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.

Average Annual Total Returns

Fidelity® Growth Discovery Fund	25.08%	15.38%	8.21%

Management's Discussion of Fund Performance

Market Recap: The U.S. equity bellwether S&P 500^® index gained 17.90% for the year ending June 30, 2017, rising sharply following the November election and continuing to gain ground through the end of February on optimism for President Trump’s pro-business agenda. Equity markets leveled off, however, as the fledgling administration faced the first test of its domestic agenda. Stocks reacted with uncertainty to efforts by Congress in March to repeal and replace the Affordable Care Act, and then turned upward through June 30. Sector-wise, financials (+38%) fared best, riding an uptick in bond yields and a surge in bank shares, particularly post-election. Information technology (+34%) also did quite well, as a handful of major index constituents posted stellar returns. Industrials (+22%) and materials (+19%) were driven by a call for increased infrastructure spending and a rise in related commodity prices, respectively. Consumer discretionary (+17%) roughly index-performed, buoyed by e-commerce giants Amazon.com and Netflix. Conversely, telecommunication services (-12%) and real estate (0%) struggled amid an improved backdrop for riskier assets that curbed demand for dividend-rich sectors, as well as the likelihood of additional interest rate hikes later in 2017. Energy (-4%) lagged due to low oil prices.

Comments from Portfolio Manager Jason Weiner: For the year, the fund's share classes posted gains of about 25%, outperforming the 20.72% result of the Russell 3000^® Growth Index. Choices among consumer discretionary names helped the most by far from a sector perspective. Included was a large overweighting in cable-services giant Charter Communications, which rose 47% on consecutive quarters of mostly positive financial results following the company’s roughly $70 billion acquisition of Time Warner Cable – along with internet provider Bright House Networks – completed just prior the start of the period. In terms of individual stocks, social-media giant Facebook, the fund’s largest holding, was our biggest individual contributor the past 12 months. After tepid performance for most of 2016 – despite great financial results – the stock rallied along with the greater technology sector during the latter half of the period. Our Facebook holdings advanced about 31% for the full period. Turning to detractors, the fund was underweighted, on average, in consumer electronics giant Apple on growth concerns. This decision proved the fund's largest relative detractor this period, as Apple shares advanced about 54% on strong sales for its iPhone^® 7 device, along with excitement around the upcoming launch of its new iPhone^® 8. Positioning in industrials and a modest cash stake also detracted.

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

Notes to Financial Statements

For the period ended June 30, 2017
(Amounts in thousands except percentages)

1. Organization.

Fidelity Growth Discovery Fund (the Fund) is a fund of Fidelity Hastings 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 Growth Discovery and Class K 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.

2. Investments in Fidelity Central Funds.

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

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

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

3. Significant Accounting Policies.

The Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services – Investments Companies. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the Fund:

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

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

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

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

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. Utilizing these techniques may result in transfers between Level 1 and Level 2. 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 June 30, 2017 is included at the end of the Fund's Schedule of Investments.

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

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 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 and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the 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.

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

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 June 30, 2017, 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. Foreign taxes are provided for based on the 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 dividends 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.

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

Book-tax differences are primarily due to futures contracts, foreign currency transactions, market discount, partnerships, capital loss carryforwards, and losses deferred due to wash sales and excise tax regulations.

The federal tax cost of investment securities and unrealized appreciation (depreciation) as of period end were as follows:

Gross unrealized appreciation	$338,050
Gross unrealized depreciation	(19,154)
Net unrealized appreciation (depreciation) on securities	$318,896
Tax Cost	$1,078,049

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

Undistributed ordinary income	$1,292
Undistributed long-term capital gain	$33,657
Net unrealized appreciation (depreciation) on securities and other investments	$318,885

The tax character of distributions paid was as follows:

	June 30, 2017	June 30, 2016
Ordinary Income	$1,135	$ 2,344

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

4. Derivative Instruments.

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

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

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

Equity Risk

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

The Fund is also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that the Fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to the Fund. Counterparty credit risk related to exchange-traded futures contracts may be mitigated by the protection provided by the exchange on which they trade.

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

Futures Contracts. A futures contract is an agreement between two parties to buy or sell a specified underlying instrument for a fixed price at a specified future date. The Fund used futures contracts to manage its exposure to the stock market.

