Southern Company (SOJC) lifts profit in Q2 2026 update
The Southern Company and its utility subsidiaries reported higher profitability for the quarter ended June 30, 2026. Consolidated operating revenues were $6,977 million, essentially flat with 2025, while net income attributable to Southern Company increased to $1,174 million from $880 million. Diluted earnings per share rose to $1.03 from $0.79, aided by lower income taxes and higher equity-method earnings.

Alabama Power and Georgia Power generated higher year‑to‑date net income, while Southern Power recorded a net loss attributable to Southern Power of $22 million for the first half, compared with income of $138 million in 2025. Common shares outstanding for The Southern Company were 1,150,362,966 at June 30, 2026.

Key Terms

5 terms
Allowance for funds used during construction financial
"Allowance for equity funds used during construction | 128 | 80"
Allowance for funds used during construction (AFUDC) is the accounting practice of adding the cost of borrowing money and using company funds while building long-term assets to the value of that asset instead of treating it as an immediate expense. For investors, AFUDC matters because it boosts reported profits and increases the company’s asset base today while deferring financing costs to future periods, similar to adding construction loan interest to the price of a house under renovation.
Asset retirement obligation financial
"Regulatory assets – asset retirement obligations | 353 | 353"
A liability recorded for the future cost to retire, dismantle or clean up a long-lived asset — for example removing an oil rig, closing a mine, or decommissioning a plant. Investors care because it reduces reported profit and ties up capital: companies must estimate and set aside money now for a known future expense, and changes to that estimate can swing earnings, debt ratios and the company’s cash needs much like setting aside savings to repair or return a rented property later.
Integrated resource plan regulatory
"2023 IRP Update | Georgia Power's updated IRP filed in 2023"
An integrated resource plan is a utility’s long-term roadmap showing how it will meet future electricity needs using a mix of power sources, energy efficiency, demand reductions and storage while balancing cost, reliability and regulatory requirements. Like a household budget that plans income, bills and savings, the plan reveals expected investments, operating costs and risks, so investors use it to assess future capital spending, potential rate changes and long-term profitability.
Production tax credit financial
"PTC | Production tax credit"
A production tax credit is a government benefit that pays producers a fixed amount for each unit they make or sell — for example a set payment per megawatt-hour of electricity or per barrel of a commodity. It matters to investors because it directly raises a project’s cash flow and lowers the effective cost of production, much like a per‑unit coupon, which can change profitability, valuation and the attractiveness of financing or new investment.
Variable interest entity financial
"VIE | Variable interest entity"
A variable interest entity (VIE) is a company structure where one party controls another company’s operations and economic outcomes through contracts or special arrangements instead of owning a majority of its voting shares. For investors, VIEs matter because the controlling party’s financial results, debts and risks can appear in the controller’s reports even though ownership looks separate, so understanding VIEs helps assess true exposure, governance limits and transparency—like spotting a puppet controlled by strings rather than direct ownership.

The following unaudited notes to the condensed financial statements are a combined presentation; however, information contained herein relating to any individual Registrant is filed by such Registrant on its own behalf and each Registrant makes no representation as to information related to the other Registrants. The table below indicates the Registrants to which each note applies.

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 at December 31, 2025 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, 2026 and 2025. Certain information and 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, operating results for the periods presented are not necessarily indicative of the operating results to be expected for the full year.
The preparation of financial statements in conformity with GAAP requires the use of estimates, and the actual results may differ from those estimates. 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 both June 30, 2026 and December 31, 2025 was as follows:
| Goodwill | ||||||||
| (in millions) | ||||||||
| Southern Company | $ | |||||||
| Southern Company Gas: | ||||||||
| Gas distribution operations | $ | |||||||
| Gas marketing services | ||||||||
| Southern Company Gas total | $ | |||||||
Goodwill is not amortized but is subject to an annual impairment test during the fourth quarter of each year, or more frequently if goodwill impairment indicators exist.

Natural Gas for Sale
With the exception of Nicor Gas, Southern Company Gas records natural gas inventories on a weighted average cost basis. For any declines in market prices below the weighted average cost considered to be non-temporary, an adjustment is recorded to reduce the value of natural gas inventories to market value. 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.
Southern Company Gas recorded no material adjustments to natural gas inventories for either period presented. Nicor Gas' inventory decrements that occurred during the year have been restored as of June 30, 2026.
Asset Retirement Obligations
See BUSINESS – "Regulation – Federal Power Act" in Item 1 and Note 6 to the financial statements in Item 8 of the Form 10-K for additional information.
On April 16, 2026, the FERC issued a surrender order for Georgia Power's Langdale and Riverview hydroelectric projects, which includes dam removal obligations and other post-dam removal activities. As a result, in June 2026, Georgia Power recorded AROs of $46 million.

The wholesale MB fuel cost recovery was immaterial
Alabama Power
Power to the People Act
In December 2025, the Alabama PSC issued a consent order to keep retail rates stable through 2027. On April 2, 2026, the State of Alabama enacted legislation providing that retail base rates established and in place on October 1, 2026 may not be increased before January 1, 2029 for utilities that are regulated by the Alabama PSC and that provide retail electric service. The ultimate outcome of this matter cannot be determined at this time.
Reliability Reserve Accounting Order
In accordance with the notification provided to the Alabama PSC through its annual Rate RSE filing indicating plans to use $60 million of the reliability reserve, Alabama Power utilized $40 million of its reliability reserve during the first six months of 2026 for reliability-related transmission, distribution, and generation expenses. At June 30, 2026, Alabama Power's reliability reserve balance was $144 million.
Environmental Accounting Order
As a result of the planned conversion of Plant Barry Unit 5 from coal to natural gas, the unit's net book value no longer meets the criteria to be considered probable of abandonment, and, in the first quarter 2026, approximately $307

Georgia Power
Integrated Resource Plans
Certification Requests
On March 25, 2026, Georgia Interfaith Power & Light, Park Avenue Baptist Church, Unitarian Universalist Church of Savannah, Sierra Club, Adrien Webber, and Southern Alliance for Clean Energy filed a petition with the Fulton County Superior Court appealing the Georgia PSC's December 19, 2025 approval of Georgia Power's request for certification of resources totaling 9,885 MWs (2025 All-Source Certification). The petition requests a reversal of the 2025 All-Source Certification, including a decertification of at least 757 MWs of resources. Georgia Power intervened in the proceeding, and both the Georgia PSC and Georgia Power filed motions to dismiss on April 24, 2026 and June 23, 2026, respectively. Georgia Power believes the appeal has no merit; however, the ultimate outcome of this matter cannot be determined at this time.
On June 2, 2026, the FERC approved two affiliate PPAs with Southern Power procured under the 2022 IRP. These affiliate PPAs began in June 2026 with capacities of 638 MWs and 74 MWs. See Note (F) under "Georgia Power Lease Modification" for additional information.
2025 IRP
Pursuant to the final order for Georgia Power's 2025 IRP, on June 9, 2026, Georgia Power initiated a request for proposals for 2,000 MWs to 6,000 MWs of capacity resources with projected CODs or delivery commencement dates in 2032 and 2033.
Fuel Cost Recovery
On each of March 13, 2026, April 15, 2026, and May 14, 2026, Georgia Power filed an Interim Fuel Rider (IFR) notification and plan informing the Georgia PSC that Georgia Power's under recovered fuel balance accumulated since May 31, 2023 exceeded $200 million, as established in a Georgia PSC stipulation approved in 2023, as of February 28, 2026, March 31, 2026, and April 30, 2026, respectively. Georgia Power did not propose a fuel cost recovery rate change pursuant to these IFR notifications and plans.
On May 28, 2026, the Georgia PSC approved a stipulation among Georgia Power, the staff of the Georgia PSC, and certain intervenors to decrease annual fuel billings by 12.9 %, or approximately $394 million, effective June 1, 2026. Under the approved stipulation, Georgia Power is required to file for an adjustment to its fuel cost recovery rates under an IFR prior to the next fuel case, subject to a maximum 40 % cumulative change, if its under or over recovered fuel balance accumulated since May 31, 2026 exceeds $300 million. Within 30 days of the filing, the Georgia PSC will approve, modify, or reject any proposed fuel cost recovery rate adjustment. Georgia Power is scheduled to file its next fuel case no later than February 28, 2029. Changes in fuel rates have no significant effect on Georgia Power's net income but impact the related operating cash flows.
Storm Damage Recovery
On May 28, 2026, the Georgia PSC approved a stipulation among Georgia Power, the staff of the Georgia PSC, and certain intervenors regarding Georgia Power's recovery of storm restoration costs. Under the stipulation, the Georgia PSC approved the following:
•Recovery of $31 million annually for storm restoration costs incurred after December 31, 2025.
•Recovery of Georgia Power's adjusted regulatory asset balance totaling $869 million, as determined through the proceedings and stipulation, related to storm damage as of December 31, 2025 over a period of 67 months from June 1, 2026 through December 31, 2031, or $156 million annually.
Additionally, the stipulation provided for the treatment of the Internal Revenue Code §45U PTCs generated from Georgia Power's nuclear generating facilities in 2024 and 2025, in which Georgia Power agreed to use $77 million of these tax credits for the benefit of customers.

