EXHIBIT 99.1 FOR FURTHER INFORMATION: Sandy Fruhman, Media (713) 207-3123 Melanie Trent, Investors (713) 207-8351 FOR IMMEDIATE RELEASE: July 31, 2002 RELIANT RESOURCES AFFIRMS STRONG LIQUIDITY POSITION AND SOLID BUSINESS FUNDAMENTALS HOUSTON, TX. - Reliant Resources, Inc. (NYSE: RRI) reiterated its strong liquidity position and solid business fundamentals in light of Moody's decision to change the rating of the company's senior unsecured debt. "We are disappointed with the Moody's rating action today," said Steve Letbetter, chairman and chief executive officer. "While we are not surprised with a downgrade from Moody's in light of current industry conditions and the pressure on the rating agencies in the current corporate credit environment, we do not believe that the new rating is appropriate. The rating appears to reflect a sector approach that fails to recognize significant differences between Reliant Resources and others in our industry. "Our combination of a strong Texas retail position, hard assets, and ability to optimize those assets will continue to provide a solid foundation for the company and allow us to maintain our commitment to our customers, our shareholders and our employees," Letbetter added. "While we disagree with the rating, we recognize the company and the industry are under pressure. As we told investors during our earnings call last week, we have been taking the steps necessary to ensure that we can continue to run our business successfully. "We have stress-tested our business, and we have sufficient accessible liquidity to meet the financial needs brought on by the change in ratings," continued Letbetter. Additional liquidity requirements triggered by loss of investment grade status are estimated at approximately $650 million based on current commodity prices. The company has approximately $1.2 billion of cash and available lines of credit to meet its needs. Credit rating downgrades do not trigger any defaults under the company's or its parent's debt agreements. -more- "In addition, we do not anticipate that the downgrade changes our refinancing prospects with our lenders as we believe that they have also been anticipating the possibility of a downgrade of the company's senior unsecured rating. We continue to be confident in our bank refinancing prospects," said Letbetter. The company reiterated its earnings guidance for 2002 of a range of $1.65 to $1.85 per share and said the rating change does not affect its proposed spin-off from Reliant Energy, Incorporated (NYSE:REI).
