Insights

Equity compensation analyst

Routine time-based option grant to CFO; non-cash, standard terms.

Simulations Plus granted the EVP/CFO 32,500 stock options at an exercise price of $16.02 on 10/16/2025. The options expire on 10/15/2035 and vest in four equal annual tranches.

This is a typical executive compensation structure using time-based vesting. It aligns continued service with potential value realization, with actual outcomes depending on future share price and continued employment.

The filing lists direct ownership of the derivative securities after the grant. No cash changes hands at grant; any future value depends on option exercise and market price at that time.
