## Modified: The Subsidiary Registrants are subject to workforce factors that could affect operations.

**Key changes:**

- Removed sentence: "The Southern Company system may be subject to continuing workforce trends occurring in the United States triggered by decisions of employees to leave the workforce and/or their employer in higher rates during recent years as compared to prior years and challenges competing with other employers offering more flexible or fully-remote work options."

**Prior (2025):**

The Southern Company system must attract, train, and retain a workforce to meet current and future needs. Events such as an aging workforce without appropriate replacements, increased cost or reduced supply of labor, mismatch of skill sets to future needs, or unavailability of contract resources may lead to operating challenges such as lack of resources, loss of knowledge, and a lengthy time period associated with skill development, including workforce needs associated with construction projects and ongoing operations. The Southern Company system may be subject to continuing workforce trends occurring in the United States triggered by decisions of employees to leave the workforce and/or their employer in higher rates during recent years as compared to prior years and challenges competing with other employers offering more flexible or fully-remote work options. The Southern Company system's costs, including costs for contractors to replace employees, productivity costs, and safety costs, may rise. The Southern Company system is also subject to risks associated with the failure to adequately manage contract resources. In addition, the failure to hire and adequately obtain replacement employees, including the ability to transfer significant internal historical knowledge and expertise to the new employees, or the future availability and cost of contract labor may adversely affect the Southern Company system's ability to manage and operate its business.

## Modified: The Southern Company system may be exposed to regulatory and financial risks related to the impact of GHG legislation, regulation, and emission reduction goals.

**Key changes:**

- Reworded sentence: "Concern and activism about climate change continue and, as a result, demand for energy conservation and sustainable assets could further increase."
- Reworded sentence: "The Southern Company system has processes for identifying, assessing, and responding to climate-related risks, including a scenario planning process that is used to inform resource planning decisions in the states in which the traditional electric I-16 I-16 I-16 Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements operating companies operate."
- Removed sentence: "The SEC adopted new rules relating to the disclosure of climate-related matters, but has stayed their effectiveness pending judicial review."
- Removed sentence: "If these rules, or similar rules, become effective, the Registrants could incur increased costs to comply with these new rules and could face increased risk of litigation related to disclosures made pursuant to the rules."
- Reworded sentence: "For example, beginning in 2024, Nicor Gas' regulator, the Illinois Commission, has conducted "future of natural gas" proceedings to explore the recommendations involved with decarbonization of the gas distribution system in Illinois."

