What affected the Fund's performance this period?

•For the 12 months ending July 31, 2026, most commodities gained despite a backdrop of geopolitical uncertainty. The following returns are stated on a total return basis for the three-month forward benchmark components.

•Against this backdrop, the fund benefited from its significant exposure to energy commodities, which gained 21% over the period as geopolitical tensions tightened the supply of oil. Refined petroleum products soared, with low Sulphur gas oil, heating oil and gasoline advancing 95%, 94% and 57%, respectively, according to the benchmark. West Texas intermediate crude (+35%) and Brent crude (+29%) oil also both sharply gained. Natural gas, however, returned about -37%, struggling amid higher supply.

•Precious metals (+33%) performed strongly, with gold and silver gaining 22% and 56%, respectively, according to Bloomberg. Industrial metals (+33%) also had a favorable result. Within the sector, copper (+46%) benefited from tight supply and demand driven by electrification, while zinc (+37%), aluminum (+30%) and nickel (+15%) also posted positive returns. Lead (-7%) struggled.

•Meanwhile, the agriculture sector gained roughly 14% overall, led by soybean oil (+30%), coffee (+30%), soybeans (+25%) and Kansas City wheat (+22%). Soybean meal (+15%), cotton (+14%), wheat (+11%) and corn (+4%) also generated positive results. In contrast, cocoa (-26%) and sugar (-10%) lost ground.

•Livestock, meanwhile, gained 6%, driven by live cattle (+10%). Lean hogs, however, modestly declined, returning -1%.

How did the Fund perform over the past 10 years?

The trust's Audit Committee has considered non-audit services that were not pre-approved that were provided by Deloitte Entities and PwC to Fund Service Providers to be compatible with maintaining the independence of Deloitte Entities and PwC in its(their) audit of the Fund(s), taking into account representations from Deloitte Entities and PwC, in accordance with Public Company Accounting Oversight Board rules, regarding its independence from the Fund(s) and its(their) related entities and Geode’s review of the appropriateness and permissibility under applicable law of such non-audit services prior to their provision to the Fund(s) Service Providers.

Audit Committee Pre-Approval Policies and Procedures

The trust’s Audit Committee must pre-approve all audit and non-audit services provided by a fund’s independent registered public accounting firm relating to the operations or financial reporting of the fund. Prior to the commencement of any audit or non-audit services to a fund, the Audit Committee reviews the services to determine whether they are appropriate and permissible under applicable law.

The Audit Committee has adopted policies and procedures to, among other purposes, provide a framework for the Committee’s consideration of non-audit services by the audit firms that audit the Fidelity funds. The policies and procedures require that any non-audit service provided by a fund audit firm to a Fidelity fund and any non-audit service provided by a fund auditor to a Fund Service Provider that relates directly to the operations and financial reporting of a Fidelity fund (“Covered Service”) are subject to approval by the Audit Committee before such service is provided.

All Covered Services must be approved in advance of provision of the service either: (i) by formal resolution of the Audit Committee, or (ii) by oral or written approval of the service by the Chair of the Audit Committee (or if the Chair is unavailable, such other member of the Audit Committee as may be designated by the Chair to act in the Chair’s absence). The approval contemplated by (ii) above is permitted where the Treasurer determines that action on such an engagement is necessary before the next meeting of the Audit Committee.

Non-audit services provided by a fund audit firm to a Fund Service Provider that do not relate directly to the operations and financial reporting of a Fidelity fund are reported to the Audit Committee periodically.

Non-Audit Services Approved Pursuant to Rule 2-01(c)(7)(i)(C) and (ii) of Regulation S-X (“De Minimis Exception”)

There were no non-audit services approved or required to be approved by the Audit Committee pursuant to the De Minimis Exception during the Fund’s(s’) last two fiscal years relating to services provided to (i) the Fund(s) or (ii) any Fund Service Provider that relate directly to the operations and financial reporting of the Fund(s).

