Nokia, the world’s third-largest mobile equipment maker, has seen nothing in its business that would lead it to change its financial outlook, its chief executive said on Sunday. It is kind of business as usual,” Nokia CEO Rajeev Suri said in response to a reporter’s question during a press conference ahead of the Mobile World Congress trade show in Barcelona. In late January, the company said that for its mainstay Nokia Networks’ business, it expected net sales and operating margins in the first quarter to decline compared to the fourth quarter of 2014, typically a seasonally stronger quarter.
