In addition, words such as “may,” “will,” “should,” “target,” “anticipate,” “believe,” “expect,” “plan,” “seek” and “intend” indicate a forward-looking statement, although not all forward-looking statements include these words. The forward-looking statements contained in this Quarterly Report on Form 10-Q involve risks and uncertainties. Our actual results could differ materially from those implied or expressed in the forward-looking statements for any reason, including:

●

changes in political, economic or industry conditions, the interest rate environment or conditions affecting the financial and capital markets, including the effects of inflation, trade policies and government regulation;

●

risks associated with possible disruption in our operations or the economy generally due to terrorism, natural disasters, epidemics or other events having a broad impact on the economy;

Although we believe that the assumptions on which these forward-looking statements are based are reasonable, any of those assumptions could prove to be inaccurate, and as a result, the forward-looking statements based on those assumptions also could be inaccurate. In light of these and other uncertainties, the inclusion of a projection or forward-looking statement in this Quarterly Report on Form 10-Q should not be regarded as a representation by us that our plans and objectives will be achieved. These forward-looking statements apply only as of the date of this Quarterly Report on Form 10-Q.

ISQ Open Infrastructure Company LLC

Series I

Notes to Consolidated Financial Statements (Unaudited)

1. ORGANIZATION

ISQ Open Infrastructure Company LLC (the “Company”) is a limited liability company that was formed in accordance with the laws of Delaware on January 15, 2025. The Company is a series limited liability company with series established pursuant to Sections 18-215 or 18-218 of the Delaware Limited Liability Company Act (the “LLC Act”). On March 13, 2025, the Company established two registered series of limited liability company interests, ISQ Open Infrastructure Company LLC –- Series I (“Series I”) and ISQ Open Infrastructure Company LLC –- Series II (“Series II” and together with Series I, “Series”). The purchase of shares of a Series of the Company is an investment only in that particular Series and not an investment in the Company as a whole. In accordance with the LLC Act, each Series is a separate series of segregated assets and liabilities and corresponding limited liability company interests of the Company.

Series I and Series II are intended to be treated as separate entities for U.S. federal income tax purposes with segregated assets and liabilities. Sections 18-215(c) and 18-218(c)(1) of the LLC Act provide that a Series established in accordance with Section 18-215(b) or 18-218 of the LLC Act, respectively, may carry on any lawful business, purpose or activity, other than the business of banking, and has the power and capacity to, in its own name, contract, hold title to assets (including real, personal and intangible property), grant liens and security interests, and sue and be sued. The Company intends for each Series to conduct its business and enter into contracts in its own name to the extent such activities are undertaken with respect to a particular Series and assets associated with a Series may be held, directly or indirectly, including in the name of such Series, in the name of the Company, through a nominee or otherwise. Under Delaware law, to the extent the records maintained for a Series account for the assets associated with such Series separately from the other assets of the Company or any other Series, the debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to such Series are segregated and enforceable only against the assets of such Series and not against the assets of the Company generally or any other Series.

Each of Series I and Series II will remain in existence until its certificate of registered series has been cancelled in the manner required by the LLC Act following Series I’s or Series II’s, as applicable, dissolution and the completion of the winding up of such Series in accordance with the Fourth Amended and Restated Limited Liability Company Agreement of the Company (the “LLC Agreement”), the applicable series agreement and Delaware law. The LLC Agreement and the applicable series agreement provides that Series I or Series II will be dissolved upon (a) the adoption of a resolution by the board of directors (the “Board”) approving the dissolution of Series I or Series II, as applicable, and the approval of such action by the controlling shareholder, (b) the operations of Series I or Series II, as applicable, ceasing to constitute legal activities under the LLC Act or any other applicable law (as determined by the Board), (c) the entry of a decree of judicial dissolution of a Series under Section 18-218(c)(11) of the LLC Act, or (d) the dissolution of the Company.

The Company intends to conduct its operations so that neither Series I or Series II is required to register as an “investment company” under the Investment Company Act of 1940, as amended (the “Investment Company Act”). The Company primarily seeks to manage Joint Ventures that own and control private companies, infrastructure assets and infrastructure-related assets located globally but with a focus on North America, Europe and selected growth economies in Asia and Latin America (the “Infrastructure Assets”) with the objective of generating attractive risk-adjusted returns consisting of both current income and long-term capital appreciation.

The Company expects to conduct a continuous private offering of the shares to (i) accredited investors (as defined in Regulation D under the U.S. Securities Act of 1933 (the “Securities Act”)) and (ii) in the case of shares sold outside the United States, to persons that are not “U.S. persons” (as defined in Regulation S under the Securities Act) in reliance on exemptions from the registration requirements of the Securities Act, including under Regulation D and Regulation S.

The Company is sponsored by I Squared Capital Advisors (US) LLC (together with its subsidiaries and affiliated entities, “I Squared”) and ~~expects~~will to benefit from I Squared’s infrastructure sourcing and portfolio management platform pursuant to a management agreement (the “Management Agreement”) ~~to be~~ , entered into with I Squared Capital Registered Advisor LLC (the “Manager”), aan ~~wholly~~affiliate ~~owned subsidiary~~ of I Squared, on September 2, 2025, to support the Company in managing its portfolio of Infrastructure Assets. As of ~~June~~September 30, 2025, the Company had no operations other than activities related to its organization and offering. ~~During~~Since the ~~three~~Funding ~~months~~Date, ~~then~~as ~~ended~~defined below, the Company ~~began~~has ~~incurring professional~~incurred professional fees in connection with its ongoing reporting obligations.

In pursuing its investment objective, Series I will invest substantially all of its assets in Series II. The portfolio of Series I will typically consist solely of Series II shares. Therefore, Series I’s investment results are expected to correspond directly to the investment results of Series II. Series II has the same business objective and strategy as Series I. For convenience of the reader, references to Series II’s investments also refer to Series I investments (vice versa), and references to the risks of investing in Series II also refer to the risks of investing in Series I (vice versa), except as otherwise provided. Series I and Series II are part of a master-feeder fund structure. The feeder fund, Series I, invests substantially all of its assets in the master fund, Series II, through the Blocker, as defined below.

On March 28, 2025 (the “Funding Date”), I Squared contributed $2,000 to Series I. Series I contributed $1,000 to Series II through a blocker, ISQ Open Infrastructure Holdings, L.P. (the “Blocker”), domiciled in the Cayman Islands. The Blocker is wholly owned by Series I and has therefore been consolidated.

2. SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting— The consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and are presented in United States dollars. The Company’s fiscal year end is December 31.

~~The~~ Series I consolidated financial statements ~~are~~ are prepared using the accounting and reporting guidance under Financial Accounting Standards Board Accounting Standards Codification (“FASB”) Accounting Standards Codification (“ASC”) 946, Financial Services—Investment Companies. Series I and Series II qualify as investment companies solely for accounting purposes and not for any other purpose. Series I and Series II are not registered, and are not required to be registered, as investment companies under the Investment Company Act. Series I and Series II follow the significant accounting policies described below.

Basis of Presentation— Series I and Series II are intended to be treated as distinct entities under the LLC Act and for U.S. federal income tax purposes, each with its own segregated assets, liabilities, and expenses. If any expenses are incurred on behalf of or for the benefit of either Series, the Manager will allocate those expenses among ~~the~~ Series based on the relative size of each Series’ investment in the relevant activity or entity, the net asset value of each Series, or another method the Manager, in good faith, deems fair and reasonable.

Basis of Consolidation— As provided under Regulation S-X and ASC 946, the Company will generally not consolidate its investments in a company other than a wholly owned investment company or controlled operating company whose business consists of providing services to Series I. Accordingly, Series I consolidated the financial position and results of operations of its wholly-owned subsidiary, the Blocker. All significant intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates— The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions, in particular the fair value of investments, that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the amounts of income and expenses during the reporting period. Management believes that the estimates utilized in preparing the consolidated financial statements are reasonable and prudent; however, actual results could differ from those estimates, and such differences could be material to Series I.

Cash and Cash Equivalents— Cash and cash equivalents include cash on hand, cash held in banks and highly liquid investments. ~~There~~As ~~were no cash equivalents as~~ of ~~June~~September 30, 2025, there were no cash equivalents.

