Aggregate market value financial

"Aggregate market value of 8611874.57"

Aggregate market value is the combined price you would pay to buy all outstanding shares of a company or all companies in a group at current market prices — essentially the sum of each stock’s market capitalization. It matters to investors because it shows the overall size and weight of an investment or sector (like the total cost to buy every piece of a puzzle), helps compare scale across companies or markets, and influences index composition and risk exposure.

Registered plan financial

"Exercise of Options Under a Registered Plan"

A registered plan is a savings or investment account that a government recognizes for special tax treatment and rules, such as limits on how much you can put in and conditions for withdrawals. For investors it matters because those rules change how much of your gains are taxed, how quickly your money can be accessed and what strategies make sense — like a labeled jar that gives tax breaks but comes with rules about when and how you can take the money out.

Gross proceeds financial

"Gross Proceeds 1539992.02"

The total amount of cash a company receives from a financing event or sale before any fees, expenses, taxes or deductions are taken out. Investors watch gross proceeds because it shows the raw scale of new capital being raised—think of it as the paycheck amount before withholdings—which helps assess how much funding is available for operations, growth, debt payoff or how much shareholder dilution might occur once costs are removed.
