Key Terms

Schedule 13G/A, beneficially owned, voting power, dispositive power

4 terms

Schedule 13G/A regulatory

"form_type: "SCHEDULE 13G/A""

A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.

beneficially owned financial

"the Reporting Person beneficially owned 419,000 shares of Common Stock"

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.

voting power financial

"Sole Voting Power 239,000.00 6 | Shared Voting Power 180,000.00"

Voting power is the ability shareholders have to influence a company's major decisions—like electing the board, approving mergers, or changing corporate rules—based on the voting rights attached to the shares they hold. For investors it matters because greater voting power is like holding more keys to a building: it gives you a stronger say over management choices and the company’s strategy, which can affect future value and risk.

dispositive power financial

"Sole Dispositive Power 239,000.00 8 | Shared Dispositive Power 180,000.00"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
