PRELIMINARY PROSPECTUS SUPPLEMENT

(to Prospectus dated June 26, 2024)

New Mountain Finance Corporation

% Notes due

New Mountain Finance Corporation (“NMFC”, the “Company”, “we”, “us” and “our”) is a Delaware corporation that was originally incorporated on June 29, 2010. 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”). 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.

We are offering $ in aggregate principal amount of % notes due , which we refer to as the “Notes.” The Notes will mature on , . We will pay interest on the Notes on and of each year, beginning on , . We may redeem the Notes in whole or in part at any time or from time to time at the redemption price discussed under the caption “Description of Notes — Optional Redemption” in this prospectus supplement. In addition, holders of the Notes can require us to repurchase the Notes at 100% of their principal amount upon the occurrence of a Change of Control Repurchase Event (as defined herein). The Notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The Notes will be our direct, general unsecured obligations and rank pari passu, or equal, with all existing and future unsecured unsubordinated indebtedness issued by us, including, as of September 18, 2024, our $200 million principal amount of 3.875% fixed-rate notes due 2026 (the “2021A Unsecured Notes”), our $75 million principal amount of 5.900% fixed-rate notes due 2027 (the “2022A Unsecured Notes”), our $115 million principal amount of 8.250% fixed-rate notes due 2028 (the “8.250% Unsecured Notes”), our $300 million principal amount of 6.875% fixed-rate notes due 2029 (the “6.875% Unsecured Notes”) and together with the 2021A Unsecured Notes, the 2022A Unsecured Notes, and the 8.250% Unsecured Notes, the “Unsecured Notes”), and our $260 million principal amount of 7.50% fixed-rate unsecured convertible notes due 2025 (the “2022 Convertible Notes”). Because the Notes will not be secured by any of our assets, they will be effectively subordinated, or junior, to any of our secured indebtedness or other obligations (including unsecured indebtedness that we later secure), to the extent of the value of the assets securing such indebtedness, including, without limitation, borrowings under our Third Amended and Restated Loan and Security Agreement with Wells Fargo Bank, National Association, of which we had $400.2 million outstanding as of September 18, 2024 (the “Holdings Credit Facility”), borrowings under our Amended and Restated Senior Secured Revolving Credit Agreement with Goldman Sachs Bank USA, Morgan Stanley Bank, N.A., Stifel Bank & Trust and MUFG Union Bank, N.A., of which we had $144.0 million, which included £26.7 million denominated in GBP and €17.4 million denominated in EUR that has been converted to U.S. dollars, outstanding as of September 18, 2024 (the “NMFC Credit Facility”), borrowings under our Revolving Loan Agreement with NMF Investments III, L.L.C., of which we had $0 outstanding as of September 18, 2024 (the “Unsecured Management Company Revolver”), borrowings under our Loan Financing and Servicing Agreement with Deutsche Bank AG, New York Branch, of which we had $182.0 million outstanding as of September 18, 2024 (the “DB Credit Facility”), and borrowings under our Revolving Credit Agreement with City National Bank, of which we had $0.2 million outstanding as of September 18, 2024 (the “NMNLC Credit Facility II” and together with the Holdings Credit Facility, the NMFC Credit Facility, the Unsecured Management Company Revolver, and the DB Credit Facility, the “Credit Facilities”). The Notes will be structurally subordinated, or junior, to all existing and future indebtedness and other obligations (including trade payables) incurred by our subsidiaries, financing vehicles or similar facilities, including the $300.0 million in SBA-guaranteed debentures outstanding as of September 18, 2024, because the Notes are obligations exclusively of NMFC and not of any of our subsidiaries. None of our subsidiaries are a guarantor of the Notes and the Notes will not be required to be guaranteed by any subsidiary we may acquire or create in the future. In any liquidation, dissolution, bankruptcy or other similar proceeding, the holders of any of our existing or future secured indebtedness may assert rights against the assets pledged to secure that indebtedness in order to receive full payment of their indebtedness before the assets may be used to pay other creditors, including the holders of the Notes, and any assets of our subsidiaries will not be directly available to satisfy the claims of our creditors, including holders of the Notes. For further information, see the section titled “Description of Notes” in this prospectus supplement.

The investments that we invest in are 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 our net asset value (“NAV”) and income distributions. Our investments are also primarily floating rate debt investments that contain interest reset provisions that may make it more difficult for borrowers to make debt repayments to us if interest rates rise. In addition, some of our 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. Our debt investments may also lose significant market value before a default occurs. Furthermore, an active trading market may not exist for these securities. This illiquidity may make it more difficult to value our investments.

Investing in the Notes involves risks, including the risk of leverage, that are described in the “Supplementary Risk Factors” section beginning on page S-13 of this prospectus supplement and the “Risk Factors” section beginning on page 18 of the accompanying prospectus and in Part I, Item 1A of our most recent Annual Report on Form 10-K, in Part II, Item 1A of our Quarterly Reports on Form 10-Q, and under similar headings in the other documents that are filed after the date hereof an incorporated by reference in this prospectus supplement and the accompanying prospectus.

Overview

We are a Delaware corporation that was originally incorporated on June 29, 2010 and completed our initial public offering (“IPO”) on May 19, 2011. 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, 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”). Since our IPO, and through June 30, 2024, we have raised approximately $1,034.6 million in net proceeds from additional offerings of common stock.

The Investment Adviser is a wholly owned subsidiary of 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 approximately $55 billion of assets under management as of June 30, 2024, 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. The Administrator provides the administrative services necessary to conduct our day-to-day operations.

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. 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

S-3

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.

We make investments through both primary originations and open-market secondary purchases. We primarily target loans to, and invest in, U.S. middle market businesses, a market segment we believe continues to be underserved by other lenders. 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. Similar to us, the investment objective of SBIC I and SBIC II is to generate current income and capital appreciation under our investment criteria. However, SBIC I and SBIC II investments must be in SBA eligible small businesses. Our portfolio may be concentrated in a limited number of industries. As of June 30, 2024, our top five industry concentrations were software, business services, healthcare, investment funds (which includes investments in our joint ventures) and consumer services.

As of June 30, 2024, our NAV was approximately $1,374.1 million and our portfolio had a fair value of approximately $3,213.8 million in 122 portfolio companies. At June 30, 2024 and December 31, 2023 our weighted average yield to maturity at cost for income producing investments (“YTM at Cost”) was approximately 11.1% and 10.9% respectively. This YTM at Cost calculation assumes that all investments, including secured collateralized agreements, not on non-accrual are purchased at cost on the quarter end date and held until their respective maturities with no prepayments or losses and exited at par at maturity.

At June 30, 2024 and December 31, 2023, our weighted average yield to maturity at cost for all investments (“YTM at Cost for Investments”) was approximately 10.1% and 9.7%, respectively. This YTM at Cost for Investments calculation assumes that all investments, including secured collateralized agreements, are purchased at cost on the quarter end date and held until their respective maturities with no prepayments or losses and exited at par at maturity. YTM at Cost and YTM at Cost for Investments calculations exclude the impact of existing leverage. YTM at Cost and YTM at Cost for Investments use the London Interbank Offered Rate (“LIBOR”), Sterling Overnight Interbank Average Rate (“SONIA”), Secured Overnight Financing Rate (“SOFR”) and Euro Interbank Offered Rate (“EURIBOR”) curves at each quarter’s end date. The actual yield to maturity may be higher or lower due to the future selection of the SONIA, SOFR, and EURIBOR contracts by the individual companies in our portfolio or other factors.

The Investment Adviser

The Investment Adviser manages our day-to-day operations and provides us with investment advisory and management services. In particular, the Investment Adviser is responsible for identifying attractive investment opportunities, conducting research and due diligence on prospective investments, structuring our investments and monitoring and servicing our investments. We currently do not have, and do not intend to have, any employees. The Investment Adviser also manages other funds that may have investment mandates that are similar, in whole or in part, to ours. The Administrator provides the administrative services necessary to conduct our day-to-day operations.

S-4

As of June 30, 2024, the Investment Adviser was supported by over 250 employees and senior advisors of New Mountain Capital.

The Investment Adviser is managed by a six member investment committee (the “Investment Committee”), which is responsible for approving purchases and sales of our investments above $10.0 million in aggregate by issuer. The Investment Committee currently consists of Steven B. Klinsky, Robert A. Hamwee, John R. Kline, Adam B. Weinstein and Laura C. Holson. The sixth and final member of the Investment Committee will consist of a New Mountain Capital Managing Director who will hold the position on the Investment Committee on an annual rotating basis. Andre V. Moura served on the Investment Committee from August 2023 to July 2024. Beginning in August 2024, Robert Mulcare was appointed to the Investment Committee for a one-year term. Effective January 1, 2023, Laura C. Holson joined the Investment Committee as a new permanent member. In addition, our executive officers and certain investment professionals of the Investment Adviser are invited to all Investment Committee meetings. Purchases and dispositions below $10.0 million may be approved by our Chief Executive Officer. These approval thresholds are subject to change over time. We expect to benefit from the extensive and varied relevant experience of the investment professionals serving on the Investment Committee, which includes expertise in private equity, primary and secondary leveraged credit, private mezzanine finance and distressed debt.

Competitive Advantages

We believe that we have the following competitive advantages over other capital providers to middle market companies:

Proven and Differentiated Investment Style With Areas of Deep Industry Knowledge

In making its investment decisions, the Investment Adviser applies New Mountain Capital’s long-standing, consistent investment approach that has been in place since its founding in 1999. We focus on companies in defensive growth niches of the middle market space where we believe few debt funds have built equivalent research and operational size and scale.

We benefit directly from New Mountain Capital’s private equity investment strategy that seeks to identify attractive investment sectors from the top down and then works to become a well-positioned investor in these sectors. New Mountain Capital focuses on companies and industries with sustainable strengths in all economic cycles, particularly ones that are defensive in nature, that have secular tailwinds and can maintain pricing power in the midst of a recessionary and/or inflationary environment. New Mountain Capital focuses on companies within sectors in which it has significant expertise (examples include software, education, niche healthcare, business services, consumer services and distribution & logistics) while typically avoiding investments in companies with products or services that serve markets that are highly cyclical, have the potential for long-term decline, are overly-dependent on consumer demand or are commodity-like in nature.

In making its investment decisions, the Investment Adviser has adopted the approach of New Mountain Capital, which is based on three primary investment principles:

A.A generalist approach, combined with proactive pursuit of the highest quality opportunities within carefully selected industries, identified via an intensive and structured ongoing research process;

B.Emphasis on strong downside protection and strict risk controls; and

C.Continued search for superior risk adjusted returns, combined with timely, intelligent exits and outstanding return performance.

Experienced Management Team and Established Platform

S-5

directors and Senior Advisor of New Mountain Capital, was formerly President of GSC Group, Inc. (“GSC”), where he was the portfolio manager of GSC’s distressed debt funds and led the development of GSC’s CLOs. John R. Kline, our President and Chief Executive Officer and Managing Director of New Mountain Capital, worked at GSC as an investment analyst and trader for GSC’s control distressed and corporate credit funds and at Goldman, Sachs & Co. LLC in the Credit Risk Management and Advisory Group. Laura C. Holson, our Chief Operating Officer and Managing Director of New Mountain Capital, joined New Mountain in 2009 as a private equity investment professional and focused on the credit business starting in 2011. She also served as Head of Capital Markets from 2017 to 2021, where she managed the Firm’s financing activities and relationships across its various product lines.

Many of the debt investments that we have made to date have been in the same companies with which New Mountain Capital has already conducted months of intensive acquisition due diligence related to potential private equity investments. We believe that private equity underwriting due diligence is usually more robust than typical due diligence for loan underwriting. In its underwriting of debt investments, the Investment Adviser is able to utilize the research and hands-on operating experience that New Mountain Capital’s private equity underwriting teams possess regarding the individual companies and industries. Business and industry due diligence is led by a team of investment professionals of the Investment Adviser that generally consists of three to seven individuals, typically based on their relevant company and/or industry specific knowledge. Additionally, the Investment Adviser is also able to utilize its relationships with operating management teams and other private equity sponsors. We believe this differentiates us from many of our competitors.

Significant Sourcing Capabilities and Relationships

We believe the Investment Adviser’s ability to source attractive investment opportunities is greatly aided by both New Mountain Capital’s historical and current reviews of private equity opportunities in the business segments we target. To date, a majority of the investments that we have made are in the debt of companies and industry sectors that were first identified and reviewed in connection with New Mountain Capital’s private equity efforts, and the majority of our current pipeline reflects this as well. Furthermore, the Investment Adviser’s investment professionals have deep and longstanding relationships in both the private equity sponsor community and the lending/agency community which they have and will continue to utilize to generate investment opportunities.

Risk Management through Various Cycles

New Mountain Capital has emphasized tight control of risk since its inception. To date, New Mountain Capital has never experienced a bankruptcy of any of its portfolio companies in its private equity efforts. The Investment Adviser seeks to emphasize tight control of risk with our investments in several important ways, consistent with New Mountain Capital’s historical approach. In particular, the Investment Adviser:

•Emphasizes the origination or purchase of debt in what the Investment Adviser believes are defensive growth companies, which are less likely to be dependent on macro-economic cycles;

•Targets investments in companies that are preeminent market leaders in their own industries, and when possible, investments in companies that have strong management teams whose skills are difficult for competitors to acquire or reproduce; and

•Targets investments in companies with significant equity value in excess of our debt investments.

Access to Non Mark to Market, Seasoned Leverage Facilities

The amount available under the Holdings Credit Facility and DB Credit Facility are generally not subject to reduction as a result of mark to market fluctuations in our portfolio investments. For a detailed discussion of our credit facilities, see “Item 1 — Financial Statements — Note 7. Borrowings” in our most recent Quarterly Report on Form 10-Q.

S-6

Market Opportunity

We believe that the size of the market for investments that we target, coupled with the demands of middle market companies for flexible sources of capital at competitive terms and rates, create an attractive investment environment for us.

•Large pool of uninvested private equity capital available for new buyouts. We expect that private equity firms will continue to pursue acquisitions and will seek to leverage their equity investments with mezzanine loans and/or senior loans (including traditional first and second lien, as well as unitranche loans) provided by companies such as ours.

•The leveraged finance market has a high level of financing needs over the next several years due to significant maturities. We believe that the large dollar volume of loans that need to be refinanced will present attractive opportunities to invest capital in a manner consistent with our stated objectives.

•Middle market companies continue to face difficulties in accessing the capital markets. We believe opportunities to serve the middle market will continue to exist. While many middle market companies were formerly able to raise funds by issuing high-yield bonds, we believe this approach to financing has become more difficult as institutional investors have sought to invest in larger, more liquid offerings.

•Increased regulatory scrutiny of banks has reduced middle market lending. We believe that many traditional bank lenders to middle market businesses have either exited or de-emphasized their service and product offerings in the middle market. These traditional lenders have instead focused on lending and providing other services to large corporate clients. We believe this has resulted in fewer key players and the reduced availability of debt capital to the companies we target.

•Conservative loan to value. As a result of the credit crisis, many lenders are requiring larger equity contributions from financial sponsors. Larger equity contributions create an enhanced margin of safety for lenders because leverage is a lower percentage of the implied enterprise value of the company.

•Attractive pricing. Reduced access to, and availability of, debt capital typically increases the interest rates, or pricing, of loans for middle market lenders. Recent primary debt transactions in this market often include upfront fees, original issue discount, prepayment protections and, in some cases, warrants to purchase common stock, all of which should enhance the profitability of new loans to lenders.

Operating and Regulatory Structure

We are a closed-end, non-diversified management investment company that has elected to be regulated as a BDC under the 1940 Act and are required to maintain an asset coverage ratio, as defined in the 1940 Act, of at least 150.0% (which means we can borrow $2 for every $1 of our equity), which was reduced from 200.0% effective as of June 9, 2018 by approval of our stockholders. Changing the asset coverage ratio permits us to double our leverage, which may result in increased leverage risk and increased expenses. We include the assets and liabilities of our consolidated subsidiaries for purposes of satisfying the requirements under the 1940 Act. We received exemptive relief from the SEC on November 6, 2014, allowing us to modify the asset coverage requirement to exclude SBA-guaranteed debentures from this calculation. See “Item 1 — Business — Senior Securities” in our most recent Annual Report on Form 10-K.

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 RIC under Subchapter M of the Code. See “Certain U.S. Federal Income Tax Considerations” in the accompanying prospectus. As a RIC, we generally will not be subject to U.S. federal income tax on any net ordinary income or capital gains that we timely distribute to our stockholders as dividends if we meet certain source-of-income, distribution and asset diversification requirements. We intend to distribute to our stockholders substantially all of our annual taxable income, but we may retain certain net capital gains for reinvestment. To the extent we retain any net capital gains for reinvestment, we will be subject to U.S. federal income tax, and possibly U.S. federal excise tax, with respect to such retained amounts.

S-7

We have established the following wholly-owned direct and indirect subsidiaries:

•NMF Holdings and NMFDB, whose assets are used to secure the NMF Holdings’ credit facility and NMFDB’s credit facility, respectively;

•SBIC I and SBIC II, who have received licenses from the U.S. Small Business Administration (the “SBA”) to operate as small business investment companies (“SBICs”) under Section 301(c) of the Small Business Investment Act of 1958, as amended (the “1958 Act”) and their general partners, SBIC I GP and SBIC II GP, respectively;

•NMF Ancora Holdings, Inc., NMF QID NGL Holdings, Inc., NMF YP Holdings, Inc., NMF Permian Holdings, LLC, NMF HB, Inc., NMF TRM, LLC, NMF Pioneer, Inc. and NMF OEC, Inc., which are treated as corporations for U.S. federal income tax purposes and are intended to facilitate our compliance with the requirements to be treated as a RIC under the Code by holding equity or equity-like investments in portfolio companies organized as limited liability companies (or other forms of pass-through entities); we consolidate our tax blocker corporations for accounting purposes, but the tax blocker corporations are not consolidated for U.S. federal income tax purposes and may incur income tax expense as a result of their ownership of the portfolio companies; and

•New Mountain Finance Servicing, L.L.C., which serves as the administrative agent on certain investment transactions.

