4 terms

restricted stock units financial

"in connection with the vesting of restricted stock units ("RSUs")"

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.

sell to cover financial

"pursuant to a "sell to cover" provision included in the RSU Agreement"

Sell to cover is when a person who receives company stock through options or awards sells just enough shares immediately to pay required taxes, exercise costs, or fees, keeping the rest. Think of it like cashing part of a bonus to cover the tax bill so you can keep the remainder. For investors, it can create predictable small selling pressure and slightly change the number of shares actually held by insiders without increasing long‑term dilution.

weighted average sales price financial

"Represents the weighted average sales price per share."

tax withholding obligations financial

"effected to cover tax withholding obligations in connection with the vesting"
