PRELIMINARY PROSPECTUS SUPPLEMENT
(to Prospectus dated April 29, 2019)

8,000,000 Shares

New Mountain Finance Corporation

Common Stock


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 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, including first and second lien debt, notes, bonds and mezzanine securities. Our first lien debt may include traditional first lien senior secured loans or unitranche loans. Unitranche loans combine characteristics of traditional first lien senior secured loans as well as second lien and subordinated loans. Unitranche loans will expose us to the risks associated with second lien and subordinated loans to the extent we invest in the "last out" tranche. 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) sustainable secular growth drivers, (ii) high barriers to competitive entry, (iii) high free cash flow after capital expenditure and working capital needs, (iv) high returns on assets and (v) niche market dominance.

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 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 are offering for sale 8,000,000 shares of our common stock. Certain of our officers and interested directors listed in the "Underwriting" section of this prospectus supplement have submitted a non-binding indication of interest to purchase an aggregate of 400,000 shares in this offering at the public offering price. We have granted the underwriters a 30-day option to purchase up to 1,200,000 additional shares of our common stock at the public offering price, less underwriting discounts and commissions.

Our common stock is listed on the New York Stock Exchange under the symbol "NMFC". On October 21, 2019, the last reported sales price on the New York Stock Exchange for our common stock was $13.51 per share, and the net asset value per share of our common stock on June 30, 2019 (the last date prior to the date of this prospectus supplement on which we determined our net asset value per share) was $13.41.

An investment in our common stock is very risky and highly speculative. Shares of closed-end investment companies, including business development companies, frequently trade at a discount to their net asset value. In addition, the companies in which we invest in are subject to special risks. See "Risk Factors" beginning on page S-25 of this prospectus supplement and beginning on page 22 of the accompanying prospectus to read about factors you should consider, including the risk of leverage, before investing in our common stock.

This prospectus supplement and the accompanying prospectus contain important information about us that a prospective investor should know before investing in our common stock. Please read this prospectus supplement and the accompanying prospectus before investing and keep it for future reference. We file annual, quarterly and current reports, proxy statements and other information with the United States Securities and Exchange Commission (http://www.sec.gov), which are available free of charge by contacting us by mail at 787 Seventh Avenue, 48th Floor, New York, New York 10019 or on our website at http://www.newmountainfinance.com. Information contained on our website is not incorporated by reference into this prospectus supplement and the accompanying prospectus, and you should not consider that information to be part of this prospectus supplement and the accompanying prospectus.


Neither the United States Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities, or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

As per an arrangement between the underwriters and certain of our officers and interested directors, the underwriters will not receive the sales load on the 400,000 shares expected to be purchased by such officers and interested directors, which decreases the total sales load received by the underwriters from us by approximately $             and increases proceeds to us by approximately $             .

The underwriters expect to deliver the shares against payment in New York, New York on or about                 , 2019.

Table of Contents

          For the periods prior to and as of December 31, 2013, all financial information provided in this prospectus supplement and accompanying prospectus reflect our organizational structure prior to the restructuring on May 8, 2014 described in "Note 1. Formation and Business Purpose — Restructuring" to our consolidated financial statements included in the accompanying prospectus, where NMF Holdings functioned as the operating company.

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

S-2


Table of Contents

Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). NMFC is also registered as an investment adviser under the Investment Advisers Act of 1940, as amended (the "Advisers Act").

          The Investment Adviser is a wholly-owned subsidiary of New Mountain Capital. New Mountain Capital is a firm with a track record of investing in the middle market. New Mountain Capital focuses on investing in defensive growth companies across its private equity, public equity and credit investment vehicles. 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, a wholly-owned subsidiary of New Mountain Capital, 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 debt securities at all levels of the capital structure, including first and second lien debt, notes, bonds and mezzanine securities. The first lien debt may include traditional first lien senior secured loans or unitranche loans. Unitranche loans combine characteristics of traditional first lien senior secured loans as well as second lien and subordinated loans. Unitranche loans will expose us to the risks associated with second lien and subordinated loans to the extent we invest in the "last out" tranche. 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) sustainable secular growth drivers, (ii) high barriers to competitive entry, (iii) high free cash flow after capital expenditure and working capital needs, (iv) high returns on assets and (v) niche market dominance. Similar to us, SBIC I's and SBIC II's investment objectives are to generate current income and capital appreciation under our investment criteria. However, SBIC I's and SBIC II's investments must be in SBA eligible small businesses. Our portfolio may be concentrated in a limited number of industries. As of June 30, 2019, our top five industry concentrations were business services, software, healthcare services, education and investment funds (which includes our investments in our joint ventures).

          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 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.

          As of June 30, 2019, our net asset value was $1,080.9 million and our portfolio had a fair value of approximately $2,643.1 million in 101 portfolio companies, with a weighted average yield to maturity at cost for income producing investments ("YTM at Cost") of approximately 9.4% and a weighted average yield to maturity at cost for all investments ("YTM at Cost for Investments") of approximately 9.4%. The 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. The YTM at Cost for Investments calculation assumes that all investments, including secured collateralized agreements, are purchased as 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 uses the London Interbank Offered Rate ("LIBOR") curves at each quarter's end date. The actual yield to maturity may be higher or lower

due to the future selection of the LIBOR contracts by the individual companies in our portfolio or other factors.

Recent Developments

Common Stock Offering

          On July 11, 2019, we completed a public offering of 6,900,000 shares of our common stock at a public offering price of $13.68 per share. Our Investment Adviser paid a $0.39 per share portion of the $0.42 per share underwriters' sales load such that we received net proceeds of $13.65 per share in this offering. All payments made by our Investment Adviser are not subject to reimbursement by us. We received total net proceeds of approximately $94.2 million in connection with this offering.

