**Example**. *This example is intended to help you compare the cost of investing in the Value 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 redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:*

| | | | | |
|:---|:---|:---|:---|:---|
|  | **One<br> Year** | **Three<br> Years** | **Five<br> Years** | **Ten<br> Years** |
| Investor Class Shares | $111 | $347 | $601 | $1327 |
| Institutional Class Shares | $96 | $300 | $520 | $1154 |

---

**Portfolio Turnover**

The Value 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 Total Annual Fund Operating Expenses or in the example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 44% of the average value of its portfolio.

**Principal Investment Strategies of the Value Fund**

The Value Fund invests primarily in common stocks of small companies with market capitalizations less than the largest companies in the Russell 2000<sup>®</sup> Value Index, and may invest a portion of its assets in micro-capitalization securities, generally those with market capitalizations of less than $500 million at the time of purchase. As of April 30, 2025, the largest market capitalization of a company in the Russell 2000<sup>®</sup> Value Index was $7.4 billion. The median market capitalization of the Fund is expected to fluctuate over time depending on Heartland Advisors' perceptions of relative valuations, future prospects, and market conditions.

The Fund utilizes Heartland Advisors' disciplined and time-tested 10 Principles of Value Investing™ framework to identify securities with the potential for appreciation and a potential margin of safety to limit downside risk. The 10 Principles of Value Investing™ are: catalyst for recognition, low price in relation to earnings, low price in relation to cash flow, low price in relation to book value, financial soundness, positive earnings dynamics, sound business strategy, capable management and insider ownership, value of the company, and positive technical analysis.

**Principal Risks of investing in the value fund**

The Value Fund is designed for investors who seek long-term capital appreciation from small company stocks. It is designed for investors who can tolerate the greater investment risk and market volatility associated with smaller companies, but want to manage these risks by investing in companies believed to be undervalued relative to their intrinsic value.

The principal risk of investing in the Value Fund is that its share price and investment return will fluctuate, and you could lose money. The following is a summary of the additional principal investment risks of the Fund:

**Management Risk.** The ability of the Fund to meet its investment objective is directly related to Heartland Advisors' investment strategies for the Fund.

**General Market Risk.** The market value of a security may move up or down, sometimes rapidly and unpredictably. These fluctuations may cause a security to be worth less than the price originally paid for it, or less than it was worth at an earlier time.

**common stock Risk.** Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change.

**Value-Style Investing Risk.** Value stocks can perform differently from the market as a whole and from other types of stocks. Value investments are subject to the risk that their intrinsic value may not be recognized by the broad market.

**SMALLER COMPANY SECURITIES RISK.** Investing in securities of small-cap and micro-cap companies generally involves a higher degree of risk than investing in securities of larger companies. The prices of securities of smaller companies are generally more volatile than those of larger companies, they generally will have less market liquidity, and they may be more likely to be adversely affected by poor economic or market conditions. These risks generally increase as the size of the company decreases. Micro-cap companies generally have less public information and can have less financial resources and management experience than larger companies, increasing the risk of business failure.

**Recent Market Events.** U.S. and international markets have experienced volatility in recent months and years due to a number of economic, political and global macro factors, including elevated inflation levels, trade tensions, tariff arrangements, and wars in Europe and in the Middle East. Uncertainties regarding interest rate levels, political events, rising government debt in the U.S. and the possibility of a national or global recession have also contributed to market volatility. Continuing market volatility may have an adverse effect on the Fund. Heartland Advisors will monitor developments and seek to manage the Fund in a manner consistent with achieving the Fund's investment objective, but there can be no assurance that it will be successful in doing so.

**Sector Risk.** Although Heartland Advisors selects stocks based on their individual merits, some economic sectors will represent a larger portion of the Fund's overall investment portfolio than other sectors. Potential negative market or economic developments affecting one of the larger sectors could have a greater impact on the Fund than on a fund with less weighting in that sector.

&nbsp;&nbsp;&nbsp;&nbsp;▪ *Financials Sector Risk*. Companies in the financials sector are subject to risks relating to regulatory
 change, decreased liquidity in credit markets and unstable interest rates.

**TAX LAW change RISK**. All statements contained in this Prospectus regarding the U.S. federal income tax consequences of an investment in the Fund are based on current law, which is subject to change at any time, potentially with retroactive effect. Legislation changes over the last several years, the expiration of currently-effective legislation, and possible future U.S. tax legislation and administrative guidance, could materially affect the tax consequences of your investment in the Fund and the Fund's investments.

**CYBERSECURITY RISK**. The Fund is susceptible to operational, information security, and related cybersecurity risks. Cyber incidents affecting the Fund or its service providers may cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund's ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.

**Operational Risk**. Operational risks include failures in systems, technology, or processes, changes in personnel or systems, inadequate controls, and human error. The Fund and Heartland Advisors seek to reduce the risk of an operational event through controls and procedures, but such measures cannot address every possible risk, including instances at third parties, and may be inadequate to address these risks.

An investment in the Fund is not a deposit of a bank, nor insured or guaranteed by the Federal Deposit Insurance Corporation ("FDIC") or any other governmental agency. It is not designed to be a complete investment program, and while you may make money, you can also lose money. The Fund's share price will fluctuate.

**Past Performance**

The following tables show historical performance of the Value Fund and provide some indication of the risks of investing in the Fund. Table I shows how the total returns before taxes for the Fund's Investor Class Shares have varied from year to year for the past 10 years. Table II shows how the Fund's average annual total returns compare to those of a broad measure of market performance, as well as the Fund's benchmark index. Past performance (before and after taxes) does not guarantee future results. Updated performance information for the Fund is available on the Fund's website at heartlandadvisors.com or by calling 1-800-432-7856.

After-tax returns are calculated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred or other tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts ("IRAs"). In addition, after-tax returns are shown only for Investor Class Shares and after-tax returns for the Institutional Class Shares will vary. The differences in before-tax returns and after-tax returns on distributions and sale of Fund shares are due to adjustments incorporated into the after-tax returns for qualified taxable dividend income and qualifying foreign tax credits.