The Registrant has not retained, for the preparation of the audit report on the financial statements included in the Form N-CSR, a registered public accounting firm that has a branch or office that is located in a foreign jurisdiction and that the Public Company Accounting Oversight Board (the “PCAOB”) has determined that the PCAOB is unable to inspect or investigate completely because of a position taken by an authority in the foreign jurisdiction.

The Registrant is not a “foreign issuer,” as defined in 17 CFR 240.3b-4.

Notes to Consolidated Financial Statements

For the period ended July 31, 2026

1. Organization.

Fidelity® Series Commodity Strategy Fund (the Fund) is a fund of Fidelity Oxford Street Trust (the Trust) and is authorized to issue an unlimited number of shares. 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.

Shares are offered only to certain other Fidelity funds, Fidelity managed 529 plans, and Fidelity managed collective investment trusts.

2. Consolidated Subsidiary.

Commodity-related investments are held through a wholly owned subsidiary (Subsidiary). As of period end, investments in Subsidiaries were as follows:

	Subsidiary Name	Net Assets of Subsidiary ($)	% of Fund's Total Assets
Fidelity® Series Commodity Strategy Fund	Geode Series Commodity Return Cayman Ltd.	236,152,063	18.7

The financial statements have been consolidated to include the Subsidiary accounts where applicable. Accordingly, all inter-company transactions and balances have been eliminated.

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 consolidated 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 consolidated financial statements. Actual results could differ from those estimates. The Fund operates as a single operating segment. The Fund's portfolio management team, part of the investment adviser, serves as the chief operating decision maker (CODM) and directs the Fund's investments in accordance with its investment objective and policies, with support from others responsible for oversight functions. The information reviewed by the CODM is consistent with the Fund's consolidated financial statements and consolidated financial highlights. Subsequent events, if any, through the date that the consolidated financial statements were issued have been evaluated in the preparation of the consolidated financial statements. The Fund's Consolidated 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. U.S. Treasury Obligations 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 and swaps may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing services. For any foreign debt securities, when significant market or security specific events arise, valuations may be determined in good faith in accordance with procedures adopted by the Board. Debt securities and swaps are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Swaps are marked-to-market daily based on valuations from third party pricing services, registered derivatives clearing organizations (clearinghouses) or broker-supplied valuations. These pricing sources may utilize inputs such as movements in the underlying index, interest rate curves, credit spread curves, default possibilities and recovery rates.

Futures contracts are valued at the settlement price or official closing price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy.

Investments in open-end mutual 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 period end is included at the end of the Fund's Consolidated Schedule of Investments.

Investment Transactions and Income. For financial reporting purposes, the investment holdings and net asset value (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 and include proceeds received from litigation.

Dividend income for domestic securities is recorded on the ex-dividend date. Certain dividends from any foreign securities where the ex-dividend date may have passed are recorded as soon as a fund is informed of the ex-dividend date. Non-cash dividends, if any, are recorded at the fair market value of the securities received.

Income and capital gain distributions from any underlying mutual funds or exchange-traded funds (ETFs) 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 consolidated 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.

As of July 31, 2026, the Fund did not have any unrecognized tax benefits in the consolidated financial statements; nor is the Fund aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

The Subsidiary is classified as a controlled foreign corporation under Subchapter N of the Internal Revenue Code. Therefore, the Fund is required to increase its taxable income by its share of the Subsidiary's income. Net investment losses of the Subsidiary cannot be deducted by the Fund in the current period nor carried forward to offset taxable income in future periods.

Distributions 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. These differences may result in distribution reclassifications.

In addition, the Fund claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

Capital accounts within the Consolidated 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: capital loss carryforwards and controlled foreign corporations.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows:

	Tax Cost ($)	Gross unrealized appreciation ($)	Gross unrealized depreciation ($)	Net unrealized appreciation (depreciation) ($)
Fidelity® Series Commodity Strategy Fund	1,239,619,147	10,966,248	-	10,966,248

The tax-based components of distributable earnings as of period end were as follows:

	Undistributed ordinary income ($)	Capital loss carryforward ($)	Net unrealized appreciation (depreciation) on securities and other investments ($)
Fidelity® Series Commodity Strategy Fund	391,570,122	(113,636,328)	7,598,873

Capital loss carryforwards are only available to offset future capital gains of the Funds 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 fiscal period end and is subject to adjustment.

