Specialty Gas Industry Risk. The Specialty Gas industry includes companies engaged in gas exploration and production (including integrated gas exploration), gas refining and marketing, and gas storage and transportation. The prices of the securities of companies in the Specialty Gas industry may fluctuate widely due to supply and demand for a specific product or service, the price of gas, exploration and production spending, world events, and economic conditions. Natural disasters and changes in exchange rates and interest rates also may affect companies in the Specialty Gas Industry. The regulatory environment, taxation policies, and the economies of the key helium and specialty gas production countries also may affect the prices of the securities in the Specialty Gas industry. Legislative or regulatory changes and increased government supervision also may affect companies in the Specialty Gas industry.

Focused Portfolio Risk. The Fund will hold a relatively focused portfolio that may contain exposure to the securities of fewer issuers than the portfolios of other ETFs. Holding a relatively focused portfolio may increase the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

Data Risk. The composition of the Index is heavily dependent on information and data supplied by third parties (“Data”). When Data proves to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Index universe that would have been excluded or included had the Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can be expected to also reflect the errors.

Tracking Error Risk. While the Fund generally seeks to track the performance, before fees and expenses, of the Index, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

Management Risk. The risk that the investment techniques and risk analyses applied by the investment adviser will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to the investment adviser and the individual portfolio manager in connection with managing the Fund. There is no guarantee that the investment objective of the Fund will be achieved.

Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the underlying reference asset and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks:

Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the underlying security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return.

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets, securities, or instruments. The gross return to be exchanged or “swapped” between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in the reference asset.

If the underlying security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established.

Certain of the swap agreements entered into by the Fund may be unfunded total return swaps, pursuant to which the Fund does not make an initial investment of the full notional amount of the swap. As a result, the Fund is exposed to the risk that its counterparty will be unable to meet its obligations under the swap agreement, and the Fund’s exposure to a counterparty generally equals the net amount owed to the Fund based on the daily change in value of the reference asset. In the event of a counterparty default or insolvency, the Fund may incur losses in excess of the collateral, if any, posted by the counterparty, and the timing and amount of any recovery may be uncertain. In addition, the use of unfunded swap agreements may create economic leverage for the Fund, which may magnify gains and losses and increase the volatility of the Fund’s returns.

Counterparty Risk. To the extent contemplated by its investment strategy, the Fund may use derivative instruments, such as options, swaps, futures contracts and other instruments, to obtain or manage investment exposure. Derivatives may be subject to counterparty risk, meaning the risk that a counterparty, clearing member or clearing house will be unwilling or unable to perform its obligations to the Fund due to bankruptcy, insolvency, financial distress, operational failure or other default. If a counterparty or clearing member defaults, the Fund may lose the expected benefit of the transaction, experience delays or costs in recovering collateral or other amounts owed to it, or be required to enter into replacement transactions on less favorable terms, if at all. The Fund also may be unable to implement its investment strategy effectively if suitable counterparties or clearing members are unavailable.

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Costs of Buying or Selling Shares. Buying or selling Shares involves certain costs, including brokerage commissions, other charges imposed by brokers, and bid-ask spreads. The bid-ask spread represents the difference between the price at which an investor is willing to buy Shares and the price at which an investor is willing to sell Shares. The spread varies over time based on the Shares’ trading volume and market liquidity. The spread is generally lower if Shares have more trading volume and market liquidity and higher if Shares have little trading volume and market liquidity. Due to the costs of buying or selling Shares, frequent trading of Shares may reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

Economic and 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 the 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, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. 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. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets.

Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund.

New Fund Risk. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions.

Newly Public Company Risk. The Fund may obtain exposure to publicly traded companies that have recently completed an initial public offering (“IPO”), as well as operating companies resulting from completed SPAC business combinations, to the extent such companies are included in the Index. Companies that have recently become publicly traded may be unseasoned and may have limited trading histories, track records of reporting to investors, and research coverage. Their securities may experience significant price volatility and may be subject to greater liquidity risk. In addition, significant holdings by venture capital, private equity or other pre-public investors may become eligible for sale following the expiration of applicable lock-up periods, which may result in increased volatility or downward pressure on the market price of such securities.

Underlying Index Risk. Neither the Fund’s investment adviser nor the Index Provider is able to guarantee the continuous availability or timeliness of the production of the Index. The calculation and dissemination of the Index values may be delayed if the information technology or other facilities of the Index Provider, calculation agent, data providers and/or relevant stock exchange malfunction for any reason. A significant delay may cause trading in shares of the Fund to be suspended. Errors in Index data, computation and/or the construction in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider, calculation agent or other applicable party for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.
