(2)

Hartford Funds Management Company, LLC (the “Investment Manager”) has contractually agreed to reimburse expenses (exclusive of taxes, interest expenses, brokerage commissions, acquired fund fees and expenses and extraordinary expenses) to the extent necessary to limit total annual fund operating expenses as follows: 0.69% (Class A), 1.44% (Class C), 0.46% (Class I), and 0.39% (Class F). This contractual arrangement will remain in effect until February 28, 2026 unless the Board of Directors of The Hartford Mutual Funds, Inc. approves its earlier termination.

Example. The example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then, except as shown below, redeem all of your shares at the end of those periods. The example also assumes that:

●

Your investment has a 5% return each year

●

The Fund’s operating expenses remain the same (except that the example reflects the fee waiver and/or expense reimbursement arrangement reflected in the table above for only the first year)

●

You reinvest all dividends and distributions.

Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Share Classes	Year 1	Year 3	Year 5	Year 10
A	$517	$716	$932	$1,551
C	$247	$548	$975	$2,165
I	$47	$213	$393	$914
F	$40	$184	$341	$797

If you did not redeem your shares:

$147

$548

$975

$2,165

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal year ended October 31, 2024, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGY. The Fund seeks to achieve its investment objective by investing in investment grade municipal securities and non-investment grade municipal securities (known as “junk bonds”) that the sub-adviser, Wellington Management Company LLP (“Wellington Management”), considers to be attractive from a yield perspective while considering total return. Under normal circumstances, the Fund will invest at least 80% of its net assets in municipal securities that pay interest exempt from federal income tax. The Fund may invest up to 20% of its net assets in non-investment grade municipal securities. The Fund may invest in securities that produce income subject to income tax, including the Alternative Minimum Tax. The Fund will generally hold a diversified portfolio of investments across states and sectors, although the Fund is not required to invest in all states and sectors at all times.

The Fund normally will maintain a dollar weighted average duration of 3 years or less. Duration is a measure of the sensitivity of a fixed income security’s price to changes in interest rates. The Fund’s average duration measure incorporates a bond’s yield, coupon, final maturity, and the effect of derivatives that may be used to manage the Fund’s interest rate risk.

Wellington Management’s portfolio construction process combines a top-down strategy, bottom-up fundamental research and comprehensive risk management. Bottom-up, internally generated, fundamental research attempts to identify relative value among sectors, within sectors, and between individual securities.

PRINCIPAL RISKS. The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any fund, there is no guarantee that the Fund will achieve its investment objective.

Market Risk – Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities of a company may decline in value due to its financial prospects and activities, including certain operational impacts, such as data breaches and cybersecurity attacks. Securities may also decline in value due to general market and economic movements and trends, including adverse changes to credit markets, or as a result of other events such as geopolitical events, natural disasters, or widespread pandemics (such as COVID-19) or other adverse public health developments.

Municipal Securities Risk – Municipal securities risks include the possibility that the issuer may be unable to pay interest or repay principal on a timely basis or at all, the relative lack of information about certain issuers of municipal securities, and the possibility of future legislative changes which could affect the market for and value of municipal securities. In addition, state or local political or economic conditions and developments can adversely affect the

securities issued by state and local governments. The value of the municipal securities owned by the Fund also may be adversely affected by future changes in federal or state income tax laws, including tax rate reductions or the determination that municipal securities are subject to taxation.

Interest Rate Risk – The risk that your investment may go down in value when interest rates rise, because when interest rates rise, the prices of bonds and fixed rate loans fall. A wide variety of factors can cause interest rates to rise, including central bank monetary policies and inflation rates. Generally, the longer the maturity of a bond or fixed rate loan, the more sensitive it is to this risk. Falling interest rates also create the potential for a decline in the Fund’s income. These risks are greater during periods of rising inflation. Volatility in interest rates and in fixed income markets may increase the risk that the Fund’s investment in fixed income securities will go down in value. Actions taken by the Federal Reserve Board or foreign central banks to stimulate or stabilize economic growth, such as decreases or increases in short-term interest rates, may adversely affect markets, which could, in turn, negatively impact Fund performance.

