**FUND SUMMARY – SIMPLIFY MBS ETF**

**Investment Objective:** The Simplify MBS ETF (the "Fund" or "MTBA") seeks to maximize total return.

**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 on the purchase and sale of Fund shares, which are not reflected in the tables and examples below.**

---

| | |
|:---|:---|
| **Annual Fund Operating Expenses**<br> (expenses that you pay each year as a percentage of the value of your investment) | |
| Management Fees | 0.25% |
| Distribution and Service (12b-1) Fees | 0.00% |
| Total Annual Fund Operating Expenses | 0.25% |
| Fee Waiver<sup>(1)</sup> | (0.10)% |
| Total Annual Fund Operating Expenses After Fee Waiver | 0.15% |

---

(1) The Fund's adviser has contractually agreed, through at least October 31, 2026, to waive its management fees to 0.15% of the Fund's average daily net assets. This agreement may be terminated only by the Trust's Board of Trustees on 60 days' written notice to the Fund's adviser.

***Example:*** This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other 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. The Example further assumes that the Fund's fee waiver agreement will only be in place for the term specified above. 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** |
| $15 | $70 | $131 | $308 |

---

***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 1376% of the average value of its portfolio.

**Principal Investment Strategies:**

The Fund has adopted a non-fundamental policy that, under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in mortgage-backed securities ("MBS"). The Fund defines MBS as any agency or non-agency residential or commercial mortgage-backed security and any futures contract, forward agreement, swap contract, or option linked to the preceding The Fund is an actively managed exchange-traded fund that seeks to achieve its investment objectives by investing primarily in MBS's issued by the Government National Mortgage Association ("GNMA"), Federal National Mortgage Association ("FNMA") and Federal Home Loan Mortgage Corporation ("FHLMC"). These agencies securitize pools of mortgage loans that meet the underwriting standards of the relevant agency. The Fund may also purchase MBS on a when-issued basis, (commonly referred to as "To Be Announced" or "TBA"); and gain exposure to MBS through derivatives such as options or swap agreements. These are included as MBS for purposes of the Fund's 80% investment policy. The Fund is deemed to be concentrated because it invests more than 25% of its net assets in MBS.

Generally, the Adviser constructs the Fund's portfolio by selecting instruments that it believes will produce the highest yield while maintaining a medium-term (3-10 years) effective duration portfolio. The Adviser considers price, coupon, expected prepayment rate and maturity to calculate a security's expected yield. Effective duration measures the interest rate sensitivity of a security including the borrower's option to prepay its mortgage loan. For example, an effective duration of "five years" means that a security's price would be expected to decrease by approximately 5% with a 1% increase in interest rates. The Adviser sells securities to manage effective duration or when a more attractive instrument becomes available.

To generate additional returns, the Adviser may use a strategy referred to as a dollar roll. In a dollar, the Fund sells, in the TBA market, a security for current month settlement, while simultaneously committing to buy a substantially similar TBA security for next month or a further month settlement. The Adviser assesses the relative prices between delivery months as well as interest income on short-term investments to forecast the expected profit of this strategy, which creates investment leverage.

The Fund also holds cash and invests in cash-equivalents (money market funds, including affiliated money market ETFs) or high-quality short term fixed income securities as collateral for swaps. The Fund uses mortgage security linked swaps as a form of MBS investment and interest rate linked swaps to manage duration exposure and/or to hedge interest rate risk.

**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.

*Mortgage-Related Risks*. MBS represent interests in "pools" of mortgages and often involve risks that are different from or possibly more acute than risks associated with other types of debt instruments. Generally, rising interest rates tend to extend the duration of fixed rate mortgage-related securities, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, the Fund may exhibit additional volatility since individual mortgage holders are less likely to exercise prepayment options, thereby putting additional downward pressure on the value of these securities and potentially causing the Fund to lose money. This is known as extension risk. MBS can be highly sensitive to rising interest rates, such that even small movements can cause an investing Fund to lose value. When interest rates decline, borrowers may pay off their mortgages sooner than expected. This can reduce the returns of a Fund because the Fund may have to reinvest that money at the lower prevailing interest rates. This is known as prepayment risk.

*TBA Securities Risk*. In a TBA transaction, a seller agrees to deliver a security at a future date, but does not specify the particular security to be delivered. Instead, the seller agrees to accept any security that meets specified terms. TBA transactions involve the risk that the securities received may have less favorable characteristics than what was anticipated when the Fund entered into the transaction. TBA transactions are also subject to counterparty risk and will be exposed to changes in the value of the underlying investments during the term of the agreement.

*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. U.S. Treasury obligations are backed by the "full faith and credit" of the U.S. government and are generally considered to have negligible credit risk. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government.

*Fixed Income Securities Risk.* Fixed income risk factors include credit risk (the debtor may default) and prepayment risk (the debtor may pay its obligation early or later than expected, potentially reducing the amount of interest payments or extending time to principal repayment). These risks could affect the value of a particular investment possibly causing the Fund's share price and total return to be reduced and fluctuate more than other types of investments. When a Fund invests in fixed income securities the value of your investment in a 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 debt securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. If the U.S. Federal Reserve's Federal Open Market Committee ("FOMC") raises the federal funds interest rate target, interest rates across the U.S. financial system may rise. However, the magnitude of rate changes across maturities and borrower sectors is uncertain. Rising rates may decrease liquidity and increase volatility, which may make portfolio management more difficult and costly to a Fund and its shareholders. Additionally, default risk increases if issuers must borrow at higher rates. Generally, these changing market conditions may cause a Fund's share price to fluctuate or decline more than other types of equity investments.

