[SCHEDULE 13G] Thumzup Media Corporation SEC Filing

Rhea-AI Filing Summary

VirnetX Holding Corp. (VHC) filed a Form 4 reporting an automatic, non-discretionary insider transaction by Chief Scientist Robert D. Short III on 07/07/2025. The company withheld 50 common shares (Transaction Code F) at a price of $12.34 to satisfy payroll and income-tax obligations linked to previously granted restricted stock awards. The explanatory note confirms the transaction is strictly for tax settlement and does not involve an open-market sale.

Post-transaction ownership stands at 31,848 direct shares and 11,278 indirect shares held through The Short Revocable Living Trust, leaving Short’s overall economic exposure essentially unchanged. No derivative securities were exercised, acquired, or disposed of, and no other insider activity was disclosed. Given the immaterial size (≈0.1 % of Short’s total holdings) and its administrative nature, the filing carries limited investment significance and signals no shift in insider sentiment toward VirnetX.

Insights

Securities Analyst

TL;DR: Only 50 shares withheld for taxes; negligible impact and neutral signal.

The Code F designation reveals an automatic share surrender to cover tax obligations on vested stock, a routine event that does not reflect a discretionary buy or sell decision. Post-withholding, the insider still controls roughly 43 k shares, indicating sustained alignment with shareholders. Because the transaction involves less than 1 % of his position and no derivatives, liquidity or valuation impact is essentially nil. From a governance and sentiment perspective, the filing is neutral; it neither strengthens nor weakens the investment case for VHC.