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

During the period the Fund recognized net realized gain (loss) of $635 related to its investment in futures contracts. This amount is included in the Statement of Operations.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $750,619 and $812,934, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee. Fidelity Management & Research Company (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund 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 .25% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by the investment adviser, including any mutual funds previously advised by the investment adviser that are currently advised by Fidelity SelectCo, LLC, an affiliate of the investment adviser. 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 +/- .20% 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 Growth Discovery as compared to its benchmark index, the Russell 3000 Growth Index, over the same 36 month performance period. For the reporting period, the total annual management fee rate, including the performance adjustment, was .44% of the Fund's average net assets. The performance adjustment included in the management fee rate may be higher or lower than the maximum performance adjustment rate due to the difference between the average net assets for the reporting and performance periods.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc., (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of Growth Discovery. FIIOC receives an asset-based fee of Class K'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
Growth Discovery	$1,724	.17
Class K	85	.05
	$1,809

Accounting and Security Lending 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. Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions.

Brokerage Commissions. The Fund placed a portion of its portfolio transactions with brokerage firms which are affiliates of the investment adviser. Brokerage commissions are included in net realized gain (loss) and change in net unrealized appreciation (depreciation) in the Statement of Operations. The commissions paid to these affiliated firms were $18 for the period.

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

Borrower or Lender	Average Loan Balance	Weighted Average Interest Rate	Interest Expense
Borrower	$5,529	.74%	$1

Interfund Trades. The Fund may purchase from or sell securities to other Fidelity Funds under procedures adopted by the Board. The procedures have been designed to ensure these interfund trades are executed in accordance with Rule 17a-7 of the 1940 Act. Interfund trades are included within the respective purchases and sales amounts shown in the Purchases and Sales of Investments note.

7. Committed Line of Credit.

The Fund participates with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $4 and is reflected in Miscellaneous expenses on the Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The Fund or borrower may terminate the loan at any time, and if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Fund may apply collateral received from the borrower against the obligation. The Fund may experience delays and costs in recovering the securities loaned. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. At period end, there were no security loans outstanding with FCM. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Total security lending income during the period amounted to $552, including $28 from securities loaned to FCM.

9. Expense Reductions.

In addition, during the period the investment adviser reimbursed and/or waived a portion of fund-level operating expenses in the amount of $10.

10. Distributions to Shareholders.

Distributions to shareholders of each class were as follows:

	Year ended June 30, 2017	Year ended June 30, 2016
From net investment income
Growth Discovery	$880	$1,330
Class K	255	459
Total	$1,135	$1,789
From net realized gain
Growth Discovery	$–	$471
Class K	–	84
Total	$–	$555

11. Share Transactions.

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

	Shares	Shares	Dollars	Dollars
	Year ended June 30, 2017	Year ended June 30, 2016	Year ended June 30, 2017	Year ended June 30, 2016

Net increase (decrease)	(423)	(899)	$(9,315)	$(22,109)

12. Other.

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

Report of Independent Registered Public Accounting Firm

To the Trustees of Fidelity Hastings Street Trust and Shareholders of Fidelity Growth Discovery Fund:

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Fidelity Growth Discovery Fund (a fund of Fidelity Hastings Street Trust) as of June 30, 2017, 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 five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fidelity Growth Discovery Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of June 30, 2017 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.

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. Each of the Trustees oversees 189 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.

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

Fidelity^® funds are overseen by different Boards of Trustees. The fund's Board oversees Fidelity's high income and certain equity funds, and other Boards oversee Fidelity's investment-grade bond, money market, asset allocation, and sector 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. In addition, the Independent Trustees have worked with FMR to enhance the Board's oversight of investment and financial risks, legal and regulatory risks, technology risks, and operational risks, including the development of additional risk reporting to the Board. For example, a working group comprised of Independent Trustees and FMR has worked and continues to work to review the Fidelity^® funds' valuation-related activities, reporting and risk management. Appropriate personnel, including but not limited to the fund's Chief Compliance Officer (CCO), FMR's internal auditor, the independent accountants, the fund's Treasurer and portfolio management personnel, make periodic reports to the Board's committees, as appropriate, including an annual review of Fidelity's risk management program for the Fidelity^® funds. The responsibilities of each standing committee, including their oversight responsibilities, are described further under "Standing Committees of the Trustees."

