The Southern Company issued two privately placed series of convertible senior notes: $833,750,000 of 2.125% Series 2026A Convertible Senior Notes due December 15, 2027 and $1,897,500,000 of 3.50% Series 2026B Convertible Senior Notes due September 15, 2029, under its Senior Note Indenture with U.S. Bank Trust Company as trustee.
Both series are direct, unsecured and unsubordinated obligations, effectively subordinated to secured debt, and are not redeemable at the Company’s option. Holders may convert before final conversion periods only if stock-price or trading-price conditions are met or upon specified corporate events; later in each term, conversion is permitted at any time. The initial conversion rates are 9.5641 shares per $1,000 principal for the 2026A notes (initial conversion price $104.56) and 8.4389 shares per $1,000 for the 2026B notes (initial conversion price $118.50), with adjustments for certain events and potential conversion-rate increases upon a Make-Whole Fundamental Change.
Conversions will be settled in cash up to principal and, at the Company’s election, in cash, stock or a combination for any excess obligation. Upon a Fundamental Change (other than an Excluded Fundamental Change), holders can require repurchase at 100% of principal plus accrued interest, and Events of Default allow acceleration. The notes were sold to initial purchasers under Section 4(a)(2) of the Securities Act for resale under Rule 144A. The related conversion shares are unregistered; initially, up to 8,970,816 shares may be issued for the 2026A notes and up to 20,416,341 shares for the 2026B notes, based on an initial maximum conversion rate of 10.7596 shares per $1,000 principal.