Distribution Announcement

          On August 1, 2019, our board of directors declared a third quarter 2019 distribution of $0.34 per share which was paid on September 27, 2019 to holders of record as of September 13, 2019.

Credit Facility Amendments

          On August 12, 2019, we entered into Amendment No. 3 to the Loan Financing and Servicing Agreement (the "Third Amendment"), which amended the DB Credit Facility, by and among the Company, as the equityholder and the servicer, NMFDB, as the borrower, Deutsche Bank AG, New York Branch ("DBNY"), as the facility agent, U.S. Bank National Association, as the collateral agent and collateral custodian, and DBNY as agent and lender, and each of the other agents and lenders from time to time party thereto.

          Pursuant to the Third Amendment, among other things, (i) DBNY assigned portions of its commitments under the DB Credit Facility to KeyBank National Association ("KeyBank") and Customers Bank ("Customers"), and KeyBank and Customers upsized their respective commitments under the DB Credit Facility, such that the aggregate commitments under, and maximum facility amount of, the DB Credit Facility increased from $150.0 million to $210.0 million, and (ii) certain other customary modifications were made to the DB Credit Facility, as set forth in Appendix A to the Third Amendment.

          The DB Credit Facility continues to have a revolving period ending on December 14, 2021 and will still mature on December 14, 2023.

          On August 27, 2019, we entered into a Commitment Increase Agreement (the "Commitment Agreement") related to the NMFC Credit Facility. The Commitment Agreement increases the total commitments under the NMFC Credit Facility from $135.0 million to $138.5 million from existing lenders in accordance with the accordion feature of the NMFC Credit Facility.

          On September 6, 2019, we entered into (i) certain Joinder Supplements (the "Joinders") to add Old Second National Bank and Raymond James Bank, N.A., each as new lenders under the Holdings Credit Facility, (ii) a Facility Increase Agreement (the "Facility Increase Agreement") with State Street Bank and Trust Company to increase its commitment under the Holdings Credit Facility and (iii) Incremental Commitment Supplement (the "Commitment Supplement") with CIT Bank, N.A. to increase its commitment under the Holdings Credit Facility. After giving effect to the Joinders, the Facility Increase Agreement and the Commitment Supplement, the aggregate commitments of the lenders under the Holdings Credit Facility equals $800.0 million. The Holdings Credit Facility continues to have a revolving period ending on October 24, 2020, and will still mature on October 24, 2022.

          On October 16, 2019, we entered into a Joinder Agreement pursuant to which Hitachi Capital America Corp. was added as a lender under the DB Credit Facility for an aggregate commitment of $20.0 million thereby increasing the aggregate commitments under the DB Credit Facility from $210.0 million to $230.0 million.

Co-investment Order

          On October 8, 2019, the SEC issued an exemptive order (the "New Order") permitting us and certain of our affiliates to co-invest together in portfolio companies subject to certain conditions included therein. The New Order supersedes our existing co-investment exemptive order, which was granted by the SEC on December 18, 2017, and expands on our ability to co-invest with certain affiliates.

New Director

          On September 13, 2019, our Board of Directors appointed Daniel B. Hébert as a Class III director with a term that expires at the Company's 2020 annual meeting of stockholders. Additionally, Mr. Hébert was appointed to the Company's Audit Committee, Valuation Committee, Compensation Committee and Nominating and Corporate Governance Committee. Mr. Hébert was previously a member of the Company's Board of Directors from August 2011 until March 2012.

          Since May 2017, Mr. Hébert has been the Co-Founder and Chief Operating Officer of Bernstein Equity Partners LLC, an investment banking firm. From October 2013 until April 2017, Mr. Hébert was a Managing Director at Sandler & O'Neill, an investment banking firm. He served as a Partner and Managing Director at North Sea Partners LLC, an investment banking firm, from 2011 until September 2013. Mr. Hébert received his B.A. from Acadia University and his M.B.A. from the Richard Ivey School of Business. Mr. Hébert brings his experience in investment banking to our board of directors. This background positions Mr. Hébert well to serve as our director.

          Mr. Hébert is not an "interested person" of the Company as such term is defined under the 1940 Act. Therefore, the Company's Board of Directors now consists of a majority of non-interested persons, which requirement was suspended for 90 days from June 17, 2019, in accordance with Section 56(b) of the 1940 Act, due to the untimely death of Mr. Kurt Wolfgruber, our former director.

Preliminary Estimates of Net Asset Value and Net Investment Income

          Set forth below is a preliminary estimate of our net asset value per share as of September 30, 2019 and a preliminary estimate of our net investment income per share range for the three months ended September 30, 2019. The following estimates are not a comprehensive statement of our financial condition or results for the period ended September 30, 2019. We advise you that our actual results for the three months ended September 30, 2019 may differ materially from these estimates, which are given only as of the date of this prospectus supplement, as a result of the completion of our financial closing procedures, final adjustments and other developments, including changes in interest rates, changes in the businesses to whom we have made loans or market and industry fluctuations, which may arise between now and the time that our financial results for the three months ended September 30, 2019 are finalized. This information is inherently uncertain.

          As of the date of this prospectus supplement, we estimate that our net asset value per share as of September 30, 2019 was approximately $13.30 to $13.40.

          As of the date of this prospectus supplement, we currently expect that our net investment income per share was between $0.35 and $0.36 for the three months ended September 30, 2019.

          The preliminary financial estimates provided herein have been prepared by, and are the responsibility of, management. Neither Deloitte & Touche LLP, our independent registered public accounting firm, nor any other independent accountants have audited, reviewed, compiled, or performed any procedures with respect to the accompanying preliminary financial data. Accordingly, Deloitte & Touche LLP does not express an opinion or any form of assurance with respect thereto and assumes no responsibility for, and disclaims any association with, this information.

