ORGANIZATION
Main Street Capital Corporation ("MSCC" or, together with its consolidated subsidiaries, "Main Street" or the "Company") is a principal investment firm primarily focused on providing customized long-term debt and equity capital solutions to lower middle market ("LMM") companies (its "LMM investment strategy") and debt capital to private ("Private Loan") companies owned by or in the process of being acquired by a private equity fund (its "Private Loan investment strategy"). Main Street's portfolio investments are typically made to support management buyouts, recapitalizations, growth financings, refinancings and acquisitions of companies that operate in diverse industry sectors. Main Street seeks to partner with entrepreneurs, business owners and management teams and generally provides "one-stop" debt and equity financing solutions within its LMM investment strategy. Main Street invests primarily in secured debt investments, equity investments, warrants and other securities of LMM companies typically based in the United States. Main Street also seeks to partner with private equity fund sponsors in its Private Loan investment strategy and primarily invests in secured debt investments of Private Loan companies generally headquartered in the United States.
Main Street also maintains a legacy portfolio of investments in larger middle market ("Middle Market") companies (its "Middle Market investment portfolio") and a limited portfolio of other portfolio ("Other Portfolio") investments. Main Street's Middle Market investments are generally debt investments in companies owned by a private equity fund that were originally issued through a syndication financing process. Main Street has generally stopped making new Middle Market investments and expects the size of its Middle Market investment portfolio to continue to decline in future periods as its existing Middle Market investments are repaid or sold. Main Street's Other Portfolio investments primarily consist of investments that are not consistent with the typical profiles for its LMM, Private Loan or Middle Market portfolio investments, including investments in unaffiliated investment companies and private funds managed by third parties.
The "Investment Portfolio," as used herein, refers to all of Main Street's investments in LMM portfolio companies, investments in Private Loan portfolio companies, investments in Middle Market portfolio companies, Other Portfolio investments, short-term portfolio investments (as discussed in Note C - Fair Value Hierarchy for Investments - Portfolio Composition - Investment Portfolio Compositionin the notes to the consolidated financial statements included inItem 1. Consolidated Financial Statementsof this Quarterly Report on Form 10-Q) and the investment in the External Investment Manager (as defined below).
Table of contents
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"). 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.
MSCC wholly owns several investment funds, including Main Street Mezzanine Fund, LP ("MSMF") and Main Street Capital III, LP ("MSC III" and, together with MSMF, 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").
MSC Adviser I, LLC (the "External Investment Manager") was formed in November 2013 as a wholly-owned subsidiary of Main Street to provide investment management and other services to parties other than Main Street ("External Parties") and earns 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 Main Street and is not included as a consolidated subsidiary in Main Street'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 does 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. MSCC also has certain direct and indirect wholly-owned subsidiaries formed for financing purposes (the "Structured Subsidiaries").
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, the Taxable Subsidiaries and the Structured Subsidiaries.
OVERVIEW OF OUR BUSINESS
Our principal investment objective is to maximize our Investment Portfolio's total return by generating current income from our debt investments and current income 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. We seek to achieve our investment objective primarily through our LMM and Private Loan investment strategies. Our LMM investment strategy involves investments in companies that generally have annual revenues between $10 million and $150 million and annual earnings before interest, tax, depreciation and amortization expenses ("EBITDA") between $3 million and $20 million. Our LMM portfolio investments generally range in size from $5 million to $125 million. Our Private Loan investment strategy involves investments in companies that generally have annual revenues between $25 million and $500 million and annual EBITDA between $7.5 million and $50 million. Our Private Loan investments generally range in size from $10 million to $100 million.
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 participation. 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. We believe that providing customized, "one-stop" financing solutions is important and valuable to LMM portfolio companies. We generally seek to partner directly with entrepreneurs, management teams and business owners in making our LMM investments. Our LMM portfolio debt investments are generally secured by a first priority lien on the assets of the portfolio company and typically have a term of between five and seven years from the original investment date.
Table of contents
Private Loan investments primarily consist of debt securities that have primarily been originated directly by us or, to a lesser extent, through our strategic relationships with other investment funds on a collaborative basis through investments that are often referred to in the debt markets as "club deals" because of the small lender group size. In both cases, our Private Loan investments are typically made in a company owned by or in the process of being acquired by a private equity fund. Our Private Loan portfolio debt investments are generally secured by a first 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. We may also co-invest with the private equity fund in the equity securities of our Private Loan portfolio companies.
We also maintain a legacy portfolio of investments in larger Middle Market companies. Our Middle Market investments are generally debt investments in companies owned by a private equity fund that were originally issued through a syndication financing process. We have generally stopped making new Middle Market investments and expect the size of our Middle Market investment portfolio to continue to decline in future periods as existing Middle Market investments are repaid or sold. Our Middle Market debt investments generally range in size from $3 million to $25 million, are generally secured by a first 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 Other Portfolio investments primarily consist of investments that are not consistent with the typical profiles for our LMM, Private Loan or Middle Market 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.
