**State Street Institutional Investment Trust**

**Notes to Financial Statements — March 31, 2026 (Unaudited)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

**1. Organization of the Funds**

State Street Institutional Investment Trust (the "Trust"), a Massachusetts business trust registered under the Investment Company Act of 1940, as amended ("1940 Act"), is an open-end management investment company.

As of March 31, 2026, the Trust consists of thirty-four (34) series (and corresponding classes, each of which have the same rights and privileges, including voting rights), each of which represents a separate series of beneficial interest in the Trust. The Declaration of Trust permits the Board of Trustees of the Trust (the "Board" and each member thereof, a "Trustee") to authorize the issuance of an unlimited number of shares of beneficial interest with no par value. The financial statements herein relate to the State Street U.S. Core Equity Fund and the State Street Income Fund (each, a "Fund" and collectively, the "Funds"). Shares of the Funds may be purchased only by Eligible Investors, as defined in the Funds' prospectus, through General Electric Company's defined contribution plan arrangement in a Fund.

Under the Trust's organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust. Additionally, in the normal course of business, the Trust enters into contracts with service providers that contain general indemnification clauses. The Trust's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred.

**2. Segment Reporting**

Each Fund has one reportable segment. Business activities are managed on a consolidated basis and revenues are derived primarily through each Fund's investments in accordance with its investment objective. Each Fund's chief operating decision maker ("CODM") is the President of the Trust. The CODM assesses performance based on a Fund's Total Return as reported in the Financial Highlights, and the same accounting policies are applied as described in the summary of significant accounting policies. Each Fund's Total Return is utilized by the CODM to compare results, including the impact of the Fund's costs, to a Fund's competitors and to a Fund's benchmark index.

**3. Summary of Significant Accounting Policies**

The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements:

The preparation of financial statements in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. Each Fund is an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

**Security Valuation** Each Fund's investments are valued at fair value each day that the New York Stock Exchange ("NYSE") is open and, for financial reporting purposes, as of the report date should the reporting period end on a day that the NYSE is not open. Fair value is generally defined as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. By its nature, a fair value price is a good faith estimate of the valuation in a current sale and may not reflect an actual market price. The investments of each Fund are valued pursuant to the policy and procedures developed by the Oversight Committee (the "Committee") and approved by the Board. The Committee provides oversight of the valuation of investments for the Funds. The Board has responsibility for overseeing the determination of the fair value of investments.

Valuation techniques used to value each Fund's investments by major category are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Equity investments (including preferred stocks and registered investment companies that are exchange-traded funds) traded on a recognized securities exchange for which market quotations are readily available are valued

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

**Notes to Financial Statements, continued — March 31, 2026 (Unaudited)**

at the last sale price or official closing price, as applicable, on the primary market or exchange on which they trade. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last published sale price or at fair value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fixed income assets are generally valued at the mean of the bid and ask prices for bank loans and inflation protected securities, and at the bid price for all other fixed income assets as provided by independent pricing services or brokers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Exchange-traded futures contracts are valued at the closing settlement price on the primary market on which they are traded most extensively. Exchange-traded futures contracts traded on a recognized exchange for which there were no sales on that day are valued at the last reported sale price obtained from independent pricing services or brokers or at fair value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Swap agreements are valued daily based upon prices supplied by Board approved pricing vendors or through brokers. Depending on the product and terms of the transaction, the value of agreements is determined using a series of techniques including valuation models that incorporate a number of market data factors, such as discounted cash flows, yields, curves, trades and values of the underlying reference instruments. In the event SSGA Funds Management, Inc. (the "Adviser" or "SSGA FM") is unable to obtain an independent, third-party valuation the agreements will be fair valued.

In the event prices or quotations are not readily available or that the application of these valuation methods results in a price for an investment that is deemed to be not representative of the fair value of such investment, fair value will be determined in good faith by the Committee, in accordance with the valuation policy and procedures approved by the Board.

The Funds value their assets and liabilities at fair value using a fair value hierarchy consisting of three broad levels that prioritize the inputs to valuation techniques giving the highest priority to readily available unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements) when market prices are not readily available or reliable. The categorization of a value determined for an investment within the hierarchy is based upon the pricing transparency of the investment and is not necessarily an indication of the risk associated with investing in it.

The three levels of the fair value hierarchy are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1 — Unadjusted quoted prices in active markets for an identical asset or liability;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability (such as exchange rates, financing terms, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3 — Unobservable inputs for the asset or liability, including the Committee's assumptions used in determining the fair value of investments.

The value of each Fund's investments according to the fair value hierarchy as of March 31, 2026 is disclosed in each Fund's respective Schedule of Investments.

