Pressure BioSciences, Inc. Reports First Quarter 2008 Financial Results and Provides Business Update

SOUTH EASTON, Mass., May 1 /PRNewswire-FirstCall/ -- Pressure BioSciences, Inc. (Nasdaq: PBIO) ("PBI") today announced that total revenue for the first quarter of 2008 was $132,376 compared to $131,621 for the comparable period in the prior year. Revenue from the sale of PCT products and services was $81,473 for the three months ended March 31, 2008 as compared to $37,943 for the prior year period. During the first quarter of 2008, we completed the installation of seven PCT Sample Preparation Systems ("PCT Systems"), as compared to one in the first quarter of 2007. Also contributing to the increase in revenue was an increase in the number of PULSE Tubes and ProteoSolve-lrs kits sold. The Company also recorded $50,903 of grant revenue during the first quarter of 2008 as compared to $93,678 in the same period in the prior year. This decrease in grant revenue was due to a shift in resources from grant related activities to other research and development projects.

Edward H. Myles, Senior Vice President of Finance and CFO commented: "During the first quarter of 2008, we completed the installation of seven PCT Sample Preparation Systems. Four of these installations were under lease and rental agreements; therefore, the revenue will be recognized over the life of each respective agreement. The remaining three installations were outright sales of our PCT Systems."

Mr. Myles continued: "As noted previously, our stated commercialization strategy is centered upon increasing the installed base of PCT Sample Preparation Systems so that we can continue to realize increases in our recurring revenue streams from PULSE Tubes, ProteoSolve-lrs kits, and extended service contracts. During the first quarter of 2008, we saw an increase in sales of our PULSE Tubes and ProteoSolve products. We believe this is an indication that scientists who have adopted our technology are using PCT to address their sample preparation needs for a greater portion of their experiments."

Richard T. Schumacher, Founder, President, and CEO of Pressure BioSciences, Inc. said: "The number of installations during the first quarter of 2008 was essentially flat when compared to Q3 and Q4 of 2007. However, we are very encouraged by the feedback that we are receiving from the field and from the data being generated in our laboratories and in the laboratories of our collaborators. We are also encouraged by the increase in consumable PCT products sales."

Mr. Schumacher continued: "The number of calls we have received related to our PCT product line has continued to increase, as has the number of requests for PCT System quotations for grant submissions. We have made measurable progress on our 2008 goals related to the development of a new PCT instrument, a new PCT consumable, and a new ProteoSolve kit. Our sales team is benefiting tremendously from the leadership of our newly hired (February 25, 2008) Vice President of Sales, Mr. Matthew Potter. We look to the remainder of 2008 with enthusiasm as we believe our achievements in the first quarter of 2008 position us well to accomplish our 2008 commercialization goals of converting research scientists who are excited about our technology into revenue-generating customers and active supporters of the PCT Sample Preparation System."
