The following information replaces similar information found in the “Fund Management” section under the “Advisory Fee(s)” heading

Each class of the fund pays a management fee to the Adviser.

The management fee is calculated and paid to the Adviser every month.

When determining a class’s management fee, a mandate rate is calculated based on the monthly average net assets of a group of funds advised by FMR within a designated asset class. A discount rate is subtracted from the mandate rate once the fund’s monthly average net assets reach a certain level. The mandate rate and discount rate may vary by class.

The annual management fee rate for each class of shares of the fund offered through this prospectus is the lesser of (1) the class’s mandate rate reduced by the class’s discount rate (if applicable) or (2) 0.72% for Class A, 0.72% for Class M, 0.71% for Class C, 0.69% for Class I, and 0.56% for Class Z. One‑twelfth of the management fee rate for a class is applied to the average net assets of the class for the month, giving a dollar amount which is the management fee for the class for that month.

A different management fee rate may be applicable to each class of the fund. The difference between classes is the result of separate arrangements for class-level services and/or waivers of certain expenses. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund’s assets, which do not vary by class.

The annual management fee rate for the class of shares of each fund offered through this prospectus is the lesser of (1) the class’s mandate rate reduced by the class’s discount rate (if applicable) or (2) 0.72% for Fidelity^® Environment and Alternative Energy Fund and 0.71% for Fidelity^® Natural Resources Fund. One‑twelfth of the management fee rate for a class is applied to the average net assets of the class for the month, giving a dollar amount which is the management fee for the class for that month.

A different management fee rate may be applicable to each class of a fund. The difference between classes is the result of separate arrangements for class-level services and/or waivers of certain expenses. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of a fund’s assets, which do not vary by class.

The following information replaces similar information found in the “Fund Management” section under the “Advisory Fee(s)” heading.

Each class of each fund pays a management fee to the Adviser.

The management fee is calculated and paid to the Adviser every month.

When determining a class’s management fee, a mandate rate is calculated based on the monthly average net assets of a group of funds advised by FMR within a designated asset class. A discount rate is subtracted from the mandate rate once a fund’s monthly average net assets reach a certain level. The mandate rate and discount rate may vary by class.

The annual management fee rate for the class of shares of each fund offered through this prospectus is the lesser of (1) the class’s mandate rate reduced by the class’s discount rate (if applicable) or (2) the amount listed below:

Fund	Retail Class
Biotechnology Portfolio	0.67%
Health Care Portfolio	0.65%
Health Care Services Portfolio	0.69%
Medical Technology and Devices Portfolio	0.66%
Pharmaceuticals Portfolio	0.70%

One‑twelfth of the management fee rate for a class is applied to the average net assets of the class for the month, giving a dollar amount which is the management fee for the class for that month.

A different management fee rate may be applicable to each class of a fund. The difference between classes is the result of separate arrangements for class-level services and/or waivers of certain expenses. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of a fund’s assets, which do not vary by class.

The following information replaces similar information found in the “Fund Management” section under the “Advisory Fee(s)” heading.

Each class of the fund pays a management fee to the Adviser.

The management fee is calculated and paid to the Adviser every month.

The management fee is determined by calculating a basic fee and then applying a performance adjustment.

When determining a class’s basic fee, a mandate rate is calculated based on the monthly average net assets of a group of funds advised by FMR within a designated asset class. A discount rate is subtracted from the mandate rate once the fund’s monthly average net assets reach a certain level. The mandate rate and discount rate may vary by class.

The annual basic fee rate for the class of shares of the fund offered through this prospectus is the lesser of (1) the class’s mandate rate reduced by the class’s discount rate (if applicable) or (2) 0.57%. One‑twelfth of the basic fee rate for a class is applied to the average net assets of the class for the month, giving a dollar amount which is the basic fee for the class for that month.

The performance adjustment rate is calculated monthly by comparing over the performance period the fund’s performance to that of the performance adjustment index listed below.

Fund	Performance Adjustment Index
Fidelity® Telecom and Utilities Fund	Russell 3000® Telecom and Utilities Select Index

The performance period is the most recent 36 month period.

The maximum annualized performance adjustment rate is ±0.15% of the fund’s average net assets over the performance period. The performance adjustment rate is divided by twelve and multiplied by the fund’s average net assets over the performance period, and the resulting dollar amount is then proportionately added to or subtracted from a class’s basic fee.

