The firm's product and product-related revenues increased to $76.2 million in the quarter, up from $71.1 million in the third quarter of 2003. The sales included GeneChip array revenues of $37.5 million and instrument revenue of $16.4 million. Affymetrix noted that its installed base of GeneChip systems rose to more than 1,120 during the quarter.
Upon releasing its second-quarter results, Affymetrix had forecasted product and product-related revenues of $80 million to $85 million
Perhaps the most significant piece of news for Affymetrix during the quarter was the European Union clearance to market the firm's GeneChip platform for in vitro diagnostic purposes. It was the first marketing approval for Affymetrix and Roche under their collaboration to develop and sell molecular diagnostic products based on the GeneChip system. In tandem with Affymetrix's EU clearance, Roche received the CE Mark for its AmpliChip CYP450 drug-metabolism test.
For the full fiscal year, Affymetrix maintained its previous guidance for product and product-related revenues of $330 million to $335 million. However, the firm raised its earning-per-share guidance from $.60 to $.70.