Organizational and Offering Expenses— Organizational expenses are expensed as incurred. Organizational expenses consist of costs incurred to establish Series I and enable it legally to do business. Organizational expenses will be paid by the Manager, subject to potential recoupment as described in Note 3. For the three months ended June 30, 2025 and for the period from March 28, 2025 (Funding Date) to June 30, 2025, Series I incurred organizational expenses of $65,708 and $196,564, respectively, which were fully reimbursed by the Manager.

Offering expenses include registration fees and legal fees regarding the preparation of the general form of registration of securities. Offering expenses are accounted for as deferred costs until operations begin. Offering expenses are then amortized over the first twelve months of operations on a straight-line basis. For the period from March 28, 2025 (Funding Date) to June 30, 2025, Series I incurred offering expenses of $196,119.

Investments, At Fair Value— The investment valuation policy of Series I is to value its financial instruments at fair value. Series I records its investment in Series II at fair value based on its proportionate interest in the net assets of Series II. Valuation of assets held by Series II is discussed in Note 2 of Series II’s Notes to Financial Statements.

Investment in Series II— On a monthly basis, Series I records its proportionate share of the income, expenses, realized gains and losses and change in unrealized gains and losses of Series II. In addition, Series I accrues its own income and expenses. At June 30,2025, Series I owned 100% of the net assets of Series II. The performance of Series I is directly impacted by the performance of Series II. The notes to the Series II financial statements are attached to the Series I consolidated financial statements and are an integral part of these consolidated financial statements.

Income Taxes— Series I intends to operate so that it will qualify to be treated as a partnership for U.S. federal income tax purposes under the Internal Revenue Code. An entity that is treated as a partnership for U.S. federal tax purposes generally incurs no U.S. federal income tax liability. Instead, each partner is generally required to take into account its allocable share of items of income, gain, loss, deduction, or credit of the entity in computing its U.S. federal income tax liability, regardless of whether cash distributions are made. A partnership, such as each Series, may nonetheless be taxed as a corporation if it is a publicly traded partnership, unless it meets the qualifying income exception. The qualifying income exception applies with respect to a publicly traded partnership if (i) at least 90% of such partnership’s gross income for each taxable year consists of “qualifying income” and (ii) the partnership would not be required to register under the Investment Company Act if it were a U.S. corporation. Qualifying income includes certain interest income, dividends, real property rents, gains from the sale or other disposition of real property, and any gain from the sale or disposition of a capital asset or other property held for the production of income that otherwise constitutes qualifying income. Each Series is intended to be managed such that it will meet the qualifying income exception in each taxable year. If either Series were recharacterized as a corporation for federal income tax purposes by not meeting the qualifying income exception, the holders of interest in that Series would then be treated as stockholders in a corporation, and the Series would become taxable as a corporation for U.S. federal income tax purposes. Further, each Series would be subject to U.S. corporate income tax on its net taxable income. In addition, each Series intends to operate, in part, through subsidiaries that may be treated as corporations for U.S. and non-U.S. tax purposes and, therefore, may be subject to current and deferred U.S. federal, state and/or local income taxes at the subsidiary level.

Segment Reporting - The Company operates through a single operating and reporting segment with a primary objective of generating attractive risk-adjusted returns consisting of both current income and long-term capital appreciation. The chief operating decision maker (“CODM”) is comprised of the Company’s Chief Executive Officer and Chief Investment Officer (the “Principal Committee”) which assesses the performance and makes operating decisions of the Company on a consolidated basis. The CODM has concluded that the Company operates as a single operating segment because the Company has a single investment strategy against which the CODM assesses the Company’s performance. In addition to other metrics, the CODM uses net increase (decrease) in net assets resulting from operations as a key metric to assess the Company’s performance. As the Company’s investment operations comprise a single reporting segment, the segment assets are the same assets that are reported in the Consolidated Statement of Assets and Liabilities and significant segment expenses are the same as those listed in the Consolidated Statements of Operations.

Organizational and Offering Expenses— Organizational expenses are expensed as incurred. Organizational expenses consist of costs incurred to establish Series I and enable it legally to do business. Organizational expenses will be paid by the Manager, subject to potential recoupment as described in Note 3. For the three months ended September 30, 2025 and for the period from the Funding Date to September 30, 2025, Series I incurred organizational expenses of $89,042 and $285,606, respectively, which were fully reimbursed by the Manager.

Offering expenses include registration fees and legal fees regarding the preparation of the general form of registration of securities. Offering expenses are accounted for as deferred costs until operations begin. Offering expenses are then amortized over the first twelve months of operations on a straight-line basis. For the period from the Funding Date to September 30, 2025, Series I incurred offering expenses of $214,660.

Investments, At Fair Value— The investment valuation policy of Series I is to value its financial instruments at fair value. Series I records its investment in Series II at fair value based on its proportionate interest in the net assets of Series II. Valuation of assets held by Series II is discussed in Note 2 of Series II’s Notes to Consolidated Financial Statements.

Investment in Series II— On a monthly basis, Series I records its proportionate share of the income, expenses, realized gains and losses and change in unrealized gains and losses of Series II. In addition, Series I accrues its own income and expenses. At September 30, 2025, Series I indirectly owned 100% of the net assets of Series II. The performance of Series I is directly impacted by the performance of Series II. The notes to Series II consolidated financial statements are attached to Series I consolidated financial statements and are an integral part of these consolidated financial statements.

Income Taxes— Series I intends to operate so that it will qualify to be treated as a partnership for U.S. federal income tax purposes under the Internal Revenue Code. An entity that is treated as a partnership for U.S. federal tax purposes generally incurs no U.S. federal income tax liability. Instead, each partner is generally required to take into account its allocable share of items of income, gain, loss, deduction, or credit of the entity in computing its U.S. federal income tax liability, regardless of whether cash distributions are made. A partnership, such as each Series, may nonetheless be taxed as a corporation if it is a publicly traded partnership, unless it meets the qualifying income exception. The qualifying income exception applies with respect to a publicly traded partnership if (i) at least 90% of such partnership’s gross income for each taxable year consists of “qualifying income” and (ii) the partnership would not be required to register under the Investment Company Act if it were a U.S. corporation. Qualifying income includes certain interest income, dividends, real property rents, gains from the sale or other disposition of real property, and any gain from the sale or disposition of a capital asset or other property held for the production of income that otherwise constitutes qualifying income. Each Series is intended to be managed such that it will meet the qualifying income exception in each taxable year. If either Series were recharacterized as a corporation for federal income tax purposes by not meeting the qualifying income exception, the holders of interest in that Series would then be treated as stockholders in a corporation, and the Series would become taxable as a corporation for U.S. federal income tax purposes. Further, each Series would be subject to U.S. corporate income tax on its net taxable income. In addition, each Series intends to operate, in part, through subsidiaries that may be treated as corporations for U.S. and non-U.S. tax purposes and therefore may be subject to current and deferred U.S. federal, state and/or local income taxes at the subsidiary level.

The chief operating decision maker (“CODM”) is comprised of the Company’s Chief Executive Officer and Chief Investment Officer (the “Principal Committee”) which assesses the performance and makes operating decisions of the Company on a consolidated basis. The CODM has concluded that the Company operates as a single operating segment because the Company has a single investment strategy against which the CODM assesses the Company’s performance. In addition to other metrics, the CODM uses net increase (decrease) in net assets resulting from operations as a key metric to assess the Company’s performance. As the Company’s investment operations comprise a single reporting segment, the segment assets are the same assets that are reported in the Consolidated Statement of Assets and Liabilities and significant segment expenses are the same as those listed in the Consolidated Statements of Operations.

For the three months ended September 30, 2025 and for the period from the Funding Date to September 30, 2025, Series I issued such Shares for aggregate consideration of $22,000 and $24,000, respectively. The offer and sale of the Shares were exempt from the registration provisions of the Securities Act of 1933, as amended, by virtue of Section 4(a)(2), including Regulation D (for sales to accredited investors) and/or Regulation S (for sales to non-U.S. investors outside of the United States) thereunder.

