Fund profile
As filed in the prospectus · 2025 Q4
Columbia Select Mid Cap Growth Fund (the Fund) seeks significant capital appreciation by investing, under normal market conditions, at least 80% of its net assets (plus any borrowings for investment purposes) in stocks of companies with a market capitalization, at the time of initial purchase, equal to or less than the largest stock in the Russell Midcap Index.
The fund invests in common stocks of mid-cap companies within the Russell Midcap Index range, selected for potential long-term above-average earnings growth, and typically holds a focused portfolio of fewer securities than peers. The fund may emphasize particular sectors, invest in special situations including IPOs and restructurings, and allocate up to 20% of assets to foreign securities. Because the fund employs a focused investing style with concentrated holdings, performance depends heavily on the success of a limited number of positions. The fund may trade portfolio securities frequently.

Portfolio growth profile
How much of the fund’s stock holdings are in fast-growing companies · as of 2026 Q2
Share of the fund’s equity (by value) in companies whose trailing five-year revenue — or net-income — growth ranks in the top 25% of U.S. public companies. Foreign and newly-listed holdings are excluded, so the figure covers only part of the book. From SEC filings — not investment advice. How we measure this.

May 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