**Prior (2025):**

Concern and activism about climate change continue to increase and, as a result, demand for energy conservation and sustainable assets could further increase. Additionally, costs associated with GHG legislation, regulation, and emission reduction goals could be significant and there is no assurance such costs would be fully recovered through regulated rates or PPAs. The Southern Company system has processes for identifying, assessing, and responding to climate-related risks, including a scenario planning process that is used to inform resource planning decisions in the states in which the traditional electric operating companies operate. This process relies on information and assumptions from internal and external sources, which may or may not be accurate in predicting future outcomes. Additional GHG policies, including legislation, may emerge requiring the United States to accelerate its transition to a lower GHG emitting economy. The ultimate impact will depend on various factors, such as state adoption and implementation of requirements, natural gas prices, the development, deployment, and advancement of relevant energy technologies, the ability to recover costs through existing ratemaking provisions, and the outcome of pending and/or future legal challenges. The SEC adopted new rules relating to the disclosure of climate-related matters, but has stayed their effectiveness pending judicial review. If these rules, or similar rules, become effective, the Registrants could incur increased costs to comply with these new rules and could face increased risk of litigation related to disclosures made pursuant to the rules. Because natural gas is a fossil fuel with lower carbon content relative to other fossil fuels, future carbon constraints, including, but not limited to, the imposition of a carbon tax, may create additional demand for natural gas, both for production of electricity and direct use in homes and businesses. However, such demand may be tempered by legislation limiting the use of natural gas in certain circumstances, including use in new construction and certain household appliances. Additionally, efforts to electrify the transportation, building, and other sectors may result in higher electric demand and negatively impact natural gas demand. For example, throughout 2024 Nicor Gas' regulator, the Illinois Commission, conducted "future of natural gas" proceedings to explore the recommendations involved with decarbonization of the gas distribution system in Illinois. In addition, future GHG constraints, including those related to methane emissions, designed to minimize emissions from natural I-16 I-16 I-16 Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements gas could likewise result in increased costs to the Southern Company system and affect the demand for natural gas as well as the prices charged to customers and the competitive position of natural gas. Southern Company has established an intermediate goal of a 50% reduction in GHG emissions from 2007 levels by 2030 and a long-term goal of net zero GHG emissions by 2050. Achievement of these goals is dependent on various factors, many of which the Southern Company system does not control, including load growth across the Southern Company system's service territory, energy policy and regulations, natural gas prices, and the pace and extent of development and deployment of low- to no-GHG energy technologies and negative carbon concepts. The strategy to achieve these goals also relies on continuing to economically transition the Southern Company system's generating fleet through a diverse portfolio of resources including low-carbon and carbon-free resources; making the necessary related investments in transmission and distribution systems; continuing to implement effective energy efficiency and demand response programs; customer demand for carbon-free energy; implementing initiatives to reduce natural gas distribution emissions; continuing research and development with a focus on technologies that lower GHG emissions, including methods of removing carbon from the atmosphere; and constructively engaging with policymakers, regulators, investors, customers, and other stakeholders to support outcomes leading to a net zero future. There is no guarantee that the Southern Company system will achieve these goals. See MANAGEMENT'S DISCUSSION AND ANALYSIS - FUTURE EARNINGS POTENTIAL - "Environmental Matters - Environmental Laws and Regulations - Greenhouse Gases" in Item 7 herein for additional information.

**Current (2026):**

Concern and activism about climate change continue and, as a result, demand for energy conservation and sustainable assets could further increase. The public holds diverse and often conflicting views on the use of fossil fuels which may subject the Registrants to adverse publicity in connection with their use or supply of fossil fuels. Additionally, costs associated with GHG legislation, regulation, and emission reduction goals could be significant and there is no assurance such costs would be fully recovered through regulated rates or PPAs. The Southern Company system has processes for identifying, assessing, and responding to climate-related risks, including a scenario planning process that is used to inform resource planning decisions in the states in which the traditional electric I-16 I-16 I-16 Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements operating companies operate.

However, such demand may be tempered by legislation limiting the use of natural gas in certain circumstances, including use in new construction and certain household appliances. Additionally, efforts to electrify the transportation, building, and other sectors may result in higher electric demand and negatively impact natural gas demand. For example, beginning in 2024, Nicor Gas' regulator, the Illinois Commission, has conducted "future of natural gas" proceedings to explore the recommendations involved with decarbonization of the gas distribution system in Illinois. The Illinois Commission's final report is expected by the end of 2026. In addition, future GHG constraints, including those related to methane emissions, designed to minimize emissions from natural gas could likewise result in increased costs to the Southern Company system and affect the demand for natural gas as well as the prices charged to customers and the competitive position of natural gas. Since 2018, Southern Company system management established GHG emissions reductions goals including an intermediate goal of 50% from 2007 levels by 2030 and a long-term goal of net zero by 2050. Due primarily to the projected electric load growth, current projections indicate it will be extremely challenging to meet the 2030 goal. Achievement of these goals is dependent on various factors, many of which the Southern Company system does not control, including load growth across the Southern Company system's service territory, including projected load growth from large load customers, energy policy and regulations, natural gas prices, customer demand for carbon-free energy, and the development and deployment of low- to no-GHG energy technologies. The strategy to achieve these goals also relies on continuing to economically transition the Southern Company system's generating fleet through a diverse portfolio of resources including low-carbon and carbon-free resources; making the necessary related investments in transmission and distribution systems; continuing to implement effective energy efficiency and demand response programs; implementing initiatives to reduce natural gas distribution emissions; continuing research and development with a focus on technologies that lower GHG emissions; and constructively engaging with policymakers, regulators, investors, customers, and other stakeholders to support outcomes leading to a net zero future. There is no guarantee that the Southern Company system will achieve these goals.

