Restricted Stock Units financial
"Represents the grant of RSUs pursuant to the Plan on May 19, 2026"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
Omnibus Incentive Plan financial
"granted 7,338 restricted stock units ("RSUs") pursuant to the Omnibus Incentive Plan"
An omnibus incentive plan is a single, flexible program a company uses to give employees and executives different types of pay tied to performance — for example stock options, restricted shares, cash bonuses and other awards — all governed by one set of rules. It matters to investors because it determines how many new shares may be created, how leaders are motivated and how much the company will spend on compensation over time; think of it as a master toolbox that affects both costs and the total share supply.
