Energy Future Holdings Reports Fourth Quarter and Full Year 2009 Results

DALLAS – February 19, 2010 – Energy Future Holdings Corp. (EFH) today reported consolidated financial results for the fourth quarter and year ended December 31, 2009. The full year results were reported in the company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) this morning.

“We had solid operational and record safety performance in 2009 and completed the construction of our new Sandow 5 and Oak Grove 1 coal units on time and on budget,” said John Young, CEO, Energy Future Holdings. “While the economic environment remains challenging, I believe Texas is positioned for future growth.”

Fourth Quarter GAAP Results

For the fourth quarter 2009, EFH reported consolidated net income attributable to EFH Corp. (in accordance with GAAP) of $137 million compared to a reported net loss of $8.855 billion for the fourth quarter 2008. The fourth quarter 2009 reported net income included (all after tax) $330 million in unrealized commodity-related mark-to-market net gains largely related to positions in EFH’s long-term hedging program (discussed further below), $110 million in unrealized mark-to-market net gains on interest rate swaps entered into to hedge interest expense, a $56 million debt extinguishment gain resulting from a fourth quarter 2009 debt exchange and a $14 million reversal of an outsourcing transition liability recorded in purchase accounting due to a shorter than planned transition period. These items were partially offset by a noncash impairment charge of $22 million for the carrying value of land expected to be sold in 2010.

The fourth quarter 2008 reported net loss included (all after tax) noncash impairment charges of $8.860 billion to write down goodwill, $310 million to write down the trade name intangible asset and $147 million to write down the carrying value of the natural gas-fueled generation plants, and $983 million in unrealized mark-to-market net losses on interest rate swaps. These items were partially offset by $1.642 billion (after tax) in unrealized mark-to-market net gains related to commodity positions.

Fourth Quarter Adjusted (Non-GAAP) Operating Results

Adjusted (non-GAAP) operating results for the fourth quarter 2009 totaled a net loss of $351 million compared to a net loss of $367 million for the fourth quarter 2008. For a reconciliation of reported GAAP results to adjusted (non-GAAP) operating results for the fourth quarter 2009 and 2008, see Tables A1 and A2.

Fourth quarter 2009 results from the competitive business improved $39 million (after tax) as compared to fourth quarter 2008. The increase reflected (all after tax) an $87 million improvement in contribution margin driven by favorable results from asset management and the retail business, the output from the new generation units, lower amortization of intangible assets arising from purchase accounting and lower purchased power costs during unplanned plant outages. Adding to the increase in contribution margin was an $18 million improvement in the effective income tax rate due to lower interest rates applied to uncertain tax positions. Offsetting factors included a $22 million increase in depreciation reflecting the placement in service of the Sandow 5 and Oak Grove 1 lignite-fueled generation units and related mining assets and ongoing investment in the generation fleet, an $11 million increase in interest expense

primarily due to lower capitalized interest and an $11 million reduction in other income due to insurance proceeds received in 2008 related to a mining equipment claim. Other offsetting factors included an $8 million increase in operating costs due to the new generation units, an $8 million increase related to marketing and employee related expenses, a $6 million increase in amortization of retail intangible assets arising from purchase accounting and a $4 million increase in retail bad debt expense.

Fourth quarter 2009 results related to the regulated business declined $23 million (after tax) as compared to fourth quarter 2008, including a $1 million decrease in net income attributable to Oncor noncontrolling interests arising from the November 2008 sale of a 20% interest. The $24 million after-tax decrease in earnings of the regulated business reflected (all after tax) $31 million in higher costs reflecting amortization of regulatory assets (primarily costs related to storm recovery and retirement benefits) approved for rate recovery, expenses associated with advanced meters and higher transmission fees and $19 million in higher depreciation reflecting infrastructure investment and higher depreciation rates. The higher amortization and depreciation resulted from findings in Oncor’s September 2009 final rate order. These cost increases were partially offset by $26 million in higher revenues driven by rate increases including tariffs approved in the September 2009 rate order.

Full Year GAAP Results

For the twelve months ended (full year) December 31, 2009, EFH reported consolidated net income attributable to EFH Corp. (in accordance with GAAP) of $344 million compared to a reported consolidated net loss of $9.838 billion for the full year 2008. The full year 2009 reported net income included (all after tax) $788 million in unrealized mark-to-market net gains related to commodity positions, $452 million in unrealized mark-to-market net gains on interest rate swaps and the $56 million debt extinguishment gain resulting from the fourth quarter 2009 debt exchange. These items were partially offset by noncash impairment charges of $90 million to finalize the estimated goodwill charge recorded in 2008 and $22 million related to the land value write down.

The full year 2008 reported net loss included (all after tax) the fourth quarter goodwill, trade name and natural gas-fueled generation plants impairment charges discussed above, $322 million for the impairment of sulfur dioxide and nitrogen oxide emissions allowances and $960 million in unrealized mark-to-market net losses on interest rate swaps, partially offset by $1.5 billion in unrealized mark-to-market net gains related to commodity positions.

Full Year Adjusted (Non-GAAP) Operating Results

Adjusted (non-GAAP) operating results for the full year 2009 totaled a net loss of $852 million compared to a net loss of $876 million for the full year 2008. For a reconciliation of reported GAAP results to adjusted (non-GAAP) operating results for full year 2009 and 2008, see Tables A3 and A4.