NMNLC is a majority-owned consolidated subsidiary of ours, which acquires commercial real estate properties that are subject to “triple net” leases, and has elected to be treated, and intends to comply with the requirements to continue to qualify annually, as a real estate investment trust, or REIT, within the meaning of Section 856(a) of the Code.

Risk Factors

An investment in the Notes involves risk, including the risk of leverage and the risk that our operating policies and strategies may change without prior notice to holders of our securities. These and other risks are described in the section titled “Supplementary Risk Factors” in this prospectus supplement, “Risk Factors” in the accompanying prospectus and in any free writing prospectuses we have authorized for use in connection with this offering, and under similar headings in the documents that are incorporated by reference into this prospectus supplement and the accompanying prospectus, including the section titled “Risk Factors” included in our most recent Annual Report on Form 10-K, the section titled “Risk Factors” in our most recent Quarterly Report on Form 10-Q, as well as in any of our subsequent SEC filings.

See “Capitalization.”

Denominations			We will issue the Notes in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Optional Redemption			We may redeem some or all of the Notes, in whole or in part, at any time, or from time to time, at a redemption price equal to the greater of (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus basis points less (b) interest accrued to the date of redemption, and (2) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to the redemption date. Any exercise of our option to redeem the Notes will be done in compliance with the 1940 Act.

Sinking Fund			The Notes will not be subject to any sinking fund. A sinking fund is a reserve fund accumulated over a period of time for the retirement of debt.

Offer to Purchase Upon a Change of Control Repurchase Event			If a Change of Control Repurchase Event occurs prior to maturity, unless we have exercised our right to redeem the Notes in full, holders will have the right, at their option, to require us to repurchase for cash some or all of the Notes at a repurchase price equal to 100% of the principal amount of the Notes being repurchased, plus accrued and unpaid interest to, but not including, the repurchase date.

Legal Defeasance			The Notes are subject to legal defeasance by us, which means that, subject to the satisfaction of certain conditions, including, but not limited to, (i) depositing in trust for the benefit of the holders of the Notes a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the Notes on their various due dates and (ii) delivering to the trustee an opinion of counsel as described herein under “Description of Notes — Satisfaction and Discharge; Defeasance,” we can legally release ourselves from all payment and other obligations on the Notes.

S-10


Covenant Defeasance			The Notes are subject to covenant defeasance by us, which means that, subject to the satisfaction of certain conditions, including, but not limited to, (i) depositing in trust for the benefit of the holders of the Notes a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the Notes on their various due dates and (ii) delivering to the trustee an opinion of counsel as described herein under “Description of Notes — Satisfaction and Discharge; Defeasance,” we will be released from some of the restrictive covenants in the indenture.

Form of Notes			The Notes will be represented by global securities that will be deposited and registered in the name of The Depository Trust Company, or DTC, or its nominee. This means that, except in limited circumstances, you will not receive certificates for the Notes. Beneficial interests in the Notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the Notes through either DTC, if they are a participant, or indirectly through organizations that are participants in DTC.

Trustee, Paying Agent and Registrar			U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association).

Events of Default			If an event of default (as described under “Description of Notes”) on the Notes occurs, the principal amount of the Notes, plus accrued and unpaid interest, may be declared immediately due and payable, subject to conditions set forth in the indenture. These amounts automatically become due and payable in the case of certain types of bankruptcy or insolvency events involving us.

Other Covenants			In addition to the covenants described in the accompanying prospectus, the following covenants shall apply to the Notes: •We agree that for the period of time during which the Notes are outstanding, we will not violate, whether or not we are subject thereto, Section 18(a)(1)(A) as modified by Section 61(a) of the 1940 Act or any successor provisions, but giving effect, in either case, to any exemptive relief granted to us by the SEC. •If, at any time, we are not subject to the reporting requirements of Sections 13 or 15(d) of the Exchange Act to file any periodic reports with the SEC, we agree to furnish to holders of the Notes and the trustee, for the period of time during which the Notes are outstanding, our audited annual consolidated financial statements, within 90 days of our fiscal year end, and unaudited interim consolidated financial statements, within 45 days of our fiscal quarter end (other than our fourth fiscal quarter). All such financial statements will be prepared, in all material respects, in accordance with applicable United States generally accepted accounting principles, or GAAP.

S-11


No Established Trading Market			The Notes are a new issue of securities with no established trading market. The Notes will not be listed on any securities exchange or quoted on any automated dealer quotation system. Although certain of the underwriters have informed us that they currently intend to make a market in the Notes, as permitted by applicable laws and regulations, they are not obligated to do so and may discontinue any such market making activities at any time without notice. See “Underwriting.” Accordingly, we cannot assure you that a liquid market for the Notes will develop or be maintained.

Global Clearance and Settlement Procedures			Interests in the Notes will trade in DTC’s Same Day Funds Settlement System, and any permitted secondary market trading activity in such Notes will, therefore, be required by DTC to be settled in immediately available funds. None of the Company, the trustee or the paying agent will have any responsibility or liability for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Use of Proceeds			We estimate that the net proceeds we receive from the sale of the Notes will be approximately $ , based on a public offering price of % of par, after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We expect to use the net proceeds from this offering to repay existing indebtedness under the Holdings Credit Facility, the NMFC Credit Facility, and the DB Credit Facility.

Governing Law			The Notes and the indenture are governed by and construed in accordance with the laws of the State of New York.

SUPPLEMENTARY RISK FACTORS

Investing in the Notes involves a number of significant risks. In addition to the other information contained in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference, you should carefully consider the risk factors set forth below, the risk factors incorporated by reference in the accompanying prospectus and as described in the section titled “Risk Factors” in our most recent Annual Report on Form 10-K, the section titled “Risk Factors” in our most recent Quarterly Report on Form 10-Q, as well as subsequent filings with the SEC, which are incorporated by reference into this prospectus supplement and the accompanying prospectus in their entirety, before making an investment in the Notes. The risks set forth below and the risk factors incorporated by reference into this prospectus supplement and the accompanying prospectus, as described in the section titled “Risk Factors” in our most recent Annual Report on Form 10-K, the section titled “Risk Factors” in our most recent Quarterly Report on Form 10-Q, and any subsequent filings with the SEC are the principal risks with respect to the Company generally and with respect to BDCs, they may not be the only risks we face. This section nonetheless describes the principal risk factors associated with the Notes specifically. If any of the risks occur, our business, financial condition and results of operations could be materially adversely affected. In such case, our NAV and the trading price of our securities could decline and you may lose all or part of your investment. Please also read carefully the section titled “Note about Forward-Looking Statements” in this prospectus supplement and the section titled “Cautionary Statement Regarding Forward-Looking Statements” in the accompanying prospectus.

Risks Related to the Notes

The Notes will be unsecured and therefore will be effectively subordinated to any existing and future secured indebtedness, including indebtedness under our Credit Facilities.

The Notes will not be secured by any of our assets or any of the assets of any of our subsidiaries. As a result, the Notes will be effectively subordinated to any existing and future secured indebtedness we or our subsidiaries have outstanding as of the date of this prospectus supplement (including our Credit Facilities) or that we or our subsidiaries may incur in the future (or any indebtedness that is initially unsecured as to which we have granted or subsequently grant a security interest) to the extent of the value of the assets securing such indebtedness, including, without limitation, borrowings under our Credit Facilities. In any liquidation, dissolution, bankruptcy or other similar proceeding, the holders of any of our secured indebtedness or secured indebtedness of our subsidiaries may assert rights against the assets pledged to secure that indebtedness in order to receive full payment of their indebtedness before the assets may be used to pay other creditors, including the holders of the Notes. As of September 18, 2024, we had $400.2 million outstanding under the Holdings Credit Facility, $144.0 million, which included £26.7 million denominated in GBP and €17.4 million denominated in EUR that has been converted to U.S. dollars outstanding under the NMFC Credit Facility, $0 outstanding under the Unsecured Management Company Revolver, $182.0 million outstanding under the DB Credit Facility, and $0.2 million outstanding under the NMNLC Credit Facility II.

The Notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries.

The Notes will be obligations exclusively of New Mountain Finance Corporation, and not of any of our subsidiaries. None of our subsidiaries will be a guarantor of the Notes, and the Notes will not be required to be guaranteed by any subsidiary we may acquire or create in the future. Any assets of our subsidiaries will not be directly available to satisfy the claims of our creditors, including holders of the Notes. Except to the extent we are a creditor with recognized claims against our subsidiaries, all claims of creditors of our subsidiaries will have priority over our equity interests in such entities (and therefore the claims of our creditors, including holders of the Notes) with respect to the assets of such entities. Even if we are recognized as a creditor of one or more of these entities, our claims would still be effectively subordinated to any security interests in the assets of any such entity and to any indebtedness or other liabilities of any such entity senior to our claims. Consequently, the Notes will be structurally subordinated to all indebtedness and other liabilities of any of our existing or future subsidiaries, including the SBA-guaranteed debentures. These entities may incur substantial indebtedness in the future, all of which would be structurally senior to the Notes. As of September 18, 2024, we had $300.0 million in SBA-guaranteed debentures outstanding. The indebtedness under the SBA-guaranteed debentures are structurally senior to the Notes.

S-13

The indenture under which the Notes will be issued contains limited protection for holders of the Notes.

The indenture under which the Notes will be issued offers limited protection to holders of the Notes. The terms of the indenture and the Notes do not restrict our or any of our subsidiaries’ ability to engage in, or otherwise be a party to, a variety of corporate transactions, circumstances or events that could have a material adverse impact on your investment in the Notes. In particular, the terms of the indenture and the Notes will not place any restrictions on our or our subsidiaries’ ability to:

•issue securities or otherwise incur additional indebtedness or other obligations, including (1) any indebtedness or other obligations that would be equal in right of payment to the Notes, (2) any indebtedness or other obligations that would be secured and therefore rank effectively senior in right of payment to the Notes to the extent of the values of the assets securing such debt, (3) indebtedness of ours that is guaranteed by one or more of our subsidiaries and which therefore is structurally senior to the Notes and (4) securities, indebtedness or obligations issued or incurred by our subsidiaries that would be senior to our equity interests in those entities and therefore rank structurally senior to the Notes with respect to the assets of our subsidiaries, in each case other than an incurrence of indebtedness or other obligation that would cause a violation of Section 18(a)(1)(A) as modified by Section 61(a)(2) of the 1940 Act or any successor provisions, whether or not we continue to be subject to such provisions of the 1940 Act, but giving effect, in each case, to any exemptive relief granted to us by the SEC. Currently, these provisions generally prohibit us from incurring additional borrowings, including through the issuance of additional debt securities, unless our asset coverage, as defined in the 1940 Act, equals at least 150% after such borrowings;

•pay dividends on, or purchase or redeem or make any payments in respect of, capital stock or other securities ranking junior in right of payment to the Notes;

•sell assets (other than certain limited restrictions on our ability to consolidate, merge or sell all or substantially all of our assets);

•enter into transactions with affiliates;

•create liens (including liens on the shares of our subsidiaries) or enter into sale and leaseback transactions;

•make investments; or

•create restrictions on the payment of dividends or other amounts to us from our subsidiaries.

Furthermore, the terms of the indenture and the Notes do not protect holders of the Notes in the event that we experience changes (including significant adverse changes) in our financial condition, results of operations or credit ratings, if any, as they do not require that we or our subsidiaries adhere to any financial tests or ratios or specified levels of net worth, revenues, income, cash flow, or liquidity.

Our ability to recapitalize, incur additional debt (including additional debt that matures prior to the maturity of the Notes), and take a number of other actions that are not limited by the terms of the Notes may have important consequences for you as a holder of the Notes, including making it more difficult for us to satisfy our obligations with respect to the Notes or negatively affecting the trading value of the Notes.

Our existing indebtedness contains, and other debt we issue or incur in the future could contain, more protections for its holders than the indenture and the Notes, including additional covenants and events of default. The issuance or incurrence of any such debt with incremental protections could affect the market for, trading levels, and prices of the Notes.

There is no existing trading market for the Notes, and an active trading market for the Notes may not develop, which could limit your ability to sell the Notes and/or the market price of the Notes.

The Notes will be a new issue of debt securities for which there is currently no trading market. We do not intend to apply for listing of the Notes on any securities exchange or for quotation of the Notes on any automated dealer

S-14

quotation system. We cannot provide any assurances that an active trading market will develop or be maintained for the Notes or that you will be able to sell your Notes. If the Notes are traded after their initial issuance, they may trade at a discount to their initial offering price depending on prevailing interest rates, the market for similar securities, our credit ratings, if any, general economic conditions, our financial condition, performance and prospects and other factors. Certain of the underwriters have advised us that they intend to make a market in the Notes, but they are not obligated to do so. Any market-making activity will be subject to limits imposed by law, general economic conditions, or other relevant factors. The underwriters may discontinue any market-making in the Notes at any time at their sole discretion.

Accordingly, we cannot assure you that a liquid trading market will develop or be maintained for the Notes, that you will be able to sell your Notes at a particular time or that the price you receive when you sell will be favorable. To the extent an active trading market does not develop, the liquidity and trading price for the Notes may be adversely affected. Accordingly, you may be required to bear the financial risk of an investment in the Notes for an indefinite period of time.

We may choose to redeem the Notes when prevailing interest rates are relatively low, which may adversely affect your return on the Notes.

The Notes are redeemable in whole or in part upon certain conditions at any time or from time to time at our option. We may choose to redeem the Notes from time to time, especially when prevailing interest rates are lower than the rate borne by the Notes. If prevailing rates are lower at the time of redemption, you would not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate on the Notes being redeemed. Our redemption right also may adversely impact your ability to sell the Notes as the optional redemption date or period approaches.

We may not be able to repurchase the Notes upon a Change of Control Repurchase Event.

Upon the occurrence of a Change of Control Repurchase Event, as defined in the indenture that governs the Notes, as supplemented, subject to certain conditions, we will be required to offer to repurchase some or all of the outstanding Notes at 100% of their principal amount, plus accrued and unpaid interest. The source of funds for that purchase of Notes will be our available cash or cash generated from our operations or other potential sources, including borrowings, investment repayments, sales of assets or sales of equity. We cannot assure you that sufficient funds from such sources will be available at the time of any Change of Control Repurchase Event to make required repurchases of Notes tendered.

The terms of certain of our Credit Facilities provide that certain change of control events will constitute an event of default, thereunder entitling the lenders to accelerate any indebtedness outstanding under the credit facility at that time and to terminate the credit facility. In addition, the documents governing our Unsecured Notes (with the exception of the 8.250% Unsecured Notes) and 2022 Convertible Notes each contain a provision that would require us to offer to purchase the respective Unsecured Notes or 2022 Convertible Notes upon the occurrence of a fundamental change, such as a change in control.

Any failure to comply with these provisions would constitute an event of default under each of the other agreements governing our indebtedness, including the indenture. Our future debt instruments also may contain similar restrictions and provisions. If the holders of the Notes exercise their right to require us to repurchase all the Notes upon a Change of Control Repurchase Event, the financial effect of this repurchase could cause a default under our future debt instruments, even if the Change of Control Repurchase Event itself would not cause a default. It is possible that we will not have sufficient funds at the time of the Change of Control Repurchase Event to make the required repurchase of the Notes or our other debt. See “Description of Notes—Offer to Repurchase Upon a Change of Control Repurchase Event” in this prospectus supplement for more information.

The amount of our debt outstanding will increase as a result of this offering, and if we default on our obligations to pay our other indebtedness, we may not be able to make payments on the Notes.

Any default under the agreements governing our indebtedness, including a default under the Credit Facilities, the indentures governing the Unsecured Notes and the 2022 Convertible Notes, or other indebtedness to which we

S-15

may be a party, that is not waived by the required lenders or the holders, and the remedies sought by the lenders or the holders of such indebtedness could make us unable to pay principal, premium, if any, and interest on the Notes and substantially decrease the market value of the Notes. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, and interest on our indebtedness, or if we otherwise fail to comply with the various covenants, including financial and operating covenants, as applicable, in the instruments governing our indebtedness, we could be in default under the terms of the agreements governing such indebtedness (including the Credit Facilities, the Unsecured Notes, and the 2022 Convertible Notes). In the event of such default, the holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest, the lenders under the Credit Facilities or other debt we may incur in the future could elect to terminate their commitment, cease making further loans and institute foreclosure proceedings against our assets, and we could be forced into bankruptcy or liquidation. In addition, any such default may constitute a default under the Notes, which could further limit our ability to repay our debt, including the Notes.

Our ability to generate sufficient cash flow in the future is, to some extent, subject to general economic, financial, competitive, legislative and regulatory factors as well as other factors that are beyond our control. We cannot assure you that our business will generate cash flow from operations, or that future borrowings will be available to us under the Credit Facilities or otherwise, in an amount sufficient to enable us to meet our payment obligations under the Notes, the Unsecured Notes, the 2022 Convertible Notes, and the Credit Facilities, and to fund other liquidity needs.

