I. ADDITION OF TRUSTEES TO BOARD OF TRUSTEES

Effective March 21, 2023, the SAI is hereby amended to add Deanna A. Mankins and James D. Caldwell as members of the Board of Trustees of GuideStone Funds. Each of Ms. Mankins and Mr. Caldwell will be an independent trustee, as each individual will not be an “interested person” of the Trust, as the term “interested person” is defined in Section 2(a)(19) of the Investment Company Act of 1940, as amended.

Under the heading “Management of the Funds,” on page 61, the first two paragraphs, entitled The Board of Trustees and Board Role in Risk Oversight, respectively, are deleted in their entirety and replaced with the following:

The Board of Trustees. The primary responsibility of the Board of Trustees is to represent the interests of the shareholders of the Trust and to oversee the management of the Trust. The Board meets at least quarterly to review the investment performance of each Fund and other operational matters, including policies and procedures with respect to compliance with regulatory and other requirements. Only shareholders of the Trust, by a vote of a majority of the outstanding shares, may fill vacancies or otherwise elect a Trustee. The Board is comprised of 10 individuals, two of whom are considered “interested” Trustees as defined by the 1940 Act due to their positions on the Board of Trustees of GuideStone Financial Resources. The remaining Trustees are deemed not to be “interested persons” of the Trust as defined by Section 2(a)(19) of the 1940 Act (“Independent Trustees”).

Board Role in Risk Oversight. The Board’s role with respect to the Trust is oversight. As is the case with virtually all investment companies (as distinguished from operating companies), service providers to the Trust, primarily the Adviser and its affiliates, have responsibility for the day-to-day management of the Funds, which includes responsibility for risk management. Examples of prominent risks include investment risk, liquidity risk, regulatory and compliance risks, operational risks, accounting risks, valuation risks, service provider risks and legal risks. As part of its oversight role, the Board, acting at its scheduled meetings, or the Chairman, acting between Board meetings, interacts with and receives reports from senior personnel of service providers, including the Adviser’s Chief Investment Officer (or a senior representative of the Adviser) and portfolio management personnel. The Board receives periodic presentations and reports from the Risk Manager and senior personnel of the Adviser or its affiliates regarding risk management generally, as well as periodic presentations regarding specific operational, compliance or investment areas such as accounting, administration, anti-money laundering, cybersecurity, derivatives, liquidity, valuation, personal trading, investment research and securities lending. The Board also receives reports from counsel to the Trust and the Independent Trustees’ own independent legal counsel regarding regulatory compliance and governance matters. The Board interacts with and receives reports from the Chief Compliance Officer (“CCO”) of the Trust, and in connection with each scheduled meeting, the Independent Trustees meet separately from the Adviser and Trust management with the CCO of the Trust and independent legal counsel, on regulatory compliance matters. The Board’s oversight role does not make the Board a guarantor of the Trust’s investments or activities.
