Exhibit 99(a) IMMEDIATE RELEASE MARCH 9, 2004 CONTACTS: BRENT LARSON, JONATHAN FASSBERG, VP FINANCE & CFO THE TROUT GROUP 614 793 7500 212 437 9007 - ------------------------------------------------------------------------------- NEOPROBE ANNOUNCES 2003 FISCAL YEAR RESULTS Annual Revenues Increase 32%, Net Loss Decreases 39% DUBLIN, OHIO - March 9, 2004 -- Neoprobe Corporation (OTCBB: NEOP) today announced financial results for the fourth quarter of 2003 and for the full year that ended December 31, 2003. Results for the fourth quarter and for the full year of 2003 include the consolidated operations of Neoprobe Corporation and its wholly owned subsidiary, Cardiosonix Ltd. For the fourth quarter of 2003, Neoprobe had a net loss of $582,000 or $0.01 per share. For fiscal year 2003, Neoprobe incurred a loss of $1.8 million or $0.04 per share. The net loss decreased by 39% compared to the prior year. For the year 2003, Neoprobe reported revenues of $6.5 million compared to $4.9 million in the prior year. Total revenue increased 32% on a year-to-year basis. Revenues for 2002 were adversely affected by an inventory overstock situation at Neoprobe's primary gamma products distributor. For the fourth quarter of 2003, Neoprobe reported revenues of $1.9 million compared to $1.7 million for the fourth quarter of 2002. Revenues for 2003 exhibited a recovery to a level we expect to be sustainable during 2004. Annual gross profit was 52% for both 2002 and 2003. The operating results for 2003 reflect the continued investment in the development and commercialization of our Quantix(R) blood flow measurement technology. However, Neoprobe's research and development costs for 2003 decreased to $1.9 million compared to $2.3 million in 2002 due primarily to headcount reductions made in our gamma development team at the end of 2002 and the transition from development to clinical evaluation and commercialization of our blood flow product line during 2003. General and administrative expenses also decreased to $3.1 million for 2003 from $3.3 million in 2002 due again primarily to headcount reductions at the end of 2002 coupled with decreases in depreciation but offset by increases in marketing costs ($479,000) in support of the Quantix product line. "Our gamma business line improved in 2003 and the market remains very encouraging," said David Bupp, Neoprobe's President and CEO. "Our gamma product line continues to be the market leader and our primary marketing partner continues to experience positive sales momentum and strong product pricing. Net sales increased 45% in the fourth quarter of 2003 as compared to 2002. During 2003, we completed the pre-commercial and clinical evaluation activities associated with the commercial launch of the Quantix products. Following the presentation of the product at the recent Society of Thoracic Surgeons meeting, we have completed agreements with independent cardiovascular sales organizations to provide sales and marketing coverage for the Quantix products in North and South America, Europe and Asia. We were also able to obtain regulatory guidance during 2003 concerning the development plan for our procedural product Lymphoseek(TM). Finally, we have scheduled a meeting with the U.S. Food and Drug Administration in April to determine the appropriate next steps to reactivate the RIGS(R) technology development program." Neoprobe also announced that it intends to release the text of its Annual Letter to Stockholders tomorrow, March 10, 2004. The letter highlights Neoprobe's business and financial activities in 2003.
