Southern Company's $1.75 Billion Equity Units Offering and Convertible Note Repurchase Plan

Southern Company (NYSE:SO) disclosed plans on November 12, 2026, to sell 35 million equity units in a public offering at a stated amount of $50 per unit, for an aggregate stated amount of $1.75 billion. The company also expects to grant underwriters an overallotment option for an additional 5 million equity units, representing $250 million in additional aggregate stated amount, according to the announcement.

Each equity unit, as described in the filing, consists 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 with a principal amount of $1,000. The company stated it intends to use a portion of net proceeds to repurchase part of its Series 2024A 4.50% Convertible Senior Notes due June 15, 2027 (the "Existing Convertible Notes") through individually negotiated transactions with a limited number of holders, effected through one of the underwriters or its affiliate. The remaining net proceeds are intended to repay all or a portion of Southern Company's short-term indebtedness and for general corporate purposes, including investments in its subsidiaries.

The filing noted that Southern Company expects certain holders of the Existing Convertible Notes who sell their notes in a repurchase transaction may enter into or unwind various derivatives with respect to Southern Company's common stock, or purchase or sell shares in the market to hedge their exposure. The company stated 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." No assurance was given as to how much, if any, of the Existing Convertible Notes will be repurchased or on what terms. The announcement contains forward-looking statements that are subject to the company's cautionary language and a number of uncertainties described in the release.