A different management fee rate may be applicable to each class of the fund. The difference between classes is the result of separate arrangements for class-level services and/or waivers of certain expenses. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund’s assets, which do not vary by class.

STATEMENT OF ADDITIONAL INFORMATION

Effective March 1, 2024, the fund’s management contract was amended to incorporate administrative services previously covered under separate services agreements. The amended contract incorporates a management fee rate that may vary by class. The Adviser or an affiliate pays certain expenses of managing and operating the fund out of each class’s management fee.

The following information replaces similar information found in the “Management Contract” section.

Management-Related Expenses. In addition to the management fee payable to FMR, and the costs associated with securities lending, as applicable, the fund or each class thereof, as applicable, pays all of its expenses that are not assumed by those parties. The fund pays for the typesetting, printing, and mailing of its proxy materials to shareholders, legal expenses, and the fees of the custodian, auditor, and Independent Trustees. Other expenses paid by the fund include interest, taxes, brokerage commissions, fees and expenses associated with the fund’s securities lending program, if applicable, the fund’s proportionate share of insurance premiums and Investment Company Institute dues, and the costs of registering shares under federal securities laws and making necessary filings under state securities laws. The fund is also liable for such non-recurring expenses as may arise, including costs of any litigation to which the fund may be a party, and any obligation it may have to indemnify its officers and Trustees with respect to litigation.

Management Fee.

For the services of FMR under the fund’s management contract, each class of the fund pays FMR a monthly management fee.

For the fund, a mandate rate is calculated based on the monthly average net assets of a group of funds advised by FMR within a designated asset class. This rate may vary by share class.

The mandate rate is calculated on a cumulative basis pursuant to the following schedule:

MANDATE RATE SCHEDULE

Average Designated Asset Class Assets	Class A, Class M, Class C, and Class I Annualized Rate	Class Z Annualized Rate
First $400 billion	0.920%	0.800%
Next $400 billion	0.860%	0.730%
Next $400 billion	0.830%	0.700%
Over $1,200 billion	0.810%	0.690%

For the fund, a discount percentage is calculated based on the monthly average net assets of a broader group of funds advised by FMR representing multiple asset classes and the monthly average net assets of the fund. After determination of the applicable tier bound level in the following schedule, the discount percentage for the fund is calculated on a cumulative basis pursuant to the schedule. For the fund, the discount rate for a class is the class’s mandate rate multiplied by the discount percentage.

DISCOUNT PERCENTAGE SCHEDULE

Average Group Assets  Tier Bounds		% Discount for Average Incremental Fund Assets

2.8	<3.1	0%	9.0%	11.0%	12.5%
3.1	Above 3.1	0%	10.0%	12.0%	13.5%

The annual management fee rate for each class of shares of the fund offered through this SAI is the lesser of (1) the class’s mandate rate reduced by the class’s discount rate or (2) the amount set forth in the following table:

Fund/Class	Maximum Management Fee    Rate
Fidelity® International  Real Estate Fund/  Class A	0.88%

Fidelity® International  Real Estate Fund/  Class C	0.88%
Fidelity® International  Real Estate Fund/  Class I	0.84%
Fidelity® International  Real Estate Fund/  Class Z	0.72%

One-twelfth of the management fee rate is applied to the class’s average net assets for the month, giving a dollar amount which is the management fee for the class for that month.

A different management fee rate may be applicable to each class of the fund. The difference between classes is the result of separate arrangements for class-level services and/or waivers of certain expenses. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund’s assets, which do not vary by class.

TRANSFER AND SERVICE AGENT SERVICES

Fidelity Investments Institutional Operations Company LLC (FIIOC), an affiliate of FMR, which is located at 245 Summer Street, Boston, Massachusetts 02210 (or an agent, including an affiliate), performs transfer agency services under the terms of the fund’s management contract.

Prior to March 1, 2024, the fund or class, as applicable, bore the cost of transfer agency services under a separate agreement covering such services.

FIIOC may collect fees charged in connection with providing certain types of services such as exchanges, closing out fund balances, checkwriting, wire transactions, and providing historical account research, as applicable.

FIIOC bears the expense of typesetting, printing, and mailing prospectuses, statements of additional information, and all other reports, notices, and statements to existing shareholders, with the exception of proxy statements.

Fund shares may be owned by intermediaries for the benefit of their customers. In those instances, a fund may not maintain an account for shareholders, and some or all of the recordkeeping and/or administrative services for these accounts may be performed by intermediaries. FIIOC or an affiliate may make payments out of its own resources to intermediaries (including affiliates of FIIOC) for recordkeeping services.

