Note to Shareholders:

Early in 2020, the outbreak and spread of COVID-19 emerged as a public health emergency that had a major influence on financial markets, primarily based on its impact on the global economy and corporate earnings. On March 11, 2020, the World Health Organization declared the COVID-19 outbreak a pandemic, citing sustained risk of further global spread. The pandemic prompted a number of measures to limit the spread of COVID-19, including travel and border restrictions, quarantines, and restrictions on large gatherings. In turn, these resulted in lower consumer activity, diminished demand for a wide range of products and services, disruption in manufacturing and supply chains, and – given the wide variability in outcomes regarding the outbreak – significant market uncertainty and volatility. To help stem the turmoil, the U.S. government took unprecedented action – in concert with the U.S. Federal Reserve and central banks around the world – to help support consumers, businesses, and the broader economy, and to limit disruption to the financial system.

In general, the overall impact of the pandemic lessened in 2021, amid a resilient economy and widespread distribution of three COVID-19 vaccines granted emergency use authorization from the U.S. Food and Drug Administration (FDA) early in the year. Still, the situation remains dynamic, and the extent and duration of its influence on financial markets and the economy is highly uncertain, due in part to a recent spike in cases based on highly contagious variants of the coronavirus.

Extreme events such as the COVID-19 crisis are exogenous shocks that can have significant adverse effects on mutual funds and their investments. Although multiple asset classes may be affected by market disruption, the duration and impact may not be the same for all types of assets. Fidelity is committed to helping you stay informed amid news about COVID-19 and during increased market volatility, and we continue to take extra steps to be responsive to customer needs. We encourage you to visit us online, where we offer ongoing updates, commentary, and analysis on the markets and our funds.

Fidelity® Disruptive Automation 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: Global equities returned -6.49% for the 12 months ending May 31, 2022, according to the MSCI ACWI (All Country World Index) Index. After posting an 18.90% gain in 2021, global stocks retreated to begin the new year amid several headwinds that stoked volatility, uncertainty and investor anxiety. Chief among these was accelerated efforts by some central banks to hike interest rates and aggressively wind down extraordinary monetary policy support in an attempt to rein in high inflation. In addition, geopolitical unrest rose as Russia invaded Ukraine in late February and escalated its attack through period end. Other factors influencing stocks included surging global commodity prices, rising sovereign bond yields in some markets, global supply constraint and disruption, and the potential for variants of the coronavirus to upend global economic growth. Against this backdrop, the index returned -4.90% in January and -2.56% in February, falling on mixed corporate earnings. Volatility eased in March and the index gained 2.21% for the month. April saw a reversal (-7.98%), amid angst about the economic toll of “zero-COVID” lockdowns in China, and then the index had a flattish May (+0.16%). For the full 12 months, emerging markets (-20%) lagged most, followed by Japan (-13%) and Europe ex U.K. (-12%). Conversely, the U.K. and Canada (+3%) led. By sector, communication services (-23%) and consumer discretionary (-21%) fared worst, whereas energy (+48%) rode a surge in commodity prices and topped the market by a wide margin.

Comments from Co-Managers Charlie Hebard and Christopher Lee: For the fiscal year ending May 31, 2022, the fund's share classes returned roughly -17% to -16%, underperforming the -10.14% return of the MSCI All Country World Industrials Equal Weighted Index Net MA, as well as the broad-based MSCI All Country World Index (Net MA). By region, stock picks in emerging markets, specifically Taiwan and Japan, hurt the fund's relative result. By industry, the primary detractors from performance versus the benchmark were an overweighting and stock selection in industrial machinery. Weak picks in electronic equipment & instruments also hurt. Also hurting performance was an underweighting in aerospace & defense. The biggest individual relative detractor was an overweight position in Hiwin Technologies (-40%). Another notable relative detractor was an overweighting in Misumi Group (-30%). This period we increased our stakes in both Hiwin and Musimi. The fund's non-benchmark stake in Renishaw, one of our largest holdings as of May 31, returned -34%. Conversely, stock picks in the U.S. and an underweighting in Europe ex U.K., specifically Netherlands, contributed most to the fund's relative result. By industry, the primary contributor to performance versus the benchmark was security selection in semiconductors. An underweighting in construction machinery & heavy trucks also bolstered the fund's relative performance. Also lifting the fund's relative result was an underweighting in building products. Nvidia, the fund's largest individual contributor, rose roughly 14% this period. We reduced our stake in the company the past twelve months. Our second-largest contributor was Synopsys, which gained approximately 25% the past year. Another contributor this period was Microsoft. The shares gained 10% the past twelve months. All these contributors were non-benchmark positions.

Fidelity® Disruptive Communications Fund

Management's Discussion of Fund Performance

Comments from Co-Managers Charlie Hebard and Christopher Lee: For the fiscal year ending May 31, 2022, the fund's share classes returned roughly -28%, trailing the -18.71% result of the MSCI All Country World Communication Services Equal Weighted Index Net MA, as well as the broad-based MSCI All Country World Index (Net MA). By region, an overweighting in the U.S. and stock picks and an underweighting in Asia Pacific ex Japan, primarily driven by Singapore, detracted from the fund's relative result. By industry, the largest detractor from performance versus the benchmark was an underweighting in integrated telecommunication services. Weak picks in application software also hurt. Also hurting performance were stock picks in interactive home entertainment. The fund's biggest individual relative detractor was an outsized stake in Snap, which returned about -77% the past twelve months. We increased our position in this company. Also hindering performance was our overweighting in Sea, which returned roughly -68%. We added to our stake the past year. The fund's non-benchmark stake in Zoom Video Communications, a position not held at period end, returned roughly -69%. In contrast, stock picks in the U.S. contributed most to the fund's relative result. By industry, the top contributor to performance versus the benchmark was stock selection in internet services & infrastructure. An underweighting in movies & entertainment also lifted the fund's relative result. Also helping the fund's relative result were stock picks in communications equipment. Our non-benchmark stake in Cloudflare was the fund's biggest individual relative contributor, despite a 12-month result of approximately -32%; we decreased our position in the company at the right time to lock in earlier gains. The fund's non-benchmark stake in Arista Networks, one of the fund's largest holdings, gained 20%. Another notable relative contributor was an outsized stake in T-Mobile (-6%), which was our biggest holding.

Fidelity® Disruptive Finance Fund

Management's Discussion of Fund Performance

Comments from Co-Managers Charlie Hebard and Christopher Lee: For the fiscal year ending May 31, 2022, the fund's share classes returned roughly -15% to -14%, underperforming the -6.93% return of the MSCI All Country World Financials Equal Weighted Index (Net MA), as well as the broad-based MSCI All Country World Index (Net MA). By region, an overweighting and stock picks in the U.S. and security selection in Europe ex U.K., specifically Netherlands, hindered the fund's relative result. By industry, the primary detractor from performance versus the benchmark was our stock selection in data processing & outsourced services. An underweighting in diversified banks also hindered the fund's relative result. Also hindering our result was stock selection in real estate services. PayPal Holdings, the fund's biggest individual detractor, returned roughly -68% this period. Our second-largest detractor was Doma Holdings, which returned about -69% the past 12 months. This was a position we established during the period. Another detractor was Block, which returned approximately -62% the past twelve months. This was a position we established the past year. All these detractors were non-benchmark positions. Conversely, an underweighting in Europe ex U.K. and Asia Pacific ex Japan, specifically Hong Kong, contributed most to the fund's relative result. By industry, the primary contributors to performance versus the benchmark were an underweighting and security selection in investment banking & brokerage. Security selection in consumer finance and an overweighting in insurance brokers also bolstered the fund's relative performance. The biggest individual relative contributor was an overweight position in Arch Capital Group (+19%). Arch Capital was among the fund's largest holdings. Also adding value was our outsized stake in Apollo Asset Management, which gained about 28%. Apollo was not held at period end. Another notable relative contributor was an overweighting in Arthur J Gallaghar (+12%), which was one of the fund's biggest holdings.

Management's Discussion of Fund Performance

Comments from Co-Managers Charlie Hebard and Christopher Lee: For the fiscal year ending May 31, 2022, the fund's share classes returned about -23% to -22%, outperforming the -23.79% result of the MSCI All Country World Health Care Equal Weighted Index (Net MA), but underperforming the broad-based MSCI All Country World Index (Net MA). By region, an overweighting in the U.S. and an underweighting in emerging markets, primarily driven by China, contributed most to the fund's relative result. By industry, the top contributors to performance versus the benchmark were an overweighting and stock selection in managed health care. Security selection in pharmaceuticals and an underweighting in health care supplies also helped. The fund's largest individual relative contributor was an outsized stake in UnitedHealth Group, which gained 22% the past year. The company was among our largest holdings. Also bolstering performance was an overweighting in Regeneron Pharmaceuticals, which gained about 32%. Regeneron Pharmaceuticals was among our biggest holdings. Another notable relative contributor was an outsized stake in Centene (+11%), which was one of our largest holdings. In contrast, stock picks in the U.S. and an underweighting in Japan hindered the fund's relative result. By industry, the largest detractor from performance versus the benchmark was an underweighting in pharmaceuticals. Stock picks and an overweighting in biotechnology and security selection in health care services also hindered relative performance. The fund's biggest individual relative detractor was an overweighting in 10x Genomics, which returned -72% the past twelve months. We added to our stake in this company. The fund's non-benchmark stake in TG Therapeutics returned approximately -87%. The fund's stake in Mirati Therapeutics, a non-benchmark position we established this period, returned -67%.

Fidelity® Disruptive Technology Fund

Management's Discussion of Fund Performance

Comments from Co-Managers Charlie Hebard and Christopher Lee: For the fiscal year ending May 31, 2022, the fund's share classes returned roughly -34% to -33%, underperforming the -17.58% return of the MSCI All Country World Information Technology Equal Weighted Index (Net MA), as well as the broad-based MSCI All Country World Index (Net MA). By region, stock picks in the U.S. and emerging markets hurt the fund's relative result. By industry, the primary detractor from performance versus the benchmark was our stock picks in interactive media & services. Weak picks in internet & direct marketing retail also hampered the fund's relative result. Also detracting from performance was security selection in movies & entertainment. Sea, the fund's top individual detractor, returned approximately -70% this period. This was a position we established the past twelve months. Our second-largest detractor was Netflix, which returned roughly -61% the past year. This was among the fund's biggest holdings this period. Another detractor this period was Yandex. The stock returned -95% the past twelve months. All these detractors were non-benchmark positions. Conversely, an underweighting in emerging markets, specifically China, and an overweighting in the U.S. contributed most to the fund's relative result. By industry, the primary contributor to performance versus the benchmark was stock selection in systems software. Strong picks in internet services & infrastructure also helped. Also boosting the fund's relative performance was stock selection in wireless telecommunication services. The biggest individual relative contributor was an overweight position in Microsoft (+11%), the fund's largest holding. Also bolstering performance was our overweighting in Nvidia, which gained 18%. Nvidia was among the fund's largest holdings the past twelve months. The fund's non-benchmark stake in Alphabet, one of the fund's biggest holdings, returned about -4% and notably contributed.

The information used in the above reconciliation represents fiscal year to date activity for any Investments in Securities identified as using Level 3 inputs at either the beginning or the end of the current fiscal period. Transfers into Level 3 were attributable to a lack of observable market data resulting from decreases in market activity, decreases in liquidity, security restructurings or corporate actions. Transfers out of Level 3 were attributable to observable market data becoming available for those securities. Cost of purchases and proceeds of sales may include securities received and/or delivered through in-kind transactions. Transfers in or out of Level 3 represent the beginning value of any Security or Instrument where a change in the pricing level occurred from the beginning to the end of the period. The cost of purchases and the proceeds of sales may include securities received or delivered through corporate actions or exchanges. Realized and unrealized gains (losses) disclosed in the reconciliation{s} are included in Net Gain (Loss) on the Fund's Statement of Operations.

For certain accounts, Fidelity Disruptive Fund shares will automatically convert to Loyalty Class 1 shares after a holding period of one year from the initial date of purchase; and then from Loyalty Class 1 shares to Loyalty Class 2 shares after another holding period of two years. Investments in emerging markets, if applicable, can be subject to social, economic, regulatory, and political uncertainties and can be extremely volatile.