Based upon our liquidity and capital structure management activities, our Investment Portfolio may also periodically include short-term portfolio investments that are atypical of our LMM and Private Loan portfolio investments in that they are intended to be a short-term deployment of capital. These assets are typically expected to be realized in one year or less and are not expected to be a significant portion of our overall Investment Portfolio.
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.
Our portfolio investments are generally made through MSCC, the Taxable Subsidiaries, the Funds and the Structured Subsidiaries. MSCC, the Taxable Subsidiaries, the Funds and the Structured Subsidiaries share the same investment strategies and criteria, although they are subject to different regulatory regimes. An investor's return in MSCC will depend, in part, on the Taxable Subsidiaries', the Funds' and the Structured Subsidiaries' 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.
Table of contents
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 better alignment of interests between our management team and our employees and our stockholders and 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 and our External Investment Manager's asset management business (as described below). The ratio of our total operating expenses, excluding interest expense, as a percentage of our quarterly average total assets was 1.3% for each of the trailing twelve months ended September 30, 2025 and 2024 and for the year ended December 31, 2024. The ratio of our total operating expenses, including interest expense, as a percentage of our quarterly average total assets was 3.8% and 3.7% for the trailing twelve months ended September 30, 2025 and 2024, respectively, and 3.8% for the year ended December 31, 2024. Our ratio of expenses as a percentage of our average net asset value ("NAV") is described in greater detail in Note F - Financial Highlightsin the notes to the consolidated financial statements included in Item 1. Consolidated Financial Statementsof this Quarterly Report on Form 10-Q.
The External Investment Manager serves as the investment adviser and administrator to MSC Income Fund, Inc. ("MSC Income") pursuant to an Investment Advisory and Administrative Services Agreement entered into in October 2020 between the External Investment Manager and MSC Income (as amended and restated on January 29, 2025, the "Advisory Agreement"). Under the Advisory Agreement, prior to January 29, 2025, the External Investment Manager earned a 1.75% annual base management fee on MSC Income's average total assets, a subordinated incentive fee on income equal to 20% of pre-incentive fee net investment income above a specified investment return hurdle rate and a 20% incentive fee on cumulative net realized capital gains in exchange for providing advisory services to MSC Income. On and after January 29, 2025, under the Advisory Agreement, the External Investment Manager earns a 1.5% annual base management fee on MSC Income's average total assets (including cash and cash equivalents), payable quarterly in arrears (with additional future contractual reductions based upon changes to MSC Income's investment portfolio composition), a subordinated incentive fee on income equal to 17.5% of pre-incentive fee net investment income above a specified investment return hurdle rate, subject to a 50% / 50% catch-up feature, and a 17.5% incentive fee on cumulative net realized capital gains from January 29, 2025.
Additionally, the External Investment Manager has entered into investment management agreements with MS Private Loan Fund I, LP ("Private Loan Fund I") and MS Private Loan Fund II, LP ("Private Loan Fund II"), each a private investment fund with a strategy to co-invest with Main Street in Private Loan portfolio investments, pursuant to which the External Investment Manager provides investment advisory and management services to each fund in exchange for an asset-based management fee and certain incentive fees. The External Investment Manager may also advise other clients, including funds and separately managed accounts, pursuant to advisory and services agreements with such clients in exchange for asset-based and incentive fees.
The External Investment Manager earns management fees based on the assets of the funds and accounts under management and may earn incentive fees, or a carried interest, based on the performance of the funds and accounts managed. For the three months ended September 30, 2025 and 2024, the External Investment Manager earned $5.6 million and $6.1 million in base management fees, respectively, $3.9 million and $2.4 million in incentive fees, respectively, and $0.2 million of administrative service fee income for each of the three months ended September 30, 2025 and 2024. For the nine months ended September 30, 2025 and 2024, the External Investment Manager earned $17.1 million and $17.7 million in base management fees, respectively, $10.3 million and $10.4 million in incentive fees, respectively, and $0.5 million of administrative service fee income for each of the nine months ended September 30, 2025 and 2024.
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 MSC Income and its other clients. 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 September 30, 2025 and 2024 are net of expenses allocated to the External Investment Manager of $5.7 million and $5.3 million, respectively. Our total expenses for the nine months ended September 30, 2025 and 2024 are net of expenses allocated to the External Investment Manager of $17.0 million and $16.8 million, respectively.
Table of contents
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 September 30, 2025 and 2024, dividends accrued by us from the External Investment Manager were $3.0 million and $2.6 million, respectively. For the three months ended September 30, 2025 and 2024, the total contribution of the External Investment Manager to our net investment income was $8.8 million and $7.9 million, respectively. For the nine months ended September 30, 2025 and 2024, dividends accrued by us from the External Investment Manager were $8.4 million and $8.9 million, respectively. For the nine months ended September 30, 2025 and 2024, the total contribution of the External Investment Manager to our net investment income was $25.4 million and $25.6 million, respectively.
