In filing this Form SD, The Southern Company, a Delaware corporation (together with its subsidiaries, the “Company” or “Southern Company” or “we” or “us” or “our”), is relying on the “Updated Statement on the Effect of the Court of Appeals Decision on the Conflict Minerals Rule” issued on April 7, 2017, by the Division of Corporation Finance of the Securities and Exchange Commission (the “2017 SEC Statement”). As permitted by the 2017 SEC Statement, Southern Company is providing disclosure in this Form SD under the provisions of paragraphs (a) and (b) of this Item 1.01 but is not filing a Conflict Minerals Report or providing other disclosures under the provisions of paragraph (c) of this Item 1.01.

Rule 13p-1 requires disclosure of the information required by the applicable items of Form SD. Item 1.01 of Form SD requires the disclosure of certain information when a reporting company manufactures or contracts to manufacture products for which specified conflict minerals are necessary to the functionality or production of those products. The specified conflict minerals are columbite-tantalite (coltan), cassiterite, gold, and wolframite, including their derivatives, which are limited to tantalum, tin, and tungsten (the “Conflict Minerals”). The “Covered Countries” for the purposes of this Form SD are the Democratic Republic of the Congo and adjoining countries.

After conducting a good faith evaluation of our operations and products during the Reporting Period, Southern Company determined that PowerSecure, Inc., a Delaware corporation (“PowerSecure”), is the only Southern Company business unit that manufactures or contracts to manufacture products for which Conflict Minerals are necessary to the functionality or production of those products (“Covered Products”). Southern Company has designed and conducted a good faith reasonable country of origin inquiry (“RCOI”) to determine whether, during the Reporting Period, any necessary Conflict Minerals in the Covered Products of PowerSecure may have originated in a Covered Country and may not have come from recycled or scrap sources, and also conducted due diligence on the source and chain of custody of the necessary Conflict Minerals used in the Covered Products.

Southern Company is the parent company of three traditional electric operating companies, Southern Power Company, Southern Company Gas, PowerSecure, and other direct and indirect subsidiaries. The traditional electric operating companies – Alabama Power Company, Georgia Power Company, and Mississippi Power Company – are vertically integrated public utility companies providing electric service to retail customers in the states of Alabama, Georgia, and Mississippi in addition to wholesale customers in the Southeast. Southern Power Company is also an operating public utility company that develops, constructs, acquires, owns, and manages power generation assets, including renewable energy and battery energy storage projects, and sells electricity at market-based rates in the wholesale market. Southern Company Gas is an energy services holding company whose primary business is the distribution of natural

PowerSecure has adopted a Conflict Minerals Policy Statement with respect to Conflict Minerals. As stated in the Conflict Minerals Policy Statement, while PowerSecure does not source any Conflict Minerals from any of the Covered Countries directly, such Conflict Materials may exist in certain of the products, materials, and components that PowerSecure sources from its suppliers. PowerSecure is committed to working with its suppliers to responsibly source the materials and components that are used in its products.

To facilitate compliance with Rule 13p-1, suppliers of materials relating to Covered Products are requested to respond to information requests regarding the uses and sources of Conflict Minerals from the Covered Countries, including information about Conflict Minerals that are recycled or scrapped.

•Undertaking reasonable diligence within their supply chain to determine the source and chain of custody of their Conflict Minerals, including developing policies and systems to avoid the use of Conflict Minerals that directly or indirectly finance or benefit armed groups in the Covered Countries; and

Certain of PowerSecure’s operations manufacture, or contract to manufacture, products for which Conflict Minerals are necessary to the functionality or production of those products. The Covered Products that may have contained Conflict Minerals during the Reporting Period are set forth in the following table:


PowerSecure Business Unit	Associated Products that May Have Contained Conflict Minerals During the Reporting Period	Product Description
Distributed Generation	Interactive Distributed Generation Power Systems	Onsite power systems that provide backup power and load management
	NexGear Switchgear Systems	Advanced switchgear and electronic control systems

Energy Storage	Energy Storage Systems	Battery storage systems and controls

Although some of PowerSecure’s products are Covered Products that contain Conflict Minerals, PowerSecure does not purchase these minerals directly from smelters or refiners (collectively, “Smelters”). PowerSecure’s supply chain is complex, with many parties between the original sources of the Conflict Minerals and PowerSecure. PowerSecure purchases materials used in its products from a large network of suppliers, and some of those suppliers contribute necessary Conflict Minerals to its products. PowerSecure’s direct suppliers (and, in turn, their suppliers) are responsible for the procurement of most of the raw materials used in the Covered Products. Certain materials purchased by PowerSecure’s direct suppliers may come from processing facilities. As a result, the origin of Conflict Minerals used in PowerSecure’s Covered Products cannot be determined with certainty. Because PowerSecure does not purchase any Conflict Minerals directly from their original sources or processing facilities, in conducting the RCOI we must rely on the information provided by PowerSecure’s suppliers regarding the type and source of the Conflict Minerals contained in the materials they supply to PowerSecure.

