Signing Day (SGN) President Jeffry Hecklinski Surrenders Shares in Merger
What Happened Jeffry Hecklinski, President and Director of Signing Day Sports, reported dispositions to the issuer on March 16, 2026 related to the closing of a business combination. He surrendered 9,262 Signing Day common shares and 834 derivative interests (listed as dispositions to the issuer). Under the merger terms, each Signing Day share converted into 0.09334 common shares of BlockchAIn; that conversion yielded roughly 942 BlockchAIn shares in total, valued at about $4,300 using BlockchAIn’s first reported NYSE American sale price of $4.60 on March 17, 2026. The 834 derivative interests were related to an option that was assumed and converted in the transaction.

Context
- “Disposition to the issuer” here reflects a corporate reorganization (shares exchanged/surrendered in the business combination), not an open-market sale — so it’s a corporate-driven conversion rather than a personal liquidity event executed on the market.
- The derivative line reflects an option that vested and was assumed/converted by the surviving company; it was not reported as an exercised-for-cash transaction.
- This filing is informational about the conversion from Signing Day to BlockchAIn stock and does not by itself indicate insider sentiment about the new company.
