Prospectus Supplement

John Hancock Funds II
Multi-Asset High Income Fund (the fund)

Supplement dated September 25, 2025 to the current Summary Prospectus, as may be supplemented (the Summary Prospectus)

At its meeting held on September 23-25, 2025, the Board of Trustees of the Trust (the Board) approved a change to the principal investment strategies of the fund to allow the fund to invest in Equity Linked Notes.

In connection with the Board action described above, effective September 25, 2025, the following information supplements and supersedes any information to the contrary relating to the fund contained in the current Summary Prospectus:

1. The disclosure under "Principal investment strategies" is revised and restated in its entirety as follows:

The fund has significant flexibility to achieve its investment objective and invests in a broad range of income-producing securities. The fund invests in debt and equity securities, as well as derivative instruments, in the U.S. and developed and emerging markets throughout the world. There is no limit on the number of countries in which the fund may invest, and the fund may focus its investments in a single country or a small group of countries. As attractive investments across asset classes and strategies arise, the manager attempts to capture these opportunities and has wide latitude to allocate the fund's assets among strategies and asset classes. The manager buys and sells securities and investments for the fund based on the manager's views of strategies, sectors, and overall portfolio construction taking into account income generation, risk/return analyses, and relative value considerations.

Under normal market circumstances the fund invests in a broad range of income-producing securities across asset classes as market conditions warrant, but the fund may invest up to 100% of its assets in fixed-income securities and may invest up to 70% of its assets in equity securities from time to time to adjust to prevailing market conditions.

The fund may invest in individual fixed-income securities to the fullest extent permissible. The fund may invest in a portfolio of fixed income securities such as corporate bonds and notes, mortgage-backed securities, asset-backed securities, convertible securities, preferred securities and government obligations. The fund may also invest significantly in below-investment-grade bonds (also known as junk bonds) (e.g., high yield bonds or arbitrage and distressed securities), below-investment-grade bank loans, foreign currency denominated bonds and bonds of emerging market issuers. Direct investments in loans may be illiquid and holding a loan could expose the fund to the risks of being a direct lender. The fund's investment in foreign currency-denominated bonds may be on a currency hedged or unhedged basis. Below-investment-grade bonds acquired by the fund directly or through investing in exchange-traded funds (ETFs) and other underlying funds will generally be in the lower categories of the major rating agencies (BB or lower by S&P Global Ratings (S&P) or Ba or lower by Moody's Investors Service, Inc. (Moody's)) or, if unrated, will be determined by the management team to be of similar quality. Split-rated bonds will be considered to have the higher credit rating. The fund's investment policies are based on credit ratings at the time of purchase. The average portfolio duration of the fund will vary based on the management team's forecast of interest rates and there are no limits regarding portfolio duration or average maturity.

The fund may invest in common stock, preferred stock, securities convertible into common and preferred stock, and non-convertible preferred stock. The fund generally intends to invest in dividend paying stocks. From time to time, the fund may invest in shares of companies through initial public offerings (IPOs). The fund may invest in securities of both U.S. or foreign issuers without limit, which can be U.S. dollar-based or foreign currency-based and may be currency hedged or unhedged. The fund may invest in securities of companies of any market capitalization.

The fund may invest in equity-linked notes (ELNs). ELNs are hybrid structured investments that combine the characteristics of one or more underlying reference securities (usually a single stock, a basket of stocks or a stock index) and a related equity derivative, typically in the form of a note paying a stated interest rate. ELNs are issued by counterparties, including banks, broker-dealers or their affiliates, and are designed to offer a return linked to the underlying securities within the ELN.

The fund also may invest extensively in derivative instruments such as futures, options and swaps, which are generally financial contracts whose value depends upon, or is derived from, the value of an underlying asset, reference rate, or index, and may relate to equity securities, fixed-income securities, interest rates, total return rates, currencies or currency exchange rates, and related hedging purposes. Derivatives may be used to hedge against losses from movements in stock, currency exchange rates or interest rates. Derivatives may be used for non-hedging purposes in order to invest indirectly in securities or financial markets, for duration management which allows the fund to efficiently adjust the average maturity of the
