Letter from our Chairman and Chief Executive Officer

Dear Fellow Stockholders:

**You are invited to attend the Southern Company 2023 Annual Meeting of Stockholders at 10:00 a.m., ET, on Wednesday, May 24, 2023 at The Lodge Conference Center, Callaway Gardens, Pine Mountain, Georgia. We look forward to seeing you in person and discussing Southern Company's 2022 performance.**

------

In January of this year, my successor as President and CEO of Southern Company was announced. I am pleased to share that Chris Womack, my long-time colleague, will succeed me at the conclusion of our annual meeting. I will continue to serve Southern Company as Executive Chairman of the Board of Directors.

The leadership, vision and integrity Chris has demonstrated throughout his career have uniquely prepared him to guide Southern Company into a new era. With the progress at Plant Vogtle and our continued work towards net zero greenhouse gas emissions, the rest of the Board of Directors and I believe now is an ideal time to transition to new leadership. I look forward to working closely with Chris as he assumes his new role and to focusing on an effective transition to my new position as Executive Chairman.

Southern Company experienced another exceptional year in 2022. We reported strong adjusted earnings, reflecting economic strength in our service territories. Both residential customer growth and economic activity outpaced our expectations. We also concluded several major regulatory proceedings at our regulated utilities that foster continued infrastructure investment which is the backbone of our ability to deliver clean, safe, reliable and affordable energy to customers.

Excel at the Fundamentals

We take great pride in the resilience of our systems, and our ability to reliably provide for the energy needs of customers, even under challenging circumstances. In 2022, our operations team, generation fleet and power delivery system performed exceedingly well. This included meeting an all-time peak load of over 41,000 megawatts in June, and a winter peak of nearly 38,000 megawatts as frigid temperatures over the Christmas weekend resulted in a record December demand for electricity in our service footprint.

Achieve Success with Major Construction Projects

Last year saw significant progress at Plant Vogtle Units 3 and 4. All 157 fuel assemblies were loaded to the Unit 3 reactor core in October, and the site team has turned to the testing and start-up process. Cold hydro testing for Unit 4 was completed in December and hot functional testing began this March. Component and system testing activities are steadily increasing in support of eventual fuel load at Unit 4. Once completed, these units are expected to be reliable sources of carbon-free energy for the next 60 to 80 years. Moreover, once these two new units are in

service and operating alongside the two existing units, Plant Vogtle will be the largest producer of carbon-free energy in the United States.

Value and Develop Our People

Our commitment to employees is reflected in numerous accolades. We were the top-rated utility in *Military Times'* Best for Vets Employers, and we were recently named the number one utility in *Forbes'* 2023 ranking of America's Best Large Employers, nearly 100 spots above our closest industry peer.

For the seventh consecutive year, we have been recognized as one of the Top 50 Companies for Diversity by Diversitylnc. Some 81% of system employees participated in diversity, equity and inclusion development in 2022. Across the enterprise, employee resources groups, councils and networks bring employees together to cultivate inclusion and a healthy work environment.

As Chris Womack takes the reins as President and CEO, I have never been more enthusiastic about the future. And even as a new generation of leaders emerges and we move boldly forward with new innovations, we remain committed to the ideals that have characterized our company for more than 100 years. Customers remain at the center of all we do, and our mission continues to be bigger than our bottom line.

We hope you can join us in person at the annual meeting. A live webcast of the annual meeting will be available at *investor.southerncompany.com* starting at 10:00 a.m., ET, on Wednesday, May 24, 2023. A replay will be available following the meeting.

**Your vote is important.** We urge you to vote as soon as possible by internet or by telephone or, if you received a paper copy of the proxy form by mail, by signing and returning the proxy form.

It has been my privilege to serve this great company and its stockholders. Thank you for your continued confidence in Southern Company.

Letter from our Independent Directors

Dear Fellow Stockholders:

**As independent Directors, we strive to govern Southern Company in a prudent and transparent manner with a commitment to sound governance principles. We thank you for the trust you place in us.**

------

CEO Succession and Board Leadership Structure

One of our most important responsibilities as Directors is selecting the best leader for our Company and planning and executing a smooth CEO transition. Our thoughtful planning process resulted in the unanimous decision that Chris Womack will succeed Tom Fanning as CEO effective immediately after the annual meeting. Mr. Womack also became President and joined the Board effective March 31, 2023. We believe Mr. Womack's proven leadership, alignment with our values and ability to deliver strong results makes him a terrific choice to lead Southern Company into the future. Mr. Womack brings to the Board 35 years of experience within our business and industry, including leadership experience as CEO of Georgia Power, governmental affairs and regulatory experience, power delivery experience, human resources experience and a deep understanding of the customers and communities we are privileged to serve.

We also review our board leadership structure on an annual basis. As part of the CEO succession planning process, we evaluated our current leadership structure and the leadership structure that would best serve stockholders at the time of the CEO transition. We unanimously concluded that our Company will be best served by a leadership structure consisting of Mr. Fanning, our retiring CEO, serving as Executive Chairman, Mr. Womack serving as CEO and Director, and a Lead Independent Director appointed by the Board's independent members, with each role having clearly delineated responsibilities.

Oversight of Strategy

The energy industry is changing, driven by the advent of new technologies as well as an emphasis on decarbonization by customers, investors and other stakeholders. We have seen an increasing focus by stakeholders on reliability, resiliency and affordability. Southern Company's objective is to develop durable business strategies that help customers and communities shift to a new energy economy through an orderly transition that preserves reliability, resiliency and affordability, while also reducing emissions.

Another important responsibility of our Board is overseeing Southern Company's strategy of maximizing long-term value to stockholders through a customer-focused business model that prioritizes the provision of clean, safe,

reliable and affordable energy. At each Board meeting and during our regular strategy sessions, we contribute to management's strategic plan by engaging senior leadership in robust discussions about overall strategy, business priorities, long-term risks and growth opportunities.

A key element of Southern Company's decarbonization strategy is the construction of Plant Vogtle Units 3 and 4. Once complete, these units are expected to serve customers with carbon-free electricity for the next 60 to 80 years. While the Company made significant progress on the units in 2022, it also faced challenges leading to additional delays and cost increases. We remain focused on our oversight of the project and look forward to the units coming online.

In 2022, the Company made significant progress toward its net zero by 2050 goal by retiring more than 900 MW of coal-fired generation and completing the conversion of a coal-fired unit to natural gas. Importantly, we received regulatory approval to retire or convert additional units and increase our owned and contracted renewables and energy storage resources in future years. The Board continues to work closely with management on planning and transitioning the system, with focus given to capital allocation for replacement capacity and grid enhancements, community and employee impacts and advocacy for policies to help mitigate cost and societal impacts of the transition.

Board Composition and Governance

Board refreshment, Board diversity and meaningful Board succession planning are top of mind for our Board. We believe in the business value of having diverse perspectives in the boardroom, and we are deliberate in ensuring we have the right mix of perspectives, skills and expertise to address the Company's current and future needs. Since January 2019, we have added seven new Directors to our Board, including three Directors since the beginning of this year.

In addition to Mr. Womack, we recently welcomed David Meador and Lizanne Thomas to our Board. Mr. Meador brings public energy company experience and expertise in the energy sector, including financial, information technology, manufacturing, procurement, and corporate and public affairs proficiency, as well as experience in economic and workforce development. Ms. Thomas brings mergers and public and private acquisitions expertise

as well as corporate governance experience. Her legal background and extensive governance work with publicly traded companies spans a wide spectrum of industries. The addition of these three directors further strengthens our Board's diversity and its mix of skills, experiences and perspectives.

We are dedicated to the effective oversight of the Company's business and the key risks the Company faces. We fulfill our oversight responsibilities through our six standing committees and as a full Board. Each committee provides ongoing oversight for the most significant issues and risks designated to it, reports to the Board on its oversight activities and elevates review of key matters to the Board as appropriate. We continually assess committee structures and responsibilities to help ensure alignment with existing and emerging focus areas for our Company and industry.

Diversity, Equity and Inclusion

We recognize that Southern Company's talent is one of its greatest strengths, and the Company has a strong track record of employee engagement and retention. Workforce sustainability topics, including DE&I, are regularly discussed by the Board and its committees. As we think longer-term, we believe that a diverse, equitable and inclusive corporate culture brings broader perspectives, greater innovation, richer thinking and wider cultural bandwidth.

We also recognize the importance of racial equity and inclusion within the communities Southern Company serves, and the Company's Moving to Equity initiative is regularly discussed by the Board and its committees. At a time of transformation in our industry, we believe that companies with a clear sense of purpose combined with a culture that embraces change, engages in healthy debate and encourages innovation will be the most adaptable.

Stakeholder Engagement

We maintain our focus on understanding and responding to the viewpoints of our investors and other stakeholders. We support management's efforts to engage with a broad set of stakeholders and its recent enhancements to the Company's ESG disclosures in response to stakeholder interest. On behalf of the Board, independent Directors also remain committed to engagement with our largest stockholders. In 2022 and early 2023, independent Directors directly engaged (without the CEO present) with stockholders representing over 20% of our outstanding shares.

Thank you for the trust you place in us. By helping management address near-term priorities and challenges while maintaining a long-term outlook, we are best able to support our common goal of creating enduring long-term value for customers, employees and stockholders alike. We are grateful for the opportunity to serve Southern Company on your behalf.

Our 2022 Performance

Our goal is to deliver long-term value to stockholders with appropriate risk-adjusted total shareholder return (TSR). During 2022, we maintained our track record of strong reliability and customer service, Georgia Power made meaningful progress at Plant Vogtle Units 3 and 4, we achieved constructive regulatory outcomes across several subsidiaries and we executed our financial plan. Underpinning these successes is our commitment to excel at the fundamentals, which includes prioritizing customers and communities as well as focusing on the well-being of our employees.

---

► We reported adjusted
 EPS at the top end of our guidance range for 2022. Our strong adjusted earnings were driven by rates and pricing at our regulated
 utilities, warmer weather, customer growth and increased usage. In addition, we achieved constructive regulatory outcomes.

► We increased our dividend for the
 21st consecutive year, with a 3.8% dividend yield as of year-end 2022.

► We continued to focus on our regulated
 businesses by divesting of non-core assets such as the Golden Triangle Storage facility.

► We effectively executed our capital
 plan and maintained discipline around our credit metrics.

► We continued to economically transition
 our generating fleet to lower GHG emitting fuel sources and focused on opportunities to reduce emissions across the energy
 value chain.

| ![](so4109301-pre14ax11x1.jpg) | Demonstrated Progress Toward our Net Zero by 2050 Goal |

---

**Our strategy includes the continued development of a diverse portfolio of energy resources to serve customers and communities reliably and affordably with a focus on reducing GHG emissions.**

► We continue to make
 progress toward our interim goal of reducing GHG emissions by 50% from 2007 levels by 2030, as we move forward to our long-term
 goal of net zero by 2050. We reported that 2022 emissions were 46% below 2007 levels, and we expect to consistently achieve
 GHG reductions of greater than 50% as early as 2025, a full five years earlier than our interim goal.

► In 2022, we retired 933 MWs of coal-fired
 generation and completed the conversion of a 362 MW coal-fired unit to natural gas, and received regulatory approval to retire
 or convert additional units in future years. Pending regulatory approval, we expect to have only eight to ten coal units remaining
 by the end of 2028, down from 66 in 2007, with further reductions expected by 2035.

► We received regulatory approval
 to increase our owned and contracted renewables and energy storage resources to approximately 17,400 MW in 2030 from 11,500
 MW in 2022.

► The work of planning, transitioning
 and operating our system to meet our decarbonization goals will require continued active and constructive engagement with
 government officials, investors and a wide variety of other public and private stakeholders. Our success will require the
 support of policies that encourage and advance innovation while protecting the reliability, resiliency and affordability of
 the services we provide to our customers.

► We continue to enhance our reporting
 on ESG topics, including climate-related disclosure aligned with the Task Force on Climate-Related Financial Disclosures (TCFD)
 recommendations. In 2022, we obtained third-party limited assurance on our Scope 1 and 2 GHG emissions for the years 2020
 and 2021, as well as for our baseline year 2007. We also expanded our GHG emissions reporting to include all relevant Scope
 3 emissions. Southern Company earned a score of A- for its CDP Climate Change Disclosure for the third consecutive year, demonstrating
 leadership for the North American region and thermal power generation sector. We also published reports responsive to stakeholder
 interests outlining our Just Transition principles and our approach to climate engagement with policymakers.

| Our Decarbonization Efforts<br> Southern Company is committed to providing clean, safe, reliable and affordable energy, with a focus on reducing GHG emissions. Since 2007, coal-generated energy as a percentage of our energy mix has declined from 69% to 20%, and energy generated from carbon-free sources has more than doubled. | Our Decarbonization Efforts<br> Southern Company is committed to providing clean, safe, reliable and affordable energy, with a focus on reducing GHG emissions.

| **ANNUAL ENERGY MIX**<br> ![](so4109301-pre14ax11x2.jpg) | ► Annual energy mix represents all of the energy the Southern Company system uses to serve its retail and wholesale customers during the year. It is not meant to represent delivered energy mix to any particular retail customer or class of customers. Annual energy mix percentages include non-affiliate power purchase agreements.<br> ► Renewables/Other category includes wind, solar, hydro, biomass, landfill gas and fuel cells.<br> ► With respect to certain renewable generation and associated renewable energy credits (RECs), to the extent an affiliate of Southern has the right to the RECs associated with renewable energy it generates or purchases, it retains the right to sell the energy and RECs, either bundled or separately, to retail customers and third parties.<br> ► Electric demand in 2020 was reduced by COVID-19 impacts and mild weather. Low natural gas prices in 2020 gave the natural gas generating fleet favorable economics relative to most coal units, displacing additional coal generation. |

---

► From inflationary pressures
 and tight labor markets to the lingering effects of the COVID-19 pandemic, throughout 2022 many of our employees have experienced
 personal challenges related to their physical, financial and emotional well-being. The Company continues to invest in comprehensive
 benefit plans, programs and policies that help stabilize and improve the well-being of our employees and their families. We
 have seen engagement in these resources expand and their impacts multiply as employees redefine and rediscover their well-being
 in a post-pandemic world.

► We enhanced training and workforce
 development opportunities to support employees at all levels and foster retention in an increasingly competitive landscape.

► In 2022, we expanded our efforts
 to recruit, develop and retain diverse talent. The Company increased its recruiting partnerships with historically Black colleges
 and universities (HBCUs) as well as other diverse talent segments including Asian, Hispanic, women and veterans.

**Our GHG Reduction Goals**

We have set an interim goal to reduce system-wide Scope 1 GHG emissions by 50% by 2030 (from 2007 levels) and a long-term goal of net zero emissions by 2050. In 2022, we achieved a 46% reduction in GHG emissions relative to 2007 levels, a slight decrease from our 47% reduction for 2021 due to increased generation associated with higher electricity sales. We expect to sustainably reach our 50% reduction goal as early as 2025.

We believe our path to net zero will be achieved through:

---

| | | |
|:---|:---|:---|
| ► Continued coal transition<br> ► Utilization of natural gas to enable fleet transition | ► Further growth in portfolio of zero-carbon resources<br> ► Negative carbon solutions | ► Enhanced energy efficiency initiatives<br> ► Continued investment in R&D focused on clean energy technologies |

![](so4109301-pre14ax13x1.jpg)

During 2022, we retired 933 MWs of coal-fired generation, completed the conversion of a 362 MW coal-fired unit to natural gas and received regulatory approval to retire or convert additional units in future years. By the end of 2028, pending additional future regulatory approvals, we expect to have only eight to ten coal units remaining, down from 66 in 2007, with further reductions anticipated by 2035.

In addition to our efforts to reduce direct Scope 1 emissions, we are working across the Southern Company system to reduce indirect Scope 3 emissions across the value chain.

**Empowering our workforce**

Our nation faced a global health pandemic, an economic downturn and social and political unrest over the past several years. These events have placed ongoing mental, physical and financial burdens on many of our employees. We continue to keep employees informed and updated about issues facing the Company and the community with focused efforts on:

● Increasing sourcing and outreach for underrepresented talent

● Conducting campus, military and executive searches

● Direct sourcing, outreach with community and diverse associations and targeted advertising

● Partnering with organizations whose missions are aligned with advancing DE&I

![](so4109301-pre14ax19x1.jpg)

Proxy Voting Roadmap

**ITEM 1** Election of 16 Directors

► The Board, acting upon the recommendation
 of the Nominating, Governance and Corporate Responsibility Committee, has nominated the 16 Directors currently serving for re-election
 to the Southern Company Board of Directors.

► Each nominee holds or has held senior executive positions,
 maintains the highest degree of integrity and ethical standards and complements the needs of the Company and the Board.

► Through their positions, responsibilities, skills and
 perspectives, which span various industries and organizations, these nominees represent a Board of Directors that is diverse and
 possesses appropriate collective qualifications, skills, knowledge and experience.

---

| | | |
|:---|:---|:---|
| ![](so4109301-pre14ax19x2.jpg) | The Board recommends a vote **FOR** each nominee for Director | ►&nbsp;&nbsp;&nbsp;&nbsp;See page 19 |

---

**ITEM 2** Advisory Vote to Approve Executive Compensation (Say on Pay)

► We believe our compensation program
 provides the appropriate mix of fixed and at-risk compensation.

► The short- and long-term performance-based compensation
 program ties executive pay to Company performance, rewards achievement of financial and operational goals, relative TSR and progress
 on meeting our GHG reduction goals (for our CEO, CFO and EVP of Operations), encourages individual performance that is in line with
 our long-term strategy, is aligned with stockholder interests and remains competitive with our industry peers.

|:---|:---|:---|
| ![](so4109301-pre14ax19x2.jpg) | The Board recommends a vote **FOR** this proposal | ►&nbsp;&nbsp;&nbsp;&nbsp;See page 56 |

---

**ITEM 3** Advisory Vote to Approve Frequency of Future Advisory Votes on Executive Compensation (Say on Frequency)

► Shareholders are being provided
 the opportunity to vote on the frequency of the advisory vote to approve executive compensation (Say on Frequency), which is required
 at least once every six years. The frequency options are to hold the advisory vote every one, two or three years. In both 2011 and
 2017, the Board recommended and the stockholders voted overwhelmingly in favor of holding the Say on Pay vote every year. The Board
 continues to believe that the Say on Pay vote should be held every year.

**Proxy Voting Roadmap**

**ITEM 5** Approve an Amendment to the Restated Certificate of Incorporation to Reduce the Supermajority Vote Requirement to a Majority Vote

► A supermajority vote requirement
 like the one contained in Article Eleventh of the Restated Certificate of Incorporation (Certificate of Incorporation or Certificate)
 historically has been intended to facilitate corporate governance stability and provide protection against self-interested action
 by large stockholders by requiring broad stockholder consensus to make certain fundamental changes.

► As corporate governance standards have evolved, many
 stockholders and commentators now view a supermajority requirement as limiting the Board's accountability to stockholders and
 the ability of stockholders to effectively participate in corporate governance.

**CEO Succession Process**

In January, we announced that the Board selected Mr. Womack to succeed Mr. Fanning as President and CEO of Southern Company. Mr. Womack was appointed President and elected as a member of the Board effective March 31, 2023. He will assume the role of CEO immediately following the conclusion of the annual meeting. Mr. Fanning relinquished the role of President effective March 31, 2023 and will assume the role of Executive Chairman of the Board of Directors upon Mr. Womack's assumption of the role of CEO.

As part of its ordinary course responsibilities, the Board regularly and actively engages in management succession planning. In 2021, the Board decided to augment its existing succession planning process with an additional, more formal structure to facilitate the CEO succession decision and help ensure a smooth leadership transition.

**Succession Committee of the Board**

In July 2021, the Board established an ad hoc committee of the Board, the Succession Committee, to lead the CEO succession process on behalf of the Board. The Succession Committee met six times from July 2021 through December 2022.

**Corporate Governance at Southern Company**

The Succession Committee was comprised of four independent directors: Mr. Grain, the Lead Independent Director, Mr. Johns, the Chair of the Compensation and Talent Development Committee, Mr. Earley, the Chair of the Nominating, Governance and Corporate Responsibility Committee, and Juanita Powell Baranco, an independent Director who retired at the 2022 annual meeting. Mr. Grain served as Chair of the Succession Committee.

Given the desire to continue to leverage Ms. Baranco's knowledge and expertise, we entered into a consulting agreement with Ms. Baranco on June 9, 2022, after her retirement from the Board, for the provision of professional consulting services and advice to the Company and the Board regarding CEO succession planning. The amount paid to Ms. Baranco for 2022 is included in the Director Compensation Table on page 54. After her retirement from the Board, Ms. Baranco continued to attend meetings of the Succession Committee in an advisory, non-voting capacity.

The Succession Committee considered a number of items as part of its robust evaluation process

► Identified key skills and expertise desired in a CEO candidate

► Identified potential internal candidates

► Identified potential external candidates

► Conducted extensive interviews with key candidates

► Evaluated input from an external leadership advisory consulting firm, including detailed feedback and 360° assessments they had compiled

In addition to interviews with the Succession Committee, key candidates met with all independent members of the Board. The Board and Succession Committee also continued to gain access and exposure to the key candidates through regular Board and committee meetings.

The Succession Committee reported out to the independent Directors and led discussions with the independent Directors during the Board's executive sessions held at every regular Board meeting from July 2021 through December 2022. Mr. Fanning provided input to the Succession Committee on his evaluation of the CEO candidates, but he did not participate in the Succession Committee meetings or the executive sessions of the Board.

As part of the succession planning process, the Succession Committee also evaluated candidates for key leadership roles across the system. In January, the Board announced new leaders of several of our key subsidiaries as part of the Company's succession and management transition plan.

► Kimberly S. Greene was named Chair of the Board of Directors, CEO and President of Georgia Power

► J. Jeffrey Peoples was named Chairman of the Board of Directors, CEO and President of Alabama Power

► James Y. Kerr II was named Chairman of the Board of Directors, CEO and President of Southern Company Gas

The Succession Committee also worked with the Nominating, Governance and Corporate Responsibility Committee to determine the appropriate Board leadership structure for Southern Company at the time of the CEO transition. See page 44 for a discussion of the comprehensive review undertaken to determine the Board's future leadership structure.

**Engaging with our Stakeholders**

We place great importance on consistent dialogue with all our stakeholders, including stockholders, employees, customers and members of the communities that we serve. We regularly engage in discussions with, and provide comprehensive information for, constituents interested in Southern Company's strategy, performance, governance, citizenship, stewardship and environmental compliance. We are receptive to stakeholder input, and we are committed to transparency and proactive interactions.

In addition, our CFO and investor relations group lead our management team in hundreds of investor meetings throughout the year to discuss our business, strategy and financial results. Increasingly, these discussions also include ESG-related topics. Meetings include in-person, telephone and webcast conferences.

**Environmental Stakeholder Engagement**

Since 2011, we have held regular environmental stakeholder forums, webinars, calls and meetings covering a range of topics, including our efforts to reduce GHG emissions, regulatory and policy issues, system risk and planning related to renewables, energy efficiency, just transition and environmental justice. Members of senior management participate in these events.

