Stock Option Definition

A stock option is a contract that gives the holder the right — but not the obligation — to buy or sell a specific number of shares at a predetermined price (the strike price) within a set time period. In a business context, stock options are most commonly used as employee compensation to attract and retain talent.

Stock Option in Practice — Example

Your startup offers a key hire 10,000 stock options with a strike price of $2 per share, vesting over four years. After year one, 2,500 options vest. If the company's shares are worth $10 by then, the employee can exercise those options — buying shares at $2 each and immediately owning something worth $10 each. That's a $20,000 paper gain on just the first batch. The remaining options vest monthly over the next three years.

Why Stock Option Matters for Your Business

Stock options are one of the most powerful tools for attracting top talent, especially when your business can't compete on salary alone. They align employee interests with company growth — when the company succeeds, option holders benefit directly.

For startups and growing businesses, options let you compensate team members with future value instead of current cash. This preserves cash flow while giving employees real upside. It's why stock options are standard in tech, but they're increasingly used in other industries too.

However, stock options also create complexity. You need a formal equity incentive plan, 409A valuations, vesting schedules, and clear documentation. The tax implications for both the company and employees can be significant. Getting professional guidance upfront prevents expensive mistakes.

How Stock Options Work

TermMeaning
Grant dateWhen options are awarded
Strike pricePrice at which shares can be purchased
Vesting scheduleTimeline for earning the right to exercise
CliffMinimum time before any options vest (usually 1 year)
ExerciseBuying shares at the strike price
ExpirationDeadline to exercise (typically 10 years from grant)

Common vesting schedule: 4-year vesting with a 1-year cliff. After the cliff, 25% vest immediately, then the rest vest monthly or quarterly over 3 years.

Types:

  • ISOs (Incentive Stock Options): Tax-advantaged, employees only, $100K annual limit
  • NSOs (Non-Qualified Stock Options): No tax advantages, available to anyone
  • Stock Option vs Restricted Stock

    Stock options give you the right to buy shares at a set price — they're worthless if the share price never exceeds the strike price. Restricted stock grants you actual shares upfront, subject to vesting. Restricted stock always has some value (unless the company goes to zero), while options can expire worthless.

    FAQ

    Q: Do stock options cost the employee anything?

    A: Yes — to exercise options, the employee pays the strike price multiplied by the number of shares. If the strike price is $2 and they exercise 1,000 options, they pay $2,000. There may also be tax implications at exercise.

    Q: What happens to stock options if an employee leaves?

    A: Typically, unvested options are forfeited. Vested options usually must be exercised within 90 days of departure, though some companies offer extended exercise windows.
