(TEXAS GENCO LETTERHEAD) FOR IMMEDIATE RELEASE Page 1 of 2 - -------------------------------------------------------------------------------- TEXAS GENCO REPORTS STRONG 3RD QUARTER 2003 RESULTS COMPANY RAISES 2003 EPS ESTIMATE AND PROVIDES INITIAL 2004 EARNINGS GUIDANCE HOUSTON - OCTOBER 21, 2003 - Texas Genco Holdings, Inc. (NYSE: TGN), an 81 percent-owned subsidiary of CenterPoint Energy, Inc. (NYSE: CNP), today reported net income of $82 million, or $1.03 per share for the quarter ended September 30, 2003, compared to net income of $3 million, or $0.04 per share, for the same period of 2002. The company raised its full-year 2003 earnings per share estimate to $1.50-$1.60 from its prior expectation of achieving the high end of $1.10-$1.30 per share. This revised earnings guidance reflects the strong year-to-date results, the higher capacity auction prices contracted for the remainder of the year and the return to service of two baseload generating units. The company also indicated that it currently has in excess of $700 million of capacity revenues under contract for 2004, including approximately 70 percent of its available baseload capacity. Taking these forward sales into consideration, the company provided initial 2004 earnings guidance of $2.75-$3.25 per share. However, the company emphasized that a portion of these forward sales occurred when natural gas prices were higher than current natural gas prices. Since baseload capacity product prices are influenced significantly by natural gas prices, future period revenues will be highly dependent on natural gas prices. "Our earnings improvement this quarter was again driven by higher wholesale electricity prices in our market," said David Tees, president and chief executive officer of Texas Genco. "I am also very pleased that two of our solid fuel baseload generating units were returned to service in the quarter," stated Tees. "I'm very proud of our employees who worked diligently to return these units to service safely and in a minimal amount of time. Our entire workforce remains focused on doing what they do best -- running efficient, safe and reliable plants." Wholesale electricity prices were much higher in 2003 due to substantially higher natural gas prices which led to increased capacity auction revenues for the company's baseload products. Energy revenues also increased, which more than offset an increase in fuel costs. Operation and maintenance expenses increased by $2 million due to higher pension and employee benefit expenses and costs associated with unplanned outages at Unit 1 of the South Texas Project nuclear facility and at Unit 8 of the W. A. Parish coal plant, which were partially offset by a reduction in technical support costs. Both units were returned to full service during the quarter. The company estimated that the added cost of replacement energy associated with the unplanned outages negatively impacted gross margin by approximately $35 million for the quarter. The company also indicated that some level of unplanned outages can be expected in the business. - more - (TEXAS GENCO LETTERHEAD) FOR IMMEDIATE RELEASE Page 2 of 2 - -------------------------------------------------------------------------------- For the nine months ended September 30, 2003, income before cumulative effect of accounting change was $105 million, or $1.31 per share, compared to a loss of $50 million, or $0.62 per share for the same period of 2002.
