Olive Street Investment Advisers, LLC (the “Adviser”) has contractually agreed, until at least October 28, 2027, to waive its management fees to the extent management fees to be paid to the Adviser exceed the management fees the Fund is required to pay the Fund’s sub-advisers (i.e., the Adviser does not receive any management fees from the Fund as a result of its waivers). This contractual agreement may not be terminated by the Adviser without the consent of the Board of Trustees (the “Board”) of Bridge Builder Trust (the “Trust”), except that the Adviser may terminate the agreement upon written notice to the Trust, effective as of the end of the expense limitation period ending October 28, 2027, if written notice is provided to the Trust by or before a date agreed to by the Board. Such waivers are not subject to reimbursement by the Fund.

The Net Annual Fund Operating Expenses shown in the fee table may not correlate to the net expense ratio reflected in the Financial Highlights included in this Prospectus or in the Fund’s financial statements. This is because the net expense ratio presented in the Financial Highlights and the financial statements reflects the effect of the Adviser’s management fee waiver during the Fund’s prior fiscal year, while the Net Annual Fund Operating Expenses shown in the fee table reflect the expected effect of the management fee waiver during the Fund’s current fiscal year.
