ten percent owner regulatory

"each identified as a ten percent owner with respect to Entrada"

weighted average sale price financial

"Price represents the weighted average sale price of the shares sold"

beneficial ownership regulatory

"Each Reporting Person disclaims beneficial ownership of the 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.

pecuniary interest financial

"except to the extent of his or its respective pecuniary interest"

indirect ownership regulatory

"Common stock sale reported as indirect ownership"