**Investment Transactions and Income Recognition** Investment transactions are accounted for on trade date for financial reporting purposes. Realized gains and losses from the sale or disposition of investments and foreign exchange transactions, if any, are determined using the identified cost method.

Dividend income and capital gain distributions, if any, are recognized on the ex-dividend date, net of any foreign taxes withheld at source, if any.

Interest income is recorded daily on an accrual basis. All premiums and discounts are amortized/accreted for financial reporting purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

Non-cash dividends received in the form of stock are recorded as dividend income at fair value.

The State Street U.S. Core Equity Fund invests in real estate investments trusts ("REITs"). REITs determine the tax character of their distributions as a return of capital or capital gain. The Fund's policy is to record all REIT distributions initially as dividend income and re-designate the prior calendar year's to return of capital gains distributions at year end based on information provided by the REIT and/or SSGA FM estimates of such redesignations for which actual information has not yet been reported.

**Expenses** Certain expenses, which are directly identifiable to a specific Fund, are applied to the Fund that incurs such expenses. Other expenses which cannot be attributed to a specific Fund are allocated in such a manner as deemed equitable, taking into consideration the nature and type of expense and the relative net assets of the Fund.

**Distributions** The State Street Income Fund declares investment income dividends daily and pays them monthly. The State Street U.S. Core Equity Fund declares and pays dividends from investment income annually.

Net realized capital gains, if any, are distributed annually, unless additional distributions are required for compliance with applicable tax regulations. The amount and character of income and capital gains to be distributed are determined in accordance with applicable tax regulations which may differ from net investment income and realized gains recognized for U.S. GAAP purposes.

**4. Securities and Other Investments** 

**Delayed Delivery Transactions and When-Issued Securities** During the period ended March 31, 2026, the State Street Income Fund 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. The securities purchased on a delayed delivery or when-issued basis are identified as such in the State Street Income Fund's Schedule of Investments. The State Street Income Fund may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to such purchase commitments, the State Street Income Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. 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.

**To-Be-Announced Transactions** The State Street Income Fund may seek to obtain exposure to U.S. agency mortgage pass-through securities through the use of "to-be-announced" or "TBA transactions." "TBA" refers to a commonly used mechanism for the forward settlement of U.S. agency mortgage pass-through securities. In a TBA transaction, the buyer and seller decide on general trade parameters, such as agency, settlement date, coupon, and price.

The State Street Income Fund may use TBA transactions to "roll over" such agreements prior to the settlement date. This type of TBA transaction is sometimes known as a "TBA roll." In a TBA roll, the State Street Income Fund generally will sell the obligation to purchase the pools stipulated in the TBA agreement prior to the settlement date and will enter into a new TBA agreement for future delivery of pools of mortgage pass-through securities. The State Street Income Fund may also enter into TBA agreements and settle such transactions on the stipulated settlement date by accepting actual receipt or delivery of the pools of mortgage pass-through securities.

Default by or bankruptcy of a counterparty to a TBA transaction would expose the State Street Income Fund to possible loss because of adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA transaction. To minimize this risk, the State Street Income Fund will enter into TBA transactions only with established counterparties. The State Street Income Fund's use of "TBA rolls" may impact portfolio turnover, transaction costs and capital gain distributions to shareholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

**5. Derivative Financial Instruments**

**Futures Contracts** Each Fund may enter into futures contracts to meet a Fund's objectives. A futures contract is a standardized, exchange-traded agreement to buy or sell a financial instrument at a set price on a future date. Upon entering into a futures contract, a Fund is required to deposit with the broker, cash or securities in an amount equal to the minimum initial margin requirements of the clearing house. Securities deposited, if any, are designated on the Funds' Schedule of Investments and cash deposited, if any, is included in Net cash collateral on deposit with broker for future contracts and TBAs on the Statements of Assets and Liabilities. Subsequent payments are made or received by a Fund equal to the daily change in the contract value, accumulated, exchange rates, and or other transactional fees. The accumulation of those payments are recorded as variation margin receivable or payable with a corresponding offset to unrealized gains or losses. A Fund recognizes a realized gain or loss when the contract is closed.

Losses may arise if the value of a futures contract decreases due to unfavorable changes in the market rates or values of the underlying instrument during the term of the contract or if the counterparty does not perform under the contract. The use of futures contracts also involves the risk that the movements in the price of the futures contracts do not correlate the movement of the assets underlying such contracts.

For the period ended March 31, 2026, the State Street U.S. Core Equity Fund and the State Street Income Fund entered into futures contracts in order to equitize cash and manage exposure to interest rates, respectively.

