2007 Revenue Tops $205 Million New Products Account for Over 30% of Fourth Quarter Revenue BOTHELL, WA, January 7, 2008 - Sonosite, Inc. (Nasdaq:SONO), the world leader in point-of-care, hand-carried ultrasound, today provided preliminary revenue results for the fourth quarter ended December 31, 2007. The company said that fourth quarter revenue grew approximately 20% to $65 million compared to the prior year's fourth quarter. For the year, worldwide revenue is estimated to have increased by 20% to over $205 million. Sonosite President and CEO Kevin M. Goodwin said that the new M-Turbo„¢ and S Series„¢ products, which the company began shipping in December, accounted for over 30% of the quarter€™s revenue.

"Market response and uptake worldwide was stronger than we expected in the first quarter of our product launch," Mr. Goodwin said. "This is a particularly encouraging given that we essentially had only 40 selling days with our new products in the field in the fourth quarter." The company unleashed its largest ever roll-out of five new products at major medical meetings during the fourth quarter of 2007.

As previously announced, Mr. Goodwin will be presenting at the Annual JPMorgan Healthcare Conference on January 7, 2008 at 9:00 am Pacific Time in San Francisco.
