Risk/Return Summary
Investment Objectives/Goals
The Fund´s primary objective is growth of capital.

Fee Table
This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the American Growth Fund. More information about these and other discounts is available from your financial professional and in How to Reduce your Sales Charge, page 17 of the Fund´s prospectus and under Distribution of Shares, page 13 of the Fund´s Statement of Additional Information (“SAI”).

Annual Fund Operating Expenses (Expenses that you pay each year as a percentage of the value of your investment) ended July 31, 2024:

(a) Purchases of Class A and Class D shares in amounts of $1,000,000 or more which are not subject to an initial sales charge generally will be subject to a contingent deferred sales charge of 1.0% of amounts redeemed within the first year of purchase. See Class A and D Sales Charges on page 15.
(b) Contingent Deferred Sales Charge for the 1st 2 years is 5%, 3rd & 4th years - 4%, 5th yr. - 3%, 6th yr. - 2%, 7th yr. - 1%.
(c) In the first year after purchase.

(d) The Total Annual Fund Operating Expenses may not correlate to the ratio of expenses to average net assets in the Financial Highlights Table below, which do not include acquired fund fees and expenses.

This Example 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 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. Seven years after the date of purchase, Class B & C Shares automatically convert to Class A Shares. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

You would pay the following expenses if you did not redeem your shares:

The Example does not reflect sales charges (loads) on reinvested dividends and other distributions. If these sales charges (loads) were included, your costs would be higher.

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 most recent fiscal year, the Fund´s portfolio turnover rate was 4% of the average market value of its portfolio.

Principal Investment Strategy
Investment Research Corporation (the "Advisor”, “Investment Advisor”, or “IRC”) manages the Fund using a growth style of investing. We use a consistent approach to build the Fund´s investment portfolio which is made up primarily of common stocks and securities convertible into common stock. These securities are issued primarily by large companies, and to a lesser extent, small and mid-sized companies. When a company´s fundamentals are strong, we believe earnings growth will follow. The Fund may invest in securities of other investment companies, including exchange-traded funds, to obtain desired exposures.

Principal Risks of Investing in the Fund
Loss of some or all of the money you invest is a risk of investing in the Fund.
The primary risks of investing in the Fund are:
l Stock Market Risk - the value of an investment may fluctuate widely and could decline, sometimes rapidly and unpredictably.
l Operational and Cybersecurity Risk - Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting the companies and other issuers in which the Fund invests may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes. In addition, markets and market participants are increasingly reliant on information data systems. Inaccurate data, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large, which could negatively impact the value of one or more of the Fund’s investments.
l Market Risk - Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and geopolitical events, such as political or economic dysfunction within nations. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or other public health crises. Policy changes by the U.S. government and/or the Fed and political events within the United States and other countries may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. A downgrade of the ratings of U.S. government debt obligations, or concerns about the U.S. government’s credit quality in general, could have a substantial negative effect on the U.S. and global economies.

Downgrades affecting other countries also could have similar impacts. In addition, high public debt in the United States and other countries creates ongoing systemic and market risks and policymaking uncertainty.
l Early Close/Trading Halt Risk. An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may prevent the Fund from buying or selling certain securities or financial instruments.
l Industry and Security Risk - the risk that the value of securities in a particular industry or the value of an individual stock or bond will decline because of changing expectations for the performance of that industry or for the individual company issuing the stock or bond.
l Management Risk - risks that the Advisor´s assessment of a company´s growth prospects may not be accurate.
l Interest Rate Risk – as rates rise, the price of a fixed rate bond generally will fall.
l Credit Risk – a bond’s issuer may be unable to make timely payments of interest and capital.
l Foreign Investment Risk – adverse effects from political instability, currency exchange rates, economic conditions or regulatory and accounting standards outside the United States.
l Liquidity Risk - a given security or asset may not be readily marketable. Illiquid investments may be difficult or impossible to sell or purchase at an advantageous time or price or in sufficient amounts to achieve the Fund's desired level of exposure.
l Small Cap Risk - small cap stocks tend to have a high exposure to market fluctuations and failure.
l Mid Cap Risk - mid cap stocks tend to have a greater exposure to market fluctuations and failure.
l Equity Risk – stock and equity values fluctuate in response to a company’s financial condition and other factors, including general market conditions, and could decline. The level of volatility could be high..
l Repurchase Agreement Risk – a seller may default or a security declines in value.
l Depositary Receipts Risk – generally these are subject to the same risks as Foreign Investment Risks.
l Convertible Securities – convertible securities have the risk of loss of principal at maturity.
l Large Cap Company Risk – slower response to competitors and technology and consumer tastes, and slower growth rates during periods of economic expansion.
l Investments in Other Investment Companies Risk - the Fund’s investments in other investment companies will be subject to the risks of the other investment companies’ portfolio securities and the Fund will bear indirectly the fees and expenses of the other investment companies in which it invests.
l Exchange-Traded Funds (“ETFs”) Risk - The Fund is subject to the risks associated with the securities or other investments in which the ETFs invest. The Fund’s shareholders will indirectly bear fees and expenses paid by the ETFs in which it invests, in addition to the Fund’s direct fees and expenses. An index-based ETF’s performance may not match that of the index it seeks to track. An actively managed ETF’s performance will reflect its advisor’s ability to make investment decisions that are suited to achieving the ETF’s investment objective.
l Technology Securities Risk - Certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Investments in technology companies generally can be volatile and fluctuate widely, sometimes rapidly and unpredictably.