The Investment Adviser

          The Investment Adviser, a wholly-owned subsidiary of New Mountain Capital, 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. As of June 30, 2019, the Investment Adviser was supported by over 150 employees and senior advisors of New Mountain Capital.

          The Investment Adviser is managed by a five 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, Adam B. Weinstein and John R. Kline. The fifth 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 2018 to July 2019. Beginning in August 2019, Lars O. Johansson was appointed to the Investment Committee for a one year term. 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, federal 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:

S-6


Table of Contents

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 Chief Executive Officer and Managing Director 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 Operating 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.

          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 significant 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:

Access to Non Mark to Market, Seasoned Leverage Facility

          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. None of our credit facilities, with the exception of the NMNLC Credit Facility, which matures in September 2020, mature prior to June 2022. For a detailed discussion of our credit facilities, see "Management's Discussion and Analysis of Financial Conditions and Results of Operations — Liquidity and Capital Resources" in this prospectus supplement.

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.

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% 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. See "Regulation — Senior Securities" in the accompanying prospectus.

          We have elected to be treated, and intend to comply with the requirements to continue to qualify annually, as a RIC under Subchapter M of the Code. See "Material U.S. Federal Income Tax Considerations" in the accompanying prospectus. As a RIC, we generally will not be subject to corporate-level U.S. federal income taxes 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.

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

Risks

          An investment in our common stock involves risk, including the risk of leverage and the risk that our operating policies and strategies may change without prior notice to our stockholders or prior stockholder approval. See "Risk Factors" and the other information included in this prospectus supplement and the accompanying prospectus for a discussion of factors you should carefully consider before deciding to invest in our common stock. The value of our assets, as well as the market price of our common stock, will fluctuate. Our investments may be risky, and you may lose all or part of your investment. Investing in us involves other risks, including the following:

OFFERING

Common Stock Offered

  We are offering 8,000,000 shares of our common stock. To the extent that the underwriters sell more than 8,000,000 shares of our common stock, the underwriters have the option to purchase up to an additional 1,200,000 shares of our common stock at the initial public offering price, less the underwriting discounts and commissions (sales load), within 30 days of the date of this prospectus supplement.

Shares of Our Common Stock Currently Outstanding

 

87,568,695 shares.

Shares of Our Common Stock Outstanding After This Offering

 

95,568,695 shares, excluding 1,200,000 shares of common stock issuable pursuant to the option to purchase additional shares granted to the underwriters. This amount does not include any shares which may be issuable upon conversion of existing securities.

Use of Proceeds

 

Our net proceeds from this offering will be approximately $             million, after deducting $             million of sales load and estimated offering expenses of approximately $0.3 million payable by us. In addition, the Investment Adviser has agreed to bear $             million of sales load in connection with this offering, which will not be subject to reimbursement by us. If the underwriters' option to purchase additional shares is exercised in full, our net proceeds from this offering will be approximately $             million, after deducting $             million of sales load and estimated offering expenses of approximately $0.3 million payable by us. In addition, if the underwriters' option to purchase additional shares is exercised in full, the Investment Adviser has agreed to bear $             million of sales load in connection with this offering, which will not be subject to reimbursement by us. Certain of our officers and interested directors listed in the "Underwriting" section of this prospectus supplement have submitted a non-binding indication of interest to purchase an aggregate of 400,000 shares of the common stock in connection with this offering. As per an arrangement with the underwriters, we and the Investment Adviser will not pay and the underwriters will not receive the sales load on the shares that certain of our officers and interested directors expect to purchase in this offering. As a result, the estimated net proceeds to be received by us from this offering set forth above assumes the receipt of $             million with respect to the shares purchased by certain of our officers and interested directors. We intend to use the net proceeds from this offering primarily for new investments in portfolio companies in accordance with our investment objective and strategies described in this prospectus supplement and the accompanying prospectus. We may also use a portion of the net proceeds from the sale of shares of our common stock sold in this offering for other general corporate purposes, including to temporarily repay indebtedness (which will be subject to reborrowing), and other working capital requirements. 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. We expect that it will take up to three months for us to substantially invest the net proceeds of this offering, depending on the availability of attractive opportunities and market conditions. 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 the investment.

S-12


Table of Contents

 

These temporary investments are expected to provide a lower net return than we hope to achieve from our target investments and, accordingly, may result in lower distributions, if any, during such period. See "Use of Proceeds" in this prospectus supplement.

Investment Advisory Fees

 

We pay the Investment Adviser a fee for its services under an investment advisory and management agreement (the "Investment Management Agreement") consisting of two components — a base management fee and an incentive fee. Pursuant to the Investment Management Agreement, the base management fee is calculated at an annual rate of 1.75% of our gross assets, which equals our total assets on the Consolidated Statements of Assets and Liabilities, less (i) the borrowings under the SLF Credit Facility and (ii) 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 accounting principles generally accepted in the United States of America ("GAAP"), less the borrowings under the SLF Credit Facility and 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. We have not invested, and currently do not invest, in derivatives. To the extent we invest in derivatives in the future, 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. Since our IPO, the base management fee calculation has deducted the borrowings under the SLF Credit Facility. The SLF Credit Facility had historically consisted of primarily lower yielding assets at higher advance rates. As part of an amendment to our existing credit facilities with Wells Fargo Bank, National Association, the SLF Credit Facility merged with the Predecessor Holdings Credit Facility and into the Holdings Credit Facility on December 18, 2014. Post credit facility merger and to be consistent with the methodology since our IPO, the Investment Adviser will continue to waive management fees on the leverage associated with those assets held under revolving credit facilities that share the same underlying yield characteristics with investments leveraged under the legacy SLF Credit Facility. 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 Adjusted 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 "Adjusted Realized Capital Gains", if any, on a cumulative basis from inception through the end of the year, computed net of all "Adjusted Realized Capital Losses" and "Adjusted 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 fees that the Investment Adviser has previously waived. See "Investment Management Agreement" in the accompanying prospectus.

