Ironwood Institutional Multi-Strategy Fund LLC

Management's Discussion of Fund Performance (Unaudited)

Investment Approach

Ironwood Institutional Multi-Strategy Fund LLC's ("IIMS" or the "Fund") investment objective is capital appreciation with limited variability of returns. IIMS seeks to achieve this objective by allocating capital to a select group of alternative asset managers and the investment funds they operate. The Fund primarily invests across four core hedge fund sectors: relative value, market neutral and hedged equity, event-driven, and distressed and credit securities. These sectors are described in more detail in the Fund's prospectus and audited financial statements.

Performance Overview

For the fiscal year ended April 30, 2024, Ironwood Institutional Multi-Strategy Fund LLC returned 8.52% net while the HFRI FOF: Conservative Index ("HFRI FOF") returned 7.46% for the same period.

Performance and Portfolio Discussion

Over the last twelve months, the primary macroeconomic drivers that shaped market and investor sentiment included decade-high interest rates, elevated inflation, a regional banking crisis, and escalating geopolitical tensions. Despite these top-down headwinds, both equity and bond markets responded with a broad-based rally at year-end 2023, due in large part to better-than-expected economic resilience and the prospect of multiple rate cuts in 2024. However, as of April 2024, previous rate cut expectations have since sharply moderated as inflation data has surprised to the upside and the labor market remains tight.

The Fund generated consistent returns throughout the fiscal year in an uncorrelated manner to both equity and bond markets; during the twelve months ended April 30, 2024, the Fund returned 8.52% net with an annualized standard deviation of 1.46% and a beta of 0.06 and 0.12 to the S&P 500 Total Return Index and Bloomberg U.S. Aggregate Bond Index, respectively. All four of the Fund's sectors were positive over the fiscal year, and the leading drivers of performance included Market Neutral and Hedged Equity and Relative Value. Looking ahead, while Ironwood is not subject to any formal diversification requirements, Ironwood will continue to seek to diversify its investments in underlying funds across sectors and strategies, while opportunistically seeking to take advantage of compelling opportunities.

At the end of the fiscal period, the Fund's exposure by sector was as follows: Relative Value (51%), Market Neutral and Hedged Equity (26%), Event Driven (14%), and Distressed and Credit Securities (6%).

Fund Performance

The graph below illustrates the growth of a hypothetical $50,000 investment in the Fund over the ten years ended April 30, 2024 compared to the HFRI FOF.

The table below presents the Fund's average annual total returns through the fiscal year ended April 30, 2024.

Return information is unaudited, estimated, and subject to change. Fund Returns shown are net of fees (including an advisory fee of 1.20% per annum) and expenses and reflect the reinvestment of dividends and other investment income. Fund Returns shown do not include any commissions or transaction charges that may be charged by certain broker-dealers upon investing in the Fund and do not reflect the deduction of taxes that an investor would pay on Fund distributions or the redemption of Fund units. Past performance is not indicative of future results. Depending on an investor's investment date, holding period, and other factors, an investor may have overall performance that underperforms or outperforms that reflected above.

Management's Discussion of Fund Performance (Unaudited)

Index and Statistical Definitions

Index performance is shown for illustrative purposes only and does not represent the performance of any specific investment. Index returns do not include expenses, fees or charges, which would lower performance. The indices are unmanaged and an investor cannot invest directly in an index. In reviewing the performance of the Fund, investors should not consider any of the indices presented herein to be performance benchmarks.

HFRI FOF: Conservative Index: The HFRI FOF: Conservative Index is an equal-weighted index representing funds of funds that invest with multiple managers focused on consistent performance and lower volatility via absolute return strategies. The Index includes funds of funds tracked by Hedge Fund Research, Inc. The Index is a proxy for the performance of the universe of conservative funds of funds focused on absolute return strategies. Returns are net of fees and are denominated in USD. SOURCE: HFR, Inc. www.HFR.com. The HFR Indices are being used under license from HFR Holdings, LLC, which does not approve of or endorse any of the products or the contents discussed in this these materials.

Bloomberg U.S. Aggregate Bond Index: The Bloomberg U.S. Aggregate Bond Index is a broad-based fixed income benchmark that measures the investment grade, U.S. dollar-denominated, fixed-rate taxable bond market. The index includes Treasuries, government-related and corporate securities, mortgage backed securities (agency fixed-rate pass-throughs), asset backed securities and commercial mortgage backed securities (agency and non-agency). For more information, please visit www.bloomberg.com/indices.