If our operating performance declines and we are not able to generate sufficient cash flow to service our debt obligations, we may, in the future, need to refinance or restructure our debt, including any Notes sold, sell assets, reduce or delay capital investments, seek to raise additional capital or seek to obtain waivers from the required lenders under the Credit Facilities, the holders of the Unsecured Notes, the 2022 Convertible Notes, or other debt that we may incur in the future to avoid being in default. If we are unable to implement one or more of these alternatives, we may not be able to meet our payment obligations under the Notes and our other debt. If we breach our covenants under the Credit Facilities, the Unsecured Notes, the 2022 Convertible Notes, or our other debt and seek a waiver, we may not be able to obtain a waiver from the required lenders or the holders thereof. If this occurs, we would be in default under the Credit Facilities, the Unsecured Notes, the 2022 Convertible Notes, or other debt, the lenders or holders could exercise their rights as described above, and we could be forced into bankruptcy or liquidation. If we are unable to repay debt, lenders having secured obligations could proceed against the collateral securing the debt.

A downgrade, suspension or withdrawal of the credit rating assigned by a rating agency to us or the Notes or changes in the debt markets could cause the liquidity or market value of the Notes to decline significantly.

Our credit ratings are an assessment by rating agencies of our ability to pay our debts when due. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the Notes. These credit ratings may not reflect the potential impact of risks relating to the structure or marketing of the Notes. Credit ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization in its sole discretion. Neither we nor any underwriter undertakes any obligation to maintain our credit ratings or to advise holders of Notes of any changes in our credit ratings. There can be no assurance that our credit ratings will remain for any given period of time or that such credit ratings will not be lowered or withdrawn entirely by the rating agencies if in their judgment future circumstances relating to the basis of the credit ratings, such as adverse changes in the Company, so warrant. The conditions of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, which could have an adverse effect on the market prices of the Notes.

We employ leverage, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing in us.

Borrowings, also known as leverage, magnify the potential for gain or loss on amounts invested and, therefore, increase the risks associated with investing in us. We borrow from and issue senior debt securities to banks and other lenders that is secured by a lien on our assets. Holders of these senior securities have fixed dollar claims on our

S-16

assets that are superior to the claims of the holders of our securities. Leverage is generally considered a speculative investment technique. Any increase in our income in excess of interest payable on our outstanding indebtedness would cause our net income to increase more than it would have had we not incurred leverage, while any decrease in our income would cause net income to decline more sharply than it would have had we not incurred leverage. Such a decline could negatively affect our ability to make common stock distributions or scheduled debt payments, including with respect to the Notes, as defined below. There can be no assurance that our leveraging strategy will be successful.

Our outstanding indebtedness imposes, and additional debt we may incur in the future will likely impose, financial and operating covenants that restrict our business activities, including limitations that could hinder our ability to finance additional loans and investments or to make the distributions required to maintain our RIC tax treatment. A failure to add new debt facilities or issue additional debt securities or other evidences of indebtedness in lieu of or in addition to existing indebtedness could have a material adverse effect on our business, financial condition or results of operations.

As of September 18, 2024, we had $400.2 million outstanding under the Holdings Credit Facility, $144.0 million, which included £26.7 million denominated in GBP and €17.4 million denominated in EUR that has been converted to U.S. dollars, outstanding under the NMFC Credit Facility, $0 outstanding under the Unsecured Management Company Revolver, $182.0 million outstanding under the DB Credit Facility, and $0.2 million outstanding under the NMNLC Credit Facility II, $300.0 million in SBA-guaranteed debentures outstanding, $690.0 million in aggregate principal amount outstanding of the Unsecured Notes, and $260.0 million in aggregate principal amount outstanding of the 2022 Convertible Notes. We may incur additional indebtedness in the future, including, but not limited to, borrowings under the Credit Facilities or the issuance of additional debt securities in one or more public or private offerings, although there can be no assurance that we will be successful in doing so. Our ability to service our debt depends largely on our financial performance and is subject to prevailing economic conditions and competitive pressures. The amount of leverage that we employ at any particular time will depend on our management’s and our board of directors’ assessment of market and other factors at the time of any proposed borrowing.

As a BDC, we are generally required to meet a coverage ratio at least equal to 150% of total assets to total borrowings and other senior securities, which include all of our borrowings (other than the SBIC Subsidiaries’ SBA-guaranteed debentures under the terms of SEC exemptive relief) and any preferred stock we may issue in the future. If this ratio declines below 150%, we may not be able to incur additional debt and may need to sell a portion of our investments to repay some debt when it is disadvantageous to do so, and we may not be able to make distributions to our stockholders. Additionally, because the SBA-guaranteed debentures are excluded from the calculation of our asset ratio coverage for purpose of compliance with the 1940 Act under the terms of our SEC exemptive relief, we may have a ratio of total assets to borrowings (including the SBA-guaranteed debentures) greater than 150% and our asset coverage ratio may not fully reflect the risks relating to our outstanding debt and capitalization. For example, our asset coverage ratio as of June 30, 2024 was 182.8%. However, including SBA-guaranteed debentures, our total assets to total borrowings would be 170.1% as of June 30, 2024.

We are exposed to risks associated with the elevated interest rate environment.

Because we borrow to fund our investments (such as the issuance of the Notes), a portion of our net investment income may be dependent upon the difference between the interest rate at which we borrow funds and the interest rate at which we invest these funds. As a result, we can offer no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income.

In response to recent market indicators showing a rise in inflation, the Federal Reserve has raised certain benchmark interest rates in an effort to slow inflation. This elevated interest rate environment may impact our cost of capital and net investment income. Since March 2022, the Federal Reserve has been raising interest rates. While the Federal Reserve cut its benchmark rate in the third quarter of 2024 for the first time since March 2020 and indicated that there may be additional rate cuts in 2024, 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 could also impact net

S-17

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 SONIA or 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.

We may hedge against such interest rate fluctuations by using standard hedging instruments such as futures, options, swaps, and forward contracts, subject to applicable legal requirements, including without limitation, all necessary registrations (or exemptions from registration) with the Commodity Futures Trading Commission. These activities may limit our ability to participate in the benefits of lower interest rates with respect to the hedged borrowings. Adverse developments resulting from changes in interest rates or hedging transactions could have a material adverse effect on our business, financial condition and results of operations.

General interest rate fluctuations may have a substantial negative impact on our investments and investment opportunities and, accordingly, may have a material adverse effect on our ability to achieve our investment objective and the rate of return on invested capital. 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.

DESCRIPTION OF NOTES

The following description of the particular terms of the Notes supplements and, to the extent inconsistent therewith, replaces the description of the general terms and provisions of the debt securities set forth in the accompanying prospectus.

We will issue the Notes under a base indenture and sixth supplemental indenture thereto (the “sixth supplemental indenture”), to be entered into between us and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee (the “trustee”). As used in this section, all references to the indenture mean the base indenture as supplemented by the sixth supplemental indenture. The terms of the Notes include those expressly set forth in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended, or the TIA.

The following description is a summary of the material provisions of the Notes and the indenture and does not purport to be complete. This summary is subject to and is qualified by reference to all the provisions of the Notes and the indenture, including the definitions of certain terms used in the indenture. We urge you to read these documents because they, and not this description, define your rights as a holder of the Notes.

For purposes of this description, references to “we,” “our,” “us” and “NMFC” refer only to New Mountain Finance Corporation and not to any of its current or future subsidiaries and references to “subsidiaries” refer only to our consolidated subsidiaries and exclude any investments held by New Mountain Finance Corporation in the ordinary course of business which are not, under GAAP, consolidated on the financial statements of New Mountain Finance Corporation and its subsidiaries.

General

The Notes:

•will be our direct, general unsecured, senior obligations;

•will be issued in an aggregate principal amount of $ million;

•will mature on , unless earlier redeemed or repurchased, as discussed below;

•will bear cash interest from , 2024 at an annual rate of % payable semi-annually on and of each year, beginning on , ;

•will be subject to redemption at our option as described under “—Optional Redemption;”

•will be subject to repurchase by us at the option of the holders following a Change of Control Repurchase Event (as defined below under “—Offer to Repurchase Upon a Change of Control Repurchase Event”), at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the date of repurchase;

•will be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof; and

•will be represented by one or more registered Notes in global form, but in certain limited circumstances may be represented by Notes in definitive form. See “—Book-Entry, Settlement and Clearance.”

The indenture does not limit the amount of debt that may be issued by us or our subsidiaries under the indenture or otherwise. The indenture does not contain any financial covenants and does not restrict us from paying dividends or issuing or repurchasing our other securities. Other than restrictions described under “—Offer to Repurchase Upon a Change of Control Repurchase Event” and “—Merger, Consolidation or Sale of Assets” below, the indenture does not contain any covenants or other provisions designed to afford holders of the Notes protection in the event of a highly leveraged transaction involving us or in the event of a decline in our credit rating as the result of a takeover, recapitalization, highly leveraged transaction or similar restructuring involving us that could adversely affect such holders.

S-22

We may, without the consent of the holders, issue further additional Notes under the indenture with the same terms (except for the issue date, public offering price and, if applicable, the initial interest payment date) and with the same CUSIP numbers as the Notes in an unlimited aggregate principal amount; provided that such additional Notes must either be issued in a “qualified reopening” for U.S. federal income tax purposes or otherwise be part of the same issue as the Notes offered hereby for U.S. federal income tax purposes if such additional Notes will have the same CUSIP numbers as the Notes.

We do not intend to list the Notes on any securities exchange or any automated dealer quotation system.

Payments on the Notes; Paying Agent and Registrar; Transfer and Exchange

We will pay the principal of, and interest on, the Notes in global form registered in the name of or held by DTC or its nominee in immediately available funds to DTC or its nominee, as the case may be, as the registered holder of such Global Note (as defined below).

Payment of principal of (and premium, if any) and any such interest on the Notes will be made at the corporate trust office of the paying agent, which initially shall be the trustee in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that, in the case of notes that are not in global form, at our option payment of interest may be made by check mailed to the address of the person entitled thereto as such address shall appear in the security register.

A holder of Notes may transfer or exchange Notes at the office of the registrar in accordance with the indenture. A holder may be required, among other things, to furnish appropriate endorsements and transfer documents. No service charge will be imposed by us, the trustee or the registrar for any registration of transfer or exchange of Notes, but we or the trustee may require a holder to pay a sum sufficient to cover any transfer tax or other similar governmental charge required by law or permitted by the indenture. The transferor of any Note shall provide or cause to be provided to the trustee, upon reasonable request therefore, all information necessary to allow the trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Internal Revenue Code Section 6045. The trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

The registered holder of a Note will be treated as its owner for all purposes.

Interest

The Notes bear cash interest at a rate of % per year until maturity. Interest on the Notes will accrue from , 2024 or from the most recent date on which interest has been paid or duly provided for. Interest is payable semiannually in arrears on and of each year, beginning on , .

Interest will be paid to the person in whose name a Note is registered at 5:00 p.m. New York City time (the “close of business”) on or (whether or not a business day), as the case may be, immediately preceding the relevant interest payment date. Interest on the Notes will be computed on the basis of a 360-day year composed of twelve 30-day months.

If any interest payment date, redemption date, the maturity date or any earlier required repurchase date upon a Change of Control Repurchase Event (defined below) of a Note falls on a day that is not a business day, the required payment will be made on the next succeeding business day and no interest on such payment will accrue in respect of the delay. The term “business day” means, with respect to any Note, any day other than a Saturday, a Sunday or a day on which banking institutions in New York or the city in which the corporate trust office is located are authorized or obligated by law or executive order to close.

Ranking

The Notes are our direct, general unsecured obligations that rank:

•senior in right of payment to all of our future indebtedness or other obligations that are expressly subordinated, or junior, in right of payment to the Notes;

S-23

•pari passu, or equal, in right of payment with all of our existing and future indebtedness or other obligations that are not so subordinated, or junior, including, without limitation, as of September 18, 2024, $690.0 million in aggregate principal amount outstanding of the Unsecured Notes and $260.0 million in aggregate principal amount outstanding of the 2022 Convertible Notes;

•effectively subordinated, or junior, to any of our secured indebtedness or other obligations (including unsecured indebtedness that we later secure) to the extent of the value of the assets securing such indebtedness, including, without limitation, borrowings under our Holdings Credit Facility, of which we had $400.2 million outstanding as of September 18, 2024, our NMFC Credit Facility, of which we had $144.0 million, which included £26.7 million denominated in GBP and €17.4 million denominated in EUR that has been converted to U.S. dollars, outstanding as of September 18, 2024, our Unsecured Management Company Revolver, of which we had $0 outstanding as of September 18, 2024, our DB Credit Facility, of which we had $182.0 million outstanding as of September 18, 2024, and our NMNLC Credit Facility II, of which we had $0.2 million outstanding as of September 18, 2024; and

•structurally subordinated, or junior, to all existing and future indebtedness and other obligations (including trade payables) incurred by our subsidiaries, financing vehicles or similar facilities, including $300.0 million in SBA-guaranteed debentures outstanding as of September 18, 2024.

As of September 18, 2024, our total consolidated indebtedness was approximately $1,976.4 million aggregate principal amount outstanding. After giving effect to the issuance of the Notes, our total consolidated indebtedness would have been approximately $ million aggregate principal amount outstanding as of September 18, 2024. See “Capitalization.”

In the event of our bankruptcy, liquidation, reorganization or other winding up, our assets that secure secured debt will be available to pay obligations on the Notes only after all indebtedness under such secured debt has been repaid in full from such assets. We advise you that there may not be sufficient assets remaining to pay amounts due on any or all the Notes then outstanding.

Optional Redemption

Any exercise of our option to redeem the Notes will be done in compliance with the 1940 Act. We may redeem the Notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus basis points less (b) interest accrued to the date of redemption; and

(2)100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the redemption date.

“Treasury Rate” means, with respect to any redemption date, the yield determined by us in accordance with the following two paragraphs.

The Treasury Rate shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the maturity date of the Notes (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the

S-24

Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the maturity date of the Notes on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, we shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the maturity date of the Notes, as applicable. If there is no United States Treasury security maturing on the maturity date of the Notes, but there are two or more United States Treasury securities with a maturity date equally distant from the maturity date of the Notes, one with a maturity date preceding the maturity date of the Notes and one with a maturity date following the maturity date of the Notes, we shall select the United States Treasury security with a maturity date preceding the maturity date of the Notes. If there are two or more United States Treasury securities maturing on the maturity date of the Notes or two or more United States Treasury securities meeting the criteria of the preceding sentence, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The trustee will not be responsible or liable for determining, confirming, or verifying the redemption price.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed. Any exercise of our option to redeem the Notes will be done in compliance with the 1940 Act.

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the trustee deems appropriate and fair with the prior written consent of the Company. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the Note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC, Euroclear or Clearstream (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary.

Unless we default in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes or portions thereof called for redemption.

Offer to Repurchase Upon a Change of Control Repurchase Event

If a Change of Control Repurchase Event occurs, unless we have exercised our right to redeem the Notes in full, we will make an offer to each holder of Notes to repurchase all or any part (in minimum denominations of $2,000 and integral multiples of $1,000 principal amount thereabove) of that holder’s Notes at a repurchase price in cash equal to 100% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to the date of purchase. Within 30 days following any Change of Control Repurchase Event or, at our option, prior to any Change of Control, but after the public announcement of the Change of Control, we will

S-25

send a notice to each holder and the trustee describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is sent. The notice shall, if sent prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice. We will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

On the Change of Control Repurchase Event payment date, subject to extension if necessary to comply with the provisions of the 1940 Act, we will, to the extent lawful:

(1)accept for payment all Notes or portions of Notes properly tendered pursuant to our offer;

(2)deposit with the paying agent an amount equal to the aggregate purchase price in respect of all Notes or portions of Notes properly tendered; and

(3)deliver or cause to be delivered to the trustee the Notes properly accepted, together with an officers’ certificate stating the aggregate principal amount of Notes being purchased by us.

The paying agent will promptly remit to each holder of Notes properly tendered the purchase price for the Notes, and upon receipt of an authentication order, the trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided that each new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

We will not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and such third party purchases all Notes properly tendered and not withdrawn under its offer.

The source of funds that will be required to repurchase Notes in the event of a Change of Control Repurchase Event will be our available cash or cash generated from our operations or other potential sources, including funds provided by a purchaser in the Change of Control transaction, borrowings, sales of assets or sales of equity. We cannot assure you that sufficient funds from such sources will be available at the time of any Change of Control Repurchase Event to make required repurchases of Notes tendered. The terms of certain of our Credit Facilities provide that certain change of control events will constitute an event of default thereunder entitling the lenders to accelerate any indebtedness outstanding under the credit facility at that time and to terminate the credit facility. In addition, the documents governing the Unsecured Notes (with the exception of the 8.250% Unsecured Notes) and the 2022 Convertible Notes each contains a provision that would require us to offer to purchase the respective Unsecured Notes and 2022 Convertible Notes upon the occurrence of a fundamental change, such as a change in control. A failure to purchase any tendered Unsecured Notes or 2022 Convertible Notes would constitute an event of default under the applicable indenture or offering document, which would, in turn, constitute a default under certain of our Credit Facilities and the indenture. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition, Liquidity and Capital Resources” in our most recent Quarterly Report on Form 10-Q, which is incorporated by reference herein, for a general discussion of our indebtedness. Our future debt instruments may contain similar restrictions and provisions. If the holders of the Notes exercise their right to require us to repurchase Notes upon a Change of Control Repurchase Event, the financial effect of this repurchase could cause a default under our future debt instruments, even if the Change of Control Repurchase Event itself would not cause a default. It is possible that we will not have sufficient funds at the time of the Change of Control Repurchase Event to make the required repurchase of the Notes or our other debt. See “Supplementary Risk Factors—Risks Relating to the Notes—We may not be able to repurchase the Notes upon a Change of Control Repurchase Event.”

