"James Foster filed a notice of proposed sale of common stock on Form 144"

"Common | 08/10/2026 | Exercise of stock options | Issuer"

aggregate market value financial

"lists an aggregate market value of $7,901,575.00 for the 28,733 shares"

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.
