Fidelity® Mid Cap Index Fund

Performance: The Bottom Line

Average annual total return reflects the change in the value of an investment, assuming reinvestment of distributions from dividend income and capital gains (the profits earned upon the sale of securities that have grown in value, if any) and assuming a constant rate of performance each year. The hypothetical investment and the average annual total returns do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. During periods of reimbursement by Fidelity, a fund’s total return will be greater than it would be had the reimbursement not occurred. How a fund did yesterday is no guarantee of how it will do tomorrow.

Management's Discussion of Fund Performance

Market Recap: The S&P 500^® index gained 13.49% for the 12 months ending April 30, 2019, as U.S. equities began the new year on a high note after enduring an historically volatile final quarter of 2018. The index rose 18.25% year to date, its strongest four-month opening since 1987, amid upbeat company earnings/outlooks and signs the Fed may pause on rates. After achieving a record close in late April, the S&P 500^® moved a bit higher to end the period. The uptrend was in sharp contrast to late 2018, when rising U.S. Treasury yields and concern about peaking corporate earnings growth sent many investors fleeing from risk assets as they were still dealing with lingering uncertainty related to global trade and the Fed picking up the pace of interest rate hikes. The index returned -6.84% in October, at the time its largest monthly drop in seven years. But conditions worsened through Christmas, as jitters about the economy and another hike in rates led to a spike in market volatility and a -9.03% result for December. For the full period, eight of 11 sectors registered a double-digit gain, led by information technology (+25%). Three defensive groups also stood out: real estate (+21%), consumer staples (+18%) and utilities (+18%). Communication services – a mix of telecom stocks and media/entertainment names – gained 17%, followed by consumer discretionary (+16%). In contrast, energy (-7%) lost ground, while materials (+3%), financials (+4%), health care (+11%) and industrials (+11%) also trailed the broad market.

Comments from the Geode Capital Management, LLC, passive equity index team: For the fiscal year, the fund performed roughly in line with the 10.69% gain of the benchmark Russell Midcap^® Index. Many top individual contributors this period came from the information technology sector – the strongest-performing sector in the index – led by ServiceNow (+63%). In January, this cloud-computing company reported very strong quarterly earnings, which lifted its shares. Increased strength in the semiconductor industry benefited shares of chipmakers Advanced Micro Devices (+154%), Xilinx (+90%) and Analog Devices (+36%). Shares of Workday (+65%), a maker of financial and HR-management software, rose as the company reported strong earnings. Also contributing was payment-processing company Worldpay (+44%), whose shares rose sharply in March after the company agreed to be acquired. In contrast, California utility PG&E (-49%) fell sharply due to potential losses and liability following last year's wildfires. Energy producer Concho Resources (-27%) struggled along with weakness in the energy sector for much of the period. Also detracting was Western Digital (-32%), whose shares reflected the company's disappointing financial results.

The views expressed above reflect those of the portfolio manager(s) only through the end of the period as stated on the cover of this report and do not necessarily represent the views of Fidelity or any other person in the Fidelity organization. Any such views are subject to change at any time based upon market or other conditions and Fidelity disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Fidelity fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any Fidelity fund.

Note to Shareholders: On March 22, 2019, Pat Waddell retired and is no longer a portfolio manager with Geode Capital Management.

Fidelity® Small Cap Index Fund

Management's Discussion of Fund Performance

Comments from the Geode Capital Management, LLC, passive equity team: For the fiscal year, the fund performed roughly in line with the 4.61% gain of the benchmark Russell 2000^® Index. Many top individual contributors this period came from the information technology sector – the strongest-performing sector in the index, led by Trade Desk (+333%). Shares of this online advertising marketplace continued to gain sharply as the company repeatedly reported better-than-expected financial results. Other technology-sector contributors included semiconductor-related companies Cree (+77%) and Integrated Device Tech (+76%), which was no longer held at period end, and software businesses Hubspot (+74%) and Coupa Software (+123%). Elsewhere, strong financial performance lifted shares of Etsy (+125%), an e-commerce web site, as well as discount retailer Five Below (+107%). In contrast, shares of biotechnology company Nektar Therapeutics (-37%), which was no longer held at period end, fell sharply early in the period in response to an unfavorable drug trial result. Shares of Stamps.com (-63%) struggled after the company terminated an important contract with the U.S. Postal Service. Also detracting was energy services company McDermott International (-57%).

Note to Shareholders: On March 22, 2019, Pat Waddell retired and is no longer a portfolio manager with Geode Capital Management.

Notes to Financial Statements

For the period ended April 30, 2019

1. Organization.

Fidelity Mid Cap Index Fund and Fidelity Small Cap Index Fund (the Funds) are funds of Fidelity Salem 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.

Effective after the close of business November 9, 2018, each Fund's publicly offered share classes were consolidated into a single share class. The surviving class is Fidelity Mid Cap Index Fund and Fidelity Small Cap Index Fund (formerly Institutional Premium class). All current fiscal period dollar and share amounts for the classes that closed, which are presented in the Notes to Financial Statements, are for the period May 1, 2018 through November 9, 2018.

2. Investments in Fidelity Central Funds.

The Funds 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 Funds' Schedules of Investments list each of the Fidelity Central Funds held as of period end, if any, as an investment of each Fund, but do not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, each Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of the investment adviser. Annualized expenses of the Money Market Central Funds as of their most recent shareholder report date are less than .005%.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds, which are not covered by the Funds' Report of Independent Registered Public Accounting Firm, are available on the SEC 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 – Investments 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. The following summarizes the significant accounting policies of the Funds:

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 – 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:

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.

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. 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. 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. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

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 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 April 30, 2019 is included at the end of each Fund's Schedule of Investments.

Foreign Currency. The 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, the Funds' investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and for certain Funds include proceeds received from litigation. 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. Certain distributions received by the Funds represent a return of capital or capital gain. The Funds determine the components of these distributions subsequent to the ex-dividend date, based upon receipt of tax filings or other correspondence relating to the underlying investment. These distributions are recorded as a reduction of cost of investments and/or as a realized gain. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

Class Allocations and Expenses. Investment income, realized and unrealized capital gains and losses, common expenses of each Fund, and certain fund-level expense reductions, if any, are allocated daily on a pro-rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent fees incurred. Certain expense reductions may also differ by class. For the reporting period, the allocated portion of income and expenses to each class as a percent of its average net assets may vary due to the timing of recording these transactions in relation to fluctuating net assets of the classes. 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. 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 April 30, 2019, 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. Foreign taxes are provided for based on each Fund's understanding of the tax rules and rates that exist in the foreign markets in which it invests.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. In addition, the Funds claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

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 future contracts, foreign currency transactions, passive foreign investment companies (PFIC), market discount, partnerships, 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 Mid Cap Index Fund	$8,561,743,231	$1,897,371,593	$(463,372,381)	$1,433,999,212

This Final Rule includes amendments specific to registered investment companies that are intended to eliminate overlap in disclosure requirements between Regulation S-X and GAAP. In accordance with these amendments, certain line-items in the Funds' financial statements have been combined or removed for the current period as outlined in the table below.

4. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Funds' investment objective allows the Funds to enter into various types of derivative contracts, including futures 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.

The Funds used derivatives 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 Funds may not achieve their objectives.

The Funds' use of derivatives increased or decreased their exposure to the following risk:

Equity Risk

Equity risk relates to the fluctuations in the value of financial instruments as a result of changes in market prices (other than those arising from interest rate risk or foreign exchange risk), whether caused by factors specific to an individual investment, its issuer, or all factors affecting all instruments traded in a market or market segment.

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. Counterparty credit risk related to exchange-traded futures contracts may be mitigated by the protection provided by the exchange on which they trade.

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.

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. The Funds used futures contracts to manage their exposure to the stock market.

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 (variation margin) 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 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. Securities deposited to meet initial margin requirements are identified in the Schedule of Investments. Cash deposited to meet initial margin requirements is presented as segregated cash with brokers for derivative instruments in the Statement of Assets and Liabilities.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, are noted in the table below.

