EXHIBIT 99.1 PRESS RELEASE: BIO-LOGIC REPORTS $0.06 PER SHARE EARNINGS FOR FIRST QUARTER Receives FDA Clearance for Stacked ABR Launches Major Educational Marketing Initiative in Hearing Diagnostics and Infant Screening MUNDELEIN, IL, June 19, 2003 - Bio-logic Systems Corp. (Nasdaq: BLSC), a designer and marketer of computerized medical electro-diagnostic equipment and disposables, today reported financial results for the fiscal 2004 first quarter ended May 31, 2003. Net sales for the first quarter decreased 13 percent to $6.3 million, compared with $7.2 million for the same quarter a year ago, due to lower sales in the company's Neurology business. Gross profit margin increased to 69.3 percent from 68.1 percent, due mainly to continued improvement in cost management. Total operating expense for the quarter was $4.0 million, compared to $4.3 million reported last year. The decrease was due to lower selling, general and administrative expenses, partially offset by lower net capitalized costs in research and development. Operating income for the quarter was $379,000 compared to $612,000 for the same quarter last year. Net income for the quarter was $274,000 or $0.06 per diluted share, compared to $388,000 or $0.09 per share in the first quarter of fiscal 2003. Cash at the end of the quarter was $9.8 million, a $.8 million decrease from the balance at the company's February 28, 2003 fiscal year end, due primarily to a reduction in accounts payable. Book value per share grew to $4.42, up from $4.36 at the end of the fiscal year. "Sales and income for the quarter were down compared to last year due to lower worldwide Neurology sales, which we believe to be a temporary deferral of orders that will come through later in the year," commented Roderick G. Johnson, president and chief operating officer. "Although Neurology had a difficult quarter, we continued to enjoy solid sales on the Hearing side of the business. Domestically, strong diagnostic systems and disposables growth, led by the Ear Muffin(TM) and our proprietary Tree Tip(TM), basically offset lower sales of infant screening products in this maturing market. International also showed good growth across all major product lines, including infant screening and diagnostic systems. "There were some positive developments in the quarter that we expect to favorably impact sales later in the year. In May, we received FDA 510(k) clearance for Stacked ABR, a product that enables ENT physicians and audiologists to screen patients in their offices for auditory nervous system abnormalities. This technology offers significant savings compared to the more costly alternative of undergoing a MRI procedure. We also released a new patent-pending adapter enabling the Ear Muffin to be used across all competitor product lines, allowing for further penetration of this significant base of disposables business. A recent revision also added the Ear Muffin to our Novation hospital alliance contract, which now provides member hospitals a choice of over-the-ear disposable earphones. "In addition, we launched a new marketing initiative aimed at educating users in the latest technologies and thinking in hearing diagnostics and infant screening through a seminar program being held in 23 cities throughout the U.S., as well as in selected international markets. These seminars utilize a world-class faculty of leading clinical practitioners and researchers, and emphasize our M.A.S.T.E.R(TM) software, used to characterize an infant's hearing loss, and Stacked ABR. The five domestic and nine international seminars held to date have been both well attended and well received. We anticipate that this program, coupled with the continued innovation and enhancement of our Hearing product line, will enable us to make further market gains in this area in the future," Johnson concluded.