S&P 500 Index: The S&P 500 Index includes 500 leading companies in leading industries of the U.S. economy, capturing 75% coverage of U.S. equities. It is intended as an indicator of large-cap public U.S. equities. For more information, please visit www.standardandpoors.com.

Beta: Beta is the slope of the regression line. Beta measures the risk of a particular investment relative to the market as a whole (the "market" can be any index or investment you specify). It describes the sensitivity of the investment to broad market movements.

Correlation: Correlation measures the degree to which two financial variables, such as a particular investment and a benchmark index, move in relation to each other. High correlation implies that one variable tends to increase as the other variable increases, or vice versa. Low correlation implies that there is little-to-no linear relationship between the two variables.

Standard Deviation: Standard Deviation measures the degree of variation of returns around the mean (average) return. The higher the volatility of the investment returns, the higher the standard deviation will be. For this reason, standard deviation is often used as a measure of investment risk. All values are presented annualized.

Report of Independent Registered Public Accounting Firm

To the Members and the Board of Directors of Ironwood Institutional Multi-Strategy Fund LLC

Opinion on the Financial Statements

We have audited the accompanying consolidated statement of assets and liabilities of Ironwood Institutional Multi-Strategy Fund LLC (the "Fund"), including the consolidated schedule of investments, as of April 30, 2024, and the related consolidated statements of operations and cash flows for the year then ended, the consolidated statements of changes in net assets for each of the two years in the period then ended, the consolidated financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the consolidated financial position of the Fund at April 30, 2024, the consolidated results of its operations and its cash flows for the year then ended, the consolidated changes in its net assets for each of the two years in the period then ended and its consolidated financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements based on our audit. 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 audit 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 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 the Fund's internal control over financial reporting. As part of our audit, 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 audit included performing procedures to assess the risks of material misstatement of the financial statements, 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. Our procedures included confirmation of investments owned as of April 30, 2024, by correspondence with the investment managers or administrators of the investment funds or by other appropriate auditing procedures where replies from the investment managers or administrators of the investment funds were not received. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

We have served as the Fund's auditor since 2010.

Total return assumes a subscription of a unit in the Fund at the beginning of the year, a repurchase of the unit on the last day of the year, and the re-investment of all distributions during the year.

(c)

Ratios do not reflect the Fund's proportionate share of the expenses of the investm+ent funds.

(d)

Ratios do not reflect the Fund's proportionate share of the income and expenses of the investment funds.

(e)

The Fund's senior securities during this time period were comprised only of borrowings made pursuant to the Fund's credit agreements or note purchase agreements.

(f)

Calculated by subtracting the Fund's liabilities and indebtedness not represented by senior securities from the Fund's total assets, dividing the result by the aggregate amount of the Fund's senior securities representing indebtedness then outstanding, and multiplying the result by 1,000.

The above ratios and total return have been calculated for the Members taken as a whole. An individual Member's return and ratios may vary from these returns and ratios due to the timing of unit transactions.

Ironwood Institutional Multi-Strategy Fund LLC

Notes to Consolidated Financial Statements

Year Ended April 30, 2024

1. Organization

Ironwood Institutional Multi-Strategy Fund LLC (the "Fund") was organized under the laws of the state of Delaware as a limited liability company on August 25, 2010 and commenced operations on January 1, 2011. The Fund is registered under the U.S. Investment Company Act of 1940, as amended (the "1940 Act") as a closed-end, non-diversified management investment company. The Fund is also registered under the U.S. Securities Act of 1933, as amended (the "1933 Act"). The Fund currently complies, and intends to continue to comply with the requirements of Subchapter M of the U.S. Internal Revenue Code of 1986, as amended (the "Code"), as such requirements are described in Note 2.

The Fund's investment objective is capital appreciation with limited variability of returns. The Fund attempts to achieve this objective by allocating capital among a number of pooled investment vehicles. Each is managed by an independent investment manager pursuant to various alternative investment strategies across four sectors: relative value, market neutral and hedged equity, event-driven, and distressed and credit securities.

The Fund is a master fund in a master-feeder structure whereby Ironwood Multi-Strategy Fund LLC (the "Feeder Fund") invests substantially all of its assets in the Fund. As of April 30, 2024, the Feeder Fund owned 50.50% of the Fund's net assets. Other eligible investors (together with the Feeder Fund, "Members") in the Fund include high net worth individuals, foundations, pensions, and other institutions.