	Purchases ($)	Sales ($)
Fidelity Mid Cap Index Fund	3,993,567,715	855,677,543
Fidelity Small Cap Index Fund	5,202,165,822	1,193,632,049

6. Fees and Other Transactions with Affiliates.

Management Fee and Expense Contract. Fidelity Management & Research Company (the investment adviser) and its affiliates provide the Funds with investment management related services for which the Funds pay a monthly management fee. Effective August 1, 2018, the Board approved an amendment to the management contract to reduce the management fee to an annual rate of .025% of each Fund's average net assets. Prior to August 1, 2018, the management fee was based on an annual rate of .035% of each Fund's average net assets. Under the management contract, the investment adviser pays all other fund-level expenses, except the compensation of the independent Trustees and certain other expenses such as interest expense, including commitment fees. For the reporting period, the total annualized management fee rate was .03% and .03% of Fidelity Mid Cap Index Fund and Fidelity Small Cap Index Fund's average net assets, respectively.

Effective August 1, 2018, the Board also approved an amendment to the expense contract. Under the expense contract, the investment adviser pays class-level expenses as necessary so that the total expenses do not exceed certain amounts of each class' average net assets on an annual basis with certain exceptions, as noted in the following table:

	Investor Class	Premium Class	Institutional Class	Index Fund Class
Fidelity Mid Cap Index Fund	.025%	.025%	.025%	.025%
Fidelity Small Cap Index Fund	.025%	.025%	.025%	.025%

Prior to August 1, 2018, the investment adviser paid class-level expenses as necessary so that the total expenses did not exceed certain amounts as noted in the following table:

	Investor Class	Premium Class	Institutional Class	Index Fund Class
Fidelity Mid Cap Index Fund	.17%	.05%	.04%	.035%
Fidelity Small Cap Index Fund	.17%	.05%	.04%	.035%

Sub-Adviser. Geode Capital Management, LLC (Geode), serves as sub-adviser for the Funds. Geode provides discretionary investment advisory services to the Funds and is paid by the investment adviser for providing these services.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Funds. FIIOC receives transfer agent fees at an annual rate of .21%, .11%, .035% and .015% of class-level average net assets for each Fund's Investor Class, Premium Class, Institutional Class and Index Fund Class, respectively. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements.

Effective August 1, 2018, under the amended expense contract, each Investor Class, Premium Class, Institutional Class and Index Fund Class do not pay transfer agent fees. Prior to August 1, 2018, under the expense contract, each Investor Class, Premium Class and Institutional Class paid a portion of the transfer agent fees at an annual rate of .135%, .015% and .005% of class-level average net assets, respectively, and Index Fund Class did not pay a transfer agent fee.

For the period, the total transfer agent fees paid by each applicable class were as follows:

	Amount	% of Class-Level Average Net Assets
Fidelity Mid Cap Index Fund
Investor Class	$25,749	.03
Premium Class	141,892	–^(a)
Institutional Class	25,597	–^(a)

(a) Amount represents less than .005%.

Interfund Lending Program. Pursuant to an Exemptive Order issued by the SEC, the Funds, along with other registered investment companies having management contracts with Fidelity Management & Research Company (FMR) or other affiliated entities of FMR, may participate in an interfund lending program. This program provides an alternative credit facility allowing the funds to borrow from, or lend money to, other participating affiliated funds. At period end, there were no interfund loans outstanding. Each applicable fund's activity in this program during the period for which loans were outstanding was as follows:

	Borrower or Lender	Average Loan Balance	Weighted Average Interest Rate	Interest Expense
Fidelity Mid Cap Index Fund	Borrower	$81,715,500	2.17%	$19,740
Fidelity Small Cap Index Fund	Borrower	$26,623,000	2.46%	$10,903

Interfund Trades. The Funds may purchase from or sell securities to other Fidelity Funds 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. Interfund trades are included within the respective purchases and sales amounts shown in the Purchases and Sales of Investments note.

Prior Fiscal Year Redemptions In-Kind. During the prior period, 1,400,887 shares of Fidelity Mid Cap Index Fund held by an affiliated entity were redeemed in-kind for investments and cash with a value of $29,194,489. The Fund had a net realized gain of $14,766,993 on investments delivered through in-kind redemptions. The amount of the in-kind redemptions is included in share transactions in the accompanying Statement of Changes in Net Assets as well as the Notes to Financial Statements. The Fund recognized no gain or loss for federal income tax purposes.

Prior Fiscal Year Redemptions In-Kind. During the prior period, 1,145,154 shares of Fidelity Small Cap Index Fund held by an affiliated entity were redeemed in-kind for investments and cash with a value of $23,567,263. The Fund had a net realized gain of $13,050,414 on investments delivered through in-kind redemptions. The amount of the in-kind redemptions is included in share transactions in the accompanying Statement of Changes in Net Assets as well as the Notes to Financial Statements. The Fund recognized no gain or loss for federal income tax purposes.

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 participating funds have agreed to pay commitment fees on their pro-rata portion of the line of credit, which are reflected in Commitment fees on the Statement of Operations, and are as follows:

Fidelity Mid Cap Index Fund	$18,968
Fidelity Small Cap Index Fund	16,689

During the period, the Funds did not borrow on this line of credit.

8. Security Lending.

Certain Funds lend portfolio securities through a lending agent from time to time in order to earn additional income. On the settlement date of the loan, each applicable Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Funds and any additional required collateral is delivered to the Funds on the next business day. The Funds or borrower may terminate the loan at any time, and if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Funds may apply collateral received from the borrower against the obligation. The Funds may experience delays and costs in recovering the securities loaned. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and cash collateral at period end are disclosed on each applicable Fund's Statement of Assets and Liabilities. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented on each applicable Fund's Statement of Operations as a component of income from Fidelity Central Funds. FCM security lending activity was as follows:

	Security Lending Income From Securities Loaned to FCM	Value of Securities Loaned to FCM at Period End
Fidelity Mid Cap Index Fund	$11,858	$–
Fidelity Small Cap Index Fund	$564,778	$11,809,935

9. Expense Reductions.

Through arrangements with each applicable Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expenses. All of the applicable expense reductions are noted in the table below.

	Expense reduction
Fidelity Mid Cap Index Fund	$1,325
Fidelity Small Cap Index Fund	3,188

12. Other.

The Funds' 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 Funds. In the normal course of business, the Funds may also enter into contracts that provide general indemnifications. The Funds' maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Funds. The risk of material loss from such claims is considered remote.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Salem Street Trust and the Shareholders of Fidelity Mid Cap Index Fund and Fidelity Small Cap Index Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statements of assets and liabilities of Fidelity Mid Cap Index Fund and Fidelity Small Cap Index Fund (the "Funds"), each a fund of Fidelity Salem Street Trust, including the schedules of investments, as of April 30, 2019, the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended, 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 April 30, 2019, and the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, 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 April 30, 2019, by correspondence with the custodians 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.

We have served as the auditor of one or more of the Fidelity investment companies since 1999.

Trustees and Officers

The Trustees, Members of the Advisory Board (if any), and officers of the trust and funds, as applicable, are listed below. The Board of Trustees governs each fund and is responsible for protecting the interests of shareholders. The Trustees are experienced executives who meet periodically throughout the year to oversee each fund's activities, review contractual arrangements with companies that provide services to each fund, oversee management of the risks associated with such activities and contractual arrangements, and review each fund's performance. Except for Jonathan Chiel, each of the Trustees oversees 264 funds. Mr. Chiel oversees 158 funds.

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust. Each Trustee who is not an interested person (as defined in the 1940 Act) of the trust and the funds is referred to herein as an Independent Trustee. Each Independent Trustee shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs. 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.

Each fund’s Statement of Additional Information (SAI) includes more information about the Trustees. To request a free copy, call Fidelity at 1-800-544-8544.

Experience, Skills, Attributes, and Qualifications 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. Arthur E. Johnson 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.

