Statement of Additional Information Supplement

**John Hancock Bond Trust (the Trust)**

**John Hancock High Yield Fund (the fund)**

**Supplement dated June 25, 2026 to the current Statement of Additional Information, as may be supplemented (the SAI)**

At its meeting held on June 23-25, 2026, the Trust's Board of Trustees (the Board) approved a new sub-subadvisory agreement between Manulife Investment Management (US) LLC ("Manulife IM (US)"), the fund's subadvisor, and CQS (US), LLC with respect to the fund, effective on or about June 25, 2026 (the Effective Date).

Also effective on the Effective Date, Manulife IM (US) entered into a participating affiliates agreement with CQS (UK) LLP, an affiliate of Manulife IM (US), with respect to the fund.

Accordingly, as of the Effective Date, the "INVESTMENT MANAGEMENT ARRANGEMENTS AND OTHER SERVICES" section, under the heading "Subadvisory Agreement," the sections entitled "Duties of the Subadvisor" and "Subadvisory Fees" are restated as follows:

**Duties of the Subadvisor.** Under the terms of each of the current subadvisory agreements, including multiple sub-subadvisory arrangements (each a "Subadvisory Agreement" and collectively, the "Subadvisory Agreements"), the subadvisor manage the investment and reinvestment of the assets of the funds, subject to the supervision of the Board and the Advisor. In addition, for a fund with a sub-subadvisory arrangement as indicated in its Prospectus, the activities of the sub-subadvisor are subject to the supervision of that fund's subadvisor. Each subadvisor formulates a continuous investment program for each such fund consistent with its investment objectives and policies outlined in the Prospectus. Each subadvisor implements such programs by purchases and sales of securities and regularly reports to the Advisor and the Board with respect to the implementation of such programs. Each subadvisor, at its expense, furnishes all necessary investment and management facilities, including salaries of personnel required for it to execute its duties, as well as administrative facilities, including bookkeeping, clerical personnel, and equipment necessary for the conduct of the investment affairs of the assigned funds. Additional information about the funds' portfolio managers, including other accounts managed, ownership of fund shares, and compensation structure, can be found at Appendix B to this SAI.

The Advisor has delegated to the subadvisor the responsibility to vote all proxies relating to the securities held by the funds. See "Other Services — Proxy Voting" below, for additional information.

**Subadvisory Fees.** As compensation for its services, each subadvisor receives fees from the Advisor computed separately for each fund. In respect of a sub-subadvisory agreement, the fees are paid by the subadvisor to the entity providing the sub-subadvisory services described below.

Also, as of the Effective Date, the "INVESTMENT MANAGEMENT ARRANGEMENTS AND OTHER SERVICES" section, under the heading "Subadvisory Agreement," after the section entitled "Subadvisory Fees" is supplemented as follows:

**Subadvisory Arrangement for High Yield Fund.** In rendering investment advisory services to High Yield Fund, Manulife Investment Management (US) LLC ("Manulife IM (US)"), the subadvisor to High Yield Fund, may use the portfolio management, research and other resources of CQS (UK) LLP, an affiliate of Manulife IM (US) (the "Participating Affiliate"). The Participating Affiliate is not registered with the SEC as an investment advisor under the Advisers Act. Manulife IM (US) has entered into separate memoranda of understanding and supervisory agreement (the "Participating Affiliate Agreement") with the Participating Affiliate pursuant to which the Participating Affiliate is considered a participating affiliate of the subadvisor as that term is used in relief granted by the staff of the SEC allowing U.S. registered investment advisors to use portfolio management or research resources of advisory affiliates subject to the supervision of a registered advisor. Investment professionals from the Participating Affiliate may render portfolio management, research and other services to High Yield Fund under the Participating Affiliate Agreement and are subject to supervision by Manulife IM (US).

**Sub-Subadvisory Arrangements**. Under a sub-subadvisory arrangement, the sub-subadvisor provides certain investment advisory services to the fund's subadvisor for the benefit of the fund. In each case, the subadvisor pays the sub-subadvisor, as full compensation for all services provided under the sub-subadvisory arrangement, a portion of its subadvisory fee. The Trust does not incur any expenses in connection with any sub-subadvisor's services other than the advisory fee.
