restricted stock financial

"Represents a grant of restricted stock under the CME Group Omnibus Stock Plan"

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.

CME Group Omnibus Stock Plan financial

"Represents a grant of restricted stock under the CME Group Omnibus Stock Plan"

vesting financial

"vesting in four equal annual installments, subject to continued service"

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.

continued service financial
