restricted stock units (RSUs) financial
"The reported transaction involved the reporting person's receipt of a grant of 3,457 restricted stock units (RSUs) under the Merit Medical Systems, Inc. 2026 Equity Incentive Plan."
Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.
Non-qualified stock options financial
"Non-qualified stock options (right to buy)"
Non-qualified stock options are a type of employee benefit that gives individuals the right to buy company shares at a set price, usually lower than the market value, within a certain period. Unlike other options that may have special tax advantages, these options are taxed as income when exercised, which can affect how much money the employee or investor ultimately gains. They are important because they can influence company compensation strategies and impact the financial outcomes for employees and investors.
Equity Incentive Plan financial
"under the Merit Medical Systems, Inc. 2026 Equity Incentive Plan."
An equity incentive plan is a program that gives employees, executives or directors the right to receive company stock or options to buy stock as part of their pay. Think of it as offering slices of future company profit to motivate people to boost long‑term performance; for investors it matters because it can align employee goals with shareholder value but also increases the number of shares outstanding, which can dilute existing ownership.
exercise price financial
"exercisePrice": "52.1700""
The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
expiration date financial
"expirationDate": "2026-05-31T00:00:00.000Z""
The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised. It matters to investors because it determines the timeframe during which they can take action or benefit from the contract, similar to how a coupon or a food item has a limited period of usefulness. Once the expiration date passes, the contract loses its value or ability to be used.
