Insights

Equity Compensation Analyst

Routine annual option grant to an Arcturus director, not a market trade.

The filing shows Jing L. Marantz, a director of Arcturus Therapeutics Holdings Inc., receiving stock options for 15,000 shares at an exercise price of $7.30 per share, expiring on June 5, 2036. This is coded as a grant/award acquisition.

The footnote explains this is the 2026 annual grant for Board service, with monthly vesting over one year. Such awards are standard equity compensation rather than open-market buying or selling, so the informational signal for investors is limited and best viewed as a routine governance and incentive practice.
