On April 7, 2022, CIBC shareholders approved a
two-for-one
share split (Share Split) of CIBC’s issued and outstanding common shares. Each shareholder of record at the close of business on May 6, 2022 (Record Date) received one additional share on May 13, 2022 (Payment Date) for every one share held on the Record Date. All common share numbers and per common share amounts have been adjusted to reflect the Share Split as if it was retroactively applied to the beginning of 2022.
