For the period ended February 28, 2026
1. Organization.
Fidelity Maryland Municipal Income Fund (the Fund) is a non-diversified fund of Fidelity Union Street Trust (the Trust) and is authorized to issue an unlimited number of shares. Share transactions on the Statement of Changes in Net Assets may contain exchanges between affiliated funds. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund may be affected by economic and political developments in the state of Maryland.
2. Investments in Fidelity Central Funds.
Funds may invest in Fidelity Central Funds, which are open-end investment companies generally available only to other investment companies and accounts managed by the investment adviser and its affiliates. The Schedule of Investments lists any Fidelity Central Funds held as an investment as of period end, but does not include the underlying holdings of each Fidelity Central Fund. An investing fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.
Based on its investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the investing fund. These strategies are consistent with the investment objectives of the investing fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity Central Funds and thus a decline in the value of the investing fund.

A Expenses expressed as a percentage of average net assets and are as of each underlying Central Fund's most recent annual or semi-annual shareholder report.
A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds which contain the significant accounting policies (including investment valuation policies) of those funds, and are not covered by the Report of Independent Registered Public Accounting Firm, are available on the Securities and Exchange Commission website or upon request.
3. Significant Accounting Policies.
The Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services - Investment Companies. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. The Fund operates as a single operating segment. The Fund's income, expenses, assets, and performance are regularly monitored and assessed as a whole by the investment adviser and other individuals responsible for oversight functions of the Trust, using the information presented in the financial statements and financial highlights. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The Fund's Schedule of Investments lists any underlying mutual funds or exchange-traded funds but does not include the underlying holdings of these funds. The following summarizes the significant accounting policies of the Fund:
Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Board of Trustees (the Board) has designated the Fund's investment adviser as the valuation designee responsible for the fair valuation function and performing fair value determinations as needed. The investment adviser has established a Fair Value Committee (the Committee) to carry out the day-to-day fair valuation responsibilities and has adopted policies and procedures to govern the fair valuation process and the activities of the Committee. In accordance with these fair valuation policies and procedures, which have been approved by the Board, the Fund attempts to obtain prices from one or more third party pricing services or brokers to value its investments. When current market prices, quotations or currency exchange rates are not readily available or reliable, investments will be fair valued in good faith by the Committee, in accordance with the policies and procedures. Factors used in determining fair value vary by investment type and may include market or investment specific events, transaction data, estimated cash flows, and market observations of comparable investments. The frequency that the fair valuation procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee manages the Fund's fair valuation practices and maintains the fair valuation policies and procedures. The Fund's investment adviser reports to the Board information regarding the fair valuation process and related material matters.
The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:
Level 1 - unadjusted quoted prices in active markets for identical investments
Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)
Valuation techniques used to value the Fund's investments by major category are as follows:
Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing services or from brokers who make markets in such securities. Municipal securities are valued by pricing services who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing services. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.
Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.
Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level as of February 28, 2026 is included at the end of the Fund's Schedule of Investments.
Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Debt obligations may be placed on non-accrual status and related interest income may be reduced by ceasing current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured.
Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expenses included in the accompanying financial statements reflect the expenses of that fund and do not include any expenses associated with any underlying mutual funds or exchange-traded funds. Although not included in a fund's expenses, a fund indirectly bears its proportionate share of these expenses through the net asset value of each underlying mutual fund or exchange-traded fund. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.
Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. The Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction.
Distributions are declared and recorded daily and paid monthly from net investment income. Distributions from realized gains, if any, are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.
Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Capital accounts are not adjusted for temporary book-tax differences which will reverse in a subsequent period.
Book-tax differences are primarily due to market discount and capital loss carryforwards.
The Fund purchases municipal securities whose interest, in the opinion of the issuer, is free from federal income tax. There is no assurance that the IRS will agree with this opinion. In the event the IRS determines that the issuer does not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued.
As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows:
Gross unrealized appreciation
$6,456,164
Gross unrealized depreciation
(2,623,879)
Net unrealized appreciation (depreciation)
$3,832,285
Tax cost

Capital loss carryforwards are only available to offset future capital gains of the Fund to the extent provided by regulations and may be limited. The capital loss carryforward information presented below, including any applicable limitation, is estimated as of prior fiscal period end and is subject to adjustment.

5. Fees and Other Transactions with Affiliates.
Management Fee. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee that is based on an annual rate of .55% of the Fund's average net assets. Under the management contract, the investment adviser pays all other expenses, except the compensation of the independent Trustees and certain other expenses such as interest expense. The management fee is reduced by an amount equal to the fees and expenses paid by the Fund to the independent Trustees.
