indirect ownership financial

"The filing shows 2,065,385 shares of Class A Common Stock held indirectly as of May 8, 2026"

Warrants financial

"along with 1,101,986 warrants exercisable into Class A shares at an exercise price"

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.

beneficial ownership financial

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

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.

pecuniary interest financial

"other than to the extent of any pecuniary interest he may have therein"

Amended and Restated Transfer Agreement financial

"which may be transferred pursuant to the Amended and Restated Transfer Agreement, dated as of April 24, 2026"
