NRG Energy, Inc. (NYSE: NRG) and GenOn Energy, Inc. (NYSE: GEN) today announced that the stockholders of both companies approved by substantial majorities the previously announced merger of the companies at their respective special meetings. "Today’s overwhelming shareholder vote in favor of the NRG/GenOn combination reflects the reality that this transaction is a clear win-win for everyone who owns a stake in either company,” said David Crane, president and CEO of NRG. “With this important milestone completed, we will continue our intense focus on completing the merger, executing on the synergies and creating the first truly 21st century energy company for the benefit of our customers and our shareholders.” “We look forward to the prompt receipt of the remaining approvals so that the stakeholders of the combined company can begin realizing the substantial cost savings and efficiency benefits associated with the merger,” said Edward R. Muller, chairman and CEO of GenOn. When completed, the combination of NRG and GenOn will create the nation’s largest competitive generator of electricity, with about 47,000 megawatts of generating capacity. The combined company’s diverse portfolio of fossil, solar, nuclear and wind facilities can support more than 37 million homes. Previously, the Federal Trade Commission had granted early termination of the Hart-Scott-Rodino waiting period, the Public Utility Commission of Texas had approved the transaction and the Nuclear Regulatory Commission had made a threshold determination that its approval of transaction was not required. The merger remains subject to the satisfaction or waiver of other closing conditions, including regulatory approvals by the Federal Energy Regulatory Commission and the New York Public Service Commission. The merger is expected to close by the first quarter of 2013. About NRG NRG is at the forefront of changing how people think about and use energy.
