Nokia and up to three other potential bidders are interested in buying Palm Incorporated, which could be sold for some $2 billion as early as this week. Based on unidentified sources, Unstrung.com believes Palm’s management would prefer a private equity buyer and the technology site speculated that Texas Pacific Group and Silver Lake Partners were among the private equity firms interested. Another possible bidder for Palm may be Motorola Incorporated. Unstrung said the company would likely sell for more than $20 a share. It had 102 million shares outstanding as of December. Sources have previously told Reuters that Palm hired Morgan Stanley to pursue a buyer. Unstrung said that Morgan Stanley wanted to wrap up a deal by Thursday, when Palm is scheduled to report quarterly results.
