Paul Demery

ROCKVILLE, Md., – May 24, 2006 – Manugistics Group, Inc. (NASDAQ: MANU), a leading global provider of synchronized supply chain and revenue management solutions, today announced that Circle K®, the second largest convenience store chain in North America, has selected Manugistics Retail Solutions to help ensure they have the right product, at the right store, at the right time in its Arizona Regional Division stores. The Circle K contract also marks Manugistics’ entry into the sizable and largely untapped convenience retail sector.

Circle K is a subsidiary of Couche-Tard which leads the Canadian convenience store industry and is the second largest independent convenience store operator not integrated with a petroleum company in North America. With more than 4,900 neighborhood convenience stores in its global network serving 25 million customers every week, the company wanted to improve its forecasting systems.

“The very nature of our business is ease and convenience,” said Circle K Bryant Santini, Senior Director, Information Services. “That means having a selection of food, beverages and merchandise available at our customers’ fingertips the moment they stop into our stores. Manugistics brings the breadth and depth of viable, innovative solutions we require to help us manage our goods so they are customer-ready – fresh and available.”

After a rigorous evaluation of retail merchandise replenishment solutions, Couche-Tard selected Manugistics’ Store Level Forecasting solutions because of its full demand management capabilities that integrate demand forecasting and replenishment in an easy-to-use client interface.

“Manugistics is delighted to expand our retail footprint into the convenience store industry with Circle K, one of the most recognizable companies in the industry,” said Manugistics Group Vice President of Retail Stephen Poplawski. “By applying our knowledge and experience from other retail segments, Manugistics is ideally positioned to deliver unparalleled retail solutions for the relatively untapped convenience store market.”
