Investment Objective Fidelity® Emerging Markets Multifactor ETF seeks to provide investment returns that correspond, before fees and expenses, generally to the performance of the Fidelity Emerging Markets Multifactor Index℠. Fee Table The following table describes the fees and expenses that may be incurred when you buy, hold, and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. Shareholder fees 0 Annual Operating Expenses 0.0025 0 0.0003 0.0028 -0.0001 0.0027 February 28, 2026 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 the 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: 28 89 156 354 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. During the most recent fiscal year, the fund's portfolio turnover rate was 65 % of the average value of its portfolio. 0.65 Principal Investment Strategies Normally investing at least 80% of assets in securities included in the Fidelity Emerging Markets Multifactor Index℠ and in depositary receipts representing securities included in the index. The Fidelity Emerging Markets Multifactor Index℠ is designed to reflect the performance of stocks of large- and mid-capitalization emerging markets companies that have attractive valuations, high quality profiles, positive momentum signals, lower volatility than the broader emerging markets equity market, and lower correlation to the U.S. equity market. Emerging markets include countries that have an emerging stock market as defined by MSCI, countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets that the Adviser identifies as having similar emerging markets characteristics. The Fidelity Emerging Markets Multifactor Index SM is constructed using Fidelity's rules-based proprietary index methodology. Stocks in the universe are given a composite score based on four factors: valuation, quality, momentum, and volatility. Stocks with the highest composite scores within each sector and country are identified for inclusion in the index. Within each sector, stocks are weighted based on their market capitalization in the broader emerging markets equity market plus an overweight adjustment that is equal for all constituents within that sector. The index will overweight the five sectors with the lowest correlation to U.S. large capitalization stocks and underweight the six sectors with the highest correlation to U.S. large capitalization stocks. Effective December 11, 2025, derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives. Lending securities to earn income for the fund. Principal Investment Risks Stock Market Volatility. Stock markets and, as a result, stock market indexes, 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 and Emerging Markets Risk. Foreign markets, particularly emerging 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. The extent of economic development; political stability; market depth, infrastructure, and capitalization; and regulatory oversight can be less than in more developed markets. Emerging markets typically have less established legal, accounting and financial reporting systems than those in more developed markets, which may reduce the scope or quality of financial information available to investors. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile. Foreign exchange rates also can be extremely volatile. Geographic Exposure to Asia. Because the fund invests a meaningful portion of its assets in Asia, the fund's performance is expected to be closely tied to social, political, and economic conditions within Asia and to be more volatile than the performance of more geographically diversified funds. Geographic Exposure to China. Because the fund invests a meaningful portion of its assets in China, the fund's performance is expected to be closely tied to social, political, and economic conditions in China and to be more volatile than the performance of more geographically diversified funds. The fund may obtain exposure to companies based or operated in China by investing through legal structures known as variable interest entities (VIEs). Instead of directly owning the equity securities of a Chinese company, a VIE enters into service and other contracts with the Chinese company. Although the VIE has no equity ownership of the Chinese company, the contractual arrangements permit the VIE to consolidate the Chinese company into its financial statements. Intervention by the Chinese government with respect to VIEs could significantly affect the Chinese company's performance and the enforceability of the VIE's contractual arrangements with the Chinese company. Geographic Exposure to the China Region. Because the fund invests a meaningful portion of its assets in the China region, the fund's performance is expected to be closely tied to social, political, and economic conditions within the China region and to be more volatile than the performance of more geographically diversified funds. 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. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending transaction) can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's value or result in delays in recovering securities and/or capital from a counterparty. Fluctuation of Net Asset Value and Share Price. The net asset value per share (NAV) of the fund will generally fluctuate with changes in the market value of the fund's holdings. The fund's shares can be bought and sold in the secondary market at market prices. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for the fund's shares may result in the fund's shares trading significantly above (at a premium) or below (at a discount) to NAV. Given the nature of the relevant markets for certain of the fund's securities, shares may trade at a larger premium or discount to the NAV than shares of other ETFs. In addition, in stressed market conditions or periods of market disruption or volatility, the market for shares may become less liquid in response to deteriorating liquidity in the markets for the fund's underlying portfolio holdings. Correlation to Index. The performance of the fund and its underlying index may vary somewhat due to factors such as fees and expenses of the fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may not be identified and corrected for some period of time, which may have an adverse impact on the fund and its shareholders. Passive Management Risk. The fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of the fund's index or of the actual securities included in the index. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the fund's performance could be lower than actively managed funds that may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline or a decline in the value of one or more issuers. The fund will be concentrated to approximately the same extent that the fund's index concentrates in the securities of issuers in a particular industry. Factor-Based Strategy Risk. Although the fund's underlying index uses a rules-based proprietary index methodology that seeks to identify certain factors, there is no guarantee that this methodology will be successful. Trading Issues. There can be no assurance that an active trading market will be maintained. Market makers and Authorized Participants are not obligated to make a market in the fund's shares or to submit purchase and redemption orders for creation units. Decisions by market makers or Authorized Participants to reduce their role with respect to market making or creation and redemption activities during times of market stress, or a decline in the number of Authorized Participants due to decisions to exit the business, bankruptcy, or other factors, could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying value of the fund's portfolio securities and the market price of fund shares. In addition, trading may be halted, for example, due to market conditions. Cash Transactions Risk. Unlike certain ETFs, the fund may effect some or all creations and redemptions using cash, rather than in-kind securities. As a result, an investment in the fund may be less tax-efficient than an investment in an ETF that distributes portfolio securities entirely in-kind. Mid Cap Investing. The value of securities of 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. Securities Lending Risk. Securities lending involves the risk that the borrower may fail to return the securities loaned in a timely manner or at all. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. 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.

