Teresa A. Jones, Executive Vice President and Director of Costco Wholesale Corp (COST), reported a sale of company shares on 08/20/2025. The Form 4 shows she disposed of 600 shares of Common Stock at a price of $992.05 per share, leaving her with 2,362.125 shares beneficially owned after the transaction. The filing notes that 1.183 shares were inadvertently omitted from prior reports and are included in the post-transaction total. The form was executed on behalf of the reporting person by an attorney-in-fact, Alejandro Torres, on 08/22/2025. The filing is a single-person Form 4 disclosure and contains only this non-derivative sale.
Costco proposed insider sale notice: The filing reports a proposed sale of 600 common shares via Fidelity Brokerage Services with an aggregate market value of $595,230.06. The shares represent a small fraction of the reported 443,477,086 shares outstanding. The approximate sale date is 08/20/2025 on NASDAQ. Acquisition history shows 25 shares received as compensation on 01/15/2014 and 575 shares from restricted stock vesting on 10/22/2023. The filer certifies they are not aware of undisclosed material adverse information.
Costco Wholesale Corp. (COST) – Form 144 filing: An unidentified insider has filed notice of intent to dispose of 4,000 common shares through Fidelity Brokerage Services on or about 14 Jul 2025. The proposed sale is valued at $3.90 million (≈ $975 per share) based on the aggregate market value disclosed.
The shares stem from two tranches of restricted-stock vesting received from the issuer: 1,562 shares vested on 22 Oct 2022 and 2,438 shares vested on 15 Sep 2023. No sales have been reported by this insider in the past three months, and the filer affirms no knowledge of undisclosed adverse information.
Relative to Costco’s 443.48 million shares outstanding, the disposition represents roughly 0.001 % of total equity—an immaterial dilution risk. While insider selling can raise sentiment concerns, the modest size suggests portfolio diversification rather than a signal of operational weakness.
Costco Wholesale Corp. (COST) – Form 4 Insider Transaction
Director Susan L. Decker reported two open-market sales of Costco common stock on 18 June 2025:
- 546 shares sold at $980.000 per share
- 1 share sold at $978.395 per share
Following the sales, Decker’s direct beneficial ownership declined from 11,531.936 to 11,530.936 shares, a reduction of roughly 0.005% of her holdings. No derivative transactions were reported and no Rule 10b5-1 trading plan box was checked.
The transaction size is small relative to both Decker’s remaining position and Costco’s 443 million shares outstanding, implying no material impact on the company’s capital structure or insider sentiment indicators.
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.
