4 terms

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.

2026 Equity Incentive Plan 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."

vesting financial

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

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

continued service financial

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