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

Third-quarter 2024 operating revenues were $7.3 billion, compared with $7.0 billion for the third quarter of 2023, an increase of 4.2%. For the nine months ended September 30, 2024, operating revenues were $20.4 billion, compared with $19.2 billion for the corresponding period in 2023, an increase of 6.1%.

“Our entire company, including our premier, state-regulated electric and gas utilities, continued to perform well during the third quarter,” said Christopher C. Womack, chairman, president and CEO.

“Employees across the Southern Company system came together in response to Hurricane Helene, a storm of exceptional magnitude which proved to be the most destructive in Georgia Power’s history,” added Womack. “We are thankful for the thousands of lineworkers, technicians and support staff who joined first responders, emergency management agencies and officials from the local, state and federal government, industry partners and an extraordinary mutual assistance workforce with tireless dedication to restore service to customers across Georgia. We are proud to continue to provide additional assistance to the individuals and families impacted by this devastating storm through contributions to aid organizations and other support. Our commitment to communities and customers has never been more important.”

Southern Company’s third-quarter earnings slides with supplemental financial information are available at investor.southerncompany.com.

Tucker will discuss earnings and provide a general business update.

(1)Dilution is not material in any period presented. Diluted earnings per share was $1.39 and $3.51 for the three and nine months ended September 30, 2024, respectively, and $1.29 and $2.84 for the three and nine months ended September 30, 2023, respectively.

(2)Earnings for the nine months ended September 30, 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 nine months ended September 30, 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 nine months ended September 30, 2023 include a pre-tax charge of $160 million ($120 million after tax) 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 nine months ended September 30, 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 to complete 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 annually through 2025.

(3)Earnings for the three and nine months ended September 30, 2023 include a pre-tax loss of $2 million ($1 million after tax) related to the sale of a natural gas storage facility at Southern Company Gas.

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 nine months ended September 30, 2023 include a pre-tax charge of $38 million ($28 million after tax) for an estimated loss at Southern Company Gas associated with an Illinois Commerce Commission disallowance related to its review of the Qualifying Infrastructure Plant (QIP) capital investments by Nicor Gas for calendar year 2019 under the QIP Rider, or Investing in Illinois program. Further charges may occur; however, the amount and timing of any such charges are uncertain.

(6)Earnings for the three and nine months ended September 30, 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.