S-26

The definition of “Change of Control” includes a phrase relating to the direct or indirect sale, transfer, conveyance or other disposition of “all or substantially all” of our properties or assets and those of our subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise, established definition of the phrase under applicable law. Accordingly, the ability of a holder of Notes to require us to repurchase the Notes as a result of a sale, transfer, conveyance or other disposition of less than all of our assets and the assets of our subsidiaries taken as a whole to another person or group may be uncertain.

For purposes of the Notes:

“Below Investment Grade Rating Event” means the Notes are downgraded below Investment Grade by both Rating Agencies on any date from the date of the public notice of an arrangement that results in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended so long as the rating of the Notes is under publicly announced consideration for possible downgrade by either of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform us in writing that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event).

“Change of Control” means the occurrence of any of the following:

(1)the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation) in one or a series of related transactions, of all or substantially all of the assets of NMFC and its Controlled Subsidiaries taken as a whole to any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act), other than to any Permitted Holders; provided that, for the avoidance of doubt, a pledge of assets pursuant to any secured debt instrument of NMFC or its Controlled Subsidiaries shall not be deemed to be any such sale, lease, transfer, conveyance or disposition;

(2)the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) (other than any Permitted Holders) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of NMFC, measured by voting power rather than number of shares; or

(3)the approval by NMFC’s stockholders of any plan or proposal relating to the liquidation or dissolution of NMFC.

“Change of Control Repurchase Event” means the occurrence of a Change of Control and a Below Investment Grade Rating Event.

“Controlled Subsidiary” means any subsidiary of NMFC, 50% or more of the outstanding equity interests of which are owned by NMFC and its direct or indirect subsidiaries and of which NMFC possesses, directly or indirectly, the power to direct or cause the direction of the management or policies, whether through the ownership of voting equity interests, by agreement or otherwise.

“Fitch” means Fitch Ratings, Inc., also known as Fitch Ratings, or any successor thereto.

“Investment Grade” means a rating of BBB- or better by Fitch (or its equivalent under any successor rating categories of Fitch) and Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s) (or, in each case, if such Rating Agency ceases to rate the Notes for reasons outside of our control, the equivalent investment grade credit rating from any Rating Agency selected by us as a replacement Rating Agency).

“Moody’s” means Moody’s Investor Service, or any successor thereto.

S-27

“Permitted Holders” means (i) us, (ii) one or more of our Controlled Subsidiaries and (iii) New Mountain Finance Advisers, L.L.C. (formerly known as New Mountain Finance Advisers BDC, L.L.C.) or any affiliate of New Mountain Finance Advisers, L.L.C. that is organized under the laws of a jurisdiction located in the United States of America and in the business of managing or advising clients.

“Rating Agency” means:

(1)each of Fitch and Moody’s; and

(2)if any of Fitch or Moody’s ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” as defined in Section 3(a)(62) of the Exchange Act selected by us as a replacement agency for Fitch or Moody’s, or each of them, as the case may be.

“Voting Stock” as applied to stock of any person, means shares, interests, participations or other equivalents in the equity interest (however designated) in such person having ordinary voting power for the election of a majority of the directors (or the equivalent) of such person, other than shares, interests, participations or other equivalents having such power only by reason of the occurrence of a contingency.

Covenants

In addition to the covenants described in the base indenture, the following covenants shall apply to the Notes. To the extent of any conflict or inconsistency between the base indenture and the following covenants, the following covenants shall govern:

Merger, Consolidation or Sale of Assets

The indenture provides that we will not merge or consolidate with or into any other person (other than a merger of a wholly owned subsidiary into us), or sell, transfer, lease, convey or otherwise dispose of all or substantially all our property (provided that, for the avoidance of doubt, a pledge of assets pursuant to any secured debt instrument of NMFC or its Controlled Subsidiaries shall not be deemed to be any such sale, transfer, lease, conveyance or disposition) in any one transaction or series of related transactions unless:

•we are the surviving person (the “Surviving Person”) or the Surviving Person (if other than us) formed by such merger or consolidation or to which such sale, transfer, lease, conveyance or disposition is made shall be a corporation or limited liability company organized and existing under the laws of the United States of America or any state or territory thereof;

•the Surviving Person (if other than us) expressly assumes, by supplemental indenture in form reasonably satisfactory to the trustee, executed and delivered to the trustee by such Surviving Person, the due and punctual payment of the principal of, and premium, if any, and interest on, all the Notes outstanding, and the due and punctual performance and observance of all the covenants and conditions of the indenture to be performed by us;

•immediately before and immediately after giving effect to such transaction or series of related transactions, no default or event of default shall have occurred and be continuing; and

•we shall deliver, or cause to be delivered, to the trustee, an officers’ certificate and an opinion of counsel, each stating that such transaction and the supplemental indenture, if any, in respect thereto, comply with this covenant, that all conditions precedent in the indenture relating to such transaction have been complied with and that such supplemental indenture is valid, binding and enforceable against the successor company.

For the purposes of this covenant, the sale, transfer, lease, conveyance or other disposition of all the property of one or more of our subsidiaries, which property, if held by us instead of such subsidiaries, would constitute all or substantially all of our property on a consolidated basis, shall be deemed to be the transfer of all or substantially all of our property.

S-28

Although there is a limited body of case law interpreting the phrase “substantially all”, there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve “all or substantially all” of the properties or assets of a person. As a result, it may be unclear as to whether the merger, consolidation or sale of assets covenant would apply to a particular transaction as described above absent a decision by a court of competent jurisdiction. Although these types of transactions are permitted under the indenture, certain of the foregoing transactions could constitute a Change of Control that results in a Change of Control Repurchase Event permitting each holder to require us to repurchase the Notes of such holder as described above.

An assumption by any person of obligations under the Notes and the indenture might be deemed for U.S. federal income tax purposes to be an exchange of the Notes for new Notes by the holders thereof, resulting in recognition of gain or loss for such purposes and possibly other adverse tax consequences to the holders. Holders should consult their own tax advisors regarding the tax consequences of such an assumption.

Other Covenants

•We agree that for the period of time during which the Notes are outstanding, we will not violate, whether or not we are subject thereto, Section 18(a)(1)(A) as modified by Section 61(a) of the 1940 Act or any successor provisions, but giving effect, in either case, to any exemptive relief granted to us by the SEC.

•If, at any time, we are not subject to the reporting requirements of Sections 13 or 15(d) of the Exchange Act to file any periodic reports with the SEC, we agree to furnish to holders of the Notes and the trustee, for the period of time during which the Notes are outstanding, our audited annual consolidated financial statements, within 90 days of our fiscal year end, and unaudited interim consolidated financial statements, within 45 days of our fiscal quarter end (other than our fourth fiscal quarter). All such financial statements will be prepared, in all material respects, in accordance with GAAP, as applicable.

Events of Default

Each of the following is an event of default:

(1)default in the payment of any interest upon any Note when due and payable and the default continues for a period of 30 days;

(2)default in the payment of the principal of (or premium, if any, on) any Note when it becomes due and payable at its maturity, including upon any redemption date or required repurchase date;

(3)our failure for 60 consecutive days after written notice from the trustee or the holders of at least 25% in principal amount of the Notes then outstanding to us and the trustee, as applicable, has been received to comply with any of our other agreements contained in the Notes or indenture;

(4)default by us or any of our significant subsidiaries, as defined in Article 1, Rule 1-02 of Regulation S-X under the Exchange Act (but excluding any subsidiary which is (a) a non-recourse or limited recourse subsidiary, (b) a bankruptcy remote special purpose vehicle or (c) is not consolidated with NMFC for purposes of GAAP), with respect to any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of $50 million in the aggregate of us and/or any such subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable or (ii) constituting a failure to pay the principal or interest of any such debt when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, unless, in either case, such indebtedness is discharged, or such acceleration is rescinded, stayed or annulled, within a period of 30 calendar days after written notice of such failure is given to us by the trustee or to us and the trustee by the holders of at least 25% in aggregate principal amount of the Notes then outstanding;

(5)Pursuant to Section 18(a)(1)(C)(ii) and Section 61 of the 1940 Act, or any successor provisions, on the last business day of each of 24 consecutive calendar months, any class of securities shall have an asset coverage

S-29

(as such term is used in the 1940 Act) of less than 100%, giving effect to any amendments to such provisions of the 1940 Act or to any exemptive relief granted to us by the SEC; and

(6)certain events of bankruptcy, insolvency, or reorganization involving us occur and remain undischarged or unstayed for a period of 90 days.

If an event of default occurs and is continuing and a responsible officer of the Trustee has received written notice or has actual knowledge thereof, then and in every such case (other than an event of default specified in item (6) above) the trustee or the holders of at least 25% in principal amount of the outstanding Notes may declare the entire principal amount of Notes to be due and immediately payable, by a notice in writing to us (and to the trustee if given by the holders), and upon any such declaration such principal or specified portion thereof shall become immediately due and payable. Notwithstanding the foregoing, in the case of the events of bankruptcy, insolvency or reorganization described in item (6) above, 100% of the principal of and accrued and unpaid interest on the Notes will automatically become due and payable.

At any time after a declaration of acceleration with respect to the Notes has been made and before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding Notes, by written notice to us and the trustee, may rescind and annul such declaration and its consequences if (i) we have paid or deposited with the trustee a sum sufficient to pay all overdue installments of interest, if any, on all outstanding Notes, the principal of (and premium, if any, on) all outstanding Notes that have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates borne by or provided for in such Notes, to the extent that payment of such interest is lawful interest upon overdue installments of interest at the rate or rates borne by or provided for in such Notes, and all sums paid or advanced by the trustee and the reasonable compensation, expenses, disbursements and advances of the trustee, its agents and counsel, and (ii) all events of default with respect to the Notes, other than the nonpayment of the principal of (or premium, if any, on) or interest on such Notes that have become due solely by such declaration of acceleration, have been cured or waived. No such rescission will affect any subsequent default or impair any right consequent thereon.

No holder of Notes will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture, or for the appointment of a receiver or trustee, or for any other remedy under the indenture, unless:

(i)such holder has previously given written notice to the trustee of a continuing event of default with respect to the Notes;

(ii)the holders of not less than 25% in principal amount of the outstanding Notes shall have made written request to the trustee to institute proceedings in respect of such event of default;

(iii)such holder or holders have offered to the trustee security or indemnity, or both, satisfactory to the trustee against the costs, expenses and liabilities to be incurred in compliance with such request;

(iv)the trustee for 60 days after its receipt of such notice, request and offer of security and/or indemnity has failed to institute any such proceeding; and

(v)no direction inconsistent with such written request has been given to the trustee during such 60-day period by the holders of a majority in principal amount of the outstanding Notes.

Notwithstanding any other provision in the indenture, the holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any, on) and interest, if any, on such Note on the stated maturity or maturity expressed in such Note (or, in the case of redemption, on the redemption date or, in the case of repayment at the option of the holders, on the repayment date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such holder.

The trustee shall be under no obligation to exercise any of the rights or powers vested in it by the indenture at the request or direction of any of the holders of the Notes unless such holders shall have offered to the trustee security or indemnity satisfactory to the trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction. Subject to the foregoing, the holders of a majority in principal

S-30

amount of the outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the Notes, provided that (i) such direction shall not be in conflict with any rule of law or with this indenture, (ii) the trustee may take any other action deemed proper by the trustee that is not inconsistent with such direction and (iii) the trustee need not take any action that it determines in good faith may involve it in personal liability or be unjustly prejudicial (it being understood that the trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such holders) to the holders of Notes not consenting.

The holders of not less than a majority in principal amount of the outstanding Notes may on behalf of the holders of all of the Notes waive any past default under the indenture with respect to the Notes and its consequences, except a default (i) in the payment of (or premium, if any, on) or interest, if any, on any Note, or (ii) in respect of a covenant or provision of the indenture which cannot be modified or amended without the consent of the holder of each outstanding Note affected. Upon any such waiver, such default shall cease to exist, and any event of default arising therefrom shall be deemed to have been cured, for every purpose, but no such waiver shall extend to any subsequent or other default or event of default or impair any right consequent thereto.

We are required to deliver to the trustee, within 120 days after the end of each fiscal year (which fiscal year ends on December 31), an officers’ certificate stating that to the knowledge of the signers whether we are in default in the performance of any of the terms, provisions or conditions of the indenture.

Within 90 days after the occurrence of any default under the indenture with respect to the Notes, the trustee shall transmit notice of such default actually known to a responsible officer of the trustee, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any, on) or interest, if any, on any Note, the trustee shall be protected in withholding such notice if and so long as it in good faith determines that withholding of such notice is in the interest of the holders of the Notes.

Satisfaction and Discharge; Defeasance

We may satisfy and discharge our obligations under the indenture by delivering to the securities registrar for cancellation all outstanding Notes or by depositing with the trustee or delivering to the holders, as applicable, after the Notes have become due and payable, or otherwise, moneys sufficient to pay all of the outstanding Notes and paying all other sums payable under the indenture by us. Such discharge is subject to terms contained in the indenture.

In addition, the Notes are subject to defeasance and covenant defeasance, in each case, in accordance with the terms of the indenture. Defeasance means that, subject to the satisfaction of certain conditions, including, but not limited to, (i) depositing in trust for the benefit of the holders of the Notes a combination of money and/or U.S. government or U.S. government agency notes or bonds that will generate enough cash, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to make interest, principal and any other payments on the Notes on their various due dates and (ii) delivering to the trustee an opinion of counsel stating that (a) we have received from, or there has been published by, the Internal Revenue Service (the “IRS”) a ruling, or (b) since the date of execution of the Indenture, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon, the holders of the Notes and any coupons appertaining thereto will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred, we can legally release ourselves from all payment and other obligations on the Notes. Covenant defeasance means that, subject to the satisfaction of certain conditions, including, but not limited to, (i) depositing in trust for the benefit of the holders of the Notes a combination of money and/or U.S. government or U.S. government agency notes or bonds that will generate enough cash, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to make interest, principal and any other payments on the Notes on their various due dates and (ii) delivering to the trustee an opinion of counsel to the effect that the holders of the Notes and any coupons appertaining thereto will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at

S-31

the same times as would have been the case if such covenant defeasance had not occurred, we will be released from some of the restrictive covenants in the indenture.

Trustee

U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), is the trustee, security registrar and paying agent. U.S. Bank Trust Company, National Association, in its capacity, including without limitation as trustee, security registrar and paying agent, assumes no responsibility (or liability) for the accuracy, correctness, adequacy, or completeness of the information concerning us or our affiliates or any other party contained in this prospectus supplement and accompanying prospectus or the related documents or for any failure by us or any other party to disclose events that may have occurred and may affect the significance or accuracy of such information, or for any information provided to it by us, including but not limited to settlement amounts and any other information. Neither the trustee nor any paying agent shall be responsible for determining whether any Change of Control or Below Investment Grade Rating Event has occurred and whether any Change of Control offer with respect to the Notes is required.

We may maintain banking relationships in the ordinary course of business with the trustee and its affiliates.

“Corporate trust office” means the corporate trust office of the Trustee, at which at any particular time its corporate trust business with respect to the Indenture shall be administered, which office is currently located at: (i) for purposes of Section 1002 of the indenture, U.S. Bank Trust Company, National Association, 111 Fillmore Avenue, St. Paul, MN 55107, Attention: New Mountain Finance Corporation, and (ii) for all other purposes is located at 100 Wall Street, 6th Floor, New York, New York 10005, Attention: New Mountain Finance Corporation, or such other address as the Trustee may designate from time to time in accordance with the terms of the indenture.

In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation any act or provision of any present or future law or regulation or governmental authority, natural disaster, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, labor dispute, disease, epidemic or pandemic, quarantine, national emergency and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services, communications system failure, malware or ransomware or other unavailability of the Federal Reserve Bank wire or facsimile or telex system or other funds transfer system or other wire or communication facility or unavailability of any securities clearing system.”

Each of the trustee, security registrar, and paying agent will be entitled to those certain rights, privileges, immunities, indemnities, limitations of liability, and protections, as more fully set forth in the indenture.

Governing Law

The indenture provides that it and the Notes shall be governed by and construed in accordance with the laws of the State of New York, without regard to principles of conflicts of laws that would cause the application of laws of another jurisdiction.

Book-Entry, Settlement and Clearance

Global Notes

The Notes will be initially issued in the form of one or more registered Notes in global form, without interest coupons (the “Global Notes”). Upon issuance, each of the Global Notes will be deposited with the trustee as custodian for DTC and registered in the name of Cede & Co., as nominee of DTC.

S-32

Ownership of beneficial interests in a Global Note will be limited to persons who have accounts with DTC (“DTC participants”) or persons who hold interests through DTC participants. We expect that under procedures established by DTC:

•upon deposit of a Global Note with DTC’s custodian, DTC will credit portions of the principal amount of the Global Note to the accounts of the DTC participants designated by the underwriters; and

•ownership of beneficial interests in a Global Note will be shown on, and transfer of ownership of those interests will be effected only through, records maintained by DTC (with respect to interests of DTC participants) and the records of DTC participants (with respect to other owners of beneficial interests in the Global Note).

Beneficial interests in Global Notes may not be exchanged for Notes in physical, certificated form except in the limited circumstances described below.

