VOLCANO CORPORATION ANNOUNCES PRELIMINARY RECORD REVENUES

FOR FOURTH QUARTER 2010 AND FULL YEAR 2010

TOTAL 2010 REVENUES EXPECTED TO EXCEED GUIDANCE

(SAN DIEGO, CA), January 10, 2011—Volcano Corporation (NASDAQ: VOLC), a leading developer and manufacturer of precision intravascular diagnosis and therapy guidance tools designed to enhance the treatment of coronary and peripheral vascular disease, said today that it expects total revenues for the fourth quarter of 2010 will be approximately $81.0 million, bringing expected full year 2010 revenues to approximately $294.0 million.

The company’s revenue expectations for fiscal 2010 compare with prior guidance for revenues of $286.0-$290.0 million and reflect year-over-year revenue growth of approximately 29 percent.

The expectations for revenues in the fourth quarter of 2010 reflect an increase of approximately 14 percent versus the fourth quarter a year ago. Revenues for the fourth quarter of 2010 will be negatively impacted by approximately $3.0 million related to the Fukuda transition in Japan completed on December 1, 2010. Revenues in the fourth quarter of 2009 were favorably impacted by the first full quarter of a direct sales program in Japan resulting from the company’s termination of a distribution agreement with its largest distributor in the market.

“As has been the case for the past number of quarters, our performance in the fourth quarter of 2010 was driven by continued adoption of our multi-modality platform and increased market share and utilization for our IVUS (Intravascular Ultrasound) and FM (Functional Measurement) disposables,” said Scott Huennekens, president and chief executive officer. “We continued to realize growth in our key geographies, including Japan where we are now addressing 95 percent of the market with our direct selling program,” he added.

The company said it was providing the updated revenue guidance for 2010 in advance of meetings with the investment community and its presentation at the 29^th Annual J.P. Morgan Healthcare Conference. The company’s presentation will occur at 9 a.m., Pacific Standard Time (12 p.m., Eastern Standard Time), Tuesday, January 11. A webcast of the presentation will be available through the conference website at http://jpmorgan.metameetings.com/webcasts/healthcare11/directlink?ticker=VOLC and via the company’s website at www.volcanocorp.com.

The company’s fourth quarter and full year 2010 financial results and guidance for fiscal 2011 will be provided in a press release, as well as a conference call and webcast open to all interested parties, in late February. Details for the earnings press release date, conference call and webcast will be provided in a subsequent press release.
