SIGA Director Julian Nemirovsky Receives RSUs; Surrenders 7,235 Shares

What Happened
Julian Nemirovsky, a director of SIGA Technologies, reported RSU vesting and related derivative activity on June 9, 2026. The filing shows a grant/acquisition of 34,169 RSU-related shares (reported as a derivative award), conversion/exercise activity of 24,116 derivative units, and a disposition to the issuer of 7,235 shares at $4.39 per share for total cash of $31,762. Two derivative entries show conversions/exercises recorded with $0 proceeds, consistent with non‑cash settlement mechanics disclosed in the footnotes.

Key Details

  • Transaction date: 2026-06-09; Form 4 filed 2026-06-10 (timely filing).
  • Reported items:
    • Grant/Award (A): 34,169 RSU-based shares acquired (derivative; $0 reported).
    • Exercise/Conversion (M): 24,116 derivative units reported (one entry as acquired, one entry as disposed at $0).
    • Disposition to issuer (D): 7,235 shares at $4.39 — proceeds $31,762 (cash settlement to issuer).
  • Shares owned after the transactions: not disclosed in the provided excerpt.
  • Footnotes: RSUs are one-for-one contingent rights to common stock; some RSUs are cash-settled to address tax obligations. The RSUs were granted June 10, 2025, fully vested at the 2026 annual meeting; up to 10,251 RSUs may be settled in cash at the Board’s discretion.
  • Transaction codes: A = award/grant, M = exercise/conversion of derivative, D = disposition to issuer.

Context
These entries reflect RSU vesting and related settlement mechanics (including partial cash settlement to cover tax withholding), not an open-market sale. The 7,235-share disposition to the issuer for $31,762 appears to be tax withholding/cash settlement rather than a market sale; such withholding is common when RSUs vest. Derivative exercise/conversion reported with $0 proceeds typically indicates internal conversion/settlement rather than a cash sale to outside investors.