2. Investments in Fidelity Central Funds.

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

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

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

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

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

3. Significant Accounting Policies.

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

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

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

Level 1 – unadjusted quoted prices in active markets for identical investments
Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

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

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.

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 May 31, 2022, as well as a roll forward of Level 3 investments, is included at the end of each Fund's Schedule of Investments.

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

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

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

Investment Transactions and Income. For financial reporting purposes, 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. Commissions paid to certain brokers with whom the investment adviser, or its affiliates, places trades on behalf of a fund include an amount in addition to trade execution, which may be rebated back to a fund. Any such rebates are included in net realized gain (loss) on investments in the Statement of Operations. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Funds are informed of the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. 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. Funds may file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld. Any withholding tax reclaims income is included in the Statement of Operations in dividends or foreign taxes withheld, as applicable. Any receivables for withholding tax reclaims are included in the Statement of Assets and Liabilities in dividends receivable.

Class Allocations and Expenses. Investment income, realized and unrealized capital gains and losses, common expenses of a 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 a fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred, as applicable. Certain expense reductions may also differ by class, if applicable. 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. Expenses included in the accompanying financial statements reflect the expenses of that fund and do not include any expenses associated with any underlying mutual funds or exchange-traded funds. Although not included in a fund's expenses, a fund indirectly bears its proportionate share of these expenses through the net asset value of each underlying mutual fund or exchange-traded fund. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, each Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. As of May 31, 2022, each Fund did not have any unrecognized tax benefits in the financial statements; nor is each Fund aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. Each Fund files a U.S. federal tax return, in addition to state and local tax returns as required. Each Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction. 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, certain 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 foreign currency transactions, passive foreign investment companies (PFIC), net operating losses, capital loss carryforwards and losses deferred due to wash sales and excise tax regulations.

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

	Tax cost	Gross unrealized appreciation	Gross unrealized depreciation	Net unrealized appreciation (depreciation)

5. Fees and Other Transactions with Affiliates.

Management Fee and Expense Contract. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide each Fund with investment management related services for which each Class of each Fund pays a monthly all-inclusive management fee based on an annual percentage of class-level average net assets. Under the management contract, the investment adviser pays all other operating expenses, except the compensation of the independent Trustees and certain miscellaneous expenses, such as proxy and shareholder meeting expenses.

Under the expense contract, the investment adviser pays all other class-level operating expenses as necessary, except the compensation of the independent Trustees and certain miscellaneous expenses, such as proxy and shareholder meeting expenses, so that total expenses of Loyalty Class 1, Loyalty Class 2 and Class F do not exceed an annual percentage of class-level average net assets.

For the reporting period, the annual management fee and expense contract rates were as follows:

	Management Fee Annual % of Class-Level Average Net Assets	Expense Contract Annual % of Class-Level Average Net Assets

6. 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 Miscellaneous expenses on the Statement of Operations, and are listed below. During the period, there were no borrowings on this line of credit.

7. Security Lending.

Funds lend portfolio securities from time to time in order to earn additional income. Lending agents are used, including National Financial Services (NFS), an affiliate of the investment adviser. Pursuant to a securities lending agreement, NFS will receive a fee, which is capped at 9.9% of a fund's daily lending revenue, for its services as lending agent. A fund may lend securities to certain qualified borrowers, including NFS. On the settlement date of the loan, a 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 a fund and any additional required collateral is delivered to a fund on the next business day. A 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, a fund may apply collateral received from the borrower against the obligation. A 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. Any loaned securities are identified as such in the Schedule of Investments, and the value of loaned securities and cash collateral at period end, as applicable, are presented in the 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. Affiliated security lending activity, if any, was as follows:

	Total Security Lending Fees Paid to NFS	Security Lending Income From Securities Loaned to NFS	Value of Securities Loaned to NFS at Period End
Fidelity Disruptive Automation Fund	$197	$–	$–

11. Other.

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

Funds do not invest in underlying mutual funds for the purpose of exercising management or control; however, investments by funds within their principal investment strategies may represent a significant portion of the underlying mutual fund's net assets. At the end of the period, certain Funds were the owners of record of 10% or more of the total outstanding shares of the following underlying mutual funds as shown below.

Fund	Fidelity Disruptors Fund
Fidelity Disruptive Automation Fund	21%
Fidelity Disruptive Communications Fund	52%
Fidelity Disruptive Finance Fund	39%
Fidelity Disruptive Medicine Fund	46%

12. Coronavirus (COVID-19) Pandemic.

An outbreak of COVID-19 first detected in China during December 2019 has since spread globally and was declared a pandemic by the World Health Organization during March 2020. Developments that disrupt global economies and financial markets, such as the COVID-19 pandemic, may magnify factors that affect the Funds' performance.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Summer Street Trust and Shareholders of Fidelity Disruptive Automation Fund, Fidelity Disruptive Communications Fund, Fidelity Disruptive Finance Fund, Fidelity Disruptive Medicine Fund and Fidelity Disruptive Technology Fund

Opinions on the Financial Statements

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of Fidelity Disruptive Automation Fund, Fidelity Disruptive Communications Fund, Fidelity Disruptive Finance Fund, Fidelity Disruptive Medicine Fund and Fidelity Disruptive Technology Fund (five of the funds constituting Fidelity Summer Street Trust, hereafter collectively referred to as the “Funds”) as of May 31, 2022, the related statements of operations for the year ended May 31, 2022, the statements of changes in net assets for each of the two years in the period ended May 31, 2022, including the related notes, and the financial highlights for each of the two years in the period ended May 31, 2022 and for the period April 16, 2020 (commencement of operations) through May 31, 2020 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of May 31, 2022, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended May 31, 2022 and each of the financial highlights for each of the two years in the period ended May 31, 2022 and for the period April 16, 2020 (commencement of operations) through May 31, 2020 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinions

These financial statements are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ financial statements 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 of these financial statements 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 are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, 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. 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. Our procedures included confirmation of securities owned as of May 31, 2022 by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinions.

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. Each of the Trustees oversees 325 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 if you’re an individual investing directly with Fidelity, call 1-800-835-5092 if you’re a plan sponsor or participant with Fidelity as your recordkeeper or call 1-877-208-0098 on institutional accounts or if you’re an advisor or invest through one.

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. Robert A. Lawrence is an interested person and currently serves as Chair. The Trustees have determined that an interested Chair is appropriate and benefits shareholders because an interested Chair 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 Chair, 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 Chair 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. David M. Thomas serves as Lead Independent Trustee 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 high income and certain equity funds, and other Boards oversee Fidelity's investment-grade bond, money market, asset allocation, and other equity funds. The asset allocation funds may invest in Fidelity^® funds overseen by the funds' Board. 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, Audit, and Compliance Committees. 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, you incur two types of costs: (1) transaction costs, which may include sales charges (loads) on purchase payments or redemption proceeds, as applicable and (2) ongoing costs, which generally include management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in a fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (December 1, 2021 to May 31, 2022).

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Disruptive Automation Fund

Fidelity Disruptive Communications Fund

Fidelity Disruptive Finance Fund

Fidelity Disruptive Medicine Fund

Fidelity Disruptive Technology Fund

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract with Fidelity Management & Research Company LLC (FMR) and the sub-advisory agreements (together, the Advisory Contracts) for each fund. FMR and the sub-advisers are referred to herein as the Investment Advisers. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and, at each of its meetings, covers an extensive agenda of topics and materials and considers factors that are relevant to its annual consideration of the renewal of each fund's Advisory Contracts, including the services and support provided to each fund and its shareholders. The Board has established various standing committees (Committees), each composed of and chaired by Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of each fund's Advisory Contracts. The Board also meets as needed to review matters specifically related to the Board's annual consideration of the renewal of the Advisory Contracts. Members of the Board may also meet with trustees of other Fidelity funds through joint ad hoc committees to discuss certain matters relevant to all of the Fidelity funds.

At its May 2022 meeting, the Board unanimously determined to renew each fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services provided to each fund and its shareholders (including the investment performance of each fund); (ii) the competitiveness relative to peer funds of each fund's management fee and the total expense ratio of a representative class (retail class) of each fund; (iii) the total costs of the services provided by and the profits realized by Fidelity from its relationships with each fund; and (iv) the extent to which, if any, economies of scale exist and are realized as each fund grows, and whether any economies of scale are appropriately shared with fund shareholders.

In considering whether to renew the Advisory Contracts for each fund, the Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts was in the best interests of each fund and its shareholders and that the compensation payable under the Advisory Contracts was fair and reasonable. The Board's decision to renew the Advisory Contracts was not based on any single factor, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, was aware that shareholders of each fund have a broad range of investment choices available to them, including a wide choice among funds offered by Fidelity's competitors, and that each fund's shareholders, who have the opportunity to review and weigh the disclosure provided by the fund in its prospectus and other public disclosures, have chosen to invest in that fund, which is part of the Fidelity family of funds.

Nature, Extent, and Quality of Services Provided. The Board considered Fidelity's staffing as it relates to the funds, including the backgrounds of investment personnel of Fidelity, and also considered the funds' investment objectives, strategies, and related investment philosophies. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the investment personnel compensation program and whether this structure provides appropriate incentives to act in the best interests of each fund. Additionally, the Board considered the portfolio managers' investments, if any, in the funds that they manage. The Board also considered the steps Fidelity had taken to ensure the continued provision of high quality services to the Fidelity funds during the COVID-19 pandemic, including the expansion of staff in client facing positions to maintain service levels in periods of high volumes and volatility.

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

Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for each fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians, subcustodians, and pricing vendors; and (iii) the resources devoted to, and the record of compliance with, each fund's compliance policies and procedures. The Board also reviewed the allocation of fund brokerage, including allocations to brokers affiliated with the Investment Advisers, the use of brokerage commissions to pay fund expenses, and the use of "soft" commission dollars to pay for research services.

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

Investment in a Large Fund Family. The Board considered the benefits to shareholders of investing in a Fidelity fund, including the benefits of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing a large variety of mutual fund investor services. The Board noted that Fidelity had taken, or had made recommendations that resulted in the Fidelity funds taking, a number of actions over the previous year that benefited particular funds, including: (i) continuing to dedicate additional resources to Fidelity's investment research process, which includes meetings with management of issuers of securities in which the funds invest; (ii) continuing efforts to enhance Fidelity's global research capabilities; (iii) launching new funds and ETFs with innovative structures, strategies and pricing and making other enhancements to meet client needs; (iv) launching new share classes of existing funds; (v) eliminating purchase minimums and broadening eligibility requirements for certain funds and share classes; (vi) reducing management fees and total expenses for certain target date funds and classes and index funds; (vii) lowering expenses for certain existing funds and classes by implementing or lowering expense caps; (viii) rationalizing product lines and gaining increased efficiencies from fund mergers and liquidations; (ix) continuing to develop, acquire and implement systems and technology to improve services to the funds and shareholders, strengthen information security, and increase efficiency; and (x) continuing to implement enhancements to further strengthen Fidelity's product line to increase investors' probability of success in achieving their investment goals, including retirement income goals.

Investment Performance. The Board considered whether each fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions and its performance history. The Board noted that the Fidelity Disruptive Automation Fund, the Fidelity Disruptive Communications Fund, the Fidelity Disruptive Finance Fund, the Fidelity Disruptive Medicine Fund and the Fidelity Disruptive Technology Fund each had portfolio manager changes in July 2020 and November 2020. The Board will continue to closely monitor each fund's performance, taking into account the portfolio manager changes.

The Board took into account discussions that occur at Board meetings throughout the year with representatives of the Investment Advisers about fund investment performance. In this regard the Board noted that as part of regularly scheduled fund reviews and other reports to the Board on fund performance, the Board considers annualized return information for each fund for different time periods, measured against an appropriate securities market index (benchmark index). The Board also reviews and considers information about performance attribution. In its evaluation of fund investment performance, the Board gave particular attention to information indicating changes in performance of certain Fidelity funds for specific time periods and discussed with the Investment Advisers the reasons for any overperformance or underperformance.