Retirement plans may also hold fund shares in the name of the plan or its trustee, rather than the plan participant. In situations where FIIOC or an affiliate does not provide recordkeeping services, plan recordkeepers, who may have affiliated financial intermediaries who sell shares of the fund, may, upon direction, be paid for providing recordkeeping services to plan participants. Payments may also be made, upon direction, for other plan expenses. FIIOC may also pay an affiliate for providing services that otherwise would have been performed by FIIOC.

FIIOC or an affiliate may make networking payments out of its own resources to intermediaries who perform transactions for the fund through the National Securities Clearing Corporation (NSCC). NSCC, a wholly owned subsidiary of The Depository Trust & Clearing Corporation, provides centralized clearance, settlement, and information services for mutual funds and other financial services companies.

Fidelity Service Company, Inc. (FSC), an affiliate of FMR (or an agent, including an affiliate), calculates the NAV and dividends for shares, maintains the fund’s portfolio and general accounting records, and administers the fund’s securities lending program under the terms of the fund’s management contract.

Prior to March 1, 2024, the fund bore the cost of pricing and bookkeeping services under a separate agreement covering such services.

Effective March 1, 2024, the fund’s sub-advisory agreements with FMR Investment Management (UK) Limited, Fidelity Management & Research (Hong Kong) Limited, and Fidelity Management & Research (Japan) Limited were amended. The following information supplements similar information found in the “Management Contract” section.

Under the terms of the sub-advisory agreements, FMR pays each sub-adviser monthly fees equal to 110% of the sub-adviser’s costs for providing sub-advisory services.

Effective March 1, 2024, the fund’s sub-advisory agreement with FIL Investment Advisors (FIA) was amended. The following information replaces similar information found in the “Management Contract” section.

FMR, and not the fund, pays FIA. Under the terms of the sub-advisory agreement, FMR pays FIA monthly fees at an annual rate of 0.44% with respect to the average daily net assets of the fund managed by FIA. FIA in turn pays FIA(UK).

Sustainable Proxy Voting Guidelines – Shareholder Proposals on Natural and Human Capital Issues

January 2024

I. INTRODUCTION

These guidelines are intended to help Fidelity’s customers and the companies in which Fidelity invests understand how the team of investment professionals supporting Fidelity’s sustainable investing strategies (the “sustainable investing team” or “we”) consider, evaluate, and generally vote, on natural and human capital issues that our research has determined are financially material.

For companies held by Fidelity’s sustainable investing strategies, including Fidelity funds listed on Exhibit 1, as amended from time to time (“Sustainable Funds”), shareholder proposals related to natural and human capital topics that generally would be voted in accordance with Section V of the Fidelity Proxy Voting Guidelines¹ will be voted instead in accordance with these sustainable guidelines, which augment Section V of the Fidelity Proxy Voting Guidelines. All other proposals for companies held by the Sustainable Funds other than those covered by Section V will continue to be voted in accordance with the Fidelity Proxy Voting Guidelines.

For proposals related to topics not specifically addressed by these guidelines and the principles outlined below, Fidelity starts from the same four-point decision-making framework outlined in Section V of

the Fidelity Proxy Voting Guidelines and applies it through the lens of the Sustainable Funds’ investment objectives and strategies, which benefit from additional transparency and action on sustainability factors. Under the framework, Fidelity will first and foremost consider whether the proposal addresses a topic that our proprietary research has identified as financially material for the company in question. If the financial materiality threshold is met, we will consider the other elements of the framework, namely whether the proposal would provide valuable information to the business or to investors; whether it would improve transparency without being overly prescriptive; and whether compliance with the proposal is realistic or practical for the company. Importantly, we may evaluate certain elements of the framework (e.g., whether the proposal provides valuable information) differently for the Fidelity Sustainable Funds than for other funds Fidelity manages.

II. TRANSPARENCY PRINCIPLES

Fidelity believes that transparency is critical to sound corporate governance. Transparency allows investors to better engage with companies with the goal of creating value for the company and shareholders while mitigating potential risks. In evaluating natural and human capital shareholder proposals for the Sustainable Funds, we begin from Fidelity’s overarching approach to stewardship (as outlined in the Stewardship Principles²) and apply the additional voting principles outlined below. On each topic, our goal is to ensure a complete understanding of a company’s oversight, process, and progress. To that end, for each topic, we expect companies to share a description of the management and relevant governance process(es), or policies and share relevant data to improve transparency. Where appropriate, we also encourage target or goal setting that allows companies and investors to track progress on the topic more effectively.

