New Mountain Guardian IV Income Fund, L.L.C.

(in thousands, except unit data)

(unaudited)

Note 1. Formation and Business Purpose

New Mountain Guardian IV Income Fund, L.L.C. (the "Company"), formerly known as New Mountain Guardian IV Unlevered BDC, L.L.C., is a Delaware limited liability company formed on November 4, 2022. The Company is a closed-end, non-diversified management investment company that has elected to be regulated as a business development company ("BDC") under the Investment Company Act of 1940, as amended (the "1940 Act"). The Company has elected to be treated for U.S. federal income tax purposes, and intends to comply with the requirements to continue to qualify annually, as a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code").

New Mountain Finance Advisers, L.L.C. (the "Investment Adviser"), formerly known as New Mountain Finance Advisers BDC, L.L.C., is a wholly-owned subsidiary of New Mountain Capital Group, L.P. (together with New Mountain Capital, L.L.C. and its affiliates, "New Mountain Capital"), whose ultimate owners include Steven B. Klinsky, other current and former New Mountain Capital professionals and related vehicles and a minority investor. New Mountain Capital is a global investment firm with over $55.0 billion of assets under management and a track record of investing in the middle market. New Mountain Capital focuses on investing in defensive growth companies across its private equity, credit and net lease investment strategies. The Investment Adviser manages the Company's day-to-day operations and provides it with investment advisory and management services. The Investment Adviser also manages other funds that may have investment mandates that are similar, in whole or in part, to the Company's. New Mountain Finance Administration, L.L.C. (the "Administrator"), a wholly-owned subsidiary of New Mountain Capital, provides the administrative services necessary to conduct the Company's day-to-day operations. The Administrator has hired a third-party sub-administrator to assist with the provision of administrative services.

The Company conducted a private offering (the "Private Offering") of units of the Company's limited liability company interests (the "Units") to investors in reliance on exemptions from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). Units were offered for subscription continuously throughout the Closing Period (as defined below). Each investor in the Private Offering made a capital commitment (each, a "Capital Commitment") to purchase Units pursuant to a subscription agreement entered into with the Company (each, a "Subscription Agreement"). Closings of the Private Offering occurred, from time to time, in the Investment Adviser's sole discretion, during the 18-month period (the "Closing Period") following the initial closing of Capital Commitments, which occurred on May 23, 2023. On November 20, 2024, pursuant to the limited liability company agreement as amended and restated on July 10, 2023 (the "A&R LLC Agreement" ), the Investment Adviser elected to extend the Closing Period from November 23, 2024 to March 31, 2025. At the end of the Closing Period, the Company had aggregate Capital Commitments from investors of $512,405. The Company accepted and drew down on Capital Commitments from investors throughout the Closing Period and may draw down on Capital Commitments after the Closing Period. The Company commenced loan origination and investment activities on May 24, 2023. The "Investment Period" began on May 23, 2023 and will continue until March 31, 2029, the four-year anniversary of the end of the Closing Period. The term of the Company is until March 31, 2031, six years from the end of the Closing Period, subject to (i) a one-year extension as determined by the Investment Adviser in its sole discretion and (ii) an additional one year extension as determined by the Company's board of directors (the "Board").

The Company focuses on providing direct lending solutions to U.S. upper middle market companies backed by top private equity sponsors. The Company's investment objective is to generate current income and capital appreciation through the sourcing and origination of senior secured loans and select junior capital positions, to growing businesses in defensive industries that offer attractive risk-adjusted returns. The Company's differentiated investment approach leverages the deep sector knowledge and operating resources of New Mountain Capital.

The Company primarily invests in senior secured debt of U.S. sponsor-backed, middle market companies. The Company defines middle market companies as those with annual earnings before interest, taxes, depreciation and amortization ("EBITDA") between $10,000 and $200,000. The Company focuses on defensive growth businesses that generally exhibit the following characteristics: (i) acyclicality, (ii) sustainable secular growth drivers, (iii) niche market dominance and high barriers to competitive entry, (iv) recurring revenue and strong free cash flow, (v) flexible cost structures and (vi) seasoned management teams.

Senior secured loans may include traditional first lien loans or unitranche loans. The Company invests a significant portion of its portfolio in unitranche loans, which are loans that combine both senior and subordinated debt, generally in a first-lien position. Because unitranche loans combine characteristics of senior and subordinated debt, they have risks similar to the risks associated with secured debt and subordinated debt. Certain unitranche loan investments may include “last-out” positions, which generally heighten the risk of loss. In some cases, the Company’s investments may also include equity interests.

As of June 30, 2025, the Company's top five industry concentrations were software, business services, healthcare, financial services and education.

Note 2. Summary of Significant Accounting Policies

Basis of accounting—The Company's financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP"). The Company is an investment company following accounting and reporting guidance in Accounting Standards Codification Topic 946, Financial Services—Investment Companies ("ASC 946").

The Company's financial statements reflect all adjustments and reclassifications which, in the opinion of management, are necessary for the fair presentation of the results of operations and financial condition for the period(s) presented. Revenues are recognized when earned and expenses when incurred. The financial results of the Company's portfolio investments are not consolidated in the financial statements.

The Company's interim financial statements are prepared in accordance with GAAP and pursuant to the requirements for reporting on Form 10-Q and Articles 6 and 10 of Regulation S-X. Accordingly, the Company’s interim financial statements do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, all adjustments, consisting solely of normal recurring accruals considered necessary for the fair presentation of financial statements for the interim period, have been included. The current period's results of operations will not necessarily be indicative of results that ultimately may be achieved for the fiscal year ending December 31, 2025.

Investments—The Company applies fair value accounting in accordance with GAAP. Fair value is the amount 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. Investments are reflected on the Company's Statements of Assets, Liabilities and Members' Capital at fair value, with changes in unrealized gains and losses resulting from changes in fair value reflected on the Company's Statements of Operations as "Net change in unrealized appreciation (depreciation) of investments" and realizations on portfolio investments reflected on the Company's Statements of Operations as "Net realized gains (losses) on investments".

The Company values its assets on a quarterly basis, or more frequently if required under the 1940 Act. In all cases, the Board is ultimately and solely responsible for determining the fair value of the Company's portfolio investments on a quarterly basis in good faith, including investments that are not publicly traded, those whose market prices are not readily available and any other situation where its portfolio investments require a fair value determination. Security transactions are accounted for on a trade date basis. The Company's quarterly valuation procedures are set forth in more detail below:

(1)Investments for which market quotations are readily available on an exchange are valued at such market quotations based on the closing price indicated from independent pricing services.

(2)Investments for which indicative prices are obtained from various pricing services and/or brokers or dealers are valued through a multi-step valuation process, as described below, to determine whether the quote(s) obtained is representative of fair value in accordance with GAAP.

a.Bond quotes are obtained through independent pricing services. Internal reviews are performed by the investment professionals of the Investment Adviser to ensure that the quote obtained is representative of fair value in accordance with GAAP and, if so, the quote is used. If the Investment Adviser is unable to sufficiently validate the quote(s) internally and if the investment's par value or its fair value exceeds the materiality threshold, the investment is valued similarly to those assets with no readily available quotes (see (3) below); and

b.For investments other than bonds, the Company looks at the number of quotes readily available and performs the following procedures:

i.Investments for which two or more quotes are received from a pricing service are valued using the mean of the mean of the bid and ask of the quotes obtained. The Company will evaluate the reasonableness of the quote, and if the quote is determined to not be representative of fair value, the Company will use one or more of the methodologies outlined below to determine fair value; and

ii.Investments for which one quote is received from a pricing service are validated internally. The investment professionals of the Investment Adviser analyze the market quote obtained using an array of valuation methods (further described below) to validate the fair value. If the Investment Adviser is unable to sufficiently validate the quote internally and if the investment's par value or its fair value exceeds the materiality threshold, the investment is valued similarly to those assets with no readily available quotes (see (3) below).

(3)Investments for which quotations are not readily available through exchanges, pricing services, brokers or dealers are valued through a multi-step valuation process:

41

a.Each portfolio company or investment is initially valued by the investment professionals of the Investment Adviser responsible for the credit monitoring;

b.Preliminary valuation conclusions will then be documented and discussed with the Company's senior management;

c.If an investment falls into (3) above for four consecutive quarters and if the investment's par value or its fair value exceeds the materiality threshold, then at least once each fiscal year, the valuation for each portfolio investment for which the Company does not have a readily available market quotation will be reviewed by an independent valuation firm engaged by the Board; and

d.When deemed appropriate by the Company's management, an independent valuation firm may be engaged to review and value investment(s) of a portfolio company, without any preliminary valuation being performed by the Investment Adviser. The investment professionals of the Investment Adviser will review and validate the value provided.

For investments in revolving credit facilities and delayed draw commitments, the cost basis of the funded investments purchased is offset by any costs/netbacks received for any unfunded portion on the total balance committed. The fair value is also adjusted for the price appreciation or depreciation on the unfunded portion. As a result, the purchase of a commitment not completely funded may result in a negative fair value until it is called and funded.

The values assigned to investments are based upon available information and do not necessarily represent amounts which might ultimately be realized, since such amounts depend on future circumstances and cannot be reasonably determined until the individual positions are liquidated. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Company's investments may fluctuate from period to period and the fluctuations could be material.

See Note 3. Investments, for further discussion relating to investments.

Cash and cash equivalents—Cash and cash equivalents include cash and short-term, highly liquid investments. The Company defines cash equivalents as securities that are readily convertible into known amounts of cash and so near maturity that there is insignificant risk of changes in value. These securities have original maturities of three months or less. The Company did not hold any cash equivalents as of June 30, 2025 and December 31, 2024. The cash deposits are FDIC insured up to $250 per ownership category, per institution.

Revenue recognition

Sales and paydowns of investments: Realized gains and losses on investments are determined on the specific identification method.

Interest and dividend income: Interest income, including amortization of premium and discount using the effective interest method, is recorded on the accrual basis and periodically assessed for collectability. Interest income also includes interest earned from cash on hand. Upon the prepayment of a loan or debt security, any prepayment penalties are recorded as part of interest income. The Company has loans and certain preferred equity investments in its portfolio that contain a payment-in-kind ("PIK") interest or dividend provision. PIK interest and dividends are accrued and recorded as income at the contractual rates, if deemed collectible. The PIK interest and dividends are added to the principal or share balances on the capitalization dates and are generally due at maturity or when redeemed by the issuer. For the three and six months ended June 30, 2025 the Company recognized PIK interest from investments of $190 and $388, respectively, and PIK dividends from investments of $26 and $52, respectively. For the three and six months ended June 30, 2024 the Company recognized PIK interest from investments of $252 and $396, respectively, and no PIK dividends from investments.

Dividend income on preferred securities is recorded as dividend income on an accrual basis to the extent that such amounts are deemed collectible.

Non-accrual income: Investments are placed on non-accrual status when principal or interest payments are past due for 30 days or more and when there is reasonable doubt that principal or interest will be collected. Accrued cash and un-capitalized PIK interest or dividends are reversed when an investment is placed on non-accrual status. Previously capitalized PIK interest or dividends are not reversed when an investment is placed on non-accrual status. Interest or dividend payments received on non-accrual investments may be recognized as income or applied to principal depending upon management's judgment of the ultimate collectability. Non-accrual investments are restored to accrual status when past due principal and interest is paid and, in management's judgment, are likely to remain current. As of June 30, 2025 and December 31, 2024, no investments were on non-accrual status.

Fee income: Fee income represents delayed compensation, revolver fees, upfront fees, amendment fees and other miscellaneous fees received and are typically non-recurring in nature. Delayed compensation is income earned from

42

counterparties on trades that do not settle within a set number of business days after the trade date. Fee income may also include fees from bridge loans. The Company may from time to time enter into bridge financing commitments, an obligation to provide interim financing to a counterparty until permanent credit can be obtained. These commitments are short-term in nature and may expire unfunded. A fee is received by the Company for providing such commitments. Structuring fees and upfront fees are recognized as income when earned, usually when paid at the closing of the investment, and are non-refundable.