In May 2022, we hosted a hybrid environmental stakeholder forum in Washington D.C. Tom Fanning, our CEO, led discussions with stakeholders. Other senior leaders that participated included the Chief Financial Officer, Chief Legal Officer, EVP of Operations and SVP of Environment, System Planning and Sustainability. Key topics discussed included our net zero by 2050 goal, decarbonization efforts, R&D, enhancing affordability in the fleet transition, electric vehicles and just transition. More than 20 stakeholders participated in the forum, some in-person and others virtually. Stakeholder participants include regional environmental and socially focused non-governmental organizations, shareholder advocacy groups and state pension funds. We also invited the co-lead investors of the Climate Action 100+ investor initiative to participate.

"It's important to us to organize the environmental stakeholder forum because it helps to foster constructive dialogue and durable relationships of trust between us and our stakeholders. We get to hear about our stakeholders' concerns and they get a better understanding of the things we're working on."

– Tom Fanning, Chairman and CEO

In October 2022, we hosted approximately 20 stakeholders, including members of the Climate Action 100+ initiative, in Birmingham, Alabama where we toured our energy trading floor, the solar array near Alabama Power's Smart Neighborhood and the National Carbon Capture Center.

In November 2022, we held a virtual stakeholder dialogue focused on natural gas with speakers from Southern Company Gas and several of our NGO stakeholders. Topics included methane emissions reductions, gas demand reductions and decarbonizing the natural gas supply.

We had several follow-up conversations with participants in the stakeholder forums to further discuss topics raised at the meetings.

**Corporate Governance at Southern Company**

**Board Composition and Structure**

**Board Diversity, Board Refreshment and Board Succession Planning**

Our commitment to diversity, equity and inclusion begins with the Board. Our Board believes a diverse variety of viewpoints contribute to a more effective decision-making process and helps drive long-term value.

While our Corporate Governance Guidelines do not prescribe diversity standards, the Guidelines provide that the Board as a whole should be diverse. The Guidelines also include "Rooney Rule" language confirming the Board's commitment to actively seeking out women and minority candidates to include in the pool from which Board nominees are chosen. The Nominating, Governance and Corporate Responsibility Committee assesses the effectiveness of its efforts at pursuing diversity through its regular evaluations of the Board's composition.

The Nominating, Governance and Corporate Responsibility Committee continues to focus on Board refreshment to align the Board's long-term composition with the Company's long-term strategy and to effect meaningful Board succession planning. It has an evergreen Board search process in place and has retained a nationally-recognized Board search firm to assist in the identification of qualified candidates.

► The Nominating, Governance and Corporate Responsibility Committee regularly evaluates the expertise and needs of the Board to determine the Board's membership and size.

► As part of this evaluation, the Nominating, Governance and Corporate Responsibility Committee considers aspects of diversity, such as diversity of race, gender and ethnicity.

► The Nominating, Governance and Corporate Responsibility Committee also considers diversity of age, education, industry, business background and experience in the selection of candidates to serve on the Board.

Since January 2019, we have added seven new Directors to the Board.

The Board aims to strike a balance between the knowledge that comes from longer-term service on the Board and the new experience and ideas that can come from adding Directors to the Board. The Board believes the average tenure of the 16 Director nominees of approximately 7.5 years reflects the balance the Board seeks between different perspectives brought by longer-serving Directors and new Directors.

The Board aims to continue to refresh its membership over time.

Stockholder Recommendation of Board Candidates

► The Nominating, Governance and Corporate Responsibility Committee considers potential board candidates recommended by stockholders.

► Recommendations can be made by submitting the candidate's information to our Corporate Secretary in writing at Southern Company, 30 Ivan Allen Jr. Boulevard NW, Atlanta, Georgia 30308. Stockholders should provide as much relevant information about the candidate as possible, including the candidate's biographical information and qualifications to serve.

► A stockholder recommended candidate is reviewed in the same manner as a candidate identified by the Nominating, Governance and Corporate Responsibility Committee.

► For information about the direct nomination of directors for election by stockholders at an annual meeting as provided in the By-Laws, see page 123 .

**Service on Other Boards and Committees**

In identifying candidates to serve on the Board and in evaluating whether to recommend the re-election of existing Directors, the Nominating, Governance and Corporate Responsibility Committee considers whether a candidate or a Director demonstrates a willingness to commit sufficient time to serving on the Board. The Nominating, Governance and Corporate Responsibility Committee is regularly updated on the public company board service limit or "overboarding" policies of our largest stockholders.

Our Corporate Governance Guidelines include limitations on the number of public company boards and public company audit committees a Director may serve.

► No employed Director may serve on more than two public company boards (not including the Company's Board or the director's employing company board) unless otherwise approved by the Nominating, Governance and Corporate Responsibility Committee.

► No Director may serve on more than four public company boards (including the Company's Board), unless otherwise approved by the Nominating, Governance and Corporate Responsibility Committee.

► No Director who is a member of the Company's Audit Committee may serve on the audit committees of more than three public companies (including the Company's Audit Committee).

In addition to these limitations, our Corporate Governance Guidelines require that the Company's CEO will not serve on other public company boards without consulting with the Board. They also require that current Directors must notify the CEO and the Chair of the Nominating, Governance and Corporate Responsibility Committee when considering a request for service on another public company board.

Each of the Directors are in full compliance with these Corporate Governance Guidelines.

As part of its annual evaluation on whether to recommend the re-election of existing Directors, the Nominating, Governance and Corporate Responsibility Committee is provided information on the public company boards and private company for-profit boards on which each Director serves, as well as the Directors' attendance records at Southern's Board and committee meetings. In 2022, all our Directors attended at least 75% of applicable Board and committee meetings, with the average Director attendance at all applicable Board and committee meetings at 98%. These factors also influence the Nominating, Governance and Corporate Responsibility Committee's annual consideration of Board leaderships positions, committee leadership positions, and committee membership.

**Corporate Governance at Southern Company**

**Majority Voting For Directors and Director Resignation Policy**

We have a majority vote standard for Director elections, which requires that a nominee for Director in an uncontested election receive a majority of the votes cast at a stockholder meeting in order to be elected to the Board. The Board believes that the majority vote standard in uncontested Director elections strengthens the Director nomination process and enhances Director accountability.

We also have a Director resignation policy, which requires any nominee for election as a Director to submit an irrevocable letter of resignation as a condition to being named as such nominee, which would be tendered in the event that nominee fails to receive the affirmative vote of a majority of the votes cast in an uncontested election at a meeting of stockholders. Such resignation would be considered by the Board, and the Board would be required to either accept or reject such resignation within 90 days from the certification of the election results.

**Board Independence**

Director Independence Standards

No Director will be deemed to be independent unless the Board affirmatively determines that the Director has no material relationship with the Company directly or as an officer, stockholder or partner of an organization that has a relationship with the Company. The Board has adopted categorical guidelines which provide that a Director will not be deemed to be independent if within the preceding three years:

► The Director was employed
 by the Company or the Director's immediate family member was an executive officer of the Company.

► The Director has received, or the Director's
 immediate family member has received, during any 12-month period, direct compensation from the Company of more than $120,000,
 other than Director and committee fees. (Compensation received by an immediate family member for service as a non-executive
 employee of the Company need not be considered.)

► The Director was affiliated with or employed
 by, or the Director's immediate family member was affiliated with or employed in a professional capacity by, a present
 or former external auditor of the Company and personally worked on the Company's audit.

► The Director was employed, or the Director's
 immediate family member was employed, as an executive officer of a company where any of the Company's present executive
 officers at the same time served on that company's compensation committee.

► The Director is a current employee, or the Director's
 immediate family member is a current executive officer, of a company that has made payments to, or received payments from,
 the Company for property or services in an amount which, in any year, exceeds the greater of $1,000,000 or 2% of that company's
 consolidated gross revenues.

► The Director or the Director's spouse
 serves as an executive officer of a charitable organization to which the Company made discretionary contributions which, in
 any year, exceeds the greater of $1,000,000 or 2% of the organization's consolidated gross revenues.

These guidelines are in compliance with the NYSE corporate governance rules within its listing standards.

Director Independence Review Process

At least annually, the Board receives a report on all commercial, consulting, legal, accounting, charitable or other business relationships that a Director or the Director's immediate family members have with the Company and its subsidiaries. This report includes all ordinary course transactions with entities with which the Directors are associated.

► The Board determined that
 the Company and its subsidiaries followed our procurement policies and procedures and our policy relating to the approval
 and ratification of related person transactions, that the amounts reported were well under the thresholds contained in the
 Director independence requirements and that no Director had a direct or indirect material interest in the transactions included
 in the report.

► The Board reviewed all contributions made by
 the Company and its subsidiaries to charitable organizations with which the Directors are associated. The Board determined
 that the contributions were consistent with other contributions by the Company and its subsidiaries to charitable organizations
 and none were approved outside the Company's normal procedures.

► In determining Director independence, the Board
 considers transactions, if any, identified in the report discussed above that affect Director independence, including any
 transactions in which the amounts reported were above the threshold

| contained in the Director independence requirements and in which a Director had a direct or indirect material interest. No such transactions were identified and, as a result, no such transactions were considered by the Board. |
| In making its determination, the Board considered the fact that one of the Company's Directors, Lizanne Thomas, was a partner at Jones Day until December 31, 2022, when she became Of Counsel. Jones Day provides legal services to the Company and its affiliates. The Board noted that in 2022 and prior, Ms. Thomas' compensation from Jones Day was unaffected by the amount of legal services performed for us by Jones Day and that Ms. Thomas no longer provides legal services to us. Jones Day has not received payments from us over the past three years that exceeded 1% of its annual revenues. |
| The Board also considered that, in the ordinary course of the Southern Company system's business, electricity and natural gas are provided to some Directors and entities with which the Directors are associated on the same terms and conditions as provided to other customers of the Southern Company system. |

---

**As a result of its review process, the Board affirmatively determined that 14 of its 16 nominees for Director are independent.** The only members of the Board that are not independent are Mr. Fanning, Chairman and CEO of the Company, and Mr. Womack, President of the Company. Ms. Juanita Powell Baranco, who retired at the 2022 annual meeting, is also independent.

**Board Leadership Structure**

Our Corporate Governance Guidelines and our By-Laws allow the independent Directors to determine the appropriate Board leadership structure for Southern Company, including the flexibility to split or combine the Chairman and CEO responsibilities. The independent Directors annually review our Board leadership structure to determine the structure that is in the best interests of the Company and its stockholders.

The Board believes that its current leadership structure, which has a combined role of Chairman and CEO counterbalanced by a strong independent Board led by an empowered Lead Independent Director, active and engaged independent Directors and fully-independent Board committees chaired by independent Directors, has provided the optimal balance between independent oversight of management and unified leadership for the Company for many years and has been in the best interests of the Company and its stockholders.

As part of the CEO succession planning process, the Board committed to undertake a comprehensive review of its leadership structure in conjunction with a CEO transition, including consideration of different possible leadership structures.

Board Leadership Review

The Nominating, Governance and Corporate Responsibility Committee, in conjunction with the Succession Committee, helped lead our Board in evaluating its current leadership structure and the leadership structure that would best serve stockholders at the time of the CEO transition. The Nominating, Governance and Corporate Responsibility Committee's process, in conjunction with the Succession Committee, included a comprehensive review and analysis of current and emerging best practices with respect to board leadership structure. The Committees reviewed an analysis undertaken by outside counsel that examined, among other things, board leadership practices and recent trends among large public companies and peer utility companies, studies regarding the impact of board leadership structure on company performance and published views of significant Company stockholders on board leadership structure.

In addition, we engaged with stockholders to solicit feedback on board leadership structure and shared that feedback with the Nominating, Governance and Corporate Responsibility Committee. The Chair of the Nominating, Governance and Corporate Responsibility Committee also engaged directly with key stockholders to solicit feedback on board leadership structure. While several stockholders expressed a preference for an independent board chair, stockholders representing a significant portion of our stock ownership did not indicate a preferred board leadership structure but rather expressed

**Corporate Governance at Southern Company**

confidence in deferring to the Board's judgment on its leadership structure so long as the Board maintains independent board leadership through an empowered lead independent director.

The Nominating, Governance and Corporate Responsibility Committee, in conjunction with the Succession Committee, also considered whether a combined chairman and CEO, an executive chairman or an independent board chair would best facilitate the Company's achievement of its strategic priorities, including its decarbonization efforts to meet its long-term GHG emission reduction goal of net zero by 2050, fleet transition plans to meet both the interim goal and the 2050 goal and enterprise-wide capital allocation plans.

After completing its review, the Nominating, Governance and Corporate Responsibility Committee, in conjunction with the Succession Committee, recommended to our independent Directors that at the time of the retirement of our current CEO, Mr. Fanning, our Company will be best served by a leadership structure consisting of Mr. Fanning as Executive Chairman, Mr. Womack serving as CEO and an independent Director appointed by the Board's independent members, currently Mr. Grain, serving as Lead Independent Director. The independent Directors concluded that our Company and its stockholders will be best served by this leadership structure, which will position the Company for a successful onboarding of Mr. Womack into the CEO role and maintain robust independent Board leadership through a Lead Independent Director and fully independent Board committees chaired by independent Directors.

Key Responsibilities and Duties of Leadership Roles Effective after the Annual Meeting

The leadership structure of Mr. Fanning, our retiring CEO, serving as Executive Chairman, Mr. Womack serving as CEO and Mr. Grain serving as Lead Independent Director, will be effective immediately following the annual meeting. Each role will have clearly delineated responsibilities, as outlined below.

**Corporate Governance at Southern Company**

The Lead Independent Director is elected by the independent Directors of the Board to serve in the role for a period of generally two to three years. The Board's succession planning process includes the regular review of the skills, qualifications, attributes and experiences of the independent Directors to identify potential future candidates for the Lead Independent Director role.

**Role of the Independent Directors**

The Board has strong, independent Directors that provide additional independent leadership to the Board and effective oversight of management.

The independent Directors are free to raise subjects at a Board meeting that are not on the agenda for that meeting. An executive session, which allows the independent Directors to meet without the Chairman and CEO present, is included on the agenda of every regular board meeting.

All of the Board's six standing committees are comprised solely of independent Directors, and independent Directors chair all of these committees. Each Board committee has a designated member of senior management, other than the Chairman and CEO, that works with the independent Director that chairs that committee to develop the committee's agenda for each meeting. The independent Director that chairs each committee reviews and approves the agenda and materials to be covered at the upcoming meeting. The independent Directors are free to raise subjects at a committee meeting that are not on the agenda for that meeting. An executive session is included on the agenda of every regular committee meeting.

The independent Directors evaluate the performance of the Chairman and CEO at least annually. The Lead Independent Director, in conjunction with the chair of the Compensation and Talent Development Committee, is responsible for overseeing the evaluation process. Input on the Chairman and CEO's performance is sought from all of the independent Directors. The Lead Independent Director facilitates a robust discussion of the evaluation results with the independent Directors while meeting in executive session. The Lead Independent Director and the chair of the Compensation and Talent Development Committee together discuss the evaluation with the Chairman and CEO. The evaluation is used by the Compensation and Talent Development Committee to determine the compensation to be recommended for ratification by the independent Directors.

**Board Continuing Education**

Directors are encouraged to participate in continuous learning in an effort to promote the investment in knowledge on matters relevant to the Company. On a quarterly basis, we provide our Directors with suggested educational courses on topics including emerging governance issues, compliance and ethics matters, financial and risk oversight and industry-specific subjects. To facilitate ongoing education by our Directors, we pay the costs for registration, tuition and related travel and lodging expenses.

**Board and Committee Responsibilities**

**Oversight of Strategy**

The Board and its Committees provide oversight of the Company's business strategy throughout the year. Various elements of strategy are discussed at every Board meeting, as well as at many meetings of the Board's Committees, and the Board receives regular updates on progress and execution from, and provides guidance to, our management team.

The Board dedicates at least one meeting each year to a deep dive on strategic planning and oversight. These sessions create a dedicated forum for a fluid exchange of viewpoints and ideas on the Company's strategic direction and identifying new opportunities and risks as management executes upon the Company's strategy. In 2022, the Board participated in an

expanded off-site strategy session that included presentations by internal and third-party experts focused on emerging technologies and innovation required for the Company to flourish in a new energy economy. Presentations by internal leaders highlighted endeavors occurring throughout the Company to assess, invest in and deploy innovative solutions and drive outcomes, customer satisfaction, revenue growth and retention and risk mitigation.

**Oversight of Risk**

The Board and its committees have both general and specific risk oversight responsibilities. The Board has broad responsibility to provide oversight of significant risks primarily through direct engagement with management and through delegation of ongoing risk oversight responsibilities to the committees. Any risk oversight that is not allocated to a committee remains with the Board.

At least annually, the Board reviews our risk profile to ensure that oversight of each risk is properly designated to an appropriate committee or the full Board. The charters of the committees and the checklist of agenda items for each committee define the areas of risk for which each committee is responsible for providing ongoing oversight.

**Corporate Governance at Southern Company**

Each committee provides ongoing oversight for each of our most significant risks designated to it, reports to the Board on their oversight activities and elevates review of risk issues to the Board as appropriate. Each committee has a designated member of executive management as the primary responsible officer for providing information and updates related to the significant risks for that committee. These officers ensure that all significant risks identified in the risk profile we develop are regularly reviewed with the Board and/or the appropriate committee(s).

Southern Company has a robust enterprise risk management program that facilitates identification, communication and management of the most significant risks throughout the Company employing a formalized framework in which risk governance and oversight are largely embedded in existing organizational and control structures. As a part of the governance structure, the CFO serves as the Chief Risk Officer and is accountable to the CEO and the Board for ensuring that enterprise risk oversight and management processes are established and operating effectively.

All Directors are actively involved in the risk oversight function, and we believe that our leadership structure supports the Board's risk oversight responsibility. Each committee is chaired by an independent Director, and the Chairman and CEO does not serve on any committee. There is regular, open communication between management and the Directors.

**Oversight of Key ESG Risks**

The Board's oversight of strategy and risks includes oversight of key ESG matters, including climate, human capital, diversity, equity and inclusion, safety and cybersecurity. These matters are important to the long-term success of the Company and, accordingly, are integrated into topics reviewed and discussed at each Board meeting as well as the Board's annual in-depth strategy session.

Our Committee structure facilitates oversight of ESG issues that impact many areas of our business.

&nbsp;&nbsp;► **Audit Committee** oversees the adequacy and effectiveness of internal controls, including the development of internal controls for non-financial ESG-related data and disclosures<br> ► **Business Security and Resiliency Committee** oversees cybersecurity, physical security and operational resiliency, including issues and policies relating to climate change and adaptation and its impact on business resiliency<br> ► **Compensation and Talent Development Committee** oversees human capital management strategies, practices and programs, including talent acquisition, development and retention; diversity, equity and inclusion; employee engagement and well-being; performance management; and pay equity reviews<br> ► **Finance Committee** oversees capital deployment, including alignment of long-term capital allocation strategies with net zero objectives<br> ► **Nominating, Governance and Corporate Responsibility Committee** oversees significant corporate responsibility strategies, programs and practices, including environmental sustainability and climate change, supporting community investment and social justice, advancing supplier diversity, public policy advocacy, political contributions and lobbying and assessing ESG feedback from stockholders and other stakeholders<br> ► **Operations, Environmental and Safety Committee** oversees reduction of GHG emissions and fleet transition, including net zero carbon strategies, resource planning, emerging technologies and R&D and the impact on employees and communities of implementing the business strategies and operations<br>

**Oversight of Cybersecurity**

Cybersecurity is a critical component of our risk management program. The Board devotes significant time and attention to overseeing cyber and information security risk, and our strong approach to cybersecurity governance establishes oversight and accountability at every level of the enterprise. The Board's Business Security and Resiliency Committee, comprised solely of independent Directors, is charged with oversight of risks related to cybersecurity and operational resiliency. The Business Security and Resiliency Committee includes directors with an understanding of cyber issues and with high-level security clearances.

► The Business Security and Resiliency Committee meets at every regular Board meeting and when needed
 in the event of a specific threat or emerging issue. The Chair of the Business Security and Resiliency Committee regularly
 reports out to the Board on key matters considered by the Committee.

► The Business Security and Resiliency Committee routinely receives presentations on a range of topics, including the threat
 environment and vulnerability assessments, policies and practices, technology trends and regulatory developments.

► The Chief Information Security Officer reports to the Business Security and Resiliency Committee at each committee meeting.

**Corporate Governance at Southern Company**

We use a risk-based, "all threats" and "defense in depth" approach to identify, protect, detect, respond to and recover from cyber threats. Recognizing that no single technology, process or business control can effectively prevent or mitigate all risks, we employ multiple technologies, processes and controls, all working independently but as part of a cohesive strategy to minimize risk. This strategy is regularly tested through auditing, penetration testing and other exercises designed to assess effectiveness.

► Overall network security efforts are led by the Chief Information Security Officer and the Technology
 Security Organization. We utilize a 24/7 Security Operations Center, which facilitates real-time situational awareness across
 the cyber-threat environment, and a robust Insider Threat Protection Program and Fusion Center that leverages cross-function
 information sharing to assess insider threat activity.

► We emphasize security and resiliency through business assurance capabilities and incident response plans designed to identify,
 evaluate and remediate incidents when they occur. We regularly review and update our plans, policies and technologies and
 conduct regular training exercises and crisis management preparedness activities to test their effectiveness.

► We have implemented a security awareness program designed to educate and train employees at least annually, or more often
 as needed, about risks inherent to human interaction with information and operational technology.

► Our cybersecurity program increasingly leverages intelligence sharing capabilities about emerging threats within the energy
 industry, across other industries, with specialized vendors and through public-private partnerships with government intelligence
 agencies. Such intelligence allows us to better detect and work to prevent emerging cyber threats before they materialize.

► Our robust cybersecurity policies and standards across the system, many of which are governed by multiple regulatory requirements,
 are regularly audited by the Federal Energy Regulatory Commission and the Nuclear Regulatory Commission, and periodically
 evaluated by third parties such as cybersecurity insurance carriers.

&nbsp;&nbsp;► The U.S. Department of Homeland Security has granted Certification for the Company's cybersecurity risk management program under the Support Anti-Terrorism by Fostering Effective Technologies Act of 2002.<br> ► Our CEO co-chairs the Electricity Subsector Coordinating Council, which coordinates industry and federal government preparation for and response to potential national disasters and cyber-attacks.<br> ► Members of senior management have high-level security clearances to facilitate access to critical information, and we participate in pilot programs with industry and government to share additional information and strengthen cybersecurity and business resiliency.<br>

**Succession Planning and Talent Development**

Valuing and developing our people is a strategic priority for our Company. To support this priority, we engage in detailed discussions around succession planning and talent development at all levels within our organization. We have robust discussions and actions that occur throughout the year. The Board meets potential leaders at many levels across the organization through formal presentations and informal events on a regular basis.

The Compensation and Talent Development Committee oversees the development and implementation of succession plans for senior leadership positions.

► The process starts with management
 undertaking a full internal review of performance and development of leaders across the organization.

► Management presents and discusses with the Compensation
 and Talent Development Committee its evaluation and recommendations for senior leadership succession regularly throughout
 the year. This review includes an assessment of the current readiness of potential successors and development actions necessary
 for identified individuals.

► The Compensation and Talent Development Committee
 updates the Board on these discussions.

The Compensation and Talent Development Committee is also regularly updated on key talent indicators for the overall workforce, including diversity, equity and inclusion, recruiting and development programs.

**Corporate Governance at Southern Company**

**The Board annually reviews succession plans for senior management and the CEO, including both a long-term succession plan and an emergency succession plan.** To assist the Board, the CEO annually provides his assessment of senior leaders and their potential to succeed in key senior management positions. The evaluation is done in the context of the business strategy with a focus on risk management.