III. NATURAL CAPITAL

Companies that deploy natural resources efficiently and consider the effects of the environment on their assets (including physical assets) are better positioned to deliver value now and in the future.

Climate.

To better assess a company’s climate-related risks and opportunities we expect companies to:

• Management: Describe specific strategic initiatives and capital allocation priorities supporting any reduction targets adopted as well as the company’s climate governance, oversight, and risk-management processes. Additionally, we expect companies to describe the potential risks and opportunities of various possible transition pathways (i.e., orderly, disorderly, status quo), including incorporating carbon pricing considerations and impact on business decisions.

• Transparency: Disclose Scope 1, 2 and, where appropriate and available, material Scope 3 greenhouse gas (GHG) emissions using commonly accepted and consistent methodologies (e.g., the GHG Protocol); and, where material and feasible to the company, disclose direct measurement and industry equivalent calculation of intensity data, avoided emissions, and financed emissions information.

Where appropriate, we encourage companies to:

• Targets: Set near-, medium-, and long-term reduction targets that are aligned with the business’s objectives. We prefer targets that are rigorous, science-based if available for the company’s sector, and which demonstrate alignment to global goals.

Natural Resources.

To better assess a company’s natural resources-related risks and opportunities, we expect companies to:

• Management: Publish a description of the governance and oversight of financially material issues related to natural resource management and implement initiatives to limit or mitigate natural resource impacts.

• Transparency: Provide quantitative disclosure of material impacts to natural resources (i.e., water usage, deforestation, biodiversity) effected through normal business operations, and mitigation plans to reduce those impacts.

Where appropriate, we encourage companies to:

• Targets: Establish quantitative, timebound targets (e.g., water intensity, biodiversity loss) to enable investors to assess the company’s risk management and mitigation efforts.

Raw Materials & Waste.

To better assess a company’s exposure to risks and opportunities related to raw materials and waste, we expect companies to:

• Management: Adopt supply chain management policies and governance structures that account for raw materials, describing relevant risks and oversight of those risks. Where feasible, we encourage companies to design processes and products that minimize waste to landfill.

• Transparency: Provide quantitative disclosure on the use of raw materials, as well as waste generated by the company (i.e., volume of plastic waste, waste to landfill, percentage of raw materials certified to a sustainability standard).

Where appropriate, we encourage companies to:

• Targets: Set goals or objectives for improvement of the reported metrics and strategies to achieve those goals.

IV. HUMAN CAPITAL

No business can succeed over the long term without the support of employees, customers, suppliers, and the communities in which it operates. We find issuers that carefully manage and invest in these key relationships build lasting resilience and competitive advantage.

Workforce & Talent Management.

To better assess a company’s workforce related risks and opportunities we expect companies to (where, and to the extent, permitted by law):

• Management: Publish a description of the oversight and/or governance processes for workforce related policies and procedures, including whistleblower, ethics, discrimination, and harassment policies.

• Transparency: Publish: a) an adjusted pay gap analysis that includes all components of compensation (base, bonus and equity), evaluated at both a gender and racial level and b) an unadjusted pay gap analysis (which includes all components of compensation), defined as the average difference in pay between all genders and racial groups within a company; c) data showing the total number of employees, by race/ethnicity and gender, the number of employees in each job category, by race/ethnicity and gender, and the number of

employees in each company location or major region of operation, by race/ethnicity and gender; d) total compensation and benefits costs by employee category; e) the total number of employees who have voluntarily left the company in a given period of time and their demographics.

Where appropriate, we encourage companies to:

• Targets: Set goals or objectives for improvement of the reported metrics and strategies to achieve those goals.

Human Rights.

To better assess a company’s human-rights related risks and opportunities we expect companies to:

• Management: Adopt a Supply Chain Code of Conduct (the “Code”) that is aligned with the United Nations Universal Declaration of Human Rights³ and United Nations Guiding Principles on Business and Human Rights (UNGP) and describe the governance or accountability mechanism for enforcement of the Code or explaining why that may not be appropriate for their business.

• Transparency: Consider whether, and how frequently, suppliers are audited for compliance with the company’s Code and the proportion of the supply chain – Tier 1, 2, and 3 where relevant – that is annually audited, along with summary findings and corrective actions taken by the company.

