Key Details

• Transaction date: 2026-06-09; Form 4 filed 2026-06-10 (timely).
• Disposition: 7,235 shares to issuer at $4.39 each = $31,762.
• Derivative activity: entries for conversion/exercise of 24,116 units and an award of 34,169 RSUs (derivative).
• Shares owned after transaction: not specified in the provided extract of the filing.
• Footnotes: RSUs are contingent rights to receive common stock on a one-for-one basis; some RSUs were cash-settled per the board compensation program to address tax obligations. The RSUs were granted June 10, 2025 and fully vested at SIGA’s 2026 annual meeting; up to 10,251 RSUs may be cash-settled at the board’s discretion.

Context

• These entries reflect RSU vesting and partial cash-settlement (often used to cover tax withholding), not an open-market sale. Derivative entries showing $0 typically record conversion/settlement mechanics rather than a market sale. Such issuer dispositions in connection with RSU vesting are routine and do not necessarily signal management’s view of the company’s prospects.