Ironwood Capital Management serves as the Fund's investment adviser (the "Adviser") and is responsible for providing day-to-day investment management services to the Fund, subject to the oversight of the Fund's Board of Directors (the "Board"). The Adviser is registered as an investment adviser with the U.S. Securities and Exchange Commission (the "SEC") under the U.S. Investment Advisers Act of 1940, as amended. The Adviser is also registered as a Commodity Pool Operator with the U.S. Commodity Futures Trading Commission and is a member of the National Futures Association. The Board has overall responsibility for monitoring and overseeing the Fund's investment program and its management and operations. The majority of the members of the Board are not "interested persons" (as defined by the 1940 Act) of the Fund or the Adviser.

The Fund utilizes the Bank of New York Mellon (the "Administrator" and "Custodian") as its independent administrator and custodian.

Notes to Consolidated Financial Statements (continued)

2. Significant Accounting Policies

Basis of Presentation

The following significant accounting policies are in conformity with U.S. generally accepted accounting principles ("U.S. GAAP"). Such policies are consistently followed by the Fund in the preparation of its consolidated financial statements. The consolidated financial statements are expressed in U.S. dollars.

The Fund is an investment company as described in Accounting Standards Codification ("ASC") Topic 946, Financial Services-Investment Companies ("ASC 946"), which defines investment companies and prescribes specialized accounting and reporting requirements for investment companies. The Fund follows the accounting and reporting guidance in ASC 946.

Use of Estimates

The preparation of these consolidated financial statements in conformity with U.S. GAAP requires the Adviser to make estimates and assumptions that affect the reported amounts and disclosures in the consolidated financial statements, including the estimated fair value of investments. Actual results could differ from those estimates.

Basis of Consolidation

The consolidated financial statements include the financial position and the results of operations of the Fund and its wholly owned subsidiary, Ironwood Multi-Strategy Fund Ltd. ("CFC"), a Cayman Islands controlled foreign corporation. CFC has the same investment objective as the Fund and is primarily used to invest in investment funds which do not allow U.S. entities to invest directly. As of April 30, 2024 and for the year then ended, no investment funds were held by the wholly owned subsidiary.

Net Asset Value Determination

The net asset value of the Fund is determined as of the close of business at the end of any fiscal period, generally monthly, in accordance with the valuation principles set forth below or as determined pursuant to policies established by the Board.

Portfolio Valuation

The Fund's portfolio valuation is subject to the requirements of the 1940 Act and SEC Rule 2a-5 ("Rule 2a-5"). As permitted by Rule 2a-5, the Board has appointed the Adviser as the Fund's valuation designee ("Valuation Designee"), subject to its oversight, with respect to the Fund's investments that do not have readily available market quotations. The Adviser, as Valuation Designee, is responsible for performing fair value determination of these investments in accordance with the requirements of Rule 2a-5, which includes selecting and consistently applying an appropriate valuation methodology.

Ironwood Institutional Multi-Strategy Fund LLC

Notes to Consolidated Financial Statements (continued)

The Fund's investments are valued at fair value in accordance with ASC Topic 820, Fair Value Measurements and Disclosures ("ASC 820"). See Note 4 for more information.

Cash

The Fund places its cash in accounts that are affiliated with the Administrator and the Custodian and, at times, such balances may be in excess of the Federal Deposit Insurance Corporation insurance limits. The Adviser monitors the financial condition of the Administrator and the Custodian and does not anticipate any losses from these counterparties.

Income and Expense Recognition

The Fund records investment transactions on a trade date basis and recognizes income and expenses on an accrual basis. Income, expenses, and realized and unrealized gains and losses are recorded monthly. Changes in the investment funds' fair values are included in net change in unrealized appreciation/depreciation on investments on the consolidated statement of operations. Realized gain (loss) from investments in investment funds is calculated using the specific identification methodology.

Income Taxes

The Fund currently complies, and intends to continue to comply with the requirements of Subchapter M of the Code applicable to Regulated Investment Companies ("RICs") and distributes substantially all of its taxable income to its Members. Therefore, no provision for federal income taxes is required. The Fund files tax returns with the U.S. Internal Revenue Service and state(s) as applicable. The Fund has concluded there are no significant uncertain tax positions that would require recognition in the consolidated financial statements as of April 30, 2024. If applicable, the Fund recognizes interest accrued related to liabilities for unrecognized tax in interest expense and penalties in other expenses on the consolidated statement of operations. The open tax years under potential examination vary by jurisdiction, but in general tax authorities can examine all tax returns filed for the last three tax years.

The Fund has a tax year that ends on April 30.

Dividend Reinvestment Plan

Each Member will have all income distributions and capital gains distributions automatically reinvested in additional units unless such Member specifically elects to receive all income distributions and capital gains distributions in cash.

