# Southern Company prices $1.75B of equity units at 8.625%, forcing stock buys by 2029

> The units pay 8.625% a year and force buyers to take Southern stock by December 2029, funding a data-center build that Georgia's newly Democratic regulators were elected to police.

## $1.75 billion priced, closing Tuesday

[Southern Company](https://theinference.org/markets/companies/southern-company), the Atlanta holding company whose utilities serve about 9 million customers across the Southeast, [priced 35 million Series A equity units at a $50 stated amount](https://www.sec.gov/Archives/edgar/data/92122/000009212226000080/so2026equityunitsfinalpros.htm) on Thursday, November 12, $1.75 billion in all, settling Tuesday, November 17 [1][2]. Underwriters hold a 13-day option on 5 million more units, another $250 million [1].

Each unit is a bond wrapped around a promise. The holder collects 8.625% a year, 3.125% on the stock-purchase contract plus 5.50% on each of two remarketable note series, and owes $50 cash for common stock no later than December 15, 2029 [1]. The share count floats between 0.4326 and 0.5407 against a $92.47 pricing-day close and a $115.58 threshold 25% above it [1].

## The first $1.7 billion goes to debt

Net proceeds of $1.723 billion, $1.970 billion if the option is exercised in full, go first to debt: about $135.3 million retires roughly $125.8 million of 4.50% convertible notes due June 2027, leaving about $335 million of that stack, and the rest repays short-term borrowings of $776 million and funds subsidiaries [1].

## The plan grew to $100 billion; the cash flow did not

The scale behind it: a week earlier, executives [added about $4 billion to the $81 billion five-year plan from February](https://www.utilitydive.com/news/southern/874111/) and said it [could reach $100 billion](https://theinference.org/article/southern-company-earned-2-05-billion-as-georgia-s-new-commission-weighs-who-pays-for-its-100-billion-plan), resting on 21 gigawatts of signed large-load contracts, 7 more in late stages, and data-center usage up 59% year over year in the third quarter [3].

Southern's filing record since that call shows one other securities registration, [a November 10 prospectus for its dividend reinvestment plan](https://www.sec.gov/Archives/edgar/data/92122/000009212226000074/sosips-311x26.htm), so these units are the first money priced since the plan grew [5], a path [we charted when the shelf talk began](https://theinference.org/article/southern-company-can-sell-12-million-shares-at-any-moment-as-its-capital-plan-could-reach-100-billion).

The build already outruns the cash engine. Capital spending exceeded operating cash flow in eight of the last twelve quarters, by nearly $2 billion in the first quarter of 2026 [4].

*Quarterly capital expenditure versus operating cash flow, in USD billions, from Southern Company's quarterly SEC filings. The gap is what the equity units and new borrowings fund. [4][9]*

## Customers carry the ramp risk

Chief Financial Officer David Poroch told analysts the data-center contracts carry minimum bills covering at least 100% of the cost of serving them: "Before the kilowatt moves over the meter, we are recovering our costs embedded in those minimum bills" [3]. In Southern's telling, if a customer never ramps, the customer still pays.

The referees changed anyway. [Democrats won Georgia's governorship](https://www.gpb.org/news/2026/11/04/democrats-take-control-of-georgia-public-service-commission) and, with Peter Hubbard and Sheila Edwards taking seats, a 3-2 Public Service Commission majority that takes office in January, after campaigns animated by rate hikes and data-center growth [6]. Governor-elect Keisha Lance Bottoms has said she will call for a pause on data-center development [7]. Chief Executive Chris Womack's answer: "I feel pretty confident about what we have in place," and no one has raised retroactive contract freezes [3].

## The first tests land in January and February

The units should list on the NYSE under SONN within 30 days, the over-allotment window runs into early December, and the new commission's first votes land in January [1][6]. The tell is data-center usage, 59% higher at the last reading, with the next count at fourth-quarter results in early February [3]. [Traders marked the stock down about 1% on pricing day](https://www.tradingview.com/news/seekingalpha:7b1b7670c094b:0-southern-company-plans-1-75b-equity-units-offering-and-notes-repurchases/) [8]. The 8.625% payout is the market's price tag on utility growth capital in this cycle, and Georgia's ratepayers are the ones asked to make it good [8].

## Takeaway

Southern is paying 8.625% and forcing buyers into its stock by 2029 to fund a build that outran its cash flow, just as Georgia's new regulators take office.
