restricted stock unit financial

"Includes 32,585 restricted stock unit awards."

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

dividend equivalents financial

"additional restricted stock units accrued as dividend equivalents based on the Issuer's quarterly dividend"

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.
