This Supplement contains new and additional information and should be read in connection with your Summary Prospectus and Statutory Prospectus.

At a meeting held on May 19-20, 2026, the Board of Directors (the "Board") of The Hartford Mutual Funds, Inc. (the "Company") approved the conversion of each Acquired Fund listed below under the heading "Acquired Fund" (each an "Acquired Fund") into a corresponding newly created exchange-traded fund listed below under the heading "Corresponding Acquiring Fund" (each an "Acquiring Fund") pursuant to an Agreement and Plan of Reorganization and Liquidation (each a "Conversion" and collectively, the "Conversions"). The table below sets forth each Acquired Fund, the corresponding Acquiring Fund and the anticipated conversion date. 

Acquired Fund	Corresponding Acquiring Fund	Anticipated Conversion Date (or at such earlier or later date as determined by an officer of the Company) ("Conversion Date")
Hartford Climate Opportunities Fund	Hartford Alpha Capture International Value ETF	After the close of trading on October 16, 2026
Hartford International Equity Fund	Hartford Alpha Capture International Equity ETF	After the close of trading on October 23, 2026

Each Acquiring Fund has not commenced operations and will commence operations upon the closing of the Conversion. Each Conversion will be effected through the reorganization of an Acquired Fund into the corresponding Acquiring Fund. Each Acquiring Fund will have the same investment objective and fundamental policies as the corresponding Acquired Fund. Hartford Funds Management Company, LLC, each Acquired Fund's investment manager, will serve as the investment manager to each Acquiring Fund. The chart below summarizes some of the differences in the principal investment strategy of each Acquired Fund and the corresponding Acquiring Fund.  

Conversion	Comparison
Hartford Climate Opportunities Fund Conversion	Unlike the Acquired Fund, the corresponding Acquiring Fund will not focus its investments on securities of issuers that seek opportunities to address or benefit from climate change. The corresponding Acquiring Fund will typically invest a greater percentage of its assets in foreign securities than the Acquired Fund. The corresponding Acquiring Fund will invest at least 65% of its net assets in foreign equity securities. Under normal circumstances, the corresponding Acquiring Fund will invest at least 80% of its assets in securities of value companies. Wellington Management Company LLP will serve as the sub-adviser to the corresponding Acquiring Fund, but Schroder Investment Management North America Inc. and Schroder Investment Management North America Limited will not serve as a sub-adviser and a sub-sub- adviser, respectively, to the corresponding Acquiring Fund. Thomas S. Simon, CFA, FRM, will serve as the portfolio manager to the corresponding Acquiring Fund.
Hartford International Equity Fund Conversion	The Acquired Fund and the corresponding Acquiring Fund will have a similar principal investment strategy. Similar to the Acquired Fund, the corresponding Acquiring Fund will invest at least 65% of its net assets in foreign equity securities and under normal circumstances, the corresponding Acquiring Fund will invest at least 80% of its assets in equity securities. Unlike the Acquired Fund, the corresponding Acquiring Fund will not use a multiple sleeve structure to construct the portfolio and will not invest in emerging markets as part of its principal investment strategy. Wellington Management Company LLP will serve as the sub-adviser to the corresponding Acquiring Fund. Thomas S. Simon, CFA, FRM, will serve as the portfolio manager to the corresponding Acquiring Fund.

Hartford Funds Management Company, LLC believes that the Conversions will provide multiple benefits for shareholders of the Acquired Funds, including (1) lower net expenses taking into consideration expense limitation arrangements that will be in place for at least one year from the Conversion Date; (2) additional trading flexibility with respect to fund shares; (3) increased portfolio holdings transparency; and (4) potential enhanced tax efficiency. Each Conversion is structured to be a tax-free reorganization under the U.S. Internal Revenue Code of 1986, as amended. As a result, Acquired Fund shareholders generally will not recognize a taxable gain (or loss) for U.S. federal income tax purposes as a result of the Conversion (except with respect to cash received or with respect to investors whose shares are redeemed or whose investment is liquidated prior to and in connection with the Conversion, as explained elsewhere in this Supplement).

