Investment Objective

The SPDR MarketAxess Investment Grade 400 Corporate Bond ETF (the "Fund") seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of an index that tracks the investment grade U.S. corporate bond market.

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund ("Fund Shares"). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):

Management fees	0.09%
Distribution and service (12b-1) fees	None
Other expenses1	0.00%
Total annual Fund operating expenses	0.09%
Less contractual fee waiver2	(0.02)%
Net annual Fund operating expenses	0.07%

1

"Other expenses" are based on estimated amounts for the current fiscal year.

SSGA Funds Management, Inc. (the "Adviser") has contractually agreed to waive a portion of its management fee and/or reimburse certain expenses, until May 11, 2023, so that the net annual Fund operating expenses, before application of any fees and expenses not paid by the Adviser pursuant to the Investment Advisory Agreement, if any, will be limited to 0.07% of the Fund's average daily net assets. The contractual fee waiver does not provide for the recoupment by the Adviser of any fees the Adviser previously waived. The Adviser may continue the waiver and/or reimbursement from year to year, but there is no guarantee that the Adviser will do so and the waiver and/or reimbursement may be cancelled or modified at any time after May 11, 2023. This waiver and/or reimbursement may not be terminated prior to May 11, 2023 except with the approval of the Fund's Board of Trustees.

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 sell or hold all of your Fund 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 reflects the Fund's contractual fee waiver and/or expense reimbursement only in the periods for which the contractual fee waiver and/or expense reimbursement is expected to continue. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Year 1	Year 3
$7	$27

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. The Fund had not commenced operations as of the date of this Prospectus and, as a result, does not yet have a portfolio turnover rate.

The Fund's Principal Investment Strategy

In seeking to track the performance of the MarketAxess U.S. Investment Grade 400 Corporate Bond Index (the "Index"), the Fund employs a sampling strategy, which means that the Fund is not required to purchase all of the securities represented in the Index. Instead, the Fund may purchase a subset of the securities in the Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the Index. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. Based on its analysis of these factors, SSGA Funds Management, Inc. ("SSGA FM" or the "Adviser"), the investment adviser to the Fund, either may invest the Fund's assets in a subset of securities in the Index or may invest the Fund's assets in substantially all of the securities represented in the Index in approximately the same proportions as the Index, as determined by the Adviser to be in the best interest of the Fund in pursuing its objective.

Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index and in securities that the Adviser determines have economic characteristics that are substantially identical to the economic characteristics of the securities that comprise the Index. In addition, in seeking to track the Index, the Fund may invest in debt securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by the Adviser). In seeking to track the Index, the Fund's assets may be concentrated in an industry or group of industries, but only to the extent the Index concentrates in a particular industry or group of industries. The Fund may use derivatives, including credit default swaps and credit default index swaps, to obtain investment exposure that the Adviser expects to correlate closely with the Index, or a portion of the Index, and in managing cash flows.

The Index is designed to measure the performance of 400 U.S. dollar denominated investment grade corporate bonds with higher-than-average liquidity relative to the broader U.S. corporate bond market. In order to be included in the Index, a bond must have a corporate bond classification from Refinitiv. Bonds included in the Index must also, as of the Index Determination Date (defined below), (i) be rated investment grade, (ii) be issued in the U.S. by an issuer that is U.S. or non-U.S. domiciled, (iii) be U.S. dollar denominated, (iv) have $300 million or more of par amount outstanding, (v) have a remaining maturity of at least 2 years, (vi) have an issue date prior to the month of the Index Determination Date (as defined below), and (vii) have a fixed rate (which includes fixed-to-floating rate bonds, provided that such bonds are in their fixed rate term as of the Index Determination Date (as defined below)) or zero percent coupon. The Index considers investment grade securities to be rated Baa3/BBB-/BBB- or higher, using the middle rating of Moody's Investors Service, Inc., Fitch Ratings, Inc., or S&P Global Ratings. If only two of the three agencies rate the security, then the more conservative (lower) rating will be used to determine Index eligibility. If only one of the agencies rates the security, then that rating will be used. In addition, in order to be included in the Index, bonds must have both bid and offer price Composite+^TM ("CP+") valuations. CP+ is the Index Provider's (defined below) proprietary algorithmic pricing engine. CP+ analyzes industry and proprietary trading and liquidity data to provide an indication of the bid price and offer price valuations of a bond. If the CP+ pricing algorithm does not have access to enough liquidity inputs for a bond, it will not generate bid and offer price valuations and the bond will not be eligible for inclusion in the Index. Bonds are also screened based on liquidity as measured by their Relative Liquidity Score ("RLS"). RLS is the Index Provider's proprietary methodology that analyzes industry and proprietary trading data to score a bond's liquidity relative to bonds identified by the Index Provider as having similar risk and return characteristics. A bond's RLS ranges from 1 to 10, with 10 being the most liquid, and only bonds with an RLS of 7 or higher are eligible for inclusion in the Index.