*Active Management Risk.* The Fund is subject to the risk that its investment management strategy may not produce the intended results. There can be no assurance that the securities selected by the adviser will produce positive returns.

*Concentration Risk.* The Fund's net asset value may fluctuate more than that of a fund that does not concentrate in MBS.

*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.

*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.

*Counterparty Risk.* The Fund may engage in transactions in securities and financial instruments that involve counterparties. Counterparty risk is the risk that a counterparty (the other party to a transaction or an agreement or the party with whom the Fund executes transactions) to a transaction with the Fund may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise honor its obligations. To limit the counterparty risk associated with such transactions, the Fund conducts business only with financial institutions judged by the Adviser to present acceptable credit risk.

*Derivatives Risk.* The Fund's 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 fulfil 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.

*Dollar Roll Risk*. Dollar rolls involve the risk that the Fund's counterparty will be unable to deliver the mortgage-backed securities underlying the dollar roll at the fixed time. If the buyer files for bankruptcy or becomes insolvent, the buyer or its representative may ask for and receive an extension of time to decide whether to enforce the Fund's repurchase obligation. In addition, the Fund earns interest by investing the transaction proceeds during the roll period. Dollar roll transactions have the effect of creating leverage in the Fund's portfolio.

*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 a Fund from buying or selling certain securities or financial instruments. In these circumstances, a Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and may incur substantial trading losses.

*ETF Structure Risk:* The Fund is structured as an ETF and will invest in underlying ETFs. As a result, the Fund is subject to special risks, including:

● *Not Individually Redeemable*. A Fund's Shares ("Shares") are not redeemable by retail investors and may be redeemed only by the Authorized Participant 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 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 a Fund's 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*. Individual Shares of a Fund that are listed for trading on the Exchange can be bought and sold in the secondary market at market prices. The market prices of Shares will fluctuate in response to changes in NAV and supply and demand for Shares. There may be times when the market price and the NAV vary significantly and you may pay more than NAV when buying Shares on the secondary market, and you may receive less than NAV when you sell those Shares. The market price of Shares, like the price of any exchange-traded security, includes a "bid-ask spread" charged by the exchange specialists, market makers or other participants that trade the particular security. In times of severe market disruption, the bid-ask spread often increases significantly. This means that Shares may trade at a discount to NAV and the discount is likely to be greatest when the price of Shares is falling fastest, which may be the time that you most want to sell your Shares. A Fund's investment results are measured based upon the daily NAV of a Fund over a period of time. Investors purchasing and selling Shares in the secondary market may not experience investment results consistent with those experienced by those Authorized Participants creating and redeeming directly with a Fund.

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

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

● *Authorized Participant Risk.* Only an Authorized Participant may engage in creation or redemption transactions directly with a Fund. A 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 a Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, a Fund's shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for securities or instruments that have lower trading volumes.

*Leverage Risk.* Using derivatives can create leverage, which can amplify the effects of market volatility on the Fund's share price and make the Fund's returns more volatile. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The use of leverage may also cause the Fund to have higher expenses than those of other funds that do not use such techniques. MBS futures, forwards, swaps, and options are subject to leverage risk because they require only a small margin deposit or purchase price relative to the notional amounts of MBS they represent.

*Limited History of Operations.* The Fund is a relatively new ETF and has 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 a Fund's portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, climate change or climate related events, natural disasters, 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.

*Options Risk.* When the Fund purchases a call option, it receives, in return for the premium it pays, the right to buy from the writer of the option the underlying security at a specified price at any time before the option expires. The Fund purchases call options in anticipation of an increase in the market value of securities that it intends ultimately to buy. During the life of the call option, a Fund is able to buy the underlying security at the exercise price regardless of any increase in the market price of the underlying security. In order for a call option to result in a gain, the market price of the underlying security must exceed the sum of the exercise price, the premium paid, and transaction costs.

*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 a Fund in over-the-counter transactions may include an undisclosed dealer markup. Each 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 a Fund.

*Swap Risk.* Swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to hedge or replace. Over the counter swaps are subject to counterparty default. Leverage inherent in derivatives will tend to magnify the Fund's losses.

*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.

**Performance:** The following performance information provides some indication of the risks of investing in the Fund. The bar chart shows the Fund's performance from year to year. The table shows how the Fund's average annual total returns compare with those of a broad-based securities market index and an additional index. The additional index tracks U.S. agency mortgage-backed securities and is included as a performance benchmark relevant to the Fund's MBS investment strategy. The Fund's past performance (before and after taxes) 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.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates during the period covered by the table above 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. After-tax returns shown are not relevant to investors who hold shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts.

**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 in November 2023 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. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market. Recent information on the Fund's NAV, market price, premiums and discounts, and bid-ask spreads is available at www.simplify.us/etfs.

**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.
