However, Miami International has reported strong financial results recently, including a Q4 2025 earnings and revenue beat, which may help offset any negative sentiment around the executive share sale.

Comly sold the 29,667 shares at an average price of $43.64. Following the sale, she still owns 843,844 shares in Miami International, valued at approximately $36.8 million. The transaction was disclosed in a filing with the SEC.
