"As of the close of business on the date hereof, Mr. Brumder may be deemed to beneficially own 14,703,132"

Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

Proxy Statement on Schedule 14A regulatory

"as reported in the Proxy Statement on Schedule 14A, filed by the Issuer on April 17, 2026"

A proxy statement on Schedule 14A is the official, regulator-filed packet of information companies send to shareholders before a vote, like a mailed agenda and background materials for a town-hall meeting. It explains who is running for the board, items up for approval, key executive pay and risks, and how to vote — details investors use to judge leadership, governance and potential changes that can affect share value.
