Summary
Summary of the 8-K filed August 3, 2026. Cited figures are marked; the original filing is the authoritative source.
On August 3, 2026, Southern Company (NYSE: SO) announced proposed Rule 144A private offerings of two convertible senior note series: $650 milliona of convertible senior notes due December 15, 2027 and $1.5 billion of convertible senior notes due September 15, 2029.
The initial purchasers also have options for an additional $97.5 millionb (2027 notes) and $225 million (2029 notes), settleable within 13 days of first issuance. Pricing terms, including the initial conversion price and coupon, will be set at pricing and were not disclosed in this filing. The notes will be senior, unsecured obligations, with semiannual interest and conversion settlement that gives the company flexibility to pay principal in cash and the excess in cash, shares, or a combination.
A significant portion of the proceeds is earmarked to repurchase part of the company's existing convertible notes: the Series 2024A 4.50%c notes due June 2027 and the Series 2025A 3.25% notes due June 2028. These repurchases will be negotiated privately with select holders, and the company may buy back more after the offering closes. Remaining proceeds will repay short-term debt and fund general corporate purposes, including investments in subsidiaries.
The structure is a common liability-management approach that can lower the company's near-term refinancing risk and interest cost while extending maturities, though it adds potential future share dilution if the notes convert. Investors should note the potential market effects described in the release: holders of the existing notes who hedge through convertible arbitrage may buy shares or unwind short positions during repurchases, which could push the stock price up or reduce its decline and may raise the effective conversion prices of the new notes. The release is a notice of offerings only, not an offer to sell, and the securities are unregistered under the Securities Act.

03—Questions
Frequently Asked Questions
How much capital is Southern Company seeking through these offerings?
The base offerings total $2.15 billion: $650 million of 2027 convertible notes and $1.5 billion of 2029 convertible notes. If the initial purchasers exercise their options in full, total issuance could rise by up to $322.5 million, to about $2.47 billion.
What will the proceeds be used for?
A portion will repurchase part of the Series 2024A 4.50% convertible notes due 2027 and Series 2025A 3.25% convertible notes due 2028 in negotiated private transactions. The remaining proceeds will repay short-term debt and fund general corporate purposes, which may include investments in subsidiaries.
Could these notes dilute existing shareholders?
Possibly. Upon conversion, Southern Company may deliver common shares for the amount above principal, at its election. The filing does not disclose the conversion price, which will be set at pricing, so the scale of potential dilution cannot yet be quantified.
Could the repurchase activity affect Southern Company's stock price?
The company states that holders of the existing notes may hedge by buying shares or unwinding short positions during the repurchases. This could push the stock price up or limit declines and could raise the effective conversion prices of the new notes.
When can holders convert the new notes?
Before September 15, 2027 for the 2027 notes and June 15, 2029 for the 2029 notes, conversion is allowed only upon specified events and during specified periods. From those dates, holders can convert at any time until the second scheduled trading day before maturity.
