FOR IMMEDIATE RELEASE

ZOLL Medical Corporation Announces Record Annual Results

— Reports Record Fourth Quarter Revenue and Earnings —

        Chelmsford, MA, November 6, 2003 – ZOLL Medical Corporation (Nasdaq: ZOLL), a manufacturer of non-invasive cardiac resuscitation devices which provide pacing and defibrillation, today announced record annual revenues of $184,603,000, an increase of 23% as compared to annual revenues of $150,227,000 last year. Net income and earnings per diluted share also increased to record levels, posting a gain of 26% and 25%, respectively, to $12,850,000 or $1.40 per diluted share for the year as compared to $10,230,000 or $1.12 per diluted share for the comparable prior year period.

        Annual sales in the North American market grew by 18% over 2002. Revenues reached $138.5 million as compared to $117.0 million for the prior year. Sales to the North American hospital market increased 25% to $63.6 million, as compared to $50.7 million last year. Sales to the North American pre-hospital market grew 18% to $55.4 million as compared to $47.0 million for the prior year. International sales increased 39% to $46.1 million as compared to $33.2 million for the prior year. Annual sales of the new AED Plus product totaled $18.8 million as compared to $6.6 million in the prior year.

         Fourth quarter 2003 revenues increased 6% over 2002 to $50,206,000. As previously disclosed, in the fourth quarter of 2002 both revenues and earnings were unusually high due to approximately $2.5 million of shipments that were shipped in the fourth quarter of 2002 instead of the third quarter of 2002 due to a production problem experienced in the third quarter of 2002. Net income for the fourth quarter of 2003 increased 7% to $4,867,000 and earnings per diluted share increased 6% to $0.53 as compared to $4,540,000 or $0.50 for the comparable prior year quarter, respectively.

         Fourth quarter sales to the North American market grew to $39.4 million, an increase of 9% as compared to the fourth quarter of 2002. North American hospital revenues increased 25% to $18.8 million as compared to the fourth quarter of last year. Sales to the North American pre-hospital and International markets decreased by 3% and 4% to $15.8 million and $10.8 million, respectively. AED sales were $5.3 million in the quarter.

    Richard A. Packer, President and Chief Executive Officer of ZOLL commented on the results, “We are proud to have completed another strong year at ZOLL. The fourth quarter was very strong even though the prior year comparatives may not show it due to last year’s unusually high shipments. We were especially pleased that our fourth quarter gross margins came in higher than expected, due to both a higher average selling price and improved mix, thereby allowing us to achieve our bottom line growth objectives while at the same time increasing our backlog heading into the first quarter.”

    With respect to the North American Hospital market, Mr. Packer stated, “We were pleased to receive an additional order of approximately $7 million from the United States Military for our M Series CCT defibrillator. This order reflects the confidence military customers have in the durability and technological advantages of our M Series product line and is a follow-on to orders of more than $10 million received earlier in 2003. However, even without this order, most of which remains in our backlog, we had a strong quarter in the North American hospital market. We are hopeful that this is a sign that the hospital market is poised to grow once again.”

    Commenting further, Mr. Packer observed, “We performed well in the quarter in both the US EMS and International markets, although again, each had unusually high comparisons from last year and we increased our backlog. In the AED market, we came up a little short of our $20 million goal for first year shipments, which I attribute to the loss of momentum we experienced in Q3. However, we were pleased to see a resumption of strong sequential quarterly growth. We have taken a number of actions to strengthen our performance in this market. We will continue to add significant resources to our sales efforts in the AED market to help us achieve continued growth in our market share.”

     Mr. Packer concluded, “Our outlook for the company remains bright and unchanged. We continue to see a strong year in 2004 with both sales and earnings growing approximately 20%. We believe that the North American market is strengthening, that we will be successful in building our AED business, and that we have further room to grow internationally. During 2004, we will stay the course of strengthening our distribution channels and investing in our infrastructure to position ourselves for the future.”
