**FUND SUMMARY – SIMPLIFY BOND BULL ETF**

**Investment Objective:** The Simplify Bond Bull ETF (the "Fund" or "RFIX") seeks to hedge interest rate movements arising from falling long-term interest rates, and to benefit from market stress when fixed income volatility increases, while providing the potential for income.

**Fees and Expenses of the Fund:** 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 table or example below.**

***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 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 upon these assumptions your costs would be:

---

| | | | |
|:---|:---|:---|:---|
| **1 Year** | **3 Years** | **5 Years** | **10 Years** |
| $51 | $160 | $280 | $628 |

---

***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 period December 9, 2024 (commencement of operations) through June 30, 2025, the Fund's portfolio turnover rate was 0% of the average value of its portfolio.

**Principal Investment Strategies:**

The Fund is an actively managed ETF. The Adviser seeks to achieve the Fund's investment objective by allocating the Fund's assets between:

● interest rate related derivatives and

● interest income producing debt instruments.

The Adviser expects to allocate assets among derivatives and debt instruments, depending upon market conditions. The Fund has adopted a non-fundamental policy that, under normal circumstances, the Fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in bonds and other debt securities and instruments that provide investment exposure to such debt securities, including derivatives such as swaptions, options and futures. Debt securities include U.S. Treasury securities, U.S. Treasury Inflation-Protected Securities ("TIPS"), exchange traded funds that primarily invest in U.S. Treasuries, TIPS, and investment grade bonds.

Generally, the Fund's strategy may be appropriate for investors who are seeking to hedge against falling interest rates. The Fund is designed investors with debt portfolios who may wish to hedge some of the risk of falling interest rates.

The Adviser seeks to achieve the interest rate hedging aspect of the Fund's investment objective by investing long in swaptions, interest rate options, and Treasury futures. Consequently, the Fund's portfolio will be highly sensitive to changes in interest rates. A swaption is an option to enter into a swap contract. The Fund may purchase receiver swaptions that give the Fund the option to enter into fixed interest rate swaps upon expiration of the swaption. These instruments have positive price sensitivity to falling interest rates. Similar to bond prices which typically rise when interest rates fall, it is expected that the Fund will benefit from swaption value increases, providing a hedge against the falling interest rate. Consequently, when viewed from a total return perspective, price gains in these instruments will tend to offset the effect of lower reinvestment rates caused by falling interest rates. These derivatives are selected to protect against falling long-term interest rates on high-quality instruments such as U.S. government securities and high-quality corporate debt. To select a derivative that it believes will produce the most effective hedge against falling interest rates, the Adviser assesses the interaction of maturity, strike price, reference interest rate, the risk-free rate, and volatility on the price of swaptions and interest rate options. While the investment focus of the interest rate related derivatives strategy is on gains from falling rates, to a lesser extent the Adviser's selection process is also intended to generate gains from option and swaption positions when interest rate volatility increases. Specifically, the Adviser will tend to increase allocations to swaptions and interest rate options when it believes interest rate volatility is poised to increase as these instruments become more valuable in higher volatility environments. The adviser rebalances derivative exposure after extreme rate movements (for example, 0.50%) or after the passage of time has significantly changed the rate sensitivity of a derivative. As time passes, swaptions and interest rate options become less sensitive to movements in the reference swap rate or interest rate. The Adviser does not take speculative positions based on its forecast for interest rates. The Fund limits net economic exposure at the time of investment to any one over-the-counter counterparty to 25% of Fund net assets.

The Adviser seeks to achieve the income aspect of the Fund's investment objective by investing U.S. Treasury securities, TIPS, exchange traded funds that primarily invest in U.S. Treasuries, TIPS, and investment grade bonds. TIPS are securities whose principal amount increases with inflation, as measured by the Consumer Price Index and are designed to protect investors from inflation risk. The Fund may purchase debt securities of any maturity.

When using various derivatives, the Fund may be required to post collateral to assure its performance. The Fund will hold cash and cash-like instruments or high-quality short term fixed income securities (collectively, "Collateral"). The Collateral may consist of (1) U.S. Government securities, such as bills, notes and bonds issued by the U.S. Treasury; (2) money market funds (including affiliated money market ETFs); (3) fixed income ETFs; and/or (4) corporate debt securities, such as commercial paper and other short-term unsecured promissory notes issued by companies that are rated investment grade or of comparable quality. The Adviser considers an unrated security to be of comparable quality to a security rated investment grade if it believes it has a similar low risk of default.

