FOR IMMEDIATE RELEASE – January 23, 2004

CINERGY REPORTS 2003 RESULTS OF $2.63 PER SHARE
DESPITE MILD WEATHER

CINCINNATI – Cinergy Corp. (NYSE:CIN) today reported 2003 earnings of $2.63 per share on a diluted basis, despite a $0.17 per share reduction from last year due to milder than normal weather during much of 2003.

During the year, the company recorded gains of $0.20 from the cumulative effect of changes in accounting principles and discontinued operations.  Cinergy also incurred $0.11 per share in charges for the completion of a 2003 voluntary early retirement and severance program, a write-off of a technology investment and the resolution of Enron bankruptcy claims.

The $2.63 per share for 2003 compares with earnings of $2.13 per share on a diluted basis in 2002, which included losses of $0.21 from the cumulative effect of changes in accounting principles and discontinued operations, and other previously reported charges totaling $0.34.

For fourth quarter 2003, Cinergy’s earnings were $0.59 per share, including a $0.01 charge associated with the completion of a 2003 voluntary early retirement and severance program.  This compares with $0.58 per share in the same quarter of 2002, which included a loss from discontinued operations of $0.15 per share and other previously reported charges of $0.05 per share.

“While 2003 was a challenging year in the energy industry, our strong fundamentals have enabled us to continue delivering solid value, allowing us to increase the common stock dividend last week by 2.2 percent to an annual rate of $1.88 per share,” said James E. Rogers, chairman, president and chief executive officer.  “Our continued emphasis on operating excellence has given us the ability to perform well despite mild weather and a sluggish economy.”

Fourth quarter earnings from the Regulated Operations segment were $0.26 per share, a decrease of $0.29 per share over last year’s fourth quarter results.  Contributing to the decrease were lower gross margins due to mild weather and the economy, higher financing and depreciation costs, and an increase in the state of Indiana income tax rate.

Commercial Businesses’ earnings for the fourth quarter were $0.34 per share compared with $0.09 per share for the fourth quarter of last year, which included a loss from discontinued operations of $0.15 per share and other previously reported charges of $0.01 per share.  The $0.09 per share increase is primarily attributable to increased profits from the generation and supply contracts area, lower operating and administrative expenses, and lower financing and depreciation costs.

The Power Technology and Infrastructure Services segment lost $0.01 per share in the fourth quarter, a $0.01 per share improvement from the prior year excluding previously reported charges of $0.04 per share.

Hearings were completed in November at the Indiana Utility Regulatory Commission on PSI Energy’s application for an increase in rates of approximately $180 million, and a decision is expected in the first quarter of 2004.  The proposed increase would reflect in rates major construction projects related to environmental compliance, growing power demands of its customers and transmission and distribution system improvements to maintain reliable service.

In December, the Kentucky Public Service Commission approved a long-term electric supply plan for The Union Light, Heat and Power Co.’s Northern Kentucky service territory, under which ULH&P’s parent company, The Cincinnati Gas & Electric Co., will transfer ownership of approximately 1,100 megawatts of electric generating capacity to ULH&P.  The capacity is currently part of the fleet of CG&E generating assets used to serve ULH&P under a multi-year wholesale power supply contract.  Next, the company must seek the approval of the Federal Energy Regulatory Commission and the Securities and Exchange Commission.  The PSC’s decision urged these agencies to give consideration to the Kentucky PSC’s findings that the proposed transaction is in the best interest of ULH&P’s customers.
