Southern Company announces equity units offering

ATLANTA, Nov. 3, 2025 /PRNewswire/ -- Southern Company (NYSE: SO) today announced it plans to sell 35 million equity units in a public offering. Each equity unit will be issued in a stated amount of $50 ($1.75 billion aggregate stated amount) and will consist of a contract to purchase Southern Company common stock in the future and two 1/40 undivided beneficial ownership interests in remarketable senior notes each having a principal amount of $1,000. Southern Company expects to grant to the underwriters an option to purchase an additional 5 million equity units ($250 million aggregate stated amount) solely for the purpose of covering over-allotments.

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 underwriters for the equity units or its affiliate. Southern Company intends to use the remaining net proceeds from this offering (i) to repay all or a portion of Southern Company's short-term indebtedness, (ii) to repay at maturity all or a portion of the remaining outstanding Series 2023A Convertible Notes and (iii) to satisfy all or a portion of the redemption price in connection with the proposed redemption at par of the $1.25 billion aggregate principal amount of its Series 2020B 4.00% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due January 15, 2051. Any remaining net proceeds will be used for general corporate purposes, including investments in Southern Company's subsidiaries.

Contemporaneously with the pricing of the equity units, 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. Southern Company may also repurchase outstanding Existing Convertible Notes following the completion of the offering of the equity units. 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 equity units at that time and could result in a higher effective reference price for the stock purchase contract component of the equity units.
