Item 8.01 Other Events.

On May 19, 2025, Georgia Power Company (“Georgia Power”) and the Georgia Public Service Commission (“PSC”) Public Interest Advocacy Staff (collectively, the “Stipulating Parties”) reached a settlement agreement (“Settlement Agreement”) that, if approved by the Georgia PSC, would extend the alternate rate plan approved by the Georgia PSC, which set retail base rates for the years 2023 through 2025 (“2022 ARP”) for an additional three-year term through December 31, 2028. Under the terms of the Settlement Agreement, base rates would not be adjusted in 2026, 2027 or 2028 (“ARP Extension Period”) except for reasonable and prudent storm damage costs incurred through December 31, 2025, which would be determined in a separate regulatory proceeding.

Under the terms of the Settlement Agreement, Georgia Power’s retail return on common equity (“ROE”) set point would continue at 10.50% and its equity ratio would continue at 56%. Additionally, the retail ROE range approved by the Georgia PSC in the 2022 ARP, of 9.50% to 11.90%, would continue. The Settlement Agreement includes, among other things, the following modifications to the 2022 ARP:

1.Storm damage costs would be included in a separate regulatory proceeding to be filed no sooner than February 1, 2026 and no later than July 1, 2026 to recover the actual reasonable and prudent storm costs incurred through December 31, 2025. Subject to Georgia PSC approval, new rates would be effective approximately 90 days after the filing is made. The Georgia PSC would determine the period over which any such storm damage costs would be recovered.

2. Amortization of regulatory assets and liabilities in the 2022 ARP, which were subsequently included in current rates through annual compliance filings, would continue through the ARP Extension Period. This includes those regulatory asset and liability balances that were projected to be fully amortized through 2025 or during the ARP extension period.

3. The amounts previously deferred during the 2022 ARP for Investment Tax Credits (“ITCs”) and Production Tax Credits (“PTCs”) would be amortized through the ARP Extension Period.

The acceleration of amortization during the ARP Extension Period is subject to the Internal Revenue Code normalization rules and other guidance (if any) expected to be released by the Internal Revenue Service. Certain amounts of ITCs generated during the ARP Extension Period would be amortized to amortization expense over five years, and additional ITC amounts would be deferred to a regulatory liability during the ARP Extension Period. Sixty percent (60%) of PTC benefits generated (excluding PTCs generated under Internal Revenue Code §45J) during the ARP Extension Period would be credited to income tax expense as generated. The remaining forty percent (40%) would be deferred to a regulatory liability.

4. The period for depreciation and amortization related to certain generating plants and net book values of retired generating plants would be 13 years effective January 1, 2026.

Using the retail ROE range approved by the Georgia PSC in the 2022 ARP, earnings above the upper limit of the 9.50% to 11.90% retail ROE range would continue to be subject to sharing whereby 40% of earnings above the band would be applied to regulatory assets, 40% would be directly refunded to customers and the remaining 20% would be retained by Georgia Power. There would be no recovery of any earnings shortfall below the lower end of the approved retail ROE range on an actual basis. However, if at any time during the term of the ARP Extension Period, Georgia Power projects that its retail earnings will be less than the lower end of the approved retail ROE range for any calendar year of the ARP Extension Period, it may petition the Georgia PSC for implementation of the Interim Cost Recovery (“ICR”) tariff to adjust Georgia Power’s retail rates to achieve a retail ROE equal to the lower end of the approved retail ROE range. The ICR tariff would expire at the earlier of January 1, 2029 or the end of the calendar year in which the ICR tariff becomes effective. In lieu of requesting implementation of an ICR tariff, or if the Georgia PSC chooses not to implement the ICR tariff, Georgia Power may file a full base rate case. Georgia Power would be required to file a base rate case by July 1, 2028.

While the Stipulating Parties are seeking support of the Settlement Agreement from other parties, the Settlement Agreement must be approved by the Georgia PSC. Accordingly, the terms of the

Settlement Agreement are subject to change and the terms of any final agreement approved by the Georgia PSC may differ materially from the terms of the Settlement Agreement. The Georgia PSC is scheduled to vote on or before July 1, 2025 to resolve all matters in the Settlement Agreement. If the Settlement Agreement is not approved by the Georgia PSC, Georgia Power is required to file its next base rate case by July 1, 2025. The ultimate outcome of this matter cannot be determined at this time.
