restricted stock units ("RSUs") financial
"Represents restricted stock units ("RSUs"), each of which represents a contingent right"
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.
Stock Option (Right to Buy) financial
"security_title": "Stock Option (Right to Buy)""
market capitalization financial
"result in the Issuer's market capitalization being at or above $4,000,000,000"
Market capitalization is the total market value of a company’s outstanding shares, calculated by multiplying the current share price by the number of shares issued. It gives a quick snapshot of a company’s size and how investors value it, influencing perceived risk, index membership, and roughly how much it might cost to buy the whole company — like using a sticker price to compare the relative size and price of different houses.
consecutive trading days financial
"trades publicly for at least 90 consecutive trading days at or above a price per share"
beneficial ownership financial
"total_shares_following_transaction": "165644.0000""
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.
