March 07, 2006 March 7, 2006 ROSEMEAD, Calif., March 7, 2006 — Edison International (EIX) recorded consolidated earnings per common share of $3.47 in 2005, compared to $2.81 in 2004. Higher wholesale energy margins and energy trading income at Mission Energy Holding Company (MEHC) were major earnings drivers in 2005. Reductions and refinancing of debt in 2004 and 2005 resulted in lower interest expense across the company. Core earnings per share of $3.13 in 2005 represented an increase of about 109% over prior year’s core earnings of $1.50 per share. Core earnings exclude earnings from discontinued operations and other non-core items. 2005 Financial Highlights: Core earnings per common share - $3.13 Net Income - $1.1 billion Revenue - $11.9 billion Assets - $34.8 billion YEAR 2005 EARNINGS SUMMARY For the year ending December 31, 2005, EIX recorded consolidated earnings of $1.1 billion compared to earnings of $916 million for the prior year. "2005 was a year of strong performance at our company,” said Chairman and CEO John Bryson. “Earnings increased 23% over the prior year, driven primarily by our unregulated businesses. We also fully met our ambitious investment goals to strengthen the distribution and transmission system for the benefit of our utility customers." Results for 2005 and 2004 included several non-core adjustments detailed in the tables presented in this release. YEAR 2005 EARNINGS DETAIL Earnings (Loss) from Continuing Operations Southern California Edison’s (SCE) earnings from continuing operations were $725 million in 2005, compared with $915 million in 2004. SCE’s 2005 earnings included positive items of $61 million related to a favorable tax settlement, $55 million from a favorable Federal Energy Regulatory Commission (FERC) decision on a SCE transmission proceeding and a $14 million incentive benefit from generator refunds related to the California energy crisis period. SCE’s 2004 earnings included $329 million of positive regulatory and tax items, primarily from implementation of the 2003 general rate case decision that was received in July 2004. Excluding these non-core items, core earnings were up $9 million due to higher net revenue, including tax benefits, and lower financing costs, partially offset by the impact of a lower authorized rate of return on common equity in 2005. MEHC’s income from continuing operations was $322 million in 2005, compared to a loss of $666 million in 2004. MEHC’s 2005 results include an impairment charge of $34 million related to the March Point project and a $15-million charge related to early debt retirements. MEHC’s 2004 results included a charge of $590 million for the termination of the Collins Station lease, a net gain of $27 million on the sale of its interest in Four Star Oil and Gas and the Brooklyn Navy Yard projects and a charge of $18 million related to a peaker impairment. Excluding these non-core items, MEHC’s core earnings increased by $456 million over 2004 to $371 million. This increase was primarily due to higher wholesale energy margins mainly driven by higher prices, higher energy trading income and lower net interest expense. Earnings in 2005 for Edison Capital were $91 million compared to $60 million in the same period last year. The increase primarily reflects higher income from Edison Capital’s investment in the Emerging Europe Infrastructure Fund. Excluding the 2004 charge related to the early debt retirements of $14 million, the loss for “EIX parent company and other” decreased by $39 million primarily due to lower net interest expense. Earnings from Discontinued Operations Earnings from discontinued operations during 2005 primarily reflect positive tax adjustments of $28 million resulting from the sales of international projects, a charge of $25 million related to a tax indemnity on an international project sold in 2004, $24 million in partial dividends from the Lakeland receivership, the sale of CBK and Tri-Energy earlier this year and other items. Earnings from discontinued operations during 2004, including a gain and recognition of a tax benefit, were $690 million.

The results included non-core adjustments detailed in the tables below. EIX’s core earnings were 71 cents per share for the three-month period ending December 31, 2005, compared to 35 cents per share for the same period last year. This increase primarily reflects higher wholesale energy margins mainly driven by higher prices, and higher energy trading income, at MEHC and lower net interest expense, partially offset by higher net operating costs at SCE in the fourth quarter. FOURTH-QUARTER EARNINGS DETAIL Earnings (Loss) from Continuing Operations SCE’s earnings from continuing operations for the quarter ended December 31, 2005, were $153 million compared to $315 million in the same period last year. SCE’s results for 2005 included a positive item of $55 million from a favorable FERC decision on SCE’s transmission proceeding and a $10 million incentive benefit from generator refunds related to the California energy crisis period. SCE’s quarterly results in the prior year included positive regulatory and tax items totaling $157 million. Excluding these items, SCE’s 2005 core earnings for the quarter were $88 million compared to $158 million in the same period last year. The decrease in earnings was primarily due to higher operating and tax expenses in the fourth quarter. MEHC had earnings from continuing operations and core earnings of $143 million for the quarter ended December 31, 2005, compared to a loss of $52 million in the same period last year. The increase primarily reflects higher wholesale energy margins driven by higher prices and higher energy trading income and lower net interest expense partially offset by lower generation and higher maintenance expenses at the Homer City plant. Edison Capital’s earnings for the quarter ended December 31, 2005, were $11 million compared to $26 million in the same period last year. This decrease was primarily due to gains recorded in 2004 from the Emerging Europe Infrastructure Fund. The loss for the quarter ended December 31, 2005, for “EIX parent company and other” decreased by $22 million compared to the same period last year due to the elimination of debt. Earnings from Discontinued Operations MEHC had a loss of $26 million from discontinued operations for the quarter ended December 31, 2005, reflecting a tax charge related to its previously owned international projects. Earnings from discontinued operations for the quarter ended December 31, 2004, were $120 million. The 2004 results for the quarter include a $65-million gain on the sale of the international assets that closed in 2004 and earnings from the discontinued international projects of $55 million.