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. For the three and six months ended June 30, 2019, approximately $0.7 million and $1.4 million, respectively, of indirect administrative expenses were included in administrative expenses, of which approximately $0.3 million and $0.3 million, respectively, of indirect administrative expenses were waived by the Administrator. As of June 30, 2019, $0.4 million of indirect administrative expenses were included in payable to affiliates. See "Administration Agreement" in the accompanying prospectus.

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 shareholder'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, which will result in a higher tax liability when the stock is sold. 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 supplement and the accompanying prospectus.

Taxation of NMFC

 

We have elected to be treated, 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 pay corporate-level U.S. federal income taxes on any net ordinary income or capital gains that are timely distributed to our stockholders as dividends. 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" in this prospectus supplement and in the accompanying prospectus and "Material U.S. Federal Income Tax Considerations" in the accompanying 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 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 net asset value 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 net asset value of the shares. See "Dividend Reinvestment Plan" in the accompanying prospectus.

Trading at a Discount

 

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

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". See "License Agreement" in the accompanying prospectus.

Leverage

 

We expect to continue to use leverage to make investments. As a result, we may continue to be exposed to the risks of leverage, which include that leverage may be considered a speculative investment technique. The use of leverage magnifies the potential for gain and loss on amounts we invest and therefore, indirectly, increases the risks associated with investing in shares of our common stock. See "Risk Factors" in this prospectus supplement and the accompanying prospectus.

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 the accompanying 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 of 1933, as amended (the "Securities Act"). The registration statement contains additional information about us and the shares of common stock being offered by this prospectus supplement and the accompanying 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 on an as-converted basis. We caution you that some of the percentages indicated in the table below are estimates and may vary. Except where the context suggests otherwise, whenever this prospectus supplement and the accompanying 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.

Represents the sales load to be paid by us with respect to the shares of common stock to be sold by us in this offering for which the calculation is adjusted. Certain of our officers and interested directors have submitted a non-binding indication of interest to purchase an aggregate of 400,000 shares of the common stock in connection with this offering. As per an arrangement with the underwriters, we and the Investment Adviser will not pay and the underwriters will not receive the sales load on the shares that certain of our officers and interested directors expect to purchase in this offering. The Investment Adviser has agreed to bear $             per share, or approximately         % of the offering price, excluding the 400,000 shares that certain of our officers and interested directors expect to purchase in this offering, of the sales load in connection with this offering, which is not reflected in the above table and will not be subject to reimbursement by us. There is no guaranty that there will be any sales of our common stock pursuant to this prospectus supplement or the accompanying prospectus.

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 the accompanying prospectus.

The base management fee under the Investment Management Agreement is based on an annual rate of 1.75% 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 (i) the borrowings under the SLF Credit Facility and (ii) cash and cash equivalents. We have not invested, and currently do not invest, in derivatives. To the extent we invest in derivatives in the future, 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. The base management fee reflected in the table above is based on the six months ended June 30, 2019 and is calculated without deducting any management fees waived. See "Investment Management Agreement" in the accompanying prospectus.

(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 six months ended June 30, 2019 and calculated without deducting any incentive fees waived. As of June 30, 2019, 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 six months ended June 30, 2019. For more detailed information about the incentive fee calculations, see "Investment Management Agreement" in the accompanying prospectus.

(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 June 30, 2019, we had $549.1 million, $135.0 million, $100.0 million, $201.3 million, $453.3 million and $165.0 million of indebtedness outstanding under the Holdings Credit Facility, the NMFC Credit Facility, the DB Credit Facility, the 2018 Convertible Notes, the Unsecured Notes and the SBA-guaranteed debentures, respectively. For purposes of this calculation, we have assumed the June 30, 2019 amounts outstanding under the Holdings Credit Facility, NMFC Credit Facility, DB Credit Facility, 2018 Convertible Notes, Unsecured Notes and SBA-guaranteed debentures, and have computed interest expense using an assumed interest rate of 4.4% for the Holdings Credit Facility, 4.9% for the NMFC Credit Facility, 5.3% for the DB Credit Facility, 5.75% for the 2018 Convertible Notes, 5.26% for the Unsecured Notes and 3.3% for the SBA-guaranteed debentures, which were the rates payable as of June 30, 2019. See "Senior Securities" in this prospectus supplement.

(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. Assuming $0.3 million of expenses waived or reimbursed by the Administrator for the six months ended June 30, 2019, the annual expense ratio after deducting the expenses waived or reimbursed by the Administrator as a percentage of net assets would be 0.67%. For the six months ended June 30, 2019, we reimbursed the Administrator approximately $1.1 million for indirect administrative expenses that our Administrator did not

The holders of shares of our common stock indirectly bear the expenses of our investment in NMFC Senior Loan Program I, LLC ("SLP I"), NMFC Senior Loan Program II, LLC ("SLP II") and NMFC Senior Loan Program III, LLC ("SLP III"). No management fee is charged on our investment in SLP I in connection with the administrative services provided to SLP I. As SLP II and SLP III are structured as private joint ventures, no management fees are paid by SLP II and SLP III. Future expenses for SLP I, SLP II and SLP III may be substantially higher or lower because certain expenses may fluctuate over time.