In addition to reviewing absolute and relative fund performance, the Independent Trustees periodically consider the appropriateness of fund performance metrics in evaluating the results achieved. In general, the Independent Trustees believe that fund performance should be evaluated based on net performance (after fees and expenses) of the representative class, compared to appropriate benchmark indices, over appropriate time periods that may include full market cycles, taking into account relevant factors including the following: general market conditions; issuer-specific information; and fund cash flows and other factors.

The Independent Trustees recognize that shareholders evaluate performance on a net basis over their own holding periods, for which one-, three-, and five-year periods are often used as a proxy. For this reason, the performance information reviewed by the Board also included net total return information for each fund and an appropriate benchmark index for the most recent one-year period ended September 30, 2021, as shown below. Peer groups are not shown below because the funds do not generally utilize a peer group for performance comparison purposes.

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

Competitiveness of Management Fee and Total Expense Ratio. The Board considered each fund's management fee and total expense ratio compared to "mapped groups" of competitive funds and classes created for the purpose of facilitating the Trustees' competitive analysis of management fees and total expenses. Fidelity creates "mapped groups" by combining similar Lipper investment objective categories that have comparable investment mandates. For this purpose, all sector focused equity funds are grouped in the same mapped group. Combining Lipper investment objective categories aids the Board's management fee and total expense ratio comparisons by broadening the competitive group used for comparison.

Management Fee. The Board considered two proprietary management fee comparisons for the 12-month (or shorter) periods ended September 30 shown in basis points (BP) in the charts below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing in terms of gross management fees before expense reimbursements or caps relative to the total universe of funds with comparable investment mandates (i.e., sector equities), regardless of whether their management fee structures also are comparable. Funds with comparable management fee structures have similar management fee contractual arrangements (e.g., flat rate charged for advisory services, all-inclusive fee rate, etc.). "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than a fund's. For example, a hypothetical TMG % of 20% would mean that 80% of the funds in the Total Mapped Group had higher, and 20% had lower, management fees than a fund. The funds' actual TMG %s and the number of funds in the Total Mapped Group are in the charts below. The "Asset-Sized Peer Group" (ASPG) comparison focuses on a fund's standing relative to a subset of non-Fidelity funds within the Total Mapped Group that are similar in size and management fee structure. For example, if a fund is in the first quartile of the ASPG, the fund's management fee ranks in the least expensive or lowest 25% of funds in the ASPG. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee structures, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which a fund's management fee rate ranked, is also included in the charts and was considered by the Board.

The Board noted that each fund's management fee rate ranked above the median of its Total Mapped Group and above the median of its ASPG for the period ended September 30, 2021. The Board considered that each fund has a unitary fee that covers expenses beyond portfolio management, whereas the majority of funds within each fund's Total Mapped Group and ASPG do not have management fees that cover services and fees beyond portfolio management.

The Board also considered that, for funds subject to the group fee, FMR agreed to voluntarily waive fees over a specified period of time in amounts designed to account for assets converted from certain funds to certain collective investment trusts.

Based on its review, the Board concluded that each fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.

Total Expense Ratio. In its review of the total expense ratio of the representative class (the retail class) of each fund, the Board considered the fund's unitary fee rate as well as other fund or class expenses, as applicable, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. The Board also noted that Fidelity may agree to waive fees or reimburse expenses from time to time, and the extent to which, if any, it has done so for the fund. Each fund's representative class is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure. The Board also considered a total expense ASPG comparison for the representative class, which focuses on the total expenses of the representative class relative to a subset of non-Fidelity funds within the total expense similar sales load structure group. The total expense ASPG is limited to 15 larger and 15 smaller classes in fund average assets for a total of 30 classes, where possible. The total expense ASPG comparison excludes performance adjustments and fund-paid 12b-1 fees to eliminate variability in fee structures.

The Board noted that the total net expense ratio of the retail class of each fund ranked above the similar sales load structure group competitive median and below the ASPG competitive median for the period ended September 30, 2021. The Board considered that, in general, various factors can affect total expense ratios. The Board noted the funds' unique loyalty pricing structure.

The Board considered that current contractual arrangements for each fund oblige FMR to pay all "class-level" expenses of each class of each fund to the extent necessary to limit total operating expenses, with certain exceptions, as follows: Loyalty Class 1: 0.75%; Loyalty Class 2: 0.50%; and Class F: 0.00%. These contractual arrangements may not be amended to increase the fees or expenses payable except by a vote of a majority of the Board. The Board also considered these contractual arrangements reflect each fund's unique loyalty pricing structure where shareholders that hold fund shares over longer periods of time are eligible to have their retail class shares converted to Loyalty Class 1 and Loyalty Class 2, depending on their holding period.

Fees Charged to Other Fidelity Clients. The Board also considered Fidelity fee structures and other information with respect to clients of Fidelity, such as other funds advised or subadvised by Fidelity, pension plan clients, and other institutional clients with similar mandates. The Board noted that a joint ad hoc committee created by it and the boards of other Fidelity funds periodically reviews and compares Fidelity's institutional investment advisory business with its business of providing services to the Fidelity funds and also noted the most recent findings of the committee. The Board noted that the committee's review included a consideration of the differences in services provided, fees charged, and costs incurred, as well as competition in the markets serving the different categories of clients.

Based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that the total expense ratio of each class of each fund was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability. The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering, and servicing each fund and servicing each fund's shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

On an annual basis, Fidelity presents to the Board information about the profitability of its relationships with each fund. Fidelity calculates profitability information for each fund, as well as aggregate profitability information for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the books and records of Fidelity on which Fidelity's audited financial statements are based. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies and the full Board approves such changes.

A public accounting firm has been engaged annually by the Board as part of the Board's assessment of Fidelity's profitability analysis. The engagement includes the review and assessment of the methodologies used by Fidelity in determining the revenues and expenses attributable to Fidelity's mutual fund business, and completion of agreed-upon procedures in respect of the mathematical accuracy of certain fund profitability information and its conformity to established allocation methodologies. After considering the reports issued under the engagement and information provided by Fidelity, the Board concluded that while other allocation methods may also be reasonable, Fidelity's profitability methodologies are reasonable in all material respects.

The Board also reviewed Fidelity's non-fund businesses and potential indirect benefits such businesses may have received as a result of their association with Fidelity's mutual fund business (i.e., fall-out benefits) as well as cases where Fidelity's affiliates may benefit from the funds' business. The Board considered areas where potential indirect benefits to the Fidelity funds from their relationships with Fidelity may exist. The Board's consideration of these matters was informed by the findings of a joint ad hoc committee created by it and the boards of other Fidelity funds to evaluate potential fall-out benefits.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of each fund and was satisfied that the profitability was not excessive.

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including each fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which each fund will benefit from economies of scale as assets grow through increased services to the fund, through waivers or reimbursements, or through fee or expense ratio reductions. The Board recognized that, due to the fund's current contractual arrangements, its expense ratio will not decline if the fund's operating costs decrease as assets grow, or rise as assets decrease. The Board also noted that a committee (the Economies of Scale Committee) created by it and the boards of other Fidelity funds periodically analyzes whether Fidelity attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' advisory contracts, the Board requested and received additional information on certain topics, including: (i) fund flow and performance trends, in particular the underperformance of certain funds and strategies, and Fidelity's long-term strategies for certain funds, including any consideration of fund liquidations or mergers; (ii) the operation of performance fees, competitor use of performance fees, and consideration of the expansion of performance fees to additional funds; (iii) Fidelity's pricing philosophy compared to competitors; (iv) fund profitability methodology and data; (v) evaluation of competitive fund data and peer group classifications and fee and expense comparisons; (vi) the management fee and expense structures for different funds and classes and information about the differences between various fee and expense structures; (vii) group fee breakpoints and related voluntary fee waivers; and (viii) information regarding other accounts managed by Fidelity and the funds' sub-advisory arrangements.

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

Liquidity Risk Management Program

The Securities and Exchange Commission adopted Rule 22e-4 under the Investment Company Act of 1940 (the Liquidity Rule) to promote effective liquidity risk management throughout the open-end investment company industry, thereby reducing the risk that funds will be unable to meet their redemption obligations and mitigating dilution of the interests of fund shareholders.

The Funds have adopted and implemented a liquidity risk management program pursuant to the Liquidity Rule (the Program) effective December 1, 2018. The Program is reasonably designed to assess and manage each Fund’s liquidity risk and to comply with the requirements of the Liquidity Rule. Each Fund’s Board of Trustees (the Board) has designated each Fund’s investment adviser as administrator of the Program. The Fidelity advisers have established a Liquidity Risk Management Committee (the LRM Committee) to manage the Program for each of the Fidelity Funds. The LRM Committee monitors the adequacy and effectiveness of implementation of the Program and on a periodic basis assesses each Fund’s liquidity risk based on a variety of factors including (1) the Fund’s investment strategy, (2) portfolio liquidity and cash flow projections during normal and reasonably foreseeable stressed conditions, (3) shareholder redemptions, (4) borrowings and other funding sources and (5) in the case of exchange-traded funds, certain additional factors including the effect of the Fund’s prices and spreads, market participants, and basket compositions on the overall liquidity of the Fund’s portfolio, as applicable.

In accordance with the Program, each of the Fund’s portfolio investments is classified into one of four liquidity categories described below based on a determination of a reasonable expectation for how long it would take to convert the investment to cash (or sell or dispose of the investment) without significantly changing its market value.

Highly liquid investments – cash or convertible to cash within three business days or less
Moderately liquid investments – convertible to cash in three to seven calendar days
Less liquid investments – can be sold or disposed of, but not settled, within seven calendar days
Illiquid investments – cannot be sold or disposed of within seven calendar days

Liquidity classification determinations take into account a variety of factors including various market, trading and investment-specific considerations, as well as market depth, and generally utilize analysis from a third-party liquidity metrics service.

The Liquidity Rule places a 15% limit on a fund’s illiquid investments and requires funds that do not primarily hold assets that are highly liquid investments to determine and maintain a minimum percentage of the fund’s net assets to be invested in highly liquid investments (highly liquid investment minimum or HLIM). The Program includes provisions reasonably designed to comply with the 15% limit on illiquid investments and for determining, periodically reviewing and complying with the HLIM requirement as applicable.

At a recent meeting of the Fund’s Board of Trustees, the LRM Committee provided a written report to the Board pertaining to the operation, adequacy, and effectiveness of implementation of the Program for the annual period from December 1, 2020 through November 30, 2021. The report concluded that the Program has been implemented and is operating effectively and is reasonably designed to assess and manage the Fund’s liquidity risk.

Management's Discussion of Fund Performance

Comments from Co-Portfolio Managers Steven Calhoun and David Wagner: For the fiscal year ending May 31, 2022, the fund gained 15.24%, outperforming the 13.03% advance of the MSCI ACWI Select Agriculture Producers IMI 25/50 Index (Net MA), as well as the broad-based MSCI All Country World Index (Net MA). By country, underweighting Japan, stock picks in the U.S. and an overweighting in Canada contributed most to the fund's relative result the past 12 months. Versus the industry index, security selection in fertilizers & agricultural chemicals boosted the fund's relative result most. Also boosting performance was stock selection in agricultural products. The fund's top individual relative contributor was an overweighting in CF Industries Holdings, which gained 89% the past twelve months. The company was among our largest holdings. Also lifting performance was our outsized stake in Mosaic, which gained 72%. Mosaic was among the fund's biggest holdings. Another notable relative contributor was an overweighting in Nutrien (+60%). We increased our stakes in CF Industries, Mosaic and Nutrien during the period. Foreign holdings contributed overall despite continued U.S. dollar strength. In contrast, an overweighting and stock picks in the U.K. notably detracted from the fund's relative result. A lack of exposure to Israel and stock choices in Norway also hurt relative performance. From an industry perspective, security selection in packaged foods & meats was the largest detractor versus the benchmark. In terms of individual stocks, a non-benchmark stake in Nomad Foods was the fund's largest individual relative detractor, due to its approximate -26% result. Positions in Nomad Foods were sold the past year. Another notable relative detractor was an outsized stake in Toro (-25%). This period we increased the fund's stake in Toro. Also holding back performance was an underweighting and untimely positioning in SABIC Agri-Nutrients, which gained 47%. We established a position in the company the past twelve months.