Risk/Return Bar Chart and Table
The bar chart and table are intended to provide you with an indication of the risks of investing in the Fund by showing changes in performance from year to year and by showing how the Fund´s average annual returns for Class D shares for 1, 5 and 10 years compare to those of the Standard and Poor’s 500 Index total return. Past performance, before and after taxes, is not predictive of future performance. Sales load and account fees are not reflected in the bar chart. If the sales load and account fees were included, the returns would be less than those that are shown. Updated performance information for the Fund is available at the Fund´s web site (www.americangrowthfund.com) or toll-free telephone number (800) 525-2406.

Highest quarterly return: 21.79% for the quarter ended June 2020. Lowest quarterly return: -18.25% for the quarter ended March 2020. Year to date performance for the period ended 9/30/2024 was 20.34%.

* Assumes redemption at end of time period.
** After seven years Class B & C Shares convert to Class A Shares. The ten year return for Class B & C shares reflects the first seven year returns for Class B & C shares and the remaining 3 years as Class A.
After-tax returns are calculated using the historical highest 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 arrangements, such as 401(k) plans or individual retirement accounts;
After-tax returns are shown for only Class D and after-tax returns for other Classes will vary.

The Investment Advisor

Purchase and Sale of Fund Shares
When purchasing Fund shares there is no minimum initial or subsequent amount required. You can purchase and sell your shares on any business day through your financial advisor, by mail by writing to: American Growth Fund, 1636 N. Logan Street, Denver, CO 80203, by wire if the purchase or sale is over $1,000, or by calling 800-525-2406 if the purchase or sale is $5,000 or less.

Tax Consequences
Distributions from the Fund´s long-term capital gains are taxable as capital gains, while distributions from short-term capital gains and net investment income are generally taxable as ordinary income.

Payments to Broker-Dealers and Other Financial Intermediaries
If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary´s Web site for more information.

Investment Objectives, Principal Investment Strategies, Related Risks, and Disclosure of Portfolio Holdings
What is the Fund´s investment objective?
The Fund´s investment objective, which is fundamental and cannot be changed without shareholder approval, is growth of capital. Income only becomes a Fund objective when it is in a temporary, defensive position.

How does the Fund implement its investment objective?
In attempting to achieve its investment objective, the Fund will typically invest at least 80% of its assets in common stocks and securities convertible into common stocks traded on national securities exchanges or over-the-counter markets.
We perform our own extensive internal research to determine whether companies meet our growth criteria. If the Investment Advisor deems it necessary, we may meet company management teams as well as other key staff face-to-face and/or may tour corporate facilities and manufacturing plants to help us get a more complete picture of a company before we invest.
We limit the amount of the Fund´s assets invested in any one industry and in any individual security. At the time of purchase, we do not invest more than 5% of the Fund´s total assets in any one issuer nor do we invest more than 25% in any one industry. We also follow a rigorous selection process designed to identify undervalued securities with significant growth potential before choosing securities for the portfolio.
Although the Fund will normally invest in large capitalization companies, the Fund may invest in companies of all sizes. Investment Research Corporation, the Fund´s investment Advisor (the “Advisor”, “Investment Advisor”, or “IRC”), generally will choose common stocks (or convertible securities) that it believes have a potential for capital appreciation because of existing or anticipated economic conditions or because the securities are considered undervalued or out of favor with investors or are expected to increase in price over the short-term. Convertible debt securities will be rated at least A by Moody´s Investor Service or Standard and Poor’s Ratings Services, or, if unrated, will be comparable quality in the opinion of the advisor.
We maintain a long-term investment approach and focus on stocks we believe can appreciate over an extended time frame regardless of interim market fluctuations. Using the following disciplined approach, we look for companies having some or all of these characteristics:

l Large capitalization companies, although on occasion the Fund may invest in small and mid-cap companies, if the Advisor believes it is in the best interests of the Fund. Large cap companies are generally companies with market capitalization exceeding $5 billion at the date of acquisition;
l Growth that is faster than the market as a whole and sustainable over the long term;
l Strong management team;
l Leading market positions and growing brand identities;
l Financial, marketing, strategy and operating strength.
Although a non-principal strategy, the Fund may invest in foreign securities in the form of American Depositary Receipts.
The Fund may invest in securities of other investment companies, including exchange-traded funds.
The Fund emphasizes investments in common stocks with the potential for capital appreciation. These stocks generally pay regular dividends, although the Fund also may invest in non-dividend-paying companies if, in the opinion of an Advisor, they offer better prospects for capital appreciation.
When selecting investments for the portfolio, a company’s environmental, social, and governance policies are not factors.

