Conference Call Today at 1:30 pm Pacific/ 4:30 pm Eastern BOTHELL, WA - October 29, 2007 - Sonosite, Inc. (Nasdaq:SONO), the world leader in hand-carried ultrasound, today reported financial results for the third quarter and nine months ended September 30, 2007. Worldwide revenue in the third quarter of 2007 grew 24% to $50.0 million compared with $40.3 million in the third quarter of 2006. For the nine months of 2007, worldwide revenue grew 20% to $140.2 million compared with $116.7 million for the nine months of 2006.

Changes in foreign currency rates increased the revenue growth rate by approximately 2 percentage points for both the quarter and the nine months. For the third quarter of 2007, Sonosite reported net income of $1.5 million or $0.09 per share, compared with net income of $475,000 or $0.03 per share in the third quarter of 2006. For the nine months of 2007, Sonosite reported net income of $2.6 million or $0.15 per share, compared with net income of $1.4 million or $0.08 per share in the nine months of 2006. "US revenue grew 21% and international revenue was up 28% in the quarter demonstrating continued progress," said Kevin M. Goodwin, Sonosite President and CEO.

"Improved performance and execution was broad based across our major markets and reflected increasing market share and growing momentum in our business." "During October we began to show the results of our increased R&D investment with the introduction of five new products that bring revolutionary performance and design to physicians at the point-of-care," Mr. Goodwin continued. "The M-Turbo„¢ system is the most powerful and versatile hand-carried ultrasound product on the market. Our new S Series„¢ visualization tools represent a totally new approach to ultrasound design with a product line that delivers the image quality equal to the powerful M-Turbo system, yet customized to the specific needs of emergency medicine physicians, anesthesiologists, intensivists and interventional radiologists.

Physicians have applauded the M-Turbo and S Series products for their breakthrough image quality and enhanced capabilities while not compromising on important attributes such as durability, reliability and speed-of-use. We plan to begin shipping these new products in the fourth quarter and expect that they will have a significant impact on our growth as we move into 2008 and beyond." In the third quarter, gross margin was 69.4% compared with 71.0% in the third quarter of 2006, and 69.5 % in the nine months of 2007 compared to 71.3 % in the same period of 2006. The rate decrease reflected a decline in international gross margins due to lower margin sales to distributors. Overall, US revenue accounted for 57% of total revenue in the quarter and 51% for the nine months as compared with 58% and 53% respectively in the prior year. Operating expenses grew 20% in total to $35.1 million in the quarter and 17% to $98.5 million in the nine months as compared with the same periods in 2006 and primarily reflected increased product development invested and higher legal expenses.

Compared to the prior year, R&D investment increased 30% for the quarter and 40% for the nine months reflecting investment in new product development. General and administrative expenses increased 58% for the quarter over the prior year€™s third quarter and 25% for the nine months due to increased legal costs for patent litigation. Sales and marketing expenses grew 10% for the quarter and 10% for the nine months compared to the prior year.

Despite the higher legal expenses, sales, general and administrative (SG&A) expenses decreased as a percentage of revenue to 56% for the third quarter compared with 59% in the year ago quarter and to 56% of revenue from 60% for the nine month comparable period of 2006. Changes in the foreign currency rates increased the expense growth rate by approximately 2 percentage points for both the quarter and the nine months. Other income in the third quarter was $2.5 million compared with $1.1 million in the third quarter of 2006 primarily due to foreign currency exchange gains resulting from a weaker dollar. As of September 30, 2007, cash and investments totaled $309 million. Days sales outstanding increased by four days from the second quarter due to increased international sales. Inventories increased by $3.0 million sequentially as production increased to meet second half demand and to support our recently launched new product platforms.

Company Updates Outlook for Remainder of 2007 and Previews 2008
The company updated its revenue guidance for 2007 and expects revenue growth of approximately 18% over the prior year. With a historically higher mix of US revenue and the expiration of the royalty to Sonosite€™s former parent, gross margin is expected to increase in the fourth quarter and to approximate 70% for the year. The company expects total operating expenses to approximate 67 - 68% of revenue for the year and includes expected higher patent litigation costs. Other income is expected to be approximately $6.0 million reflecting the increase due to foreign exchange gains resulting from the weaker dollar. The company still expects its tax rate to be approximately 36% for the year and diluted shares outstanding of approximately 17.2 million. For 2008, Sonosite is targeting revenue growth of at least 15%, gross margin of 70% and operating margins of approximately 7- 8 % which includes expected legal expenses for two patent litigation lawsuits scheduled to go to trial in the second half of 2008.