We have received an exemptive order from the SEC permitting co-investments among us, MSC Income and other advisory clients of the External Investment Manager in certain negotiated transactions where co-investing would otherwise be prohibited under the 1940 Act. We have made co-investments with, and in the future intend to continue to make co-investments with MSC Income, Private Loan Fund I, Private Loan Fund II and other advisory clients of the External Investment Manager, 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 us and the External Investment Manager's advised clients, as applicable, and if it is appropriate, to propose an allocation of the investment opportunity between such parties. Because the External Investment Manager may earn performance-based fee compensation from its advisory clients, this may provide the Company and the External Investment Manager an incentive to allocate opportunities to advisory clients instead of us. However, both we and the External Investment Manager have policies and procedures in place to manage this conflict, including approval of investment allocations and oversight of co-investments by the independent members of our Board of Directors. In addition to the co-investment program described above, we also co-invest in certain investment transactions where price is the only negotiated point by us and our affiliates.
INVESTMENT PORTFOLIO SUMMARY
The following tables provide a summary of our investments in the LMM and Private Loan portfolios as of September 30, 2025 and December 31, 2024 (this information excludes Middle Market, Other Portfolio investments and the External Investment Manager, which are discussed further below).
As of September 30, 2025
LMM (a) Private Loan
(dollars in millions)
Number of portfolio companies 88 86
Fair value $ 2,782.2 $ 1,886.5
Cost $ 2,167.5 $ 1,898.3
Debt investments as a % of portfolio (at cost) 70.7 % 94.0 %
Equity investments as a % of portfolio (at cost) 29.3 % 6.0 %
% of debt investments at cost secured by first priority lien 99.3 % 99.9 %
Weighted-average annual effective yield (b) 12.7 % 11.1 %
Average EBITDA (c) $ 10.3 $ 34.3
___________________________
(a)As of September 30, 2025, we had equity ownership in all of our LMM portfolio companies, and the average fully diluted equity ownership in those portfolio companies was 38%.
(b)The weighted-average annual effective yields were computed using the effective interest rates for all debt investments as of September 30, 2025, 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, and are weighted based upon the principal amount of each applicable debt investment as of September 30, 2025. The weighted-average annual effective yield on our debt portfolio as of September 30, 2025, including debt investments on non-accrual status, was 12.1% for our LMM portfolio and 10.1% for our Private Loan portfolio. The weighted-average annual effective yield is not reflective of what an investor in shares of our common stock will realize on its investment because it does not reflect changes in the market value of our stock, our utilization of debt capital in our capital structure, our expenses or any sales load paid by an investor.
Table of contents
(c)The average EBITDA is calculated using a simple average for the LMM portfolio and a weighted-average for the Private Loan portfolio. These calculations exclude certain portfolio companies, including five LMM portfolio companies and six 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 and those portfolio companies whose primary operations have ceased and only residual value remains.
As of December 31, 2024
LMM (a) Private Loan
(dollars in millions)
Number of portfolio companies 84 91
Fair value $ 2,502.9 $ 1,904.3
Cost $ 1,937.8 $ 1,952.5
Debt investments as a % of portfolio (at cost) 70.8 % 95.4 %

___________________________
(a)As of December 31, 2024, we had equity ownership in all of our LMM portfolio companies, and the average fully diluted equity ownership in those portfolio companies was 38%.
(b)The weighted-average annual effective yields were computed using the effective interest rates for all debt investments as of December 31, 2024, 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, and are weighted based upon the principal amount of each applicable debt investment as of December 31, 2024. The weighted-average annual effective yield on our debt portfolio as of December 31, 2024, including debt investments on non-accrual status, was 12.3% for our LMM portfolio and 11.5% for our Private Loan portfolio. The weighted-average annual effective yield is not reflective of what an investor in shares of our common stock will realize on its investment because it does not reflect changes in the market value of our stock, our utilization of debt capital in our capital structure, 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 Private Loan portfolio. These calculations exclude certain portfolio companies, including five LMM portfolio companies and five 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 and those portfolio companies whose primary operations have ceased and only residual value remains.
For the three months ended September 30, 2025 and 2024, we achieved an annualized total return on investments of 16.9% and 17.7%, respectively. For the nine months ended September 30, 2025 and 2024, we achieved an annualized total return on investments of 16.4% and 16.7%, respectively. For the year ended December 31, 2024, we achieved a total return on investments of 17.9%. Total return on investments is calculated using the interest, dividend and fee income, as well as the realized and unrealized change in fair value of the Investment Portfolio for the specified period. Our total return on investments is not reflective of what an investor in shares of our common stock will realize on its investment because it does not reflect changes in the market value of our stock, our utilization of debt capital in our capital structure, our expenses or any sales load paid by an investor.
