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.

tax withholding obligations financial

"sold by the Reporting Person to cover tax withholding obligations in connection"

beneficial ownership financial

"may be deemed to share beneficial ownership of these securities."

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

co-trustee financial

"The Reporting Person is a co-trustee of the ACP 2021 Trust"