For a description of the additional CEO succession process undertaken during 2021 and 2022, see page 33.

**Political Engagement and Oversight**

As a leading energy company that serves many communities through our subsidiaries, it is important to Southern Company's business success to participate in the political process. We make political contributions in compliance with the laws and regulations that govern such contributions and in alignment with our commitment to act with integrity. We also engage directly with lawmakers and regulators on issues of importance to the Company and its stakeholders. Constructive relationships with policymakers allow our subsidiaries to deliver clean, safe, reliable and affordable energy to customers.

We have put in place decision-making and oversight processes for political expenditures and all governmental relations activities. Both management and the Board play important roles in these governance processes, including independent Director oversight of political expenditures and lobbying activities by our Nominating, Governance and Corporate Responsibility Committee. This also includes periodic review of governmental relations activities by our internal auditing organization to assess compliance with applicable laws and Company policies and procedures, the findings of which are reported to our Audit Committee.

As part of our commitment to good governance, we regularly review our disclosures against best practices. We have also engaged with our stakeholders on this topic in recent years.

As a result of our internal review and stakeholder feedback, in recent years we made the following enhancements to our political engagement and advocacy disclosures.

&nbsp;&nbsp;► We published our *2021 Trade Association and Climate Engagement Report* in October 2022 to provide additional transparency by bringing together existing disclosures and providing analysis and insight into our net zero advocacy positions and memberships in trade associations, along with an assessment of whether the climate change statements or positions of key trade associations are aligned with the goals of the Paris Agreement.<br> ► We describe the principles and public policy advocacy positions that are representative of the views we express in our engagements on climate-related matters.<br> ► Our Report on Political Engagement Disclosures includes political contributions made by our subsidiaries and the lobbying dollars spent by trade associations that lobby at the state level and to which our subsidiaries pay annual dues of $50,000 or more.<br> ► Our website highlights disclosure from our annual response to CDP, which provides a broader list of trade associations, groups and coalitions of which we are members and that are likely to influence climate-related policy.<br> ► Our updated Overview of Southern Company Policies and Practices for Political Engagement tracks the above enhancements.<br>

These disclosures can be found in the Sustainability/ESG section of our website under Policy Engagement and Advocacy at *investor.southerncompany.com*.

Our robust political engagement disclosures evidence our commitment to transparency, accountability and strong corporate governance. We were recognized as a "Trendsetter" by the 2022 CPA-Zicklin Index of Corporate Political Disclosure and Accountability.

**Board Governance Processes**

**Board and Committee Self-Evaluation Process**

The Board and each of its committees have a robust annual self-evaluation process.

---

| | | |
|:---|:---|:---|
| **1** | **Board Evaluation** | The Lead Independent Director, in conjunction with the Nominating, Governance and Corporate Responsibility Committee, oversees the annual self-assessment process on behalf of the Board. |
| **2** | **Committee Evaluations** | The charter of each committee of the Board also requires an annual performance evaluation, which traditionally is overseen by the chair of each committee. |
| **3** | **Interviews and Discussion** | The Board self-evaluation process involves completion of a written questionnaire by each Board member, followed by an interview of each Director conducted by an independent third party. The independent third party reviews the results of the evaluation process with the Lead Independent Director. The Lead Independent Director leads a discussion with the full Board to review the results of the self-evaluation and identify follow up items.<br> The committee self-evaluation process involves a review and discussion for each committee.<br> The process is led by the chair of each committee and is conducted in executive session. |
| **4** | **Outcome** | The objective is to allow the Directors to share their perspectives and consider adjustments or enhancements in response to the feedback. |

---

The Board resumed regular in-person Board meetings during the second half of 2021. As a result of the Board's self-evaluation processes in recent years and its positive experience with the expansion of virtual Board and committee meeting technology during 2020 and 2021, the Board restructured its meeting schedule for 2022 to continue leveraging virtual technology for its committee meetings and continuing to hold in-person Board meetings to use the Directors' time more effectively. The Board is continuing with that approach for 2023.

**Meetings of Non-Management Directors**

An executive session, which allows non-management Directors (our independent Directors) to meet without any members of the Company's management present, is included on the agenda of each regularly-scheduled Board meeting. These executive sessions promote an open discussion of matters in a manner that is independent of the Chairman and CEO. The Lead Independent Director chairs each of these executive sessions.

**Certain Relationships and Related Transactions**

We have a robust system for identifying potential related person transactions.

► Our Audit Committee is responsible for overseeing our Code of Ethics, which includes policies relating
 to conflicts of interest. The Code of Ethics requires that all employees, officers and Directors avoid conflicts of interest,
 defined as situations where the person's private interests conflict, or even appear to conflict, with the interests
 of the Company as a whole.

► We conduct a review of our financial systems to identify potential conflicts of interest and related person transactions.

► At least annually, each Director and executive officer completes a detailed questionnaire that asks about any business
 relationship that may give rise to a conflict of interest and all transactions in which the Company or one of its subsidiaries
 is involved and in which the executive officer, a Director or a related person has a direct or indirect interest.

► We have a Contract Manual and other formal written procurement policies and procedures that guide the purchase of goods
 and services, including requiring competitive bids for most transactions above $10,000 or approval based on documented business
 needs for sole sourcing arrangements.

**Corporate Governance at Southern Company**

The approval and ratification of any related person transaction would be subject to these written policies and procedures which include:

► a determination of the need for the goods and services;

► preparation and evaluation of requests for proposals by supply chain management;

► the writing of contracts;

► controls and guidance regarding the evaluation of the proposals; and

► negotiation of contract terms and conditions.

As appropriate, applicable contracts are also reviewed by individuals in the legal, accounting and/or risk management services departments prior to being approved by the responsible individual. The responsible individual will vary depending on the department requiring the goods and services, the dollar amount of the contract and the appropriate individual within that department who has the authority to approve a contract of the applicable dollar amount.

In addition to the above procedures, the Board has adopted a written policy pertaining to the approval or ratification of related person transactions by the Nominating, Governance and Corporate Responsibility Committee.

In 2022, Ms. Chelsea Tucker, the wife of Dan Tucker, an executive officer of the Company, was employed by Georgia Power as a customer relationship manager administrator and received total compensation of approximately $144,000.

We do not have any other related person transactions that meet the requirements for disclosure in this proxy statement.

In the ordinary course of the Southern Company system's business, electricity and natural gas are provided to some Directors and entities with which the Directors are associated on the same terms and conditions as provided to other customers of the Southern Company system.

**Corporate Governance at Southern Company**

**Director Stock Ownership Guidelines**

Under our Corporate Governance Guidelines, non-employee Directors are required to beneficially own, within five years of their initial election to the Board, common stock of the Company equal to at least five times the annual cash retainer. The annual equity grant for non-employee Directors is required to be deferred until Board membership ends. All non-employee Directors either meet the stock ownership guideline or are expected to meet the guideline within the allowed timeframe.

**Director Deferred Compensation Plan**

The annual equity grant to the independent Directors is required to be deferred in shares of common stock. The shares are not distributed until membership on the Board ends. The deferral is made under the Director Deferred Compensation Plan and earns dividends which are reinvested in additional shares of common stock until distribution. Upon leaving the Board, distributions are made in common stock.

In addition, Directors may elect to defer up to 100% of their remaining compensation in the Director Deferred Compensation Plan until membership on the Board ends. Such deferred compensation may be invested as follows, at the Director's election:

► in common stock units which earn dividends as
 if invested in common stock and are distributed in shares of common stock or cash upon leaving the Board; or

► at the prime interest rate which is paid in cash upon leaving the
 Board.

All investments and earnings in the Director Deferred Compensation Plan are fully vested. For compensation earned prior to 2022, each Director was permitted to make one election to receive compensation deferred through the Director Deferred Compensation Plan upon leaving the Board in either a lump-sum payment or up to 10 annual distributions. In other words, all deferrals made by a Director in the Director Deferred Compensation Plan were subject to one distribution election. Beginning with compensation earned during 2022, each Director may annually elect the manner of distribution of compensation deferred through the Director Deferred Compensation Plan for a calendar year, either a lump-sum payment or up to 10 annual distributions. A distribution election must be made no later than December 31 of the year prior to the year in which the compensation will be earned.

Advisory Vote to Approve Executive Compensation (Say on Pay)

---

| | |
|:---|:---|
| ► | As described in the CD&A beginning on page 58, we believe our compensation program provides the appropriate mix of fixed and at-risk compensation. |
| ► | The short- and long-term performance-based compensation program for our CEO ties pay to Company performance, rewards achievement of financial and operational goals, relative TSR and progress on meeting our GHG reduction goals, encourages individual performance that is in line with our long-term strategy, is aligned with stockholder interests and remains competitive with our industry peers. |
| ![](so4109301-pre14ax58x2.jpg) | The Board recommends a vote **FOR** this proposal |

---

We design our compensation program to attract, engage, competitively compensate and retain our employees. We target the total direct compensation for our executives at market median and place a very significant portion of that target compensation at risk, subject to achieving both short-term and long-term performance goals.

The Compensation and Talent Development Committee believes that our compensation programs effectively align executive pay with performance by:

► Placing the vast majority (92%) of the CEO's
total compensation at risk

► Striking the right balance between short-
 and long-term results

► Selecting appropriate performance metrics, including market-based
measures such as relative TSR, long-term value creation metrics such as EPS and ROE, progress in meeting GHG reduction goals (for
the CEO, the CFO and the EVP of Operations), annual operational goals and individual performance goals that drive our long-term
business strategy

► Actively evaluating the impact of any EPS adjustments on compensation decisions

► Exercising its discretion to reduce payouts to ensure alignment with stockholder interests and feedback

At our 2022 annual meeting, we received 95% support of votes cast on our executive compensation program.

Throughout 2022 and into 2023, we continued our robust stockholder outreach program. Our independent Directors, including our Lead Independent Director, the Chair of our Compensation and Talent Development Committee and the Chair of our Nominating, Governance and Corporate Responsibility Committee, have participated in key engagements. Feedback from our stockholders is carefully considered by the Compensation and Talent Development Committee in making compensation decisions.

Stockholders are voting to approve, on an advisory basis, the following resolution:

*"RESOLVED, that the stockholders approve the compensation of the named executive officers described in the Compensation Discussion and Analysis, the Summary Compensation Table and the other compensation tables and accompanying narrative in the proxy statement."*

Although it is non-binding on the Board, the Compensation and Talent Development Committee will review and consider the vote results when making future decisions about the executive compensation program.

Advisory Vote to Approve Frequency of Future Advisory Votes on Executive Compensation (Say on Frequency)

---

| | |
|:---|:---|
| ► | Shareholders are being provided the opportunity to vote on the frequency of the advisory vote to approve executive compensation (Say on Frequency), which is required at least once every six years. The frequency options are to hold the advisory vote every one, two or three years. In both 2011 and 2017, the Board recommended and the stockholders voted overwhelmingly in favor of holding the Say on Pay vote every year. The Board continues to believe that the Say on Pay vote should be held every year. |
| ![](so4109301-pre14ax58x2.jpg) | The Board recommends a vote for **ONE YEAR** for this proposal |

---

In addition to requiring a Say on Pay advisory vote to approve executive compensation described in Item 2 above, the securities laws require us to hold an advisory vote on the frequency of the Say on Pay vote (Say on Frequency) at least once every six years. The last Say on Frequency vote was held in 2017, where the Board recommended and stockholders voted in favor of holding the Say on Pay vote every year. We have provided an annual Say on Pay vote each year since 2011.

We are again asking stockholders to indicate their preference for how often to hold the Say on Pay vote – every one, two or three years. After considering the options, the Board determined that having a Say on Pay vote every year continues to be the most appropriate option for the Company.

The Compensation and Talent Development Committee carefully considers executive compensation program decisions each year, taking stockholder feedback into account in making those decisions. The Board believes that an annual Say on Pay vote is an important part of that process.

Although it is not binding on the Board, the indicated preference of stockholders as expressed through this Say on Frequency vote will be taken into consideration when making future decisions regarding the frequency of future Say on Pay votes.

| &nbsp;&nbsp;**2022 Compensation Decisions for our Executive Leadership** | &nbsp;&nbsp;**2022 Compensation Decisions for our Executive Leadership** |
| &nbsp;&nbsp;► | Calculated incentive compensation payouts for 2022 reflect the Company's robust operational performance, including a consistent focus on system reliability, enhanced cyber and physical security measures and the delivery of strong adjusted financial results for our stockholders. |
| &nbsp;&nbsp;► | The CEO's leadership remained critical to the Company's overall success in 2022. The Committee's evaluation of the CEO's performance considered a number of factors, including: |

---

**●** The CEO maintained focus on our key operational and customer service objectives, oversaw constructive regulatory outcomes across several subsidiaries and helped to ensure our hiring, training and retention practices remained robust within a tight labor market and evolving economic uncertainties.

**●** The CEO was also instrumental in the continued execution of our long-term strategy, including divesting of non-core assets and furthering focus on our regulated utility business lines.

**●** The CEO maintained a continued focus on the transition of our generating fleet to lower GHG emitting sources and targeted opportunities to reduce emissions across the energy value chain.

**●** The CEO led meaningful progress at Plant Vogtle Units 3 and 4, though challenges resulted in net charges against earnings for 2022.

► Consistent with its historical approach to aligning pay with performance and stockholder interests related to earnings impacts from the construction at Plant Vogtle, the Committee applied negative discretion to reduce the calculated 2022 short-term incentive payout for the CEO by approximately $1.7 million.

► For other members of senior management, one of whom is an NEO, certain Vogtle-related performance awards were forfeited as of December 31, 2022 due to delay in the completion of specific milestones for the Plant Vogtle Units 3 and 4 construction project. The value of the forgone awards was in excess of $2.5 million.

| &nbsp;&nbsp;► | **Strategic Enhancements to Short-Term and Long-Term Incentive Compensation Program Aligned with our Decarbonization Strategy** |

---

► **Short-Term Incentive Compensation Net Zero Availability:** Added new operational metric that measures the availability
 of zero-carbon generation resources, such as nuclear, solar, wind, etc., aligned with our efforts to increase our renewable
 and carbon-free generation footprint

► **Long-Term Incentive Compensation GHG Reduction Goal:** Enhanced several components of the GHG
 emission reduction goals:

**●** Extended participation beyond the CEO to two additional
 senior executives, including the CFO and the EVP of Operations

**●** Refined targets to better reflect renewable resource capacity factors
 and battery storage

**●** Broadened the range of the qualitative assessment to more accurately

| Under the leadership of our Chairman and CEO Tom Fanning, these successes facilitated the Company's goal of delivering long-term value to stockholders with appropriate risk-adjusted TSR. Underpinning these successes is our commitment to excel at the fundamentals, which includes prioritizing customers and communities, as well as focusing on the well-being of our employees. See page 8 for the 2022 Company performance overview.<br> In early 2023, the Company announced a CEO succession plan that was the culmination of a robust succession planning process, as described on page 33. The Chair of the Compensation Committee was a member of the Succession Committee that led the process.<br> **Compensation Committee Oversight and Engagement**<br> We remained actively engaged in our oversight responsibilities for executive compensation, leadership and talent development, and human capital management, including a continued focus on employee health and well-being. We aim to implement compensation programs that are:<br> ► Designed and administered to drive long-term value creation for our stockholders;<br> ► Reflective of feedback from our ongoing stockholder engagement program;<br> ► Responsive to the dynamic environments in which our executives and workforce operate;<br> ► Supportive of the Company's plan to reduce GHG emissions and meet its interim and net zero goal; and<br> ► Aligned with our compensation beliefs.<br> The five independent Directors serving on our Committee bring a diverse range of qualifications, attributes, skills, experiences and perspectives to our decision making. Our Committee members currently include the Chairs of our Board's Finance Committee and Operations, Environmental and Safety Committee, both of whom provide constructive insights on both our rigorous compensation plan design and annual performance assessments. We are committed to aligning pay with performance each year; hiring, developing and retaining a diverse pool of talent; and promoting alignment of our compensation program with the Company's long-term strategy and stockholders' expectations. | Building on the foundation we created over the past several years, we continued our strong and active involvement in stockholder outreach, which includes independent Director participation in key engagements. Directors directly engage with stockholders and receive regular updates from management on our stockholder engagement program.<br> Below is an overview of the Committee's key focus areas over the past year.<br> **Succession Planning**<br> ► In addition to the CEO succession process, we maintained our focus on succession planning for other members of the senior management team. Several management changes at our regulated utilities were also announced in early 2023 as part of the Company's comprehensive succession and management transition plan. We believe that these leadership changes will deepen the strength of the Company's management bench. We continue to test and refine our robust talent pipeline to help ensure that it can provide the same dynamic, visionary and capable leaders.<br> ► Our Committee met and discussed senior leadership talent and the overall company-wide talent management process throughout the year, and facilitated regular exposure, through Board meetings and other opportunities, to high potential employees throughout 2022.<br> **Human Capital Management**<br> ► Management teams of several Company subsidiaries provided regular human capital updates on their specific initiatives for employee attraction, engagement and retention; diversity, equity and inclusion initiatives and results; pay equity analysis; and employee feedback and outreach efforts and results.<br> ► In light of continuing tight labor market conditions and evolving economic uncertainty, we analyzed and refined our total rewards to meet the diverse needs of our employees, including the executive team, and to attract and retain talent in a constantly evolving market. We reviewed and studied multiple reliable sources of wage and economic data (nationally, regionally, within the industry and across other companies) to maintain competitiveness within our markets.<br> ► We continued supporting employees by offering remote and hybrid work schedules, providing flexibility, while focusing on employee well-being. |

| **Compensation Metrics that Support GHG Reduction Goals and Sustainable Business Practices**<br> ► We have received positive feedback from our stakeholders on our approach to aligning a meaningful portion of the CEO's long-term equity incentive award to the Company's 2030 and 2050 GHG emission reduction goals. We continued this practice in 2022 and into 2023.<br> ► We enhanced several components of our long-term incentive GHG emission reduction goals for the 2022 performance year:<br> &nbsp;&nbsp;&nbsp;&nbsp;● Extended the application of the GHG goal to two additional senior executives, including the CFO and the EVP of Operations,<br> &nbsp;&nbsp;&nbsp;&nbsp;● Refined targets to consider renewable resource capacity factors and battery storage, and<br> &nbsp;&nbsp;&nbsp;&nbsp;● Broadened the assessment range of the qualitative assessment to include both downside and upside outcomes.<br> ► We continued using operational metrics in the annual incentive compensation program that include safety, workforce diversity, supplier diversity, customer satisfaction and other measures to support our sustainable business model. For 2022, we implemented a new zero carbon resource availability goal for annual incentive compensation.<br> **CEO Performance Assessment**<br> ► We reviewed and approved the CEO's performance goals for 2022 and engaged in ongoing performance assessment dialogue throughout the year.<br> ► Utilizing an independent third-party, we facilitated the CEO performance review with the independent members of the Board.<br> **Compensation Plan Design and Alignment with Business Strategy and Stockholder Interests**<br> ► We conducted our annual rigorous program evaluation to assess our incentive plan design's effectiveness at striking the right balance between short- and long-term results and is aligned with business strategy, key financial objectives and stockholder interests.<br> ► We believe our compensation plan design works as intended to align CEO performance with the long-term strategy of our business and value creation for stockholders. To that end, we have re-aligned a significant portion of the CEO's performance-based long-term incentive compensation previously linked to cash flow | &nbsp;&nbsp;&nbsp;&nbsp;from operations to financial metrics (TSR and ROE) to be more directly aligned with our stockholders interests. More details are on page 67.<br> ► Our Committee continued active engagement in assessing goal rigor and evaluating earnings adjustments that impact compensation, both positive and negative, in making payout decisions by considering (1) management's control over the item, (2) whether the item was contemplated in the financial plan, (3) alignment of pay outcome with stockholder impact and (4) alignment of pay outcome with management accountability.<br> **2022 Incentive Compensation Pay Decisions for the CEO and Other Executives**<br> 2022 was a year in which our businesses continued to demonstrate operational excellence and executed on our strategic vision, positioning the Company to create shareholder value for years to come. We maintained our exceptional track record of strong reliability and outstanding customer service while remaining focused on the well-being of our employees.<br> The outstanding leadership demonstrated by the CEO and executive team was key to the Company's successes throughout the year. These successes included finishing at the top end of our 2022 EPS goal on an adjusted basis, exceeding our 2022 operational goals and our 2020-2022 GHG reduction target goal as well at finishing in the top quartile of our peers on our three-year TSR goal.<br> The Company made substantial progress on Plant Vogtle Units 3 and 4 during 2022, including completing fuel load for Unit 3. Despite the progress, increases to the total project capital cost forecast resulted in net after-tax charges to income for 2022 of $137 million, or $0.13 per share.<br> Consistent with prior years and our focus on aligning pay with stockholder interests, we felt it was appropriate to take into account these charges against earnings for 2022 when considering executive compensation payouts. Accordingly, we applied negative discretion to reduce the calculated CEO 2022 annual incentive payout by approximately $1.7 million.<br> For certain other members of senior management, including one NEO, certain Vogtle-related performance awards were forfeited as of December 31, 2022 due to the delay in the completion of specific Plant Vogtle Unit 3 and 4 construction project milestones. These performance awards were designed to provide accountability and link these executives' compensation to the successful completion of milestones in accordance with the schedule approved by the Georgia PSC. The value of the forgone awards was in excess of $2.5 million. |

CEO Pay Aligned with Long-Term Total Shareholder Return

We continue to create significant long-term stockholder returns through stock price appreciation and dividends paid to our stockholders. The chart below demonstrates the link between CEO incentive pay and the Company's three-year stock price performance relative to the industry peer group for the years from 2020 through 2022.

► The majority of the CEO incentive compensation was tied to stockholder value created from 2020 to 2022 relative to our industry peers\* and strong return on equity results.

► From 2020 through 2022, we have consistently performed in the top quartile of our TSR peer group for each 3-year performance period and significantly above the median TSR for the peer group.

|:---|:---|
| **Strong adjusted EPS growth for 2020–2022 allowed us to deliver consistent dividend growth for stockholders**<br> ► Over the last three years, we continued to deliver strong adjusted EPS results at or above the top end of our projected EPS guidance ranges. These results were driven by a combination of constructive regulatory outcomes for customers and stockholders and effective cost discipline. More details on our performance can be found at page 8.<br> ► This performance has enabled us to increase dividends per share for 21 consecutive years. Moreover, we have paid a dividend equal to or greater than the prior year for the last 75 years.<br> Reported EPS was $2.95 in 2020, $2.26 in 2021 and $3.28 in 2022. For a reconciliation of adjusted EPS to EPS under GAAP, see page 125. | ![](so4109301-pre14ax65x2.jpg) |

CEO Pay Aligned with Consistent Progress toward Reducing GHG Emissions

Starting in 2019, we aligned a portion of the CEO long-term incentive pay with our GHG emission reduction goals. The addition of zero carbon generation resources and the retirement of coal generating units (cumulative megawatt change) has driven progress toward our goal of achieving GHG emissions reductions of 50% from 2007 levels by 2030 and net zero by 2050. Achievement for the 2020-2022 performance period quantitative metric and qualitative modifier above target is consistent with the Company's progress in its decarbonization efforts. More details can be found on page 77.

