Dell went private back in 2013 to reorganize without quite so much external pressure to perform. Now, however, it’s ready to go public once again. The company has unveiled a plan to buy its own tracking stock in a $21.7 billion deal that, in exchange, will offer a “new class” of public stock on the NYSE. The move won’t change Dell’s control over VMware (which it took when it bought EMC), but it could help Dell pay off its debt at a faster rate than it has so far.
