4 terms

Rule 10b5-1 trading plan financial

"The sales were effected pursuant to a Rule 10b5-1 trading plan"

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 sale price financial

"The weighted average sale price for the transaction report was $21.95"

Employee Stock Option (right to buy) financial

"Security title listed as Employee Stock Option (right to buy)"

vesting financial

"25% of the shares subject to the option vested on October 16, 2024"

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.
