(1)
All investments are Lower Middle Market portfolio investments, unless otherwise noted. See Note B for a description of Lower Middle Market portfolio investments. All of the Company's investments, unless otherwise noted, are encumbered either as security for the Company's Credit Facility or in support of the SBA-guaranteed debentures issued by the Funds.

(2)
Debt investments are income producing, unless otherwise noted. Equity and warrants are non-income producing, unless otherwise noted.

(3)
See Note C and Schedule 12-14 for a summary of geographic location of portfolio companies.

(4)
Principal is net of repayments. Cost is net of repayments and accumulated unearned income.

(5)
Control investments are defined by the Investment Company Act of 1940, as amended ("1940 Act"), as investments in which more than 25% of the voting securities are owned or where the ability to nominate greater than 50% of the board representation is maintained.

(6)
Affiliate investments are defined by the 1940 Act as investments in which between 5% and 25% (inclusive) of the voting securities are owned and the investments are not classified as Control investments.

(7)
Non-Control/Non-Affiliate investments are defined by the 1940 Act as investments that are neither Control investments nor Affiliate investments.

(8)
Income producing through dividends or distributions.

(9)
Index based floating interest rate is subject to contractual minimum interest rate. A majority of the variable rate loans in the Company's investment portfolio bear interest at a rate that may be determined by reference to either LIBOR or an alternate Base Rate (commonly based on the Federal Funds Rate or the Prime Rate), which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan. For each such loan, the Company has provided the weighted average annual stated interest rate in effect at June 30, 2020. As noted in this schedule, 60% of the loans (based on the par amount) contain LIBOR floors which range between 0.50% and 2.00%, with a weighted-average LIBOR floor of approximately 1.09%.

(10)
Private Loan portfolio investment. See Note B for a description of Private Loan portfolio investments.

(11)
Middle Market portfolio investment. See Note B for a description of Middle Market portfolio investments.

(12)
Other Portfolio investment. See Note B for a description of Other Portfolio investments.

(13)
Investment is not a qualifying asset as defined under Section 55(a) of the 1940 Act. Qualifying assets must represent at least 70% of total assets at the time of acquisition of any additional non-qualifying assets.

(14)
Non-accrual and non-income producing investment.

(15)
Portfolio company is in a bankruptcy process and, as such, the maturity date of our debt investment in this portfolio company will not be finally determined until such process is complete. As noted in footnote (14), our debt investment in this portfolio company is on non-accrual status.

(16)
External Investment Manager. Investment is not encumbered as security for the Company's Credit Facility or in support of the SBA-guaranteed debentures issued by the Funds.

(17)
Maturity date is under on-going negotiations with the portfolio company and other lenders, if applicable.

(18)
Investment fair value was determined using significant unobservable inputs, unless otherwise noted. See Note C for further discussion.

(19)
PIK interest income and cumulative dividend income represent income not paid currently in cash.

(20)
All portfolio company headquarters are based in the United States, unless otherwise noted.

(21)
Portfolio company headquarters are located outside of the United States.

(22)
In connection with the Company's debt investment in Staples Canada ULC and in an attempt to mitigate any potential adverse change in foreign exchange rates during the term of the Company's investment, the Company maintains a forward foreign currency contract with Cadence Bank to lend $16.7 million Canadian Dollars and receive $12.8 million U.S. Dollars with a settlement date of September 14, 2020. The unrealized appreciation on the forward foreign currency contract is $0.4 million as of June 30, 2020.

(23)
The Company has entered into an intercreditor agreement that entitles the Company to the "last out" tranche of the first lien secured loans, whereby the "first out" tranche will receive priority as to the "last out" tranche with respect to payments of principal, interest, and any other amounts due thereunder. Therefore, the Company receives a higher interest rate than the contractual stated interest rate of LIBOR plus 8.50% (Floor 1.00%) per the credit agreement and the Consolidated Schedule of Investments above reflects such higher rate.

(24)
Investment has an unfunded commitment as of June 30, 2020 (see Note K). The fair value of the investment includes the impact of the fair value of any unfunded commitments.

(25)
All of the Company's portfolio investments are generally subject to restrictions on resale as "restricted securities."

(26)
Investment date represents the date of initial investment in the portfolio company.

NOTE A—ORGANIZATION AND BASIS OF PRESENTATION

1.     Organization

        Main Street Capital Corporation ("MSCC") is a principal investment firm primarily focused on providing customized debt and equity financing to lower middle market ("LMM") companies and debt capital to middle market ("Middle Market") companies. The portfolio investments of MSCC and its consolidated subsidiaries are typically made to support management buyouts, recapitalizations, growth financings, refinancings and acquisitions of companies that operate in a variety of industry sectors. MSCC seeks to partner with entrepreneurs, business owners and management teams and generally provides "one stop" financing alternatives within its LMM portfolio. MSCC and its consolidated subsidiaries invest primarily in secured debt investments, equity investments, warrants and other securities of LMM companies based in the United States and in secured debt investments of Middle Market companies generally headquartered in the United States.

        MSCC was formed in March 2007 to operate as an internally managed business development company ("BDC") under the Investment Company Act of 1940, as amended (the "1940 Act"). MSCC wholly owns several investment funds, including Main Street Mezzanine Fund, LP ("MSMF"), Main Street Capital II, LP ("MSC II") and Main Street Capital III, LP ("MSC III" and, collectively with MSMF and MSC II, the "Funds"), and each of their general partners. The Funds are each licensed as a Small Business Investment Company ("SBIC") by the United States Small Business Administration ("SBA"). Because MSCC is internally managed, all of the executive officers and other employees are employed by MSCC. Therefore, MSCC does not pay any external investment advisory fees, but instead directly incurs the operating costs associated with employing investment and portfolio management professionals.

        MSC Adviser I, LLC (the "External Investment Manager") was formed in November 2013 as a wholly owned subsidiary of MSCC to provide investment management and other services to parties other than MSCC and its subsidiaries or their portfolio companies ("External Parties") and receives fee income for such services. MSCC has been granted no-action relief by the Securities and Exchange Commission ("SEC") to allow the External Investment Manager to register as a registered investment adviser under the Investment Advisers Act of 1940, as amended. Since the External Investment Manager conducts all of its investment management activities for External Parties, it is accounted for as a portfolio investment of MSCC and is not included as a consolidated subsidiary of MSCC in MSCC's consolidated financial statements.

        MSCC has elected to be treated for U.S. federal income tax purposes as a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). As a result, MSCC generally will not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that it distributes to its stockholders.

        MSCC has certain direct and indirect wholly owned subsidiaries that have elected to be taxable entities (the "Taxable Subsidiaries"). The primary purpose of the Taxable Subsidiaries is to permit MSCC to hold equity investments in portfolio companies which are "pass-through" entities for tax purposes.

        Unless otherwise noted or the context otherwise indicates, the terms "we," "us," "our," the "Company" and "Main Street" refer to MSCC and its consolidated subsidiaries, which include the Funds and the Taxable Subsidiaries.

2.     Basis of Presentation

        Main Street's consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"). The Company is an investment company following accounting and reporting guidance in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 946, Financial Services—Investment Companies ("ASC 946"). For each of the periods presented herein, Main Street's consolidated financial statements include the accounts of MSCC and its consolidated subsidiaries. The Investment Portfolio, as used herein, refers to all of Main Street's investments in LMM portfolio companies, investments in Middle Market portfolio companies, private loan ("Private Loan") portfolio investments, other portfolio ("Other Portfolio") investments and the investment in the External Investment Manager (see "Note C—Fair Value Hierarchy for Investments and Debentures—Portfolio Composition—Investment Portfolio Composition" for additional discussion of Main Street's Investment Portfolio). Main Street's results of operations for the three and six months ended June 30, 2020 and 2019, cash flows for the six months ended June 30, 2020 and 2019, and financial position as of June 30, 2020 and December 31, 2019, are presented on a consolidated basis. The effects of all intercompany transactions between Main Street and its consolidated subsidiaries have been eliminated in consolidation.

        The accompanying unaudited consolidated financial statements of Main Street are presented in conformity with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Articles 6, 10 and 12 of Regulation S-X. Accordingly, certain disclosures accompanying annual financial statements prepared in accordance with U.S. GAAP are omitted. In the opinion of management, the unaudited consolidated financial results included herein contain all adjustments, consisting solely of normal recurring accruals, considered necessary for the fair presentation of financial statements for the interim periods included herein. The results of operations for the three and six months ended June 30, 2020 and 2019 are not necessarily indicative of the operating results to be expected for the full year. Also, the unaudited financial statements and notes should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2019. Financial statements prepared on a U.S. GAAP basis require management to make estimates and assumptions that affect the amounts and disclosures reported in the financial statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein.

        Under ASC 946, Main Street is precluded from consolidating other entities in which Main Street has equity investments, including those in which it has a controlling interest, unless the other entity is another investment company. An exception to this general principle in ASC 946 occurs if Main Street holds a controlling interest in an operating company that provides all or substantially all of its services directly to Main Street or to its portfolio companies. Accordingly, as noted above, MSCC's consolidated financial statements include the financial position and operating results for the Funds and the Taxable Subsidiaries. Main Street has determined that none of its portfolio investments qualify for this exception, including the investment in the External Investment Manager. Therefore, Main Street's Investment Portfolio is carried on the consolidated balance sheet at fair value, as discussed further in Note B.1., with any adjustments to fair value recognized as "Net Unrealized Appreciation (Depreciation)" on the consolidated statements of operations until the investment is realized, usually upon exit, resulting in any gain or loss being recognized as a "Net Realized Gain (Loss)."

    Portfolio Investment Classification

        Main Street classifies its Investment Portfolio in accordance with the requirements of the 1940 Act. Under the 1940 Act, (a) "Control Investments" are defined as investments in which Main Street owns more than 25% of the voting securities or has rights to maintain greater than 50% of the board representation, (b) "Affiliate Investments" are defined as investments in which Main Street owns between 5% and 25% (inclusive) of the voting securities and does not have rights to maintain greater than 50% of the board representation, and (c) "Non-Control/Non-Affiliate Investments" are defined as investments that are neither Control Investments nor Affiliate Investments.

NOTE B—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

1.     Valuation of the Investment Portfolio

        Main Street accounts for its Investment Portfolio at fair value. As a result, Main Street follows the provisions of ASC 820, Fair Value Measurements and Disclosures ("ASC 820"). ASC 820 defines fair value, establishes a framework for measuring fair value, establishes a fair value hierarchy based on the quality of inputs used to measure fair value and enhances disclosure requirements for fair value measurements. ASC 820 requires Main Street to assume that the portfolio investment is to be sold in the principal market to independent market participants, which may be a hypothetical market. Market participants are defined as buyers and sellers in the principal market that are independent, knowledgeable and willing and able to transact.

        Main Street's portfolio strategy calls for it to invest primarily in illiquid debt and equity securities issued by privately held, LMM companies and more liquid debt securities issued by Middle Market companies that are generally larger in size than the LMM companies. Main Street categorizes some of its investments in LMM companies and Middle Market companies as Private Loan portfolio investments, which are primarily debt securities in privately held companies that have been originated through strategic relationships with other investment funds on a collaborative basis, and are often referred to in the debt markets as "club deals." Private Loan investments are typically similar in size, structure, terms and conditions to investments Main Street holds in its LMM portfolio and Middle Market portfolio. Main Street's portfolio also includes Other Portfolio investments which primarily consist of investments that are not consistent with the typical profiles for its LMM portfolio investments, Middle Market portfolio investments or Private Loan portfolio investments, including investments which may be managed by third parties. Main Street's portfolio investments may be subject to restrictions on resale.

        LMM investments and Other Portfolio investments generally have no established trading market while Middle Market securities generally have established markets that are not active. Private Loan investments may include investments which have no established trading market or have established markets that are not active. Main Street determines in good faith the fair value of its Investment Portfolio pursuant to a valuation policy in accordance with ASC 820 and a valuation process approved by its Board of Directors and in accordance with the 1940 Act. Main Street's valuation policies and processes are intended to provide a consistent basis for determining the fair value of Main Street's Investment Portfolio.

        For LMM portfolio investments, Main Street generally reviews external events, including private mergers, sales and acquisitions involving comparable companies, and includes these events in the valuation process by using an enterprise value waterfall methodology ("Waterfall") for its LMM equity

investments and an income approach using a yield-to-maturity model ("Yield-to-Maturity") for its LMM debt investments. For Middle Market portfolio investments, Main Street primarily uses quoted prices in the valuation process. Main Street determines the appropriateness of the use of third-party broker quotes, if any, in determining fair value based on its understanding of the level of actual transactions used by the broker to develop the quote and whether the quote was an indicative price or binding offer, the depth and consistency of broker quotes and the correlation of changes in broker quotes with underlying performance of the portfolio company and other market indices. For Middle Market and Private Loan portfolio investments in debt securities for which it has determined that third-party quotes or other independent pricing are not available or appropriate, Main Street generally estimates the fair value based on the assumptions that it believes hypothetical market participants would use to value the investment in a current hypothetical sale using the Yield-to-Maturity valuation method. For its Other Portfolio equity investments, Main Street generally calculates the fair value of the investment primarily based on the net asset value ("NAV") of the fund and adjusts the fair value for other factors deemed relevant that would affect the fair value of the investment. All of the valuation approaches for Main Street's portfolio investments estimate the value of the investment as if Main Street were to sell, or exit, the investment as of the measurement date.

        These valuation approaches consider the value associated with Main Street's ability to control the capital structure of the portfolio company, as well as the timing of a potential exit. For valuation purposes, "control" portfolio investments are composed of debt and equity securities in companies for which Main Street has a controlling interest in the equity ownership of the portfolio company or the ability to nominate a majority of the portfolio company's board of directors. For valuation purposes, "non-control" portfolio investments are generally composed of debt and equity securities in companies for which Main Street does not have a controlling interest in the equity ownership of the portfolio company or the ability to nominate a majority of the portfolio company's board of directors.

        Under the Waterfall valuation method, Main Street estimates the enterprise value of a portfolio company using a combination of market and income approaches or other appropriate valuation methods, such as considering recent transactions in the equity securities of the portfolio company or third-party valuations of the portfolio company, and then performs a waterfall calculation by allocating the enterprise value over the portfolio company's securities in order of their preference relative to one another. The enterprise value is the fair value at which an enterprise could be sold in a transaction between two willing parties, other than through a forced or liquidation sale. Typically, privately held companies are bought and sold based on multiples of earnings before interest, taxes, depreciation and amortization ("EBITDA"), cash flows, net income, revenues, or in limited cases, book value. There is no single methodology for estimating enterprise value. For any one portfolio company, enterprise value is generally described as a range of values from which a single estimate of enterprise value is derived. In estimating the enterprise value of a portfolio company, Main Street analyzes various factors including the portfolio company's historical and projected financial results. Due to SEC deadlines for Main Street's quarterly and annual financial reporting, the operating results of a portfolio company used in the current period valuation are generally the results from the period ended three months prior to such valuation date and may include unaudited, projected, budgeted or pro forma financial information and may require adjustments for non-recurring items or to normalize the operating results that may require significant judgment in determining. In addition, projecting future financial results requires significant judgment regarding future growth assumptions. In evaluating the operating results, Main Street also analyzes the impact of exposure to litigation, loss of customers or other contingencies. After determining the appropriate enterprise value, Main Street allocates the enterprise value to

investments in order of the legal priority of the various components of the portfolio company's capital structure. In applying the Waterfall valuation method, Main Street assumes the loans are paid off at the principal amount in a change in control transaction and are not assumed by the buyer, which Main Street believes is consistent with its past transaction history and standard industry practices.

        Under the Yield-to-Maturity valuation method, Main Street also uses the income approach to determine the fair value of debt securities based on projections of the discounted future free cash flows that the debt security will likely generate, including analyzing the discounted cash flows of interest and principal amounts for the debt security, as set forth in the associated loan agreements, as well as the financial position and credit risk of the portfolio company. Main Street's estimate of the expected repayment date of its debt securities is generally the maturity date of the instrument, as Main Street generally intends to hold its loans and debt securities to maturity. The Yield-to-Maturity analysis also considers changes in leverage levels, credit quality, portfolio company performance and other factors. Main Street will generally use the value determined by the Yield-to-Maturity analysis as the fair value for that security; however, because of Main Street's general intent to hold its loans to maturity, the fair value will not exceed the principal amount of the debt security valued using the Yield-to-Maturity valuation method. A change in the assumptions that Main Street uses to estimate the fair value of its debt securities using the Yield-to-Maturity valuation method could have a material impact on the determination of fair value. If there is deterioration in credit quality or if a debt security is in workout status, Main Street may consider other factors in determining the fair value of the debt security, including the value attributable to the debt security from the enterprise value of the portfolio company or the proceeds that would most likely be received in a liquidation analysis.

        Under the NAV valuation method, for an investment in an investment fund that does not have a readily determinable fair value, Main Street measures the fair value of the investment predominately based on the NAV of the investment fund as of the measurement date and adjusts the investment's fair value for factors known to Main Street that would affect that fund's NAV, including, but not limited to, fair values for individual investments held by the fund if Main Street holds the same investment or for a publicly traded investment. In addition, in determining the fair value of the investment, Main Street considers whether adjustments to the NAV are necessary in certain circumstances, based on the analysis of any restrictions on redemption of Main Street's investment as of the measurement date, recent actual sales or redemptions of interests in the investment fund, and expected future cash flows available to equity holders, including the rate of return on those cash flows compared to an implied market return on equity required by market participants, or other uncertainties surrounding Main Street's ability to realize the full NAV of its interests in the investment fund.

        Pursuant to its internal valuation process and the requirements under the 1940 Act, Main Street performs valuation procedures on each of its portfolio investments quarterly. In addition to its internal valuation process, in arriving at estimates of fair value for its investments in its LMM portfolio companies, Main Street, among other things, consults with a nationally recognized independent financial advisory services firm. The nationally recognized independent financial advisory services firm analyzes and provides observations, recommendations and an assurance certification regarding the Company's determinations of the fair value of its LMM portfolio company investments. The nationally recognized independent financial advisory services firm is generally consulted relative to Main Street's investments in each LMM portfolio company at least once every calendar year, and for Main Street's investments in new LMM portfolio companies, at least once in the twelve-month period subsequent to the initial investment. In certain instances, Main Street may determine that it is not cost-effective, and as a result is not in its stockholders' best interest, to consult with the nationally recognized independent

financial advisory services firm on its investments in one or more LMM portfolio companies. Such instances include, but are not limited to, situations where the fair value of Main Street's investment in a LMM portfolio company is determined to be insignificant relative to the total Investment Portfolio. Main Street consulted with and received an assurance certification from its independent financial advisory services firm in arriving at Main Street's determination of fair value on its investments in a total of 28 LMM portfolio companies for the six months ended June 30, 2020, representing approximately 47% of the total LMM portfolio at fair value as of June 30, 2020, and on a total of 25 LMM portfolio companies for the six months ended June 30, 2019, representing approximately 40% of the total LMM portfolio at fair value as of June 30, 2019. Excluding its investments in LMM portfolio companies that, as of June 30, 2020 and 2019, as applicable, had not been in the Investment Portfolio for at least twelve months subsequent to the initial investment or whose primary purpose is to own real estate for which a third-party appraisal is obtained on at least an annual basis, the percentage of the LMM portfolio reviewed and certified by its independent financial advisory services firm for the six months ended June 30, 2020 and 2019 was 53% and 42% of the total LMM portfolio at fair value as of June 30, 2020 and 2019, respectively.

