Dear Shareholder:

You may have received several letters relating to the upcoming Special Meeting of Shareholders (the “Meeting”) of The Hartford Growth Opportunities Fund (the “Fund”), scheduled for December 13, 2023. An important proposal will be presented at the Meeting as outlined on the attached proxy card. The Board of Directors of the Fund recommend shareholders approve the proposal.

WHAT ARE SHAREHOLDERS BEING ASKED TO VOTE ON?

Proposal 1: To approve reclassifying the Fund from a diversified investment company to a non-diversified investment company and eliminating a related fundamental diversification policy.

✓ The Fund is currently classified as a diversified fund and must, therefore, operate in compliance with the diversification requirements under the Investment Company Act of 1940 (as amended), 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, Hartford Funds Management Company, LLC, the Fund’s investment manager, believes that reclassifying the Fund as non-diversified is in the best interests of the Fund and its shareholders.

Additional information regarding the Meeting and the proposal can be found in the proxy statement. For your convenience, the proxy statement is also located online at https://vote.proxyonline.com/Hartford/docs/GrowthOppsMeeting2023.pdf