Interest and other financing expenses—Interest and other financing fees are recorded on an accrual basis by the Company. See Note 6. Borrowings, for details.

Organizational expenses—Organizational expenses include costs and expenses incurred in connection with the formation and organization of the Company and are expensed as incurred on the Statements of Operations. Any organizational and offering expenses paid by the Company in excess of the lesser of $2,000 or 0.25% of the aggregate Capital Commitments pursuant to the Expense Limitation and Reimbursement Agreement (as defined below), will be applied as a reduction to the base management fee paid to the Investment Adviser and cannot be recouped by the Investment Adviser.

Deferred offering costs—The Company's deferred offering costs consist of fees and expenses incurred in connection with the offering of the Company's Units. Upon the issuance of Units, deferred offering costs are then amortized into Organizational and Offering Expenses on the Statements of Operations on a straight line basis over a period of 12 months beginning on the date of commencement of operations. Deferred offering costs are included on the Company’s Statements of Assets, Liabilities and Members' Capital until amortized.

Deferred financing costs—The deferred financing costs of the Company consist of capitalized expenses related to the origination and amending of the Company's borrowings. The Company amortizes these costs into expense over the stated life of the related borrowing. See Note 6. Borrowings, for details.

Income taxes— The Company has elected to be treated as a RIC for U.S. federal income tax purposes under Subchapter M of the Code and intends to comply with the requirements to qualify and maintain its status as a RIC annually. As a RIC, the Company is not subject to U.S. federal income tax on the portion of taxable income and gains timely distributed to its unitholders.

To continue to qualify and be subject to tax treatment as a RIC, the Company is required to meet certain income and asset diversification tests in addition to timely distributing at least 90.0% of its investment company taxable income, as defined by the Code. Since U.S. federal income tax regulations differ from GAAP, distributions in accordance with tax regulations may differ from net investment income and realized gains recognized for financial reporting purposes.

Differences between taxable income and the results of operations for financial reporting purposes may be permanent or temporary in nature. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Differences in classification may also result from the treatment of short-term gains as ordinary income for U.S. federal income tax purposes.

For U.S. federal income tax purposes, distributions paid to unitholders of the Company are reported as ordinary income, return of capital, long term capital gains or a combination thereof.

The Company will be subject to a 4.0% nondeductible federal excise tax on certain undistributed income unless the Company distributes, in a timely manner as required by the Code, an amount at least equal to the sum of (1) 98.0% of its respective net ordinary income earned for the calendar year and (2) 98.2% of its respective capital gain net income for the one-year period ending October 31 in the calendar year.

Based on its analysis, the Company has determined that there were no uncertain tax positions that do not meet the more likely than not threshold as defined by Accounting Standards Codification Topic 740, Income Taxes ("ASC 740") through December 31, 2024. The 2023 and 2024 tax years and forward remain subject to examination by the U.S. federal, state, and local tax authorities.

Distributions—Distributions to the Company's unitholders are recorded on the record date as set by the Board. The Company intends to make timely distributions to its unitholders that will be sufficient to enable the Company to qualify and maintain its status as a RIC. The Company intends to distribute approximately all of its net investment income on a quarterly basis and substantially all of its taxable income on an annual basis, except that the Company may retain certain net capital gains for reinvestment.    

Earnings per Unit—The Company's earnings per Unit ("EPU") amounts have been computed based on the weighted-average number of Units outstanding for the period. Basic EPU is computed by dividing net increase (decrease) in members' capital resulting from operations by the weighted average number of Units outstanding during the period of computation. Diluted EPU is computed by dividing net increase (decrease) in members' capital resulting from operations by the weighted average number of Units assuming all potential Units had been issued, and its related net impact to members' capital accounted

43

for, and the additional Units were dilutive. Diluted EPU reflects the potential dilution, using the as-if-converted method for convertible debt, which could occur if all potentially dilutive securities were exercised.

Foreign securities—The accounting records of the Company are maintained in U.S. dollars. Investment securities denominated in foreign currencies are translated into U.S. dollars based on the rate of exchange of such currencies on the date of valuation. Purchases and sales of investment securities and income and expense items denominated in foreign currencies are translated into U.S. dollars based on the rate of exchange of such currencies on the respective dates of the transactions. The Company isolates that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with "Net change in unrealized appreciation (depreciation) of investments" and "Net realized gains (losses) on investments" on the Company's Statements of Operations.

Investments denominated in foreign currencies may be negatively affected by movements in the rate of exchange between the U.S. dollar and foreign currencies. This movement is beyond the control of the Company and cannot be predicted.

Use of estimates—The preparation of the Company's financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the Company's financial statements and the reported amounts of revenues and expenses during the reporting periods. Changes in the economic environment, financial markets and other metrics used in determining these estimates could cause actual results to differ from the estimates used, and the differences could be material.

For discussion of the Company's unfunded commitments, see Note 8. Commitments and Contingencies.

Investment Risk Factors—First and second lien debt that the Company invests in is almost entirely rated below investment grade or may be unrated. Debt investments rated below investment grade are often referred to as "leveraged loans", "high yield" or "junk" debt investments, and may be considered "high risk" compared to debt investments that are rated investment grade. These debt investments are considered speculative because of the credit risk of the issuers. Such issuers are considered more likely than investment grade issuers to default on their payments of interest and principal, and such risk of default could reduce the members' capital and income distributions of the Company. In addition, some of the Company's debt investments will not fully amortize during their lifetime, which could result in a loss or a substantial amount of unpaid principal and interest due upon maturity. First and second lien debt may also lose significant market value before a default occurs. Furthermore, an active trading market may not exist for these first and second lien debt investments. This illiquidity may make it more difficult to value the debt investments.

Subordinated debt is generally subject to similar risks as those associated with first and second lien debt, except that such debt is subordinated in payment and/or lower in lien priority. Subordinated debt is subject to the additional risk that the cash flow of the borrower and the property securing the debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured and unsecured obligations of the borrower.

The Company may directly invest in the equity of private companies or, in some cases, equity investments could be made in connection with a debt investment. Equity investments may or may not fluctuate in value, resulting in recognized realized gains or losses upon disposition.

Note 4. Fair Value

Pursuant to Rule 2a-5 under the 1940 Act, a market quotation is readily available for purposes of Section 2(a)(41) of the 1940 Act with respect to a security only when that “quotation is a quoted price (unadjusted) in active markets for identical investments that the fund can access at the measurement date, provided that a quotation will not be readily available if it is not reliable”. Fair value is the amount 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. Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosure ("ASC 820") establishes a fair value hierarchy that prioritizes and ranks the inputs to valuation techniques used in measuring investments at fair value. The hierarchy classifies the inputs used in measuring fair value into three levels as follows:    

Level I—Quoted prices (unadjusted) are available in active markets for identical investments and the Company has the ability to access such quotes as of the reporting date. The type of investments which would generally be included in Level I include active exchange-traded equity securities and exchange-traded derivatives. As required by ASC 820, the Company, to the extent that it holds such investments, does not adjust the quoted price for these investments, even in situations where the Company holds a large position and a sale could reasonably impact the quoted price.

Level II—Pricing inputs are observable for the investments, either directly or indirectly, as of the reporting date, but are not the same as those used in Level I. Level II inputs include the following:

•Quoted prices for similar assets or liabilities in active markets;

•Quoted prices for identical or similar assets or liabilities in non-active markets (examples include corporate and municipal bonds, which trade infrequently);

•Pricing models whose inputs are observable for substantially the full term of the asset or liability (examples include most over-the-counter derivatives, including foreign exchange forward contracts); and

•Pricing models whose inputs are derived principally from or corroborated by observable market data through correlation or other means for substantially the full term of the asset or liability.

Level III—Pricing inputs are unobservable for the investment and include situations where there is little, if any, market activity for the investment.

The inputs used to measure fair value may fall into different levels. In all instances when the inputs fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level of input that is significant to the fair value measurement in its entirety. As such, a Level III fair value measurement may include inputs that are both observable and unobservable. Gains and losses for such assets categorized within the Level III table below may include changes in fair value that are attributable to both observable inputs and unobservable inputs.

The inputs into the determination of fair value require significant judgment or estimation by management and consideration of factors specific to each investment. A review of the fair value hierarchy classifications is conducted on a quarterly basis. Changes in the observability of valuation inputs may result in the transfer of certain investments within the fair value hierarchy from period to period.

The following table summarizes the levels in the fair value hierarchy that the Company's portfolio investments fell into as of June 30, 2025:

(1)As of June 30, 2024, portfolio investments were transferred into Level III from Level II and out of Level III into Level II at fair value as of the beginning of the period in which the reclassification occurred.

Except as noted in the tables above, there were no other transfers in or out of Levels I, II, or III during the three and six months ended June 30, 2025 and June 30, 2024. Transfers into Level III occur as quotations obtained through pricing services are deemed not representative of fair value as of the balance sheet date, and such assets are internally valued. As quotations obtained through pricing services are substantiated through additional market sources, investments are transferred out of Level III. In addition, transfers out of Level III and transfers into Level III occur based on the increase or decrease in the availability of certain observable inputs. Investments will be transferred into Level III from Level II and out of Level III into Level II at fair value as of the beginning of the period in which the reclassification occurred.

The Company invests in revolving credit facilities. These investments are categorized as Level III investments as these assets are not actively traded and their fair values are often implied by the term loans of the respective portfolio companies.

The Company generally uses the following framework when determining the fair value of investments where there is little, if any, market activity or observable pricing inputs. The Company typically determines the fair value of its performing debt investments utilizing an income approach. Additional consideration is given using a market based approach, as well as reviewing the overall underlying portfolio company's performance and associated financial risks. The following outlines additional details on the approaches considered:

Company Performance, Financial Review, and Analysis:    Prior to investment, as part of its due diligence process, the Company evaluates the overall performance and financial stability of the portfolio company. Post investment, the Company analyzes each portfolio company's current operating performance and relevant financial trends versus prior year and budgeted results, including, but not limited to, factors affecting its revenue and EBITDA growth, margin trends, liquidity position, covenant compliance and changes to its capital structure. The Company also attempts to identify and subsequently track any developments at the portfolio company within its customer or vendor base, or within the industry or the macroeconomic environment, generally, that may alter any material element of its original investment thesis. This analysis is specific to each portfolio company. The Company leverages the knowledge gained from its original due diligence process, augmented by this subsequent monitoring, to continually refine its outlook for each of its portfolio companies and ultimately form the valuation of its investment in each portfolio company. When an external event such as a purchase transaction, public offering or subsequent sale occurs, the Company will consider the pricing indicated by the external event to corroborate the private valuation.

For debt investments, the Company may employ the Market Based Approach (as described below) to assess the total enterprise value of the portfolio company, in order to evaluate the enterprise value coverage of the Company's debt investment. For equity investments or in cases where the Market Based Approach implies a lack of enterprise value coverage for the debt investment, the Company may additionally employ a discounted cash flow analysis based on the free cash flows of the portfolio company to assess the total enterprise value. After enterprise value coverage is demonstrated for the Company's debt investments through the method(s) above, the Income Based Approach (as described below) may be employed to estimate the fair value of the investment.