        For valuation purposes, all of Main Street's Middle Market portfolio investments are non-control investments. To the extent sufficient observable inputs are available to determine fair value, Main Street uses observable inputs to determine the fair value of these investments through obtaining third-party quotes or other independent pricing. For Middle Market portfolio investments for which it has determined that third-party quotes or other independent pricing are not available or appropriate, Main Street generally estimates the fair value based on the assumptions that it believes hypothetical market participants would use to value such Middle Market debt investments in a current hypothetical sale using the Yield-to-Maturity valuation method and such Middle Market equity investments in a current hypothetical sale using the Waterfall valuation method. Because the vast majority of the Middle Market portfolio investments are typically valued using third-party quotes or other independent pricing services (including 92% and 91% of the Middle Market portfolio investments as of June 30, 2020 and December 31, 2019, respectively), Main Street generally does not consult with any financial advisory services firms in connection with determining the fair value of its Middle Market investments.

        For valuation purposes, all of Main Street's Private Loan portfolio investments are non-control investments. For Private Loan portfolio investments for which it has determined that third-party quotes or other independent pricing are not available or appropriate, Main Street generally estimates the fair value based on the assumptions that it believes hypothetical market participants would use to value such Private Loan debt investments in a current hypothetical sale using the Yield-to-Maturity valuation method and such Private Loan equity investments in a current hypothetical sale using the Waterfall valuation method.

        In addition to its internal valuation process, in arriving at estimates of fair value for its investments in its Private Loan portfolio companies, Main Street, among other things, consults with a nationally recognized independent financial advisory services firm. The nationally recognized independent financial advisory services firm analyzes and provides observations and recommendations and an assurance certification regarding the Company's determinations of the fair value of its Private Loan portfolio company investments. The nationally recognized independent financial advisory services firm is generally consulted relative to Main Street's investments in each Private Loan portfolio company at least once every calendar year, and for Main Street's investments in new Private Loan portfolio companies, at least once in the twelve-month period subsequent to the initial investment. In certain instances, Main Street may determine that it is not cost-effective, and as a result is not in its

stockholders' best interest, to consult with the nationally recognized independent financial advisory services firm on its investments in one or more Private Loan portfolio companies. Such instances include, but are not limited to, situations where the fair value of Main Street's investment in a Private Loan portfolio company is determined to be insignificant relative to the total Investment Portfolio. Main Street consulted with and received an assurance certification from its independent financial advisory services firm in arriving at its determination of fair value on its investments in a total of 21 Private Loan portfolio companies for the six months ended June 30, 2020, representing approximately 37% of the total Private Loan portfolio at fair value as of June 30, 2020, and on a total of 18 Private Loan portfolio companies for the six months ended June 30, 2019, representing approximately 31% of the total Private Loan portfolio at fair value as of June 30, 2019. Excluding its investments in Private Loan portfolio companies that, as of June 30, 2020 and 2019, as applicable, had not been in the Investment Portfolio for at least twelve months subsequent to the initial investment and its investments in Private Loan portfolio companies that were not reviewed because the investment is valued based upon third-party quotes or other independent pricing, the percentage of the Private Loan portfolio reviewed and certified by its independent financial advisory services firm for the six months ended June 30, 2020 and 2019 was 45% and 48% of the total Private Loan portfolio at fair value as of June 30, 2020 and 2019, respectively.

        For valuation purposes, all of Main Street's Other Portfolio investments are non-control investments. Main Street's Other Portfolio investments comprised 4.1% of Main Street's Investment Portfolio at fair value as of June 30, 2020 and December 31, 2019. Similar to the LMM investment portfolio, market quotations for Other Portfolio equity investments are generally not readily available. For its Other Portfolio equity investments, Main Street generally determines the fair value of these investments using the NAV valuation method.

        For valuation purposes, Main Street's investment in the External Investment Manager is a control investment. Market quotations are not readily available for this investment, and as a result, Main Street determines the fair value of the External Investment Manager using the Waterfall valuation method under the market approach. In estimating the enterprise value, Main Street analyzes various factors, including the entity's historical and projected financial results, as well as its size, marketability and performance relative to the population of market comparables. This valuation approach estimates the value of the investment as if Main Street were to sell, or exit, the investment. In addition, Main Street considers its ability to control the capital structure of the company, as well as the timing of a potential exit, in connection with determining the fair value of the External Investment Manager.

        Due to the inherent uncertainty in the valuation process, Main Street's determination of fair value for its Investment Portfolio may differ materially from the values that would have been determined had a ready market for the securities existed. In addition, changes in the market environment, portfolio company performance and other events that may occur over the lives of the investments may cause the gains or losses ultimately realized on these investments to be materially different than the valuations currently assigned. Main Street determines the fair value of each individual investment and records changes in fair value as unrealized appreciation or depreciation.

        Main Street uses an internally developed portfolio investment rating system in connection with its investment oversight, portfolio management and analysis and investment valuation procedures for its LMM portfolio companies. This system takes into account both quantitative and qualitative factors of the LMM portfolio company and the investments held therein.

        The Board of Directors of Main Street has the final responsibility for overseeing, reviewing and approving, in good faith, Main Street's determination of the fair value for its Investment Portfolio, as well as its valuation procedures, consistent with 1940 Act requirements. Main Street believes its Investment Portfolio as of June 30, 2020 and December 31, 2019 approximates fair value as of those dates based on the markets in which Main Street operates and other conditions in existence on those reporting dates.

2.     Use of Estimates

        The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Actual results may differ from these estimates under different conditions or assumptions. Additionally, as explained in Note B.1., the consolidated financial statements include investments in the Investment Portfolio whose values have been estimated by Main Street with the oversight, review and approval by Main Street's Board of Directors in the absence of readily ascertainable market values. Because of the inherent uncertainty of the Investment Portfolio valuations, those estimated values may differ materially from the values that would have been determined had a ready market for the securities existed.

        The COVID-19 pandemic, and the related effect on the U.S. and global economies, has impacted, and threatens to continue to impact, the businesses and operating results of certain of Main Street's portfolio companies, as well as market interest spreads. As a result of these and other current effects of the COVID-19 pandemic, as well as the uncertainty regarding the extent and duration of its impact, the valuation of Main Street's Investment Portfolio is volatile.

3.     Cash and Cash Equivalents

        Cash and cash equivalents consist of cash and highly liquid investments with an original maturity of three months or less at the date of purchase. Cash and cash equivalents are carried at cost, which approximates fair value.

        At June 30, 2020, cash balances totaling $65.4 million exceeded Federal Deposit Insurance Corporation insurance protection levels, subjecting the Company to risk related to the uninsured balance. All of the Company's cash deposits are held at large established high credit quality financial institutions and management believes that the risk of loss associated with any uninsured balances is remote.

4.     Interest, Dividend and Fee Income

        Main Street records interest and dividend income on the accrual basis to the extent amounts are expected to be collected. Dividend income is recorded as dividends are declared by the portfolio company or at the point an obligation exists for the portfolio company to make a distribution. In accordance with Main Street's valuation policies, Main Street evaluates accrued interest and dividend income periodically for collectability. When a loan or debt security becomes 90 days or more past due, and if Main Street otherwise does not expect the debtor to be able to service all of its debt or other obligations, Main Street will generally place the loan or debt security on non-accrual status and cease recognizing interest income on that loan or debt security until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a loan or debt security's status significantly

improves regarding the debtor's ability to service the debt or other obligations, or if a loan or debt security is sold or written off, Main Street removes it from non-accrual status.

        As of June 30, 2020, Main Street's total Investment Portfolio had eleven investments on non-accrual status, which comprised approximately 1.9% of its fair value and 6.3% of its cost. As of December 31, 2019, Main Street's total Investment Portfolio had eight investments on non-accrual status, which comprised approximately 1.4% of its fair value and 4.8% of its cost.

        Main Street holds certain debt and preferred equity instruments in its Investment Portfolio that contain payment-in-kind ("PIK") interest and cumulative dividend provisions. The PIK interest, computed at the contractual rate specified in each debt agreement, is periodically added to the principal balance of the debt and is recorded as interest income. Thus, the actual collection of this interest may be deferred until the time of debt principal repayment. Cumulative dividends are recorded as dividend income, and any dividends in arrears are added to the balance of the preferred equity investment. The actual collection of these dividends in arrears may be deferred until such time as the preferred equity is redeemed or sold. To maintain RIC tax treatment (as discussed in Note B.9. below), these non-cash sources of income may need to be paid out to stockholders in the form of distributions, even though Main Street may not have collected the PIK interest and cumulative dividends in cash. Main Street stops accruing PIK interest and cumulative dividends and writes off any accrued and uncollected interest and dividends in arrears when it determines that such PIK interest and dividends in arrears are no longer collectible. For the three months ended June 30, 2020 and 2019, (i) approximately 2.5% and 2.2%, respectively, of Main Street's total investment income was attributable to PIK interest income not paid currently in cash and (ii) approximately 0.9% and 1.1%, respectively, of Main Street's total investment income was attributable to cumulative dividend income not paid currently in cash. For the six months ended June 30, 2020 and 2019, (i) approximately 1.7% and 2.0%, respectively, of Main Street's total investment income was attributable to PIK interest income not paid currently in cash and (ii) approximately 0.9% and 1.1%, respectively, of Main Street's total investment income was attributable to cumulative dividend income not paid currently in cash.

        Main Street may periodically provide services, including structuring and advisory services, to its portfolio companies or other third parties. For services that are separately identifiable and evidence exists to substantiate fair value, fee income is recognized as earned, which is generally when the investment or other applicable transaction closes. Fees received in connection with debt financing transactions for services that do not meet these criteria are treated as debt origination fees and are deferred and accreted into income over the life of the financing.

        A presentation of total investment income Main Street received from its Investment Portfolio in each of the periods presented is as follows:

5.     Deferred Financing Costs

        Deferred financing costs include commitment fees and other costs related to Main Street's multi-year revolving credit facility (the "Credit Facility") and its unsecured notes, as well as the commitment fees and leverage fees (approximately 3.4% of the total commitment and draw amounts, as applicable) on the SBIC debentures which are not accounted for under the fair value option under ASC 825 (as discussed further in Note B.11.). See further discussion of Main Street's debt in Note E. Deferred financing costs in connection with the Credit Facility are capitalized as an asset. Deferred financing costs in connection with all other debt arrangements not using the fair value option are a direct deduction from the related debt liability.

6.     Equity Offering Costs

        The Company's offering costs are charged against the proceeds from equity offerings when the proceeds are received.

7.     Unearned Income—Debt Origination Fees and Original Issue Discount and Discounts / Premiums to Par Value

        Main Street capitalizes debt origination fees received in connection with financings and reflects such fees as unearned income netted against the applicable debt investments. The unearned income from the fees is accreted into income based on the effective interest method over the life of the financing.

        In connection with its portfolio debt investments, Main Street sometimes receives nominal cost warrants or warrants with an exercise price below the fair value of the underlying equity (together, "nominal cost equity") that are valued as part of the negotiation process with the particular portfolio company. When Main Street receives nominal cost equity, Main Street allocates its cost basis in its investment between its debt security and its nominal cost equity at the time of origination based on amounts negotiated with the particular portfolio company. The allocated amounts are based upon the fair value of the nominal cost equity, which is then used to determine the allocation of cost to the debt security. Any discount recorded on a debt investment resulting from this allocation is reflected as unearned income, which is netted against the applicable debt investment, and accreted into interest income based on the effective interest method over the life of the debt investment. The actual collection of this interest is deferred until the time of debt principal repayment.

        Main Street may also purchase debt securities at a discount or at a premium to the par value of the debt security. In the case of a purchase at a discount, Main Street records the investment at the par value of the debt security net of the discount, and the discount is accreted into interest income based on the effective interest method over the life of the debt investment. In the case of a purchase at a premium, Main Street records the investment at the par value of the debt security plus the premium, and the premium is amortized as a reduction to interest income based on the effective interest method over the life of the debt investment.

        To maintain RIC tax treatment (as discussed in Note B.9. below), these non-cash sources of income may need to be paid out to stockholders in the form of distributions, even though Main Street may not have collected the interest income. For the three months ended June 30, 2020 and 2019, approximately 2.6% and 2.5%, respectively, of Main Street's total investment income was attributable to interest income from the accretion of discounts associated with debt investments, net of any premium reduction. For the six months ended June 30, 2020 and 2019, approximately 2.6% and 2.7%, respectively, of Main Street's total investment income was attributable to interest income from the accretion of discounts associated with debt investments, net of any premium reduction.

8.     Share-Based Compensation

        Main Street accounts for its share-based compensation plans using the fair value method, as prescribed by ASC 718, Compensation—Stock Compensation. Accordingly, for restricted stock awards, Main Street measures the grant date fair value based upon the market price of its common stock on the date of the grant and amortizes the fair value of the awards as share-based compensation expense over the requisite service period, which is generally the vesting term.

        Main Street has also adopted Accounting Standards Update ("ASU") 2016-09, Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which requires that all excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) be recognized as income tax expense or benefit in the income statement and not delay recognition of a tax benefit until the tax benefit is realized through a reduction to taxes payable. Accordingly, the tax effects of exercised or vested awards are treated as discrete items in the reporting period in which they occur. Additionally, Main Street has elected to account for forfeitures as they occur.

9.     Income Taxes

        MSCC has elected to be treated for U.S. federal income tax purposes as a RIC. MSCC's taxable income includes the taxable income generated by MSCC and certain of its subsidiaries, including the Funds, which are treated as disregarded entities for tax purposes. As a RIC, MSCC generally will not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that MSCC distributes to its stockholders. MSCC must generally distribute at least 90% of its "investment company taxable income" (which is generally its net ordinary taxable income and realized net short-term capital gains in excess of realized net long-term capital losses) and 90% of its tax-exempt income to maintain its RIC status (pass-through tax treatment for amounts distributed). As part of maintaining RIC status, undistributed taxable income (subject to a 4% non-deductible U.S. federal excise tax) pertaining to a given fiscal year may be distributed up to 12 months subsequent to the end of that fiscal year, provided such dividends are declared on or prior to the later of (i) the filing of the U.S. federal income tax return for the applicable fiscal year or (ii) the fifteenth day of the ninth month following the close of the year in which such taxable income was generated.

        The Taxable Subsidiaries primarily hold certain portfolio investments for Main Street. The Taxable Subsidiaries permit Main Street to hold equity investments in portfolio companies which are "pass-through" entities for tax purposes and to continue to comply with the "source-of-income" requirements contained in the RIC tax provisions of the Code. The Taxable Subsidiaries are consolidated with Main Street for U.S. GAAP financial reporting purposes, and the portfolio investments held by the Taxable Subsidiaries are included in Main Street's consolidated financial statements as portfolio investments and recorded at fair value. The Taxable Subsidiaries are not consolidated with MSCC for income tax purposes and may generate income tax expense, or benefit, and tax assets and liabilities, as a result of their ownership of certain portfolio investments. The taxable income, or loss, of the Taxable Subsidiaries may differ from their book income, or loss, due to temporary book and tax timing differences and permanent differences. The Taxable Subsidiaries are each taxed at their normal corporate tax rates based on their taxable income. The income tax expense, or benefit, if any, and the related tax assets and liabilities, of the Taxable Subsidiaries are reflected in Main Street's consolidated financial statements.

        The External Investment Manager is an indirect wholly owned subsidiary of MSCC owned through a Taxable Subsidiary and is a disregarded entity for tax purposes. The External Investment Manager has entered into a tax sharing agreement with its Taxable Subsidiary owner. Since the External Investment Manager is accounted for as a portfolio investment of MSCC and is not included as a consolidated subsidiary of MSCC in MSCC's consolidated financial statements, and as a result of the tax sharing agreement with its Taxable Subsidiary owner, for its stand-alone financial reporting purposes the External Investment Manager is treated as if it is taxed at normal corporate tax rates based on its taxable income and, as a result of its activities, may generate income tax expense or benefit. The income tax expense, or benefit, if any, and the related tax assets and liabilities, of the External Investment Manager are reflected in the External Investment Manager's separate financial statements.

        The Taxable Subsidiaries and the External Investment Manager use the liability method in accounting for income taxes. Deferred tax assets and liabilities are recorded for temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements, using statutory tax rates in effect for the year in which the temporary differences are expected to reverse. A valuation allowance is provided, if necessary, against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized.

        Taxable income generally differs from net income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses. Taxable income generally excludes net unrealized appreciation or depreciation, as investment gains or losses are not included in taxable income until they are realized.

10.   Net Realized Gains or Losses and Net Unrealized Appreciation or Depreciation

        Realized gains or losses are measured by the difference between the net proceeds from the sale or redemption of an investment or a financial instrument and the cost basis of the investment or financial instrument, without regard to unrealized appreciation or depreciation previously recognized, and includes investments written-off during the period net of recoveries and realized gains or losses from in-kind redemptions. Net unrealized appreciation or depreciation reflects the net change in the fair value of the Investment Portfolio and financial instruments and the reclassification of any prior period unrealized appreciation or depreciation on exited investments and financial instruments to realized gains or losses.

11.   Fair Value of Financial Instruments

        Fair value estimates are made at discrete points in time based on relevant information. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Main Street believes that the carrying amounts of its financial instruments, consisting of cash and cash equivalents, receivables, payables and other liabilities approximate the fair values of such items due to the short-term nature of these instruments.

        As part of Main Street's acquisition of the majority of the equity interests of MSC II in January 2010 (the "MSC II Acquisition"), Main Street elected the fair value option under ASC 825, Financial Instruments ("ASC 825"), relating to accounting for debt obligations at their fair value, for the MSC II SBIC debentures acquired as part of the acquisition accounting related to the MSC II Acquisition and valued those obligations as discussed further in Note C. In order to provide for a more consistent basis of presentation, Main Street elected the fair value option for SBIC debentures issued by MSC II subsequent to the MSC II Acquisition. When the fair value option is elected for a given SBIC

debenture, the deferred loan costs associated with the debenture are fully expensed in the current period to "Net Unrealized Appreciation (Depreciation)—SBIC debentures" as part of the fair value adjustment. Interest incurred in connection with SBIC debentures which are valued at fair value is included in interest expense.

12.   Earnings per Share

        Basic and diluted per share calculations are computed utilizing the weighted-average number of shares of common stock outstanding for the period. In accordance with ASC 260, Earnings Per Share, the unvested shares of restricted stock awarded pursuant to Main Street's equity compensation plans are participating securities and, therefore, are included in the basic earnings per share calculation. As a result, for all periods presented, there is no difference between diluted earnings per share and basic earnings per share amounts.