Management's Discussion of Fund Performance

Comments from Portfolio Manager Janet Glazer: For the fiscal year ending May 31, 2022, the fund returned -7.44%, outperforming the -8.24% return of the S&P Global Water Index, but underperforming the broad-based MSCI All Country World Index (Net MA). By region, a large overweighting and stock picks in the U.S., as well as an underweighting in Europe ex U.K., specifically Switzerland, contributed most to the fund's relative result. Looking at industry weightings, out-of-benchmark exposure to electrical components & equipment lifted relative performance most, followed by favorable picks and an overweighting in industrial machinery and a non-benchmark stake in application software. Our top individual relative contributor was an out-of-benchmark position in Regal Rexnord (-1%). The company was not held at period end. Also helping performance was our lighter-than-benchmark stake in Xylem, which returned -28%. The fund's non-benchmark stake in Roper Technologies – another relative contributor – returned roughly -1%. We added to our stake in the company the past twelve months, and it was the fund’s largest holding as of May 31. Conversely, an underweighting and stock picks in the U.K. and an out-of-benchmark allocation to Sweden hurt the fund's relative result. By industry, the primary detractors from performance versus the benchmark were stock selection in building products and an underweighting in water utilities. The biggest individual relative detractor was a sizable overweighting in Zurn Water Solutions (-43%). Although Zurn was among the fund's largest holdings at the beginning of the period, we considerably reduced the position. Other notable relative detractors included an underweighting in Olin (+37%) and a lighter-than-benchmark stake in Severn Trent (+7%). The latter was among the fund’s biggest holdings as of May 31.

Notes to Financial Statements

For the period ended May 31, 2022

1. Organization.

Fidelity Agricultural Productivity Fund and Fidelity Water Sustainability Fund (the Funds) are non-diversified funds of Fidelity Summer Street Trust (the Trust). Each Fund 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. Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Funds' exposure to certain issuers, sectors, regions, and countries and may affect the Funds' performance depending on whether certain investments are in or out of favor. The criteria related to the Funds' ESG ratings process and/or adherence to its sustainable investing exclusion criteria may result in the Funds forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so, or selling securities for ESG reasons when it might be otherwise disadvantageous for it to do so. As a result, the Funds' performance may at times be better or worse than the performance of funds that do not use ESG or sustainability criteria. There are significant differences in interpretations of what it means for an issuer to have positive ESG factors. While the investment adviser believes its definitions are reasonable, the portfolio decisions it makes may differ with other investors' or advisers' views.

2. Investments in Fidelity Central Funds.

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

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

3. Significant Accounting Policies.

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

Level 1 – unadjusted quoted prices in active markets for identical investments
Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

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

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, 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.

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 May 31, 2022 is included at the end of each Fund's Schedule of Investments.

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. Commissions paid to certain brokers with whom the investment adviser, or its affiliates, places trades on behalf of a fund include an amount in addition to trade execution, which may be rebated back to a fund. Any such rebates are included in net realized gain (loss) on investments in the Statement of Operations. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Funds are informed of the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Large, non-recurring dividends recognized by the Funds are presented separately on the Statement of Operations as "Special Dividends" and the impact of these dividends is presented in the Financial Highlights. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain. Funds may file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld. Any withholding tax reclaims income is included in the Statement of Operations in dividends. Any receivables for withholding tax reclaims are included in the Statement of Assets and Liabilities in dividends receivable.

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

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 Funds claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

Book-tax differences are primarily due to foreign currency transactions, net operating losses, capital loss carryforwards and losses deferred due to wash sales and excise tax regulations.

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

	Tax cost	Gross unrealized appreciation	Gross unrealized depreciation	Net unrealized appreciation (depreciation)
Fidelity Agricultural Productivity Fund	$152,646,245	$21,908,057	$(7,737,752)	$14,170,305
Fidelity Water Sustainability Fund	100,917,027	5,273,560	(8,107,360)	(2,833,800)

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

	Undistributed ordinary income	Capital loss carryforward	Net unrealized appreciation (depreciation) on securities and other investments
Fidelity Agricultural Productivity Fund	$383,302	$(2,800,265)	14,170,108
Fidelity Water Sustainability Fund	–	–	(2,834,066)

	Short-term
Fidelity Agricultural Productivity Fund	$(2,800,265)

	Capital losses	Ordinary losses

4. Purchases and Sales of Investments.

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

	Purchases ($)	Sales ($)

Fidelity Water Sustainability Fund	102,602,242	52,402,453

5. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Funds with investment management related services for which the Funds pay a monthly management fee. The management fee is the sum of an individual fund fee rate and an annualized group fee rate. The individual fund fee rate is applied to each Fund's average net assets. The group fee rate is based upon the monthly average net assets of a group of registered investment companies with which the investment adviser has management contracts.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Summer Street Trust and Shareholders of Fidelity Agricultural Productivity Fund and Fidelity Water Sustainability Fund

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statements of assets and liabilities of Fidelity Agricultural Productivity Fund and Fidelity Water Sustainability Fund (the "Funds"), each a fund of Fidelity Summer Street Trust, including the schedules of investments, as of May 31, 2022, 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 two years in the period then ended and for the period from April 16, 2020 (commencement of operations) through May 31, 2020, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Funds as of May 31, 2022, 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 two years in the period then ended and for the period from April 16,2020 (commencement of operations) through May 31, 2020, 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 May 31, 2022, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Agricultural Productivity Fund
Fidelity Water Sustainability Fund

At its May 2022 meeting, the Board unanimously determined to renew each fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services provided to each fund and its shareholders (including the investment performance of each fund); (ii) the competitiveness relative to peer funds of each fund's management fee and total expense ratio; (iii) the total costs of the services provided by and the profits realized by Fidelity from its relationships with each fund; and (iv) the extent to which, if any, economies of scale exist and are realized as each fund grows, and whether any economies of scale are appropriately shared with fund shareholders.

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

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

In addition to reviewing absolute and relative fund performance, the Independent Trustees periodically consider the appropriateness of fund performance metrics in evaluating the results achieved. In general, the Independent Trustees believe that fund performance should be evaluated based on net performance (after fees and expenses) of the fund compared to appropriate benchmark indices, over appropriate time periods that may include full market cycles, taking into account relevant factors including the following: general market conditions; issuer-specific information; and fund cash flows and other factors.

The Independent Trustees recognize that shareholders evaluate performance on a net basis over their own holding periods, for which one-, three-, and five-year periods are often used as a proxy. For this reason, the performance information reviewed by the Board also included net total return information for each fund and an appropriate benchmark index for the most recent one year period ended September 30, 2021, as shown below.

Fidelity Agricultural Productivity Fund

Fidelity Water Sustainability Fund

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

Management Fee. The Board considered two proprietary management fee comparisons for the 12-month (or shorter) periods ended September 30 shown in basis points (BP) in the charts below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing in terms of gross management fees before expense reimbursements or caps, relative to the total universe of funds with comparable investment mandates (i.e., sector equities), regardless of whether their management fee structures also are comparable. Funds with comparable management fee structures have similar management fee contractual arrangements (e.g., flat rate charged for advisory services, all-inclusive fee rate, etc.). "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than a fund's. For example, a hypothetical TMG % of 20% would mean that 80% of the funds in the Total Mapped Group had higher, and 20% had lower, management fees than a fund. The funds' actual TMG % and the number of funds in the Total Mapped Group are in the charts below. The "Asset-Sized Peer Group" (ASPG) comparison focuses on a fund's standing relative to a subset of non-Fidelity funds within the Total Mapped Group that are similar in size and management fee structure. For example, if a fund is in the first quartile of the ASPG, the fund's management fee ranks in the least expensive or lowest 25% of funds in the ASPG. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee structures, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which a fund's management fee rate ranked, is also included in the charts and was considered by the Board.

Fidelity Agricultural Productivity Fund

Fidelity Water Sustainability Fund

The Board noted that each fund's management fee rate ranked below the median of its Total Mapped Group and below the median of its ASPG for the 12-month period ended September 30, 2021.

Based on its review, the Board concluded that each fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.

Total Expense Ratio. In its review of each fund's total expense ratio, the Board considered the fund's management fee rate as well as other fund expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. The Board also noted that Fidelity may agree to waive fees or reimburse expenses from time to time, and the extent to which, if any, it has done so for each fund. Each fund is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure. The Board also considered a total expense ASPG comparison for each fund, which focuses on the total expenses of the fund relative to a subset of non-Fidelity funds within the total expense similar sales load structure group. The total expense ASPG is limited to 15 larger and 15 smaller classes in fund average assets for a total of 30 classes, where possible. The total expense ASPG comparison excludes performance adjustments and fund-paid 12b-1 fees to eliminate variability in fee structures.

The Board noted that each fund's total net expense ratio ranked above the similar sales load structure group competitive median and below the ASPG competitive median for the period ended September 30, 2021. The Board considered that, in general, various factors can affect total expense ratios. With respect to Fidelity Agricultural Productivity Fund, the fund's total expense ratio was above the similar sales load structure group competitive median primarily as a result of higher fixed other expenses due to lower asset levels. With respect to Fidelity Water Sustainability Fund, when compared to other thematic funds in its similar sales load structure group, the fund's total expense ratio was below the median.

The Board considered that FMR has contractually agreed to reimburse each fund to the extent that total operating expenses, with certain expenses, as a percentage of their respective average net assets, exceed 1.00% through September 30, 2022.

Based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that the total expense ratio of each fund was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability. The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing each fund and servicing each fund's shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including each fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which each fund will benefit from economies of scale as assets grow through increased services to the fund, through waivers or reimbursements, or through fee or expense ratio reductions. The Board also noted that a committee (the Economies of Scale Committee) created by it and the boards of other Fidelity funds periodically analyzes whether Fidelity attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board recognized that each fund's management contract incorporates a "group fee" structure, which provides for lower group fee rates as total "group assets" increase, and for higher group fee rates as total "group assets" decrease ("group assets" as defined in the management contracts). FMR calculates the group fee rates based on a tiered asset "breakpoint" schedule that varies based on asset class. The Board considered that the group fee is designed to deliver the benefits of economies of scale to fund shareholders when total Fidelity fund assets increase, even if assets of any particular fund are unchanged or have declined, because some portion of Fidelity's costs are attributable to services provided to all Fidelity funds, and all funds benefit if those costs can be allocated among more assets. The Board further considered that Fidelity agreed to impose a temporary fee waiver in the form of additional breakpoints to the current breakpoint schedule. The Board concluded that, given the group fee structure, fund shareholders will benefit from lower management fees as "group assets" increase at the fund complex level, regardless of whether Fidelity achieves any such economies of scale.

The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.

Management's Discussion of Fund Performance

Comments from Co-Managers Charlie Hebard and Christopher Lee: For the fiscal year ending May 31, 2022, the fund's share classes returned roughly -23%, underperforming the -6.49% return of the broad-based MSCI All Country World Index (Net MA). By region, stock picks in the U.S., Singapore and Japan hurt the fund's relative result. By industry, the primary detractor from performance versus the benchmark was stock selection in biotechnology. An overweighting in application software and positioning in interactive media & services also notably hampered the fund's relative result. Our overweight stake in Sea, the fund's top individual detractor relative to the benchmark, returned approximately -68% this period. Our second-largest detractor was Snap, which returned roughly -77% the past year. We boosted exposure to both Sea and Snap during the reporting period. An underweighting in index component Apple was another top detractor this period. The stock returned 20% the past twelve months. Conversely, an underweighting in emerging markets, specifically South Korea, China and Hong Kong, and security selection in Belgium contributed to the fund's relative result. By industry, the primary contributor to performance versus the benchmark was stock selection in internet services & infrastructure. An overweight position in managed health care also helped the fund's relative result, as did strong picks in communications equipment and wireless telecommunication services. The biggest individual relative contributor was our positioning in Cloudflare. Also bolstering performance were overweight stakes in Arch Capital Group (+19%) and Nvidia (+15%). Nvidia was among the fund's largest holdings the past twelve months. The fund's higher-than-index stake in Regeneron Pharmaceuticals, returned about 32% and notably contributed. We pared our positions in Cloudflare, Arch, Nvidia and Regeneron during the period.