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."

Shareholder Expense Example

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Funds 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 at the beginning of the period and held for the entire period (November 1, 2018 to April 30, 2019).

Actual Expenses

The first line of the accompanying table for each fund 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 fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, each Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's 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 for each fund provides information about hypothetical account values and hypothetical expenses based on a fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's 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. In addition, each Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's 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 November 1, 2018	Ending Account Value April 30, 2019	Expenses Paid During Period-^B November 1, 2018 to April 30, 2019
Fidelity Mid Cap Index Fund	.03%
Actual		$1,000.00	$1,117.00	$.16
Hypothetical-^C		$1,000.00	$1,024.65	$.15

Actual		$1,000.00	$1,061.30	$.15
Hypothetical-^C		$1,000.00	$1,024.65	$.15

^A Annualized expense ratio reflects expenses net of applicable fee waivers.

^B Expenses are equal to each Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 181/ 365 (to reflect the one-half year period).

^C 5% return per year before expenses

Management's Discussion of Fund Performance

Comments from the Geode Capital Management, LLC, passive equity index team: For the fiscal year, the fund performed roughly in line with the 10.69% gain of the benchmark Russell Midcap^® Index. Many top individual contributors this period came from the information technology sector – the strongest-performing sector in the index – led by ServiceNow (+64%). In January, this cloud-computing company reported very strong quarterly earnings, which lifted its shares. Increased strength in the semiconductor industry benefited shares of chipmakers Advanced Micro Devices (+154%), Xilinx (+90%) and Analog Devices (+36%). Shares of Workday (+65%), a maker of financial and HR-management software, rose as the company reported strong earnings. Also contributing was payment-processing company Worldpay (+44%), whose shares rose sharply in March after the company agreed to be acquired. In contrast, California utility PG&E (-48%) fell sharply due to potential losses and liability following last year's wildfires. Energy producer Concho Resources (-27%) struggled along with weakness in the energy sector for much of the period. Also detracting was Western Digital (-33%), whose shares reflected the company's disappointing financial results.

Note to Shareholders: On March 22, 2019, Pat Waddell retired and is no longer a portfolio manager with Geode Capital Management.

Notes to Financial Statements

For the period ended April 30, 2019

1. Organization.

Fidelity Flex Mid Cap Index Fund (the Fund) is a fund of Fidelity Salem Street Trust (the Trust) and is authorized to issue an unlimited number of shares. Share transactions on the Statement of Changes in Net Assets may contain exchanges between affiliated funds. 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. The Fund is available only to certain fee-based accounts offered by Fidelity.

2. Investments in Fidelity Central Funds.

The Fund invests 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 Fund's Schedule of Investments lists each of the Fidelity Central Funds held as of period end, if any, as an investment of the Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

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

3. Significant Accounting Policies.

The 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 – Investments 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. The following summarizes the significant accounting policies of the 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 the Fund's investments to the Fair Value Committee (the Committee) established by the Fund's investment adviser. In accordance with valuation policies and procedures approved by the Board, the 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 the 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 the Fund's investments and ratifies the fair value determinations of the Committee.

The 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 – 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 the Fund's investments by major category are as follows:

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 April 30, 2019, is included at the end of the Fund's Schedule of Investments.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost. 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 Fund is 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. Certain distributions received by the Fund represent a return of capital or capital gain. The Fund determines the components of these distributions subsequent to the ex-dividend date, based upon receipt of tax filings or other correspondence relating to the underlying investment. These distributions are recorded as a reduction of cost of investments and/or as a realized gain. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

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. 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, the 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 April 30, 2019, the Fund did not have any unrecognized tax benefits in the financial statements; nor is the 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. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. The 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.

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. In addition, the Fund claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

Book-tax differences are primarily due to futures contracts, partnerships, short-term gain distribution from underlying funds 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:

Gross unrealized appreciation	$9,868,020
Gross unrealized depreciation	(3,902,160)
Net unrealized appreciation (depreciation)	$5,965,860
Tax Cost	$71,365,621

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

Undistributed ordinary income	$214,035
Net unrealized appreciation (depreciation) on securities and other investments	$5,965,860

The Fund intends to elect to defer to its next fiscal year $122,272 of capital losses recognized during the period November 1, 2018 to April 30, 2019.

The tax character of distributions paid was as follows:

	April 30, 2019	April 30, 2018
Ordinary Income	$1,164,859	$ 31,171
Long-term Capital Gains	25,767	636
Total	$1,190,626	$ 31,807

New Rule Issuance. During August 2018, the U.S. Securities and Exchange Commission issued Final Rule Release No. 33-10532, Disclosure Update and Simplification. This Final Rule includes amendments specific to registered investment companies that are intended to eliminate overlap in disclosure requirements between Regulation S-X and GAAP. In accordance with these amendments, certain line-items in the Fund's financial statements have been combined or removed for the current period as outlined in the table below.

Financial Statement	Current Line-Item Presentation (As Applicable)	Prior Line-Item Presentation (As Applicable)
Statement of Assets and Liabilities	Total distributable earnings (loss)	Undistributed/Distributions in excess of/Accumulated net investment income (loss) Accumulated/Undistributed net realized gain (loss) Net unrealized appreciation (depreciation)
Statement of Changes in Net Assets	N/A - removed	Undistributed/Distributions in excess of/Accumulated net investment income (loss) end of period
Statement of Changes in Net Assets	Distributions to shareholders	Distributions to shareholders from net investment income Distributions to shareholders from net realized gain

4. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Fund's investment objective allows the Fund to enter into various types of derivative contracts, including futures 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.

The Fund used derivatives 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 Fund may not achieve its objectives.

The Fund's use of derivatives increased or decreased its exposure to the following risk:

Equity Risk

The Fund is also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that the 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 the Fund. Counterparty credit risk related to exchange-traded futures contracts may be mitigated by the protection provided by the exchange on which they trade.

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. The Fund used futures contracts to manage its exposure to the stock market.

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. Cash deposited to meet initial margin requirements is presented as segregated cash with brokers for derivative instruments in the Statement of Assets and Liabilities.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $32,274,034 and $15,370,966, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company (the investment adviser) and its affiliates provide the Fund with investment management related services and the Fund does not pay any fees for these services. Under the management contract, the investment adviser or an affiliate pays all other expenses of the Fund, excluding fees and expenses of the independent Trustees, and certain miscellaneous expenses such as proxy and shareholder meeting expenses.

Sub-Adviser. Geode Capital Management, LLC (Geode), serves as sub-adviser for the Fund. Geode provides discretionary investment advisory services to the Fund and is paid by the investment adviser for providing these services.

Interfund Trades. The Fund may purchase from or sell securities to other Fidelity Funds 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. Interfund trades are included within the respective purchases and sales amounts shown in the Purchases and Sales of Investments note.

Prior Fiscal Year Exchanges In-Kind. During the prior period, an affiliated entity completed an exchange in-kind with the Fund. The affiliated entity delivered investments and cash valued at $29,194,489 in exchange for 2,588,164 shares of the Fund. The amount of in-kind exchanges is included in share transactions in the accompanying Statement of Changes in Net Assets. The Fund recognized no gain or loss for federal income tax purposes.

7. Committed Line of Credit.

The Fund participates 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 Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $161 and is reflected in Commitment fees on the Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The Fund or borrower may terminate the loan at any time, and if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Fund may apply collateral received from the borrower against the obligation. The Fund may experience delays and costs in recovering the securities loaned. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. At period end, there were no security loans outstanding with FCM. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from the Fidelity Central Funds. Total security lending income during the period amounted to $4,106, including $14 from securities loaned to FCM.

9. Expense Reductions.

Through arrangements with the Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's expenses by $64.

