beneficially owned financial

"Aggregate amount beneficially owned by each reporting person 130,610,615.87"

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.

Schedule 13D regulatory

"This /A constitutes Amendment No. 10 to the on behalf of the John and Daria Barry Foundation ... and Amendment No. 12 to the of John F. Barry III"

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.

dividend reinvestment plan financial

"78,396.77 Shares purchased with dividends through the Issuers dividend reinvestment plan"

A dividend reinvestment plan lets shareholders automatically use cash dividends to buy more shares of the same company instead of receiving the money. It matters to investors because it turns regular payouts into a steady way to grow ownership and take advantage of compound returns—like having your savings automatically buy additional slices of a pie over time—while often reducing transaction costs and smoothing purchase timing.

weighted average price per share financial

"Amount of Securities Weighted Average Price per Share Type 5/21/2026 John F. Barry III 100,000.00 $2.2766 Purchase"

sole voting power financial

"Number of Shares Beneficially Owned by Each Reporting Person With: | 7 | Sole Voting Power 130,184,416.49"

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 130,184,416.49"

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.
