Securities Trading Expert

10% owner Harborne sold 3.2% of his ISSC holdings while maintaining a substantial 1.8M share position worth $23.8M.

Christopher Harborne, a 10% owner of Innovative Solutions & Support Inc (ISSC), has reported a transaction involving the sale of 59,667 shares at $13.2102 per share on June 26, 2025. This transaction had a total value of approximately $788,000. Following this sale, Harborne still maintains beneficial ownership of 1,800,919 shares held indirectly through Klear Kite LLC, a Delaware limited liability company of which he is the sole member.

This sale represents a relatively minor 3.2% reduction in Harborne's overall position in the company. The transaction indicates some portfolio adjustment by a significant shareholder, but the retention of over 1.8 million shares demonstrates continued substantial investment in ISSC. At the reported transaction price, Harborne's remaining stake is valued at approximately $23.8 million.

For context, this transaction provides insight into ownership structure changes at ISSC, though the overall impact appears modest given that Harborne maintains the vast majority of his position. The filing contains no information regarding the rationale behind the sale or whether it relates to company-specific factors versus personal portfolio considerations.
