beneficially owned financial

"The aggregate percentage of shares of Common Stock reported as beneficially owned by the Reporting Person was calculated based on 29,191,000 shares"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

sole voting power financial

"Number of Shares Beneficially Owned by Each Reporting Person With: | 7 | Sole Voting Power 1,795,920.00"

Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.

sole dispositive power financial

"9 | Sole Dispositive Power 1,795,920.00"

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.

Schedule 13D regulatory

"This Amendment No. 16 ( "Amendment No. 16") to initially filed with the Securities and Exchange Commission (the "SEC") on June 22, 2020"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.

Annual Report on Form 10-K regulatory

"based on the Annual Report on Form 10-K filed by the Company on February 26, 2026"

An annual report on Form 10‑K is a required, comprehensive filing that publicly traded companies give to regulators and investors summarizing their business, results of operations, detailed financial statements reviewed by independent auditors, material risks, legal issues and management’s discussion of performance. Investors use it like a company’s year‑end report card and medical checkup: it reveals how the business made money, where it is vulnerable, and the facts needed to compare value, judge risk and make informed investment decisions.
