Southern Company reported an insider ownership-change filing for Matthew M. Kim involving Southern Company common stock. The Form 4 was filed on July 2, 2026, and identifies July 1, 2026, as the date of the reported event. The document indicates that Kim had a change in beneficial ownership of Southern Company common stock, but the filing text provided does not include the transaction table that normally specifies the key economic details—such as the number of shares acquired or disposed of, the transaction price, the transaction code, whether the holdings were direct or indirect, or the amount of securities beneficially owned after the transaction. The filing was signed on Kim’s behalf by Brittney Anderson, attorney-in-fact, on July 2, 2026. Because the excerpt does not show the detailed Form 4 line items, it is not possible from this document text alone to determine whether the reported change was an open-market purchase or sale, an option exercise, a restricted stock vesting, a tax withholding, or another insider transaction type. In practical terms, the filing signals that Southern Company disclosed a reportable insider ownership event for Matthew M. Kim in Southern Company common stock as of July 1, 2026. However, without the missing transaction table, investors cannot assess the size, value, pricing, transaction code, or post-transaction ownership from the provided text.