## Modified: Uncertainty in demand for energy can result in lower earnings or higher costs.

**Key changes:**

- Reworded sentence: "The traditional electric operating companies are experiencing projected demand that significantly exceeds recent experience, creating the need for new power generating resources and transmission facilities."
- Reworded sentence: "Other demands are coming from new industrial facilities with advanced manufacturing processes for products such as electric vehicles and batteries."
- Reworded sentence: "I-26 I-26 I-26 Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements The traditional electric operating companies are currently obligated to supply power to retail customers, as well as wholesale customers under long-term PPAs."
- Reworded sentence: "Because regulators may not permit the traditional electric operating companies to pass all of these purchase or construction costs on to their customers, the traditional electric operating companies may not be able to recover some or all of these costs or may have exposure to regulatory lag associated with the time between the incurrence of costs of purchased or constructed capacity and the traditional electric operating companies' recovery through regulated rates."

**Prior (2025):**

The traditional electric operating companies and Southern Power each engage in a long-term planning process to estimate the optimal mix and timing of new generation assets required to serve future load obligations. Southern Company Gas engages in a long-term planning process to estimate the optimal mix and timing of building new pipelines, replacing existing pipelines, and entering new markets and/or expanding in existing markets. These planning processes must project many years into the future to accommodate the long lead times associated with the permitting and construction of new generation and associated transmission facilities and natural gas distribution facilities. Inherent risk exists in predicting demand as future loads are dependent on many uncertain factors, including economic conditions, customer usage patterns, efficiency programs, and customer technology adoption. The traditional electric operating companies are experiencing projected demand that exceeds recent experience, creating the need for new power generating resources and transmission facilities. The majority of this demand is driven by the power needs and projected power needs of data centers to serve an increasingly digital economy and to support artificial intelligence. Other demands are coming from new industrial facilities with advanced manufacturing processes for such products as electric vehicles and batteries. Ensuring that incremental revenues from these projected new demands cover incremental costs and risks will be critical to continuing the traditional electric operating companies' value proposition to customers. The new nature of these industries, additional capital spending needs, and uncertainties on the actual capacity required to satisfy the projected new demands of these new industries may impact the traditional electric operating companies. Because regulators may not permit the traditional electric operating companies or the natural gas distribution utilities to adjust rates to recover the costs of new generation and associated transmission assets and/or new pipelines and related infrastructure in a timely manner or at all, these subsidiaries may not be able to fully recover these costs or may have exposure to regulatory lag associated with the time between the incurrence of costs and the recovery in regulated rates. In addition, under Southern Power's model of selling capacity and energy at negotiated market-based rates under long-term PPAs, Southern Power might not be able to fully execute its business plan if market prices drop below original forecasts. Southern Power and/or the traditional electric operating companies may not be able to extend or replace existing PPAs upon expiration, or they may be forced to market these assets at prices lower than originally expected. The traditional electric operating companies are currently obligated to supply power to retail customers, as well as wholesale customers under long-term PPAs. Southern Power is currently obligated to supply power to wholesale customers under long-term PPAs. At peak times, the demand for power required to meet obligations could exceed the Southern Company system's available generation capacity. Market or competitive forces may require that the traditional electric operating companies purchase capacity in the open market or build additional generation and transmission facilities and that Southern Power purchase energy or capacity in the open market. Because regulators may not permit the traditional electric operating companies to pass all of these purchase or construction costs on to their customers, the traditional electric operating companies may not be able to recover some or all of these costs or may have exposure to regulatory lag associated with the time between the I-25 I-25 I-25 Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements incurrence of costs of purchased or constructed capacity and the traditional electric operating companies' recovery through regulated rates. Under Southern Power's long-term fixed price PPAs, Southern Power may not be able to recover all of these costs.