Interfund Trades. Funds may purchase from or sell securities to other Fidelity Funds under procedures adopted by the Board of Trustees. The procedures have been designed to ensure these interfund trades are executed in accordance with Rule 17a-7 of the 1940 Act. Any interfund trades are included within the respective purchases and sales amounts shown in the Purchases and Sales of Investments note. During the period, there were no interfund trades.
6. Committed Line of Credit.
Certain Funds participate with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes.
Commitment fees are charged based on the unused amount of the line of credit at an annual rate of .10%, and then allocated to each participating fund based on its pro-rata portion of the line of credit. The commitment fees are borne by the investment adviser.
Interest is charged to a participating fund based on its borrowings at an annual rate of .75% plus the highest of (i) daily SOFR plus a .10% spread adjustment, (ii) Federal Funds Effective Rate, or (iii) Overnight Bank Funding Rate. During the period, there were no borrowings on this line of credit.
The line of credit agreement will expire in March 2027 unless extended or renewed.
Effective March 24, 2026 the .10% spread adjustment on the SOFR benchmark was removed.
7. Expense Reductions.
Through arrangements with the Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expenses by $38.
8. Other.
A fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the fund. In the normal course of business, a fund may also enter into contracts that provide general indemnifications. A fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against a fund. The risk of material loss from such claims is considered remote.
9. Risk and Uncertainties.
Many factors affect a fund's performance. Developments that disrupt global economies and financial markets, such as public health emergencies, military conflicts, terrorism, government restrictions, political changes, and environmental disasters, may significantly affect a fund's investment performance. The effects of these developments to a fund will be impacted by the types of securities in which a fund invests, the financial condition, industry, economic sector, and geographic location of an issuer, and a fund's level of investment in the securities of that issuer. Significant concentrations in security types, issuers, industries, sectors, and geographic locations may magnify the factors that affect a fund's performance.

Board Approval of Investment Advisory Contracts and Management Fees
Fidelity Maryland Municipal Income Fund
Each year, the Board of Trustees, including the Independent Trustees (together, the Board), considers the renewal of the fund's management contract with Fidelity Management & Research Company LLC (FMR) and the sub-advisory agreements (together, the Advisory Contracts) for the fund. FMR and the sub-advisers are referred to herein as the Investment Advisers. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.
The Board meets regularly and, at each of its meetings, covers an extensive agenda of topics and materials and considers factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board's Operations Committee, of which all the Independent Trustees are members, meets regularly throughout the year and requests, receives and considers, among other matters, information related to the annual consideration of the renewal of the fund's Advisory Contracts before making its recommendation to the Board. The Board also meets as needed to review matters specifically related to the Board's annual consideration of the renewal of the Advisory Contracts. Members of the Board may also meet from time to time with trustees of other Fidelity U.S. registered funds (Fidelity funds) through joint ad hoc committees to discuss certain matters relevant to all of the Fidelity funds.
At its September 2025 meeting, the Board unanimously determined to renew the fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness relative to peer funds of the fund's management fee and total expense ratio; (iii) the total costs of the services provided by and the profits realized by FMR and its affiliates (Fidelity) from its relationships with the fund; and (iv) the extent to which, if any, economies of scale exist and are realized as the fund grows, and whether any economies of scale are appropriately shared with fund shareholders. The Board also considered the broad range of investment choices available to shareholders from FMR's competitors and that the fund's shareholders have chosen to invest in the fund, which is part of the Fidelity family of funds. The Board's decision to renew the Advisory Contracts was not based on any single factor and the factors may have been weighed differently by individual Trustees.
The Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts was in the best interests of the fund and its shareholders and that the compensation payable under the Advisory Contracts was fair and reasonable in light of all of the surrounding circumstances.
Nature, Extent, and Quality of Services Provided. The Board considered the Investment Advisers' staffing as it relates to the fund, including the backgrounds and experience of investment personnel, and also considered the Investment Advisers' implementation of the fund's investment program. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the investment personnel compensation program and whether this structure provides appropriate incentives to act in the best interests of the fund. Additionally, the Board considered the portfolio managers' investments, if any, in the funds that they manage.