Notes to Financial Statements

For the period ended May 31, 2022

1. Organization.

Fidelity Disruptors Fund (the Fund) is a fund of Fidelity Summer Street Trust (the Trust). 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 authorized to issue an unlimited number of shares. The Fund offers Fidelity Disruptors Fund, Loyalty Class 1 and Loyalty Class 2 shares. Each class has equal rights as to assets and voting privileges, except for matters affecting a single class. For certain accounts, Fidelity Disruptors Fund shares will automatically convert to Loyalty Class 1 shares after a holding period of one year from the initial date of purchase; and then from Loyalty Class 1 shares to Loyalty Class 2 shares after another holding period of two years.

2. 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 - Investment Companies. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The Fund's Schedule of Investments lists any underlying mutual funds or exchange-traded funds (ETFs) but does not include the underlying holdings of these funds. The following summarizes the significant accounting policies of the Fund:

Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. 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 – unadjusted quoted prices in active markets for identical investments
Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows. Investments in open-end mutual funds are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy. The aggregate value of investments by input level as of May 31, 2022 is included at the end of the Fund's Schedule of Investments.

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 May 31, 2022, 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.

Book-tax differences are primarily due to the short-term gain distributions from the underlying mutual funds or exchange-traded funds (ETFs), 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	$6,979,029
Gross unrealized depreciation	(18,983,909)
Net unrealized appreciation (depreciation)	$(12,004,880)
Tax Cost	$137,718,907

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

Net unrealized appreciation (depreciation) on securities and other investments

$(12,004,880)

The Fund intends to elect to defer to its next fiscal year $2,717,555 of capital losses recognized during the period November 1, 2021 to May 31, 2022.

The tax character of distributions paid was as follows:

	May 31, 2022	May 31, 2021
Ordinary Income	$2,610,566	$ 722,470
Long-term Capital Gains	129,714	–
Total	$2,740,280	$ 722,470

3. Purchases and Sales of Investments.

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

	Purchases ($)	Sales ($)
Fidelity Disruptors Fund	43,005,554	38,501,671

4. Fees and Other Transactions with Affiliates.

Management Fee and Expense Contract. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Fund with investment management related services for which each Class of the Fund pays a monthly all-inclusive management fee based on an annual percentage of class-level average net assets. Under the management contract, the investment adviser pays all other operating expenses, except the compensation of the independent Trustees and certain miscellaneous expenses, such as proxy and shareholder meeting expenses.

Under the expense contract, the investment adviser pays all other class-level operating expenses as necessary, except the compensation of the independent Trustees and certain miscellaneous expenses, such as proxy and shareholder meeting expenses, so that total expenses of Loyalty Class 1 and Loyalty Class 2 do not exceed an annual percentage of class-level average net assets.

For the reporting period, the annual management fee and expense contract rates were as follows:

	Management Fee Annual % of Class-Level Average Net Assets	Expense Contract Annual % of Class-Level Average Net Assets
Fidelity Disruptors Fund	1.00%	N/A
Loyalty Class 1	1.00%	.75%
Loyalty Class 2	1.00%	.50%

5. Committed Line of Credit.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Summer Street Trust and Shareholders of Fidelity Disruptors Fund

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Fidelity Disruptors Fund (the "Fund"), a fund of Fidelity Summer Street Trust, including the schedule of investments, as of May 31, 2022, 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 April 16, 2020 (commencement of operations) through May 31, 2020, 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 May 31, 2022, 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 April 16, 2020 (commencement of operations) through May 31, 2020, 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.

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. If the interests of the fund and an underlying Fidelity^® fund were to diverge, a conflict of interest could arise and affect how the Trustees and Members of the Advisory Board fulfill their fiduciary duties to the affected funds. FMR has structured the fund to avoid these potential conflicts, although there may be situations where a conflict of interest is unavoidable. In such instances, FMR, the Trustees, and Members of the Advisory Board would take reasonable steps to minimize and, if possible, eliminate the conflict. Each of Trustees oversees 325 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. Robert A. Lawrence is an interested person and currently serves as Chair. The Trustees have determined that an interested Chair is appropriate and benefits shareholders because an interested Chair 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 Chair, 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 Chair 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. David M. Thomas serves as Lead Independent Trustee 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 high income and certain equity funds, and other Boards oversee Fidelity's investment-grade bond, money market, asset allocation, and other equity funds. The asset allocation funds may invest in Fidelity^® funds overseen by the fund's Board. 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, Audit, and Compliance Committees. 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."

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Disruptors Fund

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract with Fidelity Management & Research Company LLC (FMR) and the sub-advisory agreements (together, the Advisory Contracts) for the fund. FMR and the sub-advisers are referred to herein as the Investment Advisers. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and, at each of its meetings, covers an extensive agenda of topics and materials and considers factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board has established various standing committees (Committees), each composed of and chaired by Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of the fund's Advisory Contracts. The Board also meets as needed to review matters specifically related to the Board's annual consideration of the renewal of the Advisory Contracts. Members of the Board may also meet with trustees of other Fidelity funds through joint ad hoc committees to discuss certain matters relevant to all of the Fidelity funds.

At its May 2022 meeting, the Board unanimously determined to renew the fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness relative to peer funds of the fund's management fee and the total expense ratio of a representative class (retail class); (iii) the total costs of the services provided by and the profits realized by Fidelity from its relationships with the fund; and (iv) the extent to which, if any, economies of scale exist and are realized as the fund grows, and whether any economies of scale are appropriately shared with fund shareholders.

In considering whether to renew the Advisory Contracts for the fund, the Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts was in the best interests of the fund and its shareholders and that the compensation payable under the Advisory Contracts was fair and reasonable. The Board's decision to renew the Advisory Contracts was not based on any single factor, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, was aware that shareholders of the fund have a broad range of investment choices available to them, including a wide choice among funds offered by Fidelity's competitors, and that the fund's shareholders, who have the opportunity to review and weigh the disclosure provided by the fund in its prospectus and other public disclosures, have chosen to invest in this fund, which is part of the Fidelity family of funds.

Nature, Extent, and Quality of Services Provided. The Board considered Fidelity's staffing as it relates to the fund, including the backgrounds of investment personnel of Fidelity, and also considered the fund's investment objective, strategies, and related investment philosophy. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the investment personnel compensation program and whether this structure provides appropriate incentives to act in the best interests of the fund. Additionally, the Board considered the portfolio managers' investments, if any, in the funds that they manage. The Board also considered the steps Fidelity had taken to ensure the continued provision of high quality services to the Fidelity funds during the COVID-19 pandemic, including the expansion of staff in client facing positions to maintain service levels in periods of high volumes and volatility.

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

Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians, subcustodians, and pricing vendors; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures. The Board also reviewed the allocation of fund brokerage, including allocations to brokers affiliated with the Investment Advisers, the use of brokerage commissions to pay fund expenses, and the use of "soft" commission dollars to pay for research services.

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

Investment Performance. The Board considered whether the fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions and its performance history. The Board noted that the fund had portfolio manager changes in July 2020 and November 2020. The Board will continue to monitor closely the fund's performance, taking into account the portfolio manager changes.

The Board took into account discussions that occur at Board meetings throughout the year with representatives of the Investment Advisers about fund investment performance. In this regard the Board noted that as part of regularly scheduled fund reviews and other reports to the Board on fund performance, the Board considers annualized return information for the fund for different time periods, measured against an appropriate securities market index (benchmark index). The Board also reviews and considers information about performance attribution. In its evaluation of fund investment performance, the Board gave particular attention to information indicating changes in performance of certain Fidelity funds for specific time periods and discussed with the Investment Advisers the reasons for any overperformance or underperformance.

In addition to reviewing absolute and relative fund performance, the Independent Trustees periodically consider the appropriateness of fund performance metrics in evaluating the results achieved. In general, the Independent Trustees believe that fund performance should be evaluated based on net performance (after fees and expenses) of the representative class, compared to appropriate benchmark indices, over appropriate time periods that may include full market cycles, and compared to peer groups, as applicable, over the same periods, taking into account relevant factors including the following: general market conditions; issuer-specific information; and fund cash flows and other factors.

The Independent Trustees recognize that shareholders evaluate performance on a net basis over their own holding periods, for which one-, three-, and five-year periods are often used as a proxy. For this reason, the performance information reviewed by the Board also included net cumulative total return information for the fund and an appropriate benchmark index for the most recent one-year period ended September 30, 2021, as shown below.

Fidelity Disruptors Fund

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

Competitiveness of Management Fee and Total Expense Ratio. The Board considered the fund's management fee and total expense ratio compared to "mapped groups" of competitive funds and classes created for the purpose of facilitating the Trustees' competitive analysis of management fees and total expenses. Fidelity creates "mapped groups" by combining similar Lipper investment objective categories that have comparable investment mandates. Combining Lipper investment objective categories aids the Board's management fee and total expense ratio comparisons by broadening the competitive group used for comparison.

Management Fee. The Board considered two proprietary management fee comparisons for the period ended September 30 shown in basis points (BP) in the chart below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing in terms of gross management fees before expense reimbursements or caps relative to the total universe of funds with comparable investment mandates, regardless of whether their management fee structures also are comparable. Funds with comparable investment mandates offer exposure to similar types of securities. Funds with comparable management fee structures have similar management fee contractual arrangements (e.g., flat rate charged for advisory services, all-inclusive fee rate, etc.). "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than the fund's. For example, a hypothetical TMG % of 20% would mean that 80% of the funds in the Total Mapped Group had higher, and 20% had lower, management fees than the fund. The fund's actual TMG %s and the number of funds in the Total Mapped Group are in the chart below. The "Asset-Sized Peer Group" (ASPG) comparison focuses on a fund's standing relative to a subset of non-Fidelity funds within the Total Mapped Group that are similar in size and management fee structure. For example, if a fund is in the first quartile of the ASPG, the fund's management fee ranks in the least expensive or lowest 25% of funds in the ASPG. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee structures, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which the fund's management fee rate ranked is also included in the chart and was considered by the Board.

Fidelity Disruptors Fund

The Board noted that the fund's management fee rate ranked above the median of its Total Mapped Group and above the median of its ASPG for the period ended September 30, 2021. The Board considered that the fund has a unitary fee that covers expenses beyond advisory services, whereas the majority of funds within the fund's Total Mapped Group and ASPG do not have management fees that cover non-advisory services and fees. When compared to the total expenses of the fund's competitors, the fund is below median.

Based on its review, the Board concluded that the fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.

Total Expense Ratio. In its review of the total expense ratio of the representative class (retail class), the Board considered the fund's unitary fee rate as well as other fund expenses paid by FMR under the fund's management contract, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. The Board also noted that Fidelity may agree to waive fees or reimburse expenses from time to time, and the extent to which, if any, it has done so for the fund. The fund is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure. The Board also considered a total expense ASPG comparison for the fund, which focuses on the total expenses of the fund relative to a subset of non-Fidelity funds within the total expense similar sales load structure group. The total expense ASPG is limited to 15 larger and 15 smaller classes in fund average assets for a total of 30 classes, where possible. The total expense ASPG comparison excludes performance adjustments and fund-paid 12b-1 fees to eliminate variability in fee structures.

The Board noted that the fund's total net expense ratio ranked below the similar sales load structure group competitive median and below the ASPG competitive median for the period ended September 30, 2021.

The Board considered that current contractual arrangements for the fund oblige FMR to pay all "class-level" expenses of each class of each fund to the extent necessary to limit total operating expenses, with certain exceptions, as follows: Loyalty Class 1: 0.75% and Loyalty Class 2: 0.50%. These contractual arrangements may not be amended to increase the fees or expenses payable except by a vote of a majority of the Board.

Based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that the total expense ratio of each class of the fund was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability. The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and servicing the fund's shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

On an annual basis, Fidelity presents to the Board information about the profitability of its relationships with the fund. Fidelity calculates profitability information for each fund, as well as aggregate profitability information for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the books and records of Fidelity on which Fidelity's audited financial statements are based. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies and the full Board approves such changes.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund and was satisfied that the profitability was not excessive.

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale as assets grow through increased services to the fund, through waivers or reimbursements, or through fee or expense ratio reductions. The Board recognized that, due to the fund's current contractual arrangements, its expense ratio will not decline if the fund's operating costs decrease as assets grow, or rise as assets decrease. The Board also noted that a committee (the Economies of Scale Committee) created by it and the boards of other Fidelity funds periodically analyzes whether Fidelity attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.

