Combination Extends Aribas On-Demand Spend Management Leadership and Expands Presence in Mid-Market

SUNNYVALE, Calif. & ATLANTA--()--Ariba, Inc. (Nasdaq:ARBA) today announced that it has signed a definitive agreement to acquire Procuri Inc., a privately-held provider of on-demand supply management solutions. With the acquisition, Ariba extends its position as the leading provider of spend management solutions to companies of all sizes and accelerates its traction in the rapidly growing mid-market.

Under the terms of the agreement, Ariba will deliver $93 million in consideration at closing, consisting of equal amounts of cash and stock, of which $14M of the cash will be placed in escrow to secure indemnity obligations of Procuri stockholders. Ariba will also pay off approximately $8 million of Procuris debt. The transaction, which is subject to customary closing conditions and regulatory approvals, is expected to close in the first quarter of Aribas fiscal year 2008, ending December 31, 2007. The definitive agreement has been approved by both companies' board of directors.

Ariba has been very successful in its shift to a Software as a Service (SaaS) business model, growing year over year subscription software backlog by 60% in the past quarter. This acquisition will accelerate our growth, give us scale in our on-demand business and strengthen our position in the fast growing mid-market, said Bob Calderoni, CEO, Ariba. Procuri has proven its ability to sell on-demand solutions to growing enterprises and has built an impressive list of customers. We can leverage this customer base and experience along with our solutions to further penetrate and lead the fastest growing segment of the spend management market.
