Item 2.02Results of Operations and Financial Condition

The Southern Company (“Southern Company”) and Mississippi Power Company (“Mississippi Power”) are furnishing this Current Report on Form 8-K to provide investors with information regarding Mississippi Power's updated cost estimates for completing the integrated gasification combined cycle project in Kemper County, Mississippi (the “Kemper IGCC”) and the related recognition of charges to income. The information set forth below in Item 7.01 is incorporated by reference into this Item 2.02.

Item 7.01Regulation FD Disclosure

See MANAGEMENT'S DISCUSSION AND ANALYSIS - FUTURE EARNINGS POTENTIAL - “Integrated Coal Gasification Combined Cycle” of Mississippi Power in Item 7 of the Annual Report on Form 10-K for the fiscal year ended December 31, 2012 (the “Form 10-K”) and Note 3 to the financial statements of Southern Company and Mississippi Power under “Integrated Coal Gasification Combined Cycle” in Item 8 of each company's Form 10-K for additional information regarding the construction of the Kemper IGCC and the proposed sale of a 15% undivided interest in the Kemper IGCC to the South Mississippi Electric Power Association (“SMEPA”).

Mississippi Power is constructing the Kemper IGCC which will utilize an integrated coal gasification combined cycle technology with an output capacity of 582 megawatts. The certificated cost estimate of the Kemper IGCC included in the order issued by the Mississippi Public Service Commission (the “Mississippi PSC”) in April 2012 confirming the issuance of the Certificate of Public Convenience and Necessity (the “CPCN”) for the Kemper IGCC (the “2012 MPSC Order”) was $2.4 billion, net of $245 million of Department of Energy (“DOE”) grants and the cost of the lignite mine and equipment, the cost of the carbon dioxide (“CO₂”) pipeline facilities, and allowance for funds used during construction (“AFUDC”) related to the Kemper IGCC. The 2012 MPSC Order approved a construction cost cap of up to $2.88 billion, with recovery of prudently-incurred costs subject to approval by the Mississippi PSC. Exceptions from the cost cap included in the 2012 MPSC Order include the cost of the lignite mine and equipment, the cost of the CO₂ pipeline facilities, AFUDC, and certain general exceptions, including change of law, force majeure, and beneficial capital (which exists when Mississippi Power demonstrates that the purpose and effect of the construction cost increase is to produce efficiencies that will result in a neutral or favorable effect on the ratepayers, relative to the provisions of the CPCN) (the “Cost Cap Exceptions”). Recovery of the Cost Cap Exception amounts remains subject to review and approval by the Mississippi PSC.

On January 24, 2013, Mississippi Power entered into a settlement agreement (the “Settlement Agreement”) with the Mississippi PSC that, among other things, establishes the process for resolving matters regarding cost recovery related to the Kemper IGCC. Under the Settlement Agreement, Mississippi Power agreed to limit the portion of prudently-incurred Kemper IGCC costs to be included in retail rate base to the $2.4 billion certificated cost estimate, plus the Cost Cap Exceptions as well as any other costs permitted or determined to be excluded from the cost cap by the Mississippi PSC. As contemplated by the Settlement Agreement, Mississippi Power intends to finance (1) prudently-incurred

costs in excess of the certificated cost estimate and up to the $2.88 billion cost cap and (2) the accrued AFUDC through securitization as provided in State of Mississippi legislation.

On April 23, 2013, Mississippi Power revised its cost estimate for the Kemper IGCC from approximately $2.88 billion, net of DOE grants and the Cost Cap Exceptions, to approximately $3.42 billion, net of DOE grants and the Cost Cap Exceptions. The revised cost estimate reflects additional cost pressures, including labor costs, piping and other material costs, engineering and support costs, and productivity decreases. Mississippi Power does not intend to seek any joint owner contributions or rate recovery for any costs of the Kemper IGCC that exceed the $2.88 billion cost cap, except for amounts subject to the Cost Cap Exceptions. Accordingly, Mississippi Power and Southern Company will reflect a pre-tax charge to income for this estimated probable loss of $540 million ($333 million after tax) in their first quarter 2013 financial statements.

The revised construction cost estimate reflects Southern Company's and Mississippi Power's current analysis of the costs to complete the Kemper IGCC and the related recognition of charges to income. Southern Company's and Mississippi Power's analysis will be ongoing throughout the construction period. It is possible that Mississippi Power could experience further cost increases and/or schedule delays with respect to the Kemper IGCC as a result of factors including, but not limited to, costs and productivity of labor, adverse weather conditions, shortages and inconsistent quality of equipment, materials, and labor, contractor or supplier delay or non-performance under construction or other agreements, delays associated with start-up activities, and/or unforeseen engineering problems. To the extent that it becomes probable that additional costs will not be recoverable, Mississippi Power and Southern Company would have additional charges to income, and such charges could be material.

The ultimate outcome of this matter cannot be determined at this time.
