beneficial ownership financial

"percentage of the beneficial ownership of the Reporting Person"

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 voting and dispositive power technical

"has sole voting and dispositive power over 9,948,173 shares"

unsolicited brokers’ transactions financial

"sold an aggregate of 1,301,827 shares of Common Stock in unsolicited brokers’ transactions"

book-entry form technical

"7,500,000 are held in book-entry form"

A book-entry form is an electronic record showing ownership of securities instead of a paper certificate; think of it like a bank account ledger that notes who owns shares. It matters to investors because it makes buying, selling and transferring securities faster, safer and cheaper by reducing paperwork, loss or forgery risk, and enabling easier settlement through brokers or a central depository.

private placement financial

"closing of the Issuer’s private placement on October 16, 2026"

A private placement is a sale of securities directly to a selected group of investors, typically institutions or accredited investors, instead of through a public offering. It lets a company raise money faster and with fewer regulatory steps; for existing shareholders it matters because the newly issued shares, often sold at a discount, increase the share count and can dilute their ownership.
