NEW YORK — Shares of Nokia Corp. tumbled in premarket trading Wednesday after the Finnish mobile phone maker warned that fierce competition has driven its second-quarter sales and margins well below Wall Street expectations.
Share prices neared 52-week lows Tuesday, with a raft of industry analysts adjusting estimates for the company going forward. Before the market opened, shares had fallen below that range.
On Tuesday, Nokia said that second-quarter net sales in its key devices and services unit will be "substantially" lower than its earlier forecast of $8.8 billion to $9.5 billion. Operating margins will be well below its forecast of 6 percent to 9 percent, the company said.
Nokia withdrew all 2011 financial targets.