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (January 1, 2017 to June 30, 2017).

Actual Expenses

The first line of the accompanying table for each class of the Fund provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class of the Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table for each class of the Fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' 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. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

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

	Annualized Expense Ratio-^A	Beginning Account Value January 1, 2017	Ending Account Value June 30, 2017	Expenses Paid During Period-^B January 1, 2017 to June 30, 2017
Growth Discovery	.65%
Actual		$1,000.00	$1,203.00	$3.55
Hypothetical-^C		$1,000.00	$1,021.57	$3.26

Management's Discussion of Fund Performance

Comments from Portfolio Manager Matthew Fruhan: For the fiscal year, the fund gained 21.18%, significantly outpacing the benchmark S&P 500^®. The fund benefited most from strong stock picking in the financials sector and a sizable overweight in banks – the strongest-performing industry in the index the past 12 months. I’ve emphasized banks in the fund for some time, and I’m pleased my patience and willingness to be contrarian with this investment was rewarded this period. In financials, Bank of America, JPMorgan Chase and Citigroup, all among the fund’s largest holdings and top contributors, led the way. Elsewhere, security selection in energy was helpful, although the positive impact was offset by a large overweight in the lagging sector. Here, the fund benefited from my decision to avoid Exxon Mobil, a large index component whose shares returned about -11%. Conversely, unfavorable positioning within information technology hampered results, as did stock picking in health care. The biggest individual detractors were a non-benchmark position in Israel-based drugmaker Teva Pharmaceutical Industries and an overweight allocation to underperforming industrial conglomerate General Electric. Also, the fund’s cash position detracted in a rising market.

Notes to Financial Statements

For the period ended June 30, 2017

1. Organization.

Fidelity Advisor Series Growth & Income Fund (the Fund) is a fund of Fidelity Hastings Street Trust (the Trust) and is authorized to issue an unlimited number of shares. Shares of the Fund are only available for purchase by mutual funds for which Fidelity Management & Research Company (FMR) or an affiliate serves as an investment manager. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.

2. Investments in Fidelity Central Funds.

3. Significant Accounting Policies.

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

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

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

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

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. Corporate bonds are valued by pricing vendors who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Exchange-traded options are valued using the last sale price or, in the absence of a sale, the last offering price and are categorized as Level 1 in the hierarchy. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

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

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

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, future transactions, market discount, partnerships, passive foreign investment companies (PFIC), certain conversion ratio adjustments, equity-debt classifications and losses deferred due to wash sales and excise tax regulations.

The federal tax cost of investment securities and unrealized appreciation (depreciation) as of period end were as follows:

Gross unrealized appreciation	$284,910,329
Gross unrealized depreciation	(57,752,432)
Net unrealized appreciation (depreciation) on securities	$227,157,897
Tax Cost	$1,430,685,789

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

Undistributed ordinary income	$8,687,445
Undistributed long-term capital gain	$46,105,644
Net unrealized appreciation (depreciation) on securities and other investments	$223,176,929

The tax character of distributions paid was as follows:

	June 30, 2017	June 30, 2016
Ordinary Income	$18,336,750	$ 28,511,863
Long-term Capital Gains	1,301,789	52,957,545
Total	$19,638,539	$ 81,469,408

Consolidated Subsidiary. The Fund invests in certain investments through a wholly-owned subsidiary ("Subsidiary"), which may be subject to federal and state taxes upon disposition.

As of period end, the Fund held an investment of $2,166,048 in this Subsidiary, representing .13% of the Fund's net assets. The financial statements have been consolidated and include accounts of the Fund and the Subsidiary. Accordingly, all inter-company transactions and balances have been eliminated.

Any cash held by the Subsidiary is restricted as to its use and is presented as Restricted cash in the Statement of Assets and Liabilities.

4. Derivative Instruments.

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

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

Equity Risk

The Fund is also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that the Fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to the Fund. Counterparty credit risk related to exchange-traded futures contracts and exchange-traded options may be mitigated by the protection provided by the exchange on which they trade.