**CEO Target Pay Decisions**

► In consultation with its independent consultant, the Committee carefully evaluated the CEO compensation of peer utility companies, assessing the relative size and complexity of each to Southern Company. Based on Southern Company falling within the top decile of its compensation peer group, based on market capitalization, and considering the outstanding performance of the CEO, the Committee approved the following changes for 2022: increased base salary by $100,000, increased target PPP opportunity from 190% to 200% of base salary, and increased target LTI opportunity from 875% to 975% of base salary.

► These changes were made in recognition of the importance of the CEO's instrumental leadership in guiding the Company as we achieved major milestones on the nation's largest construction project while operating in ever changing market conditions and opportunities. For the past 13 years, our CEO has led the development of our clean energy strategy, overseen major construction projects, driven industry-leading operational performance, and led us through several major transactions as we restructured our portfolio of businesses to reduce risk and improve returns. The Committee recognizes the strong leadership of Mr. Fanning within Southern Company and across the utility industry.

► For 2023, the Committee set the CEO's base salary, PPP target opportunity and LTI target opportunity consistent with 2022 amounts in light of the CEO transition during the year.

► The Committee has not yet made compensation decisions for the incoming CEO or Executive Chairman roles. When made, the compensation decisions will be publicly disclosed in accordance with applicable SEC requirements.

**PPP Goal Rigor and Process Used to Set Goals**

► The Committee establishes the financial goals for EPS and net income based on the Company's financial plan and value proposition, focusing on providing regular, predictable and sustainable EPS and dividend growth.

► The Company's goal setting process employs a multi-layered approach and analysis that incorporates a blend of objective and subjective business considerations and other analytical methods to help ensure that the goals are sufficiently rigorous. Goals are calibrated in part based on relative performance versus peer companies.

► No payout under the PPP can be made if events occur that impact the Company's financial ability to fund the common stock dividends.

| **Belief:** When determining payouts on the EPS goal, the Committee remains actively engaged at every regular Committee meeting in reviewing any EPS or net income adjustments |
| In determining EPS adjustments, the Committee considers:<br> ► Whether the item was contemplated in the financial plan<br> ► Whether the item was outside of normal operations (one-time versus recurring item or something outside of management's control) <br> ► Whether the pay outcome would align with stockholder interests<br> In 2022, the Committee applied negative discretion to reduce the CEO's incentive compensation payout as a result of the net charges against 2022 earnings related to the Vogtle construction project. This approach is consistent with prior Committee practice and the Committee's focus on aligning pay with stockholder interests. Since 2017, the cumulative impact of the Committee's exercise of negative discretion on the CEO's calculated incentive payouts related to charges against earnings from large construction projects is a reduction of over $20 million.  |
| Operational Goal Setting Process |
| **Belief:** The Committee believes that operational goal targets should be set at challenging levels to achieve and drive long-term growth and success |
| The Committee establishes operational goals that are primarily based on industry benchmarks, with the objective of delivering top quartile results compared to industry peers. For goals that do not have a comparable industry benchmark, the Committee sets stretch targets to motivate continuous improvement.<br> As part of its goal-setting process, the Committee reviews previous goals and performance along with input from the Operations, Environmental and Safety Committee on operational goals to appropriately align the threshold, target and maximum goals with expected Company performance. |

► If earned, awards are paid in common stock.
 Accrued dividend equivalent units (DEUs) are received only if the underlying award is earned and paid out.

► The number of shares granted was determined by using the target
 value divided by the closing price of common stock on the date the Committee approved the grant (February 16, 2022 for the
 CEO and February 13, 2022 for the other NEOs). PSU awards with performance tied to relative TSR are valued in the Summary
 Compensation Table and Grants of Plan-Based Awards Table using a Monte Carlo analysis, resulting in amounts that differ from
 what is shown in this CD&A. For more information on the valuation of those PSUs and the Monte Carlo value, see the footnotes
 following the Summary Compensation Table and the Grants of Plan-Based Awards Table.

**2022-2024 Performance Share Unit Award**

The PSU award includes financial and market-based performance goals over the three-year performance period from 2022 to 2024 and is further subject to a credit quality threshold requirement.

---

| | | |
|:---|:---|:---|
| **Goal** | **Why it's important** | **What it measures and how we set the goal** |
| Relative TSR | Aligns award with shareholder returns on a relative basis over the performance period | TSR relative to a utility peer group of companies that are believed to be most similar to the Company in both business model and investors. It measures investment gains arising from stock price appreciation and dividends received from that investment. The peer group is described on page 84 and is subject to change based on merger and acquisition activity. |
| Consolidated ROE | Aligns performance with delivering strong sustainable returns on invested capital | Consolidated Southern Company ROE of the traditional electric operating companies, Southern Company Gas and Southern Power |
| GHG Reduction Goal (for CEO, CFO and EVP of Operations only) | Aligns performance with Southern Company's 2030 and 2050 GHG emission reduction goals | GHG reduction goal measures the progress on the Company's emissions reduction commitment through quantitative and qualitative metrics |

---

The financial goal is also subject to a credit quality threshold requirement that encourages the maintenance of adequate credit ratings to provide an attractive return to investors. If the primary credit rating falls below investment grade at the end of the three-year performance period, the payout for the ROE goal will be reduced to zero.

For each of the financial performance measures, a threshold, target and maximum goal was set at the beginning of 2022.

**2022-2024 Long-Term Incentive Award - GHG Reduction Goal for Certain Executives**

To demonstrate our commitment to GHG reduction, including the net zero by 2050 goal, the Committee continued to include a GHG metric in the CEO's 2022 LTI award and approved the addition of the GHG metric to 2022-2024 LTI award of the CFO and the EVP of Operations. A meaningful portion of the 2022 LTI award for these executives is aligned with our GHG reduction goals. This goal has both quantitative and qualitative components.

**Quantitative Metric:** The Committee chose to express the quantitative measure in terms of cumulative change in MWs over the three-year performance period. Expressing the measure as the cumulative change in MWs reflects the transition in our overall generation fleet, as opposed to expressing the measure in the decrease in emissions. If the measure had instead been expressed in terms of the decrease in emissions, results could be impacted by factors outside the Company's control such as annual changes to weather patterns, the strength or weakness of the economy, and fuel prices and availability, potentially resulting in an unwarranted increase or decrease in incentive compensation.

Target performance over the 2022-2024 period is aligned with the trajectory necessary to reduce GHG emissions 50% by 2030, as compared to 2007. The metric utilized is cumulative MW change, which is limited to:

► Adding zero-carbon and renewable energy MWs,
 including energy storage

► Placing coal or gas steam generation units in retirement status
 or inactive reserve (which means no longer available for routine generation operations and dispatch, but available for resiliency
 and reliability)

**Setting the GHG Goal associated with the Long-Term Incentive Award:**

To achieve the Company's goal of reducing GHG emissions 50% by 2030, a significant change in the Company's generation fleet is required over a number of years. The magnitude of change to the generation fleet necessary to meet the Company's 50% GHG reduction goal requires a long-term effort, begun years ago, due to:

► lead times associated with adding new generation
 resources,

► lead times associated with adding new transmission facilities,

► retiring existing generation resources, and

► maintaining reliability and affordability for customers.

These generation changes are "lumpy," meaning that the MW transition does not follow a straight line. Rather, the MW change will be larger in some years than in other years due to the discrete size of individual generation units and the lead times to implement the changes. For the 2022-2024 performance period, the target cumulative MW change was set based on the 2021 projected MW change in 2022-2024 required to meet the Company's goal to reduce GHG emissions by 50% by 2030. The stretch goal was set to accelerate the timing of a 50% reduction in GHG emissions.

Beginning in 2022, we expanded and better differentiated the types of zero-carbon generation that are used to both set the quantitative goal and measure performance against the goal.

► **Wind:** New wind generation will receive
 1.25 MWs credit for each nameplate MW of addition, in recognition of wind's greater capacity factor and associated greater
 GHG reduction benefits per MW than solar.

► **Energy Storage:** Energy storage, either stand-alone or paired
 with solar, with a full-load storage discharge duration of 4 to 8 hours and available for providing capacity and energy benefits
 under the control of Southern Company's fleet operations personnel will receive 0.5 MWs credit for each nameplate MW
 of addition, in recognition of the importance of energy storage in reliably and cost-effectively integrating an increasing
 amount of intermittent renewable generation. Energy storage with a full-load discharge duration of greater than 8 hours will
 receive 0.75 MWs credit for each nameplate MW of addition, in recognition of the importance of long duration energy storage
 to enhance reliance on a high penetration of intermittent renewables.

**Compensation Discussion and Analysis**

**GHG Reduction Goal Cumulative MW Change Comparisons**

The GHG goal is based on the cumulative, realized actual change in MW over a forward-looking three-year performance period. As the Committee thoughtfully sets each three-year performance goal, it considers the target goal based on the trajectory upon which the 50% GHG reduction by 2030 goal was set and any updates in IRPs that could advance the achievement of such goal. This helps ensure the goal's three-year cumulative MW change will maintain the trajectory necessary to achieve the Company's larger commitment of attaining a 50% GHG reduction by 2030. The stretch goal is set to a level that would drive even more acceleration of the 2030 goal achievement.

Announcements or decisions regarding coal or gas steam generation or additions of zero carbon and renewable generation do not count toward goal performance. Goal performance achievement is based on the actual date when new zero carbon and renewable generation begins commercial operation or when coal or gas steam generation is permanently removed from routine generation operations and dispatch.

► **100% payout target goal:** Set based on
 the 2021 projected MW change in 2022-2024 required to meet the Company's goal to reduce GHG emissions by 50% by 2030.
 Meeting the 100% payout level for 2022-2024 is projected to result in achieving our 50% GHG reduction goal approximately 5
 years early due to exceeding the MW change goal in 2019-2022 and the current projection of exceeding the MW change goal in
 2023-2024.

► **150% payout stretch goal:** Set at a level about 84% greater
 than the target payout, to further accelerate timing of achieving the 50% GHG reduction goal. The threshold for the 2022-2024
 goal has been set to a level equal to about 58% of the 2022-2024 cumulative MW target, preventing any payout if the 2022-2024
 cumulative MW change threshold is not met over the course of the performance period.

Below are the net MW change goals for the 2022-2024 performance period.

<sup>(1)</sup> Goal is expressed in cumulative MW change. Not all MWs have the same GHG emission impacts.

<sup>(2)</sup> Estimated actual reductions in GHG emissions assume average weather, moderate natural gas prices and trend economic growth. Deviations from average weather, natural gas prices or trend economic growth could result in greater or lesser GHG emissions than estimated.

**Qualitative Component:** The qualitative component creates incentives to achieve our 2050 goal through a qualitative assessment. Both the Committee and the entire Board evaluate the CEO's leadership in advancing the energy portfolio of the future. For the 2020-2022 and 2021-2023 grant, the qualitative component is applied as a modifier to the payout determined under the quantitative component, and can result in up to a 30% increase in the overall payout for this goal. The qualitative component was enhanced beginning in 2022 so that it has the potential to not only provide upside, but also downside for failing to achieve expected performance by providing an adjustment ranging from -25% to +50%. The qualitative analysis takes into account:

► Leadership and energy policy (nationally and
 within the industry)

► Decarbonization R&D investments (such as EPRI and Southern
 proprietary R&D)

► Investments (such as corporate venture capital spend and Energy
 Impact Partners)

► New business development (through Southern Power and PowerSecure
 including renewables, distributed generation and distributed infrastructure)

**2020-2022 GHG Reduction Goal PSUs Payout Results for CEO**

**QUANTITATIVE COMPONENT (Achieved at 127% of Target)**

The target goal for the 2020-2022 award is a 1,723 MW cumulative change over the three-year performance period. Over the performance period, the Company achieved 2,270 MWs of fleet transition, representing 127% payout results, through:

► New solar generation placed into service at
 various times over the performance period;

► The 2022 retirement of Plant Wansley and the placement of Plant
 Gadsden Units 1 and 2 on inactive reserve status.

*Note:* The addition of approximately 200 MW of solar and retirement of Plant Wansley was not forecasted or included in the original IRP plans on which the goal was based, so approximately 1,480 MWs associated with changes added upside to the goal achievement. However, the delay of Vogtle Unit 3 and 4's commercial operation had a partially offsetting negative impact on goal achievement since these MWs were not in commercial operation by the end of 2022.

**QUALITATIVE COMPONENT (Achieved at +30%)**

The Committee in conjunction with the Operations, Environmental and Safety Committee and the Board has assessed the performance of the CEO with regards to his leadership in advancing the energy portfolio of the future to have exceeded expectations (Modifier = 30%). While the quantitative component focuses on near-term decarbonization and achieving the Company's 2030 goal, the activities and achievements assessed for the qualitative component help ensure the Company can achieve the long-term 2050 net zero goal. The activities and achievements assessed in the qualitative component focus on constructive engagement in energy and climate policy, R&D to advance the set of technologies that will be needed to reliably and affordably fully achieve the goal of net zero GHG emissions, and to aid other utilities and decarbonization efforts for society at-large. The Committee, in conjunction with the Operations, Environmental and Safety Committee, noted a number of 2020-2022 actions that aid our ability to achieve net zero:

● Signed onto C2ES climate letter to Senate Majority Leader Schumer and House Speaker Pelosi calling for Congress to refocus on Build Back Better climate provisions

● Participation and engagement by key employees in COP 27

● Completed world's largest hydrogen-natural gas fuel blending at Plant McDonough-Atkinson that demonstrated blending of up to 20% hydrogen, an industry first for an advanced-class gas turbine, and resulted in a ~7% reduction in CO2 emission

● Participating in a DOE-funded project to complete a front-end engineering design (FEED) study for an advanced direct air capture system that capitalizes on thermal heat from a nuclear unit

● Supported commercialization of CarbonBuilt's low-carbon concrete process which reduced carbon footprint of concrete products by over 80% at concrete masonry production facility in Alabama

● Completed installation of Integrated Effects Test facility – world's largest chloride salt system – at TerraPower's labs, marking a crucial milestone in development of the Molten Chloride Fast Reactor and continuing work by Southern Company and TerraPower under the DOE Advanced Reactor Concepts award, a multiyear effort to promote the design, construction and operation of Generation-IV nuclear reactors

● Began testing a novel algae culture system at the National Carbon Capture Center from Helios-NRG, which is developing technology to capture CO2 from flue gas and produce marketable, valuable products in a variety of industries, from nutraceuticals to biofuels

● Commenced commercial operation of the 72 MW (288 MWh), battery-based energy storage resource at Tranquility Solar Facility

**2020 TO 2024 PLANNED AND ACTUAL TRAJECTORY TOWARD CUMULATIVE MW CHANGE GOAL**

![](so4109301-pre14ax83x3.jpg)

&nbsp;&nbsp;&nbsp;**Performance Updates: 2021-2023 and 2022-2024 GHG Reduction Goals**<br> **QUANTITATIVE COMPONENT**<br> ► The target goal for the 2021-2023 award is a 2,291 cumulative MW change. Through the end of 2022, the Company is trending favorably, with a little more than 73% of the target already accomplished through new solar generation placed into service in 2021 and 2022 and several large generation changes expected to occur in 2023.<br> ► The target goal for the 2022-2024 award is a 2,777 cumulative MW change. Through the end of 2022, the Company forecasts exceeding the goal based on zero-carbon generation additions made in 2022 and future anticipated coal unit retirements and zero-carbon generation additions.<br>

**Looking Ahead: 2023-2025 GHG Reduction Goal**

The Committee has continued including the GHG goal as part of the long-term incentive award of the CEO, the CFO and the EVP of Operations for the 2023-2025 performance period. Performance over the period from 2023 to 2025 is aligned with a trajectory to achieve our 50% GHG emission reduction goal as early as 2025, five years ahead of our interim target. The 150% payout stretch cumulative MW change goal for 2023-2025 has been set at a level about 80% greater than the target cumulative MW change goal for the 2023-2025 performance period.

**Consulting Agreement for Mr. Crosswhite**

Mr. Crosswhite voluntarily retired from his role as Chairman, President and CEO of Alabama Power effective December 31, 2022. Mr. Crosswhite entered into a consulting agreement with Southern Company Services, Inc. pursuant to which he will serve as a consultant to facilitate a smooth transition for his successor. The term of the consulting agreement is from January 1, 2023 until June 30, 2023. Under this agreement, Mr. Crosswhite will earn $125,000 in compensation for his services during the term. The consulting agreement contains standard confidentiality and non-solicitation provisions.

**Benefits**

Fulsome summaries of our Benefit Plans can be found in Appendix B - Benefit Plan Summary at page 129.

**Retirement Benefits**

► Employee Savings Plan: Substantially all employees
 are eligible to participate in the Employee Savings Plan (ESP), our 401(k) plan. The NEOs are also eligible to participate
 in the Supplemental Benefit Plan (SBP), which is a nonqualified deferred compensation plan where we can make contributions
 that are prohibited to be made under the ESP due to limits under the tax code.

**Compensation Discussion and Analysis**

► Pension Benefits: Substantially all employees
 participate in a funded Pension Plan. Normal retirement benefits become payable when participants attain age 65. The Company
 also provides unfunded benefits to certain employees, including the NEOs, under two nonqualified plans: the Supplemental Benefit
 Plan (Pension-Related) (SBP-P) and the Supplemental Executive Retirement Plan (SERP). The SBP-P and the SERP provide additional
 benefits the Pension Plan cannot pay due to limits applicable to the Pension Plan.

► Deferred Compensation Benefits: We offer a Deferred Compensation
 Plan (DCP), which is an unfunded plan that permits participants to defer income as well as certain federal, state and local
 taxes until a specified date or their retirement, disability, death or other separation from service.

**Change-in-Control Protections**

► We believe that change-in-control protections
 allow management to focus on potential transactions that are in the best interest of our stockholders. In August 2022, the
 Company amended and restated its change-in-control-related compensation plans, including the Severance Plan and the Benefits
 Protection Plan, to confirm double-trigger vesting treatment and align with market best practices.

► Change-in-control protections include severance pay and, in some
 situations, vesting or payment of incentive awards.

► We provide certain severance payments if there is a change in control
 of the Company and a termination of the executive's employment (either involuntary termination not for cause or voluntary
 termination for good reason), often called a "double trigger".

► Severance payment for the CEO is three times the sum of base salary
 plus PPP opportunity (either at target or, if greater, paid out based on the average achievement from the three prior fiscal
 years). For the other NEOs, severance is two times the sum of base salary plus PPP opportunity (either at target or, if greater,
 paid out based on the average achievement from the three prior fiscal years). No excise tax gross-up would be provided.

**Perquisites**

● The Committee recognizes that permitting limited personal use of system aircraft for certain executives allows them to continue to perform their duties in a safe, secure environment and promotes safe and effective use of their time.For 2022, the Committee approved personal use of system aircraft for Mr. Fanning and Mr. Kuczynski. Amounts are included in the Summary Compensation Table.

● The personal safety and security of employees at home, at work and while traveling is of utmost importance to the Company. Given Mr. Fanning's profile and high visibility, the Committee believes that the costs of his security program are appropriate and a necessary business expense and that we can benefit from the added security measures for him. Costs reported in the Summary Compensation Table reflect the ongoing security services provided during 2022.

**Compensation Governance Practices, Beliefs and Oversight**

**Our Commitment to Provide Equitable Compensation for all Employees**

Our compensation system is designed to promote pay equity throughout the entirety of each employee's tenure. To help ensure compensation is fair, competitive and equitable, we have adhered to several key strategies:

► We pay market-competitive rates. We use highly
 reliable data sources and rigorous compensation analysis to help ensure alignment to the market.

► We adhere to the pay for performance philosophy which allows managers
 to reward employees based on performance within established controls.

► We utilize several additional measures to promote fairness and
 consistency, including strong market data and job pricing, well-defined salary structures, comprehensive merit and incentive
 processes — along with clear procedures for employees to voice concerns.

► When appropriate, pay adjustments may occur in accordance with
 an employee's performance or changes in responsibilities. Adjustments may also occur with ad hoc market-based changes
 or as the result of an equity audit.

**Compensation Discussion and Analysis**

We conduct pay equity audits each year. These audits are performed to evaluate potential inequities or inconsistencies in our pay practices. Since 2020, we have collaborated with an independent third party to perform annual pay equity audits plus periodic wage gap and glass ceiling analyses. Detailed results are reported to the Compensation Committee and senior leadership. High-level results of our 2022 audit were communicated to all employees in early 2023. These annual audits help us evaluate our compensation program and consistently confirm strong pay equity across all operating companies.

The Compensation Committee and senior management remain vigilant in our efforts to help ensure all employees are treated fairly and consistently.

&nbsp;&nbsp;► We have a longstanding commitment to equitable pay at all levels across the Southern Company system. Throughout 2022, we continued our communication and education programs to inform our employees of our longstanding dedication to paying fair and equitable compensation.<br> ► Our commitment aligns closely with the concept of Unquestionable Trust that we find in Our Values. It speaks to our commitment to act with honesty, respect, fairness and integrity in all we do. Simply put, discrimination in any form has no place in our business practices, including those that have to do with employee compensation.<br>

**Clawback of Compensation**

**Clawback Provisions in the Omnibus Plans**

The 2011 Omnibus Plan and the 2021 Omnibus Plan include clawback provisions that apply to PPP and LTI awards granted under those plans. These clawback provisions are triggered if (1) we are required to prepare an accounting restatement due to material noncompliance as a result of misconduct with any financial reporting requirement under the securities laws (a Restatement Trigger), and (2) a participant knowingly or grossly negligently engaged in the misconduct, or knowingly or grossly negligently failed to prevent the misconduct, or if the participant is one of the individuals subject to automatic forfeiture under the Sarbanes-Oxley Act of 2002.

**Clawback Policy**

For incentive-based compensation granted after May 26, 2021, our Clawback Policy provides us with an additional basis to recoup incentive-based compensation from certain members of our senior management, including our NEOs. The Clawback Policy applies in the following circumstances:

► *Restatement:* The Committee may provide
 for the recovery or adjustment of excessive incentive-based compensation from a covered employee if (1) there is a Restatement
 Trigger, and (2) the Committee determines that the covered employee committed misconduct that contributed to the noncompliance
 that resulted in the Restatement Trigger.

► *Detrimental Activity:* The Committee may provide for the
 reduction, forfeiture or recovery of incentive-based compensation with respect to a covered employee if the covered employee
 has engaged in certain detrimental activity (such as certain misconduct or a material violation of our Code of Ethics or applicable
 Company policies) that results in significant financial or operational loss or serious reputational harm to the Company or
 its subsidiaries (a Detrimental Activity Trigger)

The Clawback Policy generally allows for recovery for at least three years prior to the year in which the Committee determines that a triggering event has occurred. This three-year recovery period represents an enhancement over the clawback period under our Omnibus Plans, which allow for the recovery of award payments that are earned or accrued during the 12-month period following the first public issuance or filing that was restated.

The Committee is evaluating the Company's Clawback Policy in light of the issuance of the final SEC rule and NYSE proposed listing requirements and anticipates implementing required updates during 2023.

**Role of the CEO**

► The CEO makes recommendations to the Compensation
 Committee regarding other executive officers with respect to (1) base salary adjustments, (2) PPP targets and individual performance
 achievement payouts and (3) LTI targets. These recommendations are based upon market data provided by the independent compensation
 consultant, the CEO's assessment of each executive officer's performance, the performance of the individual's
 respective business or function and employee retention considerations.