Resources Dedicated to Investment Management and Support Services. The Board reviewed the general qualifications and capabilities of the Investment Advisers' staff, such as size, education, experience, and resources, as well as the Investment Advisers' approach to recruiting, managing, training, and compensating investment personnel. The Board noted that Fidelity's analysts have extensive resources, tools and capabilities that allow them to conduct quantitative and fundamental analysis, as well as credit analysis of issuers, counterparties and guarantors. Further, the Board considered that the Investment Advisers' investment professionals have sufficient access to information and data so as to provide competitive investment results over time, and that those professionals also have access to sophisticated tools that permit them to assess portfolio construction and risk and performance attribution characteristics continuously, and to transmit new information and research conclusions rapidly. Additionally, in its deliberations, the Board considered Fidelity's trading, risk management, compliance, cybersecurity, technology and operations capabilities and resources, which are integral parts of the investment management process.
Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by Fidelity under the Advisory Contracts and under separate agreements covering transfer agency and pricing and bookkeeping services for the fund; (ii) the nature and extent of Fidelity's supervision of third party service providers, principally custodians, subcustodians, and pricing vendors; and (iii) the resources devoted by Fidelity to, and the record of compliance with, the fund's compliance policies and procedures, including with respect to liquidity risk management.
The Board noted that the growth of fund assets over time across the complex allows Fidelity to reinvest in the development of services designed to enhance the value and convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account and market information over the Internet, via the Fidelity mobile app and through telephone representatives, investor education materials and asset allocation tools. The Board also considered that it reviews customer service metrics such as telephone response times, continuity of services on the website and metrics addressing services at Fidelity Investor Centers.
Investment in a Large Fund Family. The Board considered the benefits to shareholders of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing a large variety of fund investor services. The Board noted that Fidelity had taken, or had made recommendations to the Board that resulted in the Fidelity funds taking, a number of actions over the previous year that benefited particular funds and/or the Fidelity funds in general.
Investment Performance. The Board took into account discussions that occur with representatives of the Investment Advisers, and reports that it receives, at Board meetings throughout the year relating to fund investment performance. In this regard the Board noted that as part of regularly scheduled fund reviews and other reports to the Board on fund performance, the Board considered annualized return information for the fund for different time periods, measured against an appropriate index (benchmark index) and an appropriate peer group of funds with similar objectives (peer group). The Board also considered information about performance attribution. In its evaluation of fund investment performance at meetings throughout the year, the Board gave particular attention to information indicating underperformance of certain Fidelity funds over different time periods and discussed with the Investment Advisers the reasons for such underperformance.
In addition to reviewing absolute and relative fund performance, the Independent Trustees periodically consider the appropriateness of fund performance metrics in evaluating the results achieved. The Independent Trustees generally give greater weight to fund performance over longer time periods than over shorter time periods. Depending on the circumstances, the Independent Trustees may be satisfied with a fund's performance notwithstanding that it lags its benchmark index or peer group for certain periods.
Based on its review, the Board concluded that the nature, extent, and quality of services provided to the fund under the Advisory Contracts should continue to benefit the shareholders of the fund.
Competitiveness of Management Fee and Total Expense Ratio. The Board was provided with information regarding industry trends in management fees and expenses. In its review of the fund's management fee and total expense ratio, the Board considered the fund's all-inclusive (subject to certain limited exceptions) fee rate. The Board also considered other expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees, paid by FMR under the all-inclusive arrangement. The Board noted that Fidelity may agree to waive fees or reimburse expenses from time to time, and the extent to which, if any, it has done so for the fund.
Comparisons of Management Fees and Total Expense Ratios. Among other things, the Board reviewed data for selected groups of competitive funds and classes (referred to as "total peer groups") that were compiled by Fidelity based on combining similar Morningstar categories that have comparable investment mandates and sales load types (as classified by Lipper). The data reviewed by the Board included (i) gross management fee comparisons (before taking into account expense reimbursements or caps) of the fund relative to the funds and classes in the total peer group; (ii) gross management fee comparisons of the fund relative to a subset of non-Fidelity funds in the total peer group that are similar in size to the fund (referred to as the "asset-sized peer group"); (iii) total expense comparisons of the fund relative to the total peer group; and (iv) total expense comparisons (excluding performance adjustments and fund-paid 12b-1 fees) of the fund relative to the asset-sized peer group. The asset-sized peer group comparison excludes performance adjustments and fund-paid 12b-1 fees to eliminate variability in fee structures.
The information provided to the Board indicated that the fund's management fee rate ranked above the competitive median of the total peer group for 2024 and above the competitive median of the asset-sized peer group for 2024. Further, the information provided to the Board indicated that the total expense ratio of the fund ranked above the competitive median of the total peer group for 2024 and above the competitive median of the asset-sized peer group for 2024.