In accordance with the PEP rate schedule, the increase became effective with the first billing cycle of January 2026.

On March 9, 2026, in compliance with its IRP requirements, Mississippi Power submitted its mid-point update to its 2024 IRP to the Mississippi PSC, indicating that the retirement dates of Plant Daniel Unit 2 and Plant Watson Unit 4 will extend beyond 2028.
On July 7, 2026, the Mississippi PSC approved a request from Mississippi Power to convert either Plant Daniel Unit 1 or Unit 2 from a coal-fired unit to a natural gas-fired unit. Conversion of the declared unit is projected to be completed in 2029.
The remaining net book value of Plant Daniel Units 1 and 2 was approximately $481 million at June 30, 2026, and Mississippi Power is continuing to depreciate these units using approved rates. Until a unit is declared to be converted, Mississippi Power is unable to determine what portion of the net book value will remain in service upon a unit conversion. Mississippi Power expects to reclassify the remaining net book value of assets no longer in service upon a unit conversion or retirement to a regulatory asset to be amortized over a period to be determined by the Mississippi PSC in future proceedings, consistent with a 2020 order. The ultimate outcome of this matter cannot be determined at this time.
Environmental Compliance Overview Plan
On April 14, 2026, the Mississippi PSC approved Mississippi Power's annual ECO Plan filing for 2026, resulting in a $2 million annual increase in revenues effective with the first billing cycle of May 2026.
Ad Valorem Tax Adjustment
On June 12, 2026, Mississippi Power submitted its annual ad valorem tax adjustment filing for 2026 to the Mississippi PSC, which requested a $7 million annual increase in revenues. The ultimate outcome of this matter cannot be determined at this time.
System Restoration Rider
On June 18, 2026, the Mississippi PSC approved Mississippi Power's annual SRR filing for 2026, with no change in retail rates. Mississippi Power's minimum annual SRR accrual increased from $13.5 million to $13.7 million.
Reliability Reserve Accounting Order
On March 16, 2026, through its annual PEP Evaluation Report, Mississippi Power notified the Mississippi PSC of its intent to use a portion of its $59 million retail reliability reserve balance during 2026. On June 18, 2026, the Mississippi PSC approved the annual PEP filing which allowed for the use of approximately $7 million of the reliability reserve balance, which Mississippi Power utilized for reliability-related generation, transmission, and distribution expenses during the first six months of 2026. At June 30, 2026, Mississippi Power's retail reliability reserve balance was $52 million. See "Performance Evaluation Plan" herein for information regarding Mississippi Power's annual PEP filing.
Excess Accumulated Deferred Income Tax Accounting Order
On June 18, 2026, the Mississippi PSC approved approximately $21 million associated with certain federal excess accumulated deferred income taxes resulting from the Tax Reform Legislation to be credited back to customers over an 18-month period starting with the first billing cycle of July 2026.

Southern Company Gas
Rate Proceedings
On June 16, 2026, in connection with Nicor Gas' 2023 general base rate case proceeding, the Illinois Appellate Court determined that the Illinois Commission did not provide sufficient support for its disallowance of $43 million of Nicor Gas' planned capital investments that were expected to be completed by December 31, 2024. As the disallowance related to planned capital investments for which costs had not yet been incurred, it was not included in the pre-tax charge to income recorded in 2023. This matter remains subject to further proceedings before the Illinois Commission and had no impact on the current period financial statements.
On July 21, 2026, Nicor Gas filed a petition for leave to appeal with the Illinois Supreme Court related to the capital structure approved in Nicor Gas' 2023 general base rate case proceeding. The Illinois Supreme Court is expected to rule on the petition on September 30, 2026.
The ultimate outcome of these matters cannot be determined at this time.
(C) CONTINGENCIES
See Note 3 to the financial statements in Item 8 of the Form 10-K for information relating to various lawsuits and other contingencies.
General Litigation Matters
The Registrants are involved in various 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 intend to dispute the allegations raised in and vigorously defend against the pending legal challenges discussed below; however, the ultimate outcome of each of these matters cannot be determined at this time.
Southern Company
In July 2025, a purported class action complaint was filed in the U.S. District Court for the District of Maryland against two nuclear consulting companies and all U.S. commercial nuclear power operators, or affiliated entities, including Southern Company. The purported class of plaintiffs includes all persons employed in nuclear power generation by the defendants, including nuclear operators, nuclear engineers, and nuclear technicians, from May 1, 2003 to the present. The complaint alleges that, since at least May 2003, the nuclear power industry conspired to fix and suppress employee compensation for nuclear power generation employees in violation of federal antitrust law. Although not named as defendants, other entities are accused of having participated in the conspiracy alleged by the plaintiffs. The plaintiffs seek to recover, among other relief, unspecified monetary damages, including treble damages and attorneys' fees, and injunctive relief. In October 2025, Southern Company moved to dismiss the complaint. In November 2025, the plaintiffs filed an amended complaint naming Southern Nuclear, among others, as a defendant. In December 2025, Southern Company and Southern Nuclear filed a motion to dismiss the amended complaint. An adverse outcome could have a material impact on Southern Company's financial statements.
Alabama Power
In 2022, Mobile Baykeeper filed a citizen suit in the U.S. District Court for the Southern District of Alabama alleging that Alabama Power's plan to close the Plant Barry surface impoundment utilizing a closure-in-place methodology violates the Resource Conservation and Recovery Act (RCRA) and regulations governing CCR. Among other relief requested, Mobile Baykeeper sought a declaratory judgment that the RCRA and regulations governing CCR were being violated, preliminary and injunctive relief to prevent implementation of Alabama Power's closure plan, and the development of a closure plan that satisfies regulations governing CCR requirements.

(UNAUDITED)
Later in 2022, Alabama Power filed a motion to dismiss the case. In 2024, the lawsuit was dismissed without prejudice by the U.S. District Court judge. Later in 2024, the U.S. District Court judge denied a motion to reconsider filed by the plaintiff, and the plaintiff filed a notice of appeal in the U.S. Court of Appeals for the Eleventh Circuit challenging the denial of the motion to reconsider the order of dismissal. On May 18, 2026, the U.S. Court of Appeals for the Eleventh Circuit overturned the dismissal and remanded the case to the U.S. District Court for further proceedings.
In 2023, the EPA issued a Notice of Potential Violations (NOPV) associated with Alabama Power's plan to close the Plant Barry surface impoundment. In 2024, Alabama Power reached a settlement with the EPA resolving two of the three allegations in the NOPV related to the groundwater monitoring system and the emergency action plan at the Plant Barry surface impoundment. The settlement did not resolve the EPA's allegation relating to Alabama Power's plan to close the Plant Barry surface impoundment. Alabama Power has affirmed to the EPA its position that it is in compliance with CCR requirements.
In July 2025, Coosa Riverkeeper filed a citizen suit in the U.S. District Court for the Northern District of Alabama alleging that Alabama Power's closure of the Plant Gadsden surface impoundment utilizing a closure-in-place methodology violates the RCRA and regulations governing CCR. Among other relief requested, Coosa Riverkeeper seeks declaratory judgment that Alabama Power is in violation of the RCRA and regulations governing CCR, and preliminary and injunctive relief to require Alabama Power to close the CCR unit and operate a groundwater monitoring system in a different manner to satisfy the RCRA and the regulations governing CCR requirements. In September 2025, Alabama Power filed a motion to dismiss the citizen suit.
These matters could have a material impact on Alabama Power's and Southern Company's financial statements, including ARO estimates and cash flows. See Note 6 to the financial statements in Item 8 of the Form 10-K for a discussion of Alabama Power's ARO liabilities.
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 remediation 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 $15 million and $14 million at June 30, 2026 and December 31, 2025, 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.
Southern Company Gas' environmental remediation liability was $215 million and $227 million at June 30, 2026 and December 31, 2025, respectively, based on the estimated cost of environmental investigation and remediation at known former manufactured gas plant operating sites.
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.

(D) REVENUE FROM CONTRACTS WITH CUSTOMERS AND LEASE INCOME
Revenue from Contracts with Customers
The Registrants generate revenues from a variety of sources, some of which are not accounted for as revenue from contracts with customers, such as leases, derivatives, and certain cost recovery mechanisms. Included in the wholesale electric revenues of the traditional electric operating companies and Southern Power are revenues associated with affiliate transactions. These revenues are generated through long-term PPAs or short-term energy sales made in accordance with the IIC, as approved by the FERC. Amounts related to these affiliate revenues are eliminated in consolidation for Southern Company. See Note 1 to the financial statements under "Affiliate Transactions" and "Revenues" in Item 8 of the Form 10-K for additional information. See "Lease Income" herein and Note (J) for additional information on revenue accounted for under lease and derivative accounting guidance, respectively.

