Equity comp at SentinelOne
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

If a meaningful share of your net worth sits in S, concentration risk is the question. This calculator quantifies drawdown impact at 30 / 50 / 70%, and the trade-off between selling down (tax cost now) versus hedging (option premium drag), auto-filled with S's option-implied volatility.
Example: 5,000 S shares at $15.03 is a $75,150 position. A 30% drawdown costs $22,545; a 50% drawdown costs $37,575; a 70% drawdown costs $52,605. The calculator quantifies the trade-off between selling down (immediate capital-gains tax) and hedging (option premium drag) using S's option-implied volatility and your cost basis.

SentinelOne equity questions
- How much S stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your S position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does SentinelOne grant ISOs, NSOs, or RSUs?
- Equity compensation at SentinelOne typically takes the form of incentive stock options (ISOs), non-qualified stock options (NSOs), and restricted stock units (RSUs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise. Restricted stock units are taxed as ordinary income when they vest.
- Do SentinelOne RSUs use double-trigger vesting?
- No. SentinelOne restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