Where appropriate, we encourage companies to:

• Targets: Set goals or objectives for improvement of the reported metrics and strategies to achieve those goals.

STATEMENT OF ADDITIONAL INFORMATION

Effective March 1, 2024, each fund’s management contract was amended to incorporate administrative services previously covered under separate services agreements. Each amended contract incorporates a management fee rate that may vary by class. The Adviser or an affiliate pays certain expenses of managing and operating each fund out of each class’s management fee.

The following information replaces similar information found in the “Management Contracts” section.

Management-Related Expenses. In addition to the management fee payable to FMR, and the costs associated with securities lending, as applicable, a fund or each class thereof, as applicable, pays all of its expenses that are not assumed by those parties. A fund pays for the typesetting, printing, and mailing of its proxy materials to shareholders, legal expenses, and the fees of the custodian, auditor, and Independent Trustees. Other expenses paid by a fund include interest, taxes, brokerage commissions, fees and expenses associated with the fund’s securities lending program, if applicable, the fund’s proportionate share of insurance premiums and Investment Company Institute dues, and the costs of registering shares under federal securities laws and making necessary filings under state securities laws. A fund is also liable for such non-recurring expenses as may arise, including costs of any litigation to which the fund may be a party, and any obligation it may have to indemnify its officers and Trustees with respect to litigation.

Management Fees.

For the services of FMR under each fund’s management contract, each class of each fund pays FMR a monthly management fee.

For each fund, a mandate rate is calculated based on the monthly average net assets of a group of funds advised by FMR within a designated asset class. This rate may vary by share class.

For each fund, the mandate rate is calculated on a cumulative basis pursuant to the following schedule:

MANDATE RATE SCHEDULE

Average Designated Asset Class Assets	Class A, Class M, Class C, and Class I Annualized Rate	Class Z Annualized Rate
First $400 billion	0.770%	0.650%
Next $400 billion	0.710%	0.580%
Next $400 billion	0.680%	0.550%
Over $1,200 billion	0.660%	0.540%

For each fund, a discount percentage is calculated based on the monthly average net assets of a broader group of funds advised by FMR representing multiple asset classes and the monthly average net assets of the fund. After determination of the applicable tier bound level in the following schedule, the discount percentage for each fund is calculated on a cumulative basis pursuant to the schedule. For each fund, the discount rate for a class is the class’s mandate rate multiplied by the discount percentage.

DISCOUNT PERCENTAGE SCHEDULE

Average Group Assets  Tier Bounds		% Discount for Average Incremental Fund Assets
Lower	Upper	First   $1B	Next $19B	Next $10B	Over $30B
0	<$1 trillion	0%	3.0%	5.0%	6.5%

2.8	<3.1	0%	9.0%	11.0%	12.5%
3.1	Above 3.1	0%	10.0%	12.0%	13.5%

The annual management fee rate for each class of shares of each fund offered through this SAI is the lesser of (1) the class’s mandate rate reduced by the class’s discount rate or (2) the amount set forth in the following table:

Fund/Class	Maximum Management Fee    Rate
Communication Services  Portfolio/Class A	0.72%
Communication Services  Portfolio/Class M	0.72%

Telecommunications  Portfolio/Class M	0.72%
Telecommunications  Portfolio/Class C	0.72%
Telecommunications  Portfolio/Class I	0.67%
Telecommunications  Portfolio/Class Z	0.56%

One-twelfth of the management fee rate is applied to the class’s average net assets for the month, giving a dollar amount which is the management fee for the class for that month.

A different management fee rate may be applicable to each class of a fund. The difference between classes is the result of separate arrangements for class-level services and/or waivers of certain expenses. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of a fund’s assets, which do not vary by class.

Prior to March 1, 2024, each fund or class, as applicable, bore the cost of transfer agency services under a separate agreement covering such services.

FIIOC may collect fees charged in connection with providing certain types of services such as exchanges, closing out fund balances, checkwriting, wire transactions, and providing historical account research, as applicable.

FIIOC bears the expense of typesetting, printing, and mailing prospectuses, statements of additional information, and all other reports, notices, and statements to existing shareholders, with the exception of proxy statements.

Fund shares may be owned by intermediaries for the benefit of their customers. In those instances, a fund may not maintain an account for shareholders, and some or all of the recordkeeping and/or administrative services for these accounts may be performed by intermediaries. FIIOC or an affiliate may make payments out of its own resources to intermediaries (including affiliates of FIIOC) for recordkeeping services.

