Adjusted earnings drivers for the second quarter of 2026, as compared with the same period in 2025, were investment in state-regulated utilities, customer usage and growth, higher earnings from equity method investments and lower income taxes, partially offset by higher interest expense.
Second-quarter 2026 operating revenues were $6.98 billion, compared with $6.97 billion for the second quarter of 2025, an increase of 0.1%. For the six months ended June 30, 2026, operating revenues were $15.4 billion, compared with $14.7 billion for the corresponding period in 2025, an increase of 4.2%.

Notes
(1)Dilution is not material in any period presented. Diluted earnings per share was $1.03 and $0.79 for the three and six months ended June 30, 2026, respectively, and $2.23 and $2.00 for the three and six months ended June 30, 2025, respectively.
(2)Earnings include pre-tax charges of $143 million ($111 million after tax) and $296 million ($230 million after tax) for the three and six months ended June 30, 2026, respectively, and $40 million ($31 million after tax, net of noncontrolling interest impacts) and $65 million ($51 million after tax, net of noncontrolling interest impacts) for the three and six months ended June 30, 2025, respectively, associated with accelerated depreciation and decommissioning costs related to the repowering of certain wind facilities at Southern Power Company. Accelerated depreciation and decommissioning costs associated with the replacement of equipment will continue until the completion dates of the repowering projects, which are projected to occur through the third quarter 2027. At June 30, 2026, the remaining pre-tax accelerated depreciation and decommissioning costs are projected to total approximately $205 million in 2026 and $120 million in 2027.
(3)Earnings include costs associated with the extinguishment of debt at Southern Company totaling $11 million ($8 million after tax) for the six months ended June 30, 2026, as a result of Southern Company's redemption of certain junior subordinated notes, and $129 million ($97 million after tax) for the three and six months ended June 30, 2025, 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.
(4)Earnings for the three and six months ended June 30, 2026 include an estimated loss of $8 million ($6 million after tax) and $10 million ($8 million after tax), respectively, at Southern Company Gas related to costs associated with Nicor Gas capital investments disallowed by the Illinois Commerce Commission in November 2025. Further charges may occur; however, the amount and timing of any such charges are uncertain.
(5)Earnings include income tax charges of $4 million for the three and six months ended June 30, 2026 and 2025 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 and/or credits may occur; however, the amount and timing are uncertain. Earnings for the three and six months ended June 30, 2025 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.
(6)Earnings for the three and six months ended June 30, 2026 include a state income tax refund of $9 million ($7 million after federal tax) at Southern Company Gas associated with the 2018 disposition of Elizabethtown Gas, partially offset by related contingency fee expenses of $2 million ($1 million after tax) incurred in connection with obtaining the refund. Additional income tax refunds related to past dispositions may occur in the future; however, the amount and timing are uncertain.

(1)Dilution is not material in any period presented. Diluted earnings per share was $1.03 and $0.79 for the three and six months ended June 30, 2026, respectively, and $2.23 and $2.00 for the three and six months ended June 30, 2025, respectively.
(2)Earnings include pre-tax charges of $143 million ($111 million after tax) and $296 million ($230 million after tax) for the three and six months ended June 30, 2026, respectively, and $40 million ($31 million after tax, net of noncontrolling interest impacts) and $65 million ($51 million after tax, net of noncontrolling interest impacts) for the three and six months ended June 30, 2025, respectively, associated with accelerated depreciation and decommissioning costs related to the repowering of certain wind facilities at Southern Power Company. Accelerated depreciation and decommissioning costs associated with the replacement of equipment will continue until the completion dates of the repowering projects, which are projected to occur through the third quarter 2027. At June 30, 2026, the remaining pre-tax accelerated depreciation and decommissioning costs are projected to total approximately $205 million in 2026 and $120 million in 2027.
(3)Earnings include costs associated with the extinguishment of debt at Southern Company totaling $11 million ($8 million after tax) for the six months ended June 30, 2026, as a result of Southern Company's redemption of certain junior subordinated notes, and $129 million ($97 million after tax) for the three and six months ended June 30, 2025, 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.
(4)Earnings for the three and six months ended June 30, 2026 include an estimated loss of $8 million ($6 million after tax) and $10 million ($8 million after tax), respectively, at Southern Company Gas related to costs associated with Nicor Gas capital investments disallowed by the Illinois Commerce Commission in November 2025. Further charges may occur; however, the amount and timing of any such charges are uncertain.
(5)Earnings include income tax charges of $4 million for the three and six months ended June 30, 2026 and 2025 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 and/or credits may occur; however, the amount and timing are uncertain. Earnings for the three and six months ended June 30, 2025 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.
(6)Earnings for the three and six months ended June 30, 2026 include a state income tax refund of $9 million ($7 million after federal tax) at Southern Company Gas associated with the 2018 disposition of Elizabethtown Gas, partially offset by related contingency fee expenses of $2 million ($1 million after tax) incurred in connection with obtaining the refund. Additional income tax refunds related to past dispositions may occur in the future; however, the amount and timing are uncertain.
