beneficial ownership financial
"and therefore, has beneficial ownership. Mr. Bailey disclaims beneficial ownership except to the extent of his pecuniary interests."
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.
stock option financial
"Represents a stock option originally granted by RTB Digital, Inc. on August 12, 2025, which was assumed by the Issuer"
A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.
warrant to purchase common stock financial
"Represents a common stock purchase warrant issued pursuant to the RTB Digital, Inc. Securities Purchase Agreement dated March 6, 2026"
business combination financial
"assumed by the Issuer in connection with the business combination between the Issuer and RTB Digital, Inc."
A business combination happens when two or more companies join together to operate as one, like two friends merging their teams into a single group. This is important because it can change how companies grow, compete, and make money, often making them bigger and more powerful in the market.
pecuniary interests financial
"disclaims beneficial ownership except to the extent of his pecuniary interests."