The Fund is classified as a "non-diversified" investment company under the Investment Company Act of 1940, as amended, which means that the Fund may invest a higher percentage of its assets in a fewer number of issuers than is permissible for a "diversified" Fund.

**Principal Investment Risks:** *As with all funds, there is the risk that you could lose money through your investment in the Fund. Many factors affect the Fund's net asset value and price of shares and performance.*

The following describes the principal risks the Fund bears with respect to its investments. As with any fund, there is no guarantee that the Fund will achieve its goal.

*Swaptions Risk.* A swaption is a contract that gives a counterparty the right (but not the obligation) to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. The Fund may purchase call swaptions. When the Fund purchases a swaption, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. Even if interest rates fall, swaptions may not increase in value as much as anticipated if volatility declines. These swaptions are highly sensitive to changes in interest rates.

*Active Management Risk.* The Fund is subject to the risk that the investment management strategy may not produce the intended results and may negatively impact Fund performance. The Adviser's strategy is highly sensitive to changes in interest rates.

*Cash or Cash Equivalents Risk.* At any time, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Fund's performance and the Fund may not achieve its investment objective.

*Volatility Risk*. Significant short-term price movements could adversely impact the performance of the Fund. The Fund's performance may be volatile, which means that the Fund's performance may be subject to substantial short-term changes up or down. In a rising rate environment, the Fund's losses could be substantial. The value of options and swaptions will tend to decline when volatility declines.

*U.S. Treasury and Agency Market Risk.* The U.S. Treasury and agency market can be volatile, and the value of instruments correlated with these markets may fluctuate dramatically from day to day. U.S. Treasury and agency obligations may provide relatively lower returns than those of other securities. Similar to other debt instruments, U.S. Treasury and agency obligations are subject to debt instrument risk and interest rate risk. In addition, changes to the financial condition or credit rating of the U.S. Government may cause the value of U.S. Treasury and agency obligations to decline.

*Counterparty Risk.* Counterparty risk is the risk that a counterparty to a financial instrument held by the Fund may become insolvent or otherwise fail to perform its obligations, and the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed.

*Derivatives Risk.* Options are a derivative investment. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities.

*Futures Risk.* The successful use of futures contracts draws upon the Adviser's skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures contracts are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (b) possible lack of a liquid secondary market; (c) investments in futures contracts involves leverage, which means a small percentage of assets in futures can have a disproportionately large impact on the Fund (d) losses caused by unanticipated market movements; (e) the Adviser's inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors.

*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. 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.

*ETF Structure Risks.* The Fund is structured as an ETF. As a result, the Fund is subject to special risks, including:

● *Not Individually Redeemable.* The Fund's shares ("Shares") are not redeemable by retail investors and may be redeemed only by Authorized Participants at net asset value ("NAV") and only in Creation Units. A retail investor generally incurs brokerage costs when selling shares.

● *Trading Issues*. Trading in Shares on NYSE Arca, Inc. (the "Exchange") may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable, such as extraordinary market volatility. There can be no assurance that Shares will continue to meet the listing requirements of the Exchange which may result in the Shares being delisted. An active trading market for the Shares may not be developed or maintained. If the Shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Shares.

● *Market Price Variance Risk.* The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares and will include a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the Shares. There may be times when the market price and the NAV vary significantly. This means that Shares may trade at a discount to NAV.

○ In times of market stress, market makers may step away from their role market making in the Shares and in executing trades, which can lead to differences between the market value of the Shares and the Fund's NAV.

○ The market price of the Shares may deviate from the Fund's NAV, particularly during times of market stress, with the result that investors may pay significantly more or significantly less the Shares than the Fund's NAV, which is reflected in the bid and ask price for the Shares or in the closing price.

○ In stressed market conditions, the market for the Shares may become less liquid in response to the deteriorating liquidity of the Fund's portfolio. This adverse effect on the liquidity of the Shares may, in turn, lead to differences between the market value of the Shares and the Fund's NAV.