The Board considered that the fund has an all-inclusive management fee that covers expenses beyond portfolio management, unlike the majority of funds within the mapped group. The Board also noted that, although total expenses ranked four basis points above the total peer group median, Fidelity believes the fees charged are reasonable for the overall value of the nature and quality of services shareholders receive.
Fees Charged to Other Fidelity Clients. The Board also considered Fidelity fee structures and other information with respect to clients of Fidelity other than the fund, such as other funds advised or subadvised by Fidelity, pension plan clients, and other institutional clients with similar investment mandates. The Board noted that a joint ad hoc committee created by it and the boards of other Fidelity funds periodically reviews and compares Fidelity's institutional investment advisory business with its business of providing services to the Fidelity funds and also noted the most recent findings of the committee. The Board noted that the committee's review included a consideration of the differences in services provided, fees charged, and costs incurred, as well as competition in the markets serving the different categories of clients.
Based on its review, the Board concluded that the fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered. Further, based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that the fund's total expense ratio was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.
Costs of the Services and Profitability. The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and servicing the fund's shareholders. The Board also considered the level of Fidelity's profits in respect of the fund and all the Fidelity funds.
On an annual basis, Fidelity presents to the Board information about the profitability of its relationships with the fund. Fidelity calculates profitability information for each Fidelity fund, as well as aggregate profitability information for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the books and records of Fidelity on which Fidelity's audited financial statements are based. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies.
A public accounting firm has been engaged annually by the Board as part of the Board's assessment of Fidelity's profitability analysis. The engagement includes the review and assessment of the methodologies used by Fidelity in determining the revenues and expenses attributable to Fidelity's fund business. After considering the reports issued under the engagement and information provided by Fidelity, the Board concluded that while other allocation methods may also be reasonable, Fidelity's profitability methodologies are reasonable in all material respects.
The Board also reviewed Fidelity's non-fund businesses and potential indirect benefits such businesses may have received as a result of their association with Fidelity's fund business (i.e., fall-out benefits) as well as cases where Fidelity's affiliates may benefit from the funds' business. The Board considered areas where potential indirect benefits to the Fidelity funds from their relationships with Fidelity may exist. The Board's consideration of these matters was informed by the findings of a joint ad hoc committee created by it and the boards of other Fidelity funds to evaluate potential fall-out benefits.
The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund and was satisfied that the profitability was not excessive.
Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) and their shareholders have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale as assets grow through increased services to the fund, through waivers or reimbursements, or through fee or expense ratio reductions. The Board recognized that, due to the fund's current contractual arrangements, its expense ratio will not decline if the fund's operating costs decrease as assets grow, or rise as assets decrease. The Board also noted that a committee created by it and the boards of other Fidelity funds periodically analyzes whether Fidelity attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale. The Board's consideration of these matters was informed by the findings of the committee.
The Board concluded, taking into account the analysis of the committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.
Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' advisory contracts, the Board requested and received additional information on certain topics, including: (i) portfolio manager changes that have occurred during the past year; (ii) hiring, training, compensating, and retaining adviser and sub-adviser personnel; (iii) the terms of the funds' various management fee structures and arrangements for transfer agent and pricing and bookkeeping services; (iv) Fidelity's fund profitability methodology, profitability trends for certain funds and asset classes, the allocation of various costs to different funds, and the impact of certain factors on fund profitability results; (v) information about the role of fund profitability in considering changes to the fund lineup; (vi) the types of management fee and total expense comparisons provided, and challenges and limitations associated with such information; (vii) explanations regarding the relative total expense ratios and management fees of certain funds and classes, total expense and management fee competitive trends, and methodologies for total expense and management fee competitive comparisons; (viii) matters related to money market funds, bond funds, allocation funds, exchange-traded funds, and target date funds; (ix) the arrangements with and compensation paid to certain fund sub-advisers and the treatment of such compensation within Fidelity's fund profitability methodology; and (x) the terms of management contracts between Fidelity and other funds and products not overseen by the Board.
Conclusion. Based on its evaluation of all of the conclusions noted above, and after considering all factors it believed relevant, the Board, including the Independent Trustees, concluded that the advisory and sub-advisory fee arrangements are fair and reasonable in light of all of the surrounding circumstances and that the fund's Advisory Contracts should be renewed through September 30, 2026.

For the period ended February 28, 2026
1. Organization.
Fidelity Arizona Municipal Income Fund (the Fund) is a non-diversified fund of Fidelity Union Street Trust (the Trust) and is authorized to issue an unlimited number of shares. Share transactions on the Statement of Changes in Net Assets may contain exchanges between affiliated funds. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund may be affected by economic and political developments in the state of Arizona.
