Form 144 regulatory

"Notice of proposed sale of securities disclosed on Form 144."

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.

aggregate market value financial

"Table lists number of shares to be sold and aggregate market value 2058485.85."

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.

Vesting financial

"Nature of acquisition transaction is described as Vesting with issuer as source."

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

Securities Sold During The Past 3 Months financial

"Section titled Securities Sold During The Past 3 Months summarizes recent share sales."
