John Hancock Tax-Advantaged Dividend Income Fund Notice to Shareholders - Sources of Distribution Under Section 19(a)

BOSTON, Sept. 30, 2026 /PRNewswire/ -- John Hancock Tax-Advantaged Dividend Income Fund (NYSE: HTD) (the "Fund"), a closed-end fund managed by John Hancock Investment Management LLC and subadvised by Manulife Investment Management (US) LLC, announced today sources of its monthly distribution of $0.1580 per share paid to all shareholders of record as of September 11, 2026, pursuant to the Fund's managed distribution plan. This press release is issued as required by an exemptive order granted to the Fund by the U.S. Securities and Exchange Commission.  

Notification of Sources of Distribution

This notice provides shareholders of the John Hancock Tax-Advantaged Dividend Income Fund (NYSE: HTD) with important information concerning the distribution declared on September 1, 2026, and payable on September 30, 2026. No action is required on your part.

Distribution Period: September 2026

Distribution Amount Per Common Share: $0.1580

The following table sets forth the estimated sources of the current distribution, payable September 30, 2026, and the cumulative distributions paid this fiscal year to date from the following sources: net investment income; net realized short term capital gains; net realized long term capital gains; and return of capital or other capital source. All amounts are expressed on a per common share basis and as a percentage of the distribution amount.

You should not draw any conclusions about the Fund's investment performance from the amount of this distribution or from the terms of the Fund's managed distribution plan.

The Fund estimates that it has distributed more than its income and net realized capital gains; therefore, a portion of your distribution may be a return of capital.  A return of capital may occur, for example, when some or all of the money that you invested in the Fund is paid back to you.  A return of capital distribution does not necessarily reflect the Fund's investment performance and should not be confused with "yield" or "income."

The amounts and sources of distributions reported in this Notice are only estimates and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the Fund's investment experience during the remainder of its 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.

The Fund has declared the September 2026 distribution pursuant to the Fund's managed distribution plan (the "Plan").  Under the Plan, the Fund makes fixed monthly distributions in the amount of $0.1580 per share, which will continue to be paid monthly until further notice.

Statements in this press release that are not historical facts are forward-looking statements as defined by the United States securities laws. You should exercise caution in interpreting and relying on forward-looking statements because they are subject to uncertainties and other factors which are, in some cases, beyond the Fund's control and could cause actual results to differ materially from those set forth in the forward-looking statements.
