Edison International Reports First Quarter 2009 Earnings

ROSEMEAD, Calif., May 8, 2009 – Edison International (NYSE: EIX) today reported first quarter 2009 results.

First quarter 2009 GAAP earnings were $0.76 per share compared to $0.91 per share in the same quarter last year, reflecting significantly lower earnings at Edison Mission Group (EMG). Core earnings in the first quarter were $0.79 per share compared to $0.92 per share in the same quarter last year.

“Our first quarter results are consistent with our 2009 outlook. Looking forward, our ability to realize our growth potential rests on two key initiatives. At Southern California Edison, it is our five-year, approximately $20 billion, investment in California’s electricity infrastructure and at EMG, it is the development of a large pipeline of potential wind and solar energy projects,” said Theodore F. Craver, Jr., chairman and chief executive officer of Edison International.

First Quarter Earnings Detail

Southern California Edison Company’s (SCE) first-quarter 2009 GAAP and core earnings were $0.64 per share, compared to $0.46 per share in the same quarter of 2008. This increase was primarily due to SCE’s 2009 General Rate Case (GRC) decision in March, which was effective January 1, 2009, and expense timing differences arising from the delay in receiving the utility’s GRC decision.

EMG reported GAAP earnings of $0.14 per share in the first quarter of 2009 compared to $0.48 per share in the first quarter of 2008. Core earnings were $0.17 per share compared to $0.49 per share, excluding a $0.04 per share non-core charge in the first quarter of 2009 reflecting termination of two lease agreements at Edison Capital as well as discontinued operations. EMG earnings for the quarter decreased over the same quarter last year primarily due to a significant decline in Midwest Generation and Homer City results from lower power prices and generation levels as well as reduced trading income. Partially offsetting these decreases were higher earnings from the wind projects in operation. Results for the first quarter of 2008 also included the favorable buy-out of a coal contract at Midwest Generation.

2009 Earnings Guidance

Previously announced core earnings guidance of $2.90 - $3.20 per share is reaffirmed. The company has revised its 2009 GAAP earnings guidance to reflect expected recognition of certain non-core charges related to the company’s global settlement with the U.S. Internal Revenue Service, which was finalized in the second quarter of this year.

Risk Disclosure Statement and Financial Schedules

Use of Non-GAAP Financial Measures

Edison International’s earnings are prepared in accordance with generally accepted accounting principles used in the United States and represent the company’s earnings as reported to the Securities and Exchange Commission. Our management uses core earnings and EPS by principal operating subsidiary internally for financial planning and for analysis of performance. We also use core earnings and EPS by principal operating subsidiary as primary performance measurements when communicating with analysts and investors regarding our earnings results and outlook, as it allows us to more accurately compare the company’s ongoing performance across periods. Core earnings exclude discontinued operations and other non-core items and are reconciled to GAAP earnings.

Earnings per share (EPS) by principal operating subsidiary is based on the principal operating subsidiary net income attributable to the common shareholders of each operating susidiary, respectively, and Edison International’s weighted average outstanding common shares. The impact of participating securities (vested stock options that earn dividend equivalents that may participate in undistributed earnings with common stock) for each principal operating subsidiary is not material to each principal operating subsidiary’s EPS and is therefore reflected in the results of the Edison International holding company, which we refer to as EIX parent company and other. EPS and core EPS by principal operating subsidiary are reconciled to GAAP EPS.
