Series A Cumulative Redeemable Preferred Stock financial

"Title of class of securities: Series A Cumulative Redeemable Preferred Stock"

beneficial ownership financial

"Note to Row 11 Calculated based on the 7,183,812 shares of Preferred Stock outstanding"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

dispositive power financial

"Sole Dispositive Power 456,935.00 8 | Shared Dispositive Power 18,041.00"

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.