13.   Recently Issued or Adopted Accounting Standards

        In August 2018, the SEC adopted rules (the "SEC Release") amending certain disclosure requirements intended to eliminate redundant, duplicative, overlapping, outdated, or superseded, in light of other SEC disclosure requirements, U.S. GAAP requirements or changes in the information environment. In part, the SEC Release requires an investment company to present distributable earnings in total on the consolidated balance sheet and consolidated statement of changes in net assets, rather than showing the three components of distributable earnings as previously shown. Main Street adopted this part of the SEC Release during the year ended December 31, 2018. The impact of the adoption of these rules on Main Street's consolidated financial statements was not material. Additionally, the SEC Release requires disclosure of changes in net assets within a registrant's Form 10-Q filings on a quarter-to-date and year-to-date basis for both the current year and prior year comparative periods. Main Street adopted the requirement to present changes in net assets in interim financial statements within Form 10-Q filings effective January 1, 2019. The adoption of these rules did not have a material impact on the consolidated financial statements.

        In March 2020, the FASB issued ASU 2020-04, "Reference rate reform (Topic 848)—Facilitation of the effects of reference rate reform on financial reporting." The amendments in this update provide optional expedients and exceptions for applying U.S. GAAP to certain contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform and became effective upon issuance for all entities. The Company has agreements that have LIBOR as a reference rate with certain portfolio companies and also with certain lenders. Many of these agreements include language for choosing an alternative successor rate if LIBOR reference is no longer considered to be appropriate. Contract modifications are required to be evaluated in determining whether the modifications result in the establishment of new contracts or the continuation of existing contracts. The Company adopted this amendment in March 2020 and plans to apply the amendments in this update to account for contract modifications due to changes in reference rates. The Company does not believe that it will have a material impact on its consolidated financial statements and disclosures.

        In May 2020, the SEC adopted rules Release No. 33-10786 (the "Release"), Amendments to Financial Disclosures about Acquired and Disposed Businesses, amending Rule 1-02(w)(2) used in the determination of a significant subsidiary. In part, the Release eliminated the use of the asset test, and amended the income and investment tests for determining whether an unconsolidated subsidiary

requires additional disclosure in the footnotes of the financial statements. Main Street adopted the Release during the quarter ended June 30, 2020. The impact of the adoption of these rules on Main Street's consolidated financial statements was not material.

        From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that are adopted by Main Street as of the specified effective date. Main Street believes that the impact of recently issued standards and any that are not yet effective will not have a material impact on its consolidated financial statements upon adoption.

NOTE C—FAIR VALUE HIERARCHY FOR INVESTMENTS AND DEBENTURES—PORTFOLIO COMPOSITION

        ASC 820 defines fair value, establishes a framework for measuring fair value, establishes a fair value hierarchy based on the quality of inputs used to measure fair value, and enhances disclosure requirements for fair value measurements. Main Street accounts for its investments at fair value.

    Fair Value Hierarchy

        In accordance with ASC 820, Main Street has categorized its investments based on the priority of the inputs to the valuation technique into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical investments (Level 1) and the lowest priority to unobservable inputs (Level 3).

        Investments recorded on Main Street's balance sheet are categorized based on the inputs to the valuation techniques as follows:

            Level 1—Investments whose values are based on unadjusted quoted prices for identical assets in an active market that Main Street has the ability to access (examples include investments in active exchange-traded equity securities and investments in most U.S. government and agency securities).

            Level 2—Investments whose values are based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the investment. Level 2 inputs include the following:

      Quoted prices for similar assets in active markets (for example, investments in restricted stock);

      Quoted prices for identical or similar assets in non-active markets (for example, investments in thinly traded public companies);

      Pricing models whose inputs are observable for substantially the full term of the investment (for example, market interest rate indices); and

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

            Level 3—Investments whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement (for example, investments in illiquid securities issued by privately held companies). These inputs reflect

    management's own assumptions about the assumptions a market participant would use in pricing the investment.

        As required by ASC 820, when the inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement in its entirety. For example, a Level 3 fair value measurement may include inputs that are observable (Levels 1 and 2) and unobservable (Level 3). Therefore, unrealized appreciation and depreciation related to such investments categorized within the Level 3 tables below may include changes in fair value that are attributable to both observable inputs (Levels 1 and 2) and unobservable inputs (Level 3).

        As of June 30, 2020 and December 31, 2019, all of Main Street's LMM portfolio investments consisted of illiquid securities issued by privately held companies and the fair value determination for these investments primarily consisted of unobservable inputs. As a result, all of Main Street's LMM portfolio investments were categorized as Level 3 as of June 30, 2020 and December 31, 2019.

        As of June 30, 2020 and December 31, 2019, Main Street's Middle Market portfolio investments consisted primarily of investments in secured and unsecured debt investments and independently rated debt investments. The fair value determination for these investments consisted of a combination of observable inputs in non-active markets for which sufficient observable inputs were not available to determine the fair value of these investments and unobservable inputs. As a result, all of Main Street's Middle Market portfolio investments were categorized as Level 3 as of June 30, 2020 and December 31, 2019.

        As of June 30, 2020 and December 31, 2019, Main Street's Private Loan portfolio investments primarily consisted of investments in interest-bearing secured debt investments. The fair value determination for these investments consisted of a combination of observable inputs in non-active markets for which sufficient observable inputs were not available to determine the fair value of these investments and unobservable inputs. As a result, all of Main Street's Private Loan portfolio investments were categorized as Level 3 as of June 30, 2020 and December 31, 2019.

        As of June 30, 2020 and December 31, 2019, Main Street's Other Portfolio investments consisted of illiquid securities issued by privately held companies and the fair value determination for these investments primarily consisted of unobservable inputs. As a result, all of Main Street's Other Portfolio investments were categorized as Level 3 as of June 30, 2020 and December 31, 2019.

        The fair value determination of each portfolio investment categorized as Level 3 required one or more of the following unobservable inputs:

    Financial information obtained from each portfolio company, including unaudited statements of operations and balance sheets for the most recent period available as compared to budgeted numbers;

    Current and projected financial condition of the portfolio company;

    Current and projected ability of the portfolio company to service its debt obligations;

    Type and amount of collateral, if any, underlying the investment;

    Current financial ratios (e.g., fixed charge coverage ratio, interest coverage ratio and net debt/EBITDA ratio) applicable to the investment;

70

Notes to Consolidated Financial Statements (Continued)

(Unaudited)

    Current liquidity of the investment and related financial ratios (e.g., current ratio and quick ratio);

    Pending debt or capital restructuring of the portfolio company;

    Projected operating results of the portfolio company;

    Current information regarding any offers to purchase the investment;

    Current ability of the portfolio company to raise any additional financing as needed;

    Changes in the economic environment which may have a material impact on the operating results of the portfolio company;

    Internal occurrences that may have an impact (both positive and negative) on the operating performance of the portfolio company;

    Qualitative assessment of key management;

    Contractual rights, obligations or restrictions associated with the investment; and

    Other factors deemed relevant.

        The use of significant unobservable inputs creates uncertainty in the measurement of fair value as of the reporting date. The significant unobservable inputs used in the fair value measurement of Main Street's LMM equity securities, which are generally valued through an average of the discounted cash flow technique and the market comparable/enterprise value technique (unless one of these approaches is determined to not be appropriate), are (i) EBITDA multiples and (ii) the weighted-average cost of capital ("WACC"). Significant increases (decreases) in EBITDA multiple inputs in isolation would result in a significantly higher (lower) fair value measurement. On the contrary, significant increases (decreases) in WACC inputs in isolation would result in a significantly lower (higher) fair value measurement. The significant unobservable inputs used in the fair value measurement of Main Street's LMM, Middle Market and Private Loan securities are (i) risk adjusted discount rates used in the Yield-to-Maturity valuation technique (see "Note B.1.—Valuation of the Investment Portfolio") and (ii) the percentage of expected principal recovery. Significant increases (decreases) in any of these discount rates in isolation would result in a significantly lower (higher) fair value measurement. Significant increases (decreases) in any of these expected principal recovery percentages in isolation would result in a significantly higher (lower) fair value measurement. However, due to the nature of certain investments, fair value measurements may be based on other criteria, such as third-party appraisals of collateral and fair values as determined by independent third parties, which are not presented in the tables below.

        As of December 31, 2019, the fair value determination for the SBIC debentures recorded at fair value primarily consisted of unobservable inputs. As a result, the SBIC debentures which were recorded at fair value were categorized as Level 3. Main Street determined the fair value of these instruments primarily using a Yield-to-Maturity approach that analyzed the discounted cash flows of interest and principal for each SBIC debenture recorded at fair value based on estimated market interest rates for debt instruments of similar structure, terms, and maturity. Main Street's estimate of the expected repayment date of principal for each SBIC debenture recorded at fair value was the legal maturity date of the instrument. The significant unobservable inputs used in the fair value measurement of Main Street's SBIC debentures recorded at fair value were the estimated market interest rates used to fair value each debenture using the yield valuation technique described above. As of June 30, 2020, all of the SBIC debentures previously accounted for on a fair value basis have been repaid.

Investment Portfolio Composition

        Main Street's LMM portfolio investments primarily consist of secured debt, equity warrants and direct equity investments in privately held, LMM companies based in the United States. Main Street's LMM portfolio companies generally have annual revenues between $10 million and $150 million, and its LMM investments generally range in size from $5 million to $50 million. The LMM debt investments are typically secured by either a first or second priority lien on the assets of the portfolio company, can include either fixed or floating rate terms and generally have a term of between five and

(Unaudited)

seven years from the original investment date. In most LMM portfolio investments, Main Street receives nominally priced equity warrants and/or makes direct equity investments in connection with a debt investment.

        Main Street's Middle Market portfolio investments primarily consist of direct investments in or secondary purchases of interest-bearing debt securities in privately held companies based in the United States that are generally larger in size than the companies included in Main Street's LMM portfolio. Main Street's Middle Market portfolio companies generally have annual revenues between $150 million and $1.5 billion, and its Middle Market investments generally range in size from $3 million to $20 million. Main Street's Middle Market portfolio debt investments are generally secured by either a first or second priority lien on the assets of the portfolio company and typically have a term of between three and seven years from the original investment date.

        Main Street's Private Loan portfolio investments are primarily debt securities in privately held companies which have been originated through strategic relationships with other investment funds on a collaborative basis, and are often referred to in the debt markets as "club deals." Private Loan investments are typically similar in size, structure, terms and conditions to investments Main Street holds in its LMM portfolio and Middle Market portfolio. Main Street's Private Loan portfolio debt investments are generally secured by either a first or second priority lien on the assets of the portfolio company and typically have a term of between three and seven years from the original investment date.

        Main Street's Other Portfolio investments primarily consist of investments which are not consistent with the typical profiles for LMM, Middle Market and Private Loan portfolio investments, including investments which may be managed by third parties. In the Other Portfolio, Main Street may incur indirect fees and expenses in connection with investments managed by third parties, such as investments in other investment companies or private funds. For Other Portfolio investments, Main Street generally receives distributions related to the assets held by the portfolio company. Those assets are typically expected to be liquidated over a five to ten-year period.

        Main Street's external asset management business is conducted through its External Investment Manager. The External Investment Manager earns management fees based on the assets of the funds under management and may earn incentive fees, or a carried interest, based on the performance of the funds managed. Main Street entered into an agreement with the External Investment Manager to share employees in connection with its asset management business generally, and specifically for its relationship with HMS Income Fund, Inc. ("HMS Income"). Through this agreement, Main Street shares employees with the External Investment Manager, including their related infrastructure, business relationships, management expertise and capital raising capabilities. Main Street allocates the related expenses to the External Investment Manager pursuant to the sharing agreement. Main Street's total expenses for the three months ended June 30, 2020 and 2019 are net of expenses allocated to the External Investment Manager of $1.8 million and $1.7 million, respectively. Main Street's total expenses for each of the six months ended June 30, 2020 and 2019 are net of expenses allocated to the External Investment Manager of $3.4 million.

        Investment income, consisting of interest, dividends and fees, can fluctuate dramatically due to various factors, including the level of new investment activity, repayments of debt investments or sales of equity interests. Investment income in any given year could also be highly concentrated among several portfolio companies. For the three and six months ended June 30, 2020 and 2019, Main Street did not record investment income from any single portfolio company in excess of 10% of total investment income.

The weighted-average annual effective yields were computed using the effective interest rates for all debt investments at cost as of June 30, 2020, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt instruments and any debt investments on non-accrual status. The weighted-average annual effective yield is higher than what an investor in shares of Main Street's common stock will realize on its investment because it does not reflect Main Street's expenses or any sales load paid by an investor.

(c)
The average EBITDA is calculated using a simple average for the LMM portfolio and a weighted-average for the Middle Market and Private Loan portfolios. These calculations exclude certain portfolio companies, including two LMM portfolio companies, two Middle Market portfolio companies and four Private Loan portfolio companies, as EBITDA is not a meaningful valuation metric for Main Street's investments in these portfolio companies, and those portfolio companies whose primary purpose is to own real estate.

The average EBITDA is calculated using a simple average for the LMM portfolio and a weighted-average for the Middle Market and Private Loan portfolios. These calculations exclude certain portfolio companies, including three LMM portfolio companies, two Middle Market portfolio companies and three Private Loan portfolio companies, as EBITDA is not a meaningful valuation metric for Main Street's investments in these portfolio companies, and those portfolio companies whose primary purpose is to own real estate.

        As of June 30, 2020, Main Street had Other Portfolio investments in twelve companies, collectively totaling approximately $98.1 million in fair value and approximately $126.4 million in cost basis and which comprised approximately 4.1% of Main Street's Investment Portfolio at fair value.

Unconsolidated Significant Subsidiaries

        In accordance with Rules 3-09 and 4-08(g) of Regulation S-X, Main Street must determine which of its unconsolidated controlled portfolio companies, if any, are considered "significant subsidiaries." On May 20, 2020, the SEC published in Release No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, amendments to Rule 1-02(w)(2) of Regulation S-X used in the determination of a significant subsidiary specific to investment companies, including BDCs. The amendments become effective on January 1, 2021, but the SEC allowed for early application. Main Street elected to apply these revisions effective June 30, 2020. In evaluating its unconsolidated controlled portfolio companies in accordance with the revised rules, there are two tests that Main Street must utilize to determine if any of Main Street's Control Investments (as defined in Note A, including those unconsolidated portfolio companies defined as Control Investments in which Main Street does not own greater than 50% of the voting securities or maintain greater than 50% of the board representation) are considered significant subsidiaries: the investment test and the income test. The investment test is generally measured by dividing Main Street's investment in the Control Investment by the value of Main Street's total assets. The income test is measured by dividing the absolute value of the combined total of total investment income, net realized gain (loss) and net unrealized appreciation (depreciation) from the relevant Control Investment for the period being tested by the absolute value of Main Street's change in net assets resulting from operations for the same period. Rules 3-09 and 4-08(g) of Regulation S-X, as interpreted by the SEC, require Main Street to include (1) separate audited financial statements of an unconsolidated majority-owned subsidiary (Control Investments in which Main Street owns greater than 50% of the voting securities) in an annual report and (2) summarized financial information of a Control Investment in a quarterly report, respectively, if certain thresholds of the investment or income tests are exceeded and the unconsolidated portfolio company qualifies as a significant subsidiary.

        As of June 30, 2020 and December 31, 2019, Main Street had no single investment that qualified as a significant subsidiary under either the investment or income tests.

NOTE D—EXTERNAL INVESTMENT MANAGER

        As discussed further in Note A.1., the External Investment Manager provides investment management and other services to External Parties. The External Investment Manager is accounted for as a portfolio investment of MSCC since the External Investment Manager conducts all of its investment management activities for External Parties.

        During May 2012, Main Street entered into an investment sub-advisory agreement with HMS Adviser, LP ("HMS Adviser"), which is the investment advisor to HMS Income, a non-listed BDC, to provide certain investment advisory services to HMS Adviser. In December 2013, after obtaining required no-action relief from the SEC to allow it to own a registered investment adviser, Main Street assigned the sub-advisory agreement to the External Investment Manager since the fees received from such arrangement could otherwise have negative consequences on MSCC's ability to meet the source-of-income requirement necessary for it to maintain its RIC tax treatment. Under the investment sub-advisory agreement, the External Investment Manager is entitled to 50% of the base management fee and the incentive fees earned by HMS Adviser under its advisory agreement with HMS Income. During the three months ended June 30, 2020 and 2019, the External Investment Manager earned $2.3 million and $4.1 million, respectively, in base management fee income. No incentive fee income was earned in the three months ended June 30, 2020 compared to $1.3 million earned in the three

NOTE D—EXTERNAL INVESTMENT MANAGER (Continued)

months ended June 30, 2019. During the six months ended June 30, 2020, the External Investment Manager earned $4.8 million in base management fee income and no incentive fees compared to $5.7 million of base management fees and $1.4 million in incentive fees for the comparable period in 2019 under the sub-advisory agreement with HMS Adviser.

        The investment in the External Investment Manager is accounted for using fair value accounting, with the fair value determined by Main Street and approved, in good faith, by Main Street's Board of Directors. Main Street determines the fair value of the External Investment Manager using the Waterfall valuation method under the market approach (see further discussion in Note B.1.). Any change in fair value of the investment in the External Investment Manager is recognized on Main Street's consolidated statements of operations in "Net Unrealized Appreciation (Depreciation)—Control investments."

        The External Investment Manager is an indirect wholly owned subsidiary of MSCC owned through a Taxable Subsidiary and is a disregarded entity for tax purposes. The External Investment Manager has entered into a tax sharing agreement with its Taxable Subsidiary owner. Since the External Investment Manager is accounted for as a portfolio investment of MSCC and is not included as a consolidated subsidiary of MSCC in MSCC's consolidated financial statements, and as a result of the tax sharing agreement with its Taxable Subsidiary owner, for financial reporting purposes the External Investment Manager is treated as if it is taxed at normal corporate tax rates based on its taxable income and, as a result of its activities, may generate income tax expense or benefit. Main Street owns the External Investment Manager through the Taxable Subsidiary to allow MSCC to continue to comply with the "source-of-income" requirements contained in the RIC tax provisions of the Code. The taxable income, or loss, of the External Investment Manager may differ from its book income, or loss, due to temporary book and tax timing differences and permanent differences. As a result of the above described financial reporting and tax treatment, the External Investment Manager provides for any income tax expense, or benefit, and any tax assets or liabilities in its separate financial statements.

