Restricted Stock Units financial
"the vesting of 25,657 Restricted Stock Units ("RSUs"), which represents 33%"
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.
Performance-based RSUs financial
"These securities consist of the remaining additional performance-based RSUs that were granted"
Performance-based restricted stock units (RSUs) are promises to deliver company shares to employees only if the business meets specific goals, such as revenue, profit, stock-price targets, or strategic milestones. For investors, they matter because they change future share supply and align management incentives with company results—like a salesperson whose bonus only pays out when sales targets are hit—so they can affect earnings, dilution, and confidence in leadership.
2020 Omnibus Incentive Plan financial
"awards were granted pursuant to the terms of RSU agreements under the Sotera Health Company 2020 Omnibus Incentive Plan"
