restricted stock units (RSUs) financial

"The reported transaction involved the reporting person's receipt of a grant of 3,457 restricted stock units (RSUs)"

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.

2026 Equity Incentive Plan financial

"under the Merit Medical Systems, Inc. 2026 Equity Incentive Plan"

vest financial

"The RSUs granted to the reporting person will vest on May 3, 2027."

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.

continued service financial

"Vesting of the RSUs is subject to continued service to the issuer through the vesting date."
