Conference call today at 1:30 PT/4:30ET BOTHELL, WA - October 30, 2006 - Sonosite, Inc. (Nasdaq: SONO), the world leader in hand-carried ultrasound, today announced financial results for the third quarter and nine months ended September 30, 2006. As the company previously disclosed in its news release issued on October 16, 2006, worldwide revenue in the third quarter of 2006 increased 16% to $40.3 million compared with $34.8 million in the third quarter of 2005. During the third quarter, total US revenue grew 15% to $23.4 million and international revenue grew 18% to $16.9 million compared with the prior year quarter. For the nine months of 2006, worldwide revenue grew 14% to $116.7 million compared with $102.3 million for the nine months of the prior year.

US revenue accounted for 58% of third quarter revenue and 53% of year-to-date revenue in 2006. For the third quarter of 2006, Sonosite reported net income of $475,000 or $0.03 per diluted share compared with net income of $1.4 million or $0.09 per diluted share in the third quarter of 2005. For the nine months of 2006, Sonosite reported net income of $1.4 million or $0.08 per diluted share compared with net income of $119,000 or $0.01 per diluted share in the comparable period of the prior year.

"As we communicated earlier this month, we saw strong performance in a number of key US sales territories and international markets during the third quarter, however the breadth of performance was not what we expected as we implemented new sales initiatives in the US and internationally," said Kevin M. Goodwin, Sonosite President and CEO. "With the integration of a new sales channel partner to address the physician office market we have substantially increased our US sales capacity to approximately 63 sales consultants.

As we enter the year's seasonally strong fourth quarter we have our core direct sales reps now focused on the hospital point-of-care markets plus 18 new physician office reps. We are encouraged by the market activity we are seeing, the growing pipeline and the interest levels we are seeing at the fall trade shows. The MicroMaxx system continues to be a strong performer. Hospital sales are up over 30% year-to-date. We expect to see the US growth rate regain momentum as we fully execute on this strategy." "Internationally, a number of our subsidiaries showed excellent growth," added Mr. Goodwin. "With our new distribution partners in Germany and Japan and the strengthening of our organisations in China and India, we look for accelerating growth as we move into 2007."

In the third quarter of 2006, net income included a total of $1.5 million of stock-based compensation expense on an after tax basis and was comprised of $815,000 resulting from the adoption of FAS123R in January 2006 related to stock options and the employee stock purchase plan and $663,000 for the issuance of restricted stock units. Excluding all stock-based compensation, net income on a non-GAAP basis was $2.0 million in the third quarter of 2006 compared with $1.5 million in the third quarter of 2005.

Net income in the third quarter of 2005 included stock compensation expense on an after tax basis of $76,000 from the issuance of restricted stock units. For the nine months of 2006, stock-based compensation expense on an after tax basis was $3.7 million with $2.3 million resulting from the implementation of FAS123R and $1.4 million for the issuance of restricted stock units. Excluding all stock-based compensation, net income on a non-GAAP basis for the nine months of 2006 was $5.1 million compared with $229,000 in the comparative period of 2005. Net income for the nine months of 2005 included stock compensation expense on an after tax basis of $110,000, from the issuance of restricted stock units. Gross margin in the third quarter rose to 71.0% compared with 70.4% in the third quarter of 2005 primarily due to improved product mix. For the nine months of 2006, gross margin increased to 71.3% compared with 69.9% for the prior year nine months. Excluding stock-based compensation, operating expenses grew 21% during the third quarter of 2006 to $26.9 million compared with $22.3 million in the third quarter of 2005.

Operating expenses were higher due to continued investment in research and development, expanded clinical education and training programmes, continued expansion of operations in Japan, Canada, Australia and growth in the company's European subsidiaries. Including stock-based compensation expense, operating expenses grew 30% to $29.2 million compared with $22.4 million in the third quarter of 2005, and 19% in the nine months of 2006 to $84.2 million. As of September 30, 2006, cash, cash equivalents and investments totaled $86.0 million. For the nine months of 2006, cash, cash equivalents and investments grew by $15.2 million and inventories by $4.0 million due to an increase in finished goods to support higher planned sales levels for the seasonally strong fourth quarter and an increase in demo inventory to support the previously mentioned clinical education initiatives and international expansion.

The company also announced that Bradley G. Garrett, Senior Vice President and Chief Operating Officer, has elected to retire at the end of 2006. "We thank Brad for his many important contributions to the company's success since he joined Sonosite in 2000 and wish him all the best in his future endeavours," Mr. Goodwin said. "Brad has built a highly capable and strong operations and R&D organisation that will continue to drive our future growth. Brad's responsibilities will be undertaken by two respected and accomplished Sonosite executives. Jim Gilmore, Vice President, Engineering will oversee advanced development and all engineering functions and John Lowell, Vice President, Operations will oversee manufacturing and supply chain activities. Both Jim and John will become members of the Executive Committee and report directly to me," Mr. Goodwin added.

Company Outlook for 2006 and Preliminary Guidance for 2007
The company reiterated the guidance it provided in the previously referenced mid-October news release. For 2006, the company expects revenue growth of approximately 15% over that of 2005. GAAP pre-tax income is expected to be in a range of $8-9 million which includes stock-based compensation expense of approximately $8.3 million.
Excluding stock-based compensation, pre-tax income is expected to double over the prior year. "In looking at 2007, we are targeting full year revenue growth of at least 15-18% over that of 2006 and expect that quarterly revenue will follow their historical seasonal patterns," Mr. Goodwin said. "We are adopting a more conservative stance to our full year revenue projections to give time for our US and international initiatives to fully unfold. We continue to be positive on our outlook for the strong growth potential for the hand-carried market sector and our ability to maintain our leadership position. As we mentioned in our earlier October release, we plan to continue to expand our sales capacity in both US and international markets to fully caliptalise on this potential and to increase research and development investment aimed at delivering exciting new disruptive products in 2007 and beyond. It continues to be our goal to deliver solid increases in operating and pre-tax income in 2007," Mr. Goodwin concluded. The company plans to provide annual objectives in early 2007 after finalising its budget process.

Non-GAAP Measures
This release includes measures that are not in accordance with generally accepted accounting principles (non-GAAP). Effective as of the beginning of 2006, the company adopted Financial Accounting Standards Board Statement No. 123R, which requires companies to recognise the compensation cost based on the fair value of stock-based awards in their financial statements. As a result, financial results for 2006 include stock-based compensation expense from options, an employee stock purchase plan and restricted stock units, however the financial results for 2005 do not include such stock-based compensation expense from options or the employee stock purchase plan because periods prior to January 1, 2006 are not required to be restated. We have provided non-GAAP financial information that includes all stock-based compensation expense; as well, we have provided a non-GAAP measure of adjusted net income excluding all stock-based compensation.

We believe that it is useful to investors to understand how the expenses associated with stock-based compensation are reflected in our statements of operations. We include expense related to restricted stock units when excluding all stock-based compensation expense, since restricted stock grants were adopted as incentives in anticipation of the adoption of FAS 123R. For internal budgets, management uses financial statements that do not include stock-based compensation expense related to 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.
