Revenues for the third quarter of fiscal 2005 were $4.1 million, compared to $3.9 million in the third quarter of fiscal 2004 and $2.8 million in the previous quarter. Net loss for the quarter was $96,000, or $0.01 per share, compared to net profit of $185,000, or $0.01 per diluted share a year ago and net loss of $858,000, or $0.06 per share in the previous quarter.

Revenues for the first nine months of 2005 were $11.2 million compared to $10.8 million for the first nine months of 2004. Net loss for the first nine months of 2005 was $613,000, or $0.04 per share compared to a net loss of $108,000 or $0.01 per share for the first nine months of 2004.

"The solid level of business activity that we experienced early in the third quarter continued throughout the period," said Gilbert Hu, AltiGen's President and CEO. "Our results reflect the strategy we undertook earlier this year to simplify our product bundling. We also reinforced the competitive advantage of this package by including AltiView software, which offers more features than other products on the market. Our resellers responded positively to this initiative, which has been effective at driving growth and expanding our footprint. We believe the success of this strategy bodes well for future business as it also increases prospects for follow on sales.

"In addition, we continued to make progress in targeted areas including the banking vertical where we saw new installations more than quadruple in the June quarter. Moreover, penetration of our AltiContact Manager (ACM) in the call center market is now contributing to a meaningful portion of our overall results. During the last period, sales of these call center systems increased 36% sequentially.

"We are very encouraged by the rebound in revenues as well as our customers' reception to our new pricing and packaging strategy. Currently, we see this positive momentum continuing, and we look forward to reporting our progress," concluded Mr. Hu.

Phil McDermott, AltiGen's Chief Financial Officer, commented, "We are pleased to deliver improved performance this quarter. We continue to conservatively manage our expenses, at the same time maximizing opportunities to extend our market reach. AltiGen's financial position remains solid with $9.1 million in cash and short-term investments and zero debt."