Liquidity Risk Management Program

Notes to Financial Statements

For the period ended May 31, 2022

1. Organization.

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

2. Investments in Fidelity Central Funds.

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

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

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 – unadjusted quoted prices in active markets for identical investments
Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the 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)ADRs, futures contracts, 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.

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 May 31, 2022 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. Commissions paid to certain brokers with whom the investment adviser, or its affiliates, places trades on behalf of a fund include an amount in addition to trade execution, which may be rebated back to a fund. Any such rebates are included in net realized gain (loss) on investments in the Statement of Operations. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the 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. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain. Funds may file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld. Any withholding tax reclaims income is included in the Statement of Operations in dividends. Any receivables for withholding tax reclaims are included in the Statement of Assets and Liabilities in dividends receivable.

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 foreign currency transactions, capital loss carryforwards 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	$12,545
Gross unrealized depreciation	(82,421)
Net unrealized appreciation (depreciation)	$(69,876)
Tax Cost	$1,006,657

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

Undistributed ordinary income	$786
Capital loss carryforward	$(6,255)
Net unrealized appreciation (depreciation) on securities and other investments	$(69,876)

Capital loss carryforwards are only available to offset future capital gains of the Fund to the extent provided by regulations and may be limited. The capital loss carryforward information presented below, including any applicable limitation, is estimated as of fiscal period end and is subject to adjustment.

Short-term	$(6,255)
Total capital loss carryforward	$(6,255)

4. Purchases and Sales of Investments.

6. Expense Reductions.

This reimbursement will remain in place through September 30, 2023. 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 $31,573.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Summer Street Trust and Shareholders of Fidelity SAI Sustainable U.S. Equity Fund

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Fidelity SAI Sustainable U.S. Equity Fund (one of the funds constituting Fidelity Summer Street Trust, referred to hereafter as the “Fund”) as of May 31, 2022, and the related statements of operations and changes in net assets, including the related notes, and the financial highlights for the period April 14, 2022 (commencement of operations) through May 31, 2022 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of May 31, 2022, and the results of its operations, changes in its net assets, and the financial highlights for the period April 14, 2022 (commencement of operations) through May 31, 2022 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements 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 of these financial statements 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 are free of material misstatement, whether due to error or fraud.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, 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. 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. Our procedures included confirmation of securities owned as of May 31, 2022 by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audit provides a reasonable basis for our opinion.

We have served as the auditor of one or more investment companies in the Fidelity group of funds since 1932.

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 1-800-544-3455.

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. Robert A. Lawrence is an interested person and currently serves as Chair. The Trustees have determined that an interested Chair is appropriate and benefits shareholders because an interested Chair 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 Chair, 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 Chair 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. David M. Thomas serves as Lead Independent Trustee 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.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity SAI Sustainable U.S. Equity Fund

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

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

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

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

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

Competitiveness of Management Fee and Total Expense Ratio ..In reviewing the Advisory Contracts, the Board considered the fund's proposed management fee rate and the projected total expense ratio of the fund. The Board noted that the fund's proposed management fee rate is below the median fee rate of funds with similar Lipper investment objective categories and comparable investment mandates, regardless of whether their management fee structures are comparable. The Board also considered that the projected total expense ratio of the fund is below the median of those funds and classes used by the Board for management fee comparisons that have a similar sales load structure.

The Board also noted that FMR has contractually agreed to reimburse the fund to the extent that total operating expenses (excluding interest, certain taxes, fees and expenses of the Independent Trustees, proxy and shareholder meeting expenses, extraordinary expenses, and acquired fund fees and expenses (including fees and expenses associated with a wholly owned subsidiary), if any, as well as non-operating expenses such as brokerage commissions and fees and expenses associated with the fund's securities lending program, if applicable), as a percentage of its average net assets exceed 0.60% through September 30, 2023.

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

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

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

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

Notes to Financial Statements

For the period ended May 31, 2022

1. Organization.

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

2. Investments in Fidelity Central Funds.

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

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

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 – unadjusted quoted prices in active markets for identical investments
Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the 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, 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.

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 May 31, 2022 is included at the end of the Fund's Schedule of Investments.

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 foreign currency transactions and capital loss carryforwards.

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	$6,199
Gross unrealized depreciation	(70,813)
Net unrealized appreciation (depreciation)	$(64,614)
Tax Cost	$998,617

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

Undistributed ordinary income	$682
Capital loss carryforward	$(1,915)
Net unrealized appreciation (depreciation) on securities and other investments	$(64,614)

No expiration
Short-term	$(1,915)

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Summer Street Trust and Shareholders of Fidelity SAI Sustainable Future Fund

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Fidelity SAI Sustainable Future Fund (one of the funds constituting Fidelity Summer Street Trust, referred to hereafter as the “Fund”) as of May 31, 2022, and the related statements of operations and changes in net assets, including the related notes, and the financial highlights for the period April 14, 2022 (commencement of operations) through May 31, 2022 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of May 31, 2022, and the results of its operations, changes in its net assets, and the financial highlights for the period April 14, 2022 (commencement of operations) through May 31, 2022 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, 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. 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. Our procedures included confirmation of securities owned as of May 31, 2022 by correspondence with the custodian. We believe that our audit provides a reasonable basis for our opinion.

/s/ PricewaterhouseCoopers LLP

Boston, Massachusetts

July 15, 2022

We have served as the auditor of one or more investment companies in the Fidelity group of funds since 1932.

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 1-800-544-3455.

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. Robert A. Lawrence is an interested person and currently serves as Chair. The Trustees have determined that an interested Chair is appropriate and benefits shareholders because an interested Chair 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 Chair, 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 Chair 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. David M. Thomas serves as Lead Independent Trustee 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.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity SAI Sustainable Future Fund

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

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

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

Notes to Financial Statements

For the period ended May 31, 2022

1. Organization.

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

2. Investments in Fidelity Central Funds.

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

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

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 – unadjusted quoted prices in active markets for identical investments
Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the 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, 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.

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 May 31, 2022 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. Commissions paid to certain brokers with whom the investment adviser, or its affiliates, places trades on behalf of a fund include an amount in addition to trade execution, which may be rebated back to a fund. Any such rebates are included in net realized gain (loss) on investments in the Statement of Operations. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the 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. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain. Funds may file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld. Any withholding tax reclaims income is included in the Statement of Operations in dividends. Any receivables for withholding tax reclaims are included in the Statement of Assets and Liabilities in dividends receivable.

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 foreign currency transactions, capital loss carryforwards 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	$21,057
Gross unrealized depreciation	(147,466)
Net unrealized appreciation (depreciation)	$(126,409)
Tax Cost	$1,999,141

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

Undistributed ordinary income	$1,849
Capital loss carryforward	$(4,821)
Net unrealized appreciation (depreciation) on securities and other investments	$(126,409)

Short-term	$(4,821)
Total capital loss carryforward	$(4,821)

4. Purchases and Sales of Investments.

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

	Purchases ($)	Sales ($)
Fidelity SAI Sustainable Sector Fund	2,040,541	57,424

Fidelity SAI Sustainable Sector Fund	$16

	Purchases ($)	Sales ($)	Realized Gain (Loss) ($)
Fidelity SAI Sustainable Sector Fund	4,558	973	4

6. Expense Reductions.

The investment adviser contractually agreed to reimburse the Fund to the extent annual operating expenses exceeded .50% of average net assets. This reimbursement will remain in place through September 30, 2023. 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 $31,697.

7. Other.

At the end of the period, the investment adviser or its affiliates were owners of record of more than 10% of the outstanding shares as follows:

Fund	Affiliated %
Fidelity SAI Sustainable Sector Fund	100%

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Summer Street Trust and Shareholders of Fidelity SAI Sustainable Sector Fund

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Fidelity SAI Sustainable Sector Fund (one of the funds constituting Fidelity Summer Street Trust, referred to hereafter as the “Fund”) as of May 31, 2022, and the related statements of operations and changes in net assets, including the related notes, and the financial highlights for the period April 14, 2022 (commencement of operations) through May 31, 2022 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of May 31, 2022, and the results of its operations, changes in its net assets, and the financial highlights for the period April 14, 2022 (commencement of operations) through May 31, 2022 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, 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. 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. Our procedures included confirmation of securities owned as of May 31, 2022 by correspondence with the custodian. We believe that our audit provides a reasonable basis for our opinion.

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 1-800-544-3455.

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. Robert A. Lawrence is an interested person and currently serves as Chair. The Trustees have determined that an interested Chair is appropriate and benefits shareholders because an interested Chair 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 Chair, 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 Chair 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. David M. Thomas serves as Lead Independent Trustee 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.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity SAI Sustainable Sector Fund

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

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

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

Management's Discussion of Fund Performance

Comments from Portfolio Manager Asher Anolic: From inception on June 15, 2021, through May 31, 2022, the fund's share classes (excluding sales charges, if applicable) returned roughly -11%, underperforming the -6.97% result of its benchmark, the MSCI World Climate Change Index. We look to invest in stocks of climate-aware companies that are working to address climate change or its impacts either indirectly through their corporate strategy, or directly through the technology, services or products they provide. Versus the MSCI index, security selection in the consumer discretionary sector detracted most from the fund’s performance, especially our decision to avoid Apple, a large index component. Shares of the consumer electronics company gained about 15% during the reporting period, making it the fund’s biggest individual detractor. Apple did not fit our investment profile during the period. Elsewhere, stock choices in consumer staples hurt, as did an overweight in industrials. Among other individual stocks, larger-than-index positions in Etsy (-60%), the online retailer of handmade or vintage items, French luxury apparel and accessories brand owner Kering (-38%) and Spanish wireless telecom infrastructure and services firm Cellnex Telecom (-29%) weighed on the fund's relative result. Conversely, positioning in the communication services sector notably contributed to the fund's relative performance. Stock selection in real estate also added relative value. The fund's biggest individual relative contributor was not owning index component Amazon.com (-29%), an e-commerce company. Overweighting health care services firm Anthem (+21%) and Belgium-based utilities company Elia Group (+34%) also added value versus the benchmark this period.

Notes to Financial Statements

For the period ended May 31, 2022

1. Organization.

Fidelity Climate Action Fund (the Fund) is a fund of Fidelity Summer 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. The Fund offers Class A, Class M, Class C, Climate Action, Class I and Class Z shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Effective June 21, 2021, Class C shares will automatically convert to Class A shares after a holding period of eight years from the initial date of purchase, with certain exceptions. Prior to June 21, 2021, Class C shares automatically converted to Class A shares after a holding period of ten years from the initial date of purchase, with certain exceptions. Because the Fund focuses its investments in equity securities of climate aware companies, it will be more susceptible to events or factors affecting these companies. The Fund is particularly exposed to such developments as changes in global and regional climates, environmental protection regulatory actions, changes in government standards and subsidy levels, changes in taxation and other domestic and international political, regulatory, and economic developments. Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance depending on whether certain investments are in or out of favor. The criteria related to the Fund's ESG ratings process and/or adherence to its sustainable investing exclusion criteria may result in the Fund forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so, or selling securities for ESG reasons when it might be otherwise disadvantageous for it to do so. As a result, the Fund's performance may at times be better or worse than the performance of funds that do not use ESG or sustainability criteria. There are significant differences in interpretations of what it means for an issuer to have positive ESG factors. While the investment adviser believes its definitions are reasonable, the portfolio decisions it makes may differ with other investors' or advisers' views.

2. Investments in Fidelity Central Funds.

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

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

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 – unadjusted quoted prices in active markets for identical investments
Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the 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.

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 May 31, 2022 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. Commissions paid to certain brokers with whom the investment adviser, or its affiliates, places trades on behalf of a fund include an amount in addition to trade execution, which may be rebated back to a fund. Any such rebates are included in net realized gain (loss) on investments in the Statement of Operations. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the 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. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain. Funds may file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld. Any withholding tax reclaims income is included in the Statement of Operations in foreign tax reclaims. Any receivables for withholding tax reclaims are included in the Statement of Assets and Liabilities in reclaims receivable.

