Investment Objective
Fidelity® Short-Term Bond Fund seeks to obtain a high level of current income consistent with preservation of capital.
Fee Table
The following table describes the fees and expenses that may be incurred when you buy, hold, and sell shares of the fund's ETF Class. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

[A Based on estimated amounts for the current fiscal year.]
[B Fidelity Management & Research Company LLC (FMR) has contractually agreed to reimburse ETF Class shares of the fund to the extent that total operating expenses (excluding interest, certain taxes, fees and expenses of Independent Trustees, proxy and shareholder meeting expenses, extraordinary expenses, and acquired fund fees and expenses (including fees and expenses associated with a wholly owned subsidiary), if any, as well as non-operating expenses such as brokerage commissions and fees and expenses associated with the fund's securities lending program, if applicable), as a percentage of its average net assets, exceed [__]% (the Expense Cap). If at any time during the current fiscal year expenses for ETF Class shares of the fund fall below the Expense Cap, FMR reserves the right to recoup through the end of the fiscal year any expenses that were reimbursed during the current fiscal year up to, but not in excess of, the Expense Cap. This arrangement will remain in effect through [______]. FMR may not terminate this arrangement before the expiration date without the approval of the Board of Trustees and may extend it in its discretion after that date.]
This example helps compare the cost of investing in the fund's ETF Class with the cost of investing in other funds or classes.
Let's say, hypothetically, that the annual return for ETF Class shares of the fund is 5% and that the fees and the annual operating expenses for shares of the fund's ETF Class are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your ETF Class shares at the end of each time period indicated:

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 operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 59% of the average value of its portfolio.
Principal Investment Strategies
Debt securities are used by issuers to borrow money. The issuer usually pays a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security. Debt securities include corporate bonds, government securities (including Treasury securities), repurchase agreements, money market securities, mortgage and other asset-backed securities, loans and loan participations, and other securities, such as hybrids and synthetic securities, believed to have debt-like characteristics (e.g., securities classified as Tier 2 Regulatory capital, securities that rank above share capital in an insolvency waterfall, securities with maturity dates and non-cancellable interest payment structures). 
Investment grade securities in which the fund invests include securities or issuers rated at least BBB- or its equivalent by at least one nationally recognized statistical ratings organization (NRSRO), or, if unrated, determined by the Adviser to be of comparable quality.
A repurchase agreement is an agreement to buy a security at one price and a simultaneous agreement to sell it back at an agreed-upon price.
Derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives.
Principal Investment Risks
Interest rate increases can cause the price of a debt security to decrease.
Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.
The ability of an issuer of a debt security to repay principal prior to a security's maturity can cause greater price volatility if interest rates change.
The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.
A decline in the credit quality of an issuer or a provider of credit support (such as guarantees) or a maturity-shortening structure (such as demand and put features) for a security can cause the price of a security to decrease.
The net asset value per share (NAV) of the fund's ETF Class will generally fluctuate with changes in the market value of the fund's holdings. The fund's ETF Class shares can be bought and sold in the secondary market at market prices. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for the fund's ETF Class shares may result in the fund's ETF Class shares trading significantly above (at a premium) or below (at a discount) to NAV.
Given the nature of the relevant markets for certain of the fund's securities, the fund's ETF Class shares may trade at a larger premium or discount to the NAV than shares of other ETFs.
In addition, in stressed market conditions or periods of market disruption or volatility, the market for the fund's ETF Class shares may become less liquid in response to deteriorating liquidity in the markets for the fund's underlying portfolio holdings.
There can be no assurance that an active trading market will be maintained. Market makers and Authorized Participants are not obligated to make a market in the fund's ETF Class shares or to submit purchase and redemption orders for creation units. Decisions by market makers or Authorized Participants to reduce their role with respect to market making or creation and redemption activities during times of market stress, or a decline in the number of Authorized Participants due to decisions to exit the business, bankruptcy, or other factors, could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying value of the fund's portfolio securities and the market price of the fund's ETF Class shares. In addition, trading may be halted, for example, due to market conditions.
Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly.
The fund may effect some or all creations and redemptions of its ETF Class shares using cash rather than in-kind securities. As a result, an investment in the fund may be less tax-efficient than an investment in a fund that effects ETF share class redemptions entirely in-kind.
An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You could lose money by investing in the fund.
Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate.
Performance
The following information is intended to help you understand the risks of investing in the fund.
The ETF Class shares are a new class of shares for which performance information is not available, and therefore, for periods prior to the inception of the ETF Class shares, the bar chart and table show performance information for the Fidelity® Short-Term Bond Fund shares of the fund, a mutual fund class of shares of the fund not offered in this Prospectus. Returns of the ETF Class shares of the fund may vary from the returns of the Fidelity® Short-Term Bond Fund shares due to differences in expenses.
The information illustrates the changes in the performance of Fidelity® Short-Term Bond Fund, a class of shares of the fund, from year to year and compares the performance of this class to the performance of a securities market index and an additional index over various periods of time. The additional index has characteristics relevant to the fund's investment strategies. Index descriptions appear in the "Additional Index Information" section of the prospectus. Past performance (before and after taxes) is not an indication of future performance.