In connection with each Conversion, eligible shareholders of an Acquired Fund will receive shares of the corresponding Acquiring Fund equal in value to the number of shares of the Acquired Fund they own immediately prior to the Conversion, as well as a cash payment in lieu of any fractional shares of the corresponding Acquiring Fund, which cash payment may be taxable.

Prior to its Conversion, each Acquired Fund plans on engaging in transition management techniques, such as selling portfolio investments, including in order to fund redemption transactions prior to and in connection with the Conversion. During this time, an Acquired Fund may hold a significant amount of cash and cash equivalents and may use futures to equitize cash. During this time, an Acquired Fund may not pursue its investment objective and principal investment strategy. The purchase and sale of securities during this transition period may be made at a disadvantageous time. In addition to transaction costs associated with the repositioning of an Acquired Fund's portfolio, such transactions could result in taxable income or gains to the Acquired Fund, which may result in increased taxable distributions to shareholders holding shares in a taxable account either by the Acquired Fund prior to the Conversion or by the Acquiring Fund after the Conversion. Certain repositioning may occur after the Conversion Date. It is expected that each Acquired Fund will distribute capital gains to shareholders in taxable distributions prior to its Conversion. As a result, shareholders of an Acquired Fund may be required to pay more taxes, or pay taxes sooner, than they would have been required to absent the Conversion. Please consult your tax advisor for information regarding the tax consequences, if any, applicable to your investment.

The information about tax consequences in this Supplement relates to the U.S. federal income tax consequences of the Conversion only. Shareholders should consult their tax advisors about possible federal, state and local tax consequences of the Conversion.

Importantly, in order to be eligible to receive shares of a corresponding Acquiring Fund as part of a Conversion, Acquired Fund shareholders must hold their shares of the Acquired Fund through a brokerage account that can accept shares of a corresponding Acquiring Fund. If Acquired Fund shareholders do not hold their shares of an Acquired Fund through that type of brokerage account, they will not receive shares of the corresponding Acquiring Fund as part of the Conversion. For Acquired Fund shareholders that do not currently hold their shares of an Acquired Fund through a brokerage account that can hold shares of the corresponding Acquiring Fund, please see the Q&A that follows for additional actions that such Acquired Fund shareholders must take to receive shares of the corresponding Acquiring Fund as part of the Conversion. No further action is required for Acquired Fund shareholders that hold shares of an Acquired Fund through a brokerage account that can hold shares of the corresponding Acquiring Fund.

Completion of a Conversion is subject to a number of conditions under the Agreement and Plan of Reorganization and Liquidation, but shareholders of an Acquired Fund are not required to approve a Conversion. Existing Acquired Fund shareholders will receive an information statement/prospectus describing in detail both the Conversion and the corresponding Acquiring Fund, and summarizing the Board's considerations in approving the Conversion.

Effective as of the close of business on June 30, 2026, the following changes to each Acquired Fund will take effect: (1) the Acquired Fund will be closed to new investors with limited exceptions; (2) new accounts may no longer be established directly through the Acquired Fund's transfer agent; (3) no contingent deferred sales charge ("CDSC") will be imposed on redemptions of the Class A or Class C shares; (4) no sales charges will be imposed on purchases of Class A shares; (5) any current Letter of Intent (LOI) under which Class A shares of the Acquired Fund were purchased will be considered completed; (6) no finders' fees or upfront commissions will be paid to financial intermediaries on Class A or Class C shares; and (7) distribution and service (Rule 12b-1) fees on all applicable Acquired Fund share classes will be waived.