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 foreign currency transactions, capital loss carryforwards 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	$580,773
Gross unrealized depreciation	(3,064,497)
Net unrealized appreciation (depreciation)	$(2,483,724)
Tax Cost	$22,645,714

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

Undistributed ordinary income	$2,652
Capital loss carryforward	$(1,440,770)
Net unrealized appreciation (depreciation) on securities and other investments	$(2,483,791)

Short-term	$(1,437,874)
Long-term	(2,896)
Total capital loss carryforward	$(1,440,770)

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

4. Purchases and Sales of Investments.

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

	Purchases ($)	Sales ($)
Fidelity Climate Action Fund	33,234,620	9,346,913

5. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company LLC (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 the sum of an individual fund fee rate that is based on an annual rate of .45% of the Fund's average net assets and an annualized group fee rate that averaged .22% during the period. The group fee rate is based upon the monthly average net assets of a group of registered investment companies with which the investment adviser has management contracts. The group fee rate decreases as assets under management increase and increases as assets under management decrease. In addition, the management fee is subject to a performance adjustment (up to a maximum of +/- .10% of the Fund's average net assets over a 36 month performance period). The upward or downward adjustment to the management fee is based on the relative investment performance of Climate Action as compared to its benchmark index, the MSCI World Index, over the same 36 month performance period. The Fund's performance adjustment will not take effect until June 1, 2022. Subsequent months will be added until the performance period includes 36 months. For the reporting period, the total annualized management fee rate was .68% of the Fund's average net assets.

Distribution and Service Plan Fees. In accordance with Rule 12b-1 of the 1940 Act, the Fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Company LLC (FDC), an affiliate of the investment adviser, separate Distribution and Service Fees, each of which is based on an annual percentage of each class' average net assets. In addition, FDC may pay financial intermediaries for selling shares of the Fund and providing shareholder support services. For the period, the Distribution and Service Fee rates, total fees and amounts retained by FDC were as follows:

	Distribution Fee	Service Fee	Total Fees	Retained by FDC
Class A	-%	.25%	$752	$245
Class M	.25%	.25%	730	489
Class C	.75%	.25%	2,548	2,422
			$4,030	$3,156

Sales Load. FDC may receive a front-end sales charge of up to 5.75% for selling Class A shares and 3.50% for selling Class M shares, some of which is paid to financial intermediaries for selling shares of the Fund. Depending on the holding period, FDC may receive contingent deferred sales charges levied on Class A, Class M and Class C redemptions. The deferred sales charges are 1.00% for Class C shares, 1.00% for certain purchases of Class A shares and .25% for certain purchases of Class M shares.

For the period, sales charge amounts retained by FDC were as follows:

	Retained by FDC
Class A	$198
Class M	2
	$200

Transfer Agent Fees. Fidelity Investments Institutional Operations Company LLC (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of the respective classes of the Fund, except for Class Z. FIIOC receives an asset-based fee of Class Z's average net assets. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements.

For the period, transfer agent fees for each class were as follows:

	Amount	% of Class-Level Average Net Assets^(a)
Class A	$640	.21
Class M	200	.14
Class C	379	.15
Fidelity Climate Action Fund	41,962	.28
Class I	233	.15
Class Z	45	.04
	$43,459

(a) Annualized

Accounting Fees. Fidelity Service Company, Inc. (FSC), an affiliate of the investment adviser, maintains the Fund's accounting records. The accounting fee is based on the level of average net assets for each month. For the period, the fees were equivalent to the following annualized rates:

	% of Average Net Assets
Fidelity Climate Action Fund	.04

	Amount
Fidelity Climate Action Fund	$179

	Purchases ($)	Sales ($)	Realized Gain (Loss) ($)
Fidelity Climate Action Fund	538,162	252,732	(25,789)

6. Committed Line of Credit.

	Amount
Fidelity Climate Action Fund	$1

7. Expense Reductions.

The investment adviser contractually agreed to reimburse expenses of each class to the extent annual operating expenses exceeded certain levels of class-level average net assets as noted in the table below. This reimbursement will remain in place through September 30, 2023. Some expenses, for example the compensation of the independent Trustees are excluded from this reimbursement.

The following classes were in reimbursement during the period:

	Expense Limitations	Reimbursement
Class A	1.30%	$4,946
Class M	1.55%	2,602
Class C	2.05%	3,821
Fidelity Climate Action Fund	1.05%	246,428
Class I	1.05%	2,857
Class Z	.90%	2,275
		$262,929

In addition, during the period the investment adviser or an affiliate reimbursed and/or waived a portion of fund-level operating expenses in the amount of $415.

8. Share Transactions.

Share transactions for each class were as follows and may contain in-kind transactions, automatic conversions between classes or exchanges between affiliated funds:

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Summer Street Trust and Shareholders of Fidelity Climate Action Fund

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Fidelity Climate Action Fund (the "Fund"), a fund of Fidelity Summer Street Trust, including the schedule of investments, as of May 31, 2022, the related statement of operations, the statement of changes in net assets and the financial highlights for the period from June 15, 2021 (commencement of operations) through May 31, 2022, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of May 31, 2022, the results of its operations, the changes in its net assets and the financial highlights for the period from June 15, 2021 (commencement of operations) through May 31, 2022, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the 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 May 31, 2022, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audit 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 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 if you’re an individual investing directly with Fidelity, call 1-800-835-5092 if you’re a plan sponsor or participant with Fidelity as your recordkeeper or call 1-877-208-0098 on institutional accounts or if you’re an advisor or invest through one.

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. Robert A. Lawrence is an interested person and currently serves as Chair. The Trustees have determined that an interested Chair is appropriate and benefits shareholders because an interested Chair 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 Chair, 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 Chair 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. David M. Thomas serves as Lead Independent Trustee 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.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Climate Action Fund

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract with Fidelity Management & Research Company LLC (FMR) and the sub-advisory agreements (together, the Advisory Contracts) for the fund. FMR and the sub-advisers are referred to herein as the Investment Advisers. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and, at each of its meetings, covers an extensive agenda of topics and materials and considers factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board has established various standing committees (Committees), each composed of and chaired by Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of the fund's Advisory Contracts. The Board also meets as needed to review matters specifically related to the Board's annual consideration of the renewal of the Advisory Contracts. Members of the Board may also meet with trustees of other Fidelity funds through joint ad hoc committees to discuss certain matters relevant to all of the Fidelity funds.

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

Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians, subcustodians, and pricing vendors; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures. The Board also reviewed the allocation of fund brokerage, including allocations to brokers affiliated with the Investment Advisers, the use of brokerage commissions to pay fund expenses, and the use of "soft" commission dollars to pay for research services.

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

Investment Performance. The Board considered whether the fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions. As the fund recently commenced operations, the Board did not believe that it was appropriate to assign significant weight to its limited investment performance history.

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

Management Fee. The Board considered two proprietary management fee comparisons for the period of the fund's operations shown in basis points (BP) in the chart below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing in terms of gross management fees before expense reimbursements or caps, and without giving effect to the fund's performance adjustment, relative to the total universe of funds with comparable investment mandates, regardless of whether their management fee structures also are comparable. Funds with comparable investment mandates offer exposure to similar types of securities. Funds with comparable management fee structures have similar management fee contractual arrangements (e.g., flat rate charged for advisory services, all-inclusive fee rate, etc.). "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than the fund's. For example, a hypothetical TMG % of 20% would mean that 80% of the funds in the Total Mapped Group had higher, and 20% had lower, management fees than the fund. The fund's actual TMG % and the number of funds in the Total Mapped Group are in the chart below. The "Asset-Sized Peer Group" (ASPG) comparison focuses on a fund's standing relative to a subset of non-Fidelity funds within the Total Mapped Group that are similar in size and management fee structure without taking into account performance adjustments, if any. For example, if a fund is in the first quartile of the ASPG, the fund's management fee ranks in the least expensive or lowest 25% of funds in the ASPG. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee structures, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which the fund's management fee rate ranked and the impact of the fund's performance adjustment, is also included in the chart and was considered by the Board.

Fidelity Climate Action Fund

The Board noted that the fund's management fee rate ranked below the median of its Total Mapped Group and below the median of its ASPG for the 12-month period ended September 30, 2021. The Board also noted the effect of the fund's performance adjustment, if any, on the fund's management fee ranking.

Based on its review, the Board concluded that the fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.

Total Expense Ratio. In its review of the total expense ratio of the representative class (retail class), the Board considered the fund's management fee rate as well as other fund or class expenses, as applicable, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. The Board noted the impact of the fund's performance adjustment. The Board also noted that Fidelity may agree to waive fees or reimburse expenses from time to time, and the extent to which, if any, it has done so for the fund. The fund's representative class is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure. The Board also considered a total expense ASPG comparison for the representative class, which focuses on the total expenses of the representative class relative to a subset of non-Fidelity funds within the total expense similar sales load structure group. The total expense ASPG is limited to 15 larger and 15 smaller classes in fund average assets for a total of 30 classes, where possible. The total expense ASPG comparison excludes performance adjustments and fund-paid 12b-1 fees to eliminate variability in fee structures.

The Board noted that the total net expense ratio of the retail class ranked below the similar sales load structure group competitive median and above the ASPG competitive median for the 12-month period ended September 30, 2021. The Board considered that, in general, various factors can affect total expense ratios. The Board also considered that Fidelity believes that, because the ASPG is composed of funds/classes with varied types of servicing arrangements, such funds/classes are not directly comparable to the retail class of the fund.

The Board further considered that FMR has contractually agreed to reimburse Class A, Class M, Class C, Class I, Class Z, and the retail class of the fund to the extent that total operating expenses, with certain exceptions, as a percentage of their respective average net assets, exceed 1.30%, 1.55%, 2.05%, 1.05%, 0.90%, and 1.05% through September 30, 2022.

Costs of the Services and Profitability. The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and servicing the fund's shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale as assets grow through increased services to the fund, through waivers or reimbursements, or through fee or expense ratio reductions. The Board also noted that a committee (the Economies of Scale Committee) created by it and the boards of other Fidelity funds periodically analyzes whether Fidelity attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board recognized that the fund's management contract incorporates a "group fee" structure, which provides for lower group fee rates as total "group assets" increase, and for higher group fee rates as total "group assets" decrease ("group assets" as defined in the management contract). FMR calculates the group fee rates based on a tiered asset "breakpoint" schedule that varies based on asset class. The Board considered that the group fee is designed to deliver the benefits of economies of scale to fund shareholders when total Fidelity fund assets increase, even if assets of any particular fund are unchanged or have declined, because some portion of Fidelity's costs are attributable to services provided to all Fidelity funds, and all funds benefit if those costs can be allocated among more assets. The Board further considered that Fidelity agreed to impose a temporary fee waiver in the form of additional breakpoints to the current breakpoint schedule. The Board concluded that, given the group fee structure, fund shareholders will benefit from lower management fees as "group assets" increase at the fund complex level, regardless of whether Fidelity achieves any such economies of scale.

The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' advisory contracts, the Board requested and received additional information on certain topics, including: (i) fund flow and performance trends, in particular the underperformance of certain funds and strategies, and Fidelity's long-term strategies for certain funds, including any consideration of fund liquidations or mergers; (ii) the operation of performance fees, competitor use of performance fees and consideration of the expansion of performance fees to additional funds; (iii) Fidelity's pricing philosophy compared to competitors; (iv) fund profitability methodology and data; (v) evaluation of competitive fund data and peer group classifications and fee and expense comparisons; (vi) the management fee and expense structures for different funds and classes and information about the differences between various fee and expense structures; (vii) group fee breakpoints and related voluntary fee waivers; and (viii) information regarding other accounts managed by Fidelity and the funds' sub-advisory arrangements.

