NEW YORK -- Dell ( DELL) posted earnings on Thursday that came in below analysts' forecasts but the PC maker's revenue topped estimates. Dell's Enterprise Solutions group booked a solid increase in revenue during the quarter, while hardware sales were dismal. The company posted adjusted earnings of 21 cents a share, falling short of analysts' estimates of 35 cents a share. Dell reported first-quarter revenue of $14.1 billion, a 2% decrease from the prior year, but higher than consensus expectations of $13.5 billion. The Enterprise Solutions group's successful first quarter threw weight behind activist investor Carl Icahn's bid to overtake Silver Lake Partners and founder Michael Dell's $13.65 a share offer to take the PC maker private. The numbers highlighted Icahn's argument that Dell's bid sharply undervalued the company's potential to become a serious enterprise computing company. Meanwhile, the poor performance in hardware sales during the quarter gave credence to Dell's argument that a turnaround can't occur under the harsh light of the public eye, where calls for spinoffs have grown louder.