10. Other.

The 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, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

Report of Independent Registered Public Accounting Firm

To the Trustees of Fidelity Salem Street Trust and Shareholders of Fidelity Flex Mid Cap Index Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Fidelity Flex Mid Cap Index Fund (the "Fund"), a fund of Fidelity Salem Street Trust, including the schedule of investments, as of April 30, 2019, the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the two years in the period then ended and for the period from March 9, 2017 (commencement of operations) to April 30, 2017, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of April 30, 2019, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the two years in the period then ended and for the period from March 9, 2017 (commencement of operations) to April 30, 2017 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 Fund's management. Our responsibility is to express an opinion on the Fund's 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 Fund 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 Fund is not required to have, nor were we engaged to perform, an audit of its 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 Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

We have served as the auditor of one or more of the Fidelity investment companies since 1999.

Trustees and Officers

The Trustees, Members of the Advisory Board (if any), and officers of the trust and fund, as applicable, are listed below. The Board of Trustees governs the fund and is responsible for protecting the interests of shareholders. The Trustees are experienced executives who meet periodically throughout the year to oversee the fund's activities, review contractual arrangements with companies that provide services to the fund, oversee management of the risks associated with such activities and contractual arrangements, and review the fund's performance. Except for Jonathan Chiel, each of the Trustees oversees 264 funds. Mr. Chiel oversees 158 funds.

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust. Each Trustee who is not an interested person (as defined in the 1940 Act) of the trust and the fund is referred to herein as an Independent Trustee. Each Independent Trustee shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs. 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 fund’s Statement of Additional Information (SAI) includes more information about the Trustees. To request a free copy, call Fidelity at 1-800-544-3455 (for managed account clients) or 1-800-835-5092 (for retirement plan participants).

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 the 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 fund, 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 fund. 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. Arthur E. Johnson 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 fund's 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.

The Trustees operate using a system of committees to facilitate the timely and efficient consideration of all matters of importance to the Trustees, the fund, and fund shareholders and to facilitate compliance with legal and regulatory requirements and oversight of the fund's 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 fund's 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 fund are carried out by or through FMR, its affiliates, and other service providers, the fund's 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 fund's 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 fund's Chief Compliance Officer (CCO), FMR's internal auditor, the independent accountants, the fund's 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."

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, and (2) ongoing costs, including other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the 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 at the beginning of the period and held for the entire period (November 1, 2018 to April 30, 2019).

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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's 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 Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's 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. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

	Annualized Expense Ratio-^A	Beginning Account Value November 1, 2018	Ending Account Value April 30, 2019	Expenses Paid During Period-^B November 1, 2018 to April 30, 2019
Actual	- %-^C	$1,000.00	$1,117.30	$--^D
Hypothetical-^E		$1,000.00	$1,024.79	$--^D

^A Annualized expense ratio reflects expenses net of applicable fee waivers.

^B Expenses are equal to the Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

^C Amount represents less than .005%.

^D Amount represents less than $.005.

^E 5% return per year before expenses

Distributions (Unaudited)

The fund hereby designates as a capital gain dividend with respect to the taxable year ended April 30, 2019, $159,923, or, if subsequently determined to be different, the net capital gain of such year.

The fund designates 55% and 54% of the dividends distributed in June and December 2018, respectively during the fiscal year as qualifying for the dividends–received deduction for corporate shareholders.

The fund designates 59% and 57% of the dividends distributed in June and December 2018, respectively during the fiscal year as amounts which may be taken into account as a dividend for the purposes of the maximum rate under section 1(h)(11) of the Internal Revenue Code.

The fund will notify shareholders in January 2020 of amounts for use in preparing 2019 income tax returns.

Management's Discussion of Fund Performance

Comments from the Geode Capital Management, LLC, passive equity index team: For the fiscal year, the fund performed roughly in line with the 4.61% gain of the benchmark Russell 2000^® Index. Many top individual contributors this period came from the information technology sector – the strongest-performing sector in the index, led by Trade Desk (+333%). Shares of this online advertising marketplace continued to gain sharply as the company repeatedly reported better-than-expected financial results. Other technology-sector contributors included semiconductor-related companies Cree (+77%) and Integrated Device Tech (+76%), which was no longer held at period end, and software businesses Hubspot (+74%) and Coupa Software (+123%). Elsewhere, strong financial performance lifted shares of Etsy (+126%), an e-commerce web site, as well as discount retailer Five Below (+107%). In contrast, shares of biotechnology company Nektar Therapeutics (-37%), which was no longer held at period end, fell sharply early in the period, in response to an unfavorable drug trial result. Shares of Stamps.com (-62%) struggled after the company terminated an important contract with the U.S. Postal Service. Also detracting was energy services company McDermott International (-57%).

Note to Shareholders: On March 22, 2019, Pat Waddell retired and is no longer a portfolio manager with Geode Capital Management.

Notes to Financial Statements

For the period ended April 30, 2019

1. Organization.

Fidelity Flex Small Cap Index Fund (the Fund) is a fund of Fidelity Salem Street Trust (the Trust) and is authorized to issue an unlimited number of shares. Share transactions on the Statement of Changes in Net Assets may contain exchanges between affiliated funds. 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. The Fund is available only to certain fee-based accounts offered by Fidelity.

2. Investments in Fidelity Central Funds.

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

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 the Fund's investments to the Fair Value Committee (the Committee) established by the Fund's investment adviser. In accordance with valuation policies and procedures approved by the Board, the 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 the 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 the Fund's investments and ratifies the fair value determinations of the Committee.

The 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 – 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 the Fund's investments by major category are as follows:

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.

Foreign Currency. The Fund 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.

Book-tax differences are primarily due to futures contracts, foreign currency transactions, passive foreign investment companies (PFIC), market discount 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:

Gross unrealized appreciation	$9,493,294
Gross unrealized depreciation	(7,462,268)
Net unrealized appreciation (depreciation)	$2,031,026
Tax Cost	$74,576,040

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

Undistributed ordinary income	$289,188
Net unrealized appreciation (depreciation) on securities and other investments	$2,031,026

The tax character of distributions paid was as follows:

	April 30, 2019	April 30, 2018
Ordinary Income	$1,183,443	$ 41,003
Long-term Capital Gains	40,927	477
Total	$1,224,370	$ 41,480

New Rule Issuance. During August 2018, the U.S. Securities and Exchange Commission issued Final Rule Release No. 33-10532, Disclosure Update and Simplification. This Final Rule includes amendments specific to registered investment companies that are intended to eliminate overlap in disclosure requirements between Regulation S-X and GAAP. In accordance with these amendments, certain line-items in the Fund's financial statements have been combined or removed for the current period as outlined in the table below.

Financial Statement	Current Line-Item Presentation (As Applicable)	Prior Line-Item Presentation (As Applicable)
Statement of Assets and Liabilities	Total distributable earnings (loss)	Undistributed/Distributions in excess of/Accumulated net investment income (loss) Accumulated/Undistributed net realized gain (loss) Net unrealized appreciation (depreciation)
Statement of Changes in Net Assets	N/A - removed	Undistributed/Distributions in excess of/Accumulated net investment income (loss) end of period
Statement of Changes in Net Assets	Distributions to shareholders	Distributions to shareholders from net investment income Distributions to shareholders from net realized gain

4. Derivative Instruments.

The Fund's use of derivatives increased or decreased its exposure to the following risk:

Equity Risk

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. The Fund used futures contracts to manage its exposure to the stock market.

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. Cash deposited to meet initial margin requirements is presented as segregated cash with brokers for derivative instruments in the Statement of Assets and Liabilities.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $36,973,970 and $13,862,556, respectively.

6. Fees and Other Transactions with Affiliates.

Prior Fiscal Year Exchanges In-Kind. During the prior period, an affiliated entity completed an exchange in-kind with the Fund. The affiliated entity delivered investments and cash valued at $23,567,263 in exchange for 2,052,897 shares of the Fund. The amount of in kind exchanges is included in share transactions in the accompanying Statement of Changes in Net Assets. The Fund recognized no gain or loss for federal income tax purposes.

7. Committed Line of Credit.

The Fund participates 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 Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $153 and is reflected in Commitment fees on the Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The Fund or borrower may terminate the loan at any time, and if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Fund may apply collateral received from the borrower against the obligation. The Fund may experience delays and costs in recovering the securities loaned. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. The value of securities loaned to FCM at period end was $40,984. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds, and includes $1,438 from securities loaned to FCM.