        Main Street shares employees with the External Investment Manager and allocates costs related to such shared employees to the External Investment Manager generally based on a combination of the direct time spent, new investment origination activity and assets under management, depending on the nature of the expense. For the three months ended June 30, 2020 and 2019, Main Street allocated $1.8 million and $1.7 million of total expenses, respectively, to the External Investment Manager. For each of the six months ended June 30, 2020 and 2019, Main Street allocated $3.4 million of total expenses to the External Investment Manager. The total contribution of the External Investment Manager to Main Street's net investment income consists of the combination of the expenses allocated to the External Investment Manager and the dividend income earned from the External Investment Manager. For the three months ended June 30, 2020 and 2019, the total contribution to Main Street's net investment income was $2.2 million and $3.6 million, respectively. For the six months ended June 30, 2020, and 2019, the total contribution to Main Street's net investment income was $4.5 million and $6.2 million, respectively.

NOTE E—DEBT

SBIC Debentures

        Under existing SBIC regulations, SBA-approved SBICs under common control have the ability to issue debentures guaranteed by the SBA up to a regulatory maximum amount of $350.0 million. Main Street's SBIC debentures payable, under existing SBA-approved commitments, were $314.8 million and $311.8 million at June 30, 2020 and December 31, 2019, respectively. SBIC debentures provide for interest to be paid semiannually, with principal due at the applicable 10-year maturity date of each debenture. During the six months ended June 30, 2020, Main Street issued $25.0 million of SBIC debentures and opportunistically prepaid the remaining $22.0 million of existing MSC II SBIC debentures. As a result of this prepayment, Main Street recognized a realized loss of $0.5 million, due

primarily to the write-off of the related unamortized deferred financing costs. Main Street expects to issue new SBIC debentures under the SBIC program in the future in an amount up to the regulatory maximum amount for affiliated SBIC funds. The weighted-average annual interest rate on the SBIC debentures was 3.5% and 3.6% as of June 30, 2020 and December 31, 2019, respectively. The first principal maturity due under the existing SBIC debentures is in 2020, and the weighted-average remaining duration as of June 30, 2020 was approximately 5.3 years. For the three months ended June 30, 2020 and 2019, Main Street recognized interest expense, including the amortization of upfront leverage and other miscellaneous fees, attributable to the SBIC debentures of $3.0 million and $3.2 million, respectively. For the six months ended June 30, 2020 and 2019, Main Street recognized interest expense, including the amortization of upfront leverage and other miscellaneous fees, attributable to the SBIC debentures of $6.0 million and $6.5 million, respectively. In accordance with SBIC regulations, the Funds are precluded from incurring additional non-SBIC debt without the prior approval of the SBA.

        As of June 30, 2020, the recorded value of the SBIC debentures was $308.8 million, which consisted of (i) $139.8 million par value of SBIC debentures outstanding issued by MSMF, with a recorded value of $138.4 million that was net of unamortized debt issuance costs of $1.4 million and (ii) $175.0 million par value of SBIC debentures issued by MSC III with a recorded value of $170.4 million that was net of unamortized debt issuance costs of $4.6 million. As of June 30, 2020, if Main Street had adopted the fair value option under ASC 825 for its SBIC debentures, Main Street estimates the fair value of its SBIC debentures would be approximately $290.1 million, or $24.7 million less than the $314.8 million face value of the SBIC debentures.

Credit Facility

        Main Street maintains the Credit Facility to provide additional liquidity to support its investment and operational activities. The Credit Facility includes total commitments of $740.0 million from a diversified group of 18 lenders. The Credit Facility matures in September 2023 and contains an accordion feature which allows Main Street to increase the total commitments under the facility to up to $800.0 million from new and existing lenders on the same terms and conditions as the existing commitments.

        Borrowings under the Credit Facility bear interest, subject to Main Street's election and resetting on a monthly basis on the first of each month, on a per annum basis at a rate equal to the applicable LIBOR rate (0.2% as of June 30, 2020) plus (i) 1.875% (or the applicable base rate (Prime Rate of 3.25% as of June 30, 2020) plus 0.875%) as long as Main Street meets certain agreed upon excess collateral and maximum leverage requirements or (ii) 2.0% (or the applicable base rate plus 1.0%) otherwise. Main Street pays unused commitment fees of 0.25% per annum on the unused lender commitments under the Credit Facility. The Credit Facility is secured by a first lien on the assets of MSCC and its subsidiaries, excluding the equity ownership or assets of the Funds and the External Investment Manager. The Credit Facility contains certain affirmative and negative covenants, including but not limited to: (i) maintaining a minimum availability of at least 10% of the borrowing base, (ii) maintaining an interest coverage ratio of at least 2.0 to 1.0, (iii) maintaining an asset coverage ratio (tangible net worth to Credit Facility borrowings) of at least 1.5 to 1.0 and (iv) maintaining a minimum tangible net worth. The Credit Facility is provided on a revolving basis through its final maturity date in September 2023, and contains two, one-year extension options which could extend the final maturity by up to two years, subject to certain conditions, including lender approval.

        At June 30, 2020, Main Street had $315.0 million in borrowings outstanding under the Credit Facility. As of June 30, 2020, if Main Street had adopted the fair value option under ASC 825 for its Credit Facility, Main Street estimates its fair value would approximate its recorded value. Main Street recognized interest expense related to the Credit Facility, including unused commitment fees and amortization of deferred issuance costs, of $2.4 million and $2.2 million for the three months ended June 30, 2020 and 2019, respectively, and $5.4 million and $6.4 million for the six months ended June 30, 2020 and 2019, respectively. As of June 30, 2020, the interest rate on the Credit Facility was 2.0% (based on the LIBOR rate of 0.2% as of the most recent reset date plus 1.875%). The average interest rate for borrowings under the Credit Facility was 2.4% and 4.4% for the three months ended June 30, 2020 and 2019, respectively, and 3.0% and 4.4%, for the six months ended June, 2020 and 2019, respectively. As of June 30, 2020, Main Street was in compliance with all financial covenants of the Credit Facility.

4.50% Notes due 2019

        In November 2014, Main Street issued $175.0 million in aggregate principal amount of 4.50% unsecured notes due 2019 (the "4.50% Notes due 2019") at an issue price of 99.53%. The 4.50% Notes due 2019 bore interest at a rate of 4.50% per year payable semiannually on June 1 and December 1 of each year. On December 2, 2019, Main Street repaid the entire principal amount of the issued and outstanding 4.50% Notes due 2019, effective December 1, 2019 (the "Maturity Date"), at par value plus the accrued and unpaid interest thereon from June 1, 2019 through the Maturity Date. Main Street recognized no interest expense related to the 4.50% Notes due 2019, including amortization of unamortized deferred issuance costs, for the three and six months ended June 30, 2020 and $2.1 million and $4.3 million for the three and six months ended June 30, 2019, respectively.

4.50% Notes due 2022

        In November 2017, Main Street issued $185.0 million in aggregate principal amount of 4.50% unsecured notes due December 1, 2022 (the "4.50% Notes due 2022") at an issue price of 99.16%. The 4.50% Notes due 2022 are unsecured obligations and rank pari passu with Main Street's current and future unsecured indebtedness; senior to any of its future indebtedness that expressly provides it is subordinated to the 4.50% Notes due 2022; effectively subordinated to all of its existing and future secured indebtedness, to the extent of the value of the assets securing such indebtedness, including borrowings under its Credit Facility; and structurally subordinated to all existing and future indebtedness and other obligations of any of its subsidiaries, including without limitation, the indebtedness of the Funds. The 4.50% Notes due 2022 may be redeemed in whole or in part at any time at Main Street's option subject to certain make-whole provisions. The 4.50% Notes due 2022 bear interest at a rate of 4.50% per year payable semiannually on June 1 and December 1 of each year. The total net proceeds from the 4.50% Notes due 2022, resulting from the issue price and after underwriting discounts and estimated offering expenses payable, were approximately $182.2 million. Main Street may from time to time repurchase the 4.50% Notes due 2022 in accordance with the 1940 Act and the rules promulgated thereunder. As of June 30, 2020, the outstanding balance of the 4.50% Notes due 2022 was $185.0 million and the recorded value of $183.5 million was net of unamortized debt issuance costs of $1.5 million. As of June 30, 2020, if Main Street had adopted the fair value option under ASC 825 for the 4.50% Notes due 2022, Main Street estimates its fair value would be approximately $187.1 million. Main Street recognized interest expense related to the 4.50% Notes due 2022, including amortization of unamortized deferred issuance costs, of $2.2 million for each of the

three months ended June 30, 2020 and 2019 and $4.5 million for each of the six months ended June 30, 2020 and 2019.

        The indenture governing the 4.50% Notes due 2022 (the "4.50% Notes due 2022 Indenture") contains certain covenants, including covenants requiring Main Street's compliance with (regardless of whether Main Street is subject to) the asset coverage requirements set forth in Section 18(a)(1)(A) as modified by Section 61(a)(1) of the 1940 Act, as well as covenants requiring Main Street to provide financial information to the holders of the 4.50% Notes due 2022 and the Trustee if Main Street ceases to be subject to the reporting requirements of the Exchange Act. These covenants are subject to limitations and exceptions that are described in the 4.50% Notes due 2022 Indenture. As of June 30, 2020, Main Street was in compliance with these covenants.

5.20% Notes

        In April 2019, Main Street issued $250.0 million in aggregate principal amount of 5.20% unsecured notes due May 1, 2024 (the "5.20% Notes") at an issue price of 99.125%. Subsequently, in December 2019, Main Street issued an additional $75.0 million of the 5.20% Notes at an issue price of 105.0%. The 5.20% Notes issued in December 2019 have identical terms as, and are a part of a single series with, the 5.20% Notes issued in April 2019. The 5.20% Notes are unsecured obligations and rank pari passu with Main Street's current and future unsecured indebtedness; senior to any of its future indebtedness that expressly provides it is subordinated to the 5.20% Notes; effectively subordinated to all of its existing and future secured indebtedness, to the extent of the value of the assets securing such indebtedness, including borrowings under its Credit Facility; and structurally subordinated to all existing and future indebtedness and other obligations of any of its subsidiaries, including without limitation, the indebtedness of the Funds. The 5.20% Notes may be redeemed in whole or in part at any time at Main Street's option subject to certain make-whole provisions. The 5.20% Notes bear interest at a rate of 5.20% per year payable semiannually on May 1 and November 1 of each year. The total net proceeds from the 5.20% Notes, resulting from the issue price and after underwriting discounts and estimated offering expenses payable, were approximately $324.1 million. Main Street may from time to time repurchase the 5.20% Notes in accordance with the 1940 Act and the rules promulgated thereunder. As of June 30, 2020, the outstanding balance of the 5.20% Notes was $325.0 million and the recorded value of $324.5 million was net of unamortized debt issuance costs of $0.5 million. As of June 30, 2020, if Main Street had adopted the fair value option under ASC 825 for the 5.20% Notes, Main Street estimates its fair value would be approximately $332.8 million. Main Street recognized interest expense related to the 5.20% Notes, including amortization of unamortized deferred issuance costs, of $4.3 million and $2.6 million for the three months ended June 30, 2020 and 2019, respectively, and $8.5 million and $2.6 million for the six months ended June 30, 2020 and 2019, respectively.

        The indenture governing the 5.20% Notes (the "5.20% Notes Indenture") contains certain covenants, including covenants requiring Main Street's compliance with (regardless of whether Main Street is subject to) the asset coverage requirements set forth in Section 18(a)(1)(A) as modified by Section 61(a)(1) of the 1940 Act, as well as covenants requiring Main Street to provide financial information to the holders of the 5.20% Notes and the Trustee if Main Street ceases to be subject to the reporting requirements of the Exchange Act. These covenants are subject to limitations and exceptions that are described in the 5.20% Notes Indenture. As of June 30, 2020, Main Street was in compliance with these covenants.

NOTE G—DIVIDENDS, DISTRIBUTIONS AND TAXABLE INCOME

        Main Street paid regular monthly dividends of $0.205 per share for each month of January through June 2020, totaling $39.9 million, or $0.615 per share, for the three months ended June 30, 2020, and $79.6 million, or $1.230 per share, for the six months ended June 30, 2020 compared to regular monthly dividends of approximately $37.6 million, or $0.60 per share, for the three months ended June 30, 2019, and $73.7 million, or $1.185 per share, for the six months ended June 30, 2019. The second quarter 2020 regular monthly dividends represent a 2.5% increase from the regularly monthly dividends paid for the second quarter of 2019. Additionally, Main Street paid a $0.250 per share semi-annual supplemental dividend, totaling $15.8 million, in June 2019. Total dividends paid for the six months ended June 30, 2020 and 2019 equaled $1.230 and $1.435 per share, respectively.

        MSCC has elected to be treated for U.S. federal income tax purposes as a RIC. MSCC's taxable income includes the taxable income generated by MSCC and certain of its subsidiaries, including the Funds, which are treated as disregarded entities for tax purposes. As a RIC, MSCC generally will not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that MSCC distributes to its stockholders. MSCC must generally distribute at least 90% of its "investment company taxable income" (which is generally its net ordinary taxable income and realized net short-term capital gains in excess of realized net long-term capital losses) and 90% of its tax-exempt income to maintain its RIC status (pass-through tax treatment for amounts distributed). As part of maintaining RIC status, undistributed taxable income (subject to a 4% non-deductible U.S. federal excise tax) pertaining to a given fiscal year may be distributed up to 12 months subsequent to the end of that fiscal year, provided such dividends are declared on or prior to the later of (i) filing of the U.S. federal income tax return for the applicable fiscal year or (ii) the fifteenth day of the ninth month following the close of the year in which such taxable income was generated.

        The determination of the tax attributes for Main Street's distributions is made annually, based upon its taxable income for the full year and distributions paid for the full year. Therefore, a determination made on an interim basis may not be representative of the actual tax attributes of distributions for a full year. Ordinary dividend distributions from a RIC do not qualify for the 20% maximum tax rate (plus a 3.8% Medicare surtax, if applicable) on dividend income from domestic corporations and qualified foreign corporations, except to the extent that the RIC received the income in the form of qualifying dividends from domestic corporations and qualified foreign corporations. The tax attributes for distributions will generally include both ordinary income and qualified dividends, but may also include either one or both of capital gains and return of capital.

        Listed below is a reconciliation of "Net increase (decrease) in net assets resulting from operations" to taxable income and to total distributions declared to common stockholders for the six months ended June 30, 2020 and 2019.

Main Street's taxable income for each period is an estimate and will not be finally determined until the company files its tax return for each year. Therefore, the final taxable income, and the taxable income earned in each period and carried forward for distribution in the following period, may be different than this estimate.

        The Taxable Subsidiaries primarily hold certain portfolio investments for Main Street. The Taxable Subsidiaries permit Main Street to hold equity investments in portfolio companies which are "pass-through" entities for tax purposes and to continue to comply with the "source-of-income" requirements contained in the RIC tax provisions of the Code. The Taxable Subsidiaries are consolidated with Main Street for U.S. GAAP financial reporting purposes, and the portfolio investments held by the Taxable Subsidiaries are included in Main Street's consolidated financial

statements as portfolio investments and recorded at fair value. The Taxable Subsidiaries are not consolidated with MSCC for income tax purposes and may generate income tax expense, or benefit, and tax assets and liabilities, as a result of their ownership of certain portfolio investments. The taxable income, or loss, of the Taxable Subsidiaries may differ from their book income, or loss, due to temporary book and tax timing differences and permanent differences. The Taxable Subsidiaries are each taxed at their normal corporate tax rates based on their taxable income. The income tax expense, or benefit, if any, and the related tax assets and liabilities, of the Taxable Subsidiaries are reflected in Main Street's consolidated financial statements.

        The income tax provision (benefit) for Main Street is generally composed of (i) deferred tax expense (benefit), which is primarily the result of the net activity relating to the portfolio investments held in the Taxable Subsidiaries, including changes in loss carryforwards, changes in net unrealized appreciation or depreciation and other temporary book tax differences, and (ii) current tax expense, which is primarily the result of current U.S. federal income and state taxes and excise taxes on Main Street's estimated undistributed taxable income. For the three months ended June 30, 2020, Main Street recognized a net income tax benefit of $7.5 million, principally consisting of a deferred tax benefit of $8.0 million, partially offset by a $0.6 million current tax provision, which is primarily related to a $0.4 million provision for current U.S. federal income and state taxes, as well as a $0.2 million provision for excise taxes. For the six months ended June 30, 2020, Main Street recognized a net income tax benefit of $15.8 million, principally consisting of a deferred tax benefit of $16.0 million, partially offset by a $0.3 million current tax expense, which is primarily related to a $0.7 million provision for excise taxes, partially offset by a $0.4 million benefit for current U.S. federal income and state taxes. For the three months ended June 30, 2019, Main Street recognized a net income tax provision of $3.4 million, principally consisting of a deferred tax provision of $2.5 million and a $0.9 million current tax expense, which is primarily related to current U.S. federal income and state taxes. For the six months ended June 30, 2019, Main Street recognized a net income tax provision of $6.5 million, principally consisting of a deferred tax provision of $4.8 million and a $1.7 million current tax expense, which is primarily related to a $1.3 million provision for current U.S. federal income and state taxes and a $0.4 million accrual for excise taxes.

        The net deferred tax liability at June 30, 2020 was $0.4 million compared to $16.1 million at December 31, 2019, primarily related to changes in net unrealized appreciation or depreciation, changes in loss carryforwards, and other temporary book-tax differences relating to portfolio investments held by the Taxable Subsidiaries. At June 30, 2020, for U.S. federal income tax purposes, the Taxable Subsidiaries had a net operating loss carryforward from prior years which, if unused, will expire in various taxable years from 2029 through 2037. Any net operating losses generated in 2019 and future periods are not subject to expiration and will carryforward indefinitely until utilized. The timing and manner in which Main Street will utilize any loss carryforwards generated before December 31, 2019 may be limited in the future under the provisions of the Code. Additionally, the Taxable Subsidiaries have interest expense limitation carryforwards which have an indefinite carryforward.

NOTE H—COMMON STOCK

        Main Street maintains a program with certain selling agents through which it can sell shares of its common stock by means of at-the-market offerings from time to time (the "ATM Program"). During the six months ended June 30, 2020, Main Street sold 907,515 shares of its common stock at a weighted-average price of $33.06 per share and raised $30.0 million of gross proceeds under the ATM Program. Net proceeds were $29.6 million after commissions to the selling agents on shares sold and

offering costs. As of June 30, 2020, sales transactions representing 15,000 shares had not settled and are not included in shares issued and outstanding on the face of the consolidated balance sheet, but are included in the weighted-average shares outstanding in the consolidated statement of operations and in the shares used to calculate net asset value per share. As of June 30, 2020, 7,451,635 shares remained available for sale under the ATM Program.

        During the year ended December 31, 2019, Main Street sold 2,247,187 shares of its common stock at a weighted-average price of $40.05 per share and raised $90.0 million of gross proceeds under the ATM Program. Net proceeds were $88.8 million after commissions to the selling agents on shares sold and offering costs.