As of September 30, 2025, we had Other Portfolio investments in 32 entities, spread across 12 investment managers, collectively totaling $122.8 million in fair value and $130.9 million in cost basis, which comprised 2.4% and 3.0% of our Investment Portfolio at fair value and cost, respectively. As of December 31, 2024, we had Other Portfolio investments in 31 entities, spread across 12 investment managers, collectively totaling $124.1 million in fair value and $122.5 million in cost basis, which comprised 2.5% and 2.9% of our Investment Portfolio at fair value and cost, respectively.
As of September 30, 2025, we had Middle Market portfolio investments in 11 portfolio companies, collectively totaling $89.9 million in fair value and $119.8 million in cost basis, which comprised 1.7% and 2.8% of our Investment Portfolio at fair value and cost, respectively. As of December 31, 2024, we had Middle Market portfolio investments in 15 portfolio companies, collectively totaling $155.3 million in fair value and $195.0 million in cost basis, which comprised 3.1% and 4.6% of our Investment Portfolio at fair value and cost, respectively.
Table of contents
As previously discussed in Note A.1. - Organization and Basis of Presentation - Organization in the notes to the consolidated financial statements included in Item 1. Consolidated Financial Statementsof this Quarterly Report on Form 10-Q, we hold an investment in the External Investment Manager, a wholly-owned subsidiary that is treated as a portfolio investment. As of September 30, 2025, this investment had a fair value of $266.4 million and a cost basis of $29.5 million, which comprised 5.2% and 0.7% of our Investment Portfolio at fair value and cost, respectively. As of December 31, 2024, this investment had a fair value of $246.0 million and a cost basis of $29.5 million, which comprised 5.0% and 0.7% of our Investment Portfolio at fair value and cost, respectively.
CRITICAL ACCOUNTING POLICIES
The preparation of financial statements and related disclosures in conformity with generally accepted accounting principles ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the periods reported. Actual results could materially differ from those estimates. Critical accounting policies are those that require management to make subjective or complex judgments about the effect of matters that are inherently uncertain and may change in subsequent periods. Changes that may be required in the underlying assumptions or estimates in these areas could have a material impact on our current and future financial condition and results of operations.
Management has discussed the development and selection of each critical accounting policy and estimate with the Audit Committee of the Board of Directors. Our critical accounting policies and estimates include the Investment Portfolio Valuation and Revenue Recognition policies described below. Our significant accounting policies are described in greater detail in Note B - Summary of Significant Accounting Policiesin the notes to the consolidated financial statements included in Item 1. Consolidated Financial Statementsof this Quarterly Report on Form 10-Q.
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. We consider this determination to be a critical accounting estimate, given the significant judgments and subjective measurements required. As of September 30, 2025 and December 31, 2024, our Investment Portfolio valued at fair value represented 97% and 96%, respectively, of our total assets. We are required to report our investments at fair value. We follow the provisions of Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("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. - Summary of Significant Accounting Policies - Valuation of the Investment Portfolio in the notes to the consolidated financial statements included in Item 1. Consolidated Financial Statementsof this Quarterly Report on Form 10-Q 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.
Rule 2a-5 under the 1940 Act permits a BDC's board of directors to designate its executive officers or investment adviser as a valuation designee to determine the fair value for its investment portfolio, subject to the active oversight of the board. Our Board of Directors has approved policies and procedures pursuant to Rule 2a-5 (the "Valuation Procedures") and has designated a group of our executive officers to serve as the Board of Directors' valuation designee. We believe our Investment Portfolio as of September 30, 2025 and December 31, 2024 approximates fair value as of those dates based on the markets in which we operate and other conditions in existence on those reporting dates.
Table of contents
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. 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 its debt obligation, 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 obligation, 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 generally deferred and accreted into income over the life of the financing.
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 in Note B.10. - Summary of Significant Accounting Policies - Income Taxesin the notes to the consolidated financial statements included in Item 1. Consolidated Financial Statementsof this Quarterly Report on Form 10-Q), 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 September 30, 2025 and 2024, (i) 3.0% and 4.4%, respectively, of our total investment income was attributable to PIK interest income not paid currently in cash and (ii) 0.7% and 0.5%, respectively, of our total investment income was attributable to cumulative dividend income not paid currently in cash. For the nine months ended September 30, 2025 and 2024, (i) 2.7% and 3.8%, respectively, of our total investment income was attributable to PIK interest income not paid currently in cash and (ii) 0.7% and 0.4%, respectively, of our total investment income was attributable to cumulative dividend income not paid currently in cash.

INVESTMENT PORTFOLIO COMPOSITION
The following tables summarize the composition of our total combined LMM, Private Loan and Middle Market portfolio investments at cost and fair value by type of investment as a percentage of the total combined LMM, Private Loan and Middle Market portfolio investments as of September 30, 2025 and December 31, 2024 (this information excludes Other Portfolio investments and the External Investment Manager, which are discussed above).

