Rule 10b5-1 trading plan regulatory
"Sale of shares effected pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person..."
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.
weighted average price financial
"The price reported above is a weighted average price. The shares were sold in multiple transactions..."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
Stock Option (Right to Buy) financial
"Stock Option (Right to Buy) ... conversion or exercise price $3.5700 ... underlying Common Stock"
vesting financial
"one quarter of which will vest on January 25, 2024, with the remaining three quarters vesting in equal monthly installments..."
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.
estimated tax withholding financial
