Filed by Xcel Energy Inc. Pursuant to Rule 425 under the Securities Act of 1933 Subject Company: NRG Energy, Inc. NRG Energy, Inc.'s Commission File No. 001-15891 February 15, 2002 Minneapolis: Xcel Energy to tender for NRG Energy stock MINNEAPOLIS - Xcel Energy (NYSE: XEL) announced today that its board of directors approved plans to commence an exchange offer by which Xcel Energy would acquire all of the outstanding publicly held shares of its subsidiary, NRG Energy, Inc. (NYSE: NRG). Xcel Energy currently owns 74 percent of NRG. In the offer, NRG shareholders would receive 0.4846 shares of Xcel Energy common stock in a tax-free exchange for each outstanding share of NRG common stock. Based on Thursday's (Feb. 14) closing price, the offer represents a 15 percent premium. Additionally, following completion of the transaction, shareholders would be entitled to Xcel Energy's current annual dividend of $1.50 per share. "We are confident that our decision to acquire the public shares of NRG is in the best interests of both the NRG and Xcel Energy shareholders," said Wayne H. Brunetti, chairman, president and CEO of Xcel Energy. In 1989, NRG was developed as an independent power producer (IPP) to create additional shareholder value as a growth company. "NRG's management has grown the company rapidly, and today it is the third largest IPP worldwide with nearly 20,000 megawatts of power generation," Brunetti said. NRG completed public offerings in June 2000 and March 2001. "However, numerous factors have recently led to significant erosion in the valuations within the IPP sector and resulted in a fundamental shift in market perception that has increased the cost of capital for these companies," Brunetti said. "These events require a refocusing of NRG's current business model. The new focus of NRG will be on managed growth with a stronger balance sheet, cost management and reduced dependence on external financing." Brunetti said Xcel Energy's plans for NRG in 2002 include: o Infusing $600 million of equity into NRG o Selling approximately $1.9 billion of existing, largely international, generating assets o Canceling approximately $700 million of planned projects and deferring about $900 million of projects o Selling unassigned turbines, and o Reducing business development and A&G expenses by about $45 million. These actions are expected to reduce 2002 cash requirements by about $3 billion, Brunetti said. He noted that the company expects to capture other benefits, not included in the current projections, resulting from: o Consolidating trading and marketing organizations while honoring all regulatory requirements o Integrating power plant management across the Xcel Energy system, and o Capturing infrastructure savings, where appropriate, to maximize available synergies. "These actions demonstrate our commitment to an investment-grade bond rating for NRG and a high quality rating at Xcel Energy," Brunetti said. Xcel Energy Chief Financial Officer Jim McIntyre said the acquisition of NRG should add about 5 cents per share to Xcel Energy's 2002 earnings and about 10 cents per share in 2003 and beyond. "We plan to maintain Xcel Energy's earnings guidance for 2002 at $2.40 to $2.50 per share, and we expect the annual earnings per share growth to average 7 percent to 9 percent, with NRG's contribution growing about 15 percent per year," he said. "We view the annualized $1.50 per share dividend as a very important part of the Xcel Energy value proposition for investors. We are committed to maintaining that dividend even as we move to acquire the NRG minority shareholder interest," McIntyre added. Brunetti noted that this transaction supports Xcel Energy's "balanced portfolio" strategy and enhances the stability of its energy merchant business. Xcel Energy plans to begin the exchange offer as soon as practical. Completion of the offer will be conditioned upon NRG's public shareholders tendering enough shares so that, when taken together with the shares of common stock that Xcel Energy currently holds, Xcel Energy would own at least 90 percent of NRG's common stock. To satisfy this condition, which will not be waived, NRG shareholders must tender approximately 60 percent of the publicly held NRG shares currently outstanding. Upon successful completion of the exchange, Xcel Energy will merge NRG with a wholly owned subsidiary of Xcel Energy in a "short-form" merger. In the merger, each remaining share of NRG common stock will be exchanged (subject to the exercise of appraisal rights) for the same number of shares of Xcel Energy common stock as is exchanged in the exchange offer. Lehman Brothers is acting as Xcel Energy's financial advisor for the transaction. Xcel Energy will host a conference call and Web cast beginning at 8:00 a.m. Central Standard Time on Feb. 15.