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, 2026 and December 31, 2025:
| Southern Company | Alabama Power | Georgia Power | Mississippi Power | Southern Power | Southern Company Gas | |||||||||||||||

| At June 30, 2026 | $ | $ | $ | $ | $ | $ | ||||||||||||||
| At December 31, 2025 | ||||||||||||||||||||
Contract assets for Georgia Power primarily relate to unregulated service agreements, where payment is contingent on project completion, and retail customer fixed bill programs, where 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 primarily relate to cash collections recognized in advance of revenue for unregulated service agreements. Southern Company Gas' contract assets relate to work performed on an energy efficiency enhancement and upgrade contract with the U.S. General Services Administration. Southern Company Gas received cash advances totaling approximately $68 million from a third-party financial institution to fund work performed. These advances have been accounted for as long-term debt on the balance sheets. See Note 1 to the financial statements under "Affiliate Transactions" in Item 8 of the Form 10-K for additional information regarding the construction contract. At June 30, 2026 and December 31, 2025, Southern Company's unregulated distributed generation business had contract assets of $92 million and $63 million, respectively, and contract liabilities of $199 million and $132 million, respectively, for outstanding performance obligations, all of which are expected to be satisfied within one year.
Revenues recognized in the three and six months ended June 30, 2026, which were included in contract liabilities at December 31, 2025, were $26 million and $80 million, respectively, for Southern Company, $7 million and $18 million, respectively, for Georgia Power, and immaterial
Remaining Performance Obligations
Southern Company's subsidiaries may enter into long-term contracts with customers in which revenues are recognized as performance obligations are satisfied over the contract term. For the traditional electric operating companies and Southern Power, these contracts primarily relate to PPAs whereby electricity and generation capacity are provided 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

(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 Company
At June 30, 2026 and December 31, 2025, Southern Holdings had equity method investments totaling $156 million and $124 million, respectively, primarily related to investments in venture capital funds focused on energy and utility investments. The net earnings (losses) from these investments totaled $45 million and $(14 ) million for the three months ended June 30, 2026 and 2025, respectively, and $48 million and $(20 ) million for the six months ended June 30, 2026 and 2025, respectively.
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
At June 30, 2026 and December 31, 2025, SP Solar had total assets of $5.1 billion and $5.2 billion, respectively, total liabilities of $364 million and $360 million, respectively, and noncontrolling interests of $907 million and $918 million, respectively. Cash distributions from SP Solar are allocated 67 % to Southern Power and 33 % to the limited partner 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.
Southern Power consolidates SP Solar, as the primary beneficiary, since it controls the most significant activities of the entity, including operating and maintaining its assets. Certain transfers and sales of the assets in the VIE 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, 2026 and December 31, 2025, the other VIEs had total assets of $1.5 billion and $1.6 billion, respectively, total liabilities of $259 million and $236 million, respectively, and noncontrolling interests of $563 million and $617 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.

Southern Company extended the maturity date of its multi-year credit agreement from 2027 to 2028, (iii) Georgia Power extended the maturity date of its multi-year credit arrangement from 2030 to 2031, and (iv) Mississippi Power extended the maturity date of its multi-year credit arrangement from 2027 to 2029. In May 2026, Alabama Power and Southern Company Gas Capital, along with Nicor Gas, extended the maturity date of each of their respective multi-year credit arrangements from 2030 to 2031. In May and June 2026, SEGCO amended its credit arrangements to extend the maturity dates from 2026 to 2027.
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, Nicor Gas, and SEGCO, contain covenants that limit debt levels and contain cross-acceleration provisions to other indebtedness (including guarantee obligations) that are restricted only to the indebtedness of the individual company. The 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, 2026, 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 certain revenue bonds of the traditional electric operating companies and the commercial paper programs of the Registrants, Nicor Gas, and SEGCO. At June 30, 2026, outstanding variable rate demand revenue bonds of the traditional electric operating companies with allocated liquidity support totaled approximately $1.5 billion (comprised of approximately $796 million at Alabama Power, $667 million at Georgia Power, and $58 million at Mississippi Power). In addition, at June 30, 2026, Georgia Power had approximately $210 million of fixed rate revenue bonds outstanding that are required to be remarketed within the next 12 months. Variable rate demand revenue bonds and fixed rate revenue bonds required to be remarketed within the next 12 months are classified as long-term debt on the balance sheets as a result of available long-term committed credit.

(a)The total number of shares sold under this forward sale contract is 3,130,641 , of which 1,070,641 shares were settled during the six months ended June 30, 2026. The other 2,060,000 shares were settled in December 2025.
(b)The total number of shares sold under this forward sale contract is 1,940,548 , of which the remaining 1,340,454 shares were sold subsequent to June 30, 2026. The initial forward price was determined after the completion of sales by the forward seller in July 2026.
As of June 30, 2026, Southern Company had entered into separate forward sale contracts with forward purchasers for a total of 49,885,779 shares of common stock under the 2024 ATM Program, all of which had been sold by the forward sellers, and 7,557,278 shares of common stock under the 2026 ATM Program, of which 6,216,824 shares had been sold by the forward sellers.

The net proceeds from the shares settled during the six months ended June 30, 2026 were approximately $2.5 billion.
As of June 30, 2026, the total number of shares sold remaining under the forward sale contracts subject to settlement at a future date is 11,483,995 . Each initial forward price is subject to adjustment under certain circumstances as specified in the respective forward sales contracts.

Earnings per Share
For Southern Company, the difference in computing basic and diluted EPS is attributable to awards outstanding under stock-based compensation plans, forward sale contracts pursuant to the equity distribution agreement, convertible senior notes, and equity units. EPS dilution resulting from stock-based compensation plans, forward sale contracts, and the equity units is determined using the treasury stock method. EPS dilution resulting from the convertible senior notes is determined using the net share settlement method. See "Equity Distribution Agreement"

Georgia Power Lease Modification
See Note 9 to the financial statements in Item 8 of the Form 10-K for information on Georgia Power's leases. In June 2026, Georgia Power recognized a lease modification related to an existing affiliate PPA with Southern Power which converted from an operating lease to a finance lease upon its approval by the FERC. As a result, Georgia Power removed from its balance sheet operating lease right-of-use assets, net of amortization of $179 million and lease obligations of $197 million maturing through 2030 and recorded finance lease right-of-use assets of $1.3 billion and lease obligations of $1.3 billion maturing through 2045. See Note (B) under "Georgia Power – Integrated Resource Plans – Certification Requests" for additional information.
(G) INCOME TAXES
See Note 10 to the financial statements in Item 8 of the Form 10-K for additional tax information.
Cash Paid for Income Taxes
Alabama Power, Georgia Power, and Southern Power have entered into transferability agreements with non-affiliated parties to sell ITCs and PTCs at a discount to the generated credit value in 2024, 2025, and 2026. The discount is recorded as a reduction in tax credits recognized in the financial statements and does not have a material impact on results of operations. During the first six months of 2026, Alabama Power, Georgia Power, and Southern Power received cash of $39 million, $91 million, and $49 million, respectively, from credits transferred. The Southern Company system continues to explore the ability to efficiently monetize its tax credits through third-party transfer agreements.
During the first six months of 2026, pursuant to certain joint ownership agreements, Georgia Power paid $83 million to the other Vogtle Owners for advanced nuclear PTCs for Plant Vogtle Units 3 and 4. The gain was recognized as an income tax benefit and was immaterial.
Effective Tax Rate
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.
Details of significant changes in the effective tax rate for the applicable Registrants are provided herein.
Southern Company
Southern Company's effective tax rate was 14.1 % for the six months ended June 30, 2026 compared to 21.1 % for the corresponding period in 2025. The effective tax rate decrease was primarily due to a decrease in charges to a