► The Compensation Committee considers the CEO's recommendations
 in approving the compensation for the other executive officers. However, the Compensation Committee makes the final decisions
 with respect to compensation decisions for the executive officers.

► The CEO does not play any role with respect to decisions impacting
 his own compensation.

**Role of the Independent Compensation Consultant**

► The Compensation Committee has retained Pay
 Governance LLC as its independent executive compensation consultant. Pay Governance reports directly to the Compensation Committee.
 A representative of Pay Governance attends meetings of the Compensation Committee, as requested, and communicates with the

 to the Compensation Committee pursuant to a written consulting agreement with the Compensation Committee. Generally, these
 services include advising the Compensation Committee on the principal aspects of our executive compensation program and evolving
 industry practices and providing market information and analysis regarding the competitiveness of our program design and our
 award values in relation to the executives' performance.

► In 2022, Pay Governance provided an annual competitive evaluation
 of target total compensation for the NEOs. Additionally, the Compensation Committee relies on Pay Governance to provide information
 and advice on executive compensation and related corporate governance trends throughout the year. Pay Governance provided
 no services to Company management during 2022.

► The Compensation Committee retains authority to hire Pay Governance
 directly, approve its compensation, determine the nature and scope of its services, evaluate its performance and terminate
 its engagement. The Compensation Committee has assessed the independence of Pay Governance pursuant to the listing standards
 of the NYSE and SEC rules and concluded that Pay Governance is independent and that no conflict of interest exists that would
 prevent Pay Governance from serving as an independent consultant to the Compensation Committee.

**Compensation Discussion and Analysis**

**Prohibition on Hedging and Pledging of Common Stock**

Our insider trading policy includes an "anti-hedging" provision that prohibits Directors and employees (including officers) and certain of their related persons (such as certain of their family members and entities they control) from purchasing or selling, or making any offer to purchase or sell, derivative securities relating to securities of the Company or its subsidiaries. The policy specifies examples of covered derivative securities, including exchange-traded options to purchase or sell securities of the Company or its subsidiaries (so-called "puts" and "calls") or financial instruments, that are designed to hedge or offset any decrease in the market value of securities of the Company or its subsidiaries (including but not limited to prepaid variable forward contracts, equity swaps, collars and exchange funds).

Our insider trading policy also includes a "no pledging" provision that prohibits pledging of our stock for all Southern Company executive officers and Directors.

**Stock Ownership Requirements**

We believe ownership requirements align the interests of officers and stockholders by promoting a long-term focus and facilitating longterm share ownership.

► All of our executive officers are subject to
 stock ownership requirements.

► All of our executive officers are meeting their applicable ownership
 requirements.

► Mr. Fanning exceeds his stock ownership requirements by more than
 seven times.

► Ownership arrangements counted toward the requirements include
 shares held in Company-sponsored plans, phantom stock investments in the DCP and the SBP, and shares beneficially owned by
 the executive officer outside of Company-sponsored plans.

► Because Mr. Crosswhite retired during 2022, he is no longer subject
 to the stock ownership requirements.

**CEO Stock Ownership as of February 28, 2023**

**Tax Deductibility of Compensation**

U.S. tax law limits a public company's deductions to $1 million per year for compensation paid to its CEO, CFO and each of its three other most highly compensated executive officers, as well as to any individual who was subject to the $1 million deduction limitation in 2017 or any later year. There is no exception for qualifying performance-based compensation unless it is pursuant to a written binding contract in effect as of the transition date of November 2, 2017. Certain annual cash incentive awards and equity-based incentive awards made on or before the transition date may satisfy the requirements for deductible compensation and any compensation in excess of $1 million paid to a covered person after 2017 will not be deductible unless it qualifies for transition relief. The Committee continues to retain the discretion to make awards and pay amounts that do not qualify as deductible.

Despite the changes to the tax code, the Compensation Committee continues to believe that a significant portion of our executive officers' compensation should be performance based and tied to pre-approved performance measures.

**Compensation Committee Interlocks and Insider Participation**

The Compensation Committee is made up of independent Directors of the Company who have never served as executive officers of the Company. During 2022, none of the Company's executive officers served on the Board of Directors of any entities whose executive officers serve on the Compensation Committee.

**Column (a)**

Mr. Tucker and Mr. Womack first became NEOs in 2021.

Effective immediately following the conclusion of the 2023 Annual Meeting, Mr. Fanning will relinquish the role of CEO and will assume the role of Executive Chairman of the Board. At such time, Mr. Womack will assume the role of the Company's CEO. During 2022, Mr. Womack served as Chairman, President and CEO of Georgia Power.

Mr. Crosswhite retired from his role of Chairman, President and CEO of Alabama Power effective as of December 31, 2022.

**Column (d)**

This column does not reflect the value of stock awards that were actually earned or received in 2022. Rather, as required by applicable rules of the SEC, this column reports the aggregate grant date fair value of PSUs, PRSUs, and RSUs granted in 2022.

The value reported for the PSUs related to relative TSR and consolidated ROE is based on the probable outcome of the performance conditions as of the grant date, using a Monte Carlo simulation model for the relative TSR portion (57% of the grant value of these PSUs) and the closing price of common stock on the grant date for the consolidated ROE portion (43% of the grant value of these PSUs). No amounts will be earned until the end of the three-year performance period on December 31, 2024. The value then can be earned based on performance ranging from 0% to 200%, as established by the Compensation Committee.

The aggregate grant date fair value of the PSUs (excluding PSUs related to the GHG reduction goals for Mr. Fanning and Mr. Tucker as described below) granted in 2022 assuming that the highest level of performance is achieved is as follows: Fanning — $29,835,000; Tucker - $2,569,978; Womack - $3,484,188; Kuczynski — $3,071,572; and Crosswhite - $3,522,030.

The value reported for the portion of PSUs granted to Mr. Fanning and Mr. Tucker related to the GHG reduction goals in 2022 is based on the closing price of common stock on the date of the grant. No amounts will be earned until the end of the three-year performance period on December 31, 2024. The value then can be earned based on performance ranging from 0% to 225%, as established by the Compensation Committee. The aggregate grant date fair value of the PSUs granted to Mr. Fanning and Mr. Tucker in 2022 related to the GHG reduction goals assuming the highest level of performance is achieved is $3,729,375 and $444,804, respectively.

The amounts in column (d) also reflect the grant date fair value of PRSUs granted to certain of the NEOs in 2022 as described in the CD&A, using the closing price of common stock on the grant date. The aggregate grant date fair value of the PRSUs granted in 2022 and reported in column (d) is as follows: Tucker - $494,227; Womack — $746,612; Kuczynski — $658,194; and Crosswhite - $761,149. Mr. Fanning's 2022 long-term incentive grant did not include PRSUs.

See Note 12 to the financial statements included in the 2022 annual report for a discussion of the assumptions used in calculating these amounts.

**Executive Compensation Tables**

**Column (e)**

The amounts in this column reflect actual payouts under the annual PPP. The amount reported for 2022 is for the one-year performance period that ended on December 31, 2022.

**Column (f)**

This column reports the aggregate change in the actuarial present value of each NEO's accumulated benefit under the applicable Pension Plan and supplemental pension plans (collectively, Pension Benefits) as of December 31 of the applicable year.

The Pension Benefits as of each measurement date are based on the NEO's age, pay and service accruals and the plan provisions applicable as of the measurement date. The actuarial present values as of each measurement date reflect the assumptions the Company selected for cost purposes as of that measurement date; however, the NEOs were assumed to remain employed at any Company subsidiary until their benefits commence at the pension plans' stated normal retirement date, generally age 65. For each of Mr. Tucker and Mr. Womack, the accumulated benefit includes a portion of his Pension Plan benefits which are the subject of a qualified domestic relations order.

Mr. Crosswhite's higher aggregate change in Pension Benefit for 2022 as compared to the amounts reflected for other NEOs is due, in part, to his retirement during 2022, which triggered the usage of the September 2021 single-sum value discount rate, a rate lower than those previously assumed, and resulted in an increase of the actuarial present value of his Pension Benefit.

Pension values may fluctuate significantly from year to year depending on a number of factors as described below, including age, years of service, annual earnings and the assumptions used to determine the present value, such as the discount rate.

**Understanding the Annual Change in Pension Value**

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**No additional pension benefits** | ► | 2022 annual change in pension value is not due to any modifications to the existing pension program or formulas |
| &nbsp;&nbsp;**No additional pension benefits** | ► | Pension formula considers years of service, which has an impact on the year over year change in pension value |
| &nbsp;&nbsp;**Annual changes primarily driven by macroeconomic and non-performance factor changes** | ► | Traditional pension plans are extremely sensitive to interest rate changes, which are macroeconomic factors out of the Company's control |
| &nbsp;&nbsp;**Annual changes primarily driven by macroeconomic and non-performance factor changes** | ► | Unlike the short-term and long-term incentive programs which are purely performance based, pension values are driven mostly by non-performance factors |
| **High prevalence of traditional pension plans in utility industry** | In industries such as the utility industry, traditional pension plans are highly prevalent as they: | In industries such as the utility industry, traditional pension plans are highly prevalent as they: |
| **High prevalence of traditional pension plans in utility industry** | ► | Are the most economically efficient way to provide financial well-being at retirement to our employees |
| **High prevalence of traditional pension plans in utility industry** | ► | Help us retain and protect the significant investment we make in our highly skilled workforce and attract the right talent for the future |
| **High prevalence of traditional pension plans in utility industry** | ► | Align with our business model |
| &nbsp;&nbsp;**Compensation Committee is committed to the ongoing sustainability of the pension plan** | ► | Over the years, the Committee has taken actions to promote the sustainability of pension benefits for the future, shift to a more shared responsibility between employer and employee and meet evolving workforce needs to attract and retain employees |

**Executive Compensation Tables**

The values reported in this column are calculated pursuant to SEC requirements and are based on assumptions used in preparing the Company's audited financial statements for the applicable fiscal years, as described further on page 94. The plans utilize a different method of calculating actuarial present value for the purpose of determining a lump sum payment, if any. The change in pension value from year to year as reported in the table is subject to market volatility and may not represent the value that an NEO will actually accrue or receive under the plans during any given year.

None of the NEOs received above-market earnings on deferred compensation under the DCP in the years reported.

The material provisions of the Company's retirement plans and deferred compensation plans in which NEOs participate are described in the Benefit Plan Summary in Appendix B beginning on page 129.

*Perquisites* includes financial planning, personal use of corporate aircraft and other miscellaneous perquisites.

● The Compensation Committee recognizes that permitting limited personal use of system aircraft for certain executives allows the them to continue to perform their duties in a safe, secure environment and promotes safe and effective use of their time. For 2022, the Compensation Committee approved personal use of system aircraft for Mr. Fanning and Mr. Kuczynski. The amount for Mr. Fanning is $216,466 and for Mr. Kuczynski is $116,236.

**Columns (c), (d) and (e)**

These columns reflect the annual PPP opportunity for the NEOs. The information shown as "Threshold," "Target" and "Maximum" reflects the range of potential payouts established by the Compensation Committee. The actual amounts earned for 2022 are included in column (e) of the Summary Compensation Table. See the ***Annual Incentive Compensation (At Risk)*** discussion beginning on page 68 for additional information.

**Columns (f), (g) and (h)**

These columns reflect the long-term PSUs and PRSUs granted to the NEOs in 2022. The information shown as "Threshold," "Target" and "Maximum" reflects the range of potential shares that can be earned as established by the Committee for the PSUs, while the information shown as "Target" for the PRSUs reflects the number of potential shares that can be earned if the performance condition is met. The grant date fair value is included in the Stock Awards column (column (d)) of the 2022 Summary Compensation Table. See the ***Long-Term Equity Incentive Compensation (At Risk)*** discussion beginning on page 75 for additional information on the 2022 LTI grants.

**Column (i)**

This column reflects the aggregate grant date fair value of the PSUs and PRSUs granted in 2022.

► For the PSUs related to TSR and ROE, approximately 44% of the value of the PSUs is based on the probable
 outcome of the performance conditions as of the grant date using a Monte Carlo simulation model ($79.47), while the other
 approximately 56% is based on the closing price of common stock on the grant date ($66.79).

► For the PSUs related to the GHG reduction goal for Mr. Fanning and Mr. Tucker, the value of these shares is based on the
 closing price of the common stock on the grant date ($66.79).

► The value of the PRSUs is based on the closing price of common stock on the grant date ($66.79). The assumptions used
 in calculating these amounts are discussed in Note 12 to the financial statements included in the 2022 annual report.

These columns reflect the remaining 1/3 of the PRSUs, including DEUs, granted to the NEOs in February 2020 and the remaining 2/3 of the PRSUs, including DEUs, granted to the NEOs in February 2021. The achievement of the respective performance goals for these shares were certified by the Compensation Committee on February 12, 2021 for the shares granted in 2020 and February 13, 2022 for the shares granted in 2021. The PRSUs that vested in 2022, including the DEUs, are reflected in the Option Exercises and Stock Vested in 2022 table. The remaining PRSUs granted in 2020 vest on the third anniversary of the grant date, and the remaining PRSUs granted in 2021 will vest on the second and third anniversaries of the grant date.

These columns also reflect the full number and value of PRSUs granted to the NEOs in February 2022 that vest 1/3 each year for a threeyear period subject to the achievement of a one-year financial performance goal (Southern Company's 2022 cash from operations exceeds the amount paid in dividends in 2021) and associated DEUs on the PRSUs. DEUs only pay out if the underlying shares vest. The Compensation Committee certified the achievement of this goal on February 13, 2023, and the first 1/3 vested upon that certification. The remaining 2/3 will vest equally on the second and third anniversaries of the grant date.

Column (g) also reflects the target number of PSUs that can be earned at the end of each three-year performance period (January 1, 2021 through December 31, 2023 and January 1, 2022 through December 31, 2024). The number of shares reflected in column (g) also reflects the DEUs on the target number of PSUs. DEUs are credited over the performance period but are only received at the end of the performance period if the underlying PSUs are earned.

The PSUs granted for the January 1, 2020 through December 31, 2022 performance period vested on December 31, 2022 and are reported in the Option Exercises and Stock Vested in 2022 table.

The PSUs granted to Mr. Kuczynski in May 2018 are not reflected in column (g) as the remaining 50% of the grant was contingent upon the receipt of the fuel load authorization from the U.S. Nuclear Regulatory Commission for Unit 4 (50%) by December 31, 2022, which did not occur. As of January 1, 2023, these PSUs were forfeited.

The value in column (h) is derived by multiplying the number of shares in column (g) by the common stock closing price on December 30, 2022 ($71.41). The ultimate number of shares earned, if any, will be based on the actual performance results at the end of each respective performance period.

**Columns (b) and (c)**

Column (b) reflects the number of shares acquired upon the exercise of stock options during 2022 and column (c) reflects the value realized. The value realized is the difference in the market price over the exercise price on the exercise date.

**Columns (d) and (e)**

PSU grants made in 2020 were subject to a three-year performance period that ended on December 31, 2022. The award was earned at 189% of target. Column (d) includes the PSUs that were earned and associated DEUs, while column (e) reflects the value of the PSUs and associated DEUs, which is derived by multiplying the number of shares that vested by the market value of the underlying shares on December 30, 2022 ($71.41). The value shown in column (e) differs from the amounts shown in the CD&A, which reflects the market value on the trading date immediately preceding the date that the Compensation Committee made its decisions about PSU payouts (February 13, 2023).

► $66.79 for the RSUs and PRSUs that were granted in 2020 and vested 1/3 on February 11, 2022

► $66.79 for the PRSUs that were granted in 2021 and vested 1/3 on February 13, 2022 upon certification of the goal performance
 by the Compensation Committee

► $69.25 for the RSUs that were granted in 2021 and vested 1/3 on February 3, 2022

► $71.41 for the RSUs that were granted to Steve Kuczynski in 2018 and vested 20% on December 31, 2022

The Company provides retirement benefits from various plans to its employees, including the NEOs. The Company maintains different plans to address various legal and tax requirements, and different groups of employees.

● The SBP-P provides highly-paid employees any benefits that the Pension Plan cannot pay due to statutory pay or benefit limits. The SBP-P benefits are generally payable in 10 annual installments.

● The SERP, closed to new hires and promotions since January 1, 2016, provides highly-paid employees additional benefits that the Pension Plan and SBP-P would pay if the 1.7% offset formula of the Final Average Earnings Formula reflected a portion of annual performance-based pay. The SERP benefits are payable in 10 annual installments.

● Supplemental retirement agreements (SRAs) are entered into with certain employees that were initially employed by a Company affiliate in the middle of their careers, and provide credit for years of employment prior to employment with the Company or one of its affiliates. The SRA benefits are payable in 10 annual installments.

**Executive Compensation Tables**

In 2022, all NEOs participated in or had a benefit under the Pension Plan and the SBP-P. All NEOs had Pension Plan benefits under the Final Average Earnings Formula and participated in or had a benefit under the SERP. The Company has entered into an SRA with Mr. Womack providing an additional eight years of benefits. The Company has also entered into an SRA with Mr. Crosswhite providing an additional fifteen years of benefits. Additional details of these plans are described in the Benefit Plan Summary in Appendix B beginning on page 129. The table above reflects the present value of benefits accrued by each of the NEOs from the applicable plans or agreement.

Compensation used for determining pension benefits under the Pension Plan, SBP-P, SERP, and SRA generally includes only salary and annual cash incentives. The amounts reflected for each plan represent the present value of the maximum benefit payable under the applicable plan or agreement. In some cases, the payments may be reduced for early retirement or by benefits paid by other Southern Company-sponsored retirement plans, statutory payments or Social Security. The Company generally does not grant additional years of service, and no NEO has been credited with additional years of benefit service other than the SRAs entered into with Mr. Womack and Mr. Crosswhite.

The figures above reflect an assumption that each NEO continues to live at least until the earliest age at which an unreduced benefit is payable. The discount rate assumption used by the Company in calculating the present value of accumulated benefits was 5.26% for the Pension Plan and 5.10% for the SBP-P, the SERP, and Mr. Womack's and Mr. Crosswhite's SRA.

**Pension Benefit Assumptions**

The following assumptions were used in the present value calculations for all pension benefits:

► Discount rate — 5.26% Pension Plan and 5.10% supplemental plans (SBP-P, SERP and SRA) as of December
 31, 2022

► Retirement date – Earliest unreduced retirement age (age 65) or age as of December 31, 2022 if executive is older
 or retired

► Mortality after normal retirement — PRIA RP-2012 mortality tables with Aon custom projection scale (Endemic mortality)

► Mortality, withdrawal, disability and retirement rates prior to normal retirement — None

► Annual performance-based compensation earned but unpaid as of the measurement date 114% (Mr.
Fanning only) or 155% (all other NEOs) of target opportunity percentages times base rate of pay for year amount is earned

The plans utilize a different method of calculating actuarial present value for the purpose of a determining a lump sum, if any. The Pension Plan's benefit formulas produce amounts payable monthly over a participant's post-retirement lifetime. At retirement, plan participants can choose to receive their benefits from various forms of payment. All forms pay benefits monthly over the lifetime of the retiree or the joint lifetimes of the retiree and a beneficiary. Additional details on these retirement plans are described in the Benefit Plan Summary in Appendix B beginning on page 129.

The Company provides:

► The DCP which allows participants to defer part
 of their salary and PPP as well as applicable taxes on a voluntary basis and

► The SBP which makes participants whole when the Company matching
 contribution under the ESP is restricted by statutory limitations.

The amounts reported in this column also were reported in the All Other Compensation column in the Summary Compensation Table.

**Executive Compensation Tables**

**Column (b)**

This column reports the actual amounts of compensation deferred under the DCP by each NEO in 2022. The amount of salary deferred by the NEOs, if any, is included in the Salary column in the Summary Compensation Table. The amounts of performance-based compensation deferred in 2022 were the amounts that were earned as of December 31, 2021 but were not payable until the first quarter of 2022. These amounts are not reflected in the Summary Compensation Table because that table reports performance-based compensation that was earned in 2022 but not payable until early 2023.

**Column (c)**

This column reflects employer contributions under the SBP and DCP.

**Column (d)**

This column reports earnings or losses under the SBP and DCP on (1) compensation the NEOs elected to defer, (2) employer contributions, and (3) prior earnings attributable to each accruing during 2022.

**Column (f)**

This column includes amounts that were deferred under the DCP and contributions under the SBP in prior years and reported as compensation in the Summary Compensation Table through 2021: (i) Mr. Fanning: $9,879,292, (ii) Mr. Tucker: $454,209, (iii) Mr. Womack: $5,536,070, (iv) Mr. Kuczynski: $408,796, and (v) Mr. Crosswhite: $1,444,907.

**Potential Payments Upon Termination or Change in Control**

This section describes and estimates payments that could be made to the NEOs serving as of December 30, 2022 (the last business day of the 2022 fiscal year) under different termination and change-in-control events. The estimated payments would be made under the terms of Southern Company's compensation and benefit program or the change-in-control severance program. Mr. Crosswhite retired effective December 31, 2022 so the disclosure below describes the payments and benefits that he actually received upon retirement.

All of the NEOs are participants in the Severance Plan and the Benefits Protection Plan. As previously disclosed, the Company restated its change-in-control related compensation plans, including the Severance Plan and Benefits Protection Plan, effective August 15, 2022. To the extent not disclosed herein, refer to the Company's 2022 proxy statement for a summary of the terms of such plans prior to the restatements. The amount of potential payments is calculated as if the triggering events occurred as of December 30, 2022 and assumes that the price of common stock is the closing market price on December 30, 2022.

Description of Termination and Change-in-Control Events

The following charts and narratives list different types of termination and change-in-control events that can affect the treatment of payments under the compensation and benefit programs. No payments are made under the Severance Plan unless, within two years of the change in control, the NEO is involuntarily terminated not for cause or voluntarily terminates for good reason.

Traditional Termination Events

► Retirement — Termination of NEO who is
 at least 50 years old and has at least 10 years of credited service, whether voluntary or involuntary not for cause.

► Lay Off — Involuntary termination of NEO who is not retirement-eligible
 not for cause.

► Resignation
— Voluntary termination of NEO who is not retirement-eligible.

► Involuntary Termination — Involuntary termination of NEO
 for cause, whether or not retirement-eligible. Cause includes willful failure to perform duties and willful misconduct, such
 as violation of the Company's Drug and Alcohol Policy.

► Death or Disability — Termination of NEO due to death or
 disability.

**Change-in-Control-Related Events**

At the Company or the subsidiary company level:

► Company Change in Control — Generally,
 acquisition by an unrelated entity of 20% or more of the Company's common stock, majority turnover of the Board, the
 Company's consummation of a corporate transaction with an unrelated entity or the sale of substantially all of the assets
 of the Company that results in a substantial change in ownership or leadership (including where the Company's stockholders
 own less than 65% of the surviving entity), or the approval by the Company's stockholders of a complete liquidation
 or dissolution.

► Subsidiary Company Change in Control — Generally, acquisition
 by an unrelated entity of 50% or more of the stock of one of the Company's designated subsidiaries, consummation of
 a merger of a designated subsidiary with another entity and the Company does not control the surviving company, or the sale
 of substantially all of the assets of a designated subsidiary to an unrelated entity.

At the employee level:

► Involuntary Change-in-Control Termination or
 Voluntary Change-in-Control Termination for Good Reason — Within two years of a change in control, employment is terminated
 other than for cause or the employee voluntarily terminates for good reason. Good reason for voluntary termination within
 two years of a change in control is generally satisfied when there is a material reduction in the aggregate amount of salary,
 PPP and LTI; relocation of over 50 miles; a material diminution in title, duties and status; or a material reduction in employee
 benefits.

