Fund Summary

Fund/Class:
Fidelity® Climate Action Fund/Fidelity® Climate Action Fund

Investment Objective

The fund seeks long-term growth of capital.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy and hold shares of the fund.

Shareholder fees

(fees paid directly from your investment)

None

Annual Operating Expenses

(expenses that you pay each year as a % of the value of your investment)

Management fee (fluctuates based on the fund's performance relative to a securities market index)		%
Distribution and/or Service (12b-1) fees		None
Other expenses^(a)		%
Total annual operating expenses		%
Fee waiver and/or expense reimbursement^(b)		%
Total annual operating expenses after fee waiver and/or expense reimbursement		%

^(a)Based on estimated amounts for the current fiscal year.

^(b)Fidelity Management & Research Company LLC (FMR) has contractually agreed to reimburse the class of shares of the fund to the extent that total operating expenses (excluding interest, certain taxes, fees and expenses of the Independent Trustees, proxy and shareholder meeting expenses, extraordinary expenses, and acquired fund fees and expenses, if any, as well as non-operating expenses such as brokerage commissions and fees and expenses associated with the fund's securities lending program, if applicable), as a percentage of its average net assets, exceed [__]% (the Expense Cap). If at any time during the current fiscal year expenses for the class of shares of the fund fall below the Expense Cap, FMR reserves the right to recoup through the end of the fiscal year any expenses that were reimbursed during the current fiscal year up to, but not in excess of, the Expense Cap. This arrangement will remain in effect through [_____]. FMR may not terminate this arrangement before the expiration date without the approval of the Board of Trustees and may extend it in its discretion after that date.

This example helps compare the cost of investing in the fund with the cost of investing in other funds.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that your shareholder fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

1 year	$
3 years	$

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the fund's performance.

Principal Investment Strategies

Normally investing at least 80% of assets in equity securities of climate aware companies.

Climate aware companies are those that Fidelity Management & Research Company LLC (FMR) believes are working to address climate change or its impacts either indirectly through their corporate strategy, or directly through the technology, services, or products they provide. Such companies include those that (i) have a low carbon transition score of neutral or better as rated by MSCI within the MSCI World Climate Change Index, (ii) have an above average environmental score as rated by MSCI, and/or (iii) have an above average environmental systematic score as rated by FMR (FMR E Score). The neutral rating within the MSCI World Climate Change Index represents companies with limited exposure to low carbon transition carbon risk. The FMR E Score represents the portion of the Adviser’s proprietary ESG rating process that focuses on the current state of a company’s practices using a data-driven framework that includes proprietary and third-party data. A company’s environmental profile may include, but is not limited to, carbon and toxic emissions, water management, waste management, vulnerability to the physical impacts of climate change, and research and investment into products, services, and energies that reduce emissions and/or provide opportunities to achieve a low carbon transition.

Investing in securities of domestic and foreign issuers.

Investing in either "growth" stocks or "value" stocks or both.

Using fundamental analysis of factors such as each issuer's financial condition and industry position, as well as market and economic conditions, to select investments.

Principal Investment Risks

Stock Market Volatility. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.

Foreign Exposure. Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.

Climate Focus Risk. Because the fund focuses its investments in equity securities of climate aware companies, it will be more susceptible to events or factors affecting these companies. The fund is particularly exposed to such developments as changes in global and regional climates, environmental protection regulatory actions, changes in government standards and subsidy levels, changes in taxation and other domestic and international political, regulatory and economic developments.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

"Growth" Investing. "Growth" stocks can perform differently from the market as a whole and other types of stocks and can be more volatile than other types of stocks.

"Value" Investing. "Value" stocks can perform differently from the market as a whole and other types of stocks and can continue to be undervalued by the market for long periods of time.

Management Risk. The Adviser’s application of the fund’s strategy criteria may not achieve its intended results. The fund could underperform in comparison to other funds with a similar benchmark or similar objectives and investment strategies.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You could lose money by investing in the fund.

Performance

Performance history will be available for the fund after the fund has been in operation for one calendar year.

Investment Adviser

FMR (the Adviser) is the fund's manager. Other investment advisers serve as sub-advisers for the fund.

Portfolio Manager(s)

Asher Anolic (portfolio manager) has managed the fund since [_____] 2021.

Principal Investment Strategies

The Adviser normally invests at least 80% of the fund’s assets in equity securities of climate aware companies.

Climate aware companies are those that FMR believes are working to address climate change or its impacts either indirectly through their corporate strategy, or directly through the technology, services, or products they provide. Such companies include those that (i) have a low carbon transition score of neutral or better as rated by MSCI within the MSCI World Climate Change Index, (ii) have an above average environmental score as rated by MSCI, and/or (iii) have an above average environmental systematic score as rated by FMR (FMR E Score).

A company’s environmental profile may include, but is not limited to, carbon and toxic emissions, water management, waste management, vulnerability to the physical impacts of climate change, and research and investment into products, services, and energies that reduce emissions and/or provide opportunities to achieve a low carbon transition.

The Adviser is not constrained by any particular investment style. At any given time, the Adviser may tend to buy "growth" stocks or "value" stocks, or a combination of both types. In buying and selling securities for the fund, the Adviser relies on fundamental analysis, which involves a bottom-up assessment of a company's potential for success in light of factors including its financial condition, earnings outlook, strategy, management, industry position, and economic and market conditions.

The Adviser may invest the fund's assets in securities of foreign issuers in addition to securities of domestic issuers.

Although the Adviser focuses on investing the fund's assets in securities issued by larger-sized companies, the Adviser may also make substantial investments in securities issued by medium and smaller companies.

If the Adviser's strategies do not work as intended, the fund may not achieve its objective.

Description of Principal Security Types

Equity securities represent an ownership interest, or the right to acquire an ownership interest, in an issuer. Different types of equity securities provide different voting and dividend rights and priority in the event of the bankruptcy of the issuer. Equity securities include common stocks, preferred stocks, convertible securities, and warrants.

Principal Investment Risks

Many factors affect the fund's performance. Developments that disrupt global economies and financial markets, such as pandemics and epidemics, may magnify factors that affect a fund’s performance. The fund's share price changes daily based on changes in market conditions and interest rates and in response to other economic, political, or financial developments. The fund's reaction to these developments will be affected by the types of securities in which the fund invests, the financial condition, industry and economic sector, and geographic location of an issuer, and the fund's level of investment in the securities of that issuer. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money by investing in the fund.

The following factors can significantly affect the fund's performance:

Stock Market Volatility. The value of equity securities fluctuates in response to issuer, political, market, and economic developments. Fluctuations, especially in foreign markets, can be dramatic over the short as well as long term, and different parts of the market, including different market sectors, and different types of equity securities can react differently to these developments. For example, stocks of companies in one sector can react differently from those in another, large cap stocks can react differently from small cap stocks, and "growth" stocks can react differently from "value" stocks. Issuer, political, or economic developments can affect a single issuer, issuers within an industry or economic sector or geographic region, or the market as a whole. Changes in the financial condition of a single issuer can impact the market as a whole. Terrorism and related geo-political risks have led, and may in the future lead, to increased short-term market volatility and may have adverse long-term effects on world economies and markets generally.

Foreign Exposure. Foreign securities, foreign currencies, and securities issued by U.S. entities with substantial foreign operations can involve additional risks relating to political, economic, or regulatory conditions in foreign countries. These risks include fluctuations in foreign exchange rates; withholding or other taxes; trading, settlement, custodial, and other operational risks; and the less stringent investor protection and disclosure standards of some foreign markets. All of these factors can make foreign investments, especially those in emerging markets, more volatile and potentially less liquid than U.S. investments. In addition, foreign markets can perform differently from the U.S. market.

Global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers or providers in, or foreign exchange rates with, a different country or region.

Climate Focus Risk. Because the fund focuses its investments in equity securities of climate aware companies, it will be more susceptible to events or factors affecting these companies. The fund is particularly exposed to such developments as changes in global and regional climates, environmental protection regulatory actions, changes in government standards and subsidy levels, changes in taxation and other domestic and international political, regulatory, and economic developments. In addition, scientific developments, such as breakthroughs in the remediation of global warming, and changes in governmental policies relating to the effects of pollution may affect investments in pollution control, which could in turn affect these companies. Such companies also may be significantly affected by technological changes in industries focusing on energy, pollution control and mitigation of global warming. Because society’s focus on the climate is relatively new, the emphasis and direction of governmental policies is subject to significant change, and rapid technological change could render even new approaches and products obsolete. Some companies involved in climate aware-related industries have more limited operating histories and smaller market capitalizations on average than companies in other sectors. As a result of these and other factors, the market prices of securities of companies involved in climate aware-related industries tend to be considerably more volatile than those of companies in more established sectors and industries.

Issuer-Specific Changes. Changes in the financial condition of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's value. The value of securities of smaller, less well-known issuers can be more volatile than that of larger issuers.

"Growth" Investing. "Growth" stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. "Growth" stocks tend to be more expensive relative to their earnings or assets compared to other types of stocks. As a result, "growth" stocks tend to be sensitive to changes in their earnings and more volatile than other types of stocks.

"Value" Investing. "Value" stocks can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. "Value" stocks tend to be inexpensive relative to their earnings or assets compared to other types of stocks. However, "value" stocks can continue to be inexpensive for long periods of time and may not ever realize their full value.

Management Risk. The Adviser’s application of the fund’s strategy criteria may not achieve its intended results. The fund could underperform in comparison to other funds with a similar benchmark or similar objectives and investment strategies.

In response to market, economic, political, or other conditions, a fund may temporarily use a different investment strategy for defensive purposes. If the fund does so, different factors could affect its performance and the fund may not achieve its investment objective.

Other Investment Strategies

In addition to the principal investment strategies discussed above, the Adviser may lend the fund's securities to broker-dealers or other institutions to earn income for the fund.

The Adviser may also use various techniques, such as buying and selling futures contracts and exchange traded funds, to increase or decrease the fund's exposure to changing security prices or other factors that affect security values.

Shareholder Notice

The following is subject to change only upon 60 days' prior notice to shareholders:

Fidelity^® Climate Action Fund normally invests at least 80% of the fund’s assets in equity securities of climate aware companies.

Valuing Shares

The fund is open for business each day the NYSE is open.

