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.

- 546 shares sold at $980.000 per share
- 1 share sold at $978.395 per share

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.