9. Expense Reductions.

10. Other.

Report of Independent Registered Public Accounting Firm

To the Trustees of Fidelity Salem Street Trust and Shareholders of Fidelity Flex Small Cap Index Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Fidelity Flex Small Cap Index Fund (the "Fund"), a fund of Fidelity Salem Street Trust, including the schedule of investments, as of April 30, 2019, the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the two years in the period then ended and for the period from March 9, 2017 (commencement of operations) to April 30, 2017, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of April 30, 2019, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the two years in the period then ended and for the period from March 9, 2017 (commencement of operations) to April 30, 2017 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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 Fund is not required to have, nor were we engaged to perform, an audit of its 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 Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

/s/ Deloitte & Touche LLP

Boston, Massachusetts

June 18, 2019

We have served as the auditor of one or more of the Fidelity investment companies since 1999.

Trustees and Officers

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust. Each Trustee who is not an interested person (as defined in the 1940 Act) of the trust and the fund is referred to herein as an Independent Trustee. Each Independent Trustee shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs. 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.

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 the 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 fund, 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 fund. 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. Arthur E. Johnson 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.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the 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 at the beginning of the period and held for the entire period (November 1, 2018 to April 30, 2019).

Actual Expenses

Hypothetical Example for Comparison Purposes

	Annualized Expense Ratio-^A	Beginning Account Value November 1, 2018	Ending Account Value April 30, 2019	Expenses Paid During Period-^B November 1, 2018 to April 30, 2019
Actual	- %-^C	$1,000.00	$1,060.90	$--^D
Hypothetical-^E		$1,000.00	$1,024.79	$--^D

^A Annualized expense ratio reflects expenses net of applicable fee waivers.

^B Expenses are equal to the Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

^C Amount represents less than .005%.

^D Amount represents less than $.005.

^E 5% return per year before expenses

Distributions (Unaudited)

The fund hereby designates as a capital gain dividend with respect to the taxable year ended April 30, 2019, $34,552, or, if subsequently determined to be different, the net capital gain of such year.

The fund designates 28% and 32% of the dividends distributed in June and December, respectively during the fiscal year as qualifying for the dividends–received deduction for corporate shareholders.

The fund designates 29% and 35% of the dividend distributed in June and December, respectively during the fiscal year as amounts which may be taken into account as a dividend for the purposes of the maximum rate under section 1(h)(11) of the Internal Revenue Code.

The fund will notify shareholders in January 2020 of amounts for use in preparing 2019 income tax returns.

Management's Discussion of Fund Performance

Comments from the Geode Capital Management, LLC, passive equity index team: For the fiscal year, the fund performed roughly in line with the 9.06% gain of the benchmark Russell 1000^® Value Index. The biggest individual contributor was branded consumer goods company Procter & Gamble (+52%), which, in October, reported healthy sales gains and solid earnings in a strong economy. Strong business execution and benefits from the 2017 federal tax reform law lifted shares of Cisco Systems (+30%), which provides networking products and services. Pharmaceutical manufacturer Merck (+38%) produced stronger-than-expected quarterly earnings throughout the period, while shares of broadband and media provider Comcast (+42%) rose as investors appeared to become less concerned about slowing growth in some of its key businesses. Qualcomm (+77%), a maker of digital communication products, gained sharply in April, when the company received a favorable legal settlement in a longstanding licensing dispute. In contrast, the biggest individual detractor was oil-field services company Schlumberger (-35%), which struggled along with the poor-performing energy sector. General Electric (-23%) continued to endure a variety of business challenges, while worries about political momentum for substantial changes to the health care industry weighed on shares of CVS Health (-20%), which operates a variety of health-related businesses.

Note to Shareholders: On March 22, 2019, Pat Waddell retired and is no longer a portfolio manager with Geode Capital Management.

Notes to Financial Statements

For the period ended April 30, 2019

1. Organization.

Fidelity Large Cap Value Index Fund (the Fund) is a fund of Fidelity Salem Street Trust (the Trust) and is 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.

Effective after the close of business November 9, 2018, the Fund's publicly offered shares classes were consolidated into a single share class. The surviving class is Fidelity Large Cap Value Index Fund (formerly Institutional Premium Class). All current fiscal period dollar and share amounts for the classes that closed, which are presented in the Notes to Financial Statements, are for the period May 1, 2018 through November 9, 2018.

2. Investments in Fidelity Central Funds.

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

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 the Fund's investments to the Fair Value Committee (the Committee) established by the Fund's investment adviser. In accordance with valuation policies and procedures approved by the Board, the 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 the 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 the Fund's investments and ratifies the fair value determinations of the Committee.

The 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 – 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 the Fund's investments by major category are as follows:

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 April 30, 2019, is included at the end of the Fund's Schedule of Investments.

Class Allocations and Expenses. Investment income, realized and unrealized capital gains and losses, common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated daily on a pro-rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent and fees incurred. Certain expense reductions may also differ by class. For the reporting period, the allocated portion of income and expenses to each class as a percent of its average net assets may vary due to the timing of recording these transactions in relation to fluctuating net assets of the classes. 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. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. In addition, the Fund claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

Book-tax differences are primarily due to short-term capital gains, futures contracts, foreign currency transactions, partnerships 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:

Gross unrealized appreciation	$227,395,394
Gross unrealized depreciation	(92,064,484)
Net unrealized appreciation (depreciation)	$135,330,910
Tax Cost	$1,960,442,061

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

Undistributed ordinary income	$13,239,091
Undistributed long-term capital gain	$3,619,325
Net unrealized appreciation (depreciation) on securities and other investments	$135,330,910

The tax character of distributions paid was as follows:

	April 30, 2019	April 30, 2018
Ordinary Income	$32,623,104	$ 17,896,843
Long-term Capital Gains	2,605,776	610,643
Total	$35,228,880	$ 18,507,486

New Rule Issuance. During August 2018, the U.S. Securities and Exchange Commission issued Final Rule Release No. 33-10532, Disclosure Update and Simplification. This Final Rule includes amendments specific to registered investment companies that are intended to eliminate overlap in disclosure requirements between Regulation S-X and GAAP. In accordance with these amendments, certain line-items in the Fund's financial statements have been combined or removed for the current period as outlined in the table below.

Financial Statement	Current Line-Item Presentation (As Applicable)	Prior Line-Item Presentation (As Applicable)
Statement of Assets and Liabilities	Total distributable earnings (loss)	Undistributed/Distributions in excess of/Accumulated net investment income (loss) Accumulated/Undistributed net realized gain (loss) Net unrealized appreciation (depreciation)
Statement of Changes in Net Assets	N/A - removed	Undistributed/Distributions in excess of/Accumulated net investment income (loss) end of period
Statement of Changes in Net Assets	Distributions to shareholders	Distributions to shareholders from net investment income Distributions to shareholders from net realized gain
Distributions to Shareholders Note to Financial Statements	Distributions to shareholders	Distributions to shareholders from net investment income Distributions to shareholders from net realized gain

4. Derivative Instruments.

The Fund's use of derivatives increased or decreased its exposure to the following risk:

Equity Risk

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. The Fund used futures contracts to manage its exposure to the stock market.

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. Cash deposited to meet initial margin requirements is presented as segregated cash with brokers for derivative instruments in the Statement of Assets and Liabilities.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $1,180,129,094 and $215,975,165, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee and Expense Contract. Fidelity Management & Research Company (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is based on an annual rate of .035% of the Fund's average net assets. Under the management contract, the investment adviser pays all other fund-level expenses, except the compensation of the independent Trustees and certain other expenses such as interest expense, including commitment fees.

