     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 and if you hold your shares:

     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.

     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 and if you hold your shares:

     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

     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 and if you hold your shares:

     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 
      
       
       
     
       
       15

      Normally investing a majority of assets in common stocks with a focus on those that pay current dividends and show potential for capital appreciation. 
      Potentially investing in bonds, including lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds), as well as stocks that are not currently paying dividends, but offer prospects for future income or capital appreciation. 
      Investing in 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. 
      Effective December 11, 2025, normally investing at least 80% of assets in a combination of securities of growth companies and income-producing securities. 
      
     Growth companies are companies the Adviser believes have above average growth potential. The Adviser considers a number of factors in determining a company's growth potential, such as whether the company is included in a third-party growth benchmark or classified as a growth company by a third-party vendor, if the company's projected earnings per share growth, sales growth per share or free cash flow growth or its trailing earnings per share growth is above the equity market median, if the company's research and development expenses exceed sales, general and administrative expenses, or if the company is raising capital to grow, fund or expand its business. A company's growth potential can be determined under any of these factors. 
     Income-producing securities are securities that pay, or are expected to pay within the next three months, dividends or interest. 
     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. 
     
      
     Reorganization . The Board of Trustees of Fidelity Advisor Series I has unanimously approved an Agreement and Plan of Reorganization ("Agreement") between Fidelity Advisor &#xae; Growth &amp; Income Fund and Fidelity &#xae; Growth &amp; Income Portfolio pursuant to which Fidelity Advisor &#xae; Growth &amp; Income Fund would be reorganized on a tax-free basis with and into Fidelity &#xae; Growth &amp; Income Portfolio.  
     &#160;  
     Each fund seeks high total return through a combination of current income and capital appreciation.  
     &#160;  
     As a result of the Reorganization, shareholders of each class of Fidelity Advisor &#xae; Growth &amp; Income Fund will receive shares of the corresponding class of Fidelity &#xae; Growth &amp; Income Portfolio.  
     &#160;  
     The Agreement provides for the transfer of all of the assets and the assumption of all of the liabilities of Fidelity Advisor &#xae; Growth &amp; Income Fund in exchange for corresponding shares of Fidelity &#xae; Growth &amp; Income Portfolio equal in total value to the total value of shares of Fidelity Advisor &#xae; Growth &amp; Income Fund. After the exchange, Fidelity Advisor &#xae; Growth &amp; Income Fund will distribute the Fidelity &#xae; Growth &amp; Income Portfolio shares to its shareholders pro rata, in liquidation of Fidelity Advisor &#xae; Growth &amp; Income Fund. As a result, shareholders of Fidelity Advisor &#xae; Growth &amp; Income Fund will become shareholders of Fidelity &#xae; Growth &amp; Income Portfolio (these transactions are referred to as the "Reorganization").  
     &#160; 
     The Reorganization, which does not require shareholder approval, is expected to take place on or about March 28, 2025. The Reorganization is expected to be a tax-free transaction. This means that neither Fidelity Advisor &#xae; Growth &amp; Income Fund nor its shareholders will recognize any gain or loss as a direct result of the Reorganization.  
     &#160;  
     Effective after the close of business on or about March 27, 2025, new positions in the fund may no longer be opened. Existing shareholders may continue to hold their shares and purchase additional shares through the reinvestment of dividend and capital gain distributions until the fund's Reorganization takes place.

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

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 and if you hold your shares:

     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.

      Normally investing primarily in common stocks. 
      Investing in securities of companies that Fidelity Management &amp; Research Company LLC (FMR) believes are undervalued in the marketplace in relation to factors such as assets, sales, earnings, or growth potential (stocks of these companies are often called "value" stocks). 
      Focusing investments in medium-sized companies, but also may invest substantially in larger or smaller companies. 
      Investing in domestic and foreign issuers. 
      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. 
      Effective December 11, 2025, normally investing at least 80% of assets in securities of value companies.&#160; 
      
     Value companies are companies the Adviser believes are undervalued in the marketplace. The Adviser considers traditional and other measures of value, such as whether the company is included in a third-party value benchmark or classified as a value company by a third-party vendor, whether the company's free cash flow yield is above the equity market median, whether the company's enterprise value (the total value of a company's outstanding equity and debt) relative to earnings is below the equity market median, or whether the company's price-to-book (P/B) ratio or projected price-to-earnings (P/E) ratio is below the equity market median. An issuer may be determined to be a value company under any of these factors. 
     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.