**Current (2026):**

The traditional electric operating companies and Southern Power each engage in a long-term planning process to estimate the optimal mix and timing of new generation assets required to serve future load obligations. Southern Company Gas engages in a long-term planning process to estimate the optimal mix and timing of building new pipelines, replacing existing pipelines, and entering new markets and/or expanding in existing markets. These planning processes must project many years into the future to accommodate the long lead times associated with the permitting and construction of new generation and associated transmission facilities and natural gas distribution facilities. Inherent risk exists in predicting demand as future loads are dependent on many uncertain factors, including economic conditions, customer usage patterns, efficiency programs, and customer technology adoption. The traditional electric operating companies are experiencing projected demand that significantly exceeds recent experience, creating the need for new power generating resources and transmission facilities. The majority of this demand is driven by the power needs and projected power needs of data centers to serve an increasingly digital economy and to support artificial intelligence. Other demands are coming from new industrial facilities with advanced manufacturing processes for products such as electric vehicles and batteries. Extending service to these customers necessitates significant capital expenditures, which in turn requires sufficient access to sources of capital. These additional capital spending needs, the increased concentration of business within a single industry based on emerging technologies, and uncertainties on the actual capacity required to satisfy the projected new demands of these new industries creates risks for the traditional electric operating companies. Ensuring that incremental revenues from these projected new demands cover incremental costs and risks is critical to continuing the traditional electric operating companies' value proposition to customers. In particular, Georgia Power has agreed to file its next base rate case in a manner that will ensure the incremental revenue from large load customers has downward pressure, on a levelized basis, of at least $556 million per year for the years 2029, 2030, and 2031. See Note 2 to the financial statements under "Georgia Power - Integrated Resource Plans - Certification Requests" in Item 8 herein for additional information. While electric service agreements with new large load customers (including data centers) typically include provisions such as early termination payments, minimum bills, and financial security, these and other contractual provisions may not fully protect the traditional electric operating companies against all risks. Changes in industry practice or advances in the related technologies could reduce the demand for electricity to power data centers or other large load facilities. Additionally, these industries may experience a business downturn, which could cause the loss of current or potential customers or may weaken the financial condition and creditworthiness of existing customers. If anticipated demand growth does not materialize, the traditional electric operating companies could experience unrecovered capital investments made to serve expected load. Conversely, if demand grows more rapidly than projected, the traditional electric operating companies may face challenges in securing adequate generation and transmission capacity and maintaining service reliability. Because regulators may not permit the traditional electric operating companies or the natural gas distribution utilities to adjust rates to recover the costs of new generation and associated transmission assets and/or new pipelines and related infrastructure in a timely manner or at all, these subsidiaries may not be able to fully recover these costs or may have exposure to regulatory lag associated with the time between the incurrence of costs and the recovery in regulated rates. In addition, under Southern Power's model of selling capacity and energy at negotiated market-based rates under long-term PPAs, Southern Power might not be able to fully execute its business plan if market prices drop below original forecasts. Southern Power and/or the traditional electric operating companies may not be able to extend or replace existing PPAs upon expiration, or they may be forced to market these assets at prices lower than originally expected. I-26 I-26 I-26 Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements The traditional electric operating companies are currently obligated to supply power to retail customers, as well as wholesale customers under long-term PPAs. Southern Power is currently obligated to supply power to wholesale customers under long-term PPAs. At peak times, the demand for power required to meet obligations could exceed the Southern Company system's available generation capacity. Market or competitive forces may require that the traditional electric operating companies purchase capacity in the open market or build additional generation and transmission facilities and that Southern Power purchase energy or capacity in the open market. Because regulators may not permit the traditional electric operating companies to pass all of these purchase or construction costs on to their customers, the traditional electric operating companies may not be able to recover some or all of these costs or may have exposure to regulatory lag associated with the time between the incurrence of costs of purchased or constructed capacity and the traditional electric operating companies' recovery through regulated rates. Under Southern Power's long-term fixed price PPAs, Southern Power may not be able to recover all of these costs.

