Rule 10b5-1 trading plan regulatory
"The sale was effected pursuant to a 10b5-1 trading plan dated May 7th, 2025."
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
restricted stock units financial
"Includes 10,957 shares issuable on the settlement of restricted stock units granted."
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
weighted-average price financial
"The price reported in column 4 is a weighted-average price."
Weighted-average price is the average of multiple prices where each price is counted according to its size or importance—larger trades carry more weight than smaller ones, like averaging course grades by credit hours. It matters to investors because it gives a more realistic picture of the true price paid or received, helping assess trade execution, compare performance, calculate cost basis, and value positions more accurately than a simple average.
Stock Option (Right to Buy) financial
"Derivative security titled Stock Option (Right to Buy) for 20,000 shares."
