ZOLL Medical Corporation Announces First Quarter Results

~ Record First Quarter Revenue and Earnings ~

CHELMSFORD, Mass.--(BUSINESS WIRE)--January 27, 2011--ZOLL Medical Corporation (Nasdaq GS: ZOLL), a manufacturer of resuscitation devices and related software solutions, today announced that revenues for the first quarter of fiscal 2011 increased 8% to $113.2 million, compared to revenues in the first quarter of last year of $105.2 million. As previously disclosed, the first quarter of fiscal 2010 contained an extra week, contributing both incremental revenue and expenses of approximately $2 million. Net income increased 69% to $3.9 million for the quarter, compared to $2.3 million in the prior year. Diluted earnings per share were $0.18, compared to $0.11 in the prior year. Backlog at the end of the first quarter was approximately $13 million, as compared to approximately $14 million at the end of fiscal 2010 and to $17 million at the end of Q1 2010.

We have revised the presentation of our customer classes and have now segregated the LifeVest® revenues into a new LifeVest customer class. These revenues were historically presented in the North American pre-hospital and International customer classes. Additionally, we removed the North American-Other customer class, which consisted of defibrillator electrodes, and assigned these revenues to their respective North American hospital or North American pre-hospital customer class.

Sales to the North American hospital market increased 2% to $30.6 million, compared to $30.0 million for the same period last year. North American hospital revenues included U.S. Military/Big Government sales of $8.6 million in the first quarter of fiscal 2011, compared to $6.5 million for the same period in the prior year. Excluding this military business, core North American hospital sales decreased 6%. Sales to the North American pre-hospital market decreased 10% to $27.4 million, compared to $30.6 million in the prior year. International revenues increased by 10% to $32.8 million, compared to $29.8 million last year. LifeVest revenues increased 50% to $22.3 million.

From a product perspective, total AutoPulse^® sales increased 25% to $4.8 million, compared to $3.9 million in the first quarter of last year. The AutoPulse is marketed and sold to hospitals and EMS agencies worldwide and, therefore, AutoPulse sales are included in our North American Hospital, North American pre-hospital and International customer classes noted above.

Total Temperature Management sales increased 28% to $5.9 million, compared to $4.6 million in the same period last year. The Temperature Management products are marketed and sold to hospitals both domestically and internationally and are, therefore, included in the North American hospital and International customer classes.

Gross margin for the first quarter was 54%, compared to 53% in the first quarter of fiscal 2010. The increase primarily reflected improved pricing in the North American core defibrillator business and an increased mix of LifeVest revenue.

The tax rate for the quarter of approximately 31% was lower than expected, reflecting discrete credit for retroactive passage of the R&D tax credit. We expect our tax rate for the full year to approximate 35%.

Richard A. Packer, Chief Executive Officer of ZOLL, commented, “Overall, the markets for our products behaved much like we anticipated. In the core hospital business, although shipments were down modestly, our orders were up in line with our expectations. This disparity reflects the timing of shipments from our backlog, so we remain confident we will grow in the North American hospital market this year. Conversely, our North American pre-hospital business results have experienced softness as we anticipated, and we see this continuing throughout the year.”

Mr. Packer noted, “Our LifeVest revenue continues to perform well. Adjusting for the extra week in the prior year, LifeVest revenues increased in line with our 60% goal. Temperature Management also experienced solid growth as we gain traction with our transition to a direct sales force in Germany. Lastly, AutoPulse sales continued to improve with strong results from our International team.”

Mr. Packer concluded, “We were pleased with our overall results for the quarter, and did a little better at the bottom line with the benefit of the R&D tax credit. Moving through the year, we expect to continue to increase our overall level of profitability as we gain leverage. We believe we are on track for the year and our outlook for 2011 is unchanged.”

ZOLL will host a conference call on Thursday, January 27, 2011 at 5:00 p.m. EST to discuss its first quarter financial results. This conference call will be accessible on the Company’s home page at www.zoll.com. Recorded replays of this conference call will be available on the web page beginning later that day.
