On March 19, 2026, the Fund's Board of Trustees approved the Russell 1000® Value Index as an additional performance benchmark for the Fund to provide an additional performance comparison. As a result, effective immediately, the last sentence in the first paragraph and the Average Annual Total Returns table under the heading "Performance Information" in the Summary of Columbia U.S. Equity Income ETF section in the prospectus and in the Summary Prospectus are hereby superseded and replaced with the following:

The table below the bar chart compares the Fund’s returns for the periods shown with a broad measure of market performance, as well as two additional measures of performance for markets in which the Fund may invest and a prior benchmark for a one-year transition period.