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

Primary Risk Exposure / Derivative Type	Net Realized Gain (Loss)	Change in Net Unrealized Appreciation (Depreciation)
Equity Risk
Futures	$(151,055)	$ -
Written Options	1,398,923	(250,233)
Totals	$1,247,868	$(250,233)

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

Options. Options give the purchaser the right, but not the obligation, to buy (call) or sell (put) an underlying security or financial instrument at an agreed exercise or strike price between or on certain dates. Options obligate the seller (writer) to buy (put) or sell (call) an underlying instrument at the exercise or strike price or cash settle an underlying derivative instrument if the holder exercises the option on or before the expiration date.

The Fund used exchange-traded written covered call options to manage its exposure to the market. When the Fund writes a covered call option, the Fund holds the underlying instrument which must be delivered to the holder upon the exercise of the option.

Upon entering into a written options contract, the Fund will receive a premium. Premiums received are reflected as a liability on the Statement of Assets and Liabilities. Options are valued daily and any unrealized appreciation (depreciation) is reflected on the Statement of Assets and Liabilities. When a written option is exercised, the premium is added to the proceeds from the sale of the underlying instrument in determining the gain or loss realized on that investment. When an option is closed the Fund will realize a gain or loss depending on whether the proceeds or amount paid for the closing sale transaction are greater or less than the premium received. When an option expires, gains and losses are realized to the extent of premiums received. The net realized gain (loss) on closed and expired written options and the change in net unrealized appreciation (depreciation) on written options are reflected separately on the Statement of Operations.

Writing call options tends to decrease exposure to the underlying instrument and risk of loss is the change in value in excess of the premium received.

Any open options at period end are presented in the Schedule of Investments under the caption "Written Options".

The following is a summary of the Fund's written options activity:

	Number of Contracts	Amount of Premiums
Outstanding at beginning of period	6,479	$ 561,191
Options Opened	51,436	3,754,090
Options Exercised	(18,966)	(1,431,013)
Options Closed	(14,758)	(1,047,755)

Outstanding at end of period	10,677	$ 836,347

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities and in-kind transactions, aggregated $656,547,845 and $805,603,293, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee. Effective June 1, 2017, under the management contract approved by the Board and shareholders, Fidelity Management & Research (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund does not pay a management fee. In addition, the investment adviser pays all ordinary operating expenses of the Fund, except custody fees, fees and expenses of the independent Trustees, and certain miscellaneous expenses such as proxy and shareholder meeting expenses.

Prior to June 1, 2017, the investment adviser and its affiliates provided the Fund with investment management related services for which the Fund paid a monthly management fee. The management fee was the sum of an individual fund fee rate that was based on an annual rate of .20% of the Fund's average net assets and an annualized group fee rate that averaged .25% during the period. The group fee rate was based upon the average net assets of all the mutual funds advised by the investment adviser, including any mutual funds previously advised by the investment adviser that are currently advised by Fidelity SelectCo, LLC, an affiliate of the investment adviser. The group fee rate decreased as assets under management increased and increased as assets under management decreased.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of the investment adviser, is the Fund's transfer, dividend disbursing and shareholder servicing agent. Effective June 1, 2017, fees for these services are no longer charged to the classes. Prior to June 1, 2017, FIIOC received account fees and asset-based fees that varied according to account size and type of account. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, the transfer agent fees were equivalent to an annual rate of .15% of average net assets.

Borrower or Lender	Average Loan Balance	Weighted Average Interest Rate	Interest Expense
Borrower	$9,010,353	.76%	$3,215

Exchanges In-Kind. During the period, certain affiliated entities (Investing Funds) completed exchanges in-kind with the Fund. The Investing Funds delivered investments and cash valued at $504,085,301 in exchange for 34,036,820 shares of the Fund. The amount of in-kind exchanges is included in share transactions in the accompanying Statement of Changes in Net Assets as well as the Notes to Financial Statements. The Fund recognized no gain or loss for federal income tax purposes.

7. Committed Line of Credit.

The Fund participates with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $3,852 and is reflected in Miscellaneous expenses on the Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Security Lending.

