Southern Company Launches $2.15 Billion Convertible Debt Offering

The offering comprises $650 million in notes due December 15, 2027, and $1.5 billion in notes due September 15, 2029. Southern Company also expects to grant initial purchasers an option to acquire an additional $322.5 million in combined aggregate principal to cover overallotments. As unsecured obligations, the notes will pay interest semiannually, with final conversion prices and interest rates to be determined at the time of pricing.

Management intends to allocate a portion of the net proceeds toward repurchasing existing Series 2024A and Series 2025A convertible notes through privately negotiated transactions. Any remaining funds will be directed toward retiring short-term debt and supporting general corporate investments. The company noted that holders of existing notes who participate in these buybacks may adjust their market positions—potentially involving common stock purchases or derivative unwinds—which could influence Southern Company’s share price during the transaction window.
