C&D Technologies Regains Compliance with NYSE Continued Listing Standard

BLUE BELL, Pa., June 3, 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 (UPS) systems, utility and other high reliability applications, today announced it has been notified by the New York Stock Exchange (the “NYSE”) that it is deemed to be in compliance with the NYSE’s continued listing standard.

C&D was previously notified by letter dated April 22, 2009 from the NYSE that the Company had fallen below the NYSE continued listing criterion that requires 30 day average market capitalization of not less than $75 million and total stockholders’ equity of not less than $75 million. The NYSE received approval from the Securities and Exchange Commission (the “SEC”) for a pilot program, effective retroactively to May 12, 2009, that would lower the numeric thresholds for this requirement to $50 million. The pilot program would be effective through October 31, 2009, with a subsequent rule filing anticipated prior to this date to make this a permanent continued listing standard change.

As a result of the aforementioned pilot program, C&D is deemed to be in compliance with the NYSE continued listing requirement that pertains to market capitalization and stockholders’ equity, which has now effectively been reset to a $50 million threshold level.
