Amistar's financial results for the first quarter 2003.


         AMISTAR REPORTS FIRST QUARTER 2003 FINANCIAL RESULTS

SAN MARCOS, CALIFORNIA, April 23, 2003 (PR NEWSWIRE) -- Amistar Corporation
(NASDAQ\SC-AMTA) today reported sales and results for the three months ended
March 31, 2003.

Net sales for the three months ended March 31, 2003 were $2,769,000 compared to
$2,641,000 for the comparable quarter in 2002.

There was a net loss for the three months ended March 31, 2003 of $146,000 or
$0.05 per share compared to a net loss of $102,000 or $0.03 per share in the
first quarter of 2002. The loss for the prior year quarter ended March 31, 2002
included a $400,000 income tax carry-back refund benefit.

The loss before income taxes for the three months ended March 31, 2003 was
$145,000 compared to a net loss of $500,000 for the first quarter of 2002.
During the quarter ended March 31, 2003, the Company narrowed its loss before
income taxes compared to the previous quarters in 2002 primarily due to an
increase in DataPlace label placement machine and custom factory automation
equipment sales, the effects of cost cutting in prior quarters, and due to
increased manufacturing efficiencies in the Amistar Manufacturing Services
division.
