No more cell phones from Motorola?

news analysis Maybe Carl Icahn was right about Motorola.

The company, which practically invented the cell phone market in the '80s, is considering spinning off its beleaguered handset business in an effort to revive the business, Motorola said Thursday.

In a press release, the company said it was considering a "structural realignment" to kick-start its mobile-device business, which has seen its global market share plunge to 12 percent from more than 20 percent market share a year ago. The main problem has been Motorola's inability to come up with new handsets to follow the once highly popular Razr.

Last week, the company told investors it would take longer than expected to turn around its troubled cell phone business. And it warned that revenue and market share would likely decline further in the first quarter.

Icahn, the activist investor who has been critical of Motorola's management for more than a year, has encouraged the company to break up, separating the handset division.

"For many months I have been publicly advocating the separation of Mobile Devices from Motorola's other business," he said in a statement. "And I am pleased to see that Motorola is finally exploring that proposal."

Icahn, who lost his bid to win a Motorola board seat last year, said Thursday he still plans to go through with yet another proxy fight this year to win board seats.

"We have previously informed Motorola that we expect to run a slate of directors for the upcoming annual meeting," he said. "And this announcement by Motorola will not deter us from that effort--we believe Motorola is finally moving in the right direction, but certainly still has a long way to go."

Wall Street reacted positively to the news of a possible split in the company and boosted Motorola's share price 10 percent to US$12.65 in after-hours trading. But some industry analysts say that simply selling the handset division could be a bad idea for the company, which has spent billions of dollars over the past several years building its consumer brand.

"The question is if you sell off the handset business, what's left?" said Iain Gillott of iGillott Research. "It doesn't make sense for them to have spent so much money developing their consumer brand if they're going to use it to sell set-top boxes and emergency radios."

One-hit wonder?
