EXHIBIT 99.1 BioSource Reports Second Quarter 2004 Financial Results CAMARILLO, Calif.--(BUSINESS WIRE)--July 26, 2004--BioSource International, Inc. (Nasdaq:BIOI) today announced financial results for its second quarter ended June 30, 2004. For the second quarter ended June 30, 2004, the Company reported net sales of $12.0 million, compared with net sales of $11.7 million for the second quarter of 2003. In the second quarter of 2004, foreign currency translations favorably impacted revenues by $0.3 million. Net income for the second quarter of 2004 was $0.4 million, or $0.05 per share, as compared with net income of $0.3 million, or $0.03 per share, for the 2003 second quarter. For the six months ended June 30, 2004, net sales were $24.2 million, a 7% increase as compared to net sales of $22.6 million for the first six months of fiscal 2003. Without the beneficial impact of foreign exchange for the six months ended June 30, 2004, net sales would have grown 3%. Net income for the first six months of fiscal 2004 was $1.2 million, or $0.12 per share, as compared with net income for the first six months of fiscal 2003 of $0.4 million, or $0.04 per share. Terrance J. Bieker, President and CEO, stated "We are pleased with the increase in our cellular pathway assay kit sales and substantial improvement of our earnings year to date compared to 2003." Mr. Bieker continued, "This further reinforces our confidence that our focus on cellular pathway assays and their related biologicals is the correct strategy to build long term shareholder value." Second Quarter Review Sales of the Company's cellular pathway assay products increased 8% and 13% for the three and six months ended June 30, 2004, respectively, compared to the same periods in the prior year. Related biologicals product sales decreased 1% during the second quarter of 2004 but increased 7% for the first half of 2004 compared to 2003. This growth was partially offset by a 3% decrease in sales of other product lines during the second quarter of 2004 as compared to the same period in 2003, although sales for other products were unchanged for the first six months of 2004 compared to the first half of 2003. The Company's second quarter distributor sales decreased 6% compared to the comparable period in the prior year due to reduced sales in France and Japan. Cost of goods sold increased to $5.5 million in the second quarter of 2004 from $5.4 million in the second quarter of 2003. The gross margin of 54% remained unchanged compared to the second quarter of 2003. Operating expenses in the second quarter were as follows: -- Research and development expenses were $1.4 million in the second quarter of 2004 as compared with $1.9 million in the comparable quarter of 2003. This decrease was primarily due to headcount reduction and related costs and is consistent with the Company's strategy of focusing its R&D investments on its core strength of assay development. -- In the second quarter of 2004, sales and marketing expenses of $2.4 million were relatively consistent with the second quarter of 2003 costs of $2.5 million. -- General and administrative expenses increased from $1.4 million in the second quarter of 2003 to $2.1 million in the second quarter of 2004. This increase was primarily due to increases in payroll, benefits and professional fees, as well as the one-time costs associated with the resignation of our former chief financial officer. -- The Company's effective tax rates for the three and six months ended June 30, 2004 were (10%) and 11%, respectively. During the second quarter of 2004 the IRS concluded an audit of certain tax returns and as a result the Company reversed approximately $0.1 million in reserves which benefited its income tax provision as a result of the favorable outcome of the examination. Excluding the impact of the reversal of the aforementioned income tax exposure reserve, the Company's effective tax rate for the three and six months ended June 30, 2004 would have been approximately 21% for each period. At June 30, 2004, the Company's cash and cash equivalents totaled $5.0 million.