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

Since our IPO, the base management fee calculation has deducted the borrowings under the SLF Credit Facility. The SLF Credit Facility had historically consisted of primarily lower yielding assets at higher advance rates. As part of an amendment to our existing credit facilities with Wells Fargo Bank, National Association, the SLF Credit Facility merged with the Predecessor Holdings Credit Facility and into the Holdings Credit Facility on December 18, 2014. Post credit facility merger and to be consistent with the methodology since our IPO, the Investment Adviser will continue to waive management fees on the leverage associated with those assets held under revolving credit facilities that share the same underlying yield characteristics with investments leveraged under the legacy SLF Credit Facility. 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 six months ended June 30, 2019. See "Investment Management Agreement" in the accompanying prospectus.


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. See Note 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

  $     $     $     $    

          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:

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

  $     $     $     $    

          The example assumes a sales load borne by us of         %. In addition, while the examples assume reinvestment of all distributions at net asset value, 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 net asset value. See "Dividend Reinvestment Plan" in the accompanying prospectus for additional information regarding the dividend reinvestment plan.

In applying the if-converted method, conversion is not assumed for purposes of computing diluted earnings per share if the effect would be anti-dilutive. For the year ended December 31, 2015, there was anti-dilution. For the six months ended June 30, 2019 and the years ended December 31, 2018, December 31, 2017, December 31, 2016 and December 31, 2014, there was no anti-dilution.

On January 1, 2016, we adopted Accounting Standard Update No. 2015-03, Interest — Imputation of Interest Subtopic 835-30 — Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"). Upon adoption, we revised our presentation of deferred financing costs from an asset to a liability, which is a direct deduction to our debt on the Consolidated Statements of Assets and Liabilities. In addition, as of December 31, 2015 and December 31, 2014, we retrospectively revised our presentation of $14.0 million and $14.1 million, respectively, of deferred financing costs that were previously presented as an asset, which resulted in a decrease to total assets and total liabilities as of December 31, 2015 and December 31, 2014.

(4)
Total return is calculated assuming a purchase of common stock at the opening of the first day of the period and a sale on the closing of the last business day of the respective period ends. Dividends and distributions, if any, are assumed for purposes of this calculation, to be reinvested at prices obtained under our dividend reinvestment plan.

(5)
Total return is calculated assuming a purchase at net asset value on the opening of the first day of the period and a sale at net asset value on the last day of the period. Dividends and distributions, if any, are assumed for purposes of this calculation, to be reinvested at the net asset value on the last day of the respective quarter.

For the year ended December 31, 2014, amounts include our investment activity and the investment activity of the Predecessor Operating Company.

The weighted average YTM at Cost calculation assumes that all investments, including secured collateralized agreements, not on non-accrual are purchased at the adjusted cost on the respective period ends and held until their respective maturities with no prepayments or losses and exited at par at maturity. The 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") curves at each quarter's end date. The actual yield to maturity may be higher or lower due to the future selection of the LIBOR contracts by the individual companies in our portfolio or other factors. Adjusted cost reflects the cost for post-IPO investments in accordance with accounting principles generally accepted in the United States of America ("GAAP") and a stepped up cost basis of pre-IPO investments (assuming a step-up to fair market value occurred on the IPO date).

RISK FACTORS

          Investing in our securities involves a number of significant risks. In addition to the other information contained in this prospectus supplement and the accompanying prospectus, you should consider carefully the following risks before making an investment in our securities. The risks set out below are not the only risks we face and you should read the risks set out in "Risk Factors" beginning on page 22 of the accompanying prospectus. Additional risks and uncertainties not presently known to us or not presently deemed material by us might also impair our operations and performance. If any of the following events occur, our business, financial condition and results of operations could be materially and adversely affected. In such case, our net asset value and the trading price of our common stock could decline and you may lose all or part of your investment.

Uncertainty relating to the LIBOR calculation process may adversely affect the value of our portfolio of LIBOR-indexed, floating-rate debt securities.

          Concerns have been publicized that some of the member banks surveyed by the British Bankers' Association, or the "BBA," in connection with the calculation of LIBOR across a range of maturities and currencies may have been under-reporting or otherwise manipulating the inter-bank lending rate applicable to them in order to profit on their derivatives positions or to avoid an appearance of capital insufficiency or adverse reputational or other consequences that may have resulted from reporting inter-bank lending rates higher than those they actually submitted. A number of BBA member banks have entered into settlements with their regulators and law enforcement agencies with respect to alleged manipulation of LIBOR, and investigations by regulators and governmental authorities in various jurisdictions are ongoing.

          On July 27, 2017, the United Kingdom's Financial Conduct Authority, which regulates LIBOR, announced that it intends to phase out LIBOR by the end of 2021. It is unclear if at that time whether or not LIBOR will cease to exist or if new methods of calculating LIBOR will be established such that it continues to exist after 2021. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large US financial institutions, is considering replacing U.S. dollar LIBOR with a new index calculated by short-term repurchase agreements, backed by Treasury securities called the Secured Overnight Financing Rate ("SOFR"). The first publication of SOFR was released in April 2018. Whether or not SOFR attains market traction as a LIBOR replacement remains a question and future of LIBOR at this time is uncertain. If LIBOR ceases to exist, we may need to renegotiate the credit agreements extending beyond 2021 with our portfolio companies that utilize LIBOR as a factor in determining the interest rate to replace LIBOR with the new standard that is established, which may have an adverse effect on our results of operations. In addition, if LIBOR ceases to exist, we may need to renegotiate any LIBOR based revolving credit facilities to replace LIBOR with the new standard that is established in its place. If we are unable to do so, amounts drawn under the revolving credit facility may bear interest at a higher rate, which would increase the cost of our borrowings and, in turn, affect our results of operations.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

          This prospectus supplement and the accompanying prospectus contain forward-looking statements that involve substantial risks and uncertainties. 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 supplement and the accompanying prospectus involve risks and uncertainties, including statements as to:

          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:

          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 supplement or the accompanying prospectus should not be

USE OF PROCEEDS

          We estimate that we will receive net proceeds from the sale of the 8,000,000 shares of our common stock in this offering of approximately $              million, after deducting underwriting discounts and commissions of approximately $              million and estimated offering expenses of approximately $0.3 million payable by us. In addition, the Investment Adviser has agreed to bear $              million of sales load in connection with this offering, which will not be subject to reimbursement by us. Certain of our officers and interested directors listed in the "Underwriting" section of this prospectus supplement have submitted a non-binding indication of interest to purchase an aggregate of 400,000 shares of the common stock in connection with this offering. As per an arrangement with the underwriters, we and the Investment Adviser will not pay and the underwriters will not receive the sales load on the shares that certain of our officers and interested directors expect to purchase in this offering. If the underwriters' option to purchase additional shares is exercised in full, our net proceeds from this offering will be approximately $              million, after deducting underwriting discounts and commissions of approximately $              million and estimated offering expenses of approximately $0.3 million payable by us. In addition, if the underwriters' option to purchase additional shares is exercised in full, the Investment Adviser has agreed to bear $              million of sales load in connection with this offering, which will not be subject to reimbursement by us.

          We intend to use the net proceeds from this offering primarily for new investments in portfolio companies in accordance with our investment objective and strategies described in this prospectus supplement and the accompanying prospectus. We may also use a portion of the net proceeds from the sale of shares of our common stock sold in this offering for other general corporate purposes, including to temporarily repay indebtedness (which will be subject to reborrowing), and other working capital requirements. 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.

          We expect that it will take up to three months for us to substantially invest the net proceeds from this offering, depending on the availability of attractive opportunities and market conditions. 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 temporary investments are expected to provide a lower net return than we hope to achieve from our target investments and, accordingly, may result in lower distributions, if any, during such period.

          On October 21, 2019, the last reported sales price of our common stock was $13.51 per share. As of October 21, 2019, we had approximately fourteen stockholders of record and approximately 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 October 21, 2019, our shares of common stock traded at a premium of approximately 0.7% of the NAV

attributable to those shares as of June 30, 2019. 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 tax purposes. Generally, a return of capital will reduce an investor's basis in our stock for U.S. federal income tax purposes, which will result in a higher tax liability when the stock is sold. 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 NYSE on the distribution payment date. Market price per share on that date will be the closing price for such shares on the NYSE 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.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

          The information contained in this section should be read in conjunction with the Selected Financial and Other Data and our Financial Statements and notes thereto appearing elsewhere in this prospectus supplement and the accompanying prospectus. The following discussion and other parts of this prospectus supplement and the accompanying prospectus contain forward-looking information that involves risks and uncertainties. Our actual results could differ materially from those anticipated by such forward-looking information due to the factors discussed under "Cautionary Statement Regarding Forward-Looking Statements" appearing elsewhere 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 IPO on May 19, 2011. We are a closed-end, non-diversified management investment company that has elected to be regulated as a BDC under the 1940 Act. We have elected to be treated, and intend to comply with the requirements to continue to qualify annually, as a RIC under Subchapter M of the Code). NMFC is also registered as an investment adviser under the Advisers Act. Since our IPO, and through June 30, 2019, we raised approximately $673.9 million in net proceeds from additional offerings of our common stock.

          The Investment Adviser is a wholly-owned subsidiary of New Mountain Capital. New Mountain Capital is a firm with a track record of investing in the middle market. New Mountain Capital focuses on investing in defensive growth companies across its private equity, public equity and credit investment vehicles. 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, a wholly-owned subsidiary of New Mountain Capital, provides the administrative services necessary to conduct our day-to-day operations.

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

          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, including first and second lien debt, notes, bonds and mezzanine securities. The first lien debt may include traditional first lien senior secured loans or unitranche loans. Unitranche loans combine characteristics of traditional first lien senior secured loans as well as second lien and subordinated loans. Unitranche loans will expose us to

S-33


Table of Contents

the risks associated with second lien and subordinated loans to the extent we invest in the "last out" tranche. 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) sustainable secular growth drivers, (ii) high barriers to competitive entry, (iii) high free cash flow after capital expenditure and working capital needs, (iv) high returns on assets and (v) niche market dominance. Similar to us, SBIC I's and SBIC II's investment objectives are to generate current income and capital appreciation under our investment criteria. However, SBIC I's and SBIC II's investments must be in SBA eligible small businesses. Our portfolio may be concentrated in a limited number of industries. As of June 30, 2019, our top five industry concentrations were business services, software, healthcare services, education and investment funds (which includes our investments in our joint ventures).

          As of June 30, 2019, our net asset value was approximately $1,080.9 million and our portfolio had a fair value of approximately $2,643.1 million in 101 portfolio companies, with a YTM at Cost of approximately 9.4% and a YTM at Cost for Investments of approximately 9.4%. The 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. The 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 LIBOR curves at each quarter's end date. The actual yield to maturity may be higher or lower due to the future selection of the LIBOR contracts by the individual companies in our portfolio or other factors.

Recent Developments

Common Stock Offering

          On July 11, 2019, we completed a public offering of 6,900,000 shares of our common stock at a public offering price of $13.68 per share. Our Investment Adviser paid a $0.39 per share portion of the $0.42 per share underwriters' sales load such that we received net proceeds of $13.65 per share in this offering. All payments made by our Investment Adviser are not subject to reimbursement by us. We received total net proceeds of approximately $94.2 million in connection with this offering.

Distribution Announcement

          On August 1, 2019, our board of directors declared a third quarter 2019 distribution of $0.34 per share which was paid on September 27, 2019 to holders of record as of September 13, 2019.