Bonds that remain eligible for inclusion in the Index after applying the screens referred to above are then ranked by par value face amount from highest to lowest. For bonds with the same par value face amount, ranking is based on the following in order of priority: bonds with higher RLS, earlier issue date, and tighter CP+ bid/offer spread. After applying such ranking, the 400 highest-ranked bonds that comply with the following limitations are selected for inclusion in the Index and weighted by market value: (1) any single issuer is limited to 4% of the weight of the Index and (2) to the extent a sector's weight in the MarketAxess U.S. Investment Grade Broad Corporate Bond Index (the "Broad Market Index") is 5% or greater, a sector's weight in the Index is limited to 2.5% above such sector's weight in the Broad Market Index. The Index is rebalanced and reconstituted monthly after the close of business on the last business day of the month (the "Index Rebalance Date") based on determinations made on the fourth to last

business day preceding the Index Rebalance Date (the "Index Determination Date"). Securities eligible for inclusion in the Index include senior and subordinated debt, callable and puttable bonds, Rule 144A securities and Regulation S securities. As of April 30, 2022, a significant portion of the Index comprised companies in the financial sector, although this may change from time to time. As of April 30, 2022, there were 400 securities in the Index.

The Index is sponsored by MarketAxess Technologies Inc. (the "Index Provider"), which is not affiliated with the Fund or the Adviser. The Index Provider determines the composition of the Index, relative weightings of the securities in the Index and publishes information regarding the market value of the Index.

Principal Risks of Investing in the Fund

As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments.

Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets; the risk of low rates of return due to reinvestment of securities during periods of falling interest rates or repayment by issuers with higher coupon or interest rates; and/or the risk of low income due to falling interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. The current historically low interest rate environment heightens the risks associated with rising interest rates. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities.

Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Financial Sector Risk: Financial services companies are subject to extensive governmental regulation, which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.

Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates.

Indexing Strategy/Index Tracking Risk: The Fund is managed with an indexing investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of the Index or of the actual securities comprising the Index. This differs from an actively-managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund's performance may be less favorable than that of a portfolio managed using an active investment strategy. The structure and composition of the Index will affect the performance, volatility, and risk of the Index and, consequently, the performance, volatility, and risk of the Fund. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. When there are changes made to the component securities of the Index and the Fund in turn makes similar changes to its portfolio, any transaction costs and market exposure arising from such portfolio changes will be borne directly by the Fund and its shareholders. The Fund may recognize gains as a result of rebalancing or reconstituting its securities holdings to reflect changes in the securities included in the Index. The Fund also may be required to distribute any such gains to its shareholders to avoid adverse federal income tax consequences. While the Adviser seeks to track the performance of the Index (i.e., achieve a high degree of correlation with the Index), the Fund's return may not match the return of the Index. The Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities. In addition, the Fund may not be fully invested at times, generally as a result of cash flows into or out of the Fund or reserves of cash held by the Fund to meet redemptions. The Adviser may attempt to track the Index return by investing in fewer than all of the securities in the Index, or in some securities not included in the Index, potentially increasing the risk of divergence between the Fund's return and that of the Index.