Visit www.fidelity.com for more recent performance information for Fidelity® Short-Term Bond Fund, a class of shares of the fund.
Performance history will be available at www.fidelity.com for ETF Class after ETF Class has been in operation for one calendar year.

Investment Adviser
Fidelity Management & Research Company LLC (FMR) (the Adviser) is the fund's manager. Other investment advisers serve as sub-advisers for the fund.
Portfolio Manager(s)
Robert Galusza (Co-Portfolio Manager) has managed the fund since 2007.
Julian Potenza (Co-Portfolio Manager) has managed the fund since 2017.
Effective on or about March 31, 2026, Julian Potenza will no longer serve as Co-Portfolio Manager of the fund.
David DeBiase (Co-Portfolio Manager) has managed the fund since 2019.
John Mistovich (Co-Portfolio Manager) has managed the fund since 2024.
Purchase and Sale of Shares
ETF Class shares of the fund are listed and traded on an exchange, and individual ETF Class shares may only be bought and sold in the secondary market through a broker or dealer at market price and are not individually redeemable. These transactions, which do not involve the fund, are made at market prices that may vary throughout the day, rather than at NAV. ETF Class shares of the fund may trade at a price greater than the ETF Class's NAV (premium) or less than the ETF Class's NAV (discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase ETF Class shares (bid) and the lowest price a seller is willing to accept for such shares (ask) when buying or selling ETF Class shares in the secondary market (the "bid-ask spread"). Recent information, including information regarding the ETF Class's NAV, market price, premiums and discounts, and bid-ask spread, is available at www.fidelity.com.
The fund offers one or more mutual fund classes described in a separate prospectus in addition to ETF Class shares. A shareholder holding a mutual fund class of the fund may convert those shares to ETF Class shares issued by the fund to the extent supported by the shareholder's financial intermediary. Shareholders should contact their financial intermediary to determine the eligibility of their account for such a conversion. ETF Class shares, whether acquired through a conversion or purchased on the secondary market, cannot be converted to mutual fund class shares of the fund or exchanged for mutual fund class shares or ETF Class shares of another fund. See "Shareholder Information -- Conversions" below for additional information.
Tax Information
Distributions you receive from the fund are subject to federal income tax and generally will be taxed as ordinary income or capital gains, and may also be subject to state or local taxes, unless you are investing through a tax-advantaged retirement account (in which case you may be taxed later, upon withdrawal of your investment from such account).
Payments to Broker-Dealers and Other Financial Intermediaries
The fund, the Adviser, Fidelity Distributors Company LLC (FDC), and/or their affiliates may pay intermediaries, which may include banks, broker-dealers, retirement plan sponsors, administrators, or service-providers (who may be affiliated with the Adviser or FDC), for the sale of fund shares and related services. These payments may create a conflict of interest by influencing your intermediary and your investment professional to recommend the fund over another investment. Ask your investment professional or visit your intermediary's web site for more information.
 
Fund Basics
Investment Details
Investment Objective
Fidelity® Short-Term Bond Fund seeks to obtain a high level of current income consistent with preservation of capital.
Principal Investment Strategies
The Adviser normally invests at least 80% of the fund's assets in investment-grade debt securities of all types and repurchase agreements for those securities.
Debt securities are used by issuers to borrow money. The issuer usually pays a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security. Debt securities include corporate bonds, government securities (including Treasury securities), repurchase agreements, money market securities, mortgage and other asset-backed securities, loans and loan participations, and other securities, such as hybrids and synthetic securities, believed to have debt-like characteristics (e.g., securities classified as Tier 2 Regulatory capital, securities that rank above share capital in an insolvency waterfall, securities with maturity dates and non-cancellable interest payment structures).
Investment grade securities in which the fund invests include securities or issuers rated at least BBB- or its equivalent by at least one nationally recognized statistical ratings organization (NRSRO), or, if unrated, determined by the Adviser to be of comparable quality.
A repurchase agreement is an agreement to buy a security at one price and a simultaneous agreement to sell it back at an agreed-upon price.
Derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives.
The Adviser uses the Bloomberg U.S. 1-3 Year Government/Credit Bond Index as a guide in structuring the fund and selecting its investments. The Adviser manages the fund to have similar overall interest rate risk to the index.
The Adviser considers other factors when selecting the fund's investments, including the credit quality of the issuer, security-specific features, current valuation relative to alternatives in the market, short-term trading opportunities resulting from market inefficiencies, and potential future valuation. In managing the fund's exposure to various risks, including interest rate risk, the Adviser considers, among other things, the market's overall risk characteristics, the market's current pricing of those risks, and internal views of potential future market conditions.
In addition, the fund normally maintains a dollar-weighted average maturity of three years or less. As of August 31, 2025, the fund's dollar-weighted average maturity was approximately 2 years and the index's dollar-weighted average maturity was approximately 2 years. In determining a security's maturity for purposes of calculating the fund's average maturity, an estimate of the average time for its principal to be paid may be used. This can be substantially shorter than its stated maturity.
The Adviser allocates the fund's assets among different market sectors (for example, corporate, asset-backed, or government securities) and different maturities based on its view of the relative value of each sector or maturity.
The Adviser may invest the fund's assets in securities of foreign issuers in addition to securities of domestic issuers.
The Adviser may engage in transactions that have a leveraging effect on the fund, including investments in derivatives, regardless of whether the fund may own the asset, instrument, or components of the index underlying the derivative, and forward-settling securities. The Adviser may invest a significant portion of the fund's assets in these types of investments. If the fund invests a significant portion of its assets in derivatives, its investment exposure could far exceed the value of its portfolio securities and its investment performance could be primarily dependent upon securities it does not own. The fund's derivative investments may include interest rate swaps, total return swaps, credit default swaps, options (including options on futures and swaps), and futures contracts (both long and short positions) on securities, other instruments, and indexes. Depending on the Adviser's outlook and market conditions, the Adviser may engage in these transactions to increase or decrease the fund's exposure to changing security prices, interest rates, credit qualities, or other factors that affect security values, or to gain or reduce exposure to an asset, instrument, or index.
To earn additional income for the fund, the Adviser may use a trading strategy that involves selling (or buying) mortgage securities and simultaneously agreeing to purchase (or sell) mortgage securities on a later date at a set price. This trading strategy may increase interest rate exposure and result in an increased portfolio turnover rate which increases transaction costs and may increase taxable gains.
The Adviser uses Central funds to help invest the fund's assets. Central funds are specialized investment vehicles designed to be used by Fidelity® funds. Fidelity uses them to invest in particular security types or investment disciplines; for example, rather than buy bonds directly, the fund may invest in a Central fund that buys bonds. Fidelity generally does not charge any management fees for Central funds.
If the Adviser's strategies do not work as intended, the fund may not achieve its objective.
Description of Principal Security Types
In addition to the security types discussed above, the following describes the types of securities in which the fund invests or may invest principally:
Derivatives are investments whose values are tied to an underlying asset, instrument, currency, or index. Derivatives include futures, options, forwards, and swaps, such as interest rate swaps (exchanging a floating rate for a fixed rate), total return swaps (exchanging a floating rate for the total return of an index, security, or other instrument or investment) and credit default swaps (buying or selling credit default protection).
Forward-settling securities involve a commitment to purchase or sell specific securities when issued, or at a predetermined price or yield. When a fund does not already own or have the right to obtain securities equivalent in kind and amount, a commitment to sell securities is equivalent to a short sale. Payment and delivery take place after the customary settlement period.
Central funds are special types of investment vehicles created by Fidelity for use by Fidelity® funds and other advisory clients. Central funds incur certain costs related to their investment activity (such as custodial fees and expenses), but generally do not pay management fees. The investment results of the portions of the fund's assets invested in the Central funds will be based upon the investment results of those funds.
Principal Investment Risks
Many factors affect the fund's performance. Developments that disrupt global economies and financial markets, such as public health emergencies, military conflicts, terrorism, government restrictions, political changes, and environmental disasters, may significantly affect a fund's investment performance.
The ETF Class's NAV and yield change daily based on changes in market conditions and interest rates and in response to other economic, political, or financial developments. The fund's reaction to these developments will be affected by the types and maturities of securities in which the fund invests, the financial condition, industry and economic sector, and geographic location of an issuer, and the fund's level of investment in the securities of that issuer. When your shares are sold they may be worth more or less than what you paid for them, which means that you could lose money by investing in the fund.
Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate.
The following factors can significantly affect the fund's performance:
Interest Rate Changes. Debt securities, including money market securities, have varying levels of sensitivity to changes in interest rates. In general, the price of a debt security can fall when interest rates rise and can rise when interest rates fall. Securities with longer maturities and certain types of securities, such as mortgage securities and the securities of issuers in the financial services sector, can be more sensitive to interest rate changes, meaning the longer the maturity of a security, the greater the impact a change in interest rates could have on the security's price. Short-term and long-term interest rates do not necessarily move in the same amount or the same direction. Short-term securities tend to react to changes in short-term interest rates, and long-term securities tend to react to changes in long-term interest rates. Securities with floating interest rates can be less sensitive to interest rate changes, but may decline in value if their interest rates do not rise as much as interest rates in general. Securities whose payment at maturity is based on the movement of all or part of an index and inflation-protected debt securities may react differently from other types of debt securities. In market environments where interest rates are rising, issuers may be less willing or able to make principal and/or interest payments on securities when due.
Foreign Exposure. Foreign securities and securities issued by U.S. entities with substantial foreign operations can involve additional risks relating to political, economic, or regulatory conditions in foreign countries. These risks include fluctuations in foreign exchange rates; withholding or other taxes; trading, settlement, custodial, and other operational risks; and the less stringent investor protection and disclosure standards of some foreign markets. All of these factors can make foreign investments more volatile and potentially less liquid than U.S. investments. In addition, foreign markets can perform differently from the U.S. market.
Global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers or providers in, or foreign exchange rates with, a different country or region.
Prepayment. Many types of debt securities, including mortgage securities, are subject to prepayment risk. Prepayment risk occurs when the issuer of a security can repay principal prior to the security's maturity. Securities subject to prepayment can offer less potential for gains during a declining interest rate environment and similar or greater potential for loss in a rising interest rate environment. In addition, the potential impact of prepayment features on the price of a debt security can be difficult to predict and result in greater volatility.
Issuer-Specific Changes. Changes in the financial condition of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's credit quality or value. Entities providing credit support (such as guarantees) or a maturity-shortening structure (such as demand and put features) also can be affected by these types of changes, and if the structure of a security fails to function as intended, the security could decline in value. Lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds) tend to be more sensitive to these changes than higher quality debt securities.
Fluctuation of Net Asset Value and Share Price. The NAV of the fund's ETF Class shares will generally fluctuate with changes in the market value of the fund's holdings. The fund's ETF Class shares are listed on an exchange and can be bought and sold in the secondary market at market prices. The market prices of shares will fluctuate in accordance with changes in NAV and supply and demand on the listing exchange. Although an ETF Class share's market price is expected to approximate its NAV, it is possible that the market price and NAV will vary significantly. As a result, you may sustain losses if you pay more than the ETF Class shares' NAV when you purchase ETF Class shares, or receive less than the ETF Class shares' NAV when you sell ETF Class shares, in the secondary market. During periods of disruptions to creations and redemptions, the existence of extreme market volatility, or lack of an active trading market for the fund's ETF Class shares, the market price of the fund's ETF Class shares is more likely to differ significantly from the ETF Class's NAV. During such periods, you may be unable to sell your shares or may incur significant losses if you sell your ETF Class shares. There are various methods by which investors can purchase and sell ETF Class shares and various orders that may be placed. Investors should consult their financial intermediary before purchasing or selling ETF Class shares of a fund. Disruptions at market makers, Authorized Participants or market participants may also result in significant differences between the market price of the fund's ETF Class shares and the ETF Class's NAV. In addition, in stressed market conditions or periods of market disruption or volatility, the market for shares may become less liquid in response to deteriorating liquidity in the markets for the fund's underlying portfolio holdings.
The market price of ETF Class shares during the trading day, like the price of any exchange-traded security, includes a bid-ask spread charged by the exchange specialist, market makers, or other participants that trade the particular security. In times of severe market disruption or volatility, the bid-ask spread can increase significantly. At those times, ETF Class shares are most likely to be traded at a discount to NAV, and the discount is likely to be greatest when the price of ETF Class shares is falling fastest, which may be the time that you most want to sell your ETF Class shares. Securities held by a fund may be traded in markets that close at a different time than the listing exchange. During the time when the listing exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads and the resulting premium or discount to the ETF Class's NAV may widen. The Adviser expects that, under normal market conditions, large discounts or premiums to NAV will not be sustained in the long term because of arbitrage opportunities.
Trading Issues. Although ETF Class shares are listed on an exchange, there can be no assurance that an active trading market or requirements to remain listed will be met or maintained. Only an Authorized Participant may engage in creation or redemption transactions directly with the fund. The fund has a limited number of intermediaries that act as Authorized Participants. There are no obligations of market makers to make a market in the fund's ETF Class shares or of Authorized Participants to submit purchase or redemption orders for Creation Units. Decisions by market makers or Authorized Participants to reduce their role with respect to market making or creation and redemption activities during times of market stress, or a decline in the number of Authorized Participants due to decisions to exit the business, bankruptcy, or other factors, could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying value of the fund's portfolio securities and the market price of the fund's ETF Class shares. To the extent no other Authorized Participants are able to step forward to create or redeem, ETF Class shares may trade at a discount to NAV and possibly face delisting. In addition, trading of ETF Class shares in the secondary market may be halted, for example, due to activation of marketwide "circuit breakers." If trading halts or an unanticipated early closing of the listing exchange occurs, a shareholder may be unable to purchase or sell ETF Class shares of the fund. FDC, the distributor of the fund's shares, does not maintain a secondary market in the ETF Class shares.
If a fund's ETF Class shares are delisted from the listing exchange, the Adviser may seek to list the ETF Class shares on another market, merge the fund's ETF Class with another class of the fund, or liquidate the fund's ETF Class shares at NAV.
ETF Class shares of a fund, similar to shares of other issuers listed on a stock exchange, may be sold short and are therefore subject to the risk of increased volatility and price decreases associated with being sold short.
Leverage Risk. Derivatives, forward-settling securities, and short sale transactions involve leverage because they can provide investment exposure in an amount exceeding the initial investment. Leverage can magnify investment risks and cause losses to be realized more quickly. A small change in the underlying asset, instrument, or index can lead to a significant loss. Forward-settling securities and short sale transactions also involve the risk that a security will not be issued, delivered, available for purchase, or paid for when anticipated. An increase in the market price of securities sold short will result in a loss. Government legislation or regulation could affect the use of these transactions and could limit a fund's ability to pursue its investment strategies.
Cash Transactions Risk. The fund may effect some or all creations and redemptions of ETF Class shares using cash rather than in-kind securities. Therefore, it may be required to sell portfolio securities and recognize gains on such sales that the fund might not have recognized if it were to distribute portfolio securities in-kind. As a result, an investment in the fund may be less tax-efficient than an investment in a fund that effects ETF share class redemptions entirely in-kind. The use of cash creations and redemptions may also cause the fund's ETF Class shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the ETF Class's NAV. Furthermore, cash creation and redemption transactions may result in certain brokerage, tax, foreign exchange, execution, price movement and other costs and expenses related to the execution of trades resulting from such transactions. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover these costs and expenses, the fund's performance could be negatively impacted.
In response to market, economic, political, or other conditions, a fund may temporarily use a different investment strategy for defensive purposes. If the fund does so, different factors could affect its performance and the fund may not achieve its investment objective.
Other Investment Strategies
In addition to the principal investment strategies discussed above, the Adviser may invest in collateralized loan obligations.
The Adviser may invest the fund's assets in lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds).

Shareholder Notice
The following is subject to change only upon 60 days' prior notice to shareholders:
Fidelity® Short-Term Bond Fund normally invests at least 80% of its assets in investment-grade debt securities of all types and repurchase agreements for those securities.
Valuing Shares
The fund is open for business each day that either the listing exchange or the New York Stock Exchange (NYSE) is open.
The ETF Class's NAV is the value of a single share. Fidelity normally calculates NAV as of the close of regular trading hours on the listing exchange or the NYSE, normally 4:00 p.m. Eastern time. The fund's assets normally are valued as of this time for the purpose of computing NAV. The prices at which creations and redemptions occur are based on the next calculation of NAV after a creation or redemption order is received in an acceptable form under the authorized participant agreement.
NAV is not calculated and the fund will not process purchase and redemption requests submitted on days when the fund is not open for business. The time at which shares are priced and until which purchase and redemption orders are accepted may be changed as permitted by the Securities and Exchange Commission (SEC).
ETF Class shares of the fund may be purchased through a broker in the secondary market by individual investors at market prices which may vary throughout the day and may differ from the ETF Class's NAV.
To the extent that the fund's assets are traded in other markets on days when the fund is not open for business, the value of the fund's assets may be affected on those days. In addition, trading in some of the fund's assets may not occur on days when the fund is open for business.
Shares of open-end funds in which the fund may invest (referred to as underlying funds) are valued at their respective NAVs. NAV is calculated using the values of any underlying funds in which it invests. Other assets are valued primarily on the basis of market quotations, official closing prices, or information furnished by a pricing service. Certain short-term securities are valued on the basis of amortized cost. If market quotations, official closing prices, or information furnished by a pricing service are not readily available or, in the Adviser's opinion, are deemed unreliable for a security, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. For example, if, in the Adviser's opinion, a security's value has been materially affected by events occurring before a fund's pricing time but after the close of the exchange or market on which the security is principally traded, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. Fair value pricing will be used for high yield debt securities when available pricing information is determined to be stale or for other reasons not to accurately reflect fair value.
Fair value pricing is based on subjective judgments and it is possible that the fair value of a security may differ materially from the value that would be realized if the security were sold.

General Information
Information on Fidelity
Fidelity Investments was established in 1946 to manage one of America's first mutual funds. Today, Fidelity is one of the world's largest providers of financial services.
In addition to its fund business, the company operates one of America's leading brokerage firms, Fidelity Brokerage Services LLC. Fidelity is also a leader in providing tax-advantaged retirement plans for individuals investing on their own or through their employer. 
The Depository Trust Company (DTC) is a limited trust company and securities depository that facilitates the clearance and settlement of trades for its participating banks and broker-dealers. DTC has executed an agreement with FDC, the fund's distributor.
Multi-Class ETF Fund Structure
The Adviser has obtained an exemptive order from the SEC that permits the fund to offer mutual fund share classes and an exchange-traded share class that operates as an ETF (a "Multi-Class ETF Fund"). Under this structure, the ETF Class shares are listed and traded on an exchange and are bought and sold at market prices, whereas shares of a mutual fund class are purchased and redeemed at the class's NAV next calculated after an order is received in proper form.
Due to the structural and operational differences of mutual funds and ETFs, shareholders of the mutual fund and ETF Class shares of a Multi-Class ETF Fund will have differing shareholder rights with respect to exchange and conversion privileges, how shares are purchased and redeemed, the timing of dividend declarations and payments, and the timing and ability to automatically reinvest dividends. For additional information regarding these differences, see "Purchase and Sale of Shares" in the Fund Summary and "Conversions" and "Dividends and Capital Gain Distributions" under "Shareholder Information" in this Prospectus and "Buying and Selling Information" in the Statement of Additional Information (SAI).
In addition, because all of the classes of a Multi-Class ETF Fund are based on the same portfolio, transactions through one class could generate portfolio transaction costs and tax consequences for shareholders in other classes. For example, shareholders of ETF Class shares of a Multi-Class ETF Fund have the potential to experience greater portfolio transaction costs and taxable capital gains distributions than shareholders of a standalone ETF as a result of purchases and redemptions by shareholders of mutual fund class shares, as well as costs due to the fund holding cash necessary to satisfy redemptions of the mutual fund class shares, which could negatively impact the ETF Class's performance. At the same time, shareholders of all classes of a Multi-Class ETF Fund may benefit from cost savings and economies of scale to the extent that the multiple classes draw additional assets to the Multi-Class ETF Fund.
