restricted stock units ("RSUs") financial
"Constitutes an award of restricted stock units ("RSUs") for which the Reporting Person is entitled to receive one (1) share..."
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
pecuniary interest financial
"The Reporting Person disclaims beneficial ownership of such stock, except to the extent of any pecuniary interest therein."
beneficial ownership financial
"The Reporting Person disclaims beneficial ownership of such stock, except to the extent of any pecuniary interest therein."
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.
voting and dispositive power financial
"The Reporting Person is a managing member of PMG XII and PMG SFI and may be deemed to share voting and dispositive power..."
Board of Directors financial
"subject, in all cases, to the Reporting Person's continued service as a member of the Board of Directors through such vesting date."
The Board of Directors is a group of people chosen by a company's owners to help make big decisions and oversee how the company is run. They act like a team of advisors or managers, making sure the company stays on track and meets its goals. Their choices can influence the company's success and how it grows.