Management's Discussion of Fund Performance

Market Recap: The S&P 500^® index returned -0.30% for the 12 months ending May 31, 2022. Large-cap stocks retreated to begin the new year amid several notable headwinds that stoked volatility, uncertainty and anxiety. Chief among these was the U.S. Federal Reserve’s accelerated plan to hike interest rates and aggressively wind down its balance sheet to rein in historically high inflation. In addition, geopolitical unrest rose as Russia invaded Ukraine in late February and escalated its attack through period end. Other factors influencing stocks included surging commodity prices, rising bond yields, supply constraint and disruption, and the potential for variants of the coronavirus to upend the U.S. economy. Against this backdrop, the S&P 500^® index returned -5.17% in January and -2.99% in February, falling on mixed corporate earnings, particularly among some highflying tech firms. In April, the index returned -8.72% amid clearer signals of the Fed’s intension to tighten monetary policy and angst about the economic toll of “zero-COVID” lockdowns in China. It was the largest monthly decline for the S&P 500^® since March 2020. In early May, the Fed approved a rare half-percentage-point interest rate increase and announced plans to shrink its $9 trillion asset portfolio starting in June. For the full 12 months, the growth-oriented communication services (-21%) and consumer discretionary (-12%) sectors lagged most. In contrast, energy (+76%) rode a surge in commodity prices and led, followed by utilities (+18%).

Comments from Co-Portfolio Managers Nicole Connolly and Michael Robertson: Since inception on June 15, 2021, through May 31, 2022, the fund's share classes (excluding sales charges, if applicable) returned roughly -5% to -6%, trailing the -3.48% result of the MSCI USA IMI ESG Leaders Index and the -5.08% result of the Russell 3000^® Index. Versus the MSCI ESG index, stock selection in the consumer discretionary sector notably detracted, especially in the retailing industry. Picks in the software & services segment of the information technology sector also hurt relative performance this period. In retailing, an overweight position in apparel retailer Gap (-65%) was the fund's largest individual relative detractor. In software & services, larger-than-index stakes in digital payments provider PayPal Holdings (-69%) and cloud-based software firm Salesforce (-34%) also notably held back the fund's relative result. The fund's foreign holdings detracted overall, hampered in part by continued U.S. dollar strength. Conversely, stock selection and an overweighting in energy contributed to the fund's relative performance, as did positioning in the semiconductors & semiconductor equipment industry within the information technology sector. Underweighting the communications services sector also helped. An overweight position in ON Semiconductor (+64%) boosted relative performance more than any other individual investment this period. A higher-than-index position in refining firm Valero Energy (+62%) also notably contributed. Not owning a position in index component Meta Platforms also helped our relative result, as the stock returned about -43%.

Notes to Financial Statements

For the period ended May 31, 2022

1. Organization.

Fidelity Sustainable U.S. Equity Fund (the Fund) (formerly Fidelity Sustainability U.S. Equity Fund) is a fund of Fidelity Summer 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. The Fund offers Class A, Class M, Class C, Fidelity Sustainable U.S. Equity Fund, Class I and Class Z shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Effective June 21, 2021, Class C shares will automatically convert to Class A shares after a holding period of eight years from the initial date of purchase, with certain exceptions. Prior to June 21, 2021, Class C shares automatically converted to Class A shares after a holding period of ten years from the initial date of purchase, with certain exceptions. Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance depending on whether certain investments are in or out of favor. The criteria related to the Fund's ESG ratings process and/or adherence to its sustainable investing exclusion criteria may result in the Fund forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so, or selling securities for ESG reasons when it might be otherwise disadvantageous for it to do so. As a result, the Fund's performance may at times be better or worse than the performance of funds that do not use ESG or sustainability criteria. There are significant differences in interpretations of what it means for an issuer to have positive ESG factors. While the investment adviser believes its definitions are reasonable, the portfolio decisions it makes may differ with other investors' or advisers' views.

2. Investments in Fidelity Central Funds.

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

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

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 – unadjusted quoted prices in active markets for identical investments
Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the 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, 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.

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 May 31, 2022 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. Commissions paid to certain brokers with whom the investment adviser, or its affiliates, places trades on behalf of a fund include an amount in addition to trade execution, which may be rebated back to a fund. Any such rebates are included in net realized gain (loss) on investments in the Statement of Operations. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the 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. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain. Funds may file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld. Any withholding tax reclaims income is included in the Statement of Operations in dividends. Any receivables for withholding tax reclaims are included in the Statement of Assets and Liabilities in dividends receivable.

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 foreign currency transactions, 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	$709,375
Gross unrealized depreciation	(2,319,659)
Net unrealized appreciation (depreciation)	$(1,610,284)
Tax Cost	$17,583,246

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

Undistributed ordinary income	$10,127
Net unrealized appreciation (depreciation) on securities and other investments	$(1,610,349)

The Fund intends to elect to defer to its next fiscal year $312,835 of capital losses recognized during the period November 1, 2021 to May 31, 2022.

Due to large subscriptions in the period, Fidelity Sustainability U.S. Equity Fund is subject to an annual limit on its use of some of its unrealized capital losses to offset capital gains in future periods. If those losses are realized and the limitation prevents the Fund from using any of those losses in a future period, those capital losses will be available to offset capital gains in subsequent periods.

The tax character of distributions paid was as follows:

	May 31, 2022^(a)
Ordinary Income	$58,306
Total	$58,306

(a) For the period June 15, 2021 (commencement of operations) through May 31, 2022.

4. Purchases and Sales of Investments.

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

	Purchases ($)	Sales ($)
Fidelity Sustainable U.S. Equity Fund	23,602,170	5,864,999

5. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company LLC (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 the sum of an individual fund fee rate that is based on an annual rate of .30% of the Fund's average net assets and an annualized group fee rate that averaged .22% during the period. The group fee rate is based upon the monthly average net assets of a group of registered investment companies with which the investment adviser has management contracts. The group fee rate decreases as assets under management increase and increases as assets under management decrease. In addition, the management fee is subject to a performance adjustment (up to a maximum of +/- .10% of the Fund's average net assets over a 36 month performance period). The upward or downward adjustment to the management fee is based on the relative investment performance of Fidelity Sustainable U.S. Equity Fund as compared to its benchmark index, the Russell 3000 Index, over the same 36 month performance period. The Fund's performance adjustment will not take effect until June 1, 2022. Subsequent months will be added until the performance period includes 36 months. For the reporting period, the total annualized management fee rate was .53% of the Fund's average net assets.

	Distribution Fee	Service Fee	Total Fees	Retained by FDC
Class A	-%	.25%	$907	$616
Class M	.25%	.25%	876	515
Class C	.75%	.25%	1,612	1,357

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Summer Street Trust and Shareholders of Fidelity Sustainable U.S. Equity Fund

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying statement of assets and liabilities of Fidelity Sustainable U.S. Equity Fund (formerly Fidelity Sustainability U.S. Equity Fund)(the "Fund"), a fund of Fidelity Summer Street Trust, including the schedule of investments, as of May 31, 2022, the related statement of operations, the statement of changes in net assets and the financial highlights for the period from June 15, 2021 (commencement of operations) through May 31, 2022, and the related notes. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of May 31, 2022, the results of its operations, the changes in its net assets and the financial highlights for the period from June 15, 2021 (commencement of operations) through May 31, 2022, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the 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.

/s/ Deloitte & Touche LLP

Boston, Massachusetts

July 14, 2022

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. Robert A. Lawrence is an interested person and currently serves as Chair. The Trustees have determined that an interested Chair is appropriate and benefits shareholders because an interested Chair 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 Chair, 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 Chair 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. David M. Thomas serves as Lead Independent Trustee 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.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Sustainable U.S. Equity Fund (formerly known as Fidelity Sustainability U.S. Equity Fund)

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract with Fidelity Management & Research Company LLC (FMR) and the sub-advisory agreements (together, the Advisory Contracts) for the fund. FMR and the sub-advisers are referred to herein as the Investment Advisers. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and, at each of its meetings, covers an extensive agenda of topics and materials and considers factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board has established various standing committees (Committees), each composed of and chaired by Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of the fund's Advisory Contracts. The Board also meets as needed to review matters specifically related to the Board's annual consideration of the renewal of the Advisory Contracts. Members of the Board may also meet with trustees of other Fidelity funds through joint ad hoc committees to discuss certain matters relevant to all of the Fidelity funds.

At its May 2022 meeting, the Board unanimously determined to renew the fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness relative to peer funds of the fund's management fee and total expense ratio of a representative class (retail class); (iii) the total costs of the services provided by and the profits realized by Fidelity from its relationships with the fund; and (iv) the extent to which, if any, economies of scale exist and are realized as the fund grows, and whether any economies of scale are appropriately shared with fund shareholders.

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

Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians, subcustodians, and pricing vendors; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures. The Board also reviewed the allocation of fund brokerage, including allocations to brokers affiliated with the Investment Advisers, the use of brokerage commissions to pay fund expenses, and the use of "soft" commission dollars to pay for research services.

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

Investment Performance. The Board considered whether the fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions. As the fund recently commenced operations, the Board did not believe that it was appropriate to assign significant weight to its limited investment performance.

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

Management Fee. The Board considered two proprietary management fee comparisons for the period of the fund's operations ended September 30 shown in basis points (BP) in the chart below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing in terms of gross management fees before expense reimbursements or caps, relative to the total universe of funds with comparable investment mandates, regardless of whether their management fee structures also are comparable. Funds with comparable investment mandates offer exposure to similar types of securities. Funds with comparable management fee structures have similar management fee contractual arrangements (e.g., flat rate charged for advisory services, all-inclusive fee rate, etc.). "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than the fund's. For example, a hypothetical TMG % of 20% would mean that 80% of the funds in the Total Mapped Group had higher, and 20% had lower, management fees than the fund. The fund's actual TMG % and the number of funds in the Total Mapped Group are in the chart below. The "Asset-Sized Peer Group" (ASPG) comparison focuses on a fund's standing relative to a subset of non-Fidelity funds within the Total Mapped Group that are similar in size and management fee structure. For example, if a fund is in the first quartile of the ASPG, the fund's management fee ranks in the least expensive or lowest 25% of funds in the ASPG. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee structures, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which the fund's management fee rate ranked, is also included in the chart and was considered by the Board.

Fidelity Sustainable U.S. Equity Fund

The Board noted that the fund's management fee rate ranked below the median of its Total Mapped Group and below the median of its ASPG for the period ended September 30, 2021.

Based on its review, the Board concluded that the fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.

Total Expense Ratio. In its review of the total expense ratio of the representative class (retail class), the Board considered the fund's management fee rate as well as other fund or class expenses, as applicable, such as transfer agent fees, pricing and bookkeeping fees, fund-paid 12b-1 fees, and custodial, legal, and audit fees. The Board also noted that Fidelity may agree to waive fees or reimburse expenses from time to time, and the extent to which, if any, it has done so for the fund. The fund's representative class is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure. The Board also considered a total expense ASPG comparison, which focuses on the total expenses of the representative class relative to a subset of non-Fidelity funds within the total expense similar sales load structure group. The total expense ASPG is limited to 15 larger and 15 smaller classes in fund average assets for a total of 30 classes, where possible. The total expense ASPG comparison excludes performance adjustments and fund-paid 12b-1 fees to eliminate variability in fee structures.

The Board noted that the total net expense ratio of the retail class ranked below the similar sales load structure group competitive median and below the ASPG competitive median for the period ended September 30, 2021. The Board considered that, in general, various factors can affect total expense ratios.

The Board further considered that FMR has contractually agreed to reimburse Class A, Class M, Class C, Class I, Class Z, and the retail class of the fund to the extent that total operating expenses, with certain exceptions, as a percentage of their respective average net assets, exceed 1.15%, 1.40%, 1.90%, 0.90%, 0.75%, and 0.90% through September 30, 2022.

Costs of the Services and Profitability. The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and servicing the fund's shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale as assets grow through increased services to the fund, through waivers or reimbursements, or through fee or expense ratio reductions. The Board also noted that a committee (the Economies of Scale Committee) created by it and the boards of other Fidelity funds periodically analyzes whether Fidelity attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.

The trust's Audit Committee has considered non-audit services that were not pre-approved that were provided by Deloitte Entities and PwC to Fund Service Providers to be compatible with maintaining the independence of Deloitte Entities and PwC in its(their) audit of the Fund(s), taking into account representations from Deloitte Entities and PwC, in accordance with Public Company Accounting Oversight Board rules, regarding its independence from the Fund(s) and its(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(s) 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 Fund’s(s’) last two fiscal years relating to services provided to (i) the Fund(s) or (ii) any Fund Service Provider that relate directly to the operations and financial reporting of the Fund(s).
