4 terms

Schedule 13G regulatory

"This statement is filed by Highbridge Capital Management, LLC ("Highbridge" or the "Reporting Person")"

A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.

beneficial ownership regulatory

"Amount beneficially owned: The information required by Item 4(a) is set forth in Row 9"

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.

sole dispositive power financial

"Sole Dispositive Power 1,719,358.00"

Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.

shares outstanding financial

"aggregate of 23,000,000 Class A Ordinary Shares outstanding as of March 4, 2026"

Shares outstanding are the total number of a company’s stock units held by all shareholders, including institutional investors and company insiders — think of them as the total number of slices of the company’s ownership pie. Investors use this number to calculate how much of the company each share represents, and it directly affects per-share measures like earnings per share, ownership percentage and valuation; when the slice count changes, an investor’s claim and the company’s per-share metrics change too.
