Stock Options, RSUs, and ESPPs: A Complete Guide to Equity Compensation in 2026

Equity compensation has become a standard part of total compensation packages, especially in technology, biotech, and finance. But many employees don't fully understand what they're receiving. This guide breaks it all down.

Types of Equity Compensation

Stock Options

You receive the right to purchase company stock at a predetermined price (the "strike price"). If the stock price rises above the strike price, you profit from the difference.

Best for: Early-stage companies with high growth potential Risk level: High — worthless if the stock price stays below the strike price

Restricted Stock Units (RSUs)

You receive actual shares of stock that vest over time (typically 4 years with a 1-year cliff). Unlike options, RSUs always have value as long as the stock has value.

Best for: Established public companies Risk level: Medium — value fluctuates with stock price but never goes to zero

Employee Stock Purchase Plans (ESPPs)

You can purchase company stock at a discount (typically 10-15%) through payroll deductions. Often includes a "lookback" provision that uses the lower of two prices.

Best for: Any public company employee — essentially free money Risk level: Low — the discount provides a built-in buffer