Ironwood Institutional Multi-Strategy Fund LLC

Notes to Consolidated Financial Statements (continued)

3. Financial Instruments with Off-Balance Sheet Risk

In the normal course of business, the investment funds in which the Fund invests trade various financial instruments and enter into various investment activities with off-balance sheet risk. These include, but are not limited to, short selling activities, written option contracts, and swaps. The Fund's risk of loss in these investment funds is limited to the value of the Fund's interest in these investment funds as reported by the Fund.

4. Fair Value of Financial Instruments

ASC 820 provides for the use of net asset value (or its equivalent) as a practical expedient to estimate fair value of investments in investment funds, provided certain criteria are met. Accordingly, the Fund values its investments in investment funds at fair value, which is an amount equal to the sum of the Fund's proportionate interests in the investment funds, as determined from financial information provided by the respective administrators or investment managers of the investment funds. These fair values represent the amounts the Fund would receive if it were able to liquidate its investments in the investment funds as of the measurement date, prior to any early withdrawal charges, if applicable. Some values received are estimates, subject to subsequent revision by the respective administrators or investment managers. Values received are generally net of management fees and incentive fees or allocations payable to the investment funds' investment managers pursuant to the investment funds' operating agreements. The investment funds value their underlying investments in accordance with policies established by each investment fund, as described in each of their financial statements or offering memoranda.

The investment funds hold positions in readily marketable investments and derivatives that are valued at quoted market values and/or less liquid non-marketable investments and derivatives that are valued at estimated fair value. The mix and concentration of more readily marketable investments and less liquid non-marketable investments varies across the investment funds based on various factors, including the nature of their investment strategy. The Fund's investments in investment funds are subject to the terms and conditions of the respective operating agreements and offering memoranda.

The Adviser has designed ongoing due diligence processes with respect to investment funds, their administrators, and their investment managers. The Adviser assesses the quality of information provided and determines whether such information continues to be reliable or whether further investigation is necessary. Such investigation, as applicable, may require the Adviser to forego its normal reliance on the value provided and to independently determine the fair value of the Fund's interest in the investment fund.

The Adviser has designated a committee to oversee the valuation of the Fund's investments (the "Valuation Committee"). The Valuation Committee is comprised of senior personnel, the majority of whom are separate from the Fund's portfolio management team, and is responsible for developing written valuation policies and procedures, conducting periodic reviews of those policies and procedures, and evaluating the overall fairness and consistent application of the valuation policies and procedures. The Valuation Committee meets on a quarterly basis or more frequently as needed.

Ironwood Institutional Multi-Strategy Fund LLC

Notes to Consolidated Financial Statements (continued)

If no value is readily available from an investment fund or if a value supplied by an investment fund is deemed by the Valuation Committee not to be indicative of its fair value, the Valuation Committee would determine, in good faith, the fair value of the investment fund under procedures adopted by the Board and subject to Board oversight. Because of the inherent uncertainty of valuation, the fair values of the investment funds held by the Fund may differ significantly from the values that would have been used had a ready market for the investment funds been available. As of and for the year ended April 30, 2024, all investments in investment funds were valued using the values provided by the investment funds or their administrators.

Short-term investments consist of investments in money market funds valued at $148,086,016 as of April 30, 2024. These investments are valued using readily available market quotations at their respective net asset value per share and are categorized as Level 1 in the fair value hierarchy, as defined in ASC 820.

In accordance with U.S. GAAP, investments in investment funds that are valued at net asset value as a practical expedient are not required to be included in the fair value hierarchy. All investments in investment funds were valued at their respective net asset value as of April 30, 2024, and are excluded from the fair value hierarchy.

As of April 30, 2024, approximately 0.73% of the Fund's net assets were invested in investment funds that do not have set redemption timeframes but are liquidating investments and making distributions as underlying investments are sold. Additionally, approximately 5.75% of the Fund's net assets were invested in designated private investments maintained by the investment funds or in term vehicles, which do not have set redemption timeframes. The timing of when these investments will be liquidated is unknown.

The following is a summary of the Fund's investment sectors as of April 30, 2024.

Relative value strategies attempt to capture pricing anomalies between assets that for all economic purposes are identical. Relative value strategies capture these inefficiencies by utilizing a combination of assets including bonds, stocks, swaps, options, exchange traded funds, currencies, futures, etc. One such strategy is capital structure arbitrage which involves the purchase and short sale of different classes of securities of the same issuer where there is a relative mispricing between two classes of securities. An example of this strategy is the purchase of undervalued senior secured debt and the short sale of overvalued subordinated unsecured debt or common equity. Other examples of relative value strategies include fixed income arbitrage, relative value interest rates, convertible bond arbitrage, relative value energy, and quantitative strategies. Generally, investment funds within this sector require a 30 to 90 day notice period to redeem at the next available redemption date.