NOTE I—DIVIDEND REINVESTMENT PLAN ("DRIP")

        Main Street's DRIP provides for the reinvestment of dividends on behalf of its stockholders, unless a stockholder has elected to receive dividends in cash. As a result, if Main Street declares a cash dividend, its stockholders who have not "opted out" of the DRIP by the dividend record date will have their cash dividend automatically reinvested into additional shares of MSCC common stock. The share requirements of the DRIP may be satisfied through the issuance of shares of common stock or through open market purchases of common stock by the DRIP plan administrator. Newly issued shares will be valued based upon the final closing price of MSCC's common stock on the valuation date determined for each dividend by Main Street's Board of Directors. Shares purchased in the open market to satisfy the DRIP requirements will be valued based upon the average price of the applicable shares purchased, before any associated brokerage or other costs. Main Street's DRIP is administered by its transfer agent on behalf of Main Street's record holders and participating brokerage firms. Brokerage firms and other financial intermediaries may decide not to participate in Main Street's DRIP but may provide a similar dividend reinvestment plan for their clients.

        For the six months ended June 30, 2020, $8.1 million of the total $79.6 million in dividends paid to stockholders represented DRIP participation. During this period, the DRIP participation requirements were satisfied with the issuance of 254,951 newly issued shares. For the six months ended June 30, 2019, $9.0 million of the total $89.4 million in dividends paid to stockholders represented DRIP participation. During this period, the DRIP participation requirements were satisfied with the issuance of 229,317 newly issued shares. The shares disclosed above relate only to Main Street's DRIP and exclude any activity related to broker-managed dividend reinvestment plans.

NOTE J—SHARE-BASED COMPENSATION

        Main Street accounts for its share-based compensation plans using the fair value method, as prescribed by ASC 718, Compensation—Stock Compensation. Accordingly, for restricted stock awards, Main Street measured the grant date fair value based upon the market price of its common stock on the date of the grant and amortizes the fair value of the awards as share-based compensation expense over the requisite service period, which is generally the vesting term.

        Main Street's Board of Directors approves the issuance of shares of restricted stock to Main Street employees pursuant to the Main Street Capital Corporation 2015 Equity and Incentive Plan (the "Equity and Incentive Plan"). These shares generally vest over a three-year period from the grant date. The fair value is expensed over the service period, starting on the grant date. The following table summarizes the restricted stock issuances approved by Main Street's Board of Directors under the Equity and Incentive Plan, net of shares forfeited, if any, and the remaining shares of restricted stock available for issuance as of June 30, 2020.

        As of June 30, 2020, there was $17.2 million of total unrecognized compensation expense related to Main Street's non-vested restricted shares. This compensation expense is expected to be recognized over a remaining weighted-average period of approximately 2.2 years as of June 30, 2020.

process to manage its liquidity and ensure that it has available capital to fund its unfunded commitments as necessary. The Company had total unrealized depreciation of $0.8 million on the outstanding unfunded commitments as of June 30, 2020.

        Effective January 1, 2019, ASC 842 required that a lessee evaluate its leases to determine whether they should be classified as operating or financing leases. Main Street identified one operating lease for its office space. The lease commenced May 15, 2017 and expires January 31, 2028. It contains two five-year extension options for a final expiration date of January 31, 2038.

        As Main Street classified this lease as an operating lease prior to implementation, ASC 842-10-65-1 indicates that a right-of-use asset and lease liability should be recorded based on the effective date. Main Street adopted ASC 842 effective January 1, 2019 and recorded a right-of-use asset and a lease liability as of that date. After this date, Main Street has recorded lease expense on a straight-line basis, consistent with the accounting treatment for lease expense prior to the adoption of ASC 842.

        Total operating lease cost incurred by Main Street for each of the three months ended June 30, 2020 and 2019 was $0.2 million. Total operating lease cost incurred by Main Street for each of the six months ended June 30, 2020 and 2019 was $0.4 million. As of June 30, 2020, the asset related to the operating lease was $4.5 million and is included in the interest receivable and other assets balance on the consolidated balance sheet. The lease liability was $5.3 million and is included in the accounts payable and other liabilities balance on the consolidated balance sheet. As of June 30, 2020, the remaining lease term was 7.6 years and the discount rate was 4.2%.

        Main Street may, from time to time, be involved in litigation arising out of its operations in the normal course of business or otherwise. Furthermore, third parties may try to impose liability on Main Street in connection with the activities of its portfolio companies. While the outcome of any current legal proceedings cannot at this time be predicted with certainty, Main Street does not expect any current matters will materially affect its financial condition or results of operations; however, there can be no assurance whether any pending legal proceedings will have a material adverse effect on Main Street's financial condition or results of operations in any future reporting period.

NOTE L—RELATED PARTY TRANSACTIONS

        As discussed further in Note D, the External Investment Manager is treated as a wholly owned portfolio company of MSCC and is included as part of Main Street's Investment Portfolio. At June 30,

Notes to Consolidated Financial Statements (Continued)

(Unaudited)

2020, Main Street had a receivable of approximately $4.8 million due from the External Investment Manager, which included (i) approximately $3.8 million related primarily to operating expenses incurred by MSCC or its subsidiaries as required to support the External Investment Manager's business and amounts due from the External Investment Manager to Main Street under a tax sharing agreement (see further discussion in Note D) and (ii) approximately $1.1 million of dividends declared but not paid by the External Investment Manager.

        In November 2015, Main Street's Board of Directors approved and adopted the Main Street Capital Corporation Deferred Compensation Plan (the "2015 Deferred Compensation Plan"). The 2015 Deferred Compensation Plan became effective on January 1, 2016 and replaced the Deferred Compensation Plan for Non-Employee Directors previously adopted by the Board of Directors in June 2013 (the "2013 Deferred Compensation Plan"). Under the 2015 Deferred Compensation Plan, non-employee directors and certain key employees may defer receipt of some or all of their cash compensation and directors' fees, subject to certain limitations. Individuals participating in the 2015 Deferred Compensation Plan receive distributions of their respective balances based on predetermined payout schedules or other events as defined by the plan and are also able to direct investments made on their behalf among investment alternatives permitted from time to time under the plan, including phantom Main Street stock units. As of June 30, 2020, $9.9 million of compensation and directors' fees had been deferred under the 2015 Deferred Compensation Plan (including amounts previously deferred under the 2013 Deferred Compensation Plan). Of this amount, $5.0 million was deferred into phantom Main Street stock units, representing 152,633 shares of Main Street's common stock. Including phantom stock units issued through dividend reinvestment and net of any shares distributed, the phantom stock units outstanding as of June 30, 2020 represented 154,179 shares of Main Street's common stock. Any amounts deferred under the plan represented by phantom Main Street stock units will not be issued or included as outstanding on the consolidated statements of changes in net assets until such shares are actually distributed to the participant in accordance with the plan, but the related phantom stock units are included in weighted-average shares outstanding with the related dollar amount of the deferral included in total expenses in Main Street's consolidated statements of operations as earned. The dividend amounts related to additional phantom stock units are included in the statements of changes in net assets as an increase to dividends to stockholders offset by a corresponding increase to additional paid-in capital.

NOTE M—SUBSEQUENT EVENTS

        During August 2020, Main Street declared regular monthly dividends of $0.205 per share for each month of October, November and December of 2020. These regular monthly dividends equal a total of $0.615 per share for the fourth quarter of 2020, unchanged from the regular monthly dividends paid in the fourth quarter of 2019. Including the regular monthly dividends declared for the third and fourth quarters of 2020, Main Street will have paid $29.60 per share in cumulative dividends since its October 2007 initial public offering.

        In July 2020, Main Street announced that its External Investment Manager had entered into a definitive asset purchase agreement under which it will become the sole investment adviser and administrator to HMS Income, subject to certain closing conditions. The parties expect the transaction to be completed in the fourth quarter of 2020. Following the closing of the transaction, the External Investment Manager will replace HMS Adviser as the investment adviser and administrator to HMS Income. The base management fee rate under the External Investment Manager's proposed new investment advisory agreement with HMS Income, which has been unanimously approved by the board

of directors of HMS Income, will be reduced from 2.00% to 1.75%, with no changes to the incentive fee calculations. The consummation of the transactions contemplated by the asset purchase agreement is subject to approval of the new investment advisory agreement by stockholders of HMS Income and other customary closing conditions. Post-closing, HMS Income is expected to change its name to MSC Income Fund, Inc.

        In July 2020, Main Street issued an additional $125.0 million aggregate principal amount of the 5.20% Notes at an issue price of 102.674%, for total net proceeds to Main Street, resulting from the issue price and after underwriting discounts and estimated offering expenses payable by Main Street, of approximately $127.3 million. Following the issuance of the additional $125.0 million aggregate principal amount of the 5.20% Notes in July 2020, the outstanding principal balance of the 5.20% Notes was $450.0 million. The 5.20% Notes issued in July 2020 have identical terms as, and are a part of a single series with, the 5.20% Notes issued in April 2019 and in December 2019. The aggregate net proceeds from the 5.20% Notes issuances were used to repay a portion of the borrowings outstanding under the Credit Facility.

ORGANIZATION

        Main Street Capital Corporation ("MSCC") is a principal investment firm primarily focused on providing customized debt and equity financing to lower middle market ("LMM") companies and debt capital to middle market ("Middle Market") companies. The portfolio investments of MSCC and its consolidated subsidiaries are typically made to support management buyouts, recapitalizations, growth financings, refinancings and acquisitions of companies that operate in a variety of industry sectors. MSCC seeks to partner with entrepreneurs, business owners and management teams and generally provides "one stop" financing alternatives within its LMM portfolio. MSCC and its consolidated subsidiaries invest primarily in secured debt investments, equity investments, warrants and other securities of LMM companies based in the United States and in secured debt investments of Middle Market companies generally headquartered in the United States.

        MSCC was formed in March 2007 to operate as an internally managed business development company ("BDC") under the Investment Company Act of 1940, as amended (the "1940 Act"). MSCC wholly owns several investment funds, including Main Street Mezzanine Fund, LP ("MSMF"), Main Street Capital II, LP ("MSC II") and Main Street Capital III, LP ("MSC III" and, collectively with MSMF and MSC II, the "Funds"), and each of their general partners. The Funds are each licensed as a Small Business Investment Company ("SBIC") by the United States Small Business Administration ("SBA"). Because MSCC is internally managed, all of the executive officers and other employees are employed by MSCC. Therefore, MSCC does not pay any external investment advisory fees, but instead

108


Table of Contents

directly incurs the operating costs associated with employing investment and portfolio management professionals.

        MSC Adviser I, LLC (the "External Investment Manager") was formed in November 2013 as a wholly owned subsidiary of MSCC to provide investment management and other services to parties other than MSCC and its subsidiaries or their portfolio companies ("External Parties") and receives fee income for such services. MSCC has been granted no-action relief by the SEC to allow the External Investment Manager to register as a registered investment adviser under the Investment Advisers Act of 1940, as amended. Since the External Investment Manager conducts all of its investment management activities for External Parties, it is accounted for as a portfolio investment of MSCC and is not included as a consolidated subsidiary of MSCC in MSCC's consolidated financial statements.

        MSCC has elected to be treated for U.S. federal income tax purposes as a regulated investment company ("RIC") under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). As a result, MSCC generally will not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that it distributes to its stockholders.

        MSCC has certain direct and indirect wholly owned subsidiaries that have elected to be taxable entities (the "Taxable Subsidiaries"). The primary purpose of the Taxable Subsidiaries is to permit MSCC to hold equity investments in portfolio companies which are "pass-through" entities for tax purposes.

        Unless otherwise noted or the context otherwise indicates, the terms "we," "us," "our," the "Company" and "Main Street" refer to MSCC and its consolidated subsidiaries, which include the Funds and the Taxable Subsidiaries.

COVID-19 UPDATE

        The COVID-19 pandemic, and the related effect on the U.S. and global economies, has had, and threatens to continue to have, adverse consequences for our business and operating results, and the businesses and operating results of our portfolio companies. During the quarter ended June 30, 2020, we continued to work collectively with our employees and portfolio companies to navigate the significant challenges created by the COVID-19 pandemic. We remain focused on ensuring the safety of our employees and the employees of our portfolio companies, while also managing our ongoing business activities. In this regard, we remain heavily engaged with our portfolio companies. As discussed below under "Discussion and Analysis of Results of Operations," our investment income, principally our interest and dividend income, has been negatively impacted by the economic effects of COVID-19 through the first six months of 2020. In addition, our net asset value as of June 30, 2020 decreased as compared to our net asset value as of December 31, 2019, primarily due to the unrealized depreciation of our Investment Portfolio caused by the immediate adverse economic effects of the COVID-19 pandemic and uncertainty regarding the extent and duration of its impact, as well as the negative impact of the pandemic on our investment income. We continue to maintain access to multiple sources of liquidity, including cash, unused capacity under our Credit Facility and remaining SBIC debenture capacity, and from December 31, 2019 to June 30, 2020, our total liquidity improved from $495.5 million to $528.7 million. As of June 30, 2020, we were in compliance with all debt covenants and do not anticipate any issues with our ability to comply with all covenants in the future. Refer to "—Liquidity and Capital Resources" below for further discussion as of June 30, 2020.

        Neither our management nor our Board of Directors is able to predict the full impact of the COVID-19 pandemic, including its duration and the magnitude of its economic and societal impact. As such, while we will continue to monitor the rapidly evolving situation and guidance from U.S. and international authorities, including federal, state and local public health authorities, we are unable to predict with any certainty the extent to which the outbreak will negatively affect our portfolio

companies' operating results and financial condition or the impact that such disruptions may have on our results of operations and financial condition in the future.

OVERVIEW

        Our principal investment objective is to maximize our portfolio's total return by generating current income from our debt investments and capital appreciation from our equity and equity-related investments, including warrants, convertible securities and other rights to acquire equity securities in a portfolio company. Our LMM companies generally have annual revenues between $10 million and $150 million, and our LMM portfolio investments generally range in size from $5 million to $50 million. Our Middle Market investments are made in businesses that are generally larger in size than our LMM portfolio companies, with annual revenues typically between $150 million and $1.5 billion, and our Middle Market investments generally range in size from $3 million to $20 million. Our private loan ("Private Loan") portfolio investments are primarily debt securities in privately held companies which have been originated through strategic relationships with other investment funds on a collaborative basis. Private Loan investments are typically similar in size, structure, terms and conditions to investments we hold in our LMM portfolio and Middle Market portfolio.

        We seek to fill the financing gap for LMM businesses, which, historically, have had limited access to financing from commercial banks and other traditional sources. The underserved nature of the LMM creates the opportunity for us to meet the financing needs of LMM companies while also negotiating favorable transaction terms and equity participations. Our ability to invest across a company's capital structure, from secured loans to equity securities, allows us to offer portfolio companies a comprehensive suite of financing options, or a "one stop" financing solution. Providing customized, "one stop" financing solutions is important to LMM portfolio companies. We generally seek to partner directly with entrepreneurs, management teams and business owners in making our investments. Our LMM portfolio debt investments are generally secured by a first lien on the assets of the portfolio company and typically have a term of between five and seven years from the original investment date.

        Our Middle Market portfolio investments primarily consist of direct investments in or secondary purchases of interest-bearing debt securities in privately held companies that are generally larger in size than the companies included in our LMM portfolio. Our Middle Market portfolio debt investments are generally secured by either a first or second priority lien on the assets of the portfolio company and typically have an expected duration of between three and seven years from the original investment date.

        Our Private Loan portfolio investments are primarily debt securities in privately held companies that have been originated through strategic relationships with other investment funds on a collaborative basis and are often referred to in the debt markets as "club deals." Private Loan investments are typically similar in size, structure, terms and conditions to investments we hold in our LMM portfolio and Middle Market portfolio. Our Private Loan portfolio debt investments are generally secured by either a first or second priority lien on the assets of the portfolio company and typically have a term of between three and seven years from the original investment date.

        Our other portfolio ("Other Portfolio") investments primarily consist of investments that are not consistent with the typical profiles for our LMM, Middle Market or Private Loan portfolio investments, including investments which may be managed by third parties. In our Other Portfolio, we may incur indirect fees and expenses in connection with investments managed by third parties, such as investments in other investment companies or private funds.

        Our external asset management business is conducted through the External Investment Manager. The External Investment Manager earns management fees based on the assets of the funds under management and may earn incentive fees, or a carried interest, based on the performance of the funds managed. We have entered into an agreement with the External Investment Manager to share employees in connection with its asset management business generally, and specifically for its

110


Table of Contents

relationship with HMS Income Fund, Inc. ("HMS Income"). Through this agreement, we share employees with the External Investment Manager, including their related infrastructure, business relationships, management expertise and capital raising capabilities.

        The following tables provide a summary of our investments in the LMM, Middle Market and Private Loan portfolios as of June 30, 2020 and December 31, 2019 (this information excludes the Other Portfolio investments and the External Investment Manager which are discussed further below):

At June 30, 2020, we had equity ownership in approximately 99% of our LMM portfolio companies, and the average fully diluted equity ownership in those portfolio companies was approximately 41%.

(b)
The weighted-average annual effective yields were computed using the effective interest rates for all debt investments at cost as of June 30, 2020, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt instruments and any debt investments on non-accrual status. Weighted-average annual effective yield is higher than what an investor in shares of our common stock will realize on its investment because it does not reflect our expenses or any sales load paid by an investor.

(c)
The average EBITDA is calculated using a simple average for the LMM portfolio and a weighted-average for the Middle Market and Private Loan portfolios. These calculations exclude certain portfolio companies, including two LMM portfolio companies, two Middle Market portfolio companies and four Private Loan portfolio companies, as EBITDA is

(b)
The weighted-average annual effective yields were computed using the effective interest rates for all debt investments at cost as of December 31, 2019, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt instruments and any debt investments on non-accrual status. Weighted-average annual effective yield is higher than what an investor in shares of our common stock will realize on its investment because it does not reflect our expenses or any sales load paid by an investor.

(c)
The average EBITDA is calculated using a simple average for the LMM portfolio and a weighted-average for the Middle Market and Private Loan portfolios. These calculations exclude certain portfolio companies, including three LMM portfolio companies, two Middle Market portfolio companies and three Private Loan portfolio companies, as EBITDA is not a meaningful valuation metric for our investments in these portfolio companies, and those portfolio companies whose primary purpose is to own real estate.

        As of June 30, 2020, we had Other Portfolio investments in twelve companies, collectively totaling approximately $98.1 million in fair value and approximately $126.4 million in cost basis and which comprised approximately 4.1% of our Investment Portfolio (as defined in "Critical Accounting Policies—Basis of Presentation" below) at fair value. As of December 31, 2019, we had Other Portfolio investments in eleven companies, collectively totaling approximately $106.7 million in fair value and approximately $118.4 million in cost basis and which comprised approximately 4.1% of our Investment Portfolio at fair value.

        As previously discussed, the External Investment Manager is a wholly owned subsidiary that is treated as a portfolio investment. As of June 30, 2020, there was no cost basis in this investment and the investment had a fair value of approximately $69.1 million, which comprised approximately 2.9% of our Investment Portfolio at fair value. As of December 31, 2019, there was no cost basis in this investment and the investment had a fair value of approximately $74.5 million, which comprised approximately 2.9% of our Investment Portfolio at fair value.