2. Investments in Fidelity Central Funds.
Funds may invest in Fidelity Central Funds, which are open-end investment companies generally available only to other investment companies and accounts managed by the investment adviser and its affiliates. The Schedule of Investments lists any Fidelity Central Funds held as an investment as of period end, but does not include the underlying holdings of each Fidelity Central Fund. An investing fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.
Based on its investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the investing fund. These strategies are consistent with the investment objectives of the investing fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity Central Funds and thus a decline in the value of the investing fund.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds which contain the significant accounting policies (including investment valuation policies) of those funds, and are not covered by the Report of Independent Registered Public Accounting Firm, are available on the Securities and Exchange Commission website or upon request.
3. Significant Accounting Policies.
The Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services - Investment Companies. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. The Fund operates as a single operating segment. The Fund's income, expenses, assets, and performance are regularly monitored and assessed as a whole by the investment adviser and other individuals responsible for oversight functions of the Trust, using the information presented in the financial statements and financial highlights. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The Fund's Schedule of Investments lists any underlying mutual funds or exchange-traded funds but does not include the underlying holdings of these funds. The following summarizes the significant accounting policies of the Fund:
Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Board of Trustees (the Board) has designated the Fund's investment adviser as the valuation designee responsible for the fair valuation function and performing fair value determinations as needed. The investment adviser has established a Fair Value Committee (the Committee) to carry out the day-to-day fair valuation responsibilities and has adopted policies and procedures to govern the fair valuation process and the activities of the Committee. In accordance with these fair valuation policies and procedures, which have been approved by the Board, the Fund attempts to obtain prices from one or more third party pricing services or brokers to value its investments. When current market prices, quotations or currency exchange rates are not readily available or reliable, investments will be fair valued in good faith by the Committee, in accordance with the policies and procedures. Factors used in determining fair value vary by investment type and may include market or investment specific events, transaction data, estimated cash flows, and market observations of comparable investments. The frequency that the fair valuation procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee manages the Fund's fair valuation practices and maintains the fair valuation policies and procedures. The Fund's investment adviser reports to the Board information regarding the fair valuation process and related material matters.
The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:
Level 1 - unadjusted quoted prices in active markets for identical investments
Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)
Valuation techniques used to value the Fund's investments by major category are as follows:
Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing services or from brokers who make markets in such securities. Municipal securities are valued by pricing services who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing services. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.
Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.
Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level as of February 28, 2026 is included at the end of the Fund's Schedule of Investments.
Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Debt obligations may be placed on non-accrual status and related interest income may be reduced by ceasing current accruals and writing off interest receivables when the collection of all or a portion of interest has become doubtful based on consistently applied procedures. A debt obligation is removed from non-accrual status when the issuer resumes interest payments or when collectability of interest is reasonably assured.
Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expenses included in the accompanying financial statements reflect the expenses of that fund and do not include any expenses associated with any underlying mutual funds or exchange-traded funds. Although not included in a fund's expenses, a fund indirectly bears its proportionate share of these expenses through the net asset value of each underlying mutual fund or exchange-traded fund. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.
Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. The Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction.
Distributions are declared and recorded daily and paid monthly from net investment income. Distributions from realized gains, if any, are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.
Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Capital accounts are not adjusted for temporary book-tax differences which will reverse in a subsequent period.
Book-tax differences are primarily due to market discount and capital loss carryforwards.
The Fund purchases municipal securities whose interest, in the opinion of the issuer, is free from federal income tax. There is no assurance that the IRS will agree with this opinion. In the event the IRS determines that the issuer does not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued.
As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows:
Gross unrealized appreciation
$3,929,095
Gross unrealized depreciation
(2,645,912)

Capital loss carryforwards are only available to offset future capital gains of the Fund to the extent provided by regulations and may be limited. The capital loss carryforward information presented below, including any applicable limitation, is estimated as of prior fiscal period end and is subject to adjustment.

Delayed Delivery Transactions and When-Issued Securities. During the period, certain Funds transacted in securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. Securities purchased on a delayed delivery or when-issued basis are identified as such in the Schedule of Investments. Compensation for interest forgone in the purchase of a delayed delivery or when-issued debt security may be received. With respect to purchase commitments, each applicable Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Payables and receivables associated with the purchases and sales of delayed delivery securities having the same coupon, settlement date and broker are offset. Delayed delivery or when-issued securities that have been purchased from and sold to different brokers are reflected as both payables and receivables in the Statement of Assets and Liabilities under the caption "Delayed delivery", as applicable. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.
4. Purchases and Sales of Investments.
Purchases and sales of securities, other than short-term securities and in-kind transactions, as applicable, are noted in the table below.