Ironwood Institutional Multi-Strategy Fund LLC

Notes to Consolidated Financial Statements (continued)

Market neutral and hedged equity strategies involve the purchase of a stock or basket of stocks that is relatively underpriced as well as selling short a stock or basket of stocks that is relatively overpriced. Depending on the manager's investment strategy, the determination of whether a stock is overpriced or underpriced can be made through fundamental analysis (a fundamental strategy) or by complex statistical models that examine numerous factors that affect the price of a stock (a quantitative strategy). The Adviser will utilize equity managers that target well-hedged and low net exposures and/or use a balanced approach to investing, i.e., they are short approximately the same dollar value of stocks they are long. Generally, investment funds within this sector require a 45 to 90 day notice period to redeem at the next available redemption date.

Event-driven strategies involve the assessment of how, when, and if specific transactions will be completed and the effect on corporations and financial assets. A common event-driven strategy is merger arbitrage (also called risk arbitrage). This involves the purchase of the stock of a target company involved in a potential merger and, in the case of a stock-for-stock offer, the short sale of the stock of the acquiring company. The target company's stock would typically trade at a discount to the offer price due to the uncertainty of the completion of the transaction. The positions may be reversed if the manager feels the acquisition may not close. This strategy aims to capture the spread between the value of the security at the close of the transaction and its discounted value at the time of purchase. Other examples of event-driven strategies and opportunities include corporate restructurings, spin-offs, operational turnarounds, activism, asset sales, and liquidations. Generally, investment funds within this sector require a 60 to 90 day notice period to redeem at the next available redemption date.

Distressed strategies involve the purchase or short sale of debt or equity securities of issuers experiencing financial distress. These securities may be attractive because of the market's inaccurate assessment of the issuer's future potential or the values and timing of recoveries. Managers may obtain voting rights or control blocks and actively participate in the bankruptcy or reorganization process while other investors may remain passive investors. Examples of distressed securities trades include bankruptcies, liquidations, post-restructured equities, structured credit, and balance sheet restructurings. Credit strategies involve a variety of strategies intended to exploit inefficiencies in the high-yield and related credit markets. Generally, investment funds within this sector require a 90 day notice period to redeem at the next available redemption date.

5. Investment Transactions

Total purchases of investment funds for the year ended April 30, 2024 were $278,581,479. Total redemptions from investment funds for the year ended April 30, 2024 were $248,702,806.

Ironwood Institutional Multi-Strategy Fund LLC

Notes to Consolidated Financial Statements (continued)

6. Members' Units

The stated minimum initial investment by Members is $50,000 and the minimum subsequent investment is $10,000. The Adviser may waive these minimums, but in no event will the initial investment be less than $25,000. Members may purchase units as of the first business day of the month.

Subscriptions received in advance and subscriptions received in advance from Ironwood Multi-Strategy Fund LLC represent the amounts received on or prior to April 30, 2024 for subscriptions with an effective date of May 1, 2024.

Foreside Fund Services, LLC acts as the distributor (the "Distributor") of the Fund's units. The Distributor has entered into, and may continue to enter into, selected dealer agreements with various brokers and dealers ("Selling Agents") that agree to participate in the distribution of the Fund's units. Neither the Fund nor the Distributor impose an initial sales charge. If a Member purchases units through a Selling Agent, the Selling Agent may directly charge the Member a transaction or other fees in such amount as the Selling Agent determines. Any such transaction or other fees charged by a Selling Agent is in addition to the subscription price for units and does not form a part of a Member's investment in the Fund.

The Board, in its sole and absolute discretion, may authorize the Fund to make a tender offer to repurchase Members' units (an "Offer"). In determining whether the Fund should make an Offer to repurchase units from Members, the Board will consider, among other things, the recommendation of the Adviser. The Adviser expects that it will recommend to the Board that the Fund make an Offer to repurchase units from Members semi-annually on June 30 and December 31. While there can be no guarantee that it will continue this practice, to date, the Fund has offered to repurchase 10 - 20% of its units at each of its June 30 and December 31 Offers.

As part of each Offer, Members of the Fund may request to tender units and immediately subscribe the resulting proceeds to the Feeder Fund. As part of the Feeder Fund's tender offers, Members of the Feeder Fund may request to tender units and immediately subscribe the resulting proceeds to the Fund. In these circumstances, the Fund and the Feeder Fund process the transactions without requiring the payment or receipt of cash. For the year ended April 30, 2024, the total amount of non-cash subscriptions was $27,761,174 and there were no non-cash redemptions for the year.

