Energy Conversion Devices Files its Quarterly Report on Form 10-Q for Quarter Ended September 30, 2003

NASDAQ to temporarily change its trading symbol from ENER to ENERE.

ROCHESTER HILLS, Mich., Nov. 26 -- Energy Conversion Devices, Inc. (ECD Ovonics) announced that it has filed its Quarterly Report on Form 10-Q for the quarter ended September 30, 2003 with the Securities and Exchange Commission today.

On November 25, 2003, NASDAQ notified the Company that, as a result of the delayed filing of its Quarterly Report on Form 10-Q, NASDAQ will change the trading symbol for the Company's securities from ENER to ENERE at the opening of business on November 28, 2003.

The November 25, 2003 letter notified the Company of a NASDAQ staff determination indicating that the Company had failed to comply with the filing requirement for continued listing set forth in NASDAQ Marketplace Rule 4310(c)(14) due to the late filing of its Form 10-Q.

Because the Company has now filed the Form 10-Q, it expects NASDAQ to restore the trading symbol for its securities from ENERE to ENER after NASDAQ has confirmed and reviewed the filing of the Report on Form 10-Q.
