AMISTAR REPORTS FIRST QUARTER 2005 FINANCIAL RESULTS

SAN MARCOS, CALIFORNIA, May 5, 2005 /PR Newswire-First Call/ -- Amistar
Corporation (Nasdaq:-AMTA) today reported sales and results for the three months
ended March 31, 2005.

Net sales for the three months ended March 31, 2005 increased $1,494,000 or 49%
to $4,550,000, compared to $3,056,000 for the same quarter in 2004.

There was a net loss for the three months ended March 31, 2005 of $654,000 or
$0.21 per share compared to a net loss of $351,000 or $0.11 per share for the
same quarter in 2004.

The operating loss for the first three months of 2005 and 2004, respectively,
includes:

o        $248,000 and $210,000, for start-up and machine development costs
         related to the new ddn venture to provide automated equipment and
         systems to the retail pharmacy market.
o        $296,000 and $0, related to litigation defense costs for the lawsuit
         with Asteres, Inc.

The litigation with Asteres is currently in the discovery phase with a trial
date scheduled for September 2005. The Company believes it has strong defenses
and will continue to defend itself vigorously, including seeking dismissal in a
summary judgment hearing scheduled for July 2005.

"The AIA machine division sold nine machines during the current quarter and as
in the first quarter of 2004, started the year with a solid result. Although the
AMS division sales grew 85% with the addition of some new contracts, the margins
were affected adversely by inefficiencies related to early production of new
customer products. On the other hand, the Company, working jointly with our
majority-owned subsidiary ddn, has reached further milestones in our effort to
enter the emerging market for retail automation. During the current quarter, ddn
installed and tested an APM(TM) evaluation machine in a high- volume community
pharmacy. ddn plans to move to the next phase of market entry by installing an
evaluation unit in a mass merchant retail pharmacy site in the second quarter of
2005" stated Stuart Baker, Amistar's President.