5. Fees and Other Transactions with Affiliates.
Management Fee. Fidelity Management & Research Company LLC (the investment adviser) and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee that is based on an annual rate of .55% of the Fund's average net assets. Under the management contract, the investment adviser pays all other expenses, except the compensation of the independent Trustees and certain other expenses such as interest expense. The management fee is reduced by an amount equal to the fees and expenses paid by the Fund to the independent Trustees.
Interfund Trades. Funds may purchase from or sell securities to other Fidelity Funds under procedures adopted by the Board of Trustees. The procedures have been designed to ensure these interfund trades are executed in accordance with Rule 17a-7 of the 1940 Act. Any interfund trades are included within the respective purchases and sales amounts shown in the Purchases and Sales of Investments note. During the period, there were no interfund trades.
6. Committed Line of Credit.
Certain Funds participate with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes.
Commitment fees are charged based on the unused amount of the line of credit at an annual rate of .10%, and then allocated to each participating fund based on its pro-rata portion of the line of credit. The commitment fees are borne by the investment adviser.
Interest is charged to a participating fund based on its borrowings at an annual rate of .75% plus the highest of (i) daily SOFR plus a .10% spread adjustment, (ii) Federal Funds Effective Rate, or (iii) Overnight Bank Funding Rate. During the period, there were no borrowings on this line of credit.
The line of credit agreement will expire in March 2027 unless extended or renewed.
Effective March 24, 2026 the .10% spread adjustment on the SOFR benchmark was removed.
7. Expense Reductions.
Through arrangements with the Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expenses by $17.
8. Other.
A fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the fund. In the normal course of business, a fund may also enter into contracts that provide general indemnifications. A fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against a fund. The risk of material loss from such claims is considered remote.
9. Risk and Uncertainties.
Many factors affect a fund's performance. Developments that disrupt global economies and financial markets, such as public health emergencies, military conflicts, terrorism, government restrictions, political changes, and environmental disasters, may significantly affect a fund's investment performance. The effects of these developments to a fund will be impacted by the types of securities in which a fund invests, the financial condition, industry, economic sector, and geographic location of an issuer, and a fund's level of investment in the securities of that issuer. Significant concentrations in security types, issuers, industries, sectors, and geographic locations may magnify the factors that affect a fund's performance.

Board Approval of Investment Advisory Contracts and Management Fees
Fidelity Arizona Municipal Income Fund
Each year, the Board of Trustees, including the Independent Trustees (together, the Board), considers the renewal of the fund's management contract with Fidelity Management & Research Company LLC (FMR) and the sub-advisory agreements (together, the Advisory Contracts) for the fund. FMR and the sub-advisers are referred to herein as the Investment Advisers. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.
The Board meets regularly and, at each of its meetings, covers an extensive agenda of topics and materials and considers factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board's Operations Committee, of which all the Independent Trustees are members, meets regularly throughout the year and requests, receives and considers, among other matters, information related to the annual consideration of the renewal of the fund's Advisory Contracts before making its recommendation to the Board. The Board also meets as needed to review matters specifically related to the Board's annual consideration of the renewal of the Advisory Contracts. Members of the Board may also meet from time to time with trustees of other Fidelity U.S. registered funds (Fidelity funds) through joint ad hoc committees to discuss certain matters relevant to all of the Fidelity funds.
At its September 2025 meeting, the Board unanimously determined to renew the fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness relative to peer funds of the fund's management fee and total expense ratio; (iii) the total costs of the services provided by and the profits realized by FMR and its affiliates (Fidelity) from its relationships with the fund; and (iv) the extent to which, if any, economies of scale exist and are realized as the fund grows, and whether any economies of scale are appropriately shared with fund shareholders. The Board also considered the broad range of investment choices available to shareholders from FMR's competitors and that the fund's shareholders have chosen to invest in the fund, which is part of the Fidelity family of funds. The Board's decision to renew the Advisory Contracts was not based on any single factor and the factors may have been weighed differently by individual Trustees.
The Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts was in the best interests of the fund and its shareholders and that the compensation payable under the Advisory Contracts was fair and reasonable in light of all of the surrounding circumstances.
Nature, Extent, and Quality of Services Provided. The Board considered the Investment Advisers' staffing as it relates to the fund, including the backgrounds and experience of investment personnel, and also considered the Investment Advisers' implementation of the fund's investment program. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the investment personnel compensation program and whether this structure provides appropriate incentives to act in the best interests of the fund. Additionally, the Board considered the portfolio managers' investments, if any, in the funds that they manage.
