PHOENIX -- Power generator NRG Energy on Sunday rejected an unsolicited $6.1 billion all-stock bid from nuclear power giant and utility operator Exelon, calling the offer, which would create the largest U.S. power company, too low.
Princeton, New Jersey-based NRG Energy also said it rejected the proposal because Exelon has yet to line up the financing for the deal.
Chicago-based Exelon made the offer last month. It has said the combined Exelon and NRG would have been big enough to power nearly 45 million homes with 47,000 megawatts. It would have had a diverse power mix and a market capitalization of $40 billion.
"We could not be more certain in our belief that your proposal is opportunistic, serving only as a means for Exelon to extract a severely disproportionate percentage of the current and future value of NRG and its assets from its rightful owners, NRG's shareholders, and transfer it to Exelon and its shareholders," NRG President and Chief Executive David Crane and board Chairman Howard Cosgrove wrote in a letter to Exelon Chairman and Chief Executive John Rowe.
NRG said its shareholders would have ended up owning 17% of the combined company while contributing 30% of the merged company's free cash flow in 2008.
NRG accused Rowe of coming up with a "lowball exchange ratio" after Rowe met with company officials in September. NRG said it believes in industry consolidation and "always will be a willing seller or buy when genuine value can be created for both parties."
NRG also said its shareholders would have taken on additional financial risk with the deal, noting that NRG third-quarter results exceeded estimates while Exelon's results came in below expectations and that NRG's growth would be dragged down by Exelon's debt.
Crane said in an interview Sunday that Exelon is trying to take advantage of NRG while its share price is down so much because of the market turbulence. He said the company was surprised that Exelon made the offer without lining up financing in advance.
NRG remains open to discussing a deal. "It just has to have value for both sides," he said.
Exelon said Sunday night that it is reviewing the letter.
When the deal was announced last month, Rowe said Exelon was not prepared to make an offer when he met with Crane on Sept. 30 because of market turbulence.
"We hope this turns out to be friendly rather than hostile, but we are committed to pursuing this offer and we shall do so," he said then.
Under terms of the proposal, Exelon would have exchanged 0.485 Exelon shares for each NRG share. NRG shares that cost $43.95 on July 2 had fallen to $23.86 by Friday. Exelon shares closed at $53.82 on Friday, down from their 52-week high of $92.13 set July 7.
With the offer, Exelon was the second utility to try to capitalize on the credit crisis and global economic slowdown that have pounded the shares of utilities and power generators. A unit of Warren Buffett's Berkshire Hathaway Inc. is buying wholesale power generator Constellation Energy Group Inc. of Baltimore for the bargain price of $4.7 billion after analysts worried that the company might become insolvent.
Buyouts and attempted mergers have begun to accelerate just three years after the repeal of the Public Utility Holding Company Act of 1935, which strictly regulated utilities.
In May, Calpine Corp., operator of 60 power plants that can produce up 23,000 megawatts of electricity, rejected an unsolicited takeover bid from NRG as too low.
NRG has ownership interests in 44 power generating facilities, primarily in the U.S., that generate 24,000 megawatts of power.
Exelon has nearly $19 billion in annual revenue and 5.4 million electric customers in northern Illinois and Pennsylvania. It also has 480,000 natural gas customers in the Philadelphia area.
Its 10 nuclear stations, with 17 reactors, represent approximately 20% of the U.S. nuclear industry's power capacity, and about 3% of all U.S. power generation.
