Key Terms

stock options, vest, incentive compensation plan

3 terms

stock options financial

"Stock options (right to buy)"

Stock options are agreements that give a person the right to buy or sell a company's stock at a specific price within a certain time frame. They are often used as a reward or incentive, similar to a coupon that can be used later if the stock price rises, allowing the holder to make a profit.

vest financial

"These options vest in 12 equal installments"

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

incentive compensation plan financial

"amended and restated 2023 incentive compensation plan"

An incentive compensation plan is a formal program that rewards employees and executives with bonuses, stock, or other payments tied to specific performance goals—such as revenue, profit, productivity, or long‑term share price. Investors watch these plans because they shape how leaders make decisions and take risks; like paying a coach by wins rather than effort, well‑designed plans can drive sustainable growth while poor designs can encourage short‑term behaviors that harm shareholder value.