Our LMM, Private Loan and Middle Market 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 Item 1A. Risk Factorscontained in Part II of this Form 10-Q for further information.
PORTFOLIO ASSET QUALITY
We utilize an internally developed investment rating system to rate the performance of each LMM, Private Loan and Middle Market portfolio company and to monitor our expected level of returns on each of our LMM, Private Loan and Middle Market investments in relation to our expectations for the portfolio company. The investment rating system takes into consideration various factors, including, but not limited to, 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 September 30, 2025, investments on non-accrual status comprised 1.2% of our total Investment Portfolio at fair value and 3.6% at cost. As of December 31, 2024, investments on non-accrual status comprised 0.9% of our total Investment Portfolio at fair value and 3.5% at 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, 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.

(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 and deferred compensation expense or benefit. We believe presenting distributable net investment income and the related per share amounts is useful and appropriate supplemental disclosure for analyzing our financial performance since share-based compensation does not require settlement in cash and deferred compensation expense or benefit does not result in a net cash impact to Main Street upon settlement. However, distributable net investment income is a non-U.S. GAAP measure and should not be considered as a replacement for net investment income or other earnings measures presented in accordance with U.S. GAAP and 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 detailed in the table above.

(b)Distributable net investment income before taxes is net investment income as determined in accordance with U.S. GAAP, excluding the impact of share-based compensation expense, deferred compensation expense or benefit and any tax expenses included in net investment income. We believe presenting distributable net investment income before taxes and the related per share amounts is useful and appropriate supplemental disclosure for analyzing our financial performance since share-based compensation does not require settlement in cash and deferred compensation expense or benefit does not result in a net cash impact to Main Street upon settlement, and since tax expenses included in net investment income may include excise tax expense, which is not solely attributable to net investment income, and deferred taxes, which are not payable in the current period. However, distributable net investment income before taxes is a non-U.S. GAAP measure and should not be considered as a replacement for net investment income, net investment income before taxes or other earnings measures presented in accordance with U.S. GAAP and should be reviewed only in connection with such U.S. GAAP measures in analyzing our financial performance.

Investment Income
Total investment income for the three months ended September 30, 2025 was $139.8 million, a 2% increase from the $136.8 million of total investment income for the corresponding period of 2024. The following table provides a summary of the changes in the comparable period activity.

(a)The decrease in interest income was principally attributable to (i) a decrease in interest rates, primarily resulting from decreases in benchmark index interest rates on floating rate Investment Portfolio debt investments and decreases in interest rate spreads on existing Investment Portfolio debt investments and (ii) an increase in investments on non-accrual status, partially offset by higher average levels of income producing Investment Portfolio debt investments.
(b)The increase in dividend income was primarily a result of dividend income increases of (i) $6.6 million from our LMM portfolio companies, (ii) $0.7 million from our Other Portfolio investments and (iii) $0.5 million from our External Investment Manager.
(c)The increase in fee income was primarily due to a $1.4 million increase in fees related to increased investment activity and a $0.9 million increase from the refinancing and prepayment of Investment Portfolio debt investments.
(d)The increase in total investment income includes a net increase of $2.1 million in certain income considered less consistent or non-recurring, including (i) a $0.9 million increase in such fee income, (ii) a $0.6 million increase in such dividend income and (iii) a $0.6 million increase in such interest income from accelerated prepayment, repricing and other activity related to certain Investment Portfolio debt investments.

(a)The increase in cash compensation was primarily attributable to (i) increased incentive compensation accruals, (ii) increased base compensation rates and (iii) increased headcount to support our growing Investment Portfolio and asset management activities.
(b)The decrease in interest expense was primarily related to a decreased weighted-average interest rate on our Credit Facilities (as defined in the Liquidity and Capital Resourcessection below) due to decreases in benchmark index interest rates and decreases to the applicable margin rates resulting from the amendments of our Credit Facilities in April 2025, partially offset by an increase in average borrowings outstanding used to fund a portion of the growth of our Investment Portfolio.
(c)The increase in share-based compensation expense was primarily attributable to incentive compensation awards issued in April 2025.
Net Investment Income
Net investment income for the three months ended September 30, 2025 increased 3% to $86.5 million, or $0.97 per share, compared to net investment income of $84.4 million, or $0.96 per share, in the corresponding period of 2024. The increase in net investment income is the result of the total investment income increase, partially offset by the total expenses increase, each as discussed above. The increase in net investment income per share reflects the increase in net investment income after the impact of the increase in weighted-average shares outstanding for the three months ended September 30, 2025, primarily due to shares issued since the beginning of the comparable period of the prior year through our (i) at-the-market program ("ATM Program"), (ii) dividend reinvestment and direct stock purchase plan ("DRIP") and (iii) equity incentive plans. The increase in net investment income on a per share basis also includes a $0.02 per share increase in investment income considered less consistent or non-recurring in nature.
Distributable Net Investment Income
Distributable net investment income for the three months ended September 30, 2025 increased 3% to $92.7 million, or $1.03 per share, compared to $89.8 million, or $1.03 per share, in the corresponding period of 2024. The increase in distributable net investment income was primarily due to (i) the increase in net investment income as discussed above and (ii) an increase in share-based compensation expense. The increase in distributable net investment income per share reflects the impact of the increase in weighted-average shares outstanding for the three months ended September 30, 2025, as discussed above.

Income Taxes
Main Street's income taxes include excise tax expense at MSCC and federal and state income and other tax expenses at the Taxable Subsidiaries. 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 and Structured Subsidiaries, which are treated as disregarded entities for tax purposes. As a result of its investment activities and dividend policy and activities, MSCC incurs federal excise tax on its estimated undistributed taxable income. The Taxable Subsidiaries incur federal and state income and other taxes related to net investment income resulting from the Taxable Subsidiaries' investment activities. The excise tax expense increase is due to changes in our estimated undistributed taxable income at the RIC, which is taxed at a 4% rate. The net investment income related federal and state income and other tax expenses decrease is due to decreases in taxable net investment income at the Taxable Subsidiaries.
The Taxable Subsidiaries also incur taxes on realized gains (losses) and unrealized appreciation (depreciation). These taxes will change over time due to changes in the valuations of portfolio investments and realized gains and losses, in each case, on our investments owned by the Taxable Subsidiaries.

Income Taxes
Main Street's income taxes include excise tax expense at MSCC and federal and state income and other tax expenses at the Taxable Subsidiaries. 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 and Structured Subsidiaries, which are treated as disregarded entities for tax purposes. As a result of its investment activities and dividend policy and activities, MSCC incurs federal excise tax on its estimated undistributed taxable income. The Taxable Subsidiaries incur federal and state income and other taxes related to net investment income resulting from the Taxable Subsidiaries' investment activities. The excise tax expense increase is due to changes in our estimated undistributed taxable income at the RIC, which is taxed at a 4% rate. The net investment income related federal and state income and other tax expenses increase is due to increases in taxable net investment income at the Taxable Subsidiaries.
The Taxable Subsidiaries also incur taxes on realized gains (losses) and unrealized appreciation (depreciation). These taxes will change over time due to changes in the valuations of portfolio investments and realized gains and losses, in each case, on our investments owned by the Taxable Subsidiaries.

Net Increase in Net Assets Resulting from Operations
The net increase in net assets resulting from operations for the nine months ended September 30, 2025 was $362.3 million, or $4.06 per share, compared with $333.8 million, or $3.87 per share, during the nine months ended September 30, 2024. The tables above provide a summary of the reasons for the change in net increase in net assets resulting from operations for the nine months ended September 30, 2025 as compared to the nine months ended September 30, 2024.
LIQUIDITY AND CAPITAL RESOURCES
Cash Flows
For the nine months ended September 30, 2025, we realized a net decrease in cash and cash equivalents of $47.7 million, which is the net result of $172.8 million of cash provided by our operating activities and $220.4 million of cash used in our financing activities.
The $172.8 million of cash provided by our operating activities resulted primarily from (i) cash proceeds totaling $802.7 million from the sales and repayments of debt investments and sales and return of capital from equity investments and (ii) cash flows that we generated from the operating profits earned totaling $252.4 million, which is our distributable net investment income, excluding the non-cash effects of the accretion of unearned income, PIK interest income, cumulative dividends and the amortization expense for deferred financing costs, partially offset by (i) cash uses totaling $873.9 million for the funding of new and follow-on portfolio investments and (ii) $6.6 million in cash uses related to other assets and liabilities.
The $220.4 million of cash used in our financing activities principally consisted of (i) $253.7 million in dividends paid to our stockholders, (ii) $173.0 million in net repayments from our Credit Facilities, (iii) $150.0 million on the repayment of December 2025 Notes (as defined below), (iv) $10.0 million in purchases of vested stock for employee payroll tax withholdings and (v) $6.6 million for the payment of deferred financing costs, partially offset by (i) $350.0 million in cash proceeds from the issuance of the August 2028 Notes and (ii) $22.9 million in net cash proceeds from equity offerings from our ATM Program.
Capital Resources
As of September 30, 2025, we had $30.6 million in cash and cash equivalents and $1.530 billion of unused capacity under our Credit Facilities (as defined below) which we maintain to support our investment and operating activities. As of September 30, 2025, our NAV totaled $2.9 billion, or $32.78 per share.