The following chart describes the treatment of different pay and benefit elements in connection with the Traditional Termination Events as described above, except the pension plans. The benefits payable under the Pension Plan and Supplemental Plans in connection with the Traditional Termination Events are described in the Benefit Plan Summary in Appendix B beginning on page 129.

<sup>\*</sup> All equity awards held by NEOs as of December 30, 2022 were granted prior to August 15, 2022 and as a result, are subject to the terms of the Benefits Protection Plan and Severance Plan as in effect prior to the recent restatement. Treatment of equity awards granted on or after August 15, 2022 upon a Traditional Termination Event or CIC is described below.

**DCP, SBP, SBP-P, and SERP**

Upon the NEO's death or disability, amounts that were deferred under the DCP or SBP may be paid in lump sum at the discretion of the Company's Benefit Administration Committee. Upon a separation from service within two years following a CIC, benefits deferred under the DCP or SBP on or after January 1, 2005 are generally payable in lump sum.

The benefit accrued under the SERP and SBP-P as of a CIC vests upon a Company CIC and for impacted subsidiary employees, upon a Subsidiary CIC. Upon a separation from service within two years following a CIC, benefits accrued under the SBP-P and SERP as of the NEO's separation from service are generally payable in lump sum.

**Executive Compensation Tables**

**Potential Payments**

This section describes and estimates payments that would become payable to the NEOs upon a termination or change in control as of December 30, 2022.

Pension Benefits

There are no enhancements to the benefits accrued by NEOs under the Pension Plan, the SBP-P, the SERP or the SRA upon the occurrence of the Traditional Termination Events. Further, there are also no enhancements to the benefits accrued by the Pension Plan upon the occurrence of a Change in Control.

There are no additional benefits accrued under the SBP-P, the SERP or the SRA upon a Change in Control. The SBP-P, SERP, and SRA benefits accrued through the date of a Change in Control that would otherwise be payable as 10 annual installments convert to a single lump sum payment. The amounts shown below reflect the value of the lump sum acceleration of these annual installments under the SBP-P, the SERP and the SRA for the NEOs, other than Mr. Crosswhite, upon a Change of Control effective as of December 31, 2022. If an NEO designates a non-spouse beneficiary, then the amount payable is 50% of the amount shown.

The amounts in this chart differ from the pension values shown in the Summary Compensation Table and the Pension Benefits table. Those tables show the present values of all the benefit amounts anticipated to be paid over the lifetimes of the NEOs and their beneficiaries. Those plans are described in the notes following the Pension Benefits.

The pension benefit amounts in the tables above were calculated as of December 30, 2022 assuming payments would begin as soon as possible under the terms of the plans. Accordingly, appropriate early retirement reductions were applied. Any unpaid annual performance-based compensation was assumed to be paid at 114% of the target level for Mr. Fanning and 155% of the target level for all other NEOs. Pension Plan benefits were calculated assuming each NEO chose a single life annuity form of payment, because that results in the greatest monthly benefit. The single sum values were based on a 1.94% discount rate for the Final Average Earnings Formula for accruals for 2022 and beyond, and the SBP-P calculations are based on ten annual installments.

**Annual Performance Pay Program**

The amount payable in the event of a Company Change in Control (assuming the program is terminated) or a Subsidiary Company Change in Control is the greater of target or the three-year historical average payout at the applicable business unit. Because the three-year historical average payouts for 2020-2022 were above the target level for all of the NEOs, the amount that would have been payable was the three-year historical average payout at the applicable business unit.

**Stock Options, PSUs, PRSUs and RSUs (Equity Awards)**

Equity Awards issued prior to December 31, 2022 would be treated as described in the narratives and charts above. However, this paragraph describes the potential treatment of Equity Awards granted on or after August 15, 2022. If a Company Change in Control occurs and no replacement award is issued, then all Equity Awards vest and PSUs vest at the greater of target or projected actual performance. If a Subsidiary Change in Control occurs, then all Equity Awards held by NEOs employed by the applicable subsidiary (and who cease employment with Southern and its affiliates) vest and their PSUs vest at target. In addition, if there is an Involuntary Change-in-Control Termination or Voluntary Change-in-Control Termination for Good Reason, then any replacement award issued vests and those awards subject to performance goals vest at the greater of target or projected actual performance.

The chart below shows the number of stock options for which vesting would be accelerated and the amount that would be payable if there were no conversion to the surviving company's stock options. It also shows the number and value of PSUs, PRSUs and RSUs that would be paid. For stock options, the value is the excess of the exercise price and the closing price of common stock on December 30, 2022. The value of PSUs, PRSUs, and RSUs is calculated using the closing price of common stock on December 30, 2022.

Healthcare Benefits

All of the NEOs were retirement-eligible as of December 30, 2022. Benefits are provided to retirees, and there is no incremental payment associated with the termination or change-in-control events, except in the case of a change-in-control-related termination, as described in the Change-in-Control-Related Events chart.

Financial Planning Perquisite

An additional year of the financial planning perquisite, which is set at a maximum of $20,000 per year for Mr. Fanning and $15,000 per year for all other NEOs, will be provided after retirement for retirement-eligible NEOs.

There are no other perquisites provided to the NEOs under any of the traditional termination or change-in-control-related events.

Severance Benefits

The Severance Plan provides severance benefits, including outplacement services, if within two years of a change in control the NEO is involuntarily terminated not for cause or voluntarily terminates for good reason. The severance benefits are not paid unless the NEO releases any claims the NEO may have against the employing company.

► The
 severance payment for Mr. Fanning is three times the sum of base salary and PPP opportunity (either at target or, if greater,
 paid out based on the average achievement from the three prior fiscal years) and two times that sum for the other NEOs.

► The
 estimated cost of providing the six months of outplacement services is $6,000 per NEO.

► If
 any portion of the severance amount constitutes an "excess parachute payment" under Section 280G of the tax code
 and is therefore subject to an excise tax, the severance amount will be reduced by an amount sufficient to avoid the application
 of the excise tax. Excise tax gross-ups will not be provided on change-in-control severance payments.

The table below estimates the severance payments that would be made to the NEOs if they were terminated as of December 31, 2022 in connection with a change in control.

**Executive Compensation Tables**

NEO Retirement

Upon his retirement effective December 31, 2022, Mr. Crosswhite became entitled to the benefits reflected in the Pension Benefits at 2022 Fiscal Year-End and Nonqualified Deferred Compensation as of 2022 Fiscal Year-End tables set forth on pages 93 and 94, respectively. Mr. Crosswhite's 2022 PPP was paid as reflected in the Summary Compensation Table on page 87 and his 2021-2023 and 2022-2024 PRSUs and PSUs will be paid on the regularly applicable schedule, subject to satisfaction of the underlying performance objectives. Mr.Crosswhite began a six-month term serving as an independent consultant on January 1, 2023 as described further above at page 81.

**Equity Compensation Plan Information**

The following table provides information as of December 31, 2022 concerning shares of common stock authorized for issuance under the Company's equity compensation plans. As of December 31, 2022, other than as described below, no equity securities were authorized for issuance under equity compensation plans not approved by stockholders.

<sup>(1)</sup> Includes 1,001,416 shares issuable pursuant to outstanding options, which were issued under the 2011 Omnibus Plan. Also includes 3,286,537 full-value awards outstanding under the 2011 Omnibus Plan, the Outside Directors Stock Plan for The Southern Company, and the 2021 Omnibus Plan, including (a) 1,191,550 shares that may be issued pursuant to outstanding PSUs under the 2011 Omnibus Plan and (b) 1,174,270 shares that may be issued pursuant to outstanding PSUs under the 2021 Omnibus Plan, in each case, based on achievement of performance goals established by the Committee and assuming 100% of target PSUs will be earned.

<sup>(2)</sup> The weighted average exercise price is limited to outstanding options under the 2011 Omnibus Plan. The weighted average remaining contractual term of outstanding and exercisable options was approximately 10 months.

<sup>(3)</sup> Includes 27,327,044 shares that may be issued pursuant to future awards under the 2021 Omnibus Plan. Also includes 295,042 shares which may be issued pursuant to future awards under the Outside Directors Stock Plan for The Southern Company; however, the Company intends to issue future director equity compensation awards under the 2021 Omnibus Plan and does not intend to issue any further awards under this plan after June 2021.

**Pay Ratio Disclosure**

For 2022, we have calculated the CEO pay ratio to be 167 to 1. This ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records as of December 31, 2022 and the methodology described below.

► The change in pension value as shown in the Summary Compensation Table is not due to any changes or
 modifications to the existing program or plan formula.

► Traditional pension plans are extremely sensitive to interest rate changes, and changes to macroeconomic factors such
 as interest rates are outside of the Company's control.

We determined our median employee based on an analysis of all employees as of December 31, 2022. We used total cash compensation as reported in Form W-2 for 2022 as our consistently applied compensation measure. We then applied a statistical sampling approach to identify employees who we expected were paid within a +/- 0.1% range above and below our estimated median total cash compensation value. From this group, we selected an employee who was reasonably representative of our median employee based on average employee tenure and age. We did not exclude any employees across the Southern Company system in identifying the median employee nor did we annualize compensation for any of our employees.

After identifying the median employee, as described below, we calculated the median employee's annual total compensation.

► The annual total compensation of the median employee, calculated in accordance with the Summary Compensation
 Table requirements and including amounts paid under nondiscriminatory health and welfare benefit plans, was $143,500. The
 median employee's annual total compensation is comprised of approximately $98,000 in salary, $16,900 in annual incentive
 payout, $4,900 in ESP matching contributions, $1,600 in perquisites and $22,100 in health and welfare equivalent benefits.
 The median employee is a Plant Operator for one of our state-regulated electric utilities.

► The CEO's annual total compensation was $24,028,770. This amount includes the total compensation amount included
 in the Summary Compensation Table and approximately $22,100 in nondiscriminatory health and welfare benefits.

**Executive Compensation Tables**

At December 31, 2022, the Southern Company system had over 27,000 employees across 34 states. We have an average tenure of approximately 15 years and a turnover rate of approximately 8.9% (5.2% when excluding retirements). Compensation for the majority of our employees includes variable compensation under programs similar to the annual incentive plan described in the CD&A. Notwithstanding collective bargaining agreements that make certain employees ineligible for the annual incentive program, more than 93% of the total employees are eligible for some type of annual incentive program (including commissions and sales incentive plans). In addition, most employees are eligible to participate in the defined contribution and pension plans described earlier in the executive compensation tables.

The SEC's rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their pay ratios.

**Pay Versus Performance Disclosure**

The following Pay Versus Performance table (PVP Table) provides SEC-required information about compensation for 2022 for the NEOs, as well as our named executive officers from our 2021 and 2020 proxy statements. The PVP Table also provides information about the results for certain measures of financial performance for both the Company and certain of our peers during those same covered years. In reviewing this information, there are a few important things we believe you should consider:

► We provide information in the PVP Table below about our Company absolute TSR results, absolute TSR
 results for a peer group of companies identified in the PVP Table and our GAAP net income results (collectively, the External
 Measures) during 2020 through 2022 (the Covered Years). We did not, however, base any compensation decisions for the PVP NEOs
 on, or link any PVP NEO compensation to, these particular External Measures because the External Measures were not metrics
 used in our short-term or LTI plans during the Covered Years. In addition, the peer group used for purposes of this PVP Table
 disclosure is substantially different than the comparator companies against which we evaluate relative TSR performance for
 our NEOs for purposes of our PSU awards, as described above on page 84 .

► For purposes of selecting the Company-Selected Measure, SEC guidance requires the use of a financial performance measure
 applicable to the most recently completed fiscal year, rather than a measure applicable over a multi-year performance period
 that includes the applicable fiscal year as the final year. We believe that relative TSR is the most important financial measure
 that demonstrates how we sought to link executive pay to performance for 2022. Our 2022 LTI plans utilize and apply significant
 weighting to the 3-year relative TSR performance measure for the Covered Years, as described above on page
 75 . As a result, we have determined that 1-year relative TSR should be designated as the "Company-Selected Measure"
 to be included in the column (i) of the PVP Table below.

**Executive Compensation Tables**

**Column (f)**

For each Covered Year, our absolute TSR was calculated based on the yearly percentage change in our cumulative TSR on our common stock, par value $5.00 per share, measured as the quotient of (a) the sum of (i) the cumulative amount of dividends for the period beginning with our closing stock price on the NYSE on December 31, 2019 through and including the last day of the covered year (each one-year, two-year and three-year periods, a "Measurement Period"), assuming dividend reinvestment, plus (ii) the difference between our closing stock price at the end versus the beginning of the Measurement Period, divided by (b) our closing share price at the beginning of the Measurement Period. Each of these yearly percentage changes was then applied to a deemed fixed investment of $100 at the beginning of each Measurement Period to produce the Covered Year-end values of such investment as of the end of 2022, 2021 and 2020, as applicable. Because Covered Years are presented in the table in reverse chronological order (from top to bottom), the table should be read from bottom to top for purposes of understanding cumulative returns over time.

**Column (g)**

The peer group utilized in the table above is the Philadelphia Utilities Sector Index (UTY). For each Covered Year, the peer group cumulative TSR was calculated based on a deemed fixed investment of $100 in the index through each Measurement Period, assuming dividend reinvestment.

**Column (i)**

For purposes of this PvP disclosure, our relative TSR is calculated substantially as described above in our Compensation Discussion and Analysis. See page 76 for more information on the calculation of relative TSR and the results shown in this Pay Versus Performance disclosure.

**Descriptions of Relationships Between CAP and Certain Financial Performance Measure Results**

The following charts provide, across the Covered Years, a clear description of the relationships between (1) our cumulative TSR and the cumulative TSR for the peer group reflected in the PVP Table above, (2) PEO CAP and the financial performance measures results set forth in columns (f), (h) and (i) of the PVP Table above, and (3) non-PEO NEO CAP and the financial performance measures results set forth in columns (f), (h) and (i) of the PVP Table above.

**Audit Committee Matters**

Audit Committee Report

The Audit Committee oversees the Company's financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for establishing and maintaining adequate internal controls over financial reporting, including disclosure controls and procedures, and for preparing the Company's consolidated financial statements.

In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed the audited consolidated financial statements of the Company and its subsidiaries and management's report on the Company's internal control over financial reporting in the 2022 annual report with management. The Audit Committee also reviews the Company's quarterly and annual reporting on Forms 10-Q and 10-K prior to filing with the SEC. The Audit Committee's review process includes discussions of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and estimates and the clarity of disclosures in the financial statements.

The independent registered public accounting firm is responsible for expressing opinions on the conformity of the consolidated financial statements with accounting principles generally accepted in the United States and the effectiveness of the Company's internal control over financial reporting with the criteria established in "Internal Control — Integrated Framework (2013)" issued by the Committee of Sponsoring Organizations of the Treadway Commission.

The Audit Committee has discussed with the independent registered public accounting firm the matters that are required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (PCAOB) and the SEC. In addition, in accordance with the rules of the PCAOB, the Audit Committee has discussed with and has received the written disclosures and letter from the independent registered public accounting firm regarding its independence from management and the Company. The Audit Committee also has considered whether the independent registered public accounting firm's provision of non-audit services to the Company is compatible with maintaining the firm's independence.

The Audit Committee discussed their overall audit scopes and plans separately with the Company's internal auditors and independent registered public accounting firm. The Audit Committee meets with the internal auditors and the independent registered public accounting firm, with and without management present, to discuss the results of their audits, evaluations by management and the independent registered public accounting firm of the Company's internal control over financial reporting and the overall quality of the Company's financial reporting. The Audit Committee also meets privately with the Company's compliance officer. The Audit Committee held nine meetings during 2022.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors (and the Board approved) that the audited consolidated financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 and filed with the SEC. The Audit Committee also reappointed Deloitte & Touche as the Company's independent registered public accounting firm for 2023. Stockholders are being asked to ratify that selection at the 2023 annual meeting.

Policy on Audit and Non-Audit Services

The Audit Committee adopted a Policy on Engagement of the Independent Auditor for Audit and Non-Audit Services that includes preapproval requirements for the audit and non-audit services provided by Deloitte & Touche. All of the services provided by Deloitte & Touche in fiscal years 2022 and 2021 and related fees were approved in advance by the Audit Committee.

► Under the policy, Deloitte & Touche delivers an annual engagement letter which provides a description
 of services anticipated to be rendered to the Company by Deloitte & Touche for the Audit Committee to approve. The Audit
 Committee's approval of Deloitte & Touche's annual engagement letter constitutes pre-approval of all services
 covered in the letter.

► In addition, under the policy, the Audit Committee has pre-approved the engagement of Deloitte & Touche to provide
 services related to the issuance of comfort letters and consents required for securities sales by the Company and services
 related to consultation on routine accounting and tax matters.

► The Audit Committee has delegated pre-approval authority to the Chair of the Audit Committee with respect to permissible
 services up to a limit of $50,000 per engagement. The Chair of the Audit Committee is required to report any pre-approval
 decisions at the next scheduled Audit Committee meeting.

ITEM 5

Approve an Amendment to the Restated Certificate of Incorporation to Reduce the Supermajority Vote Requirement to a Majority Vote

► The Board has determined that it is in the best interest of the Company and its
 stockholders to reduce the current two-thirds supermajority vote requirement in Article Eleventh of the Certificate to a majority
 vote.

► The Board proposed a similar amendment to the Certificate in several prior years and is putting
 the amendment up for vote again, consistent with the Board's and stockholders' support for a 2022 shareholder
 proposal from Mr. John Chevedden, an individual stockholder.

The Board recommends a vote **FOR** this proposal

**Current Provision in Certificate**

Article Eleventh of our Certificate currently requires the affirmative vote of the holders of at least two-thirds of our issued and outstanding common stock in order to:

► Authorize or create any class of stock preferred as to dividends or assets over the common stock or
 reclassify the common stock or change the issued shares of common stock into the same or a greater or less number of shares
 of common stock either with or without par value or reduce the par value of the common stock (collectively, Stock Changes);
 and

► Amend, alter, change or repeal Article Twelfth (with respect to preemptive rights), Article Eleventh (with respect to
 Stock Changes and amendments to the Certificate) or any provision contained in the Certificate or in any amendment thereto
 which provides for the vote of the holders of at least two-thirds of the issued and outstanding common stock.

**Proposed Amendment to Certificate**

The proposed amendment to Article Eleventh of the Certificate is as follows:

► Replace the two-thirds supermajority vote requirement with a requirement that the affirmative vote
 of a majority of the issued and outstanding shares of common stock is required to approve any Stock Change; and

► Remove the two-thirds supermajority vote requirement necessary to amend, alter, change or repeal certain provisions of
 the Certificate, as more fully described above, so that all amendments, alterations, changes or repeals of the Certificate
 require the affirmative vote of a majority of the issued and outstanding shares of the capital stock of the Company, which
 is the default voting standard for such actions under Delaware law.

The text of the proposed amendment to Article Eleventh of the Certificate, marked to show changes from the current Article Eleventh, is shown below. If the proposal is approved, it will become effective upon filing of a Certificate of Amendment with the Secretary of State of the State of Delaware, which we would make promptly after the annual meeting.

**Analysis of Provision**

A supermajority vote requirement like the one contained in the Certificate is intended to facilitate corporate governance stability and provide protection against self-interested action by large stockholders by requiring broad stockholder consensus to make certain fundamental changes. While such protection can be beneficial to stockholders, as corporate governance standards have evolved, many stockholders and commentators now view this provision as limiting the Board's accountability to stockholders and the ability of stockholders to effectively participate in corporate governance.

After considering the arguments in favor of and against the existing supermajority vote requirement, and based on feedback we have solicited from our stockholders on this topic over the years, the Board voted to propose and declare advisable, and to recommend to stockholders that they approve, an amendment to Article Eleventh of the Certificate to reduce the two-thirds supermajority vote requirement to a majority vote requirement to (1) effect any Stock Changes and (2) amend, alter, change or repeal certain provisions of the Certificate.

The Board cannot unilaterally remove the supermajority voting requirement from the Certificate as Delaware law requires stockholder approval for such an amendment to the Certificate.

**Approve Amendment to Certificate**

**Responsiveness to 2022 Shareholder Proposal on Simple Majority Vote**

Mr. Chevedden submitted a shareholder proposal for last year's annual meeting, similar to previous proposals he has submitted, which included the following resolution:

*RESOLVED, Shareholders request that our board take the necessary steps so that each voting requirement in our charter and bylaws (that is explicit or implicit due to default to state law) that calls for a greater than simple majority vote be replaced by a requirement for a majority of the votes cast for and against such proposals, or a simple majority in compliance with applicable laws.*

In the 2022 proxy statement, the Board supported the spirit of Mr. Chevedden's proposal and recommended that stockholders vote FOR the proposal because it agreed with what it believed to be the proposal's intended purpose.

We committed to putting up for vote in 2023 an amendment to our Certificate to eliminate the only remaining supermajority voting requirement in our governing documents if the shareholder proposal passed at the 2022 annual meeting. Because the proposal received 98% support at the meeting and we continue to believe this amendment would be in the best interests of our stockholders, we are following through on our commitment.

**Previous Proposals to Amend the Certificate**

We proposed a similar amendment to the Certificate to reduce the supermajority vote requirement to a majority vote in each of 2013, 2016, 2017, 2019 and 2021. The Board recommended that stockholders vote for the proposal to amend the Certificate in each year it has come up for vote.

In 2021, the most recent year this proposal came to vote, the proposal received over 98% support of the votes that were cast, representing over 63% of the issued and outstanding shares. Despite the strong support, the proposal did not achieve the stockholder vote necessary to pass (affirmative vote of at least 66 2/3% of the issued and outstanding shares).

In the years that we have proposed amending the Certificate to reduce the supermajority vote requirement to a majority vote, we have seen an increase in the affirmative vote of the issued and outstanding shares.

---

| | |
|:---|:---|
| **Year Submitted for Vote** | **Affirmative Vote of Issued and<br> Outstanding Shares** |
| 2021 | 63% |
| 2019 | 61% |
| 2017 | 61% |
| 2016 | 57% |
| 2013 | 51% |

---

In prior years, we have taken meaningful action – including engaging third-party proxy solicitors – in attempts to encourage a strong stockholder turnout. We believe the primary reason we have not received the required affirmative vote of two-thirds of our issued and outstanding shares is due to our large retail stockholder base, which typically returns a lower proportion of proxies than the Company's institutional stockholder base. Over time, there has been a decrease in the percentage of our outstanding shares that are beneficially held by retail, or individual, stockholders who purchase securities for their own personal account rather than for an organization. Correspondingly, we have seen an increase in the affirmative vote of the issued and outstanding shares supporting this proposal. This year, we have again engaged a leading third-party proxy solicitor to assist with stockholder turnout.