        Our portfolio investments are generally made through MSCC and the Funds. MSCC and the Funds share the same investment strategies and criteria, although they are subject to different

112


Table of Contents

regulatory regimes. An investor's return in MSCC will depend, in part, on the Funds' investment returns as they are wholly owned subsidiaries of MSCC.

        The level of new portfolio investment activity will fluctuate from period to period based upon our view of the current economic fundamentals, our ability to identify new investment opportunities that meet our investment criteria, and our ability to consummate the identified opportunities. The level of new investment activity, and associated interest and fee income, will directly impact future investment income. In addition, the level of dividends paid by portfolio companies and the portion of our portfolio debt investments on non-accrual status will directly impact future investment income. While we intend to grow our portfolio and our investment income over the long term, our growth and our operating results may be more limited during depressed economic periods. However, we intend to appropriately manage our cost structure and liquidity position based on applicable economic conditions and our investment outlook. The level of realized gains or losses and unrealized appreciation or depreciation on our investments will also fluctuate depending upon portfolio activity, economic conditions and the performance of our individual portfolio companies. The changes in realized gains and losses and unrealized appreciation or depreciation could have a material impact on our operating results.

        Because we are internally managed, we do not pay any external investment advisory fees, but instead directly incur the operating costs associated with employing investment and portfolio management professionals. We believe that our internally managed structure provides us with a beneficial operating expense structure when compared to other publicly traded and privately held investment firms which are externally managed, and our internally managed structure allows us the opportunity to leverage our non-interest operating expenses as we grow our Investment Portfolio. For the trailing twelve months ended June 30, 2020 and 2019, the ratio of our total operating expenses, excluding interest expense, as a percentage of our quarterly average total assets was 1.2% and 1.3%, respectively, and 1.4% for the year ended December 31, 2019.

        During May 2012, we entered into an investment sub-advisory agreement with HMS Adviser, LP ("HMS Adviser"), which is the investment advisor to HMS Income, a non-listed BDC, to provide certain investment advisory services to HMS Adviser. In December 2013, after obtaining required no-action relief from the SEC to allow us to own a registered investment adviser, we assigned the sub-advisory agreement to the External Investment Manager since the fees received from such arrangement could otherwise have negative consequences on our ability to meet the source-of-income requirement necessary for us to maintain our RIC tax treatment. Under the investment sub-advisory agreement, the External Investment Manager is entitled to 50% of the base management fee and the incentive fees earned by HMS Adviser under its advisory agreement with HMS Income. During the three months ended June 30, 2020 and 2019, the External Investment Manager earned $2.3 million and $4.1 million, respectively, in base management fee income. No incentive fee income was earned in the three months ended June 30, 2020 compared to $1.3 million earned in the three months ended June 30, 2019. During the six months ended June 30, 2020, the External Investment Manager earned $4.8 million in base management fee income and no incentive fees compared to $5.7 million of base management fees and $1.4 million in incentive fees for the comparable period in 2019 under the sub-advisory agreement with HMS Adviser.

        During April 2014, we received an exemptive order from the SEC permitting co-investments by us and HMS Income in certain negotiated transactions where co-investing would otherwise be prohibited under the 1940 Act. We have made, and in the future intend to continue to make, such co-investments with HMS Income in accordance with the conditions of the order. The order requires, among other things, that we and the External Investment Manager consider whether each such investment opportunity is appropriate for HMS Income and, if it is appropriate, to propose an allocation of the investment opportunity between us and HMS Income. Because the External Investment Manager may receive performance-based fee compensation from HMS Income, this may provide it an incentive to allocate opportunities to HMS Income instead of us. However, both we and the External Investment

Manager have policies and procedures in place to manage this conflict. We have filed a new application for co-investment exemptive relief with the SEC that would provide greater flexibility in structuring and effectuating co-investment transactions between us, HMS Income and certain other funds managed by us as described in the application. Our new application for co-investment exemptive relief has not yet been granted, and there is no assurance that such relief will be granted on the terms and conditions in the application or at all. Pending the receipt of such new co-investment relief, we intend to continue to rely on our current co-investment relief.

CRITICAL ACCOUNTING POLICIES

    Basis of Presentation

        Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"). For each of the periods presented herein, our consolidated financial statements include the accounts of MSCC and its consolidated subsidiaries. The Investment Portfolio, as used herein, refers to all of our investments in LMM portfolio companies, investments in Middle Market portfolio companies, Private Loan portfolio investments, Other Portfolio investments, and the investment in the External Investment Manager. Our results of operations for the three and six months ended June 30, 2020 and 2019, cash flows for the six months ended June 30, 2020 and 2019, and financial position as of June 30, 2020 and December 31, 2019, are presented On a consolidated basis. The effects of all intercompany transactions between us and our consolidated subsidiaries have been eliminated in consolidation.

        Our accompanying unaudited consolidated financial statements are presented in conformity with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Articles 6, 10 and 12 of Regulation S-X. Accordingly, certain disclosures accompanying annual financial statements prepared in accordance with U.S. GAAP are omitted. In the opinion of management, the unaudited consolidated financial results included herein contain all adjustments, consisting solely of normal recurring accruals, considered necessary for the fair presentation of financial statements for the interim periods included herein. The results of operations for the three and six months ended June 30, 2020 and 2019 are not necessarily indicative of the operating results to be expected for the full year. Also, the unaudited financial statements and notes should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2019. Financial statements prepared on a U.S. GAAP basis require management to make estimates and assumptions that affect the amounts and disclosures reported in the financial statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein.

        We are an investment company following the accounting and reporting guidance in Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 946, Financial Services—Investment Companies ("ASC 946"). Under ASC 946, we are precluded from consolidating other entities in which we have equity investments, including those in which we have a controlling interest, unless the other entity is another investment company. An exception to this general principle in ASC 946 occurs if we hold a controlling interest in an operating company that provides all or substantially all of its services directly to us or to any of our portfolio companies. Accordingly, as noted above, our consolidated financial statements include the financial position and operating results for the Funds and the Taxable Subsidiaries. We have determined that none of our portfolio investments qualify for this exception, including the investment in the External Investment Manager. Therefore, our Investment Portfolio is carried on the consolidated balance sheet at fair value with any adjustments to fair value recognized as "Net Unrealized Appreciation (Depreciation)" on the consolidated statements of operations until the investment is realized, usually upon exit, resulting in any gain or loss being recognized as a "Net Realized Gain (Loss)."

    Investment Portfolio Valuation

        The most significant determination inherent in the preparation of our consolidated financial statements is the valuation of our Investment Portfolio and the related amounts of unrealized appreciation and depreciation. As of June 30, 2020 and December 31, 2019, our Investment Portfolio valued at fair value represented approximately 95% and 96% of our total assets, respectively. We are required to report our investments at fair value. We follow the provisions of FASB ASC 820, Fair Value Measurements and Disclosures ("ASC 820"). ASC 820 defines fair value, establishes a framework for measuring fair value, establishes a fair value hierarchy based on the quality of inputs used to measure fair value and enhances disclosure requirements for fair value measurements. ASC 820 requires us to assume that the portfolio investment is to be sold in the principal market to independent market participants, which may be a hypothetical market. Market participants are defined as buyers and sellers in the principal market that are independent, knowledgeable and willing and able to transact. See "Note B.1.—Valuation of the Investment Portfolio" in the notes to consolidated financial statements for a detailed discussion of our investment portfolio valuation process and procedures.

        Due to the inherent uncertainty in the valuation process, our determination of fair value for our Investment Portfolio may differ materially from the values that would have been determined had a ready market for the securities existed. In addition, changes in the market environment, portfolio company performance and other events that may occur over the lives of the investments may cause the gains or losses ultimately realized on these investments to be materially different than the valuations currently assigned. We determine the fair value of each individual investment and record changes in fair value as unrealized appreciation or depreciation.

        Our Board of Directors has the final responsibility for overseeing, reviewing and approving, in good faith, our determination of the fair value for our Investment Portfolio and our valuation procedures, consistent with 1940 Act requirements. We believe our Investment Portfolio as of June 30, 2020 and December 31, 2019 approximates fair value as of those dates based on the markets in which we operate and other conditions in existence on those reporting dates.

    Revenue Recognition

    Interest and Dividend Income

        We record interest and dividend income on the accrual basis to the extent amounts are expected to be collected. Dividend income is recorded as dividends are declared by the portfolio company or at the point an obligation exists for the portfolio company to make a distribution. In accordance with our valuation policies, we evaluate accrued interest and dividend income periodically for collectability. When a loan or debt security becomes 90 days or more past due, and if we otherwise do not expect the debtor to be able to service all of its debt or other obligations, we will generally place the loan or debt security on non-accrual status and cease recognizing interest income on that loan or debt security until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a loan or debt security's status significantly improves regarding the debtor's ability to service the debt or other obligations, or if a loan or debt security is sold or written off, we remove it from non-accrual status.

    Fee Income

        We may periodically provide services, including structuring and advisory services, to our portfolio companies or other third parties. For services that are separately identifiable and evidence exists to substantiate fair value, fee income is recognized as earned, which is generally when the investment or other applicable transaction closes. Fees received in connection with debt financing transactions for services that do not meet these criteria are treated as debt origination fees and are deferred and accreted into income over the life of the financing.

115


Table of Contents

    Payment-in-Kind ("PIK") Interest and Cumulative Dividends

        We hold certain debt and preferred equity instruments in our Investment Portfolio that contain PIK interest and cumulative dividend provisions. The PIK interest, computed at the contractual rate specified in each debt agreement, is periodically added to the principal balance of the debt and is recorded as interest income. Thus, the actual collection of this interest may be deferred until the time of debt principal repayment. Cumulative dividends are recorded as dividend income, and any dividends in arrears are added to the balance of the preferred equity investment. The actual collection of these dividends in arrears may be deferred until such time as the preferred equity is redeemed or sold. To maintain RIC tax treatment (as discussed below), these non-cash sources of income may need to be paid out to stockholders in the form of distributions, even though we may not have collected the PIK interest and cumulative dividends in cash. We stop accruing PIK interest and cumulative dividends and write off any accrued and uncollected interest and dividends in arrears when we determine that such PIK interest and dividends in arrears are no longer collectible. For the three months ended June 30, 2020 and 2019, (i) approximately 2.5% and 2.2%, respectively, of our total investment income was attributable to PIK interest income not paid currently in cash and (ii) approximately 0.9% and 1.1%, respectively, of our total investment income was attributable to cumulative dividend income not paid currently in cash. For the six months ended June 30, 2020 and 2019, (i) approximately 1.7% and 2.0%, respectively, of our total investment income was attributable to PIK interest income not paid currently in cash and (ii) approximately 0.9% and 1.1%, respectively, of our total investment income was attributable to cumulative dividend income not paid currently in cash.

    Share-Based Compensation

        We account for our share-based compensation plans using the fair value method, as prescribed by ASC 718, Compensation—Stock Compensation. Accordingly, for restricted stock awards, we measure the grant date fair value based upon the market price of our common stock on the date of the grant and amortize the fair value of the awards as share-based compensation expense over the requisite service period, which is generally the vesting term.

        We have also adopted Accounting Standards Update ("ASU") 2016-09, Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which requires that all excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) be recognized as income tax expense or benefit in the income statement and not delay recognition of a tax benefit until the tax benefit is realized through a reduction to taxes payable. Accordingly, the tax effects of exercised or vested awards are treated as discrete items in the reporting period in which they occur. Additionally, we have elected to account for forfeitures as they occur.

    Income Taxes

        MSCC has elected to be treated for U.S. federal income tax purposes as a RIC. MSCC's taxable income includes the taxable income generated by MSCC and certain of its subsidiaries, including the Funds, which are treated as disregarded entities for tax purposes. As a RIC, MSCC generally will not pay corporate-level U.S. federal income taxes on any net ordinary taxable income or capital gains that MSCC distributes to its stockholders. MSCC must generally distribute at least 90% of its "investment company taxable income" (which is generally its net ordinary taxable income and realized net short-term capital gains in excess of realized net long-term capital losses) and 90% of its tax-exempt income to maintain its RIC status (pass-through tax treatment for amounts distributed). As part of maintaining RIC status, undistributed taxable income (subject to a 4% non-deductible U.S. federal excise tax) pertaining to a given fiscal year may be distributed up to 12 months subsequent to the end of that fiscal year, provided such dividends are declared on or prior to the later of (i) filing of the U.S. federal income tax return for the applicable fiscal year or (ii) the fifteenth day of the ninth month following the close of the year in which such taxable income was generated.

Table of Contents

        The Taxable Subsidiaries primarily hold certain portfolio investments for us. The Taxable Subsidiaries permit us to hold equity investments in portfolio companies which are "pass-through" entities for tax purposes and to continue to comply with the "source-of-income" requirements contained in the RIC tax provisions of the Code. The Taxable Subsidiaries are consolidated with us for U.S. GAAP financial reporting purposes, and the portfolio investments held by the Taxable Subsidiaries are included in our consolidated financial statements as portfolio investments and recorded at fair value. The Taxable Subsidiaries are not consolidated with MSCC for income tax purposes and may generate income tax expense, or benefit, and tax assets and liabilities, as a result of their ownership of certain portfolio investments. The taxable income, or loss, of the Taxable Subsidiaries may differ from their book income, or loss, due to temporary book and tax timing differences and permanent differences. The Taxable Subsidiaries are each taxed at their normal corporate tax rates based on their taxable income. The income tax expense, or benefit, if any, and the related tax assets and liabilities, of the Taxable Subsidiaries are reflected in our consolidated financial statements.

        The External Investment Manager is an indirect wholly owned subsidiary of MSCC owned through a Taxable Subsidiary and is a disregarded entity for tax purposes. The External Investment Manager has entered into a tax sharing agreement with its Taxable Subsidiary owner. Since the External Investment Manager is accounted for as a portfolio investment of MSCC and is not included as a consolidated subsidiary of MSCC in MSCC's consolidated financial statements, and as a result of the tax sharing agreement with its Taxable Subsidiary owner, for its stand-alone financial reporting purposes the External Investment Manager is treated as if it is taxed at normal corporate tax rates based on its taxable income and, as a result of its activities, may generate income tax expense or benefit. The income tax expense, or benefit, if any, and the related tax assets and liabilities, of the External Investment Manager are reflected in the External Investment Manager's separate financial statements.

        The Taxable Subsidiaries and the External Investment Manager use the liability method in accounting for income taxes. Deferred tax assets and liabilities are recorded for temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements, using statutory tax rates in effect for the year in which the temporary differences are expected to reverse. A valuation allowance is provided, if necessary, against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized.

        Taxable income generally differs from net income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses. Taxable income generally excludes net unrealized appreciation or depreciation, as investment gains or losses are not included in taxable income until they are realized.

INVESTMENT PORTFOLIO COMPOSITION

        Our LMM portfolio investments primarily consist of secured debt, equity warrants and direct equity investments in privately held, LMM companies based in the United States. Our LMM portfolio companies generally have annual revenues between $10 million and $150 million, and our LMM investments generally range in size from $5 million to $50 million. The LMM debt investments are typically secured by either a first or second priority lien on the assets of the portfolio company, can include either fixed or floating rate terms and generally have a term of between five and seven years from the original investment date. In most LMM portfolio investments, we receive nominally priced equity warrants and/or make direct equity investments in connection with a debt investment.

        Our Middle Market portfolio investments primarily consist of direct investments in or secondary purchases of interest-bearing debt securities in privately held companies based in the United States that are generally larger in size than the companies included in our LMM portfolio. Our Middle Market portfolio companies generally have annual revenues between $150 million and $1.5 billion, and our Middle Market investments generally range in size from $3 million to $20 million. Our Middle Market

117


Table of Contents

portfolio debt investments are generally secured by either a first or second priority lien on the assets of the portfolio company and typically have a term of between three and seven years from the original investment date.

        Our Private Loan portfolio investments are primarily debt securities in privately held companies which have been originated through strategic relationships with other investment funds on a collaborative basis and are often referred to in the debt markets as "club deals." Private Loan investments are typically similar in size, structure, terms and conditions to investments we hold in our LMM portfolio and Middle Market portfolio. Our Private Loan portfolio debt investments are generally secured by either a first or second priority lien on the assets of the portfolio company and typically have a term of between three and seven years from the original investment date.

        Our Other Portfolio investments primarily consist of investments which are not consistent with the typical profiles for LMM, Middle Market and Private Loan portfolio investments, including investments which may be managed by third parties. In the Other Portfolio, we may incur indirect fees and expenses in connection with investments managed by third parties, such as investments in other investment companies or private funds.

        Our external asset management business is conducted through the External Investment Manager. The External Investment Manager earns management fees based on the assets of the funds under management and may earn incentive fees, or a carried interest, based on the performance of the funds managed. We have entered into an agreement with the External Investment Manager to share employees in connection with its asset management business generally, and specifically for its relationship with HMS Income. Through this agreement, we share employees with the External Investment Manager, including their related infrastructure, business relationships, management expertise and capital raising capabilities, and we allocate the related expenses to the External Investment Manager pursuant to the sharing agreement. Our total expenses for the three months ended June 30, 2020 and 2019 are net of expenses allocated to the External Investment Manager of $1.8 million and $1.7 million, respectively. Our total expenses for each of the six months ended June 30, 2020 and 2019 are net of expenses allocated to the External Investment Manager of $3.4 million . The External Investment Manager earns management fees based on the assets of the funds under management and may earn incentive fees, or a carried interest, based on the performance of the funds managed. The total contribution of the External Investment Manager to our net investment income consists of the combination of the expenses allocated to the External Investment Manager and the dividend income earned from the External Investment Manager. For the three months ended June 30, 2020 and 2019, the total contribution to our net investment income was $2.2 million and $3.6 million, respectively. For the six months ended June 30, 2020 and 2019, the total contribution to our net investment income was $4.5 million and $6.2 million, respectively.

        The following tables summarize the composition of our total combined LMM portfolio investments, Middle Market portfolio investments and Private Loan portfolio investments at cost and fair value by type of investment as a percentage of the total combined LMM portfolio investments, Middle Market portfolio investments and Private Loan portfolio investments as of June 30, 2020 and

        Our LMM portfolio investments, Middle Market portfolio investments and Private Loan portfolio investments carry a number of risks including: (1) investing in companies which may have limited operating histories and financial resources; (2) holding investments that generally are not publicly traded and which may be subject to legal and other restrictions on resale; and (3) other risks common to investing in below investment grade debt and equity investments in our Investment Portfolio. Please see "Risk Factors—Risks Related to Our Investments" contained in our Form 10-K for the fiscal year ended December 31, 2019 and "Risk Factors" below in this Quarterly Report on Form 10-Q and in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020 for a more complete discussion of the risks involved with investing in our Investment Portfolio.

