restricted stock units financial

"These restricted stock units were granted under the issuer's 2022 Omnibus Incentive Compensation 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.

2022 Omnibus Incentive Compensation Plan financial

"granted under the issuer's 2022 Omnibus Incentive Compensation Plan (the "Plan")"

dividend equivalents financial

"Amount includes 84 accrued dividend equivalents acquired during the first and second quarters of 2026"

Payments tied to employee or contractor equity awards that mirror the cash dividends paid on the company’s stock; they give the holder the same economic benefit as owning the shares without transferring actual shares—often paid in cash or additional award units when the award becomes payable. Investors care because these payments affect a company’s compensation costs, cash flow and potential share dilution, and they signal how management is being rewarded and aligned with shareholders.
