Fund reorganization
At a meeting held on June 18, 2026, the Board of Trustees of Columbia Funds Series Trust approved an Agreement and Plan of Reorganization pursuant to which the Fund will transfer all of its assets and liabilities to Columbia Cornerstone Growth Fund (the Acquiring Fund) in exchange for shares of the Acquiring Fund (the Reorganization). Pursuant to applicable law (including the Investment Company act of 1940), the Reorganization does not require shareholder approval. The Reorganization is expected to close on or about November 20, 2026 and is expected to qualify as a tax-free reorganization for U.S. federal income tax purposes.
