beneficially owned financial

"aggregate number of shares of Common Stock and percentage of Common Stock beneficially owned"

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: Sole Voting Power"

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

"Number of Shares Beneficially Owned by Each Reporting Person With: Sole Dispositive Power"

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.

open-market transactions financial

"Cascade purchased 3,762,705 shares of Common Stock in open-market transactions"

Open-market transactions are purchases or sales of a company’s securities that take place on public exchanges rather than through private agreements. They matter to investors because these trades change the number of shares available, can move the stock price, and often signal management’s view of the company’s value—like a store restocking or clearing shelves, altering supply and the price shoppers see.

weighted-average price per share financial
