BASi Reports First Quarter 2006 Financial Results

WEST LAFAYETTE, Ind., February 14, 2006 BASi (Bioanalytical Systems, Inc.) (Nasdaq: BASI) today reported financial results for its first quarter of fiscal 2006, ended December 31, 2005. Revenue increased 1% to $9.8 million compared to $9.7 million for the quarter ended December 31, 2004. Net loss for the first quarter of fiscal 2006 was $716,000, or $0.15 per basic and diluted share, compared to a net income of $404,000, or $0.08 per basic and diluted share for the first quarter of fiscal 2005. The Company experienced delays in initiation of sizeable analytical chemistry projects, which negated significant improvements in the Company s toxicology and clinical research operations. Sales in the Company s products segment declined slightly, from $2.4 million to $2.3 million.

Cost of revenue for the quarter ended December 31, 2005 was $6.7 million, or 68% of revenue, compared to $6.1 million, or 63% of revenue, for the quarter ended December 31, 2004. Margins for the current fiscal quarter reflect the impact of lower utilization of the Company s laboratory facilities, where costs are relatively fixed, with revenue increases in operations which have lower margins.

The Company recently announced that it has implemented a program to process all laboratory samples generated by the Baltimore clinical research unit at its West Lafayette and other laboratories, relocating the equipment from Baltimore to the other laboratory sites. The Company expects this move to improve efficiency in its laboratory operations by increasing sample volume while reducing expenses at the Baltimore site.

Peter T. Kissinger, Chairman and CEO commented, First quarter results were disappointing, as our usually strong laboratory operations had a bad quarter due to postponement of work. This overshadowed some very significant improvements in our other operating units. We have continued to improve sales capabilities, and with the advantages we expect to gain from the lab consolidations, we anticipate improved results for the remainder of our fiscal year.