**Credit Default Swaps** During the period ended March 31, 2026, the State Street Income Fund engaged in credit default swaps to manage credit risk. When the Fund is the buyer in a credit default swap contract, the Fund is entitled to receive the par (or other agreed upon) value (full notional value) of a referenced debt obligation (or basket of debt obligations) from the counterparty (or central clearing party ("CCP") in the case of a centrally cleared swap) to the contract if a credit event by a third party, such as a U.S. or foreign corporate issuer or sovereign issuer, on the debt obligation occurs. In return, the Fund pays the counterparty a periodic stream of payments over the term of the contract provided that no credit event has occurred. If no credit event occurs, the Fund loses its investment and recovers nothing. However, if a credit event occurs, the Fund receives full notional value for a referenced debt obligation that may have little or no value. When the Fund is the seller of a credit default swap, it receives a fixed rate of income throughout the term of the contract, provided there is no credit event. If a credit event occurs, the Fund is obligated to pay the notional amount of the swap and in certain instances take delivery of securities of the reference entity upon the occurrence of a credit event, as defined under the terms of that particular swap agreement. Credit events are contract specific but may include bankruptcy, failure to pay, restructuring, obligation acceleration and repudiation/moratorium. If the Fund is a seller of protection and a credit event occurs, the maximum potential amount of future payments that the Fund could be required to make would be an amount equal to the notional amount of the agreement. This potential amount would be partially offset by any recovery value of the respective referenced obligation, or net amount received from the settlement of a buy protection credit default swap agreement entered into by the Fund for the same referenced obligation. As the seller, the Fund may create economic leverage to its portfolio because, in addition to its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. The interest fee paid or received on the swap, which is based on a specified interest rate on a fixed notional amount, is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as realized gain upon receipt or realized loss upon payment. The Fund also records an increase or decrease to unrealized appreciation (depreciation) in an amount equal to the daily valuation. For centrally cleared swaps, the daily change in valuation is recorded as a receivable or payable for variation margin and settled in cash with the CCP daily. All upfront payments, if any, are amortized over the life of the swap as realized gains or losses. Those upfront payments that are paid or received, typically for non-centrally cleared swaps, are recorded as other assets or other liabilities, respectively, net of amortization. For financial reporting purposes, unamortized upfront payments, if any, are netted with unrealized appreciation or depreciation on swaps to determine the market value of swaps. The Fund segregates assets in the form of cash or liquid securities in an amount equal to the notional amount of the credit default swaps of which it is the seller. The Fund segregates assets in the form of cash or liquid securities in an amount equal to any unrealized depreciation of the credit default swaps of which it is the buyer, marked to market on a daily basis. Credit default swaps involve

greater risks than if the Fund had invested in the referenced debt obligation directly. If the Fund is a buyer of a credit default swap and no credit event occurs, the Fund will not earn any return on its investment. If the Fund is a seller of a credit default swap, the Fund's risk of loss may be the entire notional amount of the swap. Swaps may also subject the Fund to the risk that the counterparty to the transaction may not fulfill its obligation. In the case of centrally cleared swaps, counterparty risk is minimal due to protections provided by the CCP.

The following tables summarize the value of the Funds' derivative instruments as of March 31, 2026 and the related location in the accompanying Statements of Assets and Liabilities and Statements of Operations, presented by primary underlying risk exposure:

**Due to Custodian** In certain circumstances, the Funds may have cash overdrafts with the custodian due to expense payments, capital transactions, trading of securities, investment operations or derivative transactions. The Due to Custodian amount, if any, reflects cash overdrawn with State Street as custodian, who is an affiliate of the Funds.

**Other Transactions with Affiliates** Each Fund may invest in affiliated entities, including securities issued by State Street Corporation, affiliated funds, or entities deemed to be affiliates as a result of the Funds owning more than five percent of the entity's voting securities or outstanding shares. Amounts relating to these transactions during the period ended March 31, 2026 are disclosed in each Fund's Schedule of Investments.

**7. Trustees' Fees** 

The fees and expenses of the Trustees who are not "interested persons" of the Trust, as defined in the 1940 Act, ("Independent Trustees") are paid directly by the Funds. The Independent Trustees are reimbursed for travel and other out-of-pocket expenses in connection with meeting attendance and industry seminars.

**8. Investment Transactions**

Purchases and sales of investments (excluding in-kind transactions, TBA transactions, short term investments and derivative contracts) for the period ended March 31, 2026 were as follows:

---

**Redemption In-Kind** In accordance with guidelines described in the Funds' prospectus, a Fund may distribute portfolio securities rather than cash as payment for a redemption of Fund shares (in-kind redemption). For financial reporting purposes, a Fund recognizes a gain or loss on in-kind redemptions to the extent the value of the distributed securities on the date of redemption exceeds or is less than, respectively, the cost of those securities. Gains and losses realized on in-kind redemptions are not recognized for tax purposes and are reclassified from undistributed realized gain (loss) to paid-in capital. These reclassifications have no effect on net assets or NAV per share. The net realized in-kind gains or losses are disclosed in the Statements of Operations and the Statements of Changes in Net Assets.