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 and if you hold your shares:

     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

     Equity securities represent an ownership interest, or the right to acquire an ownership interest, in an issuer. Equity securities include common stocks (including depositary receipts evidencing ownership of common stock), preferred stocks and other preferred securities, convertible securities, rights and warrants, and other securities, such as hybrid securities and trust preferred securities, believed to have equity-like characteristics. 
     Growth companies are companies the Adviser believes have above average growth potential. The Adviser considers a number of factors in determining a company's growth potential, such as whether the company is included in a third-party growth benchmark or classified as a growth company by a third-party vendor, if the company's projected earnings per share growth, sales growth per share or free cash flow growth or its trailing earnings per share growth is above the equity market median, if the company's research and development expenses exceed sales, general and administrative expenses, or if the company is raising capital to grow, fund or expand its business. A company's growth potential can be determined under any of these factors. 
     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.

     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 and if you hold your shares:

     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

      Normally investing at least 80% of assets in equity securities. 
      Normally investing primarily in income-producing equity securities, which tends to lead to investments in large cap "value" stocks. 
      Potentially investing in other types of equity securities and debt securities, including lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds). 
      Investing in domestic and foreign issuers. 
      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. 
      Potentially using covered call options as tools in managing the fund's assets.

     Equity securities represent an ownership interest, or the right to acquire an ownership interest, in an issuer. Equity securities include common stocks (including depositary receipts evidencing ownership of common stock), preferred stocks and other preferred securities, convertible securities, rights and warrants, and other securities, such as hybrid securities and trust preferred securities, believed to have equity-like characteristics. 
     Income-producing equity securities are equity securities that pay, or are expected to pay within the next three months, dividends or interest.&#160;

     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:

     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.

      Normally investing primarily in common stocks. 
      Investing in securities of companies that Fidelity Management &amp; Research Company LLC (FMR) believes are undervalued in the marketplace in relation to factors such as assets, sales, earnings, or growth potential (stocks of these companies are often called "value" stocks). 
      Focusing investments in medium-sized companies, but also may invest substantially in larger or smaller companies. 
      Investing in domestic and foreign issuers. 
      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. 
      Effective December 11, 2025, normally investing at least 80% of assets in securities of value companies.&#160; 
      
     Value companies are companies the Adviser believes are undervalued in the marketplace. The Adviser considers traditional and other measures of value, such as whether the company is included in a third-party value benchmark or classified as a value company by a third-party vendor, whether the company's free cash flow yield is above the equity market median, whether the company's enterprise value (the total value of a company's outstanding equity and debt) relative to earnings is below the equity market median, or whether the company's price-to-book (P/B) ratio or projected price-to-earnings (P/E) ratio is below the equity market median. An issuer may be determined to be a value company under any of these factors. 
     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.

     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 and if you hold your shares:

     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.

      Investing in domestic and foreign issuers.

      Effective December 11, 2025, normally investing at least 80% of assets in securities of growth companies. 
      
     Growth companies are companies the Adviser believes have above average growth potential. The Adviser considers a number of factors in determining a company's growth potential, such as whether the company is included in a third-party growth benchmark or classified as a growth company by a third-party vendor, if the company's projected earnings per share growth, sales growth per share or free cash flow growth or its trailing earnings per share growth is above the equity market median, if the company's research and development expenses exceed sales, general and administrative expenses, or if the company is raising capital to grow, fund or expand its business. A company's growth potential can be determined under any of these factors. 
     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.

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.

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.

      Focusing investments in medium-sized companies, but also may invest substantially in larger or smaller companies. 
      Investing in domestic and foreign issuers. 
      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. 
      Effective December 11, 2025, normally investing at least 80% of assets in securities of value companies.&#160; 
      
     Value companies are companies the Adviser believes are undervalued in the marketplace. The Adviser considers traditional and other measures of value, such as whether the company is included in a third-party value benchmark or classified as a value company by a third-party vendor, whether the company's free cash flow yield is above the equity market median, whether the company's enterprise value (the total value of a company's outstanding equity and debt) relative to earnings is below the equity market median, or whether the company's price-to-book (P/B) ratio or projected price-to-earnings (P/E) ratio is below the equity market median. An issuer may be determined to be a value company under any of these factors. 
     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.

     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.

      Normally investing at least 80% of assets in equity securities. 
      Normally investing primarily in common stocks. 
      Investing in companies that Fidelity Management &amp; Research Company LLC (FMR) believes have above-average growth potential (stocks of these companies are often called "growth" stocks). 
      Investing in domestic and foreign issuers. 
      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. 
      Effective December 11, 2025, normally investing at least 80% of assets in equity securities of growth companies. 
      
