beneficial ownership financial

"The Reporting Person therefore disclaims beneficial ownership of the stock option and underlying Common Stock."

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.

"subject to the Reporting Person's continuous service through the applicable vesting date."

underlying Common Stock financial