When the Advisor believes the securities the Fund holds may decline in value, the Fund may sell them and, if the Advisor believes market conditions warrant, the Fund may assume a defensive position. While in a defensive position, the Fund may invest all or part of its assets in corporate bonds, debentures (both short and long term) or preferred stocks rated A or above by Moody´s Investors Service, Inc., Standard and Poor’s or Fitch Ratings (or, if unrated, of comparable quality in the opinion of the Advisor), United States Government securities, repurchase agreements meeting approved credit worthiness standards (e.g., whereby the underlying security is issued by the United States Government or any agency thereof), or retain funds in cash or cash equivalents. There is no maximum limit on the amount of fixed income securities in which the Fund may invest for temporary defensive purposes. If the Fund takes a temporary defensive position in attempting to respond to adverse market, economic, political or other conditions, it may not achieve its investment objective. The Fund´s performance could be lower during periods when it retains or invests its assets in these more defensive holdings.
A repurchase agreement is a contract under which the seller of a security agrees to buy it back at an agreed upon price and time in the future.
The Fund will enter into repurchase transactions only with parties who meet creditworthiness standards approved by the Fund´s board of directors.
The Fund may invest in foreign securities in the form of American Depositary Receipts (ADRs) which represents ownership in the shares of a non-U.S. company that trades in U.S. financial markets. We typically invest only a small portion of the Fund´s portfolio in foreign corporations through ADRs. We do not invest directly in foreign securities. When we do purchase ADRs, they are generally denominated in U.S. dollars and traded on a U.S. exchange.
We seek to limit exposure to illiquid securities.

Risks
Investing in any mutual fund involves risk, including the risk that you may receive little or no return on your investment, and the risk that you may lose part or all of the money you invest.
l Stock Market risk is the risk that all or a majority of the securities in a certain market - such as the stock or bond market - will decline in value because of factors such as economic conditions, future expectations or investor confidence, sometimes rapidly and unpredictably.
l Operational and cybersecurity risk - Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting the companies and other issuers in which the Fund invests may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes. In addition, markets and market participants are increasingly reliant on information data systems. Inaccurate data, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large, which could negatively impact the value of one or more of the Fund’s investments.
l Market Risk - Economies and financial markets throughout the world are becoming increasingly

interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and geopolitical events, such as political or economic dysfunction within nations. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics or other public health crises. Policy changes by the U.S. government and/or the Fed and political events within the United States and other countries may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. A downgrade of the ratings of U.S. government debt obligations, or concerns about the U.S. government’s credit quality in general, could have a substantial negative effect on the U.S. and global economies. Downgrades affecting other countries also could have similar impacts. In addition, high public debt in the United States and other countries creates ongoing systemic and market risks and policymaking uncertainty.
l Early Close/Trading Halt Risk is the risk that an exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may prevent the Fund from buying or selling certain securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and may incur substantial trading losses.
l Industry and security risk is the risk that the value of securities in a particular industry or the value of an individual stock or bond generally will decline because of changing expectations for the performance of that industry or for the individual company issuing the stock or bond.
l Management risk is the risk that the Advisor´s assessment of a company´s ability to increase earnings faster than the rest of the market is not correct, the securities in the portfolio may not increase in value, and could decrease in value.
l Interest rate risk is the risk that changes in interest rates may affect the yield, liquidity and value of investments in income producing or debt securities. As rates rise, the price of a fixed rate bond will fall.
l Credit risk is the possibility that a bond´s issuer (or an entity that insures a bond) will be unable to make timely payments of interest and principal.
l Foreign investment risk is the risk that foreign securities may be adversely affected by political instability, changes in currency exchange rates, foreign economic conditions or inadequate regulatory and accounting standards outside the United States.
l Liquidity risk - a given security or asset may not be readily marketable. Illiquid investments may be difficult or impossible to sell or purchase at an advantageous time or price or in sufficient amounts to achieve the Fund's desired level of exposure.
l Small Cap stocks tend to have a high risk exposure to market fluctuations and failure.
l Mid Cap stocks also tend to have a greater risk exposure to market fluctuations and failure but normally not as much so as the Small Cap stocks.
l Equity Risk. In general, stocks and other equity security values fluctuate, and sometimes widely fluctuate, in response to changes in a company’s financial condition as well as general market, economic and political conditions and other factors. The level of volatility could be high.
l Repurchase Agreements Risk. The Fund may enter into repurchase agreements under which it purchases a security that a seller has agreed to repurchase from the Fund at a later date at the same price plus interest. If a seller defaults and the security declines in value, the Fund might incur a loss. If the seller declares bankruptcy, the Portfolio Fund may not be able to sell the security at the desired time.
l Depositary Receipts Risk. Investments in depositary receipts (including American Depositary Receipts, European Depositary Receipts and Global Depositary Receipts) are generally subject to the same risks of investing in the foreign securities that they evidence or into which they may be converted. In addition, issuers underlying unsponsored depositary receipts may not provide as much information as U.S. issuers and issuers underlying sponsored depositary receipts. Unsponsored depositary receipts also may not carry the same voting privileges as sponsored depositary receipts.
l Convertible Securities have the risk of loss of principal at maturity, however, this loss is limited to the

