Sunshine Heart Announces 3Q12 Financial Results

Key Regulatory and Financing Milestones Achieved

Eden Prairie, MN and Sydney, Australia: November 8, 2012: Sunshine Heart, Inc. (NASDAQ: SSH; ASX: SHC) today announced financial results for the third quarter and nine months ended September 30, 2012.

Third Quarter Milestones:

·                  CE Mark obtained for C-Pulse® Heart Assist System

·                  Public stock offering totaling $20.8 million

·                  Conditional IDE approval for U.S. FDA pivotal trial

·                  Positive efficacy trends reported in 12-month extended follow-up of feasibility study patients

·                  Seasoned U.S.-based chairman appointed to Board of Directors

Third Quarter Financial Highlights:

·                  SG&A expense totaled $1.5 million in the third quarter and $5.0 million year-to-date 2012 compared to $1.4 million and $3.3 million in 2011, respectively

·                  R&D expense totaled $1.8 million in the third quarter and $5.8 million year-to-date 2012 compared to $3.3 million and $7.9 million in 2011, respectively

·                  $17.4 million cash balance at September 30, 2012, up from $6.6 million at December 31, 2011

“Our third quarter was truly transformational,” commented Dave Rosa, Sunshine Heart’s CEO. “I am exceptionally proud of our accomplishments, as we achieved significant regulatory milestones in both the EU and the U.S., and successfully completed our initial U.S. public offering.  This financing enables the initiation of our U.S. FDA pivotal trial as well as our European post-market trial.  Together, these trials provide the opportunity to gather safety and efficacy patient data on our C-Pulse System as we continue our progress toward commercialization of the device in the U.S. and Europe.  We continue to be excited about the potential benefit our device may provide to patients and the ultimate market potential in front of us.  Our fourth quarter will be focused on securing unconditional IDE approval for our U.S. FDA pivotal trial and initiating sites in Europe,” concluded Rosa.

Operating expenses in the third quarter 2012 totaled $3.3 million, compared to $4.7 million in the third quarter of last year. The decrease was attributable to reduced spending on clinical trials and research and development projects during the period as a result of the timing of certain development activities and clinical trial expenses, partially offset by increased SG&A related to infrastructure development.

Operating expenses totaled $10.8 million in the first nine months 2012 compared to $11.2 million in the prior year’s period. The decrease resulted primarily from reduced spending on clinical trials and research and development projects during the period as a result of the timing of certain development activities and clinical trial expenses, partially offset by increased SG&A related to infrastructure development, increased legal, accounting and regulatory expenses associated with the Company’s listing on NASDAQ in February 2012 and increased non-cash compensation expense.  The Company’s year-to-date results reflect a $730,000 research and development tax credit refund by the Company’s Australian subsidiary related to eligible expenses incurred for the twelve-month tax period ended June 30, 2011, which was received and recognized in the second quarter of 2012.

Net loss in the third quarter and year-to-date 2012 was $3.3 million and $10.0 million, compared to losses of $4.7 million and $11.0 million in 2011, respectively.  Current year results are consistent with management’s expectations.

The Company ended the third quarter 2012 with a cash balance of $17.4 million compared to $6.6 million at December 31, 2011. Cash used in operating activities was $9.7 million in each the first nine months of 2012 and 2011.

Upcoming milestones:

·                  Announcement of EU site selection for post-marketing trial for the C-Pulse System expected to commence in the fourth quarter of 2012

·                  Unconditional IDE approval from the FDA expected in the fourth quarter of 2012

·                  Initiation of pivotal trial planned for the fourth quarter of 2012

About the C-Pulse® Heart Assist System

The C-Pulse Heart Assist System, or C-Pulse System, an investigational device in the United States, Canada and countries that do not recognize the CE Mark approval, utilizes the scientific principles of intra-aortic balloon counter-pulsation applied in an extra-aortic approach to assist the left ventricle by reducing the workload required to pump blood throughout the body, while increasing blood flow to the coronary arteries.  Operating outside the patient’s bloodstream, the extra-aortic approach of the C-Pulse technology offers greater flexibility, allowing patients to safely disconnect to have intervals of freedom to perform certain activities such as showering.  The C-Pulse System may help maintain the patient’s current condition and, in some cases, reverse the heart failure process, thereby potentially preventing the need for later stage heart failure therapies, such as left ventricular assist devices (LVADs), artificial hearts or transplants.

Caution: Investigational device, limited by Federal (or United States) Law to Investigational use.
