EXHIBIT 99.1 BioSource International, Inc. Announces Record First Quarter Sales and Earnings CAMARILLO, Calif.--(BUSINESS WIRE)--April 23, 2004--BioSource International, Inc. (Nasdaq:BIOI), announced today its operating results for the first quarter ended March 31, 2004. Net sales for the quarter ended March 31, 2004, were a record $12.3 million, an increase of $1.4 million, or 13%, compared to net sales for the quarter ended March 31, 2003. The Company's revenues benefited by a $594,000, or 6%, positive impact of foreign exchange for the quarter ended March 31, 2004, when compared to the quarter ended March 31, 2003. The Company earned a net income for the quarter ended March 31, 2004, of $709,000, compared to net income of $103,000 for the quarter ended March 31, 2003. Earnings Before Interest, Taxes, Depreciation, and Amortization, or EBITDA, for the quarter ended March 31, 2004, was $1,519,000. "I am pleased with the progress we have made in the implementation of our more focused approach to our business," stated Mr. Terrance J. Bieker, President and Chief Executive Officer of BioSource. "Our 2003 actions to reduce operating costs in our Custom Business and our strategy of being more customer focused and selling higher margin products is beginning to take traction. I am particularly pleased that our organic sales growth in the first quarter of 2004 is more than double that of the fourth quarter of 2003." Mr. Bieker further commented: "Our long-term growth strategy is to focus and capitalize on our existing strength in cellular pathway assay kits (Cytokine and Signal Transduction) and to reposition our core biological and custom service capabilities to support that growth strategy." Sales of the Company's Signaling product lines grew 14% compared to the comparable prior-year quarter, from $2.3 million to $2.6 million. The Company's sales growth in its Cytokine product lines for the quarter grew 17%, from $4.9 million to $5.7 million. The Company's sales in its Custom product lines grew 7%, compared to the comparable prior-year quarter, from $3.7 million to $4.0 million. Gross profit margin was 56% for the three months ended March 31, 2004, and 57% for the three months ended March 31, 2003. The Company's increases in its Custom and European gross margins, when compared to the first quarter of 2003, were offset by a decline in gross margins in the U.S. The Company does not believe this is indicative of any trends and expects its gross profit margin to fluctuate somewhat during the remaining quarters of 2004. Research and development expense for the three months ended March 31, 2004 and 2003, was $1.4 million and $2.0 million and represented 11% and 18% of sales, respectively. The decrease of approximately $600,000 is related to reductions in payroll and related costs and general lab supplies and reflects the Company's efforts to align R&D investment to its core capabilities and new strategic direction. The Company anticipates its R&D expenses to moderately increase in the remaining quarters of 2004. Selling, marketing, and administrative expenses were $4.4 million for the three months ended March 31, 2004, and $4.0 million for the three months ended March 31, 2003, representing 36% of sales for both periods presented. This $400,000 increase is related to sales and marketing expenses increasing approximately $100,000 due to modest increases in payroll and office expenses and G&A expenses increasing approximately $300,000 due primarily to increases in benefits, legal, accounting, and other consulting fees. The Company anticipates its sales and marketing expenses to remain relatively constant throughout 2004, while its general and administrative expenses will rise slightly due to increases in benefits, legal, and accounting fees related to implementation of new regulatory requirements resulting from the Sarbanes-Oxley Act of 2002. The Company's effective income tax rate was 21%, with an income tax expense of $188,000 for the quarter ended March 31, 2004. The Company's income taxes have and may continue to fluctuate in the future depending on a number of factors, including the ability to use its deferred tax assets as of March 31, 2004. The Company believes it is more likely than not that it will be able to use those assets. In addition, the Company continues to benefit from R&D and other tax credits which, when applied to income levels for the periods presented, is resulting in effective tax rates lower than the current applicable federal and state statutory rates. "We intend to differentiate ourselves to our customers and to build value for our shareholders by leading certain high volume test markets, creating superior customer support annually, and consistently improving financial performance," stated Mr. Bieker. "We have a good start in 2004. We are maintaining our initial guidance of sales growth at between 8% and 10%, but increasing our guidance for EBITDA to a minimum of $3.75 million. Our strategic plan is designed for consistent, long-term improvement in annual revenues and EBITDA and to build shareholder value through improved financial performance."