Retirement plans may also hold fund shares in the name of the plan or its trustee, rather than the plan participant. In situations where FIIOC or an affiliate does not provide recordkeeping services, plan recordkeepers, who may have affiliated financial intermediaries who sell shares of the funds, may, upon direction, be paid for providing recordkeeping services to plan participants. Payments may also be made, upon direction, for other plan expenses. FIIOC may also pay an affiliate for providing services that otherwise would have been performed by FIIOC.

FIIOC or an affiliate may make networking payments out of its own resources to intermediaries who perform transactions for the funds through the National Securities Clearing Corporation (NSCC).

STATEMENT OF ADDITIONAL INFORMATION

Effective March 1, 2024, the fund’s management contract was amended to incorporate administrative services previously covered under separate services agreements. The amended contract incorporates a management fee rate that may vary by class. The Adviser or an affiliate pays certain expenses of managing and operating the fund out of each class’s management fee.

The following information replaces similar information found in the “Management Contract” section.

Management-Related Expenses. In addition to the management fee payable to FMR, and the costs associated with securities lending, as applicable, the fund or each class thereof, as applicable, pays all of its expenses that are not assumed by those parties. The fund pays for the typesetting, printing, and mailing of its proxy materials to shareholders, legal expenses, and the fees of the custodian, auditor, and Independent Trustees. Other expenses paid by the fund include interest, taxes, brokerage commissions, fees and expenses associated with the fund’s securities lending program, if applicable, the fund’s proportionate share of insurance premiums and Investment Company Institute dues, and the costs of registering shares under federal securities laws and making necessary filings under state securities laws. The fund is also liable for such non-recurring expenses as may arise, including costs of any litigation to which the fund may be a party, and any obligation it may have to indemnify its officers and Trustees with respect to litigation.

Management Fee.

For the services of FMR under the fund’s management contract, each class of the fund pays FMR a monthly management fee.

For the fund, a mandate rate is calculated based on the monthly average net assets of a group of funds advised by FMR within a designated asset class. This rate may vary by share class.

The mandate rate is calculated on a cumulative basis pursuant to the following schedule:

MANDATE RATE SCHEDULE

Average Designated Asset Class Assets	Retail Class Annualized Rate
First $400 billion	0.900%
Next $400 billion	0.820%
Next $400 billion	0.770%
Over $1,200 billion	0.730%

For the fund, a discount percentage is calculated based on the monthly average net assets of a broader group of funds advised by FMR representing multiple asset classes and the monthly average net assets of the fund. After determination of the applicable tier bound level in the following schedule, the discount percentage for the fund is calculated on a cumulative basis pursuant to the schedule. For the fund, the discount rate for a class is the class’s mandate rate multiplied by the discount percentage.

DISCOUNT PERCENTAGE SCHEDULE

Average Group Assets  Tier Bounds		% Discount for Average Incremental Fund Assets
Lower	Upper	First   $1B	Next $19B	Next $10B	Over $30B
0	<$1 trillion	0%	3.0%	5.0%	6.5%

2.8	<3.1	0%	9.0%	11.0%	12.5%
3.1	Above 3.1	0%	10.0%	12.0%	13.5%

The annual management fee rate for the class of shares of the fund offered through this SAI is the lesser of (1) the class’s mandate rate reduced by the class’s discount rate or (2) the amount set forth in the following table:

Fund/Class	Maximum Management Fee    Rate
Fidelity® International  Real Estate Fund/ Fidelity® International  Real Estate Fund	0.88%

One-twelfth of the management fee rate is applied to the class’s average net assets for the month, giving a dollar amount which is the management fee for the class for that month.

A different management fee rate may be applicable to each class of the fund. The difference between classes is the result of separate arrangements for class-level services and/or waivers of certain expenses. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund’s assets, which do not vary by class.

Effective March 1, 2024, the fund’s management contract was amended to incorporate administrative services previously covered under separate services agreements. The amended contract incorporates a basic fee rate that may vary by class (subject to a performance adjustment). The Adviser or an affiliate pays certain expenses of managing and operating the fund out of each class’s management fee.

The following information replaces similar information found in the “Management Contract” section.

