BOTHELL, WA – January 5, 2010 – Sonosite, Inc. (Nasdaq:SONO), the world leader and specialist in hand-carried ultrasound for the point-of-care, today provided preliminary revenue results for the fourth quarter and year ended December 31, 2009. Overall 2009 revenue was approximately $69 million in the fourth quarter and $227 million for the year. Overall revenue included $4 million for the fourth quarter and $7 million for the year from the recently acquired CardioDynamics International Corporation (CDIC). Excluding CDIC, revenue was down 7% in the fourth quarter and down 10% for the year compared to the prior year.

For the quarter, a decrease in military orders caused a 6% revenue decline. Changes in foreign currency rates increased revenue in the fourth quarter by 4% but decreased revenue by 2% for the year. “Exiting 2009, we were encouraged by an uptick in momentum during the fourth quarter,” said Kevin Goodwin, Sonosite President and CEO. “On a constant currency basis, international revenue was level in the fourth quarter and grew 1% for the year. Our US Direct business was down compared to the prior year but continued to grow sequentially. Strong US bookings at the year end and a positive outlook by our sales force have provided some renewed optimism heading into 2010.” The revenue estimates are preliminary. Sonosite plans to report complete fourth quarter and 2009 financial results on February 11, 2010 after the close of the financial markets.
