restricted stock financial

"issuance of restricted stock with a value of $42,500"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

non-employee director compensation program financial

"The non-employee director compensation program"

average closing price financial

"based on the average closing price during June 2026"

The average closing price is the arithmetic mean of a security’s end-of-day prices over a chosen period, found by adding each day’s closing price and dividing by the number of days. It smooths out daily ups and downs to show a typical market value—like averaging daily temperatures to understand a month’s climate—and helps investors spot trends, judge whether a stock is generally rising or falling, and make clearer buy or sell decisions.