Credit Risk – Credit risk is the risk that the issuer of a security or other instrument will not be able to make principal and interest payments when due. Changes in an issuer’s financial strength, credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation. Periods of market volatility may increase credit risk.

Call Risk – Call risk is the risk that an issuer, especially during a period of falling interest rates, may redeem a security by repaying it early, which may reduce the Fund’s income if the proceeds are reinvested at lower interest rates.

High Yield Investments Risk – High yield investments rated below investment grade (also referred to as “junk bonds”) are considered to be speculative and are subject to heightened credit risk, which may make the Fund more sensitive to adverse developments in the U.S. and abroad. Lower rated debt securities generally involve greater risk of default or price changes due to changes in the issuer’s creditworthiness than higher rated debt securities. The market prices of these securities may fluctuate more than those of higher rated securities and may decline significantly in periods of general economic difficulty. There may be little trading in the secondary market for particular debt securities, which may make them more difficult to value or sell.

Active Investment Management Risk – The risk that, if the sub-adviser’s investment strategy does not perform as expected, the Fund could underperform its peers or lose money. Although the sub-adviser considers several factors when making investment decisions, the sub-adviser may not evaluate every factor prior to investing in an issuer, and the sub-adviser may determine that certain factors are more significant than others.

Liquidity Risk – The risk that the market for a particular investment or type of investment is or becomes relatively illiquid, making it difficult for the Fund to sell that investment at an advantageous time or price. Illiquidity may be due to events relating to the issuer of the securities, market events, rising interest rates, economic conditions or investor perceptions. Illiquid securities may be difficult to value and their value may be lower than the market price of comparable liquid securities, which would negatively affect the Fund’s performance.

Large Shareholder Transaction Risk – The Fund may experience adverse effects when certain large shareholders redeem or purchase large amounts of shares of the Fund. Such redemptions may cause the Fund to sell securities at times when it would not otherwise do so or borrow money (at a cost to the Fund), which may negatively impact the Fund’s performance and liquidity. Similarly, large purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs.

The Fund is subject to certain other risks. For more information regarding risks and investments, please see “Additional Information Regarding Investment Strategies and Risks” and “More Information About Risks” in the Fund’s statutory prospectus.

PAST PERFORMANCE. The performance information indicates the risks of investing in the Fund. Keep in mind that past performance (before and after taxes) does not indicate future results. Updated performance information is available at hartfordfunds.com. The returns for the Fund in the bar chart and table:

●

Assume reinvestment of all dividends and distributions

●

Reflect fee waivers and/or expense limitation arrangements, if any. Absent any applicable fee waivers and/or expense limitation arrangements, performance would have been lower.

The bar chart:

●

Shows how the Fund’s total return has varied from year to year

●

Returns do not include sales charges. If sales charges were reflected, returns would have been lower

●

Shows the returns of Class A shares. Returns for the Fund’s other classes differ only to the extent that the classes do not have the same expenses.

Total returns by calendar year (excludes sales charges)

During the periods shown in the chart above:	Returns	Quarter Ended
Best Quarter Return	3.19%	December 31, 2023
Worst Quarter Return	-3.48%	March 31, 2022

Average Annual Total Returns. The table below shows returns for the Fund over time compared to those of two indices. The Bloomberg Municipal Bond Short 1-5 Year Index serves as the Fund’s performance index because the Fund’s investment manager believes it is more representative of the Fund’s investment strategy. The Bloomberg Municipal Bond Index serves as the Fund’s regulatory index and provides a broad measure of market performance. After-tax returns, which are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes, are shown only for Class A shares and will vary for other classes. Actual after-tax returns, which depend on an investor’s particular tax situation, may differ from those shown and are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Average annual total returns for periods ending December 31, 2024 (including sales charges)
