Diversified Credit Portfolio of ETFs Series 25

The Trust will invest at least 80% of the value of its assets in shares of ETFs that invest substantially all of their assets in fixed-income securities of varying credit qualities and maturities. Such fixed-income securities may include convertible securities, senior loans, floating-rate instruments, mortgage-backed securities and municipal bonds. Some of the ETFs may not be diversified funds.

The Trust may also invest in ETFs that invest substantially all of their assets in preferred securities ("preferred ETFs"). The fixed-income and/or preferred ETFs included in the Trust’s portfolio invest in a wide range of debt and preferred securities rated below investment-grade through investment-grade or may be unrated but deemed to be of comparable quality by an ETF’s adviser. High-yield, below investment-grade securities or “junk” bonds are considered to be primarily speculative with respect to the issuer’s ability to make principal and interest payments and may be more volatile than higher rated securities of similar maturity. Additionally, they are subject to greater market, credit and liquidity risks than investment-grade securities.

The fixed-income and/or preferred ETFs included in the Trust’s portfolio invest in debt and/or preferred securities across all maturities. Typically, fixed-income securities with longer periods before maturity are more sensitive to interest rate changes.

The fixed-income and/or preferred ETFs included in the trust’s portfolio may invest in foreign securities, including securities issued by companies headquartered or incorporated in countries considered to be emerging markets. Whether a security is deemed to be foreign is generally determined by a combination of the security’s issuer’s country of incorporation and the primary listing of the security; however, if these two factors differ, the location of the issuer’s sales and assets is also considered. An emerging market country is generally defined as a developing country with low per capita income in the initial stages of its industrialization cycle.

As of the date of deposit, this trust will hold a significant amount of its assets in diversified and non-diversified ETFs that invest in investment-grade securities, high-yield securities, floating rate instruments and/or foreign securities, which include emerging markets.

The Sponsor, with the assistance of Guggenheim Partners Investment Management, LLC (“GPIM”), has selected a portfolio of ETFs believed to have the best potential for current income while taking into consideration risks and opportunities that align with GPIM’s macroeconomic outlook. When selecting the ETFs for the Trust, the Sponsor considers a number of factors including, but not limited to, the size, liquidity and daily trading volume, the current dividend yield, average duration, level of credit exposure, the strategy and investment objective, the expense ratio and limitations on the overlap of the underlying securities held by the ETFs.

As with all investments, you may lose some or all of your investment in the Trust. No assurance can be given that the Trust’s investment objective will be achieved. The Trust also might not perform as well as you expect. This can happen for reasons such as these:

• Securities prices can be volatile. The value of your investment may fall over time. Market value fluctuates in response to various factors. These can include stock market movements, purchases or sales of securities by the Trust, government policies, litigation, and changes in interest rates, inflation, the financial condition of the securities’ issuer or even perceptions of the issuer. Changes in legal, political, regulatory, tax and economic conditions may cause fluctuations in markets and securities prices, which could negatively impact the value of the Trust. Additionally, event such war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may adversely affect the economy, various markets and issuers. An outbreak of a novel form of coronavirus disease (“COVID-19”) was first detected in December 2019 and rapidly spread around the globe leading the World Health Organization to declare the COVID-19 outbreak a pandemic in March 2020 and resulting in major disruptions to economies and markets around the world. The complete economic impacts of COVID-19 are not yet fully known. The COVID-19 pandemic, or any future public health crisis, is impossible to predict and could result in adverse market conditions which may negatively impact the performance of the trust and the trust's ability to achieve its investment objectives. Units of the trust are not deposits of any bank and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
• Share prices or distributions on the securities in the Trust may decline during the life of the Trust. There is no guarantee that share prices of the securities in the Trust will not decline and that the issuers of the securities will declare distributions in the future and, if declared, whether they will remain at current levels or increase over time.
• The Trust invests in shares of ETFs. ETFs are investment pools that hold other securities. The ETFs in the Trust are usually passively-managed index funds that seek to replicate the performance or composition of a recognized securities index. ETFs are subject to various risks, including management’s ability to meet the fund’s investment objective. Shares of ETFs may trade at a premium or discount from their net asset value in the secondary market. If the Trust has to sell an ETF share when the share is trading at a discount, the Trust will receive a price that is less than the ETF’s net asset value. This risk is separate and distinct from the risk that the net asset value of the ETF shares may decrease. The amount of such discount from net asset value is subject to change from time to time in response to various factors. The underlying ETF has management and operating expenses. Consequently, you will bear not only your share of your Trust’s expenses, but also the expenses of the underlying ETFs. By investing in ETFs, the Trust incurs greater expenses than you would incur if you invested directly in the ETFs.
• The ETFs are subject to annual fees and expenses, including a management fee. Unitholders of the Trust will bear these fees in addition to the fees and expenses of the Trust. See “Fees and Expenses” for additional information.
• The Trust is subject to an ETF’s index correlation risk. To the extent that an underlying ETF is an index tracking ETF, Index correlation risk is the risk that the performance of an ETF will vary from the actual performance of the fund’s target index, known as “tracking error.” This can happen due to fund expenses, transaction costs, market impact, corporate actions (such as mergers and spin-offs) and timing variances.
• The value of the fixed-income securities ETFs will generally fall if interest rates, in general, rise. Typically, fixed-income securities with longer periods before maturity are more sensitive to interest rate changes. The Trust may be subject to greater risk of rising interest rates than would normally be the case due to the current economic environment and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives.
• An ETF or an issuer of securities held by an ETF may be unwilling or unable to make principal payments and/or to declare distributions in the future, may call a security before its stated maturity, or may reduce the level of distributions declared. Issuers may suspend dividends during the life of the Trust. This may result in a reduction in the value of your units.
• The financial condition of an ETF or an issuer of securities held by an ETF may worsen, resulting in a reduction in the value of your units. This may occur at any point in time, including during the primary offering period. As the Trust is unmanaged, a downgraded security will remain in the portfolio.
• Economic conditions may lead to limited liquidity and greater volatility. The markets for fixed-income securities, such as those held by certain ETFs, may experience periods of illiquidity and volatility. General market uncertainty and consequent repricing risk have led to market imbalances of sellers and buyers, which in turn have resulted in significant valuation uncertainties in a variety of fixed-income securities. These conditions resulted, and in many cases continue to result in, greater volatility, less liquidity, widening credit spreads and a lack of price transparency, with many debt securities remaining illiquid and of uncertain value. These market conditions may make valuation of some of the securities held by an ETF uncertain and/or result in sudden and significant valuation increases or declines in its holdings.
• Certain ETFs held by the trust invest in senior loans. Borrowers under senior loans may default on their obligations to pay principal or interest when due. This non-payment would result in a reduction of income to the applicable ETF, a reduction in the value of the senior loan experiencing non-payment and a decrease in the net asset value of the ETF. Although senior loans in which the ETFs invest may be secured by specific collateral, there can be no assurance that liquidation of collateral would satisfy the borrower’s obligation in the event of non-payment of scheduled principal or interest or that such collateral could be readily liquidated. Senior loans in which the ETFs invest:
  — generally are of below investment-grade or “junk” credit quality;
  — may be unrated at the time of investment;
  — may be floating-rate instruments in which the interest rate payable on the obligations fluctuates on a periodic basis based upon changes in the base lending rate;
  — generally are not registered with the Securities and Exchange Commission (“SEC”) or any state securities commission; and
  — generally are not listed on any securities exchange.
  In addition, the amount of public information available on senior loans generally is less extensive than that available for other types of assets. The senior loans in which the ETFs invest generally are of below investment-grade or “junk” credit quality and therefore are speculative and are subject to greater market, credit and liquidity risks than investment-grade securities. Furthermore, senior loans are generally illiquid. Transactions in senior loans may take longer than seven days to settle which could affect the underlying Closed-End Funds' and ETFs' ability to manage the liquidity of their portfolios. Certain senior loans in which an ETF may invest are subject to rates that are tied to an interest rate. Historically, many senior loans were tied to the