Effective August 1, 2018, the Board approved an amendment to the expense contract. Under the expense contract, the investment adviser pays class-level expenses as necessary so that the total expenses do not exceed .035% of each class' average net assets on an annual basis with certain exceptions. Prior to August 1, 2018 the investment adviser paid class-level expenses as necessary so that the total expenses do not exceed certain amounts of each class' average net assets on an annual basis with certain exceptions, as noted in the following table:

Investor Class	.17%
Premium Class	.05%
Institutional Class	.04%
Fidelity Large Cap Value Index Fund	.035%

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for each class. FIIOC receives transfer agent fees at an annual rate of .21%, .11%, .035% and .015% of class-level average net assets for Investor Class, Premium Class, Institutional Class and Fidelity Large Cap Value Index Fund, respectively. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements.

Effective August 1, 2018, under the amended expense contract, Investor Class, Premium Class, Institutional Class and Fidelity Large Cap Value Index Fund do not pay transfer agent fees. Prior to August 1, 2018, under the expense contract, Investor Class, Premium Class and Institutional Class paid a portion of the transfer agent fees at an annual rate of .135%, .015% and .005% of class-level average net assets, respectively, and Fidelity Large Cap Value Index Fund did not pay transfer agent fees.

For the period, the total transfer agent fees paid by each applicable class were as follows:

	Amount	% of Class-Level Average Net Assets
Investor Class	$2,474	.03
Premium Class	17,926	–^(a)
Institutional Class	2,489	–^(a)
	$22,889

(a) Amount represents less than .005%.

Interfund Lending Program. Pursuant to an Exemptive Order issued by the SEC, the Fund, along with other registered investment companies having management contracts with Fidelity Management & Research Company (FMR) or other affiliated entities of FMR, may participate in an interfund lending program. This program provides an alternative credit facility allowing the funds to borrow from, or lend money to, other participating affiliated funds. At period end, there were no interfund loans outstanding. The Fund's activity in this program during the period for which loans were outstanding was as follows:

Borrower or Lender	Average Loan Balance	Weighted Average Interest Rate	Interest Expense
Borrower	$11,171,500	2.63%	$1,632

7. Committed Line of Credit.

The Fund participates 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 Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $3,553 and is reflected in Commitment fees on the Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The Fund or borrower may terminate the loan at any time, and if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Fund may apply collateral received from the borrower against the obligation. The Fund may experience delays and costs in recovering the securities loaned. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Total security lending income during the period amounted to $45,505. During the period, there were no securities loaned to FCM.

Report of Independent Registered Public Accounting Firm

To the Trustees of Fidelity Salem Street Trust and Shareholders of Fidelity Large Cap Value Index Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Fidelity Large Cap Value Index Fund (the "Fund"), a fund of Fidelity Salem Street Trust, including the schedule of investments, as of April 30, 2019, the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the two years in the period then ended and for the period from June 7, 2016 (commencement of operations) to April 30, 2017, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of April 30, 2019, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the two years in the period then ended and for the period from June 7, 2016 (commencement of operations) to April 30, 2017, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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 Fund is not required to have, nor were we engaged to perform, an audit of its 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 Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

/s/ Deloitte & Touche LLP

Boston, Massachusetts

June 12, 2019

We have served as the auditor of one or more of the Fidelity investment companies since 1999.

Trustees and Officers

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust. Each Trustee who is not an interested person (as defined in the 1940 Act) of the trust and the fund is referred to herein as an Independent Trustee. Each Independent Trustee shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs. 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 fund’s Statement of Additional Information (SAI) includes more information about the Trustees. To request a free copy, call Fidelity at 1-800-544-8544.

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 the 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 fund, 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 fund. 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. Arthur E. Johnson 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.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the 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 at the beginning of the period and held for the entire period (November 1, 2018 to April 30, 2019).

Actual Expenses

Hypothetical Example for Comparison Purposes

	Annualized Expense Ratio-^A	Beginning Account Value November 1, 2018	Ending Account Value April 30, 2019	Expenses Paid During Period-^B November 1, 2018 to April 30, 2019
Fidelity Large Cap Value Index Fund	.04%
Actual		$1,000.00	$1,079.50	$.21
Hypothetical-^C		$1,000.00	$1,024.60	$.20

^A Annualized expense ratio reflects expenses net of applicable fee waivers.

^B Expenses are equal to the Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

^C 5% return per year before expenses

Distributions (Unaudited)

The Board of Trustees of Fidelity Large Cap Value Index Fund voted to pay on June 10, 2019, to shareholders of record at the opening of business on June 7, 2019, a distribution of $0.022 per share derived from capital gains realized from sales of portfolio securities and a dividend of $0.078 per share from net investment income.

The fund hereby designates as a capital gain dividend with respect to the taxable year ended April 30, 2019, $6,305,871, or, if subsequently determined to be different, the net capital gain of such year.

Fidelity Large Cap Value Index Fund designates 90% and 73%; of the dividends distributed in June and December, respectively during the fiscal year as qualifying for the dividends–received deduction for corporate shareholders.

Investor Class designates 100%; Premium Class designates 96%; and Institutional Class designates 95%; of the dividends distributed in June during the fiscal year as amounts which may be taken into account as a dividend for purposes of the maximum rate under section 1(h)(11) of the Internal Revenue Code. Fidelity Large Cap Value Index Fund designates 94% and 78%; of the dividends distributed in June and December, respectively during the fiscal year as amounts which may be taken into account as a dividend for purposes of the maximum rate under section 1(h)(11) of the Internal Revenue Code.

The fund will notify shareholders in January 2020 of amounts for use in preparing 2019 income tax returns.

Management's Discussion of Fund Performance

Comments from the Geode Capital Management, LLC, passive equity index team: For the fiscal year, the fund performed roughly in line with the 17.43% gain of the benchmark Russell 1000^® Growth Index. Within information technology – the strongest-performing sector in the index – several individual stocks were outsized contributors, led by Microsoft (+42%), whose strong financial results and healthy market position in cloud computing lifted the software manufacturer's shares. Consumer electronics maker Apple (+23%) gained ground, partly due to strong growth and profitability in its services business. Payment-processing companies such as Mastercard (+43%), Visa (+30%) and PayPal Holdings (+51%) all continued to benefit from the global trend toward electronic payments. Elsewhere, other notable contributors included online retail giant Amazon.com (+23%) and Alphabet, whose share classes returned roughly 17% to 18%. In contrast, the biggest individual detractor was Nvidia (-19%), a maker of graphics processors. Its shares plunged last fall after the company reported weaker-than-expected earnings. Similarly, a disappointing earnings report weighed on shares of pharmaceutical company AbbVie, which returned -14% for the period. Other detractors included oil-field services company Halliburton (-45%), which struggled along with the poor-performing energy sector, and travel company Booking Holdings, whose weak earnings guidance hampered the stock (-15%).

Note to Shareholders: On March 22, 2019, Pat Waddell retired and is no longer a portfolio manager with Geode Capital Management.

Notes to Financial Statements

For the period ended April 30, 2019

1. Organization.

Fidelity Large Cap Growth Index Fund (the Fund) is a fund of Fidelity Salem Street Trust (the Trust) and is 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.

Effective after the close of business November 9, 2018, the Fund's publicly offered shares classes were consolidated into a single share class. The surviving class is Fidelity Large Cap Growth Index Fund (formerly Institutional Premium Class). All current fiscal period dollar and share amounts for the classes that closed, which are presented in the Notes to Financial Statements, are for the period May 1, 2018 through November 9, 2018.

2. Investments in Fidelity Central Funds.

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

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 the Fund's investments to the Fair Value Committee (the Committee) established by the Fund's investment adviser. In accordance with valuation policies and procedures approved by the Board, the 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 the 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 the Fund's investments and ratifies the fair value determinations of the Committee.

The 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 – 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 the Fund's investments by major category are as follows:

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.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost. Dividend income is recorded on the ex-dividend date. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Certain distributions received by the Fund represent a return of capital or capital gain. The Fund determines the components of these distributions subsequent to the ex-dividend date, based upon receipt of tax filings or other correspondence relating to the underlying investment. These distributions are recorded as a reduction of cost of investments and/or as a realized gain. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable.

