Non-Transparent Exchange-Traded Fund (“ETF”) Structure Risk.    Unlike most actively managed ETFs the Fund does not provide daily disclosure of its portfolio holding. Instead, the Fund provides a verified intraday indicative value (“VIIV”), calculated and disseminated every second throughout the trading day. The VIIV is intended to provide investors and other market participants with a highly correlated per share value of the underlying portfolio that can be compared to the current market price. There is, however, a risk that shares of the Fund may trade at a wider bid/ask spread than ETFs that publish their portfolios on a daily basis, especially during periods of market disruption or volatility, and therefore, may cost investors more to trade. Because the Fund trades on the basis of the VIIV, it may trade at a wider bid/ask spread than traditional ETFs that publish their portfolios on a daily basis. Accordingly, the Adviser or its designee will monitor on an on-going basis how shares of the Fund trade, including the level of any market price premium or discount to NAV and the bid/ask spreads on market transactions. Should there be extended periods of unusually high bid/ask spreads, the Board will consider the continuing viability of the Fund, whether shareholders are being harmed, and what, if any, action would be appropriate to among other things, narrow the premium/discount or spread, as applicable. Potential actions may include, but are not limited to, changing lead market makers, listing the Fund on a different exchange, changing the size of Creations Units, changing the Fund’s investment objective or strategy, and liquidating the Fund. There is also a risk that the market price may vary significantly from the NAV and, thus, the underlying value of the Fund significantly from the underlying NAV of the Fund. There is also a risk that, despite not disclosing the portfolio holdings each day, some market participants may seek to use publically available information, including the VIIV, to identify the Fund’s investment strategy and engage in certain predatory trading practices that may have the potential to harm the Fund.

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 result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. In addition, due to the non-transparency of the portfolio a trading halt in a portfolio security could cause discrepancies between the VIIV and NAV of the Fund resulting in uncertainty on the part of the AP that results in wider, less liquid markets. Any security for which trading has been halted for an extended period of time will be disclosed on the Fund’s website, www.gabelli.com.

Automation Risk.    The Fund invests primarily in the equity securities of Automation Companies and, as such, is particularly vulnerable to risks inherent to those types of companies. These risks include, but are not limited to, small or limited markets for such securities, changes in business cycles, world economic growth, technological progress, rapid obsolescence and government regulation.

Authorized Participant and AP Representative Concentration Risk.    The creation and redemption process for the Fund occurs through a confidential brokerage account (“Confidential Account”) with an agent, called an AP Representative, on behalf of an Authorized Participant. Each day, the AP Representative will be given the names and quantities of the securities to be deposited, in the case of a creation, or redeemed, in

the case of a redemption (“Creation Basket”), allowing the AP Representative to buy and sell positions in the portfolio securities to permit creations or redemptions on the Authorized Participant’s behalf, without disclosing the information to the Authorized Participant. The Fund may have a limited number of institutions that act as Authorized Participants and AP Representatives, none of which are obligated to engage in creation or redemption transactions. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to process creation and/or redemption orders, Fund shares may trade at a discount to NAV and possibly face trading halts and/or delisting. This risk may be more pronounced in volatile markets, potentially where there are significant redemptions in ETFs, generally. The fact that the Fund is offering a novel and unique structure may affect the number of entities willing to act as Authorized Participants and AP Representatives. During times of market stress, Authorized Participants may be more likely to step away from this type of ETF than a traditional ETF.

Absence of an Active Market.    Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained by market makers or Authorized Participants. Authorized Participants are not obligated to execute purchase or redemption orders for Creation Units. Because this is a novel and unique structure, this could influence the number of entities willing to act as Authorized Participants. In periods of market volatility, market makers and/or Authorized Participants may be less willing to transact in Fund shares. The absence of an active market for the Fund’s shares may contribute to the Fund’s shares trading at a premium or discount to net asset value (“NAV”). If a shareholder purchases Fund shares at a time when the market price is at a premium to the NAV or sells Fund shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

New Fund Risk.    The Fund is new with a limited operating history and may have higher expenses. There can be no assurance that the Fund will grow to or maintain an economically viable size. The Fund could cease operations, and investors may be required to liquidate or transfer their assets at a loss. However, the expense limitation in place limits this risk through the end of its term.

Equity Risk.    Equity risk is the risk that the prices of the securities held by the Fund will change due to general market and economic conditions, perceptions regarding the industries in which the companies issuing the securities participate, and the issuer company’s particular circumstances.

American Depositary Receipts (“ADRs”) Risk.    Investment in ADRs does not eliminate all the risks inherent in investing in securities of non-U.S. issuers. The market value of ADRs is dependent upon the market value of the underlying securities and fluctuations in the relative value of the currencies in which the ADRs and the underlying securities are quoted.

Coronavirus (“COVID-19”) and Global Health Events.    COVID-19 and concerns about its rapid spread and infections have severely impacted business activity in virtually all economies, markets, and sectors and negatively impacted the value of many financial and other assets. The duration of the COVID-19 outbreak and its effects cannot be determined with certainty. These events could have a significant impact on the Fund’s performance, as well as the performance and viability of issuers in which it invests.

Issuer Risk.    The value of a security may decline for a number of reasons that directly relate to an issuer, such as management performance, financial leverage, and reduced demand for the issuer’s goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets or factors unrelated to the issuer’s value, such as investor perception.

Management Risk.    If the portfolio manager is incorrect in his assessment of the growth prospects of the securities the ETF holds, then the value of the Fund’s shares may decline.

Market Trading Risk.    Individual Fund shares may be purchased and sold only on a national securities exchange or alternative trading system through a broker-dealer, and may not be directly purchased or redeemed from the Fund. There can be no guarantee that an active trading market for shares will develop or be maintained, or that their listing will continue unchanged. Buying and selling shares may require you to pay brokerage commissions and expose you to other trading costs. Due to brokerage commissions and other transaction costs that may apply, frequent trading may detract from realized investment returns. Trading prices of shares may be above, at, or below the Fund’s NAV, will fluctuate in relation to NAV based on

supply and demand in the market for shares and other factors, and may vary significantly from NAV during periods of market volatility. The return on your investment will be reduced if you sell shares at a greater discount or narrower premium to NAV than when you acquired shares.

Technology Sector Risk.    Technology companies, may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by the loss or impairment of those rights. Companies in the technology sector are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.

Preferred Stock Risk.    Preferred stocks are susceptible to general market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. The dividend on a preferred stock may be changed or omitted by the issuer, and participation in the growth of an issuer may be limited.

Trading Issues Risk.    Trading in Fund shares on NYSE Arca, Inc. (“NYSE Arca”) may be halted in certain circumstances. There can be no assurance that the requirements of NYSE Arca necessary to maintain the listing of the Fund will continue to be met.