value of the bond floor.
l Large Cap Company Risk is the risk that larger more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Many larger companies also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.
l Investments in Other Investment Companies is the risk that the Fund’s investments in other investment companies will be subject to the risks of the purchased investment company’s portfolio securities. The Fund’s shareholders must bear not only their proportionate share of the Fund’s fees and expenses, but they also must bear indirectly the fees and expenses of the other investment company. In addition, the Fund’s net asset value is subject to fluctuations in the net asset values of the other investment companies in which it invests. The ability of the Fund to meet its investment objective will depend, to a significant degree, on the ability of the other investment companies to meet their objectives.
l Exchange-Traded Funds (“ETFs”). ETFs are investment companies whose shares are listed on a securities exchange and trade like a stock throughout the day. Investments in ETFs are subject to a variety of risks, including risks associated with the underlying securities that the ETF holds. The Fund’s net asset value will be subject to fluctuations in the market values of the ETFs in which it invests. Also, ETFs that track particular indices typically will be unable to match the performance of the index exactly due to the ETF’s operating expenses and transaction costs, among other things. Similar to investments in other investment companies, the Fund’s shareholders must bear not only their proportionate share of the Fund’s fees and expenses, but they also must bear indirectly the fees and expenses of the ETF. In addition, the ability of the Fund to meet its investment objective will directly depend on the ability of the ETFs to meet their investment objectives. The extent to which the investment performance and risks associated with the Fund correlate to those of a particular ETF will depend upon the extent to which the Fund’s assets are allocated from time to time for investment in the ETF, which will vary.
l Technology Securities Risk is the risk that certain technology related companies may face special risks that their products or services may not prove to be commercially successful. Technology related companies are also strongly affected by worldwide scientific or technological developments. As a result, their products may rapidly become obsolete. Such companies are also often subject to governmental regulation and may, therefore, be adversely affected by governmental policies. Investments in technology companies generally can be volatile and fluctuate widely, sometimes rapidly and unpredictably.
Please see the Statement of Additional Information for further discussion of risks.

Management, Organization, and Capital Structure
The Investment Advisor
Investment Research Corporation ("IRC") has been the Advisor for the Fund since American Growth Fund, Inc.’s inception in 1958. IRC is located at 1636 N. Logan Street, Denver, CO 80203. The Fund offers four classes of shares; Class A, Class B, Class C and Class D. All classes of shares of the Fund represent an identical interest in the investment portfolio. The Fund has an agreement to pay IRC an annual fee for its services based on a percentage of the Fund´s Class A, Class B, Class C, and Class D average net assets. Under the investment advisory contract with IRC, IRC receives annual compensation

for investment advice on these classes, computed and paid monthly, equal to 1% of the first $30 million of the Fund´s Class A, Class B, Class C, and Class D average annual net assets and 0.75% of such assets in excess of $30 million. For the fiscal year ended July 31, 2024, this fee amounted to 1.00% of the average net assets on each of the Fund´s four classes.
For the year ended July 31, 2024, under an agreement with IRC, the Fund paid $167,189 for the costs and expenses related to employees of IRC who provided administrative, clerical and accounting services to the Fund. In addition, the Fund paid $132,484 to an affiliated company of IRC for the rental of office space.
The Fund, and therefore, the Fund shareholders, pays the Fund´s operating expenses.
On September 23, 2010 an Investment Advisory Committee was formed with the purpose of offering investment advice to a senior portfolio manager of the Fund. The current members of the Investment Advisory Committee are Timothy Taggart, Robert Fleck and Matthew Taggart.
IRC may compensate third party intermediaries, including investment advisors and broker-dealers, from IRC’s own revenue for assisting IRC in establishing relationships with other third party intermediaries such as investment advisors and/or sub-manager programs and disseminating information concerning IRC to financial professionals.
The Fund and the Advisor have a Code of Ethics designed to ensure that the interests of Fund shareholders come before the interests of the people who manage the Fund. Among other provisions, the Code of Ethics prohibits portfolio managers and other investment personnel from buying securities in an initial public offering without prior written consent or from profiting from the purchase and sale of the same security within one calendar day. In addition, the Code of Ethics requires portfolio managers and other employees with access to information about the purchase or sale of securities by the Fund to obtain approval before executing personal trades in these specific securities. A copy of the Fund´s Code of Ethics can be obtained for free online at www.americangrowthfund.com or by calling us at 1-800-525-2406.
A discussion regarding the basis for the board of directors approving the advisory contract of the fund is available in the fund’s report on Form N-CSR for the fiscal half-year period ended January 31, 2024, which can be obtained online at www.sec.gov or by calling 800-525-2406.

Chief Compliance Officer
Michael L. Gaughan is the Fund´s Chief Compliance Officer (CCO). The Fund´s CCO seeks to ensure that policies and guidelines, set forth by the CCO and the Board of Directors, that guard against violations of federal securities laws, are adhered to. These policies and procedures are annually reviewed by the CCO and the Board of Directors to determine their adequacy and their effectiveness.

