beneficially owned regulatory

"The information in Item 4 relating to the shares of the Issuer's common stock ("Common Stock") that are or may be deemed 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.

Schedule 14A regulatory

"as reported by the Issuer in its Definitive Proxy Statement on Schedule 14A filed with the SEC on April 22, 2026"

Schedule 14A is a document that companies file with regulators to share important information with shareholders before a big vote, like approving a merger or election of directors. It matters because it helps investors understand what’s happening so they can make informed decisions about the company’s future.
