Cummiskey Christopher 4

What Happened

• Christopher Cummiskey, EVP of Southern Co (SO), received shares upon vesting of performance/share and restricted stock units on Feb 11, 2026. He was credited 22,178 shares from the 2023–2025 performance share award and 1,490 shares from the first 1/3 vesting of the Feb 5, 2025 restricted stock unit award.
• To satisfy required tax withholding, a total of 10,618 shares were withheld (9,880 shares and 738 shares) valued at $90.86 per share, resulting in withholding amounts of $897,697 and $67,055 (total $964,752). The filings also show conversion/exercise entries (M) tied to the vesting/settlement of those awards.

Key Details

• Transaction date: Feb 11, 2026; Form 4 filed Feb 13, 2026 (appears timely).
• Grant/settlement: 22,178 shares (performance share units, 2023–2025) and 1,490 shares (first 1/3 of 2025 restricted stock units). Includes accrued dividend equivalent units (footnotes F1, F3).
• Withholding/tax payments: 9,880 shares and 738 shares were withheld at $90.86 to satisfy federal/state tax withholding (footnote F2).
• Additional derivative entry: a 1,441-share M-line appears in the filing associated with conversion/disposition of derivative units (see footnote F4 for RSU vesting schedule and settlement mechanics).
• Shares owned after the transaction: not specified in the provided filing excerpt.
• Footnotes: Committee certified performance on Feb 11, 2026; remaining RSU tranches vest in 2027 and 2028 (F1–F4).

Context

• These actions are routine award settlements: performance share units and restricted stock units vested and were converted to common stock. The “disposals” reported are shares withheld to cover tax liabilities (a cashless/withholding settlement), not open-market sales signaling a directional bet.
• Transaction codes: A = award/acquisition on vesting, M = exercise/conversion of derivative awards, F = shares withheld to satisfy tax obligations.