**Text of Proposed Amendment to the Certificate**

The text of the proposed amendment to Article Eleventh of the Certificate, marked to show changes to the current Article Eleventh, is as follows:

ELEVENTH: The corporation reserves the right to increase or decrease its authorized capital stock, or any class or series thereof, or to reclassify the same, and to amend, alter, change or repeal any provision contained in the Certificate of Incorporation or in any amendment thereto, in the manner now or hereafter prescribed by law, and all rights conferred upon stockholders in said Certificate of Incorporation or any amendment thereto are granted subject to this reservation; provided, however, that the corporation shall not, unless authorized by the affirmative vote in favor thereof of the holders of at least two-thirds <u>a majority</u> of the issued and outstanding common stock of the corporation given at any annual meeting of stockholders or at any special meeting called for that purpose, (a) authorize or create any class of stock preferred as to dividends or assets over the common stock or reclassify the common stock or change the issued shares of common stock into the same or a greater or less number of shares of common stock either with or without par value or reduce the par value of the common stock, or (b) amend, alter, change or repeal [Intentionally Omitted], Article Twelfth, this provision or any provision contained in the Certificate of Incorporation or in any amendment thereto which provides for the vote of the holders of at least two-thirds of the issued and outstanding common stock.

**ITEM 6-8**

Vote on Three Stockholder Proposals

**X** The Board recommends a vote **AGAINST** each proposal

The following three proposals were submitted by stockholders. If the stockholder proponent of each proposal, or the proponent's representative, is present at the annual meeting in person and presents the proposal for a vote, then the proposal will be voted on at the meeting.

Following SEC rules, other than minor formatting changes, we are reprinting the proposals, graphics and supporting statements as they were submitted to us. We take no responsibility for them.

Upon oral or written request to the Corporate Secretary at the address listed on page 53, we will provide information about names, addresses and stockholdings of any co-sponsors of the proposals.

**Item 6: Simple Majority Vote**

*Mr. John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, California 90278, holder of at least 100 shares of Southern Company common stock, submitted the following proposal.*

**Proposal 6 – Simple Majority Vote**

![](so4109301-pre14ax112x2.jpg)

Shareholders request that our board take each step necessary so that each voting requirement in our charter and bylaws (that is explicit or implicit due to default to state law) that calls for a greater than simple majority vote be replaced by a requirement for a majority of the votes cast for and against such proposals, or a simple majority in compliance with applicable laws.

If necessary this means the closest standard to a majority of the votes cast for and against such proposals consistent with applicable laws. This includes any existing supermajority vote requirement that results from default to state law and can be subject to replacement. This proposal topic is particularly important because it was approved by 98% of The Southern Company voting shares in 2021 as a management proposal.

This 2023 proposal includes that the Board take all the steps necessary at its discretion to help ensure that the topic of this proposal is approved by the required of 67% of all outstanding shares including a commitment to hire a proxy solicitor to conduct an intensive campaign, a commitment to adjourn the annual meeting to obtain the votes required if necessary and to take a 2-year process if applicable to obtain the necessary shareholder vote turnout to adopt this proposal topic. This proposal does not restrict the Board from using a means to obtain the necessary vote that is not mentioned in this proposal.

For instance PPG Industries, Inc. (PPG) adjourned its annual meeting for weeks to obtain the necessary votes on this proposal topic in 2022 and Raytheon Technologies Corporation (RTX) announced a 2-year process to obtain shareholder approval of this proposal topic in its 2022 proxy.

This proposal includes that the Board make an EDGAR filing approximately 10-days before the annual meeting urging shareholders to vote in favor of a binding simple majority vote proposal like this proposal and explaining all the efforts the board has taken or will take to obtain the necessary vote and all the available efforts that the Board has not taken with an explanation for each available effort not taken. It is important to make an all-out effort now to obtain shareholder approval of this proposal topic in preference to the expense of conducting failed votes on this important proposal topic every year into the foreseeable future.

Extraordinary measures need to be taken to adopt this proposal topic because it won 98% approval from the shares that voted in 2021. However not enough shareholders cast ballots in 2021 and 3 earlier management "attempts" to obtain shareholder approval for this proposal topic. The Southern Company directors were negligent in not taking effective means to increase the low shareholder voting turnout.

With simple majority vote it will be less difficult to adopt improvements to the governance of The Southern Company. The principle of simple majority vote is a win for shareholders, the Board and management.

Please vote yes:

**Stockholder Proposals**

**Board's Recommendation and Statement**

**The Board has carefully considered this proposal and recommends that you vote AGAINST the proposal for the reasons described below.**

The Board has carefully considered this proposal and concluded that its adoption is unnecessary in light of the simple majority vote standard that we are asking stockholders to adopt in Item 5. Moreover, given the vague phrasing of this proposal, it could be interpreted to suggest that the Company should take additional actions beyond those necessary to eliminate the last supermajority requirement in our governing documents, which we believe would run counter to our stockholders' best interests. Finally, we believe that this proposal's demands to take "extraordinary measures" to mobilize an uncertain stockholder turnout is not a prudent use of stockholder capital. Accordingly, the Board believes that this proposal is not in the best interests of Southern stockholders and recommends that stockholders vote against this proposal.

***The Company's own proposal in Item 5 will have the effect of eliminating the only remaining supermajority voting requirement in our governing documents, making this proposal unnecessary.***

As described in Item 5 on page 108, our governing documents contain only one supermajority voting requirement, Article Eleventh of the Certificate. Our By-Laws do not contain any supermajority voting requirements. As described in the Company's proposal in Item 5, the Board cannot unilaterally remove the supermajority voting requirement from our Certificate as Delaware law requires stockholders' approval. For this reason, the Board has approved and recommended that stockholders approve the amendment to our Certificate to eliminate the last remaining supermajority voting requirement, as described in Item 5.

We believe that the Company's proposal in Item 5 and its accompanying amendment to the Certificate are drafted in a manner that is consistent with market practice and stockholder feedback we have received on this topic. If we receive stockholder approval of the Company's proposal in Item 5, the Certificate amendment will be filed promptly with the State of Delaware and there will be no remaining supermajority voting standards in our governing documents.

***This proposal is vague and could be interpreted to suggest that the Company should take additional actions beyond those necessary or in line with market practice to eliminate the last remaining supermajority voting requirement in our governing documents.***

While we agree with this proposal's stated purpose of eliminating supermajority voting requirements in the Company's organizational documents, the Board took special notice that this proposal also asks for eliminating "any existing supermajority vote requirement that results from default to state law and can be subject to replacement." This language appears to be more expansive than the Company's own proposal in Item 5, although its precise meaning is not clarified elsewhere in this proposal.

For example, under Delaware law, certain stockholders are restricted from engaging in a business combination with a company for a period of three years after buying more than 15% of the company's stock unless certain criteria are met, including the affirmative vote of at least 662/3% of the outstanding voting stock which is not owned by the interested stockholder. This state law restriction does not apply if the company's board of directors approves the business combination, and is intended to protect companies against abusive takeover practices.

Delaware law provides Delaware corporations with the ability to "opt out" of this provision. We are uncertain if this proposal is requesting that the Board take this (or any other specific) action, but we believe that this proposal is vague and confusing enough that it could be one interpretation. Furthermore, none of the Company's Delaware-incorporated peer companies have opted out of the Delaware law default, and only approximately 10% of Delaware-incorporated S&P 500 companies have done so. To that end, our Board believes that "opting out" of the Delaware state law provision described above would neither follow market practice nor would it be in the best interests of stockholders or the Company.

During our extensive, multi-year stockholder engagement on the topic of supermajority voting provisions, stockholders have been clear that they support the elimination of the last supermajority vote requirement in the Certificate, which can be accomplished through support for the Company's proposal in Item 5 without introducing the ambiguity that would arise with the approval of this proposal.

**Stockholder Proposals**

***We disagree with this proposal's characterization of our attempts to increase stockholder voting turnout as well as its demands to devote "extraordinary" resources to achieving its purpose.***

At five stockholder meetings in the last decade (2013, 2016, 2017, 2019 and 2021), we submitted a proposal seeking stockholders' approval to eliminate the last remaining supermajority voting requirement in our organizational documents. Each time, the Board approved and recommended that stockholders approve the appropriate amendment to our Certificate. Each time, the proposed amendment received stockholder support of over 90% of votes cast but failed to receive the required vote of two-thirds of our outstanding shares.

We believe the primary reason we have not received the required affirmative vote of two-thirds of outstanding shares is due to our large retail stockholder base, which typically returns a lower proportion of proxies than the Company's institutional stockholder base. As noted in the analysis in the Company's proposal in Item 5, in the years that we have proposed amending the Certificate to reduce the supermajority vote requirement to a majority vote, we have seen an increase in the affirmative vote of the issued and outstanding shares.

---

| | |
|:---|:---|
| **Year Submitted for Vote** | **Affirmative Vote of Issued and<br> Outstanding Shares** |
| 2021 | 63% |
| 2019 | 61% |
| 2017 | 61% |
| 2016 | 57% |
| 2013 | 51% |

---

Over time, there has been a decrease in the percentage of our outstanding shares that are beneficially held by retail, or individual, stockholders who purchase securities for their own personal account rather than for an organization, and we have seen a corresponding increase in the affirmative vote of the issued and outstanding shares supporting the Company's proposals to amend the Certificate. We believe that the proposal's contention that the Company's "directors were negligent in not taking effective means to increase the low shareholder voting turnout" is false and inaccurate given our prior meaningful action – including engaging third-party proxy solicitors – to encourage a strong stockholder turnout.

This year, we have again engaged a leading third-party proxy solicitor to help us encourage a strong stockholder turnout. However, the costs to the Company to solicit votes from our retail stockholders are very significant and, even with these additional expenditures, the Company may still fail to successfully solicit enough votes. We do not believe that committing at this time to spend millions of additional dollars of stockholder capital or committing to adjourn our annual meeting until we secure the required vote would be a prudent use of time or resources, particularly since the required vote is not guaranteed even with such efforts.

**X** The Board recommends a vote **AGAINST** the proposal.

**Item 7: Set Scope 3 GHG Targets**

*As You Sow, 2020 Milvia Street, Suite 500, Berkeley, California 94704, as representative of Handlery Hotels, Inc., 180 Geary Street, Suite 700, San Francisco, California 94108, holder of 1,543 shares of Southern Company common stock, and a co-filer, submitted the following proposal.*

<u>WHEREAS:</u> Energy utilities will play a critical role in achieving the Paris Agreement's goal of limiting global warming to 1.5 degrees Celsius ("1.5<sup>o</sup>C"). Electricity production accounts for 25% of national greenhouse gas emissions, and burning natural gas for heat in buildings accounts for approximately 10%.<sup>1</sup> In addition, significant upstream emissions are created from the production of the fossil fuels used in power production and heating buildings.<sup>2,3</sup> Finally, utilities provide energy to some of the most energy-intensive industries; reducing greenhouse gas ("GHG") emissions associated with energy production would significantly reduce such emissions.

The International Energy Agency's Net Zero Scenario sets forth a trajectory for achieving 1.5<sup>o</sup>C, requiring net zero emissions from power generation by 2035 in advanced economies and globally by 2040, while requiring a 40% reduction of emissions from the building sector by 2030.<sup>4</sup>

[**Table of Contents**](#toc1)

**Stockholder Proposals**

Southern Company has set net zero GHG reduction targets for its Scope 1 but not for its Scope 3 value- chain emissions.<sup>5</sup> Approximate 28% of the Company's total reported GHG footprint occurs from its value chain categories of upstream production of gas, downstream burning of gas by customers, and purchased power from the grid.<sup>6</sup> The percentage may be higher. Research has found that the Environmental Protection Agency's emissions factors for natural gas, on which many utilities' methane calculations rely, potentially underestimate supply chain methane emissions by 60%.<sup>7</sup>

Peer utilities are starting to address value-chain emissions in their GHG reduction goals. PSEG and NRG committed to set a net zero target through the Science Based Targets initiative, which requires utilities to address all material Scope 3 value-chain emissions.<sup>8</sup> Sempra,<sup>9</sup> Duke,<sup>10</sup> and Dominion<sup>11</sup> set net zero targets covering full Scope 3 value-chain emissions, while Xcel<sup>12</sup> and CMS<sup>13</sup> have expanded their net zero targets to include customer use of natural gas.

<u>BE IT RESOLVED:</u> Shareholders request the Board issue short and long-term targets aligned with the Paris Agreement's 1.5<sup>o</sup>C goal requiring Net Zero emissions by 2050 for the full range of its Scope 3 value chain GHG emissions.

<u>SUPPORTING STATEMENT:</u> Proponents suggest, at management discretion:

► Taking into consideration approaches used by
 advisory groups like the Science Based Targets initiative;

► Providing
a timeline for setting its short and long-term Scope 3 GHG reduction targets;

► Providing an enterprise-wide climate transition plan to achieve
 net zero Scope 3 emissions;

► Disclosing annual progress towards meeting its emissions reduction
 goals.

**Board's Recommendation and Statement**

**The Board has carefully considered this proposal and recommends that you vote AGAINST the proposal for the reasons described below.**

We share As You Sow's interest in reducing Southern's GHG emissions across the value chain to achieve a net zero GHG emissions future, consistent with our core principles of providing clean, safe, reliable and affordable energy to customers and communities, and we are already taking tangible action to reduce our Scope 3 emissions. We also believe that consistent and comparable Scope 3 emission disclosures will allow investors to better assess portfolio risks, and that consistent year-over-year reporting will facilitate the ability of investors to compare Southern's risk and climate contributions against other peer utilities. For the reasons set forth below, we believe setting reduction targets for our Scope 3 emissions at this time would be premature, not add meaningful information for stockholders unless and until more standardized reporting protocols for Scope 3 emissions, including related mitigation approaches, are widely adopted and instead only expose us to undue risk and distraction.

***We have a long-standing commitment to providing climate-related disclosure, including GHG reduction targets, measurement and reporting, which provide transparency into our strategy and performance.***

We demonstrate our support for the objectives of the Paris Agreement by actively advancing a net zero by 2050 goal for our Scope 1 emissions, as well as setting an interim target to achieve 50% Scope 1 emissions reduction by 2030 relative to 2007 levels. We provide regular qualitative and quantitative reporting on our progress toward meeting these goals, including detailed information on our fleet transition, retirement of coal units and additions of renewable and zero carbon generation, as well as describing our strategy for achieving our GHG reduction goals. Most recently, we have been transparent about expecting to sustainably achieve our 2030 Scope 1 emissions reduction target no later than 2025, a full five years early. Scope 1 emissions make up about 70% of our overall GHG emissions.

**Stockholder Proposals**

For several years, we have published disclosure that includes annual performance data on our GHG emissions and other key metrics. For example, we publish disclosure responsive to the recommendations of the Task Force on Climate-related Financial Disclosures and disclosure aligned with standards of the Sustainability Accounting Standards Board and the Edison Electric Institute/American Gas Association ESG/Sustainability Reporting Template. We also provide detailed information through the CDP Climate Change survey responses, for which we received an A- leadership score for our submissions in both in 2022 and 2021.

We have made significant advancements in recent years in disclosing our Scope 3 emissions, which represent about 30% of our overall GHG emissions.

► In 2022, Southern enhanced Scope 3 disclosures
 in its CDP Climate Change survey response by including estimates of all relevant, indirect Scope 3 emissions, including upstream
 emissions from Southern's natural gas supply chain, and by better aligning Southern's downstream Scope 3 natural
 gas emissions estimate with the GHG Protocol equity share approach.

► In 2022, Southern engaged in conversations with entities evaluating
 protocols for methane emissions disclosures to understand and evaluate reporting and quantification frameworks for estimating
 and disclosing methane emissions. As part of these efforts, Southern is a foundational sponsor of GTI Energy's Veritas
 effort to develop a standardized, science-based, technology-neutral approach to calculating and reporting methane emissions.

► In 2022, our Southern Company Gas subsidiary published a report
 from an outside consultant analyzing pathways for its natural gas distribution companies to reach net zero direct GHG emissions
 and analyzed pathways for reducing indirect GHG emissions from its natural gas supply chain and customer use of natural gas.

► In 2021, Southern engaged an outside consultant to evaluate methodologies
 for estimating indirect upstream Scope 3 GHG emissions from its natural gas supply chain based on analysis of estimated emissions
 from gas production, processing and transportation.

We have demonstrated a willingness to set GHG emissions targets and to consistently enhance our climate-related disclosure when this information would be decision-useful for stockholders and other stakeholders.

***Setting targets for Scope 3 emissions would be premature given concerns about a lack of standardization and accuracy within existing measurement methodologies and protocols for reporting Scope 3 emissions and related Scope 3 mitigation solutions.***

We believe that the methodologies behind measuring Scope 3 emissions and protocols for reporting Scope 3 emissions and related Scope 3 mitigation solutions are currently too unsettled to serve as a firm foundation for setting Scope 3 emission reduction goals with the rigor that our stockholders and other stakeholders expect from us.

► The Science-Based Targets initiative (SBTi),
 which is referred to in the proposal, is undertaking a multi-year process to develop guidance relevant to measuring certain
 methane emissions. In the interim, the SBTi has paused acceptance of commitments and validation of targets for certain natural
 gas activities until this guidance is finalized.

► The proposal also refers to emission factors from the Environmental
 Protection Agency (EPA) for quantifying natural gas emissions. A recent study led by Stanford University estimated that the
 amount of methane leaking from a prominent U.S. oil and gas producing region could be several times greater than the federal
 government estimates. Other studies have also identified wide ranges of uncertainty in emissions. Even within EPA, different
 emissions factors are used for the mandatory GHG reporting program and the GHG inventory program. This wide range of uncertainty
 could cause Southern, or any other purchaser of natural gas who sets a Scope 3 emissions goal based on the current, imprecise
 understanding of actual Scope 3 emissions, to be exposed to unnecessary risk while not providing meaningful additional information
 to investors.

► In September 2022, the World Resources Institute and World Business
 Council for Sustainable Development (WRI/ WBSCD) GHG Protocol, the global standard for how many companies (including Southern)
 measure, manage and report GHG emissions, released the draft Land Sector and Removals Guidance, which intends to provide clarity
 on the methods and data needed to account for and report GHG emissions and removals from land-based activities and technological
 carbon dioxide removal activities. The draft guidance is proposing changes to current GHG accounting methodology, and WRI/WBSCD
 has initiated a process to collect stakeholder input to understand the need, scope and potential approaches to inform updates
 or additional guidance related to GHG Protocol's Corporate Standard, Scope 2 Guidance, Scope 3 Standard, and Market-Based
 accounting approach.

**Stockholder Proposals**

Even among our peer utilities who are similarly working to quantify and disclose Scope 3 emissions, there is lack of consensus as to the best approach for measurement and reporting, meaning that data among companies may not be sufficiently comparable to be useful to investors.

Given concerns about the lack of consistency and accuracy in today's Scope 3 measurement methodologies and reporting, setting Scope 3 goals now would only expose Southern to unnecessary risk without adding meaningful disclosure for investors seeking to compare our performance with peer companies.

***We believe our resources are better spent supporting efforts to standardize methane emissions measurement, engaging in efforts to standardize reporting of Scope 3 emissions, including related mitigation approaches, and taking tangible action to reduce our actual Scope 3 emissions.***

Southern has taken a leadership role, along with other companies across the natural gas value chain, to advance the measurement and reporting of Scope 3 emissions. As we engage in these activities, we enhance our ability to quantify, evaluate and reduce GHG emissions. We believe Southern can have the most impact at this time by focusing on industry efforts to refine and standardize methane emissions measurement and Scope 3 reporting, enhanced disclosure and tangible, localized initiatives to reduce Scope 3 emissions.

► Southern is continuing its sponsorship of GTI
 Energy's Veritas effort to develop a widely accepted, standardized, science-based, technology-neutral approach to calculating
 and reporting methane emissions.

► Our Southern Company Gas subsidiary is a founding member of the
 ONE Future coalition, a group of natural gas companies working together to voluntarily reduce methane emissions across the
 natural gas value chain.

► Southern continued to expand its reporting in 2022 to include all
 relevant categories of its Scope 3 emissions, including methane and carbon emissions from the leakage and flaring of natural
 gas during upstream exploration, development, production, gathering and boosting, transmission and storage. Southern is committed
 to regular enhancement and updating of this reporting in the future.

► Southern is already employing a deliberate and disciplined approach
 to reduce Scope 3 emissions by focusing on upstream and downstream solutions which yield value for customers and other stakeholders.
 In 2022, we expanded our residential energy efficiency programs to include all our distribution companies. We have obtained
 regulatory support in some of our states to support renewable natural gas solutions for customers, and we are increasing purchases
 of responsibly sourced natural gas from producers who are limiting methane emissions. In addition, Southern is engaged in
 a wide range of initiatives to research hydrogen opportunities.

**Item 8: Issue Annual Report on Feasibility of Reaching Net Zero**

*Mr. Steven J. Milloy, 12309 Briarbush Lane, Potomac, Maryland 20854, holder of 67 shares of Southern Company common stock, submitted the following proposal.*

**Net Zero Report Card**

RESOLVED

Shareholders request that, beginning in 2023, Southern Company report annually to shareholders, omitting any confidential business information, about the company's actual progress toward, and ongoing feasibility of Southern Company's announced goal of reaching net- zero emissions of greenhouse gases by 2050.

**Stockholder Proposals**

SUPPORTING STATEMENT

In 2020, Southern Company adopted the goal of reaching net-zero greenhouse gas emissions by 2050 for the electricity it generates. *https://www.southerncompany.com/newsroom/clean-energy/plan-on-net-zero-carbon-emissions-goal.html*

But as Carlyle Group executive Megan Starr recently stated, "Net zero is so far off as not to be relevant without near-term targets." *https:// www.bloomberg.com/news/articles/2022-11-08/blackstone-pimco-stay-out-of-net-zero-group-even-after-concessions [bloomberg.com]*

The reality of net zero is likely much worse than that.

Since the United Nations began working on climate 30 years ago, manmade emissions of greenhouse gases have increased by about 50%. *https://ieep.eu/news/more-than-half-of-all-co2-emissions-since-1751-emitted-in-the-last-30-years [ieep.eu]*

The United Nations has stated that "global greenhouse gas emissions show no signs of peaking." *https://wedocs.unep.org/ bitstream/ handle/20.500.11822/26879/EGR2018_ESEN.pdf?sequence=10 [wedocs.unep.org]*

Because of real-world cost constraints, grid reliability requirements and technological limitations, it's not clear that any combination of wind, solar, batteries and other technologies can actually replace fossil fuel generation on a timeframe reasonably consistent with "net zero by 2050." There is no revolutionary greenhouse gas-free energy technology in the foreseeable future. Carbon offsets and carbon capture and sequestration technology are also unproven means of reducing greenhouse gas emissions on a utility scale.

Not surprisingly, no one has an actual workable, practical and realistic plan to reach net zero by 2050 – no utility or energy company, no public utility service commission, no grid operator, and no government regulatory agency.

The Electric Power Research Institute (EPRI), a utility industry research [sic] group to which Southern Company belongs, has recently admitted in a report that "clean electricity plus direct electrification and efficiency... are not sufficient by themselves to achieve net-zero economy-wide emissions." *https://lcri-netzero.epri.com [lcri-netzero.epri.com]*

Moreover, EPRI has not even examined whether ESG is even feasible in terms of supply chain constraints, and operational reliability and resiliency.

At best, corporate promises of net zero currently are pure fantasy. At worse, they are materially false and misleading.

If Southern Company management has a different view and believes that "net zero" by 2050 is not a false and misleading promise, it should report to shareholders its actual progress toward, and ongoing feasibility of attaining "net zero by 2050."

