Use of Non-GAAP Financial Measures

Exhibit 99 to this Current Report on Form 8-K includes earnings and earnings per share in accordance with generally accepted accounting principles (“GAAP”) for the three-month and twelve-month periods ended December 31, 2025 and 2024. The exhibit also includes earnings and earnings per share (1) for the three-month and twelve-month periods ended December 31, 2025 and 2024, excluding (a) charges (net of salvage proceeds) and credits, associated legal expenses (net of insurance recoveries), and tax impacts related to plants under construction and (b) accelerated depreciation related to the repowering of certain wind facilities at Southern Power Company, (2) for the three-month and twelve-month periods ended December 31, 2025, excluding (a) costs associated with the extinguishment of debt at Southern Company, (b) an estimated loss at Southern Company Gas related to Nicor Gas capital investment disallowances by the Illinois Commerce Commission, and (c) a tax benefit related to an adjustment to the 2017 Tax Cuts and Jobs Act impact on certain deferred income tax balances at Southern Company Gas, (3) for the twelve-month period ended December 31, 2025, excluding disposition impacts related to the sale of a multi-use commercial facility development at Alabama Power

The attached exhibit includes additional information regarding these excluded items, as well as reconciliations of each non-GAAP financial measure to the most comparable financial measure under GAAP.

The presentation of this additional information is not meant to be considered a substitute for financial measures prepared in accordance with GAAP.

Adjusted earnings drivers for the full year 2025, as compared with 2024, were higher utility revenues, partially offset by higher non-fuel operations and maintenance expenses, depreciation and amortization, and interest expense.

Fourth-quarter 2025 operating revenues were $7.0 billion, compared with $6.3 billion for the fourth quarter of 2024, an increase of 10.1%. Operating revenues for the full year 2025 were $29.6 billion, compared with $26.7 billion in 2024, an increase of 10.6%.

“2025 was another outstanding year for Southern Company, and it was also a transformative one. Southern Company is meeting the growing demand responsibly, while continuing to deliver value and benefits to all of our customers,” said Chris Womack, chairman, president and CEO. “Taking a disciplined, all-of-the-above approach is how we will continue to operate our company to serve this projected generational growth in a way that supports rate stability and helps drive long-term savings for our customers.

performance of counterparties under ongoing renewable energy partnerships and development agreements; state and federal rate regulations and the impact of pending and future rate cases and negotiations, including rate actions relating to return on equity, equity ratios, additional generating capacity and transmission facilities, extension of retirement dates for fossil fuel plants, and fuel and other cost recovery mechanisms;

Notes

(1)Dilution is not material in any period presented. Diluted earnings per share was $0.38 and $3.92 for the three and twelve months ended December 31, 2025, respectively, and $0.48 and $3.99 for the three and twelve months ended December 31, 2024, respectively.

(2)Earnings include pre-tax credits to income of $27 million ($20 million after tax) and $60 million ($45 million after tax) for the three and twelve months ended December 31, 2025, respectively, and $21 million ($16 million after tax) for the twelve months ended December 31, 2024 related to the estimated probable loss on Plant Vogtle Units 3 and 4 reflecting reductions to Georgia Power Company's total project capital cost forecast, including the impact of joint owner cost-sharing. Site demobilization efforts were completed during the third quarter 2025 and remaining contractor obligations were finalized during the fourth quarter 2025. Additionally, earnings for the twelve months ended December 31, 2025 and 2024 include income tax charges of $4 million and $14 million, respectively, 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 changes in the State of Georgia corporate tax rate. Further charges related to the remeasuring of deferred tax assets may occur; however, the amount and timing are uncertain. Earnings for the three and twelve months ended December 31, 2025 and 2024 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. Dismantlement of the abandoned gasifier-related assets was completed at the end of 2025. Site restoration activities are substantially complete, and any additional costs are expected to be immaterial.

(3)Earnings include pre-tax charges, net of noncontrolling interests impacts, of $116 million ($90 million after tax) and $284 million ($221 million after tax) for the three and twelve months ended December 31, 2025, respectively, and $9 million ($7 million after tax) for the three and twelve months ended December 31, 2024 associated with accelerated depreciation related to the repowering of certain wind facilities at Southern Power Company. Accelerated depreciation related to the equipment being replaced will continue until the commercial operation dates of the repowering projects, which are projected to occur between the third quarter 2026 and the third quarter 2027. At December 31, 2025, the remaining pre-tax accelerated depreciation is projected to total approximately $490 million in 2026 and $100 million in 2027.

(4)Earnings for the three and twelve months ended December 31, 2025 include loss on extinguishment of debt totaling $123 million ($92 million after tax) and $252 million ($189 million after tax), respectively, as a result of Southern Company's repurchase of certain convertible senior notes. 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 twelve months ended December 31, 2025 include a pre-tax gain of $2 million ($1 million after tax) related to the sale of a multi-use commercial facility development at Alabama Power Company. Further impacts may result from future disposition activities; however, the amount and timing of any such impacts are uncertain. Earnings for the twelve months ended December 31, 2024 include a pre-tax impairment loss of $36 million ($27 million after tax) associated with Alabama Power Company discontinuing development of the multi-use commercial facility. Impairment charges may occur in the future; however, the amount and timing of any such charges are uncertain.

(6)Earnings for the three and twelve months ended December 31, 2025 include an estimated loss of $63 million ($47 million after tax) at Southern Company Gas related to Nicor Gas capital investment disallowances by the Illinois Commerce Commission. Further charges may occur; however, the amount and timing of any such charges are uncertain.

(7)Earnings for the three and twelve months ended December 31, 2025 include a tax benefit totaling $19 million at Southern Company Gas related to an adjustment to the 2017 Tax Cuts and Jobs Act impact on certain deferred income tax balances resulting from Internal Revenue Service private letter rulings. Additional adjustments are not expected.
