restricted stock units financial

"Grant of restricted stock units ("RSUs") under the Issuer's 2022 Long-Term Incentive Plan"

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.

RSUs financial

"associated with RSUs previously granted under the Issuer's 2022 LTIP"

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

2022 Long-Term Incentive Plan financial

"under the Issuer's 2022 Long-Term Incentive Plan ("2022 LTIP")"

dividend equivalent rights financial

"in connection with the accrual of dividend equivalent rights associated with RSUs previously granted"

Dividend equivalent rights are promises that mirror the cash payments shareholders get from a company’s profits, but they are paid to holders of certain awards (like stock options or restricted stock units) rather than to actual shares. Think of them as a paycheck top‑up that matches dividends while the award is not yet a real stock, and they matter to investors because they add to employee compensation costs and potential share dilution, affecting company profitability and per‑share value.
