The details were disclosed in a recent filing with the Securities and Exchange Commission (SEC) on October 27, 2026. This filing is significant as it reflects the ongoing management activities and stock ownership adjustments by a key executive in one of the largest retail companies in the world.

The filing outlines several transactions that occurred on October 22, 2026. Christopher acquired a total of 4,552 shares of Costco common stock, which brought his total ownership to 52,223 shares. Additionally, he disposed of several blocks of shares, totaling 3,730.13 shares, at a price of $1,018.21 per share.
