NOTES TO THE CONDENSED FINANCIAL STATEMENTS

(UNAUDITED)

(A) INTRODUCTION

The condensed quarterly financial statements of each Registrant included herein have been prepared by such Registrant, without audit, pursuant to the rules and regulations of the SEC. The Condensed Balance Sheets as of December 31, 2019 have been derived from the audited financial statements of each Registrant. In the opinion of each Registrant's management, the information regarding such Registrant furnished herein reflects all adjustments, which, except as otherwise disclosed, are of a normal recurring nature, necessary to present fairly the results of operations for the periods ended June 30, 2020 and 2019. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations, although each Registrant believes that the disclosures regarding such Registrant are adequate to make the information presented not misleading. Disclosures which would substantially duplicate the disclosures in the Form 10-K and details which have not changed significantly in amount or composition since the filing of the Form 10-K are generally omitted from this Quarterly Report on Form 10-Q unless specifically required by GAAP. Therefore, these Condensed Financial Statements should be read in conjunction with the financial statements and the notes thereto included in the Form 10-K. Due to the seasonal variations in the demand for energy and other factors, including the impacts of the COVID-19 pandemic, operating results for the periods presented are not necessarily indicative of the operating results to be expected for the full year.

Certain prior year data presented in the financial statements have been reclassified to conform to the current year presentation. These reclassifications had no impact on the overall results of operations, financial position, or cash flows of any Registrant.

Goodwill and Other Intangible Assets

Goodwill at June 30, 2020 and December 31, 2019 was as follows: Goodwill
(in millions)
Southern Company $ 5,280
Southern Company Gas:
Gas distribution operations $ 4,034
Gas marketing services 981
Southern Company Gas total $ 5,015

Goodwill is not amortized but is subject to an annual impairment test in the fourth quarter of the year and on an interim basis as events and changes in circumstances occur, including, but not limited to, a significant change in operating performance, the business climate, legal or regulatory factors, or a planned sale or disposition of a significant portion of the business. The continued COVID-19 pandemic and related responses continue to disrupt supply chains and capital markets, reduce labor availability and productivity, and reduce economic activity. These effects could have a variety of adverse impacts on Southern Company and its subsidiaries, including the $263 million of goodwill recorded at PowerSecure. If the impact of the COVID-19 pandemic becomes significant to the operating results of PowerSecure and its businesses, a portion of the associated goodwill may become impaired. The ultimate outcome of this matter cannot be determined at this time.

Natural Gas for Sale

Southern Company Gas, with the exception of Nicor Gas, carries natural gas inventory on a WACOG basis. For any declines in market prices below the WACOG considered to be other than temporary, an adjustment is recorded to reduce the value of natural gas inventories to market value. Southern Company Gas recorded no material adjustments for the three and six months ended June 30, 2020 and recorded adjustments of $7 million and $10 million for the three and six months ended June 30, 2019, respectively.

Nicor Gas' natural gas inventory is carried at cost on a LIFO basis. Inventory decrements occurring during the year that are restored prior to year end are charged to cost of natural gas at the estimated annual replacement cost. Inventory decrements that are not restored prior to year end are charged to cost of natural gas at the actual LIFO

cost of the inventory layers liquidated. Nicor Gas' inventory decrement at June 30, 2020 is expected to be restored prior to year end.

Asset Retirement Obligations

See Note 6 to the financial statements in Item 8 of the Form 10-K for additional information.

Details of changes in AROs for Southern Company and Alabama Power during the first six months of 2020 are shown in the following table. There were no material changes in AROs for the other Registrants during the first six months of 2020.

Southern Company Alabama Power
(in millions)
Balance at December 31, 2019 $ 9,786 $ 3,540
Liabilities incurred 15
Liabilities settled (193 ) (100 )
Accretion 204 74
Cash flow revisions 462 462
Balance at June 30, 2020 $ 10,274 $ 3,976

In June 2020, Alabama Power recorded an increase of approximately $462 million to its AROs related to the CCR Rule and the related state rule primarily due to management's completion of a feasibility study and the related cost estimates during the second quarter 2020 for one of its ash ponds. Alabama Power's increase also reflects costs associated with the addition of a water treatment system to the design of another ash pond. The additional estimated costs to close these ash ponds under the planned closure-in-place methodology primarily relate to inputs from contractor bids, design revisions, and changes in the expected volume of ash handling.

The traditional electric operating companies expect to continue updating their cost estimates and ARO liabilities periodically as additional information related to ash pond closure methodologies, schedules, and/or costs becomes available. Additionally, the closure designs and plans in the States of Alabama and Georgia are subject to approval by environmental regulatory agencies. Absent continued recovery of ARO costs through regulated rates, results of operations, cash flows, and financial condition for Southern Company and the traditional electric operating companies could be materially impacted. See Note (B) under "Georgia Power – Integrated Resource Plan" for additional information. The ultimate outcome of these matters cannot be determined at this time.

Depreciation and Amortization

See Note 5 to the financial statements under "Depreciation and Amortization – Southern Power" in Item 8 of the Form 10-K for additional information.

Effective January 1, 2020, Southern Power revised the depreciable lives of its natural gas generating facilities from up to 45 years to up to 50 years. This revision resulted in an immaterial decrease in depreciation for the three and six months ended June 30, 2020 and is expected to result in an immaterial decrease in annual depreciation for 2020.

(B) REGULATORY MATTERS

See Note 2 to the financial statements in Item 8 of the Form 10-K for additional information relating to regulatory matters.

Alabama Power

Petition for Certificate of Convenience and Necessity

On June 9, 2020, the Alabama PSC approved in part Alabama Power's petition for a certificate of convenience and necessity (CCN) which authorizes Alabama Power to (i) construct an approximately

720

-MW combined cycle facility at Alabama Power's Plant Barry (Plant Barry Unit 8), which is expected to be placed in service by the end of 2023, (ii) complete the Autauga Combined Cycle Acquisition, which was approved by the FERC on April 22, 2020 and is expected to close by September 1, 2020, (iii) purchase approximately

240

MWs of combined cycle generation under a long-term PPA expected to begin later in 2020 and (iv) pursue up to approximately

200

MWs of certain demand-side management and distributed energy resource programs.

The Alabama PSC authorized the recovery of actual costs for the construction of Plant Barry Unit 8 up to 5% above the estimated in-service cost of $652 million. In so doing, it recognized the potential for developments that could cause the project costs to exceed the capped amount, in which case Alabama Power would provide documentation to the Alabama PSC to explain and justify potential recovery of the additional costs.

The Alabama PSC further directed that the proposed solar generation of approximately

400

MWs, coupled with battery energy storage systems (solar/battery systems), be evaluated under an existing Renewable Generation Certificate issued by the Alabama PSC in September 2015.

Alabama Power expects to recover all approved costs associated with the CCN through existing rate mechanisms as outlined in Note 2 to the financial statements in Item 8 of the Form 10-K. The Alabama PSC's approval in part of

49

(UNAUDITED)

the CCN will be followed by a written order which is subject to any rehearing request or judicial appeal filed within 30 days of the date of such order.

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

Georgia Power

Deferral of Incremental COVID-19 Costs

On April 7, 2020 and June 2, 2020, in response to the COVID-19 pandemic, the Georgia PSC approved orders directing Georgia Power to continue its previous, voluntary suspension of customer disconnections through July 14, 2020 and to defer the resulting incremental bad debt as a regulatory asset. On June 16, 2020 and July 7, 2020, the Georgia PSC approved orders establishing a methodology for identifying incremental bad debt and allowing the deferral of other incremental costs associated with the COVID-19 pandemic. The period over which such costs will be recovered is expected to be determined in Georgia Power's next base rate case. At June 30, 2020, the incremental costs deferred totaled approximately $34 million. The ultimate outcome of this matter cannot be determined at this time.

Integrated Resource Plan

On March 5, 2020, the Sierra Club filed a petition for judicial review in the Superior Court of Fulton County to appeal the Georgia PSC's decision in the 2019 ARP allowing Georgia Power to recover compliance costs for CCR AROs. Georgia Power intervened in the appeal on June 22, 2020. The ultimate outcome of this matter cannot be determined at this time.

Fuel Cost Recovery

On May 28, 2020, the Georgia PSC approved a stipulation agreement among Georgia Power, the staff of the Georgia PSC, and certain intervenors to lower total fuel billings by approximately $740 million over a two-year period effective June 1, 2020. In addition, Georgia Power will further lower fuel billings by approximately $44 million under an interim fuel rider effective June 1, 2020 through September 30, 2020. Georgia Power continues to be allowed to adjust its fuel cost recovery rates under an interim fuel rider prior to its next fuel case if the under or over recovered fuel balance exceeds $200 million. Georgia Power is scheduled to file its next fuel case no later than February 28, 2023.

Nuclear Construction

In 2009, the Georgia PSC certified construction of Plant Vogtle Units 3 and 4, in which Georgia Power holds a

ownership interest. In 2012, the NRC issued the related combined construction and operating licenses, which allowed full construction of the two AP1000 nuclear units (with electric generating capacity of approximately

1,100

MWs each) and related facilities to begin. Until March 2017, construction on Plant Vogtle Units 3 and 4 continued under the Vogtle 3 and 4 Agreement, which was a substantially fixed price agreement. In March 2017, the EPC Contractor filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code.

In connection with the EPC Contractor's bankruptcy filing, Georgia Power, acting for itself and as agent for the other Vogtle Owners, entered into several transitional arrangements to allow construction to continue. In July 2017, Georgia Power, acting for itself and as agent for the other Vogtle Owners, entered into the Vogtle Services Agreement, whereby Westinghouse provides facility design and engineering services, procurement and technical support, and staff augmentation on a time and materials cost basis. The Vogtle Services Agreement provides that it will continue until the start-up and testing of Plant Vogtle Units 3 and 4 are complete and electricity is generated and sold from both units. The Vogtle Services Agreement is terminable by the Vogtle Owners upon 30 days' written notice.

In October 2017, Georgia Power, acting for itself and as agent for the other Vogtle Owners, executed the Bechtel Agreement, a cost reimbursable plus fee arrangement, whereby Bechtel is reimbursed for actual costs plus a base fee and an at-risk fee, which is subject to adjustment based on Bechtel's performance against cost and schedule

targets. Each Vogtle Owner is severally (not jointly) liable for its proportionate share, based on its ownership interest, of all amounts owed to Bechtel under the Bechtel Agreement. The Vogtle Owners may terminate the Bechtel Agreement at any time for their convenience, provided that the Vogtle Owners will be required to pay amounts related to work performed prior to the termination (including the applicable portion of the base fee), certain termination-related costs, and, at certain stages of the work, the applicable portion of the at-risk fee. Bechtel may terminate the Bechtel Agreement under certain circumstances, including certain Vogtle Owner suspensions of work, certain breaches of the Bechtel Agreement by the Vogtle Owners, Vogtle Owner insolvency, and certain other events.

See Note 8 to the financial statements under "Long-term Debt – DOE Loan Guarantee Borrowings" in Item 8 of the Form 10-K for information on the Amended and Restated Loan Guarantee Agreement, including applicable covenants, events of default, mandatory prepayment events, and conditions to borrowing.

Cost and Schedule

Georgia Power's approximate proportionate share of the remaining estimated capital cost to complete Plant Vogtle Units 3 and 4 by the expected in-service dates of November 2021 and November 2022, respectively, is as follows:

(in billions)
Base project capital cost forecast^(a)(b)^ $ 8.4
Construction contingency estimate 0.1
Total project capital cost forecast^(a)(b)^ 8.5
Net investment as of June 30, 2020^(b)^ (6.6 )
Remaining estimate to complete^(a)^ $ 1.9
(a) Excludes financing costs expected to be capitalized through AFUDC of approximately $260 million, of which $52 million had been accrued through June 30, 2020.
--- ---
(b) Net of $1.7 billion received from Toshiba under the Guarantee Settlement Agreement and approximately $188 million in related customer refunds.
--- ---

Georgia Power estimates that its financing costs for construction of Plant Vogtle Units 3 and 4 will total approximately $3.0 billion, of which $2.4 billion had been incurred through June 30, 2020.

As part of its ongoing processes, Southern Nuclear continues to evaluate cost and schedule forecasts on a regular basis to incorporate current information available, particularly in the areas of engineering support, commodity installation, system turnovers, and workforce statistics.

During the second quarter 2020, approximately $194 million of construction contingency was assigned to the base capital cost forecast for cost risks including, among other things, construction productivity, including the April 2020 reduction in workforce designed to mitigate impacts of the COVID-19 pandemic described below, field support, subcontracts, engineering resources, and procurement. The second quarter 2020 assignment of contingency exceeded the remaining balance of the $366 million construction contingency originally established in the second quarter 2018 by approximately $34 million. Through June 30, 2020, assignments of contingency for cost risks also have included, among other factors, construction productivity; craft labor incentives; adding resources for supervision, field support, project management, initial test program, start-up, and operations and engineering support; subcontracts; and procurement. As a result of these factors, Southern Nuclear recommended establishing additional construction contingency, of which Georgia Power's share is approximately $115 million, for further potential risks including, among other factors, construction productivity and expected impacts of the COVID-19 pandemic; adding resources for supervision, field support, project management, initial test program, start-up, and operations and engineering support; subcontracts; and procurement.

After considering the significant level of uncertainty that exists regarding the future recoverability of these costs since the ultimate outcome of these matters is subject to the outcome of future assessments by management, as well as Georgia PSC decisions in future regulatory proceedings, Georgia Power recorded a total pre-tax charge to income

51


Table of Contents                                Index to Financial Statements

NOTES TO THE CONDENSED FINANCIAL STATEMENTS (Continued)

(UNAUDITED)

of $149 million ($111 million after tax) for the increase in the total project capital cost forecast as of June 30, 2020. As and when these amounts are spent, Georgia Power may request the Georgia PSC to evaluate those expenditures for rate recovery.

In April 2019, Southern Nuclear established aggressive target values for monthly construction production and system turnover activities as part of a strategy to maintain and, where possible, build margin to the regulatory-approved in-service dates of November 2021 for Unit 3 and November 2022 for Unit 4. Through early 2020, the project faced challenges with the April 2019 aggressive strategy targets including, but not limited to, electrical and pipefitting labor productivity and work package closure rates, which resulted in a backlog of activities and completion percentages below the April 2019 aggressive strategy targets.

In February 2020, Southern Nuclear updated its cost and schedule forecast, which, at that time, did not change the total project capital cost forecast and confirmed the expected in-service dates of November 2021 for Unit 3 and November 2022 for Unit 4. This update included initiatives to improve productivity while refining and extending system turnover plans and certain near-term milestone dates. Other milestone dates did not change. Achievement of the February 2020 aggressive site work plan relied on meeting increased monthly production and activity target values during 2020.

In mid-March 2020, Southern Nuclear began implementing policies and procedures designed to mitigate the risk of transmission of COVID-19 at the construction site, including worker distancing measures, isolating individuals who have tested positive for COVID-19, are showing symptoms consistent with COVID-19, are being tested for COVID-19, or have been in close contact with such persons, requiring self-quarantine, and adopting additional precautionary measures.

In April 2020, Georgia Power, acting for itself and as agent for the other Vogtle Owners, announced a reduction in workforce at Plant Vogtle Units 3 and 4, which totaled approximately

20%

of the then-existing site workforce. This reduction in workforce was a mitigation action intended to address the impact of the COVID-19 pandemic on the Plant Vogtle Units 3 and 4 workforce and construction site, including challenges with labor productivity that were exacerbated by the impact of the COVID-19 pandemic. The April 2020 workforce reduction was intended to provide operational efficiencies by increasing productivity of the remaining workforce and reducing workforce fatigue and absenteeism. Further, it was also intended to allow for increased social distancing by the workforce and facilitate compliance with the recommendations from the Centers for Disease Control and Prevention. The April 2020 workforce reduction did reduce absenteeism, providing an improvement in operational efficiency and allowing for increased social distancing. From the initial peak in April 2020, the number of active cases at the site declined significantly during May and early June, but began increasing again in mid-June and continues to impact productivity levels and pace of activity completion. As a result of these factors, overall production improvements have not been achieved at the levels anticipated, contributing to the allocation of, and increase in, construction contingency described above. Through mid-July 2020, Unit 3 mechanical, electrical, and subcontract activities continued to build a backlog to Southern Nuclear's February 2020 aggressive site work plan.

To address these issues, in July 2020, Southern Nuclear updated its aggressive site work plan for both Unit 3 and Unit 4. To meet the targets in the July 2020 aggressive site work plan, absenteeism rates must continue to normalize and overall construction productivity and production levels, including subcontractors, must significantly improve and be sustained above pre-pandemic levels. In addition, appropriate levels of craft laborers, particularly electrical and pipefitter craft labor, must be added and maintained. While Southern Nuclear's July 2020 aggressive site work plan extended milestone dates from the February 2020 aggressive site work plan, Georgia Power still expects to achieve the regulatory-approved in-service dates of November 2021 and November 2022 for Plant Vogtle Units 3 and 4, respectively. Southern Nuclear and Georgia Power continue to believe that pursuit of an aggressive site work plan is an appropriate strategy to achieve completion of the units by their regulatory-approved in-service dates.

As construction, including subcontract work, continues and testing and system turnover activities increase, challenges with management of contractors and vendors; subcontractor performance; supervision of craft labor and related productivity, particularly in the installation of electrical, mechanical, and instrumentation and controls commodities, ability to attract and retain craft labor, and/or related cost escalation; procurement, fabrication,

(UNAUDITED)

delivery, assembly, installation, system turnover, and the initial testing and start-up, including any required engineering changes or any remediation related thereto, of plant systems, structures, or components (some of which are based on new technology that only within the last few years began initial operation in the global nuclear industry at this scale), any of which may require additional labor and/or materials; or other issues could arise and change the projected schedule and estimated cost.

In addition, the continuing effects of the COVID-19 pandemic could further disrupt or delay construction, testing, supervisory, and support activities at Plant Vogtle Units 3 and 4. Georgia Power's proportionate share of the estimated incremental cost associated with COVID-19 mitigation actions and impacts on construction productivity is currently estimated to be between $70 million and $115 million, which is included in the total project capital cost forecast and assumes (i) absenteeism rates continue to normalize and (ii) the intended productivity efficiencies and production targets assumed in Southern Nuclear's July 2020 aggressive site work plan are realized in the coming months. However, the ultimate impact of the COVID-19 pandemic on the construction schedule and budget for Plant Vogtle Units 3 and 4 cannot be determined at this time.

There have been technical and procedural challenges to the construction and licensing of Plant Vogtle Units 3 and 4 at the federal and state level and additional challenges may arise. Processes are in place that are designed to assure compliance with the requirements specified in the Westinghouse Design Control Document and the combined construction and operating licenses, including inspections by Southern Nuclear and the NRC that occur throughout construction. As a result of such compliance processes, certain license amendment requests have been filed and approved or are pending before the NRC. Various design and other licensing-based compliance matters, including the timely submittal by Southern Nuclear of the ITAAC documentation for each unit and the related reviews and approvals by the NRC necessary to support NRC authorization to load fuel, may arise, which may result in additional license amendments or require other resolution. As part of the aggressive site work plan, in January 2020, Southern Nuclear notified the NRC of its intent to load fuel in 2020. On May 11, 2020, the Blue Ridge Environmental Defense League filed a petition with the NRC that challenges a license amendment request. On June 15, 2020, the NRC issued an appealable order rejecting Nuclear Watch South's April 20, 2020 petition requesting a hearing and challenging the closure of certain ITAAC. If any license amendment requests or other licensing-based compliance issues are not resolved in a timely manner, there may be delays in the project schedule that could result in increased costs.

The ultimate outcome of these matters cannot be determined at this time. However, any extension of the regulatory-approved project schedule is currently estimated to result in additional base capital costs of approximately $50 million per month, based on Georgia Power's ownership interests, and AFUDC of approximately $10 million per month. While Georgia Power is not precluded from seeking recovery of any future capital cost forecast increase, management will ultimately determine whether or not to seek recovery. Any further changes to the capital cost forecast that are not expected to be recoverable through regulated rates will be required to be charged to income and such charges could be material.

Joint Owner Contracts

In November 2017, the Vogtle Owners entered into an amendment to their joint ownership agreements for Plant Vogtle Units 3 and 4 to provide for, among other conditions, additional Vogtle Owner approval requirements. Effective in August 2018, the Vogtle Owners further amended the joint ownership agreements to clarify and provide procedures for certain provisions of the joint ownership agreements related to adverse events that require the vote of the holders of at least

90%

of the ownership interests in Plant Vogtle Units 3 and 4 to continue construction (as amended, and together with the November 2017 amendment, the Vogtle Joint Ownership Agreements). The Vogtle Joint Ownership Agreements also confirm that the Vogtle Owners' sole recourse against Georgia Power or Southern Nuclear for any action or inaction in connection with their performance as agent for the Vogtle Owners is limited to removal of Georgia Power and/or Southern Nuclear as agent, except in cases of willful misconduct.

As a result of an increase in the total project capital cost forecast and Georgia Power's decision not to seek rate recovery of the increase in the base capital costs in conjunction with the nineteenth VCM report in 2018, the holders of at least

90%

of the ownership interests in Plant Vogtle Units 3 and 4 were required to vote to continue

(UNAUDITED)

construction. In September 2018, the Vogtle Owners unanimously voted to continue construction of Plant Vogtle Units 3 and 4.

Amendments to the Vogtle Joint Ownership Agreements

In connection with the vote to continue construction, Georgia Power entered into (i) a binding term sheet (Vogtle Owner Term Sheet) with the other Vogtle Owners and MEAG Power's wholly-owned subsidiaries MEAG Power SPVJ, LLC (MEAG SPVJ), MEAG Power SPVM, LLC (MEAG SPVM), and MEAG Power SPVP, LLC (MEAG SPVP) to take certain actions which partially mitigate potential financial exposure for the other Vogtle Owners, including additional amendments to the Vogtle Joint Ownership Agreements and the purchase of PTCs from the other Vogtle Owners at pre-established prices, and (ii) a term sheet (MEAG Term Sheet) with MEAG Power and MEAG SPVJ to provide up to $300 million of funding with respect to MEAG SPVJ's ownership interest in Plant Vogtle Units 3 and 4 under certain circumstances. In January 2019, Georgia Power, MEAG Power, and MEAG SPVJ entered into an agreement to implement the provisions of the MEAG Term Sheet. In February 2019, Georgia Power, the other Vogtle Owners, and MEAG Power's wholly-owned subsidiaries MEAG SPVJ, MEAG SPVM, and MEAG SPVP entered into certain amendments to the Vogtle Joint Ownership Agreements to implement the provisions of the Vogtle Owner Term Sheet (Global Amendments).

As previously disclosed, pursuant to the Global Amendments: (i) each Vogtle Owner must pay its proportionate share of qualifying construction costs for Plant Vogtle Units 3 and 4 based on its ownership percentage up to the estimated cost at completion (EAC) for Plant Vogtle Units 3 and 4 which formed the basis of Georgia Power's forecast of $8.4 billion in the nineteenth VCM plus $800 million; (ii) Georgia Power will be responsible for

55.7%

of actual qualifying construction costs between $800 million and $1.6 billion over the EAC in the nineteenth VCM (resulting in $80 million of potential additional costs to Georgia Power), with the remaining Vogtle Owners responsible for

44.3%

of such costs pro rata in accordance with their respective ownership interests; and (iii) Georgia Power will be responsible for

65.7%

of qualifying construction costs between $1.6 billion and $2.1 billion over the EAC in the nineteenth VCM (resulting in a further $100 million of potential additional costs to Georgia Power), with the remaining Vogtle Owners responsible for

34.3%

of such costs pro rata in accordance with their respective ownership interests. If the EAC is revised and exceeds the EAC in the nineteenth VCM by more than $2.1 billion, each of the other Vogtle Owners will have a one-time option at the time the project budget forecast is so revised to tender a portion of its ownership interest to Georgia Power in exchange for Georgia Power's agreement to pay

100%

of such Vogtle Owner's remaining share of total construction costs in excess of the EAC in the nineteenth VCM plus $2.1 billion.

In addition, pursuant to the Global Amendments, the holders of at least

90%

of the ownership interests in Plant Vogtle Units 3 and 4 must vote to continue construction if certain adverse events occur, including, among other events: (i) the bankruptcy of Toshiba; (ii) the termination or rejection in bankruptcy of certain agreements, including the Vogtle Services Agreement, the Bechtel Agreement, or the agency agreement with Southern Nuclear; (iii) Georgia Power's public announcement of its intention not to submit for rate recovery any portion of its investment in Plant Vogtle Units 3 and 4 or the Georgia PSC determines that any of Georgia Power's costs relating to the construction of Plant Vogtle Units 3 and 4 will not be recovered in retail rates, excluding any additional amounts paid by Georgia Power on behalf of the other Vogtle Owners pursuant to the Global Amendments described above and the first 6% of costs during any six-month VCM reporting period that are disallowed by the Georgia PSC for recovery, or for which Georgia Power elects not to seek cost recovery, through retail rates; and (iv) an incremental extension of one year or more over the most recently approved schedule.

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

Regulatory Matters

In 2009, the Georgia PSC voted to certify construction of Plant Vogtle Units 3 and 4 with a certified capital cost of $4.418 billion. In addition, in 2009 the Georgia PSC approved inclusion of the Plant Vogtle Units 3 and 4 related CWIP accounts in rate base, and the State of Georgia enacted the Georgia Nuclear Energy Financing Act, which allows Georgia Power to recover financing costs for Plant Vogtle Units 3 and 4. Financing costs are recovered on all

54


Table of Contents                                Index to Financial Statements

NOTES TO THE CONDENSED FINANCIAL STATEMENTS (Continued)

(UNAUDITED)

applicable certified costs through annual adjustments to the NCCR tariff up to the certified capital cost of $4.418 billion. At June 30, 2020, Georgia Power had recovered approximately $2.4 billion of financing costs. Financing costs related to capital costs above $4.418 billion are being recognized through AFUDC and are expected to be recovered through retail rates over the life of Plant Vogtle Units 3 and 4; however, Georgia Power will not record AFUDC related to any capital costs in excess of the total deemed reasonable by the Georgia PSC (currently $7.3 billion) and not requested for rate recovery. In December 2019, the Georgia PSC approved Georgia Power's request to decrease the NCCR tariff by $62 million annually, effective January 1, 2020.

Georgia Power is required to file semi-annual VCM reports with the Georgia PSC by February 28 and August 31 of each year. In 2013, in connection with the eighth VCM report, the Georgia PSC approved a stipulation between Georgia Power and the staff of the Georgia PSC to waive the requirement to amend the Plant Vogtle Units 3 and 4 certificate in accordance with the 2009 certification order until the completion of Plant Vogtle Unit 3, or earlier if deemed appropriate by the Georgia PSC and Georgia Power.

In 2016, the Georgia PSC voted to approve a settlement agreement (Vogtle Cost Settlement Agreement) resolving certain prudency matters in connection with the fifteenth VCM report. In December 2017, the Georgia PSC voted to approve (and issued its related order on January 11, 2018) Georgia Power's seventeenth VCM report and modified the Vogtle Cost Settlement Agreement. The Vogtle Cost Settlement Agreement, as modified by the January 11, 2018 order, resolved the following regulatory matters related to Plant Vogtle Units 3 and 4: (i) none of the $3.3 billion of costs incurred through December 31, 2015 and reflected in the fourteenth VCM report should be disallowed from rate base on the basis of imprudence; (ii) the Contractor Settlement Agreement was reasonable and prudent and none of the amounts paid pursuant to the Contractor Settlement Agreement should be disallowed from rate base on the basis of imprudence; (iii) (a) capital costs incurred up to $5.68 billion would be presumed to be reasonable and prudent with the burden of proof on any party challenging such costs, (b) Georgia Power would have the burden to show that any capital costs above $5.68 billion were prudent, and (c) a revised capital cost forecast of $7.3 billion (after reflecting the impact of payments received under the Guarantee Settlement Agreement and related customer refunds) was found reasonable; (iv) construction of Plant Vogtle Units 3 and 4 should be completed, with Southern Nuclear serving as project manager and Bechtel as primary contractor; (v) approved and deemed reasonable Georgia Power's revised schedule placing Plant Vogtle Units 3 and 4 in service in November 2021 and November 2022, respectively; (vi) confirmed that the revised cost forecast does not represent a cost cap and that prudence decisions on cost recovery will be made at a later date, consistent with applicable Georgia law; (vii) reduced the ROE used to calculate the NCCR tariff (a) from

10.95%

(the ROE rate setting point authorized by the Georgia PSC in the 2013 ARP) to

10.00%

effective January 1, 2016, (b) from

10.00%

to

8.30%

, effective January 1, 2020, and (c) from

8.30%

to

5.30%

, effective January 1, 2021 (provided that the ROE in no case will be less than Georgia Power's average cost of long-term debt); (viii) reduced the ROE used for AFUDC equity for Plant Vogtle Units 3 and 4 from

10.00%

to Georgia Power's average cost of long-term debt, effective January 1, 2018; and (ix) agreed that upon Unit 3 reaching commercial operation, retail base rates would be adjusted to include carrying costs on those capital costs deemed prudent in the Vogtle Cost Settlement Agreement. The January 11, 2018 order also stated that if Plant Vogtle Units 3 and 4 are not commercially operational by June 1, 2021 and June 1, 2022, respectively, the ROE used to calculate the NCCR tariff will be further reduced by 10 basis points each month (but not lower than Georgia Power's average cost of long-term debt) until the respective Unit is commercially operational. The ROE reductions negatively impacted earnings by approximately $75 million in 2019 and are estimated to have negative earnings impacts of approximately $145 million, $255 million, and $200 million in 2020, 2021, and 2022, respectively. In its January 11, 2018 order, the Georgia PSC also stated if other conditions change and assumptions upon which Georgia Power's seventeenth VCM report are based do not materialize, the Georgia PSC reserved the right to reconsider the decision to continue construction.

In February 2018, Georgia Interfaith Power & Light, Inc. (GIPL) and Partnership for Southern Equity, Inc. (PSE) filed a petition appealing the Georgia PSC's January 11, 2018 order with the Fulton County Superior Court. In March 2018, Georgia Watch filed a similar appeal to the Fulton County Superior Court for judicial review of the Georgia PSC's decision and denial of Georgia Watch's motion for reconsideration. In December 2018, the Fulton County Superior Court granted Georgia Power's motion to dismiss the two appeals. In January 2019, GIPL, PSE,

55


Table of Contents                                Index to Financial Statements

NOTES TO THE CONDENSED FINANCIAL STATEMENTS (Continued)

(UNAUDITED)

and Georgia Watch filed an appeal of this decision with the Georgia Court of Appeals. In October 2019, the Georgia Court of Appeals issued an opinion affirming the Fulton County Superior Court's ruling that the Georgia PSC's January 11, 2018 order was not a final, appealable decision. In addition, the Georgia Court of Appeals remanded the case to the Fulton County Superior Court to clarify its ruling as to whether the petitioners showed that review of the Georgia PSC's final order would not provide them an adequate remedy. On April 21, 2020, the Fulton County Superior Court granted Georgia Power's motion to dismiss the two appeals. The petitioners filed a notice of appeal of the dismissal on May 20, 2020. Georgia Power believes the petitions have no merit; however, an adverse outcome in the litigation combined with subsequent adverse action by the Georgia PSC could have a material impact on Southern Company's and Georgia Power's results of operations, financial condition, and liquidity.

The Georgia PSC has approved 21 VCM reports covering the periods through June 30, 2019, including total construction capital costs incurred through that date of $6.7 billion (before $1.7 billion of payments received under the Guarantee Settlement Agreement and approximately $188 million in related customer refunds). On August 18, 2020, the Georgia PSC is scheduled to vote on Georgia Power's twenty-second VCM report, which requested approval of $674 million of construction capital costs incurred from July 1, 2019 through December 31, 2019.

Georgia Power expects to file its twenty-third VCM report with the Georgia PSC by August 31, 2020, which will reflect the revised capital cost forecast discussed above and request approval of $701 million of construction capital costs incurred from January 1, 2020 through June 30, 2020.

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

Mississippi Power

2019 Base Rate Case

On March 17, 2020, the Mississippi PSC approved a settlement agreement between Mississippi Power and the Mississippi Public Utilities Staff related to Mississippi Power's base rate case filed in November 2019 (Mississippi Power Rate Case Settlement Agreement).

Under the terms of the Mississippi Power Rate Case Settlement Agreement, annual retail rates decreased approximately $16.7 million, or

1.85%

, effective for the first billing cycle of April 2020, 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.

Additionally, the approved Mississippi Power Rate Case Settlement Agreement: (i) established common amortization periods of four years for regulatory assets and three years for regulatory liabilities included in the approved revenue requirement, including those related to unprotected deferred income taxes; (ii) established new depreciation rates reflecting an annual increase in depreciation of approximately $10 million; and (iii) excluded certain compensation costs totaling approximately $3.9 million. It also eliminated separate rates for costs associated with Plant Ratcliffe and energy efficiency initiatives and includes such costs in the PEP, ECO Plan, and ad valorem tax adjustment factor, as applicable. In accordance with the previous order of the Mississippi PSC suspending the operation of PEP and the ECO Plan for 2018 through 2020, Mississippi Power plans to resume PEP proceedings and ECO Plan filings for 2021.

Performance Evaluation Plan

On July 24, 2020, the Mississippi PSC approved Mississippi Power's July 14, 2020 filing of its PEP compliance rate clause reflecting revisions agreed to in the Mississippi Power Rate Case Settlement Agreement. These revisions include, among other things, changing the filing date for the annual PEP rate filing from November of the immediately preceding year to March of the current 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.

Deferral of Incremental COVID-19 Costs

On April 14, 2020 and May 12, 2020, in order to mitigate the economic impact of the COVID-19 pandemic on customers, the Mississippi PSC approved orders directing Mississippi Power to continue its previous, voluntary suspension of customer disconnections through May 25, 2020 and to defer as a regulatory asset all necessary and reasonable incremental costs or expenses to plan, prepare, stage, or react to protect and keep safe its employees and customers, and to reliably operate its utility system during the COVID-19 pandemic. The period over which such costs will be recovered is expected to be determined in a future PEP filing. At June 30, 2020, the incremental costs deferred totaled approximately $2 million. The ultimate outcome of this matter cannot be determined at this time.

Municipal and Rural Associations Tariff

On June 25, 2020, the FERC accepted Mississippi Power's April 27, 2020 request for an increase in wholesale base revenues under the MRA tariff as agreed upon in a settlement agreement reached with its wholesale customers. The MRA settlement agreement resulted in a $2 million annual increase in base rates effective June 1, 2020.

Southern Company Gas

Rate Proceedings

On June 1, 2020, Virginia Natural Gas filed a general rate case with the Virginia Commission seeking an increase in rates of $49.6 million primarily to recover investments and increased costs associated with infrastructure, technology, and workforce development. The requested increase is based on a projected 12-month test year beginning November 1, 2020, a ROE of

10.35%

, and an equity ratio of

54%

. Rate adjustments are expected to be effective November 1, 2020, subject to refund. The Virginia Commission is expected to rule on the requested increase in the second quarter 2021.

On July 1, 2020, Atlanta Gas Light filed its 2020 GRAM filing with the Georgia PSC. The filing requests an annual base rate increase of $37.6 million based on the projected 12-month period beginning January 1, 2021, which does not exceed the 5% limitation established by the Georgia PSC in its December 2019 approval of Atlanta Gas Light's general base rate case. Resolution of the 2020 GRAM filing is expected by December 31, 2020, with rates effective January 1, 2021.

