Our results provide continued evidence of the cardiovascular surgery community's growing acceptance of the ATS Open Pivot(R) heart valve as a new `Standard of Care' for mechanical heart valve replacement. Sales in the United States grew to $1.8 million during the quarter and $5.1 million for the year. International sales grew to $3.9 million during the quarter and $13.3 million for the year." "During 2003, we took several steps to improve our future growth and profitability." Mr. Dale continued, "Most importantly, we established a global sales and marketing team comprised of some of the most experienced and successful cardiovascular surgery professionals in the industry. These people are perhaps the best example of our capacity and commitment to fulfill our mission to become a leader within cardiovascular surgery. We also strengthened our balance sheet by eliminating $28 million in long-term debt and commitments related to our carbon technology license, and significantly reduced our high-cost inventories paid for in prior years. Looking forward, we feel confident that ATS will be able to grow 2004 total revenue by at least 30% versus 2003. Regarding cash requirements, we believe current cash balances are adequate to fund current operations throughout 2004," concluded Mr. Dale. - 5 - CONFERENCE CALL TODAY ATS management will host a conference call and webcast today at 3:00 p.m. EST to discuss its fourth quarter and full year financial results, outlook for 2004 and current corporate developments.
