Japan's Fujitsu swung back to profit in the three months to December thanks to brisk sales in PCs and networking services for public and business customers, as well as a weaker yen, the company said Thursday.

The sprawling IT conglomerate said it logged a net profit of 12 billion yen ($117 million) in the third quarter of the fiscal year, against an 80.8 billion net loss a year earlier.

Revenue rose more than 14 percent to 1.2 trillion yen, compared with 1.05 trillion yen 12 months earlier

"Sales of system integration services increased, primarily in the public sector and financial services sector," Fujitsu said in a statement.

"Sales of PCs also grew, primarily to enterprise customers. Sales of car audio and navigation systems in North America increased."

Fujitsu president Masami Yamamoto said in the statement: "We expect to maintain this momentum for the rest of the fiscal year, and will continue to pursue ongoing structural reforms in the (microchip) device business and businesses outside Japan."

In the nine months to December, the company, which has been overhauling a troubled semiconductor division, posted 2.3 billion yen in net profit, recovering from a 95.2 billion net loss a year earlier.

It slightly upgraded its forecast for the year to March, expecting 4.68 trillion yen in sales and 45 billion yen in net profit.
