3 terms

Rule 10b5-1 trading plan regulatory

"The sales were effected pursuant to the Reporting Person's 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 price reported above reflects the weighted average sale price."

vesting financial

"A portion of these shares is subject to vesting."

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.