Resources Dedicated to Investment Management and Support Services. The Board reviewed the general qualifications and capabilities of the Investment Advisers' staff, such as size, education, experience, and resources, as well as the Investment Advisers' approach to recruiting, managing, training, and compensating investment personnel. The Board noted that Fidelity's analysts have extensive resources, tools and capabilities that allow them to conduct quantitative and fundamental analysis, as well as credit analysis of issuers, counterparties and guarantors. Further, the Board considered that the Investment Advisers' investment professionals have sufficient access to information and data so as to provide competitive investment results over time, and that those professionals also have access to sophisticated tools that permit them to assess portfolio construction and risk and performance attribution characteristics continuously, and to transmit new information and research conclusions rapidly. Additionally, in its deliberations, the Board considered Fidelity's trading, risk management, compliance, cybersecurity, technology and operations capabilities and resources, which are integral parts of the investment management process.
Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by Fidelity under the Advisory Contracts and under separate agreements covering transfer agency and pricing and bookkeeping services for the fund; (ii) the nature and extent of Fidelity's supervision of third party service providers, principally custodians, subcustodians, and pricing vendors; and (iii) the resources devoted by Fidelity to, and the record of compliance with, the fund's compliance policies and procedures, including with respect to liquidity risk management.
The Board noted that the growth of fund assets over time across the complex allows Fidelity to reinvest in the development of services designed to enhance the value and convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account and market information over the Internet, via the Fidelity mobile app and through telephone representatives, investor education materials and asset allocation tools. The Board also considered that it reviews customer service metrics such as telephone response times, continuity of services on the website and metrics addressing services at Fidelity Investor Centers.
Investment in a Large Fund Family. The Board considered the benefits to shareholders of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing a large variety of fund investor services. The Board noted that Fidelity had taken, or had made recommendations to the Board that resulted in the Fidelity funds taking, a number of actions over the previous year that benefited particular funds and/or the Fidelity funds in general.
Investment Performance. The Board took into account discussions that occur with representatives of the Investment Advisers, and reports that it receives, at Board meetings throughout the year relating to fund investment performance. In this regard the Board noted that as part of regularly scheduled fund reviews and other reports to the Board on fund performance, the Board considered annualized return information for the fund for different time periods, measured against an appropriate index (benchmark index) and an appropriate peer group of funds with similar objectives (peer group). The Board also considered information about performance attribution. In its evaluation of fund investment performance at meetings throughout the year, the Board gave particular attention to information indicating underperformance of certain Fidelity funds over different time periods and discussed with the Investment Advisers the reasons for such underperformance.
In addition to reviewing absolute and relative fund performance, the Independent Trustees periodically consider the appropriateness of fund performance metrics in evaluating the results achieved. The Independent Trustees generally give greater weight to fund performance over longer time periods than over shorter time periods. Depending on the circumstances, the Independent Trustees may be satisfied with a fund's performance notwithstanding that it lags its benchmark index or peer group for certain periods.
Based on its review, the Board concluded that the nature, extent, and quality of services provided to the fund under the Advisory Contracts should continue to benefit the shareholders of the fund.
Competitiveness of Management Fee and Total Expense Ratio. The Board was provided with information regarding industry trends in management fees and expenses. In its review of the fund's management fee and total expense ratio, the Board considered the fund's all-inclusive (subject to certain limited exceptions) fee rate. The Board also considered other expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees, paid by FMR under the all-inclusive arrangement. The Board noted that Fidelity may agree to waive fees or reimburse expenses from time to time, and the extent to which, if any, it has done so for the fund.
Comparisons of Management Fees and Total Expense Ratios. Among other things, the Board reviewed data for selected groups of competitive funds and classes (referred to as "total peer groups") that were compiled by Fidelity based on combining similar Morningstar categories that have comparable investment mandates and sales load types (as classified by Lipper). The data reviewed by the Board included (i) gross management fee comparisons (before taking into account expense reimbursements or caps) of the fund relative to the funds and classes in the total peer group; (ii) gross management fee comparisons of the fund relative to a subset of non-Fidelity funds in the total peer group that are similar in size to the fund (referred to as the "asset-sized peer group"); (iii) total expense comparisons of the fund relative to the total peer group; and (iv) total expense comparisons (excluding performance adjustments and fund-paid 12b-1 fees) of the fund relative to the asset-sized peer group. The asset-sized peer group comparison excludes performance adjustments and fund-paid 12b-1 fees to eliminate variability in fee structures.
