beneficial ownership financial
"has influence over Heckman Media, LLC's entire holding of 259,933 shares of Common Stock and has beneficial ownership thereof"
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 Options financial
""security_title": "Stock Options" ... "underlying_security_title": "Common Stock, par value $0.001""
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.
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.
exercise price financial
"appropriate adjustments to the number of underlying shares and exercise price"
The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
