Item 8.01 Other Events.

On February 25, 2020, Mississippi Power Company (“Mississippi Power”) and the Mississippi Public Utilities Staff (together with Mississippi Power, the “Stipulating Parties”) reached a settlement agreement (the “Mississippi Power Rate Case Settlement Agreement”) in Mississippi Power’s base rate case filed with the Mississippi Public Service Commission (“PSC”) on November 26, 2019. Under the terms of the Mississippi Power Rate Case Settlement Agreement, annual retail rates would decrease by approximately $16.7 million, or 1.85%, based on a test year period of January 1, 2020 through December 31, 2020, a 53% average equity ratio, an allowed maximum actual equity ratio of 55% by the end of 2020 and a 7.57% return on investment. The terms of the Mississippi Power Rate Case Settlement Agreement also: (1) established common amortization periods of four years for regulatory assets and three years for regulatory liabilities included in the proposed revenue requirement, including those related to unprotected deferred income taxes; (2) stipulated to new depreciation rates and to the reasonableness of those rates reflecting an annual increase in depreciation of approximately $10 million; and (3) excluded certain compensation costs totaling approximately $3.9 million, consistent with Mississippi Power’s original filing. Additionally, under the terms of the Mississippi Power Rate Case Settlement Agreement, separate rates for costs associated with Plant Ratcliffe (formerly known as the Kemper County energy facility) and energy efficiency initiatives would be eliminated and such costs would be included in the Performance Evaluation Plan (“PEP”), Environmental Compliance Overview Plan and Ad Valorem Tax Adjustment factor, as applicable.

The Mississippi Power Rate Case Settlement Agreement is subject to the approval of the Mississippi PSC. If approved, the rates set forth in the Mississippi Power Rate Case Settlement Agreement would become effective as soon as practicable following approval.

Additionally, Mississippi Power would be required to file with the Mississippi PSC PEP compliance rate clauses to incorporate the Stipulating Parties’ recommended revisions to PEP within 60

days following Mississippi PSC approval of the Mississippi Power Rate Case Settlement Agreement. These revisions include, but are not limited to, changing the filing date for the annual PEP rate filing from November of the immediately preceding regulatory year to March of the current regulatory year, utilizing a historic test year adjusted for “known and measurable” changes, using discounted cash flow and regression formulas to determine base return on equity and moving all embedded ad valorem property taxes currently collected in PEP to the Ad Valorem Tax Adjustment clause.

The ultimate outcome of these matters cannot be determined at this time.