49

Market Based Approach:    The Company may estimate the total enterprise value of each portfolio company by utilizing EBITDA or revenue multiples of publicly traded comparable companies and comparable transactions. The Company considers numerous factors when selecting the appropriate companies whose trading multiples are used to value its portfolio companies. These factors include, but are not limited to, the type of organization, similarity to the business being valued, and relevant risk factors, as well as size, profitability and growth expectations. The Company may apply an average of various relevant comparable company EBITDA or revenue multiples to the portfolio company's latest twelve month ("LTM") EBITDA or revenue or projected EBITDA or revenue to calculate the enterprise value of the portfolio company. Significant increases or decreases in the EBITDA or revenue multiples will result in an increase or decrease in enterprise value, which may result in an increase or decrease in the fair value estimate of the investment. In applying the Market Based Approach as of June 30, 2025 and December 31, 2024, the Company used the relevant EBITDA or revenue multiple ranges set forth in the table below to determine the enterprise value of its portfolio companies. The Company believes these were reasonable ranges in light of current comparable company trading levels and the specific portfolio companies involved.

Income Based Approach:    The Company also may use a discounted cash flow analysis to estimate the fair value of the investment. Projected cash flows represent the relevant security's contractual interest, fee and principal payments plus the assumption of full principal recovery at the investment's expected maturity date. These cash flows are discounted at a rate established utilizing a combination of a yield calibration approach and a comparable investment approach. The yield calibration approach incorporates changes in the credit quality (as measured by relevant statistics) of the portfolio company, as compared to changes in the yield associated with comparable credit quality market indices, between the date of origination and the valuation date. The comparable investment approach utilizes an average yield-to-maturity of a selected set of high-quality, liquid investments to determine a comparable investment discount rate. Significant increases or decreases in the discount rate would result in a decrease or increase in the fair value measurement. In applying the Income Based Approach as of June 30, 2025 and December 31, 2024, the Company used the discount ranges set forth in the table below to value investments in its portfolio companies.

The unobservable inputs used in the fair value measurement of the Company's Level III investments as of June 30, 2025 were as follows:

					Range

The BMO Subscription Line (as defined below) and the Unsecured Management Company Revolver (as defined below) are considered Level III investments. See Note 6. Borrowings for details.

The following are the principal amounts and fair values of the Company's borrowings as of June 30, 2025 and December 31, 2024. As of June 30, 2025 and December 31, 2024, there was no balance outstanding under the Unsecured Management Company Revolver. Fair value is estimated by discounting remaining payments using applicable current market rates, which take into account changes in the Company's marketplace credit ratings, or market quotes, if available.

Fair value risk factors—The Company seeks investment opportunities that offer the possibility of attaining substantial capital appreciation. Certain events particular to each industry in which the Company's portfolio companies conduct their operations, as well as general economic, political and health conditions, may have a significant negative impact on the operations and profitability of the Company's investments and/or on the fair value of the Company's investments. The Company's investments are subject to the risk of non-payment of scheduled interest or principal, resulting in a reduction in income to the Company and their corresponding fair valuations. Also, there may be risk associated with the concentration of investments in one geographic region or in certain industries. These events are beyond the control of the Company and cannot be predicted. Furthermore, the ability to liquidate investments and realize value is subject to uncertainties.

Note 5. Agreements and Related Parties

The Company entered into an investment advisory and management agreement (the "Investment Management Agreement") with the Investment Adviser on December 14, 2022. The Investment Management Agreement initially had a term of two years which began on December 14, 2022, and thereafter will continue automatically for successive annual periods, provided that such continuance is specifically approved at least annually by (A) the vote of the Board, or by the vote of a majority of the outstanding voting securities of the Company and (B) the vote of a majority of the Company's directors who are not parties to the Investment Management Agreement or "interested persons" (as such term is defined in Section 2(a)(19) of the 1940 Act) of any such party, in accordance with the requirements of the 1940 Act. The Investment Management Agreement was most recently re-approved by the Board on January 29, 2025, at an in person meeting, for a period of 12 months commencing on March 1, 2025. Under the Investment Management Agreement, the Investment Adviser manages the day-to-day operations of, and provides investment advisory services to, the Company. For providing these services, the Investment Adviser receives an annual base management fee and incentive fee from the Company.

Pursuant to the Investment Management Agreement, the base management fee is payable quarterly in arrears at an annual rate of 0.75% of the aggregate contributed capital from all unitholders (including any outstanding borrowings under any subscription line drawn in lieu of capital calls) less any return of capital distributions and less any cumulative realized losses since inception (calculated net of any subsequently reversed realized losses and net of any realized gains) as of the last day of the applicable quarter. For the period from the effective date of the Investment Management Agreement through the one year anniversary of the Initial Drawdown Date (as defined in the Investment Management Agreement), the base management fee was reduced by 50% (for the avoidance of doubt, this resulted in an annual management fee rate of 0.375% through May 31, 2024. Because the one year anniversary of the Initial Drawdown Date occurred on a date other than the last day of a calendar quarter, the management fee was prorated for such calendar quarter and calculated based on the number of days in such period up to, and including, the one year anniversary of the Initial Drawdown Date. The base management fee could also be reduced by any voluntary fee waivers made by the Investment Adviser. The management fee will be reduced, but not below zero, by any amounts paid by the Company or its subsidiaries to a placement agent, any organizational and offering expenses in excess of the lesser of $2,000 or 0.25% of the aggregate Capital Commitments pursuant to the Expense Limitation and Reimbursement Agreement (as defined below), and any fund expenses in excess of the Specified Expenses Cap (as defined below).

The Investment Adviser has entered into agreements with placement agents that provide for ongoing payments from the Investment Adviser based upon the amount of a unitholder's Capital Commitment or capital contributions. Neither the Company nor any unitholders will bear any of the fees paid to placement agents of the Company as any such fees paid by the Company will offset the management fees.

The incentive fee consists of two components that are independent of each other, with the result that one component may be payable even if the other is not. A portion of the incentive fee is based on a percentage of the Company's income and a portion is based on a percentage of the Company's capital gains, each as described below.

Incentive Fee on Pre-Incentive Fee Net Investment Income

The portion based on the Company's income (the "Income Incentive Fee") is based on pre-incentive fee net investment income ("Pre-Incentive Fee Net Investment Income"). Pre-Incentive Fee Net Investment Income means interest income, dividend income and any fee income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, upfront, diligence and consulting fees or other fees that the Company receives from portfolio companies) accrued during the calendar quarter, minus the Company's operating expenses for the quarter (including the base management fee, expenses payable under the Administration Agreement, and any interest expense and distributions paid on any issued and outstanding preferred units, but excluding the incentive fee). Pre-Incentive Fee Net Investment Income includes, in the case of investments with a deferred interest feature (such as original issue discount, debt instruments with PIK interest and zero coupon securities), accrued income that we have not yet received in cash. Pre-Incentive Fee Net Investment Income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation.

Pre-Incentive Fee Net Investment Income, expressed as a rate of return on the value of the Company's members' capital at the end of the immediately preceding quarter, is compared to a "hurdle rate" of return of 1.25% per quarter (5.0% annualized).

The Company will pay the Investment Adviser an incentive fee quarterly in arrears with respect to the Company's Pre-Incentive Fee Net Investment Income in each calendar quarter as follows:

•no incentive fee based on Pre-Incentive Fee Net Investment Income in any calendar quarter in which the Company's Pre-Incentive Fee Net Investment Income does not exceed the hurdle rate of 1.25% (5.0% annualized);

•100% of the dollar amount of our Pre-Incentive Fee Net Investment Income with respect to that portion of such Pre-Incentive Fee Net Investment Income, if any, that exceeds the hurdle rate but is less than or equal to a rate of return of 1.389% (5.556% annualized). The Company refers to this portion of the Company's Pre-Incentive Fee Net Investment Income (which exceeds the hurdle rate but is less than 1.389%) as the "catch-up." The "catch-up" is meant to provide the Investment Adviser with approximately 10.0% of the Company's Pre-Incentive Fee Net Investment Income as if a hurdle rate did not apply if this net investment income exceeds 1.389% in any calendar quarter; and

•10.0% of the dollar amount of the Company's Pre-Incentive Fee Net Investment Income, if any, that exceeds a rate of return of 1.389% (5.556% annualized). This reflects that once the hurdle rate is reached and the catch-up is achieved, 10.0% of all Pre-Incentive Fee Net Investment Income thereafter is allocated to the Investment Adviser.

For both the three and six months ended June 30, 2025 and June 30, 2024, incentive fees waived were under $1 thousand. The fees that are payable under the Investment Management Agreement for any partial period will be appropriately prorated.

52

Incentive Fee on Capital Gains

The second component of the incentive fee is the capital gains incentive fee. The Company will pay the Investment Adviser an incentive fee with respect to the Company's cumulative realized capital gains computed net of all realized capital losses and unrealized capital depreciation since inception ("Cumulative Net Realized Gains") based on the waterfall below:

a.First, no incentive fee is payable to the Investment Adviser on Cumulative Net Realized Gains until total return of capital distributions, distributions of net investment income and distributions of net realized capital gains to unitholders is equal to total capital contributions;

b.Second, no incentive fee is payable to the Investment Adviser on Cumulative Net Realized Gains until the Company has paid cumulative distributions equal to an annualized, cumulative internal rate of return of 5.0% on the total contributed capital to the Company calculated from the date that each such amount was due to be contributed to the Company until the date each such distribution is paid;

c.Third, upon a distribution that results in cumulative distributions exceeding the amounts in clause (a) and (b) above, an incentive fee on capital gains payable to the Investment Adviser equal to 100.0% of the amount of Cumulative Net Realized Gains until the Investment Adviser has received (together with amounts the Investment Adviser has received under Income Incentive Fees) an amount equal to 10.0% of the sum of (i) the cumulative distributions to unitholders made pursuant to clause (b) above, (ii) Income Incentive Fee paid to the Investment Adviser and (iii) amounts paid to the Investment Adviser pursuant to this clause (c); and

d.Thereafter, an incentive fee on capital gains equal to 10.0% of additional undistributed Cumulative Net Realized Gains.

Upon termination of the Company, the Investment Adviser will be required to return incentive fees to the Company to the extent that: (i) the Investment Adviser has received cumulative incentive fees in excess of 10.0% of the sum of (A) the Company's cumulative distributions other than return of capital contributions and (B) the cumulative incentive fees paid to the Investment Adviser; or (ii) the unitholders have not received a 5.0% cumulative internal rate of return; provided that in no event will such restoration be more than the incentive fees received by the Investment Adviser.

In accordance with GAAP, the Company accrues a hypothetical capital gains incentive fee based upon the cumulative net realized capital gains and realized capital losses and the cumulative net unrealized capital appreciation and unrealized capital depreciation on investments held at the end of each period. The accrual for any capital gains incentive fee under GAAP in a given period may result in an additional expense if such cumulative amount is greater than such cumulative amount in the prior period or a reduction of previously recorded expense if such cumulative amount is less than the amount in the prior period. If such cumulative amount is negative, then there is no accrual. Actual amounts paid to the Investment Adviser are consistent with the Investment Management Agreement and are based only on realized capital gains computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis from inception through the end of each calendar year.

Incentive Fee Waiver

On December 18, 2023, the Company and the Investment Adviser entered into a voluntary letter waiver agreement (the “Waiver Agreement”) effective as of January 1, 2024, whereby the Investment Adviser agreed to waive certain portions of the incentive fees paid by the Company to the Investment Adviser pursuant to the Investment Management Agreement. The Waiver Agreement increases the hurdle rate, as described above, to 6.0% and waives any income based incentive fees that would have been earned at the current hurdle rate of 5.0%, so long as the average three-month SOFR over the trailing three-month period (the “Three Month SOFR”) is equal to or greater than 3.0% on the last day of the applicable quarter. If the Three Month SOFR falls below 3.0% on the last day of the applicable quarter, the hurdle rate will reset to 5.0%. Additionally, through the Waiver Agreement and with respect to the incentive fee on capital gains, the annualized, cumulative internal rate of return will be calculated using a Weighted Average Hurdle Rate (as defined in the Waiver Agreement) that takes into account any hurdle rate increases during the year.

