Gross margin for the fourth quarter was 58%, compared to 55% in the fourth quarter of fiscal 2010. The increase primarily reflected increased sales mix of higher margin LifeVest business and improved pricing in the North American core defibrillator business.

Commenting on the year, Richard A. Packer, Chief Executive Officer of ZOLL, stated, “2011 was a very strong year for ZOLL. Our annual revenues exceeded $520 million for the first time, making us the clear leader in the resuscitation market. We were particularly happy to outperform our bottom-line. The key revenue drivers included a strengthening of our core defibrillator business along with continued growth in both our LifeVest and Temperature Management businesses.”

With respect to Q4, Mr. Packer commented, “With another strong quarter, our core North America defibrillator business now appears to be gaining traction. We were very excited to see strong double-digit defibrillator growth in both our core Hospital and EMS businesses. In fact, order growth exceeded shipment growth in both of these businesses. Core International shipments continued to be strong as we relieved some of our pent up backlog. We believe we have momentum worldwide across our core defibrillator business.”

Mr. Packer observed, “The LifeVest experienced another very successful quarter. We eagerly await the results of the CMS reimbursement review. We remain very confident that the data and widespread cardiology support will validate the original DMAC decision to cover the LifeVest during critical ICD waiting periods. We saw very positive written support in favor of maintaining current reimbursement from all major medical associations including the Heart Rhythm Society (HRS), the American College of Cardiology (ACC), the American Heart Association (AHA), the American Stroke Association (ASA) and the American Association of Heart Failure Nurses (AAHFN). These institutions recognize the critical importance of maintaining access to the only available life-saving cardiac arrest treatment during the high risk ICD waiting periods for this country’s senior citizens. Both the clinical data and the clinical support for this product continue to grow. Additionally, we believe the overwhelming positive response from the clinical community during the public comment period bodes well for future adoption of this therapy.”

Mr. Packer further added, “We were pleased by the excitement generated at the AHA meeting in Orlando this past week. At the Resuscitation Science Symposium (ReSS) and subsequent meetings, 27 clinical presentations relating to ZOLL products were made. Highlights included the publication of CIRC trial results and presentations on the LifeVest. These presentations clearly reinforce the effectiveness of each product.”

Mr. Packer concluded, “Looking forward we anticipate 17-19% revenue growth in 2012 with acceleration in our core business. We expect the LifeVest and Temperature Management businesses to again achieve very high growth rates in 2012. We also expect our rate of profitability to improve as our core business continues to grow and our business mix continues to get more favorable. We expect to continue progress towards our goal of getting our long-term operating profitability into the mid-teens.”