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

Deferral of Incremental COVID-19 Costs

Atlanta Gas Light

On April 30, 2020, in response to the COVID-19 pandemic, the Georgia PSC approved orders directing Atlanta Gas Light to continue its previous, voluntary suspension of customer disconnections. On June 22, 2020, the Georgia PSC ordered Atlanta Gas Light to resume customer disconnections beginning July 1, 2020, with exceptions for customers still covered by a shelter-in-place order. The orders provide the Marketers, including SouthStar, with a mechanism to receive credits from Atlanta Gas Light for the base rates it charged to the Marketers of non-paying customers during the suspension. Atlanta Gas Light expects to recover these credits through the annual revenue true-up process within its 2021 GRAM filing, which would impact rates effective January 1, 2022. The ultimate outcome of this matter cannot be determined at this time.

Nicor Gas

On March 18, 2020, the Illinois Commission issued an order directing utilities to cease disconnections for non-payment and to suspend the imposition of late payment fees or penalties until the Governor of Illinois announces the end of the COVID-19 state of emergency. In response to this order, on March 27, 2020, Nicor Gas and other utilities in Illinois filed their plans seeking cost recovery and more flexible credit and collection plans.

On June 18, 2020, the Illinois Commission approved a stipulation pursuant to which the utilities will provide more flexible credit and collection procedures to assist customers with financial hardship and which authorizes a special

purpose rider for recovery of the following COVID-19 pandemic-related impacts: incremental costs directly associated with the COVID-19 pandemic, net of the offset for COVID-19 pandemic-related credits received, foregone late fees, foregone reconnection charges, and the costs associated with a bill payment assistance program. The special purpose rider is proposed to be effective on October 1, 2020 and continue over a 24-month period. At June 30, 2020, Nicor Gas' related regulatory asset was $12 million. The ultimate outcome of this matter cannot be determined at this time.

Virginia Natural Gas

In response to the COVID-19 pandemic, the Virginia Commission issued orders requiring Virginia Natural Gas to suspend disconnections beginning on March 16, 2020 and also to suspend late payment and reconnection fees beginning on April 9, 2020, both of which continue in effect through August 31, 2020. On April 29, 2020, the Virginia Commission authorized Virginia Natural Gas to defer the following COVID-19 pandemic-related costs as a regulatory asset: incremental uncollectible expense incurred, suspended late fees, suspended reconnection charges, carrying costs, and other incremental prudently incurred costs associated with the COVID-19 pandemic. Specific recovery of the amounts deferred in a regulatory asset will be addressed in a future rate proceeding. At June 30, 2020, Virginia Natural Gas' related regulatory asset was $1 million. The ultimate outcome of this matter cannot be determined at this time.

Infrastructure Replacement Programs and Capital Projects

In December 2019, Virginia Natural Gas filed an application with the Virginia Commission for a 24.1-mile header improvement project to improve resiliency and increase the supply of natural gas delivered to energy suppliers, including Virginia Natural Gas. On June 26, 2020, the Virginia Commission issued an order requiring Virginia Natural Gas to submit additional information by December 31, 2020 related to the financing plans of the project's primary customer before ruling on the December 2019 application. The ultimate outcome of this matter cannot be determined at this time.

General Litigation Matters

The Registrants are involved in various other matters being litigated and regulatory matters. The ultimate outcome of such pending or potential litigation or regulatory matters against each Registrant and any subsidiaries cannot be determined at this time; however, for current proceedings not specifically reported herein, management does not anticipate that the ultimate liabilities, if any, arising from such current proceedings would have a material effect on such Registrant's financial statements.

The Registrants believe the pending legal challenges discussed below have no merit; however, the ultimate outcome of these matters cannot be determined at this time.

Southern Company

In January 2017, a securities class action complaint was filed in the U.S. District Court for the Northern District of Georgia by Monroe County Employees' Retirement System on behalf of all persons who purchased shares of Southern Company's common stock between April 25, 2012 and October 29, 2013. The complaint names as defendants Southern Company, certain of its current and former officers, and certain former Mississippi Power officers and alleges that the defendants made materially false and misleading statements regarding the Kemper County energy facility in violation of certain provisions under the Securities Exchange Act of 1934, as amended. The complaint seeks, among other things, compensatory damages and litigation costs and attorneys' fees. In 2017, the plaintiffs filed an amended complaint that provided additional detail about their claims, increased the purported class period by one day, and added certain other former Mississippi Power officers as defendants. Also in 2017, the defendants filed a motion to dismiss the plaintiffs' amended complaint with prejudice, to which the plaintiffs filed an

opposition. In 2018, the court issued an order dismissing certain claims against certain officers of Southern Company and Mississippi Power and dismissing the allegations related to a number of the statements that plaintiffs challenged as being false or misleading. In 2018, the court denied the defendants' motion for reconsideration and also denied a motion to certify the issue for interlocutory appeal. In the third quarter 2019, the court certified the plaintiffs' proposed class and the defendants filed a petition for interlocutory appeal of the class certification order with the U.S. Court of Appeals for the Eleventh Circuit. In December 2019, the U.S. District Court for the Northern District of Georgia entered an order staying all deadlines in the case pending mediation. The stay automatically expired on March 31, 2020; however, in light of the COVID-19 pandemic, the U.S. District Court for the Northern District of Georgia vacated all existing discovery deadlines until June 15, 2020. On June 30, 2020, the court entered a revised scheduling order, which resumed discovery and set out remaining case deadlines.

In February 2017, Jean Vineyard and Judy Mesirov each filed a shareholder derivative lawsuit in the U.S. District Court for the Northern District of Georgia. Each of these lawsuits names as defendants Southern Company, certain of its directors, certain of its current and former officers, and certain former Mississippi Power officers. In 2017, these two shareholder derivative lawsuits were consolidated in the U.S. District Court for the Northern District of Georgia. The complaints allege that the defendants caused Southern Company to make false or misleading statements regarding the Kemper County energy facility cost and schedule. Further, the complaints allege that the defendants were unjustly enriched and caused the waste of corporate assets and also allege that the individual defendants violated their fiduciary duties. Each plaintiff seeks to recover, on behalf of Southern Company, unspecified actual damages and, on each plaintiff's own behalf, attorneys' fees and costs in bringing the lawsuit. Each plaintiff also seeks certain changes to Southern Company's corporate governance and internal processes. In 2018, the court entered an order staying this lawsuit until 30 days after the resolution of any dispositive motions or any settlement, whichever is earlier, in the securities class action.

In May 2017, Helen E. Piper Survivor's Trust filed a shareholder derivative lawsuit in the Superior Court of Gwinnett County, Georgia that names as defendants Southern Company, certain of its directors, certain of its current and former officers, and certain former Mississippi Power officers. The complaint alleges that the individual defendants, among other things, breached their fiduciary duties in connection with schedule delays and cost overruns associated with the construction of the Kemper County energy facility. The complaint further alleges that the individual defendants authorized or failed to correct false and misleading statements regarding the Kemper County energy facility schedule and cost and failed to implement necessary internal controls to prevent harm to Southern Company. The plaintiff seeks to recover, on behalf of Southern Company, unspecified actual damages and disgorgement of profits and, on its behalf, attorneys' fees and costs in bringing the lawsuit. The plaintiff also seeks certain unspecified changes to Southern Company's corporate governance and internal processes. In 2018, the court entered an order staying this lawsuit until 30 days after the resolution of any dispositive motions or any settlement, whichever is earlier, in the securities class action. In August 2019, the court granted a motion filed by the plaintiff in July 2019 to substitute a new named plaintiff, Martin J. Kobuck, in place of Helen E. Piper Survivor's Trust.

Georgia Power

In 2011, plaintiffs filed a putative class action against Georgia Power in the Superior Court of Fulton County, Georgia alleging that Georgia Power's collection in rates of amounts for municipal franchise fees (which fees are paid to municipalities) exceeded the amounts allowed in orders of the Georgia PSC and alleging certain state law claims. This case has been ruled upon and appealed numerous times over the last several years. In one recent appeal, the Georgia Supreme Court remanded the case and noted that the trial court could refer the matter to the Georgia PSC to interpret its tariffs. Following a motion by Georgia Power, in February 2019, the Superior Court of Fulton County ordered the parties to submit petitions to the Georgia PSC for a declaratory ruling and also conditionally certified the proposed class. In March 2019, Georgia Power and the plaintiffs filed petitions with the Georgia PSC seeking confirmation of the proper application of the municipal franchise fee schedule pursuant to the Georgia PSC's orders. Also in March 2019, Georgia Power appealed the class certification decision to the Georgia Court of Appeals. In October 2019, the Georgia PSC issued an order that found Georgia Power has appropriately implemented the municipal franchise fee schedule. On March 11, 2020, the Georgia Court of Appeals vacated the Superior Court of Fulton County's February 2019 order granting conditional class certification. The Court of

(UNAUDITED)

Appeals remanded the case to the Superior Court of Fulton County for further proceedings. The amount of any possible losses cannot be calculated at this time because, among other factors, it is unknown whether a class will be certified, the ultimate composition of any class, and whether any losses would be subject to recovery from any municipalities.

On July 29, 2020, a group of individual plaintiffs filed a complaint in the Superior Court of Fulton County, Georgia against Georgia Power alleging that releases from Plant Scherer have impacted groundwater, surface water, and air, resulting in alleged personal injuries and property damage. The plaintiffs seek an unspecified amount of monetary damages including punitive damages, a medical monitoring fund, and injunctive relief.

Mississippi Power

In May 2018, Southern Company and Mississippi Power received a notice of dispute and arbitration demand filed by Martin Product Sales, LLC (Martin) based on two agreements, both related to Kemper IGCC byproducts for which Mississippi Power provided termination notices in 2017. Martin alleges breach of contract, breach of good faith and fair dealing, fraud and misrepresentation, and civil conspiracy and makes a claim for damages in the amount of approximately $143 million, as well as additional unspecified damages, attorney's fees, costs, and interest. A portion of the claim for damages was on behalf of Martin Transport, Inc. (Martin Transport), an affiliate of Martin. In May 2019, the arbitration panel denied Mississippi Power's and Southern Company's motions to dismiss. In September 2019, Martin Transport filed a separate complaint against Mississippi Power in the Circuit Court of Kemper County, Mississippi alleging claims of fraud, negligent misrepresentation, promissory estoppel, and equitable estoppel, each arising out of the same alleged facts and circumstances that underlie Martin's arbitration demand. Martin Transport seeks compensatory damages of $5 million and punitive damages of $50 million. In November 2019, Martin Transport's claim was combined with the Martin arbitration case and the separate court case was dismissed. In December 2019, Southern Company and Mississippi Power each filed motions for summary judgment on all claims. On February 17, 2020, the arbitration panel granted Southern Company's motion and dismissed Southern Company from the arbitration. On March 12, 2020, the arbitration panel denied Mississippi Power's motions for summary judgment. An adverse outcome in this proceeding could have a material impact on Southern Company's and Mississippi Power's financial statements.

In November 2018, Ray C. Turnage and 10 other individual plaintiffs filed a putative class action complaint against Mississippi Power and the three then-serving members of the Mississippi PSC in the U.S. District Court for the Southern District of Mississippi. Mississippi Power received Mississippi PSC approval in 2013 to charge a mirror CWIP rate premised upon including in its rate base pre-construction and construction costs for the Kemper IGCC prior to placing the Kemper IGCC into service. The Mississippi Supreme Court reversed that approval and ordered Mississippi Power to refund the amounts paid by customers under the previously-approved mirror CWIP rate. The plaintiffs allege that the initial approval process, and the amount approved, were improper. They also allege that Mississippi Power underpaid customers by up to $23.5 million in the refund process by applying an incorrect interest rate. The plaintiffs seek to recover, on behalf of themselves and their putative class, actual damages, punitive damages, pre-judgment interest, post-judgment interest, attorney's fees, and costs. In response to Mississippi Power and the Mississippi PSC each filing a motion to dismiss, the plaintiffs filed an amended complaint in March 2019. The amended complaint included four additional plaintiffs and additional claims for gross negligence, reckless conduct, and intentional wrongdoing. Mississippi Power and the Mississippi PSC have each filed a motion to dismiss the amended complaint. On March 27, 2020, the Mississippi PSC's motion to dismiss was granted. Also on March 27, 2020, the plaintiffs filed a motion seeking to name the new members of the Mississippi PSC, the Mississippi Development Authority, and Southern Company as additional defendants and add a cause of action against all defendants based on a dormant commerce clause theory under the U.S. Constitution. On April 9, 2020 and April 10, 2020, Mississippi Power and the Mississippi PSC, respectively, filed responses opposing the motion for leave to file a second amended complaint. On May 26, 2020, Mississippi Power's motion to dismiss the first amended complaint filed in 2019 was granted. On July 6, 2020, the plaintiffs filed a motion for revision of the court's decision. The plaintiffs' motion for leave to file a second amended complaint also remains pending before the court. An adverse outcome in this proceeding could have a material impact on Mississippi Power's financial statements.

Environmental Remediation

The Southern Company system must comply with environmental laws and regulations governing the handling and disposal of waste and releases of hazardous substances. Under these various laws and regulations, the Southern Company system could incur substantial costs to clean up affected sites. The traditional electric operating companies and the natural gas distribution utilities in Illinois and Georgia have each received authority from their respective state PSCs or other applicable state regulatory agencies to recover approved environmental compliance costs through regulatory mechanisms. These regulatory mechanisms are adjusted annually or as necessary within limits approved by the state PSCs or other applicable state regulatory agencies.

Georgia Power's environmental remediation liability was $14 million and $15 million as of June 30, 2020 and December 31, 2019, respectively. Georgia Power has been designated or identified as a potentially responsible party at sites governed by the Georgia Hazardous Site Response Act and/or by the federal Comprehensive Environmental Response, Compensation, and Liability Act, and assessment and potential cleanup of such sites is expected.

In December 2019, Mississippi Power entered into an agreement with the Mississippi Commission on Environmental Quality related to groundwater conditions arising from the closed ash pond at Plant Watson. Mississippi Power will complete an assessment and remediation consistent with the requirements of the agreement and the CCR Rule. Potential remediation activities and related cost estimates are pending the result of further site assessment and cannot be determined at this time. Mississippi Power expects to recover the retail portion of remedial costs through the ECO Plan and the wholesale portion through MRA rates.

Southern Company Gas' environmental remediation liability was $253 million and $269 million as of June 30, 2020 and December 31, 2019, respectively, based on the estimated cost of environmental investigation and remediation associated with known current and former manufactured gas plant operating sites. These environmental remediation expenditures are generally recoverable from customers through rate mechanisms approved by the applicable state regulatory agencies of the natural gas distribution utilities.

The ultimate outcome of these matters cannot be determined at this time; however, as a result of the regulatory treatment for environmental remediation expenses described above, the final disposition of these matters is not expected to have a material impact on the financial statements of the applicable Registrants.

Other Matters

Southern Company

See Notes 1 and 3 under "Leveraged Leases" and "Other Matters – Southern Company," respectively, in Item 8 of the Form 10-K for discussion of challenges associated with a leveraged lease agreement with a subsidiary of Southern Holdings. While all required lease payments through June 30, 2020 have been paid in full, the operational and remarketing risks and the resulting cash liquidity challenges persist and significant concerns continue regarding the lessee's ability to make the remaining required semi-annual lease payments to the Southern Holdings subsidiary through the term of the lease.

In its annual impairment analysis of the expected residual value of the generation assets and the overall collectability of the related lease receivable, Southern Company uses multiple scenarios of long-term market energy prices to estimate the cash flows expected to be received from remarketing the generation assets following the expiration of the existing PPA in 2032 and the residual value of the generation assets at the end of the lease in 2047. Southern Company received the latest annual forecasts of natural gas prices during the second quarter 2020 and considered the significant decline in forecasted prices to be an indicator of potential impairment that required an interim impairment assessment. Accordingly, consistent with prior years, Southern Company evaluated the recoverability of the lease receivable and the expected residual value of the generation assets under various natural gas price scenarios. Based on the current forecasts of energy prices in the years following the expiration of the

61


Table of Contents                                Index to Financial Statements

NOTES TO THE CONDENSED FINANCIAL STATEMENTS (Continued)

(UNAUDITED)

existing PPA, Southern Company concluded that it is no longer probable that any of the associated rental payments will be received, because it is no longer probable the generation assets will be successfully remarketed and continue to operate after that date. During the second quarter 2020, Southern Company revised the estimated cash flows to be received under the leveraged lease to reflect this conclusion, which resulted in a full impairment of the lease investment and a pre-tax charge to earnings of $154 million ($74 million after tax).

If any future lease payment due prior to the expiration of the associated PPA is not paid in full, the Southern Holdings subsidiary may be unable to make its corresponding payment to the holders of the underlying non-recourse debt related to the generation assets. Failure to make the required payment to the debtholders could represent an event of default that would give the debtholders the right to foreclose on, and take ownership of, the generation assets, in effect terminating the lease. As the full amount of the lease investment has been charged against earnings as of June 30, 2020, termination would not be expected to result in additional charges. Southern Company will continue to monitor the operational performance of the underlying assets and evaluate the ability of the lessee to continue to make the required lease payments and meet its obligations associated with a future closure or retirement of the generation assets and associated properties, including the dry ash landfill.

Mississippi Power

Kemper County Energy Facility

See Note 2 to the financial statements under "Mississippi Power – Kemper County Energy Facility" in Item 8 of the Form 10-K for additional information.

As the mining permit holder, Liberty Fuels Company, LLC has a legal obligation to perform mine reclamation and Mississippi Power has a contractual obligation to fund all reclamation activities related to the lignite mine and equipment and mineral reserves located around the Kemper County energy facility site. As a result of the abandonment of the Kemper IGCC, final mine reclamation began in 2018 and is expected to be substantially completed in 2020, with monitoring expected to continue through 2027. See Note 6 to the financial statements in Item 8 of the Form 10-K for additional information.

Dismantlement of the abandoned gasifier-related assets and site restoration activities are expected to be completed in 2025. The additional pre-tax period costs associated with dismantlement and site restoration activities, including related costs for compliance and safety, ARO accretion, and property taxes, are estimated to total $5 million for the remainder of 2020, $16 million in 2021, and $11 million to $13 million annually in 2022 through 2025. In addition, closure costs for the mine and gasifier-related assets, currently estimated at up to $6 million pre-tax (excluding dismantlement costs, net of salvage), may be incurred during the remainder of 2020.

In December 2019, Mississippi Power transferred ownership of the CO2 pipeline to an unrelated gas pipeline company, with no resulting impact on income. In conjunction with the transfer of the CO2 pipeline, the parties agreed to enter into a 15-year firm transportation agreement, which is expected to be signed by the end of 2020, providing for the conversion by the pipeline company of the CO2 pipeline to a natural gas pipeline to be used for the delivery of natural gas to Plant Ratcliffe. The agreement will be treated as a finance lease for accounting purposes upon commencement.

In 2018, Mississippi Power filed with the DOE its request for property closeout certification under the contract related to the $387 million of grants received for the Kemper County energy facility. Mississippi Power expects to close out the DOE contract in 2020. In connection with the DOE closeout discussions, in April 2019, the Civil Division of the Department of Justice informed Southern Company and Mississippi Power of an investigation related to the Kemper County energy facility. The ultimate outcome of this matter cannot be determined at this time; however, it could have a material impact on Southern Company's and Mississippi Power's financial statements.

Plant Daniel

In conjunction with Southern Company's sale of Gulf Power, Mississippi Power and Gulf Power agreed to seek a restructuring of their

50%

undivided ownership interests in Plant Daniel such that each of them would, after the restructuring, own

100%

of a generating unit. On April 24, 2020, Mississippi Power and Gulf Power amended the

62


Table of Contents                                Index to Financial Statements

NOTES TO THE CONDENSED FINANCIAL STATEMENTS (Continued)

(UNAUDITED)

terms of the agreement to extend the deadline from May 1, 2020 to August 1, 2020 for Mississippi Power to notify Gulf Power of which generating unit it has selected for

100%

ownership. Mississippi Power and Gulf Power are continuing negotiations on a mutually acceptable revised operating agreement for Plant Daniel and, as a result, the parties have agreed not to select a specific unit on August 1, 2020. The impacts of operating the units on an individual basis continue to be evaluated by Mississippi Power and any transfer of ownership would be subject to approval by the FERC and the Mississippi PSC. The ultimate outcome of this matter cannot be determined at this time.

Southern Company Gas

See Notes 3 and 7 to the financial statements in Item 8 of the Form 10-K under "Other Matters – Southern Company Gas" and "Southern Company Gas," respectively, and Note (E) under "Southern Company Gas" for additional information.

On March 24, 2020, Southern Company Gas completed the sale of its interest in Atlantic Coast Pipeline. See Note (K) under "Southern Company Gas" for additional information.

On February 20, 2020, the FERC approved a two-year extension for PennEast Pipeline to complete the project by January 19, 2022.

In September 2019, an appellate court ruled that the PennEast Pipeline does not have federal eminent domain authority over lands in which a state has property rights interests. On June 29, 2020, the U.S. Supreme Court requested the U.S. Solicitor General to provide an opinion on PennEast Pipeline's petition for a writ of certiorari seeking its review of the appellate court's decision.

Expected project costs related to the PennEast Pipeline for Southern Company Gas total approximately $300 million, excluding financing costs. The ultimate outcome of the PennEast Pipeline construction project cannot be determined at this time; however, any work delays, whether caused by judicial or regulatory action, abnormal weather, or other conditions, may result in additional cost or schedule modifications or, ultimately, in project cancellation, any of which could result in impairment of Southern Company Gas' investment and could have a significant impact on Southern Company's financial statements and a material impact on Southern Company Gas' financial statements.

(D) REVENUE FROM CONTRACTS WITH CUSTOMERS AND LEASE INCOME

Contract Balances

The following table reflects the closing balances of receivables, contract assets, and contract liabilities related to revenues from contracts with customers at June 30, 2020 and December 31, 2019:

Southern Company Alabama Power Georgia Power Mississippi Power Southern Power Southern Company Gas

As of December 31, 2019 52 10 13 1 1

As of June 30, 2020 and December 31, 2019, Georgia Power had contract assets primarily related to unregulated service agreements, where payment is contingent on project completion, and fixed retail customer bill programs, where the payment is contingent upon Georgia Power's continued performance and the customer's continued participation in the program over a one-year contract term. Contract liabilities for Georgia Power relate to cash collections recognized in advance of revenue for certain unregulated service agreements. Alabama Power had contract liabilities for outstanding performance obligations primarily related to extended service agreements. Southern Company's unregulated distributed generation business had $41 million and $40 million of contract assets and $26 million and $28 million of contract liabilities at June 30, 2020 and December 31, 2019, respectively, for outstanding performance obligations.

Revenues recognized by Southern Company in the three and six months ended June 30, 2020, which were included in contract liabilities at December 31, 2019, were $11 million and $21 million, respectively, and immaterial for all other applicable Registrants.

Remaining Performance Obligations

The traditional electric operating companies and Southern Power have long-term contracts with customers in which revenues are recognized as performance obligations are satisfied over the contract term. These contracts primarily relate to PPAs whereby the traditional electric operating companies and Southern Power provide electricity and generation capacity to a customer. The revenue recognized for the delivery of electricity is variable; however, certain PPAs include a fixed payment for fixed generation capacity over the term of the contract. Southern Company's unregulated distributed generation business also has partially satisfied performance obligations related to certain fixed price contracts. Revenue from contracts with customers related to these performance obligations remaining at June 30, 2020 are expected to be recognized as follows:

(E) CONSOLIDATED ENTITIES AND EQUITY METHOD INVESTMENTS

See Note 7 to the financial statements in Item 8 of the Form 10-K for additional information.

Southern Power

Variable Interest Entities

Southern Power has certain subsidiaries that are determined to be VIEs. Southern Power is considered the primary beneficiary of these VIEs because it controls the most significant activities of the VIEs, including operating and maintaining the respective assets, and has the obligation to absorb expected losses of these VIEs to the extent of its equity interests.

SP Solar and SP Wind

At June 30, 2020 and December 31, 2019, SP Solar had total assets of $6.2 billion and $6.4 billion, respectively, and total liabilities of $381 million. Noncontrolling interests totaled $1.1 billion at both June 30, 2020 and December 31, 2019. Cash distributions from SP Solar are allocated

67%

to Southern Power and

33%

to Global Atlantic in accordance with their partnership interest percentage. Under the terms of the limited partnership agreement, distributions without limited partner consent are limited to available cash and SP Solar is obligated to distribute all such available cash to its partners each quarter. Available cash includes all cash generated in the quarter subject to the maintenance of appropriate operating reserves.

At June 30, 2020 and December 31, 2019, SP Wind had total assets of $2.4 billion and $2.5 billion, respectively, total liabilities of $125 million and $128 million, respectively, and noncontrolling interests of $44 million and $45 million, respectively. Under the terms of the limited liability agreement, distributions without Class A member consent are limited to available cash and SP Wind is obligated to distribute all such available cash to its members each quarter. Available cash includes all cash generated in the quarter subject to the maintenance of appropriate operating reserves. Cash distributions from SP Wind are generally allocated

60%

to Southern Power and

40%

to the three financial investors in accordance with the limited liability agreement.

Southern Power consolidates both SP Solar and SP Wind, as the primary beneficiary, since it controls the most significant activities of each entity, including operating and maintaining their assets. Certain transfers and sales of the assets in the VIEs are subject to partner consent and the liabilities are non-recourse to the general credit of Southern Power. Liabilities consist of customary working capital items and do not include any long-term debt.

Other Variable Interest Entities

Southern Power has other consolidated VIEs that relate to certain subsidiaries that have either sold noncontrolling interests to tax-equity investors or acquired less than a 100% interest from facility developers. These entities are considered VIEs because the arrangements are structured similar to a limited partnership and the noncontrolling members do not have substantive kick-out rights.

At June 30, 2020 and December 31, 2019, the other VIEs had total assets of $1.5 billion and $1.1 billion, respectively, total liabilities of $160 million and $104 million, respectively, and noncontrolling interests of $557 million and $409 million, respectively. Under the terms of the partnership agreements, distributions of all available cash are required each month or quarter and additional distributions require partner consent.

Equity Method Investments

At June 30, 2020 and December 31, 2019, Southern Power had equity method investments in wind and battery storage projects totaling $19 million and $28 million, respectively.

Southern Company Gas

Equity Method Investments

On March 24, 2020, Southern Company Gas completed the sale of its interests in Pivotal LNG and Atlantic Coast Pipeline. See Note (K) under "Southern Company Gas" for additional information.

(a) Does not include Southern Power Company's $120 million and $60 million continuing letter of credit facilities for standby letters of credit expiring in 2021 and 2023, respectively, of which $19 million and $60 million, respectively, was unused at June 30, 2020. Southern Power's subsidiaries are not parties to its bank credit arrangements or letter of credit facilities.
--- ---
(b) Southern Company Gas, as the parent entity, guarantees the obligations of Southern Company Gas Capital, which is the borrower of $1.25 billion of this arrangement. Southern Company Gas' committed credit arrangement also includes $500 million for which Nicor Gas is the borrower and which is restricted for working capital needs of Nicor Gas. Pursuant to this multi-year credit arrangement, the allocations between Southern Company Gas Capital and Nicor Gas may be adjusted.
--- ---

As reflected in the table above, in March 2020, Mississippi Power entered into a $125 million revolving credit facility that matures in March 2023.

Subject to applicable market conditions, Southern Company and its subsidiaries expect to renew or replace their bank credit arrangements as needed, prior to expiration. In connection therewith, Southern Company and its subsidiaries may extend the maturity dates and/or increase or decrease the lending commitments thereunder.

These bank credit arrangements, as well as the term loan arrangements of the Registrants and SEGCO, contain covenants that limit debt levels and contain cross-acceleration or, in the case of Southern Power, cross-default provisions to other indebtedness (including guarantee obligations) that are restricted only to the indebtedness of the individual company. Such cross-default provisions to other indebtedness would trigger an event of default if Southern Power defaulted on indebtedness or guarantee obligations over a specified threshold. Such cross-acceleration provisions to other indebtedness would trigger an event of default if the applicable borrower defaulted on indebtedness, the payment of which was then accelerated. At June 30, 2020, the Registrants, Nicor Gas, and SEGCO were in compliance with all such covenants. None of the bank credit arrangements contain material adverse change clauses at the time of borrowings.

A portion of the unused credit with banks is allocated to provide liquidity support to the revenue bonds of the traditional electric operating companies and the commercial paper programs of the Registrants, Nicor Gas, and SEGCO. The amount of variable rate revenue bonds of the traditional electric operating companies outstanding requiring liquidity support at June 30, 2020 was approximately $1.4 billion (comprised of approximately $854 million at Alabama Power, $550 million at Georgia Power, and $34 million at Mississippi Power). In addition, at June 30, 2020, Georgia Power had approximately $257 million of fixed rate revenue bonds outstanding that are required to be remarketed within the next 12 months.

Earnings per Share

For Southern Company, the only differences in computing basic and diluted earnings per share are attributable to awards outstanding under stock-based compensation plans and, as a result of stock price volatility in the first six months of 2020, the equity units issued in August 2019. Earnings per share dilution resulting from stock-based

(UNAUDITED)

compensation plans and the equity units issuance is determined using the treasury stock method. See Note 8 to the financial statements under "Equity Units" in Item 8 of the Form 10-K for information on the August 2019 equity units issuance and Note 12 to the financial statements in Item 8 of the Form 10-K for information on stock-based compensation plans. Shares used to compute diluted earnings per share were as follows:

Three Months Ended June 30, 2020 Three Months Ended June 30, 2019 Six Months Ended June 30, 2020 Six Months Ended June 30, 2019

Effect of stock-based compensation 5 8 7 8
Effect of equity units 1
Diluted shares 1,063 1,052 1,065 1,049

An immaterial number of stock-based compensation awards was not included in the diluted earnings per share calculation because the awards were anti-dilutive for the three and six months ended June 30, 2020. There were no such amounts for the three and six months ended June 30, 2019.

(G) INCOME TAXES

See Note 10 to the financial statements in Item 8 of the Form 10-K for additional tax information.

Current and Deferred Income Taxes

Tax Credit and Net Operating Loss Carryforwards

The utilization of each Registrants' estimated tax credit and net operating loss carryforwards and related valuation allowances could be impacted by numerous factors, including the acquisition of additional renewable projects, the purchase of rights to additional PTCs of Plant Vogtle Units 3 and 4 pursuant to certain joint ownership agreements, potential impacts of the COVID-19 pandemic, and changes in taxable income projections. See Note (B) and Note 2 to the financial statements in Item 8 of the Form 10-K under "Georgia Power – Nuclear Construction" for additional information on Plant Vogtle Units 3 and 4.

Effective Tax Rate

Details of significant changes in the effective tax rate for the applicable Registrants are provided herein.

Southern Company

Southern Company's effective tax rate is typically lower than the statutory rate due to employee stock plans' dividend deduction, non-taxable AFUDC equity at the traditional electric operating companies, flowback of excess deferred income taxes at the regulated utilities, and federal income tax benefits from ITCs and PTCs primarily at Southern Power.

Southern Company's effective tax rate was

9.3%

for the six months ended June 30, 2020 compared to

33.5%

for the corresponding period in 2019. The effective tax rate decrease was primarily due to the tax impact from the sale of Gulf Power in 2019, as well as an increase in the flowback of excess deferred income taxes in 2020 primarily at Georgia Power. See Note 15 to the financial statements under "Southern Company" in Item 8 of the Form 10-K for additional information.

Georgia Power

Georgia Power's effective tax rate was

4.0%

for the six months ended June 30, 2020 compared to

21.7%

for the corresponding period in 2019. The effective tax rate decrease was primarily due to an increase in the flowback of excess deferred income taxes in 2020 as authorized in the 2019 ARP, as well as the second quarter 2020 charge to

73


Table of Contents                                Index to Financial Statements

(UNAUDITED)

earnings associated with the construction of Plant Vogtle Units 3 and 4. See Note (B) under "Georgia Power – Nuclear Construction" and Note 2 to the financial statements under "Georgia Power" in Item 8 of the Form 10-K for additional information.

Mississippi Power

Mississippi Power's effective tax rate was

10.6%

for the six months ended June 30, 2020 compared to

14.0%

for the corresponding period in 2019. The effective tax rate decrease was primarily due to an increase in the flowback of excess deferred income taxes in 2020 as authorized in the Mississippi Power Rate Case Settlement Agreement. See Note (B) under "Mississippi Power – 2019 Base Rate Case" for additional information.

Southern Power

Southern Power's effective tax rate was

10.5%

for the six months ended June 30, 2020 compared to a benefit rate of

(35.5)%

for the corresponding period in 2019. The effective tax rate increase was primarily due to tax benefits resulting from ITCs recognized upon the sale of Plant Nacogdoches in 2019. See Note (K) under "Southern Power" for additional information.

Southern Company Gas

Southern Company Gas' effective tax rate was

21.5%

for the six months ended June 30, 2020 compared to

18.0%

for the corresponding period in 2019. The effective tax rate increase was primarily due to higher flowback of excess deferred income taxes in 2019, primarily at Atlanta Gas Light as previously authorized by the Georgia PSC, and the reversal of a federal tax valuation allowance in connection with Southern Company Gas' sale of its investment in Triton in 2019. See Notes 2 and 15 to the financial statements under "Southern Company Gas" in Item 8 of the Form 10-K for additional information.

(H) RETIREMENT BENEFITS

The Southern Company system has a qualified defined benefit, trusteed, pension plan covering substantially all employees, with the exception of employees at PowerSecure. The qualified pension plan is funded in accordance with requirements of the Employee Retirement Income Security Act of 1974, as amended (ERISA). No mandatory contributions to the qualified pension plan are anticipated for the year ending December 31, 2020. The Southern Company system also provides certain non-qualified defined benefits for a select group of management and highly compensated employees, which are funded on a cash basis. In addition, the Southern Company system provides certain medical care and life insurance benefits for retired employees through other postretirement benefit plans. The traditional electric operating companies fund other postretirement trusts to the extent required by their respective regulatory commissions. Southern Company Gas has a separate unfunded supplemental retirement health care plan that provides medical care and life insurance benefits to employees of discontinued businesses.

See Note 11 to the financial statements in Item 8 of the Form 10-K for additional information.

Effective January 1, 2020, Southern Company adopted a change in method of calculating the market-related value of the liability-hedging securities included in its pension plan assets. The market-related value is used to determine the expected return on plan assets component of net periodic pension cost. Southern Company previously used the calculated value approach for all plan assets, which smoothed asset returns and deferred gains and losses by amortizing them into the calculation of the market-related value over five years. Southern Company changed to the fair value approach for liability-hedging securities, which includes measuring the market-related value of that portion of the plan assets at fair value for purposes of determining the expected return on plan assets. The remaining asset classes of plan assets will continue to use the calculated value approach in determining the market-related value. Southern Company considers the fair value approach to be preferable because it results in a current reflection of changes in the value of plan assets in the measurement of net periodic pension cost. Southern Company evaluated the effect of this change in accounting method and deemed it immaterial to the historical and current financial statements of all Registrants and therefore did not account for the change retrospectively. The change in accounting principle was recorded through earnings as a prior period adjustment for the amounts related to the unregulated

Table of Contents                                Index to Financial Statements

NOTES TO THE CONDENSED FINANCIAL STATEMENTS (Continued)

(UNAUDITED)

businesses of Southern Company and Southern Power. Amounts related to the traditional electric operating companies and the natural gas distribution utilities have been reflected as adjustments to regulatory assets as appropriate, consistent with the expected regulatory treatment.

