Hewlett-Packard Co said its quarterly revenue fell over the year mainly due to the weak enterprise demand, as the company is getting ready to split off enterprise services from its computer and printing units next year. Sales fell 2.5 percent in the fourth quarter to $28.41 billion, from $29.13 billion a year earlier, HP said on Tuesday. Profit declined 5.7 percent to $1.33 billion, or 70 cents a share, compared with 73 cents a share a year ago.

HP's personal systems revenue was up 4% year over year with a 4.0% operating margin. Commercial revenue increased 7% and Consumer revenue decreased 2%. Total units were up 5% with desktops units down 2% and notebooks units up 8%.

The company's printing revenue was down 5% year over year with an 18.1% operating margin. Total hardware units were down 1% with Commercial hardware units up 5% and Consumer hardware units down 4%. Supplies revenue was down 7%.

HP's Enterprise Group revenue was down 4% year over year with a 14.8% operating margin. Industry Standard Servers revenue was down 2%, Storage revenue was down 8%, Business Critical Systems revenue was down 29%, Networking revenue was up 2% and Technology Services revenue was down 3%.

Enterprise Services revenue was also down 7% year over year with a 6.8% operating margin.

"I'm excited to say that HP's turnaround continues on track," said Meg Whitman, chairman, president and chief executive officer, HP. "In FY14, we stabilized our revenue trajectory, strengthened our operations, showed strong financial discipline, and once again made innovation the cornerstone of our company. Our product roadmaps are the best they've been in years and our partners and customers believe in us. There's still a lot left to do, but our efforts to date, combined with the separation we announced in October, sets the stage for accelerated progress in FY15 and beyond."

The company said last month it would split into two listed companies, separating its computer and printer businesses from its faster-growing corporate hardware and services operations, and eliminate another 5,000 jobs as part of its turnaround plan.
