SonoSite Previews Preliminary First Quarter Revenue Results

SonoSite, Inc. (Nasdaq:SONO), the world leader and specialist in hand-carried and point-of-care ultrasound, today provided preliminary revenue results for the first quarter ended March 31, 2009.

The company said worldwide revenue decreased by 1% - 2% in Q1 2009 compared to Q1 2008. On a constant currency basis, worldwide revenues grew 6% - 7% in the quarter, indicating a currency headwind of approximately 8%.

US revenues grew approximately 4% year over year. Continued slowing of US hospital capital spending drove a mid-teen percentage decline in SonoSite’s US hospital revenues. This was offset by excellent growth in the company’s US enterprise channel. International revenues decreased approximately 6% in the quarter, driven by the impact of a weaker dollar. On a constant currency basis the International sector was up approximately 8% in Q1 2009 on a year over year basis.

These revenue estimates are preliminary. The company will report full financial results for the first quarter on April 27, 2009 after the close of market.