As of September 30, 2025, we had $135.0 million outstanding and $1,006.1 million of undrawn commitments under our floating rate multi-year revolving credit facility (the "Corporate Facility"), and we, through MSCC Funding, had $76.0 million outstanding and $524.0 million of undrawn commitments under our special purpose vehicle revolving credit facility (the "SPV Facility" and, together with the Corporate Facility, the "Credit Facilities"), both of which approximated fair value. Availability under our Credit Facilities is subject to certain leverage and borrowing base limitations, various covenants, reporting requirements and other customary requirements for similar credit facilities.
In April 2025, we entered into an amendment to our Corporate Facility to, among other things: (i) decrease the interest rate to the applicable Term Secured Overnight Financing Rate ("SOFR") plus a credit spread adjustment of 0.10% plus (a) 1.775% prior to satisfying certain step-down conditions or (b) 1.65% after satisfying certain step-down conditions, (ii) increase the revolving commitments to $1.145 billion, (iii) increase the accordion feature providing us with the right to request increases in commitments under the facility from new and existing lenders on the same terms and conditions as the existing commitments to up to a total of $1.718 billion and (iv) extend the revolving period and final maturity date through April 2029 and to April 2030, respectively.
In April 2025, we entered into an amendment to our SPV Facility to, among other things: (i) decrease the interest rate to the applicable SOFR plus an applicable margin of (a) 1.95% during the revolving period (from 2.35%), (b) 2.075% for the first year following the end of the revolving period (from 2.475%) and (c) 2.20% for the second year following the end of the revolving period (from 2.60%), (ii) extend the revolving period from through September 2027 to through September 2028, (iii) extend the final maturity date from September 2029 to September 2030 and (iv) decrease the unused fee to 0.40% (from 0.50%) on the unused amount up to 50% (from 35%) of the commitment amount.

In January 2021, we issued $300.0 million in aggregate principal amount of 3.00% unsecured notes due July 14, 2026 (the "July 2026 Notes"). In October 2021, we issued an additional $200.0 million in aggregate principal amount of the July 2026 Notes. The outstanding aggregate principal amount of the July 2026 Notes was $500.0 million as of both September 30, 2025 and December 31, 2024.
In June 2024, we issued $300.0 million in aggregate principal amount of 6.50% unsecured notes due June 4, 2027 (the "June 2027 Notes"). In September 2024, we issued an additional $100.0 million in aggregate principal amount of the June 2027 Notes at a public offering price of 102.134% resulting in a yield-to-maturity of 5.617% on such issuance. The June 2027 Notes issued in September 2024 have identical terms as, and are a part of a single series with, the June 2027 Notes issued in June 2024. The outstanding aggregate principal amount of the June 2027 Notes was $400.0 million and bear interest at a rate of 6.50% per year with a yield-to-maturity of approximately 6.34% as of both September 30, 2025 and December 31, 2024.
In August 2025, we issued $350.0 million in aggregate principal amount of 5.40% unsecured notes due August 15, 2028 (the "August 2028 Notes"). The outstanding aggregate principal amount of the August 2028 Notes was $350.0 million as of September 30, 2025.
In January 2024, we issued $350.0 million in aggregate principal amount of 6.95% unsecured notes due March 1, 2029 (the "March 2029 Notes"). The outstanding aggregate principal amount of the March 2029 Notes was $350.0 million as of both September 30, 2025 and December 31, 2024.
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 $350.0 million of outstanding SBIC debentures guaranteed by the SBA as of September 30, 2025 through our wholly-owned SBICs, which bear a weighted-average annual fixed interest rate of 3.3%, paid semiannually, and mature ten years from issuance. The first maturity related to our SBIC debentures occurs in March 2027, and the weighted-average remaining duration is 4.9 years as of September 30, 2025. 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 maintain SBIC debentures under the SBIC program in the future, subject to periodic repayments and borrowings, in an amount up to the regulatory maximum amount for affiliated SBIC funds.
In May 2024, we repaid the entire $450.0 million principal amount of the issued and outstanding 5.20% unsecured notes (the "May 2024 Notes").
In September 2025, we repaid the entire $100.0 million principal amount of the issued and outstanding 7.84% unsecured notes and the entire $50.0 million principal amount of the issued and outstanding 7.53% unsecured notes (collectively, the "December 2025 Notes") prior to maturity at par value plus the accrued and unpaid interest.
We maintain the ATM 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. During the nine months ended September 30, 2025, we sold 390,990 shares of our common stock at a weighted-average price of $58.91 per share and raised $23.0 million of gross proceeds under the ATM Program. Net proceeds were $22.6 million after commissions to the selling agents on shares sold and offering costs. As of September 30, 2025, there were no share sales transactions that had not settled. In March 2025, we entered into new distribution agreements to sell up to 20,000,000 shares through the ATM Program. As of September 30, 2025, 19,680,372 shares remained available for sale under the ATM Program.