9. Expense Reductions.

In addition, during the period the investment adviser reimbursed and/or waived a portion of operating expenses in the amount of $9,375.

10. Other.

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

These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fidelity Advisor Series Growth & Income Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.

Our procedures included confirmation of securities owned as of June 30, 2017 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.

Shareholder Expense Example

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (January 1, 2017 to June 30, 2017).

Actual Expenses

The first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

	Annualized Expense Ratio-^A	Beginning Account Value January 1, 2017	Ending Account Value June 30, 2017	Expenses Paid During Period-^B January 1, 2017 to June 30, 2017
Actual	.52%	$1,000.00	$1,059.30	$2.66-^C
Hypothetical-^D		$1,000.00	$1,022.22	$2.61-^C

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

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

^C If fees and changes to the Fund's expense contract and/ or expense cap, effective June 1, 2017, had been in effect during the entire period, the restated annualized expense ratio would have been .01% and the expenses paid in the actual and hypothetical examples above would have been $.05 and $.05, respectively.

^D 5% return per year before expenses

Distributions (Unaudited)

The Board of Trustees of Fidelity Advisor Series Growth & Income Fund voted to pay on August 14, 2017, to shareholders of record at the opening of business on August 11, 2017, a distribution of $0.412 per share derived from capital gains realized from sales of portfolio securities.

The fund hereby designates as a capital gain dividend with respect to the taxable year ended June 30, 2017, $47,407,433, or, if subsequently determined to be different, the net capital gain of such year.

A total of 0.03% of the dividends distributed during the fiscal year was derived from interest on U.S. Government securities which is generally exempt from state income tax.

The fund designates 97%, 97%, 100%, and 100% of the dividends distributed in July, August, October, and December, respectively during the fiscal year as qualifying for the dividends–received deduction for corporate shareholders.

The fund designates 100% of each dividend distributed during the fiscal year as amounts which may be taken into account as a dividend for purposes of the maximum rate under section 1(h)(11) of the Internal Revenue Code.

The fund will notify shareholders in January 2018 of amounts for use in preparing 2017 income tax returns.

Management's Discussion of Fund Performance

Comments from Portfolio Manager Jean Park: For the year, the fund’s share classes returned about 14%, trailing the 17.90% return of the benchmark S&P 500^® index. Versus the benchmark, stock picking in health care, financials and materials detracted from performance, as did an overweighting in the weak-performing energy sector. Oil’s price lost considerable ground in the first half of 2017, hurting our position in exploration & production firm Anadarko Petroleum, the fund’s largest relative detractor, as well as Devon Energy and energy-services provider Schlumberger. The latter two stocks were sold from the fund. One detractor in health care was an overweighting in pharmaceutical giant Bristol-Myers Squibb, which was sold from the fund. Conversely, picks and an underweighting in telecommunication services and an overweighting in information technology lifted relative results. At the stock level, avoiding two weak-performing index names bolstered relative performance: Exxon Mobil and Verizon Communications, our two largest relative contributors. A token position in General Electric – which we ultimately sold – also helped. Among stocks we overweighted, software developer Adobe Systems stood out for positive reasons, as did a non-benchmark stake in Vail Resorts.

Note to shareholders: On April 10, 2017, Jean Park became Co-Manager of the fund, joining Lead Manager John Avery until July 1, 2017, when she became sole Portfolio Manager.

Notes to Financial Statements

For the period ended June 30, 2017
(Amounts in thousands except percentages)

1. Organization.

Fidelity Fund (the Fund) is a fund of Fidelity Hastings 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 Fidelity Fund and Class K 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.

2. Investments in Fidelity Central Funds.

3. Significant Accounting Policies.

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

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

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

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

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. U.S. government and government agency obligations are valued by pricing vendors who utilize matrix pricing which considers prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances. 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.

Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy.

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 and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Fund is informed of the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Certain distributions received by the Fund represent a return of capital or capital gain. The Fund determines the components of these distributions subsequent to the ex-dividend date, based upon receipt of tax filings or other correspondence relating to the underlying investment. These distributions are recorded as a reduction of cost of investments and/or as a realized gain. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

Deferred Trustee Compensation. Under a Deferred Compensation Plan (the Plan), independent Trustees may elect to defer receipt of a portion of their annual compensation. Deferred amounts are invested in a cross-section of Fidelity funds, are marked-to-market and remain in the Fund until distributed in accordance with the Plan. The investment of deferred amounts and the offsetting payable to the Trustees are included in the accompanying Statement of Assets and Liabilities.

