PDSI REPORTS IMPROVED SALES

FOR 2006 FIRST QUARTER

COLUMBUS, Ohio (April 26, 2006) – Pinnacle Data Systems, Inc. (PDSi) (AMEX: PNS) today announced results for the first quarter ended March 31, 2006.

Sales for the first quarter of 2006 totaled $15.0 million, a 100% rise from $7.5 million for the first quarter of 2005. This increase was attributable to the 2005 acquisition and organic growth.

Gross profit for the first quarter of 2006 was $2.8 million, a 40% increase compared to $2.0 million for the comparable period of 2005. This increase was due to new programs and the 2005 acquisition, which was partially offset by the change in the product mix coupled with an inventory write-down of approximately $100,000 due to implementation of Restriction of Hazardous Substances (RoHS) standards.

Operating expenses, including selling, general and administrative (SG&A) expenses for the first quarter of 2006 totaled $3.5 million, a 121% increase compared to $1.6 million for the first quarter of 2005. Expressed as a percentage of sales, SG&A expenses were 24% and 21% for the

first quarters of 2006 and 2005, respectively. SG&A expenses for the first quarter of 2006 included $400,000 of one-time severance expenses relating primarily to the previously announced resignation of Chris Winslow, PDSi’s former President and Chief Operating Officer.

For the first quarter of 2006, the net loss was $518,000, or ($0.09) per diluted share versus net income of $247,000, or $0.04 per diluted share, for the first quarter of 2005.

Michael R. Sayre, President and Chief Executive Officer, stated, “While we are pleased with the record first quarter sales, our results were particularly affected by expected first quarter shipments moving into the second quarter and one-time inventory and SG&A expense items. Positive contributions continue to be realized from our 2005 acquisition as well as organic sales growth. We anticipate stronger sales in the second quarter and that 2006 will be another record year of sales for the Company.”

Mr. Sayre continued, “Progress continues to be achieved regarding implementation of our growth strategy, which includes expanding the breadth of services and solutions to Global Fortune 500 customers and additional reinvestment in our business to realize further efficiencies and increased scalability. Our growing technology and services portfolio strengthens PDSi’s capabilities and competitive advantage, which will benefit us in our transition toward becoming a global professional services company. These efforts include a fully integrated approach to linking our services to create a compelling solution for Original Equipment Manufacturers with expanded partnerships, capabilities and geographic reach.”

Additional Operating Results

For the first quarter of 2006, product sales totaled $12.4 million, an increase of 134% from $5.3 million in the first quarter of 2005. Gross profit on products increased to $1.3 million, (10% of sales), in the first quarter of 2006 from $822,000, (15% of sales), in the same quarter last year due to a change in mix.

For the first quarter of 2006, service sales totaled $2.6 million, an increase of 17% from approximately $2.2 million in the first quarter of 2005, due to new programs as a result of the 2005 acquisition. Gross profit on service sales for the 2006 first quarter totaled $1.5 million, compared to $1.2 million for the same period in 2005. The gross profit margin on service sales improved to 58% in the first quarter of 2006 from 55% in the 2005 first quarter.