Credit Facility Amendments

          On August 12, 2019, we entered into Amendment No. 3 to the Loan Financing and Servicing Agreement (the "Third Amendment"), which amended the DB Credit Facility, by and among the Company, as the equityholder and the servicer, NMFDB, as the borrower, Deutsche Bank AG, New York Branch ("DBNY"), as the facility agent, U.S. Bank National Association, as the collateral agent and collateral custodian, and DBNY as agent and lender, and each of the other agents and lenders from time to time party thereto.

          Pursuant to the Third Amendment, among other things, (i) DBNY assigned portions of its commitments under the DB Credit Facility to KeyBank National Association ("KeyBank") and Customers Bank ("Customers"), and KeyBank and Customers upsized their respective commitments under the DB Credit Facility, such that the aggregate commitments under, and maximum facility amount of, the DB Credit

S-34


Table of Contents

Facility increased from $150.0 million to $210.0 million, and (ii) certain other customary modifications were made to the DB Credit Facility, as set forth in Appendix A to the Third Amendment.

          The DB Credit Facility continues to have a revolving period ending on December 14, 2021 and will still mature on December 14, 2023.

          On August 27, 2019, we entered into a Commitment Agreement related to the NMFC Credit Facility. The Commitment Agreement increases the total commitments under the NMFC Credit Facility from $135.0 million to $138.5 million from existing lenders in accordance with the accordion feature of the NMFC Credit Facility.

          On September 6, 2019, we entered into (i) certain Joinders to add Old Second National Bank and Raymond James Bank, N.A., each as new lenders under the Holdings Credit Facility, (ii) a Facility Increase Agreement with State Street Bank and Trust Company to increase its commitment under the Holdings Credit Facility and (iii) Commitment Supplement with CIT Bank, N.A. to increase its commitment under the Holdings Credit Facility. After giving effect to the Joinders, the Facility Increase Agreement and the Commitment Supplement, the aggregate commitments of the lenders under the Holdings Credit Facility equals $800.0 million. The Holdings Credit Facility continues to have a revolving period ending on October 24, 2020, and will still mature on October 24, 2022.

          On October 16, 2019, we entered into a Joinder Agreement pursuant to which Hitachi Capital America Corp. was added as a lender under the DB Credit Facility for an aggregate commitment of $20.0 million thereby increasing the aggregate commitments under the DB Credit Facility from $210.0 million to $230.0 million.

Co-investment Order

          On October 8, 2019, the SEC issued an exemptive order (the "New Order") permitting us and certain of our affiliates to co-invest together in portfolio companies subject to certain conditions included therein. The New Order supersedes our existing co-investment exemptive order, which was granted by the SEC on December 18, 2017, and expands on our ability to co-invest with certain affiliates.

New Director

          On September 13, 2019, our Board of Directors appointed Daniel B. Hébert as a Class III director with a term that expires at the Company's 2020 annual meeting of stockholders. Additionally, Mr. Hébert was appointed to the Company's Audit Committee, Valuation Committee, Compensation Committee and Nominating and Corporate Governance Committee. Mr. Hébert was previously a member of the Company's Board of Directors from August 2011 until March 2012.

          Since May 2017, Mr. Hébert has been the Co-Founder and Chief Operating Officer of Bernstein Equity Partners LLC, an investment banking firm. From October 2013 until April 2017, Mr. Hébert was a Managing Director at Sandler & O'Neill, an investment banking firm. He served as a Partner and Managing Director at North Sea Partners LLC, an investment banking firm, from 2011 until September 2013. Mr. Hébert received his B.A. from Acadia University and his M.B.A. from the Richard Ivey School of Business. Mr. Hébert brings his experience in investment banking to our board of directors. This background positions Mr. Hébert well to serve as our director.

          Mr. Hébert is not an "interested person" of the Company as such term is defined under the 1940 Act. Therefore, the Company's Board of Directors now consists of a majority of non-interested persons, which requirement was suspended for 90 days from June 17, 2019, in accordance with Section 56(b) of the 1940 Act, due to the untimely death of Mr. Kurt Wolfgruber, our former director.

Preliminary Estimates of Net Asset Value and Net Investment Income

          Set forth below is a preliminary estimate of our net asset value per share as of September 30, 2019 and a preliminary estimate of our net investment income per share range for the three months ended September 30, 2019. The following estimates are not a comprehensive statement of our financial condition or results for the period ended September 30, 2019. We advise you that our actual results for the three months ended September 30, 2019 may differ materially from these estimates, which are given only as of the date of this prospectus supplement, as a result of the completion of our financial closing procedures, final adjustments and other developments, including changes in interest rates, changes in the businesses to whom we have made loans or market and industry fluctuations, which may arise between now and the time that our financial results for the three months ended September 30, 2019 are finalized. This information is inherently uncertain.

          As of the date of this prospectus supplement, we estimate that our net asset value per share as of September 30, 2019 was approximately $13.30 to $13.40. As of the date of this prospectus supplement, we currently expect that our net investment income per share was between $0.35 and $0.36 for the three months ended September 30, 2019.

          The preliminary financial estimates provided herein have been prepared by, and are the responsibility of, management. Neither Deloitte & Touche LLP, our independent registered public accounting firm, nor any other independent accountants have audited, reviewed, compiled, or performed any procedures with respect to the accompanying preliminary financial data. Accordingly, Deloitte & Touche LLP does not express an opinion or any form of assurance with respect thereto and assumes no responsibility for, and disclaims any association with, this information.

Critical Accounting Policies

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

Basis of Accounting

          We consolidate our wholly-owned direct and indirect subsidiaries: NMF Holdings, NMF Servicing, NMNLC, NMFDB, SBIC I, SBIC I GP, SBIC II, SBIC II GP, NMF Ancora, NMF QID and NMF YP. We are an investment company following accounting and reporting guidance as described in Accounting Standards Codification Topic 946, Financial Services — Investment Companies, ("ASC 946").