We conducted a good faith RCOI regarding the necessary Conflict Minerals in the Covered Products. The RCOI was designed to determine whether any of those Conflict Minerals originated in the Covered Countries or were from recycled or scrap sources. The RCOI was based on the internationally recognized due diligence framework in the Organisation for Economic Co-operation and Development (the “OECD”) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas: Third Edition (2016), and related Supplements on Tin, Tantalum, Tungsten, and Gold (collectively, the “OECD Guidance”), specifically as it relates to PowerSecure’s position in the supply chain as a “downstream” company.

The RCOI was led by a cross-functional team that included business, legal, financial, and accounting leaders in our organization working with external responsible minerals consultants and external legal counsel. The RCOI process included reviewing internal data bases regarding product composition and raw materials purchases and was focused on conducting a supply chain survey with direct suppliers of the parts, products, equipment, components, and other materials that potentially contained Conflict Minerals incorporated into the Covered Products during the Reporting Period (“in-scope suppliers”) using the Conflict Minerals Reporting Template (the “CMRT”) developed by the Responsible Minerals Initiative (the “RMI”). The CMRT is the industry standard template developed to facilitate the transfer

of information through the supply chain regarding mineral country of origin and Smelters being utilized. Utilizing the CMRT, we conducted a supply chain survey of in-scope suppliers that requested information and confirmations related to whether any Conflict Minerals were present in the parts and materials supplied to PowerSecure and, if so, the countries of origin of those Conflict Minerals supplied or whether such Conflict Minerals were sourced from recycled or scrap materials.

For the in-scope suppliers that responded and provided Smelter data, we compared the Smelters identified by those suppliers to the list of facilities that have successfully completed an assessment against the applicable standard of the RMI Responsible Minerals Assurance Process (the “RMAP”), or an equivalent cross-recognized standard (such as the London Bullion Market Association or the Responsible Jewellery Council), which Smelters are designated “Conformant” by the RMI. Smelters that have committed to undergo an RMAP assessment are designated “Active” by the RMI. Under the RMAP, the RMI implements a risk-based assessment program for Smelter facilities in Conflict Minerals chains, and is a voluntary initiative in which an independent third party validates facility due diligence management systems in line with the OECD Guidance. However, not all Smelters identified in the RCOI participate in the RMAP, and even of those that are participating, not all have completed the RMAP assessment process. Moreover, some of the Smelters identified in the RCOI either are no longer operational or were misidentified and are not legitimate Smelters. Thus, we are unable to determine the conformant status of all of the Smelters identified in our RCOI.

The supplier communication process utilizing the CMRT included reaching out to all of the PowerSecure in-scope suppliers and engaging in an escalation process with in-scope suppliers who were non-responsive to either the survey or our requests for information or that provided incomplete or unclear responses. Further communications and engagement steps were taken with certain in-scope suppliers, seeking information about their own due diligence efforts, to ensure that the responses provided in response to the supply chain survey were understood and accurate. However, many of the responding in-scope suppliers utilized multiple sources for the same Conflict Mineral and thus were unable to identify specifically which of those multiple sources were utilized with respect to the particular Conflict Mineral actually supplied to PowerSecure.

We also conducted due diligence on the source and chain of custody of the necessary Conflict Minerals used in the Covered Products. These due diligence measures on the source and chain of custody of the Conflict Minerals in the Covered Products were designed to be in conformity, in all material respects, with the internationally recognized due diligence framework in the OECD Guidance. There was considerable overlap between the RCOI and this due diligence process.

Because PowerSecure is a downstream company in connection with its purchases of products that contain Conflict Minerals, the good faith RCOI, as well as the due diligence process to a large extent, were necessarily based on the data provided by the in-scope suppliers, and dependent upon those in-scope suppliers seeking and obtaining similar information within their supply chains to identify the original sources of the necessary Conflict Minerals supplied to PowerSecure in the Covered Products. However, while most of the in-scope suppliers responded to us, not all in-scope suppliers responded despite our repeated attempts to reach them, and some of the responding in-scope suppliers provided incomplete data or failed to provide any Smelter data. Moreover, many of the responding in-scope suppliers provided data at a company or distributor level rather than a product level, so we were

As a result, based on the information obtained from our good faith RCOI and due diligence process described herein, we do not have sufficient information to conclusively determine the countries of origin of all the necessary Conflict Minerals used in the Covered Products during the Reporting Period.