On each Registrant's condensed statements of income, the service cost component of net periodic benefit costs is included in other operations and maintenance expenses and all other components of net periodic benefit costs are included in other income (expense), net. Components of the net periodic benefit costs for the three and six months ended June 30, 2020 and 2019 are presented in the following tables.

Valuation Methodologies

The energy-related derivatives primarily consist of exchange-traded and over-the-counter financial products for natural gas and physical power products, including, from time to time, basis swaps. These are standard products used within the energy industry and are valued using the market approach. The inputs used are mainly from observable market sources, such as forward natural gas prices, power prices, implied volatility, and overnight index swap interest rates. Interest rate derivatives are also standard over-the-counter products that are valued using observable market data and assumptions commonly used by market participants. The fair value of interest rate derivatives reflects the net present value of expected payments and receipts under the swap agreement based on the market's expectation of future interest rates. Additional inputs to the net present value calculation may include the contract terms, counterparty credit risk, and occasionally, implied volatility of interest rate options. The fair value of cross-currency swaps reflects the net present value of expected payments and receipts under the swap agreement based on the market's expectation of future foreign currency exchange rates. Additional inputs to the net present value calculation may include the contract terms, counterparty credit risk, and discount rates. The interest rate derivatives and cross-currency swaps are categorized as Level 2 under Fair Value Measurements as these inputs are based on observable data and valuations of similar instruments. See Note (J) for additional information on how these derivatives are used.

For fair value measurements of the investments within the nuclear decommissioning trusts and the non-qualified deferred compensation trusts, external pricing vendors are designated for each asset class with each security specifically assigned a primary pricing source. For investments held within commingled funds, fair value is determined at the end of each business day through the net asset value, which is established by obtaining the underlying securities' individual prices from the primary pricing source. A market price secured from the primary source vendor is then evaluated by management in its valuation of the assets within the trusts. As a general approach, fixed income market pricing vendors gather market data (including indices and market research reports) and integrate relative credit information, observed market movements, and sector news into proprietary pricing models, pricing systems, and mathematical tools. Dealer quotes and other market information, including live trading levels and pricing analysts' judgments, are also obtained when available.

The NRC requires licensees of commissioned nuclear power reactors to establish a plan for providing reasonable assurance of funds for future decommissioning. See Note 6 to the financial statements under "Nuclear Decommissioning" in Item 8 of the Form 10-K for additional information.

Southern Power has contingent payment obligations related to certain acquisitions whereby Southern Power is primarily obligated to make generation-based payments to the seller, which commenced at the commercial operation of the respective facility and continue through 2026. The obligation is categorized as Level 3 under Fair Value Measurements as the fair value is determined using significant unobservable inputs for the forecasted facility generation in MW-hours, as well as other inputs such as a fixed dollar amount per MW-hour, and a discount rate.

81

NOTES TO THE CONDENSED FINANCIAL STATEMENTS (Continued)

(UNAUDITED)

The fair value of contingent consideration reflects the net present value of expected payments and any periodic change arising from forecasted generation is expected to be immaterial.

"Other investments" include investments traded in the open market that have maturities greater than 90 days, which are categorized as Level 2 under Fair Value Measurements and are comprised of corporate bonds, bank certificates of deposit, treasury bonds, and/or agency bonds.

As of June 30, 2020, the fair value measurements of private equity investments held in Alabama Power's nuclear decommissioning trusts that are calculated at net asset value per share (or its equivalent) as a practical expedient totaled $61 million and unfunded commitments related to the private equity investments totaled $72 million. Private equity investments include high-quality private equity funds across several market sectors and funds that invest in real estate assets. Private equity funds do not have redemption rights. Distributions from these funds will be received as the underlying investments in the funds are liquidated.

As of June 30, 2020, other financial instruments for which the carrying amount did not equal fair value were as follows:

The fair values are determined using Level 2 measurements and are based on quoted market prices for the same or similar issues or on the current rates available to the Registrants.

Commodity Contracts with Level 3 Valuation Inputs

As of June 30, 2020, the fair value of Southern Company Gas' Level 3 physical natural gas forward contracts was $80 million. Since commodity contracts classified as Level 3 typically include a combination of observable and unobservable components, the changes in fair value may include amounts due in part to observable market factors, or changes to assumptions on the unobservable components. The following table includes transfers to Level 3, which represent the fair value of Southern Company Gas' commodity derivative contracts that include a significant unobservable component for the first time during the period.

The valuation of certain commodity contracts requires the use of certain unobservable inputs. All forward pricing used in the valuation of such contracts is directly based on third-party market data, such as broker quotes and exchange settlements, when that data is available. If third-party market data is not available, then industry standard methodologies are used to develop inputs that maximize the use of relevant observable inputs and minimize the use of unobservable inputs. Observable inputs, including some forward prices used for determining fair value, reflect the best available market information. Unobservable inputs are updated using industry standard techniques such as extrapolation, combining observable forward inputs supplemented by historical market and other relevant data. Level 3 physical natural gas forward contracts include unobservable forward price inputs (ranging from

$(0.91)

to

$0.99

per mmBtu). Forward price increases (decreases) as of June 30, 2020 would have resulted in higher (lower) values on a net basis.

(J) DERIVATIVES

Southern Company, the traditional electric operating companies, Southern Power, and Southern Company Gas are exposed to market risks, including commodity price risk, interest rate risk, weather risk, and occasionally foreign currency exchange rate risk. To manage the volatility attributable to these exposures, each company nets its exposures, where possible, to take advantage of natural offsets and enters into various derivative transactions for the remaining exposures pursuant to each company's policies in areas such as counterparty exposure and risk management practices. Southern Company Gas' wholesale gas operations use various contracts in its commercial activities that generally meet the definition of derivatives. For the traditional electric operating companies, Southern Power, and Southern Company Gas' other businesses, each company's policy is that derivatives are to be used primarily for hedging purposes and mandates strict adherence to all applicable risk management policies. Derivative positions are monitored using techniques including, but not limited to, market valuation, value at risk, stress testing, and sensitivity analysis. Derivative instruments are recognized at fair value in the balance sheets as either assets or liabilities and are presented on a net basis. See Note (I) for additional fair value information. In the statements of cash flows, any cash impacts of settled energy-related and interest rate derivatives are recorded as operating activities. Any cash impacts of settled foreign currency derivatives are classified as operating or financing activities to correspond with classification of the hedged interest or principal, respectively. See Note 1 to the financial statements under "Financial Instruments" in Item 8 of the Form 10-K for additional information.

Energy-Related Derivatives

The traditional electric operating companies, Southern Power, and Southern Company Gas enter into energy-related derivatives to hedge exposures to electricity, natural gas, and other fuel price changes. However, due to cost-based rate regulations and other various cost recovery mechanisms, the traditional electric operating companies and the natural gas distribution utilities have limited exposure to market volatility in energy-related commodity prices. Each of the traditional electric operating companies and certain of the natural gas distribution utilities of Southern Company Gas manage fuel-hedging programs, implemented per the guidelines of their respective state PSCs or other applicable state regulatory agencies, through the use of financial derivative contracts, which are expected to continue to mitigate price volatility. The traditional electric operating companies (with respect to wholesale generating capacity) and Southern Power have limited exposure to market volatility in energy-related commodity prices because their long-term sales contracts shift substantially all fuel cost responsibility to the purchaser. However, the traditional electric operating companies and Southern Power may be exposed to market volatility in energy-related commodity prices to the extent any uncontracted capacity is used to sell electricity. Southern Company Gas retains exposure to price changes that can, in a volatile energy market, be material and can adversely affect its results of operations.

Southern Company Gas also enters into weather derivative contracts as economic hedges of operating margins in the event of warmer-than-normal weather. Exchange-traded options are carried at fair value, with changes reflected in operating revenues. Non-exchange-traded options are accounted for using the intrinsic value method. Changes in the intrinsic value for non-exchange-traded contracts are reflected in operating revenues.

NOTES TO THE CONDENSED FINANCIAL STATEMENTS (Continued)

(UNAUDITED)

Energy-related derivative contracts are accounted for under one of three methods:

Regulatory Hedges — Energy-related derivative contracts designated as regulatory hedges relate primarily to the traditional electric operating companies' and the natural gas distribution utilities' fuel-hedging programs, where gains and losses are initially recorded as regulatory liabilities and assets, respectively, and then are included in fuel expense as the underlying fuel is used in operations and ultimately recovered through the respective fuel cost recovery clauses.
Cash Flow Hedges — Gains and losses on energy-related derivatives designated as cash flow hedges (which are mainly used to hedge anticipated purchases and sales) are initially deferred in accumulated OCI before being recognized in the statements of income in the same period and in the same income statement line item as the earnings effect of the hedged transactions.
--- ---
Not Designated — Gains and losses on energy-related derivative contracts that are not designated or fail to qualify as hedges are recognized in the statements of income as incurred.
--- ---

Some energy-related derivative contracts require physical delivery as opposed to financial settlement, and this type of derivative is both common and prevalent within the electric and natural gas industries. When an energy-related derivative contract is settled physically, any cumulative unrealized gain or loss is reversed and the contract price is recognized in the respective line item representing the actual price of the underlying goods being delivered.

At June 30, 2020, the net volume of energy-related derivative contracts for natural gas positions, together with the longest hedge date over which the respective entity is hedging its exposure to the variability in future cash flows for forecasted transactions and the longest non-hedge date for derivatives not designated as hedges, were as follows:

Net<br><br>Purchased<br><br>mmBtu Longest<br><br>Hedge<br><br>Date Longest<br><br>Non-Hedge<br><br>Date
(in millions)
Southern Company^(*)^ 944 2024 2031
Alabama Power 85 2024
Georgia Power 152 2023
Mississippi Power 91 2024
Southern Power 15 2022 2021
Southern Company Gas^(*)^ 601 2022 2031
(*) Southern Company Gas' derivative instruments include both long and short natural gas positions. A long position is a contract to purchase natural gas and a short position is a contract to sell natural gas. Southern Company Gas' volume represents the net of long natural gas positions of 4.6 billion mmBtu and short natural gas positions of 4.0 billion mmBtu as of June 30, 2020, which is also included in Southern Company's total volume.
--- ---

At June 30, 2020, the net volume of Southern Power's energy-related derivative contracts for power to be sold was 1 million MWHs, all of which expire in 2020.

In addition to the volumes discussed above, the traditional electric operating companies and Southern Power enter into physical natural gas supply contracts that provide the option to sell back excess natural gas due to operational constraints. The maximum expected volume of natural gas subject to such a feature is 16 million mmBtu for Southern Company, which includes 4 million mmBtu for Alabama Power, 5 million mmBtu for Georgia Power, 2 million mmBtu for Mississippi Power, and 5 million mmBtu for Southern Power.

For cash flow hedges of energy-related derivatives, the estimated pre-tax gains (losses) expected to be reclassified from accumulated OCI to earnings for the 12-month period ending June 30, 2021 are immaterial for all Registrants.

Interest Rate Derivatives

Southern Company and certain subsidiaries may enter into interest rate derivatives to hedge exposure to changes in interest rates. The derivatives employed as hedging instruments are structured to minimize ineffectiveness. Derivatives related to existing variable rate securities or forecasted transactions are accounted for as cash flow hedges where the derivatives' fair value gains or losses are recorded in OCI and are reclassified into earnings at the same time and presented on the same income statement line item as the earnings effect of the hedged transactions. Derivatives related to existing fixed rate securities are accounted for as fair value hedges, where the derivatives' fair value gains or losses and hedged items' fair value gains or losses are both recorded directly to earnings on the same income statement line item. Fair value gains or losses on derivatives that are not designated or fail to qualify as hedges are recognized in the statements of income as incurred.

At June 30, 2020, the following interest rate derivatives were outstanding:

Notional<br><br>Amount Interest<br><br>Rate<br><br>Received Weighted<br><br>Average<br><br>Interest<br><br>Rate Paid Hedge<br><br>Maturity<br><br>Date Fair Value Gain (Loss) at June 30, 2020

Fair Value Hedges of Existing Debt
Southern Company parent 1,500 2.35% 1-month LIBOR + 0.87% July 2021 23
Southern Company $ 1,760 $

The estimated pre-tax gains (losses) related to interest rate derivatives expected to be reclassified from accumulated OCI to interest expense for the 12-month period ending June 30, 2021 total $(25) million for Southern Company and are immaterial for all other Registrants. Deferred gains and losses related to interest rate derivatives are expected to be amortized into earnings through 2046 for the Southern Company parent entity, 2035 for Alabama Power, 2044 for Georgia Power, 2028 for Mississippi Power, and 2046 for Southern Company Gas.

Foreign Currency Derivatives

Southern Company and certain subsidiaries, including Southern Power, may enter into foreign currency derivatives to hedge exposure to changes in foreign currency exchange rates, such as that arising from the issuance of debt denominated in a currency other than U.S. dollars. Derivatives related to forecasted transactions are accounted for as cash flow hedges where the derivatives' fair value gains or losses are recorded in OCI and are reclassified into earnings at the same time and on the same income statement line as the earnings effect of the hedged transactions, including foreign currency gains or losses arising from changes in the U.S. currency exchange rates. The derivatives employed as hedging instruments are structured to minimize ineffectiveness.

Derivative Financial Statement Presentation and Amounts

Southern Company, the traditional electric operating companies, Southern Power, and Southern Company Gas enter into derivative contracts that may contain certain provisions that permit intra-contract netting of derivative receivables and payables for routine billing and offsets related to events of default and settlements. Southern Company and certain subsidiaries also utilize master netting agreements to mitigate exposure to counterparty credit risk. These agreements may contain provisions that permit netting across product lines and against cash collateral. The fair value amounts of derivative assets and liabilities on the balance sheet are presented net to the extent that there are netting arrangements or similar agreements with the counterparties.

For the three and six months ended June 30, 2020 and 2019, the pre-tax effects of energy-related derivatives and interest rate derivatives not designated as hedging instruments were immaterial for all other Registrants.

Contingent Features

Southern Company, the traditional electric operating companies, Southern Power, and Southern Company Gas do not have any credit arrangements that would require material changes in payment schedules or terminations as a result of a credit rating downgrade. There are certain derivatives that could require collateral, but not accelerated payment, in the event of various credit rating changes of certain Southern Company subsidiaries. At June 30, 2020, the Registrants had no collateral posted with derivative counterparties to satisfy these arrangements.

For the Registrants with interest rate derivatives at June 30, 2020, the fair value of interest rate derivative liabilities with contingent features and the maximum potential collateral requirements arising from the credit-risk-related contingent features, at a rating below BBB- and/or Baa3, was immaterial. At June 30, 2020, the fair value of energy-related derivative liabilities with contingent features and the maximum potential collateral requirements arising from the credit-risk-related contingent features, at a rating below BBB- and/or Baa3, were immaterial for all Registrants. The maximum potential collateral requirements arising from the credit-risk-related contingent features for the traditional electric operating companies and Southern Power include certain agreements that could require collateral in the event that one or more Southern Company power pool participants has a credit rating change to below investment grade. Following the sale of Gulf Power to NextEra Energy, Gulf Power is continuing to participate in the Southern Company power pool for a defined transition period that, subject to certain potential adjustments, is scheduled to end on January 1, 2024.

(UNAUDITED)

Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash. If collateral is required, fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral are not offset against fair value amounts recognized for derivatives executed with the same counterparty.

Alabama Power and Southern Power maintain accounts with certain regional transmission organizations to facilitate financial derivative transactions. Based on the value of the positions in these accounts and the associated margin requirements, Alabama Power and Southern Power may be required to post collateral. At June 30, 2020, cash collateral posted in these accounts was immaterial. Southern Company Gas maintains accounts with brokers or the clearing houses of certain exchanges to facilitate financial derivative transactions. Based on the value of the positions in these accounts and the associated margin requirements, Southern Company Gas may be required to deposit cash into these accounts. At June 30, 2020, cash collateral held on deposit in broker margin accounts was $114 million.

The Registrants are exposed to losses related to financial instruments in the event of counterparties' nonperformance. The Registrants only enter into agreements and material transactions with counterparties that have investment grade credit ratings by Moody's and S&P or with counterparties who have posted collateral to cover potential credit exposure. The Registrants have also established risk management policies and controls to determine and monitor the creditworthiness of counterparties in order to mitigate their exposure to counterparty credit risk. Prior to entering into a physical transaction, Southern Company Gas assigns physical wholesale counterparties an internal credit rating and credit limit based on the counterparties' Moody's, S&P, and Fitch ratings, commercially available credit reports, and audited financial statements. Southern Company Gas may require counterparties to pledge additional collateral when deemed necessary.

In addition, Southern Company Gas conducts credit evaluations and obtains appropriate internal approvals for the counterparty's line of credit before any transaction with the counterparty is executed. In most cases, the counterparty must have an investment grade rating, which includes a minimum long-term debt rating of Baa3 from Moody's and BBB- from S&P. Generally, Southern Company Gas requires credit enhancements by way of a guaranty, cash deposit, or letter of credit for transaction counterparties that do not have investment grade ratings.

Southern Company Gas also utilizes master netting agreements whenever possible to mitigate exposure to counterparty credit risk. When Southern Company Gas is engaged in more than one outstanding derivative transaction with the same counterparty and it also has a legally enforceable netting agreement with that counterparty, the "net" mark-to-market exposure represents the netting of the positive and negative exposures with that counterparty and a reasonable measure of Southern Company Gas' credit risk. Southern Company Gas also uses other netting agreements with certain counterparties with whom it conducts significant transactions. Master netting agreements enable Southern Company Gas to net certain assets and liabilities by counterparty. Southern Company Gas also nets across product lines and against cash collateral provided the master netting and cash collateral agreements include such provisions. Southern Company Gas may require counterparties to pledge additional collateral when deemed necessary.

The Registrants do not anticipate a material adverse effect on their respective financial statements as a result of counterparty nonperformance.

(K) ACQUISITIONS AND DISPOSITIONS

See Note 15 to the financial statements in Item 8 of the Form 10-K for additional information, including details of assets and liabilities held for sale at December 31, 2019 for Southern Company, Southern Power, and Southern Company Gas. The Registrants had no material assets or liabilities held for sale at June 30, 2020.

Alabama Power

On April 22, 2020 and June 9, 2020, the FERC and the Alabama PSC, respectively, approved the Autauga Combined Cycle Acquisition, which is expected to close by September 1, 2020.

--- ---

In March 2020, Southern Power entered into an agreement to acquire a controlling membership interest in an approximately

300

-MW wind facility located in South Dakota. The acquisition is subject to FERC approval and certain other customary conditions to closing, including commercial operation of the facility, which is expected to occur in late 2020 or early 2021. The facility's output is contracted under two long-term PPAs. The ultimate outcome of this matter cannot be determined at this time.

Construction Projects

During the six months ended June 30, 2020, Southern Power completed construction of and placed in service the Reading wind facility, continued construction of the Skookumchuck wind facility, and commenced construction of the Garland and Tranquillity battery energy storage facilities. Total aggregate construction costs, excluding acquisition costs, are expected to be between $475 million and $545 million for the facilities under construction. At June 30, 2020, total costs of construction incurred for these projects were $232 million and are included in CWIP. The ultimate outcome of these matters cannot be determined at this time.

(a) In 2018, Southern Power purchased 100% of the membership interests of the Reading facility pursuant to a joint development arrangement. At the time the facility was placed in service, Southern Power recorded an operating lease right-of-use asset and an operating lease liability, each in the amount of $24 million. In June 2020, Southern Power completed a tax equity transaction whereby it received $156 million and now owns 100% of the Class B membership interests.
--- ---
(b) In October 2019, Southern Power purchased 100% of the membership interests of the Skookumchuck facility pursuant to a joint development arrangement. Southern Power expects to complete a tax equity transaction upon commercial operation and retain the Class B membership interests. Shortly after commercial operation, Southern Power may sell a noncontrolling interest in these Class B membership interests to another partner. The ultimate outcome of these matters cannot be determined at this time.
--- ---
(c) Prior to commercial operation, Southern Power may enter into one or more partnerships, in which case it would ultimately own less than 100% of the Class B membership interests, but would retain ownership of the controlling interest. The PPAs for these facilities are pending approval from the California Public Utilities Commission. The ultimate outcome of these matters cannot be determined at this time.

Southern Power continues to evaluate and refine the deployment of the remaining wind turbine equipment purchased in 2016 and 2017 to development and construction projects. During the six months ended June 30, 2020, certain wind turbine equipment was sold, resulting in an immaterial gain.

Sales of Natural Gas and Biomass Plants

On January 17, 2020, Southern Power completed the sale of its equity interests in Plant Mankato (including the

385

-MW expansion unit completed in May 2019) to a subsidiary of Xcel for a purchase price of approximately $663 million, including final working capital adjustments. The sale resulted in a gain of approximately $39 million ($23 million after tax). The assets and liabilities of Plant Mankato were classified as held for sale on Southern Company's and Southern Power's balance sheets at December 31, 2019.

Plants Nacogdoches (sold in June 2019) and Mankato represented individually significant components of Southern Power; therefore, pre-tax income for these components for the three months ended June 30, 2019 and the six months ended June 30, 2020 and 2019 is presented below:

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

OVERVIEW

Southern Company is a holding company that owns all of the common stock of three traditional electric operating companies (Alabama Power, Georgia Power, and Mississippi Power), as well as Southern Power and Southern Company Gas, and owns other direct and indirect subsidiaries. The primary businesses of the Southern Company system are electricity sales by the traditional electric operating companies and Southern Power and the distribution of natural gas by Southern Company Gas. Southern Company's reportable segments are the sale of electricity by the traditional electric operating companies, the sale of electricity in the competitive wholesale market by Southern Power, and the sale of natural gas and other complementary products and services by Southern Company Gas. Southern Company Gas' reportable segments are gas distribution operations, gas pipeline investments, wholesale gas services, and gas marketing services. See Note (L) to the Condensed Financial Statements herein for additional information on segment reporting. For additional information on the Registrants' primary business activities, see BUSINESS – "The Southern Company System" in Item 1 of the Form 10-K.

The Registrants continue to focus on several key performance indicators. For the traditional electric operating companies and Southern Company Gas, these indicators include, but are not limited to, customer satisfaction, plant availability, electric and natural gas system reliability, and execution of major construction projects. For Southern Power, these indicators include, but are not limited to, the equivalent forced outage rate and contract availability to evaluate operating results and help ensure its ability to meet its contractual commitments to customers. In addition, Southern Company and the Subsidiary Registrants focus on earnings per share and net income, respectively, as a key performance indicator.

Recent Developments

COVID-19

During March 2020, COVID-19 was declared a pandemic by the World Health Organization and the Centers for Disease Control and Prevention and has spread globally, including throughout the United States. The Southern Company system provides a critical service to its customers; therefore, it is essential that Southern Company system employees are able to continue to perform their critical duties safely and effectively. The Southern Company system has implemented applicable business continuity plans, including teleworking, canceling non-essential business travel, increasing cleaning frequency at business locations, implementing applicable safety and health guidelines issued by federal and state officials, and establishing protocols for required work on customer premises. To date, these procedures have been effective in maintaining the Southern Company system's critical operations. As a result of the COVID-19 pandemic, there have been economic disruptions in the Registrants' operating territories. The traditional electric operating companies and the natural gas distribution utilities temporarily suspended disconnections for non-payment by customers and waived late fees for certain periods. See FUTURE EARNINGS POTENTIAL – "Regulatory Matters" herein for information regarding deferral of certain incremental COVID-19-related costs, including bad debt, to a regulatory asset by certain of the traditional electric operating companies and the natural gas distribution utilities. In addition, the COVID-19 pandemic has resulted in a reduction in workforce at Plant Vogtle Units 3 and 4, as discussed further herein. Additional information regarding COVID-19 and its potential impacts on the Registrants is provided throughout Management's Discussion and Analysis of Financial Condition and Results of Operations and in Item 1A herein.

Alabama Power

On June 9, 2020, the Alabama PSC approved in part Alabama Power's petition for a certificate of convenience and necessity (CCN) filed in September 2019 to procure additional capacity. See FUTURE EARNINGS POTENTIAL – "Regulatory Matters – Alabama Power" herein for additional information.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

Georgia Power

Plant Vogtle Units 3 and 4 Status

In 2009, the Georgia PSC certified construction of Plant Vogtle Units 3 and 4 (with electric generating capacity of approximately 1,100 MWs each), in which Georgia Power holds a 45.7% ownership interest.

During the second quarter 2020, approximately $194 million of construction contingency was assigned to the base capital cost forecast, which exceeded the remaining balance of the construction contingency originally established in the second quarter 2018. As a result, Southern Nuclear recommended establishing additional construction contingency, of which Georgia Power's share is $115 million, for potential risks including, among other factors, construction productivity and expected impacts of the COVID-19 pandemic; adding resources for supervision, field support, project management, initial test program, start-up, and operations and engineering support; subcontracts; and procurement.

After considering the significant level of uncertainty that exists regarding the future recoverability of these costs since the ultimate outcome of these matters is subject to the outcome of future assessments by management, as well as Georgia PSC decisions in future regulatory proceedings, Georgia Power recorded a total pre-tax charge to income of $149 million ($111 million after tax) for the increase in the total project capital cost forecast as of June 30, 2020. As and when these amounts are spent, Georgia Power may request the Georgia PSC to evaluate those expenditures for rate recovery.

In mid-March 2020, Southern Nuclear began implementing policies and procedures designed to mitigate the risk of transmission of COVID-19 at the construction site. In April 2020, Georgia Power, acting for itself and as agent for the other Vogtle Owners, announced a reduction in workforce at Plant Vogtle Units 3 and 4, which totaled approximately 20% of the then-existing site workforce. This workforce reduction lowered absenteeism, providing an improvement in operational efficiency and allowing for increased social distancing. From the initial peak in April 2020, the number of active cases at the site declined significantly during May and early June, but began increasing again in mid-June and continues to impact productivity levels and pace of activity completion. As a result, overall production improvements have not been achieved at the levels anticipated, contributing to the allocation of, and increase in, construction contingency described above.

To address these issues, in July 2020, Southern Nuclear updated its aggressive site work plan for both Unit 3 and Unit 4. While Southern Nuclear's July 2020 aggressive site work plan extended milestone dates from its February 2020 aggressive site work plan, Georgia Power still expects to achieve the regulatory-approved in-service dates of November 2021 and November 2022 for Plant Vogtle Units 3 and 4, respectively.

The continuing effects of the COVID-19 pandemic could further disrupt or delay construction, testing, supervisory, and support activities at Plant Vogtle Units 3 and 4. Georgia Power's proportionate share of the estimated incremental cost associated with COVID-19 mitigation actions and impacts on construction productivity is currently estimated to be between $70 million and $115 million. However, the ultimate impact of the COVID-19 pandemic on the construction schedule and budget for Plant Vogtle Units 3 and 4 cannot be determined at this time.

See FUTURE EARNINGS POTENTIAL – "Construction Programs – Nuclear Construction" herein for additional information.

Mississippi Power

On March 17, 2020, the Mississippi PSC approved a settlement agreement between Mississippi Power and the Mississippi Public Utilities Staff related to Mississippi Power's base rate case filed in November 2019 (Mississippi Power Rate Case Settlement Agreement). Under the terms of the Mississippi Power Rate Case Settlement Agreement, annual retail rates decreased approximately $16.7 million, or 1.85%, effective for the first billing cycle of April 2020. See FUTURE EARNINGS POTENTIAL – "Regulatory Matters – Mississippi Power – 2019 Base Rate Case" herein for additional information.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

Southern Power

During the six months ended June 30, 2020, Southern Power completed construction of and placed in service the 200-MW Reading wind facility, continued construction of the 136-MW Skookumchuck wind facility, and commenced construction of the Garland and Tranquillity battery energy storage facilities. See FUTURE EARNINGS POTENTIAL – "Construction Programs – Southern Power" herein for additional information.

On January 17, 2020, Southern Power completed the sale of its equity interests in Plant Mankato (including the 385-MW expansion unit completed in May 2019) to a subsidiary of Xcel for a purchase price of approximately $663 million, including final working capital adjustments.

In March 2020, Southern Power entered into an agreement to acquire a controlling membership interest in an approximately 300-MW wind facility located in South Dakota. The acquisition is subject to FERC approval and certain other customary conditions to closing, including commercial operation of the facility, which is expected to occur in late 2020 or early 2021. The facility's output is contracted under two long-term PPAs. The ultimate outcome of this matter cannot be determined at this time.

On May 1, 2020, Southern Power purchased a controlling interest in the 56-MW Beech Ridge II wind facility located in Greenbrier County, West Virginia from Invenergy Renewables LLC. The facility's output is contracted under a 12-year PPA. See Note (K) to the Condensed Financial Statements herein for additional information.

At June 30, 2020, Southern Power's average investment coverage ratio for its generating assets, including those owned with various partners, based on the ratio of investment under contract to total investment using the respective generation facilities' net book value (or expected in-service value for facilities under construction) as the investment amount was 94% through 2024 and 92% through 2029, with an average remaining contract duration of approximately 14 years.

Southern Company Gas

On March 24, 2020, Southern Company Gas completed the sale of its interests in Pivotal LNG and Atlantic Coast Pipeline with aggregate proceeds of $178 million, including working capital adjustments. See Note (K) to the Condensed Financial Statements under "Southern Company Gas" herein for additional information.

On June 1, 2020, Virginia Natural Gas filed a general rate case with the Virginia Commission seeking an increase in rates of approximately $49.6 million based on a ROE of 10.35% and an equity ratio of 54%. The Virginia Commission is expected to rule on the requested increase in the second quarter 2021.

On July 1, 2020, Atlanta Gas Light filed its 2020 GRAM filing with the Georgia PSC requesting an increase in annual base rates of $37.6 million. Resolution of the 2020 GRAM filing is expected by December 31, 2020, with rates effective January 1, 2021.

See FUTURE EARNINGS POTENTIAL – "Regulatory Matters – Southern Company Gas" herein for additional information regarding Southern Company Gas' regulatory filings. The ultimate outcome of these matters cannot be determined at this time.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

primarily due to decreases in retail revenues associated with milder weather and lower customer usage in the second quarter 2020 compared to the corresponding period in 2019, a $111 million after-tax charge in the second quarter 2020 related to Georgia Power's construction of Plant Vogtle Units 3 and 4, an $88 million after-tax gain on the sale of Plant Nacogdoches in the second quarter 2019, higher depreciation and amortization, and a $74 million after-tax leveraged lease impairment in the second quarter 2020. These decreases to net income were partially offset by increases in retail revenues associated with rates and pricing and lower other operations and maintenance expenses. See Note 15 to the financial statements under "Southern Power" in Item 8 of the Form 10-K for additional information regarding the disposition of Plant Nacogdoches, Note (B) to the Condensed Financial Statements under "Georgia Power – Nuclear Construction" herein for additional information on the construction of Plant Vogtle Units 3 and 4, and Note (C) to the Condensed Financial Statements under "Other Matters – Southern Company" herein for additional information on the leveraged lease impairment.

Consolidated net income attributable to Southern Company was $1.5 billion ($1.40 per share) for year-to-date 2020 compared to $3.0 billion ($2.86 per share) for the corresponding period in 2019. The decrease was primarily due to the $2.5 billion ($1.3 billion after tax) gain on the sale of Gulf Power recorded in 2019. See Note 15 to the financial statements under "Southern Company" in Item 8 of the Form 10-K for additional information regarding the sale of Gulf Power.

(change in millions) (% change) (change in millions) (% change)
$(358) (10.1) $(363) (5.5)

In the second quarter 2020, retail electric revenues were $3.2 billion compared to $3.5 billion for the corresponding period in 2019. For year-to-date 2020, retail electric revenues were $6.3 billion compared to $6.6 billion for the corresponding period in 2019.

Details of the changes in retail electric revenues were as follows:

Second Quarter 2020 Year-to-Date 2020
(in millions) (% change) (in millions) (% change)
Retail electric – prior year $ 3,540 $ 6,623
Estimated change resulting from –
Rates and pricing 124 3.5 % 267 4.0 %
Sales decline (107 ) (3.0 ) (99 ) (1.5 )
Weather (132 ) (3.7 ) (159 ) (2.4 )
Fuel and other cost recovery (243 ) (6.9 ) (372 ) (5.6 )
Retail electric – current year $ 3,182 (10.1 )% $ 6,260 (5.5 )%

Revenues associated with changes in rates and pricing increased in the second quarter and year-to-date 2020 when compared to the corresponding periods in 2019 primarily due to an increase in revenue at Georgia Power and Alabama Power related to the recovery of environmental compliance costs and Rate CNP Compliance costs, respectively, as well as the impacts of Georgia Power accruals for customer refunds in the first quarter and year-to-date 2019 related to Tax Reform and the rate pricing effects of decreased customer usage at Georgia Power. Partially offsetting these increases were lower contributions from commercial and industrial customers with variable demand-driven pricing at Georgia Power. Additionally, the year-to-date increase was due to Alabama Power customer bill credits in the first quarter 2019 related to Tax Reform. See Note 2 to the financial statements under "Alabama Power" and "Georgia Power" in Item 8 of the Form 10-K and Note (B) to the Condensed Financial Statements herein for additional information.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

Revenues attributable to changes in sales decreased in the second quarter and year-to-date 2020 when compared to the corresponding periods in 2019 largely due to social distancing and shelter-in-place guidelines related to the COVID-19 pandemic. Weather-adjusted residential KWH sales increased 4.7% and 3.8% in the second quarter and year-to-date 2020, respectively, when compared to the corresponding periods in 2019 primarily due to customer growth and an increase in average customer usage, primarily due to the temporary suspension of customer disconnections for nonpayment and shelter-in-place orders. Weather-adjusted commercial KWH sales decreased 11.5% and 6.3% in the second quarter and year-to-date 2020, respectively, when compared to the corresponding periods in 2019 primarily due to lower customer usage resulting from shelter-in-place orders and restrictions on business operations in response to the COVID-19 pandemic. Industrial KWH sales decreased 14.0% and 8.0% in the second quarter and year-to-date 2020, respectively, when compared to the corresponding periods in 2019 as a result of disruptions in supply chain and business operations related to the COVID-19 pandemic and the overall decrease in business activity due to the resulting recession.

Fuel and other cost recovery revenues decreased $243 million and $372 million in the second quarter and year-to-date 2020, respectively, compared to the corresponding periods in 2019 primarily due to decreases in generation and the average cost of fuel and purchased power. Electric rates for the traditional electric operating companies include provisions to adjust billings for fluctuations in fuel costs, including the energy component of purchased power costs. Under these provisions, fuel revenues generally equal fuel expenses, including the energy component of PPA costs, and do not affect net income. The traditional electric operating companies each have one or more regulatory mechanisms to recover other costs such as environmental and other compliance costs, storm damage, new plants, and PPA capacity costs.

Wholesale Electric Revenues

Second Quarter 2020 vs. Second Quarter 2019 Year-to-Date 2020 vs. Year-to-Date 2019
(change in millions) (% change) (change in millions) (% change)
$(70) (12.9) $(152) (14.6)

Wholesale electric revenues consist of revenues from PPAs and short-term opportunity sales. Wholesale electric revenues from PPAs (other than solar and wind PPAs) have both capacity and energy components. Capacity revenues generally represent the greatest contribution to net income and are designed to provide recovery of fixed costs plus a return on investment. Energy revenues will vary depending on fuel prices, the market prices of wholesale energy compared to the Southern Company system's generation, demand for energy within the Southern Company system's electric service territory, and the availability of the Southern Company system's generation. Increases and decreases in energy revenues that are driven by fuel prices are accompanied by an increase or decrease in fuel costs and do not have a significant impact on net income. Energy sales from solar and wind PPAs do not have a capacity charge and customers either purchase the energy output of a dedicated renewable facility through an energy charge or through a fixed price related to the energy. As a result, the ability to recover fixed and variable operations and maintenance expenses is dependent upon the level of energy generated from these facilities, which can be impacted by weather conditions, equipment performance, transmission constraints, and other factors. Wholesale electric revenues at Mississippi Power include FERC-regulated municipal and rural association sales under cost-based tariffs as well as market-based sales. Short-term opportunity sales are made at market-based rates that generally provide a margin above the Southern Company system's variable cost to produce the energy.

