ZOLL Medical Corporation Announces Less Than Expected Quarterly Revenue and Earnings

Chelmsford, MA  Tuesday, April 06, 2004 – ZOLL Medical Corporation (Nasdaq: ZOLL), a manufacturer of non-invasive cardiac resuscitation devices which provide pacing and defibrillation, today announced that revenues for the second quarter ending April 4, 2004 would be approximately $50 - $51 million. This level of revenue would represent approximately 7-9% growth over the comparable year ago period. As a result of lower revenues, the Company expects earnings per share to fall substantially below the First Call consensus estimate of $0.35. The Company estimates that earnings per share will be in the range of $0.16 to $0.20 for the quarter.

A conference call will be conducted at 9:00a.m. on Tuesday, April 6, 2004 to discuss this matter in further detail.

Richard A. Packer, President and Chief Executive Officer, commented, “Business was generally soft across the board this quarter. Most significantly, order rates were lower than anticipated in the International market. International revenue was essentially unchanged over the second quarter of last year. Additionally, in the North American EMS market, orders were not as strong as anticipated.”

With respect to earnings in the second quarter, Mr. Packer said, “We have been ramping up expenses as we invest in stronger International distribution, greater North American sales coverage in both the professional market and the AED markets, and research & development. We believe these investments are required as we position ZOLL for additional growth. Obviously these investments have a large impact on our bottom line when revenues fall short. Since our quarter is back-loaded, the revenue shortfall was unexpected and did not allow us to adjust expenses to a material degree. Therefore, our earnings have taken a significant drop in spite of the modest increase in revenues compared to last year.” The Company expects to report final financial results and normal market information the week of April 19, 2004.

Mr. Packer continued, “Not all orders received were able to be shipped in the quarter. During the quarter we received two large orders from the U.S. Army as part of the Military PMI program. These orders approximated $7.2 million. However, at quarter end we still had approximately $4.0 million of military orders in backlog.”

Summarizing, Mr. Packer stated, “We are very disappointed with this result and our performance. We are working to take actions to strengthen our performance. Naturally, our outlook for the remainder of the year is cautious. We anticipate lower growth than originally envisioned. Currently we see revenue growth for this year in the 10-15% range compared to last year and earnings per share in the $1.15 – $1.25 range.”

“However, over the longer term I believe that we are taking the right steps to expand our product portfolio and distribution”, Mr. Packer said. “We expect our performance in the AED market to continue to improve and we look forward to improving market conditions in the U.S. EMS market. We must continue to move ahead in building International distribution. Our R&D spending remains high and we are confident that our product pipeline will be strong. New products such as the AutoPulse™ from Revivant and the Power Infuser® from our recent acquisition of Infusion Dynamics, will take advantage of the investments we are making in building distribution, and also offer significant upside potential as we look toward 2005 and beyond. We remain optimistic about our prospects for long term growth.”
