Company Reports Revenue Growth of 23% and EPS of $0.07 Conference Call Today at 1:30 pm Pacific/4:30 pm Eastern BOTHELL, WA - April 28, 2008 - Sonosite, Inc. (NasdaqGS:SONO), the world leader and specialist in hand-carried ultrasound for the point-of-care, today reported record financial results for the first quarter ended March 31, 2008. Worldwide revenue in the first quarter of 2008 grew 23% to $52.5 million compared with the first quarter of 2007. Changes in foreign currency rates increased worldwide revenue by approximately 4%. Compared to the first quarter of 2007, international revenue grew 32% and US revenue grew 12%.

In the US, hospital revenue grew 16% and office revenue grew 33%. The overall US growth rate was offset by an expected decline in US enterprise revenue of 17%. For the first quarter of 2008, Sonosite reported net income of $1.2 million, or $0.07 per diluted share, compared with a net loss of $563,000 or $0.03 per share for the first quarter in 2007. Net income in the quarter included a one-time, pre-tax charge of $675,000 for integration of the former MarketBridge physician office channel and the elimination of overhead within the company's marketing, general and administrative structure. Cash flow from operations was $7.3 million in the quarter. "The year is off to an excellent start and we are on track to achieve our growth and profitability objectives for 2008," said Kevin M. Goodwin, Sonosite President and CEO.

"We saw good momentum across our major markets driven by strong reception to our new products which accounted for over 40% of the quarter's revenue." "The international group continued their blistering pace and marked the sixth consecutive quarter of growth exceeding 20%," Mr. Goodwin said. "In the US, we saw good performance in the hospital and office sectors immediately after integrating these channels inside the company during the first quarter. We are looking forward to a year of continued progress in the US."

In the first quarter, gross margin grew to 72% compared with 70% in the first quarter of 2007 and reflected the positive impact of the company's new fourth generation products, the M-Turbo„¢ and S Series„¢ products introduced in October 2007, as well as the favorable impact of foreign currency rates. Operating expenses grew 10% to $35.4 million (including the previously mentioned one-time charge) compared with the same period in 2007. Changes in foreign currency rates and the one-time charge increased operating expenses by 4%. As of March 31, 2008, cash, cash equivalents and investments were $315.9 million.

Company Outlook
Sonosite management updated its 2008 financial objectives. Management's "base plan" is to achieve revenue growth of at least 15%, gross margins of approximately 70% and operating margins of 9 - 10%. Due to lower market interest rates, the company expects interest income to be offset by interest expense in 2008. The company expects to have a tax rate of approximately 39% for the year, virtually all of which is a non-cash item. Income taxes are largely a non-cash expense due to unused net operating loss carryforwards. The company reiterated its target to achieve a 15% operating margin in 2009.
