Item 8.01 Other Events.

On December 19, 2025, the Georgia Public Service Commission (“PSC”) voted to approve the settlement agreement between Georgia Power Company (“Georgia Power” or the “Company”) and the Georgia PSC Public Interest Advocacy Staff, which was filed with the Georgia PSC on December 9, 2025 (the “Settlement Agreement”). The Settlement Agreement resolves the Company’s Application for the Certification of Capacity from the 2029-2031 All-Source Request for Proposals and Application for the Certification of Supplemental Resources for 2028-2031 Capacity (collectively, the “All-Source Certification Proceeding”).

Under the terms of the Settlement Agreement, all 9,885 megawatts of requested resources in the All-Source Certification Proceeding have been approved and certified at their respective individual project cost. Included in these resources are the Company-owned projects totaling approximately $16.3 billion of projected capital investment, excluding allowance for funds used during construction, of which approximately $14 billion is expected to be incurred in 2026 through 2029. The Company-owned projects will require construction monitoring by the Georgia PSC.

The Company has agreed to file its next base rate case in a manner that will ensure the incremental revenue from large load customers has downward pressure (i.e., customer benefits), on a levelized basis, of at least $556 million per year, which is equivalent to $8.50 per month (or approximately $102 per year) to the typical residential customer using an average of 1,000 kilowatt-hours per month, for the years 2029, 2030 and 2031.

The reader is cautioned not to put undue reliance on this forward-looking information, which is not a guarantee of future performance and is subject to a number of uncertainties and other factors, many of which are outside the control of The Southern Company and Georgia Power; accordingly, there can be no assurance that such suggested results will be realized.