Full year 2009 results from the competitive business improved $121 million (after tax) as compared to full year 2008. The increase reflected (all after tax) a $287 million improvement in contribution margin driven by favorable results from asset management and the retail business, lower purchased power costs during unplanned plant outages, lower amortization of intangible assets arising from purchase accounting, higher output from the nuclear-fueled generation units driven by the effect of two nuclear unit refueling outages in 2008 versus one in 2009, the output from the new generation units and the effect on the retail business of Hurricane Ike in 2008. Offsetting factors included $66 million in higher net interest expense driven by increased amortization of interest rate hedge losses, a $32 million increase in costs related to the transition of outsourced services and the new retail customer care system, a $26 million increase in depreciation reflecting the new lignite-fueled generation facilities and ongoing investment in the generation fleet, $25 million in higher amortization of retail intangible assets arising from purchase accounting, $23 million in higher retail bad debt expense due to customer losses, new system conversion and general economic conditions and $18 million in higher operating costs related to the new generation units.

Full year 2009 results related to the regulated business declined $97 million (after tax) as compared to full year 2008, including a $53 million increase in net income attributable to the 20% Oncor noncontrolling interests. The $44 million after-tax decrease in earnings of the regulated business reflected (all after tax) $71 million in higher costs reflecting higher transmission fees, amortization of regulatory assets approved for rate recovery and expenses associated with advanced meters and $42 million in higher depreciation driven by infrastructure investment. The higher amortization and depreciation was based on Oncor’s September 2009 final rate order. Partially offsetting these cost increases was $71 million in higher revenues driven by rate increases including tariffs approved in the September 2009 rate order.

Long-Term Hedging Program

The EFH long-term hedging program is designed to reduce exposure to changes in future electricity prices due to changes in the price of natural gas. Under the program, subsidiaries of EFH have entered into market transactions involving natural gas-related financial instruments. As of December 31, 2009, these subsidiaries have sold forward approximately 1.6 billion MMBtu of natural gas (equivalent to the natural gas exposure of approximately 200,000 GWh at an assumed 8.0 market heat rate) for the period January 1, 2010 through December 31, 2014 at weighted average annual hedge prices ranging from $7.80 per MMBtu to $7.19 per MMBtu. These forward natural gas sales include related put and call transactions (referred to as collars), primarily for year 2014 of the program, that effectively hedge natural gas prices within a range. Collars represented approximately 6% of the positions in the long-term hedging program at December 31, 2009, with the approximate weighted average strike prices under the collars being a floor of $7.80 per MMBtu and a ceiling of $11.75 per MMBtu. For the period beginning January 1, 2010 and ending December 31, 2014, and taking into consideration the estimated portfolio impacts of forward retail and wholesale power sales, the hedging transactions result in EFH having effectively hedged an estimated 68% of the natural gas price exposure related to its expected generation output for such period (on an average basis for such period and assuming an 8.0 market heat rate).

Based on the size of the long-term hedging program as of December 31, 2009, a $1.00/MMBtu change in natural gas prices across the hedged period would result in the recognition by EFH of up to approximately $1.6 billion in pretax unrealized mark-to-market gains or losses. The effects of changes in forward natural gas prices on the values of positions in the program are reflected in net income (GAAP) as discussed above. Reported unrealized mark-to-market net gains (pretax) associated with the long-term hedging program totaled $548 million and $1.107 billion for fourth quarter and full year 2009, respectively, reflecting declines in forward natural gas prices. Given the volatility of natural gas prices, it is not possible to predict future reported unrealized mark-to-market net gains or losses and the actual net gains or losses that will ultimately be realized upon settlement of the hedge positions in future years. If natural gas prices at settlement are lower than the prices of the hedge positions, the hedges are expected to mitigate the otherwise negative effect on earnings of lower wholesale electricity prices. However, if natural gas prices at settlement are higher than the prices of the hedge positions, the hedges are expected to dampen the otherwise positive effect on earnings of higher wholesale electricity prices and will in this context be viewed as having resulted in an opportunity cost. The cumulative unrealized mark-to-market net gain (pretax) related to positions in the long-term hedging program totaled $871 million and $1.978 billion at December 31, 2008 and 2009, respectively.

Forward Looking Statements

This release contains forward-looking statements, which are subject to various risks and uncertainties. Discussion of risks and uncertainties that could cause actual results to differ materially from management’s current projections, forecasts, estimates and expectations is contained in EFH’s filings with the SEC. In addition to the risks and uncertainties set forth in EFH’s SEC filings, the forward-looking statements in this release regarding the company’s long-term hedging program could be affected by, among other things: any change in the ERCOT electricity market, including a regulatory or legislative change, that results in wholesale electricity prices not being largely correlated to natural gas prices; any decrease in market heat rates as EFH’s long-term hedging program generally does not mitigate exposure to changes in market heat rates; the unwillingness or failure of any hedge counterparty or the lender under the company’s collateral revolving credit facility to perform its obligations; or any other unforeseen event that results in the inability to continue to use a first lien to secure a substantial portion of the hedges under EFH’s long-term hedging program.