Book-tax differences are primarily due to futures contracts, foreign currency transactions, passive foreign investment companies (PFIC), market discount, partnerships, deferred trustees compensation and losses deferred due to wash sales.

The federal tax cost of investment securities and unrealized appreciation (depreciation) as of period end were as follows:

Gross unrealized appreciation	$1,084,317
Gross unrealized depreciation	(13,214)
Net unrealized appreciation (depreciation) on securities	$1,071,103
Tax Cost	$3,375,016

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

Undistributed ordinary income	$22,820
Undistributed long-term capital gain	$383,296
Net unrealized appreciation (depreciation) on securities and other investments	$1,068,454

The tax character of distributions paid was as follows:

	June 30, 2017	June 30,2016
Ordinary Income	$45,768	$ 38,221
Long-term Capital Gains	254,005	223,507
Total	$299,773	$ 261,728

4. Derivative Instruments.

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

Equity Risk

Any open futures contracts at period end are presented in the Schedule of Investments under the caption "Futures Contracts". The underlying face amount at value reflects each contract's exposure to the underlying instrument or index at period end and is representative of volume of activity during the period. Securities deposited to meet initial margin requirements are identified in the Schedule of Investments.

During the period the Fund recognized net realized gain (loss) of $9,806 and a change in net unrealized appreciation (depreciation) of $(389) related to its investment in futures contracts. These amounts are included in the Statement of Operations.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $3,560,797 and $4,116,461, respectively.

6. Fees and Other Transactions with Affiliates.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc., (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of Fidelity Fund, except for Class K. FIIOC receives an asset-based fee of Class K'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
Fidelity Fund	$5,681	.15
Class K	289	.05
	$5,970

Borrower or Lender	Average Loan Balance	Weighted Average Interest Rate	Interest Expense
Borrower	$8,829	.71%	$1

7. Committed Line of Credit.

The Fund participates with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $15 and is reflected in Miscellaneous expenses on the Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The Fund or borrower may terminate the loan at any time, and if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Fund may apply collateral received from the borrower against the obligation. The Fund may experience delays and costs in recovering the securities loaned. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. At period end, there were no security loans outstanding. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Total security lending income during the period amounted to $23, including $1 from securities loaned to FCM.

9. Expense Reductions.

In addition, during the period the investment adviser reimbursed and/or waived a portion of fund-level operating expenses in the amount of $37.

10. Distributions to Shareholders.

Distributions to shareholders of each class were as follows:

	Year ended June 30, 2017	Year ended June 30, 2016

Hypothetical-^C		$1,000.00	$1,022.27	$2.56
Class K	.41%
Actual		$1,000.00	$1,092.10	$2.13
Hypothetical-^C		$1,000.00	$1,022.76	$2.06

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

Notes to Financial Statements

For the period ended June 30, 2017
(Amounts in thousands except percentages)

1. Organization.

2. Investments in Fidelity Central Funds.

3. Significant Accounting Policies.

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

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

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

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

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. U.S. government and government agency obligations are valued by pricing vendors who utilize matrix pricing which considers prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances. 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.

Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy.

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 and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Fund is informed of the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Certain distributions received by the Fund represent a return of capital or capital gain. The Fund determines the components of these distributions subsequent to the ex-dividend date, based upon receipt of tax filings or other correspondence relating to the underlying investment. These distributions are recorded as a reduction of cost of investments and/or as a realized gain. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

The federal tax cost of investment securities and unrealized appreciation (depreciation) as of period end were as follows:

Gross unrealized appreciation	$1,084,317
Gross unrealized depreciation	(13,214)
Net unrealized appreciation (depreciation) on securities	$1,071,103
Tax Cost	$3,375,016

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

Undistributed ordinary income	$22,820
Undistributed long-term capital gain	$383,296
Net unrealized appreciation (depreciation) on securities and other investments	$1,068,454

The tax character of distributions paid was as follows:

	June 30, 2017	June 30,2016
Ordinary Income	$45,768	$ 38,221
Long-term Capital Gains	254,005	223,507
Total	$299,773	$ 261,728

4. Derivative Instruments.

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

Equity Risk

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $3,560,797 and $4,116,461, respectively.