Expense Limitation

Notwithstanding the foregoing, the Investment Adviser has agreed to reduce and/or waive its management fee (the "Specified Expenses Cap") each year such that the Company will not be required to pay Specified Expenses (as defined below) in excess of a maximum aggregate amount in any calendar year (prorated for partial years and portions of years for which each applicable prong of the cap applies) equal to: (1) during the Closing Period, 0.40% of the greater of (A) $500,000 or (B) actual aggregate Capital Commitments as of the end of such calendar year, (2) at the end of the Closing Period until the end of the Investment Period, 0.40% of aggregate Capital Commitments and (3) after the end of the Investment Period, 0.40% of the Company's average Members' Capital for the calendar year. Further, if the actual aggregate committed capital of the Company at the end of the Closing Period is less than $500,000, the prong of the Specified Expenses Cap in clause (1) above will be retroactively adjusted to equal 0.40% of aggregate Capital Commitments at the end of the Closing Period, and the Investment

53

Adviser has agreed to further reduce and/or waive its management fee for the year in which the Closing Period ends in an amount equal to the difference between (A) the amount that would have been required to be waived/reimbursed pursuant to clause (1) above as adjusted and (B) the amount previously waived/reimbursed pursuant to clause (1) above. "Specified Expenses" of the Company means all Company Expenses (as defined under "Fund Expenses" in the "A&R LLC Agreement") incurred in the operation of the Company with the exception of: (i) the management fee, (ii) any incentive fees, (iii) Organizational and Offering Expenses (as defined in the A&R LLC Agreement) (which are subject to the Organizational and Offering Expenses Cap as defined in the A&R LLC Agreement), (iv) Placement Fees (as defined in the A&R LLC Agreement), (v) interest on and fees and expenses arising out of all Company indebtedness and other financing, (vi) costs of any litigation and damages (including the costs of any indemnity or contribution right granted to any placement agent or third-party finder engaged by the Company or its affiliates) and (vii) for the avoidance of doubt, if applicable, any investor level withholding or other taxes.

If, while the Investment Adviser is the investment adviser to the Company, the annualized Specified Expenses for a given calendar year are less than the Specified Expenses Cap, the Investment Adviser shall be entitled to reimbursement by the Company of the compensation waived and other expenses borne by the Investment Adviser (the "Reimbursement Amount") on behalf of the Company pursuant to the expense limitation and reimbursement agreement between the Company and the Investment Adviser (the "Expense Limitation and Reimbursement Agreement") during any of the previous thirty-six months, and provided that such amount paid to the Investment Adviser will in no event exceed the total Reimbursement Amount and will not include any amounts previously reimbursed. The Reimbursement Amount plus the annualized Specified Expenses for a given calendar year shall not exceed the Specified Expenses Cap. The Investment Adviser may recapture a Specified Expense in any year within the thirty-six month period after the Investment Adviser bears the expense. For both the three and six months ended June 30, 2025 and June 30, 2024, there were no reimbursements paid by the Company to the Investment Adviser pursuant to this provision.

The Expense Limitation and Reimbursement Agreement may be amended by mutual agreement of the parties, provided that any amendment that could result in an increase in expenses borne by the Company also must be approved by vote of a majority of the Company's outstanding Units.

The following table summarizes the management fees and incentive fees incurred by the Company for the three and six months ended June 30, 2025 and June 30, 2024:

	Three Months Ended				Six Months Ended
	June 30, 2025		June 30, 2024		June 30, 2025		June 30, 2024
Management fee	$	755	$	460	$	1,481	$	676
Less: management fee waiver	(5)		(164)		(5)		(272)
Net management fee	750		296		1,476		404
Income based incentive fee	$	843	$	434	$	1,635	$	725
Capital gains incentive fee	$	(30)	$	—	$	(142)	$	—

As of June 30, 2025 and December 31, 2024, $0 and $142, respectively, of incentive fees on capital gains were accrued but are not payable under the Investment Management Agreement by the Company, as return of capital distributions, distributions of net investment income and distributions of net realized capital gains to unitholders did not exceed capital contributions.

The Company has entered into an administration agreement with the Administrator (the "Administration Agreement") under which the Administrator provides administrative services to the Company for its day-to-day operations. The Administration Agreement was most recently re-approved by the Board on January 29, 2025 for a period of 12 months commencing on March 1, 2025. The Administrator maintains, or oversees the maintenance of, the Company's financial records, prepares reports filed with the U.S. Securities and Exchange Commission (the "SEC"), generally monitors the payment of the Company's expenses and oversees the performance of administrative and professional services rendered by others. The Administrator has hired a third-party sub-administrator to assist with the provision of administrative services. The Company reimburses the Administrator for the Company's allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations to the Company under the Administration Agreement, including compensation of the Company's chief financial officer and chief compliance officer, and their respective staffs. Pursuant to the Administration Agreement and further restricted by the Company, the Administrator may, in its own discretion, submit to the Company for reimbursement some or all of the expenses that the Administrator has incurred on behalf of the Company during any quarterly period. As a result, the amount of expenses for which the Company will have to reimburse the Administrator may fluctuate in future quarterly periods and there can be no assurance given as to when, or if, the Administrator may determine to limit the expenses that the Administrator submits to the Company for reimbursement in the future. The Administrator cannot recoup any expenses that the Administrator has previously waived. For the three and six months ended June 30, 2025 approximately $182 and $337, respectively, of indirect administrative expenses were included in administrative expenses, none of which were waived by the Administrator. For the three and six months ended

54

June 30, 2024 approximately $139 and $287, respectively, of indirect administrative expenses were included in administrative expenses, of which $139 and $213, respectively, were waived by the Administrator. As of June 30, 2025 and December 31, 2024, approximately $167 and $147, respectively, of indirect administrative expenses were included in payable to affiliates.

The Company, the Investment Adviser and the Administrator have also entered into a Trademark License Agreement (as amended, the "Trademark License Agreement") with New Mountain Capital, pursuant to which New Mountain Capital has agreed to grant the Company, the Investment Adviser and the Administrator a non-exclusive, royalty-free license to use the "New Mountain Capital" name. Under the Trademark License Agreement, subject to certain conditions, the Company, the Investment Adviser and the Administrator will have a right to use the "New Mountain Capital" name, for so long as the Investment Adviser or one of its affiliates remains the investment adviser of the Company. Other than with respect to this limited license, the Company, the Investment Adviser and the Administrator will have no legal right to the "New Mountain Capital" name.

The Investment Adviser and its affiliates may also manage other funds in the future that may have investment mandates that are similar, in whole or in part, to the Company's investment mandate. The Investment Adviser and its affiliates may determine that an investment is appropriate for the Company or for one or more of those other funds. In such event, depending on the availability of such investment and other appropriate factors, the Investment Adviser or its affiliates may determine that the Company should invest side-by-side with one or more other funds. Any such investments will be made only to the extent permitted by applicable law and interpretive positions of the SEC and its staff and consistent with the Investment Adviser's allocation procedures. The Company may be prohibited under the 1940 Act from participating in certain transactions with its affiliates without prior approval of the directors who are not interested persons, and in some cases, the prior approval of the SEC. The Company, the Investment Adviser and certain of their affiliates were granted an order for exemptive relief that permitted co-investing with affiliates of the Company subject to various approvals of the Board and other conditions. On May 13, 2025, the Company, the Investment Adviser and certain of their affiliates were granted a new order for exemptive relief that superseded the prior order for exemptive relief (the “Exemptive Order”) by the SEC, that replaces the prior exemptive relief, for the Company to co-invest with other funds managed by the Investment Adviser or certain affiliates pursuant to the conditions of the Exemptive Order. Pursuant to such Exemptive Order, the Company generally is permitted to co-invest with certain of its affiliates if such co-investments are done on the same terms and at the same time, as further detailed in the Exemptive Order. The Exemptive Order requires that a “required majority” (as defined in Section 57(o) of the 1940 Act) of the Board makes certain findings (1) in most instances when the Company co-invests with its affiliates in an issuer where an affiliate of the Company has an existing investment in the issuer, and (2) if the Company disposes of an asset acquired in a transaction under the Exemptive Order unless the disposition is done on a pro rata basis. Pursuant to the Exemptive Order, the Board will oversee the Company’s participation in the co-investment program. As required by the Exemptive Order, the Company has adopted, and the Board has approved, policies and procedures reasonably designed to ensure compliance with the terms of the Exemptive Order, and the Investment Adviser and the Company’s Chief Compliance Officer will provide reporting to the Board.

On June 23, 2023, the Company entered into the Uncommitted Revolving Loan Agreement (as defined below) with NMF Investments III, L.L.C., an affiliate of the Investment Adviser, with a $10,000 maximum amount of revolver borrowings available and a maturity date of December 31, 2025. Refer to Note 6. Borrowings for discussion of the Unsecured Management Company Revolver (as defined below).

Note 6. Borrowings

Unsecured Management Company Revolver—The Uncommitted Revolving Loan Agreement, dated June 23, 2023, between the Company, as the borrower, and NMF Investments III, L.L.C., an affiliate of the Investment Adviser, as the lender (the "Uncommitted Revolving Loan Agreement"), is structured as a discretionary unsecured revolving credit facility (the "Unsecured Management Company Revolver"). The proceeds from the Unsecured Management Company Revolver may be used for general corporate purposes, including the funding of portfolio investments. The maturity date of the Unsecured Management Company Revolver is December 31, 2025 and the maximum facility amount is $10,000. The Unsecured Management Company Revolver generally bears interest at a rate of 7.00% per annum (as defined in the Uncommitted Revolving Loan Agreement).

For the three months ended June 30, 2025, interest expense and amortization of financing costs incurred on the Unsecured Management Company Revolver were $0 and $1 , respectively. For the six months ended June 30, 2025, interest expense and amortization of financing costs incurred on the Unsecured Management Company Revolver were $0 and $3, respectively. For the three months ended June 30, 2024, interest expense and amortization of financing costs incurred on the Unsecured Management Company Revolver were $0 and $2, respectively. For the six months ended June 30, 2024, interest expense and amortization of financing costs incurred on the Unsecured Management Company Revolver were $0 and $4, respectively.

As of June 30, 2025 and December 31, 2024, there was no outstanding balance under the Unsecured Management Company Revolver.

BMO Subscription Line—On June 29, 2023, the Company entered into a Loan Authorization Agreement with BMO Bank N.A. (formerly known as BMO Harris Bank N.A., "BMO") (as amended, from time to time, and most recently amended on April 12, 2024, the "Loan Authorization Agreement"), which allows the Company to borrow on a revolving credit basis an

55

aggregate principal amount which cannot exceed $75,000 (the "BMO Subscription Line"). All outstanding borrowings under the BMO Subscription Line are due on BMO's demand within 15 business days or the earliest to occur on the date (x) six months after each advance date and (y) 30 days prior to the termination of the Investment Period, which varies throughout the period. The BMO Subscription Line is collateralized by the unfunded Capital Commitments of each of the Company's unitholders. All fees associated with the origination and amendment of the BMO Subscription Line are capitalized on the Statements of Assets, Liabilities and Members' Capital and amortized and charged against income as other financing costs over the life of the BMO Subscription Line. The BMO Subscription Line bears interest at the greater of the prime commercial rate minus 0.25% per annum or the SOFR Quoted Rate (as defined below) for such day plus 2.50% per annum. SOFR Quoted Rate means as of any day of determination, 3-month Term SOFR on the date that is two U.S. Government Securities Business Days prior to such day of determination as such rate is published by the Term SOFR Administrator plus a credit spread adjustment of 0.15%. The BMO Subscription Line also charges an annual administrative fee, based on the Amount of Maximum Credit then in effect (as defined in the Loan Authorization Agreement).