Management-Related Expenses. In addition to the management fee payable to FMR, and the costs associated with securities lending, as applicable, the fund pays all of its expenses that are not assumed by those parties. The fund pays for the typesetting, printing, and mailing of its proxy materials to shareholders, legal expenses, and the fees of the custodian, auditor, and Independent Trustees. Other expenses paid by the fund include interest, taxes, brokerage commissions, fees and expenses associated with the fund’s securities lending program, if applicable, the fund’s proportionate share of insurance premiums and Investment Company Institute dues, and the costs of registering shares under federal securities laws and making necessary filings under state securities laws. The fund is also liable for such non-recurring expenses as may arise, including costs of any litigation to which the fund may be a party, and any obligation it may have to indemnify its officers and Trustees with respect to litigation.

Management Fee.

For the services of FMR under the fund’s management contract, each class of the fund pays FMR a monthly management fee. The management fee has two components: (i) a basic fee and (ii) a performance adjustment.

Computing the Basic Fee.

For the fund, a mandate rate is calculated based on the monthly average net assets of a group of funds advised by FMR within a designated asset class. This rate may vary by share class.

The mandate rate is calculated on a cumulative basis pursuant to the following schedule:

MANDATE RATE SCHEDULE

Average Designated Asset Class Assets	Retail Class Annualized Rate
First $400 billion	0.750%
Next $400 billion	0.670%
Next $400 billion	0.610%
Over $1,200 billion	0.580%

For the fund, a discount percentage is calculated based on the monthly average net assets of a broader group of funds advised by FMR representing multiple asset classes and the monthly average net assets of the fund. After determination of the applicable tier bound level in the following schedule, the discount percentage for a fund is calculated on a cumulative basis pursuant to the schedule. For the fund, the discount rate for a class is the class’s mandate rate multiplied by the discount percentage.

DISCOUNT PERCENTAGE SCHEDULE

Average Group Assets  Tier Bounds		% Discount for Average Incremental Fund Assets
Lower	Upper	First   $1B	Next $19B	Next $10B	Over $30B
0	<$1 trillion	0%	3.0%	5.0%	6.5%
1	<1.5	0%	4.0%	6.0%	7.5%
1.5	<1.9	0%	5.0%	7.0%	8.5%
1.9	<2.2	0%	6.0%	8.0%	9.5%
2.2	<2.5	0%	7.0%	9.0%	10.5%
2.5	<2.8	0%	8.0%	10.0%	11.5%
2.8	<3.1	0%	9.0%	11.0%	12.5%
3.1	Above 3.1	0%	10.0%	12.0%	13.5%

The annual basic fee rate for the class of shares of a fund offered through this SAI is the lesser of (1) the class’s mandate rate reduced by the class’s discount rate or (2) the amount set forth in the following table:

Fund/Class	Maximum Basic Fee  Rate
Fidelity® Telecom and  Utilities Fund/ Fidelity®  Telecom and Utilities Fund	0.57%

One-twelfth of the basic fee rate is applied to the class’s average net assets for the month, giving a dollar amount which is the basic fee for the class for that month.

Computing the Performance Adjustment. The basic fee for the following fund is subject to upward or downward adjustment, depending upon whether, and to what extent, the fund’s investment performance for the performance period exceeds, or is exceeded by, the record of the designated index over the same period. The performance period consists of the most recent month plus the previous 35 months. The performance comparison is made at the end of each month.

Fund	Performance Adjustment Index
Fidelity® Telecom and Utilities Fund	Russell 3000® Telecom and Utilities Select Index

For the period prior to September 21, 2020, Fidelity^® Telecom and Utilities Fund compares its performance to the Russell 3000^® Utilities Index (Prior Index). For the period beginning September 21, 2020, Fidelity^® Telecom and Utilities Fund compares its performance to Russell 3000^® Telecom and Utilities Select Index (Current Index). Because the performance adjustment is based on a rolling 36 month measurement period, during a transition period the fund’s performance will be compared to a 36 month blended index return that reflects the performance of the Current Index for the portion of the 36 month performance measurement period beginning on the date of the index change and the performance of the Prior Index for the remainder of the measurement period. At the conclusion of the transition period, the performance of the Prior Index will be eliminated from the performance adjustment calculation, and the calculation will include only the performance of the Current Index.

Russell 3000^® Utilities Index is a market capitalization-weighted index of utility stocks in the Russell 3000^® Index.