Book-Entry Procedures for Global Notes

All interests in the Global Notes will be subject to the operations and procedures of DTC. We provide the following summary of those operations and procedures solely for the convenience of investors. The operations and procedures of DTC are controlled by that settlement system and may be changed at any time. Neither we, the trustee (in any of its capacities) nor the underwriters are responsible or liable for those operations or procedures.

DTC has advised us that it is:

•a limited purpose trust company organized under the laws of the State of New York;

•a “banking organization” within the meaning of the New York State Banking Law;

•a member of the Federal Reserve System;

•a “clearing corporation” within the meaning of the Uniform Commercial Code; and

•a “clearing agency” registered under Section 17A of the Exchange Act.

DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants. DTC’s participants include securities brokers and dealers, including the underwriters; banks and trust companies; clearing corporations and other organizations. Indirect access to DTC’s system is also available to others such as banks, brokers, dealers and trust companies; these indirect participants clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly. Investors who are not DTC participants may beneficially own securities held by or on behalf of DTC only through DTC participants or indirect participants in DTC.

So long as DTC’s nominee is the registered owner of a Global Note, that nominee will be considered the sole owner or holder of the Notes represented by that Global Note for all purposes under the indenture. Except as provided below, owners of beneficial interests in a Global Note:

•will not be entitled to have Notes represented by the Global Note registered in their names;

•will not receive or be entitled to receive physical, certificated Notes; and

•will not be considered the owners or holders of the Notes under the indenture for any purpose, including with respect to receiving notices or the giving of any direction, instruction or approval to the trustee under the indenture.

As a result, each investor who owns a beneficial interest in a Global Note must rely on the procedures of DTC to exercise any rights of a holder of Notes under the indenture (and, if the investor is not a participant or an indirect participant in DTC, on the procedures of the DTC participant through which the investor owns its interest).

S-33

Payments of principal and interest with respect to the Notes represented by a Global Note will be made by the trustee to DTC’s nominee as the registered holder of the Global Note. Neither we nor the trustee will have any responsibility or liability for the payment of amounts to owners of beneficial interests in a Global Note, for any aspect of the records relating to or payments made on account of those interests by DTC, or for maintaining, supervising or reviewing any records of DTC relating to those interests.

Payments by participants and indirect participants in DTC to the owners of beneficial interests in a Global Note will be governed by standing instructions and customary industry practice and will be the responsibility of those participants or indirect participants and DTC.

Cross-market transfers of beneficial interests in Global Notes between DTC participants, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected within DTC through the DTC participants that are acting as depositaries for Euroclear and Clearstream. To deliver or receive an interest in a Global Note held in a Euroclear or Clearstream account, an investor must send transfer instructions to Euroclear or Clearstream, as the case may be, under the rules and procedures of that system and within the established deadlines of that system. If the transaction meets its settlement requirements, Euroclear or Clearstream, as the case may be, will send instructions to its DTC depositary to take action to effect final settlement by delivering or receiving interests in the relevant Global Notes in DTC, and making or receiving payment under normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream participants may not deliver instructions directly to the DTC depositaries that are acting for Euroclear or Clearstream.

Because the settlement of cross-market transfers takes place during New York business hours, DTC participants may employ their usual procedures for sending securities to the applicable DTC participants acting as depositaries for Euroclear and Clearstream. The sale proceeds will be available to the DTC participant seller on the settlement date. Thus, to a DTC participant, a cross-market transaction will settle no differently from a trade between two DTC participants. Because of time zone differences, the securities account of a Euroclear or Clearstream participant that purchases an interest in a Global Note from a DTC participant will be credited on the business day for Euroclear or Clearstream immediately following the DTC settlement date. Cash received in Euroclear or Clearstream from the sale of an interest in a Global Note to a DTC participant will be reflected in the account of the Euroclear of Clearstream participant the following business day, and receipt of the cash proceeds in the Euroclear or Clearstream participant’s account will be back-valued to the date on which settlement occurs in New York. DTC, Euroclear and Clearstream have agreed to the above procedures to facilitate transfers of interests in the Global Notes among participants in those settlement systems. However, the settlement systems are not obligated to perform these procedures and may discontinue or change these procedures at any time. Neither we nor the trustee will have any responsibility or liability for the performance by DTC, Euroclear or Clearstream or their participants or indirect participants of their obligations under the rules and procedures governing their operations, including maintaining, supervising or reviewing the records relating to, or payments made on account of, beneficial ownership interests in Global Notes.

Transfers between participants in DTC will be effected under DTC’s procedures and will be settled in same-day funds.

Certificated Notes

Notes in physical, certificated form will be in fully registered form and issued and delivered to each person that DTC identifies as a beneficial owner of the related Notes only if:

•DTC notifies us at any time that it is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days;

•DTC ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days; or

•an event of default with respect to the Notes has occurred and is continuing and such beneficial owner requests that its Notes be issued in physical, certificated form.

S-34

In connection with any proposed exchange of a certificated Note for a Global Note, there shall be provided to the trustee, upon reasonable request therefore, all information necessary to allow the trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Internal Revenue Code Section 6045. The trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

S-35

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

The following summary describes certain U.S. federal income tax consequences applicable to an investment in the Notes. This summary does not purport to be a complete description of the U.S. federal income tax considerations applicable to such an investment. The summary is based upon the Code, U.S. Treasury regulations, and administrative and judicial interpretations, each as of the date of this prospectus supplement and all of which are subject to change, potentially with retroactive effect, or to different interpretations. We cannot assure you that the IRS will not challenge one or more of the tax consequences described in this summary, and we have not obtained, nor do we intend to obtain, any ruling from the IRS or opinion of counsel with respect to the tax consequences of an investment in the Notes. Investors should consult their own tax advisors with respect to tax considerations that pertain to their investment in the Notes.

This summary discusses only Notes held as capital assets within the meaning of the Code (generally, property held for investment purposes) and does not purport to address persons in special tax situations, such as banks and other financial institutions, insurance companies, personal holding companies, controlled foreign corporations, passive foreign investment companies, real estate investment trusts and RICs (and shareholders of such corporations), corporations that accumulate earnings to avoid U.S. federal income tax, dealers in securities or currencies, traders in securities, former citizens or long-term residents of the United States, persons holding the Notes as a position in a “straddle,” “hedge,” “constructive sale transaction,” “conversion transaction,” “wash sale” or other integrated transaction for U.S. federal income tax purposes, entities that are tax-exempt for U.S. federal income tax purposes, retirement plans, individual retirement accounts, tax-deferred accounts, persons subject to the alternative minimum tax, pass-through entities (including partnerships and entities and arrangements classified as partnerships for U.S. federal income tax purposes) and beneficial owners of pass-through entities, or U.S. holders (as defined below) whose functional currency (as defined in the Code) is not the U.S. dollar. It also does not address beneficial owners of the Notes other than original purchasers of the Notes who acquire the Notes in this offering for cash at a price equal to their issue price (i.e., the first price at which a substantial amount of the Notes is sold for money to investors (other than to bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placements agents or wholesalers)). This discussion also does not address the U.S. federal income tax consequences to beneficial owners of the Notes subject to the special tax accounting rules under Section 451(b) of the Code. In addition, this summary only addresses U.S. federal income tax consequences, and does not address other U.S. federal tax consequences, including, for example, estate or gift tax consequences. This summary also does not address any U.S. state or local or non-U.S. tax consequences. Investors considering purchasing the Notes should consult their own tax advisors concerning the application of the U.S. federal income tax laws to their individual circumstances, as well as any consequences to such investors relating to purchasing, owning and disposing of the Notes under the laws of any state, local, foreign or other taxing jurisdiction.

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of a Note that is, for U.S. federal income tax purposes:

•an individual who is a citizen or resident of the United States;

•a corporation (or other entity treated as a corporation) created or organized in or under the laws of the United States, any state thereof, or the District of Columbia;

•a trust (i) the administration of which is subject to the primary supervision of a U.S. court and that has one or more “United States persons” (within the meaning of the Code) that have the authority to control all substantial decisions of the trust or (ii) that has made a valid election under applicable U.S. Treasury regulations to be treated as a “United States person” (within the meaning of the Code); or

•an estate the income of which is subject to U.S. federal income taxation regardless of its source.

A “Non-U.S. holder” is a beneficial owner of a Note that is neither a U.S. holder nor a partnership for U.S. federal income tax purposes.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds any Notes, the U.S. federal income tax treatment of a partner in the partnership generally will

depend upon the status of the partner, the activities of the partnership and certain determinations made at the partner level. Partnerships holding Notes, and persons holding interests in such partnerships, should each consult their own tax advisors as to the consequences of investing in the Notes in their individual circumstances.

Taxation of U.S. Holders

Payments of Interest

The following discussion assumes that the Notes will be issued with no original issue discount or a de minimis amount of original issue discount for U.S. federal income tax purposes. Payments or accruals of interest on a Note generally will be taxable to a U.S. holder as ordinary interest income at the time they are received (actually or constructively) or accrued, in accordance with the U.S. holder’s regular method of tax accounting.

Sale, Exchange, Redemption, Retirement or Other Taxable Disposition of a Note

Upon the sale, exchange, redemption, retirement or other taxable disposition of a Note, a U.S. holder generally will recognize capital gain or loss equal to the difference between the amount realized on the sale, exchange, redemption, retirement or other taxable disposition (excluding amounts representing accrued and unpaid interest, which are treated as ordinary interest income to the extent not previously included in income) and the U.S. holder’s adjusted tax basis in the Note. A U.S. holder’s adjusted tax basis in a Note generally will equal the U.S. holder’s initial investment in the Note. Capital gain or loss generally will be long-term capital gain or loss if the Note was held for more than one year. Long-term capital gains recognized by individuals and certain other non-corporate U.S. holders generally are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations under the Code.

Additional Tax on Net Investment Income

An additional tax of 3.8% is imposed on certain “net investment income” (or “undistributed net investment income,” in the case of certain U.S. holders that are estates and trusts) received by certain U.S. holders with adjusted gross income above certain threshold amounts. “Net investment income” generally includes interest payments on, and gain recognized from the sale, exchange, redemption, retirement or other taxable disposition of, the Notes, less certain deductions. U.S. holders should consult their own tax advisors regarding the effect, if any, of this tax on their ownership and disposition of the Notes.

Backup Withholding and Information Reporting

A U.S. holder may be subject to information reporting and backup withholding when such U.S. holder receives interest payments on the Notes or proceeds upon the sale or other disposition of such Notes (including a redemption or retirement of the Notes). Certain U.S. holders, such as corporations, are exempt from information reporting or backup withholding but may be required to certify their exempt status. A U.S. holder will be subject to backup withholding if such U.S. holder is not otherwise exempt and such U.S. holder:

•fails to furnish the U.S. holder’s taxpayer identification number (“TIN”), which, for an individual, generally is his or her social security number;

•furnishes an incorrect TIN;

•is notified by the IRS that the U.S. holder has failed properly to report payments of interest or dividends; or

•fails to certify, under penalties of perjury, on an IRS Form W-9 (Request for Taxpayer Identification Number and Certification) or a suitable substitute form (or other applicable certificate), that the U.S. holder has furnished a correct TIN and that the IRS has not notified the U.S. holder that the U.S. holder is subject to backup withholding.

U.S. holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption, if applicable. Backup withholding is not an

S-37

additional tax, and taxpayers may use amounts withheld as a credit against their U.S. federal income tax liability or may claim a refund if they timely provide certain information to the IRS.

Taxation of Non-U.S. Holders

The following is a summary of certain U.S. federal income tax consequences that will apply to you if you are a “Non-U.S. holder” of a Note.

Interest on the Notes

Generally, stated interest paid or accrued to a Non-U.S. holder that is not effectively connected with the Non-U.S. holder’s conduct of a trade or business within the United States (a “U.S. trade or business”) is subject to withholding tax at a rate of 30% (or, if applicable, a lower treaty rate). Nevertheless, and subject to the discussion below concerning backup withholding and FATCA, interest paid or accrued on a Note to a Non-U.S. holder that is not effectively connected with the Non-U.S. holder’s conduct of a U.S. trade or business generally will not be subject to U.S. federal withholding tax provided that:

•such Non-U.S. holder does not directly, indirectly or constructively own 10% or more of the total combined voting power of all classes of our voting stock;

•such Non-U.S. holder is neither a controlled foreign corporation that is related to us through sufficient direct, indirect or constructive stock ownership (under the Code) nor a bank that received interest on the Note on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business; and

•one of the following applies: (1) the Non-U.S. holder certifies, prior to the payment of interest, in a statement (generally, a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, or a suitable substitute) provided to us or the paying agent, under penalties of perjury, that it is the beneficial owner of the Notes and not a “United States person” within the meaning of the Code and provides its name and address, (2) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business and holds the Note on behalf of the Non-U.S. holder certifies to us or the paying agent under penalties of perjury that it, or the financial institution between it and the Non-U.S. holder, has received from the Non-U.S. holder a statement, under penalties of perjury, that such Non-U.S. holder is the beneficial owner of the Notes and is not a United States person and provides us or the paying agent with a copy of such statement or (3) the Non-U.S. holder holds its Note through a “qualified intermediary” and certain conditions are satisfied.

Even if the above conditions are not met, a Non-U.S. holder generally will be entitled to a reduction in or an exemption from U.S. federal withholding tax on interest if the Non-U.S. holder provides us or our paying agent, prior to the payment of interest, with a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, or a suitable substitute form claiming an exemption from or reduction of the U.S. federal withholding tax under the benefit of an income tax treaty between the United States and the Non-U.S. holder’s country of residence. A Non-U.S. holder is required to inform the recipient of any change in the information on such statement within 30 days of such change. Special certification rules apply if a Non-U.S. holder holds its Note through a pass-through entity.

If any interest on the Notes is effectively connected with a Non-U.S. holder’s conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, such Non-U.S. holder maintains a permanent establishment in the United States to which such interest or gain is attributable), then the interest income generally will be subject to U.S. federal income tax at regular graduated income tax rates in the same manner as if such Non-U.S. holder were a U.S. holder (but without regard to the additional tax on net investment income described above). Such effectively connected interest income will not be subject to U.S. federal withholding tax if a Non-U.S. holder satisfies certain certification requirements by providing to the applicable withholding agent a properly executed IRS Form W-8ECI (or successor form). In addition, if a Non-U.S. holder is a corporation, the portion of such Non-U.S. holder’s earnings and profits that are effectively connected with such Non-U.S. holder’s conduct of a U.S. trade or

S-38

business may also be subject to a “branch profits tax” at a 30% rate, unless an applicable income tax treaty provides for a lower rate.

Disposition of the Notes

Subject to the discussions of backup withholding and FATCA withholding below, a Non-U.S. holder generally will not be subject to U.S. federal income tax on any gain realized on the sale, redemption, exchange, retirement, or other taxable disposition of a Note unless:

•the gain is effectively connected with the conduct by such Non-U.S. holder of a U.S. trade or business (and, if required by an applicable income tax treaty, such Non-U.S. holder maintains a permanent establishment in the United States to which such gain is attributable);

•such Non-U.S. holder is an individual who has been present in the United States for 183 days or more in the taxable year of disposition but is not considered a resident of the United States under the Code, certain other requirements are met, and the Non-U.S. holder is not eligible for relief under an applicable income tax treaty; or

•a portion of the gain is attributable to accrued but unpaid interest, in which case such portion would be subject to the tax rules described above in “— Interest on the Notes.”

If a Non-U.S. holder’s gain is described in the first bullet point above, such Non-U.S. holder generally will be subject to U.S. federal income tax on the net gain derived from the sale or other taxable disposition generally in the same manner as if such Non-U.S. holder were a U.S. holder, and if such Non-U.S. holder is a foreign corporation, it may also be required to pay an additional branch profits tax at a 30% rate (or a lower rate if so specified by an applicable income tax treaty). A Non-U.S. holder described in the second bullet point above will be subject to U.S. federal income tax at a 30% rate (or lower applicable income tax treaty rate) on the gain derived from the sale or other disposition, which may be offset by certain U.S. source capital losses.

Certain other exceptions may be applicable, and Non-U.S. holders should consult their own tax advisors with regard to whether taxes will be imposed on capital gain in their individual circumstances.

Backup Withholding and Information Reporting

The amount of interest that we pay to any Non-U.S. holder on the Notes will be reported to the Non-U.S. holder and to the IRS annually on an IRS Form 1042-S, regardless of whether any tax was actually withheld. Copies of these information returns may also be made available under the provisions of a specific income tax treaty or agreement to the tax authorities of the country in which the Non-U.S. holder resides. However, a Non-U.S. holder generally will not be subject to backup withholding and certain other information reporting with respect to payments that we make to the Non-U.S. holder, provided that we do not have actual knowledge or reason to know that such Non-U.S. holder is a “United States person,” within the meaning of the Code, and the Non-U.S. holder has given us the statement described above under “— Interest on the Notes.”

If a Non-U.S. holder sells or exchanges a Note through a United States broker or the United States office of a foreign broker or such sale is deemed to occur through a United States office of a foreign broker, the proceeds from such sale or exchange will be subject to information reporting and backup withholding unless the Non-U.S. holder provides a withholding certificate or other appropriate documentary evidence establishing that such holder is not a U.S. holder to the broker and such broker does not have actual knowledge or reason to know that such holder is a U.S. holder, or the Non-U.S. holder is an exempt recipient (as that term is defined in Treas. Reg. § 1.6049-4(c)(1)(ii)) eligible for an exemption from information reporting and backup withholding. If a Non-U.S. holder sells or exchanges a Note through the foreign office of a broker who is a United States person or a U.S. middleman (as that that term is defined under applicable Treasury Regulations), the proceeds from such sale or exchange will be subject to information reporting unless the Non-U.S. holder provides to such broker a withholding certificate or other documentary evidence establishing that such holder is not a U.S. holder and such broker does not have actual knowledge or reason to know that such withholding certificate or documentary evidence is false, or the Non-U.S. holder is an exempt recipient (as that term is defined in Treas. Reg. § 1.6049-4(c)(1)(ii)) eligible for an

S-39

exemption from information reporting. In circumstances where information reporting by the foreign office of such a broker is required, backup withholding will be required only if the broker has actual knowledge that the holder is a U.S. holder.