(UNAUDITED)
valuation allowance on certain state tax credit carryforwards at Georgia Power, an increase in federal PTCs at Southern Power, and an increase in amortization of federal PTCs at Georgia Power, partially offset by a decrease in the flowback of excess state deferred income taxes at Georgia Power.
Georgia Power
Georgia Power's effective tax rate was 14.3 % for the six months ended June 30, 2026 compared to 21.7 % for the corresponding period in 2025. The effective tax rate decrease was primarily due to a decrease in charges to a valuation allowance on certain state tax credit carryforwards and an increase in amortization of federal PTCs and ITCs, partially offset by a decrease in the flowback of excess state deferred income taxes.
Southern Power
Southern Power's effective tax benefit rate was (85.1 )% for the six months ended June 30, 2026 compared to (7.0 )% for the corresponding period in 2025. The effective tax benefit rate increase was primarily due to an increase in federal PTCs resulting from Southern Power's purchase of the noncontrolling membership interests in the SP Wind tax equity partnership, as well as a change in pre-tax earnings attributable to Southern Power, including the impact of accelerated depreciation related to wind repowering projects. See Note (K) under "Southern Power – Wind Repowering Projects" and Notes 5 and 15 to the financial statements under "Depreciation and Amortization – Southern Power" and "Southern Power – Purchase of Renewable Facility Interests," respectively, in Item 8 of the Form 10-K for additional information.
Southern Company Gas
Southern Company Gas' effective tax rate was 23.5 % for the six months ended June 30, 2026 compared to 23.7 % for the corresponding period in 2025. The effective tax rate decrease was primarily due to an increase in tax benefits related to certain state tax filing positions, offset by a decrease in the flowback of excess state deferred income taxes.
(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. No mandatory contributions to the qualified pension plan are anticipated for the year ending December 31, 2026. 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.
See Note 11 to the financial statements in Item 8 of the Form 10-K for additional information.
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, 2026 and 2025 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 Company's investments, available for sale relate to a wholly-owned subsidiary that insures various risk exposures of Southern Company and its subsidiaries. Corporate and municipal bonds, government agency securities, and commercial paper are valued using pricing models maximizing the use of observable inputs for similar securities, including basing value on yields currently available on comparable securities of issues with similar credit ratings. Mortgage- and asset-backed securities are valued through an analysis of the underlying assets and a review of the documentation, including financials, the manager's valuation methodology in valuing their underlying assets, the types of assets and risks involved, and the investor's exit and termination parameters.
Southern Power has contingent payment obligations related to two of its acquisitions whereby it is primarily obligated to make generation-based payments to the seller, commencing at the commercial operation of each facility
71

NOTES TO THE CONDENSED FINANCIAL STATEMENTS (Continued)
(UNAUDITED)
and continuing through 2026 and 2036, respectively. The obligations are primarily categorized as Level 3 under Fair Value Measurements as the fair value is determined using significant unobservable inputs for the forecasted facility's generation in MW-hours, as well as other inputs such as a fixed dollar amount per MW-hour, and a discount rate. The fair value of the obligations reflects the net present value of expected payments and any periodic change arising from forecasted generation is expected to be immaterial.
Southern Power also has payment obligations through 2040 whereby it must reimburse the transmission owners for interconnection facilities and network upgrades constructed to support connection of a Southern Power generating facility to the transmission system. The obligations are categorized as Level 2 under Fair Value Measurements as the fair value is determined using observable inputs for the contracted amounts and reimbursement period, as well as a discount rate. The fair value of the obligations reflects the net present value of expected payments.
"Other investments" primarily includes 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.
At June 30, 2026, the fair value measurements of private market 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 $211 million and unfunded commitments related to the private market investments totaled $94 million. Private market investments include high-quality private equity funds across several market sectors, funds that invest in real estate assets, and private credit funds. Private market funds do not have redemption rights. Distributions from these funds will be received as the underlying investments in the funds are liquidated.
At June 30, 2026, other financial instruments for which the carrying amount did not equal fair value were as follows:

(*)The carrying amount of Southern Company Gas' long-term debt includes fair value adjustments from the effective date of the 2016 merger with Southern Company. Southern Company Gas amortizes the fair value adjustments over the remaining lives of the respective bonds, the latest being through 2043.
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.
(J) DERIVATIVES
The Registrants 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. 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 the 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 Subsidiary Registrants 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 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 in the event of warmer-than-normal weather. Exchange-traded options are carried at fair value, with changes reflected in natural gas 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 natural gas revenues.
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 an approved cost recovery mechanism.
•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, 2026, 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 Purchased mmBtu | Longest Hedge Date | Longest Non-Hedge Date | |||||||||||||||
| (in millions) | |||||||||||||||||
Southern Company(*) | 2030 | 2029 | |||||||||||||||
| Alabama Power | 2029 | 2026 | |||||||||||||||

| Southern Power | 2030 | 2026 | |||||||||||||||
Southern Company Gas(*) | 2028 | 2029 | |||||||||||||||
(*)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 85 million mmBtu long natural gas positions and 10 million mmBtu short natural gas positions at June 30, 2026, which is also included in Southern Company's total volume.
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 15 million mmBtu for Southern Company, which includes 4 million mmBtu for Alabama Power, 6 million mmBtu for Georgia Power, 2 million mmBtu for Mississippi Power, and 3 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, 2027 are immaterial
Interest Rate Derivatives
Southern Company and certain subsidiaries may enter into interest rate derivatives to hedge exposure to changes in interest rates. 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.

Foreign Currency Derivatives
Southern Company and certain subsidiaries 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. 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, including foreign currency gains or losses arising from changes in the U.S. currency exchange rates. Southern Company has elected to exclude the cross-currency basis spread from the assessment of effectiveness in the fair value hedges of its foreign currency risk and record any difference between the change in the fair value of the excluded components and the amounts recognized in earnings as a component of OCI.

Derivative Financial Statement Presentation and Amounts
The Registrants 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. The fair value amounts of derivative assets and liabilities on the balance sheets are presented net to the extent that there are netting arrangements or similar agreements with the counterparties.

Contingent Features
The Registrants 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. Generally, collateral may be provided by a Southern Company guaranty, letter of credit, or cash. At June 30, 2026, the Registrants had no collateral posted with derivative counterparties to satisfy these arrangements.
For Southern Company, the fair value of foreign currency derivative liabilities and 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 $31 million at June 30, 2026. For the traditional electric operating companies and Southern Power, 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
Alabama Power and Southern Power maintain accounts with certain regional transmission organizations to facilitate financial derivative transactions and they may be required to post collateral based on the value of the positions in these accounts and the associated margin requirements. At June 30, 2026, cash collateral posted in these accounts was immaterial
The Registrants are exposed to losses related to financial instruments in the event of counterparties' nonperformance. The Registrants generally enter into agreements and material transactions with counterparties that have investment grade credit ratings by Moody's, S&P, or Fitch 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.
Southern Company Gas uses established credit policies to determine and monitor the creditworthiness of counterparties, including requirements to post collateral or other credit security, as well as the quality of pledged collateral. Collateral or credit security is most often in the form of cash or letters of credit from an investment-grade financial institution, but may also include cash or U.S. government securities held by a trustee. Prior to entering a physical transaction, Southern Company Gas assigns its 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.
The Registrants do not anticipate a material adverse effect on their respective financial statements as a result of counterparty nonperformance.

(L) SEGMENT AND RELATED INFORMATION
See Note 16 to the financial statements in Item 8 of the Form 10-K for additional information.
Southern Company
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. The traditional electric operating companies are vertically integrated utilities providing electric service in three Southeastern states. Southern Power develops, constructs, acquires, owns, operates, and manages power generation assets, including battery energy storage projects, and sells electricity at market-based rates in the wholesale market. Southern Company Gas distributes natural gas through its natural gas distribution utilities and is involved in several other complementary businesses including gas pipeline investments and gas marketing services.
Southern Company's reportable business 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 distribution of natural gas and other complementary products and services by Southern Company Gas. While the traditional electric operating companies represent three separate operating segments, they are vertically integrated utilities providing electric service to retail customers, as well as wholesale customers, in the Southeast and have been aggregated into one reportable segment. The "All Other" presentation includes the Southern Company parent entity, which does not allocate operating expenses to business segments, and operating segments below the quantitative threshold for separate disclosure. These operating segments include providing distributed energy and resilience solutions and deploying microgrids for commercial, industrial, governmental, and utility customers, as well as investments in telecommunications. Revenues from sales by Southern Power to the traditional electric operating companies were $92 million and $192 million for the three and six months ended June 30, 2026, respectively, and $114 million and $229 million for the three and six months ended June 30, 2025, respectively. All other inter-segment revenues were immaterial for all periods presented.
Southern Company's CODM utilizes segment net income, including variances to budget and forecasts, to assess performance and is not provided with segment expense information. To achieve the consolidated net income goal, Southern Company's CODM sets net income expectations for each operating segment, which is expected to monitor its expenses in order to achieve its assigned net income target. Therefore, Southern Company has no reportable significant segment expenses.

