     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:

     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.

     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.

     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. 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.

     Consumer discretionary products and services are non-essential products and services whose demand tends to increase as consumers' disposable income increases, such as automobiles, apparel, electronics, home furnishings, and travel and leisure products and services. 
     These companies may include, for example, on-line retailers; department stores and specialty retailers including apparel, electronics, automotive, and home furnishing stores; manufacturers of auto parts and accessories, tire and rubber, autos, motorcycles, and scooters; manufacturers of consumer electronic products, including TVs and home audio equipment; manufacturers of household appliances and home furnishings; residential construction companies; manufacturers of leisure products; manufacturers of apparel, accessories, footwear, textiles, and luxury goods; gaming facility, hotel, cruise and travel agency owners and operators; restaurants and caterers; and companies providing educational, home security, legal, and personal services. 
     Fidelity may consider a company to be principally engaged in the designated business activity or activities based on: (i) the level of a company's assets, income, sales, or profits that are committed to, derived from, or related to the designated business activity or activities, or (ii) whether a third party has given the company an industry or sector classification consistent with the designated business activity or activities. Whether a company is principally engaged in the designated business activity or activities can be determined under any of these factors. 
     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.

     Proposed Reorganization. The Board of Trustees of Fidelity Advisor Series VII has unanimously approved an Agreement and Plan of Reorganization ("Agreement") between Fidelity Advisor &#xae; Consumer Discretionary Fund and Consumer Discretionary Portfolio pursuant to which Fidelity Advisor &#xae; Consumer Discretionary Fund would be reorganized on a tax-free basis with and into Consumer Discretionary Portfolio. 
      
       As a result of the proposed Reorganization, shareholders of Fidelity Advisor &#xae; Consumer Discretionary Fund would receive, respectively, corresponding shares of Consumer Discretionary Portfolio. 
     The Agreement provides for the transfer of all of the assets of Fidelity Advisor &#xae; Consumer Discretionary Fund in exchange for corresponding shares of Consumer Discretionary Portfolio equal in value to the net assets of Fidelity Advisor &#xae; Consumer Discretionary Fund and the assumption by Consumer Discretionary Portfolio of all of the liabilities of Fidelity Advisor &#xae; Consumer Discretionary Fund. After the exchange, Fidelity Advisor &#xae; Consumer Discretionary Fund will distribute the Consumer Discretionary Portfolio shares to its shareholders pro rata, in liquidation of Fidelity Advisor &#xae; Consumer Discretionary Fund. As a result, shareholders of Fidelity Advisor &#xae; Consumer Discretionary Fund will become shareholders of Consumer Discretionary Portfolio (these transactions are collectively referred to as the "Reorganization"). 
     The Reorganization, which does not require shareholder approval, is expected to take place on or about November 14, 2025. The Reorganization is expected to be a tax-free transaction. This means that neither Fidelity Advisor &#xae; Consumer Discretionary Fund nor its shareholders will recognize any gain or loss as a direct result of the Reorganization. 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.

     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.

     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 securities of companies principally engaged in the energy field including the conventional areas of oil, gas, electricity and coal, and newer sources of energy such as nuclear, geothermal, oil shale, and solar power. 
          
        
      
     Energy products and services are those related to the exploration, extraction, production, sale, or distribution of energy resources, including oil, gas, electricity, coal, and nuclear, geothermal, and solar power. 
     These companies may include, for example, integrated oil companies; drilling contractors and rig owners; drilling rig and equipment manufacturers and providers of supplies and services to companies engaged in oil and gas drilling; companies engaged in the exploration, production, refining, marketing, storage, or transportation of oil, gas, and/or refined products; and companies involved in the production and mining of coal, related products, and other consumable fuels. 
     Fidelity may consider a company to be principally engaged in the designated business activity or activities based on: (i) the level of a company's assets, income, sales, or profits that are committed to, derived from, or related to the designated business activity or activities, or (ii) whether a third party has given the company an industry or sector classification consistent with the designated business activity or activities. Whether a company is principally engaged in the designated business activity or activities can be determined under any of these factors. 
     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.

     Proposed Reorganization. The Board of Trustees of Fidelity Advisor Series VII has unanimously approved an Agreement and Plan of Reorganization ("Agreement") between Fidelity Advisor &#xae; Energy Fund and Energy Portfolio pursuant to which Fidelity Advisor &#xae; Energy Fund would be reorganized on a tax-free basis with and into Energy Portfolio. 
      
       As a result of the proposed Reorganization, shareholders of Fidelity Advisor &#xae; Energy Fund would receive, respectively, corresponding shares of Energy Portfolio. 
     The Agreement provides for the transfer of all of the assets of Fidelity Advisor &#xae; Energy Fund in exchange for corresponding shares of Energy Portfolio equal in value to the net assets of Fidelity Advisor &#xae; Energy Fund and the assumption by Energy Portfolio of all of the liabilities of Fidelity Advisor &#xae; Energy Fund. After the exchange, Fidelity Advisor &#xae; Energy Fund will distribute the Energy Portfolio shares to its shareholders pro rata, in liquidation of Fidelity Advisor &#xae; Energy Fund. As a result, shareholders of Fidelity Advisor &#xae; Energy Fund will become shareholders of Energy Portfolio (these transactions are collectively referred to as the "Reorganization"). 
     The Reorganization, which does not require shareholder approval, is expected to take place on or about November 14, 2025. The Reorganization is expected to be a tax-free transaction. This means that neither Fidelity Advisor &#xae; Energy Fund nor its shareholders will recognize any gain or loss as a direct result of the Reorganization. 
     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.

