Class A Common Stock financial

"shares of Boost Run Inc. Class A Common Stock held of record"

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.

Warrants financial

"1,101,986 Warrants being transferred pursuant to the Amended and Restated Transfer Agreement"

Warrants are special documents that give you the right to buy a company's stock at a set price before a certain date. They are often used as a way for companies to attract investors or raise money, and their value can increase if the company's stock price goes up.

Disposition to issuer financial

"transaction_code_description": "Disposition to issuer""

disclaims any beneficial ownership regulatory

"Mr. Goodrich disclaims any beneficial ownership of the securities held by Goodrich ILMJS LLC"

beneficial ownership regulatory

"Goodrich ILMJS LLC is attributed beneficial ownership over the 1,272,885 shares"

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.