In the second quarter 2020, wholesale electric revenues were $472 million compared to $542 million for the corresponding period in 2019. For year-to-date 2020, wholesale electric revenues were $889 million compared to $1.0 billion for the corresponding period in 2019. These decreases reflect decreases of $46 million and $103 million in energy revenues for the second quarter and year-to-date 2020, respectively, and $24 million and $49 million in capacity revenues for the second quarter and year-to-date 2020, respectively. The decreases in energy revenues include $24 million and $67 million for the second quarter and year-to-date 2020, respectively, from Southern Power, with the remainder from the traditional electric operating companies. These decreases primarily result from lower natural gas prices and a net decrease in the volume of KWHs sold, primarily as a result of milder weather in

AND RESULTS OF OPERATIONS (Continued)

the Southeast U.S. when compared to the corresponding periods in 2019. The decrease in capacity revenues was primarily related to Southern Power's sales of Plant Nacogdoches in the second quarter 2019 and Plant Mankato in the first quarter 2020. See Note (K) to the Condensed Financial Statements under "Southern Power" herein and Note 15 to the financial statements under "Southern Power – Sales of Natural Gas and Biomass Plants" in Item 8 of the Form 10-K for additional information.

Natural Gas Revenues

Second Quarter 2020 vs. Second Quarter 2019 Year-to-Date 2020 vs. Year-to-Date 2019
(change in millions) (% change) (change in millions) (% change)
$(53) (7.7) $(278) (12.9)

In the second quarter 2020, natural gas revenues were $636 million compared to $689 million for the corresponding period in 2019. For year-to-date 2020, natural gas revenues were $1.9 billion compared to $2.2 billion for the corresponding period in 2019.

Details of the changes in natural gas revenues were as follows:

Second Quarter 2020 Year-to-Date 2020
(in millions) (% change) (in millions) (% change)
Natural gas revenues – prior year $ 689 $ 2,163
Estimated change resulting from –
Infrastructure replacement programs and base rate changes 43 6.2 % 119 5.5 %
Gas costs and other cost recovery (38 ) (5.5 ) (287 ) (13.3 )
Weather 3 0.4 (8 ) (0.4 )
Wholesale gas services (67 ) (9.7 ) (102 ) (4.7 )
Other 6 0.9
Natural gas revenues – current year $ 636 (7.7 )% $ 1,885 (12.9 )%

Revenues attributable to infrastructure replacement programs and base rate changes at the natural gas distribution utilities increased in the second quarter and year-to-date 2020 compared to the corresponding periods in 2019 primarily due to base rate increases at Nicor Gas and Atlanta Gas Light and continued investments recovered through infrastructure replacement programs. See Note 2 to the financial statements under "Southern Company Gas – Rate Proceedings" in Item 8 of the Form 10-K for additional information.

Revenues attributable to gas costs and other cost recovery decreased in the second quarter and year-to-date 2020 compared to the corresponding periods in 2019 primarily due to lower natural gas prices and decreased volumes of natural gas sold. Natural gas distribution rates include provisions to adjust billings for fluctuations in natural gas costs. Therefore, gas costs recovered through natural gas revenues generally equal the amount expensed in cost of natural gas and do not affect net income from the natural gas distribution utilities.

Revenues attributable to Southern Company Gas' wholesale gas services business decreased in the second quarter and year-to-date 2020 compared to the corresponding periods in 2019 primarily due to decreased commercial activity as a result of warmer weather and a decrease in derivative gains.

In the second quarter 2020, other revenues were $162 million compared to $166 million for the corresponding period in 2019. For year-to-date 2020, other revenues were $284 million compared to $352 million for the corresponding period in 2019. These decreases primarily relate to changes in PowerSecure's business, including the sale of its utility infrastructure services business in June 2019 and the wind-down of a segment of its distributed infrastructure business in the first quarter 2020, partially offset by unregulated sales at Georgia Power largely associated with power delivery construction and maintenance contracts. See Note 15 to the financial statements under "Southern Company" in Item 8 of the Form 10-K for additional information.

Fuel and Purchased Power Expenses

Second Quarter 2020 vs. Second Quarter 2019 Year-to-Date 2020 vs. Year-to-Date 2019
(change in millions) (% change) (change in millions) (% change)

Purchased power (1 ) (0.5) 10 2.7
Total fuel and purchased power expenses $ (294 ) $ (497 )

In the second quarter 2020, total fuel and purchased power expenses were $0.8 billion compared to $1.1 billion for the corresponding period in 2019. The decrease was primarily the result of a $118 million decrease in the average cost of fuel and purchased power and a $176 million net decrease in the volume of KWHs generated and purchased.

For year-to-date 2020, total fuel and purchased power expenses were $1.6 billion compared to $2.1 billion for the corresponding period in 2019. The decrease was primarily the result of a $285 million decrease in the average cost of fuel and purchased power and a $212 million net decrease in the volume of KWHs generated and purchased.

Fuel and purchased power energy transactions at the traditional electric operating companies are generally offset by fuel revenues and do not have a significant impact on net income. See FUTURE EARNINGS POTENTIAL – "Regulatory Matters" herein for additional information. Fuel expenses incurred under Southern Power's PPAs are generally the responsibility of the counterparties and do not significantly impact net income.

Fuel

In the second quarter 2020, fuel expense was $621 million compared to $914 million for the corresponding period in 2019. The decrease was primarily due to a 49.3% decrease in the volume of KWHs generated by coal, a 20.9% decrease in the average cost of natural gas per KWH generated, a 2.6% decrease in the average cost of coal per KWH generated, and a 5.2% decrease in the volume of KWHs generated by natural gas.

For year-to-date 2020, fuel expense was $1.3 billion compared to $1.8 billion for the corresponding period in 2019. The decrease was primarily due to a 44.1% decrease in the volume of KWHs generated by coal, a 22.3% decrease in the average cost of natural gas per KWH generated, a 2.0% decrease in the average cost of coal per KWH generated, and a 0.5% decrease in the volume of KWHs generated by natural gas.

Excluding Atlanta Gas Light, which does not sell natural gas to end-use customers, natural gas distribution rates include provisions to adjust billings for fluctuations in natural gas costs. Therefore, gas costs recovered through natural gas revenues generally equal the amount expensed in cost of natural gas and do not affect net income from the natural gas distribution utilities. Cost of natural gas at the natural gas distribution utilities represented 86% of total cost of natural gas for both the second quarter and year-to-date 2020.

In the second quarter 2020, cost of natural gas was $144 million compared to $191 million for the corresponding period in 2019. The decrease reflects a 34.9% decrease in natural gas prices in the second quarter 2020 compared to the corresponding period in 2019.

For year-to-date 2020, cost of natural gas was $583 million compared to $877 million for the corresponding period in 2019. The decrease reflects a 36.6% decrease in natural gas prices compared to 2019 and decreased volumes primarily as a result of warmer weather, as determined by Heating Degree Days, for year-to-date 2020 compared to the corresponding period in 2019.

In the second quarter 2020, cost of other sales was $74 million compared to $84 million for the corresponding period in 2019. For year-to-date 2020, cost of other sales was $129 million compared to $203 million for the corresponding period in 2019. These decreases primarily relate to changes in PowerSecure's business, including the sale of its utility infrastructure services business in June 2019 and the wind-down of a segment of its distributed infrastructure business in the first quarter 2020, partially offset by an increase in expenses related to unregulated sales at Georgia Power largely associated with power delivery construction and maintenance contracts.

$(117) (8.9) $(136) (5.2)

In the second quarter 2020, other operations and maintenance expenses were $1.2 billion compared to $1.3 billion for the corresponding period in 2019. The decrease reflects the impacts of cost containment activities implemented in 2020 to help offset the effects of the recessionary economy resulting from the COVID-19 pandemic, as well as a $32 million goodwill impairment charge in the second quarter 2019 associated with the sale of PowerSecure's utility infrastructure services business unit. The decrease primarily results from decreases of $82 million in scheduled generation outage and maintenance expenses and $17 million in compliance and environmental expenses at the traditional electric operating companies. The decrease also reflects decreases of $14 million in transmission and distribution maintenance expenses, primarily at Alabama Power and Georgia Power, including $11 million of reliability NDR credits at Alabama Power, partially offset by a $46 million increase in storm damage recovery at Georgia Power as authorized in its 2019 ARP.

For year-to-date 2020, other operations and maintenance expenses were $2.5 billion compared to $2.6 billion for the corresponding period in 2019. The decrease reflects the impacts of cost containment activities implemented in 2020 to help offset the effects of the recessionary economy resulting from the COVID-19 pandemic, as well as a $32 million goodwill impairment charge in the second quarter 2019 associated with the sale of PowerSecure's utility infrastructure services business unit. The decrease primarily results from decreases of $111 million in scheduled generation outage and maintenance expenses and $42 million in transmission and distribution expenses at the traditional electric operating companies, including $22 million of reliability NDR credits at Alabama Power, partially offset by a $92 million increase in storm damage recovery at Georgia Power as authorized in its 2019 ARP.

For year-to-date 2020, income taxes were $150 million compared to $1.5 billion for the corresponding period in 2019. The second quarter 2020 decrease was primarily due to the tax impacts of charges associated with a leveraged lease impairment and the construction of Plant Vogtle Units 3 and 4, as well as the flowback of excess deferred income taxes in 2020 as authorized in Georgia Power's 2019 ARP, partially offset by ITCs recognized upon Southern Power's sale of Plant Nacogdoches in the second quarter 2019. The year-to-date 2020 decrease also reflects the tax impacts of the sale of Gulf Power in 2019.

Alabama Power's net income after dividends on preferred stock for the second quarter 2020 was $298 million compared to $296 million for the corresponding period in 2019. This increase was primarily due to a decrease in operations and maintenance expenses and an increase in Rate CNP Compliance-related revenues associated with increased capital investments. These increases to income were partially offset by decreases in retail revenues associated with milder weather in the second quarter 2020 compared to the same period in 2019 and lower customer usage.

Alabama Power's net income after dividends on preferred stock for year-to-date 2020 was $578 million compared to $513 million for the corresponding period in 2019. This increase was primarily due to a decrease in operations and maintenance expenses and an increase in retail revenues associated with the impact of customer bill credits issued in 2019 related to Tax Reform. These increases to income were partially offset by decreases in retail revenues associated with milder weather in the first and second quarters 2020 compared to the same periods in 2019 and lower customer usage. See Note 2 to the financial statements under "Alabama Power – Rate RSE" in Item 8 of the Form 10-K for additional information.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

Rate CNP Compliance-related revenue. The year-to-date increase was primarily due to customer bill credits issued in the first quarter 2019 related to Tax Reform and Rate CNP Compliance-related revenue.

Revenues attributable to changes in sales decreased in the second quarter and year-to-date 2020 when compared to the corresponding periods in 2019 largely due to social distancing and shelter-in-place guidelines related to the COVID-19 pandemic. Weather-adjusted residential KWH sales increased 4.6% and 3.5% in the second quarter and year-to-date 2020, respectively, when compared to the corresponding periods in 2019 primarily due to customer growth and an increase in average customer usage as a result of shelter-in-place orders and the temporary suspension of customer disconnections. Weather-adjusted commercial KWH sales decreased 12.2% and 7.3% in the second quarter and year-to-date 2020, respectively, when compared to the corresponding periods in 2019 primarily due to lower customer usage resulting from shelter-in-place orders and restrictions on business operations in response to the COVID-19 pandemic. Industrial KWH sales decreased 15.5% and 8.7% in the second quarter and year-to-date 2020, respectively, when compared to the corresponding periods in 2019 as a result of disruptions in supply chain and business operations driven by the COVID-19 pandemic and the overall decrease in business activity due to the resulting recession.

Fuel and other cost recovery revenues decreased in the second quarter and year-to-date 2020 when compared to the corresponding periods in 2019 primarily due to decreases in generation and the average cost of fuel.

Electric rates include provisions to recognize the recovery of fuel costs, purchased power costs, PPAs certificated by the Alabama PSC, and costs associated with the natural disaster reserve. Under these provisions, fuel and other cost recovery revenues generally equal fuel and other cost recovery expenses and do not affect net income. See Note 2 to the financial statements under "Alabama Power" in Item 8 of the Form 10-K for additional information.

Wholesale Revenues – Non-Affiliates

(change in millions) (% change) (change in millions) (% change)
$(8) (12.9) $(12) (9.8)

Wholesale revenues from sales to non-affiliates will vary depending on fuel prices, the market prices of wholesale

energy compared to the cost of Alabama Power's and the Southern Company system's generation, demand for

energy within the Southern Company system's service territory, and the availability of the Southern Company

system's generation. Increases and decreases in energy revenues that are driven by fuel prices are accompanied by

an increase or decrease in fuel costs and do not affect net income. Short-term opportunity energy sales are also

included in wholesale energy sales to non-affiliates. These opportunity sales are made at market-based rates that

generally provide a margin above Alabama Power's variable cost to produce the energy.

In the second quarter 2020, wholesale revenues from sales to non-affiliates were $54 million compared to $62 million for the corresponding period in 2019. For year-to-date 2020, wholesale revenues from sales to non-affiliates were $111 million compared to $123 million for the corresponding period in 2019. These decreases were primarily due to decreases of 16.0% and 9.8% in the price of energy in the second quarter and year-to-date 2020, respectively, primarily due to lower natural gas prices in 2020 compared to the corresponding periods in 2019. Also contributing to the increase for the second quarter 2020 was a 3.2% decrease in KWH sales as a result of lower market demand.

Wholesale revenues from sales to affiliated companies will vary depending on demand and the availability and cost of generating resources at each company. These affiliate sales are made in accordance with the IIC, as approved by the FERC. These transactions do not have a significant impact on earnings since this energy is generally sold at

marginal cost and energy purchases are generally offset by energy revenues through Alabama Power's energy cost recovery clause.

For year-to-date 2020, wholesale revenues from sales to affiliates were $26 million compared to $63 million for the corresponding period in 2019. The decrease was primarily due to a 46.6% decrease in KWH sales as a result of decreased coal generation largely due to lower natural gas prices and a 25.9% decrease in the price of energy due to lower natural gas prices in 2020 compared to the corresponding period in 2019.

$12 17.4 $9 6.3

In the second quarter 2020, other revenues were $81 million compared to $69 million for the corresponding period in 2019. This increase was primarily due to an increase in transmission revenues associated with the timing of customer refunds and an increase in unregulated sales of products and services associated with energy efficiency and equipment upgrade projects.

Purchased power – affiliates (39 ) (56.5 ) (41 ) (45.6 )
Total fuel and purchased power expenses $ (90 ) $ (174 )

In the second quarter 2020, fuel and purchased power expenses were $278 million compared to $368 million for the corresponding period in 2019. The decrease was primarily due to a $77 million decrease in the volume of KWHs generated (excluding hydro) and purchased and a $13 million net decrease in the average cost of generation and purchased power.

For year-to-date 2020, fuel and purchased power expenses were $553 million compared to $727 million for the corresponding period in 2019. The decrease was primarily due to a $140 million decrease in the volume of KWHs generated (excluding hydro) and purchased and a $34 million net decrease in the average cost of generation and purchased power.

Fuel and purchased power energy transactions do not have a significant impact on earnings since energy expenses are generally offset by energy revenues through Alabama Power's energy cost recovery clause. See Note 2 to the financial statements under "Alabama Power – Rate ECR" in Item 8 of the Form 10-K for additional information.

Fuel

In the second quarter 2020, fuel expense was $199 million compared to $252 million for the corresponding period in 2019. The decrease was primarily due to a 25.6% decrease in the volume of KWHs generated by coal, a 21.4% decrease in the average cost of natural gas per KWH generated, which excludes fuel associated with tolling agreements, and increases of 23.5% and 18.9% in the volume of KWHs generated by hydro and nuclear, respectively.

For year-to-date 2020, fuel expense was $415 million compared to $553 million for the corresponding period in 2019. The decrease was primarily due to a 29.6% decrease in the volume of KWHs generated by coal, an 18.2% decrease in the average cost of natural gas per KWH generated, which excludes fuel associated with tolling agreements, and increases of 11.9% and 11.0% in the volume of KWHs generated by nuclear and hydro, respectively.

Purchased Power – Affiliates

In the second quarter 2020, purchased power expense from affiliates was $30 million compared to $69 million for the corresponding period in 2019. For year-to-date 2020, purchased power expense from affiliates was $49 million compared to $90 million for the corresponding period in 2019. The second quarter and year-to-date 2020 decreases were primarily due to reductions of 50.8% and 43.7%, respectively, in the amount of energy purchased due to milder weather during 2020 as compared to 2019 and decreases of 10.7% and 4.3%, respectively, in the average cost of purchased power per KWH as a result of lower natural gas prices in 2020 compared to the corresponding periods in 2019.

Energy purchases from affiliates will vary depending on demand and the availability and cost of generating resources at each company within the Southern Company system. These purchases are made in accordance with the IIC or other contractual agreements, all as approved by the FERC.

1, 2020, including higher depreciation and amortization, largely offset by increased retail rates and lower income tax expense. Also contributing to the decreases were lower retail revenues associated with milder weather as compared to the corresponding periods in 2019 and decreased customer usage resulting from the COVID-19 pandemic, partially offset by related cost containment activities. See Note (B) to the Condensed Financial Statements under "Nuclear Construction" herein for additional information on the construction of Plant Vogtle Units 3 and 4 and Note 2 to the financial statements under "Georgia Power" in Item 8 of the Form 10-K for additional information on the 2019 ARP.

Retail Revenues

(change in millions) (% change) (change in millions) (% change)
$(186) (9.6) $(179) (5.0)

In the second quarter 2020, retail revenues were $1.76 billion compared to $1.95 billion for the corresponding period in 2019. For year-to-date 2020, retail revenues were $3.44 billion compared to $3.61 billion for the corresponding period in 2019.

Details of the changes in retail revenues were as follows:

Second Quarter 2020 Year-to-Date 2020
(in millions) (% change) (in millions) (% change)
Retail – prior year $ 1,946 $ 3,614
Estimated change resulting from –
Rates and pricing 116 5.9 % 209 5.8 %
Sales decline (63 ) (3.2 ) (47 ) (1.3 )
Weather (88 ) (4.5 ) (107 ) (3.0 )
Fuel cost recovery (151 ) (7.8 ) (234 ) (6.5 )
Retail – current year $ 1,760 (9.6 )% $ 3,435 (5.0 )%

Revenues associated with changes in rates and pricing increased in the second quarter and year-to-date 2020, when compared to the corresponding periods in 2019. These increases were primarily due to an increase in revenue recognized under the ECCR tariff effective January 1, 2020 as authorized in the 2019 ARP, the impacts of accruals in 2019 for customer refunds related to Tax Reform, and the rate pricing effects of decreased customer usage in 2020. Partially offsetting these increases were lower contributions from commercial and industrial customers with variable demand-driven pricing. See Note 2 to the financial statements under "Georgia Power" in Item 8 of the Form 10-K for additional information.

Revenues attributable to changes in sales decreased in the second quarter and year-to-date 2020 when compared to the corresponding periods in 2019 largely due to social distancing and shelter-in-place guidelines related to the COVID-19 pandemic. Weather-adjusted residential KWH sales increased 4.7% and 4.1% in the second quarter and year-to-date 2020, respectively, when compared to corresponding periods in 2019 due to customer growth and an increase in average customer usage, primarily due to the temporary suspension of customer disconnections for nonpayment and shelter-in-place orders. Weather-adjusted commercial KWH sales decreased 11.3% and 5.8% in the second quarter and year-to-date 2020, respectively, when compared to the corresponding periods in 2019 primarily due to lower customer usage resulting from shelter-in-place orders and restrictions on business operations in response to the COVID-19 pandemic. Weather-adjusted industrial KWH sales decreased 13.4% and 8.4% in the second quarter and year-to-date 2020, respectively, when compared to the corresponding periods in 2019 as a result of disruptions in supply chain and business operations related to the COVID-19 pandemic and the overall decrease in business activity due to the resulting recession.

Fuel revenues and costs are allocated between retail and wholesale jurisdictions. Retail fuel cost recovery revenues decreased in the second quarter and year-to-date 2020 when compared to the corresponding periods in 2019 due to lower fuel and purchased power costs. Electric rates include provisions to periodically adjust billings for fluctuations in fuel costs, including the energy component of purchased power costs. Under these fuel cost recovery provisions, fuel revenues generally equal fuel expenses and do not affect net income. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Regulatory Matters – Georgia Power – Fuel Cost Recovery" in Item 7 of the Form 10-K for additional information.

Wholesale Revenues

Second Quarter 2020 vs. Second Quarter 2019 Year-to-Date 2020 vs. Year-to-Date 2019
(change in millions) (% change) (change in millions) (% change)
$(11) (30.6) $(16) (23.9)

Wholesale revenues from sales to non-affiliates consist of PPAs and short-term opportunity sales. Wholesale revenues from PPAs have both capacity and energy components. Wholesale capacity revenues from PPAs are recognized either on a levelized basis over the appropriate contract period or the amounts billable under the contract terms and provide for recovery of fixed costs and a return on investment. Wholesale revenues from sales to non-affiliates will vary depending on fuel prices, the market prices of wholesale energy compared to the cost of Georgia Power's and the Southern Company system's generation, demand for energy within the Southern Company system's electric service territory, and the availability of the Southern Company system's generation. Increases and decreases in energy revenues that are driven by fuel prices are accompanied by an increase or decrease in fuel costs and do not have a significant impact on net income. Short-term opportunity sales are made at market-based rates that generally provide a margin above Georgia Power's variable cost of energy.

Wholesale revenues from sales to affiliated companies will vary depending on demand and the availability and cost of generating resources at each company. These affiliate sales are made in accordance with the IIC, as approved by the FERC. These transactions do not have a significant impact on earnings since this energy is generally sold at marginal costs.

In the second quarter 2020, wholesale revenues were $25 million compared to $36 million for the corresponding period in 2019. For year-to-date 2020, wholesale revenues were $51 million compared to $67 million for the corresponding period in 2019. These decreases were primarily due to lower market demand largely resulting from the expiration of a non-affiliate PPA and lower energy prices.

Other Revenues

Second Quarter 2020 vs. Second Quarter 2019 Year-to-Date 2020 vs. Year-to-Date 2019
(change in millions) (% change) (change in millions) (% change)
$8 5.9 $(2) (0.7)

In the second quarter 2020, other revenues were $143 million compared to $135 million for the corresponding period in 2019. The increase was primarily due to an increase of $14 million in unregulated sales associated with power delivery construction and maintenance contracts, partially offset by a decrease of $7 million in pole attachment revenues.

For year-to-date 2020, other revenues were $268 million compared to $270 million for the corresponding period in 2019. The decrease was primarily due to a $13 million decrease in pole attachment revenues and an $8 million decrease in retail customer fees largely resulting from the temporary suspension of customer disconnections and late fees related to the COVID-19 pandemic, substantially offset by an increase of $20 million in unregulated sales associated with power delivery construction and maintenance contracts and outdoor lighting.

In the second quarter 2020, total fuel and purchased power expenses were $481 million compared to $648 million for the corresponding period in 2019. For year-to-date 2020, total fuel and purchased power expenses were $971 million compared to $1.24 billion for the corresponding period in 2019. These decreases were due to decreases of $101 million and $193 million related to the average cost of fuel and purchased power and net decreases of $66 million and $77 million related to the volume of KWHs generated and purchased in second quarter and year-to-date 2020, respectively.

Fuel and purchased power energy transactions do not have a significant impact on earnings since these fuel expenses are generally offset by fuel revenues through Georgia Power's fuel cost recovery mechanism. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Regulatory Matters – Georgia Power – Fuel Cost Recovery" in Item 7 of the Form 10-K for additional information.

Fuel

In the second quarter 2020, fuel expense was $226 million compared to $390 million for the corresponding period in 2019. For year-to-date 2020, fuel expense was $458 million compared to $689 million for the corresponding period in 2019. The decreases for the second quarter and year-to-date 2020 were primarily due to decreases of 21.1% and 18.0%, respectively, in the average cost of fuel primarily related to lower cost of natural gas and decreases of 9.2% and 6.9%, respectively, in the volume of KWHs generated largely due to lower customer demand.

Purchased Power – Non-Affiliates

In the second quarter 2020, purchased power expense from non-affiliates was $133 million compared to $124 million for the corresponding period in 2019. For year-to-date 2020, purchased power expense from non-affiliates was $262 million compared to $242 million for the corresponding period in 2019. The increases for the second quarter and year-to-date 2020 were primarily due to increases of 11.0% and 24.6%, respectively, in the volume of KWHs purchased primarily due to the availability of lower cost market resources, largely offset by decreases of 6.0% and 12.4%, respectively, in the average cost per KWH purchased primarily due to lower energy prices.

Energy purchases from non-affiliates will vary depending on the market prices of wholesale energy as compared to the cost of the Southern Company system's generation, demand for energy within the Southern Company system's electric service territory, and the availability of the Southern Company system's generation.

Purchased Power – Affiliates

In the second quarter 2020, purchased power expense from affiliates was $122 million compared to $134 million for the corresponding period in 2019. For year-to-date 2020, purchased power expense from affiliates was $251 million compared to $310 million for the corresponding period in 2019. The decreases for the second quarter and year-to-date 2020 were primarily due to decreases of 32.8% and 29.0%, respectively, in the average cost per KWH purchased primarily resulting from lower energy prices and the expiration of a PPA. Partially offsetting the decrease in the second quarter 2020 was a 10.4% increase in the volume of KWHs purchased as Georgia Power units generally dispatched at a higher cost than other Southern Company system resources.

Energy purchases from affiliates will vary depending on demand and the availability and cost of generating resources at each company within the Southern Company system. These purchases are made in accordance with the IIC or other contractual agreements, all as approved by the FERC.

(change in millions) (% change) (change in millions) (% change)
$— $15 1.6

In the second quarter 2020 and 2019, other operations and maintenance expenses were $463 million. Increases of $46 million in storm damage recovery as authorized in the 2019 ARP and $10 million in expenses from unregulated sales associated with power delivery construction and maintenance contracts were substantially offset by decreases of $22 million associated with generation maintenance and scheduled outages, $8 million associated with generation environmental projects, $7 million in customer accounts and sales costs, and $7 million in transmission-related expenses. These decreases reflect the impacts of cost containment activities implemented to help offset the effects of the recessionary economy resulting from the COVID-19 pandemic. Also contributing to the offset was a decrease of $8 million related to an adjustment in 2019 for FERC fees following the conclusion of a multi-year audit of headwater benefits associated with hydro facilities.

For year-to-date 2020, other operations and maintenance expenses were $928 million compared to $913 million for the corresponding period in 2019. The increase was primarily due to increases of $92 million in storm damage recovery as authorized in the 2019 ARP and $9 million in expenses from unregulated sales associated with power delivery construction and maintenance contracts, partially offset by decreases of $26 million associated with generation maintenance and scheduled outages, $18 million in distribution- and transmission-related expenses, and $9 million associated with generation environmental projects. These decreases reflect the impacts of cost containment activities implemented to help offset the effects of the recessionary economy resulting from the COVID-19 pandemic. Other expense reductions include a decrease of $15 million related to an adjustment in 2019 for FERC fees following the conclusion of a multi-year audit of headwater benefits associated with hydro facilities and an $11 million increase in nuclear property insurance refunds.

Details of the changes in retail revenues were as follows:

Second Quarter 2020 Year-to-Date 2020
(in millions) (% change) (in millions) (% change)
Retail – prior year $ 215 $ 418

Fuel and other cost recovery (3 ) (1.3 ) (9 ) (2.1 )
Retail – current year $ 199 (7.4 )% $ 398 (4.8 )%

Revenues associated with changes in rates and pricing decreased in the second quarter and year-to-date 2020 when compared to the corresponding periods in 2019 primarily due to decreases in PEP and ECO Plan rates that became effective for the first billing cycle of April 2020, partially offset by revenue associated with a tolling arrangement. See FUTURE EARNINGS POTENTIAL – "Regulatory Matters – Mississippi Power – 2019 Base Rate Case" herein for additional information.

Revenues attributable to changes in sales decreased in the second quarter and year-to-date 2020 when compared to the corresponding periods in 2019 largely due to lower overall customer usage resulting from shelter-in-place orders and restrictions on business operations in response to the COVID-19 pandemic.

Weather-adjusted residential KWH sales increased 5.4% and 2.3% in the second quarter and year-to-date 2020, respectively, primarily due to customer growth and an increase in average customer usage as a result of shelter-in-place orders and the temporary suspension of customer disconnections. Weather-adjusted commercial KWH sales decreased 11.6% and 7.9% in the second quarter and year-to-date 2020, respectively, primarily due to lower customer usage resulting from shelter-in-place orders and restrictions on business operations, including the temporary closure of casinos, in response to the COVID-19 pandemic. Industrial KWH sales decreased 7.0% and 1.3% in the second quarter and year-to-date 2020, respectively, as a result of disruptions in supply chain and business operations driven by the COVID-19 pandemic and the overall decrease in business activity due to the resulting recession.

Fuel and other cost recovery revenues decreased in the second quarter and year-to-date 2020 when compared to the corresponding periods in 2019 primarily as a result of lower recoverable fuel costs. Recoverable fuel costs include fuel and purchased power expenses reduced by the fuel portion of wholesale revenues from energy sold to customers outside Mississippi Power's service territory. Electric rates include provisions to adjust billings for fluctuations in fuel costs, including the energy component of purchased power costs. Under these provisions, fuel revenues generally equal fuel expenses, including the energy component of purchased power costs, and do not affect net income.

Wholesale Revenues – Non-Affiliates

Second Quarter 2020 vs. Second Quarter 2019 Year-to-Date 2020 vs. Year-to-Date 2019
(change in millions) (% change) (change in millions) (% change)

Wholesale revenues from sales to non-affiliates will vary depending on fuel prices, the market prices of wholesale energy compared to the cost of Mississippi Power's and the Southern Company system's generation, demand for energy within the Southern Company system's electric service territory, and the availability of the Southern Company system's generation. Increases and decreases in energy revenues that are driven by fuel prices are accompanied by an increase or decrease in fuel costs and do not have a significant impact on net income. In addition, Mississippi Power provides service under long-term contracts with rural electric cooperative associations

and municipalities located in southeastern Mississippi under cost-based electric tariffs which are subject to regulation by the FERC. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Regulatory Matters – Mississippi Power" in Item 7 of the Form 10-K for additional information.

In the second quarter 2020, wholesale revenues from sales to non-affiliates were $52 million compared to $57 million for the corresponding period in 2019. For year-to-date 2020, wholesale revenues from sales to non-affiliates were $103 million compared to $114 million for the corresponding period in 2019. These decreases were primarily due to decreases in revenue from MRA customers as a result of lower fuel costs and milder weather, as well as fewer opportunity sales.

(change in millions) (% change) (change in millions) (% change)
$(12) (32.4) $(11) (19.0)

Wholesale revenues from sales to affiliated companies will vary depending on demand and the availability and cost of generating resources at each company. These affiliate sales are made in accordance with the IIC, as approved by the FERC. These transactions do not have a significant impact on earnings since this energy is generally sold at marginal cost.

In the second quarter 2020, wholesale revenues from sales to affiliates were $25 million compared to $37 million for the corresponding period in 2019. For year-to-date 2020, wholesale revenues from sales to affiliates were $47 million compared to $58 million for the corresponding period in 2019. These decreases were primarily due to decreases of $18 million and $26 million in the second quarter and year-to-date 2020, respectively, associated with lower natural gas prices, partially offset by increases of $6 million and $14 million in the second quarter and year-to-date 2020, respectively, associated with higher KWH sales due to the dispatch of Mississippi Power's lower cost generation resources to serve the Southern Company system's territorial load.

Fuel and Purchased Power Expenses

Fuel $ (22 ) (21.0) $ (36 ) (18.2)
Purchased power 1 16.7 3 33.3
Total fuel and purchased power expenses $ (21 ) $ (33 )

In the second quarter 2020, total fuel and purchased power expenses were $90 million compared to $111 million for the corresponding period in 2019. The decrease was primarily due to a $20 million decrease related to the cost of fuel primarily due to the lower average cost of natural gas.

For year-to-date 2020, total fuel and purchased power expenses were $174 million compared to $207 million for the corresponding period in 2019. The decrease was primarily due to a $42 million decrease related to the cost of fuel and purchased power primarily due to the lower average cost of natural gas, partially offset by a $9 million increase associated with the volume of KWHs generated and purchased.

Fuel and purchased power energy transactions do not have a significant impact on earnings since energy expenses are generally offset by energy revenues through Mississippi Power's fuel cost recovery clause.

In the second quarter 2020, fuel expense was $83 million compared to $105 million for the corresponding period in 2019. This decrease was due to a 19.0% decrease in the average cost of fuel per KWH generated and a 2.6% decrease in the volume of KWHs generated.

For year-to-date 2020, fuel expense was $162 million compared to $198 million for the corresponding period in 2019. This decrease was due to a 19.5% decrease in the average cost of fuel per KWH generated, partially offset by a 1.8% increase in the volume of KWHs generated.

Purchased Power

In the second quarter 2020, purchased power expense was $7 million compared to $6 million for the corresponding period in 2019. For year-to-date 2020, purchased power expense was $12 million compared to $9 million for the corresponding period in 2019. These increases were primarily the result of 36.3% and 63.2% increases in the volume of KWHs purchased in the second quarter and year-to-date 2020, respectively, largely offset by 13.5% and 20.9% decreases in the average cost per KWH purchased in the second quarter and year-to-date 2020, respectively.

Energy purchases will vary depending on the market prices of wholesale energy as compared to the cost of the Southern Company system's generation, demand for energy within the Southern Company system's electric service territory, and the availability of the Southern Company system's generation. These purchases are made in accordance with the IIC or other contractual agreements, as approved by the FERC.

$(5) (6.9) $9 6.8

In the second quarter 2020, other operations and maintenance expenses were $67 million compared to $72 million for the corresponding period in 2019. The decrease was primarily due to a decrease of $5 million in scheduled generation outage costs.

For year-to-date 2020, other operations and maintenance expenses were $142 million compared to $133 million for the corresponding period in 2019. The increase was primarily due to increases of $5 million in scheduled generation outage costs, $3 million in vegetation management expenses, and $2 million in certain employee compensation expenses previously deferred in 2019.

In the second quarter 2020, depreciation and amortization was $46 million compared to $48 million for the corresponding period in 2019. For year-to-date 2020, depreciation and amortization was $88 million compared to $95 million for the corresponding period in 2019. These decreases were related to decreases in amortization of $8 million and $14 million in the second quarter and year-to-date 2020, respectively, primarily as a result of the ECO Plan regulatory assets being fully amortized in 2019, partially offset by amortization of a regulatory asset associated with an ARO. These decreases were partially offset by increases in depreciation of $6 million and $7 million in the second quarter and year-to-date 2020, respectively, primarily related to additional plant in service and an increase in depreciation rates in accordance with the Mississippi Power Rate Case Settlement Agreement.

