beneficially owned financial

"Item 4. | Ownership (a) | Amount beneficially owned: 14,074,945"

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

"(i) Sole power to vote or to direct the vote: 13,141,081"

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

"(iii) Sole power to dispose or to direct the disposition of: 14,074,945"

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 13G regulatory

"all securities reported upon this Schedule. Ariel Fund...subject securities reported upon this Schedule."

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.

economic interest financial

"owns 6,474,663 shares of the Issuer which represents an economic interest in more than 5%"

An economic interest is a right to receive money or other financial benefits from an asset, contract, or business activity without necessarily owning or controlling it; examples include a share of profits, royalties, dividend rights, or scheduled payments. Investors care because it determines who gets cash flow and bears risk — like collecting rent on a house you don’t legally own — and it affects valuation, expected returns, and how exposure to an investment is structured.