Class Allocations and Expenses. Investment income, realized and unrealized capital gains and losses, common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated daily on a pro-rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent fees incurred. Certain expense reductions may also differ by class. For the reporting period, the allocated portion of income and expenses to each class as a percent of its average net assets may vary due to the timing of recording these transactions in relation to fluctuating net assets of the classes. 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. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. In addition, the Fund claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

Book-tax differences are primarily due to futures contracts, market discount, partnerships 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:

Gross unrealized appreciation	$420,603,776
Gross unrealized depreciation	(45,594,821)
Net unrealized appreciation (depreciation)	$375,008,955
Tax Cost	$1,890,131,802

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

Undistributed ordinary income	$7,630,424
Net unrealized appreciation (depreciation) on securities and other investments	$375,008,955

The tax character of distributions paid was as follows:

	April 30, 2019	April 30, 2018
Ordinary Income	$16,665,057	$ 8,601,052
Long-term Capital Gains	1,788,246	308,471
Total	$18,453,303	$ 8,909,523

New Rule Issuance. During August 2018, the U.S. Securities and Exchange Commission issued Final Rule Release No. 33-10532, Disclosure Update and Simplification. This Final Rule includes amendments specific to registered investment companies that are intended to eliminate overlap in disclosure requirements between Regulation S-X and GAAP. In accordance with these amendments, certain line-items in the Fund's financial statements have been combined or removed for the current period as outlined in the table below.

Financial Statement	Current Line-Item Presentation (As Applicable)	Prior Line-Item Presentation (As Applicable)
Statement of Assets and Liabilities	Total distributable earnings (loss)	Undistributed/Distributions in excess of/Accumulated net investment income (loss) Accumulated/Undistributed net realized gain (loss) Net unrealized appreciation (depreciation)
Statement of Changes in Net Assets	N/A - removed	Undistributed/Distributions in excess of/Accumulated net investment income (loss) end of period
Statement of Changes in Net Assets	Distributions to shareholders	Distributions to shareholders from net investment income Distributions to shareholders from net realized gain
Distributions to Shareholders Note to Financial Statements	Distributions to shareholders	Distributions to shareholders from net investment income Distributions to shareholders from net realized gain

4. Derivative Instruments.

The Fund's use of derivatives increased or decreased its exposure to the following risk:

Equity Risk

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. The Fund used futures contracts to manage its exposure to the stock market.

5. Purchases and Sales of Investments.

6. Fees and Other Transactions with Affiliates.

Investor Class	.17%
Premium Class	.05%
Institutional Class	.04%
Fidelity Large Cap Growth Index Fund	.035%

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for each class. FIIOC receives transfer agent fees at an annual rate of .21%, .11%, .035% and .015% of class-level average net assets for Investor Class, Premium Class, Institutional Class and Fidelity Large Cap Growth Index Fund, respectively. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements.

Effective August 1, 2018, under the amended expense contract, Investor Class, Premium Class, Institutional Class and Fidelity Large Cap Growth Index Fund do not pay transfer agent fees. Prior to August 1, 2018, under the expense contract, Investor Class, Premium Class and Institutional Class paid a portion of the transfer agent fees at an annual rate of .135%, .015% and .005% of class-level average net assets, respectively, and Fidelity Large Cap Growth Index Fund did not pay transfer agent fees.

For the period, the total transfer agent fees paid by each applicable class were as follows:

	Amount	% of Class-Level Average Net Assets
Investor Class	$6,068	.03
Premium Class	24,561	–^(a)
Institutional Class	2,702	–^(a)
	$33,331

(a) Less than .005%

7. Committed Line of Credit.

The Fund participates 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 Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $3,677 and is reflected in Commitment fees on the Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The Fund or borrower may terminate the loan at any time, and if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Fund may apply collateral received from the borrower against the obligation. The Fund may experience delays and costs in recovering the securities loaned. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Total security lending income during the period amounted to $125,724. During the period, there were no securities loaned to FCM.

Report of Independent Registered Public Accounting Firm

To the Trustees of Fidelity Salem Street Trust and Shareholders of Fidelity Large Cap Growth Index Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Fidelity Large Cap Growth Index Fund (the "Fund"), a fund of Fidelity Salem Street Trust, including the schedule of investments, as of April 30, 2019, the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the two years in the period then ended and for the period from June 7, 2016 (commencement of operations) to April 30, 2017, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of April 30, 2019, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the two years in the period then ended and for the period from June 7, 2016 (commencement of operations) to April 30, 2017 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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 Fund is not required to have, nor were we engaged to perform, an audit of its 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 Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

/s/ Deloitte & Touche LLP

Boston, Massachusetts

June 12, 2019

We have served as the auditor of one or more of the Fidelity investment companies since 1999.

Trustees and Officers

The Trustees, Members of the Advisory Board (if any), and officers of the trust and fund, as applicable, are listed below. The Board of Trustees governs the fund and is responsible for protecting the interests of shareholders. The Trustees are experienced executives who meet periodically throughout the year to oversee the fund's activities, review contractual arrangements with companies that provide services to the fund, oversee management of the risks associated with such activities and contractual arrangements, and review the fund's performance. Except for Jonathan Chiel each of the Trustees oversees 264 funds. Mr. Chiel oversees 158 funds.

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust. Each Trustee who is not an interested person (as defined in the 1940 Act) of the trust and the fund is referred to herein as an Independent Trustee. Each Independent Trustee shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs. 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 fund’s Statement of Additional Information (SAI) includes more information about the Trustees. To request a free copy, call Fidelity at 1-800-544-8544.

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 the 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 fund, 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 fund. 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. Arthur E. Johnson 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.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the 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 at the beginning of the period and held for the entire period (November 1, 2018 to April 30, 2019).

Actual Expenses

Hypothetical Example for Comparison Purposes

	Annualized Expense Ratio-^A	Beginning Account Value November 1, 2018	Ending Account Value April 30, 2019	Expenses Paid During Period-^B November 1, 2018 to April 30, 2019
Fidelity Large Cap Growth Index Fund	.03%
Actual		$1,000.00	$1,120.10	$.16
Hypothetical-^C		$1,000.00	$1,024.65	$.15

^A Annualized expense ratio reflects expenses net of applicable fee waivers.

^B Expenses are equal to the Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

^C 5% return per year before expenses

Distributions (Unaudited)

The fund hereby designates as a capital gain dividend with respect to the taxable year ended April 30, 2019, $2,592,382, or, if subsequently determined to be different, the net capital gain of such year.

Investor Class designates 84%; Premium Class designates 72%; and Institutional Class designates 72%; of the dividend distributed in June during the fiscal year as qualifying for the dividends-received deduction for corporate shareholders. Fidelity Large Cap Growth Index Fund designates 71% and 91%; of the dividends distributed in June and December, respectively during the fiscal year as qualifying for the dividends–received deduction for corporate shareholders.

Investor Class designates 86%; Premium Class designates 74%; and Institutional Class designates 73%; of the dividend distributed in June during the fiscal year as amounts which may be taken into account as a dividend for purposes of the maximum rate under section 1(h)(11) of the Internal Revenue Code. Fidelity Large Cap Growth Index Fund designates 73% and 95%; of the dividends distributed in June and December, respectively during the fiscal year as amounts which may be taken into account as a dividend for purposes of the maximum rate under section 1(h)(11) of the Internal Revenue Code.

The fund will notify shareholders in January 2020 of amounts for use in preparing 2019 income tax returns.