**Board's Recommendation and Statement**

**The Board has carefully considered this proposal and recommends that you vote AGAINST the proposal for the reasons described below.**

***The separate, specific report sought by this proposal would be duplicative and of no added value given our existing climate-related disclosure.***

We believe that the separate report sought by Mr. Milloy is unnecessary and would be a meaningful waste of corporate resources because Southern already discloses in great detail our progress toward net zero and concrete decarbonization initiatives, including our fleet transition plans, in numerous public disclosures as well as public regulatory filings. These include:

► Our 2021 Corporate Responsibility Executive
 Summary, which provides updates on our sustainability and climate efforts, including updated timelines for proposed coal-fired
 generation retirements/repowering and renewable energy additions, as well as our overall progress toward our 2030 and 2050
 decarbonization goals.

► Our Implementation and Action Toward Net Zero report, which describes
 our path toward net zero through several key elements: continued coal transition, utilization of natural gas to enable the
 fleet transition, further growth in our portfolio of zero-carbon resources, negative carbon solutions, enhanced energy efficiency
 initiatives and continued investment in R&D focused on clean energy technologies.

[**Table of Contents**](#toc1)

**Stockholder Proposals**

► Additional reporting on our sustainability website,
 including an ESG Data Table that provides annual GHG emissions data and a TCFD Content Index that outlines how our existing
 disclosures align with the climate-related risks and opportunities disclosure framework recommended by the Task Force on Climate-related
 Financial Disclosure.

► Our annual CDP Climate Change survery response, in which we provide
 extensive information regarding our emissions breakdown, targets and performance, and for which we received an A- score in
 both 2022 and 2021.

► The publicly available integrated resource plans submitted by our
 operating subsidiaries to their respective state regulators, including Georgia Power's 2022 IRP that sets forth the
 continuation of the transition of Georgia's energy resources, growing renewable resources, investments in reliability
 and resilience, and diverse, flexible customer programs that both economically benefit customers and lead to decarbonization.

***We believe that several of Mr. Milloy's supporting statements regarding the need for the requested report are inaccurate and potentially misleading.***

In the proposal's supporting statement, we believe that Mr. Milloy repeatedly mischaracterizes the climate-related regulatory and business landscape, as well as the opinions and views of industry experts. These mischaracterizations include:

► The supporting statement contends that "no
 one has an actual workable, practical and realistic plan to reach net zero by 2050 – no utility or energy company, no
 public utility service commission, no grid operator, and no government regulatory agency." We agree that there are challenges
 to achieving the goals of the Paris Agreement while also continuing to provide reliable and affordable energy to customers.
 However, implying that there is no realistic pathway to reaching net zero by 2050 is in direct conflict with the stated intentions
 of policymakers – including the current administration's stated goals for a zero-carbon electricity grid and a
 net zero carbon economy by 2050 – as well as the long list of peer utility companies that have likewise set, and regularly
 report on progress toward, their own net zero goals. To reach net zero by 2050, the Company is focused on, among other things,
 transitioning its generating fleet and making the necessary related investments in transmission and distribution grids, research
 and development on new technologies such as long-duration storage, carbon capture and utilization and advanced nuclear power,
 and advocating for sound energy policy. We are working constructively with our state regulators through the IRP processes
 in a manner that addresses affordability, reliability and resiliency for customers.

► The supporting statement further contends that the Electric Power
 Research Institute (EPRI) "recently admitted in a report that 'clean electricity plus direct electrification and
 efficiency... are not sufficient by themselves to achieve net-zero economy-wide emissions'". However, this is
 a mischaracterization of a statement from EPRI's Net-Zero 2050 report. EPRI's report, based on EPRI modeling and
 other research, discusses the need for further advancements in technologies, as well as reducing the cost of technologies,
 to achieve economy-wide net zero targets. This does not mean that the utility industry "can't attain net zero"
 – rather, it is a statement about economy-wide net zero, which covers activities and emissions sources outside of the
 electric sector.

► The supporting statement quotes Megan Starr, a Partner and Global
 Head of Impact at The Carlyle Group who works with Carlyle's portfolio companies in support of Carlyle's own firmwide
 net zero goals, as stating that "Net zero is so far off as not to be relevant without near-term targets". We disagree
 with the supporting statement's implication that long-term net zero targets are "pure fantasy", but we agree
 with the need for interim targets to demonstrate progress toward those long-term goals. For that reason, our existing disclosure
 also provide regular updates on our progress toward meeting our interim 2030 goal of 50% GHG emissions reduction relative
 to our 2007 benchmark. Notably, we expect to sustainably meet this goal no later than 2025, a full five years ahead of our
 goal.

***The apparent motivation for this proposal conflicts directly with Southern's existing business strategy as well as views expressed by the holders of a significant amount of our stock.***

Our conclusion from reviewing Mr. Milloy's request is not that Southern lacks disclosure on the details of our net zero strategy, but rather that Mr. Milloy disagrees with the strategy described in that disclosure. Southern welcomes the views and opinions of our stockholders, and extensively engages with stockholders on a variety of issues, including climate change and sustainability. During these engagements, we have received widespread support for our efforts to set targets and strategy aligned with a net zero by 2050 goal. Moreover, our targets and strategy are an output of extensive engagements with stakeholders – including our regulators, customers and communities – and reflect those stakeholders' perspectives.

**Stockholder Proposals**

We believe the underlying views of Mr. Milloy and his associated organizations, including the activist group Burn More Coal, conflict directly with the perspectives conveyed by the holders of a significant amount of our stock and other stakeholders and, accordingly, that preparing a separate report that is narrowly responsive to Mr. Milloy's views and suggests that we incorporate views of specific special-interest organizations, would not be an efficient use of resources and in the best interests of our stockholders.

**FAQs about Voting and the Annual Meeting**

---

| | |
|:---|:---|
|  | We encourage you to provide instructions to your broker or bank by voting your proxy so that your shares will be voted at the annual meeting in accordance with your wishes. |
| **Q** | **What is notice and access?** |
| **A** | The SEC's notice and access rule allows companies to deliver a Notice to stockholders in lieu of a paper copy of the proxy statement and annual report. The Notice provides instructions as to how stockholders can access the proxy statement and the annual report online, contains a listing of matters to be considered at the annual meeting and sets forth instructions as to how shares can be voted. Instructions for requesting a paper copy of the proxy statement and the annual report are set forth on the Notice. |
|  | Shares must be voted by internet, by phone or by completing and returning a proxy form. Shares cannot be voted by marking, writing on and/or returning the Notice. Any Notices that are returned will not be counted as votes. |
| **Q** | **What if I am a stockholder of record and do not specify a choice for a matter when returning a proxy form?** |
| **A** | Stockholders should specify their choice for each matter on the proxy form. If no specific instructions are given, proxies which are signed and returned will be voted in accordance with the Board's recommendations. |
| **Q** | **Can I change my vote?** |
| **A** | Yes. If you are a holder of record, you may change your vote by submitting a subsequent proxy, by written request received by the Corporate Secretary prior to the annual meeting or by attending the annual meeting and voting your shares in person. |
|  | If your shares are held through a broker, bank or other nominee, you must follow the instructions of your broker, bank or other nominee to revoke your voting instructions. |
| **Q** | **How are votes counted?** |
| **A** | Each share counts as one vote. |
| **Q** | **How many votes do you need to hold the annual meeting?** |
| **A** | A quorum is required to transact business at the annual meeting. Stockholders of record holding shares of stock constituting a majority of the shares entitled to be cast present virtually or represented by proxy constitutes a quorum. |
|  | Abstentions that are marked on the proxy form and broker non-votes are included for the purpose of determining a quorum, but shares that otherwise are not voted are not counted toward a quorum. |
| **Q** | **What are broker non-votes?** |
| **A** | Broker non-votes occur on a matter up for vote when a broker, bank or other holder of shares you own in "street name" is not permitted to vote on that particular matter without instructions from you, you do not give such instructions and the broker, bank or other nominee indicates on its proxy form, or otherwise notifies us, that it does not have authority to vote its shares on that matter. Whether a broker has authority to vote its shares on uninstructed matters is determined by NYSE rules. |

| **Q** | **How can stockholders include nominees in our 2024 proxy materials under the proxy access provisions of our By-Laws?** |
| **A** | Under our By-Laws, stockholders may nominate a person for election as a director at an annual meeting to be included in our proxy materials if the stockholders satisfy certain requirements. Generally, a stockholder, or group of up to 20 stockholders, must own, continuously for at least three years, at least 3% of our outstanding shares that are entitled to vote generally in the election of directors to be eligible to make a proxy access nomination. Stockholders who meet these requirements may nominate the greater of two directors or directors representing 20% of the directors in office as of the last day a notice may be delivered. |
|  | If a stockholder wants to nominate a director to be included in our proxy materials and form of proxy for the 2024 annual meeting of stockholders, the nomination must be submitted in writing to Corporate Secretary, Southern Company, 30 Ivan Allen Jr. Boulevard NW, Atlanta Georgia 30308 and received no earlier than November 16, 2023 and no later than December 16, 2023.

Notice should be addressed to Corporate Secretary, Southern Company, 30 Ivan Allen Jr. Boulevard NW, Atlanta, Georgia 30308. |
| **Q** | **How can stockholders make proposals or nominations at our 2024 annual meeting that will not be included in our proxy materials?** |
| **A** | Stockholders intending to present a proposal or make a nomination at our 2024 annual meeting that will not be included in our proxy materials must comply with the procedural requirements set forth in our By-Laws. |

|  | Assuming the 2024 annual meeting is held on schedule (so that the 2024 annual meeting is not more than 30 calendar days prior to and not more than 70 calendar days after the anniversary date of the 2023 annual meeting), then we must receive the written of a proposal or nomination no earlier than February 24, 2024 and no later than March 25, 2024. |
|  | Any notice that is mailed, faxed, emailed or otherwise delivered to anyone other than our Corporate Secretary must still be received by the Corporate Secretary no later than the relevant date specified above. |
|  | Our By-Laws require a nominee to deliver signed forms of a questionnaire, representation, and agreement that our Corporate Secretary will provide upon request.

**FAQs about Voting and the Annual Meeting**

---

| | |
|:---|:---|
| **Q** | **Could any additional proposals be raised at the annual meeting?** |
| **A** | As described above, our By-Laws require that a stockholder provide advance notice of any proposal or nomination to be brought at an annual meeting that is not included in our proxy materials. Notices by stockholders to bring proposals and nominations for the 2023 annual meeting of stockholders in accordance with our By-Laws had to be delivered to, or received by, the Company not earlier than February 24, 2023 or later than March 26, 2023. |
|  | The Company did not receive any notices from stockholders pursuant to our By-Laws to bring proposals or nominations before the annual meeting. Therefore, we do not know of any items, other than those referred to in the Notice that may properly come before the meeting. If any other business properly comes before the meeting, the proxy holder will vote on those matters in accordance with their best judgment. |

| **Q** | **Can I request a copy of the Company's 2022 Annual Report on Form 10-K?** |
| **A** | Yes. A copy of our 2022 Annual Report on Form 10-K including financial statements, as filed with the SEC, may be obtained without charge upon written request to the Corporate Secretary, Southern Company, 30 Ivan Allen Jr. Boulevard NW, Atlanta, Georgia 30308 or by sending a request to *shareholderservices@southernco.com*. You can also access the document on our website at *investor.southerncompany.com.* |
| **Q** | **Does the Company offer electronic delivery of proxy materials?** |
| **A** | Yes. Most stockholders can elect to receive an email that will provide an electronic link to the proxy statement, annual report and proxy voting site. Opting to receive your proxy materials online saves us the cost of producing and mailing documents. You may sign up for electronic delivery when you vote your proxy via the internet or by visiting *www.icsdelivery.com/so*. Once you enroll for electronic delivery, you will receive proxy materials electronically as long as your account remains active or until you cancel your enrollment. If you consent to electronic access, you will be responsible for your usual internet-related charges (e.g., online fees and telephone charges) in connection with electronic viewing and printing of the proxy statement and annual report. We will continue to distribute printed materials to stockholders who do not consent to access these materials electronically. |
| **Q** | **What is "householding?"** |
| **A** | Stockholders sharing a single address may receive only one copy of the proxy statement and annual report or the Notice, unless the transfer agent, broker, bank or other nominee has received contrary instructions from any owner at that address. This practice, known as householding, is designed to reduce printing and mailing costs. If a stockholder of record would like to either participate or cancel participation in householding, he or she may contact EQ Shareowner Services at 1-800-554-7626. If you own indirectly through a broker, bank or other nominee, please contact your financial institution. |
| **Q** | **Who is soliciting my proxy and who pays the expense of such solicitations?** |
| **A** | Your proxy is being solicited on behalf of the Board. |
|  | We pay the cost of soliciting proxies. We have retained Innisfree M&A Incorporated to assist with the solicitation of proxies for a fee of $25,000, plus additional fees for telephone and other solicitation of proxies or other services, if needed, and reimbursement of out-of-pocket expenses. Our officers or other employees may solicit proxies to have a larger representation at the meeting. None of these officers or other employees will receive any additional compensation for these services. Upon request, we will reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding solicitation material to the beneficial owners of the common stock. |

<sup>(1)</sup> Net income for the year ended December 31, 2022 includes impairment charges totaling $131 million pre-tax ($99 million after-tax) and other disposition impacts associated with the sales of two Southern Company Gas natural gas storage facilities. Net income for the year ended December 31, 2021 primarily includes: (i) a $93 million pre-tax ($99 million after-tax) gain associated with the termination of a leasehold interest in assets associated with two leveraged lease projects; (ii) $16 million of income tax benefits recognized as the result of another leveraged lease investment disposition; and (iii) a $121 million pre-tax ($92 million after-tax) gain on the sale of Sequent, as well as $85 million of additional tax expense due to the resulting changes in state apportionment rates. Net income for the year ended December 31, 2020 includes: (i) a $39 million pre-tax ($23 million after-tax) gain on the sale of Plant Mankato and (ii) a $22 million pre-tax ($16 million after-tax) gain on the sale of a natural gas storage facility.

**Appendix B - Benefit Plan Summary**

The following section provides information on compensation plans sponsored by the Company or its subsidiaries in which the Named Executives Officers participated during 2022.

**Retirement Plans – Pension and Supplemental Pension Plans**

**<u>Pension Plan</u>.** The Southern Company Pension Plan is a broad-based, funded tax-qualified defined benefit in which substantially all employees participate after one year of service. A participant's benefit formula in the Pension Plan is dependent upon the participant's date of hire.

<u>Vesting</u>. Normal retirement benefits become payable when participants attain age 65 and complete five years of participation. As of December 31, 2022, all of the NEOs were vested in their Pension Plan benefits. Participants who terminate employment after vesting can elect to have their pension benefits commence prior to age 65 provided they met the applicable early retirement age and service provisions. Early retirement Pension Plan benefits are reduced by actuarially determined factors, other than those benefits accrued under the Cash Balance Formula.

If a participant dies while actively employed and is vested in the Pension Plan as of the date of death, the participant's beneficiary is entitled to survivor benefits. If participants become totally disabled, periods that Social Security or employer-provided disability income benefits are paid will count as service for benefit calculation purposes. The crediting of this additional service ceases at the point a disabled participant elects to (a) commence retirement payments under the Final Average Earnings Formula or (b) qualifies for unreduced benefits under the Career Average Pay Formula. Outside of this extra service crediting, the normal Pension Plan provisions apply to disabled participants.

<u>Benefit Formula - Final Average Earnings</u>: The description below applies to each NEO, as participants hired by the Company before January 1, 2016.

► The plan benefit equals the greater of amounts
 computed using a 1.7% Offset Formula and a 1.25% Formula. The highest three years of pay out of a participant's last
 10 calendar years of service are averaged to derive a final average earnings.

► 1.7% Offset Formula: 1.7% of final average earnings
 (base pay only) times years of credited service less an offset related to Social Security benefits.

► 1.25% Formula: 1.25% of final average earnings (base play plus
 annual performance-based compensation earned) times years of credited service.

► Early retirement benefits become payable once
 plan participants have, during employment, attained age 50 and completed 10 years of credited service. Participants who retire
 early receive a 0.3% reduction for each month (3.6% for each year) prior to normal retirement that participants elect to have
 their benefit payments commence.

► As of December 31, 2022, all of the NEOs employed on that date
 and covered under the Final Average Earnings Formula were retirement- eligible.

► For NEOs covered under the Final Average Earnings Formula, the
 number of years of credited service is one year less than the number of years of employment.

<u>Payment of Benefits</u>*.* The Pension Plan's benefit formulas produce amounts payable monthly over a participant's post-retirement lifetime. At retirement, plan participants can choose to receive their benefits from various forms of payment. All forms pay benefits monthly over the lifetime of the retiree or the joint lifetimes of the retiree and a beneficiary. An actuarial reduction applies if a retiring participant chooses a payment form other than a single life annuity. It is assumed that male Pension Plan participants are two years older than their spouses.

<u>Limitations on Benefits</u>. Benefits are limited to a statutory maximum. The statutory limit restricts eligible compensation under the pension plan; the limit for 2022 was $305,000.

**<u>Supplemental Benefit Plan (Pension-Related) (SBP-P)</u>.** The SBP-P is an unfunded retirement plan that is not tax qualified. This plan makes highly-paid employees whole by (i) providing any benefits that the Pension Plan cannot pay due to the Limitations on Benefits described above and (ii) ignoring pay deferrals. When an SBP-P participant separates from

**Benefit Plan Summary**

service, vested monthly benefits provided by the benefit formulas described below are converted into a single sum value. If the separating participant is a "specified employee" under Section 409A of the Code, the first installment will be delayed for 6 months after the date of separation.

<u>Vesting</u>. The SBP-P's vesting and early retirement provisions mirror those of the Pension Plan. Its disability provisions mirror those of the Pension Plan but cease upon a participant's separation from service. In the event of a change in control, the benefits accrued under the SBP-P through the date of such change in control will vest and become non-forfeitable.

<u>Benefit Formula - Final Average Earnings</u>: The discount rate used in the single sum value calculation is based on the 30-year U.S. Treasury yields for the September preceding the calendar year of separation, but not more than 6%.

<u>Payment of Benefits - Final Average Earnings Formula</u>: Vested participants subject to the Final Average Earnings Formula terminating prior to becoming retirement eligible will be paid their single sum value as of September 1 following the calendar year of separation. If the terminating participant is retirement-eligible, the single sum value will be paid in 10 annual installments starting shortly after separation. The unpaid balance of a retiree's single sum will be credited with interest at the prime rate published in *The Wall Street Journal*.

If an SBP-P participant who is subject to the Final Average Earnings Formula dies while active after becoming vested in the Pension Plan, the beneficiary of the deceased participant will receive the single sum value in installments as soon as possible following death. The single sum value is calculated as if the participant had survived to age 50 and discounted back to the payment date (if earlier). Spouse beneficiaries receive 100% and non-spouse beneficiaries receive 50% of the single sum value.

**<u>Supplemental Executive Retirement Plan (SERP)</u>.** The SERP is an unfunded retirement plan that is not tax qualified. This plan provides highly-paid employees covered under the Final Average Earnings Formula additional benefits that the Pension Plan and the SBP-P would pay if the 1.7% offset formula calculations reflected a portion of annual performance-based compensation. The SERP was closed to new hires and future promotions effective January 1, 2016. The SERP's early retirement, survivor benefit and disability provisions mirror the SBP-P's provisions.

<u>Vesting</u>. SERP benefits do not vest until participants become eligible to retire, so no benefits are paid if a participant terminates prior to becoming retirement-eligible. The SERP benefits vest for participants who are not retirement-eligible upon a change in control.

<u>Benefit Formula</u>. To derive the SERP benefits, a final average pay is determined reflecting participants' base rates of pay and their annual performance-based compensation amounts, whether or not deferred, to the extent they exceed 15% of those base rates (ignoring statutory limits). This final average pay is used in the 1.7% offset formula to derive a gross benefit. The Pension Plan and the SBP-P benefits are subtracted from the gross benefit to calculate the SERP benefit.

**Retirement Plans – Employee Savings Plan**

**<u>Employee Savings Plan (ESP)</u>.** The ESP is a 401(k) defined contribution plan covering substantially all employees.

**<u>Supplemental Benefit Plan (SBP)</u>.** The SBP is a nonqualified deferred compensation plan where the Company can make contributions that are prohibited to be made under the ESP due to limits prescribed under the tax code. Under the Code, employer-matching contributions are prohibited under the ESP on employee contributions above stated limits and, if applicable, above legal limits set forth in the Code. The statutory limit for 2022 was $305,000. SBP contributions are treated as if invested in common stock and are payable in cash upon termination of employment in a lump sum or in up to 20 annual installments, at the election of the participant.

**Incentive Plans**

**<u>PPP</u>.** The PPP is an annual cash incentive award program that provides the opportunity to receive an annual cash award based on the achievement of predetermined corporate, business unit, and individual performance goals to substantially all employees. The PPP goals may include financial performance, such as EPS, net income, or other financial goals at the business unit or operating company, or operational performance, such as safety, operations, culture, and other goals specific to each business unit or operating company. A threshold, target, and maximum payout is set for each participant. PPP payouts usually occur in March in the year following the applicable performance year. See page 68 for additional information about the PPP, the goals applicable to the NEOs, and the 2022 payouts. The PPP is a component program of the 2021 Omnibus Plan.

**Benefit Plan Summary**

**<u>2021 Omnibus Plan</u>.** The Company's shareholders approved the 2021 Omnibus Plan in 2021 to provide cash awards and equity-based compensation to employees of the Southern Company system, non-employee directors of the Company and its subsidiaries, and certain other consultants or service providers. The use of shares of common stock as a component of our compensation program ensures that compensation is directly linked with long-term shareholder value creation and reward participants based on their continued service and/or performance. The following types of awards may be granted under the Omnibus Plan, as designated by the Compensation Committee: stock options, stock appreciation rights (SARs), restricted stock, RSUs, PSUs, PSUs, and cash-based awards. The Company currently has outstanding awards of stock options, RSUs, and PSUs, which are described below.

<u>Stock Options</u>. Stock options permit the holder to purchase shares of common stock at a specified price during specified time periods. The exercise price may not be less than the fair market value of common stock on the grant date. Fair market value is the closing price at which a share of Common Stock was trading on the grant date.

<u>RSUs</u>. RSUs provide an employee the opportunity to earn common stock, cash, or a combination thereof upon the achievement of predetermined performance- or time-based metrics. The Company's current compensation programs include PSUs as part of the annual LTI awards to eligible employees.

<u>PSUs</u>. PSUs provide an employee the opportunity to earn common stock if predetermined performance metrics are met for a predetermined performance period. The Company's current compensation programs include PSUs as part of the annual LTI awards to eligible employees.

**Other Plans**

**<u>Deferred Compensation Plan (DCP)</u>.** The DCP is an unfunded plan that permits participants to defer income as well as certain federal, state and local taxes until a specified date or their retirement, disability, death or other separation from service. Up to 50% of base salary and up to 100% of performance-based non-equity compensation may be deferred at the election of eligible employees.

Under the DCP, participants make an annual election to choose how much compensation to defer, when those deferrals will be paid and how distributions will be paid (in one to ten annual installments).

DCP participants have five notional investment options: the stock equivalent account, the prime equivalent account and three equivalent index fund accounts. Under the terms of the DCP, participants are permitted to transfer between investments at any time.

As of January 1, 2018, all of the NEOs were eligible to participate in the DCP. There is no enhancement or acceleration of payments under the DCP associated with termination or change-in-control events, other amounts deferred prior to 2005 which can be paid as a lump sum per the Benefit Administration Committee's discretion. The lump sums that would be payable are those that are reported in the Nonqualified Deferred Compensation table.