6. Fees and Other Transactions with Affiliates.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc., (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of Fidelity Fund, except for Class K. FIIOC receives an asset-based fee of Class K'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
Fidelity Fund	$5,681	.15
Class K	289	.05
	$5,970

Borrower or Lender	Average Loan Balance	Weighted Average Interest Rate	Interest Expense
Borrower	$8,829	.71%	$1

7. Committed Line of Credit.

The Fund participates with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $15 and is reflected in Miscellaneous expenses on the Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The Fund or borrower may terminate the loan at any time, and if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Fund may apply collateral received from the borrower against the obligation. The Fund may experience delays and costs in recovering the securities loaned. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. At period end, there were no security loans outstanding. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Total security lending income during the period amounted to $23, including $1 from securities loaned to FCM.

9. Expense Reductions.

In addition, during the period the investment adviser reimbursed and/or waived a portion of fund-level operating expenses in the amount of $37.

10. Distributions to Shareholders.

Distributions to shareholders of each class were as follows:

	Year ended June 30, 2017	Year ended June 30, 2016

Management's Discussion of Fund Performance

Comments from Portfolio Manager Matthew Fruhan: For the fiscal year, the fund’s share classes (excluding sales charges, if applicable) gained roughly 20 to 21%, outpacing the 18.65% advance of the mega-cap proxy Russell Top 200^® Index, as well as the S&P 500^®. The fund’s strong outperformance of the Russell mega-cap index was due to favorable stock picking and a helpful overweight in the market-leading banking industry within the financials sector. I’ve emphasized banks in the fund for some time, and I’m pleased my patience and willingness to be contrarian here was rewarded this period. In financials, Bank of America, JPMorgan Chase and Citigroup – all among the fund’s largest holdings and top contributors – led the way. Elsewhere, security selection in energy was helpful, although the positive impact was essentially offset by a sizable overweight in the lagging sector. Here, the fund benefited from my decision to largely avoid Exxon Mobil, a large index component whose shares returned about -11%. As the valuation fell, I added a small stake in Exxon Mobil. Conversely, detractors included stock picking in consumer discretionary and health care – especially a poor-performing non-benchmark position in drug maker Teva Pharmaceutical Industries – and an allocation to underperforming industrial conglomerate General Electric. Lastly, the fund’s cash position in a rising market detracted.

Notes to Financial Statements

For the period ended June 30, 2017

1. Organization.

Fidelity Mega Cap Stock Fund (the Fund) is a fund of Fidelity Hastings 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 (formerly Class T), Class C, Mega Cap Stock, 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.

After the close of business on June 24, 2016, all outstanding Class B shares were converted to Class A shares. All prior fiscal period dollar and share amounts for Class B presented in the Notes to Financial Statements are for the period July 1, 2015 through June 24, 2016.

2. Investments in Fidelity Central Funds.

3. Significant Accounting Policies.

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

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

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

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 and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Fund is informed of the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Certain distributions received by the Fund represent a return of capital or capital gain. The Fund determines the components of these distributions subsequent to the ex-dividend date, based upon receipt of tax filings or other correspondence relating to the underlying investment. These distributions are recorded as a reduction of cost of investments and/or as a realized gain. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

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

Book-tax differences are primarily due to losses deferred due to wash sales and excise tax regulations.

The federal tax cost of investment securities and unrealized appreciation (depreciation) as of period end were as follows:

Gross unrealized appreciation	$787,011,249
Gross unrealized depreciation	(31,987,846)
Net unrealized appreciation (depreciation) on securities	$755,023,403
Tax Cost	$1,458,921,434

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

Undistributed ordinary income	$17,579,158
Undistributed long-term capital gain	$241,325,491
Net unrealized appreciation (depreciation) on securities and other investments	$754,022,865

The tax character of distributions paid was as follows:

	June 30, 2017	June 30, 2016
Ordinary Income	$52,216,198	$ 54,079,879
Long-term Capital Gains	17,291,428	85,392,058
Total	$69,507,626	$ 139,471,937

Consolidated Subsidiary. The Fund invests in certain investments through a wholly-owned subsidiary ("Subsidiary"), which may be subject to federal and state taxes upon disposition.

As of period end, the Fund held an investment of $6,259,732 in this Subsidiary, representing .28% of the Fund's net assets. The financial statements have been consolidated and include accounts of the Fund and the Subsidiary. Accordingly, all inter-company transactions and balances have been eliminated.

Any cash held by the Subsidiary is restricted as to its use and is presented as Restricted cash in the Statement of Assets and Liabilities.

4. Derivative Instruments.

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

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

Equity Risk

The Fund is also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that the Fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to the Fund. Counterparty credit risk related to exchange-traded options may be mitigated by the protection provided by the exchange on which they trade.

Writing call options tends to decrease exposure to the underlying instrument and risk of loss is the change in value in excess of the premium received.

Any open options at period end are presented in the Schedule of Investments under the caption "Written Options".

During the period, the Fund recognized net realized gain (loss) of $3,151,745 and a change in net unrealized appreciation (depreciation) of $(1,314,943) related to its investment in written options. This amount is included in the Statement of Operations.

The following is a summary of the Fund's written options activity:

	Number of Contracts	Amount of Premiums
Outstanding at beginning of period	10,200	$772,283
Options Opened	118,890	8,766,463
Options Exercised	(39,337)	(3,259,914)
Options Closed	(41,285)	(2,911,126)
Options Expired	(34,440)	(2,249,459)
Outstanding at end of period	14,028	$1,118,247

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $787,832,349 and $2,486,975,763, respectively.

6. Fees and Other Transactions with Affiliates.

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 Corporation (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%	$166,268	$1,515
Class M	.25%	.25%	139,758	–
Class C	.75%	.25%	332,131	37,424
			$638,157	$38,939

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	$34,724
Class M	4,325
Class C^(a)	2,462
	$41,511

(a) When Class C shares are initially sold, FDC pays commissions from its own resources to financial intermediaries through which the sales are made.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc., (FIIOC), an affiliate of the investment adviser, is the transfer, dividend disbursing and shareholder servicing agent for each class of the 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
Class A	$132,456	.20
Class M	58,664	.21
Class C	67,862	.20
Mega Cap Stock	5,531,834	.20
Class I	282,771	.19
Class Z	45,546	.05
	$6,119,133

Borrower or Lender	Average Loan Balance	Weighted Average Interest Rate	Interest Expense
Borrower	$21,701,185	.62%	$10,019

Other. During the period, the investment adviser reimbursed the Fund for certain losses in the amount of $1,535.

7. Committed Line of Credit.

The Fund participates with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $11,678 and is reflected in Miscellaneous expenses on the Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. The Fund or borrower may terminate the loan at any time, and if the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Fund may apply collateral received from the borrower against the obligation. The Fund may experience delays and costs in recovering the securities loaned. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. At period end, there were no security loans outstanding. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Total security lending income during the period amounted to $53,046. During the period, there were no securities loaned to FCM.

9. Expense Reductions.

Commissions paid to certain brokers with whom the investment adviser, or its affiliates, places trades on behalf of the Fund include an amount in addition to trade execution, which may be rebated back to the Fund to offset certain expenses. This amount totaled $5,728 for the period. In addition, through arrangements with the Fund's custodian credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expense. During the period, these credits reduced the Fund's custody expenses by $203.

In addition, during the period the investment adviser reimbursed and/or waived a portion of fund-level operating expenses in the amount of $28,660.

10. Distributions to Shareholders.

Distributions to shareholders of each class were as follows:

Report of Independent Registered Public Accounting Firm

To the Trustees of Fidelity Hastings Street Trust and Shareholders of Fidelity Mega Cap Stock Fund:

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Fidelity Mega Cap Stock Fund (a fund of Fidelity Hastings Street Trust) as of June 30, 2017, 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 periods indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fidelity Mega Cap Stock Fund’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of June 30, 2017 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.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemption proceeds, and (2) ongoing costs, including 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 the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (January 1, 2017 to June 30, 2017).