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), 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 distribution of natural gas and sale of other complementary products and services by Southern Company Gas. Alabama Power, Georgia Power, and Mississippi Power each operate with one reportable business segment, since substantially all of their business is providing electric service to customers. Southern Power also operates its business with one reportable business segment, the sale of electricity in the competitive wholesale market. Southern Company Gas' reportable segments are gas distribution operations, gas pipeline investments, 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. Southern Company Gas also continues to focus on several operating metrics, including customer count and volumes of natural gas sold. For Southern Power, key performance 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
Alabama Power
In December 2025, the Alabama PSC issued a consent order to keep retail rates stable through 2027. On April 2, 2026, the State of Alabama enacted legislation providing that retail base rates established and in place on October 1, 2026 may not be increased before January 1, 2029 for utilities that are regulated by the Alabama PSC and that provide retail electric service. The ultimate outcome of this matter cannot be determined at this time. See Note 2 to the financial statements under "Alabama Power" in Item 8 of the Form 10-K for additional information.
Georgia Power
On May 28, 2026, the Georgia PSC approved a stipulation among Georgia Power, the staff of the Georgia PSC, and certain intervenors regarding Georgia Power's separate filings in February 2026 associated with recovery of fuel and storm restoration costs. The approved stipulation decreased annual fuel billings by 12.9 %, or approximately $394 million, effective June 1, 2026. Under the stipulation, the Georgia PSC approved the following related to storm restoration costs:
•Recovery of $31 million annually for storm restoration costs incurred after December 31, 2025.
•Recovery of Georgia Power's adjusted regulatory asset balance totaling $869 million, as determined through the proceedings and stipulation, related to storm damage as of December 31, 2025 over a period of 67 months from June 1, 2026 through December 31, 2031, or $156 million annually.
Additionally, the stipulation provided for the treatment of the Internal Revenue Code §45U PTCs generated from Georgia Power's nuclear generating facilities in 2024 and 2025, in which Georgia Power agreed to use $77 million of these tax credits for the benefit of customers.
See Note (B) to the Condensed Financial Statements under "Georgia Power" herein for additional information.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS (Continued)
Mississippi Power
On June 18, 2026, the Mississippi PSC approved Mississippi Power's annual retail PEP Evaluation Report for 2026, resulting in an annual increase in revenues of approximately 1.8%, or $20 million, primarily due to increases in investment and depreciation. In accordance with the PEP rate schedule, the increase became effective with the first billing cycle of January 2026. In the PEP filing, the Mississippi PSC approved the use of approximately $7 million of the reliability reserve balance, which Mississippi Power utilized for reliability-related generation, transmission, and distribution expenses during the first six months of 2026. In conjunction with the PEP filing, the Mississippi PSC approved approximately $21 million associated with certain federal excess accumulated deferred income taxes resulting from the Tax Reform Legislation to be credited back to customers over an 18-month period starting with the first billing cycle of July 2026.
See Note (B) to the Condensed Financial Statements under "Mississippi Power" herein for additional information.
Southern Power
In the first quarter 2026, Southern Power committed to development projects to upgrade certain turbines at its existing Franklin and Wansley natural gas facilities, which are projected to add up to 400 MWs of incremental capacity. Commercial operations for the incremental capacity at the natural gas facilities are projected to occur between the second quarter 2029 and the fourth quarter 2030. The ultimate outcome of these matters cannot be determined at this time. In addition, during the first six months of 2026 and subsequent to June 30, 2026, Southern Power placed in service all 200 MWs of the repowering project at the Kay wind facility. See Note (K) to the Condensed Financial Statements under "Southern Power" herein for additional information.
At June 30, 2026, 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 facilities' net book value (or expected in-service value for facilities under construction) as the investment amount was 97% through 2030 and 88% through 2035, with an average remaining contract duration of approximately 12 years.
Southern Company Gas
On June 16, 2026, in connection with Nicor Gas' 2023 general base rate case proceeding, the Illinois Appellate Court determined that the Illinois Commission did not provide sufficient support for its disallowance of $43 million of Nicor Gas' planned capital investments that were expected to be completed by December 31, 2024. As the disallowance related to planned capital investments for which costs had not yet been incurred, it was not included in the pre-tax charge to income recorded in 2023. This matter remains subject to further proceedings before the Illinois Commission and had no impact on the current period financial statements.
On July 21, 2026, Nicor Gas filed a petition for leave to appeal with the Illinois Supreme Court related to the capital structure approved in Nicor Gas' 2023 general base rate case proceeding. The Illinois Supreme Court is expected to rule on the petition on September 30, 2026.
The ultimate outcome of these matters cannot be determined at this time.

Consolidated net income attributable to Southern Company was $1.2 billion ($1.03 per share) in the second quarter 2026 compared to $0.9 billion ($0.80 per share) for the corresponding period in 2025. For year-to-date 2026, consolidated net income attributable to Southern Company was $2.5 billion ($2.24 per share) compared to $2.2 billion ($2.01 per share) for the corresponding period in 2025. The increases were primarily due to increases within retail electric revenues associated with sales growth, higher natural gas revenues associated with base rate increases, decreases in income taxes, and increases in AFUDC equity and earnings from equity method investments, partially offset by increases in depreciation and amortization. Also contributing to the increase in the second quarter 2026 was a decrease in interest expense.

Changes in rates and pricing resulted in decreases in revenues in the second quarter and year-to-date 2026 when compared to the corresponding periods in 2025 primarily due to lower contributions from commercial and industrial customers with variable demand-driven pricing at Georgia Power, partially offset by an increase in Rate CNP Compliance revenues at Alabama Power and higher revenues associated with a tolling arrangement accounted for as a sales-type lease at Mississippi Power. Also partially offsetting the decrease in revenues for year-to-date 2026 were increases in PEP rates at Mississippi Power. See Note 2 to the financial statements under "Alabama Power – Rate CNP Compliance" and "Mississippi Power – Performance Evaluation Plan" in Item 8 of the Form 10-K for additional information.
Changes in sales resulted in increases in revenues in the second quarter and year-to-date 2026 when compared to the corresponding periods in 2025. Weather-adjusted residential KWH sales decreased 0.7% in the second quarter 2026 primarily due to decreased customer usage, partially offset by customer growth. Weather-adjusted residential KWH sales increased 0.1% for year-to-date 2026 primarily due to customer growth, partially offset by decreased customer usage. Weather-adjusted commercial KWH sales increased 7.4% and 6.0% in the second quarter and year-to-date 2026, respectively, primarily due to increased customer usage, largely driven by data centers at Georgia Power. Weather-adjusted industrial KWH sales were flat in the second quarter 2026 primarily due to increases in the primary metals and miscellaneous manufacturing sectors, offset by decreases in the paper, textiles, and chemicals sectors. Weather-adjusted industrial KWH sales increased 0.7% for year-to-date 2026 primarily due to increases in the primary metals, miscellaneous manufacturing, and stone, clay, and glass sectors.

Fuel and other cost recovery revenues decreased $70 million and $21 million in the second quarter and year-to-date 2026, respectively, compared to the corresponding periods in 2025 primarily due to lower recoverable fuel costs. 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. 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.

In the second quarter 2026, wholesale electric revenues were $699 million compared to $681 million for the corresponding period in 2025. The increase was primarily due to an increase in energy revenues associated with a $48 million increase related to the volume of KWHs sold resulting from higher demand, partially offset by a decrease of $27 million related to the average cost per KWH sold primarily resulting from lower fuel and purchased power prices.
For year-to-date 2026, wholesale electric revenues were $1.66 billion compared to $1.43 billion for the corresponding period in 2025. The increase was primarily due to an increase in energy revenues associated with an increase of $123 million related to the volume of KWHs sold resulting from higher demand and $120 million related to the average cost per KWH sold primarily resulting from higher fuel and purchased power prices.
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.

Changes in rates and pricing resulted in increases in revenues in the second quarter and year-to-date 2026 as compared to the corresponding periods in 2025 primarily due to an increase in Rate CNP Compliance revenues resulting from higher recoverable costs. See Note 2 to the financial statements under "Alabama Power – Rate CNP Compliance" in Item 8 of the Form 10-K for additional information.
Changes in sales resulted in a decrease in revenues in the second quarter 2026 and an increase in revenues for year-to-date 2026 as compared to the corresponding periods in 2025. Weather-adjusted residential KWH sales decreased 1.3% in the second quarter 2026 primarily due to a decrease in customer usage. Weather-adjusted residential KWH sales increased 0.5% for year-to-date 2026 primarily due to customer growth. Weather-adjusted commercial KWH sales decreased 0.9% and 0.3% in the second quarter and year-to-date 2026, respectively, primarily due to decreases in customer usage. Industrial KWH sales increased 2.0% and 3.0% in the second quarter and year-to-date 2026, respectively, primarily due to increases in the primary metals and mining sectors, partially offset by decreases in the chemicals and pulp and paper sectors.
Fuel and other cost recovery revenues decreased in the second quarter and year-to-date 2026 as compared to the corresponding periods in 2025 primarily as a result of lower recoverable fuel costs. 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 NDR. 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.

In the second quarter 2026, wholesale revenues from sales to non-affiliates were $85 million compared to $98 million for the corresponding period in 2025. The decrease was primarily due to a decrease in non-fuel revenues from wholesale capacity contracts.
For year-to-date 2026, wholesale revenues from sales to non-affiliates were $202 million compared to $189 million for the corresponding period in 2025. The increase consisted of a $34 million increase in energy revenues due to increases of $27 million related to the volume of KWH sales associated with higher market demand and $7 million related to the average cost per KWH sold due to higher Southern Company system fuel and purchased power prices, partially offset by a $21 million decrease in non-fuel revenues from wholesale capacity contracts.
The decreases in capacity revenues in the second quarter and year-to-date 2026 were primarily due to the expiration of a power sales agreement in December 2025, partially offset by the commencement of a new power sales

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 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 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 2026, wholesale revenues from sales to affiliates were $55 million compared to $36 million for the corresponding period in 2025. The increase was primarily due to an increase of 73.9% in the volume of KWH sales due to affiliated company energy needs, partially offset by a 10.3% decrease in the price of energy due to a decrease in natural gas prices.
For year-to-date 2026, wholesale revenues from sales to affiliates were $174 million compared to $105 million for the corresponding period in 2025. The increase was primarily due to increases of 49.7% in the volume of KWH sales due to affiliated company energy needs and 11.1% in the price of energy due to an increase in natural gas prices.
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. Energy revenues related to 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.