Management's Discussion of Fund Performance

Comments from the Geode Capital Management, LLC, passive equity index team: Between the fund's August 17, 2018, inception date and April 30, 2019, the fund performed roughly in line with the 5.88% gain of the benchmark Russell 1000^® Growth Index. The information technology category was home to several top contributors, led by Microsoft (+23%), whose strong financial results and healthy market position in cloud computing lifted the software manufacturer's shares. Payment-processing companies such as Mastercard (+25%), Visa (+16%) and PayPal Holdings (+31%) all continued to benefit from the global trend toward electronic payments. Elsewhere, social-networking leader Facebook (+12%) saw its shares rise on stronger-than-expected sales and earnings, as did coffee giant Starbucks (+46%). The biggest individual detractor this period was consumer electronics and personal computer maker Apple, the largest position in the index. Its shares returned -6%, partly reflecting investors' concern about slowing mobile phone sales. Another detractor was Nvidia (-27%), a maker of graphics processors. Its shares plunged last fall after the company reported weaker-than-expected earnings. Similarly, a disappointing earnings report weighed on shares of pharmaceutical company AbbVie, which returned -16% for the period. Health insurer UnitedHealth Group (-10%) also detracted.

Note to Shareholders: On March 22, 2019, Pat Waddell retired and is no longer a portfolio manager with Geode Capital Management.

Notes to Financial Statements

For the period ended April 30, 2019

1. Organization.

Fidelity Series Large Cap Growth Index Fund (the Fund) is a fund of Fidelity Salem Street Trust (the Trust) and is authorized to issue an unlimited number of shares. Shares of the Fund are only available for purchase by mutual funds for which Fidelity Management & Research Company (FMR) or an affiliate serves as an investment manager. 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.

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

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 the Fund's investments to the Fair Value Committee (the Committee) established by the Fund's investment adviser. In accordance with valuation policies and procedures approved by the Board, the 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 the 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 the Fund's investments and ratifies the fair value determinations of the Committee.

The 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 – 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 the Fund's investments by major category are as follows:

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.

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 futures contracts, partnerships 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:

Gross unrealized appreciation	$12,627,969
Gross unrealized depreciation	(2,939,071)
Net unrealized appreciation (depreciation)	$9,688,898
Tax Cost	$254,875,263

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

Undistributed ordinary income	$271,712
Undistributed long-term capital gain	$23,956
Net unrealized appreciation (depreciation) on securities and other investments	$9,688,898

The tax character of distributions paid was as follows:

	April 30, 2019^(a)
Ordinary Income	$29,337

(a) For the period August 17, 2018 (commencement of operations) to April 30, 2019.

4. Derivative Instruments.

The Fund's use of derivatives increased or decreased its exposure to the following risk:

Equity Risk

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. The Fund used futures contracts to manage its exposure to the stock market.

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. Cash deposited to meet initial margin requirements is presented as segregated cash with brokers for derivative instruments in the Statement of Assets and Liabilities.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $258,776,517 and $5,650,396, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund does not pay a management fee. Under the management contract, the investment adviser or an affiliate pays all ordinary operating expenses of the Fund, except custody fees, fees and expenses of the independent Trustees, and certain miscellaneous expenses such as proxy and shareholder meeting expenses.

7. Committed Line of Credit.

The Fund participates 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 Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $3 and is reflected in Commitment fees on the Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Expense Reductions.

The investment adviser contractually agreed to reimburse the Fund to the extent annual operating expenses exceeded .014% of average net assets. This reimbursement will remain in place through August 31, 2022. Some expenses, for example the compensation of the independent Trustees, and certain miscellaneous expenses such as proxy and shareholder meeting expenses, are excluded from this reimbursement. During the period this reimbursement reduced the Fund's expenses by $9,297.

9. Other.

At the end of the period, mutual funds managed by the investment adviser or its affiliates were the owners of record of all of the outstanding shares of the Fund.

Report of Independent Registered Public Accounting Firm

To the Trustees of Fidelity Salem Street Trust and Shareholders of Fidelity Series Large Cap Growth Index Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Fidelity Series Large Cap Growth Index Fund (the "Fund"), a fund of Fidelity Salem Street Trust, including the schedule of investments, as of April 30, 2019, the related statement of operations, the statement of changes in net assets and the financial highlights for the period from August 17, 2018 (commencement of operations) to April 30, 2019, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of April 30, 2019, and the results of its operations, the changes in its net assets and the financial highlights for the period from August 17, 2018 (commencement of operations) to April 30, 2019 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 Fund's management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audit. 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 Fund 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 audit 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 Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit 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 Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit 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 audit 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 April 30, 2019, by correspondence with the custodians and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audit provides a reasonable basis for our opinion.

Boston, Massachusetts

June 18, 2019

We have served as the auditor of one or more of the Fidelity investment companies since 1999.

Trustees and Officers

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust. Each Trustee who is not an interested person (as defined in the 1940 Act) of the trust and the fund is referred to herein as an Independent Trustee. Each Independent Trustee shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs. 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 fund’s Statement of Additional Information (SAI) includes more information about the Trustees. To request a free copy, call Fidelity at 1-800-544-8544.

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 the 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 fund, 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 fund. 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. Arthur E. Johnson 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.

Hypothetical-^C		$1,000.00	$1,024.74	$.05

^A Annualized expense ratio reflects expenses net of applicable fee waivers.

^C 5% return per year before expenses

Distributions (Unaudited)

The Board of Trustees of Fidelity Series Large Cap Growth Index Fund voted to pay on June 10, 2019, to shareholders of record at the opening of business on June 07, 2019, a distribution of $.005 per share derived from capital gains realized from sales of portfolio securities and a dividend of $.008 per share from net investment income.

The fund hereby designates as a capital gain dividend with respect to the taxable year ended April 30, 2019, $23,956, or, if subsequently determined to be different, the net capital gain of such year.

The fund designates 87% of the dividends distributed during the fiscal year as qualifying for the dividends–received deduction for corporate shareholders.

The fund designates 89% of the dividends distributed during the fiscal year as amounts which may be taken into account as a dividend for the purposes of the maximum rate under section 1(h)(11) of the Internal Revenue Code.

The fund will notify shareholders in January 2020 of amounts for use in preparing 2019 income tax returns.

The trust's Audit Committee has considered non-audit services that were not pre-approved that were provided by Deloitte Entities to Fund Service Providers to be compatible with maintaining the independence of Deloitte Entities in its audit of the Funds, taking into account representations from Deloitte Entities, in accordance with Public Company Accounting Oversight Board rules, regarding its independence from the Funds and their related entities and FMR’s review of the appropriateness and permissibility under applicable law of such non-audit services prior to their provision to the Fund Service Providers.

Audit Committee Pre-Approval Policies and Procedures

The trust’s Audit Committee must pre-approve all audit and non-audit services provided by a fund’s independent registered public accounting firm relating to the operations or financial reporting of the fund. Prior to the commencement of any audit or non-audit services to a fund, the Audit Committee reviews the services to determine whether they are appropriate and permissible under applicable law.

The Audit Committee has adopted policies and procedures to, among other purposes, provide a framework for the Committee’s consideration of non-audit services by the audit firms that audit the Fidelity funds. The policies and procedures require that any non-audit service provided by a fund audit firm to a Fidelity fund and any non-audit service provided by a fund auditor to a Fund Service Provider that relates directly to the operations and financial reporting of a Fidelity fund (“Covered Service”) are subject to approval by the Audit Committee before such service is provided.

All Covered Services must be approved in advance of provision of the service either: (i) by formal resolution of the Audit Committee, or (ii) by oral or written approval of the service by the Chair of the Audit Committee (or if the Chair is unavailable, such other member of the Audit Committee as may be designated by the Chair to act in the Chair’s absence). The approval contemplated by (ii) above is permitted where the Treasurer determines that action on such an engagement is necessary before the next meeting of the Audit Committee.

Non-audit services provided by a fund audit firm to a Fund Service Provider that do not relate directly to the operations and financial reporting of a Fidelity fund are reported to the Audit Committee periodically.

Non-Audit Services Approved Pursuant to Rule 2-01(c)(7)(i)(C) and (ii) of Regulation S-X (“De Minimis Exception”)

There were no non-audit services approved or required to be approved by the Audit Committee pursuant to the De Minimis Exception during the Funds’ last two fiscal years relating to services provided to (i) the Funds or (ii) any Fund Service Provider that relate directly to the operations and financial reporting of the Funds.
