Sell every share immediately; invest the after-tax cash at the market return for 1 yr, then liquidate. Diversified — no single-stock concentration risk.
Exercise + hold 1 yr
Best payout| Sale proceeds (year 1) | |
| LTCG tax (federal + state + NIIT) | −$4,975 |
| Net at year 1 | $15,688 |
Sold 4,731 shares at exercise to cover strike + tax; 269 shares held 1 yr for LTCG.
Social Security + Medicare are payroll taxes (collectively called FICA) — they apply because you're exercising as a current employee.
Both columns are stated in year-1 dollars: sell-now proceeds compound at the market return and pay LTCG on the gain at year 1; any cash paid out of pocket on the hold side carries the same opportunity cost.

Equity comp at NON INVASIVE MONITORING SYSTEMS INC /FL/
- Gravitics is going public through a reverse merger into the NIMS shell rather than a traditional IPO. Under the merger agreement, each outstanding Gravitics stock option converts into an option to purchase the combined company's common stock under a new 2026 Equity Incentive Plan, with Gravitics stockholders and option holders together ending up owning roughly 95.5 to 96.5 percent of the combined company on a fully diluted basis. The specific vesting, change-in-control acceleration, and early-exercise terms of the new plan were not publicly confirmable this run.