     Equity securities represent an ownership interest, or the right to acquire an ownership interest, in an issuer. Equity securities include common stocks (including depositary receipts evidencing ownership of common stock), preferred stocks and other preferred securities, convertible securities, rights and warrants, and other securities, such as hybrid securities and trust preferred securities, believed to have equity-like characteristics. 
     Growth companies are companies the Adviser believes have above average growth potential. The Adviser considers a number of factors in determining a company's growth potential, such as whether the company is included in a third-party growth benchmark or classified as a growth company by a third-party vendor, if the company's projected earnings per share growth, sales growth per share or free cash flow growth or its trailing earnings per share growth is above the equity market median, if the company's research and development expenses exceed sales, general and administrative expenses, or if the company is raising capital to grow, fund or expand its business. A company's growth potential can be determined under any of these factors. 
     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.

     In addition, the fund is classified as non-diversified under the Investment Company Act of 1940 (1940 Act), which means that it has the ability to invest a greater portion of assets in securities of a smaller number of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a more diversified fund.

     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:

     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

     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 and if you hold your shares:

     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

      Normally investing at least 80% of assets in equity securities. 
      Normally investing primarily in common stocks. 
      Investing in securities of companies that Fidelity Management &amp; Research Company LLC (FMR) believes are undervalued in the marketplace in relation to factors such as assets, sales, earnings, growth potential, or cash flow, or in relation to securities of other companies in the same industry (stocks of these companies are often called "value" stocks). 
      Investing in domestic and foreign issuers. 
      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. 
      Effective December 11, 2025, normally investing at least 80% of assets in equity securities of value companies. 
      
     Equity securities represent an ownership interest, or the right to acquire an ownership interest, in an issuer. Equity securities include common stocks (including depositary receipts evidencing ownership of common stock), preferred stocks and other preferred securities, convertible securities, rights and warrants, and other securities, such as hybrid securities and trust preferred securities, believed to have equity-like characteristics. 
     Value companies are companies the Adviser believes are undervalued in the marketplace. The Adviser considers traditional and other measures of value, such as whether the company is included in a third-party value benchmark or classified as a value company by a third-party vendor, whether the company's free cash flow yield is above the equity market median, whether the company's enterprise value (the total value of a company's outstanding equity and debt) relative to earnings is below the equity market median, or whether the company's price-to-book (P/B) ratio or projected price-to-earnings (P/E) ratio is below the equity market median. An issuer may be determined to be a value company under any of these factors. 
     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. 
     
      
     Proposed Reorganization. &#160; The Board of Trustees of Fidelity Advisor Series I has unanimously approved an Agreement and Plan of Reorganization ("Agreement") between Fidelity Advisor &#xae; Equity Value Fund and Fidelity &#xae; Value Discovery Fund pursuant to which Fidelity Advisor &#xae; Equity Value Fund would be reorganized on a tax-free basis with and into Fidelity &#xae; Value Discovery Fund. 
     As a result of the proposed Reorganization, shareholders of Fidelity Advisor &#xae; Equity Value Fund would receive, respectively, corresponding shares of Fidelity &#xae; Value Discovery Fund. 
     The Agreement provides for the transfer of all of the assets of Fidelity Advisor &#xae; Equity Value Fund in exchange for corresponding shares of Fidelity &#xae; Value Discovery Fund equal in value to the net assets of Fidelity Advisor &#xae; Equity Value Fund and the assumption by Fidelity &#xae; Value Discovery Fund of all of the liabilities of Fidelity Advisor &#xae; Equity Value Fund. After the exchange, Fidelity Advisor &#xae; Equity Value Fund will distribute the Fidelity &#xae; Value Discovery Fund shares to its shareholders pro rata, in liquidation of Fidelity Advisor &#xae; Equity Value Fund. As a result, shareholders of Fidelity Advisor &#xae; Equity Value Fund will become shareholders of Fidelity &#xae; Value Discovery Fund (these transactions are collectively referred to as the "Reorganization"). 
     A Special Meeting (the "Meeting") of the Shareholders of Fidelity Advisor &#xae; Equity Value Fund is expected to be held during the second quarter of 2025 and approval of the Agreement will be voted on at that time. A combined proxy statement and prospectus containing more information with respect to the Reorganization will be provided to shareholders of record of Fidelity Advisor &#xae; Equity Value Fund in advance of the meeting. 
     If the Agreement is approved at the Meeting and certain conditions required by the Agreement are satisfied, the Reorganization is expected to take place on or about June 6, 2025. If shareholder approval of the Agreement is delayed due to failure to meet a quorum or otherwise, the Reorganization will become effective, if approved, as soon as practicable thereafter. 
     Effective after the close of business on the business day prior to the Reorganization, new positions in the fund may no longer be opened. Existing shareholders may continue to hold their shares and purchase additional shares through the reinvestment of dividend and capital gain distributions until the fund's Reorganization takes place. 
     The foregoing is not a solicitation of any proxy. For a free copy of the Proxy Statement describing the Reorganization (and containing important information about fees, expenses and risk considerations) and a Prospectus for Fidelity &#xae; Value Discovery Fund please call 1-800-544-8544. The prospectus/proxy statement will also be available for free on the Securities and Exchange Commission's web site (www.sec.gov).