A 5% early repurchase fee is charged on repurchased units that have been held less than one year, payable to the Fund. The Board or the Adviser may waive the imposition of the early repurchase fee. For the year ended April 30, 2024, the Fund charged early repurchase fees of $7,256. Such amount is included in other income on the consolidated statement of operations.

In no event shall any Member have any liability for the repayment or discharge of debts and obligations of the Fund except to the extent provided by the Fund's prospectus or as required by law.

Ironwood Institutional Multi-Strategy Fund LLC

Notes to Consolidated Financial Statements (continued)

7. Advisory Fee, Related Party Transactions, and Other Expenses

In consideration of the advisory and other services provided by the Adviser to the Fund, the Fund pays the Adviser a monthly advisory fee (the "Advisory Fee") of 0.10% (1.20% per annum) of the Fund's month end net asset value. The Advisory Fee is an expense paid out of the Fund's assets and is computed based on the value of the net assets of the Fund as of the close of business on the last calendar day of each month, before adjustments for any repurchases effective on that day. The Advisory Fee is payable in arrears as of the last calendar day of the applicable fiscal quarter and is in addition to the asset-based management fees and incentive fees or allocations charged by the investment funds and indirectly borne by Members in the Fund. For the year ended April 30, 2024, the Fund incurred Advisory Fees of $58,693,647, of which $15,100,228 was payable to the Adviser as of April 30, 2024.

The Fund pays all investment expenses, including, but not limited to, brokerage commissions and all other costs of executing transactions, interest expense, commitment fees, custody fees, its share of expenses of the investment funds, including management fees to the investment managers of the investment funds (ranging from 0.00% to 3.50% of net asset value) and incentive fees or allocations to such investment managers (ranging from 0% to 40% of net profits). The Fund also pays all ongoing ordinary administrative and operational costs of the Fund, including (but not limited to) legal costs, audit and tax preparation fees, fees paid to the Administrator, fees paid to the regulatory and compliance administrator, risk monitoring fees, filing fees, insurance expense, fees paid to sub-transfer agencies, bank charges, and taxes. The Fund will also pay any extraordinary operating expenses. Among the Fund's operating expenses are certain costs that may be associated in part with the Feeder Fund that are not clearly allocable on a separate basis, such as joint vendor contracts. The Feeder Fund is the largest member of the Fund and as such bears a significant pro rata share of all expenses of the Fund.

The Adviser will bear all ongoing ordinary administrative and operational costs of the Adviser, including employees' salaries, office rent, travel costs, computer and equipment costs, telephone bills, office supplies, research and data costs, legal costs, accounting costs, filing costs, and communication expenses.

The Adviser has entered into an agreement with the Fund (the "Expense Limitation Agreement") whereby it has contractually agreed to waive its fees and/or reimburse the Fund's expenses to the extent necessary to ensure that the monthly expenses of the Fund (excluding taxes, brokerage commissions, interest expense and commitment fees incurred in connection with any credit facility, other transaction related expenses, custody fees, bank charges, any extraordinary expenses of the Fund, any acquired fund fees and expenses, and the Advisory Fee) will not exceed 0.020833% (0.25% per annum) of the Fund's net assets as of each month end during the term of the Expense Limitation Agreement (the "Expense Limitation"). The Fund will carry forward, for a period not to exceed 3 years from the date on which a waiver or reimbursement is made by the Adviser, any expenses in excess of the Expense Limitation and repay the Adviser such amounts; provided that the Fund is able to effect such reimbursement and remain in compliance with the Expense Limitation disclosed in the prospectus that was in effect at the time of the original waiver.

Ironwood Institutional Multi-Strategy Fund LLC

Notes to Consolidated Financial Statements (continued)

Eligible expenses were below the Expense Limitation and no eligible expenses were recaptured under the Expense Limitation Agreement during the year ended April 30, 2024. There are no amounts subject to potential future reimbursement to the Adviser.

Compensation to the independent directors for the year ended April 30, 2024 was $155,000.

As of April 30, 2024, directors, officers, and the Adviser and its employees held units in the Fund as follows:

		Units		Percent of Net Assets
Directors		1,377.09		0.03%
Officers		150.49		0.01%

9. Income Taxes

The Fund generally invests in investment funds organized outside the United States that are treated as corporations for U.S. tax purposes and are expected to be classified as passive foreign investment companies ("PFICs"). Certain PFICs provide information regarding the amount of U.S. taxable income and gain. For such PFICs, the Fund has made Qualified Electing Fund ("QEF") elections for tax purposes.