Shareholder Information
Pricing of Fund Shares
The price you pay for shares will depend on when we receive your purchase order. If we or an authorized agent receive your order before the close of trading on the New York Stock Exchange on a business day, you will pay that day´s closing share price, which is based on the Fund´s net asset value (“NAV”). If we receive your order after the close of trading, you will pay the next business day´s price. A business day is any day that the New York Stock Exchange is open for business. Currently the Exchange is closed when the following holidays are observed: New Years Day, Martin Luther King, Jr.´s Birthday, Presidents Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. We reserve the right to reject any purchase order.
We determine the Fund´s NAV per share at the close of trading of the New York Stock Exchange each business day that the Exchange is open. We calculate this value by adding the market value of all the securities and assets in the Fund´s portfolio, deducting all liabilities, and dividing the resulting number by the shares outstanding. The result is the NAV per share. We price securities and other assets for which market quotations are available at their market value. We price debt securities on the basis of valuations provided to us by an independent pricing service that uses methods approved by our board of directors. Any debt securities that have a maturity of less than 60 days are priced at amortized cost. We price all other securities at their fair value if no bid and asked prices are quoted for such day or information as to New York or other approved exchange transactions is not readily available. The Fund’s board of directors has designated the Advisor as the Fund’s valuation designee. As the valuation designee, and subject to the board’s oversight, the Advisor is responsible for determining in good faith the fair value of Fund investments for which market quotations are not readily available or are believed by the Adviser to be unreliable. In these circumstances, the Fund may use a fair value estimate made according to methods the Advisor has approved in the good-faith belief that the resulting valuation will reflect the fair value of the security. The effect of fair value pricing as described above is that securities may not be priced on the basis of quotations from the primary market in which they are traded, but rather may be priced by another method that the Advisor believes will reflect fair value. As such, fair value pricing is based on subjective judgments and it is possible that fair value may differ materially from the value realized on a sale. This policy is intended to assure that the Fund’s net asset value fairly reflects security values as of the time of pricing. Also, fair valuation of the Fund’s securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of the Fund’s net asset value by those traders.

Special Services Available when Purchasing Fund Shares

Direct Deposit - With Direct Deposit you can make additional investments through payroll deductions or recurring government or private payments, such as direct transfers from your bank account.
Dividend Reinvestment Plan - Through our Dividend Reinvestment Plan, you can have your distributions reinvested in your account. The shares that you purchase through the Dividend Reinvestment Plan are not subject to a front-end sales charge or to a contingent deferred sales charge. Under most circumstances, you may reinvest dividends only into like classes of shares.
Systematic Withdrawal Plan - Through our Systematic Withdrawal Plan you can arrange a regular monthly or quarterly payment from your account made to you or someone you designate. You may also have your withdrawals deposited directly to your bank account through our MoneyLine Direct Deposit Services.

Retirement Plans
In addition to being an appropriate investment for your Individual Retirement Account (IRA) and Roth IRA, shares in the Fund may be suitable for group retirement plans. You may establish your IRA account even if you are already a participant in an employer-sponsored retirement plan. For more information on how shares in the Fund can play an important role in your retirement planning or for details about group plans, please consult your financial Advisor, or call 1-800-525-2406.

How to Redeem Shares
Through your financial Advisor
Your financial Advisor can handle all the details of redeeming shares. Your Advisor may charge a separate fee for this service.
By mail
You can redeem your shares (sell them back to the Fund) by mail by writing to: American Growth Fund, Inc., 1636 N. Logan Street, Denver, CO, 80203. All owners of the account must sign the request, and for redemptions of $5,000 or more, you must include a signature guarantee for each owner. Signature guarantees are also required when redemption proceeds are going to an address other than the address of record on an account. A signature guarantee is a certification by a bank, brokerage firm or other financial institution that a customer´s signature is valid; signature guarantees can be provided by members of the STAMP program (a program made up of members who are authorized to issue signature guarantees).
By wire
You can redeem $1,000 or more of your shares and have the proceeds deposited directly to your bank account the next business day after we receive your request. Bank information must be on file before you request a wire redemption.
By phone
You can redeem shares by phone. All shareholders must be on the call, redemption must be $5,000 or less per day, per telephone call and the proceeds must be sent to the address of record and made payable to all listed shareholders. Please remember that redemptions by check are restricted after an address change, unless a signature guaranteed letter requesting the redemption is submitted.