During the period ended March 31, 2026, the State Street U.S. Core Equity Fund and the State Street Income Fund had redemptions in-kind that resulted in redemptions of $718,957,702 and $316,553,225 that were paid in securities, respectively.

During the year ended September 30, 2025, the State Street U.S. Core Equity Fund and the State Street Income Fund had redemptions in-kind that resulted in redemptions of $823,835,661 and $153,937,992 that were paid in securities, respectively.

**9. Income Tax Information**

The Funds have qualified and intend to continue to qualify as regulated investment companies under Subchapter M of the Internal Revenue Code of 1986, as amended. Each Fund will not be subject to the federal income taxes to the extent it distributes its taxable income, including any net realized capital gains, for each fiscal year. Therefore, no provision for federal income tax is required.

The Funds file federal and various state and local tax returns as required. No income tax returns are currently under examination. Generally, the federal returns are subject to examination by the Internal Revenue Service for a period of three years from date of filing, while the state returns may remain open for an additional year depending upon jurisdiction. As of September 30, 2025, SSGA FM analyzed the Funds' tax positions and does not believe there are any uncertain tax positions that would require recognition of a tax liability.

Distributions to shareholders are recorded on ex-dividend date. Income dividends and gain distributions are determined in accordance with income tax rules and regulations, which may differ from generally accepted accounting principles.

As of March 31, 2026, gross unrealized appreciation and gross unrealized depreciation of investments and other financial instruments based on cost for federal income tax purposes were as follows:

**10. Line of Credit**

The State Street Income Fund and other affiliated funds (each, a "Participant" and collectively, the "Participants") have access to $210 million of a $1.425 billion ($194.29 million of $1.36 billion prior to October 2, 2025) revolving credit facility provided by a syndication of banks under which the Participants may borrow to fund shareholder redemptions. This agreement expires in October 2026 unless extended or renewed.

The Participants are charged an annual commitment fee which is calculated based on the unused portion of the shared credit line. Commitment fees are allocated among each of the Participants based on relative net assets. Commitment fees are ordinary fund operation expenses. A Participant incurs and pays the interest expense related to its borrowing. Interest is calculated at a rate per annum equal to the sum of 1.00% plus the greater of the New York Fed Bank Rate and the one-month SOFR Rate.

The State Street Income Fund had no outstanding loans during the period ended March 31, 2026.

**11. Risks**

**Concentration Risk** As a result of a Fund's ability to invest a large percentage of its assets in obligations of issuers within the same country, state, region, currency or economic sector, an adverse economic, business or political development may affect the value of a Fund's investments more than if a Fund was more broadly diversified.

**Interest Rate Risk** The risk that fixed income securities will decline in value because of changes in interest rates. Bond prices generally rise when interest rates decline and generally decline when interest rates rise. Changes in governmental policy, including changes in central bank monetary policy, could cause interest rates to rise rapidly, or cause investors to expect a rapid rise in interest rates. This could lead to heightened levels of interest rate, volatility and liquidity risks for the fixed income markets generally and could have a substantial and immediate effect on the values of a Fund's investments.

**Credit Risk** Each Fund may be exposed to credit risk in the event that an issuer or guarantor fails to perform or that an institution or entity with which the Fund has unsettled or open transactions defaults.

**Market Risk** Each Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Funds are subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional, or global events such as war, acts of terrorism, the spread of infectious illness, such as COVID-19, or other public health issues, or other events could have a significant impact on a Fund and its investments.

New or escalation of hostilities in the Middle East region could disrupt energy production or transportation, including through key shipping routes, which may lead to increased volatility in energy and other commodity

prices. The extent and duration of these conflicts, and others around the world, are impossible to predict but could continue to be significant. Market disruption caused by these conflicts, and any countermeasures or responses thereto (including international sanctions, a downgrade in a country's credit rating, purchasing and financing restrictions, boycotts, tariffs, changes in consumer or purchaser preferences, cyberattacks and espionage) could continue to have severe adverse impacts on regional and/or global securities and commodities markets, including markets for oil and natural gas. These impacts may include reduced market liquidity, distress in credit markets, further disruption of global supply chains, increased risk of inflation, and limited access to investments in certain international markets and/or issuers. These developments and other related events could negatively impact Fund performance.

**12. Subsequent Events**

Management has evaluated the impact of all subsequent events on the Funds through the date on which the financial statements were available to be issued and has determined that there were no subsequent events requiring adjustment or disclosure in the financial statements.