Distributions

Beginning with the end of the first full calendar quarter in which the Shares are sold to non-affiliates of I Squared, the Company will seek to declare, accrue and pay quarterly distributions. However, there is no guarantee that Series I or Series II will pay quarterly distributions consistently and at a specific rate, or at all. There were no distributions declared for the period from the Funding Date to September 30, 2025.

Distribution Reinvestment Plan

The Company adopted a distribution reinvestment plan (the “DRIP”), in which cash distributions to shareholders will automatically be reinvested in additional whole and fractional shares attributable to the type of Shares that a shareholder owns unless and until an election is made on behalf of such participating shareholder to withdraw from the DRIP and receive distributions in cash. The number of Shares to be received when distributions are reinvested will be determined by dividing the amount of the distribution, net of any applicable withholding taxes, by the Company’s or a Series’ NAV per share as of the end of the prior month. Shares will be distributed in proportion to Series and types of Shares held by the shareholder under the DRIP. There will be no sales load charges on Shares issued to a shareholder under the DRIP.

As of September 30, 2025, the Company had not issued any Shares under the DRIP.

Share Redemption Program

The Company offers a share redemption plan pursuant to which, on a quarterly basis, shareholders may request that we redeem all or any portion of their Shares. The Company may redeem fewer Shares than have been requested in any particular quarter to be redeemed under the Company’s share redemption plan, or none at all, in the Board’s discretion at any time. We expect that the Company will conduct quarterly Share redemptions (each, a “Share Redemption”) for up to 5.0% of the Company’s aggregate NAV per calendar quarter (measured using the average aggregate NAV attributable to shareholders as of the end of the immediately preceding calendar quarter), without duplication. Aggregate NAV will be reflective of Series I NAV which consists of all the underlying assets of Series II.

5. COMMITMENTS AND CONTINGENCIES

The Company and Series were not subject to any litigation nor were the Company and Series aware of any material litigation threatened against it.

Indemnifications

Under the Company’s LLC Agreement and organizational documents, members of each Series’ Board, the Manager, I Squared, and their respective affiliates, directors, officers, representatives, agents and employees are indemnified against all liabilities unless these persons’ actions constitute actual fraud or willful misconduct. In the normal course of business, the Company (on behalf of each Series) enters into contracts that contain a variety of representations and that provide general indemnifications. Each Series’ maximum liability exposure under these arrangements is unknown, as future claims that have not yet occurred may be made against either Series.

~~5. SUBSEQUENT EVENTS~~11

~~Management~~ ~~has~~6. ~~evaluated~~FINANCIAL and determined that there have been no subsequent events through August 14, 2025, the date these consolidated financial statements were available to be issued, that require recognition or disclosure in such consolidated financial statements, except as disclosed in Note 3.HIGHLIGHTS

8As of September 30, 2025, Series I has not commenced investment operations or generated revenues. Activities to date relate to organization, offering, and financing. All expenses were fully supported by the Manager under the Expense Limitation and Reimbursement Agreement. Accordingly, the total return, net expense ratio, and net investment income (loss) ratios are all 0%.

7. SUBSEQUENT EVENTS

Management has evaluated subsequent events through the filing of this Quarterly Report on Form 10-Q and determined to disclose the following subsequent events and transactions.

ISQ Open Infrastructure Company LLC (the “Company”) is a limited liability company that was formed in accordance with the laws of Delaware on January 15, 2025. The Company is a series limited liability company with series established pursuant to Sections 18-215 or 18-218 of the Delaware Limited Liability Company Act (the “LLC Act”). On March 13, 2025, the Company established two registered series of limited liability company interests, ISQ Open Infrastructure Company LLC—Series I (“Series I”) and ISQ Open Infrastructure Company LLC—Series II (“Series II” and together with Series I, “Series”). The purchase of shares of a Series of the Company is an investment only in that particular Series and not an investment in the Company as a whole. In accordance with the LLC Act, each Series is a separate series of segregated assets and liabilities and corresponding limited liability company interests of the Company.

The Company is sponsored by I Squared Capital Advisors (US) LLC (together with its subsidiaries and affiliated entities, “I Squared”) and ~~expects~~will to benefit from I Squared’s infrastructure sourcing and portfolio management platform pursuant to a management agreement (the “Management Agreement”) ~~to be~~ entered into with I Squared Capital Registered Advisor LLC (the “Manager”), aan ~~wholly~~affiliate ~~owned subsidiary~~ of I Squared, on September 2, 2025, to support the Company in managing its portfolio of Infrastructure Assets. As of ~~June~~September 30, 2025, the Company had no operations other than activities related to its organization and offering. ~~During~~Since the ~~three~~Funding ~~months~~Date, ~~then~~as ~~ended~~defined below, the Company ~~began~~has ~~incurring professional~~incurred professional fees in connection with its ongoing reporting obligations.

On March 28, 2025 (the “Funding Date”), Series I contributed $1,000 to Series II through a blocker, ISQ Open Infrastructure Holdings, L.P. (the “Blocker”), domiciled in the Cayman Islands. ~~As of June 30, 2025, no shares have been issued by Series II.~~

As of ~~June~~September 30, 2025, Series II had neither ~~purchased~~ purchased nor contracted to purchase any Infrastructure Assets or other assets.

2.	SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting— The ~~financial~~consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and are presented in United States dollars. The Company’s fiscal year end is December 31.

~~The~~ Series II consolidated financial statements are ~~prepared~~ prepared using the accounting and reporting guidance under Financial Accounting Standards Board Accounting Standards Codification (“FASB”) Accounting Standards Codification (“ASC”) 946, Financial Services—Investment Companies. Series I and Series II qualify as investment companies solely for accounting purposes and not for any other purpose. Series I and Series II are not registered, and are not required to be registered, as investment companies under the Investment Company Act. Series I and Series II follow the significant accounting policies described below.

Basis of Consolidation— As provided under Regulation S-X and ASC 946, Series II will generally not consolidate its investments in a company other than a wholly owned investment company or controlled operating company whose business consists of providing services to Series II. Accordingly, Series II consolidated the financial position and results of operations of its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates— The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions, in particular the fair value of investments, that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at at the date of the consolidated financial statements and the amounts of income and expenses during the reporting period. Management believes that the estimates utilized in preparing the consolidated financial statements are reasonable and prudent; however, actual results could differ from those estimates, and such differences could be material to Series II.

~~Cash and Cash Equivalents— Cash and cash equivalents include cash on hand, cash held in banks and highly liquid investments. There were no cash equivalents as of June 30, 2025.~~19

~~Organizational~~Cash and ~~Offering~~Cash ~~Expenses~~Equivalents— ~~Organizational~~ ~~expenses~~Cash ~~are expensed as incurred. Organizational expenses consist of costs incurred to establish Series II~~ and ~~enable~~cash equivalents itinclude ~~legally~~cash toon ~~do business. Organizational expenses will be paid by the Manager~~hand, ~~subject~~cash toheld ~~potential recoupment as described~~ in ~~Note~~banks ~~3. For the three months ended June 30, 2025~~ and ~~for~~highly ~~the~~liquid ~~period~~investments. ~~from~~As ~~March~~of ~~28,~~September ~~2025 (Funding Date) to June~~ 30, 2025, Series II ~~incurred~~held ~~organizational expenses~~cash equivalents of $~~590~~686,~~533 and $1,657,772, respectively, which were fully reimbursed by the Manager~~000.

14Organizational and Offering Expenses— Organizational expenses are expensed as incurred. Organizational expenses consist of costs incurred to establish Series II and enable it legally to do business. Organizational expenses will be paid by the Manager, subject to potential recoupment as described in Note 3. For the three months ended September 30, 2025 and for the period from the Funding Date to September 30, 2025, Series II incurred organizational expenses of $817,209 and $2,474,981, respectively, which were fully reimbursed by the Manager.

Offering expenses include registration fees and legal fees regarding the preparation of the general form of registration of securities. Offering expenses are accounted for as deferred costs until operations begin. Offering expenses are then amortized over the first twelve months of operations on a straight-line basis. For the period from ~~March~~the ~~28, 2025 (~~Funding Date) to ~~June~~September 30, 2025, Series II incurred offering expenses of $1,~~411~~561,~~303~~778.