If you hold your shares in certificates, you must submit the certificates with your request to sell the shares. We recommend that you send your certificates by certified mail.
When you send us a properly completed request to redeem or exchange shares, you will receive the net asset value as determined on the business day we receive your request if we receive it before the close of the NYSE. We will deduct any applicable contingent deferred sales charges. We will send you a check, normally the next business day, but no later than seven days after we receive your request to sell your shares. If you recently purchased your shares by check, we will wait until your check has cleared, which can take up to 15 days, before we send your redemption proceeds.
If you are required to pay a contingent deferred sales charge when you redeem shares, the amount subject to the fee will be based on the shares´ net asset value when you purchased them or their net

asset value when you redeem them, whichever is less. This arrangement assures that you will not pay a contingent deferred sales charge on any increase in the value of your shares. The redemption price for purposes of this formula will be the NAV of the shares you are actually redeeming.
Conversion of Class B and C Shares to Class A Shares. After approximately seven years (the Conversion Period), Class B and C shares will be converted automatically into Class A shares of the Fund. Class A shares are subject to an ongoing service fee of 0.25% of average net assets and are subject to a distribution fee of 0.05% of average net assets. Automatic conversion of Class B and C shares into Class A shares will occur at least once each month (on the Conversion Date) on the basis of the relative net asset values of the shares of the two classes on the Conversion Date, without the imposition of any sales load, fee or other charge. Conversion of Class B and C shares to Class A shares will not be deemed a purchase or sale of the shares for Federal income tax purposes.
In addition, shares purchased through reinvestment of dividends and distributions on Class B and C shares also will convert automatically to Class A shares. The Conversion Date for dividend reinvestment shares will be calculated taking into account the length of time the shares underlying such reinvestment shares were outstanding. If at a Conversion Date the conversion of Class B or C shares to Class A shares of the Fund in a single account will result in less than $50 worth of Class B or C shares being left in the account, all of the Class B and C shares of the Fund held in the account on Conversion Date will be converted to Class A shares of the Fund.
Share certificates for Class B and C shares of the Fund to be converted must be delivered to the Transfer Agent at least one week prior to the Conversion Date applicable to those shares. In the event such certificates are not received by the Transfer Agent at least one week prior to the Conversion Date, the related Class B and C shares will convert to Class A shares on the next scheduled Conversion Date after such certificates are delivered.
Generally, all redemptions will be for cash. The Fund expects to satisfy all redemption requests, assuming they are in good order, under both regular market conditions as well as in stressed market conditions, by selling portfolio assets or by using holdings of cash or cash equivalents. All redemptions will typically be processed and mailed within two business days.

Account Minimum
If you redeem shares and your account balance falls below $1,000 and stays there for a period of 12 months or longer, the Fund may redeem your account 30 days after written notice to you.

Dividends and Distributions
The Fund´s policy is to declare and pay income dividends and capital gains distributions to its shareholders in December of each calendar year unless the Board of Directors of the Fund determines that it is to the shareholders’ benefit to make distributions on a different basis.
Unless the shareholder on his or her application or in writing, previously requests dividend and distribution payments in cash, income dividends and capital gains distributions will be reinvested in Fund shares of the same class, at their relative net asset values as of the business day next following the distribution record date. If no instructions are given on the application form, all income dividends and capital gains distributions will be reinvested.
The Fund intends to make distributions that may be taxed as ordinary income and capital gains (capital gains may be taxable at different rates depending on the length of the time the Fund holds its assets).
We will send you a statement each year by January 31st detailing the amount and nature of all dividends and capital gains that you were paid for the prior year.
Distributions by the Fund, whether received in cash or reinvested in additional shares of the Fund, may be subject to federal income tax. Any capital gains may be taxable at different rates depending on the length of time the Fund held the assets. In addition, you may be subject to state and local taxes on distributions. An exchange of the Fund´s shares for shares of another fund will be treated as a sale of the Fund´s shares and any gain on the transaction may be subject to tax.

Frequent Purchases and Redemptions of Fund Shares
The Fund is not designed to serve as vehicles for frequent trading in response to short-term fluctuations in the securities markets. Accordingly, purchases, including those that are part of exchange activity, that American Growth Fund, Inc. has determined could involve actual or potential harm to the Fund may be rejected. Frequent trading of a mutual fund´s shares may lead to increased costs to that fund and less

efficient management of the fund´s portfolio, resulting in dilution of the value of the shares held by long-term shareholders.
The Fund´s Board of Directors has not adopted policies or procedures with respect to frequent purchases and redemptions by Fund shareholders. Due to the size of the Fund, the Board feels that the Fund´s best interests are better served by allowing the Management of the Fund to monitor such trading activity. If at any time the Management of the Fund feels that a trade or an account is, or could, adversely affect the Fund´s performance through frequent purchasing and redeeming of Fund shares significantly increasing the costs of processing share purchase and/or redemption transactions, management reserves the right to reject the trade, suspend trading of the account(s) for a specified period of time, or both. Rejection of a trade and/or suspension(s) of trading activity will cause a letter to be promptly issued to the party(ies) involved.
The Fund has no agreement with any person(s) or corporate entity that would allow for frequent purchases and redemptions of Fund shares.