	Short-term ($)	Long-term ($)	Total capital loss carryforward ($)
Fidelity® Series Commodity Strategy Fund	(85,536,856)	(28,099,472)	(113,636,328)

The tax character of distributions paid was as follows:

July 31, 2026
	Ordinary Income ($)	Total ($)
Fidelity® Series Commodity Strategy Fund	18,900,563	18,900,563

July 31, 2025
	Ordinary Income ($)	Total ($)
Fidelity® Series Commodity Strategy Fund	66,399,671	66,399,671

4. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Fund's investment objectives allow for various types of derivative instruments, including futures contracts and swaps. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party. Derivatives were primarily used to increase returns, to gain exposure to certain types of assets and to manage exposure to certain risks as defined below. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the objectives may not be achieved.

Derivatives were used to increase or decrease exposure to the following risk(s):

Commodity Risk

Commodity risk is the risk that the value of a commodity will fluctuate as a result of changes in market prices.

Funds are also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that a fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to a fund. Derivative counterparty credit risk is managed through formal evaluation of the creditworthiness of all potential counterparties

On certain OTC derivatives such as bi-lateral swaps, a fund attempts to reduce its exposure to counterparty credit risk by entering into an International Swaps and Derivatives Association, Inc. (ISDA) Master Agreement with each of its counterparties. The ISDA Master Agreement gives a fund the right to terminate all transactions traded under such agreement upon the deterioration in the credit quality of the counterparty beyond specified levels. The ISDA Master Agreement gives each party the right, upon an event of default by the other party or a termination of the agreement, to close out all transactions traded under such agreement and to net amounts owed under each transaction to one net payable by one party to the other. Upon entering into a swap, a fund is required to post an initial collateral amount (referred to as "Independent Amount"), as defined in the ISDA Master Agreement. A fund is required to post additional collateral for the benefit of counterparties to meet the counterparty's unrealized appreciation on outstanding swap contracts and any such posted collateral is identified on the Consolidated Schedule of Investments. To mitigate counterparty credit risk on bi-lateral OTC derivatives, a fund receives collateral in the form of cash or securities once net unrealized appreciation on outstanding derivative contracts under an ISDA Master Agreement exceeds certain applicable thresholds, subject to certain minimum transfer provisions. The collateral received is held in segregated accounts with the custodian bank in accordance with the collateral agreements entered into between a fund, the counterparty and the custodian bank. A fund could experience delays and costs in gaining access to the collateral even though it is held by the custodian bank. The maximum risk of loss to a fund from counterparty credit risk related to bi-lateral OTC derivatives is generally the aggregate unrealized appreciation and unpaid counterparty payments in excess of any collateral pledged by the counterparty to a fund. A fund may be required to pledge collateral for the benefit of the counterparties on bi-lateral OTC derivatives in an amount not less than each counterparty's unrealized appreciation on outstanding derivative contracts, subject to certain minimum transfer provisions, and any such pledged collateral is identified in the Consolidated Schedule of Investments.

Exchange-traded futures contracts are not covered by the ISDA Master Agreement; however counterparty credit risk related to exchange-traded futures contracts may be mitigated by the protection provided by the exchange's clearinghouse.

Investing in derivatives may involve greater risks than investing in the underlying assets directly and, to varying degrees, may involve risk of loss in excess of any initial investment and collateral received and amounts recognized in the Consolidated Statement of Assets and Liabilities. In addition, there may be the risk that the change in value of the derivative contract does not correspond to the change in value of the underlying instrument.

For futures contracts, reflects gross cumulative appreciation (depreciation) as presented in the Consolidated Schedule of Investments. In the Consolidated Statement of Assets and Liabilities, the period end variation margin is included in receivable or payable for variation margin on futures contracts, and the net cumulative appreciation (depreciation) is included in total accumulated earnings (loss).

