April 26, 2006

MicroMaxx system sales rise to 46% of worldwide revenueUS direct sales force shows strong momentum with 45% revenue growth

BOTHELL, WA - April 26, 2006 - SonoSite, Inc. (Nasdaq:SONO), the world leader in hand-carried ultrasound, today reported financial results for the first quarter ended March 31, 2006.

Worldwide revenue in the first quarter of 2006 grew 9% to $36.9 million compared with $34.0 million in the first quarter of 2005. The first quarter of 2005 included over $3 million of enterprise project revenue from US and international government entities and impacts the comparison with 2006. Changes in the foreign currency rates decreased the revenue growth rate by approximately 3% in the first quarter.

Overall, US revenue grew 15% in the first quarter over the prior year with sales growing 45% from direct sales. As expected, the company's US enterprise sales which are primarily comprised of sales to governmental entities declined 57% in the first quarter of 2006 due to the high volume of project orders in the comparable quarter of the prior year. International revenue grew 3% over the prior year. The prior year's first quarter also included a large government order. Changes in foreign currency rates reduced the international growth rate by 5%. US revenue accounted for 49% of total revenue in the first quarter of 2006.

The company's 2006 financial results reflect adoption of FAS 123R, "Share-Based Payment", on January 1, 2006. For the first quarter of 2006, SonoSite reported a net loss of $363,000, or $0.02 per share, compared with net income of $725,000, or $0.05 per diluted share, in the prior year.

First quarter results in 2006 included $1.3 million of stock-based compensation, or $846,000 and $0.05 per share on an after-tax basis. Of this amount, the adoption of FAS 123R had an after-tax impact of $661,000, or $0.04 per share, and compensation from restricted stock grants had an after-tax impact of $185,000, or $0.01 per share. On a comparative after-tax basis, the first quarter of 2005 included $12,000 of stock-based compensation for restricted stock grants.

"We are highly encouraged by the performance and momentum in our US direct sales organization which turned in a 45% sales increase over last year's first quarter, reflecting the continuing success of the MicroMaxx system and improved execution," said Kevin M. Goodwin, SonoSite President and CEO. "As expected, enterprise sales were down in the quarter given the tough comparison of a year ago. This business is historically hard to predict and very variable."

Mr. Goodwin continued, "Internationally, we saw excellent growth in a number of our markets, although, overall performance was impacted by currency translation and results in Japan, which we expect will show improvement later this year. The year-over-year comparison was also difficult due to a large government order in our international business as well. We are seeing good evidence that Germany is on a positive track with the addition of experienced sales talent and the recently announced alliance with Siemens. The MicroMaxx system continues to enjoy strong worldwide acceptance and rose to account for 46% of the quarter's worldwide revenue."

Operating expenses grew 22% to $27.1 million in the first quarter of 2006 compared with the same period in 2005. Excluding stock-based compensation expense, operating expenses grew 16% in the quarter over the prior year to $25.8 million. The increase in operating expenses primarily resulted from investment in the company's international sales and marketing infrastructure and expansion of the US enterprise business unit and sales education initiatives.

Cash, cash equivalents and investments increased by $9.4 million to $80.2 million as of March 31, 2006.

Company Outlook for Second Quarter and 2006
Management continues to target a revenue growth rate of approximately 25% and expects full year revenue to be in a range of $180 - 187 million. Quarterly revenue is expected to vary following historical seasonal patterns. The company expects second quarter revenue to grow approximately 25% over the prior year's second quarter. Quarterly revenue is expected to grow sequentially in the remainder of the year with approximately one-third of the year's revenue occurring in the seasonally strong fourth quarter. Factors such as timing of large project orders from governmental or international entities cause variability in quarterly growth rate comparisons.

The company expects annual and quarterly gross margin to approximate 71%. Excluding stock-based compensation expense, operating expenses for the year are expected to approximate 59% to 60% of revenue and to vary following historical patterns. As of January 1, 2006, the company adopted FAS 123R, "Share-Based Payment", and estimates that stock-based compensation expense, including options, restricted stock grants and the employee stock purchase plan, will be approximately $9.0 million on a pre-tax basis in 2006, with an expense of approximately $2.5 million quarterly for the remainder of the year. Other income is expected to be approximately $2.4 for the year. The company expects its overall effective tax rate for 2006 to be approximately 33% to 35%.

For the year, the weighted average fully diluted common shares outstanding is expected to be approximately 17 million shares.
Executive Appointments in Marketing, Sales and Education Announced
SonoSite also announced that Edison (Ed) C. Russell, Senior Vice President, US Sales has decided to retire, effective June 30, 2006. Thomas J. Dugan, currently Senior Vice President, Marketing is being promoted to Senior Vice President, Global Marketing and US Sales and will assume Mr. Russell's responsibilities for the US sales organization. The company also announced the promotion of David R. Levesque, currently Director, Training and Education to Vice President, Worldwide Global Learning, responsible for sales and clinical training and customer education.

"Under Ed's leadership, the execution and performance of our US sales team has steadily improved,"
Mr. Goodwin said. "We appreciate his many contributions and wish him the best.

We believe that by consolidating our sales and marketing organization, our focus and effectiveness will further improve in our target markets."

"His promotion underscores the strategic importance we are placing on expanding customer education."

Non-GAAP Measures:
This release includes measures that are not in accordance with generally accepted accounting principles (non-GAAP). In the first quarter of 2006, the company adopted Financial Accounting Standards Board Statement No. 123R (SFAS 123R), which requires companies to recognize the compensation cost associated with stock-based awards in their financial statements. As a result, our financial statements for the first quarter of 2006 include stock-based compensation expense from options and employee stock purchase plan, but our financial results for the first quarter of 2005 do not include such stock-based compensation expense because periods prior to January 1, 2006 are not required to be restated. In addition to the stock-based compensation from options and employee stock purchase plan, we have stock-based compensation from grants of restricted stock units in the first quarter of 2006 and 2005. We have provided non-GAAP financial information that includes all stock-based compensation expense. We believe that it is useful to investors to understand how the expenses associated with stock-based compensation are reflected on our statements of operations. For our internal budgets, management uses financial statements that do not include stock-based compensation expense related to our stock-based awards. Management also uses the non-GAAP measures, in addition to the corresponding GAAP measures, in reviewing the financial results. The non-GAAP information should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP.