In the second quarter 2026, wholesale revenues were $120 million compared to $107 million for the corresponding period in 2025. The increase was primarily due to a $15 million increase in energy revenues largely due to increases of $7 million related to the volume of KWH sales associated with higher market demand and $5 million in non-fuel-related energy revenues from wholesale contracts.
For year-to-date 2026, wholesale revenues were $347 million compared to $250 million for the corresponding period in 2025. The increase was due to an $89 million increase in energy revenues due to increases of $44 million related to the average cost per KWH sold due to higher Southern Company system fuel and purchased power prices, $30 million in non-fuel-related energy revenues from wholesale contracts, and $15 million related to the volume of KWH sales associated with higher market demand, as well as an $8 million increase in capacity revenues from new and existing power sales agreements.
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 in 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. Energy revenues related to these transactions do not have a significant impact on earnings since this energy is generally sold at marginal cost.

In the second quarter 2026, wholesale revenues from sales to non-affiliates were $74 million compared to $62 million for the corresponding period in 2025. The increase was primarily due to a $13 million increase associated with new and existing power supply agreements.
For year-to-date 2026, wholesale revenues from sales to non-affiliates were $162 million compared to $133 million for the corresponding period in 2025. The increase was primarily due to a $17 million increase associated with new and existing power supply agreements and an $11 million increase in opportunity sales.
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. Short-term opportunity energy sales are also included in sales for resale to non-affiliates. These opportunity sales are made at market-based rates that generally provide a margin above Mississippi Power's variable cost to produce the energy.

Total operating revenues include PPA capacity revenues derived primarily from long-term contracts associated with natural gas facilities and PPA energy revenues derived from long-term contracts associated with 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 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" in Item 7 of the Form 10-K for additional information regarding Southern Power's PPAs.

Total generation and purchased power (excluding solar, wind, fuel cells, and tolling agreements) | 5.9 | 5.6 | 11.7 | 11.0 | ||||||||||
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.

Southern Company Gas
Southern Company Gas uses Heating Degree Days to measure weather and the operational effects on its business. Generally, increased Heating Degree Days result in higher demand for natural gas on Southern Company Gas' distribution system. However, Southern Company Gas has various regulatory mechanisms, such as weather and revenue normalization and straight-fixed-variable rate design, which limit positive or negative impacts to income from exposure to weather changes within typical ranges in each of its utility's respective service territory. Southern Company Gas also utilizes weather hedges to limit the negative income impacts in the event of warmer-than-normal weather in Illinois and Georgia for gas marketing services. Therefore, weather typically does not have a significant net income impact.
During the Heating Season, more customers are connected to the gas distribution systems and natural gas usage is higher in periods of colder weather. Southern Company Gas' base operating expenses, excluding cost of natural gas and bad debt expense, 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 as a result of seasonality.

Changes in rates resulted in increases in revenues in the second quarter and year-to-date 2026 as compared to the corresponding periods in 2025 primarily due to base rate increases at Nicor Gas and Atlanta Gas Light. 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 2026 as compared to the corresponding period in 2025 primarily due to lower cost of natural gas driven by lower natural gas prices, as well as decreases in other expenses passed through to customers. Revenues associated with gas costs and other cost recovery increased for year-to-date 2026 as compared to the corresponding period in 2025 primarily due to higher cost of natural gas driven by higher natural gas prices in the first quarter 2026, as well as increases in other expenses passed through to customers. See "Cost of Natural Gas" herein for additional information.
Revenues from gas marketing services decreased in the second quarter 2026 as compared to the corresponding period in 2025 primarily due to lower commodity prices. Revenues from gas marketing services increased for year-to-date 2026 as compared to the corresponding period in 2025 primarily due to higher commodity prices in the first quarter 2026, partially offset by weather impacts.

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 87.0% and 84.7% of the total cost of natural gas in the second quarter and year-to-date 2026, respectively. 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" herein for additional information.
In the second quarter 2026, cost of natural gas was $177 million compared to $255 million for the corresponding period in 2025. The decrease reflects lower gas cost recovery as a result of a 15.8% decrease in natural gas prices.
For year-to-date 2026, cost of natural gas was $1.1 billion compared to $0.9 billion for the corresponding period in 2025. The increase reflects higher gas cost recovery, primarily in the first quarter 2026, as a result of an 11.9% increase in natural gas prices.

Gas Distribution Operations
The gas distribution operations segment is the largest component of Southern Company Gas' business and is subject to regulation and oversight by regulatory 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 usage, the earnings of the natural gas distribution utilities can be affected by customer usage patterns that are largely a function of price levels for natural gas and general economic conditions that may impact customers' ability to pay for service. Southern Company Gas has various regulatory and other mechanisms, such as weather and revenue normalization mechanisms, that limit its exposure to changes in customer usage, including weather changes within typical ranges in its natural gas distribution utilities' service territories. See Note 2 to the financial statements under "Southern Company Gas" in Item 8 of the Form 10-K for additional information.
In the second quarter 2026, net income increased $4 million, or 4.4%, when compared to the corresponding period in 2025, as described further below:
•Operating revenues were flat as lower gas cost recovery was offset by base rate increases. Gas costs recovered through natural gas revenues generally equal the amount expensed in cost of natural gas.

•Income taxes increased $16 million primarily as a result of higher pre-tax earnings.
Gas Pipeline Investments
The gas pipeline investments segment consists primarily of joint ventures in natural gas pipeline investments including SNG and Dalton Pipeline. See Note (E) to the Condensed Financial Statements under "Southern Company Gas" herein for additional information.
In the second quarter 2026, net income increased $7 million, or 46.7%, when compared to the corresponding period in 2025. The increase was primarily due to higher revenue from short-term natural gas storage and borrowing services and lower legal expenses, both at SNG.
For year-to-date 2026, net income increased $14 million, or 34.1%, when compared to the corresponding period in 2025. The increase was primarily due to higher revenue from short-term natural gas storage and borrowing services, prior period customer refunds, and lower legal expenses, all at SNG.
Gas Marketing Services
The gas marketing services segment 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.
For year-to-date 2026, net income increased $8 million, or 10.8%, when compared to the corresponding period in 2025. The increase was primarily due to higher retail margins, partially offset by higher operations and maintenance expenses and income taxes.

FUTURE EARNINGS POTENTIAL
Each Registrant's results of operations are not necessarily indicative of its future earnings potential. 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. The Registrants are unable to predict changes in law, regulations, regulatory guidance, legal interpretations, policy positions, and implementation actions that may occur in the future.
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 customer affordability concerns and costs, including those related to projected long-term demand growth, stringent environmental standards, including CCR rules, safety, system reliability and resiliency, fuel, restoration following major storms, and capital expenditures, including constructing new electric generating plants, extending the retirement dates of certain fossil fuel plants, and expanding and improving the transmission and distribution systems; continued customer growth; and the trends of an uncertain inflationary environment and reduced electricity usage per customer, especially in residential and commercial markets.
Earnings in the electricity business will also depend upon maintaining and growing sales and pricing of large customers such that incremental costs are met with adequate incremental revenues, considering, among other things, recent trends driving projected growth in electricity consumption including the increasing digitization of the economy and growth in data centers, an increase in industrial activity in the Southern Company system's electric service territory, and continued electrification of transportation. The traditional electric operating companies enter into large load contracts that support economic development and benefit existing customers.
Since 2023, the traditional electric operating companies have contracts with new data centers and other large load customers covering approximately 11 gigawatts of electric load, with each contract individually representing a maximum electric load greater than 100 MWs, that have been reviewed by the applicable state PSC. Additional contracts totaling approximately five gigawatts of electric load have been agreed with customers and are subject to review by the applicable state PSC. The approximately 16 gigawatts of new contracts (Large Load Contracts) fully ramp up over several years after commencement of service. Some of the Large Load Contracts are currently in effect and have commenced service. Service under the remaining Large Load Contracts is expected to begin through 2028.
All of the Large Load Contracts contain minimum bill provisions. Large Load Contracts totaling approximately 13 gigawatts of electric load (including substantially all signed after 2024) also contain minimum duration, termination payment requirements, and financial security requiring customers to post collateral or provide an acceptable guarantee based on the customer's credit ratings. Certain Large Load Contracts requiring construction of specifically dedicated assets contain provisions for contribution by the customer to construction costs. These terms and conditions are designed to generate adequate incremental revenues associated with incremental costs to serve these customers.
These growth opportunities may be affected by a variety of factors, such as energy efficiency, changes in technology, reliability and operational factors, customer demand, and government policies, which could increase or decrease the associated pace of growth. In addition, these opportunities present risks such as capital access and cost