A Non-U.S. holder generally will be entitled to credit any amounts withheld under the backup withholding rules against the Non-U.S. holder’s U.S. federal income tax liability or may claim a refund provided that the required information is furnished to the IRS in a timely manner.

Non-U.S. holders are urged to consult their tax advisors regarding the application of information reporting and backup withholding in their particular situations, the availability of an exemption therefrom, and the procedures for obtaining such an exemption, if available.

FATCA

Legislation commonly referred to as the “Foreign Account Tax Compliance Act,” or “FATCA,” generally imposes a 30% withholding tax on payments of certain types of income to foreign financial institutions (“FFIs”) unless such FFIs either (i) enter into an agreement with the U.S. Treasury to report certain required information with respect to accounts held by certain specified U.S. persons (or held by foreign entities that have certain specified U.S. persons as substantial owners) or (ii) reside in a jurisdiction that has entered into an intergovernmental agreement (“IGA”) with the United States to collect and share such information and are in compliance with the terms of such IGA and any enabling legislation or regulations. The types of income subject to the tax include U.S. source interest (including interest on a Note) and dividends. While the Code would also require withholding on payments of the gross proceeds from the sale of any property that could produce U.S. source interest or dividends, such as the Notes, the U.S. Treasury Department has indicated its intent to eliminate this requirement in proposed regulations, which state that taxpayers may rely on the proposed regulations until final regulations are issued. The information required to be reported includes the identity and taxpayer identification number of each account holder that is a specified U.S. person and financial information associated with the holder’s account. In addition, subject to certain exceptions, this legislation also imposes a 30% withholding on payments of certain types of income, as described above, to certain foreign entities that are not FFIs unless the foreign entity certifies that it does not have a greater than 10% owner that is a specified U.S. person or provides the withholding agent with identifying information on each greater than 10% owner that is a specified U.S. person. Depending on the status of a beneficial owner and the status of the intermediary through which it holds the Notes, a beneficial owner could be subject to this 30% withholding tax with respect to interest paid on the Notes. Under certain circumstances, a beneficial owner might be eligible for a refund or credit of such taxes. We will not pay any additional amounts to holders of the Notes in respect of any amounts withheld.

Holders and beneficial owners should consult their own tax advisors regarding FATCA and whether it may be relevant to their acquisition, ownership and disposition of the Notes.

You should consult your own tax advisor with respect to the particular tax consequences to you of an investment in the Notes, including the possible effect of any pending legislation or proposed regulations.

Subject to the terms and conditions set forth in an underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the aggregate principal amount of Notes set forth opposite its name below.


Underwriters						Principal Amount of Notes
SMBC Nikko Securities America, Inc.						$
Deutsche Bank Securities Inc.
Goldman Sachs & Co. LLC
Wells Fargo Securities, LLC
Total						$

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the Notes sold under the underwriting agreement if any of these Notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”), or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the Notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the Notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officers’ certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The following table shows the per Note and total underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering.


	Per Note	Total
Public offering price	%	$
Underwriting discount (sales load)	%	$
Proceeds to us, before expenses	%	$

The underwriters propose to offer some of the Notes to the public at the public offering price set forth on the cover page of this prospectus supplement, and some of the Notes to certain other Financial Industry Regulatory Authority, or FINRA, members at the public offering price less a concession not in excess of % of the aggregate principal amount of the Notes. The underwriters may allow, and the dealers may reallow, a discount not in excess of % of the aggregate principal amount of the Notes. After the initial offering of the Notes to the public, the public offering price and such concessions may be changed. No such change shall change the amount of proceeds to be received by us as set forth on the cover page of this prospectus supplement.

The expenses of the offering, not including the underwriting discount, are estimated at $ and are payable by us.

S-41

No Sales of Similar Securities

Subject to certain exceptions, we have agreed not to directly or indirectly, offer, pledge. sell, contract to sell, grant any option for the sale of or otherwise transfer or dispose of any debt securities issued or guaranteed by us or any securities convertible into or exercisable or exchangeable for debt securities issued or guaranteed by us or file any registration statement under the Securities Act with respect to any of the foregoing through the closing date without first obtaining the written consent of the representative of the underwriters. This consent may be given at any time without public notice.

Listing

The Notes are a new issue of securities with no established trading market. The Notes will not be listed on any securities exchange or quoted on any automated dealer quotation system.

We have been advised by certain of the underwriters that they currently intend to make a market in the Notes after completion of this offering as permitted by applicable laws and regulations. The underwriters are not obligated, however, to make a market in the Notes and any such market-making may be discontinued at any time in the sole discretion of the underwriters without any notice. Accordingly, no assurance can be given as to the liquidity of, or development of a public trading market for, the Notes. If an active public trading market for the Notes does not develop, the market price and liquidity of the Notes may be adversely affected.

Price Stabilization, Short Positions

In connection with the offering, certain of the underwriters may purchase and sell Notes in the open market. These transactions may include over-allotment, covering transactions and stabilizing transactions. Over-allotment involves sales of Notes in excess of the aggregate principal amount of the Notes to be purchased by the underwriters in the offering, which creates a short position for the underwriters. Covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions consist of certain bids or purchases of Notes made for the purpose of preventing or retarding a decline in the market price of the Notes while the offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representative has repurchased Notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

Any of these activities may cause the price of the Notes to be higher than the price that otherwise would exist in the open market in the absence of such transactions. These transactions may be effected in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time without any notice relating thereto.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Notes. In addition, neither we nor any of the underwriters make any representation that the representative will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage, valuation services and other financial and non-financial activities and services. Certain of the underwriters and their respective affiliates have provided, currently provide, and may in the future provide, a variety of these services to us and to persons and entities with relationships with us, for which they received or will receive customary fees and expenses. Certain of the underwriters and their affiliates were underwriters in connection with our securities offerings, for which they received customary fees.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade

S-42

securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to our assets, securities or instruments (directly, as collateral securing other obligations, or otherwise) or persons and entities with relationships with us. Certain of the underwriters and their affiliates that have a lending relationship with us routinely hedge their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long or short positions in such assets, securities and instruments.

We intend to use all of the net proceeds from the sale of the Notes to repay existing indebtedness outstanding under the Holdings Credit Facility, the NMFC Credit Facility, and the DB Credit Facility. Affiliates of certain underwriters are lenders under each of the Holdings Credit Facility, the NMFC Credit Facility, and the DB Credit Facility. Accordingly, affiliates of certain of the underwriters may receive more than 5% of the proceeds of this offering to the extent the proceeds are used to pay down a portion of the outstanding indebtedness under the Holdings Credit Facility, the NMFC Credit Facility, and the DB Credit Facility.

Settlement

We expect that delivery of the Notes will be made to investors on or about , 2024, which will be the business day following the date hereof. Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes prior to the date of delivery hereunder will be required by virtue of the fact that the Notes initially settle in T+ , to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes prior to the date of delivery hereunder should consult their advisors.

These resale restrictions may under certain circumstances apply to resales of the Notes outside of Canada.

Representations of Purchasers

Taxation and Eligibility for Investment

Any discussion of taxation and related matters contained in this prospectus supplement does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a Canadian investor when deciding to purchase the Notes and, in particular, does not address any Canadian tax considerations. No representation or warranty is hereby made as to the tax consequences to a resident, or deemed resident, of Canada of an investment in the Notes or with respect to the eligibility of the Notes for investment by such investor under relevant Canadian federal and provincial legislation and regulations.

Rights of Action for Damages or Rescission

Securities legislation in certain of the Canadian jurisdictions provides certain purchasers of securities pursuant to an offering memorandum (such as this prospectus supplement), including where the distribution involves an “eligible foreign security” as such term is defined in Ontario Securities Commission Rule 45-501 Ontario Prospectus and Registration Exemptions and in Multilateral Instrument 45-107 Listing Representation and Statutory Rights of Action Disclosure Exemptions, as applicable, with a remedy for damages or rescission, or both, in addition to any other rights they may have at law, where the offering memorandum, or other offering document that constitutes an offering memorandum, and any amendment thereto, contains a “misrepresentation” as defined under applicable Canadian securities laws. These remedies, or notice with respect to these remedies, must be exercised or delivered, as the case may be, by the purchaser within the time limits prescribed under, and are subject to limitations and defences under, applicable Canadian securities legislation. In addition, these remedies are in addition to and without derogation from any other right or remedy available at law to the investor.

New Mountain Finance Corporation

Debt Securities

New Mountain Finance Corporation (“NMFC”, the “Company”, “we”, “us” and “our”) is a Delaware corporation that was originally incorporated on June 29, 2010 and completed its initial public offering (“IPO”) on May 19, 2011. We are a closed-end, non-diversified management investment company that has elected to be regulated as a business development company under the Investment Company Act of 1940, as amended (the “1940 Act”). Our investment objective is to generate current income and capital appreciation through the sourcing and origination of debt securities at all levels of the capital structure, primarily consisting of senior secured loans, and select junior capital positions, to growing businesses in defensive industries that offer attractive risk-adjusted returns. Our first lien debt may include traditional first lien senior secured 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. Unitranche loans generally allow the borrower to make a large lump sum payment of principal at the end of the loan term and there is a heightened risk of loss if the borrower is unable to pay the lump sum or refinance the amount owed at maturity. In some cases, our investments may also include equity interests. Our primary focus is in the debt of defensive growth companies, which are defined as generally exhibiting 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.

The investments that we invest in are almost entirely rated below investment grade or may be unrated, which are often referred to as “leveraged loans”, “high yield” or “junk” debt investments, and may be considered “high risk” or speculative compared to debt investments that are rated investment grade. 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 our net asset value (“NAV”) and income distributions. Our investments are also primarily floating rate debt investments that contain interest reset provisions that may make it more difficult for borrowers to make debt repayments to us if interest rates rise. In addition, some of our 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. Our debt investments may also lose significant market value before a default occurs. Furthermore, an active trading market may not exist for these securities. This illiquidity may make it more difficult to value our investments.

We may offer, from time to time, in one or more offerings or series, our common stock, preferred stock, subscription rights to purchase shares of common stock, debt securities or warrants representing rights to purchase shares of our common stock, preferred stock or debt securities, which we refer to, collectively, as the “securities”. The preferred stock, subscription rights, debt securities and warrants offered hereby may be convertible or exchangeable into shares of common stock. The securities may be offered at prices and on terms to be described in one or more supplements to this prospectus.

In the event we offer common stock, the offering price per share of our common stock less any underwriting discounts or commissions will generally not be less than the NAV per share of our common stock at the time we make the offering. However, we may issue shares of our common stock pursuant to this prospectus at a price per share that is less than our NAV per share (i) in connection with a rights offering to our existing stockholders, (ii) with the prior approval of the majority (as defined in the 1940 Act) of our common stockholders or (iii) under such other circumstances as the SEC may permit.

The securities may be offered directly to one or more purchasers, including to existing stockholders in a rights offering, through agents designated from time to time by us, or to or through underwriters or dealers. Each prospectus supplement relating to an offering will identify any agents or underwriters involved in the sale of the securities, and will disclose any applicable purchase price, fee, discount or commissions arrangement between us and our agents or underwriters or among our underwriters or the basis upon which such amount may be calculated. See “Plan of Distribution” in this prospectus. We may not sell any of the securities through agents, underwriters or dealers without delivery of this prospectus and a prospectus supplement describing the method and terms of the offering of such securities.

Our common stock is traded on the NASDAQ Global Select Market (the “NASDAQ”) under the symbol “NMFC”. On June 24, 2024, the last reported sales price on the NASDAQ for our common stock was $12.23 per share.

An investment in our securities is very risky and highly speculative. Shares of closed-end investment companies, including BDCs, frequently trade at a discount to their NAV. In addition, the companies in which we invest are subject to special risks. See “Risk Factors” beginning on page 18 of this prospectus, in Part I, Item 1A of our most recent Annual Report on Form 10-K, in Part II, Item 1A of our most recent Quarterly Report on Form 10-Q and in, or incorporated by reference into, the applicable prospectus supplement and in any free writing prospectuses we may authorize for use in connection with a specific offering, and under similar headings in the other documents that are incorporated by reference into this prospectus, to read about factors you should consider, including the risk of leverage, before investing in our securities.

Neither the SEC nor any state securities commission has approved or disapproved of these securities, or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

This prospectus may not be used to consummate sales of our securities unless accompanied by a prospectus supplement.

This prospectus describes some of the general terms that may apply to an offering of our securities. We will provide the specific terms of these offerings and securities in one or more supplements to this prospectus. We may also authorize one or more free writing prospectuses to be provided to you in connection with these offerings. The prospectus supplement and any related free writing prospectus may also add, update, or change information contained in this prospectus.

Overview

We are a Delaware corporation that was originally incorporated on June 29, 2010 and completed our initial public offering (“IPO”) on May 19, 2011. 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”). As such, we are obligated to comply with certain regulatory requirements. We have elected to be treated, 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”). Since our IPO, and through March 31, 2024, we have raised approximately $1,014.8 million in net proceeds from additional offerings of our common stock.

The Investment Adviser is a wholly-owned subsidiary of 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 approximately $50 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. The Administrator provides the administrative services necessary to conduct our day-to-day operations.

We make investments through both primary originations and open-market secondary purchases. We primarily target loans to, and invest in, U.S. middle market businesses, a market segment we believe continues to be underserved by other lenders. 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 (v) seasoned management teams. Similar to us, the investment objective of SBIC I and SBIC II e is to generate current income and capital appreciation under our investment criteria. However, SBIC I and SBIC II investments must be in SBA eligible small businesses. Our portfolio may be concentrated in a limited number of industries. As of March 31, 2024, our top five industry concentrations were software, business services, healthcare, investment funds (which includes our investments in joint ventures) and education.

active trading market may not exist for these securities. This illiquidity may make it more difficult to value our investments.

As of March 31, 2024, our NAV was approximately $1,356.9 million and our portfolio had a fair value of approximately $3,070.0 million in 114 portfolio companies. At March 31, 2024 and December 31, 2023, our weighted average yield to maturity at cost for income producing investments (“YTM at Cost”) was approximately 11.1% and 10.9%, respectively. This YTM at Cost calculation assumes that all investments, including secured collateralized agreements, not on non-accrual are purchased at cost on the quarter end date and held until their respective maturities with no prepayments or losses and exited at par at maturity.

At March 31, 2024 and December 31, 2023, our weighted average yield to maturity at cost for all investments (“YTM at Cost for Investments”) was approximately 9.5% and 9.7%, respectively. This YTM at Cost for Investments calculation assumes that all investments, including secured collateralized agreements, are purchased at cost on the quarter end date and held until their respective maturities with no prepayments or losses and exited at par at maturity. YTM at Cost and YTM at Cost for Investments calculations exclude the impact of existing leverage. YTM at Cost and YTM at Cost for Investments use the London Interbank Offered Rate (“LIBOR”), Sterling Overnight Interbank Average Rate (“SONIA”), Secured Overnight Financing Rate (“SOFR”) and Euro Interbank Offered Rate (“EURIBOR”) curves at each quarter’s end date. The actual yield to maturity may be higher or lower due to the future selection of the SONIA, SOFR, and EURIBOR contracts by the individual companies in our portfolio or other factors.

The Investment Adviser

The Investment Adviser is managed by a six member investment committee (the “Investment Committee”), which is responsible for approving purchases and sales of our investments above $10.0 million in aggregate by issuer. The Investment Committee currently consists of Steven B. Klinsky, Robert A. Hamwee, John R. Kline, Adam B. Weinstein and Laura C. Holson. The sixth and final member of the Investment Committee will consist of a New Mountain Capital Managing Director who will hold the position on the Investment Committee on an annual rotating basis. A. Joe Delgado served on the Investment Committee from August 2022 to July 2023. Beginning in August 2023, Andre V. Moura was appointed to the Investment Committee for a one-year term. Effective January 1, 2023, Laura C. Holson joined the Investment Committee as a new permanent member. In addition, our executive officers and certain investment professionals of the Investment Adviser are invited to all Investment Committee meetings. Purchases and dispositions below $10.0 million may be approved by our Chief Executive Officer. These approval thresholds are subject to change over time. We expect to benefit from the extensive and varied relevant experience of the investment professionals serving on the Investment Committee, which includes expertise in private equity, primary and secondary leveraged credit, private mezzanine finance and distressed debt.

Competitive Advantages

We believe that we have the following competitive advantages over other capital providers to middle market companies:

Proven and Differentiated Investment Style With Areas of Deep Industry Knowledge

defensive growth niches of the middle market space where we believe few debt funds have built equivalent research and operational size and scale.

We benefit directly from New Mountain Capital’s private equity investment strategy that seeks to identify attractive investment sectors from the top down and then works to become a well positioned investor in these sectors. New Mountain Capital focuses on companies and industries with sustainable strengths in all economic cycles, particularly ones that are defensive in nature, that have secular tailwinds and can maintain pricing power in the midst of a recessionary and/or inflationary environment. New Mountain Capital focuses on companies within sectors in which it has significant expertise (examples include software, education, niche healthcare, business services, consumer services and distribution & logistics) while typically avoiding investments in companies with products or services that serve markets that are highly cyclical, have the potential for long-term decline, are overly-dependent on consumer demand or are commodity-like in nature.