Investments, at Fair Value— ASC 820, Fair Value Measurement, defines fair value, establishes a framework for measuring fair value in accordance with U.S. GAAP and expands disclosures about fair value. Series II recognizes and accounts for its assets (including the Infrastructure Assets) at fair value. The fair value of the assets does not reflect transaction costs that may be incurred upon disposition of the assets.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity for disclosure purposes.

Assets and liabilities recorded at fair value on the Consolidated Statement of Assets and Liabilities are categorized based upon the level of judgment associated with the inputs used to measure their value. Hierarchical levels, as defined under U.S. GAAP, are directly related to the amount of subjectivity associated with the inputs to fair valuations of these assets and liabilities, and are as follows:

Level 1— inputs are observable market inputs that reflect quoted prices for identical securities in active markets that the entity has the ability to access at the measurement date.

Level 2— inputs are observable market inputs other than quoted prices for identical assets in active markets the entity has the ability to access at the measurement date.

Level 3— inputs are unobservable markets inputs, for example, inputs derived through extrapolation or interpolation that are not able to be corroborated by observable market data.

A significant decrease in the volume and level of activity for the asset or liability is an indication that transactions or quoted prices may not be representative of fair value because in such market conditions there may be increased instances of transactions that are not orderly. In those circumstances, further analysis of transactions or quoted prices is needed, and an adjustment to the transactions or quoted prices may be necessary to estimate fair value.

Income Taxes— Series II intends to operate so that it will qualify to be treated as a partnership for U.S. federal income tax purposes under the Internal Revenue Code. An entity that is treated as a partnership for U.S. federal tax purposes generally incurs no U.S. federal income tax liability. Instead, each partner is generally required to take into account its allocable share of items of income, gain, loss, deduction, or credit of the entity in computing its U.S. federal income tax liability, regardless of whether cash distributions are made. A partnership, such as each Series, may nonetheless be taxed as a corporation if it is a publicly traded partnership, unless it meets the qualifying income exception. The qualifying income exception applies with respect to a publicly traded partnership if (i) at least 90% of such partnership’s gross income for each taxable year consists of “qualifying income” and (ii) the partnership would not be required to register under the Investment Company Act if it were a U.S. corporation. Qualifying income includes certain interest income, dividends, real property rents, gains from the sale or other disposition of real property, and any gain from the sale or disposition of a capital asset or other property held for the production of income that otherwise constitutes qualifying income. Each Series is intended to be managed such that it will meet the qualifying income exception in each taxable year. If either Series were recharacterized as a corporation for federal income tax purposes by not meeting the qualifying income exception, the holders of interest in that Series would then be treated as stockholders in a corporation, and the Series would become taxable as a corporation for U.S. federal income tax purposes. Further, each Series would be subject to U.S. corporate income tax on its net taxable income. In addition, each Series intends to operate, in part, through subsidiaries that may be treated as corporations for U.S. and non-U.S. tax purposes and, therefore, may be subject to current and deferred U.S. federal, state and/or local income taxes at the subsidiary level.

1520

Segment Reporting - — The Company operates through a single operating and reporting segment with a primary objective of generating attractive risk-adjusted returns consisting of both current income and long-term capital appreciation. The chief operating decision maker (“CODM”) is comprised of the Company’s Chief Executive Officer and Chief Investment Officer (the “Principal Committee”) which assesses the performance and makes operating decisions of the Company on a consolidated basis. The CODM has concluded that the Company operates as a single operating segment because the Company has a single investment strategy against which the CODM assesses the Company’s performance. In addition to other metrics, the CODM uses net increase (decrease) in net assets resulting from operations as a key metric to assess the Company’s performance. As the Company’s investment operations comprise a single reporting segment, the segment assets are the same assets that are reported in the Consolidated Statement of Assets and Liabilities and significant segment expenses are the same as those listed in the Consolidated Statements of Operations.

3. ~~RELATED~~NOTES ~~PARTY CONSIDERATIONS~~PAYABLE

Promissory Notes

On September 2, 2025, Series II issued unsecured promissory notes (the “Promissory Notes”) with a cumulative principal balance of $858,000. The Promissory Notes are reported at amortized cost and are reflected on Series II’s Consolidated Statement of Assets and Liabilities. The Promissory Notes pay interest on the principal balances at a rate of 12.4% per annum, payable semi-annually in arrears, with a legal maturity date of September 2, 2055. However, the Manager intends to repay the Promissory Notes prior to the legal maturity and is currently amortizing upfront costs associated with the Promissory Notes over a period of three years. Amortized amounts are included within interest and financing expenses on Series II’s Consolidated Statements of Operations.

4.	RELATED PARTY CONSIDERATIONS

Management Agreement

Expense Limitation and Reimbursement Agreement

The Company, on behalf of each Series, ~~entered~~ entered into an Expense Limitation and Reimbursement Agreement (the “Expense Limitation Agreement”) with the Manager on August 11, 2025, pursuant to which the Manager ~~agrees~~agreed to ~~forego~~forgo an amount of its monthly management fee and/or pay, absorb or reimburse certain expenses of the Company (and in turn each Series), to the extent necessary through and including June 30, 2026, so that, for any fiscal year, the Company’s annual Specified Expenses (as defined below) do not exceed 0.75% of the Company’s net assets as of the end of each calendar month. The Company, on behalf of each Series, ~~agrees~~agreed to carry forward the amount of any ~~foregone~~forgone management fee and/or expenses paid, absorbed or reimbursed by the Manager, when and if requested by the Manager, within five years from the end of the month in which the Manager waived or reimbursed such fees or expenses (“Excess Expenses”) and to reimburse the Manager in the amount of such Excess Expenses as promptly as possible, on a monthly basis, but only if and to the extent that Specified Expenses plus any recoupment do not exceed 0.75% of the Company’s net assets at the end of each calendar month. The Manager iswill be permitted to recapture a Specified Expense in the same year it is incurred. This arrangement iswill not be permitted to be terminated prior to June 30, 2026 without the Board’s consent. “Specified Expenses” is defined to include all expenses incurred in the business of the Company and ~~the~~each Series, including organizational and offering costs and any costs associated with the transfer of a warehoused Infrastructure Asset to the Company, with the exception of (i) the management fee, (ii) the performance participation allocation, (iii) the servicing fee, (iv) Infrastructure Asset level expenses, (v) brokerage costs or other investment-related out-of-pocket expenses, including with ~~respect~~ respect to unconsummated transactions, in each case, accrued on or after the Company acquires its first Infrastructure Asset(s) (the “Initial Close”), (vi) dividend/interest payments (including any dividend payments, interest expenses, commitment fees, or other expenses related to any leverage incurred by the Company), (vii) taxes, (viii) ordinary corporate operating expenses (including costs and expenses related to hiring, retaining, and compensating employees, officers and directors of the Company) accrued on or after the Initial Close, (ix) certain insurance costs and (x) extraordinary expenses (as determined in the sole discretion of the Manager).

5.	SHAREHOLDERS’ EQUITY

Distributions

Distribution Reinvestment Plan

The Company adopted a distribution reinvestment plan (the “DRIP”), in which cash distributions to shareholders will automatically be reinvested in additional whole and fractional shares attributable to the type of Shares that a shareholder owns unless and until an election is made on behalf of such participating shareholder to withdraw from the DRIP and receive distributions in cash. The number of Shares to be received when distributions are reinvested will be determined by dividing the amount of the distribution, net of any applicable withholding taxes, by the Company’s or a Series’ NAV per share as of the end of the prior month. Shares will be distributed in proportion to the Series and types of Shares held by the shareholder under the DRIP. There will be no sales load charges on Shares issued to a shareholder under the DRIP.

As of September 30, 2025, the Company had not issued any Shares under the DRIP.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion should be read in conjunction with the financial statements of each Series and notes thereto appearing in this Quarterly Report on Form 10-Q and the financial statements of each Series included in the Form 10. In addition to historical data, this discussion contains forward-looking statements about our business, operations and financial performance based on current expectations that involve risks, uncertainties and assumptions. Our actual results may differ materially from those in this discussion as a result of various factors, including but not limited to those discussed in “Part I, Item 1A. Risk Factors” in the Form 10.

Overview

We were formed as a Delaware limited liability company on January 15, 2025. The Company is sponsored by I Squared and indirectly benefits from I Squared’s asset sourcing, operations, and portfolio management capabilities.

We are a series limited liability company with series established or formed, as applicable, pursuant to Sections 18-215 or 18-218 of the Delaware Limited Liability Company Act (the “LLC Act”). The purchase of Shares of a Series of the Company is an investment only in that particular Series and not an investment in the Company as a whole. In accordance with the LLC Act, each Series is a separate series of limited liability company interests in the Company and not a separate legal entity.

Each of Series I and Series II were formed on March 13, 2025, as a registered series of the Company. Each of Series I and Series II will remain in existence until its certificate of registered series has been cancelled in the manner required by the LLC Act following Series I’s or Series II’s, as applicable, dissolution and the completion of the winding up of such Series in accordance with the Fourth Amended and Restated Limited Liability Company Agreement, as amended from time to time (the “LLC Agreement”), the applicable series agreement and Delaware law. The LLC Agreement and the applicable series agreement provide that Series I or Series II will be dissolved upon (a) the adoption of a resolution by the applicable Board approving the dissolution of Series I or Series II, as applicable, (b) the operations of Series I or Series II, as applicable, ceasing to constitute legal activities under the LLC Act or any other applicable law (as determined by the applicable Board), (c) the entry of a decree of judicial dissolution of a Series under Section 18-218(c)(11) of the LLC Act, or (d) the dissolution of the Company.

We have no operating history and were formed to own, control and provide capital to private companies, infrastructure assets and infrastructure-related assets located globally but with a focus on North America, Europe and selected growth economies in Asia and Latin America. Our principal office is located at 600 Brickell Avenue, PH, Miami, Florida 33131 and our telephone number is (786) 693-5739.

Our business objective is to primarily achieve long-term capital appreciation as well as current income for Shareholders generally by owning and, in most cases, controlling and managing Infrastructure Assets with the objective of generating attractive risk-adjusted returns consisting of both current income and long-term capital appreciation (the “Joint Ventures”) through which we will hold, directly or indirectly, majority and/or primarily controlling stakes in Infrastructure Assets and to a lesser extent, Joint Ventures that own influential yet non-controlling stakes in Infrastructure Assets. We may also provide financing in relation to certain infrastructure projects. The establishment of the Company reflects I Squared’s commitment to acquiring Infrastructure Assets. Notwithstanding the foregoing, we may also hold non-controlling stakes in one or more Joint Ventures.

We expect that, in the ordinary course, our control-oriented acquisitions of Infrastructure Assets and loans made to a specific infrastructure project or, to a lesser extent, our other strategic investments in Infrastructure Assets, will make up approximately 80% of our assets (with no more than 30% of our assets made up of Joint Ventures and Infrastructure Assets located in countries that are not members of the Organization for Economic Co-operation and Development (the “OECD”)).

Additionally, we expect that up to 20% of our assets will consist of certain liquid asset classes, including, but not limited to, cash and cash equivalents, U.S. Treasury securities, U.S. government agency securities, municipal securities, other sovereign debt, investment grade credit and other investments including high-yield credit, asset-backed securities, mortgage-backed securities, collateralized loan obligations, leveraged loans and/or debt of companies or assets (which may include (i) securities or loans for the Infrastructure Assets and/or (ii) funds invested in any of the foregoing managed by I Squared, its affiliates or a third-party manager) (collectively, the “Liquidity Portfolio”) in order to provide us with income, to facilitate capital deployment and to provide a potential source of liquidity. These types of liquid assets may exceed 20% of our assets at any given time due to new subscriptions, Shareholder participation in our share redemption program, distributions from, or dispositions of, Infrastructure Assets or for other reasons as our Manager determines. We have significant liquidity requirements, and adverse market and economic conditions may adversely affect our sources of liquidity, which could materially and adversely affect our business operations. In addition to the target of 20% for our Liquidity Portfolio, we intend to abide by certain other guidelines on our overall portfolio construction. Any investments into blind pools or publicly traded equity securities will not be considered part of the Liquidity Portfolio and thus will not be counted against the up to 20% target we have set for the Liquidity Portfolio.

We intend to operate our business in a manner such that neither Series will be defined as an investment company, as that term is used under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

Results of Operations

From January 15, 2025 (date of formation) through ~~June~~September 30, 2025, we were in our organizational period, had not commenced our principal operations and were focused on our formation and the Form 10. Our Form 10 automatically became effective on June 13, 2025. We will be dependent upon the proceeds from the Company’s continuous private offering of its Series’ Shares on a monthly basis (the “Private Offering”) in order to conduct our business. We intend to acquire Infrastructure Assets with the capital received from our Private Offering and any indebtedness that we may incur in connection with such activities.

Income

We plan to generate income primarily from our long-term ownership and control of Joint Ventures and Infrastructure Assets and, to a lesser extent, investments in our Liquidity Portfolio, which may consist of dividend income, interest income, and net realized gains or losses and net change in unrealized appreciation or depreciation.

Expenses

Management Fee

Pursuant to the management agreement with the Manager (the “Management Agreement”), the Manager is entitled to receive the management fee (the “Management Fee”), which shall be reduced by the Offsetable Fees (as defined below), as applicable, from the Company. The Management Fee will be paid by Series II and indirectly borne by Series I through its indirect investment in Series II.

The Management Fee is payable monthly in arrears in an amount equal to (i) 0.75% per annum for Class F-S Shares, Class F-D Shares, Class F-I Shares, Class F-J Shares, Class F-S_TEShares, Class F-D_TEShares, Class F-I_TEShares and Class F-J_TE Shares (together with Class F-S Shares, Class F-D Shares, Class F-I Shares, Class F-J Shares, Class F-S_TEShares, Class F-D_TEShares and Class F-I_TE Shares, the “Founder Shares”), and (ii) 1.25% per annum for Class S Shares, Class D Shares, Class I Shares, Class J Shares, Class S_TE Shares, Class D_TE Shares, Class I_TE Shares and Class J_TE Shares of the month-end net asset value (“NAV”) attributable to the Shares, before giving effect to any accruals for the Management Fee, ongoing shareholder servicing fees of 0.85% of NAV per annum for Class F-S Shares, Class S Shares, Class F-S_TE Shares and Class S_TE Shares, shareholder servicing fees of 0.50% of NAV per annum of Class F-J Shares, Class F-J_TE Shares, Class J Shares and Class J_TE Shares and shareholder servicing fees of 0.25% for Class F-D Shares, Class D Shares, Class F-D_TE Shares and Class D_TE Shares (the “Servicing Fee”), the Performance Participation Allocation (defined below), share redemptions for that month, any distributions and without taking into account any taxes (whether paid, payable, accrued or otherwise) of any intermediate entity through which we indirectly acquire, hold, provide financing with respect to, or dispose of any one or more Infrastructure Assets (each, an “Intermediate Entity” and together “Intermediate Entities”), as determined in the good faith judgment of the Manager. Such Management Fee is calculated based on our transactional NAV, which is used to determine the price at which we sell and redeem our Shares. With respect to the Founder Shares, the Management Fee is payable monthly in arrears in an amount equal to 0.75% per annum for the Founder Shares (the “Management Fee Rate”) and will increase to 1.25% per annum after the first 36 months in which the Founder Shares are offered measured from the date of commencement of the initial offering period (the first six (6) months of the Private Offering). The Manager, in its sole discretion, may agree to waive all or a portion of the Management Fee, or to agree to a reduced/rebated Management Fee Rate, with respect to any particular Shareholder or financial intermediary. The Class E Shares and Class E_TE Shares will not bear a Management Fee. To avoid duplication, Series I Shares will bear their proportional share of the Management Fee indirectly based on their proportional interest in the same class of Series II Shares directly subject to such Management Fee.

In addition to the fees paid to the Manager, we will pay all other costs and expenses of our operations, including compensation of our employees and non-investment professional employees of the Manager or I Squared, directors, custodial expenses, leveraging expenses, transfer agent expenses, legal fees, expenses of independent auditors, expenses of our periodic redemptions, expenses of preparing, printing and distributing offering documents, Shareholder reports, notices, proxy statements and reports to governmental agencies and taxes, if any.

The Manager or any of its affiliates or employees is expected to receive transaction, director’s, management, monitoring, break-up, and other similar fees or compensation in connection with the Company, its Infrastructure Assets and prospective Infrastructure Assets (other than any (i) reimbursement for Operating Expenses (as defined below) initially borne by the Manager or any of its affiliates, (ii) fees, compensation or other payments received directly or indirectly by the Manager or any of its affiliates with respect to any co-investment arrangement or any other I Squared Vehicles organized or managed by the Manager or any of its affiliates, (iii) fees received directly or indirectly from or in respect to strategic or third-party investors not otherwise attributable to the Company, including, without limitation, origination fees and (iv) fees, costs and expenses related to the provision of products and services by I Squared Service Providers (such fees, the “Offsetable Fees”)). The Company’s pro rata portion of the Offsetable Fees will be applied to reduce the Management Fee otherwise payable by the Company.

Performance Participation Allocation

The performance participation allocation payable to I Squared (the “Performance Participation Allocation”) is equal to 12.5% of the Total Return attributable to Investor Shares subject to a 5.0% annual Hurdle Amount and a High Water Mark with a 100% Catch-Up (each term defined herein). Such allocation will be measured and allocated or paid annually and accrued monthly (subject to pro-rating for partial periods). Such Performance Participation Allocation is calculated based on our transactional NAV, which is used to determine the price at which we sell and redeem our Shares. The Class E Shares and Class E_TE Shares will not bear any Performance Participation Allocation, and as a result, it is an expense specific only to Investor Shares at the rates specified herein, which will result in the dilution of Investor Shares in proportion to the fees charged to different types of Investor Shares. To avoid duplication, Series I Shares will bear their proportional share of the Performance Participation Allocation indirectly based on their proportional interest in the same class of Series II Shares directly subject to such Performance Participation Allocation.

Specifically, promptly following the end of each Reference Period (as described below), I Squared is allocated a Performance Participation Allocation in an amount equal to:

First, if the Total Return with respect to Investor Shares for the applicable period exceeds the sum, with respect to such relevant type of Shares, of (i) the Hurdle Amount for that period and (ii) the Loss Carryforward Amount (any such excess, “Excess Profits”), 100% of such Excess Profits until the total amount allocated to I Squared equals 12.5% of the sum of (x) the Hurdle Amount for that period and (y) any amount allocated to I Squared with respect to such type of Shares pursuant to this clause (any such amount, the “Catch-Up”); and

Second, to the extent there are remaining Excess Profits, 12.5% of such remaining Excess Profits.

I Squared will also be allocated a Performance Participation Allocation with respect to all Investor Shares that are redeemed in connection with redemptions of Shares in an amount calculated as described above with the relevant period being the portion of the Reference Period for which such Shares were outstanding, and proceeds for any such Share redemptions will be reduced by the amount of any such Performance Participation Allocation. Such Performance Participation Allocation is calculated based on the transactional NAV.

We expect Series II to pay the Performance Participation Allocation to I Squared. I Squared may elect to receive the Performance Participation Allocation in cash, Class E Shares and/or shares, interests or other forms of beneficial ownership in any Intermediate Entities. If the Performance Participation Allocation is paid in Class E Shares, such Shares may be redeemed at I Squared’s or its affiliate’s request and are subject to the redemption limitations of our quarterly share redemption program. I Squared intends to only request redemption of the Initial Capital Commitment (as defined below) following the earlier of (i) two years from the date the Company acquires its first Seed Asset(s) or (ii) such time the Company’s NAV exceeds $750 million; provided that such redemption requests may be accepted only after all redemption requests from unaffiliated shareholders have been fulfilled. I Squared intends to initially elect to receive the Performance Participation in Class E Shares. To align its economic interests with those of Shareholders, I Squared intends to delay the timing for when it will receive cash proceeds in respect of the Performance Participation Allocation. I Squared will give Shareholders at least one calendar quarter’s notice prior to making significant changes in the manner in which I Squared expects to receive its Performance Participation Allocation.

“Total Return” with respect to any Shares for any period since the end of the prior Reference Period shall equal the sum of: (i) all distributions accrued or paid (without duplication) on such Investor Shares outstanding at the end of such period since the beginning of the then-current Reference Period; plus (ii) the change in aggregate NAV of such Investor Shares since the beginning of the Reference Period before giving effect to (x) changes resulting solely from the proceeds of issuances of the Investor Shares, (y) any allocation/accrual to the Performance Participation Allocation and (z) applicable expenses for the Servicing Fee (including any payments made to the Company generally or the Series for payment of such expenses).

For the avoidance of doubt, the calculation of the Total Return will (i) include any appreciation or depreciation in the NAV of Investor Shares issued during the then-current Reference Period, (ii) treat any withholding tax on distributions paid by or received by the Company generally or any Series as part of the distributions accrued or paid on Investor Shares, (iii) exclude the proceeds from the initial issuance of such Shares and (iv) exclude any taxes (whether paid, payable, accrued or otherwise) of any Intermediate Entities, and may be calculated without taking into account certain deferred tax liabilities of such intermediate entities, as determined in the good faith judgment of the Manager.

“Hurdle Amount” for any period during a Reference Period means that amount that results in a 5% annualized internal rate of return on the NAV of the Investor Shares outstanding at the beginning of the then-current Reference Period and all Investor Shares issued since the beginning of the then-current Reference Period, calculated in accordance with recognized industry practices and taking into account the timing and amount of all distributions accrued or paid (without duplication) on all such Shares but excluding applicable expenses for the Servicing Fee.

The ending NAV of Investor Shares used in calculating the internal rate of return will be calculated before giving effect to any allocation/accrual to the Performance Participation Allocation and applicable expenses for the Servicing Fee. For the avoidance of doubt, the calculation of the Hurdle Amount for any period will exclude any Investor Shares redeemed during such period, which will be subject to the Performance Participation Allocation upon redemption as described above.

Except as described in the definition of “Loss Carryforward Amount” below, any amount by which the Total Return falls below the Hurdle Amount will not be carried forward to subsequent periods.

I Squared will not be obligated to return any portion of the Performance Participation Allocation paid due to the subsequent performance of the Company.

“Loss Carryforward Amount” shall initially equal zero and shall cumulatively increase by the absolute value of any negative annual Total Return and decrease by any positive annual Total Return; provided, that the Loss Carryforward Amount shall at no time be less than zero and provided further that the calculation of the Loss Carryforward Amount will exclude the Total Return related to any Investor Shares redeemed during the applicable Reference Period, which will be subject to the Performance Participation Allocation upon redemption as described above. For the avoidance of doubt, with respect to Shares redeemed during the applicable Reference Period, the Loss Carryforward Amount shall not include amounts that would have been attributable to such redeemed Shares had such Shares not been redeemed during the applicable Reference Period. The effect of the Loss Carryforward Amount is that the recoupment of past annual Total Return losses will offset the positive annual Total Return for purposes of the calculation of the Performance Participation Allocation. This is referred to as a “High Water Mark.”

“Reference Period” means the applicable year beginning on October 1 and ending on September 30 of the next succeeding year; provided, that the initial Reference Period shall be the period from July 1, 2025, to September 30, 2026.

Servicing Fees

The Company pays the applicable selling agents (“Selling Agents”) ongoing servicing fees (a) of 0.85% of NAV per annum for Class F-S Shares, Class S Shares, Class F-S_TE Shares and Class S_TE Shares, (b) of 0.50% for Class F-J Shares, Class J Shares, Class J_TE Shares and Class F-J_TEShares and (c) of 0.25% for Class F-D Shares, Class D Shares, Class F-D_TE Shares and Class D_TE Shares, accrued and payable monthly. Such Servicing Fees are calculated based on the transactional NAV. To avoid duplication, Class F-S_TE Shares, Class S_TE Shares, Class J_TE Shares, Class F-J_TEShares, Class F-D_TE Shares and Class D_TE Shares will bear their proportional share of the Servicing Fee indirectly based on their proportional interest in the same class of Series II Shares directly subject to such Servicing Fee.

