Performance Technologies Updates Guidance for the Second Quarter 2009

ROCHESTER, N.Y., July 7 /PRNewswire-FirstCall/ -- Performance Technologies,
Inc. (Nasdaq: PTIX) today updated its guidance for the second quarter 2009.

For the second quarter 2009, the Company expects to report a loss in the range
of ($.08) per share to ($.10) per share. This updated guidance includes a
discrete income tax benefit of $.01 per share but does not include stock
compensation expense of $.01 per share. The Company's guidance had indicated
a range of loss between ($.06) per share and ($.01) per share, not including
stock compensation expense. The larger than expected loss is due to lower
than anticipated revenue. When it reports, the Company expects second quarter
revenue to be in the range of $6.2 million to $6.6 million.

"When we issued our guidance for the second quarter, we noted that although
the predictability of the timing of customer orders in the present economic
climate was most challenging, we would continue to provide our best forward
view to our stockholders," said John Slusser, president and chief executive
officer. "Unfortunately, while product interest remains strong, several
anticipated orders were delayed past quarter end. In these ongoing difficult
economic conditions, we will continue to prudently manage our costs while we
also invest in our strategic initiatives for the future."

The Company's balance sheet continues to be very strong with cash and
investments amounting to approximately $31.6 million, or $2.85 per share, and
the Company had no long-term debt at June 30, 2009.

Management will provide more details surrounding this guidance update on the
Performance Technologies' second quarter earnings conference call which will
be scheduled later this month.

The Private Securities Litigation Reform Act of 1995 provides a "safe harbor"
for certain forward-looking statements. This press release contains
forward-looking statements which reflect the Company's current views with
respect to future events and financial performance, within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934 and is subject to the safe harbor provisions of those
Sections. The Company's future operating results are subject to various risks
and uncertainties and could differ materially from those discussed in the
forward-looking statements and may be affected by various trends and factors
which are beyond the Company's control. These risks and uncertainties include,
among other factors, business and economic conditions, rapid technological
changes accompanied by frequent new product introductions, competitive
pressures, dependence on key customers, inability to gauge order flows from
customers, fluctuations in quarterly and annual results, the reliance on a
limited number of third party suppliers, limitations of the Company's
manufacturing capacity and arrangements, the protection of the Company's
proprietary technology, the dependence on key personnel, changes in critical
accounting estimates, potential impairments related to goodwill and
investments, foreign regulations, and potential material weaknesses in
internal control over financial reporting. In addition, during weak or
uncertain economic periods, customers' visibility deteriorates causing delays
in the placement of their orders. These factors often result in a substantial
portion of the Company's revenue being derived from orders placed within a
quarter and shipped in the final month of the same quarter. The Company