The following table summarizes the interest expense, administrative fees and amortization of financing costs incurred on the BMO Subscription Line for the three and six months ended June 30, 2025 and June 30, 2024:

	Three Months Ended						Six Months Ended
	June 30, 2025			June 30, 2024			June 30, 2025			June 30, 2024
Interest expense	$	1,111		$	430		$	2,050		$	510
Administrative fees	$	—		$	208		$	(127)		$	226
Amortization of financing costs	$	(2)		$	110		$	79		$	148
Weighted average interest rate	7.3		%	8.3		%	7.3		%	8.3		%
Effective interest rate	7.2		%	14.4		%	7.1		%	14.3		%
Average debt outstanding	$	61,462		$	20,977		$	57,030		$	12,440

As of June 30, 2025 and December 31, 2024, the outstanding balance on the BMO Subscription Line was $18,000 and $58,000, respectively, and the Company was in compliance with the applicable covenants of the Loan Authorization Agreement on such dates.

Leverage risk factors—The Company intends to be generally unlevered during the course of its life (excluding borrowings under any subscription line secured by unfunded Capital Commitments and short-term working capital facilities) and will not incur leverage to the same extent as is customary for other business development companies, or for long-term investment purposes. Certain of the Company's lenders may have fixed dollar claims on the unfunded Capital Commitments of each of the Company's unitholders, and the Company would expect such lenders to seek recovery against these assets in the event of a default. The use of leverage also magnifies the potential for gain or loss on amounts invested. Leverage may magnify interest rate risk (particularly on the Company's fixed-rate investments), which is the risk that the prices of portfolio investments will fall or rise if market interest rates for those types of securities rise or fall. As a result, leverage may cause greater changes in the Company's members' capital. Similarly, leverage may cause a sharper decline in the Company's income than if the Company had not borrowed. Such a decline could negatively affect the Company's ability to make distributions to its unitholders. Leverage is generally considered a speculative investment technique. The Company's ability to service any debt incurred will depend largely on financial performance and will be subject to prevailing economic conditions and competitive pressures.

Note 7. Regulation

The Company has elected to be treated for U.S. federal income tax purposes as a RIC under Subchapter M of the Code and intends to comply with the requirements to continue to qualify and maintain its status as a RIC annually. In order to continue to qualify and be subject to tax treatment as a RIC for U.S. federal income tax purposes, among other things, the Company is generally required to timely distribute to its unitholders at least 90.0% of its investment company taxable income, as defined by the Code, for each year. The Company, among other things, intends to make and will continue to make the requisite timely distributions to its unitholders, and as such, the Company will generally be relieved from U.S. federal, state, and local income taxes (excluding excise taxes which may be imposed under the Code).

Additionally, as a BDC, the Company must not acquire any assets other than "qualifying assets" (as defined in Section 55(a) of the 1940 Act) unless, at the time the acquisition is made, at least 70.0% of its total assets are qualifying assets (with certain limited exceptions). In addition, the Company must offer to make available to all "eligible portfolio companies" (as defined in the 1940 Act) significant managerial assistance.

Note 8. Commitments and Contingencies

In the normal course of business, the Company may enter into contracts that contain a variety of representations and warranties and which provide general indemnifications. The Company may also enter into future funding commitments such as

56

revolving credit facilities, bridge financing commitments or delayed draw commitments. As of June 30, 2025, the Company had unfunded commitments on revolving credit facilities of $24,209, no outstanding bridge financing commitments and other future funding commitments of $57,759. As of December 31, 2024, the Company had unfunded commitments on revolving credit facilities of $21,164, no outstanding bridge financing commitments, and other future funding commitments of $56,815. The unfunded commitments on revolving credit facilities and delayed draws are disclosed on the Company's Schedules of Investments.

The Company also had revolving borrowings available under the Unsecured Management Company Revolver and BMO Subscription Line as of June 30, 2025 and December 31, 2024. See Note 6. Borrowings, for details.

The Company may from time to time enter into financing commitment letters. As of June 30, 2025 and December 31, 2024, the Company had commitment letters to purchase investments in the aggregate par amount of $22,264 and $13,473, respectively, which could require funding in the future.

Note 12. Recent Accounting Standards Updates

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (“ASU 2024-03”), which requires disaggregated disclosure of certain costs and expenses, including purchases of inventory, employee compensation, depreciation, amortization and depletion, within relevant income statement captions. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods beginning with the first quarter ending March 31, 2028. Early adoption and retrospective application is permitted. The Company is currently assessing the impact of this guidance, however, the Company does not expect a material impact on its consolidated financial statements.

Note 13. Segment Reporting

The Company operates through a single operating and reporting segment with an investment objective to generate both current income and capital appreciation through debt and equity investments. The chief operating decision maker ("CODM") is the Company’s Chief Executive Officer and the CODM assesses the performance and makes operating decisions of the Company on a consolidated basis primarily based on the Company’s net increase in unitholders’ equity resulting from operations (“net income”). In addition to numerous other factors and metrics, the CODM utilizes net income as a key metric in determining the amount of dividends to be distributed to the Company’s unitholders. As the Company’s operations are comprised of a single reporting segment, the segment assets are reflected on the accompanying statement of assets and liabilities as “total assets” and the significant segment expenses are listed on the accompanying statement of operations.

Note 14. Subsequent Events

The Company has evaluated the need for disclosures and/or adjustments resulting from recent developments through the date the financial statements were issued. There have been no recent developments that require recognition or disclosure in these financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the unitholders and the Board of Directors of New Mountain Guardian IV Income Fund, L.L.C.

Results of Review of Interim Financial Information

We have reviewed the accompanying statement of assets, liabilities and members’ capital of New Mountain Guardian IV Income Fund, L.L.C. (the "Company"), including the schedule of investments, as of June 30, 2025, the related statements of operations, and changes in members’ capital for the three-month and six-month periods ended June 30, 2025 and 2024, the statements of cash flows for the six-month periods ended June 30, 2025 and 2024 and the related notes (collectively referred to as the "interim financial information"). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the statement of assets, liabilities and members’ capital of the Company, including the schedule of investments as of December 31, 2024, and the related statements of operations, changes in members’ capital and cash flows for the year then ended (not presented herein); and in our report dated March 5, 2025, we expressed an unqualified opinion on those financial statements. In our opinion, the information set forth in the accompanying statement of assets, liabilities and members’ capital as of December 31, 2024, is fairly stated, in all material respects, in relation to the statement of assets, liabilities and members’ capital from which it has been derived.

Basis for Review Results

This interim financial information is the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company 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 reviews in accordance with standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Overview

We are a Delaware limited liability company formed on November 4, 2022. We are a closed-end, non-diversified management investment company that has elected to be regulated as a business development company ("BDC") under the Investment Company Act of 1940, as amended (the "1940 Act"). We have elected to be treated for U.S. federal income tax purposes, and intend to comply with the requirements to continue to qualify annually, as a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code").

The Investment Adviser is a wholly-owned subsidiary of New Mountain Capital. New Mountain Capital is a global investment firm with over $55 billion of assets under management and a track record of investing in the middle market. New Mountain Capital focuses on investing in defensive growth companies across its private equity, credit and net lease investment strategies. The Investment Adviser manages our day-to-day operations and provides us with investment advisory and management services. The Investment Adviser also manages other funds that may have investment mandates that are similar, in whole or in part, to ours. New Mountain Finance Administration, L.L.C. (the "Administrator"), a wholly-owned subsidiary of

61

New Mountain Capital, provides the administrative services necessary to conduct our day-to-day operations. The Administrator has hired a third-party sub-administrator to assist with the provision of administrative services.

We conducted a private offering (the "Private Offering") of units of our limited liability company interests (the "Units") to investors in reliance on exemptions from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). Units were offered for subscription continuously throughout the Closing Period (as defined below). Each investor in the Private Offering made a capital commitment (each, a "Capital Commitment") to purchase Units pursuant to a subscription agreement entered into with us (each, a "Subscription Agreement"). Closings of the Private Offering occurred, from time to time, in the Investment Adviser's sole discretion, during the 18-month period (the "Closing Period") following the initial closing of Capital Commitments, which occurred on May 23, 2023. On November 20, 2024, pursuant to the limited liability company agreement as amended and restated on July, 10, 2024 (the "A&R LLC Agreement"), the Investment Adviser elected to extend the Closing Period from November 23, 2024 to March 31, 2025. At the end of the Closing Period, we had aggregate Capital Commitments from investors of $512.4 million. We accepted and drew down on Capital Commitments from investors throughout the Closing Period and may draw down on Capital Commitments after the Closing Period. We commenced our loan origination and investment activities on May 24, 2023. The investment period began on May 23, 2023 and will continue until March 31, 2029, the four-year anniversary of the end of the Closing Period (the "Investment Period"). Our term is until March 31, 2031, six years from the end of the Closing Period, subject to (i) a one year extension as determined by the Investment Adviser in its sole discretion and (ii) an additional one year extension as determined by our board of directors.

We focus on providing direct lending solutions to U.S. upper middle market companies backed by top private equity sponsors. Our investment objective is to generate current income and capital appreciation through the sourcing and origination of senior secured loans and select junior capital positions, to growing businesses in defensive industries that offer attractive risk-adjusted returns. Our differentiated investment approach leverages the deep sector knowledge and operating resources of New Mountain Capital.

We primarily invest in senior secured debt of U.S. sponsor-backed, middle market companies. We define middle market companies as those with annual earnings before interest, taxes, depreciation and amortization ("EBITDA") of $10.0 million to $200.0 million. Our focus is on defensive growth businesses that generally exhibit the following characteristics: (i) acyclicality, (ii) sustainable secular growth drivers, (iii) niche market dominance and high barriers to competitive entry, (iv) recurring revenue and strong free cash flow, (v) flexible cost structures and (vi) seasoned management teams.

Senior secured loans may include traditional first lien loans or unitranche loans. We invest a significant portion of our portfolio in unitranche loans, which are loans that combine both senior and subordinated debt, generally in a first-lien position. Because unitranche loans combine characteristics of senior and subordinated debt, they have risks similar to the risks associated with secured debt and subordinated debt. Certain unitranche loan investments may include “last-out” positions, which generally heighten the risk of loss. In some cases, our investments may also include equity interests.

As of June 30, 2025, our top five industry concentrations were software, business services, healthcare, financial services and education.

As of June 30, 2025, our members' capital was approximately $383.0 million and our portfolio had a fair value of approximately $409.4 million in 107 portfolio companies.

Critical Accounting Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the following items as critical accounting estimates.

Basis of Accounting

We are an investment company following accounting and reporting guidance as described in Accounting Standards Codification Topic 946, Financial Services—Investment Companies ("ASC 946").

Valuation and Leveling of Portfolio Investments

At all times, consistent with GAAP and the 1940 Act, we conduct a valuation of our assets, which impacts our members' capital.

We value our assets on a quarterly basis, or more frequently if required under the 1940 Act. In all cases, our board of directors is ultimately and solely responsible for determining the fair value of our portfolio investments on a quarterly basis in good faith, including investments that are not publicly traded, those whose market prices are not readily available and any other

62

situation where our portfolio investments require a fair value determination. Security transactions are accounted for on a trade date basis. Our quarterly valuation procedures are set forth in more detail below:

(1)Investments for which market quotations are readily available on an exchange are valued at such market quotations based on the closing price indicated from independent pricing services.

