restricted stock units financial

"These securities consist of 14,970 restricted stock units ("RSUs") that were granted on May 22, 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.

2020 Omnibus Incentive Plan financial

"pursuant to the terms of an RSU agreement under the Sotera Health Company 2020 Omnibus Incenctive Plan"

vesting conditions financial

"Each RSU represents the Reporting Person's right to receive one share of Common Stock, subject to vesting conditions"

Vesting conditions are the rules that determine when someone earning company stock or stock options actually gains the right to keep or sell them, typically based on staying with the company for a set time or meeting performance targets. Think of it like keys that unlock gradually — some unlock by calendar date, others only after agreed milestones. Investors care because vesting shapes management incentives, the timing of share sales, and the number of shares that can enter the market, which can affect a company's valuation and ownership mix.

non-employee director financial

"subject to the Reporting Person's continued service as a non-employee director of the Issuer through such date"