Distribution Arrangements
Sales Charges
You can choose from a number of share classes for the Fund. Because each share class has a different combination of sales charges, fees and other features, you should consult your financial Advisor to determine which class best suits your investment goals and time frame. You may also consult the Fund´s Statement of Additional Information for more details.
Class A
Class A shares have an up-front sales charge of up to 5.75% that you pay when you buy shares.
The offering price for Class A shares includes the front-end sales charge.
If you invest $50,000 or more, your front-end sales charge will be reduced.
You may qualify for other reduced sales charges, as described in How to Reduce Your Sales Charge, and under certain circumstances the sales charge may be waived.
Class A shares are also subject to an annual 12b-1 fee no greater than 0.30% of average net assets, which is lower than the 12b-1 fee for Class B and Class C shares.
Class A shares generally are not subject to a contingent deferred sales charge unless purchased in amounts of $1,000,000 or more at net asset value without a sales charge and redeemed within one year of purchase.
Additionally, IRC reserves the right to waive the front-end sales charge on share purchases by IRC employees and members of the Board of Directors of The American Growth Fund.
Class B
Class B shares have no up-front sales charge, so the full amount of your purchase is invested in the Fund.
However, you will pay a contingent deferred sales charge if you redeem your shares within seven years after you buy them.
If you redeem Class B shares during the first two years after you buy them, the shares will be subject to a contingent deferred sales charge of 5%. The contingent deferred sales charge is 4% during the third and fourth years, 3% during the fifth year, 2% during the sixth year, and 1% during the seventh year.
Under certain circumstances the contingent deferred sales charge may be waived.
For approximately seven years after you buy your Class B shares, they are subject to annual 12b-1 fees no greater than 1% of average daily net assets, of which 0.25% are service fees paid to the Distributor, dealers or others for providing services and maintaining accounts.
Because of the higher 12b-1 fees, Class B shares have higher expenses and any dividends paid on these shares are lower than dividends on Class A shares.
Approximately seven years after you buy them, Class B shares automatically convert into Class A shares with a 12b-1 fee of no more than 0.30%. Conversions may occur as late as three months after the eighth anniversary of purchase, during which time the Class B Shares higher 12b-1 fees apply.
Class C
Class C shares have no up-front sales charge, so the full amount of your purchase is invested in the Fund. However, you will pay a contingent deferred sales charge if you redeem your shares within 12 months after you buy them.
Under certain circumstances the contingent deferred sales charge may be waived.
Class C shares are subject to an annual 12b-1 fee which may not be greater than 1% of average daily net

assets, of which 0.25% is service fees and 0.75% is distribution fees paid to the distributor, dealers or others for providing personal services and maintaining shareholder accounts.
Because of the higher 12b-1 fees, Class C shares have higher expenses and pay lower dividends than Class A shares.
Conversion of Class B and C Shares to Class A Shares. After approximately seven years (the Conversion Period), Class B and C shares will be converted automatically into Class A shares of the Fund. Class A shares are subject to an ongoing service fee of 0.25% of average net assets and are subject to a distribution fee of 0.05% of average net assets. Automatic conversion of Class B and C shares into Class A shares will occur at least once each month (on the Conversion Date) on the basis of the relative net asset values of the shares of the two classes on the Conversion Date, without the imposition of any sales load, fee or other charge. Conversion of Class B and C shares to Class A shares will not be deemed a purchase or sale of the shares for Federal income tax purposes.
In addition, shares purchased through reinvestment of dividends and distributions on Class B and C shares also will convert automatically to Class A shares. The Conversion Date for dividend reinvestment shares will be calculated taking into account the length of time the shares underlying such reinvestment shares were outstanding. If at a Conversion Date the conversion of Class B or C shares to Class A shares of the Fund in a single account will result in less than $50 worth of Class B or C shares being left in the account, all of the Class B and C shares of the Fund held in the account on Conversion Date will be converted to Class A shares of the Fund.
Share certificates for Class B and C shares of the Fund to be converted must be delivered to the Transfer Agent at least one week prior to the Conversion Date applicable to those shares. In the event such certificates are not received by the Transfer Agent at least one week prior to the Conversion Date, the related Class B and C shares will convert to Class A shares on the next scheduled Conversion Date after such certificates are delivered.

Class D
Class D shares are offered to investors who owned Class D shares as of March 1, 1996. They are also available to the Fund´s Advisor, IRC, and the distributors, directors, certain institutional investors, corporations and accounts managed by specific types of fiduciaries. Additionally, IRC reserves the right to waive the front-end sales charge on purchases by IRC employees.
Class D shares have an up-front sales charge of 5.75% that you pay when you buy the shares. The offering price for Class D shares includes the front-end sales charge.
If you invest $50,000 or more, your front-end sales charge will be reduced.
You may qualify for other reduced sales charges, as described in How to Reduce Your Sales Charge, and under certain circumstances the sales charge may be waived.
Class D shares which are sold in amounts of $1,000,000 or more at net asset value and if redeemed within one year of purchase may be subject to a 1.0% contingent deferred sales charge.
The Fund´s directors have adopted separate 12b-1 plans for Class A, B, and C that allow each class to pay distribution fees for the sales and distributions of its shares. Because these fees are paid out of each Class´s assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

Class A and D Sales Charges

* As shown above, there is no front-end sales charge when you purchase $1 million or more of Class A or Class D shares. However, if your financial advisor is paid a commission on your purchase, you may have to pay a limited contingent deferred sales charge of 1% if you redeem these shares within the first year.

