Proxy Statement Mailed to Shareholders of The Hartford Growth Opportunities Fund

A Special Meeting of Shareholders (the “Meeting” or the “Shareholder Meeting”) of The Hartford Growth Opportunities Fund (the “Fund”), a series of The Hartford Mutual Funds II, Inc. (the “Company”), will take place on December 13, 2023 at 10:00 a.m. Eastern Time at the offices of Hartford Funds Management Company, LLC (“HFMC”), 690 Lee Road, Wayne, Pennsylvania 19087. The proxy materials were provided to shareholders who owned shares of the Fund as of the close of business on September 25, 2023.

What Proposal will shareholders be asked to consider at the upcoming Meeting?

Description of Proposal

To reclassify the Fund from a diversified investment company to a non-diversified investment company and eliminate a related fundamental diversification policy, effective on or about March 1, 2024

What are shareholders being asked to vote on?

At a meeting held on September 6-7, 2023, the Board of Directors of the Company (“Board”), including all of the independent directors, unanimously approved reclassifying the Fund’s diversification status from diversified to non-diversified and eliminating a related fundamental diversification policy, subject to the approval of the Fund’s shareholders.

As a diversified fund, the Fund is limited in its ownership of securities of any single issuer. If approved, the Fund would be permitted to invest a larger percentage of its assets in a smaller number of issuers, as described in greater detail below. Classification as a non-diversified fund will give the Fund’s portfolio management team increased flexibility to invest a greater percentage of the Fund’s assets in any one issuer and in fewer issuers overall. HFMC believes reclassifying the Fund from diversified to non-diversified is in the best interests of the Fund and its shareholders because it provides the Fund’s portfolio managers with increased investment flexibility and potential for better investment performance over time.

What is the difference between diversified funds and non-diversified funds?

Under the Investment Company Act of 1940, as amended (the “1940 Act”), an investment company must be classified as diversified or non-diversified. A fund’s diversification classification governs the amount of its assets a fund can invest in any one issuer. The Fund is currently classified as a diversified fund and must, therefore, operate in compliance with the 1940 Act diversification requirements, which strictly limit how much the Fund can invest in a single issuer. If the proposal is approved, the Fund would be permitted to invest a larger percentage of its assets in a smaller number of issuers.

Classification as a non-diversified fund will provide the Fund’s portfolio management team with the flexibility to invest a greater percentage of the Fund’s assets in fewer issuers or in any one issuer which may, in turn, provide the potential for better investment performance over time. For these reasons, HFMC believes that reclassifying the Fund as non-diversified is in the best interests of the Fund and its shareholders.

Will the Fund’s risk profile change if it is reclassified as non-diversified under the 1940 Act?

Yes. Notwithstanding the increased investment flexibility and the potential for improved investment performance over time, a non-diversified fund typically presents a greater degree of investment risk due to its ability to invest a greater percentage of its assets in a single issuer and in fewer issuers overall. Because a non-diversified fund can invest more of its assets in a smaller number of issuers, it may be more exposed to the risks associated with an individual issuer than a fund that invests more broadly across many issuers. For example, if the proposal is approved and the Fund takes advantage of the increased flexibility afforded to it, poor performance by a single large holding of the Fund would adversely affect the Fund’s performance to a greater extent than if the Fund were invested in a larger number of issuers. As a result, as a non-diversified fund, the Fund’s share price may fluctuate more than that of a similar fund that is more broadly diversified.

A non-diversified fund may from time to time temporarily operate in a diversified manner without losing its non-diversified status and, as a result, at times, if the proposal is approved, the Fund may not take advantage of the greater flexibility afforded to a non-diversified fund.

If shareholders approve the proposal, when will the change take effect?

If the proposal is approved by shareholders of the Fund at the Shareholder Meeting, it is expected to become effective on or about March 1, 2024 in connection with the Fund’s annual update of its registration statement.

Who pays for the costs involved with the proxy?

All costs of the Shareholder Meeting and the proxy campaign will be paid for by the Fund.

Does the Board recommend that shareholders approve the Proposal?

The Board of Directors of the Company, including all of the Company’s independent directors, recommend that shareholders of the Fund vote “FOR” the proposal to change the Fund’s classification from diversified to non-diversified and to eliminate the Fund’s related fundamental diversification policy.