     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.

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.

      Normally investing at least 80% of assets in real estate related investments of all types. 
      Investing primarily in real estate related instruments of domestic and foreign issuers, with an emphasis on lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds). 
      Normally investing at least 65% of total assets in commercial and residential mortgage-backed securities; debt securities of real estate entities; equity securities of entities whose primary assets are mortgage loans or commercial or residential mortgage-backed securities; and preferred stock of real estate investment trusts (REITs). 
      Normally investing at least 90% of net assets in commercial and residential mortgage-backed securities; debt securities of real estate entities; equity securities of entities whose primary assets are mortgage loans or commercial or residential mortgage-backed securities; preferred stock of real estate investment trusts (REITs); U.S. Government securities; cash equivalents; and related futures and options. 
      Normally investing more than 25% of total assets in securities and instruments backed by real estate and real estate mortgages and securities of companies engaged in the real estate business, including interests in REITs. 
      Investing the fund's assets without limitation in lower-rated securities and non-rated securities of lower quality. 
      In selecting investments, analyzing a security's structural features, current pricing and trading opportunities, and the credit quality of its issuer or the underlying assets, as well as using fundamental analysis of each issuer's financial condition. 
      Effective December 11, 2025, normally investing at least 80% of assets in a combination of real estate related investments of all types and below investment grade debt securities of real estate related investments. 
      
     A real estate entity or real estate related investment is any company that is principally engaged in the real estate industry and includes commercial and residential mortgage-backed securities; debt securities of real estate entities; equity securities of entities whose primary assets are mortgage loans or commercial or residential mortgage-backed securities; REITs that either own properties or make construction loans and preferred stocks of REITs; real estate developers; companies with substantial real estate holdings; and other companies whose products and services are related to the real estate industry, such as building supply manufacturers, mortgage lenders, or mortgage servicing companies. The Adviser considers a company to be principally engaged in the real estate industry if (i) at least 50% of its assets, income, sales or profits are committed to, or derived from, the real estate industry, or (ii) a third party has given the company an industry or sector classification consistent with the real estate industry. 
      
       Debt securities are used by issuers to borrow money. The issuer usually pays a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security. Debt securities include corporate bonds, government securities (including Treasury securities), repurchase agreements, money market securities, mortgage and other asset-backed securities, loans and loan participations, and other securities, such as hybrids and synthetic securities, believed to have debt-like characteristics (e.g., securities classified as Tier 2 Regulatory capital, securities that rank above share capital in an insolvency waterfall, securities with maturity dates and non-cancellable interest payment structures).&#160; 
     Below investment grade debt securities are debt securities that are rated below BBB- or its equivalent by at least one nationally recognized statistical ratings organization (NRSRO), or, if unrated, determined by the Adviser to be of comparable quality. 
     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.

     Changes in real estate values or economic downturns can have a significant negative effect on issuers in the real estate industry.

     Lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds) and certain types of other securities involve greater risk of default or price changes due to changes in the credit quality of the issuer. 
     The value of lower-quality debt securities and certain types of other securities can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments and can be difficult to resell.

     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 and if you hold your shares:

     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:

     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.

      Normally investing primarily in common stocks. 
      Investing in companies that Fidelity Management &amp; Research Company LLC (FMR) believes have above-average growth potential (stocks of these companies are often called "growth" stocks). 
      Investing in domestic and foreign issuers. 
      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. 
      Effective December 11, 2025, normally investing at least 80% of assets in securities of growth companies. 
      