The NAV is the value of a single share. Fidelity normally calculates NAV as of the close of business of the NYSE, normally 4:00 p.m. Eastern time. The fund's assets normally are valued as of this time for the purpose of computing NAV. Fidelity calculates NAV separately for each class of shares of a multiple class fund.

NAV is not calculated and the fund will not process purchase and redemption requests submitted on days when the fund is not open for business. The time at which shares are priced and until which purchase and redemption orders are accepted may be changed as permitted by the Securities and Exchange Commission (SEC).

To the extent that the fund's assets are traded in other markets on days when the fund is not open for business, the value of the fund's assets may be affected on those days. In addition, trading in some of the fund's assets may not occur on days when the fund is open for business.

NAV is calculated using the values of other open-end funds, if any, in which the fund invests (referred to as underlying funds). Shares of underlying funds are valued at their respective NAVs. Other assets are valued primarily on the basis of market quotations, official closing prices, or information furnished by a pricing service. Certain short-term securities are valued on the basis of amortized cost. If market quotations, official closing prices, or information furnished by a pricing service are not readily available or, in the Adviser's opinion, are deemed unreliable for a security, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. For example, if, in the Adviser's opinion, a security's value has been materially affected by events occurring before a fund's pricing time but after the close of the exchange or market on which the security is principally traded, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. Fair value pricing will be used for high yield debt securities when available pricing information is determined to be stale or for other reasons not to accurately reflect fair value.

Arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before a fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Securities trading in overseas markets present time zone arbitrage opportunities when events affecting portfolio security values occur after the close of the overseas markets but prior to the close of the U.S. market. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of NAV by short-term traders.

Policies regarding excessive trading may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.

Fair value pricing is based on subjective judgments and it is possible that the fair value of a security may differ materially from the value that would be realized if the security were sold.

Shareholder Information

Additional Information about the Purchase and Sale of Shares

As used in this prospectus, the term "shares" generally refers to the shares offered through this prospectus.

General Information

Information on Fidelity

Fidelity Investments was established in 1946 to manage one of America's first mutual funds. Today, Fidelity is one of the world's largest providers of financial services.

In addition to its mutual fund business, the company operates one of America's leading brokerage firms, Fidelity Brokerage Services LLC. Fidelity is also a leader in providing tax-advantaged retirement plans for individuals investing on their own or through their employer.

Ways to Invest

Subject to the purchase and sale requirements stated in this prospectus, you may buy or sell shares through a Fidelity^® brokerage account or a Fidelity^® mutual fund account. If you buy or sell shares (other than by exchange) through a Fidelity^® brokerage account, your transactions generally involve your Fidelity^® brokerage core (a settlement vehicle included as part of your Fidelity^® brokerage account).

If you do not currently have a Fidelity^® brokerage account or a Fidelity^® mutual fund account and would like to invest in a fund, you may need to complete an application. For more information about a Fidelity^® brokerage account or a Fidelity^® mutual fund account, please visit Fidelity's web site at www.fidelity.com, call 1-800-FIDELITY, or visit a Fidelity Investor Center (call 1-800-544-9797 for the center nearest you).

You may also buy or sell shares through a retirement account (such as an IRA or an account funded through salary deduction) or an investment professional. Retirement specialists are available at 1-800-544-4774 to answer your questions about Fidelity^® retirement products. If you buy or sell shares through a retirement account or an investment professional, the procedures for buying, selling, and exchanging shares and the account features, policies, and fees may differ from those discussed in this prospectus. Fees in addition to those discussed in this prospectus may apply. For example, you may be charged a transaction fee if you buy or sell shares through a non-Fidelity broker or other investment professional.

Information on Placing Orders

You should include the following information with any order:

Your name
Your account number
Type of transaction requested
Name(s) of fund(s) and class(es)
Dollar amount or number of shares

Certain methods of contacting Fidelity may be unavailable or delayed (for example, during periods of unusual market activity). In addition, the level and type of service available may be restricted.

Frequent Purchases and Redemptions

The fund may reject for any reason, or cancel as permitted or required by law, any purchase or exchange, including transactions deemed to represent excessive trading, at any time.

Excessive trading of fund shares can harm shareholders in various ways, including reducing the returns to long-term shareholders by increasing costs to the fund (such as brokerage commissions or spreads paid to dealers who sell money market instruments), disrupting portfolio management strategies, and diluting the value of the shares in cases in which fluctuations in markets are not fully priced into the fund's NAV.

The fund reserves the right at any time to restrict purchases or exchanges or impose conditions that are more restrictive on excessive trading than those stated in this prospectus.

Excessive Trading Policy

The Board of Trustees has adopted policies designed to discourage excessive trading of fund shares. Excessive trading activity in a fund is measured by the number of roundtrip transactions in a shareholder's account and each class of a multiple class fund is treated separately. A roundtrip transaction occurs when a shareholder sells fund shares (including exchanges) within 30 days of the purchase date.

Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity^® funds within any rolling 12-month period will be blocked for at least 85 days from additional purchases or exchange purchases across all Fidelity^® funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block. Repeat offenders may be subject to long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's control at any time. In addition to enforcing these roundtrip limitations, the fund may in its discretion restrict, reject, or cancel any purchases or exchanges that, in the Adviser's opinion, may be disruptive to the management of the fund or otherwise not be in the fund's interests.

Exceptions

The following transactions are exempt from the fund's excessive trading policy described above: (i) systematic withdrawal and/or contribution programs, (ii) mandatory retirement distributions, (iii) transactions initiated by a plan sponsor or sponsors of certain employee benefit plans or other related accounts, (iv) transactions within a qualified advisory program, and (v) transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund of fund(s), or other strategy funds.

A qualified advisory program is one that demonstrates to Fidelity that the program has investment strategies and trading policies designed to protect the interests of long-term investors and meets specific criteria outlined by Fidelity.

A qualified fund of fund(s) is a mutual fund, qualified tuition program, or other strategy fund consisting of qualified plan assets that either applies the fund's excessive trading policies to shareholders at the fund of fund(s) level, or demonstrates that the fund of fund(s) has an investment strategy coupled with policies designed to control frequent trading that are reasonably likely to be effective as determined by the fund's Treasurer.

Fidelity may choose not to monitor transactions below certain dollar value thresholds.

Omnibus Accounts

Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple investors, are a common form of holding shares among retirement plans and financial intermediaries such as brokers, advisers, and third-party administrators. Individual trades in omnibus accounts are often not disclosed to the fund, making it difficult to determine whether a particular shareholder is engaging in excessive trading. Excessive trading in omnibus accounts is likely to go undetected by the fund and may increase costs to the fund and disrupt its portfolio management.

Under policies adopted by the Board of Trustees, intermediaries will be permitted to apply the fund's excessive trading policy (described above), or their own excessive trading policy if approved by the Adviser. In these cases, the fund will typically not request or receive individual account data but will rely on the intermediary to monitor trading activity in good faith in accordance with its or the fund's policies. Reliance on intermediaries increases the risk that excessive trading may go undetected. For other intermediaries, the fund will generally monitor trading activity at the omnibus account level to attempt to identify disruptive trades. The fund may request transaction information, as frequently as daily, from any intermediary at any time, and may apply the fund's policy to transactions that exceed thresholds established by the Board of Trustees. The fund may prohibit purchases of fund shares by an intermediary or by some or all of any intermediary's clients. There is no assurance that the Adviser will request data with sufficient frequency to detect or deter excessive trading in omnibus accounts effectively.

If you purchase or sell fund shares through a financial intermediary, you may wish to contact the intermediary to determine the policies applicable to your account.

Retirement Plans

For employer-sponsored retirement plans, only participant directed exchanges count toward the roundtrip limits. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund.

Other Information about the Excessive Trading Policy

The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency. The fund reserves the right to modify its policies at any time without prior notice.

The fund does not knowingly accommodate frequent purchases and redemptions of fund shares by investors, except to the extent permitted by the policies described above.

As described in "Valuing Shares," the fund also uses fair value pricing to help reduce arbitrage opportunities available to short-term traders. There is no assurance that the fund's excessive trading policy will be effective, or will successfully detect or deter excessive or disruptive trading.

Buying Shares

Eligibility

Shares are generally available only to investors residing in the United States.

There is no minimum balance or purchase minimum for fund shares.

Price to Buy

The price to buy one share is its NAV. Shares are sold without a sales charge.

Shares will be bought at the NAV next calculated after an order is received in proper form.

The fund has authorized certain intermediaries to accept orders to buy shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be bought at the NAV next calculated after the order is received by the authorized intermediary. If applicable, orders by funds of funds for which Fidelity serves as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.

The fund may stop offering shares completely or may offer shares only on a limited basis, for a period of time or permanently.

If your payment is not received and collected, your purchase may be canceled and you could be liable for any losses or fees the fund or Fidelity has incurred.

Certain financial institutions that have entered into sales agreements with FDC may enter confirmed purchase orders on behalf of customers by phone, with payment to follow no later than the time when fund shares are priced on the following business day. If payment is not received by that time, the order will be canceled and the financial institution could be held liable for resulting fees or losses.

Under applicable anti-money laundering rules and other regulations, purchase orders may be suspended, restricted, or canceled and the monies may be withheld.

Selling Shares

The price to sell one share is its NAV.

Shares will be sold at the NAV next calculated after an order is received in proper form. Normally, redemptions will be processed by the next business day, but it may take up to seven days to pay the redemption proceeds if making immediate payment would adversely affect the fund.

The fund has authorized certain intermediaries to accept orders to sell shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be sold at the NAV next calculated after the order is received by the authorized intermediary. If applicable, orders by funds of funds for which Fidelity serves as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.

See "Policies Concerning the Redemption of Fund Shares" below for additional redemption information.

A signature guarantee is designed to protect you and Fidelity from fraud. If you hold your shares in a Fidelity^® mutual fund account and submit your request to Fidelity by mail, Fidelity may require that your request be made in writing and include a signature guarantee in certain circumstances, such as:

When you wish to sell more than $100,000 worth of shares.
When the address on your account (record address) has changed within the last 15 days or you are requesting that a check be mailed to an address different than the record address.
When you are requesting that redemption proceeds be paid to someone other than the account owner.
In certain situations when the redemption proceeds are being transferred to a Fidelity^® mutual fund account with a different registration.

You should be able to obtain a signature guarantee from a bank, broker (including Fidelity^® Investor Centers), dealer, credit union (if authorized under state law), securities exchange or association, clearing agency, or savings association. A notary public cannot provide a signature guarantee.

When you place an order to sell shares, note the following:

Redemption proceeds (other than exchanges) may be delayed until money from prior purchases sufficient to cover your redemption has been received and collected.
Redemptions may be suspended or payment dates postponed when the NYSE is closed (other than weekends or holidays), when trading on the NYSE is restricted, or as permitted by the SEC.

Redemption proceeds may be paid in securities or other property rather than in cash if the Adviser determines it is in the best interests of the fund.

You will not receive interest on amounts represented by uncashed redemption checks.
If you hold your shares in a Fidelity^® mutual fund account and your redemption check remains uncashed for six months, the check may be invested in additional shares at the NAV next calculated on the day of the investment.
Under applicable anti-money laundering rules and other regulations, redemption requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.

Policies Concerning the Redemption of Fund Shares

If your account is held directly with a fund, the length of time that a fund typically expects to pay redemption proceeds depends on the method you have elected to receive such proceeds. A fund typically expects to make payment of redemption proceeds by wire, automated clearing house (ACH) or by issuing a check by the next business day following receipt of a redemption order in proper form. Proceeds from the periodic and automatic sale of shares of a Fidelity^® money market fund that are used to buy shares of another Fidelity^® fund are settled simultaneously.

If your account is held through an intermediary, the length of time that a fund typically expects to pay redemption proceeds depends, in part, on the terms of the agreement in place between the intermediary and a fund. For redemption proceeds that are paid either directly to you from a fund or to your intermediary for transmittal to you, a fund typically expects to make payments by wire, by ACH or by issuing a check on the next business day following receipt of a redemption order in proper form from the intermediary by a fund. Redemption orders that are processed through investment professionals that utilize the National Securities Clearing Corporation will generally settle one to three business days following receipt of a redemption order in proper form.

As noted elsewhere, payment of redemption proceeds may take longer than the time a fund typically expects and may take up to seven days from the date of receipt of the redemption order as permitted by applicable law.

Redemption Methods Available. Generally a fund expects to pay redemption proceeds in cash. To do so, a fund typically expects to satisfy redemption requests either by using available cash (or cash equivalents) or by selling portfolio securities. On a less regular basis, a fund may also satisfy redemption requests by utilizing one or more of the following sources, if permitted: borrowing from another Fidelity^® fund; drawing on an available line or lines of credit from a bank or banks; or using reverse repurchase agreements. These methods may be used during both normal and stressed market conditions.

In addition to paying redemption proceeds in cash, a fund reserves the right to pay part or all of your redemption proceeds in readily marketable securities instead of cash (redemption in-kind). Redemption in-kind proceeds will typically be made by delivering the selected securities to the redeeming shareholder within seven days after the receipt of the redemption order in proper form by a fund.

Exchanging Shares

An exchange involves the redemption of all or a portion of the shares of one fund and the purchase of shares of another fund.

As a shareholder, you have the privilege of exchanging shares for shares of other Fidelity^® funds.

However, you should note the following policies and restrictions governing exchanges:

The exchange limit may be modified for accounts held by certain institutional retirement plans to conform to plan exchange limits and Department of Labor regulations. See your retirement plan materials for further information.
The fund may refuse any exchange purchase for any reason. For example, the fund may refuse exchange purchases by any person or group if, in the Adviser's judgment, the fund would be unable to invest the money effectively in accordance with its investment objective and policies, or would otherwise potentially be adversely affected.
Before any exchange, read the prospectus for the shares you are purchasing, including any purchase and sale requirements.
The shares you are acquiring by exchange must be available for sale in your state.
Exchanges may have tax consequences for you.
If you are exchanging between accounts that are not registered in the same name, address, and taxpayer identification number (TIN), there may be additional requirements.
Under applicable anti-money laundering rules and other regulations, exchange requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.

The fund may terminate or modify exchange privileges in the future.

Other funds may have different exchange restrictions and minimums. Check each fund's prospectus for details.

Accounts may be restricted and/or closed, and the monies withheld, pending verification of this information or as otherwise required under these and other federal regulations. In addition, the fund reserves the right to involuntarily redeem an account in the case of: (i) actual or suspected threatening conduct or actual or suspected fraudulent, illegal or suspicious activity by the account owner or any other individual associated with the account; or (ii) the failure of the account owner to provide information to the fund related to opening the accounts. Your shares will be sold at the NAV, minus any applicable shareholder fees, calculated on the day Fidelity closes your fund position.

Fidelity may charge a fee for certain services, such as providing historical account documents.

Dividends and Capital Gain Distributions

The fund earns dividends, interest, and other income from its investments, and distributes this income (less expenses) to shareholders as dividends. The fund also realizes capital gains from its investments, and distributes these gains (less any losses) to shareholders as capital gain distributions.

The fund normally pays dividends and capital gain distributions in July and December.

Distribution Options

When you open an account, specify on your application how you want to receive your distributions. The following distribution options are available:

1. Reinvestment Option. Any dividends and capital gain distributions will be automatically reinvested in additional shares. If you do not indicate a choice on your application, you will be assigned this option.

2. Income-Earned Option. Any capital gain distributions will be automatically reinvested in additional shares. Any dividends will be paid in cash.

3. Cash Option. Any dividends and capital gain distributions will be paid in cash.

4. Directed Dividends^® Option. Any dividends will be automatically invested in shares of another identically registered Fidelity^® fund. Any capital gain distributions will be automatically invested in shares of another identically registered Fidelity^® fund, automatically reinvested in additional shares of the fund, or paid in cash.

Not all distribution options may be available for every account and certain restrictions may apply. If the distribution option you prefer is not listed on your account application, or if you want to change your current distribution option, visit Fidelity's web site at www.fidelity.com or call 1-800-544-6666 for more information.

If you elect to receive distributions paid in cash by check and the U.S. Postal Service does not deliver your checks, your distribution option may be converted to the Reinvestment Option. You will not receive interest on amounts represented by uncashed distribution checks.

If your dividend check(s) remains uncashed for six months, your check(s) may be invested in additional shares at the NAV next calculated on the day of the investment.

Tax Consequences

As with any investment, your investment in the fund could have tax consequences for you. If you are not investing through a tax-advantaged retirement account, you should consider these tax consequences.

Taxes on Distributions

Distributions you receive from the fund are subject to federal income tax, and may also be subject to state or local taxes.

For federal tax purposes, certain of the fund's distributions, including dividends and distributions of short-term capital gains, are taxable to you as ordinary income, while certain of the fund's distributions, including distributions of long-term capital gains, are taxable to you generally as capital gains. A percentage of certain distributions of dividends may qualify for taxation at long-term capital gains rates (provided certain holding period requirements are met).

If you buy shares when a fund has realized but not yet distributed income or capital gains, you will be "buying a dividend" by paying the full price for the shares and then receiving a portion of the price back in the form of a taxable distribution.

Any taxable distributions you receive from the fund will normally be taxable to you when you receive them, regardless of your distribution option.

Taxes on Transactions

Your redemptions, including exchanges, may result in a capital gain or loss for federal tax purposes. A capital gain or loss on your investment in the fund generally is the difference between the cost of your shares and the price you receive when you sell them.

Portfolio Manager(s)

Asher Anolic is portfolio manager of the fund, which he has managed since [_____] 2021. He also manages other funds. Since joining Fidelity Investments in 2008, Mr. Anolic has worked as a research analyst and portfolio manager.

The statement of additional information (SAI) provides additional information about the compensation of, any other accounts managed by, and any fund shares held by the portfolio manager(s).

From time to time a manager, analyst, or other Fidelity employee may express views regarding a particular company, security, industry, or market sector. The views expressed by any such person are the views of only that individual as of the time expressed 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.

Advisory Fee(s)

The fund pays a management fee to the Adviser. The management fee is calculated and paid to the Adviser every month. The fee is determined by calculating a basic fee and then applying a performance adjustment. The performance adjustment either increases or decreases the management fee, depending on how well the fund has performed relative to the [_____].

Management Fee = Basic Fee +/- Performance Adjustment

The basic fee is calculated by adding a group fee rate to an individual fund fee rate, dividing by twelve, and multiplying the result by the fund's average net assets throughout the month.

The group fee rate is based on the average net assets of a group of mutual funds advised by Fidelity Management & Research Company LLC (FMR). This rate cannot rise above 0.52%, and it drops as total assets under management increase.

For [_____], the group fee rate was [__]%. The individual fund fee rate is [__]%.

The performance adjustment rate is calculated monthly by comparing over the performance period the fund's performance to that of the [_____].

For the purposes of calculating the performance adjustment for the fund, the fund's investment performance will be based on the performance of the class of shares of the fund offered through this prospectus. To the extent that other classes of the fund have higher expenses, this could result in those classes bearing a larger positive performance adjustment and smaller negative performance adjustment than would be the case if each class's own performance were considered.

The performance period will begin on [_____], and will eventually include 36 months. The performance adjustment will not take effect until [_____].

The maximum annualized performance adjustment rate is ±[__]% of the fund's average net assets over the performance period. The performance adjustment rate is divided by twelve and multiplied by the fund's average net assets over the performance period, and the resulting dollar amount is then added to or subtracted from the basic fee.

The Adviser pays FMR UK, FMR H.K., and FMR Japan for providing sub-advisory services.

The basis for the Board of Trustees approving the management contract and sub-advisory agreements for the fund will be included in the fund's [annual/semi-annual] report for the fiscal period ending [_____], when available.

From time to time, the Adviser or its affiliates may agree to reimburse or waive certain fund expenses while retaining the ability to be repaid if expenses fall below the specified limit prior to the end of the fiscal year.

Reimbursement or waiver arrangements can decrease expenses and boost performance.

Fund Distribution

The fund is composed of multiple classes of shares. All classes of the fund have a common investment objective and investment portfolio.

FDC distributes the fund's shares.

Intermediaries may receive from the Adviser, FDC, and/or their affiliates compensation for providing recordkeeping and administrative services, as well as other retirement plan expenses, and compensation for services intended to result in the sale of fund shares. These payments are described in more detail in this section and in the SAI.

Distribution and Service Plan(s)

The fund has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940 (1940 Act) with respect to its shares that recognizes that the Adviser may use its management fee revenues, as well as its past profits or its resources from any other source, to pay FDC for expenses incurred in connection with providing services intended to result in the sale of shares of the fund and/or shareholder support services. The Adviser, directly or through FDC, may pay significant amounts to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for shares of the fund.

If payments made by the Adviser to FDC or to intermediaries under the Distribution and Service Plan were considered to be paid out of a class's assets on an ongoing basis, they might increase the cost of your investment and might cost you more than paying other types of sales charges.

From time to time, FDC may offer special promotional programs to investors who purchase shares of Fidelity^® funds. For example, FDC may offer merchandise, discounts, vouchers, or similar items to investors who purchase shares of certain Fidelity^® funds during certain periods. To determine if you qualify for any such programs, contact Fidelity or visit our web site at www.fidelity.com.

No dealer, sales representative, or any other person has been authorized to give any information or to make any representations, other than those contained in this prospectus and in the related SAI, in connection with the offer contained in this prospectus. If given or made, such other information or representations must not be relied upon as having been authorized by the fund or FDC. This prospectus and the related SAI do not constitute an offer by the fund or by FDC to sell shares of the fund to or to buy shares of the fund from any person to whom it is unlawful to make such offer.

Portfolio Turnover

Principal Investment Strategies

Normally investing at least 80% of assets in equity securities of climate aware companies.

Climate aware companies are those that Fidelity Management & Research Company LLC (FMR) believes are working to address climate change or its impacts either indirectly through their corporate strategy, or directly through the technology, services, or products they provide. Such companies include those that (i) have a low carbon transition score of neutral or better as rated by MSCI within the MSCI World Climate Change Index, (ii) have an above average environmental score as rated by MSCI, and/or (iii) have an above average environmental systematic score as rated by FMR (FMR E Score). The neutral rating within the MSCI World Climate Change Index represents companies with limited exposure to low carbon transition carbon risk. The FMR E Score represents the portion of the Adviser’s proprietary ESG rating process that focuses on the current state of a company’s practices using a data-driven framework that includes proprietary and third-party data. A company’s environmental profile may include, but is not limited to, carbon and toxic emissions, water management, waste management, vulnerability to the physical impacts of climate change, and research and investment into products, services, and energies that reduce emissions and/or provide opportunities to achieve a low carbon transition.

Investing in securities of domestic and foreign issuers.

Investing in either "growth" stocks or "value" stocks or both.

Using fundamental analysis of factors such as each issuer's financial condition and industry position, as well as market and economic conditions, to select investments.

Principal Investment Risks

Stock Market Volatility. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.

Foreign Exposure. Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.

Climate Focus Risk. Because the fund focuses its investments in equity securities of climate aware companies, it will be more susceptible to events or factors affecting these companies. The fund is particularly exposed to such developments as changes in global and regional climates, environmental protection regulatory actions, changes in government standards and subsidy levels, changes in taxation and other domestic and international political, regulatory and economic developments.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

"Growth" Investing. "Growth" stocks can perform differently from the market as a whole and other types of stocks and can be more volatile than other types of stocks.

"Value" Investing. "Value" stocks can perform differently from the market as a whole and other types of stocks and can continue to be undervalued by the market for long periods of time.

Management Risk. The Adviser’s application of the fund’s strategy criteria may not achieve its intended results. The fund could underperform in comparison to other funds with a similar benchmark or similar objectives and investment strategies.

Performance

Performance history will be available for the fund after the fund has been in operation for one calendar year.

Investment Adviser

FMR (the Adviser) is the fund's manager. Other investment advisers serve as sub-advisers for the fund.

Buying Shares

Eligibility

Shares are generally available only to investors residing in the United States.

Each class of the fund has different expenses and features, as described in the applicable prospectus. Investors eligible to purchase one class of shares may also be eligible to purchase other classes of shares of the fund. Your investment professional, as applicable, can help you choose the class of shares that best suits your investment needs. However, plan participants may purchase only the classes of shares that are eligible for sale and available through their plan. Certain classes may have higher expenses than those offered by the plan.

There is no minimum balance or purchase minimum for fund shares.

Price to Buy

The price to buy one share of Class A or Class M is its offering price or its NAV, depending on whether you pay a front-end sales charge.

The price to buy one share of Class C, Class I, or Class Z is its NAV. Class C shares are sold without a front-end sales charge, but may be subject to a CDSC upon redemption. Class I and Class Z shares are sold without a sales charge.

If you pay a front-end sales charge, your price will be Class A's or Class M's offering price. When you buy Class A or Class M shares at the offering price, Fidelity deducts the appropriate sales charge and invests the rest in Class A or Class M shares of the fund. If you qualify for a front-end sales charge waiver, your price will be Class A's or Class M's NAV.

The offering price of Class A or Class M is its NAV plus the sales charge. The offering price is calculated by dividing Class A's or Class M's NAV by the difference between one and the applicable front-end sales charge percentage and rounding to the nearest cent.

The dollar amount of the sales charge for Class A or Class M is the difference between the offering price of the shares purchased and the NAV of those shares. Since the offering price per share is calculated to the nearest cent using standard rounding criteria, the percentage sales charge you actually pay may be higher or lower than the sales charge percentages shown in this prospectus due to rounding. The impact of rounding may vary with the amount of your investment and the size of the class's NAV.

Shares will be bought at the offering price or NAV, as applicable, next calculated after an order is received in proper form.

It is the responsibility of your investment professional to transmit your order to buy shares to Fidelity before the close of business on the day you place your order.

The fund has authorized certain intermediaries to accept orders to buy shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be bought at the offering price or NAV, as applicable, next calculated after the order is received by the authorized intermediary. If applicable, orders by funds of funds for which Fidelity serves as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.

The fund may stop offering shares completely or may offer shares only on a limited basis, for a period of time or permanently.

If your payment is not received and collected, your purchase may be canceled and you could be liable for any losses or fees the fund or Fidelity has incurred.

Shares can be bought or sold through investment professionals using an automated order placement and settlement system that guarantees payment for orders on a specified date.

Certain financial institutions that meet creditworthiness criteria established by FDC may enter confirmed purchase orders on behalf of customers by phone, with payment to follow no later than close of business on the next business day. If payment is not received by that time, the order will be canceled and the financial institution will be liable for any losses.

Under applicable anti-money laundering rules and other regulations, purchase orders may be suspended, restricted, or canceled and the monies may be withheld.

Selling Shares

The price to sell one share of Class A, Class M, or Class C is its NAV, minus any applicable CDSC. The price to sell one share of Class I or Class Z is its NAV.

Shares will be sold at the NAV next calculated after an order is received in proper form, minus any applicable CDSC. Normally, redemptions will be processed by the next business day, but it may take up to seven days to pay the redemption proceeds if making immediate payment would adversely affect the fund.

It is the responsibility of your investment professional to transmit your order to sell shares to Fidelity before the close of business on the day you place your order.

The fund has authorized certain intermediaries to accept orders to sell shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be sold at the NAV next calculated after the order is received by the authorized intermediary, minus any applicable CDSC. If applicable, orders by funds of funds for which Fidelity serves as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.

See "Policies Concerning the Redemption of Fund Shares" below for additional redemption information.

A signature guarantee is designed to protect you and Fidelity from fraud. Fidelity may require that your request be made in writing and include a signature guarantee in certain circumstances, such as:

When you wish to sell more than $100,000 worth of shares.
When the address on your account (record address) has changed within the last 15 days or you are requesting that a check be mailed to an address different than the record address.
When you are requesting that redemption proceeds be paid to someone other than the account owner.
In certain situations when the redemption proceeds are being transferred to a Fidelity^® account with a different registration.

You should be able to obtain a signature guarantee from a bank, broker-dealer, credit union (if authorized under state law), securities exchange or association, clearing agency, or savings association. A notary public cannot provide a signature guarantee.

When you place an order to sell shares, note the following:

Redemption proceeds (other than exchanges) may be delayed until money from prior purchases sufficient to cover your redemption has been received and collected.
Redemptions may be suspended or payment dates postponed when the NYSE is closed (other than weekends or holidays), when trading on the NYSE is restricted, or as permitted by the SEC.

Redemption proceeds may be paid in securities or other property rather than in cash if the Adviser determines it is in the best interests of the fund.

You will not receive interest on amounts represented by uncashed redemption checks.
Under applicable anti-money laundering rules and other regulations, redemption requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.

Class Z:

When your relationship with your managed account provider is terminated, your shares may be sold at the NAV next calculated, in which case the redemption proceeds will remain in your account pending your instruction.

Policies Concerning the Redemption of Fund Shares

Converting Shares

The fund will automatically convert your class of shares of the fund to Class Z shares, if Class Z of the fund is available under your plan.

The fund may convert your Class Z shares to another class of shares of the fund, including classes of shares not offered in this prospectus that are available under your plan, if your plan is no longer eligible to offer Class Z. Information on the other classes of shares of the fund can be found in that class’s prospectus. Investors will be notified in writing before any such conversion to another class.

A conversion will be based on the respective NAVs of the two classes, without the imposition of any fees, on the trade date of the conversion. A conversion between share classes of the same fund is a non-taxable event.

Conversion Feature. Effective June 21, 2021, after a maximum of eight years from the initial date of purchase, Class C shares convert automatically to Class A shares of a fund. Prior to June 21, 2021, after a maximum of 10 years from the initial date of purchase, Class C shares convert automatically to Class A shares of a fund. Conversion to Class A shares will be made at NAV. At the time of conversion, a portion of the Class C shares bought through the reinvestment of dividends or capital gains (Dividend Shares) will also convert to Class A shares. The portion of Dividend Shares that will convert is determined by the ratio of your converting Class C non-Dividend Shares to your total Class C non-Dividend Shares. A fund may convert shares sooner in certain circumstances. A shorter holding period may also apply depending on your intermediary. Please see "Sales Charge Waiver Policies Applied by Certain Intermediaries" in the "Appendix" section of this prospectus. A fund will permit an intermediary to transition Class C shares to Class A shares of the same fund, regardless of holding period, if the intermediary is unable to administer this conversion policy. Such transitions to Class A shares will be made at NAV minus any applicable CDSC.

Exchanging Shares

An exchange involves the redemption of all or a portion of the shares of one fund and the purchase of shares of another fund.

As a Class A shareholder, you have the privilege of exchanging Class A shares for the same class of shares of other Fidelity^® funds that offer Advisor classes of shares at NAV or for Daily Money Class shares of Fidelity^® funds that offer Daily Money Class shares.

As a Class M shareholder, you have the privilege of exchanging Class M shares for the same class of shares of other Fidelity^® funds that offer Advisor classes of shares at NAV or for Advisor M Class shares of Fidelity^® Government Money Market Fund. If you purchased your Class M shares through certain investment professionals that have signed an agreement with FDC, you also have the privilege of exchanging your Class M shares for shares of Fidelity^® Capital Appreciation Fund.

As a Class C shareholder, you have the privilege of exchanging Class C shares for the same class of shares of other Fidelity^® funds that offer Advisor classes of shares or for Advisor C Class shares of Fidelity^{^®}Treasury Money Market Fund.

As a Class I shareholder, you have the privilege of exchanging Class I shares for the same class of shares of other Fidelity^® funds that offer Advisor classes of shares or for shares of Fidelity^® funds.

As a Class Z shareholder, you have the privilege of exchanging Class Z shares for the same class of shares of other Fidelity^® funds that offer Advisor classes of shares or Class Z shares of other Fidelity^® funds available through your employee benefit plan, or if the Fidelity^® fund does not offer Class Z shares, then other classes of the Fidelity^® fund that are available through your plan.

Through your investment professional, you may also move between certain share classes of the same fund. For more information, see the statement of additional information (SAI) or consult your investment professional.

However, you should note the following policies and restrictions governing exchanges:

The exchange limit may be modified for accounts held by certain institutional retirement plans to conform to plan exchange limits and Department of Labor regulations. See your retirement plan materials for further information.
The fund may refuse any exchange purchase for any reason. For example, the fund may refuse exchange purchases by any person or group if, in the Adviser's judgment, the fund would be unable to invest the money effectively in accordance with its investment objective and policies, or would otherwise potentially be adversely affected.
An exchange of shares is not subject to any applicable CDSCs.
Before any exchange, read the prospectus for the shares you are purchasing, including any purchase and sale requirements.
The shares you are acquiring by exchange must be available for sale in your state.
Exchanges may have tax consequences for you if you own shares in a taxable account.
If you are exchanging between accounts that are not registered in the same name, address, and taxpayer identification number (TIN), there may be additional requirements.
Under applicable anti-money laundering rules and other regulations, exchange requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.

The fund may terminate or modify exchange privileges in the future.

Other funds may have different exchange restrictions and minimums. Check each fund's prospectus for details.

Rollover IRAs

Class Z shares generally are not available to IRA rollover accounts. Assets from retirement plans may be invested in other class(es) of shares of the fund through an IRA rollover, including class(es) of shares not offered in this prospectus. Each class of the fund has different expenses and features and may have higher expenses than Class Z shares.

Fund Services

Fund Management

The fund is a mutual fund, an investment that pools shareholders' money and invests it toward a specified goal.

Adviser

FMR. The Adviser is the fund's manager. The address of the Adviser is 245 Summer Street, Boston, Massachusetts 02210.

As the manager, the Adviser has overall responsibility for directing the fund's investments and handling its business affairs.

Sub-Adviser(s)

Portfolio Manager(s)

The SAI provides additional information about the compensation of, any other accounts managed by, and any fund shares held by the portfolio manager(s).

Advisory Fee(s)

Management Fee = Basic Fee +/- Performance Adjustment

The basic fee is calculated by adding a group fee rate to an individual fund fee rate, dividing by twelve, and multiplying the result by the fund's average net assets throughout the month.

For [_____], the group fee rate was [__]%. The individual fund fee rate is [__]%.

The performance adjustment rate is calculated monthly by comparing over the performance period the fund's performance to that of the [_____].

For the purposes of calculating the performance adjustment for the fund, the fund's investment performance will be based on the performance of Fidelity^® Climate Action Fund, a class of shares of the fund that is not offered through this prospectus. To the extent that other classes of the fund have higher expenses, this could result in those classes bearing a larger positive performance adjustment and smaller negative performance adjustment than would be the case if each class's own performance were considered.

The performance period will begin on [_____], and will eventually include 36 months. The performance adjustment will not take effect until [_____].

The Adviser pays FMR UK, FMR H.K., and FMR Japan for providing sub-advisory services.

Reimbursement or waiver arrangements can decrease expenses and boost performance.

Fund Distribution

FDC distributes each class's shares.

Intermediaries may receive from the Adviser, FDC, and/or their affiliates compensation for their services intended to result in the sale of class shares, including compensation for providing recordkeeping and administrative services, as well as other retirement plan expenses for Class Z shares. This compensation may take the form of (as applicable):

Sales charges and concessions (not applicable to Class I and Class Z shares).
Distribution and/or service (12b-1) fees (not applicable to Class I and Class Z shares).
Finder's fees (not applicable to Class C, Class I, and Class Z shares).

You may pay a sales charge when you buy or sell your Class A, Class M, and Class C shares.

FDC collects the sales charge.

As described in detail in this section, you may be entitled to a waiver of your sales charge, or to pay a reduced sales charge, when you buy or sell Class A, Class M, and Class C shares. In the event of changes in sales charges, sales charges, if any, in effect at the time of purchase generally will apply.

The availability of certain sales charge waivers and discounts may depend on whether you purchase your shares directly from a fund or through an intermediary. Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or CDSC (back-end) waivers. Please see “Sales Charge Waiver Policies Applied by Certain Intermediaries” in the “Appendix” section of the prospectus. In all instances, it is the purchaser’s responsibility to notify a fund or the purchaser’s intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers or discounts. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase fund shares directly from a fund or through another intermediary to receive these waivers or discounts.

The front-end sales charge will be reduced for purchases of Class A and Class M shares according to the sales charge schedules below.

Class A or Class M shares purchased by an individual or company through the Combined Purchase, Rights of Accumulation, or Letter of Intent program may receive a reduced front-end sales charge according to the sales charge schedules above. To qualify for a Class A or Class M front-end sales charge reduction under one of these programs, you must notify Fidelity in advance of your purchase.

Combined Purchase, Rights of Accumulation, and Letter of Intent Programs. The following qualify as an "individual" or "company" for the purposes of determining eligibility for the Combined Purchase and Rights of Accumulation program: an individual, spouse, and their children under age 21 purchasing for his/her or their own account; a trustee, administrator, or other fiduciary purchasing for a single trust estate or a single fiduciary account or for a single or parent-subsidiary group of "employee benefit plans" (except SEP and SARSEP plans and plans covering self-employed individuals and their employees (formerly Keogh/H.R. 10 plans)) and 403(b) programs; and tax-exempt organizations (as defined in Section 501(c)(3) of the Internal Revenue Code). The following qualify as an "individual" or "company" for the purposes of determining eligibility for the Letter of Intent program: an individual, spouse, and their children under age 21 purchasing for his/her or their own account; a trustee, administrator, or other fiduciary purchasing for a single trust estate or a single fiduciary account (except SEP and SARSEP plans and plans covering self-employed individuals and their employees (formerly Keogh/H.R. 10 plans)); an IRA or plans covering sole-proprietors (formerly Keogh/H.R. 10 plans); plans investing through the Fidelity Advisor^® 403(b) program; and tax-exempt organizations (as defined in Section 501(c)(3) of the Internal Revenue Code).

Combined Purchase. To receive a Class A or Class M front-end sales charge reduction, if you are a new shareholder, you may combine your purchase of Class A or Class M shares with purchases of: (i) Class A, Class M, and Class C shares of any Fidelity^® fund that offers Advisor classes of shares, (ii) Advisor C Class shares of Fidelity^® Treasury Money Market Fund, and (iii) Class A Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor^® 529 Plan. Purchases may be aggregated across multiple intermediaries on the same day for the purpose of qualifying for the Combined Purchase program.

Rights of Accumulation. To receive a Class A or Class M front-end sales charge reduction, if you are an existing shareholder, you may add to your purchase of Class A or Class M shares the current value of your holdings in: (i) Class A, Class M, and Class C shares of any Fidelity^® fund that offers Advisor classes of shares, (ii) Advisor C Class shares of Fidelity^® Treasury Money Market Fund, (iii) Daily Money Class shares of a fund that offers Daily Money Class shares acquired by exchange from any Fidelity^® fund that offers Advisor classes of shares, (iv) Class O shares of Fidelity Advisor^® Diversified Stock Fund and Fidelity Advisor^® Capital Development Fund, and (v) Class A Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor^® 529 Plan. The current value of your holdings is determined at the NAV at the close of business on the day prior to your purchase of Class A or Class M shares. The current value of your holdings will be added to your purchase of Class A or Class M shares for the purpose of qualifying for the Rights of Accumulation program. Purchases and holdings may be aggregated across multiple intermediaries for the purpose of qualifying for the Rights of Accumulation program.

Letter of Intent. You may receive a Class A or Class M front-end sales charge reduction on your purchases of Class A and Class M shares made during a 13-month period by signing a Letter of Intent (Letter). File your Letter with Fidelity no later than the date of the initial purchase toward completing your Letter. Each Class A or Class M purchase you make toward completing your Letter will be entitled to the reduced front-end sales charge applicable to the total investment indicated in the Letter. Purchases of the following may be aggregated for the purpose of completing your Letter: (i) Class A and Class M shares of any Fidelity^® fund that offers Advisor classes of shares (except those acquired by exchange from Daily Money Class shares of a fund that offers Daily Money Class shares that had been previously exchanged from a Fidelity^® fund that offers Advisor classes of shares), (ii) Class C shares of any Fidelity^® fund that offers Advisor classes of shares, (iii) Advisor C Class shares of Fidelity^® Treasury Money Market Fund, and (iv) Class A Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor^® 529 Plan. Reinvested income and capital gain distributions will not be considered purchases for the purpose of completing your Letter. Purchases may be aggregated across multiple intermediaries for the purpose of qualifying for the Letter of Intent program. Your initial purchase toward completing your Letter must be at least 5% of the total investment specified in your Letter. Fidelity will register Class A or Class M shares equal to 5% of the total investment specified in your Letter in your name and will hold those shares in escrow. You will earn income, dividends and capital gain distributions on escrowed Class A and Class M shares. The escrow will be released when you complete your Letter. You are not obligated to complete your Letter. If you do not complete your Letter, you must pay the increased front-end sales charges due in accordance with the sales charge schedule in effect when your shares were originally bought. Fidelity may redeem sufficient escrowed Class A or Class M shares to pay any applicable front-end sales charges. If you purchase more than the amount specified in your Letter and qualify for additional Class A or Class M front-end sales charge reductions, the front-end sales charge will be adjusted to reflect your total purchase at the end of 13 months and the surplus amount will be applied to your purchase of additional Class A or Class M shares at the then-current offering price applicable to the total investment.

Detailed information about these programs also is available on institutional.fidelity.com. In order to obtain the benefit of a front-end sales charge reduction for which you may be eligible, you may need to inform your investment professional of other accounts you, your spouse, or your children maintain with your investment professional or other investment professionals from the same intermediary.

Class C shares may, upon redemption less than one year after purchase, for any reason, be assessed a CDSC of 1.00%. The actual CDSC you pay may be higher or lower than that calculated using this percentage due to rounding. The impact of rounding may vary with the amount of your investment and the size of the class's NAV.

Investment professionals will receive as compensation from FDC, at the time of the sale, a concession equal to 1.00% of your purchase of Class C shares. A concession will not apply to Class C shares acquired through reinvestment of dividends or capital gain distributions.

The CDSC for Class A, Class M, and Class C shares will be calculated based on the lesser of the cost of each class's shares, as applicable, at the initial date of purchase or the value of those shares, as applicable, at redemption, not including any reinvested dividends or capital gains. Class A, Class M, and Class C shares acquired through reinvestment of dividends or capital gain distributions will not be subject to a CDSC. In determining the applicability and rate of any CDSC at redemption, shares representing reinvested dividends and capital gains will be redeemed first, followed by those shares that have been held for the longest period of time.

A front-end sales charge will not apply to the following Class A or Class M shares:

Finder's Fees. Finder's fees may be paid to investment professionals who sell Class A and Class M shares in purchase amounts of $1 million or more. For Class A share purchases, investment professionals may be compensated at the time of purchase with a finder's fee at the rate of 1.00% of the purchase amount for purchases of $1 million up to $4 million, 0.50% of the purchase amount for purchases of $4 million up to $25 million, and 0.25% of the purchase amount for purchases of $25 million or more. For Class M share purchases, investment professionals may be compensated at the time of purchase with a finder's fee at the rate of 0.25% of the purchase amount.

Investment professionals may be eligible for a finder's fee on the following purchases of Class A and Class M shares made through broker-dealers and banks: a trade that brings the value of the accumulated account(s) of an investor, including a 403(b) program or an employee benefit plan (except a SEP or SARSEP plan or a plan covering self-employed individuals and their employees (formerly a Keogh/H.R. 10 plan)), over $1 million; a trade for an investor with an accumulated account value of $1 million or more; and an incremental trade toward an investor's $1 million Letter. Accumulated account value for purposes of finder's fees eligibility is determined the same as it is for Rights of Accumulation. Daily Money Class shares of a fund that offers Daily Money Class shares are not counted for this purpose unless acquired by exchange from any Fidelity^® fund that offers Advisor classes of shares. For information, see "Combined Purchase, Rights of Accumulation, and Letter of Intent Programs" above.

Finder's fees are not paid in connection with purchases of Class A or Class M shares by insurance company separate accounts or managed account programs that charge an asset-based fee, or purchases of Class A or Class M shares made with the proceeds from the redemption of shares of any Fidelity^® fund or any retirement plan recordkept at Fidelity.

Investment professionals should contact Fidelity in advance to determine if they qualify to receive a finder's fee. Finder's fees will be paid in connection with shares recordkept in a Fidelity Advisor^® 401(k) Retirement Plan only at the time of the initial conversion of assets. Investment professionals should contact Fidelity for more information.

Reinstatement Privilege. If you have sold all or part of your Class A, Class M, or Class C shares of the fund, you may reinvest an amount equal to all or a portion of the redemption proceeds in the same class of the fund or another Fidelity^® fund that offers Advisor classes of shares, at the NAV next determined after receipt in proper form of your investment order, provided that such reinvestment is made within 90 days of redemption. Under these circumstances, the dollar amount of the CDSC you paid, if any, on shares will be reimbursed to you by reinvesting that amount in Class A, Class M, or Class C shares, as applicable.

You must reinstate your shares into an account with the same registration. This privilege may be exercised only once by a shareholder with respect to the fund and certain restrictions may apply. For purposes of the CDSC schedule, the holding period will continue as if the Class A, Class M, or Class C shares had not been redeemed. To qualify for the reinstatement privilege, you must notify Fidelity in writing in advance of your reinvestment.

Distribution and Service Plan(s)

Class A has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. Under the plan, Class A is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class A shares. Class A may pay this 12b-1 (distribution) fee at an annual rate of [__]% of its average net assets, or such lesser amount as the Trustees may determine from time to time. Currently, the Trustees have not approved such payments. The Trustees may approve 12b-1 (distribution) fee payments at an annual rate of up to [__]% of Class A's average net assets when the Trustees believe that it is in the best interests of Class A shareholders to do so.

In addition, pursuant to the Class A plan, Class A pays FDC a monthly 12b-1 (service) fee at an annual rate of [__]% of Class A's average net assets throughout the month for providing shareholder support services.

Except as provided below, FDC may reallow up to the full amount of this 12b-1 (service) fee to intermediaries, including its affiliates, for providing shareholder support services. For purchases of Class A shares on which a finder's fee was paid to intermediaries, after the first year of investment, FDC may reallow up to the full amount of the 12b-1 (service) fee paid by such shares to intermediaries, including its affiliates, for providing shareholder support services.

Class M has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. Under the plan, Class M is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class M shares. Class M may pay this 12b-1 (distribution) fee at an annual rate of [__]% of its average net assets, or such lesser amount as the Trustees may determine from time to time. Class M currently pays FDC a monthly 12b-1 (distribution) fee at an annual rate of [__]% of its average net assets throughout the month. Class M's 12b-1 (distribution) fee rate may be increased only when the Trustees believe that it is in the best interests of Class M shareholders to do so.

FDC may reallow up to the full amount of this 12b-1 (distribution) fee to intermediaries, including its affiliates, for providing services intended to result in the sale of Class M shares.

In addition, pursuant to the Class M plan, Class M pays FDC a monthly 12b-1 (service) fee at an annual rate of [__]% of Class M's average net assets throughout the month for providing shareholder support services.

FDC may reallow up to the full amount of this 12b-1 (service) fee to intermediaries, including its affiliates, for providing shareholder support services.

Class C has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. Under the plan, Class C is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class C shares. Class C currently pays FDC a monthly 12b-1 (distribution) fee at an annual rate of [__]% of its average net assets throughout the month.

In addition, pursuant to the Class C plan, Class C pays FDC a monthly 12b-1 (service) fee at an annual rate of [___]% of Class C's average net assets throughout the month for providing shareholder support services.

Normally, after the first year of investment, FDC may reallow up to the full amount of the 12b-1 (distribution) fees to intermediaries, including its affiliates, for providing services intended to result in the sale of Class C shares and may reallow up to the full amount of the 12b-1 (service) fee to intermediaries, including its affiliates, for providing shareholder support services.

For purchases of Class C shares made through reinvestment of dividends or capital gain distributions, during the first year of investment and thereafter, FDC may reallow up to the full amount of this 12b-1 (distribution) fee paid by such shares to intermediaries, including its affiliates, for providing services intended to result in the sale of Class C shares and may reallow up to the full amount of this 12b-1 (service) fee paid by such shares to intermediaries, including its affiliates, for providing shareholder support services.

Any fees paid out of Class A’s, Class M’s, and Class C’s assets on an ongoing basis pursuant to a Distribution and Service Plan will increase the cost of your investment and may cost you more than paying other types of sales charges.

In addition to the above payments, each Class A, Class M, and Class C plan specifically recognizes that the Adviser may make payments from its management fee revenue, past profits, or other resources to FDC for expenses incurred in connection with providing services intended to result in the sale of Class A, Class M, and Class C shares and/or shareholder support services. The Adviser, directly or through FDC or one or more affiliates, may pay significant amounts to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for Class A, Class M, and Class C.

Each of Class I and Class Z has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act that recognizes that the Adviser may use its management fee revenues, as well as its past profits or its resources from any other source, to pay FDC for expenses incurred in connection with providing services intended to result in the sale of Class I and Class Z shares and/or shareholder support services. The Adviser, directly or through FDC, may pay significant amounts to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for Class I and Class Z.

If payments made by the Adviser to FDC or to intermediaries under Class I’s and Class Z’s Distribution and Service Plan were considered to be paid out of Class I’s and Class Z’s assets on an ongoing basis, they might increase the cost of your investment and might cost you more than paying other types of sales charges.

Shareholders purchasing fund shares through an Ameriprise Financial brokerage account are eligible for the following front-end sales charge waivers and discounts, which may differ from those disclosed elsewhere in this prospectus or SAI.

Class A Shares Front-End Sales Charge Waivers Available at Ameriprise Financial:

• Employer-sponsored retirement plans (e.g., 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit sharing and money purchase pension plans and defined benefit plans). For purposes of this provision, employer-sponsored retirement plans do not include SEP IRAs, Simple IRAs or SAR-SEPs.

• Shares purchased through reinvestment of capital gains distributions and dividend reinvestment when purchasing shares of the same fund (but not any other fund within the same fund family).

• Shares exchanged from Class C shares of the same fund in the month of or following the 7-year anniversary of the purchase date. To the extent that this prospectus elsewhere provides for a waiver with respect to exchanges of Class C shares or conversion of Class C shares following a shorter holding period, that waiver will apply.

• Employees and registered representatives of Ameriprise Financial or its affiliates and their immediate family members.

• Shares purchased by or through qualified accounts (including IRAs, Coverdell Education Savings Accounts, 401(k)s, 403(b) TSCAs subject to ERISA and defined benefit plans) that are held by a covered family member, defined as an Ameriprise financial advisor and/or the advisor’s spouse, advisor’s lineal ascendant (mother, father, grandmother, grandfather, great grandmother, great grandfather), advisor’s lineal descendant (son, step-son, daughter, step-daughter, grandson, granddaughter, great grandson, great granddaughter) or any spouse of a covered family member who is a lineal descendant.

• Shares purchased from the proceeds of redemptions within the same fund family, provided (1) the repurchase occurs within 90 days following the redemption, (2) the redemption and purchase occur in the same account, and (3) redeemed shares were subject to a front-end or deferred sales load (i.e. Rights of Reinstatement).

Edward D. Jones & Co., L.P. ("Edward Jones")

Policies Regarding Transactions Through Edward Jones

The following information has been provided by Edward Jones:

Effective on or after February 1, 2021, the following information supersedes prior information with respect to transactions and positions held in fund shares through an Edward Jones system. Clients of Edward Jones (also referred to as "shareholders") purchasing fund shares on the Edward Jones commission and fee-based platforms are eligible only for the following sales charge discounts (also referred to as "breakpoints") and waivers, which can differ from discounts and waivers described elsewhere in the mutual fund prospectus or statement of additional information ("SAI") or through another broker-dealer. In all instances, it is the shareholder's responsibility to inform Edward Jones at the time of purchase of any relationship, holdings of the fund family, or other facts qualifying the purchaser for discounts or waivers. Edward Jones can ask for documentation of such circumstance. Shareholders should contact Edward Jones if they have questions regarding their eligibility for these discounts and waivers.

Breakpoints

• Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds as described in the prospectus.

Rights of Accumulation ("ROA"):

• The applicable sales charge on a purchase of Class A shares is determined by taking into account all share classes (except certain money market funds and any assets held in group retirement plans) of the mutual fund family held by the shareholder or in an account grouped by Edward Jones with other accounts for the purpose of providing certain pricing considerations ("pricing groups"). If grouping assets as a shareholder, this includes all share classes held on the Edward Jones platform and/or held on another platform. The inclusion of eligible fund family assets in the ROA calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Money market funds are included only if such shares were sold with a sales charge at the time of purchase or acquired in exchange for shares purchased with a sales charge.

• The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping as opposed to including all share classes at a shareholder or pricing group level.

• ROA is determined by calculating the higher of cost minus redemptions or market value (current shares x NAV).

Letter of Intent ("LOI"):

• Through a LOI, shareholders can receive the sales charge and breakpoint discounts for purchases shareholders intend to make over a 13-month period from the date Edward Jones receives the LOI. The LOI is determined by calculating the higher of cost or market value of qualifying holdings at LOI initiation in combination with the value that the shareholder intends to buy over a 13-month period to calculate the front-end sales charge and any breakpoint discounts. Each purchase the shareholder makes during that 13-month period will receive the sales charge and breakpoint discount that applies to the total amount. The inclusion of eligible fund family assets in the LOI calculation is dependent on the shareholder notifying Edward Jones of such assets at the time of calculation. Purchases made before the LOI is received by Edward Jones are not adjusted under the LOI and will not reduce the sales charge previously paid. Sales charges will be adjusted if LOI is not met.

If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected to establish or change ROA for the IRA accounts associated with the plan to a plan-level grouping, LOIs will also be at the plan-level and may only be established by the employer.

Sales Charge Waivers:

Sales charges are waived for the following shareholders and in the following situations:

• Associates of Edward Jones and its affiliates and their family members who are in the same pricing group (as determined by Edward Jones under its policies and procedures) as the associate. This waiver will continue for the remainder of the associate's life if the associate retires from Edward Jones in good-standing and remains in good standing pursuant to Edward Jones' policies and procedures.

• Shares purchased in an Edward Jones fee-based program.

• Shares purchased through reinvestment of capital gains distributions and dividend reinvestment.

• Shares purchased from the proceeds of redeemed shares of the same fund family so long as the following conditions are met: 1) the proceeds are from the sale of shares within 60 days of the purchase, and 2) the sale and purchase are made in the same share class and the same account or the purchase is made in an individual retirement account with proceeds from liquidations in a non-retirement account.

• Shares exchanged into Class A shares from another share class so long as the exchange is into the same fund and was initiated at the discretion of Edward Jones. Edward Jones is responsible for any remaining CDSC due to the fund company, if applicable. Any future purchases are subject to the applicable sales charge as disclosed in the prospectus.

• Exchanges from Class C shares to Class A shares of the same fund, generally, in the 84th month following the anniversary of the purchase date or earlier at the discretion of Edward Jones.

CDSC Waivers:

If the shareholder purchases shares that are subject to a CDSC and those shares are redeemed before the CDSC is expired, the shareholder is responsible to pay the CDSC except in the following conditions:

• The death or disability of the shareholder.

• Systematic withdrawals with up to 10% per year of the account value.

• Return of excess contributions from an Individual Retirement Account (IRA).

• Shares sold as part of a required minimum distribution for IRA and retirement accounts if the redemption is taken in or after the year the shareholder reaches qualified age based on applicable IRS regulations.

• Shares sold to pay Edward Jones fees or costs in such cases where the transaction is initiated by Edward Jones.

• Shares exchanged in an Edward Jones fee-based program.

• Shares acquired through NAV reinstatement.

Other Important Information Regarding Transactions Through Edward Jones

Minimum Purchase Amounts:

• Initial purchase minimum: $250

• Subsequent purchase minimum: none

Principal Investment Strategies

Normally investing primarily in equity securities.

Normally investing at least 80% assets in equity securities of U.S. companies that Fidelity Management & Research Company LLC (FMR) believes have proven or improving sustainability practices based on an evaluation of such companies' individual environmental, social, and governance (ESG) profile.

Using FMR’s proprietary ESG ratings process to evaluate the current state of a company’s sustainability practices using a data-driven framework that includes both proprietary and third-party data, and also provide a qualitative forward looking assessment of a company’s sustainability outlook provided by FMR’s fundamental research analysts and ESG team.

FMR’s ESG ratings of companies are derived from multiple factors, including a company’s environmental profile, which may include, but is not limited to, carbon and toxic emissions, water management, waste management, vulnerability to the physical impacts of climate change, and research and investment into products, services, and energies that reduce emissions and/or provide opportunities to achieve a low carbon transition. An assessment of a firm’s social profile includes, but is not limited to, its approach to diversity and inclusion, human capital management, data privacy, product safety and human rights. With respect to governance, the independence and diversity of a company’s board, its compensation practices and board oversight of critical ESG issues are considered as part of the assessment. These factors are weighted based on how material FMR believes each factor is to a company’s financial outlook, and not all factors may be applicable to all companies.

Investing in companies that FMR believes deliver tangible environmental or social impact through core business operations. An assessment of the impact characteristics of a company may involve corporate engagement and an analysis of company alignment with the United Nations Sustainable Development Goals using qualitative analysis as well as proprietary or third-party data. For example, companies that provide access to clean water, education, or clean energy through their core business may be considered to deliver tangible impact.

Investing in securities of domestic and foreign issuers.

In addition to the ESG ratings process, using fundamental analysis of factors such as each issuer's financial condition and industry position, as well as market and economic conditions, to select investments.

Principal Investment Risks

Stock Market Volatility. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.

Sustainability Risk. The fund’s adherence to its ESG ratings process may affect the fund’s exposure to certain companies, sectors, regions, and countries and may affect the fund’s performance depending on whether such investments are in or out of favor. Adhering to the ESG ratings process may also affect the fund’s performance relative to similar funds that do not adhere to such criteria or apply such analysis. The criteria related to the fund’s ESG ratings process may result in the fund forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so, or selling securities for ESG reasons when it might be otherwise disadvantageous for it to do so. There are significant differences in interpretations of what it means for a company to have positive ESG factors. While the Adviser believes its definitions are reasonable, the portfolio decisions it makes may differ with other investors’ or advisers’ views.

Foreign Exposure. Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Small- and Mid-Cap Investing. The value of securities of small to medium size, less well-known issuers can perform differently from the market as a whole and other types of stocks and can be more volatile than that of larger issuers.

Management Risk. The Adviser’s application of the fund’s strategy criteria may not achieve its intended results. The fund could underperform in comparison to other funds with a similar benchmark or similar objectives and investment strategies.

Performance

Performance history will be available for the fund after the fund has been in operation for one calendar year.

Investment Details

Investment Objective

Fidelity^® Sustainability U.S. Equity Fund seeks long-term growth of capital.

Principal Investment Strategies

The Adviser normally invests the fund’s assets primarily in equity securities.

The Adviser normally invests at least 80% of the fund’s assets in equity securities of U.S. companies that the Adviser believes have proven or improving sustainability practices, based on an evaluation of such companies’ individual ESG profile. The Adviser’s proprietary ESG ratings process is designed to evaluate a company’s current and future ESG positioning relative to its peers. The process has two components. One component evaluates the current state of a company’s sustainability practices using a data-driven framework that includes proprietary and third-party data. Another component involves a qualitative forward-looking assessment of a company’s sustainability outlook provided by the Adviser’s fundamental research analysts and ESG team. This qualitative assessment is based on criteria including, but not limited to, the company’s public sustainability disclosure, the company’s systems and policies regarding sustainability, and company engagement on sustainability issues and opportunities.

The Adviser’s ESG ratings of companies are derived from multiple factors, including a company’s environmental profile, which may include, but is not limited to, carbon and toxic emissions, water management, waste management, vulnerability to the physical impacts of climate change, and research and investment into products, services, and energies that reduce emissions and/or provide opportunities to achieve a low carbon transition. An assessment of a firm’s social profile includes, but is not limited to, its approach to diversity and inclusion, human capital management, data privacy, product safety and human rights. With respect to governance, the independence and diversity of a company’s board, its compensation practices and board oversight of critical ESG issues are considered as part of the assessment. These factors are weighted based on how material the Adviser believes each factor is to a company’s financial outlook, and not all factors may be applicable to all companies. Based on this process, the Adviser will assign ratings for a company’s overall ESG performance.

The fund may also invest in companies that the Adviser believes deliver tangible environmental or social impact through core business operations. An assessment of the impact characteristics of a company may involve corporate engagement and an analysis of company alignment with the United Nations Sustainable Development Goals using qualitative analysis as well as proprietary or third-party data. For example, companies that provide access to clean water, education, or clean energy through their core business may be considered to deliver tangible impact.

The fund is not limited to investing in securities of a specific market capitalization and may hold securities of large, medium and/or small capitalization companies.

The Adviser may invest the fund’s assets in securities of foreign issuers in addition to securities of domestic issuers.

In buying and selling securities for the fund, in addition to the ESG ratings process, the Adviser also relies on fundamental analysis, which involves a bottom-up assessment of a company’s potential for success in light of factors including its financial condition, earnings outlook, strategy, management, industry position, and economic and market conditions.

If the Adviser’s strategies do not work as intended, the fund may not achieve its objective.

Description of Principal Security Types

Principal Investment Risks

The following factors can significantly affect the fund's performance:

Sustainability Risk. A fund’s adherence to its ESG ratings process may affect the fund’s exposure to certain companies, sectors, regions, and countries and may affect the fund’s performance depending on whether such investments are in or out of favor. Adhering to the ESG ratings process may also affect a fund’s performance relative to similar funds that do not adhere to such criteria or apply such analysis. The criteria related to a fund’s ESG ratings process may result in the fund forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so, or selling securities for ESG reasons when it might be otherwise disadvantageous for it to do so. There are significant differences in interpretations of what it means for a company to have positive ESG factors. While the Adviser believes its definitions are reasonable, the portfolio decisions it makes may differ with other investors’ or advisers’ views. Socially responsible norms differ by country and region, and a company’s ESG factors or the Adviser’s assessment of such may change over time. A fund may invest in companies that do not reflect the beliefs and values of any particular investor. When conducting the ESG ratings process of an issuer, the Adviser may rely on third-party data that it believes to be reliable, but it does not guarantee the accuracy of such third-party data. Certain investments may be dependent on U.S. and foreign government policies, including tax incentives and subsidies, which may change without notice. A fund’s investments in certain companies may be susceptible to various factors that may impact their businesses or operations, including costs associated with government budgetary constraints that impact publicly funded projects and initiatives, the effects of general economic conditions throughout the world, increased competition from other providers of services, unfavorable tax laws or accounting policies and high leverage.

Small- and Mid-Cap Investing. The value of securities of small to medium size, less well-known issuers can be more volatile than that of relatively larger issuers and can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. Smaller issuers can have more limited product lines, markets, and financial resources.

Other Investment Strategies

In addition to the principal investment strategies discussed above, the Adviser may lend the fund's securities to broker-dealers or other institutions to earn income for the fund.

Shareholder Notice

The following is subject to change only upon 60 days' prior notice to shareholders:

Fidelity^® Sustainability U.S. Equity Fund normally invests at least 80% of the fund’s assets in equity securities of U.S. companies that the Adviser believes have proven or improving sustainability practices, based on an evaluation of such companies’ individual ESG profile.

Valuing Shares

The fund is open for business each day the NYSE is open.

Policies regarding excessive trading may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.

Fair value pricing is based on subjective judgments and it is possible that the fair value of a security may differ materially from the value that would be realized if the security were sold.

Principal Investment Strategies

Normally investing primarily in equity securities.

Normally investing at least 80% assets in equity securities of U.S. companies that Fidelity Management & Research Company LLC (FMR) believes have proven or improving sustainability practices based on an evaluation of such companies' individual environmental, social, and governance (ESG) profile.

Using FMR’s proprietary ESG ratings process to evaluate the current state of a company’s sustainability practices using a data-driven framework that includes both proprietary and third-party data, and also provide a qualitative forward looking assessment of a company’s sustainability outlook provided by FMR’s fundamental research analysts and ESG team.

FMR’s ESG ratings of companies are derived from multiple factors, including a company’s environmental profile, which may include, but is not limited to, carbon and toxic emissions, water management, waste management, vulnerability to the physical impacts of climate change, and research and investment into products, services, and energies that reduce emissions and/or provide opportunities to achieve a low carbon transition. An assessment of a firm’s social profile includes, but is not limited to, its approach to diversity and inclusion, human capital management, data privacy, product safety and human rights. With respect to governance, the independence and diversity of a company’s board, its compensation practices and board oversight of critical ESG issues are considered as part of the assessment. These factors are weighted based on how material FMR believes each factor is to a company’s financial outlook, and not all factors may be applicable to all companies.

Investing in companies that FMR believes deliver tangible environmental or social impact through core business operations. An assessment of the impact characteristics of a company may involve corporate engagement and an analysis of company alignment with the United Nations Sustainable Development Goals using qualitative analysis as well as proprietary or third-party data. For example, companies that provide access to clean water, education, or clean energy through their core business may be considered to deliver tangible impact.

Investing in securities of domestic and foreign issuers.

In addition to the ESG ratings process, using fundamental analysis of factors such as each issuer's financial condition and industry position, as well as market and economic conditions, to select investments.

Principal Investment Risks

Stock Market Volatility. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.

Sustainability Risk. The fund’s adherence to its ESG ratings process may affect the fund’s exposure to certain companies, sectors, regions, and countries and may affect the fund’s performance depending on whether such investments are in or out of favor. Adhering to the ESG ratings process may also affect the fund’s performance relative to similar funds that do not adhere to such criteria or apply such analysis. The criteria related to the fund’s ESG ratings process may result in the fund forgoing opportunities to buy certain securities when it might otherwise be advantageous to do so, or selling securities for ESG reasons when it might be otherwise disadvantageous for it to do so. There are significant differences in interpretations of what it means for a company to have positive ESG factors. While the Adviser believes its definitions are reasonable, the portfolio decisions it makes may differ with other investors’ or advisers’ views.

Foreign Exposure. Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.

Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

Small- and Mid-Cap Investing. The value of securities of small to medium size, less well-known issuers can perform differently from the market as a whole and other types of stocks and can be more volatile than that of larger issuers.

Management Risk. The Adviser’s application of the fund’s strategy criteria may not achieve its intended results. The fund could underperform in comparison to other funds with a similar benchmark or similar objectives and investment strategies.

Performance history will be available for the fund after the fund has been in operation for one calendar year.

Price to Buy

The price to buy one share of Class A or Class M is its offering price or its NAV, depending on whether you pay a front-end sales charge.

If you pay a front-end sales charge, your price will be Class A’s or Class M’s offering price. When you buy Class A or Class M shares at the offering price, Fidelity deducts the appropriate sales charge and invests the rest in Class A or Class M shares of the fund. If you qualify for a front-end sales charge waiver, your price will be Class A’s or Class M’s NAV.

The offering price of Class A or Class M is its NAV plus the sales charge. The offering price is calculated by dividing Class A’s or Class M’s NAV by the difference between one and the applicable front-end sales charge percentage and rounding to the nearest cent.

Shares will be bought at the offering price or NAV, as applicable, next calculated after an order is received in proper form.

It is the responsibility of your investment professional to transmit your order to buy shares to Fidelity before the close of business on the day you place your order.

The fund has authorized certain intermediaries to accept orders to buy shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be bought at the offering price or NAV, as applicable, next calculated after the order is received by the authorized intermediary. If applicable, orders by funds of funds for which Fidelity serves as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.

The fund may stop offering shares completely or may offer shares only on a limited basis, for a period of time or permanently.

If your payment is not received and collected, your purchase may be canceled and you could be liable for any losses or fees the fund or Fidelity has incurred.

Shares can be bought or sold through investment professionals using an automated order placement and settlement system that guarantees payment for orders on a specified date.

Under applicable anti-money laundering rules and other regulations, purchase orders may be suspended, restricted, or canceled and the monies may be withheld.

Selling Shares

The price to sell one share of Class A, Class M, or Class C is its NAV, minus any applicable CDSC. The price to sell one share of Class I or Class Z is its NAV.

It is the responsibility of your investment professional to transmit your order to sell shares to Fidelity before the close of business on the day you place your order.

The fund has authorized certain intermediaries to accept orders to sell shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be sold at the NAV next calculated after the order is received by the authorized intermediary, minus any applicable CDSC. If applicable, orders by funds of funds for which Fidelity serves as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.

See "Policies Concerning the Redemption of Fund Shares" below for additional redemption information.

When you wish to sell more than $100,000 worth of shares.
When the address on your account (record address) has changed within the last 15 days or you are requesting that a check be mailed to an address different than the record address.
When you are requesting that redemption proceeds be paid to someone other than the account owner.
In certain situations when the redemption proceeds are being transferred to a Fidelity^® account with a different registration.

When you place an order to sell shares, note the following:

Redemption proceeds (other than exchanges) may be delayed until money from prior purchases sufficient to cover your redemption has been received and collected.
Redemptions may be suspended or payment dates postponed when the NYSE is closed (other than weekends or holidays), when trading on the NYSE is restricted, or as permitted by the SEC.

Redemption proceeds may be paid in securities or other property rather than in cash if the Adviser determines it is in the best interests of the fund.

You will not receive interest on amounts represented by uncashed redemption checks.
Under applicable anti-money laundering rules and other regulations, redemption requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.

Class Z:

Policies Concerning the Redemption of Fund Shares

Converting Shares

The fund will automatically convert your class of shares of the fund to Class Z shares, if Class Z of the fund is available under your plan.

Exchanging Shares

An exchange involves the redemption of all or a portion of the shares of one fund and the purchase of shares of another fund.

However, you should note the following policies and restrictions governing exchanges:

The exchange limit may be modified for accounts held by certain institutional retirement plans to conform to plan exchange limits and Department of Labor regulations. See your retirement plan materials for further information.
The fund may refuse any exchange purchase for any reason. For example, the fund may refuse exchange purchases by any person or group if, in the Adviser's judgment, the fund would be unable to invest the money effectively in accordance with its investment objective and policies, or would otherwise potentially be adversely affected.
An exchange of shares is not subject to any applicable CDSCs.
Before any exchange, read the prospectus for the shares you are purchasing, including any purchase and sale requirements.
The shares you are acquiring by exchange must be available for sale in your state.
Exchanges may have tax consequences for you if you own shares in a taxable account.
