Re: Registration Statement on Form S-3
Ladies and Gentlemen:
We have acted as counsel to The Southern Company (the “Company”) in connection with the above-referenced Registration Statement on Form S-3 (Registration Statement No. 333-253286) filed with the Securities and Exchange Commission (the “Commission”) on February 19, 2021 (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Act”), relating to $600,000,000 aggregate principal amount of the Company’s Series 2021C Floating Rate Senior Notes due May 10, 2023 (the “Notes”). The Notes will be issued pursuant to the Senior Note Indenture dated as of January 1, 2007 between the Company and Computershare Trust Company, N.A., as successor trustee (the “Trustee”), as heretofore supplemented and amended and as further supplemented by the Twenty-Fourth Supplemental Indenture dated as of November 10, 2021 (collectively, the “Indenture”).
We have examined the Registration Statement and the Indenture, which has been filed with the Commission as an exhibit to the Registration Statement. We have also examined the originals, or duplicates or certified or conformed copies, of such records, agreements, instruments and other documents and have made such other and further investigations as we have deemed relevant and necessary in connection with the opinions expressed herein. As to questions of fact material to this opinion, we have relied upon certificates of public officials and of officers and representatives of the Company.
In rendering the opinions set forth below, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies and the authenticity of the originals of such latter documents. We have also assumed that the Indenture is the valid and legally binding obligation of the Trustee.
Based upon the foregoing, and subject to the qualifications and limitations stated herein, we are of the opinion that the Notes are valid, binding and legal obligations of the Company, except as may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and to general principles of equity, whether considered in a proceeding at law or in equity. In rendering the foregoing opinion,