● *Authorized Participant Risk.* Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as an Authorized Participant on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Fund shares may be more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.

 

*Fixed Income Securities Risk.* When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund's share price and total return to be reduced and fluctuate more than other types of investments.

*Leverage Risk.* The use of leverage by the Fund, such as borrowing money to purchase securities or the use of options, will cause the Fund to incur additional expenses and magnify the Fund's gains or losses.

*Limited History Risk.* The Fund is a new ETF and has a limited history of operations for investors to evaluate.

*Market and Geopolitical Risk*. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund's portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long term effects on both the U.S. and global financial markets.

*Non-Diversified Fund Risk.* Because the Fund is non-diversified and may invest a greater portion of its assets in fewer issuers than a diversified fund, changes in the market value of a single portfolio holding could cause greater fluctuations in the Fund's share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a single portfolio holding or a relatively small number of portfolio holdings to have a greater impact on the Fund's performance.

*Option Risk.* There are risks associated with the purchase of call options. As the buyer of a call option, the Fund risks losing the entire premium invested in the option if the Fund does not exercise the option. Option prices tend to decline when volatility declines. The type of options the Fund may use are highly sensitive to changes in interest rates.

*Over-the-Counter Market Risk.* Securities and options traded in over-the-counter markets may trade less frequently and in limited volumes and thus exhibit more volatility and liquidity risk, and the prices paid by the Fund in over-the-counter transactions may include an undisclosed dealer markup. The Fund is also exposed to default by the over-the-counter option writer who may be unwilling or unable to perform its contractual obligations to the Fund.

*Premium/Discount Trading Risk.* The Fund may trade at greater than 2% premium to its NAV because of typical bid-offer spreads for OTC products and a credit support annex that is specific to a fund registered under the 1940 Act. In periods of outflows, the Fund may trade at greater than 2% discount to its NAV for the same reason. Such variations in the premium or discount may have disparate effects on certain shareholders. Shareholders who purchase shares on the secondary market at a premium to NAV may lose disproportionate value if the Fund begins trading at a discount. Similarly, Authorized Participants who wish to redeem creation units at NAV may receive a basket with a per share value below that of the current trading price of the Fund.

*Underlying Fund Risk.* ETFs and ETPs in which the Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in the ETFs and ETPs and may be higher than other funds that invest directly in stocks and bonds. Each of the ETFs and ETPs is subject to its own specific risks, but the adviser expects the principal investments risks of such ETFs will be similar to the risks of investing in the Fund.

*Affiliated Money Market ETF Conflict of Interest Risk.* Because the Fund may invest in an affiliated ETF, the Adviser is subject to conflicts of interest in allocating the Fund's assets to the affiliated ETF. The Adviser will receive more revenue to the extent it selects an affiliated ETF rather than an unaffiliated ETF for inclusion in the Fund's portfolio.

**Performance:** Performance information will be available in the prospectus after the Fund has been in operation for one full calendar year. Past performance is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost by visiting www.simplify.us/etfs or by calling 1 (855) 772-8488.

**Investment Adviser:** Simplify Asset Management Inc. (the "Adviser").

**Portfolio Managers:** David Berns, Chief Investment Officer of the Adviser, and Ken Miller, Portfolio Manager of the Adviser serve as portfolio managers of the Fund. Dr. Berns and Mr. Miller have each served the Fund as a portfolio manager since it commenced operations and are jointly and primarily responsible for the management of the Fund.

**Purchase and Sale of Fund Shares:** The Fund will issue and redeem Shares at NAV only in large blocks of 25,000 Shares (each block of Shares is called a "Creation Unit"). Creation Units are issued and redeemed primarily in-kind for securities but may include cash. Individual Shares may only be purchased and sold in secondary market transactions through brokers. Except when aggregated in Creation Units in transactions with Authorized Participants, the Shares are not redeemable securities of the Fund.

Shares of the Fund are listed for trading on the Exchange and trade at market prices rather than NAV. Shares of the Fund may trade at a price that is greater than, at, or less than NAV.

**Tax Information:** The Fund's distributions generally will be taxable as ordinary income or long-term capital gains. A sale of Shares may result in capital gain or loss.

**Payments to Broker-Dealers and Other Financial Intermediaries:** If you purchase 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 website for more information.