PORTFOLIO ASSET QUALITY

        We utilize an internally developed investment rating system to rate the performance of each LMM portfolio company and to monitor our expected level of returns on each of our LMM investments in relation to our expectations for the portfolio company. The investment rating system takes into consideration various factors, including each investment's expected level of returns, the collectability of our debt investments and the ability to receive a return of the invested capital in our equity investments, comparisons to competitors and other industry participants, the portfolio company's future outlook and other factors that are deemed to be significant to the portfolio company.

        As of June 30, 2020, our total Investment Portfolio had eleven investments on non-accrual status, which comprised approximately 1.9% of its fair value and 6.3% of its cost. As of December 31, 2019, our total Investment Portfolio had eight investments on non-accrual status, which comprised approximately 1.4% of its fair value and 4.8% of its cost.

        The operating results of our portfolio companies are impacted by changes in the broader fundamentals of the United States economy. In periods during which the United States economy contracts, as it has due to the impact of COVID-19, it is likely that the financial results of small to mid-sized companies, like those in which we invest, could experience deterioration or limited growth from current levels, which could ultimately lead to difficulty in meeting their debt service requirements, to an increase in defaults on our debt investments or in realized losses on our investments and to

difficulty in maintaining historical dividend payment rates and unrealized appreciation on our equity investments. Consequently, we can provide no assurance that the performance of certain portfolio companies will not be negatively impacted by future economic cycles or other conditions, which could also have a negative impact on our future results.

Not Meaningful

(a)
Distributable net investment income is net investment income as determined in accordance with U.S. GAAP, excluding the impact of share-based compensation expense which is non-cash in nature. We believe presenting distributable net investment income and related per share amounts is useful and appropriate supplemental disclosure of information for analyzing our financial performance since share-based compensation does not require settlement in cash. However, distributable net investment income is a non-U.S. GAAP measure and should not be considered as a replacement to net investment income and other earnings measures presented in accordance with U.S. GAAP. Instead, distributable net investment income should be reviewed only in connection with such U.S. GAAP measures in analyzing our financial performance. A reconciliation of net investment income in accordance with U.S. GAAP to distributable net investment income is presented in the table above.

Table of Contents

    Investment Income

        Total investment income for the three months ended June 30, 2020 was $52.0 million, a 15% decrease from the $61.3 million of total investment income for the corresponding period of 2019. This comparable period decrease was principally attributable to (i) a $5.6 million decrease in interest income, which was primarily due to lower floating interest rates on investment portfolio debt investments based upon the decline in the London Interbank Offered Rate ("LIBOR"), and (ii) a $5.0 million decrease in dividend income from Investment Portfolio equity investments, also partially attributable to the current negative impact of the COVID-19 pandemic and, specifically, on certain of our portfolio companies' operating results, financial condition and liquidity, as well as the uncertainty relative to the duration of the pandemic's effects. These decreases were partially offset by a $1.3 million increase in fee income. The $9.3 million decrease in total investment income in the three months ended June 30, 2020 includes the net impact of a $0.3 million increase from accelerated prepayment, repricing and other income activity considered less consistent or non-recurring.

    Expenses

        Total expenses for the three months ended June 30, 2020 decreased to $20.7 million from $21.7 million for the corresponding period of 2019. This decrease in operating expenses was principally attributable to (i) a $0.7 million decrease in compensation expense, (ii) a $0.4 million decrease in interest expense and (iii) a $0.2 million decrease in general and administrative expense, partially offset by a $0.4 million increase in share-based compensation expense. The decrease in compensation expense is primarily related to a $1.7 million decrease in cash incentive compensation accruals, partially offset by a $0.7 million increase in expense as a result of the change in the fair value of our deferred compensation plan assets. The decrease in interest expense is primarily due to a $2.1 million decrease from the repayment of the 4.50% Notes due 2019 (as defined below) effective December 1, 2019, partially offset by a $1.7 million increase as a result of two separate issuances of our 5.20% Notes (as defined below) in April 2019 and December 2019.

    Net Investment Income

        Net investment income for the three months ended June 30, 2020 decreased 21% to $31.3 million, or $0.48 per share, compared to net investment income of $39.6 million, or $0.63 per share, for the corresponding period of 2019. The decrease in net investment income was principally attributable to the decrease in total investment income, partially offset by lower operating expenses, both as discussed above. The decrease in net investment income per share is also attributable to the 4% increase in weighted average shares outstanding to 65.3 million for the three months ended June 30, 2020, primarily due to shares issued through the ATM Program (as defined in "—Liquidity and Capital Resources—Capital Resources" below), shares issued pursuant to our equity incentive plans and shares issued pursuant to our dividend reinvestment plan.

    Distributable Net Investment Income

        Distributable net investment income for the three months ended June 30, 2020 decreased 19% to $34.1 million, or $0.52 per share, compared with $42.0 million, or $0.67 per share, in the corresponding period of 2019. The decline in distributable net investment income was primarily due to the decreased level of total investment income, partially offset by lower operating expenses, both as discussed above. Distributable net investment income on a per share basis for the three months ended June 30, 2020 also reflects a greater number of average shares outstanding compared to the corresponding period in 2019, as described above. The decline in distributable net investment income per share includes a decrease of $0.01 per share due to the increase in compensation expense as a result of the increase in the fair value of the deferred compensation plan assets during the second quarter of 2020.

    Net Increase in Net Assets Resulting from Operations

        The net increase in net assets resulting from operations for the three months ended June 30, 2020 was $43.4 million, or $0.66 per share, compared with $38.3 million, or $0.61 per share, during the three months ended June 30, 2019. This $5.1 million increase from the prior year's comparable period was primarily the result of (i) a $10.9 million benefit from the change in the income tax benefit (provision) and (ii) an $8.3 million increase in net unrealized appreciation from portfolio investments, including the impact of accounting reversals relating to realized gains/income (losses), with these increases partially offset by (i) an $8.3 million decrease in net investment income, as discussed above, and (ii) a $6.0 million increase in the net realized loss from investments. The net realized loss from investments of $8.6 million for the three months ended June 30, 2020 was primarily the result of (i) realized losses of $9.9 million from the exit of three Middle Market investments, partially offset by the net realized gain of $1.6 million resulting from the full exit of two LMM investments and the partial exit of another LMM investment.

        The following table provides a summary of the total net unrealized appreciation of $13.2 million for the three months ended June 30, 2020:

        The income tax benefit for the three months ended June 30, 2020 of $7.5 million principally consisted of a deferred tax benefit of $8.0 million, which is primarily the result of the net activity relating to our portfolio investments held in our Taxable Subsidiaries, including changes in loss carryforwards, changes in net unrealized appreciation/depreciation and other temporary book-tax differences, partially offset by a current tax provision of $0.6 million related to a $0.4 million provision for current U.S. federal and state income taxes, as well as a $0.2 million provision for excise tax on our estimated undistributed taxable income.

(b)
Distributable net investment income is net investment income as determined in accordance with U.S. GAAP, excluding the impact of share-based compensation expense which is non-cash in nature. We believe presenting distributable net investment income and related per share amounts is useful and appropriate supplemental disclosure of information for analyzing our financial performance since share-based compensation does not require settlement in cash. However, distributable net investment income is a non-U.S. GAAP measure and should not be considered as a replacement to net investment income and other earnings measures presented in accordance with U.S. GAAP. Instead, distributable net investment income should be reviewed only in connection with such U.S. GAAP measures in analyzing our financial performance. A reconciliation of net investment income in accordance with U.S. GAAP to distributable net investment income is presented in the table above.

    Investment Income

        Total investment income for the six months ended June 30, 2020 was $108.2 million, a 12% decrease from the $122.7 million of total investment income for the corresponding period of 2019. This comparable period decrease was principally attributable to (i) a $9.4 million decrease in dividend income from Investment Portfolio equity investments, partially attributable to the current negative impact of the COVID-19 pandemic on certain of our portfolio companies' operating results, financial

123


Table of Contents

condition and liquidity, as well as the uncertainty relative to the duration of the pandemic's effects and (ii) a $8.1 million decrease in interest income, primarily due to a decline in floating interest rates on investment portfolio debt investments. These decreases were partially offset by a $3.0 million increase in fee income. The $14.5 million decrease in total investment income in the six months ended June 30, 2020 includes the positive impact of a net increase of $2.7 million from accelerated prepayment, repricing and other income activity considered less consistent or non-recurring.

    Expenses

        Total expenses for the six months ended June 30, 2020 decreased to $40.3 million from $43.6 million in the corresponding period of 2019. This decrease in operating expenses was principally attributable to a $4.3 million decrease in compensation expense, partially offset by a $0.9 million increase in share-based compensation expense. The decrease in compensation expense is primarily related to (i) a $4.2 million decrease in cash incentive compensation accruals and (ii) a $0.8 million decrease as a result of the change in the fair value of our deferred compensation plan assets, partially offset by a $0.6 million increase in base compensation-related expenses.

    Net Investment Income

        Net investment income for the six months ended June 30, 2020 decreased 14% to $67.8 million, or $1.04 per share, compared to net investment income of $79.1 million, or $1.27 per share, for the corresponding period of 2019. The decrease in net investment income was principally attributable to the decrease in total investment income, partially offset by lower operating expenses, both as discussed above, as well as the 4% increase in weighted average shares outstanding to 64.9 million for the six months ended June 30, 2020, primarily due to shares issued through the ATM Program (as defined in "—Liquidity and Capital Resources—Capital Resources" below), shares issued pursuant to our equity incentive plans and shares issued pursuant to our dividend reinvestment plan.

    Distributable Net Investment Income

        Distributable net investment income for the six months ended June 30, 2020 decreased 12% to $73.5 million, or $1.13 per share, compared with $83.8 million, or $1.34 per share, in the corresponding period of 2019. The decline in distributable net investment income was primarily due to the decreased level of total investment income, partially offset by lower operating expenses, both as discussed above. Distributable net investment income on a per share basis for the six months ended June 30, 2020 also reflects a greater number of average shares outstanding compared to the corresponding period in 2019, as described above. The decline in distributable net investment income on a per share basis includes (i) an increase of $0.04 per share due to the increase in interest income from accelerated prepayment, repricing and other income activity considered non-recurring, as discussed above, and (ii) an increase of $0.01 per share due to the decrease in compensation expense as a result of the decrease in the fair value of the deferred compensation plan assets.

    Net Increase (Decrease) in Net Assets Resulting from Operations

        The net increase (decrease) in net assets resulting from operations for the six months ended June 30, 2020 was $(128.1) million, or $(1.97) per share, compared with $79.7 million, or $1.28 per share, during the six months ended June 30, 2019. This $207.7 million decrease from the prior year's comparable period was primarily the result of (i) a $197.2 million decrease in net unrealized appreciation (depreciation) from portfolio investments, primarily caused by the adverse economic effects of the COVID-19 pandemic, and including the impact of accounting reversals relating to realized gains/income (losses), (ii) a $22.2 million increase in the net realized loss from investments, (iii) a $11.3 million decrease in net investment income, as discussed above, and (iv) a $4.5 million decrease in unrealized appreciation on the SBIC debentures accounted for on a fair value basis,

partially offset by (i) a $22.3 million benefit from the change in the income tax benefit (provision) and (ii) a $5.2 million decrease in the net realized loss on extinguishment of debt. The net realized loss from investments of $30.4 million for the six months ended June 30, 2020 was primarily the result of (i) the net realized loss of $12.7 million from the exit of three LMM investments, (ii) the realized loss of $9.9 million from the exit of three Middle Market investments and (iii) the realized loss of $7.1 million resulting from the partial exit of two LMM investments.

        This "Liquidity and Capital Resources" section should be read in conjunction with the "COVID-19 Update" section above.

    Cash Flows

        For the six months ended June 30, 2020, we experienced a net increase in cash and cash equivalents in the amount of $13.3 million, which is the net result of $39.7 million of cash provided by our operating activities and $26.4 million of cash used in our financing activities.

125


Table of Contents

        The $39.7 million of cash provided by our operating activities resulted primarily from (i) cash flows we generated from the operating profits earned totaling $66.0 million, which is our distributable net investment income, excluding the non-cash effects of the accretion of unearned income, payment-in-kind interest income, cumulative dividends and the amortization expense for deferred financing costs, (ii) cash proceeds totaling $235.6 million from the sales and repayments of debt investments and sales of and return on capital of equity investments and (iii) cash proceeds of $2.4 million related to changes in other assets and liabilities, partially offset by cash uses totaling $264.3 million for the funding of new portfolio company investments and settlement of accruals for portfolio investments existing as of December 31, 2019.

        The $26.4 million of cash used in our financing activities principally consisted of (i) $71.3 million in cash dividends paid to stockholders, (ii) $22.0 million in repayment of SBIC debentures, (iii) $1.8 million for purchases of vested restricted stock from employees to satisfy their tax withholding requirements upon the vesting of such restricted stock and (iv) $1.2 million for payment of deferred debt issuance costs, SBIC debenture fees and other costs, partially offset by (i) $29.9 million in net cash proceeds from our ATM Program (described below) and direct stock purchase plan, (ii) $25.0 million in cash proceeds from the issuance of SBIC debentures and (iii) $15.0 million in net proceeds from the Credit Facility.

    Capital Resources

        As of June 30, 2020, we had $68.5 million in cash and cash equivalents and $425.0 million of unused capacity under the Credit Facility, which we maintain to support our investment and operating activities. As of June 30, 2020, our net asset value totaled $1,370.9 million, or $20.85 per share.

        The Credit Facility, which provides additional liquidity to support our investment and operational activities, includes total commitments of $740.0 million from a diversified group of 18 lenders. The Credit Facility matures in September 2023 and contains an accordion feature which allows us to increase the total commitments under the facility to up to $800.0 million from new and existing lenders on the same terms and conditions as the existing commitments. Borrowings under the Credit Facility bear interest, subject to our election and resetting on a monthly basis on the first of each month, on a per annum basis at a rate equal to the applicable LIBOR rate (0.2% as of June 30, 2020) plus (i) 1.875% (or the applicable base rate (Prime Rate of 3.25% as of June 30, 2020) plus 0.875%) as long as we meet certain agreed upon excess collateral and maximum leverage requirements or (ii) 2.0% (or the applicable base rate plus 1.0%) otherwise. We pay unused commitment fees of 0.25% per annum on the unused lender commitments under the Credit Facility. The Credit Facility is secured by a first lien on the assets of MSCC and its subsidiaries, excluding the equity ownership or assets of the Funds and the External Investment Manager. The Credit Facility contains certain affirmative and negative covenants, including but not limited to: (i) maintaining a minimum availability of at least 10% of the borrowing base, (ii) maintaining an interest coverage ratio of at least 2.0 to 1.0, (iii) maintaining an asset coverage ratio (tangible net worth to Credit Facility borrowings) of at least 1.5 to 1.0 and (iv) maintaining a minimum tangible net worth. The Credit Facility is provided on a revolving basis through its final maturity date in September 2023, and contains two, one-year extension options which could extend the final maturity by up to two years, subject to certain conditions, including lender approval. As of June 30, 2020, we had $315.0 million in borrowings outstanding under the Credit Facility, the interest rate on the Credit Facility was 2.0% (based on the LIBOR rate of 0.2% as of the most recent reset date of June 1, 2020 plus 1.875%) and we were in compliance with all financial covenants of the Credit Facility.

        Through the Funds, we have the ability to issue SBIC debentures guaranteed by the SBA at favorable interest rates and favorable terms and conditions. Under existing SBIC regulations, SBA-approved SBICs under common control have the ability to issue debentures guaranteed by the SBA up to a regulatory maximum amount of $350.0 million. Under existing SBA-approved commitments, we had $314.8 million of outstanding SBIC debentures guaranteed by the SBA as of June 30, 2020 through our wholly owned SBICs, which bear a weighted-average annual fixed interest rate of approximately 3.5%, paid semiannually, and mature ten years from issuance. The first maturity related to our SBIC debentures occurs in 2020, and the weighted-average remaining duration is approximately 5.3 years as of June 30, 2020. During the six months ended June 30, 2020, Main Street issued $25.0 million of SBIC debentures and opportunistically prepaid $22.0 million of existing SBIC debentures that were scheduled to mature over the next year as part of an effort to manage the maturity dates of the oldest SBIC debentures. Debentures guaranteed by the SBA have fixed interest rates that equal prevailing 10-year Treasury Note rates plus a market spread and have a maturity of ten years with interest payable semiannually. The principal amount of the debentures is not required to be paid before maturity, but may be pre-paid at any time with no prepayment penalty. We expect to issue new SBIC debentures under the SBIC program in the future in an amount up to the regulatory maximum amount for affiliated SBIC funds.

        In November 2014, we issued $175.0 million in aggregate principal amount of 4.50% unsecured notes due 2019 (the "4.50% Notes due 2019") at an issue price of 99.53%. The 4.50% Notes due 2019 bore interest at a rate of 4.50% per year payable semiannually on June 1 and December 1 of each year. On December 2, 2019, we repaid the entire principal amount of the issued and outstanding 4.50% Notes due 2019, effective December 1, 2019 (the "Maturity Date"), at par value plus the accrued and unpaid interest thereon from June 1, 2019 through the Maturity Date.

        In November 2017, we issued $185.0 million in aggregate principal amount of 4.50% unsecured notes due December 1, 2022 (the "4.50% Notes due 2022") at an issue price of 99.16%. The 4.50% Notes due 2022 are unsecured obligations and rank pari passu with our current and future unsecured indebtedness; senior to any of our future indebtedness that expressly provides it is subordinated to the 4.50% Notes due 2022; effectively subordinated to all of our existing and future secured indebtedness, to the extent of the value of the assets securing such indebtedness, including borrowings under our Credit Facility; and structurally subordinated to all existing and future indebtedness and other obligations of any of our subsidiaries, including without limitation, the indebtedness of the Funds. The 4.50% Notes due 2022 may be redeemed in whole or in part at any time at our option subject to certain make-whole provisions. The 4.50% Notes due 2022 bear interest at a rate of 4.50% per year payable semiannually on June 1 and December 1 of each year. We may from time to time repurchase the 4.50% Notes due 2022 in accordance with the 1940 Act and the rules promulgated thereunder. As of June 30, 2020, the outstanding balance of the 4.50% Notes due 2022 was $185.0 million.

        The indenture governing the 4.50% Notes due 2022 (the "4.50% Notes due 2022 Indenture") contains certain covenants, including covenants requiring our compliance with (regardless of whether we are subject to) the asset coverage requirements set forth in Section 18(a)(1)(A) as modified by Section 61(a)(1) of the 1940 Act, as well as covenants requiring us to provide financial information to the holders of the 4.50% Notes due 2022 and the Trustee if we cease to be subject to the reporting requirements of the Exchange Act. These covenants are subject to limitations and exceptions that are described in the 4.50% Notes due 2022 Indenture.

