beneficially owned financial

"These shares may be deemed to be beneficially owned by Jaime Gilinski"

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.

weighted average price per share financial

"in the open market, at a weighted average price per share of $9.58"

aggregate purchase price financial

"acquired 100,000 Common Shares for an aggregate purchase price of $958,204"

The aggregate purchase price is the total amount a buyer pays to acquire a company, assets or securities, including the headline payment plus any assumed debt, fees, taxes and contractually required adjustments. It matters to investors because it shows the true cost of a deal and how much value must be realized after the sale — like knowing the full price of a house once you add closing costs, repairs and outstanding mortgage obligations.

Schedule 13D regulatory

"This Amendment No. 3 amends and supplements the filed on March 12, 2026"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.
