China's Lenovo said revenue rose 20% in its past fiscal year, helped by its purchase of Motorola last year as the PC maker diversifies into the smartphone market, but net profit growth slowed to just 1%.
The world's biggest personal computer maker said revenue reached $46.3bn for the year ending 31 March.
Revenue from the company's mobile business including Motorola increased 71% year-on-year to $9.14 billion, making up about a fifth of the revenue total.
But net profit was up only 1% at $829m owing to increased operating expenses, it said in a filing to the Hong Kong stock exchange.
That was slightly below the expected net average of $830.2 million by 26 analysts polled by Bloomberg News, which said it was the slowest net profit growth in five years.
The PC maker had seen its net profit rise 29 percent in the previous financial year, driven by record smartphone sales.
"The rise of new technology and market trends, particularly the social mobile Internet, has posed market opportunities and challenges as consumer behaviour is changing," the company said in the filing.
Smartphone shipments worldwide grew more than 50% year-on-year to 76 million "driven by aggressive business expansion in emerging markets outside of China from Lenovo brand products and strong growth of the Motorola brand products", it said.
The group's non-PC revenue contribution rose to 28% from 18% in the same period last year, while operating expenses were up almost 40% at $5.57 billion.
In its third quarter results published in February, Lenovo said mobile phone shipments had surged almost 80% thanks to its $2.9 billion purchase of Motorola from Google in October.
That buyout happened soon after Lenovo paid $2.3 billion for IBM's low-end server business as it looked to diversify beyond PCs.