(change in millions) (% change) (change in millions) (% change)
$(111) (63.8) $(92) (40.0)

Net income attributable to Southern Power for the second quarter 2020 was $63 million compared to $174 million for the corresponding period in 2019. The decrease was primarily due to the gain on the sale of Plant Nacogdoches in the second quarter 2019 of $88 million after tax. In addition, the decrease was due to reduced net income related to the dispositions of Plant Nacogdoches in 2019 and Plant Mankato in the first quarter 2020. The decrease also reflects net gains in the second quarter 2019 totaling $22 million from the Roserock solar facility litigation settlement and sales of wind equipment.

Net income attributable to Southern Power for year-to-date 2020 was $138 million compared to $230 million for the corresponding period in 2019. The decrease was primarily due to the gain on the sale of Plant Nacogdoches in the second quarter 2019 of $88 million after tax, partially offset by the gain on sale of Plant Mankato in the first quarter 2020 of $23 million after tax. In addition, the decrease was due to reduced net income related to the dispositions of Plant Nacogdoches and Plant Mankato. The decrease also reflects net gains in the second quarter 2019 totaling $22 million from the Roserock solar facility litigation settlement and sales of wind equipment.

See Note (K) to the Condensed Financial Statements under "Southern Power" herein and Note 15 to the financial statements under "Southern Power" in Item 8 of the Form 10-K for additional information.

Operating Revenues

Second Quarter 2020 vs. Second Quarter 2019 Year-to-Date 2020 vs. Year-to-Date 2019
(change in millions) (% change) (change in millions) (% change)
$(71) (13.9) $(139) (14.6)

Total operating revenues include PPA capacity revenues, which are derived primarily from long-term contracts involving natural gas facilities and a biomass generating facility (through the second quarter 2019 sale of Plant Nacogdoches), and PPA energy revenues from Southern Power's generation facilities. To the extent Southern Power has capacity not contracted under a PPA, it may sell power into an accessible wholesale market, or, to the extent those generation assets are part of the FERC-approved IIC, it may sell power into the Southern Company power pool.

Natural Gas and Biomass Capacity and Energy Revenue

Capacity revenues generally represent the greatest contribution to operating income and are designed to provide recovery of fixed costs plus a return on investment.

Energy is generally sold at variable cost or is indexed to published natural gas indices. Energy revenues will vary depending on the energy demand of Southern Power's customers and their generation capacity, as well as the market prices of wholesale energy compared to the cost of Southern Power's energy. Energy revenues also include fees for support services, fuel storage, and unit start charges. Increases and decreases in energy revenues under PPAs that are driven by fuel or purchased power prices are accompanied by an increase or decrease in fuel and purchased power costs and do not have a significant impact on net income.

Solar and Wind Energy Revenue

Southern Power's energy sales from solar and wind generating facilities are predominantly through long-term PPAs that do not have capacity revenue. Customers either purchase the energy output of a dedicated renewable facility through an energy charge or pay a fixed price related to the energy generated from the respective facility and sold to

the grid. As a result, Southern Power's ability to recover fixed and variable operations and maintenance expenses is dependent upon the level of energy generated from these facilities, which can be impacted by weather conditions, equipment performance, transmission constraints, and other factors.

See FUTURE EARNINGS POTENTIAL – "Southern Power's Power Sales Agreements" herein for additional information regarding Southern Power's PPAs.

Operating Revenues Details

Details of Southern Power's operating revenues were as follows:

Second Quarter 2020 Second Quarter 2019 Year-to-Date 2020 Year-to-Date 2019
(in millions)
PPA capacity revenues $ 92 $ 125 $ 181 $ 252
PPA energy revenues 270 291 475 518
Total PPA revenues 362 416 656 770
Non-PPA revenues 73 91 151 177
Other revenues 4 3 7 6
Total operating revenues $ 439 $ 510 $ 814 $ 953

In the second quarter 2020, total operating revenues were $439 million, reflecting a $71 million, or 14%, decrease from the corresponding period in 2019. The decrease in operating revenues was primarily due to the following:

PPA capacity revenues decreased $33 million, or 26%, primarily due to decreases of $22 million related to the dispositions of Plant Nacogdoches in the second quarter 2019 and Plant Mankato in the first quarter 2020 and $10 million from the contractual expiration of an affiliate natural gas PPA.
PPA energy revenues decreased $21 million, or 7%, due to a $46 million decrease in sales from natural gas facilities resulting from a $25 million decrease in the volume of KWHs sold due to reduced demand and a $21 million decrease in the average cost of fuel and purchased power. This decrease was partially offset by a $13 million increase in sales primarily driven by the volume of KWHs generated by solar and wind facilities and a $12 million increase in sales from a fuel cell project acquired in late 2019.
--- ---
Non-PPA revenues decreased $18 million, or 20%, due to a $40 million decrease in the market price of energy, partially offset by a $23 million increase in the volume of KWHs sold through short-term sales.
--- ---

For year-to-date 2020, total operating revenues were $814 million, reflecting a $139 million, or 15%, decrease from the corresponding period in 2019. The decrease in operating revenues was primarily due to the following:

PPA capacity revenues decreased $71 million, or 28%, primarily due to decreases of $45 million related to the dispositions of Plant Nacogdoches in the second quarter 2019 and Plant Mankato in the first quarter 2020 and $24 million from the contractual expiration of an affiliate natural gas PPA.
PPA energy revenues decreased $43 million, or 8%, due to an $86 million decrease in sales from natural gas facilities resulting from a $49 million decrease in the price of fuel and purchased power and a $37 million decrease in the volume of KWHs sold due to reduced demand. This decrease was partially offset by increases of $23 million in sales primarily driven by the volume of KWHs generated by solar and wind facilities and $20 million in sales from a fuel cell project acquired in late 2019.

Fuel and Purchased Power Expenses

Details of Southern Power's generation and purchased power were as follows:

Second Quarter 2020 Second Quarter 2019 Year-to-Date 2020 Year-to-Date 2019
(in billions of KWHs)
Generation 11.3 11.7 22.0 21.9
Purchased power 0.9 1.0 1.5 1.8
Total generation and purchased power 12.2 12.7 23.5 23.7
Total generation and purchased power, excluding solar, wind, and tolling agreements 7.4 7.1 14.5 13.7

Southern Power's PPAs for natural gas generation generally provide that the purchasers are responsible for either procuring the fuel (tolling agreements) or reimbursing Southern Power for substantially all of the cost of fuel relating to the energy delivered under such PPAs. Consequently, changes in such fuel costs are generally accompanied by a corresponding change in related fuel revenues and do not have a significant impact on net income. Southern Power is responsible for the cost of fuel for generating units that are not covered under PPAs. Power from these generating units is sold into the wholesale market or into the Southern Company power pool for capacity owned directly by Southern Power.

Purchased power expenses will vary depending on demand, availability, and the cost of generating resources throughout the Southern Company system and other contract resources. Load requirements are submitted to the Southern Company power pool on an hourly basis and are fulfilled with the lowest cost alternative, whether that is generation owned by Southern Power, an affiliate company, or external parties. Such purchased power costs are generally recovered through PPA revenues.

Details of Southern Power's fuel and purchased power expenses were as follows:

Second Quarter 2020 vs. Second Quarter 2019 Year-to-Date 2020 vs. Year-to-Date 2019
(change in millions) (% change) (change in millions) (% change)

Purchased power (14 ) (43.8) (23 ) (41.8)
Total fuel and purchased power expenses $ (51 ) $ (98 )

In the second quarter 2020, total fuel and purchased power expenses decreased $51 million, or 30%, compared to the corresponding period in 2019. Fuel expense decreased $37 million due to a $46 million decrease in the average cost of fuel per KWH generated, partially offset by a $9 million increase associated with the volume of KWHs generated. Purchased power expense decreased $14 million due to a $9 million decrease associated with the average cost of purchased power and a $5 million decrease associated with the volume of KWHs purchased.

For year-to-date 2020, total fuel and purchased power expenses decreased $98 million, or 29%, compared to the corresponding period in 2019. Fuel expense decreased $75 million due to a $98 million decrease in the average cost of fuel per KWH generated, partially offset by a $23 million increase associated with the volume of KWHs generated. Purchased power expense decreased $23 million due to a $16 million decrease associated with the average cost of purchased power and a $7 million decrease associated with the volume of KWHs purchased.

Southern Company Gas

Operating Metrics

Southern Company Gas continues to focus on several operating metrics, including Heating Degree Days, customer count, and volumes of natural gas sold.

Southern Company Gas measures weather and the effect on its business using Heating Degree Days. Generally, increased Heating Degree Days result in higher demand for natural gas on Southern Company Gas' distribution system. Southern Company Gas has various regulatory mechanisms, such as weather and revenue normalization and straight-fixed-variable rate design, which limit its exposure to weather changes within typical ranges in each of its utility's respective service territory, including Nicor Gas following the approval of a revenue decoupling mechanism for residential customers in its base rate case that concluded in 2019. Southern Company Gas also utilizes weather hedges to limit the negative income impacts in the event of warmer-than-normal weather.

The number of customers served by gas distribution operations and gas marketing services can be impacted by natural gas prices, economic conditions, and competition from alternative fuels. Gas distribution operations and gas marketing services' customers are primarily located in Georgia, Illinois, and Ohio.

Southern Company Gas' natural gas volume metrics for gas distribution operations and gas marketing services illustrate the effects of weather and customer demand for natural gas. Wholesale gas services' physical sales volumes represent the daily average natural gas volumes sold to its customers.

Seasonality of Results

During the Heating Season, natural gas usage and operating revenues are generally higher as more customers are connected to the gas distribution systems and natural gas usage is higher in periods of colder weather. Occasionally in the summer, wholesale gas services' operating revenues are impacted due to peak usage by power generators in response to summer energy demands. Southern Company Gas' base operating expenses, excluding cost of natural gas, bad debt expense, and certain incentive compensation costs, are incurred relatively evenly throughout the year. Seasonality also affects the comparison of certain balance sheet items across quarters, including receivables, unbilled revenues, natural gas for sale, and notes payable. However, these items are comparable when reviewing Southern Company Gas' annual results. Thus, Southern Company Gas' operating results for the interim periods presented are not necessarily indicative of annual results and can vary significantly from quarter to quarter.

Net Income

Second Quarter 2020 vs. Second Quarter 2019 Year-to-Date 2020 vs. Year-to-Date 2019
(change in millions) (% change) (change in millions) (% change)
$(35) (33.0) $(30) (8.0)

In the second quarter 2020, net income was $71 million compared to $106 million for the corresponding period in 2019. This decrease was primarily due to a $46 million decrease at wholesale gas services primarily due to reduced natural gas price volatility compared to the prior year and a $7 million gain from the sale of Triton in 2019, partially offset by a $16 million increase at gas distribution operations primarily due to base rate increases for Nicor Gas and Atlanta Gas Light and continued investment in infrastructure replacement programs, partially offset by reduced flowback of excess deferred income taxes at Atlanta Gas Light in 2020.

For year-to-date 2020, net income was $346 million compared to $376 million for the corresponding period in 2019. This decrease in net income was primarily due to a $70 million decrease at wholesale gas services primarily due to reduced natural gas price volatility compared to the prior year and a $7 million gain from the sale of Triton in 2019, partially offset by a $47 million increase at gas distribution operations primarily due to base rate increases for Nicor Gas and Atlanta Gas Light and continued investment in infrastructure replacement programs, partially offset by reduced flowback of excess deferred income taxes at Atlanta Gas Light in 2020.

(change in millions) (% change) (change in millions) (% change)
$(53) (7.7) $(278) (12.9)

In the second quarter 2020, natural gas revenues, including alternative revenue programs, were $636 million compared to $689 million for the corresponding period in 2019. For year-to-date 2020, natural gas revenues, including alternative revenue programs, were $1.9 billion compared to $2.2 billion for the corresponding period in 2019.

Details of the changes in natural gas revenues, including alternative revenue programs, were as follows:

Second Quarter 2020 Year-to-Date 2020
(in millions) (% change) (in millions) (% change)
Natural gas revenues – prior year $ 689 $ 2,163
Estimated change resulting from –
Infrastructure replacement programs and base rate changes 43 6.2 % 119 5.5 %
Gas costs and other cost recovery (38 ) (5.5 ) (287 ) (13.3 )
Weather 3 0.4 (8 ) (0.4 )
Wholesale gas services (67 ) (9.7 ) (102 ) (4.7 )
Other 6 0.9
Natural gas revenues – current year $ 636 (7.7 )% $ 1,885 (12.9 )%

Revenues from infrastructure replacement programs and base rate changes increased in the second quarter and year-to-date 2020 compared to the corresponding periods in 2019 primarily due to base rate increases at Nicor Gas and Atlanta Gas Light and continued investments recovered through infrastructure replacement programs. See Note 2 to the financial statements under "Southern Company Gas – Rate Proceedings" in Item 8 of the Form 10-K for additional information.

Revenues associated with gas costs and other cost recovery decreased in the second quarter and year-to-date 2020 compared to the corresponding periods in 2019 primarily due to lower natural gas prices and decreased volumes of natural gas sold. Natural gas distribution rates include provisions to adjust billings for fluctuations in natural gas costs. Therefore, gas costs recovered through natural gas revenues generally equal the amount expensed in cost of natural gas and do not affect net income from gas distribution operations. See "Cost of Natural Gas" herein for additional information. Revenue impacts from weather and customer growth are described further below.

Revenues from wholesale gas services decreased in the second quarter and year-to-date 2020 compared to the corresponding periods in 2019 primarily due to decreased commercial activity as a result of warmer weather and a decrease in derivative gains. See "Segment Information – Wholesale Gas Services" herein for additional information.

Southern Company Gas hedged the majority of its exposure to warmer-than-normal weather in Illinois for gas distribution operations and in Illinois and Georgia for gas marketing services. During Heating Season, natural gas usage and operating revenues are generally higher. Weather typically does not have a significant net income impact other than during the Heating Season. The following table presents Heating Degree Days information for Illinois and Georgia, the primary locations where Southern Company Gas' operations are impacted by weather.

Excluding Atlanta Gas Light, which does not sell natural gas to end-use customers, natural gas distribution rates include provisions to adjust billings for fluctuations in natural gas costs. Therefore, gas costs recovered through natural gas revenues generally equal the amount expensed in cost of natural gas and do not affect net income from gas distribution operations. Cost of natural gas at gas distribution operations represented 86% of total cost of natural gas for both the second quarter and year-to-date 2020. See MANAGEMENT'S DISCUSSION AND ANALYSIS – RESULTS OF OPERATIONS – "Southern Company Gas – Cost of Natural Gas" in Item 7 of the Form 10-K and "Natural Gas Revenues, including Alternative Revenue Programs" herein for additional information.

In the second quarter 2020, cost of natural gas was $144 million compared to $191 million for the corresponding period in 2019. This decrease reflects a 34.9% decrease in natural gas prices in the second quarter 2020 compared to the corresponding period in 2019.

For year-to-date 2020, cost of natural gas was $583 million compared to $877 million for the corresponding period in 2019. This decrease reflects a 36.6% decrease in natural gas prices compared to 2019 and decreased volumes primarily as a result of warmer weather for year-to-date 2020 compared to the corresponding period in 2019.

For year-to-date 2020, income taxes were $95 million compared to $83 million for the corresponding period in 2019. These increases were primarily due to a decrease in the flowback of excess deferred income taxes at Atlanta Gas Light as authorized by the Georgia PSC and the reversal of a federal income tax valuation allowance in connection with the sale of Triton in 2019, partially offset by lower pre-tax earnings. See Note (G) to the Condensed Financial Statements herein for additional information.

Performance and Non-GAAP Measures

Adjusted operating margin is a non-GAAP measure that is calculated as operating revenues less cost of natural gas, cost of other sales, and revenue tax expense. Adjusted operating margin excludes other operations and maintenance expenses, depreciation and amortization, and taxes other than income taxes, which are included in the calculation of operating income as calculated in accordance with GAAP and reflected in the statements of income. The presentation of adjusted operating margin is believed to provide useful information regarding the contribution resulting from base rate changes, infrastructure replacement programs and capital projects, and customer growth at gas distribution operations since the cost of natural gas and revenue tax expense can vary significantly and are generally billed directly to customers. Southern Company Gas further believes that utilizing adjusted operating margin at gas pipeline investments, wholesale gas services, and gas marketing services allows it to focus on a direct measure of performance before overhead costs. The applicable reconciliation of operating income to adjusted operating margin is provided herein.

Adjusted operating margin should not be considered an alternative to, or a more meaningful indicator of, Southern Company Gas' operating performance than operating income as determined in accordance with GAAP. In addition, Southern Company Gas' adjusted operating margin may not be comparable to similarly titled measures of other companies.

Gas Distribution Operations

Gas distribution operations is the largest component of Southern Company Gas' business and is subject to regulation and oversight by agencies in each of the states it serves. These agencies approve natural gas rates designed to provide Southern Company Gas with the opportunity to generate revenues to recover the cost of natural gas delivered to its customers and its fixed and variable costs, including depreciation, interest expense, operations and maintenance, taxes, and overhead costs, and to earn a reasonable return on its investments.

With the exception of Atlanta Gas Light, Southern Company Gas' second largest utility that operates in a deregulated natural gas market and has a straight-fixed-variable rate design that minimizes the variability of its revenues based on consumption, the earnings of the natural gas distribution utilities can be affected by customer consumption patterns that are a function of weather conditions, price levels for natural gas, and general economic conditions that may impact customers' ability to pay for natural gas consumed. Southern Company Gas has various regulatory and other mechanisms, such as weather and revenue normalization mechanisms and weather derivative

instruments, that limit its exposure to changes in customer consumption, including weather changes within typical ranges in its natural gas distribution utilities' service territories.

In the second quarter 2020, net income increased $16 million, or 27.6%, compared to the corresponding period in 2019. The $47 million increase in adjusted operating margin primarily reflects base rate increases for Nicor Gas and Atlanta Gas Light and continued investments recovered through infrastructure replacement programs. The $27 million increase in operating expenses includes increased medical and retirement benefit expenses, higher expenses passed through directly to customers, primarily related to bad debt and pipeline compliance and maintenance activities, and higher depreciation primarily due to additional assets placed in service. The $6 million increase in other income is primarily due to an increase in non-service cost-related retirement benefits income. Income tax expense increased $11 million primarily due to higher pre-tax earnings and a decrease in the flowback of excess deferred income taxes at Atlanta Gas Light as authorized by the Georgia PSC.

For year-to-date 2020, net income increased $47 million or 24.6%, compared to the corresponding period in 2019. The $118 million increase in adjusted operating margin primarily reflects base rate increases for Nicor Gas and Atlanta Gas Light and continued investments recovered through infrastructure replacement programs, partially offset by warmer weather, net of weather normalization mechanisms. The $53 million increase in operating expenses includes increased medical and retirement benefit expenses, higher expenses passed through directly to customers, primarily related to bad debt and pipeline compliance and maintenance activities, and additional depreciation primarily due to additional assets placed in service. The $12 million increase in other income is primarily due to an increase in non-service cost-related retirement benefits income. The $31 million increase in income tax expense is primarily due to higher pre-tax earnings and a decrease in the flowback of excess deferred income taxes at Atlanta Gas Light as authorized by the Georgia PSC.

See Note 2 to the financial statements in Item 8 of the Form 10-K and Note (H) to the Condensed Financial Statements herein for additional information.

Gas Pipeline Investments

Gas pipeline investments consists primarily of joint ventures in natural gas pipeline investments including SNG, PennEast Pipeline, Dalton Pipeline, and Atlantic Coast Pipeline (until its sale on March 24, 2020). See Notes (E) and (K) to the Condensed Financial Statements under "Southern Company Gas" herein and Note 7 to the financial statements in Item 8 of the Form 10-K for additional information.

In the second quarter and year-to-date 2020, net income decreased $4 million, or 16.0%, and $6 million, or 10.5%, respectively, compared to the corresponding periods in 2019. These decreases primarily relate to lower earnings at SNG.

Wholesale Gas Services

Wholesale gas services is involved in asset management and optimization, storage, transportation, producer and peaking services, natural gas supply, natural gas services, and wholesale gas marketing. Southern Company Gas has positioned the business to generate positive economic earnings on an annual basis even under low volatility market conditions that can result from a number of factors. When market price volatility increases, wholesale gas services is well positioned to capture significant value and generate stronger results. Operating expenses primarily reflect employee compensation and benefits.

In the second quarter 2020, net income decreased $46 million, or 200.0%, compared to the corresponding period in 2019. This decrease primarily relates to a $60 million decrease in adjusted operating margin, partially offset by a $15 million decrease in income tax expense due to lower pre-tax earnings.

For year-to-date 2020, net income decreased $70 million, or 100.0%, compared to the corresponding period in 2019. This decrease primarily relates to a $94 million decrease in adjusted operating margin and a $1 million decrease in operating expenses, partially offset by a $22 million decrease in income tax expense due to lower pre-tax earnings.

AND RESULTS OF OPERATIONS (Continued)

Details of the changes in adjusted operating margin are provided in the table below.

Second Quarter 2020 Second Quarter 2019 Year-to-Date 2020 Year-to-Date 2019

Purchase accounting adjustments to fair value inventory and contracts (2 ) (1 ) 14
Adjusted operating margin $ (19 ) $ 41 $ 31 $ 125

Change in Commercial Activity

The commercial activity at wholesale gas services includes recognition of storage and transportation values that were generated in prior periods, which reflect the impact of prior period hedge gains and losses as associated physical transactions occur. The decrease in commercial activity in the second quarter and year-to-date 2020 compared to the corresponding periods in 2019 was primarily due to warmer-than-normal weather conditions.

Change in Storage and Transportation Derivatives

Volatility in the natural gas market arises from a number of factors, such as weather fluctuations or changes in supply or demand for natural gas in different regions of the U.S. The volatility of natural gas commodity prices has a significant impact on Southern Company Gas' customer rates, long-term competitive position against other energy sources, and the ability of wholesale gas services to capture value from locational and seasonal spreads. Forward storage or time spreads applicable to the locations of wholesale gas services' specific storage positions in 2020 resulted in storage derivative losses. Transportation and forward commodity derivative gains in 2020 are primarily the result of narrowing transportation spreads due to supply constraints and increases in natural gas supply, which impacted forward prices at natural gas receipt and delivery points, primarily in the Northeast and Midwest regions.

Withdrawal Schedule and Physical Transportation Transactions

The expected natural gas withdrawals from storage and expected offset to prior hedge losses/gains associated with the transportation portfolio of wholesale gas services are presented in the following table, along with the net operating revenues expected at the time of withdrawal from storage and the physical flow of natural gas between contracted transportation receipt and delivery points. Wholesale gas services' expected net operating revenues exclude storage and transportation demand charges, as well as other variable fuel, withdrawal, receipt, and delivery charges, and exclude estimated profit sharing under asset management agreements. Further, the amounts that are realizable in future periods are based on the inventory withdrawal schedule, planned physical flow of natural gas between the transportation receipt and delivery points, and forward natural gas prices at June 30, 2020. A portion of wholesale gas services' storage inventory and transportation capacity is economically hedged with futures contracts, which results in the realization of substantially fixed net operating revenues.

The unrealized storage and transportation derivative gains do not change the underlying economic value of wholesale gas services' storage and transportation positions and will be reversed when the related transactions occur and are recognized. For more information on wholesale gas services' energy marketing and risk management activities, see MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Market Price Risk" in Item 7 of the Form 10-K.

Gas Marketing Services

Gas marketing services provides energy-related products and services to natural gas markets and participants in customer choice programs that were approved in various states to increase competition. These programs allow customers to choose their natural gas supplier while the local distribution utility continues to provide distribution and transportation services. Gas marketing services is weather sensitive and uses a variety of hedging strategies, such as weather derivative instruments and other risk management tools, to partially mitigate potential weather impacts.

In the second quarter 2020, net income increased $8 million compared to the corresponding period in 2019. This increase primarily relates to an $8 million increase in adjusted operating margin, which primarily reflects recovery of prior period hedge losses, and a $3 million decrease in operating expenses, partially offset by a $3 million increase in income tax expense.

For year-to-date 2020, net income increased $4 million compared to the corresponding period in 2019. This increase primarily relates to a $4 million decrease in operating expenses.

All Other

All other includes natural gas storage businesses, fuels operations through the sale of Southern Company Gas' interest in Pivotal LNG on March 24, 2020, the investment in Triton through its sale on May 29, 2019, AGL Services Company, and Southern Company Gas Capital, as well as various corporate operating expenses that are not allocated to the reportable segments and interest income (expense) associated with affiliate financing arrangements. See Note (K) to the Condensed Financial Statements under "Southern Company Gas" herein for additional information on the sale of its interest in Pivotal LNG.

In the second quarter 2020, net income decreased $9 million compared to the corresponding period in 2019. This decrease primarily reflects a $2 million increase in operating expenses and a $12 million increase in income taxes, partially offset by a $7 million increase in other income (expenses). The increase in other income (expenses) was primarily due to a pre-tax loss on the sale of Triton in 2019. The increase in income taxes reflects the reversal of a federal income tax valuation allowance in connection with the sale of Triton in 2019.

AND RESULTS OF OPERATIONS (Continued)

For year-to-date 2020, net income decreased $5 million compared to the corresponding period in 2019. This decrease includes a $2 million increase in interest expense, net of amounts capitalized, and a $6 million increase in income taxes related to the reversal of a federal income tax valuation allowance in connection with the sale of Triton in 2019, partially offset by a $4 million increase in other income (expenses) primarily due to a pre-tax loss on the sale of Triton in 2019.

FUTURE EARNINGS POTENTIAL

Each Registrant's results of operations are not necessarily indicative of its future earnings potential. Recent disposition activities described under "Acquisitions and Dispositions" herein, in Note (K) to the Condensed Financial Statements herein, and in Note 15 to the financial statements in Item 8 of the Form 10-K will impact future earnings for the applicable Registrants. The level of the Registrants' future earnings depends on numerous factors that affect the opportunities, challenges, and risks of the Registrants' primary businesses of selling electricity and/or distributing natural gas, as described further herein.

For the traditional electric operating companies, these factors include the ability to maintain constructive regulatory environments that allow for the timely recovery of prudently-incurred costs during a time of increasing costs, continued customer growth, and the trend of reduced electricity usage per customer, especially in residential and commercial markets. Other major factors include completing construction of Plant Vogtle Units 3 and 4 and related cost recovery proceedings for Georgia Power and the ability to prevail against legal challenges associated with the Kemper County energy facility for Mississippi Power.

Earnings in the electricity business will also depend upon maintaining and growing sales, considering, among other things, the adoption and/or penetration rates of increasingly energy-efficient technologies and increasing volumes of electronic commerce transactions, which could contribute to a net reduction in customer usage.

Global and U.S. economic conditions have been significantly affected by a series of demand and supply shocks that have caused a global and national economic recession. Most prominently, the COVID-19 pandemic has negatively impacted global supply chains and global demand for goods and services and public policy responses of social distancing and closing non-essential businesses have further restricted economic activity. The drivers, speed, and depth of this economic contraction are unprecedented and have reduced energy demand across the Southern Company system's service territory, primarily in the commercial and industrial classes. The negative impacts, which started in late-March 2020, of the COVID-19 pandemic and related recession on the Southern Company system's retail electric sales began to improve in the middle of May 2020; however, retail electric sales through the end of the second quarter 2020 continued to be approximately 3% to 4% lower than levels projected prior to the COVID-19 pandemic. Recovery is expected to continue for the remainder of 2020 and into 2021, but responses to the COVID-19 pandemic by both customers and government could significantly affect the pace of recovery. The ultimate extent of the negative impact on revenues depends on the depth and duration of the economic contraction in the Southern Company system's service territory and cannot be determined at this time. See RESULTS OF OPERATIONS herein for information on COVID-19-related impacts on energy demand in the Southern Company system's service territory during the first six months of 2020.

Alabama Power continues to temporarily suspend disconnections for non-payment by customers and waive late fees as a result of the COVID-19 pandemic. In addition, the traditional electric operating companies have established installment payment plans to allow customers to repay past due accounts over a period of time. See "Regulatory Matters" herein for additional information on the status of disconnections and the deferral of costs resulting from

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

the COVID-19 pandemic at Georgia Power, Mississippi Power, and the natural gas distribution utilities. The ultimate outcome of these matters cannot be determined at this time.

The level of future earnings for Southern Power's competitive wholesale electric business depends on numerous factors including Southern Power's ability to execute its growth strategy through the development or acquisition of renewable facilities and other energy projects while containing costs, as well as regulatory matters, creditworthiness of customers, total electric generating capacity available in Southern Power's market areas, and Southern Power's ability to successfully remarket capacity as current contracts expire. In addition, renewable portfolio standards, transmission constraints, cost of generation from units within the Southern Company power pool, and operational limitations could influence Southern Power's future earnings.

The level of future earnings for Southern Company Gas' primary business of distributing natural gas and its complementary businesses in the gas pipeline investments, wholesale gas services, and gas marketing services sectors depends on numerous factors. These factors include the natural gas distribution utilities' ability to maintain constructive regulatory environments that allow for the timely recovery of prudently-incurred costs, the completion and subsequent operation of ongoing infrastructure and other construction projects, creditworthiness of customers, and Southern Company Gas' ability to optimize its transportation and storage positions and to re-contract storage rates at favorable prices. The volatility of natural gas prices has an impact on Southern Company Gas' customer rates, its long-term competitive position against other energy sources, and the ability of Southern Company Gas' gas marketing services and wholesale gas services businesses to capture value from locational and seasonal spreads. Additionally, changes in commodity prices subject a portion of Southern Company Gas' operations to earnings variability. Over the longer term, volatility is expected to be low to moderate and locational and/or transportation spreads are expected to decrease as new pipelines are built to reduce the existing supply constraints in the shale areas of the Northeast U.S. To the extent these pipelines are further delayed or not built, volatility could increase. See "Construction Programs" herein for additional information on permitting challenges experienced by the PennEast Pipeline. Additional economic factors may contribute to this environment, including a significant drop in oil and natural gas prices, which could lead to consolidation of natural gas producers or reduced levels of natural gas production. In addition, if the COVID-19 pandemic results in a continued economic downturn for a sustained period, demand for natural gas may decrease, resulting in further downward pressure on natural gas prices and lower volatility in the natural gas markets on a longer-term basis.

Earnings for both the electricity and natural gas businesses are subject to a variety of other factors. These factors include weather, competition, developing new and maintaining existing energy contracts and associated load requirements with wholesale customers, energy conservation practiced by customers, the use of alternative energy sources by customers, the prices of electricity and natural gas, and the price elasticity of demand. Demand for electricity and natural gas in the Registrants' service territories is primarily driven by the pace of economic growth or decline that may be affected by changes in regional and global economic conditions, which may impact future earnings.

As part of its ongoing effort to adapt to changing market conditions, Southern Company continues to evaluate and consider a wide array of potential business strategies. These strategies may include business combinations, partnerships, and acquisitions involving other utility or non-utility businesses or properties, disposition of certain assets or businesses, internal restructuring, or some combination thereof. Furthermore, Southern Company may engage in new business ventures that arise from competitive and regulatory changes in the utility industry. Pursuit of any of the above strategies, or any combination thereof, may significantly affect the business operations, risks, and financial condition of Southern Company. In addition, Southern Power and Southern Company Gas regularly consider and evaluate joint development arrangements as well as acquisitions and dispositions of businesses and assets as part of their business strategies.

For additional information relating to these issues, see RISK FACTORS in Item 1A and MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL in Item 7 of the Form 10-K and RISK FACTORS in Item 1A herein.

Acquisitions and Dispositions

See Note 15 to the financial statements in Item 8 of the Form 10-K and Note (K) to the Condensed Financial Statements herein for additional information.

Alabama Power

On April 22, 2020 and June 9, 2020, the FERC and the Alabama PSC, respectively, approved the Autauga Combined Cycle Acquisition, which is expected to close by September 1, 2020. See "Regulatory Matters – Alabama Power" herein for additional information. The ultimate outcome of this matter cannot be determined at this time.

Southern Power

On January 17, 2020, Southern Power completed the sale of its equity interests in Plant Mankato (including the 385-MW expansion unit completed in May 2019) to a subsidiary of Xcel for a purchase price of approximately $663 million, including final working capital adjustments. The sale resulted in a gain of approximately $39 million ($23 million after tax). Pre-tax income for Plant Mankato was immaterial for the six months ended June 30, 2020 and the three and six months ended June 30, 2019.

In March 2020, Southern Power entered into an agreement to acquire a controlling membership interest in an approximately 300-MW wind facility located in South Dakota. The acquisition is subject to FERC approval and certain other customary conditions to closing, including commercial operation of the facility, which is expected to occur in late 2020 or early 2021. The facility's output is contracted under two long-term PPAs. The ultimate outcome of this matter cannot be determined at this time.

On May 1, 2020, Southern Power purchased a controlling interest in the 56-MW Beech Ridge II wind facility located in Greenbrier County, West Virginia from Invenergy Renewables LLC. The facility's output is contracted under a 12-year PPA. See Note (K) to the Condensed Financial Statements herein for additional information.

Southern Power continues to evaluate and refine the deployment of the remaining wind turbine equipment purchased in 2016 and 2017 to development and construction projects. During the six months ended June 30, 2020, certain wind turbine equipment was sold, resulting in an immaterial gain.

Southern Company Gas

On March 24, 2020, Southern Company Gas completed the sale of its interests in Pivotal LNG and Atlantic Coast Pipeline to Dominion Modular LNG Holdings, Inc. and Dominion Atlantic Coast Pipeline, LLC, respectively, with aggregate proceeds of $178 million, including working capital adjustments. The preliminary loss associated with the transactions was immaterial. Southern Company Gas may also receive two future payments of $5 million each, contingent upon certain milestones related to Pivotal LNG being met by Dominion Modular LNG Holdings, Inc. See Note (K) to the Condensed Financial Statements under "Southern Company Gas" herein for additional information.

Environmental Matters

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters" in Item 7 and Note 3 to the financial statements under "Environmental Remediation" in Item 8 of the Form 10-K, as well as Note (C) to the Condensed Financial Statements under "Environmental Remediation" herein, for additional information.

Environmental Laws and Regulations

Coal Combustion Residuals

In June 2020, Alabama Power recorded an increase of approximately $462 million to its AROs related to the CCR Rule and the related state rule primarily due to management's completion of a feasibility study and the related cost estimates during the second quarter 2020 for one of its ash ponds. Alabama Power's increase also reflects costs

AND RESULTS OF OPERATIONS (Continued)

associated with the addition of a water treatment system to the design of another ash pond. The additional estimated costs to close these ash ponds under the planned closure-in-place methodology primarily relate to inputs from contractor bids, design revisions, and changes in the expected volume of ash handling.

The traditional electric operating companies expect to continue updating their cost estimates and ARO liabilities periodically as additional information related to ash pond closure methodologies, schedules, and/or costs becomes available. Additionally, the closure designs and plans in the States of Alabama and Georgia are subject to approval by environmental regulatory agencies. Absent continued recovery of ARO costs through regulated rates, results of operations, cash flows, and financial condition for Southern Company and the traditional electric operating companies could be materially impacted. See Note (B) to the Condensed Financial Statements under "Georgia Power – Integrated Resource Plan" herein for additional information. The ultimate outcome of these matters cannot be determined at this time. See Note 6 to the financial statements in Item 8 of the Form 10-K and Note (A) to the Condensed Financial Statements under "Asset Retirement Obligations" herein for additional information.