Less Experienced Index Provider Risk: The Index was created by and is owned and maintained by the Index Provider. The Index Provider has a limited history of experience as an index provider, which may create additional risks for investing in the Fund. There is no assurance that Index data, Index computations or Index construction will be free from error, or that any such errors will be identified and corrected in a timely manner or at all.

Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. If the liquidity of the Fund's holdings deteriorates, it may lead to differences between the market price of Fund Shares and the net asset value of Fund Shares, and could result in the Fund Shares being less liquid. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector.

New Fund Risk: The Fund is new and there is no assurance that the Fund will grow quickly. When the Fund's size is small, the Fund may experience low trading volume, which could lead to wider bid/ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange. Any resulting liquidation of the Fund could cause elevated transaction costs for the Fund and negative tax consequences for its shareholders.

Non-U.S. Securities Risk: Non-U.S. securities are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Certain countries have recently experienced (or currently are expected to experience) negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity.

Restricted Securities Risk: The Fund may hold securities that have not been registered for sale to the public under the U.S. federal securities laws. There can be no assurance that a trading market will exist at any time for any particular restricted security. Limitations on the resale of these securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. The Fund may have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility.

Subordinated Debt Risk: The Fund may invest in debt securities that are subordinated to more senior securities of the issuer. Holders of debt securities that are subordinated or "junior" to more senior securities are entitled to payment after holders of more senior securities. Subordinated debt securities are more likely to suffer a credit loss than non-subordinated securities of the same issuer, may be disproportionately affected by a default, downgrade or perceived decline in creditworthiness, and may take longer to recover interest or principal.

Swaps Risk: A swap is a two-party contract that generally obligates the parties to exchange payments based on a specified reference security, basket of securities, security index or index component. Swaps can involve greater risks than direct investment in securities because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty's defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Valuation Risk: Some portfolio holdings, potentially a large portion of the Fund's investment portfolio, may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including "fair valued" securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

Zero-Coupon Bond Risk: Zero-coupon bonds usually trade at a deep discount from their face or par values and are subject to greater market value fluctuations from changing interest rates than debt obligations of comparable maturities that make current distributions of interest.

Fund Performance

The Fund had not commenced operations as of the date of this Prospectus. Once the Fund has completed a full calendar year of operations, a bar chart and table will be included that will provide some indication of the risks of investing in the Fund by showing the variability of the Fund's returns based on net assets and comparing the Fund's performance to the Index.

Purchase and Sale Information

The Fund will issue (or redeem) Fund Shares to certain institutional investors (typically market makers or other broker-dealers) only in large blocks of Fund Shares known as "Creation Units." Creation Unit transactions are conducted in exchange for the deposit or delivery of a designated portfolio of in-kind securities and/or cash.

Individual Fund Shares may only be purchased and sold on the NYSE Arca, Inc. (the "Exchange"), other national securities exchanges, electronic crossing networks and other alternative trading systems through your broker-dealer at market prices. Because Fund Shares trade at market prices rather than at net asset value ("NAV"), Fund Shares may trade at a price greater than

State Street Global Advisors

5 of 6

NAV (premium) or less than NAV (discount). When buying or selling Fund Shares in the secondary market, you may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Fund Shares (bid) and the lowest price a seller is willing to accept for Fund Shares (ask) (the "bid-ask spread"). Recent information regarding the Fund's NAV, market price, premiums and discounts, and bid-ask spreads is available at https://www.ssga.com/spdrs.

Tax Information

The Fund's distributions are expected to be taxed as ordinary income and/or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or individual retirement account. Any withdrawals made from a tax-advantaged arrangement may be taxable to you.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Fund Shares through a broker-dealer or other financial intermediary (such as a bank), the Adviser or its affiliates may pay the financial intermediary for certain activities related to the Fund, including educational training programs, conferences, the development of technology platforms and reporting systems, or other services related to the sale or promotion of the Fund. 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.
