C&D Technologies Reports Fiscal 2010

Third Quarter Results

Third Quarter Revenues, Unit Volume, Margins and Earnings All Sequentially

Improve Relative to Second Quarter

BLUE BELL, Pa., December 8, 2009 /PRNewswire-FirstCall/ — C&D Technologies, Inc. (NYSE: CHP - News), a leading North American producer and marketer of electrical power storage and conversion systems used in telecommunications, uninterrupted power supply systems, utility and other high reliability applications, today announced financial results for its fiscal 2010 third quarter ended October 31, 2009.

For the third fiscal quarter, the Company reported its second consecutive quarter of double-digit sequential revenue growth, with revenues of $91.2 million up, 10.7% from $82.4 million reported in this year’s second fiscal quarter. The sequential improvement in third fiscal quarter revenues was largely attributable to an approximately 5 percent growth in unit volume, principally driven by growth in Asia, as well as increased pricing due to higher commodity costs. Volumes in the third fiscal quarter were also up approximately 3 percent from the third fiscal quarter of last year, with commodity based price reductions correspondingly impacting revenues. In the third fiscal quarter a year ago, revenues were $93.8 million.

The Company also reported continued sequential improvement in quarterly earnings, with net loss of $3.4 million or ($0.13) per diluted share for the third quarter of fiscal 2010, a significant improvement from a net loss of $5.6 million, or ($0.21) per diluted share, in this year’s second fiscal quarter. The rate of sequential improvement was partially impacted by lags in the recovery of rising lead costs, higher warranty experience during the quarter and costs associated with the ramp-up of operations in Asia. In the comparable prior year third fiscal quarter, the Company reported a net loss of $146,000, or ($0.02) per diluted share.

Gross margins also continued their trend of steady sequential improvement, rising to 14.3% in the third fiscal quarter from 12.1% in the second fiscal quarter and 7.3% in the first fiscal quarter. This trend reflects improved pricing, improved sales mix and higher volumes, offset by the higher cost of lead in the third fiscal quarter.

Dr. Jeffrey A. Graves, President and CEO, said, “In the third fiscal quarter, we continued to achieve volume growth and margin improvement, encouraging signs that the implementation of our strategy has fundamentally strengthened the business and provided us with a clear path to profitability. Despite persistent economic challenges, we grew unit volumes both sequentially and in comparison to the year ago quarter, reflecting the success of our products in targeting new vertical and geographic markets. In particular, the introduction of new products now manufactured in our China facility has led to significant and continued growth in our Asian business during the year. For the second consecutive quarter, we managed to expand margins through mix optimization and cost management programs, despite the transient impact on margins from commodity price volatility. We are confident that we are establishing a strong foundation from which we can leverage C&D’s reputation for innovative technological leadership, reliability, and product quality into further strong growth and improved returns for our shareholders.”

Dr. Graves continued, “Over the course of the current fiscal year, we have made significant progress building a stronger, more agile company despite the severe economic challenges to our end markets from weak overall global economic conditions. With our investments in manufacturing expansion and new product development, we have achieved real growth and consistent margin expansion over the last few quarters, resulting in an improving bottom line. All of these accomplishments highlight effective

implementation of our strategy as we look to expand the value of the C&D franchise. The trajectory and timing of an enhanced earnings improvement that was expected to accompany our progress was affected late in the third quarter by the time lag between rising lead costs and customer price adjustments. Based upon current stable market conditions and our accelerating new product sales throughout the world, we anticipate continuing improvements in our operating margins in our fiscal fourth quarter, and in the coming new year. However, the rise in commodity costs, particularly lead prices that occurred in the late summer time frame, will continue to be a drag on margins in the fourth quarter. Taking into account our typical pricing recovery cycle of three to six months, which is largely driven by contracted price adjustments with our largest customers, we now believe that it is more likely that our return to profitability will occur in the first quarter of our next fiscal year.”

Dr. Graves concluded, “We are extremely confident that C&D is well positioned in the market to capitalize on the growing world-wide demand for standby power, and further that these energy storage needs are expected to greatly accelerate as the global economy recovers. Through our continued focus on innovative new products, improved manufacturing efficiency and productivity, and world-leading customer service, we believe we can leverage this future demand growth into strong returns for our shareholders in the years ahead.”
