(the “Adviser”), the Board of Trustees of HSBC Funds (the “Trust”) has approved: (i) the conversion of the outstanding Intermediary Class Shares of the HSBC U.S. Government Money Market Fund (the “Government Fund”) and the HSBC U.S. Treasury Money Market Fund (the “Treasury Fund,” and with the Government Fund, the “Funds”) into Intermediary Service Class Shares of the same respective Fund; (ii) the termination of the Intermediary Class Shares of the Funds; and (iii) the elimination of the shareholder servicing fees for Intermediary Service Class Shares and Class P Shares of the Funds. These changes will take effect on or about September 11, 2026, or on such other date as the officers of the Trust determine (the “Effective Date”). Effective immediately, the Funds will no longer sell Intermediary Class Shares to new investors or existing shareholders (except through reinvested dividends), including through exchanges into each Fund. Investors may continue to redeem shares of each Fund prior to the Effective Date. As a result, effective on the Effective Date, the following changes are being made to the Prospectus and SAI: 1. All references to Intermediary Class Shares of the Government and Treasury Funds are eliminated. 2.