In making its investment decisions, the Investment Adviser has adopted the approach of New Mountain Capital, which is based on three primary investment principles:

B.Emphasis on strong downside protection and strict risk controls; and

C.Continued search for superior risk adjusted returns, combined with timely, intelligent exits and outstanding return performance.

Experienced Management Team and Established Platform

The Investment Adviser’s team members have extensive experience in the leveraged lending space. Steven B. Klinsky, New Mountain Capital’s Founder, Chief Executive Officer and Managing Director and Chairman of our board of directors, was a general partner of Forstmann Little & Co., a manager of debt and equity funds totaling multiple billions of dollars in the 1980s and 1990s. He was also a co-founder of Goldman, Sachs & Co. LLC’s Leverage Buyout Group in the period from 1981 to 1984. Robert A. Hamwee, our Vice Chairman of the board of directors and Senior Advisor of New Mountain Capital, was formerly President of GSC Group, Inc. (“GSC”), where he was the portfolio manager of GSC’s distressed debt funds and led the development of GSC’s CLOs. John R. Kline, our President and Chief Executive Officer and Managing Director of New Mountain Capital, worked at GSC as an investment analyst and trader for GSC’s control distressed and corporate credit funds and at Goldman, Sachs & Co. LLC in the Credit Risk Management and Advisory Group. Laura C. Holson, our Chief Operating Officer and Managing Director of New Mountain Capital, joined New Mountain in 2009 as a private equity investment professional and focused on the credit business starting in 2011. She also served as Head of Capital Markets from 2017 to 2021, where she managed the Firm’s financing activities and relationships across its various product lines.

Significant Sourcing Capabilities and Relationships

sectors that were first identified and reviewed in connection with New Mountain Capital’s private equity efforts, and the majority of our current pipeline reflects this as well. Furthermore, the Investment Adviser’s investment professionals have deep and longstanding relationships in both the private equity sponsor community and the lending/agency community which they have and will continue to utilize to generate investment opportunities.

Risk Management through Various Cycles

New Mountain Capital has emphasized tight control of risk since its inception. To date, New Mountain Capital has never experienced a private equity portfolio company bankruptcy. The Investment Adviser seeks to emphasize tight control of risk with our investments in several important ways, consistent with New Mountain Capital’s historical approach. In particular, the Investment Adviser:

◦Emphasizes the origination or purchase of debt in what the Investment Adviser believes are defensive growth companies, which are less likely to be dependent on macro-economic cycles;

◦Targets investments in companies that are preeminent market leaders in their own industries, and when possible, investments in companies that have strong management teams whose skills are difficult for competitors to acquire or reproduce; and

◦Targets investments in companies with significant equity value in excess of our debt investments.

Access to Non Mark to Market, Seasoned Leverage Facilities

The amount available under the Holdings Credit Facility and DB Credit Facility are generally not subject to reduction as a result of mark to market fluctuations in our portfolio investments. For a detailed discussion of our credit facilities, see “Item 1 — Financial Statements and Supplementary Data — Note 7. Borrowings” in our most recent Quarterly Report on Form 10-Q.

Market Opportunity

◦Large pool of uninvested private equity capital available for new buyouts. We expect that private equity firms will continue to pursue acquisitions and will seek to leverage their equity investments with mezzanine loans and/or senior loans (including traditional first and second lien, as well as unitranche loans) provided by companies such as ours.

◦The leveraged finance market has a high level of financing needs over the next several years due to significant maturities. We believe that the large dollar volume of loans that need to be refinanced will present attractive opportunities to invest capital in a manner consistent with our stated objectives.

◦Middle market companies continue to face difficulties in accessing the capital markets. We believe opportunities to serve the middle market will continue to exist. While many middle market companies were formerly able to raise funds by issuing high-yield bonds, we believe this approach to financing has become more difficult as institutional investors have sought to invest in larger, more liquid offerings.

◦Increased regulatory scrutiny of banks has reduced middle market lending. We believe that many traditional bank lenders to middle market businesses have either exited or de-emphasized their service and product offerings in the middle market. These traditional lenders have instead focused on lending and providing other services to large corporate clients. We believe this has resulted in fewer key players and the reduced availability of debt capital to the companies we target.

◦Conservative loan to value. As a result of the credit crisis, many lenders are requiring larger equity contributions from financial sponsors. Larger equity contributions create an enhanced margin of safety for lenders because leverage is a lower percentage of the implied enterprise value of the company.

◦Attractive pricing. Reduced access to, and availability of, debt capital typically increases the interest rates, or pricing, of loans for middle market lenders. Recent primary debt transactions in this market often include upfront fees, original issue discount, prepayment protections and, in some cases, warrants to purchase common stock, all of which should enhance the profitability of new loans to lenders.

Operating and Regulatory Structure

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 RIC under Subchapter M of the Code. See “Certain U.S. Federal Income Tax Considerations” in this prospectus. As a RIC, we generally will not be subject to U.S. federal income tax on any net ordinary income or capital gains that we timely distribute to our stockholders as dividends if we meet certain source-of-income, distribution and asset diversification requirements. We intend to distribute to our stockholders substantially all of our annual taxable income except that we may retain certain net capital gains for reinvestment. To the extent we retain any net capital gains for reinvestment, we will be subject to U.S. federal income tax, and possibly U.S. federal excise tax, with respect to such retained amounts.

We have established the following wholly-owned direct and indirect subsidiaries:

◦NMF Holdings and NMFDB, whose assets are used to secure the NMF Holdings’ credit facility and NMFDB’s credit facility, respectively;

◦SBIC I and SBIC II, who have received licenses from the U.S. Small Business Administration (the “SBA”) to operate as small business investment companies (“SBICs”) under Section 301(c) of the Small Business Investment Act of 1958, as amended (the “1958 Act”) and their general partners, SBIC I GP and SBIC II GP, respectively;

◦NMF Ancora Holdings, Inc. (“NMF Ancora”), NMF QID NGL Holdings, Inc. (“NMF QID”), NMF YP Holdings, Inc. (“NMF YP”), NMF Permian Holdings, LLC (“NMF Permian”), NMF HB, Inc. (“NMF HB”), NMF TRM, LLC (“NMF TRM”), NMF Pioneer, Inc. (“NMF Pioneer”) and NMF OEC, Inc. (“NMF OEC”), which are treated as corporations for U.S. federal income tax purposes and are intended to facilitate our compliance with the requirements to be treated as a RIC under the Code by holding equity or equity-like investments in portfolio companies organized as limited liability companies (or other forms of pass-through entities); we consolidate our tax blocker corporations for accounting purposes but the tax blocker corporations are not consolidated for U.S. federal income tax purposes and may incur income tax expense as a result of their ownership of the portfolio companies; and

◦New Mountain Finance Servicing, L.L.C. (“NMF Servicing”), which serves as the administrative agent on certain investment transactions.

NMNLC is a majority-owned consolidated subsidiary of the Company, which acquires commercial real estate properties that are subject to “triple net” leases has elected to be treated, and intends to comply with the requirements to continue to qualify annually, as a real estate investment trust, or REIT, within the meaning of Section 856(a) of the Code.

Market Data

Statistical and market data used in this prospectus has been obtained from governmental and independent industry sources and publications. We have not independently verified the data obtained from these sources, and we cannot assure you of the accuracy or completeness of the data. Forward-looking information obtained from these sources is subject to the same qualifications and the additional uncertainties regarding the other forward-looking statements contained in this prospectus.

THE OFFERING

We may offer, from time to time, our common stock, preferred stock, subscription rights to purchase shares of common stock, debt securities or warrants representing rights to purchase shares of our common stock, preferred stock or debt securities, on terms to be determined at the time of each offering. We will offer our securities at prices and on terms to be set forth in one or more supplements to this prospectus and any related free writing prospectus. The offering price per share of our securities, less any underwriting commissions or discounts, generally will not be less than the NAV per share of our securities at the time of an offering.

However, we may issue securities pursuant to this prospectus at a price per share that is less than our NAV per share (i) in connection with a rights offering to our existing stockholders, (ii) with the prior approval of the majority of our common stockholders or (iii) under such other circumstances as the SEC may permit. Any such issuance of shares of our common stock below NAV may be dilutive to the NAV of our common stock. See “Item 1A — Risk Factors — Risks Relating to Our Securities” in our most recent Annual Report on Form 10-K.

Our securities may be offered directly to one or more purchasers, including to existing stockholders in a rights offering, through agents designated from time to time by us, or to or through underwriters or dealers. The prospectus supplement relating to an offering will identify any agents or underwriters involved in the sale of our securities, and will disclose any applicable purchase price, fee, commission or discount arrangement between us and our agents or underwriters or among our underwriters or the basis upon which such amount may be calculated. See “Plan of Distribution” in this prospectus. We may not sell any of our securities through agents, underwriters or dealers without delivery of this prospectus and a prospectus supplement describing the method and terms of the offering of securities.

Set forth below is additional information regarding offerings of securities pursuant to this prospectus:


Use of Proceeds			Unless otherwise specified in a prospectus supplement, we intend to use the net proceeds from the sale of our securities for new investments in portfolio companies in accordance with our investment objective and strategies described in this prospectus, to temporarily repay indebtedness (which will be subject to reborrowing), to pay our operating expenses and distributions to our stockholders and for general corporate purposes, and other working capital needs. Proceeds not immediately used for new investments or the temporary repayment of debt will be invested in cash, cash equivalents, U.S. government securities and other high-quality investments that mature in one year or less from the date of the investment. These securities may have lower yields than the types of investments we would typically make in accordance with our investment objective and, accordingly, may result in lower distributions, if any, during such period. Each prospectus supplement to this prospectus or free writing prospectus relating to an offering will more fully identify the use of the proceeds from such offering. See “Use of Proceeds” in this prospectus.

Investment Advisory Fees			We pay the Investment Adviser a fee for its services under an investment advisory and management agreement, as amended (the “Investment Management Agreement”) consisting of two components — a base management fee and an incentive fee. Pursuant to Amendment No. 1 to the Investment Management Agreement dated November 1, 2021 (“Amendment No. 1”), the base management fee is calculated at an annual rate of 1.4% of our gross assets, which equals our total assets on the Consolidated Statements of Assets and Liabilities, less cash and cash equivalents. The base management fee is payable quarterly in arrears, and is calculated based on the average value of our gross assets, which equals our total assets, as determined in accordance with GAAP, less cash and cash equivalents at the end of each of the two most recently completed calendar quarters, and appropriately adjusted on a pro rata basis for any equity capital raises or repurchases during the current calendar quarter. To the extent we invest in derivatives, we will use the actual value of the derivatives, as reported on our Consolidated Statements of Assets and Liabilities, for purposes of calculating our base management fee. Effective as of and for the quarter ended March 31, 2021 through the quarter ending December 31, 2024, the Investment Adviser has entered into a fee waiver agreement (the “Fee Waiver Agreement”), amended on August 7, 2023, pursuant to which the Investment Adviser will waive base management fees in order to reach a target base management fee of 1.25% on gross assets (the “Reduced Base Management Fee”). The Fee Waiver Agreement was most recently extended for a period of one year through the quarter ending December 31, 2024 by the Investment Adviser on August 7, 2023.
			The incentive fee consists of two parts. The first part is calculated and payable quarterly in arrears and equals 20.0% of our “Pre-Incentive Fee Net Investment Income” for the immediately preceding quarter, subject to a “preferred return”, or “hurdle”, and a “catch-up” feature each as described in the Investment Management Agreement. The second part will be determined and payable in arrears as of the end of each calendar year (or upon termination of the Investment Management Agreement) and will equal 20.0% of our “Realized Capital Gains”, if any, on a cumulative basis from inception through the end of the year, computed net of “Realized Capital Losses” and “Unrealized Capital Depreciation” on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fee each as described in the Investment Management Agreement. The Investment Adviser cannot recoup management or incentive fees that the Investment Adviser has previously waived. See “Item 1 — Business — Investment Management Agreement” in our most recent Annual Report on Form 10-K.


Administrator			The Administrator serves as our administrator and arranges our office space and provides us with office equipment and administrative services. The Administrator performs, or oversees the performance of, our financial records, prepares reports to our stockholders and reports filed by us with the SEC, monitors the payment of our expenses, and oversees the performance of administrative and professional services rendered to us by others. We reimburse the Administrator for our allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations to us under an administration agreement, as amended and restated (the “Administration Agreement”). The Administrator cannot recoup any expenses that the Administrator has previously waived. See “Item 1 — Financial Statements and Supplementary Data — Note 5. Agreements” in our most recent Quarterly Report on Form 10-Q.

Distributions			We intend to pay quarterly distributions to our stockholders out of assets legally available for distribution. The quarterly distributions, if any, will be determined by our board of directors. The distributions we pay to our stockholders in a year may exceed our taxable income for that year and, accordingly, a portion of such distributions may constitute a return of capital, which is a return of a portion of a stockholder’s original investment in our common stock, for U.S. federal income tax purposes. Generally, a return of capital will reduce an investor’s basis in our stock for U.S. federal income tax purposes. The specific tax characteristics of our distributions will be reported to stockholders after the end of the calendar year. See “Price Range of Common Stock and Distributions” in this prospectus.

Taxation of NMFC			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 RIC under Subchapter M of the Code. As a RIC, we generally will not be subject to U.S. federal income tax on any net ordinary income or capital gains that are timely distributed to our stockholders as distributions. To maintain our RIC tax treatment, we must meet specified source-of-income and asset diversification requirements and distribute annually to our stockholders at least 90.0% of our net ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, if any. See “Price Range of Common Stock and Distributions” and “Certain U.S. Federal Income Tax Considerations” in this prospectus.


Dividend Reinvestment Plan			We have adopted an “opt out” dividend reinvestment plan for our stockholders. As a result, if we declare a distribution, then your cash distributions will be automatically reinvested in additional shares of our common stock, unless you specifically “opt out” of the dividend reinvestment plan so as to receive cash distributions. Stockholders who receive distributions in the form of our common stock will be subject to the same U.S. federal income tax consequences as stockholders who elect to receive their distributions in cash. We will use only newly issued shares to implement the plan if the price at which newly issued shares are to be credited is equal to or greater than 110.0% of the last determined NAV of our shares. We reserve the right to either issue new shares or purchase shares of our common stock in the open market in connection with our implementation of the plan if the price at which newly issued shares are to be credited to stockholders’ accounts does not exceed 110.0% of the last determined NAV of the shares. See “Dividend Reinvestment Plan” in this prospectus.

Trading at a Discount			Shares of closed-end investment companies frequently trade at a discount to their NAV. The possibility that our common stock may trade at a discount to our NAV per share is separate and distinct from the risk that our NAV per share may decline. We cannot predict whether our common stock will trade above, at or below NAV.

License Agreement			We have entered into a royalty-free license agreement with New Mountain Capital, pursuant to which New Mountain Capital has agreed to grant us a non-exclusive license to use the names “New Mountain” and “New Mountain Finance”, as well as the NMF logo. See “Item 8 — Financial Statements and Supplementary Data — Note 6. Related Parties” in our most recent Annual Report on Form 10-K.

Anti-Takeover Provisions			Our board of directors is divided into three classes of directors serving staggered three-year terms. This structure is intended to provide us with a greater likelihood of continuity of management, which may be necessary for us to realize the full value of our investments. A staggered board of directors also may serve to deter hostile takeovers or proxy contests, as may certain other measures that we may adopt. These measures may delay, defer or prevent a transaction or a change in control that might otherwise be in the best interests of our stockholders. See “Description of Capital Stock — Delaware Law and Certain Certificate of Incorporation and Bylaw Provisions; Anti-Takeover Measures” in this prospectus.


Available Information			We have filed with the SEC a registration statement on Form N-2 together with all amendments and related exhibits under the Securities Act. The registration statement contains additional information about us and the securities being offered by this prospectus. We are required to file annual, quarterly and current reports, proxy statements and other information with the SEC under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This information is also available free of charge by contacting us at New Mountain Finance Corporation, 1633 Broadway, 48th Floor, New York, New York 10019, by telephone at (212) 720-0300, or on our website at www.newmountainfinance.com. Information contained on our website or on the SEC’s website about us is not incorporated into this prospectus and you should not consider information contained on our website or on the SEC’s website to be part of this prospectus.

Incorporation of certain information by reference			This prospectus is part of a registration statement that we have filed with the SEC. We may “incorporate by reference” the information that we file with the SEC, which means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is considered to comprise a part of this prospectus from the date we file that information. Any reports filed by us with the SEC subsequent to the date of this prospectus until we have sold all of the securities offered by this prospectus or the offering is otherwise terminated will automatically update and, where applicable, supersede any information contained in this prospectus or incorporated by reference in this prospectus. See “Incorporation of Certain Information by Reference” in this prospectus.

FEES AND EXPENSES

The following table is intended to assist you in understanding the costs and expenses that you will bear directly or indirectly. We caution you that some of the percentages indicated in the table below are estimates and may vary. Actual costs and expenses incurred by investors in shares of our common stock may be greater than the percentage estimates in the table below. Except where the context suggests otherwise, whenever this prospectus contains a reference to fees or expenses paid by “you”, “NMFC”, or “us” or that “we”, “NMFC”, or the “Company” will pay fees or expenses, we will pay such fees and expenses out of our net assets and, consequently, you will indirectly bear such fees or expenses as an investor in us. However, you will not be required to deliver any money or otherwise bear personal liability or responsibility for such fees or expenses.