The Class I Shares, Class F-I Shares, Class E Shares, Class I_TE Shares, Class F-I_TE Shares and Class E_TE Shares do not bear Servicing Fees. In certain cases, the Servicing Fee may be paid to one or more placement support agents (each a “Placement Support Agent”) engaged by the Company to assist the Company’s engagement of placement agents and other financial intermediaries in selling Shares and then remitted to the applicable Selling Agent. The Company may also pay for certain sub-transfer agency, platform, sub-accounting and administrative services outside of the Servicing Fee.

Administration

SS&C GIDS, Inc. serves as the administrator (the “Administrator”) and accounting agent. Pursuant to the administration agreement, the Administrator is responsible for generally managing the administrative affairs of the Company. The Administrator is entitled to receive a monthly fee based on the monthly value of the Company’s net assets, subject to a minimum annual fee, plus out-of-pocket expenses.

Organizational and Offering Expenses

The Company will bear all fees, costs and expenses incurred in connection with the organization of the Company, its pro rata share of fees, costs and expenses incurred with the organization of any Intermediate Entities and all fees, costs and expenses incurred in connection with the offering of the Shares, including, without limitation, related legal and accounting fees, printing costs, expenses associated with initial registrations, or any similar regime in other jurisdictions, travel, accommodation and other out-of-pocket expenses (collectively, the “Organizational and Offering Expenses”).

The Company will reimburse the Manager or its affiliates for the Organizational and Offering Expenses incurred prior to the commencement of operations of the Company subject to the Expense Limitation Agreement discussed herein (including legal, accounting, audit, printing, mailing, subscription processing and filing fees and expenses, due diligence expenses of participating broker-dealers supported by detailed and itemized invoices, costs in connection with preparing sales materials, design and website expenses, fees and expenses of the Company and/or the Series), to the extent necessary so that, for any fiscal year, the Company’s annual Specified Expenses (defined below) do not exceed 0.75% of the Company’s net assets as of the end of each calendar month.

Expense Limitation and Reimbursement Agreement

The Company, on behalf of of each Series, entered into an Expense Limitation and Reimbursement Agreement (the “Expense Limitation Agreement”) with ~~the~~ the Manager on August 11, 2025, pursuant to which the Manager ~~agrees~~agreed to ~~forego~~forgo an amount of its monthly Management Fee and/or pay, absorb or reimburse certain expenses of the Company (and in turn each Series), to the extent necessary through and including June 30, 2026, so that, for any fiscal year, the Company’s annual Specified Expenses (as defined below) do not exceed 0.75% of the Company’s net assets as of the end of each calendar month. The Company, on behalf of each Series, ~~agrees~~agreed to carry forward the amount of any ~~foregone~~forgone management fee and/or expenses paid, absorbed or reimbursed by the Manager, when and if requested by the Manager, within five years from the end of the month in which the Manager waived or reimbursed such fees or expenses (“Excess Expenses”) and to reimburse the Manager in the amount of such Excess Expenses as promptly as possible, on a monthly basis, but only if and to the extent that Specified Expenses plus any recoupment do not exceed 0.75% of the Company’s net assets at the end of each calendar month. The Manager ~~is permitted~~will be permitted to recapture a Specified Expense in the same year it is incurred. This arrangement iswill not be permitted to be terminated prior to June 30, 2026, without the Board’s consent. “Specified Expenses” is defined to include all expenses incurred in the business of the Company and the Series, including organizational and offering costs and any costs associated with the transfer of a warehoused Infrastructure Asset to the Company, with the exception of (i) the management fee, (ii) the performance participation allocation, (iii) the servicing fee, (iv) Infrastructure Asset level expenses, (v) brokerage costs or other investment-related out-of-pocket expenses, including with respect to unconsummated transactions, in each case, accrued on or after the Company acquires its first Infrastructure Asset(s) (the “Initial Close”), (vi) dividend/interest payments (including any dividend payments, interest expenses, commitment fees, or or other expenses related to any leverage incurred by the Company), (vii) taxes, (viii) ordinary corporate operating expenses (including costs and expenses related to hiring, retaining, and compensating employees, officers and directors of the Company) accrued on or after the Initial Close, (ix) certain insurance costs and (x) extraordinary expenses (as determined in the sole discretion of the Manager).

The Company, on behalf of each Series, ~~intends~~agreed ~~to agree~~ that its obligations under the Expense Limitation Agreement shall survive termination of the Expense Limitation Agreement. Further, upon dissolution, liquidation, sale of substantially all of the assets of the Company or termination of the Management Agreement, including termination of the Management Agreement by the Company, the Company ~~intends~~agreed ~~to agree~~ first to reimburse the Manager any amounts previously reimbursed by the Manager to the Company under the Expense Limitation Agreement in excess of the total Management Fee that would have otherwise been due to the Manager by the Company.

(w) fees, costs, expenses and compensation for (i) the employees of the Manager or its affiliates (including, but not limited to, salary, benefits and bonus which may be in the form of Performance Participation Allocation or similar incentive equity (as applicable)) and (ii) tax services (e.g., tax compliance, tax oversight and tax structuring), legal, hedging and currency management and transfer pricing services to the Company generally or any Series in each case as such fees, costs, expenses and compensation are allocable to the Company generally or any Series, as applicable, and at rates believed by the Manager to be fair to the Company generally and/or such Series, as applicable, and commercially reasonable, related to oversight functions and support services provided by the employees of the Manager, I Squared or its affiliates arising from, or incurred in connection with, the Company’s (generally) or any Series’ reporting, accounting, administration and valuations;

and (y) the allocable share of the Broken Deal Expenses of the Company generally or any Series. In determining the amount of Operating Expenses that may be fairly allocable to the Company generally, any Series and to any I Squared Vehicles that may participate in Joint Ventures with the Company generally or any Series, the Manager and its affiliates will take into account such factors as they deem appropriate, including, for example, capital of the Company generally, the applicable Series and applicable I Squared Vehicles, the amount of capital historically held or remaining in a particular holding or similar holdings, the aggregate NAV of the Company generally, the applicable Series and applicable I Squared Vehicles and the percentage of similar acquisitions in which the Company generally, the applicable Series or applicable I Squared Vehicles have historically participated. For the avoidance of doubt, any fees, costs and expenses related to the provision of products and services within the definition of Operating Expenses that are provided by I Squared Service Providers will be borne by the Company generally and/or the Series. Each Series will pay or otherwise bear its proportionate portion of the foregoing payments, fees, costs, expenses and other liabilities (for the avoidance of doubt, including any applicable value added tax) or obligations resulting from, related to, associated with, arising from or incurred in connection with the Company generally and/or operations. The Company will bear any extraordinary expenses it may incur, including any litigation expense.

2329

Hedging Activities

The Company may, but is not obligated to, engage in hedging transactions for the purpose of efficient portfolio management. The Manager may review the Company’s hedging policy from time to time depending on movements and projected movements of relevant currencies and interest rates and the availability of cost-effective hedging instruments for the Company at the relevant time.

With respect to any potential financings, general increases in interest rates over time may cause the interest expense associated with the Company’s borrowings to increase and the value of the Company’s fixed income investments to decline. The Company may seek to stabilize its financing costs as well as any potential decline in the Company’s assets by entering into derivatives, swaps or other financial products in an attempt to hedge its interest rate risk.

The Company may enter into foreign exchange hedging arrangements to manage foreign currency exchange rate risk on its non-U.S. dollar denominated securities or to facilitate the settlement of foreign currency denominated Infrastructure Asset transactions. These hedging instruments are used to reduce the Company’s exposure to fluctuations in exchange rates that may impact the value of its investments and transactions. The fair value of such instruments is typically marked-to-market on a regular basis, with changes in value recognized by the Company as unrealized gains or losses. Upon settlement or closure of the hedging position, the Company recognizes a realized gain or loss equal to the difference between the value at the inception of the hedge and the value at its conclusion.

Foreign exchange hedging activities involve elements of market risk beyond the amounts recognized in the Company’s financial statements. The Company’s primary risk related to hedging is the risk of an unfavorable change in the foreign exchange rate underlying the hedging instrument. Additional risks may arise from the potential inability of counterparties to meet the terms of their agreements. By using derivative instruments, the Company is exposed to counterparty credit risk, which is the risk that derivative counterparties may not perform in accordance with contractual provisions. The Company’s exposure to credit risk from counterparty non-performance is limited to the unrealized gains inherent in such transactions that are recognized in the Company’s financial statements.