Regulatory Matters

See Note 2 to the financial statements in Item 8 of the Form 10-K and Note (B) to the Condensed Financial Statements herein for additional information.

Alabama Power

Alabama Power's revenues from regulated retail operations are collected through various rate mechanisms subject to the oversight of the Alabama PSC. Alabama Power currently recovers its costs from the regulated retail business primarily through Rate RSE, Rate CNP, Rate ECR, and Rate NDR. In addition, the Alabama PSC issues accounting orders to address current events impacting Alabama Power.

Petition for Certificate of Convenience and Necessity

On June 9, 2020, the Alabama PSC approved in part Alabama Power's petition for a CCN which authorizes Alabama Power to (i) construct an approximately 720-MW combined cycle facility at Alabama Power's Plant Barry (Plant Barry Unit 8), which is expected to be placed in service by the end of 2023, (ii) complete the Autauga Combined Cycle Acquisition, which was approved by the FERC on April 22, 2020 and is expected to close by September 1, 2020, (iii) purchase approximately 240 MWs of combined cycle generation under a long-term PPA expected to begin later in 2020 and (iv) pursue up to approximately 200 MWs of certain demand-side management and distributed energy resource programs.

The Alabama PSC authorized the recovery of actual costs for the construction of Plant Barry Unit 8 up to 5% above the estimated in-service cost of $652 million. In so doing, it recognized the potential for developments that could cause the project costs to exceed the capped amount, in which case Alabama Power would provide documentation to the Alabama PSC to explain and justify potential recovery of the additional costs.

The Alabama PSC further directed that the proposed solar generation of approximately 400 MWs, coupled with battery energy storage systems (solar/battery systems), be evaluated under an existing Renewable Generation Certificate issued by the Alabama PSC in September 2015.

Alabama Power expects to recover all approved costs associated with the CCN through existing rate mechanisms as outlined in Note 2 to the financial statements in Item 8 of the Form 10-K. The Alabama PSC's approval in part of the CCN will be followed by a written order which is subject to any rehearing request or judicial appeal filed within 30 days of the date of such order.

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

Georgia Power

Georgia Power's revenues from regulated retail operations are collected through various rate mechanisms subject to the oversight of the Georgia PSC. Georgia Power currently recovers its costs from the regulated retail business through an alternate rate plan, which includes traditional base tariffs, Demand-Side Management tariffs, the

146


Table of Contents                                Index to Financial Statements

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

Environmental Compliance Cost Recovery tariff, and Municipal Franchise Fee tariffs. In addition, financing costs on certified construction costs of Plant Vogtle Units 3 and 4 are being collected through the NCCR tariff and fuel costs are collected through a separate fuel cost recovery tariff.

Deferral of Incremental COVID-19 Costs

On April 7, 2020 and June 2, 2020, in response to the COVID-19 pandemic, the Georgia PSC approved orders directing Georgia Power to continue its previous, voluntary suspension of customer disconnections through July 14, 2020 and to defer the resulting incremental bad debt as a regulatory asset. On June 16, 2020 and July 7, 2020, the Georgia PSC approved orders establishing a methodology for identifying incremental bad debt and allowing the deferral of other incremental costs associated with the COVID-19 pandemic. The period over which such costs will be recovered is expected to be determined in Georgia Power's next base rate case. At June 30, 2020, the incremental costs deferred totaled approximately $34 million. The ultimate outcome of this matter cannot be determined at this time.

Integrated Resource Plan

On March 5, 2020, the Sierra Club filed a petition for judicial review in the Superior Court of Fulton County to appeal the Georgia PSC's decision in the 2019 ARP allowing Georgia Power to recover compliance costs for CCR AROs. Georgia Power intervened in the appeal on June 22, 2020. The ultimate outcome of this matter cannot be determined at this time.

Fuel Cost Recovery

On May 28, 2020, the Georgia PSC approved a stipulation agreement among Georgia Power, the staff of the Georgia PSC, and certain intervenors to lower total fuel billings by approximately $740 million over a two-year period effective June 1, 2020. In addition, Georgia Power will further lower fuel billings by approximately $44 million under an interim fuel rider effective June 1, 2020 through September 30, 2020. Georgia Power continues to be allowed to adjust its fuel cost recovery rates under an interim fuel rider prior to its next fuel case if the under or over recovered fuel balance exceeds $200 million. Georgia Power is scheduled to file its next fuel case no later than February 28, 2023.

Mississippi Power

Mississippi Power's rates and charges for service to retail customers are subject to the regulatory oversight of the Mississippi PSC. Mississippi Power's rates are a combination of base rates and several separate cost recovery clauses for specific categories of costs. These separate cost recovery clauses address such items as fuel and purchased power, ad valorem taxes, property damage, and the costs of compliance with environmental laws and regulations. Costs not addressed through one of the specific cost recovery clauses are expected to be recovered through Mississippi Power's base rates.

2019 Base Rate Case

On March 17, 2020, the Mississippi PSC approved the Mississippi Power Rate Case Settlement Agreement between Mississippi Power and the Mississippi Public Utilities Staff related to Mississippi Power's base rate case filed in November 2019.

Under the terms of the Mississippi Power Rate Case Settlement Agreement, annual retail rates decreased approximately $16.7 million, or 1.85%, effective for the first billing cycle of April 2020, 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.

Additionally, the approved Mississippi Power Rate Case Settlement Agreement: (i) established common amortization periods of four years for regulatory assets and three years for regulatory liabilities included in the approved revenue requirement, including those related to unprotected deferred income taxes; (ii) established new depreciation rates reflecting an annual increase in depreciation of approximately $10 million; and (iii) excluded

147

AND RESULTS OF OPERATIONS (Continued)

certain compensation costs totaling approximately $3.9 million. It also eliminated separate rates for costs associated with Plant Ratcliffe and energy efficiency initiatives and includes such costs in the PEP, ECO Plan, and ad valorem tax adjustment factor, as applicable. In accordance with the previous order of the Mississippi PSC suspending the operation of PEP and the ECO Plan for 2018 through 2020, Mississippi Power plans to resume PEP proceedings and ECO Plan filings for 2021.

Performance Evaluation Plan

On July 24, 2020, the Mississippi PSC approved Mississippi Power's July 14, 2020 filing of its PEP compliance rate clause reflecting revisions agreed to in the Mississippi Power Rate Case Settlement Agreement. These revisions include, among other things, changing the filing date for the annual PEP rate filing from November of the immediately preceding year to March of the current 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.

Deferral of Incremental COVID-19 Costs

On April 14, 2020 and May 12, 2020, in order to mitigate the economic impact of the COVID-19 pandemic on customers, the Mississippi PSC approved orders directing Mississippi Power to continue its previous, voluntary suspension of customer disconnections through May 25, 2020 and to defer as a regulatory asset all necessary and reasonable incremental costs or expenses to plan, prepare, stage, or react to protect and keep safe its employees and customers, and to reliably operate its utility system during the COVID-19 pandemic. The period over which such costs will be recovered is expected to be determined in a future PEP filing. At June 30, 2020, the incremental costs deferred totaled approximately $2 million. The ultimate outcome of this matter cannot be determined at this time.

Municipal and Rural Associations Tariff

On June 25, 2020, the FERC accepted Mississippi Power's April 27, 2020 request for an increase in wholesale base revenues under the MRA tariff as agreed upon in a settlement agreement reached with its wholesale customers. The MRA settlement agreement resulted in a $2 million annual increase in base rates effective June 1, 2020.

Southern Company Gas

The natural gas distribution utilities are subject to regulation and oversight by their respective state regulatory agencies for the rates charged to their customers and other matters. With the exception of Atlanta Gas Light, which does not sell natural gas to end-use customers, the natural gas distribution utilities are authorized by the relevant regulatory agencies in the states in which they serve to use natural gas cost recovery mechanisms that adjust rates to reflect changes in the wholesale cost of natural gas and ensure recovery of all costs prudently incurred in purchasing natural gas for customers. Natural gas cost recovery revenues are adjusted for differences in actual recoverable natural gas costs and amounts billed in current regulated rates. Changes in the billing factor will not have a significant effect on revenues or net income, but will affect cash flows. In addition to natural gas cost recovery mechanisms, there are other cost recovery mechanisms, such as regulatory riders, which vary by utility but allow recovery of certain costs, such as those related to infrastructure replacement programs, as well as environmental remediation, energy efficiency plans, and bad debt.

The natural gas distribution utilities have various regulatory mechanisms to recover bad debt expense, which will mitigate potential increases in bad debt expense as a result of the COVID-19 pandemic. Nicor Gas fully recovers its bad debt expenses, both the gas and non-gas portions, through its purchased gas adjustment mechanism and separate bad debt rider. Virginia Natural Gas and Chattanooga Gas recover the gas portion of bad debt expense through their purchased gas adjustment mechanisms and the non-gas portion of bad debt expense through their base rates in accordance with established benchmarks. Atlanta Gas Light does not have material bad debt expense because its receivables are from Marketers, rather than end-use customers. Its tariff allows it to obtain credit security support from the Marketers in an amount equal to at least two times their estimated highest bill.

Rate Proceedings

On June 1, 2020, Virginia Natural Gas filed a general rate case with the Virginia Commission seeking an increase in rates of $49.6 million primarily to recover investments and increased costs associated with infrastructure, technology, and workforce development. The requested increase is based on a projected 12-month test year beginning November 1, 2020, a ROE of 10.35%, and an equity ratio of 54%. Rate adjustments are expected to be effective November 1, 2020, subject to refund. The Virginia Commission is expected to rule on the requested increase in the second quarter 2021.

On July 1, 2020, Atlanta Gas Light filed its 2020 GRAM filing with the Georgia PSC. The filing requests an annual base rate increase of $37.6 million based on the projected 12-month period beginning January 1, 2021, which does not exceed the 5% limitation established by the Georgia PSC in its December 2019 approval of Atlanta Gas Light's general base rate case. Resolution of the 2020 GRAM filing is expected by December 31, 2020, with rates effective January 1, 2021.

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

Deferral of Incremental COVID-19 Costs

Atlanta Gas Light

On April 30, 2020, in response to the COVID-19 pandemic, the Georgia PSC approved orders directing Atlanta Gas Light to continue its previous, voluntary suspension of customer disconnections. On June 22, 2020, the Georgia PSC ordered Atlanta Gas Light to resume customer disconnections beginning July 1, 2020, with exceptions for customers still covered by a shelter-in-place order. The orders provide the Marketers, including SouthStar, with a mechanism to receive credits from Atlanta Gas Light for the base rates it charged to the Marketers of non-paying customers during the suspension. Atlanta Gas Light expects to recover these credits through the annual revenue true-up process within its 2021 GRAM filing, which would impact rates effective January 1, 2022. The ultimate outcome of this matter cannot be determined at this time.

Nicor Gas

On March 18, 2020, the Illinois Commission issued an order directing utilities to cease disconnections for non-payment and to suspend the imposition of late payment fees or penalties until the Governor of Illinois announces the end of the COVID-19 state of emergency. In response to this order, on March 27, 2020, Nicor Gas and other utilities in Illinois filed their plans seeking cost recovery and more flexible credit and collection plans.

On June 18, 2020, the Illinois Commission approved a stipulation pursuant to which the utilities will provide more flexible credit and collection procedures to assist customers with financial hardship and which authorizes a special purpose rider for recovery of the following COVID-19 pandemic-related impacts: incremental costs directly associated with the COVID-19 pandemic, net of the offset for COVID-19 pandemic-related credits received, foregone late fees, foregone reconnection charges, and the costs associated with a bill payment assistance program. The special purpose rider is proposed to be effective on October 1, 2020 and continue over a 24-month period. At June 30, 2020, Nicor Gas' related regulatory asset was $12 million. The ultimate outcome of this matter cannot be determined at this time.

Virginia Natural Gas

In response to the COVID-19 pandemic, the Virginia Commission issued orders requiring Virginia Natural Gas to suspend disconnections beginning on March 16, 2020 and also to suspend late payment and reconnection fees beginning on April 9, 2020, both of which continue in effect through August 31, 2020. On April 29, 2020, the Virginia Commission authorized Virginia Natural Gas to defer the following COVID-19 pandemic-related costs as a regulatory asset: incremental uncollectible expense incurred, suspended late fees, suspended reconnection charges, carrying costs, and other incremental prudently incurred costs associated with the COVID-19 pandemic. Specific recovery of the amounts deferred in a regulatory asset will be addressed in a future rate proceeding. At June 30,

2020, Virginia Natural Gas' related regulatory asset was $1 million. The ultimate outcome of this matter cannot be determined at this time.

Construction Programs

Overview

The Subsidiary Registrants are engaged in continuous construction programs to accommodate existing and estimated future loads on their respective systems. The Southern Company system intends to continue its strategy of developing and constructing new electric generating facilities, expanding and improving the electric transmission and electric and natural gas distribution systems, and undertaking projects to comply with environmental laws and regulations.

For the traditional electric operating companies, major generation construction projects are subject to state PSC approval in order to be included in retail rates. The largest construction project currently underway in the Southern Company system is Plant Vogtle Units 3 and 4. See "Nuclear Construction" herein for additional information. Also see Note 2 to the financial statements in Item 8 of the Form 10-K and Note (B) to the Condensed Financial Statements herein under "Alabama Power" for information regarding Alabama Power's construction of Plant Barry Unit 8.

While Southern Power generally constructs and acquires generation assets covered by long-term PPAs, any uncontracted capacity could negatively affect future earnings. See "Southern Power" herein, "Acquisitions and Dispositions – Southern Power" herein, and Note (K) to the Condensed Financial Statements under "Southern Power" herein, as well as Note 15 to the financial statements under "Southern Power" in Item 8 of the Form 10-K, for additional information about costs relating to Southern Power's acquisitions that involve construction of renewable energy facilities.

Southern Company Gas is engaged in various infrastructure improvement programs designed to update or expand the natural gas distribution systems of the natural gas distribution utilities to improve reliability and meet operational flexibility and growth. The natural gas distribution utilities recover their investment and a return associated with these infrastructure programs through their regulated rates. See "Southern Company Gas" herein for additional information regarding infrastructure improvement programs at the natural gas distribution utilities and the PennEast Pipeline construction project.

See FINANCIAL CONDITION AND LIQUIDITY – "Capital Requirements and Contractual Obligations" herein for additional information regarding the Registrants' capital requirements for their construction programs.

Nuclear Construction

See Note 2 to the financial statements under "Georgia Power – Nuclear Construction" in Item 8 of the Form 10-K for additional information regarding Georgia Power's construction of Plant Vogtle Units 3 and 4, the joint ownership agreements and related funding agreement, VCM reports, and the NCCR tariff.

In 2009, the Georgia PSC certified construction of Plant Vogtle Units 3 and 4, in which Georgia Power holds a 45.7% ownership interest. In 2012, the NRC issued the related combined construction and operating licenses, which allowed full construction of the two AP1000 nuclear units (with electric generating capacity of approximately 1,100 MWs each) and related facilities to begin. Until March 2017, construction on Plant Vogtle Units 3 and 4 continued under the Vogtle 3 and 4 Agreement, which was a substantially fixed price agreement. In March 2017, the EPC Contractor filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code.

In connection with the EPC Contractor's bankruptcy filing, Georgia Power, acting for itself and as agent for the other Vogtle Owners, entered into several transitional arrangements to allow construction to continue. In July 2017, Georgia Power, acting for itself and as agent for the other Vogtle Owners, entered into the Vogtle Services Agreement, whereby Westinghouse provides facility design and engineering services, procurement and technical support, and staff augmentation on a time and materials cost basis. The Vogtle Services Agreement provides that it will continue until the start-up and testing of Plant Vogtle Units 3 and 4 are complete and electricity is generated and

150

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

sold from both units. The Vogtle Services Agreement is terminable by the Vogtle Owners upon 30 days' written notice.

In October 2017, Georgia Power, acting for itself and as agent for the other Vogtle Owners, executed the Bechtel Agreement, a cost reimbursable plus fee arrangement, whereby Bechtel is reimbursed for actual costs plus a base fee and an at-risk fee, which is subject to adjustment based on Bechtel's performance against cost and schedule targets. Each Vogtle Owner is severally (not jointly) liable for its proportionate share, based on its ownership interest, of all amounts owed to Bechtel under the Bechtel Agreement. The Vogtle Owners may terminate the Bechtel Agreement at any time for their convenience, provided that the Vogtle Owners will be required to pay amounts related to work performed prior to the termination (including the applicable portion of the base fee), certain termination-related costs, and, at certain stages of the work, the applicable portion of the at-risk fee. Bechtel may terminate the Bechtel Agreement under certain circumstances, including certain Vogtle Owner suspensions of work, certain breaches of the Bechtel Agreement by the Vogtle Owners, Vogtle Owner insolvency, and certain other events.

See Note 8 to the financial statements under "Long-term Debt – DOE Loan Guarantee Borrowings" in Item 8 of the Form 10-K for information on the Amended and Restated Loan Guarantee Agreement, including applicable covenants, events of default, mandatory prepayment events, and conditions to borrowing.

Cost and Schedule

Georgia Power's approximate proportionate share of the remaining estimated capital cost to complete Plant Vogtle Units 3 and 4 by the expected in-service dates of November 2021 and November 2022, respectively, is as follows:

(in billions)
Base project capital cost forecast^(a)(b)^ $ 8.4
Construction contingency estimate 0.1
Total project capital cost forecast^(a)(b)^ 8.5
Net investment as of June 30, 2020^(b)^ (6.6 )
Remaining estimate to complete^(a)^ $ 1.9
(a) Excludes financing costs expected to be capitalized through AFUDC of approximately $260 million, of which $52 million had been accrued through June 30, 2020.
--- ---
(b) Net of $1.7 billion received from Toshiba under the Guarantee Settlement Agreement and approximately $188 million in related customer refunds.
--- ---

Georgia Power estimates that its financing costs for construction of Plant Vogtle Units 3 and 4 will total approximately $3.0 billion, of which $2.4 billion had been incurred through June 30, 2020.

As part of its ongoing processes, Southern Nuclear continues to evaluate cost and schedule forecasts on a regular basis to incorporate current information available, particularly in the areas of engineering support, commodity installation, system turnovers, and workforce statistics.

During the second quarter 2020, approximately $194 million of construction contingency was assigned to the base capital cost forecast for cost risks including, among other things, construction productivity, including the April 2020 reduction in workforce designed to mitigate impacts of the COVID-19 pandemic described below, field support, subcontracts, engineering resources, and procurement. The second quarter 2020 assignment of contingency exceeded the remaining balance of the $366 million construction contingency originally established in the second quarter 2018 by approximately $34 million. Through June 30, 2020, assignments of contingency for cost risks also have included, among other factors, construction productivity; craft labor incentives; adding resources for supervision, field support, project management, initial test program, start-up, and operations and engineering support; subcontracts; and procurement. As a result of these factors, Southern Nuclear recommended establishing additional construction contingency, of which Georgia Power's share is approximately $115 million, for further potential risks including, among other factors, construction productivity and expected impacts of the COVID-19

151

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

pandemic; adding resources for supervision, field support, project management, initial test program, start-up, and operations and engineering support; subcontracts; and procurement.

After considering the significant level of uncertainty that exists regarding the future recoverability of these costs since the ultimate outcome of these matters is subject to the outcome of future assessments by management, as well as Georgia PSC decisions in future regulatory proceedings, Georgia Power recorded a total pre-tax charge to income of $149 million ($111 million after tax) for the increase in the total project capital cost forecast as of June 30, 2020. As and when these amounts are spent, Georgia Power may request the Georgia PSC to evaluate those expenditures for rate recovery.

In April 2019, Southern Nuclear established aggressive target values for monthly construction production and system turnover activities as part of a strategy to maintain and, where possible, build margin to the regulatory-approved in-service dates of November 2021 for Unit 3 and November 2022 for Unit 4. Through early 2020, the project faced challenges with the April 2019 aggressive strategy targets including, but not limited to, electrical and pipefitting labor productivity and work package closure rates, which resulted in a backlog of activities and completion percentages below the April 2019 aggressive strategy targets.

In February 2020, Southern Nuclear updated its cost and schedule forecast, which, at that time, did not change the total project capital cost forecast and confirmed the expected in-service dates of November 2021 for Unit 3 and November 2022 for Unit 4. This update included initiatives to improve productivity while refining and extending system turnover plans and certain near-term milestone dates. Other milestone dates did not change. Achievement of the February 2020 aggressive site work plan relied on meeting increased monthly production and activity target values during 2020.

In mid-March 2020, Southern Nuclear began implementing policies and procedures designed to mitigate the risk of transmission of COVID-19 at the construction site, including worker distancing measures, isolating individuals who have tested positive for COVID-19, are showing symptoms consistent with COVID-19, are being tested for COVID-19, or have been in close contact with such persons, requiring self-quarantine, and adopting additional precautionary measures.

In April 2020, Georgia Power, acting for itself and as agent for the other Vogtle Owners, announced a reduction in workforce at Plant Vogtle Units 3 and 4, which totaled approximately 20% of the then-existing site workforce. This reduction in workforce was a mitigation action intended to address the impact of the COVID-19 pandemic on the Plant Vogtle Units 3 and 4 workforce and construction site, including challenges with labor productivity that were exacerbated by the impact of the COVID-19 pandemic. The April 2020 workforce reduction was intended to provide operational efficiencies by increasing productivity of the remaining workforce and reducing workforce fatigue and absenteeism. Further, it was also intended to allow for increased social distancing by the workforce and facilitate compliance with the recommendations from the Centers for Disease Control and Prevention. The April 2020 workforce reduction did reduce absenteeism, providing an improvement in operational efficiency and allowing for increased social distancing. From the initial peak in April 2020, the number of active cases at the site declined significantly during May and early June, but began increasing again in mid-June and continues to impact productivity levels and pace of activity completion. As a result of these factors, overall production improvements have not been achieved at the levels anticipated, contributing to the allocation of, and increase in, construction contingency described above. Through mid-July 2020, Unit 3 mechanical, electrical, and subcontract activities continued to build a backlog to Southern Nuclear's February 2020 aggressive site work plan.

To address these issues, in July 2020, Southern Nuclear updated its aggressive site work plan for both Unit 3 and Unit 4. To meet the targets in the July 2020 aggressive site work plan, absenteeism rates must continue to normalize and overall construction productivity and production levels, including subcontractors, must significantly improve and be sustained above pre-pandemic levels. In addition, appropriate levels of craft laborers, particularly electrical and pipefitter craft labor, must be added and maintained. While Southern Nuclear's July 2020 aggressive site work plan extended milestone dates from the February 2020 aggressive site work plan, Georgia Power still expects to achieve the regulatory-approved in-service dates of November 2021 and November 2022 for Plant Vogtle Units 3

152

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

and 4, respectively. Southern Nuclear and Georgia Power continue to believe that pursuit of an aggressive site work plan is an appropriate strategy to achieve completion of the units by their regulatory-approved in-service dates.

As construction, including subcontract work, continues and testing and system turnover activities increase, challenges with management of contractors and vendors; subcontractor performance; supervision of craft labor and related productivity, particularly in the installation of electrical, mechanical, and instrumentation and controls commodities, ability to attract and retain craft labor, and/or related cost escalation; procurement, fabrication, delivery, assembly, installation, system turnover, and the initial testing and start-up, including any required engineering changes or any remediation related thereto, of plant systems, structures, or components (some of which are based on new technology that only within the last few years began initial operation in the global nuclear industry at this scale), any of which may require additional labor and/or materials; or other issues could arise and change the projected schedule and estimated cost.

In addition, the continuing effects of the COVID-19 pandemic could further disrupt or delay construction, testing, supervisory, and support activities at Plant Vogtle Units 3 and 4. Georgia Power's proportionate share of the estimated incremental cost associated with COVID-19 mitigation actions and impacts on construction productivity is currently estimated to be between $70 million and $115 million, which is included in the total project capital cost forecast and assumes (i) absenteeism rates continue to normalize and (ii) the intended productivity efficiencies and production targets assumed in Southern Nuclear's July 2020 aggressive site work plan are realized in the coming months. However, the ultimate impact of the COVID-19 pandemic on the construction schedule and budget for Plant Vogtle Units 3 and 4 cannot be determined at this time.

There have been technical and procedural challenges to the construction and licensing of Plant Vogtle Units 3 and 4 at the federal and state level and additional challenges may arise. Processes are in place that are designed to assure compliance with the requirements specified in the Westinghouse Design Control Document and the combined construction and operating licenses, including inspections by Southern Nuclear and the NRC that occur throughout construction. As a result of such compliance processes, certain license amendment requests have been filed and approved or are pending before the NRC. Various design and other licensing-based compliance matters, including the timely submittal by Southern Nuclear of the ITAAC documentation for each unit and the related reviews and approvals by the NRC necessary to support NRC authorization to load fuel, may arise, which may result in additional license amendments or require other resolution. As part of the aggressive site work plan, in January 2020, Southern Nuclear notified the NRC of its intent to load fuel in 2020. On May 11, 2020, the Blue Ridge Environmental Defense League filed a petition with the NRC that challenges a license amendment request. On June 15, 2020, the NRC issued an appealable order rejecting Nuclear Watch South's April 20, 2020 petition requesting a hearing and challenging the closure of certain ITAAC. If any license amendment requests or other licensing-based compliance issues are not resolved in a timely manner, there may be delays in the project schedule that could result in increased costs.

The ultimate outcome of these matters cannot be determined at this time. However, any extension of the regulatory-approved project schedule is currently estimated to result in additional base capital costs of approximately $50 million per month, based on Georgia Power's ownership interests, and AFUDC of approximately $10 million per month. While Georgia Power is not precluded from seeking recovery of any future capital cost forecast increase, management will ultimately determine whether or not to seek recovery. Any further changes to the capital cost forecast that are not expected to be recoverable through regulated rates will be required to be charged to income and such charges could be material.

Joint Owner Contracts

In November 2017, the Vogtle Owners entered into an amendment to their joint ownership agreements for Plant Vogtle Units 3 and 4 to provide for, among other conditions, additional Vogtle Owner approval requirements. Effective in August 2018, the Vogtle Owners further amended the joint ownership agreements to clarify and provide procedures for certain provisions of the joint ownership agreements related to adverse events that require the vote of the holders of at least 90% of the ownership interests in Plant Vogtle Units 3 and 4 to continue construction (as amended, and together with the November 2017 amendment, the Vogtle Joint Ownership Agreements). The Vogtle

Joint Ownership Agreements also confirm that the Vogtle Owners' sole recourse against Georgia Power or Southern Nuclear for any action or inaction in connection with their performance as agent for the Vogtle Owners is limited to removal of Georgia Power and/or Southern Nuclear as agent, except in cases of willful misconduct.

As a result of an increase in the total project capital cost forecast and Georgia Power's decision not to seek rate recovery of the increase in the base capital costs in conjunction with the nineteenth VCM report in 2018, the holders of at least 90% of the ownership interests in Plant Vogtle Units 3 and 4 were required to vote to continue construction. In September 2018, the Vogtle Owners unanimously voted to continue construction of Plant Vogtle Units 3 and 4.

Amendments to the Vogtle Joint Ownership Agreements

In connection with the vote to continue construction, Georgia Power entered into (i) a binding term sheet (Vogtle Owner Term Sheet) with the other Vogtle Owners and MEAG Power's wholly-owned subsidiaries MEAG Power SPVJ, LLC (MEAG SPVJ), MEAG Power SPVM, LLC (MEAG SPVM), and MEAG Power SPVP, LLC (MEAG SPVP) to take certain actions which partially mitigate potential financial exposure for the other Vogtle Owners, including additional amendments to the Vogtle Joint Ownership Agreements and the purchase of PTCs from the other Vogtle Owners at pre-established prices, and (ii) a term sheet (MEAG Term Sheet) with MEAG Power and MEAG SPVJ to provide up to $300 million of funding with respect to MEAG SPVJ's ownership interest in Plant Vogtle Units 3 and 4 under certain circumstances. In January 2019, Georgia Power, MEAG Power, and MEAG SPVJ entered into an agreement to implement the provisions of the MEAG Term Sheet. In February 2019, Georgia Power, the other Vogtle Owners, and MEAG Power's wholly-owned subsidiaries MEAG SPVJ, MEAG SPVM, and MEAG SPVP entered into certain amendments to the Vogtle Joint Ownership Agreements to implement the provisions of the Vogtle Owner Term Sheet (Global Amendments).

As previously disclosed, pursuant to the Global Amendments: (i) each Vogtle Owner must pay its proportionate share of qualifying construction costs for Plant Vogtle Units 3 and 4 based on its ownership percentage up to the estimated cost at completion (EAC) for Plant Vogtle Units 3 and 4 which formed the basis of Georgia Power's forecast of $8.4 billion in the nineteenth VCM plus $800 million; (ii) Georgia Power will be responsible for 55.7% of actual qualifying construction costs between $800 million and $1.6 billion over the EAC in the nineteenth VCM (resulting in $80 million of potential additional costs to Georgia Power), with the remaining Vogtle Owners responsible for 44.3% of such costs pro rata in accordance with their respective ownership interests; and (iii) Georgia Power will be responsible for 65.7% of qualifying construction costs between $1.6 billion and $2.1 billion over the EAC in the nineteenth VCM (resulting in a further $100 million of potential additional costs to Georgia Power), with the remaining Vogtle Owners responsible for 34.3% of such costs pro rata in accordance with their respective ownership interests. If the EAC is revised and exceeds the EAC in the nineteenth VCM by more than $2.1 billion, each of the other Vogtle Owners will have a one-time option at the time the project budget forecast is so revised to tender a portion of its ownership interest to Georgia Power in exchange for Georgia Power's agreement to pay 100% of such Vogtle Owner's remaining share of total construction costs in excess of the EAC in the nineteenth VCM plus $2.1 billion.

In addition, pursuant to the Global Amendments, the holders of at least 90% of the ownership interests in Plant Vogtle Units 3 and 4 must vote to continue construction if certain adverse events occur, including, among other events: (i) the bankruptcy of Toshiba; (ii) the termination or rejection in bankruptcy of certain agreements, including the Vogtle Services Agreement, the Bechtel Agreement, or the agency agreement with Southern Nuclear; (iii) Georgia Power's public announcement of its intention not to submit for rate recovery any portion of its investment in Plant Vogtle Units 3 and 4 or the Georgia PSC determines that any of Georgia Power's costs relating to the construction of Plant Vogtle Units 3 and 4 will not be recovered in retail rates, excluding any additional amounts paid by Georgia Power on behalf of the other Vogtle Owners pursuant to the Global Amendments described above and the first 6% of costs during any six-month VCM reporting period that are disallowed by the Georgia PSC for recovery, or for which Georgia Power elects not to seek cost recovery, through retail rates; and (iv) an incremental extension of one year or more over the most recently approved schedule.

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

Regulatory Matters

In 2009, the Georgia PSC voted to certify construction of Plant Vogtle Units 3 and 4 with a certified capital cost of $4.418 billion. In addition, in 2009 the Georgia PSC approved inclusion of the Plant Vogtle Units 3 and 4 related CWIP accounts in rate base, and the State of Georgia enacted the Georgia Nuclear Energy Financing Act, which allows Georgia Power to recover financing costs for Plant Vogtle Units 3 and 4. Financing costs are recovered on all applicable certified costs through annual adjustments to the NCCR tariff up to the certified capital cost of $4.418 billion. At June 30, 2020, Georgia Power had recovered approximately $2.4 billion of financing costs. Financing costs related to capital costs above $4.418 billion are being recognized through AFUDC and are expected to be recovered through retail rates over the life of Plant Vogtle Units 3 and 4; however, Georgia Power will not record AFUDC related to any capital costs in excess of the total deemed reasonable by the Georgia PSC (currently $7.3 billion) and not requested for rate recovery. In December 2019, the Georgia PSC approved Georgia Power's request to decrease the NCCR tariff by $62 million annually, effective January 1, 2020.

Georgia Power is required to file semi-annual VCM reports with the Georgia PSC by February 28 and August 31 of each year. In 2013, in connection with the eighth VCM report, the Georgia PSC approved a stipulation between Georgia Power and the staff of the Georgia PSC to waive the requirement to amend the Plant Vogtle Units 3 and 4 certificate in accordance with the 2009 certification order until the completion of Plant Vogtle Unit 3, or earlier if deemed appropriate by the Georgia PSC and Georgia Power.

In 2016, the Georgia PSC voted to approve a settlement agreement (Vogtle Cost Settlement Agreement) resolving certain prudency matters in connection with the fifteenth VCM report. In December 2017, the Georgia PSC voted to approve (and issued its related order on January 11, 2018) Georgia Power's seventeenth VCM report and modified the Vogtle Cost Settlement Agreement. The Vogtle Cost Settlement Agreement, as modified by the January 11, 2018 order, resolved the following regulatory matters related to Plant Vogtle Units 3 and 4: (i) none of the $3.3 billion of costs incurred through December 31, 2015 and reflected in the fourteenth VCM report should be disallowed from rate base on the basis of imprudence; (ii) the Contractor Settlement Agreement was reasonable and prudent and none of the amounts paid pursuant to the Contractor Settlement Agreement should be disallowed from rate base on the basis of imprudence; (iii) (a) capital costs incurred up to $5.68 billion would be presumed to be reasonable and prudent with the burden of proof on any party challenging such costs, (b) Georgia Power would have the burden to show that any capital costs above $5.68 billion were prudent, and (c) a revised capital cost forecast of $7.3 billion (after reflecting the impact of payments received under the Guarantee Settlement Agreement and related customer refunds) was found reasonable; (iv) construction of Plant Vogtle Units 3 and 4 should be completed, with Southern Nuclear serving as project manager and Bechtel as primary contractor; (v) approved and deemed reasonable Georgia Power's revised schedule placing Plant Vogtle Units 3 and 4 in service in November 2021 and November 2022, respectively; (vi) confirmed that the revised cost forecast does not represent a cost cap and that prudence decisions on cost recovery will be made at a later date, consistent with applicable Georgia law; (vii) reduced the ROE used to calculate the NCCR tariff (a) from 10.95% (the ROE rate setting point authorized by the Georgia PSC in the 2013 ARP) to 10.00% effective January 1, 2016, (b) from 10.00% to 8.30%, effective January 1, 2020, and (c) from 8.30% to 5.30%, effective January 1, 2021 (provided that the ROE in no case will be less than Georgia Power's average cost of long-term debt); (viii) reduced the ROE used for AFUDC equity for Plant Vogtle Units 3 and 4 from 10.00% to Georgia Power's average cost of long-term debt, effective January 1, 2018; and (ix) agreed that upon Unit 3 reaching commercial operation, retail base rates would be adjusted to include carrying costs on those capital costs deemed prudent in the Vogtle Cost Settlement Agreement. The January 11, 2018 order also stated that if Plant Vogtle Units 3 and 4 are not commercially operational by June 1, 2021 and June 1, 2022, respectively, the ROE used to calculate the NCCR tariff will be further reduced by 10 basis points each month (but not lower than Georgia Power's average cost of long-term debt) until the respective Unit is commercially operational. The ROE reductions negatively impacted earnings by approximately $75 million in 2019 and are estimated to have negative earnings impacts of approximately $145 million, $255 million, and $200 million in 2020, 2021, and 2022, respectively. In its January 11, 2018 order, the Georgia PSC also stated if other conditions change and assumptions upon which Georgia Power's seventeenth VCM report are based do not materialize, the Georgia PSC reserved the right to reconsider the decision to continue construction.