IRC will make payments to dealers in the amount of 0.25 of 1% per year of the average daily net asset value of outstanding Class D shares acquired after April 1, 1994 through such dealers (including shares acquired through reinvestment of dividends and distributions on such shares). These payments are made by IRC and not by the Class D shareholders of the Fund.
The Fund makes available free of charge on or though the Fund´s web site at www.americangrowthfund.com the information describing sales loads including deferred sales loads and a table of front-end sales loads and each break point in the sales load as a percentage of both the offering price and the net amount invested. The website includes a discussion on how to reduce your sales charge by using letter of intent, rights of accumulation plans, dividend reinvestment plans, withdrawal plans, exchange privileges, and waivers for particular classes of investors. This includes methods used to value accounts in order to determine whether a shareholder has met sales load breakpoints as well as and any other information that the shareholder might need to provide in order to obtain the break points.
The web site may also explain how to purchase shares including any special purchase plans or methods that may not be described in the prospectus or elsewhere in the SAI if applicable.

Intermediary-Defined Sales Charge Waiver Policies
The availability of certain initial or deferred sales charge waivers and discounts may depend on the particular financial intermediary or type of account through which you purchase or hold Fund shares.
Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or contingent deferred (back-end) sales load (“CDSC”) waivers, which are discussed below. In all instances, it is the purchaser’s responsibility to notify the fund or the purchaser’s financial intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers or discounts. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase fund shares directly from the fund or through another intermediary to receive these waivers or discounts.
Effective March 1, 2019, shareholders purchasing fund shares will be eligible only for the following load waivers (front-end sales charge waivers and contingent deferred, or back-end, sales charge waivers) and discounts, which may differ from those disclosed elsewhere in this fund’s prospectus or SAI.
Front-end sales load waivers on Class A shares available:
l Shares purchased in an investment advisory program.
l Shares purchased through reinvestment of capital gains distributions and dividend reinvestment when purchasing shares of the same fund (but not any other fund within the fund family).
l Employees and registered representatives of Broker Dealers or their affiliates and their immediate family members.
l Shares purchased from the proceeds of redemptions within the same fund family, provided (1) the repurchase occurs within 90 days following the redemption, (2) the redemption and purchase occur in the same account, and (3) redeemed shares were subject to a front-end or deferred sales load (known as Rights of Reinstatement).
l A shareholder in the Fund’s Class C shares will have their shares converted at net asset value to Class A shares (or the appropriate share class) of the Fund if the shares are no longer subject to a CDSC and the conversion is in line with the policies and procedures of the Broker Dealer.
CDSC Waivers on Classes A, B and C shares available:
l Death or disability of the shareholder.
l Shares sold as part of a systematic withdrawal plan as described in the fund’s prospectus.
l Return of excess contributions from an IRA Account.

l Shares sold as part of a required minimum distribution for IRA and retirement accounts due to the shareholder reaching age 70½ as described in the fund’s prospectus.
l Shares sold to pay Broker Dealer fees but only if the transaction is initiated by the Broker Dealer.
l Shares acquired through a right of reinstatement.
Front-end load discounts available: breakpoints, and/or rights of accumulation
l Breakpoints as described in this prospectus.
l Rights of accumulation which entitle shareholders to breakpoint discounts will be automatically calculated based on the aggregated holding of fund family assets held by accounts within the purchaser’s household. Eligible fund family assets not held at the Broker Dealer may be included in the rights of accumulation calculation only if the shareholder notifies his or her financial Advisor about such assets.

How to reduce your sales charge

You can also get additional information from your financial advisor. You or your financial Advisor must notify us at the time you purchase shares if you are eligible for any of these programs.

Financial Highlights
The financial highlight table is intended to help you understand the Fund´s financial performance for the

past 5 years. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information for the period ended July 31, 2023 and July 31, 2024 has been audited by Sanville & Company, the Fund’s current independent registered public accounting firm, whose report, along with the Fund´s financial statements, is included in the annual report, which is available upon request by contacting the Fund at 800-525-2406 or on the Fund´s web site, www.americangrowthfund.com. This information and the financial statements for each of the years ended July 31, 2020 through July 31, 2022 were audited by Tait Weller, the Fund’s former independent registered public accounting firm.

Proxy Voting
A discussion on Proxy Voting can be found on page 10 of the Fund´s Statement of Additional Information. The Statement of Additional Information, as well as how the Fund issued votes for the year ended June 30, 2024, can be obtained by calling 800-525-2406 or by visiting the Fund´s web site at www.americangrowthfund.com.

Escheatment
Certain states, including the state of Texas, have laws that allow shareholders to designate a representative to receive abandoned or unclaimed property (“escheatment”) notifications by completing and submitting a designation form that generally can be found on the official state website. If a shareholder resides in an applicable state, and elects to designate a representative to receive escheatment notifications, escheatment notices generally will be delivered as required by such state laws, including, as applicable, to both the shareholder and the designated representative. A completed designation form may be mailed to the Fund (if Shares are held directly with the Fund) or to the shareholder’s financial intermediary (if Shares are not held directly with the Fund). Shareholders should refer to relevant state law for the shareholder’s specific rights and responsibilities under his or her state’s escheatment law(s), which can generally be found on a state’s official website.