During the year ended December 31, 2024, we sold 2,489,275 shares of our common stock at a weighted-average price of $49.75 per share and raised $123.8 million of gross proceeds under the ATM Program. Net proceeds were $122.2 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 Facilities, and a combination of future issuances of debt and equity capital. Our primary uses of funds will be investments in portfolio companies, operating expenses, cash distributions to holders of our common stock and repayments of note and debenture obligations as they come due.
Table of contents
We periodically invest excess cash balances into marketable securities and short-term investments. The primary investment objective of marketable securities and short-term investments is to generate incremental cash returns on excess cash balances prior to utilizing those funds for investment in our LMM and Private Loan portfolio investments. Marketable securities generally consist of money market funds and certificates of deposit with financial institutions. Short-term portfolio investments consist primarily of investments in secured debt investments and independently rated debt investments.
If our common stock trades below our NAV 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 NAV per share of our common stock at our 2025 Annual Meeting of Stockholders, and have not sought such authorization since 2012, because our common stock price per share has generally traded significantly above the NAV per share of our common stock since 2011. We would therefore need future approval from our stockholders to issue shares below the then current NAV 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 accordance with the 1940 Act, we are allowed to borrow amounts such that our asset coverage ratio, or BDC asset coverage ratio, of our total assets to our total senior securities, which includes borrowings and any preferred stock we may issue in the future, is at least 150% after such borrowing. In January 2008, we received exemptive relief from the SEC to exclude SBA-guaranteed debt securities issued by the Funds and any other wholly-owned subsidiaries of ours which operate as SBICs from the BDC asset coverage ratio which, in turn, enables us to fund more investments with debt capital. Upon receipt of stockholder approval in accordance with the 1940 Act, our BDC asset coverage ratio was reduced from 200% to 150% effective May 3, 2022. As of September 30, 2025, our BDC asset coverage ratio was 261%.
Although we have been able to secure access to additional liquidity, including through our Credit Facilities, public and private 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
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. For a description of recently issued or adopted accounting standards, see Note B.15. - Summary of Significant Accounting Policies - Recently Issued or Adopted Accounting Standardsin the notes to the consolidated financial statements included in Item 1. Consolidated Financial Statementsof this Quarterly Report on Form 10-Q.
Inflation
Inflation has not historically had a significant effect on our results of operations in any of the reporting periods presented herein. However, our portfolio companies have experienced, specifically including over the last few years, as a result of recent geopolitical events, uncertainty with respect to the imposition of tariffs on and trade disputes with certain countries, supply chain and labor issues, and may continue to experience, the increasing 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. These issues and challenges related to inflation are receiving significant attention from our investment teams and the management teams of our portfolio companies as we work to manage these growing challenges. Prolonged or more severe impacts of inflation to our portfolio companies could continue to affect their operating profits and, thereby, increase their borrowing costs, and as a result negatively impact their ability to service their debt obligations and/or reduce their available cash for distributions. In addition, these factors could have a negative effect on the fair value of our investments in these portfolio companies. The combined impacts therefrom in turn could negatively affect our results of operations.
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 Consolidated Balance Sheets. As of September 30, 2025, we had a total of $298.6 million in outstanding commitments comprised of (i) 75 investments with commitments to fund revolving loans that had not been fully drawn or term loans with additional commitments not yet funded and (ii) 11 investments with equity capital commitments that had not been fully called.

Related Party Transactions and Agreements
We have entered into agreements and transactions with the External Investment Manager, MSC Income, Private Loan Fund I and Private Loan Fund II, whereby we have made debt and equity investments and receive certain fees, expense reimbursements and investment income. See Note D - External Investment Manager andNote L - Related Party Transactionsin the notes to the consolidated financial statements included in Item 1. Consolidated Financial Statementsof this Quarterly Report on Form 10-Q for additional information regarding these related party transactions and agreements.
In addition, we have a deferred compensation plan, whereby non-employee directors and certain key employees may defer receipt of some or all of their fees and cash compensation, subject to certain limitations. See Note L - Related Party Transactionsin the notes to the consolidated financial statements included in Item 1. Consolidated Financial Statementsof this Quarterly Report on Form 10-Q for additional information regarding the deferred compensation plan.
Recent Developments
In November 2025, we declared a supplemental dividend of $0.30 per share payable in December 2025. This supplemental dividend is in addition to the previously announced regular monthly dividends that we declared of $0.255 per share for each month of October, November and December 2025 or total regular monthly dividends of $0.765 per share for the fourth quarter of 2025, resulting in total dividends declared for the fourth quarter of 2025 of $1.065 per share.
In November 2025, we also declared regular monthly dividends of $0.26 per share for each month of January, February and March of 2026. These regular monthly dividends equal a total of $0.78 per share for the first quarter of 2026, representing a 4.0% increase from the regular monthly dividends paid in the first quarter of 2025. Including the regular monthly and supplemental dividends declared for the fourth quarter of 2025 and first quarter of 2026, we will have paid $47.935 per share in cumulative dividends since our October 2007 initial public offering.
