Fund profile
As filed in the prospectus · 2025 Q4
The investment objective of Bridge Builder Small/Mid Cap Growth Fund (the Fund or the Small/Mid Cap Growth Fund) is to provide capital appreciation.
The fund combines the investment strategies of seven sub-advisers, each employing distinct approaches to select small and mid-capitalization securities: one sub-adviser tracks the Russell MidCap Growth and Russell 2000 Growth indices, while the others use fundamental analysis, quantitative screening, or both to identify companies with growth potential at attractive valuations. Because the fund's performance depends on the security selections and execution of multiple sub-advisers with different methodologies, results will reflect the aggregate of their individual decisions and the allocation of assets among them.

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.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
May 2026 and Jun 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.

Based on what filers reported; a filer that never reported a flag also reads as none.
