Southern Company announces offering of $1.25 billion in aggregate principal amount of Convertible Senior Notes due June 15, 2028

ATLANTA, May 20, 2025 /PRNewswire/ -- Southern Company (NYSE:SO) today announced an offering of $1.25 billion in aggregate principal amount of its convertible senior notes due June 15, 2028 (the "Convertible Notes") in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). In addition, Southern Company expects to grant the initial purchasers of the Convertible Notes an option to purchase, for settlement within a period of 13 days from, and including, the date the Convertible Notes are first issued, up to an additional $200 million in aggregate principal amount of the Convertible Notes.

Final terms of the Convertible Notes, including the initial conversion price, interest rate and certain other terms of the Convertible Notes, will be determined at the time of pricing. The Convertible Notes will be senior, unsecured obligations of Southern Company. Interest on the Convertible Notes will be paid semiannually. The Convertible Notes will mature on June 15, 2028, unless repurchased or converted in accordance with their terms prior to such date.

Prior to March 15, 2028, the Convertible Notes will be convertible only upon the occurrence of certain events and during certain periods. Thereafter, the Convertible Notes will be convertible at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, Southern Company will pay cash up to the aggregate principal amount of the Convertible Notes to be converted and pay or deliver, as the case may be, cash, shares of Southern Company's common stock, or a combination of cash and shares of common stock, at Southern Company's election, in respect of the remainder, if any, of Southern Company's conversion obligation in excess of the aggregate principal amount of the Convertible Notes being converted.

Southern Company intends to use a portion of the net proceeds from this offering to repurchase a portion of its Series 2023A 3.875% Convertible Senior Notes due December 15, 2025 (the "Series 2023A Convertible Notes") and its Series 2024A 4.50% Convertible Senior Notes due June 15, 2027 (together with the Series 2023A Convertible Notes, the "Existing Convertible Notes"), in each case through individually negotiated transactions with a limited number of holders thereof (each, a "note repurchase transaction"), effected through one of the initial purchasers of the Convertible Notes or its affiliate. Southern Company intends to use any remaining net proceeds to repay all or a portion of its outstanding commercial paper borrowings and for other general corporate purposes, which may include investment in its subsidiaries.

Contemporaneously with the pricing of the Convertible Notes, Southern Company expects to enter into one or more separate and privately negotiated transactions with a limited number of holders of the Existing Convertible Notes to use a portion of the proceeds of the offering to repurchase a portion of the Existing Convertible Notes on terms to be negotiated with each such holder. The terms of each note repurchase transaction are anticipated to be individually negotiated with each such holder of the Existing Convertible Notes and will depend on several factors, including the market price of Southern Company's common stock and the trading price of the applicable Existing Convertible Notes at the time of each such note repurchase transaction. Southern Company may also repurchase outstanding Existing Convertible Notes following the completion of the offering of the Convertible Notes. No assurance can be given as to how much, if any, of the Existing Convertible Notes will be repurchased or the terms on which they will be repurchased. 

Southern Company expects that holders of the Existing Convertible Notes that sell their Existing Convertible Notes to Southern Company in any note repurchase transaction may enter into or unwind various derivatives with respect to Southern Company's common stock and/or purchase or sell shares of Southern Company's common stock in the market to hedge their exposure in connection with these transactions. In particular, Southern Company expects that many holders of the Existing Convertible Notes employ a convertible arbitrage strategy with respect to the Existing Convertible Notes and have a short position with respect to Southern Company's common stock that they would close, through purchases of Southern Company's common stock and/or the entry into or unwind of economically equivalent derivatives transactions with respect to Southern Company's common stock, in connection with Southern Company's repurchase of their Existing Convertible Notes for cash. This activity could increase (or reduce the size of any decrease in) the market price of Southern Company's common stock or the Convertible Notes at that time and could result in a higher effective conversion price for the Convertible Notes.

This press release shall not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any sale of these securities in any jurisdiction in which such an offer, solicitation or sale would be unlawful. The offer and sale of the Convertible Notes and the shares of common stock issuable upon conversion of the Convertible Notes, if any, have not been, and will not be, registered under the Securities Act or the securities laws of any other jurisdiction, and the Convertible Notes and such shares of common stock may not be offered or sold without registration or an applicable exemption from registration requirements.