__________________

(1)In the event that the securities to which this prospectus relates are sold to or through underwriters, a corresponding prospectus supplement will disclose the applicable sales load.

(2)The prospectus supplement corresponding to each offering will disclose the applicable estimated amount of offering expenses of the offering and the offering expenses borne by us as a percentage of the offering price.

(3)If a participant elects by written notice to the plan administrator to have the plan administrator sell part or all of the shares held by the plan administrator in the participant’s account and remit the proceeds to the participant, the plan administrator is authorized to deduct a $15.00 transaction fee plus a $0.10 per share brokerage commission from the proceeds. The expenses of the dividend reinvestment plan are included in “other expenses.” The plan administrator’s fees will be paid by us. There will be no brokerage charges or other charges to stockholders who participate in the plan. For additional information, see “Dividend Reinvestment Plan” in this prospectus.

(4)The base management fee pursuant to Amendment No. 1 to the Investment Management Agreement is based on an annual rate of 1.4% of our average gross assets for the two most recent quarters, which equals our total assets on the Consolidated Statements of Assets and Liabilities, less cash and cash equivalents. We may, from time to time, invest in derivatives. To the extent we invest in derivatives, we use the actual value of the derivatives, as reported on our Consolidated Statements of Assets and Liabilities, for purposes of calculating our base management fee. The base management fee reflected in the table above is based on the three months ended March 31, 2024 and is calculated without deducting any management fees waived.

(5)Assumes that annual incentive fees earned by the Investment Adviser remain consistent with the gross incentive fees earned by the Investment Adviser during the three months ended March 31, 2024 and calculated without deducting any incentive fees waived. For the three months ended March 31, 2024, no incentive fees were waived by the Investment Adviser. The Investment Adviser cannot recoup incentive fees that the Investment Adviser has previously waived. As of March 31, 2024, we did not have a capital gains incentive fee accrual. As we cannot predict whether we will meet the thresholds for incentive fees under the Investment Management Agreement, the incentive fees paid in subsequent periods, if any, may be substantially different than the fees incurred during the three months ended March 31, 2024. For more detailed information about the incentive fee calculations, see “Item 1 — Business — Investment Management Agreement” in our most recent Annual Report on Form 10-K.

(6)We may borrow funds from time to time to make investments to the extent we determine that additional capital would allow us to take advantage of additional investment opportunities or if the economic situation is otherwise conducive to doing so. The costs associated with these borrowings are indirectly borne by our stockholders. As of March 31, 2024, we had $690.0 million in aggregate principal amount outstanding of the Unsecured Notes, $300.0 million in SBA-guaranteed debentures outstanding, $291.6 million outstanding under the Holdings Credit Facility, $260.0 million in aggregate principal amount outstanding of the 2022 Convertible Notes, $182.0 million outstanding under the DB Credit Facility, $47.6 million under the NMFC Credit Facility, which included £22.9 million denominated in GBP and €17.4 million denominated in EUR that has been converted to U.S. dollars, $2.9 million outstanding under the NMNLC Credit Facility II, and $0 outstanding under the Unsecured Management Company Revolver. For purposes of this calculation, we have assumed the March 31, 2024 amounts outstanding under the Unsecured Notes, SBA-guaranteed debentures, Holdings Credit Facility, 2022 Convertible

Notes, DB Credit Facility, NMFC Credit Facility and NMNLC Credit Facility II, and have computed interest expense using an assumed interest rate of 6.1% for the Unsecured Notes, 2.7% for the SBA-guaranteed debentures, 7.8% for the Holdings Credit Facility, 7.5% for the 2022 Convertible Notes, 8.1% for the DB Credit Facility, 6.8% for the NMFC Credit Facility and 7.6% for the NMNLC Credit Facility II, which were the rates payable as of March 31, 2024. See Item 1 — Financial Statements — Note 7. Borrowings in our most recent Quarterly Report on Form 10-Q.

(7)“Other expenses” include our overhead expenses, including payments by us under the Administration Agreement based on the allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations to us under the Administration Agreement. Pursuant to the Administration Agreement, 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. However, it is expected that the Administrator will continue to support part of our expense burden in the near future and may decide to not calculate and charge through certain overhead related amounts as well as continue to cover some of the indirect costs. The Administrator cannot recoup any expenses that the Administrator has previously waived. This expense ratio is calculated without deducting any expenses waived or reimbursed by the Administrator. For the three months ended March 31, 2024, the indirect administrative expenses that our Administrator did not waive of approximately $0.6 million represented approximately 0.02% of our gross assets. See “Item 1 — Financial Statements and Supplementary Data — Note 5. Agreements” in our most recent Quarterly Report on Form 10-Q.

(8)The holders of shares of our common stock indirectly bear the expenses of our investment in NMFC Senior Loan Program III (“SLP III”) and NMFC Senior Loan Program IV, LLC (“SLP IV”). As SLP III and SLP IV are structured as private joint ventures, no management fees are paid by SLP III or SLP IV. Future expenses for SLP III and SLP IV may be substantially higher or lower because certain expenses may fluctuate over time.

(9)The holders of shares of our common stock indirectly bear the cost associated with our annual expenses.

(10)Effective as of and for the quarter ended March 31, 2021 through the quarter ending December 31, 2024, the Investment Adviser entered into the Fee Waiver Agreement pursuant to which the Investment Adviser will waive base management fees in order to reach the Reduced Base Management fee. The Investment Adviser cannot recoup management fees that the Investment Adviser has previously waived. The base management fee waiver reflected in the table above is based on the base management fees waived during the three months ended March 31, 2024. See “Item 1 — Notes to the Consolidated Financial Statements — Note 5. Agreements — Investment Management Agreement” in our most recent Quarterly Report on Form 10-Q.

Example

The following example, required by the SEC, demonstrates the projected dollar amount of total cumulative expenses that would be incurred over various periods with respect to a hypothetical investment in our common stock. In calculating the following expense amounts, we have assumed that our borrowings and annual operating expenses would remain at the levels set forth in the table above. In the event that shares to which this prospectus relates are sold to or through underwriters, a corresponding prospectus supplement will restate this example to reflect the applicable sales load and offering expenses. See footnote 6 above for additional information regarding certain assumptions regarding our level of leverage.


	1 Year		3 Years		5 Years		10 Years
You would pay the following expenses on a $1,000 investment, assuming a 5.0% annual return without realization of any capital gains	$	155	$	419	$	624	$	964

The example should not be considered a representation of future expenses, and actual expenses may be greater or less than those shown.

While the example assumes, as required by the applicable rules of the SEC, a 5.0% annual return, our performance will vary and may result in a return greater or less than 5.0%. The incentive fee under the Investment Management Agreement, which, assuming a 5.0% annual return, would either not be payable or would have an insignificant impact on the expense amounts shown above, is not included in the above example. The above illustration assumes that we will not realize any capital gains (computed net of all realized capital losses and unrealized capital depreciation) in any of the indicated time periods. If we achieve sufficient returns on our investments, including through the realization of capital gains, to trigger an incentive fee of a material amount, our expenses and returns to our investors would be higher. For example, if we assumed that we received our 5.0% annual return completely in the form of net realized capital gains on our investments, computed net of all cumulative

unrealized depreciation on our investments, the projected dollar amount of total cumulative expenses set forth in the above illustration would be as follows:


	1 Year		3 Years		5 Years		10 Years
You would pay the following expenses on a $1,000 investment, assuming a 5.0% annual return completely in the form of net realized capital gains	$	164	$	437	$	647	$	983

The example assumes no sales load. In addition, while the examples assume reinvestment of all distributions at NAV, participants in our dividend reinvestment plan will receive a number of shares of our common stock determined by dividing the total dollar amount of the distribution payable to a participant by the market price per share of our common stock at the close of trading on the dividend payment date. The market price per share of our common stock may be at, above or below NAV. See “Dividend Reinvestment Plan” in this prospectus for additional information regarding the dividend reinvestment plan.

FINANCIAL HIGHLIGHTS

The financial data as of and for each of the ten years ended December 31, 2023 through December 31, 2014 is set forth in Part II, Item 5 of our most recent Annual Report on Form 10-K and the information in Note 13 to our consolidated financial statements appearing in our most recent Annual Report on Form 10-K is incorporated by reference herein. The financial data has been audited by Deloitte & Touche LLP, an independent registered public accounting firm whose reports thereon are incorporated by reference in this prospectus. A copy of our Annual Report on Form 10-K filed with the SEC may be obtained from www.sec.gov or upon request. You should read these financial highlights in conjunction with our consolidated financial statements and notes thereto and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” incorporated by reference into this prospectus, any documents incorporated by reference in this prospectus or the accompanying prospectus supplement, or our Annual Reports on Form 10-K filed with the SEC.

RISK FACTORS

Investing in our securities involves a high degree of risk. In addition to the other information contained in this prospectus and any accompanying prospectus supplement, you should consider carefully the following information before making an investment in our securities. Before deciding whether to invest in our securities, you should carefully consider the risks and uncertainties described in the section titled “Risk Factors” in the applicable prospectus supplement and any related free writing prospectus, and discussed in the section titled “Item 1A. Risk Factors” in our most recent Annual Report on Form 10-K, the section titled “Item 1A. Risk Factors” in our most recent Quarterly Report on Form 10-Q, and any subsequent filings we have made with the SEC that are incorporated by reference into this prospectus, together with other information in this prospectus, the documents incorporated by reference in this prospectus or any prospectus supplement, and any free writing prospectus that we may authorize for use in connection with this offering. The risks and uncertainties described in these documents could materially adversely affect our business, financial condition, and results of operations. The risks described in these documents are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, reputation, financial condition, results of operations, revenue, and future prospects could be seriously harmed. This could cause our NAV and the trading price of our securities to decline, resulting in a loss of all or part of your investment. Please also read carefully the section titled “Cautionary Statement Regarding Forward-Looking Statements.”

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, including the documents that we incorporate by reference herein, contains, and any applicable prospectus supplement or free writing prospectus, including the documents we incorporate by reference therein, may contain forward-looking statements that involve substantial risks and uncertainties, including statements regarding our future financial condition, business strategy, and plans and objectives of management for future operations. All statements other than statements of historical facts, including statements regarding our future results of operations or financial condition, business strategy and plans, and objectives of management for future operations, are forward-looking statements. Any such forward-looking statements may involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from future results, performance or achievements expressed or implied by any forward-looking statements. These forward-looking statements are not historical facts, but rather are based on current expectations, estimates and projections about us, our current and prospective portfolio investments, our industry, our beliefs, and our assumptions.

Words such as “anticipate”, “believe”, “continue”, “could”, “estimate”, “expect”, “intend”, “may”, “plan”, “potential”, “project”, “seek”, “should”, “target”, “will”, “would” or variations of these words and similar expressions are intended to identify forward-looking statements. The forward- looking statements contained in this prospectus, any applicable prospectus supplement or free writing prospectus, including the documents we incorporate by reference therein, involve risks and uncertainties, including statements as to:

◦the impact of a protracted decline in the liquidity of credit markets;

◦the general economy, including interest and inflation rates, on the industries in which we invest;

◦the impact of interest rate volatility, including the replacement of LIBOR with alternative reference rates and elevated interest rates, on our business and our portfolio companies;

◦our future operating results, our business prospects, the adequacy of our cash resources and working capital;

◦the ability of our portfolio companies to achieve their objectives;

◦our ability to make investments consistent with our investment objectives, including with respect to the size, nature and terms of our investments;

◦the ability of the Investment Adviser or its affiliates to attract and retain highly talented professionals;

◦actual and potential conflicts of interest with the Investment Adviser and New Mountain Capital;

These statements are not guarantees of future performance and are subject to risks, uncertainties, and other factors, some of which are beyond our control and difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward- looking statements, including without limitation:

◦an economic downturn could impair our portfolio companies’ ability to continue to operate, which could lead to the loss of some or all of our investments in such portfolio companies;

◦a contraction of available credit and/or an inability to access the equity markets could impair our lending and investment activities;

◦interest rate volatility could adversely affect our results, particularly if we elect to use leverage as part of our investment strategy;

◦currency fluctuations could adversely affect the results of our investments in foreign companies, particularly to the extent that we receive payments denominated in foreign currency rather than U.S. dollars; and

◦the risks, uncertainties and other factors we identify in the section entitled “Risk Factors” in this prospectus, and in Part I, Item 1A of our most recent Annual Report on Form 10-K, in Part II, Item 1A of our most recent Quarterly Report on Form 10-Q, and those discussed in other documents we file with the SEC.

Although we believe that the assumptions on which these forward-looking statements are based are reasonable, any of those assumptions could prove to be inaccurate, and as a result, the forward-looking statements based on those assumptions also could be inaccurate. Important assumptions include our ability to originate new loans and investments, certain margins and levels of profitability and the availability of additional capital. In light of these and other uncertainties, the inclusion of a projection or forward-looking statement in this prospectus, any applicable prospectus supplement or free writing prospectus, including the documents we incorporate by reference, should not be regarded as a representation by us that our plans and objectives will be achieved.

These risks and uncertainties include those described or identified in “Risk Factors” in Part I, Item 1A of our most recent Annual Report on Form 10-K, in Part II, Item 1A of our most recent Quarterly Report on Form 10-Q, and elsewhere in this prospectus, any applicable prospectus supplement or free writing prospectus, including the documents we incorporate by reference. You should not place undue reliance on these forward-looking statements, which are based on information available to us as of the applicable date of this prospectus, any applicable prospectus supplement or free writing prospectus, including any documents incorporated by reference, and while we believe such information forms, or will form, a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely on these statements.

USE OF PROCEEDS

Unless otherwise specified in a prospectus supplement, we intend to use the net proceeds from the sale of our securities pursuant to this prospectus for new investments in portfolio companies in accordance with our investment objective and strategies described in this prospectus, to temporarily repay indebtedness (which will be subject to reborrowing), to pay our operating expenses, to pay distributions to our stockholders and for general corporate purposes, and other working capital needs. We are continuously identifying, reviewing and, to the extent consistent with our investment objective, funding new investments. As a result, we typically raise capital as we deem appropriate to fund such new investments. The applicable prospectus supplement or a free writing prospectus that we have authorized for use relating to an offering will more fully identify the use of the proceeds from such offering.

We estimate that it will take less than six months for us to substantially invest the net proceeds of any offering made pursuant to this prospectus, depending on the availability of attractive opportunities, market conditions and the amount raised. However, we can offer no assurance that we will be able to achieve this goal.

Proceeds not immediately used for new investments or the temporary repayment of debt will be invested primarily in cash, cash equivalents, U.S. government securities and other high-quality investments that mature in one year or less from the date of investment. These securities may have lower yields than the types of investments we would typically make in accordance with our investment objective and, accordingly, may result in lower distributions, if any, during such period.

•Not determinable at the time of filing.

On June 24, 2024, the last reported sales price of our common stock was $12.23 per share. As of June 24, 2024, we had twelve stockholders of record and one beneficial owner whose shares are held in the names of brokers, dealers, funds, trusts and clearing agencies.

Shares of BDCs may trade at a market price that is less than the value of the net assets attributable to those shares. The possibility that our shares of common stock will trade at a discount from NAV or at premiums that are unsustainable over the long term are separate and distinct from the risk that our NAV will decrease. Since our initial public offering on May 19, 2011, our shares of common stock have traded at times at both a discount and a premium to the net assets attributable to those shares. As of June 24, 2024, our shares of common stock traded at a discount of approximately 4.2% of the NAV attributable to those shares as of March 31, 2024. It is not possible to predict whether the shares offered hereby will trade at, above, or below NAV.

We intend to pay quarterly distributions to our stockholders in amounts sufficient to maintain our status as a RIC. We intend to distribute approximately our entire 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. The distributions we pay to our stockholders in a year may exceed our taxable income for that year and, accordingly, a portion of such distributions may constitute a return of capital, which is a return of a portion of a stockholder’s original investment in our common stock, for U.S. federal income tax purposes. Generally, a return of capital will reduce an investor’s adjusted tax basis in our stock for U.S. federal income tax purposes. The specific tax characteristics of our distributions will be reported to stockholders after the end of the calendar year.

We maintain an “opt out” dividend reinvestment plan on behalf of our stockholders, pursuant to which each of our stockholders’ cash distributions will be automatically reinvested in additional shares of our common stock, unless the stockholder elects to receive cash.

We apply the following in implementing the dividend reinvestment plan. If the price at which newly issued shares are to be credited to stockholders’ accounts is equal to or greater than 110.0% of the last determined NAV of the shares, we will use only newly issued shares to implement the dividend reinvestment plan. Under such circumstances, the number of shares to be issued to a stockholder is determined by dividing the total dollar amount of the distribution payable to such stockholder by the market price per share of our common stock on the NASDAQ on the distribution payment date. Market price per share on that date will be the closing price for such shares on the NASDAQ or, if no sale is reported for such day, the average of their electronically reported bid and ask prices.

If the price at which newly issued shares are to be credited to stockholders’ accounts is less than 110.0% of the last determined NAV of the shares, we will either issue new shares or instruct the plan administrator to purchase shares in the open market to satisfy the additional shares required. Shares purchased in open market transactions by the plan administrator will be allocated to a stockholder based on the average purchase price, excluding any brokerage charges or other charges, of all shares of common stock purchased in the open market. The number of shares of our common stock to be outstanding after giving effect to payment of the distribution cannot be established until the value per share at which additional shares will be issued has been determined and elections of our stockholders have been tabulated.

The following table reflects the cash distributions, including dividends and returns of capital, if any, per share that have been declared by our board of directors for the two most recent fiscal years and the current fiscal year to date:
