Market Recap

U.S. taxable investment-grade bonds notably declined for the 12 months ending August 31, 2022, as the U.S. Federal Reserve took aggressive action to stymie high inflation. The Bloomberg U.S. Aggregate Bond Index returned -11.52% for the period. In late 2021, bond yields rose when the Fed pivoted from an “easy” to a “tight” monetary stance. Its first step was to cease its purchases of bonds, part of a quantitative easing program to support the U.S. economy that began in 2008. In the first half of 2022, the Fed took more aggressive steps to thwart inflation. The central bank raised the federal funds target rate by 25 basis points (0.25%) in mid-March, 50 basis points in May and 75 basis points in June – its largest increase since 1994 – and said it was becoming more difficult to achieve a soft landing, in which the economy slows enough to bring down inflation while avoiding a recession. It also began to allow up to billions in Treasuries and mortgage bonds to mature every month without investing the proceeds. Despite another rate hike of 75 basis points in July, the index rose 2.44% for the month, only to reverse course (-2.83%) in August, when the Fed dashed hopes that it would soon “pivot” to an easier policy stance. For the full 12 months, shorter-term securities outpaced longer-term bonds, and higher-quality issues held up better than lower-rated bonds. Within the index, corporate bonds posted a return of -14.61%, trailing the -10.80% result for U.S. Treasuries. Outside the index, U.S. corporate high-yield bonds returned -10.43%, while U.S. Treasury Inflation-Protected Securities had a return of -5.98%.

Fidelity® Corporate Bond ETF

Performance (Unaudited)

The information provided in the tables below shows you the performance of Fidelity® Corporate Bond ETF, with comparisons over different time periods to the fund’s relevant benchmark. Seeing the returns over different time periods can help you assess the fund’s performance against relevant measurements. The performance information includes average annual total returns and is further explained in this section.*

The fund’s net asset value (NAV) performance is based on the NAV calculated each business day. It is calculated in accordance with the standard formula for valuing investment company shares as of the close of regular trading hours on NYSE Arca, Inc. (NYSE Arca) (normally 4:00 p.m. Eastern Time). The fund’s market price performance is based on the daily closing price of the shares of the fund on NYSE Arca. Since ETFs are bought and sold at prices set by the market – which can result in a premium or discount to NAV – the returns calculated using market price (market return) can differ from those calculated using NAV (NAV return). For information on these differences, please visit Fidelity.com or see the prospectus. The fund’s returns do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption or selling of fund shares. How a fund did yesterday is no guarantee of how it will do tomorrow.

Fidelity® Corporate Bond ETF

Management’s Discussion of Fund Performance

Comments from Co-Portfolio Managers Matthew Bartlett and Jay Small:

For the fiscal year ending August 31, 2022, the exchange-traded fund's (ETF) net asset value returned -15.30% and its market price returned -15.61%, trailing the -14.43% result of the benchmark, the Bloomberg U.S. Credit Bond Index. Within the context of a challenging period for riskier assets, security selection detracted versus the benchmark the past 12 months, whereas sector positioning had a roughly neutral impact on the fund's relative performance. Picks among investment-grade corporate bonds in the financials sector detracted the most. Within financials, choices among banks were the biggest negative, while selections among insurers and REITs (real estate investment trusts) detracted to a lesser degree. Overweight allocations to banks, REITs and finance companies also dampened relative performance. Within the industrials sector, picks among consumer-related issuers were the primary detractor, while choices among technology and communications companies were more modest dampeners. On the plus side, selection among and overweighted exposure to energy issuers aided relative performance. Outside of corporates, an out-of-benchmark stake in U.S. Treasuries, which we held for liquidity and risk-management purposes, was the largest positive contributor this period. This contribution was partially offset by underweighting other government-related categories, as these bonds outperformed credit in a declining market.

Fidelity® Investment Grade Bond ETF

Management’s Discussion of Fund Performance

Comments from Co-Portfolio Managers Jeffrey Moore and Michael Plage:

For the fiscal year ending August 31, 2022, the exchange-traded fund’s (ETF) net asset value returned -11.65%, compared with the -11.52% return for the benchmark Bloomberg U.S. Aggregate Bond Index. The ETF’s market price returned -11.70% the past 12 months. Relative to this index, the fund benefited from our positioning in U.S. Treasuries. Having sold all our shortest-dated Treasuries by the end of 2022, the fund's average duration (interest-rate sensitivity) was below that of the benchmark. This stance was helpful as rates rose this period. Another positive factor was the fund's notable underweighting in mortgage-backed securities (MBS). We limited our exposure here due to what we saw as MBS' poor risk/reward trade-off, and our reduced allocation lifted the fund's result, given these securities' weak performance over the past 12 months. In contrast, an overweighting in investment-grade corporate debt detracted, as credit spreads widened, sending yields higher and prices lower. We particularly saw underperformance from debt of high-quality bank issuers – which we favored for their generally defensive characteristics, such as their strong balance sheets and highly regulated nature, but that struggled amid the general underperformance of corporate bonds.

Fidelity® Investment Grade Securitized ETF

Management’s Discussion of Fund Performance

Comments from Co-Portfolio Managers Franco Castagliuolo and Sean Corcoran:

For the fiscal year ending August 31, 2022, the exchange-traded fund’s (ETF) net asset value returned -10.49%, lagging, net of fees, the -9.72% result of the benchmark, the Bloomberg U.S. Securitized Index. The ETF’s market price returned -10.36% the past 12 months. In managing the fund this period, we attempted to exploit market inefficiencies and identify attractively valued securities, in accordance with our longer-term strategy. The fund had more sensitivity to interest rates than the benchmark this period, as measured by its slightly longer duration. This positioning detracted from the fund’s performance versus the benchmark because interest rates rose more than we expected. The fund’s overweighting in 30-year mortgage-backed securities (MBS) issued by Fannie Mae and Freddie Mac, as well as its overweighting in Ginnie Mae securities, also hurt our relative result, given that that these securities lagged the benchmark. Exposure to non-agency residential MBS and non-agency commercial mortgage-backed securities (CMBS), categories that also underperformed this period, modestly detracted from relative performance as well. In contrast, underweighting MBS comprised of 15- and 20-year mortgages added meaningful value. Timely overweights in agency CMBS further boosted relative performance, as did exposure to asset-backed securities (ABS) comprised of auto and consumer loans.

Fidelity® Limited Term Bond ETF

Management’s Discussion of Fund Performance

Comments from Co-Portfolio Manager Rob Galusza:

For the fiscal year ending August 31, 2022, the exchange-traded fund’s (ETF) net asset value returned -6.38%, net of fees, trailing the -6.03% result of the benchmark Fidelity Limited Term Composite IndexSM. The ETF’s market price returned -6.47% the past 12 months. Overall, both sector allocation and security selection detracted from performance, relative to the benchmark. Specifically, the fund’s non-benchmark holdings in asset-backed securities and derivatives/futures hampered our result. The portfolio’s underweight position in U.S. Treasuries also modestly detracted from relative performance. Conversely, while corporate bonds struggled in general during the period, the fund’s corporate debt holdings added value versus the Composite index. Our positioning along the yield curve also helped, as did a notable underweighting in government agency debt. At period end, corporates made up about 62% of assets, roughly in line with the 64% average within the Composite index.

Management’s Discussion of Fund Performance

Comments from Co-Portfolio Managers Brandon Bettencourt and Richard Munclinger:

For the fiscal year ending August 31, 2022, the exchange traded fund’s (ETF) net asset value returned -1.53%, roughly in line with the -1.30% result of the benchmark, the Fidelity Low Duration Investment Grade Factor Index. The ETF’s market price returned -1.55% the past 12 months. The fund’s supplemental index, the Bloomberg U.S. Treasury Bill: 6-9 Months Index, returned -0.39%. Our results versus the benchmark met our goal of producing monthly returns, before expenses, that closely match the benchmark return. Given the large number of securities in the benchmark (roughly 370) and the significant cost and liquidity challenges associated with full replication of the index, we use “stratified sampling techniques” in constructing the portfolio. This approach involves defining and maintaining a subset of constituent securities that, in aggregate, mirrors the chief characteristics of the index – including maturity, duration, sector allocation, credit quality and other factors. Returns for all major categories of U.S. bonds were solidly negative for the year. Bond yields rose and prices fell as the U.S. Federal Reserve aggressively tightened monetary policy with interest rate hikes. The central bank raised the federal funds rate from zero at the start of the reporting period to a range of 2.25% to 2.50% by period end. Government bonds, including U.S. Treasuries, agency debentures and government agency-backed mortgage securities, outpaced riskier segments, like corporate-backed credit. Longer-term bonds suffered steeper declines than their shorter-term counterparts.

Note to shareholders: On August 31, 2021, the Bloomberg U.S. Treasury Bill: 6-9 Months Index was added as a supplemental index.

Management’s Discussion of Fund Performance

Comments from Co-Managers Ford O’Neil and Celso Munoz:

For the fiscal year ending August 31, 2022, the exchange traded fund’s (ETF) net asset value returned -11.32%, roughly in line, net of fees, with the -11.52% result of the benchmark, the Bloomberg U.S. Aggregate Bond Index. The ETF’s market price returned -11.43% the past 12 months. The fund had a shorter duration (less interest-rate sensitivity), which boosted relative performance as interest rates rose. Underweighting mortgage-backed securities also aided the fund’s relative return, as did non-index exposure to Treasury Inflation-Protected Securities (TIPS), which we owned early in the period. In contrast, allocations to “plus” sectors – including high-yield bonds, leveraged loans and emerging markets debt – detracted, given that these segments underperformed the benchmark in an environment that favored higher-quality sectors. Likewise, among investment-grade holdings, overweighting BBB-rated corporate bonds detracted, as these lower-quality securities lagged high-quality corporate bonds. Overweighting asset-backed securities, including collateralized loan obligations (CLOs), and commercial mortgage-backed securities, also hindered the relative result.

Note to shareholders: On October 1, 2022, Matthew Torchia assumed co-management responsibilities for the fund’s real estate high income sleeve. On October 1, 2022, Franco Castagliuolo assumed co-management responsibilities for the fund.

For the period ended August 31, 2022

1. Organization.

Fidelity Corporate Bond ETF, Fidelity Investment Grade Bond ETF, Fidelity Investment Grade Securitized ETF, Fidelity Limited Term Bond ETF, Fidelity Low Duration Bond Factor ETF and Fidelity Total Bond ETF (the Funds) are exchange-traded funds of Fidelity Merrimack Street Trust (the Trust) and are authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.

2. Investments in Fidelity Central Funds.

Funds may invest in Fidelity Central Funds, which are open-end investment companies generally available only to other investment companies and accounts managed by the investment adviser and its affiliates. The Schedule of Investments lists any Fidelity Central Funds held as an investment as of period end, but does not include the underlying holdings of each Fidelity Central Fund. An investing fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

Based on its investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the investing fund. These strategies are consistent with the investment objectives of the investing fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity Central Funds and thus a decline in the value of the investing fund.

Fidelity Central Fund	Investment Manager	Investment Objective	Investment Practices	Expense Ratio^(a)
Fidelity Money Market Central Funds	Fidelity Management & Research Company LLC (FMR)	Each fund seeks to obtain a high level of current income consistent with the preservation of capital and liquidity.	Short-term Investments	Less than .005%

^(a) Expenses expressed as a percentage of average net assets and are as of each underlying Central Fund’s most recent annual or semi-annual shareholder report.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds, which are not covered by the Report of Independent Registered Public Accounting Firm, are available on the Securities and Exchange Commission website or upon request.

3. Significant Accounting Policies.

Each Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services – Investment Companies. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. Each Fund’s Schedule of Investments lists any underlying mutual funds or exchange-traded funds (ETFs) but does not include the underlying holdings of these funds. The following summarizes the significant accounting policies of each Fund:

Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Board of Trustees (the Board) has delegated the day to day responsibility for the valuation of each Fund’s investments to the Fair Value Committee (the Committee) established by each Fund’s investment adviser. In accordance with valuation policies and procedures approved by the Board, each Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or currency exchange rates are not readily available or reliable, investments will be fair valued in good faith by the Committee, in accordance with procedures adopted by the Board. Factors used in determining fair value vary by investment type and may include market or investment specific events, changes in interest rates and credit quality. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees each Fund’s valuation policies and procedures and reports to the Board on the Committee’s activities and fair value determinations. The Board monitors the appropriateness of the procedures used in valuing each Fund’s investments and ratifies the fair value determinations of the Committee.

Each Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 – unadjusted quoted prices in active markets for identical investments

Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 – unobservable inputs (including the Fund’s own assumptions based on the best information available)

Valuation techniques used to value each Fund’s investments by major category are as follows:

121	Annual Report

Notes to Financial Statements – continued

3. Significant Accounting Policies – continued

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. Corporate bonds, bank loan obligations, foreign government and government agency obligations, municipal securities and U.S government and government agency obligations are valued by pricing vendors who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. Asset backed securities, collateralized mortgage obligations and U.S. government agency mortgage securities are valued by pricing vendors who utilize matrix pricing which considers prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. Swaps are marked-to-market daily based on valuations from third party pricing vendors, registered derivatives clearing organizations (clearinghouses) or broker-supplied valuations. These pricing sources may utilize inputs such as interest rate curves, credit spread curves, default possibilities and recovery rates. When independent prices are unavailable or unreliable, debt securities and swaps may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. For foreign debt securities, when significant market or security specific events arise, valuations may be determined in good faith in accordance with procedures adopted by the Board. Debt securities and swaps are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Equity securities, including restricted securities, for which market quotations are readily available, are valued at the last reported sale price or official closing price as reported by a third party pricing vendor on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. In the event there were no sales during the day or closing prices are not available, securities are valued at the last quoted bid price or may be valued using the last available price and are generally categorized as Level 2 in the hierarchy. For foreign equity securities, when market or security specific events arise, comparisons to the valuation of American Depositary Receipts (ADRs), futures contracts, Exchange-Traded Funds (ETFs) and certain indexes as well as quoted prices for similar securities may be used and would be categorized as Level 2 in the hierarchy. For equity securities, including restricted securities, where observable inputs are limited, assumptions about market activity and risk are used and these securities may be categorized as Level 3 in the hierarchy.

Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level as of August 31, 2022 is included at the end of each Fund’s Schedule of Investments.

Foreign Currency. Certain Funds may use foreign currency contracts to facilitate transactions in foreign-denominated securities. Gains and losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts' terms.

Foreign-denominated assets, including investment securities, and liabilities are translated into U.S. dollars at the exchange rates at period end. Purchases and sales of investment securities, income and dividends received, and expenses denominated in foreign currencies are translated into U.S. dollars at the exchange rate in effect on the transaction date.

The effects of exchange rate fluctuations on investments are included with the net realized and unrealized gain (loss) on investment securities. Other foreign currency transactions resulting in realized and unrealized gain (loss) are disclosed separately.

Investment Transactions and Income. For financial reporting purposes and for processing shareholder transactions, the Funds' investment holdings and NAV include trades executed through the end of the last business day of the period and prior business day, respectively. The NAV per share for processing shareholder transactions is calculated as of the close of business (normally 4:00 p.m. Eastern time) of the Cboe BZX Exchange, Inc. (CboeBZX) for Fidelity Low Duration Bond Factor ETF, and of the New York Stock Exchange, Archipelago Exchange (NYSE Arca) for all other funds. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Commissions paid to certain brokers with whom the investment adviser, or its affiliates, places trades on behalf of a fund include an amount in addition to trade execution, which may be rebated back to a fund. Any such rebates are included in net realized gain (loss) on investments in the Statements of Operations. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Funds are informed of the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Paid in Kind (PIK) income is recorded at the fair market value of the securities received. The principal amount on inflation-indexed securities is periodically adjusted to the rate of inflation and interest is accrued based on the principal amount. The adjustments to principal due to inflation are reflected as increases or decreases to Interest in the accompanying Statements of Operations. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain. Debt obligations may be placed on non-accrual status and related interest income may be reduced by ceasing current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured. The Fund earns certain fees in connection with its floating rate loan purchasing activities. These fees are in addition to interest payments earned and may include amendment fees, consent fees and prepayment fees. These fees are recorded as Interest in the

accompanying financial statements. Funds may file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld. Any withholding tax reclaims income is included in the Statements of Operations in interest. Any receivables for withholding tax reclaims are included in the Statements of Assets and Liabilities in interest receivable.

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expenses included in the accompanying financial statements reflect the expenses of that fund and do not include any expenses associated with any underlying mutual funds or exchange-traded funds. Although not included in a fund’s expenses, a fund indirectly bears its proportionate share of these expenses through the net asset value of each underlying mutual fund or exchange-traded fund. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, each Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. As of August 31, 2022, each Fund did not have any unrecognized tax benefits in the financial statements; nor is each Fund aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. Each Fund files a U.S. federal tax return, in addition to state and local tax returns as required. Each Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction. Realized gain or loss resulting from in-kind redemptions is not taxable to the Fund and is not distributed to shareholders of the Fund.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Capital accounts are not adjusted for temporary book-tax differences which will reverse in a subsequent period.

Book-tax differences are primarily due to futures transactions, defaulted bonds, prior period premium and discount on debt securities, redemptions in kind, capital loss carryforwards, and losses deferred due to wash sales and excise tax regulations.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows for each Fund:

	Tax cost	Gross unrealized appreciation	Gross unrealized depreciation	Net unrealized appreciation (depreciation)
Fidelity Corporate Bond ETF	$ 184,197,390	$ 20,834	$ (25,725,194)	$ (25,704,360)

^A	For the period March 2, 2021 (commencement of operations) through August 31, 2021.

Delayed Delivery Transactions and When-Issued Securities. During the period, certain Funds transacted in securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Securities purchased on a delayed delivery or when-issued basis are identified as such in the Schedule of Investments. Compensation for interest forgone in the purchase of a delayed delivery or when-issued debt security may be received. With respect to purchase commitments, each applicable Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Payables and receivables associated with the purchases and sales of delayed delivery securities having the same coupon, settlement date and broker are offset. Delayed delivery or when-issued securities that have been purchased from and sold to different brokers are reflected as both payables and receivables in the Statement of Assets and Liabilities under the caption "Delayed delivery", as applicable. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract’s terms, or if the issuer does not issue the securities due to political, economic, or other factors.

To-Be-Announced (TBA) Securities and Mortgage Dollar Rolls. TBA securities involve buying or selling mortgage-backed securities (MBS) on a forward commitment basis. A TBA transaction typically does not designate the actual security to be delivered and only includes an approximate principal amount; however delivered securities must meet specified terms defined by industry guidelines, including issuer, rate and current principal amount outstanding on underlying mortgage pools. Funds may enter into a TBA transaction with the intent to take possession of or deliver the underlying MBS, or a fund may elect to extend the settlement by entering into either a mortgage or reverse mortgage dollar roll. Mortgage dollar rolls are transactions where a fund sells TBA securities and simultaneously agrees to repurchase MBS on a later date at a lower price and with the same counterparty. Reverse mortgage dollar rolls involve the purchase and simultaneous agreement to sell TBA securities on a later date at a lower price. Transactions in mortgage dollar rolls and reverse mortgage dollar rolls are accounted for as purchases and sales and may result in an increase to a fund’s portfolio turnover rate.

3. Significant Accounting Policies – continued

Purchases and sales of TBA securities involve risks similar to those discussed above for delayed delivery and when-issued securities. Also, if the counterparty in a mortgage dollar roll or a reverse mortgage dollar roll transaction files for bankruptcy or becomes insolvent, a Funds' right to repurchase or sell securities may be limited. Additionally, when a fund sells TBA securities without already owning or having the right to obtain the deliverable securities (an uncovered forward commitment to sell), it incurs a risk of loss because it could have to purchase the securities at a price that is higher than the price at which it sold them. A fund may be unable to purchase the deliverable securities if the corresponding market is illiquid.

TBA securities subject to a forward commitment to sell at period end are included at the end of each applicable Fund's Schedule of Investments under the caption "TBA Sale Commitments.” The proceeds and value of these commitments are reflected in the each applicable Fund's Statement of Assets and Liabilities as Receivable for TBA sale commitments and TBA sale commitments, at value, respectively.

Restricted Securities (including Private Placements). Funds may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities held at period end is included at the end of the Schedule of Investments, if applicable.

Loans and Other Direct Debt Instruments. Direct debt instruments are interests in amounts owed to lenders by corporate or other borrowers. These instruments may be in the form of loans, trade claims or other receivables and may include standby financing commitments such as revolving credit facilities that obligate a fund to supply additional cash to the borrower on demand. Loans may be acquired through assignment, participation, or may be made directly to a borrower. Such instruments are presented in the Bank Loan Obligations section in the Schedule of Investments. Certain funds may also invest in unfunded loan commitments, which are contractual obligations for future funding. Information regarding unfunded commitments is included at the end of the Schedule of Investments, if applicable.

New Accounting Pronouncement. In March 2020, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU), ASU 2020-04, which provides optional, temporary relief with respect to the financial reporting of contracts subject to certain types of modifications due to the planned discontinuation of the London Interbank Offered Rate (LIBOR) and other IBOR-based reference rates. The temporary relief provided by ASU 2020-04 is effective for certain reference rate-related contract modifications that occur during the period March 12, 2020 through December 31, 2022. Management does not expect the adoption of ASU 2020-04 to have a material impact on the Fund’s financial statements.

4. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. Investment objectives allow a fund to enter into various types of derivative contracts, including futures contracts, options and swaps. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party.

Derivatives were used to increase returns and to manage exposure to certain risks as defined below. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the objectives may not be achieved.

Derivatives were used to increase or decrease exposure to the following risk(s):

Credit Risk Credit risk relates to the ability of the issuer of a financial instrument to make further principal or interest payments on an obligation or commitment that it has to a fund.

Interest Rate Risk Interest rate risk relates to the fluctuations in the value of interest-bearing securities due to changes in the prevailing levels of market interest rates.

The Funds are also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that the Funds will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to the Funds. Derivative counterparty credit risk is managed through formal evaluation of the creditworthiness of all potential counterparties. On certain OTC derivatives such as options and bi-lateral swaps, the Funds attempt to reduce their exposure to counterparty credit risk by entering into an International Swaps and Derivatives Association, Inc. (ISDA) Master Agreement with each of its counterparties. The ISDA Master Agreement gives the Funds the right to terminate all transactions traded under such agreement upon the deterioration in the credit quality of the counterparty beyond specified levels. The ISDA Master Agreement gives each party the right, upon an event of default by the other party or a termination of the agreement, to close out all transactions traded under such agreement and to net amounts owed under each transaction to one net payable by one party to the other. To mitigate counterparty credit risk on bi-lateral OTC derivatives, the Funds receive collateral in the form of cash or securities once each Fund’s net unrealized appreciation on

Notes to Financial Statements – continued

4. Derivative Instruments – continued

outstanding derivative contracts under an ISDA Master Agreement exceeds certain applicable thresholds, subject to certain minimum transfer provisions. The collateral received is held in segregated accounts with the Funds’ custodian bank in accordance with the collateral agreements entered into between the Funds, the counterparty and the Funds’ custodian bank. The Funds could experience delays and costs in gaining access to the collateral even though it is held by the Funds’ custodian bank. The Funds’ maximum risk of loss from counterparty credit risk related to bi-lateral OTC derivatives is generally the aggregate unrealized appreciation and unpaid counterparty payments in excess of any collateral pledged by the counterparty to the Funds. The Funds may be required to pledge collateral for the benefit of the counterparties on bi-lateral OTC derivatives in an amount not less than each counterparty’s unrealized appreciation on outstanding derivative contracts, subject to certain minimum transfer provisions, and any such pledged collateral is identified in the Schedule of Investments. Exchange-traded futures contracts and exchange-traded options are not covered by the ISDA Master Agreement; however counterparty credit risk related to exchange-traded futures contracts and exchange-traded options may be mitigated by the protection provided by the exchange on which they trade. Counterparty credit risk related to centrally cleared OTC swaps may be mitigated by the protection provided by the clearinghouse.

Investing in derivatives may involve greater risks than investing in the underlying assets directly and, to varying degrees, may involve risk of loss in excess of any initial investment and collateral received and amounts recognized in the Statements of Assets and Liabilities. In addition, there may be the risk that the change in value of the derivative contract does not correspond to the change in value of the underlying instrument.

Net Realized Gain (Loss) and Change in Net Unrealized Appreciation (Depreciation) on Derivatives. The table below, which reflects the impacts of derivatives on the financial performance, summarizes the net realized gain (loss) and change in net unrealized appreciation (depreciation) for derivatives during the period as presented in the Statement of Operations.

A summary of the value of derivatives by primary risk exposure as of period end is included at the end of the Schedule of Investments.

Futures Contracts. A futures contract is an agreement between two parties to buy or sell a specified underlying instrument for a fixed price at a specified future date. Futures contracts were used to manage exposure to the bond market and fluctuations in interest rates.

or (depreciation). This receivable and/or payable, if any, is included in daily variation margin on futures contracts in the Statement of Assets and Liabilities. Realized gain or (loss) is recorded upon the expiration or closing of a futures contract. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on futures contracts during the period is presented in the Statement of Operations.

Any open futures contracts at period end are presented in the Schedule of Investments under the caption “Futures Contracts”. The notional amount at value reflects each contract’s exposure to the underlying instrument or index at period end, and is representative of volume of activity during the period unless an average notional amount is presented. Any securities deposited to meet initial margin requirements are identified in the Schedule of Investments. Any cash deposited to meet initial margin requirements is presented as segregated cash with brokers for derivative instruments in the Statement of Assets and Liabilities.

Options. Options give the purchaser the right, but not the obligation, to buy (call) or sell (put) an underlying security or financial instrument at an agreed exercise or strike price between or on certain dates. Options obligate the seller (writer) to buy (put) or sell (call) an underlying instrument at the exercise or strike price or cash settle an underlying derivative instrument if the holder exercises the option on or before the expiration date. OTC options, such as swaptions, which are options where the underlying instrument is a swap, were used to manage exposure to fluctuations in interest rates.

Upon entering into an options contract, a fund will pay or receive a premium. Premiums paid on purchased options are reflected as cost of investments and premiums received on written options are reflected as a liability on the Statement of Assets and Liabilities. Certain options may be purchased or written with premiums to be paid or received on a future date. Options are valued daily and any unrealized appreciation (depreciation) is reflected on the Statement of Assets and Liabilities. When an option is exercised, the cost or proceeds of the underlying instrument purchased or sold is adjusted by the amount of the premium. When an option is closed, a gain or loss is realized depending on whether the proceeds or amount paid for the closing sale transaction is greater or less than the premium received or paid. When an option expires, gains and losses are realized to the extent of premiums received and paid, respectively. The net realized and unrealized gains (losses) on purchased options are included in the Statement of Operations in net realized gain (loss) and change in net unrealized appreciation (depreciation) on investment securities. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on written options are presented in the Statement of Operations.

Any open options at period end are presented in the Schedule of Investments under the captions “Purchased Options,” “Purchased Swaptions,” “Written Options” and “Written Swaptions,” as applicable, and are representative of volume of activity during the period unless an average notional amount is presented.

Writing puts and buying calls tend to increase exposure to the underlying instrument while buying puts and writing calls tend to decrease exposure to the underlying instrument. For purchased options, risk of loss is limited to the premium paid, and for written options, risk of loss is the change in value in excess of the premium received.

Swaps. A swap is a contract between two parties to exchange future cash flows at periodic intervals based on a notional principal amount. A bi-lateral OTC swap is a transaction between a fund and a dealer counterparty where cash flows are exchanged between the two parties for the life of the swap. A centrally cleared OTC swap is a transaction executed between a fund and a dealer counterparty, then cleared by a futures commission merchant (FCM) through a clearinghouse. Once cleared, the clearinghouse serves as a central counterparty, with whom a fund exchanges cash flows for the life of the transaction, similar to transactions in futures contracts.

Bi-lateral OTC swaps are marked-to-market daily and changes in value are reflected in the Statement of Assets and Liabilities in the bi-lateral OTC swaps at value line items. Any upfront premiums paid or received upon entering a bi-lateral OTC swap to compensate for differences between stated terms of the swap and prevailing market conditions (e.g. credit spreads, interest rates or other factors) are recorded in net unrealized appreciation (depreciation) in the Statement of Assets and Liabilities and amortized to realized gain or (loss) ratably over the term of the swap. Any unamortized upfront premiums are presented in the Schedule of Investments.

Centrally cleared OTC swaps require a fund to deposit either cash or securities (initial margin) with the FCM, at the instruction of and for the benefit of the clearinghouse. Any securities deposited to meet initial margin requirements are identified in the Schedule of Investments. Any cash deposited to meet initial margin requirements is presented in segregated cash with brokers for derivative instruments in the Statement of Assets and Liabilities. Centrally cleared OTC swaps are marked-to-market daily and subsequent payments (variation margin) are made or received depending on the daily fluctuations in the value of the swaps and are recorded as unrealized appreciation or (depreciation). These daily payments, if any, are included in receivable or payable for daily variation margin on centrally cleared OTC swaps in the Statement of Assets and Liabilities. Any premiums for centrally cleared OTC swaps are recorded periodically throughout the term of the swap to variation margin and included in unrealized appreciation (depreciation) in the Statement of Assets and Liabilities. Any premiums are recognized as realized gain (loss) upon termination or maturity of the swap.

For both bi-lateral and centrally cleared OTC swaps, payments are exchanged at specified intervals, accrued daily commencing with the effective date of the contract and recorded as realized gain or (loss). Some swaps may be terminated prior to the effective date and realize a gain or loss upon termination. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on swaps during the period is presented in the Statement of Operations.

Any open swaps at period end are included in the Schedule of Investments under the caption “Swaps”, and are representative of volume of activity during the period unless an average notional amount is presented.

Credit Default Swaps. Credit default swaps enable a fund to buy or sell protection against specified credit events on a single-name issuer or a traded credit index. Under the terms of a credit default swap the buyer of protection (buyer) receives credit protection in exchange for making periodic payments to the seller of protection (seller) based on a fixed percentage applied to a notional principal amount. In return for these payments, the seller will be required to make a payment upon the occurrence of one or more specified credit events. A fund enters into credit default swaps as a seller to gain credit exposure to an issuer and/or as a buyer to obtain a measure of protection against defaults of an issuer. Periodic payments are made over the life of the contract by the buyer provided that no credit event occurs.

For credit default swaps on most corporate and sovereign issuers, credit events include bankruptcy, failure to pay or repudiation/moratorium. For credit default swaps on corporate or sovereign issuers, the obligation that may be put to the seller is not limited to the specific reference obligation described in the Schedule of Investments. For credit default swaps on asset-backed securities, a credit event may be triggered by events such as failure to pay principal, maturity extension, rating downgrade or write-down. For credit default swaps on asset-backed securities, the reference obligation described represents the security that may be put to the seller. For credit default swaps on a traded credit index, a specified credit event may affect all or individual underlying securities included in the index.

As a seller, if an underlying credit event occurs, a fund will pay a net settlement amount of cash equal to the notional amount of the swap less the recovery value of the reference obligation or underlying securities comprising an index. Only in the event of the industry’s inability to value the underlying asset will a fund be required to take delivery of the reference obligation or underlying securities comprising an index and pay an amount equal to the notional amount of the swap.

As a buyer, if an underlying credit event occurs, a fund will receive a net settlement amount of cash equal to the notional amount of the swap less the recovery value of the reference obligation or underlying securities comprising an index. Only in the event of the industry’s inability to value the underlying asset will a fund be required to deliver the reference obligation or underlying securities comprising an index in exchange for payment of an amount equal to the notional amount of the swap.

Typically, the value of each credit default swap and credit rating disclosed for each reference obligation in the Schedule of Investments, where a fund is the seller, can be used as measures of the current payment/performance risk of the swap. As the value of the swap changes as a positive or negative percentage of the total notional amount, the payment/performance risk may decrease or increase, respectively. In addition to these measures, the investment adviser monitors a variety of factors including cash flow assumptions, market activity and market sentiment as part of its ongoing process of assessing payment/performance risk.

Interest Rate Swaps. Interest rate swaps are agreements between counterparties to exchange cash flows, one based on a fixed rate, and the other on a floating rate. A fund enters into interest rate swaps to manage its exposure to interest rate changes. Changes in interest rates can have an effect on both the value of bond holdings as well as the amount of interest income earned. In general, the value of bonds can fall when interest rates rise and can rise when interest rates fall.

6. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company LLC (the investment adviser) provides the Funds with investment management related services for which the Funds pay a monthly management fee that is based on an annual rate of .36% of each Fund's average net assets for Fidelity Corporate Bond ETF, Fidelity Investment Grade Bond ETF, Fidelity Investment Grade Securitized ETF, Fidelity Limited Term Bond ETF and Fidelity Total Bond ETF. Under the management contract, the investment adviser pays all other expenses, except the compensation of the independent Trustees and certain other expenses such as interest expense. For Fidelity Corporate Bond ETF, Fidelity Limited Term Bond ETF and Fidelity Total Bond ETF, the management fee paid to the investment adviser is reduced by an amount equal to the fees and expenses paid by each fund to the independent Trustees.

Fidelity Low Duration Bond Factor ETF's management fee is based on an annual rate of .15% of average net assets. Under the management contract, the investment adviser pays all other expenses, except the compensation of the independent Trustees and certain miscellaneous expenses such as proxy and shareholder meeting expenses.

Brokerage Commissions. A portion of portfolio transactions were placed with brokerage firms which are affiliates of the investment adviser. Brokerage commissions are included in the net realized gain (loss) and change in net unrealized appreciation (depreciation) in the Statements of Operations. The commissions paid to these affiliated firms were as follows:

	Amount
Fidelity Total Bond ETF	$ $ 1

Interfund Trades. Funds may purchase from or sell securities to other funds affiliated with each sub-adviser under procedures adopted by the Board. The procedures have been designed to ensure these interfund trades are executed in accordance with Rule 17a-7 of the 1940 Act. Any interfund trades are included within the respective purchases and sales amounts shown in the Purchases and Sales of Investments note. During the period there were no interfund trades.

7. Committed Line of Credit.

Certain Funds participate with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the “line of credit”) to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The commitment fees on the pro-rata portion of the line of credit are borne by the investment adviser. During the period, there were no borrowings on this line of credit.

8. Expense Reductions.

Through arrangements with each applicable Fund’s custodian, credits realized as a result of certain uninvested cash balances were used to reduce each applicable Fund’s expenses by the following amounts:

	Amount
Fidelity Corporate Bond ETF	$ 97
Fidelity Investment Grade Bond ETF	15
Fidelity Investment Grade Securitized ETF	22
Fidelity Limited Term Bond ETF	75
Fidelity Low Duration Bond Factor ETF	408
Fidelity Total Bond ETF	3,249

9. Share Transactions.

Funds issue and redeem shares at NAV only with certain authorized participants in large increments known as Creation Units. Purchases of Creation Units are made by tendering a basket of designated securities and/or cash to a fund and redemption proceeds are paid with a basket of securities from a fund’s portfolio with a balancing cash component to equate the market value of the basket of securities delivered or redeemed to the NAV per Creation Unit on the transaction date. Cash may be substituted equivalent to the value of certain securities generally when they are not available in sufficient quantity for delivery. A fund’s shares are available in smaller increments to investors in the secondary market at market prices and may be subject to commissions. Authorized participants pay a transaction fee to the shareholder servicing agent when purchasing and redeeming Creation Units of a fund. The transaction fee is used to offset the costs associated with the issuance and redemption of Creation Units.

10. Other.

A fund’s organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the fund. In the normal course of business, a fund may also enter into contracts that provide general indemnifications. A fund’s maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against a fund. The risk of material loss from such claims is considered remote.

The Independent Trustees may waive this mandatory retirement age policy with respect to individual Trustees. Officers and Advisory Board Members hold office without limit in time, except that any officer or Advisory Board Member may resign or may be removed by a vote of a majority of the Trustees at any regular meeting or any special meeting of the Trustees. Except as indicated, each individual has held the office shown or other offices in the same company for the past five years.

The funds’ Statement of Additional Information (SAI) includes more information about the Trustees. To request a fee copy, call Fidelity at 1-800-FIDELITY.

Experience, Skills, Attributes, and Qualifiﬁcations of the Trustees. The Governance and Nominating Committee has adopted a statement of policy that describes the experience, qualifications, attributes, and skills that are necessary and desirable for potential Independent Trustee candidates (Statement of Policy). The Board believes that each Trustee satisfied at the time he or she was initially elected or appointed a Trustee, and continues to satisfy, the standards contemplated by the Statement of Policy. The Governance and Nominating Committee also engages professional search firms to help identify potential Independent Trustee candidates who have the experience, qualifications, attributes, and skills consistent with the Statement of Policy. From time to time, additional criteria based on the composition and skills of the current Independent Trustees, as well as experience or skills that may be appropriate in light of future changes to board composition, business conditions, and regulatory or other developments, have also been considered by the professional search firms and the Governance and Nominating Committee. In addition, the Board takes into account the Trustees' commitment and participation in Board and committee meetings, as well as their leadership of standing and ad hoc committees throughout their tenure.

In determining that a particular Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Trustees have balanced and diverse experience, qualifications, attributes, and skills, which allow the Board to operate effectively in governing each fund and protecting the interests of shareholders. Information about the specific experience, skills, attributes, and qualifications of each Trustee, which in each case led to the Board's conclusion that the Trustee should serve (or continue to serve) as a trustee of the funds, is provided below.

Board Structure and Oversight Function. Abigail P. Johnson is an interested person and currently serves as Chairman. The Trustees have determined that an interested Chairman is appropriate and benefits shareholders because an interested Chairman has a personal and professional stake in the quality and continuity of services provided to the funds. Independent Trustees exercise their informed business judgment to appoint an individual of their choosing to serve as Chairman, regardless of whether the Trustee happens to be independent or a member of management. The Independent Trustees have determined that they can act independently and effectively without having an Independent Trustee serve as Chairman and that a key structural component for assuring that they are in a position to do so is for the Independent Trustees to constitute a substantial majority for the Board. The Independent Trustees also regularly meet in executive session. Michael E. Kenneally serves as Chairman of the Independent Trustees and as such (i) acts as a liaison between the Independent Trustees and management with respect to matters important to the Independent Trustees and (ii) with management prepares agendas for Board meetings.

Fidelity^® funds are overseen by different Boards of Trustees. The funds’ Board oversees Fidelity's investment-grade bond, money market, asset allocation and certain equity funds, and other Boards oversee Fidelity's high income and other equity funds. The asset allocation funds may invest in Fidelity^® funds that are overseen by such other Boards. The use of separate Boards, each with its own committee structure, allows the Trustees of each group of Fidelity^® funds to focus on the unique issues of the funds they oversee, including common research, investment, and operational issues. On occasion, the separate Boards establish joint committees to address issues of overlapping consequences for the Fidelity® funds overseen by each Board.

Annual Report

Table of Contents

The Trustees operate using a system of committees to facilitate the timely and efficient consideration of all matters of importance to the Trustees, each fund, and fund shareholders and to facilitate compliance with legal and regulatory requirements and oversight of the funds’ activities and associated risks. The Board, acting through its committees, has charged FMR and its affiliates with (i) identifying events or circumstances the occurrence of which could have demonstrably adverse effects on the funds’ business and/or reputation; (ii) implementing processes and controls to lessen the possibility that such events or circumstances occur or to mitigate the effects of such events or circumstances if they do occur; and (iii) creating and maintaining a system designed to evaluate continuously business and market conditions in order to facilitate the identification and implementation processes described in (i) and (ii) above. Because the day-to-day operations and activities of the funds are carried out by or through FMR, its affiliates, and other service providers, the funds’ exposure to risks is mitigated but not eliminated by the processes overseen by the Trustees. While each of the Board's committees has responsibility for overseeing different aspects of the funds’ activities, oversight is exercised primarily through the Operations and Audit Committees. In addition, an ad hoc Board committee of Independent Trustees has worked with FMR to enhance the Board's oversight of investment and financial risks, legal and regulatory risks, technology risks, and operational risks, including the development of additional risk reporting to the Board. Appropriate personnel, including but not limited to the funds’ Chief Compliance Officer (CCO), FMR's internal auditor, the independent accountants, the funds’ Treasurer and portfolio management personnel, make periodic reports to the Board's committees, as appropriate, including an annual review of Fidelity's risk management program for the Fidelity® funds. The responsibilities of each standing committee, including their oversight responsibilities, are described further under "Standing Committees of the Trustees."

Table of Contents

Shareholder Expense Example (Unaudited)

As a shareholder, you incur two types of costs: (1) transaction costs, which may include sales charges (loads) on purchase payments or redemption proceeds, as applicable and (2) ongoing costs, which generally include management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in a fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested for the one-half year period (March 1, 2022 to August 31, 2022).

Actual Expenses

The first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class/Fund under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period. If any fund is a shareholder of any underlying mutual funds or exchange-traded funds (ETFs) (the Underlying Funds), such fund indirectly bears its proportional share of the expenses of the Underlying Funds in addition to the direct expenses incurred presented in the table. These fees and expenses are not included in the annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. If any fund is a shareholder of any Underlying Funds, such fund indirectly bears its proportional share of the expenses of the Underlying Funds in addition to the direct expenses as presented in the table. These fees and expenses are not included in the annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

	Annualized Expense Ratio^A	Beginning Account Value March 1, 2022	Ending Account Value August 31, 2022	Expenses Paid During Period^B March 1, 2022 to August 31, 2022

Hypothetical ^C		$ 1,000.00	$ 1,023.39	$ 1.84

^A	Annualized expense ratio reflects expenses net of applicable fee waivers.
^B	Expenses are equal to the annualized expense ratio, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period). The fees and expenses of any Underlying Funds are not included in each annualized expense ratio.

Market Recap

The ICE BofA^® US High Yield Constrained Index returned -10.43% for the 12 months ending August 31, 2022, as a multitude of crosscurrents challenged the global economy and financial markets. Persistently high inflation, exacerbated by energy price shocks from the Russia–Ukraine conflict, spurred the U.S. Federal Reserve to hike interest rates more aggressively than anticipated, and concerns about the outlook for economic growth sent stocks into bear market territory. In early May, the Fed approved a rare half-percentage-point interest rate increase and announced plans to shrink its $9 trillion asset portfolio. June began with the Fed allowing up to billions in Treasuries and mortgage bonds to mature every month without investing the proceeds. Two weeks later, the central bank raised rates by 0.75 percentage points, its largest increase since 1994, and said it was becoming more difficult to achieve a soft landing, in which the economy slows enough to bring down inflation while avoiding a recession. Against this volatile backdrop, the index returned -14.03% in the first half of 2022. High yield sharply reversed course in July (+6.02%), even as the central bank again raised its benchmark interest rate by 0.75%, before a leg down in August (-2.39%). For the full 12 months, the health care and banking industries (-16% each) lagged most, followed by retail (-14%). In contrast, energy led the way, returning about -4% amid a surge in commodity prices, while transportation returned roughly -7%.

For the period ended August 31, 2022

1. Organization.

Fidelity Sustainable Core Plus Bond ETF and Fidelity Sustainable Low Duration Bond ETF (the Funds) are exchange-traded funds of Fidelity Merrimack Street Trust (the Trust) and are authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect exposure to certain issuers, sectors, regions, and countries and may affect performance depending on whether certain investments are in or out of favor. The criteria related to ESG ratings process and/or adherence to its sustainable investing exclusion criteria may result in forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so, or selling securities for ESG reasons when it might be otherwise disadvantageous for it to do so. As a result, performance may at times be better or worse than the performance of funds that do not use ESG or sustainability criteria. There are significant differences in interpretations of what it means for an issuer to have positive ESG factors. While the investment adviser believes its definitions are reasonable, the portfolio decisions it makes may differ with other investors’ or advisers’ views.

3. Significant Accounting Policies.

Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Board of Trustees (the Board) has delegated the day to day responsibility for the valuation of each Fund’s investments to the Fair Value Committee (the Committee) established by each Fund’s investment adviser. In accordance with valuation policies and procedures approved by the Board, each Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or currency exchange rates are not readily available or reliable, investments will be fair valued in good faith by the Committee, in accordance with procedures adopted by the Board. Factors used in determining fair value vary by investment type and may include market or investment specific events. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees each Fund’s valuation policies and procedures and reports to the Board on the Committee’s activities and fair value determinations. The Board monitors the appropriateness of the procedures used in valuing each Fund’s investments and ratifies the fair value determinations of the Committee.

Each Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

27	Annual Report

Table of Contents

Notes to Financial Statements – continued

3. Significant Accounting Policies – continued

Level 1 – unadjusted quoted prices in active markets for identical investments

Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 – unobservable inputs (including the Fund’s own assumptions based on the best information available)

Valuation techniques used to value each Fund’s investments by major category are as follows:

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. Corporate bonds, bank loan obligations, foreign government and government agency obligations, municipal securities and U.S government and government agency obligations are valued by pricing vendors who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. Asset backed securities, collateralized mortgage obligations and U.S. government agency mortgage securities are valued by pricing vendors who utilize matrix pricing which considers prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. For foreign debt securities, when significant market or security specific events arise, valuations may be determined in good faith in accordance with procedures adopted by the Board. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

The U.S. dollar value of foreign currency contracts is determined using currency exchange rates supplied by a pricing service and are categorized as Level 2 in the hierarchy.

may be placed on non-accrual status and related interest income may be reduced by ceasing current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Book-tax differences are primarily due to capital loss carryforwards, premium and discount on debt securities, equity-debt classifications, foreign currency transactions, futures transactions, and losses deferred due to wash sales.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows for each Fund:

	Tax cost	Gross unrealized appreciation	Gross unrealized depreciation	Net unrealized appreciation (depreciation)
Fidelity Sustainable Core Plus Bond ETF	$ 12,122,995	$ 2,199	$ (523,665)	$ (521,466)
Fidelity Sustainable Low Duration Bond ETF	5,287,586	148	(20,446)	(20,298)

The tax-based components of distributable earnings as of period end were as follows for each Fund:

Purchases and sales of TBA securities involve risks similar to those discussed above for delayed delivery and when-issued securities. Also, if the counterparty in a mortgage dollar roll or a reverse mortgage dollar roll transaction files for bankruptcy or becomes insolvent, a Funds' right to repurchase or sell securities may be limited. Additionally, when a fund sells TBA securities without already owning or having the right to obtain the deliverable securities (an uncovered forward commitment to sell), it incurs a risk of loss because it could have to purchase the securities at a price that is higher than the price at which it sold them. A fund may be unable to purchase the deliverable securities if the corresponding market is illiquid.

4. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. Investment objectives allow a fund to enter into various types of derivative contracts, including futures contracts and forward foreign currency contracts. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party.

Derivatives were used to increase or decrease exposure to the following risk(s):

Annual Report

Table of Contents

4. Derivative Instruments – continued

Foreign Exchange Risk Foreign exchange rate risk relates to fluctuations in the value of an asset or liability due to changes in currency exchange rates.

Interest Rate Risk Interest rate risk relates to the fluctuations in the value of interest-bearing securities due to changes in the prevailing levels of market interest rates.

Funds are also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that a fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to a fund. Derivative counterparty credit risk is managed through formal evaluation of the creditworthiness of all potential counterparties. On certain OTC derivatives such as forward foreign currency contracts, a fund attempts to reduce its exposure to counterparty credit risk by entering into an International Swaps and Derivatives Association, Inc. (ISDA) Master Agreement with each of its counterparties. The ISDA Master Agreement gives a fund the right to terminate all transactions traded under such agreement upon the deterioration in the credit quality of the counterparty beyond specified levels. The ISDA Master Agreement gives each party the right, upon an event of default by the other party or a termination of the agreement, to close out all transactions traded under such agreement and to net amounts owed under each transaction to one net payable by one party to the other. To mitigate counterparty credit risk on bi-lateral OTC derivatives, a fund receives collateral in the form of cash or securities once net unrealized appreciation on outstanding derivative contracts under an ISDA Master Agreement exceeds certain applicable thresholds, subject to certain minimum transfer provisions. The collateral received is held in segregated accounts with the custodian bank in accordance with the collateral agreements entered into between a fund, the counterparty and the custodian bank. A fund could experience delays and costs in gaining access to the collateral even though it is held by the custodian bank. The maximum risk of loss to a fund from counterparty credit risk related to bi-lateral OTC derivatives is generally the aggregate unrealized appreciation and unpaid counterparty payments in excess of any collateral pledged by the counterparty to a fund. A fund may be required to pledge collateral for the benefit of the counterparties on bi-lateral OTC derivatives in an amount not less than each counterparty’s unrealized appreciation on outstanding derivative contracts, subject to certain minimum transfer provisions, and any such pledged collateral is identified in the Schedule of Investments.

Investing in derivatives may involve greater risks than investing in the underlying assets directly and, to varying degrees, may involve risk of loss in excess of any initial investment and collateral received and amounts recognized in the Statement of Assets and Liabilities. In addition, there may be the risk that the change in value of the derivative contract does not correspond to the change in value of the underlying instrument.

Primary Risk Exposure / Derivative Type	Net Realized Gain (Loss)	Change in Net Unrealized Appreciation (Depreciation)
Fidelity Sustainable Core Plus Bond ETF
Foreign Exchange Risk
Forward Foreign Currency Contracts	$ 32,070	$ 11,813
Total Foreign Exchange Risk	32,070	11,813
Interest Rate Risk
Futures Contracts	(323)	(1,137)
Total Interest Rate Risk	(323)	(1,137)
Totals	$ 31,747	$ 10,676

If there are any open positions at period end, a summary of the value of derivatives by primary risk exposure is included at the end of the Schedule of Investments.

Forward Foreign Currency Contracts. Forward foreign currency contracts represent obligations to purchase or sell foreign currency on a specified future date at a price fixed at the time the contracts are entered into. Forward foreign currency contracts were used to facilitate transactions in foreign-denominated securities and to manage exposure to certain foreign currencies.

Forward foreign currency contracts are valued daily and fluctuations in exchange rates on open contracts are recorded as unrealized appreciation or (depreciation) and reflected in the Statement of Assets and Liabilities. When the contract is closed, a gain or loss is realized equal to the difference between the closing value and the value at the time it was opened. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in cash without the delivery of foreign currency. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on forward foreign currency contracts during the period is presented in the Statement of Operations.

4. Derivative Instruments – continued

Any open forward foreign currency contracts at period end are presented in the Schedule of Investments under the caption “Forward Foreign Currency Contracts.” The contract amount and unrealized appreciation (depreciation) reflects each contract’s exposure to the underlying currency at period end, and is representative of volume of activity during the period unless an average contract value is presented.

Upon entering into a futures contract, a fund is required to deposit either cash or securities (initial margin) with a clearing broker in an amount equal to a certain percentage of the face value of the contract. Futures contracts are marked-to-market daily and subsequent daily payments are made or received by a fund depending on the daily fluctuations in the value of the futures contracts and are recorded as unrealized appreciation or (depreciation). This receivable and/or payable, if any, is included in daily variation margin on futures contracts in the Statement of Assets and Liabilities. Realized gain or (loss) is recorded upon the expiration or closing of a futures contract. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on futures contracts during the period is presented in the Statements of Operations.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Merrimack Street Trust and the Shareholders of Fidelity Sustainable Core Plus Bond ETF and Fidelity Sustainable Low Duration Bond ETF:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statements of assets and liabilities of Fidelity Sustainable Core Plus Bond ETF and Fidelity Sustainable Low Duration Bond ETF (the “Funds”), each a fund of Fidelity Merrimack Street Trust, including the schedules of investments, as of August 31, 2022, the related statements of operations, the statements of changes in net assets and the financial highlights for the period from April 19, 2022 (commencement of operations) through August 31, 2022, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of each of the Funds as of August 31, 2022, and the results of their operations, the changes in their net assets and the financial highlights for the period from April 19, 2022 (commencement of operations) through August 31, 2022, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of August 31, 2022, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Sustainable Core Plus Bond ETF

At its March 2022 meeting, the Board of Trustees, including the Independent Trustees (together, the Board), voted to approve the management contract with Fidelity Management & Research Company LLC (FMR) and the sub-advisory agreements with affiliates of FMR (together, the Advisory Contracts) for the fund. FMR and the sub-advisers are collectively referred to herein as the Investment Advisers. The Board, assisted by the advice of fund counsel and Independent Trustees’ counsel, considered a broad range of information.

Nature, Extent, and Quality of Services Provided. The Board considered Fidelity’s staffing as it relates to the fund, including the backgrounds of investment personnel of Fidelity, and also considered the fund’s investment objectives, strategies, and related investment philosophy. The Board considered the structure of the investment personnel compensation program and whether this structure provides appropriate incentives to act in the best interests of the fund.

Resources Dedicated to Investment Management and Support Services. The Board reviewed the general qualifications and capabilities of Fidelity’s investment staff, including its size, education, experience, and resources, as well as Fidelity’s approach to recruiting, training, managing, and compensating investment personnel. The Board noted the resources devoted to Fidelity’s global investment organization and that Fidelity’s analysts have extensive resources, tools and capabilities that allow them to conduct sophisticated quantitative and fundamental analysis, as well as credit analysis of issuers, counterparties and guarantors. Further, the Board considered that Fidelity’s investment professionals have sufficient access to global information and data so as to provide competitive investment results over time, and that those professionals also have access to sophisticated tools that permit them to assess portfolio construction and risk and performance attribution characteristics continuously, as well as to transmit new information and research conclusions rapidly around the world. Additionally, in its deliberations, the Board considered Fidelity’s trading, risk management, compliance, cybersecurity, and technology and operations capabilities and resources, which are integral parts of the investment management process.

Shareholder and Administrative Services. The Board considered the nature, extent, quality, and cost of advisory, administrative, and shareholder services to be performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering pricing and bookkeeping and securities lending services for the fund. The Board also considered the nature and extent of the supervision of third party service providers, principally transfer agents, custodians, subcustodians, and pricing vendors.

The Board noted that the growth of fund assets over time across the complex allows Fidelity to reinvest in the development of services designed to enhance the value and convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account information and market information over the Internet and through telephone representatives, investor education materials and asset allocation tools. The Board also considered that it reviews customer service metrics such as telephone response times, continuity of services on the website and metrics addressing services at Fidelity Investor Centers.

Investment Performance. The fund is a new fund and therefore had no historical performance for the Board to review at the time it approved the fund’s Advisory Contracts. The Board considered the Investment Advisers’ strength in fundamental, research-driven security selection, which the Board is familiar with through its supervision of other Fidelity funds. The Board also considered the fact that it oversees funds managed by FMR that have similar investment objectives and policies as the fund.

Based on its review, the Board concluded that the nature, extent, and quality of services to be provided to the fund under the Advisory Contracts should benefit the shareholders of the fund.

Competitiveness of Management Fee and Total Expense Ratio. In reviewing the Advisory Contracts, the Board considered the fund’s proposed all-inclusive (subject to certain exceptions) fee rate. The Board also considered other expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees, paid by FMR under the all-inclusive arrangement. The Board noted that the fund’s proposed management fee rate is below the median fee rate of funds with similar Lipper investment objective categories and comparable investment mandates, regardless of whether their management fee structures are comparable. The Board also considered that the projected total expense ratio of the fund is below the median of those funds and classes used by the Board for management fee comparisons that have a similar sales load structure.

Based on its review, the Board concluded that the fund’s management fee and projected total expense ratio were reasonable in light of the services that the fund and its shareholders will receive and the other factors considered.

Costs of the Services and Profitability. The fund is a new fund and therefore no revenue, cost, or profitability data was available for the Board to review in respect of the fund at the time it approved the Advisory Contracts. In connection with its future renewal of the fund’s Advisory Contracts, the Board will consider the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and servicing the fund’s shareholders.

Economies of Scale. The Board will consider economies of scale when there is operating experience to permit assessment thereof. It noted that, notwithstanding the entrepreneurial risk associated with a new fund, the management fee was at a level normally associated, by comparison with competitors, with very high fund net assets, and Fidelity asserted to the Board that the level of the fee anticipated economies of scale at lower asset levels even before, if ever, economies of scale are achieved. The Board also noted that the fund and its shareholders would have access to the very considerable number and variety of services available through Fidelity and its affiliates.

Table of Contents

Based on its evaluation of all of the conclusions noted above, and after considering all factors it believed relevant, the Board concluded that the advisory fee arrangements are fair and reasonable, and that the fund’s Advisory Contracts should be approved.