Valuation and Leveling of Portfolio Investments

          At all times consistent with GAAP and the 1940 Act, we conduct a valuation of assets, which impacts our net asset value.

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

S-36


Table of Contents

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

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

S-37


Table of Contents

market value, the fair value of our investments may fluctuate from period to period and the fluctuations could be material.

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

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

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

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

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

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

          The following table summarizes the levels in the fair value hierarchy that our portfolio investments fall into as of June 30, 2019:

(in thousands)
  Total   Level I   Level II   Level III

Total investments

  $ 2,643,096   $   $ 614,654   $ 2,028,442  

          We generally use the following framework when determining the fair value of investments where there are little, if any, market activity or observable pricing inputs. We typically determine the fair value of our performing debt investments utilizing an income approach. Additional consideration is given

S-38


Table of Contents

using a market based approach, as well as reviewing the overall underlying portfolio company's performance and associated financial risks. The following outlines additional details on the approaches considered:

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

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

          Market Based Approach:    We may estimate the total enterprise value of each portfolio company by utilizing market value cash flow (EBITDA) multiples of publicly traded comparable companies and comparable transactions. We consider numerous factors when selecting the appropriate companies whose trading multiples are used to value our portfolio companies. These factors include, but are not limited to, the type of organization, similarity to the business being valued, and relevant risk factors, as well as size, profitability and growth expectations. We may apply an average of various relevant comparable company EBITDA multiples to the portfolio company's latest twelve month ("LTM") EBITDA or projected EBITDA to calculate the enterprise value of the portfolio company. Significant increases or decreases in the EBITDA multiple will result in an increase or decrease in enterprise value, which may result in an increase or decrease in the fair value estimate of the investment. In applying the market based approach as of June 30, 2019, we used the relevant EBITDA multiple ranges set forth in the table below to determine the enterprise value of our portfolio companies. We believe these were reasonable ranges in light of current comparable company trading levels and the specific portfolio companies involved.

          Income Based Approach:    We also may use a discounted cash flow analysis to estimate the fair value of the investment. Projected cash flows represent the relevant security's contractual interest, fee and principal payments plus the assumption of full principal recovery at the investment's expected maturity date. These cash flows are discounted at a rate established utilizing a yield calibration approach, which incorporates changes in the credit quality (as measured by relevant statistics) of the portfolio company, as compared to changes in the yield associated with comparable credit quality market indices, between the date of origination and the valuation date. Significant increases or decreases in the discount rate would result in a decrease or increase in the fair value measurement. In applying the income based approach as of June 30, 2019, we used the discount ranges set forth in the table below to value investments in our portfolio companies.

owned investment company subsidiary. Furthermore, Accounting Standards Codification Topic 810, Consolidation ("ASC 810"), concludes that in a joint venture where both members have equal decision making authority, it is not appropriate for one member to consolidate the joint venture since neither has control. Accordingly, we do not consolidate SLP II.

NMFC Senior Loan Program III LLC

          SLP III was formed as a Delaware limited liability company and commenced operations on April 25, 2018. SLP III is structured as a private joint venture investment fund between us and SkyKnight Income II, LLC ("SkyKnight II") and operates under a limited liability company agreement (the "SLP III Agreement"). The purpose of the joint venture is to invest primarily in senior secured loans issued by portfolio companies within our core industry verticals. These investments are typically broadly syndicated first lien loans. All investment decisions must be unanimously approved by the board of managers of SLP III, which has equal representation from us and SkyKnight II. SLP III has a five year investment period and will continue in existence until April 25, 2025. The investment period may be extended for up to one year pursuant to certain terms of the SLP III Agreement.

          SLP III is capitalized with equity contributions which are called from its members, on a pro-rata basis based on their equity commitments, as transactions are completed. Any decision by SLP III to call down on capital commitments requires approval by the board of managers of SLP III. As of June 30, 2019, we and SkyKnight II have committed $100.0 million and $25.0 million, respectively, of equity to SLP III. As of June 30, 2019, the Company and SkyKnight II have contributed $80.0 million and $20.0 million, respectively, of equity to SLP III. Our investment in SLP III is disclosed on our Consolidated Schedule of Investments as of June 30, 2019 and December 31, 2018.

          On May 2, 2018, SLP III closed its revolving credit facility with Citibank, N.A., which matures on May 2, 2023 and bears interest at a rate of LIBOR plus 1.70% per annum. Effective June 24, 2019, SLP III's revolving credit facility has a maximum borrowing capacity of $375.0 million. As of June 30, 2019 and December 31, 2018, SLP III had total investments with an aggregate fair value of approximately $441.7 million and $365.4 million, respectively, and debt outstanding under its credit facility of $288.3 million and $280.3 million, respectively.

SLP III commenced operations on April 25, 2018.

          For the three and six months ended June 30, 2019, we earned approximately $2.2 million and $4.9 million of dividend income related to SLP III, which is included in dividend income. For the three and six months ended June 30, 2018, we did not earn any dividend income related to SLP III. As of June 30, 2019 and December 31, 2018 approximately $2.2 million and $2.1 million, respectively, of dividend income related to SLP III was included in interest and dividend receivable.

          We have determined that SLP III is an investment company under ASC 946; however, in accordance with such guidance we will generally not consolidate our investment in a company other than a wholly-owned investment company subsidiary. Furthermore, ASC 810 concludes that in a joint venture where both members have equal decision making authority, it is not appropriate for one member to consolidate the joint venture since neither has control. Accordingly, we do not consolidate SLP III.