A Multi-Class ETF Fund also is required to comply with additional requirements applicable to ETFs that do not normally apply to a mutual fund. For example, a Multi-Class ETF Fund is required to disclose its complete holdings daily, which has the potential to make the fund more susceptible to front running than a traditional mutual fund that provides more limited public disclosure of portfolio holdings. Also, unlike a traditional mutual fund, a Multi-Class ETF Fund may not have the same flexibility to close the fund to new purchases.
The use of this structure is subject to terms and conditions set forth in an SEC exemptive order that are designed to ensure that the Adviser and the fund's Board of Trustees focus on these potential issues on an initial and ongoing basis. The conditions include that the Board, and a majority of the Independent Trustees, approve (initially, and at least annually thereafter) the operation of a Multi-Class ETF Fund pursuant to a multiple-class plan, finding that the plan is in the best interests of each mutual fund class and the ETF Class individually, and in the best interests of the Multi-Class ETF Fund as a whole. The Adviser will prepare written reports to assist the Board's findings that contain information regarding, among other items, the potential and/or observed benefits and costs to each class individually and the fund as a whole due to the structure, the appropriateness of the fund's investment strategy for the structure, and the potential and/or observed material conflicts of interest between the classes and/or material negative consequences resulting from the structure.
Buying and Selling Shares in the Secondary Market
ETF Class shares of the fund are listed and traded on an exchange, and individual ETF Class shares may only be bought and sold in the secondary market through a broker. The fund does not impose any minimum investment for ETF Class shares purchased on an exchange. These transactions are made at market prices that may vary throughout the day and may be greater than the ETF Class's NAV (premium) or less than the ETF Class's NAV (discount). As a result, you may pay more than NAV when you purchase ETF Class shares, and receive less than NAV when you sell ETF Class shares, in the secondary market. If you buy or sell ETF Class shares in the secondary market, you will generally incur customary brokerage commissions and charges. Due to such commissions and charges, frequent trading may detract significantly from investment returns.
The fund's ETF Class shares are designed to offer investors an investment that can be bought and sold frequently in the secondary market in a way that is unlikely to negatively impact the fund, and such trading activity is critical to ensuring that the market price of ETF Class shares remains at or close to NAV. Accordingly, the Board of Trustees has not adopted policies and procedures designed to discourage excessive or short-term trading by these investors.
ETF Class shares can be purchased and redeemed directly from the fund at NAV only by Authorized Participants in large increments called "Creation Units." The fund accommodates frequent purchases and redemptions of Creation Units by Authorized Participants and does not place a limit on purchases or redemptions of Creation Units by these investors. The fund reserves the right, but does not have the obligation, to reject any purchase transaction at any time. In addition, the fund reserves the right to impose restrictions on disruptive, excessive, or short-term trading.
Conversions
A shareholder holding a mutual fund class of the fund may convert those shares to ETF Class shares issued by the same fund to the extent supported by the shareholder's financial intermediary. Shareholders should contact their financial intermediary to determine the eligibility of their account for such a conversion. ETF Class shares, whether acquired through a conversion or purchased on the secondary market, cannot be converted to mutual fund class shares of the same fund or exchanged for mutual fund class shares or ETF Class shares of another fund.
ETF Class shares must be held in a brokerage account. Prior to a conversion, shareholders that hold mutual fund class shares of the fund through its transfer agent, or in a brokerage account that only allows the shareholder to hold mutual fund shares, will need to independently designate an eligible brokerage account for holding the ETF Class shares. Shareholders that hold mutual fund class shares in a 401(k) plan or other employer-sponsored retirement or benefit plan generally may not convert those shares to ETF Class shares and should check with their plan sponsor or recordkeeper regarding eligibility.
A conversion of mutual fund class shares to ETF Class shares of the same fund will be processed at the relative NAVs of the respective share classes at the time of conversion. Since Depository Trust Company (DTC) (or its nominee) serves as the record owner of, and holds legal title to, the ETF Class shares of a fund and does not support the distribution and transfer of fractional ETF Class shares, a shareholder may be unable to convert a portion of their mutual fund class shares into ETF Class shares. Shareholders should work with their financial intermediary to determine options for redeeming any remaining mutual fund class shares. To the extent the automatic redemption of remaining mutual fund class shares is supported by a shareholder's financial intermediary, the submission of a request to convert mutual fund class shares to ETF Class shares may be deemed a submission of a redemption request for such remaining shares. To the extent the automatic redemption of remaining mutual fund class shares is not supported by a shareholder's financial intermediary, shareholders may need to initiate a subsequent redemption request of such remaining shares.
