CSP INC. REPORTS 40% SALES INCREASE
FOR FIRST-QUARTER FISCAL 2007

BILLERICA, MA, March 07, 2007 - CSP Inc. (NASDAQ: CSPI), a provider of IT solutions, systems integration services and dense cluster computing systems, today reported financial results for the first quarter of fiscal 2007 ended December 31, 2006.

For the first quarter of fiscal 2007, CSP Inc. sales increased 40% to $21.1 million from $15.1 million in the first quarter of fiscal 2006. Net income for the first quarter of fiscal 2007 was $978,000, or $0.25 per diluted share, compared with a net loss of $546,000, or $0.15 per diluted share, in the first quarter of fiscal 2006.

"CSP began fiscal 2007 with excellent first-quarter performance across the board, reporting a 40% increase in sales versus the first quarter of fiscal 2006 and a profit of $978,000," said Alexander R. Lupinetti, chairman and chief executive officer of CSP Inc. "Strong MultiComputer systems sales and robust demand for our IT systems integration services and best-of-breed IT solutions drove revenue and net income growth."

"CSP's Systems segment performed very well in the first quarter, primarily as a result of MultiComputer systems shipments to Raytheon," added Lupinetti. "The shipments were part of a previously announced $17 to $18 million contract award to supply FastCluster 220R MultiComputer Systems. We expect to deliver the remainder of the systems during the current fiscal year."

"After the close of the quarter we completed an agreement to resell Annapolis Micro Systems' Field Programmable Gate Array (FPGA) technology," said Lupinetti. "Our commercial and government customers now can leverage Annapolis' innovative design and development tools on an FPGA integrated chip within our FastCluster rugged computing platform. This hybrid FastCluster computing environment, which is capable of supporting hundreds of hybrid compute blades, includes a broad set of libraries, diagnostics and development tools that promote collaboration, productivity and portability. We are excited to be teamed with a recognized leader in FPGA technology to offer this hybrid computing platform."

"MODCOMP also reported excellent results for the first quarter. Systems and Solutions Division (SSD) sales were strong, driven by robust demand in the market for quality integrated IT infrastructure solutions," said Lupinetti. "The previously announced loss of our reseller relationship with Dell Inc. had minimal effect on sales in the first quarter as we essentially replaced the business derived from the relationship by teaming with other partners. We continue to grow this business by capitalizing on our technical expertise and productive sales model."

"MODCOMP's German subsidiary also performed well in the quarter," added Lupinetti. "Our margins at this business were especially strong as a result of two unusually high-margin professional consulting contracts. We also are seeing the benefits of our restructuring in Germany last year. The economic outlook in Germany is positive and we are encouraged by our prospects going forward."

"We began fiscal 2007 with a strong quarter and we are enthusiastic about CSP's outlook for the year. Our investments in technology and people are enabling us to capitalize on demand in our markets," concluded Lupinetti.
