An Employee Stock Purchase Plan (ESPP) is a program that allows employees to buy shares of their company's stock at a discounted price. Typically, employees can contribute a portion of their salary to purchase stock during specific offering periods. This plan encourages employees to invest in the company and can lead to financial benefits if the stock price increases. ESPPs often have specific rules regarding eligibility, contribution limits, and purchase periods. Employees may also enjoy tax advantages depending on the plan's structure. Overall, an ESPP can be a valuable way for employees to build wealth while supporting their company's growth.