AND RESULTS OF OPERATIONS (Continued)

In February 2018, Georgia Interfaith Power & Light, Inc. (GIPL) and Partnership for Southern Equity, Inc. (PSE) filed a petition appealing the Georgia PSC's January 11, 2018 order with the Fulton County Superior Court. In March 2018, Georgia Watch filed a similar appeal to the Fulton County Superior Court for judicial review of the Georgia PSC's decision and denial of Georgia Watch's motion for reconsideration. In December 2018, the Fulton County Superior Court granted Georgia Power's motion to dismiss the two appeals. In January 2019, GIPL, PSE, and Georgia Watch filed an appeal of this decision with the Georgia Court of Appeals. In October 2019, the Georgia Court of Appeals issued an opinion affirming the Fulton County Superior Court's ruling that the Georgia PSC's January 11, 2018 order was not a final, appealable decision. In addition, the Georgia Court of Appeals remanded the case to the Fulton County Superior Court to clarify its ruling as to whether the petitioners showed that review of the Georgia PSC's final order would not provide them an adequate remedy. On April 21, 2020, the Fulton County Superior Court granted Georgia Power's motion to dismiss the two appeals. The petitioners filed a notice of appeal of the dismissal on May 20, 2020. Georgia Power believes the petitions have no merit; however, an adverse outcome in the litigation combined with subsequent adverse action by the Georgia PSC could have a material impact on Southern Company's and Georgia Power's results of operations, financial condition, and liquidity.

The Georgia PSC has approved 21 VCM reports covering the periods through June 30, 2019, including total construction capital costs incurred through that date of $6.7 billion (before $1.7 billion of payments received under the Guarantee Settlement Agreement and approximately $188 million in related customer refunds). On August 18, 2020, the Georgia PSC is scheduled to vote on Georgia Power's twenty-second VCM report, which requested approval of $674 million of construction capital costs incurred from July 1, 2019 through December 31, 2019.

Georgia Power expects to file its twenty-third VCM report with the Georgia PSC by August 31, 2020, which will reflect the revised capital cost forecast discussed above and request approval of $701 million of construction capital costs incurred from January 1, 2020 through June 30, 2020.

See RISK FACTORS in Item 1A herein and in the Form 10-K for a discussion of certain risks associated with the licensing, construction, and operation of nuclear generating units, including potential impacts that could result from a major incident at a nuclear facility anywhere in the world.

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

Southern Power

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Construction Programs – Southern Power" in Item 7 of the Form 10-K and FINANCIAL CONDITION AND LIQUIDITY – "Capital Requirements and Contractual Obligations" herein for additional information.

During the six months ended June 30, 2020, Southern Power completed construction of and placed in service the Reading wind facility, continued construction of the Skookumchuck wind facility, and commenced construction of the Garland and Tranquillity battery energy storage facilities. Total aggregate construction costs, excluding acquisition costs, are expected to be between $475 million and $545 million for the facilities under construction. At June 30, 2020, total costs of construction incurred for these projects were $232 million and are included in CWIP. The ultimate outcome of these matters cannot be determined at this time.

Infrastructure Replacement Programs and Capital Projects

In addition to capital expenditures recovered through base rates by each of the natural gas distribution utilities, Nicor Gas and Virginia Natural Gas have separate rate riders that provide timely recovery of capital expenditures for specific infrastructure replacement programs. Infrastructure expenditures incurred under these programs in the first six months of 2020 were as follows:

Utility Program Year-to-Date 2020
(in millions)
Nicor Gas Investing in Illinois $ 158
Virginia Natural Gas Steps to Advance Virginia's Energy (SAVE) 25
Total $ 183

In December 2019, Virginia Natural Gas filed an application with the Virginia Commission for a 24.1-mile header improvement project to improve resiliency and increase the supply of natural gas delivered to energy suppliers, including Virginia Natural Gas. On June 26, 2020, the Virginia Commission issued an order requiring Virginia Natural Gas to submit additional information by December 31, 2020 related to the financing plans of the project's primary customer before ruling on the December 2019 application. The ultimate outcome of this matter cannot be determined at this time.

Pipeline Construction Projects

On March 24, 2020, Southern Company Gas completed the sale of its interest in Atlantic Coast Pipeline. See Note (K) to the Condensed Financial Statements under "Southern Company Gas" herein for additional information.

On February 20, 2020, the FERC approved a two-year extension for PennEast Pipeline to complete the project by January 19, 2022.

In September 2019, an appellate court ruled that the PennEast Pipeline does not have federal eminent domain authority over lands in which a state has property rights interests. On June 29, 2020, the U.S. Supreme Court requested the U.S. Solicitor General to provide an opinion on PennEast Pipeline's petition for a writ of certiorari seeking its review of the appellate court's decision.

Expected project costs related to the PennEast Pipeline for Southern Company Gas total approximately $300 million, excluding financing costs. The ultimate outcome of the PennEast Pipeline construction project cannot be determined at this time; however, any work delays, whether caused by judicial or regulatory action, abnormal weather, or other conditions, may result in additional cost or schedule modifications or, ultimately, in project cancellation, any of which could result in impairment of Southern Company Gas' investment and could have a significant impact on Southern Company's financial statements and a material impact on Southern Company Gas' financial statements.

See Notes 3 and 7 to the financial statements in Item 8 of the Form 10-K and Note (E) to the Condensed Financial Statements herein under "Southern Company Gas" for additional information.

Generally, under the solar and wind generation PPAs, the purchasing party retains the right to keep or resell the renewable energy credits.

During the first quarter 2020, Southern Power received $15 million from Pacific Gas & Electric Company (PG&E) in accordance with a November 2019 bankruptcy court order granting payment of certain transmission interconnections. PG&E emerged from bankruptcy on July 1, 2020 and Southern Power's PPAs and transmission interconnection agreements continue in effect unchanged.

Tax Matters

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Income Tax Matters" in Item 7 of the Form 10-K and Note (G) to the Condensed Financial Statements herein for additional information.

On March 18, 2020 and March 27, 2020, respectively, the Families First Coronavirus Response Act and the Coronavirus Aid, Relief, and Economic Security Act were signed into law. Both acts include provisions intended to provide stability and support for individuals and businesses in response to the COVID-19 pandemic. Southern Company continues to evaluate these provisions, including those related to payroll tax deferrals and employee retention credits; however, they are not expected to have a material impact on the Registrants' financial statements.

On March 20, 2020 and April 9, 2020, the Treasury Department and the Internal Revenue Service issued Notices 2020-18 and 2020-23, respectively, providing relief to taxpayers by postponing to July 15, 2020 a variety of tax form filings and payment obligations that were due before July 15, 2020. Associated interest, additions to tax, and penalties for late filing or late payment were also suspended until July 16, 2020. These provisions had a modest

positive impact on the Registrants' liquidity. However, Southern Power's expected utilization of tax credits in the first half of 2020 was delayed until July 15, 2020.

General Litigation Matters

The Registrants are involved in various other matters being litigated and regulatory matters that could affect future earnings. The ultimate outcome of such pending or potential litigation or regulatory matters against each Registrant and any subsidiaries cannot be determined at this time; however, for current proceedings not specifically reported herein or in Notes (B) and (C) to the Condensed Financial Statements herein, management does not anticipate that the ultimate liabilities, if any, arising from such current proceedings would have a material effect on such Registrant's financial statements. See Notes (B) and (C) to the Condensed Financial Statements for a discussion of various other contingencies, regulatory matters, and other matters being litigated which may affect future earnings potential.

The Registrants believe the pending legal challenges discussed below have no merit; however, the ultimate outcome of these matters cannot be determined at this time.

Southern Company

In January 2017, a securities class action complaint was filed in the U.S. District Court for the Northern District of Georgia by Monroe County Employees' Retirement System on behalf of all persons who purchased shares of Southern Company's common stock between April 25, 2012 and October 29, 2013. The complaint names as defendants Southern Company, certain of its current and former officers, and certain former Mississippi Power officers and alleges that the defendants made materially false and misleading statements regarding the Kemper County energy facility in violation of certain provisions under the Securities Exchange Act of 1934, as amended. The complaint seeks, among other things, compensatory damages and litigation costs and attorneys' fees. In 2017, the plaintiffs filed an amended complaint that provided additional detail about their claims, increased the purported class period by one day, and added certain other former Mississippi Power officers as defendants. Also in 2017, the defendants filed a motion to dismiss the plaintiffs' amended complaint with prejudice, to which the plaintiffs filed an opposition. In 2018, the court issued an order dismissing certain claims against certain officers of Southern Company and Mississippi Power and dismissing the allegations related to a number of the statements that plaintiffs challenged as being false or misleading. In 2018, the court denied the defendants' motion for reconsideration and also denied a motion to certify the issue for interlocutory appeal. In the third quarter 2019, the court certified the plaintiffs' proposed class and the defendants filed a petition for interlocutory appeal of the class certification order with the U.S. Court of Appeals for the Eleventh Circuit. In December 2019, the U.S. District Court for the Northern District of Georgia entered an order staying all deadlines in the case pending mediation. The stay automatically expired on March 31, 2020; however, in light of the COVID-19 pandemic, the U.S. District Court for the Northern District of Georgia vacated all existing discovery deadlines until June 15, 2020. On June 30, 2020, the court entered a revised scheduling order, which resumed discovery and set out remaining case deadlines.

In February 2017, Jean Vineyard and Judy Mesirov each filed a shareholder derivative lawsuit in the U.S. District Court for the Northern District of Georgia. Each of these lawsuits names as defendants Southern Company, certain of its directors, certain of its current and former officers, and certain former Mississippi Power officers. In 2017, these two shareholder derivative lawsuits were consolidated in the U.S. District Court for the Northern District of Georgia. The complaints allege that the defendants caused Southern Company to make false or misleading statements regarding the Kemper County energy facility cost and schedule. Further, the complaints allege that the defendants were unjustly enriched and caused the waste of corporate assets and also allege that the individual defendants violated their fiduciary duties. Each plaintiff seeks to recover, on behalf of Southern Company, unspecified actual damages and, on each plaintiff's own behalf, attorneys' fees and costs in bringing the lawsuit. Each plaintiff also seeks certain changes to Southern Company's corporate governance and internal processes. In 2018, the court entered an order staying this lawsuit until 30 days after the resolution of any dispositive motions or any settlement, whichever is earlier, in the securities class action.

In May 2017, Helen E. Piper Survivor's Trust filed a shareholder derivative lawsuit in the Superior Court of Gwinnett County, Georgia that names as defendants Southern Company, certain of its directors, certain of its current and former officers, and certain former Mississippi Power officers. The complaint alleges that the individual defendants, among other things, breached their fiduciary duties in connection with schedule delays and cost overruns associated with the construction of the Kemper County energy facility. The complaint further alleges that the individual defendants authorized or failed to correct false and misleading statements regarding the Kemper County energy facility schedule and cost and failed to implement necessary internal controls to prevent harm to Southern Company. The plaintiff seeks to recover, on behalf of Southern Company, unspecified actual damages and disgorgement of profits and, on its behalf, attorneys' fees and costs in bringing the lawsuit. The plaintiff also seeks certain unspecified changes to Southern Company's corporate governance and internal processes. In 2018, the court entered an order staying this lawsuit until 30 days after the resolution of any dispositive motions or any settlement, whichever is earlier, in the securities class action. In August 2019, the court granted a motion filed by the plaintiff in July 2019 to substitute a new named plaintiff, Martin J. Kobuck, in place of Helen E. Piper Survivor's Trust.

Georgia Power

In 2011, plaintiffs filed a putative class action against Georgia Power in the Superior Court of Fulton County, Georgia alleging that Georgia Power's collection in rates of amounts for municipal franchise fees (which fees are paid to municipalities) exceeded the amounts allowed in orders of the Georgia PSC and alleging certain state law claims. This case has been ruled upon and appealed numerous times over the last several years. In one recent appeal, the Georgia Supreme Court remanded the case and noted that the trial court could refer the matter to the Georgia PSC to interpret its tariffs. Following a motion by Georgia Power, in February 2019, the Superior Court of Fulton County ordered the parties to submit petitions to the Georgia PSC for a declaratory ruling and also conditionally certified the proposed class. In March 2019, Georgia Power and the plaintiffs filed petitions with the Georgia PSC seeking confirmation of the proper application of the municipal franchise fee schedule pursuant to the Georgia PSC's orders. Also in March 2019, Georgia Power appealed the class certification decision to the Georgia Court of Appeals. In October 2019, the Georgia PSC issued an order that found Georgia Power has appropriately implemented the municipal franchise fee schedule. On March 11, 2020, the Georgia Court of Appeals vacated the Superior Court of Fulton County's February 2019 order granting conditional class certification. The Court of Appeals remanded the case to the Superior Court of Fulton County for further proceedings. The amount of any possible losses cannot be calculated at this time because, among other factors, it is unknown whether a class will be certified, the ultimate composition of any class, and whether any losses would be subject to recovery from any municipalities.

On July 29, 2020, a group of individual plaintiffs filed a complaint in the Superior Court of Fulton County, Georgia against Georgia Power alleging that releases from Plant Scherer have impacted groundwater, surface water, and air, resulting in alleged personal injuries and property damage. The plaintiffs seek an unspecified amount of monetary damages including punitive damages, a medical monitoring fund, and injunctive relief.

Mississippi Power

In May 2018, Southern Company and Mississippi Power received a notice of dispute and arbitration demand filed by Martin Product Sales, LLC (Martin) based on two agreements, both related to Kemper IGCC byproducts for which Mississippi Power provided termination notices in 2017. Martin alleges breach of contract, breach of good faith and fair dealing, fraud and misrepresentation, and civil conspiracy and makes a claim for damages in the amount of approximately $143 million, as well as additional unspecified damages, attorney's fees, costs, and interest. A portion of the claim for damages was on behalf of Martin Transport, Inc. (Martin Transport), an affiliate of Martin. In May 2019, the arbitration panel denied Mississippi Power's and Southern Company's motions to dismiss. In September 2019, Martin Transport filed a separate complaint against Mississippi Power in the Circuit Court of Kemper County, Mississippi alleging claims of fraud, negligent misrepresentation, promissory estoppel, and equitable estoppel, each arising out of the same alleged facts and circumstances that underlie Martin's arbitration demand. Martin Transport seeks compensatory damages of $5 million and punitive damages of $50 million. In November 2019, Martin Transport's claim was combined with the Martin arbitration case and the

160


Table of Contents                                Index to Financial Statements

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

separate court case was dismissed. In December 2019, Southern Company and Mississippi Power each filed motions for summary judgment on all claims. On February 17, 2020, the arbitration panel granted Southern Company's motion and dismissed Southern Company from the arbitration. On March 12, 2020, the arbitration panel denied Mississippi Power's motions for summary judgment. An adverse outcome in this proceeding could have a material impact on Southern Company's and Mississippi Power's financial statements.

In November 2018, Ray C. Turnage and 10 other individual plaintiffs filed a putative class action complaint against Mississippi Power and the three then-serving members of the Mississippi PSC in the U.S. District Court for the Southern District of Mississippi. Mississippi Power received Mississippi PSC approval in 2013 to charge a mirror CWIP rate premised upon including in its rate base pre-construction and construction costs for the Kemper IGCC prior to placing the Kemper IGCC into service. The Mississippi Supreme Court reversed that approval and ordered Mississippi Power to refund the amounts paid by customers under the previously-approved mirror CWIP rate. The plaintiffs allege that the initial approval process, and the amount approved, were improper. They also allege that Mississippi Power underpaid customers by up to $23.5 million in the refund process by applying an incorrect interest rate. The plaintiffs seek to recover, on behalf of themselves and their putative class, actual damages, punitive damages, pre-judgment interest, post-judgment interest, attorney's fees, and costs. In response to Mississippi Power and the Mississippi PSC each filing a motion to dismiss, the plaintiffs filed an amended complaint in March 2019. The amended complaint included four additional plaintiffs and additional claims for gross negligence, reckless conduct, and intentional wrongdoing. Mississippi Power and the Mississippi PSC have each filed a motion to dismiss the amended complaint. On March 27, 2020, the Mississippi PSC's motion to dismiss was granted. Also on March 27, 2020, the plaintiffs filed a motion seeking to name the new members of the Mississippi PSC, the Mississippi Development Authority, and Southern Company as additional defendants and add a cause of action against all defendants based on a dormant commerce clause theory under the U.S. Constitution. On April 9, 2020 and April 10, 2020, Mississippi Power and the Mississippi PSC, respectively, filed responses opposing the motion for leave to file a second amended complaint. On May 26, 2020, Mississippi Power's motion to dismiss the first amended complaint filed in 2019 was granted. On July 6, 2020, the plaintiffs filed a motion for revision of the court's decision. The plaintiffs' motion for leave to file a second amended complaint also remains pending before the court. An adverse outcome in this proceeding could have a material impact on Mississippi Power's financial statements.

See Note 2 to the financial statements under "Mississippi Power – Kemper County Energy Facility" in Item 8 of the Form 10-K for additional information.

Other Matters

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Other Matters" in Item 7 of the Form 10-K for additional information.

Southern Company

See Notes 1 and 3 under "Leveraged Leases" and "Other Matters – Southern Company," respectively, in Item 8 of the Form 10-K for discussion of challenges associated with a leveraged lease agreement with a subsidiary of Southern Holdings. While all required lease payments through June 30, 2020 have been paid in full, the operational and remarketing risks and the resulting cash liquidity challenges persist and significant concerns continue regarding the lessee's ability to make the remaining required semi-annual lease payments to the Southern Holdings subsidiary through the term of the lease.

In its annual impairment analysis of the expected residual value of the generation assets and the overall collectability of the related lease receivable, Southern Company uses multiple scenarios of long-term market energy prices to estimate the cash flows expected to be received from remarketing the generation assets following the expiration of the existing PPA in 2032 and the residual value of the generation assets at the end of the lease in 2047. Southern Company received the latest annual forecasts of natural gas prices during the second quarter 2020 and considered the significant decline in forecasted prices to be an indicator of potential impairment that required an interim impairment assessment. Accordingly, consistent with prior years, Southern Company evaluated the

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

recoverability of the lease receivable and the expected residual value of the generation assets under various natural gas price scenarios. Based on the current forecasts of energy prices in the years following the expiration of the existing PPA, Southern Company concluded that it is no longer probable that any of the associated rental payments will be received, because it is no longer probable the generation assets will be successfully remarketed and continue to operate after that date. During the second quarter 2020, Southern Company revised the estimated cash flows to be received under the leveraged lease to reflect this conclusion, which resulted in a full impairment of the lease investment and a pre-tax charge to earnings of $154 million ($74 million after tax).

If any future lease payment due prior to the expiration of the associated PPA is not paid in full, the Southern Holdings subsidiary may be unable to make its corresponding payment to the holders of the underlying non-recourse debt related to the generation assets. Failure to make the required payment to the debtholders could represent an event of default that would give the debtholders the right to foreclose on, and take ownership of, the generation assets, in effect terminating the lease. As the full amount of the lease investment has been charged against earnings as of June 30, 2020, termination would not be expected to result in additional charges. Southern Company will continue to monitor the operational performance of the underlying assets and evaluate the ability of the lessee to continue to make the required lease payments and meet its obligations associated with a future closure or retirement of the generation assets and associated properties, including the dry ash landfill.

Mississippi Power

Kemper County Energy Facility

See Note 2 to the financial statements under "Mississippi Power – Kemper County Energy Facility" in Item 8 of the Form 10-K for additional information.

As the mining permit holder, Liberty Fuels Company, LLC has a legal obligation to perform mine reclamation and Mississippi Power has a contractual obligation to fund all reclamation activities related to the lignite mine and equipment and mineral reserves located around the Kemper County energy facility site. As a result of the abandonment of the Kemper IGCC, final mine reclamation began in 2018 and is expected to be substantially completed in 2020, with monitoring expected to continue through 2027. See Note 6 to the financial statements in Item 8 of the Form 10-K for additional information.

Dismantlement of the abandoned gasifier-related assets and site restoration activities are expected to be completed in 2025. The additional pre-tax period costs associated with dismantlement and site restoration activities, including related costs for compliance and safety, ARO accretion, and property taxes, are estimated to total $5 million for the remainder of 2020, $16 million in 2021, and $11 million to $13 million annually in 2022 through 2025. In addition, closure costs for the mine and gasifier-related assets, currently estimated at up to $6 million pre-tax (excluding dismantlement costs, net of salvage), may be incurred during the remainder of 2020.

In December 2019, Mississippi Power transferred ownership of the CO2 pipeline to an unrelated gas pipeline company, with no resulting impact on income. In conjunction with the transfer of the CO2 pipeline, the parties agreed to enter into a 15-year firm transportation agreement, which is expected to be signed by the end of 2020, providing for the conversion by the pipeline company of the CO2 pipeline to a natural gas pipeline to be used for the delivery of natural gas to Plant Ratcliffe. The agreement will be treated as a finance lease for accounting purposes upon commencement.

In 2018, Mississippi Power filed with the DOE its request for property closeout certification under the contract related to the $387 million of grants received for the Kemper County energy facility. Mississippi Power expects to close out the DOE contract in 2020. In connection with the DOE closeout discussions, in April 2019, the Civil Division of the Department of Justice informed Southern Company and Mississippi Power of an investigation related to the Kemper County energy facility. The ultimate outcome of this matter cannot be determined at this time; however, it could have a material impact on Southern Company's and Mississippi Power's financial statements.

Plant Daniel

In conjunction with Southern Company's sale of Gulf Power, Mississippi Power and Gulf Power agreed to seek a restructuring of their 50% undivided ownership interests in Plant Daniel such that each of them would, after the restructuring, own 100% of a generating unit. On April 24, 2020, Mississippi Power and Gulf Power amended the terms of the agreement to extend the deadline from May 1, 2020 to August 1, 2020 for Mississippi Power to notify Gulf Power of which generating unit it has selected for 100% ownership. Mississippi Power and Gulf Power are continuing negotiations on a mutually acceptable revised operating agreement for Plant Daniel and, as a result, the parties have agreed not to select a specific unit on August 1, 2020. The impacts of operating the units on an individual basis continue to be evaluated by Mississippi Power and any transfer of ownership would be subject to approval by the FERC and the Mississippi PSC. The ultimate outcome of this matter cannot be determined at this time.

ACCOUNTING POLICIES

Application of Critical Accounting Policies and Estimates

The Registrants prepare their financial statements in accordance with GAAP. Significant accounting policies are described in the notes to the financial statements in Item 8 of the Form 10-K. In the application of these policies, certain estimates are made that may have a material impact on the Registrants' results of operations and related disclosures. Different assumptions and measurements could produce estimates that are significantly different from those recorded in the financial statements. See MANAGEMENT'S DISCUSSION AND ANALYSIS – ACCOUNTING POLICIES – "Application of Critical Accounting Policies and Estimates" in Item 7 of the Form 10-K for a complete discussion of the Registrants' critical accounting policies and estimates.

Estimated Cost, Schedule, and Rate Recovery for the Construction of Plant Vogtle Units 3 and 4

(Southern Company and Georgia Power)

In the second quarter 2018, Georgia Power revised its base capital cost forecast and contingency to complete construction and start-up of Plant Vogtle Units 3 and 4 to $8.0 billion and $0.4 billion, respectively, for a total project capital cost forecast of $8.4 billion (net of $1.7 billion received under the Guarantee Settlement Agreement and approximately $188 million in related customer refunds). Through the second quarter 2020, assignment of construction contingency to the base capital cost forecast exceeded the amount originally established in the second quarter 2018 by approximately $34 million. As a result, Southern Nuclear recommended establishing additional construction contingency, of which Georgia Power's share is $115 million.

After considering the significant level of uncertainty that exists regarding the future recoverability of these costs since the ultimate outcome of these matters is subject to the outcome of future assessments by management, as well as Georgia PSC decisions in these future regulatory proceedings, Georgia Power recorded a total pre-tax charge to income of $1.1 billion ($0.8 billion after tax) in the second quarter 2018 and a total pre-tax charge to income of $149 million ($111 million after tax) in the second quarter 2020.

In July 2020, Southern Nuclear updated its aggressive site work plan for both Unit 3 and Unit 4. To meet the targets in the July 2020 aggressive site work plan, absenteeism rates must continue to normalize and overall construction productivity and production levels, including subcontractors, must significantly improve and be sustained above pre-pandemic levels. In addition, appropriate levels of craft laborers, particularly electrical and pipefitter craft labor, must be added and maintained. While Southern Nuclear's July 2020 aggressive site work plan extended milestone dates from the February 2020 aggressive site work plan, Georgia Power still expects to achieve the regulatory-approved in-service dates of November 2021 and November 2022 for Plant Vogtle Units 3 and 4, respectively. The continuing effects of the COVID-19 pandemic and other factors could further disrupt or delay construction, testing, supervisory, and support activities at Plant Vogtle Units 3 and 4.

The ultimate impact of these matters on the construction schedule and budget for Plant Vogtle Units 3 and 4 cannot be determined at this time. See Note (B) to the Condensed Financial Statements under "Nuclear Construction" herein for additional information.

Recently Issued Accounting Standards

On March 12, 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASU 2020-04) providing temporary guidance to ease the potential burden in accounting for reference rate reform primarily resulting from the discontinuation of LIBOR, which is currently expected to occur on December 31, 2021. The amendments in ASU 2020-04 are elective and apply to all entities that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The new guidance provides the following optional expedients: (i) simplifies accounting analyses under current GAAP for contract modifications; (ii) simplifies the assessment of hedge effectiveness and allows hedging relationships affected by reference rate reform to continue; and (iii) allows a one-time election to sell or transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform. An entity may elect to apply the amendments prospectively from March 12, 2020 through December 31, 2022 by accounting topic.

The Registrants currently reference LIBOR for certain debt and hedging arrangements. Contract language has been, or is expected to be, incorporated into each of these agreements to address the transition to an alternative rate for agreements that will be in place at the transition date. While existing effective hedging relationships are expected to continue, the Registrants are continuing to evaluate the provisions of ASU 2020–04 and the impacts of transitioning to an alternative rate. The ultimate outcome of the transition cannot be determined at this time, but is not expected to have a material impact on the Registrants' financial statements. See FINANCIAL CONDITION AND LIQUIDITY – "Financing Activities" herein and Note (J) to the Condensed Financial Statements under "Interest Rate Derivatives" herein for additional information.

FINANCIAL CONDITION AND LIQUIDITY

Overview

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Overview" in Item 7 of the Form 10-K for additional information. The financial condition of each Registrant remained stable at June 30, 2020. The Registrants have maintained adequate access to capital throughout 2020, including during periods of volatility in the financial markets. This volatility began to constrain access across the Southern Company system to commercial paper during certain periods. As a precautionary measure, in the first quarter 2020, Southern Company, Georgia Power, Mississippi Power, and Southern Company Gas increased their outstanding short-term debt while also increasing cash and cash equivalents by taking actions such as entering into new bank term loans, entering into and funding new committed and uncommitted credit facilities, funding existing uncommitted credit facilities, and issuing commercial paper with longer-date maturities when available. No material changes occurred in the terms of the applicable Registrants' bank credit arrangements or their interest expense on short-term debt as a result of these actions.

The Registrants have experienced no material counterparty credit losses as a result of the volatility in the financial markets. The Registrants intend to continue to monitor their access to short-term and long-term capital markets as well as their bank credit arrangements to meet future capital and liquidity needs. The impact on future financing costs as a result of continued financial market volatility cannot be determined at this time. See "Capital Requirements and Contractual Obligations," "Sources of Capital," and "Financing Activities" herein and Note (K) to the Condensed Financial Statements herein for additional information.

At the end of the second quarter 2020, the market price of Southern Company's common stock was $51.85 per share (based on the closing price as reported on the NYSE) and the book value was $26.20 per share, representing a market-to-book ratio of 198%, compared to $63.70, $26.11, and 244%, respectively, at the end of 2019. Southern Company's common stock dividend for the second quarter 2020 was $0.64 per share compared to $0.62 per share in the second quarter 2019.

Capital Requirements and Contractual Obligations

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Capital Requirements" and "Contractual Obligations" in Item 7 of the Form 10-K for a description of the Registrants' capital requirements and contractual obligations. The following table provides the applicable Registrants' maturities of long-term debt through June 30, 2021:

At June 30, 2020: Southern Company Alabama Power Georgia<br>Power Southern Power Southern Company Gas
(in millions)
Securities due within one year $ 1,596 $ 496 $ 536 $ 525 $ 31

See "Sources of Capital" and "Financing Activities" herein for additional information.

The construction programs are subject to periodic review and revision, and actual construction costs may vary from these estimates because of numerous factors. These factors include: changes in business conditions; changes in load projections; changes in environmental laws and regulations; the outcome of any legal challenges to environmental rules; changes in electric generating plants, including unit retirements and replacements and adding or changing fuel sources at existing electric generating units, to meet regulatory requirements; changes in FERC rules and regulations; state regulatory agency approvals; changes in the expected environmental compliance program; changes in legislation; the cost and efficiency of construction labor, equipment, and materials; project scope and design changes; abnormal weather; delays in construction due to judicial or regulatory action; storm impacts; and the cost of capital. The continued COVID-19 pandemic could also impair the ability to develop, construct, and operate facilities, as discussed further in Item 1A herein. In addition, there can be no assurance that costs related to capital expenditures will be fully recovered. Additionally, Southern Power's planned expenditures for plant acquisitions may vary due to market opportunities and Southern Power's ability to execute its growth strategy. See Note 15 to the financial statements under "Southern Power" in Item 8 of the Form 10-K and Note (K) to the Condensed Financial Statements under "Southern Power" herein for additional information regarding Southern Power's plant acquisitions and construction projects.

The construction program of Georgia Power also includes Plant Vogtle Units 3 and 4, which includes components based on new technology that only within the last few years began initial operation in the global nuclear industry at this scale and which may be subject to additional revised cost estimates during construction. See Note 2 to the financial statements under "Georgia Power – Nuclear Construction" in Item 8 of the Form 10-K, Note (B) to the

Condensed Financial Statements under "Georgia Power – Nuclear Construction" herein, and Item 1A herein for information regarding Plant Vogtle Units 3 and 4 and additional factors that may impact construction expenditures.

As a result of the second quarter 2020 increase in Alabama Power's AROs discussed under FUTURE EARNINGS POTENTIAL – "Environmental Matters" herein, Alabama Power's costs through 2024 associated with closure and monitoring of ash ponds and landfills in accordance with the CCR Rule and the related state rule are currently estimated to be approximately $263 million for 2020, $247 million for 2021, $301 million for 2022, $330 million for 2023, and $326 million for 2024. These costs are reflected in Alabama Power's ARO liabilities and are based on closure-in-place for all of its ash ponds. These anticipated costs are likely to change, and could change materially, as assumptions and details pertaining to closure are refined and compliance activities continue. See FUTURE EARNINGS POTENTIAL – "Environmental Matters – Environmental Laws and Regulations – Coal Combustion Residuals" in Item 8 of the Form 10-K and Note (A) to the Condensed Financial Statements herein for additional information.

Sources of Capital

Southern Company intends to meet its future capital needs through operating cash flows, borrowings from financial institutions, and debt and equity issuances in the capital markets. Equity capital can be provided from any combination of Southern Company's stock plans, private placements, or public offerings. Southern Company does not expect to issue any equity in the capital markets through 2024.

The Subsidiary Registrants plan to obtain the funds to meet their future capital needs from sources similar to those they used in the past, which were primarily from operating cash flows, external securities issuances, borrowings from financial institutions, and equity contributions from Southern Company. In addition, Georgia Power plans to utilize borrowings from the FFB (as discussed further in Note 8 to the financial statements under "Long-term Debt – DOE Loan Guarantee Borrowings" in Item 8 of the Form 10-K) and Southern Power plans to utilize tax equity partnership contributions (as discussed further herein).

The traditional electric operating companies and the natural gas distribution utilities have experienced a reduction in operating cash flows as a result of the temporary suspension of disconnections for non-payment by customers resulting from the COVID-19 pandemic and the related overall economic contraction. The U.S. House of Representatives has passed the Heroes Act, which would prohibit creditors, including utilities, from collecting consumer debts that are or become past-due, imposing late fees, or disconnecting customers for nonpayment. If the Heroes Act becomes law, its restrictions would apply until 120 days after the end of the presidential declared emergency related to the COVID-19 pandemic. While the reduction in operating cash flows is expected to continue while disconnections for non-payment are suspended, the ultimate extent of the negative impact on the Registrants' liquidity depends on the duration of the COVID-19 pandemic and the timing of economic recovery and cannot be determined at this time. The Registrants intend to continue to monitor their access to short-term and long-term capital markets as well as their bank credit arrangements to meet future capital and liquidity needs. See Note (B) to the Condensed Financial Statements herein for information regarding suspended disconnections for non-payment by the traditional electric operating companies and the natural gas distribution utilities.

The amount, type, and timing of any financings in 2020, as well as in subsequent years, will be contingent on investment opportunities and the Registrants' capital requirements and will depend upon prevailing market conditions, regulatory approvals (for the Subsidiary Registrants), and other factors. See "Capital Requirements and Contractual Obligations" herein for additional information. Also see "Overview" herein for information on volatility in the financial markets that has occurred at certain periods during 2020 as a result of the COVID-19 pandemic.

Southern Power utilizes tax equity partnerships as one of its financing sources, where the tax partner takes significantly all of the federal tax benefits. These tax equity partnerships are consolidated in Southern Power's financial statements and are accounted for using HLBV methodology to allocate partnership gains and losses. In June 2020, Southern Power obtained tax equity funding for the Reading wind project and received proceeds of $156 million. In addition, during the first six months of 2020, Southern Power received tax equity funding totaling $16

million from existing partnerships. See Note 1 to the financial statements under "General" in Item 8 of the Form 10-K and Note (K) to the Condensed Financial Statements under "Southern Power" herein for additional information.

By regulation, Nicor Gas is restricted, to the extent of its retained earnings balance, in the amount it can dividend or loan to affiliates and is not permitted to make money pool loans to affiliates. At June 30, 2020, the amount of subsidiary retained earnings restricted to dividend totaled $1.1 billion. This restriction did not impact Southern Company Gas' ability to meet its cash obligations, nor does management expect such restriction to materially impact Southern Company Gas' ability to meet its currently anticipated cash obligations.

See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Sources of Capital" in Item 7 of the Form 10-K for additional information.

The Registrants' current liabilities frequently exceed their current assets because of long-term debt maturities and the periodic use of short-term debt as a funding source, as well as significant seasonal fluctuations in cash needs. The following table shows the amount by which current liabilities exceeded current assets at June 30, 2020 for the applicable Registrants:

At June 30, 2020 Southern Company Georgia<br>Power Mississippi Power Southern Company Gas
(in millions)
Current liabilities in excess of current assets $ 265 $ 1,132 $ 70 $ 209

The Registrants believe the need for working capital can be adequately met by utilizing operating cash flows, as well as commercial paper, lines of credit, and short-term bank notes, as market conditions permit. In addition, under certain circumstances, the Subsidiary Registrants may utilize equity contributions and/or loans from Southern Company.

Bank Credit Arrangements

At June 30, 2020, the Registrants' unused committed credit arrangements with banks were as follows:

(a) At June 30, 2020, Southern Power also had two continuing letters of credit facilities for standby letters of credit, of which $79 million was unused. Southern Power's subsidiaries are not parties to its bank credit arrangement or to the letter of credit facilities.
--- ---
(b) Includes $1.245 billion and $500 million at Southern Company Gas Capital and Nicor Gas, respectively.

Subject to applicable market conditions, the Registrants, Nicor Gas, and SEGCO expect to renew or replace their bank credit arrangements as needed, prior to expiration. In connection therewith, the Registrants, Nicor Gas, and SEGCO may extend the maturity dates and/or increase or decrease the lending commitments thereunder.