Liquidity and Capital Resources

I Squared made an initial capital contribution of $2,000 in cash, in exchange for its member interest in Series I. On September 2, 2025, Series II issued unsecured promissory notes with a cumulative principal balance of $858,000 and Series I sold 880 Shares of $25 each to third party investors for an aggregate consideration of $22,000. The Company may issue Class E Shares to I Squared in connection with the Company’s acquisition of additional assets in the future. I Squared currently holds all of the Company’s outstanding interests in the form of a controlling limited liability company interest in each of Series I and II but does not otherwise own any Shares in either Series.

We expect to generate cash primarily from (i) the net proceeds of our continuous Private Offering, (ii) any financing arrangements we may enter into in the future and (iii) any future offerings of our equity or debt securities. Also see “Expense Limitation and Reimbursement Agreement” above. We believe that cash provided by such means will be sufficient to satisfy our anticipated cash requirements for the next twelve months and foreseeable future.

Our primary use of cash will be for (i) acquisition of Infrastructure Assets, (ii) the cost of operations (including the Management Fee and Performance Participation Allocation), (iii) debt service of any borrowings, and (iv) periodic redemptions, including under any share redemptions or tender offers.

Additionally, I Squared will commit to investing at least $15 million in the Company and other vehicles managed by the Manager (the “Initial Capital Commitment”).

Cash Flows

On March 28, 2025 (the “Funding Date”), I Squared contributed $2,000 to Series I. Series I contributed $1,000 to Series II through a blocker, ISQ Open Infrastructure Holdings, L.P. (the “Blocker”), domiciled in the Cayman Islands. The Blocker is wholly owned by Series I and has therefore been consolidated. ~~As of June 30, 2025, no shares have been issued by Series I or by Series II.~~

As of September 30, 2025, we had not declared or paid any distributions.

Critical Accounting Estimates

Below is a discussion of the accounting policies that management believes are critical to understanding our historical and future performance. We consider these policies critical because they involve significant judgments and assumptions and require estimates about matters that are inherently uncertain and because they are important for understanding and evaluating our reported financial results. Our accounting policies have been established to conform with Generally Accepted Accounting Principles in the United States of America (GAAP). The preparation of the consolidated financial statements in accordance with U.S. GAAP requires management to use judgments in the application of such policies. These judgments will affect our reported amounts of assets and liabilities and our disclosure of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. With different estimates or assumptions, materially different amounts could be reported in our consolidated financial statements. Additionally, other companies may utilize different estimates that may impact the comparability of our results of operations to those of companies in similar businesses.

Valuation of Company Assets

The fair value of all Infrastructure Assets will ultimately be determined by the Manager in accordance with the Company’s valuation policies and procedures approved by the Board. It will, in certain circumstances, be the case that the valuation of an Infrastructure Asset may not reflect the price at which the Infrastructure Asset is ultimately sold, and the difference between the valuation and the ultimate sale price could be material. The valuation methodologies used to value any Infrastructure Assets will involve subjective judgments and projections and may, in certain circumstances, not be accurate. Valuation methodologies will also involve assumptions and opinions about future events, which may or may not turn out to be correct. Valuation methodologies may permit reliance on a prior period valuation of particular Infrastructure Assets. Ultimate realization of the value of an asset depends to a great extent on economic, market and other conditions beyond the Manager’s control. There will be no retroactive adjustment in the valuation of any Infrastructure Asset, the price at which Shares were purchased or sold by Shareholders or redeemed by the Company, as applicable, the Management Fee or the Performance Participation Allocation to the extent any valuation proves to not accurately reflect the realizable value of an asset in the Company. The valuation of Infrastructure Assets will affect the amount and timing of the Performance Participation Allocation payable to I Squared and the amount of the Management Fee payable to the Manager. The valuation of investments of I Squared Vehicles will, in certain circumstances, affect the decision of potential Shareholders to subscribe for Shares. Similarly, the valuation of the Company’s Infrastructure Assets will, in certain circumstances, affect the ability of I Squared to form and attract capital to I Squared Vehicles. As a result, there may be circumstances in which the Manager is incentivized to make more speculative acquisitions of Infrastructure Assets, seek to deploy capital in Infrastructure Assets at an accelerated pace, hold Infrastructure Assets longer and/or the Manager is incentivized to determine valuations that are higher than the actual fair value of Infrastructure Assets. In particular, given that the Management Fee and the Performance Participation Allocation will be dependent on the valuation of illiquid assets, which will be determined by the Manager, the Manager could be incentivized to value the assets higher than if the Management Fee were not based on the valuation of such assets. The foregoing conflicts arising from valuation matters will not necessarily be resolved in favor of the Company, and Shareholders may not be entitled to receive notice or disclosure of the occurrence of these conflicts.

Recent Accounting Pronouncements

There were no accounting pronouncements issued during the three months ended ~~June~~September 30, 2025 that are expected to have a material impact on our financial statements included in in this Quarterly Report on Form 10-Q.

Off-Balance Sheet Arrangements

We currently have no off-balance sheet arrangements that are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Contractual Obligations

See “—Results of Operations” above for our contractual obligations and commitments with payments due subsequent to ~~June~~September 30, 2025.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There was no material change to our market risks during the three months ended ~~June~~September 30, 2025. We had no significant operations as of ~~June~~September 30, 2025. When we commence our principal operations, we expect that our primary market risk exposure will be to changes in Infrastructure Asset fair values, as well as credit risk and market risk with respect to use of derivative financial instruments along with interest rate risk with respect to our indebtedness. As of ~~June~~September 30, 2025, we did not use any derivative financial instruments and had no indebtedness. The Manager will be responsible for the oversight of risks to our business.

Changes in Fair Value

All of our Infrastructure Assets will be reported at fair value. Net changes in the fair value of Infrastructure Assets impact the net increase or decrease in net assets resulting from operations in our statements of operations. We estimate that a decrease in the fair value of Infrastructure Assets generally may result in a change in the amount of net increase or decrease in net assets resulting from operations, regardless of whether the Infrastructure Asset was valued using observable market prices or management estimates with significant unobservable pricing inputs.

Exchange Rate Risk

We may hold Infrastructure Assets denominated in currencies other than the U.S. dollar. Those Infrastructure Assets may expose us to the risk that the value of the Infrastructure Assets will be affected by changes in exchange rates between the Company’s functional currency and the currency in which the Infrastructure Assets are made.

We expect that our primary exposure to exchange rate risk will relate to movements in the value of exchange rates between the U.S. dollar and other currencies in which our Infrastructure Assets are denominated (including euros), net of the impact of foreign exchange hedging strategies, if any.

Credit Risk

Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. If the fair value of a derivative contract is positive, the counterparty will owe us, which creates credit risk for us. If the fair value of a derivative contract is negative, we will owe the counterparty and, therefore, do not have credit risk. We will seek to minimize the credit risk in derivative instruments by entering into transactions with high-quality counterparties, and monitoring the associated credit exposure.

Interest Rate Risk

Changes in credit markets and in particular, interest rates, can impact investment valuations and may have offsetting results depending on the valuation methodology used. Additionally, low interest rates related to monetary stimulus and economic stagnation may also negatively impact expected returns on all investments, as the demand for relatively higher return assets increases and supply decreases.

With respect to our proposed business operations, general increases in interest rates over time may cause the interest expense associated with our borrowings to increase and the value of our fixed income investments to decline. Conversely, general decreases in interest rates over time may cause the interest expense associated with our borrowings to decrease, and the value of our debt acquisitions to increase.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act) that are designed to ensure that the information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and such information is accumulated and communicated to management, including the Chief Executive Officer (principal executive officer) and the Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurances of achieving the desired control objectives.

We carried out an evaluation, under the supervision and with the participation of our management, including the Chief Executive Officer and the Principal Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of ~~June~~September 30, 2025. Based upon ~~that~~ that evaluation, our Chief Executive Officer and Principal Financial Officer have concluded that, as of ~~June~~September 30, 2025, our disclosure ~~controls~~ controls and procedures were effective to accomplish their objectives at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

No changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act) occurred during the quarter ended ~~June~~September 30, 2025, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
