Important information regarding your distributions

We are providing shareholders of the John Hancock Preferred Income Fund with information concerning the portion of the distributions made for August 29, 2025, that was from a source other than net investment company book income. No action is required on your part.

The amounts and sources of distributions reported in this notice are estimates, are not being provided for tax reporting purposes and may later be determined to be from taxable net investment income, short-term gains, long-term gains (to the extent permitted by law), and return of capital. The actual amounts and sources for tax reporting purposes will depend upon the Fund’s investment experience during the remainder of the fiscal year and may be subject to changes based on tax regulations. The Fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.