(2)Investments for which indicative prices are obtained from various pricing services and/or brokers or dealers are valued through a multi-step valuation process, as described below, to determine whether the quote(s) obtained is representative of fair value in accordance with GAAP.

a.    Bond quotes are obtained through independent pricing services. Internal reviews are performed by the investment professionals of the Investment Adviser to ensure that the quote obtained is representative of fair value in accordance with GAAP and, if so, the quote is used. If the Investment Adviser is unable to sufficiently validate the quote(s) internally and if the investment's par value or its fair value exceeds the materiality threshold, the investment is valued similarly to those assets with no readily available quotes (see (3) below); and

b.    For investments other than bonds, we look at the number of quotes readily available and perform the following procedures:

i.    Investments for which two or more quotes are received from a pricing service are valued using the mean of the mean of the bid and ask of the quotes obtained. We will evaluate the reasonableness of the quote, and if the quote is determined to not be representative of fair value, we will use one or more of the methodologies outlined below to determine fair value; and

ii.    Investments for which one quote is received from a pricing service are validated internally. The investment professionals of the Investment Adviser analyze the market quotes obtained using an array of valuation methods (further described below) to validate the fair value. If the Investment Adviser is unable to sufficiently validate the quote internally and if the investment's par value or its fair value exceeds the materiality threshold, the investment is valued similarly to those assets with no readily available quotes (see (3) below).

(3)Investments for which quotations are not readily available through exchanges, pricing services, brokers or dealers are valued through a multi-step valuation process:

a.    Each portfolio company or investment is initially valued by the investment professionals of the Investment Adviser responsible for the credit monitoring;

b.    Preliminary valuation conclusions will then be documented and discussed with our senior management;

c.    If an investment falls into (3) above for four consecutive quarters and if the investment's par value or its fair value exceeds the materiality threshold, then at least once each fiscal year, the valuation for each portfolio investment for which we do not have a readily available market quotation will be reviewed by an independent valuation firm engaged by our board of directors; and

d.    When deemed appropriate by our management, an independent valuation firm may be engaged to review and value investment(s) of a portfolio company, without any preliminary valuation being performed by the Investment Adviser. The investment professionals of the Investment Adviser will review and validate the value provided.

For investments in revolving credit facilities and delayed draw commitments, the cost basis of the funded investments purchased is offset by any costs/netbacks received for any unfunded portion on the total balance committed. The fair value is also adjusted for the price appreciation or depreciation on the unfunded portion. As a result, the purchase of a commitment not completely funded may result in a negative fair value until it is called and funded.

The values assigned to investments are based upon available information and do not necessarily represent amounts which might ultimately be realized, since such amounts depend on future circumstances and cannot be reasonably determined until the individual positions are liquidated. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments may fluctuate from period to period and the fluctuations could be material.

GAAP fair value measurement guidance classifies the inputs used in measuring fair value into three levels as follows:

Level I—Quoted prices (unadjusted) are available in active markets for identical investments and we have the ability to access such quotes as of the reporting date. The type of investments which would generally be included in Level I include active exchange-traded equity securities and exchange-traded derivatives. As required by Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures ("ASC 820"), we, to the extent that we hold such investments, do not

63

adjust the quoted price for these investments, even in situations where we hold a large position and a sale could reasonably impact the quoted price.

Level II—Pricing inputs are observable for the investments, either directly or indirectly, as of the reporting date, but are not the same as those used in Level I. Level II inputs include the following:

•Quoted prices for similar assets or liabilities in active markets;

•Quoted prices for identical or similar assets or liabilities in non-active markets (examples include corporate and municipal bonds, which trade infrequently);

•Pricing models whose inputs are observable for substantially the full term of the asset or liability (examples include most over-the-counter derivatives, including foreign exchange forward contracts); and

•Pricing models whose inputs are derived principally from or corroborated by observable market data through correlation or other means for substantially the full term of the asset or liability.

Level III—Pricing inputs are unobservable for the investment and include situations where there is little, if any, market activity for the investment.

The inputs used to measure fair value may fall into different levels. In all instances when the inputs fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level of input that is significant to the fair value measurement in its entirety. As such, a Level III fair value measurement may include inputs that are both observable and unobservable. Gains and losses for such assets categorized within the Level III table below may include changes in fair value that are attributable to both observable inputs and unobservable inputs.

The inputs into the determination of fair value require significant judgment or estimation by management and consideration of factors specific to each investment. A review of the fair value hierarchy classifications is conducted on a quarterly basis. Changes in the observability of valuation inputs may result in the transfer of certain investments within the fair value hierarchy from period to period.

See Item 1.—Financial Statements—Note 4. Fair Value in this Quarterly Report on Form 10-Q for additional information on fair value hierarchy as of June 30, 2025.

We generally use the following framework when determining the fair value of investments where there is little, if any, market activity or observable pricing inputs. We typically determine the fair value of our performing debt investments utilizing an income approach. Additional consideration is given using a market based approach, as well as reviewing the overall underlying portfolio company's performance and associated financial risks. The following outlines additional details on the approaches considered:

Company Performance, Financial Review, and Analysis:   Prior to investment, as part of our due diligence process, we evaluate the overall performance and financial stability of the portfolio company. Post investment, we analyze each portfolio company's current operating performance and relevant financial trends versus prior year and budgeted results, including, but not limited to, factors affecting its revenue and EBITDA growth, margin trends, liquidity position, covenant compliance and changes to its capital structure. We also attempt to identify and subsequently track any developments at the portfolio company, within its customer or vendor base or within the industry or the macroeconomic environment, generally, that may alter any material element of our original investment thesis. This analysis is specific to each portfolio company. We leverage the knowledge gained from our original due diligence process, augmented by this subsequent monitoring, to continually refine our outlook for each of our portfolio companies and ultimately form the valuation of our investment in each portfolio company. When an external event such as a purchase transaction, public offering or subsequent sale occurs, we will consider the pricing indicated by the external event to corroborate the private valuation.

For debt investments, we may employ the Market Based Approach (as described below) to assess the total enterprise value of the portfolio company, in order to evaluate the enterprise value coverage of our debt investment. For equity investments or in cases where the Market Based Approach implies a lack of enterprise value coverage for the debt investment, we may additionally employ a discounted cash flow analysis based on the free cash flows of the portfolio company to assess the total enterprise value. After enterprise value coverage is demonstrated for our debt investments through the method(s) above, the Income Based Approach (as described below) may be employed to estimate the fair value of the investment.

Market Based Approach:    We may estimate the total enterprise value of each portfolio company by utilizing EBITDA or revenue multiples of publicly traded comparable companies and comparable transactions. We consider numerous factors when selecting the appropriate companies whose trading multiples are used to value our portfolio companies. These factors include, but are not limited to, the type of organization, similarity to the business being valued, and relevant risk factors, as well as size, profitability and growth expectations. We may apply an average of various relevant comparable company EBITDA or revenue multiples to the portfolio company's latest twelve month ("LTM") EBITDA or revenue or projected

64

EBITDA or revenue to calculate the enterprise value of the portfolio company. Significant increases or decreases in the EBITDA or revenue multiples will result in an increase or decrease in enterprise value, which may result in an increase or decrease in the fair value estimate of the investment.

Income Based Approach:    We also may use a discounted cash flow analysis to estimate the fair value of the investment. Projected cash flows represent the relevant security's contractual interest, fee and principal payments plus the assumption of full principal recovery at the investment's expected maturity date. These cash flows are discounted at a rate established utilizing a combination of a yield calibration approach and a comparable investment approach. The yield calibration approach incorporates changes in the credit quality (as measured by relevant statistics) of the portfolio company, as compared to changes in the yield associated with comparable credit quality market indices, between the date of origination and the valuation date. The comparable investment approach utilizes an average yield-to-maturity of a selected set of high-quality, liquid investments to determine a comparable investment discount rate. Significant increases or decreases in the discount rate would result in a decrease or increase in the fair value measurement.

See Item 1.—Financial Statements—Note 4. Fair Value in this Quarterly Report on Form 10-Q for additional information on unobservable inputs used in the fair value measurement of our Level III investments as of June 30, 2025.

Revenue Recognition

Sales and paydowns of investments: Realized gains and losses on investments are determined on the specific identification method.

Interest and dividend income: Interest income, including amortization of premium and discount using the effective interest method, is recorded on the accrual basis and periodically assessed for collectability. Interest income also includes interest earned from cash on hand. Upon the prepayment of a loan or debt security, any prepayment penalties are recorded as part of interest income. We have loans and certain preferred equity investments in the portfolio that contain a payment-in-kind ("PIK") interest or dividend provision. PIK interest and dividends are accrued and recorded as income at the contractual rates, if deemed collectible. The PIK interest and dividends are added to the principal balance on the capitalization date and are generally due at maturity or when redeemed by the issuer. For the three and six months ended June 30, 2025, we recognized PIK interest from investments of $0.2 million and $0.4 million, respectively, and PIK dividends from investments of less than $50 thousand and approximately $52 thousand, respectively. For the three and six months ended June 30, 2024, we recognized PIK interest from investments of $0.3 million and $0.4 million, respectively, and no PIK dividends from investments.

Dividend income on preferred securities is recorded as dividend income on an accrual basis to the extent that such amounts are deemed collectible.

Non-accrual income: Investments are placed on non-accrual status when principal or interest payments are past due for 30 days or more and when there is reasonable doubt that principal or interest will be collected. Accrued cash and un-capitalized PIK interest or dividends are reversed when an investment is placed on non-accrual status. Previously capitalized PIK interest or dividends are not reversed when an investment is placed on non-accrual status. Interest or dividend payments received on non-accrual investments may be recognized as income or applied to principal depending upon management's judgment of the ultimate collectability. Non-accrual investments are restored to accrual status when past due principal and interest is paid and, in management's judgment, are likely to remain current. As of June 30, 2025 and December 31, 2024, no investments were on non-accrual status.

Fee income: Fee income represents delayed compensation, revolver fees, upfront fees, amendment fees and other miscellaneous fees received and are typically non-recurring in nature. Delayed compensation is income earned from counterparties on trades that do not settle within a set number of business days after the trade date. Fee income may also include fees from bridge loans. We may from time to time enter into bridge financing commitments, an obligation to provide interim financing to a counterparty until permanent credit can be obtained. These commitments are short-term in nature and may expire unfunded. A fee is received by us for providing such commitments. Structuring fees and upfront fees are recognized as income when earned, usually when paid at the closing of the investment, and are non-refundable.

Monitoring of Portfolio Investments

We monitor the performance and financial trends of our portfolio companies on at least a quarterly basis. We attempt to identify any developments within the portfolio company, the industry or the macroeconomic environment that may alter any material element of our original investment strategy. Our portfolio monitoring procedures are designed to provide a simple yet comprehensive analysis of our portfolio companies based on their operating performance and underlying business characteristics, which in turn forms the basis of its Risk Rating (as defined below).

We use an investment risk rating system to characterize and monitor the credit profile and expected level of returns on each investment in the portfolio. As such, we assign each investment a composite score ("Risk Rating") based on two metrics – 1) Operating Performance and 2) Business Characteristics:

65

•Operating Performance assesses the health of the investment in context of its financial performance and the market environment it faces. The metric is expressed in Tiers of "4" to "1", with "4" being the best and "1" being the worst:

◦Tier 4 – Business performance is in-line with or above expectations

◦Tier 3 – Moderate business underperformance and/or moderate market headwinds

◦Tier 2 – Significant business underperformance and/or significant market headwinds

◦Tier 1 – Severe business underperformance and/or severe market headwinds

•Business Characteristics assesses the health of the investment in context of the underlying portfolio company's business and credit quality, the underlying portfolio company's current balance sheet, and the level of support from the equity sponsor. The metric is expressed as on a qualitative scale of "A" to "C", with "A" being the best and "C" being the worst.

