- 546 shares sold at $980.000 per share

Costco Wholesale Corp. (COST) – Form 144 filing overview
An affiliate of Costco has filed a Form 144 indicating an intent to sell 546 shares of common stock through Morgan Stanley Smith Barney on or about 18 June 2025. The proposed sale represents an aggregate market value of $535,080, implying a reference price of roughly $980 per share. The shares were originally acquired on 22 October 2024 as restricted stock. Form 144 requires the filer to affirm that no undisclosed material adverse information is known and that any sales will be executed in compliance with Rule 144 volume and manner-of-sale limitations.
The filing notes 443,477,086 shares outstanding, so the disposition equals approximately 0.00012 % of shares outstanding—well below any threshold considered material to Costco’s float or daily trading volume. The filer reports no other sales within the past three months.
Given the small size relative to Costco’s market capitalization and share count, the notice is generally considered routine, low-impact disclosure. It nonetheless signals that a related insider is monetising a minor portion of previously awarded equity.
