MACROGENICS (MGNX) Sr VP Thomas Spitznagel Receives 175,000 RSUs

What Happened

Thomas Spitznagel, Senior Vice President, Technical Operations at Macrogenics (MGNX), received two RSU grants totaling 175,000 restricted stock units on Feb 12, 2026 (25,000 and 150,000 RSUs). On Feb 15, 2026 he also exercised/converted derivatives resulting in 13,332 shares. To satisfy tax withholding related to the transaction, 5,520 shares were surrendered at $1.71 per share for $9,439.

These were awards and a conversion/exercise of derivatives rather than an open-market purchase or voluntary sale. The RSU grants are reported at $0 (typical for time-based RSU awards); the only cash figure reported is the tax withholding of $9,439.

Key Details

  • Transaction dates: RSU grants on 2026-02-12; derivative exercise/conversion and tax withholding on 2026-02-15. Filing date: 2026-02-17.
  • Grants: 25,000 RSUs and 150,000 RSUs (total 175,000 RSUs) granted @ $0.00 (derivative awards).
  • Exercise/conversion: 13,332 shares reported as exercised/converted (derivative, 2026-02-15).
  • Tax withholding: 5,520 shares disposed to cover tax liability at $1.71/share = $9,439.
  • Shares owned after transaction: Not specified in the filing.
  • Footnotes:
    • F1: On Feb 15, 2023 the reporting person was granted 40,000 RSUs vesting in three equal annual installments; RSUs convert 1-for-1 to common stock.
    • F2: RSUs vest 33% one year after grant and 33% each year thereafter.
    • F3: For the option/derivative grant(s), vesting included 12.5% after one year and 6.25% each quarter thereafter.
  • Timeliness: Filing covers 2/12 and 2/15 transactions and was filed 2/17/2026. (Note: Form 4 is typically due within two business days of a transaction; the 2/12 grant was reported after that window while the 2/15 items were filed within the typical two-day window.)

Context

  • RSUs are time-based awards that convert into shares when they vest; they are not an immediate cash purchase and do not by themselves signal a market buy or sell.
  • The 5,520-share disposition is a tax withholding/payment action (common when RSUs or exercised derivatives vest/are converted), not necessarily a voluntary sale for investment reasons.
  • This filing is informational; it reports awards and a derivative conversion rather than an open-market purchase or a large voluntary sale.