Russell 3000^® Telecom and Utilities Select Index is a market capitalization-weighted index of telecom and utility stocks that are included in the Russell 3000^® Index and is intended to continue the performance of the existing Russell 3000^® Utilities Index. Industries in the index include the Russell 3000^® Index constituents in the

ICB Subsectors: Telecommunications Services, Alternative Electricity, Conventional Electricity, Multi-Utilities, Gas Distribution, and Water.

For Fidelity^® Telecom and Utilities Fund, each percentage point of difference, calculated to the nearest 0.01% (up to a maximum difference of ±7.50), is multiplied by a performance adjustment rate of 0.02%. The maximum annualized performance adjustment rate is ±0.15% of the fund’s average net assets over the performance period.

One twelfth (1/12) of this rate is then applied to the fund’s average net assets over the performance period, giving a dollar amount which will be proportionately added to (or subtracted from) a class’s basic fee.

The performance of a fund or class, as applicable, is calculated based on change in NAV. For purposes of calculating the performance adjustment, any dividends or capital gain distributions paid by the fund or class are treated as if reinvested in that fund’s or class’s shares at the NAV as of the record date for payment.

The record of an index is based on change in value and is adjusted for any cash distributions from the companies whose securities compose the index. Because the adjustment to the basic fee is based on the fund’s performance compared to the investment record of the index, the controlling factor is not whether the fund’s performance is up or down per se, but whether it is up or down more or less than the record of the designated performance adjustment index. Moreover, the comparative investment performance of the fund is based solely on the relevant performance period without regard to the cumulative performance over a longer or shorter period of time.

A different management fee rate may be applicable to each class of the fund. The difference between classes is the result of separate arrangements for class-level services and/or waivers of certain expenses. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund’s assets, which do not vary by class.

The following information replaces similar information found in the “Transfer and Service Agent Agreements” section.

TRANSFER AND SERVICE AGENT SERVICES

Fidelity Investments Institutional Operations Company LLC (FIIOC), an affiliate of FMR, which is located at 245 Summer Street, Boston, Massachusetts 02210 (or an agent, including an affiliate), performs transfer agency services under the terms of the fund’s management contract.

Prior to March 1, 2024, the fund or class, as applicable, bore the cost of transfer agency services under a separate agreement covering such services.

FIIOC may collect fees charged in connection with providing certain types of services such as exchanges, closing out fund balances, checkwriting, wire transactions, and providing historical account research, as applicable.

FIIOC bears the expense of typesetting, printing, and mailing prospectuses, statements of additional information, and all other reports, notices, and statements to existing shareholders, with the exception of proxy statements.

Fund shares may be owned by intermediaries for the benefit of their customers. In those instances, a fund may not maintain an account for shareholders, and some or all of the recordkeeping services for these accounts may be performed by third parties. FIIOC or an affiliate may make payments to intermediaries (including affiliates of FIIOC) for recordkeeping and other services.

Retirement plans may also hold fund shares in the name of the plan or its trustee, rather than the plan participant. In situations where FIIOC or an affiliate does not provide recordkeeping services, plan recordkeepers, who may have affiliated financial intermediaries who sell shares of the fund, may, upon direction, be paid for providing recordkeeping services to plan participants. Payments may also be made, upon direction, for other plan expenses. FIIOC may also pay an affiliate for providing services that otherwise would have been performed by FIIOC.

In certain situations where FIIOC or an affiliate provides recordkeeping services to a retirement plan, payments may be made to pay for plan expenses. The amount of such payments may be based on investments in particular Fidelity^® funds, or may be fixed for a given period of time. Upon direction, payments may be made to plan sponsors, or at the direction of plan sponsors, third parties, for expenses incurred in connection with the plan. FIIOC may also pay an affiliate for providing services that otherwise would have been performed by FIIOC.

Fidelity Service Company, Inc. (FSC), an affiliate of FMR (or an agent, including an affiliate) calculates the NAV and dividends for shares, maintains the fund’s portfolio and general accounting records, and administers the fund’s securities lending program under the terms of the fund’s management contract.

Prior to March 1, 2024, the fund bore the cost of pricing and bookkeeping services under a separate agreement covering such services.

Effective March 1, 2024, the fund’s sub-advisory agreements with FMR Investment Management (UK) Limited, Fidelity Management & Research (Hong Kong) Limited, and Fidelity Management & Research (Japan) Limited were amended. The following information supplements similar information found in the “Management Contract” section.

Under the terms of the sub-advisory agreements, FMR pays each sub-adviser monthly fees equal to 110% of the sub-adviser’s costs for providing sub-advisory services.
