(Reuters) – Chinese mobile security software maker NQ Mobile Inc estimated revenue in the first three months of the year would exceed its forecast of $75-$76 million due to strength in its enterprise business. NQ provides mobile devices as well as content and application management services through its NationSky enterprise business. Its customers include the Agricultural Bank of China and the National Bureau of Statistics of China. Enterprise sales across NQ’s product and services divisions brought in 14 percent of the company’s revenue of $91.8 million in 2012.
