Represents the number of shares automatically withheld by WEX for the payment of taxes in connection with the vesting of Market Share Units ("MSUs") on March 15, 2026. RSUs vested on March 15, 2026 and each RSU converted into one share of common stock. One-third of RSUs vest each year on the first, second and third anniversaries of the date of grant. Following certification of performance relating to the award (as previously reported by the reporting person), the RSUs vested on March 15, 2026 and each converted into one share of common stock. Each MSU, a form of performance-based restricted share unit, converts into the number of shares of common stock determined by applying a payout factor to the target number of MSUs vesting on a given date. The payout factor is a ratio of the volume weighted average closing price per share over the 10 trading days immediately preceding (and excluding) the vesting date divided by the volume weighted average closing price per share over the 10 trading days immediately preceding (and excluding) the grant date. The minimum payout factor that must be achieved to earn a payout is 60% and the maximum payout factor is 200%. Represents the number of MSUs that vested in the second tranche of the MSU award granted on March 15, 2024, based on a 71.27% payout factor, and were converted into an equal number of shares of common stock. One-third of the MSU award vests on each of the first, second and third anniversaries of the date of grant and converts into shares of common stock based on a payout factor, provided that if the payout factor is not at least 60% on an applicable vesting date, the MSUs eligible to vest on such date will be forfeited. /s/ Andy Schwarcz as attorney-in-fact for Karen Stroup 2026-03-17