  (“LIBOR”). Since June 30, 2023,London Interbank Offered Rate LIBOR settings have ceased to be published on a representative basis. Certain replacement rates have been identified and other replacement rates could be adopted by market participants. It is not possible to predict the effect of any replacement rates. Any potential effects of the transition away from LIBOR on certain instruments in which an ETF invests can be difficult to ascertain, and they may vary depending on
  factors that include, but are not limited to: (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments. Any effects
  of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to an ETF holding senior loans.
• Certain ETFs held by the trust invest in securities that are structured as floating-rate instruments. The yield on these securities will generally decline in a falling interest rate environment, causing the ETFs to experience a reduction in the income they receive from these securities. A sudden and significant increase in market interest rates may increase the risk of payment defaults and cause a decline in the value of these investments and the value of the ETFs held by the trust.                Many of the floating-rate securities in which an ETF may invest are subject to rates that are tied to an interest rate. Historically, many floating-rate securities were tied to the London Interbank Offered Rate (“LIBOR”). Since June 30, 2023, LIBOR settings have ceased to be published on a representative basis. Certain replacement rates have been identified and other replacement rates could be adopted by market participants. It is not possible to predict the effect of any replacement rates. Any potential effects of the transition away from LIBOR on certain instruments in which an ETF invests can be difficult to ascertain, and they may vary depending on factors that include, but are not limited to: (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments. Any effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to an ETF holding floating-rate securities.
• Certain ETFs held by the trust invest in mortgage-backed securities. Mortgage-backed securities represent direct or indirect participations in, or are secured by and payable from, mortgage loans secured by real property and can include single- and multi-class passthrough securities and collateralized mortgage obligations. Unscheduled or early payments of principal and interest on the underlying mortgages may make the securities' effective maturity shorter than anticipated. Rising interest rates tend to extend the duration of mortgage-backed securities, making them more sensitive to changes in interest rates, and may reduce the market value of the securities. In addition, mortgage-backed securities are subject to prepayment risk, the risk that borrowers may pay off their mortgages sooner than expected, particularly when interest rates decline. This can reduce the ETFs’, and therefore the trust’s, returns because the ETFs may have to reinvest that money at lower prevailing interest rates.
• Certain ETFs held by the Trust invest in securities that are rated below investment-grade and are considered to be “junk” securities. Below investment-grade obligations are considered to be primarily speculative with respect to the issuer’s ability to make principal and interest payments and may be more volatile than higher rated securities of similar maturity. Additionally, they are subject to greater market, credit and liquidity risks than investment-grade securities. Accordingly, the risk of non-payment or default is higher than with investment-grade securities. In addition, such securities may be more sensitive to interest rate changes and more likely to receive early returns of principal in falling rate environments.
• Certain ETFs held by the Trust may invest in securities that are rated as investment-grade by only one rating agency. As a result, such split-rated securities may have more speculative characteristics and are subject to a greater risk of default than securities rated as investment-grade by more than one rating agency.
• Certain ETFs held by the Trust invest in foreign securities. Investment in foreign securities presents additional risk. Foreign risk is the risk that foreign securities will be more volatile than U.S. securities due to such factors as adverse economic, currency, political, social or regulatory developments in a country, including government seizure of assets, excessive taxation, limitations on the use or transfer of assets, the lack of liquidity or regulatory controls with respect to certain industries or differing legal and/or accounting standards.
• Certain ETFs held by the Trust invest in securities issued by companies headquartered or incorporated in countries considered to be emerging markets. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. Financial and other reporting by companies and government entities also may be less reliable or difficult to obtain in emerging market countries. In addition, foreign investors are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries. Risks of investing in developing or emerging countries also include the possibility of investment and trading limitations, delays and disruptions in settlement transactions, market manipulation concerns, political uncertainties and dependence on international trade and development assistance.
• Certain ETFs held by the Trust invest in securities whose value may be dependent on currency exchange rates. The U.S. dollar value of these securities may vary with fluctuations in foreign exchange rates. Most foreign currencies have fluctuated widely in value against the U.S. dollar for various economic and political reasons such as the activity level of large international commercial banks, various central banks, speculators, hedge funds and other buyers and sellers of foreign currencies.
• Certain ETFs held by the Trust are non-diversified. A non-diversified fund may invest a larger portion of its assets in the securities of a limited number of issuers and may be more sensitive to
  any single economic, business, political or regulatory occurrence affecting an issuer than a diversified fund. Poor performance by any one of these issuers would adversely affect the fund to a greater extent than a more broadly diversified fund.
• The Sponsor does not actively manage the portfolio. The Trust will generally hold, and may, when creating additional units, continue to buy, the same securities even though a security’s outlook, market value or yield may have changed.
• Inflation may lead to a decrease in the value of assets or income from investments.
• The Trust may be susceptible to potential risks through breaches in cybersecurity. A breach in cybersecurity refers to both intentional and unintentional events that may cause the Trust to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Sponsor of the Trust to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cybersecurity breaches of the Trust’s third-party service providers, or issuers in which the Trust invests, can also subject the Trust to many of the same risks associated with direct cybersecurity breaches.
• The Trust is subject to risks arising from various operational factors and their service providers. Operational factors include, but not limited to, human error, processing and communication errors, errors of the Trust’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. Additionally, the Trust may be subject to the risk that a service provider may not be willing or able to perform their duties as required or contemplated by their agreements with the Trust. Although the Trust seeks to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