Derivative Instruments Volume. The table below summarizes derivative instruments volume during the period. The average amount for forward foreign currency contracts represents contract value, and the average amount for all other derivative types represents notional amount, as applicable.

	Average Amount ($)

Futures	475,507,843

Futures Contracts. A futures contract is an agreement between two parties to buy or sell a specified underlying instrument for a fixed price at a specified future date. Futures contracts were used to manage exposure to the commodities market.

Upon entering into a futures contract, a fund is required to deposit either cash or securities (initial margin) with a clearing broker in an amount equal to a certain percentage of the face value of the contract. Futures contracts are marked-to-market daily. Subsequent payments from or to a fund are made as needed depending on the fluctuations in the value of the futures contracts and are recorded as unrealized appreciation or (depreciation). This receivable and/or payable, if any, is included in variation margin on futures contracts in the Consolidated Statement of Assets and Liabilities. Realized gain or (loss) is recorded upon the expiration or closing of a futures contract. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on futures contracts during the period is presented in the Consolidated Statement of Operations.

Any open futures contracts at period end are presented in the Consolidated Schedule of Investments under the caption "Futures Contracts". The notional amount at value reflects each contract's exposure to the underlying instrument or index at period end.

Any securities deposited to meet initial margin requirements are identified in the Consolidated Schedule of Investments. Any cash deposited to meet initial margin requirements is presented as segregated cash with brokers for derivative instruments in the Consolidated Statement of Assets and Liabilities.

Swaps. A swap is a contract between two parties to exchange future cash flows at periodic intervals based on a notional principal amount. A bi-lateral OTC swap is a transaction between a fund and a dealer counterparty where cash flows are exchanged between the two parties for the life of the swap. Once cleared, the clearinghouse serves as a central counterparty, with whom a fund exchanges cash flows for the life of the transaction, similar to transactions in futures contracts.

Bi-lateral OTC swaps are marked-to-market daily and changes in value are reflected in the Consolidated Statement of Assets and Liabilities in the bi-lateral OTC swaps at value line items. Any unamortized upfront premiums are presented in the Consolidated Schedule of Investments.

Payments are exchanged at specified intervals, accrued daily commencing with the effective date of the contract and recorded as realized gain or (loss). Some swaps may be terminated prior to the effective date and realize a gain or loss upon termination. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on swaps during the period is presented in the Consolidated Statement of Operations.

Any open swaps at period end are included in the Consolidated Schedule of Investments under the caption "Swaps".

Total Return Swaps. Total return swaps are agreements between counterparties to exchange cash flows, one based on a market-linked return of an individual asset or a basket of assets (i.e., an index), and the other on a fixed or floating rate. To the extent the total return of the instrument or index underlying the transaction exceeds or falls short of the offsetting payment obligation, a fund will receive a payment from or make a payment to the counterparty at the specified payment frequency. A fund enters into total return swaps to manage its market exposure.

5. Fees and Other Transactions with Affiliates.

Management Fee and Administrative Agreement. Geode Capital Management, LLC (the investment adviser) provides the Fund with investment management related services.

The Fund does not pay a management fee for these services.

Under the management contract, the investment adviser pays all other operating expenses, except custody fees, fees and expenses of the independent Trustees, and certain miscellaneous expenses such as proxy and shareholder meeting expenses.

FMR provides administrative services to the Fund and the Fund does not pay a fee for these services. The investment adviser also provides investment management services to the Subsidiary. The Subsidiary does not pay the investment adviser a fee for these services. The Subsidiary pays certain other expenses including custody and directors' fees.

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. During the period, there were no interfund trades.

6. Committed Line of Credit.

Certain Funds participate with other funds managed by FMR 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, (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.

7. Expense Reductions.

Through arrangements with the custodian, credits realized as a result of certain uninvested cash balances were used to reduce expenses. All of the applicable credits are presented in the table below.

	Custodian Credits ($)
Fidelity® Series Commodity Strategy Fund	3,672

Net increase (decrease)	4,725,435	(17,428,220)	246,964,695	(1,623,293,790)

10. 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.

