Explanation of Responses:

( 1 )The Company withheld shares of common stock to satisfy the tax withholding obligation for the Reporting Person's Restricted Stock Units that vested on February 24, 2023. ( 2 )Includes Restricted Stock Units that have not yet vested. ( 3 )In connection with the vesting on February 24, 2023 of Restricted Stock Units previously granted to the Reporting Person, the Reporting Person's receipt of 636 shares of The Brink's Company ("BCO") common stock was deferred, resulting in 636 Program Units (each of which is the economic equivalent of one share of BCO common stock) credited to the Reporting Person's stock incentive account under the terms of the Key Employees' Deferred Compensation Program. The Reporting Person is therefore reporting the disposition of 636 shares of BCO common stock in exchange for an equal number of Program Units. ( 4 )Program Units will settle in BCO common stock on a one-for-one basis and shall be distributed in accordance with the Reporting Person's deferral election either (1) following the Reporting Person's termination of employment with BCO or (2) on a future date selected by the Reporting Person at the time of his or her deferral election.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