The Risk Rating for each investment is a composite of these two metrics. The Risk Rating is expressed in categories of Green, Yellow, Orange and Red, with Green reflecting an investment that is in-line with or above expectations and Red reflecting an investment performing materially below expectations. The mapping of the composite scores to these categories are below:

•Green – 4C, 3B, 2A, 4B, 3A, and 4A (e.g., Tier 4 for Operating Performance and C for Business Characteristics)

•Yellow – 3C, 2B, and 1A

•Orange – 2C and 1B

•Red – 1C

The following table shows the Risk Ratings of our portfolio companies as of June 30, 2025:

(in millions)	As of June 30, 2025
Risk Rating	Cost		Percent		Fair Value		Percent
Green	$	407.7	99.5	%	$	407.4	99.5	%
Yellow	2.1		0.5	%	2.0		0.5	%
Orange	—		—	%	—		—	%
Red	—		—	%	—		—	%
	$	409.8	100.0	%	$	409.4	100.0	%

As of June 30, 2025, all investments in our portfolio had a Green Risk Rating, with the exception of one portfolio company that had a Yellow Risk Rating.

Portfolio and Investment Activity

The fair value of our investments, as determined in good faith by our board of directors, was approximately $409.4 million in 107 portfolio companies at June 30, 2025 and approximately $377.8 million in 99 portfolio companies at December 31, 2024.

The following table shows our portfolio and investment activity for the six months ended June 30, 2025 and June 30, 2024:

	Six Months Ended
(in millions)	June 30, 2025		June 30, 2024
Investments in 53 and 62, respectively, new and existing portfolio companies	$	73.5	165.2

Results of Operations for the Three Months Ended June 30, 2025 and June 30, 2024

Revenue

	Three Months Ended
(in thousands)	June 30, 2025		June 30, 2024
Total interest income	$	10,402	$	5,211
Dividend income	118		—
Fee income	259		581
Total investment income	$	10,779	$	5,792

Our total investment income increased by approximately $5.0 million, or 86% for the three months ended June 30, 2025 as compared to the three months ended June 30, 2024. For the three months ended June 30, 2025, total investment income of approximately $10.8 million consisted of approximately $9.3 million in cash interest from investments, approximately $0.2 million in PIK and non-cash interest from investments, net amortization of purchase premiums and discounts of approximately $0.9 million, approximately $0.1 million in dividends from investments and approximately $0.3 million in fee income.

The increase in interest income of approximately $5.2 million during the three months ended June 30, 2025 as compared to the three months ended June 30, 2024 was primarily attributable to our deployment of capital and increasing invested balances during the period. Fee income during the three months ended June 30, 2025, which represents fees that are generally non-recurring in nature, was primarily attributable to upfront fees received from 8 portfolio companies.

    Our total net operating expenses increased by approximately $1.3 million for the three months ended June 30, 2025 as compared to the three months ended June 30, 2024. Our management fee net of waivers increased by approximately $0.5 million and our income based incentive fee increased by approximately $0.4 million for the three months ended June 30, 2025 as compared to the three months ended June 30, 2024. Per the Investment Management Agreement (as defined below), the management fee was reduced by 50% until the one-year anniversary of the Initial Drawdown Date (as defined in the Investment Management Agreement). The base management fee may also be reduced by placement fees and a voluntary fee waiver made by the Investment Adviser. The increase in management fees and income based incentive fees was attributable to larger managed and invested capital balances over the three months ended June 30, 2025 as compared to the three months ended June 30, 2024 and the expiration of the 50% management fee waiver on May 31, 2024. Our capital gains incentive fees decreased by approximately $30.0 thousand for the three months ended June 30, 2025 as compared to the three months ended June 30, 2024. The decrease in capital gains incentive fees was due to the reduction of the accrual for hypothetical gains recognized as if the portfolio was sold at fair value in accordance with GAAP which was driven by the net depreciation on the portfolio for the three months ended June 30, 2025. The accrual for any capital gains incentive fee under GAAP in a given period may result in an additional expense if such cumulative amount is greater than the cumulative amount in the prior period or a reduction of previously recorded expense if such cumulative amount is less than the amount in the prior period. If such cumulative amount is negative, then there is no accrual. Amounts accrued are not payable unless gains are realized and distributions are greater than contributions.

Interest and other financing expenses increased by approximately $0.4 million during the three months ended June 30, 2025 as compared to three months ended June 30, 2024, primarily due to higher drawn balances on our BMO Subscription Line.

Our total administrative expenses, professional fees and other general and administrative expenses remained relatively flat during the three months ended June 30, 2025 as compared to the three months ended June 30, 2024.

Net Realized Gains (Losses) and Net Change in Unrealized Appreciation (Depreciation)

Net change in unrealized appreciation (depreciation) of investments	(1,597)		(7)
Net realized and unrealized gain (losses)	$	(1,608)	$	(3)

We had net realized losses and net unrealized depreciation which resulted in a net loss of approximately $1.6 million for the three months ended June 30, 2025 as compared to net realized gain and unrealized depreciation resulting in a net loss of approximately $3.0 thousand for the three months ended June 30, 2024. As movement in unrealized appreciation or depreciation can be the result of realizations, we look at net realized and unrealized gains or losses together. The net loss for the three months ended June 30, 2025 was primarily driven by the overall decrease in market prices of our investments during the period and material accelerated amortization realized on our investment in Sierra Enterprises, LLC due to early repayments

made. The net loss for the three months ended June 30, 2024 was primarily driven by the slight decrease in market prices of our investments during the period.

Results of Operations for the Six Months Ended June 30, 2025 and June 30, 2024

Revenue

	Six Months Ended
(in thousands)	June 30, 2025		June 30, 2024
Total interest income	$	19,984	$	8,453
Dividend income	233		—
Fee income	594		1,039
Total investment income	$	20,811	$	9,492

Our total investment income increased by approximately $11.3 million, or 119% for the six months ended June 30, 2025 as compared to the six months ended June 30, 2024. For the six months ended June 30, 2025, total investment income of approximately $20.8 million consisted of approximately $18.4 million in cash interest from investments, approximately $0.4 million in PIK and non-cash interest from investments, net amortization of purchase premiums and discounts of approximately $1.2 million, approximately $0.2 million in dividends from investments and approximately $0.6 million in fee income.

The increase in interest income of approximately $11.5 million during the six months ended June 30, 2025 as compared to the six months ended June 30, 2024 was primarily attributable to our deployment of capital and increasing invested balances during the period. Fee income during the six months ended June 30, 2025, which represents fees that are generally non-recurring in nature, was primarily attributable to upfront, amendment and ticking fees received from 17 portfolio companies.

    Our total net operating expenses increased by approximately $3.0 million for the six months ended June 30, 2025 as compared to the six months ended June 30, 2024. Our management fee net of waivers increased by approximately $1.1 million and our income based incentive fee increased by approximately $0.9 million for the six months ended June 30, 2025 as compared to the six months ended June 30, 2024. Per the Investment Management Agreement (as defined below), the base management fee was reduced by 50% until the one-year anniversary of the Initial Drawdown Date (as defined in the Investment Management Agreement). The base management fee may also be reduced by placement fees and a voluntary fee waiver made by the Investment Adviser. The increase in management fees and income based incentive fees was attributable to larger managed and invested capital balances over the six months ended June 30, 2025 as compared to the six months ended June 30, 2024 and the expiration of the 50% base management fee waiver on May 31, 2024. Our capital gains incentive fees decreased by approximately $0.1 million for the six months ended June 30, 2025 as compared to the six months ended June 30, 2024. The decrease in capital gains incentive fees was due to the reduction of the accrual for hypothetical gains recognized as if the portfolio was sold at fair value in accordance with GAAP which was driven by the net depreciation on the portfolio for the six months ended June 30, 2025. The accrual for any capital gains incentive fee under GAAP in a given period may result in an

additional expense if such cumulative amount is greater than the cumulative amount in the prior period or a reduction of previously recorded expense if such cumulative amount is less than the amount in the prior period. If such cumulative amount is negative, then there is no accrual. Amounts accrued are not payable unless gains are realized and distributions are greater than contributions.

Interest and other financing expenses increased by approximately $1.1 million during the six months ended June 30, 2025 as compared to six months ended June 30, 2024, primarily due to higher drawn balances on our BMO Subscription Line.

Our total administrative expenses, professional fees and other general and administrative expenses remained relatively flat during the six months ended June 30, 2025 as compared to the six months ended June 30, 2024.

We had net realized losses and net unrealized depreciation which resulted in a net loss of approximately $2.5 million for the six months ended June 30, 2025 as compared to a net realized gain and unrealized appreciation resulting in a net gain of approximately $0.5 million for the six months ended June 30, 2024. As movement in unrealized appreciation or depreciation can be the result of realizations, we look at net realized and unrealized gains or losses together. The net loss for the six months ended June 30, 2025 was primarily driven by the overall decrease in market prices of our investments during the period and material accelerated amortization realized on our investment in Sierra Enterprises, LLC due to early repayments made. The net gain for the six months ended June 30, 2024 was primarily driven by the overall increase in market prices of our investments during the period.

Liquidity, Capital Resources, Off-Balance Sheet Arrangements, Borrowings and Contractual Obligations

Liquidity and Capital Resources

The primary use of existing funds and any funds raised in the future is expected to be for investments in portfolio companies, repayment of indebtedness, cash distributions to our unitholders or for other general corporate purposes.

We expect to generate cash from (1) drawing down capital in respect of our Units, (2) cash flows from investments and operations and (3) borrowings from banks or other lenders. We will seek to enter into any bank debt, credit facility or other financing arrangements on at least customary market terms, however, we cannot assure you we will be able to do so. Any such incurrence or issuance would be subject to prevailing market conditions, our liquidity requirements, contractual and regulatory restrictions and other factors. Upon organization, we adopted the application of the modified asset coverage requirements set forth in Section 61(a) of the 1940 Act, as amended by the Small Business Credit Availability Act, which resulted in the reduction of the minimum asset coverage ratio applicable to us from 200.0% to 150.0%. In connection with their subscriptions for our Units, our unitholders were required to acknowledge our ability to operate with an asset coverage ratio that may be as low as 150.0%. In accordance with the 1940 Act, with certain limited exceptions, we are only allowed to borrow amounts such that our asset coverage, calculated pursuant to the 1940 Act, is at least 150.0% after such borrowing (which means we can borrow $2 for every $1 of our equity). As of June 30, 2025, our asset coverage ratio was 2,228.0%.

Since our inception on November 4, 2022, we have entered into Subscription Agreements with several investors on various dates during the Closing Period. Closings of the Private Offering occurred, from time to time, in the Investment Adviser's sole discretion, during the Closing Period. On June 30, 2025 and December 31, 2024, we had aggregate capital commitments accepted and undrawn capital commitments from investors as follows:

(in millions)	June 30, 2025			December 31, 2024
Capital Commitments	$	512.4		$	512.4
Unfunded Capital Commitments	128.1			179.3
% of Capital Commitments funded	75.0		%	65.0		%

As of June 30, 2025 and December 31, 2024, our credit facilities consisted of the BMO Subscription Line and Unsecured Management Company Revolver. See Item 1—Financial Statements—Note 6. Borrowings in this Quarterly Report on Form 10-Q for additional information.

As of June 30, 2025 and December 31, 2024, we had cash and cash equivalents of approximately $8.2 million and $19.6 million, respectively. Our cash used in operating activities for the six months ended June 30, 2025 and June 30, 2024 was

70

approximately $15.2 million and $117.2 million, respectively. We expect that all current liquidity needs will be met with cash flows from drawdowns on Capital Commitments, investments and operations and borrowings from banks or other lenders.

Off-Balance Sheet Arrangements

We may become a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financial needs of our portfolio companies. These instruments may include commitments to extend credit and involve, to varying degrees, elements of liquidity and credit risk in excess of the amount recognized on the balance sheet. As of June 30, 2025 and December 31, 2024, we had outstanding commitments to third parties to fund investments totaling $82.0 million and $78.0 million, respectively, under various undrawn revolving credit facilities, delayed draw commitments or other future funding commitments.

