Insights

Financial Analyst

TL;DR: Small insider distribution of 211 shares by a trustee; immaterial to Costco’s capital structure.

The filing documents a distribution from the Stanton Family Trust to a beneficiary on 09/02/2025 that reduced the trust’s indirect holdings by 211 shares. As reported, the reporting person disclaims beneficial ownership of the shares now held by his son. This is a routine trust distribution and does not indicate a sale or broader change in holdings disclosed in this form. There are no sales reported, no derivative activity, and no change to aggregate public float disclosed here.

Corporate Governance Expert

TL;DR: Trustee-led transfer documented correctly; disclosure aligns with Section 16 reporting requirements.

The Form 4 lists the reporting person as a director and trustee and provides the required disclosure that the trust distributed 211 shares to a beneficiary (the reporting person’s son) on 09/02/2025. The reporting person explicitly disclaims beneficial ownership of both the distributed shares and those remaining in the trust, which is a common governance disclosure when trustees transfer trust assets to beneficiaries. The form is properly executed by an attorney-in-fact and contains no indication of a 10b5-1 plan or derivative transactions.
