EXAMPLE

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 you reinvest all dividends and distributions, 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 the assumptions, your costs would be:

	One Year	Three Years	Five Years	Ten Years
Investor	$171	$530	$913	$1,987
Institutional	$125	$390	$676	$1,489

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 141% of the average value of its portfolio.

Principal Investment Strategy

Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities of large-cap companies “principally engaged” in the business of providing financial services. An issuer is “principally engaged” in the business of providing financial services if at least 50% of its assets, gross income, or net profits are committed to, or derived from, financial services activities. Financial services activities are activities primarily related to consumer and commercial banking, insurance, securities and investments, specialty finance and real estate. The Fund may also invest in companies in the information technology industries that primarily provide products and/or services to companies in the financial services group of industries. The Fund considers a large-cap company to be one that has a market capitalization of $3 billion or more, measured at the time of purchase. The Fund’s investments will consist primarily of common stocks, but may include preferred stocks, warrants and convertible bonds.

When evaluating securities to purchase, the Portfolio Managers generally look for companies that have a low price-to-earnings ratio and low price-to-book ratio relative to the financial services group of industries.

The Fund will not invest more than 5% of its total assets in the equity-related securities of any one company that derives more than 15% of its revenues from brokerage or investment management activities.

Principal Risks

As with any security, there are market and investment risks associated with your investment in the Fund. The value of your investment will fluctuate over time and it is possible to lose money. The principal risks of investing in the Fund include the following:

Market and Equity Investments Risk: The market value of a security may move up or down, and these fluctuations may cause a security to be worth more or less than the price originally paid for it. Market risk may affect a single company, an industry, a sector of the economy or the market as a whole. The value of equity securities will fluctuate due to many factors, including the past and predicted earnings of the issuer, the quality of the issuer’s management, general market conditions, forecasts for the issuer’s industry and the value of the issuer’s assets.

Temporary Defensive Positions Risk: The Fund may, from time to time, take temporary defensive positions in response to adverse market, economic, political or other conditions. To the extent the assets of the Fund are invested in temporary defensive positions, the Fund may not achieve its investment objective. For temporary defensive purposes, the Fund may invest in cash and/or short-term obligations.

Medium- and Large-Sized Companies Risk: Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in consumer tastes or innovative smaller competitors. Also, large-cap companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion. Compared to larger companies, medium-sized companies may have a shorter history of operations, and may have more limited liquidity and greater price volatility than larger, more established companies. Medium-sized companies may have more limited product lines, markets or financial resources than large companies.

Industry Concentration Risk: The Fund concentrates its investments within the financial services group of industries. Because of its narrow industry focus, the performance of the Fund is tied closely to and affected by developments in the financial services group of industries, such as the possibility of adverse government regulation. Financial services companies can be influenced by adverse effects of movements in interest rates and other factors.

Non-Diversification Risk: Because the Fund is non-diversified (meaning that compared to diversified mutual funds, the Fund may invest a greater percentage of its assets in a more limited number of issuers), the Fund’s shares may be more susceptible to adverse changes in the value of a particular security than would be the shares of a diversified mutual fund. Thus, the Fund may be more volatile because each stock in which it invests could have greater impact on the Fund’s performance.

Performance Information

The following performance information provides some indication of the risks of investing in the Fund by showing changes in its performance from year to year and how the Fund’s average annual returns for 1, 5, and 10 years compare with those of an index that reflects a broad measure of market performance, the Russell 1000® Index, as well as an additional index that reflects the market sector in which the Fund invests, the Russell 1000® Financial Services Index. For additional information on these indices, please see “Descriptions of Indices” on page 60 of the Prospectus. The Fund is the successor to the FBR Large Cap Financial Fund (the “Predecessor Large Cap Financial Fund”). The performance information provided for the periods on or prior to October 26, 2012, is historical information for the Predecessor Large Cap Financial Fund, which had the same investment objective and substantially similar investment strategy as the Fund. The Fund’s past performance (before and after taxes) is not necessarily an indication of future performance. Performance may be higher or lower in the future. Updated performance information is available on the Hennessy Funds’ website (hennessyfunds.com).

We use the Russell 1000^® Financial Services Index as an additional index because it compares the Fund’s performance with the return of an index reflecting the performance of investments similar to those of the Fund.

The 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 the 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 Investor Class shares only and after-tax returns for Institutional Class shares will vary.

The inception date of the Fund’s Institutional Class shares is June 15, 2015. Performance shown prior to the inception of Institutional Class shares reflects the performance of the Fund’s Investor Class shares and includes expenses that are not applicable to and are higher than those of Institutional Class shares.

Distributions on Fund shares are taxable and will be taxed as ordinary income or capital gains unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account, in which case such distributions may be taxable at a later date.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Fund shares through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for performing shareholder services or distribution-related services for the Fund. If made, these payments may create a conflict of interest by influencing the broker-dealer or other financial intermediary and your financial adviser to recommend the Fund over another investment. Ask your financial adviser or visit your financial intermediary’s website for more information.
