Claudine Adamo, Executive Vice President at Costco Wholesale Corporation (COST), has demonstrated a consistent pattern of selling activity over the past two years, with no recorded purchases in SEC filings. Since early 2024, Adamo has executed 24 transactions exclusively involving COST shares, all of which were sales or dispositions, totaling approximately $11.8 million in aggregate value. The largest single sale occurred on September 30, 2024, when Adamo disposed of shares worth $2.84 million, followed by another significant sale of $2.53 million on October 24, 2025. More recently, on March 9, 2026, she sold $732,205 worth of stock, reinforcing the ongoing divestment trend.
Adamo’s transactions frequently involve multiple filings on the same date, particularly in October of both 2024 and 2025, where she executed several smaller dispositions ranging from $86,974 to $187,698 per filing. These appear to be systematic sales, possibly tied to scheduled trading plans. The absence of any buy transactions suggests a one-directional approach to equity management, with Adamo steadily reducing her COST holdings over time. While the sales could reflect personal financial planning, the consistency and scale of the disposals—particularly the multi-million-dollar transactions—highlight a clear bias toward liquidity over retention.
