Key Terms

Form 144, business combination, aggregate market value

3 terms

Form 144 regulatory

"144: Securities Information Common Stock"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

business combination financial

"Acquired in connection with a business combination which closed on January 24, 2023."

A business combination happens when two or more companies join together to operate as one, like two friends merging their teams into a single group. This is important because it can change how companies grow, compete, and make money, often making them bigger and more powerful in the market.

aggregate market value financial

"9338 | 11672.50 | 58826140 | 08/17/2026"

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.