For other PFICs that do not provide information regarding taxable income and gain, the Fund has made mark-to-market ("MTM") elections which convert any unrealized gain to ordinary taxable income.

The Fund also invests in investment funds organized in the U.S. that are treated as partnerships for U.S. income tax purposes.

Net investment income (loss) and net realized gain (loss) from investments in investment funds may not be treated the same for financial statement and for U.S. tax purposes. Temporary book-tax differences result when the Fund holds an investment in an investment fund, and such temporary book-tax differences generally become permanent upon disposal of the investment fund.

As of April 30, 2024, the aggregate cost and related gross unrealized appreciation and depreciation for tax purposes of the Fund's investments were as follows:

Cost of investments for tax purposes		$	5,107,666,405
Gross tax unrealized appreciation		$	70,952,990
Gross tax unrealized depreciation			(74,442,622)
Net tax unrealized depreciation on investments		$	(3,489,632)

Permanent differences, due to deemed distributions attributable to redemptions of Units, resulted in the following reclassifications among the Fund's components of net assets as of April 30, 2024:

Accumulated losses		$	(4,273,407)
Paid-in capital			4,273,407

Distribution of Income and Gains

The Fund declares and pays dividends annually from net investment income. Net realized gains, if any, are distributed at least annually. Distributions from net realized gains for book purposes may include short-term capital gains, which are included as ordinary income for tax purposes.

Ironwood Institutional Multi-Strategy Fund LLC

Notes to Consolidated Financial Statements (continued)

10. Commitments

As of April 30, 2024, the Fund had unfunded capital commitments to investment funds of $199,579,387.

11. Indemnification

In the normal course of business, the Fund enters into contracts that provide general indemnifications and that contain a variety of representations and warranties. The Fund's maximum exposure in connection with these contracts is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, no claims have been made under these indemnities in the past, and while there can be no assurances in this regard, the Fund is not aware of any such claims that may be made in the future.

12. Subsequent Events

The Adviser has performed a subsequent events review and determined that there were no subsequent events which would have a significant impact on the Fund's financial position or results of operations.

Federal Tax Information (Information Unaudited)

The Fund is required by the Internal Revenue Code of 1986, as amended ("the Code"), to advise you about the federal tax status of dividends paid by the Company during the Company's fiscal year ended April 30, 2024: 1) 0.25% of ordinary income dividends paid during the year constitutes qualified dividend income in accordance with Section 854(b)(1)(B) of the Code, and 2) 0% of ordinary income dividends paid during the year are eligible for the corporate dividends received deduction provided under Section 243 of the Code in accordance with Section 854(b)(1)(A) of the Code.

(e)

(1) The Audit Committee has adopted an Audit and Non-Audit Services Pre-Approval Policy, which specifies the procedures and conditions under which services may be pre-approved. If the proposed service is not specifically included in the Pre-Approval Policy, it must be pre-approved on a case-by-case basis. The Audit Committee considers whether the proposed services would impair the auditor's independence and whether the auditor is in the best position to provide the most effective and efficient service. The Audit Committee may delegate pre-approval authority to one or more of its members. A member to whom such authority is delegated must report all approval decisions to the Audit Committee at its next scheduled meeting. The Audit Committee may not delegate to management its responsibility to pre-approve services to be performed by the Fund's independent auditor.

The following services are considered pre-approved by the Audit Committee for the period ending April 30, 2024: audits of the Fund required by regulatory or statutory bodies; audits of management assertions related to the effectiveness of internal controls over financial reporting as required under the Sarbanes-Oxley Act; services associated with SEC registration statements, periodic reports and other documents filed with the SEC; consultation on accounting or disclosure treatment of transactions or events; assistance in dealing with and responding to the SEC or any other regulatory agency on financial matters; tax compliance, including the preparation of federal, state, local and international tax returns; tax planning and advice.

(b) 0

(c) 100

(d) 0

(f)	The percentage of hours expended on the principal accountant's engagement to audit the Fund's financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant's full-time, permanent employees was less than fifty percent.

(g)

The aggregate non-audit fees billed by the Fund's accountant for services rendered to the Fund, and rendered to the Fund's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the Fund were $0 for the fiscal year ended April 30, 2024, and $0 for the fiscal year ended April 30, 2023.

(h)

The Fund's Audit Committee of the Board of Directors has considered whether the provision of non-audit services that were rendered to the Fund's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the Fund that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.

Item 12. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies.

