Ariba(R), Inc. (Nasdaq:ARBA), the leading spend management solutions provider, today announced that it has again been named to the Supply & Demand Chain Executive Top 100. An annual measure designed to recognize companies that are leading the way in supply and demand chain transformation, the list highlights providers of supply chain services and technologies who are at the forefront of innovation. Ariba has been among the Supply & Demand Chain Executive 100 since 2003.

"The corporate executives and line-of-business leaders who read Supply & Demand Chain Executive want to know not only what the state of the art is today, but what will be the cutting edge of supply chain transformation and enablement tomorrow," said Andrew K. Reese, editor of Supply & Demand Chain Executive. "Our goal with this year's '100' is to highlight a broad range of innovations taking place in the theory and practice of supply chain transformation and identify providers who are addressing the needs of companies of varying sizes, and assisting in the transformation of a diverse mix of the functions that make up the supply chain."

Ariba was selected to the 2006 Supply & Demand Chain Executive 100 on the basis of its history of innovation, its continued commitment to advancing supply chain transformation and enablement and its track record of helping companies large and small deliver bottom-line results.

Ariba created spend management and has continued to lead and drive the discipline forward through its comprehensive range of solutions that combine technology, commodity expertise and services to help companies manage the entire procurement process from end-to-end.

"Ariba realized early on that technology alone would not be enough to transform procurement," said Kevin Costello, Chief Commercial Officer, Ariba. "From the outset, we have focused on enabling the people, processes and technology that companies need to move beyond simply automating the purchasing process and bring procurement science to every dollar of spend to lower their total costs and achieve operational excellence. We are pleased that the editors of Supply & Demand Chain Executive have recognized our efforts."
