Cloonan Michael, President & CEO of SION, has demonstrated a clear selling bias in recent insider transactions, with no buys recorded in his last 12 trades. Since August 2025, he has executed a series of sales totaling approximately $6.33 million, with the largest single transaction occurring on October 21, 2025, when he sold shares worth $1.07 million. The sales were often accompanied by smaller derivative transactions (coded "M"), likely representing option exercises or related dispositions, which added another $1.22 million in proceeds. Notably, his selling activity intensified in October 2025, with multiple transactions on October 15, 16, and 21, including a $1.25 million sale on the latter date.
Prior to this concentrated selling period, Cloonan had engaged in sporadic but substantial disposals, including a $568,750 sale on August 20, 2025, and a $496,346 transaction on September 26, 2025. His total sell-side activity since August 2025 far outweighs his historical buy-side transactions, which amount to just $1.22 million across all recorded filings. The absence of recent purchases and the sustained liquidation of SION shares suggest a shift in his position, though the reasons remain undisclosed in the filings. The transactions were executed at varying price points, with derivative dispositions consistently representing a smaller fraction of the total value compared to outright stock sales.