recovery risks. See Note 2 to the financial statements under "Georgia Power – Integrated Resource Plans" in Item 8 of the Form 10-K for additional information regarding Georgia Power's related regulatory proceedings.
The level of future earnings for Southern Power's competitive wholesale electric business depends on numerous factors including the parameters of the wholesale market and the efficient operation of its wholesale generating assets; Southern Power's ability to execute its growth strategy through the development, construction, or acquisition of generating facilities and other energy projects while containing costs; regulatory matters; customer creditworthiness; total electric generating capacity available in Southern Power's market areas; Southern Power's ability to successfully remarket capacity as current contracts expire; renewable portfolio standards; continued availability of federal and state ITCs and PTCs under current and future tax legislation and U.S. Treasury guidance; transmission constraints; cost of generation from units within the Southern Company power pool; and operational limitations. See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Income Tax Matters" in Item 7 of the Form 10-K for information regarding the IRA's expansion of the availability of federal ITCs and PTCs and the OBBB's restrictions on federal ITCs and PTCs. Also see Note (K) to the Condensed Financial Statements under "Southern Power" herein for information regarding construction projects.
The level of future earnings for Southern Company Gas' primary business of distributing natural gas and its complementary businesses in the gas pipeline investments 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, including those related to projected long-term demand growth, safety, system reliability and resiliency, natural gas, and capital expenditures, including expanding and improving the natural gas distribution systems; the completion and subsequent operation of ongoing infrastructure and other construction projects; customer creditworthiness; and certain policies to limit the use of natural gas, such as the potential in Illinois and across certain other parts of the United States for state or municipal bans on the use of natural gas or policies designed to promote electrification. 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 business to capture value from locational and seasonal spreads. Additionally, changes in commodity prices, primarily driven by tight gas supplies, geopolitical events, and diminished gas production, subject a portion of Southern Company Gas' operations to earnings variability and may result in higher natural gas prices. Additional economic factors may contribute to this environment. The demand for natural gas may increase, including from large customers, which may cause natural gas prices to rise and drive higher volatility in the natural gas markets on a longer-term basis. Alternatively, a significant drop in oil and natural gas prices could lead to a consolidation of natural gas producers or reduced levels of natural gas production.
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; demand growth from data centers and other large load customers and associated load and operating requirements; customer energy conservation practices; the use of alternative energy sources by customers; government incentives to reduce overall energy usage; fuel, labor, and material prices in an environment of heightened inflation and material and labor supply chain disruptions; 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 and could be influenced by changes in technology, public policy, utility efficiency programs, and customer behavior. Geopolitical conflicts (such as the current Middle East conflict) and significant changes in fiscal, monetary, or trade policies could affect actual economic activity and historical economic relationships in ways not anticipated in economic outlooks or Southern Company system plans. Additionally, changes in inflation, interest rates, and credit market conditions could affect the cost of doing business. All of these factors may impact future earnings. See RESULTS OF OPERATIONS herein for information on energy sales in the Southern Company system's service territory during the first six months of 2026.
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,

AND RESULTS OF OPERATIONS (Continued)
partnerships, strategic alliances, joint ventures, and acquisitions involving other utility or non-utility businesses or properties, disposition of, or the sale of interests in, 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/or dispositions of businesses and assets as part of their business strategies. See Note 15 to the financial statements in Item 8 of the Form 10-K, Note (K) to the Condensed Financial Statements herein, and "Construction Programs" herein for additional information.
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.
Environmental Matters
See MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Environmental Matters" and – FINANCIAL CONDITION AND LIQUIDITY – "Cash Requirements" in Item 7 and Note 3 to the financial statements under "Environmental Remediation" and Note 6 to the financial statements in Item 8 of the Form 10-K, as well as Note (C) to the Condensed Financial Statements under "General Litigation Matters" and "Environmental Remediation" herein, for additional information.
Environmental Laws and Regulations
Water Quality
On May 18, 2026, the EPA published the Unmanaged Combustion Residual Leachate (UCRL) proposed rule, which revises the UCRL requirements from the 2024 ELG Rule. The UCRL proposed rule offers a range of regulatory and technology options to address UCRL. The ultimate impacts of this proposed rule cannot be determined at this time; however, a final rule could result in significant compliance costs.
Coal Combustion Residuals
On April 13, 2026, the EPA published a proposed rule that, if finalized, would make several revisions to the existing federal CCR regulations, including rescinding CCR management unit provisions. The proposal also provides additional clarity around the scope of beneficial use and provides for site-specific groundwater, closure, and corrective action flexibilities under federal or state CCR permits.
On July 14, 2026, the EPA proposed the approval of the State of Alabama's partial CCR permit program. If approved, the state's permit program will operate in lieu of the federal CCR program.
The ultimate impact of these actions cannot be determined at this time.
Based on compliance requirements for closure and monitoring of landfills and surface impoundments pursuant to state and federal CCR rules, the traditional electric operating companies have periodically updated, and expect to continue periodically updating, their related cost estimates and ARO liabilities for each CCR unit as additional information related to compliance monitoring, closure methodologies and strategies, schedules, and/or costs becomes available. Some of these updates have been, and future updates may be, material. The cost estimates for Alabama Power are based on closure-in-place for all surface impoundments. The cost estimates for Georgia Power and Mississippi Power are based on a combination of closure-in-place for some surface impoundments and closure by removal for others. 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.

Regulatory Matters
See Note 2 to the financial statements in Item 8 of the Form 10-K, OVERVIEW – "Recent Developments" herein, and Note (B) to the Condensed Financial Statements herein for a discussion of regulatory matters related to Alabama Power, Georgia Power, Mississippi Power, and Southern Company Gas, including items that could impact the applicable Registrants' future earnings, cash flows, and/or financial condition.
Georgia Power
On June 12, 2026, the NRC approved Southern Nuclear's subsequent license renewal application for Plant Hatch Units 1 and 2, renewing both units' operating licenses for an additional 20 years (through 2054 and 2058 for Units 1 and 2, respectively).
Construction Programs
The Southern Company system strategy continues to include developing and constructing new electric generating and battery energy storage facilities, expanding and improving the electric transmission and electric and natural gas distribution systems, and undertaking projects to comply with environmental laws and regulations.
The traditional electric operating companies are engaged in continuous construction programs to accommodate existing and estimated future loads on their respective systems. Major generation construction projects are subject to state PSC approval in order to be included in retail rates, through which the traditional electric operating companies recover their approved investment and a return on investment. See Note 2 to the financial statements under "Georgia Power – Integrated Resource Plans" in Item 8 of the Form 10-K and Note (B) to the Condensed Financial Statements under "Georgia Power – Construction" herein for information regarding Georgia Power's current construction projects.
Southern Power's construction program includes the Millers Branch solar project, the Kay, Grant, Grant Plains, Wake, and Bethel wind repowering projects, and the incremental capacity upgrade projects at the Franklin and Wansley natural gas facilities. The repowering projects result in accelerated depreciation related to the equipment being replaced that will continue until the projects' completion dates, which are projected to occur through the third quarter 2027. At June 30, 2026, the remaining pre-tax accelerated depreciation is projected to total approximately $200 million in 2026 and $100 million in 2027. The ultimate impact of these matters cannot be determined at this time. See Note (K) to the Condensed Financial Statements under "Southern Power" herein and Note 5 to the financial statements under "Depreciation and Amortization – Southern Power" in Item 8 of the Form 10-K for additional information.
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 resiliency, reduce emissions, and meet operational flexibility and growth. The natural gas distribution utilities recover their approved investment and a return on investment associated with these infrastructure programs through their regulated rates, as approved by their applicable state regulatory agency. See Note 2 to the financial statements under "Southern Company Gas – Infrastructure Replacement Programs and Capital Projects" in Item 8 of the Form 10-K for additional information on Southern Company Gas' construction program.
See FINANCIAL CONDITION AND LIQUIDITY – "Cash Requirements" herein for additional information regarding the Registrants' capital requirements for their construction programs.

