AMISTAR REPORTS FIRST QUARTER 2006 FINANCIAL RESULTS

SAN MARCOS, CALIFORNIA, May 22, 2006 /PRIMEZONE/ -- Amistar Corporation (OTC
Bulletin Board-AMTA.OB) today reported sales and results for the three months
ended March 31, 2006.

The Condensed Consolidated Statements of Operations included in this release
reflect the AMS operating results presented as a discontinued operation.

Net sales for the three months ended March 31, 2006 decreased $410,000 or 36% to
$721,000, compared to $1,131,000 for the same quarter in 2005.

There was a net loss from continuing operations for the three months ended March
31, 2006 of $1,005,000 or $0.32 per share compared to a net loss from continuing
operations of $608,000 or $0.20 per share for the same quarter in 2005. The
income from discontinued operations was $87,000 for the three months ended March
31, 2006 compared to a $46,000 loss during the same period in 2005.

The operating loss from continuing operations for the three months ended March
31, of 2006 and 2005, respectively, includes:

    o    $337,000 and $248,000, for start-up and machine development costs
         related to the new Distributed Delivery Networks venture to provide
         automated equipment and systems to the retail and other pharmacy
         markets.
    o    $83,000 and $296,000, related to litigation defense and counter-suit
         costs for the lawsuit (now settled) with Asteres, Inc.



The income from discontinued operations for the three months ended March 31,
2006 increased over the loss from discontinued operations during the same period
in 2005, due primarily to an $16,000 gain on sale of equipment and due to lower
personnel and facility costs in the three months ended March 31, 2006.

"The first quarter sales and gross margin were lower than our expectation due
primarily because two large orders for distributed and custom factory automation
machinery were not completed in the first quarter and are now expected to be
completed in the second quarter of 2006."

"The Company, working jointly with our majority-owned subsidiary Distributed
Delivery Networks, has reached further milestones in our effort to enter the
emerging market for point-of-sale automation. During the first quarter we 1)
continued to make machine hardware and software improvements to the APM(TM)
resulting from data gathered during our beta tests in community and chain retail
pharmacies, and 2) made machine hardware and software enhancements allowing us
to offer the APM for use in an alternative market", stated Stuart Baker,
Amistar's President.