At the end of the period, mutual funds and accounts managed by FMR or its affiliates were the owners of record of all of the outstanding shares of the Fund.

11. 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.

Notes to Consolidated Financial Statements

For the period ended July 31, 2026

1. Organization.

Fidelity® SAI Inflation-Focused Fund (the Fund) is a fund of Fidelity Oxford Street Trust (the Trust) and is authorized to issue an unlimited number of shares. 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.

Shares are offered exclusively to certain clients of Strategic Advisers LLC or its affiliates.

2. Consolidated Subsidiary.

Commodity-related investments are held through a wholly owned subsidiary (Subsidiary). As of period end, investments in Subsidiaries were as follows:

	Subsidiary Name	Net Assets of Subsidiary ($)	% of Fund's Total Assets
Fidelity® SAI Inflation-Focused Fund	Geode SAI Inflation-Focused Cayman Ltd.	1,429,822,448	20.2

The financial statements have been consolidated to include the Subsidiary accounts where applicable. Accordingly, all inter-company transactions and balances have been eliminated.

3. Significant Accounting Policies.

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. U.S. Treasury Obligations 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. For any foreign debt securities, when significant market or security specific events arise, valuations may be determined in good faith in accordance with procedures adopted by the Board. 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 are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Gains and losses on securities sold are determined on the basis of identified cost.

Income and capital gain distributions from any underlying mutual funds or exchange-traded funds (ETFs) are recorded on the ex-dividend date.

Distributions 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. These differences may result in distribution reclassifications.

In addition, the Fund claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

Book-tax differences are primarily due to: capital loss carryforwards and controlled foreign corporations.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes were as follows:

	Tax Cost ($)	Gross unrealized appreciation ($)	Gross unrealized depreciation ($)	Net unrealized appreciation (depreciation) ($)
Fidelity® SAI Inflation-Focused Fund	7,046,640,894	-	(11,458,260)	(11,458,260)

The tax-based components of distributable earnings as of period end were as follows:

	Undistributed ordinary income ($)	Capital loss carryforward ($)	Net unrealized appreciation (depreciation) on securities and other investments ($)
Fidelity® SAI Inflation-Focused Fund	2,029,691,972	(226,890,734)	(19,693,641)

	Short-term ($)	Long-term ($)	Total capital loss carryforward ($)
Fidelity® SAI Inflation-Focused Fund	(111,344,779)	(115,545,954)	(226,890,733)

Due to large subscriptions and redemptions in prior periods, some of the Fund's unrealized capital losses are subject to an annual limitation on their availability to offset capital gains in future periods. If those capital losses are realized and the limitation prevents the use of any of those capital losses in a future period, those capital losses will be available to offset capital gains in subsequent periods to the extent provided by regulations and subject to applicable limits.

The tax character of distributions paid was as follows:

July 31, 2026
	Ordinary Income ($)	Total ($)
Fidelity® SAI Inflation-Focused Fund	343,321,771	343,321,771

July 31, 2025
	Ordinary Income ($)	Total ($)
Fidelity® SAI Inflation-Focused Fund	191,786,297	191,786,297

4. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Fund's investment objectives allow for various types of derivative instruments, including futures contracts. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party. Derivatives were primarily used to increase returns, to gain exposure to certain types of assets and to manage exposure to certain risks as defined below. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the objectives may not be achieved.

Derivatives were used to increase or decrease exposure to the following risk(s):

Commodity Risk

Commodity risk is the risk that the value of a commodity will fluctuate as a result of changes in market prices.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Oxford Street Trust and the Shareholders of Fidelity SAI Inflation-Focused Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying consolidated statement of assets and liabilities of Fidelity SAI Inflation-Focused Fund (the "Fund"), a fund of Fidelity Oxford Street Trust, including the consolidated schedule of investments, as of July 31, 2026, the related consolidated statement of operations for the year then ended, statements of changes in net assets for each of the two years in the period then ended, financial highlights for each of the five years in the period then ended, and the related notes (collectively referred to as the "financial statements and financial highlights"). In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of July 31, 2026, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of July 31, 2026, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.