The Proxy Voting Policies and Procedures of the Fund and its investment adviser are as follows:

The Fund invests in other private investment funds (the "Underlying Funds"), each managed by an independent investment adviser (collectively, the "Underlying Advisers"). As such, it is expected that proxies and consent requests received by Ironwood will deal with matters related to the operative terms and business details of such Underlying Funds. Ironwood is not responsible for, and these procedures are not applicable to, proxies received by Underlying Advisers (related to issuers invested in by the related Underlying Fund).

To the extent that the Fund receives notices or proxies from Underlying Funds (or to the extent the Fund receives proxy statements or similar notices in connection with any other portfolio securities), the Fund has delegated proxy voting responsibilities to Ironwood. Ironwood will vote proxies and respond to investor consent requests in the best interests of the Fund, as applicable, in accordance with Ironwood's Proxy Voting Policies and Procedures (the "Policies").

The Policies provide the following general guidelines for determining the best interests of the Fund:

(i) Ironwood will generally vote in favor of normal corporate housekeeping proposals including, but not limited to, the following:

(A) election of directors (where there are no related corporate governance issues);

(B) selection or reappointment of auditors; or

(C) increasing or reclassification of common stock.

(ii) Ironwood will generally vote against proposals that:

(A) make it more difficult to replace members of the issuer's board of directors or board of managers; and

(B) introduce unequal voting rights (although there may be regulatory reasons that would make such a proposal favorable to certain clients of Ironwood).

For proxies or consent requests addressing any other issues (which may include proposals related to fees paid to investment managers of underlying investment funds, redemption rights provided by underlying investment funds, investment objective modifications, etc.), Ironwood shall determine (which may be based upon the advice of external lawyers or accountants) whether a proposal is in the best interest of the Fund. In doing so, Ironwood will evaluate a number of factors which may include (but are not limited to): (i) the performance of the Underlying Fund in question; and (ii) a comparison of the proposed changes in terms to customary terms in the industry.

The Fund files Form N-PX, with its complete proxy voting record for the twelve months ended June 30, no later than August 31 of each year. Once filed, the Fund's Form N-PX are available: (i) without charge, upon request, by calling the Fund at (415)-777-2400; or (ii) by visiting the SEC's website (http://www.sec.gov).

(a)(2)(iv) Potential Conflicts of Interest

The following actual and potential conflicts of interest may arise in connection with the Portfolio Managers' management of the Fund's investments:

1)

Other Activities. Ironwood also provides investment advisory services to other investment funds that utilize substantially the same investment strategy as the Fund (the "Other Ironwood Funds"). The Fund has no interest in these activities. Ironwood and the investment professionals who, on behalf of Ironwood, provide investment advisory services to the Fund are engaged in substantial activities other than on behalf of the Fund, may have differing economic interests in respect of such activities, and may have conflicts of interest in allocating their time and activity between the Fund and the Other Ironwood Funds.

2)

Preferential Terms. Ironwood, its affiliates, or accounts other than the Fund managed by Ironwood or its affiliates may invest in Underlying Funds on terms more favorable than those available to the Fund, and, as investors in such Underlying Fund, may act in ways adverse to the interests of the Funds.

3)

Allocation of Investments with Underlying Funds Between the Fund and Other Ironwood Funds. Ironwood is also the investment adviser of the Other Ironwood Funds. Ironwood often selects Underlying Funds for investment by the Fund that are managed by Underlying Advisers that advise parallel funds (the "Underlying Parallel Funds") in which the Other Ironwood Funds may have made or may make an investment. In some cases, the Fund may invest in the same Underlying Funds as the Other Ironwood Funds. Conflicts of interest may arise with the allocation of investment transactions and opportunities, as well as in the amount or timing of when redemption notices are placed. The Fund may waive voting rights to address regulatory implications that might arise under the 1940 Act. The Fund and Ironwood have adopted policies and procedures regarding the allocation of investment opportunities, which generally require that investment opportunities be allocated among the Fund and Other Ironwood Funds in a manner that is fair, equitable and consistent with their fiduciary obligations to each.

4)

Proprietary Trading by Ironwood, the Underlying Funds and Their Principals. Ironwood, the Underlying Funds and their respective principals and employees may trade securities or other investments for their own accounts and may have actual or potential conflicts of interest with respect to investments made on behalf of the Fund or an Underlying Fund in which the Fund invests. Furthermore, certain principals and employees of Ironwood have made direct investments in Underlying Funds managed by Underlying Advisers and Ironwood's advisory clients have made investments in the same Underlying Funds or other pooled investment vehicles managed by such Underlying Advisers. Such proprietary trading may be in competition with the Fund and may be conducted at brokerage commission rates, if applicable, substantially lower than rates charged to the Fund.

(a)(3) Portfolio Manager Compensation Structure