## Modified: Supply chain disruptions, inflation, elevated interest rates, trade policies (including tariffs and other trade measures), and other economic factors could negatively impact operations.

**Key changes:**

- Reworded sentence: "Future pandemic health events or continued international tensions, including the ramifications of regional or international conflicts, such as those in Ukraine and the Middle East, and any strained relationships between the United States and other countries related to such conflicts, and the impact of trade policies (including tariffs and other trade measures) of the United States and other countries, could further exacerbate global supply chain disruptions."
- Reworded sentence: "Supply chain disruptions and trade policies have contributed to higher prices of components, materials, equipment, and other needed commodities, and these inflationary increases may continue."

**Prior (2025):**

The Southern Company system's operations and business plans depend on the global supply chain to procure equipment, materials, and other resources. The delivery of components, materials, equipment, and other resources that are critical to the Southern Company system's operations has been impacted by domestic and global supply chain disruptions. Future pandemic health events or continued international tensions, including the ramifications of regional conflicts and any strained relationships between the United States and other countries related to such conflicts, such as those in Ukraine and the Middle East, and the impact of tariffs, could further exacerbate global supply chain disruptions. These disruptions and shortages could adversely impact business operations. The constraints in the supply chain also could restrict availability and delay construction, maintenance, or repair of items needed to support normal operations or to continue planned capital investments. Supply chain disruptions have contributed to higher prices of components, materials, equipment, and other needed commodities, and these inflationary increases may continue. Further inflation, a continued elevated interest rate environment, tariffs, or other economic factors may negatively affect operations and the timely recovery of costs.

## Modified: Southern Company and its subsidiaries are subject to substantial federal, state, and local governmental regulation, including with respect to rates. Compliance with current and future legal and regulatory requirements and procurement of necessary approvals, permits, and certificates may result in substantial costs to Southern Company and its subsidiaries. The reduction, elimination, or expiration of government incentives for, or regulations mandating or restricting the use of, renewable energy projects could reduce demand for renewable energy projects and harm the Registrants' businesses.

**Key changes:**

- Reworded sentence: "The traditional electric operating companies, and the power industry in general, have experienced a period of rising costs and projected capital expenditures, especially with respect to infrastructure investments, which is projected to continue for the foreseeable future."
- Reworded sentence: "The current period of rising costs and increased projected capital expenditures could result in increased resistance to authorizing cost recovery."
- Reworded sentence: "Treasury and the IRS."
- Reworded sentence: "The OBBB was signed into law on July 4, 2025."

