Adjusted earnings drivers for the full year 2024, as compared with 2023, were higher utility revenues, partially offset by increased non-fuel operations and maintenance expenses, interest expense, depreciation and amortization, and income taxes.

Fourth-quarter 2024 operating revenues were $6.3 billion, compared with $6.0 billion for the fourth quarter of 2023, an increase of 4.9%. Operating revenues for the full year 2024 were $26.7 billion, compared with $25.3 billion in 2023, an increase of 5.8%.

(2)Earnings for the twelve months ended December 31, 2024 include a pre-tax credit to income of $21 million ($16 million after tax) related to the estimated probable loss on Plant Vogtle Units 3 and 4 reflecting a revision to Georgia Power Company's total project capital cost forecast resulting from a reduction in remaining expected site demobilization costs and other contractor obligations. Additionally, earnings for the twelve months ended December 31, 2024 include a $14 million income tax charge related to the remeasuring of deferred tax assets associated with the previously recognized estimated probable loss on Plant Vogtle Units 3 and 4 due to a change in the State of Georgia corporate tax rate. Earnings for the three and twelve months ended December 31, 2023 include a pre-tax credit to income of $228 million ($170 million after tax) and a pre-tax net credit to income of $68 million ($50 million after tax), respectively, related to the estimated probable loss on Plant Vogtle Units 3 and 4. Further charges and/or credits may occur; however, the amount and timing are uncertain. Earnings for the three and twelve months ended December 31, 2024 and 2023 also include charges (net of salvage proceeds), associated legal expenses (net of insurance recoveries), and tax impacts related to Mississippi Power Company's integrated coal gasification combined cycle facility project in Kemper County, Mississippi. Mississippi Power Company expects to incur additional pre-tax period costs related to dismantlement of the abandoned gasifier-related assets and site restoration activities, including related costs for compliance and safety, asset retirement obligation accretion, and property taxes, net of salvage, totaling approximately $15 million in 2025.

(3)Earnings for the three and twelve months ended December 31, 2023 include a $35 million favorable tax impact related to a reversal of an uncertain tax position associated with the 2019 sale of Gulf Power Company. Additionally, earnings for the three and twelve months ended December 31, 2023 include disposition impacts related to the sales of natural gas storage facilities at Southern Company Gas. Further impacts may result from future acquisition and disposition activities; however, the amount and timing of any such impacts are uncertain.

(4)Earnings for the twelve months ended December 31, 2023 include costs associated with the extinguishment of debt at Southern Company. Similar transaction costs may occur in the future at Southern Company or one of its unregulated subsidiaries; however, the amount and timing of any such costs are uncertain.

(5)Earnings for the three and twelve months ended December 31, 2023 include a pre-tax charge of $58 million ($44 million after tax) and pre-tax charges totaling $96 million ($72 million after tax), respectively, for estimated losses at Southern Company Gas associated with the Illinois Commerce Commission disallowances related to (1) its review of the Qualifying Infrastructure Plant (QIP) capital investments by Nicor Gas under the QIP rider, or Investing in Illinois program and (2) Nicor Gas' general base rate case proceeding. Further charges may occur; however, the amount and timing of any such charges are uncertain.

(6)Earnings for the twelve months ended December 31, 2024 include a pre-tax impairment loss of $36 million ($27 million after tax) associated with the discontinued development of a multi-use commercial facility at Alabama Power Company. Impairment charges may occur in the future; however, the amount and timing of any such charges are uncertain.

(7)Earnings for the three and twelve months ended December 31, 2024 include a pre-tax charge, net of noncontrolling interests impacts, of $9 million ($7 million after tax) associated with accelerated depreciation related to the repowering of the Kay Wind facility at Southern Power.

EPS Earnings Analysis

Notes

(1)Excludes gains/losses on asset sales, which are included in "Interest Expense and Other." Includes non-service cost-related benefits income.

(2)Earnings for the twelve months ended December 31, 2024 include a pre-tax credit to income of $21 million ($16 million after tax) related to the estimated probable loss on Plant Vogtle Units 3 and 4 reflecting a revision to Georgia Power Company's total project capital cost forecast resulting from a reduction in remaining expected site demobilization costs and other contractor obligations. Additionally, earnings for the twelve months ended December 31, 2024 include a $14 million income tax charge related to the remeasuring of deferred tax assets associated with the previously recognized estimated probable loss on Plant Vogtle Units 3 and 4 due to a change in the State of Georgia corporate tax rate. Earnings for the three and twelve months ended December 31, 2023 include a pre-tax credit to income of $228 million ($170 million after tax) and a pre-tax net credit to income of $68 million ($50 million after tax), respectively, related to the estimated probable loss on Plant Vogtle Units 3 and 4. Further charges and/or credits may occur; however, the amount and timing are uncertain. Earnings for the three and twelve months ended December 31, 2024 and 2023 also include charges (net of salvage proceeds), associated legal expenses (net of insurance recoveries), and tax impacts related to Mississippi Power Company's integrated coal gasification combined cycle facility project in Kemper County, Mississippi. Mississippi Power Company expects to incur additional pre-tax period costs related to dismantlement of the abandoned gasifier-related assets and site restoration activities, including related costs for compliance and safety, asset retirement obligation accretion, and property taxes, net of salvage, totaling approximately $15 million in 2025.

(3)Earnings for the three and twelve months ended December 31, 2023 include a $35 million favorable tax impact related to a reversal of an uncertain tax position associated with the 2019 sale of Gulf Power Company. Additionally, earnings for the three and twelve months ended December 31, 2023 include disposition impacts related to the sales of natural gas storage facilities at Southern Company Gas. Further impacts may result from future acquisition and disposition activities; however, the amount and timing of any such impacts are uncertain.

(4)Earnings for the twelve months ended December 31, 2023 include costs associated with the extinguishment of debt at Southern Company. Similar transaction costs may occur in the future at Southern Company or one of its unregulated subsidiaries; however, the amount and timing of any such costs are uncertain.

(5)Earnings for the three and twelve months ended December 31, 2023 include a pre-tax charge of $58 million ($44 million after tax) and pre-tax charges totaling $96 million ($72 million after tax), respectively, for estimated losses at Southern Company Gas associated with the Illinois Commerce Commission disallowances related to (1) its review of the Qualifying Infrastructure Plant (QIP) capital investments by Nicor Gas under the QIP rider, or Investing in Illinois program and (2) Nicor Gas' general base rate case proceeding. Further charges may occur; however, the amount and timing of any such charges are uncertain.

(6)Earnings for the twelve months ended December 31, 2024 include a pre-tax impairment loss of $36 million ($27 million after tax) associated with the discontinued development of a multi-use commercial facility at Alabama Power Company. Impairment charges may occur in the future; however, the amount and timing of any such charges are uncertain.

(7)Earnings for the three and twelve months ended December 31, 2024 include a pre-tax charge, net of noncontrolling interests impacts, of $9 million ($7 million after tax) associated with accelerated depreciation related to the repowering of the Kay Wind facility at Southern Power. Accelerated depreciation related to the equipment being replaced will continue until commercial operation of the repowering project, which is projected to occur in the third quarter 2026. Pre-tax accelerated depreciation, net of noncontrolling interest impacts, is projected to total approximately $100 million in 2025 and $40 million in 2026.