     Growth companies are companies the Adviser believes have above average growth potential. The Adviser considers a number of factors in determining a company's growth potential, such as whether the company is included in a third-party growth benchmark or classified as a growth company by a third-party vendor, if the company's projected earnings per share growth, sales growth per share or free cash flow growth or its trailing earnings per share growth is above the equity market median, if the company's research and development expenses exceed sales, general and administrative expenses, or if the company is raising capital to grow, fund or expand its business. A company's growth potential can be determined under any of these factors. 
     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.

     In addition, the fund is classified as non-diversified under the Investment Company Act of 1940 (1940 Act), which means that it has the ability to invest a greater portion of assets in securities of a smaller number of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a more diversified fund.

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

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 and if you hold your shares:

     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

      Effective December 11, 2025, normally investing at least 80% of assets in equity securities of dividend growth companies. 
      
     Equity securities represent an ownership interest, or the right to acquire an ownership interest, in an issuer. Equity securities include common stocks (including depositary receipts evidencing ownership of common stock), preferred stocks and other preferred securities, convertible securities, rights and warrants, and other securities, such as hybrid securities and trust preferred securities, believed to have equity-like characteristics. 
     Dividend growth companies are companies that the Adviser believes have favorable prospects to pay and grow dividends over time. The Adviser considers a number of factors in determining whether a company is growing dividends, such as whether the company has positive trailing one-year, three-year, or five-year dividend growth per share, whether a company pays dividends and has a year-over-year decrease in shares outstanding due to share buybacks, or whether the company pays dividends and free cash flow is projected to grow. An issuer may be determined to be a dividend growth company under any of these factors. 
     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. 
     
      
     Proposed Reorganization. &#160;The Board of Trustees of Fidelity Advisor Series I has unanimously approved an Agreement and Plan of Reorganization ("Agreement") between Fidelity Advisor &#xae; &#160;Dividend Growth Fund and Fidelity &#xae; Dividend Growth Fund pursuant to which Fidelity Advisor &#xae; &#160;Dividend Growth Fund would be reorganized on a tax-free basis with and into Fidelity &#xae; Dividend Growth Fund. 
     As a result of the proposed Reorganization, shareholders of Fidelity Advisor &#xae; Dividend Growth Fund would receive, respectively, corresponding shares of Fidelity &#xae; Dividend Growth Fund. 
     The Agreement provides for the transfer of all of the assets of Fidelity Advisor &#xae; Dividend Growth Fund in exchange for corresponding shares of Fidelity &#xae; Dividend Growth Fund equal in value to the net assets of Fidelity Advisor &#xae; Dividend Growth Fund and the assumption by Fidelity &#xae; Dividend Growth Fund of all of the liabilities of Fidelity Advisor &#xae; Dividend Growth Fund. After the exchange, Fidelity Advisor &#xae; Dividend Growth Fund will distribute the Fidelity &#xae; Dividend Growth Fund shares to its shareholders pro rata, in liquidation of Fidelity Advisor &#xae; Dividend Growth Fund. As a result, shareholders of Fidelity Advisor &#xae; Dividend Growth Fund will become shareholders of Fidelity &#xae; Dividend Growth Fund (these transactions are collectively referred to as the "Reorganization"). 
     A Special Meeting (the "Meeting") of the Shareholders of Fidelity Advisor &#xae; Dividend Growth Fund is expected to be held during the second quarter of 2025 and approval of the Agreement will be voted on at that time. A combined proxy statement and prospectus containing more information with respect to the Reorganization will be provided to shareholders of record of Fidelity Advisor &#xae; Dividend Growth Fund in advance of the meeting. 
     If the Agreement is approved at the Meeting and certain conditions required by the Agreement are satisfied, the Reorganization is expected to take place on or about June 6, 2025. If shareholder approval of the Agreement is delayed due to failure to meet a quorum or otherwise, the Reorganization will become effective, if approved, as soon as practicable thereafter. 
     Effective after the close of business on the business day prior to the Reorganization, new positions in the fund may no longer be opened. Existing shareholders may continue to hold their shares and purchase additional shares through the reinvestment of dividend and capital gain distributions until the fund's Reorganization takes place. 
     The foregoing is not a solicitation of any proxy. For a free copy of the Proxy Statement describing the Reorganization (and containing important information about fees, expenses and risk considerations) and a Prospectus for Fidelity &#xae; Dividend Growth Fund please call 1-800-544-8544. The prospectus/proxy statement will also be available for free on the Securities and Exchange Commission's web site (www.sec.gov) .

     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.

     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
