Restricted Stock Units financial
"Each restricted stock unit represents a contingent right to receive one share"
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.
pecuniary interest financial
"disclaims any beneficial ownership... other than his pecuniary interest therein"
beneficial ownership financial
"The Reporting Person disclaims any beneficial ownership of any shares of 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.
voting power and dispositive power financial
"may be deemed to have voting power and dispositive power over the shares"
stock options financial
"All shares of common stock subject to stock options held by the Reporting Person are vested"
Stock options are agreements that give a person the right to buy or sell a company's stock at a specific price within a certain time frame. They are often used as a reward or incentive, similar to a coupon that can be used later if the stock price rises, allowing the holder to make a profit.