Fee Table The following table describes the fees and expenses that may be incurred when you buy, hold, and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. Shareholder fees 0 Annual Operating Expenses 0.0018 0 0.0001 0.0019 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 the 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: 19 61 107 243 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. During the most recent fiscal year, the fund's portfolio turnover rate was 63 % of the average value of its portfolio. 0.63 Principal Investment Strategies Normally investing at least 80% of assets in securities included in the Fidelity International High Dividend IndexSM and in depositary receipts representing securities included in the index. The index is designed to reflect the performance of stocks of large- and mid-capitalization developed international high dividend-paying companies that are expected to continue to pay and grow their dividends. The Fidelity International High Dividend Index SM is constructed using Fidelity's rules-based proprietary index methodology. Stocks in the universe are grouped together by country and sector (with certain broader groupings in the event of small sector and country combinations). Stocks are ranked within each group and given a composite score based on three fundamental characteristics: high dividend yield, low dividend payout ratio, and high dividend growth. Within each group, composite scores are adjusted to remove size bias. Stocks with the highest composite scores within each group are identified for inclusion in the index. The grouping methodology results in country weights that are comparable to but not exactly the same as the broader developed international equity market. Within each group, each stock is weighted based on its market capitalization in the broader equity market plus an overweight adjustment that is equal for all constituents within that group. Sectors are weighted relative to the broader developed international equity market depending on the yield characteristics of the sector. Sectors with higher dividend yields are overweighted, while those with lower dividend yields are underweighted. Effective December 11, 2025, derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives. Lending securities to earn income for the fund. Principal Investment Risks Stock Market Volatility. Stock markets and, as a result, stock market indexes, 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. Foreign exchange rates also can be extremely volatile. Geographic Exposure to Europe. Because the fund invests a meaningful portion of its assets in Europe, the fund's performance is expected to be closely tied to social, political, and economic conditions within Europe and to be more volatile than the performance of more geographically diversified funds. Geographic Exposure to the Pacific Basin. Because the fund invests a meaningful portion of its assets in the Pacific Basin, the fund's performance is expected to be closely tied to social, political, and economic conditions within the Pacific Basin and to be more volatile than the performance of more geographically diversified funds. 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. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending transaction) can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's value or result in delays in recovering securities and/or capital from a counterparty. Fluctuation of Net Asset Value and Share Price. The net asset value per share (NAV) of the fund will generally fluctuate with changes in the market value of the fund's holdings. The fund's shares can be bought and sold in the secondary market at market prices. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for the fund's shares may result in the fund's shares trading significantly above (at a premium) or below (at a discount) to NAV. Given the nature of the relevant markets for certain of the fund's securities, shares may trade at a larger premium or discount to the NAV than shares of other ETFs. In addition, in stressed market conditions or periods of market disruption or volatility, the market for shares may become less liquid in response to deteriorating liquidity in the markets for the fund's underlying portfolio holdings. Correlation to Index. The performance of the fund and its underlying index may vary somewhat due to factors such as fees and expenses of the fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may not be identified and corrected for some period of time, which may have an adverse impact on the fund and its shareholders. Passive Management Risk. The fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of the fund's index or of the actual securities included in the index. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the fund's performance could be lower than actively managed funds that may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline or a decline in the value of one or more issuers. The fund will be concentrated to approximately the same extent that the fund's index concentrates in the securities of issuers in a particular industry or group of industries. Trading Issues. There can be no assurance that an active trading market will be maintained. Market makers and Authorized Participants are not obligated to make a market in the fund's shares or to submit purchase and redemption orders for creation units. Decisions by market makers or Authorized Participants to reduce their role with respect to market making or creation and redemption activities during times of market stress, or a decline in the number of Authorized Participants due to decisions to exit the business, bankruptcy, or other factors, could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying value of the fund's portfolio securities and the market price of fund shares.

If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Dividend Paying Securities. Although the fund's underlying index uses a rules-based proprietary index methodology that is designed to identify stocks of dividend-paying companies that will continue to pay and grow their dividends, there is no guarantee that this methodology will be successful. The fund may underperform funds that invest more broadly. If securities held by the fund reduce or stop paying dividends, the fund's ability to generate dividend income may be affected. 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.

The Fidelity International Multifactor Index℠ is designed to reflect the performance of stocks of large- and mid-capitalization developed international companies that have attractive valuations, high quality profiles, positive momentum signals, lower volatility than the broader developed international equity market, and lower correlation to the U.S. equity market. The Fidelity International Multifactor Index SM is constructed using Fidelity's rules-based proprietary index methodology. Stocks in the universe are given a composite score based on four factors: valuation, quality, momentum, and volatility. Stocks with the highest composite scores within each sector and country are identified for inclusion in the index. Within each sector, stocks are weighted based on their market capitalization in the broader developed international equity market plus an overweight adjustment that is equal for all constituents within that sector. The index will overweight the five sectors with the lowest correlation to U.S. large capitalization stocks and underweight the six sectors with the highest correlation to U.S. large capitalization stocks. Effective December 11, 2025, derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives.
