Performance Technologies Announces

First Quarter 2007 Financial Results

ROCHESTER, NY – April 26, 2007 -- Performance Technologies, Inc. (NASDAQ: PTIX), a leading developer of communication platforms and systems, today announced its financial results for the first quarter 2007.

Financial Information

Revenue in the first quarter 2007 amounted to $9.4 million, compared to $12.2 million in the first quarter 2006.

Net loss for the first quarter 2007 amounted to $.6 million, or $.05 per basic share, including stock-based compensation expense of $.2 million, or $.01 per share, based on 13.2 million shares outstanding. Net income for the first quarter 2006 amounted to $.5 million, or $.04 per diluted share, including restructuring charges related to closing of the Company’s Norwood engineering center amounting to $.4 million, or $.02 per share, and stock-based compensation expense amounting to $.1 million, or $.01 per share, based on 13.3 million shares outstanding.

At March 31, 2007, cash and investments amounted to $37.0 million, or approximately $2.80 per share, and the Company had no long-term debt.

Business Overview

The Company targets three vertical markets for its products: telecommunications, aerospace and defense, and commercial. Of the three vertical markets served, telecommunications is the largest and represented approximately 75% of the Company’s business in 2006.

The telecommunications market served by the Company depends upon carrier spending to upgrade network infrastructure to next-generation equipment. It is management’s view that the consolidation in the telecommunications industry and a softening of carrier spending, particularly in the United States, impacted the Company’s performance as well as our customers and peers during the first quarter 2007.  

Despite the overall weakness in the telecommunications market, management is seeing increasing sales activity in selective areas within the communications market. One such market requirement is for signaling over IP transport solutions among Tier 2 and Tier 3 carriers in the U.S. In addition, during the first quarter 2007, we hired an experienced sales person to focus on selling our SEGway™ signaling products into Eastern Europe and Central America. Both regions show promise for our SEGway products and distributor relationships have already been established in each of these regions.

We are also seeing numerous new communications opportunities for aerospace and defense network applications. The U.S. Government has begun initiatives to upgrade their current communications infrastructure and to build-out new communications networks over IP. We are working with numerous prime contractors who are designing our Advance Management Platforms™ into these network architectures. During the first quarter 2007, we shipped platform products for seven such aerospace and defense programs.

These business opportunities in signaling, aerospace and defense appear to have shorter sales cycles to revenue than in the traditional embedded telecommunications equipment market we serve.

“Our first quarter financial performance was in line with our projections and reflected expected softness in the telecom market. We anticipate this softness to continue into the second quarter,” said John Slusser, president and chief executive officer. “In the interim, we are proceeding with multi-faceted initiatives to position the Company for long-term growth. These initiatives include ongoing enhancement to our Embedded Systems Group’s value proposition of a tightly integrated solution set, an increased focus on aerospace and defense opportunities for our platform products, continued investment in our Signaling Systems Group, and actions to better maximize our return on our considerable IP-packet and carrier-grade Linux core technologies.”

As part of a $10 million stock buy-back plan authorized by the Board of Directors, during the past sixty days, the Company has purchased approximately 400,000 shares of its common stock in the open market with an aggregate value of approximately $2.0 million.

Guidance

During weak or uncertain economic periods, the visibility of customer orders is limited. This lack of customer visibility often results 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. At the current time, forward-looking visibility of customer orders is very limited.

The Company provides guidance only on earnings per share expected in the next quarter. Because the Company is anticipating low order volumes from its two largest customers, both selling into the U.S. carrier market, and expects to increase its signaling investments, management anticipates a loss in the second quarter 2007 in the range of $.02 to $.06 per share. This estimated loss per share excludes restructuring charges, stock-based compensation expense and discrete income tax items. In the second quarter 2007, stock-based compensation expense is expected to be approximately $.1 million, excluding any stock options granted during the quarter.

The Company works closely with customers to incorporate its platforms, blades and software solutions into their product designs. Such ”design wins” have been a useful metric for management to judge the Company's product acceptance in its marketplace. Design wins in our traditional embedded communications equipment market, if successfully deployed by our customers, reach production volumes at varying rates, generally beginning twelve to eighteen months after the design win occurs. A variety of risks such as schedule delays, cancellations, changes in customer markets and economic conditions can adversely affect a design win before production is reached or during deployment.

During the first quarter 2007, the Company realized two design wins for its Advanced Managed Platform products. Each design win has the potential to generate at least $.5 million of annualized revenue when and if production volumes are reached.

More in-depth discussions of the Company's strategy and financial performance can be found in the Company's periodic reports on Form 10-K and Form 10-Q, as filed with the Securities and Exchange Commission.
