largest PC vendor. During the fiscal year ended March 31, Lenovo shipped 60 million PCs, a new record for the company, and it has been steadily growing its market share in the U.S.