For example, if a shareholder's mutual fund class shares were equal to 10.50 ETF Class shares based on the relative NAVs of the classes, DTC's system would only account for the transfer of 10 whole ETF Class shares. If a shareholder's financial intermediary does not accommodate the ownership of fractional shares of ETFs, a portion of their mutual fund class shares investment equal to 0.50 fractional ETF Class shares would remain in the mutual fund share class, and redemption of this residual amount may require additional action through their financial intermediary. The redemption of remaining mutual fund class shares could be processed automatically if the shareholder's financial intermediary can support the automatic redemption of such shares, otherwise a shareholder may be required to redeem the portion of their mutual fund class shares investment equal to 0.50 fractional ETF Class shares. The redemption of such shares would be a taxable event. Shareholders will not otherwise recognize a taxable gain (or loss) on the conversion of mutual fund class shares of the fund into ETF Class shares of the fund.
Shareholders should contact their financial intermediary to determine whether a conversion or the redemption of any remaining mutual fund class shares may be subject to fees and expenses. The fund does not impose a transaction fee on conversions but reserves the right to impose a fee or to limit, temporarily suspend, or terminate the conversion privilege in the future.
Mutual fund class shareholders who invest directly through Fidelity should contact Fidelity at 1-800-FIDELITY (Retail class) and 1-877-208-0098 (Advisor classes) to request a conversion. Mutual fund class shareholders who invest through a third-party financial intermediary should contact that financial intermediary for information regarding conversions. Conversions may be available only during certain time periods. The availability and length of the conversion process will depend on a shareholder's financial intermediary, but may take several days from the date the request is accepted. Shareholders will remain fully invested in their mutual fund class shares until the conversion process is complete.
Precautionary Notes
For example, you may be deemed a statutory underwriter if you purchase Creation Units from the fund, break them down into individual fund shares, and sell such shares directly to customers, or if you choose to couple the creation of a supply of new ETF Class shares with an active selling effort involving solicitation of secondary market demand for ETF Class shares. A determination of whether a person is an underwriter for purposes of the Securities Act depends upon all of the facts and circumstances pertaining to that person's activities, and the examples mentioned here should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.
Dealers who are not "underwriters" but are participating in a distribution (as opposed to engaging in ordinary secondary market transactions), and thus dealing with ETF Class shares as part of an "unsold allotment" within the meaning of Section 4(a)(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act.
This is because the prospectus delivery exemption in Section 4(a)(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, you should note that dealers who are not underwriters but are participating in a distribution (as opposed to engaging in ordinary secondary market transactions) and thus dealing with the ETF Class shares that are part of an overallotment within the meaning of Section 4(a)(3)(A) of the Securities Act would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act. Firms that incur a prospectus-delivery obligation with respect to ETF Class shares of the fund are reminded that, under Rule 153 under the Securities Act, a prospectus delivery obligation under Section 5(b)(2) of the Securities Act owed to an exchange member in connection with a sale on an exchange is satisfied by the fact that the prospectus is available at the exchange upon request. The prospectus delivery mechanism provided in Rule 153 is only available with respect to transactions on an exchange. Certain affiliates of the fund may purchase and resell ETF Class shares pursuant to this prospectus.
Costs Associated with Creations and Redemptions 
The fund may impose a creation transaction fee and a redemption transaction fee to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units of ETF Class shares. Information about the procedures regarding creation and redemption of Creation Units and the applicable transaction fees is included in the SAI.
Dividends and Capital Gain Distributions
The fund earns interest, dividends, and other income from its investments, and distributes this income (less expenses) to shareholders as dividends. The fund also realizes capital gains from its investments, and distributes these gains (less any losses) as capital gain distributions. If you purchased your shares in the secondary market, your broker is responsible for distributing the income and capital gain distributions to you.
To reinvest dividend and capital gains distributions, you must hold your ETF Class shares at a broker that offers a reinvestment service. If a reinvestment service is available, distributions of income and capital gains can be automatically reinvested in additional ETF Class shares. If a reinvestment service is not available, you will receive your distributions in cash, and your distributions will not be reinvested. To determine whether a reinvestment service is available and whether there is a commission or other charge for using this service, consult your broker.
The ETF Class normally declares dividends and pays capital gain distributions per the tables below:
Fund Name
  
Dividends Paid
Fidelity® Short-Term Bond Fund - ETF Class
  
Declare and pay monthly
Fund Name
  
Capital Gains Paid
Fidelity® Short-Term Bond Fund - ETF Class
  
October, December
Given differences in timing of payment and reinvestment for mutual fund and ETF Class shares, an ETF Class reinvestment would potentially be made at a different time and at a different price than a mutual fund class reinvestment. Any taxable distributions by the fund, whether reinvested in additional ETF Class shares or paid in cash, generally will be taxable to shareholders who are subject to tax. Any such additional ETF Class shares will have a tax basis equal to the amount reinvested for federal tax purposes. The additional ETF Class shares will have a new holding period commencing on the day following the reinvestment day.