A portion of the unused credit with banks is allocated to provide liquidity support to the revenue bonds of the traditional electric operating companies and the commercial paper programs of the Registrants, Nicor Gas, and SEGCO. The amount of variable rate revenue bonds of the traditional electric operating companies outstanding requiring liquidity support at June 30, 2020 was approximately $1.4 billion (comprised of approximately $854 million at Alabama Power, $550 million at Georgia Power, and $34 million at Mississippi Power). In addition, at June 30, 2020, Georgia Power had approximately $257 million of fixed rate revenue bonds outstanding that are required to be remarketed within the next 12 months.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS (Continued)

There are certain contracts that could require collateral, but not accelerated payment, in the event of a credit rating change of certain subsidiaries to BBB and/or Baa2 or below. These contracts are for physical electricity and natural gas purchases and sales, fuel purchases, fuel transportation and storage, energy price risk management, transmission, interest rate management, and, for Georgia Power, construction of new generation at Plant Vogtle Units 3 and 4.

The maximum potential collateral requirements under these contracts at June 30, 2020 were as follows:

Credit Ratings Southern Company^(*)^ Alabama Power Georgia Power Mississippi Power Southern<br><br>Power^(*)^ Southern Company Gas
(in millions)
At BBB and/or Baa2 $ 36 $ 1 $ $ $ 35 $
At BBB- and/or Baa3 428 2 61 1 366
At BB+ and/or Ba1 or below 1,926 319 899 265 1,188 7
(*) Southern Power has PPAs that could require collateral, but not accelerated payment, in the event of a downgrade of Southern Power's credit. The PPAs require credit assurances without stating a specific credit rating. The amount of collateral required would depend upon actual losses resulting from a credit downgrade. Southern Power had $105 million of cash collateral posted related to PPA requirements at June 30, 2020.
--- ---

The potential collateral requirement amounts in the previous table for the traditional electric operating companies and Southern Power include certain agreements that could require collateral in the event that either Alabama Power or Georgia Power has a credit rating change to below investment grade. Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash. Additionally, a credit rating downgrade could impact the ability of the Registrants to access capital markets and would be likely to impact the cost at which they do so.

Market Price Risk

Other than the Southern Company Gas items discussed below, there were no material changes to the Registrants' disclosures about market price risk during the second quarter 2020. For an in-depth discussion of Southern Company Gas' market price risks, see MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Market Price Risk" in Item 7 of the Form 10-K. Also see "Overview" herein for information on volatility in the financial markets that has occurred at certain periods during 2020 resulting from the COVID-19 pandemic and Notes (I) and (J) to the Condensed Financial Statements herein for information relating to derivative instruments.

Southern Company Gas is exposed to market risks, including commodity price risk, interest rate risk, and weather risk. Due to various cost recovery mechanisms, the natural gas distribution utilities that sell natural gas directly to end-use customers continue to have limited exposure to market volatility of natural gas prices. Certain of the natural gas distribution utilities may manage fuel-hedging programs implemented per the guidelines of their respective state regulatory agencies to hedge the impact of market fluctuations in natural gas prices for customers. In addition, certain non-regulated operations routinely utilize various types of derivative instruments to economically hedge certain commodity price and weather risks inherent in the natural gas industry. These instruments include a variety of exchange-traded and over-the-counter energy contracts, such as forward contracts, futures contracts, options contracts, and swap agreements. Some of these economic hedge activities may not qualify, or may not be designated, for hedge accounting treatment.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

During the six months ended June 30, 2020, there were no material changes to Southern Company's, Alabama Power's, Georgia Power's, Mississippi Power's, and Southern Power's disclosures about market risk. For additional market risk disclosures relating to Southern Company Gas, see MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Market Price Risk" herein. For an in-depth discussion of each Registrant's market risks, see MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Market Price Risk" in Item 7 of the Form 10-K and Note 1 to the financial statements under "Financial Instruments" and Notes 13 and 14 to the financial statements in Item 8 of the Form 10-K, as well as Notes (I) and (J) to the Condensed Financial Statements herein.

Item 4. Controls and Procedures.

(a) Evaluation of disclosure controls and procedures.

As of the end of the period covered by this Quarterly Report on Form 10-Q, Southern Company, Alabama Power, Georgia Power, Mississippi Power, Southern Power, and Southern Company Gas conducted separate evaluations under the supervision and with the participation of each company's management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures (as defined in Sections 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended). Based upon these evaluations, the Chief Executive Officer and the Chief Financial Officer, in each case, concluded that the disclosure controls and procedures are effective.

(b) Changes in internal controls over financial reporting.

There have been no changes in Southern Company's, Alabama Power's, Georgia Power's, Mississippi Power's, Southern Power's, or Southern Company Gas' internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended) during the second quarter 2020 that have materially affected or are reasonably likely to materially affect Southern Company's, Alabama Power's, Georgia Power's, Mississippi Power's, Southern Power's, or Southern Company Gas' internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings.

See the Notes to the Condensed Financial Statements herein for information regarding certain legal and administrative proceedings in which the Registrants are involved.

Item 1A. Risk Factors.

See RISK FACTORS in Item 1A of the Form 10-K for a discussion of the risk factors of the Registrants. Except as described below, there have been no material changes to these risk factors from those previously disclosed in the Form 10-K.

The Registrants are subject to risks related to the COVID-19 pandemic, including, but not limited to, disruption to the construction of Plant Vogtle Units 3 and 4 for Southern Company and Georgia Power.

COVID-19 has been declared a pandemic by the World Health Organization and the Centers for Disease Control and Prevention and has spread globally, including throughout the United States. In response, most jurisdictions, including in the United States, have instituted restrictions on travel, public gatherings, and non-essential business operations. While some jurisdictions, including some in the Southern Company system's service territory, have begun to relax these restrictions, many of these restrictions remain and there is no guarantee restrictions will not be reimposed in the future. These restrictions have significantly disrupted economic activity in the service territories of the traditional electric operating companies and the natural gas distribution utilities and caused volatility in capital markets at certain periods during 2020. For example, retail electric revenues attributable to changes in sales decreased 3.0% in the second quarter 2020 as compared to the corresponding period in 2019, as discussed further in RESULTS OF OPERATIONS – "Southern Company – Retail Electric Revenues" in Item 2 herein. In addition, the traditional electric operating companies and the natural gas distribution utilities temporarily suspended disconnections for non-payment by customers and waived late fees for certain periods. The U.S. House of Representatives has passed the Heroes Act, which would prohibit creditors, including utilities, from collecting consumer debts that are or become past-due, imposing late fees, or disconnecting customers for nonpayment. If the Heroes Act becomes law, its restrictions would apply until 120 days after the end of the presidential declared emergency related to the COVID-19 pandemic. The effects of the continued COVID-19 pandemic and related responses could include extended disruptions to supply chains and capital markets, further reduced labor availability and productivity, and a prolonged reduction in economic activity. These effects could have a variety of adverse impacts on the Registrants, including continued reduced demand for energy, particularly from commercial and industrial customers, reduced cash flows and liquidity, impairment of goodwill or long-lived assets, reductions in investments recorded at fair value, and further impairment of the ability of the Registrants to develop, construct, and operate facilities, including electric generation, transmission, and distribution assets, to perform necessary corporate and customer service functions, and to access funds from financial institutions and capital markets. In addition, the COVID-19 pandemic could cause delays or cancellations to regulatory proceedings.

Further, the effects of the COVID-19 pandemic could further disrupt or delay construction, testing, supervisory, and support activities at Plant Vogtle Units 3 and 4. In mid-March 2020, Southern Nuclear began implementing policies and procedures designed to mitigate the risk of transmission of COVID-19 at the construction site, including worker distancing measures, isolating individuals who have tested positive for COVID-19, are showing symptoms consistent with COVID-19, are being tested for COVID-19, or have been in close contact with such persons, requiring self-quarantine, and adopting additional precautionary measures. In April 2020, Georgia Power announced a reduction in workforce at Plant Vogtle Units 3 and 4, which totaled approximately 20% of the then-existing workforce. This reduction in workforce was a mitigation action intended to address the impact of the COVID-19 pandemic on the Plant Vogtle Units 3 and 4 workforce and construction site, including challenges with labor productivity that were exacerbated by the impact of the COVID-19 pandemic. The April 2020 workforce reduction was intended to provide operational efficiencies by increasing productivity of the remaining workforce and reducing workforce fatigue and absenteeism. Further, it was also intended to allow for increased social distancing by the workforce and facilitate compliance with the recommendations from the Centers for Disease Control and Prevention. The April 2020 workforce reduction did reduce absenteeism, providing an improvement in operational efficiency and allowing for increased social distancing. From the initial peak in April 2020, the number of active

178


Table of Contents

cases at the site declined significantly during May and early June, but began increasing again in mid-June and continues to impact productivity levels and pace of activity completion. As a result of these factors, overall production improvements have not been achieved at the levels anticipated, contributing to the allocation of, and increase in, construction contingency described in Note (B) to the Condensed Financial Statements under "Georgia Power – Nuclear Construction" herein. Georgia Power's proportionate share of the estimated incremental cost associated with COVID-19 mitigation actions and impacts on construction productivity is currently estimated to be between $70 million and $115 million, which is included in the total project capital cost forecast and assumes (i) absenteeism rates continue to normalize and (ii) the intended productivity efficiencies and production targets assumed in Southern Nuclear's July 2020 aggressive site work plan are realized in the coming months. However, the ultimate impact of the COVID-19 pandemic on the construction schedule and budget for Plant Vogtle Units 3 and 4 cannot be determined at this time.

MISSISSIPPI POWER COMPANY

BYLAWS

ARTICLE I

Shareholders

SECTION 1.01. Place and Time of Meeting.

All meetings of the shareholders of the Corporation shall be held at such time and place, either within or without the State of Mississippi, as the Chairman of the Board, the President or the Board (as defined in Section 2.01) may determine and as so designated in the call for or notice of the meeting. [79‑4‑7.01 and 79-4-7.02] Notwithstanding the foregoing, the Board may, in its sole discretion, determine that a meeting of shareholders will not be held at any place, but may instead be held by means of remote communications, subject to such guidelines and procedures as the Board may adopt from time to time. [79‑4‑7.09]

SECTION 1.02. Annual Meetings of Shareholders.

At each annual meeting of shareholders, the shareholders will elect the directors from the nominees for director and will transact such other business as may properly be brought before the meeting. [79-4-7.01] If no in-person annual meeting is held, the shareholders may elect the directors from the nominees for director by written consent as set forth in the Amended and Restated Articles of Incorporation, as amended and/or restated from time to time (the “Articles of Incorporation”).

SECTION 1.03. Special Meetings.

Special meetings of the shareholders may be called at any time by (i) the Chairman of the Board, the President, the Board or the Executive Committee or (ii) shareholders holding one‑tenth of the then outstanding capital stock entitled to vote upon dated written demand for the

1


meeting delivered to the Corporation describing the purpose or purposes for which the special meeting is to be held. [79‑4‑7.02]

SECTION 1.04. Notice of Meetings of Shareholders.

Written notice stating the place, day and hour of the meeting and, in case of a special meeting, the purpose or purposes for which the meeting is called, shall, unless waived, as provided below, be given to each shareholder entitled to vote not less than ten (10) nor more than sixty (60) days before the date of the meeting, either personally or by mail, to such address as appears on the books of the Corporation, unless by statute other or further notice is required, and in this event the required statutory notice shall be given. [79‑4‑7.05] Whenever any notice is required to be given to any shareholder, a waiver thereof in writing signed by the person or persons entitled to such notice, whether before or after the time stated therein, shall be equivalent to the giving of such notice. [79‑4‑7.06]

SECTION 1.05. Fixing Date for Determination of Shareholders of Record.

In order to determine the shareholders entitled to notice of or to vote at any meeting of shareholders or any adjournment thereof, or entitled to receive payment of any dividend, or in order to make a determination of shareholders for any other purpose, the Board may fix, in advance, a record date for any such determination of shareholders, which shall not be more than seventy (70) days prior to the date on which the particular action requiring such determination of shareholders is to be taken.

If no record date is fixed for the determination of shareholders entitled to notice of or to vote at a meeting of shareholders, or shareholders entitled to receive payment of a dividend, the date on which notice of the meeting is mailed or the date on which the resolution of the Board declaring such dividend is adopted shall be the record date for such determination of shareholders. If no record date is fixed for the determination of shareholders entitled to take

2


action without a meeting, and (1) if prior Board action is not required respecting the action to be taken without a meeting, the record date for determining the shareholders entitled to take action without a meeting shall be the first date on which a signed written consent is delivered to the Corporation or (2) if prior Board action is required respecting the action to be taken without a meeting, the record date shall be the close of business on the day the resolution of the Board taking such prior action is adopted.

When a determination of shareholders entitled to vote at any meeting of shareholders has been made as provided in this section, such determination shall apply to any adjournment thereof unless the Board fixes a new record date, which it must do if the meeting is adjourned to a date more than one hundred twenty (120) days after the date fixed for the original meeting. [79‑4‑7.07 & 79-4-7.04(c)]

SECTION 1.06. Quorum.

Subject to the provisions of the Articles of Incorporation, the holders of a majority of the shares issued and outstanding and entitled to vote at the meeting, represented in person or by proxy, shall constitute a quorum for the transaction of any business. [79‑4‑7.25]

SECTION 1.07. Voting Rights of Shareholders.

When a quorum is present, unless otherwise provided in the Articles of Incorporation, the affirmative vote of the majority of the shares represented at the meeting and entitled to vote on the subject matter shall constitute the act of shareholders. Any shareholder entitled to vote may vote in person or by proxy appointed by an instrument in writing subscribed by such shareholder, but no proxy shall be valid after eleven (11) months from the date of its execution, unless the proxy provides for a longer period. The proxy holder need not be a shareholder. All elections shall be had and, subject to the provisions of the Articles of Incorporation, all questions decided

3


by a majority vote of the stock voting at the meeting in person or by proxy and entitled to vote thereat. [79‑4‑7.21, 79‑4‑7.22 & 79-4-7.25]

SECTION 1.08. Voting List ‑ Shareholder Examination.

After fixing a record date for a meeting, the officer having charge of the stock transfer books of the Corporation shall prepare an alphabetical list of the names of all its shareholders who are entitled to notice of a shareholders’ meeting. The list must be arranged by voting group (and within each voting group by class or series of shares) and show the address of and number of shares held by each shareholder. The shareholders’ list must be available for inspection by any shareholder, beginning two (2) business days after notice of the meeting is given for which the list was prepared and continuing through the meeting, at the Corporation’s principal office. A shareholder, or his or her agent or attorney, is entitled on written demand to inspect and, for a proper purpose, to copy the list, during regular hours and at his or her expense, during the period it is available for inspection. The Corporation shall make the list available at the meeting, and any shareholder, or his or her agent or attorney, is entitled to inspect the list at any time during the meeting or any adjournment thereof. The stock transfer records of the Corporation shall be prima facie evidence as to who are the shareholders entitled to examine the shareholders’ list or transfer records or to vote at any meeting of shareholders.

Failure to comply with the requirements of this section shall not affect the validity of any action taken at such meeting. [79‑4‑7.20]

SECTION 1.09. Consent in Lieu of Meeting.

Unless otherwise provided in the Articles of Incorporation, any corporate action required or permitted by the Mississippi Business Corporation Act to be taken at a meeting of the shareholders may be taken without a meeting and without prior notice, if consents in writing setting forth the action so taken are signed by the holders of outstanding shares having not less

4


than the minimum number of votes that would be required to authorize or take the action at a meeting at which all shares entitled to vote on the action were present and voted. The written consent shall bear the date of signature of the shareholder who signs the consent and be delivered to the Corporation for inclusion in the minutes or filing with the corporate records. Notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those shareholders who have not consented in writing not more than ten (10) days after (1) written consents sufficient to take such action have been delivered to the Corporation or (2) such later date that tabulation of consents is completed. [79‑4‑7.04(b), (f)]

ARTICLE II

Directors

SECTION 2.01. Management of Business.

The business and affairs of the Corporation shall be managed by the Corporation’s Board of Directors (the “Board”). [79‑4‑8.01(b)]

SECTION 2.02. Number and Qualification of Directors.

The number of directors shall be not less than three (3) nor more than fifteen (15). Within the limits above specified, the number of directors shall be determined by resolution of the Board or by the shareholders entitled to vote for the election of directors at the annual or any special meeting of the shareholders; provided, however, that no decrease shall have the effect of shortening the term of any incumbent director. [79‑4‑8.03 & 79-4-8.05(c)]

Directors need not be residents of Mississippi or shareholders of the Corporation. [79‑4‑8.02]

No person who is engaged or interested in a competing business, either individually or as an employee, shall serve as a director without the consent of the holders of a majority of the common shares issued and outstanding. [79‑4‑8.31]

5


A person being a full‑time executive employee of the Corporation or its parent company or any affiliated company when first elected a director of the Corporation (hereinafter sometimes referred to as an “employee‑director”) shall not be eligible to serve as a director when he or she ceases to be an executive employee, whether by reason of resignation, retirement or other cause.

No director, other than an employee-director of the Corporation, shall serve for more than a total of twelve (12) years in that capacity. Therefore, the Board will not nominate for re-election any non-employee director if the director shall complete his or her twelfth year of service as a member of the Board on or prior to the date of the annual meeting of shareholders at which the nomination would be presented. Additionally, a person not an employee-director shall not be eligible to serve as a director of the Corporation (1) for a newly elected annual term starting after his or her 70^th^ birthday, (2) after permanent separation from the business or professional organization with which he or she was primarily associated when first elected a director, (3) after any other material change in his or her primary occupation or executive position from that which he or she pursued or held when first elected a director or (4) after moving his or her principal residence outside the service area in which he or she was a resident when first elected a director, whichever event first occurs. In special circumstances, the application to an individual of any provision of this section may be waived by the Board. Any such waiver shall only be effective on a year-to-year basis.

A person not an employee-director must tender a resignation from the Board when a change occurs in the director’s eligibility to serve as a director by reason of the foregoing provisions other than reaching his or her 70th birthday. In such case, the Board has the discretion of accepting the resignation or requesting that the director continue to serve on the Board for the remainder of his or her current term.

6


Any employee‑director who is not eligible to serve as a director by reason of the foregoing provisions shall be eligible to serve as an advisory director until he or she shall have reached his or her 70th birthday, if elected or re‑elected by the Board, upon the recommendation of the Chief Executive Officer of the Corporation. The term of office of each advisory director shall terminate on the earlier of the date when he or she ceases to be eligible for such position or, subject to reappointment, the date of the first meeting of the Board after the annual meeting of shareholders next following his or her appointment. Any person eligible for election as an advisory director must be one whose services as such will be, in the opinion of the Board, of value to the Corporation. An advisory director shall be entitled to notice of, to attend, and to advise but not to vote at meetings of the Board and of any committees thereof to which he or she shall be appointed. An advisory director shall not be counted in determining the existence of a quorum, and for his or her services may be paid, in the discretion of the Board, compensation and reimbursement of expenses on the same basis as if he or she were a director.

SECTION 2.03. Election and Term.

The directors shall be elected at the annual meeting of shareholders, and each director shall be elected to hold office until his or her successor shall be elected and qualified, or until his or her earlier resignation or removal. The Board, as soon as may be convenient after the election of directors in each year, may appoint one of their number Chairman of the Board. [79‑4‑8.03(c) & 79-4-8.05(e)]

SECTION 2.04. Vacancies and Newly Created Directorships.

In case of any vacancies in the Board through death, resignation, disqualification or any other cause, including a vacancy resulting from an increase in the number of directors, the vacancy may be filled (1) by the shareholders; (2) by the Board; or (3) if the directors remaining in office constitute fewer than a quorum of the Board, by the remaining directors by the

7


affirmative vote of a majority of all remaining directors, which shall constitute a quorum for such purpose. The director or directors so chosen shall hold office until the next annual election by shareholders and until their successor or successors shall be elected and qualified. [79‑4‑8.10]

SECTION 2.05. Removal.

At a meeting called expressly for that purpose, any and all of the directors may at any time be removed, with or without cause, by a vote of the holders of a majority of the shares then entitled to vote at an election of directors. [79‑4‑8.08]

SECTION 2.06. Quorum of Directors.

At all meetings of the Board, one‑half of the number of directors then in office or, if there shall be an odd number of directors, then a majority thereof, shall constitute a quorum for the transaction of business. The act of the majority of the directors present at a meeting at which a quorum is present shall be the act of the Board. [79‑4‑8.24]

SECTION 2.07. Annual Meeting.

The newly elected Board shall meet as soon as practicable after the annual meeting of shareholders, within or without the State of Mississippi, and no notice of such meeting shall be necessary. [79‑4‑8.20]

SECTION 2.08. Regular Meetings.

Regular meetings of the Board may be held at such time and place, within or without the State of Mississippi, as shall from time to time be fixed by the Chairman of the Board, the President or the Board, and no notice of such meeting shall be necessary. [79‑4‑8.20 & 79-4-8.22(a)]

SECTION 2.09. Special Meetings.

Special meetings may be called at any time by the Chairman of the Board, the President or the Secretary or by the Board. Special meetings shall be held at such place, within or without

8


the State of Mississippi, as shall be fixed by the person or persons calling the meeting and stated in the notice or waiver of notice of the meeting. [79‑4‑8.20]

Notice of a special meeting shall be given by the Secretary, or such other officer performing his or her duties, to each director at least one (1) day prior to such meeting, either personally or by mail, telephone, fax or email. Attendance of a director at a special meeting shall constitute a waiver of notice of such meeting, except when a director attends a meeting for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called or convened. The business to be transacted at or the purpose of a special meeting of the Board need not be stated in such notice or waiver of notice and any and all business may be transacted at a special meeting of the Board. [79‑4‑8.22 & 79‑4‑8.23]

SECTION 2.10. Action Without a Meeting.

Any corporate action either required or permitted by the Mississippi Business Corporation Act, the Articles of Incorporation or these Bylaws to be taken at a meeting of the Board may be taken without a meeting if a consent in writing, setting forth the action so taken, shall be signed by all of the directors entitled to vote with respect to the subject matter thereof. [79‑4‑8.21]

SECTION 2.11. Compensation.

Directors shall be entitled to a fee for performing duties as directors, provided that no fees or salaries shall be paid to those directors who are officers or employees, other than retired employees, who are on a fixed basis of compensation from the Corporation or any subsidiary or affiliated company and who have duties and responsibilities to such companies other than those arising from the office of director. Directors shall be reimbursed for actual expenses incurred in attending meetings of the Board or any committee thereof and in otherwise performing duties as

9


directors or in lieu thereof to an allowance for expenses. The amount of fee or salary paid to directors and expense allowance, if any, shall be fixed by the Board. [79‑4‑8.11]

SECTION 2.12. Executive and Other Committees.

The Board may, by resolution or resolutions passed by a majority of the directors present at a meeting at which a quorum is present, designate an Executive Committee and one or more other committees, including without limitation Controls and Compliance and Compensation Committees, each consisting of one or more directors (at least one of which shall be a non-employee director), and each of which committees may act by a majority of its members. The Executive Committee shall have and may exercise all the powers and authority of the Board in the management of the business and affairs of the Corporation when the Board is not meeting; and each other committee shall have such powers of the Board and otherwise as are provided in the resolution establishing such committee. Notwithstanding anything to the contrary herein, the Executive Committee and all other committees established by the Board shall have no power or authority to take any action specifically prohibited under the Mississippi Business Corporation Act, Miss. Code Ann. §79‑4‑8.25(e), or any successor statute. Unless otherwise specifically permitted by the Board, the rules promulgated by these Bylaws with respect to meetings of directors, notice, quorums, voting and other procedures at such meetings shall be applicable to meetings of committees established by the Board. [79‑4‑8.25]

SECTION 2.13. Participation in Meeting.

Members of the Board or any committee thereof may participate in any regular or special meeting of the Board or any committee thereof by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, simultaneously, and such participation shall constitute presence in person at the meeting. [79‑4‑8.20]

10


SECTION 2.14. Interest of Director in Corporate Act.

A director of the Corporation shall not be disqualified by his or her office from dealing or contracting with the Corporation, either as vendor, purchaser or otherwise, nor shall any transaction or contract of the Corporation be void or voidable by reason of the fact that any director or any firm of which any director is a member or any corporation of which any director is a shareholder or director is in any way interested in such transaction or contract, provided that such transaction or contract is or shall be authorized, ratified or approved either (1) by vote of a majority or a quorum of the Board or the Executive Committee, without counting in such majority or quorum any directors so interested or being a member of a firm so interested or a shareholder or director of a corporation so interested, or (2) by vote at a shareholders’ meeting of the holders of a majority of all the outstanding shares of the stock of the Corporation entitled to vote or by a writing or writings signed by a majority of such holders; nor shall any director be liable to account to the Corporation for any profit realized by him or her from or through any transaction or contract of the Corporation authorized, ratified or approved as aforesaid, by reason of the fact that he or she or any firm of which he or she is a member or any corporation of which he or she is a shareholder or director was interested in such transaction or contract. Nothing herein contained shall create any liability in the events above described or prevent the authorization, ratification or approval of such contracts or transactions in any other manner provided by law.

ARTICLE III

The Board may from time to time, but shall not be required to, establish the office of Chairman of the Board and may, but shall not be required to, designate the holder of such office, if established, as Chief Executive Officer of the Corporation.

ARTICLE IV

Indemnification of Directors and Officers

SECTION 4.01. Indemnification and Related Matters.

To the fullest extent permitted by law, the Corporation shall indemnify each person made, or threatened to be made, a party to any threatened, pending or completed claim, action, suit or proceeding, whether civil or criminal, administrative or investigative, and whether by or in the right of the Corporation or otherwise, by reason of the fact that such person, or such person’s testator or intestate, is or was a director or officer or was an employee of the Corporation holding one or more management positions through and inclusive of department managers (but not positions below the level of department managers) (such positions being hereinafter referred to as “Management Positions”) or is or was serving at the request of the Corporation as a director, officer, employee, agent or trustee of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, in any capacity at the request of the Corporation, against all loss and expense actually or reasonably incurred by him or her including, without limiting the generality of the foregoing, judgments, fines, penalties, liabilities, sanctions and amounts paid in settlement and attorney’s fees and disbursements actually and

14


necessarily incurred by him or her in defense of such action or proceeding, or any appeal therefrom. The indemnification provided by this Section shall inure to the benefit of the heirs, executors and administrators of such person.

In any case in which a director or officer of the Corporation or employee of the Corporation holding one or more Management Positions requests indemnification with respect to the defense of any such claim, action, suit or proceeding, the Corporation may advance expenses (including attorney’s fees) incurred by such person prior to the final disposition of such claim, action, suit or proceeding, as authorized by the Board in the specific case, upon receipt of (1) a signed written affirmation of such person’s good faith belief that the relevant standard of conduct described in the Mississippi Business Corporation Act has been met by such person and (2) a written undertaking by or on behalf of such person to repay amounts advanced if it shall ultimately be determined that such person was not entitled to be indemnified by the Corporation under this Section or otherwise; provided, however, that the advancement of such expenses shall not be deemed to be indemnification unless and until it shall ultimately be determined that such person is entitled to be indemnified by the Corporation.

Such a person claiming indemnification shall be entitled to indemnification upon a determination that no judgment or other final adjudication adverse to such person has established that such person’s acts were committed in bad faith or were the result of active and deliberate dishonesty and were material to the cause of action so adjudicated, or such person personally obtained an economic benefit including a financial profit or other advantage to which such person was not legally entitled.

The foregoing rights shall not be exclusive of any other rights to which any such director, officer or employee may otherwise be entitled and shall be available whether or not the director,

15


officer or employee continues to be a director, officer or employee at the time of incurring any such expenses and liabilities.

If any word, clause or provision of the Bylaws or any indemnification made under this Section 4.01 shall for any reason be determined to be invalid, the remaining provisions of the Bylaws shall not otherwise be affected thereby but shall remain in full force and effect. [79-4-8.51, 79-4-8.52, 79-4-8.53, 79-4-8.55, 79-4-8.56 & 79-4-8.58]

SECTION 4.02. Liability Insurance.

The Corporation may purchase and maintain insurance on behalf of any person described in Section 4.01 against any liability or expense (including attorney’s fees) which may be asserted against such person whether or not the Corporation would have the power to indemnify such person against such liability or expense under this Article IV or otherwise. [79-4-8.57]

ARTICLE V

The shares of the Corporation shall be represented by a certificate or shall be uncertificated and shall be entered in the books of the Corporation and registered as they are issued. The certificates shall be signed by the President or a Vice President of the Corporation, and by the Secretary or an Assistant Secretary of the Corporation, one of which may be facsimile signature, and may be sealed with the seal of the Corporation or a facsimile thereof. The signatures of the President or Vice President and the Secretary or Assistant Secretary upon a certificate may both be facsimiles if the certificate is countersigned by a transfer agent or registered by a registrar, other than the Corporation itself or an employee of the Corporation. In case any officer who has signed or whose facsimile signature has been placed upon a certificate

16


shall have ceased to be such officer before such certificate is issued, it may be issued by the Corporation with the same effect as if he or she were such officer at the date of issue.

The certificates of stock of the Corporation shall be numbered, shall exhibit the name of the registered holder and shall certify the number of shares owned by him or her. Within a reasonable time after the issue or transfer of shares without certificates, the Corporation shall send the shareholder a written statement of the information required on the certificates pursuant to the Mississippi Business Corporation Act. [79‑4‑6.25]

SECTION 5.02. Registered Holders.

Prior to due presentment for registration of transfer of any security of the Corporation in registered form, the Corporation shall treat the registered owner as the person exclusively entitled to vote, to receive notifications and to otherwise exercise all the rights and powers of an owner, and shall not be bound to recognize any equitable or other claim to, or interest in, any security, whether or not the Corporation shall have notice thereof, except as otherwise provided by the laws of the State of Mississippi.

SECTION 5.03. Transfers.

The stock of the Corporation shall be transferable or assignable on the books of the Corporation by the holders in person or by attorney on the surrender of the certificates therefor duly endorsed or upon receipt of proper transfer instructions from the registered owner of uncertificated shares or in any other manner prescribed by the laws of the State of Mississippi.

SECTION 5.04. Replacement Certificates.

The Corporation may issue a new certificate or uncertificated shares of stock in place of any certificates theretofore issued by it, alleged to have been lost or destroyed, provided the person seeking the issuance of the new certificate or uncertificated shares of stock shall be the owner or satisfy the Corporation he or she is the owner of the stock certificate alleged to have

17


been lost or destroyed, and the Corporation shall require the owner of the lost or destroyed certificate, or his or her legal representatives, to give the Corporation a bond sufficient to indemnify the Corporation against any claim that may be made against it on account of the alleged loss or destruction of any such certificate or the issuance of such new certificate or uncertificated shares of stock. The issuance of a new certificate or uncertificated shares of stock, as herein above provided, shall not relieve the Corporation or the directors from corporate or personal liability in damages to any person to whom the original certificate has been or shall be transferred for value without notice of the issuance of the new certificate or uncertificated shares of stock.

NOW THEREFORE, in consideration of the foregoing, and in further consideration of the mutual covenants and agreements set forth below, the parties, each intending to be legally bound, covenant and agree as follows:

1.    Employment. The Company has employed Employee, and the Company hereby continues to employ Employee and Employee hereby accepts such employment upon the terms and conditions set forth in this Agreement.

2.    Term. The “Term” of employment and this Agreement shall be from the effective date of this Agreement and shall continue until December 31, 2023 or the date Employee’s employment is terminated pursuant to paragraph 5 below, whichever is sooner (the “Termination Date”). As of the Termination Date, Employee will no longer be employed by the Company in any capacity and will be not entitled to any further compensation as an employee of the Company; however, nothing in this Agreement affects Employee’s vested interests in any benefit plans offered by the Company in which Employee has participated.

3.    Duties and Responsibilities While Loaned to EDPA.

(a)    Title and Authority. Beginning on June 8, 2020, Employee will be the President of the EDPA, subject to the election by the EDPA Board of Directors. After June 8, 2020, Employee will not have authority to act for or on behalf of the Company in any capacity other than as provided in paragraph (b) below.

(b)    Duties. The Employee shall be loaned by the Company to perform services for the EDPA and shall perform duties and responsibilities that are customary to the President of the EDPA position, or as may be assigned to him from time to time by the Board of Directors of the EDPA. The Employee shall report to the Chairman, President and CEO of the Company and the EDPA Board of Directors. Employee will be subject to all policies and practices of the Company and the EDPA.

(c)    Potential Continuation of Service to EDPA following Term of Agreement. Following the Termination Date, EDPA and Employee may negotiate a continuation of his role as the President of EDPA on terms that are mutually acceptable by the EDPA and Employee. Any compensation to Employee following the Termination Date will be provided by EDPA.


4.    Compensation and Benefits. For the services rendered by Employee under and during the term of this Agreement, Employee shall continue to receive his current salary, incentive pay, benefits, and any merit increases provided to other employees in his same compensation level to the extent consistent with applicable law and terms of applicable plans; provided, however, that the incentive pay may be adjusted (positively or negatively) based upon Employee’s performance as President of EDPA. The Company reserves the right to amend or cancel any Employee Benefit Plans at any time in its sole discretion, subject to the terms of such Employee Benefit Plan and applicable law. Subject to availability, Employee will be allowed to continue to use, on the same basis as Employee has used in the past, the Company’s corporate memberships in clubs and associations in further of his duties of EDPA and EDPA will bear all associated expenses with such usage.

5.    Termination. This Agreement and Employee’s employment may be terminated prior to December 31, 2023 in one of the following ways:

(a)    Termination by the Company for Cause. The Company, by the Chairman, President and CEO, shall be entitled to terminate the Agreement and to terminate the employment of the Employee, which will also terminate Employee’s position as President of the EDPA, for Cause effective upon the giving of written notice after the Company has knowledge of the event constituting Cause. The term “Cause” shall be limited to the following grounds:

(i)    The Employee’s engagement in conduct amounting to fraud or dishonesty against the Company;

(ii)    The Employee’s refusal to follow the reasonable directions of the Chairman, President and CEO of the Company or the Board of Directors of the EDPA;

(iii)    The Employee’s failure to perform the essential functions of the Employee’s position;

(iv)    The Employee’s engagement in unethical conduct;

(v)    The Employee’s violation of the law in the course of the performance of the duties;

(vi)    The Employee’s conviction of a felony, or for any crime involving moral turpitude, dishonesty, breach of trust or unethical business conduct; or

(vii)    The Employee’s violation of any Company or EDPA policy that would warrant immediate termination of employment.

(b)    Voluntary Termination by the Employee. The Employee may voluntarily terminate the Agreement and Employee’s employment by providing the Company written notice at least sixty (60) days before termination. The Company shall have the right at any time during such 60 day notice period, to relieve the Employee of his offices, duties, and responsibilities and to place him on a paid leave-of-absence status, provided that during such notice period the Employee shall remain a full-time employee of the Company and shall continue to receive his then current salary compensation and other benefits as provided in this Agreement.

2


(c)    Termination for Death or Disability. In the event of the Employee’s death, the Termination Date shall be the date of Employee’s death. In the event Employee shall be unable to perform an essential function of his duties hereunder by virtue of illness or physical or mental incapacity (from any cause or causes whatsoever, all causes being herein referred to as “Disability”) and Employee shall fail to perform such essential function of his duties for 180 contiguous days, the Company shall have the right to terminate Employee’s employment hereunder at the end of any calendar month during the continuance of such Disability upon written notice to him.
