The Blackstone Group has walked away from the bidding for Dell, people involved in the negotiations said on Thursday.
The private equity giant â€" along with a separate bidder, the activist investor Carl C. Icahn â€" had been inspecting the books of the personal computer maker before deciding whether to make rival bids to the $13.65-a-share offer from the company’s founder Michael S. Dell and Silver Lake.
Blackstone decided to withdraw after discovering that Dell’s business is deteriorating faster than it previously understood, the people involved in the negotiations said.
Blackstone notified a special committee of Dell’s board on Thursday that it would no longer pursue its bid, these people said.
The personal computer industry has been grappling with falling prices and competition from smartphones and tablets. Its weakness was vividly illustrated by a report last week from the International Data Corporation that showed a sharp drop in global sales.
PC unit sales overall in the United States fell 12.7 percent in the quarter from a year ago, according to the report. At Dell, United States shipments were down 14 percent, while worldwide shipments were down more than 10 percent.
Blackstone, which had been working with the investment firms Francisco Partners and Insight Venture Partners, last month outlined an offer of more than $14.25 a share for control of Dell, but not for the whole company. Part of Dell, under that scenario, would still be publicly traded in what is known as a stub.
From the beginning, there had been dissension within Blackstone about whether it should pursue an offer, the people close to the firm said. Blackstone, worried that it would be used as a stalking horse, negotiated with Dell’s special committee to reimburse the firm for its costs related to pursuing an offer whether it ultimately made a binding bid or not.
The withdrawal of Blackstone leaves Mr. Icahn as the only potential rival to the $24,4 billion buyout proposal from Mr. Dell and Silver Lake.
On Tuesday, the Dell special committee announced that it had reached an agreement with Mr. Icahn that limits his ownership stake in the company while allowing him to contact other shareholders about a possible bid for the computer maker.
Mr. Icahn has previously outlined an offer of $15 a share for about 58 percent of the company. Under that plan, he would have a 24.1 percent stake in Dell.
“My affiliates and I expect to engage in meaningful discussions with other Dell shareholders, discussions that we believe will help to facilitate alternatives to the existing transaction with Michael Dell,†Mr. Icahn said in a statement on Tuesday.
Mr. Icahn and Blackstone were the only two preliminary bidders to emerge last month from the special committee’s process of soliciting potential alternatives in what is known as a “go-shop.â€