The information provided to the Board indicated that the fund's management fee rate ranked above the competitive median of the total peer group for 2024 and above the competitive median of the asset-sized peer group for 2024. Further, the information provided to the Board indicated that the total expense ratio of the fund ranked above the competitive median of the total peer group for 2024 and below the competitive median of the asset-sized peer group for 2024.
The Board considered that the fund has an all-inclusive management fee that covers expenses beyond portfolio management, unlike the majority of funds within the mapped group. The Board also noted that, although total expenses ranked four basis points above the total peer group median, Fidelity believes the fees charged are reasonable for the overall value of the nature and quality of services shareholders receive.
Fees Charged to Other Fidelity Clients. The Board also considered Fidelity fee structures and other information with respect to clients of Fidelity other than the fund, such as other funds advised or subadvised by Fidelity, pension plan clients, and other institutional clients with similar investment mandates. The Board noted that a joint ad hoc committee created by it and the boards of other Fidelity funds periodically reviews and compares Fidelity's institutional investment advisory business with its business of providing services to the Fidelity funds and also noted the most recent findings of the committee. The Board noted that the committee's review included a consideration of the differences in services provided, fees charged, and costs incurred, as well as competition in the markets serving the different categories of clients.
Based on its review, the Board concluded that the fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered. Further, based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that the fund's total expense ratio was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.
Costs of the Services and Profitability. The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and servicing the fund's shareholders. The Board also considered the level of Fidelity's profits in respect of the fund and all the Fidelity funds.
On an annual basis, Fidelity presents to the Board information about the profitability of its relationships with the fund. Fidelity calculates profitability information for each Fidelity fund, as well as aggregate profitability information for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the books and records of Fidelity on which Fidelity's audited financial statements are based. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies.
A public accounting firm has been engaged annually by the Board as part of the Board's assessment of Fidelity's profitability analysis. The engagement includes the review and assessment of the methodologies used by Fidelity in determining the revenues and expenses attributable to Fidelity's fund business. After considering the reports issued under the engagement and information provided by Fidelity, the Board concluded that while other allocation methods may also be reasonable, Fidelity's profitability methodologies are reasonable in all material respects.
The Board also reviewed Fidelity's non-fund businesses and potential indirect benefits such businesses may have received as a result of their association with Fidelity's fund business (i.e., fall-out benefits) as well as cases where Fidelity's affiliates may benefit from the fund's business. The Board considered areas where potential indirect benefits to the Fidelity funds from their relationships with Fidelity may exist. The Board's consideration of these matters was informed by the findings of a joint ad hoc committee created by it and the boards of other Fidelity funds to evaluate potential fall-out benefits.
The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund and was satisfied that the profitability was not excessive.
Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) and their shareholders have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale as assets grow through increased services to the fund, through waivers or reimbursements, or through fee or expense ratio reductions. The Board recognized that, due to the fund's current contractual arrangements, its expense ratio will not decline if the fund's operating costs decrease as assets grow, or rise as assets decrease. The Board also noted that a committee created by it and the boards of other Fidelity funds periodically analyzes whether Fidelity attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale. The Board's consideration of these matters was informed by the findings of the committee.
The Board concluded, taking into account the analysis of the committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.
Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' advisory contracts, the Board requested and received additional information on certain topics, including: (i) portfolio manager changes that have occurred during the past year; (ii) hiring, training, compensating, and retaining adviser and sub-adviser personnel; (iii) the terms of the funds' various management fee structures and arrangements for transfer agent and pricing and bookkeeping services; (iv) Fidelity's fund profitability methodology, profitability trends for certain funds and asset classes, the allocation of various costs to different funds, and the impact of certain factors on fund profitability results; (v) information about the role of fund profitability in considering changes to the fund lineup; (vi) the types of management fee and total expense comparisons provided, and challenges and limitations associated with such information; (vii) explanations regarding the relative total expense ratios and management fees of certain funds and classes, total expense and management fee competitive trends, and methodologies for total expense and management fee competitive comparisons; (viii) matters related to money market funds, bond funds, allocation funds, exchange-traded funds, and target date funds; (ix) the arrangements with and compensation paid to certain fund sub-advisers and the treatment of such compensation within Fidelity's fund profitability methodology; and (x) the terms of management contracts between Fidelity and other funds and products not overseen by the Board.
Conclusion. Based on its evaluation of all of the conclusions noted above, and after considering all factors it believed relevant, the Board, including the Independent Trustees, concluded that the advisory fee arrangements are fair and reasonable in light of all of the surrounding circumstances and that the fund's Advisory Contracts should be renewed through September 30, 2026.
