Revenues The following table summarizes the Company's revenues by product line for the first quarters in 2003 and 2002 (in thousands): Product Lines 2003 2002 % 1st Qtr 1st Qtr Change Medical Technology: Medical Batteries: ICDs $10,760 $6,506 +65% Pacemakers 6,037 5,529 +9% Other Devices 806 1,002 -20% Total Medical Batteries 17,603 13,037 +35% Capacitors 7,148 5,749 +24% Components 23,277 11,527 +102% Total Medical Technology 48,028 30,313 +58% Commercial Power Sources 6,829 5,990 +14% Total Revenues $54,857 $36,303 +51% "I am extremely pleased with our results for the first quarter. The cardiac rhythm management (CRM) market growth is robust and its impact can be seen across many of our product lines," stated Edward Voboril, the Company's Chairman, President and Chief Executive Officer. "With the CRM market now comprising most our overall sales mix, we are very well positioned in this exciting market segment," Voboril continued. "In our medical power product area, our high voltage defibrillator battery revenues reached a record high in the quarter. We are seeing strong demand for our high voltage batteries used in both implantable cardioverter defibrillators (ICD) and cardiac resynchronization therapy devices (CRT). In terms of pacemaker battery revenues, as we have previously discussed, revenues throughout most of the first half of 2002 were impacted by inventory reductions by certain customers. The growth in the first quarter of this year was a result of increased sales to these customers. Our capacitor revenues in the quarter remained strong. While the revenues represent sales to a single customer, we expect sales to the second and third customers to commence in the second half of the year," Voboril commented. "Turning to the medical component product area, revenues doubled from last year. This was due in part to the acquisition of Globe Tool completed in July 2002. Aside from the Globe enclosure products, the organic growth of filtered feedthroughs was in excess of 60% over the prior year. This strong growth reflects introductions of ICDs, Pacemakers and CRT devices by our customers, which utilize our proprietary electro-magnetic filtering technology," stated Voboril. "In our non-medical, commercial battery segment, the revenue growth reflects demand from our customers in the oil and gas exploration market. As we head into the heart of the oil-drilling season over the next two quarters, our outlook for the remainder of the year remains cautiously optimistic. The uncertainties overseas have created some concern with our customers and, therefore, it is too soon to determine how long this level of increased demand will continue," Voboril added. Profit & Loss Summary The following table summarizes selected information derived from the profit & loss ("P&L") statements for the 1st quarters for 2003 and 2002 (in thousands): Selected P & L Amounts 2003 2002 1st Qtr 1st Qtr Gross Profit $22,813 $15,952 Gross Margin 41.6% 43.9% SG&A Expenses 7,691 5,657 SG&A Expense as% of Revenue 14.0% 15.6% RD&E Expenses, net 4,560 3,653 RD&E Expenses, net as % of Revenues 8.3% 10.1% Operating Income $9,747 $5,756 Operating Margin 17.8% 15.9% "The decrease in gross margin in the quarter compared to last year is primarily due to the lower margin Globe enclosure products. In addition to the product mix, we incurred integration-related costs in the first quarter for the ongoing consolidation of our commercial battery facilities in Massachusetts. The consolidation is on track in terms of planned costs and for completion by the end of the second quarter," Voboril commented. "Furthermore, we incurred costs in the quarter pertaining to our enterprise-wide Six Sigma lean manufacturing initiative. The completion of the commercial plant consolidation, coupled with the ongoing lean manufacturing initiatives, should allow us to see gross margin improvement in the second half of this year," Voboril stated. "The improvement in the operating margin reflects the impact of both the increased sales and the leverage of existing SG&A infrastructure. We will continue to invest in support of the growth of the business, while at the same time delivering on our expectations," Voboril concluded. Conference Call Edward F. Voboril and Lawrence P.