In anticipation of the Conversions, purchase orders, exchange orders, and redemption orders will only be accepted by the Acquired Funds until the dates indicated below: 

Acquired Fund	Final Date to Purchase Fund Shares for Existing Shareholders	Final Date to Redeem Fund Shares or Exchange Fund Shares for another Hartford Mutual Fund
Hartford Climate Opportunities Fund	October 9, 2026	October 15, 2026
Hartford International Equity Fund	October 16, 2026	October 22, 2026

IMPORTANT NOTICE ABOUT YOUR FUND ACCOUNT
QUESTIONS AND ANSWERS

The following is a brief Q&A that provides information to help you to determine if you need to take action with respect to your shareholder account prior to a Conversion.

A. If you hold your shares of an Acquired Fund in a brokerage account that permits you to purchase securities traded in the stock market, such as exchange-traded funds (ETFs) or other types of stocks, then you will be eligible to receive shares of the corresponding Acquiring Fund in the Conversion. No further action is required.

Q. What types of shareholder accounts cannot receive shares of an Acquiring Fund as part of a Conversion and what will happen if I have such an account?

A. The following account types cannot hold shares of ETFs:

Non-Accommodating Brokerage Accounts. If you hold your shares of an Acquired Fund in a brokerage account with a financial intermediary that only allows you to hold shares of mutual funds in the account, you will need to contact your financial intermediary to set up a brokerage account that permits investments in ETF shares. If such a change is not made before the Conversion, you will not receive shares of the corresponding Acquiring Fund as part of the Conversion. Instead, your investment will be liquidated and you will receive cash equal in value to the NAV of your Acquired Fund shares as of the Conversion Date (as set forth in the chart above), which is a taxable event.

Retirement Accounts Held with Financial Intermediary. If you hold your shares of an Acquired Fund through an individual retirement account ("IRA") or group retirement plan whose plan sponsor does not have the ability to hold shares of ETFs on its platform, you may need to redeem your shares prior to the Conversion or, if applicable, your financial intermediary may transfer your investment in an Acquired Fund to a different investment option prior to the Conversion.

Direct Held Retirement and Qualified Accounts. If you own shares of an Acquired Fund in a directly held retirement account, such as an IRA, or Coverdell account through Hartford Funds and maintained by UMB Bank, n.a. (a "Direct Held Qualified Account"), we encourage you to (i) transfer your Acquired Fund shares to a brokerage account that can accept shares of the Acquiring Fund (see "Direct Accounts" below for more information) prior to the Conversion or (ii) provide instructions for the exchange or reinvestment of Acquired Fund shares prior to the Conversion. If a Direct Held Qualified Account shareholder does not provide instructions prior to the Conversion, your Acquired Fund shares will -    without any further notice -    be automatically exchanged on the Conversion Date (as set forth in the chart above) for shares of The Hartford Short Duration Fund ("Short Duration Fund"). This automatic exchange provision is disclosed in the applicable custodial agreement and is applicable to each Direct Held Qualified Account. The Short Duration Fund has a different investment objective, principal investment strategy and principal risks than an Acquired Fund. If you do not wish for your Acquired Fund shares to be automatically exchanged for shares of the Short Duration Fund, you must contact an Acquired Fund at 1-888-843-7824 before the Conversion Date. If an Acquired Fund does not receive any instructions prior to the Conversion Date, your Acquired Fund shares held in the Direct Held Qualified Account will be exchanged for shares of the same class of the Short Duration Fund. More information will be provided in a separate letter to Direct Held Qualified Account shareholders.

Direct Accounts. If you hold your shares of an Acquired Fund in an account directly (i.e. not plan level or an omnibus position) with the Acquired Fund's transfer agent, Hartford Administrative Services Company, you should transfer your shares of the Acquired Fund to a brokerage account that can accept shares of the corresponding Acquiring Fund prior to the Conversion. If such a change is not made prior to the Conversion, you will not receive shares of the corresponding Acquiring Fund as part of the Conversion. Instead, your investment will be liquidated and you will receive cash equal in value to the NAV of your Acquired Fund shares as of the Conversion Date (as set forth in the chart above), which is a taxable event.
