restricted stock units financial

"Reflects the partial disposal of restricted stock units granted to the reporting person on March 28, 2024"

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.

withholding taxes financial

"to satisfy withholding taxes applicable upon vesting of the March 28, 2024 and March 28, 2025 grants"

Withholding taxes are amounts a payer or government takes out of payments — such as wages, interest, or dividends — before the recipient gets the money, functioning like a cashier keeping part of a bill to pay taxes on your behalf. For investors this matters because it reduces the cash they actually receive, affects net returns and yield calculations, and may require additional paperwork or treaty claims to recover or offset the withheld amount against final tax bills.

2022 Long Term Incentive Plan financial

"under the 2022 Long Term Incentive Plan. This disposal covers withholding taxes"

pecuniary interest financial

"disclaims beneficial ownership of these securities except to the extent of his pecuniary interest therein"

beneficial ownership financial

"The reporting person disclaims beneficial ownership of these securities except to the extent"

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.