The cash payment date for mutual fund class distributions is typically one or more business days before the cash payment date for ETF Class distributions. This timing difference is due to the fact that ETF Class shares are exchange-traded and, like all ETFs, require a multiple day delay between ex-dividend date and payment date whereas mutual funds do not. During any period between the payment of the distribution to mutual fund class shareholders and the payment of the distribution to ETF Class shareholders, the cash that the fund will eventually use to pay the distribution to ETF Class shareholders will not be invested outside of participation in cash sweep vehicles (including money market funds), custodial credit earning programs or interest-bearing accounts. Any return associated with those assets during that time is expected to be negligible and will go to the benefit of the entire fund (not just the ETF Class).
Tax Consequences
As with any investment, your investment in the fund could have tax consequences for you (for non-retirement accounts).
Taxes on Distributions
Distributions investors receive are subject to federal income tax, and may also be subject to state or local taxes.
For federal tax purposes, certain distributions, including dividends and distributions of short-term capital gains, are taxable to investors as ordinary income, while certain distributions, including distributions of long-term capital gains, are taxable to investors generally as capital gains. A percentage of certain distributions of dividends may qualify for taxation at long-term capital gains rates (provided certain holding period requirements are met). Because the fund's income is primarily derived from interest, dividends from the fund generally will not qualify for the long-term capital gains tax rates available to individuals.
The fund may effect creations and redemptions of ETF Class shares using cash rather than in-kind securities and generally expects to fund shareholder redemptions of its mutual fund class shares using cash, and as a result, may recognize more capital gains and be less tax-efficient than if in-kind securities were used. When the fund effects its ETF Class redemptions with cash rather than with in-kind securities and when it redeems its mutual fund class shares, the fund may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds, which involves transaction costs and may cause the fund to recognize gains that might not have been otherwise recognized or to recognize such gains sooner than otherwise. Losses from sales of immediately reacquired securities are subject to deferral, potentially indefinitely. The fund generally intends to distribute net annual gains, if any, to shareholders to comply with applicable tax rules, causing shareholders to be subject to tax on gains they would not otherwise be subject to or at an earlier date than if the fund effected ETF Class redemptions in-kind.
If investors buy shares when a fund has realized but not yet distributed income or capital gains, they will be "buying a dividend" by paying the full price for the shares and then receiving a portion of the price back in the form of a taxable distribution.
Any taxable distributions you receive from the fund will normally be taxable to you when you receive them; however, you will receive certain December distributions in January, but those distributions will be taxable as if you received them on December 31.
Taxes on Transactions
Purchases and sales of shares, as well as purchases and redemptions of Creation Units, may result in a capital gain or loss for federal tax purposes.

The Adviser pays FMR Investment Management (UK) Limited, Fidelity Management & Research (Hong Kong) Limited, and Fidelity Management & Research (Japan) Limited for providing sub-advisory services.
The basis for the Board of Trustees approving the management contract and sub-advisory agreements for the fund is available in the fund's Form N-CSRS report for the fiscal period ended February 28, 2026, [and will be included in the fund's [Form N-CSR/Form N-CSRS] report for the fiscal period ending [       ]].
From time to time, the Adviser or its affiliates may agree to reimburse or waive certain fund expenses while retaining the ability to be repaid if expenses fall below the specified limit prior to the end of the fiscal year.
Reimbursement or waiver arrangements can decrease expenses and boost performance.
Fund Distribution
The fund is composed of multiple classes of shares. All classes of the fund have a common investment objective and investment portfolio.
FDC distributes the fund's ETF Class shares.
Intermediaries may receive from the Adviser, FDC, and/or their affiliates compensation for providing recordkeeping and administrative services, as well as other retirement plan expenses, and compensation for services intended to result in the sale of fund shares.
These payments are described in more detail in this section and in the SAI.
Distribution and Service Plan(s)
While the fund's ETF Class will not make direct payments for distribution or shareholder support services, the fund has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act with respect to its ETF Class shares. The Plan recognizes that the Adviser may use its management fee revenues, as well as its past profits or its resources from any other source, to pay FDC for expenses incurred in connection with providing services intended to result in the sale of ETF Class shares of the fund and/or shareholder support services. The Adviser, directly or through FDC, may pay significant amounts to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for ETF Class shares of the fund.
If payments made by the Adviser to FDC or to intermediaries under the Distribution and Service Plan were considered to be paid out of the class's assets on an ongoing basis, they would increase the cost of your investment and might cost you more than paying other types of sales charges.
No dealer, sales representative, or any other person has been authorized to give any information or to make any representations, other than those contained in this prospectus and in the related SAI, in connection with the offer contained in this prospectus. If given or made, such other information or representations must not be relied upon as having been authorized by the fund or FDC. This prospectus and the related SAI do not constitute an offer by the fund or by FDC to sell shares of the fund to, or to buy shares of the fund from, any person to whom it is unlawful to make such offer.

Financial Highlights
 
Financial Highlights are intended to help you understand the financial history of fund shares for the past 5 years (or, if shorter, the period of operations). Certain information reflects financial results for a single share. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in shares (assuming reinvestment of all dividends and distributions). Because ETF Class shares have not commenced operations as of the end of the fund's fiscal year, financial highlights are not available. The annual information has been audited by [_____], independent registered public accounting firm, whose report, along with fund financial statements, is included in the annual report. Annual reports are available for free upon request.