Income Tax Matters
See Note (G) to the Condensed Financial Statements herein and MANAGEMENT'S DISCUSSION AND ANALYSIS – FUTURE EARNINGS POTENTIAL – "Income Tax Matters" in Item 7 of the Form 10-K for additional information.
Federal Tax Legislation
The OBBB modified certain renewable energy tax incentives and added eligibility restrictions for certain credits related to renewable facilities that are controlled or influenced by, or that receive material assistance from, a prohibited foreign entity.
The U.S. Treasury issued a notice on February 12, 2026, which provides interim safe harbors related to the evaluation of material assistance from a prohibited foreign entity. Southern Company is assessing this guidance and its potential implications for eligibility of technology-neutral tax credits for renewable projects for which construction begins in 2026. The U.S. Treasury has indicated that additional guidance and regulations are expected later in 2026. The ultimate outcome of this matter cannot be determined at this time.
Corporate Alternative Minimum Tax
On February 18, 2026, the U.S. Treasury issued guidance regarding the calculation of the CAMT. The CAMT, enacted as part of the IRA, generally imposes a 15% minimum tax on a corporation's adjusted financial statement income (AFSI) for taxable years beginning after December 31, 2022, subject to applicable thresholds and adjustments under the Internal Revenue Code. The guidance includes provisions that, in certain circumstances, would permit taxpayers to reflect certain repair-related tax deductions as reductions to AFSI for purposes of computing CAMT.
Regulated utilities industry participants have engaged with the U.S. Treasury regarding the interaction of repair-related costs, regulatory accounting, and the CAMT framework. Southern Company is evaluating the guidance, including its applicability to Southern Company's specific facts and circumstances. If applicable, the guidance could reduce Southern Company's potential CAMT exposure by permitting the inclusion of certain repair-related deductions in the computation of AFSI, which could affect Southern Company's income taxes and cash tax position in future periods. Southern Company will continue to assess the impact of the guidance and any further administrative guidance or regulatory developments.
Georgia State Tax Legislation
On May 11, 2026, the State of Georgia enacted tax legislation that reduced the corporate income tax rate from 5.19% to 4.99% effective for the 2026 tax year. This legislation reduced the amount of Southern Company's and certain subsidiaries' income taxes in the State of Georgia and existing state net accumulated deferred tax liabilities and increased regulatory liabilities at Georgia Power and Southern Company Gas. The legislation is not expected to have a material impact on the net income of the applicable Registrants in 2026.
General Litigation and Other Matters
The Registrants are involved in various matters being litigated and/or regulatory and other matters that could affect future earnings, cash flows, and/or financial condition. The ultimate outcome of such pending or potential litigation against each Registrant and any subsidiaries or regulatory and other matters cannot be determined at this time; however, for current proceedings and/or matters 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 and/or matters 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 contingencies, including matters being litigated, regulatory matters, and other matters which may affect future earnings potential.

ACCOUNTING POLICIES
See MANAGEMENT'S DISCUSSION AND ANALYSIS – ACCOUNTING POLICIES in Item 7 of the Form 10-K for a complete discussion of the Registrants' critical accounting policies and estimates, as well as recently issued accounting standards.
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.
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, 2026. 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 "Cash Requirements," "Sources of Capital," and "Financing Activities" herein for additional information.
At the end of the second quarter 2026, the market price of Southern Company's common stock was $95.71 per share (based on the closing price as reported on the NYSE) and the book value was $34.40 per share, representing a market-to-book ratio of 278%, compared to $87.20, $32.18, and 271%, respectively, at the end of 2025. Southern Company's common stock dividend for the second quarter 2026 was $0.76 per share compared to $0.74 per share in the second quarter 2025.
Cash Requirements
See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Cash Requirements" in Item 7 of the Form 10-K for a description of the Registrants' significant cash requirements.
The Registrants' significant cash requirements include estimated capital expenditures associated with their construction programs. 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 or extending the retirement dates of certain generating plants, to meet regulatory requirements; changes in FERC rules and regulations; state regulatory agency approvals; changes in the expected environmental compliance program; changes in legislation, regulation, and/or tariff policy; the cost, availability, and efficiency of construction labor, equipment, and materials; project scope and design changes; abnormal weather; delays in construction due to public or political considerations or judicial or regulatory action; storm impacts; and the cost of capital. In addition, with respect to the traditional electric operating companies and the natural gas distribution utilities, there can be no assurance that any costs related to capital expenditures and AROs will be fully recovered. Additionally, expenditures associated with Southern Power's planned acquisitions may vary due to market opportunities and the execution of its growth strategy.
In the first quarter 2026, Southern Power committed to development projects to upgrade certain turbines at the Franklin and Wansley natural gas facilities. The remaining aggregate construction costs for these projects are expected to be between $580 million and $645 million. See Note (K) to the Condensed Financial Statements under "Southern Power – Natural Gas Turbine Upgrade Projects" herein for additional information regarding Southern Power's construction projects.

Long-term debt maturities and the interest payable on long-term debt each represent a significant cash requirement for the Registrants. See "Financing Activities" herein for information on changes in the Registrants' long-term debt balances since December 31, 2025.
Fuel and purchased power costs represent a significant component of funding ongoing operations for the traditional electric operating companies and Southern Power. Fuel costs include purchases of coal (for the traditional electric operating companies) and natural gas (for the traditional electric operating companies and Southern Power), as well as the related transportation and storage. Since December 31, 2025, Alabama Power and Georgia Power have entered into additional commitments for natural gas primarily related to Alabama Power's conversion of Plant Barry Unit 5 from coal to natural gas and Georgia Power's ongoing construction of generation projects. Total estimated costs for these additional fuel commitments at June 30, 2026 are provided in the table below. See Note (B) to the Condensed Financial Statements under "Georgia Power – Construction" herein and Note 2 to the financial statements under "Alabama Power – Environmental Accounting Order" in Item 8 of the Form 10-K for additional information.

Sources of Capital
See MANAGEMENT'S DISCUSSION AND ANALYSIS – FINANCIAL CONDITION AND LIQUIDITY – "Sources of Capital" in Item 7 of the Form 10-K for additional information. Southern Company intends to meet its future capital needs through operating cash flows, borrowings from financial institutions, and debt, hybrid, and/or equity issuances. Equity capital can be provided from any combination of Southern Company's stock plans, private placements, or public offerings.
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, Alabama Power and Georgia Power plan to utilize borrowings from the FFB. Operating cash flows provide a substantial portion of the Registrants' cash needs. See Note (F) to the Condensed Financial Statements under "DOE Loan Guarantee Borrowings" herein for additional information.
The amount, type, and timing of any financings in 2026, 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 certain of the Subsidiary Registrants), and other factors. See "Cash Requirements" and "Financing Activities" herein for additional information.
By regulation, Nicor Gas is restricted, up to 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, 2026, the amount of subsidiary retained earnings restricted to dividend totaled $2.0 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.
Certain 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

| (in millions) | ||||||||||||||||||||
| Current liabilities in excess of current assets | $ | 3,356 | $ | 1,870 | $ | 109 | $ | 457 | ||||||||||||
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, 2026, unused committed credit arrangements with banks were as follows:

(b)Georgia Power had $26 million of letters of credit outstanding under an uncommitted letter of credit facility at June 30, 2026.
(c)At June 30, 2026, Southern Power also had two continuing letters of credit facilities for standby letters of credit, of which $21 million was unused. In addition, Southern Power Company had $23 million of letters of credit outstanding under an uncommitted letter of credit facility at June 30, 2026. Southern Power's subsidiaries are not parties to its bank credit arrangements or letter of credit facilities.
(d)Includes $798 million and $800 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 certain revenue bonds of the traditional electric operating companies and the commercial paper programs of the Registrants, Nicor Gas, and SEGCO. At June 30, 2026, outstanding variable rate demand revenue bonds of the traditional electric operating companies with allocated liquidity support totaled approximately $1.5 billion (comprised of approximately $796 million at Alabama Power, $667 million at Georgia Power, and $58 million at Mississippi Power). In addition, at June 30, 2026, Georgia Power had approximately $210 million of fixed rate revenue bonds outstanding that are required to be remarketed within the next 12 months. Variable rate demand revenue bonds and fixed rate revenue bonds required to be remarketed within the next 12 months are classified as long-term debt on the balance sheets as a result of available long-term committed credit.
See Note 8 to the financial statements in Item 8 of the Form 10-K and Note (F) to the Condensed Financial Statements under "Bank Credit Arrangements" herein for additional information.
Short-term Borrowings
The Registrants, Nicor Gas, and SEGCO make short-term borrowings primarily through commercial paper programs that have the liquidity support of the committed bank credit arrangements described above.

Credit Rating Risk
At June 30, 2026, the Registrants did 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 contracts that could require collateral, but not accelerated payment, in the event of a credit rating change of certain Registrants to BBB and/or Baa2 or below. These contracts are primarily for physical electricity and natural gas purchases and sales, fuel purchases, fuel transportation and storage, energy price risk management, transmission, interest rate management, and equipment purchases related to construction of facilities.
The maximum potential collateral requirements under these contracts at June 30, 2026 were as follows:
| Credit Ratings | Southern Company(*) | Alabama Power | Georgia Power | Mississippi Power | Southern Power(*) | Southern Company Gas | ||||||||||||||
| (in millions) | ||||||||||||||||||||
| At BBB and/or Baa2 | $ | 32 | $ | 1 | $ | — | $ | — | $ | 31 | $ | — | ||||||||
| At BBB- and/or Baa3 | 459 | 2 | 36 | — | 420 | — | ||||||||||||||
| At BB+ and/or Ba1 or below | 3,723 | 382 | 2,430 | 287 | 1,422 | 32 | ||||||||||||||
(*)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 $106 million of cash collateral posted related to PPA requirements at June 30, 2026.
The amounts in the previous table for the traditional electric operating companies and Southern Power include certain agreements that could require collateral if 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.
