[144] Costco Wholesale Corp SEC Filing

Rhea-AI Filing Summary

Southern Company (SO) director David J. Grain filed a Form 4 covering activity on 07/01/2025.

• Deferred compensation grant: Grain received 839.6533 Deferred Stock Units (DSUs) at a reference price of $92.30 per unit under the company’s Deferred Compensation Plan.
• The award is payable only in stock upon termination; it carries no exercise or expiration date.
• After the grant, the director’s total derivative holdings rose to 80,724.3603 DSUs.
• Table I lists a line for 500 common shares marked “D” (disposed), but the form provides no price, code, or contextual detail, limiting insight into that movement.

The filing reflects routine director compensation rather than open-market buying or selling. No material change to share count, governance, or fundamentals is indicated.

Insights

Securities Analyst

TL;DR: Routine DSU grant; negligible impact on SO valuation.

The Form 4 shows David J. Grain, an outside director, accepting ~840 DSUs via Southern’s deferred-compensation program at a reference price of $92.30, lifting his deferred holdings to ~80.7 k units. Because the units convert only at separation and involve no cash outlay or market purchase, the economic impact to current shareholders is de minimis and fully anticipated in the company’s equity-compensation dilution forecasts. The un-elaborated 500-share disposition is too small to affect float or signal sentiment. I classify the disclosure as neutral for investors.
