John Hancock Funds II

Prospectus Supplement

John Hancock Funds II
Equity Income Fund (the fund)

Supplement dated September 24, 2026 to the current Prospectus, as may be supplemented (the Prospectus)

At its meeting held on September 22-24, 2026, the Trust’s Board of Trustees approved a reduction in the fund’s management fee to be retroactively effective as of August 1, 2026 (the Effective Date). As a result, the information in the “Annual fund operating expenses” table and the “Expense example” table in the “Fund summary” section is amended and restated as follows to reflect the fund’s revised management fee as of the Effective Date:

Annual fund operating expenses (%) (expenses that you pay each year as a percentage of the value of your investment)	A	C
Management fee	0.67 1	0.67 1
Distribution and service (Rule 12b-1) fees	0.30	1.00
Other expenses	0.18	0.18
Total annual fund operating expenses	1.15	1.85
Contractual expense reimbursement	-0.01 2	-0.01 2
Total annual fund operating expenses after expense reimbursements	1.14	1.84

“Management fee” has been restated to reflect the contractual management fee schedule effective August 1, 2026.

The advisor contractually agrees to waive a portion of its management fee and/or reimburse expenses for the fund and certain other John Hancock funds according to an asset level breakpoint schedule that is based on the aggregate net assets of all the funds participating in the waiver or reimbursement, including the fund (the participating portfolios). This waiver equals, on an annualized basis, 0.0100% of that portion of the aggregate net assets of all the participating portfolios that exceeds $75 billion but is less than or equal to $125 billion; 0.0125% of that portion of the aggregate net assets of all the participating portfolios that exceeds $125 billion but is less than or equal to $150 billion; 0.0150% of that portion of the aggregate net assets of all the participating portfolios that exceeds $150 billion but is less than or equal to $175 billion; 0.0175% of that portion of the aggregate net assets of all the participating portfolios that exceeds $175 billion but is less than or equal to $200 billion; 0.0200% of that portion of the aggregate net assets of all the participating portfolios that exceeds $200 billion but is less than or equal to $225 billion; and 0.0225% of that portion of the aggregate net assets of all the participating portfolios that exceeds $225 billion. The amount of the reimbursement is calculated daily and allocated among all the participating portfolios in proportion to the daily net assets of each participating portfolio. During its most recent fiscal year, the fund’s reimbursement amounted to 0.01% of the fund’s average daily net assets. This agreement expires on July 31, 2027, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.

Expense example

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. Please see below a hypothetical example showing the expenses of a $10,000 investment for the time periods indicated and then, except as shown below, assuming you sell all of your shares at the end of those periods. The example assumes a 5% average annual return and that fund expenses will not change over the periods. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

	Shares Sold		Shares Not Sold
Expenses ($)	A	C	C
1 year	610	287	187
3 years	846	581	581
5 years	1,100	1,000	1,000
10 years	1,827	1,985	1,985

Additionally, as of the Effective Date, the table related to the fund’s management fee schedule and the paragraph preceding the table in the “Fund details” section, under the heading “Who’s who—Management fee,” are amended and restated as follows:

Management fee

The fund pays the advisor a management fee for its services to the fund. The advisor in turn pays the fees of the subadvisor. The management fee is stated as an annual percentage of the aggregate net assets of the fund (together with the assets of any other applicable fund identified in the advisory agreement) determined in accordance with the following schedule, and that rate is applied to the average daily net assets of the fund. The fee schedule that follows became effective August 1, 2026.

Aggregate Net Assets	Annual Rate

Between $100 million and $200 million#	0.775%

# When aggregate net assets exceed $200 million on any day, the annual rate of advisory fee for that day is 0.775% on the first $200 million of aggregate net assets.

## When aggregate net assets exceed $500 million on any day, the annual rate of advisory fee for that day is 0.750% on the first $500 million of aggregate net assets and 0.725% on the amount above $500 million.

### When aggregate net assets exceed $1 billion on any day, the annual rate of advisory fee for that day is 0.725% on the first $1 billion of aggregate net assets.

###### When aggregate net assets exceed $3 billion on any day, the annual rate of advisory fee for that day is 0.670% on the first $3 billion of aggregate net assets.

Additionally, as of the Effective Date, the following disclosure is added after the first paragraph under the heading “Who’s who—Additional information about fund expenses,” as follows:

The advisor contractually agrees to reduce its management fee or, if necessary, make payment to Class A shares in an amount equal to the amount by which expenses of Class A shares exceed 1.14% of average daily net assets attributable to the class. For purposes of this agreement, “expenses of Class A shares” means all expenses of the class (including fund expenses attributable to the class), excluding (a) taxes, (b) brokerage commissions, (c) interest expense, (d) litigation and indemnification expenses and other extraordinary expenses not incurred in the ordinary course of the fund’s business, (e) underlying fund expenses (acquired fund fees), (f) short dividend expense, and (g) contingent tax reclaim recovery expenses. This agreement expires on December 31, 2026, unless renewed by mutual agreement of the fund and the advisor based upon a determination that this is appropriate under the circumstances at that time.
