Matthew J. Cox, Chairman & CEO, has demonstrated a consistent pattern of selling shares in Matson, Inc. (MATX), as evidenced by SEC Form 4 filings. Over the course of 27 reported transactions, Cox has not engaged in any purchases of MATX shares, with a total sell value exceeding $16.1 million. His recent activity underscores this trend, with four sales executed on July 29, 2026, amounting to approximately $1.95 million. These transactions ranged in value from $70,097.64 to $1.46 million, indicating a mix of smaller and larger disposals. Earlier in 2026, Cox also executed multiple sales in January, including a significant transaction valued at $4.65 million on January 25, 2026, and smaller sales totaling over $1.35 million in the preceding days. This pattern extends back to 2024, with notable sales in January of that year, including a $2.36 million transaction on January 27, 2024. Cox’s trading activity is exclusively tied to MATX, with no diversification into other companies. The absence of any buying activity and the consistent, sizable sales suggest a clear disposition toward reducing his holdings in Matson, Inc. over time.
