1 EXHIBIT 99.1 RELIANT ENERGY RESOURCES CORP. AND SUBSIDIARIES (A WHOLLY OWNED SUBSIDIARY OF RELIANT ENERGY, INCORPORATED) UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS The following unaudited pro forma condensed consolidated financial statements of Reliant Energy Resources Corp. and its subsidiaries for the year ended December 31, 1999 and as of and for the nine months ended September 30, 2000 have been prepared based upon Reliant Energy Resources Corp.'s (the Company) historical financial statements. The pro forma financial statements have been prepared to describe the effects of the transfer of a portion of the Company's unregulated businesses to subsidiaries of Reliant Resources, Inc. (Reliant Resources), a wholly owned subsidiary of Reliant Energy, Incorporated (Reliant Energy). On July 27, 2000, Reliant Energy announced its intention to divide into two publicly traded companies in order to separate its unregulated businesses from its regulated businesses. In August 2000, Reliant Energy formed Reliant Resources to own and operate a substantial portion of Reliant Energy's unregulated operations and to offer approximately 20% of Reliant Resources' common stock in an initial public offering (the Offering). Reliant Energy expects the Offering to be followed by a distribution to Reliant Energy's or its successor's shareholders of the remaining common stock of Reliant Resources within twelve months after the Offering. As a part of Reliant Energy's separation plan, on December 31, 2000, (a) the Company transferred all of the outstanding stock of Reliant Energy Services International, Inc., Arkla Finance Corporation and Reliant Energy Europe Trading & Marketing, Inc. to Reliant Resources (collectively, the Stock Transfer) and (b) a wholly owned subsidiary of Reliant Resources merged with and into Reliant Energy Services, Inc. (RES), a wholly owned subsidiary of the Company, with RES as the surviving corporation (the Merger). As a result of the Merger, RES became a wholly owned subsidiary of Reliant Resources. As consideration for the Merger, Reliant Resources paid $120 million to the Company, plus or minus, as the case may be, an amount equal to the difference of the working capital of RES on December 31, 2000 and August 31, 2000. The unaudited pro forma condensed consolidated financial statements do not purport to present the Company's actual results of operations as if the Stock Transfer and the Merger had occurred on January 1, 1999 for the unaudited pro forma condensed statements of operations or September 30, 2000 for the unaudited pro forma condensed balance sheet nor are they necessarily indicative of the Company's financial position or results of operations that may be achieved in the future. The unaudited pro forma condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 1999 and the Company's interim consolidated financial statements and related notes included in the Company's Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2000, each of which has been previously filed with the Securities and Exchange Commission. 2 RELIANT ENERGY RESOURCES CORP.
