"Mr. Bradley disclaims beneficial ownership of such securities except to the extent of his pecuniary interest"

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.

FAQ

What insider transactions did Datavault AI (DVLT) report for CEO Nathaniel Bradley?

Why was this Datavault AI (DVLT) Form 4/A filed as an amendment?
