Exhibit 99-Press Release of Amistar Corporation dated August 4, 2004, reporting Amistar's financial results for the second quarter 2004. AMISTAR REPORTS SECOND QUARTER 2004 FINANCIAL RESULTS SAN MARCOS, CALIFORNIA, August 4, 2004 /PR Newswire-First Call/ -- Amistar Corporation (Nasdaq:-AMTA) today reported sales and results for the three and six months ended June 30, 2004. Net sales for the three months ended June 30, 2004 were $2,260,000 compared to $2,652,000 for the same quarter in 2003. Net sales for the six months ended June 30, 2004 were $5,316,000 compared to $5,421,000 for the same period in 2003. There was a net loss for the three months ended June 30, 2004 of $743,000 or $0.24 per share compared to a net loss of $79,000 or $0.03 per share in the second quarter of 2003. There was a net loss for the six months ended June 30, 2004 of $1,094,000 or $0.36 per share compared to a net loss of $225,000 or $0.07 per share in the same period in 2003. The loss in the current quarter was due primarily to start-up and machine development costs incurred by the Company's new subsidiary Distributed Delivery Networks Corporation ("ddn"), reduced gross margins resulting from a 26% decline in AMS division sales, lower sales from DataPlace(R) machines and lower margins earned on custom factory automation sales compared to the second quarter of 2003. During the quarter ended June 30, 2004, ddn incurred $386,000 in marketing, administrative, and machine development costs. Commenting on the results, Stuart Baker said, "The second quarter 2004 results were disappointing and further confirm the Company's strategic decision to pursue new markets with new innovative products. During the second quarter of 2004, the Company formed a new subsidiary, ddn, which initially will distribute a point-of-sale machine to retail pharmacies for dispensing finished prescriptions. During the current quarter, ddn achieved some important milestones. These milestones included attendance and the introduction of the APM(TM) machine prototype at the June National Association of Chain Drug Stores trade show".
