What stands out

Four officers sold shares but ended with larger stakes, because more shares came in than were sold: Stan Connally (sold 12K, 7.6% of starting holdings; 49K added), Christopher Cummiskey (sold 6.7K, 24% of starting holdings; 27K added) and Peter Sena III (sold 4.3K, 28% of starting holdings; 29K added), plus 1 more.Stan Connally: largest sale, Mar 18, 2026 · Christopher Cummiskey: largest sale, Mar 19, 2026 · Peter Sena III: largest sale, Sep 3, 2026

Kimberly Greene sold 27% of vested holdings: 25K shares for $2.4M, all under a disclosed plan.Largest sale, Mar 30, 2026

Tax withholding outweighed market sales: the company withheld $25.2M of officers' and directors' shares for taxes, against $5.6M sold on the open market. The largest was Christopher Womack ($8.9M withheld).Largest withholding, Feb 16, 2026

Percentages cover 18 of 26 officers and directors. 8 are left out

Left out: Anthony Earley Jr. and Matthew Kim (holdings couldn't be fully reconciled); Donald James, Dale Klein, Janaki Akella, Kristine Svinicki, David Meador and James Etheredge (held no vested shares at the start).

Disclosed company stock is not an insider's whole wealth.

Who sold, and how much of their stake

Officers and directors, past 12 months. Each bar is 100% of that person's own stake; not comparable between people. The stake is the vested shares held at the start of the period (Oct 9, 2025); the gold part is what they sold.

Common questions

Is the Southern Company CEO selling stock?

No. James Kerr II reported no open-market sales in the past 12 months.

Why are Southern Company insiders selling?

Filings rarely give a reason, and we don't guess at one. What they show is how the sales were made: 86% of sales by value ran under 10b5-1 trading plans disclosed in the filings and 14% had no disclosed plan. A trading plan schedules sales in advance.

Are any Southern Company insiders buying?

No. Officers and directors reported no purchases in the past 12 months.

How much of their stake did Southern Company insiders sell?

About 6.3% overall. As a group they ended with more shares than they started with. The biggest individual seller, Kimberly Greene, sold shares equal to 27% of starting holdings, but more vested, so the stake grew. That covers the 12 months to Oct 9, 2026 and counts vested shares reported on SEC Forms 3, 4 and 5, which is not an insider's whole wealth.

24 of 26 insiders fully reconciled: starting holdings plus reported transactions match ending holdings (15 exactly, 9 with a minor or footnoted difference). For 2 we show sales but not holdings; the ! icon on their rows explains why. Percentages cover 18 of 26 officers and directors. Left out: Anthony Earley Jr. and Matthew Kim (holdings couldn't be fully reconciled); Donald James, Dale Klein, Janaki Akella, Kristine Svinicki, David Meador and James Etheredge (held no vested shares at the start). "Still held" compares ending with starting vested shares; a plus sign means the holding grew.

What explains the selling$5.6M of sales by plan status, purpose, seller and month

Officer and director open-market sales: $5.6M across 58,891 shares. Plan status and stated purpose are separate questions, and a sale can have both.

By plan status

Disclosed plan · $4.9M · 86%

14%

The lighter segment is sales with no plan disclosed in the filing ($768K), including tax-related sales outside a plan.

No plan disclosed · $768K

Sales with no 10b5-1 plan and no tax reference in the filing. $644K of it is Christopher Cummiskey. No plan disclosed is a statement about the filing, not about why the sale happened. Largest such sale: Christopher Cummiskey, Mar 19, 2026

Taxes

277,534 shares ($25.2M) were withheld by the company for taxes, which isn't a market sale.

Charitable gifts · 36K shares

Gifts the filings describe as charitable. Gifts are not sales and are not included in the sale totals.

Open-market sales (Form 4 code S) by people who were officers or directors, in split-adjusted shares. Earlier years include people who have since left. A sale that an outside holder also reports (a family trust, a fund) is counted with outside holders in every year. Shares, not dollars, are compared, so a change in the stock price doesn't look like a change in selling. Years the filings don't fully cover are shown but left out of the average.

Sources and methodology3,571 filings from SEC EDGAR, and how we read them

All 3,571 Forms 3, 4 and 5 filed for Southern Company (SEC CIK 92122) from May 9, 2003 to Oct 5, 2026, retrieved from SEC EDGAR on Oct 9, 2026. Prices are the ones reported in each filing, often weighted averages.

Holdings. Each holding line (a share class plus an owner, such as a trust or LLC) carries its last reported balance forward. Entities first reported during the period start at zero, so transfers between an insider's own trusts don't count as selling. Lines not reported for three years or more are listed separately and left out of totals.

Sales. A sale counts as under a 10b5-1 plan if its footnote cites one or the filing's Rule 10b5-1 box is checked, and as tax-related if its footnote cites tax obligations or sell-to-cover. Shares withheld by the company for taxes are listed separately. Sales with neither attribute are labeled "no plan disclosed".
