restricted stock award financial
"Represents a restricted stock award originally granted by RTB Digital, Inc. on October 10, 2025, which was assumed by the Issuer in connection with the business combination"
A restricted stock award is company shares given to an employee or executive that cannot be sold or fully owned until certain conditions—like staying with the company for a set time or hitting performance targets—are met. Think of it as a gift that only becomes yours after you fulfill specific obligations; for investors, these awards matter because they can increase the total shares outstanding when they vest, reveal how management is being paid and motivated, and create potential selling pressure when restrictions lift.
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.
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.
vesting schedule financial
"continues to vest in accordance with its original vesting schedule, subject to the Reporting Person's continued service"
A vesting schedule is a timeline that determines when someone gains full ownership of certain benefits, such as company stock or retirement contributions. Think of it like earning the right to own a gift gradually over time, rather than receiving it all at once. It matters to investors because it affects when they can fully access or sell these benefits, influencing their financial planning and decision-making.
exercise price financial
"appropriate adjustments to the number of underlying shares and exercise price, and continues to vest"
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.