**Prior (2025):**

Laws and regulations govern the terms and conditions of the services the Southern Company system offers, protection of critical electric infrastructure assets, transmission planning, reliability, pipeline safety, interaction with wholesale markets and retail customers, and relationships with affiliates, among other matters. The Registrants' businesses are subject to regulatory regimes which could result in substantial monetary penalties if a Registrant is found to be noncompliant. The profitability of the traditional electric operating companies' and the natural gas distribution utilities' businesses is largely dependent on their ability, through the rates that they are permitted to charge, to recover their costs and earn a reasonable rate of return on invested capital. The traditional electric operating companies and the natural gas distribution utilities seek to recover their costs, including a reasonable return on invested capital, through their retail rates, which must be approved by the applicable state PSC or other applicable state regulatory agency. Such regulators, in a rate proceeding, may alter the timing or amount of certain costs for which recovery is allowed or modify the current authorized rate of return; rate refunds may also be required. The outcome of any such proceeding could be impacted by a variety of factors, including the level of opposition from intervenors, potential impacts to customers, and past or future changes in the political, regulatory, economic, or legislative environment. See Note 2 to the financial statements under "Southern Company Gas - Infrastructure Replacement Programs and Capital Projects - Nicor Gas" and "Southern Company Gas - Rate Proceedings - Nicor Gas" in Item 8 herein for additional information. Additionally, the rates charged to wholesale customers by the traditional electric operating companies and Southern Power and the rates charged to natural gas transportation customers by Southern Company Gas' pipeline investments must be approved by the FERC. Changes to Southern Power's and the traditional electric operating companies' ability to conduct business pursuant to FERC market-based rate authority could affect wholesale rates. Also, while a small percentage of transmission costs are recovered through wholesale electric tariffs, the majority are recovered through retail rates. Transmission planning and the resulting grid improvements could be impacted by FERC policy changes as well as North American Electric Reliability Corporation planning standard changes. The IRA, among other items, imposes a 15% CAMT on adjusted financial statement income, as defined in the law, and is subject to the issuance of additional guidance by the U.S. Treasury Department and the IRS. Any rate recovery by the traditional electric operating companies or the natural gas distribution utilities subject to the CAMT will be determined pursuant to the regulatory processes of the FERC, state PSCs, or other applicable state regulatory agencies. There is no assurance, however, that such tax will be recoverable through the applicable regulatory process. The Registrants are unable to predict changes in laws or regulations, regulatory guidance, legal interpretations, policy positions, and implementation actions that may result from the change in presidential administrations. The impact of any future revision or changes in interpretations of existing regulations or the adoption of new laws and regulations applicable to Southern Company or any of its subsidiaries is uncertain. Changes in regulation, the imposition of additional regulations, changes in application of existing regulations and in enforcement practices of regulators, as well as associated litigation, or penalties imposed for noncompliance with existing laws or regulations could influence the operating environment of the Southern Company system and may result in substantial costs.

See Note 2 to the financial statements under "Alabama Power" for additional information regarding the Alabama PSC's approval of a plan to keep retail rates stable through 2027, under "Georgia Power - Rate Plans" for additional information regarding the Georgia PSC's approval of a settlement agreement to extend the 2022 ARP through December 31, 2028, with no adjustments to base rates except for storm damage costs incurred through December 31, 2025, and under "Southern Company Gas - Infrastructure Replacement Programs and Capital Projects - Nicor Gas" and " - Rate Proceedings - Nicor Gas" in Item 8 herein for additional information regarding certain disallowances at Nicor Gas. Additionally, the rates charged to wholesale customers by the traditional electric operating companies and Southern Power and the rates charged to natural gas transportation customers by Southern Company Gas' pipeline investments are subject to review by the FERC. Changes to Southern Power's and the traditional electric operating companies' ability to conduct business pursuant to FERC market-based rate authority could affect wholesale rates.

There is no assurance, however, that such tax will be recoverable through the applicable regulatory process. The OBBB was signed into law on July 4, 2025. The OBBB, among other things, materially changed the requirements for most of the federal renewable energy incentives. The Registrants are still assessing the impacts of the OBBB on tax incentives for renewable energy projects. Any loss of, reduction in, or impacts on tax incentives, including transferability of tax credits, due to the OBBB could have a material adverse effect on the Registrants. See MANAGEMENT'S DISCUSSION AND ANALYSIS - I-15 I-15 I-15 Table of Contents Index to Financial Statements Table of Contents Index to Financial Statements FUTURE EARNINGS POTENTIAL - "Income Tax Matters - Federal Tax Legislation" in Item 7 herein for additional information. The Registrants are unable to predict changes in laws or regulations, regulatory guidance, legal interpretations, policy positions, and implementation actions that may occur in the future. The impact of any future revision or changes in interpretations or application of existing laws and regulations or the adoption of new laws and regulations applicable to Southern Company or any of its subsidiaries is uncertain. Changes in laws and regulations, the imposition of additional legal or regulatory requirements, changes in application of existing laws and regulations and in enforcement practices of regulators, as well as associated litigation, or penalties imposed for noncompliance with existing laws or regulations could influence the operating environment of the Southern Company system and may result in substantial costs.