We may from time to time enter into financing commitment letters or bridge financing commitments, which could require funding in the future. As of June 30, 2025 and December 31, 2024, we had commitment letters to purchase investments in the aggregate par amount of $22.3 million and $13.5 million, respectively, which could require funding in the future. As of June 30, 2025 and December 31, 2024, we had not entered into any bridge financing commitments which could require funding in the future.

Contractual Obligations

A summary of our significant contractual payment obligations as of June 30, 2025 is as follows:

	Contractual Obligations Payments Due by Period
(in millions)	Total		Less than 1 Year		1 - 3 Years		3 - 5 Years		More than 5 Years
BMO Subscription Line (1)	$	18.0	$	18.0	$	—	$	—	$	—
Unsecured Management Company Revolver (2)	—		—		—		—		—

(1)Under the terms of the BMO Subscription Line, all outstanding borrowings under that facility ($18.0 million as of June 30, 2025) are due on BMO's demand within 15 business days, or on the date 6 months after each advance date, which varies throughout the period. The BMO Subscription Line will terminate when all Capital Commitments have been funded. See Item 1—Financial Statements—Note 6. Borrowings in this Quarterly Report on Form 10-Q for material details on the BMO Subscription Line.

(2)Under the terms of the $10.0 million Unsecured Management Company Revolver, all outstanding borrowings under that facility ($0.0 million as of June 30, 2025) must be repaid on or before December 31, 2025. As of June 30, 2025, there was approximately $10.0 million of possible capacity remaining under the Unsecured Management Company Revolver. See Item 1—Financial Statements—Note 6. Borrowings in this Quarterly Report on Form 10-Q for material details on the Unsecured Management Company Revolver.

We have entered into an investment advisory and management agreement (the "Investment Management Agreement") with the Investment Adviser in accordance with the 1940 Act. Under the Investment Management Agreement, the Investment Adviser has agreed to provide us with investment advisory and management services. We have agreed to pay for these services (1) a management fee and (2) an incentive fee based on our performance.    

We have also entered into an administration agreement (the "Administration Agreement"), with the Administrator. Under the Administration Agreement, the Administrator arranges office space for us and provides office equipment and clerical, bookkeeping and record keeping services and other administrative services necessary to conduct our day-to-day operations. The Administrator also maintains, or oversees the maintenance of, our financial records, our reports to unitholders and reports filed with the SEC. The Administrator has hired a third-party sub-administrator to assist with the provision of administrative services.

If any of the contractual obligations discussed above are terminated, our costs under any new agreements that are entered into may increase. In addition, we would likely incur significant time and expense in locating alternative parties to provide the services we expect to receive under the Investment Management Agreement and the Administration Agreement.

Distributions and Dividends

Distributions declared to unitholders for the six months ended June 30, 2025 totaled approximately $14.9 million.

Tax characteristics of all distributions paid are reported to unitholders on Form 1099 or Form 1042 after the end of the calendar year. For the year ended December 31, 2024 and for the period from May 24, 2023 (commencement of operations) to

71

December 31, 2023, total distributions declared were $19.6 million and $1.7 million, respectively, of which the distributions were comprised of approximately 97.19% and 99.62%, respectively, of ordinary income, 1.68% and 0.00%, respectively, of long-term capital gains and 1.13% and 0.38%, respectively, of a return of capital. Future quarterly distributions, if any, will be determined by our board of directors.

We intend to pay quarterly distributions to our unitholders in amounts sufficient to qualify as and maintain our status as a RIC. We intend to distribute approximately all of our net investment income on a quarterly basis and substantially all of our taxable income on an annual basis, except that we may retain certain net capital gains for reinvestment.    

Related Parties

We have entered into a number of business relationships with affiliated or related parties, including the following:

•We have entered into the Investment Management Agreement with the Investment Adviser, a wholly-owned subsidiary of New Mountain Capital. Therefore, New Mountain Capital is entitled to any profits earned by the Investment Adviser, which includes any fees payable to the Investment Adviser under the terms of the Investment Management Agreement, less expenses incurred by the Investment Adviser in performing its services under the Investment Management Agreement.

•We have entered into the Expense Limitation and Reimbursement Agreement with the Investment Adviser. The Investment Adviser has agreed to reduce and/or waive its management fee (the "Specified Expenses Cap") each year such that we will not be required to pay certain expenses in excess of a maximum aggregate amount defined in the Expense Limitation and Reimbursement Agreement.

•We have entered into the Administration Agreement with the Administrator, a wholly-owned subsidiary of New Mountain Capital. The Administrator arranges our office space and provides office equipment and administrative services necessary to conduct our day-to-day operations pursuant to the Administration Agreement. The Administrator has hired a third-party sub-administrator to assist with the provision of administrative services. We reimburse the Administrator for the allocable portion of overhead and other expenses incurred by it in performing its obligations to us under the Administration Agreement, which includes the fees and expenses associated with performing administrative, finance and compliance functions, and the compensation of our chief financial officer and chief compliance officer and their respective staffs. Pursuant to the Administration Agreement and further restricted by us, the Administrator may, in its own discretion, submit to us for reimbursement some or all of the expenses that the Administrator has incurred on our behalf during any quarterly period. As a result, the amount of expenses for which we will have to reimburse the Administrator may fluctuate in future quarterly periods and there can be no assurance given as to when, or if, the Administrator may determine to limit the expenses that the Administrator submits to us for reimbursement in the future. The Administrator cannot recoup any expenses that the Administrator has previously waived. For the three and six months ended June 30, 2025, approximately $0.1 million and $0.3 million of indirect administrative expenses were included in administrative expenses, none of which was waived by the Administrator. As of June 30, 2025, $0.2 million of indirect administrative expenses were included in payable to affiliates on the Statement of Assets, Liabilities and Members' Capital.

•We, the Investment Adviser and the Administrator have entered into a royalty-free Trademark License Agreement with New Mountain Capital, pursuant to which New Mountain Capital has agreed to grant us, the Investment Adviser and the Administrator a non-exclusive, royalty-free license to use the name "New Mountain Capital".

In addition, we have adopted a formal code of ethics that governs the conduct of our officers and directors. These officers and directors also remain subject to the duties imposed by the 1940 Act and the Delaware Limited Liability Company Act.

The Investment Adviser and its affiliates may also manage other funds in the future that may have investment mandates that are similar, in whole or in part, to our investment mandates. The Investment Adviser and its affiliates may determine that an investment is appropriate for us and for one or more of those other funds. In such event, depending on the availability of such investment and other appropriate factors, the Investment Adviser or its affiliates may determine that we should invest side-by-side with one or more other funds. Any such investments will be made only to the extent permitted by applicable law and interpretive positions of the SEC and its staff, and consistent with the Investment Adviser's allocation procedures. We may be prohibited under the 1940 Act from participating in certain transactions with our affiliates without prior approval of the directors who are not interested persons, and in some cases, the prior approval of the SEC. We, the Investment Adviser and certain of their affiliates were granted an order for exemptive relief that permitted co-investing with our affiliates subject to various approvals of the Board and other conditions. On May 13, 2025, we, the Investment Adviser and certain of their affiliates were granted a new order for exemptive relief that superseded the prior order for exemptive relief (the “Exemptive Order”) by the SEC, that replaces the prior exemptive relief, for us to co-invest with other funds managed by the Investment Adviser or certain affiliates pursuant to the conditions of the Exemptive Order. Pursuant to such Exemptive Order,

72

we generally are permitted to co-invest with certain of our affiliates if such co-investments are done on the same terms and at the same time, as further detailed in the Exemptive Order. The Exemptive Order requires that a “required majority” (as defined in Section 57(o) of the 1940 Act) of the Board make certain findings (1) in most instances when we co-invest with our affiliates in an issuer where our affiliate has an existing investment in the issuer, and (2) if we dispose of an asset acquired in a transaction under the Exemptive Order unless the disposition is done on a pro rata basis. Pursuant to the Exemptive Order, the Board will oversee our participation in the co-investment program. As required by the Exemptive Order, we have adopted, and the Board has approved, policies and procedures reasonably designed to ensure compliance with the terms of the Exemptive Order, and the Investment Adviser and our Chief Compliance Officer will provide reporting to the Board.

On June 23, 2023, we entered into the Uncommitted Revolving Loan Agreement with NMF Investments III, L.L.C., an affiliate of the Investment Adviser, with a $10.0 million maximum amount of borrowings available under the Unsecured Management Company Revolver, which has a maturity date of December 31, 2025. See Item 1.—Financial Statements—Note 6. Borrowings in this Quarterly Report on Form 10-Q for more information.

73

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

We are subject to certain financial market risks, such as interest rate fluctuations. Because we fund a portion of our investments with borrowings, our net investment income is affected by the difference between the rate at which we invest and the rate at which we borrow. As a result, there can be no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income. The Federal Reserve held interest rates steady in the first and second quarters of 2025, following consecutive rate reductions in the third and fourth quarter of 2024. The Federal Reserve has indicated it will consider additional rate reductions in the near term; however, future reductions to benchmark rates are not certain. In a high interest rate environment, our net investment income would increase due to an increase in interest income generated by our investment portfolio. However, our cost of funds would also increase, which would also impact net investment income. It is possible that the Federal Reserve's tightening cycle could result in a recession in the United States, which would likely decrease interest rates. Alternatively, in a prolonged low interest rate environment, including a reduction of base rates, such as SOFR to zero, the difference between the total interest income earned on interest earning assets and the total interest expense incurred on interest bearing liabilities may be compressed, reducing our net interest income and potentially adversely affecting our operating results. During the six months ended June 30, 2025, certain of the loans held in our portfolio had floating Prime or SOFR interest rates. As of June 30, 2025, approximately 98.5% of our investments at fair value (excluding unfunded debt investments) represent floating-rate investments with a SOFR floor (includes investments bearing prime interest rate contracts) and approximately 1.5% of our investments at fair value represent fixed-rate investments. Additionally, our BMO Subscription Line is also subject to floating interest rates and is currently paid based on floating SOFR rates and prime interest rates.

The following table estimates the potential changes in interest income net of interest expense, should interest rates decrease by 200, 150, 100 or 50 basis points, or increase by 50, 100, 150 or 200 basis points. Interest income is calculated as revenue from interest generated from our portfolio of investments held on June 30, 2025. Interest expense is calculated based on the terms of our outstanding Unsecured Management Company Revolver and BMO Subscription Line. For our Unsecured Management Company Revolver and BMO Subscription Line, we use the outstanding balance as of June 30, 2025. This analysis does not take into account the impact of the incentive fee or other expenses. These hypothetical calculations are based on a model of the investments in our portfolio, held as of June 30, 2025, and are only adjusted for assumed changes in the underlying base interest rates.

Actual results could differ significantly from those estimated in the table.

Change in Interest Rates	Estimated Percentage Change in Interest Income Net of Interest Expense (unaudited)
-200 Basis Points	(20.04)	%
-150 Basis Points	(15.03)	%
-100 Basis Points	(10.02)	%
-50 Basis Points	(5.01)	%
+50 Basis Points	5.01	%
+100 Basis Points	10.02	%
+150 Basis Points	15.03	%
+200 Basis Points	20.04	%

Item 4.    Controls and Procedures

(a)Evaluation of Disclosure Controls and Procedures

As of June 30, 2025 (the end of the period covered by this report), we, including our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended). Based on that evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective and provided reasonable assurance that information required to be disclosed in our periodic SEC filings is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. However, in evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of such possible controls and procedures.

(b)Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

From time to time, we may be a party to certain legal proceedings incidental to the normal course of our business including the enforcement of our rights under contracts with our portfolio companies. While the outcome of these legal proceedings cannot be predicted with certainty, we do not expect that these proceedings will have a material effect upon our business, financial condition or results of operations.