        In April 2019, we issued $250.0 million in aggregate principal amount of 5.20% unsecured Notes due May 1, 2024 (the "5.20% Notes") at an issue price of 99.125%. Subsequently, in December 2019, we issued an additional $75.0 million of the 5.20% Notes at an issue price of 105.0%. The 5.20% Notes issued in December 2019 have identical terms as, and are a part of a single series with, the 5.20% Notes issued in April 2019. The aggregate net proceeds from the 5.20% Notes issuances were used to repay a portion of the borrowings outstanding under the Credit Facility. The 5.20% Notes are

unsecured obligations and rank pari passu with our current and future unsecured indebtedness; senior to any of our future indebtedness that expressly provides it is subordinated to the 5.20% Notes; effectively subordinated to all of our existing and future secured indebtedness, to the extent of the value of the assets securing such indebtedness, including borrowings under our Credit Facility; and structurally subordinated to all existing and future indebtedness and other obligations of any of our subsidiaries, including without limitation, the indebtedness of the Funds. The 5.20% Notes may be redeemed in whole or in part at any time at our option subject to certain make-whole provisions. The 5.20% Notes bear interest at a rate of 5.20% per year payable semiannually on May 1 and November 1 of each year. We may from time to time repurchase the 5.20% Notes in accordance with the 1940 Act and the rules promulgated thereunder. As of June 30, 2020, the outstanding balance of the 5.20% Notes was $325.0 million.

        The indenture governing the 5.20% Notes (the "5.20% Notes Indenture") contains certain covenants, including covenants requiring our compliance with (regardless of whether we are subject to) the asset coverage requirements set forth in Section 18(a)(1)(A) as modified by Section 61(a)(1) of the 1940 Act, as well as covenants requiring us to provide financial information to the holders of the 5.20% Notes and the Trustee if we cease to be subject to the reporting requirements of the Exchange Act. These covenants are subject to limitations and exceptions that are described in the 5.20% Notes Indenture.

        We maintain a program with certain selling agents through which we can sell shares of our common stock by means of at-the-market offerings from time to time (the "ATM Program"). During the six months ended June 30, 2020, we sold 907,515 shares of our common stock at a weighted-average price of $33.06 per share and raised $30.0 million of gross proceeds under the ATM Program. Net proceeds were $29.6 million after commissions to the selling agents on shares sold and offering costs. As of June 30, 2020, sales transactions representing 15,000 shares had not settled and are not included in shares issued and outstanding on the face of the consolidated balance sheet but are included in the weighted-average shares outstanding in the consolidated statement of operations and in the shares used to calculate net asset value per share. As of June 30, 2020, 7,451,635 shares remained available for sale under the ATM Program.

        During the year ended December 31, 2019, we sold 2,247,187 shares of our common stock at a weighted-average price of $40.05 per share and raised $90.0 million of gross proceeds under the ATM Program. Net proceeds were $88.8 million after commissions to the selling agents on shares sold and offering costs.

        We anticipate that we will continue to fund our investment activities through existing cash and cash equivalents, cash flows generated through our ongoing operating activities, utilization of available borrowings under our Credit Facility, and a combination of future issuances of debt and equity capital. Our primary uses of funds will be investments in portfolio companies, operating expenses and cash distributions to holders of our common stock.

        We periodically invest excess cash balances into marketable securities and idle funds investments. The primary investment objective of marketable securities and idle funds investments is to generate incremental cash returns on excess cash balances prior to utilizing those funds for investment in our LMM, Middle Market and Private Loan portfolio investments. Marketable securities and idle funds investments generally consist of debt investments, independently rated debt investments, certificates of deposit with financial institutions, diversified bond funds and publicly traded debt and equity investments.

        If our common stock trades below our net asset value per share, we will generally not be able to issue additional common stock at the market price, unless our stockholders approve such a sale and our Board of Directors makes certain determinations. We did not seek stockholder authorization to sell shares of our common stock below the then current net asset value per share of our common stock at

128


Table of Contents

our 2020 annual meeting of stockholders because our common stock price per share has generally traded significantly above the net asset value per share of our common stock since 2011. We would therefore need future approval from our stockholders to issue shares below the then current net asset value per share.

        In order to satisfy the Code requirements applicable to a RIC, we intend to distribute to our stockholders, after consideration and application of our ability under the Code to carry forward certain excess undistributed taxable income from one tax year into the next tax year, substantially all of our taxable income. In addition, as a BDC, we generally are required to meet a coverage ratio of total assets to total senior securities, which include borrowings and any preferred stock we may issue in the future, of at least 200% (or 150% if certain requirements are met). This requirement limits the amount that we may borrow. In January 2008, we received an exemptive order from the SEC to exclude SBA-guaranteed debt securities issued by MSMF and any other wholly owned subsidiaries of ours which operate as SBICs from the asset coverage requirements of the 1940 Act as applicable to us, which, in turn, enables us to fund more investments with debt capital.

        Although we have been able to secure access to additional liquidity, including through the Credit Facility, public debt issuances, leverage available through the SBIC program and equity offerings, there is no assurance that debt or equity capital will be available to us in the future on favorable terms, or at all.

    Recently Issued or Adopted Accounting Standards

        In August 2018, the SEC adopted rules (the "SEC Release") amending certain disclosure requirements intended to eliminate redundant, duplicative, overlapping, outdated or superseded, in light of other SEC disclosure requirements, U.S. GAAP requirements or changes in the information environment. In part, the SEC Release requires an investment company to present distributable earnings in total on the consolidated balance sheet and consolidated statements of changes in net assets, rather than showing the three components of distributable earnings as previously shown. We adopted this part of the SEC Release during the year ended December 31, 2018. The impact of the adoption of these rules on our consolidated financial statements was not material. Additionally, the SEC Release requires disclosure of changes in net assets within a registrant's Form 10-Q filing on a quarter-to-date and year-to-date basis for both the current year and prior year comparative periods. We adopted the new requirement to present changes in net assets in interim financial statements within Form 10-Q filings effective January 1, 2019. The adoption of these rules did not have a material impact on the consolidated financial statements.

        In March 2020, the FASB issued ASU 2020-04, "Reference rate reform (Topic 848)—Facilitation of the effects of reference rate reform on financial reporting." The amendments in this update provide optional expedients and exceptions for applying U.S. GAAP to certain contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform and became effective upon issuance for all entities. We have agreements that have LIBOR as a reference rate with certain portfolio companies and also with certain lenders. Many of these agreements include language for choosing an alternative successor rate if LIBOR reference is no longer considered to be appropriate. Contract modifications are required to be evaluated in determining whether the modifications result in the establishment of new contracts or the continuation of existing contracts. We adopted this amendment in March 2020 and plan to apply the amendments in this update to account for contract modifications due to changes in reference rates. We do not believe that it will have a material impact on its consolidated financial statements and disclosures.

        In May 2020, the SEC adopted rules Release No. 33-10786 (the "Release"), Amendments to Financial Disclosures about Acquired and Disposed Businesses, amending Rule 1-02(w)(2) used in the determination of a significant subsidiary. In part, the Release eliminated the use of the asset test, and

129


Table of Contents

amended the income and investment tests for determining whether an unconsolidated subsidiary requires additional disclosure in the footnotes of the financial statements. We adopted the Release during the quarter ended June 30, 2020. The impact of the adoption of these rules on our consolidated financial statements was not material.

        From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that are adopted by us as of the specified effective date. We believe that the impact of recently issued standards and any that are not yet effective will not have a material impact on our consolidated financial statements upon adoption.

    Inflation

        Inflation has not had a significant effect on our results of operations in any of the reporting periods presented herein. However, our portfolio companies have experienced, and may in the future experience, the impacts of inflation on their operating results, including periodic escalations in their costs for labor, raw materials and third-party services and required energy consumption.

    Off-Balance Sheet Arrangements

        We may be a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financial needs of our portfolio companies. These instruments include commitments to extend credit and fund equity capital and involve, to varying degrees, elements of liquidity and credit risk in excess of the amount recognized in the balance sheet. At June 30, 2020, we had a total of $108.7 million in outstanding commitments comprised of (i) thirty-eight investments with commitments to fund revolving loans that had not been fully drawn or term loans with additional commitments not yet funded and (ii) ten investments with equity capital commitments that had not been fully called.

    Contractual Obligations

        As of June 30, 2020, the future fixed commitments for cash payments in connection with our SBIC debentures, the 4.50% Notes due 2022, the 5.20% Notes and rent obligations under our office lease for each of the next five years and thereafter are as follows:

Operating Lease Obligation means a rent payment obligation under a lease classified as an operating lease and disclosed pursuant to ASC 842, as may be modified or supplemented.

        As of June 30, 2020, we had $315.0 million in borrowings outstanding under our Credit Facility, and the Credit Facility is currently scheduled to mature in September 2023. The Credit Facility contains two, one-year extension options which could extend the maturity to September 2025, subject to lender

approval. See further discussion of the Credit Facility terms in "—Liquidity and Capital Resources—Capital Resources."

    Related Party Transactions

        As discussed further above, the External Investment Manager is treated as a wholly owned portfolio company of MSCC and is included as part of our Investment Portfolio. At June 30, 2020, we had a receivable of approximately $4.8 million due from the External Investment Manager, which included approximately $3.8 million related primarily to operating expenses incurred by us as required to support the External Investment Manager's business and amounts due from the External Investment Manager to Main Street under a tax sharing agreement (see further discussion above in "—Critical Accounting Policies—Income Taxes") and approximately $1.1 million of dividends declared but not paid by the External Investment Manager.

        In November 2015, our Board of Directors approved and adopted the Main Street Capital Corporation Deferred Compensation Plan (the "2015 Deferred Compensation Plan"). The 2015 Deferred Compensation Plan became effective on January 1, 2016 and replaced the Deferred Compensation Plan for Non-Employee Directors previously adopted by the Board of Directors in June 2013 (the "2013 Deferred Compensation Plan"). Under the 2015 Deferred Compensation Plan, non-employee directors and certain key employees may defer receipt of some or all of their cash compensation and directors' fees, subject to certain limitations. Individuals participating in the 2015 Deferred Compensation Plan receive distributions of their respective balances based on predetermined payout schedules or other events as defined by the plan and are also able to direct investments made on their behalf among investment alternatives permitted from time to time under the plan, including phantom Main Street stock units. As of June 30, 2020, $9.9 million of compensation and directors' fees had been deferred under the 2015 Deferred Compensation Plan (including amounts previously deferred under the 2013 Deferred Compensation Plan). Of this amount, $5.0 million was deferred into phantom Main Street stock units, representing 152,633 shares of our common stock. Including phantom stock units issued through dividend reinvestment and net of any shares distributed, the phantom stock units outstanding as of June 30, 2020 represented 154,179 shares of our common stock. Any amounts deferred under the plan represented by phantom Main Street stock units will not be issued or included as outstanding on the consolidated statements of changes in net assets until such shares are actually distributed to the participant in accordance with the plan, but the related phantom stock units are included in weighted-average shares outstanding with the related dollar amount of the deferral included in total expenses in Main Street's consolidated statements of operations as earned. The dividend amounts related to additional phantom stock units are included in the statements of changes in net assets as an increase to dividends to stockholders offset by a corresponding increase to additional paid-in capital.

    Recent Developments

        During August 2020, we declared regular monthly dividends of $0.205 per share for each month of October, November and December of 2020. These regular monthly dividends equal a total of $0.615 per share for the fourth quarter of 2020, unchanged from the regular monthly dividends paid in the fourth quarter of 2019. Including the regular monthly dividends declared for the third and fourth quarters of 2020, we will have paid $29.60 per share in cumulative dividends since our October 2007 initial public offering.

        In July 2020, we announced that the External Investment Manager had entered into a definitive asset purchase agreement (the "HMS Purchase Agreement") under which it will become the sole investment adviser and administrator to HMS Income, subject to certain closing conditions. The parties expect the transaction to be completed in the fourth quarter of 2020. Following the closing of the transaction, the External Investment Manager will replace HMS Adviser as the investment adviser and

131


Table of Contents

administrator to HMS Income. The base management fee rate under the External Investment Manager's proposed new investment advisory agreement with HMS Income, which has been unanimously approved by the board of directors of HMS Income, will be reduced from 2.00% to 1.75%, with no changes to the incentive fee calculations. The consummation of the transactions contemplated by the asset purchase agreement is subject to approval of the new investment advisory agreement by stockholders of HMS Income and other customary closing conditions. Post-closing, HMS Income is expected to change its name to MSC Income Fund, Inc.

        In July 2020, we issued an additional $125.0 million aggregate principal amount of the 5.20% Notes at an issue price of 102.674%, for total net proceeds to us, resulting from the issue price and after underwriting discounts and estimated offering expenses payable by us, of approximately $127.3 million. Following the issuance of the additional $125.0 million aggregate principal amount of the 5.20% Notes in July 2020, the outstanding principal balance of the 5.20% Notes was $450.0 million. The 5.20% Notes issued in July 2020 have identical terms as, and are a part of a single series with, the 5.20% Notes issued in April 2019 and in December 2019. The aggregate net proceeds from the 5.20% Notes issuances were used to repay a portion of the borrowings outstanding under the Credit Facility.

Item 3.    Quantitative and Qualitative Disclosures about Market Risk

        We are subject to financial market risks, including changes in interest rates, and changes in interest rates may affect both our interest expense on the debt outstanding under our Credit Facility and our interest income from portfolio investments. Our risk management systems and procedures are designed to identify and analyze our risk, to set appropriate policies and limits and to continually monitor these risks. Our investment income will be affected by changes in various interest rates, including LIBOR and prime rates, to the extent that any debt investments include floating interest rates. See "Risk Factors—Risks Relating to Our Business and Structure -The interest rates of our floating-rate loans to our portfolio companies and for any of our borrowings that extend beyond 2021 might be subject to change based on recent regulatory changes" included in our Form 10-K for the fiscal year ended December 31, 2019 for more information regarding risks associated with our debt investments and borrowings that utilize LIBOR as a reference rate.

        The majority of our debt investments are made with either fixed interest rates or floating rates that are subject to contractual minimum interest rates for the term of the investment. As of June 30, 2020, approximately 71% of our debt investment portfolio (at cost) bore interest at floating rates, 84% of which were subject to contractual minimum interest rates. Our interest expense will be affected by changes in the published LIBOR rate in connection with our Credit Facility; however, the interest rates on our outstanding SBIC debentures, 4.50% Notes due 2022 and 5.20% Notes, which collectively comprise the majority of our outstanding debt, are fixed for the life of such debt. As of June 30, 2020, we had not entered into any interest rate hedging arrangements. Due to our limited use of derivatives, we have claimed an exclusion from the definition of the term "commodity pool operator" under the Commodity Exchange Act and, therefore, are not subject to registration or regulation as a pool operator under such Act. The following table shows the approximate annualized increase or decrease in

the components of net investment income due to hypothetical base rate changes in interest rates, assuming no changes in our investments and borrowings as of June 30, 2020.

        The hypothetical results assume that all LIBOR and prime rate changes would be effective on the first day of the period. However, the contractual LIBOR and prime rate reset dates would vary throughout the period, on either a monthly or quarterly basis, for both our investments and our Credit Facility. The hypothetical results would also be impacted by the changes in the amount of debt outstanding under our Credit Facility (with an increase (decrease) in the debt outstanding under the Credit Facility resulting in an (increase) decrease in the hypothetical interest expense).

Item 4.    Controls and Procedures

        As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer, President, Chief Financial Officer, Chief Compliance Officer and Chief Accounting Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15 of the Exchange Act). Based on that evaluation, our Chief Executive Officer, President, Chief Financial Officer, Chief Compliance Officer and Chief Accounting Officer have concluded that our current disclosure controls and procedures are effective in timely alerting them of material information relating to us that is required to be disclosed in the reports we file or submit under the Exchange Act. There have been no changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting despite the fact that many of our employees are working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the COVID-19 situation on our internal controls to minimize the impact on their design and operating effectiveness.

PART II—OTHER INFORMATION

Item 1.    Legal Proceedings

        We may, from time to time, be involved in litigation arising out of our operations in the normal course of business or otherwise. Furthermore, third parties may seek to impose liability on us in connection with the activities of our portfolio companies. While the outcome of any current legal proceedings cannot at this time be predicted with certainty, we do not expect any current matters will materially affect our financial condition or results of operations; however, there can be no assurance whether any pending legal proceedings will have a material adverse effect on our financial condition or results of operations in any future reporting period.

Item 1A.    Risk Factors

        You should carefully consider the risks described below and all other information contained in this Quarterly Report on Form 10-Q, including our interim financial statements and the related notes thereto, before making a decision to purchase our securities. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may have a material adverse effect on our business, financial condition and/or operating results, as well as the market price of our securities.

        In addition to the other information set forth in this report, you should carefully consider the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019 that we filed with the SEC on February 28, 2020 and in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020 that we filed with the SEC on May 8, 2020, which could materially affect our business, financial condition or operating results.

We cannot assure you that the transactions contemplated by the HMS Purchase Agreement will close, and any failure of the closing to occur could have a material adverse effect on our business, financial condition and results of operations.

        The closing of the transactions contemplated by the HMS Purchase Agreement is conditioned on: (i) the requisite approval of the External Investment Manager's new investment advisory agreement by HMS Income's stockholders; (ii) the resignations of certain current members of the HMS Income board of directors and the appointment to the board of directors of two new disinterested directors so that at least seventy-five percent (75%) of the members of the board of directors are not interested directors; (iii) the resignation of the Company's existing officers and the election or appointment of Dwayne L. Hyzak as Chief Executive Officer, Brent D. Smith as Chief Financial Officer and Jason B. Beauvais as Senior Vice President, General Counsel and Chief Compliance Officer; (iv) the receipt of consents from HMS Income's lenders under two credit facilities; (v) the release of any liens on the HMS Adviser's assets; (vi) HMS Income's entry into a non-exclusive, royalty-free license agreement with Main Street to use the name "Main Street," "MSC" or similar derivations thereof in HMS Income's name; and (vii) other customary closing conditions, including that there has been no material adverse effect. We cannot assure you of the timing of the closing of the transactions contemplated by the HMS Purchase Agreement and whether and when the new investment advisory agreement will be effective. Any failure of the closing to occur could have a material adverse effect on our business, financial condition and results of operations.

Item 2.    Unregistered Sales of Equity Securities and Use of Proceeds

        During the three months ended June 30, 2020, we issued 146,229 shares of our common stock under our dividend reinvestment plan. These issuances were not subject to the registration requirements of the Securities Act of 1933, as amended. The aggregate value of the shares of common

134


Table of Contents

stock issued during the three months ended June 30, 2020 under the dividend reinvestment plan was approximately $4.2 million.

        Upon vesting of restricted stock awarded pursuant to our employee equity compensation plan, shares may be withheld to meet applicable tax withholding requirements. Any withheld shares are treated as common stock purchases by the Company in our consolidated financial statements as they reduce the number of shares received by employees upon vesting (see "Purchase of vested stock for employee payroll tax withholding" in the consolidated statements of changes in net assets for share amounts withheld).