     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.

     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. 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:

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.

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

     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

     Fidelity may consider a company to be principally engaged in the designated business activity or activities based on: (i) the level of a company's assets, income, sales, or profits that are committed to, derived from, or related to the designated business activity or activities, or (ii) whether a third party has given the company an industry or sector classification consistent with the designated business activity or activities. Whether a company is principally engaged in the designated business activity or activities can be determined under any of these factors. 
     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.

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.

     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:

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.

     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

        Normally investing at least 80% of assets in securities of companies principally engaged in offering, using, or developing products, processes, or services that will provide or will benefit significantly from technological advances and improvements. 
          
        
      
     These companies may include, for example, manufacturers of communications equipment, products, and services, personal computers and other computer hardware components and peripherals; providers of information technology and systems integration services; companies developing and producing database management, home entertainment, educational, specialty, enterprise, and business software; manufacturers of electronic equipment, instruments or components, including copiers and faxes; semiconductor and related equipment manufacturers; and other information technology companies. 
     Fidelity may consider a company to be principally engaged in the designated business activity or activities based on: (i) the level of a company's assets, income, sales, or profits that are committed to, derived from, or related to the designated business activity or activities, or (ii) whether a third party has given the company an industry or sector classification consistent with the designated business activity or activities. Whether a company is principally engaged in the designated business activity or activities can be determined under any of these factors. 
     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.

     Proposed Reorganization. The Board of Trustees of Fidelity Advisor Series VII has unanimously approved an Agreement and Plan of Reorganization ("Agreement") between Fidelity Advisor &#xae; Technology Fund and Technology Portfolio pursuant to which Fidelity Advisor &#xae; Technology Fund would be reorganized on a tax-free basis with and into Technology Portfolio. 
      
       As a result of the proposed Reorganization, shareholders of Fidelity Advisor &#xae; Technology Fund would receive, respectively, corresponding shares of Technology Portfolio. 
     The Agreement provides for the transfer of all of the assets of Fidelity Advisor &#xae; Technology Fund in exchange for corresponding shares of Technology Portfolio equal in value to the net assets of Fidelity Advisor &#xae; Technology Fund and the assumption by Technology Portfolio of all of the liabilities of Fidelity Advisor &#xae; Technology Fund. After the exchange, Fidelity Advisor &#xae; Technology Fund will distribute the Technology Portfolio shares to its shareholders pro rata, in liquidation of Fidelity Advisor &#xae; Technology Fund. As a result, shareholders of Fidelity Advisor &#xae; Technology Fund will become shareholders of Technology Portfolio (these transactions are collectively referred to as the "Reorganization"). 
     The Reorganization, which does not require shareholder approval, is expected to take place on or about November 14, 2025. The Reorganization is expected to be a tax-free transaction. This means that neither Fidelity Advisor &#xae; Technology Fund nor its shareholders will recognize any gain or loss as a direct result of the Reorganization. 
     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.

     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. 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 securities of companies principally engaged in the utilities industry and companies deriving a majority of their revenues from their utility operations. 
          
        
      
     These companies may include, for example, companies that produce electricity, including nuclear and non-nuclear facilities; companies that distribute and transmit natural and manufactured gas; water treatment and other utility companies; companies that operate as independent power producers, gas and power marketing and trading specialists and/or integrated energy merchants; and companies that engage in the generation and distribution of electricity using renewable sources. 
     Fidelity may consider a company to be principally engaged in the designated business activity or activities based on: (i) the level of a company's assets, income, sales, or profits that are committed to, derived from, or related to the designated business activity or activities, or (ii) whether a third party has given the company an industry or sector classification consistent with the designated business activity or activities. Whether a company is principally engaged in the designated business activity or activities can be determined under any of these factors. 
     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.

     Proposed Reorganization. The Board of Trustees of Fidelity Advisor Series VII has unanimously approved an Agreement and Plan of Reorganization ("Agreement") between Fidelity Advisor &#xae; Utilities Fund and Utilities Portfolio pursuant to which Fidelity Advisor &#xae; Utilities Fund would be reorganized on a tax-free basis with and into Utilities Portfolio. 
      
       As a result of the proposed Reorganization, shareholders of Fidelity Advisor &#xae; Utilities Fund would receive, respectively, corresponding shares of Utilities Portfolio. 
     The Agreement provides for the transfer of all of the assets of Fidelity Advisor &#xae; Utilities Fund in exchange for corresponding shares of Utilities Portfolio equal in value to the net assets of Fidelity Advisor &#xae; Utilities Fund and the assumption by Utilities Portfolio of all of the liabilities of Fidelity Advisor &#xae; Utilities Fund. After the exchange, Fidelity Advisor &#xae; Utilities Fund will distribute the Utilities Portfolio shares to its shareholders pro rata, in liquidation of Fidelity Advisor &#xae; Utilities Fund. As a result, shareholders of Fidelity Advisor &#xae; Utilities Fund will become shareholders of Utilities Portfolio (these transactions are collectively referred to as the "Reorganization"). 
     The Reorganization, which does not require shareholder approval, is expected to take place on or about October 17, 2025. The Reorganization is expected to be a tax-free transaction. This means that neither Fidelity Advisor &#xae; Utilities Fund nor its shareholders will recognize any gain or loss as a direct result of the Reorganization. 
     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.

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.
